Structure of organizational trust in military-type and civilian organizations: Validation of the Organizational Trust Questionnaire

Contemporary research on organizational trust views it as either rational or relational phenomenon that is a result of interpersonal bonds or cooperative relationships between the trusting parties. Resent studies agree that a certain degree of trust must be embedded in and enacted through organizational interactions and structures, taking trust from a purely interpersonal phenomenon to a more complex organizational phenomenon that has multiple antecedents;This study hypothesizes that that an organizational member\u27s intention to trust others in the organization is affected by six factors: (1) the individual\u27s propensity to trust, (2) co-workers\u27 character and behaviors, (3) bosses\u27 character and behavior, (4) organizational structures, (5) interactions outside of the organization, and (6) the individual\u27s propensity to distrust. The study also suggests that individual intention to trust others in organizations varies depending on the degree of organizational formalization and centralization;To confirm the existence of the proposed factors and explore the potential influence of structural dimensions on individual intention to trust, the Organizational Trust Questionnaire (the OTQ) was constructed and distributed to the employees of a law enforcement agency and a university. The data was analyzed using exploratory and confirmatory factor analyses and the Structural Equations Modeling technique;The findings validate the OTQ and establish its usability in both civilian and military-type organizations. The results demonstrate that faculty members and professional and scientific employees of the university have higher levels of intention to trust than sworn officers of a law enforcement agency and merit employees of the university. These differences are attributed to the differences in levels of centralization and formalization in the two organizations

Effects of parent-child affective quality during high school years on subsequent substance use

The literature indicates that the quality of affective relationships between youth and parents is associated with lower levels of a range of problem behaviors during childhood, early and late adolescence. While the protective effect of parental monitoring on substance use in the high school and post high school years has been demonstrated, there is a knowledge gap concerning effects of parent-child affective quality (PCAQ) during the same periods. We tested a conceptual theoretical model to examine the effects of PCAQ on substance use following high school. The sample was from a RCT that assessed adolescents in rural Iowa from the seventh grade through two years after high school (N=456). We specified direct effects of PCAQ in 12th grade on drunkenness, smoking and illicit drug use during the two years immediately following high school graduation. We also specified the effects of early substance use initiation (alcohol, tobacco and marijuana use reported at baseline) on later use. The direct effect of PCAQ in 12th grade on substance use was significant for all substances during at least one of the two years past graduation (ypg). Results were: drunkenness 1 ypg, β=-.126, p<.05; smoking 1 ypg, β=-.119, p<.05; 2 ypg, β=-.146, p<.05; illicit drug use 2 ypg, β=-.165, p<.05. Some significant indirect effects of PCAQ at baseline, via PCAQ at 12th grade, were found. Results also indicated significant direct effects of early initiation on two of the three substances, albeit with a different pattern of effects over time for each substance by years post high school. Importantly, while early initiation remains the strongest predictor of long-term tobacco and illicit drug use, results show how PCAQ might reduce its harmful effects.peer-reviewe

FGF4 Independent Derivation of Trophoblast Stem Cells from the Common Vole

The derivation of stable multipotent trophoblast stem (TS) cell lines from preimplantation, and early postimplantation mouse embryos has been reported previously. FGF4, and its receptor FGFR2, have been identified as embryonic signaling factors responsible for the maintenance of the undifferentiated state of multipotent TS cells. Here we report the derivation of stable TS-like cell lines from the vole M. rossiaemeridionalis, in the absence of FGF4 and heparin. Vole TS-like cells are similar to murine TS cells with respect to their morphology, transcription factor gene expression and differentiation in vitro into derivatives of the trophectoderm lineage, and with respect to their ability to invade and erode host tissues, forming haemorrhagic tumours after subcutaneous injection into nude mice. Moreover, vole TS-like cells carry an inactive paternal X chromosome, indicating that they have undergone imprinted X inactivation, which is characteristic of the trophoblast lineage. Our results indicate that an alternative signaling pathway may be responsible for the establishment and stable proliferation of vole TS-like cells

Azimuthal Correlations within Exclusive Dijets with Large Momentum Transfer in Photon-Lead Collisions

International audienceThe structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process that is considered to be sensitive to the underlying nuclear gluon polarization. This study uses a data sample of ultraperipheral lead-lead collisions at sNN=5.02  TeV, corresponding to an integrated luminosity of 0.38  nb-1, collected with the CMS experiment at the LHC. The measured second harmonic of the correlation between the sum and difference of the two jet transverse momentum vectors is found to be positive, and rising, as the dijet transverse momentum increases. A well-tuned model that has been successful at describing a wide range of proton scattering data from the HERA experiments fails to describe the observed correlations, suggesting the presence of gluon polarization effects
