description: Originating in Girard's Linear logic, Ehrhard and Regnier's Taylor expansion of $λ$-terms has been broadly used as a tool to approximate the terms of several variants of the $λ$-calculus. Many results arise from a Commutation theorem relating the normal form of the Taylor expansion of a term to its Böhm tree. This led us to consider extending this formalism to the infinitary $λ$-calculus, since the $Λ_{\infty}^{001}$ version of this calculus has Böhm trees as normal forms and seems to be the ideal framework to reformulate the Commutation theorem.
 We give a (co-)inductive presentation of $Λ_{\infty}^{001}$. We define a Taylor expansion on this calculus, and state that the infinitary $β$-reduction can be simulated through this Taylor expansion. The target language is the usual resource calculus, and in particular the resource reduction remains finite, confluent and terminating. Finally, we state the generalised Commutation theorem and use our results to provide simple proofs of some normalisation and confluence properties in the infinitary $λ$-calculus.

description: Knowing in-service teachers’ motives is important for understanding career choices, retention and participation in lifelong learning. We explored In-service Teachers’ motives for Initial Teacher Education and participation in continuous professional development using a mixed method approach. A questionnaire combining closed-ended items with open-ended items was used to collect data from a convenient sample of seventy-seven in-service teachers. Mean scores were used to determine motives and drivers for participation. Content analysis was used to interpret individuals’ views and experiences. First, the study revealed that in-service teachers had closely related aspirations, that is, to attain higher qualifications, increase chances for job change and higher earnings. Second, based on mean scores less than 2.5, in-service teachers were neither attracted to teaching by social nor extrinsic factors. The mean scores greater than 3, meant that in-service teachers were attracted to teaching by intrinsic and altruistic factors. Third, our study revealed that the Teacher Capacity Development programme was attractive because of a combination sponsorship and specialism areas offered by the institution. We recommend that universities to find ways of reducing fees and to provide affordable accommodation, as ways to increase enrolments. Furthermore, the government should sponsor the training of teachers as it does other social services sectors like nursing and the police.

description: Asteroseismology has been impressively boosted during the last decade mainly thanks to space missions such as Kepler/K2 and CoRoT. This has a large impact, in particular, in exoplanetary sciences since the accurate characterization of the exoplanets is convoluted in most cases with the characterization of their hosting star. Until the expected launch of the ESA mission PLATO 2.0, there is almost a decade where only two important missions will provide short-cadence high-precision photometric time-series: NASA--TESS and ESA--CHEOPS missions, both having high capabilities for exoplanetary sciences. In this work, we want to explore the asteroseismic potential of CHEOPS time-series. Following the works done for estimating the asteroseismic potential of Kepler and TESS, we have analyzed the probability of detecting solar-like pulsations using CHEOPS light-curves. Since CHEOPS will collect runs with observational times from hours up to a few days, we have analyzed the accuracy and precision we can obtain for the estimation of nu_max, the only asteroseismic observable we can recover using CHEOPS observations. Finally, we have analyzed the impact of knowing nu_max in the characterization of exoplanet host stars. Using CHEOPS light-curves with the expected observational times we can determine nu_max for massive G and F-type stars from late Main Sequence on, and for F, G, and K-type stars from post-Main Sequence on with an uncertainty lower than a 5%. For magnitudes V<12 and observational times from eight hours up to two days, the HR zone of potential detectability changes. The determination of nu_max leads to an internal age uncertainty reduction in the characterization of exoplanet host stars from 52% to 38%; mass uncertainty reduction from 2.1% to 1.8%; radius uncertainty reduction from 1.8% to 1.6%; density uncertainty reduction from 5.6% to 4.7%, in our best scenarios.

