Voice More and Stay Longer: How Ethical Leaders Influence Employee Voice and Exit Intentions

ABSTRACT: Given the importance of voice in ethical leadership theory, we analyze the relationship of ethical leadership to employee voice and the relationship of voice to exit intentions. Building on the theory of work engagement, we further hypothesize that cognitive engagement mediates these proposed relationships. To test these propositions, we conduct a field study to relate ethical leadership of supervisors, measured at time 1, to employees’ cognitive job engagement, measured at time 2. The analyses show that the relationship between these variables can account for supervisory ethical leadership’s association with employee voice and exit intentions. In a supplementary study using a different sample, we find that supervisory ethical leadership is related to exit intentions through voice. We discuss how these findings contribute to the literature on ethical leadership, employee voice, and exit.
Replication of a Continuing Education Workshop in the Evidence-Based Practice Process

Objective: To replicate the results of Parrish and Rubin’s continuing education workshop in the evidence-based practice (EBP) process utilizing different workshop facilitators with participants in a different geographic location. Methods: We used a replicated, one-group pretest–posttest design with 3-month follow-up to evaluate the effectiveness of a 7-hr, continuing education workshop. Social workers’ (N = 45) knowledge of, attitudes toward, views of feasibility, intentions to use, and current use of the EBP process were assessed. Results: Three of four cohorts of participants showed significant improvement from pretest to posttest in the overall measure of the EBP process (p < .05). Participants’ scores significantly improved over time regarding their familiarity with, attitudes about, and intentions to use and current use of the EBP process (p < .001). Conclusions: Parrish and Rubin’s continuing education workshop in the EBP process appears to be an effective means to train social workers in the EBP process.
E-business Capability Research: A Systematic Literature Review

In order to develop an extensive E-business Capability (EBC) model for better examining how e-business technology creates business value, this paper draws on the resource-based view of the firm, the IT process-oriented perspective, the net-enabled business innovation theory, and complementarity of resource, to review previous literature on EBC research and design an extensive framework. The research findings show further research should pursue an effective balance among technological, organizational, environmental and people factors contributing to e-business success. Our extensive EBC model suggests that an organization should not only pay attention to the initial capital investment, but also deeply analyze and study the value-generated process and related critical success factors, and effectively invest and manage these intermediate value-generated activities. This study provides a useful and comprehensive review on EBC research based on process-oriented perspective, better comparing and integrating previous literature on EBC research, and provides guidance to more efficiently and effectively uses e-business to significantly improve performance.
Epstein-Barr Virus EBER Transcripts Affect miRNA-Mediated Regulation of Specific Targets and Are Processed to Small RNA Species

The oncogenic Epstein-Barr virus (EBV) expresses 44 mature microRNAs and two non-coding EBER RNAs of 167 (EBER1) and 172 (EBER2) nt length. MiRNA profiling of NK/T cell lines and primary cells and Northern blotting of EBV-infected cell lines and primary tumors revealed processing of EBER1 to short 5′-derived RNAs of approximately 23, 52 and 70 nt (EBER123, EBER152, and EBER170) and of EBER2 to 3′ fragments. The biogenesis of these species is independent of Dicer, and EBER123 does not act like a miRNA to target its complementary sequence. EBER1, EBER2 and EBER123 were bound by the lupus antigen (La), a nuclear and cytoplasmic protein that facilitates RNAi. Consistent with this, the EBERs affect regulation of interleukin 1alpha (IL1α) and RAC1 reporters harboring miR target sequences, targets of miR-142-3p. However, the EBERs have no effect upon another target of miR-142-3p, ADCY9, nor on TOMM22, a target of ebv-miR-BART16, indicative of selective modulation of gene expression by the EBERs.
Internet Dependence in Chinese High School Students: Relationship with Sex, Self-Esteem, and Social Support

This cross-sectional study investigated the relationships among self-esteem, social support, and Internet dependence. A sample of young people aged between 15 and 18 years old (M age = 16.3yr., SD =0.7; 470 boys, 441 girls) completed measures of the Rosenberg Self-Esteem Scale, the Perceived Social Support Scale, and the Internet Dependence Test. According to the cognitive-behavioral model of problematic Internet use, social support should mediate the relationship between self-esteem and Internet dependence. Furthermore, based on previous research it was predicted that boys would score higher on Internet dependence than women. Support for this model was obtained. Internet dependent students were more likely to be boys. Self-esteem and social support were negatively correlated with Internet dependence. The relationship between self-esteem and Internet dependence was mediated by social support. Although the effect sizes were small, the findings of the present study are of significance in investigating adolescents' Internet dependence.

Skin temperature measured by infrared thermography after specific ultrasound-guided blocking of the musculocutaneous, radial, ulnar, and median nerves in the upper extremity.

