Projektet: W7 DALARNA - Ett regionalt resurscentrum för kvinnligt entreprenörskap, jämställdhet och integration

De flesta kvinnor är enmansföretagare och driver en enskild firma, medan männen driver ett aktiebolag. I Dalarna gick det år 2006 2,7 manliga företagare på en kvinnlig, samtidigt som allt fler kvinnorna startar eget företag. I några av de kommuner som deltar i projektet W7 Dalarna har en hög andel kvinnliga företagare bland de företag som startas.Det övergripande syftet för W7 DALARNA formulerades som: ”att bygga upp en stark organisation med lokal närvaro och samordnad verksamhet.” Verksamhetens innehåll skulle inriktas på opinionsbildning, inspiration, utbildning, erfarenhetsutbyte, metodutveckling och att tillvarata synergieffekter inom projektets tre verksamhetsteman. Projektet syftadeockså till att utveckla kompetens- och kvalitetssäkring inom området affärsrådgivningoch att etablera och upprätthålla en lokal fysisk närvaro. Därutöver skulle projektet: ”verka för att Resurscentra för kvinnor skall accepteras som en aktör för lokal och regional utveckling, och fungera som en jämbördig partner i tillväxtarbetet.”

Harold Pinter, cinema e literatura : os limites da realidade

Partindo de duas questões teóricas preliminares, uma, da representação (literária e cinematográfica)do real e do imaginário, tanto no ângulo da produção como no da sua recepção e, a outra, da articulação entre formas de expressão artísticas distintas, ou seja, da interdisciplinaridade, este trabalho examina a presença do tema relativo aos limites entre realidade e fantasia no teatro, no cinema e na literatura, centrando sua atenção na obra de Harold Pinter. Consta de duas partes, cada uma com três capítulos. Na primeira, "Os pressupostos," discute-se as questões que fornecem seu substrato teórico. A segunda é dedicada ao corpus, identificando em seu título o tema investigado: "Os limites da realidade." Quanto à questão da representação, procura-se refutar "a afirmação de que a arte seja uma imitação da realidade. Uma releitura da Poética, de Aristóteles, reforçada pela opinião de diversos estudiosos da mesma, permite afirmar que a mÍmese corresponde, isto sim, a uma representação que envolve uma construção em que elementos da realidade são organizados segundo uma verdade criada pela própria obra, de acordo com critérios inerentes a ela. Além disso, através de uma leitura de Kathryn Hume, procura-se afirmar a interação sinestésica quase que permanente dos impulsos realista e da fantasiana literatura, identificando os tipos com que a fantasia se manifesta e as técnicas usadas para sua criação. A primeira parte encerra-se com um exame do relacionamento da literatura com as artes visuais e dramáticas, relações inter-disciplinares que situam este trabalho na literatura comparada.Dentre vários autores cujas obras contribuem para tal fim, destaca-se Martin Esslin, que estabelece os limitesde cada uma das artes dramáticas, identifica contatos delas com a literatura e permite, através de uma leitura de seu estudo sobre o teatro do absurdo, seja estabelecida a evolução que liga Aristóteles a Pinter. O corpus centra-se na obra de Pinterpara o teatro e para o cinema, sem limitar-se a ela,pois são também analisadas obras de outros escritores e cineastas, estabelendo-se aproximações ou contrastes entre elas. No quarto capítulo estão agrupadas obras nas quais desponta a imposição de verdades pela força fisica ou verbal. A luta pelo poder, a expulsão de elementos estranhos, dúvidas sobre a identidade e a inter-penetrablidade arte-vida caracterizam o capítulo seguinte. A ênfase temática do sexto capítulo recai sobre as limitações impostas pela condição humana. Praticamente todas as obras expressam a impossibilidade da existência de certezas absolutas e de uma perfeita distinção dos limites da realidade. Com isso, é possível afirmar não ser o objetivo da arte reproduzir a realidade. Mesmo que o fosse, tal tentativa resultaria infrutífera devido às limitações humanas.

