Apprendre dans l'urgence

Nous avons effectué une étude dans le but d'investiger les stratégies utilisées par les ambulanciers pour préserver leur santé. Parmi les stratégies que nous avons identifiées, celles contribuant au maintien et au développement des compétences nous ont semblé particulièrement intéressantes car elles permettent de réduire le stress lié à la peur de l'erreur. Elles permettent aussi aux ambulanciers "d'apprivoiser l'urgence" en leur donnant la possibilité de jouer un rôle actif face aux difficultés rencontrées. Nous présentons quelques-unes de ces stratégies dans cet article.

Factors associated with healthcare professionals' intent to stay in hospital: a comparison across five occupational categories.

OBJECTIVE: To identify factors associated with intent to stay in hospital among five different categories of healthcare professionals using an adapted version of the conceptual model of intent to stay (CMIS). DESIGN: A cross-sectional survey targeting Lausanne University Hospital employees performed in the fall of 2011. Multigroup structural equation modeling was used to test the adapted CMIS model among professional groups. Measures Satisfaction, self-fulfillment, workload, working conditions, burnout, overall job satisfaction, institutional identification and intent to stay. PARTICIPANTS: Surveys of 3364 respondents: 494 physicians, 1228 nurses, 509 laboratory technicians, 935 administrative staff and 198 psycho-social workers. RESULTS: For all professional categories, self-fulfillment increased intent to stay (all β > 0.14, P < 0.05). Burnout decreased intent to stay by weakening job satisfaction (β < -0.23 and β > 0.22, P < 0.05). Some factors were associated with specific professional categories: workload was associated with nurses' intent to stay (β = -0.15), and physicians' institutional identification mitigated the effect of burnout on intent to stay (β = -0.15 and β = 0.19). CONCLUSION: Respondents' intent to stay in a position depended both on global and profession-specific factors. The identification of these factors may help in mapping interventions and retention plans at both a hospital level and professional groups' level.

Liquid and solid scintillation: principles and applications

Scintillation counting is one of the most important developments in the application of radioisotopes to procedures needed by scientists, physicians, engineers, and technicians from many diverse discipline for the detection and quantitative measurement of radioactivity. In fact, Scintillation is the most sensitive and versatile technique for the detection and quantification ofradioactivity. Particularly, Solid and Liquid scintillation measurement are,nowadays, standard laboratory methods in the life-sciences for measuringradiation from gamma- and beta-emitting nuclides, respectively. Thismethodology is used routinely in the vast majority of diagnostic and/or researchlaboratories from those of biochemistry and biology to clinical departments.

Sieve Analysis of Combined Aggregate Samples by Different Test Methods, MLR-84-05, 1982

This past winter the sieve analysis of combined aggregate was investigated. This study was given No. 26 by the Central Laboratory. The purpose of this work was to try and develop a sieve analysis procedure for combined aggregate which is less time consuming and has the same accuracy as the method described in I.M. 304. In an attempt to use a variety of aggregates for this investigation, a request was made to each District Materials Office to obtain at least 3 different combined aggregate samples in their respective districts. At the same time it was also requested that the field technician test these samples, prior to submitting them to the Central Laboratory. The field technician was instructed to test each sample as described in method I.M. 304 and also by a modified AASHTO T27 method which will be identified in the report as Method A. The modified AASHTO Method A was identical to T27 with the exception that a smaller sample is used for testing. The field technicians submitted the samples, test results and also comments regarding the modified AASHTO procedure. The general comments of the modified AASHTO procedure were: The method was much simpler to follow; however, it took about the same amount of time so there was no real advantage. After reviewing AASHTO T27, T164, I.M. 304 and Report No. FHWA-RD-77-53 another test method was purposed. Report No. FHWA-RD-77-53 is a report prepared by FHWA from data they gathered concerning control practices and shortcut or alternative test methods for aggregate gradation. A second test method was developed which also was very similar to AASHTO T27, The test procedure for this method is attached and is identified as Method B. The following is a summary of test results submitted by the Field Technicians and obtained by the aggregate section of the Central Laboratory.

A European survey on current practices in epilepsy monitoring units and implications for patients' safety.

