description: NGC 4473 is a so--called double sigma (2$σ$) galaxy, i.e. a galaxy with rare, double peaks in its 2D stellar velocity dispersion. Here, we present the globular cluster (GC) kinematics in NGC 4473 out to $\sim10\,R_e$ (effective radii) using data from combined HST/ACS and Subaru/Suprime--Cam imaging and Keck/DEIMOS spectroscopy. We find that the 2$σ$ nature of NGC 4473 persists up to 3 $R_e$, though it becomes misaligned to the photometric major axis. We also observe a significant offset between the stellar and GC rotation amplitudes. This offset can be understood as a co--addition of counter--rotating stars producing little net stellar rotation. We identify a sharp radial transition in the GC kinematics at $\sim4\,R_e$ suggesting a well defined kinematically distinct halo. In the inner region ($<4\,R_e$), the blue GCs rotate along the photometric major axis, but in an opposite direction to the galaxy stars and red GCs. In the outer region ($>4\,R_e$), the red GCs rotate in an opposite direction compared to the inner region red GCs, along the photometric major axis, while the blue GCs rotate along an axis intermediate between the major and minor photometric axes. We also find a kinematically distinct population of very red GCs in the inner region with elevated rotation amplitude and velocity dispersion. The multiple kinematic components in NGC 4473 highlight the complex formation and evolutionary history of this 2$σ$ galaxy, as well as a distinct transition between the inner and outer components.

description: The question of how people’s preferences are shaped by their choices has generated decades of research. In a classic example, work on cognitive dissonance has found that observers who must choose between two equally attractive options subsequently avoid the unchosen option, suggesting that not choosing the item led them to like it less. However, almost all of the research on such choice-induced preference focuses on adults, leaving open the question of how much experience is necessary for its emergence. Here, we examined the developmental roots of this phenomenon in preverbal infants (N = 189). In a series of seven experiments using a free-choice paradigm, we found that infants experienced choice-induced preference change similar to adults’. Infants’ choice patterns reflected genuine preference change and not attraction to novelty or inherent attitudes toward the options. Hence, choice shapes preferences—even without extensive experience making decisions and without a well-developed self-concept.

description: We examine the daily sleep of leaders as an antecedent to daily abusive supervisory behavior and work unit engagement. Drawing from ego depletion theory, our theoretical extension includes a serial mediation model of nightly sleep quantity and quality as predictors of abusive supervision. We argue that poor nightly sleep influences leaders to enact daily abusive behaviors via ego depletion, and these abusive behaviors ultimately result in decreased daily subordinate unit work engagement. We test this model through an experience sampling study spread over 10 workdays with data from both supervisors and their subordinates. Our study supports the role of the indirect effects of sleep quality (but not of sleep quantity) via leader ego depletion and daily abusive supervisor behavior on daily subordinate unit work engagement.

description: 2015年以来涌入欧洲的难民人数大幅增加，不仅影响到欧洲社会秩序的稳定与团结，更对欧洲经济社会的发展造成一定压力。面对不断上升的难民危机，是拒绝还是接纳，欧洲面临人道主义和国家利益的两难选择。本文从国际移民的跨国流动对国家边界内的治理能力所带来的冲击和挑战切入，结合国际移民政策理论分析了国家的三类基本选择，并进一步从国际移民治理机制公共产品的角度为欧洲难民危机的解决提供全新的思考路径。当然，中国也应抓住机会成为国际移民治理机制的倡导者，参与到全球治理的规则制定之中。 The influx of refugees in Europe in 2015 has greatly increased, which not only affects the stability and unity of European society, but also exerts certain pressure on its economic development. In the face of the refugee crisis, it is a dilemma for the European countries to choose either humanitarian or national interests. Starting from the impact and challenge that international migration has had on effective governance within national boundaries, this paper uses the theories of international migration to analyze the three basic choices. Further, the authors provide a new way of thinking about the European refugee crisis from the perspective of international migration governance mechanisms. Of course, China should seize the opportunity to become an advocate of the international migration governance mechanism and rule maker of the global governance.

