The Iceberg and the Cheese

David Lankes has warned us of shortsightedness, risk aversion, and avoidance of new roles, while David Weinberger saw a great opportunity for us to position the library as a platform. This session addresses the threat and seizes the opportunity. Our tried-and-true Libguides platform, pushed to the limit, is a way to expand our role by sharing knowledge of all kinds, with everyone, across all departments in our institutions. Join us to see how it can be done

Lower Karroo (Permlan) Acanthomorphitae Acritarchs from South Africa

Main articleEight populations of fifty individuals of Acritarchs from the Permian marine horizons of South Africa are statistically analysed and assigned to two species of Micrhystridium. The use of the multivariate discriminant function and Mahalanobis-D2 as a taxonomic tool in distinguishing populations and species that have but few measurable variables is briefly discussed and the possibility of using such techniques to determine stratigraphic position in lineage studies noted.Non

Miospore zones in Karroo sediments of Tanzania

Main articleMiospore complexes from Karroo rocks of parts of the Songwe-Kiwira Coalfield and Ketewaka-Mchuchuma Coalfield, Tanzania, are described and correlated one with the other. The complexes are assigned to the lower part of the Permian System.Non

Vertex-Unfoldings of Simplicial Polyhedra

We present two algorithms for unfolding the surface of any polyhedron, all of whose faces are triangles, to a nonoverlapping, connected planar layout. The surface is cut only along polyhedron edges. The layout is connected, but it may have a disconnected interior: the triangles are connected at vertices, but not necessarily joined along edges.Comment: 10 pages; 7 figures; 8 reference

Complexity and incongruity in habituation of GSR, investigation, and preference

Thesis (Ph.D.)--Boston University.BACKGROUND AND INTRODUCTION Although the last fifteen years have seen a considerable increase of interest in (1) exploratory and investigatory behavior and (2) psychological arousal, there are little data relating these two topics directly. This study attempts to show such a relationship. The orientation react ion is a pattern or skeletal, sensory, autonomic and central nervous system responses which is frequently elicited by a single sudden change along any one of a variety of dimensions of stimulation. It is often interpreted as serving to increase readiness to act by directing attention toward specific environmental changes, and can be assumed to entail a rise in arousal [TRUNCATED

Structural vulnerability to narcotics-driven firearm violence: An ethnographic and epidemiological study of Philadelphia's Puerto Rican inner-city.

BackgroundThe United States is experiencing a continuing crisis of gun violence, and economically marginalized and racially segregated inner-city areas are among the most affected. To decrease this violence, public health interventions must engage with the complex social factors and structural drivers-especially with regard to the clandestine sale of narcotics-that have turned the neighborhood streets of specific vulnerable subgroups into concrete killing fields. Here we present a mixed-methods ethnographic and epidemiological assessment of narcotics-driven firearm violence in Philadelphia's impoverished, majority Puerto Rican neighborhoods.MethodsUsing an exploratory sequential study design, we formulated hypotheses about ethnic/racial vulnerability to violence, based on half a dozen years of intensive participant-observation ethnographic fieldwork. We subsequently tested them statistically, by combining geo-referenced incidents of narcotics- and firearm-related crime from the Philadelphia police department with census information representing race and poverty levels. We explored the racialized relationships between poverty, narcotics, and violence, melding ethnography, graphing, and Poisson regression.FindingsEven controlling for poverty levels, impoverished majority-Puerto Rican areas in Philadelphia are exposed to significantly higher levels of gun violence than majority-white or black neighborhoods. Our mixed methods data suggest that this reflects the unique social position of these neighborhoods as a racial meeting ground in deeply segregated Philadelphia, which has converted them into a retail endpoint for the sale of astronomical levels of narcotics.ImplicationsWe document racial/ethnic and economic disparities in exposure to firearm violence and contextualize them ethnographically in the lived experience of community members. The exceptionally concentrated and high-volume retail narcotics trade, and the violence it generates in Philadelphia's poor Puerto Rican neighborhoods, reflect unique structural vulnerability and cultural factors. For most young people in these areas, the narcotics economy is the most readily accessible form of employment and social mobility. The performance of violence is an implicit part of survival in these lucrative, illegal narcotics markets, as well as in the overcrowded jails and prisons through which entry-level sellers cycle chronically. To address the structural drivers of violence, an inner-city Marshall Plan is needed that should include well-funded formal employment programs, gun control, re-training police officers to curb the routinization of brutality, reform of criminal justice to prioritize rehabilitation over punishment, and decriminalization of narcotics possession and low-level sales
