Developmental system theories recognize that variables from multiple levels of organization within the bioecology of human development contribute to adolescent development, including individual factors, family factors and the neighborhood which includes extracurricular activities. Extracurricular activities provide a context for youth development, and participation has been linked with positive developmental outcomes. This study uses data from a subsample of early adolescents in the 4-H Study of Positive Youth Development to determine whether neighborhood assets moderate the effect of adolescent activity involvement on positive and negative developmental outcomes. The relationship between activity involvement and neighborhood assets was different for girls as compared to boys when assessing outcomes of positive youth development, risk behavior, and depression. Consistent with a developmental systems perspective, the findings affirm the need for researchers and practitioners to consider multiple contextual influences when seeking to understand or promote, respectively, positive youth development.  相似文献

The world’s scientific community must be in a state of constant readiness to address the threat posed by newly emerging infectious diseases. Whether the disease in question is SARS in humans or BSE in animals, scientists must be able to put into action various disease containment measures when everything from the causative pathogen to route(s) of transmission is essentially uncertain. A robust epistemic framework, which will inform decision-making, is required under such conditions of uncertainty. I will argue that this framework should have reasoning at its center and, specifically, that forms of reasoning beyond deduction and induction should be countenanced by scientists who are confronted with emerging infectious diseases. In previous articles, I have presented a case for treating certain so-called traditional informal fallacies as rationally acceptable forms of argument that can facilitate scientific inquiry when little is known about an emerging disease. In this article, I want to extend that analysis by highlighting the unique features of these arguments that makes them specially adapted to cope with conditions of uncertainty. Of course, such a view of the informal fallacies must at least be consistent with the reasoning practices of scientists, and particularly those scientists (viz. epidemiologists) whose task it is to track and respond to newly emerging infectious diseases. To this end, I draw upon examples of scientific reasoning from the UK’s BSE crisis, a crisis that posed a significant threat to both human and animal health.

Statement of problemA variety of conceptions of qualitative research exist. This leads to a situation in which there are competing claims as to what counts as good-quality work. These competing claims revolve around the issue of criteria and how they are used to pass judgment on qualitative research. Those involved in sport and exercise sciences need to reflect on this issue with a view to generating further dialogue and a greater understanding of difference within the research community.MethodTwo ideal types of researcher, one a criteriologist the other a relativist, are constructed to illustrate how each might judge qualitative studies of different kinds.ResultsA comparison of the ways in which the criteriologist and the relativist draw on different assumptions to judge qualitative studies illustrates the constraining nature of the former and the expansive possibilities of the latter.ConclusionsCriteria should be viewed as lists of characterizing traits that are open to reinterpretation as times, conditions, and purposes change. Researchers need to adopt the role of connoisseur in order to pass judgment on different kinds of study in a fair and ethical manner.  相似文献

Aim: This case study of one woman's (Jane's) experience of dialogical journal writing presents a way of finding a ‘compassionate image’ for self‐therapy. Various theoretical analyses are indicated with Mindfulness‐based conceptualisations at the forefront. Methodology: Based on three recorded interviews, the narrative inquiry took place over a year. Methodologically, this paper is also one contribution to an ongoing debate about different research approaches in therapeutic writing research. Participants: This study took place in Aotearoa New Zealand, where both Jane and I are migrants. Discussion: This account draws on a report of self‐directed writing for well‐being, seen as an alternative to counselling or medication for depression and anxiety. It focuses on how a particular style of writing evolved and how the motivation to write continues.  相似文献

Changing informational constraints of practice, such as when using ball projection machines, has been shown to significantly affect movement coordination of skilled cricketers. To date, there has been no similar research on movement responses of developing batters, an important issue since ball projection machines are used heavily in cricket development programmes. Timing and coordination of young cricketers (n = 12, age = 15.6 ± 0.7 years) were analyzed during the forward defensive and forward drive strokes when facing a bowling machine and bowler (both with a delivery velocity of 28.14 ± 0.56 m s−1). Significant group performance differences were observed between the practice task constraints, with earlier initiation of the backswing, front foot movement, downswing, and front foot placement when facing the bowler compared to the bowling machine. Peak height of the backswing was higher when facing the bowler, along with a significantly larger step length. Altering the informational constraints of practice caused major changes to the information–movement couplings of developing cricketers. Data from this study were interpreted to emanate from differences in available specifying variables under the distinct practice task constraints. Considered with previous findings, results confirmed the need to ensure representative batting task constraints in practice, cautioning against an over-reliance on ball projection machines in cricket development programmes.  相似文献

