Networks embedded in n-dimensional space: The impact of dimensionality change

Social networks can be embedded in an n-dimensional space, where the dimensions may reveal or denote underlying properties of interest. When the pertaining actors occupy niches of resources in this space, e.g., organizational niches of affiliates, we show there exists a non-monotonic effect of dimensionality change. Depending on niche width, relatively narrow or wide, dimensionality change has opposing effects on niche volume.     

Moving targets: determinants of nutritional preferences and habitat use in an urban ant community

Urban environments are often associated with reduced biodiversity, presumably because they are typically more fragmented, warmer, and drier than nearby non-urban environments. However, urban landscapes offer significant complexity that have allowed some taxonomic groups to flourish. Understanding how urban-exploiting animals navigate this spatiotemporal heterogeneity is important given the continued global urban land expansion. Here, we examined the factors influencing resource-use in an urban community of ants, which represent a widespread and important taxon in urban ecosystems. In particular, we sought to integrate ants’ nutritional, thermal, and spatial niches to better understand how urban animals successfully access critical resources throughout their active season. Meteorological season (spring, summer, and fall) and/or species (n?=?9) influenced ants’ preferences for nutrition (ratio of ingested protein-to-carbohydrate ratio), as well as the temperature, type (impervious vs. non-impervious), and shade status (shaded vs. non-shaded) of surfaces used during activity. Our data also indicate links among habitat variables, as well as between nutritional preferences and habitat use. Together, our results suggest that species and seasonality influence ecological (combined nutritional, thermal, and spatial) niches in an urban community. We encourage future work in urban ecosystems that continues to integrate more features of the ecological niche, and to examine the outcomes of variation in niches (e.g., non-overlapping niches may explain both the persistence of some native animals and the success of invaders).     

Resource Dependence and Community Well‐Being in Rural Canada*

Abstract The well‐being of residents of resource dependent communities is a question of traditional interest to rural sociologists. The label “resource dependent” obscures how this relationship may vary between particular resource industries, regions, or indicators of well‐being. Few analyses have compared the relationship between well‐being and resource dependence across different industries, nor tested competing theories about the relationship between resource dependence and well‐being. Our paper presents an overview of the relationship between resource dependence—agriculture, fisheries, mining, energy, forestry—and human well‐being in Canada. Analysis of 1996 Statistics Canada data revealed a great deal of variation in the effect of “resource” dependence on indicators of well‐being (e.g., human capital, unemployment, income): some industries exhibit fairly positive outcomes (e.g., agriculture), others more negative outcomes (e.g., fishing). Consistent with analyses conducted in the United States, these relationships vary by region, suggesting the need for models that incorporate the particulars of place and industry.     

Anticipated dependence: A determinant in an integrative model of power relations among elderly couples

The study proposes an integrative, multivariate model for analysis of conjugal power relations among elderly married couples, from the perspective of the husband. The conceptual framework of the model is based on the well-known Resource Theory. However, in addition to the resources examined in other studies (e.g., economic and social resources), this model considers the husband's anticipated dependence on his wife as a potential factor that may explain conjugal power relations. The integrative model was tested on 211 elderly husbands in Israel. It was found that the primary variables explaining conjugal power relations in late adulthood are psychological-expressive in nature. Instrumental-economic resources were not found to have any explanatory power in the late stage of life. Traditional attitudes of the husband regarding the capacity of women to fulfill roles outside of the home correlated positively with his perceived power in the marital relationship. The findings indicate that the Resource Theory may be expanded and that anticipated dependence can be incorporated as a potential resource affecting current power relations among elderly couples.     

