description: The Dieudonné crystal of a p-divisible group over a semiperfect ring R can be endowed with a window structure. If R satisfies a boundedness condition, this construction gives an equivalence of categories. As an application one obtains a classification of p-divisible groups and commutative finite locally free p-group schemes over perfectoid rings by Breuil-Kisin-Fargues modules if p>2.

description: Within each human cell, different kinds of RNA polymerases and a panoply of transcription factors bind chromatin to simultaneously determine 3D chromosome structure and transcriptional programme. Experiments show that, in some cases, different proteins segregate to form specialised transcription factories; in others they mix together, binding promiscuously the same chromatin stretch. Here, we use Brownian dynamics simulations to study a polymer model for chromosomes accounting for multiple types (“colours”) of chromatin-binding proteins. Our multi- colour model shows the spontaneous emergence of both segregated and mixed clusters of chromatin- bound proteins, depending mainly on their size, thereby reconciling the previous experimental observations. Additionally, remarkable small-world networks emerge; in these, positive and negative correlations in activities of transcription units provide simple explanations of why adjacent units in large domains are co-transcribed so often, and how one eQTL (expression quantitative trait locus) can up-regulate some genes and down- regulate others. We also explain how local genome edits induce distant omnigenic and pangenomic effects, and develop ways to predict activities of all transcription units on human chromosomes. All results point to 1D location being a key determinant of transcription, consistently with the conservation of synteny seen between rapidly-evolving enhancers and their more stable target genes. Here we provide all the scripts used for the analysis and generation of all the figures presented in the Paper.

description: This exegesis negotiates multispecies encounters and their histories in the field and the archive, and proposes birdwatching critically, animotmorphism and parafictioneering as artistic methodologies through which to decentre anthropocentrism when encountering wild urban birds. An affinity for House sparrows (Passer domesticus) forms the basis of my practice-led research. Focusing on writing by Jacques Derrida, Donna Haraway, Jose Esteban Muñoz, Elizabeth Freeman, Andre Bazin; and artworks by On Kawara, Felix Gonzalez-Torres, Pierre Huyghe, Walid Raad and Barnett Newman; I propose the ‘artist as companion’. Mobilising companion as both a noun and a verb, I counter a colonial and anthropocentric way of being in the world through a situated, queer and affirmative forms of companioning companion species.

description: We consider the determination of the finite temperature phase transition in the Yang--Mills SU(3) gauge theory. We compute the difference of the spatial and temporal energy density at a physical Wilson flow time. This difference is zero in the confined phase and becomes non zero in the deconfined phase. We locate the phase transition by using a new technique based on an exponential smoothing spline. This method is an alternative to the determination of the phase transition based on the Polyakov loop susceptibility and can also be used with dynamical fermions.

Unpacked: The collections of the University of Erlangen-Nuremberg

Subjects: University of Erlangen-Nuremberg

description: The Friedrich Alexander University of Erlangen-Nuremberg (FAU), Germany, holds about 17 scientific collections. Some of them have been established only recently, others date back to the very foundation of the university in 1743 or even have their roots in the Kunst- und Wunderkammern of the Margraves of Ansbach and Bayreuth. The collections differ not only with regard to their history, but also concerning their size, accessibility and presentation and the extent to which they are utilised for academic teaching and research. // In spite of these differences, the collections show common characteristics as well: First, they all contain three-dimensional objects which have an immense potential for the communication of science and for the representation of the university to the public. Second, the objects are all subject to fairly similar problems regarding the basic museological tasks of collecting, preserving, researching on and presenting them. // Given these shared needs and opportunities, the curators of the collections organised themselves into a working group about three years ago. As a first step, information material (leaflet, set of postcards) was published and an information platform (www.sammlungen.uni-erlangen.de) was established. In the summer term 2007, with the support of the university's administration, the working group mounted a campaign to inform the general public about the widely unknown treasures of the university’s collections. This campaign used different ways and means to achieve its aim. // This paper presents the central event of this campaign, the exhibition “Unpacked: The collections of the University of Erlangen-Nuremberg”. The project faced the problem of putting 17 collections on the scene without creating an "omnium gatherum". The paper focuses, therefore, on the concept of the exhibition. And it poses the final question "What to do next?" One answer could be the formation of a nationwide "task force on university collections" for the discussion of common problems and possible solutions.

