This paper explores alterations in social dynamics caused by coca crops in Curvaradó and Jiguamiandó, at Choco department in the Colombian Pacific region. The research analyzes the role of armed actors such as paramilitaries and guerrillas in the conformation of new social spaces where local people find resistance as the main tool to survive in chaotic environments. Local power as a politics of resistance is also analyzed. Non-governmental organizations are a key tool to comprehend new social configurations. By doing the analysis and comparison using political ecology as the theoretical background along with concepts of moral economy and everyday resistance, with qualitative research methods. The paper aims to interpret and provide a better understanding of those changes considering social-environmental relations. Findings suggest that those changes in social structure are leading to an understanding, not just of the organization of the area, but also that social dynamics and coca crops cannot be generalized in the country.

Background/Aims: Insulin resistance and systemic hypertension are predictors of advanced fibrosis in obese patients with non-alcoholic fatty liver disease (NAFLD). Genetic factors may also be important. We hypothesize that high angiotensinogen (AT) and transforming growth factor-beta1 (TGF-beta1) producing genotypes increase the risk of liver fibrosis in obese subjects with NAFLD. Methods: One hundred and five of 130 consecutive severely obese patients having a liver biopsy at the time of laparoscopic obesity surgery agreed to have genotype analysis. Influence of specific genotype or combination of genotypes on the stage of hepatic fibrosis was assessed after controlling for known risk factors. Results: There was no fibrosis in 70 (67%), stages 1-2 in 21 (20%) and stages 3-4 fibrosis in 14 (13%) of subjects. There was no relationship between either high AT or TGF-beta1 producing genotypes alone and hepatic fibrosis after controlling for confounding factors. However, advanced hepatic fibrosis occurred in five of 13 subjects (odds ratio 5.7, 95% confidence interval 1.5-21.2, P = 0.005) who inherited both high AT and TGF-beta1 producing polymorphisms. Conclusions: The combination of high AT and TGF-beta1 producing polymorphisms is associated with advanced hepatic fibrosis in obese patients with NAFLD. These findings support the hypothesis that angiotensin II stimulated TGF-beta1 production may promote hepatic fibrosis. (C) 2003 European Association for the Study of the Liver.

The rise of the knowledge economy brings to the foreground questions of how firms might best capture the value of their intellectual assets. In this article I introduce the notion of strategic interventions in intellectual asset flows designed to influence the level and composition of intellectual asset scarcity, with implications for firm performance. I also present propositions that explain and predict how contingencies at differing levels of analysis influence the choice of strategic intervention.

Two new antibacterial agents, rugulotrosin A (1) and B (2), were obtained from cultures of a Penicillium sp. isolated from soil samples acquired near Sussex Inlet, New South Wales, Australia. Rugulotrosin A (1) is a chiral symmetric dimer, and its relative stereostructure was determined by spectroscopic and X-ray crystallographic analysis. Rugulotrosin B (2) is a chiral asymmetric dimer isomeric with 1. Its structure was determined by spectroscopic analysis with comparison to the co-metabolite 1 and previously reported fungal metabolites. Both rugulotrosins A and B displayed significant antibacterial activity against Bacillus subtilis, while rugulotrosin A was also strongly active against Enterococcus faecalis and B. cereus.

Background The risk of adverse pregnancy outcome for women with type 1 diabetes is reduced through tight diabetes control. Most women enter pregnancy with inadequate blood glucose control. Interview studies with women suggest the concept of ‘planned’ and ‘unplanned’ pregnancies is unhelpful. Aim To explore women's accounts of their journeys to becoming pregnant while living with type 1 diabetes. Design of study Semi-structured interviews with 15 women living with pre-gestational type 1 diabetes, between 20 and 30 weeks gestation and with a normal pregnancy ultrasound scan. Setting Four UK specialist diabetes antenatal clinics. Method Interviews explored women's journeys to becoming pregnant and the impact of health care. Analysis involved comparison of women's accounts of each pregnancy and a thematic analysis. Results Women's experiences of becoming pregnant were diverse. Of the 40 pregnancies described, at least one positive step towards becoming pregnant was taken by 11 women in 23 pregnancies but not in the remaining 17 pregnancies, with variation between pregnancies. Prior to and in early pregnancy, some women described themselves as experts in their diabetes but most described seeking and/or receiving advice from their usual health professionals. Three women described pre-conception counselling and the anxiety this provoked. Conclusion For women living with type 1 diabetes each pregnancy is different. The concept of planned and unplanned pregnancy is unhelpful for designing health care. Formal preconception counselling can have unintended consequences. Those providing usual care to women are well positioned to provide advice and support to women about becoming pregnant, tailoring it to the changing needs and situation of each woman.

