Research has shown that inexperienced drivers underestimate the risks associated with a range of driving situations. In addition, personality factors are an important influence on both risk ...perceptions and driving behaviour. The study investigated the strength of relationship between personality factors, risk perceptions, and driving behaviour among young, mainly inexperienced drivers. One-hundred and fifty-nine students aged between 17 and 20 completed an online questionnaire assessing five facets of personality, four components of risk perceptions, and one measure of driving behaviour. Using structural equation modeling as a means of assessing the overall fit of each model, 39% of the variance in young drivers’ speeding was accounted for by Excitement-Seeking, Altruism, their Aversion to Risk Taking, and their own likelihood of having an accident, with Altruism and Aversion to Risk Taking both showing moderate negative relationships. Road safety interventions should examine whether they strengthen young drivers’ appreciation of the impact of their actions on others through positive reinforcement of altruistic norms.
To cope with demands of working while studying, students must structure the boundaries between these roles (e.g., integrate or segment them) to suit their preferences and circumstances. However, ...students differ on how well they do this, and we do not yet understand the factors that contribute to managing work and study well. We sought to determine if different student groups existed and if the groups reported different work, study, and wellbeing outcomes. Using latent profile analysis and assessing work-study boundary congruence and flexibility (
= 808; 76% female;
19.6 years), we identified four groups of (a) "balanced" (65.4%; with moderate boundary congruence and flexibility); (b) "high work congruence and flexibility" (17.5%; working arrangements supportive of study role); (c) "low work congruence and flexibility" (9.7%; unsupportive workplace arrangements); and (d) "low study congruence" (7.3%; study arrangements unsupportive of work role). These groups reported different work/study demands, role conflict, study burnout, and perceived employability, with "balanced" and "high work congruence and flexibility" groups scoring more positively and "low work congruence and flexibility" and "low study congruence" groups scoring more negatively. Results supported that different student groups existed, and these will need different supports to manage their multiple role responsibilities.
Mood profiling has been a popular assessment strategy since the 1970s, although little evidence exists of distinct mood profiles beyond the realm of sport and exercise. In the present study, we ...investigated clusters of mood profiles derived from the six subscales of the Brunel Mood Scale using the
website. Mood responses in three samples (
= 2,364,
= 2,303,
= 1,865) were analyzed using agglomerative, hierarchical cluster analysis, which distinguished six distinct and theoretically meaningful profiles. K-means clustering further refined the final parameter solution. Mood profiles identified were termed the iceberg, inverse iceberg, inverse Everest, shark fin, surface, and submerged profiles. Simultaneous multiple discriminant function analysis showed that cluster membership was correctly classified with a high degree of accuracy. Chi-squared tests indicated that the six mood profiles were unequally distributed according to the gender, age, and education of participants. Future research should investigate the antecedents, correlates and consequences of these six mood profile clusters.
The development of Hodgkin's lymphoma (HL) is a known complication in patients with human immunodeficiency virus (HIV) infection. Extranodal involvement, specifically primary bone marrow Hodgkin's ...lymphoma (PBMHL) is a rare manifestation that has been reported in HIV-positive patients and may represent a distinct entity from HIV-associated HL. We present a case of PBMHL presenting with hemophagocytic lymphohistiocytosis (HLH) in an HIV-positive patient. The 55-year-old male with HIV/AIDS presented with abdominal pain, diarrhea, and fever, leading to hospital admission. Despite initial treatment, he deteriorated, prompting re-admission and investigation revealing pancytopenia and elevated inflammatory markers, suggestive of HLH. Subsequent bone marrow biopsy unexpectedly revealed PBMHL. Treatment with HLH-directed therapy and the HLH-94 protocol resulted in significant clinical improvement. This case underscores the importance of recognizing atypical lymphoproliferative presentations in HIV/AIDS patients and the need for interdisciplinary collaboration in complex cases.