description: Frustrated spin-systems have traditionally proven challenging to understand, owing to a scarcity of controlled methods for their analyses. By contrast, under strong magnetic fields, certain aspects of spin systems admit simpler and universal description in terms of hardcore bosons. The bosonic formalism is anchored by the phenomenon of Bose-Einstein condensation (BEC), which has helped explain the behaviors of a wide range of magnetic compounds under applied magnetic fields. Here, we focus on the interplay between frustration and externally applied magnetic field to identify instances where the BEC paradigm is no longer applicable. As a representative example, we consider the antiferromagnetic $J_1 - J_2 - J_3$ model on the square lattice in the presence of a uniform external magnetic field, and demonstrate that the frustration-driven suppression of the Néel order leads to a Lifshitz transition for the hardcore bosons. In the vicinity of the Lifshitz point, the physics becomes unmoored from the BEC paradigm, and the behavior of the system, both at and below the saturation field, is controlled by a Lifshitz multicritical point. We obtain the resultant universal scaling behaviors, and provide strong evidence for the existence of a frustration and magnetic-field driven correlated bosonic liquid state along the entire phase boundary separating the Néel phase from other magnetically ordered states.

description: We consider a class of problems of Discrete Tomography which has been deeply investigated in the past: the reconstruction of convex lattice sets from their horizontal and/or vertical X-rays, i.e. from the number of points in a sequence of consecutive horizontal and vertical lines. The reconstruction of the HV-convex polyominoes works usually in two steps, first the filling step consisting in filling operations, second the convex aggregation of the switching components. We prove three results about the convex aggregation step: (1) The convex aggregation step used for the reconstruction of HV-convex polyominoes does not always provide a solution. The example yielding to this result is called \textit{the bad guy} and disproves a conjecture of the domain. (2) The reconstruction of a digital convex lattice set from only one X-ray can be performed in polynomial time. We prove it by encoding the convex aggregation problem in a Directed Acyclic Graph. (3) With the same strategy, we prove that the reconstruction of fat digital convex sets from their horizontal and vertical X-rays can be solved in polynomial time. Fatness is a property of the digital convex sets regarding the relative position of the left, right, top and bottom points of the set. The complexity of the reconstruction of the lattice sets which are not fat remains an open question.

description: It is well known that the perturbation equations of massless fields for the Kerr-de Sitter geometry can be written in the form of separable equations. The equations have five definite singularities so that the analysis has been expected to be difficult. We show that these equations can be transformed to Heun's equations, for which we are able to use known technique for the analysis of the solutions. We reproduce results known previously for the Kerr geometry and de Sitter geometry in the confluent limits of the Heun's functions. Our analysis applies can be extended to Kerr-Newman-de Sitter geometry for massless fields with spin 0 and 1/2.

description: Background: The aim of occupational health care management programs (OHMP) is to improve the health status of employees, increase work ability and reduce absence time. As better health is associated with better coping abilities, work-related self-efficacy and self-management are important abilities that should be trained within OHMPs.
Objectives: To study the effectiveness of an OHMP including special interventions to enhance self-efficacy and self-management.
Methods: Effects of an OHMP on sickness absence was studied by comparing an intervention group of 159 employees and two control groups with 250 employees from the German Federal Pension Agency. A core feature of the OHMP were group sessions with all members of working teams, focussing on self-efficacy and self management of the individual participant as well as the team as a group (focus groups). Participants in the OHMP were asked for their subjective evaluation of the focus groups. Rates of sickness absence were taken from the routine data of the employer.
Results: Participants of the OHMP indicated that they had learned better ways of coping and communication and that they had generated specific intentions to make changes in their working situation. The rate of sickness absence in the intervention group decreased from 9.26% in the year before the OHMP to 7.93% in the year after the program, i.e. by 14.4%, while there was an increase of 7.9% and 10.7% in the two control groups.
Conclusions: The data suggest that OHMP with focus on self-efficacy and self management of individuals and teams are helpful in reducing work absenteeism.

