A Design of Attributes Double Sampling Plans for Three-class Products

In this article, a new attributes double sampling plan for three-class products (ADSPTP) is presented, and the corresponding operating characteristic function is constructed based on the given procedure of performing ADSPTP. Average sample numbers (ASN) for complete inspection and curtailed inspection of the second sample are derived and the extreme point is discussed on the three-dimensional ASN surface. In addition, the differences arising from different parameters are studied. Sampling plans are designed by a nonlinear optimization model. Finally, numerical examples and discussions are given to illustrate the obtained results, and tables of the designed plans under various conditions are provided.     

Therapeutic Responses to Domestic Violence in Australia: A History of Controversies

This paper reviews controversies about domestic violence occurring in heterosexual relationships discussed in the Australian context by practitioners and academics and published in the Australian & New Zealand Journal of Family Therapy over the past three decades. Controversies arose in relation to the provision of therapeutic interventions for domestic violence, primarily in individual and couple counselling and group programs. After a literature review, the following controversial issues are identified: (1) the role of patriarchy: Is a patriarchal culture the main cause of domestic violence? (2) Systemic family therapy and gendered violence: Does systemic family therapy hide men's responsibility for domestic violence? (3) Therapeutic and educational interventions for domestic violence: Does therapy turn a ‘crime’ into a ‘psychological problem’? (4) Men as victims: Do both men and women perpetrate domestic violence in equal measure? (5) It takes two to tango: What part do women play in eliciting men's violence?     

Making Space for the Maid

Chinese television dramas over the past decades have seen the rise and decline of various narratives, but no other narratives speak to the emerging urban middle class's fear and anxiety more palpably than the stories of the maid. However, despite the growing popularity of the maid stories among urban viewers, most of these stories do not resonate with domestic workers themselves. How do we make sense of the growing popularity of the maid stories among urban viewers? And how do we account for the differentiated capacity to resonate and identify with the characters among viewers? These are important questions to consider if one is to understand the new cultural politics of power and social formations in post-Mao China. In this paper, I explore some of the crucial ways in which a controlling gaze is facilitated and naturalised by the visualisation of place and space in these dramas. Then, through both critical analyses and engaged ethnography, I demonstrate how two sets of controlling gaze—everyday and televisual—reinforce and justify each other. Finally, I advance the concept of “peripheral vision,” which, I show, denies the modernist “master” narrative of the city and, instead, empowers the subaltern figure with an epistemological position of “eye-witness” and anthropologist of the city.     

Foot-and-Mouth Disease Entrance Assessment Model Through Air Passenger Violations

This article aims to construct a risk model for the prediction of foot-and-mouth disease (FMD) entrance caused by passengers who illegally carry meat products of cloven-hoofed animals through international airports into a country. The risk that meat contaminated with the FMD virus is formulated as the probabilities of FMD factor events (the prevalence of FMD), the commodity factor event (the transportation, storage, and distribution (TSD) factor event), and the passenger event. Data used for analysis were records of illegal meat product carriers from areas A and B intercepted at an international airport in Taiwan. A risk model was proposed to simulate the probability distributions in disease prevalence, probability of FMD virus existing in the meat products after meat processing, and estimation of survival of virus and time period for TSD. The probability of the passenger event was hypothesized with the odds of intercepted passengers and estimated via logistic regression. The results showed that the odds of passengers being intercepted by beagles were higher than those intercepted by Customs. By conducting Monte Carlo simulations, the probability of FMD virus risk caused by FMD factors from area A was 149 times lower than that from area B. The probability of FMD virus risk caused by the passenger event from area A was four times lower than the corresponding probability from area B. The model provides a contribution to FMD prevention and can be a reference for developing models of other diseases.     

农产品网购意愿影响因素及作用机理研究——基于参照效应视角的分析

以整合型科技接受和使用模型(UTAUT)和价值接受模型(VAM)为基础,通过构建参照群体、参考价格、积极在线评论与感知价值、感知风险以及购买意愿之间的关系模型,从参照效应视角实证分析了农产品网购意愿的影响因素及作用机理,并探讨了消费者农产品质量与安全意识在参照效应影响网购意愿中的调节作用.结果表明:参照效应对农产品网购意愿有显著影响;感知价值和感知风险在参照效应影响网购意愿中均发挥了中介作用,但感知价值的中介作用显著大于感知风险;消费者农产品质量与安全意识在参照效应影响网购意愿中部分地发挥了调节效应.其中,对参照群体和积极在线评论的调节效应显著,即网购过程中,消费者越是重视农产品质量与安全,参照群体的意见和积极在线评论对其网购意愿的影响就会越凸显.     

基于农产品出口基地视角的安徽农产品出口促进体系研究

安徽省是农业大省,但是农产品出口贸易额在全国却处于相对落后水平。为促进农产品出口,安徽建立了一系列农产品出口基地。文章通过对安徽农产品出口基地的农产品出口现状进行分析,探究安徽省农产品出口支持政策的现状、找出安徽省农产品基地出口促进体系中政策所存在的问题,提出诸如加大资金扶持和指导创立培育品牌及完善农产品质量安全体系等对策。     

基于改进突变级数法的农产品物流产业评估模型研究

对农产品物流产业发展水平进行客观、准确的分析与评估,可为政府部门优化与调整产业发展、合理制定产业规划提供科学依据。运用突变级数法与离差最大化法构建农产品物流产业评估模型,并选取广东和山东两省20102014年相关数据对构建的评估模型进行实例分析。结果表明：广东省农产品物流产业发展的优势主要体现在信息化水平与经济基础两方面,基础设施建设则是当前制约其产业发展的关键因素;而庞大的产业规模是现阶段支撑山东省农产品物流产业发展的重要力量。改进的突变级数评估模型既克服了主观赋权的局限,又不失科学性和合理性,计算简单,具有重要实用价值。     

结构优化对我国农产品出口竞争力的影响

应用产业组织理论,揭示结构优化对农产品国际竞争力的作用机理。以RCA衡量农产品出口竞争力并建立多元回归模型,在有效分离工资、土地灌溉面积和汇率等因素后,实证研究发现技术结构对农产品出口竞争力有显著正向影响。当前经济背景下,提升农产品出口竞争力的政策思路,需从传统的要素禀赋优势转移到结构优化的轨道上来。优化农产品出口结构,政府需加大对高附加值农产品在生产、流通、出口等环节的支持力度,营造寡占的农产品市场结构,鼓励和扶持创意农业的发展。     

能效标识对节能产品选择的引导效用分析——基于京东家电线上销售的实证检验

搜集冰箱、洗衣机、空调三种大家电的线上销售数据,通过描述性分析、组间差异比较、多元回归分析等方式分析能效标识的市场引导效果。结果显示消费者对不同等级家电产品的选择量存在差异,但不同能效等级间消费者满意度并无明显差异,能效等级并非是影响消费者选择和满意度的显著因素。     

中国证券市场结构化产品的创新问题

作为衍生证券技术与金融工程技术相结合的产物,资产证券化在近30年来成为全球金融领域最重大而且发展最快的金融创新和金融工具。相比之下,中国证券市场在取得一定进步的同时依旧面临着诸多问题与缺陷,而金融产品单一更是主要问题之一。对国际上资产证券化和结构化产品演进历史的追溯表明,结构化产品创新是盈利多元化及业务多样化的重要因素。对我国现阶段证券市场制度环境和投资者需求的对比分析,以及对结构化产品开发成功案例的深入研究,可以看到在中国进行资产证券化更加适宜采取有选择的渐进的方式,同时积极开展结构化产品的创新研究。
