description: The current research on hosts’ perceptions of tourism has focused on survey-based studies, proving their heterogeneity at the moment of the study, but lacking to present any evolution over time. This paper aims to show if, and how, hosts’ public narratives of tourism have changed in the particular case of the city of Barcelona (Spain) from 2004 to 2015, analyzing any common and opposing points of their argumentation as they may change over time. These narratives represent the perspectives of two opposing groups of hosts: residents and destination management organizations (DMOs). We used thematic analysis to portray their public discourse, as expressed in the residents’ magazine Carrer, and the annual reports of Turisme de Barcelona. Through the analysis of common and opposing points of their argumentation, our findings show a clear division between the residents’ tourism-phobic perception and the DMO’s tourism-philic one, which appears to change their structure over time, going from complete opposites to searching for common ground when tourism is addressed as part of the city’s identity by both sides.

description: Temporal sequences of satellite images constitute a highly valuable and abundant resource for analyzing regions of interest. However, the automatic acquisition of knowledge on a large scale is a challenging task due to different factors such as the lack of precise labeled data, the definition and variability of the terrain entities, or the inherent complexity of the images and their fusion. In this context, we present a fully unsupervised and general methodology to conduct spatio-temporal taxonomies of large regions from sequences of satellite images. Our approach relies on a combination of deep embeddings and time series clustering to capture the semantic properties of the ground and its evolution over time, providing a comprehensive understanding of the region of interest. The proposed method is enhanced by a novel procedure specifically devised to refine the embedding and exploit the underlying spatio-temporal patterns. We use this methodology to conduct an in-depth analysis of a 220 km$^2$ region in northern Spain in different settings. The results provide a broad and intuitive perspective of the land where large areas are connected in a compact and well-structured manner, mainly based on climatic, phytological, and hydrological factors.

description: We study the emergence of Boltzmann's law for the "single particle energy distribution" in a closed system of interacting classical spins. It is shown that for a large number of particles Boltzmann's law may occur, even if the interaction is very strong. Specific attention is paid to classical analogs of the average shape of quantum eigenstates and "local density of states", which are very important in quantum chaology. Analytical predictions are then compared with numerical data.

description: Background: Workplace-related anxieties are often connected with sick leave. There are no established instruments which allow to assess this phenomenologically heterogeneous group of disorders.
Method: 132 psychosomatic inpatients were interviewed with a standardized diagnostic interview in respect to mental illnesses, especially primary anxiety disorders, and in addition in respect to different work-related anxiety disorders.
Results: 71% of women and 54% of men complained about work-related anxiety. 20.5% of participants are suffering from work-related panic, 58% from work-related phobia, 34.1% from work-related social phobia, 39.4% from work-related generalized anxiety, and 1.5% from work-related PTSD. There is a moderate relation between mental disorders or primary anxiety disorders and work-related anxiety. 14% of the participants did only suffer from workplace-related anxiety and did not report any other anxiety disorder outside the workplace situation.
Conclusion: There are various types of workplace-related anxieties. They are partly independent clinical phenomena deserving special diagnostic and therapeutic attention.

description: Helical magnets which violated space inversion symmetry have rather peculiar topological defects. In isotropic helical magnets with exchange and Dzyaloshinskii-Moriya interactions there are only three types of linear defects: $\pmπ$ and $2π$-disclinations. Weak crystal anysotropy suppresses linear defects on large scale. Instead planar defects appear: domain walls that separate domains with different preferential directions of helical wave vectors. The appearance of such domain walls in the bulk helical magnets and some of their properties were predicted in the work \cite{Li 2012}. In a recent work by an international team of experimenters and theorists \cite{Schoenherr 2018} the existence of new types of domain walls on crystal faces of helical magnet FeGe was discovered. They have many features predicted by theory \cite{Li 2012}, but display also unexpected properties, one of them is the possibility of arbitrary angle between helical wave vectors. Depending on this angle the domain walls observed in \cite{Schoenherr 2018} can be divided in two classes: smooth and zig-zag. This article contains a mini-review of the existing theory and experiment. It also contains new results that explain why in a system with continuos orientation of helical wave vectors domain walls are possible. We discuss why and at what conditions smooth and zig-zag domain walls appear, analyze spin textures associated with helical domain walls and find the dependence of their width on angle between helical wave vectors.