description: Gallai's path decomposition conjecture states that if $G$ is a connected graph on $n$ vertices, then the edges of $G$ can be decomposed into at most $\lceil \frac{n }{2} \rceil$ paths. A graph is said to be an odd semi-clique if it can be obtained from a clique on $2k+1$ vertices by deleting at most $k-1$ edges. Bonamy and Perrett asked if the edges of every connected graph $G$ on $n$ vertices can be decomposed into at most $\lfloor \frac{n}{2} \rfloor$ paths unless $G$ is an odd semi-clique. A graph $G$ is said to be 2-degenerate if every subgraph of $G$ has a vertex of degree at most $2$. In this paper, we prove that the edges of any connected 2-degenerate graph $G$ on $n$ vertices can be decomposed into at most $\lfloor \frac{n }{2} \rfloor$ paths unless $G$ is a triangle.

description: We consider a large neutral atom of atomic number $Z$, modeled by a pseudo-relativistic Hamiltonian of Chandrasekhar. We study its suitably rescaled one-particle ground state density on the Thomas--Fermi length scale $Z^{-1/3}$. Using an observation by Fefferman and Seco (1989), we find that the density on this scale converges to the minimizer of the Thomas--Fermi functional of hydrogen as $Z\to\infty$ when $Z/c$ is fixed to a value not exceeding $2/π$. This shows that the electron density on the Thomas--Fermi length scale does not exhibit any relativistic effects.

description: The purpose of this study is to assess the effect of different dimensions of school climate on the academic performance of students in a school in Kinshasa, DRCongo. A school climate rating scale was administered to a non-probabilistic sample of 138 students in grades 5 and 6 of the school's humanities. Academic performance was obtained from the first semester point scores of the 2019-2020 school year. The results of the study indicate a positive evaluation of school climate by the study subjects. In terms of academic performance, the subjects have average quality scores. The regression analysis revealed the non-influence of different dimensions of school climate on the academic performance of the study subjects.

On Minimization and Learning of Deterministic $ω$-Automata in the Presence of Don't Care Words

description: We study minimization problems for deterministic $ω$-automata in the presence of don't care words. We prove that the number of priorities in deterministic parity automata can be efficiently minimized under an arbitrary set of don't care words. We derive that from a more general result from which one also obtains an efficient minimization algorithm for deterministic parity automata with informative right-congruence (without don't care words).
 We then analyze languages of don't care words with a trivial right-congruence. For such sets of don't care words it is known that weak deterministic Büchi automata (WDBA) have a unique minimal automaton that can be efficiently computed from a given WDBA (Eisinger, Klaedtke 2006). We give a congruence-based characterization of the corresponding minimal WDBA, and show that the don't care minimization results for WDBA do not extend to deterministic $ω$-automata with informative right-congruence: for this class there is no unique minimal automaton for a given don't care set with trivial right congruence, and the minimization problem is NP-hard. Finally, we extend an active learning algorithm for WDBA (Maler, Pnueli 1995) to the setting with an additional set of don't care words with trivial right-congruence.

description: Reptation governs motion of long polymers through a confining environment. Slack enters at the ends and diffuses along the polymer as stored length. The rate at which stored length diffuses limits the speed at which the chain can drift. This paper relates the rate of stored length diffusion to the conformation of the tube within which the polymer is confined. In the scaling limit of long polymer chains and weak applied electric fields, holding the product of polymer length times field finite, the tube length and stored length density take on their zero-field values. The drift velocity then depends only on the the polymer's end-to-end separation in the direction of the field.

description: In time Petri nets (TPNs), time and control are tightly connected: time measurement for a transition starts only when all resources needed to fire it are available. Further, upper bounds on duration of enabledness can force transitions to fire (this is called urgency). For many systems, one wants to decouple control and time, i.e. start measuring time as soon as a part of the preset of a transition is filled, and fire it after some delay \underline{and} when all needed resources are available. This paper considers an extension of TPN called waiting nets that dissociates time measurement and control. Their semantics allows time measurement to start with incomplete presets, and can ignore urgency when upper bounds of intervals are reached but all resources needed to fire are not yet available. Firing of a transition is then allowed as soon as missing resources are available. It is known that extending bounded TPNs with stopwatches leads to undecidability. Our extension is weaker, and we show how to compute a finite state class graph for bounded waiting nets, yielding decidability of reachability and coverability. We then compare expressiveness of waiting nets with that of other models w.r.t. timed language equivalence, and show that they are strictly more expressive than TPNs.