Posttraumatic symptoms following a campus shooting: the role of psychosocial resource loss

Conservation of resources (COR) theory has proven a useful framework for understanding posttrauma adjustment. A key tenet of this theory is the centrality of resource loss in determining adjustment. However, COR theory research has often been limited by retrospective research design, a focus on material loss (e.g., one's home), and a lack of attention to other adjustment predictors. This study examined whether psychosocial resource loss prospectively predicted PTSD symptomatology both immediately and 8 months following a campus shooting in a sample of college women (n = 691). Results supported that resource loss predicted symptomatology, even after controlling for other predictors, including prior trauma, psychological distress, initial PTSD symptomatology, and shooting exposure. Implications of the results for research and intervention following mass trauma are discussed.     

Human–environment interactions in South Florida's Everglades region: Systems of ecological degradation and restoration

This chapter examines the societal drivers of environmental change in South Florida's Everglades region during the past 150 years. This historical geography is developed through the use of a conceptual framework constructed to facilitate the analysis of human–environment interactions and nature–society systems of ecological degradation and restoration at the regional scale. The framework is composed of four basic interlinked components: interaction mechanisms (e.g., land use, direct resource utilization, pollution and external inputs, resource competition), feedback mechanisms (e.g., basic needs, quality of life, environmental ethics), control systems (e.g., governmental regimes, legal institutions, resource management), and the societal context (e.g., population and demographic patterns, social structure and organization, technology, economic conditions, societal values). A primary objective of this chapter is to determine the presence and importance of each of these components during the process of environmental change over the period of study—1845 to 1995.Data for the analysis are drawn from primary and secondary sources on the environmental, social, economic, and political history of South Florida. The results indicate that although elements of each component were present throughout the entire period, different elements of each component play more significant roles at differing moments. The shifts in importance are used to define four periods of environmental change within the region. The periods are the following: (1) frontier settlement (1845–1900), focused on basic needs acquisition and direct utilization of the resource base; (2) drainage and land conversion (1900–1930), focused on population and economic growth, land use change, and increased resource management and competition; (3) flood control and consolidation (1930–1950), focused on inputs from external sources and infusion of advanced technology, the development of governance and social structures, and increased concern for quality of life; (4) postwar boom, flood control, and water supply (1950–1970), focused on accelerated land use change, increased pollution, and further heightened concern for local quality of life; and (5) period of limits (1970–1995), focused on pollution and resource competition concerns, a developing regional environmental ethic and amenity values, and environmental preservation governance strategies.Taken together, the five periods represent the differing nature–society systems through which South Florida's regional ecosystem was degraded and which is now entering a phase of restoration.     

An object's categorizability impacts whether infants encode surface features into their object representations

Infants encode the surface features of simple, unfamiliar objects (e.g., red triangle) and the categorical identities of familiar, categorizable objects (e.g., car) into their representations of these objects. We asked whether 16–18-month-olds ignore non-diagnostic surface features (e.g., color) in favor of encoding an object's categorical identity (e.g., car) when objects are from familiar categories. In Experiment 1 (n = 18), we hid a categorizable object inside an opaque box. In No Switch trials, infants retrieved the object that was hidden. In Switch trials, infants retrieved a different object: an object from a different category (Between-Category-Switch trials) or a different object from the same category (Within-Category-Switch trials). We measured infants' subsequent searching in the box. Infants' pattern of searching suggested that only infants who completed a Within-Category-Switch trial as their first Switch trial encoded objects' surface features, and an exploratory analysis suggested that infants who completed a Between-Category-Switch trial as their first Switch trial only encoded objects' categories. In Experiment 2 (n = 18), we confirmed that these results were due to objects' categorizability. These results suggest infants may tailor the way they encode categorizable objects depending on which object dimensions are perceived to be task relevant.     

