The Relationship between Adult Students' Instructional Technology Competency and Self-Directed Learning Ability in an Online Course

The main purpose of this research was to examine the relationship between adult students' self-directed learning (SDL) ability and instructional technology (IT) competency in an online course. The study also investigated motivation and learning strategies that the students used to learn IT. The research involved surveying 198 continuing education professionals who took online courses at a large Midwest state university. The results indicate a statistically significant positive correlation between SDL ability and IT competency in students with above average SDL ability. The results also indicate that motivation is an important factor for learning technology in an online course regardless of the students' SDL ability. Additionally, the results show that students with higher level of SDL ability are likely to exhibit higher level of self-efficacy for learning and performance, and higher level of effort regulation.     

Developing a factor model of coal miners’ attributions on risk-taking at work

This paper details a survey of coal miners’ views on the bases for risk-taking. While literature exists on the subject of risk-taking in mines, comparatively few studies have sought to elicit the views of mine personnel themselves. An 83-item questionnaire, grounded upon insights from an earlier qualitative study, was developed and distributed to a sample of mine personnel (N=932). Results were analysed by means of principal components, factor analysis, an iterative refinement of the data set resulting in the development of a three-factor model that was considered to reflect potentially important dispositional influences on risk-taking amongst operational staff in mines. Derived constructs, identified as time pressure, management commitment and confidence in ability to control risk, were found to possess moderate to high levels of internal consistency (α statistic) and high face validity. Findings are discussed with reference to insights from both cognitive risk research and more recent work within the safety culture/climate framework.     

Sources of occupational stress: An examination of British prison officers

Abstract

The purpose of this paper is to identify the major sources of occupational stress experienced by British prison officers and to examine their effects on overall job stress and job satisfaction. Eighty-one officers from HM Prison, Maidstone, took part in a questionnaire study, and three main findings emerged. First, lack of stiff and resources were ranked as the most likely sources of stress, and areas of the prison where confrontations with inmates were most likely to occur were ranked as the most stressful locations. Second, officers who reported the highest levels of job stress overall had the lowest job satisfaction and the greatest wish for more emphasis on control and security of inmates. Third, when the sources of stress were factor-analysed and used to predict overall job stress and job satisfaction, using multiple regression, the sìngle most important predictor of job stress was found to be the factor labelled 'confrontations with inmates' and, for dissatisfaction with the job, it was 'poor morale and resentments'. The paper discusses the theoretical implications of the findings.     

Sleep hygiene practices and sleep duration in rotating-shift shiftworkers

Abstract

Alcohol, caffeine and tobacco intake, exercise, activities on going to bed, and sleep-enhancing measures were assessed in 72 rotating-shift shiftworkers to determine whether these variables differ following day shifts and night-shifts, and which are related to sleep duration. Only alcohol intake and exercise prior to sleep, and feeling drowsy when retiring, differed following the night-shift. Workers generally followed recommendations concerning alcohol intake, sleeping immediately on retiring, and exercising, but acted contrary to recommendations concerning caffeine and nicotine intake. The only behaviour clearly associated with poor sleep was smoking, which reduced sleep duration.     

Neuroticism,locus of control,type A behaviour pattern and occupational stress

Abstract

The aim of this study was to investigate the relationship between individual differences in personality and susceptibility to stress in the workplace. Stress in lecturers employed by a computer training organization was assessed by means of self-report and measurement of salivary cortisol output during lecturing and non-lecturing weeks. Neuroticism, Type A behaviour pattern and locus of control were measured. Self-reported stress was found to be much greater during lecturing weeks, but cortisol levels were unaffected by working conditions. There was a significant positive correlation between neuroticism and locus of control and a negative correlation between locus of control and Type A behaviour pattern that approached significance. Multiple regression was employed to explore relations between personality and stress. Subjects with lower neuroticism scores yielded a bigger increase in reported stress, in the lecturing compared with the non-lecturing week, than subjects with high neuroticism scores. Type B subjects showed a progressive decrease in cortisol over the working week while Type A counterparts showed a resurgence of cortisol towards the end of the week. Finally, Type B subjects having an internal locus of control showed a faster decline in cortisol level during the lecturing week than the other subjects. Implications of these results are discussed in terms of the importance simultaneously incorporating a variety of individual differences in personality dimensions and stress indices in research designs.     