description: In this paper, we study heliospheric Ly-$α$ absorption toward nearby stars in different lines of sight. We use the Baranov-Malama model of the solar wind interaction with a two-component (charged component and H atoms) interstellar medium. Interstellar atoms are described kinetically in the model. The code allows us to separate the heliospheric absorption into two components, produced by H atoms originating in the hydrogen wall and heliosheath regions, respectively. We study the sensitivity of the heliospheric absorption to the assumed interstellar proton and H atom number densities. These theoretical results are compared with interstellar absorption toward six nearby stars observed by the Hubble Space Telescope.

description: We present UV spectra of the protoplanetary nebula (pPN) Hen3-1475 obtained with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope (HST). Our deep, low-dispersion spectroscopy enables monochromatic imaging of Hen3-1475 in UV nebular emission lines, the first of such attempt ever made for a pPN. The high spatial resolution of STIS imaging allows an unprecedentedly sharp view of the S-shaped jet, especially the inner NW1 knot, which is resolved into four components in the MgII 2800 line emission. Through critical comparison with HST optical narrowband images, we found a negative radial velocity gradient in NW1, from -1550 km/s on its innermost component to about -300 km/s on the outermost. Despite their high radial velocities, these components of NW1 mostly show no obvious (or very small) proper motions, indicating that they might be quasi-stationary shocks near the tip of the conical flow along the collimated jet of Hen3-1475.

Barriers in fostering critical thinking in higher distance education: faculty members’ perceptions

description: Nowadays, the central role of Critical Thinking (CT) in Higher Education is a fundamental educational priority and its fostering in courses is a fundamental major concern that underpins contemporary educational approaches, both in conventional (face-to-face) and Distance Education (DE). However, literature has highlighted several barriers that prevent the fostering of CT, which concern faculty, students, higher education institutions, and the educational methodologies they apply. While such barriers have been explored mainly in face-to-face education, their systematic detection in DE environments is limited. In an attempt to fill this gap, the present study conducted a qualitative research design regarding the perceptions of tutors who are employed in DE courses of the Hellenic Open University (HOU) about the factors that hinder the fostering of CT. The findings showed that the most important barrier which is related to tutors themselves is the lack of training in CT. Concerning students, their stereotypes, worldviews, busy schedules, and lack of motives and expectations, act as deterrents to any attempt toward CT. Regarding the implementation of DE, tutors pointed out several communication barriers they face, being away from students.

description: With the growing consensus on simple power law inflation models not being favored by the PLANCK observations, dynamics for the non-standard inflation gain significant interest in the recent past. In this paper, we analyze in detail a class of supergravity inspired phenomenological inflationary models with non-polynomial potential based on Maity (Nucl.Phys. B919 (2017) 560), and compare the model predictions with the currently most favored Starobinsky and its generalized $α$-attractor models in the ($n_s$ , $r$) plane constrained by PLANCK. Importantly for a wide range of parameter space, our model provides successful inflation in the sub-Planckian regime. We also have performed model independent analysis of reheating in terms of the effective equation of state parameter. In particular, we consider two stages of reheating dynamics with generalized inflaton equation of state in the initial and relativistic equation of state in the later phase. Finally, we show how our generalized reheating analysis constrains the inflation models under consideration

description: We study how the singular behaviour of classical systems at bifurcations is reflected by their quantum counterpart. The semiclassical contributions of individual periodic orbits to trace formulae of Gutzwiller type are known to diverge when orbits bifurcate, a situation characteristic for systems with a mixed phase space. This singular behaviour is reflected by the quantum system in the semiclassical limit, in which the individual contributions remain valid closer to a bifurcation, while the true collective amplitude at the bifurcation increases with some inverse power of Planck's constant (with an exponent depending on the type of bifurcation). We illustrate the interplay between the two competing limits (closeness to a bifurcation and smallness of $\hbar$) numerically for a generic dynamical system, the kicked top.

