Mit einem Register der in den Novellen und Romanen Fontanes vorhandenen Bibelbezüge N2 - In der vorliegenden Arbeit wird die Funktion verschiedener Bibelbezüge im Romanwerk Theodor Fontanes untersucht. Dabei wird die These vertreten, dass Fontanes Verweise auf biblische Texte nicht etwa bloß als theologische Positionierungen zu lesen seien, sondern dass er die Bibel als Speicher an kulturellem Wissen in Form von Narrativen, Personen, Geflügelten Worten etc. begreift, den er in seiner Leserschaft voraussetzen kann und durch den er Themen wie Normativität und Diskursivität mit einer besonderen Tiefe in der Spannung von Text und Prätext verhandeln kann. Im Zentrum der Untersuchung stehen dabei Verwendungen von Bibelbezügen als hochkommunikative Diskursschablonen für poetologische Selbstreflexionen sowie für politische oder frömmigkeits-praktische Kontroversen. N2 - The aim of this treatise is to discuss various functions of references to biblical writings which can be observed in Theodor Fontane’s novels. Analyzing various references and allusions (especially in “Grete Minde”, “Quitt” and “Der Stechlin”), it is maintained that Fontane does not use bible-references as theological statements, but with a wide range of scopes and functions: Providing sujés, situations and constellations which are well known by the typical 19th century audience, references to biblical texts can be used to discuss topics like normativity and discursivity as well as to offer a pattern for political and religious discurses or poetological reflections.

