Subjects: Anthropology of Education, Hermeneutic Content Analysis, knowledge, education, Brazil

description: This paper aims to scrutinize, understand, and reflect on the construction and constitution of knowledge in the anthropology of education in Brazil. Hermeneutic content analysis (HCA) was used in this study to understand the scientific content and general sense of the analyzed papers. As a result of the scientific content analysis, the papers show two categories (a) proposition and dialogue/interfaces for an anthropology of education and (b) contributions of anthropology’s knowledge to the education field; whereas, the general sense analysis of the papers shows four categories (a) anthropology as a theoretical and methodical foundation for education, (b) the education concept and notion, (c) the image of the professional in the education field, and (d) the school as the research locus. The analysis indicated that the anthropology of education field in Brazil is reduced to a schooling of the anthropology of education and an anthropological determinism concealing educational problems and questions.

description: The study investigated the influence of parenting style, and parental involvement, on secondary school students’ academic performance, in Oriade Local Government Area, Osun State, Nigeria. The descriptive survey research design of the ex-post facto type was employed in the study. Respondents were 300 secondary school students, randomly drawn from 10 schools constituted the study sample. Two valid and reliable instruments (Parental Style and Parental Involvement Questionnaire (PSPIQ) and students’ score in English Language and mathematics) provided data for the study. The Bivariate and multiple regression statistical methods were used to analyze the data. Results obtained indicated that parenting style had no significant influence on students’ academic performance (F=0.478, P0.05). However, the positive regression coefficient revealed a positive influence of parenting style on students’ academic performance. Contrarily, parental involvement was observed to have positive and significant influence on students’ academic performance, (F=35.218, P0.05). The results further demonstrated no significant joint influence of parenting style and parental involvement on students’ academic performance (F=2.56, P0.05). Parental involvement exerted more influence on students’ academic performance than parenting style. Based on the results, the study suggested that school authorities should educate parents on the relationship between parenting style and students’ academic performance. Also, that parents should be close to their children, in order to abreast themselves with their school needs.

description: The present paper discusses a pathway to study pre-service teachers’ actual knowledge through their designed teaching activities on topics of Natural Sciences. Its importance lies on the assessment of teachers’ readiness and the effectiveness of their potential interventions. To this direction, a theoretical grid is proposed, which classifies teachers’ activities into four theoretical frameworks (empiricist, Piagetian, socio-cognitive, socio-cultural). The research was implemented to 17 3rd year students – future preschool teachers from the Department of Educational Sciences and Early Childhood Education of the University of Patras in Greece. Students were asked to design teaching plans about the rainbow phenomenon and their texts were analyzed qualitatively using the aforementioned grid. The results showed that most of the students approached the topic in the empiricist framework intentionally or not. Their difficulty to apply the theoretical frameworks into practice indicates the strong influence prior experiences have on the teachers and raises questions about the formal education’s effectiveness.

Crossmaps: A principled approach to ex-post data harmonisation and dataset integration
Creators: name: Huang, Cynthia A.
Publisher: name: Zenodo
Year: 2023

description: Researchers and practitioners spend considerable time and effort designing and producing merged datasets. Unfortunately, dataset designs and merged datasets can be very difficult to audit, modify or reuse. Even with knowledge of the programming language, decoding long custom data wrangling scripts can be prohibitively complex and time consuming. Ex-post harmonisation scripts are especially difficult because careful recoding, aggregation or redistribution of values is required to merge related datasets such as labour statistics collected under evolving occupation nomenclature.

Moreover, coordination and verification issues arise when data are produced and used by different parties such as in interdisciplinary teams. The design of a harmonised dataset might require domain or statistical expertise from team members without sufficient time or programming skills to implement the data transformations. Data wrangling may be delegated to other team members or research assistants, and may even require different software to the data analysis. Downstream data users often rely on ad hoc validation to check a merged dataset matches the intended design. Without adequate checks, errors can go undetected unless they produce obviously suspect results downstream.