title: Subversive Philology? : Prosopography as a Relational and Corpus-Based Approach to Early Islamic History

Subjects: subject: Early Islamic history
subject: Islamic historiography

subject: Prosopographical methodology
subject: 290

description: This contribution suggests prosopographic engagement with the formative period of Islam as a systematic and corpus-based approach that enables the 'falsifiable' development of interpretative frameworks on a relational basis. This systematization of engagement with early Islamic history is crucial to overcome the influence of substantializing and frequently colonialist and (self-)orientalizing paradigms in academic research. At the same time, the importance of early Islamic history as the communal memory and 'resonating body' grounding the negotiation of Islamic normativities and public perceptions of Islam until today imbues this field of Islamic history with additional importance. This contribution sets out with an introduction to early Islamic history as a contested cultural memory and a review of prosopographical engagements with this period, suggesting prosopography or 'the study of an internally linked group of individuals' as an emic epistemological category in Arabic-Islamic scholarly traditions. I then suggest some pragmatic 'lessons learned' while engaging in a prosopographic case-study centered on individuals and groups affiliated to the Arab 'tribe' (qabīla) of Kinda. Subsequently, I present two examples of how the systematized engagement with early Islamic history through the prosopographical database of Kinda suggests innovative interpretations of the 'factual' history of events, as well as of the narrative dynamics that shaped the extant reports during the process of transmission.

description: The scaling of photoproduction $γp\toπ^0 p$ is investigated in the Reggeized model with $N^*$ and $Δ$ resonances included to describe resonance peaks up to photon energy $E_γ$= 3 GeV. Given the $t$-channel exchanges $ρ(770)+ω(780)+b_1(1235)+h_1(1170)$ Reggeized for the background contribution, the resonances of the Breit-Wigner form are introduced to agree with cross sections for total, differential and beam asymmetry in the low energy region. The scaled differential-cross sections $s^7{dσ/ dt}$ are reproduced to agree with the recent JLab data, revealing the production mechanism of the big bump structure around $W\approx 2.2$ GeV by the deep-dip pattern of the $ω$ exchange that originates from the zeros of the trajectory $α_ω(t)=0$ in the canonical phase, ${1\over2}(-1+e^{-iπα_ω(t)})$.

description: The electronic structures and topological properties of transition metal dipnictides $XPn_2$ ($X$=Ta, Nb; $Pn$=P, As, Sb) have been systematically studied using first-principles calculations. In addition to small bulk Fermi surfaces, the band anticrossing features near the Fermi level can be identified from band structures without spin-orbit coupling, leading to nodal lines in all these compounds. Inclusion of spin-orbit coupling gaps out these nodal lines leaving only a pair of disentangled electron/hole bands crossing the Fermi level. Therefore, the low energy physics can be in general captured by the corresponding two band model with several isolated small Fermi pockets. Detailed analysis of the Fermi surfaces suggests that the arsenides and NbSb$_2$ are nearly compensated semimetals while the phosphorides and TaSb$_2$ are not. Based on the calculated band parities, the electron and hole bands are found to be weakly topological non-trivial giving rise to surface states. As an example, we presented the surface-direction-dependent band structure of the surfaces states in TaSb$_2$.

