Do therapist behaviors differ with Hispanic youth? A brief look at within-session therapist behaviors and youth treatment response.

Brief addiction treatments, including motivational interviewing (MI), have shown promise with youth. One underexamined factor in this equation is the role of therapist behaviors. We therefore sought to assess whether and how therapist behaviors differ for Hispanic versus non-Hispanic youth and how that may be related to treatment outcome. With 80 substance-using adolescents (M age = 16 years; 65% male; 59% Hispanic; 41% non-Hispanic), we examined the relationship between youth ethnicity and therapist behaviors across two brief treatments (MI and alcohol/marijuana education [AME]). We then explored relationships to youth 3-month treatment response across four target outcomes: binge drinking days, alcohol-related problems, marijuana use days, and marijuana-related problems. In this study, therapists showed significantly more MI skills within the MI condition and more didactic skills in the AME condition. With respect to youth ethnicity, across both conditions (MI and AME), therapists used less MI skills with Hispanic youth. Contrary to expectations, therapists' use of MI skills was not connected to poorer outcomes for Hispanic youth across the board (e.g., for binge drinking days, marijuana use days, or marijuana-related problems). Rather, for Hispanic youth, therapists' use of lower MI skills was related only to poorer treatment outcomes in the context of alcohol-related problems. The observed relationships highlight the importance of investigating salient treatment interactions between therapist factors and youth ethnicity to guide improvements in youth treatment response.

Relationship between obesity and the risk of clinically significant depression: Mendelian randomisation study.

BACKGROUND: Obesity has been shown to be associated with depression and it has been suggested that higher body mass index (BMI) increases the risk of depression and other common mental disorders. However, the causal relationship remains unclear and Mendelian randomisation, a form of instrumental variable analysis, has recently been employed to attempt to resolve this issue. AIMS: To investigate whether higher BMI increases the risk of major depression. METHOD: Two instrumental variable analyses were conducted to test the causal relationship between obesity and major depression in RADIANT, a large case-control study of major depression. We used a single nucleotide polymorphism (SNP) in FTO and a genetic risk score (GRS) based on 32 SNPs with well-established associations with BMI. RESULTS: Linear regression analysis, as expected, showed that individuals carrying more risk alleles of FTO or having higher score of GRS had a higher BMI. Probit regression suggested that higher BMI is associated with increased risk of major depression. However, our two instrumental variable analyses did not support a causal relationship between higher BMI and major depression (FTO genotype: coefficient -0.03, 95% CI -0.18 to 0.13, P = 0.73; GRS: coefficient -0.02, 95% CI -0.11 to 0.07, P = 0.62). CONCLUSIONS: Our instrumental variable analyses did not support a causal relationship between higher BMI and major depression. The positive associations of higher BMI with major depression in probit regression analyses might be explained by reverse causality and/or residual confounding.

Una aproximación a los entornos 1x1,«Un Ordenador Por Niño», desde las experiencias y las percepciones de los estudiantes de Educación Secundaria en el marco de la Sociedad Informacional

El presente trabajo emerge de la ejecución en Catalunya del proyecto"Las políticas de un «un laptop por niño» en España. Visiones y prácticas del profesorado en el Escuela 2.0 programa. Un análisis comparado entre comunidades autónomas, EDU2010-17037". Financiado en el marco del Plan Nacional I+D+i del Ministerio de Ciencia e Innovación. Se trata del primer estudio realizado en España que busca explorar los efectos e impactos que ha tenido la entrada masiva de las tecnologías en las aulas y escuelas del país, hecho impulsado en la actualidad por programa como el Escuela 2.0. Si bien la investigación se focaliza en la práctica y visión del profesorado, durante la ejecución del proyecto hemos podido conocer las vivencias y perspectivas de otros actores involucrados en la ejecución de este programa, entre ellos las del propio estudiantado. Con el fin de desarrollar esta dimensión, hemos centrado este artículo en desarrollar la siguiente pregunta. En el marco de los entornos 1x1, ¿Cual es la visión de los estudiantes de Educación Secundaria Obligatoria (ESO) ante la utilización de un ordenador en el aula, en el proceso de enseñanza /aprendizaje?

