Exploration of implicit theories in the formation of expert opinion in portuguese criminal law

This dissertation examines different aspects involved in the formation of psychologists’ expert opinion in the Portuguese criminal justice system, more precisely, as this opinion is reflected in assessment reports. The present dissertation is comprised of three qualitative studies, the first sought to provide a general portrait of a sample of 106 forensic psychological reports as to their overall quality as measured in terms of relevance and coherence. Results show that the formal markers of quality are present in the sample analysed, a certain number of weaknesses have been observed, notably concerning the internal coherence of the reports as well as the relevance of the information reported on. The second study explored the opinions of 17 Portuguese judges and state prosecutors concerning the use they make of this type of forensic report. It appears that they consider these reports to be useful and very credible, specially so when they have been produced under the auspices of the National Institute of Legal Medicine and Forensic Sciences, which is the state forensic institution. Furthermore, it appears that judges and prosecutors were particularly interested in data that allowed for a personalised portrait of the assessee. The third study sought to better comprehend the conceptual bases on which psychologists construct their reports. To this end, an exploratory study was undertaken with a sample of key-actors; the analysis of their interviews shows that they define their judicial mandate as well as the basic concepts that are associated to this mandate in different ways. A theoretical framework provided by an implicit theories model was used to help understand these results.

Foraminiferal and Pteropod Records in the Late Quaternary Sequence off Northern Kerala and Their Oceanographic and Climatic Significance

In the present investigation, an attempt is made to study late Quaternary foraminiferal and pteropod records of the shelf of northern Kerala and to evaluate their potentiality in paleocenographic and paleoclimatic reconstruction. The study gives details of sediment cores, general characteristics of foraminifera and pteropod species recorded from the examined samples and their systematic classification, spatial distribution of Recent foraminifera and pteropods and their response to varying bathymetry, nature of substrate, organic matter content in sediment and hydrography across the shelf. An attempt is also made to establish an integrated chronostratigraphy for the examined core sections. An effort is also made to identify microfaunal criteria useful in biostratigraphic division in shallow marine core sections. An attempt is made to infer various factors responsible for the change in microfaunal assemblage. Reconstruction of sea level changes during the last 36,000 years was attempted based on the pteropod record. The study reveals a bathymetric control on benthic/planktic (BF/PF) foraminiferal and pteropods/planktic foraminiferal (Pt/PF) abundance ratio. Bathymetric distribution pattern of BF/PF ratio is opposite to the (Pt/PF) ratio with decreasing trend of former from the shore across the shelf. Quantitative benthic foraminiferal record in the surficial sediments reveals a positive correlation between the diversity and bathymetry. R-mode cluster analysis performed on 30n significant Recent benthic foraminiferal, determines three major assemblage.

Impact of teak and eucalypt monoculture on soils in the highlands of Kerala

Impact of teak and eucalypt monoculture on soils in the highlands of kerala .The thesis is arranged under nine chapters. The first chapter introduces the topic, reviews the literature pertaining to the study and presents the aims and objectives of the study. The second chapter briefly describes the study location. experimental design and sampling methodology. The third chapter deals with physical properties of plantation soils. The fourth and fifth chapters cover the chemical properties and macro- and micro nutrient status in plantation soils. The organic matter fractions in plantation soils are described in sixth chapter. First part of the seventh chapter presents the results of factor analysis and the second part deals with fertility index of plantations. All these chapters are self-contained with separate introduction, materials and methods and results and discussions. A general discussion of the results is included in the eighth chapter. The ninth chapter includes conclusions and summary A study that traces the variation in physical and chemical properties and nutrient status of teak soils with age of plantations, till the end of a rotation period is thus highly pertinent. Such a study, with an adjacent natural forest as a reference stand will not only generate information that will help us to understand the pattern of variation in soil properties, but will also aid us in formulating better management strategies. The data generated by such a study will be more useful if accompanied by information on soil changes following a short rotation plantation crop. As Eucalypt, a short rotation crop is the second major plantation crop in Kerala, it was chosen for the study.

