Implementation of a medical command and control team in Switzerland.

In case of a major incident or disaster, the advance medical rescue command needs to manage several essential tasks simultaneously. These include the rapid deployment of ambulance, police, fire and evacuation services, and their coordinated activity, as well as triage and emergency medical care on site. The structure of such a medical rescue command is crucial for the successful outcome of medical evacuation at major incidents. However, little data has been published on the nature and structure of the command itself. This study presents a flexible approach to command structure, with two command heads: one emergency physician and one experienced paramedic. This approach is especially suitable for Switzerland, whose federal system allows for different structures in each canton. This article examines the development of these structures and their efficiency, adaptability and limitations with respect to major incident response in the French-speaking part of the country.

MAMOT: hidden Markov modeling tool.

Hidden Markov models (HMMs) are probabilistic models that are well adapted to many tasks in bioinformatics, for example, for predicting the occurrence of specific motifs in biological sequences. MAMOT is a command-line program for Unix-like operating systems, including MacOS X, that we developed to allow scientists to apply HMMs more easily in their research. One can define the architecture and initial parameters of the model in a text file and then use MAMOT for parameter optimization on example data, decoding (like predicting motif occurrence in sequences) and the production of stochastic sequences generated according to the probabilistic model. Two examples for which models are provided are coiled-coil domains in protein sequences and protein binding sites in DNA. A wealth of useful features include the use of pseudocounts, state tying and fixing of selected parameters in learning, and the inclusion of prior probabilities in decoding. AVAILABILITY: MAMOT is implemented in C++, and is distributed under the GNU General Public Licence (GPL). The software, documentation, and example model files can be found at http://bcf.isb-sib.ch/mamot

PyRate: a new program to estimate speciation and extinction rates from incomplete fossil data

Despite the advancement of phylogenetic methods to estimate speciation and extinction rates, their power can be limited under variable rates, in particular for clades with high extinction rates and small number of extant species. Fossil data can provide a powerful alternative source of information to investigate diversification processes. Here, we present PyRate, a computer program to estimate speciation and extinction rates and their temporal dynamics from fossil occurrence data. The rates are inferred in a Bayesian framework and are comparable to those estimated from phylogenetic trees. We describe how PyRate can be used to explore different models of diversification. In addition to the diversification rates, it provides estimates of the parameters of the preservation process (fossilization and sampling) and the times of speciation and extinction of each species in the data set. Moreover, we develop a new birth-death model to correlate the variation of speciation/extinction rates with changes of a continuous trait. Finally, we demonstrate the use of Bayes factors for model selection and show how the posterior estimates of a PyRate analysis can be used to generate calibration densities for Bayesian molecular clock analysis. PyRate is an open-source command-line Python program available at http://sourceforge.net/projects/pyrate/.

Management of major accidents with on-site 144 dispatcher

Introduction: An excellent coordination between firefighters, policemen and medical rescue is the key to success in the management of major accidents. In order to improve and assist the medical teams engaged on site, the Swiss "medical command and control system" for rescue operations is based on a binomial set up involving one head emergency doctor and one head rescue paramedic, both trained in disaster medicine. We have recently experimented an innovative on-site "medical command and control system", based on the binomial team, supported by a dedicated 144 dispatcher. Methods: A major road traffic accident took place on the highway between Lausanne and Vevey on April 9th 2008. We have retrospectively collected all data concerning the victims as well as the logistics and dedicated structures, reported by the 144, the Hospitals, the Authority of the State and the Police and Fire Departments. Results: The 72-car pileup caused one death and 26 slightly injured patients. The management on the accident site was organized around a tripartite system, gathering together the medical command and control team with the police and fire departments. On the medical side, 16 ambulances, 2 medical response teams (SMUR), the Rega crew and the medical command and control team were dispatched by the 144. On that occasion an advanced medical command car equipped with communication devices and staffed with a 144 dispatcher was also engaged, allowing efficient medical regulation directly from the site. Discussion: The specific skills of one doctor and one paramedic both trained for disaster's management proved to be perfectly complementary. The presence of a dispatcher on site with a medical command car also proved to be useful, improving orders transmission from the medical command team to all other on- and off-site partners. It relieved the need of repeated back-and-forth communication with the 144, allowing both paramedic and doctor to focus on strategy and tactics rather than communication and logistics.

