This paper deals with the learning needs of Health Care Workers (HCWs) in the field of HIV/ AIDS. Essentially the paper covers their perceived initial education and training needs at tertiary level through to the continuing vocational professional development of HCWs who are involved in the practice of health care of people living with HIV/AIDS. The focus of the paper provides an illustration of the theme of adult education that searches for roles of social relevance in both a community and continuing professional setting, notably in the context of challenging human needs. In this illustration, the identification of the tertiary level education and training needs of HCWs by the practitioners themselves, as well as other interested stakeholders, is designed to help others who follow them practice with competence and confidence in this complex area of human need. Ultimately the continuing education of HCWs in such a challenging context is concerned with empowering people living with HIV/AIDS to come to realistic and positive terms with their condition.  相似文献

In this paper, we describe how and why we adopted a socially critical orientation to early career teacher resilience. In re-conceptualising early career teacher resilience, we expose the normative components of resilience by revealing the implicit values, beliefs and assumptions that underpin most traditional conceptions of resilience. We argue against the hyper-individualisation of the concept because it leads to a diminution of the influence of situational and structural forces on early career teachers’ experiences, and shifts primary responsibility for early career teacher well-being onto the individual. We lay the groundwork for a critical perspective on teacher resilience capable of illuminating the ‘problems’ of early career teachers within a broader social, cultural and political context. Our analysis is designed to promote further debate about new ways of seeing early career teacher resilience with the aim of creating and sustaining a spirit of optimism and human agency, as well as a sense of health and well-being among early career teachers.  相似文献

Although there are several reasons to predict that intellectually gifted children have different attitudes toward, experiences with, and opportunities for competition, the research literature on this topic is extremely limited. In this article, we review the literature and discuss an important distinction between task‐oriented competitive behavior, which is motivated by a desire to improve performance, and other‐referenced competitive behavior, which is motivated primarily by a desire to outdo an opponent. The implications of these competitive styles with regard to the academic achievement and social adjustment of gifted youngsters is explored and some suggestions for educators and parents are provided.  相似文献

Editorial     
In this paper, the scientific literature and that on the sports sciences relevant to javelin throwing is critically reviewed. This is particularly timely because of the change in the specification of the javelin for the men's event, which was introduced by the IAAF in 1986. A full discussion of the aerodynamics of the javelin is presented with due consideration of the change in pitching moment characteristics that the rules change had brought about. The uses and limitations of current computer programs for simulating javelin flight, in order to estimate optimal release parameters, are profiled. Consideration is also given to the effects of wind velocity, air density, javelin weight and the flutter and spin of the javelin on its flight.

The review further considers the optimization of release parameters, drawing upon computer simulations and field‐based data. The effects of release speed, release height, release angle, release angle of attack and release pitch rate are assessed. The javelin throwing technique is discussed in relation to cinematographically derived data, including an evaluation of experimental procedures. The importance to successful performance of the grip, the run‐up and transition phases, the cross over and delivery strides are each reviewed. Finally, some prognoses as to the direction of future research into this complex throwing skill are offered.  相似文献

This review is focused on anthropometric and physiological characteristics of soccer players with a view to establishing their roles within talent detection, identification and development programmes. Top-class soccer playershave to adapt to the physical demandsof the game, which are multifactorial. Players may not need to have an extraordinary capacity within any of the areas of physical performance but must possess a reasonably high level within all areas. This explains why there are marked individual differences in anthropometric and physiological characteristics among top players. Various measurements have been used to evaluate specific aspects of the physical performance of both youth and adult soccer players.The positional role of a player is related to his or her physiological capacity. Thus, midfield players and full-backs have the highest maximal oxygen intakes (> 60 ml·kg -1 ·min -1 ) and perform best in intermittent exercise tests. On the other hand, midfield players tend to have the lowest muscle strength. Although these distinctions are evident in adult and elite youth players, their existence must be interpreted circumspectly in talent identification and development programmes. A range of relevant anthropometric and physiological factors can be considered which are subject to strong genetic influences (e.g. stature and maximal oxygen intake) or are largely environmentally determined and susceptible to training effects. Consequently, fitness profiling can generate a useful database against which talented groups may be compared. No single method allows for a representative assessment of a player's physical capabilities for soccer. Weconclude that anthropometric and physiological criteria do have a role as part of a holistic monitoring of talented young players.  相似文献

Abstract

The keeper-independent strategy, in which a football penalty kicker selects a target location in advance and ignores the goalkeeper's actions during the run-up, has been suggested to be the preferable strategy for taking a penalty kick. The current in-field experiment investigated the question of whether the goalkeeper can indeed be ignored. Ten intermediate-level football players were instructed to adopt a goalkeeper-independent strategy and to perform penalty kicks directed at one of two targets located in the upper corners of the goal under three conditions: without a goalkeeper, in the presence of a goalkeeper (who tried to save the ball), and in the presence of a goalkeeper who was informed by the penalty kickers where they intended to direct the ball. The mere presence of a goalkeeper impaired shot accuracy. The shots were more centralised, that is, biased toward the goalkeeper. The effects were enhanced for the condition in which the penalty kicker knew the goalkeeper was knowledgeable about ball direction. The findings were consistent with the response activation model that holds that aiming at a target can be biased toward salient visual non-targets. The implications for adopting and practising goalkeeper-independent strategies are discussed.  相似文献