OBJECTIVE: This study aimed to survey current practices in European epilepsy monitoring units (EMUs) with emphasis on safety issues. METHODS: A 37-item questionnaire investigating characteristics and organization of EMUs, including measures for prevention and management of seizure-related serious adverse events (SAEs), was distributed to all identified European EMUs plus one located in Israel (N=150). RESULTS: Forty-eight (32%) EMUs, located in 18 countries, completed the questionnaire. Epilepsy monitoring unit beds are 1-2 in 43%, 3-4 in 34%, and 5-6 in 19% of EMUs; staff physicians are 1-2 in 32%, 3-4 in 34%, and 5-6 in 19% of EMUs. Personnel operating in EMUs include epileptologists (in 69% of EMUs), clinical neurophysiologists trained in epilepsy (in 46% of EMUs), child neurologists (in 35% of EMUs), neurology and clinical neurophysiology residents (in 46% and in 8% of EMUs, respectively), and neurologists not trained in epilepsy (in 27% of EMUs). In 20% of EMUs, patients' observation is only intermittent or during the daytime and primarily carried out by neurophysiology technicians and/or nurses (in 71% of EMUs) or by patients' relatives (in 40% of EMUs). Automatic detection systems for seizures are used in 15%, for body movements in 8%, for oxygen desaturation in 33%, and for ECG abnormalities in 17% of EMUs. Protocols for management of acute seizures are lacking in 27%, of status epilepticus in 21%, and of postictal psychoses in 87% of EMUs. Injury prevention consists of bed protections in 96% of EMUs, whereas antisuffocation pillows are employed in 21%, and environmental protections in monitoring rooms and in bathrooms are implemented in 38% and in 25% of EMUs, respectively. The most common SAEs were status epilepticus reported by 79%, injuries by 73%, and postictal psychoses by 67% of EMUs. CONCLUSIONS: All EMUs have faced different types of SAEs. Wide variation in practice patterns and lack of protocols and of precautions to ensure patients' safety might promote the occurrence and severity of SAEs. Our findings highlight the need for standardized and shared protocols for an effective and safe management of patients in EMUs.

A proposal to establish indicators for the evaluation of municipal councils' socio-cultural policies

How can municipal sociocultural policies stimulate and promote community empowerment, civic creativity or social cohesion? What objectives should be proposed at the municipal level to promote processes of sociocultural community development? How can we identify local needs in order to stimulate community development processes? In response to these questions, our paper proposes a creative solution: indicators to evaluate sociocultural policies. The proposal will enable us to obtain information about our own reality and, at the same time, contribute to producing changes and to outlining possible de intervention strategies for local administrations. The proposal describes a system of creative, flexible and rigourous indicators intended for municipal technicians and politicians interested in evaluating their sociocultural actions and strategies. We present the result of a research process whose methods included validation of the indicators by experts and technicians in or related to sociocultural community development, and the application of this system based on a case study of a Spanish municipality. Among the proposed indicators specific consideration is given to the support of local creators and the promotion of civic creativity, as well as the use, the creation and the articulation of sociocultural activities as strategies to contribute to cultural and civic diversity

Inclusion and empowerment in public art and urban design

To involve citizens in developing the processes of city making is an objective that occupies part of the agenda of political parties in the context of the necessary renewal in representative democracy. This paper aims to provide some answers to the following questions: Is it possible to overcome the participatory processes based exclusively on the consultation? Is it possible to"train" residents to take an active role in decision-making? How can we manage, proactively, the relationship between public actors, technicians and politicians, in a participatory process? We analyse the process development for creating the Wall of Remembrance in the Barcelona neighbourhood of Baró de Viver, a work of public art, created and produced by its neighbours, in the context of a long participatory process focused on changing the image of the neighbourhood and the improvement of public space. This result and this process have been possible in a given context of cooperation among neighbours, local government and the research team (CR-Polis, Art, City, Society at the University of Barcelona). The development of a creative process of citizen participation between 2004 and 2011 made possible the direct management of decision making by the residents on the field of the design of public space in the neighbourhood. However, the material results of the process does not overshadow the great achievement of the project: the inclusion of a neighbourhood in taking informed decisions because of their empowerment in public space design and management of their remembrances.

Soil quality assessment through a multi-approach analysis in soils of abandoned terraced land in NE Spain

The abandonment of agricultural land in mountainous areas has been an outstanding problem along the last century and has captured the attention of scientists, technicians and administrations, for the dramatic consequences sometimes occurred due to soil instability, steep slopes, rainfall regimes and wildfires. Hidromorfological and pedological alterations causing exceptional floods and accelerated erosion processes has therefore been studied, identifying the cause in the loss of landscape heterogeneity. Through the disappearance of agricultural works and drainage maintenance, slope stability has resulted severely affected. The mechanization of agriculture has caused the displacement of vines, olives and corks trees cultivation in terraced areas along the Mediterranean catchment towards more economically suitable areas. On the one hand, land use and management changes have implicated sociological changes as well, transforming areas inhabited by agricultural communities into deserted areas where the colonization of disorganized spontaneous vegetation has buried a valuable rural patrimony. On the other hand, lacking of planning and management of the abandoned areas has produced badlands and infertile soils due to wildfire and high erosion rates strongly degrading the whole ecosystems. In other cases, after land abandonment a process of soil regeneration has been recorded. Investigations have been conducted in a part of NE Spain where extended areas of terraced soils previously cultivated have been abandoned in the last century. The selected environments were semi-abandoned vineyards, semi-abandoned olive groves, abandoned stands of cork trees, abandoned stands of pine trees, scrubland of Cistaceaea, scrubland of Ericaceaea, and pasture. The research work was focused on the study of most relevant physical, chemical and biological soil properties, as well as runoff and erosion under soils with different plant cover to establish the abandonment effect on soil quality, due to the peculiarity and vulnerability of these soils with a much reduced depth. The period of observation was carried out from autumn 2009 to autumn 2010. The sediment concentration of soil erosion under vines was recorded as 34.52 g/l while under pasture it was 4.66 g/l. In addition, the soil under vines showed the least amount of organic matter, which was 12 times lower than all other soil environments. The carbon dioxide (CO2) and total glomalin (TG) ratio to soil organic carbon (SOC) in this soil was 0.11 and 0.31 respectively. However, the soil under pasture contained a higher amount of organic matter and showed that the CO2 and TG ratio to SOC was 0.02 and 0.11 respectively indicating that the soil under pasture better preserves the soil carbon pool. A similar trend was found in the intermediate soils in the sequence of land use change and abandonment. Soil structural stability increased in the two soil fractions investigated (0.25-2.00 mm, 2.0-5.6 mm) especially in those soils that did not undergo periodical perturbations like wildfires. Soil quality indexes were obtained by using relevant physical and chemical soil parameters. Factor analysis carried out to study the relationship between all soil parameters allowed to related variables and environments and identify those areas that better contribute to soil quality towards others that may need more attention to avoid further degradation processes

