This is the second edition of the compendium. Since the first edition a number of important initiatives have been launched in the shape of large projects targeting integration of research infrastructure and new technology for toxicity studies and exposure monitoring.The demand for research in the area of human health and environmental safety management of nanotechnologies is present since a decade and identified by several landmark reports and studies. Several guidance documents have been published. It is not the intention of this compendium to report on these as they are widely available.It is also not the intention to publish scientific papers and research results as this task is covered by scientific conferences and the peer reviewed press.The intention of the compendium is to bring together researchers, create synergy in their work, and establish links and communication between them mainly during the actual research phase before publication of results. Towards this purpose we find useful to give emphasis to communication of projects strategic aims, extensive coverage of specific work objectives and of methods used in research, strengthening human capacities and laboratories infrastructure, supporting collaboration for common goals and joint elaboration of future plans, without compromising scientific publication potential or IP Rights.These targets are far from being achieved with the publication in its present shape. We shall continue working, though, and hope with the assistance of the research community to make significant progress. The publication will take the shape of a dynamic, frequently updated, web-based document available free of charge to all interested parties. Researchers in this domain are invited to join the effort, communicating the work being done. [Auteurs]

Mismatch negativity (MMN) overlaps with other auditory event-related potential (ERP) components. We examined the ERPs of 50 9- to 11-year-old children for vowels /i/, /y/ and equivalent complex tones. The goal was to separate MMN from obligatory ERP components using principal component analysis and equal probability control condition. In addition to the contrast of the deviant minus standard response, we employed the contrast of the deviant minus control response, to see whether the obligatory processing contributes to MMN in children. When looking for differences in speech deviant minus standard contrast, MMN starts around 112 ms. However, when both contrasts are examined, MMN emerges for speech at 160 ms whereas for nonspeech MMN is observed at 112 ms regardless of contrast. We argue that this discriminative response to speech stimuli at 112 ms is obligatory in nature rather than reflecting change detection processing.

[cat] Una qüestió clau sobre la producció de salut relativament poc explorada es refereix a la influència dels factors socioeconòmics i mediambientals sobre el pes i l’obesitat. Aquesta problemàtica adquireix particular rellevància quan es comparen dos països Mediterranis com Itàlia i Espanya. És interessant adonar-se que l’obesitat a Espanya és 5 punts percentual més elevada al 2003 mentre que a l’any 1990 era aproximadament la mateixa en ambdós països. Aquesta article presenta una descomposició no lineal dels gaps o diferencials en taxes de sobrepès (índex de massa corporal – IMC- entre 25 i 29.9 9 kg/m2), obesitat classe 1 (IMC≥30 kg/m2) i classe 2 (IMC≥35 kg/m2) entre Espanya i Itàlia per gènere i grups d’edat. En explicar aquests gaps entre països aïllem les influències dels estils de vida, els efectes socioeconòmics i els mediambientals. Els nostres resultats indiquen que quan no es controla pels efectes mediambientals (efectes de grup o ‘peer effects’) els hàbits alimentaris i el nivell educatiu són els principals predictors del gaps totals entre països (36-52%), si bé aquests dos factors exerceixen un impacte diferenciat segons gènere i edat. Un tant paradoxalment, quan controlem pels efectes de grup aquests predictors perden la seva capacitat explicativa i els efectes de grup passen a explicar entre el 46-76% dels gaps en sobrepès i obesitat i mostren un patró creixent amb l’edat.

