The Impact of Community Engagement in Teaching and Learning Repositories

HumBox is a community repository for humanities-focused resources. It was created using a co-design process that revealed that for the repository to successfully support a community its users needed to have an identity in the repository, control of their own resources and lightweight communication tools. Now that HumBox has been running for over two years it is possible to re ect on these ideals and the tools that support them, and in this paper we present a survey of HumBox users that has discovered that the community tools were used to re ne resources, encouraged engagement and led to a perceived improvement in pedagogic practices.
The Stock Market Valuation of Research and Development Expenditures

We examine whether stock prices fully reflect the value of firms' intangible assets, focusing on research and development (R&D). Since intangible assets are not reported on financial statements under current U.S. accounting standards and R&D spending is expensed, the valuation problem may be especially challenging. Nonetheless we find that historically the stock returns of firms doing R&D on average matches the returns on firms with no R&D. For companies engaged in R&D, high R&D intensity has a distinctive effect on returns for two groups of stocks. Within the set of growth stocks, R&D-intensive stocks tend to out-perform stocks with little or no R&D. Companies with high R&D relative to equity market value (who tend to have poor past returns) show strong signs of mis-pricing. In both cases the market apparently fails to give sufficient credit for firms' R&D investments. Our exploratory investigation of the effects of advertising on returns yields similar results. We also provide evidence that R&D intensity is positively associated with return volatility, everything else equal. Insofar as the association reflects investors' lack of information about firms' R&D activity, increased accounting disclosure may be beneficial.
Timing Performance Error in Rewarded and Non-Rewarded Tasks

The literature on human and nonhuman animal interval timing disagrees about whether perceived time is a linear or power function of real time, and to what extent reward influences timing performance. Two competing computational learning and timing models, Temporal Difference (TD, Schultz, 2013) and Sometimes Competing Retrieval (SOCR, Stout & Miller, 2007) are reviewed. The present experiments investigate human interval timing error in both reward and non-reward conditions. The experiments were simulated by a computational model to identify both the function that describes the effect of interval duration on the distribution of variance (e.g., scalar or linear) and the relative predictive power of the SOCR and TD models, and the effects of reward on interval timing. Specifically, it was hypothesized that 1) timing variability is scalar, not linear, 2) that a modified SOCR model explains the data, and 3) that interval timing performance is less variable in rewarding situations than in non-rewarding situations. Timing trials involved the presentation of a reference duration; participants then produced their estimate of that duration while under cognitive load (random number generation and serial math tasks) through key presses on a computer. The results failed to support these hypotheses. However, reward produced a nonsignificant tendency towards early responding. Finally, suggestions for further research, including further computational modeling and investigation of the neural substrata of reward and timing are discussed. SCALAR TIMING ERROR vi
Carbon fractionation in photo-dissociation regions

We upgraded the chemical network from the UMIST Database for Astrochemistry 2006 to include isotopes such as ^{13}C and ^{18}O. This includes all corresponding isotopologues, their chemical reactions and the properly scaled reaction rate coefficients. We study the fractionation behavior of astrochemically relevant species over a wide range of model parameters, relevant for modelling of photo-dissociation regions (PDRs). We separately analyze the fractionation of the local abundances, fractionation of the total column densities, and fractionation visible in the emission line ratios. We find that strong C^+ fractionation is possible in cool C^+ gas. Optical thickness as well as excitation effects produce intensity ratios between 40 and 400. The fractionation of CO in PDRs is significantly different from the diffuse interstellar medium. PDR model results never show a fractionation ratio of the CO column density larger than the elemental ratio. Isotope-selective photo-dissociation is always dominated by the isotope-selective chemistry in dense PDR gas. The fractionation of C, CH, CH^+, and HCO^+ is studied in detail, showing that the fractionation of C, CH and CH^+ is dominated by the fractionation of their parental species. The light hydrides chemically derive from C^+, and, consequently, their fractionation state is coupled to that of C^+. The fractionation of C is a mixed case depending on whether formation from CO or HCO^+ dominates. Ratios of the emission lines of [C II], [C I], ^{13}CO, and H^{13}CO^+ provide individual diagnostics to the fractionation status of C^+, C, and CO.
Analyzing U.S. nurse turnover: Are nurses leaving their jobs or the profession itself?

