Team identification: a determining factor of performance

Purpose – This study seeks to explore why some teams realize performance gains and others do not. Team identification is proposed as an explanatory mechanism of performance.Design/methodology/approach – Data from two longitudinal studies with 42 teams (270 individuals) are examined using regression analysis. Study 1 relies on student teams, while Study 2 is based on two field samples of actual working teams. In both studies, team identification was captured prior to the objective performance measures.Findings – This study empirically provides evidence that team identification is linked to team performance across three settings.Research limitations/implications – Although the sample size is relatively small within each study, the implications are that team process variables such as identification matter when gauging performance across all three settings.Practical implications – It is critical that team‐oriented processes, such as identification, are promoted if managers hope to see performance gains within.
Distribution, karyomorphology, and morphology of Aspidistra subrotata (Asparagaceae) at different ploidy levels in limestone areas of Asia

Abstract Aspidistra subrotata Y. Wan & C.C. Huang, 1987 is considered for the first time as a widespread polyploidy complex in the genus Aspidistra Ker Gawler, 1823 from limestone areas of Asia. The chromosome number of the tetraploid is 2n = 76 and the karyotype is formulated as 2n = 44 m + 8 sm + 24 st, while the chromosome number of the diploid is 2n = 38 and the karyotype formula 2n = 22 m + 4 sm + 12 st. In our studies, diploids occupy broader geographical and environmental niche spaces than tetraploids. Although the leaf-shape of Aspidistra subrotata varies quantitatively between and within diploid and/or tetraploid population(s), no obvious discontinuity in the width of leaf has been observed. The tetraploid plants may be distinguished from the diploid plants by their rigid petioles as well as thick deep green lamina. Aspidistra subrotata is therefore an interesting material to explore the formation and the evolutionary dynamics of a natural polyploid complex from limestone areas of the tropical regions.
TEACHING MEDICAL SOCIOLOGY THROUGH FILM: THEORETICAL PERSPECTIVES AND PRACTICAL TOOLS*

This article sets an agenda for the teaching of medical sociology by providing a pedagogical approach and set of tools that can be used in the classroom. Specifically, I argue that we need to push our students away from dualistic or relativistic thinking toward the ability to apply the sociological perspective in health, illness, and healing and to understand its limits as well as its promise. This type of teaching can be accomplished through a style that requires students to actively participate in the classroom. One way to do this, particularly in large classes where other strategies are not feasible, is to use feature films as "cases. " The key advantage to this teaching strategy lies in its critical match with current students' high visual literacy. Ifocus on three substantive topics: mental illness, death-dying and the political economy of illness. I supply details on films and support materials. The appendix provides a short annotated list of otherfilms (and other resources) available on both these and a variety ofother medical topics.
Correlates of Depression Among HIV-Positive Women and Men Who Inject Drugs

Introduction:Although depression is common among HIV-positive injection drug users (IDUs), little is known about differences between male and female HIV-positive IDUs. Methods:We used baseline data for 1126 HIV-positive IDUs from a behavioral intervention trial from 2001 through 2005 in 4 US cities. Using the Brief Symptom Inventory-18, scores indicating high risk for depression were calculated separately for men and women based on raw scores of 9 for women and 7 for men. We did separate logistic regressions for men and women to evaluate correlates of depression in 4 domains: sociodemographic, psychosocial, substance use, and sexual behaviors/attitudes. Results:Approximately one third of women and men met the criteria for being at high risk of depression. Women reported significantly more depressive symptoms than men. Correlates linked with depression for both genders included perceived functional limitation, greater negative feelings regarding condom use, lower social support, and lower sense of empowerment. Being physically abused as adults and being Hispanic were correlates specific to men. No unique correlate was identified for women. Discussion:Because of the high prevalence of depression among HIV-positive IDUs, caregivers should screen HIV-positive IDUs for depression and consider treatment for depression. Because of the similarities in correlates of depression among men and women, case finding and interventions for depression are likely to be similar for male and female HIV-positive IDUs.
From Opinion-Based to Evidence-Based Social Work: The Swedish Case

This article presents an account of Sweden’s Institute for Evidence-Based Social Work Practice (IMS), located in Stockholm, Sweden. The article places IMS in the context of making Swedish social care services less opinion-based and more evidence-based. The institute is an example of how policy-driven processes promote the use of evidence-based practices in this European nation. The article includes presentations of history, organization, and products of IMS, and concludes with comments on future opportunities and challenges.
Executive Stock Option Exercises and Inside Information

This article examines whether insiders use private information to time the exercises of their executive stock options. Before May 1991, insiders had to hold the stock acquired through option exercise for 6 months. Exercises from that regime precede significantly positive abnormal stock performance, suggesting the use of inside information to time exercises. By contrast, we find little evidence of such timing since insiders have been able to sell acquired shares immediately. Now, such timing should show up as negative abnormal stock returns after option exercise. However, we find negative stock performance only after exercises by top managers at small firms.
GM-CSF promoter chromatin remodelling and gene transcription display distinct signal and transcription factor requirements

