论社会转型期的新闻价值取向

中国自改革开放以来,进入了新的社会转型期,新闻传播随社会的转型而转型。转型期的新闻传播,历经几轮改革,其新闻价值取向呈现多元化、生活化、平民化、深度化等特点。"民生新闻"的兴起、经济新闻的升温、时政新闻的新变、娱乐新闻的兴盛,构成转型期新闻报道新的框架。新时期的新闻传播也发生了种种迷失。     

V_2O_5-CaCo_3-Nb_2O_5掺杂对低损耗功率Mn-Zn铁氧体的影响(英文)

1IntroductionApplication of Mn-Zn ferrites in power electronics isconstantly expanding. Demands on small and efficientswitching power supplies are rising to meet therequirement of compact and power saving electronicequipment . In a switching power supply, the trans-former takes up a large portion of cubage and powerloss .It is thereforei mportant to reduce the power lossof Mn-Zn ferrites used as the transformer core .Core loss is known to be dividable into three com-ponents :hysteresis loss …     

人类学视野下的丽江大研镇纳西语流失现状研究

文化变迁是人类学研究和探讨的永恒话题,语言是文化的主要载体,文化变迁往往首先是表现在语言变迁的基础之上。语言变迁的原因主要有政治因素、经济因素和文化因素。通过在丽江大研镇一个月的纳西语流失现状田野调查,对丽江大研镇的纳西族语言流失现状及成因作简要分析,进而对纳西语及纳西文化的传承做一些初步的探讨。     

远距离输电演示实验设计与研究

对现有的远距离输电演示仪器进行改进,自行设计和制作了远距离输电模拟实验演示仪,可从定性观察和定量计算两方面演示。这套演示仪不仅可以作为课堂演示实验教具,还可作为学生的探究性实验进行研究。     

农业非点源污染氮、磷负荷估算及经济损失评估——以福建省2010年农业非点源污染为例

利用Jones输出系数模型估算了2010年农业非点源污染总氮（TN）、总磷（TP）负荷,包括种植地、畜禽养殖、农村生活3个方面,并结合环境经济学防护费用法估算非点源总氮、总磷流失的经济损失。结果表明：TN非点源负荷中,畜禽养殖产生负荷最大,农村生活负荷产量次之,种植地产生负荷最少;TP非点源负荷中,畜禽养殖产生负荷最大;农村生活产生负荷次之,种植地产生负荷最少。农业非点源TN、TP流失经济总损失为73．323亿元,畜禽养殖流失损失占总损失的57．43％,农村生活流失损失占25．71％。种植地流失损失占总损失的16．86％。综上,TN、TP流失的控制应注意畜禽养殖和农村生活方面,其中重点为生猪、牛和家禽。     

从心理契约视角探究高科技企业的人才流失

心理契约是企业组织行为与员工彼此认同、无需条文约束的一种心灵感受与协调。心理契约违背是高科技企业人才流失的主要原因,而违背原有的心理契约往往是不可避免的,关键在于如何采取正确的措施来降低违背发生的概率。高科技企业要充分认识到心理契约在组织管理中的重要性,把这种心理契约提升到企业的人力资源战略的高度,通过构建心理契约,以更有效的手段为企业留住人才。     

光纤损耗对色散管理光通信系统中孤子传输的影响

利用virial理论和数值模拟对色散管理光通信系统中的孤子传输进行了研究.结果表明,在普通光纤与色散补偿光纤的交界处,孤子幅度不连续,其幅度有所降低,但其形状保持不变.在小损耗光纤中传输的孤子,通过放大器幅度得到放大的同时,形状将自动得到恢复,可以稳定地、长距离不变形地传输,具有理想信息载体的特性.     

王小波小说艺术中的人生之“畏”

畏是孤独、恶心、焦虑弥漫着一种无可名状的恐惧。王小波的时代三部曲《黄金时代》《白银时代》和《青铜时代》戏谑地言说了人性,展现在人生中是一种无可名状的＂畏＂,进而对人的在世价值和意义予以长长的喟叹和深刻的思考。     

再论对受赠人信赖利益损失的法律救济

为保护受赠人的利益,《合同法》将赠与合同定性为诺成性合同,以此来加强对赠与人的约束。同时,法律为实现其公平、正义的价值,平衡保护双方当事人的利益,鉴于赠与合同的单务、无偿性,特赋予赠与人以撤销权和穷困抗辩权,然而赠与人行使上述权利时有可能导致受赠人信赖利益的损失,该项损失该由谁来承担,对此,各国法律均未作出明确规定,需结合案例对其进行探讨。     

History of abuse and neglect in patients with schizophrenia who have a history of violence

Objective

To determine the prevalence of five forms of abuse/neglect during childhood and adolescence in a group of schizophrenic patients with a history of violence.

Methods

Twenty-eight patients hospitalized in a highly secured psychiatric unit were included. Abuse and neglect during patients’ growth were evaluated with the childhood trauma questionnaire (CTQ). History of substance abuse (consumption of cannabis, and/or alcohol, and/or heroin, and/or cocaine during the year that preceded the hospitalization), incarceration, and death of a close parent were also collected.

Results

We found that 46.4% of patients experienced at least 1 form of abuse and/or neglect during childhood and 21.4% of them had experienced more than 2 forms of abuse and/or neglect. The 2 most frequent forms of neglect and abuse were physical abuse (39.3%) and emotional neglect (17.9%). History of substance abuse was found for cannabis (57.1%), alcohol (57.1%), and cocaine and/or heroin (35.7%). We found that 42.8% of patients had 1 close relative who had died during their growth and that 41.6% of these deaths were violent.

Conclusion

It appears important to systematically search for and assess a history of abuse and neglect during growth in schizophrenic patients with a history of violence, in order to offer specific treatments for this group of patients.
