Supply chain coordination with information design

We consider the coordination of a supplier–retailer supply chain where, in addition to classical contract considerations, a supplier decides the adoption of an information structure (IS) for the supply chain, with a higher-quality IS allowing the supply chain parties to obtain a more accurate demand forecast. Because a wholesale price contract cannot coordinate the supply chain due to misaligned incentives of supply chain parties, we explore what common coordinating contracts in the classical coordination literature can continue coordinating the supply chain with the IS adoption. Interestingly, our analysis appears to reveal the power of simplicity: some simple classical coordinating contracts (e.g., the buy-back and revenue-sharing contracts), though not designed with the IS consideration, still coordinate the supply chain, whereas other more complicated classical contracts (e.g., the quantity flexibility and sales rebate contracts) fail to do so. We derive a general condition for supply chain coordination and show that any contract with a newsvendor-like transfer payment can coordinate the supply chain.     

Pathological Gambling and Motor Impulsivity: A Systematic Review with Meta-Analysis

Motor impulsivity, which is an impairment in withholding and cancelling inappropriate responses, may account for the inability for pathological gamblers (PGs) to inhibit their urges to gamble. The aim of this systematic review was to perform a quantitative and qualitative synthesis of existing studies in order to assess whether PGs without comorbid substance use disorder have elevated motor impulsivity, relative to healthy controls. An exhaustive literature search led to the identification of 20 studies which met inclusion criteria. A meta-analysis was then conducted on the following measures: stop signal reaction time from the stop signal task; commission errors, omission errors, and Go reaction time from the Go/No-Go task; and the motor impulsiveness subscale of the Barratt Impulsiveness Scale (BIS-Motor). The results revealed a moderate to large mean effect size of stop signal reaction time, small to moderate mean effect sizes for commission errors, omission errors and Go reaction time, and a large mean effect size for the BIS-Motor. Significant heterogeneity in effect sizes was observed on most behavioural measures, but not for the BIS-Motor or omission errors on the Go/No-Go task. Overall, these results suggest that motor impulsivity may be one of the features of PG psychopathology, accounting for their poor inhibitory control over gambling behaviours. Moreover, other deficits in sustained attention, or more generally in executive/cognitive control, may be present in PGs. We discuss the implications, limitations of existing research, and suggested avenues for future studies, particularly the need to acknowledge heterogeneity amongst PGs and amongst different behavioural measures.     

Relationship satisfaction in lesbian couples: Review,methodological critique,and research agenda

ABSTRACT

There has been increased interest in and attention to understanding the characteristics associated with relationship satisfaction among same-sex couples. This review examines the individual, couple, and external factors associated with relationship satisfaction among contemporary lesbian couples, highlighting domains such as internalized homophobia, personality, communication, conflict, sex, stress, and social support. I discuss methodological concerns and future directions to advance research in this area.     

La revolución digital: mobile media use in contemporary Cuba

ABSTRACT

Recent scholarship on mobile internet use in the Global South highlights access disparities, along with shifting social practices that accompany greater web connectivity. Cuba is part of the Global South, and ranks among the least internet connected countries in the world. Venegas’[2010. Digital dilemmas: The state, the individual, and digital media in Cuba. New Brunswick, NJ: Rutgers University Press] thorough account of technology use in Cuba positions Cuban digital media as an assemblage of political, economic, historical, and global factors. Recently, however, mobile digital technologies in Cuba have undergone rapid transformation. Continuing tensions between the US and Cuba remain part of how the country's infrastructure and internet practices develop in location-specific ways. In this paper, we utilize ethnographically-informed data to provide a case study of the mobile internet adaptations in Havana, Cuba. Specifically, we draw upon Sutko and de Souza e Silva [2010. Location-aware mobile media and urban sociability. New Media & Society, 13(5), 807–823] framework for location-aware mobile media and urban sociability to examine the unique communication and coordination practices of Havana internet culture. Additionally, Massey [2005. For space. London: Sage] and Wiley and Packer [2010. Rethinking communication after the mobilities turn. The Communication Review, 13(4), 263–268] notions of space allow investigation of Cuban cultural technologies within a larger social field. These theoretical lenses enable interrogation of mobile device adaptations on mobility, sociability, and space to position Cuban media use as an assemblage of local and global forces.     

产业创新网络动态演进机制模拟与实例分析

产业创新网络是由产业内以创新为目的、相互独立又相互关联的企业以及企业间关系耦合而成的网络.产业创新网络的演进机制是其研究的关键内容,但这一领域的研究成果、特别是定量研究成果较少.文章基于社会网络理论,将产业创新网络描述为企业间以创新为目的的关系网络;企业节点及其相互关系构成产业创新网络结构,知识资本和社会资本是产业网络创新的基础,企业的进入与退出机制以及企业的行为决策影响产业创新网络的演进过程,基于此构建基于多智能体的仿真模型来分析产业创新网络的演进机制;中国基于TD-SCDMA标准的3G产业网络演进过程实例表明,该仿真模型能够有效反映产业创新网络演进的特点,仿真模拟是分析产业创新网络演进机制的有效方法.     

Different,Like Everyone Else: Stuff White People Like and the Marketplace of Diversity

This article explores Stuff White People Like (SWPL), a popular blog that has lampooned the cultural practices of a certain kind of bourgeoisie‐bohemian White person since its inception in early 2008. The overwhelmingly positive reception of the blog motivated the authors to explore the complexities of this commercial humor project in the context of the twenty‐first century multicultural neoliberalism in the United States. Through analysis of both the blog entries and online audience response, they ultimately claim that SWPL is limited in its potential for antiracist cultural work because it fails to challenge the logic of neoliberalism—indeed, it operates firmly within it—and defers a radical critique of White privilege. Moreover, SWPL facilitates gleeful celebration of essentialized White idiosyncrasies by incorporating a form of White “ethnicity” in the twenty‐first century neoliberal marketplace of diversity.
