Uncovered and disrespected. A qualitative study of Jordanian women’s experience of privacy in birth

BackgroundPrivacy is related to a person’s sense of self and the need to be respected and it is a key factor that contributes to women’s satisfaction with their birth experiences.AimTo examine the meaning of privacy for Jordanian women during labour and birth.MethodA qualitative interpretive design was used. Data were collected through face-to-face semi-structured interviews with 27 Jordanian women. Of these women, 20 were living in Jordan while seven were living in Australia (with birthing experience in both Jordan and Australia). Thematic analysis was used to analyse the data.ResultsThe phrase ‘there is no privacy’ captured women’s experience of birth in Jordanian public hospitals and in some private hospital settings. Women in public hospitals in Jordan had to share a room during their labour with no screening. This experience meant that they were, “lying there for everyone to see”, “not even covered by a sheet” and with doctors and others coming in and out of their room. This experience contrasted with birth experienced in Australia.ConclusionsThis study explicates the meaning of privacy to Jordanian women and demonstrates the impact of the lack of privacy during labour and birth. Seeking a birth in a private hospital in Jordan was one of the strategies that women used to gain privacy, although this was not always achieved. Some strategies were identified to facilitate privacy, such as being covered by a sheet; however, even simple practices are difficult to change in a patriarchal, medically dominated maternity system.     

大数据在重大行政决策中的应用及其法治化

大数据在重大行政决策领域的应用，属于技术理性与决策规则的有机融合。凭借信息来源与技术革新，大数据可赋予传统决策向数字化转型的新动能。大数据的应用贯穿于重大行政决策始终，在市场监管、环境保护等多类事项中所发挥的实践优势较为明显，能够推动决策的高效化、提升决策的精准度、增强决策机关之间的联动。然而，大数据应用可能会引发决策安全的隐忧、个人数据存在的空间被挤压以及决策失误的责任承担等难题。对前述问题提出对策的过程，实乃数据治理向治理数据的转变，此阶段不能欠缺法律法规的引导，应尝试从决策数据安全体系的法治保障、个人数据的法律保护、决策责任追究机制的科学建构等层面去推动大数据应用的法治化。     

ECM-IS视角下移动政务APP用户持续使用意愿影响因素研究

Defender–Attacker Games with Asymmetric Player Utilities

The presence of strategic attackers has become an important factor in the security and protection of systems, especially since the 9/11/2001 attacks, and considerable efforts have been dedicated to its study. When defending against the strategic attacker, many existing studies assume that the attacker would seek to minimize the defender's utility, which implies that the defender and attacker have symmetric utilities. However, the attacker's objective is determined by its own valuation of the system and target of the attack, which is not necessarily consistent with the defender's utility. If the attacker unexpectedly targets a different utility, then the defense strategy might no longer be optimal. In particular, the defense strategy could be inferior if the attacker's utility is not known to the defender. This study considers a situation where the defender's utility is the system survivability and the attacker's utility is the expected number of destroyed elements in the system. We investigate possible attack strategies under these two different utilities and compare (a) the conservative defense strategy when the attack utility is unknown to the defender with (b) the optimal defense strategy when the attack utility is known to the defender. We show that the conservative protection strategy is still optimal under asymmetric utilities when the contest intensity is smaller than one.     

中国养老金:制度变革、问题清单与高质量发展

中国养老金制度经过近30多年来的深刻变革,从自我封闭的单位保障制走向开放式的社会保险制、从少数人的专利发展成为全体老年人的共同福祉、从单一责任主体走向多方分担责任、从单一层次走向多层次化,成为惠及所有老年人的社会保障制度,符合全球养老金制度发展的潮流与客观规律。但目前存在的理论认识误区、制度不统一、政策参数僵化、补充层次缺失及其导致的筹资失衡、待遇不公、预期紊乱、可持续性弱化和社会风险累积等问题正在日益显性化。这表明其仍是质量不高的制度安排。因此,中国养老金制度亟待走出逻辑混乱的思维定势与传统的路径依赖,通过明确公平建制理念、加快制度统一步伐、调适筹资责任分担机制、赋予相关参数弹性空间、理性推动多层次化等举措来为参与主体各方提供清晰稳定的预期,实现制度定型和高质量发展。     