In this talk, I present a new approach to describing, implementing and validating ex-post harmonisation and data transformations. I will also demonstrate how to implement this approach, and verify existing data integration workflows, using the xmap package in the R language. The proposed approach separates categorical recoding and nomenclature transformation operations from procedural code by encoding the transformations as machine-readable ‘crossmap’ objects. The crossmap structure extends standard crosswalk or lookup table approaches using graph and matrix representations of data transformations. It encodes relations between nomenclatures as directed, bipartite weighted graphs. Graph properties of a crossmap can be checked to ensure consistency with the harmonisation design, circumventing the need for ad hoc validation of the transformed data.
Universal correlators for multi-arc complex matrix models

description: The correlation functions of the multi-arc complex matrix model are shown to be universal for any finite number of arcs. The universality classes are characterized by the support of the eigenvalue density and are conjectured to fall into the same classes as the ones recently found for the hermitian model. This is explicitly shown to be true for the case of two arcs, apart from the known result for one arc. The basic tool is the iterative solution of the loop equation for the complex matrix model with multiple arcs, which provides all multi-loop correlators up to an arbitrary genus. Explicit results for genus one are given for any number of arcs. The two-arc solution is investigated in detail, including the double-scaling limit. In addition universal expressions for the string susceptibility are given for both the complex and hermitian model.

title: Specific job-anxiety in comparison to general psychosomatic symptoms at admission, discharge and six months after psychosomatic inpatient treatment

name: Linden, Michael
Publisher: name: Karger
Year: 2012
Subjects: subject: Job-anxiety, anxiety disorders, sick leave, participation disorders, return to work, rehabilitation
subject: 150

description: Objective: Job-anxiety is a severe problem in many patients with chronic mental disorders, as it is usually resulting in specific participation problems at the workplace and long-term sick leave. The aim of this study is to explore the development of sick leave in dependence of general psychosomatic complaints and job-anxiety from admission to a psychosomatic inpatient treatment until six months after discharge.
Method: A convenience sample of 91 patients, suffering from multiple mental disorders filled in self-rating questionnaires on job-anxiety (Job-Anxiety-Scale JAS) and on general psychosomatic symptom load (Symptom Checklist SCL-90-R) at the beginning, the end, and six months after discharge from an inpatient psychosomatic treatment. Additionally, sick leave status and employment status before and six months after the treatment were assessed.
Results: 15.4% of 91 patients were on sick leave before inpatient treatment and at follow-up (SS), 20.9% were fit for work at intake and follow-up (FF), 6.6% fit for work initially and on sick leave later (FS), and 57.1% on sick leave first and working at follow-up (SF).
In regard to general psychosomatic complaints there are initially high scores on the SCL, a marked reduction during inpatient treatment, and a bouncing back to initial levels at follow-up for all four patient groups. SS and FS patients show the highest scores at intake and follow-up. Concerning job-anxiety, SS patients have the highest scores at all three assessments, while FF patients have significantly lower scores, with only low variation between assessments. SF patients start with comparatively high scores of job-anxiety, which even increase before reentering work, but decrease in the follow-up period when they are confronted with work again. FS patients start low like the FF patients at intake, reduce their job-anxiety further till discharge but increase to higher scores at follow-up.
Conclusions: General psychosomatic symptom load and job-anxiety show a different course during treatment and are differently related to sick leave. General psychosomatic symptom load can be understood as a measure for the degree of the chronic illness status, whereas job-anxiety reflects specific additional context-related problems, i.e. problems with work. A core finding is that job-anxiety is related to work avoidance, but work exposure may reduce job-anxiety. This has direct consequences for putting patients on sick leave or not.

description: The method of constrained randomisation is applied to three-dimensional simulated galaxy distributions. With this technique we generate for a given data set surrogate data sets which have the same linear properties as the original data whereas higher order or nonlinear correlations are not preserved. The analysis of the original and surrogate data sets with measures, which are sensitive to nonlinearities, yields information about the existence of nonlinear correlations in the data. We demonstrate how to generate surrogate data sets from a given point distribution, which have the same linear properties (power spectrum) as well as the same density amplitude distribution. We propose weighted scaling indices as a nonlinear statistical measure to quantify local morphological elements in large scale structure. Using surrogates is is shown that the data sets with the same 2-point correlation functions have slightly different void probability functions and especially a different set of weighted scaling indices. Thus a refined analysis of the large scale structure becomes possible by calculating local scaling properties whereby the method of constrained randomisation yields a vital tool for testing the performance of statistical measures in terms of sensitivity to different topological features and discriminative power.

