Evaluating the validity of the French version of the Four-Dimensional Symptom Questionnaire with differential item functioning analysis

Background. GPs are daily confronted with mental disorders and psychosomatic problems. The Four-Dimensional Symptom Questionnaire (4DSQ), measuring distress, depression, anxiety and somatization, was purposively developed for primary care. It has been translated into 12 languages and is commonly used in several countries. It was translated into French in 2008, by forward and backward translation, but it has not been validated for a primary care population. Aim. This study aimed to establish whether the French 4DSQ measured the same constructs in the same way as the original Dutch 4DSQ. Method. Two samples of French general practice patients were recruited during routine care to obtain as much variability as possible. One sample included consecutive patients, from the waiting room of rural GPs, over a period of 2 weeks and the other sample included patients with suspected psychological problems or unexplained symptoms. This population was compared to a matched Dutch sample using confirmatory factor analysis (CFA) and differential item functioning (DIF) analysis. Results. A total of 231 patients, from 15 French GPs, completed the questionnaire (Dutch reference group: 231). Mean age was 42.9 years (Dutch: 42.1); females numbered 71% in both samples. The multigroup CFA assessed configural invariance of one-factor models per 4DSQ scale. Thirteen of the total of 50 items in the 4DSQ, in three scales, were detected with DIF. However, DIF did not impact on the scale scores. Conclusion. French 4DSQ scales have the same latent structures and measure the same traits as the original Dutch 4DS

Flexible procedural terrain and biome generation

Denne bacheloroppgaven beskriver et svært fleksibelt prosessegenererings-rammeverk som kan bli integret i andre programmer, som spill, modellering og visualisering. Produktet er laget I Unity3D (en populær 3D spillmotor) og kan brukes i Unity3D og andre prosjekter som ikke bruker Unity3D. Vårt prosessegenererings-rammeverk kan bli brukt til å utvikle kart og terreng, enten det er for spill eller visualisering av 3D verdener. Programmet bryter prosessegenereringen ned i flere individuelle steg og inkluderer en samling av generatorer som håndterer forskjellige steg i prosessen (kalt steg-generatorer i oppgaven). Disse stegene inkluderer prosesser som å finne høydeverdiene til landskapet, skapelse av elver, og simulering av vind. Brukere kan velge og blande forskjellige steg-generatorer fra et stort utvalg av algoritmer. Disse stegene har alle parameter som lar brukeren tilpasse hvordan terrenget blir bygd. For eksempel hvor ujevn høydeverdiene bør være, hvor mange elver som bør lages, eller hvor sensitiv vinden bør være til høydeforskjeller. Brukerne kan også lettvint lage sine egne steg-generatorer med minimal ekstra kode, for å tilpasse sine spesifikke behov. Verktøykassen er designet for å være effektiv når et spill skal testes og utvikles, når kart skal designes og tilpasses, og når kart skal gjennomgå prosessegenereringen i kjøretid. Hovedmotivasjonen for prosjektet kom når Progress Interactive AS, et lite indie spillstudio, kontaktet oss og så etter et prosessegenererings-program de kunne bruke for å hjelpe dem med å lage kart til et sanntids-strategispill de jobber med. Vår løsning fullfører dette behovet. Produktet er også svært fleksibelt, og lett å bruke for hvem som helst andre som kan trenge prosessegenerering for terreng.This thesis describes a highly flexible procedural generation framework that can be integrated with other programs, such as games, modelling and visualization software. The product is made in Unity3D (a popular 3D game engine) and it can be used for Unity3D and other projects that do not use Unity3D. Our procedural generation framework can be used to develop maps and terrain, whether for games or visualizations of 3D worlds. The program breaks the process of generating terrain down into several individual steps and provides a collection of generators that handle different steps in the process (referred to here as step generators). These steps include processes like determining the altitudes of the landscape, spawning rivers, and simulating wind. Users can pick and mix different step generators from a wide selection of pre-made algorithms. These steps all have parameters that allow the user to customize how the terrain is constructed, such as how rough the altitudes should be, how many rivers should be included, or how sensitive the wind should be to altitude changes. The users can also easily make their own step generators with minimal extra code required, to make them fit their specific needs. The toolbox is designed to be effective when testing and developing a game, when designing and curating maps, and when procedurally generating at runtime. The main motivation for our project came when Progress Interactive AS, a small indie game studio, approached us wanting a procedural terrain generation program they could use to aid in making maps for a real-time strategy game they have been working on. Our solution fits their game requirements. In addition, the product is also made to be highly flexible and easy to use in any other use case that requires procedural terrain generation