The study attempts to elucidate the formation of Halacha on this question according to the Responsa literature starting from the Rishonim (the early authorities) period (11th till 15th centuries) and up to the Acharonim (the later authorities) period (from the 16th century and onwards), and concentrating primarily on the modern era and last century. The aim of this research is to examine the process of reasoning and decision making of religious authorities, dealing with the penetration of technological and scientific advancements into a closed and conservative society. Our analysis shows how rabbis are facing the conflict between medical and social necessity to access advanced medical treatments and fear of social transitions and religious implications, caused by such technologies. In addition to analysis of the Orthodox Responsa, this study surveys also the opinion of rabbis in Reform and Conservative Judaism. N2 - תקציר מצוות הפריון הינה אחת מן המצוות החשובות ביהדות ומגדירה במובנים רבים את מהות קיומו של האדם היהודי הדתי. זוגות דתיים אשר סובלים מבעיית פריון נקרעים לא פעם בין מחוייבותם הדתית והלחץ החברתי בקהילתם לבין אי יכולתם להביא ילדים לעולם בדרך טבעית. החל מאמצע המאה ה 20- הפכו טכנולוגיות פריון רפואיות לנגישות לציבור הרחב בישראל ובעולם והובילו למהפכה חברתית אשר אפשרה לזוגות חשוכי ילדים להגשים את חלומם בפעם הראשונה ולהפוך להורים. פריצת דרך רפואית זו לא נעלמה מעיני הציבור הדתי על זרמיו השונים וגרמה לטלטלה בתפיסת עולמם של מנהיגיהם, אשר נדרשו לתת מענה הלכתי הולם המאזן בין רווחת קהילותיהם לבין שמירה על ערכי ומצוות הדת היהודית. על רקע תמורות אלו התפתח שיח הלכתי ואקדמי חשוב ומעניין באשר למקומה של טכנולוגיה מודרנית בחברה המתנהלת על פי קודים מסורתיים. עם זאת, הדיאלוג החי המתקיים בין מנהיגי היהדות לבין קהילותיהם, אשר מתועד כאוסף שאלות ותשובות (שו"ת) לבעיות הלכתיות אקטואליות בתחום הפריון, לא נחקר דיו. עבודתנו עוסקת במחקר ספרות השו"ת ובגישת פוסקי ההלכה להסתייעות בטכנולוגיית ההזרעה המלאכותית ובטיפולי פוריות חדשניים נוספים שהתפתחו בעקבותיה כגון הפריה חוץ גופית, פונדקאות ותרומת ביציות. העבודה סוקרת את התגבשות ועיצוב ההלכה בשאלה זו, כפי שעולה מספרות השו"ת החל מתקופת הראשונים (המאות ה 11- עד ה- 16 ) ועד לפוסקים מתקופת האחרונים (המאה ה- 16 ואילך), ומתמקדת בעיקר בתקופה המודרנית של המאה האחרונה. במרכז העבודה יעמדו מעמדם ההלכתי של האם והוולד בעקבות שימוש בהזרעה והפריה מלאכותית וכן השלכותיהן ההלכתיות של השימוש הרפואי בזרע. תרומתו של מחקר זה הינה בהצגת וניתוח התמודדות הפוסקים עם העימות הערכי וההלכתי שמעוררות תמורות במבנה המשפחה ובדפוסי הורות מסורתיים כתוצאה משימוש הולך וגובר בטכנולוגיות פריון מתקדמות בחברה המודרנית. יתר על כן, מחקר זה מרחיב את הדיון ההלכתי אל מעבר לעמדות הפוסקים ביהדות האורתודוקסית, הנצמדים לעקרונות ההלכה ההיסטורית, ומציג לראשונה אף את קשת הדעות של רבנים המשתייכים לזרמי היהדות המתקדמת והקונסרבטיבית, הדוגלים בפיתוח ההלכה והתאמתה למציאות החיים המשתנה. כך, מעניקה עבודת מחקר זו תמונה שלמה ומקיפה יותר באשר להתמודדות הרבנים עם שאלת ההזרעה המלאכותית ומציגה את רב גוניותה של ההלכה כפי שמשתקפת בזרמי היהדות השונים בישראל ובתפוצות. העבודה מחולקת לשישה חלקים אשר יפורטו בקצרה להלן. חלק ראשון - מבוא לשאלת ההזרעה המלאכותית בספרות השו"ת חלק זה מהווה מבוא והקדמה תיאורטית ומחקרית לשאלת ההזרעה המלאכותית ומטרתו לצייד את הקורא ברקע ההיסטורי ובכלים המחקריים הדרושים להמשך העבודה. הפרק הראשון סוקר מצוות דתיות והשקפות תרבותיות בנוגע לילודה בחברה היהודית ואילו הפרק השני מניח יסודות מתודולוגיים והיסטוריים הנחוצים לחקר שאלת ההזרעה המלאכותית בספרות השו"ת. פרק ראשון - מצוות דתיות והשקפות תרבותיות בנוגע לילודה בחברה היהודית פרק זה מציג את המשנה האידיאולוגית העומדת בבסיס ההצדקה ההלכתית להתרתם של טיפולי הפוריות. הפרק דן בחשיבות מצוות הפריון כפי שעולה ממקורות הלכתיים קדומים וברקע ההיסטורי והתרבותי למרכזיותה של מצווה זו ומצוות נלוות לה בדת היהודית. הפרק מדגים כיצד עיצבה חשיבות המצווה את דפוס המשפחה היהודית לאורך ההיסטוריה ועד לימינו ומסתיים בדיון קצר בשאלות רפואיות מוסריות העולות מהנגשת טכנולוגיות פריון מתקדמות במדינת ישראל המודרנית. פרק שני - יסודות מתודולוגיים והיסטוריים בחקר שאלת ההזרעה המלאכותית בספרות השו"ת בפרק זה מוצגים תחילה מטרות ושיטות המחקר אשר נבחרו לשם ניתוח הפסיקה בשאלת ההזרעה המלאכותית. מכיוון שהעבודה עוסקת בשאלה רפואית חדשנית והשפעתה על העולם הדתי, יערך מחקר זה תוך שימוש בניתוח רב מימדי המשלב מספר שיטות מחקר ובראשן השיטה הדוגמטית-היסטורית, כמו גם בניתוח ביקורתי של שיקולי המדיניות העומדים בבסיס שיקולי הפוסקים לפי אסוכלת הריאליזים ההלכתי. לאחר מכן נסקרים ונידונים המקורות ההיסטוריים העיקריים אשר עוסקים בהתעברות על טבעית באמבט או באמצעות שכיבה על סדינים והעומדים בבסיס הכרעות הפוסקים בהשלכות הזרעה מלאכותית על מעמדם ההלכתי של האישה והילוד. חלק שני- ספרות השו"ת האורתודוקסית בשאלת הזרעה מלאכותית מן הבעל חלקו שני של המחקר עוסק בניתוח ספרות השו"ת האורתודוקסית בשאלת הזרעה מלאכותית מן הבעל ובוחן את התפתחותו הרעיונית של איסור השחתת זרע ואת עמדות הפוסקים בשאלת הזרעה מלאכותית מן הבעל כפי שנידונה בספרות השו"ת. פרק ראשון - התפתחותו הרעיונית של איסור השחתת זרע בפרק זה נסקרים מקורותיו ההיסטוריים של האיסור להשחתת זרע. איסור זה נושק לכל תחומי חייו של הזוג הדתי ובעיקר לתחום המיניות והפריון ובעל השפעה מהותית על מגבלות הצניעות שהוחלו בעקבותיו על המיניות הגברית. קיים ויכוח בין החוקרים האם נובע האיסור מן המקורות העתיקים כגון התלמוד או לחילופין התעצם בעקבות החמרות הרבנים. מחקרינו מציע כי האפשרות השניה היא הסבירה יותר. חכמי התלמוד מפגינים גישה מקלה כלפי האיסור אך מביעים סלידה מהוצאת זרע לבטלה מתוך חשיבה חסידית או אמונה כי עיסוק בעינוג מיני עצמי עלול להסיט את האדם מקיום מצוות הפריון. לעומת זאת, בספרות הקבלה ובמיוחד בזוהר ניכרת החמרה במימדי האיסור החודרת מאוחר יותר אל עולם ההלכה. פרק שני - דיון בהזרעה מן הבעל בספרות השו"ת הפרק דן בפסיקותיהם של רבנים בולטים בזרם האורתודוקסי בשאלת ההזרעה מן הבעל. בספרות השו"ת האורתודוקסית ניכרת השפעתו של איסור הוצאת זרע לבטלה על שיקולי הפוסקים באם להתיר את הטיפול בהזרעה מלאכותית מן הבעל. פוסקים מקלים כגון הרבנים פיינשטיין, נבנצל ויוסף מייחסים משקל רב יותר לחשיבות מצוות הפריון ומצמצמים בשל כך את תחולת האיסור. לעומתם, פוסקים מחמירים ובראשם הרבנים טננבוים, קוק, עוזיאל, הדאיה ולדנברג מתנגדים לטיפולי פוריות מחשש השחתת זרע ובשל השלכותיה הרוחניות של העבירה על האיסור. שאלה מהותית נוספת בשיח ההלכתי בה נחלקו הרבנים הינה באשר לאפשרות קיומה של מצוות הפריה והרביה באמצעות הריון שהושג בסיוע רפואי. פוסקים מדור האחרונים, כגון הרבנים טננבוים, סגל ואזולאי (החיד"א), ובעקבותיהם פוסקים בולטים במאה ה- 20 וה- 21 כמו הרבנים עוזיאל, הדאיה, ולדנברג וקניבסקי סברו כי ניתן לקיים את המצווה באופן טבעי בלבד. לעומת זאת, הרבנים נבנצל, יוסף, וינברג ואוירבך ייחסו חשיבות רבה יותר לכוונת העושה ולתוצאה המיוחלת של ההריון אשר מגשימה לדעתם את הרציונל העומד בבסיס מצוות הפרייה הרבייה ובמצוות ישוב העולם. שאלה נוספת המתעוררת בעניין הזרעה מן הבעל ונידונה בפרק זה עוסקת בבעיית העקרות ההלכתית. התעקשות הרבנים לשמור על הלכות הנידה במתכונתן המסורתית חושפת נשים דתיות לאי ודאות באשר לטהרתן ומכפיפה את חיי המין והפריון של משפחות שלמות למרות הסמכות הרבנית. חלק שלישי- ספרות השו"ת האורתודוקסית בשאלת הזרעה מלאכותית מתורם חלקו השלישי של המחקר עוסק בדיון ההלכתי האורתודוקסי בשאלת ההזרעה המלאכותית מתורם יהודי או נוכרי לאישה נשואה. מרבית הפוסקים הסתייגו מתרומת זרע לאישה נשואה מתורם יהודי כמו גם מנוכרי משיקולים הלכתיים ואידיאולוגיים. פרק ראשון - שאלת ההזרעה המלאכותית מתורם יהודי תרומת זרע מתורם יהודי זר מעלה חששות הלכתיים רבים לגבי מעמדה ההלכתי של האישה כגון ניאוף וקיום מצוות הייבום והחליצה. כמו כן הועלו חששות לגבי יחוסו וכשרותו ההלכתית של הקטין כגון חשש ממזרות, גילוי עריות בין ילדי התורם, פגיעה במעמד הכהונה ובעיות בתחום המעמד האישי בשל אי ודאות לגבי זהות התורם. בנוסף, משליכה הכרעה בשאלות אלה על זכאות הקטין לזכויות סוציאליות המגיעות לו מאביו, כגון הזכות למזונות ולירושה. פסיקת ההלכה במאה האחרונה אימצה את עמדתו של הרב פיינשטיין, לפיה רק הריון הנובע ממגע מיני ישיר בין אישה נשואה לגבר זר, בניגוד להזרעה מלאכותית, יכול לפגוע במעמד האישה והילוד. עם זאת, פוסקים רבים אסרו לבצע הזרעה מלאכותית מגבר יהודי מטעמי זהירות, בגין חששות אלו. פרק שני - הזרעה מלאכותית מתורם לא יהודי לאישה נשואה על אף שבמקרה של תרומת זרע מנוכרי נעדר הילוד יחוס לאביו הנוכרי וכשרותו נקבעת על פי מעמד האם בלבד, מסתייגים פוסקים רבים מן הפעולה. הפוסקים מונים טיעונים רבים לאיסור תרומת זרע מגבר נוכרי וביניהם חילול השם, פגיעה בביצוע מנהג הייבום והחליצה, ספקות לגבי זכויות הירושה, עידוד ההפקרות המינית ופגיעה ביציבות התא המשפחתי המסורתי. בנוסף חוששים הם מבלבול לגבי זהות אבי הילוד ופגיעה במעמד הכהונה. במהלך המאה ה- 20 ניכרת מגמה בקרב פוסקים העוסקים בקבלה לייחוס תכונות שליליות לזרע נוכרי, אשר עוברות לילוד ובאופן זה פוגעות בקדושת העם היהודי. מעבר לשאלות ההלכתיות מועלים בפרק זה קשיים אתיים אשר מעוררת תרומת זרע אנונימית, המונעת מן הילוד לברר את שורשיו הביולוגיים. חלק רביעי- יחס הפסיקה האורתודוקסית לשינויים במבנה המשפחה המסורתית בעקבות שימוש בטכנולוגיות פריון חלק זה מנתח את יחס הפסיקה האורתודוקסית לשינויים במבנה המשפחה המסורתית בעקבות שימוש בטכנולוגיות פריון ומורכב משלושה פרקים: הזרעה מלאכותית לאישה פנויה, הפריה חוץ גופית והקמת משפחה אלטרנטיבית בפרספקטיבה הלכתית אורתודוקסית. פרק ראשון - הזרעה מלאכותית לאישה פנויה המוסכמה ההלכתית הינה כי ילדה של אישה פנויה לא ייחשב לממזר, אפילו אם אביו הביולוגי הוא יהודי. למרות זאת אסרו פוסקים מסויימים על הזרעה מלאכותית במקרה זה בגין חששות לייחוס הילוד, גילוי עריות וגזילת ירושת שאר האחים. חלק מן הפוסקים קוראים לאסור הזרעה מלאכותית לאישה פנויה בשם טובת הילד ולא מסיבות הלכתיות. אפשרות נוספת אשר השלכותיה ההלכתיות נידונות בפרק זה הינה ביצוע הזרעה מלאכותית באישה רווקה או אלמנה באמצעות שימוש בזרעו של אדם שנפטר. חשוב לציין כי השימוש בטכנולוגיה זו שנוי במחלוקת בקרב הרבנים בגין החשיבות אותה מייחסת היהדות לערך כבוד המת. פרק שני - הפריה חוץ גופית הפריית מבחנה יכולה להתבצע בין בני זוג נשואים בסיוע או ללא היזקקות לתרומת ביצית או זרע. פוסקים אשר התירו את השימוש בטכנולוגיה זו הביעו את חששותיהם בנוגע להשלכותיה ההלכתיות של הפריה החוץ גופית בשל הקושי לפקח על התהליך, הנעשה מחוץ לגוף האדם. מתנגדי הפריית המבחנה סברו כי היא מתערבת במלאכת הבריאה האלוהית ועשויה לדרדר את האנושות מבחינה מוסרית לתכנון ולשיבוט בני אדם. הפריה חוץ גופית מעוררות שאלות הלכתיות חדשניות ובראשן שאלת הגדרת האמהות, כגון במקרי פונדקאות ותרומת ביציות, מהן הסתייגו מרבית פוסקי הדור במאה ה 20- . הקביעה שאומצה בשיח ההלכתי העכשווי גורסת כי אמו של התינוק תהיה האישה שילדה אותו, גם אם נולד מתרומת ביצית. הכרעה זו מובלעת ברציונל החוקים המסדירים את הפונדקאות במדינת ישראל ואשר מטילים מגבלות הלכתיות על בחירת הפונדקאית לשם מניעת חשש ממזרות או שאלה לגבי יהדותו של הילוד. פרק שלישי - הקמת משפחה אלטרנטיבית בפרספקטיבה הלכתית אורתודוקסית קיימת בעיה הלכתית מהותית במיסוד הקשר החד-מיני ביהדות האורתודוקסית. ספרות השו"ת האורתודוקסית אינה עוסקת במפורש בשאלת השימוש בהזרעה מלאכותית לצורך הקמת המשפחה החד- מינית. עם זאת, ניתן ללמוד רבות על גישת האורתודוקסיה משו"תים עכשוויים העוסקים בתופעת ההומוסקסואליות ובקיום מצוות הפריון במקרה זה. הדעה הרווחת היום בקרב הפוסקים הינה כי קשר חד- מיני אסור, כמו גם מיסודו וקיום מצוות פרו ורבו במסגרת זו. בשל כך ניתן להסיק כי הרבנים לא יתירו שימוש בהזרעה מלאכותית לצורך קיום מצוות הפריון במשפחה חד-מינית. חלק חמישי- עמדת רבני הזרם רפורמי והקונסרבטיבי בשאלת ההזרעה המלאכותית חלק זה מתמקד בזרמי היהדות הרפורמית והקונסרבטיבית ומציג את עמדות רבני זרמים אלו בעניין ההזרעה המלאכותית תוך עימותן עם עמדות פוסקים אורתודוקסיים. פרק ראשון - עמדת הרבנות הרפורמית בשאלת ההזרעה המלאכותית חשיבות מצוות הפריון מודגשת בספרות השו"ת הרפורמית, אולם טיפולי פוריות אינם מתפרשים כדרך היחידה לקיומה. על מנת שלא לפגוע במרקם החיים המשפחתי מוצעת לא אחת חלופת האימוץ לטיפולי פוריות מייגעים, תרומת זרע והיזקקות לפונדקאות ותרומת ביציות. שאלת השחתת הזרע, המעסיקה רבות את רבני הזרם האורתודוקסי, כמעט שאינה נידונה על ידי רבני הזרם הרפורמי. באשר לשאלות של כשרות וייחוס, רווחת הדעה בקרב רבנים רפורמיים בולטים כגון הרב הומולקה ורומיין, כי מעמד הממזרות איננו רלוונטי עוד בימינו ולכן ממילא לא נשקפת לילד הסכנה שזכויותיו הדתיות ייפגעו. ועד הרבנים הרפורמיים התיר לחבריו לפעול לפי שיקול דעתם בעניין עריכת טקס נישואין דתי בין בני זוג בני אותו המין, תוך הדגשת הויכוח הפנימי בתנועה ומורת הרוח הקיימת מצד הזרמים האחרים ביהדות. פרק שני - עמדת הרבנות הקונסרבטיבית בשאלת ההזרעה המלאכותית עמדת רבני היהדות הקונסרבטיבית גורסת כי טיפולי פוריות מהווים רשות, אך אינם בגדר חובה עבור זוגות הרוצים לקיים את מצוות הפריה והרבייה ומתקשים בכך. בדומה לביטולה של גזירת הממזרות בזרם הרפורמי, בוטל מעמד זה לאחרונה גם ביהדות הקונסרבטיבית. אוננות במסגרת טיפולי פוריות הינה מותרת ואיננה מוגדרת כהשחתת זרע לבטלה ואף מותרת גם לשם תרומת זרע של יהודי לאישה לא יהודיה. כמו בזרם הרפורמי גם כאן מונחת אופציית האימוץ על סדר היום. כנסת הרבנים הקונסרבטיבים בארצות הברית קיבלה החלטה ברוב זעום להכרה אזרחית בהומוסקסואלים, אך עם זאת השאירה על כנו את האיסור לקדש זוגות אלה. אין בהחלטה זו הכרה הלכתית בזוגיות החד-מינית אלא קבלתם החברתית של זוגות אלה ועידודם להשתלב בקהילות הקונסרבטיביות. חלק שישי - סיכום ודיון בהשלכות המחקר בחלקו השישי והאחרון בעבודת מחקר זו נסכם ונדון בהשלכותיה האתיות והגלובליולת של הפסיקה ההלכית בשאלה הנידונה. כפי שניתן לראות מעבודת מחקר זו, הרבנים האורתודוקסיים מסתמכים בהכרעותיהם בעיקר על שיקולים הלכתיים ופחות על שיקולים אתיים ואוניברסליים. מחד, מסתייגים פוסקים אורתודוקסיים מסויימים משימוש לרעה בטיפולי פוריות, אך מאידך מוכנים הם בשם עקרונות דתיים להתיר שימוש בטכנולוגיות אלו במקרים שאינם מצריכים זאת משיקולים רפואיים. במיוחד בולט העדר התייחסותם של הפוסקים האורתודוקסיים לשיקולים מוסריים חברתיים, כמו גם לרצונה ולרווחתה של האישה העוברת טיפולי פוריות. לעומתם מביעים רבני הזרם הרפורמי והקונסרבטיבי את דאגתם להשלכותיהם של טיפולים אלו על נשים הנזקקות להתערבות רפואית מעין זו לשם התעברות ואלו העובדות בתעשיית הפריון. יש לציין כי הדיון ההלכתי עוסק בהיבט צר בלבד של שאלת ההזרעה המלאכותית ואינו נוגע ברבות מן השאלות המורכבות שמעוררות טכנולוגיות פריון מתקדמות. עם זאת הדיון ההלכתי הינו חשוב ביותר ומציף אף שאלות נוספות בדבר הסכנה הצפויה מהפיכתן של טכנולוגיות אלה לכלי שרת בידי אידאולוגיות דתיות או פוליטיות.

