Factors Affecting Alcohol Purchase Decisions and Expenditures: A Sample Selection Analysis by Ethnicity in Malaysia

Heckman’s sample selection model was applied to data from the Malaysian Household Expenditure Survey 2004/2005 to examine the factors influencing the likelihood of purchasing and the amount spent on alcohol in Malaysia. Results of the marginal effects suggest that while socio-demographic factors are important determinants of household purchase decisions and expenditure levels on alcohol in Malaysia, the effects vary across ethnic groups. Specifically, although education had a significant but modest impact in reducing the probability of alcohol purchases and expenditure levels among ethnic Chinese households, this effect was not evident among the ethnic Indians and other races. While increasing household size lowered the likelihood of purchasing alcohol and its expenditure levels for all ethnic groups, the reinforcing effects of both income and gender were relevant only for ethnic Chinese and Indian households. Last, urban Indian households were less likely to purchase alcohol and spend less compared to rural Indian households.

How rival partners compete based on cooperation?

Prior studies of coopetition have explained the what, how and why of firms cooperating with competitors. Among these, examining the how question as to the stream of coopetition dynamics is the most challenging theme. Previous research has focused much more on the cooperation side. Less attention has been paid to the competition side to reveal what happens to competition after the competitors have collaborated. This study sheds light on the issue of cooperation-based competition by answering the question: while cooperating with competitors, how do rival partners compete based on cooperation? Linking the competitive dynamics perspective to coopetition, we conducted a single-case study to analyse the competition between two leading competitors in the Taiwanese bicycle industry. We collected the reported issues pertaining to the competition in the European market and supported by in-depth interviews. The analysis leads us to develop three propositions and a conceptual framework for illustrating the cooperation-based competition and addressing how cooperation may influence competition in a coopetition relationship. This study provides new insights into a theoretical issue of cooperation-based competition. The case also provides management implications while taking a coopetition strategy.

An mHealth Approach to Extend a Brief Intervention for Adolescent Alcohol Use and Suicidal Behavior: Qualitative Analyses of Adolescent and Parent Feedback

Abstract

Mobile health (mHealth) tools that supplement inpatient psychiatric care can maintain and enhance intervention effects following hospitalization. Adolescents hospitalized following a suicidal event represent a vulnerable population who could greatly benefit from such an mHealth intervention. In specific, suicidal adolescents who drink alcohol are in need of robust interventions that address the bidirectional relationship between alcohol use and suicidal thoughts and behaviors, because it puts them at especially high risk for suicide upon discharge. The purpose of this study was to conduct qualitative interviews to gather feedback to improve a brief alcohol intervention provided to suicidal adolescents during psychiatric hospitalization, and to develop a mHealth tool to extend care after discharge. Participants, eight adolescents and their parents, identified the need for a smartphone application to deliver intervention content to adolescents and parents during the posthospitalization period. Adolescents sought support in meeting alcohol- and mood-related goals, while parents desired general resources as well as tips for conversations with their adolescent about mood and alcohol use.     

Quick Response under Competition

We consider a manufacturer serving two competing retailers that sell their products over a single selling season. The retailers place their regular orders before the season starts. In addition to this initial order, quick response (QR) provides a retailer with an additional replenishment opportunity after demand uncertainty is resolved. The manufacturer determines the unit price for QR replenishment. We characterize the retailers’ ordering, and the manufacturer's pricing decisions in equilibrium when none, only one, and both of the retailers have QR ability. We study how the profitability of the manufacturer, the retailers, and the channel depend on QR and competition. We find it may be optimal for the manufacturer to offer QR to only one of the ex ante identical retailers when demand variability is sufficiently, but not overly high. The manufacturer may also find it optimal to offer QR to both or none of the retailers, depending on demand variability. Finally, while QR ability is always attractive for a retailer when competition is ignored, we find QR may prove detrimental when its impact on competition is taken into account.     

