Online review helpfulness ratings are an important indicator of the impact of online reviews. Often times, helpfulness is explained in terms of observable qualities of online reviews that predict helpfulness ratings. This research proposes that focusing on the psychological processes that underlie helpfulness voting informs a better understanding of what shapes review helpfulness ratings. Specifically, because goal orientation influences information processing, consumers’ regulatory orientation interacts with review valence to determine review helpfulness. When review valence and regulatory orientation match, consumers are more likely to express helpfulness through voting. The findings show that this effect occurs at least in part because matching review valence and regulatory orientation instills feelings of gratitude towards the reviewer. As a consequence, consumers are more likely to reward the reviewer with a helpfulness vote to express their feeling of gratitude through actions. However, when reviewers actively state expectations of reciprocal behavior by readers, gratitude is reduced and so is the likelihood that a review receives a helpfulness vote. Evidence from five studies using review data and online experiments show support for these effects.  相似文献

E-commerce sites have been doing profitable business since their induction in high-speed and secured networks. Moreover, they continue to influence consumers through various methods. One of the most effective methods is the e-commerce review rating system, in which consumers provide review ratings for the products used. However, almost all e-commerce review rating systems are unable to provide cumulative review ratings. Furthermore, review ratings are influenced by positive and negative malicious feedback ratings, collectively called false reviews. In this paper, we proposed an e-commerce review system framework developed using the cumulative sum method to detect and remove malicious review ratings.  相似文献

Peer review of teaching (PRoT) is recommended to both develop and assure the quality of teaching practices in Higher Education. An institutional implementation of a peer review process can be viewed as a genuine desire to improve teaching quality or as an instrument of accountability and performativity. There are many approaches to the peer review of teaching operating. This article documents the impact, advantages and disadvantages of direct participation in three peer review of teaching processes.  相似文献

The prevalence of post-traumatic stress disorder (PTSD) continues to increase. Symptomology of PTSD include sensory deficits much like those displayed in children with sensory integration (SI) disorder. The aim of this scoping review is to review symptoms of PTSD and SI, and make a case of how aquatic therapy may be an effective modality in treating clients with PTSD. Eighteen articles were selected for review. From this review, it is suggested that aquatic therapy can be an effective modality in reducing symptoms of PTSD; however, future research is essential in determining its effectiveness.  相似文献

The review system on research with human participants in the Netherlands is characterised as a decentralised controlled and integrated peer review system. It consists of an independent governmental body, the Central Committee on Research Involving Human Subjects (or Central Committee), which regulates the review of research proposals by accredited Medical Research Ethics Committees (MRECs). The legal basis was founded in 1999 with the Medical Research Involving Human Subjects Act. The review system is a decentralised arrangement since most research proposal are reviewed by the 30 accredited MRECs in the country. It is a controlled system in which the Central Committee is responsible for the accreditation and oversight of the MRECs and can make legally binding directives for these committees. The assessment of research proposals is an integrated peer review process in which all documents of the research file are reviewed by experts in one committee only. A small number of research proposals are assessed by the Central Committee and not by accredited MRECs. These proposals are on specific research categories such as gene therapy, cell therapy and embryo research. The review of research with surplus human embryos is regulated separately in the Embryos Act. The Central Committee provides support to the accredited MRECs and to researchers and sponsors. It is currently developing an internet portal to reduce the bureaucracy and make the review process more efficient and transparent. The Central Committee stimulates confidence on medical research in society by providing a public trial registry with core data on reviewed research proposals.  相似文献

This review looks at the relationship between attention and language. There have been many studies that have shown a certain role of attention on sentence and spoken word processing. At the same time some other studies have observed that language processing is autonomous. In this review an attempt has been made to review the empirical evidence from sentence processing in reading, auditory processing and speaking domains to see if attentional manipulations cause interference with processing. The review suggests currently available evidence is rather mixed and it is still a long way to fully explore the attentional basis of sentence processing.  相似文献

It is not unusual for researchers to complain about institutional review board (IRB) oversight, but social scientists have a unique set of objections to the work of ethics committees. In an effort to better understand the problems associated with ethics review of social, behavioral, and economic sciences (SBES) research, this article examinees 3 different aspects of research ethics committees: (a) the composition of review boards; (b) the guidelines used by these boards to review SBES--and in particular, behavioral health--research; and (c) the actual deliberations of IRBs. The article concludes with recommendations for changes in the review process and with suggestions for filling the gaps in knowledge about the way IRBs work.  相似文献

