Laura M. Koehly is Senior Investigator and Chief, Social and Behavioral Research Branch at the National Human Genome Research Institute. Her research focuses on developing and applying social network methods to the study of complex social systems, such as families and communities. In order to better understand the impact of the interpersonal environment on behaviors, Laura Koehly also develops statistical methods to examine the perspectives of all members within a family system, thereby considering the social context in which at-risk individuals live.

Abstract:
In the United States, approximately 66 million informal (unpaid) caregivers provide care to someone who is ill, disabled or are experiencing loss of function associated with aging; approximately 4.7 million perform such roles in Germany. These caregivers may be adult children, spouses, parents, or other social network members. Caregiving research has traditionally engaged a single-informant, primary caregiver approach to characterize the caregiving network composition and function. However, multiple family members are affected by caregiving and may experience it differently. In the current talk, we examine the added value of the multi-informant approach to characterize the social landscape of caregiving within the context of Alzheimer’s disease and related dementia (ADRD). Our data come from the Caregiving Roles and Expectations Networks (CaRENet) Project in which 72 informants from 30 families enumerated network members and indicated caregiving roles for each. We observe both within family and between family variability with respect to caregiving roles and expectations. These results provide evidence for moving beyond a sole primary caregiver model, suggesting the need to move towards a multi-informant approach when designing caregiving studies and interventions. In addition, network-level factors derived from such an approach may be important to family adaptation and caregiver well-being.

Persönliche Beziehungen - Familien-, Freundschafts- oder Nachbarschaftsbeziehungen - sind von zentraler Bedeutung für die soziale Integration: Sie vermitteln Zugehörigkeit und Entspannung, sie informieren, motivieren und stellen Rollenmodelle bereit. Persönliche Beziehungen leisten Unterstützung und materielle Unterstützung und sind wesentliche Quellen gesamtgesellschaftlicher Wohlfahrtsproduktion. Persönliche Beziehungen verändern sich jedoch, insbesondere ändert sich die Zusammensetzung des „sozialen Convois“, der Menschen im Laufe des Lebens begleitet. Die Beziehungen, ihre Leistungen und die Frage, wie und auf welche Weise sich die persönlichen Beziehungen und Netzwerke im Leben verändern stehen im Mittelpunkt des Vortrags.

Der Vortrag findet statt im Rahmen der Veranstaltungsreihe "Einfach Wissenswert: Sozialwissenschaften" und ist Teil der Reihe "Wissen um 11". Er dauert in der Regel 30 Minuten mit einer anschließenden Diskussionsrunde von ca. 15 Minuten. Der Eintritt ist frei.

Wenn es um Gesellschaft geht, dann sind Beziehungen das Thema - oder vielmehr Beziehungsgeflechte. Aber wie funktionieren Beziehungsgeflechte und wie verändern sie sich?
Die Ausstellung steht unter dem Motto "Ich und die Anderen". Ausgehend vom Ich, von der individuellen Position des Besuchers, zeigt sie an 13 Beispielen, wie und woran Bremer Sozialwissenschaftler und Sozialwissenschaftlerinnen arbeiten. So lässt sich zum Beispiel der gesellschaftliche Zusammenhalt in verschiedenen Ländern vergleichen und der Frage nachgehen, wie es um Hilfsbereitschaft oder gesellschaftliche Teilhabe in Bremen steht. Ein weiteres Thema sind kurze Wege durch das riesige Netzwerk der Gesellschaft, über die sich Kontakte in andere Milieus ergeben.
Sozialwissenschaftliche Arbeit wird nicht nur vorgestellt, sondern auch praktiziert. So fragt ein anderes Projekt nach hafenstädtischen Mentalitäten, die das Verschwinden der Häfen aus den Städten überdauert haben. Wie sieht es in Bremen aus?

Dimitris' current research interests are on networks of political and business actors, political and policy entrepreneurship and social entrepreneur motivation. The unifying theme in his work is a focus on exceptional agency and relations as expressed in the networks of leaders and entrepreneurs.

