Community Size,Individual Social Position,and Community Attachment1

Abstract The objective of this investigation is to elaborate and test the linear development and systemic models of community attachment. We focus on the interplay of community size, five social position variables, and three dimensions of community attachment, namely, involvement, amity, and sentiment. Data are obtained from a statewide migration telephone survey of 851 respondents aged 18 and over, conducted in Utah in October 1988. We focus on a weighted subsample of 415 nonmetropolitan respondents. Multiple Classification Analysis (MCA) techniques are employed. Contrary to the linear development model, community size did not have an independent inverse impact on community involvement, amity, and sentiment. Results do vary by social position and community attachment dimensions.     

Culture: A key to management communication between the Asian-Pacific area and Europe

Western culture, and therefore Western management methods and thinking, has devalued other cultures, and it has been assumed that the high culture of dominant nations has taken over. But this is not so; cultures of everyday life are complex and not easily destroyed. They are also systems in motion, that can adapt easily.Tzöl Zae Chung explains the striking differences between Asian and European thinking and ways of managing and doing business. Misunderstandings can occur if two cultures meet without adequate prior preparation. But increasingly, Japanese management methods are revitalizing Asian values and attracting attention. The cultural factor in globalization — especially in the ‘triad’ of trade between the US, the Asian-Pacific region and Europe is becoming critically important.     

A Probabilistic Transmission Model to Assess Infection Risk from Mycobacterium Tuberculosis in Commercial Passenger Trains

The objective of this article is to characterize the risk of infection from airborne Mycobacterium tuberculosis bacilli exposure in commercial passenger trains based on a risk‐based probabilistic transmission modeling. We investigated the tuberculosis (TB) infection risks among commercial passengers by inhaled aerosol M. tuberculosis bacilli and quantify the patterns of TB transmission in Taiwan High Speed Rail (THSR). A deterministic Wells‐Riley mathematical model was used to account for the probability of infection risk from M. tuberculosis bacilli by linking the cough‐generated aerosol M. tuberculosis bacilli concentration and particle size distribution. We found that (i) the quantum generation rate of TB was estimated with a lognormal distribution of geometric mean (GM) of 54.29 and geometric standard deviation (GSD) of 3.05 quantum/h at particle size ≤ 5 μm and (ii) the basic reproduction numbers (R₀) were estimated to be 0.69 (0.06–6.79), 2.82 (0.32–20.97), and 2.31 (0.25–17.69) for business, standard, and nonreserved cabins, respectively. The results indicate that commercial passengers taking standard and nonreserved cabins had higher transmission risk than those in business cabins based on conservatism. Our results also reveal that even a brief exposure, as in the bronchoscopy cases, can also result in a transmission when the quantum generation rate is high. This study could contribute to a better understanding of the dynamics of TB transmission in commercial passenger trains by assessing the relationship between TB infectiousness, passenger mobility, and key model parameters such as seat occupancy, ventilation rate, and exposure duration.     

Subethnic interpersonal dynamic in diasporic community: a study on Chinese immigrants in Vancouver

ABSTRACT

Ethnicity is a social construct that can be conceptualised as a social classification delineating certain boundaries between an ethnic group and the dominant group. Members of an ethnic group are assumed to share similar cultural characteristics and to be homogenous among themselves. Many studies in ethnic organisations have indicated that subethnicity also exists within an ethnic group, but research on subethnicity is scant. Based on the findings of an exploratory study conducted in Vancouver, Canada, we examined how, at an interpersonal level, place of origin, language, mutual bias and discrimination and transnational politics divide the Chinese diasporic community subethnically. Meanwhile, being Chinese in the Canadian context and willingness to break the subethnic boundaries are noted as counterforces to the subethnic divide. We contend that interpersonal interaction is an imperative dimension for the understanding of the shaping of boundary between different subethnic groups.     