description: Searches for supersymmetric top quarks at the LHC have been making great progress in pushing sensitivity out to higher mass, but are famously plagued by gaps in coverage around lower-mass regions where the decay phase space is closing off. Within the common stop-NLSP / neutralino-LSP simplified model, the line in the mass plane where there is just enough phase space to produce an on-shell top quark remains almost completely unconstrained. Here, we show that is possible to define searches capable of probing a large patch of this difficult region, with S/B ~ 1 and significances often well beyond 5 sigma. The basic strategy is to leverage the large energy gain of LHC Run 2, leading to a sizable population of stop pair events recoiling against a hard jet. The recoil not only re-establishes a MET signature, but also leads to a distinctive anti-correlation between the MET and the recoil jet transverse vectors when the stops decay all-hadronically. Accounting for jet combinatorics, backgrounds, and imperfections in MET measurements, we estimate that Run 2 will already start to close the gap in exclusion sensitivity with the first few 10s of inverse-fb. By 300/fb, exclusion sensitivity may extend from stop masses of 550 GeV on the high side down to below 200 GeV on the low side, approaching the "stealth" point at m(stop) = m(top) and potentially overlapping with limits from top pair cross section and spin correlation measurements.

description: The causes of workplace deviance are of increasing interest to organizations. We integrate psychological and neurocognitive perspectives to examine the effects of sleep deprivation on workplace deviance. Utilizing self-regulatory resource theories, we argue that sleep deprivation decreases individuals’ self-control while increasing hostility, resulting in increased workplace deviance. We test our hypotheses using two samples: one comprised of nurses from a large medical center and another comprised of undergraduate students participating in a lab study. Results from both samples largely converge in supporting our hypotheses.

description: 本文以2011年美国曼哈顿广场上的中国国家形象宣传片为对象，对其效果进行了实证性评估。为此，笔者给出了衡量国家形象宣传片效果的一般性标准和指标。其中，衡量标准是看其在投放后是否改善了美国民众对中国的形象认知；量化指标分别是：目标国媒体报道的数量与报道的倾向性、目标国民众的参与度与民众的态度倾向和目标国民众的行为。通过分析发现，2011年中国国家形象宣传片并没有达到预期的乐观效果。美国主流媒体报道偏少、报道颇为负面；美国民众参与度低，对国家形象宣传片和中国的好感度不高；宣传片的播放也未引发更高的来华旅游热。本文认为，今后国家形象宣传片的建设应关注两个方面：一是注重文化差异，增强话语的可读性；二是言行一致，增强话语的可信性。 This article empirically assessed the effect of China’s national publicity film launched in Times Square in Manhattan, New York. To this end, the author gave a set of general criteria and indicators to measure the effect of national publicity films. Whether the publicity film was effective depends on whether American people’s image perceptions of China were improved after it was launched. Quantitative indicators are: the number of reports in the target country and the predispositions of the reports; the target country people’s participation and their predispositions; and the real behavior of the target country people. The analysis revealed that the 2011 national publicity film did not achieve the anticipated effect. The number of U.S. mainstream media reports was less than expected and their evaluations were quite negative; the participation of American people was low and the extent of the favorability both of the publicity film and China was not high; and the launch of the publicity film did not trigger a travel boom to China. Accordingly, this article suggested that the future implementation of China’s national publicity films focuses on two aspects: first, pay attention to cultural differences and enhance the comprehensibility of the discourse; second, practice what it preaches and strengthen the credibility of the discourse.

Leadership

description: Workplace humor is ubiquitous, yet scholars know little about how it affects employees’ behaviors in organizations. We draw on an emerging psychological theory of humor—benign violation theory—to suggest that a leader’s sense of humor often conveys counter-normative social information in organizations. We integrate this theory with social information processing theory to develop hypotheses about the effects of a leader’s sense of humor on follower behavior. We suggest that although a leader’s sense of humor is positively associated with leader−member exchange and ultimately work engagement, it can also signal to followers the acceptability of norm violation at work. These perceptions in turn are positively associated with followers’ deviance. Furthermore, we propose that these indirect effects are moderated by leader aggressive humor. Data from two three-wave field studies in China and the United States provide support for our hypotheses. Taken together, our results suggest that a leader’s sense of humor can be a mixed blessing and elicit unforeseen negative behaviors from their followers.

description: Considerable recent attention has been given to the study of shape formation using modern responsive materials that can be preprogrammed to undergo spatially inhomogeneous local deformations. In particular, nematic liquid crystal polymer networks offer exciting possibilities in this context. In this paper, we discuss the generation of Gaussian curvature in thin nematic sheets using smooth in-plane director fields patterned across the surface. We highlight specific patterns which encode constant Gaussian curvature of prescribed sign and magnitude and present experimental results which appear to support the theoretical predictions. Specifically, we provide experimental evidence for the realization of positive and negative Gaussian curvature in glassy and elastomeric liquid crystal polymer networks through the stimulation of smoothly varying in-plane director fields.