Objective: To examine and compare factors associated with making the decision to vacate a job (organizational turnover) versus leaving the profession (professional turnover) among registered nurses (RN) in the United States (U.S.). Methods: Nationally representative data from the 2008 National Sample Survey of Registered Nurses was used. The sample consisted of 8,796 RNs who held an active RN license as of March 10, 2008, but changed a place of work or left the profession entirely. The analysis has been performed using SAS, version 9.3. Results: The results of binary logistic regression revealed that RNs who reported work-related disability (OR = 14.51; p -value: < .001), illness (OR = 3.32; p -value: < .001), experienced high physical demands (OR = 1.57; p -value: < .001) or burnout (OR = 1.39; p -value: < .001), were unsatisfied with their schedule (OR = 2.16; p -value: < .001), or staffing arrangements (OR = 1.41; p -value: < .001) were more likely to leave the profession. Whereas RNs who reported high levels of stress (OR = 0.59; p -value: < .001) were unsatisfied with the organization’s leadership (OR = 0.22; p -value: < .001), unsatisfied with their opportunity to advance their career (OR = 0.56; p -value: < .001), or were not adequately compensated (OR = 0.63; p -value: < .001), were more likely to leave the organization. Conclusions: Policy makers and health care managers should be aware of the different factors that are associated with RNs’ decision to leave the profession or an organization. Health care managers involved in the development of nurse retention strategies should address organizational leadership and consider development of comprehensive career development programs. Policy makers should consider allocating additional resources to ensure that RN workforce is of adequate size, is qualified, and is able to provide high quality care in the U.S.
Local Variability in the Sagittae Otolith Shape of Mugil cephalus from the Sea of Tabarka and the Dam of Nebeur in Tunisia

The otolith shape analysis is a powerful tool to use in studies focusing to marine biology and ecology in various aquatic areas (marine, dam and lagoons) as well the identification of fish stocks of species. In the present study, the sagittae otoliths were used to compare specimens of Mugil cephalus collected from two Tunisian regions, Tabarka Sea and Nebeur Dam. We analyzed the shape variation by sex (male and female) and otolith side (left and right) in order to discriminate the stock structure of Mugil cephalus. Discriminant analysis demonstrated statistical differences in the otolith shape between specimens of two sampling sites, which indicate a clear population differentiation. Also, these results were confirmed by highly statistically significant difference between otoliths’ shape (left and right) for both sexes. Hence, the shape variability of otolith between these two sampling sites is probably correlated with local environmental factors.
CADP: A Novel Dataset for CCTV Traffic Camera based Accident Analysis

This paper presents a novel dataset for traffic accidents analysis. Our goal is to resolve the lack of public data for research about automatic spatio-temporal annotations for traffic safety in the roads. Through the analysis of the proposed dataset, we observed a significant degradation of object detection in pedestrian category in our dataset, due to the object sizes and complexity of the scenes. To this end, we propose to integrate contextual information into conventional Faster R-CNN using Context Mining (CM) and Augmented Context Mining (ACM) to complement the accuracy for small pedestrian detection. Our experiments indicate a considerable improvement in object detection accuracy: +8.51% for CM and +6.20% for ACM. Finally, we demonstrate the performance of accident forecasting in our dataset using Faster R-CNN and an Accident LSTM architecture. We achieved an average of 1.684 seconds in terms of Time-To-Accident measure with an Average Precision of 47.25%. Our Webpage for the paper is https://goo.gl/cqK2wE
Effects of a partially closed area in the North Sea (“plaice box”) on stock development of plaice

The ‘‘plaice box’’ is a partially closed area in the North Sea, established in 1989 to reduce the discarding of undersized plaice (Pleuronectes platessa) in the main nursery areas, and thereby to enhance recruitment to the fishery. In contrast to the expected positive effects, yield and spawning stock biomass have decreased. The effects of the plaice box are evaluated by analyzing the relevant factors and processes (natural and anthropogenic) that affect recruitment. It is shown that the Dutch beam trawl effort has decreased in two phases. During 1989–1993, when the plaice box was closed only during the second and third quarter, effort was reduced to around 40% of the original level. When the box was also closed in the fourth (1994) and first quarter (1995 onwards), effort decreased to around 6%. The effort reduction would imply a reduction in discard mortality if all other factors had remained constant. However, a reduced growth rate and possibly a higher rate of natural mortality may have counteracted the reduction in fishing effort. The apparent changes in growth and mortality coincided with changes in the North Sea ecosystem that occurred in the early 1990s but may also be related to a response to the change in beam trawl effort. 2000 International Council for the Exploration of the Sea
THE PROBLEM OF INCENTIVES IN BUILDING CORPORATE GOVERNANCE MODELS

