National Action Plans (NAPs) have been increas-ingly adopted world-wide after the Vienna Dec-laration in 1993, where it was urged to consider the improvement and promotion of Human Rights. In this paper, we discuss their usefulness and success by analysing the challenges present-ed during NAP processes as well as the benefits this set of actions entails: The challenges for their implementation outweigh its actual benefits. Nevertheless, NAPs have great potential. Based on new research, we elaborate a set of recom-mendations for improving the design and imple-mentation of national action planning. In order to effectively bring NAP into practice, we consider it crucial to plan and analyse every state local circumstances in detail. The latter is important, since the implementation of a concrete set of actions is intended to directly transform and improve the local living conditions of the people. In a long-term perspective, we defend the benefit of NAP’s implementation for complying obliga-tions set up by HR treaties.

Cyber-physical systems often encompass complex concurrent behavior with timing constraints and probabilistic failures on demand. The analysis whether such systems with probabilistic timed behavior adhere to a given specification is essential. When the states of the system can be represented by graphs, the rule-based formalism of Probabilistic Timed Graph Transformation Systems (PTGTSs) can be used to suitably capture structure dynamics as well as probabilistic and timed behavior of the system. The model checking support for PTGTSs w.r.t. properties specified using Probabilistic Timed Computation Tree Logic (PTCTL) has been already presented. Moreover, for timed graph-based runtime monitoring, Metric Temporal Graph Logic (MTGL) has been developed for stating metric temporal properties on identified subgraphs and their structural changes over time. In this paper, we (a) extend MTGL to the Probabilistic Metric Temporal Graph Logic (PMTGL) by allowing for the specification of probabilistic properties, (b) adapt our MTGL satisfaction checking approach to PTGTSs, and (c) combine the approaches for PTCTL model checking and MTGL satisfaction checking to obtain a Bounded Model Checking (BMC) approach for PMTGL. In our evaluation, we apply an implementation of our BMC approach in AutoGraph to a running example.
Die Reform des Gemeinsamen Europäischen Asylsystems (GEAS) ist eine der größten Herausforderungen und eine der drängendsten Aufgaben der EU und ihrer Mitgliedstaaten. Dabei stellt die Frage der „gerechten Lastenteilung“ in der Asyl- und Migrationspolitik den Zusammenhalt der EU auf eine Zerreißprobe. Seit den gescheiterten Verhandlungen über die GEAS-Reform 2016/2017 versuchen die Mitgliedstaaten, einen Ausgleich zwischen den Grundsätzen der Solidarität und Verantwortlichkeit zu finden, wie es Art. 80 AEUV für das GEAS vorgibt. Je nach Interessenlage verbirgt sich dahinter aber ein sehr unterschiedliches Verständnis.
Diese Arbeit untersucht die Reformbemühungen beim GEAS nach Vorlage der Kommissionsvorschläge im September 2020 und beleuchtet die divergierenden Interessenlagen der Mitgliedstaaten hinsichtlich Aufnahme und Verteilung von Geflüchteten. Ziel der Arbeit ist, eine Aussage über die Erfolgsaussichten einer Einigung über die Grundsätze der Solidarität und Verantwortung zu treffen. Dazu werden zunächst die Verpflichtungen im Asylrecht basierend auf internationalen Übereinkommen wie der Genfer Flüchtlingskonvention dargestellt. An-schließend werden GEAS und Dublin-System, das dem Ersteinreisestaat die Zuständigkeit für die Asylverfahren zuschreibt, und die Ursachen für sein Scheitern analysiert.
Diese Verantwortungsteilung, die zu einer überproportionalen Belastung der Mitgliedstaaten im Süden führt, ist Kristallisationspunkt für Konflikte, gegenseitigen Vorwürfe und Misstrau-en zwischen den Mitgliedstaaten. Infolge einer tatsächlichen Überlastung und teilweise selbst verschuldeten Unmöglichkeit, die GEAS-Verpflichtungen zu erfüllen, rufen die Südstaaten nach Unterstützung aus dem Norden und betreiben teilweise sogar eine Politik des Laissez-Passer. Durch teilweise katastrophale Zustände bei Verfahren, Unterbringung und Versorgung der Geflüchteten entstehen Rückführungshindernisse und Druck auf die Zielstaaten, mehr Solidarität zu leisten.
Ausgehend von diesem Befund wird der Bedeutungsgehalt des Solidaritätsprinzips in Art. 80 AEUV in normativer und deskriptiver Hinsicht untersucht. Normativ handelt es sich dabei um eine abstrakte Rechtspflicht zur gegenseitigen Unterstützung, deren Ausgestaltung im politischen Ermessen der Mitgliedstaaten liegt. Deskriptiv kann unter „Solidarität“ der Zweck verstanden werden, dass die Verwirklichung individueller Interessen einer kollektiven Anstrengung bedarf, die wiederum das Gemeinwohl fördert und somit im Interesse aller liegt. Dem folgend müssten alle Mitgliedstaaten ein Interesse an der Bewältigung der Herausforderungen der Migration nach Europa haben.