description: Programs with a continuous state space or that interact with physical processes often require notions of equivalence going beyond the standard binary setting in which equivalence either holds or does not hold. In this paper we explore the idea of equivalence taking values in a quantale V, which covers the cases of (in)equations and (ultra)metric equations among others. Our main result is the introduction of a V-equational deductive system for linear λ-calculus together with a proof that it is sound and complete. In fact we go further than this, by showing that linear λ-theories based on this V-equational system form a category that is equivalent to a category of autonomous categories enriched over 'generalised metric spaces'. If we instantiate this result to inequations, we get an equivalence with autonomous categories enriched over partial orders. In the case of (ultra)metric equations, we get an equivalence with autonomous categories enriched over (ultra)metric spaces. We additionally show that this syntax-semantics correspondence extends to the affine setting. We use our results to develop examples of inequational and metric equational systems for higher-order programming in the setting of real-time, probabilistic, and quantum computing.

description: Hintergrund: Anpassungsstörungen kommen häufig im Zusammenhang mit dem Arbeitsplatz vor. Eine besondere Rolle spielen arbeitsplatzbezogene Ängste, da jeder Arbeitsplatz angst-auslösende Aspekte hat. Beispiele sind Möglichkeiten des Leistungsversagens, Unfälle, Bossing, Mobbing, Crowding, aggressive Kunden oder Bedrohung der Existenzsicherung. Die Arbeitsplatzsituation kann Ängste auslösen, aber auch bestehende Angsterkrankungen können zu speziellen Problemen am Arbeitsplatz führen. In dieser Untersuchung wurden die Qualität und das Ausmaß von Job-Ängsten bei Patienten mit psychischen und orthopädischen Erkrankungen untersucht.
Methode: Es wurden 90 unausgelesene Patienten einer psychosomatischer und 100 einer orthopädischen Rehabilitationsklinik mittels der Job-Angst-Skala (JAS) untersucht. Zusätzlich wurden arbeitsbezogene Merkmale mittels Selbstbericht erfasst.
Ergebnisse: Psychosomatikpatienten erreichten signifikant höhere Skalenwerte als Orthopädiepatienten. Orthopädiepatienten erleben qualitativ vor allem funktionsbezogene Ängste, im Gegensatz zu Psychosomatikpatienten, die in den Dimensionen generelle Besorgnis, Panikerleben, Existenzängste und globale Arbeitsplatzangst hohe Ausprägungen berichten. In beiden Indikationsgruppen stand das Job-Angst-Niveau in Zusammenhang mit der Arbeitsunfähigkeitsdauer.
Schlussfolgerungen: Zwischen verschiedenen Indikationsgruppen von Rehabilitationspatienten gibt es Unterschiede im quantitativen und qualitativen Erleben arbeitsplatzbezogener Ängste. dies deutet darauf hin, dass psychische Krankheit zu vermehrten Job-Ängsten führt. Gleichzeitig stellen Job-Ängste auch bei vordergründig somatischen Störungen einen wichtiger Faktor zum Verständnis von Arbeitsunfähigkeit dar, was Konsequenzen für die Diagnostik und Behandlung bei diesen Patienten haben muss.

description: Excerpts from the report Preface: This study was undertaken at the request of the city of Benton Harbor, Mich., and its Market Board. The primary objective was to determine whether the Benton Harbor Fruit Market should be remodeled on its present site or be relocated within or outside of the city. Secondary purposes were to ascertain the type and extent of facilities that should be planned for any new market, the estimated cost, operating expense, and revenue requirements of such a project, the means and method of financing it, and the savings and other benefits reasonably to be expected from realization of the proposal. Data used as the basis for necessary fact findings and conclusions were assembled by personal observation of the existing market and its operations, examination of market records and accounts, and discussion, interview, and correspondence with city and market officials, contractors, construction engineers, growers, buyers, and others in the area.
The role of the School Principal through the lenses of the dominant strategy for education

