Vulnerability to adverse consequences of drinking and problem drinker status as predicted by risky drinking behaviours, drug use, sex differences and affect : a test of multiple models /

Although alcohol problems and alcohol consumption are related, consumption does not fully account for differences in vulnerability to alcohol problems. Therefore, other factors should account for these differences. Based on previous research, it was hypothesized that risky drinking behaviours, illicit and prescription drug use, affect and sex differences would account for differences in vulnerability to alcohol problems while statistically controlling for overall alcohol consumption. Four models were developed that were intended to test the predictive ability of these factors, three of which tested the predictor sets separately and a fourth which tested them in a combined model. In addition, two distinct criterion variables were regressed on the predictors. One was a measure of the frequency that participants experienced negative consequences that they attributed to their drinking and the other was a measure of the extent to which participants perceived themselves to be problem drinkers. Each of the models was tested on four samples from different populations, including fIrst year university students, university students in their graduating year, a clinical sample of people in treatment for addiction, and a community sample of young adults randomly selected from the general population. Overall, support was found for each of the models and each of the predictors in accounting for differences in vulnerability to alcohol problems. In particular, the frequency with which people become intoxicated, frequency of illicit drug use and high levels of negative affect were strong and consistent predictors of vulnerability to alcohol problems across samples and criterion variables. With the exception of the clinical sample, the combined models predicted vulnerability to negative consequences better than vulnerability to problem drinker status. Among the clinical and community samples the combined model predicted problem drinker status better than in the student samples.

L’intimité chez les couples dont la femme présente une vulvodynie : étude des relations entre la réponse empathique, le dévoilement et le bien-être sexuel

L’étude de l’intimité a été négligée chez les couples dont la femme présente une vulvodynie, un problème de santé sexuelle qui affecte négativement les femmes et leurs partenaires. Or, l’intimité a été associée à des indicateurs d’adaptation psychologique et conjugale auprès d’autres populations cliniques. L’objectif de la thèse était d’examiner les liens entre l’intimité et le bien-être sexuel chez les femmes présentant de la vulvodynie et leurs partenaires. Le but du premier article était d’examiner l’intimité conjugale et l’intimité sexuelle en lien avec la satisfaction sexuelle, la fonction sexuelle, le sentiment d’auto-efficacité face à la douleur et l’intensité de la douleur vulvo-vaginale de la femme. Quatre-vingt-onze femmes présentant de la vulvodynie et leurs partenaires ont complété des mesures auto-rapportées. Chez les femmes, une plus grande intimité sexuelle a été associée à une satisfaction sexuelle et à un sentiment d’auto-efficacité plus élevés. Des degrés plus élevés d’intimité conjugale et sexuelle ont été associés à une fonction sexuelle plus élevée. L’intimité sexuelle et conjugale n’ont pas été associées à l’intensité de la douleur. Le deuxième article visait, par une méthodologie observationnelle et des mesures auto-rapportées, à examiner les associations entre deux composantes centrales de l’intimité – le dévoilement et la réponse empathique – et la satisfaction et la détresse sexuelle chez cinquante femmes et leurs partenaires. Le dévoilement et la réponse empathique ont été évalués selon la perspective d’une observatrice formée et auto-rapportés par les couples après une tâche de discussion. Les femmes et les partenaires ayant une plus grande réponse empathique rapportaient eux-mêmes une satisfaction sexuelle plus élevée. Pendant la discussion, une plus grande réponse empathique chez les femmes a été associée à une plus grande satisfaction sexuelle chez leurs partenaires. Un plus grand dévoilement chez le couple, tel que perçu par les femmes et leurs partenaires, a été associé à une plus grande satisfaction sexuelle chez les partenaires. Une plus grande réponse empathique chez les femmes a été associée à une plus faible détresse sexuelle chez les partenaires. Un plus grand dévoilement chez le couple, tel que perçu par les partenaires, a été associé à une plus faible détresse sexuelle chez ces derniers. Les implications cliniques, théoriques et méthodologiques de la thèse sont discutées.