Purpose: To compare distance and near visual performance with a zero-aberration aspheric intraocular lens (IOL) (Softec HD, Lenstec, Inc. FL, USA) with that of an otherwise identical, but spherical IOL (Softec 1). Setting: Department of Ophthalmology, Solihull Hospital, West Midlands, United Kingdom. Methods: This prospective study comprised 37 patients with a Softec 1 spherical IOL implanted in one eye, who underwent phacoemulsification and received the Softec HD aspheric IOL in the fellow eye. One month post-operatively, unaided distance and near vision, residual refraction, best spectacle corrected distance and near visual acuity, reading speed, pseudoaccommodation and photopic contrast sensitivity were recorded. Wavefront analysis enabled comparison of higher order aberrations between the IOLs. Results: Prior to surgery, the Softec 1 and Softec HD eyes were not significantly different. Post-operatively, unaided vision, best spectacle corrected visual acuity and residual refraction were not significantly different between the eyes, nor were there significant differences observed between the measured wavefront aberrations. Once implanted, the range of focus was significantly better in the Softec HD IOL eye than the Softec 1 IOL eye and, although reading speed was equivalent to the Softec 1 eye, the print size at which this could be achieved was significantly smaller. Conclusions: Depth of field was significantly improved with the aspheric IOL compared with the spherical IOL, without any compromise in distance visual performance between the two IOLs.

New regionalism and globalization have been prominent themes in academic and political debates since the beginning of the 1990s. Despite the considerable amount of scholarly attention that the new regionalism has received in recent years, its full empirical and theoretical potential has yet to be fully investigated. This illuminating study provides an overview of new avenues in theorizing regionalism and proposes a consolidated framework for analysis and comparison. Offering a comparative historical perspective of European and Southeast Asian regionalism, it presents new and imaginative insights into the theory and practice of regionalism and the links between regional developments, globalization and international order. Contents: Introduction; Regionalism and integration theory the first wave: traditional approaches; New regionalism the second wave: towards a framework for comparative regionalism; Regionalism in the EU and ASEAN during the Cold War: the first wave; Second-wave regionalism: the post-Cold War period; Identifying regions: emerging regional identities in Europe and East Asia; Conclusion; Appendix; Bibliography; Index.

In this paper a Hierarchical Analytical Network Process (HANP) model is demonstrated for evaluating alternative technologies for generating electricity from MSW in India. The technological alternatives and evaluation criteria for the HANP study are characterised by reviewing the literature and consulting experts in the field of waste management. Technologies reviewed in the context of India include landfill, anaerobic digestion, incineration, pelletisation and gasification. To investigate the sensitivity of the result, we examine variations in expert opinions and carry out an Analytical Hierarchy Process (AHP) analysis for comparison. We find that anaerobic digestion is the preferred technology for generating electricity from MSW in India. Gasification is indicated as the preferred technology in an AHP model due to the exclusion of criteria dependencies and in an HANP analysis when placing a high priority on net output and retention time. We conclude that HANP successfully provides a structured framework for recommending which technologies to pursue in India, and the adoption of such tools is critical at a time when key investments in infrastructure are being made. Therefore the presented methodology is thought to have a wider potential for investors, policy makers, researchers and plant developers in India and elsewhere. © 2013 Elsevier Ltd.

This study examines changes in the Cuban family in the United States produced by time, migration, and the rise of new generations. The thesis will use a data set extracted from the 5% Public Use Microdata Series (PUMS) of the U.S. Decennial Census of Population for the years 1970, 1980 and 1990. Contingency table analysis and comparison of means were used to examine various family-related variables. The analysis points to changes in the traditional Cuban family towards less traditional family arrangements. The multigenerational feature of the Cuban household has diminished as the elderly have become independent and are more likely to be living on their own. Although female labor participation remains high, the occupational patterns of the first generation of Cuban women have diversified and a new trend has emerged for the second generation. The second generation of Cuban women demonstrates a strong inclination for white-collar occupations. Fertility rates remain low.

