Schema strength,processing opportunity,and the rewarding nature of incongruity resolution in advertising

Extant literature calls for more research to identify the boundary conditions as well as the process underlying the effects of ad messages that violate specific brand beliefs. This paper examines different levels of ad–brand incongruity, considering brand schema strength and processing opportunity as factors that influence the perception and the resolution of incongruity. Moreover, it provides empirical evidence for the process mediating attitudinal responses to ad–brand incongruity. Experiment 1 shows superiority for moderately incongruent ads over congruent and extremely incongruent ads which is eliminated when participants have a weak, as opposed to a strong, brand schema. Experiment 2 replicates the nonmonotonic pattern for strong, real brands but further shows that low processing opportunity favors congruent ads. Mediation analysis reveals that the psychological satisfaction experienced during the ad interpretation process has an asymmetric mediating effect, such that moderate levels of ad–brand incongruity generate highest levels of satisfaction which then leads to more positive responses.     

A profit-maximization location-capacity model for designing a service system with risk of service interruptions

This paper considers the design of an immobile service system in which each facility’s service process is subject to the risk of interruptions. The location-capacity decisions and allocations are simultaneously made to maximize the difference between the service provider’s profit and the sum of customers’ transportation and waiting costs. An efficient Lagrangian-based solution algorithm is developed, which solves large-sized instances with up to 50 service facilities and 500 customers in a few seconds. Several sensitivity analyses and managerial insights are presented. The model is also applied to a case study on a logistics network design problem in the zinc mining industry.     

Public Provision of Private Goods,Self‐Selection,and Income Tax Avoidance

Redistributive taxation should benefit those with low earnings capacity rather than those who choose a lower income to obtain tax savings. Several contributions have highlighted how public provision of work complements can discourage people from lowering labor supply to diminish taxable income. We show how tax avoidance, previously neglected, can alter the conclusions regarding public provision. Tax avoidance breaks the link between labor supply and reported income. An agent reducing his reported income to escape taxes might no longer forego a publicly provided labor complement, because he can now lower his income by avoiding more rather than working less.     

养老建筑室内建筑环境的构建——以某市社会养老服务中心为例

养老地产在我国是一项新兴产业,作为该类建筑中的一个重要组成部分——供暖、通风与空气调节工程,其设计合理与否,对于居住环境和老年人身体健康的影响至关重要。设计人员为了力求打造一个更为适合老年人居住的建筑环境,结合具体工程,做了较为细致的探讨。文章对工程设计方案,包括采暖、空调方式,室内空气质量的控制,气流组织,工程材料选择,振动噪声控制,共五大方面,逐一作了介绍。     

广东省农村基础设施建设与农业经济增长的关系探究

作为提高农业生产效率、改善农民生活质量及促进农村经济增长的重要物质基础,农村基础设施建设对扩大农村地区内需增长点,解决农村剩余劳动力就业问题以及全面推进城乡统筹发展具有至关重要的意义。广东省作为我国南部地区经济发达省份,具有丰富的农业生产自然资源,但其农村基础设施发展程度相对来说却比较低,其成为农村经济发展的"瓶颈",不利于农村经济结构优化升级。为了保障农村基础设施的供给与农村经济发展水平保持协调一致,文章以广东地区农村为例,采用多元非线性回归分析的方法,在论证农村基础设施建设对农村经济增长的作用机制的基础上,从农村基础设施建设与农业生产、非农生产和农民人均纯收入3方面的内在关系进行计量分析,结果表明,首先农村基础设施对影响农业经济增长的3方面因素都发挥了显著的规模经济效益;其次农村基础设施建设中的教育变量对农业经济增长的作用最为显著;再次,农业机械设施在农业生产中的作用相对于其他影响因素而言不太显著;最后,道路、通讯设施对非农生产和农民人均收入收入的贡献率相对其他变量数值较低。并提出健全农村基础设施建设投融资机制、加大农村基础设施的资金投入力度、提高农村基础设施建设和利用水平、全面推进农村基础设施建设进程等优化策略。     

高管政治背景与民营企业综合税负——基于政治关联的非线性影响研究

民营企业通过与政府建立良好的关系获得与国有企业同等待遇,税负是其中重要的一个方面。现有研究从线性的角度分析了政治关联对民营企业税负的影响,实际上,不同政治关联度对税负的影响方向是不同的。以2009-2011年沪深两市A股主板民营上市公司为样本,探讨政治关联是否影响企业税负以及政治关联度的变化对企业综合税负率的影响。研究发现,政治关联有助于降低民营上市公司综合税负率,且政治关联度与综合税负率之间存在倒U型关系。研究还进一步确定了政治关联度的拐点,为政府规制政策的制定提供参考。     

Reformulating Environmentally Constrained Traffic Equilibrium via a Smooth Gap Function

Various government laws have recently been enacted to alleviate the environmental deterioration of transportation systems. Environmental constraint is a valid means to explicitly reflect various environmental protection requirements imposed by the government. In this paper, we examine the environmentally constrained traffic equilibrium problem (EC-TEP), which is a fundamental tool for modeling and evaluating environmental protection requirements. Specifically, we provide an equivalent reformulation for the EC-TEP. The proposed reformulation adapts the concept of gap function to simultaneously reformulate the nonlinear complementarity conditions associated with the generalized user equilibrium conditions, environmental constraints, and conservation constraints as an equivalent unconstrained optimization problem. This gap function reformulation has two desirable features: (1) it can handle a general environmental constraint structure (linear or nonlinear; link-based or area-based) and a general link and route cost structure, enhancing the modeling adaptability and flexibility; (2) it is smooth and unconstrained, permitting a number of existing efficient algorithms for its solution. A gradient-based solution algorithm with a self-regulated averaging stepsize scheme is customized to solve the reformulated unconstrained optimization problem. Numerical examples are also provided to demonstrate the modeling flexibility of the proposed EC-TEP reformulation.