Aplicación y desarrollo modelo de internacionalización : Jushi Design Limitada

El estudio de caso a desarrollar va a comprender la viabilidad de exportación de una empresa Colombiana llamada Jushi Design Limitada, la cual lleva 35 años en el mercado Colombiano con un gran reconocimiento en sus clientes y en el mercado mismo. Los casos de internacionalización de las empresa son hoy en día muy bien visto y de gran ejecución en las empresas colombianas debido al entorno en cual estamos viviendo, después de la apertura económica en el país las empresas se han puesto en la tarea de abrir sus mercados a otros países, como de igual manera importar productos de otros países, generando un comercio mucho más libre, sin fronteras u obstáculos. La globalización ha generado el intercambio de muchos productos ayudando al desarrollo de los países. Hoy en día el consumidor tiene la oportunidad de poder encontrar gran variedad de un solo producto en el mercado teniendo la posibilidad de elegir a sus necesidades la mejor opción. La ropa de moda femenina es un artículo en el cual las mujeres están muy al tanto de lo que sale y se comercializa sin olvidar las últimas tendencias y prendas que están a la moda. Es por esto que una empresa como Jushi Design Limitada con mucho tiempo en el mercado nacional está interesada en el desarrollo del plan exportador, así mismo el estar posesionado en las principales ciudades del país colombiano es de gran ayuda para el desarrollo de los objetivos planteados ya que se a preocupado por expandirse en el territorio nacional con sus prendas de últimas tendencias y gustos en las mujeres. No solo se realizara un estudio de viabilidad de exportación hacia la empresa Jushi Design Limitada si no también se buscara fortalezas y debilidades de la organización con el fin de poder contribuirle de alguna forma a la empresa sus problemas en los cuales frecuentan internamente y externamente. De esta forma entenderán cual es la salida a las diferentes debilidades que frecuentan dado el caso que las tengan. Es importante dar entender que por más que una empresa este en las mejores condiciones y posicionamiento en el mercado hay ciertas variables de las cuales toda empresa depende para el gran éxito y perdurabilidad en el tiempo, como lo son los aspectos políticos, sociales, económicos culturales entre otros. Todos estos son de gran fundamento para la consecución de los objetivos, buscar un país que cumpla con todas estas expectativas es muy importante para poder conseguir los objetivos planteados. Sin embargo nos basaremos en el aspecto comercial de Colombia frente al otro país ya que en este caso sería el primordial para encontrar el país indicado a realizar el estudio. Se realizara el diagnostico e investigación de mercados, con el fin de determinar tanto la situación de la empresa como la viabilidad en la que se encuentra, para la obtención del planteamiento del problema. Se buscara penetrar otros mercados con las diferentes colecciones que Jushi Design Limitada obtiene en el ano, de esta forma mostrara las últimas tendencias de la moda femeninas y sus diferentes y nuevos diseños en el mercado exterior. Las colecciones estarán fundamentas de acuerdo a la ocasión, clima y gusto de la persona, teniendo en cuenta aspectos como clima, moda, y ocasión en el cual este último está fundamentado mediante la época o momento en el cual está viviendo el cliente siendo en este caso la mujer.

De lo micro a lo macro prudencial: Un análisis de la supervisión bancaria desde la econometría espacial

La crisis que se desató en el mercado hipotecario en Estados Unidos en 2008 y que logró propagarse a lo largo de todo sistema financiero, dejó en evidencia el nivel de interconexión que actualmente existe entre las entidades del sector y sus relaciones con el sector productivo, dejando en evidencia la necesidad de identificar y caracterizar el riesgo sistémico inherente al sistema, para que de esta forma las entidades reguladoras busquen una estabilidad tanto individual, como del sistema en general. El presente documento muestra, a través de un modelo que combina el poder informativo de las redes y su adecuación a un modelo espacial auto regresivo (tipo panel), la importancia de incorporar al enfoque micro-prudencial (propuesto en Basilea II), una variable que capture el efecto de estar conectado con otras entidades, realizando así un análisis macro-prudencial (propuesto en Basilea III).

Influencia de la relación estratégica comunitaria y el marketing en la salud financiera de las organizaciones en mercados internacionales

La globalización de mercados ha generado una serie de cambios en la estructura del comercio internacional, como el surgimiento de áreas de libre comercio, que son el resultado de las integraciones económicas, las cuales han facilitado los flujos de capital, recursos y personas. La internacionalización no solamente se ha convertido en una estrategia para aprovechar las oportunidades que se dan en los mercados internacionales, sino también en un medio de diversificación del riesgo para reducir la dependencia del mercado doméstico. Sin embargo, para emprender un proceso de internacionalización, es necesario conocer muy bien el contexto dentro del cual se desarrollan los clientes, puesto que la falta de conocimiento del entorno puede perjudicar la salud financiera de la empresa. De ahí la importancia de utilizar una definición de comunidad y unas estrategias comunitarias con las cuales se identifiquen las necesidades, objetivos e intereses de la comunidad, para establecer un relación a largo plazo que procure el desarrollo de ambas partes. La relación estratégica comunitaria y el marketing impactan positivamente la salud financiera de la empresa, en la medida en que este desarrollo mutuo, tanto de la comunidad como de la empresa, no solamente incrementa el interés y el compromiso por seguir interactuando; también crea vínculos afectivos entre ambas partes, lo cual consolida aún más la perdurabilidad de la relación, logrando así una fidelización de los clientes y por ende aumentando la rentabilidad de la empresa.

