College is an important time for young adults to establish healthy eating habits since students are at risk for gaining weight during the college years. An emerging area of research is examining the effect of meal-timing, which involves the timing of food intake throughout the day, in an effort to improve satiety and bodyweight. The purpose of this study was to examine the use of meal-timing among a sample of college students and to assess what aspects from an intervention could help them to adhere to meal-timing long term. Participants were randomly assigned to either a daytime group (≤30% total kcals after 5?pm) or a nighttime group (≥50% total kcals after 5?pm). After completing the intervention, almost half of participants (49%) reported they could adhere to meal-timing long-term. Having more resources that support meal-timing are needed to help students potentially achieve a healthy weight and prevent chronic diseases. 相似文献

This study evaluates the effect of the documentary Under the Dome on the concern and responsive behaviors of the public regarding air pollution in China, with two surveys conducted before and after watching the documentary. Employing difference-in-differences regression, this study answers two research questions: (1) Does Under the Dome change public concern about air pollution? (2) Does Under the Dome change public behaviors in response to air pollution, including protective behaviors (i.e., wearing face masks) and mitigation behaviors (i.e., reducing car driving)? We find that the information campaign (1) protects against the decline of public concern about air pollution in Beijing and (2) moderates the degree to which people's perceived severity, perceived susceptibility, and sense of self-efficacy influence protective behaviors and moderates the degree to which people's belief in the cooperative behaviors by others influences mitigation behaviors. This study provides evidence that information campaigns of the Under the Dome type are effective in raising public awareness; however, the information campaign did not directly influence public protective and mitigation behaviors. 相似文献

We consider the problem of scheduling a set of equal-length intervals arriving online, where each interval is associated with
a weight and the objective is to maximize the total weight of completed intervals. An optimal 4-competitive algorithm has
long been known in the deterministic case, but the randomized case remains open. We give the first randomized algorithm for
this problem, achieving a competitive ratio of 3.5822. We also prove a randomized lower bound of 4/3, which is an improvement
over the previous 5/4 result. Then we show that the techniques can be carried to the deterministic multiprocessor case, giving
a 3.5822-competitive 2-processor algorithm, and a 4/3 lower bound for any number of processors. We also give a lower bound
of 2 for the case of two processors.

This article combines the evaluation capacity building and nonprofit accountability literature to examine how nonprofits use evaluation data to address stakeholder expectations. Our study investigates how staff competency, technological resources, learning climate, and strategic planning influence a nonprofit's ability to demonstrate upward, lateral, and downward accountabilities. Results indicate different combinations of evaluation capacities matter more for particular stakeholder groups. We argue a more integrative nonprofit accountability requires that managers and staff know how to utilize evaluation results for internal and external audiences. Nuances between specific evaluative capacities and their influences on multiple accountabilities suggest several implications for practice. 相似文献

In what has become quite a turbulent quasi‐market for residential care for children and youth, providers now compete for public contracts. To create visibility and attract customers, many providers use marketing activities to project the desired impression of themselves to maintain or strengthen their market position. In this article, we analyse how companies that provide residential care for children manage the impressions they project on their websites and in advertisements. The results reveal that residential care providers use a range of impression management strategies to enhance their organizational image and to respond to potentially damaging or threatening images. The information providers choose to disclose leaves customers—in this case, the social workers responsible for choosing and purchasing care on behalf of clients—with rather limited opportunities to evaluate the quality of care. This is a significant problem considering other, more reliable, sources of information are difficult to access. 相似文献

AbstractThe profusion of data created by modern research has brought about increasing discussion on the practice of data management and the development of such infrastructure. Many universities and libraries are exploring how to address this issue using institutional repositories, the Hong Kong University of Science and Technology (HKUST) Library being one of them. As part of the exploration, the author conducted a case study of datasets at major institutional repositories. This paper visits the issues relating to data archiving, reports common practices of data treatment at institutional repositories, and presents a list of recommendations for experimenting data archiving at the HKUST Institutional Repository. 相似文献

A polynomial approximation scheme for minimizing makespan in a batch processing system under dynamic job arrivals is presented. A lower bound of
on the competitive ratio of any on-line algorithm is proved. This is matched by an on-line algorithm for the special case of unbounded machine capacity. 相似文献

This article highlights four qualitative studies that examine young diverse populations (i.e. middle-class African-American learners, Latinx immigrant children, emergent bilingual writers, and teachers of low-socioeconomic African-American learners) using culturally relevant and culturally sustaining pedagogies as our theoretical lens. The research questions are (1) What are the features of classrooms that support culturally sustaining learning for young children? (2) What social, cultural, and linguistic resources do learners draw upon when engaging in culturally sustaining spaces? Findings in this paper indicate that (a) children need critical safe spaces to foster CSP (b) children draw knowledge from varied resources and (c) teachers’ must be able to navigate policies to implement practices that utilize students’ cultural referents. 相似文献

This study used a marketing-research paradigm to explore gamblers’ attraction to EGMs based on different elements of the environment. A select set of environmental features was sourced from a prior study (Thorne et al. in J Gambl Issues 2016b), and a discrete choice experiment was conducted through an online survey. Using the same dataset first described by Rockloff et al. (EGM Environments that contribute to excess consumption and harm, 2015), a sample of 245 EGM gamblers were sourced from clubs in Victoria, Australia, and 7516 gamblers from an Australian national online survey-panel. Participants’ choices amongst sets of hypothetical gambling environments allowed for an estimation of the implied individual-level utilities for each feature (e.g., general sounds, location, etc.). K-means clustering on these utilities identified four unique market segments for EGM gambling, representing four different types of consumers. The segments were named according to their dominant features: Social, Value, High Roller and Internet. We found that the environments orientated towards the Social and Value segments were most conducive to attracting players with relatively few gambling problems, while the High Roller and Internet-focused environments had greater appeal for players with problems and vulnerabilities. This study has generated new insights into the kinds of gambling environments that are most consistent with safe play. 相似文献