Abstract:
Relations between agents (i.e. networks) act as conduits to their political power. And power is channeled to the attainment of governance outcomes. Traditional social science makes the simplifying assumption that actor preferences (their perceived utility) can be employed to predict their behaviour. By comparison an analysis of networks makes actor interdependence the point of departure to an understanding of their constraints and opportunities. In that respect actors can impact outcomes not only through their own discrete interventions, but also mediated by the pattern of interaction among others.

Governance as the product of political exchange is therefore affected by the quality of the interaction between political agents, what Jones and Robins et al. have termed governance embeddedness. For instance, the degree to which political agents reciprocate relations equitably, whether there is transitivity, and whether relations are predominantly hierarchical. Governance as a process is affected by the pattern of exchange between political actors. For instance, the degree to which there is a strong core-periphery, the multiplicity of clusters, prevalence of brokers or the skewness in the distribution of ties can affect the way politics is exercised and policies are created.

I employ a range of case studies of policy making, policy implementation and cross-border policy in Europe, to demonstrate how governance process and governance outcomes are affected by the networks of political agents. This often happens in ways that can only be comprehended by analyzing the pattern of actor relations. I also use examples that draw from cases of environmental policy and the recent debates on sustainability to hypothesize on the nature of governance resilience. This analysis is coached within the literature of leadership, political entrepreneurship and brokerage or what some have termed exceptional agency.

Abstract:
Visone (ital. mink) is a free software tool that combines comprehensive means for analysis with unique visualization capabilities. It can also be used as a graphical frontend to R, RSiena, and KNIME.

This is a hands-on introduction to visone. After a brief overview of its design and features, we will explore some of its core functionality. Using exemplary network analyses, we will produce presentations of findings step-by-step, starting from data input to arrive at publication quality information visualizations, including time-coherent animations of longitudinal networks.

It is advisable to bring a laptop running Windows, MacOS, or Linux. The software is written in Java and can be installed from www.visone.info. It features many standard and non-standard methods for analysis and visualization of networks, and a powerful graphical user interface. It's native file format is GraphML, allowing for arbitrarily many attributes of nodes, links, and networks, but other formats such as CSV tables, UCINet DL, Pajek .net, etc., can be imported. Visualizations can be exported as pdf, png, tiff, animated svg, or Windows metafiles.

Abstract:
The positional approach is a recent methodological innovation intended to narrow the gap between substantive theory and mathematical analysis of social networks. Breaking down current methods into meaningful and manageable decision steps it explicates hitherto tacit assumptions, suggests means to overcome them, and smoothly generalizes approaches to valued, multiplex, multilevel, and temporal data. It also facilitates the incorporation of more qualitative observations and produces more nuanced results.

All of this is achieved by defining the network position of an actor as the aggregate of direct and indirect relationships and attributes. Starting from the key concept of position, state-of-the-art methods of analysis turn out to be special cases of positional comparisons and evaluation. The characterization of actors by their positions can be thought of as a form of conjoint measurement, and exploits a richer array of non-quantitative mathematical tools.

Methodologically, this allows to separate the substantive argumentation of what defines a position from the formal analysis of the network it is embedded in. An important benefit of the genericity of the positional approach is that it unifies existing methods and at the same time suggests many new methods obtained from alternative instantiations. Moreover, it facilitates basic research by identifying relevant problems without requiring domain-specific background knowledge.

The workshop is an introduction to the positional approach starting from first principles. It is centered around use cases that cover a broad range of social network application domains. We will discuss the relative utility of positional and current state-of-the-art approaches and identify how method selection can be better informed by substantive theory. In a special closing session, we will discuss positional approaches to participant-contributed research problems.

Abstract:
The visualization social networks is a matter of choosing an effective design for the substance of interest. This is a difficult task by itself, but it is further complicated when the data render the design unsuitable. Following a general introduction to social network visualization, we will focus on the special case of networks which exhibit the small-world property. They are notoriously difficult to visualize because the relatively short distances cause most layout algorithms to create hairball-like diagrams. We will discuss an approach to untangle such hairballs by separating cohesive subgroups using the structural embeddedness of ties.
