With less than two decades of activity, research on melt inclusions (MI) in crystals from rocks that have undergone crustal anatexis - migmatites and granulites - is a recent addition to crustal petrology and geochemistry. Studies on this subject started with glassy inclusions in anatectic crustal enclaves in lavas, and then progressed to regionally metamorphosed and partially melted crustal rocks, where melt inclusions are normally crystallized into a cryptocrystalline aggregate (nanogranitoid).
Since the first paper on melt inclusions in the granulites of the Kerala Khondalite Belt in 2009, reported and studied occurrences are already a few tens. Melt inclusions in migmatites and granulites show many analogies with their more common and long studied counterparts in igneous rocks, but also display very important differences and peculiarities, which are the subject of this review. Microstructurally, melt inclusions in anatectic rocks are small, commonly 10 mu m in diameter, and their main mineral host is peritectic garnet, although several other hosts have been observed. Inclusion contents vary from glass in enclaves that were cooled very rapidly from supersolidus temperatures, to completely crystallized material in slowly cooled regional migmatites. The chemical composition of the inclusions can be analyzed combining several techniques (SEM, EMP, NanoSIMS, LA-ICP-MS), but in the case of crystallized inclusions the experimental remelting under confining pressure in a piston cylinder is a prerequisite. The melt is generally granitic and peraluminous, although granodioritic to trondhjemitic compositions have also been found.
Being mostly primary in origin, inclusions attest for the growth of their peritectic host in the presence of melt. As a consequence, the inclusions have the unique ability of preserving information on the composition of primary anatectic crustal melts, before they undergo any of the common following changes in their way to produce crustal magmas. For these peculiar features, melt inclusions in migmatites and granulites, largely overlooked so far, have the potential to become a fundamental tool for the study of crustal melting, crustal differentiation, and even the generation of the continental crust.

This international curricular review provides a structured overview of the particle physics content in 27 state, national, and international high-school physics curricula. The review was based on a coding manual that included 60 concepts that were identified as relevant for high-school particle physics education.
Two types of curricula were reviewed, namely curricula with a dedicated particle physics chapter and curricula without a dedicated particle physics chapter.
The results of the curricular review show that particle physics concepts are explicitly or implicitly present in all reviewed curricula.
However, the number of particle physics concepts that are featured in a curriculum varies greatly across the reviewed curricula. We identified core particle physics concepts that can be found in most curricula. Here, elementary particles, fundamental interactions, and charges were identified as explicit particle physics concepts that are featured in more than half of the reviewed curricula either as content or context. Indeed, theoretical particle physics concepts are more prominent in high-school physics curricula than experimental particle physics concepts.
Overall, this international curricular review provides the basis for future curricular development with respect to particle physics and suggests an increased inclusion of experimental particle physics concepts in high-school physics curricula.
Eye movement data have proven to be very useful for investigating human sentence processing. Eyetracking research has addressed a wide range of questions, such as recovery mechanisms following garden-pathing, the timing of processes driving comprehension, the role of anticipation and expectation in parsing, the role of semantic, pragmatic, and prosodic information, and so on. However, there are some limitations regarding the inferences that can be made on the basis of eye movements. One relates to the nontrivial interaction between parsing and the eye movement control system which complicates the interpretation of eye movement data. Detailed computational models that integrate parsing with eye movement control theories have the potential to unpack the complexity of eye movement data and can therefore aid in the interpretation of eye movements. Another limitation is the difficulty of capturing spatiotemporal patterns in eye movements using the traditional word-based eyetracking measures. Recent research has demonstrated the relevance of these patterns and has shown how they can be analyzed. In this review, we focus on reading, and present examples demonstrating how eye movement data reveal what events unfold when the parser runs into difficulty, and how the parsing system interacts with eye movement control.

Over the last two decades, macroecology the analysis of large-scale, multi-species ecological patterns and processes has established itself as a major line of biological research. Analyses of statistical links between environmental variables and biotic responses have long and successfully been employed as a main approach, but new developments are due to be utilized. Scanning the horizon of macroecology, we identified four challenges that will probably play a major role in the future. We support our claims by examples and bibliographic analyses. 1) Integrating the past into macroecological analyses, e.g. by using paleontological or phylogenetic information or by applying methods from historical biogeography, will sharpen our understanding of the underlying reasons for contemporary patterns. 2) Explicit consideration of the local processes that lead to the observed larger-scale patterns is necessary to understand the fine-grain variability found in nature, and will enable better prediction of future patterns (e.g. under environmental change conditions). 3) Macroecology is dependent on large-scale, high quality data from a broad spectrum of taxa and regions. More available data sources need to be tapped and new, small-grain large-extent data need to be collected. 4) Although macroecology already lead to mainstreaming cutting-edge statistical analysis techniques, we find that more sophisticated methods are needed to account for the biases inherent to sampling at large scale. Bayesian methods may be particularly suitable to address these challenges. To continue the vigorous development of the macroecological research agenda, it is time to address these challenges and to avoid becoming too complacent with current achievements.
Spatial numerical associations (SNAs) are prevalent yet their origin is poorly understood. We first consider the possible prime role of reading habits in shaping SNAs and list three observations that argue against a prominent influence of this role: (1) directional reading habits for numbers may conflict with those for non-numerical symbols, (2) short-term experimental manipulations can overrule the impact of decades of reading experience, (3) SNAs predate the acquisition of reading. As a promising alternative, we discuss behavioral, neuroscientific, and neuropsychological evidence in support of finger counting as the most likely initial determinant of SNAs. Implications of this "manumerical cognition" stance for the distinction between grounded, embodied, and situated cognition are discussed.

