Understanding the hierarchy governance choice of some wineries in Brazil - case study of 3 Brazilian wineries

ABSTRACT This study aims to contribute towards understanding the multiple factors, which influence firm's governance decisions. To identify some of these factors, three cases in the Brazilian wine industry were analyzed: Miolo located in Vale dos Vinhedos (South of Brazil) and in Vale do Rio São Francisco (Northeast of Brazil); Don Laurindo located in Vale dos Vinhedos; and ViniBrasil located in Vale do Rio São Francisco. For the most part, all three firms procure the grapes they use for their wine production in-house. Only Miolo purchases an insignificant amount of grapes outside of its production. By Brazilian standards, these regions have a long tradition of grape production and it is not difficult to purchase sufficient quantity of grapes to produce wine. However, the wineries are concerned also about the quality of the grapes they use and purchasing high-quality grapes might be critical issue. On the other hand, the quality of grapes is easily measured and the cost to buy in the market is cheaper than producing in-house. Furthermore, also the level of asset specificity present in the grape-grower-wine-producer transaction seems, by itself, insufficient to justify the use of hierarchical governance forms. Then, the aim of the article is to analyze the reasons why these wineries largely rely on hierarchy governance forms to procure their grape-inputs. What explains their use of hierarchy governance, given that both asset specificity and measurement problems appear to be relatively low?

Training effects with the observer-rated cognitive errors and the coping action patterns scales

The use of observer-rated scales requires that raters be trained until they have become reliable in using the scales. However, few studies properly report how training in using a given rating scale is conducted or indeed how it should be conducted. This study examined progress in interrater reliability over 6 months of training with two observer-rated scales, the Cognitive Errors Rating Scale and the Coping Action Patterns Rating Scale. The evolution of the intraclass correlation coefficients was modeled using hierarchical linear modeling. Results showed an overall training effect as well as effects of the basic training phase and of the rater calibration phase, the latter being smaller than the former. The results are discussed in terms of implications for rater training in psychotherapy research.

Selective inhibition of CTL activation by a dipalmitoyl-phospholipid that prevents the recruitment of signaling molecules to lipid rafts.

Antigen-specific T-cell activation implicates a redistribution of plasma membrane-bound molecules in lipid rafts, such as the coreceptors CD8 and CD4, the Src kinases Lek and Fyn, and the linker for activation of T cells (LAT), that results in the formation of signaling complexes. These molecules partition in lipid rafts because of palmitoylation of cytoplasmic, membrane proximal cysteines, which is essential for their functional integrity in T-cell activation. Here, we show that exogenous dipalmitoyl-phosphatidylethanolamine (DPPE), but not the related unsaturated dioleoyl-phosphatidylethanolamine (DOPE), partitions in lipid rafts. DPPE inhibits activation of CD8(+) T lymphocytes by sensitized syngeneic antigen-presenting cells or specific major histocompatibility complex (MHC) peptide tetramers, as indicated by esterase release and intracellular calcium mobilization. Cytotoxic, T lymphocyte (CTL)-target cell conjugate formation is not affected by DPPE, indicating that engagement of the T-cell receptor by its cognate ligand is intact in lipid-treated cells. In contrast to other agents known to block raft-dependent signaling, DPPE efficiently inhibits the MHC peptide-induced recruitment of palmitoylated signaling molecules to lipid rafts and CTL activation without affecting cell viability or lipid raft integrity.

Change in defense mechanisms and coping over the course of short-term dynamic psychotherapy for adjustment disorder.

Short-term dynamic psychotherapy (STDP) has rarely been investigated with regard to its underlying mechanisms of change, even if psychoanalytic theory informs us about several potential putative mechanisms of change in patients. Change in overall defensive functioning is one. In this study, we explored the role of overall defensive functioning, by comparing it on the process level with the neighbouring concept of overall coping functioning. A total of N=32 patients, mainly presenting adjustment disorder, were included in the study. The patients underwent STDP up to 40 sessions; three sessions per psychotherapy were transcribed and analyzed by using two observer-rating scales: Defense Mechanism Rating Scales (Perry, 1990) and Coping Action Patterns (Perry, Drapeau, Dunkley, & Blake, 2005). Hierarchical linear modeling was applied to model the change over the course of therapy and relate it to outcome. Results suggest that STDP has an effect on the target variable of overall defensive functioning, which was absent for overall coping functioning. Links with outcome confirm the importance of the effect. These results are discussed from methodological and clinical viewpoints.

