This study’s purpose was to provide additional psychometric data on the Computer Aversion, Attitudes, and Familiarity Index (CAAFI). The CAAFI is comprised of 40 items, yielding a total score and four factor scores with 10 items each (one familiarity, one attitudes, two aversion). The measure was administered to a sample of undergraduate psychology students (N = 293) along with the Computer Understanding and Experience Scale, the Computer Attitude Scale, and the Computer Aversion Scale. The factor structure of the CAAFI was supported via confirmatory factor analytic procedures and analysis of internal consistency reliability coefficients. In relation to the other measures of computer-related constructs, the strongest validity support was found for the CAAFI total score and Factors 1 (computer familiarity) and 3 (computer aversion-discomfort), followed by Factor 2 (computer attitudes). With regard to Factor 4 (computer aversion-fear), given the results of the analyses the decision was made to remove these items from the CAAFI in order to enhance the measure’s psychometric properties and practical utility.  相似文献

Using the example of a real product, this paper shows how various usability assessments, conducted by different human factors engineers, in several phases of the product's development life-cycle, identified similar potential usability problems. Circumstances dictated that no remedial action was taken, so it was possible to track these potential usability defects to customer sites, where it was found that most of the important problems did indeed occur. Thus, it can be demonstrated that human factors advice was valid and reliable. In simpler terms, early usability evaluation by human factors engineers can save hours of wasted development effort and customer frustration, and can help to ensure that a more usable product is produced.  相似文献

Electron elastic total cross sections (TCSs) and differential cross sections (DCSs) in both impact energy and scattering angle for the excited Au and Pt atoms are calculated in the electron impact energy range 0 ? E ? 4.0 eV. The cross sections are found to be characterized by very sharp long-lived resonances whose positions are identified with the binding energies of the excited anions formed during the collisions. The recent novel Regge-pole methodology wherein is embedded through the Mulholland formula the electron-electron correlations is used together with a Thomas-Fermi type potential incorporating the crucial core-polarization interaction for the calculations of the TCSs. The DCSs are evaluated using a partial wave expansion. The Ramsauer-Townsend minima, the shape resonances and the binding energies of the excited Au and Pt anions are extracted from the cross sections, while the critical minima are determined from the DCSs.  相似文献

Hurricane Katrina continues to capture attention and influence scholarship including official reports that focus more on event chronologies than on conceptual patterns. Our paper explores conceptual patterns crisis management behaviour, drawing upon Lalonde's (2004) archetypes of crisis managers as collectivists, integrators, and reactives. We add a paralytics archetype for our analysis. Key findings include an imbalance between counterproductive and constructive archetypes. Reactive and paralytic crisis manager behaviours were over‐represented, significantly contributing to conflict, communication failures, and the systemic failure of governments. Collectivist and integrator archetypes were badly under‐represented, limiting intergovernmental relations, cooperation, and communication embedded in these behaviour types. Crisis management performance with future crises would benefit from a systematic assessment of crisis management styles and behaviours.  相似文献

Treatment effects of a 12-wk day-treatment program were explored on measures of psychiatric distress (Brief Symptom Inventory) and maladaptive schemas (Schema Questionnaire Short Form; J. Young, 1990). 84 program completers (aged 22–57 yrs) showed significant pre–post change in psychiatric distress and on 3 of 15 schema: vulnerability to harm, social alienation, and defectiveness. Other schema did not change over the 12 wks. 15 waiting-list controls demonstrated no improvement in either distress level or in any of the 15 schema while waiting to be admitted to the program. Only 1 of the 15 schema, abandonment, predicted treatment outcome on changes in psychiatric distress level. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

A maternal high fat diet (HFD) can have adverse effects on skeletal muscle development. Skeletal muscle PLIN proteins (PLIN2, 3 and 5) are thought to play critical roles in lipid metabolism, however effects of HFD on PLIN and lipases (HSL, ATGL, CGI‐58) in mothers as well as their offspring have yet to be investigated. The primary objective of this study was to determine whether maternal HFD would influence skeletal muscle lipase and PLIN protein content in offspring at weaning (19d) and young adulthood (3mo). Female rats (28d old, n = 9/group) were fed control (CON, AIN93G, 7 % soybean oil) or HFD (AIN93G, 20 % lard) for 10 weeks prior to mating and throughout pregnancy and lactation. All offspring were weaned to CON [n = 18/group, 1 female and 1 male pup per litter were studied at weaning (19d) and 3mo of age]. There was no effect of sex for the main outcomes measured in plantaris, therefore male and female data was combined. Maternal HFD resulted in higher triacylglycerol content in pups at 3mo (p < 0.05), as well as in the dams (p = 0.015). Maternal HFD resulted in higher PLIN5 content in pups at weaning and 3mo (p = 0.05). PLIN2 and PLIN5 content decreased at 3mo versus weaning (p < 0.001). HFD dams had a higher PLIN3 content (p = 0.016). Diet had no effect on ATGL, CGI‐58, or HSL content. In conclusion, exposure to a maternal HFD resulted in higher skeletal muscle lipid and PLIN5 content in plantaris of offspring through to young adulthood.  相似文献
