节能环保住宅评价指标体系构建研究 总被引:1,自引:0,他引:1
节能环保住宅已经渐渐成为建筑住宅发展的新方向,构建符合我国实际国情的节能环保住宅的评价指标体系,对于促进节能环保住宅的发展具有重要的意义。本文分析了我国节能环保住宅指标评价体系存在的问题,借鉴美国节能环保住宅相关评价标准与政策法规,提出了构建我国节能环保住宅评价指标体系的初步设想。 相似文献

The recent formation of a United Kingdom and Irish working group, the Body Fluids Forum (BFF), highlighted the need to investigate different working practices prior to any inter-laboratory comparison work and identification of best practice. Various dilutions of semen were seeded onto swabs and cloth samples for each BFF member laboratory to test using their standard techniques. The results showed that the detection of acid phosphatase on swabs is best achieved using direct testing rather than on an extract from the swab. Extraction methods for spermatozoa require a balance to be achieved between using a sufficient volume of water to ensure optimal release and minimal volume to ensure a concentrated extract. PSA tests were investigated and found to be more sensitive than Choline. DNA profiles were obtained from samples in which no spermatozoa had been detected during microscopic examination. 相似文献

Ethical principles are often presented as universal, immutable rules. However, when conducting research with ethnic minority
groups, such as Asian Americans and immigrants, ethical issues need to be placed within a sociocultural context as ethical
responses are filtered through the specific value orientations and belief systems of the ethnic group under study. Further,
when the group is a marginalized population, power dynamics complicate ethical principles of autonomy. The complexities are
further accentuated with sensitive topics such as intimate violence or domestic violence. Consequently, ethical questions
about autonomy, informed consent, confidentiality, limits to confidentiality, and protecting participants’ safety and reducing
distress need to be at the forefront when planning intimate violence research. An overview of sociocultural context of Western
biomedical ethics is presented and specific ethical issues that emerge when conducting intimate violence are discussed. 相似文献

The testing of oral fluid for drugs of abuse has increased significantly over recent years and is now commonplace in drug rehabilitation clinics, the workplace, prisons and custody suites. The global problem of identifying drugged drivers has also led to an increase in oral fluid testing at the roadside. The main requirements for the implementation of roadside drug testing are a rapid sample collection time, collection of a known sample volume and recovery of drugs from the collection device. We report here the development of the Cozart® DDS oral fluid collector, an oral fluid collector that combines rapid and adequate sample collection with satisfactory drug recovery. Oral fluid was collected from drug users (n = 134) and drug-free individuals (n = 137), using the Cozart® DDS oral fluid collector. The mean time for the completion of collection (full coloration of the sample presence indicator) was 34 s for drug-free individuals and 44 s for drug users. The average volume collected was 0.34 mL (n = 271). No chemical stimulant (to induce salivation) was used to achieve the collection times observed in either the drug-free or the drug-taking sample populations. Drugs were extracted from the collector using the Cozart® DDS buffer and drug recovery was determined by Cozart® enzyme immunoassays. The recovery studies showed that for amphetamine, Δ9THC, cocaine, methadone, methamphetamine, morphine and temazepam over 90% of the drug in the sample was eluted from the collector. The Cozart® DDS oral fluid collector provides a reliable mechanism for the collection of oral fluid at the roadside that achieves the rapid collection times required. 相似文献

曾朴不仅是晚清知名小说家,也是近现代文学史上一位重要的文学翻译家。1912年辛亥革命后,曾朴从法语翻译了雨果的名作《九十三年》,并将其题为“法国革命外史”,刊载于《时报》。曾朴于此时翻译《九十三年》,虽然明显地包含着应合中国革命时局的动机,但作品高扬人性的主题却超越了单纯的政治革命,表达了“诗人”的革命理想。译者曾朴的“诗人”身份以及他对作品的细致解读又使他进一步阐发了作品“不失其赤子之心”的人道主题,因此使这部小说在当时显示出一种“不合时宜”的思考革命的理路。 相似文献

Although restorative justice principles and practice have been applied extensively in community‐based juvenile justice settings, implementation in residential treatment facilities has been far less common. We describe recent experimentation and possibilities for broader application to disciplinary infractions, the response to harm and crime, promoting community and citizen input, “community building” for conflict resolution skill development and changing the culture of facilities, and reentry. We conceptualize three “communities” as most relevant to addressing needs of incarcerated youths, their victims, and support groups, and then discuss theoretical frameworks and empirical research supportive of restorative practice in this context. Challenges to implementation of restorative practice, compatibility with other treatment and disciplinary agendas, and concerns about preserving the integrity of the model are also considered. 相似文献

Bites of Trombiculid mites implicated a suspect during a homicide investigation. Clinical documentation of the bites, correlation with entomological studies, and submission of evidence at trial are reported. Insects that have a discrete geographic distribution and leave bites of a characteristic nature may have important forensic science implications. 相似文献

Graduate programs in public policy offer a variety of ethics courses focusing on framework theories, topical applications, and duties of office. Brown gives four reasons for making these types of courses an integral part of education for public service: they provide a common civic vocabulary; they give an essential perspective on analytical techniques; they challenge students' own presuppositions about public policy; and they help distinguish between empirical and conceptual issues. He argues that the growing emphasis in the policy programs on public management further enhances the importance of education in ethics, and that the current dearth of such courses in some programs seriously impedes their graduates. 相似文献