Behaviour of Recent Aesthetics Assessment Models with Professional Photography

Aesthetic quality assessment for photographs is an important research topic since it can be used by a number of applications, such as image database management or image browsing. In 2012, the Aesthetic Visual Analysis (AVA) dataset has been proposed. Those 255,000 aesthetically annotated images are a key ingredient for training and for testing new models for aesthetics prediction. As AVA dataset is mainly composed of competitive photographs, we evaluate whether or not those computational models of aesthetics generalize well and perform well over professional photographs. We notice that the different models we test behave quite differently. Besides, we fine-tune the model using professional photographs and the results show that this process is effective

Sleeping arrangements and mass distribution of bed nets in six districts in central and northern Mozambique

OBJECTIVE: Universal coverage with insecticide-treated bed nets is a cornerstone of modern malaria control. Mozambique has developed a novel bed net allocation strategy, where the number of bed nets allocated per household is calculated on the basis of household composition and assumptions about who sleeps with whom. We set out to evaluate the performance of the novel allocation strategy. METHODS: 1,994 households were visited during household surveys following two universal coverage bed net distribution campaigns in Sofala and Nampula Provinces in 2010-2013. Each sleeping space was observed for the presence of a bed net, and the sleeping patterns for each household were recorded. The observed coverage and efficiency were compared to a simulated coverage and efficiency had conventional allocation strategies been used. A composite indicator, the product of coverage and efficiency, was calculated. Observed sleeping patterns were compared with the sleeping pattern assumptions. RESULTS: In households reached by the campaign, 93% (95% CI: 93-94%) of sleeping spaces in Sofala and 84% (82-86%) in Nampula were covered by campaign bed nets. The achieved efficiency was high, with 92% (91-93%) of distributed bed nets in Sofala and 93% (91-95%) in Nampula covering a sleeping space. Using the composite indicator, the novel allocation strategy outperformed all conventional strategies in Sofala and was tied for best in Nampula. The sleeping pattern assumptions were completely satisfied in 66% of households in Sofala and 56% of households in Nampula. The most common violation of the sleeping pattern assumptions was that male children 3-10 years of age tended not to share sleeping spaces with female children 3-10 or 10-16 years of age. CONCLUSIONS: The sleeping pattern assumptions underlying the novel bed net allocation strategy are generally valid, and net allocation using these assumptions can achieve high coverage and compare favorably with conventional allocation strategies.

Evaluación de los métodos químico y biogénico para el tratamiento de drenaje ácido de mina a escala de laboratorio. Caso : Mina Cerro de Pasco

El problema ambiental que genera el drenaje ácido de minas (DAM) en general en nuestro país cuando se vierten estos sin ningún tratamiento en los cauces de ríos así como los drenajes ácidos de minas abandonadas (pasivos ambientales) que por años no tuvieron mayor importancia son los que motivaron la presente investigación para la resolución de un problema ambiental y social. Las Bacterias Sulfato Reductoras (BSR) son responsables de la producción de sulfuro de hidrógeno (H2S) en anaerobiosis a partir de sulfatos y un donador de electrones. El sulfuro producido se puede utilizar para precipitar metales catiónicos divalentes, permitiendo la biorremediación de efluentes contaminados. En la presente tesis se pretende demostrar la eficiencia técnico ambiental del empleo de bacterias sulfato-reductoras aisladas de lugares aledaños a los puntos de descarga en los Pantanos de Villa para el tratamiento del drenaje ácido de mina de la Unidad de producción Cerro de Pasco perteneciente a la compañía minera Volcan. Se empleó como fuente principal de sulfato el drenaje ácido de mina, y como donador de electrones y fuente de carbono y de energía para el crecimiento de las BSR los estiércoles de aves de corral, oveja y vaca. Las pruebas experimentales se llevaron a cabo tanto para el tratamiento químico como para el tratamiento biogénico para las primeras en reactores batch y reactores continuos y para el tratamiento biogénico en bioreactores anaerobios tanto en sistemas batch como en sistemas en dos etapas para la generación de BSR y luego en el contactor se producía la reacción de precipitación de los metales pesados.The environmental problem that generates the Mine Acid Drainage (MAD) in general in our country when these are spilled without any treatment in the riverbeds as well as the acid drainages of abandoned mines (environmental passives) that for years did not have bigger importance are the ones that motivated the present research for the resolution of an environmental and social problem. The Sulfate Reducing Bacteria (SRB) is responsible for the production of hydrogen sulfide (H2S) in anaerobiosis starting from sulfates and a donor of electrons. The sulfide produced can be used to precipitate cationic bivalents metals, allowing the bioremediation of polluted effluents. The present thesis is sought to demonstrate the environmental technical efficiency of the use of sulfate reducing bacteria isolated from places bordering the discharge points in The Villa Wetlands for the treatment of the acid drainage of the Production Unit of Cerro de Pasco belonging to the mining company Volcan. It was used as the main source of the sulfate mine drainage and as donor of electrons and source of carbon and of energy for the growth of the SRB, the manures of corral birds, sheep and cattle. The experimental trials were carried out as much for the chemical treatment as for the biogenic treatment for the first ones in batch reactors and continuous reactors and for the biogenic treatment in bioreactors anaerobes as much in systems batch as in systems in two stages for the generation of SRB and then in the contactor the reaction of precipitation of the heavy metals took place.Tesi