Asymmetric wave transmission through one dimensional lattices with cubic-quintic nonlinearity

Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: One dimensional lattice with an on-site cubic-quintic nonlinear response described by a cubic-quintic discrete nonlinear Schrödinger equation is tested for asymmetric wave propagation. The lattice is connected to linear side chains. Asymmetry is introduced by breaking the mirror symmetry of the lattice with respect to the center of the nonlinear region. Three cases corresponding to dimer, trimer and quadrimer are discussed with focus on the corresponding diode-like effect. Transmission coefficients are analytically calculated for left and right moving waves via backward transfer map. The different transmission coefficients for the left and right moving waves impinging the lattice give rise to a diode-like effect which is tested for different variations in asymmetry and site dependent coefficients. We show that there is a higher transmission for incoming waves with lower wavenumbers as compared to the waves with comparatively larger wavenumbers and a diode-like effect improves by increasing the nonlinear layers. We also show that in the context of transport through such lattices, the cooperation between cubic and quintic nonlinear response is not "additive". Finally, we numerically analyse Gaussian wave packet dynamics impinging on the CQDNLS lattice for all three cases.

description: A longstanding conjecture by Belinskii, Khalatnikov, and Lifshitz that the singularity in generic gravitational collapse is spacelike, local, and oscillatory is explored analytically and numerically in spatially inhomogeneous cosmological spacetimes. With a convenient choice of variables, it can be seen analytically how nonlinear terms in Einstein's equations control the approach to the singularity and cause oscillatory behavior. The analytic picture requires the drastic assumption that each spatial point evolves toward the singularity as an independent spatially homogeneous universe. In every case, detailed numerical simulations of the full Einstein evolution equations support this assumption.

First, we discuss the notion of manipulation in the classroom in relation to the nature of mathematical activity. Then, we present different practices of classroom play as well as elements of analysis of mathematical knowledge and classroom sessions. Finally, we propose an example of a game implemented at the end of primary school to work on calculation. We analyse this example of a mathematical workshop in terms of manipulation, play, analysis of mathematical knowledge and the course of the classroom sessions.

description: We show that a transformed Caldeira-Leggett Hamltonian has two distinct families of fixed points, rather than a single unique fixed point as often conjectured based on its connection to the anisotropic Kondo model. The two families are distinguished by a sharp qualitative difference in their quantum coherence properties and we argue that this distinction is best understood as the result of a transition in the model between degeneracy and non-degeneracy in the spectral function of the ``spin-flip'' operator.

From exemplar to copy: the scribal appropriation of a Hadewijch manuscript computationally explored

Publisher: name: arXiv
Year: 2022
Subjects: subject: Computation and Language (cs.CL)

description: This study is devoted to two of the oldest known manuscripts in which the oeuvre of the medieval mystical author Hadewijch has been preserved: Brussels, KBR, 2879-2880 (ms. A) and Brussels, KBR, 2877-2878 (ms. B). On the basis of codicological and contextual arguments, it is assumed that the scribe who produced B used A as an exemplar. While the similarities in both layout and content between the two manuscripts are striking, the present article seeks to identify the differences. After all, regardless of the intention to produce a copy that closely follows the exemplar, subtle linguistic variation is apparent. Divergences relate to spelling conventions, but also to the way in which words are abbreviated (and the extent to which abbreviations occur). The present study investigates the spelling profiles of the scribes who produced mss. A and B in a computational way. In the first part of this study, we will present both manuscripts in more detail, after which we will consider prior research carried out on scribal profiling. The current study both builds and expands on Kestemont (2015). Next, we outline the methodology used to analyse and measure the degree of scribal appropriation that took place when ms. B was copied off the exemplar ms. A. After this, we will discuss the results obtained, focusing on the scribal variation that can be found both at the level of individual words and n-grams. To this end, we use machine learning to identify the most distinctive features that separate manuscript A from B. Finally, we look at possible diachronic trends in the appropriation by B's scribe of his exemplar. We argue that scribal takeovers in the exemplar impacts the practice of the copying scribe, while transitions to a different content matter cause little to no effect.
Exploring intercultural capital through Greek teachers’ narratives