BACKGROUND Sympathetic block causes vasodilatation and increases in skin temperature (T(s)). However, the T(s) response after specific nerve blocking is unknown. In this study, we hypothesized that T(s) would increase after specific blocking of the nerve innervating that area. METHODS Forty-six patients undergoing hand surgery were included. We performed ultrasound-guided, specific nerve blocking of either the musculocutaneous, radial, ulnar, or median nerve in each patient and analysed T(s) in the forearm and hand at 2 min intervals in the following 22 min by the use of infrared thermography. Areas of interest corresponding to the cutaneous innervation area of each of the four nerves were defined and the mean T(s) in each area was analysed. RESULTS Specific blocking of the ulnar and median nerves caused a substantial increase in mean (sd) T(s) in the areas innervated by these nerves [5.2 (3.2)°C and 5.1 (2.5)°C, respectively; both P<0.0001]. The increase was even larger at the fingertips. Median nerve blocking also increased T(s) in the area of the hand innervated by the radial nerve (P<0.0001). However, T(s) did not increase in any area after either musculocutaneous or radial nerve blocking. CONCLUSIONS Specific blocking of the ulnar and median nerve causes substantial increases in T(s) in specific areas of the hand. In contrast, the specific blocking of the musculocutaneous or radial nerve does not increase T(s). Further studies are needed to clarify if these findings can be used to objectively evaluate brachial plexus block success.
Analysis and Improvement of fairness among many TCP connections sharing Tail-Drop and RED Routers

The electrode structure, embedded in a refractory lining (1) covering the wall (2) of a vessel containing the bath (5) of metal, flush at one (4) of its ends with the inner surface of the refractory lining and projecting at its other end (6) out of the vessel, is of the type comprising an electrically conductive central core (3) extending through the wall (3) of the vessel and a cooling jacket (11) disposed around the central core (3) and in close contact therewith. The feature of the electrode structure is that the central core (3) is connected by its end (6) outside the vessel to an electric supply terminal (7), the zone of the central core (3) adjacent to the outer end (6) and in facing relation to the cooling jacket (11) being electrically insulated from the cooling jacket.
Tobacco Taxes and Smoking Bans Impact Differently on Obesity and Eating Habits

Policy interventions aimed at affecting a specific behavior may also indirectly affect individual choices in other domains. In this paper we study the direct effect of tobacco excise taxes and smoking bans on smoking behavior, and the indirect effect on eating behavior and body weight. Using very detailed clinical data on individual health, smoking, and dietary habits, we show that antismoking policies are effective in reducing smoking, but their consequences on eating behavior dramatically depend on the specific implemented policy. Increasing excise taxes on tobacco decreases body weight and caloric intake, and it improves the quality of eaten food. Smoking bans, instead, do not significantly affect body weight, although they impact on the diet composition. Smoking bans in restaurants induce a significant rise in the quality of food and in daily caloric intake. Conversely, smoking bans in bars negatively affect the quality of the daily diet, as individuals eat more fats and less fibers, and drink more alcohol and caffeine.
Silencing the self and personality vulnerabilities associated with depression.

In this chapter, we examine how personality factors associated with depression relate with self-silencing, a contextual perspective that focuses on interpersonal factors, with the following two main goals. First, we present the argument that there are many reasons why people engage in self-silencing, and these reasons reflect personality vulnerability factors associated with depression that also happen to be associated with self-silencing. While Jack (1991, 1999a) argues that a person self-silences to maintain existing interpersonal relationships, we contend that self-silencing can be motivated by many goals and objectives. Second, we outline our current work on self-silencing and personality vulnerability factors associatedwith depression.We argue that self-silencing is not only associated with a tendency to be depressed but also with some core personality traits associated with depressive vulnerability. Moreover, we argue that selfsilencing combines with these personality factors, either as a mediating or a moderating factor, to increase the risk for elevated levels of psychological distress. The three main personality factors we will focus on are dependency, selfcriticism, and perfectionism. The main motive for self-silencing among people with high levels of dependency and neediness is the desire to maintain relationships. However, self-evaluative concerns also play a significant role and contribute to self-silencing tendencies. People with high levels of self-criticism may silence the self because they are self-punitive and feel a sense of shame about aspects of their character and behavior. Similarly, perfectionistic people may self-silence because they are fearful of making mistakes and of the consequences of making mistakes. They may also engage in self-silencing because they are overly invested in publicly presenting an image of perfection.
Modelling Hurricane Exposure and Wind Speed on a Mesoclimate Scale: A Case Study from Cusuco NP, Honduras

