The networked seceder model: Group formation in social and economic systems

The seceder model illustrates how the desire to be different than the average can lead to formation of groups in a population. We turn the original, agent based, seceder model into a model of network evolution. We find that the structural characteristics our model closely matches empirical social networks. Statistics for the dynamics of group formation are also given. Extensions of the model to networks of companies are also discussed

Economic nationalism and the cultural politics of consumption under austerity: the rise of ethnocentric consumption in Greece

By nuancing the politics of consumption in the context of austerity, this article highlights the rise of economic nationalism and the reconfiguration of consumer cultures at the aftermath of the global financial crisis. As it argues, in the context of Greece, three types of consumer culture have manifested; these are evoking consumption as resilience, resistance or reinforcement. This work focuses on the latter through the phenomenon of ethnocentric consumption, which is part and parcel of economic nationalism. Economic nationalism can be explored through promotion of ethnocentric consumption and is demonstrable both in the inception and constitution of nation states, but also in times of crisis. This article critically appraises ethnocentric consumption as consumption based on ethnocentric criteria (natural resources, ownership, production, manufacturing, distribution and labour force). In the context of the crisis in Greece, economic nationalism has become manifest as a solution to the national economy. The specific case chosen is a citizens’ movement and its campaign for the promotion of ethnocentric consumption. A close examination of the campaign (We Consume What We Produce) reveals the historical alignment of the state’s and citizens’ economic interests, the reverberation of state narrative from the 1980s and exclusionary nationalism which is also used by fascists. Campaigns for ethnocentric consumption limit the creativity of consumer politics. First, this phenomena appears to be an alternative vehicle for political parties. Second, it is tied around a normative narrative of economic recovery, which is particularly mythological. Third, its overall target is to maximise competitiveness on a global scale, and finally, it demonstrates a densely dangerous relationship with economic nationalism. Yet, it is important to situate this phenomenon within the context of consumer cultures under austerity, especially as more creative modalities of social economy initiatives by grassroots groups have been re-socialising the market

COVID‐19, nationalism, and the politics of crisis: A scholarly exchange

In this article, several scholars of nationalism discuss the potential for the COVID‐19 pandemic to impact the development of nationalism and world politics. To structure the discussion, the contributors respond to three questions: (1) how should we understand the relationship between nationalism and COVID‐19; (2) will COVID‐19 fuel ethnic and nationalist conflict; and (3) will COVID‐19 reinforce or erode the nation‐state in the long run? The contributors formulated their responses to these questions near to the outset of the pandemic, amid intense uncertainty. This made it acutely difficult, if not impossible, to make predictions. Nevertheless, it was felt that a historically and theoretically informed discussion would shed light on the types of political processes that could be triggered by the COVID‐19 pandemic. In doing so, the aim is to help orient researchers and policy‐makers as they grapple with what has rapidly become the most urgent issue of our times

Biological, Social, and Urban Design Factors Affecting Young Street Tree Mortality in New York City

In dense metropolitan areas, there are many factors including traffic congestion, building development and social organizations that may impact the health of street trees. The focus of this study is to better understand how social, biological and urban design factors affect the mortality rates of newly planted street trees. Prior analyses of street trees planted by the New York City Department of Parks & Recreation between 1999 and 2003 (n=45,094) found 91.3% of those trees were alive after two years and 8.7% were either standing dead or missing completely. Using a site assessment tool, a randomly selected sample of 13,405 of these trees was surveyed throughout the City of New York during the summers of 2006 and 2007. Overall, 74.3% of the sample trees were alive when surveyed and the remainder were either standing dead or missing. Results of our initial analyses reveal that highest mortality rates occur within the first few years after planting, and that land use has a significant effect on street tree mortality. Trees planted in one- and two-family residential areas had the highest survival rates (82.7%), while young street trees planted in industrial areas, open space and vacant land had the lowest rates of street tree survival (60.3% -62.9%). Also significant in predicting street tree success and failure are species type, tree pit enhancements, direct tree care/stewardship, and local traffic conditions. These results are intended to inform urban forest managers in making decisions about the best conditions for planting new street trees

The social construction of violence among Northern Plains tribal members with antisocial personality disorder and alcohol use disorder

Whereas recent reports from national studies have presented extremely high rates for many personality disorders in American Indian communities, persistent concerns about the meaning of these symptoms have left many troubled by these reports. American Indians as a group are known to suffer disproportionately from a number of violent experiences, but the dynamics of this violence have received little attention. This paper examines perspectives on violence in the lives of 15 northern plains tribal members who met criteria for antisocial personality disorder and comorbid alcohol use disorder. It explores how study participants constructed and understood their own violent encounters, as well as the motivations they described (characterized here as reputation, leveling, retaliation, catharsis, and self-defense). Violence was gendered in this study, with men generally presenting as perpetrators and women as victims. Men often described themselves as ready participants in a violent world, while women were quite clear that aggression for them was often simply required as they tried to defend themselves from male violence. While this analysis does not replace clinical analyses of violence in antisocial personality disorder, it does reveal an underlying cultural logic that may play a role in shaping the recourse to violence for that minority of individuals for whom it appears to be the obvious choice.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Reunifying from behind bars: A quantitative study of the relationship between parental incarceration, service use, and foster care reunification

Incarcerated parents attempting to reunify with their children in foster care can find it difficult to complete the activities on their court-ordered case plans, such as drug treatment services and visitation with children. Although much has been written regarding the obstacles that are likely to interfere with reunification for incarcerated parents, very little quantitative research has examined the topic. This study uses secondary data to examine the incarceration experiences and reunification outcomes of a sample of 225 parents in one large urban California county. In multivariate analysis controlling for problems and demographics, incarcerated parents were less likely to reunify with their children; however, service use appeared to mediate this relationship, as the negative association between incarceration and reunification did not persist when service use was included as a variable in the model. Suggestions are made for policy and practice changes to improve reunification outcomes for this population of parents.
