Performance impacts of is at the individual level: An integrated model

In this paper, we propose an integrated model that explains performance impacts of IS at the individual level. We include nature of IS use, task-technology-fit and IS use as determinants of performance impacts of IS at the individual level. Based on data from 434 respondents from different functional areas in six different organizations, we empirically validate the integrated model for an individual IS productivity application. Our results indicate that integrated model explains nearly 60% of the variance in performance impacts of IS at the individual level. Overall, the results provide support to our position that the integrated model provides a fuller understanding of performance impacts of IS at the individual level by including both task-technology-fit and nature of IS use, an aspect not addressed in the extant IS literature. The theoretical contribution of this research lies in the development of a model for performance impacts of IS that has significantly higher explanatory power than the existing models.
Synthesis of the New Ring System Bispyrido[4',3':4,5]pyrrolo[1,2-a:1',2'-d]pyrazine and Its Deaza Analogue

Derivatives of the new ring systems bispyrido[4',3':4,5]pyrrolo[1,2-a:1',2'-d]pyrazine-6,13-dione and its deaza analogue pyrido[4'',3'':4',5']pyrrolo-[1',2':4,5]pyrazino[1,2-a]indole-6,13-dione were conveniently synthesized through a four-step sequence. Symmetrical derivatives of the former ring system were obtained through self condensation. On the other hand, condensation of 6-azaindole carboxylic acid with indole 2-carboxylic acid afforded the deaza analogue ring system. Derivatives of the title ring system were tested by the National Cancer Institute (Bethesda, MD, USA) and four of them exhibited modest activity against MCF7 (a breast cancer cell line) and/or UO-31 (a renal cancer cell line).
The Genesis of Transactional Strategies Instruction in a Reading Program for At-Risk Students

This article describes the problem-solving response of the staff in a large public school system to at-risk students' low achievement and lack of access to the district's enriched reading/language arts curriculum. The staff developed a theory-based, supplemental reading program in cognitive learning strategies to replace remediation for at-risk students and called it SAIL (Students Achieving Independent Learning). The article illustrates the use of current cognitive research in program design and development and describes instruction and training in the program. Instruction starts with explicit teaching of a repertoire of learning strategies during instruction in reading comprehension. It becomes more student centered and refined until it evolves into transactional strategies instruction, a blend of explicit instruction, direct explanation, reader response, and teacher-student-text interactions. Training takes 3-5 years, with the first year being crucial to teacher and, consequently, student success.
Finite size scaling for the core of large random hypergraphs

The (two) core of an hyper-graph is the maximal collection of hyper-edges within which no vertex appears only once. It is of importance in tasks such as efficiently solving a large linear system over GF[2], or iterative decoding of low-density parity-check codes used over the binary erasure channel. Similar structures emerge in a variety of NP-hard combinatorial optimization and decision problems, from vertex cover to satisfiability. For a uniformly chosen random hyper-graph of m = nρ vertices and n hyper-edges, each consisting of the same fixed number l ≥ 3 of vertices, the size of the core exhibits for large n a first order phase transition, changing from o(n) for ρ > ρc to a positive fraction of n for ρ 0. Analyzing the corresponding ‘leaf removal’ algorithm, we determine the associated finite size scaling behavior. In particular, if ρ is inside the scaling window (more precisely, ρ = ρc + r n −1/2 ), the probability of having a core of size �(n) has a limit strictly between 0 and 1, and a leading correction of order �(n −1/6 ). The correction admits a sharp characterization in terms of the distribution of a Brownian motion with quadratic shift, from which it inherits the scaling with n. This behavior is expected to be universal for wide collection of combinatorial problems.
Lung transplantation in patients with scleroderma: case series, review of the literature, and criteria for transplantation

Abstract: Backgrounds: The use of lung transplantation (LTX) to treat respiratory failure because of scleroderma is controversial. We present our experience, review the current literature, and suggest specific criteria for LTX in scleroderma. Of the 174 patients who underwent LTX at our center, seven (4%) had scleroderma‐associated respiratory failure.
Tracking global changes induced in the CD4 T-cell receptor repertoire by immunization with a complex antigen using short stretches of CDR3 protein sequence