Recerca avaluativa sobre el programa “LÍMITS”

Des de la comunitat científica s’ha posat de manifest la necessitat d’avaluar els programes d’intervenció per a la millora de la parentalitat, especialment en el context de la infància i adolescència en risc. En aquesta recerca es presenten els resultats de l’avaluació del programa Límits aportant evidències d’eficàcia i efectivitat, que permeten identificar i descriure les seves fortaleses, així com també aquells elements que poden ser objecte de millora. El programa Límits és una proposta estructurada d’intervenció preventiva de caire selectiu amb grups de famílies de joves d’entre 14 i 18 anys que passen pel circuit de la justícia juvenil. El programa ha estat funcionant des del 2007, en diverses edicions, a tot el territori català aplegant una experiència i trajectòria remarcable que ha incidit en 351 persones i 245 famílies. El programa consta de vuit sessions en grup d’entre dotze i quinze participants, dinamitzat per dos monitors, en les que es treballen diferents estratègies a partir de l’abordatge de continguts relacionats amb les relacions i els lligams, la comunicació, els conflictes, l’establiment de normes i la disciplina. Per dur a terme l’avaluació del programa Límits s’ha partit d’un disseny quasi-experimental, pretest–postest aplicat a un grup programa (GP) i a grup col·laborador (GC) i de manera diferida (dos mesos després de la seva finalització) només al GP per constatar si s’han assolit els resultats previstos. Quan s’analitza l’evolució del GP s’observen millores en les habilitats d’autocontrol de les emocions, el reforç positiu i les relacions familiars. Tanmateix, des del punt de vista de les famílies no s’han observat canvis significatius en la millora de la percepció d’auto eficàcia del rol parental respecte el GC abans i després del programa. La percepció majoritària és que els objectius que planteja el programa són excessivament ambiciosos i en conseqüència, difícilment assolibles. Els responsables consideren que, en alguns casos, el perfil de famílies derivades al programa no és el més adequat perquè presenten problemàtiques molt més agudes a les desitjables per aquest tipus d’intervenció. Com a punts forts, es destaca que el programa és útil als ulls dels responsables i tècnics perquè genera una presa de consciència del problema i de la necessitat de canvi per part de les famílies. Els participants diuen transferir a la vida real algunes habilitats apreses especialment la comunicació i millora de les relacions familiars. Els tècnics aplicadors coincideixen amb la percepció de les famílies tot i declarar percentatges lleugerament inferiors. També és vist com un complement professional a la seva tasca que ajuda a fer un millor seguiment dels casos, i permet seguir treballant amb posterioritat amb les famílies.

Cuando se analiza la evolución del GP se observan mejoras en las habilidades de autocontrol de las emociones, el refuerzo positivo y las relaciones familiares. Sin embargo, desde el punto de vista de las familias no se han observado cambios significativos en la mejora de la percepción de auto eficacia del rol parental respecto al GC antes y después del programa. La percepción mayoritaria es que los objetivos que plantea el programa son excesivamente ambiciosos y en consecuencia, difícilmente alcanzables. Los responsables consideran que, en algunos casos, el perfil de familias derivadas al programa no es el más adecuado puesto que presenten problemáticas mucho más agudas a las deseables para este tipo de intervención. Como puntos fuertes, se destaca que el programa es útil a los ojos de los responsables y técnicos porque genera una toma de conciencia del problema y de la necesidad de cambio por parte de las familias. Los participantes dicen transferir a la vida real algunas habilidades aprendidas, especialmente la comunicación y mejora de las relaciones familiares. Los técnicos aplicadores coinciden con la percepción de las familias, a pesar de declarar porcentajes ligeramente inferiores. También es visto como un complemento profesional a su tarea que ayuda a hacer un mejor seguimiento de los casos, y permite seguir trabajando con posterioridad con las familias.
