Does authentic leadership predict employee work engagement and in-role performance? Considering the role of learning goal orientation

Abstract. This study sought to examine whether and why authentic leadership predicts followers’ in-role performance and did so in a four-wave, multi-level, multi-source field study conducted in the banking sector in Pakistan. Working from the notion that authentic leadership fosters followers’ focus on developing their true self; we suggest authentic leadership predicts followers’ learning goal orientation. Given that learning goal orientation strongly impacts on how people approach and experience their work, in turn, we expected that learning goal orientation determines followers’ work engagement, and their in-role performance. Results indicated learning goal orientation mediated the relationship between authentic leadership and (a) follower performance and (b) work engagement.
A Comprehensive Mapping of HIV-1 Genotypes in Various Risk Groups and Regions across China Based on a Nationwide Molecular Epidemiologic Survey

Background China is experiencing a dynamic HIV/AIDS epidemic. While serology based surveillance systems have reported the spread of HIV/AIDS, detailed tracking of its transmission in populations and regions is not possible without mapping it at the molecular level. We therefore conducted a nationwide molecular epidemiology survey across the country. Methods HIV-1 genotypes were determined from 1,408 HIV-positive persons newly diagnosed in 2006. The prevalence of each genotype was estimated by weighting the genotype’s prevalence from each province- and risk-specific subpopulation with the number of reported cases in the corresponding subgroups in that year. Results CRF07_BC (35.5%), CRF01_AE (27.6%), CRF08_BC (20.1%), and subtype B' (9.6%) were the four main HIV-1 strains in China. CRF07_BC and CRF08_BC were the primary drivers of infection among injecting drug users in northeastern and southeastern China, respectively, and subtype B' remained dominant among former plasma donors in central China. In contrast, all four strains occurred in significant proportions among heterosexuals nationwide, pointing to an expansion of the HIV-1 epidemic from high-risk populations into the general population. CRF01_AE also replaced subtype B as the principal driver of infection among men-who-have-sex-with-men. Conclusions Our study provides the first comprehensive baseline data on the diversity and characteristics of HIV/AIDS epidemic in China, reflecting unique region- and risk group-specific transmission dynamics. The results provide information critical for designing effective prevention measures against HIV transmission.
Neighbourhood characteristics and confidence in the police in the context of South Korea

ABSTRACT This study examines the generalisability of research on neighbourhood influences on confidence in the police to the context of South Korea. In addition, we propose and test a theoretical model in which neighbourhood context influences confidence in the police indirectly via collective efficacy. We estimate multilevel models using the 2008 Korean Crime Victimization Survey. Neighbourhood disorder, residential stability, and collective efficacy affected citizens’ confidence in the police. The effects of disorder and residential stability on perceptions of the police were mediated by collective efficacy. We confirmed that several factors that have been shown to influence confidence in the police in the West are also important predictors in South Korea. Police need to be more concerned about issues such as disorder, social cohesion, and moral consensus, because when these values and structures are under threat, residents are more likely to have lower levels of confidence in the police.
The dynamics of the spherical p-spin model: From microscopic to asymptotic

We have numerically investigated the mean-field dynamics of the the p-spin interaction spin glass model with p = 3 using an efficient method of integrating the dynamic equations. We find a new time scale associated with the onset of the breakdown of the fluctuation-dissipation theorem in the intermediate time regime. We also find that the off-equilibrium relaxation exhibits a sub-aging behavior in the intermediate times and crosses over to a simple aging in the asymptotic regime.
Outer bounds and a functional study of the edge removal problem