description: The Food and Drug Administration (FDA)’s Adverse Event Reporting System (FAERS) is a post-marketing surveillance system which relies on spontaneous reports of adverse drug reactions (ADRs). Our objective was to evaluate how black box warning (BBW) updates impact ADR reporting rates. We searched MEDWATCH for all BBW updates issued between January 2014 and December 2016 and categorized them as new, major, and minor. Rates of relevant ADR reports from the FAERS database in the 4 years preceding and following a BBW update were assessed among the different BBW categories. Forty BBW updates were included (16 major, 3 new, and 21 minor). A meaningful increase in the proportion of relevant ADRs of all ADRs reported following BBW updates was documented for 53% of new or major updates and 24% of minor updates (p = 0.06). The median percentage of reported relevant ADRs increased by 5% following new and major BBW updates and decreased by 30% following minor BBW updates (p = 0.3). Reporting of adverse events to the FAERS database is affected by the severity and timing of related BBW updates, highlighting the drawbacks of spontaneous reporting systems. Regulators should promote proactive pharmacovigilance strategies to cope with these limitations.

description: A comparative study on mesh-based and mesh-less Computational Fluid Dynamics (CFD) approaches coupled with the Discrete Element Method (DEM) is presented. As the mesh-based CFD approach a Finite Volume Method (FVM) is used. A Smoothed Particle Hydrodynamics (SPH) method represents mesh-less CFD. The unresolved fluid model is governed by the locally averaged Navier-Stokes equations. A newly developed model for applying boundary conditions in the SPH is described and validation tests are performed. With the help of the presented comparative tests, the similarities and differences of DEM-FVM and DEM-SPH methods are discussed. Three test cases, comprised of a single solid particle sedimentation test, flow through a porous block and sedimentation of a porous block, are performed using both methods. Drag forces acting on solid particles highly depend on local fluid fractions. For comparative reasons, the size of a cell in FVM is chosen such that fluid fractions match those computed in SPH. In general, DEM-FVM and DEM-SPH methods exhibit good agreement with analytic reference results. Differences between DEM-SPH and DEM-FVM approaches were found mostly due to differences in computed local fluid fractions.

description: In this paper, we construct thin-shell wormholes from regular Ayon-Beato and Garcia black hole by employing cut and paste formalism and examine their stability. We analyze attractive and repulsive characteristics of wormholes corresponding to outward and inward-directed acceleration components, respectively. A general equation of state is assumed as a linear perturbation to explore stability of these constructed wormholes with and without cosmological constant. We consider linear, logarithmic and Chaplygin gas models for exotic matter and evaluate stability regions for different values of charge. For horizon-free case, it is found that the generalized Chaplygin gas model provides maximum stable regions in de Sitter background while the modified generalized Chaplygin gas and logarithmic gas yield maximum stable regions in anti-de Sitter spacetime.

description: This study aims to compare nature and frequency of adverse drug reactions (ADRs), time to first ADR, drug survival, and the share of ADRs in treatment discontinuation of first-time treatment with adalimumab (ADA) and etanercept (ETN) in real-world RA patients. Retrospective, single-center cohort study including naïve patients treated between January 2003-April 2020. Time to first ADR and drug survival of first-time treatment were studied using Kaplan–Meier and Cox-regression models up to 10 years, with 2- and 5-year post-hoc sensitivity analysis. Nature and frequencies of first-time ADRs and causes of treatment discontinuation were assessed. In total, 416 patients (ADA: 255, ETN: 161, 4865 patient years) were included, of which 92 (22.1%) experienced ADR(s) (ADA: 59, 23.1%; ETN: 33, 20.4%). Adjusted for age, gender and concomitant conventional DMARD use, ADA was more likely to be discontinued than ETN up to 2-, 5- and 10-year follow-up (adjusted HRs 1.63; 1.62; 1.59 (all p<0.001)). ADRs were the second reason of treatment discontinuation (ADA 20.7%, ETN 21.4%). Despite seemingly different nature and frequencies, ADRs are the second reason of treatment discontinuation for both bDMARDs. Furthermore, 2-, 5-, and 10-year drug survival is longer for ETN compared to ADA.

