Overcoming the Trend Toward Healthier Foods: The Impact of Advertising and Intangibles on Investor Returns in the Packaged Food Industry

The study analyzes the impact of advertising, goodwill, and other intangibles on investor returns in the consumer packaged food and beverage industry during 2008–2012, a timeframe during which smaller brands wrestled $18 billion in sales away from large manufacturers of processed foods. The findings demonstrate that those firms that were able to allocate a greater percentage of their revenue to their ongoing advertising efforts were able to enhance investor holding period returns (HPR). In addition, those firms with a higher ratio of intangible assets other than goodwill to total assets were also able to enhance HPR. However, there was not a significant positive relationship between the ratio of acquired goodwill to total assets and HPR. Hence, packaged food and beverage manufacturers are advised to seek competitive advantages through their own brand-building efforts rather than seeking to enhance investor returns through a strategy based on company mergers and acquisitions.

完善产品检验模式 有效控制产品质量

技术引进以来,江钻股份公司对产品制造质量的检验基本上采用的是专职检验人员把关的形式。但随着近年来企业产量的增加以及多品种、小批量、短周期等制造特点的日趋突现,目前的检验方式已不能完全满足制造企业的要求。为此,2007年江钻股份公司对这种把关式的质量检验模式进行了创新改善,确立了一个既能保证产品质量又能满足目前生产和质量控制要求的新的检验模式。创新的质量检验模式带动了公司的各项管理工作,优化了质量管理结构,提高了工作效率,促进了公司快速应对市场的能力。     

定位精度的一种测试补偿方法

定位精度是机床的基本精度之一。文章阐述了利用高精度的激光干涉仪测试机床在装配过程中的定位精度,并把定位误差补入数控系统,可以有效地提高机床的精度,使定位精度达5 m。在确定机床定位精度的过程中,对温度条件在一定程度上对定位精度的影响不能忽略,可以通过激光干涉仪测试定位精度并补入数控系统,补偿后的机床定位精度可以达到6μm。

Exact linear rank tests for two‐sample equivalence problems with continuous data

The present paper introduces a methodology for the semiparametric or non‐parametric two‐sample equivalence problem when the effects are specified by statistical functionals. The mean relative risk functional of two populations is given by the average of the time‐dependent risk. This functional is a meaningful non‐parametric quantity, which is invariant under strictly monotone transformations of the data. In the case of proportional hazard models, the functional determines just the proportional hazard risk factor. It is shown that an equivalence test of the type of the two‐sample Savage rank test is appropriate for this functional. Under proportional hazards, this test can be carried out as an exact level α test. It also works quite well under other semiparametric models. Similar results are presented for a Wilcoxon rank‐sum test for equivalence based on the Mann–Whitney functional given by the relative treatment effect.

Am I intruding? Developing a conceptualisation of advertising intrusiveness

This study develops a conceptual framework of advertising intrusiveness that extends previous research on the topic by examining both drivers and consequences. To achieve this, the work draws on in-depth interviews with 29 adult consumers who report experiencing intrusive advertising in their daily lives. Three drivers of advertising intrusiveness are identified – temporal disruption, visual disruption and flow disruption – along with three consequences – emotional response, behavioural response and cognitive response. From these drivers and consequences, a conceptual framework of advertising intrusiveness is developed based on ideas about psychological reactance. Based on this framework it is proposed that, while all advertisements might ultimately be perceived as intrusive, an advertisement’s characteristics, which are the identified subcomponents of the drivers of intrusiveness, exacerbate the resultant consequences.
