Growth Conditions for Zinc Crystals

Previous work by Schilling1 showed that additions of Cadmium were necessary to produce conditions favorable to growth of single crystals. The present work has to do with the effect of other impurities on growth conditions. At present it has been found, by using zinc with somewhat less iron impurity than Schilling\u27s zinc but with the same addition of Cadmium, that the region favorable to growth is more like the original one of Hoyem and Tyndall and considerably different from Schilling\u27s region

Pay-for-Performance Systems in State Government: Perceptions of State Agency Personnel Managers*

Pay for performance has been a widely used method of compensation in the public sector since the early 1980s, but a growing body of research has indicated that numerous problems can be associated with the application of performance-based compensation systems In late 1993, the federal government, after years of difficulty experienced with its merit pay program, took a significant step back from pay for performance through passage of the Performance Management and Recognition System Termination Act This research seeks to determine whether state governments are becoming similarly disenchanted with pay for performance To gain insight into this question, a survey was administered to a nationwide random sample of state agency personnel management executives Results indicate that pay for performance remains as popular as ever in state government, and that nearly all of the systems in the states utilize merit pay despite difficulties often associated with that approach to pay for performance.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Development and Simulation Testing of a Computerized Adaptive Measure of Communicative Functioning in Aphasia

Computerized adaptive testing (CAT), based on the mathematical framework of item response theory (IRT), has increasingly been implemented in patient reported outcome measures over the past decade (Fries, Bruce, & Cella, 2005). Given a calibrated item pool fit by an appropriate IRT measurement model, a CAT can produce reliable ability estimates more efficiently than traditional paper-and-pencil tests by administering items that are most informative given the examinee’s estimated ability level (Wainer, 2000). As conventional measures employed in the measurement of aphasia were developed under traditional measurement theory, many of these measures are long and inefficient, and are consequently unsuitable for regular clinical care. In addition, these conventional measures often fail to meet the needs of many community-dwelling stroke survivors whose impairments falls outside the range reliably measured by these tests (Doyle et al. 2012). IRT-based and in particular CAT patient reported outcome measures offer the possibility of substantial improvements in measurement technology for persons with aphasia

Thinking about a limited future enhances the positivity of younger and older adults’ recall: support for socioemotional selectivity theory

Compared with younger adults, older adults have a relative preference to attend to and remember positive over negative information. This is known as the “positivity effect,” and researchers have typically evoked socioemotional selectivity theory to explain it. According to socioemotional selectivity theory, as people get older they begin to perceive their time left in life as more limited. These reduced time horizons prompt older adults to prioritize achieving emotional gratification and thus exhibit increased positivity in attention and recall. Although this is the most commonly cited explanation of the positivity effect, there is currently a lack of clear experimental evidence demonstrating a link between time horizons and positivity. The goal of the current research was to address this issue. In two separate experiments, we asked participants to complete a writing activity, which directed them to think of time as being either limited or expansive (Experiments 1 and 2) or did not orient them to think about time in a particular manner (Experiment 2). Participants were then shown a series of emotional pictures, which they subsequently tried to recall. Results from both studies showed that regardless of chronological age, thinking about a limited future enhanced the relative positivity of participants’ recall. Furthermore, the results of Experiment 2 showed that this effect was not driven by changes in mood. Thus, the fact that older adults’ recall is typically more positive than younger adults’ recall may index naturally shifting time horizons and goals with age

Idiosyncratic deals for older workers: increased heterogeneity among older workers enhance the need for i-Deals

The rapid aging of the workforce throughout the Western world and parts of Asia, including Japan and China, poses many challenges on contemporary organizations (European Commission, 2010 ; Wang & Shultz, 2010 ). The Babyboom generation, consisting of workers born between 1945 and 1965, constitutes a large part of the current workforce. Due to decreased fertility rates, there are fewer younger workers entering the labor market, as a consequence of which the percentage of older workers is rapidly increasing (Truxillo & Fraccaroli, 2013 ). Consequently, organizations are increasingly aware that the employee population is changing, and that strategies to employ, motivate, and retain workers have to be adapted accordingly. It is no longer suffi cient for organizations to focus on employing younger workers (e.g., through designing traineeships for graduates), because the infl ux of younger workers in the labor market is stagnating, which is in particular present in certain sectors, such as technical occupations and health care (Polat, Bal, & Jansen, 2012 ). Hence, organizations increasingly will have to rely on older workers, and try to retain older workers, and motivate them to stay longer in the workforce. Similarly, governments across Europe are also increasing offi cial retirement ages, and making it fi nancially less attractive for older workers to retire early (European Commission)

Antecedents and Outcomes of Managing Diversity in a UK Context: Test of a Mediation Model

Extant research on diversity management has primarily examined the main effects of diversity management practices on outcomes from an organizational perspective. Meta-analysis in this field corroborates the conclusion that this approach is unable to account for the outcomes of diversity management effectively. The current study extends the literature by examining organizational antecedents of diversity management practices (DMP). This study also examines the mediating influences of perception of overall justice (POJ) and social exchange with organization (SEWO) on the relationships between DMP and work outcomes of career satisfaction and turnover intention. Results of data obtained from a cross section of 191 minority employees in UK revealed: (i) the reasons why organisations adopted and implemented DMP influenced employees’ outcomes of turnover intention and career satisfaction; (ii) the relationship between diversity management and social exchange with organization is mediated by perception of overall justice; (iii) social exchange with organization relates to increased career satisfaction; and (iv) DMP related positively to career satisfaction through perception of overall justice and SEWO

Latest Cretaceous climatic and environmental change in the South Atlantic region

Latest Maastrichtian climate change caused by Deccan volcanism has been invoked as a cause of mass extinction at the Cretaceous-Paleogene (K-Pg) boundary (~66.0 Ma). Yet late Maastrichtian climate and ecological changes are poorly documented, in particular on the Southern Hemisphere. Here we present upper Maastrichtian-lower Danian climate and biotic records from the Bajada del Jagüel (BJ) shelf site (Neuquén Basin, Argentina), employing the TEX86 paleothermometer, marine palynology (dinoflagellate cysts), and micropaleontology (foraminifera). These records are correlated to the astronomically tuned Ocean Drilling Program Site 1262 (Walvis Ridge). Collectively, we use these records to assess climatic and ecological effects of Deccan volcanism in the Southern Atlantic region. Both the TEX86-based sea surface temperature (SST) record at BJ and the bulk carbonate δ18O-based SST record of Site 1262 show a latest Maastrichtian warming of ~2.5-4°C, at 450 to 150 kyr before the K-Pg boundary, coinciding with the a large Deccan outpouring phase. Benthic foraminiferal and dinocyst assemblage changes indicate that this warming resulted in enhanced runoff and stratification of the water column, likely resulting from more humid climate conditions in the Neuquén Basin. These climate conditions could have been caused by an expanding and strengthening thermal low over the South American continent. Biotic changes in response to late Maastrichtian environmental changes are rather limited, when compared to the major turnovers observed at many K-Pg boundary sites worldwide. This suggests that environmental perturbations during the latest Maastrichtian warming event were less severe than those following the K-Pg boundary impact