description: The safety and effectiveness of rivaroxaban versus vitamin K antagonists (standard of care [SOC]) for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF) was evaluated in Europe. Observational studies were conducted in the UK, the Netherlands, Germany, and Sweden. Primary safety outcomes were hospitalization for intracranial hemorrhage, gastrointestinal bleeding, or urogenital bleeding among new users of rivaroxaban and SOC with NVAF; outcomes were analyzed using cohort (rivaroxaban or SOC use) and nested case–control designs (current vs nonuse). Statistical analyses comparing rivaroxaban and SOC cohorts were not performed. Overall, 162,919 rivaroxaban users and 177,758 SOC users were identified. In the cohort analysis, incidence ranges for rivaroxaban users were 0.25–0.63 events per 100 person-years for intracranial bleeding, 0.49–1.72 for gastrointestinal bleeding, and 0.27–0.54 for urogenital bleeding. Corresponding ranges for SOC users were 0.30–0.80, 0.30–1.42, and 0.24–0.42, respectively. In the nested case–control analysis, current SOC use generally presented a greater risk of bleeding outcomes than nonuse. Rivaroxaban use (vs nonuse) was associated with a higher risk of gastrointestinal bleeding, but a similar risk of intracranial or urogenital bleeding, in most countries. Ischemic stroke incidence ranged from 0.31 to 1.52 events per 100 person-years for rivaroxaban users. Incidences of intracranial bleeding were generally lower with rivaroxaban than with SOC, whereas incidences of gastrointestinal and urogenital bleeding were generally higher. The safety profile of rivaroxaban for NVAF in routine practice is consistent with findings from randomized controlled trials and other studies.

description: During recent years, worries about fake news have been a salient aspect of mediated debates. However, the ubiquitous and fuzzy usage of the term in news reporting has led more and more scholars and other public actors to call for its abandonment in public discourse altogether. Given this status as a controversial but arguably effective buzzword in news coverage, we know surprisingly little about exactly how journalists use the term in their reporting. By means of a quantitative content analysis, this study offers empirical evidence on this question. Using the case of Austria, where discussions around fake news have been ubiquitous during recent years, we analyzed all news articles mentioning the term “fake news” in major daily newspapers between 2015 and 2018 (N = 2,967). We find that journalistic reporting on fake news shifts over time from mainly describing the threat of disinformation online, to a more normalized and broad usage of the term in relation to attacks on legacy news media. Furthermore, news reports increasingly use the term in contexts completely unrelated to disinformation or media attacks. In using the term this way, journalists arguably contribute not only to term salience but also to a questionable normalization process.

description: Terrorism, poverty, cancer: Citizens fear many things. Some of these fears are fueled by fear-related news as a form of sensational media coverage. As research on the variety of fears depicted in the news is scarce, this study analyzes the construction of fear-related news in the US and the UK from 1990 to 2017. By combining unsupervised machine learning in the form of topic modeling (N = 15,487) and manual content analysis (N = 1013), it explores the prevalence of themes and topics. It also analyzes the fear-inducing presentation of news through the use of fear appeals, specifically which (severe) threats are emphasized by the media. Results indicate that the media do not only concentrate on fears of violence and crime, but also on fears of economic downturn, political unrest, or social fears concerning unemployment. The most prominent threat emphasized across topics is death, followed by political and economic threats. Topic prevalence is highly volatile and coverage has not become more fear-inducing over time. Overall, this study contributes to a better understanding of how news media may foster fear: through mirroring a variety of economic, political and social fears and emphasizing specific threats across them.
Lepton flavour violating decays of $μ$ and $τ$ lepton in a gauge group $SU_L(2)\times SU_R(2)\times SU_l(2)$

