Testing the relationship between personality characteristics,contextual factors and entrepreneurial intentions in a developing country

Drawing upon the theory of planned behaviour (TPB ), we developed and tested a conceptual model which integrates both internal personality factors and external contextual factors to determine their associations with motivational factors and entrepreneurial intentions (EIs ). We then investigated if the model of EI applies in a developing country, namely Iran. We also set out to identify the most relevant factors for EI within this developing country context. Do distal predictors of EI including personality factors (i.e. need for achievement, risk taking and locus of control) and contextual factors (i.e. perceived barriers and support) significantly relate to EI via proximal predictors including motivational factors (i.e. attitudes towards entrepreneurship and perceived behavioural control [PBC])? Data were collected on 331 students from 7 public universities. The findings support the TPB for EI in Iran. All three motivational factors related to EI , but PBC showed the strongest association, which is different than in developed country contexts. Possible explanations for these differences are discussed. All three personality characteristics indirectly related to EI via the proximal attitudes towards entrepreneurship and PBC . Perceived contextual support and barriers indirectly related to EI via proximal PBC while perceived barriers also directly related to EI .     

Rehearsal strategies during motor-sequence learning in old age: execution vs motor imagery

Motor imagery and action-based rehearsal were compared during motor sequence-learning by young adults (M = 25 yr., SD = 3) and aged adults (M = 63 yr., SD = 7). General accuracy of aged adults was lower than that of young adults (F(1,28) = 7.37, p =.01) even though working-memory capacity was equivalent in the two groups. Motor imagery and rehearsal by action increased accuracy in both age groups, compared with minimization of opportunity for rehearsal (F(1,28) = 30.95, p < .001), but no interaction was found with age group, which suggests that young and aged adults were equally capable of motor imagery and action-based rehearsal. It was assumed that differences in performance between young and aged participants related to the formation of mental representations of sequences and integration of new elements into these representations rather than the capacity for motor imagery or rehearsal by action per se. The current study was exploratory and involved a relatively small sample of 15 participants per age group. Caution must be taken when considering the results.     

Reading the tea leaves in an intelligent Coffee Corner: Challenges for understanding behavior

This article discusses the challenges for methodological innovation on the basis of experiences in an experimental Living Lab setting: a context-aware Coffee Corner in a research institute. A context-aware infrastructure collects sensory information on users while they move and interact. People getting coffee can use a variety of services offered in the intelligent environment at the Coffee Corner’s site; for example, a colleague-radar application allows users to see the current positions of their colleagues in the building. At the same time, it identifies and authenticates users using proximity-aware and context-aware security features. Apart from proximity and context awareness, the analysis of contextual data allows the construction of a behavioral model of users that can be used to customize the services offered at the Coffee Corner. We explain how the Living Lab allows us to measure behavior in context in an unobtrusive and trustworthy way (e.g., by respecting a user’s right to privacy).     

Sanctions and moral judgments: The moderating effect of sanction severity and trust in authorities

In order to induce people to follow rules, sanctions are often introduced. In this paper we argue for the importance of studying the positive influence of sanctioning systems on people's moral convictions regarding the rule advocated by the sanction and of studying factors that moderate this influence. In three experiments we tested the influence of sanction severity and showed that severe sanctions evoke stronger moral judgments with regard to rule‐breaking behavior and stronger social disapproval towards rule‐breakers than mild sanctions. This was particularly the case when trust in authorities is high rather than low. Implications of these findings are discussed. Also, a framework is proposed to understand the possible circumstances that determine whether sanctions either increase or decrease moral norms. Copyright © 2008 John Wiley & Sons, Ltd.     

Multidimensional Adaptive Testing with Optimal Design Criteria for Item Selection

Several criteria from the optimal design literature are examined for use with item selection in multidimensional adaptive testing. In particular, it is examined what criteria are appropriate for adaptive testing in which all abilities are intentional, some should be considered as a nuisance, or the interest is in the testing of a composite of the abilities. Both the theoretical analyses and the studies of simulated data in this paper suggest that the criteria of A-optimality and D-optimality lead to the most accurate estimates when all abilities are intentional, with the former slightly outperforming the latter. The criterion of E-optimality showed occasional erratic behavior for this case of adaptive testing, and its use is not recommended. If some of the abilities are nuisances, application of the criterion of A _s -optimality (or D _s -optimality), which focuses on the subset of intentional abilities is recommended. For the measurement of a linear combination of abilities, the criterion of c-optimality yielded the best results. The preferences of each of these criteria for items with specific patterns of parameter values was also assessed. It was found that the criteria differed mainly in their preferences of items with different patterns of values for their discrimination parameters.

Neural coding of reward magnitude in the orbitofrontal cortex of the rat during a five-odor olfactory discrimination task

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory discrimination “go”/“no-go” task in which five different odor stimuli were predictive for various amounts of reward or an aversive reinforcer. Neural correlates related to both actual and expected reward magnitude were observed. Responses related to reward expectation occurred during the execution of the behavioral response toward the reward site and within a waiting period prior to reinforcement delivery. About one-half of these neurons demonstrated differential firing toward the different reward sizes. These data provide new and strong evidence that reward expectancy, regardless of reward magnitude, is coded by neurons of the rat OBFc, and are indicative for representation of quantitative information concerning expected reward. Moreover, neural correlates of reward expectancy appear to be distributed across both motor and nonmotor phases of the task.     

The Dutch curve: The introduction and reception of intelligence testing in the Netherlands, 1908–1940

In the Netherlands, intelligence testing has been pragmatic and has not generated the heated controversies found in other cultures. Four historical reasons are presented for this paradoxical development. First, the Binet test was used mainly as a diagnostic instrument for professional judgments about admission to special education. Second, the eugenic use of IQ tests was moderated by the marginal position of eugenics in Dutch society. Third, the process of “pillarization” gave considerable power to denominational groups in Dutch society, and they strongly criticized deterministic ideas about the heredity of intelligence. Fourth, the educational scientist, cognitive psychologist, philosopher, and government adviser, Philip Kohnstamm, was very influential in Dutch science and politics. He rejected intelligence testing and its deterministic connotations in favor of the idea of the educability of cognitive capacities. © 1998 John Wiley & Sons, Inc.     

Educated and underemployed: Refugee integration into the Canadian labour market

This study explores issues of access to high-status occupations in the Canadian labour market, with particular emphasis on refugees who were in professional or managerial positions prior to their arrival in Canada. The study is based on interviews with a sample of 525 adult refugees who were initially resettled in the province of Alberta between 1992 and 1997. About two thirds of the respondents came from former Yugoslavia, the remainder from countries in the Middle East, Central America, Africa, and Southeast Asia. Despite the generally high educational attainment of these refugees, the results show that they experience, much higher rates of unemployment, part-time employment, and temporary employment than do Canadian-born individuals. A variety of structural factors operating in a segmented Canadian labour market help to explain the downward mobility of these highly qualified refugees. The policy implications of these results are examined in detail.     

Personality traits and cognitive styles as risk factors for serious suicide attempts among young people.

The contribution of a series of measures of personality and/or cognitive style to serious suicide attempt risk in young people was examined in a case-control study. Individuals making suicide attempts had elevated odds of hopelessness, neuroticism, introversion, low self-esteem, impulsiveness, and external locus of control. When allowance was made for intercorrelations between these measures, hopelessness, neuroticism, and external locus of control remained significant risk factors for serious suicide attempt; self-esteem, extraversion, and impulsiveness were not significantly associated with suicide attempt risk. Nonsignificant findings were explained by the presence of substantial correlations between these measures and measures of hopelessness, neuroticism, and external locus of control.
