Action research provides an opportunity to implement and understand the process of change in practice settings, as well as develop theoretical insights into complex social situations. The provision of mental healthcare for older people within the general hospital is one such situation, and this paper presents a discussion and reflection on the use of action research in this setting. The background to the project is described, followed by a discussion of three major issues that emerged for us: the extent to which we were able to promote democracy and maintain and demonstrate democratic behaviour, the problems and pitfalls of operationalising grounded theory methodology within an action research approach, and the challenges of developing an authentic and credible account of the care of older people with mental health needs. This paper aims to add to a discourse regarding action research and will be of value to researchers using this approach across a range of health, social care and educational settings.  相似文献

In many testing programs it is assumed that the context or position in which an item is administered does not have a differential effect on examinee responses to the item. Violations of this assumption may bias item response theory estimates of item and person parameters. This study examines the potentially biasing effects of item position. A hierarchical generalized linear model is formulated for estimating item‐position effects. The model is demonstrated using data from a pilot administration of the GRE wherein the same items appeared in different positions across the test form. Methods for detecting and assessing position effects are discussed, as are applications of the model in the contexts of test development and item analysis.  相似文献

Although teaching is frequently cited as a stressful profession, limited recent Norwegian data is available. This study addressed the extent to which organizational climate and individual and organizational well-being outcomes vary between schools in rural, urban, and city locations. Participants were predominantly female (68%), aged 45+ years (63.2%) and reported 20+ years of teaching experience (51%). Teachers from rural schools reported smaller student and teacher numbers, a more positive organizational climate and better organizational well-being. Multi-level analyses, with teachers grouped within school location, indicated that personality is most strongly associated with employee well-being, and organizational climate most strongly related to school morale and distress. Schools in rural locations are smaller and possess workplace climates that are conducive to positivity in the workplace, and subsequently better workplace well-being outcomes.  相似文献

Over the last decade, community leaders have connected with students through school‐based mentoring (SBM) programs (e.g., adults who mentor at‐risk students). However, research in the area of SBM is only on the cusp of understanding relationship elements for impacting youth. In this collective case study, we examined the perceptions and experiences of 11 selected mentors in dyadic relationships (i.e., mentee and mentor) to understand better ways to retain and to engage mentors for longer‐lasting mentoring relationships, providing a sense of connectedness for students. Specifically, we investigated purposes and approaches of mentoring through the voices and experiences of mentors working with elementary‐aged students in SBM. Results revealed self‐sustaining synergy within the dyads (with little or no program support) and themes of consistency, commitment, spirituality, playfulness, the use of self‐disclosure, creativity, and emphasis on the present. In addition, implications for cross‐cultural and, in particular, cross‐age mentoring are discussed. One exemplar case illustrates specific profile characteristics used to bridge age, gender, and cultural differences.  相似文献

This article details the work of the Birmingham Initiative, a Methodist inspired, ecumenical research project that operated in Birmingham, in the West Midlands of the United Kingdom between 1995 and 1999. As the Christian Education Development Officer employed by this project, the author undertook doctoral research among twenty-six inner-city, Black majority churches from Methodist, Baptist Anglican, and Reformed Church traditions. One of the central aims of the research was to create the first African-centered Black Christian Education of Liberation for the British context. The major outcome of this research was the creation of the first practical Black Christian education curriculum in Britain, entitled Growing into Hope.  相似文献

In nineteenth- and early twentieth-century Europe, the age of the governess coincided with the age of nationalism. This paper explores the connection between them in the specific context of intercultural education by foreign governesses. It argues that nationalism, with its focus on the identification and projection of a distinct national character, led to the stereotyping of European countries and, by extension, the stereotyping of foreign governesses. It further contends that the clichéd images of the English Miss, German Fräulein and French Mademoiselle, which were international, powerful and largely negative, had, on the whole, a detrimental effect on governesses and their working relationships with employers and pupils. It concludes that stereotyping along national lines adversely affected both visitor and host by promoting formulaic and prejudicial attitudes one to the other.  相似文献