Exposition des enfants à la fumée passive: le point sur des campagnes de sensibilisation

Enfants de moins de 10 ans fumant passivement 14 cigarettes ! D'avril 2010 à avril 2011, l'exposition de 148 enfants (81 garçons et 67 filles) a été testée: 10 enfants de moins d'un an, 25 de 1 à 5 ans, 19 de 5 à 10 ans, 30 de 10 à 15 ans et 64 de 15 à 18 ans. 10 d'entre eux sont des fumeurs et la plus jeune de 14 ans fume 10 cigarettes par jour. Leurs parents, ou parfois des jeunes eux-mêmes, ont commandé de manière volontaire, via les sites Internet des CIPRET Valais, Vaud et Genève, un badge MoNIC gratuit. Les résultats quant à l'exposition de ces enfants interpellent et méritent l'attention.Pour l'ensemble des enfants, la concentration moyenne de nicotine dans leur environnement intérieur mesurée via les dispositifs MoNIC est de 0,5 mg/m3, avec des maximums pouvant aller jusqu'à 21 mg/m3. Pour le collectif d'enfants âgés de moins de 10 ans (26 garçons et 28 filles; tous non-fumeurs), la concentration de nicotine n'est pas négligeable (moyenne 0,069 mg/m3, min 0, max 0,583 mg/m3). En convertissant ce résultat en équivalent de cigarettes inhalées passivement, nous obtenons des chiffres allant de 0 à 14 cigarettes par jour* avec une moyenne se situant à 1.6 cig/j. Encore plus surprenant, les enfants de moins d'un an (4 garçons et 6 filles) inhalent passivement, dans le cadre familial, en moyenne 1 cigarette (min 0, max 2.2). Pour les deux autres collectifs: 10-15 ans et 15-18 ans, les valeurs maximales avoisinent les 22 cigarettes. Notons cependant que ce résultat est influencé, ce qui n'est pas le cas des enfants plus jeunes, par le fait que ces jeunes sont également parfois des fumeurs actifs.* Quand la durée d'exposition dépassait 1 jour (8 heures), le nombre d'heures a toujours été divisé par 8 heures. Le résultat obtenu donne l'équivalent de cigarettes fumées passivement en huit heures. Il s'agit de ce fait d'une moyenne, ce qui veut dire que durant cette période les enfants ont pu être exposés irrégulièrement à des valeurs supérieures ou inférieures à cette moyenne. [Auteurs]

Automated scoring of AFLPs using RawGeno v 2.0, a free R CRAN library.

Amplified Fragment Length Polymorphisms (AFLPs) are a cheap and efficient protocol for generating large sets of genetic markers. This technique has become increasingly used during the last decade in various fields of biology, including population genomics, phylogeography, and genome mapping. Here, we present RawGeno, an R library dedicated to the automated scoring of AFLPs (i.e., the coding of electropherogram signals into ready-to-use datasets). Our program includes a complete suite of tools for binning, editing, visualizing, and exporting results obtained from AFLP experiments. RawGeno can either be used with command lines and program analysis routines or through a user-friendly graphical user interface. We describe the whole RawGeno pipeline along with recommendations for (a) setting the analysis of electropherograms in combination with PeakScanner, a program freely distributed by Applied Biosystems; (b) performing quality checks; (c) defining bins and proceeding to scoring; (d) filtering nonoptimal bins; and (e) exporting results in different formats.

Etude de mentions manuscrites apposées dans des conditions non conventionnelles (dans le cadre des articles 322-1 à 322-4 du nouveau code pénal français)

Résumé Les experts forensiques en documents peuvent être confrontés à des écritures réalisées en conditions non conventionnelles. Ces circonstances atypiques pourraient être à l'origine d'une plus grande variabilité de la forme de l'écriture, en particulier lorsque des positions à priori inhabituelles du corps et / ou du support sont impliquées. En effet, en dépit de son aspect stéréotypé /standardisé évident, résultat d'un apprentissage par un modèle, notre écriture est caractérisée par une variabilité intrinsèque de la forme, qui évolue au cours du temps et qui, dans sa dimension qualitative, confère à l'écriture son caractère individuel. En d'autres termes, nous n'écrivons jamais deux fois de la même façon. Cette variabilité intraindividuelle (ou intra-variabilité) observée en condition conventionnelle, c'est-à-dire assis devant un support horizontal, pourrait augmenter en conditions non conventionnelles, par exemple dans une position inconfortable. Cela pourrait rendre plus difficile l'identification d'écrits apposés dans une condition non conventionnelle ou inconnue. Ne pas connaître les circonstances d'apposition d'une mention manuscrite ou ne pas s'interroger sur ces dernières, pourrait conduire l'expert à faire des erreurs d'appréciation. Et le simple fait d'étudier une trace sur laquelle le corps peut exercer une influence fait de l'expertise en écriture une spécialité qui se distingue des autres disciplines forensiques. En cela, la trace écrite diffère des autres types de traces "inanimées" (physiques, chimiques, bigchimiques) considérées comme invariables (mais potentiellement sensibles à d'autres phénomènes tels que la température, la pression atmosphérique...). En effet, le mouvement d'écriture étant commandé et contrôlé par le cerveau, cela lui confère une certaine variabilité. Il est donc assez logique de penser que la connaissance des mécanismes neuroscientifiques à l'origine de ce mouvement facilitera la compréhension des phénomènes observés d'un point de vue forensique. Deux expériences ont été menées afin de comparer les performances de sujets écrivant dans différentes conditions (conventionnelle vs. non conventionnelles). Les résultats ont montré que cinq des sept conditions non conventionnelles n'avaient pas d'impact significatif sur la variabilité d'écriture. L'ensemble des résultats fournit aux experts forensiques des pistes leur permettant de mieux appréhender les écritures rédigées dans des conditions inhabituelles.