Regrounding the ‘Ungrounded Empires’:localization as the geographical catalyst for transnationalism

The emerging literature on transnationalism has reshaped the study of immigration in the USA from ‘melting pot’ and later ‘salad bowl’, to ‘switching board’, which emphasizes the ability of migrants to forge and maintain ties to their home countries. Often under the heading of ‘transnationalism from below’, these studies highlight an alternative form of globalization, in which migrants act as active agents to initiate and structure global interactions. The role of geography, and in particular, localization in transnational spaces, is central to the transnationalism debate, but is yet to be well articulated. While it has been commonly claimed that transnationalism represents deterritorialized practices and organizations, we argue that it is in fact rooted in the territorial division of labour and local community networks in immigrant sending and receiving countries. We examine closely two business sectors engaged in by the Chinese immigrants in Los Angeles: high‐tech firms and accounting firms. Each illustrates, respectively, the close ties of Chinese transnational activities with the economic base of the Los Angeles region, and the contribution of local‐based, low‐wage, small ethnic businesses to the transnational practices. We conclude that deeper localization is the geographical catalyst for transnational networks and practices.     

Vertical Integration under Competition: Forward,Backward, or No Integration?

We consider two competing supply chains, each consisting of supplier, a manufacturer, and a retailer. The suppliers exert effort to improve product quality, and the retailers sell products competitively. Each manufacturer chooses one of the three strategies: forward integration, backward integration, or no vertical integration. We seek for a subgame perfect Nash equilibrium and study the resulting market structure. Moreover, we characterize the effect of vertical integration on profitability, product price, and quality in a competitive setting. Existing literature has shown that, when manufacturers consider only forward integration, they may choose not to vertically integrate in equilibrium. In contrast, we find that, when both forward and backward integration options are considered, disintegration cannot be an equilibrium outcome. In this case, both manufacturers either forward or backward integrate, and the degree of product perishability, cost of quality, and how much consumers value quality are critical for the chosen direction of integration. Furthermore, competition increases attractiveness of backward integration relative to forward integration. We show that, while integrating backward unilaterally is always beneficial, unilateral forward integration can harm a manufacturer's profitability. Finally, vertical integration can result in a better quality product sold at a lower price.     

Multiple dependent state repetitive sampling plans based on one-sided process capability indices

In this research, multiple dependent state and repetitive group sampling are used to design a variable sampling plan based on one-sided process capability indices, which consider the quality of the current lot as well as the quality of the preceding lots. The sample size and critical values of the proposed plan are determined by minimizing the average sample number while satisfying the producer's risk and consumer's risk at corresponding quality levels. In addition, comparisons are made with the existing sampling plans [Pearn and Wu (2006a Pearn, W. L., and C. W. Wu. 2006a. Critical acceptance values and sample sizes of a variables sampling plan for very low fraction of defectives. Omega: International Journal of Management Science 34 (1):90–101.[Crossref], [Web of Science ®] , [Google Scholar]), Yen et al. (2015 Yen, C. H., C. H. Chang, and M. Aslam. 2015. Repetitive variable acceptance sampling plan for one-sided specification. Journal of Statistical Computation and Simulation 85 (6):1102–16.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar])] in terms of average sample number and operating characteristic curve. Finally, an example is provided to illustrate the proposed plan.     

An Exploratory Study of “Parasites” in Taiwan

Deriving from Parasite Single proposed by Yamada (1997), parasites in this study is redefined as those who live with and financially rely on their parents in terms of living expenses after school graduation. The current study adopts the logit model and utilizes the data from the 1999 to 2000 Taiwan Panel Study of Family Dynamics to investigate the determinants of parasites. The finding reveals that gender, age, marital status, and the value of filial piety are significantly different between parasites and non-parasites. Moreover, gender, monthly income, age and marital status are determinants of the probability of being parasites.     

Debt,precarity and gender: male and female temporary labour migrants in Singapore

As one of Asia’s key hubs for transient workers, Singapore’s migration regime creates particularly gendered streams of labour, especially among lower skilled occupations, as is apparent in two key sectors – domestic work and construction work. Drawing on surveys with Bangladeshi construction workers and Indonesian domestic workers based in Singapore, as well as in-depth interviews with each group, this paper examines gendered issues of temporary labour migration, precarity and risk, as they occur against a backdrop of migrant indebtedness. In this paper, we argue that migrant indebtedness occurs along a spectrum that ranges from less visible, or what we call ‘silently’ incurred forms of debt, through to more ‘resonant’ types of debt that are acquired upfront and thus more readily quantifiable. Using this spectrum of migrant indebtedness, we aim to complicate debates about debt-financed migration by underscoring the ways in which notions of debt and unfreedom can be imbricated with both constraints and opportunities for migrants’ agency.