Ensaios acelerados de pavimentos para avaliação de desempenho de recapeamentos asfálticos

Esta dissertação apresenta uma avaliação da eficiência de um recapeamento constituído por mistura de asfalto-borracha (processo via-úmida), no retardamento de reflexão de trincas, através da técnica de ensaios acelerados. Para a realização do estudo foi construído um pavimento experimental com camada final de terraplenagem de argila arenosa de comportamento laterítico (50 cm), base de brita graduada (30 cm), camada de concreto asfáltico trincado (4 cm) e camada de recapeamento em asfalto-borracha (5 cm). O simulador de tráfego DAER/UFRGS aplicou aproximadamente 513.000 ciclos de carga de eixo de 100 kN. Ao longo do experimento o desempenho do pavimento foi acompanhado, com ênfase no surgimento de trincas. A evolução da condição estrutural do pavimento foi monitorada através das medidas de deflexões e dados de instrumentação (tensões e deformações). O registro da evolução da condição funcional do pavimento foi feito através do levantamento de afundamento de trilha de roda, e macro e micro textura. Com a finalidade de comparar o desempenho do recapeamento em asfalto-borracha com os de outros recapeamentos convencionais previamente ensaiados, desenvolveu-se um procedimento para correção de temperaturas. Constatou-se que o emprego de asfalto-borracha retardou em cinco vezes o surgimento de trincas. Assim, o nível de severidade do trincamento igual a 100 cm/m2 ocorreu no recapeamento em asfalto-borracha após 340.000 solicitações (100 kN), enquanto no recapeamento em asfalto convencional tal nível de severidade foi registrado com somente 66.000 solicitações da mesma carga de eixo. Globalmente, o recapeamento em asfalto-borracha conferiu ao pavimento melhores condições funcionais e estruturais, se comparado com um recapeamento convencional da mesma espessura, executado sobre um pavimento com níveis de degradação similares.

Different responses in bulk density and saturated hydraulic conductivity to soil deformation by logging machinery on a Ferralsol under native forest

Ferralsols have high structural stability, although structural degradation has been observed to result from forest to tillage or pasture conversion. An experimental series of forest skidder passes in an east Amazonian natural forest was performed for testing the effects of mechanical stress during selective logging operations on a clay-rich Ferralsol under both dry and wet soil conditions. Distinct ruts formed up to 25 cm depth only under wet conditions. After nine passes the initially very low surface bulk density of between 0.69 and 0.80 g cm(-3) increased to 1.05 g cm(-3) in the wet soil and 0.92 g cm(-3) in the dry soil. Saturated hydraulic conductivities, initially > 250 mm h(-1), declined to a minimum of around 10 mm h(-1) in the wet soil after the first pass, and in the dry soil more gradually after nine passes. The contrasting response of bulk density and saturated hydraulic conductivity is explained by exposure of subsoil material at the base of the ruts where macrostructure rapidly deteriorated under wet conditions. We attribute the resultant moderately high hydraulic conductivities to the formation of stable microaggregates with fine sand to coarse silt textures. We conclude that the topsoil macrostructure of Ferralsols is subject to similar deterioration to that of Luvisols in temperate zones. The stable microstructure prevents marked compaction and decrease in hydraulic conductivity under wetter and more plastic soil conditions. However, typical tropical storms may regularly exceed the infiltration capacity of the deformed soils. In the deeper ruts water may concentrate and cause surface run-off, even in gently sloping areas. To avoid soil erosion, logging operations in sloping areas should therefore be restricted to dry soil conditions when rut formation is minimal.

Cutaneous hypersensitivity induced in rabbits by extracts of the tick Amblyomma cajennense (Acari : Ixodidae)

The cutaneous hypersensitivity test was used to correlate host resistance to ticks and type of reactions elicited by Amblyomma cajennense (Fabricius, 1787) tick extract in rabbits. Rabbits were divided into 3 groups of 2 animals each: naive, pre-infested and control. Cutaneous hypersensitivity was induced by intradermal inoculation of 25 mug extract in 0.03 rut of phosphate buffered saline (PBS) in rabbit ears. Control rabbits were inoculated with PBS only. The ear thickness was measured with a Mitutoyo(R) device before and 10 min, 1, 2,4,18, 24,48,72 and 96 h post-inoculation (PI). Pre-infested rabbits showed an immediate type reaction within the 1st 10 min PI (60 % increase in ear thickness) and a delayed reaction (18 h) (85 % increase), whereas the naive rabbits showed only the immediate reaction within the 1st 4 h (60 % increase). PBS induced only mild reactions. These results point out the crucial role of the cellular immune response of rabbits in the expression of resistance to A. cajennense.