Online interval scheduling: randomized and multiprocessor cases

We consider the problem of scheduling a set of equal-length intervals arriving online, where each interval is associated with a weight and the objective is to maximize the total weight of completed intervals. An optimal 4-competitive algorithm has long been known in the deterministic case, but the randomized case remains open. We give the first randomized algorithm for this problem, achieving a competitive ratio of 3.5822. We also prove a randomized lower bound of 4/3, which is an improvement over the previous 5/4 result. Then we show that the techniques can be carried to the deterministic multiprocessor case, giving a 3.5822-competitive 2-processor algorithm, and a 4/3 lower bound for any number of processors. We also give a lower bound of 2 for the case of two processors. A preliminary version of this paper appeared in the Proceedings of COCOON 2007, LNCS, vol. 4598, pp. 176–186.

Linguistic Markers of Psychological State through Media Interviews: John Kerry and John Edwards in 2004, Al Gore in 2000

What can we learn about presidential candidates by examining their speech in natural conversation? In the present study, the television interviews from the 2004 Democratic presidential primary campaign of John Kerry ( N = 29) and John Edwards ( N = 34) were examined using linguistic analyses. Results indicate that Kerry and Edwards were similar in their use of positive emotion words, but that Kerry used significantly higher rates of negative emotion words than did Edwards. Comparisons with televised interviews of Al Gore from the 2000 presidential campaign ( N = 17) revealed striking similarities in the linguistic styles of Gore and Kerry. Gore's linguistic style overlapped considerably with that of Kerry on pronoun usage and many cognitive domains. This study points to how linguistic analyses can give us a clearer picture of how political candidates think, act, and feel.     

Single‐Period Two‐Product Assemble‐to‐Order Systems with a Common Component and Uncertain Demand Patterns

We consider a single‐period assemble‐to‐order system that produces two types of end products to satisfy two independent and stochastic customer orders. Each type of product is used to fulfill a particular customer order and these two products share a common component. Furthermore, one customer may confirm her order before the other one, and the manufacturer needs to make a commitment immediately upon the receipt of each customer order on how many products to be delivered. We propose a model for optimizing the inventory and production decisions under the above ATO environment. We also extend our model to the situation where the manufacturer can fulfill the unsatisfied low‐priority demand using the left‐over inventories after fulfilling the high‐priority demand, in case the low‐priority customer arrives first. Numerical experiments are conducted, which provide some interesting insights on the impact of uncertain demand pattern.     

Approximation Algorithms in Batch Processing

A polynomial approximation scheme for minimizing makespan in a batch processing system under dynamic job arrivals is presented. A lower bound of on the competitive ratio of any on-line algorithm is proved. This is matched by an on-line algorithm for the special case of unbounded machine capacity.     

Bayesian estimation for the exponentiated Weibull model under Type II progressive censoring

Based on progressive Type II censored samples, we have derived the maximum likelihood and Bayes estimators for the two shape parameters and the reliability function of the exponentiated Weibull lifetime model. We obtained Bayes estimators using both the symmetric and asymmetric loss functions via squared error loss and linex loss functions. This was done with respect to the conjugate priors for two shape parameters. We used an approximation based on the Lindley (Trabajos de Stadistca 21, 223–237, 1980) method for obtaining Bayes estimates under these loss functions. We made comparisons between these estimators and the maximum likelihood estimators using a Monte Carlo simulation study.     

Ownership Strategy and Foreign Affiliate Performance in Multinational Family Business Groups: A Double-edged Sword

We argue that ownership strategies can be a double edged sword for multinational family business groups from emerging economies and the performance of their affiliates located abroad. We test an integrated framework based on internalization and agency theory on a longitudinal dataset of multinational family business groups from Taiwan. We find evidence for the contingent impact of cultural differences and family management on the association between ownership strategy and affiliate performance. While direct ownership is seen as offering more control over the affiliate, we show that this comes at a performance cost for affiliates in culturally different host countries and affiliates under family management. Indirect ownership seems to be one way to positively influence affiliate performance in culturally distant countries, but seems not to be contingent on family management utilization.
