Emotional intelligence competencies in the team and team leader: A multi‐level examination of the impact of emotional intelligence on team performance

Purpose – The purpose of this research is to examine the relationships among team leader emotional intelligence competencies, team level emotional intelligence, and team performance.Design/methodology/approach – It is argued here that the team leader's emotional intelligence (EI) will influence the development of group level emotional intelligence (GEI), which was measured by a team's emotionally competent group norms (ECGN). Second, it is hypothesized that the presence of ECGNs will positively influence group effectiveness. Data were collected from 422 respondents representing 81 teams in a military organization.Findings – Results show that team leader emotional intelligence is significantly related to the presence of emotionally competent group norms on the teams they lead, and that emotionally competent group norms are related to team performance.Research limitations/implications – Limitations of this research include a narrow sample with the teams not being highly interdependent.Practical implications.
Early Cosmological H II/He III Regions and Their Impact on Second-Generation Star Formation

We present the results of three-dimensional radiation hydrodynamics simulations of the formation and evolution of early H II/He III regions around the first stars. Cooling and recollapse of the gas in the relic H II region is also followed in a full cosmological context, until second-generation stars are formed. We first carry out ray-tracing simulations of ionizing radiation transfer from the first star. Hydrodynamics is directly coupled with photoionization heating as well as radiative and chemical cooling. The photoionized hot gas is evacuated out of the host halo at a velocity of ~30 km s-1. This radiative feedback effect quenches further star formation within the halo for over tens to a hundred million years. We show that the thermal and chemical evolution of the photoionized gas in the relic H II region is remarkably different from that of a neutral primordial gas. Efficient molecular hydrogen production in the recombining gas enables it to cool to ~100 K, where fractionation of HD/H2 occurs. The gas further cools by HD line cooling down to a few tens of kelvins. Interestingly, at high redshifts (z > 10), the minimum gas temperature is limited by that of the cosmic microwave background with TCMB = 2.728(1 + z). The gas cloud experiences runaway collapse when its mass is ~40 M☉, which is significantly smaller than a typical clump mass of ~200-300 M☉ for early primordial gas clouds. We argue that massive, rather than very massive, primordial stars may form in the relic H II region. Such stars might be responsible for early metal enrichment of the interstellar medium from which recently discovered hyper-metal-poor stars were born.
An interference alignment algorithm for structured channels

In this paper we propose a new interference alignment (IA) algorithm specifically designed to work with structured channels (e.g., diagonal or block-diagonal). Multiple-input multiple-output (MIMO) structured channels arise when symbol extensions - either in time or frequency - are employed jointly with the spatial dimension in the design of the precoders. In this case, the rank constraint in the direct channels must explicitly be taken into account into the optimization problem to ensure that there is no degrees-of-freedom (DoF) loss. To this end, we propose an algorithm that minimizes the interference leakage while ensuring that the direct links are full rank and the transmitters satisfy a power constraint. The algorithm is based upon an alternating optimization procedure, which solves a generalized eigenvalue problem at each step. We show through simulations the advantages of the proposed algorithm in several scenarios that use symbols extensions or improper (a.k.a. asymmetric) signalling.
Faster Choice-Reaction Times to Positive than to Negative Facial Expressions: The Role of Cognitive

Abstract Several studies have shown faster choice-reaction times to positive than to negative facial expressions. The present study examined whether this effect is exclusively due to faster cognitive processing of positive stimuli (i.e., processes leading up to, and including, response selection), or whether it also involves faster motor execution of the selected response. In two experiments, response selection (onset of the lateralized readiness potential, LRP) and response execution (LRP onset-response onset) times for positive (happy) and negative (disgusted/angry) faces were examined. Shorter response selection times for positive than for negative faces were found in both experiments but there was no difference in response execution times. Together, these results suggest that the happy-face advantage occurs primarily at premotoric processing stages. Implications that the happy-face advantage may reflect an interaction between emotional and cognitive factors are discussed.
Modality, Infinitives, and Finite Bare Verbs in Dutch and English Child Language