description: The electroweak unification group $ SU(2)_L\times SU(2)_R\times SU(2)_Y $ is proposed for the charged lepton flavor violating decays of the muon ($μ$) and tau ($τ$) leptons. The group $SU(2)_Y$ is in the lepton space. The left-handed leptons and anti-leptons are assigned to the fundamental representation $(2,2,\bar{2})$ of the semi-simple group. The gauge group $SU(2)_Y$ is spontaneously broken to $U(1)_{Y_1}$, where $Y_1=-L=\pm1$ is the hypercharge, by introducing a scalar multiplet $Σ$ which belongs to the triplet representation 3 of the $SU(2)_Y$ and is singlet under $SU(2)_L\times SU(2)_R$. At this stage charged vector bosons $Y^\pm$ of $SU(2)_Y$ which mediate the lepton flavor violating decays acquire masses and are decoupled with one Higgs scalar $H_Σ^0$. The residual group $SU(2)_L\times SU(2)_R\times U(1)_{Y_1}$ has all the features of the left-right electroweak unification group extensively studied in the literature. The probability for lepton flavor violating decays is $\left(\frac{\sin^2θ_W}{1-2\sin^2θ_W}\right)^2\left(\frac{m_{W_L}}{m_Y}\right)^4$.

description: In this Rapid Communication, we investigate the universal properties of a spin-polarized two-component Fermi gas in one dimension (1D) using Bethe ansatz. We discuss the quantum phases and phase transitions by obtaining exact results for the equation of state, the contact, the magnetic susceptibility and the contact susceptibility, giving a precise understanding of the 1D analogue of the Bose-Einstein condensation and Bardeen-Cooper-Schrieffer crossover in three dimension (3D) and the associated universal magnetic properties. In particular, we obtain the exact form of the magnetic susceptibility $χ\sim {1}/{\sqrt{T}}\exp(-Δ/T)$ at low temperatures, where $Δ$ is the energy gap and $T$ is the temperature. Moreover, we establish exact upper and lower bounds for the relation between polarization $P$ and the contact $C$ for both repulsive and attractive Fermi gases. Our findings emphasize the role of the pair fluctuations in strongly interacting 1D fermion systems that can shed light on higher dimensions.

description: The research institutions, especially the public universities in Latin America, have the challenge to demonstrate the relevance of their management and results linked to the socio-productive and interest sectors, but in the middle of international rankings or traditional evaluation systems with partial indicator and less linked to the reality and resources of their organizations. As a result, many contributions and transformative actions are not visible. This raises the use of strategies that allow to measure the own management for the objectives of the real interested parties and with the available resources. With the idea that evaluation is not a process of discrediting, but a process of empowerment, a tool and a commitment that helps to improve the transparency and accountability of processes. Research evaluation systems can be strengthened by institutional open repositories, and in the same way repositories can be strengthened. The strategy of the Universidad de Costa Rica has been to adopt a process approach, based on its own resources or those available in the institutions, but framed in the possible improvement and promotion of good practices. This has made it possible to integrate the repository into many parts of processes and systems, conceived as spaces and tools to help document the results of a management process. For example, for teaching, research or social action, or linking, in many ways, not only with a scientific article, since it allows us a large amount of documentary typology, for example, a peer review, contribution to a conference, articles, patents, videos, maps, photographs. In addition, research units can promote this space to help control or monitor the management of your collaboration. For transparency and monitoring of the research management cycle, it is possible to link the repositories to project systems and associate them with a researcher, a research area or a unit, in addition to using them for reports requested by different entities, important for data presentation externally or internally, and for contributing to the best strategies to promote areas or lines of research, including fundraising. All of this not dependent on the use of fixed evaluations, but rather promotes the use according to the needs of the process. However, it is also possible to set up an evaluation system for specific objectives, such as an academic career, which considers knowledge transfer criteria. The uses depend on the objectives of the institutions, but also on the strategies for promoting the repositories and the support of the authorities, which is a fundamental key to the actions.

