However, few studies have investigated children’s suicidal ideation, and longitudinal studies are particularly rare. The purposes of this study were: (1) to describe the proportion of students with suicidal ideation in one month and incidence of suicidal ideation in the 7th graders (the first year of junior high school) living in urban and rural areas; (2) to realize the influence of perceived stressors on the onset of 7th graders’ suicidal ideation; and (3) to explore possible pathways through which trigger factors and perceived stressors lead to suicidal ideation. Methods A total of 1,589 students were followed from grade 4 to grade 7. Logistic regression was then used to investigate the influence of perceived stressors on the onset of suicidal ideation in grade 7. Structural equation modeling was used to analyze possible pathways through which trigger factors led to increased pressure from certain stressors which in turn resulted in suicidal ideation. Results The proportion of students with suicidal ideation in one month was 2 to 3 times higher in both areas compared to that in elementary school. However, the incidence in the rural area showed a large increase from 10.2% and 9.5% in grades 5 and 6 to 15.5% in grade 7. Urban–rural difference was observed. Important stressors and pathways of suicidal ideation differ between urban and rural areas. Conclusions This study showed that the influential stressors in urban and rural areas might be different. Thus, interventions focused on coping skills for regional specific stressors and trigger factors could be beneficial in the transition time.Item Effects of carbohydrate combined with caffeine on repeated sprint cycling and agility performance in female athletes(2014-05-01) Lee, Chia-Lun; Cheng, Ching-Feng; Astorino, Todd A; Lee, Chia-Jung; Huang, Hsin-Wei; Chang, Wen-DienAbstract Background Caffeine (CAF) has been shown to improve performance during early phase of repeated sprint exercise; however some studies show that CAF also increases the magnitude of physical stress represented by augmented blood lactate, glucose, and cortisol concentrations during latter phase of repeated sprint exercise. No studies have investigated the efficacy of combined carbohydrate (CHO) and CAF consumption during repeated sprint exercise (RSE) in female athletes. Thus, the purpose of this study was to investigate the effects of CAF with CHO supplementation on RSE and agility. Methods Eleven female athletes completed four experimental trials performed 7 d apart in a double-blind, randomized, and counter-balanced crossover design. Treatments included CAF + PLA (placebo), CAF + CHO, PLA + CHO, and PLA + PLA. Participants ingested capsules containing 6 mg · kg−1 of CAF or PLA 60-min prior to RSE, and 0.8 g · kg−1 of CHO solution or PLA immediately before the RSE, which consisted of ten sets of 5 × 4-s sprints on the cycle ergometer with 20-s active recovery. The agility T-test (AT-test) was performed before and after the RSE. Blood samples were acquired to assess glucose, lactate, testosterone, and cortisol. Results During Set 6 of RSE, peak power and mean power were significantly higher in PLA + CHO than those in CAF + PLA and PLA + PLA, respectively (p < .05). Total work was significantly increased by 4.8% and 5.9% with PLA + CHO than those of CAF + CHO and CAF + PLA during Set 3. PLA + CHO also increased total work more than CAF + PLA and PLA + PLA did during Set 6 (p < .05). No significant differences in AT-test performance either before or after the RSE were occurred among treatments (p > .05). Blood lactate and glucose concentrations were significantly higher under CAF + CHO, CAF + PLA, and PLA + CHO versus PLA + PLA (p < .05), but no differences in testosterone or cortisol levels were found (p > .05). Conclusions Findings indicate that CAF + PLA or CAF + CHO ingestion did not improve repeated sprint performance with short rest intervals or agility. However, CHO ingested immediately prior to exercise provided a small but significant benefit on RSE performance in female athletes.Item Foreword: Speaking Existence(英語學系, 2013-09-??) Joan Chiung-huei ChangItem Darkrooms as Metaphors; Darkrooms as Origins: Michael S. Harper’s Dark Room Poems(英語學系, 2013-09-??) Andrew MillerThe article explores the poet Michael S. Harper’s use of the darkroom as a metaphor for family history and African American identity. Acknowledging that the changes in photographic technology over the last decade have spelled the end of the darkroom as the actual workspace of the photographer and as valid, contemporary metaphor for the unconscious, the article describes Harper’s 1977 selected poems, Images of Kin, as one of the last great invocations of this metaphor, and it further examines how this metaphor and its counterpart (the metaphor of the photographic negative) develop for Harper as ekphrastic models of composition.Item On the Communal Other: Collaborative Documentary Praxis in "Joyful Life"(英語學系, 2013-04-??)
