Psychosocial measures reported by parents in studies of skin cancer prevention

Background. Because it is important to minimize children's sun exposure to reduce skin cancer risk, much of the extensive skin cancer prevention literature consists of studies of children's sun protection, sun avoidance and ultraviolet radiation (UVR) exposure. Little attention has been focused on the measurement of psychosocial constructs in these studies. Identification of the psychosocial correlates or determinants of children's skin cancer risk or risk-reduction behavior is critical to more fully understand and predict behavior. Furthermore, psychosocial variables may be influenced by interventions to reduce risk. Thus, it is important to examine the psychosocial measures used in studies of children's skin cancer prevention. Information on the validity and reliability of psychosocial measures may increase confidence in study findings based on these measures. In particular, self-efficacy and barriers are key constructs in several major theoretical frameworks and parental measures have been associated with children's sun protection. However, there is conceptual overlap of self-efficacy and barriers measures and little is known about the psychometric properties of these measures.^ Study Aims and Methods. The overall goal of this dissertation was to examine the measurement of psychosocial constructs relevant to children's skin cancer prevention. Because children depend primarily on their parents for skin cancer prevention, measures of parents' psychosocial constructs are the focus. Study 1 was a systematic review of parental psychosocial measures used in studies of children's sun protection, sun avoidance and UVR exposure. The specific aims of Study 1 were to (1) describe psychosocial measures reported by parents, including available information on the psychometric properties of these measures and their use in analyses and (2) provide recommendations for the development, refinement and standardized reporting of measures. ^ Study 2 examined the psychometric properties of measures of parental self-efficacy and barriers regarding children's sun protection. Melanoma patients (N=205) who were parents of children ≤ 12 years of age completed a telephone interview that included self-efficacy and barriers measures specific to sunscreen, clothing, shade and limiting time outdoors. The specific aims of Study 2 were to (1) use a confirmatory factor analytic approach to examine the factorial validity of parental self-efficacy and barriers measures, (2) examine the convergent and discriminant validity of behavior-specific measures of self-efficacy and barriers and (3) assess the reliability of item and scale measures.^ Results. In Study 1, a search of standard databases yielded 48 eligible studies. Most studies assessed only one or two psychosocial constructs. Knowledge was measured most frequently. There was little discussion of measure source, development, theoretical background or psychometric properties, besides internal consistency reliability. There was conceptual overlap of some measures. In Study 2, confirmatory factor analytic findings supported the factorial validity of the self-efficacy and barriers measures. When all eight self-efficacy and barriers measures were included in the same model, a modified eight-factor model adequately fit the data, providing preliminary evidence that the measures are distinct. Measure associations supported the convergent validity of all measures and the discriminant validity of most measures. The self-efficacy and barriers measures were reliable.^ Conclusions. Recommendations based on the literature review include developing and refining psychosocial measures based on theory. Describing a measure's theoretical basis and psychometric properties would facilitate critical evaluation. Standardized reporting of source, development, theory, construct, items and analytic role would facilitate comparison of findings, continual refinement and future applications of measures. In the validation study, self-efficacy and barriers measures were examined in a sample of parents with a personal history of melanoma. Findings suggested that these measures are valid and reliable for use in studies of children's sun protection. There was preliminary evidence that these measures are distinct but additional study is needed. ^

Factors associated with needle sharing among Black male injection drug users in Harris County, Texas

