基于卷筒纸胶印的印品在线缺陷检测系统

本文详细介绍了一种视觉系统,该系统可以实现对卷筒纸胶印过程中产生的印品缺陷进行检测和定位。具体来说,该系统能够对高速卷筒纸印刷进行实时监控,并且可在印刷过程中出现任何影响印品质量的故障（如结构缺陷、色彩偏差、漏字、墨点、墨杠等）时向操作人员发出警报。本文还介绍了机器视觉系统的硬件部分和用于彩色图像扫描及印品缺陷检测定位的图像处理算法。从本质上讲,该系统采用高速扫描算法检测图像的边缘和边界,利用线性和非线性的滤波器对动态大小、阈值和转换信息做进一步的分析。除了在实验室内进行实验以外,还建立了系统模型,系统模型可应用在卷筒纸印刷中,在真实条件下对模型的功能进行评价。将该系统安装在凹印机上进行实验,结果表明该机器视觉系统同样可以成功地对缺陷进行监控和检测。     

Trends in injury-related deaths before and after dissolution of the Union of Soviet Socialist Republics

The relationship of death rates due to injury with the dissolution of the Soviet empire deserves special focus because of the impact of injury deaths on the productive working population between the ages of 15 and 65 years. A retrospective review was performed of annual mortality rates due to intentional and unintentional injuries, using WHO data from 1980 to 2003. Using data from a comparison group in Western Europe, the nations of the former Union of Soviet Socialist Republics (USSR) were studied. Annual death rates were examined using polynomial regression after 3-year moving averages smoothed the plots. The majority of trends in injury-related death noted in the comparison group decreased constantly over time. In contrast, many nations of the former USSR experienced an initial decrease, reaching a nadir in 1985 - 1987, followed by an increase in injury-related deaths. Moreover, many of these nations experienced a subsequent decrease following the dissolution of the USSR in 1991. The monitoring of trends in injury mortality in countries experiencing social and political upheavals is warranted.     

Efficient replenishment in the distribution channel

Efficient replenishment (ER), a business process that involves the reduction of order cost to facilitate deliveries of goods from the manufacturer to the retailer, is becoming increasingly important in distribution channel management. While a well-executed ER program is expected to lower total channel costs and increase channel profit, very little is known about how this incremental channel profit is distributed between the manufacturer and the retailer and how it varies across the two common channel relationship structures, retailer price leadership and manufacturer price leadership.In this paper, we develop the conditions under which the manufacturer and the retailer gain more or less from the adoption of ER based on a game theoretic channel model of bilateral monopoly under the two channel relationship structures. We develop analytic results on the impact of ER on purchase quantity, price and the distribution of profits in three cases, namely, (1) when only the retailer adopts ER, (2) when both the manufacturer and the retailer adopt ER, and (3) when the manufacturer and the retailer are vertically integrated in the distribution channel, which adopts ER.The results, which can be generalized for all demand functions, show that the manufacturer benefits from the retailer's adoption of ER only when the manufacturer's holding cost relative to the retailer's is sufficiently large, relative to its order cost relative to the retailer's. By adopting ER, the retailer gains more than what the manufacturer gains even if the manufacturer is the price leader. Both the parties are likely to gain more if they both adopt ER than if only the retailer adopts ER. The incremental channel profit due to the retailer's ER adoption is highest in a vertically integrated distribution channel and is greater in a retailer-led channel relationship than in a manufacturer-led relationship.     

Exploring factors influencing US millennial consumers’ use of tap-and-go payment technology

ABSTRACT

Although mobile payment (MP) represents a possibility for traditional brick-and-mortar US retailers to enhance the quality of customer service, mobile payment adoption in the US has lagged, with research regarding this phenomenon in the US seemingly in its embryonic stage. The current study contributes to the literature on mobile payment adoption in the US by investigating the factors on US millennial consumers’ use of mobile payment technology, operationalized in the study as tap-and-go payment systems. The study mirrors a study of the acceptance of mobile shopping technology among German consumers, with some extension. The study incorporated mobile payment risk perception, system trust, and socio-cultural influence into an extended technology acceptance model (TAM) to explore this issue. Results from a survey conducted among 357 US Millennials indicate that perceived ease of use of MP (PEOUMP); perceived usefulness (PUMP); and risk perception all influence attitude toward mobile payment (AttMP). System trust, socio-cultural influence, and AttMP all influence MP use intention. The paper discussed the limitations of the study and future research directions.     

Footwear with feeling: a cultural approach to product development

ABSTRACT

Holt (2004) pioneered a change in marketing discourse by outlining how brands can become icons through tapping into cultural mythologies of the time. Yet, the theory has remained purely focused on branded consumption. This film extends the approach to the realm of product development and focuses on the transformation of a fashion trend into a consistent product category by examining the flatform shoe, a new shoe style that blends the height of a heel with the comfort of a flat. Through qualitative interviews and ethnographic analysis, this film argues that consumers are able to attach a strong postfeminist sensibility to the style. This helps to elevate the style to a mainstream category of its own through an adherence to cultural branding principles.     

The Uruguay Round: Expectations of developing countries

The recovery of world trade in the last few years has not led to an improvement in the situation of the developing countries. Many commodity prices are currently at their lowest level since the 1930s, and protectionism is on the increase. Are the Uruguay Round negotiations likely to bring positive results for the developing countries?     

Do managers use earnings guidance to influence street earnings exclusions?

Despite the apparent importance of “street earnings” to investors, we know relatively little about the process through which this earnings metric is determined. The limited evidence in the extant literature provides analyst-centric explanations, suggesting that analysts’ abilities and incentives influence which line items forecast-tracking services exclude from GAAP earnings to arrive at street earnings. We propose an alternative explanation: managers actively influence analysts’ forecast exclusion decisions via earnings guidance. We test this explanation by examining how earnings guidance influences two aspects of analysts’ exclusions: (1) special item exclusions (i.e., nonrecurring items) and (2) incremental exclusions (i.e., recurring items). We find that for firms with no special items in the previous year, when managers guide, analysts exclude almost all current-year special items, whereas when managers do not guide, the proportion that analysts exclude is significantly lower. More importantly, we that analysts’ incremental exclusions are significantly higher when managers guide than when they do not guide. Overall, our evidence suggests that managers play an active role in influencing the composition of street earnings via earnings guidance.     

1974: World population year

In December 1970, the General Assembly of the United Nations designated 1974 as World Population Year. Herewith, the Assembly was giving recognition to the growing involvement of the United Nations System in the population field and to the need for focussing international attention on different demographic aspects.     

Supply chain agility: review,classification and synthesis

Supply chain agility (SCA) has emerged as an important capability to remain competitive in this era of business uncertainty and turbulence. This study aims to gain knowledge of the current state of research on SCA, specifically to have conceptual clarity and synthesise future research avenues. To achieve these goals, we have carried out a systematic review of 118 research papers on SCA published from 1999 to 2016. The findings suggest that the domain has witnessed steady growth since its inception, but little consensus has been observed around its definition and boundaries. To counter these definitional ambiguities, we have presented a comprehensive definition of SCA. The paper further discusses SCA along three thematic categories: the first considers SCA from the strategic perspective, the second considers SCA as a capability and focuses on its enablers and the third explores the impact of SCA on performance. Finally, towards the conclusion, a holistic framework summarising the findings is presented.