An anthropometric analysis was conducted on 35 elite male Australian track cyclists having a mean age of 22.6 years and who had been competing on average for 9 years. The relationship of anthropometric parameters to both bicycle saddle height and cycling performance was also investigated. Subjects were allocated, for purposes of comparison, to an endurance or sprint group on the basis of their competitive event. The group members in total were ectomorphic mesomorphs of height 178±4.8 cm and weight 72.5 ±6.6 kg on average. Percentage of saddle height to lower limb length averaged 99±1.6%, and significant correlations existed between strength and both body mass (r=0.57) and thigh girth (r = 0.55). No significant correlation was seen between any anthropometric parameter and performance in an individual event. Cyclists in the sprint group were heavier (76.2 ± 7.4 vs. 70.0 ± 4.7 kg, P<0.01) and stronger (258 ± 44.4 vs. 216 ± 30.5 Nm, P<0.01), and had larger chest (98.2 ± 6.2 vs. 92.4 ± 2.9 cm, P<0.01), arm (33.0±2.2 vs. 30.7± 1.6 cm, P<0.01), thigh (57.5 ± 3.4 vs. 54.3 ± 2.5 cm, P<0.01) and calf girths (37.8±1.7 vs. 36.2±1.9 cm, P<0.05) than cyclists in the endurance group. They were also more mesomorphic (5.3 ± 0.7 vs. 4.7 ± 0.8, P<0.05) and less ectomorphic (2.3 ± 0.9 vs. 2.9±0.6, P<0.05) than the endurance cyclists.  相似文献

Our understanding of the relationship between physical activity and health is constantly evolving. Therefore, the British Association of Sport and Exercise Sciences convened a panel of experts to review the literature and produce guidelines that health professionals might use. In the ABC of Physical Activity for Health, A is for All healthy adults, B is for Beginners, and C is for Conditioned individuals. All healthy adults aged 18–65 years should aim to take part in at least 150 min of moderate-intensity aerobic activity each week, or at least 75 min of vigorous-intensity aerobic activity per week, or equivalent combinations of moderate- and vigorous-intensity activities. Moderate-intensity activities are those in which heart rate and breathing are raised, but it is possible to speak comfortably. Vigorous-intensity activities are those in which heart rate is higher, breathing is heavier, and conversation is harder. Aerobic activities should be undertaken in bouts of at least 10 min and, ideally, should be performed on five or more days a week. All healthy adults should also perform muscle-strengthening activities on two or more days a week. Weight training, circuit classes, yoga, and other muscle-strengthening activities offer additional health benefits and may help older adults to maintain physical independence. Beginners should work steadily towards meeting the physical activity levels recommended for all healthy adults. Even small increases in activity will bring some health benefits in the early stages and it is important to set achievable goals that provide success, build confidence, and increase motivation. For example, a beginner might be asked to walk an extra 10 min every other day for several weeks to slowly reach the recommended levels of activity for all healthy adults. It is also critical that beginners find activities they enjoy and gain support in becoming more active from family and friends. Conditioned individuals who have met the physical activity levels recommended for all healthy adults for at least 6 months may obtain additional health benefits by engaging in 300 min or more of moderate-intensity aerobic activity per week, or 150 min or more of vigorous-intensity aerobic activity each week, or equivalent combinations of moderate- and vigorous-intensity aerobic activities. Adults who find it difficult to maintain a normal weight and adults with increased risk of cardiovascular disease or type 2 diabetes may in particular benefit from going beyond the levels of activity recommended for all healthy adults and gradually progressing towards meeting the recommendations for conditioned individuals. Physical activity is beneficial to health with or without weight loss, but adults who find it difficult to maintain a normal weight should probably be encouraged to reduce energy intake and minimize time spent in sedentary behaviours to prevent further weight gain. Children and young people aged 5–16 years should accumulate at least 60 min of moderate-to-vigorous-intensity aerobic activity per day, including vigorous-intensity aerobic activities that improve bone density and muscle strength.  相似文献

Abstract

In the sport of cricket the objective of the “no-ball” law is to allow no performance advantage through elbow extension during ball delivery. However, recently it has been shown that even bowlers with actions that are considered within the law show some elbow extension. The objective of this study was to investigate: [1] the effect of elbow orientation during anatomical landmark digitisation and [2] the choice of upper arm tracking cluster on the measurement of elbow angles during cricket bowling.

We compared the mean elbow angles for four different elbow postures; with the joint flexed at approximately 130°, 90°, in full extension and with the elbow flexed with the humerus internally rotated, and two upper arm clusters in two different situations: [1] during a controlled movement of pure flexion-extension and [2] during cricket bowling. The digitised postures of the anatomical landmarks where the elbow was extended and at 90° of flexion were more repeatable than the other two postures. The recommendation of this study when analysing cricket bowling is to digitise the humeral epicondyles with the joint flexed at 90°, or in full extension, and to relate their positions to an upper arm cluster fixed close to the elbow.  相似文献