Background. Injection drug users (IDUs) are at increased risk for HIV transmission due to unique risk behaviors, such as sharing needles. In Houston, IDUs account for 18% of all HIV/AIDS cases among Black males. ^ Objectives. This analysis compared demographic, behavioral, and psychosocial characteristics of needle sharing and non-sharing IDUs in a population of Black males in Harris County, Texas. ^ Methods. Data used for this analysis were from the second IDU cycle of the National HIV Behavioral Surveillance System. This dataset included a sample of 288 Black male IDUs. Univariate and multivariate statistical analysis were performed to determine statistically significant associations of needle sharing in this population and to create a functional model to inform local HIV prevention programs. ^ Results. Half of the participants in this analysis shared needles in the past 12 months. Compared to non-sharers, sharers were more likely to be homeless (OR=3.70, p<0.01) or arrested in the past year (OR=2.31, p<0.01), inject cocaine (OR=2.07, p<0.01), report male-to-male sex in the past year (OR=6.97, p<0.01), and to exchange sex for money or drugs. Sharers were less likely than non-sharers to graduate high school (OR=0.36, p<0.01), earn $5,000 or more a year (OR=1.15, p=0.05), get needles from a medical source (OR=0.59, p=0.03), and ever test for HIV (OR=0.17, p<0.01). Sharers were more likely to report depressive symptoms (OR=3.49, p<0.01), lower scores on the family support scale (mean difference 0.41, p=0.01) and decision-making confidence scale (mean difference 0.38, p<0.01), and greater risk-taking (mean difference -0.49, p<0.01) than non-sharers. In a multivariable logistic regression, sharers were less likely to have graduated high school (OR=0.33, p<0.01) and have been tested for HIV (OR=0.12, p<0.01) and were more likely to have been arrested in the past year (OR=2.3, p<0.01), get needles from a street source (OR=3.87, p<0.01), report male-to-male sex (OR=7.01, p<0.01), and have depressive symptoms (OR=2.36, p=0.02) and increased risk-taking (OR=1.78, p=0.01). ^ Conclusions. IDUs that shared needles are different from those that did not, reporting lower socioeconomic status, increased sexual and risk behaviors, increased depressive symptoms and increased risk-taking. These findings suggest that intervention programs that also address these demographic, behavioral, and psychosocial factors may be more successful in decreasing needle sharing among this population.^

A descriptive and exploratory analysis of occupational injuries at a chemical manufacturing facility

A retrospective study of 1353 occupational injuries occurring at a chemical manufacturing facility in Houston, Texas from January, 1982 through May, 1988 was performed to investigate the etiology of the occupational injury process. Injury incidence rates were calculated for various sub-populations of workers to determine differences in the risk of injury for various groups. Linear modeling techniques were used to determine the association between certain collected independent variables and severity of an injury event. Finally, two sub-groups of the worker population, shiftworkers and injury recidivists, were examined. An injury recidivist as defined is any worker experiencing one or more injury per year. Overall, female shiftworkers evidenced the highest average injury incidence rate compared to all other worker groups analyzed. Although the female shiftworkers were younger and less experienced, the etiology of their increased risk of injury remains unclear, although the rigors of performing shiftwork itself or ergonomic factors are suspect. In general, females were injured more frequently than males, but they did not incur more severe injuries. For all workers, many injuries were caused by erroneous or foregone training, and risk taking behaviors. Injuries of these types are avoidable. The distribution of injuries by severity level was bimodal; either injuries were of minor or major severity with only a small number of cases falling in between. Of the variables collected, only the type of injury incurred and the worker's titlecode were statistically significantly associated with injury severity. Shiftworkers did not sustain more severe injuries than other worker groups. Injury to shiftworkers varied as a 24-hour pattern; the greatest number occurred between 1200-1230 hours, (p = 0.002) by Cosinor analysis. Recidivists made up 3.3% of the population (23 males and 10 females), yet suffered 17.8% of the injuries. Although past research suggests that injury recidivism is a random statistical event, analysis of the data by logistic regression implicates gender, area worked, age and job titlecode as being statistically significantly related to injury recidivism at this facility. ^

THE DEVELOPMENT OF COMMUNITY COMPETENCE THROUGH A NEIGHBORHOOD ORGANIZATION (LOS ANGELES, MEXICAN-AMERICAN)

