An economic evaluation of market development programmes for US dairy products

‘This study measured the effectiveness of US dairy export promotion programmes on increasing foreign demand and enhancing producers’ revenues. An import demand equation based on panel data was used to test whether export promotion has a positive and significant impact on US dairy exports. The effects of various promotion scenarios on the dairy market were then simulated, and benefit–cost ratios (BCRs) for these programmes were estimated. There were three key findings. First, the combined effort of public and private dairy export promotion expenditures had a positive and statistically significant impact on demand for US dairy products in the world market. The findings indicated that export promotion stimulated total dairy exports by 4.14 billion pounds, on average, per year, which represented 55.8% of total exports. Second, US dairy export promotion has been highly profitable for the nation’s dairy farmers. The calculated BCRs, based on assumed elasticity of supply, ranged from a low of 8.54 for the most elastic assumption to a high of 30.12. Third, from an optimality standpoint, dairy farmers are underinvesting in export promotion. The marginal BCRs ranged from a low of 3.79 to a high of 15.22, which means that, at the margin, increasing export promotion expenditures would be profitable for dairy farmers.     

补偿还是自主:互联网技术嵌入与工作压力作用机制变迁研究

本文基于“中国社会态度与社会发展状况调查”2014年的数据,从奖酬模型、工作要求-控制模型两个工作压力经典模型出发,考察了互联网技术轻度嵌入群体和重度嵌入群体在工作压力作用机制方面的异同.研究结果表明相较于轻度嵌入群体,互联网技术重度嵌入群体具有更高的群体同质性—以受过高等教育的未婚青年为主,更有可能承担高水平的工作压力,且工作压力作用机制具有一定的特点.如传统上具有一定缓解作用的奖酬模型不再显著;在工作要求-控制模型中,本应具有正向作用的团队合作因其带来额外的情感劳动而成为提升压力感的变量,仅有灵活工作时间仍然有利于劳动者工作压力的缓解.这意味着随着互联网技术的深入引入,工作的方式方法和内在机制都在发生变化.     

Firm location,political geography and environmental information disclosure

As the subjective and objective factors that influence corporate behaviours, political region and firm location are of great importance to environmental information disclosure (EID). With spatial and political geography as a research perspective, this article makes a study by using the samples of manufacturing listed companies from 2009 to 2011. As a result, we determine that regulatory distance and political geography had negative effects on EID, while political geography weakens regulatory distance’s function. After considering an enterprise’s administrative rank, we determined that when the rank is higher, regulatory distance has negative effects on EID; when the rank is lower, the effects are the opposite. Regarding political geography, it always weakened the regulatory distance’s function. Moreover, the effects are significant only when the enterprises had low governmental regulation. The study shows the effects that firm location and political geography have made on EID. At the same time, this study also gives theoretical and empirical evidence to the necessity of raising governmental regulatory effectiveness.

机械密封式电缆贯穿件研制

核电站、核反应堆等核装置为了防止放射性物质外泄,在电缆穿墙(壁)时采用电缆贯穿件进行隔离。通常电缆贯穿件需将电缆截断采用插接件进行密封,插接式电缆贯穿件密封性能容易保证,密封可靠,泄漏率可达到极小。但加工零件多、精度要求较高,制造成本高。特别是对于大电流动力电缆和要求较高的信号同轴电缆,容易产生插接电极发热过大和信号衰减。为了满足工程需要,采用不截断电缆,不破坏电缆护套,本文研制了一套试验样机。样机经过密封性能、电气性能和抗震试验的验证。样机的的各项技术指标满足工程要求,泄漏率小于1×10-7Pa.m.3s-1。