How to operate a university institute as a radiological emergency service?

The Institute of Radiation Physics (IRA) is attached to the Department of Medical Radiology at the Vaud University Hospital Center (CHUV) in Lausanne. The Institute's main tasks are strongly linked to the medical activities of the Department: radiotherapy, radiodiagnostics, interventional radiology and nuclear medicine. The Institute also works in the fields of operational radiation protection, radiation metrology and radioecology. In the case of an accident involving radioactive materials, the emergency services are able to call on the assistance of radiation protection specialists. In order to avoid having to create and maintain a specific structure, both burdensome and rarely needed, Switzerland decided to unite all existing emergency services for such events. Thus, the IRA was invited to participate in this network. The challenge is therefore to integrate a university structure, used to academic collaborations and the scientific approach, to an interventional organization accustomed to strict policies, a military-style command structure and "drilled" procedures. The IRA's solution entails mobilizing existing resources and the expertise developed through professional experience. The main asset of this solution is that it involves the participation of committed collaborators who remain in a familiar environment, and are able to use proven materials and mastered procedures, even if the atmosphere of an accident situation differs greatly from regular laboratory routines. However, this solution requires both a commitment to education and training in emergency situations, and a commitment in terms of discipline by each collaborator in order to be integrated into a response plan supervised by an operational command center.

Évaluation de la politique de formation de la police. Enquête par questionnaire et entretiens approfondis auprès des policiers/ères récemment assermenté-e-s

Ce rapport de recherche a été commandé par la Commission externe d'évaluation des politiques publiques du Canton de Genève (Suisse) dans le cadre d'une évaluation de la politique de formation de la police dans ce canton. L'étude montre que, d'une manière générale, les policiers/ères récemment assermenté-e-s jugent positivement leur formation, en particulier certains éléments du dispositif pédagogique (durée de la formation, charge de travail, formateurs/trices) et se sentent bien préparé-e-s à gérer les contacts avec leurs différents publics (en particulier les personnes agressives et les victimes de violences domestiques). Néanmoins, la plupart des policiers/ères interrogé-e-s perçoivent le travail effectué au sein des services comme étant éloigné des prescriptions scolaires. Ils estiment que ces dernières ne sont pas celles qui sont appliquées par leurs collègues expérimenté-e-s. Les matières physico-techniques sont, d'une manière générale, considérées comme plus utiles et plus importantes que les matières relationnelles. Dans cet ordre d'idée, un certain nombre de policiers/ères réclament moins de psychologie. Il s'agit cependant de la matière relationnelle à propos de laquelle les jugements sont les plus nuancés, en particulier à propos des savoirs permettant de gérer les personnes présentant des troubles mentaux, d'améliorer la communication et de gérer les conflits (au détriment de ceux visant à l'introspection). Les enseignements de police de proximité ont quant à eux tendance à être associés à une spécialisation propre à la gendarmerie et inutile pour les nouveaux/elles entrant-e-s, en particulier les inspecteurs/trices. L'éthique et les droits de l'Homme concentrent par contre les jugements négatifs : ces cours sont perçus comme diffusant des « bonnes paroles » prêchées par des formateurs/trices extérieurs à la profession (si ce n'est réellement, du moins symboliquement), éloignées de la réalité du métier et échouant à combattre les préjugés, en particulier ceux basés sur l'origine ethnico-nationale. L'étude montre en outre que les compétences relationnelles et les rapports aux différents publics sont centrales dans les appréciations portées sur l'adéquation entre formation et pratique. À ce sujet, ont été repérés néanmoins des points qui posent problèmes (aux yeux des policiers/ères interrogé-e-s ou à nos yeux) : peu de réflexivité en ce qui concerne les risques associés au «délit de faciès», problèmes avec les « maghrébins » et les jeunes en groupe (liés en particulier à la remise en cause de l'autorité policière), imprévisibilité des consommateurs/trices de drogue et vision pessimiste (parfois très peu empathique) de la toxicomanie, sentiment de difficulté et d'inconfort associé aux tâches visant à prendre en charge la souffrance d'autrui, relégation de la plupart des situations de violence domestique au rang de tâches indues, difficultés associées aux contacts avec les personnes atteintes de maladies psychiques graves, et la mention en priorité des cours de TTI pour la gestion des personnes agressives (au détriment des matières relationnelles).