Elearning y la educación postmoderna: trayectorias y experiencias del estudiantado virtual

La emergencia y dinámica del Elearning, en los actuales escenarios de educación superior, evidencia una importante transformación acontecida en el marco de la sociedad de la información: la utilización de las TIC en los procesos de construcción del conocimiento. Este cambio ha ido de la mano, en primer lugar, de la mejora en la calidad y la oferta formativa existente, una oferta que ha buscado ser más inclusiva y representativa de las actuales demandas sociales. Y en segundo lugar, se trata de una modalidad que ha intentado adaptarse a las actuales características del estudiantado digital y del digitalizado (Prensky, 2006), cuyo rol en los proceso de enseñanza, tiende a ser más activo que en los modelos de formación tradicional. El presente artículo, se focaliza en esta segunda dimensión, analizando como el Elearning intenta ser un elemento de mediación entre las transformaciones actuales que se dan en la educación superior y la emergencia de un nuevo estudiantado virtual, cada vez más activo y autónomo.

Phenotypic Association Analyses With Copy Number Variation in Recurrent Depressive Disorder.

BACKGROUND: Defining the molecular genomic basis of the likelihood of developing depressive disorder is a considerable challenge. We previously associated rare, exonic deletion copy number variants (CNV) with recurrent depressive disorder (RDD). Sex chromosome abnormalities also have been observed to co-occur with RDD. METHODS: In this reanalysis of our RDD dataset (N = 3106 cases; 459 screened control samples and 2699 population control samples), we further investigated the role of larger CNVs and chromosomal abnormalities in RDD and performed association analyses with clinical data derived from this dataset. RESULTS: We found an enrichment of Turner's syndrome among cases of depression compared with the frequency observed in a large population sample (N = 34,910) of live-born infants collected in Denmark (two-sided p = .023, odds ratio = 7.76 [95% confidence interval = 1.79-33.6]), a case of diploid/triploid mosaicism, and several cases of uniparental isodisomy. In contrast to our previous analysis, large deletion CNVs were no more frequent in cases than control samples, although deletion CNVs in cases contained more genes than control samples (two-sided p = .0002). CONCLUSIONS: After statistical correction for multiple comparisons, our data do not support a substantial role for CNVs in RDD, although (as has been observed in similar samples) occasional cases may harbor large variants with etiological significance. Genetic pleiotropy and sample heterogeneity suggest that very large sample sizes are required to study conclusively the role of genetic variation in mood disorders.

Use of open educational resources at the UOC

The Open University of Catalonia (UOC: Universitat Oberta de Catalunya) is currently implementing its 2009-2014 Strategic Plan, which devotes an entire section to open educational resources. The working group on this topic is drafting a report that establishes the objectives to be met, analyses the current lay of the land and sets out the actions required to meet the objectives. This paper examines each of these three points.

MultiCampus Open Educational Resources : the case of OER-HE

In this paper we address the implementation strategies regarding Open Educational Resources within a multicampus setting. A comparison is made between 3 institutions that are taking a very different approach: K.U.Leuven, which is a traditional university, the Open Universiteit (Netherlands) which is in the process of starting up the Network Open Polytechnics, and the Universitat Oberta de Catalunya. We are looking deeper into the pedagogical and organizational issues involved in implementing an OER strategy and show how OER holds the promise of flexible solutions for reaching at first sight very divergent goals.

The situation of rural women in Spain: the case of small-scale artisan food producers

La discriminación de las mujeres rurales y la falta de una aplicación efectiva de la legislación sobre la igualdad de género es un fenómeno extendido alrededor del mundo. Las mujeres han sido tradicionalmente las responsables del cuidado y alimentación familiar, en consecuencia han desarrollado tareas productivas que facilitan la combinación de actividades productivas y reproductivas en la explotación agraria. La transformación alimentaria es una de esas actividades que permite a las mujeres tener un trabajo remunerado o complementar la renta agraria en un contexto dónde la mayoría de los trabajos agrícolas están vetados para ellas. Sin embargo, las mujeres suelen estar vinculadas a proyectos que priorizan la producción local y de calidad, y la expansión de la producción industrial de alimentos ha empeorado la situación de las mujeres artesanas alimentarias. En el presente estudio se pretende, mediante el uso de metodologías cualitativas, abordar un diagnóstico de la situación de las mujeres que llevan a cabo proyectos de transformación alimentaria a pequeña escala en España mostrando sus principales dificultades, necesidades y propuestas.