T1 - О высоком и низком: пространственная семантика абстрактных и конкретных существительных JF - Tomsk state university journal N2 - Aim and material: In the present study, the data of the rating study presented earlier, where participants estimated the position of an object or phenomenon in vertical space by using the seven-point Likert scale, are used in order to systematically describe spatial information included in language units of different semantic categories. Background: The role of spatial semantics in language understanding is assumed by modern cognition theories and confirmed in experimental studies. Hypotheses: Based on conceptual metaphor theory, a number of hypotheses are proposed in the present study: different semantic categories of nouns (e.g., tools vs. animals vs. emotions etc.) should significantly differ in their spatial semantics as well; different semantic categories of abstract nouns (e.g., mental states vs. emotions vs. physical sensations) should also differ in their spatial semantics, as the latter is included in their conceptual structure; mental states and phenomena (e.g., imagination, thought or memory) should have higher values (i.e., be located higher in the virtual subjective space) than any other abstract concepts; emotional concepts (e.g., love, disgust or happiness) should be located higher than physical sensations (e.g., pain or softness); positive emotions (like joy or euphoria) should be located higher than negative ones (like feeling of guilt or disappointment). Methods: Statistical methods (parametric and non-parametric ones) are used in order to test the hypotheses. As additional cross-testing methods corpora data and expert assessment are included. Results: The results of the study confirmed all the hypotheses. A number of additional regularities were revealed: in general, abstract concepts get higher values on a scale, i.e., are located higher in the virtual subjective space than concrete ones; tool concepts are related more to the lower space, unlike sound concepts that are related to higher space. No difference was found between action concepts (like attack or running) and physical sensations. Discussion: The results obtained can also be explained in terms of other theories within the embodied cognition framework, as it is discussed in the conclusion (words as social tools by A. Borghi and F. Binkofski; ideas by G. Vigliocco and neurosemantic approach by F. Pulvermuller). The need in an integrative model and larger studies with other semantic categories is underlined.

Die Literaturrecherche machte deutlich, dass der Berufseinstieg eine besonders wichtige Phase für die berufliche Sozialisation darstellt. Die Nutzung von Lerngelegenheiten wurde empirisch noch nicht sehr oft untersucht vor allem nicht im Zusammenhang mit individuellen Determinanten und die Kooperation meist nur unter dem Fokus der Bedeutung für die Schule. An der empirischen Untersuchung nahmen 223 berufseinsteigende Lehrkräfte aus dem Allgemeinen Pflichtschulbereich in Niederösterreich teil, die verpflichtend in den ersten beiden Dienstjahren Fortbildungen besuchen müssen. Diese Situation ist einzigartig in Österreich, da es nur in diesem Bundesland seit 2011 eine verpflichtend zu besuchende Berufseinstiegsphase gibt. Ab 2019 wird es in Österreich eine Induktionsphase für alle Lehrkräfte geben, die in den Beruf einsteigen. Mit Hilfe von Strukturgleichungsmodellen wurden die Zusammenhänge untersucht und es zeigte sich, dass es diese in allen Bereichen gibt. Am Ende konnte ein neues Theoriemodell zur Nutzung von Lerngelegenheiten abgeleitet werden, das sich in Theorien zu professionellen Kompetenzentwicklung und zu Lernen in Aus-, Fortund Weiterbildung einordnen lässt. N2 - The current study concentrates on the career entry of teachers and examines all correlations between the use of learning opportunities, social cooperation, individual determinants and self-assessments of competences, which were analysed in this compilation for the first time. The literature research clarified, that the career entry is a very important phase for the job socialisation. The use of learning opportunities has not been empirically studied very often particularly not in the context of individual determinants and cooperation has mostly been studied only focusing the relevance for school. The empirical study involved 223 novice teachers from compulsory schools in Lower Austria, who must attend an obligatory supporting system in their first two years of their teaching career. This situation is unique in Austria, as only this federal state provides an obligatory career entry programme. As of 2019 there will be an induction phase for all teachers, who start their teaching career. With the help of structural equation models the correlations were analysed and it showed, that there were correlations between all component parts. At the end it was possible to deduct a new theory model for learning opportunities, which can be part of theories concerning professional development of competences and theories about learning in basic, advanced and vocational education and training.

Darüber hinaus hat er drei persische Handschriften käuflich erworben. Das umfangreichste Stück ist der chinesische Roman Geschichte der Drei Reiche. Humboldt hatte den Altphilologen und Kenner des Armenischen und Chinesischen, Carl Friedrich Neumann, gebeten, diese Titel zu katalogisieren. Als die Liste im Druck erschien (während Neumann sich auf einer Chinareise befand), führten die Monita zu einer Gelehrtenfehde. Danach gerieten die Bücher, eine bunte Mischung, bald in Vergessenheit. Vorliegender Artikel gibt eine Liste auf Grund des heutigen Befundes in der Staatsbibliothek zu Berlin, für die der Sammler die Bücher von Anfang an bestimmt hatte, wie mehrere Beischriften belegen. N2 - Humboldt was presented with a number of books and manuscripts in Mongol, Calmuck, Armenian, Chinese, Tibetan and Manchu on his trip through Russia in 1829. In addition he bought three Persian manuscripts. The largest item was the Chinese novel History of the Three Kingdoms. Humboldt asked the classical philologist and Armenian and Chinese scholar Carl Friedrich Neumann to catalogue these books. When the list was published (while Neumann was absent on a trip to China), the criticism led to a scholarly feud. Afterwards the books, a rather mixed bag so to speak, soon fell into oblivion. The present article provides an analysis and catalogue of the material on the basis of the evidence in the Berlin State Library to which the collector had donated it immediately after his return from Russia as documented by several autograph notes.

El texto más extenso fue la novela china La historia de los tres imperios. Humboldt pidió al filólogo clásico y conocedor del armenio y chino Carl Friedrich Neumann que catalogase estos libros. Cuando la lista fue publicada (mientras Neumann estaba de viaje en China) la reacción crítica resultó en una disputa académica. Luego los libros, una mezcla abigarrada, cayeron en el olvido. El presente artículo da un análisis y un catálogo del material a base de la evidencia en la Biblioteca Estatal de Berlín, a la que el coleccionista donó los libros inmediatamente después de regresar de Rusia, como documentan varias notas autógrafas.

Early Precambrian rocks were previously reported from several metamorphic complexes in the Kyrgyz Tianshan orogenic belt, mainly based on multigrain conventional zircon dating, but the present study only confirmed such rocks at one site, namely in the Kuilyu Complex of eastern Kyrgyzstan. New single grain SHRIMP II zircon ages, geochemical data, and whole-rock Nd isotopic compositions for granitoid gneisses of the Kuilyu Complex elucidate the age, origin and tectonic settings of this oldest continental fragment in the Tianshan. The Kuilyu Complex is part of the basement in the Ishim - Middle Tianshan microcontinent. It consist of a strongly deformed and metamorphosed supracrustal assemblage of paragneisses and schists which are tectonically interlayered with amphibolites, migmatites and granitoid gneisses. Our zircon dating indicates that the Kuilyu Complex contains two suites of Palaeoproterozoic granitoid gneisses with magmatic protolith ages of ca. 2.32-2.33 Ga and 1.85 Ga. Granitoid magmatism at 1.85 Ga was almost immediately followed by amphibolite-facies metamorphism at ca 1.83 Ga, evidenced by growth of metamorphic zircon rims. The older, ca 2.3 Ga granitoid gneisses chemically correspond to calc-alkaline, metaluminous, I-type magnesian quartz diorite and granodiorite. The protolith of the younger, ca. 1.85 Ga granite-gneiss is an alkalic-calcic, metaluminous to peraluminous, ferroan medium-grained porphyric granite with chemical features resembling A-type granites. The 2.3 Ga and 1.85 Ga granitoid gneisses have slightly to distinctly negative initial epsilon(Nd) values of -1.2 and -6.6, and similar depleted mantle Nd model ages of 2.7-2.6 Ga, which imply melting of Neoarchaean continental crust. The zircon age patterns of the Kuilyu Complex resemble those of exposed rocks in the Tarim Craton, where episodes of granitoid magmatism at ca. 2.3-2.4 and 1.85 Ga, followed by amphibolite-facies metamorphism at ca 1.85 Ga, are also recorded. Similarities in the early Precambrian magmatic and metamorphic episodes as well as similar histories during the Neoproterozoic and early Palaeozoic suggest that the Ishim-Middle Tianshan microcontinent was rifted off the Tarim Craton. Similar age patterns also suggest possible tectonic links of the Kuilyu and Tarim continental blocks with the Baidrag Block of central Mongolia. In contrast, substantial differences in age and Precambrian evolution between the Anrakhai block of southern Kazakhstan and the Kuilyu Complex argue against a previous connection and suggest the former to represent an independent continental terrane. Current data show that early Precambrian rocks in the western CAOB outside Tarim only occur at two sites, namely in the Anrakhai Complex of southern Kazakhstan and in the Kuilyu Complex of eastern Kyrgyzstan.

