Introduction. Broadcasting a suicide attempt on social media has become a public health concern in many countries, particularly in China. In these cases, social media users are likely to be the firstto witness the suicide attempt, and their attitudes may determine their likelihood of joining rescue efforts. This paper examines Chinese social media(Weibo) users’ attitudes towards suicide attempts broadcast on ***. A total of 4,969 Weibo posts were selected from a customised Weibo User Pool which consisted of 1.06 million active users. The selected posts were then independently coded by two researchers using a coding framework that assessed:(a) Themes,(b) General attitudes,(c) Stigmatising attitudes,(d) Perceived motivations, and(e) Desired *** and Discussion. More than one third of Weibo posts were coded as "stigmatising"(35%). Among these, 22%, 16%, and 15% of posts were coded as "deceitful", "pathetic", and "stupid", respectively. Among the posts which reflected different types of perceived motivations, 57% of posts were coded as "seeking attention". Among the posts which reflected desired responses, 37% were "not saving" and 28% were "encouraging suicide". Furthermore, among the posts with negative desired responses(i.e. "not saving" and "encouraging suicide"), 57% and 17% of them were related to different types of stigmatising attitudes and perceived motivations respectively. Specifically, 29% and 26% of posts reflecting both stigmatising attitudes and negative desired responses were coded as "deceitful" and "pathetic" respectively;while, 66% of posts reflecting both perceived motivations and negative desired responses were coded as "seeking attention". Very few posts "promoted literacy"(2%) or "provided resources"(8%). Gender differences existed in multiple ***. This paper confirms the need for stigma reduction campaigns for Chinese social media users to improve their attitudes towards those who broadcast their suicide

研究背景:社交媒体直播自杀企图现象已经在许多国家(包括中国)成为了一项新型的公共卫生问题。在众多案例中,社交媒体用户最有可能在第一时间目击到直播自杀企图行为,他们对该现象所持有的态度会直接决定其自身实际参与救援活动的可能性。本论文旨在探究我国社交媒体(新浪微博)用户如何看待社交媒体直播自杀企图现象。研究方法:本研究利用大数据技术共计下载到106万名活跃用户公开发表的全部微博内容,从中筛选出4969条微博作为分析对象。在此基础上,由两位研究者分别对4969条微博进行独立编码,并判断每条微博是否反映了不同类型的"微博主题"、"基本态度"、"污名化态度"、"实施动机推测"及"应对方式"等。研究结果:有35%的微博表示用户对社交媒体直播自杀企图现象持有消极的污名化态度;而在这些微博中,用户倾向认为实施直播自杀企图是"虚假的"(22%)、"令人鄙视的"(16%)、"愚蠢的"(15%)。在反映了"实施动机推测"的微博中,用户倾向认为实施直播自杀企图仅仅是"为博出名"(57%)。在反映了"应对方式"的微博中,有37%的微博表示应该对该现象"不予援救",有28%的微博表示应该怂恿当事人继续完成自杀行为。消极应对方式(即"不予援救"与"怂恿自杀")可能与消极的态度、错误的实施动机推测有关。而在反映了消极应对方式的微博中,有57%与17%的微博同时对应于各类"污名化态度"与"实施动机推测"。具体来说,在同时反映了"污名化态度"与消极应对方式的微博中,有29%与26%的微博表示实施直播自杀企图是"虚假的"、"令人鄙视的";而在同时反映了"实施动机推测"与消极应对方式的微博中,有66%的微博表示实施直播自杀企图仅仅是"为博出名"。此外,极少有微博的主题是"提升心理健康素养"(2%)或"提供心理干预资源"(8%)。一些编码类别在微博数量上存在着显著的性别差异。研究结论:本研究表明,急需改善我国社交媒体用户针对直播自杀企图现象的污名化态度。本研究的研究结果为如何提升我国的公共卫生服务水平提供了策略启示,并为其它面临相似问题的国家提供了有益借鉴。

Evaluation of Nutrition and Physical Activity Knowledge, Attitudes, Self Efficacy and Behaviors in Teachers and Children after Implementation of the “Healthy Active Kids” online Program in Australian Elementary Schools

引用

Health 2016年第4期8卷 293-303页

作者： Jennifer A. o’dea Faculty of Education & Social Work University of Sydney Sydney Australia