description: Clustering is an underspecified task: there are no universal criteria for what makes a good clustering. This is especially true for relational data, where similarity can be based on the features of individuals, the relationships between them, or a mix of both. Existing methods for relational clustering have strong and often implicit biases in this respect. In this paper, we introduce a novel similarity measure for relational data. It is the first measure to incorporate a wide variety of types of similarity, including similarity of attributes, similarity of relational context, and proximity in a hypergraph. We experimentally evaluate how using this similarity affects the quality of clustering on very different types of datasets. The experiments demonstrate that (a) using this similarity in standard clustering methods consistently gives good results, whereas other measures work well only on datasets that match their bias; and (b) on most datasets, the novel similarity outperforms even the best among the existing ones.

description: We study propagation of waves and appearance of caustics in k-essence and galileon theories. First we show that previously known solutions for travelling waves in k-essence and galileon models correspond to very specific fine-tuned initial conditions. On the contrary, as we demonstrate by the method of characteristics, generic initial conditions leads to a wave in k-essence which ends up with formation of caustics. Finally, we find that any wave solution in pure k-essence is also a solution for a galileon theory with the same k-essence term. Thus in the Horndeski theory with a k-essence term formation of caustics is generic. We discuss physical consequences of the caustics formation and possible ways to cure the problem.

description: Trials evaluating the efficacy of IVF and various treatment options often focus on upstream outcome measures, improvements which may not translate into clinical outcome improvements. A cross-sectional online survey was distributed globally among IVF patients. Respondents were randomised to view one of 16 statements about a hypothetical IVF treatment option called ‘FertiSure’, stated to improve one of four upstream outcomes. Statements varied in whether they contained information stating that FertiSure was not proven to improve live-birth rates and about potential risks. Many patients inferred that improvements in upstream outcomes would result in improvements in the probability of live-birth. Nearly 80% of respondents were willing to use FertiSure. Respondents told that FertiSure was not proven to improve live-birth rates and were less willing to use FertiSure. More respondents agreed that FertiSure may pose a risk to patients when they were told this was the case. However, this did not affect their willingness to use FertiSure. Interestingly, 34% of respondents believed FertiSure would not improve the probability of live-birth but were still willing to use it. These results have implications for IVF clinic websites and information about treatment options which may not routinely contain statements about the limited evidence-base and possible risks.

description: This study aimed to assess the knowledge regarding female fertility, infertility treatments and the attitudes regarding parenthood of medical students in Pakistan. Delayed childbirth among medical trainees due to extended years of medical education and training puts this population at a higher risk for involuntary childlessness later in life due to age-related decline in female fertility. A knowledge, attitude and practice study was carried out among medical students in Karachi in July 2021 using the English version of the Swedish Fertility Awareness questionnaire, which has been used in similar studies. Most participants wished to have children at some point in the future. However, a majority of students did not have sufficient knowledge regarding age-related decline in female fertility and overestimated the efficacy of infertility treatments. The results of this study indicate that despite planning to have children and placing great importance on parenthood, medical students severely overestimate female fertility and plan to start having children at an age at which female fecundity has begun to decline. These findings highlight a need for better provisions regarding fertility knowledge in the curriculum for medical students, as they are an at-risk group for involuntary childlessness due to age-related fertility decline.

description: The axion monodromy model involves a canonical scalar field that is governed by a linear potential with superimposed modulations. The modulations in the potential are responsible for a resonant behavior which gives rise to persisting oscillations in the scalar and, to a smaller extent, in the tensor power spectra. Interestingly, such spectra have been shown to lead to an improved fit to the cosmological data than the more conventional, nearly scale invariant, primordial power spectra. The scalar bi-spectrum in the model too exhibits continued modulations and the resonance is known to boost the amplitude of the scalar non-Gaussianity parameter to rather large values. An analytical expression for the scalar bi-spectrum had been arrived at earlier which, in fact, has been used to compare the model with the cosmic microwave background anisotropies at the level of three-point functions involving scalars. In this work, with future applications in mind, we arrive at a similar analytical template for the scalar-scalar-tensor cross-correlation. We also analytically establish the consistency relation (in the squeezed limit) for this three-point function. We conclude with a summary of the main results obtained.

