One way to ensure food safety is by enhancing compliance at the farm level. This study investigates the status, estimates the cost, identifies the determinants, and assesses the impact of compliance with food safety measures (FSM) in milk production in Nepal. The study is based on primary data collected from six high milk producing districts that captures the geographical and institutional diversity of milk production. Results show that the status of farm level compliance with FSM is not very encouraging. Also, the intensity of adoption of FSM exhibits significant inter- and intra-district variations. It varies positively with herd size but the additional cost of compliance with FSM varies negatively with herd size. Among other determinants, access to information, and incidence of inspection for conformity with safety and quality standards are also associated with higher adoption of FSM. Finally, we also estimate the impact of FSM on farm-gate prices and farmers’ profits and conduct several robustness checks. 相似文献

We present the results of flight simulator experiments (60 runs) with randomly selected airline pilots under realistic operational conditions and discuss them in light of current fuel regulations and potential fuel starvation. The experiments were conducted to assess flight crew performance in handling complex technical malfunctions including decision-making in fourth-generation jet aircraft. Our analysis shows that the current fuel requirements of the European Aviation Safety Agency (EASA) are not sufficient to guarantee the safety target of the Advisory Council for Aviation Research and Innovation in Europe (ACARE), which is less than one accident in 10 million flights. To comply with this safety target, we recommend increasing the Final Reserve Fuel from 30 min to 45 min for jet aircraft. The minimum dispatched fuel upon landing should be at least 1 h. 相似文献

产学研相结合的人才培育模式是培养高层次、复合型物流人才,解决我国物流人才缺口的关键。但我国目前的物流人才培养模式以及一对一为主的产学研培养模式仍存在着一定的问题需要解决。文章首先分析了我国目前物流人才培养过程中的基本问题,进而针对校企合作的产学研模式及其存在的主要问题进行了探讨。在此基础上,提出了解决这些问题的途径——建立区域联合物流人才培养实践基地的战略思考,并分析了该战略在运作模式、服务范围、资源利用、培养方式、协作关系以及功能拓展等方面的独特优势。 相似文献

This study proposes and tests a conceptual model that investigates the mediating effect of safety motivation linking psychological contract of safety (PCS) as manifested by employer obligations of safety and employee obligations of safety to safety violations and safety creative performance (SCP). Data were collected from a sample of flight attendants with two weeks time lag in Iran. Underpinned by social exchange theory, the results of structural equation modeling revealed that safety motivation fully mediates the simultaneous effects of PCS indicators on safety violations and SCP. Specifically, indicators of PCS jointly enhance safety motivation. In turn, safety motivation reduces safety violations, while enhancing SCP. Theoretical and practical implications evoked from the results advance existing knowledge of organizationally social interactions in promoting safety and the motivational mechanism through which PCS predicts employees' safety performance outcomes. 相似文献

In this article, we investigate the presence of possible complementarities between investments in information technology (IT) and firm-sponsored training using economy-wide longitudinal representative workplace-level data. Since information on the firm’s capital stock is often missing in such representative data, we match our workplace records to tax data to construct measures of the firm’s capital stock. We find some evidence of positive complementarities between investments in human capital and IT, suggesting that on-the-job training can also have a positive impact on productivity when complemented with investments in CAD or other technologies. 相似文献

In this diary study, we examined a theoretical model in which the psychological conditions of meaningfulness, availability, and safety serve as mechanisms through which the work context during discrete situations within the workday influences “state” engagement. We further theorised that a person's “trait” level of engagement would exert cross‐level effects on the state level relationships. Multilevel analyses based on a sample of 124 individuals in six organisations and 1,446 situational observations revealed that meaningfulness and availability (but not safety) mediated the relationships between perceptions of the work context and state engagement. High levels of trait engagement strengthened the within‐person relation between availability and state engagement, yet weakened the within‐person relation between meaningfulness and state engagement, suggesting two different processes may be at play. Overall, the findings advance our understanding of engagement as a multilevel and temporally dynamic psychological phenomenon and promote a contextually based HRM approach to facilitating engagement. 相似文献