Adapting established instruments to build useful food sovereignty indicators

The recent context of global food emergency and ecological crisis has increased the relevance of people’s struggle for food sovereignty (FSv), which promotes the transformation of the dominant food system and claims ‘the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems’. Revisiting two Spanish and Catalan articles developing FSv indicators, this article aims at discussing the need and utility of developing FSv indicators at different territorial levels. Confronting these two territorial scales, the paper also identifies common steps that can facilitate other future processes of building FSv indicators. As a conclusion, the paper suggests that these processes of building indicators can contribute to providing political direction at different geographical scales for the implementation of the FSv proposal. At the same time, they favor the movement’s self-reflexivity in its practices while supporting the collective shaping of future actions

Dose calibrator linearity test: 99mTc versus 18F radioisotopes

Objective: The present study was aimed at evaluating the viability of replacing 18F with 99mTc in dose calibrator linearity testing. Materials and Methods: The test was performed with sources of 99mTc (62 GBq) and 18F (12 GBq) whose activities were measured up to values lower than 1 MBq. Ratios and deviations between experimental and theoretical 99mTc and 18F sources activities were calculated and subsequently compared. Results: Mean deviations between experimental and theoretical 99mTc and 18F sources activities were 0.56 (± 1.79)% and 0.92 (± 1.19)%, respectively. The mean ratio between activities indicated by the device for the 99mTc source as measured with the equipment pre-calibrated to measure 99mTc and 18F was 3.42 (± 0.06), and for the 18F source this ratio was 3.39 (± 0.05), values considered constant over the measurement time. Conclusion: The results of the linearity test using 99mTc were compatible with those obtained with the 18F source, indicating the viability of utilizing both radioisotopes in dose calibrator linearity testing. Such information in association with the high potential of radiation exposure and costs involved in 18F acquisition suggest 99mTc as the element of choice to perform dose calibrator linearity tests in centers that use 18F, without any detriment to the procedure as well as to the quality of the nuclear medicine service.

Worldwide trends in diabetes since 1980: a pooled analysis of 751 population-based studies with 4.4 million participants.

One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age-standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue. We used data from 751 studies including 4,372,000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4.3% (95% credible interval 2.4-7.0) in 1980 to 9.0% (7.2-11.1) in 2014 in men, and from 5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target. Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults affected, has increased faster in low-income and middle-income countries than in high-income countries. Wellcome Trust.

Entre la discapacitat i la diversitat funcional: El professional davant dels canvis de paradigmes i no només de paraules

En qualsevol disciplina els canvis en el vocabulari són importants pel fet que hi ha una evolució en la disciplina mateixa. Pel que fa a la discapacitat i la diversitat funcional no només hi ha un canvi de paraules sinó un canvi conceptual que genera substitucions de vocabulari però no com a sinònims. Els canvis de paradigma als quals fem referència en la darrera dècada comencen a prendre rellevància a molts nivells, com l’acadèmic, el social i el polític, com si fossin un engranatge en què, quan hi ha canvis en una peça, convé també plantejar-los en les altres. Des d’aquest punt de vista alteracions de la concepció de discapacitat i diversitat funcional generen canvis significatius en la manera de generar serveis si calgués. Però a més adquireixen molta importància les novetats a nivell actitudinal i de relació que estableixen els professionals de l’educació social o del treball social sobre les persones amb diversitat funcional.

Efecte del canvi climàtic sobre la ramaderia ecològica al Pirineu Occidental de Catalunya

Per tal d’arribar a la conclusió de si realment el Canvi climàtic és un factor limitant en el de venir de la Ramaderia ecològica al Pirineu Català, es proposen un seguit d’enquestes als afectats reals; els ramaders. La intenció és veure la percepció que se’n té i comparar-la amb la realitat de canvi climàtic, i més en zones d’alta muntanya: pujada de temperatures, disminució de la pluja i sequera, i desgel i tardança de les nevades. També el tema de l’erosió del sòl és de vital importància pel seu tractament. Cal desenvolupar una sèrie de millores per combatre els problemes de canvis climàtics, tot i que no són l’únic mal de cap del ramaders.
