Symptom Check-List-90-R: fiabilidad, datos normativos y estructura factorial en estudiantes universitarios

El Symptom Checklist-90-R (SCL-90-R) es uno de los instrumentos más ampliamente utilizados en la medición de la sintomatología psicopatológica en población clínica y en población general. Ya que gran parte de la investigación en psicopatología se realiza con estudiantes universitarios, este estudio instrumental pretende proporcionar datos de referencia para esta población. Analizamos las propiedades psicométricas de esta escala en una muestra representativa de 1.277 estudiantes de la Universidad de Girona. Las dimensiones con puntuaciones más elevadas para el total de la muestra son Obsesividad-compulsividad, Depresión y Sensibilidad interpersonal. Los resultados muestran diferencias significativas entre hombres y mujeres. La fiabilidad de la escala resulta muy aceptable, con unos coeficientes de consistencia interna de las nueve dimensiones primarias y del GSI, que oscilan entre 0,69 y 0,97. El análisis de la estructura factorial y la fuerte interdependencia entre las escalas primarias cuestionan la multidimensionalidad del SCL-90-R y refuerzan la idea de que el instrumento proporciona una medida de distrés general, es decir, es un indicador unidimensional de malestar psicológico más que una medida de dimensiones psicopatológicas diferenciadas

Basic life support teaching in the second year predraduate medical curriculum: quality of acquisition after 6 months

Purpose of the study: Basic life support (BLS) and automated externaldefibrillation (AED) represent important skills to be acquired duringpregraduate medical training. Since 3 years, our medical school hasintroduced a BLS-AED course (with certification) for all second yearmedical students. Few reports about quality and persistence over timeof BLS-AED learning are available to date in the medical literature.Comprehensive evaluation of students' acquired skills was performedat the end of the 2008 academic year, 6 month after certification.Materials and methods: The students (N = 142) were evaluated duringa 9 minutes «objective structured clinical examination» (OSCE) station.Out of a standardized scenario, they had to recognize a cardiac arrestsituation and start a resuscitation process. Their performance wererecorded on a PC using an Ambuman(TM) mannequin and the AmbuCPR software kit(TM) during a minimum of 8 cycles (30 compressions:2 ventilations each). BLS parameters were systematically checked. Nostudent-rater interactions were allowed during the whole evaluation.Results: Response of the victim was checked by 99% of the students(N = 140), 96% (N = 136) called for an ambulance and/or an AED. Openthe airway and check breathing were done by 96% (N = 137), 92% (N =132) gave 2 rescue breaths. Pulse was checked by 95% (N=135), 100%(N = 142) begun chest compression, 96% (N = 136) within 1 minute.Chest compression rate was 101 ± 18 per minute (mean ± SD), depthcompression 43 ± 8 mm, 97% (N = 138) respected a compressionventilationratio of 30:2.Conclusions: Quality of BLS skills acquisition is maintained during a6-month period after a BLS-AED certification. Main targets of 2005 AHAguidelines were well respected. This analysis represents one of thelargest evaluations of specific BLS teaching efficiency reported. Furtherfollow-up is needed to control the persistence of these skills during alonger time period and noteworthy at the end of the pregraduatemedical curriculum.

Spatial statistical analysis and selection of genotypes in plant breeding

The objective of this study was to evaluate the efficiency of spatial statistical analysis in the selection of genotypes in a plant breeding program and, particularly, to demonstrate the benefits of the approach when experimental observations are not spatially independent. The basic material of this study was a yield trial of soybean lines, with five check varieties (of fixed effect) and 110 test lines (of random effects), in an augmented block design. The spatial analysis used a random field linear model (RFML), with a covariance function estimated from the residuals of the analysis considering independent errors. Results showed a residual autocorrelation of significant magnitude and extension (range), which allowed a better discrimination among genotypes (increase of the power of statistical tests, reduction in the standard errors of estimates and predictors, and a greater amplitude of predictor values) when the spatial analysis was applied. Furthermore, the spatial analysis led to a different ranking of the genetic materials, in comparison with the non-spatial analysis, and a selection less influenced by local variation effects was obtained.

Digital forensic osteology--possibilities in cooperation with the Virtopsy project.

The present study was carried out to check whether classic osteometric parameters can be determined from the 3D reconstructions of MSCT (multislice computed tomography) scans acquired in the context of the Virtopsy project. To this end, four isolated and macerated skulls were examined by six examiners. First the skulls were conventionally (manually) measured using 32 internationally accepted linear measurements. Then the skulls were scanned by the use of MSCT with slice thicknesses of 1.25 mm and 0.63 mm, and the 33 measurements were virtually determined on the digital 3D reconstructions of the skulls. The results of the traditional and the digital measurements were compared for each examiner to figure out variations. Furthermore, several parameters were measured on the cranium and postcranium during an autopsy and compared to the values that had been measured on a 3D reconstruction from a previously acquired postmortem MSCT scan. The results indicate that equivalent osteometric values can be obtained from digital 3D reconstructions from MSCT scans using a slice thickness of 1.25 mm, and from conventional manual examinations. The measurements taken from a corpse during an autopsy could also be validated with the methods used for the digital 3D reconstructions in the context of the Virtopsy project. Future aims are the assessment and biostatistical evaluation in respect to sex, age and stature of all data sets stored in the Virtopsy project so far, as well as of future data sets. Furthermore, a definition of new parameters, only measurable with the aid of MSCT data would be conceivable.

