The European School Survey Project on Alcohol and Drugs : Swiss Findings

L'enquête 'European School Survey Project on Alcohol and other Drugs' (ESPAD) est menée tous les quatre ans dans de nombreux pays européens auprès d'écolières et d'écoliers âgés de 15 ans, un âge important en matière de prévention. La dernière vague de l'enquête a été réalisée en 2003; il s'agissait de la première participation de la Suisse à l'enquête. Un peu moins de 7000 élèves des 8e, 9e et 10e années scolaires ont participé au volet suisse de l'enquête. Les résultats montrent notamment que 21.1% des adolescente- s de 15 ans fument quotidiennement, la part des fumeurs quotidiens passant de 8.5% chez les 13 ans à 23.2% chez les 16 ans. Plus de 50% des adolescent-e-s de 13 ans ont consommé de l'alcool durant les 30 jours précédant l'enquête. Chez les 15 ans, pour lesquels l'achat d'alcool est d'ailleurs aussi interdit par la loi, cette proportion passe à 75%. L'enquête 2003 montre en outre qu'environ 20% des adolescent-e-s de 13 ans ont consommé au moins une fois du cannabis dans leur vie et que près de la moitié des 16 ans sont dans le même cas. La prévalence au cours des 12 derniers mois est à peine inférieure. En matière de prévention de la consommation de substances psychotropes chez les jeunes, les mesures structurelles devraient être renforcées, tout comme la limitation de l'accessibilité des produits, en contrôlant par exemple la vente d'alcool aux plus jeunes. Des programmes éducatifs et des campagnes médiatiques peuvent également exercer une certaine influence, pour autant qu'ils s'intègrent à une politique cohérente en matière de drogues.

Regulation of the vascular gap junctions in a mouse model of intimal hyperplasia

Objective: Intimal hyperplasia (IH) is one of the leading causes of failure¦after vascular interventions. It involves the proliferation of smooth muscle¦cells (SMCs) and the production of extracellular fibrous matrix. Gap junctional¦communication, mediated by membrane connexins (Cx), participates to the¦control of proliferation and migration. In human and mice vessels, endothelial¦cells (ECs) express Cx37, Cx40 and Cx43, whereas SMCs are coupled by Cx43.¦We previously reported that Cx43 was increased in the SMCs of a human vein¦during the development of IH.¦In our experimental model of mice carotid artery ligation (CAL), luminal¦narrowing occurred by SMCs-rich neointima after 2-4 weeks of ligation.¦This experimental model of mice allows us to decipher the regulation of the¦cardiovascular connexins in the mouse.¦Methods: C57BL/6 mice were anesthetized and the left common carotid artery¦was dissected through a neck incision and ligated near the carotid bifurcation.¦The mice were then euthanized at 7, 14 and 28 days. Morphometric analyses¦were then performed with measurements of total area, lumen and intimal area¦and media thickness. Western blots, immunocytochemistry and quantitative¦RT-PCR were performed for Cx43, Cx40 and Cx37.¦Results: All animals recovered with no symptom of stroke. Morphometric¦analysis demonstrated that carotid ligation resulted in an initial increase (after¦7 days) of the total vessel area followed by its reduction (after 28 days). This¦phenomena was associated with a progressive increase in the intimal area and a¦consecutive decrease of the lumen. The media thickness was also increased after¦14 and 28 days. This neointima formation was associated to a marked increase¦in the expression of Cx43 at both protein and RNA levels. Concomitantly,¦Cx40 and Cx37 protein expression were reduced in the endothelium. This was¦confirmed by en face analyses showing reduced Cx37 and Cx40 levels in the¦endothelial cells covering the lesion.¦Conclusion: This study assessed the regulation of the cardiovascular connexins¦in the development of IH. This model will allow us to characterize the¦involvement of gap junctions in the IH. In turn, this understanding is¦instrumental for the development of new therapeutical tools, as well as for¦the evaluation of the effects of drugs and gene therapies of this disease for which¦there is no efficient therapy available.

