On epistemic and moral certainty: A wittgensteinian approach

Abstract

Epistemic and moral certainities like ‘This is a hand’ or ‘Killing people is evil’ will be interpreted as constitutive rules of language games, such that they are unjustifiable, undeniable and serving as obliging standards of truth, goodness and rationality for members of a community engaging in the respective practices.     

Decisions to donate bone marrow: The role of attitudes and subjective norms across cultures

Abstract

This paper reports the results of a field investigation of the determinants of decisions to donate bone marrow. Predictions are made on the basis of a modification of the theory of reasoned action wherein attitudes are operational-ized in separate affective and evaluative components. Boundary conditions of the theory of reasoned action are further explored by examining the effects of culture (Hong Kong Chinese, N= 190; American Chinese, N = 107; black Americans, N = 124; and white Americans N = 122) on decisions to donate for each of four targets: Immediate Family Members (TFM), Close Relatives (CR), Ethnic Strangers (ES), and Total Strangers (TS). For this life or death decision, the willingness to give is hypothesized to vary as a function of the so-called fitness value of the recipients (i.e., their capacity to contribute to the donor's inclusive fitness), as modified by cultural differences between group- versus independent-based cultures. Among other results, the following gradient was found in attitudes, subjective norms, and intentions for Chinese: IFM > CR > ES > TS; for Americans the pattern was IFM = CR > ES = TS. American Chinese showed stronger attitudes and felt norms, but not intentions, to give to close relatives than did Hong Kong Chinese, reflecting differential in-group/out-group pressures. Black and White Americans showed stronger attitudes, subjective norms, and intentions to donate to strangers than did Chinese.     

Predicting intended contraception in a sample of ethiopian female adolescents: The validity of the theory of planned behavior

Abstract

The purposes of the study were threefold. First, to test the validity of Ajzen's (1991) theory of planned behavior (TPB) in predicting intended contraception in the Ethiopian cultural setting. Second, to examine the additional predictive roles of past behavior and perceived pregnancy risk in the TPB model. Third, to identify the salient contraceptive beliefs influencing intended contraception. Data stemmed from a community sample of 354 sexually active female adolescents aged 15 to 19 years. The findings of the study supported TPB as a robust model in Ethiopian cultural setting, with subjective norm being the strongest predictor of intended contraception. In addition, both past contraceptive behavior and perceived pregnancy risk demonstrated to have significant contributions in predicting intention over and above that explained by attitude, subjective norm and perceived behavioral control elements of the TPB. Moreover, the study also identified salient and important contraceptive beliefs that need to be addressed in family life education and counseling programs designed for adolescents and the youth.     

Young adults' intention to eat healthy food: Extending the theory of planned behaviour

Abstract

The present study predicts adults' intention to eat healthily, using the theory of planned behaviour (TPB) and additive and moderating effects of role identity, group norms and group identification, derived from identity theory and self categorisation theory. A total of 735, 25 years old adults participated in a mailed questionnaire survey in 1997. The TPB explained 52% of the variance in young adults' decision to eat healthily, with perceived behavioural control and subjective norms being the strongest (β= .56, p < .001) and weakest (β = .05, p < .005) determinants, respectively. Although, role identity accounted for an additional amount of 4% of the variance in behavioral intention, past behaviour did not moderate the impact of role identity on intention, as hypothesised. Neither perceived group norm nor group identification added to the prediction of intention over and above the TPB. However, group identification was found to act as a moderator on the relation between group norm and behavioural intention in the predicted direction. The wider social context seems to play a stronger role for the formation of adults' healthy eating decisions than indicated by the TPB.     

Precision Weapons,Civilian Casualties,and Support for the Use of Force

Precision weapons such as drones have become important elements of the military strategies of the United States and other countries. How does the use of precision weapons influence public support for the use of force? The public is averse to casualties, mission failure, and collateral damage. I argue that precision weapons increase the salience and importance of avoiding civilian harm. Individuals adopt their expectations about the outcomes of using these weapons and have lower tolerance for attacks that result in civilian deaths. This proposition is consistent with the results of two survey experiments. In the first, the possibility of civilian casualties leads to larger declines in support for the use of force than do military casualties or mission failure. In the second, respondents primed with information about an attack with precision weapons exhibited less tolerance for civilian harm than those primed with other weapons systems, despite the fact that the outcomes described to all respondents were identical.     

Women want taller men more than men want shorter women

Physical characteristics, such as height, play an important role in human mate preferences. Satisfaction with one’s own height and one’s partner height seem likely to be related to these preferences. Using a student sample (N = 650), we show that women are not only more selective, but also more consistent, than men, in their partner height preferences. Women prefer, on average, a larger height difference between themselves and their partner (i.e. males being much taller than themselves) than men do. This effect is even more pronounced when examining satisfaction with actual partner height: women are most satisfied when their partner was 21 cm taller, whereas men are most satisfied when they were 8 cm taller than their partner. Next, using data from our sample and that of a previously published study (N = 52,677), we show that for men, height is more important to the expression of satisfaction with one’s own height than it is for women. Furthermore, slightly above average height women and tall men are most satisfied with their heights. We conclude that satisfaction with one’s own height is at least partly a consequence of the height preference of the opposite sex and satisfaction with one’s partner height.

Bystanders' reactions towards co‐punishment events in the Taiwanese military: Examining the moderating effects of organizational norms

The present study examined bystanders' justice perceptions about co‐punishment events. In a sample of 169 logistic officers in the Taiwanese military, responsibility attributions (i.e. liability attributed to co‐punished persons) had a negative relationship with perceived harshness, and a positive relationship with perceived procedural justice. In addition, the effects of responsibility attributions on procedural justice were weaker if the person perceived stronger rather than weaker organizational norms of co‐punishment.     

中国人人格形容词评定量表(QZPAS)的信度、效度与常模

本研究的目的是建立中国人人格形容词评定量表(QZPAS)的信度、效度和常模。4000多名被试对由123个形容词组成的QZPAS的评定结果支持了中国人人格的“大七”模型,各因素有着良好的内部一致性和重测信度。自-他评定的相关以及自我总体评定与量表分数间的相关表明QZPAS有良好的效标效度。本研究所提供的常模也为该量表的应用提供了基础。
