Les cartes de serveis de les biblioteques de recerca, biblioteques públiques i arxius catalans: un estat de la qüestió

Anàlisi sobre l'estat de la qüestió a Catalunya de les cartes de serveis, accessibles mitjançant la web, del centres d'informació de titularitat pública (biblioteques de recerca ¿universitàries, parlamentàries i nacionals-, biblioteques públiques i arxius històrics i administratius). L'estudi s'ha fet tenint en compte els requeriments sobre la qualitat elaborats per l'Administració General de l'Estat. Les dades recollides mostren una realitat diversa per a cada tipologia de centres malgrat l'existència d'una legislació estatal que avala la promoció, creació i manteniment de les cartes de serveis. El grau d'implantació depèn de la visió que tenen les organitzacions o dels requeriments del seu entorn. Les biblioteques de recerca compten majoritàriament amb cartes de serveis mentre que els arxius històrics i municipals no disposen de cap carta de serveis en línia a més de tenir escassa visibilitat a la xarxa; per contra, les biblioteques públiques municipals evidencien el fet que l¿existència o no d'una carta de serveis està directament relacionada amb el compromís dels professionals que estan al càrrec de la biblioteca.

Anàlisi multivariada craniomètrica de les poblacions catalano-balears del passat

S'ha portat a terme una analisi estadística de les dades craniometriques de les principals poblacions catalano-balears del passat, des de J'Edat del Bronze fins a l'Edat Mitjana, i posteriorment s'han integrat les poblacions en un context peninsular més ampli. S'han analitzalles relacions entre poblacions per mitja d'un analisi d'agrupament (cluster), emprant els algoritmes UPGMA i del "veí més proper" i la distancia euclídea al quadrat. Així mateix, s'ha realitzat un re-mostreig (bootstrap) per comprovar la robustes de les agrupacions obtingudes i un test de Mantel per comprovar el grau de concordan~a entre les poblacions femenines i masculines. Els resultats mostren que, a nivell peninsular, els Bascos són la població més diferenciada de la resta des d'un punt de vista morfologic, la qual cosa pot estar relacionada amb una major antiguitat d'aquesta població, potser present des de temps pre-neolítics. La segona font de variació peninsular la constitueixen dues poblacions amb possibles influencies foranies d'origen africa: jueus i musulmans. La resta de poblacions, incloent-hi les de Mallorca, són notablement homogenies a pesar de la seva heterogene'itat cultural, temporal i geogràtfica. Finalment, es conclou que no hi ha cap analisi estadística que objectivament recolzi I'existencia deIs tipus racials tradicionalmcnt descrits a la Península Iberica, i que responen a una visió tipologica i estatica de la diversitat humana.

Towards a theory of the credit-risk balance sheet

This article designs what it calls a Credit-Risk Balance Sheet (the risk being that of default by customers), a tool which, in principle, can contribute to revealing, controlling and managing the bad debt risk arising from a company¿s commercial credit, whose amount can represent a significant proportion of both its current and total assets.To construct it, we start from the duality observed in any credit transaction of this nature, whose basic identity can be summed up as Credit = Risk. ¿Credit¿ is granted by a company to its customer, and can be ranked by quality (we suggest the credit scoring system) and ¿risk¿ can either be assumed (interiorised) by the company itself or transferred to third parties (exteriorised).What provides the approach that leads to us being able to talk with confidence of a real Credit-Risk Balance Sheet with its methodological robustness is that the dual vision of the credit transaction is not, as we demonstrate, merely a classificatory duality (a double risk-credit classification of reality) but rather a true causal relationship, that is, a risk-credit causal duality.Once said Credit-Risk Balance Sheet (which bears a certain structural similarity with the classic net asset balance sheet) has been built, and its methodological coherence demonstrated, its properties ¿static and dynamic¿ are studied.Analysis of the temporal evolution of the Credit-Risk Balance Sheet and of its applications will be the object of subsequent works.

AMADEUS: advanced manipulation for deep underwater sampling

AMADEUS is a dexterous subsea robot hand incorporating force and slip contact sensing, using fluid filled tentacles for fingers. Hydraulic pressure variations in each of three flexible tubes (bellows) in each finger create a bending moment, and consequent motion or increase in contact force during grasping. Such fingers have inherent passive compliance, no moving parts, and are naturally depth pressure-compensated, making them ideal for reliable use in the deep ocean. In addition to the mechanical design, development of the hand has also considered closed loop finger position and force control, coordinated finger motion for grasping, force and slip sensor development/signal processing, and reactive world modeling/planning for supervisory `blind grasping¿. Initially, the application focus is for marine science tasks, but broader roles in offshore oil and gas, salvage, and military use are foreseen. Phase I of the project is complete, with the construction of a first prototype. Phase I1 is now underway, to deploy the hand from an underwater robot arm, and carry out wet trials with users.