Forms of Nitrogen (NO 3 - -N; NO 2 - -N and NH 2 CONH 2 -N) and their relations to A.O.U. in the Indian coastal waters of Arabian Sea

The distribution of three important dissolved forms of nitrogen, viz. nitrate, nitrite and urea in the surface and bottom water samples collected from 27 selected hydrographic profiles, in the Arabian Sea, along the west coast of India is described. Of the three forms, nitrate concentrations were the highest and comparatively higher concentrations were observed in the bottom water. Decomposition of organic matter resulting in the release of the thermodynamically stable nitrogen species, i.e. nitrate, may be the major factor resulting in higher nitrate concentrations at these depths, where the water is also characterized by low values of dissolved oxygen and temperature. The significant positive correlation between A.O.U. and nitrate of the bottom water samples emphasizes the role of oxidative decomposition of organic matter which plays an active role in reducing the oxygen concentrations below the theoretical values since at this depth ( 200 m) the net production is taken to be zero. This is also evidenced by the negative correlation of nitrate with dissolved oxygen and temperature, for the bottom samples

Arbeitszeitflexibilisierung in der westdeutschen Metall- und Elektroindustrie und die Verbandsstrategien - Eine vergleichende Analyse der arbeitszeitpolitischen Strategien des Arbeitgeberverbandes Gesamtmetall und der Industriegewerkschaft Metall

Arbeitszeitpolitik und Arbeitszeitgestaltung haben seit dem Tarifkompromiss im Jahre 1984 in der Metall-, und Elektroindustrie in der politischen und wissenschaftlichen Diskussion einen immensen Bedeutungszuwachs erfahren. Die Forderungen nach einer flexibleren Arbeitszeitgestaltung haben zeitgleich sowohl aus der Globalisierungsdiskussion und der Debatte um die Wettbewerbsfähigkeit des "Wirtschaftsstandorts Deutschland" heraus wie auch aus beschäftigungspolitischen Gründen neuen Auftrieb bekommen. Die Diskussion um die Arbeitszeit ist gleichzeitig von verschiedenen, meist gegensätzlichen Interessen geprägt: Auf der Beschäftigtenseite zielt die Arbeitszeitflexibilisierung nach wie vor auf Zeitsouveränität: d.h. auf eine bessere Vereinbarkeit der Arbeitszeit mit allen Aktivitäten außerhalb der Arbeitszeit ab. Demgegenüber stellt die Arbeitgeberseite den betriebswirtschaftlichen Aspekt in den Vordergrund. D.h. die Anpassung der Arbeitszeit an den tatsächlichen Arbeitsanfall. So soll durch aufeinander abgestimmte Gestaltung von Betriebszeit und Arbeitszeit die Erhöhung der Produktivität und die Sicherung der Wettbewerbsfähigkeit erzielt werden. Durch diesen Trend verlor das sog. Normalarbeitsverhältnis an Allgemeingültigkeit und die Flexibilisierung der Arbeitszeiten nahm seit langem kontinuierlich zu. Folge ist, dass mittlerweile eine breite Palette von Arbeitszeitmodellen existiert, in denen die gesetzlich und vertraglich vereinbarte Wochenarbeitszeit in den Dimensionen Lage, Länge und Verteilung flexibilisiert wird. Auch die Tarifverhandlungen und Auseinandersetzung der Tarifparteien zur Arbeitszeitpolitik sind dadurch gekennzeichnet, dass die Arbeitszeitflexibilisierung und Verlagerung der Tarifpolitik auf betriebliche Ebene einen Bedeutungszuwachs bekam und die Meinungsführerschaft in Sachen Arbeitszeitgestaltung von der IG Metall zu Gesamtmetall wechselte. Ziel der vorliegenden Dissertation war es, anhand einer empirisch-historischen Untersuchung über Einstellungen sowie Strategien von Gesamtmetall und IG Metall die Gestaltungsspielräume flexibler Arbeitszeitmodelle zu bestimmen und gleichzeitig die Defizite herauszuarbeiten. Die Untersuchung gründete sich in erster Linie auf die Dokumentenanalyse von Stellungnahmen der Gesamtmetall und IG-Metall-Leitungsgremien sowie Primär- und Sekundäranalyse von Befragungen der Beschäftigten. Die leitende Frage der Untersuchung war, ob es den Arbeitgeberverbänden und den Gewerkschaften gelingen konnte, die Erfordernisse eines Betriebes und die Belange der Beschäftigten weitgehend in Übereinstimmung zu bringen? Und (wenn ja) unter welchen Voraussetzungen die neuen flexiblen Arbeitszeitsysteme mit den betrieblichen und außerbetrieblichen Interessen der Beschäftigten zu vereinbaren sind. Den Hintergrund für diese Zielerreichung bildete der gesellschaftliche Konflikt zwischen Arbeit und Kapital. Denn die Schwierigkeit bzw. Komplexität lag in der Frage, wie die unterschiedlichen Interessen, die sich in der industriekapitalistischen Gesellschaft durch den Gegensatz "Kapital" und "Arbeit" bestimmen lassen, zu vereinbaren waren bzw. sind.

