Effects of Human Resource Practices on Organizational Performance. A Case of VETA in Dar es salaam and Morogoro Regions

This study entitled “The Effects of Human Resource Practice on Organizational performance: A case of Vocational Education Training Authority (VETA)” intended to assess effects of human resource practices such as Human Resource Planning (HR), training and career development and compensation policy and management on organizational performance in Tanzania public institutions. An exploratory research design was adopted as an appropriate study design. A sample of 100 employees was selected using purposive sampling and simple random sampling. An interview and self-administered questionnaire composed of closed and open-ended, and likert scale questions and documentary review instruments were used to collect data. Data were analyzed using descriptive statistics using excel for quantitative data. The findings indicated that the human resource practices such as HR planning, training and development, compensation policy, have a positive relationship with VETA institutions’ performance. The performance of both employees and the institutions depends on how managers use best practice on employees’ management. It was concluded that selected human resource practices work well if there is effective policies to assist managers when motivating staff to raise their working morale. It was recommended that the public sector institutions Governing Boards, should be competent so that they can supervise managements and sign performance contracts with managers and later appraise

Path analysis of the components of production jump, reproductive barriers - support in empowering rural cooperatives

Context and purpose.The main purpose of the research is to explain a model of the application of production jump components, removing obstacles in the empowerment of rural cooperatives in Kohgiluyeh and Boyerahmad province.Methodology/approach.The current research is of the hybrid-alignment type. In the qualitative part, 10 experts of the cooperatives were selected using the targeted sampling method. In the quantitative part of the research method, it is a survey and 249 members of the cooperatives were selected by simple random sampling.Findings and conclusions. The results of the theme analysis identified 6 main components of the production jump-removal of obstacles: social, economic, political-legal, managerial, educational, infrastructural indicators. The results of the structural equations showed that managerial-organizational indicators with a standard coefficient of 0.220 have the greatest impact; And legal-political indicators with a standard coefficient of 0.125 have the least impact on the empowerment of rural cooperatives. Therefore, it is possible to improve the performance of this sector by creating obstacles and paying attention to production indicators in the cooperative sector.Originality. In previous researches, factors affecting the success and performance of cooperatives were repeatedly discussed. In this research, while taking into account the indicators identified in previous researches, specifically, the indicators of production jump-obstacles in the light of the statements of the supreme leader of the revolution and the second step of the extraction revolution and their role in empowering rural cooperatives have been studied. The method and results of this research are innovative

Transferência de massa e secagem em leitos vibrofluidizados: uma revisão Mass transfer and drying in vibro-fluidized beds: a review

O desenvolvimento de tecnologias de processamento e equipamentos requer a utilização de novos métodos e melhor qualidade do produto processado. Dentro do processo de secagem contínua, a utilização de equipamentos que promovem incremento nos coeficientes de transferência, é a de maior interesse. O uso de energia vibracional tem sido recomendado para materiais dispersos. Assim, uma revisão da literatura sobre a transferência de massa e a secagem em leitos vibrofluidizados foi realizada, envolvendo resultados experimentais e modelagem matemática.<br>Development of processing technology and equipments requires new methods and better quality of the processed product. In the continuous drying process, utilization of equipments that promotes an increment in the transfer coefficients becomes of the major interest. The use of vibrational energy has been recommended to the dispersed materials. Such method is based on the use of vibrational energy applied to disperse media. Thus, a literature review on the mass transfer and drying in vibro-fluidized beds was carried out, showing experimental results and mathematical modeling