Granulocyte-macrophage colony stimulating factor (GM-CSF) plays a key role in myeloid cell function and is rapidly and transiently expressed in T cells in response to immune or inflammatory stimuli. Induction of GM-CSF gene expression is accompanied by changes in chromatin structure across the proximal promoter region of the gene. We show that the promoter remodelling and subsequent gene transcription occurs with distinct signal and transcription factor requirements. Activation of the protein kinase C (PKC) signalling pathway is sufficient to induce changes in chromatin structure across the promoter, but both the PKC and calcium signalling pathways are required for efficient gene transcription. Although NFAT transcription factors contribute to GM-CSF gene transcription, they are not required for promoter remodelling. However, the presence of the nuclear factor-κB transcription factor, c-Rel, in the nucleus is strongly correlated with and required for the events of chromatin remodelling.
Photoaffinity labeling of benzodiazepine receptors causes altered agonist-antagonist interactions

Previous studies have shown that [3H]flunitrazepam forms irreversible cross-links with brain tissue when exposed to ultraviolet irradiation. Comparison of the amount of [3H]flunitrazepam irreversibly incorporated and the number of benzodiazepine binding sites blocked after photolabeling has indicated that several binding sites are inactivated for each molecule of [3H]flunitrazepam incorporated. To learn the cause of this discrepancy, binding to the benzodiazepine binding sites has been examined using several radiolabeled benzodiazepine antagonists. Binding of a beta-carboline ester, CGS-8216, and Ro 15–1788 was not altered by photolabeling; however, displacement studies revealed that photolabeling converted a homogeneous set of benzodiazepine binding sites into two subsets: one of high affinity (unaltered sites) and one of low affinity. The low affinity sites could be detected by displacement studies of antagonist binding by benzodiazepines, and conversion to a low affinity form accounts for the discrepancy observed after photolabeling using [3H]flunitrazepam as ligand.
A critical assessment of the synthesis and biological activity of p53/human double minute 2‐stapled peptide inhibitors

Helix stapling enhances the activity of peptides that interact with a target protein in a helical conformation. These staples are also supposed to change the pharmacokinetics of the molecules and promote cytoplasmic targeting. We assessed the extent to which the pharmacokinetic characteristics are a function of the staple for a peptide inhibiting the interaction of p53 with the human double minute 2 (Hdm2) protein and differ from those of the standard cationic cell‐penetrating peptide nona‐arginine.
RELATION OF OBJECT CURIOSITY TO PSYCHO- LOGICAL ADJUSTMENT IN CHILDREN'

During recent years there has been considerable research interest in the related topics of exploratory behavior, curiosity, and the tendency to seek and maintain novelty in perception. Most of the experiments in this general area have dealt with subhuman species: thus, Harlow and his collaborators (7, 8) have emphasized the importance of "curiosity-investigatory" motives in monkeys; and Montgomery and his associates (17, 18, 19) have demonstrated the motive power of what they term the "exploratory drive" in rats. There have been only a few studies concerned with curiosity in humans: Berlyne (1, 2, 3) investigated the stimulus factors related to curiosity in adults; Kagan, Sontag, Baker, and Nelson (o0) found IQ changes in children to be related to curiosity themes on the TAT; and one of us (14) presented tentative evidence that anxiety and curiosity are negatively related in psychiatric patients. For brief reviews of research in the whole area of exploratory behavior the reader is referred to Berlyne (4) and Butler (5). The manifest fact of curiosity in humans has been taken into account by many theorists, including James (9), McDougall (12), Troland (20), Linton (ii), Maslow (16), and the psychoanalysts (6). One of the present authors has proposed a conceptualization of human motivation which to a considerable degree is built around the tendency of individuals to seek novelty in their perception. This point of view, which is more fully described
Allocation trade-off under climate warming in experimental amphibian populations

Climate change could either directly or indirectly cause population declines via altered temperature, rainfall regimes, food availability or phenological responses. However few studies have focused on allocation trade-offs between growth and reproduction under marginal resources, such as food scarce that may be caused by climate warming. Such critical changes may have an unpredicted impact on amphibian life-history parameters and even population dynamics. Here, we report an allocation strategy of adult anuran individuals involving a reproductive stage under experimental warming. Using outdoor mesocosm experiments we simulated a warming scenario likely to occur at the end of this century. We examined the effects of temperature (ambient vs. pre-/post-hibernation warming) and food availability (normal vs. low) on reproduction and growth parameters of pond frogs (Pelophylax nigromaculatus). We found that temperature was the major factor influencing reproductive time of female pond frogs, which showed a significant advancing under post-hibernation warming treatment. While feeding rate was the major factor influencing reproductive status of females, clutch size, and variation of body size for females, showed significant positive correlations between feeding rate and reproductive status, clutch size, or variation of body size. Our results suggested that reproduction and body size of amphibians might be modulated by climate warming or food availability variation. We believe this study provides some new evidence on allocation strategies suggesting that amphibians could adjust their reproductive output to cope with climate warming.
A Method for Automating the Visual Inspection of Printed Wiring Boards

