An Ardent Flame: Witness to Distant Suffering, Human Rights and Unworthy Victims in the Coverage by The New York Times and Two Journals of the Religious Left of the 1980s Civil Wars in El Salvador and Nicaragua

Scholars have investigated witness to distant suffering (WTDS) almost entirely in visual media. This study examines it in print. This form of reporting will be examined in two publications of the religious left as contrasted with the New York Times. The thesis is that, more than any technology, WTDS consists of the journalist’s moral commitment and narrative skills and the audience’s analytical resources and trust. In the religious journals, liberation theology provides the moral commitment, the writers and editors the narrative skills and trust and the special vision of the newly empowered poor the analytical foundation. In bearing witness to those who have suffered state or guerilla terrorism in El Salvador and Nicaragua during the 1980s, we will investigate a distinction between “worthy” and “unworthy victims.” This last issue has a special ethical and political significance. Media witnessing to the suffering of strangers can help them become known, and so “worthy.” It can help them, and their plight and cause, become better recognized. This is the power of the media.

Annulation of Tetrathiafulvalene to the Bay Region of Perylenediimide: Fast Electron-Transfer Processes in Polar and Nonpolar Solvents

A tetrathiafulvalene donor has been annulated to the bay region of perylenediimide through a 1H-benzo-[d]pyrrolo[1,2-a]imidazol-1-one spacer affording an extended pi-conjugated molecular dyad (TTF-PDI). To gain insight into its ground- and excited-state electronic properties, the reference compound Ph-PDI has been prepared via a direct Schiff-base condensation of N,N'-bis(1-octylnonyl) benzoperylene-1',2':3,4:9,10-hexacarboxylic-1',2'-anhydride-3,4:9,10-bis (imide) with benzene-1,2-diamine. Both the experimental and the computational (DFT) results indicate that TTF-PDI exhibits significant intramolecular electronic interactions giving rise to an efficient photoinduced charge-separation process. Free-energy calculations verify that the process from TTF to the singlet-excited state of PDI is exothermic in both polar and nonpolar solvents. Fast adiabatic electron-transfer processes of a compactly fused, pi-conjugated TTF-PDI dyad in benzonitrile, 2-methyltetrahydrofuran, anisole and toluene were observed by femtosecond transient absorption spectral measurements. The lifetimes of radical-ion pairs slightly increase with decreasing the solvent polarities, suggesting that the charge-recombination occurs in the Marcus inverted region. By utilizing the nanosecond transient absorption technique, the intermolecular electron-transfer process in a mixture of has been observed via the triplet excited PDI for the first time.

DEVELOPMENT OF A CONCEPTUAL MODEL AND PARAMETERIZATION OF A MATHEMATICAL MODEL FOR SEDIMENT PHOSPHORUS DIAGENESIS, SORPTION AND RELEASE FROM ONONDAGA LAKE SYRACUSE, NEW YORK

Eutrophication is a persistent problem in many fresh water lakes. Delay in lake recovery following reductions in external loading of phosphorus, the limiting nutrient in fresh water ecosystems, is often observed. Models have been created to assist with lake remediation efforts, however, the application of management tools to sediment diagenesis is often neglected due to conceptual and mathematical complexity. SED2K (Chapra et al. 2012) is proposed as a "middle way", offering engineering rigor while being accessible to users. An objective of this research is to further support the development and application SED2K for sediment phosphorus diagenesis and release to the water column of Onondaga Lake. Application of SED2K has been made to eutrophic Lake Alice in Minnesota. The more homogenous sediment characteristics of Lake Alice, compared with the industrially polluted sediment layers of Onondaga Lake, allowed for an invariant rate coefficient to be applied to describe first order decay kinetics of phosphorus. When a similar approach was attempted on Onondaga Lake an invariant rate coefficient failed to simulate the sediment phosphorus profile. Therefore, labile P was accounted for by progressive preservation after burial and a rate coefficient which gradual decreased with depth was applied. In this study, profile sediment samples were chemically extracted into five operationally-defined fractions: CaCO3-P, Fe/Al-P, Biogenic-P, Ca Mineral-P and Residual-P. Chemical fractionation data, from this study, showed that preservation is not the only mechanism by which phosphorus may be maintained in a non-reactive state in the profile. Sorption has been shown to contribute substantially to P burial within the profile. A new kinetic approach involving partitioning of P into process based fractions is applied here. Results from this approach indicate that labile P (Ca Mineral and Organic P) is contributing to internal P loading to Onondaga Lake, through diagenesis and diffusion to the water column, while the sorbed P fraction (Fe/Al-P and CaCO3-P) is remaining consistent. Sediment profile concentrations of labile and total phosphorus at time of deposition were also modeled and compared with current labile and total phosphorus, to quantify the extent to which remaining phosphorus which will continue to contribute to internal P loading and influence the trophic status of Onondaga Lake. Results presented here also allowed for estimation of the depth of the active sediment layer and the attendant response time as well as the sediment burden of labile P and associated efflux.