This article focuses on the meaning of nonfinite clauses (“root infinitives”) in Dutch and English child language. I present experimental and naturalistic data confirming the claim that Dutch root infinitives are more often modal than English root infinitives. This cross-linguistic difference is significantly smaller than previously assumed, however. Explaining the observations, I assume that morphology operates separately from syntax and semantics (Beard (1982; 1995)) and rely on the notion of underspecification (Halle and Marantz (1993), Harley and Noyer (1999)). It is argued that the Dutch infinitival verb and the English bare verb are both underspecified vocabulary items that can be inserted in various syntactic contexts. Syntactic differences between Dutch and English result in the inclusion of tensed root infinitives in English, whereas Dutch root infinitives are limited to untensed clauses. This proposal accounts for cross-linguistic differences in the meaning of root infinitives, cross-linguistic differences in type of the verbal predicate, variability in the meaning of root infinitives, and patterns in subject selection.
Formal and Informal Rural Credit in Four Provinces of Vietnam

Abstract This paper uses a survey of 932 rural households to uncover how the rural credit market operates in Vietnam. Households obtain credit through formal and informal lenders. Formal loans are almost entirely for production and asset accumulation, while informal loans are used for consumption smoothening. The determinants of formal and informal credit demand are distinct. While credit rationing depends on education and credit history, in particular, regional differences in the demand for credit are striking. A ‘one size fits all’ approach to credit policy in Vietnam would be inappropriate.
Identification of the Immediate-Early Transcripts of Kaposi’s Sarcoma-Associated Herpesvirus

ABSTRACT In the immediate-early phase of reactivation or primary infection, herpesviruses express a small number of genes without requiring prior viral protein synthesis. Immediate-early genes usually encode regulatory proteins critical for the viral life cycle. Kaposi’s sarcoma-associated herpesvirus (KSHV) gene transcription in the immediate-early stage of viral reactivation was examined by using a chemical induction combined with a gene expression screening method. RNA transcripts from at least four KSHV genomic loci accumulate when latently infected B-lymphoma cells are induced for reactivation in the presence of an inhibitor of protein synthesis (cycloheximide) and thus represent immediate-early class transcripts. Among them, a 3.6-kb mRNA encodes three putative open reading frames (ORFs), namely, ORF50, K8, and K8.2. ORF50 is a homologue of Rta, a transcription activator encoded by Epstein-Barr virus (EBV). The K8 gene codes for a 237-amino-acid protein with a basic-leucine zipper domain near its C terminus and an acidic domain near its N terminus and which closely resembles the ZEBRA protein of EBV and Jun/Fos family proteins. Other immediate-early mRNAs of KSHV include a 1.7-kb mRNA encoding ORF45, a 2.0-kb mRNA encoding ORF K4.2, and a 4.5-kb mRNA. Functional roles of products of these KSHV immediate-early transcripts remain to be studied.
Immune activation and depression in women with rheumatoid arthritis.

OBJECTIVE We examined markers of immune activation during periods of stress and depressive symptoms in 45 female patients with rheumatoid arthritis (RA) in comparison to 106 controls with no autoimmune disease. METHODS Depressive symptoms were recorded, clinician ratings of disease activity were made, and blood was drawn for RA patients and controls at baseline and during a designated stressful week. RESULTS Counts of T cell subpopulations revealed significant differences between RA and control groups in proportions of CD8 and CD4 cells, with higher CD4 and lower CD8 counts for the RA participants. Significant depression by diagnosis interactions were found, revealing greater CD4 activation among RA patients who were depressed in comparison to other groups. Only marginally significant effects of stress were found on T cell counts. Interleukin 6 (IL-6) concentrations also differentiated groups, with the highest levels of IL-6 observed for depressed RA patients under stress. CONCLUSION These findings provide new evidence that psychosocial factors play a significant role in autoimmune processes that underlie RA.
Malignant change in trichilemmal cysts: a study of cell proliferation and DNA content