This is understood in the weak-Kondo-coupling limit of the Heisenberg-Kondo lattice model by bosonization and in the strong-coupling limit by a mapping to a modified t-J model. Only for certain ranges of filling and Heisenberg coupling does the spin gap phase extend from weak to strong coupling.

Subject Access to Museum Objects: Applying the Principles of the Subject Approach to Information from Library and information Science to the Documentation of Humanities Museum Collections
Creators: name: Shubert, Steven Blake
Publisher: name: Zenodo
Year: 2019
Subjects: subject: https://www.isko.org/kolit.php?cl=878

description: This thesis investigates the extent to which the principles of subject access as developed within library and information science may be applied to the problem of indexing and classifying museum objects. It begins with a review of events concerning museum registration, documentation, and cataloguing that have contributed to the development of subject access during the second half of the twentieth century in Great Britain, the United States and Canada. An investigation of subject access to objects in humanities museum collections is then conducted according to a paradigm for the subject approach to information developed from the literature of library and information science. This paradigm consists of four fundamental elements: 1) the philosophical and abstract conception of subject content in contrast to descriptive or identifying elements; 2) the process of conceptual analysis in order to determine subject content; 3) the representation of these concepts in a documentary language; and 4) the process of facet analysis whereby the concepts of a subject are categorized according to different characteristics of division within a domain. An explanation for subject access to humanities museum objects in abstract or philosophical terms is developed from Shannon's model of information transfer and the work of theorists in art and museology concerning the levels of meaning in art and museum objects. Subject representations in cataloguing records from humanities databases of the Canadian Heritage Information Network are examined to determine the concepts on which they were based and to see if these concepts varied amongst the disciplines of ethnology, history and art. Documentary languages constructed to regularize subject access to museum objects are also analysed according to these same three disciplines. The findings demonstrate the relevance of the type of conceptual analysis and representation of concepts in documentary languages found in library and information science to the museum environment. Facet analysis is also shown to provide access to multiple object characteristics through an examination of the Art & Architecture Thesaurus as applied to museum objects.

Of the 32 systems in the final sample, 11 systems have been discovered by the Hipparcos satellite. The combined spatial density is evaluated at (1.02+/-0.24)x10^-5 pc^-3. The Relative Frequency of Occurrence (RFO), defined in relation to the Main Sequence stars, depends on the luminosity. An assumption of RFO~1/500 for MV>+1.5 is consistent with the data, although the number statistics is poor with the resulting uncertainty in the spatial density and the RFO by a factor of about two. The RFO rapidly decreases for brighter binaries to a level of 1/5,000 for MV

description: Midrash collections are complex rabbinic works that consist of text in multiple languages, which evolved through long processes of unstable oral and written transmission. Determining the origin of a given passage in such a compilation is not always straightforward and is often a matter of dispute among scholars, yet it is essential for scholars' understanding of the passage and its relationship to other texts in the rabbinic corpus. To help solve this problem, we propose a system for classification of rabbinic literature based on its style, leveraging recent advances in natural language processing for Hebrew texts. Additionally, we demonstrate how this method can be applied to uncover lost material from a specific midrash genre, Tan\d{h}uma-Yelammedenu, that has been preserved in later anthologies.
Domain wall between the Dirac sea and the "anti-Dirac sea"

description: It was shown in work \cite{vergeles2021note} that in the theory of gravity coupled with the Dirac field, each state $|λ\rangle$ has its own twin $|λ;PT\rangle$, which is obtained by a discrete PT transformation. If in the state $|λ\rangle$ the Dirac sea is filled, then in the state $|λ;PT\rangle$ there is an "anti-Dirac" filling (in terms of the state $|λ\rangle$). It is important that the energies of these states are the same. Therefore, there may be domains with different filling of the Dirac sea. Here we study a domain wall connecting two such adjacent domains.