Validation of the antenatal perceived stress inventory

This article presents the Antenatal Perceived Stress Inventory. The originality of this scale is to assess the impact of events experienced during pregnancy on the stress perceived by mothers. Scale validation was performed using data from 150 French-speaking nulliparous mothers and collected between 36 and 39 weeks of gestation (T1), and between 2 days (T2) and 6 weeks postpartum (T3). Factor analysis revealed a hierarchical three-factor structure that closely fit the data, including medical and obstetric risks/fetal health (F1), psychosocial changes (F2), and the prospect of childbirth (F3). The Antenatal Perceived Stress Inventory is a valid French prenatal stress scale with good psychometric properties.

Cognitive features in euthymic bipolar patients in old age.

OBJECTIVES: Studies of cognition in bipolar disorder (BD) have reported impairments in processing speed, working memory, episodic memory, and executive function, but they have primarily focused on young and middle-aged adults. In such studies, the severity of cognitive deficits increases with the duration of illness. Therefore, one would expect more pronounced deficits in patients with longstanding BD. The first aim of the present study was to determine the pattern and the magnitude of cognitive impairment in older euthymic BD patients. The second aim was to explore the interrelationship between these cognitive deficits and determine whether they reflect a single core impairment or the co-occurrence of independent cognitive deficits. METHODS: Twenty-two euthymic elderly BD patients and 22 controls, matched for gender, age, and education, underwent a comprehensive neuropsychological assessment. RESULTS: Compared to controls, BD patients had significantly reduced performance in processing speed, working memory, verbal fluency, and episodic memory, but not in executive function. Hierarchical regression analyses showed that verbal fluency and working memory impairments were fully mediated by changes in processing speed. This was not the case for the episodic memory dysfunction. CONCLUSION: The cognitive profile in older euthymic BD cases is similar to the one described in younger BD cohorts. Our results further suggest that impaired processing speed plays a major role in the cognitive changes observed in BD patients except for deficits in episodic memory, thus providing strong evidence that processing speed and episodic memory are two core deficits in elderly BD patients.

Performance of classic electrocardiographic criteria for left ventricular hypertrophy in an African population.

ECG criteria for left ventricular hypertrophy (LVH) have been almost exclusively elaborated and calibrated in white populations. Because several interethnic differences in ECG characteristics have been found, the applicability of these criteria to African individuals remains to be demonstrated. We therefore investigated the performance of classic ECG criteria for LVH detection in an African population. Digitized 12-lead ECG tracings were obtained from 334 African individuals randomly selected from the general population of the Republic of Seychelles (Indian Ocean). Left ventricular mass was calculated with M-mode echocardiography and indexed to body height. LVH was defined by taking the 95th percentile of body height-indexed LVM values in a reference subgroup. In the entire study sample, 16 men and 15 women (prevalence 9.3%) were finally declared to have LVH, of whom 9 were of the reference subgroup. Sensitivity, specificity, accuracy, and positive and negative predictive values for LVH were calculated for 9 classic ECG criteria, and receiver operating characteristic curves were computed. We also generated a new composite time-voltage criterion with stepwise multiple linear regression: weighted time-voltage criterion=(0.2366R(aVL)+0.0551R(V5)+0.0785S(V3)+ 0.2993T(V1))xQRS duration. The Sokolow-Lyon criterion reached the highest sensitivity (61%) and the R(aVL) voltage criterion reached the highest specificity (97%) when evaluated at their traditional partition value. However, at a fixed specificity of 95%, the sensitivity of these 10 criteria ranged from 16% to 32%. Best accuracy was obtained with the R(aVL) voltage criterion and the new composite time-voltage criterion (89% for both). Positive and negative predictive values varied considerably depending on the concomitant presence of 3 clinical risk factors for LVH (hypertension, age >/=50 years, overweight). Median positive and negative predictive values of the 10 ECG criteria were 15% and 95%, respectively, for subjects with none or 1 of these risk factors compared with 63% and 76% for subjects with all of them. In conclusion, the performance of classic ECG criteria for LVH detection was largely disparate and appeared to be lower in this population of East African origin than in white subjects. A newly generated composite time-voltage criterion might provide improved performance. The predictive value of ECG criteria for LVH was considerably enhanced with the integration of information on concomitant clinical risk factors for LVH.