Perceiving injustice is a key antecedent of a large range of undesirable employee attitudes and behaviors at work. For example, research has shown that employees who perceive their workplace as unfair are less satisfied, less committed and engage in more counterproductive behaviors. In this study, we suggest that justice motives like the belief in a just world (BJW) contribute to explaining relations between justice perceptions and undesirable behaviors. Specifically, we propose that individual differences in BJW (i.e, the belief that the world is just, where everyone is rewarded for his or her behavior) are related to work-related behaviors and attitudes by coloring perceptions of workplace fairness. We investigated our hypotheses in a survey study with 176 employees of various organizations (36% women; mean tenure 12.3 yeares). Results showed that after controlling for other influencing factors (e.g., neuroticism) BJW was negatively related to self-reported work deviant behaviors and to cynical, disillusioned attitudes toward the current job. Moreover, BJW was positively related to overall job satisfaction. Consistent with our expectations, relations of BJW with deviant behaviors and with attitudes were mediated by perceptions of interactional and procedural justice. These results suggest extending models of justice and deviance by including motives such as BJW.

PURPOSE: To determine the characteristics specific to boys with disordered eating behaviors (DEB) and the general context in which these DEB occur. METHOD: Data were drawn from the SMASH02 database, a survey carried out among post-mandatory school students in Switzerland aged 16-20 years in 2002. Only males (N=3890) were included, and were classified into into one of four groups based on their level of concern about weight/food and on their eating behaviors, as follows: group 1: one concern without behavior (N=862); group 2: more than one concern without behavior (N=361); group 3: at least one behavior (N=798); and a control group (N=1869), according to previously validated items. Groups were compared for personal, family, school, experience of violence, and health-compromising behaviors variables on the bivariate level. All significant variables were included in a multinomial logistic regression using Stata 9 software. RESULTS: About one-half of the boys reported either a concern or unhealthy eating behavior. Compared with the control group, boys from the three groups were more likely to be students and to report a history of sexual abuse, delinquency, depression, and feeling fat. In addition, boys from group 3 were more likely to report a history of dieting, early puberty, peer teasing, having experienced violence, frequent inebriation, and being overweight. CONCLUSION: DEB concern adolescent males more frequently than thought and seem to be integrated in a general dysfunctional context, in which violence is predominant. Adolescent males also need to be screened for DEB. Moreover, prevention programs should target the increasing social and media pressure regarding boys ideal body shape and raise public consciousness about this phenomenon.

BACKGROUND: Many clinical studies are ultimately not fully published in peer-reviewed journals. Underreporting of clinical research is wasteful and can result in biased estimates of treatment effect or harm, leading to recommendations that are inappropriate or even dangerous. METHODS: We assembled a cohort of clinical studies approved 2000-2002 by the Research Ethics Committee of the University of Freiburg, Germany. Published full articles were searched in electronic databases and investigators contacted. Data on study characteristics were extracted from protocols and corresponding publications. We characterized the cohort, quantified its publication outcome and compared protocols and publications for selected aspects. RESULTS: Of 917 approved studies, 807 were started and 110 were not, either locally or as a whole. Of the started studies, 576 (71%) were completed according to protocol, 128 (16%) discontinued and 42 (5%) are still ongoing; for 61 (8%) there was no information about their course. We identified 782 full publications corresponding to 419 of the 807 initiated studies; the publication proportion was 52% (95% CI: 0.48-0.55). Study design was not significantly associated with subsequent publication. Multicentre status, international collaboration, large sample size and commercial or non-commercial funding were positively associated with subsequent publication. Commercial funding was mentioned in 203 (48%) protocols and in 205 (49%) of the publications. In most published studies (339; 81%) this information corresponded between protocol and publication. Most studies were published in English (367; 88%); some in German (25; 6%) or both languages (27; 6%). The local investigators were listed as (co-)authors in the publications corresponding to 259 (62%) studies. CONCLUSION: Half of the clinical research conducted at a large German university medical centre remains unpublished; future research is built on an incomplete database. Research resources are likely wasted as neither health care professionals nor patients nor policy makers can use the results when making decisions.