In this paper, we investigate the impact of a single edge on the capacity region of a network of error-free, point-to-point links. A family of networks and edges is said to exhibit the “edge removal property” if for any network and edge in the family, removing a δ-capacity edge changes the capacity region by at most δ in each dimension. We derive a sufficient condition on network coding functions to guarantee that the edge removal property holds when the network is operated using functions satisfying the condition. Also, we extend the family of network capacity bounds for which it is known that removing a single edge of capacity δ changes the capacity bound by at most f(δ) in each dimension. Specifically, we show that removing a single δ-capacity edge changes the Generalized Network Sharing outer bound by at most δ in each dimension and the Linear Programming outer bound by at most a constant times δ in each dimension.
Stationary Structures of Irrotational Binary Systems: Models for Close Binary Systems of Compact Stars

We propose a new numerical method to calculate irrotational binary systems composed of compressible gaseous stars in Newtonian gravity. Assuming irrotationality, i.e., vanishing of the vorticity vector everywhere in the star in the inertial frame, we can introduce the velocity potential for the flow field. Using this velocity potential we can derive a set of basic equations for stationary states that consist of (1) the generalized Bernoulli equation, (2) the Poisson equation for the Newtonian gravitational potential, and (3) the equation for the velocity potential with the Neumann-type boundary condition. We succeeded in developing a new code to compute numerically exact solutions to these equations for the first time. Such irrotational configurations of binary systems are appropriate models for realistic neutron star binaries composed of inviscid gases, just prior to coalescence of two stars caused by emission of gravitational waves. Accuracies of our numerical solutions are so high that we can compute reliable models for fully deformed final stationary configurations and hence determine the inner most stable circular orbit of binary neutron star systems under the approximations of weak gravity and inviscid limit.
Sex-Based Differences in Early Mortality of Patients Undergoing Primary Angioplasty for First Acute Myocardial Infarction

Background—Morbidity and mortality after an acute myocardial infarction (AMI) has been reported to be higher in women than men. However, in some prior reports, women were not treated as aggressively as men, suggesting a treatment bias. We sought to determine whether sex influenced short-term outcomes in a cohort of AMI patients, all of whom underwent primary angioplasty. Methods and Results—We conducted a retrospective cohort study of all patients undergoing primary angioplasty for a first AMI in New York State in 1995. A total of 1044 patients, 317 women and 727 men, were identified. Mean age was 59±12 years in men and 65±12 years in women (P <0.05). Women had a higher prevalence of hypertension (59% versus 44%, P <0.05), diabetes (19% versus 14%, P <0.05), and peripheral vascular or carotid disease (9.5% versus 5.5%, P <0.05) than men. Men were more likely to be treated earlier (within 6 hours) from the time of symptom onset than women (74% versus 63%, P <0.05). Women had a higher incidence of shock or hemodynamic instability than men (25% versus 17%, P <0.05). The unadjusted in-hospital mortality rate was 7.9% in women and 2.3% in men (P <0.05). After multivariate logistic regression analysis, women maintained a 2.3-fold higher risk of in-hospital death compared with their male counterparts (95% confidence interval [CI], 1.2 to 4.6, P =0.016). Conclusions—After correcting for age and baseline risk differences, women undergoing primary angioplasty for AMI have a significantly higher in-hospital mortality rate than men.
TweetCred: A Real-time Web-based System for Assessing Credibility of Content on Twitter

During large scale events, a large volume of content is posted on Twitter, but not all of this content is trustworthy. The presence of spam, advertisements, rumors and fake images reduces the value of information collected from Twitter, especially during sudden-onset crisis events where information from other sources is scarce. In this research work, we describe various facets of assessing the credibility of usergenerated content on Twitter during large scale events, and develop a novel real-time system to assess the credibility of tweets. Firstly, we develop a semi-supervised ranking model using SVM-rank for assessing credibility, based on training data obtained from six high-impact crisis events of 2013. An extensive set of forty-five features is used to determine the credibility score for each of the tweets. Secondly, we develop and deploy a system–TweetCred–in the form of a browser extension, a web application and an API at the link: http://twitdigest.iiitd. edu.in/TweetCred/. To the best of our knowledge, this is the first research work to develop a practical system for credibility on Twitter and evaluate it with real users. TweetCred was installed and used by 717 Twitter users within a span of three weeks. During this period, a credibility score was computed for more than 1.1 million unique tweets. Thirdly, we evaluated the real-time performance of TweetCred , observing that 84% of the credibility scores were displayed within 6 seconds. We report on the positive feedback that we received from the system’s users and the insights we gained into improving the system for future iterations.
Summating Potential in Meniere's Disease

