A problem for achieving informed choice

Most agree that, if all else is equal, patients should be provided with enough information about proposed medical therapies to allow them to make an informed decision about what, if anything, they wish to receive. This is the principle of informed choice; it is closely related to the notion of informed consent. Contemporary clinical trials are analysed according to classical statistics. This paper puts forward the argument that classical statistics does not provide the right sort of information for informing choice. The notion of probability used by classical statistics is complex and difficult to communicate. Therapeutic decisions are best informed by statistical approaches that assign probabilities to hypotheses about the benefits and harms of therapies. Bayesian approaches to statistical inference provide such probabilities.

Marketing Research Ethics: Researcher’s Obligations toward Human Subjects

This paper addresses the growing concern over violation of research ethics in marketing, in particular rights of human subjects in fieldwork, notably the right to informed consent; right to privacy and confidentiality; and right not to be deceived or harmed as a result of participation in a research. The paper highlights the interaction of the three main parties involved in most marketing research: the sponsoring organization (client or user), researcher, and participant in the survey, focusing on researcher’s ethical responsibilities in interacting with human subjects in surveys. The paper stresses the importance of ethical integrity in marketing research and emphasizes the need to establish a universal model for regulatory requirements and well institutionalized practice of ethical research.     

情色文字与图片对大学生性倾向印象形成的启动差异

128名大学生被平均分成四个组,分别接受情色文字刺激、非情色文字刺激、情色图片刺激与非情色图片刺激,考察不同材料的情色信息会对性倾向印象形成产生怎样的启动效应。结果表明:情色文字对性倾向印象形成产生显著的正向启动效应,而情色图片对性倾向印象形成的启动没有呈现出单一方向的显著效应;男性对他人的性倾向印象形成要显著高于女性,但性别因素不对启动效应产生中介影响;接触容易令人产生性联想的情色刺激会导致个体更倾向于以性的或情色的眼光看待他人。

Effects of different substance misuse in genital reflexes of paradoxical sleep deprived male rats

As psychostimulants are widely abused, their neurochemical and behavioral effects have been extensively studied for many years. Our previous data demonstrate that paradoxical sleep deprivation (PSD) enhances drug-induced penile erection and ejaculation. PSD in association to drugs of abuse like cocaine potentiated genital reflexes in male rats. In this sense, the present study investigated if three substances abused by young people--such as Delta(9)-tetrahydrocannabinol (Delta(9)THC), alcohol and caffeine--had any significant effect on the genital reflexes in PSD rats. The results indicated that PSD induced erection in 50% of the rats and 20% ejaculated. In addition, there was no significant alteration in the number of animals exhibiting genital reflexes neither on the frequency of these behaviors when challenged with Delta(9)-THC or alcohol or caffeine after 96 h of PSD. These findings show that Delta(9)THC, alcohol and caffeine when administrated isolated did not produce alterations in genital reflexes in the PSD male rats.     

Adolescent motherhood: a Q‐methodological re‐evaluation of psychological and social outcomes

Traditionally, adolescent motherhood has been associated with numerous negative social, psychological and societal outcomes. However, in recent years there has been a gradual acceptance that there are many positive features to adolescent motherhood, but methodological issues have been identified within the field. This study aimed to examine adolescent motherhood from the mothers' own perspectives, exploring their attitudes towards the issues that they described as being important in their lives, by using Q‐methodology in an attempt to counter some of these methodological limitations. The mothers within the study appeared to be coping positively in their role in that levels of symptomatology, as determined from questionnaire assessment, appeared to be relatively low and they indicated through Q‐sort analysis that motherhood had been beneficial to their lives. Three independent factors (clusters of attitudes) were identified within the sample (N = 23) which differed over the dimensions of: employment, social support, coping, partner co‐habitation, financial support, maternal role satisfaction, aspirations for the future, as well as the nature of the relationship with their child(ren)'s father and their satisfaction with the fathers' role. The significance of these findings with regard to educational and social services is discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

保护动机对农村流动人口性病艾滋病高危性行为的预测

农村流动人口已经成为我国性病艾滋病预防干预的重点人群。为了探讨流动人口所存在的性病艾滋病高危性行为,以及保护动机（Protection Motivation）对性病艾滋病高危性行为的预测作用,研究选取2201名从农村到北京打工已有3个月的流动人口为被试,采用问卷调查的形式,要求其报自己报告初始性行为发生的时间、性伙伴的数量、商业性行为、性伙伴的性行为、安全套的使用,对我国性病艾滋病严重程度的评估,以及所拥有的性病艾滋病症状知识和传播知识。对904名已发生性行为的流动人口的统计分析发现：（1）农村流动人口存在较多的高危性行为,男性流动人口的高危性行为明显多于女性流动人口;（2）保护动机理论对农村流动人口的性病艾滋病高危性行为具有明显的预测作用,其中的外在奖励、内在奖励、反应效能和反应代价与农村流动人口的性病艾滋病高危性行为的关系更为密切。研究揭示,保护动机理论可以作为我国今后开展农村流动人口性病艾滋病高危性行为预防干预工作的一个基础