A1 - Bernabeu, Guillermo T1 - XMM-Newton spectroscopy of the accreting magnetar candidate 4U0114+65 JF - Astronomy and astrophysics : an international weekly journal N2 - Methods. We analysed the energy-resolved light curve and the time-resolved X-ray spectra provided by the EPIC cameras on board XMM-Newton. We also analysed the first high-resolution spectrum of this source provided by the Reflection Grating Spectrometer. Results. An X-ray pulse of 9350 +/- 160 s was measured. Comparison with previous measurements confirms the secular spin up of this source. We successfully fit the pulse-phase-resolved spectra with Comptonisation models. These models imply a very small (r similar to 3 km) and hot (kT similar to 2-3 keV) emitting region and therefore point to a hot spot over the neutron star (NS) surface as the most reliable explanation for the X-ray pulse. The long NS spin period, the spin-up rate, and persistent X-ray emission can be explained within the theory of quasi-spherical settling accretion, which may indicate that the magnetic field is in the magnetar range. Thus, 4U0114+65 could be a wind-accreting magnetar. We also observed two episodes of low luminosity. The first was only observed in the low-energy light curve and can be explained as an absorption by a large over-dense structure in the wind of the B1 supergiant donor. The second episode, which was deeper and affected all energies, may be due to temporal cessation of accretion onto one magnetic pole caused by non-spherical matter capture from the structured stellar wind. The light curve displays two types of dips that are clearly seen during the high-flux intervals. The short dips, with durations of tens of seconds, are produced through absorption by wind clumps. The long dips, in turn, seem to be associated with the rarefied interclump medium. From the analysis of the X-ray spectra, we found evidence of emission lines in the X-ray photoionised wind of the B1Ia donor. The Fe K alpha line was found to be highly variable and much weaker than in other X-ray binaries with supergiant donors. The degree of wind clumping, measured through the covering fraction, was found to be much lower than in supergiant donor stars with earlier spectral types. Conclusions. The XMM-Newton spectroscopy provided further support for the magnetar nature of the neutron star in 4U0114+65. The light curve presents dips that can be associated with clumps and the interclump medium in the stellar wind of the mass donor.

T1 - X- ray study of bow shocks in runaway stars JF - Monthly notices of the Royal Astronomical Society N2 - Massive runaway stars produce bow shocks through the interaction of their winds with the interstellar medium, with the prospect for particle acceleration by the shocks. These objects are consequently candidates for non-thermal emission. Our aim is to investigate the X-ray emission from these sources. We observed with XMM-Newton a sample of five bow shock runaways, which constitutes a significant improvement of the sample of bow shock runaways studied in X-rays so far. A careful analysis of the data did not reveal any X-ray emission related to the bow shocks. However, X-ray emission from the stars is detected, in agreement with the expected thermal emission from stellar winds. On the basis of background measurements we derive conservative upper limits between 0.3 and 10 keV on the bow shocks emission. Using a simple radiation model, these limits together with radio upper limits allow us to constrain some of the main physical quantities involved in the non-thermal emission processes, such as the magnetic field strength and the amount of incident infrared photons. The reasons likely responsible for the non-detection of non-thermal radiation are discussed. Finally, using energy budget arguments, we investigate the detectability of inverse Compton X-rays in a more extended sample of catalogued runaway star bow shocks. From our analysis we conclude that a clear identification of non-thermal X-rays from massive runaway bow shocks requires one order of magnitude (or higher) sensitivity improvement with respect to present observatories.

Provided with new high-resolution, high signal-to-noise spectra from the Keck observatory, we determine the orbital parameters for both the primary WR and the secondary, yielding respective projected orbital velocity amplitudes of 88.1 ± 3.8 km s−1 and 79.2 ± 3.1 km s−1 and implying a mass ratio of 1.1 ± 0.1. We then apply the shift-and-add technique to disentangle the spectra and obtain spectra compatible with a WN7ha and an O4-6 star. Considering an orbital inclination of ∼67°, derived from previous polarimetry observations, the system's total mass would be a mere 2–3M⊙⁠, an unprecedented result for a putative massive binary system. However, a system comprising a 37M⊙ secondary (typical mass of an O5V star) and a 33M⊙ primary (given the mass ratio) would infer an inclination of ∼18°. We therefore reconsider the previous methods of deriving the orbital inclination based on time-dependent polarimetry and photometry. While the polarimetric results are inconclusive requiring better data, the photometric results favour low inclinations. Finally, we compute WR 148’s space velocity and retrace the runaway's trajectory back to the Galactic plane (GP). With an ejection velocity of 198 ± 27 km s−1 and a travel time of 4.7 ± 0.8 Myr to reach its current location, WR 148 was most likely ejected via dynamical interactions in a young cluster.

The perception of being able to cope with work is a basic requirement for work ability. This randomized controlled trial investigates whether a cognitive behavioural, work-anxiety-coping group (WAG) intervention leads to better work-coping perception than an unspecific recreational group (RG). Heterogeneous people in medical rehabilitation, who were due to return to work, were interviewed concerning their work-anxieties, and either randomly assigned to a WAG (n=85) or a RG (n=95). The participants (with an average of 50years old [range 23-64]; 51% women; 70% workers or employees, 25% academics, 5% unskilled) followed the group intervention for four or six sessions. The perceived work-coping was assessed by self-rating (Inventory for Job-Coping and Return Intention JoCoRi) after each group session. Although participants had a slight temporary decrease in work-coping after group session two (from M-1=2.47 to M-2=2.28, d(Cohen)=-.22), the WAG led to the improvement of perceived work-coping over the intervention course (from M-1=2.47 to M-6=2.65, d(Cohen)=.18). In contrast, participants from the RG reported lower work-coping after six group sessions (from M-1=2.26 to M-6=2.02, d(Cohen)=-.18). It is considered that people with work-anxieties need training in work-coping. By focusing on recreation only, this may lead to deterioration of work-coping. Indeed, intervention designers should be aware of temporary deterioration (side effects) when confronting participants with work-coping.

Twenty-four-month-old children (n =32) were presented with sets of one novel and two familiar objects, and it was found that shyer children were less likely to select a novel object as the referent of a novel label. Furthermore, not-shy children then showed evidence of retaining these novel mappings, but shy children did not. These findings suggest that shy children's aversion to novelty and to the unfamiliar context can impact on their word learning.

In this context, this paper has two related aims. The first is to show how the nature of the first phoneme influences the alignment of the ERPs. The second is to further characterize the EEG signal around the onset of articulation, both in temporal and frequency domains. Participants were asked to name aloud pictures of common objects. We applied microstate analyses and time-frequency transformations of ERPs locked to vocal onset to compare the EEG signal between voiced and unvoiced labial plosive word onset consonants. We found a delay of about 40 ms in the set of stable topographic patterns for /b/ relative to /p/ onset words. A similar shift was observed in the power increase of gamma oscillations (30-50 Hz), which had an earlier onset for /p/ trials (similar to 150 ms before vocal onset). This 40-ms shift is consistent with the length of the voiced proportion of the acoustic signal prior to the release of the closure in the vocal responses. These results demonstrate that phonetic features are an important parameter affecting response-locked ERPs, and hence that the onset of the acoustic energy may not be an optimal trigger for synchronizing the EEG activity to the response in vocal paradigms. The indexes explored in this study provide a step forward in the characterization of muscle-related artifacts in electrophysiological studies of speech and language production.

It is not known if a specific within session balance and plyometric exercise sequence provides more effective training adaptations. The objective of the present study was to investigate the effects of using a sequence of alternating pairs of exercises versus a block (series) of all balance exercises followed by a block of plyometric exercises on components of physical fitness such as muscle strength, power, speed, agility, and balance. Twenty-six male adolescent soccer players ( 13.9 +/- 0.3 years) participated in an 8-week training program that either alternated individual balance (e. g., exercises on unstable surfaces) and plyometric (e. g., jumps, hops, rebounds) exercises or performed a block of balance exercises prior to a block of plyometric exercises within each training session. Pre- and post-training measures included proxies of strength, power, agility, sprint, and balance such as countermovement jumps, isometric back and knee extension strength, standing long jump, 10 and 30-m sprints, agility, standing stork, and Y-balance tests. Both groups exhibited significant, generally large magnitude (effect sizes) training improvements for all measures with mean performance increases of approximately > 30%. There were no significant differences between the training groups over time. The results demonstrate the effectiveness of combining balance and plyometric exercises within a training session on components of physical fitness with young adolescents. The improved performance outcomes were not significantly influenced by the within session exercise sequence.

These trends are already detectable over the historic period. Hence, it is beneficial to forecast seasonal droughts well in advance so that water managers and stakeholders can prepare to mitigate deleterious impacts. We developed a new cluster-based empirical forecast method to predict precipitation anomalies in winter. This algorithm considers not only the strength but also the pattern of the precursors. We compare our algorithm with dynamic forecast models and a canonical correlation analysis-based prediction method demonstrating that our prediction method performs better in terms of time and pattern correlation in the Mediterranean and European regions.

