Who will help prevent sexual violence: Creating an ecological model of bystander intervention

Abstract: Given the prevalence of sexual and relationship violence in communities, innovations in prevention are sought. One promising line of inquiry directs efforts not at victims or perpetrators but at community members who are potential witnesses to high-risk events along the continuum of violence or who may need to support victims after an assault. To date, the main organizing framework for understanding bystander behavior is the work of Latane and Darley (1970), who described a series of stages that lead to an individual’s decision to intervene or not when someone needs help. Yet this model focuses mainly on factors within the individual or his or her immediate context. In the current review, I use ecological models by Bronfenbrenner (1977, 2005) and Kelly (2006) to expand our view of key factors that help promote and may serve as barriers to helpful bystander intervention. For example, ecological theories suggest important community-level variables, such as campus size or cultural values, that may influence the degree of helping and may, in some instances, be leverage points for creating change.

Understanding Process From Within: An Argument for ‘Withness’-Thinking

Abstract: If our task is simply that of theorizing process, then there are many brilliant writers and thinkers in the recent past to turn to. But as I see it, these writers are mostly oriented toward helping us think about process ‘from the outside’, about processes that we merely observe as happening ‘over there’. But if we are to rethink appropriate styles of empirical research, then we need a different form of engaged, responsive thinking, acting, and talking, that allows us to affect the flow of processes from within our living involvement with them. Crucially, this kind of responsive understanding only becomes available to us in our relations with living forms when we enter into dialogically structured relations with them. It remains utterly unavailable to us as external observers. I will call this kind of thinking, ‘thinking-from-within’ or ‘withness-thinking’, to contrast it with the ‘aboutness-thinking’ that is more familiar to us. What we can gain in our understandings-from-within, is a subsidiary awarenes...

Search for a new gauge boson in electron-nucleus fixed-target scattering by the APEX experiment.

Abstract: We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α' to electrons. Such a particle A' can be produced in electron-nucleus fixed-target scattering and then decay to an e + e- pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175-250 MeV, found no evidence for an A'→ e+ e- reaction, and set an upper limit of α'/α ~/= 10(-6). Our findings demonstrate that fixed-target searches can explore a new, wide, and important range of masses and couplings for sub-GeV forces.

Long-term effects of experimental nitrogen additions on foliar litter decay and humus formation in forest ecosystems

Abstract: Decomposition rates and N dynamics of foliar litter from 4 tree species were measured over a 72 month period on the Chronic Nitrogen Addition plots at the Harvard Forest, Petersham MA, beginning in November 1988. Plots received nitrogen additions of 0, 5 and 15 g N m-2yr-1 in two different stand types: red pine and mixed hardwood. Bags were collected in August and November of each year and litter analysed for mass remaining, nitrogen, cellulose and lignin content. Mass remaining was significantly greater for litter in nitrogen treated plots than in control plots after 48 months. Lignin content of litter was significantly higher with nitrogen treatments but there was little effect of treatment on cellulose content. N concentration was similar between treatments, but greater mass remaining in treated plots resulted in a higher total amount of N in humus produced in the high N plot. This mechanism could be a sink for up to 1.5 g N·m-2yr-1 of the 1.5 g N·m-2yr-1 added annually to the high N plots. Reduced decomposition rates in conjunction with increased lignin accumulation could impact global carbon sequestration as well.
