Leadership Styles, Diversity in Work Groups, Work Group Effectiveness, and Turnover Intention

The emergence of our borderless world has resulted in the nationwide intermingling of people of differing demographics and social cultural backgrounds, working together for the common good of organizations. This evolving growth in workforce diversity has resulted in an ever-increasing appearance of diverse work groups in almost every industry because history has shown that "none of us is as smart as all of us" working together (Blanchard & Bowles, 2001, p.111). Many organizations and institutions, including Fortune 500 companies, are utilizing work groups for various types of tasks and projects. Motorola, for example, has approximately 4,000 work groups operating in its facilities around the globe, and research has shown organization-wide cost saving benefits (Cohen 8z Bailey, 1997). Collaborative performance and work group effectiveness are benefits of diverse work groups because the total group's contribution becomes more significant than individual efforts. Challenges in group dynamics, however, often require leadership to ensure the group's effectiveness and to guard against employees leaving their organizations. The literature is very explicit about the crucial role of leadership in ensuring that work groups are effective (Jung & Sosik, 2002; Waldman, Ramirez, House and Puranam, 2001 ; House, 1971; & Fielders, 1967). In spite of this, only a few researchers have focused on the concept of leadership style and its relationship to the collaborative efforts of work groups. (Duemer, L. S., et al., 2004).
The mediating role of identity incompatibility in the relationship between perceived discrimination and acculturation preferences in two generations of the ethnic Russian minority in the North Caucasus

Abstract The present study tested a model in which the perceived incompatibility of ethnic Russian and regional North Caucasian identities mediates the relationship between perceived discrimination and acculturation strategies in two generations of ethnic Russian minority members living in the Kabardino-Balkar Republic, North Caucasus, Russian Federation. Two identities might be perceived incompatible when they represent conflicting sets of norms and values and the two communities may place competing demands on individual commitment and loyalty. We sampled 105 dyads from ethnic Russian families (youth: M = 18 years, SD = 2.35, 48.6% female; parents: M = 43 years, SD = 6.97, 68.6% female). The questionnaire included measures of perceived discrimination, perceived identity incompatibility, and acculturation strategies. The results of multigroup path analysis showed that the perceived identity incompatibility mediated the relationship between perceived discrimination and two strategies, aimed at culture maintenance (integration and separation) in both generations. Identity incompatibility is regarded as a psychological mechanism that explains the impact of perceived discrimination on minority acculturation preferences in a multicultural region.
Transduction with Conndence and Credibility

In this paper we follow the same general ideology as in Gammerman et al., 1998], and describe a new transductive learning algorithm using Support Vector Machines. The algorithm presented provides conndence values for its predicted classiications of new examples. We also obtain a measure of \credibility" which serves as an indicator of the reliability of the data upon which we make our prediction. Experiments compare the new algorithm to a standard Support Vector Machine and other trans-ductive methods which use Support Vector Machines , such as Vapnik's margin transduction. Empirical results show that the new algorithm not only produces conndence and credibility measures, but is comparable to, and sometimes exceeds the performance of the other algorithms .

Recently, multimedia-based learning is widespread in educational settings. A number of studies investigate how to develop effective techniques to manage a huge volume of video sources, such as summarization and recommendation. However, few studies examine how these techniques affect learners' perceptions in multimedia learning systems. This article aims to examine learners' perceptions for summarization and recommendation, with an emphasis on the perspective of prior experience. In this study, we developed a multimedia content summarization and recommendation system, which can automatically extract summaries from raw video sources and recommend suitable video content to learners through emails. The results demonstrate that learners' prior experience and preferences for the presentation of document types affect their perceptions, including the enhancement of interests, the ease of information acquisition and the intention for the further use of the system. Finally, the findings are applied to develop a framework that can support for the design of multimedia learning systems.
An Orally Active Epoxide Hydrolase Inhibitor Lowers Blood Pressure and Provides Renal Protection in Salt-Sensitive Hypertension

