La Participació dels estudiants en la universitat. Anàlisi de la situació a la Universitat de Girona

Aquest estudi posa a debat tant els nivells com les formes de participació dels estudiants en el funcionament de la universitat amb la finalitat d’aprofundir en els models i les dinàmiques que afavoreixen la participació dels estudiants. Parteix de l’estudi del cas de la Universitat de Girona i recull, des de diferents punts de vista, quina és la situació actual pel que fa a la participació dels estudiants en aquesta universitat, i es proposen algunes línies d’actuació per promoure-la. A la base d’aquest estudi se situa el convenciment que la participació dels estudiants en el funcionament de la universitat és un objectiu desitjable per part de la comunitat universitària, i que, com a centre de formació que és la universitat, cal que es plantegi la participació com un objectiu d’aprenentatge propi ja que, a més de formar científi cs i professionals en diferents àmbits, la universitat també contribueix (o hauria de contribuir) a la formació de ciutadans. Es tracta d’un treball fi nançat per la convocatòria 20 de la UdG d’ajuts a projectes cooperatius d’R+D en els àmbits humanístic i de les ciències socials i que s’ha desenvolupat en la seva major part durant l’any 2008 i inicis del 2009. Les dades de participació que es presenten sobre la UdG són de l’any 2008

Severidade punitiva : penas severas: um factor de dissuasão de um crime?

A justiça e a Psicologia Forense movimentam-se no mesmo terreno, o das personalidades e comportamentos humanos, no entanto, operam em campos não tão complementares quanto o necessário. O berço da investigação respeita a História e evolução da penalidade, sobrevoando posteriormente nos caminhos (en) cruzilhados entre a Psicologia e o Direito. Particularizou-se os laços que envolvem a avaliação psicológica forense e a perícia de personalidade quando pedidas em tribunal, e deslizou-se superficialmente pela ética e deontologia. A sua máxime consiste na procura de conhecimentos sobre o nível de Severidade Punitiva, em processos de menores relativos à aplicação da Lei Tutelar Educativa, sendo a adolescência uma etapa da vida onde frequentemente se cometem algumas condutas transgressivas e onde as mesmas emergem Para isso, aplicou-se um instrumento psicológico construído para o efeito, o Índice de Severidade Penalizadora e Psicologização (Criminalização Secundária – Transgressionalidades e Delinquência Juvenil (ISPP-CS-TDJ). Finalmente ousa responder à pergunta “Penas severas como factor de dissuasão de um crime?”

A influência da psicologia no discurso do sentenciador: severidade "punitiva"e psicologização na justiça de menores

RESUMO: A presente dissertação, integrada no Mestrado de Psicologia Forense e da Exclusão Social, da Universidade Lusófona de Humanidades e Tecnologias, tem dois objectivos fundamentais: a análise da severidade das medidas tutelar educativas, na Justiça de Menores em Portugal e, avaliar o contributo do saber da Psicologia, no momento da decisão e escolha dessas mesmas medidas, pelo aplicador da lei. Para isso, foram analisados 58 Processos Tutelares Educativos, presentes no Tribunal de Família e Menores de Lisboa, e 11 arquivados na Direcção Geral de Reinserção Social, incidindo a análise, sobretudo, no tipo de medidas aplicadas, o género de crimes cometidos, e a referência a avaliações psicológicas ou perícias sobre a personalidade, como fundamento da decisão. Estes processos são analisados à luz de um instrumento de medida da aplicação de medidas tutelares em jovens, com idades compreendidas entre os 12 e os 16 anos: o Índice de Severidade Penalizadora e Psicologização no âmbito da transgressionalidade e delinquência juvenil (Criminalização Secundária – IPSS-CS-TDJ), de 2011. Os resultados evidenciam índices médios de severidade punitiva e de psicologização. Este estudo, dado o seu carácter pioneiro, representa, uma tentativa de abordagem empírica do problema. Para futuras investigações propõe-se a aplicação do instrumento a processos judiciais de outras regiões do país. ABSTRACT: The present thesis, integrated into Forensic Psychology and Social Exclusion Masters Degree, of Lusophone University of Humanities and Technologies, has two fundamental objectives: an analysis of the tutelary educative measures severity, in juvenile justice system, in Portugal, and evaluate the contribution of the knowledge of psychology, at the moment of decision and choice of those measures, by judge. For this, were analyse 58 tutelary educative processes, belonging to the Family and Juvenile Court of Lisbon, and 11 archived in General Direction of Social Reintegration, focusing, mainly, on the type of measures applied, kind of crimes, and reference to psychological evaluations or personality investigation, as foundation of judicial decision. These processes are analysed based on an instrument to measure the application of punitive measure to young people: Punishment Severity Index and Psychologisation in the framework of Infringement and Juvenile Delinquency (ISPP-CSTDJ), 2011. The results show an average level of punishment severity and psychologisation. This study, represents a pioneer empirically approach to the problem. In order to future investigations is proposed apply the instrument to processes from other regions of the country.

