OBJECTIVE: This study examined risk of placement disruption and negative placement outcomes (e.g., residential treatment and incarceration) among adolescents placed in traditional family foster care for a year or longer. A foster parent's report of externalizing behavior problems was expected to be a stronger predictor of disruption and negative outcomes than a caseworker's report. Additionally, the association between behavior problems and placement disruption was expected to be mediated by the youth's degree of belonging and integration in the foster home. METHOD: The caseworkers and foster parents of 179 randomly selected 12-13-year-old adolescents placed in traditional foster care were interviewed by telephone. Interviews included standardized measures of externalizing behavioral problems and several other variables that have been previously associated with placement movement. Disruption from the youth's foster home at the time of the interview was prospectively tracked for 5 years. RESULTS: Over half of the youth experienced a disruption of their placement. Contrary to expectations, behavior problems as reported by caseworkers, but not foster parents, were predictive of placement disruption. However, the foster parent's report of behavior problems predicted risk of negative outcome after a period of 5 years. As hypothesized, integration in the foster home was highly predictive of placement stability and mediated the association between behavior problems and risk of disruption. CONCLUSIONS: Results suggest that integration in the foster home might be an important dimension of placement adaptation that should be considered during service planning for foster youth in long-term foster care. In addition, using standardized measures of behavior with both foster parents and caseworkers might be necessary to assess both long-term risk of negative outcomes and more immediate risk of placement disruption. 相似文献

Areas of difficulty faced by our veterinary medicine students, with respect to their learning in dissection classes, were identified. These challenges were both general adult‐learning related and specific to the discipline of anatomy. Our aim was to design, implement, and evaluate a modified reciprocal peer‐assisted/team‐based learning format—Doing Dissections Differently (DDD)—to complement existing dissection classes, with the intention of enhancing both student learning and the student learning experience. Second year veterinary medicine students (n = 193), in their usual dissection groups, were randomly assigned to one of four roles: anatomist, clinician, radiologist, and learning resources manager. Students attended a preparatory workshop outlining the skills required for effective execution of their role. They were then asked to perform their roles throughout five consecutive musculoskeletal dissection classes. Student attitudes to dissection classes before and after DDD were evaluated by questionnaire (146 respondents). There was a significant (P = 0.0001) improvement after DDD in a number of areas: increased perceived value of dissection classes as an anatomy learning aid; improved appreciation of the clinical relevance of anatomy; increased use of resources before and during dissection classes; and longer preparation time for dissection classes. Before DDD, 45% of students felt that at least one peer did not contribute usefully to the group during dissection classes; no improvement was seen in this measure after DDD. Although the new format highlighted a potential need to improve teamwork, most students actively engaged with DDD, with dissection classes valued more highly and utilized more effectively. © 2012 American Association of Anatomists. 相似文献

The aims of this study were to describe the characteristics of older Australian university students (aged 60+ years); to identify the factors that motivate late-life, tertiary-level learning; and to capture older students’ views about the role of tertiary-level learning in promoting healthy aging. In 2012, an invitation to participate in the study was sent to all 39 Australian universities, seeking their support and cooperation to recruit students aged 60+ years into the study. Eligible participants were asked to complete an online survey that comprised a range of closed and open-ended questions related to their university study. Narrative data were coded into themes using an inductive approach in QSR NVivo. A total of 626 older students completed the online survey. Just over half (55%) of the sample were women, 86% were aged between 60–70 years of age, 49% held a graduate qualification, and the majority (69%) were born in Australia. Participants cited a range of personal and vocational motivations for enrolling in a university course. They believed that university-level learning kept the mind and brain active; enabled access to an interesting, challenging, and purposeful activity; promoted social engagement and intergenerational communication; and improved confidence, knowledge, and skills. Future prospective experimental studies of older learners are required to objectively assess the impact of university-level learning on their health and wellbeing, including cognitive function. These data will quantify the benefits of tertiary-level learning to older people and society. 相似文献

Individual growth trajectories of psychological phenomena are often theorized to be nonlinear. Additionally, individuals’ measurement schedules might be unique. In a structural equation framework, latent growth curve model (LGM) applications typically have either (a) modeled nonlinearity assuming some degree of balance in measurement schedules, or (b) accommodated truly individually varying time points, assuming linear growth. This article describes how to fit 4 popular nonlinear LGMs (polynomial, shape-factor, piecewise, and structured latent curve) with truly individually varying time points, via a definition variable approach. The extension is straightforward for certain nonlinear LGMs (e.g., polynomial and structured latent curve) but in the case of shape-factor LGMs requires a reexpression of the model, and in the case of piecewise LGMs requires introduction of a general framework for imparting piecewise structure, along with tools for its automation. All 4 nonlinear LGMs with individually varying time scores are demonstrated using an empirical example on infant weight, and software syntax is provided. The discussion highlights some advantages of modeling nonlinear growth within structural equation versus multilevel frameworks, when time scores individually vary. 相似文献