Validation of a modified fluorimetric assay for the screening of trichomonacidal drugs

A fluorimetric microassay that uses a redox dye to determine the viability of the flagellate Trichomonas vaginalis has been optimised to provide a more sensitive method to evaluate potential trichomonacidal compounds. Resazurin has been used in recent years to test drugs against different parasites, including trichomonadid protozoa; however, the reproducibility of these resazurin-based methods in our laboratory has been limited because the flagellate culture medium spontaneously reduces the resazurin. The objective of this work was to refine the fluorimetric microassay method previously developed by other research groups to reduce the fluorescence background generated by the media and increase the sensitivity of the screening assay. The experimental conditions, time of incubation, resazurin concentration and media used in the microtitre plates were adjusted. Different drug sensitivity studies against T. vaginalis were developed using the 5-nitroimidazole reference drugs, new 5-nitroindazolinones and 5-nitroindazole synthetic derivatives. Haemocytometer count results were compared with the resazurin assay using a 10% solution of 3 mM resazurin dissolved in phosphate buffered saline with glucose (1 mg/mL). The fluorimetric assay and the haemocytometer counts resulted in similar percentages of trichomonacidal activity in all the experiments, demonstrating that the fluorimetric microtitre assay has the necessary accuracy for high-throughput screening of new drugs against T. vaginalis.

Spatio-temporal micromeasurements of the oxygen uptake in the developing chick embryo.

A method has been developed for the determination of the oxygen uptake of small areas (0.01 mm2) in an entire chick embryo cultured in vitro under defined metabolic conditions. It is based on the recordings of the spectral changes of the hemoglobin used as oxygen source for the respiring tissue (Barzu and Borza, 1967). Rapid scanning of the hemoglobin absorbance over the preparation allows a comparison of the O2 uptake of various regions. Values of the order of 10(-2) 1 O2 . min-2 are measured in less than 10 sec with a spatial resolution of 100 micron. The differentiation of embryonic tissue is not disturbed by the measurements. The O2 diffusion in the media and in the tissue has been analyzed by digital simulation. The O2 uptake of the Hensen's node was measured from embryos starting at the stage of definitive primitive streak (stage 4) up to the stage of 10 somites. It increases from 0.6 to 1.1 nl . h-1 with a marked acceleration between stages 4 and 5. The values corrected for the protein content of the Hensen's node at stage 4, 5, 6 and 8 are 32, 30 and 28 microliter . mg-1 . h-1 respectively. The first scanning results show different patterns of the O2 utake at the level of the Hensen's node and of the neural plate. At stage 6-7, the corrected O2 uptake is 30 microliter . mg-1 . h-1 for . the former and 43 microliter . mg-1 . h-1 for the latter.

NEWSPAPERS FOLHA DE SÃO PAULO E CORREIO BRAZILIENSE: WHAT THEY SAY ABOUT THE PROGRAM MORE DOCTORS?

Analyzes publications related More Medical Program from July to September of 2013 and its impact on Correio Braziliense and Folha de São Paulo. This is a descriptive study using a qualitative-quantitative methodology. The analyzed and related data represent what the program takes in print. 363 publications were found, 262 in Folha de São Paulo and 101 in Correio. The word "Doctor" appeared in more titles, and Folha de São Paulo were 110 negative titles; to Correio neutral character was in 50 publications. In the character of news, 178 of these are pessimistic. The "neutral" and 101 representing "optimistic" 83. Was found that the media is critical to the impact of the program, but the truth is not apparent, but the opinion of journalists who wrote the stories related to the theme.