A better understanding of ecological conditions for Leontopodium alpinum Cassini in the Swiss Alps

Although Leontopodium alpinum is considered to be threatened in many countries, only limited scientific information about its autecology is available. In this study, we aim to define the most important ecological factors which influence the distribution of L. alpinum in the Swiss Alps. These were assessed at the national scale using species distribution models based on topoclimatic predictors and at the community scale using exhaustive plant inventories. The latter were analysed using hierarchical clustering and principal component analysis, and the results were interpreted using ecological indicator values. L. alpinum was found almost exclusively on base-rich bedrocks (limestone and ultramaphic rocks). The species distribution models showed that the available moisture (dry regions, mostly in the Inner Alps), elevation (mostly above 2000 m.a.s.l.) and slope (mostly >30°) were the most important predictors. The relevés showed that L. alpinum is present in a wide range of plant communities, all subalpine-alpine open grasslands, with a low grass cover. As a light-demanding and short species, L. alpinum requires light at ground level; hence, it can only grow in open, nutrient-poor grasslands. These conditions are met in dry conditions (dry, summer-warm climate, rocky and draining soil, south-facing aspect and/or steep slope), at high elevations, on oligotrophic soils and/or on windy ridges. Base-rich soils appear to also be essential, although it is still unclear if this corresponds to physiological or ecological (lower competition) requirements.

Proteomic analysis of mononuclear cells of patients with minimal-change nephrotic syndrome of childhood.

Background/Aims. Recently, peripheral blood mononuclear cell transcriptome analysis has identified genes that are upregulated in relapsing minimal-change nephrotic syndrome (MCNS). In order to investigate protein expression in peripheral blood mononuclear cells (PBMC) from relapsing MCNS patients, we performed proteomic comparisons of PBMC from patients with MCNS in relapse and controls. METHODS: PBMC from a total of 20 patients were analysed. PBMC were taken from five patients with relapsing MCNS, four in remission, five patients with other glomerular diseases and six controls. Two dimensional electrophoresis was performed and proteome patterns were compared. RESULTS: Automatic heuristic clustering analysis allowed us to pool correctly the gels from the MCNS patients in the relapse and in the control groups. Using hierarchical population matching, nine spots were found to be increased in PBMC from MCNS patients in relapse. Four spots were identified by mass spectrometry. Three of the four proteins identified (L-plastin, alpha-tropomyosin and annexin III) were cytoskeletal-associated proteins. Using western blot and immunochemistry, L-plastin and alpha-tropomyosin 3 concentrations were found to be enhanced in PBMC from MCNS patients in relapse. Conclusions. These data indicate that a specific proteomic profile characterizes PBMC from MCNS patients in relapse. Proteins involved in PBMC cytoskeletal rearrangement are increased in relapsing MCNS. We hypothesize that T-cell cytoskeletal rearrangement may play a role in the pathogenesis of MCNS by altering the expression of cell surface receptors and by modifying the interaction of these cells with glomerular cells.

Efectos de la aplicación de cenizas de caldera de biomasa en el modelo jerárquico de agregación de un suelo forestal bajo condiciones oceánicas

Se ha estudiado los efectos que tiene la aplicación de cenizas de caldera de biomasa, en el modelo jerárquico de agregación (Tisdall y Oades, 1982) y en la estabilización del C orgánico en un suelo forestal situado en la zona templada del País Vasco. Para ello, se aplicaron 3 tratamientos con diferentes dosis de ceniza en muestras de suelo tamizadas a 250 μm procedentes de un huerto semillero de pinus radiata. Estas muestras fueron incubadas durante 3 meses y fraccionadas los días 29, 44, 64, 78 y 92 con la intención de separar los macroagregados grandes (LMagg), de los macroagregados pequeños (Magg), microagregados (magg), limos (silt) y arcillas (clay). Todas las fracciones fueron analizadas para determinar su contenido en C orgánico. Los resultados mostraron que con la aplicación de cenizas, el modelo jerárquico de agregación de suelo se cumple para las fracciones LMagg, Magg y magg, pero no para la fracción silt. Además se ha observado que las cenizas promueven la formación de microagregados aumentado así la capacidad de secuestro de C del suelo, pero en cambio disminuye la proporción de macroagregados, hecho que podría acarrear una disminución en la calidad estructural del suelo.