description: Etwa 60% der Patienten in der psychosomatischen Rehabilitation kommen mit arbeitsplatzbezogenen Ängsten und Problemen. Aber auch in der ambulanten Praxis findet man unter Patienten mit chronischen psychischen Erkrankungen etwa 10%, die ihrem Arbeitsplatz mit phobischem Vermeidungsverhalten gegenüberstehen und häufig in einer Langzeitarbeitsunfähigkeit stecken (Muschalla & Linden 2013).
Herauszufinden, was bei diesen Patienten das Problem ist, ist eine unabdingbare Voraussetzung um einen passenden Behandlungsansatz zu finden.
From Attention to Distraction to Attention: Considering an ADD Anthropology

Publisher: name: Monash University

Subjects: Uncategorized

description: This essay draws from a contemporary turn in anthropological theory that calls for a shift in scholarly attention away from well-defined subjects of study, towards the interwoven networks of life on earth. I reflect on some of my own ethnographic experiences in the field, and the ways in which my mind and body wandered away from my bounded field-site to consider wider ecologies, and the cosmos at large. Reaching back into my own childhood, I reflect on the politics of socializing children in western society to 'pay attention' to the human world, and avoid being 'distracted' by the biological context of life on earth. To me, this is a tragic fallacy based on a simple conflation between attention and distraction. I invite anthropologists to consider the merits of doing fieldwork with a child-like attentiveness to life at large to ensure that they remain properly distracted from the normative theoretical and methodological constructs of the ethnographic endeavour.

title: Negative work perception not changed in a short work-anxiety-coping group therapy intervention
Creators: name: Muschalla, Beate
Publisher: name: Taylor & Francis
Year: 2016
Subjects: subject: Workplace, mental health, anxiety, sick-leave, work-oriented interventions
subject: 150

description: Background:
Work-anxiety is disabling and often associated with long-term sick leave. Early intervention is therefore necessary. Work-anxieties are associated with a negative work perception. Therefore one aim in early intervention is a cognitive reframing of dysfunctional perceptions of workplace characteristics.
Methods:
A psychotherapeutic specialist conducted two group programs of four sessions each. One hundred twenty-three rehabilitation inpatients with work-anxieties were randomly assigned either to a work-anxiety-coping group or to a recreational group. The Short Questionnaire for Work Analysis (KFZA) was administered before and after the group treatment to measure perceptions of working conditions.
Results:
Participants from the work-anxiety-coping-group did not see their work in a significantly more positive light at the end of the intervention compared to participants from the recreational group (interaction of repeated measurement * intervention: p= .177 – .971, Cohen´s d for comparison of change from beginning to the end of rehabilitation = 0.00 – 0.23).
Conclusions:
A short work-anxiety-coping-group did not initiate a consistent positive re-appraisal of work in this study population. Employers and occupational physicians should not expect positive changes of work perception when an employee returns from short medical rehabilitation, even in cases in which work-directed treatment was completed. Additional support from the workplace must be considered, e.g. employer-physician-employee-conversation preceding return to work, or (temporary) work adjustment. The aim should be to overcome return to work-barriers in the form of negative work perception.

description: This article gives an elementary review of gravitational collapse and the cosmic censorship hypothesis. Known models of collapse resulting in the formation of black holes and naked singularities are summarized. These models, when taken together, suggest that the censorship hypothesis may not hold in classical general relativity. The nature of the quantum processes that take place near a naked singularity, and their possible implication for observations, is briefly discussed.