Subjects: Life narratives, educators, intercultural capital, habitus

description: This article focuses on the narratives of two Greek teachers working in public elementary schools. The research seeks to examine the teachers' life experiences in relation to the factors that constitute intercultural capital. Intercultural capital theory draws on Bourdieu's framework of capital and interprets the experiences of personal and professional developing during the various stages of life. This type of theorizing allows for teachers’ narratives to be viewed as a source of professional development and agency. Narrators focus on the primary habitus built on family capital resources and the secondary professional habitus based on educators' practice. Our data suggests that intercultural capital can server as a resource for the educators’ professional development and individual advancement. Teachers who can draw on a rich cultural heritage derived from a supportive family environment are more likely to accumulate highly valuable and widely transferable varieties of intercultural capital depending on their level of social integration.

description: This article presents the basic planning and results of a research project designed to explore the possibilities of transforming high school students' ideas about certain thermal concepts and phenomena. Asking the question "What is happening in this experiment and how can it be explained?", we proposed experimental situations in which students were confronted with research data juxtaposed with their knowledge from school courses and everyday reality. This qualitative research involved 30 15-year-old students. Analysis of the research data shows that students' ideas create obstacles to understanding phenomena, but that in some cases these can be overcome.

description: We study first-order logic (FO) over the structure consisting of finite words over some alphabet $A$, together with the (non-contiguous) subword ordering. In terms of decidability of quantifier alternation fragments, this logic is well-understood: If every word is available as a constant, then even the $Σ_1$ (i.e., existential) fragment is undecidable, already for binary alphabets $A$. However, up to now, little is known about the expressiveness of the quantifier alternation fragments: For example, the undecidability proof for the existential fragment relies on Diophantine equations and only shows that recursively enumerable languages over a singleton alphabet (and some auxiliary predicates) are definable. We show that if $|A|\ge 3$, then a relation is definable in the existential fragment over $A$ with constants if and only if it is recursively enumerable. This implies characterizations for all fragments $Σ_i$: If $|A|\ge 3$, then a relation is definable in $Σ_i$ if and only if it belongs to the $i$-th level of the arithmetical hierarchy. In addition, our result yields an analogous complete description of the $Σ_i$-fragments for $i\ge 2$ of the pure logic, where the words of $A^*$ are not available as constants.

description: Immigrants are typically found to have less wealth and hold it in different forms than the native born. These differences may affect both the economic assimilation of immigrants and overall portfolio allocation when immigrants are a large share of the population, as in New Zealand. In this paper, data from the 2001 Household Savings Survey are used to examine wealth differences between immigrants and the New Zealand-born. Differences in the allocation of portfolios between housing and other forms of wealth are described. Unconditional and conditional wealth quantiles are examined using parametric models. Semiparametric methods are used to decompose differences in net worth at different parts of the wealth distribution into the part due to differences in characteristics and the part due to differences in the returns to characteristics.

subject: 150

description: Background: Health problems are often associated with activity limitations and participation restrictions, as defined in the International Classification of Functioning, Disability and Health (ICF). This often affects the workplace in the form of sick leave or a reduction in productivity. The question is: to what extent are participation restrictions at work related to participation restrictions in other domains of life?
Method: A total of 382 primary health care patients (aged 18-65) were asked to provide information on their employment status, perceived health-related workplace problems and sick leave status. Health-dependent participation restrictions across different domains of life were assessed using the Index for Measuring Participation Restrictions (IMET)self rating questionnaire.
Results: Currently unemployed patients reported significantly higher degrees of participation restrictions across all domains of life than the employed participants. Employed patients with workplace problems scored higher than patients without workplace problems. The domain of work encompassed the highest level of impairment, while the lowest was observed in personal relationships.
Conclusion: Workplace problems occur frequently for primary health care patients. They coincide with participation restrictions in other domains of life. For patients who complain about their capacity to work, diagnosis and treatment must not only focus on the work domain, but also enquire into and consider participation restrictions in other domains of life.