Efectos de la aplicación de biochar en el modelo jerárquico de agregación de un suelo forestal bajo condiciones oceánicas

El objetivo del presente proyecto ha sido estudiar los efectos del biochar en el modelo jerárquico de agregación del suelo. Para estudiar estas propiedades se ha realizado una incubación de tres tratamientos de biochar Miscanthus (biochar 10t/ha (B10), 2t/ha (B2) y 10t/ha+Nitrógeno (BN), durante 91 días, realizando fraccionamientos en húmedo de las muestras los días 28, 43, 63, 77 y 91. En estos fraccionamientos se han separado las fracciones macroagregrado (LMagg+Magg), microagregados (magg), limos (Silt) y arcillas (Clay). Por último se determinó el C orgánico de todas las fracciones de los tratamientos obtenidos con el objeto de obtener información sobre el efecto que puede tener la aplicación del biochar sobre la estabilización de C en las fracciones del suelo. Los resultados obtenidos indican que con la aplicación de biochar, la teoría jerárquica de agregación propuesta por Tisdall y Oades (1982), no se cumple en la dinámica de agregación del suelo, si bien se puede observar una jerarquía en la estabilización del C orgánico en los macroagregados y microagregados. Además las dosis altas de biochar producen mayor cantidad de microagregados, favoreciendo el secuestro de C en el suelo. Por otro lado, con dosis altas de biochar se aprecia una disminución de la fracción de macroagregados, hecho que puede influir negativamente en la estructura del suelo.

Ab initio benchmark study for the oxidative addition of CH4 to Pd: importance of basis-set flexibility and polarization

To obtain a state-of-the-art benchmark potential energy surface (PES) for the archetypal oxidative addition of the methane C-H bond to the palladium atom, we have explored this PES using a hierarchical series of ab initio methods (Hartree-Fock, second-order Møller-Plesset perturbation theory, fourth-order Møller-Plesset perturbation theory with single, double and quadruple excitations, coupled cluster theory with single and double excitations (CCSD), and with triple excitations treated perturbatively [CCSD(T)]) and hybrid density functional theory using the B3LYP functional, in combination with a hierarchical series of ten Gaussian-type basis sets, up to g polarization. Relativistic effects are taken into account either through a relativistic effective core potential for palladium or through a full four-component all-electron approach. Counterpoise corrected relative energies of stationary points are converged to within 0.1-0.2 kcal/mol as a function of the basis-set size. Our best estimate of kinetic and thermodynamic parameters is -8.1 (-8.3) kcal/mol for the formation of the reactant complex, 5.8 (3.1) kcal/mol for the activation energy relative to the separate reactants, and 0.8 (-1.2) kcal/mol for the reaction energy (zero-point vibrational energy-corrected values in parentheses). This agrees well with available experimental data. Our work highlights the importance of sufficient higher angular momentum polarization functions, f and g, for correctly describing metal-d-electron correlation and, thus, for obtaining reliable relative energies. We show that standard basis sets, such as LANL2DZ+ 1f for palladium, are not sufficiently polarized for this purpose and lead to erroneous CCSD(T) results. B3LYP is associated with smaller basis set superposition errors and shows faster convergence with basis-set size but yields relative energies (in particular, a reaction barrier) that are ca. 3.5 kcal/mol higher than the corresponding CCSD(T) values