The objective of this research was to determine whether the level of parental monitoring is associated with substance use among adolescents in Switzerland, and to assess whether this effect remains when these adolescents have consuming peers. For this purpose, we used a nationally representative sample from the Swiss participation in the 2007 European School Project on Alcohol and Other Drugs survey, which included 7,611 adolescents in public schools (8th-10th grades). Four levels of parental control were created and four substances (tobacco, alcohol, cannabis, and ecstasy) were analyzed. All significant variables at the bivariate level were included in the multivariate analysis. Most adolescents had a high level of parental monitoring and that was associated with younger age, females, high socioeconomic status, intact family structure, and satisfactory relationships with mother, father, and peers. Overall, substance use decreased as parental monitoring increased and high parental monitoring decreased as having consuming peers increased. Results remained essentially the same when the variable "having consuming peers" was added to the analysis. Conclusion: parental monitoring is associated to positive effects on adolescent substance use with a reduction of consumption and a lower probability of having consuming peers, which seems to protect adolescents against potentially negative peer influence. Encouraging parents to monitor their adolescents' activities and friendships by establishing rules about what is allowed or not is a way to limit the negative influence of consuming peers on adolescent substance use.

El fenómeno y/o la cuestión del conflicto en el escenario educativo es un temacomplejo pero a la vez muy relevante, para las diferentes problemáticas sociales,que afectan a los sistemas educativos actualmente. Este puede ser abordado desdediversas perspectivas y se le añade la dificultad para su identificación, análisis yvaloración para su adecuada resolución y/o gestión a través de las buenas praxis, yasea a través de la mediación o de otras intervenciones de naturaleza similar. Elconflicto en la Institución Educativa (IE) es inherente a las relaciones sociales,mantiene una estrecha relación con la convivencia entre todos los agentes socialesde la comunidad educativa (docentes, alumnos, familias, etc.). Y, en función de lagestión del conflicto, se podrán observar consecuencias en la salud, concretamenteen el bienestar o malestar de los implicados. Galtung (2003), entre otros autores,apuesta por una perspectiva positiva del conflicto, donde éste se convierte en lafuerza y el motivo por el cambio personal y social. Lederach (2000) asume que elconflicto supone una interacción entre dos adversarios que compiten por susintereses pero que necesitan de la cooperación para alcanzar acuerdos, y sirve parael crecimiento personal. Vinyamata (2005) nos dice que el conflicto es el motor y laexpresión de las relaciones humanas. Por tanto, podemos decir que se trata de una"vivencia subjetiva o una experiencia de los implicados en las relaciones humanasen un entorno determinado". Desde una perspectiva positiva el conflicto, puedeconvertirse en un motivo o un estímulo para el bienestar y la promoción de la salud,generando cambios sociales y personales que se correspondan con las aspiracioneslegítimas, pero también puede ser una fuente de malestar y de obstáculos para eldesarrollo de la labor educadora y de las relaciones humanas y profesionalessaludables...

This handbook describes the peer review methodology that was applied at the GODIAC project fi eld studies1. The peer review evaluation method as initiated by Otto Adang in the Netherlands and further developed in a European football context (Adang & Brown, 2008) involves experienced police offi cers cooperating with researchers to perform observational fi eld studies to identify good practices and learning points for public order management. The handbook builds on the GODIAC seminars and workshops, for the fi eld study members, which took place in September 2010, January 2012 and January 2013. The handbook has been discussed in the project group and in the steering committee. It is primarily written for the GODIAC fi eld study members as background material for understanding the fi eld study process and for clarifying the different responsibilities that enable active participation in the fi eld study. The handbook has been developed during the project period and incorporates learning points and developments of the peer review method. The handbook aims at promoting the use of fi eld studies for evaluation of policing major events.

