Resituating Reciprocity within Longer Legacies of Colonization: A Conversation

his conversation/article resituates the concept of reciprocity, as it has been theorized and enacted in rhetoric, composition, and literacy studies, within a larger framework of social justice, one that recognizes legacies of struggle, survival and perseverance. When situated within the Filipinx indigenous notion of kapwa, reciprocity takes a temporal turn not only in recognizing that building trust and reciprocity happen repeatedly over time but also in recognizing how enacting reciprocity extends beyond initial research contexts, participants, and outcomes. Enacting reciprocity requires slowing down in time and working with others in social justice work strategically, tactically, and repeatedly over longer durations. To see ourselves as reciprocal beings means that we continually see ourselves as members of a larger community invested in making structural asymmetries legible and open to deep revision

Complexes formed by zinc and cyanide ions at elevated pH.

Thesis (M.Sc.)-University of Natal, Durban, 1990.The experimental work described in this thesis is aimed primarily towards elucidation of the speciation of zinc-cyanide systems at elevated pH. In this study the formation and stability of H+-eN-, binary Zn2+-eN- and ternary Zn2+-CN--QH- complexes were studied by glass electrode potentiometry in aqueous solutions at 25.0°0 and in a medium of ionic strength of 0.1 mol dm-3. The solution pH was varied to cover the range 4 to 11. The study was undertaken with a view to establishing whether and under what conditions soluble binary zinc-cyanide complexes and ternary zinc-cyanide-hydroxide complexes form, and to determine formation constants for any such species that are found. This information would be useful in defining more precisely the speciation of solutions containing zinc and cyanide ions at elevated pH values. A titration method was used, in which hydrogen ion concentration was monitored by means of a glass indicating electrode. The cell was calibrated to allow measurements of hydrogen ion concentration rather than hydrogen ion activity. Owing to precipitation difficulties, the reagents were used at sub-millimolar concentration levels. The potentiometric data was interpreted with the aid of various formation function plots together with the use of various computer programs, such as HALTAFALL and ESTA. The results show that the ternary complex Zn(ON)3(OH)2- is formed in significant amounts in solutions of pH > 8.5. Some evidence was also obtained for the existence of the five coordinated species Zn(CN)3(OH)~- and Zn(CN)~- in these solutions, but existence of the latter two species cannot yet be regarded as firmly established. No polynuclear complexes were detected at the sub-millimolar concentrations used. Formation constants are reported for H+-eN- and both binary Zn2+-eN- and ternary Zn2+-eN--QH- species

Maison Drucker og ”La chaise de bistrot parisienne”

Den franske virksomhed Maison Drucker blev etableret i Paris i 1885 af den 21- årige polske immigrant Louis Drucker, der ville producere håndlavede rattan-stole til overklassens samtale- og rygerum samt til caféer, hoteller og kasinoer. Denne opgave analyserer Maison Drucker og deres stol ”La chaise de bistrot parisienne” i en designkulturel optik med henblik på at forstå, hvordan man kan tale om, at virksomheden har genvundet positionering på nutidens konkurrenceprægede marked. Opgaven vil således belyse Maison Druckers branding og undersøge, hvorledes man kan tale om, at de herved har forsøgt at skabe en forbrugskulturel betydning omkring deres stol, som forbrugere kan definere sig gennem

Triplet exciton percolation and superexchange: Naphthalene C10H8–C10D8

The phosphorescence of betamethylnaphthalene doped into a naphthalene−h8/naphthalene−d8 mixed crystal has been measured. The results demonstrate that (1) dynamical exciton percolation does occur (i.e., a transition from an exciton insulator to an exciton conductor), that (2) it is very useful for the investigation of energy transfer in molecular aggregates, and that (3) it is a critical test of our current knowledge of exciton exchange and superexchange.