Subjects: Neoliberal politics, school principal, school organization, educational leadership, assembly

description: During the last decades, in Greece and elsewhere, there has been a sharp shift in educational systems towards privatization. This move is molded within the frame of the general neoliberal policy and its strategic choices. The aim of this paper is to present the most pivotal positions for the role of school principal, as formulated within the context of the dominant political orientation. We focus on general educational changes and on the development of a "new" vision towards a counterhegemonic realization of the educational and administrative organization of the school. This choice has been made from the perspective of a variety of theoretical prerequisites and pedagogical views, leaving the context of school legislation and the role of executives at the margins of the debate. Finally, we look at the possibilities of formulating an alternative proposal for the teacher and the organisational structure of the school. More specifically, we focused on a number of issues pertaining the role of the school principal and the role of the teaching staff, the decision making process, the social interactions within the school environment, the principles of educational planning and the deployment of the education endeavor within the context of neoliberal strategies. The critical aspect we are arguing for is the interconnection of the internal dynamics of an organizational structure with the external forces. The concept of relative autonomy here is intertwined with the concept of 'pedagogical leadership'. We believe this relationship is the key to answering the central question we have posed, since the "new" educational policy is founded on decentralization through school self-administration, on expanding the exercise of leadership of school principals, on increasing the pressure for assessment and accountability and on the transition of managerial duties from management level to demanding, "high" duties. In conclusion, to the functional patterns for school politics and to the role of the leader, we counter propose the need for the formulation of a more comprehensive response to the school social mission alongside with the collective empowerment of teachers.

description: Cancer is a multi-origin collection of diseases attributed by abnormal and uncontrolled cell growth spread from origin to other parts of body eventually leading to death. After decades of research, anticancer drug therapy is still very much limited to inhibiting growth and controlling the spread of tumour cells. Finding novel molecular targets and drug candidates using assimilation of experimental and computational approaches is among the recent strategies adopted by researchers to speed up the anticancer drug discovery process. In present study, synthesis of 40 novel substituted 5-aryl-2-oxo-/thioxo-2,3-dihydro-1H-benzo[6,7]chromeno[2,3-d]pyrimidine-4,6,11(5H)-triones has been accomplished followed by molecular target identification using different in silico approaches. The target prioritization methodology involved identification and selection of targets, molecular docking followed by molecular dynamic simulation and determination of binding free energy using MM-GBSA technique. Systematic and stepwise virtual screening of biological targets lead to identification of B-cell lymphoma 6 protein (BCL6), lysine-specific histone demethylase 1 A (LSD1), nuclear factor kappa-light-chain-enhancer of activated B cells (NFkB P65) and poly (ADP-ribose) polymerase 1 (PARP1) as suitable anticancer targets for the set of synthesized compounds.

description: We extend the classical integrability of the CGHS model of 2d dilaton gravity [1] to a larger class of models, allowing the gravitational part of the action to depend more generally on the dilaton field and, simultaneously, adding fermion- and U(1)-gauge-fields to the scalar matter. On the other hand we provide the complete solution of the most general dilaton-dependent 2d gravity action coupled to chiral fermions. The latter analysis is generalized to a chiral fermion multiplet with a non-abelian gauge symmetry as well as to the (anti-)self-dual sector df = *df (df = -*df) of a scalar field f.

description: We take the testing perspective to understand what the minimal discrimination time between two stimuli is for different types of rate coding neurons. Our main goal is to describe the testing abilities of two different encoding systems: place cells and grid cells. In particular, we show, through the notion of adaptation, that a fixed place cell system can have a minimum discrimination time that decreases when the stimuli are further away. This could be a considerable advantage for the place cell system that could complement the grid cell system, which is able to discriminate stimuli that are much closer than place cells.

description: New Zealand is a world leader in the use of Individual Transferable Quota (ITQ) to manage fisheries. Although the use of an ITQ system is not unique to New Zealand, no other country has used this system to the same extent as New Zealand. This has meant that, internationally, a lot of interest has been placed on how our system works and the level of success it has achieved. Generally, the New Zealand system is considered to be a success story, yet the system has changed a number of times since its inception in 1986. Despite the level of interest in New Zealand’s unique ITQ system, the current literature is unable to provide a complete account of the historic and current regulations surrounding it. This paper addresses this gap by documenting how the Quota Management System (QMS) functions and the changes it has undergone since its introduction. Reviewing these changes facilitates a deeper understanding of the system itself, as well as providing insight into its potential limitations.