This investigation focused on how people cope with the demands of their environment in a competent manner. It sought to assess the effects of learning competent coping behaviors on self-reported well-being. The study chose a community-evolved, organized effort on the part of a group of neighborhoods to build competence in the Mexican-American community of East Los Angeles. This network was a citizen-action organization called the United Neighborhoods Organization. UNO was selected because it concentrated on developing community leaders by using spiritual beliefs and family values as shared community resources. Neighborhood leaders were encouraged to engage in risk-taking and confrontation maneuvers. They were also taught problem-solving skills and provided with social support.^ A survey instrument was developed to assess sociodemographic characteristics, acculturation history and status, willingness to engage in risk-taking and confrontation and self-perceived general well-being. The study relied on eight months of daily participant-observation of the organization, the East Los Angeles environment and the interaction between the two. At the end of the observation period, a sample of 150 UNO participants were given the survey questionnaire as was a matched group of 150 non-UNO participants who were ELA residents.^ The study sample was mostly women, in their middle age years who had lived in the area from 5 to more than 30 years. Significantly more single persons were found in the UNO group. The sample was almost equally divided into English and Spanish speaking respondents. Acculturatively almost all the sample fell in the Very Mexican and Mostly Mexican types. The survey found a trend of association between participating in UNO and reporting feeling well. A statistically significant association was found among UNO participants between taking risks and reporting feeling well, regardless of a tendency for all the sample to minimize risk. A trend was seen for married UNO participants to report feeling well. Slightly more UNO participants were willing to engage in confrontation and a substantial proportion of the participants who were confronters reported feeling well in comparison to their counterparts. Ethnic pride was positively associated with participation in UNO and showed a trend in the expected direction with reported self-perceived well-being. ^

Comparing Campus Discipline Rates: A Multivariate Approach for Identifying Schools with Significantly Different than Expected Exclusionary Discipline Rates

Campus behavior management is important for ensuring classroom order and promoting positive academic outcomes. Previous studies have shown the importance of individual student and campus personnel characteristics and campus context for explaining campus discipline rates (e.g., rates of suspension and expulsion). Assessing campus discipline rates, while controlling for these individual and campus characteristics, is important for the monitoring, evaluation, and intervention role of policymakers as well as state and federal level education agencies. Systems or metrics exist that measure other student outcomes (i.e., academic performance) with controls for individual and campus characteristics, but none exist that monitor these differences for discipline rates across campuses. In this paper, we use a multivariate model to analyze a longitudinal, statewide dataset for all secondary students in Texas from 2000 to 2008 in order to examine how campus discipline rates differ across schools with statistically similar students, teachers, and campus characteristics. The findings are important for understanding that some schools with similar characteristics have significantly different exclusionary discipline rates, and they are important for informing policy and agency level decision-making. The methodology described can easily be used by monitoring agencies as well as local school districts.

Tecnología e incertidumbre en la práctica del riego en la provincia de Córdoba

En el presente trabajo se busca caracterizar a los regantes de Río Segundo, Córdoba, en términos comparativos y en vinculación con la tecnología. Se trata de pequeños y medianos productores localizados en el Espinal cordobés, límite de la región pampeana argentina, que se dedican a la agricultura extensiva de cereales y oleaginosas utilizando riego suplementario con agua subterránea. El objeto de estudio se aborda considerando que las lógicas de conocimiento atraviesan la producción y que el crecimiento de la incertidumbre es impulsado por la práctica de la innovación y la búsqueda de eficiencia. La gestión profesionalizada de la producción que lleva a la planificación de las actividades productivas en base a la reflexión permanente, revela la necesidad de conocer aquello que aún no se conoce, lo cual está en relación directa con la incertidumbre y con una mayor toma conciencia de los riesgos, tanto climáticos como económicos que se vinculan con la producción. Para alcanzar los objetivos propuestos se utilizó una metodología cualitativa basada en el trabajo de campo, la realización de entrevistas en profundidad y un marco interpretativo crítico complementado con elementos de la teoría social del riesgo.

Pasiones del riesgo y contacto con la naturaleza

Muchos deportistas aficionados en occidente, están emprendiendo hoy en día, largas e intensas ordalías donde la capacidad personal de resistir al sufrimiento en aumento constituye el objetivo principal. La carrera, el footing, el triatlón, el trekking, etc., son tipos de ordalías en las que la gente, sin apoyarse en una habilidad específica, no compite contra otros, sino que somete a prueba su propia capacidad para soportar el dolor creciente. El individuo se evalúa constantemente a sí mismo en una sociedad donde los puntos de referencia son incontables y contradictorios, donde los valores están en crisis, y busca entonces una relación cercana con significados profundos, probando su fuerza de carácter, su coraje y sus recursos personales. Seguir adelante hasta final de las ordalías autoimpuestas da una legitimidad a la vida y provee un umbral simbólico en el cual apoyarse. El funcionamiento en sí mismo tiene una importancia secundaria; sólo cuenta para el individuo. No se trata de luchar contra un tercero, es sólo un método para reforzar la voluntad personal y vencer el sufrimiento, justo al límite de una demanda personalmente impuesta. El límite físico ha venido a sustituir el límite moral que la sociedad actual no logra proporcionar. Sobreponiéndose al sufrimiento se templa el carácter del individuo, proporcionando así una importancia renovada y valiosa a su vida