The US considered the TPP as a new effective tool to contain the influence of China in Asia-Pacific areas. Similarly China deems it an obstacle set by the US to block its emergence. TPP may cause mutual misjudgment and confrontation and conflict between the US and China in the future.

description: We investigate the role of mindfulness as a regulatory factor by examining whether it mitigates the relationship between justice and retaliation. Drawing on theories of self-regulation, we integrate work on justice with emerging frameworks that identify mindfulness as an important work-related regulatory variable (Glomb, Duffy, Bono, & Yang, 2011). Specifically, we identify the role of mindfulness as a buffer of the ruminative thoughts and negative emotions that link injustice to retaliation. We test mediated moderation hypotheses in 2 samples. In Sample 1, two behavioral measures of retaliation are assessed in an experiment that manipulated both injustice and mindfulness. In Sample 2, we generalize our model to the field, examining employee responses regarding experiences with workplace injustice and retaliation. Results of both studies converge to support the proposed mediated moderation model that mindfulness buffers the effect of injustice on rumination and negative emotions, thus reducing retaliation. Our findings contribute to the broader literatures on self-regulation, organizational justice, and retaliation.

description: We discuss what kinds of combinations of Yukawa interactions can generate the Majorana neutrino mass matrix. We concentrate on the flavor structure of the neutrino mass matrix because it does not depend on details of the models except for Yukawa interactions while determination of the overall scale of the mass matrix requires to specify also the scalar potential and masses of new particles. Thus, models to generate Majorana neutrino mass matrix can be efficiently classified according to the combination of Yukawa interactions. We first investigate the case where Yukawa interactions with only leptons are utilized. Next, we consider the case with Yukawa interactions between leptons and gauge singlet fermions, which have the odd parity under the unbroken Z_2 symmetry. We show that combinations of Yukawa interactions for these cases can be classified into only three groups. Our classification would be useful for the efficient discrimination of models via experimental tests for not each model but just three groups of models.

description: Products predominantly associated with utilitarian attitudes at the category level support less utilitarian and more symbolic attitudes at the brand level. Products predominantly associated with symbolic attitudes at the category level support less symbolic and more utilitarian attitudes at the brand level (H1). This reflects the following statement from the paper's abstract: “Specifically, product categories that are generally associated with utilitarian attitudes are associated with less utilitarian, more symbolic attitudes when branded, whereas product categories that are generally associated with symbolic attitudes are associated with more utilitarian, less symbolic attitudes when branded.” To test the claim, participants evaluated eight products (four utilitarian products and four symbolic products), with product order counterbalanced and symbolic and utilitarian products intermixed. The authors randomly assigned participants to evaluate branded or unbranded products, and they further randomly assigned those evaluating branded products to one of two sets of brand names. Participants rated each product’s associations with symbols and benefits, and the authors obtain difference scores by subtracting each product’s symbolism rating from its benefits rating, revealing the degree to which each product supports, on balance, more utilitarian (higher numbers) or more symbolic (lower numbers) attitudes. The authors perform a 2 (level: category or brand) × 2 (unbranded product type: utilitarian or symbolic) mixed ANOVA on the difference scores (averaged for each product type). A 2 (level: category or brand) × 2 (unbranded product type: utilitarian or symbolic) mixed ANOVA on the difference scores (averaged for each product type) revealed the predicted level × product type interaction (F(1, 204) = 7.70, p = .006).