Modeling the structure of amorphous MoS3: a neutron diffraction and reverse Monte Carlo study

A model for the structure of amorphous molybdenum trisulfide, a-MoS3, has been created using reverse Monte Carlo methods. This model, which consists of chains Of MoS6 units sharing three sulfurs with each of its two neighbors and forming alternate long, nonbonded, and short, bonded, Mo-Mo separations, is a good fit to the neutron diffraction data and is chemically and physically realistic. The paper identifies the limitations of previous models based on Mo-3 triangular clusters in accounting for the available experimental data.

Pricing and hedging short sterling options using artificial neural networks

This paper compares the performance of artificial neural networks (ANNs) with that of the modified Black model in both pricing and hedging Short Sterling options. Using high frequency data, standard and hybrid ANNs are trained to generate option prices. The hybrid ANN is significantly superior to both the modified Black model and the standard ANN in pricing call and put options. Hedge ratios for hedging Short Sterling options positions using Short Sterling futures are produced using the standard and hybrid ANN pricing models, the modified Black model, and also standard and hybrid ANNs trained directly on the hedge ratios. The performance of hedge ratios from ANNs directly trained on actual hedge ratios is significantly superior to those based on a pricing model, and to the modified Black model.

Climate models without pre-industrial volcanic forcing underestimate historical ocean thermal expansion

Episodic explosive volcanic eruptions are a natural part of the climate system but are often omitted from atmosphere-ocean general circulation model (AOGCM) preindustrial spin-up and control experiments. This omission imposes a negative bias on ocean heat uptake in simulations of the historical period. In models of a range of complexity, we find that global-mean sea level rise due to thermal expansion during the last ∼ 150 years is consequently underestimated by 5–30 mm, which is a substantial proportion of the model mean of 50 mm in Coupled Model Intercomparison Project Phase 3 AOGCMs with anthropogenic forcing only, and is therefore important in accounting for 20th century sea level rise. We test and recommend a procedure for removing the bias.

Accrual-based and real earnings management before and after IFRS adoption: the case of Greece

Purpose – The purpose of this study is to examine the use of accrual-based vs real earnings management (EM) by Greek firms, before and after the mandatory adoption of International Financial Reporting Standards (IFRS). The research is motivated by the fact that past studies have indicated the existence of significant levels of EM for Greece in particular before IFRS. Design/methodology/approach – Accrual-based earnings management (AEM) is examined by assessing performance-adjusted discretionary accruals, while real earnings management (REM) is defined in terms of abnormal levels of production costs, discretionary expenses, and cash flows from operations, for a three-year period before and after the adoption of IFRS in 2005. Findings – The authors find evidence on a statistically significant shift from AEM to REM after the adoption of IFRS, indicating the replacement of one form of EM with the other. Research limitations/implications – The validity of the results depends on the ability of the empirical models used to efficiently capture the existence of AEM and REM. Practical implications – IFRS adoption aims to improve accounting quality, especially in countries with high need for such an improvement; however, the tendency to substitute one form of EM with another highlights unintended consequences of IFRS adoption, which do not improve the informational content of financial statements if EM continues under different forms. Originality/value – Under the expectation that IFRS adoption should lead to improvements in accounting quality, this study examines whether IFRS actually led to a reduction of EM practices for a country with exceptionally high levels of EM before IFRS, by accounting for all possible forms of EM.

New use of global warming potentials to compare cumulative and short-lived climate pollutants

Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have requested guidance on common greenhouse gas metrics in accounting for Nationally determined contributions (NDCs) to emission reductions1. Metric choice can affect the relative emphasis placed on reductions of ‘cumulative climate pollutants’ such as carbon dioxide versus ‘short-lived climate pollutants’ (SLCPs), including methane and black carbon2, 3, 4, 5, 6. Here we show that the widely used 100-year global warming potential (GWP100) effectively measures the relative impact of both cumulative pollutants and SLCPs on realized warming 20–40 years after the time of emission. If the overall goal of climate policy is to limit peak warming, GWP100 therefore overstates the importance of current SLCP emissions unless stringent and immediate reductions of all climate pollutants result in temperatures nearing their peak soon after mid-century7, 8, 9, 10, which may be necessary to limit warming to “well below 2 °C” (ref. 1). The GWP100 can be used to approximately equate a one-off pulse emission of a cumulative pollutant and an indefinitely sustained change in the rate of emission of an SLCP11, 12, 13. The climate implications of traditional CO2-equivalent targets are ambiguous unless contributions from cumulative pollutants and SLCPs are specified separately.

