The odds of resilience

This article presents sample research designs for the investigation of questions concerning resilience. Sample hypothesis from specific research designs are described in the form of odds ratios.     

Cognitive styles,abilities, and aptitudes: Are they dependent or independent?

An important question that must be answered is whether cognitive styles, abilities, and aptitudes provide complementary or redundant information regarding students' characteristics. Measures of 6 styles, 6 abilities, and 12 aptitudes were administered to 201 Navy recruits. Relationships among all cognitive attributes and between sets of styles and abilities as well as styles and aptitudes were examined by computing product-moment correlations and two canonical analyses. A principal-factor analysis and varimax rotation were also computed for all 24 characteristics. The results indicated that many styles are significantly related to abilities and aptitudes. However, the amount of shared variance between styles and abilities or aptitudes is small. Three significant factors were extracted (i.e., technical aptitude, verbal ability, and general problem solving) which underlie much of the variability of these cognitive characteristics. The data demonstrated (1) the relative dependence of most cognitive styles with abilities and aptitudes inherent to general problem solving, and (2) the relative independence of some cognitive styles from technical aptitude and verbal ability dimensions.     

Gender,Science, and Scientific Organizations in Germany

This article considers the situation of women in science in Germany. We argue that scientific organizations play a crucial role in shaping science careers, often with different consequences for men and women. To sustain the argument, we offer a study of the careers of male and female scientists in the Max Planck Society. Our findings show that external support increases career options and opportunities for men, but not for women scientists.     

Optimizing knowledge transfer by new employees in companies

Companies realize innovations by creating and implementing new knowledge. One possible source of innovative ideas are new employees. Based on an existing game-theoretic model the conditions of efficient knowledge transfer in a team are analyzed. Offering knowledge to a colleague cannot be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives, which motivate the employees to act in favor of the company. The aim of this paper is to show what influences the propensity of the employees to engage in knowledge transfer and how the management can design the incentive structure for optimal transfer. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is at least partly generalized on more players. The relevance of the adequate team size is shown: too few or too many developers decrease the remaining company profit. A further result is that depending on the cost structure, perfect knowledge transfer is not always best for the profit of the company.     

Preschool Verbal and Nonverbal Ability Mediate the Association Between Socioeconomic Status and School Performance

We compared the extent to which the long-term influence of family socioeconomic status (SES) on children's school performance from age 7 through 16 years was mediated by their preschool verbal and nonverbal ability. In 661 British children, who completed 17 researcher-administered ability tests at age 4.5 years, SES correlated more strongly with verbal than nonverbal ability (.39 vs. .26). Verbal ability mediated about half of the association between SES and school performance at age 7, while nonverbal ability accounted for a third of the link. Only SES, but not verbal or nonverbal ability, was associated with changes in school performance from age 7 to 16. We found that SES-related differences in school performance are only partly transmitted through children's preschool verbal abilities.     

Concept maps for assessing change in learning: a study of undergraduate business students in first-year marketing in China

This paper explains the application of concept mapping to help foster a learning-centred approach. It investigates how concept maps are used to measure the change in learning following a two-week intensive undergraduate Marketing Principles course delivered to 162 Chinese students undertaking a Bachelor of Business Administration programme in China. Using four scoring procedures (breadth of knowledge, relational quality, structural quality and holistic quality), student learning is assessed in terms of prior and new knowledge, as well as improvement in knowledge structure. Concept map scores are correlated with conventional measures of overall student performance. The results provide strong evidence for improvement in students’ ability to externalise new learned concepts resulting from intensive instruction. Incorporating concept maps as a contemporary method of learning in the curriculum potentially enriches student learning, provides a measure of the impact of teaching on students’ learning and adds value to students’ higher education experience.