description: Virtual Reality (VR) for Serious Games (SGs) is attracting increasing attention for training applications due to its potential to provide significantly enhanced learning to users. Some examples of the application of VR for SGs are complex training evacuation problems such as indoor earthquake evacuation or fire evacuation. The indoor 3D geometry of existing buildings can largely influence evacuees' behaviour, being instrumental in the design of VR SGs storylines and simulation scenarios. The VR scenarios of existing buildings can be generated from drawings and models. However, these data may not reflect the 'as-is' state of the indoor environment and may not be suitable to reflect dynamic changes of the system (e.g. Earthquakes), resulting in excessive development efforts to design credible and meaningful user experience. This paper explores several workflows for the rapid and effective reconstruction of 3D indoor environments of existing buildings that are suitable for earthquake simulations. These workflows start from Building Information Modelling (BIM), laser scanning and 360-degree panoramas. We evaluated the feasibility and efficiency of different approaches by using an earthquake-based case study developed for VR SGs.

description: Modern kindergarten classes are highly diverse. This poses the challenge of the productive use of diversity namely the way students with different biographies (lifeworlds) can understand, learn from, and coexist with “others”. Familiarity with diverse biographies is important quality in the learning process as these capture aspects of student diversity that give individual meaning to self-existence. Moreover, biographical narratives in flexible intercultural communicative environments make possible to identify students’ starting points (pre-existing knowledge), learning readiness and cultural characteristics that compose identity. Thus, the negotiation of these points in the form of biographical reflections in a dialogical context can expand the understanding of the self, and the "other" as well as form a coherent view about modern world. The output of negotiating and communicating multiple biographical experiences, perspectives, and collaborative intelligence, is a newly generated intercultural learning. This article presents the role of preschool student biographies in cultivating intercultural learning. In this account, diversity is considered both as a learning resource and a learning opportunity.

description: We report on the combined X-ray and radio observations of the type Ic SN 2002ap, using XMM-Newton ToO observation of M74 and the Giant Metrewave Radio Telescope (GMRT). We account for the presence of a nearby source in the pre-supernova Chandra field of view in our measurements of the X-ray flux (0.3 - 10 KeV) 5.2 days after the explosion. The X-ray spectrum is well fitted by a power law spectrum with photon index $α= 2.6$. Our results suggest that the prompt X-ray emission originates from inverse Compton scattering of photospheric thermal emission by energetic electrons. Radio observations with the GMRT at 610 MHz (8 days after the explosion) and 1420 MHz (70 days after the explosion) are combined with the high frequency VLA observations of SN 2002ap reported earlier, and the early radiospheric properties of SN 2002ap are compared with similar data from two other supernovae. Finally, the GMRT radio map reveals four other X-ray sources in the field of view of M74 with radio counterparts.

description: The didactic transposition of scientific concepts into school curricula is most often carried out after a relatively long period. To this problem we add those of the updating of these concepts and the pedagogical approaches used. In this work, we aim to identify the pedagogical styles used to teach scientific knowledge and its state relatively to research news, at the secondary cycle in Tunisia as part of the discipline of Life and Earth Sciences (LES). Thus, we have analysed from these sides, the theme “Organism immunity” in the current LES textbooks of the 1st secondary year, common trunk, and the 4th secondary year (end term classes), Experimental Sciences section in Tunisia. The dephasing of the knowledge taught in relation to the actuality of the research on the one hand, and the nature of the styles chosen in the learning activities on the other hand, are likely to negatively affect the quality of science learning and do not engage the student in a process of democratization of knowledge acquisition.

