L'intelligence-led policing: un cadre pertinent pour soutenir la lutte contre les incendies volontaires répétitifs

Agir efficacement contre les incendies volontaires répétitifs représente un défi de taille pour la société et la police. Nous proposons d'utiliser l'intelligence-led policing et le cycle du renseignement comme cadre à une approche permettant une gestion et un suivi global et systématique de ces événements. Mais avant de pouvoir lancer ce processus, un certain nombre de défis doit être surmonté tel que la nature non spécifique des données. Il sera alors possible de mettre en place un processus qui permettra de faire des analyses pour obtenir une vision des incendies, détecter des situations répétitives et des liens entre les événements mettant en évidence des séries. Le renseignement obtenu par l'analyse des données rassemblées peut ensuite être utilisé pour mettre en place des moyens complémentaires d'enquête ou pour prendre des mesures préventives ou répressives.

Effect of a governmentally-led physical activity program on motor skills in young children attending child care centers: a cluster randomized controlled trial.

OBJECTIVE: To assess the effect of a governmentally-led center based child care physical activity program (Youp'la Bouge) on child motor skills.Patients and methods: We conducted a single blinded cluster randomized controlled trial in 58 Swiss child care centers. Centers were randomly selected and 1:1 assigned to a control or intervention group. The intervention lasted from September 2009 to June 2010 and included training of the educators, adaptation of the child care built environment, parental involvement and daily physical activity. Motor skill was the primary outcome and body mass index (BMI), physical activity and quality of life secondary outcomes. The intervention implementation was also assessed. RESULTS: At baseline, 648 children present on the motor test day were included (age 3.3 +/- 0.6, BMI 16.3 +/- 1.3 kg/m2, 13.2% overweight, 49% girls) and 313 received the intervention. Relative to children in the control group (n = 201), children in the intervention group (n = 187) showed no significant increase in motor skills (delta of mean change (95% confidence interval: -0.2 (-0.8 to 0.3), p = 0.43) or in any of the secondary outcomes. Not all child care centers implemented all the intervention components. Within the intervention group, several predictors were positively associated with trial outcomes: 1) free-access to a movement space and parental information session for motor skills 2) highly motivated and trained educators for BMI 3) free-access to a movement space and purchase of mobile equipment for physical activity (all p < 0.05). CONCLUSION: This "real-life" physical activity program in child care centers confirms the complexity of implementing an intervention outside a study setting and identified potentially relevant predictors that could improve future programs.Trial registration: Trial registration number: clinical trials.gov NCT00967460 http://clinicaltrials.gov/ct2/show/NCT00967460.

Intelligence-led crime scene processing. Part II : Intelligence and crime scene examination.

A better integration of the information conveyed by traces within intelligence-led framework would allow forensic science to participate more intensively to security assessments through forensic intelligence (part I). In this view, the collection of data by examining crime scenes is an entire part of intelligence processes. This conception frames our proposal for a model that promotes to better use knowledge available in the organisation for driving and supporting crime scene examination. The suggested model also clarifies the uncomfortable situation of crime scene examiners who must simultaneously comply with justice needs and expectations, and serve organisations that are mostly driven by broader security objectives. It also opens new perspective for forensic science and crime scene investigation, by the proposal to follow other directions than the traditional path suggested by dominant movements in these fields.

Light-emitting diodes (LED) for domestic lighting: any risks for the eye?

Light-emitting diodes (LEDs) are taking an increasing place in the market of domestic lighting because they produce light with low energy consumption. In the EU, by 2016, no traditional incandescent light sources will be available and LEDs may become the major domestic light sources. Due to specific spectral and energetic characteristics of white LEDs as compared to other domestic light sources, some concerns have been raised regarding their safety for human health and particularly potential harmful risks for the eye. To conduct a health risk assessment on systems using LEDs, the French Agency for Food, Environmental and Occupational Health & Safety (ANSES), a public body reporting to the French Ministers for ecology, for health and for employment, has organized a task group. This group consisted physicists, lighting and metrology specialists, retinal biologist and ophthalmologist who have worked together for a year. Part of this work has comprised the evaluation of group risks of different white LEDs commercialized on the French market, according to the standards and found that some of these lights belonged to the group risk 1 or 2. This paper gives a comprehensive analysis of the potential risks of white LEDs, taking into account pre-clinical knowledge as well as epidemiologic studies and reports the French Agency's recommendations to avoid potential retinal hazards.