The clonal theory of adaptive immunity proposes that immunological responses are encoded by increases in the frequency of lymphocytes carrying antigen-specific receptors. In this study, we measure the frequency of different TcRs in CD4+ T cell populations of mice immunized with a complex antigen, killed Mycobacterium tuberculosis, using high throughput parallel sequencing of the TcR beta chain. In order to track the changes induced by immunisation within this very heterogeneous repertoire, the sequence data were classified by counting the frequency of different clusters of short (3 or 4) continuous stretches of amino acids within the CDR3 repertoire of different mice. Both unsupervised (hierarchical clustering) and supervised (support vector machine) analysis of these different distributions of sequence clusters differentiated between immunised and unimmunised mice with 100% efficiency. The CD4+ T cell receptor repertoires of mice 5 and 14 days post immunisation were clearly different from that of unimmunised mice, but were not distinguishable from each other. However, the repertoires of mice 60 days post immunisation were distinct both from unimmunised mice, and the day 5/14 animals. Our results reinforce the remarkable diversity of the T cell receptor repertoire, resulting in many diverse private TcRs contributing to the T cell response even in genetically identical mice responding to the same antigen. Finally, specific motifs defined by short sequences of amino acids within the CDR3 region may have a major effect on TcR specificity. The results of this study provide new insights into the properties of the CD4+ adaptive T cell response.
Researching the Contested Place of Reflective Practice in the Emerging Culture of Performativity in Schools: Views from the Republic of Ireland

This article examines the role of reflective practice in a growing culture of new managerialism and performativity which has emerged in schools in the Republic of Ireland over recent years. Ten student teachers participating in a Postgraduate Diploma in Education and 24 experienced teachers participating in a Master's in Education programme participated in the study. Through a series of open-ended questionnaires and focus group discussions, these teachers' experiences of the evaluative framework which now typifies schooling in Ireland, and their capacity within this paradigm to engage in critical reflection, were examined. The study comments on the extent to which meaningful reflection can be part of a performance-driven agenda, and examines the implications of performativity cultures for initial teacher education and teacher professional development.
Predicting outcomes of inpatient psychotherapy using quality management data: comparing classification and regression trees with logistic regression and linear discriminant analysis

Abstract Three classification models are compared with regard to their ability to identify unsuccessful treatment outcomes. Data from the Stuttgart-Heidelberg model on quality management of 1,401 inpatients were used. According to the evaluation algorithm used, 82% benefited from therapy. Outcomes were classified using logistic regression, linear discriminant analysis, and classification and regression trees. For the regression techniques, variables were selected stepwise backward; for the CART model, the method-inherent selection scheme was adopted. Because there were few signal cases in the data, these cases were double weighted. Model performance was obtained using classic cross-validation. Overall misclassification rates did not differ between methods for the construction sample but differed when applied to the validation sample. Overall classification rates for the given problem are modest.
Solar neutrinos: Global analysis and implications for SNO

We present a global analysis of all the available solar neutrino data treating consistently the 8B and hep neutrino fluxes as free parameters. The analysis reveals at 99.7% C.L. eight currently-allowed discrete regions in two-neutrino oscillation space, five regions corresponding to active neutrinos and three corresponding to sterile neutrinos. Most of the allowed oscillation solutions are robust with respect to changes in the analysis procedures, but the traditional vacuum solution is fragile. The globally-permitted range of the 8B neutrino flux, 0.45 to 1.95 in units of the BP2000 flux, is comparable to the 3σ range allowed by the standard solar model. We discuss the implications for SNO of a low mass, Δm2 ~ 6 × 10−12 eV2, vacuum oscillation solution, previously found by Raghavan, and by Krastev and Petcov, but absent in recent analyses that included Super-Kamiokande data. For the SNO experiment, we present refined predictions for the charged-current rate and the ratio of the neutral-current rate to charged-current rate. The predicted charged-current rate can be clearly distinguished from the no-oscillation rate only for the LMA solution. The predicted ratio of the neutral-current rate to charged-current rate is distinguishable from the no-oscillation ratio for the LMA, SMA, LOW, and VAC solutions for active neutrinos.
Negative Relationships Between Self-Efficacy and Performance Can Be Adaptive: The Mediating Role of Resource Allocation

This research speaks to the ongoing debate regarding the role of self-efficacy in self-regulation. Specifically, we argue that both positive and negative relationships between self-efficacy and resource allocation are part of an adaptive process. We present the results of two empirical studies demonstrating that a negative relationship between self-efficacy and resource allocation is not always maladaptive and, in fact, can lead to positive indirect effects on performance. In Study 1, we observed natural fluctuations in self-efficacy as individuals completed a mathematics test, finding that the tendency to reduce resource allocation with high self-efficacy is most clearly observed when time is scarce. In turn, an inverted-U relationship between resource allocation and overall performance under high time scarcity emerged such that moderate levels of resource allocation resulted in the highest levels of performance. Study 2 used an experimental design in which self-efficacy was manipulated. Replicating core findings from Study 1, individuals drew upon self-efficacy to balance resource allocation across competing demands. We conclude with a discussion of the theoretical and practical implications of our results.
Age and gender differences in medical adherence after myocardial infarction: Women do not receive optimal treatment – The Netherlands claims database