ENDOGENOUS DESTRUCTION IN CONFLICT: THEORY AND EXTENSIONS

This article develops a general equilibrium model of conflict to characterize the implications of endogenous destruction for bargaining and fighting. Specifically, we consider the scenario where two contending parties engage in bargaining to avoid fighting when there are direct costs (e.g., arms buildups) and indirect costs (e.g., destruction to consumable resources) of conflict. Without imposing specific functional form restrictions on conflict, production, and destruction technologies, we show their interactions in determining an optimal decision between fighting and bargaining. We find that, under the shadow of conflict, bargaining is costly as the contending parties always allocate more resources to arming for guarding settlement through bargaining than in the event of fighting. In contrast to conventional thinking that bargaining is Pareto superior over fighting, we show conditions under which fighting dominates bargaining as the Nash equilibrium choice. The positive analysis may help explain the general causes of fighting, without resorting to the assumption of incomplete information or misperceptions. (JEL D74, H56, C7)     

The mental health recovery movement and family therapy, part II: a collaborative, appreciative approach for supporting mental health recovery

A continuation of Part I, which introduced mental health recovery concepts to family therapists, Part II of this article outlines a collaborative, appreciative approach for working in recovery-oriented contexts. This approach draws primarily upon postmodern therapies, which have numerous social justice and strength-based practices that are easily adapted in recovery-oriented contexts. The model outlined in this article includes an overview of the recovery partnership (i.e., therapeutic relationship), mapping recovery (i.e., assessment and case conceptualization), recovery planning (i.e., treatment planning), facilitating recovery (i.e., intervention), accessing resources (i.e., case management), recovery maintenance, and service contexts as well as a case study.     

Social Exchange Theory and the Division of Household Labor in Same-Sex Couples

Same-sex couples are often not seen as a family unit and are excluded from research, including family research on topics such as household division of labor. The author examined division of household labor, using social exchange theory, among 165 survey respondents in a same-sex relationship. Division of labor was measured by the percentage of tasks performed according to the respondent. Status differences between partners (e.g., higher, equal, lower) in terms of income, education, hours spent on paid labor outside the home, employment status, age, and race (here, only same or different races) were the independent variables. In general, as predicted by social exchange theory, partners with greater resources or power performed fewer household tasks. Satisfaction with division of labor and sense of being appreciated for one's contributions to household tasks were positively correlated with global relationship satisfaction. However, some inconsistencies indicate gaps in social exchange theory and that other factors may be important in understanding division of labor among same-sex couples.     

Feasibility,Acceptability, and Initial Efficacy of an Online Sexual Health Promotion Program for LGBT Youth: The Queer Sex Ed Intervention

Lesbian, gay, bisexual, and transgender (LGBT) youth experience multiple sexual health inequities driven, in part, by deficits in parental and peer support, school-based sex education programs, and community services. Research suggests that the Internet may be an important resource in the development of sexual health among LGBT youth. We examined the feasibility of recruiting youth in same-sex relationships into an online sexual health intervention, evaluated intervention acceptability, and obtained initial estimates of intervention efficacy. LGBT youth (16 to 20 years old) completed Queer Sex Ed (QSE), an online, multimedia sexual health intervention consisting of five modules. The final sample (N = 202) completed the pretest, intervention, and posttest assessments. The primary study outcomes were sexual orientation identity and self-acceptance (e.g., coming-out self-efficacy), sexual health knowledge (e.g., sexual functioning), relationship variables (e.g., communication skills), and safer sex (e.g., sexual assertiveness). Analyses indicated that 15 of the 17 outcomes were found to be significant (p < .05). Effect sizes ranged from small for sexual orientation (e.g., internalized homophobia) and relationship variables (e.g., communication skills) to moderate for safer sex (e.g., contraceptive knowledge) outcomes. This study demonstrated the feasibility, acceptability, and initial efficacy of QSE, an innovative online comprehensive sexual health program for LGBT youth.     