CoDiab-VD: protocol of a prospective population-based cohort study on diabetes care in Switzerland.

BACKGROUND: Diabetes represents an increasing health burden worldwide. In 2010, the Public Health Department of the canton of Vaud (Switzerland) launched a regional diabetes programme entitled "Programme cantonal Diabète" (PcD), with the objectives to both decrease the incidence of diabetes and improve care for patients with diabetes. The cohort entitled CoDiab-VD emerged from that programme. It specifically aimed at following quality of diabetes care over time, at evaluating the coverage of the PcD within this canton and at assessing the impact of the PcD on care of patients with diabetes. METHODS/DESIGN: The cohort CoDiab-VD is a prospective population-based cohort study. Patients with diabetes were recruited in two waves (autumn 2011--summer 2012) through community pharmacies. Eligible participants were non-institutionalised adult patients (≥ 18 years) with diabetes diagnosed for at least one year, residing in the canton of Vaud and coming to a participating pharmacy with a diabetes-related prescription. Women with gestational diabetes, people with obvious cognitive impairment or insufficient command of French were not eligible. Self-reported data collected, included the following primary outcomes: processes-of-care indicators (annual checks) and outcomes of care such as HbA1C, (health-related) quality of life measures (Short Form-12 Health Survey--SF-12, Audit of Diabetes-Dependent Quality of Life 19--ADDQoL) and Patient Assessment of Chronic Illness Care (PACIC). Data on diabetes, health status, healthcare utilisation, health behaviour, self-management activities and support, knowledge of, or participation to, campaigns/activities proposed by the PcD, and socio-demographics were also obtained. For consenting participants, physicians provided few additional pieces of information about processes and laboratory results. Participants will be followed once a year, via a mailed self-report questionnaire. The core of the follow-up questionnaires will be similar to the baseline one, with the addition of thematic modules adapting to the development of the PcD. Physicians will be contacted every 2 years. DISCUSSION: CoDiab-VD will allow obtaining a broad picture of the care of patients with diabetes, as well as their needs regarding their chronic condition. The data will be used to evaluate the PcD and help prioritise targeted actions. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, identifier NCT01902043, July 9, 2013.

Language Ability and Motivation among Foreigners in Survey Responding

With increasing migration and linguistic diversification in many countries, survey researchers and methodologists should consider whether data provided by individuals with variable levels of command of the survey language are of the same quality. This paper examines the question of whether answers from resident foreign respondents who do not master available survey languages may suffer from problems of comprehension of survey items, especially items that are more complicated in terms of content and/or form. In addition, it addresses the extent to which motivation may affect the response quality of resident foreigners. We analyzed data from two large-scale surveys conducted in Switzerland, a country with three national languages and a burgeoning foreign population, employing a set of dependent measures of response quality, including don't know responses, extreme responding, mid-5 responding, recency effects, and straight-lining. Results show overall poorer response quality among foreigners, and indicate that both reduced language mastery and motivation among foreigners are relevant factors. This is especially true for foreign groups from countries that do not share a common language with those spoken in Switzerland. A general conclusion is that the more distant respondents are culturally and linguistically from the majority mainstream within a country, the more their data may be negatively affected. We found that more complex types of questions do generally lead to poorer response quality, but to a much lesser extent than respondent characteristics, such as nationality, command of the survey language, level of education, and age.

Interdependency management in universities: a case study

There remains uncertainty in scientific discussions regarding the governance of universities in new public management regimes in terms of who actually 'rules' in the university. Apparently, a strengthened management leadership is confronted with continuing elements of academic self-regulation and professional autonomy in knowledge production and diffusion. Organisational and academic rationales coexist in today's management of universities. This article endeavours to clarify some of the ambiguities pertaining to the coexistence of two authorities by demonstrating the working of 'interdependency management' that is taking place within universities. For this purpose, the authors have scrutinised research, teaching and recruitment policies in one Swiss university that is subject to such ambiguities. The study confirms existing research in that a command-and-control system is not applied. Policymaking in universities is instead based on a mix of negotiations in faculties that are taking place in the 'shadow of hierarchy', negotiated bargaining between faculties and leaders and occasional unilateral decisions of leaders. This mitigates latent conflicts between management and the academic community: strategic orientations of the university are generally accepted by the academic community while the academic community has influence on policy formulation and maintains defining powers over policy substance.