Phylogeny of shrews (Soricidae) : taxonomic and biogeographic implications

Résumé Les Soricidae sont l'une des plus grandes familles de mammifères avec plus de 300 espèces décrites. Elle a été récemment divisée en trois sous-familles, les Soricidae, qui sont distribuées dans la région Holarctique, les Crocidurinae en Afrique et en Eurasie, et les Myosoricinae en Afrique. La diversité spécifique de cette famille a conduit à des interprétations taxonomiques multiples, qui sont à l'origine de polémiques entre spécialistes, et même les premiers résultats moléculaires ont été fortement contradictoires. Le but de cette thèse est donc d'appliquer des meilleures techniques sur des échantillons mieux ciblés, afin de résoudre les contradictions taxonomiques et comprendre l'histoire de cette famille. Par le biais de marqueurs génétiques mitochondriaux et nucléaires, j'ai étudié: (i) Les relations taxonomiques à différent niveaux hiérarchiques au sein des Soricidae, c'est-à dire, entre les sous-familles, tribus, et genres, ainsi qu'au sein de deux complexes d'espèces largement distribués, et d'une espèce européenne, le but étant d'établir la congruence entre les données génétiques et les interprétations morphologiques classiques. (ii) Les relations biogéographiques, soit l'origine potentielle des différentes sous-familles, tribus, et genres, le nombre d'échanges intercontinentaux, ainsi que la structure phylogéographique à un niveau (péri)-spécifique, afin d'établir l'histoire de la diversification de cette famille. Les analyses combinées d'ADN mitochondrial et nucléaire ont montré un rapport clair entre les taxa à un niveau taxonomique élevé, mettant en évidence les rapports entre les sous-familles, les tribus, et les genres. Bien que Myosorex constitue un groupe monophylétique distinct, sa définition en tant que sous-famille séparée ne peut pas être reconnue. Ainsi, nous proposons d'attribuer un niveau de tribu pour ce clade (inclus dans les Crocidurinae). Nous avons également montré l'inclusion du genre Anourosorex dans les Soricinae et non en position basale dans les Soricidae. Au sein des Crocidurinae, Suncus s'est révélé être paraphylétique, et le genre Diplomesodon devrait être considéré d'un point de vue génétique comme invalide, puisque il se trouve au sein du clade du genre Crocidura. À un niveau taxonomique plus bas, nous avons montré la monophylie de deux complexes d'espèces largement distribués, le groupe de C. suaveolens et de C. olivieri. Néanmoins à l'intérieur de ceux-ci, des différences majeures avec la classification morphologique se sont révélées. Par exemples, C. sibirica n'est pas une espèce valide, les analyses de phylogénie moléculaire ne montrant pas de variations génétiques entre celle-ci et un échantillon de la localité type de C. suaveolens. D'un point de vue biogéographique, les fluctuations climatiques et les activités tectoniques des 20 derniers millions d'années ont fortement influencé la diversité actuelle des Soricidae. À un niveau taxonomique élevé, l'apparition de connexions de terre temporaires entre le Vieux et le Nouveau Monde au Miocène moyen ont mené à plusieurs colonisations indépendantes de l'Amérique par les Soricinae. Celles-ci ónt conduit à une diversification d'une tribu (Notiosoricini), ainsi que de genres (par ex: Cryptotis, Blarina) et d'un sous-genre (Otisorex) endémique au Néarctique. Dans le Vieux Monde, les barrières entre l'Afrique et Eurasie étaient plus perméables, menant à plusieurs échanges bidirectionnels de Crocidurinae. La diversification des clades principaux s'est produite au Miocène, certains clades étant endémiques d'Afrique ou d'Eurasie, tandis que d'autres se sont diversifiés à travers le Vieux Monde. À un niveau spécifique ou péri-spécifique, la fluctuation climatique du Pliocène et les glaciations du Pléistocène ont fortement divisé les populations dans tout le Paléarctique, menant à des entités génétiques distinctes. En Europe, les populations du groupe de C. suaveolens ont été divisées en une lignée Sud-Ouest et une Sud-Est, alors qu'au Proche-Orient et au Moyen-Orient, la diversité de clades est plus importante. En conclusion, mes études ont révélé que du Miocène à nos jours, la diversification des Soricidae a été provoquée par la colonisation de nouveaux habitats (dispersion), ainsi que par l'isolement des populations par diverses barrières (vicariance). Abstract The Soricidae is one of the largest mammalian families with more than 300 species described. It has been recently divided into three subfamilies, the Soricinae, which are distributed in the Holartic region, the Crocidurinae in Africa and Eurasia, and the Myosoricinae in Africa. The specific diversity of this family have led to multiple systematic interpretations and controversies between authors. Fortunately, today, cytotaxonomic, allozymic and molecular studies have permitted to clarify some uncertainties. Nevertheless, the Soricidae remains still poorly known. In this thesis, we aim at understanding with the use of mitochondrial and nuclear markers: (i) the taxonomic relationships at different hierarchical levels within Soricidae, i.e., between the subfamilies, tribes, and genera, as well as within two largely distributed species complexes, and within a European species, the goal being to establish congruence between the genetic data and traditional morphological interpretations; (ii) the biogeographic relationships, especially the potential origin of the different subfamilies, tribes, and genera, the number of transcontinental exchanges, as well as the phylogeographic structure at a (peri)-specific level, in order to establish the history of the genetic diversification of this family. The combined analyses of mitochondrial and nuclear DNA highlight for the first time a clear relationship between taxa at a high taxonomical level, permitting to distinguish the relationships between subfamilies, tribes, and genera. Although Myosorex formed a distinct monophyletic group, its definition as a distinct sub-family cannot be advocated. Thus, we propose to attribute a tribe level for this Glade (included within the Crocidurinae). Additionally, this combination of genes pleads in favour of the inclusion of the genus Anourosorex within the Soricinae and not in a basal position within the Soricidae. Within the Crocidurinae, Suncus appeared to be paraphyletic, and Diplomesodon should be considered from a genetic point of view as invalid, and is presently considered as Crocidura. At a lower taxonomic level, we showed the monophyly of two widely distributed species complexes, the C. suaveolens group and the C. olivieri group. Nevertheless within those, we showed major differences compared to morphological classification. For examples, C. sibirica revealed to not be a valid species, the molecular phylogenetic analyses failed to evidence genetical variations between it and samples of the type locality of C. suaveolens. In a biogeographic point of view, the climatic fluctuations and the tectonic plate activities of the last 20 Myr have strongly influenced the actual diversity of the family. At a high taxonomic level, the successive land bridge connections between the Old and the New World, which occurred during the Middle Miocene, have led to several independent colonisations of America by Soricinae, and a subsequent diversification of endemic Nearctic's tribe (Notiosoricini), genera (e.g. Cryptotis, Blaring) and sub-genus (Otisorex) within the Soricinae. Within the Old World, the barriers between Africa and Eurasia were more permeable, leading to several bidirectional exchanges within the Crocidurinae. The diversification of major clades occurred through the Miocene, some clades being endemic to Africa or Eurasia, whereas others diversified through the Old World. At a species level or a peri-specific level, the Pliocene climatic fluctuation and the Pleistocene glaciations have strongly divided the populations throughout the Palaearctic, leading to well defined genetic entities. In Europe, populations of the C. suaveolens group were split in a classical south-western and south-eastern lineage. In contrast, the Near East and the Middle East reveal many differentiated clades. In conclusion, our studies revealed that, from the Miocene to present, the diversification and speciation events within the Soricidae were caused by natural colonisation of new habitats (dispersion) and isolation of populations by various barriers (vicariance).

