Bioaerosol data is often used in cases of building mold infestation alleging damage or adverse health effects upon occupants, despite the lack of consistent sampling and analytical protocols and numerical health-based standards. The most fundamental problem in these scenarios is defining a “significant” difference between a suspect indoor environment and the reference environment, regardless of the type of sampling and analysis utilized. Data interpretation focused upon differences in absolute numerical concentrations of fungi is subject to wide differences in expert opinion. On the other hand, an objective quantification of differences can be expressed in terms of probability and better meets criteria established in evidentiary rules. 相似文献

The 2003 Duma election resulted in the victory of the party of power, thereby strengthening managed democracy in Russia. Since then, political trends in Russia's regions and rural politics provide considerable evidence of the increasing ability of pro-Kremlin forces to maximise their electoral fortunes in national contests. These political trends make it likely that United Russia will not only emerge as the dominant party in the 2007 Duma election, but will provide the Kremlin and Putin's successor with a compliant lower house. The outcome is that Putin's successor will find the political infrastructure to continue managed democracy. 相似文献

There is a danger that the Rule of Law Assistance Unit of the United Nations Peacebuilding Commission will employ the same dominant but problematic paradigm that the international development community has pursued across the globe. This top-down, state-centred paradigm, sometimes known as ‘rule of law orthodoxy’, stands in contrast to an alternative set of strategies: legal empowerment. Legal empowerment involves the use of legal services, legal capacity-building and legal reform by and for disadvantaged populations, often in combination with other development activities, to increase their freedom, improve governance and alleviate poverty. It is typically carried out by domestic and international non-governmental organisations (NGOs), but also by governments and official aid agencies. This alternative approach focuses directly on the disadvantaged and integration with other development activities, which means it often operates under the de facto rubric of social development. Legal empowerment strategies vary among countries and NGOs. But their impact includes reforming gender-biased, non-state justice systems in Bangladesh; ameliorating the legal system's corruption in post-conflict Sierra Leone; keeping the human rights flame burning in post-conflict Cambodia; advancing natural resources protection and indigenous peoples' rights in Ecuador; and strengthening agrarian reform in the Philippines. Addressing such priorities can help alleviate poverty, ameliorate conflict and prevent chaos or repression from dominating the disadvantaged, particularly in conflict or post-conflict societies. 相似文献

Der Begriff der Landeskultur umfasst alle Maßnahmen zur Verbesserung der land- und forstwirtschaftlichen Nutzung des Bodens einschließlich der Erhaltung der Kulturlandschaft. Landeskultur ist somit alles Planen und Handeln mit dem Ziel, die Umwelt als gegebenes Naturraumpotential, insbesondere Wasser, Boden, Luft und die dazugehörigen Natur-, Kultur- und Sachgüter optimal zu erhalten, gestalten und rationell zu nutzen sowie dieses Potential mit bestmöglicher Qualität als natürliche und kulturelle Lebensgrundlage für die Allgemeinheit nachhaltig zu sichern. Landeskultur dient somit auch der Belebung und Werterhöhung der gebauten und gepflanzten Umwelt. Dies schließt auch und gerade die kulturelle Seite einschließlich Kulturlandschaften mit ein. Dabei ist es bis zur Überprüfung durch das BVerfG noch hinnehmbar, dass der Begriff „Landeskultur“ in Art. 89 Abs. 3 GG wegen der Mischkompetenz von Bund und Land vom BVerwG enger ausgelegt wird als in anderen Rechtsvorschriften. 相似文献

Catalona revolves around ownership of tissue samples provided by patients for research purposes, raising significant ethical and legal questions concerning patient rights, current human research practices, and the treatment of samples as capital resources by the research institution. 相似文献

Here we consider two ways that nanomedicine might be disruptive. First, low-end disruptions that are intrinsically unpredictable but limited in scope, and second, high end disruptions that involve broader societal issues but can be anticipated, allowing opportunity for ethical reflection. 相似文献

This synoptic article focuses on the origin and functioning of the Office of the Family Advocate as the protector of the interests of minor children in divorce cases. Attention is paid to the general contemporary trend to specialise in judicial decision-making that developed out of an increasing need for expertise in the administration of justice. A number of arguments for and against judicial specialisation are addressed. The origin of the Office of the Family Advocate within the South African judicial system is discussed and a brief exposition of the history of divorce legislation in South Africa is given. This is followed by attention to the functioning of the Office of the Family Advocate with reference to the process followed in investigations of this office and points of criticism against the system are highlighted. The article closes with an indication of the need for research in this regard and possible focus points for future research are identified. 相似文献

We consider the problem of drawing inferences within a legal framework when a person is a suspect for two separate offences. Although we are primarily concerned with scientific evidence the issue inevitably arises as to how that evidence interacts with other, non-scientific evidence. We show that, in this particular context, the evidence can be conveniently classified into three categories that concern, respectively: the first crime only; the second crime only; and evidence that relates to similarities between the two crimes. Two case examples are considered and we consider DNA, fibres and eyewitness evidence. These are viewed from the perspective of a prosecutor who has to decide whether or not to charge a suspect with one or both crimes. Graphical sensivity analyses are presented which have features that are not intuitively obvious. 相似文献
