El amor en Plutarco: la necesaria corrección platónica de Platón

Con ocasión del simposio internacional dedicado al amor en Plutarco, este trabajo fue presentado para mostrar hasta qué punto Plutarco, sobre todo en su Erótico y desde parámetros estrictamente platónicos, con la ayuda de una lógica elemental y a la vez rigurosa, se limita a corregir platónicamente a Platón a fin de que éros y philía puedan ser atribuidos también al amor conyugal.

L'amor a Plutarc: la necessària correcció platònica de Plató

Amb ocasió del simposi internacional dedicat a l'amor a Plutarc, aquest treball fou presentat per mostrar fins a quin punt Plutarc, sobre tot al seu Eròtic i des de paràmetres estrictament platònics, amb l'ajut d'una lògica elemental i alhora rigorosa, es limita a corregir platònicament Plató per tal que éros i philía puguin ser atribuïts també al amor conjugal.

A Mixed-method Social Networks Study Design for Research on Transnational Families

This paper advocates the adoption of a mixed-methods research design to describe and analyze ego-centered social networks in transnational family research. Drawing on the experience of the Social Networks Influences on Family Formation project (2004-2005), I show how the combined use of network generators and semistructured interviews (N = 116) produces unique data on family configurations and their impact on life course choices. A mixed-methods network approach presents specific advantages for research on children in transnational families. On the one hand, quantitative analyses are crucial for reconstructing and measuring the potential and actual relational support available to children in a context where kin interactions may be hindered by temporary and prolonged periods of separation. On the other hand, qualitative analyses can address strategies and practices employed by families to maintain relationships across international borders and geographic distance, as well as the implications of those strategies for children's well-being.

Forgoing dental care for economic reasons in Switzerland: a six-year cross-sectional population-based study

BACKGROUND: While oral health is part of general health and well-being, oral health disparities nevertheless persist. Potential mechanisms include socioeconomic factors that may influence access to dental care in the absence of universal dental care insurance coverage. We investigated the evolution, prevalence and determinants (including socioeconomic) of forgoing of dental care for economic reasons in a Swiss region, over the course of six years. METHODS: Repeated population-based surveys (2007-2012) of a representative sample of the adult population of the Canton of Geneva, Switzerland. Forgone dental care, socioeconomic and insurance status, marital status, and presence of dependent children were assessed using standardized methods. RESULTS: A total of 4313 subjects were included, 10.6% (457/4313) of whom reported having forgone dental care for economic reasons in the previous 12 months. The crude percentage varied from 2.4% in the wealthiest group (monthly income ≥ 13,000 CHF, 1 CHF ≈ 1$) to 23.5% among participants with the lowest income (<3,000 CHF). Since 2007/8, forgoing dental care remained stable overall, but in subjects with a monthly income of <3,000 CHF, the adjusted percentage increased from 16.3% in 2007/8 to 20.6% in 2012 (P trend = 0.002). Forgoing dental care for economic reasons was independently associated with lower income, younger age, female gender, current smoking, having dependent children, divorced status and not living with a partner, not having a supplementary health insurance, and receipt of a health insurance premium cost-subsidy. CONCLUSIONS: In a Swiss region without universal dental care insurance coverage, prevalence of forgoing dental care for economic reasons was high and highly dependent on income. Efforts should be made to prevent high-risk populations from forgoing dental care.

L'intégration de l'étranger dans la tragédie athénienne : remarques sur la Médée d'Euripide

Both the civic discourse and the religious ritual present in the festival of Great Dionysia make the question of foreigners and their integration a central issue for the Athenian tragedy. The self-image that Athens builds through the tragedy uses this theme to differentiate itself from barbarians and from other Greek cities. Nevertheless there are situations where the integration of the foreigner becomes problematic even in the tragic Athens. Such is in particular the case when the integration involves the marriage. This paper focuses on a case of incompatibility, by confronting the image of Athens in the third stasimon of Euripides' Medea and that of the infanticidal heroine.

