Vertex interactions and film shapes in two-dimensional foam

A model of the structure of two-dimensional foam (cells separated by circular arcs (films) meeting at threefold vertices) is considered. Films that are so curved as to be nearly semicircular arcs are problematic for conventional foam structure computations, which aim to identify the pressures needed to achieve specified bubble areas. When the films have near semicircularity, tiny variations in pressure can lead to large changes in the computed bubble area, and hence a failure to meet the specified targets. A new algorithm for determining foam structure is presented. It is based on 'freezing' most of the system, except the nearly semicircular arcs, and then finding the particular bubble pressures associated with the latter via an analytic approximation. This procedure is shown to work well for structure relaxation in a small bubble cluster. Large relaxed bubble clusters are considered briefly at the end of the paper.     

Influences of Creative Personality and Working Environment on the Research Productivity of Business School Faculty

Previous research on creative working environments has focused on business organizations. This study examined the influence of creative personality and creative working environment on the research productivity of business faculty. It was hypothesized that creative personality, family support, colleague support, research resources, and workload pressures would all have a positive association with research productivity. Management faculty people (N = 247) employed in business schools with a doctoral program participated in an online survey. Research productivity was assessed using both objective counts of journal publications across a 5-year period and self-report. Support from colleagues and workload pressures were positively associated with total self-reported publications. Research resources and workload pressures were positivly associated with publications in top management journals. Implications for future research and practice are discussed.     

Pinning down the problems and influences: Disordered eating and body satisfaction in male wrestlers

ObjectivesDisordered eating and body dissatisfaction are common concerns among athletes. However, these variables have been minimally explored in male wrestlers. Sociocultural influences can impact drive for muscularity, body satisfaction, and disordered eating, but it is unclear which influences are most prominent in this population. The present study had two aims: 1) examine the nature of drive for muscularity, body satisfaction, and disordered eating in collegiate wrestlers, and 2) investigate which sociocultural influence (general, coach/teammate, sport appearance pressures) most strongly predicts drive for muscularity, body satisfaction, and disordered eating.Methods and designThis study was cross-sectional. Participants included 103 National Collegiate Athletic Association Division I male collegiate wrestlers in the U.S. who completed surveys in season on sociocultural influences, drive for muscularity, body satisfaction, and disordered eating.ResultsWrestlers had a high drive for muscularity and engaged in many unhealthy behaviors to lose weight; however, they had relatively high body satisfaction. Relative weight analyses showed that sport appearance pressures were the strongest predictor of drive for muscularity while general pressures were the strongest predictor of body satisfaction and restricting eating behaviors.ConclusionsFindings suggests that disordered eating needs to be addressed among wrestlers and potential influences to target.     

Business owner-managers' descriptions of entrepreneurship: A content analysis

Abstract

Entrepreneurship is one of the most researched topics in business research. Findings have been mixed regarding the traits of entrepreneurs, and interest has grown in examining the behavioral aspects and business operations elements necessary for effective entrepreneurship, branching out from the focus on personality traits that has dominated the literature. We explored the area of entrepreneurship with the goal of developing a useful framework for viewing this domain. Content analysis was used to build the framework from business owner-managers' observations of entrepreneurial effectiveness. The construct categories and the overall dimensions and their relationships to entrepreneurship are reported. The result is the beginning of a process to describe an entrepreneurship system. Suggestions for future research and the continuation of entrepreneurship model development are offered.     

Euthanasia,Senicide, and the Aging Society

ABSTRACT

The elderly, particularly the severely demented, are at the cutting edge of the debate over active euthanasia. Such debilitated persons fall below the standards of “personhood” as these have been defined by various moral philosophers. With the pressures of economic hard times, one might predict that the most impaired aged would be candidates for “direct termination.” However, this essay defends the thesis that the prohibition against mercy killing must be upheld despite such pressures. It draws on the wisdom of both Hippocrates and Abraham.     

Can more business ethics teaching halt corruption in companies?

Abstract

This article deals with the question of whether an increased teaching of business ethics can/will have a positive effect on the fight against corruption in companies. It is written from a (South) African perspective. Statistics about the alarming state of corruption in South African businesses are provided in the beginning. A Hegelian approach to the problem, in terms of which theory can and does influence practice, is compared to a Marxist approach, in terms of which theory is only a reflection of practice. The author chooses a position that mediates between these two extremes. In the end, he develops a model that relies heavily on the idea of an ethics of responsibility that draws on Aristotle’s idea of phronesis (practical wisdom based on deliberation). The practical implications of these ideas for the utilization of business ethics teaching in companies are consequently spelt out. While more teaching of this discipline cannot guarantee better morals in a company, it can better equip all involved to deal with the ever-increasing moral problems that business people have to deal with.     

