基于电子舌传感技术评价不同市售啤酒滋味品质

应用电子舌传感技术和多元统计学方法相结合的手段,本研究对市售6个啤酒品牌下15个样品的滋味品质特征进行综合评价分析。结果表明,评价啤酒品质的8种滋味指标可以划分为三大类,其中第一主成分由酸味、鲜味和鲜味的回味组成;第二主成分由苦味和苦味的回味组成;第三主成分由咸味、涩味和涩味的回味构成。因子分析发现综合得分排名前三的啤酒样品分别为C_1、F_1和E_1。与此同时,通过聚类分析可以将15个不同品牌与类型的啤酒样品按照滋味品质的差异情况分为5类,与现有啤酒市场行情相符。研究说明电子舌传感技术在啤酒品牌区分、品质口感判定和市场分析中具有巨大的应用潜力。     

Inter-firm collaboration in new product development in Chinese pharmaceutical companies

High-tech firms increasingly rely on inter-firm collaboration (IFC) in new product development (NPD). While there is a growing research interest in exploring the economic rationale of IFC through the transaction cost economics (TCE) and the resource synergy of IFC through the resource-based view of the firm (RBV), little attention has been given to the institution-based view (IBV) that also has important implications for firms’ choice of IFC. In particular, how national institutional environment affects IFC in the NPD process remains under-researched. This study aims to contribute to the literature by extending our understanding of the role of IFC in firms’ NPD process, taking into account transactional, resource, and institutional factors. Based on a case study of two firms: a state-owned and a private pharmaceutical firm in China, our research identifies three key forms of IFC, which are dynamic at different stages of NPD and contingent upon an array of institutional, resource, and transactional rationales underpinning firms’ choice of different forms of IFC. Our study is the first one that investigates the role of IFC in the NPD process bringing together the IBV, RBV, and TCE perspectives.

Individual and Institutional Investors’ Response to Earnings Reported by Conservative and Non‐Conservative Firms: Evidence from Chinese Financial Markets

In this study, we document that there are significant differences in individual and institutional investors’ perception and interpretation of information based on accounting conservatism, as reflected by their trading behavior in the Chinese financial market. Our findings show that institutional investors, who are more sophisticated and have better skills, engage in higher purchases of equities of firms that use high accounting conservatism compared to the firms that use low/no accounting conservatism. Institutional investors’ equity purchases are even higher if these firms are associated with higher growth opportunities. On the other hand, individual investors are attracted more by the attention‐grabbing events and are motivated to purchase equities of firms that either do not use accounting conservatism or use low accounting conservatism, and their purchases are even higher when the firms report positive earnings surprises. Additionally, we find that abnormal returns are higher for the firms using high accounting conservatism and have experienced higher purchases by institutional investors.

The Impact of Occupational Community on the Quality of Internal Control

Senior executives in major corporations have drawn attention in recent years for a range of unethical activities. Despite a rise in measures to protect against such lapses, executives still make decisions whether or not to comply with reporting standards, best practices, industry norms and legislation. The prior literature in this area addresses individual characteristics of decision makers and social networks between executives and boards of directors, but to this point has largely overlooked group dynamics of the executive team. Our study addresses this gap and examines the relationship between an occupational community of top executives and the quality of internal control. We construct a unique measure for the executive occupational community based on CEO and CFO’s joint tenure. Our findings show that the number of years of CEO/CFO’s joint tenure is significantly and negatively associated with internal control weakness, suggesting that the longer the executive relationship, the lower the likelihood of internal control weakness. Our study indicates that the presence of an occupational community contributes to better internal control.
