Personal And Social Competence

The purpose of this study is to describe the performance of professional teachers (post-certification) after obtaining a certificate of professional educators as well as allowances. The main competencies of professional teachers can be assessed by 6 capabilities, including the ability to implement the lesson, create modules and instructional media, preparation of RPP, personal and social competence, liveliness in academic organization and academic achievement development capability. This study is a model study of the Goal-Free Evaluation Model. The study population is all teachers of SMP who have passed the certification in Aceh Besar District. Sampling is done purposive sampling to teachers of science lessons in Secondary Schools in Aceh Besar District. Headmaster Principals are also involved to assess teachers' performance on the aspects of instructional administration. Data were collected using questionnaire, then analyzed using quantitative and qualitative descriptive technique. The results showed from 6 Aspects of assessment, four aspects of them are learning ability, modules and learning media, preparation of RPP, personal and social competence have shown high performance. However two others namely liveliness in professional organizations and the development of academic achievement, still in low performance. Hopefully these results can be input for the Office of Education of Aceh Besar Regency as a basic material for improving the quality of education in terms of improving the performance of Professional Teachers in Aceh Besar Regency.

Selected Traits

Artificially selected lines are widely used to investigate the genetic basis of quantitative traits and make inferences about evolutionary trajectories. Yet, the relevance of selected traits to field fitness is rarely tested. Here, we assess the relevance of thermal stress resistance artificially selected in the laboratory to one component of field fitness by investigating the likelihood of adult Drosophila melanogaster reaching food bait under different temperatures. Lines resistant to heat reached the bait more often than controls under hot and cold conditions, but less often at intermediate temperatures, suggesting a fitness cost of increased heat resistance but not at temperature extremes. Cold-resistant lines were more common at baits than controls under cold as well as hot field conditions, and there was no cost at intermediate temperatures. One of the replicate heat-resistant lines was caught less often than the others under hot conditions. Direct and correlated patterns of responses in laboratory tests did not fully predict the low performance of the heat selected lines at intermediate temperatures, nor the high performance of the cold selected lines under hot conditions. Therefore, lines selected artificially not only behaved partly as expected based on laboratory assays but also evolved patterns only evident in the field releases.

Multicriteria Decision Problems

Using additive models for aggregation of criteria is an important procedure in many multicriteria decision methods. This compensatory approach, which scores the alternatives straightforwardly, may have significant drawbacks. For instance, the Decision Maker (DM) may prefer not to select alternatives which have a very low performance in whatever criterion. In contrast, such an alternative may have the best overall evaluation, since the additive model may compensate this low performance in one of the criteria as a result of high performance in other criteria. Thus, additive-veto models are proposed with a view to considering the possibility of vetoing alternatives in such situations, particularly for choice and ranking problems. A numerical application illustrates the use of such models, with a detailed discussion related to real practical problems. Moreover, the results obtained from a numerical simulation show that it is not so rare for a veto of the best alternative to occur in the additive model. This is of considerable relevance depending on the DM's preference structure.

AbstractManagers face risk in explorative decision-making and those who are better at such decisions can achieve future viability. To understand what makes a manager effective at explorative decision-making requires an analysis of the manager’s motivational characteristics. The behavioral activation/inhibition system (BAS/BIS), fitting the motivational orientation of “approach” or “avoidance,” can affect individual decision-making. However, very little is known about the neural correlates of BAS/BIS orientation and their interrelationship with the mental activity during explorative decision-making. We conducted an fMRI study on 111 potential managers to investigate how the brain responses of explorative decision-making interact with BAS/BIS. Participants were separated into high- and low-performance groups based on the median exploration-score. The low-performance group showed significantly higher BAS than that of the high-performance group, and its BAS had significant negative association with neural networks related to reward-seeking during explorative decision-making. Moreover, the BIS of the low-performance group was negatively correlated with the activation of cerebral regions responding to risk-choice during explorative decision-making. Our finding showed that BAS/BIS was associated with the brain activation during explorative decision-making only in the low-performance group. This study contributed to the understanding of the micro-foundations of strategically relevant decision-making and has an implication for management development.

Test anxiety and distress occupy pivotal positions in students' lives today, because of over emphasis on academic achievement in the modern educational system. The need for high performance in examinations has defeated the very purpose of education. The SSC examination has come to be an exhaustive exercise that makes the students learn by rote rather than comprehension. There are a few who feel completely trapped in their situation and indulge in self-destructive acts like suicide. The present research study attempted at understanding the likely role of personality correlates namely, academic self-concept, self-efficacy and locus of control in alleviating the different dimensions of stress encountered by students of standard X. It revealed a significant relationship between stress and the mentioned variables and could have important implications in helping students of standard X come to terms with their invaluable self-worth in effectively coping with the evil of the present century -stress.

Microchannel Cooling

In the continuing effort to alleviate the increasing thermal loads for power electronics devices, numerous aggressive solutions have been developed, such as small-scale micro-channel heat exchangers. Although these methods can improve overall surface heat transfer to the order of 500 W cm−2, they are limited to single-sided cooling due to the typical wire-bonded electrical connections of the devices. Power overlay (POL) technology provides a stable planar structure for electrical connection, as well as attachment of an additional top-side heat exchanger. This study presents an analysis of double-sided microchannel cooling of a power electronics module. Two optimized, integral micro-channel heat sinks were attached above and below silicon power devices, with more traditional attachment on one side and a POL interface on the other. A compliant TIM was selected for low thermal resistance and good mechanical response, which allowed top-side connection to the POL surface. A theoretical model is presented that predicts the benefit of double-sided cooling based on the known performance of a single-sided heat sink and given addition thermal contact resistance for the top side. For microchannels with water, an enhancement of 26% was predicted. An experiment was also carried out to measure the actual performance benefit seen with double-sided cooling. An enhancement of over 30% was measured for a particular design. As the theory predicts, the benefit of double-sided cooling is limited for high performance designs. However, double-sided cooling could lead to high levels of thermal performance using low-performance technology.