The peer review process, whether formally applied in publication and grant review, or informally, such as exchange of ideas in scientific and professional newsgroups, has sparked controversy. Writers in this area agree that scholarly reviews that are inappropriate in tone are not uncommon. Indeed, commentators have suggested rules and guidelines that can be used to improve the review process and to make reviewers more accountable. In this paper, we examine the relevance and impact of ethical codes on the conduct of peer review. It is our contention that the peer review process can be improved, not by a new set of rules but through closer attention to the ethical principles to which we, as psychologists, already subscribe.  相似文献

The model of moral reasoning used in Institutional Review Board review fails to uphold ethical ideals for research participants for it does not adequately acknowledge the particular context of research or of subjects, including their gender, their socioeconomic status, and the communities in which they lead their lives. The ethical review of research needs to take seriously the particularities of the research context as well as the situations of potential participants. A variety of conclusions are drawn for changes to the system for ethical review. Most significant is a call for effective consultation with the various communities affected by research and greater reliance on subject representatives. Also proposed is national review for selected research.  相似文献

Architectural design review is a method of environmental management which is widely used by governmental agencies in both the United States and in Great Britain. Because design review is a governmental function, there is a major need to assess how well it works. Research covering over 29,000 respondents and 5,600 environmental scenes suggests that scientific protocols can be adapted to provide an accurate and efficient design review protocol. The protocol uses preference experiments to find the standardized mean difference [formula: see text] between a proposed project and a random sample of existing projects. Values of d will indicate whether the project will increase, maintain, or diminish the aesthetic merit of the sampled area. The protocol is illustrated by applying it to the case of design review for a single residence. Implications for further implementations are discussed.  相似文献

A review of the literature and ethnographic data from Australia, Canada, New Zealand, the United States, and the United Kingdom on the research ethics review process suggest that moral panics can become triggers for punctuated equilibrium in the review process at both the macro and microlevel, albeit with significantly different levels of magnitude and impact. These data suggest that neither the development of the ethics review process nor the process itself proceeds gradually, but both are characterized by periodic major shifts evoked by particular events or situations that result in varying levels of moral panic. One way to deal with this moral panic is to increase the regulation of research and the depth or intensity of the scrutiny of applications under ethics review. Moral panics at the macrolevel influence those at the microlevel and, if the moral panic evoked at the local or microlevel is not satisfactorily resolved, it will evoke action at a higher level. Understanding the evolution of research ethics review processes from this perspective might help make actions by ethics committees and policy makers more understandable and help explain why attention to research ethics are heightened at particular points in time. It may also provide a basis for developing recommendations for adaptations to the ethics review process and policy at both the local and macrolevel.  相似文献

Counselling in primary care in the UK is expanding rapidly, and its evidence base needs to be established. We present the rationale for conducting controlled trials of counselling in primary care, and suggest that a systematic review of controlled trials of counselling in primary care is timely. We describe the process of conducting the review in accordance with Cochrane Collaboration guidelines. The review aimed to assess the effectiveness and cost-effectiveness of counselling in primary care, by systematically reviewing cost and outcome data from randomised controlled trials and controlled patient preference trials of counselling interventions, for patients with psychological and psychosocial problems considered suitable for counselling. The search strategy, inclusion and exclusion criteria, data collection and data analysis are described. The results of the review are presented. The review included only controlled trials of counselling in which counsellors accredited by the British Association for Counselling (or equivalent) provided non-directive counselling in primary care. Four trials met the inclusion criteria. Results indicated that patients who receive counselling show a modest but significant improvement in symptom levels compared with those who receive GP care. Levels of satisfaction with counselling are high. There is very tentative evidence to suggest that counselled patients are more likely to be considered recovered than usual GP care patients. There is limited information about the cost-effectiveness of counselling. We conclude by reflecting upon the results of the review and their implications for counselling research.  相似文献

A review of the effects of noise on human performance   总被引:4,自引:0,他引:4  
The present review is concerned with the effects of noise, especially moderate intensity noise on performance. The review covers recent empirical results and theoretical approaches, and examines the importance of the nature of the noise, individual differences in response to noise, and other factors which modify the effects of noise. A central theme of the review is that it is essential to consider the nature of the task being performed in noise, and a profile of strategies of performance in noise is presented. Finally, recommendations are made about the direction and methodology of future research.  相似文献