Summating potential (SP) findings in Meniere's disease were reviewed based mainly on the results of our study. Many studies have confirmed that an increased negative SP is observed more often in ears with endolymphatic hydrops such as Meniere's disease than in ears with other diseases. Recent reports have showed that negative SP in Meniere's disease is unchanged during hearing fluctuation although action potential (AP) is changed, and that positive SP is more frequently observed in Meniere's disease. Our recent study suggests that positive SP may provide different information on the pathophysiology of Meniere's disease from that obtained from negative SP. Recent reports have demonstrated that the combination of electrocochleography with glycerol test increases the diagnostic rate of Meniere's disease.
Activity and Interaction of Students in an Electronic Learning Environment for Problem-Based Learning

This paper contains the results of an experimental study in which students used a collaborative learning tool in the time between regular meetings of a tutorial group in problem-based learning. The analysis of the learning situation for which this tool was developed, as well as the evaluation of the experiment, is based on a model of collaborative learning that covers three sections. The first is the learning environment that mediates the second section learning behaviour and the third section learning mechanisms . From the perspective of the stimulation of productivity in collaborative learning, the relation between characteristics of the problem task (learning environment) and interactions (learning behavior) was explored. In problem-based learning students formulate learning issues after a brainstorm discussion in the group. Students formulate theoretical and practical learning issues. Two research questions are presented in this study: What types of learning issues generate most interactions? and What types of learning issues generate the highest level of information processing? The first question is concerned with an analysis of the number of interactions and the second with the quality of these interactions. Practical learning issues generated more interactions, as well as a higher level of information processing. These results are discussed in the context of social factors in learning.
Influence of Patient Attachment Style on Self-care and Outcomes in Diabetes

Objective: Difficulties collaborating with providers and important others may adversely influence self-management in patients with diabetes. We predicted that dismissing attachment style, characterized by high interpersonal self-reliance and low trust of others, would be associated with poorer self-management in patients with diabetes. Methods: A population-based mail survey was sent to all patients with diabetes from nine primary care clinics of a health maintenance organization. We collected data on attachment style, self-care behaviors, the patient provider relationship and depression status and accessed automated diagnostic, pharmacy, and laboratory data to measure diabetes treatment intensity, medical comorbidity, glycosylated hemoglobin levels, and diabetes complications. We used logistic regression to determine whether dismissing attachment style was associated with poorer diabetes self-care behaviors, adherence to medication, smoking status, and higher glycosylated hemoglobin. Results: In 4095 primary care patients with diabetes, prevalence rates for secure, dismissing, preoccupied, and fearful attachment styles were 44.2%, 35.8%, 7.9%, and 12.1%, respectively. When compared with secure attachment style, dismissing attachment style was associated with significantly lower levels of exercise (p = .005), foot care (p < .05), diet (p = .001), and adherence to oral hypoglycemic medications (p < .05), and with higher rates of smoking (p < .05), and these associations were mediated through the patient-provider relationship. Preoccupied attachment style, characterized by overreliance on others, was associated with a significantly lower risk of having glycosylated hemoglobin levels >8%, compared with secure attachment style. Conclusion: Attachment style is significantly associated with diabetes self-management and outcomes. HbA1c = glycosylated hemoglobin; GHC = Group Health Cooperative; BMI = body mass index; IV = independent variable; DV = dependent variable.
Learning to buy a Renault and talk to BMW: A supervised approach to conventional metonymy