For example, the predominantly warm Medieval Climate Anomaly (MCA) and the following cold period of the Little Ice Age (LIA) over Europe have been associated with long-lasting phases with a positive and negative NAO index. Its climatic imprint is especially pronounced in European winter seasons. However, little is known about the influence of NAO with respect to its eastern extent over the Eurasian continent. Here we present speleothem records (PC, 8180 and Sr/Ca) from the southern rim of Fergana Basin (Central Asia) revealing annually resolved past climate variations during the last millennium. The age control of the stalagmite relies on radiocarbon dating as large amounts of detrital material inhibit accurate 230Th dating. Present-day calcification of the stalagmite is most effective during spring when the cave atmosphere and elevated water supply by snow melting and high amount of spring precipitation provide optimal conditions. Seasonal precipitation variations cause changes of the stable isotope and Sr/ Ca compositions. The simultaneous changes in these geochemical proxies, however, give also evidence for fractionation processes in the cave. By disentangling both processes, we demonstrate that the amount of winter precipitation during the MCA was generally higher than during the LIA, which is in line with climatic changes linked to the NAO index but opposite to the higher mountain records of Central Asia. Several events of strongly reduced winter precipitation are observed during the LIA in Central Asia. These dry winter events can be related to phases of a strong negative NAO index and all results reveal that winter precipitation over the central Eurasian continent is tightly linked to atmospheric NAO modes by the westerly wind systems.

T1 - Wings of the butterfly BT - sunspot groups for 1826-2015 JF - Astronomy and astrophysics : an international weekly journal N2 - The spatio-temporal evolution of sunspot activity, the so-called Maunder butterfly diagram, has been continously available since 1874 using data from the Royal Greenwich Observatory, extended by SOON network data after 1976. Here we present a new extended butterfly diagram of sunspot group occurrence since 1826, using the recently digitized data from Schwabe (1826-1867) and Sporer (1866-1880). The wings of the diagram are separated using a recently developed method based on an analysis of long gaps in sunspot group occurrence in different latitude bands. We define characteristic latitudes, corresponding to the start, end, and the largest extent of the wings (the F, L, and H latitudes). The H latitudes (30 degrees-45 degrees) are highly significantly correlated with the strength of the wings (quantified by the total sum of the monthly numbers of sunspot groups). The F latitudes (20 degrees-30 degrees) depict a weak tendency, especially in the southern hemisphere, to follow the wing strength. The L latitudes (2 degrees-10 degrees) show no clear relation to the wing strength. Overall, stronger cycle wings tend to start at higher latitudes and have a greater wing extent. A strong (5-6)-cycle periodic oscillation is found in the start and end times of the wings and in the overlap and gaps between successive wings of one hemisphere. While the average wing overlap is zero in the southern hemisphere, it is two to three months in the north. A marginally significant oscillation of about ten solar cycles is found in the asymmetry of the L latitudes. The new long database of butterfly wings provides new observational constraints to solar dynamo models that discuss the spatio-temporal distribution of sunspot occurrence over the solar cycle and longer.

We assumed that a combination of individual, dyadic and contextual variables can sufficiently explain the relation between a SEN diagnosis and the likelihood of friendship. Data analysis was based on a cross-sectional sample of students (N = 1241) in second and third grade primary-school classes. To address the different levels adequately, the present study improves upon previous research in two ways: First, the sociometric data were analyzed with the p2 model, a specialized multilevel network model. Second, the study focused solely on friendships and emphasized the concept’s unique features with respect to inclusive education. Data analysis indicated that students with SEN had a decreased probability of becoming friends with their classmates compared to students without SEN. Even when individual, dyadic, and contextual variables were included into the model, the association between a SEN diagnosis and the likelihood of friendship persisted. The implications of the results are discussed with respect to their implications for inclusive teaching practice.

T1 - How dysfunctional are dysfunctional attitudes? BT - dysfunktionale Kognitionen und Depression im Kindes- und Jugendalter BT - dysfunctional cognitions and depression in children and adolescents N2 - Im kognitiven Vulnerabilitäts-Stress-Modell der Depression von A.T. Beck (1967, 1976) spielen dysfunktionale Einstellungen bei der Entstehung von Depression in Folge von erlebtem Stress eine zentrale Rolle. Diese Theorie prägt seit Jahrzehnten die ätiologische Erforschung der Depression, jedoch ist die Bedeutung dysfunktionaler Einstellungen im Prozess der Entstehung einer Depression insbesondere im Kindes- und Jugendalter nach wie vor unklar. Die vorliegende Arbeit widmet sich einigen in der bisherigen Forschung wenig behandelten Fragen. Diese betreffen u. a. die Möglichkeit nichtlinearer Effekte dysfunktionaler Einstellungen, Auswirkungen einer Stichprobenselektion, Entwicklungseffekte sowie die Spezifität etwaiger Zusammenhänge für eine depressive Symptomatik. Zur Beantwortung dieser Fragen wurden Daten von zwei Messzeitpunkten der PIER-Studie, eines großangelegten Längsschnittprojekts über Entwicklungsrisiken im Kindes- und Jugendalter, genutzt. Kinder und Jugendliche im Alter von 9 bis 18 Jahren berichteten zweimal im Abstand von ca. 20 Monaten im Selbstberichtsverfahren über ihre dysfunktionalen Einstellungen, Symptome aus verschiedenen Störungsbereichen sowie über eingetretene Lebensereignisse. Die Ergebnisse liefern Evidenz für ein Schwellenmodell, in dem dysfunktionale Einstellungen unabhängig von Alter und Geschlecht nur im höheren Ausprägungsbereich eine Wirkung als Vulnerabilitätsfaktor zeigen, während im niedrigen Ausprägungsbereich keine Zusammenhänge zur späteren Depressivität bestehen. Eine Wirkung als Vulnerabilitätsfaktor war zudem nur in der Subgruppe der anfänglich weitgehend symptomfreien Kinder und Jugendlichen zu beobachten. Das Schwellenmodell erwies sich als spezifisch für eine depressive Symptomatik, es zeigten sich jedoch auch (teilweise ebenfalls nichtlineare) Effekte dysfunktionaler Einstellungen auf die Entwicklung von Essstörungssymptomen und aggressivem Verhalten. Bei 9- bis 13-jährigen Jungen standen dysfunktionale Einstellungen zudem in Zusammenhang mit einer Tendenz, Stress in Leistungskontexten herbeizuführen. Zusammen mit den von Sahyazici-Knaak (2015) berichteten Ergebnissen aus der PIER-Studie weisen die Befunde darauf hin, dass dysfunktionale Einstellungen im Kindes- und Jugendalter – je nach betrachteter Subgruppe – Ursache, Symptom und Konsequenz der Depression darstellen können. Die in der vorliegenden Arbeit gezeigten nichtlinearen Effekte dysfunktionaler Einstellungen und die Effekte der Stichprobenselektion bieten eine zumindest teilweise Erklärung für die Heterogenität früherer Forschungsergebnisse. Insgesamt lassen sie auf komplexe – und nicht ausschließlich negative – Auswirkungen dysfunktionaler Einstellungen schließen. Für eine adäquate Beurteilung der „Dysfunktionalität“ der von A.T. Beck so betitelten Einstellungen erscheint daher eine Berücksichtigung der betrachteten Personengruppe, der absoluten Ausprägungen und der fraglichen Symptomgruppen geboten. N2 - In A. T. Beck´s prominent vulnerability-stress-model of depression (Beck 1967, 1976), dysfunctional attitudes represent the key vulnerability factor of depression. This theory has stimulated etiological research on depression for decades. However, the significance of dysfunctional attitudes for the emergence of depression in children and adolescents remains somewhat elusive. This dissertation addresses some questions unanswered by past studies, e.g. the possibility of nonlinear effects of dysfunctional attitudes, the impact of subject selection procedures, developmental effects and the specificity of dysfunctional attitudes for depressive symptomatology. These questions were examined using data from two measurement points of the PIER study, a large longitudinal project on developmental risks in childhood and adolescence. Children and adolescents aged 9 – 18 years reported dysfunctional attitudes, symptoms from various domains and stressful life events twice with a mean interval between assessments of 20 months. Results suggest a threshold model of cognitive vulnerability, in which only dysfunctional attitudes exceeding a certain threshold conferred vulnerability to depressive symptoms, while dysfunctional attitudes below the threshold were unrelated to future depressive symptoms. These effects were invariant across gender and age. Moreover, vulnerability effects of dysfunctional attitudes were observable in initially non-symptomatic participants only. The threshold model of dysfunctional attitudes turned out to be specific for the depressive symptom domain. However, relationships of different shapes were detected between dysfunctional attitudes and the development of aggressive and eating disorder symptoms. Moreover, dysfunctional attitudes in 9 – 13-year old boys predicted non-interpersonal stress generation. Along with evidence from the PIER study reported by Sahyazici-Knaak (2015), results suggest that dysfunctional attitudes in children and adolescents may represent a cause, symptom and consequence of depression, depending on the sub-population in question. The nonlinear effects of dysfunctional attitudes detected in this study might, at least in part, offer an explanation for the inconsistent results of past studies. In sum, findings of this dissertation suggest complex – and not exclusively negative - effects of dysfunctional attitudes. Thus, a judgement of the actual “dysfunctionality” of the “dysfunctional attitudes” proposed by A. T. Beck seems to require a close consideration of the absolute level of attitudes as well as the sub-population and symptom domains in question.

T1 - Widespread Increases in Iron Concentration in European and North American Freshwaters JF - Global biogeochemical cycles N2 - Recent reports of increasing iron (Fe) concentrations in freshwaters are of concern, given the fundamental role of Fe in biogeochemical processes. Still, little is known about the frequency and geographical distribution of Fe trends or about the underlying drivers. We analyzed temporal trends of Fe concentrations across 340 water bodies distributed over 10 countries in northern Europe and North America in order to gain a clearer understanding of where, to what extent, and why Fe concentrations are on the rise. We found that Fe concentrations have significantly increased in 28% of sites, and decreased in 4%, with most positive trends located in northern Europe. Regions with rising Fe concentrations tend to coincide with those with organic carbon (OC) increases. Fe and OC increases may not be directly mechanistically linked, but may nevertheless be responding to common regional-scale drivers such as declining sulfur deposition or hydrological changes. A role of hydrological factors was supported by covarying trends in Fe and dissolved silica, as these elements tend to stem from similar soil depths. A positive relationship between Fe increases and conifer cover suggests that changing land use and expanded forestry could have contributed to enhanced Fe export, although increases were also observed in nonforested areas. We conclude that the phenomenon of increasing Fe concentrations is widespread, especially in northern Europe, with potentially significant implications for wider ecosystem biogeochemistry, and for the current browning of freshwaters.

