It is about inclusion! Mining online reviews to understand the needs of adaptive clothing customers

The adaptive clothing market, which focuses on the inclusive design of clothing and footwear for people with varying degrees of disability, has grown substantially in recent years. However, few scholars have sought to understand the perspectives of online adaptive clothing consumers. This study employed topic modelling, sentiment analysis and collocation analysis to discover common themes and insights emerging from online customer reviews, scraped from a third-party review platform and three retailing web sites. We utilized customer value and functional, expressive and aesthetic theories to group the results from topic modelling into key themes. Clothing function is the most frequently discussed theme in online customer reviews, followed by customer service and clothing aesthetics. Collocation analysis revealed the cause underlying each theme vis-à-vis customer satisfaction (e.g., fit and material quality) and dissatisfaction (e.g., sewing defects and lost shipment). The findings contribute to understanding the clothing needs and wants of people living with disabilities. It also provides practical guidelines on product offerings and online service optimization for adaptive clothing retailers.     

非合作信号射频域干扰抵消性能分析

针对航空测控系统面临宽带干扰时,缺乏有效的抗干扰手段的问题,研制了定向天线和全向天线的接收结构,可在射频域抵消外来的非合作信号,以保证合作信号的准确接收。并讨论了单抽头和多抽头两种结构模型。利用干扰抵消算法,以剩余非合作信号功率最小为准则,进行了理论推导。并提出在多抽头结构的工程实现中采用矢量调制器来进行幅度和相位的调整。仿真结果表明:对于单抽头结构,在2.6GHz频段,对于带宽100 MHz的信号,当延迟线长度调整误差为2%时,最优的干扰抑制能力达到了45dB,当考虑幅度调整误差为10%时,干扰抑制能力会降低约10dB;对于多抽头结构,使用与单抽头相同的信号。以双抽头为例,当传输时延差固定时,最优干扰抑制能力可达81dB,仿真结果从理论上验证了接收结构的可行性。     

Consumption coping strategies and well-being among refugee consumers

This paper aims to provide new insight into refugee consumers' adaptation to stress with a particular emphasis on consumption coping strategies and well-being. Drawing on the appraisal-coping theory, this paper proposes a theoretical framework relating stress to coping responses and refugee well-being. Social support is also introduced in the framework as a moderator. Examining the interplays between these concepts provides a comprehensive view of how changes in consumption patterns occur and how they affect refugee well-being. Insights from this paper suggest that consumption activities could be viewed as responses of adaptation to chronic and acute stress. To adapt to new circumstances and reduce their stress, refugee consumers could engage in adaptive consumption coping or maladaptive consumption coping (i.e., compulsive and impulsive consumption), which in turn affect their psychological and physical, family, and economic well-being. The paper contends that service support moderates the relationships between stress, coping responses, and refugee well-being.     

论有限责任的实现及其法律适用界限

有限责任制度适用于公司、商业信托、合伙企业等各种商业组织形态.在这些企业中,有限责任通过构建商业组织和资产分割得到实现.组织化的重要功能在于通过建立公司或商业信托构建法律实体、促成资产分割并形成独立公司财产或独立信托财产从而实现商业组织所有人的有限责任.有限责任削弱了对债权人利益的保护,容易造成利益不均衡.在有限责任制度被滥用的情况下,应适用法人人格否认、实质合并规则等制度性措施予以纠正.同时,应谨慎对待有限责任在专业服务领域的适用,强调专家严格责任.     

气候变化信息来源对农户适应性耕作行为决策的影响——来自湖北省水稻主产区的经验证据

目的 适应性耕作行为是农户应对气候变化的关键策略。文章旨在探究气候变化信息因素和信息来源对农户适应性耕作行为存在的潜在影响。方法 通过构建“气候刺激—信息干预—适应行为”理论分析框架，阐明了政府部门、科研机构和邻里交流3类典型信息来源影响农户适应性耕作行为的内在机理。在此基础上，基于湖北省水稻主产区920户稻农的样本数据对理论猜想展开实证检验。结果 （1）来源于政府部门和科研机构的气候变化信息对农户适应性耕作行为有显著的正向影响，但在同时考虑3种信息来源的情景下，科研机构信息来源对农户的适应性耕作行为的正向影响最为强烈。（2）农户在获得政府部门、科研机构和邻里交流的气候变化信息后，他们在气候变化适应性耕作行为方面差异主要取决于其气候变化认知而非主体信任因素。结论 政府部门和科研机构等为代表的正式组织的气候变化信息对农户适应性耕作行为的积极影响更为显著，但这种影响很大程度上取决于农户所获得的信息能否提高其气候变化认知。     

The practicalities of a Learning Tourism Destination: a case study of the Ningaloo Coast

The complex and dynamic nature of tourism, and the need to address triple bottom line sustainability, has encouraged a search for adaptive tourism management approaches based on organisational learning. In this paper, the authors discuss a practical approach for the implementation of a Learning Tourism Destination (LTD), a new concept derived from the theory of learning organisations. Preliminary results from a case study undertaken at the Ningaloo Coast in Western Australia are discussed. The conducted surveys indicate that the LTD forms a useful framework for fostering consensus building, dialogue and collective learning processes among stakeholders. The proposed approach has the potential to improve decision‐making within the concept of sustainable tourism development by facilitating participative planning processes. The overall strategy of this paper is to explore the practicalities of the LTD implementation process, and to spark further conceptual and practical debate, based on the analysis of the Ningaloo case study.

A dual-clustering algorithm for a robust medical grid partition problem considering patient referral

The medical grid including hospitals at all levels is a new hierarchical diagnosis and treatment system. It is assumed to provide health services for residents in a certain area, allowing free referral of patients, so as to effectively utilize medical resources. Therefore, from the perspective of the government, the key issue is how to divide the medical grid in a robust and balanced manner. In this paper, various deterministic factors, such as hospital level, location and department, as well as uncertain factors, including patient distribution or population density, are considered in decision-making. To solve this problem, a dual-clustering algorithm based on K-means and K-medoids (DCKK) is developed with local search methods to minimize the average patient waiting and travelling time. The experimental results show that DCKK algorithm can generate better and more robust grid partition solutions than the existing mainstream algorithms in different scenarios. In addition, the rules between the number of medical grids and the number of patients, as well as the hospital sharing between medical grids, are also studied. Finally, a real medical grid partition case of Ji'nan, China, with forty hospitals in four urban areas, is studied, and five medical grids are recommended.

基于生态风险评价的水网乡村适应性规划研究--以吴江三白荡片区为例

作为乡村振兴的先行区,苏南地区乡村建设发展程度较高,但过快的城镇化进程也给乡村带来了水网格局破碎、生态功能降低等问题,导致乡村面临的生态风险增加,静态的景观规划方法逐渐无法适应当前乡村生态文明发展的需求。论文以苏南乡村的地域特征为基础,选取苏州吴江三白荡北部片区的乡村为研究对象,在生态要素识别的基础上,通过景观干扰度分析和景观脆弱度分析构建生态风险评价体系,并得到研究区生态风险空间分布。依据不同风险等级经空间分异将研究区域划分为生态维育区、动态适应区和综合建设区,分别从构建生态安全格局、改善乡村适应性循环和提升乡村多情境反馈三方面提出苏南水网乡村适应性规划策略。
