公司治理的目的在于排除不正当的经营并提高经营的效率性。日本于2002年商法修改中引进了类似美国的执行官制度,并期待以此来促进经营的效率性。同时,值得注意的是,日本虽引进了该制度,但并没有强制性地要求所有股份公司必须采用它,公司可在原有的经营体制与新体制之间自行选择。这意味着,决定公司治理模式优劣的不是法律,而是市场,公司法的作用应该是为公司的发展扫除障碍,创造更大的发展空间。 相似文献

This article presents a semiotic analysis of the student perception of learning outcomes in British higher education. It centres on three annotated images in Frank Furedi’s article “The Unhappiness Principles”, published in Times Higher Education in 2012. Drawing upon Peircean semiosis and iconicity, it provides a rhetoric-infused interpretation of the word–image complementarity exhibited in student participants’ written commentaries on the three images. This leads to a dialectical view of formative and summative assessment, in which process and product create each other through the same continuum of learning and teaching. In highlighting intellectualism as central to the ethnography of university life, this article argues that learner autonomy and the potential for transformation is deemed essential to the student experience in higher education. 相似文献

将民族环境习惯法与国家法进行衔接和融合,既是少数民族地方环境法制建设的需要,也是民族环境习惯法现代化的合理进路。具体而言,三江源地区环境习惯法可以成为国家环境立法的来源,并有助于环境法律的实施,同时能够弥补环境立法的空缺。 相似文献

在RK-13细胞上培养的马动脉炎病毒(Equine viral arteritis,EAV)在4℃、室温和37℃条件下,用多种动物的红细胞进行血凝试验,病毒在不同温度下均可凝集小鼠和鸡的红细胞,但不能凝集牛、绵羊、山羊、马、猪、豚鼠、仓鼠、兔及鹅的红细胞.将病毒用吐温-80和乙醚处理后,血凝活力会显著增强,其HA效价比未经处理的病毒高4-8倍,且血凝像更加清晰.处理病毒的最适条件是在冰浴状态下用终浓度0.6-1.25 mL/L吐温-80振荡处理15-60 min,再加1/2体积的乙醚振荡作用5-15 min. 相似文献

Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability. 相似文献

This article examines the relationship between the populations of the more and less developed societies between the first century and 2100. Such an analysis reveals a changing dependency between the level of development (and GDP) achieved and population numbers between the first century and 1998. In relation to the past the article suggests a dynamic model for dividing the world into more and less developed areas. In relation to the present and the future it bases the population analysis on the developmental division of the world as published by one of the co-authors of this article. The article largely uses population estimates (with those referring to the past taken from Angus Maddison and those referring to the future from the most recent projections by the United Nations). Taking the 2013 UN projection as a model, it discusses three variants for demographic development in the North and South up to 2100. It argues that the more restrictive population growth variants of the UN projection predict a greater relative ‘Third Worldisation’ of the world than does the most dynamic projection. 相似文献

Trigger pull is the force that needs to be exerted on the trigger to discharge a firearm. The measurement of trigger pull can assist in the evaluation of the safety, function, and manufacturing characteristics associated with a firearm during the forensic firearm examination process. Nonetheless, the accuracy and uncertainty of trigger pull measurements may be affected by the measuring device, test procedure, and environmental conditions. In this work, an innovative finger-trigger interface device was developed to facilitate accurate trigger pull measurements. The idea was to reduce the variation related to the position of the measurement device on the trigger in existing measuring methods and devices. Three force sensors based on different technologies were initially evaluated. While two of the three sensors failed to produce data, the miniature capacitive plate sensor exhibited high precision and a linear response over the range of typical trigger pulls. To examine the effects of the finger-trigger interface on trigger pull measurement, different sensor housing prototypes were designed in silico and 3D printed for the construction of three finger-trigger interface devices. The performance of each finger-trigger interface device was evaluated by measuring the trigger pulls of several selected firearms and comparing the data to a previously published study. Our preliminary results demonstrated the novel finger-trigger interface device offered a new way to measure trigger pull in situ with acceptable accuracy and precision. 相似文献

The private nature of corporate actors does not necessarily preclude them from contributing to public interest. When business strategies and genuine public motivation are favorably aligned, corporate actors from the private sector can also drive public sector innovations. For a private corporation, policy entrepreneurship inherently entails crossing not only the public–private boundary but also various policy domains. This study formulates five propositions to characterize the cross-boundary strategies of corporate policy entrepreneurship, a distinct form of policy entrepreneurship in a developing authoritarian state. The case study of mobile healthcare payment innovation in China finds that the corporate entrepreneur used a series of cross-boundary strategies adeptly that eventually made the innovation not only adopted in one locality but also rapidly diffused nationwide. These strategies were not used in isolation or in a pure stepwise fashion but appeared to be recursive and interactive, suggesting the dynamic nature of corporate policy entrepreneurship in a multilevel governance system. More studies could be done to further examine strategies and processes of other forms of policy entrepreneurship in various national and sectoral settings. 相似文献