The application of pattern recognition techniques to manufacturing processes is a rapidly developing technology. Automatic verification of the quality of printed wiring boards (PWB's) using pattern recognition techniques is one potential application in this field. Qualitatively, this problem is finding small, irregular features in an environment of complicated, but larger and well-defined geometric features. In addition to the basic pattern recognition task, stringent performance requirements, both for throughput and accuracy, must be met if actual production usage is expected. The method employed in this study is based on characterizing 5 × 5 or 7 × 7 element binary patterns derived from the class of PWB's being inspected as good or defective. A database of 80 512 × 512 element images of PWB's was constructed and used to determine the number of unique patterns and their rates of occurrence. The major experimental result of this study is that less than 500 of the possible (15/16)224 5 × 5 patterns are needed to describe all the border containing patterns in the 80 images. It is also apparent that more patterns would be required if the training database was larger. The small number of patterns needed to represent virtually all of the normal border patterns suggests a two-stage inspection strategy. In the first stage, each border pattern from the PWB being inspected is compared to a previously prepared list.
Effects of a Self-Encouragement Program on Stress of Mothers of Children with Cancer Referred to Imam Ali Hospital, Zahedan, In 2015

Introduction: In addition to the physical problems for the patients themselves, cancer can cause several social and psychological problems to the family, especially the mother in pediatric cases. This study aimed to investigate the effects of a self-encouragement program on stress of mothers of children with cancer referred to Imam Ali Hospital of Zahedan in 2015. Materials and Methods: This case-control study was performed on 44 mothers with children suffering from cancer, referred to the hospital during October and November of 2015. Convenience sampling was used, and the mothers were randomly allocated into two 22-member groups. The Impact of Event Scale – Revised (IES-R) was the data collection instrument. Educational classes were held in the hospital. Confidentiality and mutual respect were observed by each and every member of the group. Data obtained before and after the intervention were analyzed using the independent t-test, paired t-test and ANOVA. The significance level was set at 0.05. Findings: The most frequent diseases were acute lymphoblastic leukemia (47%) and brain tumors (16%). The results indicated that the mean score of stress in the control group did not significantly between the two time points (P=0.106). In the intervention group, however, there was a significant difference in stress mean scores before (54.3±2.0) and after (37.1±1.8) the intervention (P<0.001). Conclusion: Self-encouragement can help mothers dealing with a diseased child to feel less stressed. Therefore, they may be able to act more effectively when faced with problems.
Experimental evidence for differential slowing in the lexical and nonlexical domains

Abstract Older and younger adults were tested on lexical and nonlexical tasks. When lexical and nonlexical processing were compared across equivalent ranges of task complexity, the degree of age-related slowing in the nonlexical domain was much larger than that observed in the lexical domain. to determine whether this nonlexical disadvantage is specific to older adults or whether it is characteristic of any slow individual, subgroups of fast older and slow young adults were matched on lexical processing speed. Older adults who were fast processors of lexical information were much slower at processing nonlexical information, but this was not true of slow young adults for whom the speed of processing lexical and nonlexical information was equivalent.
SNN: Stacked Neural Networks

It has been proven that transfer learning provides an easy way to achieve state-of-the-art accuracies on several vision tasks by training a simple classifier on top of features obtained from pre-trained neural networks. The goal of this work is to generate better features for transfer learning from multiple publicly available pre-trained neural networks. To this end, we propose a novel architecture called Stacked Neural Networks which leverages the fast training time of transfer learning while simultaneously being much more accurate. We show that using a stacked NN architecture can result in up to 8% improvements in accuracy over state-of-the-art techniques using only one pre-trained network for transfer learning. A second aim of this work is to make network fine- tuning retain the generalizability of the base network to unseen tasks. To this end, we propose a new technique called "joint fine-tuning" that is able to give accuracies comparable to finetuning the same network individually over two datasets. We also show that a jointly finetuned network generalizes better to unseen tasks when compared to a network finetuned over a single task.
Soluble group- and type-specific antigens from type III group B Streptococcus

