Cognitive Ability and Career Attainment: The Moderating Effects of Early Career Success
Three explanations regarding the prediction that early career success will moderate the relationship between cognitive ability and career attainment are presented along with an empirical examination of this issue. Using longitudinal data provided for 156 managerial, professional, and technical employees, significant moderating effects for an age-graded index of early career success were observed. The relationships between two measures of cognitive ability and later career job level were stronger for individuals identified as below average with respect to early career success than for their above average counterparts. These results agree with the proposition that the acquisition of knowledge, skills, and information is particularly dependent upon cognitive ability for inhviduals competing without the advantages associated with early career signals of high potential
Reframing Turnover/Personality Research in the Context of the Attraction-Selection-Attrition Hypothesis
This paper re-examines data originally reported by Cowan & Dreher (1983) in their examination of personality correlates of turnover among managerial, professional, and technical employees. It is intended to reframe the relationship between personality and turnover in light of recent attention on the attraction-selection-attrition hypothesis and to make the results of the original study more accessable to those studying these issues. Results show no relationship between homogeneity based on personality dimensions measured by the Guilford-Zimmerman Temperament Survey (GZTS) and attrition from the organization. Therefore, no support can be offered for the homogeneity hypothesis. Based on these and other failures to find significant relationships between personality dimensions and homogeneity, we suggest that future research about the causes and effects of homogeneity should be based on research that delineates the domain of organizational fit
Do People Make the Place?: An Examination of the Attraction-Selection-Attrition Hypothesis
This study tests the hypotheses that (1) congruence between internal need states and external environments drives the organizational-choice process, and (2) those attracted to particular organizations are more homogeneous than the applicant pool in general. Subjects were evaluated on fourteen needs using the Jackson Personality Research Form. They then viewed two video-taped segments of simulated campus interviews to gain information about two distinct organizational types. The interview segments entered the discussion in-progress to avoid any reference to a particular job which might introduce an occupational confound. Subjects received job offers from both organizations and were asked to indicate which of the two organizations they found more attractive by accepting one of the offers. Analysis of variance results indicated only weak support for the congruency hypothesis. Differences were observed in n Ach between the groups of subjects attracted to each organization. No differences were found for any of the other need strength measures. This suggests that the subjects attracted to the ifferent organizations are substantially similar. Implications for the homogeneity hypothesis are discussed and suggestions for further study of this concept are offered
Measurement and Dimensionality of Compensation Satisfaction in Law Enforcement
This research examined the dimensionality of carpensation satisfaction for the occupational area of law enforcanent by analyzing the factor structure of Henanan and SChwab\u27s (1985) Pay Satisfaction Questionnaire (PSQ) . The PSQ is intended to measure four facets of compensation satisfaction: 1) pay level, 2) benefits, 3) pay raises, and 4) pay structure-administration. Previous research showed support for the PSQ level and benefits scales, but yielded equivocal results for the raises and structure-administration scales. Previous research also showed that the factor structure of the PSQ varied by job classification group. The present study, using data fran 1189 unifomed law enforcanent officers anployed by eight different state police or highway patrol organizations, found that a three-factor solution (level, benefits, and structure-administration) represents the appropriate dimensional structure for compensation satisfaction in the occupational area of law enforcanent, at least within the danain of the 18 itans of the PSQ. These findings are integrated with those of previous research, and implications for research and practice are discussed
Computational structure‐based drug design: Predicting target flexibility
The role of molecular modeling in drug design has experienced a significant revamp in the last decade. The increase in computational resources and molecular models, along with software developments, is finally introducing a competitive advantage in early phases of drug discovery. Medium and small companies with strong focus on computational chemistry are being created, some of them having introduced important leads in drug design pipelines. An important source for this success is the extraordinary development of faster and more efficient techniques for describing flexibility in three‐dimensional structural molecular modeling. At different levels, from docking techniques to atomistic molecular dynamics, conformational sampling between receptor and drug results in improved predictions, such as screening enrichment, discovery of transient cavities, etc. In this review article we perform an extensive analysis of these modeling techniques, dividing them into high and low throughput, and emphasizing in their application to drug design studies. We finalize the review with a section describing our Monte Carlo method, PELE, recently highlighted as an outstanding advance in an international blind competition and industrial benchmarks.We acknowledge the BSC-CRG-IRB Joint Research Program in Computational Biology.

In Search for a Long-run Relationship between Aid and Growth: Pitfalls and Findings
In this paper we investigate the relationship between per capita income and foreign aid for a panel of 131 (alternatively 52) recipient countries over the period 1960 to 2006 by employing annual data and 5-year averages. Reliance on standard panel estimation techniques, such as 2-ways FE estimation, panel GMM and SUR estimation, points to some pitfalls (impossibility of possible cointegration between aid and growth, autocorrelation of the error terms, endogeneity of the variables) that must be dealt with panel time series techniques (such as panel unit root test, panel cointegration tests and panel dynamic feasible generalized least squares estimation (DFGLS)). Estimations with DFGLS show that aid has an insignificant or a minute negative significant impact on per capita income. This result holds for countries with above- and below-average aid-to-GDP ratios, for countries with different levels of human development, with different income levels and from different regions of the world. It can be shown that by not controlling for autocorrelation, one erroneously attributes to aid a larger, significant negative impact on per capita income. We also find that aid has a significant positive (even though) small impact on investment, but a negative and significant impact on domestic savings (crowding out) and the real exchange rate (appreciation).Foreign aid; real per capita income; panel time series techniques; dynamic feasible generalized linear least squares (DFGLS)
Physicochemical analysis of rotavirus segment 11 supports a 'modified panhandle' structure and not the predicted alternative tRNA-like structure (TRLS)
.Rotaviruses are a major cause of acute gastroenteritis, which is often fatal in infants. The viral genome consists of 11 double-stranded RNA segments, but little is known about their cis-acting sequences and structural elements. Covariation studies and phylogenetic analysis exploring the potential structure of RNA11 of rotaviruses suggested that, besides the previously predicted "modified panhandle" structure, the 5' and 3' termini of one of the isoforms of the bovine rotavirus UKtc strain may interact to form a tRNA-like structure (TRLS). Such TRLSs have been identified in RNAs of plant viruses, where they are important for enhancing replication and packaging. However, using tRNA mimicry assays (in vitro aminoacylation and 3'- adenylation), we found no biochemical evidence for tRNA-like functions of RNA11. Capping, synthetic 3' adenylation and manipulation of divalent cation concentrations did not change this finding. NMR studies on a 5'- and 3'-deletion construct of RNA11 containing the putative intra-strand complementary sequences supported a predominant panhandle structure and did not conform to a cloverleaf fold despite the strong evidence for a predicted structure in this conserved region of the viral RNA. Additional viral or cellular factors may be needed to stabilise it into a form with tRNA-like properties
Organizational Search and Choice Revisited: The Role of Human Resource Systems in the Applicant\u27s Decision Making Process
Over the past decade we have learned a lot about how individuals choose organizations in which to work. However, this literature has generally failed to consider the role of an important class of attributes; the human resource systems that operate within organizations. Reward systems and mobility systems have unique motivating characteristics, are relatively visible, and vary widely between organizations. This paper attempts to make explicit when and how these variables might influence organizational attractiveness and applicants\u27 decision making processes