Cross-cultural adaptation of the Caregiver Reaction Assessment for use in Brazil with informal caregivers of the elderly

This study aimed to carry out the cross-cultural adaptation of the Caregiver Reaction Assessment CRA for use in Brazil with informal caregivers of dependent elderly METHOD A methodological study, of five steps: initial translation, synthesis of translations, retro-translation, evaluation by a judge committee and a pre-test, with 30 informal caregivers of older persons in Fortaleza, Brazil. Content validity was assessed by five experts in gerontology and geriatrics. The cross-cultural adaptation was rigorously conducted, allowing for inferring credibility. RESULTS The Brazilian version of the CRA had a simple and fast application (ten minutes), easily understood by the target audience. It is semantically, idiomatically, experimentally and conceptually equivalent to the original version, with valid content to assess the burden of informal caregivers for the elderly (Content Validity Index = 0.883). CONCLUSION It is necessary that other psychometric properties of validity and reliability are tested before using in care practice and research.

The housing boom and forest fires

This paper provides evidence that the combination of land-use restrictions and anincreasing demand for housing can create incentives to induce forest fires as a means tocircumvent regulation and increase the supply of land available for residential construction.I estimate the effect of the price of housing on the incidence of forest fires using Spanishdata by region for 1991-2005. The results suggest that higher house prices led to asignificant increase in the incidence of forest fires in a region. I also find that the increasedincidence of forest fires led to a subsequent reduction in forest area and an increase in urbanland area. This evidence supports the claims often found in the media that propertyspeculators trying to build in forest land may be behind the recent increases in the incidenceof forest fires in Mediterranean countries.

Sports and journalism ethics: the coverage of 2012 London Olympics in the British, North-American and Spanish press

Sports and journalism ethics: the coverage of 2012 London Olympics in the British, North-American and Spanish press is a research focused on analysing the treatment that the quality press of three countries (United Kingdom, United States of America and Spain) will carry out in the London Olympic Games. Through a solid methodological approach based on the combination of the qualitative content analysis and qualitative indepth interviews, the investigation will study if the media provide a quality coverage,that is, if they adequate their pieces to the fundamental principles of journalistic deontology (truth, justice, freedom and social responsibility). Furthermore, the research will assess if the selected media comply with the prescriptions established in the ethical codes, stylebooks, newsroom statutes and national and international recommendations about journalism ethics, ranging from each media’s guidelines to key transnational codes established by the UNESCO, the International Federation of Journalists (IFJ) orthe Council of Europe.

Public perceptions of collectives at the outbreak of the H1N1 epidemic: Heroes, villains and victims

Lay perceptions of collectives (e.g., groups, organizations, countries) implicated in the 2009 H1N1 outbreak were studied. Collectives serve symbolic functions to help laypersons make sense of the uncertainty involved in a disease outbreak. We argue that lay representations are dramatized, featuring characters like heroes, villains and victims. In interviews conducted soon after the outbreak, 47 Swiss respondents discussed the risk posed by H1N1, its origins and effects, and protective measures. Countries were the most frequent collectives mentioned. Poor, underdeveloped countries were depicted as victims, albeit ambivalently, as they were viewed as partly responsible for their own plight. Experts (physicians, researchers) and political and health authorities were depicted as heroes. Two villains emerged: the media (viewed as fear mongering or as a puppet serving powerful interests) and private corporations (e.g., the pharmaceutical industry). Laypersons' framing of disease threat diverges substantially from official perspectives.

Homicide-suicide cases in Switzerland and their impact on the Swiss Weapon Law.

Homicide followed by the suicide of the offender is a well-known phenomenon. In most cases, it takes place in the context of the so-called "family tragedies." A recent series of such family tragedies in Switzerland prompted an intensive debate in the media and the Swiss government concerning the Swiss Weapon Law, in particular the requirement to keep personal army weapons at home. The present study of Homicide-Suicide cases in Switzerland, thus focuses on the role played by guns, especially military weapons, in such crimes. We investigated retrospectively 75 cases of Homicide-Suicide, comprising 172 individuals and spanning a period of 23 years in western and central Switzerland. Our results show that if guns were used in 76% of the cases, army weapons were the cause of death in 25% of the total. In 28% of the deaths caused by a gunshot, the exact type of the gun and its origin could not be determined. Thus, the majority of Homicide-Suicide cases in Switzerland involve the use of guns. The exact percentage of cases were military weapons were involved could not be defined. In our opinion, a stricter weapons law, restricting access to firearms, would be a factor of prevention of Homicide- Suicide cases in Switzerland.