description: Linear Temporal Logic (LTL) is one of the most popular temporal logics, that comes into play in a variety of branches of computer science. Among the various reasons of its widespread use there are its strong foundational properties: LTL is equivalent to counter-free omega-automata, to star-free omega-regular expressions, and (by Kamp's theorem) to the First-Order Theory of Linear Orders (FO-TLO). Safety and co-safety languages, where a finite prefix suffices to establish whether a word does not belong or belongs to the language, respectively, play a crucial role in lowering the complexity of problems like model checking and reactive synthesis for LTL. SafetyLTL (resp., coSafetyLTL) is a fragment of LTL where only universal (resp., existential) temporal modalities are allowed, that recognises safety (resp., co-safety) languages only. The main contribution of this paper is the introduction of a fragment of FO-TLO, called SafetyFO, and of its dual coSafetyFO, which are expressively complete with respect to the LTL-definable safety and co-safety languages. We prove that they exactly characterize SafetyLTL and coSafetyLTL, respectively, a result that joins Kamp's theorem, and provides a clearer view of the characterization of (fragments of) LTL in terms of first-order languages. In addition, it gives a direct, compact, and self-contained proof that any safety language definable in LTL is definable in SafetyLTL as well. As a by-product, we obtain some interesting results on the expressive power of the weak tomorrow operator of SafetyLTL, interpreted over finite and infinite words. Moreover, we prove that, when interpreted over finite words, SafetyLTL (resp. coSafetyLTL) devoid of the tomorrow (resp., weak tomorrow) operator captures the safety (resp., co-safety) fragment of LTL over finite words.

description: We consider the tunneling of a wave packet through a potential barrier which is coupled to a nonintegrable classical system and study the interplay of classical chaos and dissipation in the tunneling dynamics. We show that chaos-assisted tunneling is further enhanced by dissipation, while tunneling is suppressed by dissipation when the classical subsystem is regular.

Mathematics tutors' views on benefits and challenges of using Algebra tiles in teaching linear equations in one variable
Creators: name: SALIFU, ANAS SEIDU
Publisher: name: Mediterranean Journal of Education
Year: 2022
Subjects: Algebra tiles, benefits, challenges, college Mathematics teachers

description: This study examines the views of mathematics tutors on the benefits and challenges of using algebra tiles in solving linear equations with one variable. The qualitative research paradigm was used with a case study design. The sampling technique used was purposive with four mathematics tutors as the sample. The instrument was semi-structured open-ended interview guides. The findings revealed, among others, that the benefits of algebra tiles in solving linear equations with one variable includes (1) helping students to distinguish between coefficients and constant values, (2) the best way for teachers to explain the neutralization of equal positive and negative values. While some of the challenges of algebra tiles are (1) teachers lack the knowledge to use the algebra tiles, (2) non- availability, and inadequacy of algebra tiles.

description: I present two examples in which the curvature singularity of a radiation-dominated Universe is regularized by (a) the repulsive effects of spin interactions, and (b) the repulsive effects arising from a breaking of the local gravitational gauge symmetry. In both cases the collapse of an initial, asymptotically flat state is stopped, and the Universe bounces towards a state of decelerated expansion. The emerging picture is typical of the pre-big bang scenario, with the main difference that the string cosmology dilaton is replaced by a classical radiation fluid, and the solutions are not duality-invariant.

description: This study examined teachers’ citizenship behaviour as determinant of students’ academic performance in North-central, Nigeria. The study adopted a descriptive research design of correlation type with a population of 2114 Principals, and 5728 Vice Principals in North-central, Nigeria. The target population comprised 977 principals and 2454 vice principals in the sampled States. Random sampling technique was used to select three (Kwara, Kogi Nassarawa) out of the entire six states in the geopolitical zone. Proportional sample technique was used to select 598 participants as respondents of the study. Relevant data were collected for the study through the questionnaire tagged “Teachers’ Citizenship Behaviour Questionnaire (TCBQ)”. The findings of the study revealed that teachers’ citizenship behaviour influences students’ academic performance in North-central, Nigeria. Based on the findings of the study, it was recommended among others that the school administrators should expose their staff to the importance of TCB towards enhancing students’ academic performance. Also, government should organize trainings, workshops, seminars and conferences for the supervisors, principals and teachers of schools on TCB to serve as a motivational strategy for effective service delivery.

description: A simple theory of the fluid state of a charged colloidal suspension is proposed. The full free energy of a polyelectrolyte solution is calculated. It is found that the counterions condense onto the polyions forming clusters composed of one polyion and n counterions. The distribution of cluster sizes is determined explicitly. In agreement with the current experimental and Monte Carlo results, no liquid-gas phase separation was encountered.

