Generating Recommendations for Simulator Design Through Pilot Assessment of Prototype Utility

Incorporated in a simulator design project, this study assessed the utility of a simulator prototype for air combat training to optimize continued development. After several scenarios, the 13 male participants completed a survey. Seven fidelity levels: visual feedback, head-up/head-down, instrumentation, flight controls, graphics, visual resolution, and field-of-view were rated for three dimensions: realism, limitation of performance, and importance of realism. The results informed decisions about which fidelity levels, head-up/head-down and field-of-view, that should be prioritized during the next design cycle, and generated recommendations for continued simulator design and directives for further evaluations.     

Outcome expectations and work design characteristics in post-retirement work planning

Today, a growing number of individuals decide to work beyond normal retirement age (Eurofound, 2012). Research has revealed influencing factors for post-retirement work at the individual, job and organizational, family, and socioeconomic levels. However, not much is known about post-retirement work planning and its antecedents. The purpose of this study is to examine the effects of outcome expectations regarding post-retirement work and two work design characteristics (i.e., physical demands and social support at work) on post-retirement work planning by applying the framework of social cognitive career theory (SCCT; Lent, Brown, & Hackett, 1994). Data from 1065 employees of a German logistics company were used in this study. Results provide support for SCCT to be a suitable theoretical framework for understanding post-retirement career planning and thereby expand the application of SCCT to a new field. Furthermore, multilevel analysis revealed that physical demands were negatively related to the intention to continue to work for the pre-retirement employer after retirement entry, whereas social support at work strengthened the relationship between outcome expectations and same-employer-post-retirement work intention. Organizations who want their retired employees to continue to work in retirement should develop interventions to strengthen post-retirement work outcome expectations. An increase in social support at work as well as a reduction in physical demands may also contribute to increased participation in continued work with the same employer in retirement.     

Reid's Third Argument for Moral Liberty

Thomas Reid uses the term ‘moral liberty’ to refer to a kind of free will that is agent-causal and incompatible with determinism. I offer and textually support a new interpretation of Reid's third argument for moral liberty, which Reid presents in Section 4.8 of Essays on the Active Powers of Man. Generally regarded as obscure, most commentators either ignore Reid's third argument or lend it cursory attention. In my interpretation, Reid points to the truism that we have reason to think that human persons conceive of long-term plans. Then, Reid argues that determinism implies that God both conceives of and enacts these plans, leaving us without any reason to believe that people even conceive of these plans. Therefore, we should hold onto the truism and reject determinism. On my interpretation, Reid employs the premises of a theistic argument from design as premises of his argument.     

Redesigning work through idiosyncratic deals

This study links idiosyncratic deals (i-deals) to job design theory. It investigates the impact of individually negotiated job changes on performance, self-efficacy, and psychological strain through their intervening effects on work design. Based on a sample of 187 health care professionals employed by a hospital in Germany, three types of work design-related i-deals were investigated: (1) task, (2) career, and (3) flexibility i-deals. Consistent with hypotheses, the three types of i-deal had differential effects on work characteristics, and each in turn related to different outcomes. Specifically, job autonomy mediated the task i-deals—job performance relationship; skill acquisition mediated the career i-deals—occupational self-efficacy relationship; and reduced work overload mediated the flexibility i-deals—emotional and affective irritation relationships. Leader–Member Exchange was confirmed as an antecedent of all three types of i-deals. Task, career, and flexibility i-deals are discussed as ways to make work more intrinsically motivating, ensure one’s professional advancement, and balance workplace stressors.     