Intelligence-led crime scene processing. Part I : Forensic intelligence.

Forensic science is generally defined as the application of science to address questions related to the law. Too often, this view restricts the contribution of science to one single process which eventually aims at bringing individuals to court while minimising risk of miscarriage of justice. In order to go beyond this paradigm, we propose to refocus the attention towards traces themselves, as remnants of a criminal activity, and their information content. We postulate that traces contribute effectively to a wide variety of other informational processes that support decision making inmany situations. In particular, they inform actors of new policing strategies who place the treatment of information and intelligence at the centre of their systems. This contribution of forensic science to these security oriented models is still not well identified and captured. In order to create the best condition for the development of forensic intelligence, we suggest a framework that connects forensic science to intelligence-led policing (part I). Crime scene attendance and processing can be envisaged within this view. This approach gives indications abouthowto structure knowledge used by crime scene examiners in their effective practice (part II).

La diminution de l'activité du répresseur ICER dans les adipocytes est responsable de la résistance à l'insuline dirigée par le facteur CREB dans l'obésité [The decreased activity of the repressor ICER in adipocytes is responsible for insulin resistance led by factor CREB in obesity.]

Introduction: Une élévation de l'activité des facteurs de transcription CREBs dans le tissu adipeux est en partie responsable de l'insulino-résistance systémique dans l'obésité. Le facteur «Inducible cAMP early repressor» (ICER) est un répresseur transcriptionnel passif dont le niveau d'expression antagonise l'activité des CREBs. L'objectif de ce travail adipocytaire des CREBs dans l'obésité chez l'Homme et la souris. Matériels et méthodes: Du tissu adipeux blanc (TAB) a été prélevé chez des souris obèses nourries sous une diète normale et des souris obèses nourries sous un régime riche en graisses pendant 12 semaines. Des biopsies de tissu adipeux viscéral (TAV) ont été prélevées chez les sujets humains minces (BMI = 24 ± 0,5 kg/m2) et obèses (BMI > 35 kg/m2). L'expression des gènes est quantifiée par RT-PCR quantitative. L'activité des CREBs et d'ICER est mesurée par des expériences de retard sur gel. L'activité des histones déacétylases est quantifiée par dosage colorimétrique. Résultats: L'expression et l'activité d'ICER sont diminuées dans le TAB des souris obèses, hyper-glycémiques et insulino-résistantes. De même, l'activité d'ICER est réduite dans le TAV des sujets humains obèses. Cette réduction corrèle avec une augmentation de l'activité des CREBs, une réduction de l'expression de Glut4 et de l'adiponectine, à la fois chez l'Homme et la souris. La diminution de l'expression d'ICER n'est observée que dans la fraction adipocytaire du tissu adipeux. L'expression d'ICER est contrôlée par l'activité des HDACs. L'inhibition des HDACs inhibe l'expression d'ICER dans les adipocytes. L'activité totale des HDACs est réduite dans les tissus adipeux chez les souris et chez les sujets humains obèses. Conclusion: La diminution de l'activité d'ICER dans les adipocytes par une modification de l'activité des HDACs serait responsable de l'augmentation de l'activité des CREBs dans l'obésité.

First systematic chemical profiling of cocaine police seizures in Finland in the framework of an intelligence-led approach

For the first time in Finland, the chemical profiling of cocaine specimens was performed at the National Bureau of Investigation (NBI). The main goals were to determine the chemical composition of cocaine specimens sold in the Finnish market and to study the distribution networks of cocaine in order to provide intelligence related to its trafficking. An analytical methodology enabling through one single GC-MS injection the determination of the added cutting agents (adulterants and diluents), the cocaine purity and the chemical profile (based on the major and minor alkaloids) for each specimen was thus implemented and validated. The methodology was found to be efficient for the discrimination between specimens coming from the same source and specimens coming from different sources. The results highlighted the practical utility of the chemical profiling, especially for supporting the investigation through operational intelligence and improving the knowledge related to the cocaine trafficking through strategic intelligence.