description: Over the past decades hollow-cathode lamps have been calibration standards for spectroscopic measurements. Advancing to cm/s radial velocity precisions with the next generation of instruments requires more suitable calibration sources with more lines and less dynamic range problems. Fabry-Perot interferometers provide a regular and dense grid of lines and homogeneous amplitudes making them good candidates for next generation calibrators. We investigate the usefulness of Fabry-Perot etalons in wavelength calibration, present an algorithm to incorporate the etalon spectrum in the wavelength solution and examine potential problems. The quasi periodic pattern of Fabry-Perot lines is used along with a hollow-cathode lamp to anchor the numerous spectral features on an absolute scale. We test our method with the HARPS spectrograph and compare our wavelength solution to the one derived from a laser frequency comb. The combined hollow-cathode lamp/etalon calibration overcomes large distortion (50 m/s) in the wavelength solution of the HARPS data reduction software. Direct comparison to the laser frequency comb bears differences of only maximum 10 m/s. Combining hollow-cathode lamps with Fabry-Perot Interferometers can lead to substantial improvements in the wavelength calibration of echelle spectrographs. Etalons can provide economical alternatives to the laser frequency comb, especially for smaller projects.
Students’ attitudes towards group based project exams in two engineering programmes

description: At Aalborg University, engineering students work in groups on PBL projects. The assessment of these projects is through group exams except between 2007 and 2013 when the law forbade group exams. Prior to 2007, research showed that students preferred the group exams and a new study was made after the 2013 reintroduction of group exams. Again the result is that students prefer the group exam, but there are significant differences between students from various engineering programmes. We compare the programmes Architecture and Design with Software engineering, the latter being the most positive towards the group exam. A further result is that one third of the students testified that facing a new type of exam than previous did not affect their behaviour at all. This might suggest that the “backwash” effect of exam on student behaviour is not as present in these students as often expected and argued in education research.

description: This study examines internal and external factors affecting insurance companies’ profitability in Ethiopia. Profitability is proxied by ROA, which is a key indicator of insurance companies’ profitability. As internal explanatory variables company size, leverage, liquidity, firm growth, age, volume of capital and tangibility are used, moreover, as external explanatory variables inflation and GDP are also used to examine the most determinants of profitability of insurance companies. Panel data covering the period of 2005 to 2014 are analyzed for nine insurance companies. The study uses multiple linear regression models, and fixed effect technique has been applied to find out the most significant variables which affect the insurance companies’ profitability. As a result, the result shows that from internal factors leverage, firm growth and tangibility of assets are the most significant determinants of profitability of insurance companies in Ethiopia, of which, firm growth has positive impact, on the other hand leverage and tangibility of assets have negative impact on profitability of insurers. From macroeconomic factors, inflation has a negative and significant impact on insurers’ profitability The result also reveals th

description: Employees are getting less sleep, which has been shown to deplete self-regulatory resources and increase unethical behavior (Barnes, Schaubroeck, Huth, & Ghumman, 2011; Christian & Ellis, 2011). In this study, we extend the original mediated model by examining the role of 2 moderators in the relationship between sleep deprivation, depletion, and deceptive behavior. First, we derive psychological arguments from the psychopharmacology literature to hypothesize that caffeine moderates the relationship between sleep deprivation and depletion by replenishing self-regulatory resources. Second, we draw from recent research in social psychology to hypothesize that social influence moderates the relationship between depletion and deceptive behavior, such that depleted individuals are less able to resist the negative influence of others. Results of a laboratory study provide support for our expanded model combining mediation and moderation, adding to our understanding of the role of sleep deprivation in the incidence of workplace deception.

description: Based on the assumption that wellbeing influences learning, the aim of this paper is to provide insight into students’ emotional responses to different learning designs. By comparing three different learning designs their respective influence on students’ feelings about and motivation for learning is discussed. This experimental, controlled comparison study was conducted in an introductory computer programming course. The three learning designs were: 1. A classical teacher-lead course; 2. A problem based learning (PBL) course; and 3. A PBL course combined with the use of LEGO Mindstorms Robots. Three different studies were used for data collection: 1. A questionnaire survey with 229 students from groups exposed to the three different learning designs; 2. Six qualitative walk-alongs collecting data from these groups by informal interviews and observations; 3. Class room observations. Findings from the three studies were discussed in three focus group interviews with 10 students from each learning design. The research was conducted among first year students in Computer Science at the Informatics School, Universidad Nacional de Costa Rica.