This research has as a central point of discussion the relationship between the action and the stage lighting, directed to scenes in which, from the exchange between actor and professional lighting, you can develop comic situations. The particularity of these scenes is the involvement of lighting as presentification feature a character in the scene, made possible by game created with the actor. In order to develop this discussion, the author divides the text into three chapters, the first being a memorial of his artistic career and his creative processes, enabling the reader to situate the paths taken by the author for the study. Then discusses possible relationship between performance and lighting, pointing situations where the two are directly related. Finally, an analysis and comparison of two comic scenes in which the actor play with the lighting suggests a character through presentification lighting on the scene. Leads the discussion to the conclusion, proposing the term light-character to set the lighting feature, suggesting characters in the scene.

This dissertation uncovers and analyzes the complicated history of the devil’s pact in literature from approximately 1330 to 2015, focusing primarily on texts written in German and Dutch. That the tale of the pact with the devil (the so-called Faustian bargain) is one of the most durable and pliable literary themes is undeniable. Yet for too long, the success of Johann Wolfgang von Goethe’s Faust I (1808) decisively shaped scholarship on early devil’s pact tales, leading to a misreading of the texts with Goethe’s concerns being projected onto the earliest manifestations. But Goethe’s Faust really only borrows from the original Faust his name; the two characters could not be more different. Furthermore, Faustus was not the only early pact-maker character and his tale was neither limited to the German language nor to the Protestant faith. Among others, tales written in Dutch about a female, Catholic, latemedieval pact-maker, Mariken van Nieumeghen (1515), illustrate this. This dissertation seeks to redeem the early modern Faustus texts from its misreading and to broaden the scholarship on the literature of the devil’s pact by considering the Mariken and Faust traditions together.

The first chapter outlines the beginnings of pact literature as a Catholic phenomenon, considering the tales of Theophilus and Pope Joan alongside Mariken of Nijmegen. The second chapter turns to the original Faust tale, the Historia von D. Johann Fausten (1587), best read as a Lutheran response to the Catholic pact literature in the wake of the Reformation. In the third chapter, this dissertation offers a new, united reading of the early modern Faust tradition. The fourth and fifth chapters trace the literary preoccupation with the pacts of both Mariken and Faustus from the late early modern to the present.

The dissertation traces the evolution of these two bodies of literature and provides an in-depth analysis and comparison of the two that has not been done before. It argues for a more global literary scholarship that considers texts across multiple languages and one that takes into consideration the rich body of material of the pact tradition.

Objective: Identify preventive self-care practices and analyze the configurations of the network support for women with and without breast cancer registered in a mammography-monitoring project from Porto Alegre/Brazil.Method: a mixed sequential delimitation was performed, which expanded the results of the quantitative step (cross and correlation section) in a qualitative step (narrative interviews). 37 women diagnosed with breast cancer (group 1) and 72 without this diagnosis (group 2 – monitoring) participated. The following instruments were used: Assessment Questionnaire Self-care Ability (ASA-A) and Assessment Questionnaire Perceived Social Support and Community. There were performed descriptive analysis and comparison of means (t test and ANOVA) between the two groups. To deepen the understanding of the data, we selected four women with breast cancer with extreme levels on the scale of Social Support to participate in the biographical narrative interviews.Results: the analysis indicate that women who had breast cancer have better self-care practices than the women from the monitoring project (t = 1.791, P = 0.027). As for the analysis of social support, there were no statistically significant differences between the two groups. All participants have an average level of perceived social and community support. It was highlighted by the qualitative data that it was after the diagnosis of breast cancer that women lived self-care aspects they had not previously experienced.Conclusions: the self-care was significantly bigger in the group of women with breast cancer, where the cancer diagnosis was a trigger to increase self-care.