The attempt to align interests of executives with those of shareholders has been addressed in the corporate governance context from a predominantly economic outlook based on the agency theory. The models that combine monitoring and control systems in association with financial incentive mechanisms, such as profit and income sharing, stock options, bonds and other benefits, consider an individual to be individualist, opportunist and self-interested, diverging from the assumptions of other theories and contemporary ideas in the area of human resources management. Based on the criticism related to the agency theory, particularly when drawing up incentive schemes, this article aims to look at alternative theories to build corporate governance practices that include considerations on extrinsic and intrinsic motivation of agents.
From National Service to Global Player: Transforming the Organizational Logic of a Public Broadcaster

We present organizational logics as a meso-level construct that lies between institutional theory's field-level logics and the sense-making activities of individual agents in organizations. We argue that an institutional logic can be operationalized empirically using the concept of a discourse – that is, a coherent symbolic system articulating what constitutes legitimate, reasonable, and effective conduct in, around, and by organizations. An organization may, moreover, be simultaneously exposed to several institutional logics that make up its broader ideational environment. Taking these three observations together enables us to consider an organizational logic as a spatially and temporally localized configuration of diverse discourses. We go on to show how organizational logics were transformed in the Australian Broadcasting Corporation between 1953 and 1999 by examining the changing discourses that appeared in the Corporation's annual reports. We argue that these discourses were modified through three main forms of discursive agency: (1) undertaking acts of ironic accommodation between competing discourses; (2) building chains of equivalence between the potentially contradictory discourses; and (3) reconciling new and old discourses through pragmatic acts of ‘bricolage’. We found that, using these forms of discursive agency, a powerful coalition of actors was able to transform the dominant organizational logic of the ABC from one where the Corporation's initial mission was to serve national interests through public service to one that was ultimately focused on participating in a globalized media market. Finally, we note that discursive resources could be used as the basis for resistance by less powerful agents, although further research is necessary to determine exactly how more powerful and less powerful agents interact around the establishment of an organizational logic.
National populism and gendered vigilantism: The case of the Soldiers of Odin in Finland

Based on a discursive analysis of various media reports published in 2015–2018 by and about the Finnish right-wing street patrolling organization Soldiers of Odin (SOO), we explore the gendered dimension of contemporary vigilantism. We find that street patrolling as a practice of vigilantism, is justified in this case by using representations of the cityspace as a place of friction between locals and newcomers and of the street as a locus for enacting gendered and racial/ethnic identities. Our findings suggest that SOO’s vigilant practices exhibit a mixture of traditional and new features of masculinity. We argue that the activities of anti-immigration groups such as the SOO in Finland demonstrate a feminist security dilemma concerning the way securitization of public gender-based violence is used to enhance militarized performance of white masculinity. We identify four recurring themes that are used by group members to portray themselves as part of a legitimate social movement: protective masculinity, militarized masculinity, supplement of the state, and indigenous masculinity.
Translanguaging in mainstream education: a sociocultural approach

ABSTRACT Due to the monolingual self-understanding of European nation-states, migration-induced multilingualism and the language mixing practices it triggers are not usually acknowledged as resources for learning within mainstream classrooms. The term translanguaging has recently been put forward as both a way of describing the flexible ways in which bilinguals draw upon their multiple languages to enhance their communicative potential and a pedagogical approach in which teachers and pupils use these practices for learning. However, little research has been conducted in how the translanguaging approach can be used in mainstream education to enhance knowledge. This study draws on videographic data recorded in 59 10th grade (15-year-olds) subject-matter classes in 4 secondary schools. Applying sociocultural discourse analysis to peer–peer interaction and therefore considering how learners scaffold one another as they participate in collaborative talk and in the co-construction of knowledge, results describe several functions of translanguaging for ‘exploratory talk’ leading to content-matter learning. Multilingual adolescents in naturalistic settings thus use their multilingualism to cognitively engage with content-based tasks and produce high-order speech acts embedded in complex talk.