Scraping Behavior in Male White-tailed Deer as a Potential Means of Transmitting Chronic Wasting Disease

Chronic wasting disease (CWD) has become a concern for wildlife managers and hunters across the United States. High prevalence of chronic wasting disease (CWD) in older male white-tailed deer (Odocoileus virginianus) suggests that sex-specific social behavior may contribute to the spread of the disease among males. Scraping is a marking behavior performed by male white-tailed deer during the rut in which a pawed depression and associated over-hanging branch are marked with saliva, glandular secretions, urine, and feces. We placed 71 and 35 motion-activated cameras on scrapes in DeSoto National Wildlife Refuge in western Nebraska and eastern Iowa from Oct. – Nov. 2005 and Sept. – Nov. 2006, respectively. We recorded 5009 encounters and 1830 direct interactions. We developed an ethogram of behaviors of interest at scrapes. We found that males interacted with scrapes more frequently than females (P < 0.001). Male interactions were more complex, with 69% consisting of ≥2 observed behaviors versus 25% and 13% for females and fawns. We identified individual male deer ≥2.5 years old and determined the minimum number of different scrapes individuals visited and the number of individuals that visit a single scrape. Individuals that appeared on camera ≥5 times visited a mean of 3.9 scrapes (range = 1-15) and traveled a mean minimum distance of 978 m between consecutive scrapes. A mean of 5.1 individuals visited a single scrape, and up to 43% of individuals returned to a scrape previously visited at least once. We modeled Risk Values based on frequency of occurrence, duration, and Threat Values of each behavior, for contacting and transmitting CWD prions at scrapes. Adult males had the highest total Risk Values for contacting CWD prions (114.1) and shedding prions (59.4). The “grasp-lick branch” behavior had the highest Risk Value for adult males for both contacting and transmitting prions. Our study reveals a sex specific social behavior in male white-tailed deer that has the potential to spread chronic wasting disease between adult males in the population.

Metodi biochimici e biomolecolari applicati alla medicina clinica: rendimento della real-time TaqMan PCR per la valutazione della resistenza alla claritromicina in H.pylori e tests fecali nella diagnorstica del carcinoma colo-rettale: M2PK, calprotectina e FOBT

1) Background: The most common methods to evaluate clarithromycin resistance is the E-Test, but is time consuming. Resistance of Hp to clarithromycin is due to point mutations in the 23S rRNA. Eight different point mutations have been related to CH resistance, but the large majority of the clarithromycin resistance depends on three point mutations (A2142C, A2142G and A2143G). A novel PCR-based clarithromycin resistance assays, even on paraffin-embedded biopsy specimens, have been proposed. Aims: to assess clarithromycin resistance detecting these point mutation (E-Test as a reference method);secondly, to investigate relation with MIC values. Methods: Paraffin-embedded biopsies of patients Hp-positive were retrieved. The A2142C, A2142G and A2143G point mutations were detected by molecular analysis after DNA extraction by using a TaqMan real-time PCR. Results: The study enrolled 86 patients: 46 resistant and 40 sensible to CH. The Hp status was evaluated at endoscopy, by rapid urease test (RUT), histology and hp culture. According to real-time PCR, 37 specimens were susceptible to clarithromycin (wild type dna) whilst the remaining 49 specimens (57%) were resistant. A2143G is the most frequent mutation. A2142C always express a resistant phenotype and A2142G leads to a resitant phenotype only if homozigous. 2) Background: Colonoscopy work-load for endoscopy services is increasing due to colorectal cancer prevention. We tested a combination of faecal tests to improve accuracy and prioritize the access to colonoscopy. Methods: we tested a combination of fecal tests (FOBT, M2-PK and calprotectin) in a group of 280 patients requiring colonoscopy. Results: 47 patients had CRC and 85 had advanced adenoma/s at colonoscopy/histology. In case of single test, for CRC detection FOBT was the test with the highest specificity and PPV, M2-PK had the highest sensitivity and higher NPV. Combination was more interesting in term of PPV. And the best combination of tests was i-FOBT + M2-PK.