Combinatorial formulas for shifted dual stable Grothendieck polynomials

description: The $K$-theoretic Schur $P$- and $Q$-functions $GP_λ$ and $GQ_λ$ may be concretely defined as weight generating functions for semistandard shifted set-valued tableaux. These symmetric functions are the shifted analogues of stable Grothendieck polynomials, and were introduced by Ikeda and Naruse for applications in geometry. Nakagawa and Naruse specified families of dual $K$-theoretic Schur $P$- and $Q$-functions $gp_λ$ and $gq_λ$ via a Cauchy identity involving $GP_λ$ and $GQ_λ$. They conjectured that the dual power series are weight generating functions for certain shifted plane partitions. We prove this conjecture. We also derive a related generating function formula for the images of $gp_λ$ and $gq_λ$ under the $ω$ involution of the ring of symmetric functions. This confirms a conjecture of Chiu and the second author. Using these results, we verify a conjecture of Ikeda and Naruse that the $GQ$-functions are a basis for a ring.

description: We report on Chandra ACIS-S observations of five type I X-ray bursters with low persistent emission: SAX J1324.5-6313, SAX J1752.3-3128, SAX J1753.5-2349, SAX J1806.5-2215 and SAX J1818.7+1424. We designate candidate persistent sources for four X-ray bursters. All candidates are detected at a persistent luminosity level of 10^(32-33) erg/s, comparable to soft X-ray transients in quiescence. From the number of bursters with low persistent emission detected so far with the Wide Field Cameras, we estimate a total of such sources in our Galaxy between 30 and 4000.

title: Workplace Phobia: A first explorative study on its relation to established anxiety disorders, sick leave, and work-directed treatment
Creators: name: Muschalla, Beate
name: Linden, Michael
Publisher: name: Taylor & Francis
Year: 2009
Subjects: subject: Workplace phobia, anxiety disorders, sick leave, return to work, work ability, participation disorders
subject: 150

description: Objective:
Workplace phobia is defined as a phobic anxiety reaction with symptoms of panic occurring when thinking of or approaching the workplace. People suffering from workplace phobia regularly avoid confrontation with the workplace and are often on sick leave. The specific characteristics of workplace phobia are investigated empirically in comparison to established anxiety disorders.
Method:
230 patients from an inpatient psychosomatic rehabilitation hospital were interviewed concerning workplace phobia and established anxiety disorders. Additionally, the patients filled in self-rating questionnaires on general and workplace phobic symptom load. Subjectively perceived degree of work load, sick leave and therapy participation were assessed.
Results:
Participants with workplace phobia reached significantly higher scores in workplace phobia self-rating than did participants with established anxiety disorders. A similar significant difference was not found concerning the general psychosomatic symptom load. Workplace phobics were more often on sick leave than patients with established anxiety disorders.
Conclusions:
Workplace phobia can occur as an alonestanding anxiety disorder. It has an own clinical value due to its specific consequences for work participation. Workplace phobia requires special therapeutic attention and treatment instead of purely “sick leave” certification.

description: A relation between the Schroedinger wave functional and the Clifford-valued wave function which appears in what we call precanonical quantization of fields and fulfills a Dirac-like generalized covariant Schroedinger equation on the space of field and space-time variables is discussed. The Schroedinger wave functional is argued to be the trace of the positive frequency part of the continual product over all spatial points of the values of the aforementioned wave function restricted to a Cauchy surface. The standard functional differential Schroedinger equation is derived as a consequence of the Dirac-like covariant Schroedinger equation.

description: We consider the question raised by Enciso and Peralta-Salas in [4] (see arXiv:1402.6825): What nonconstant functions $f$ can occur as the proportionality factor for a Beltrami field $\mathbf{u}$ on an open subset $U \subset \mathbb{R}^3$? We also consider the related question: For any such $f$, how large is the space of associated Beltrami fields? By applying Cartan's method of moving frames and the theory of exterior differential systems, we are able to improve upon the results given in [4]. In particular, the answer to the second question depends crucially upon the geometry of the level surfaces of $f$. We conclude by giving a complete classification of Beltrami fields that possess either a translation symmetry or a rotation symmetry.
