In this paper we present and discuss several optimisation problems that arise in the management of data flow in wireless sensor
networks (WSNets). We consider a hierarchical architecture for WSNets composed of sensors, relays, and relay gateways. Sensors
send data they generate at a known average bit rate to relays in one hop. The relay nodes use a multi-hop mechanism to reach
a set of assigned gateways which then forward the data directly to the base station. We are concerned with finding an assignment
of relay gateways to relays so that certain constraints are satisfied. We define a unified model in which constraints such
as lifetime, data delay, and data flow splitting are formulated in terms of four optimisation problem in graphs. 相似文献

A gender divide in gambling is commonly observed among college populations. This study examines whether settings where students gamble on poker mediate the relationship between gender and poker gambling behaviours. Undergraduate poker players, 126 females and 242 males, were randomly sampled from three universities in Montreal, Canada. Three outcomes measuring risky behaviours were considered: severity of gambling problems as measured by the Problem Gambling Severity Index (PGSI), past-year poker spending and past-year poker debt. Multiple mediation analyses were conducted. The effect of gender on outcomes was analysed through three putative mediators: gambling on poker in private residences, in public locations or on the Internet. Male gender positively relates to risky gambling behaviours and occurrence of gambling in various settings. Risky gambling behaviours are positively related to gambling in various settings. Overall, the occurrence of playing poker in public locations and on the Internet emerged as significant mediators in relation to PGSI score, past-year poker spending and past-year poker debt. Given the nature of the processes by which gender is related to risky gambling behaviours among undergraduate students, gambling needs to be understood through a perspective that focuses as much on contexts as it does on individuals. 相似文献

Intercultural coaching takes place in the highly complex reality of a globalized world. The coachee is an individual acting in the situational context of his assignment and his corporate culture. He has been socialized in his own culture, but is communicating and interacting with people who have been socialized in different cultures. In order to identify and solve problems, all three aspects (person, situation, culture) have to be considered. Some aspects may have more influence than others may, but they combine in a closely interwoven system. The authors outline the theoretical background of intercultural coaching and illustrate the process with case studies. 相似文献

Summary. Data in the social, behavioural and health sciences frequently come from observational studies instead of controlled experiments. In addition to random errors, observational data typically contain additional sources of uncertainty such as missing values, unmeasured confounders and selection biases. Also, the research question is often different from that which a particular source of data was designed to answer, and so not all relevant variables are measured. As a result, multiple sources of data are often necessary to identify the biases and to inform about different aspects of the research question. Bayesian graphical models provide a coherent way to connect a series of local submodels, based on different data sets, into a global unified analysis. We present a unified modelling framework that will account for multiple biases simultaneously and give more accurate parameter estimates than standard approaches. We illustrate our approach by analysing data from a study of water disinfection by-products and adverse birth outcomes in the UK. 相似文献

While some scholars contend that immigrant integration is predicated on a strategic distancing from Blacks and closeness to Whites, others argue that highly racialised immigrants share more commonality with Black Americans than Whites. Drawing on in-depth interviews with Mexican immigrant newcomers to Los Angeles, California, this article examines how immigrants make sense of their position in U.S. socioracial hierarchy vis-à-vis other racialised groups. I show that as immigrants navigate U.S. social, racial, and political landscapes, they come to view ‘American-ness’ and the citizenship status inherent in it as a key marker of distinction between themselves and those they deem ‘American’. Immigrants thus view their group status as an inferior one relative not only to the dominant White group, but also to Black Americans, albeit for qualitatively different reasons. Findings highlight how the vulnerability of ‘illegality’ not only reinforces existing social boundaries with Whites, but also shapes the nature of socioracial boundaries with Black Americans that can hinder the potential for racial solidarity and has broader implications for the U.S. socioracial hierarchy. 相似文献

Lotteries are one of the most prevalent forms of gambling and generate substantial state revenues. They are also argued to be one of the least harmful forms of gambling. This paper is one of the first to examine exclusive lottery gamblers and compares their gambling patterns and problems as well other associated risky behaviours to those who are not exclusive lottery gamblers. Data were derived from two large surveys conducted with representative adult samples in France (n?=?15,635) and Québec (n?=?23,896). Participants were separated into two groups: exclusive lottery gamblers (ELGs) and non-exclusive lottery gamblers. Using multivariate analysis, study results reveal that ELGs, who represent two thirds of gamblers, generally exhibit less intensive gambling patterns and are less likely to report other risky behaviours. However, harms associated with moderate risk and problem gambling are found to be concentrated in specific subpopulations for both groups, primarily males, older individuals, and those who report lower income and education level. Given widespread participation in lotteries and concentration of harm within specific subgroups, these findings point to the need for prevention efforts despite the lower levels of harm associated with lottery gambling. 相似文献

The grief of Chinese mothers is examined in a phenomenological exploratory study. Grieving for the deceased child is moderated by diverse Chinese religious beliefs intertwined with cultural practices. Five aspects of grieving include giving meaning to the child’s life and death, quality and assurance of the afterlife, the function of crying, and a continuing bond. Extrapolating from the mothers’ grieving are questions related to the implications of children’s death for other family members and the significance of the interconnectedness of the self, others, the environment and the universe in processing a crisis through religion and spirituality in multicultural social work. 相似文献