However, the success of SNS initiatives is largely dependent on sustainable user participation. In this study, we argue that the continuance intentions of users may be gender sensitive. To theorize and investigate gender differences in the determinants of continuance intentions, this study draws on the expectation-confirmation model, the uses and gratification theory, as well as the self-construal theory and its extensions. Our survey of 488 users shows that while both men and women are motivated by the ability to self enhance, there are some gender differences. Specifically, while women are mainly driven by relational uses, such as maintaining close ties and getting access to social information on close and distant networks, men base their continuance intentions on their ability to gain information of a general nature. Our research makes several contributions to the discourse in strategic information systems literature concerning the use of social media by individuals and organizations. Theoretically, it expands the understanding of the phenomenon of continuance intentions and specifically the role of the gender differences in its determinants. On a practical level, it delivers insights for SNS providers and marketers into how satisfaction and continuance intentions of male and female SNS users can be differentially promoted. Furthermore, as organizations increasingly rely on corporate social networks to foster collaboration and innovation, our insights deliver initial recommendations on how organizational social media initiatives can be supported with regard to gender-based differences.

This was so far not considered in the development of PTH assays used in current clinical practice. Patients with advanced CKD are subject to oxidative stress, and plasma proteins (including PTH) are targets for oxidants. In patients with CKD, a considerable but variable fraction (about 70 to 90%) of measured PTH appears to be oxidized. Oxidized PTH (oxPTH) does not interact with the PTH receptor resulting in loss of biological activity. Currently used intact PTH (iPTH) assays detect both oxidized and non-oxPTH (n-oxPTH). Clinical studies demonstrated that bioactive, n-oxPTH, but not iPTH nor oxPTH, is associated with mortality in CKD patients.

However, in many estuaries, extensive embankments, artificial bank protection, river dredging and agriculture threaten tidal marshes. In this study we analysed the processes underlying the spatio-temporal patterns of tidal marsh vegetation in the Elbe estuary and quantified the influence of specific habitat factors by developing and applying the process-based dynamic habitat-macrophyte model HaMac in a pattern-oriented way. In order to develop and parameterise the model, we measured a wide range of biotic and abiotic parameters in two study sites in the Elbe estuary and compared observed and simulated patterns. The final model is able to reproduce the general patterns of vegetation zonation, development and growth and thus helps to understand the underlying processes. By considering the vegetative reproduction of marsh plants as well as abiotic influence factors and intraspecific competition, HaMac allowed to systematically analyse the significance of factors and processes for the dynamic of tidal marsh vegetation. Our results show that rhizome growth is the most important process and that flow velocity, inundation height and duration as well as intraspecific competition are the most important habitat factors for explaining spatio-temporal dynamics of brackish marshes. Future applications of HaMac could support the sustainable development and stabilisation of shore zones and thus contribute to the promotion and planning of ecosystem -based shoreline protection measures.

T1 - Where does the community start, and where does it end? BT - including the seed bank to reassess forest herb layer responses to the environment JF - Journal of vegetation science N2 - QuestionBelow-ground processes are key determinants of above-ground plant population and community dynamics. Still, our understanding of how environmental drivers shape plant communities is mostly based on above-ground diversity patterns, bypassing below-ground plant diversity stored in seed banks. As seed banks may shape above-ground plant communities, we question whether concurrently analysing the above- and below-ground species assemblages may potentially enhance our understanding of community responses to environmental variation. LocationTemperate deciduous forests along a 2000km latitudinal gradient in NW Europe. MethodsHerb layer, seed bank and local environmental data including soil pH, canopy cover, forest cover continuity and time since last canopy disturbance were collected in 129 temperate deciduous forest plots. We quantified herb layer and seed bank diversity per plot and evaluated how environmental variation structured community diversity in the herb layer, seed bank and the combined herb layer-seed bank community. ResultsSeed banks consistently held more plant species than the herb layer. How local plot diversity was partitioned across the herb layer and seed bank was mediated by environmental variation in drivers serving as proxies of light availability. The herb layer and seed bank contained an ever smaller and ever larger share of local diversity, respectively, as both canopy cover and time since last canopy disturbance decreased. Species richness and -diversity of the combined herb layer-seed bank community responded distinctly differently compared to the separate assemblages in response to environmental variation in, e.g. forest cover continuity and canopy cover. ConclusionsThe seed bank is a below-ground diversity reservoir of the herbaceous forest community, which interacts with the herb layer, although constrained by environmental variation in e.g. light availability. The herb layer and seed bank co-exist as a single community by means of the so-called storage effect, resulting in distinct responses to environmental variation not necessarily recorded in the individual herb layer or seed bank assemblages. Thus, concurrently analysing above- and below-ground diversity will improve our ecological understanding of how understorey plant communities respond to environmental variation.

We investigate whether this leads readers to look directly at a word but not pay attention to it. We used a gaze-contingent boundary paradigm to dissociate parafoveal and foveal information (e.g., the word phone changed to scarf once the reader's eyes moved to it) and asked questions about the sentence to determine which one the reader encoded. When the word was skipped or fixated only briefly (i.e., up to 100 ms) readers were more likely to report reading the parafoveal than the fixated word, suggesting that there are cases in which readers look directly at a word but their minds ignore it, leading to the illusion of reading something they did not fixate.

This type of approach has recently been developed as an alternative to top-down approaches for the assessment of climate change impacts. A major limitation of this approach is the underrepresentation of changes in the temporal structure of the climate input data (i.e., the seasonal and day-to-day variability) since this is not altered by the perturbation. This paper presents a framework that aims to examine this limitation by perturbing both observed and projected climate data time series for a future period, which both serve as input into a hydrological model (the HBV model). The resulting multiple response surfaces are compared at a common domain, the standardized runoff response surface (SRRS). We apply this approach in a case study catchment in Norway to (i) analyze possible changes in mean and extreme runoff and (ii) quantify the influence of changes in the temporal structure represented by 17 different climate input sets using linear mixed-effect models. Results suggest that climate change induced increases in mean and peak flow runoff and only small changes in low flow. They further suggest that the effect of the different temporal structures of the climate input data considerably affects low flows and floods (at least 21% influence), while it is negligible for mean runoff.

Accordingly, this article demonstrates how Lewin’s concepts can still be of use in tackling current issues (i.e. the need to raise energy-saving behaviours within organizations). In order to revive Lewin’s concepts, we combine his approaches on organization change with Motivational Interviewing (MI), a facilitation approach that fits well with his democratic and participatory mind-set. After a theoretical consideration of how Lewin’s ideas could be accompanied by MI principles, we outline a practical concept for raising the level of employees’ energy-saving behaviours to a higher standard. The usefulness of our concept is highlighted on the basis of qualitative (a force field analysis) and quantitative (an increase of energy-saving norms and – behaviours) data. Lewin’s legacy for current organization development, and the theoretical as well as practical implications for how his ideas could be applied through a combination with MI practices, are discussed.

The two-step task allows distinguishing between these mechanisms by computationally modeling goal-directed and habitual behavior as model-based and model-free control. In addicted patients, decision making may also strongly depend upon drug-associated expectations. Therefore, we investigated model-based versus model-free decision making and its neural correlates as well as alcohol expectancies in alcohol-dependent patients and healthy controls and assessed treatment outcome in patients. METHODS: Ninety detoxified, medication-free, alcohol-dependent patients and 96 age-and gender-matched control subjects underwent functional magnetic resonance imaging during the two-step task. Alcohol expectancies were measured with the Alcohol Expectancy Questionnaire. Over a follow-up period of 48 weeks, 37 patients remained abstinent and 53 patients relapsed as indicated by the Alcohol Timeline Followback method. RESULTS: Patients who relapsed displayed reduced medial prefrontal cortex activation during model-based decision making. Furthermore, high alcohol expectancies were associated with low model-based control in relapsers, while the opposite was observed in abstainers and healthy control subjects. However, reduced model-based control per se was not associated with subsequent relapse. CONCLUSIONS: These findings suggest that poor treatment outcome in alcohol dependence does not simply result from a shift from model-based to model-free control but is instead dependent on the interaction between high drug expectancies and low model-based decision making. Reduced model-based medial prefrontal cortex signatures in those who relapse point to a neural correlate of relapse risk. These observations suggest that therapeutic interventions should target subjective alcohol expectancies.

BT - insights from a survey among flood-affected residents in German JF - Regional environmental change N2 - The number of people exposed to natural hazards has grown steadily over recent decades, mainly due to increasing exposure in hazard-prone areas. In the future, climate change could further enhance this trend. Still, empirical and comprehensive insights into individual recovery from natural hazards are largely lacking, hampering efforts to increase societal resilience. Drawing from a sample of 710 residents affected by flooding across Germany in June 2013, we empirically explore a wide range of variables possibly influencing self-reported recovery, including flood-event characteristics, the circumstances of the recovery process, socio-economic characteristics, and psychological factors, using multivariate statistics. We found that the amount of damage and other flood-event characteristics such as inundation depth are less important than socio-economic characteristics (e.g., sex or health status) and psychological factors (e.g., risk aversion and emotions). Our results indicate that uniform recovery efforts focusing on areas that were the most affected in terms of physical damage are insufficient to account for the heterogeneity in individual recovery results. To increase societal resilience, aid and recovery efforts should better address the long-term psychological effects of floods.

JF - Journal of hydrology N2 - Flood events can be expressed by a variety of characteristics such as flood magnitude and extent, event duration or incurred loss. Flood estimation and management may benefit from understanding how the different flood characteristics relate to the hydrological catchment conditions preceding the event and to the meteorological conditions throughout the event. In this study, we therefore propose a methodology to investigate the hydro-meteorological controls on different flood characteristics, based on the simulation of the complete flood risk chain from the flood triggering precipitation event, through runoff generation in the catchment, flood routing and possible inundation in the river system and floodplains to flood loss. Conditional cumulative distribution functions and regression tree analysis delineate the seasonal varying flood processes and indicate that the effect of the hydrological pre-conditions, i.e. soil moisture patterns, and of the meteorological conditions, i.e. weather patterns, depends on the considered flood characteristic. The methodology is exemplified for the Elbe catchment. In this catchment, the length of the build-up period, the event duration and the number of gauges undergoing at least a 10-year flood are governed by weather patterns. The affected length and the number of gauges undergoing at least a 2-year flood are however governed by soil moisture patterns. In case of flood severity and loss, the controlling factor is less pronounced. Severity is slightly governed by soil moisture patterns whereas loss is slightly governed by weather patterns. The study highlights that flood magnitude and extent arise from different flood generation processes and concludes that soil moisture patterns as well as weather patterns are not only beneficial to inform on possible flood occurrence but also on the involved flood processes and resulting flood characteristics.