An overlapping generations approach to price policies in privatehealthcare insurance. The Catalan case

We analyze premium policies and price dispersion among private healthcare insurance firms from an overlapping-generations model. The model shows that firms that apply equal premium to all policyholders and firms that set premiums according to the risk of insured can coexist in the short run, whereas coexistence is unlikely in the long run because it requires the coincidence of economic growth and interest rates. We find support for the model’s results in the Catalan health insurance industry. Keywords: Economic theory, price policies, health insurance, health economics, overlapping-generations.

How the West "invented" fertility restriction

We analyze the rise of the first socio-economic institution in history that limited fertility ? long before theDemographic Transition. The "European Marriage Pattern" (EMP) raised the marriage age of women andensured that many remained celibate, thereby reducing childbirths by up to one third between the 14thand 18th century. To explain the rise of EMP we build a two-sector model of agricultural production ?grain and livestock. Women have a comparative advantage in the latter because plow agriculture requiresphysical strength. After the Black Death in 1348-50, land abundance triggered a shift towards the landintensivepastoral sector, improving female employment prospects. Because women working in animalhusbandry had to remain unmarried, more farm service spelled later marriages. The resulting reductionin fertility led to a new Malthusian steady state with lower population pressure and higher wages. Themodel can thus help to explain the divergence in income per capita between Europe and Asia long beforethe Industrial Revolution. Using detailed data from England after 1290, we provide strong evidence forour mechanism. Where pastoral agriculture dominated, more women worked as servants, and marriageoccurred markedly later. Overall, we estimate that pastoral farming raised female ages at first marriage bymore than 4 years.

An application of capital allocation principles to operational risk

The cost of operational risk refers to the capital needed to a fford the loss generated by ordinary activities of a firm. In this work we demonstrate how allocation principles can be used to the subdivision of the aggregate capital so that the firm can distribute this cost across its various constituents that generate operational risk. Several capital allocation principles are revised. Proportional allocation allows to calculate a relative risk premium to be charged to each unit. An example of fraud risk in the banking sector is presented and some correlation scenarios between business lines are compared. Keywords: solvency, quantile, value at risk, copulas

Dots i llegats dels Baldrich de Valls (1768-1863)

Aquest article presenta les dificultats que van haver d’afrontar entre 1768 i 1863 els hereus de la casa Baldrich de Valls per liquidar els dots i les deixes testamentàries. Anton Baldrich Janer va nomenar hereu el fill gran del primer matrimoni amb l’obligació de pagar als seus germans i especialment als seus germanastres unes quantitats molt elevades de diners atorgats en un moment de grans expectatives econòmiques, gràcies al comerç amb Amèrica i el nord d’Europa. Durant la primera meitat del segle XIX, alguns anys de males collites, les contínues guerres i la independència de les colònies americanes feren minvar els recursos i van afeblir la hisenda familiar. Els successius hereus maldaven per pagar les contínues reclamacions dels cabalers i les cabaleres de les diferents generacions, fet que els impedia invertir en noves empreses per tal d’ampliar i modernitzar els seus negocis. L’any 1863, el darrer hereu Baldrich va morir sense descendència, havent pagat els darrers deutes familiars però sense haver creat nous horitzons per als seus successors.

Influence of label information on dark chocolate acceptability

The aim of the present work was to study how the information on product labels influences consumer expectations and their acceptance and purchase intention of dark chocolate. Six samples of dark choco- late, varying in brand (premium and store brand) and in type of product (regular dark chocolate, single cocoa origin dark chocolate and high percentage of cocoa dark chocolate), were evaluated by 109 con- sumers who scored their liking and purchase intention under three conditions: blind (only tasting the products), expected (observing product label information) and informed (tasting the products together with provision of the label information). In the expected condition, consumer liking was mainly affected by the brand. In the blind condition, differences in liking were due to the type of product; the samples with a high percentage of cocoa were those less preferred by consumers. Under the informed condition, liking of dark chocolates varied depending on both brand and type of product. Premium brand chocolates generated high consumer expectations of chocolate acceptability, which were fulfilled by the sensory characteristics of the products. Store brand chocolates created lower expectations, but when they were tasted they were as acceptable as premium chocolates. Claims of a high percentage of cocoa and single cocoa origin on labels did not generate higher expectations than regular dark chocolates.