High energy weather events are often expected to play a substantial role in biotic community dynamics and large scale diversity patterns but their contribution is hard to prove. Currently, observations are limited to the documentation of accidental records after the passing of such events. A more comprehensive approach is synthesising weather events in a location over a long time period, ideally at a high spatial resolution and on a large geographic scale. We provide a detailed overview on how to generate hurricane exposure data at a meso-climate level for a specific region. As a case study we modelled landscape hurricane exposure in Cusuco National Park (CNP), Honduras with a resolution of 50 m×50 m patches. We calculated actual hurricane exposure vulnerability site scores (EVVS) through the combination of a wind pressure model, an exposure model that can incorporate simple wind dynamics within a 3-dimensional landscape and the integration of historical hurricanes data. The EVSS was calculated as a weighted function of sites exposure, hurricane frequency and maximum wind velocity. Eleven hurricanes were found to have affected CNP between 1995 and 2010. The highest EVSS’s were predicted to be on South and South-East facing sites of the park. Ground validation demonstrated that the South-solution (i.e. the South wind inflow direction) explained most of the observed tree damage (90% of the observed tree damage in the field). Incorporating historical data to the model to calculate actual hurricane exposure values, instead of potential exposure values, increased the model fit by 50%.
Noninvasive assessment of myocardial stunning from short-term coronary occlusion using tagged magnetic resonance imaging.

Brief myocardial ischemia of less than 20 min duration, followed by reperfusion, is known to cause transient contractile dysfunction, often termed myocardial stunning. Tagged magnetic resonance imaging offers a noninvasive method that can be used to quantify this regional mechanical dysfunction in stunned myocardium. To this end, a closed-chest canine model of myocardial stunning was created by short-term (approximately 20-min) coronary occlusion, via inflation of an angioplasty balloon placed fluoroscopically in the left anterior descending (LAD) coronary, followed by reperfusion. Changes in myocardial strain before occlusion, during occlusion, and at 15 and 30 min after reperfusion were determined using repeated-measures analysis of variance. After instrumentation but before coronary occlusion, global reductions in myocardial strain were observed relative to animals that did not undergo coronary catheterization procedures. Declines of 46% and 49% in regional myocardial blood flow in the LAD and left circumflex bed, respectively, from preinstrumentation levels occurred due to coronary angiography and placement of a deflated angioplasty balloon in the LAD for 1 hr. During LAD occlusion, maximum myocardial shortening was significantly reduced in the anterior and anteroseptal regions of the left ventricular apex (i.e., ischemic region) but returned to baseline values by 30 min after reperfusion. No augmentation of myocardial function was observed in the nonischemic regions during occlusion or reperfusion. Thus, this noninvasive technique to evaluate myocardial ischemia demonstrated a graded response in myocardial function to ischemia and persistent regional dysfunction or "myocardial stunning" after short-term coronary occlusion.
A walk on the WILD side: how wireless handhelds may change CSCL

Designs for CSCL applications usually presume a desktop/laptop computer. Yet future classrooms are likely to be organized around Wireless Internet Learning Devices (WILD) that resemble graphing calculators or Palm handhelds, connected by short-range wireless networking. WILD learning will have physical affordances that are different from today's computer lab, and different from classrooms with 5 students per computer. These differing affordances may lead to learning activities that deviate significantly from today's images of K-12 CSCL activities. Drawing upon research across a range of recent handheld projects, we suggest application-level affordances around which WILD-based CSCL has begun to organize: (a) augmenting physical space, (b) leveraging topological space, (c) aggregating coherently across all students, (d) conducting the class, and (e) act becomes artifact. We speculate on how CSCL research may consequently evolve towards a focus on kinds of systemic coupling in an augmented activity space.
Developing media management scholarship: a commentary to Picard and Lowe’s essay

As eminences of the field of media management – which exists as a scholarly field not least thanks to their very efforts – in the essay “Questioning Media Management Research”, Robert G. Picard and Gregory F. Lowe (2016) provide their thoughts about the state of the field in a fun, yet provocative way. Making use of “parables”, they discuss four different, but interrelated areas for improvement of the field. All of these four areas are variations of the same theme – namely, the assessment that media management scholarship should improve in quality. As much as I agree with this assessment at large, I believe that there is a need to further elaborate on how we could actually go about to further develop media management as an academic field. Therefore, the aim with this commentary to Picard and Lowe’s essay is to critically discuss their analyses and provide some hands-on suggestions for what we, jointly, could do to develop media management scholarship. The findings derived from Picard and Lowe’s critical assessment of the media management field are not novel per se – similar results have been presented for example by Achtenhagen & Mierzejewska (2015), Krumsvik & Ots (2016), Küng (2007) and Ots, Nyilasy, Rohn, and Wikström (2015). However, this is positive, as only if such assessment is shared and voiced by many scholars, change might happen – and the novel approach chosen by Picard and Lowe to present their results in form of parables might certainly trigger attention and reflection. Picard and Lowe applaud that the media management field recently has seen an increase in number of different theories used, while criticising that these theories are merely applied to empirical phenomena, but neither expanded based on the empirical insights gained nor modified to fit the media management context. Interestingly, several of the theories mentioned have actually been (co-)developed by general management scholars drawing on empirical examples or studies from the media industries, but being published in general management, rather than media management, journals. For example, Coser, Kadushin and Powell (1982) studied the evolution of American college textbook publishing, tracking it through a period of initial diversity to the hegemony of only two models, the large bureaucratic generalist and the small specialist. Thereby, they advanced our understanding of an important question within institutional theory, namely, why many organisations in the same industry tend to be homogeneous. Similarly, Alvarez, Mazza, Strandgaard Pedersen, and Svejenova (2005) advanced
Transcriptomic Analysis of Rhizobium leguminosarum Biovar viciae in Symbiosis with Host Plants Pisum sativum and Vicia cracca