Modelo tipo de dermatite atópica em rato

A dermatite atópica (DA) é um tema importante na dermatologia clínica. Na verdade, a patogénese dessa doença inflamatória crónica da pele, caracterizada principalmente por pele seca e prurido, ainda está longe de ser totalmente compreendida. A fim de saber mais acerca desta complexa doença, ratos Wistar machos e adultos (n = 10) foram utilizados como modelo animal, nos quais o tratamento com acetona (AA) foi comparado com o tratamento com água por 3 dias (AW). No dia 3, uma hora após o último tratamento, a AA mostrou maior perda transepidérmica de água (TEWL), fluxo sanguíneo capilar e reduzida hidratação quando comparada com AW. A análise comportamental mostrou que a acção de coçar foi marcadamente mais frequente no grupo AA (n = 5) quando comparado ao grupo AW (n = 5). Estes resultados justificam a implementação deste modelo animal como uma ferramenta experimental para investigação da AD.

Onset of recent rapid sea-level rise in the western Atlantic Ocean

A high-resolution record of sea-level change spanning the past 1000 years is derived from foraminiferal and chronological analyses of a 2m thick salt-marsh peat sequence at Chezzetcook, Nova Scotia, Canada. Former mean tide level positions are reconstructed with a precision of +/- 0.055 in using a transfer function derived from distributions of modern salt-marsh foraminifera. Our age model for the core section older than 300 years is based on 19 AMS C-14 ages and takes into account the individual probability distributions of calibrated radiocarbon ages. The past 300 years is dated by pollen and the isotopes Pb-206, Pb-207, Pb-210, Cs-137 and Am-241. Between AD 1000 and AD 1800, relative sea level rose at a mean rate of 17cm per century. Apparent pre-industrial rises of sea level dated at AD 1500-1550 and AD 1700-1800 cannot be clearly distinguished when radiocarbon age errors are taken into account. Furthermore, they may be an artefact of fluctuations in atmospheric C-14 production. In the 19th century sea level rose at a mean rate of 1.6mm/yr. Between AD 1900 and AD 1920, sea-level rise accelerated to the modern mean rate of 3.2mm/yr. This acceleration corresponds in time with global temperature rise and may therefore be associated with recent global warming. (c) 2005 Elsevier Ltd. All rights reserved.

The water quality of the River Carnon, west Cornwall, November 1992 to March 1994: the impacts of Wheal Jane discharges

In January 1992, there was a major pollutant event for the River Canon and downstream with its confluence to the River Fal and the Fal estuary in the west Cornwall. This incident was associated with the discharge of several million gallons of highly polluted water from the abandoned Wheal Jane tin mine that also extracted Ag, Cu and Zn ore. Later that year, the Centre for Ecology and Hydrology (CBH; then Institute of Hydrology) Wallingford undertook daily monitoring of the River Canon for a range of major, minor and trace elements to assess the nature and the dynamics of the pollutant discharges. These data cover an 18-month period when there remained major water-quality problems after the initial phase of surface water contamination. Here, a summary is provided of the water quality found, as a backdrop to set against subsequent remediation. Two types of water-quality determinant grouping were observed. The first type comprises the determinants B, Cs, Ca, Li, K, Na, SO4, Rb and Sr, and their concentrations are positively correlated with each other but inversely correlated with flow. This type of water-quality determinant shows variations in concentration that broadly link to the normal hydrogeochemical processes within the catchment, with limited confounding issues associated with mine drainage. The second type of water-quality determinant comprises Al, Be, Cd, Ce, Co, Cu, Fe, La, Pb, Pr, Nd, Ni, Si, Sb, U, Y and Zn, and concentrations for all this group are positively correlated. The determinants in this second group all have concentrations that are negatively correlated with pH. This group links primarily to pollutant mine discharge. The water-quality variations in the River Camon are described in relation to these two distinct hydrogeochemical groupings. (C) 2004 Elsevier B.V All rights reserved.