Neuron-to-neuron wild-type Tau protein transfer through a trans-synaptic mechanism: relevance to sporadic tauopathies.

BACKGROUND: In sporadic Tauopathies, neurofibrillary degeneration (NFD) is characterised by the intraneuronal aggregation of wild-type Tau proteins. In the human brain, the hierarchical pathways of this neurodegeneration have been well established in Alzheimer's disease (AD) and other sporadic tauopathies such as argyrophilic grain disorder and progressive supranuclear palsy but the molecular and cellular mechanisms supporting this progression are yet not known. These pathways appear to be associated with the intercellular transmission of pathology, as recently suggested in Tau transgenic mice. However, these conclusions remain ill-defined due to a lack of toxicity data and difficulties associated with the use of mutant Tau. RESULTS: Using a lentiviral-mediated rat model of hippocampal NFD, we demonstrated that wild-type human Tau protein is axonally transferred from ventral hippocampus neurons to connected secondary neurons even at distant brain areas such as olfactory and limbic systems indicating a trans-synaptic protein transfer. Using different immunological tools to follow phospho-Tau species, it was clear that Tau pathology generated using mutated Tau remains near the IS whereas it spreads much further using the wild-type one. CONCLUSION: Taken together, these results support a novel mechanism for Tau protein transfer compared to previous reports based on transgenic models with mutant cDNA. It also demonstrates that mutant Tau proteins are not suitable for the development of experimental models helpful to validate therapeutic intervention interfering with Tau spreading.

Gender inequality in health among elderly people in a combined framework of socioeconomic position, family characteristics and social support

This study analyses gender inequalities in health among elderly people in Catalonia (Spain) by adopting a conceptual framework that globally considers three dimensions of health determinants : socio-economic position, family characteristics and social support. Data came from the 2006 Catalonian Health Survey. For the purposes of this study a sub-sample of people aged 65–85 years with no paid job was selected (1,113 men and 1,484 women). The health outcomes analysed were self-perceived health status, poor mental health status and long-standing limiting illness. Multiple logistic regression models separated by sex were fitted and a hierarchical model was fitted in three steps. Health status among elderly women was poorer than among the men for the three outcomes analysed. Whereas living with disabled people was positively related to the three health outcomes and confidant social support was negatively associated with all of them in both sexes, there were gender differences in other social determinants of health. Our results emphasise the importance of using an integrated approach for the analysis of health inequalities among elderly people, simultaneously considering socio-economic position, family characteristics and social support, as well as different health indicators, in order fully to understand the social determinants of the health status of older men and women.
