There is an argument in academic circles that the implied dutyof mutual trust and confidence will evolve to form an all-embracingsuper-principle under which each of the more ‘traditional’implied duties will rest, including the employer’s impliedduty to exercise reasonable care for the welfare and well beingof the employee. The theme of this article is that, on balance,there is no evidence for the emergence of the implied duty ofmutual trust and confidence as a super-principle. If anything,the recent trends in the case law emphasise the distinctivenessof the employer’s duties to exercise reasonable care andtrust and confidence. The article’s aim was to demonstratethat both duties are separate, free-standing duties, sittingon an equal plane in terms of importance. To rationalise one,or all of the implied duties (i.e. the duty to exercise reasonablecare and/or all of the other ‘traditional duties’),as one of the means by which the super-principle of trust andconfidence is, or may be expressed, is to a large extent, aspirational.  相似文献

Jorge Sanjinés' 1960s films Revolución and Ukamau challenge the class and ethnic hierarchies of Bolivian society by casting the proletarian and indigenous masses as revolutionary liberators. The new national imaginary they evoke is tightly bound to the experimental cinematic techniques they employ, since their rejection of rationalist, realist aesthetics signals a partial undermining of the linear time of the modern nation. Ukamau both recalls and resists previous Bolivian indigenismo, which sought to co‐opt the Indian into a national mestizo consciousness. Its exoticist portrayal of the Indian ultimately limits its political effectiveness, but textual and contextual analyses show subversive Indian agency leaking through.  相似文献

Decomposition studies were conducted using two carcasses of domestic pigs, Sus scrofa L., 8.4 kg and 15.1 kg in weight, to determine the effects of carcass size on the rate of decomposition, composition of the arthropod fauna, and succession patterns. A total of 46 arthropod taxa were recovered during this study. No size-related differences were observed between carcasses with respect to composition of the arthropod fauna or patterns of succession. A greater number of arthropods were observed attracted to the 15.1-kg carcass, and the rate of decomposition observed was more rapid for the 15.1-kg carcass than for the 8.4-kg carcass. Internal temperatures of the 8.4-kg carcass were more directly related to external ambient temperatures during the fresh and bloated stages of decomposition. During the decay stage, both carcasses generated internal temperatures significantly above ambient temperatures. Following this stage, internal temperatures fell to approximate ambient temperatures during the postdecay and remains stages.  相似文献

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations.  相似文献

Despite successive military regimes, state and local governmentsin Nigeria have been able to engage in limited forms of foreignaffairs activity. both directly abroad and indirectly throughinstitutions of the national government. The trend since independencehas been to make foreign affairs an exclusive responsibilityof the federal government. Generally, though, the military regimeshave been better able than the civilian governments to limitconstituent diplomacy. Under the Third Republic, therefore,state and local governments are likely to assert themselvessomewhat more in foreign affairs than they have recently.  相似文献

This paper argues that corruption is a product of self-aggrandizement; of unrealistically low remuneration which makes it impossible for public servants to live within their legitimate means; and of a closed political system which inevitably tends to exclude aggregated interests'. Corruption leads to loss of much needed revenue and human talent for development, distorts priorities for public policy, and shifts scarce resources away from the public interest. The mutual distrust that results among the different sections of society, and the growth of despondency in the general public, are incompatible with the requirements for successful public policy. The main theme running through the paper is that political instability, corruption and underdevelopment are mutually reinforcing. The paper finally outlines certain measures that need to be taken in order to clear the path for sustained growth and development.  相似文献