L'objectif principal de cette thèse est d'exposer les résultats des premières évaluations psychopathologiques menées, dans le cadre d'une étude familiale, sur une cohorte d'enfants de patients souffrant de troubles liés à des substances ou de troubles de l'humeur. Plus précisément, nous avons examiné des enfants de patients souffrant de dépendance à l'alcool et à l'héroïne, de troubles bipolaires et unipolaires, ainsi qu'un groupe d'enfants témoins, dont les parents étaient des patients contrôles recrutés dans des départements d'orthopédie. Nous nous sommes ainsi proposé d'étudier de façon précise le risque de psychopathologie chez des enfants de parents malades en menant une étude longitudinale prospective au moyen d'évaluations standardisées. Ces enfants ainsi que leurs parents-patients (probands) sont actuellement évalués chaque trois ans. Nous avons aussi effectué une évaluation des co-parents biologiques de ces enfants afin de tenir compte également de l'impact de leurs éventuels troubles psychiatriques sur les manifestations psychopathologiques de leurs enfants. Le volet longitudinal-prospectif de ces familles est actuellement en cours, et les deux articles contenus dans cette thèse, publiés dans des revues à politique éditoriale, exposent les résultats obtenus lors de l'évaluation initiale de ces enfants et de leurs deux parents. Nous résultats montrent que les enfants de patients, pourtant encore très jeunes (moyenne d'âge d'environ 11 ans), présentent déjà de plus hauts taux de manifestations psychopathologiques que les enfants de parents contrôles. Nous avons également pu démontrer le rôle joué par le co-parent, en plus de celui du parent-patient, dans le développement de psychopathologie chez ces enfants. Ces résultats soulignent la nécessité d'une identification et d'une prise en charge très précoce de ces enfants, et indiquent également l'importance de porter un intérêt clinique non seulement au parent-patient, mais également au co-parent de ces enfants. - This thesis presents the baseline results of psychopathological assessments conducted in a prospective longitudinal cohort study of children whose parents have substance use disorders or mood disorders. More specifically, we examined children of alcohol- and heroin- dependent patients, children of patients with bipolar or unipolar disorders, and, as a control group, children whose parents were recruited in orthopedics departments. Using standardized assessments, we conducted this study to accurately assess the risk of psychopathology in children of parents with these substance use or mood disorders. The prospective longitudinal study of these families is currently ongoing, with the children and their parent-patients (probands) being followed up every three years. We also assessed the biological co-parent in order to determine the impact of their possible psychiatric disorders on the risk of mental disorders in offspring. The two articles of this thesis, which have been published in peer-reviewed journals, present the results of baseline assessments of the children and their two parents. Our results show that the children of patients who are still very young at baseline assessment (mean age about 11 years) already have higher rates of psychopathological manifestations compared with children of control parents. We also demonstrate the effect of the co-parents, in addition to that of the parent-patients, on the development of early psychiatric manifestations in these children. These results emphasize the importance of prompt identification and treatment of these children and highlight the need for clinical care not only of the patient, but also of the co- parent, in order to optimize the prevention of mental disorders in their offspring.

A network of 25 sonic stage sensors were deployed in the Squaw Creek basin upstream from Ames Iowa to determine if the state-of-the-art distributed hydrological model CUENCAS can produce reliable information for all road crossings including those that cross small creeks draining basins as small as 1 sq. mile. A hydraulic model was implemented for the major tributaries of the Squaw Creek where IFC sonic instruments were deployed and it was coupled to CUENCAS to validate the predictions made at small tributaries in the basin. This study demonstrates that the predictions made by the hydrological model at internal locations in the basins are as accurate as the predictions made at the outlet of the basin. Final rating curves based on surveyed cross sections were developed for the 22 IFC-bridge sites that are currently operating, and routine forecast is provided at those locations (see IFIS). Rating curves were developed for 60 additional bridge locations in the basin, however, we do not use those rating curves for routine forecast because the lack of accuracy of LiDAR derived cross sections is not optimal. The results of our work form the basis for two papers that have been submitted for publication to the Journal of Hydrological Engineering. Peer review of our work will gives a strong footing to our ability to expand our results from the pilot Squaw Creek basin to all basins in Iowa.