Familial occurrence of an association of multiple intestinal atresia and choanal atresia: a new syndrome?

We report on two familial cases from a non-consanguineous marriage, presenting multiple intestinal and choanal atresia. Massive hydramnios and dilatation of the bowel were observed at 29 weeks of gestation during routine ultrasound scan of a healthy mother. The fetal karyotype was normal and cystic fibrosis screening was negative. Regular scans were performed throughout the pregnancy. The child was born at 34 weeks gestation. Choanal atresia was diagnosed at birth and abdominal investigations showed multiple atresia interesting both the small bowel and the colon. Further interventions were necessary because of recurrent obstructions. During the following pregnancy, a dilatation of the fetal intestinal tract was detected by ultrasonography at 27 weeks of gestation. Pregnancy was interrupted. Post-mortem examination of the fetus confirmed the stenosis of long segments of the small intestine associated with areas of colonic atresia. In both cases, histology and distribution were consistent with those reported in hereditary multiple intestinal atresia (HMIA). An association between multiple intestinal and choanal atresia has never been reported. We suggest it could correspond to a new autosomal recessive entity for which cytogenetic investigations and high-resolution array CGH revealed no visible anomalies.

Structural macro factors and the affine term structure of interest rates

This work consists of three essays investigating the ability of structural macroeconomic models to price zero coupon U.S. government bonds. 1. A small scale 3 factor DSGE model implying constant term premium is able to provide reasonable a fit for the term structure only at the expense of the persistence parameters of the structural shocks. The test of the structural model against one that has constant but unrestricted prices of risk parameters shows that the exogenous prices of risk-model is only weakly preferred. We provide an MLE based variance-covariance matrix of the Metropolis Proposal Density that improves convergence speeds in MCMC chains. 2. Affine in observable macro-variables, prices of risk specification is excessively flexible and provides term-structure fit without significantly altering the structural parameters. The exogenous component of the SDF is separating the macro part of the model from the term structure and the good term structure fit has as a driving force an extremely volatile SDF and an implied average short rate that is inexplicable. We conclude that the no arbitrage restrictions do not suffice to temper the SDF, thus there is need for more restrictions. We introduce a penalty-function methodology that proves useful in showing that affine prices of risk specifications are able to reconcile stable macro-dynamics with good term structure fit and a plausible SDF. 3. The level factor is reproduced most importantly by the preference shock to which it is strongly and positively related but technology and monetary shocks, with negative loadings, are also contributing to its replication. The slope factor is only related to the monetary policy shocks and it is poorly explained. We find that there are gains in in- and out-of-sample forecast of consumption and inflation if term structure information is used in a time varying hybrid prices of risk setting. In-sample yield forecast are better in models with non-stationary shocks for the period 1982-1988. After this period, time varying market price of risk models provide better in-sample forecasts. For the period 2005-2008, out of sample forecast of consumption and inflation are better if term structure information is incorporated in the DSGE model but yields are better forecasted by a pure macro DSGE model.

R&D poverty traps

In this paper we show that the R&D effort of a country and its economic growth are highly correlated. In order to analyze this relationship, we study the nature of the researching activity. In particular, we focus on the following characteristics of research: the inherent uncertainty of researching, the existence of a wage premium associated to innovative activities, and moral hazard. Assuming that a higher R&D effort translates into a higher R&D success probability, we show that when the R&D success probability is low, the economy is not willing to bear the risk associated to R&D activities. As a consequence, few researchers are hired and the economy stays in an R&D poverty trap, a situation where the economy is stacked in a low growth environment due to the uncertainty associated with the researching activity.