On the basis of selected writings of Georg Forster, Alexander von Humboldt, and Adelbert von Chamisso, the author highlights the increasing speed with which knowledge, especially in the experiential sciences, is produced and disseminated following the routes of ever-widening trade speeded along by globalization. The notion of ‘vectopia’ stands for the connection of utopia and uchronia in space and time in such a way that the experience of the world, expanded worldwide, contains within it a Weiter-Leben, a ‘living-further’ that is to be understood first in a spatial, and not yet temporal, sense, of what Forster called Erfahrungswissen, or ‘experiential knowledge.’ Vectopia, as elaborated here, has a material dimension that relates to the physical person, the body, the experience of the world that cannot occur without the constant changing of place, without a journeying that is again and again recommenced. Vectopia develops the projection of a life not from space or from time alone, but by their combination. Vectopia is more than a concept, it is a thought-figure: it is vitally connected to life, and thus a life-figure. It opens itself to a type of knowledge that stands almost at the threshold of a further life, indeed, of a Weiterleben that, opening itself to a ‘living-onward,’ resides beyond space, time, and movement.

The influence of body image concern on eating concern was also investigated. Method: In a prospective study, 675 male and female adolescents aged 12–16 were assessed using self-report questionnaires on weight, shape, muscularity, and eating concerns. Height and weight measurements were taken by trained personnel. Data were analyzed using structural equation modeling. Results: Analyses of latent means revealed more pronounced weight/shape concern in females than males and more pronounced muscularity concern in males than females. Weight/shape concern increased in females over time, whereas muscularity concern remained stable in both genders. Baseline levels of weight/shape concern could be predicted by age and weight status in females and by weight status in males. The only predictor of change in weight/shape concern was weight status in males. Baseline levels of muscularity concern could be predicted by age in females and by weight status in males. Similar effects were found for changes in muscularity concern in both genders. Increases in weight/shape and muscularity concern were associated with more pronounced eating concern. Discussion: The results confirm gender differences in distinctive facets of body image concern and its prediction. The relevance of increase in body image concern in adolescents is underlined by its association with eating concern in both genders. Further explanatory variables for change in body dissatisfaction should be examined in future studies.

Ausgangspunkt dafür sind Messdaten und Modellsimulationen für den Zeitraum der N-ICE2015 Expedition, die von Anfang Januar bis Ende Juni 2015 im arktischen Nordatlantiksektor stattgefunden hat. Anhand von Radiosondenmessungen lassen sich Auswirkungen von synoptischen Zyklonen am deutlichsten im Winter erkennen, da sie durch die Advektion warmer und feuchter Luftmassen in die Arktis den Zustand der Atmosphäre von einem strahlungs-klaren in einen strahlungs-opaken ändern. Obwohl dieser scharfe Kontrast nur im Winter existiert, zeigt die Analyse, dass der integrierte Wasserdampf als Indikator für die Advektion von Luftmassen aus niedrigen Breiten in die Arktis auch im Frühjahr geeignet ist. Neben der Advektion von Luftmassen wird der Einfluss der Zyklonen auf die statische Stabilität charakterisiert. Beim Vergleich der N-ICE2015 Beobachtungen mit der SHEBA Kampagne (1997/1998), die über dickerem Eis stattfand, finden sich trotz der unterschiedlichen Meereisregime Ähnlichkeiten in der statischen Stabilität der Atmosphäre. Die beobachteten Differenzen in der Stabilität lassen sich auf Unterschiede in der synoptischen Aktivität zurückführen. Dies lässt vermuten, dass die dünnere Eisdecke auf saisonalen Zeitskalen nur einen geringen Einfluss auf die thermodynamische Struktur der arktischen Troposphäre besitzt, solange eine dicke Schneeschicht sie bedeckt. Ein weiterer Vergleich mit den parallel zur N-ICE2015 Kampagne gestarteten Radiosonden der AWIPEV Station in Ny-Åesund, Spitzbergen, macht deutlich, dass die synoptischen Zyklonen oberhalb der Orographie auf saisonalen Zeitskalen das Wettergeschehen bestimmen. Des Weiteren werden für Februar 2015 die Auswirkungen von in der Vertikalen variiertem Nudging auf die Entwicklung der Zyklonen am Beispiel des hydrostatischen regionalen Klimamodells HIRHAM5 untersucht. Es zeigt sich, dass die Unterschiede zwischen den acht Modellsimulationen mit abnehmender Anzahl der genudgten Level zunehmen. Die größten Differenzen resultieren vornehmlich aus dem zeitlichen Versatz der Entwicklung synoptischer Zyklonen. Zur Korrektur des Zeitversatzes der Zykloneninitiierung genügt es bereits, Nudging in den unterstem 250 m der Troposphäre anzuwenden. Daneben findet sich zwischen den genudgten HIRHAM5-Simulation und den in situ Messungen der gleiche positive Temperaturbias, den auch ERA-Interim besitzt. Das freie HIRHAM hingegen reproduziert das positive Ende der N-ICE2015 Temperaturverteilung gut, besitzt aber einen starken negativen Bias, der sehr wahrscheinlich aus einer Unterschätzung des Feuchtegehalts resultiert. An Beispiel einer Zyklone wird gezeigt, dass Nudging Einfluss auf die Lage der Höhentiefs besitzt, die ihrerseits die Zyklonenentwicklung am Boden beeinflussen. Im Weiteren wird mittels eines für kleine Ensemblegrößen geeigneten Varianzmaßes eine statistische Einschätzung der Wirkung des Nudgings auf die Vertikale getroffen. Es wird festgestellt, dass die Ähnlichkeit der Modellsimulationen in der unteren Troposphäre generell höher ist als darüber und in 500 hPa ein lokales Minimum besitzt. Im letzten Teil der Analyse wird die Wechselwirkung der oberen und unteren Stratosphäre anhand zuvor betrachteter Zyklonen mit Daten der ERA-Interim Reanalyse untersucht. Lage und Ausrichtung des Polarwirbels erzeugten ab Anfang Februar 2015 eine ungewöhnlich große Meridionalkomponente des Tropopausenjets, die Zugbahnen in die zentrale Arktis begünstigte. Am Beispiel einer Zyklone wird die Übereinstimmung der synoptischen Entwicklung mit den theoretischen Annahmen über den abwärts gerichteten Einfluss der Stratosphäre auf die Troposphäre hervorgehoben. Dabei spielt die nicht-lineare Wechselwirkung zwischen der Orographie Grönlands, einer Intrusion stratosphärischer Luft in die Troposphäre sowie einer in Richtung Arktis propagierender Rossby-Welle eine tragende Rolle. Als Indikator dieser Wechselwirkung werden horizontale Signaturen aus abwechselnd aufsteigender und absinkender Luft innerhalb der Troposphäre identifiziert. N2 - The Arctic warms faster than the rest of the earth. The causes and effects of this arctic amplification are manifested in the arctic atmosphere, especially in the atmospheric boundary layer, which plays a key role in the exchange processes of the atmosphere, ocean and sea ice. This work highlights the importance of synoptic cyclones in the Arctic North Atlantic region. For this purpose, the influence of synoptic cyclones on the Arctic boundary layer as well as their interactions with different regions within the Arctic atmosphere on local to supraregional scales is investigated. The starting point for this are measurement data and model simulations for the period of the NICE2015 expedition, which took place in the Arctic North Atlantic region from early January to late June 2015. On the basis of radiosonde measurements, the effects of synoptic cyclones are most noticeable in the winter because, by the advection of warm and humid air masses into the Arctic, the condition of the atmosphere changes from a radiative clear to opaquely cloudy. Although this sharp contrast only exists in winter, the analysis shows that integrated water vapor is an indicator for the advection of air masses from low latitudes into the Arctic even in the spring. In addition to the advection of air masses, the influence of cyclones on static stability is characterized. Comparing the N-ICE2015 observations with the SHEBA campaign (1997/1998), which took place over thicker ice, similarities are found in the static stability of the atmosphere despite the different sea ice regimes. The observed differences in stability can be attributed to differences in synoptic activity. A further comparison with the radiosondes of the AWIPEV station in Ny-Åesund, Spitzbergen, which were launched parallel to the N-ICE2015 campaign, shows that synoptic cyclones determine the course of the winter months. In addition, the effects of vertically-varying nudging on the development of cyclones is examined for February 2015 using the hydrostatic regional climate model HIRHAM5. It is shown that the differences between the eight model simulations are increasing with decreasing number of nudged levels. The greatest differences are mainly due to the temporal offset of the development of synoptic cyclones. To correct the time offset of the cyclone initiation, it is sufficient to use nudging in the lowest troposphere. The free HIRHAM reproduces the positive end of the N-ICE2015 temperature distribution well, but has a strong negative bias which most likely results from an under-estimation of the moisture content. An example of a cyclone shows that nudging has an influence on the position of the high altitude lows, which in turn influences cyclone development on the ground. Furthermore, a statistical estimate of the effect of nudging on the vertical is made by means of a variance measure suitable for small ensemble sizes. It is found that the similarity of model simulations in the lower troposphere is generally higher than above and has a local minimum in 500 hPa. In the last part of the analysis, the interaction of the upper troposphere and the lower stratosphere is investigated with data from the ERA interim reanalysis using previously examined cyclones. The position and orientation of the polar vortex produced an unusually large meridional component of the tropopause jets, which favored passage of low pressure systems into the central Arctic from the beginning of February 2015 onwards. Using a cyclone as an example, the synoptic development is compared with the theoretical assumptions about the downward impact of the stratosphere on the troposphere. The non-linear interaction between Greenland’s orography, an intrusion of stratospheric air into the troposphere, and a Rossby wave propagating in the direction of the Arctic play a key role in the selected time frame. As an indicator of this interaction, horizontal signatures are identified from alternately ascending and descending air within the troposphere.

Three cellulose derivatives, a polyanion, a polycation, and a polyzwitterion were used as additives. Scanning electron microscopy, X-ray diffraction, IR and Raman spectroscopy show that, depending on the composition of the starting solution, hydroxyapatite or brushite precipitates form. Infrared and Raman spectroscopy also show that significant amounts of nitrate ions are incorporated in the precipitates. Energy dispersive X-ray spectroscopy shows that the Ca/P ratio varies throughout the samples and resembles that of other bioinspired calcium phosphate hybrid materials. Elemental analysis shows that the carbon (i.e., polymer) contents reach 10% in some samples, clearly illustrating the formation of a true hybrid material. Overall, the data indicate that a higher polymer concentration in the reaction mixture favors the formation of polymer-enriched materials, while lower polymer concentrations or high precursor concentrations favor the formation of products that are closely related to the control samples precipitated in the absence of polymer. The results thus highlight the potential of (water-soluble) cellulose derivatives for the synthesis and design of bioinspired and bio-based hybrid materials.

