Individual Differences in the Experience of Cognitive Workload

This study investigated the roles of four psychosocial variables – anxiety, conscientiousness, emotional intelligence, and Protestant work ethic – on subjective ratings of cognitive workload as measured by the Task Load Index (TLX) and the further connections between the four variables and TLX ratings of task performance. The four variables represented aspects of an underlying construct of elasticity versus rigidity in response to workload. Participants were 141 undergraduates who performed a vigilance task under different speeded conditions while working on a jigsaw puzzle for 90 minutes. Regression analysis showed that anxiety and emotional intelligence were the two variables most proximally related to TLX ratings. TLX ratings contributed to the prediction of performance on the puzzle, but not the vigilance task. Severity error bias was evident in some of the ratings. Although working in pairs improved performance, it also resulted in higher ratings of temporal demand and perceived performance pressure

Feeling the future: A meta-analysis of 90 experiments on the anomalous anticipation of random future events

In 2011, one of the authors (DJB) published a report of nine experiments in the Journal of Personality and Social Psychology purporting to demonstrate that an individual\u2019s cognitive and affective responses can be influenced by randomly selected stimulus events that do not occur until after his or her responses have already been made and recorded, a generalized variant of the phenomenon traditionally denoted by the term precognition. To encourage replications, all materials needed to conduct them were made available on request. We here report a meta-analysis of 90 experiments from 33 laboratories in 14 countries which yielded an overall effect greater than 6 sigma, z = 6.40, p = 1.2 7 10 with an effect size (Hedges\u2019 g) of 0.09. A Bayesian analysis yielded a Bayes Factor of 5.1 7 10 , greatly exceeding the criterion value of 100 for \u201cdecisive evidence\u201d in support of the experimental hypothesis. When DJB\u2019s original experiments are excluded, the combined effect size for replications by independent investigators is 0.06, z = 4.16, p = 1.1 7 10 , and the BF value is 3,853, again exceeding the criterion for \u201cdecisive evidence.\u201d The number of potentially unretrieved experiments required to reduce the overall effect size of the complete database to a trivial value of 0.01 is 544, and seven of eight additional statistical tests support the conclusion that the database is not significantly compromised by either selection bias or by intense \u201cp -hacking\u201d\u2014the selective suppression of findings or analyses that failed to yield statistical significance. P-curve analysis, a recently introduced statistical technique, estimates the true effect size of the experiments to be 0.20 for the complete database and 0.24 for the independent replications, virtually identical to the effect size of DJB\u2019s original experiments (0.22) and the closely related \u201cpresentiment\u201d experiments (0.21). We discuss the controversial status of precognition and other anomalous effects collectively known as psi

RECRUITMENT AND SELECTION SYSTEM OF VILLAGES IN WONOSOBO REGENCY

Basic track problems in most of the villages in Wonosobo Regency Government are the recruitment and selection practices of other villages have not been able to encourage the inception of the village with the required standards of competence. This research aims to analyze the system of recruitment and selection of other villages, supporters and restricting factors, as well as establishing a proper and contextual model in Wonosobo Regency over the approach to the management of human resources. With descriptive method, this study found that the standard of competence has not been a consideration for the Government since the beginning of the planning process, to recruitment and selection. Almost the entire selection process, starting from the determination of the criteria of candidates, selection of administration until the written exams tend not based on competence. In addition, the necessary of the village according to the preference of the villagers also has yet to be fulfilled, thus still encountered complaints from the public. The study also identifies some of the factors supporting the recruitment and selection competency-based, among others, regulation and community support. Later, inhibitor factor, among others, the quality of human resources and organizational needs analysis Committee. Based on these conditions, the model recommendations in this study encourages the process of recruitment and selection apply competency — based in practice, in order to be able to support organizational performance towards the village government is better. Start the process of sourcing, attracting, through screening, based on the needs the competence and analyzed scientifically. Community preference is also a consideration in that process in order to involve the public opinion and build public confidence to the results of the selection. These two factors also continue to support are encouraged to be optimal. Meanwhile, an inhibitor of factor continues to be minimized through a variety of innovations

Impact Factor: outdated artefact or stepping-stone to journal certification?

