Going to Pieces: Paul Monette and the Fragments of the Tribe

Author of the highly acclaimed Borrowed Time: An AIDS Memoir (1988) and winner of the 1992 National Book Award for his autobiography Becoming a Man: Half a Life Story, Paul Monette died of complications from AIDS in Los Angeles on February 12, 1995. His most recent work, Last Watch of the Night: Essays Too Personal and Otherwise (1994), is his third volume in a trilogy of autobiographical writing on growing up gay, coming-out, and living with AIDS. A graduate of Phillips Academy and Yale University, Monette received a number of awards for his writing and his work as an outspoken voice in the battle against AIDS, including the National Book Award, three Lambda Literary awards, the PEN Center West Freedom to Write Award, and three honorary doctorate degrees, from Wesleyan University, the City University of New York, and the State University of New York at Oswego. A memorial service was held for Monette on Sunday, February 19, 1995, at the Directors Guild of America on Sunset Boulevard in Los Angeles. Paul Monette was 49.     

农户病虫害统防统治服务采纳行为的影响因素——以江苏省水稻种植为例

采用嵌套Logit模型,基于江苏省病虫害统防统治试点地区630个水稻种植户的调研数据,对影响农户采纳包药防治服务与全承包防治服务的因素进行了比较分析。结果表明:在第一层次病虫害防治模式（统防统治与自防自治）采纳时,农户的病虫害防治效果认知是影响其防治模式采纳决策的重要因素。在第二层次病虫害防治方式选择时,用工补贴、宣传引导、雇工价格变异系数、服务价格、户主年龄、与农技员联系强度,对农户包药防治服务采纳决策有显著影响;用工补贴、雇工价格变异系数、户主年龄、留守劳动力人数、家庭收入水平和稻田规模,对农户全承包防治服务采纳决策有显著影响;提出应根据农户禀赋和所属地区特征提高服务供给的针对性,充分发挥村集体组织协调功能等政策建议。     

双型腔模具加热系统热传导多源项反演与实验研究

模具型腔形状各异、深浅不一,难以获得均匀的模具型腔温度场,影响了成型塑件的尺寸精度和力学特性。课题组采用基于线性叠加原理的热传导反演算 法,反求模具加热系统的热源强度;根据模具加热系统的传热机理,建立模具加热系统正演和反演问题的数学模型;设计尺寸各异的一模两腔反应成型模具,开 发多通道模温控制系统,搭建测温实验平台,测温结果表明型腔表面在同一时刻的温差均未达到行业标准;根据BMC反应成型塑料的成型工艺要求,改进模具加 热工艺,获得各热管的热源强度函数,作为热传导多源项反演的输入条件,结果表明型腔温度场达到行业标准。根据反演获得的热源强度函数,再次进行实验, 实验结果与数值模拟结果吻合较好,从而验证了基于线性热传导叠加原理的多源项反演算法对优化多型腔模具的温度场均匀性是有效的,且具有普适性。     

“学习投入”与“学习性投入”的关系辨析

“学习投入”与“学习性投入”均是以学生为主体的研究,由于两者中文相似、英文相同,容易混淆,所以有必要澄清两者间的差异及联系.研究发现两者在研究目的、理论、方法、应用及相关研究方面均有差异,但两者在研究内容、研究方法及理论基础方面又存在一定的继承性.可见,两者既有联系又有区别,学习性投入是对学习投入的发展,且其研究内容包含学习投入.     

论滩头手工抄纸的传承保护与创新发展

作为一项凝聚了民间智慧的传统技艺,滩头古法手工抄纸在传承地域文化、寄托民族情愫等诸多方面,具有工业造纸所不可替代之处。在手工技艺日渐式微的时代背景下,应把生产性保护与“活态”传承结合起来,传承与创新并举,通过发展来促进保护,实现滩头手工抄纸文化与经济价值的提升,使这一传统技艺在新的时代得到真正的保护与传承。     

加强大学生媒介素养教育的基本逻辑与现实路径

网络化已成为大学生的一种生存方式,但网络媒介的双重属性决定了它对社会生活的负面效应不可避免,引导大学生适应媒介化社会生活势在必行。新时期加强大学生媒介素养教育的逻辑起点在于：网络行为异化造成大学生社会角色迷失及其人格支离破碎;网络行为约束机制缺失冲击着大学生网络道德构建;网络媒介负外部性侵蚀着大学生身心健康。加强大学生媒介素养教育、构建立体化媒介素养教育模式,应着力于培育大学生的媒介伦理素养与主体意识,增强责任意识,理性使用网络媒介;大力强化教育管理者的网络媒介素养,提升实践育人能力,发挥协同效应;全力优化网络生态,降低网络环境对媒介素养教育的影响的风险。     

Moving in or Breaking Up? The Role of Distance in the Development of Romantic Relationships

Most romantic relationships start with a living apart together (LAT) phase during which the partners live in two separate households. Over time, a couple might decide to move in together, to separate, or to remain together while maintaining their nonresidential status. This study investigates the competing risks that partners in a LAT relationship will experience the transition to coresidence or to separation. We consider the amount of time LAT partners have to travel to see each other to be a key determinant of relationship development. For our statistical analyses, we use seven waves of the German Family Panel Pairfam (2008/2009–2014/2015) and analyze couples in the age group 20–40 years. We distinguish between short-distance relationships (the partners have to travel less than one hour) and long-distance relationships (the partners have to travel one hour or more). Estimating a competing risks model, we find that couples in long-distance relationships are more likely to separate than those living in close proximity. By contrast, the probability of experiencing a transition to coresidence is lower for LAT couples in long-distance than for those in short-distance relationships. Interaction analyses reveal that distance seems to be irrelevant for the relationship development of couples with two nonemployed (unemployed, in education or other inactive) partners.     

在线信息交互的时间特性研究

在线信息交互行为的特征研究有助于完善对人类行为动力学规律的理解,为在线信息服务及管理提供理论依据.首先,利用重标极差法计算话题讨论中时间间隔序列的Hurst指数及V统计量,发现各种话题时间间隔序列Hurst指数均大于0.5,V统计量曲线呈上升趋势,表明序列具有自相似和长程相关的分形特征;然后,分析了序列V统计量趋势转折点与Hurst指数的关系,发现Hurst指数越大的序列,转折点越靠后,即序列的非循环周期更长.研究结果为分析在线信息交互行为及预测新的参与行为的到达,制定基于时间特性的舆论监管策略等提供了新的思路和方法.
