Although the HIV/AIDS epidemic began more than twenty years ago, there still is no cure for the disease and no vaccine to prevent infection. As with the general population, individuals with HIV/AIDS have sought care using a variety of traditional and nontraditional approaches. The popularity of complementary and alternative interventions among the HIV/AIDS community continues. To understand better the distribution of the HIV/AIDS body of knowledge concerning complementary and alternative medicine (CAM), this study sought to (1) examine the literature specific to the use of complementary and alternative medicine where HIV/AIDS is concerned to determine publication patterns; (2) determine the degree of overlap among bibliographic citation databases that index the literature concerning the use of CAM practices in treating HIV/AIDS; and (3) facilitate access to this body of literature.  相似文献

This is a qualitative study of how the Advancement Via Individual Determination (AVID) program influenced 9 African American young men in southeastern North Carolina. To understand the impact of the program, a cross-section of current and past AVID participants were interviewed. The African American male students were asked about their attitudes toward education and how AVID influenced them socially and academically. Four themes that emerged from the data were: (a) Supportive, family-like relationships are built within the AVID classroom; (b) the students strive to do better academically; (c) specific AVID methodologies improve student achievement in preparation for college; and (d) AVID positively affects student attitudes toward education. These themes are discussed in relation to the literature. Finally, we suggest how this research might inform future studies.  相似文献

Past research has shown that when given a simultaneous visual-discrimination midsession reversal task, pigeons typically anticipate the reversal well before it occurs and perseverate after it occurs. It appears that they use the estimation of time (or trial number) into the session, rather than (or in addition to) the more reliable cue, the outcome from the previous trial (i.e., a win–stay/lose–shift response rule), to determine which stimulus they should choose. In the present research, we investigated several variables that we thought might encourage pigeons to use a more efficient response strategy. In Experiment 1, we used a treadle-stepping response, rather than key pecking, to test the hypothesis that reflexive key pecking may have biased pigeons to estimate the time (or trial number) into the session at which the reversal would occur. In Experiment 2, we attempted to make the point of reversal in the session more salient by inserting irrelevant trials with stimuli different from the original discriminative stimuli, and for a separate group, we added a 5-s time-out penalty following incorrect choices. The use of a treadle-stepping response did not improve reversal performance, and although we found some improvement in reversal performance when the reversal was signaled and when errors resulted in a time-out, we found little evidence for performance that approached the win–stay/lose–shift accuracy shown by rats.  相似文献

Librarians are committed to supporting teaching, learning, and research. They are equally committed to supporting student success and retention. Demonstrating the impact that learning management system (LMS) embedded librarians make on student learning has been difficult to correlate, however. Studies that assess this connection, using qualitative and quantitative data have been undertaken in recent years. In a university regional campus library study conducted in 2016–2017, LMS embedded librarians explored the relationship between student learning and information literacy instruction, relying primarily on a customized LMS embedded librarian page of library resources and learning objects. They used a rubric to assess student research papers and bibliographies, LMS course analytics, instructors’ grades, and student feedback. This article reviews the literature and their methodology, challenges, and findings. They wish to guide colleagues, committed to assessing how librarians contribute to student learning, in selecting assessment approaches and validate their instructional role.  相似文献

Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators. Participants included 4085 Finnish youth (43.9% boys; Mage = 14.56, SD = .75; 97% born in Finland). Concurrently, defending was positively associated with self-reported victimization in classrooms with high bullying-popularity norms (b = .28, SE = .16). Defending was negatively associated with peer-reported victimization in classrooms with high defending-popularity norms (b = −.07, SE = .03). Defending was not significantly associated with future victimization, suggesting that it is generally not a risk factor for victimization.  相似文献

Learning environments can support the development of foundational knowledge and promote children's attitudes toward learning and school. This study explores the relation between school enjoyment and general knowledge from preschool (2016–2017) to kindergarten (2017–2018) in 1359 children (Mage = 55, 61 months, female = 50%; 58.5% Hispanic, 17% Black, 10% Asian, 10% White, 5% multiracial/other; linguistically diverse). Cross-lagged panel models showed significant bidirectional associations between preschool enjoyment and change in general knowledge from preschool to kindergarten with a standardized coefficient of β = .21 (p < .001) and associations between preschool general knowledge and change in enjoyment, β = .09 (p = .015). Exploratory analyses with teacher characteristics and demographic subgroup comparisons are discussed. These associations suggest the potential intervention strategy of promoting early school enjoyment to support broader academic development.  相似文献

In this study, we sought to identify how feedback about classroom observations affected novice university mathematics instructors’ (UMIs) teaching practices. Specifically, we examined how a Red–Yellow–Green feedback system (RYG feedback) affected graduate student instructor (GSI) scores on an observation protocol (GSIOP). The protocol was developed specifically for this population, and both the GSIOP and RYG feedback were used within a peer mentoring program for GSIs, wherein novice GSIs were mentored by more experienced GSIs. Mentors observed novices’ classrooms using the GSIOP and provided RYG feedback as part of observation–feedback cycles. We analyzed 100 sets of scores, each collected over the course of a semester containing on average three observation–feedback cycles. Analyzing the semester-long datasets longitudinally provided insight into what types of feedback informed and influenced observed teaching. After qualitatively coding the feedback provided to the GSIs by their mentors along multiple dimensions, we found certain forms of feedback were more influential for observable changes in GSIs’ teaching. For example, pedagogical feedback that included contextualization (context and focal events) demonstrated a more positive change in GSIOP score than feedback that lacked contextualization. Our results suggest that contextual formative feedback has a positive change to student-focused and teacher-focused observations.