Two soluble polysaccharide antigens of a type III group B Streptoccus were isolated from the culture medium after growth of strain M732 in a chemically defined broth supplemented with acid-hydrolyzed casein. The type- and group- specific antigens were isolated from the culture supernatant by anion-exchange chromatography with diethylaminoethyl-Sephacel. Two carbohydrate-containing peaks, which had serological reactivity with group B or type III antiserum, respectively, were eluted with a linear NaCl gradient and further purified by gel filtration. The type III polysaccharide was found to contain glucose, galactose, glucosamine, and sialic acid, whereas the group B polysaccharide contained galactose, glucosamine, and rhamnose. For the type III polysaccharide, sialic acid was shown to be the major immunodeterminant, and for the group B polysaccharide, rhamnose was the immunodominant sugar. Both the type III and group B polysaccharides were obtained in high yields without employing harsh physical or chemical treatment and both were immunologically distinct. By immunoelectrophoresis or counterimmunoelectrophoresis, type III antigen failed to react with group-specific antiserum and the group B antigen failed to react with type III antiserum.
Respiratory Symptoms and Cigarette Smoking in 3,197 Pulmonologist-Based Asthmatic Patients with a Highly Prevalent Use of Inhaled Corticosteroid

The relation between smoking and risk of asthma has been well-examined; however little attention has been paid to the correlation between smoking and asthma symptoms. The aims of this study were to examine respiratory symptoms in asthmatics with a highly prevalent use of inhaled corticosteroid (ICS) and to assess the effects of smoking and its cessation. A cross-sectional study of pulmonologist-based 3197 asthmatics (men 45.2%, ages 20–97) was performed using a questionnaire about smoking habits, the incidence and frequency of symptoms (sputum, cough and wheezing, night symptoms, and shortness of breath), physical activity interference, and medication. Although 81.4% of the patients used ICS according to the international guideline, 14.9% had activity interference, and daily symptoms remained in 43.3%. At the time of the questionnaire, 21.6% were current and 25.1% were ex-smokers. In multiple logistic regression analysis, the factors of significance (p<0.0001) were 1 smoking; for all four symptoms, 2 age and duration of asthma; for shortness of breath. Current smokers were at a risk of sputum (age-adjusted odds ratio 2.32 [95% confidence interval 1.73–3.11]; 2.09 [1.57–2.79]), of cough and wheezing (2.38 [1.81–3.14]; 1.78 [1.35–2.36]), of night symptoms (1.95 [1.41–2.60]; 1.47 [1.09–1.98]), and of shortness of breath (1.70 [1.26–2.28]; 1.30 [0.97–1.75]) in men and women, respectively. These ratios in ex-smokers decreased to the level similar to nonsmokers. Although 81.4% of asthmatic patients used ICS, 43.3% complained of daily respiratory symptoms, especially sputum. It is suggested that the effects of ICS on asthma symptoms may be interfered with by smoking and therefore more emphasis should be placed on cessation of smoking.
Performance driven face animation via non-rigid 3d tracking

In this demo, a performance driven 3D face animation system is proposed. The proposed system consists of two key components: a robust non-rigid 3D tracking module and a MPEG4 compliant facial animation module. Firstly, the facial motion is tracked from source videos which contain both the rigid 3D head motion (6 DOF) and the non-rigid expression variations. Afterward, the tracked facial motion is parameterized via estimating a set of MPEG4 facial animation parameters(FAP). As the final step, these FAP values are transferred to the MPEG4-compliant face model for the animation purpose. The proposed tracking and animation system has a strong generalization ability and can be used in the indoor environment with no additional assumptions.
Making Meaning of Life Events: Theory, Evidence, and Research Directions for an Alternative Model

Utilizing cognition, emotion, and psychotherapy research, theoretical and empirical evidence on adjustment to negative life events is reviewed. Two models of adjustment to negative life events are developed: the return-to-baseline model and the meaning-making model. The return-to-baseline model utilizes time and the return to a pre-event level of negativity, while the meaning-making model uses cognitive restructuring, increasing positive emotion, increasing regulation of negative emotion, and decreasing autonomic arousal. Meaning-making is a bridge from the negative emotion caused by negative life events to positive emotion through cognitive restructuring. Throughout the article new directions in adjustment research are suggested and the implicit uses of the return-to-baseline model in current research are uncovered.
Parallelising the k-Medoids Clustering Problem Using Space-Partitioning

The k-medoids problem is a combinatorial optimisation problem with multiples applications in Resource Allocation, Mobile Computing, Sensor Networks and Telecommunications.Real instances of this problem involve hundreds of thousands of points and thousands of medoids.Despite the proliferation of parallel architectures, this problem has been mostly tackled using sequential approaches.In this paper, we study the impact of space-partitioning techniques on the performance of parallel local search algorithms to tackle the k-medoids clustering problem, and compare these results with the ones obtained using sampling.Our experiments suggest that approaches relying on partitioning scale more while preserving the quality of the solution.