The present study tested the hypothesis that increasing epoxyeicosatrienoic acids by inhibition of soluble epoxide hydrolase (sEH) would lower blood pressure and ameliorate renal damage in salt-sensitive hypertension. Rats were infused with angiotensin and fed a normal-salt diet or an 8% NaCl diet for 14 days. The sEH inhibitor, 12-(3-adamantan-1-yl-ureido)-dodecanoic acid (AUDA), was given orally to angiotensin-infused animals during the 14-day period. Plasma AUDA metabolite levels were measured, and they averaged 10±2 ng/mL in normal-salt angiotensin hypertension and 19±3 ng/mL in high-salt angiotensin hypertension on day 14 in the animals administered the sEH inhibitor. Mean arterial blood pressure averaged 161±4 mm Hg in normal-salt and 172±5 mm Hg in the high-salt angiotensin hypertension groups on day 14. EH inhibitor treatment significantly lowered blood pressure to 140±5 mm Hg in the normal-salt angiotensin hypertension group and to 151±6 mm Hg in the high-salt angiotensin hypertension group on day 14. The lower arterial blood pressures in the AUDA-treated groups were associated with increased urinary epoxide-to-diol ratios. Urinary microalbumin levels were measured, and ED-1 staining was used to determine renal damage and macrophage infiltration in the groups. Two weeks of AUDA treatment decreased urinary microalbumin excretion in the normal-salt and high-salt angiotensin hypertension groups and macrophage number in the high-salt angiotensin hypertension group. These data demonstrate that sEH inhibition lowers blood pressure and ameliorates renal damage in angiotensin-dependent, salt-sensitive hypertension.
A scheme for building a dataset for intrusion detection systems

One of the main challenges in developing a network-based intrusion detection system is collecting data for training the system. Although, some datasets such as KDD Cup 1999 have been collected and are in public, these datasets are out of date and unreliable for building a system in reality. In this paper, we propose a scheme for building online an intrusion detection dataset. The scheme allows us to collect the raw data from a controlled environment and then process to have 16 features (traffic and content features) with full labels. The collected dataset is called LUT13. We then applied two well-known machine learning techniques: Artificial Neural Network (ANN) and Fuzzy C-Means (FCM) to train the system based on this dataset. The system, after trained on LUT13, was tested on the real environment and compared with the system constructed based on KDD Cup 1999. The results show that our dataset helps the system achieves higher detection rate compared to KDD Cup 1999.
Retrieval performance in Ferret a conceptual information retrieval system

FERRET is a full text, conceptual information retrieval system that uses a partial understanding of its texts to provide greater precision and recall performance than keyword ,search techniques, It uses a machine-readable dictionary to augment its lexical knowledge and a variant of genetic learning to extend its script database. Comparison of FERRET’s retrieval performance on a collection of 1065 astronomy texts using 22 sample user queries with a standard boolean keyword query system showed that precision increased from 35 to 48 percent, and recall more than doubled, from 19.4 to 52.4 percent. l%is paper describes the FERRET system’s architecture, parsing and matching abilities, and focuses on the use of the the Webster’s Seventh dictionary to increase the system’s lexical coverage.
Optimal Energy Scheduling for Rate-Guaranteed Download Over Faded Multichannel Networks

In this contribution, we consider emerging wireless content delivery networks (CDNs), where multiple (possibly nomadic) clients download large-size files from battery-powered proxy servers via faded links that are composed of multiple slotted orthogonal bearers (e.g., logical subchannels). Since the considered transmit proxy servers are battery-powered mobile routers, a still open basic question deals with searching for optimal energy-allocation (e.g., energy scheduling) policies that efficiently split the available energy over the (faded) bearers. The target is to minimize the resulting (average) download time when constraints on the average available energy per information unit (IU), peak-energy per slot, and minimum energy per bearer (e.g., rate-induced constraints) are simultaneously active. The performance and the robustness of the resulting optimal energy scheduler are tested on the last hop of Rayleigh-faded mesh networks that adopt the so-called ldquodirty paper strategyrdquo for broadcasting multiple traffic flows that are generated by proxy servers equipped with multiple antennas .
Emulating the behavior of steam power plants using wind power stations to provide instantaneous and primary reserve: Providing ancillary services of steam power plants using wind power stations

Power generation using renewable resources is replacing conventional generation using steam power plants all over the world. Therefore a new control concept is shown, enabling a wind power station to behave just as like the synchronous generator in a steam power plant providing ancillary services. The main focus is on the provision of instantaneous and primary reserve and the ability to dampen grid power oscillations. Therefore only changes in the control of the inverter of the wind power station need to be performed. The results of detailed simulations are presented and an experimental test stand is shown.
They Don't Do it Often, But They Do it Well: Exploring the Relationship between Applicant Mental Abilities and Faking

Despite its scientific and practical importance, relatively few studies have been conducted to investigate the relationship between job applicant mental abilities and faking. Some studies suggest that more intelligent people fake less because they do not have to. Other studies suggest that more intelligent people fake more because they have increased capacity to fake. Based on a model of faking likelihood, we predicted that job candidates with a high level of mental abilities would be less likely to fake a biodata measure. However, for candidates who did exhibit faking on the biodata measure, we expected there would be a strong positive relationship between mental abilities and faking, because mental abilities increase their capacity to fake. We found considerable support for hypotheses on a large sample of job candidates (N=17,368), using the bogus item technique to detect faking.
Caregiver Characteristics and Perceptions, Quality of Interactions with Children, and Children's Development in Family-Like Orphan Care in South Africa

