基于属性水平的品牌来源国作用机制研究——信息处理的视角

制造和质量控制技术在全球范围的转移,导致制造国影响减弱,这对传统原产地研究提出了新的挑战。本研究在区分品牌来源国和产品制造国的基础上,通过把产品属性划分为搜索属性和信任属性,探索品牌来源国如何在属性评价层面上影响消费者。本研究发现,品牌来源国主要在信任属性上影响消费者对产品的评价。不仅如此,与新手型消费者相比,专家型消费者评价信任属性时更多地受到品牌来源国刻板印象的影响。     

企业能力、竞争强度与对外直接投资动机——基于重庆摩托车企业的多案例研究

本文运用多案例研究方法,选取四家重庆摩托车企业的八次对外直接投资案例,对企业能力、竞争强度如何影响企业对外直接投资动机的形成进行了探讨.研究发现,我国摩托车企业的对外直接投资动机主要表现为寻求海外市场.当企业不具备技术相关能力和市场相关能力的相对优势,面临竞争者增多、价格竞争增强的情况时,企业容易产生防御型市场寻求的对外直接投资动机,并且如果主要竞争者已在目标市场投资,更容易促发企业形成这类动机.当企业具备技术相关能力和市场相关能力的相对优势,同时又面临竞争者增多、价格竞争增强的情况时,企业容易产生进攻型市场寻求的对外直接投资动机,并且如果主要竞争者尚未在目标市场投资,更容易促发企业形成这类动机.

Balancing Revenues and Repair Costs under Partial Information about Product Reliability

We consider the problem faced by a company selling a product with warranty and under partial information about the product reliability. The product can fail from multiple failure types, each of which is associated with an inherently different repair cost. If the product fails within the warranty duration, then the company is required to pay the repair cost. The company does not know the probabilities associated with different failure types, but it learns the failure probabilities as sales occur and failure information is accumulated. If the failure probabilities turn out to be too high and it becomes costly to fulfill the warranty coverage, then the company may decide to stop selling the product, possibly replacing it with a more reliable alternative. The objective is to decide if and when to stop. By formulating the problem as a dynamic program with Bayesian learning, we establish structural properties of the optimal policy. Since computing the optimal policy is intractable due to the high dimensional state space, we propose two approximation methods. The first method is based on decomposing the problem by failure types and it provides upper bounds on the value functions. The second method provides lower bounds on the value functions and it is based on a deterministic approximation. Computational experiments indicate that the policy from the first method provides noticeable benefits, especially when it is difficult to form good estimates of the failure probabilities quickly.     

Linking perceived organizational support with employee work outcomes in a Chinese context: Organizational identification as a mediator

Perceived organizational support (POS) is viewed as an important explanatory framework for understanding the relationship between employees and the workplace, and is regarded by some researchers as central in understanding job-related attitudes and behaviors of employees. However, less research has taken into account the role of organizational identification, which reflects how individuals define the self with respect to their organization, as a potential influence on such relationships. Drawing on a cross-organizational sample of 238 subordinate-supervisor dyads from the People’s Republic of China, we examined whether organizational identification mediates the effect of perceived organizational support (POS) on work outcomes including turnover intentions, work performance, and organizational citizenship behavior (OCB). Results from the current study showed that organizational identification fully mediates the relation of POS to OCB-directed to individuals, and partially mediates relations between POS and other work outcomes (turnover intention, work performance, OCB-directed to organization). Implications for management theory and practice are discussed.     

恩施烟地土壤和烤烟团棵期硒含量与分布的研究

对湖北省恩施市几个主要产烟区的烟地土壤的调查分析和对烤烟盆栽试验结果的分析表明,烟地土壤含硒量因土壤母质而异,并与土壤有机碳含量呈正相关,其分布随土壤深度增加而减少;烤烟团棵期含硒量随土壤含硒量和土壤施硒量的增加而增加,并呈现出地下部分大于地上部分的分布规律。     

2,3──二氨基吩嗪光谱特性研究及应用

研究了各种介质中不同酸度对2,3──二氨基吩嗪（DAP）的光谱特性的影响,发现非离子表面活性剂以及极性有机溶剂对其荧光具有强烈的增敏作用,荧光量子产率大大提高,而且强极性有机溶剂在无水环境下,对其荧光增敏比非离子表面活性剂更强。建立了有机介质和非离子表面活性剂介质荧光增敏的测定方法,并对各种介质增敏机理进行了讨论。

欧洲债务危机的主要成因分析

肇始于希腊的欧洲债务危机到目前为止都没有停息的迹象,甚至还呈蔓延之势。欧洲债务危机爆发的直接原因是在金融危机的背景下,政府支出规模持续扩大,导致财政赤字居高不下,最终使得国债规模超过政府的偿还能力,出现明显的违约可能性。同时,国际竞争力不足,导致出口受阻,使得资金问题更加严重。从更深层次看,产业结构不合理,经济发展速度缓慢,过低的投资率和储蓄率及过高的储蓄投资转化率,都是导致欧债危机的重要原因。
