In view of the MENA increasing participation in multinational trials and the increasing number of national/regional trials, this article explores potential areas of pharmacovigilance, requiring reform and provides recommendations for building a robust safety reporting system. Regulatory silence on expedited reporting requirements creates confusion for local sites that are part of multinational trials. Not allowing waiver for serious adverse events that are protocol specified or are study endpoints, along with lack of emphasis on causality as reporting criteria, adds substantial burden of uninformative cases for regulatory review. Despite global focus on Development Safety Update Report, local regulators are not yet insistent on real-time update of a drug’s cumulative safety profile. Issues like reporting requirements for generic trials, pregnancy reporting and lenient timeline for death/life-threatening events need attention. Finally, the need to formulate an all-encompassing local pharmacovigilance guideline, in sync with global practice cannot be overemphasized.  相似文献

Survey measures of self-control provide a potential low-cost alternative to incentivized elicitation. However, asking respondents to introspect on their self-control problems may instead measure their awareness of them, especially in populations with low self-control. We illustrate this with the Ameriks, Caplin, Leahy, and Tyler (2007) survey, which captures self-control problems through the deviation between self-reported ideal and predicted behavior (Expected Deviation, ED). Previous empirical evidence from high income or highly educated populations correlates larger ED with worse outcomes. We theoretically show that the reverse will be true in settings where awareness can play a large role: when self-control is low and costly commitment devices are available. We empirically show that, for residents of a homeless shelter, ED is positively correlated to savings in shelter lockboxes, a costly commitment device. This correlation is stronger for those likely to experience more self-control problems: individuals with past addiction problems.  相似文献

This paper reports the results of a cross-national study spanning England, New Zealand and the United States. A total of 496 first year undergraduates studying business or social science completed a 20-item questionnaire. This focused on their attitudes to their debt incurred while studying, as measured on a five-point Likert scale. A factor analysis model was developed, from which four consistent factors emerged, explaining 45 percent of the variation and consistent between countries. These factors were named: Anxiety, Utility-For-Lifestyle, Utility-For-Investment and Awareness. The first three factors were found to be uncorrelated with each other, but higher Awareness was associated with lower levels of Anxiety and Utility-For-Lifestyle and higher levels of Utility-For-Investment. The relationship with previous studies and implications for theory and practice are discussed.  相似文献

作为一种典型的非财报信息,战略合作信息具有独特的价值,正受到资本市场越来越多的关注。以2007—2018年上市公司战略合作协议公告作为研究对象,采用人工评分法和文本分析法全面评价了战略合作信息披露质量,并探讨了信息披露质量、信息披露“言行一致”的“短期”市场反应及其对经营业绩的影响。研究发现,资本市场对战略合作信息披露持积极反应,即战略合作信息披露质量越高,信息披露窗口期股票超额累计收益率越高。同时,战略合作信息披露质量越高,战略合作越容易落地,即信息披露的“言行一致”性越强;公司治理水平的提高有助于强化上述“正向反馈”。此外,战略合作信息披露的“言行一致”性越强,上市公司超额累计收益率越高,经营业绩越好。但在民营企业中仅表现出超额累计收益率的提高,在国有企业中仅表现出经营业绩的提升。因此,战略合作信息的准确披露有助于利益相关者深刻理解上市公司的战略规划,对公司经营大有帮助,监管部门应加强对此类信息的披露要求和规范审核。  相似文献

This research examines the neurophysiological correlates of consumers’ price memory processes. We focus on the explicit and implicit dimensions of consumers’ price knowledge and use an experimental functional Magnetic Resonance Imaging (fMRI) study to assess how the encoding of task-dependent price memory affects the choice process and neural activation. The findings of our study add to the field of consumer neuroscience by demonstrating how neural correlates of explicit and implicit task-dependent price memory can shed light on processes that guide consumer decision-making. Over the course of our experiment we found that consumers did not always make consistent decisions, but that their decisions were influenced by explicit components of price memory. Implicit price memory components seem to have a more supportive role in the decision-making process. In summary, we found that price memory is a dynamic construct that is influenced by unconscious and neurophysiological processes, and we conclude that a neurophysiological perspective can add value for consumer and marketing research.  相似文献

Many of the procedures undertaken within healthcare require specialized forms of participation that may be unfamiliar, even disturbing, to patients or clients. The practitioner has to encourage and enable participation in the investigation in an appropriate fashion while preserving the structure and integrity of the procedure. In this article, we consider optometry and the deployment of a vision test, known as subject refraction, that provides data to help determine the characteristics of any corrective lens that may be required by clients. The procedure's ability to establish robust and reliable data relies upon the optometrist's ability to encourage the client to respond to a series of stimuli without consideration or reflection. That is, the client is required to produce an unwitting response—conduct that might be considered nonsymbolic rather than symbolic. In this article, we also consider the optometrist's talk and bodily comportment during subjective refraction and how it serves to shape and determine the quality of the client's response and participation, and in turn to produce reliable test results.  相似文献

We investigated two aspects of credit card repayment decisions: the extent to which the anchoring effect of minimum repayment information may be mitigated by information on alternative anchors, specifically repayments that would repay the balance in two years (Study 1) or nine months (Study 2); and the role of future repayment concern. In two experiments, three realistic credit card statements were presented with different outstanding balances. Participants, who were randomly allocated to one of four information conditions depending on supplementary information provided on the statements, stated how much they would repay that month. They were then asked about concerns they would have about repayment difficulties if they had a fixed consumer loan over three years. In Study 1 the alternative two-year repayment anchor had a negative effect on percent repayment, whereas in Study 2 the nine-month repayment anchor had a significant positive effect, especially for those with higher future repayment concern. Also, in both studies, future repayment concern had a direct inverse effect on repayment decisions which partially mediated the effect of disposable income. It is concluded that the addition to credit card statements of a table of cost and duration information for a range of repayment amounts may usefully support repayment decisions.  相似文献

Summary

Over the past 10 years, a Japanese cooperative association named Fukushi Club Seikyo (FCS) has developed a unique, non-profit business specializing in services for the elderly. It aims to promote a reciprocal support system among neighborhood community members. FCS has successively organized its active members, mainly homemakers, into workers' collectives and successfully provided various life support services at a very small charge. Their human-touch service appears in sharp contrast to bureaucratic public services and profit-making private services. The civil initiative presented by FCS suggests a potential for a community-based social service system that may guarantee quality services without raising taxes and premiums for social insurance.  相似文献