Ryff's (1989b) Psychological Well-Being (PWB) scales measure six related constructs of human functioning. The present paper examined the validity of Ryff's 6-factor PWB model, using data from a life ...events study (N = 401) and an organisational climate study (N = 679). Previous validation studies, using Confirmatory Factor Analysis (CFA), have identified alternative PWB models, but limitations include the use of shorter scale versions with items relating to a number of life domains within the same PWB factor, and failure to examine the influence of participants' socio-demographic characteristics on PWB. In this study, Exploratory Factor Analysis (EFA) mostly found consistency in the PWB items and structure between the two studies whereby a 3-factor model delineated between items relating to Autonomy, Positive Relations and a super-ordinate factor comprising the other PWB factors. Using CFA, Goodness of Fit indices reached acceptable levels for the adjusted PWB model identified by the EFA, whilst differences between adjusted models of PWB previously identified in the literature were hardly evident. Post-hoc analysis by gender demonstrated socio-demographic effects on the structure and items that comprise PWB. Further development of PWB measures is needed to reflect its hierarchical and multi-dimensional nature. In the scales' current form, the construct validation of the PWB factors will continue to be problematic and will fail to adequately evaluate the nature and impact of PWB.
The violation of aviation rules, particularly meteorological flight rules, can have fatal outcomes. Violation can sometimes be explained by intentional risk-taking, alternatively it can be the ...manifestation of a strategy to enhance performance and influence outcomes, such as saving time or fulfilling customer expectations. The aim of this study was to determine the types of risk-taking behavior within extant empirical research and identify multilevel antecedents related to risk-taking in the context of aviation operations, via a systematic literature review. 4,742 records were identified, which after screening resulted in the detailed consideration of 10 studies, three qualitative and seven quantitative studies, which met the eligibility criteria. Only published works were included in the review, thus the results may have been subject to publication bias, however, the types of risk taking within the research were consistent with that observed in Australian and New Zealand accident reports. The predominate risk-taking behavior was that of continuing Visual Flight Rules (VFR) flight into deteriorating conditions / Instrument Meteorological Conditions (IMC). Multilevel influences could be categorized under two overarching themes, being "continuation influence" and "acceptance of risk / normalization of deviance." One or both themes was consistently observed across the finding in all studies, although precaution should be given to the relative frequency of the reported associations. This review indicates the value of considering the social and organizational influences on risk-taking, and suggests avenues for future research, in particular exploring the influences through a Self-Determination Theory (SDT) lens.
The need to better understand the impact of changes in work conditions is paramount. While greater flexibility has considerable benefits, there may also be unintended consequences such as greater ...work intensification leading to poorer health and well-being. This research focuses on the unique variance in measures of well-being that is accounted for by work intensification, after accounting for the influence of working hours. The sample involved 391 participants who were employed at the time of the study. Using hierarchical multiple regression, we found that work intensification accounted for 7 percent of the unique variance in work-life integration and 5 percent of the unique variance in a measure of global life stress. In addition, our study provides evidence that work intensification operates to predict employee stress above and beyond the effects of work-life integration alone, while together both constructs account for 9 percent of the unique variance in a measure of global life stress. These results highlight the value of differentiating between different types of work demands and how these combine to predict employees' well-being. In order to achieve better work-life balance, we need to consider both the structural aspects of work such as working hours, place of work, and working conditions, as well as the pace of work.
This study focused on the impact of reemployment on access to both the latent and manifest benefits of employment, and mental health. Existing theories predicted that reemployment would positively ...affect these variables. One hundred and fifteen unemployed participants in South East Queensland, Australia, completed two paper‐and‐pencil surveys administered 6 months apart that included measures of financial hardship, financial strain, access to the latent benefits (collective purpose, social contact, status, activity, and time structure), and mental health (as measured by the 12‐item General Health Questionnaire). Participants who gained employment (N = 58) were better off financially, reported greater access to social contact and time structure and had significant improvements in their mental health at Time 2. Participants who remained unemployed showed no change over time. Whilst these results highlight that there is a strong positive impact of reemployment, it is acknowledged that the picture is much more complex than what we have reported here. We recommend that structured programmes be available before unemployment is experienced, particularly those that have a beneficial preventive effect on mental health among those participants most at risk of psychological disorders.
'Banks v. Goodfellow' 1870. LR 5 QB 549 (Eng.) is almost 150 years old, yet still stands as authority for the principle that unsoundness of the mind will not rebut testamentary capacity where it does ...not affect the will itself. Readers of this journal would know that psychology has advanced greatly during this sesquicentenary, and yet the law relating to testamentary capacity has remained relatively stagnant. We review the present laws relating to decision-making for adults with impaired capacity, particularly in Queensland, and also review various models of gauging decision-making capacity in other jurisdictions. We argue that qualified experts should be enlisted to make determinations about testamentary capacity when questions of capacity arise. We also argue the case for the development of scientifically validated protocols to assess decision-making capacity in the testamentary context.