description: Stimulated emission depletion (STED) microscopy has become a powerful imaging and localized excitation method beating the diffraction barrier for improved lateral spatial resolution in cellular imaging, lithography, etc. Due to specimen-induced aberrations and scattering distortion, it has been a great challenge for STED to maintain consistent lateral resolution deeply inside the specimens. Here we report on a deep imaging STED microscopy by using Gaussian beam for excitation and hollow Bessel beam for depletion (GB-STED). The proposed scheme shows the improved imaging depth up to ~155μm in solid agarose sample, ~115μm in PDMS and ~100μm in phantom of gray matter in brain tissue with consistent super resolution, while the standard STED microscopy shown a significantly reduced lateral resolution at the same imaging depth. The results indicate the excellent imaging penetration capability of GB-STED, making it a promising tool for deep 3D imaging optical nanoscopy and laser fabrication.

description: Many researchers have concerns about work engagement's distinction from other constructs and its theoretical merit. The goals of this study were to identify an agreed‐upon definition of engagement, to investigate its uniqueness, and to clarify its nomological network of constructs. Using a conceptual framework based on Macey and Schneider (2008; Industrial and Organizational Psychology, 1, 3–30), we found that engagement exhibits discriminant validity from, and criterion related validity over, job attitudes. We also found that engagement is related to several key antecedents and consequences. Finally, we used meta‐analytic path modeling to test the role of engagement as a mediator of the relation between distal antecedents and job performance, finding support for our conceptual framework. In sum, our results suggest that work engagement is a useful construct that deserves further attention.

description: Recently there has been interest in extending ghost-free massive gravity, bi-gravity, and multi-gravity by including non-standard kinetic terms and matter couplings. We first review recent proposals for this class of extensions, emphasizing how modifications of the kinetic and potential structure of the graviton and modifications of the coupling to matter are related. We then generalize existing no-go arguments in the metric language to the vielbein language in second-order form. We give an ADM argument to show that the most promising extensions to the kinetic term and matter coupling contain a Boulware-Deser ghost. However, as recently emphasized, we may still be able to view these extensions as effective field theories below some cutoff scale. To address this possibility, we show that there is a decoupling limit where a ghost appears for a wide class of matter couplings and kinetic terms. In particular, we show that there is a decoupling limit where the linear effective vielbein matter coupling contains a ghost. Using the insight we gain from this decoupling limit analysis, we place an upper bound on the cutoff for the linear effective vielbein coupling. This result can be generalized to new kinetic interactions in the vielbein language in second-order form. Combined with recent results, this provides a strong uniqueness argument on the form of ghost-free massive gravity, bi-gravity, and multi-gravity.

description: In this paper we describe a “Train the Tutor” programme (TtT) for developing the metacognitive skills, facilitator skills, and tutor skills of students in a problem based learning (PBL) context. The purpose of the programme was to train 2nd and 3rd year undergraduate students in psychology to become effective PBL tutors for “freshmen” (1st year psychology students). Based on the 3C3R concept of Hung (2006), various instructional problems have been designed and used in a 6 steps training programme. The programme has been evaluated both in a formative and summative approach through a quasi-experimental control group design with pre- and post-measurements before and after the training programme. The study was conducted as part of a curriculum re-design for promoting problem based learning in psychology courses for undergraduate students in a university of applied science. The results indicate the importance of metacognitive skills of the tutor for effectively facilitating the learning process in a PBL context.

description: Since the 1970’s, Aalborg University has been developing a new pedagogical model in higher education: The Project Oriented – Problem Based Learning (PO-PBL). In particular, the Faculty of Engineering and Science has developed a pedagogical proposal that introduces students to a different type of learning. One of the theoretical frameworks underpinning the understanding of learning is the socio-cultural perspective. This paper aims at exploring and analyzing the PO-PBL model from this theoretical perspective. In addition, this reading may also open a new viewpoint in science teaching for other universities.