Influences on life aspirations among adolescents in a low-income community in Cape Town,South Africa

The aim of this study was to determine the influences on adolescents’ aspirations from a low-income community in Cape Town. A sequential mixed method exploratory design was used following two distinct phases. The qualitative phase comprised focus group interviews with 118 grade 12 learners attending a school in a low-income community (age range: 16–19 years) and focused on identifying factors influencing life aspirations. The quantitative phase with 191 adolescents (males?=?54.45 %, females?=?45.55 %); age range: 14–18 years) from the same community aimed to ascertain the influences of personal attributes on self-aspirations. Participants completed the Expectations/Aspirations measure, the New General Self-Efficacy Scale, the Rosenberg Self-Esteem Scale and the Multidimensional Scale of Perceived Social Support. Qualitative data were thematically analysed. Quantitative data were analysed using multiple regression. The findings revealed that self-efficacy, self-esteem and social support were the most critical factors influencing adolescents’ aspirations. Self-efficacy was a major determinant of life aspirations among the adolescents. Life skills programmes with youth from disadvantaged communities should seek to incorporate training aimed at developing adolescents’ self-efficacy.     

The Impact of Life Design Counselling on Adolescents

This study records a process of heightening self-awareness within a semi-structured ‘life design counselling’ process. The research was conducted on the basis of a case study designed to facilitate co-constructive conversation with a purposefully selected youth. The participant was enabled to reconstruct a preferred and meaningful future that could change as different experiences, challenges and needs arose. The study suggested that the postmodern techniques that were implemented enhanced the involvement of the participant in the study. The participant revealed heightened self-insight into his personal experiences, a ‘changed’ attitude to certain aspects of his life context and pro-active behaviour with regard to the challenges he was facing. We (the researchers) concluded that life design counselling could be a promising strategy that could have a lasting effect on adolescents.     

What is A Philosophical Question?

There are many ways of understanding the nature of philosophical questions. One may consider their morphology, semantics, relevance, or scope. This article introduces a different approach, based on the kind of informational resources required to answer them. The result is a definition of philosophical questions as questions whose answers are in principle open to informed, rational, and honest disagreement, ultimate but not absolute, closed under further questioning, possibly constrained by empirical and logico‐mathematical resources, but requiring noetic resources to be answered. The article concludes with a discussion of some of the consequences of this definition for a conception of philosophy as the study (or “science”) of open questions, which uses conceptual design to analyse and answer them.     

Mental health among people with psoriasis undergoing patient education in climate therapy

This study investigated the mental health of people with psoriasis undergoing patient education in climate therapy. A prospective design included a baseline assessment and two follow‐ups after a 3‐week patient education program. Participants were 254 adults. Positive mental health was measured by the mental health continuum short form (0–70), and negative mental health by the emotional distress subscale (1–4) of the health education impact questionnaire. Paired‐samples t‐tests were used to evaluate changes in mental health from baseline to follow‐up. Multiple linear regression was used to analyse the ability of socio‐demographic and clinical variables and emotional distress to predict changes in positive mental health. To predict change in negative mental health we repeated the same analysis but with a change in negative mental health as a dependent variable and positive mental health as an independent variable. The results show that positive mental health and health‐related emotional distress improved significantly from before to after the intervention by 7.1 points, p < 0.001 and 0.21 points, p < 0.001) respectively. At the second follow‐up, health‐related emotional distress remained significantly improved compared with baseline levels by 0.11 points, p = 0.004. The longer participants had lived with psoriasis ( β = 146, p = 0.027), and the presence of co‐morbid health problems (β  =  111, p = 0.051) the greater the improvement in the positive mental health immediately after the intervention. No predictors were identified for negative mental health. This study indicates that the promotion of positive mental health needs to be integrated into the climate therapy program, and sustained in their home context.     

Is the impaired N170 print tuning specific to developmental dyslexia? A matched reading-level study with poor readers and dyslexics

Left N170 print tuning has been associated with visual expertise for print and has been reported to be impaired in dyslexics, using age matched designs. This is the first time N170 print tuning has been compared in adult dyslexics and adult poor readers, matched in reading level. Participants performed a lexical decision task using both word-like stimuli and symbol strings. In contrast to dyslexics, poor readers displayed similar N170 tuning to control expert readers, suggesting that impaired N170 specialization is a hallmark of developmental dyslexia. Our findings provide electrophysiological support for dyslexia being the result of abnormal specialization of the left occipito-temporal areas involved in the expert processing of print. Furthermore, as shown by correlations data and in accordance with the phonological mapping deficit theory, the impaired visual expertise for print described in dyslexics may have been caused by their core phonological deficits.