ABSTRACT Rhizobium leguminosarum bv. viciae forms nitrogen-fixing nodules on several legumes, including pea (Pisum sativum) and vetch (Vicia cracca), and has been widely used as a model to study nodule biochemistry. To understand the complex biochemical and developmental changes undergone by R. leguminosarum bv. viciae during bacteroid development, microarray experiments were first performed with cultured bacteria grown on a variety of carbon substrates (glucose, pyruvate, succinate, inositol, acetate, and acetoacetate) and then compared to bacteroids. Bacteroid metabolism is essentially that of dicarboxylate-grown cells (i.e., induction of dicarboxylate transport, gluconeogenesis and alanine synthesis, and repression of sugar utilization). The decarboxylating arm of the tricarboxylic acid cycle is highly induced, as is γ-aminobutyrate metabolism, particularly in bacteroids from early (7-day) nodules. To investigate bacteroid development, gene expression in bacteroids was analyzed at 7, 15, and 21 days postinoculation of peas. This revealed that bacterial rRNA isolated from pea, but not vetch, is extensively processed in mature bacteroids. In early development (7 days), there were large changes in the expression of regulators, exported and cell surface molecules, multidrug exporters, and heat and cold shock proteins. fix genes were induced early but continued to increase in mature bacteroids, while nif genes were induced strongly in older bacteroids. Mutation of 37 genes that were strongly upregulated in mature bacteroids revealed that none were essential for nitrogen fixation. However, screening of 3,072 mini-Tn5 mutants on peas revealed previously uncharacterized genes essential for nitrogen fixation. These encoded a potential magnesium transporter, an AAA domain protein, and proteins involved in cytochrome synthesis.
Completion of the Chloroplast Genomes of Five Chinese Juglans and Their Contribution to Chloroplast Phylogeny

Juglans L. (walnuts and butternuts) is an economically and ecologically important genus in the family Juglandaceae. All Juglans are important nut and timber trees. Juglans regia (Common walnut), J. sigillata (Iron walnut), J. cathayensis (Chinese walnut), J. hopeiensis (Ma walnut), and J. mandshurica (Manchurian walnut) are native to or naturalized in China. A strongly supported phylogeny of these five species is not available due to a lack of informative molecular markers. We compared complete chloroplast genomes and determined the phylogenetic relationships among the five Chinese Juglans using IIumina sequencing. The plastid genomes ranged from 159,714 to 160,367 bp encoding 128 functional genes, including 88 protein-coding genes and 40 tRNA genes each. A complete map of the variability across the genomes of the five Juglans species was produced that included single nucleotide variants, indels (insertions and deletions), and large structural variants, as well as differences in simple sequence repeats (SSR) and repeat sequences. Molecular phylogeny strongly supported division of the five walnut species into two previously recognized sections (Juglans/Dioscaryon and Cardiocaryon) with a 100% bootstrap (BS) value using the complete cp genomes, protein coding sequences (CDS), and the introns and spacers (IGS) data. The availability of these genomes will provide genetic information for identifying species and hybrids, taxonomy, phylogeny, and evolution in Juglans, and also provide insight into utilization of Juglans plants.
Learning Scalable Discriminative Dictionary with Sample Relatedness

Attributes are widely used as mid-level descriptors of object properties in object recognition and retrieval. Mostly, such attributes are manually pre-defined based on domain knowledge, and their number is fixed. However, pre-defined attributes may fail to adapt to the properties of the data at hand, may not necessarily be discriminative, and/or may not generalize well. In this work, we propose a dictionary learning framework that flexibly adapts to the complexity of the given data set and reliably discovers the inherent discriminative middle-level binary features in the data. We use sample relatedness information to improve the generalization of the learned dictionary. We demonstrate that our framework is applicable to both object recognition and complex image retrieval tasks even with few training examples. Moreover, the learned dictionary also help classify novel object categories. Experimental results on the Animals with Attributes, ILSVRC2010 and PASCAL VOC2007 datasets indicate that using relatedness information leads to significant performance gains over established baselines.
