Perfect octagon quadrangle systems with upper C4-systems

An octagon quadrangle is the graph consisting of an 8-cycle (x₁, x₂,…, x₈) with two additional chords: the edges {x₁, x₄} and {x₅, x₈}. An octagon quadrangle system of order v and index ρ [OQS] is a pair (X,H), where X is a finite set of v vertices and H is a collection of edge disjoint octagon quadrangles (called blocks) which partition the edge set of ρK_v defined on X. An octagon quadrangle systemΣ=(X,H) of order v and index λ is said to be upper C₄-perfect if the collection of all of the upper4-cycles contained in the octagon quadrangles form a μ-fold 4-cycle system of order v; it is said to be upper strongly perfect, if the collection of all of the upper4-cycles contained in the octagon quadrangles form a μ-fold 4-cycle system of order v and also the collection of all of the outside8-cycles contained in the octagon quadrangles form a ?-fold 8-cycle system of order v. In this paper, the authors determine the spectrum for these systems.     

Communicating About Xenotransplantation: Models and Scenarios

Xenotransplantation entails using organs from genetically modified animals as a way to solve the shortage of human organs for transplantation. As with other novel technologies, if xenotransplantation is to be judged fairly, proponents must explain its complex, uncertain, and unfamiliar risks and benefits. Xenotransplantation's risks include the possibility of a recombinant virus infecting human transplant recipients, potentially causing an epidemic of an unfamiliar disease. Using materials vetted by scientific experts, we communicated the variables and relationships determining this risk in three formally equivalent formats: (a) a graphic model, (b) scenarios structured by the graphic model, and (c) both the model and the scenarios. Participants were randomly assigned to receiving one set of materials. They rated them as equally clear and studied them equally long, suggesting similar ease of cognitive processing. Compared to participants receiving the scenarios, those who received the graphic model better identified causes and effects of the risk, and saw less risk of xenotransplantation. Participants who received both the model and the scenarios generally showed intermediate responses. The study demonstrates a general procedure for developing and evaluating formally equivalent graphic and scenario communications regarding highly uncertain risks. In this application to xenotransplantation, presenting a graphic representation improved people's understanding of the risk.     

Global movement dilemmas: transnational representation and impact in the World Social Forum

ABSTRACT

Various social movement debates on organizational design have hinged on the possibility and political usefulness of devising post-representational, a-representational or anti-representational spaces. We analyse organizational options and obstacles that the WSF faces. A denial of representational dynamics may leave internal power and structural imbalances unattended. We raise the question whether the WSF process can intersect the current instances of activism across the planet including the climate justice movement. We explore its changing attitudes toward representational decision-making. Finally, we suggest that the relationship between traditional organization-building and internet-mediated decision-making practices developing at the intersection between the local, the global and the virtual could be debated on the road to the next global WSF, likely to take place in Mexico.     

Measuring university-based research in Europe: competing indicators and underlying assumptions

Modern societies have a growing need for information and numbers for governing social life. Numbers have the ability to represent a complex reality in a simplified and linear form, easily communicated. Far from being the product of a mere technical process, numbers are the result of a process that “is fundamentally social – an artifact of human action, imagination, ambition, accomplishment” (Espeland, W.N., and Stevens, M.L., 2008. A sociology of quantification. European journal of sociology, 49 (3), 401–436, p. 431). In the modern policy-making climate, numbers become key mechanisms for simplifying, classifying, comparing and evaluating. Along with this, the fields of visibility of evaluative objects, meanings and understandings (Dean, M., 2010. Governmentality. Power and rule in modern societies. 2nd ed. London: Sage) are re-framed consistently with what Clarke, J. (2004. Changing welfare, changing states. New direction in social policy. London: Sage) terms a ‘performance/evaluation nexus’ that links effort, values, purposes and self-understanding to measures and comparisons of outputs (Ball, S.J., 2012. Performativity, commodification and commitment: an I-Spy guide to the neoliberal university. British journal of educational studies, 601, 17–28). In this paper, we focus on the field of higher education (HE), where numbers, in the form of performance indicators, benchmarks and headline targets, are frequently used to strategically orient the sector towards the objectives and goals of the Bologna Process and of the overall Europe 2020 agenda (Waldow, F., 2014. From taylor to tyler to no child left behind: legitimating educational standards. Prospects, 45 (1), 49–62). We aim to offer a comparative overview of the complex spectrum of metrics, provided at the supranational level, within the field of higher education by focusing on the European Research Area (ERA) in order to map and analyse some of the crucial issues in play. A second ambition of this paper is to move from a mapping and analytical perspective to a deconstruction of a specific subset of research metrics, with the aim of challenging the ‘self-evident truths’ and the dominant conventional wisdom that define current European metrics in order to bring into question whether they contribute to restructuring the universities’ research environments, affecting research policies and procedures. Performance indicators are posited to be‘conceptual technologies’, encompassing theoretical and normative assumptions that shape the objects they aspire to measure.     

Women Constructing Masculinity in Voluntary Firefighting

Within gender studies, research and theorizing have used archetypal ‘masculine’ occupations to explore how masculinity is accomplished and practised in social interaction. In contrast, little work has explored how masculinity is constructed in the voluntary sector. In this paper, we address this gap by exploring how masculinity is constructed and experienced by women volunteers who are active firefighters in rural and regional Victoria. Firefighting is widely recognized as a non‐traditional occupation for women and they are underrepresented as volunteers as well as paid employees. We explore masculinity from the perspective of women volunteers because this can enhance our understanding of masculinity as a relational achievement as well as help to identify practices that they experience as problematic. Our research shows how voluntary work can afford a distinct range of resources for the ‘doing’ of gender and how this reflects the specific organizational and geographical contexts in which such volunteering occurs.     

The role of dispersal and local environment in urban land snail assemblages: an example of three cities in Central Italy

Ecologists increasingly appreciate the central role that urban biodiversity plays in ecosystems, however much urban biodiversity is neglected, especially some very diverse groups of invertebrates. For the first time in southern Europe, land snail communities are analysed in four urban habitats along a geographical gradient of three cities, using quantitative methods and assessing the relative roles of local environmental conditions (“distance from sea”, “distance from city centre”, “vegetation cover”) and spatial effects by principal coordinate analysis of neighbour matrices, redundancy analysis and variation partitioning. A total of 53 species was recorded, a richness similar to that of natural areas. At habitat level, species richness did not show a clear increasing trend from more to less urbanized habitats, but rather a homogeneous pattern. At city level, study areas hosted rather heterogeneous species assemblages and biotic homogenization did not seem to have any impact; indeed, only three species could be considered alien. Variation partitioning showed that land snail communities were mostly structured by environmental factors, even when spatial structures independent of measured environmental variables were included: “vegetation cover” and “distance from city centre” were the environmental variables that explained most of the variation in species composition. The lack of strong spatial structure also unexpectedly suggested that transport by humans aids dispersal of organisms with low mobility, which are usually limited by spatial constraints in natural environments. These results provide ecological and conservation implications for other invertebrate groups, suggesting to set priorities in management strategies that include habitat conservation at local scale.     

Three-way association measure decompositions: The Delta index

In this paper we describe a general framework to decompose three-way association measures for contingency tables, in particular symmetric and non-symmetric measures will be discussed, like Pearson's index, Marcotorchino's index, whose special case is the Gray–Williams index, and a new non-symmetric one will be proposed, called the Delta index. After showing the orthogonal decomposition of these indices, practical examples illustrating the different decompositions will be given.