Media, investors and bubbles

We analysed the specific case of how information in the financial press influences economic bubbles. We found considerable flaws in the information market due to several factors: demand, the predominance of what are termed “irrational investors” (herding), and supply, which has the problem that the sources of information are biasedand feeds. A financial bubble is a deviation between real value of a financial asset and its persistent market price in time, which also has a speculative origin fed back by the illusion of the owners of these financial values, who will take benefits because of the future prices, which must be higher than the previous ones. The economical information in the media is submitting three problems. First of all, it is information generated by companies. In second place, the information circuit is fed back. A problem of informative independence becomes created, particularly serious in the case of the banks, which are very were as creditors. And in a third place, some informative biases are manifested for the companies of regulated sectors which are starring the economical information in the media.

Fertility discourse in parental leave policies' media coverage : a frame analysis of French-speaking Swiss press articles from 1999 to 2009

This paper analyses the media coverage of parental leave policies (parental and paternity leaves) in Swiss French-speaking press articles from 1999 to 2009. Switzerland is one of the rare European countries which has no statutory parental or paternity leave. The aim is to describe the mediatisation of these policies and to analyse the arguments in favour and against their implementation. We investigate the status of a fertility frame - the mobilisation of discourse relating to fertility issues - among the various arguments used to justify or reject parental leave policies. We proceed with a content analysis of 579 press articles, as well as a frame analysis on a subset in which parental leave policies are the central theme (N=206). Results show that paternity leave is the predominant public issue addressed in the dataset. A mediatisation peak was reached in 2007, following an initiative of a member of the Federal executive to implement a short paternity leave. Parental leave policies are predominantly represented in a positive light. The main positive frame is economic, in which leaves are represented as serving the interests of companies. Involved fatherhood and gender equality are also frequently mentioned as positive frames. The fertility frame is only moderately used in articles covering Swiss news on paternity leaves. Conversely, the fertility frame is largely mobilised in articles covering parental leave in other countries. We discuss some interpretations of this discrepancy and suggest future avenues of research on parental leave policies in Switzerland.

Pieces of Iowa’s Past, April 26, 2012

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. April 26, 2012 THIS WEEK: The Ed Sullivan Show is Broadcast from the USS Iowa BACKGROUND: The Ed Sullivan Show On July 4, 1954, The Ed Sullivan Show was filmed aboard the battleship U.S.S. Iowa, which was docked in the Hudson River. The Ed Sullivan Show, then called Toast of the Town, was in its seventh season. Sullivan featured many celebrities on his show over the years. During this particular show, musical comedy star Dolores Gray was featured along with Bill Kenny of the group the Ink Spots. The Step Brothers were the featured dancers. Les Marcellis led an acrobat performance, Jay Marshall provided a stand-up comedy routine, and Eileen O’Dare performed as an acrobatic dancer surrounded by the navy audience. Sullivan spoke with navy Captain Wayne Loud, who then presented Sullivan with a caricature of Sullivan drawn by famed media layout artist Herb Hazelton, who also appeared.

The Limits of Issue Ownership Dynamics : The Constraining Effect of Party Preference

Issue ownership theory argues that when a voter considers a party to be the most competent amongst others to deal with an issue (that is, the party "owns" the issue), chances are the voter will vote for that party. Recent work has shown that perceptions of issue ownership are dynamic: they are affected by the media coverage of party messages. However, based on the broad literature on partisan bias, we predict that parties' efforts to change issue ownership perceptions will have a difficult time breaching the perceptual screen created by a voter's party preference. Using two separate experiments with a similar design we show that the effect of partisan issue messages on issue competence is moderated by party preference. The effect of issue messages is reinforced when people already like a party, and blocked when people dislike a party.
