Racial variation of aerobic and anaerobic performances in sedentary men  [PDF]
Salma Abedelmalek, Hamdi Chtourou, Asma Aloui, Zouhair Tabka, Nizar Souissi
Open Journal of Internal Medicine (OJIM) , 2012, DOI: 10.4236/ojim.2012.22023
Abstract: The present study was designed to compare the effect of racial variations on short- and incremental maximal exercises in sedentary men whites (WT) and blacks (BT) Tunisian and South African (SA). In a randomized order, thirty-six physically sedentary men including 12 BT, 12 WT, and 12 SA were asked to perform a force-velocity (i.e., determination of maximal power (Pmax), F0, and V0) and a treadmill maximal aerobic (i.e., determination of maximal oxygen uptake (VO2 max)) tests. Pmax and F0 were significantly higher in SA than WT (p < 0.01 and p < 0.05 respectively). However, no significant difference was observed between WT and BT and between SA and BT. Likewise, racial variations didn’t affect the V 0 values. Moreover, VO2 max was significantly higher in SA and BT than WT (p < 0.001). However, no significant difference was observed between SA and BT. Compared to white subjects, the present study’ results suggest the superiority of blacks races on aerobic and anaerobic exercises in physically sedentary men.
An Approach to Developing a Performance Test Based on the Tradeoffs from SW Architectures  [PDF]
Byoungju Choi, Miso Yoon, Heejin Kim
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.64024
Abstract:

In a performance test, the standards for assessing its test results are not sufficiently determined due to the lack of a well-structured test developing methods which are found in a functionality test. By extending the established workflow structure, this approach will concentrate on tradeoffs within T-workflow and further develop tests based on T-workflow. The monitoring and tuning point have also been investigated to understand the validity and performance of software. Finally through a case study, it has been shown that better assessment of software performance can be obtained with the suggested tests developed based on T-workflow and by locating its monitoring point and tuning point.

How a Proper Performance Related Reward System Can Contribute to Work Performance Excellence  [PDF]
Sara Indileni Hamukwaya, Rashad Yazdanifard
Open Journal of Business and Management (OJBM) , 2014, DOI: 10.4236/ojbm.2014.23023
Abstract: Performance related rewards came in picture in recent years for so many reasons. That includes rewards as motivation for employees to excel, reduce employer-employee conflicts and ensure fair reward treatments. This also includes a response to a call of worker’s dissatisfaction at work, poor work performance, negative attitudes, lack of motivation and agency problems. These “ills” will only be “cured” if there are proper performance measures in place. This study examined how a proper performance related reward system can be used as a tool to enhance work performance. The study include different performance related reward systems that may be embraced by management to foster work performance, what performance appraisal measures need to be put in place and the relationship between performance related reward systems and work performance. The benefits of embracing the Performance based rewards are also discussed.

Journal of Human Resource and Sustainability Studies (JHRSS) , 2018, DOI: 10.4236/jhrss.2018.62034
Abstract: The relationship between self-efficacy and job performance has long been established. But, there is limited research on self-efficacy and different dimensions of job performance and the extent of the association has not been investigated comprehensively in the context of the Sri Lankan banking sector. Therefore, the purpose of this study was to investigate the impact of self-efficacy on task performance and contextual performance of the employees in the banking sector in Sri Lanka. The data were randomly collected from a sample of 176 managers and 357 non-managerial employees in the banking sector in Sri Lanka. A questionnaire was administered to the employees to measure their self-efficacy, task performance, and contextual performance. The collected data were analyzed using correlation coefficient and regression analysis. The results of the study indicated that self-efficacy had significantly and positively correlated with task performance and contextual performance. According to the findings, the employees’ trust on their capabilities to organize and execute courses of action required to accomplish the task has significantly and positively correlated with the behaviors that are directly related with the completion of the job and with the extra role supporting behaviors which are not directly related to the job.

International Online Journal of Educational Sciences , 2010,
Abstract: This research has been conducted to detect the opinions of teachers and administrators towards the implementations of teacher performance management applications at public and private high schools. In the study, it has been examined that whether opinions of teachers and administrators towards the implementation of teacher performance management applications at public and private high schools differ according to school type, title and of teachers at each school and education level. 74 administrators and 423 teachers working at either public or private schools in Ankara participated in the research. Arithmetical average, t test and two-factor variance analysis techniques have been used in data analyzing. According to results of the study, opinions of teachers and administrators towards the implementation of teacher performance management applications at public and private high schools differ according to school type and task. When the mutual effect of school type and task variables are examined together, it has been viewed that the mutual effect has not is not meaningful about the perceptions of implementation level. Whilst perceptions of public high school teachers’ of performance management applications change within their own school types, it does not differ in view of private high schools.