Speaking in the CLIL classroom: to what extent do teachers and students use english in the classroom?

L'objectiu principal d'aquesta investigació va ser determinar els efectes del CLIL en els professors i estudiants en les seves produccions orals. El punt de partida de la meva investigació era de la teoria de Dalton-Puffer (2007), que estableix que la funció de parlar en les classes CLIL és mínima, la meva recerca s'ha basat en la recopilació recollir informació des de diferents fonts, amb la finalitat de veure si aquest fet també passa a les nostres escoles. Eventualment, he planejat algunes estratègies i activitats per incrementar la quantitat d’oportunitats per parlar en llengua anglesa els alumnes.

A protocol for a systematic review on the impact of unpublished studies and studies published in the gray literature in meta-analyses.

BACKGROUND: Meta-analyses are particularly vulnerable to the effects of publication bias. Despite methodologists' best efforts to locate all evidence for a given topic the most comprehensive searches are likely to miss unpublished studies and studies that are published in the gray literature only. If the results of the missing studies differ systematically from the published ones, a meta-analysis will be biased with an inaccurate assessment of the intervention's effects.As part of the OPEN project (http://www.open-project.eu) we will conduct a systematic review with the following objectives:â-ª To assess the impact of studies that are not published or published in the gray literature on pooled effect estimates in meta-analyses (quantitative measure).â-ª To assess whether the inclusion of unpublished studies or studies published in the gray literature leads to different conclusions in meta-analyses (qualitative measure). METHODS/DESIGN: Inclusion criteria: Methodological research projects of a cohort of meta-analyses which compare the effect of the inclusion or exclusion of unpublished studies or studies published in the gray literature.Literature search: To identify relevant research projects we will conduct electronic searches in Medline, Embase and The Cochrane Library; check reference lists; and contact experts.Outcomes: 1) The extent to which the effect estimate in a meta-analyses changes with the inclusion or exclusion of studies that were not published or published in the gray literature; and 2) the extent to which the inclusion of unpublished studies impacts the meta-analyses' conclusions.Data collection: Information will be collected on the area of health care; the number of meta-analyses included in the methodological research project; the number of studies included in the meta-analyses; the number of study participants; the number and type of unpublished studies; studies published in the gray literature and published studies; the sources used to retrieve studies that are unpublished, published in the gray literature, or commercially published; and the validity of the methodological research project.Data synthesis: Data synthesis will involve descriptive and statistical summaries of the findings of the included methodological research projects. DISCUSSION: Results are expected to be publicly available in the middle of 2013.

Latex production with depolymerizing compounds of actin cytoskeleton in rubber trees

The objective of this work was to assess stimulated latex flow from rubber trees (Hevea brasiliensis) with saturated macrolide (latrunculin A), 1, 5, and 10% potassium iodide in 2% methylcellulose compared with 0.3% ethylene in 2% methylcellulose (check) and 2% methylcellulose (blank). Latex output and contents of pure rubber, total solid, sucrose, inorganic phosphorus, thiol, and Mg2+ were measured. The treatments containing 1% KI or saturated macrolide increased latex yields compared to the blank with 2% methylcellulose alone. The 1% KI or saturated macrolide treatments were equal to that of 0.3% ethylene check treatment. However, 5 and 10% KI were harmful to bark of rubber trees, even caused prolonged tapping panel dryness.

Antiretroviral adherence program in HIV patients: a feasibility study in the Swiss HIV Cohort Study.