Psychometric and Demographic Predictors of the Perceived Risk of Terrorist Threats and the Willingness to Pay for Terrorism Risk Management Programs

A 2009 national telephone survey of 924 U.S. adults assessed perceptions of terrorism and homeland security issues. Respondents rated severity of effects, level of understanding, number affected, and likelihood of four terrorist threats: poisoned water supply; explosion of a small nuclear device in a major U.S. city; an airplane attack similar to 9/11; and explosion of a bomb in a building, train, subway, or highway. Respondents rated perceived risk and willingness to pay (WTP) for dealing with each threat. Demographic, attitudinal, and party affiliation data were collected. Respondents rated bomb as highest in perceived risk but gave the highest WTP ratings to nuclear device. For both perceived risk and WTP, psychometric variables were far stronger predictors than were demographic ones. OLS regression analyses using both types of variables to predict perceived risk found only two significant demographic predictors for any threat—Democrat (a negative predictor for bomb) and white male (a significant positive predictor for airline attack). In contrast, among psychometric variables, severity, number affected, and likelihood were predictors of all four threats and level of understanding was a predictor for one. For WTP, education was a negative predictor for three threats; no other demographic variables were significant predictors for any threat. Among psychometric variables, perceived risk and number affected were positive predictors of WTP for all four threats; severity and likelihood were predictors for three; level of understanding was a significant predictor for two.     

Evaluation of the Service Review Model With Performance Scorecards

The current study combined a management technique termed “Service Review” with performance scorecards to enhance staff and consumer behavior in a human service setting consisting of 11 supervisors and 56 front-line staff working with 9 adult consumers with challenging behaviors. Results of our intervention showed that service review and scorecards produced significant staff behavior changes that were maintained over time. Positive consumer outcomes were also correlated with staff performance changes. The behavioral package of training, clinical consultation, service review, biweekly manager meetings, scorecards, and public posting has the potential to reduce the need for monetary staff incentives.     

International Experience in International Business Research: A Conceptualization and Exploration of Key Themes

International experience, the experience that firms accrue from operating internationally, is a key concept in explaining firm internationalization. This paper reviews the conceptualization of international experience in the international business literature. It highlights how prior research has identified three dimensions of the international experience construct (length, scope and diversity), thereby demonstrating that international experience should be treated as a multidimensional construct. In addition, intensity is presented as a fourth and novel dimension of international experience. The importance of this multidimensional conceptualization is highlighted in an explanation of why the international diversification and international experience constructs are not synonymous. In light of the importance of international experience in explaining firm internationalization, the authors explore how the source of the firm's international experience will determine the limits to its application in foreign markets. In particular, the authors distinguish between location‐bound international experience and non‐location‐bound international experience as sources of firm‐specific advantages (FSAs). The FSAs that the firm develops from its experience with equity and non‐equity entry modes are presented as examples of specific FSAs developed within the firm's bundle of FSAs concerning internationalization. The paper concludes with some implications of the conceptualization of international experience for several issues of international business research as well as providing managerial implications.     

Stakeholders’ Perspective on Ecological Modeling in Environmental Risk Assessment of Pesticides: Challenges and Opportunities

The article closely examines the role of mechanistic effect models (e.g., population models) in the European environmental risk assessment (ERA) of pesticides. We studied perspectives of three stakeholder groups on population modeling in ERA of pesticides. Forty‐three in‐depth, semi‐structured interviews were conducted with stakeholders from regulatory authorities, industry, and academia all over Europe. The key informant approach was employed in recruiting our participants. They were first identified as key stakeholders in the field and then sampled by means of a purposive sampling, where each stakeholder identified as important by others was interviewed and asked to suggest another potential participant for our study. Our results show that participants, although having different institutional backgrounds often presented similar perspectives and concerns about modeling. Analysis of repeating ideas and keywords revealed that all stakeholders had very high and often contradicting expectations from models. Still, all three groups expected effect models to become integrated in future ERA of pesticides. Main hopes associated with effect models were to reduce the amount of expensive and complex testing and field monitoring, both at the product development stage, and as an aid to develop mitigation measures. Our analysis suggests that, although the needs of stakeholders often overlapped, subtle differences and lack of trust hinder the process of introducing mechanistic effect models into ERA.
