Volunteer motivation,social problem solving,self-efficacy,and mental health: a structural equation model approach

The study aimed to investigate the direct effect of volunteer motivation on social problem-solving ability, self-efficacy, and mental health and examine the mediating effects on volunteer motivation and mental health by testing social problem-solving ability and self-efficacy. We examined a hypothetical model that integrates the concepts of Self-Determination Theory, the Social Problem Solving Model, and the Self-Efficacy Belief Model. Results demonstrated that volunteer motivation was significantly associated with social problem-solving ability and self-efficacy amongst 1530 undergraduate students. Three subscales of social problem-solving ability (positive problem orientation, negative problem orientation, and avoidance style) and self-efficacy served are significant mediators. Model statistics for SEM demonstrated an adequate fit with the data. Volunteer motivation provides a way to enhance social problem-solving ability and self-efficacy. It also leads to better mental health by enhancing positive problem orientation and self-efficacy and by reducing negative problem orientation and avoidance style.     

Evaluation of the Effects of the Medium of Instruction on Science Learning of Hong Kong Secondary Students: Students’ Self-Concept in Science

A longitudinal study has been conducted to explore the impact of a new language policy for Hong Kong secondary schools on science learning. According to this policy, only schools that recruit the best 25% of students can teach science in English, the students' second language, while the other schools have to teach science in Chinese, the students' native language. The study involved a student cohort of 100 schools starting from S1 for three years. The outcome of science learning is conceptualized as consisting of students' achievement and self-concept in science. This paper reports the possible effects of English-medium instruction (EMI) and Chinese-medium instruction (CMI) on students' self-concept in science, as measured by students' responses to a questionnaire. Comparing with the CMI students, the EMI students showed higher self-concepts in Chinese, English and Mathematics, but a lower self-concept in science. This finding suggests that the EMI students might experience greater learning problems in science than in other subjects, probably because science learning involves abstract thinking and the mastery of scientific terminology which make a high demand on language proficiency. The EMI students showed a greater interest in learning science than the CMI students, indicating that they were more academically oriented. The EMI students, however, formed a lower perceived self-competence in science than their CMI peers, despite that they performed better in the science achievement test than many of the CMI students. This perception supports the view that using English for instruction may have negative effects on science learning. It is also consistent with the observation that the EMI students perceived science as more difficult to understand and learn than the CMI students.     

Gender differences in Brazilian street youth's family circumstances and experiences on the street

OBJECTIVES: It has been proposed that homeless street girls are more likely to be from dysfunctional families and exhibit psychological distress than homeless street boys, reflecting cultural factors that result in differential norms for male and female behavior. The current analysis examined whether male and female street youth in a mid-sized Brazilian city differed in their family circumstances and day-to-day functioning on the street. METHODS: The opportunity sample consisted of 33 male (mean age 14.3, range 10-17 years) and 33 female (mean age 14.6, range 11-18 years) street youth who participated in a sentence completion task and structured interview examining family experiences and ability to meet daily needs on the street. RESULTS: Consistent with the cultural hypothesis, girls described more negative family backgrounds than boys (e.g., they were more likely to have left home because of conflict or abuse, and reported more negative relationships with their parents). However, girls' functioning on the street was similar to, and in some cases more positive than, that of boys (e.g., fewer girls reported police violence and begging to earn money). CONCLUSIONS: The few gender differences that emerged in this study offer little support for the cultural hypothesis. The findings make sense if local factors, such as services available for male and female youth and public response to street youth, are considered. It appears that street youth differ in their experiences depending on local circumstances, highlighting the need for caution in generalizing about the situation of street youth in different countries.     

RELATIONSHIPS BETWEEN ONGOING PROFESSIONAL DEVELOPMENT AND EDUCATORS’ PERCEIVED SKILLS RELATIVE TO RtI

Widespread adoption of Response to Intervention (RtI) requires large numbers of educators to develop the knowledge and skills necessary to implement the model with fidelity. This study examined relationships between large‐scale professional development on RtI and educators’ perceived skills. Elementary educators (n = 4,283) from 34 pilot and 27 comparison schools in a southeastern state participated. Leadership teams composed of subsets of educators from pilot schools who were responsible for leading RtI implementation participated in 13 days of training across a 3‐year period. Additionally, job‐embedded coaching was provided to pilot school instructional educators. Results from multilevel models indicated that leadership team membership related to increases in educators’ perceptions of RtI skills applied to academics (π = .05; SE = .02; t[6,726] = 2.60; p < .05) and of data display skills (π = .07; SE = .03; t[6,678] = 2.45, p < .05). Educator participation at pilot schools that received job‐embedded coaching related to increases in perceptions of RtI skills applied to academics (β = .07; SE = .02; t[6,726] = 2.77, p < .05). Implications for future research on RtI implementation and the practice of providing large‐scale professional development focused on RtI are discussed.     

Historicizing Singapore cinema: questions of colonial influence and spatiality

Films produced since the 1990s revival of Singapore cinema have been interpreted through a historical backdrop consisting of the nation's rapid development, participation in the global economy and authoritarian one-party governance. Film historians have described these texts by relying on discourses associated with globalization and postmodernism. This paper finds the perspective of Singaporean films to have overlooked colonialism as a significant part of Singapore's cultural identity and argues that greater consideration of that history can not only illuminate contemporary films, but also expand film scholarship to include understudied films from Singapore's ‘golden age’ of filmmaking from the 1950s to early 1970s. The history of Singapore cinema should thus be re-periodized. By analyzing the heuristic function of colonial urbanity in films from both eras, this paper explores how spatiality provides a common thread that runs through local experience, identity, culture and cinema.     

How to quantify the transition phase during golf swing performance: Torsional load affects low back complaints during the transition phase

The transition phase of a golf swing is considered to be a decisive instant required for a powerful swing. However, at the same time, the low back torsional loads during this phase can have a considerable effect on golf-related low back pain (LBP). Previous efforts to quantify the transition phase were hampered by problems with accuracy due to methodological limitations. In this study, vector-coding technique (VCT) method was proposed as a comprehensive methodology to quantify the precise transition phase and examine low back torsional load. Towards this end, transition phases were assessed using three different methods (VCT, lead hand speed and X-factor stretch) and compared; then, low back torsional load during the transition phase was examined. As a result, the importance of accurate transition phase quantification has been documented. The largest torsional loads were observed in healthy professional golfers (10.23 ± 1.69 N · kg^?1), followed by professional golfers with a history of LBP (7.93 ± 1.79 N · kg^?1), healthy amateur golfers (1.79 ± 1.05 N · kg^?1) and amateur golfers with a history of LBP (0.99 ± 0.87 N · kg^?1), which order was equal to that of the transition phase magnitudes of each group. These results indicate the relationship between the transition phase and LBP history and the dependency of the torsional load magnitude on the transition phase.     

lol: new language and spelling in instant messaging

Written communication in instant messaging, text messaging, chat, and other forms of electronic communication appears to have generated a “new language” of abbreviations, acronyms, word combinations, and punctuation. In this naturalistic study, adolescents collected their instant messaging conversations for a 1-week period and then completed a spelling test delivered over instant messaging. We used the conversations to develop a taxonomy of new language use in instant messaging. Short-cuts, including abbreviations, acronyms, and unique spellings were most prevalent in the instant message conversation, followed by pragmatic signals, such use of emoticons, emotion words, and punctuation, and typographical and spelling errors were relatively uncommon. With rare exceptions, notably true spelling errors, spelling ability was not related to use of new language in instant messaging. The taxonomy provides an important tool for investigating new language use and the results provide partial evidence that new language does not have a harmful effect on conventional written language.
