Seeking goals in the urban estuary : how a personal migrant subjectivity is reified into productive strategies and generative social effects.
Using a micro-level frame of analysis, and working from in-depth interviews in Johannesburg's migrant-rich ‘urban estuaries,’ this research report considers participants’ personal, subjective, understanding of their own migrant-ness. The paper argues that theirs is a migrant subjectivity linked to the praxis of goal seeking, rather than the achievement of belonging. The goal seeking subjectivity is reified into pragmatic social strategies of network building, trust, and opportunity creation that undermine the concepts of generalized trust, communal social capital, and the host/migrant dichotomy. Personal subjectivies are rendered social. Denizens fill the social space with presentations and assessments of ‘mutual beneficence,’ and seek out demographically ambivalent networks of commonality
Eleven Antitheses on Cities and States: Challenging the Mindscape of Chronology and Chorography in Anthropogenic Climate Change
Our basic argument is that we should be thinking in trans-modern ways when considering how to react to anthropogenic climate change. Showing that mainstream approaches to climate change theory and policymaking are overtly modern, we identify this as a mindscape inherently constrained by its particular chronology and chorography. Our contribution to necessary trans-modern thinking is a presentation of eleven basic and widely accepted theses on modern chronology and chorography that we contest through antitheses, which we argue are more suited to engaging with anthropogenic climate change. These support a consumption argument for urban demand being the crucial generator of climate for 8,000 years in direct contradiction to the production argument that greenhouse gases are the crucial generator of climate change for 200 years. The modern policymaking focus on curbing carbon emissions is thus fundamentally flawed - merely feeding energy for continuing an accelerating global consumption in a different way that is only marginally more climate-friendly. Reflecting on the antitheses, we conclude by discussing the difficulties of translating trans-modern ideas into political action
Bis(2-acetylpyridine-κ2 N,O)silver(I) tetrafluoridoborate: a complex with silver in a seesaw coordination geometry
The reaction of 2-acetylpyridine with silver(I) tetrafluoridoborate leads to the discrete title complex, [Ag(C7H7NO)2]BF4, in the cation of which the Ag atom is coordinated by two 2-acetylpyridine ligands, each of which is N,O-bidentate, albeit with stronger bonding to the N atoms [Ag—N = 2.2018 (15) and 2.2088 (14) Å; Ag—O = 2.5380 (13) and 2.5454 (13) Å]. The four-coordinate Ag atom has a seesaw coordination geometry with a τ4 index of 0.51. The tetrafluoridoborate anion is disordered over two orientations with 0.568 (10):0.432 (10) occupancies

Therapists' techniques in the treatment of adolescent depression
When comparing the relative effectiveness of different psychological treatment approaches using clinical trials, it is essential to establish fidelity to each manualized therapy, and differentiation between the treatment arms. Yet few psychological therapy trials include details about the assessment of treatment integrity and little is known about the specific techniques used by therapists, or to what degree these techniques are shared or distinct across different therapeutic approaches. The aims of this study were to (a) establish the fidelity of two established psychological therapies, cognitive- behavior therapy (CBT) and short-term psychoanalytic psychotherapy (STPP), in the treatment of adolescent depression; and (b) examine whether they were delivered with adherence to their respective treatment modalities, and if they could be differentiated from each other and from a reference treatment (a brief psychosocial intervention; BPI). The study also aimed to identify shared and distinct techniques used within and across the three treatments. Audiotapes (N = 230) of therapy sessions collected as part of a trial were blind double-rated using the Comparative Psychotherapy Process Scale (Hilsenroth, Ackerman, Blagys, Baity, & Mooney, 2003; Hilsenroth, Defife, Blake, & Cromer, 2007), which includes subscales for Cognitive-Behavioral and Psychodynamic- Interpersonal techniques. The treatments were delivered with reasonable fidelity and there was clear differentiation in the use of CBT and STPP, and between these two established psychological therapies and BPI. An item-level analysis identified techniques used across all three treatments, techniques that were shared between BPI and CBT, and techniques that were unique to CBT and STPP
Oligosaccharide and Glycoprotein Microarrays as Tools in HIV Glycobiology Glycan-Dependent gp120/Protein Interactions
AbstractDefining HIV envelope glycoprotein interactions with host factors or binding partners advances our understanding of the infectious process and provides a basis for the design of vaccines and agents that interfere with HIV entry. Here we employ carbohydrate and glycoprotein microarrays to analyze glycan-dependent gp120-protein interactions. In concert with new linking chemistries and synthetic methods, the carbohydrate arrays combine the advantages of microarray technology with the flexibility and precision afforded by organic synthesis. With these microarrays, we individually and competitively determined the binding profiles of five gp120 binding proteins, established the carbohydrate structural requirements for these interactions, and identified a potential strategy for HIV vaccine development
catena-Poly[[silver(I)-μ-4-aminopyridine] perchlorate]: a 1-D staircase coordination polymer
Reaction of 4-aminopyridine with silver(I) perchlorate leads to a one-dimensional coordination polymer, {[Ag(C5H6N2)]ClO4}n, in which the aminopyridine binds through both N atoms. The perchlorate anion is hydrogen bonded to the amino H atoms and interacts weakly with the silver(I) atoms (Ag—O > 2.70 Å), both located on inversion centres, and some aromatic H atoms (O—H > 2.55 ÅA), thereby extending the dimensionality of the assembly. This is the first silver complex in which this ligand acts in a bridging mode