The purpose of the present study was to examine the effectiveness of two learning strategies, self-explanation and elaborative interrogation, for the retention of scientific facts. University students (N= 55) were asked to learn facts about the cardiovascular system using one of three approaches. Self-explanation participants were required to explain what the facts meant to them and how they related to their prior knowledge. Elaborative interrogation participants answered “why” the facts made sense. Finally, the control group simply repeated the facts aloud. Self-explanation participants significantly outperformed elaborative interrogation and repetition control participants on measures of cued recall and recognition. Elaborative interrogation was no more effective than repetition. Results were discussed in terms of the practicality and flexibility of each approach. 相似文献

This nationwide survey studies the impact of convergence on reporters and producers in small and medium local television markets. The article examines the manner in which convergence-related responsibilities affect the daily routines of these news workers. It also assesses their perceptions of convergence and challenges they face, including concerns about the impact of convergence on the quality of their work. Authors compare these views to the opinions of news directors across the United States (gathered in previous research), finding significant differences between news workers' perspectives and those of their bosses. 相似文献

When missingness is suspected to be not at random (MNAR) in longitudinal studies, researchers sometimes compare the fit of a target model that assumes missingness at random (here termed a MAR model) and a model that accommodates a hypothesized MNAR missingness mechanism (here termed a MNAR model). It is well known that such comparisons are only interpretable conditional on the validity of the chosen MNAR model’s assumptions about the missingness mechanism. For that reason, researchers often perform a sensitivity analysis comparing the MAR model to not one, but several, plausible alternative MNAR models. In the social sciences, it is not widely known that such model comparisons can be particularly sensitive to case influence, such that conclusions drawn could depend on a single case. This article describes two convenient diagnostics suited for detecting case influence on MAR–MNAR model comparisons. Both diagnostics require much less computational burden than global influence diagnostics that have been used in other disciplines for MNAR sensitivity analyses. We illustrate the interpretation and implementation of these diagnostics with simulated and empirical latent growth modeling examples. It is hoped that this article increases awareness of the potential for case influence on MAR–MNAR model comparisons and how it could be detected in longitudinal social science applications. 相似文献

In the anatomical sciences, e‐learning tools have become a critical component of teaching anatomy when physical space and cadaveric resources are limited. However, studies that use empirical evidence to compare their efficacy to visual‐kinesthetic learning modalities are scarce. The study examined how a visual‐kinesthetic experience, involving a physical skeleton, impacts learning when compared with virtual manipulation of a simple two‐dimensional (2D) e‐learning tool, A.D.A.M. Interactive Anatomy. Students from The University of Western Ontario, Canada (n = 77) participated in a dual‐task study to: (1) investigate if a dual‐task paradigm is an effective tool for measuring cognitive load across these different learning modalities; and (2) to assess the impact of knowledge recall and spatial ability when using them. Students were assessed using knowledge scores, Stroop task reaction times, and mental rotation test scores. Results demonstrated that the dual‐task paradigm was not an effective tool for measuring cognitive load across different learning modalities with respect to kinesthetic learning. However, our study highlighted that handing physical specimens yielded major, positive impacts on performance that a simple commercial e‐learning tool failed to deliver (P < 0.001). Furthermore, students with low spatial ability were significantly disadvantaged when they studied the bony joint and were tested on contralateral images (P = 0.046, R = 0.326). This suggests that, despite limbs being mirror images, students should be taught the anatomy of, as well as procedures on, both sides of the human body, enhancing the ability of all students, regardless of spatial ability, to take anatomical knowledge into the clinic and perform successfully.

Scholars maintain that when race and racism are addressed as factors that continue to shape inequality in the classroom, white students often deny the validity of these claims, while Students of Color tend to feel empowered by them. However, drawing on open-ended interviews, focus group discussions, and survey data, we argue that some Students of Color resist critical race pedagogy and curriculum. Specifically, we identify and analyze how this push back is articulated through three triggers: (1) an entrenchment in majoritarian ideologies; (2) a disavowal of racialized oppression; and (3) a disinclination to scrutinize personal experiences marred by race. These dynamics illustrate what we call ‘resisting decolonization’ – a reluctance to grapple with pedagogies that destabilize dominant ideologies about race and racism in schools and disrupt mainstream ideas regarding ethnic or racial identity. We introduce this concept in an attempt to hone critical race pedagogy to better address the needs of Students of Color who sometimes unknowingly participate in the marginalization of Populations of Color through deficit thinking or through the denial of the continuing significance of race. 相似文献