Effects of activated charcoal and quebracho tannins on the turnover of goat manure in irrigated organic agriculture of the subtropics

Agriculture in semi-arid and arid regions is constantly gaining importance for the security of the nutrition of humankind because of the rapid population growth. At the same time, especially these regions are more and more endangered by soil degradation, limited resources and extreme climatic conditions. One way to retain soil fertility under these conditions in the long run is to increase the soil organic matter. Thus, a two-year field experiment was conducted to test the efficiency of activated charcoal and quebracho tannin extract as stabilizers of soil organic matter on a sandy soil low in nutrients in Northern Oman. Both activated charcoal and quebracho tannin extract were either fed to goats and after defecation applied to the soil or directly applied to the soil in combination with dried goat manure. Regardless of the application method, both additives reduced decomposition of soil-applied organic matter and thus stabilized and increased soil organic carbon. The nutrient release from goat manure was altered by the application of activated charcoal and quebracho tannin extract as well, however, nutrient release was not always slowed down. While activated charcoal fed to goats, was more effective in stabilising soil organic matter and in reducing nutrient release than mixing it, for quebracho tannin extract the opposite was the case. Moreover, the efficiency of the additives was influenced by the cultivated crop (sweet corn and radish), leading to unexplained interactions. The reduced nutrient release caused by the stabilization of the organic matter might be the reason for the reduced yields for sweet corn caused by the application of manure amended with activated charcoal and quebracho tannin extract. Radish, on the other hand, was only inhibited by the presence of quebracho tannin extract but not by activated charcoal. This might be caused by a possible allelopathic effect of tannins on crops. To understand the mechanisms behind the changes in manure, in the soil, in the mineralisation and the plant development and to resolve detrimental effects, further research as recommended in this dissertation is necessary. Particularly in developing countries poor in resources and capital, feeding charcoal or tannins to animals and using their faeces as manure may be promising to increase soil fertility, sequester carbon and reduce nutrient losses, when yield reductions can be resolved.

Exploiting non-Markovianity for quantum control

Quantum technology, exploiting entanglement and the wave nature of matter, relies on the ability to accurately control quantum systems. Quantum control is often compromised by the interaction of the system with its environment since this causes loss of amplitude and phase. However, when the dynamics of the open quantum system is non-Markovian, amplitude and phase flow not only from the system into the environment but also back. Interaction with the environment is then not necessarily detrimental. We show that the back-flow of amplitude and phase can be exploited to carry out quantum control tasks that could not be realized if the system was isolated. The control is facilitated by a few strongly coupled, sufficiently isolated environmental modes. Our paradigmatic example considers a weakly anharmonic ladder with resonant amplitude control only, restricting realizable operations to SO(N). The coupling to the environment, when harnessed with optimization techniques, allows for full SU(N) controllability.

Actuación de UNAMID (operación híbrida de la Unión Africana y las Naciones Unidas en Darfur) en la defensa de los Derechos Humanos de las mujeres en el conflicto en Darfur (2008 – 2012)

El interés de esta monografía es analizar los alcances y las limitaciones de la actuación de UNAMID en la defensa de los Derechos Humanos de las mujeres en el conflicto en Darfur (2008-2012). Lo anterior, para dar cuenta de que si bien UNAMID ha tenido avances significativos en el aumento de denuncias por violación sexual, en la educación y en la inclusión de la mujer en Darfur, la intervención tardía, la falta de personal cualificado y el lento despliegue ha limitado su actuación para erradicar la violencia sexual como arma de guerra. Sin embargo, la baja internalización de la norma por parte del Estado de Sudán ha sido el mayor limitante para la Misión de Paz. Este análisis se realiza mediante el concepto de Responsabilidad de proteger y el enfoque de Alexander Wendt y Nicholas Onuf.