description: Performing classification on noisy, crowdsourced image datasets can prove challenging even for the best neural networks. Two issues which complicate the problem on such datasets are class imbalance and ground-truth uncertainty in labeling. The AL-ALL and AL-PUB datasets - consisting of tightly cropped, individual characters from images of ancient Greek papyri - are strongly affected by both issues. The application of ensemble modeling to such datasets can help identify images where the ground-truth is questionable and quantify the trustworthiness of those samples. As such, we apply stacked generalization consisting of nearly identical ResNets with different loss functions: one utilizing sparse cross-entropy (CXE) and the other Kullback-Liebler Divergence (KLD). Both networks use labels drawn from a crowd-sourced consensus. This consensus is derived from a Normalized Distribution of Annotations (NDA) based on all annotations for a given character in the dataset. For the second network, the KLD is calculated with respect to the NDA. For our ensemble model, we apply a k-nearest neighbors model to the outputs of the CXE and KLD networks. Individually, the ResNet models have approximately 93% accuracy, while the ensemble model achieves an accuracy of > 95%, increasing the classification trustworthiness. We also perform an analysis of the Shannon entropy of the various models' output distributions to measure classification uncertainty. Our results suggest that entropy is useful for predicting model misclassifications.

description: A recurrent task in coordinated systems is managing (estimating, predicting, or controlling) signals that vary in space, such as distributed sensed data or computation outcomes. Especially in large-scale settings, the problem can be addressed through decentralised and situated computing systems: nodes can locally sense, process, and act upon signals, and coordinate with neighbours to implement collective strategies. Accordingly, in this work we devise distributed coordination strategies for the estimation of a spatial phenomenon through collaborative adaptive sampling. Our design is based on the idea of dynamically partitioning space into regions that compete and grow/shrink to provide accurate aggregate sampling. Such regions hence define a sort of virtualised space that is "fluid", since its structure adapts in response to pressure forces exerted by the underlying phenomenon. We provide an adaptive sampling algorithm in the field-based coordination framework, and prove it is self-stabilising and locally optimal. Finally, we verify by simulation that the proposed algorithm effectively carries out a spatially adaptive sampling while maintaining a tuneable trade-off between accuracy and efficiency.

description: Existing models for the analysis of concurrent processes tend to focus on fail-stop failures, where processes are either working or permanently stopped, and their state (working/stopped) is known. In fact, systems are often affected by grey failures: failures that are latent, possibly transient, and may affect the system in subtle ways that later lead to major issues (such as crashes, limited availability, overload). We introduce a model of actor-based systems with grey failures, based on two interlinked layers: an actor model, given as an asynchronous process calculus with discrete time, and a failure model that represents failure patterns to inject in the system. Our failure model captures not only fail-stop node and link failures, but also grey failures (e.g., partial, transient). We give a behavioural equivalence relation based on weak barbed bisimulation to compare systems on the basis of their ability to recover from failures, and on this basis we define some desirable properties of reliable systems. By doing so, we reduce the problem of checking reliability properties of systems to the problem of checking bisimulation.
Ab Initio Models of Dislocations

description: This chapter reviews the different methodological aspects of the ab ini-tio modeling of dislocations. Such simulations are now frequently used to study the dislocation core, i.e. the region in the immediate vicinity of the line defect where the crystal is so strongly distorted that an atomic description is needed. This core region controls some dislocation fundamental properties, like their ability to glide in different crystallographic planes. Ab initio calculations based on the density functional theory offer a predictive way to model this core region. Because dislocations break the periodicity of the crystal and induce long range elastic fields, several specific approaches relying on different boundary conditions have been developed to allow for the atomistic modeling of these defects in simulation cells having a size compatible with ab initio calculations. We describe these different approaches which can be used to study dislocations with ab initio calculations and introduce the different analyses which are currently performed to characterize the core structure, before discussing how meaningful energy properties can be extracted from such simulations.