Background Following myocardial infarction, medication is, besides lifestyle interventions, the cornerstone treatment to improve survival and minimize the occurrence of new cardiovascular events. Still, data on nationwide medication adherence are scarce. This study assesses medical adherence during one year following myocardial infarction, stratifying per type of infarct, age and gender. Design Retrospective cohort study. Methods In The Netherlands, all inhabitants are by law obliged to have health insurance and all claims data are centrally registered. In 2012 and 2013, all national diagnosis-codings of ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) were acquired. Furthermore, information on retrieved medication was extracted from the Dutch Pharmacy Information System. Twelve months after discharge, the retrieved medication at the pharmacy of each pharmacological therapy (aspirin-species, P2Y12-inhibitor, statin, beta-blocker, angiotensin-converting enzyme-/angiotensin 2-inhibitor, vitamin-K antagonists or novel oral anticoagulant) were analysed. Results In total, 59,534 patients (67 ± 13 years, 39,545 (66%) male, 57% NSTEMI) were included, of whom 52,672 (88%) patients were analysed for one-year medical adherence. STEMI patients more often achieved optimal medical adherence than NSTEMI patients (60% vs. 40%, p ≤ 0.001). In both STEMI and NSTEMI, use of all five indicated drugs was higher in male patients compared with female (STEMI male 61% vs. female 57%, p ≤ 0.001; NSTEMI male 43% vs. female 37%, p ≤ 0.001. With increasing age, a gradual decrease was observed in the use of aspirin, P2Y12-inhibitors and statins. Conclusion Age and gender differences existed in medical adherence after myocardial infarction. Medical adherence was lower in women, young patients and elderly patients, specifically in NSTEMI patients.
Effects of entertainment media framing on support for gay rights in China: Mechanisms of attribution and value framing

This study investigates the framing effects of gay-themed entertainment media in China. Specifically, the study explores the mechanisms underlying attribution framing and value framing, through two separate experiments. The results of the first experiment indicate that exposure to attribution frames had considerable influence on the participants' perceptions of the controllability of homosexuality and their emotional responses. In addition, fictional entertainment media's framing of the origin of homosexuality indirectly influenced the participants' opinion through anger. Those participants exposed to a program homosexuality as a type of ‘controllable’ sexuality were likely to express anger and thus were not likely to support gay rights. The results of the second experiment indicate that the core values reflected in a gay-themed program affected the participants' opinions by changing their perception of the importance of value-related beliefs. Those participants exposed to a frame reflecting family values were likely to consider beliefs about family values to be important, which facilitated their support for gay people's personal dignity and equal rights to jobs, housing, and freedom of expression, among others.
VR Cue-Exposure Treatment For Bulimia Nervosa

Several approaches to the treatment of bulimia nervosa have proved effective, including cognitive-behavioral therapy; however, not all patients improve. It is therefore necessary to explore the possibilities of increasing the efficacy of such treatments. One way to attempt this is to incorporate new technologies. This review explores the possibility of developing a new, empirically validated procedure for the treatment of bulimia nervosa patients that involves cue exposure via virtual reality.
Mining StackOverflow to Filter Out Off-Topic IRC Discussion

Internet Relay Chat (IRC) is a commonly used tool by Open Source developers. Developers use IRC channels to discuss programming related problems, but much of the discussion is irrelevant and off-topic. Essentially if we treat IRC discussions like email messages, and apply spam filtering, we can try to filter out the spam (the off-topic discussions) from the ham (the programming discussions). Yet we need labelled data that unfortunately takes time to curate. To avoid costly cur ration in order to filter out off-topic discussions, we need positive and negative data-sources. On-line discussion forums, such as Stack Overflow, are very effective for solving programming problems. By engaging in open-data, Stack Overflow data becomes a powerful source of labelled text regarding programming. This work shows that we can train classifiers using Stack Overflow posts as positive examples of on-topic programming discussion. You Tube video comments, notorious for their lack of quality, serve as training set of off-topic discussion. By exploiting these datasets, accurate classifiers can be built, tested and evaluated that require very little effort for end-users to deploy and exploit.
Principal evaluation: New directions for improvement

Together with parents and teachers, school principals play crucial roles in the effective education of America's children and youth. In recent years, researchers and policymakers have supported what parents and teachers have long known experientially-that the quality of leadership provided by school principals significantly influences the quality of schools (Andrews & Soder, 1987; Bossert, Dwyer, Rowan, & Lee, 1982; Clinton, 1991; Duke, 1987, 1992; Greenfield, 1987; Hallinger & Murphy, 1987; Leithwood, 1988; Schmitt & Schechtman, 1990; Sergiovanni, 1987). Consequently, systematic and careful evaluation of principal qualifications, competence, and performance is critically important to the success of America's elementary and secondary schools. The public interest is no less at risk from incompetent school principals than from incompetent doctors, lawyers, and accountants, and all such public servants should be carefully evaluated throughout their professional careers. Sound evaluations of the aptitudes, proficiencies, performance, and special achievements of principals not only protect the public from poor
Exposure to the social sharing of emotion: Emotional impact, listener responses and secondary social sharing

