ABSTRACTThe aim of this article is to determine the perceptions and experiences of climbing at artificial climbing walls (ACWs) as undertaken by a cohort of ‘young-old’ people (approximately 65–75 years). The engagement of older people in outdoor activities and adventure is an evolving topic; however, as part of this development, little has been written on the use of ACWs. Methodologically, the research employed in-depth semi-structured focus groups and interviews with a purposive convenience sample of six recreational climbers, subsequently expanded to ten through snowball technique. Both sexes were equally represented. Manual thematic analysis identified two key motifs: ACWs and the notion of adventure, and ACWs and the potential for learning. The findings point at what constitutes ‘real’ adventure for this group of older adults; the shifting nature of ‘old age’; the significance of self-awareness; and the role of reflexivity and physical activity in the construction of a ‘successful’ old age. 相似文献

OBJECTIVE: The purpose of this study was to present the epidemiology of homicide among children younger than 6 years of age in Jefferson County, Alabama. This study focused on obtaining great detail on homicides and suspicious deaths occurring within a fixed population. METHODS: For purposes of this study, cases included Jefferson County deaths attributed to "homicide" or that were "undetermined" as noted in the coroner files among children younger than 6 years of age who were born and died between January 1, 1988 and December, 31, 1998. Victim and offender characteristics were obtained from the Jefferson County Coroner/Medical Examiner Office records. Environmental factors and circumstances surrounding the death were noted as well. RESULTS: The 53 study subjects were mainly female (55%), Black (69%), younger than 2 years of age (85%), had single mothers (38%), and a history of abuse (53%). Offenders were more likely to be male (64%), Black (73%), and a parent of the victim (53%). Homicides primarily resulted from an angry impulse (61%), with hands the most common weapon (61%). CONCLUSIONS: The majority of deaths in this study occurred among children younger than age 2, with a high proportion of fatalities among Black children of unmarried mothers. The offender most often knew the victim, with half of all homicides and two-thirds of all infant homicides involving a parent. More than half of the homicides resulted from an angry impulse, while the most common scenario for deaths with undetermined intent involved the caretaker finding the child unresponsive. 相似文献

Classroom quality is critical for young children's learning, yet evidence suggests that the quality of early care and education (ECE) classrooms varies widely, even within federally administered Head Start. This study uses data from the nationally representative Head Start Impact Study to examine variation in children's access to formal and high-quality ECE by policy characteristics that demonstrate a state's commitment and approach to regulating ECE quality. Findings support existing evidence of the impact of randomization to Head Start on children's access to formal and high-quality ECE, and expand our understanding of the ways in which these impacts vary. Overall, we find that stronger state child care licensing regulations and other indicators of a child-friendly policy climate are associated with a smaller contrast between the Head Start versus control groups' access to both formal and high-quality ECE. This study also offers initial evidence that state regulations targeting the quality of an ECE program's professional environment may be particularly important for access to high-quality classrooms. 相似文献

Three experiments explored responses to molar and local schedule constraints. Thirsty rats pressed a lever for access to a water spout. In Experiment 1, response totals were unaffected by two local schedule characteristics—the variability of the instrumental requirement and the variability of the magnitude of contingent reward. Experiment 2 manipulated the correlation between the instrumental requirement and the magnitude of reward. This correlation did not affect the behavioral price ratio (presses per lick) at a molar level. At a local level, the positive correlation created a lower mean lick price than did the negative correlation. The rats licked more, and licked less efficiently, under the positive correlation than under the negative correlation. Experiment 3 compared two ways of manipulating the molar presses/lick ratio: The instrumental (contingent) series varied the instrumental (contingent) requirement, but held the other requirement constant. As the ratio increased, total leverpresses increased, and total licks decreased linearly; the two series did not differ significantly. At higher lick prices, the rats licked more efficiently and made more extra licks at the spout as it closed. The results help delimit the applicability of molar models of the organism’s response to schedule constraints. 相似文献

Web-based learning: Challenges in using the Internet in the undergraduate curriculum. 总被引:1,自引:0,他引:1
Often compared to Gutenberg's introduction of the printing press in the 1450s, the use of the Internet in education, and especially within the undergraduate curriculum is ubiquitous. Yet the development and presentation of electronic undergraduate curriculum specifically on the Internet is a relatively new venture. Although guidelines for course development are emerging as quickly as the technology is introduced, several problems associated with i) style (appropriateness and effectiveness), ii) process (mechanistic and communication based), and iii) edited content of relevant information, continue to exist in the typical undergraduate applications. This paper describes the development of electronic curriculum in two undergraduate courses. The courses were an Introduction to Quantitative Methods, and an Introduction to Epidemiology; both of which typically use computers and as such, the introduction of advanced technology was not expected to have been an issue. In addition to the successes and shortcomings experienced in the presentation of these courses, the paper discusses an underlying theoretical framework upon which the development of the Internet components of the courses were based. 相似文献

The traditional approach to universal primary education (UPE) in developing countries has emphasised supply factors of schooling systems, such as the construction of schools and teacher training facilities, revisions to curricula and improvements in teaching materials. No doubt all these factors have played an important part in encouraging the growth of enrolment ratios throughout the developing world during the past two decades. But the profile of absentees from school, and the disproportionate enrolment of boys and girls in school suggest that this approach is unlikely to achieve full UPE. This paper calls for consideration of demand factors which may prevent children from attending school. Focusing on the household as the relevant unit, it examines the costs incurred when a child attends school in the developing world, and the benefits to be gained from school attendance. The paper then goes on to consider the case of Botswana, where, within the context of the goal of UPE, the government is investing vast resources in the expansion and improvement of the primary school system. Yet substantial numbers of children, boys in particular, continue to be withheld from school. After an analysis of the demand factors which prevent children from attending school in rural Botswana, the paper concludes with a discussion of the additional policies the Botswana government might find necessary to employ in order to achieve full UPE. 相似文献

The Two Cultures of Undergraduate Academic Engagement 总被引:2,自引:0,他引:2
Steven Brint Allison M. Cantwell Robert A. Hanneman 《Research in higher education》2008,49(5):383-402
Using data on upper-division students in the University of California system, we show that two distinct cultures of engagement
exist on campus. The culture of engagement in the arts, humanities and social sciences focuses on interaction, participation,
and interest in ideas. The culture of engagement in the natural sciences and engineering focuses on improvement of quantitative
skills through collaborative study with an eye to rewards in the labor market. The two cultures of engagement are strongly
associated with post-graduate degree plans. The findings raise questions about normative conceptions of good educational practices
in so far as they are considered to be equally relevant to students in all higher education institutions and all major fields
of study.

The aim of this exploratory study was to learn about the misconceptions that may arise for elementary and high school science teachers in their reflections on science and engineering practice. Using readings and videos of real science and engineering work, teachers’ reflections were used to uncover the underpinnings of their understandings. This knowledge ultimately provides information about supporting professional development (PD) for science teachers’ knowledge of engineering. Six science teachers (two elementary and four high school teachers) participated in the study as part of an online PD experience. Cunningham and Carlsen’s (Journal of Science Teacher Education 25:197–210, 2014) relative emphases of science and engineering practices were used to frame the design of PD activities and the analyses of teachers’ views. Analyses suggest misconceptions within the eight practices of science and engineering from the US Next Generation Science Standards in four areas. These are that: (1) the nature of the practices in both science and engineering research is determined by the long-term implications of the research regardless of the nature of the immediate work, (2) engineering and science are hierarchical, (3) creativity is inappropriate, and (4) research outcomes cannot be processes. We discuss the nature of these understandings among participants and the implications for engineering education PD for science teachers. 相似文献
