西方公共电视的节目评估:收视率悖论

在经营和编辑上试图独立于政府控制和商业影响的西方公共电视系统在评估节目时面临着使命与效率的冲突。收视率依然是公共电视系统在判定理想节目时的关键指标 ,但是并不是唯一的“指南针” ,各公共电视系统往往是综合使用收视率和收视质的表现评估节目价值。     

纳米氢氧化镁合成及用于含铬废水处理的研究

用乙醇作分散剂,共沉淀法合成了纳米氢氧化镁。并用XRD、SEM等技术手段对样品作了表征。结果表明,制备的样品粒径分布均匀、团聚程度小,大小在200 nm左右。同时研究了纳米氢氧化镁用于含铬废水的处理,得到较好的效果,5 min时已经基本吸附完全,最大吸附量达到了102 mg/g,是普通氢氧化镁的2.5倍;回收后的氢氧化镁经焙烧后,可以多次用于含铬废水的处理。     

数字图书馆信息技术与人文精神的融合

在信息技术冲击下,数字图书馆在建设中出现了重技术、轻人文的现象,这有悖于图书馆的价值取向。本文在论述数字图书馆信息技术与人文精神融合的必然性后提出,只有促进两者实现高度融合,数字图书馆才能充分体现人文价值,实现可持续发展。     

Food attitudes in female athletes: association with menstrual cycle length

The aim of this study was to examine the relationship between indicators of risk of disordered eating, body image and varied menstrual cycle lengths. Altogether, 151 female athletes were invited from 16 sports and 70 female non-athletic controls were recruited from a university lecture class. The participants completed several surveys, including demographics, menstrual cycle history, physical activity, Eating Disorder Inventory (EDI) and the Three Factor Eating Questionnaire (TFEQ). Selected EDI subscales were summed to reflect eating disorder risk and body image. Menstrual cyclicity was based on self-reported cycle length for the last 6 months (normal cycles = 26-32 days, irregular cycles < or =26 or >32 days). Athletes overall had more irregular cycles (29.1%) than the non-athletes (15.7%) (P < 0.05). There were significant differences in scores for eating disorder risk, body dissatisfaction, drive for thinness, cognitive restraint (TFEQ) and disinhibition (TFEQ), only when athletes were divided based on menstrual cyclicity (i.e. irregularly cycling athletes had higher scores than athletes with normal menstrual cycle lengths). No differences in these scores were found between non-athletes with normal or irregular menstrual cycle lengths. In conclusion, irregularly short or long menstrual cycle length is associated with subtle indications of higher risk of disordered eating in female athletes.
