Bringing Development Back into (Economic) Sociology: Andrew Schrank Interviewed by Felipe GonzĂĄlez and Aldo Madariaga
Andrew Schrank (Olive C. Watson Professor of Sociology and International and Public Affairs at Brown University) is one of the few academics with a true interdisciplinary trajectory and an exceptionally wide variety of interests in economic sociology and adjacent fields working on Latin America. Although he defines himself as an organizational sociologist, Andrew has held positions in both sociology and political science departments and has written about issues ranging from supply chains to foreign investment and labor standards, from healthcare to industrial policy and urban studies, and from varieties of capitalism to the role of culture in development, doing both broad comparative work and more focused case studies of small Mesoamerican countries like the Dominican Republic. Andrew co-authored the article that became the manifesto for the re-foundation of Latin Americaâs political economy tradition in what is now the Red EconomĂa PolĂtica America Latina (REPAL) and is currently working on a book on economic sociology and development. Andrew agreed to talk about his views on the discipline, the challenges of interdisciplinarity, and his focus on Latin America. This is the result of a deeply engaged discussion over a Skype conversation and several e-mail exchanges where he calls for a return to sociologyâs early motivation of studying societies through the lens of development and claims that âwhat we need is an economic sociology that takes Latin America seriously.â We thank Andrew for his generosity in sharing his thoughts with us
Mycoplasma hyopneumoniae Transcription Unit Organization: Genome Survey and Prediction
Mycoplasma hyopneumoniae is associated with swine respiratory diseases. Although gene organization and regulation are well known in many prokaryotic organisms, knowledge on mycoplasma is limited. This study performed a comparative analysis of three strains of M. hyopneumoniae (7448, J and 232), with a focus on genome organization and gene comparison for open read frame (ORF) cluster (OC) identification. An in silico analysis of gene organization demonstrated 117 OCs and 34 single ORFs in M. hyopneumoniae 7448 and J, while 116 OCs and 36 single ORFs were identified in M. hyopneumoniae 232. Genomic comparison revealed high synteny and conservation of gene order between the OCs defined for 7448 and J strains as well as for 7448 and 232 strains. Twenty-one OCs were chosen and experimentally confirmed by reverse transcriptionâPCR from M. hyopneumoniae 7448 genome, validating our prediction. A subset of the ORFs within an OC could be independently transcribed due to the presence of internal promoters. Our results suggest that transcription occurs in ârun-onâ from an upstream promoter in M. hyopneumoniae, thus forming large ORF clusters (from 2 to 29 ORFs in the same orientation) and indicating a complex transcriptional organization

Characterization of the KATRIN cryogenic pumping section
The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to determine the effective anti-electron neutrino mass with a sensitivity of 0.2 eV/c by using the kinematics of tritium -decay. It is crucial to have a high signal rate which is achieved by a windowless gaseous tritium source producing 10 -electrons per second. These are guided adiabatically to the spectrometer section where their energy is analyzed. In order to maintain a low background rate below 0.01 cps, one essential criteria is to permanently reduce the flow of neutral tritium molecules between the source and the spectrometer section by at least 14 orders of magnitude. A differential pumping section downstream from the source reduces the tritium flow by seven orders of magnitude, while at least another factor of 10 is achieved by the cryogenic pumping section where tritium molecules are adsorbed on an approximately 3 K cold argon frost layer. In this paper, the results of the cryogenic pumping section commissioning measurements using deuterium are discussed. The cryogenic pumping section surpasses the requirement for the flow reduction of 10 by more than one order of magnitude. These results verify the predictions of previously published simulations
WELLFOCUS PPT â modified positive psychotherapy to improve well-being in psychosis: study protocol for a pilot randomised controlled trial
BACKGROUND: The promotion of well-being is an important goal of recovery oriented mental health services. No structured, evidence-based intervention exists that aims to increase the well-being in people with severe mental illness such as psychosis. Positive psychotherapy (PPT) is a promising intervention for this goal. Standard PPT was adapted for use with people with psychosis in the UK following the Medical Research Council framework for developing and testing complex interventions, resulting in the WELLFOCUS Model describing the intended impact of WELLFOCUS PPT. This study aims to test the WELLFOCUS Model, by piloting the intervention, trial processes, and evaluation strategy. METHODS/DESIGN: This study is a non-blinded pragmatic pilot RCT comparing WELLFOCUS PPT provided as an 11-session group therapy in addition to treatment as usual to treatment as usual alone. Inclusion criteria are adults (aged 18â65 years) with a main diagnosis of psychosis who use mental health services. A target sample of 80 service users with psychosis are recruited from mental health services across the South London and Maudsley NHS Foundation Trust. Participants are randomised in blocks to the intervention and control group. WELLFOCUS PPT is provided to groups by specifically trained and supervised local therapists and members of the research team. Assessments are conducted before randomisation and after the group intervention. The primary outcome measure is well-being assessed by the Warwick-Edinburgh Mental Well-being Scale. Secondary outcomes include good feelings, symptom relief, connectedness, hope, self-worth, empowerment, and meaning. Process evaluation using data collected during the group intervention, post-intervention individual interviews and focus groups with participants, and interviews with trial therapists will complement quantitative outcome data. DISCUSSION: This study will provide data on the feasibility of the intervention and identify necessary adaptations. It will allow optimisation of trial processes and inform the evaluation strategy, including sample size calculation, for a future definitive RCT. TRIAL REGISTRATION: Current Controlled Trials ISRCTN04199273 â WELLFOCUS study: an intervention to improve well-being in people with psychosis, Date registered: 27 March 2013, first participant randomised on 26 April 2013
Disentangling nature from nurture in examining the interplay between parentâchild relationships, ADHD, and early academic attainment
Background: Attention Deficit Hyperactivity Disorder (ADHD) is highly heritable and is associated with lower educational attainment. ADHD is linked to family adversity, including hostile parenting. Questions remain regarding the role of genetic and environmental factors underlying processes through which ADHD symptoms develop and influence academic attainment.
Method: This study employed a parent-offspring adoption design (N=345) to examine the interplay between genetic susceptibility to child attention problems (birth mother ADHD symptoms) and adoptive parent (mother and father) hostility on child lower academic outcomes, via child ADHD symptoms. Questionnaires assessed birth mother ADHD symptoms, adoptive parent (mother and father) hostility to child, early child impulsivity/activation, and child ADHD symptoms. The Woodcock-Johnson test was used to examine child reading and math aptitude.
Results: Building on a previous study (Harold et al., 2013), heritable influences were found: birth mother ADHD symptoms predicted child impulsivity/activation. In turn, child impulsivity/activation (4.5 years) evoked maternal and paternal hostility, which was associated with childrenâs ADHD continuity (6 years). Both maternal and paternal hostility (4.5 years) contributed to impairments in math but not reading (7 years), via impacts on ADHD symptoms (6 years).
Conclusion: Findings highlight the importance of early child behavior dysregulation evoking parent hostility in both mothers and fathers, with maternal and paternal hostility contributing to the continuation of ADHD symptoms and lower levels of later math ability. Early interventions may be important for the promotion of child math skills in those with ADHD symptoms, especially where children have high levels of early behavior dysregulation