This mixed-methods study included a total of 49 children (birth to 5 years) and 28 caregivers from two family-like institutional care settings in KwaZulu-Natal, South Africa. The purpose of the study was to assess the associations between caregivers’ age, education, experience, depression, and social support and the quality of interactions they have with the young children in their care, and to test the associations between caregiver-child interaction quality and child attachment and growth outcomes. Results indicated that caregivers’ perceived social support from friends was positively associated with caregiver-child interaction quality. In addition, among HIV+ children, interaction quality was positively associated with children’s height z-scores, and regardless of children’s HIV status, interaction quality was positively associated with children’s weight z-scores. No other significant associations were found. The qualitative portion of the study included an in-depth exploration of caregivers’ perceptions of their role, their reports of challenges they experience, and the resources they desire. Caregivers’ discourse about what their role entailed included each of the six parental role beliefs that comprise Mowder’s (2005) Parent Development Theory. This study contributes to the institutional orphan care field by addressing the shortage of research on care and development in existing family-like care settings, and includes recommendations for future research, policy, and practice.
Toll-like Receptor 3 Expressed by Melanoma Cells as a Target for Therapy?

Purpose: The immunomodulatory properties of Toll-like receptors (TLR) agonists have inspired their use as experimental adjuvants for vaccination of cancer patients. However, it is now well recognized that TLR expression is not restricted to immune cells but can also be found in many cell types, including those giving rise to tumors. It is therefore mandatory to explore the potential effects of TLR triggering directly on tumor cells. Experimental Design: In the present work, we have investigated TLR3 protein expression in melanoma cell lines derived from patients, and analyzed the effects of TLR3 agonists on tumor cell survival. Moreover, we used RNA interference to stably knock down TLR3 expression and study the involvement of this receptor in dsRNA-induced effects on melanoma cells viability. Results: Human melanoma cells can express functional TLR3 protein. Interestingly, the engagement of the receptor by TLR3 agonists can directly inhibit cell proliferation and induce tumor cell death when combined to treatment with either type I IFN or protein synthesis inhibitors. These effects were shown by RNA interference to be largely dependent on TLR3. Moreover, TLR3-mediated cell death involves the activation of caspases and engages both extrinsic and intrinsic apoptotic pathways. Conclusion: TLR3 protein can be expressed in human melanoma cells, where it can deliver proapoptotic and antiproliferative signaling. Altogether, these results suggest that TLR3 agonists represent very promising adjuvants for cancer vaccines not only based on their well-described immunostimulatory properties, but also due to their newly identified cytostatic and cytotoxic effects directly on tumor cells.
The Sasa quelpaertensis Leaf Extract Inhibits the Dextran Sulfate Sodium-induced Mouse Colitis Through Modulation of Antioxidant Enzyme Expression

Background: Oxidative stress plays an important role in the pathogenesis of inflammatory bowel disease. The objective of this study is to investigate the protective effect of Sasa quelpaertensis leaf extract (SQE) against oxidative stress in mice with dextran sulfate sodium (DSS)-induced colitis. Methods: Mice were treated with SQE (100 mg/kg or 300 mg/kg body weight) by gavage in advance two weeks before inflammation was induced. Then, the mice were administered with 2.5% DSS in drinking water for 7 days and normal drinking water for 7 days between two DSS treatment. Disease activity index values, gut motility, and severity of the resulting oxidative DNA damage were analyzed. The antioxidant effect of SQE was evaluated by measuring malondialdehyde (MDA) and superoxide dismutase (SOD) activity in plasma samples. Catalase activity and expressions levels of glutathione peroxidase 1 (Gpx1), SOD1, and SOD2 were also detected in colon tissues. Results: Administration of SQE significantly reduced the severity of DSS-induced colitis compared to the control (Ctrl) group. Levels of 8-oxo-dG, an oxidative DNA damage marker, were significantly lower in the SQE group compared to the untreated DSS Ctrl group. In the SQE (300 mg/kg) group, MDA levels were significantly lower, while SOD and catalase activity levels in the plasma samples were significantly higher compared with the DSS Ctrl group. The expression levels of the antioxidant enzymes, SOD2 and Gpx1, were significantly higher, while the levels of SOD 1 expression were lower, in the colon tissues of the DSS Ctrl group compared with those of the Ctrl group. In contrast, administration of SQE significantly down-regulated SOD2 and Gpx1 expressions and up-regulated SOD1 expression. Conclusions: These results indicate that SQE efficiently suppresses oxidative stress in DSS-induced colitis in mice, and its action is associated with the regulation of antioxidant enzymes.
Roadmap to Communicating Knowledge Essential for the IndusTrial environment

