Reliability and concurrent validation of the IPIP Big-Five factor markers in China: Consistencies in factor structure between Internet-obtained heterosexual and homosexual samples

Previous studies have suggested the cross-cultural generalizability of a 5-factor structure for personality traits. In this article, we analyzed the utility of 2 versions (100-item and 50-item) of the IPIP Big-Five factor markers in both heterosexual (N = 633) and homosexual (N = 437) samples in China. Factor analysis within versions showed that both versions of these IPIP measures showed clear 5-factor orthogonal structures that were nearly identical to the American structure in both subject samples. The reliabilities of the five factors were quite high except for the 50-item measure of Agreeableness. The part-whole correlations between the 100-item and 50-item factors were high, as were the factor congruence coefficients between the heterosexual and the homosexual samples. Both versions of the IPIP Big-Five factor markers were strongly correlated with the scales from the Big-Five Inventory (BFI: John, Donahue, & Kentle, 1991), thus providing some concurrent validation in a Chinese context.     

医学伦理的多元、通约及其他--《医学伦理学》序

要重视医学伦理学的理论研究,案例分析不能完全取代理论讲授。医学伦理学是多元的,许多伦理问题的答案可有多种选择。许多不同伦理思想之间不仅有其差异,同时又是相容和可通约的。我们在尊重伦理多元化的同时,还应致力于寻求人类共同的道德准则和全球伦理的建设。     

College women’s value orientations toward family, career, and graduate school

This study was designed to examine how college women’s valuing of graduate education predicted their intentions to attend graduate school, using a new measure of the valuing of graduate school. A second purpose was to assess relations of college women’s perceptions of the relative importance of family and career to their valuing of graduate education. Two hundred and sixteen college women completed a newly developed survey that assessed these constructs. The items assessing task values were designed to assess components of task value defined by Eccles et al. (1983). Reliability and factor analyses demonstrated that the instrument adequately measured different components of task value. Multiple regression analyses demonstrated that components of task value predicted intentions to attend graduate school. The women were strongly career-oriented, and their orientations to career related positively to their valuing of graduate education.     

Effects of status and outcome on attributions and just-world beliefs: How the social distribution of success and failure may be rationalized

The distribution of success and failure to social groups is supported by lay theories about the characteristics of social groups and the causes of their outcomes, as well as by beliefs about entitlement of groups to succeed or fail. This paper presents a study where a target individual’s socio-economic status (high vs. low) and outcome in a major academic achievement task (success vs. failure) were manipulated in a 2 × 2 experimental design. It was found that high-status success and low-status failure, i.e. the system-consistent outcomes, were attributed relatively more to stable internal causes (ability), whereas high-status failure and low-status success, i.e. the system-inconsistent outcomes, were attributed relatively more to unstable causes (effort). Second, participants’ belief in a just world was higher in high-status success and low-status failure than in high-status failure and low-status success.     

Sexually dimorphic effect of an acute smoking manipulation on skin resistance but not on heart-rate during a cognitive verbal task

In a two-day, two-session experiment where smokers male and female college-student subjects worked on a cognitive verbal task during either the first or second day, and on a cognitive spatial task on the second or first day, smoking was manipulated as an acute independent variable by requiring 10+ hours of pre-experimental abstention, and providing a cigarette during the 15-minute rest period between the two sessions. Non-smoker female and male subjects underwent the same experiment, and hence served as controls for the effects of this acute-smoking manipulation. Overall adaptation (decreased arousal) to the experiment was manifested in a significant increase in skin resistance level (SRL) in all subjects, but when this adaptation effect was statistically controlled, there was a significant smokers by sex interaction during the verbal task only, such that SRL was increased by the cigarette in males, but decreased in females. In contrast, the same analysis indicated only a marked increase in heart-rate (HR) due to smoking, which was unaffected either by sex or by whether the task was the verbal or the (easier) spatial one. We interpret the SRL results as reflecting a sex difference in the direction of transient psychological arousal, and discuss it in relation to evidence in the literature based on self reports, and to evidence (based on HR in this study and on blood pressure in other studies) on physiological (cardiovascular) arousal.     

On Keats' generalization of the rasch model

Parameter estimation for Keats generalization of the Rasch model that takes account of guessing behavior is investigated. It is shown that no minimal sufficient statistics for the ability parameters independent of the difficulty parameters exist. Thus Andersen's conditional inference technique for consistent estimation is not applicable to Keats' model. The notion of separability of the parameters is generalized.     

