A New Database on the Structure and Development of the Financial Sector

Abstract: This article introduces a new database of indicators of financial structure and financial development across countries and over time. The database is unique in that it combines a wide variety of indicators that measure the size, activity, and efficiency of financial intermediaries and markets. It improves on previous efforts by presenting data on the public share of commercial banks, introducing indicators of the size and activity of nonbank financial institutions, and constructing measures of the size of bond and primary equity markets. This article introduces a new database, the first to provide comprehensive measures of the development, structure, and performance of the financial sector. This database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries, such as insurance companies, pension funds, and non-deposit money banks. It is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets. In constructing the database, authors carefully deflate measures and match stock and flow variables.

The core self‐evaluations scale: development of a measure

Abstract: Despite an emerging body of research on a personality trait termed core self-evaluations, the trait continues to be measured indirectly. The present study reported the results of a series of studies that developed and tested the validity of the Core Self-Evaluations Scale (CSES), a direct and relatively brief measure of the trait. Results indicated that the 12-item CSES was reliable, displayed a unitary factor structure, correlated significantly with job satisfaction, job performance, and life satisfaction, and had validity equal to that of an optimal weighting of the 4 specific core traits (self-esteem, generalized self-efficacy, neuroti-cism, and locus of control), and incremental validity over the 5-factor model. Overall, results suggest that the CSES is a valid measure that should prove useful in applied psychology research.

New directions in equity research.

Abstract: This article consists of four sections: The first section elucidates a general theory of social behavior—equity theory. Equity theory consists of four propositions designed to predict when individuals will perceive that they are justly treated and how they will react when they find themselves enmeshed in unjust relationships. The second section summarizes the extensive research that has been conducted to lest equity theory. The third section points out the ways in which equity theory interlocks with other major social psychological theories. The final section hints at some ways in which equity theory can be applied to understanding social problems. THE THEORETICAL FORMULATION The proposition that individuals seek for themselves maximum reward at minimum cost is hardly startling. Theories in a wide variety of disciplines rest on the assumption that "Man is selfish." Psychologists believe that behavior can be shaped by the careful application of reinforcement s. Economists assume that individuals will purchase desired products at the lowest available price. Moral philosophers conclude that the ideal society can only be one which insures the "greatest good for the greatest number." Politicians contend that "Every man has his price." Equity theory, too, rests on the assumption that man is selfish. Thus, our first proposition states: Proposition I: Individuals will try to maximize their outcomes (where outcomes equal rewards minus costs). If everyone were unrestrained in his attempts to get what he wanted, everyone would suffer. Every man would attempt to monopolize community resources; every man would be continually confronted by rivals bent on reclaiming these resources. Only by working out a compromise can the group avoid continual warfare and maximize collective reward. This fact is acknowledged in Proposition II A:

Large-scale meta-analysis of genome-wide association data identifies six new risk loci for Parkinson's disease

Abstract: We conducted a meta-analysis of Parkinson's disease genome-wide association studies using a common set of 7,893,274 variants across 13,708 cases and 95,282 controls. Twenty-six loci were identified as having genome-wide significant association; these and 6 additional previously reported loci were then tested in an independent set of 5,353 cases and 5,551 controls. Of the 32 tested SNPs, 24 replicated, including 6 newly identified loci. Conditional analyses within loci showed that four loci, including GBA, GAK-DGKQ, SNCA and the HLA region, contain a secondary independent risk variant. In total, we identified and replicated 28 independent risk variants for Parkinson's disease across 24 loci. Although the effect of each individual locus was small, risk profile analysis showed substantial cumulative risk in a comparison of the highest and lowest quintiles of genetic risk (odds ratio (OR) = 3.31, 95% confidence interval (CI) = 2.55–4.30; P = 2 × 10−16). We also show six risk loci associated with proximal gene expression or DNA methylation.

The Hierarchical Taxonomy of Psychopathology (HiTOP): A Dimensional Alternative to Traditional Nosologies

Abstract: The reliability and validity of traditional taxonomies are limited by arbitrary boundaries between psychopathology and normality, often unclear boundaries between disorders, frequent disorder co-occurrence, heterogeneity within disorders, and diagnostic instability. These taxonomies went beyond evidence available on the structure of psychopathology and were shaped by a variety of other considerations, which may explain the aforementioned shortcomings. The Hierarchical Taxonomy Of Psychopathology (HiTOP) model has emerged as a research effort to address these problems. It constructs psychopathological syndromes and their components/subtypes based on the observed covariation of symptoms, grouping related symptoms together and thus reducing heterogeneity. It also combines co-occurring syndromes into spectra, thereby mapping out comorbidity. Moreover, it characterizes these phenomena dimensionally, which addresses boundary problems and diagnostic instability. Here, we review the development of the HiTOP and the relevant evidence. The new classification already covers most forms of psychopathology. Dimensional measures have been developed to assess many of the identified components, syndromes, and spectra. Several domains of this model are ready for clinical and research applications. The HiTOP promises to improve research and clinical practice by addressing the aforementioned shortcomings of traditional nosologies. It also provides an effective way to summarize and convey information on risk factors, etiology, pathophysiology, phenomenology, illness course, and treatment response. This can greatly improve the utility of the diagnosis of mental disorders. The new classification remains a work in progress. However, it is developing rapidly and is poised to advance mental health research and care significantly as the relevant science matures. (PsycINFO Database Record
