1. Consumers who elect to use natural products are electing to do more than simply use a product. Their choice is an act of self-empowerment. 2. Education is necessary because these products most often are not being obtained in a professional, consultative setting but rather in chain discount department stores and supermarkets. 3. If consumers choose to address their health concerns using a natural-based treatment plan, consultation with a health care practitioner who shares this shift in perspective and who follows the literature is important. 4. A paradigm shift could be on the health care horizon, which when complete would make herbs and other natural products part of mainstream health care practice. 相似文献

In this case study, we describe the symptoms, neurological examination, test results, and brain pathology of a man with Parkinson's disease (PD). PD commonly presents with tremor or changes in one's ability to walk or move. Other major difficulties caused by this disease include rigidity of the body, slowness of movement, and postural imbalance. The disease symptoms principally result from the degeneration of a specific population of neuronal cells in the brain stem, in a region called the pars compacta of the substantia nigra. Pathology shows the loss of these cells and the appearance of characteristic neuronal cytoplasmic inclusions called Lewy bodies, which are composed principally of aggregated alpha-synuclein protein. 相似文献

This ethnography focuses on the techniques of normalization used by university professors who are accused by their colleagues of bullying behavior. We examine how the organizational structure and institutional values of the university provide protective coloration for academic intimidation and discourage both the detection and effective labeling of such behavior. In noting that attempts to label bullying behavior frequently fail because the judgments are seen as mere matters of opinion in an environment whose principal currency of exchange is opinion itself, we modify and extend Sykes and Matza's discussion of neutralization techniques to academic settings. While we cannot speak to the presence or absence of guilt feelings on the part of alleged academic bullies, or to whether neutralization techniques successfully assuage such feelings, we can nevertheless discern the operation of these techniques to resist the imputation of unflattering social identities and/or to lay claim to public identities that are highly esteemed within the academy. Moreover, we identify three additional techniques of normalization that are employed by alleged ivory tower bullies: appropriation and inversion, in which accused bullies claim victim status for themselves; evidentiary solipsism, in which alleged bullies portray themselves as uniquely capable of divining and defining the true meaning-structure of events; and emotional obfuscation, which takes the form of employing symbols and imagery that are chosen for their perceived ability to elicit an emotional response on the part of an academic audience. 相似文献

When contract research organizations (CROs) were first formed, pharmaceutical companies outsourced to them only certain aspects of the conduct of their clinical trials. At first CROs were highly specialized entities, providing, for example, either biostatistical advice, clinical research associates who monitored investigational sites for regulatory compliance, or regulatory support. Gradually, full service CROs emerged, offering a full range of services for clinical trials, including the selection of investigators and investigational sites, assistance with patient recruitment, safety surveillance and reporting, site audits, and data management and biostatistics. This evolving relationship between CROs and the pharmaceutical and medical device industries has resulted in CROs assuming more and more of the regulatory and ethical risks and responsibilities inherent in the conduct of clinical trials. In this full service role, CROs, unlike sponsors, are not interested in the outcome of study, but like sponsors, are subject to heavy regulation by the federal government, must follow applicable state laws, must respect international guidelines, and are obliged to follow their own operating procedures. Moreover, they are judged by the industry on the basis of the scope and quality of services provided, including the degree of adherence to the research protocol, regulatory requirements, and timelines; the quality of the professional working relationships with investigators and institutions, both academic and community-based; and the validity of the data. Further, CROs are subject to comprehensive audits by sponsoring companies, FDA, and other regulatory authorities. For all these reasons, CROs are being tasked with strict vigilance of all stages of the clinical trial process to ensure that the laws, regulations, and industry standards designed for the protection of human subjects and data integrity are maintained. 相似文献

Researchers and institutional review boards are routinely called upon to evaluate the cost-benefit status of proposed research protocols that involve human participants. Often these assessments are based on subjective judgments in the absence of empirical data. This reliance on subjective judgments is of particular concern for studies involving clinical samples where unfounded assumptions may adversely affect research progress or clinical outcomes. The Reactions to Research Participation Questionnaire (RRPQ) was designed to address this shortcoming and to help promote ethical decision making about research practice. The present study describes development of the RRPQ and presents a series of exploratory and confirmatory analyses investigating its structure. Based on these findings, a revised version of the instrument and suggestions for future research are presented. This approach provides a foundation for scientifically informed protection of human subjects. 相似文献
