Approximately one in five people in developed countries such as Canada and Australia will experience mental illness during their lifespan, and this statistic may be even higher for people between the ages of 18 and 25. Due to widespread stigma and other issues, access to mental health care is limited. However, given the heavy online use by people in this age range as well as the prevalence of existing online health information, it is possible that “e-mental health,” when delivered in an efficacious and engaging format, could be a viable dissemination option. A quantitative and qualitative online survey was distributed to university students in order to determine their opinions of currently available e-mental health resources. Within the sample (n = 1308), text-based searching on Web sites such as Google as well as reading informational Web sites were the most highly preferred and utilized methods. However, a significant knowledge gap regarding the existence of other e-mental health formats was noted. Suggestions for future research include search engine optimization changes and continued development of e-mental health resources.  相似文献

Zusammenfassung. Um einen auf UML basierenden Entwicklungsprozess bewerten und verbessern zu können, werden Metriken für UML-Modelle definiert. Wir stellen einen Satz derartiger Metriken vor und diskutieren ihre Tauglichkeit. Unsere Metriken sind generisch definiert, sie werden zur Bewertung der einzelnen UML-Diagramme spezialisiert. Wir berichten vom Einsatz der Metriken zur Evaluation eines Prozessmodells, das in der Lehrveranstaltung Software-Praktikum eingesetzt wird. Eingegangen am 2. Januar 2001/Angenommen am 20. Dezember 2002CR Subject Classification: D.2.2, D.2.8, D.2.9, K.3.2, K.6.3  相似文献

This article discusses the theory I have come to rely on most consistently to collect and analyze data, interpret interactions at exhibits, and understand power dynamics within museums at many levels of analysis. Activity Theory has, for me, demonstrated the greatest versatility in informing, supporting, and reciprocally intertwining practice and theory. I describe my own evolutionary process here in the context of Activity Theory in order to demonstrate how I have come to see the theory reflected in my research design and analysis.  相似文献

Both picture exchange, a low-tech picturebased communication system, and technologybased interventions, such as the iPad? with communication application, are emerging treatments for students with autism spectrum disorder (ASD), according to the National Autism Center (2009). Recently, investigations regarding the use of the Apple iPad? to communicate have been conducted with mixed results. The authors used a single-subject alternating treatment design during an extended school year (ESY) program for students with disabilities to compare the independent use and effectiveness of the two approaches (low-tech picture-based versus iPad? equivalent) for three pre-school and two elementary students with ASD and developmental delay (DD). The authors concluded that teaching low-tech picture exchange prior to introducing the iPad? may be effective progression in teaching communication reciprocity skills for some students with ASD/DD. Limitations and strengths of both technologies are discussed.  相似文献

The cognitive processes used by children during problem solving have received considerable attention in recent years. The identification of the processes used by both successful and unsuccessful problem solvers has been hampered by the difficulties involved in making accurate observations of mental processes which may or may not have physical manifestations during problem solving. In addition, problem solvers themselves often are unaware of many of the thought processes they use while attempting to solve problems. The most popularly used methods for studying problem solving processes are not sufficiently reliable or valid. This study explored the potential effectiveness of a new procedure for identifying and studying certain of the cognitive processes used during problem solving. In addition, the procedure was used to categorize the types of conceptual thinking problem solvers employ, to study the use of trial and error behavior, and to investigate problem solvers’ abilities to coordinate multiple bits of information. It appears that the procedure has application for generating hypotheses about cognitive processes problem solvers use.  相似文献

We review published single subject design (SSD) studies that examine the effects of interventions for English learners at‐risk or with learning disabilities. Results of our literature search yielded 10 studies, five in reading, one in reading and behavior, and four in mathematics that met our inclusion criteria. Seven studies targeted Spanish‐speaking English learners, and three studies included students who spoke other languages than English and/or English only students. Two studies in mathematics included native language instruction. Six studies included English learners in second grade and above, and one study included high school students. We were able to calculate effect sizes (Hedges g) for eight of the 10 studies. Findings indicated a significant effect of the intervention for 12 of the 18 dependent variables measured. SSD methodology has the potential to help researchers and practitioners better understand what interventions work for English learners, and under what circumstances.  相似文献

ABSTRACT:  Commercial, nonthermal processing of food, such as high hydrostatic-pressure processing (HPP), has increased. The safety and quality of foods produced by HPP has not been well communicated to the public. An online, nationwide consumer survey was implemented to assess awareness of alternative food processing technologies, consumer food safety attitudes and knowledge, and willingness to pay (WTP) for HPP products. The consumer survey was administered by Zoomerang™, an online survey clearinghouse. The survey was completed by 1204 adults. Frequencies and crosstabs were calculated on Zoomerang and SPSS used for one-way ANOVA and chi-square analyses. The survey assessed knowledge of HPP, attitudes about new food processing techniques, WTP for HPP foods and demographics. Overall, many demographic characteristics reflected U.S. census population. While traditional methods, that is, canning, freezing, and microwaving were all well recognized by over 80% of respondents, only 8% recognized HPP. Trends indicated an increase in age, education, and income reflected greater food safety knowledge. Regardless of demographics, no survey respondent exhibited knowledge mastery (80%). Given an explanation of HPP and its benefits, 39% of respondents indicated they would be WTP an additional cost, with higher income and education having the most impact. Majority of respondents indicated a WTP of $0.25 to $0.50 regardless of the value of the food product. More respondents were WTP slightly more for a more expensive product. New technologies often encounter a stumbling block in consumer acceptance and processing costs. A consumer's WTP, once they were informed, could encourage industry to look favorably on this technology.  相似文献

The purpose of this study conducted in 36 infant–toddler centres (Kinderkrippen) in the city of Munich in Bavaria/Germany was to explore structural characteristics of early child care and education and their effects on child care quality. Stepwise regressions and variance analysis (Manova) examined the relation between quality of care and structural characteristics such as group size, staff competence and preparation time. A multi‐respondent approach was employed, including self‐report questionnaires of educators (Erzieherinnen) as well as data on local working conditions collected from the directors of the centres. The findings of this study suggest that different sets of variables can be used to predict quality of education for under‐threes. The practitioners' reported quality of education was found to relate to higher competence (with regard to centre programme, documentation, teamwork and staff qualification), better orientation towards the children's needs and better working atmosphere. Furthermore there were multivariate effects of the availability of and networking with external specialists, preparation time, and grouping arrangements within the centre such as changing from a home‐group approach to an open‐group setting. The findings are discussed in terms of their implications for research and the basic impact of education in early childhood.  相似文献
