AN EXPLORATORY STUDY OF SELF-LEADERSHIP IN PHYSICAL ACTIVITY SETTINGS

The present study aimed to investigate the perceived extent of competence of self-leadership as well as the extent to which the participants exercise self-leadership strategies in physical activities (competitive and recreational). Additionally, the existence of potential individual differences in gender- and form of physical activity-related self-leadership strategies. Three hundred seventy-three undergraduate students from a Greek university (n = 197 men, and n = 176 women) with age range were between 18–24 years (M = 20.12, SD = 2.35) participated. All participants participated in physical activities. They filled out a validated Greek version of the Revised Self-leadership Questionnaire (RSLQ). Results revealed that participants reported (a) some positive self-leadership tendencies and (b) higher scores in the strategies such as self-goal setting, natural rewards and self-talk. Additionally, the findings demonstrated that self-leadership strategies may interact with gender and type of physical activity.  Article visualizations

Fast Screening Method for the Assessment of Freight Demand at the Initial Planning Stage of a New Transport and Logistics Centers

This paper presents an empirical approach that allows pre-feasibility assessment of logistics infrastructure for defined locational and fleet constraints. It aims at developing a fast screening method for the assessment of demand of a public Transport and Logistics Center, which is important for properly selecting the Center’s size and minimising the risk of over or under-estimation of capacity needs. The results are useful for policy makers to facilitate the early planning and commercialisation phases of a TLC project. The method develops the appropriate cost functions in order to compare two logistics strategies: one that involves the use of TLC to achieve economies of scale, and another one that assumes direct deliveries from origin to destination to save time and handling costs. The method has been applied as a pilot study in a case of a regional Center in Greece, advocating its applicability and reusabilit

Experiences from active membership and participation in decision-making processes and age in moral reasoning and goal orientation of referees

Etude réalisée auprès de 148 arbitres de football, de basket-ball et de handball, âgés de 17 à 50 ans. Interaction entre l'engagement d'un grand nombre d'entre eux comme membres actifs ou comme dirigeants dans le milieu associatif au sein d'organisations sportives, culturelles ou politiques, leur maturité et les éléments de personnalité ou qualités psychologiques influant sur leur pratique d'arbitre : principes moraux (jugement, prise de décision en situation de dillemme moral), orientations motivationnelles..

Structure validity of the Three-Factor Eating Questionnaire-R18 in Greek population

The aim of the present study was to examine the factor structure of the TFEQ-R18. The project was conducted in Greek population; thus, the questionnaire was translated in Greek language. 495 males and females aged between 12-45 years old participated in the present study. There were used a series of CFA techniques for structure analysis. Confirmatory and exploratory analyses were conducted. Several criteria were used to test the hypotheses factor structures of the AIMS. The results of CFA’s showed that the R-18 item instrument had adequate psychometric properties for measuring three dimensions of eating behavior of the Greek population However these results evealed that an R-16 item instrument was better adapted to the Greek population. The present study provided encouraging preliminary evidence supporting selected psychometric properties of the TFEQ-R18. This instrument seems to be a valid measure of the tendencies of cognitive restraint, uncontrolled eating and emotional eating of Greek population

Pragmatic solutions to reduce the global burden of stroke: a World Stroke Organization–Lancet Neurology Commission

Stroke is the second leading cause of death worldwide. The burden of disability after a stroke is also large, and is increasing at a faster pace in low-income and middle-income countries than in high-income countries. Alarmingly, the incidence of stroke is increasing in young and middle-aged people (ie, age <55 years) globally. Should these trends continue, Sustainable Development Goal 3.4 (reducing the burden of stroke as part of the general target to reduce the burden of non-communicable diseases by a third by 2030) will not be met. In this Commission, we forecast the burden of stroke from 2020 to 2050. We project that stroke mortality will increase by 50%—from 6·6 million (95% uncertainty interval [UI] 6·0 million–7·1 million) in 2020, to 9·7 million (8·0 million–11·6 million) in 2050—with disability-adjusted life-years (DALYs) growing over the same period from 144·8 million (133·9 million–156·9 million) in 2020, to 189·3 million (161·8 million–224·9 million) in 2050. These projections prompted us to do a situational analysis across the four pillars of the stroke quadrangle: surveillance, prevention, acute care, and rehabilitation. We have also identified the barriers to, and facilitators for, the achievement of these four pillars. Disability-adjusted life-years (DALYs) The sum of the years of life lost as a result of premature mortality from a disease and the years lived with a disability associated with prevalent cases of the disease in a population. One DALY represents the loss of the equivalent of one year of full health On the basis of our assessment, we have identified and prioritised several recommendations. For each of the four pillars (surveillance, prevention, acute care, and rehabilitation), we propose pragmatic solutions for the implementation of evidence-based interventions to reduce the global burden of stroke. The estimated direct (ie, treatment and rehabilitation) and indirect (considering productivity loss) costs of stroke globally are in excess of US$891 billion annually. The pragmatic solutions we put forwards for urgent implementation should help to mitigate these losses, reduce the global burden of stroke, and contribute to achievement of Sustainable Development Goal 3.4, the WHO Intersectoral Global Action Plan on epilepsy and other neurological disorders (2022–2031), and the WHO Global Action Plan for prevention and control of non-communicable diseases. Reduction of the global burden of stroke, particularly in low-income and middle-income countries, by implementing primary and secondary stroke prevention strategies and evidence-based acute care and rehabilitation services is urgently required. Measures to facilitate this goal include: the establishment of a framework to monitor and assess the burden of stroke (and its risk factors) and stroke services at a national level; the implementation of integrated population-level and individual-level prevention strategies for people at any increased risk of cerebrovascular disease, with emphasis on early detection and control of hypertension; planning and delivery of acute stroke care services, including the establishment of stroke units with access to reperfusion therapies for ischaemic stroke and workforce training and capacity building (and monitoring of quality indicators for these services nationally, regionally, and globally); the promotion of interdisciplinary stroke care services, training for caregivers, and capacity building for community health workers and other health-care providers working in stroke rehabilitation; and the creation of a stroke advocacy and implementation ecosystem that includes all relevant communities, organisations, and stakeholders