The development and contribution of surface charge by crop residues in two Malawian acid soils

The effects of maize and soya bean residues on the pH and charge of a loamy sand (Kawalazi) and a sandy clay loam (Naming'omba) from Malawi were measured to determine both the indirect effect of the residues on soil charge through the changes in pH, and the direct contribution of charge carried on the residue surfaces. The soils had pH values (10 mM CaCl2) of 4.3 and 5.0 and organic matter contents were 1.4% and 2.7%, respectively. The clay fractions were dominated by kaolinite and goethite, and mica was present in both samples. The soils were incubated for 28 days with maize (Zea mays) and soya bean (Glycine max) residues. The maximum addition of residue (12.0%) in the Kawalazi and Naming'omba soils increased the pH from 4.3 and 5.0 to 4.8 and 5.3 (maize) and to 9.0 and 8.8 (soya bean), respectively. Negative charge increased from 2.1 and 4.7 cmol(c) kg(-1) to 3.8 and 7.5 (maize) and to 5.3 and 9.3 cmol(c) kg(-1) (soya bean). Positive charge increased from 0.72 and 0.62 to 0.87 and 0.85 cmol(c) kg(-1) (maize) and to 0.75 and 0.68 (soya bean). The charge contribution by the residues was calculated by difference between the charge on a sample incubated with residue and the charge on a soil without residue limed to the same pH value. Up to 100 cmolc negative charge and 10 cmol(c) of positive charge per kg of residue were directly contributed to the soil-residue mixture, the amounts depending on the type of residue, the extent to which the residue was decomposed in the soil and the pH of the mixture. The Anderson and Sposito method [Soil Sci. Soc. Am. J. 55 (1991) 1569] was used to partition the permanent negative charge (holding Cs+) from variable negative charge (holding Li+). In the pH range 3.7-6.5 the maize residue contributed between 3 and 26 cmol(c) of variable charge per kg of residue in the Kawalazi soil and between 6 and 25 cmol(c) per kg of residue in the Naming'omba soil. For soya bean the values were between I and 28 and between 4 and 68 cmolc per kg of residue, respectively. At a given pH value, the charge tended to increase with time of incubation and for a given addition of residue, pH decreased during incubation. Addition of residues contributed no permanent negative charge and the charge on the soil measured by Cs adsorption was independent of pH change caused by the residue showing that the method is valid for soil-residue mixtures. With time there was a decrease in the amount of permanent charge probably due to masking as humic material become adsorbed on mineral surfaces. (C) 2003 Elsevier Science B.V. All rights reserved.

Scalability of efficient parallel K-Means

Clustering is defined as the grouping of similar items in a set, and is an important process within the field of data mining. As the amount of data for various applications continues to increase, in terms of its size and dimensionality, it is necessary to have efficient clustering methods. A popular clustering algorithm is K-Means, which adopts a greedy approach to produce a set of K-clusters with associated centres of mass, and uses a squared error distortion measure to determine convergence. Methods for improving the efficiency of K-Means have been largely explored in two main directions. The amount of computation can be significantly reduced by adopting a more efficient data structure, notably a multi-dimensional binary search tree (KD-Tree) to store either centroids or data points. A second direction is parallel processing, where data and computation loads are distributed over many processing nodes. However, little work has been done to provide a parallel formulation of the efficient sequential techniques based on KD-Trees. Such approaches are expected to have an irregular distribution of computation load and can suffer from load imbalance. This issue has so far limited the adoption of these efficient K-Means techniques in parallel computational environments. In this work, we provide a parallel formulation for the KD-Tree based K-Means algorithm and address its load balancing issues.