In line with evidence showing that emotion involves a social sharing process in which the subject communicates about emotional experience, this article examines the impact of being exposed to such communications. First, it was predicted that being exposed to the social sharing of an emotion is emotion-inducing. Second, it was reasoned that if this holds true, then the listener should later engage in socially sharing with other persons the emotional narrative heard. Thus, a process of ‘secondary social sharing’ was predicted. In two independent studies subjects recalled a situation in which someone had shared an emotional experience with them. They then rated emotions felt while exposed to the narrative, responses adopted toward the sharing person, and extent of secondary social sharing. The predictions were supported. Exposure to a social sharing situation was confirmed as itself emotion-inducing. Secondary social sharing was recorded in 66 per cent of the cases in Study 1 and in 78 per cent in Study 2. Both studies also showed that exposure to the sharing of highly intense emotional episodes elicited more repetitive secondary social sharing and a superior number of target persons than exposure to episodes of low or of moderate emotional intensity. © 1997 by John Wiley & Sons, Ltd.
Is ASEAN powerful? Neo-realist versus constructivist approaches to power in Southeast Asia 1

Abstract This paper asks: ‘is ASEAN powerful? ’ The argument is made that there is a divide over this question between two broad groups of scholars who are referred to as ‘neo-realists’ (including realists) and ‘constructivists’. Focusing attention on this question is useful because it helps to bring into view three, not always explicit, points of argument between constructivists and neo-realists in their assessments of ASEAN. First, the two groups draw different empirically based conclusions about ASEAN's efficacy in East Asian affairs. Neo-realists are generally sceptical about the Association's role in the region because they view it, along with multilateral organizations more generally, as peripheral to great power politicking, what they see as the real stuff and substance of international affairs. A second, conceptual, point of argument is over understandings of power. For neo-realists, power is frequently used interchangeably with force and coercion. Scholars influenced by social constructivist ideas offer a challenge to this equation of power and dominance on the grounds that power is neither necessarily negative-sum nor limited to conflictual situations. Third, we suggest that closely related arguments are marshalled by both sides in debates over ASEAN's future role and organizational structure. Neo-realists argue that a shift to a more rules-based institutional form is in order, while constructivists place their emphasis on identity building.
Climbing walls, making bridges: children of immigrants’ identity negotiations through capoeira and parkour in Turin

Capoeira and parkour are two different body practices which have gained worldwide attention in urban settings in the last few decades. The following paper will explore how capoeira and parkour relate to the construction of identity paths amongst children of immigrants between 12 and 20 in Turin, Italy. It will do so by looking at how such practices are used by young men of migrant origin to negotiate and perform narratives of self-worth, belonging and recognition within marginalising and excluding urban environments. This study acknowledges that social identifications are created, negotiated and (re)produced through bodily and spatial means and within networks of power relations. Following this premise, the insights proposed in this paper suggest that the ambivalent and fluid use of bodies and spaces implied by capoeira and parkour can represent a meaningful lens to understand the embodied and spatial identity negotiations enacted by participants in their daily lives. This theoretical perspective will ill.
Sign Stability for Switched Linear Systems and Its Application in Flight Control

The sign stability concept in ecological systems is introduced into the analysis and synthesis of switched linear system to explore new control design technique. The necessary and sufficient condition for sign stability of a switched linear system under arbitrary switching is achieved via the notion of complete isogenous sign stable set (CISSS). A new approach for the stabilization of switched system is presented. Although the controllers are devised for each subsystem, respectively, the switched system is sign stabilized by the constitution of CISSS. The provided method has natural robustness and more design freedoms than the familiar Lyapunov function method, which bears relative conservativeness as the requirement of solving LMIs. The presented technique is validated by an example of flight control within a large-scale flight envelop. Simulation results indicate that the proposed method can stabilize the flight attitude under large variations of system parameters and external perturbations.
Community Engagement for Student Learning in Geography

This article examines the role and purpose of community engagement as a learning and teaching strategy within higher education geography. It explores different interpretations of the concept of community engagement and illustrates different examples of this kind of learning through six case studies drawn from Australia, New Zealand, the UK, and the USA. Key factors which can lead to success in community engagement and also some of the risks and challenges are discussed. Geographers are encouraged to become involved in this kind of experiential learning and to share practice across a wide range of institutions and countries.