"Dare to share!" : Bikt, moderskap och motstånd i Den stora mammabikten

”Dare to share!”: Confession, motherhood and resistance in The great mother confession This article explore the meaning of confession in a commercial, secular event – The great mother confession (TGM). The event is understood as imbedded in a therapeutic culture where emotional disclosure, in the form of confessions, is a highly valued practice. In a web-based confession-blog that constitutes part of the TGM-concept, confessions serve to free mothers from supressing norms. The blog becomes an arena for a volatile community where burdening and ”forbidden” thoughts and emotions becomes generalised and disarmed, releasing mothers from guilt. When this function of the blog is questioned from a competing sub-discourse of the therapeutic, emphasising the disclosure of happiness, a struggle emerges over the authority to define the meanings of confession. TGM can be understood as having potential for serving as an arena for challenging norms, but even as norms are implicitly addressed the practice makes a halt at that point. Norms that are seemingly dissolved in responses to confessions are not questioned, only recognised, normalised and de-politicised.

Therapeutic Discourse and the American Public Philosophy: On American Liberalism's Troubled Relationship with Psychology

I explore the main currents of postwar American liberalism. One, sociological, emerged in response to the danger of mass movements. Articulated primarily by political sociologists and psychologists and ascendant from the mid-fifties till the mid-seventies, it heralded the "end of ideology." It emphasized stability, elitism, positive science and pluralism; it recast normatively sound politics as logrolling and hard bargaining. I argue that these normative features, attractive when considered in isolation, taken together led to a vicious ad hominem style in accounting for views outside the postwar consensus. It used pseudo-scientific literature in labeling populists, Progressives, Taft conservatives, Goldwaterites, the New Left and others "pathological," viz. mentally ill. Hence, "therapeutic discourse." I argue that philosophical liberalism, which reasserts the role of political theory in working out norms and adjudicating disagreement, is a more profitable way of thinking about and defending from critics liberalism. I take the philosopher John Rawls as the tradition's modern representative. This inquiry is important because the themes of sociological liberalism are making a comeback in American public discourse, and with them perhaps the baggage of therapeutic discourse. I present a cautionary tale.

Da memória dos trabalhadores à memória da Petrobras: a história de um projeto

Como reflexo de um movimento mundial onde a memória se tornou um valor nas sociedades contemporâneas, também as empresas estão investindo na organização e preservação de suas memórias e um sem número de iniciativas materializou-se na publicação de livros, exposições, criação de “museus virtuais” e fundação de Centros de Documentação ou de Memória. Neste trabalho analisamos como a história das empresas vem sendo organizada com base na experiência do programa Memória Petrobras. Ao longo de 6 anos a estatal implementou um amplo conjunto de iniciativas voltadas para a recuperação dos marcos históricos da empresa, ordenação de dados, coleta de depoimentos e preparação de um suporte de pesquisa e divulgação materializado em um museu virtual. Discutimos a relevância desta proposta no conjunto de outras iniciativas semelhantes no âmbito da história das empresas.

Transformação estrutural na América Latina

I investigate the role of sectoral di¤erences in labor productivity and the process of structural transformation (reallocation of labor across sectors) in accounting for the time path of aggregate productivity across six Latin American countries (Brazil, Chile, Argentina, Colombia, Mexico and Venezuela) during the period from 1950 to 2003. Although they have started the process of structural transformation in di¤erent times, all of them went through a common process. I consider a simple three-sector-model of structural transformation and calibrate it to the experience of the six latin american economies. I use the model to measure sectoral labor productivity di¤erences between these countries and the United States. I have found that the services sector can explain the recent decrease of labor productivity in Brazil, Argentina and Mexico, after these countries had gone through a catch up in relative productivity (considering the United States as a benchmark) during the period from 1950 to 1980. Among Latin American economies, only the Chilean one has been catching up in relative productivity from 1980 to the present. There are some cases like Colombia, Mexico and Venezuela that the ine¢ ciency of all sectors was responsible for the failure in reducing the gap of productivity in relation to the United States during the last years of the sample.