A review of Garfield's journal impact factor and its specific implementation as the Thomson Reuters Impact Factor reveals several weaknesses in this commonly-used indicator of journal standing. Key limitations include the mismatch between citing and cited documents, the deceptive display of three decimals that belies the real precision, and the absence of confidence intervals. These are minor issues that are easily amended and should be corrected, but more substantive improvements are needed. There are indications that the scientific community seeks and needs better certification of journal procedures to improve the quality of published science. Comprehensive certification of editorial and review procedures could help ensure adequate procedures to detect duplicate and fraudulent submissions.Comment: 25 pages, 12 figures, 6 table

Children exposed to intimate partner violence: Identifying differential effects of family environment on children\u27s trauma and psychopathology symptoms through regression mixture models

The majority of analytic approaches aimed at understanding the influence of environmental context on children\u27s socioemotional adjustment assume comparable effects of contextual risk and protective factors for all children. Using self-reported data from 289 maternal caregiver-child dyads, we examined the degree to which there are differential effects of severity of intimate partner violence (IPV) exposure, yearly household income, and number of children in the family on posttraumatic stress symptoms (PTS) and psychopathology symptoms (i.e., internalizing and externalizing problems) among school-age children between the ages of 7–12 years. A regression mixture model identified three latent classes that were primarily distinguished by differential effects of IPV exposure severity on PTS and psychopathology symptoms: (1) asymptomatic with low sensitivity to environmental factors (66% of children), (2) maladjusted with moderate sensitivity (24%), and (3) highly maladjusted with high sensitivity (10%). Children with mothers who had higher levels of education were more likely to be in the maladjusted with moderate sensitivity group than the asymptomatic with low sensitivity group. Latino children were less likely to be in both maladjusted groups compared to the asymptomatic group. Overall, the findings suggest differential effects of family environmental factors on PTS and psychopathology symptoms among children exposed to IPV. Implications for research and practice are discussed

Narrative Health Communication and Behavior Change: The Influence of Exemplars in the News on Intention to Quit Smoking.

This study investigated psychological mechanisms underlying the effect of narrative health communication on behavioral intention. Specifically, the study examined how exemplification in news about successful smoking cessation affects recipients\u27 narrative engagement, thereby changing their intention to quit smoking. Nationally representative samples of U.S. adult smokers participated in 2 experiments. The results from the 2 experiments consistently showed that smokers reading a news article with an exemplar experienced greater narrative engagement compared to those reading an article without an exemplar. Those who reported more engagement were in turn more likely to report greater smoking cessation intentions

Repository Interface for Overlaid Journal Archives: costs estimates and sustainability issues

The RIOJA project (http://www.ucl.ac.uk/ls/rioja) investigated the feasibility of an overlay journal model in collaboration with the arXiv and in the scientific domain of astrophysics and cosmology. Scientists in this community are active users of e-prints repositories such as the arXiv. Furthermore, they have the support of Professional Associations and Learned Societies that have been pioneers in adapting to new publishing models and in particular electronic journals. Long term access to information as well as maintaining provision to sustainable systems/services is important to various parties in the scholarly communication system: the creators of information, developers and managers of services, libraries, publishers, funders and also users. Although scientific journals have been in existence since the 18th century (Lawal, 2001), factors such as increased journal subscription prices in the last decades and the emergence of new technologies have triggered discussions on the potential of new business models for publishing research. Furthermore, the advent of the open access movement also contributed to exploration of the issues around free access to information and provision of sustainable services. Exploring aspects of sustainability is something that should be seen over a period of time and whether launching, converting or simply maintaining a new or existing system/service the needs of the community it serves should be taken into account. Scientific journal publishing is a complex process. Besides disseminating scientific knowledge, registration of a claim for new discovery and a quality “stamp” it also facilitates social factors. Besides making research findings available and contributing to the advancement of knowledge, publishing is also a means for measuring quality of the work of scientists, allocating funding, and acknowledging contributions to knowledge. In this report, we will try to provide an overview of a new publishing model, that of the overlay journal. We will discuss the use of the arXiv by scientists in astrophysics and cosmology as well as the role of professional associations and learned societies in the publishing process for this community. We will briefly explain the methods employed to compile this report. We will also briefly present the RIOJA toolkit before we try and identify costs in the publishing process associated with the functions of registration, certification, and awareness and archiving. This report does not aim to provide a comprehensive report of actual journal publishing costings. Despite the fact that there are studies in existence that tried to document costs associated with journal publishing, the information presented there rarely corresponds to the actual costs of individual journal functions. In addition, the interviews with publishers and editors did not reveal any substantial information about costings that have not already been reported in the literature or are available on some publishers' websites. Where appropriate, this report aims to acknowledge studies conducted previously as pointers to further reading and, where applicable, to compare reported findings to observations made during the development and implementation of the RIOJA toolkit (described below). We will conclude this report with some of the issues reported in the literature around sustainability of services and some brief suggestions for further work
