Structure versus process: Mach, Hertz, and the Normative Aspect of Science

In the end of the nineteenth century, there was a remarkable ‘empiricist attitude’ found among certain philosopher-scientists, an attitude which arguably emerged in the main as a reaction to the anti-scientific mood prevalent in the culture that time. Those philosopher-scientists, such as Mach and Hertz, were particularly anxious to emphasize and laud the privileged status of the empirical dimension ofour scientific knowledge, distinguishing it carefully from the theoretical constructions and hypothetical entities that are ordinarily posited by scientists. Yet, as I exhibit in this article, there were certain crucial philosophical differences between these two thinkers with respect to their general conception of scientific theories and scientific norms guiding the activity. I suggest further that the most central difference in this context between Mach and Hertz can justifiably (and, perhaps, more fruitfully) be articulated and reckoned in traditional andcontemporary epistemological terms.

Personal Values and Intended Self‐Presentation during Job Interviews: A Cross‐Cultural Comparison

This study examined the impact of personal values on intended self‐presentation during job interviews among German, Ghanaian, Norwegian, and Turkish students (total N= 1,474). We also sought to explain cultural differences in self‐presentation among these groups. The Cultural Impression Management Scale for applicants (CIM‐A) and the Portrait Values Questionnaire were administered. A multigroup MIMIC model with invariant measurement and structural weights was supported, in which achievement, security, and benevolence values predicted a latent impression management factor. Intended impression management scores were significantly higher in the Ghanaian and Turkish samples than in the Norwegian and German samples. Values (achievement and security) accounted for 19.6 per cent of the cross‐cultural differences in self‐presentation. Adding acquiescence as an additional predictor (interpreted here as a measure of communication style) decreased the cross‐cultural differences by 52.8 per cent. It is concluded that values are similarly related to intended self‐presentation across these four groups, even though the cross‐cultural differences in mean scores in both sets of variables were considerable.     

Are your cross‐ethnic friends ethnic and/or national group identifiers? The role of own and perceived cross‐ethnic friend's identities on outgroup attitudes and multiculturalism

We investigated how own ethnic and national identities and perceived ethnic and national identities of close cross‐ethnic friends may predict outgroup attitudes and multiculturalism among Turkish (majority status, N = 197) and Kurdish (minority status, N = 80) ethnic group members in Turkey (M_age = 21.12, SD = 2.59, 69.7% females, 30.3% males). Compared with Turkish participants, Kurdish participants were more asymmetrical in rating their cross‐ethnic friend's identities relative to their own, reporting higher ethnic identity, but lower national identity for themselves. Own ethnic identity was negatively associated with attitudes and multiculturalism, whereas own national identity was positively associated with only attitudes. Perceived cross‐ethnic friend's national identity was positively related to both outgroup attitudes and multiculturalism. Shared national identification (high levels of own and friend's national identity) led to most positive outgroup attitudes and highest support for multiculturalism. Findings were discussed in the light of social identity and common ingroup identity models.     

Which One Triggers the Other? Technological or Social Innovation

The term innovation has sometimes been used as a synonym for technological innovation until the concept of social innovation attracted academic attention. Since then, these two types of innovation have been investigated individually. It can be claimed that, despite the great importance of social innovation studies, technological innovation studies received more attention. In addition, there are limited studies that have examined technological and social innovation together. The aim of this study was to examine the causal relationship between technological and social innovations. The impact of entrepreneurial characteristics on social innovation was also analyzed. This study was based on a comprehensive field study including 767 university students from 10 universities from different regions of Turkey. Regression analyses and structural equation modeling confirmed that social and technological innovation were related to one another, and both were correlated with a particular constellation of personal characteristics.     

Effects of Daylight Saving Time changes on stock market volatility: a reply

There is a rich array of evidence that suggests that changes in sleeping patterns affect an individual's decision-making processes. A nationwide sleeping-pattern change happens twice a year when the Daylight Saving Time (DST) change occurs. Kamstra, Kramer, and Levi argued in 2000 that a DST change lowers stock market returns. This study presents evidence that DST changes affect the relationship between stock market return and volatility. Empirical evidence suggests that the positive relationship between return and volatility becomes negative on the Mondays following DST changes.     

Creativity and Tolerance of Ambiguity: An Empirical Study

This study examines the relationship between creativity and tolerance of ambiguity. Participants were parents and their adolescent children. Three measures of creativity were used: a divergent thinking task, a story‐writing task and self‐evaluation of creative attitudes and behavior. Participants completed two self‐report measures of tolerance of ambiguity: the short version of the “Measurement of Ambiguity Tolerance” (Norton, 1975; Zenasni & Lubart, 2001) and the “Behaviour Scale of Tolerance/Intolerance for Ambiguity” (Stoycheva, 1998, 2003). Tolerance of ambiguity was significantly and positively related to creativity. Creativity of parents was related to their adolescents' creativity. However, parents' tolerance of ambiguity was not related to adolescents' tolerance of ambiguity or creativity.     

Typing Speed as a Confounding Variable and the Measurement of Quality in Divergent Thinking

The need to control for writing or typing speed when assessing divergent-thinking performance has been recognized since the early ‘90s. An even longer tradition in divergent-thinking research has the issue of scoring the responses for quality. This research addressed both issues within structural equation modeling. Three dimensions of originality—uncommonness, remoteness, and cleverness—were used to derive an overall quality score. Mixed evidence was found in Study 1 for the direct effect of typing speed on fluency. In addition, indirect effects of typing speed via cognitive complexity on overall quality of ideas were uncovered but marginal in both Study 1 and Study 2. This indirect effect was also found for cleverness in Study 2. Another indirect effects of typing speed via fluency was found for cleverness and uncommonness. These findings indicate that controlling for typing speed is important in online divergent-thinking assessment. The inter-relations of various quality scores pertaining to the dimensions of uncommonness, remoteness, and cleverness were promising in terms of convergent validity. Important problems with respect to these scores were identified and discussed to guide future attempts to measure quality in DT.