Time to Set Banking Regulation Right. CEPS Paperbacks. March 2012

Excessive leverage and risk-taking by large international banks were the main causes of the 2008-09 financial crisis and the ensuing sharp drop in economic activity and employment. World leaders and central bankers promised that it would not happen again and, to this end, undertook to overhaul banking regulation, first and foremost by rectifying Basel prudential rules. This study argues that the new Basel III Accord and the ensuing EU Capital Requirements Directive IV fail to correct the two main shortcomings of international prudential rules: 1) reliance on banks’ risk management models for the calculation of capital requirements and 2) the lack of accountability by supervisors. Accordingly, the authors propose the calculation of capital requirements without risk adjustment and creation of a system of mandated action by supervisors modelled on the US framework of Prompt Corrective Action (PCA). They also recommend that banks should be required to issue large amounts of debentures that are convertible into equity in order to strengthen market discipline on management and shareholders.

Discussions in Europe on Variable Compensation in the Financial Sector. EU Centre Singapore Working Paper no. 20, February 2014

Bonuses – which are often used to mitigate principal-agent problems and to encourage employees to work harder – have increased tremendously in the financial sector during the last decade, and have often been seen as a contributing factor to the financial crisis of 2008. The recent European Union (EU) action to adopt a policy that restricts bonuses paid to bankers may seem promising at first, but this does not address the real issues behind variable rewards. Compensation policies should be changed to encourage responsible risk-taking and decision-making through the implementation of broader performance metrics, forfeitable holdbacks and hybrid bonds. Furthermore, a change in organisational culture is needed to improve ethical behaviour leading to a re-balancing of stakeholders’ interests in the financial sector.

Fine-tuning the use of bail-in to promote a stronger EU financial system. CEPS Special Report No. 136/April 2016

This paper discusses the application of the new European rules for burden-sharing and bail-in in the banking sector, in view of their ability to accommodate broader policy goals of aggregate financial stability. It finds that the Treaty principles and the new discipline of state aid and the restructuring of banks provide a solid framework for combating moral hazard and removing incentives that encourage excessive risk-taking by bankers. However, the application of the new rules may have become excessively attentive to the case-by-case evaluation of individual institutions, while perhaps losing sight of the aggregate policy needs of the banking system. Indeed, in this first phase of the banking union, while large segments of the EU banking sector still require a substantial restructuring and recapitalisation, the market may not be able to provide all the needed resources in the current environment of depressed profitability and low growth. Thus, a systemic market failure may be making the problem impossible to fix without resorting to temporary public support. But the risk of large write-offs of capital instruments due to burden-sharing and bail-in may represent an insurmountable obstacle to such public support as it may set in motion an investors’ flight. The paper concludes by showing that existing rules do contain the flexibility required to accommodate aggregate policy requirements in the general interest, and outlines a public support scheme for the precautionary recapitalisation of solvent banks that would be compliant with EU law.

Políticas de salvamento e risco bancário em período de crise

Esta tese analisa, entre 2005 e 2013, o impacto das políticas governamentais de resgate sobre o risco do setor bancário nos países da OCDE. Primeiro, em linha com a hipótese de moral hazard, verifica-se que instituições financeiras com expectativa elevada de bailout, assumem riscos mais elevados do que as demais. Segundo, constata-se que, em períodos normais, garantias de socorro às grandes instituições distorcem a competição no setor e incrementa o risco das demais. Durante a crise, entretanto, mostra-se que elevações na expectativa de resgate dos concorrentes de uma instituição, à medida que representa uma redução em sua chance de eventual socorro governamental, diminuem sua tomada de riscos. Adicionalmente, em período de crise também é evidenciado que: reduções na capacidade financeira dos países estão associadas a menor assunção de riscos; em média, o aumento na tomada de riscos é maior nos países com menor spread de Credit Default Swap.