Objective To evaluate the feasibility of a comprehensive, interdisciplinary adherence program aimed at HIV patients. Setting Two centers of the Swiss HIV Cohort Study: Lausanne and Basel. Method 6-month, pilot, quasi-experimental, 2-arm design (control and intervention). Patients starting a first or second combined antiretroviral therapy line were invited to participate in the study. Patients entering the intervention arm were proposed a multifactorial intervention along with an electronic drug monitor. It consisted of a maximum of six 30-min sessions with the interventionist coinciding with routine HIV check-up. The sessions relied on individualized semi-structured motivational interviews. Patients in the control arm used directly blinded EDM and did not participate in motivational interviews. Main outcome measures Rate of patients' acceptance to take part in the HIV-adherence program and rate of patients' retention in this program assessed in both intervention and control groups. Persistence, execution and adherence. Results The study was feasible in one center but not in the other one. Hence, the control group previously planned in Basel was recruited in Lausanne. Inclusion rate was 84% (n = 21) in the intervention versus 52% (n = 11) in the control group (P = 0.027). Retention rate was 91% in the intervention versus 82% in the control group (P = ns). Regarding adherence, execution was high in both groups (97 vs. 95%). Interestingly, the statistical model showed that adherence decreased more quickly in the control versus the intervention group (interaction group × time P < 0.0001). Conclusion The encountered difficulties rely on the implementation, i.e., on the program and the health care system levels rather than on the patient level. Implementation needs to be evaluated further; to be feasible a new adherence program needs to fit into the daily routine of the centre and has to be supported by all trained healthcare providers. However, this study shows that patients' adherence behavior evolved differently in both groups; it decreased more quickly over time in the control than in the intervention group. RCTs are eventually needed to assess the clinical impact of such an adherence program and to verify whether skilled pharmacists can ensure continuity of care for HIV outpatients.

QTLs for resistance to soybean cyst nematode, races 3, 9, and 14 in cultivar Hartwig

The objective of this work was to identify major and minor-effect quantitative trait loci (QTL) for resistance to races 3, 9, and 14 of soybean cyst nematode (SCN) in Hartwig cultivar; to map new resistance QTLs for these races; and to check for the existence of epistatic interactions between QTLs. Cultivar Hartwig is an important resistance source to SCN. Recombinant inbred lines (RIL) obtained from a cross between 'Hartwig' (resistant) and Y23 (susceptible) were evaluated regarding resistance to the three races. New genomic regions for resistance to SCN were identified by microsatellites. Four QTLs, which explained between 12 and 34% of phenotypic variance, were detected for resistance to race 3 in linkage groups (LG) A2, G, J, and M. The QTL in LG G is also important for resistance to race 9. Epistatic interactions were detected between loci, which indicate resistance to races 9 and 14. There are high and low-effect resistance QTLs to SCN.

Women in leadership: Three essays

GENDER EMPOWERMENT: EFFECTS OF GODS, GEOGRAPHY, AND GDP¦Fenley, M., & Antonakis, J.¦ABSTRACT¦We examined the determinants of women's empowerment in the economy and political leadership in 178 countries. Given the androcentric nature of most religions, we hypothesized that high degrees of country-level theistic belief create social conditions that impede the progression of women to power. The dependent variable was the Gender Empowerment index of the United Nations Development Program, which captures the participation of women in political leadership, management, and their share of national income. Controlling for GDP per capita as well as the fixed-effects of the dominant type of religion and legal origin and instrumenting all endogenous variables with geographic or historical variables, our results show that atheism has a significant positive effect on gender empowerment. These results are driven by the rule of law, which in addition to being a catalyst for economic development, appears to crowd-out the informal regulation of behavior due to religious norms.¦DEVELOPING WOMEN LEADERS: COMPARING A TRANSFORMATIONAL AND A CHARISMATIC LEADERSHIP INTERVENTION¦Fenley, M., Jacquart, P., & Antonakis, J.¦ABSTRACT¦Along with a gender imbalance in leadership role occupancy, most leadership interventions have been conducted with samples of men. We conducted an experiment wherein we assigned female participants (n = 38, mean age = 35 years) to one of two conditions: Transformational (i.e., "standard") leadership training or charismatic leadership training. The two interventions were essentially equivalent, except that we also focused on developing the "charismatic leadership tactics" (e.g., rhetorical skills) of participants in the charismatic condition. After the interventions, we randomly assigned participants into problem-solving teams that required extensive interaction. Each team had an equal number of participants having received transformational training or charismatic training. At the end of the team exercises, participants rated each of their team members on a leadership prototypicality measure. Results indicated that those who received charismatic training scored higher (a) on prototypicality (standardized  = .42) and (b) on a test of declarative knowledge of charismatic rhetorical strategies (i.e., a manipulation check, standardized  = .76). Furthermore, the score on the test fully mediated the effect of the treatment on prototypicality (standardized indirect  = .32). We discuss the importance and practical implications of these results.¦CHANGING ATTITUDES TOWARDS WOMEN IN A MALE SEX-TYPE WORK ENVIRONMENT: EVIDENCE FROM A FIELD EXPERIMENT IN EUROPEAN ATHLETICS¦Fenley, M.¦ABSTRACT¦Most sports organizations have a similar gender gap in leadership as do the majority of non-sport organizations. Women's careers sputter somewhere at coaching level positions and few women obtain top leadership positions. Greater awareness of gender inequalities in general, and in leadership in particular, could decrease gender discrimination and increase women's presence at upper levels. The goal of this study was to evaluate the impact of an intervention using an online gender awareness exercise. Participants (n = 1,001 participants, n = 32 countries) were randomly assigned to one of eight conditions in a 2 (a discriminating perspective-taking story or a non-discriminating perspective-taking story) by 2 (gender quiz or no gender quiz) by 2 (diversity quiz or no diversity quiz) factorial design. The results show that the online perspective taking exercise changed initial sexist attitudes. Participants having taken a diversity quiz had less sexist attitudes (as measured by the Modern- and Old-fashioned sexism scale) than did participants who did not take the diversity quiz (irrespective of perspective-taking story). The combination of having taken a diversity quiz with a gender quiz had the biggest impact on attitudes for the non-discriminating story.