New Sites, New Challenges? Ethical and Methodological Questions in the Context of Research on Migration Exclusion

The challenges of research ethics and methodologies have been reflected on extensively, but – aside from the context of feminist methodologies – less so in relation to research on particular migration sites such as in transit, detention centres, at the borders or within migration administration. First attempts in this direction have been made (Düvell et al. 2010, Fresia et al. 2005, Riedner 2014, van Liempt/Bilger2009), however, more reflection and theorization is needed, considering the contested nature of these temporal and volatile sites. In this workshop, we thus aim at examining methodological as well as ethical questions that arise during field work: We attempt to reflect the power relations involved in the research process, the ethics of research design, the dissemination of research results, the question of gaining access to and – whenever necessary – staying in contact with our research subjects. How can we negotiate informed consent with subjects whose life is currently marked by transit and insecurity concerning their own future, and who are in an uncertain situation in which substantial information (legal, social, cultural etc.) is likely to be missing? How do we deal with the dilemma of possibly contributing to knowledge production that might facilitate removals and deportations in the future, considering that the reception of the results is not in the hands of the researchers? How do we deal with the anticipated as well as unexpected impacts of our research on social and political practice? Regarding fieldwork in state institutions, how do we negotiate the multiple loyalties we often find ourselves faced with as social researchers, both with the excluded migrants and with the authorities implementing the exclusions – two groupings considered to be opposite to each other (Lavanchy 2013)? Which different roles do researchers need to take on? The aim of our workshop is first and foremost to exchange experiences on fieldwork with others doing qualitative research on related topics and to consider its possible implications – including affective dimensions – for all participants involved in the research process: the migrants, the security staff of detention centres, its social workers, border police and bureaucrats and, last but not least, the researchers themselves. Furthermore, we generally wish to reflect upon the question of how best to conduct research in this contested field, applying an interdisciplinary perspective.

Age models of ODP sites from the Barents Sea-Svalbard region

Based on a revised chronostratigraphy, and compilation of borehole data from the Barents Sea continental margin, a coherent glaciation model is proposed for the Barents Sea ice sheet over the past 3.5 million years (Ma). Three phases of ice growth are suggested: (1) The initial build-up phase, covering mountainous regions and reaching the coastline/shelf edge in the northern Barents Sea during short-term glacial intensification, is concomitant with the onset of the Northern Hemisphere Glaciation (3.6-2.4 Ma). (2) A transitional growth phase (2.4-1.0 Ma), during which the ice sheet expanded towards the southern Barents Sea and reached the northwestern Kara Sea. This is inferred from step-wise decrease of Siberian river-supplied smectite-rich sediments, likely caused by ice sheet blockade and possibly reduced sea ice formation in the Kara Sea as well as glacigenic wedge growth along the northwestern Barents Sea margin hampering entrainment and transport of sea ice sediments to the Arctic-Atlantic gateway. (3) Finally, large-scale glaciation in the Barents Sea occurred after 1 Ma with repeated advances to the shelf edge. The timing is inferred from ice grounding on the Yermak Plateau at about 0.95 Ma, and higher frequencies of gravity-driven mass movements along the western Barents Sea margin associated with expansive glacial growth.