Disparities in Access to Health Care Among Middle-Aged and Older Adults with Disabilities

Disability is increasing among middle-aged adults and, reversing earlier trends, increasing among older adults as well. Disability is experienced disproportionately by Black and lower socioeconomic status (SES) individuals. We used Medical Expenditure Panel Survey data to examine health care disparities in access to health care for middle-aged (31 to 64 years of age) and older (65+ years of age) adults with disabilities by race and ethnicity, education, and income (n = 13,174). Using logistic regression, we examined three measures of potential (e.g., usual source of care), and three measures of realized (e.g., counseling related to smoking) access. Middle-aged and older minority individuals with disabilities had lower relative risks of having usual sources of care and higher relative risks of having suboptimal usual sources of care (e.g., a place rather than a person) than White adults with disabilities. There were SES effects observed for middle-aged adults with disabilities across most measures that were, for certain measures, more pronounced than SES effects among older adults with disabilities. These findings are important, since health resources (e.g., a usual source of care) may mediate relations among disability, morbidity, and mortality. Policy actions that may mitigate the disparities we observed include financial incentives to support access to an optimal usual source of care and mechanisms to foster behavioral interventions related to smoking and exercise. Ensuring that these actions address the specific concerns of individuals with disabilities, such as physical accessibility and provider cultural competency, is essential.     

The Treatment of Relationship Status in Research on Dating and Mate Selection

The relationship status of study participants (e.g., daters, cohabitors, marrieds, or unmarrieds) has implications for understanding dating and mate selection. Procedures used in studies may blur or ignore status distinctions. The authors examined methods used in 791 studies published from 1991 – 2001. Most commonly, status of participants is unspecified, and different statuses are collapsed for analysis. Status of participants is associated with recruitment method, and type (e.g., romantic, friendship) and form (e.g., perceived, current) of relationship measured. Unspecified samples are associated with research on the topics of universal properties or causal conditions, and specified samples with mate selection. The connection between status and topic is becoming more blurred over time. Recommendations for studying and reporting status are provided.     

“Then it's clear who owns the trees”: Common Property and Private Control in the Social Forest in a Zimbabwean Resettlement Area1

ABSTRACT The woodlands in the Resettlement Areas of post-Independence Zimbabwe are under severe stress. The recent Land Tenure Commission (Rukuni 1994), identified the problem as the common property management system in the woodlands, and recommended a change to private tenure. The government of Zimbabwe has accepted this recommendation. This paper explores the common property woodland management system in a case study of a Model A resettlement scheme in order to consider this policy shift. Key institutional inadequacies and widespread “poaching” of resources by neighboring communities emerge as the major micro causes for deforestation in common property areas. In addition, private control in some areas of the woodlands appears to have positive effects. While these dynamics at first appear to support the shift to private tenure, doubts emerge when the woodland management system is placed in historical cultural context, and the poaching problem is seen as an aspect of the macro context of overall inequity in land and resource distribution.     

Minority Stress and Stress Proliferation Among Same‐Sex and Other Marginalized Couples

Drawing from 2 largely isolated approaches to the study of social stress—stress proliferation and minority stress—the authors theorize about stress and mental health among same‐sex couples. With this integrated stress framework, they hypothesized that couple‐level minority stressors may be experienced by individual partners and jointly by couples as a result of the stigmatized status of their same‐sex relationship—a novel concept. They also consider dyadic minority stress processes, which result from the relational experience of individual‐level minority stressors between partners. Because this framework includes stressors emanating from both status‐based (e.g., sexual minority) and role‐based (e.g., partner) stress domains, it facilitates the study of stress proliferation linking minority stress (e.g., discrimination), more commonly experienced relational stress (e.g., conflict), and mental health. This framework can be applied to the study of stress and health among other marginalized couples, such as interracial/ethnic, interfaith, and age‐discrepant couples.     

Allocation of resources in asymmetric competitions: How do the weak maintain a chance of winning?