The aims were to examine change in nutrition and physical activity knowledge, self efficacy and attitudes in a cohort of 23 teachers and 304 year 5 and 6 children after the “Healthy Active Kids” online program and to assess any behavioral change in children’s self reported nutrition and physical activity behaviors and investigate the predictors of nutrition knowledge gain in teachers and children. Results found significant (p owledge of the five food groups;key nutrients provided by each food group, The Australian Guide to Healthy Eating;food labelling laws, identification of common names for fats, sugars and salts on food labels, food proportions on the Healthy Food Plate and the level and percentage of water in the human body and human brain. Teacher attitudes towards the importance of nutrition and diet and self efficacy related to teaching nutrition in class improved (p on model for predictors of the dependent variable, knowledge gain in students was R = 0.53, Adjusted R square = 0.28 (F = 4.76, p of the variation in knowledge gain was predicted by the negative (low) Time 1 knowledge. Changes to eating habits reported by children were “drinking more water each day” (89.1%) and “eating foods from the five food groups each day” (76.2%);“sharing information about food labels with your family” (52.4%);“reading food labels when you go shopping” (50.0%);“changing what is on your dinner plate each night” (44.2%);“vegetables that you eat now that you didn’t eat before” (42.1%) and “fruits that you eat now” (39%). Results suggest that the development of basic nutrition knowledge is still very important for both teachers and students, but that other factors such as self efficacy, empowerment and skill development also contribute to nutrition behavior change in children.

Alternate phenotype–genotype selection for developing superior high-yielding irrigated rice lines

Increase grain yield potential is one of the most important objectives of any cereal crop breeding program. To efficiently develop superior rice lines by the introgression of favorable alleles for yield and yield component traits, a strategy of alternate phenotype–genotype selection was used. The present study aimed to(i) investigate the allelic diversity of loci associated with major yield-component traits and(ii) phenotype and genotype advanced populations derived from crosses between NERICA-L-20 and Giza178 for yield component traits using agro-morphological descriptors and GRi SP polymorphic markers to select superior high-yielding rice lines. A total of 100 F2:3 progeny were selected from 1000 F2 plants and genotyped with 16 polymorphic markers linked to four major yield-component traits. Four promising F2:3 lines(ARS 563–14, ARS 563–62, ARS 563–286, and ARS 563–41)bearing combinations of desirable alleles were selected. A selected set of 20 F2:4 lines showed moderate to high heritability for all target traits. Fourteen F2:5 lines derived from ARS 563–14 and 17 F2:5 from ARS 563–286 families were evaluated in preliminary trials to estimate yield gain. The three top lines, ARS 563–286–16-1-1, ARS 563–286–5-1-1, and ARS563–14–10-1-1, showed an increase of more than 10% grain yield over the best check, Sahel108, which is widely cultivated in the Senegal River valley. The 16 markers linked to the target yield component traits can be used to fast-track breeding programs targeting rice productivity.

Microsatellite-Aided Screening for Fertility Restoration Genes (Rf) Facilitates Hybrid Improvement

引用

Rice science 2016年第3期23卷 160-164页

作者： Raafat El-Namaky Saber Sedeek Yonnelle dea Moukoumbi Rodomiro ortiz Baboucarr Manneh Africa Rice Center (Africa Rice) Sahel Regional Station B.P.96 Saint-Lauis Senegal Africa Rice Center (Africa Rice) P.O.Box 33581 Dar es Salaam Tanzania Swedish University of Agricultural Sciences Box 101 Alnarp SE 23053 Sweden Rice Research and Training Center (RRTC) Sakha-33717 Egypt

DNA markers enabled to determine the chromosomal locations of the two Rf genes(Rf3 and Rf4) in the wild-abortive cytoplasmic male sterility(WA-CMS) system. Four simple sequence repeats(SSRs) RM171, RM258, RM315 and RM443 were used to detect the allelic status with respect to the fertility restoration genes(Rf3 and Rf4) in 300 rice cultivars or breeding lines. The results revealed that out of 300 lines, 90 lines screened had Rf3, 65 lines had Rf4, and 45 lines had Rf3 and Rf4 alleles. Furthermore, 45 lines selected using SSR markers were mated with a CMS line(IR58025A) to analyze their restoring ability. offspring of all the test lines except HHZ8-SAL9DT1-Y1, HHZ5-SAL9-Y3-1 and IDSA77 exhibited higher pollen and spikelet fertility(> 80%), thus confirming they bear the Rf alleles. The hybrid offspring of ARH12-6-1-1-B-3-1, IR32307-10-3-2-1 and Sahel 329 had the highest pollen fertility(97.39%, 98.30% and 97.10%, respectively) and spikelet fertility(95.10%, 97.07% and 96.10%, respectively).