We have examined proliferative activity in a series of pilar and trichilemmal cysts using an antibody to proliferating cell nuclear antigen. In benign lesions proliferative activity was confined to the basal layers of the squamous epithelium. Lesions showing malignant change showed increased proliferative activity and were not confined to the basal layer. These findings were correlated with studies on DNA content using flow cytometry.
Multivitamin Use and Risk of Stroke Mortality: The Japan Collaborative Cohort Study

Background and Purpose— An effect of multivitamin supplement on stroke risk is uncertain. We aimed to examine the association between multivitamin use and risk of death from stroke and its subtypes. Methods— A total of 72 180 Japanese men and women free from cardiovascular diseases and cancers at baseline in 1988 to 1990 were followed up until December 31, 2009. Lifestyles including multivitamin use were collected using self-administered questionnaires. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) of total stroke and its subtypes in relation to multivitamin use. Results— During a median follow-up of 19.1 years, we identified 2087 deaths from stroke, including 1148 ischemic strokes and 877 hemorrhagic strokes. After adjustment for potential confounders, multivitamin use was associated with lower but borderline significant risk of death from total stroke (HR, 0.87; 95% confidence interval, 0.76–1.01), primarily ischemic stroke (HR, 0.80; 95% confidence interval, 0.63–1.01), but not hemorrhagic stroke (HR, 0.96; 95% confidence interval, 0.78–1.18). In a subgroup analysis, there was a significant association between multivitamin use and lower risk of mortality from total stroke among people with fruit and vegetable intake <3 times/d (HR, 0.80; 95% confidence interval, 0.65–0.98). That association seemed to be more evident among regular users than casual users. Similar results were found for ischemic stroke. Conclusions— Multivitamin use, particularly frequent use, was associated with reduced risk of total and ischemic stroke mortality among Japanese people with lower intake of fruits and vegetables.
Multiregion Segmentation Based on Compact Shape Prior

To solve the problem of generating segmentations of meaningful parts from scanned models with freeform surfaces, we explore a compact shape prior-based segmentation approach in this paper. Our approach is inspired by an observation that a variety of natural objects consist of meaningful components in the form of compact shape and these components with compact shape are usually separated with each other by salient features. The segmentation for multiregions is performed in two phases in our framework. First, the segmentation is taken in low-level with the help of discrete Morse complex enhanced by anisotropic filtering. Second, we extract components with compact shape by using agglomerative clustering to optimize the normalized cut metric, in which the affinities of boundary compatibility, 2D shape compactness and 3D shape compactness are incorporated. The practical functionality of our approach is proved by applying it to the application of customized dental treatment. Note to Practitioners-The research work presented in this paper is to support the procedure of customized design and manufacturing. As a very important preprocessing step for the industrial design of many applications, the 3D shape of real objects must be scanned and reconstructed in computer systems. To assign semantic information to the reconstructed mesh surface, the surface are segmented into meaningful components which, however, is not a well-defined problem. There is no general segmentation approach that has good performance for scanned models with freeform surfaces. According to the observation that models in many industrial applications (e.g., customized dental treatment) have meaningful components in the form of compact shape (e.g., teeth) separating from other regions (e.g., gum), a segmentation method is developed in this paper by using the compact shape prior. The techniques developed here can speedup the design and manufacturing of devices for customized dental treatment (e.g., orthodontic braces).
MetaPocket: a meta approach to improve protein ligand binding site prediction.

The identification of ligand-binding sites is often the starting point for protein function annotation and structure-based drug design. Many computational methods for the prediction of ligand-binding sites have been developed in recent decades. Here we present a consensus method metaPocket, in which the predicted sites from four methods: LIGSITE(cs), PASS, Q-SiteFinder, and SURFNET are combined together to improve the prediction success rate. All these methods are evaluated on two datasets of 48 unbound/bound structures and 210 bound structures. The comparison results show that metaPocket improves the success rate from approximately 70 to 75% at the top 1 prediction. MetaPocket is available at http://metapocket.eml. org .
Peters ’ Comment on “ Streamflow input to Lake Athabasca , Canada ” by Rasouli et al . ( 2013 )