The project ROCKET will prepare a strategic roadmap for future developments in organizational learning related to education of engineers and knowledge workers. It will prepare the ground for future Knowledge Management RTD activities in the upcoming framework program by investigating future research challenges and creating a vision; outlining a roadmap showing how to implement the ROCKET model with a minimum of risk or social fallout. Unlike some methods where the end-point is forecast, the roadmap process starts with the end-point or vision clearly in mind and then traces the alternative paths to achieve it. For the identification of this vision to be achieved an own work package 4 (vision identification) is scheduled in the work plan of ROCKET. This document is deliverable D4.2 " Final Report on Vision Identification " of work package 4 and outlines the intended approach and the ROCKET key scenarios as input for the preparation of the roadmap. Vision identification is essentially one activity, which has been broken down into two separate tasks for practical purposes: • Task 4.1: Initial vision identification This task will run from month 3 to month 6 and will end up with the production of an internal draft report, which will feed both the revision of the users requirements and the generation of the first version of the roadmap. • Task 4.2: Revision and full vision description This task will run from month 7 to month 9 and will end up with the production of the final version, describing in full the vision.
Increased PIO2 at Exhaustion in Hypoxia Enhances Muscle Activation and Swiftly Relieves Fatigue: A Placebo or a PIO2 Dependent Effect?

To determine the level of hypoxia from which muscle activation (MA) is reduced during incremental exercise to exhaustion (IE), and the role played by PIO2 in this process, ten volunteers (21 ± 2 years) performed four IE in severe acute hypoxia (SAH) (PIO2 = 73 mmHg). Upon exhaustion, subjects were asked to continue exercising while the breathing gas mixture was swiftly changed to a placebo (73 mmHg) or to a higher PIO2 (82, 92, 99, and 142 mmHg), and the IE continued until a new exhaustion. At the second exhaustion, the breathing gas was changed to room air (normoxia) and the IE continued until the final exhaustion. MA, as reflected by the vastus medialis (VM) and lateralis (VL) EMG raw and normalized root mean square (RMSraw, and RMSNz, respectively), normalized total activation index (TAINz), and burst duration were 8–20% lower at exhaustion in SAH than in normoxia (P < 0.05). The switch to a placebo or higher PIO2 allowed for the continuation of exercise in all instances. RMSraw, RMSNz, and TAINz were increased by 5–11% when the PIO2 was raised from 73 to 92, or 99 mmHg, and VL and VM averaged RMSraw by 7% when the PIO2 was elevated from 73 to 142 mmHg (P < 0.05). The increase of VM-VL average RMSraw was linearly related to the increase in PIO2, during the transition from SAH to higher PIO2 (R2 = 0.915, P < 0.05). In conclusion, increased PIO2 at exhaustion reduces fatigue and allows for the continuation of exercise in moderate and SAH, regardless of the effects of PIO2 on MA. At task failure, MA is increased during the first 10 s of increased PIO2 when the IE is performed at a PIO2 close to 73 mmHg and the PIO2 is increased to 92 mmHg or higher. Overall, these findings indicate that one of the central mechanisms by which severe hypoxia may cause central fatigue and task failure is by reducing the capacity for reaching the appropriate level of MA to sustain the task. The fact that at exhaustion in severe hypoxia the exercise was continued with the placebo-gas mixture demonstrates that this central mechanism has a cognitive component.
Feasibility of TBI Assessment Measures in a Field Environment: A Pilot Study for the Environmental Sensors in Training (ESiT) Project

Abstract : The present study compared a variety of TBI assessment methods to determine their feasibility for use in a military training field environment. Participants (N = 47) were assigned to one of two conditions. Condition 1 included neurocognitive performance tests (Continuous Performance, Symbol Digit Coding, Stroop and Four-Part Continuous Performance) and oculomotor tests (Pupillary Light Reflex and King-Devick). Condition 2 included the Integrated Display Enhanced Testing for Cognitive Impairment and mTBI (iDETECT), which includes neuropsychological performance, balance/sensory integration, and vestibular/oculomotor integrity tests within a multimodal system. Both conditions included the Military Acute Concussion Evaluation (MACE) and an Ease-of-Use survey. Mean scores for the Ease-of-Use survey and mean test administration times for each measure were compared. Administrative feedback was also considered for qualitative analysis. Results suggest that of the measures tested, the iDETECT is deemed most appropriate for use in the field environment. Therefore, the iDETECT will be used in a follow-up, correlational study.