Die Interessen der Mitgliedstaten deuten aber auf etwas anderes hin. Die durch die Ankünfte von Schutzsuchenden aus dem Süden stark belasteten Mittelmeeranrainer wie Griechenland und Italien fordern eine Abkehr vom Dublin-System. Die migrationskritischen Visegrád-Staaten verweigern im Grunde jede Unterstützung bei der Aufnahme und berufen sich darauf, dass sie ihre rechtlichen Verpflichtungen erfüllen. Staaten, die lange Zeit eine liberale Migrationspolitik verfolgten und beliebte Zielländer waren wie Schweden, ringen nach der Migrationskrise 2015/2016 mit sich auf der Suche nach einem migrationspolitischen Kurs, der rechts-populistische Kräfte nicht noch weiter erstarken lässt. Auch die Hauptzielländer Deutschland und Frankreich versuchen den jeweiligen innenpolitischen Diskursen entsprechend, die Sekundärmigration zu verhindern und wollen auf unterschiedliche Weise die Außengrenzstaaten unterstützen, wobei Deutschland die Umverteilung aller unterstützt.
Die im September 2020 vorgelegten Vorschläge der Kommission versuchen, den unterschiedlichen Interessen Rechnung zu tragen. Durch die Schaffung eines Grenzverfahrens soll die Anzahl der in die EU einreisenden und zu verteilenden Geflüchteten reduziert werden. Durch Änderung der Dublin-Kriterien soll die Zuständigkeit der potentiellen Zielländer erweitert werden, um die Südländer zu entlasten und der Sekundärmigration entgegenzuwirken. Mit der gleichen Zielrichtung soll auf Grundlage eines neuen Solidaritätsmechanismus eine Umverteilung unbegleiteter Minderjähriger und aus Seenot Geretteter erfolgen. In Krisenzeiten soll daraus eine generelle Umverteilung aller Schutzsuchenden erwachsen, wobei Solidarität weiterhin auf verschiedene Art und Weise geleistet werden können soll.
Angesichts der Verhandlungen während der deutschen EU-Ratspräsidentschaft und des er-reichten Zwischenergebnisses besteht Skepsis, dass die Mitgliedstaaten sich bald auf eine GEAS-Reform einigen werden. Dazu liegen die Interessen der Mitgliedstaaten auch hinsichtlich der Solidarität zu weit auseinander. Zudem stellt sich die in Hinblick auf die europäische Integration und die Zukunft der EU besorgniserregende Frage, worin das im Interesse aller liegende Gemeinwohl in der Asylpolitik liegen soll, das die gemeinsame Kraftanstrengung zu einem individuellen Interesse jedes Einzelnen werden lässt. Denn anders als bei der Schaffung des Schengen-Raums als Raum ohne Binnengrenzen sind Wohlstandsgewinne von der Aufnahme Geflüchteter vorerst nicht zu erwarten.
Writing travel, writing life
(2022)
The book compares the texts of three Swiss authors: Ella Maillart, Annemarie Schwarzenbach and Nicolas Bouvier. The focus is on their trip from Genève to Kabul that Ella Maillart and Annemarie Schwarzenbach made together in 1939/1940 and Nicolas Bouvier 1953/1954 with the artist Thierry Vernet. The comparison shows the strong connection between the journey and life and between ars vivendi and travel literature.
This book also gives an overview of and organises the numerous terms, genres, and categories that already exist to describe various travel texts and proposes the new term travelling narration. The travelling narration looks at the text from a narratological perspective that distinguishes the author, narrator, and protagonist within the narration.
In the examination, ten motifs could be found to characterise the travelling narration: Culture, Crossing Borders, Freedom, Time and Space, the Aesthetics of Landscapes, Writing and Reading, the Self and/as the Other, Home, Religion and Spirituality as well as the Journey. The importance of each individual motif does not only apply in the 1930s or 1950s but also transmits important findings for living together today and in the future.
Background: In the animal kingdom body size is often linked to dominance and subsequently the standing in social hierarchy. Similarly, human growth has been associated and linked to socioeconomic factors, including one’s social status. This has already been proposed in the early 1900s where data on young German school girls from different social strata have been compared.
Objectives: This paper aims to summarize and analyze these results and make them accessible for non-German speakers. The full English translation of the historic work of Dikanski (Dikanski, 1914) is available as a supplement. Further, this work aims to compare the historical data with modern references, to test three hypotheses: (1) higher social class is positively associated with body height and weight, (2) affluent people from the used historical data match modern references in weight and height and (3) weight distributions are skewed in both modern and historical populations.
Methods: Comparison of historical data from 1914 with WHO and 1980s German data. The data sets, for both body weight and height for 6.0- and 7.0-year-old girls, were fitted onto centile curves and quantile correlation coefficients were calculated.
Results: In historical data social status is positively associated with body height and weight while both are also normally distributed, which marks a significant difference to modern references.
Conclusion: Social status is positively associated with height, signaling social dominance, making children of affluent classes taller. Children from the historical data do not reach the average height of modern children, even under the best environmental conditions. The children of the upper social class were not skewed in weight distribution, although they had the means to become as obese as modern children.