To maintain a chance of occasionally beating a stronger player in a competition waged over several fields, a weaker player should give up on some of the fields and concentrate resources on the remaining ones. But when do weak players actually do this? And which fields do they give up when the fields differ in their likelihood of being assessed? We report an experimental study of resource allocation in which asymmetric pairs of players compete over asymmetric fields. Symmetric players and symmetric fields are used for control. We find that players behave as follows: (1) Average wins are the same in the symmetric and asymmetric fields conditions and correspond to relative player strength. (2) The proportion of fields given up on decreases with a player’s greater relative strength, increases for asymmetric field likelihoods, and increases when competitions are framed in meaningful context; this proportion is related to wins. (3) When field likelihoods are asymmetric, players’ resource allocation is correlated with likelihood. Wins generally increase with that correlation but the relation is different for players of different strength. (4) The proportion of fields given up on and the correlation with likelihood change with experience towards the values corresponding to higher wins.     

Understanding the Importance of Organizational Resources to Explain Organizational Problems: Evidence from Nonprofit Sport Clubs in Germany

Nonprofit sport clubs experience organizational problems regarding the recruitment and retention of members, volunteers, and coaches, and the financial situation of the club. The purpose of this study is to investigate the impact of different types of organizational resources on the severity of organizational problems. A theoretical framework based on the concept of organizational capacity is presented, which explains the influence of human, financial, infrastructure, and cultural resources on organizational problems. The empirical evaluation is undertaken using data from a nationwide online survey of nonprofit sport clubs in Germany (n = 19,345). The regression results show that human resources (women on the board, secondary volunteers, etc.), financial resources (Herfindahl index), infrastructure resources (own facilities, and public facilities), and cultural resources (e.g., strategic policy, formation policy, value of conviviality, and variety of sports) are significant determinants of organizational problems. The findings of this study have implications for the management of voluntary sport organizations.     

Team-Teaching Anti-Oppression with Diverse Faculty: Challenges and Opportunities

Team-teaching, especially with colleagues who are diverse along a number of domains of social identity (e.g., social class, gender, race, tenure rank, academic status, age), represents a rich opportunity to model a social justice, anti-oppressive approach to teaching and learning. In this article, we present pedagogical strategies to consider when team-teaching foundation social work courses with a social justice focus. Constructs related to power dynamics, privilege, social class, microaggressions and social identity are explored. Development of teaching plans, managing challenging team dynamics, and teaching methods are examined. Implications of team-teaching anti-oppression content for social work education are discussed.     

Managing human resource shortages in a unionized setting: Best practices in air traffic control

Human resource shortages require effective human resource management (HRM). Findings from research about ongoing labor shortages in air traffic control (ATC) are used to build a preliminary theory of appropriate HRM responses. Our international sample of major ATC agencies generally developed a set of best HRM practices to attract, motivate, and retain human assets. Key factors included (1) cultural and institutional norms, (2) technological change, (3) union responses, and (4) organizational form and structure (e.g., civil service versus commercial firms). While ATC’s rare human aptitudes, lengthy training to develop firm-specific human capital, and lifelong employment may limit the preliminary theory’s general applicability, crucial lessons emerge about human resource planning. This research was conducted with the support of the Social Sciences and Humanities Research Council, the Rice Fellowship, the Ziegler Fellowship, and the Center for International Business Studies at the University of Alberta. We are indebted to the individuals interviewed.     

“I'll Give You the World”: Socioeconomic Differences in Parental Support of Adult Children

Research has shown that parents with higher socioeconomic status provide more resources to their children during childhood and adolescence. The authors asked whether similar effects associated with parental socioeconomic position are extended to adult children. Middle‐aged parents (N = 633) from the Family Exchanges Study reported support they provided to their grown children and coresidence with grown children (N = 1,384). Parents with higher income provided more emotional and material support to the average children. Grown children of parents with less education were more likely to coreside with them. Parental resources (e.g., being married) and demands (e.g., family size) explained these patterns. Of interest is that lower income parents provided more total support to all children (except total financial support). Lower income families may experience a double jeopardy; each grown child receives less support on average, but parents exert greater efforts providing more total support to all their children.
