Age identity: A cross-cultural global approach:

Abstract: A combination of recent international surveys establishes surprising universality of the subjective and ideal age self-construal constructs appraised in years. Results showed that in 18 culturally disparate countries, age-of-birth was older than subjective/cognitive age self-construal; in 15 nations ideal/ desired ages were measured as well, and those were even younger. Implications of the construct's universality , as well as the reliability, validity, and equivalence of the different measurements of age identity in a cross-cultural research context, are discussed from a global perspective.

GWAS meta-analysis reveals novel loci and genetic correlates for general cognitive function: a report from the COGENT consortium

Abstract: The complex nature of human cognition has resulted in cognitive genomics lagging behind many other fields in terms of gene discovery using genome-wide association study (GWAS) methods. In an attempt to overcome these barriers, the current study utilized GWAS meta-analysis to examine the association of common genetic variation (~8M single-nucleotide polymorphisms (SNP) with minor allele frequency ⩾1%) to general cognitive function in a sample of 35 298 healthy individuals of European ancestry across 24 cohorts in the Cognitive Genomics Consortium (COGENT). In addition, we utilized individual SNP lookups and polygenic score analyses to identify genetic overlap with other relevant neurobehavioral phenotypes. Our primary GWAS meta-analysis identified two novel SNP loci (top SNPs: rs76114856 in the CENPO gene on chromosome 2 and rs6669072 near LOC105378853 on chromosome 1) associated with cognitive performance at the genome-wide significance level (P<5 × 10-8). Gene-based analysis identified an additional three Bonferroni-corrected significant loci at chromosomes 17q21.31, 17p13.1 and 1p13.3. Altogether, common variation across the genome resulted in a conservatively estimated SNP heritability of 21.5% (s.e.=0.01%) for general cognitive function. Integration with prior GWAS of cognitive performance and educational attainment yielded several additional significant loci. Finally, we found robust polygenic correlations between cognitive performance and educational attainment, several psychiatric disorders, birth length/weight and smoking behavior, as well as a novel genetic association to the personality trait of openness. These data provide new insight into the genetics of neurocognitive function with relevance to understanding the pathophysiology of neuropsychiatric illness.

Excess Market Value, the Multinational Corporation, and Tobin's q-Ratio

Abstract: The results of this study show that there is a positive and significant relationship between excess market value of multinational corporations and the degree of international involvement as measured by foreign sales percentage. However, the excess market value is not determined by the number of foreign subsidiaries, nor the interaction between foreign sales and the number of foreign subsidiaries. The relationship between excess market value and the two frequently used measures of monopoly power–concentration ratio and the Lerner Index–was also examined. This study found that the Lerner Index contributes significantly in explaining excess market value but concentration ratio does not. Furthermore, the positive and significant coefficients of advertising and R & D intensity serve as evidence that product market imperfections appear to play a bigger role in explaining the excess market value experienced by MNCs during our sample period.

LinkedIn and recruitment: how profiles differ across occupations

Abstract: Purpose – The purpose of this paper is to identify the elements of a LinkedIn profile that hiring professionals focus on most, and then examine LinkedIn profiles in terms of these identified elements across different industries. Design/methodology/approach – The methodology was comprised of two phases. In the first phase, researchers interviewed hiring professionals to determine their usage of LinkedIn. In the second phase, LinkedIn group member profiles from three industries – HR, sales/marketing and industrial/organizational (I/O) psychology – were compared on the 21 variables identified in Phase 1 (n=288). Findings – χ2 and ANOVA tests showed significant differences with respect to ten of the LinkedIn variables in how people presented themselves across the three groups. There were also several gender differences found. Research limitations/implications – A general limitation was the use of a qualitative research approach. A limitation of Phase 1 was that only a small sample of New York City-based hirin...
