Final report on the Portable Weather Station, March 2012

This station was required to have air temperature, relative humidity, wind speed and direction, and pavement temperature sensors of similar quality to the traditional RWIS sensors, have an integrated solar powered battery system, and be trailer-mounted for ease of transport. The station was tested by the Iowa DOT for basic reliability and sensor performance for a month and a half in Ames, Iowa before being moved to near Osceola, Iowa in early February 2010 for further field testing and evaluation. DOT field maintenance staff was able to successfully set up the station with minimal instruction and found the station to be relatively intuitive in its installation. Air temperature, wind speed, and wind direction observations from the station were compared to a nearby RWIS station and had good agreement. Pavement temperature readings were compared to sites within 40 miles of the station, and the readings correlated. The station has had good reliability.

Final Report on the Portable Computerized Assessments of Sleepy Drivers in Operational Environments, June 29, 2011

Excessive daytime sleepiness underpins a large number of the reported motor vehicle crashes. Fair and accurate field measures are needed to identify at-risk drivers who have been identified as potentially driving in a sleep deprived state on the basis of erratic driving behavior. The purpose of this research study was to evaluate a set of cognitive tests that can assist Motor Vehicle Enforcement Officers on duty in identifying drivers who may be engaged in sleep impaired driving. Currently no gold standard test exists to judge sleepiness in the field. Previous research has shown that Psychomotor Vigilance Task (PVT) is sensitive to sleep deprivation. The first goal of the current study was to evaluate whether computerized tests of attention and memory, more brief than PVT, would be as sensitive to sleepiness effects. The second goal of the study was to evaluate whether objective and subjective indices of acute and cumulative sleepiness predicted cognitive performance. Findings showed that sleepiness effects were detected in three out of six tasks. Furthermore, PVT was the only task that showed a consistent slowing of both ‘best’, i.e. minimum, and ‘typical’ responses, median RT due to sleepiness. However, PVT failed to show significant associations with objective measures of sleep deprivation (number of hours awake). The findings indicate that sleepiness tests in the field have significant limitations. The findings clearly show that it will not be possible to set absolute performance thresholds to identify sleep-impaired drivers based on cognitive performance on any test. Cooperation with industry to adjust work and rest cycles, and incentives to comply with those regulations will be critical components of a broad policy to prevent sleepy truck drivers from getting on the road.

Pourquoi et comment le stress au travail est dangereux pour la santé

Six salariés sur dix ont un travail stressant. Comment fonctionne le stress ? Quels sont ses effets ? Dominique Chouanière présente l'état des connaissances scientifiques. Elle souligne qu'il faut développer la prévention à la source en identifiant les facteurs collectifs liés à l'organisation du travail.

La Cova de la Mallada (Perelló): Estudio lítico y reconstrucción paleoecológica de un yacimiento del Paleolítico Superior Final

En este artículo pretendemos dar a conocer los últimos resultados obtenidos a partir del estudio en profundidad de la industria lítica y de la fauna del yacimiento tarraconense de la Mallada (Perelló); ello nos ayudará a situarlo cronológicamente en los inicios el Magdaleniense Superior Mediterráneo.

Tourism Study Committee : final report, 1993

This is the final report of the Tourism Study Committee established by the Legislative Council to review state tourism programs to determine their ability to attract private participation, involve the tourism industry, and increase instate and out-of-state travel to Iowa tourism sites and to seek tourism industry input on private tourism efforts.

Arquitectura domèstica al Bronze Final i Primera Edat del Ferro a Catalunya: habitacions construïdes amb materials duradors: estat de la qüestió

El present treball es proposa l'estudi fonnal de I'habitat construtt amb materials duradors a Catalunya durant el Bronze Final i la Primera Edat del Ferro, i se centra en l'aninisi dels materials i tecniques de construcció emprats, així com en l' estructura de la casa (planta, dimensions, superfície). Els elements definidors d'aquests habitacles en els períodes estudiats consisteixen en l'ús sistematic de la pedra i la terra com a materials de construcció i la disposició d'habitacions de planta rectangular compartint parets mitgeres, amb poca compartimentació interna i pocs agenc¡:aments al seu interior (llar, forn, banquetes). Les dimensions maximes d'aquestes habitacions no superen, per nonna general, els 20 metres quadrats. La unifonnitat d'aquestes construccions, unida a la poca compartimentació de l'espai, suggereix que ens trobem davant una arquitectura poc especialitzada, que podria correspondre a una societat amb una organització socio-política poc complexa.

O usuário final da busca informatizada: avaliação da capacitação no acesso a bases de dados em biblioteca acadêmica

Avalia os resultados da capacitação de usuários em buscas informatizadas, por meio do Curso de Acesso às Bases em cd-rom Medline e Lilacs, modalidade do Programa Educativo da Biblioteca/CIR da Faculdade de Saúde Publica da USP, oferecido a docentes e alunos da pós-graduação em saúde pública. O universo de estudo foi constituído de 92 participantes entre 1993 e 1995. Os resultados mostraram que, após a participação no Curso, 65,2% deles conseguiram autonomia no uso das bases de dados, 15,2% solicitaram buscas intermediadas pelo bibliotecário, bem como 19,6% não realizaram forma alguma de busca nas bases da Biblioteca. A intermediação dos bibliotecários foi solicitada por motivos como: pouca familiaridade com as bases, dificuldade em lidar com tecnologia, confiança na busca realizada pelo bibliotecário e falta de tempo para buscas. O egresso do curso que não realizou busca informatizada alegou não ter tido necessidade de fazê-lo no período estudado.