Clever Ketlogetswe, Jerekias Gandure
Smart Grid and Renewable Energy (SGRE) , 2011, DOI: 10.4236/sgre.2011.22019
Abstract: Research in biodiesel production has been motivated by several reasons including consistant increase in prices of petroleum diesel, environmental advantages, security of fuel supply, and employment creation. This paper presents a review of one alternative technological method that can be used to produce this fuel. Biodiesel from used cooking oil was produced by alkali catalyzed transesterification process. Performance of internal combustion engine using this bio-diesel blended with petroleum diesel in various blending ratios was performed. The engine performance studies were conducted on a variable compression engine test rig with automatic data acquisition set up. Parameters such as brake power, torque and fuel consumption were measured at different loads for pure petroleum diesel, pure biodiesel and different combinations of the dual fuel. The test results indicate that the performance of the engine is comparable for all the fuel mixtures under review

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2010, DOI: 10.4236/ijcns.2010.33037
Abstract: A mobile ad-hoc network is an autonomous collection of mobile nodes that communicate over bandwidth constrained wireless links. Due to nodal mobility, the network topology may change rapidly and unpredictably over time. The routing protocols meant for wired network cannot be used for mobile ad-hoc network because of mobility of network. A number of routing protocols like Destination-Sequenced Distance-Vector (DSDV), Ad-Hoc On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Temporally Ordered Routing Algorithm have been implemented. The ad-hoc routing protocols can be divided into two classes; Table-Driven and On-Demand. This paper examines two routing protocols for mobile ad-hoc networks—the Destination Sequenced Distance Vector (DSDV), the table-driven protocol and the Ad-Hoc On- Demand Distance Vector routing (AODV), an on-demand protocol and propose an algorithm that facilitates efficient routing of the packet and failure recovery mechanism

Abstract: The quest for biofuel production and use in Botswana is driven by factors including volatile oil prices, need for fuel security, potential for job creation, potential reduction in greenhouse gas emissions, and economic diversification. In line with national efforts to come up with energy sources that are both environmentally friendly and sustainable, this work was carried out to compare performance properties of native crude marula (Sclerocarya birrea) seed oil and petrodiesel fuel on a variable compression engine test rig with automatic data acquisition set up. Parameters such as engine torque, brake power and specific fuel consumption were measured at different loads for the two fuels. The results indicate that engine performance when powered with crude marula oil compares favourable with those for petrodiesel. Optimum numerical values for engine torque, brake power and specific fuel consumption were 28.2 Nm, 6.27 W and 0.34 g/kWh respectively for petrodiesel, and 22.7 Nm, 6.6 W, 0.33 g/kWh respectively for crude marula oil. The engine performance was also analysed for same parameters, namely, engine torque, brake power and specific fuel consumption when powered using the same fuels over a range of compression ratios while the load was fixed at 80%. Optimum numerical values for engine torque, brake power and specific fuel consumption were 27.2 Nm, 3.67 W and 0.59 g/kWh respectively for petrodiesel, and 26.3 Nm, 3.6 W, 0.34 g/kWh respectively for crude marula oil. The results indicate that compression ratio of 16:1 yields optimum engine performance in terms of engine torque and brake power for both fuels under review. However, marula oil fuel recorded smooth steady increase in performance profile across all compression ratios which out-performs petrodiesel on lower compression ratios for engine torque and brake power, and is largely better than petrodiesel on fuel consumption.
Does Cluster Membership Enhance Financial Performance?  [PDF]
William Ruland
iBusiness (IB) , 2013, DOI: 10.4236/ib.2013.51001
Abstract:

This paper reports upon the profitability of firms that locate their headquarters in same-industry geographic concentrations or clusters and those that opt to maintain headquarters in other locations. While the preponderance of the theoretical and descriptive literature emphasizes the potential benefits associated with clustering, some papers suggest that clustering should not be beneficial, at least for particular types of firms in particular circumstances. This empirical study, which examines a sample of more than 4000 Compustat firms from 86 different industries, compares the profitability of firms in industry clusters and firms in other locations. The sample is partitioned into small and large firms to account for expected differences in profitability, in general, and the possible differential impact of geographic clustering. The results show that for smaller firms, the profitability of cluster members tends to be considerably lower than for firms that opt not to join clusters. For the subsample of larger firms, the results are mixed depending upon the measure of profitability. The results imply that smaller firms should carefully evaluate the decision to locate in industry clusters.