Seroepidemiology of herpes simplex virus type 1 and 2 in pregnant women in Switzerland: an obstetric clinic based study.

OBJECTIVE: To assess the seroprevalence of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) IgG antibodies and the seroincidence of HSV-1 and HSV-2 infections in pregnant women attending the maternity clinic of the University Hospital Lausanne. STUDY DESIGN: Blood samples from 1030 women were taken at the usual pregnancy visit in the first trimester to assess the prevalence rate of IgG antibodies against HSV-1 and HSV-2 using a type-specific assay. A second blood sample was taken 6-8 weeks postpartum from returning women who were seronegative for HSV-2 or HSV-1 to assess the incidence of seroconversion (primary infection). RESULTS: The seroprevalence rates were 79.4% (95% CI: 76.9-81.9) for HSV-1 and 21.2% (18.7-23.7) for HSV-2 in women 14-46 years old. Type-specific serostatus patterns were as follows: 17.3% HSV-1/-2: +/+, 62.1% HSV-1/-2: +/-, 3.9% HSV-1/-2: -/+, 16.7% HSV-1/-2: -/-. Two hundred and sixty five women (59 of the 212 seronegative for HSV-1 (27.8%) and 265 of the 812 seronegative for HSV-2 (32.6%)) returned to the outpatient clinic for the post-delivery check and a second blood sample was obtained. One HSV-1 seroconversion was detected (HSV-1 seroconversion rate 2.4%/100 patient×year (95% CI: 0.06-13.4)) in a patient who had symptoms compatible with primary genital herpes. No HSV-2 seroconversion was detected (HSV-2 seroconversion rate: 0/100 patient×year (97.5% one-sided CI: 0-2)). CONCLUSION: Compared to a previous population-based study, our study results suggest a rise in the prevalence of HSV-2 among pregnant women in Switzerland. The low incidence of seroconversion detected during pregnancy is consistent with the very low reported incidence of neonatal herpes in Switzerland. CONDENSATION: This study in a public hospital in Western Switzerland suggests an increasing prevalence of HSV-2, but a low incidence of primary infections in women of childbearing age.

Residues of carbosulfan and its carbofuran metabolites and 3-hydroxy-carbofuran in oranges

The objectives of this study were to evaluate the residues of the insecticide carbosulfan and its carbofuran metabolites and 3-hydroxy-carbofuran in orange compartments (whole fruit, bagasse and juice) and comparison between the residual levels found in fruits with the maximum residue level and the safety interval established by the Brazilian legislation. Two field experiments were carried out, both with the following treatments: a-check; b-one application of 10 g of carbosulfan . 100 L-1 of water; c-one application with twice the rate applied in treatment b; d-four applications with the same rate applied in treatment b. Samples were taken at (-1), zero, 1, 3, 7, 14, 21 and 28 days after the last or unique application. The quantitative determinations were done by gas chromatography technique, using a nitrogen-phosphorus detector. The carbosulfan metabolism to its carbofuran metabolite was rapid (3 days), being both analytes concentrated in the bagasse (peel + flavedo + albedo). However, the metabolism of carbofuran to 3-hydroxy-carbofuran was of low intensity or this metabolite was quickly dissipated. Carbosulfan residues and its metabolites did not penetrate into the fruit, thus not contaminating the juice. The use of the pesticide was adequate, with respect to fruit consumption, in relation to the Brazilian legislation.

Effects of crop and weed densities on the interactions between barley and Lolium rigidum in several Mediterranean locations

The effects of both barley and Lolium rigidum densities on weed growth and spike production and on crop yield were examined in five field experiments carried out in the Mediterranean drylands of Spain and Western Australia. The aim was to check the consistency of the competitiveness of the crop in different environmental and management conditions. L. rigidum reduced barley yields in most of the experiments (between 0 and 85%), the number of ears per m2 being the most affected. It was found that increasing the barley seeding rate did not reduce the crop losses but did limit weed biomass (between 5 and 61%) and spike production (between 24 and 85%). The variability observed in crop yield losses between sites and seasons was related to rainfall at the beginning of the season. The most sensitive component of yield to weed competition was the number of ears per plant.