EXAMINING TEACHER CREDIBILITY AND LANGUAGE ACHIEVEMENT IN LIGHT OF EMOTIONALIZATION AND LIFE SYLLABUS

Given the significance of teacher credibility and its impacts on learning and teaching processes, the present study aims to investigate whether there are any significant relationships between teacher credibility, and the two newly-developed concepts (i.e., emotionalization and life syllabus) in relation to achievement scores of English as a Foreign Language (EFL) learners. To this end, 300 EFL learners were asked to take teacher credibility, emotionalization, and life syllabus scales. Structural Equation Modeling (SEM) was utilized to examine the probable relationships. Findings revealed that exvolvement, as a component of emotioncy, can lead to higher achievement scores, while involvement, as another component of emotioncy hierarchy, brings about the opposite results. Furthermore, the findings indicated that higher rates of teacher credibility can lead to higher achievement scores. It was also revealed that life syllabus and emotionalization increase teacher credibility although they do not affect achievement scores directly. Finally, the results were discussed, and some suggestions were made for future studies in the realm of language education.
Questions arising from the use of peer assisted learning as a technique to increase diverse participation in engineering education

A program of peer assisted study sessions (PASS) was piloted in the second half of 2010 in two first year engineering courses catering to both on-campus and distance students. The student cohort concerned is a diverse cohort of students, a large percentage of whom are non-traditional higher education students accessing the course through distance education. The PASS program was implemented in both traditional face to face on campus sessions as well as in an online mode, which was intended to partially address issues of inclusivity and access to peer support for this diverse cohort.
Validity of the Local Approximation in Iron- Pnictides and Chalcogenides

We introduce a cluster DMFT (Dynamical Mean Field Theory) approach to study the normal state of the iron pnictides and chalcogenides. In the regime of moderate mass renormalizations, the self-energy is very local, justifying the success of single site DMFT for these materials and for other Hunds metals. We solve the corresponding impurity model with CTQMC (Continuous Time Quantum Monte-Carlo) and find that the minus sign problem is not severe in regimes of moderate mass renormalization.
The association between participation in organised physical activity and level of physical activity and inactivity in adolescent girls

Background: An increase of leisure time and vigorous physical activity (PA) in girls can be supported by their regular participation in organised PA, as it brings numerous health benefits and is an important part of healthy lifestyle. Objective: This study aimed to examine whether there are differences in physical activity and inactivity structure and levels in girls who do not participate in any organised PA and girls who regularly participate in physical education or training classes. Methods: The sample comprised 497 girls (age 17.94 ± 0.52 years) from Poland participating never (group 1), or once (group 2), twice (group 3), and three or four times (group 4) a week in any organised PA. The Polish version of the International Physical Activity Questionnaire (IPAQ), accelerometer ActiGraph GT1M and activity and inactivity logs were used to assess the level and structure of physical activity and inactivity. Results: Girls participating in organised PA three or more times a week showed significantly the highest values of steps/day, moderate and vigorous PA, and leisure time PA, but also inactivity in comparison to girls without participation in organised PA. Conclusions: This study provides the evidence supporting the positive link between a number/week participation in organised PA and PA level. However, the findings from this study also advocate the need of increasing PA and reducing inactivity in girls in school or after-school periods, regardless of the participation in organised PA.

Documenting the Brain Drain of “La Crème de la Crème”

Summary Most of the recent literature on the effects of the brain drain on source countries consists of theoretical papers and cross-country empirical studies. In this paper we complement the literature through three case studies on very different regional and professional contexts: the African medical brain drain, the exodus of European researchers to the United States, and the contribution of the Indian diaspora to the rise of the IT sector in India. While the three case studies concern the very upper tail of the skill and education distribution, their effects of source countries are contrasted: clearly negative in the case of the exodus of European researchers, clearly positive in the case of the Indian diaspora’s contribution to putting India on the IT global map, and mixed in the case of the medical brain drain out of Africa.