Analytical potentials for triatomic molecules VIII. A two valued surface for the lowest 1A¢ surfaces of H2O

Ab initio calculations of the energy have been made at approximately 150 points on the two lowest singlet A' potential energy surfaces of the water molecule, 1A' and 1A', covering structures having D∞h, C∞v, C2v and Cs symmetries. The object was to obtain an ab initio surface of uniform accuracy over the whole three-dimensional coordinate space. Molecular orbitals were constructed from a double zeta plus Rydberg basis, and correlation was introduced by single and double excitations from multiconfiguration states which gave the correct dissociation behaviour. A two-valued analytical potential function has been constructed to fit these ab initio energy calculations. The adiabatic energies are given in our analytical function as the eigenvalues of a 2 2 matrix, whose diagonal elements define two diabatic surfaces. The off-diagonal element goes to zero for those configurations corresponding to surface intersections, so that our adiabatic surface exhibits the correct Σ/II conical intersections for linear configurations, and singlet/triplet intersections of the O + H2 dissociation fragments. The agreement between our analytical surface and experiment has been improved by using empirical diatomic potential curves in place of those derived from ab initio calculations.

A review of growth for construction service companies in global markets

Throughout the developed world, professional services play an increasingly important part in an economy, with many countries showing a substantial positive trade balance for services. Yet, there has been relatively little research on construction services (CS) and, in particular, how well professional service companies (PSFs) perform in the international arena. The method for collecting services export information differs to the way in which goods and products exports data are gathered because of the intangible nature of services. Organisational growth of companies aims to share risks across different regions and sectors, however, the rapidly changing business environment challenges companies with the increasing foreign ownership and changes in procurement. The complexity of today’s international construction services organisations raises two questions: how the organisations can successfully manage growth and what are their motives for international trade. The research focuses on top UK consulting engineering companies to understand their organisational strategy, their export strategy, and drivers for overseas activities. The data will feed a model of professional services exports, which can help to inform the way services export data could be collected to better reflect the industry’s performance.

Unravelling the conundrum of tannins in animal nutrition and health

This paper examines the nutritional and veterinary effects of tannins on ruminants and makes some comparisons with non-ruminants. Tannin chemistry per se is not covered and readers are referred to several excellent reviews instead: (a) Okuda T et al. Heterocycles 30:1195-1218 (1990); (b) Ferreira D and Slade D. Nat Prod Rep 19:517-541 (2002); (c) Yoshida T et al. In Studies in Natural Product Chemistry. Elsevier Science, Amsterdam, pp. 395-453 (2000); (d) Khanbabaee K and van Ree T. Nat Prod Rep 18:641-649 (2001); (e) Okuda et al. Phytochemistvy 55:513-529 (2000). The effects of tannins on rumen micro-organisms are also not reviewed, as these have been addressed by others: (a) McSweeney CS et al. Anim Feed Sci Technol 91:83-93 (2001); (b) Smith AH and Mackie RI. Appl Environ Microbiol 70:1104-1115 (2004). This paper deals first with the nutritional effects of tannins in animal feeds, their qualitative and quantitative diversity, and the implications of tannin-protein complexation. It then summarises the known physiological and harmful effects and discusses the equivocal evidence of the bioavailability of tannins. Issues concerning tannin metabolism and systemic effects are also considered. Opportunities are presented on how to treat feeds with high tannin contents, and some lesser-known but successful feeding strategies are highlighted. Recent research has explored the use of tannins for preventing animal deaths from bloat, for reducing intestinal parasites and for lowering gaseous ammonia and methane emissions. Finally, several tannin assays and a hypothesis are discussed that merit further investigation in order to assess their suitability for predicting animal responses. The aim is to provoke discussion and spur readers into new approaches. An attempt is made to synthesise the emerging information for relating tannin structures with their activities. Although many plants with high levels of tannins produce negative effects and require treatments, others are very useful animal feeds. Our ability to predict whether tannin-containing feeds confer positive or negative effects will depend on interdisciplinary research between animal nutritionists and plant chemists. The elucidation of tannin structure-activity relationships presents exciting opportunities for future feeding strategies that will benefit ruminants and the environment within the contexts of extensive, semi-intensive and some intensive agricultural systems.