Phase transitions of Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass at pressures up to 27 GPa

The phase transitions of Zr_41.2Ti_13.8Cu_12.5Ni₁₀Be_22.5 bulk metallic glass have been investigated under high pressures and at room temperature. Direct resistance measurements in a diamond anvil cell provide evidence of a reversible transition between amorphous and crystalline phases; crystallization events occurred at 24 and 26.2 GPa on uploading, and crystalline-to-amorphous phase transitions were observed at 16 and 10.6 GPa on downloading. The phase transitions were confirmed by transmission electron microscopy observations.     

Human dignity and human rights in the philosophy of absolute idealism

The tides of change constantly surface new currents in the world of business. No longer is it sufficient to seek the static positional advantage offered by classical Porterian analysis. This article explores the emerging direction of business strategy as expressed by the concept of evolutionary advantage. It examines first the major forms of business knowledge over the last century, then considers mainstream frameworks for strategic analysis, and offers, as a compelling alternative, the emerging notions of evolutionary development and evolutionary learning. Through application of Evolutionary Systems Design, it is shown how an organization may cultivate strategies for sustainable success.     

Equity,Equality, and Need in the Adult Family

Abstract

British students were given scenarios about family and business situations and were asked to rate various cost allocation decisions in terms of fairness and justice, and conflict. In terms of fairness/justice, there was no difference between the need and equity allocations in the family situation, though equity was preferred in the business situation. The equality division was the least preferred in all situations, and equity was judged to be the division the least likely to evoke conflict in all situations.     

Performance Excellence: A Personal Perspective on the Link Between Sport and Business

This article provides a personal perspective on the link between excellence in sport and business. It traces the author's transition from sport psychologist to business consultant before identifying specific areas in which direct links can be drawn between the two domains. Specifically, five major areas are addressed: organizational issues, in which a demands, supports, constraints approach is outlined; stress, including a model of stress in leaders and a model of stress and coping; leadership, in which a model of leadership and how it relates to performance is presented; high-performing teams, based on a create, unite, perform (CUP) model of team building, team work, and team effectiveness; and one-to-one coaching/consulting, in which common areas across sport and business are identified. The general conclusion is that the principles of elite performance in sport are easily transferable to the business context, and also that sport has a considerable amount to learn from excellence in business.     

Norms regarding Drinking Behavior in the Business Environment

Abstract

American men and women employed in management and professional positions were asked to evaluate five drinking behaviors within a business context. Analysis of the results suggested the presence of norms prohibiting excessive drinking and permitting abstinence but the absence of norms instructing the drinker on appropriate ways to handle alcohol. Norms for women were less clear, possibly as a function of their newness to higher positions in business.     

When in doubt,it’s not out: Match format is associated with differences in elite-level cricket umpires’ leg-before-wicket decisions

ObjectivesContextual factors can influence the way sports officials apply unambiguous rules. The aim of this study was to better understand the leg-before-wicket (LBW) decision-making behaviour of elite cricket umpires and determine whether their behaviour changes according to the format of the game in which they are adjudicating.MethodsLBW decisions (n = 5578) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed using a signal detection paradigm. Umpire sensitivity (A) and response bias (B) were compared to chance performance in three formats of the game: Four-day, One-day, and T20. Mixed effects models assessed sensitivity and response bias differences between match types.ResultsUmpires were able to differentiate between “out” and “not out” appeals to a high standard but were conservative and had a bias to respond “not out” in all formats of the game. Umpires were less accurate in the shorter formats of the game, particularly T20 cricket and were also significantly more conservative in T20 compared to Four-day Matches.ConclusionsCricket umpires are conservative and are highly accurate LBW decision makers. However, differences in their judgments were associated with different match formats. The unique task goals and contextual pressures afforded by the shorter formats of the game, particularly T20, may account for the observed performance differences we see here.     

Integrating positive psychology applications into the EMDR Peak Performance protocol

IntroductionThis article describes an innovative Eye Movement Desensitization and Reprocessing (EMDR) protocol which applies the standard EMDR protocol, with modifications, to the reduction of performance anxiety and enhancement of skillful performance in higher functioning clients.ObjectiveThe intention was to compare a modified version of the standard EMDR protocol for the reduction of performance anxiety and the enhancement of performance.MethodThe method was applying the special EMDR protocol for peak performance with higher functioning clients. A further enhancement applied three empirically valid techniques drawn from the subfield of positive psychology.ResultsPublished case studies suggest that this special EMDR protocol aided an experienced commercial pilot in overcoming his avoidance and returning to the flight simulator following a failed proficiency check, and assisted an executive in managing his sense of failure following a significant business setback. Athletes preparing for competition have also found the protocol assists them in managing precompetition anxiety. A further enhancement is the application of three techniques drawn from positive psychology which the empirical research in this subfield of psychology suggests can further enhance the benefits of this protocol.ConclusionLimitations are discussed and recommendations for future research are outlined.     