Socio-economic inequalities in reported depression in Spain : a decomposition approach

Recent evidence questions some conventional view on the existence of income-related inequalities in depression suggesting in turn that other determinants might be in place, such as activity status and educational attainment. Evidence of socio-economic inequalities is especially relevant in countries such as Spain that have a limited coverage of mental health care and are regionally heterogeneous. This paper aims at measuring and explaining the degree of socio-economic inequality in reported depression in Spain. We employ linear probability models to estimate the concentration index and its decomposition drawing from 2003 edition of the Spanish National Health Survey, the most recent representative health survey in Spain. Our findings point towards the existence of avoidable inequalities in the prevalence of reported depression. However, besides ¿pure income effects¿ explaining 37% of inequality, economic activity status (28%), education (15%) and demographics (15%) play also a key encompassing role. Although high income implies higher resources to invest and cure (mental) illness, environmental factors influencing in peoples perceived social status act as indirect path as explaining the prevalence of depression. Finally, we find evidence of a gender effect, gender social-economic inequality in income is mainly avoidable.

Miguel de Unamuno i Heràclit: de ‘La elegía eterna’ a ‘La flor tronchada’

[cat] L’objectiu d’aquest breu article és provar i analitzar la influència de la saviesa d’Heràclit en alguns poemes de Miguel de Unamuno com ara ‘La elegía eterna’ i ‘La flor tronchada’. En certes ocasions –‘La elegía eterna’- Heràclit és per a ell una mena de crossa amb l’ajut de la qual reïx a mostrar poèticament les seves angoixes i, en d’altres –‘La flor tronchada’- necessita realment Heràclit per a il•lustrar la seva visió de Déu i de la vida humana com una lluita o guerra permanent.

A quantitative test of Hamilton's rule for the evolution of altruism.

The evolution of altruism is a fundamental and enduring puzzle in biology. In a seminal paper Hamilton showed that altruism can be selected for when rb - c > 0, where c is the fitness cost to the altruist, b is the fitness benefit to the beneficiary, and r is their genetic relatedness. While many studies have provided qualitative support for Hamilton's rule, quantitative tests have not yet been possible due to the difficulty of quantifying the costs and benefits of helping acts. Here we use a simulated system of foraging robots to experimentally manipulate the costs and benefits of helping and determine the conditions under which altruism evolves. By conducting experimental evolution over hundreds of generations of selection in populations with different c/b ratios, we show that Hamilton's rule always accurately predicts the minimum relatedness necessary for altruism to evolve. This high accuracy is remarkable given the presence of pleiotropic and epistatic effects as well as mutations with strong effects on behavior and fitness (effects not directly taken into account in Hamilton's original 1964 rule). In addition to providing the first quantitative test of Hamilton's rule in a system with a complex mapping between genotype and phenotype, these experiments demonstrate the wide applicability of kin selection theory.

Fabricants, comerciants i banquers. Les estructures comercials de la indústria cotonera catalana en el mercat español (1840-1936)

Aquesta tesi analitza la integració vertical entre fabricació, comercialització i finançament a la indústria catalana del període 1840-1936. L¿evidència obtinguda de les fonts arxivístiques confirma la visió tradicional quant a la descripció dels fets, però ofereix una interpretació alternativa, més optimista, de les causes i de les conseqüències. Els fabricants s¿implicaren en la comercialització perquè ells eren els coordinadors entre oferta i demanda (no com en el cas britànic, on ho eren els comerciants), i per tant havien de tenir un peu a cada banda. A més, els fabricants eren els més ben situats per a ser uns banquers eficients dels seus clients.

Automatic Prediction of Facial Trait Judgments: Appearance vs. Structural Models

Evaluating other individuals with respect to personality characteristics plays a crucial role in human relations and it is the focus of attention for research in diverse fields such as psychology and interactive computer systems. In psychology, face perception has been recognized as a key component of this evaluation system. Multiple studies suggest that observers use face information to infer personality characteristics. Interactive computer systems are trying to take advantage of these findings and apply them to increase the natural aspect of interaction and to improve the performance of interactive computer systems. Here, we experimentally test whether the automatic prediction of facial trait judgments (e.g. dominance) can be made by using the full appearance information of the face and whether a reduced representation of its structure is sufficient. We evaluate two separate approaches: a holistic representation model using the facial appearance information and a structural model constructed from the relations among facial salient points. State of the art machine learning methods are applied to a) derive a facial trait judgment model from training data and b) predict a facial trait value for any face. Furthermore, we address the issue of whether there are specific structural relations among facial points that predict perception of facial traits. Experimental results over a set of labeled data (9 different trait evaluations) and classification rules (4 rules) suggest that a) prediction of perception of facial traits is learnable by both holistic and structural approaches; b) the most reliable prediction of facial trait judgments is obtained by certain type of holistic descriptions of the face appearance; and c) for some traits such as attractiveness and extroversion, there are relationships between specific structural features and social perceptions.
