Abstract

This study aimed to investigate farmers’ attitudes and skills of farm management. Two scales were constructed as an instrument for data collection, based on a sample of 100 farm units. Cronbach's alpha coefficients were .84 or higher, which indicated that the instrument scales were internally consistent. Non-parametric tests were used to analyze the data. Operators appeared to be largely commercial, but they did not highly rate the significance of farming as a business, or their level of management skills. Two-thirds of respondents perceived technical skills as the key to success. Poor management skills limit the operators’ ability in making informed decisions, planning and analyzing the financial performance of their operations. Farm management extension enhances farmers’ willingness and ability to make successful changes to their management practice. Improvement programs have to be targeted to the groups of operators who are more favorable to management extension, that is, full-time farmers, renters, the more experienced, the educated and the more dependent on farm income.  相似文献

Litsea elliptica Blume has been traditionally used to treat headache, fever, and stomach ulcer, and has also been used as an insect repellent. The acute and subacute toxicities of L. elliptica essential oil were evaluated orally by gavage in female Sprague-Dawley rats. For the acute toxicity study, L. elliptica essential oil was administered in doses from 500 to 4 000 mg/kg (single dose), and in the subacute toxicity test, the following doses were used: 125, 250, and 500 mg/kg, for 28 consecutive days. In the acute toxicity study, L. elliptica essential oil caused dose-dependent adverse behaviours and mortality. The median lethal dose value was 3 488.86 mg/kg and the acute non-observed-adversed-effect level value was found to be 500 mg/kg. The subacute toxicity study of L. elliptica essential oil did not reveal alterations in body weight, and food and water consumptions. The haematological and biochemical analyses did not show significant differences between control and treated groups in most of the parameters examined, except for the hemoglobin, mean cell hemoglobin concentration, mean cell volume, mean cell hemoglobin, serum albumin, and serum sodium. However, these differences were still within the normal range. No abnormalities or histopathological changes were observed in the liver, pancreatic islet of Langerhans, and renal glomerulous and tubular cells of all treated groups. In conclusion, L. elliptica essential oil can be classified in the U group, which is defined as a group unlikely to present an acute hazard according to World Health Organization (WHO) classification.  相似文献

In 2003, the Malaysian Government announced the policy of Teaching of Mathematics and Science in English [ETeMS or better known by its Malay acronym, Pengajaran dan Pembelajaran Sains dan Matematik dalam Bahasa Inggeris (PPSMI)]. The policy has, however, caused a furore, with both Malay nationalists and Chinese educationists treating the decision as an attack on their identity. Later in July 2009, the Malaysian Government announced to reverse the PPSMI policy starting from 2012. Researchers have long understood news as an artefact of a socially constructed reality. In making news, journalists shape a reality that reflects the political economic and ideological boundaries within which they work. By employing framing as the theoretical framework and content analysis as the research method, this study examined what pictures newspapers have created for citizens' understanding of the reversal of PPSMI policy. It was found that the mainstream newspapers framed the issue in similar ways, which was to explain and justify the reversal. Meanwhile, the alternative newspaper reflected what was mostly left outwhile the alternative newspaper reflected what was mostly left out and provided a counter-hegemonic discourse.  相似文献

Counselor education doctoral students (CEDSs), like other doctoral students, need assistance and support to ensure their self-care. One area markedly affecting self-care is one’s relationships with others. The purpose of this article is to examine the multiple relationships involved within CEDSs supervision, the potential areas to utilize peer support, and to propose peer support as an intervention for CEDSs. The authors discuss implications for using peer support to negotiate issues such as multiple relationships while being a CEDS and propose a call for research into the use of peer support as an effective approach to managing multiple relationships.  相似文献

Enterprise content management (ECM) systems are implemented in many organizations to deal with the complexity of the structured and unstructured organizational data. The little available ECM literature shows that many organizations using ECM focus on short-term benefits while strategic decision-making benefits are rarely considered. Although the relationship between the use of ECM and decision support (DS) is investigated recently, there is scarcity in research that investigates the categories of DS capabilities that ECM systems may have. The objective of this paper is to determine whether ECM systems can have the DS capabilities of four categories of decision support systems, namely classic decision support systems (DSS), executive information systems (EIS), expert systems (ES), and group decision support systems (GDSS). The findings indicate that ECM systems can have all decision support capabilities of classic DSS, EIS, and ES. However, ECM systems can have only a portion of decision support capabilities of GDSS.  相似文献

Recent advance in medical education is in correlation with the advances in information technology and thus computer-based learning is being increasingly employed. The objective of the present study was to design and evaluate an e-learning module in anatomy and assess the perceptions of students and faculty about this e-learning module. The participating students were randomized into three groups by block stratified randomization and Google groups were created for each of the three groups. The e-learning module was implemented in three sessions by rotating the three groups. Validated questionnaires were sent to faculty and participating students via Google forms to obtain feedback. The results of ANOVA showed that there was a significant difference among the groups in terms of marks obtained with conventional (F = 2.403, P = 0.103), online (F = 6.050, P = 0.005), and blended (F = 5.801, P = 0.006). Post hoc comparisons using the Tukey HSD test, about the gain of knowledge, indicated that the results were insignificant when comparing the conventional group with the online group, but were significant when comparing the blended group with the conventional and online group. The qualitative data regarding the perception of students toward e-learning were analyzed using thematic analysis. The introduction of an interactive e-learning module in anatomy was effective and well received by the students and faculty. The study showed that blended learning has a positive impact on the students' learning by improving cognitive gain and receptive perception for e-learning.  相似文献