A method and apparatus are described for determining the occurrence or non-occurrence of subsurface air flow and, in the event of the occurrence of subsurface air flow, being able to determine its direction into or out of the earth. The determinations are accomplished by the use of a pair of alpha particle detectors, each of which is disposed in a protective enclosure to constitute a detector unit. A pair of such units is employed, the two units being buried in the earth spaced from each other and at different depths. Readings detecting alpha particle emission are taken on both units and compared.
Age and Menopausal Status Affect Osteoprotegerin and Osteocalcin Levels in Women Differently, Irrespective of Thyroid Function

Osteoprotegerin (OPG) and osteocalcin (OC) are essential bone proteins. Recent studies have demonstrated that they are not secreted solely by bone cells; they play roles in the vascular function and energy metabolism, and they are influenced by multiple factors. The aim of the current study was to investigate the influence of menopause and age on OPG and OC in women with different thyroid-stimulating hormone (TSH) levels. Material and Methods We studied 49 women with elevated TSH, 26 with suppressed TSH, and 67 age-matched euthyroid controls. Of them 64 were menstruating and 78 postmenopausal. Body weight, height, waist circumference (WC), body mass index (BMI), serum TSH, free thyroxin (FT4), OPG, and OC were measured. Results Generally, both OPG and OC were higher in the postmenopausal women than in the menstruating subjects (OPG 3.85 ± 1.49 pmol/L vs. 5.84 ± 2.42 pmol/L, P < 0.001; OC 8.84 ± 3.70 ng/dL vs. 12.87 ± 6.45 ng/dL, P < 0.001), and within the two thyroid dysfunction subgroups and the controls (all P < 0.05). OPG correlated with age (postmenopausal rho = 0.57, P < 0.001; premenopausal rho = 0.31, P = 0.015). Among the premenopausal subjects, OPG was higher in those with low TSH than in the controls (P = 0.048). OC correlated negatively with BMI and WC in the postmenopausal group (Spearman rho = –-0.25, P = 0.03 and rho = –-0.42, P < 0.001 respectively). OC was higher in the postmenopausal subjects with low TSH than in those with elevated TSH (P = 0.024), and correlated positively with FT4 (rho = 0.40, P = 0.002) and negatively with TSH (rho = -0.29, P = 0.013). CONCLUSIONS In women, OPG and OC depended differently on age and menopause and, to a lesser extent, on the thyroid function and body composition.
Dispersion in Analysts' Earnings Forecasts and Credit Rating

This paper shows that the puzzling negative cross-sectional relation between dispersion in analysts' earnings forecasts and future stock returns may be explained by financial distress, as proxied by credit rating downgrades. Focusing on a sample of firms rated by Standard & Poor's (S&P), we show that the profitability of dispersion-based trading strategies concentrates in a small number of the worst-rated firms and is significant only during periods of deteriorating credit conditions. In such periods, the negative dispersion-return relation emerges as low-rated firms experience substantial price drop along with considerable increase in forecast dispersion. Moreover, even for this small universe of worst-rated firms, the dispersion-return relation is non-existent when either the dispersion measure or return is adjusted by credit risk. The results are robust to previously proposed explanations for the dispersion effect such as short-sale constraints and leverage.
Climate Change Versus Global Warming: Who Is Susceptible to the Framing of Climate Change?

The terms global warming and climate change are often used interchangeably, but recent research finds “global warming” has become more emotive and more polarizing, resulting in less advocacy by some subpopulations. We explore the robustness of this framing effect based on the expectation that people with stronger partisan identities tend to have more deep-seated climate change beliefs. We use multiple methods and measures to study framing across a range of attitude scales designed to measure climate change beliefs, degree of knowledge about climate change, and intentions to take corrective actions. We find stronger framing effects for political Independents and those who are disengaged from climate change issues, indicating that polarization overrides framing at the extremes, and those with moderate beliefs are more susceptible to labeling and framing effects, especially when beliefs are inconsistent with one’s political identity. We conclude by urging communicators to appreciate the heterogeneity of their target audience.
Ternary combination of irinotecan, fluorouracil-folinic acid and oxaliplatin: results on human colon cancer cell lines

