The current decision-making model for the review of human research contains inadequate mechanisms to ensure that the interests and perspectives of research participants are considered by Institutional Review Boards, whose decisions may profoundly affect the safety and well-being of participants. As a result, this model is far from being optimized to realize Institutional Review Boards' principal mandate and undermines the credibility of the research review process. This article proposes a procedural mechanism that would ameliorate these systemic deficiencies by allowing “research participant representatives” to give voice to participants during the research review process. 相似文献

Ethical dilemmas are inherently ambiguous, complex, and ill-defined. Additionally, these dilemmas involve multiple stakeholders. These characteristics may induce political behavior as a resolution tactic. Thus, the goal of the present effort was to investigate perspectives on politics among researchers in an ethical decision-making context. A qualitative analysis of interviews with university faculty members revealed that faculty members’ perspectives on political behavior in an ethical decision-making context fall into a number of categories, including positive, negative, and realistic views of political activity. The implications of these varying perspectives on ethical decision making are discussed. 相似文献

A Comparison of Address-Based Sampling (ABS) Versus Random-Digit Dialing (RDD) for General Population Surveys 总被引:1,自引:0,他引:1

Valid and reliable public health data are becoming more difficultto obtain through random-digit dial (RDD) telephone surveys.As a result, researchers are evaluating different survey designs(i.e., sampling frame and survey mode combinations) as complementsor alternatives to RDD. Traditionally, mail surveys of the generalpublic have been limited due to a lack of a complete samplingframe of households. Recent advances in electronic record keeping,however, have allowed researchers to develop a sample from aframe of addresses (e.g., the U.S. Postal Service Delivery SequenceFile, which appears to provide coverage which rivals or possiblyexceeds that obtained through RDD sampling methods). To testthe use of this frame for surveying adults aged 18 years andolder across a wide geographic area, a pilot study was conductedas part of the 2005 Behavioral Risk Factor Surveillance System(BRFSS). The pilot compared use of a traditional, RDD telephonesurvey methodology to an approach using a mail version of thequestionnaire completed by a random sample of households drawnfrom an address-based frame. The findings indicate that themail survey approach can achieve higher response rates in low-response-ratestates (<40%) than RDD (particularly when two mailings aresent). Additionally, the address frame with mail survey designprovides access to cell phone only households and offers costsavings over the telephone approach. The resulting sample, however,significantly overrepresents non-Hispanic whites and peoplewith higher levels of education. 相似文献

This study examined gender differences and preferences in the use of and response to six different styles of condom use negotiation with a hypothetical sexual partner of the opposite gender. Participants were 51 heterosexually active African American adults attending an inner-city community center. Participants completed a semistructured qualitative interview in which they were presented with six negotiation strategies based on Raven's 1992 Power/Interaction Model of Interpersonal Influence. Results showed that female participants responded best to referent, reward, and legitimate strategies, and worst to informational tactics. Male participants responded best to reward strategies, and worst to coercion to use condoms. Further, responses given by a subset of participants indicated that use of negotiation tactics involving coercion to use condoms may result in negative or angry reactions. Response to strategies may vary with the value of the relationship as viewed by the target of negotiation. Implications for HIV prevention efforts are discussed. 相似文献

Recent analyses of protest policing in Western democracies argue that there has been a marked shift away from oppressive or coercive approaches to an emphasis on consensus based negotiation. King and Waddington (2005) amongst others, however, suggest that the policing of international summits may be an exception to this rule. This paper examines protest policing in relation to the 2005 G8 summit in Gleneagles, Scotland. We argue that 'negotiated management' cannot be imported wholesale as a policing strategy. Rather it is mediated by local history, forms of police knowledge and modes of engagement. Drawing on interviews and participant observation we show that 'negotiated management' works best when both sides are committed to negotiation and that police stereotyping or protestor intransigence can lead to the escalation of any given event. In closing we note the new challenges posed by forms of 'global' protest and consider the implications for future policing of protest. 相似文献

Excitement-seeking and related constructs have been associated with heavier gambling and negative health measures in problem
and/or pathological gamblers. Most adults gamble recreationally and an understanding of the relationship between excitement-seeking
as a motivation for gambling amongst subsyndromal gamblers has significant public health implications. Logistic regression
analyses were used to examine a national sample of past-year recreational gamblers (N = 1,476) to identify characteristics distinguishing gamblers acknowledging gambling for excitement (“Excitement-seeking Gamblers”
or EGs) and gamblers denying gambling for excitement (“Non-excitement-seeking Gamblers” or NEGs). EGs were more likely than
NEGs to report alcohol use and abuse/dependence, any substance abuse/dependence, incarceration, large gambling wins and losses,
more frequent and varied gambling, and symptoms of pathological gambling (i.e., at-risk gambling). Together, these findings
indicate that EGs are more likely than NEGs to demonstrate problems in multiple areas characterized by impaired impulse control. 相似文献

Recent empirical studies have evaluated if modifying electronic gambling machine (EGM) structural features could encourage
safer gambling behaviors and decrease gambling-related problems. Several of these studies refer to Harm Reduction (HR), suggesting
that the HR paradigm is useful to design, implement and test the efficacy of various prevention and treatment programs applied
to EGM users. After reviewing the origins of HR and specifying its operational definition, this paper discusses the relevance
of the HR framework for the study of measures related to EGM use and gambling in general. Examples are given to illustrate
the arguments. The results show that HR has been over-inclusive in the field of gambling. A specific and operational definition
and application of the HR framework is required for HR to be useful for the advancement of research in the gambling field.

Although there has been much speculation about the possible links between gambling and crime rates, relevant quantitative
evidence has been practically non-existent in Australia to date. This paper reports the results of research that utilised
a model designed to investigate the potential relationship between electronic gaming machine expenditures and property (income-generating)
crime rates reported to police in local areas in South Australia in 2002–2003. The research found that the higher the expenditures
on gaming machines in a particular local area per adult, the higher the income-generating crime rate in that area. No such
relationship was found between gaming machine expenditure and non-income-generating crime rates. However, further research
is required before any policy-relevant conclusions can be drawn. 相似文献

This study aims to develop a greater understanding of age differences in savings outcomes within Individual Development Accounts (IDAs). Participant data from the American Dream Demonstration (ADD) are examined for age differences in accumulated net deposits, average monthly net deposits, and deposit frequency. ADDprogram data are examined for savings match rates, monthly savings targets, direct deposit, and hours of financial education offered. Results indicate that, on average, older IDA participants have better savings outcomes than younger participants. Findings from this study suggest that impoverished middleaged and older adults can save if provided an opportunity and incentives. However, success will depend on the characteristics of the programs. 相似文献

Just as there is no universal understanding of what constitutes Coaching, there are no generally accepted ethical standards within Coaching. Opinions as to ethics within Coaching spring largely from the various ??Schools?? which transmit Coaching methods. Coaches working with J. L. Moreno??s Psychodrama follow the ethical and philosophical outlook contained in the analysis of creativity, spontaneity, the ??Social Atom?? and in the method, process orientated ??Encounter?? as understood by Moreno and Buber. That which they have internalised as ethical maxim and the Encounter method, is also understood to be a fundamental intervention. 相似文献