Entre gritos reprimidos e pés sobre a mata: violência, mobilidades e formas de silenciamentos na guerra de Cabo Delgado, Moçambique

This article explores narratives about how the war started in October 2017, in the extreme north of the province of Cabo Delgado, in Mozambique, by an armed group locally recognized as mashababos, prevails not only physical violence against populations in the conflicted regions, but also the other forms [of violence], from symbolic to psychological, through repression and silencing of the manifest will of the victims to talk about their traumas. Supported by an ethnography carried out between 2018 and 2021 in Nacaca, in a center built to house displaced people, the central thesis of this article is that the forced displacements imposed against the victims of the conflict under analysis, intersect not only with their exercise of memory in wanting to tell their lived experiences about the war, but also to the traumas that are created by the forms of silencing imposed by different actors that permeate their new spaces of refuge.Este artículo explora narrativas sobre cómo la guerra iniciada en octubre de 2017, en el extremo norte de la provincia de Cabo Delgado, en Mozambique, por un grupo armado localmente reconocido como mashababos, prevalece no solo la violencia física contra las poblaciones en las regiones en conflicto, pero también las demás formas [de violencia], desde la simbólica a la psicológica, pasando por la represión y silenciamiento de la voluntad manifiesta de las víctimas de hablar de sus traumas. Apoyada en una etnografía realizada entre 2018 y 2021 en Nacaca, en un centro construido para albergar a desplazados, la tesis central de este artículo es que los desplazamientos forzados impuestos a las víctimas del conflicto en análisis, se entrecruzan no solo con su ejercicio de memoria en querer contar sus experiencias vividas sobre la guerra, pero también a los traumas que generan las formas de silenciamiento impuestas por diferentes actores que permean sus nuevos espacios de refugio.Este artigo explora narrativas sobre como a guerra iniciada em Outubro de 2017, no extremo Norte da província de Cabo Delgado, em Moçambique, por um grupo armado localmente reconhecido por mashababos, impera não só a violência física contra populações das regiões conflagradas, mas também as outras formas [de violência], desde simbólicas a psicológicas, através de repressões e silenciamentos da manifesta vontade das vítimas de falar sobre os seus traumas. Amparado por uma etnografia realizada entre 2018 e 2021 em Nacaca, num centro construído para abrigar os deslocados de guerra, a tese central deste artigo é de que os deslocamentos forçados impostos contra as vítimas do conflito em análise, se interseccionam não só ao seu exercício de memória no querer contar as suas experiências vivenciadas sobre a guerra, mas também aos traumas que se criam pelas formas de silenciamentos impostos por diversos actores que perpassam aos seus novos espaços de refúgio

Efecto antibacteriano in vitro del látex “sangre de grado” (croton lechleri) frente a salmonella sp, aislada del tracto intestinal del cuy (cavia porcellus)

La presente investigación, tuvo como objetivo determinar el efecto antibacteriano in vitro del látex de Croton lechleri “sangre de grado” frente a Salmonella sp. aislada del tracto intestinal del cuy (Cavia porcellus). La muestra vegetal fue de 100 ml de látex de Croton lechleri, recolectada en la provincia de Bagua, Departamento de Amazonas. Para la determinación del efecto antibacteriano in vitro se utilizó el método de Kirby - Bouer, con 4 grupos de análisis: concentraciones del látex de Croton lechleri: T1 (50%), T2 (75%), T3 (100%) y control (T4) con norfloxacina 10 mcg, con 15 repeticiones en placas de agar Müeller-Hinton, incubadas a 37ºC por 24 horas. Los resultados fueron determinados en función a la medida del diámetro de los halos de inhibición, siendo el promedio de 6,33; 7,27 y 6,60mm para las concentraciones de látex de “sangre de grado” T1 (50%), T2 (75%), T3 (100%) respectivamente; el grupo con norfloxacina (T4) tuvo un diámetro promedio de 29,87mm. Se concluyó que la “sangre de grado” no tiene efecto antibacteriano sobre Salmonella sp. a diferencia de la norfloxacina, a la cual salmonella es sensible