Open charm measurements in NA61/SHINE at CERN SPS
Creators: name: Staszel, Pawel

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The measurements of open charm production was proposed as an important tool to investigate the properties of hot and dense matter formed in nucleus-nucleus collisions as well as to provide the means for model independent interpretation of the existing data on $\text{J}/ψ$ suppression. Recently, the experimental setup of the NA61/SHINE experiment was supplemented with a Vertex Detector which was motivated by the importance and the possibility of the first direct measurements of open charm meson production in heavy ion collisions at SPS energies. First test data taken in December 2016 on Pb+Pb collisions at 150$A$ GeV/$c$ allowed to validate the general concept of D$^0$ meson detection via its D$^0 \to π^+ + K^-$ decay channel and delivered a first indication of open charm production. The physics motivation of open charm measurements at SPS energies, pilot results on open charm production, and finally, the future plans of open charm measurements in the NA61/SHINE experiment after LS2 are presented.

description: The study of strings is an important combinatorial field that precedes the digital computer. Strings can be very long, trillions of letters, so it is important to find compact representations. Here we first survey various forms of one potential compaction methodology, the cover of a given string x, initially proposed in a simple form in 1990, but increasingly of interest as more sophisticated variants have been discovered. We then consider covering by a seed; that is, a cover of a superstring of x. We conclude with many proposals for research directions that could make significant contributions to string processing in future.
Exploring early graders’ preconceptions about air within non-formal settings

Publisher: name: Mediterranean Journal of Education
Year: 2023
Subjects: Preconceptions, air, Archaeological Museum of Ioannina, pre-causal thinking

description: The present paper is a meta-analysis of the implementation of the science education program “Thunderbolt hunt” at the Archaeological Museum of Ioannina. During this program students approach the concept of air through play-based actions. The goal of the paper is to explore first and second-grade primary students’ preconceptions about air and to classify them according to Laurandeau and Pinard’s categorization. Based on the results, students’ preconceptions about air are consistent with the literature’s, highlighting the importance of identifying and addressing students’ preconceptions in organized context. The present paper demonstrates students’ readiness to work on their preconceptions developing precursor models and moving from the everyday concepts towards more scientific.

title: Asking for work adjustments or initiating behavioral changes – what makes a “problematic co-worker” score Brownie points?: An experimental study on the reactions towards colleagues with a personality disorder

description: People with mental disorders, especially personality disorders, often face low acceptance at work. This is particularly problematic when returning to work after sick-leave, because it impedes reintegration into the former workplace. This study explores colleagues’ reactions towards a problematic worker dependent on the returning person’s reintegration strategy: The returning person undertaking changes in their behaviour is compared with the person requesting adjustments of the workplace. In an experimental study 188 employed persons read one of four vignettes that described a return-to-work-situation of a problematic co-worker. Across all vignettes the co-worker was depicted as having previously caused problems in the work team. In the first vignette the co-worker asked for workplace-adjustments when she returned to work; in the second, she attempted to change her behaviour in order to cause less problems; the third vignette combined both workplace-adjustments and behavioural changes; and the fourth (control) vignette did not include any change. Study participants were asked for their reactions towards the problematic co-worker. Vignettes that included a behavioural change evoked more positive reactions towards the co-worker than vignettes without any behavioural change. Asking for workplace-adjustments alone did not yield more positive reactions compared to not initiating any change. When preparing employees with interactional problems for their return to work, it is not effective to only instruct them on their statutory entitlement for workplace-adjustments. Instead, it is advisable to encourage them to proactively strive for behaviour changes.

description: Photoemission spectra of Bi_2Sr_2CaCu_2O_{8+delta} below T_c show two features near the (pi,0) point of the zone: a sharp peak at low energy and a higher binding energy hump. We find that the sharp peak persists at low energy even as one moves towards (0,0), while the broad hump shows significant dispersion which correlates well with the normal state dispersion. We argue that these features are naturally explained by the mixing of electrons with a bosonic mode which appears only below T_c, and speculate that the latter may be related to the resonance seen in recent neutron data.