Chronotype Diversity in Teams: Toward a Theory of Team Energetic Asynchrony

description: We introduce the concept of chronotype diversity into the team diversity literature. We define chronotype diversity as the extent to which team members differ in their biological predispositions toward the optimal timing of daily periods of activity and rest. To explain the effects of chronotype diversity on team outcomes, we develop a theory of team energetic asynchrony. Team energetic asynchrony refers to temporal asymmetries among team members’ daily peaks and troughs in physical and psychological energy. In our theoretical model we delineate how chronotype diversity affects team performance by specifying three specific team processes (coordination, information processing, and backing up behavior) that convey unique team diversity effects of energetic asynchrony. In doing so we propose that chronotype diversity can have either positive or negative effects on team processes and outcomes, depending on whether teams recognize differences in members’ chronotypes and structure team work accordingly. We also discuss the potential effects of chronotype subgroup formation and the benefits and pitfalls of low chronotype diversity.
Reflections on remaining obstacles in a primary-care oriented pure PBL curriculum after twelve years of implementation

description: A pioneer primary-care oriented pure PBL curriculum, based on constructivism and adult learning theories combined with Morin’s complex thinking, was implemented in our medical school since 2002. Regardless of warnings opportunely made because the basic requirements for its successful implementation could not be fully fulfilled in practice, the experience was carried out and, while partially amended, still endures. This allows revealing several obstacles in many operational aspects, here recalled and/or characterized. Besides becoming helpful not only for counseling again to our own medical school about them but for warning and informing to those institutions with similar problems, the present analysis leads to a preventive final reflection: when designing and implementing a medical curriculum in general and particularly a pure PBL one, a thorough analysis of the contextual and operational factors, a flexible procedure and continuous objective evaluations for further adjustments become keystones for guaranteeing its fruitful implementation.

description: We introduce the exchangeable rewiring process for modeling time-varying networks. The process fulfills fundamental mathematical and statistical properties and can be easily constructed from the novel operation of random rewiring. We derive basic properties of the model, including consistency under subsampling, exchangeability, and the Feller property. A reversible sub-family related to the Erdős-Rényi model arises as a special case.

Facilitating facilitators to facilitate, in problem or enquiry based learning sessions
Creators: name: Coelho, Catherine

description: Problem based learning (PBL) has been used in dental education over the past 20 years and uses a patient case scenario to stimulate learning in a small group setting, where a trained facilitator does not teach but guides the group to bring about deep contextualized learning, to be empathetic to each other and to encourage fair and equitable contribution from individual learners. Learners are encouraged to appreciate that they individually perform better when they actively participate in the group and share resources, than when they learn in isolation (Bandura, 1977, Freire, 1972, Lave and Wenger, 1991, Kolb, 1984 and Vygotsky, 1978).

description: Gibbs sampling is a Markov Chain Monte Carlo (MCMC) method often used in Bayesian learning. MCMC methods can be difficult to deploy on parallel and distributed systems due to their inherently sequential nature. We study asynchronous Gibbs sampling, which achieves parallelism by simply ignoring sequential requirements. This method has been shown to produce good empirical results for some hierarchical models, and is popular in the topic modeling community, but was also shown to diverge for other targets. We introduce a theoretical framework for analyzing asynchronous Gibbs sampling and other extensions of MCMC that do not possess the Markov property. We prove that asynchronous Gibbs can be modified so that it converges under appropriate regularity conditions -- we call this the exact asynchronous Gibbs algorithm. We study asynchronous Gibbs on a set of examples by comparing the exact and approximate algorithms, including two where it works well, and one where it fails dramatically. We conclude with a set of heuristics to describe settings where the algorithm can be effectively used.

description: We analyse the environment of the supermassive black hole (SMBH) in the centre of a massive elliptical galaxy NGC 1275 in the Perseus cluster, hosting the radio source 3C 84. We focus on the young radio lobe observed inside the estimated Bondi accretion radius. We discuss the momentum balance between the jet associated with the lobe and the surrounding gas. The results are compared with the proper motion of the radio lobe obtained with the very long baseline interferometry. We find that under assumption of a high-density environment >~ 100 cm^-3), the jet power must be comparable to the Eddington luminosity --- this is clearly inconsistent with the current moderate activity of 3C 84, which indicates instead that the jet is expanding in a very low density region (

description: This study investigates how hospitality management students appreciate the role and application of the seven-step procedure in problem-based learning. A survey was developed containing sections about personal characteristics, recall of the seven steps, overall report marks, and 30 statements about the seven-step procedure. The survey was administered to a sample of 101 first-, second- and third-year hotel school students. Results show a low recall but positive opinion about the seven-step procedure. Particularly step 4 (conceptualizing), step 6 (self-study between tutorials) and step 7 (synthesizing new information) need attention. Some suggestions are put forward for strengthening the process of problem-based hospitality education.