This paper provides a reply to a comment from Peters (2014) on our recent effort focused on evaluating changes in streamflow input to Lake Athabasca, Canada. Lake Athabasca experienced a 21.2 % decline in streamflow input between 1960 and 2010 that has led to a marked decline in its water levels in recent decades. A reassessment of trends in naturalized Lake Athabasca water levels shows insignificant changes from our previous findings reported in Rasouli et al. (2013), and hence our previous conclusions remain unchanged. The reply closes with recommendations for future research to minimize uncertainties in historical assessments of trends in Lake Athabasca water levels and to better project its future water levels driven by climate change and anthropogenic activities in the Athabasca Lake basin.
Pacific Asia Conference on Information Systems ( PACIS ) 2014 UNDERSTANDING THE COST ASSOCIATED WITH DATA SECURITY BREACHES

To estimate the cost of a data breach to the inflicted firm, this study examines the relationship between a breach incident and changes in the inflicted firm’s profitability, perceived risk, and the inflicted firms’ information environment transparency. Profitability is measured as reported earnings and analysts’ earnings forecasts. Perceived risk is measured as reported stock return volatility and dispersion among analysts’ forecasts. Although a number of studies have investigated the stock market reaction surrounding the disclosure of a breach incident to quantify the cost associated with breaches, we argue that there exists information uncertainty and deficiency in the disclosure of the breach incident and stock market reaction surrounding a security breach announcement date may not be the best measure for the cost of security breaches. And research using other complementary measures is warranted. Our preliminary finding suggests that data breaches negatively impact firm profitability, perceived risk and information transparency. Nevertheless, the damage of a breach most likely stems from direct costs such as compensation and litigation costs rather than indirect costs such as tarnished reputation and a decrease in market share and sales. More sophisticated analysts are also found to add value in estimating the real cost of a security breach.
Internal Thoracic Impedance - A Useful Method for Expedient Detection and Convenient Monitoring of Pleural Effusion

Measurement of internal thoracic impedance (ITI) is sensitive and accurate in detecting acute pulmonary edema even at its preclinical stage. We evaluated the suitability of the highly sensitive and noninvasive RS-207 monitor for detecting pleural effusion and for demonstrating increased ITI during its resolution. This prospective controlled study was performed in a single department of internal medicine of a university-affiliated hospital between 2012-2013. One-hundred patients aged 25–96 years were included, of whom 50 had bilateral or right pleural effusion of any etiology (study group) and 50 had no pleural effusion (controls). ITI, the main component of which is lung impedance, was continuously measured by the RS-207 monitor. The predictive value of ITI monitoring was determined by 8 measurements taken every 8 hours. Pleural effusion was diagnosed according to well-accepted clinical and roentgenological criteria. During treatment, the ITI of the study group increased from 32.9±4.2 ohm to 42.8±3.8 ohm (p<0.0001) compared to non-significant changes in the control group (59.6±6.6 ohm, p = 0.24). Prominent changes were observed in the respiratory rate of the study group: there was a decrease from 31.2±4.0 to 19.5±2.4 ohm (35.2%) compared to no change for the controls, and a mean increase from 83.6±5.3%-92.5±1.6% (13.2%) in O2 saturation compared to 94.2±1.7% for the controls. Determination of ITI for the detection and monitoring of treatment of patients with pleural effusion enables earlier diagnosis and more effective therapy, and can prevent hospitalization and serious complications, such as respiratory distress, and the need for mechanical ventilation. Trial Registration The study is registered at ClinicalTrials.gov NCT01601444
An Autocalibrated All-Digital Temperature Sensor for On-Chip Thermal Monitoring

This brief presents an autocalibrated all-digital temperature sensor circuit for use with on-chip thermal sensing applications. The proposed temperature sensor eliminates the need for two-temperature-point calibration in prior temperature sensors. Therefore, temperature sensor calibration efforts in high-volume production can be significantly reduced. The proposed design uses reference clock period information to perform self-calibration, and thus, effects of process variation can be removed. Subsequently, the accuracy of the proposed temperature sensor can be improved with very small area cost and low power consumption. The temperature sensor is implemented with a standard performance 65-nm complementary metal-oxide-semiconductor technology. The core area is 0.01 mm2, and the power consumption of the proposed circuit is 150 μW with a 1-V supply. Since the proposed temperature sensor can be easily calibrated with a reference clock, the proposed design is very suitable for dynamic thermal management applications in a system-on-a-chip era.
Pleasure-Related Analgesia Activates Opioid-Insensitive Circuits