Análisis del gen adra2a receptor alfa 2a adrenergico en pacientes con trastorno de hiperactividad y déficit de atención

El trastorno de hiperactividad y déficit de atención (THDA), es definido clínicamente como una alteración en el comportamiento, caracterizada por inatención, hiperactividad e impulsividad. Estos aspectos son clasificados en tres subtipos, que son: Inatento, hiperactivo impulsivo y mixto. Clínicamente se describe un espectro amplio que incluye desordenes académicos, trastornos de aprendizaje, déficit cognitivo, trastornos de conducta, personalidad antisocial, pobres relaciones interpersonales y aumento de la ansiedad, que pueden continuar hasta la adultez. A nivel global se ha estimado una prevalencia entre el 1% y el 22%, con amplias variaciones, dadas por la edad, procedencia y características sociales. En Colombia, se han realizado estudios en Bogotá y Antioquia, que han permitido establecer una prevalencia del 5% y 15%, respectivamente. La causa específica no ha sido totalmente esclarecida, sin embargo se ha calculado una heredabilidad cercana al 80% en algunas poblaciones, demostrando el papel fundamental de la genética en la etiología de la enfermedad. Los factores genéticos involucrados se relacionan con cambios neuroquímicos de los sistemas dopaminérgicos, serotoninérgicos y noradrenérgicos, particularmente en los sistemas frontales subcorticales, corteza cerebral prefrontal, en las regiones ventral, medial, dorsolateral y la porción anterior del cíngulo. Basados en los datos de estudios previos que sugieren una herencia poligénica multifactorial, se han realizado esfuerzos continuos en la búsqueda de genes candidatos, a través de diferentes estrategias. Particularmente los receptores Alfa 2 adrenérgicos, se encuentran en la corteza cerebral, cumpliendo funciones de asociación, memoria y es el sitio de acción de fármacos utilizados comúnmente en el tratamiento de este trastorno, siendo esta la principal evidencia de la asociación de este receptor con el desarrollo del THDA. Hasta la fecha se han descrito más de 80 polimorfismos en el gen (ADRA2A), algunos de los cuales se han asociado con la entidad. Sin embargo, los resultados son controversiales y varían según la metodología diagnóstica empleada y la población estudiada, antecedentes y comorbilidades. Este trabajo pretende establecer si las variaciones en la secuencia codificante del gen ADRA2A, podrían relacionarse con el fenotipo del Trastorno de Hiperactividad y el Déficit de Atención.

Metodología: estudio descriptivo, retrospectivo, tipo serie de casos. Se revisaron los registros de todos que recibieron radioterapia de salvamento que ofrece para a aquellos pacientes que ya tienen recaída bioquímica o local después de la Prostatectomia Radical, entre enero de 2003 y diciembre de 2007. Resultado: entre los 40 pacientes elegibles para el análisis, la media de seguimiento fue de 2,17 años, con una desviación estándar de 1,5 años, con un rango de 0 a 58 meses, la media de la edad fue de 66,12 años, con una desviación estándar de 6,63, con un rango entre 50 y 78 años. Todos los pacientes le realizaron prostatectomía. La media de supervivencia libre de enfermedad con intervalos de confianza del 95% fue de 4,58 años (2,24 a 4,92 años). Discusión: analizados los resultados en éste grupo de pacientes con cáncer de próstata sometidos a prostatectomía radical y radioterapia como terapia de salvamento, con un seguimiento promedio de 2,17 años, observamos que los resultados obtenidos en el presente estudio son inferiores a los registrados en otros reportes en la literatura (16-20).

Eficacia y seguridad de la melatonina para el manejo de los trastornos del sueño en el autismo: meta-análisis