A marked antitumour efficacy is currently obtained by oxaliplatin (LOHP)–fluorouracil (FU)–folinic acid (FA) combination and by CPT11–FU–FA combination. Logically, the triple association LOHP, CPT11 and FUFA will be soon tested in cancer patients. The aim of the present study was to compare two schedules combining SN38 (the active metabolite of CPT11, irinotecan) with FU–FA and LOHP. The two schedules differed by the SN38 position. The relative contribution of each drug in the resulting global cytotoxicity was evaluated. Two human colon cancer cell lines were used (WIDR and SW620 both p53 mutated). LOHP plus FA were applied for 2 h, just before a 48 h FU exposure. The SN38 sequence was applied for 24 h, starting either 48 h before LOHP-FA (schedule A), or just after LOHP-FA exposure (schedule B). Cytotoxicity was assessed by the 3-(4,5-demethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) test and drug interactions were analysed according to the Chou and Talalay method, based on the computation of a combination index (CI). The SN38 position significantly induces a shift from additivity-antagonism when SN38 was applied after LOHP, towards additivity-synergism when SN38 was applied first (P = 0.03). The relative contribution (RC) of each drug in the overall cytotoxicity of the triple combination was defined as the drug concentration giving 50% cell lethality (IC50) of the double association without that drug divided by the IC50of the triple association. Whatever the SN38 position, the larger contribution was made by LOHP (median RC = 2.4) and the smaller by SN38 (median RC = 1.1). In addition, the contribution of FUFA was improved when SN38 was applied first (median RC = 2.2) as compared to the opposite schedule (median RC = 1.2). Results were in agreement between the two explored cell lines. The present data should be taken into account when establishing the rationale of future trials combining CPT11, LOHP and FU–FA. http://www.bjcancer. com © 2001 Cancer Research Campaign
Recognising diverse learning styles in teaching and assessment of electronic engineering

University of South Australia initiatives to make the electronic engineering curriculum more inclusive have been supported and informed by corporate policies. These policies require all curricula to be inclusive, and also to develop specified graduate attributes. After an overview of the literature about learning styles, this paper describes how the corporate advice is implemented in the electronic engineering curriculum. The authors have identified two different interpretations of the term 'learning styles'. The first interpretation sees personality and life experience as the key influences on learning styles, while the second defines learning styles as the practices students develop in response to the expectations of their teachers. The literature relating to each interpretation is considered, with particular reference to certain social and cultural groups which are under-represented in electronic engineering in the authors' university. Finally, the authors demonstrate the integration of these concepts and approaches into the learning and assessment strategies of an electronics course.
Reading Fluency for the iGeneration: A Longitudinal Analysis of the Impact of MP3 Use and Teacher Experience

Reading fluency has been identified as an essential skill in early readers. The technological boom to which students in the iGeneration have been exposed, has produced many potential tools for developing reading fluency. This study investigated reading fluency and technology. The design of the study presented here allowed the researchers to ask two questions related to the development of reading fluency in 2nd graders. First, did the use of MP3 players as an at-home tool increase reading fluency in 2nd graders? Second, did teacher experience increase the reading fluency of these 2nd graders? The results indicated that the use of MP3 players as an at-home tool did not have a statistically significant impact on reading fluency. However, teacher experience did have a statistically significant impact on reading fluency. Several explanations for these results are discussed including the, perhaps, outdated choice of the MP3 player as the technological tool utilized in the study. In addition, questions are raised about the efficacy of using the MP3 player as a homework-type of assignment. While the importance of establishing a solid home-school connection is noted, schools may need to rethink the most beneficial methods for building that connection with ALL parents/families. Teacher experience is, not surprisingly, connected to student achievement. This result highlighted the need for schools to develop an environment for beginning teachers to grow and find support. Keeping teachers in the classroom is of utmost importance to student achievement.