价值链网络结构范型下社区公共物品协同供给创新

社区公共物品供给治理本质上是一个开放演化、利益关联、耦合自洽和情境适应的复杂网络系统。由于供给手段智慧化、供给过程复杂性、个体能力失败和主体关系不确定性，传统由单中心主导的分立、单一和线性供给模式不能对整体网络化供给问题给出有效释义和策应方案，需要引入价值链网络结构治理新范式。从价值链理论出发，社区公共物品供给是适应协同供给的价值链网络结构系统，价值链网络系统理论与社区公共物品协同供给具有内在契合性。价值链网络结构范型下社区公共物品协同供给的内在要求体现在现实问题逻辑、供给价值诉求和主体关系博弈三方面；价值系统表征为克服供给碎片化、提供“三变”供给路径和技术手段嵌入支撑；构建基础体现在良好的社区文化、坚实的网络基础和规范的政治环境。建构多中心价值链网络协同供给模型，需要从管理协同、运作协同以及消费反馈协同三个层面展开施加管控。     

Optimization problems for consecutive-2-out-of-n:G system

Abstract

This paper considers the optimization problems for a consecutive-2-out-of-n:G system where n is considered to be fixed or random. When the number of components is constant, the optimal number of components and the optimal replacement time are discussed by minimizing the expected cost rates. Furthermore, we focus on the above discussions again when n is a random variable. We give an approximate value of MTTF and propose the preventive replacement policy, respectively.     

Applying a Treatment Effects Model to Investigate Public Amenity Effect on Physical Activity of the Elderly

The increasing elderly population puts significant health, economic, and social burdens on society. Physical activity is one of the most cost-effective ways to maintain the health of the elderly. This study adopts a treatment effects model to investigate the causal relationship between environment attributes and physical activity among the elderly, while taking endogeneity into account. The data were collected from 274 participants by face-to-face interviews in Taichung, Taiwan. Performing physical activity regularly in parks is the most important measure of the amount of physical activity by the elderly. Providing sufficient and accessible parks in metropolitan residential neighborhoods could be one of the most cost-effective ways to promote physical activity for the elderly living in midsize Asian cities.     

Toward General Principles for Resilience Engineering

Maintaining the performance of infrastructure-dependent systems in the face of surprises and unknowable risks is a grand challenge. Addressing this issue requires a better understanding of enabling conditions or principles that promote system resilience in a universal way. In this study, a set of such principles is interpreted as a group of interrelated conditions or organizational qualities that, taken together, engender system resilience. The field of resilience engineering identifies basic system or organizational qualities (e.g., abilities for learning) that are associated with enhanced general resilience and has packaged them into a set of principles that should be fostered. However, supporting conditions that give rise to such first-order system qualities remain elusive in the field. An integrative understanding of how such conditions co-occur and fit together to bring about resilience, therefore, has been less clear. This article contributes to addressing this gap by identifying a potentially more comprehensive set of principles for building general resilience in infrastructure-dependent systems. In approaching this aim, we organize scattered notions from across the literature. To reflect the partly self-organizing nature of infrastructure-dependent systems, we compare and synthesize two lines of research on resilience: resilience engineering and social-ecological system resilience. Although some of the principles discussed within the two fields overlap, there are some nuanced differences. By comparing and synthesizing the knowledge developed in them, we recommend an updated set of resilience-enhancing principles for infrastructure-dependent systems. In addition to proposing an expanded list of principles, we illustrate how these principles can co-occur and their interdependencies.     

现代汉语感官动词语法功能相容度分析

词的语法功能属性与词的使用频度之间的关系是汉语词义属性研究的一个重要方面。通过对258个现代汉语感官动词的使用频度进行封闭测查,考察各个动词在语料库中的频次,以及各词感官义项、非感官义项、感官用法、非感官用法的使用频次,再将这些词的频度信息与它们的语法属性信息进行相容度分析,对词频与基本功能之间的关系进行描写和阐释。结果表明,感官动词的语义属性与动词语法功能之间存在不同的相关性表现。感官动词词义的特殊性表现在相对普通动词而言较弱的动作性,以及词义一般包含较强的对行为方式状态的描述,这是由感官活动在人类行为中的特殊性决定的。此外,词语的类聚特征越丰富,词语聚合的总量就越小,词语间就具有更高的相似度,这些相似度必然会在语法功能等方面得到反映。