Recent findings suggest that pain and pleasure share common neurochemical circuits, and studies in animals and humans show that opioid-mediated descending pathways can inhibit or facilitate pain. We explored the role of endogenous opioid neurotransmission in pleasure-related analgesia. μ-Opioidergic activity was blocked with 0.2 mg/kg naloxone to assess its effects on hedonic responses to pleasant emotional pictures (International Affective Picture System) and its modulating effects on heat pain tolerance. Naloxone did not alter subjective and autonomous reactions to pleasure induction or overall mood of participants. In addition, pleasure-related increases in pain tolerance persisted after reversal of endogenous μ-opioidergic neurotransmission. Subjective pain intensity and unpleasantness ratings increased after naloxone administration. These findings suggest that, in addition to opioid-sensitive circuits, mainly opioid-insensitive pain-modulating circuits are activated during pleasure-related analgesia.
On the sensitivity of radiative forcing from biomass burning aerosols and ozone to emission location

Biomass burning is a major source of air pollutants, some of which are also climate forcing agents. We investigate the sensitivity of direct radiative forcing due to tropospheric ozone and aerosols (carbonaceous and sulfate) to a marginal reduction in their (or their precursor) emissions from major biomass burning regions. We find that the largest negative global forcing is for 10% emission reductions in tropical regions, including Africa (−4.1 mWm−2 from gas and −4.1 mWm−2 from aerosols), and South America (−3.0 mWm−2 from gas and −2.8 mWm−2 from aerosols). We estimate that a unit reduction in the amount of biomass burned in India produces the largest negative ozone and aerosol forcing. Our analysis indicates that reducing biomass burning emissions causes negative global radiative forcing due to ozone and aerosols; however, regional differences need to be considered when evaluating controls on biomass burning to mitigate global climate change.
Perfect 1-Factorisations of Circulants with Small Degree

A $1$-factorisation of a graph $G$ is a decomposition of $G$ into edge-disjoint $1$-factors (perfect matchings), and a perfect $1$-factorisation is a $1$-factorisation in which the union of any two of the $1$-factors is a Hamilton cycle. We consider the problem of the existence of perfect $1$-factorisations of even order circulant graphs with small degree. In particular, we characterise the $3$-regular circulant graphs that admit a perfect $1$-factorisation and we solve the existence problem for a large family of $4$-regular circulants. Results of computer searches for perfect $1$-factorisations of $4$-regular circulant graphs of orders up to $30$ are provided and some problems are posed.
Increased Metastatic Dissemination in Human Melanoma Xenografts after Subcurative Radiation Treatment

Cancer patients showing local failure after radiation treatment have increased probability for developing metastatic disease. The mechanisms behind this observation have not been identified. In the present work, metastatic spread after inadequate radiation therapy was studied by using R-18 human melanoma xenografts as models of cancer in humans. Pimonidazole was used as a hypoxia marker, and hypoxia and urokinase-type plasminogen activator receptor (uPAR) expression were detected by immunohistochemistry. R-18 tumors regrowing after subcurative irradiation showed a higher frequency of lymph node metastasis than unirradiated tumors. The expression of uPAR was up-regulated in hypoxic tumor regions, and the fractions of hypoxic and uPAR-positive cells were ∼2-fold higher in regrowing irradiated tumors than in untreated tumors. Treatment with anti-uPAR antibody blocked metastasis almost completely in irradiated as well as unirradiated tumors. The metastatic frequency was higher in tumors regrowing after irradiation than in unirradiated tumors because the irradiation induced tumor hypoxia, and tumor hypoxia induced up-regulation of uPAR.