description: There is a general consensus that diagnoses for mental disorders should be based on criteria and
algorithms as given in ICD or DSM. Standardized clinical interviews are recommended as
diagnostic methods. In ICD and DSM much emphasis is put on algorithms, while the underlying
criteria get much less attention. The question is how valid criteria are which are collected by
structured diagnostic interviews.
15 patients from a cardiology inpatient unit, interviewed with the Mini International
Neuropsychiatric Interview (MINI). 32 (15.3%) were diagnosed as suffering from a major
depressive episode or dysthymia. Additionally a thorough clinical examination was done by a
psychiatric expert.
In one out of these 15 patients the standardized diagnosis of present major depression was
reaffirmed. In total, four patients were suffering from some kind of depressive disorder presently
or life time. Two patients were suffering from anxiety disorders, two from adjustment disorders,
and four from different types of organic brain disorders. Most important, there are 3 out of 15
who are not mentally ill.
Our observations show that standardized diagnostic interviews cannot be used to make specific
differential diagnoses, but rather catch unspecific syndromes. This is partly due to the fact that
the wording, definition, and understanding of the underlying criteria is rather vague. This is an
even greater problem if there is any somatic comorbidity. In the revision of ICD and DSM, a glossary of psychopathological terms and guidelines for the training of clinicians should be
included.

description: The use of digital models in the creation of the mental image of abstract concepts remains a breath of fresh air for the teaching and learning of technical sciences in Tunisia, a path for thousands of teachers of technical sciences terminal classes, deprived of didactic materials and experiments. The use of ICT in general and specifically of simulation and digital models in the field of technical drawing education in technology, are didactic means that allow access and dissemination of information at high speed. It also allows teachers to create and innovate in the acquisition and learning of skills. Thus, our research focuses on the notion of appropriation of three-dimensional perception and the creation of the mental image in learners through the use of digital models in learning to read and write a technical drawing. for students in the final classes of technical sciences. In effect: (1) Is the writing of a definition drawing sufficient to enable the student to easily read an overall plan? (2) Can the reasoned use of new information and communication technology remedy the problems of reading an overall plan? At the end of our study, we were able to verify that: (1) Mastering the writing of a definition drawing does not develop the learner's ability to read an assembly drawing. (2) The representation of an overall drawing on a computer contributes to learning to read it. (3) Digital models have major advantages over traditional graphical representation tools and can help learners understand mechanical systems. (4) The digital models by their complete and dynamic representations, contribute to the creation of mental image at the learner and thus to facilitate the reading of the assembly drawings.

description: Eine krankheitsbedingte Fähigkeitsstörung entscheidet erst im Zusammenhang mit dem Kontext (z.B. Rollenanforderungen bei der Arbeit) über das Ausmaß der Krankheitsfolgen, d.h. der Partizipationsstörung. Bei der sozialmedizinischen Leistungsbeurteilung ist eine Beschreibung der Fähigkeitsbeeinträchtigungen erforderlich, die der Betroffene aufgrund seiner Gesundheitsstörungen hat, bzw. der Aktivitäten die er erkrankungsbedingt nicht verrichten kann. Dazu notwendig ist die Kenntnis des Kontexts, d.h. des Leistungsanforderungsprofils auf das sich die Beurteilung bezieht.

description: It is well known that grain boundaries (GBs) have a strong influence on mechanical properties of polycrystalline materials. Not as well-known is how different GBs interact with dislocations to influence dislocation movement. This work presents a molecular dynamics study of 33 different FCC Ni bicrystals, each subjected to four different strain states to induce incident dislocation-GB interactions for 132 unique configurations. The resulting simulations are analyzed to determine properties of the interaction that affect the likelihood of transmission of the dislocation through the GB in an effort to better inform mesoscale models of dislocation movement within polycrystals. It is found that the ability to predict the slip system of a transmitted dislocation using common geometric criteria is confirmed. Furthermore, machine learning processes are implemented revealing that geometric properties, such as the minimum potential residual Burgers vector (RBV) and the disorientation between the two grains, are stronger indicators of whether or not a dislocation would transmit than other properties, such as the resolved shear stress.