The Role of Railways in Export-Led Growth: The Case of Uruguay, 1870-1913

The social saving literature has highlighted the indispensable role that railways played before 1914 in several Latin American export-oriented economies, such as Mexico, Brazil and Argentina. The article analyses the case of Uruguay, a country that, by 1914, had built one of the densest railway networks in Latin America. The article shows that, in contrast to what happened in other economies of the region, the resource saving effects of the Uruguayan railways during the first globalisation were tiny due to the small share that railway output accounted for within the country's gross domestic product (GDP). Three complementary reasons are suggested to explain that result, namely: the geographical structure of the country; its sectoral specialisation; and the small scale of the Uruguayan economy. Due to these three characteristics, Uruguay was unable to benefit from railways in the way that other export-oriented Latin American economies did during the first period of globalisation. This conclusion draws attention to the geographic-specific character of railway technology.

Mikrokontrolleriohjaus led-ryhmälle

Luonnonvarojen ehtyminen ja ympäristön saastuminen on luonut kysyntää uusille, energiaa säästäville ja ympäristöystävällisille teknologioille. Valaistuksessa tällainen teknologia on led-tekniikka. Led-tekniikalla on useita etuja verrattuna kilpaileviin tekniikoihin kuten pitkä elinikä, ympäristöystävällisyys ja mekaaninen kestävyys. Ledejä käytetään nykyään laajalti erilaisissa erikoissovelluksissa, erityisesti jos vaatimuksena on valon värillisyys. Näihin päiviin asti ledien hinta ja heikko valontuotto ovat rajoittaneet led-valaisimien yleistymistä hehkulamppujen ja muiden valaisintyyppien korvaajina. Tekniikan nopea kehittyminen on tehnyt led-tekniikasta varteenotettavan vaihtoehdon myös yleisvalaistukseen. Uusimpien valkoisten ledien valotehokkuus on 2 - 5 -kertainen hehkulamppuun verrattuna. Led-tekniikassa on vielä paljon käyttämätöntä potentiaalia, tulevaisuudessa päästäneen 10 - 15 -kertaiseen valotehokkuuteen hehkulamppuun verrattuna. Työssä suunnitellaan mikrokontrolleripohjainen ohjausjärjestelmä valkoista valoa tuottavalle led-valaisimelle, jonka värisävyä ja kirkkautta käyttäjä voi säätää. Valkoinen valo synnytetään sekoittamalla neljän erivärisen led-rivin valoa. Mikrokontrolleri ohjaa kutakin led-riviä väriensekoitusteoriaan perustuen. Mikrokontrolleriohjaus huomioi myös ledien optisten ominaisuuksien muutokset lämpötilan suhteen. Mikrokontrolleriohjauksen suorituskyky todetaan käytännön mittauksilla.

Monomer conversion of composite dental resins photoactivated by a halogen lamp and a LED: a FT-Raman spectroscopy study

Eighteen circular blocks of resins cured either by a LED or a halogen lamp (20, 40 and 60 s), had their top (T) and bottom (B) surfaces studied using a FT-Raman spectrometer. Systematic changes in the intensity of the methacrylate C=C stretching mode at 1638 cm-1 as a function of exposure duration were observed. The calculated degree of conversion (DC) ranged from 45.0% (B) to 52.0% (T) and from 49.0% (B) to 55.0% (T) for the LED and halogen lamp, respectively. LED and halogen light produced similar DC values with 40 and 60 s of irradiation.

Um fotômetro multi-led microcontrolado, portátil e de baixo custo

A microcontrolled, portable and inexpensive photometer is described. It uses six light-emitting diodes (LEDs) as radiation sources and a phototransistor as detector, as well as a microcontroller (PIC - Programmable Controller of Interruption). This device provided total autonomy to the proposed photometer, which was successfully applied to determination of Fe2+ in ferrous syrups and of seven clinical biochemical parameters. As the components are cheap (~U$30.00) and easy to find, the proposed photometer is an economical alternative for routine chemical analyses in small laboratories, for research and teaching. Being portable and microcontrolled, it allows doing field chemical analyses.