Competition between Kondo effect and RKKY physics in graphene magnetism

description: The cooperative behavior of quantum impurities on 2D materials, such as graphene and bilayer graphene, is characterized by a non-trivial competition between screening (Kondo effect), and Ruderman-Kittel-Kasuya-Yosida (RKKY) magnetism. In addition, due to the small density of states at the Fermi level, impurities may not couple to the conduction electrons at all, behaving as free moments. Employing a recently developed {\em{exact}} numerical method to study multi-impurity lattice systems, we obtain non-perturbative results that dramatically depart from expectations based on the conventional RKKY theory. At half-filling and for weak coupling, impurities remain in the local moment regime when they are on opposite sublattices, up to a critical value of the interactions when they start coupling anti-ferromagnetically with correlations that decay very slowly with inter-impurity distance. At finite doping, away from half-filling, ferromagnetism is completely absent and the physics is dominated by a competition between anti-ferromagnetism and Kondo effect. In bilayer graphene, impurities on opposite layers behave as free moments, unless the interaction is of the order of the hopping or larger.

description: This study investigates 1) teachers’ motivation to attend the training of Genre-based English Teaching, and 2) teachers’ intention to implement the newly introduced teaching approach. Teachers’ motivation was explained using self-determination theory, while intention was predicted using seven predictors from both the theory of planned behaviour, and the context of the study.
 Data were collected from 210 school English teachers in Yogyakarta province of Indonesia, using a questionnaire consisting of eight subscales. The first four subscales were developed following the guidance for questionnaire development to measure teachers’ intention and its three predictors, while the other four subscales of teacher motivation to attend a training program, engagement in the program, self-efficacy to implement the result of the program, and perceived school climate were either adopted or adapted from published questionnaires. Data concerning motivations were analysed using descriptive statistics and MANOVA, while data about intention were analysed using Structural Equation Modelling.
 Findings suggest that teacher motivation changed in both dimensions of quantity and quality. Initial controlled types of motivation became more autonomous when participants experienced internalisation. Participants reported different types of motivation that indicated motivational overlaps, by reporting both high intrinsic motivation and identified regulation, on one hand, and high external regulation on the other hand. Findings also suggested that only teaching experiences contributed significantly to differences in teachers’ motivation. Although the theory of planned behaviour proposes three predictors of intention (attitudes, subjective norms, perceived behavioural control), this study revealed that subjective norms and perceived behaviour control predicted teachers’ intention but teachers’ attitudes did not. Teachers’ emotional engagement in the training of Genre-based English Teaching proved to be a significant predictor of teacher intention. These findings are interpreted and implications discussed in relation to teachers and the teaching profession in the Indonesian context, and particularly in the area of teacher professional development

description: If Dark Matter is made of Weakly Interacting Massive Particles (WIMPs) with masses below $\sim$20 GeV, the corresponding nuclear recoils in mainstream WIMP experiments are of energies too close, or below, the experimental threshold. Gas Time Projection Chambers (TPCs) can be operated with a variety of target elements, offer good tracking capabilities and, on account of the amplification in gas, very low thresholds are achievable. Recent advances in electronics and in novel radiopure TPC readouts, especially micro-mesh gas structure (Micromegas), are improving the scalability and low-background prospects of gaseous TPCs. Here we present TREX-DM, a prototype to test the concept of a Micromegas-based TPC to search for low-mass WIMPs. The detector is designed to host an active mass of $\sim$0.300 kg of Ar at 10 bar, or alternatively $\sim$0.160 kg of Ne at 10 bar, with an energy threshold below 0.4 keVee, and is fully built with radiopure materials. We will describe the detector in detail, the results from the commissioning phase on surface, as well as a preliminary background model. The anticipated sensitivity of this technique may go beyond current experimental limits for WIMPs of masses of 2-8 GeV.
