The E-Learning Outreach Program (ELOP) is a multisectoral, collaborative, and commitment-driven action research that focuses on providing relevant and useful computer and Internet literacy short courses for public elementary students. This study presents the critical action plans of setting up a pilot e-Learning station in Hen. Pio del Pilar Elementary School in Makati City and in Pulo Elementary School in Cabuyao City, Laguna, Philippines. The school’s computer laboratory was converted to an E-Learning station with additional devices and technical support from De La Salle University (DLSU). The study aims to account for a process-based heuristic approach in laying down the different phases of the program, specifically to: (1) coordinate and orient parents, pupils, teachers and school administrators, (2) set-up an e-Learning environment (3) design and write course modules (4) assess learning skills and experience of pupils, and (5) evaluate the program based on research team’s observation and results of the focus group discussion (FGD) with teachers and student-participants. In Pulo Elementary School, a pretest and posttests were conducted with results showing that the program has improved participants’ e-Learning knowledge and skills except for advance skills in hardware utilization. The participants also showed a strong positive attitude towards the ELOP.  相似文献

ABSTRACT

The aim of this study was to explore the effectiveness of Methadone Maintenance Treatment (MMT) from the perspective of drug users and their families. For this qualitative content analysis study, 15 participants were selected via purposive sampling. Data collection was done using deep and semi-structured interviews, which were then analyzed. The results showed that MMT can bring favorable impacts into the patients’ lives and help them with the process of treatment and rehabilitation despite the medical side effects.  相似文献

两周金文共有的第二人称代词有"女"、"乃"、"尔",它们的语法功能一直比较稳定。"余、朕、女、乃"和"我、尔"在殷商以前可能属于不同方言,后者之进入前者所在方言,可能就是为了补前者不表复数之不足。第二人称代词在殷商西周时可通用于各种身份的人之间,到东周春秋时期逐渐有了限制。从殷商西周到春秋战国,随着称谓礼仪的发展,称谓系统也发展得愈益丰富完善。  相似文献

Multisite evaluation has been cited as a strategy for building knowledge about a program's success and enhancing evaluation capacity and evaluation use. Even so, the extent to which data from these efforts are made available to individual project participants varies. This article describes a community-created multisite evaluation that was designed to overcome this limitation. Based on the negotiated centralized evaluation model and implemented within the context of a community of practice, the EvalFest community-created multisite evaluation has used shared measures to collect data from 30,000 participants from partner sites across the community over three years. This article describes the design characteristics of the community-created multisite approach, and presents results related to partners’ evaluation use that demonstrate the early success of this method. We conclude by considering how this strategy might be applied to other sectors.  相似文献

Objective: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. Participants: Participants were 526 young adults aged 18–23 (n?=?355 4-year students; n?=?171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Methods: Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. Results: Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Conclusions: Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students.  相似文献

Studies have mostly examined mental health service use of older Asian immigrant combining all Asian Americans into one group whereas immigration backgrounds and socioeconomic status of each Asian minority group are different. Therefore, this study aimed to identify predictors of mental health service use within specific ethnic groups among older Asian adults focusing on Chinese, Japanese, Korean, Filipino, and Vietnamese in California. The Behavioral Model for Vulnerable Populations (BMVP) is used to guide the secondary data analysis of a sample of 3,453 older Asian immigrants from the California Health Interview Survey (CHIS). Logistic and linear regression analyses are performed to examine predictors of mental health service use and the frequency of mental health service use, respectively. As results, mental health‐seeking patterns differ by ethnicity within the older Asian immigrant sample, not being married (Korean), higher levels of acculturation (Filipino), lower levels of neighborhood cohesion (Korean and Vietnamese), higher levels of perceived safety (Korean) and lower levels of perceived safety (Vietnamese), higher levels of mental distress (Korean and Filipino), and having perceived need (all) were related to more visits for mental health services. The study findings highlight the necessity of cultural competency services and programs for each Asian ethnicity.  相似文献

This study examined the characteristics of youth with different types of purpose in life, as well as the associations between adolescents’ life satisfaction, purpose in life, meaning in life, social support, and problematic digital use. The sample included 193 participants aged 14–18 who completed self-report questionnaires on life satisfaction, purpose in life, meaning in life, social support, and problematic digital use. The following purpose in life clusters were found: (1) other-oriented goals (n?=?33); (2) self-oriented goals (n?=?42); and (3) both other- and self-oriented goals (n?=?107). Adolescents with both self- and other-oriented goals had significantly higher life satisfaction, meaning in life, and social support compared to the other groups. Meaning in life and greater support from parents and teachers were significantly associated with greater life satisfaction. In addition, having other-oriented goals was associated with lower life satisfaction. Finally, support from parents (p?=?0.05) mediated the association between problematic digital use and life satisfaction. Findings are discussed in light of previous research and the theoretical and practical implications are examined.  相似文献

The sexual health problems experienced by homeless youth bring into question their use of available sexual health services. Using a qualitative typological analysis, this study aims to identify sexual health services utilization profiles for homeless youth, and to understand the role of the homeless experience on the utilization of sexual health services. Individual interviews were conducted with 33 homeless youth (17 men, 16 women) between 18 and 25?years of age. Typological analysis identified four profiles: (1) a targeted use of sexual health services to determine one’s serological status following a relational change during the homeless experience; (2) a limited use of sexual health services to manage sexual emergencies that arise during the homeless experience; (3) a regular use of sexual health services to avoid the risks associated with the homeless experience; (4) a frequent use of sexual health services to obtain support when engaging in prostitution during the homeless experience. This study shows that the precarious and unstable conditions within the homeless experience incite youth to utilize sexual health services in different ways. These findings point to the importance of rethinking sexual health services to better adapt them to the different utilization profiles of homeless youth.  相似文献