INTRODUCCIÓN: El 80% de los niños y adolescentes con trastornos del espectro autista (TEA) presenta algún trastorno del sueño, en cuya génesis al parecer intervienen alteraciones en la regulación de la melatonina. El objetivo de este metaanálisis fue determinar la eficacia y seguridad de la melatonina para el manejo de ciertos trastornos del sueño en niños con TEA. MÉTODOS: Tres revisores extrajeron los datos relevantes de los ensayos clínicos aleatorizados doble ciego de alta calidad publicados en bases de datos primarias, de ensayos clínicos, de revisiones sistemáticas y de literatura gris; además se realizó búsqueda en bola de nieve. Se analizaron los datos con RevMan 5.3. Se realizó un análisis del inverso de la varianza por un modelo de efectos aleatorios para las diferencias de medias de los desenlaces propuestos: duración del tiempo total, latencia de sueño y número de despertares nocturnos. Se evaluó la heterogeneidad interestudios con el parámetro I2 RESULTADOS: La búsqueda inicial arrojó 355 resultados, de los cuales tres cumplieron los criterios de selección. La melatonina resultó ser un medicamento seguro y eficaz para aumentar la duración total del sueño y disminuir la latencia de sueño en niños y adolescentes con TEA; hasta el momento la evidencia sobre el número de despertares nocturnos no es estadísticamente significativa. DISCUSIÓN: A la luz de la evidencia disponible, la melatonina es una elección segura y eficaz para el manejo de ciertos problemas del sueño en niños y adolescentes con TEA. Es necesario realizar estudios con mayores tamaños muestrales y comparados con otros medicamentos disponibles en el mercado.

Cropping systems, carbon sequestration and erosion in Brazil, a review

Soils represent a large carbon pool, approximately 1500 Gt, which is equivalent to almost three times the quantity stored in terrestrial biomass and twice the amount stored in the atmosphere. Any modification of land use or land management can induce variations in soil carbon stocks, even in agricultural systems that are perceived to be in a steady state. Tillage practices often induce soil aerobic conditions that are favourable to microbial activity and may lead to a degradation of soil structure. As a result, mineralisation of soil organic matter increases in the long term. The adoption of no-tillage systems and the maintenance of a permanent vegetation cover using Direct seeding Mulch-based Cropping system or DMC, may increase carbon levels in the topsoil. In Brazil, no-tillage practices (mainly DMC), were introduced approximately 30 years ago in the south in the Parana state, primarily as a means of reducing erosion. Subsequently, research has begun to study the management of the crop waste products and their effects on soil fertility, either in terms of phosphorus management, as a means of controlling soil acidity, or determining how manures can be applied in a more localised manner. The spread of no-till in Brazil has involved a large amount of extension work. The area under no-tillage is still increasing in the centre and north of the country and currently occupies ca. 20 million hectares, covering a diversity of environmental conditions, cropping systems and management practices. Most studies of Brazilian soils give rates of carbon storage in the top 40 cm of the soil of 0.4 to 1.7 t C ha(-1) per year, with the highest rates in the Cerrado region. However, caution must be taken when analysing DMC systems in terms of carbon sequestration. Comparisons should include changes in trace gas fluxes and should not be limited to a consideration of carbon storage in the soil alone if the full implications for global warming are to be assessed.

The role of gypsum in the reactions of phosphate with soils

The aim of this study was to examine the mechanisms by which gypsum increases the sorption of fertilizer-P in soils of and and semi-arid regions. Either gypsum or soil (Usher from the UK; pH 7.8, 7% organic matter, 21% CaCO3: Yasouj from Iran; pH 8.2, 1.4% OM, 18% CaCO3: Ghanimeh from Saudi Arabia; pH 7.8, 1% OM, 26% CaCO3, 13% gypsum) was shaken for 24 It with KH2PO4 solutions in 10 mM CaCl2. With gypsum, grinding increased sorption by a factor of about 3, and increase in pH from 5.6 to 7.5 greatly increased sorption. Scanning electron micrographs (SEM) and EDX quantitative analysis showed that small crystals of gypsum disappeared and roughly spherical particles of dicalcium phosphate (DCPD) were formed. Analysis of equilibrium Solutions showed, using GEOCHEM, that octa-calcium phosphate (OCP) coated the DCPD. For the soils, sorption was in the order Ghanimeh > Yasouj > Usher. Removal of gypsum from Ghanimeh reduced sorption, with precipitated gypsum having a greater effect than gypsum mixed physically with the soil. Addition to Usher had no effect. SEM and EDX could not be used in the soil matrix, but solubility analysis again showed that solutions were close to equilibrium with OCP. Usher was unresponsive to added gypsum, presumably because of its small sorption capacity and high organic matter content. In Ghanimeh and Yasouj soils, gypsum increased sorption by being a source of readily available Ca2+ (c) 2005 Elsevier B.V. All rights reserved.