OBJETIVO: avaliar a sintomatologia climatérica e fatores relacionados entre mulheres dos meios urbano e rural do Rio Grande do Norte. MÉTODOS: estudo transversal, descritivo, envolvendo casuística de 261 mulheres climatéricas residentes em Natal e Mossoró (grupo urbano; n=130) e Uruaçu, em São Gonçalo do Amarante (grupo rural; n=131). A sintomatologia climatérica foi avaliada pelo Índice Menopausal de Blatt-Kupperman (IMBK) e Escala Climatérica de Greene (ECG). A análise estatística constou de comparações das medianas dos escores entre os grupos e regressão logística. Defi niram-se como “muito sintomáticas” as pacientes com escores ≥20, para ambos instrumentos (variável dependente). As variáveis independentes foram: idade, procedência, alfabetização, obesidade e prática de atividade física. RESULTADOS: o grupo urbano apresentou escores signifi cativamente superiores ao grupo rural, tanto para o IMBK (medianas de 26,0 e 17,0, respectivamente; p<0,0001), quanto para a ECG (medianas de 27,0 e 16,0, respectivamente; p<0,0001). Na amostra total, evidenciou-se que 56,3% (n=147) das mulheres foram classifi cadas como “muito sintomáticas”. Na comparação intergrupos, essa prevalência foi signifi cativamente mais elevada nas mulheres urbanas em relação às rurais (79,2 e 33,6%, respectivamente; p<0,05). Pela análise de regressão logística, evidenciou-se que a chance de pertencer ao grupo defi nido como “muito sintomáticas” foi maior para mulheres do meio urbano [odds ratio ajustado (OR)=7,1; 95% intervalo de confi ança a 95% (IC95%)=3,69-13,66] e alfabetizadas (OR=2,19; IC95%=1,16-4,13). A idade superior a 60 anos associou-se com menor chance de ocorrência de sintomas signifi cativos (OR=0,38; IC95%=0,17-0,87). CONCLUSÕES: a prevalência de sintomas climatéricos signifi cativos é menor em mulheres do meio rural, demonstrando que fatores socioculturais e ambientais estão fortemente relacionados ao surgimento dos sintomas climatéricos em nossa população.___________________________________ABSTRACT PURPOSE: to evaluate climacteric symptoms and related factors in women living in rural and urban areas of Rio Grande do Norte, Brazil. METHODS: a cross-sectional study involving 261 women in the climacteric was performed. A total of 130 women from Natal and Mossoró (urban group) and 131 from Uruaçu, in São Gonçalo do Amarante (rural group), were studied. Climacteric symptoms were assessed by the Blatt-Kupperman Menopausal Index (BKMI) and Greene Climacteric Scale (GCE). Statistical analysis involved comparison of median between groups and logistic regression analysis. Patients were defi ned as “very symptomatic” when the climacteric score was ≥20 for both questionnaires (dependent variable). Independent variables were: age, living area, schooling, obesity and physical activity. RESULTS: the urban group had signifi cantly higher scores than those of the rural group, both for BKMI (median of 26.0 and 17.0, respectively; p<0.0001) and for GCE (median of 27.0 and 16.0, respectively; p<0.0001). For the entire sample, a total of 56.3% (n=147) of the women were classifi ed as “very symptomatic”. This prevalence was signifi cantly higher in urban than in rural women (79.2 and 33.6%, respectively; p<0.05). Logistic regression analysis showed that the likelihood of belonging to the group defi ned as “very symptomatic” was greater for urban women [adjusted odds ratio (OR)=7.1; confi dence interval at 95% (95%CI)=3.69-13.66] who were literate (OR=2.19; 95%CI=1.16- 4.13). Individuals over the age of 60 years had less chance of having signifi cant symptoms (OR=0.38; 95%CI=0.17-0.87). CONCLUSIONS: the prevalence of signifi cant climacteric symptoms is less in women from a rural environment, showing that sociocultural and environmental factors are strongly related to the appearance of climacteric symptoms in our population

Syftet med detta examensarbete är att undersöka eventuella skillnader i likabehandlingsplaner i demografiskt olika kommuner samt hur diskrimineringsgrunderna används. Som metod har vi använt kvantitativ innehållsanalys och kvalitativ textanalys. Vi kunde se att det var skillnad på användningen av diskrimineringsgrunderna. Det var ingen tydlig skillnad beroende på demografin, men vi kunde se att förskolorna som kom från samma kommun var relativt lika. För att ta reda på mer om varför likabehandlingsplanerna såg ut på detta sätt undersökte vi de kommunala och statliga riktlinjerna för en likabehandlingsplan. Vi undersökte även likabehandlingsplanerna utifrån olika teman: Kontext, Utbytesord, Värdegrund, Ansvar och Delaktighet. Här kom vi fram till att fanns skillnader i hur likabehandlingsplanerna ser ut i förhållande till dessa. Slutsatsen av denna studie är att likabehandlingsplaner kan skilja sig åt på olika förskolor, men att det finns vissa riktlinjer som gör att innehållet ändå blir relativt likt. En annan slutsats är att forskningsområdet likabehandlingsplaner är eftersatt.