Solute and heat exchange across this interface is driven by the advection of water. Characterizing the flow conditions in the streambed is challenging as flow patterns are often complex and multidimensional, driven by surface hydraulic gradients and groundwater discharge. This thesis presents the results of an integrated approach of studies, ranging from the acquisition of field data, the development of analytical and numerical approaches to analyse vertical temperature profiles to the detailed, fully-integrated 3D numerical modelling of water and heat flux at the reach scale. All techniques were applied in order to characterize exchange flux between stream and groundwater, hyporheic flow paths and temperature patterns. The study was conducted at a reach-scale section of the lowland Selke River, characterized by distinctive pool riffle sequences and fluvial islands and gravel bars. Continuous time series of hydraulic heads and temperatures were measured at different depths in the river bank, the hyporheic zone and within the river. The analyses of the measured diurnal temperature variation in riverbed sediments provided detailed information about the exchange flux between river and groundwater. Beyond the one-dimensional vertical water flow in the riverbed sediment, hyporheic and parafluvial flow patterns were identified. Subsurface flow direction and magnitude around fluvial islands and gravel bars at the study site strongly depended on the position around the geomorphological structures and on the river stage. Horizontal water flux in the streambed substantially impacted temperature patterns in the streambed. At locations with substantial horizontal fluxes the penetration depths of daily temperature fluctuations was reduced in comparison to purely vertical exchange conditions. The calibrated and validated 3D fully-integrated model of reach-scale water and heat fluxes across the river-groundwater interface was able to accurately represent the real system. The magnitude and variations of the simulated temperatures matched the observed ones, with an average mean absolute error of 0.7 °C and an average Nash Sutcliffe Efficiency of 0.87. The simulation results showed that the water and heat exchange at the surface water-groundwater interface is highly variable in space and time with zones of daily temperature oscillations penetrating deep into the sediment and spots of daily constant temperature following the average groundwater temperature. The average hyporheic flow path temperature was found to strongly correlate with the flow path residence time (flow path length) and the temperature gradient between river and groundwater. Despite the complexity of these processes, the simulation results allowed the derivation of a general empirical relationship between the hyporheic residence times and temperature patterns. The presented results improve our understanding of the complex spatial and temporal dynamics of water flux and thermal processes within the shallow streambed. Understanding these links provides a general basis from which to assess hyporheic temperature conditions in river reaches. N2 - Die Interaktion zwischen Oberflächenwasser und Grundwasser hat einen entscheidenden Einfluss auf die Wasserqualität und die ökologische Beschaffenheit von Seen, Flüssen und aquatischen Ökosystemen. Der Austausch von Wärme und gelösten Substanzen zwischen diesen beiden Kompartimenten ist maßgeblich durch die Austauschraten und die Strömungsrichtung des Wassers beeinflusst. Somit ist die Charakterisierung dieser beiden Größen in dem Übergangsbereich zwischen Oberflächenwasser und Grundwasser von besonderer Bedeutung. Diese Arbeit präsentiert die Entwicklung und Anwendung von Methoden zur Untersuchung der zeitlichen und räumlichen Dynamik des Wasser- und Wärmeflusses an der Schnittstelle zwischen Oberflächenwasser und Grundwasser. Die Arbeit besteht im Wesentlichen aus zwei Schwerpunkten. Der erste Schwerpunkt beinhaltet die Entwicklung und Bewertung von analytischen und numerischen Methoden zur Bestimmung der horizontalen Strömungsrichtung und Austauschraten unter Verwendung von kontinuierlich gemessenen Temperaturzeitreihen entlang vertikaler Profile im gesättigten Sediment. Flussbetttemperaturen können relativ einfach und kostengünstig entlang eines Flussabschnittes in verschiedenen Tiefen und unterschiedlichsten Flussbettsedimenten (organisch, sandig bis grob kiesig) gemessen werden. Die Hauptverwendung solcher Temperaturprofile ist bisher auf die analytische Quantifizierung vertikaler Austauschraten limitiert. Im Rahmen dieser Arbeit wurde ein Ansatz entwickelt, der eine punktuelle Ermittlung der horizontalen Strömungs-komponente, basierend auf der Veränderung der täglichen Temperaturamplitude mit zunehmender Tiefe, ermöglicht. Weiterhin wurde ein inverser, numerischer Ansatz entwickelt, der die ein-dimensionale Wärmetransportgleichung numerisch löst und mittels inverser Optimierungsalgorithmen die simulierten Temperaturen bestmöglich an die gemessenen Flussbetttemperaturen anpasst. Diese Methode ermöglicht die automatische, zeitlich variable Quantifizierung vertikaler Austauschraten an der Schnittstelle zwischen Oberflächenwasser und Grundwasser sowie eine einfache Unsicherheitsbetrachtung aufgrund der zugrunde liegenden Parameterunsicherheiten. Der zweite Schwerpunkt der Arbeit liegt auf der Anwendung der entwickelten Methoden und der Erstellung eines dreidimensionalen Simulationsmodelles entlang eines Flussabschnittes der Selke. Numerische Strömungs- und Stofftransportmodelle ermöglichen die gekoppelte Simulation von Fließprozessen im offenen Gerinne und im darunter liegenden porösen Medium. Die Parametrisierung des Modells erfolgte anhand empirischer Daten die im Untersuchungsgebiet detailliert erhoben wurden. Die Simulationsergebnisse zeigten zum einen gebietsspezifische Gegebenheiten auf, ermöglichten darüber hinaus jedoch auch die Beschreibung allgemeiner Muster und Zusammenhänge welche die Wasserfluss- und Wärmetransportprozesse an der Schnittstelle zwischen Oberflächenwasser und Grundwasser beeinflussen. So zeigten die Ergebnisse dieser Arbeit, dass maßgeblich die natürlich vorhandenen Flussbettstrukturen die Austauschraten und die Strömungsrichtung zwischen Oberflächenwasser und Grundwasser beeinflussen und somit den hyporheischen Austausch bestimmen. Wichtige Einflussfaktoren auf die untersuchten Austauschprozesse waren die Lage im Gerinne relativ zur Flussbettstruktur und der vorherrschende Wasserstand (Abfluss). Bedingt durch den Wasser- und Wärmeaustausch prägten sich im Untersuchungsgebiet Bereiche aus in denen die täglichen Temperaturschwingungen tief in das Sediment eindringen (Anstrombereich der Flussbettstrukturen), als auch Bereiche in denen relativ konstante Temperaturen, nahe der Grundwassertemperatur, vorherrschten. Die durchschnittliche Temperatur in der hyporheischen Zone wurde durch die saisonalen Temperaturschwankungen im Oberflächenwasser dominiert, wobei die Temperaturen entlang einzelner Fließpfade stark von der Verweilzeit des Oberflächen- oder Grundwassers im gesättigten Sediment und dem Temperaturgradienten zwischen Fluss und Grundwasser abhängig waren. Trotz der Komplexität dieser Zusammenhänge, ermöglichten die Simulationsergebnisse die Ableitung einer allgemeinen empirischen Beziehung zwischen den hyporheischen Verweilzeiten und Temperaturmustern. Sowohl die Verweilzeiten als auch die Temperatur im gesättigten Sediment haben einen entscheiden Einfluss auf biogeochemische Prozesse in dem Übergangsbereich zwischen Oberflächenwasser und Grundwasser und sind somit von besonderer Bedeutung für die Wasserqualität von Seen, Flüssen und aquatischen Ökosystemen.

T1 - Vulnerability of European freshwater catchments to climate change JF - Global change biology N2 - Climate change is expected to exacerbate the current threats to freshwater ecosystems, yet multifaceted studies on the potential impacts of climate change on freshwater biodiversity at scales that inform management planning are lacking. The aim of this study was to fill this void through the development of a novel framework for assessing climate change vulnerability tailored to freshwater ecosystems. The three dimensions of climate change vulnerability are as follows: (i) exposure to climate change, (ii) sensitivity to altered environmental conditions and (iii) resilience potential. Our vulnerability framework includes 1685 freshwater species of plants, fishes, molluscs, odonates, amphibians, crayfish and turtles alongside key features within and between catchments, such as topography and connectivity. Several methodologies were used to combine these dimensions across a variety of future climate change models and scenarios. The resulting indices were overlaid to assess the vulnerability of European freshwater ecosystems at the catchment scale (18 783 catchments). The Balkan Lakes Ohrid and Prespa and Mediterranean islands emerge as most vulnerable to climate change. For the 2030s, we showed a consensus among the applied methods whereby up to 573 lake and river catchments are highly vulnerable to climate change. The anthropogenic disruption of hydrological habitat connectivity by dams is the major factor reducing climate change resilience. A gap analysis demonstrated that the current European protected area network covers <25% of the most vulnerable catchments. Practical steps need to be taken to ensure the persistence of freshwater biodiversity under climate change. Priority should be placed on enhancing stakeholder cooperation at the major basin scale towards preventing further degradation of freshwater ecosystems and maintaining connectivity among catchments. The catchments identified as most vulnerable to climate change provide preliminary targets for development of climate change conservation management and mitigation strategies.

The SCPs used here are time-averaged shear-wave velocity in the top 30 m (VS30), the topographical slope (slope), the fundamental resonance frequency (f0) and the depth beyond which Vs exceeds 800 m/s (H800). We considered first the performance of each SCP taken alone and then the combined performance of the 6 SCP pairs [VS30–f0], [VS30–H800], [f0–slope], [H800–slope], [VS30–slope] and [f0–H800]. This analysis is performed using a neural network approach including a random effect applied on a KiK-net subset for derivation of ground-motion prediction equations setting the relationship between various ground-motion parameters such as peak ground acceleration, peak ground velocity and pseudo-spectral acceleration PSA (T), and Mw, RJB, focal depth and SCPs. While the choice of SCP is found to have almost no impact on the median groundmotion prediction, it does impact the level of aleatory uncertainty. VS30 is found to perform the best of single proxies at short periods (T < 0.6 s), while f0 and H800 perform better at longer periods; considering SCP pairs leads to significant improvements, with particular emphasis on [VS30–H800] and [f0–slope] pairs. The results also indicate significant nonlinearity on the site terms for soft sites and that the most relevant loading parameter for characterising nonlinear site response is the “stiff” spectral ordinate at the considered period.