Zooplankton carcasses are ubiquitous in marine and freshwater systems, implicating the importance of non-predatory mortality, but both are often overlooked in ecological studies compared with predatory mortality. The development of several microscopic methods allows the distinction between live and dead zooplankton in field samples, and the reported percentages of dead zooplankton average 11.6 (minimum) to 59.8 (maximum) in marine environments, and 7.4 (minimum) to 47.6 (maximum) in fresh and inland waters. Common causes of non-predatory mortality among zooplankton include senescence, temperature change, physical and chemical stresses, parasitism and food-related factors. Carcasses resulting from non-predatory mortality may undergo decomposition leading to an increase in microbial production and a shift in microbial composition in the water column. Alternatively, sinking carcasses may contribute significantly to vertical carbon flux especially outside the phytoplankton growth seasons, and become a food source for the benthos. Global climate change is already altering freshwater ecosystems on multiple levels, and likely will have significant positive or negative effects on zooplankton non-predatory mortality. Better spatial and temporal studies of zooplankton carcasses and non-predatory mortality rates will improve our understanding of this important but under-appreciated topic.
Zu rezensieren sind zwei Bücher von stattlichem Umfang, die ein gemeinsames Thema und ein gemeinsames Anliegen verbindet. Die Herausgeber beider Bände haben es sich zur Aufgabe gemacht, einen Reader vorzulegen, der die Forschung zum Thema "Deutsch in Ost und West" in ihrer historischen Entwicklung dokumentiert. Eine Reihe ausgewählter Beiträge - so das übereinstimmende Anliegen - soll nicht nur einen Überblick über wesentliche Phasen und Schwerpunkte der Forschung geben, sondern auch Orientierung und Anregung all denen bieten, die sich dem Thema künftig zuwenden wollen.

אל מול הצו המקראי של "לֹא תַעֲשֶׂה לְךָ פֶסֶל וְכָל תְּמוּנָה": שלושה ספרים חדשים על האמנות היהודית
(2022)
"מגילת שיר השירים היא יצירה עתיקה וחידתית. מילותיה הייחודיות שזורות ביד אמן. תשומת לב למלאכת רקמה עדינה זו ולהתכתבותה עם מקורות מקראיים אחרים פותחת נתיבי פרשנות מפתיעים. הספר 'מי זאת עולה מן המדבר' מציע שלוש קריאות במגילה ועונה לשאלה 'מי זאת' שלוש תשובות מהפכניות:• הקריאה הראשונה עוסקת ביחסים שבין גברים ונשים ובקשר שבין אהבה וחופש. הקול הנשי העולה בה הוא קולה של אישה המתבוננת בדפוסי הזוגיות המוכרים לה וקוראת לשינוי מהותי בהם.• הקריאה השנייה עוסקת ביחסים שבין האדם והאלוהות. הדמות הנשית המתגלה בו היא דמותה של האלוהות החושפת את מנגנוני הכוח שבממסד הדתי ומציעה לאדם קשר המושתת על חירות ואהבה.• בקריאה השלישית הדמות הנשית היא ההוויה כולה. היא עוסקת בקשר שבין ההוויה לתודעה האנושית החופשית במהותה ובאפשרות של השפה לחבר ביניהן באהבה.יחד, הקולות הנשיים הללו מציעים לנו, כחברה וכיחידים, תהליך צמיחה שבליבו אהבה וחירות החיוניות זו לקיומה של זו."שיר השירים הוא שירת הפצעה גדולה של אהבה. כוח אהבה, שאין דבר שישווה לו מבין כל כוחות עולם. אבל ההפצעה הזו, מקורה בפצע, פצע שכולנו נושאות ונושאים בתוכנו כבר דורי דורות, פצע הקשר בין גברים ונשים. כמה לא מתואמות יכולות להיות השפות שלנו על הציר המתעתע שבין תאווה לאהבה, כמה אי הלימה יכולה להיות בין שפת האם של השכינה והאשה, שפת אתיקה של אהבה, של נאמנות, לשפות אהבה שהן במסווה ובנתק. ואיך נצמיח בעולם אהבת אמת, עדינה, חופשייה ושלמה.פירושה של מרב מזא"ה הוא רגע היסטורי. בדור פצוע אהבה, בשפה ברורה ובהירה, שכבה אחר שכבה, בסבלנות ובחכמה של התגלות, לוקחת מרב את קוראיה למסע אל עומק הפצע. בהלימה בין תוכן המגילה לצורה בה בחרה לכתוב את פירושה, בבחירה ללכת עם הקוראים לאט את המסע כולו, פסוק אחר פסוק, במסע שכוחו לא רק בפענוח אלא גם בקצב המוענק לכל קורא על פי דרכו, נותנת מרב הזדמנות לכל אחת ואחד לצלול אל המגילה, לכאוב איתה ולהירפא מכוחה. מסע שיר השירים הוא הזמנה עתיקה ונמשכת שהגיעה שעתה, הזמנה לנשים וגברים לכאוב יחד את נתק הקשר, לשמוע זה את קולו של זו, לספר את פציעות הלב והגוף, ולהתגלות זו לזה במסע אמון ואמונה, איחוי וריפוי, מסע אהבת אמת העולה לרגל לירושלים, אל השלם." -- מן המעטפת האחורית.