A first-person shooter video game was adapted for the study of causal decision making within dynamic environments. The video game included groups of three potential targets. Participants chose which of the three targets in each group was producing distal explosions. The actual source of the explosion effect varied in the delay between the firing of its weapon and the effect (from 0 to 2 s), whether these programed average delays were constant or varied from shot to shot, and whether the delays were unfilled or filled with an auditory event. In Experiment 1, participants’ choice accuracy was highest with shorter delays, but there was no effect of filling the delay and some beneficial effect of varying the delay. These results were re-examined in Experiment 2 but with participants experiencing the same average delay for seven subsequent decisions before the next average delay was introduced. In this experiment, men showed a strong and consistent benefit of filling a delay whereas women did not. Participants’ behavior is considered within the context of a model that assumes that choice behavior is driven by experienced contiguity for the target and foils.  相似文献

In this commentary, the author first seeks to counterbalance the current focus on the cost of cultural value mismatch by calling attention to ample evidence in the literature that value mismatch can produce cultural adaptation and resilience in the long run, besides promoting cultural innovations and individual creativity. Second, we propose three factors that differentiate the benefits from the costs of cultural value mismatch. Personal orientation towards integrating heritage and host culture, accurate perception of cultural value differences, and supportive multicultural environments are associated with benefits. In contrast, dichotomous orientation towards one or the other culture, exaggeration of value differences between heritage and host culture, and assimilationist social environments are associated with costs. Third, our analysis of the decoupling between cultural values and ecological niches in the special issue led to observation of bidirectionality in cultural value mismatch: Whereas most articles in the Special Issue focus on the cross-cultural value mismatch that occurs when people move from a more rural, low-resource, less technological ecology into a more urban, high-resource, more technological ecology, we were able to document the effects of value mismatch when movement occurs in the opposite direction.  相似文献

We reexamined the psychometric properties of the Momentary Impulsivity Scale (MIS) in two young adult samples using daily diary (N = 77) and ecological momentary assessment (N = 147). A one-factor between- and within-person structure was supported, though “I felt impatient” loaded poorly within-person. MIS scores consistently related to emotion-driven trait impulsivity; however, MSSDs of MIS scores were unrelated to outcomes after accounting for aggregate MIS scores. We observed positive, within-person correlations with negative, but not positive, affect. Between-person MIS scores correlated with alcohol problems, though within-person MIS-alcohol relations were inconsistent. MIS scores were unrelated to laboratory-based impulsivity tasks. Findings inform the assessment of state-level impulsivity in young adults. Future research should prioritize expanding the MIS to capture the potential multidimensionality of state-level impulsivity.  相似文献

Previous studies have shown that people often use heuristics in making inferences and that subjective memory experiences, such as recognition or familiarity of objects, can be valid cues for inferences. So far, many researchers have used the binary choice task in which two objects are presented as alternatives (e.g., “Which city has the larger population, city A or city B?”). However, objects can be presented not only as alternatives but also in a question (e.g., “Which country is city X in, country A or country B?”). In such a situation, people can make inferences based on the relationship between the object in the question and each object given as an alternative. In the present study, we call this type of task a “relationships-comparison task.” We modeled the three inference strategies that people could apply to solve it (familiarity-matching [FM; a new heuristic we propose in this study], familiarity heuristic [FH], and knowledge-based inference [KI]) to examine people's inference processes. Through Studies 1, 2, and 3, we found that (a) people tended to rely on heuristics, and that FM (inferences based on similarity in familiarity between objects) well explained participants' inference patterns; (b) FM could work as an ecologically rational strategy for the relationships–comparison task since it could effectively reflect environmental structures, and that the use of FM could be highly replicable and robust; and (c) people could sometimes use a decision strategy like FM, even in their daily lives (consumer behaviors). The nature of the relationships–comparison task and human cognitive processes is discussed.  相似文献