The effect of autonomous and controlled motives on eating dysregulation: Implications for individuals classified as underweight,overweight or obese

IntroductionControlled and autonomous motivational factors from self-determination theory have previously been highlighted as key factors in eating regulation. The present study examined controlled motives as an overarching motivational factor in eating dysregulation and examined its effects on dieting behaviour for those who are underweight, overweight or obese.ObjectiveTo examine whether the influence of controlled motives on dieting behaviour would be moderated by body mass index (BMI). Specifically, it was hypothesised that controlled motives would be associated with high levels of dieting behaviour in underweight individuals and low levels of dieting behaviour in individuals classified as overweight or obese.MethodOne hundred and thirty-seven participants completed the measures of height, weight, and motivation and intentions towards watching their diet and subsequently completed a measure of dieting behaviour two weeks later.ResultsModerated regression and simple slopes analyses provided support for the hypothesised effects at underweight, overweight, and obese range BMIs.ConclusionThe effect of controlled motives on dieting behaviour is dependent upon BMI and therefore varies across underweight, overweight, and obese individuals. The implications of controlled motives and external pressures to watch one's diet are discussed.     

Introduction to special issue on burnout and health

Abstract

In recent years, the issue of occupational stress and burnout have received increasing research attention. Given the amount of time people spend on work-related activities and the central importance of work to one's sense of identity and self-worth, it is not surprising that occupational stress is regarded as a central area of study. Although burnout is linked to the extensive literature on occupational health, burnout goes beyond occupational health by focusing on specific stressors in the workplace to emphasize total life and environmental pressures affecting health.     

The Evolution of Business: Learning,Innovation, and Sustainability in the Twenty-First Century

This article-as part of a broader evolutionary inquiry toward human fulfillment, societal wellbeing, and environmental sustainability-explores new frontiers for business. In a rapidly changing global environment, corporations can become evolutionary change agents for the creation of a sustainable global civilization by fostering financial, social, and environmental results. The contemporary metaphors used to describe the business world can be limited in times when an emergent paradigm calls for new visions and actions. An evolutionary understanding, grounded in evolutionary systems theory, can open possibilities for leadership and innovation toward sustainability. Complex systems, such as organizations, need to learn to learn in harmony with the dynamics of their milieu in order to co-evolve and create value. The paper concludes with a reflection on the implications of the evolutionary paradigm for business education.     

Postural Stability in Children with High Sacral Level Spina Bifida: Deviations from a Control Group

Abstract

Objective: To assess static and dynamic postural stability changes in children with high sacral level spina bifida.

Methods: Thirty-five children with high sacral level spina bifida and 35 age-matched healthy controls were enrolled. Their lower extremity muscle strengths and static and dynamic postural stability parameters were measured with the use of a dynamometer and the NeuroCom Balance Master^® device, respectively. Functional gait and balance were evaluated using the five times sit-to-stand test (5STS) and the 6-minute walk test (6MWT). Spinal, hip, and ankle deformities of the patient group were measured by radiologic evaluation.

Results: In comparison with controls, patients were found to have lower ankle dorsiflexion and plantar-flexion strength, increased 5STS duration, and decreased 6MWT distance while both static and dynamic postural stability parameters were significantly different. Bilateral ankle muscle strengths were found to be negatively correlated with postural stability parameters. The presence of hydrocephalus or meningomyelocele in the patient group was found to have negative effects on static postural stability.

Conclusion: Static and dynamic postural stability is affected even in children with high sacral level spina bifida who are expected to have best condition in this patient population. The ankle muscle strength is the main factor influencing these changes.     

The surface energy of strained foam clusters

We derive general equations relating the surface energy of strained bubble clusters to the volumes and pressures in the bubbles. These equations generalize a similar equation for free bubble clusters. We apply the equations to periodic clusters, clusters between two parallel walls and clusters enclosed by a wall.     

A Comparative Analysis of Sport and Business Organizations: Factors Perceived Critical for Organizational Success

The purpose of the present investigation was to compare and contrast sport and business leaders' perceptions regarding what makes for a successful organization. Twenty sport ( N = 10) and business ( N = 10) leaders were interviewed and asked about their perceptions of organizational effectiveness in the area of group dynamics including (a) leadership, (b) group cohesion, and (c) communication. Using qualitative methods, results revealed more similarities than differences, with most sport and business leaders in agreement on the factors relating to organizational success. Specifically, all higher- and lower-order themes were identified by leaders in both areas, the emphasis simply being a matter of degree. Some of the more notable differences included business leaders putting more emphasis on being honest and being a reflective listener, whereas sport leaders emphasize interactions with others and having positive reinforcement in their communications. These similarities and differences are discussed in terms of the extant literature, and future directions for research are offered, such as investigating how to specifically enhance the transfer of skills and principles between sport and business settings.