Eta,disco, odisco,andF

Two coefficients are proposed for measuring the extent of overlap in distributions as a direct function of the variance between the arithmetic means (“disco” and “odisco”). They are designed to answer such questions as: “Given the value of a numerical variablex, to which population should an individual be assigned so that minimum error would be incurred?” This is just the reverse of the question addressed by ANOVA. These coefficients are shown to be analytic inx and they are related to Pearson's eta and Fisher'sF. Extensions of these coefficients (designed for univariate, one-way discrimination) tok-way and multivariate discriminant analysis and measurement of “interaction” are suggested.     

Protection of animal research subjects

The use of experimental animals, mostly rodents, in biomedical research and especially in oncology and immunology should be acknowledged with respect, recognizing the contribution of animal experimentation in the fascinating scientific progress in these disciplines of research. It is an obligation of the investigator to justify the scientific and ethical aspects of each study requiring the use of animals. The international guiding principles for using animals in biomedical research are well defined and have been distributed worldwide by the International Council for Laboratory Animal Science (ICLAS) since 1956, when this Organization was founded. In Poland the ICLAS philosophy and principles are highly respected and were implemented firstly by the members of the Commission on Biology of Experimental Animals appointed in 1962 by the Department of Medical Science of the Polish Academy of Science in Warsaw. Animal Protection Acts, first proclaimed in 1928 were gradually modified and improved. Actual legislation (enacted in 1997, 2003 and 2005) is consistent with EU Directives (86/609/EEC) and follows the internationally recommended principles that include ICLAS guidelines concerning animal welfare and care condition in biomedical research. The problem of “alternative methods” is briefly discussed. Dr. Donald Boisvert, CCAC — Canadian Council on Animal Care A lecture on the subject of this paper was presented at the 6th International Bioethics Conference entitled ‘The Responsible Conduct of Basic and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005. The author is the National Representative of Polish Academy of Science to the International Council for Laboratory Animal Science (ICLAS) and a Member of the ICLAS Governing Board.     

Emergent, untrained stimulus relations in many-to-one matching-to-sample discriminations in rats

The present experiment investigated whether rats formed emergent, untrained stimulus relations in many-to-one matching-to-sample discriminations. In Phase 1, rats were trained to match two samples (triangle and horizontal stripes) to a common comparison (horizontal stripes) and two additional samples (circle or vertical stripes) to another comparison (vertical stripes). Then, in Phase 2, the rats were trained to match the one sample (triangle) to a new comparison (black) and the other sample (circle) to another comparison (white). In the Phase 3 test, half the rats (consistent group) were given two new tasks in which the sample-correct comparison relation was consistent with any emergent stimulus relations that previously may have been learned. The remaining 6 rats (inconsistent group) were given two new tasks in which the sample-correct comparison relation was not consistent with any previously learned emergent stimulus relations. Rats in the consistent group showed more accurate performance at the start of Phase 3, and faster learning to criterion in this phase, as compared with rats in the inconsistent group. This finding suggests that rats may form emergent, untrained stimulus relations between the discriminative stimuli in many-to-one matching-to-sample discriminations.     

Between morality and repentance: recapturing "sin" for bioethics.

Distinguishing within "sin" the dimensions of anomia, hamartia, and asthenia makes it possible to analyze in greater detail the contrary manners in which traditional and post-traditional Christianities in this issue of Christian Bioethics endeavor to recapture what was lost when secular bioethics reconstructed the specifically spiritual-context-oriented normative commitments of Christianity in one-dimensionally moral terms. Various post-traditional attempts at securing moral orientation and resources for forgiveness, both of which secular bioethics finds increasingly difficult to provide, are critically reviewed. Their engagement of secular moral concepts and concerns, and even their adoption of an academically philosophical posture and language, is presented as responsible for their failure to adequately preserve what in traditional Christianity would count as prohibited vs. permitted, and advisable vs. non-advisable, or what would allow to resolve "tragic conflicts." The deeper reason for this failure lies in post-traditional Christianity's restricting the Christian life (with its central tension between love and the law) to what can be captured by cognitive categories. As the survey of several traditionally Christian accounts of sin in bioethics makes clear, both moral orientation (along with the resolution of "tragic" conflicts) and the sources of forgiveness are available, once that Christian life is framed in terms of persons' spirit-supported practical involvement in ascesis and liturgy, and once bioethical reflections are situated in the experiential context of such involvement.