description: Information of patients about their illness is necessary for patient empowerment and coping with illness. This can be done by written material, i.e. bibliotherapy [1-6]. Scientific data suggest that bibliotherapy can help patients to better understand their illness, improve their health behaviour, and reduce anxiety [2, 3, 7]. The objective of the present study is to investigate in a randomized controlled trial the effects of bibliotherapy on illness-related knowledge, i.e. health literacy, and on heart-related anxiety in cardiology patients.
Recent Advances in Thermoelectric Performance of Half-Heusler Compounds

description: Half-Heusler phases (space group F43m, C1b) have recently captured much attention as promising thermoelectric materials for heat-to-electric power conversion in the mid-to-high temperature range. The most studied ones are the RNiSn-type half-Heusler compounds, where R represents refractory metals Hf, Zr, and Ti. These compounds have shown a high-power factor and high-power density, as well as good material stability and scalability. Due to their high thermal conductivity, however, the dimensionless figure of merit (zT) of these materials has stagnated near 1 for a long time. Since 2013, the verifiable ZT of half-Heusler compounds has risen from 1 to near 1.5 for both n- and p-type compounds in the temperature range of 500 to 900 degrees C. In this brief review, we summarize recent advances as well as approaches in achieving the high ZT reported. In particular, we discuss the less-exploited strain-relief effect and dopant resonant state effect studied by the author and his collaborators in more detail. Finally, we point out directions for further development. Keywords: half-Heusler compounds; figure of merit; power density; lattice disorder; dopant resonant states

description: Objective: Similar to the spectrum of the traditional anxiety disorders, there are also different types of workplace-related anxieties. The question is whether in different professional settings different facets of workplace-related anxieties are predominant.
Methods: A convenience sample of 224 inpatients (71% women) from a department of psychosomatic medicine was investigated. They were assessed with a structured diagnostic interview concerning anxiety disorders and specific workplace-related anxieties.
Results: Office workers suffer relatively most often from specific social anxiety, insufficiency, and workplace phobia. Service workers suffer predominantly from unspecific social anxiety. Health care workers are characterized by insufficiency, adjustment disorders, PTSD and workplace phobia. Persons in production and education are least often affected by workplace-related anxieties.
Conclusions: Different types of anxiety are seen in different professional domains, parallel to workplace characteristics.

description: Arbeitsplätze besitzen ihrer Natur nach zahlreiche potentiell angstauslösende oder angstverstärkende Charakteristika. Manifestieren sich arbeitsbezogene Ängste, können Absentismus, Langzeitarbeitsunfähigkeit bis hin zur Erwerbsunfähigkeit die Folgen sein. Bei Rehabilitanden findet man in 30–60% der Fälle arbeitsbezogene Ängste, die die berufliche Wiedereingliederung erschweren. Aber auch bei psychisch gesunden Erwerbstätigen wurde bei 5 % der Beschäftigten eine arbeitsangstbedingte Neigung zur Krankschreibung gefunden. In der zukünftigen Forschung sollte arbeitsbezogenen Ängsten nicht erst in der Rehabilitation, sondern bereits präventiv am Arbeitsplatz selbst Aufmerksamkeit geschenkt werden. Das Konzept bietet Ansatzpunkte für psychische Gefährdungsanalysen, sowie Arbeitsplatzgestaltung und –passung.

Proximal gradient methods beyond monotony

description: We address composite optimization problems, which consist in minimizing the sum of a smooth and a merely lower semicontinuous function, without any convexity assumptions. Numerical solutions of these problems can be obtained by proximal gradient methods, which often rely on a line search procedure as globalization mechanism. We consider an adaptive nonmonotone proximal gradient scheme based on an averaged merit function and establish asymptotic convergence guarantees under weak assumptions, delivering results on par with the monotone strategy. Global worst-case rates for the iterates and a stationarity measure are also derived. Finally, a numerical example indicates the potential of nonmonotonicity and spectral approximations.

description: We report on first experimental signatures for chaos-assisted tunneling in a two-dimensional annular billiard. Measurements of microwave spectra from a superconducting cavity with high frequency resolution are combined with electromagnetic field distributions experimentally determined from a normal conducting twin cavity with high spatial resolution to resolve eigenmodes with properly identified quantum numbers. Distributions of so-called quasi-doublet splittings serve as basic observables for the tunneling between whispering gallery type modes localized to congruent, but distinct tori which are coupled weakly to irregular eigenstates associated with the chaotic region in phase space.