Laboratory study of grouted macadams impregnated with mine waste geopolymeric binder

A new type of pavement has been gaining popularity over the last few years in Europe. It comprises a surface course with a semi-flexible material that provides significant advantages in comparison to both concrete and conventional asphalt, having both rut resistance and a degree of flexibility. It also provides good protection against the ingress of water to the foundation, since it has an impermeable surface. The semi-flexible material, generally known as grouted macadam, comprises an open-graded asphalt skeleton with 25% to 35% voids into which a cementitious slurry is grouted. This hybrid mixture provides good rut resistance and a surface highly resistant to fuel and oil spillage. Such properties allow it to be used in industrial areas, airports and harbours, where those situations are frequently associated with heavy and slow traffic. Grouted Macadams constitute a poorly understood branch of pavement technology and have generally been relegated to a role in certain specialist pavements whose performance is predicted on purely empirical evidence. Therefore, the main objectives of this project were related to better understanding the properties of this type of material, in order to predict its performance more realistically and to design pavements incorporating grouted macadam more accurately. Based on a standard mix design, several variables were studied during this project in order to characterise the behaviour of Grouted Macadams in general, and the influence of those variables on the fundamental properties of the final mixture. In this research project, one approach was used to the design of pavements incorporating Grouted Macadams: a traditional design method, based on laboratory determined of the stiffness modulus and the compressive strength.

Il dimensionamento delle sovrastrutture stradali non pavimentate

A comparison between main design methods for unpaved roads is presented in this paper. An unpaved road is made up of an unbound aggregate base course lying on a usually weak subgrade. A geosynthetic might be put between the two in reinforcing and separating function. The goal of a design method is to find the appropriate thickness of the base course knowing at least traffic volume, wheel load, tire pressure, undrained cohesion of the subgrade, allowable rut depth and influence of the reinforcement. Geosynthetics can reduce the thickness or the quality of aggregate required and improve the durability of an unpaved road. Geotextiles contribute to save aggregate through interaction friction and separation, while geogrids through interlocking between his apertures and lithic base elements. In the last chapter a case study is discussed and design thicknesses with two design methods for the three possible cases (i.e. unreinforced, geotextile reinforced, geogrid reinforced) are calculated.

The enduring effects of psychodynamic treatments vis-à-vis alternative treatments: A multilevel longitudinal meta-analysis

Although evidence suggests that the benefits of psychodynamic treatments are sustained over time, presently it is unclear whether these sustained benefits are superior to non-psychodynamic treatments. Additionally, the extant literature comparing the sustained benefits of psychodynamic treatments compared to alternative treatments is limited with methodological shortcomings. The purpose of the current study was to conduct a rigorous test of the growth of the benefits of psychodynamic treatments relative to alternative treatments across distinct domains of change (i.e., all outcome measures, targeted outcome measures, non-targeted outcome measures, and personality outcome measures). To do so, the study employed strict inclusion criteria to identify randomized clinical trials that directly compared at least one bona fide psychodynamic treatment and one bona fide non-psychodynamic treatment. Hierarchical linear modeling (Raudenbush, Bryk, Cheong, Congdon, & du Toit, 2011) was used to longitudinally model the impact of psychodynamic treatments compared to non-psychodynamic treatments at post-treatment and to compare the growth (i.e., slope) of effects beyond treatment completion. Findings from the present meta-analysis indicated that psychodynamic treatments and non-psychodynamic treatments were equally efficacious at post-treatment and at follow-up for combined outcomes (k=20), targeted outcomes (k=19), non-targeted outcomes (k=17), and personality outcomes (k=6). Clinical implications, directions for future research, and limitations are discussed.
