Agent‐Based Modeling to Simulate Contamination Events and Evaluate Threat Management Strategies in Water Distribution Systems

In the event of contamination of a water distribution system, decisions must be made to mitigate the impact of the contamination and to protect public health. Making threat management decisions while a contaminant spreads through the network is a dynamic and interactive process. Response actions taken by the utility managers and water consumption choices made by the consumers will affect the hydraulics, and thus the spread of the contaminant plume, in the network. A modeling framework that allows the simulation of a contamination event under the effects of actions taken by utility managers and consumers will be a useful tool for the analysis of alternative threat mitigation and management strategies. This article presents a multiagent modeling framework that combines agent‐based, mechanistic, and dynamic methods. Agents select actions based on a set of rules that represent an individual's autonomy, goal‐based desires, and reaction to the environment and the actions of other agents. Consumer behaviors including ingestion, mobility, reduction of water demands, and word‐of‐mouth communication are simulated. Management strategies are evaluated, including opening hydrants to flush the contaminant and broadcasts. As actions taken by consumer agents and utility operators affect demands and flows in the system, the mechanistic model is updated. Management strategies are evaluated based on the exposure of the population to the contaminant. The framework is designed to consider the typical issues involved in water distribution threat management and provides valuable analysis of threat containment strategies for water distribution system contamination events.     

Child,Parent, and Situational Correlates of Familial Ethnic/Race Socialization

This study examines child, parent, and situational correlates of familial ethnic/race socialization using nationally representative data gathered as part of the Early Childhood Longitudinal Study, Kindergarten Class of 1998 – 1999 (ECLS‐K). The ECLS‐K sample (N = 18,950) includes White, Black, Hispanic, Asian, Native Hawaiian/Pacific Islander, American Indian, and multiracial kindergarteners, with survey data available at the child, parent/guardian, teacher, and school level. We find that child correlates such as race and gender, parent correlates such as education and warmth of parent‐child relationship, and situational correlates such as percent of minorities at the child’s school and cultural event participation influence how often family members discuss children’s ethnic/racial heritage with them. We advocate for continued research of contextualized family dynamics.     

A Holland Perspective on the U.S. Workforce From 1960 to 2000

The authors analyze civilian occupations and employment data collected by the U.S. Census Bureau in 1960, 1970, 1980, 1990, and 2000 with respect to 6 kinds of work (Holland's RIASEC [Realistic, Investigative, Artistic, Social, Enterprising, Conventional] classification), employment, and gender. For the 1990 and 2000 censuses, kinds of work, gender, and income are analyzed, and for the 2000 census, kinds of work, age, and gender are examined. Past employment trends developed from census data are further analyzed with respect to Bureau of Labor Statistics employment projections through 2012. Implications for further research, employment policy, and career services are offered.     

Locating Gender in Environmental Sociology

Environmental sociology is premised on the inseparability of humans and nature and involves an analytical focus on the place of power and social inequality in shaping human/nonhuman interactions. Our purpose here is to conduct a broad overview of the place of gender in environmental sociology. We review gender‐relevant scholarship within environmental sociology and argue that to date, critical gender theorizing in the sub‐discipline is relatively undeveloped, as evidenced by theory that examines gender without considering power relations. We argue that this represents a shortcoming that should be addressed by future scholarship. In order to inform future critical gender–environment theorizing, we provide a brief review of ecofeminism and note promising examples of scholarship that takes power and inequality seriously when accounting for phenomena of relevance to women and the environment. It is likely that theorizing at the intersection of gender and the environment will become more prevalent given a growing consensus that social justice and equity are precursors to ecological sustainability; environmental sociologists could be the vanguard of critical gender–environment theory.     

From leprosy to The Willow Tree: decoding disability and Islamic spirituality in Iranian film

The lack of attention in academic discourse to representations of disability in films from the Middle East has led to an incomplete picture of representations of disability in global cinema. For instance, the diverse meanings of disability in Iranian cinema and the influence of disability on the emergence of Iranian New Wave cinema have been almost completely ignored by scholars. A number of award-winning films from Iran have featured disability as central to their narratives – such as The House is Black (1963), Taste of Cherry (1997), The Color of Paradise (1999), The Willow Tree (2005), and The Painting Pool (2013). Disability in these films serves alternatively as a symbol of spiritual possibility, a mark of marginalization, and a covert social critique. These films examine the emotional, physical, and social implications of disability, while celebrating the cultural power of film to challenge social, religious, and artistic barriers.     

Self-care among school-aged children of immigrants

The present study uses data from the National Household Education Surveys Program to examine the unsupervised time (“self-care”) experienced by children in immigrant families. We argue that traditional models of self-care are insufficient for understanding self-care among immigrant families and should be expanded to capture the unique characteristics of this population. Considering the high rates of poverty, limited English proficiency, and unique cultural norms of immigrant parents, children of immigrants may be especially at-risk for self-care. Interestingly, results demonstrate that immigrant parents are not more likely to leave their children unsupervised than native-born parents, however the context surrounding self-care appears to differ, as immigrant children are more likely to be caring for a sibling during self-care. Additionally, we find that within immigrant families, boys and children of parents who speak a non-English language at home are more likely to be in self-care. These findings underscore the importance of examining parental nativity status in research on child care arrangements, as patterns and contextual factors associated with self-care may depend on the immigrant status of the parent.     

Commentary on: Why Do Pacific People with Multiple Ethnic Affiliations Have Poorer Subjective Wellbeing? Negative Ingroup Affect Mediates the Identity Tension Effect,Manuela & Sibley, 2012

This commentary is a response to the article described above. While applauding the attention given to the multi-ethnic population, it queries some aspects of the study design and findings. Specifically, I examine the assumptions underpinning the use of a Pacific measure of family wellbeing to evaluate families that are not only Pacific origin, ask some questions regarding the sampling methods and content, and question the inference that because people with Pacific/non-Pacific multi-ethnic affiliations have lower self-esteem, mediated by less warmth towards Pacific peoples, that this necessarily reflects the internalisation of negative beliefs espoused by the dominant Pakeha (white) ethnic group. Alternative possible explanations for this are explored.     

Key questions in considering guided practice for vulnerable Australian children

Anna Yeatman and Joanna Penglase (August 2004) provide a useful review of the literature on ‘Looking After Children’ (LAC), a guided practice system for children living in out‐of‐home care. In summarising the polarised debate, the authors point to an unresolved situation in which advocates have uncritically adopted individualised care planning, as a way of improving outcomes in child welfare while critics have not offered alternatives for systemic reform. This is an area of troubled social policy and the debate cannot rest here. This paper suggests a number of pressing research questions to be addressed. The urgency of the issues and the characteristics of local service systems mean LAC needs to be evaluated in the Australian context, taking into account the local experience and participation of children, families and their social workers.     

Hispanic Fertility,Religion and Religiousness in the U.S.

Is the higher fertility of Hispanics in the United States due to their religion and/or to their greater religiousness? Evidence from national survey data indicates no difference in fertility between Protestant and Catholic Hispanic women but Hispanics are more religious than non-Hispanics in terms of the perceived importance of religion in their personal lives. Religiousness is associated with higher fertility but Hispanic fertility is higher than non-Hispanic fertility regardless of religion or religiousness. Ethnic differences in education and income in turn are more important for fertility than the religious dimension.