Background: Network models are useful tools for researchers to simplify and understand investigated systems. Yet, the assessment of methods for network construction is often uncertain. Random resampling simulations can aid to assess methods, provided synthetic data exists for reliable network construction.
Objectives: We implemented a new Monte Carlo algorithm to create simulated data for network reconstruction, tested the influence of adjusted parameters and used simulations to select a method for network model estimation based on real-world data. We hypothesized, that reconstructs based on Monte Carlo data are scored at least as good compared to a benchmark.
Methods: Simulated data was generated in R using the Monte Carlo algorithm of the mcgraph package. Benchmark data was created by the huge package. Networks were reconstructed using six estimator functions and scored by four classification metrics. For compatibility tests of mean score differences, Welch’s t-test was used. Network model estimation based on real-world data was done by stepwise selection.
Samples: Simulated data was generated based on 640 input graphs of various types and sizes. The real-world dataset consisted of 67 medieval skeletons of females and males from the region of Refshale (Lolland) and Nordby (Jutland) in Denmark.
Results: Results after t-tests and determining confidence intervals (CI95%) show, that evaluation scores for network reconstructs based on the mcgraph package were at least as good compared to the benchmark huge. The results even indicate slightly better scores on average for the mcgraph package.
Conclusion: The results confirmed our objective and suggested that Monte Carlo data can keep up with the benchmark in the applied test framework. The algorithm offers the feature to use (weighted) un- and directed graphs and might be useful for assessing methods for network construction.
Background: Clinicians often refer anthropometric measures of a child to so-called “growth standards” and “growth references. Over 140 countries have meanwhile adopted WHO growth standards.
Objectives: The present study was conducted to thoroughly examine the idea of growth standards as a common yardstick for all populations. Weight depends on height. We became interested in whether also weight-for-height depends on height. First, we studied the age-group effect on weight-for-height. Thereafter, we tested the applicability of weight-for-height references in short and in historic populations.
Sample and Methods: We analyzed body height and body weight and weight-for-height of 3795 healthy boys and 3726 healthy girls aged 2 to 5 years measured in East-Germany between 1986 and 1990.
We chose contemporary height and weight charts from Germany, the UK, and the WHO growth chart and compared these with three geographically commensurable growth charts from the end of the 19th century.
Results: We analyzed body height and body weight and weight-for-height of 3795 healthy boys and 3726 healthy girls aged 2 to 5 years measured in East-Germany between 1986 and 1990.
We chose contemporary height and weight charts from Germany, the UK, and the WHO growth chart and compared these with three geographically commensurable growth charts of the end of the 19th century.
Conclusion: Weight-for-height depends on age and sex and apart from the nutritional state, reflects body proportion and body built particularly during infancy and early childhood. Populations with a relatively short average height are prone to high values of weight-for-height for arithmetic reasons independent of the nutritional state.
Background: Biological age markers are a crucial indicator whether children are decelerated in growth tempo. Skeletal maturation is the standard measure. Yet, it relies on exposing children to x-radiation. Dental eruption is a potential, but highly debated, radiation free alternative.
Objectives: We assess the interrelationship between dental eruption and other maturational markers. We hypothesize that dental age correlates with body height and skeletal age. We further evaluate how the three different variables behave in cohorts from differing social backgrounds.
Sample and Method: Dental, skeletal and height data from the 1970s to 1990s from Guatemalan boys were converted into standard deviation scores, using external references for each measurement. The boys, aged between 7 and 12, derived from different social backgrounds (middle SES (N = 6529), low-middle SES (N = 736), low SES Ladino (N = 3653) and low SES Maya (N = 4587).
Results: Dental age shows only a weak correlation with skeletal age (0.18) and height (0.2). The distinction between cohorts differs according to each of the three measurements. All cohorts differ significantly in height. In skeletal maturation, the middle SES cohort is significantly advanced compared to all other cohorts. The periodically malnourished cohorts of low SES Mayas and Ladinos are significantly delayed in dental maturation compared to the well-nourished low-middle and middle class Ladino children.
Conclusion: Dental development is an independent system, that is regulated by different mechanisms than skeletal development and growth. Tooth eruption is sensitive to nutritional status, whereas skeletal age is more sensitive to socioeconomic background.
Students learn by repetition. Repetition is essential, but repetition needs questioning, and questioning the repertoire belongs to the essential tasks of student education. Guiding students to questioning was and is our prime motive to offer our International Student Summer Schools. The data were critically discussed among the students, in the twilight of Just So Stories, common knowledge, and prompted questioning of contemporary solutions. For these schools, the students bring their own data, carry their preliminary concepts, and in group discussions, they may have to challenge these concepts. Catch-up growth is known to affect long bone growth, but different opinions exist to what extent it also affects body proportions. Skeletal age and dental development are considered appropriate measures of maturation, but it appears that both system develop independently and are regulated by different mechanisms. Body weight distributions are assumed to be skewed, yet, historic data disproved this assumption. Many discussions focused on current ideas of global growth standards as a common yardstick for all populations world-wide, with new statistical tools being developed including network reconstruction and evaluation of the reconstructs to determine the confidence of graph prediction methods.
