杜甫《登高》诗中的乐观主义精神探微

杜甫写于唐大历二年(767年)秋天的《登高》诗,虽是其晚年凄凉与孤独生活状态的真实写照,但诗中却充满着令人激动的气势.这种气势不仅源于杜甫对登高文学传统的继承,亦是其晚年面对迁逝之感时昂扬生命意识的展现.除了感时伤事,诗中还深刻蕴含着杜甫晚年的壮阔情怀以及乐观主义精神,这种精神与夔州相对安定的生活有着密切关联,更是其儒家思想的重要体现.     

基于FESA/TRIZ的机械产品创新设计方法

机械产品的设计一直注重于市场需求和产品功能的开发，随着科学和技术的发展，环境因素变得越来越重要。 提出一种基于功能一环境一结构分析( FESA)与TRIZ的机械产品创新设计方法，通过分析机械产品结构之间的功能要素 以及功能要素与环境要素的相互作用关系，确定机械产品中存在的问题。建立根原因模型图，寻找结构设计上的不足和 缺陷，利用TRIZ创新理论来实现机械产品的改进创新。通过污水处理系统的创新设计实例验证了该方法的可行性。     

Pathways from workplace flexibility to turnover intention: Role of work–family conflict,family–work conflict,and job satisfaction

This study examined the prevalence of workplace flexibility and the mechanisms that allow workplace flexibility to influence turnover intentions through work–family and family–work conflicts and job satisfaction among low‐wage workers in South Korea. Participants included 250 low‐wage workers whose monthly salary was less than 2 million Korean won (approx. $1,900). The study results indicate that low‐wage workers have limited access to workplace flexibility and that workplace flexibility plays a significant protective role in reducing their turnover intention, indirectly by decreasing work–family conflicts and enhancing job satisfaction. This article also discusses the implications of these findings for labor policy and social work practice.     

新中国成立初期马克思主义在新疆地区的传播(1949—1955年）

新中国成立初期,马克思主义在新疆地区的传播,历经了从边缘走向中心、从隐蔽走向公开,进而发展为常态化的历史过程。这一过程,蕴涵着马克思主义理论的内在诉求,是中国共产党执政的在场体现,也深度契合了新疆地区各族人民的迫切需求。面对传播过程中出现的话语、文本和媒介等现实问题,党和政府通过加强党组织建设以建构话语路径、翻译出版经典著作以建构文本路径、完善本土大众传媒以建构媒介路径等来化解问题,从而为新疆维吾尔自治区成立奠定了思想与理论基础,强化了中国共产党在新疆地区的组织建设,也推进了本土传播媒介的发展与提升,更为马克思主义在民族地区传播的理论探究提供了现实参考。     

莎士比亚作品中所体现的同性取向倾向探究——以《威尼斯商人》与十四行诗为例

莎士比亚作为文艺复兴时期杰出的戏剧家和诗人,在欧洲文学史上占有重要的地位,由于莎士比亚的文学地位,使得学术界多以一种崇拜的眼光去解读其作品,而其作品中一些细微之处流露的情绪却很少被人们发觉。男同性恋文学的书写在莎士比亚的作品中对这一命题的表现的十分隐晦,通常欲言又止,但我们还是可以在其作品中发现一些蛛丝马迹。本文旨在通过分析其作品《威尼斯商人》与《莎士比亚十四行诗》来对其作品中所体现的同性化创作倾向与其同性取向倾向进行一些探究。     

湘鄂川黔革命根据地的“扩红运动”及其历史与现实意义

湘鄂川黔革命根据地是长江南岸的最后一块红色根据地,是在全国其他各路红军离开原有根据地后,由红二、六军团会师后建立的,为我国革命战争的胜利起到了不可忽视的作用。文章以"扩红运动"为研究维度,从三个方面进行深刻论析。面对国民党的"围剿"、根据地内反动势力的迫害以及薄弱的地方武装力量,"扩红运动"的组织发动显得迫切需要。"扩红运动"的组织发动不仅对打击封建反动势力、维护苏维埃政权、壮大革命队伍、策应红军长征,以及保卫土地革命成果、扩大中国共产党的影响有着重要的历史意义,而且还对当今密切党群关系、处理民族关系、加强军队建设等都有着重要的现实意义。     

医疗需求与中国医疗费用增长——基于城乡老年医疗支出差异的视角

在人口老龄化和老年医疗支出城乡差异凸显的背景下,中国医疗费用增长部分源于合理的健康需求。利用中国营养与健康调查1991—2011年的八轮数据,构造出生组跟踪样本,分别考察城乡居民医疗支出的年龄效应,估算城乡老年医疗需求导致的费用上涨,可以发现:城市居民的人均医疗支出随年龄显著增加,但农村居民的人均医疗支出随年龄增长的趋势并不明显。而忽略出生组效应,会低估城乡老年医疗支出的差距。城乡老年医疗支出差距缩小,将导致医疗费用在2010—2030年年均实际增长约5.2%。在控制医疗总费用上涨的同时,医疗保险制度需根据老年医疗需求,调整医疗资源配置结构。     

Environmental Justice in the Context of Scientifi Uncertainty: On the Safety of Genetically Modifi Organisms

应对风险特别是科学不确定性所导致的风险，实现和维护环境正义是当今时代的 一个前沿核心议题。转基因生物安全为代表的科学不确定性背景下的环境正义，需要 建立在相应的科学研究基础之上，但在本质上乃是一种社会构建。对转基因生物技术 及其产品等现代科技的研发、应用和推广等活动，应当维护其市场自由，与此同时， 为了公共安全以及社会弱势群体的最大利益，还应当对相关科技活动进行必要的政府 干预和法律规制。     

Integrating Operational and Organizational Aspects in Interdependent Infrastructure Network Recovery

Managing risk in infrastructure systems implies dealing with interdependent physical networks and their relationships with the natural and societal contexts. Computational tools are often used to support operational decisions aimed at improving resilience, whereas economics‐related tools tend to be used to address broader societal and policy issues in infrastructure management. We propose an optimization‐based framework for infrastructure resilience analysis that incorporates organizational and socioeconomic aspects into operational problems, allowing to understand relationships between decisions at the policy level (e.g., regulation) and the technical level (e.g., optimal infrastructure restoration). We focus on three issues that arise when integrating such levels. First, optimal restoration strategies driven by financial and operational factors evolve differently compared to those driven by socioeconomic and humanitarian factors. Second, regulatory aspects have a significant impact on recovery dynamics (e.g., effective recovery is most challenging in societies with weak institutions and regulation, where individual interests may compromise societal well‐being). And third, the decision space (i.e., available actions) in postdisaster phases is strongly determined by predisaster decisions (e.g., resource allocation). The proposed optimization framework addresses these issues by using: (1) parametric analyses to test the influence of operational and socioeconomic factors on optimization outcomes, (2) regulatory constraints to model and assess the cost and benefit (for a variety of actors) of enforcing specific policy‐related conditions for the recovery process, and (3) sensitivity analyses to capture the effect of predisaster decisions on recovery. We illustrate our methodology with an example regarding the recovery of interdependent water, power, and gas networks in Shelby County, TN (USA), with exposure to natural hazards.
