Flota de arrastre de fondo de menor escala en la Región Tumbes

Los problemas críticos de la pesquería de arrastre de menor escala, son las capturas de ejemplares juveniles, alta presencia de descartes, pesca incidental o accesoria y conflictos con los pescadores artesanales que usan redes de enmalle cortineras. En toda la zona de estudio, los índices de captura por unidad de esfuerzo (CPUE) fue 142,4 kg/h y 477,5 kg/lance, bycatch por unidad de esfuerzo (BPUE) fue 27,2 kg/h y 91,1 kg/lance. Los mayores CPUE fueron en la zona sur dentro de las 5 mn con 199,0 kg/h y 617,8 kg/lance. La composición de la captura relativa al peso estuvo dominada por el falso volador (Prionotus stephanophrys, 24,6%) y carajito (Diplectrum conceptione, 21,4%). Las especies incidentales más importantes fueron espejo (Selene peruviana, 9,8%), bereche (Larimus pacificus, 9,3%), cachema (Cynoscion analis, 4,0%), chiri (Peprilus medius, 2,9%), lenguado de boca chica (Etropus ectenes, 2,5%), doncella (Hemanthias peruanus, 2,1%). El descarte fue 19,1% de la captura, los principales recursos fueron merluza (Merluccius gayi peruanus, 39,1%), lengüeta (Symphurus sechurae, 10,9%), morena (Muraena clepsidra, 4,9%), pez hojita (Chloroscombrus orqueta, 4,8%), otras especies 31,5% (incluyendo restos de peces y equinodermos). El índice de impacto al ecosistema marino fue de 3,7 (1: no favorable al 10: favorable). Por lo que es un arte de pesca no amigable con el ecosistema marino que no debe usarse dentro del área costera

Que promettent les styles d'interactions? Une approche sociologique de l'intimité conjugale

This article intends to grasp the stabilization process, deterioration or improvement of the conjugal intimacy over five years, based on a representative sample of couples living in Switzerland. The dynamics develop in different ways depending on the degree of autonomy of the partners, the gendering of household tasks, conjugal openess and the coping strategies of the couples.

Vocal sib-sib interactions: how siblings adjust signaling level to each other

Game theory states that iterative interactions between individuals are necessary to adjust behaviour optimally to one another. Although our understanding of the role of begging signals in the resolution of parent-offspring conflict over parental investment rests on game theory implying repeated interactions between family members, empiricists usually consider interactions at the exact moment when parents allocate food among the brood. Therefore, the mechanisms by which siblings adjust signalling level to one another remain unclear. We tackled this issue in the barn owl, Tyto alba. In the absence of parents, hungry nestlings signal vocally to siblings their intention to contest vigorously the next, indivisible, food item. Such behaviour deters siblings from competing and begging when parents return to the nest. In experimental two-chick broods, nestlings producing the longest calls in the absence of parents, a signal of hunger level, were more successful at monopolizing the food item at the first parental feeding visit of the night. Moreover, nestlings increased (versus decreased) call duration when their sibling produced longer (versus shorter) calls, and an individual was more likely to call again if its sibling began to vocalize before or just after it had ended its previous call. These results are in agreement with the hypothesis that siblings challenge each other vocally to reinforce the honesty of sib-sib communication and to resolve conflicts over which individual will have priority of access to the next delivered food item. Siblings challenge each other vocally to confirm that the level of signalling accurately reflects motivation.

De la clinique à la recherche dans un centre de thérapie de couple et de famille

From practice to research in a couple and family therapy consultation - This article presents a study that took place at a Couples and Family outpatient clinic. Multiple levels are involved in couples and family therapy. The definition of relevant variables allowing the evaluation of a systemic therapeutic intervention's efficiency is thus particularly difficult. The aim of our study is to assess the short- and medium-term evolution on four different levels: (1) individual symptomatology; (2) conjugal satisfaction; (3) parental and co-parental relationship quality, and (4) global family functioning for a brief systemic intervention (BSI). BSI consists in a therapeutic treatment of a maximum of six sessions. The different levels are assessed by validated self-reported questionnaires before and after BSI as well as at a three-month follow-up. The therapeutic alliance is also measured by a self-reported questionnaire (WAI) after each session. The results of a pilot sample of N = 10 couples and families showed the efficiency of BSI on most of the variables measured and a greater therapeutic change for women than for men. No therapeutic effect was observed for men's individual symptomatology or for global family functioning. These results suggest that BSI has a different impact on the four levels measured. The importance of the therapeutic alliance on the therapeutic success is also confirmed.

L' Impacte de la mort en estudiants d'infermeria durant el seu primer període de pràctiques

La mort i el procés de morir són fets quotidians en les persones grans i, conseqüentment, en els centres sociosanitaris, on bona part de les persones usuàries són d’edat avançada. Tot i que es tracta d’un fenomen natural que s’inclou dins del cicle vital de les persones, en la nostra societat la mort encara provoca rebuig, por, ansietat, tristesa i inquietud. En aquest marc, les estudiants1 d’infermeria són un col·lectiu que poden patir especialment l’impacte de la mort. Primer, perquè com a membres de la societat tenen interioritzat el codi social preestablert envers aquest tema i, segon, perquè durant la seva formació estan en contacte amb persones que estan al final de la vida i poden presenciar vivències de mort. En el primer període de pràctiques dels estudis d’infermeria, les estudiants han de fer front a diverses situacions del dia a dia fins aleshores desconegudes. Els conflictes interpersonals amb l'equip de treball i la inseguretat sobre les habilitats i les competències professionals són alguns dels aspectes que acostumen a viure amb més tensió. Tot i això, el que més impacte els provoca és la cura de les persones al final de la vida. Davant d'una situació de tensió, la persona viu un component estressor, que suposa el punt d’inflexió. A partir d’aquí s’activen els components adaptatius, que és el que emocionalment fa que la persona pugui fer front a aquesta situació estressant. A més, hi ha un component de suport, que són les ajudes que té. Segons com es treballi el component adaptatiu farà que la persona reaccioni en un futur de forma més automàtica i inconscient o, al contrari, que la persona respongui de forma més conscient i intencionada. El present treball està concebut per comprendre quins elements psicosocials – components estressors i components de suport– poden afectar a les estudiants que presencien la vivència de la mort de malalts geriàtrics terminals en el primer període de pràctiques en un centre sociosanitari. S’ha dissenyat un estudi descriptiu transversal quantitatiu, de caràcter exploratori, per tal de descriure la freqüència i algunes característiques psicosocials al voltant de la mort en estudiants d'infermeria en el seu primer període de pràctiques, tant a nivell personal com a nivell professional. La mostra de l'estudi són 65 estudiants, la majoria són dones d'entre els 18 i els 29 anys –més d’un 90%–. Els resultats indiquen que un 80% dels futurs professionals estudiats han patit la mort d’alguna persona significativa al llarg de la seva vida; d'aquests, gairebé un de cada quatre presenta dol complicat. Quant a la vivència de mort en les pràctiques, el 83% l'ha experimentat. Tot i aquest elevat percentatge, no totes les experiències tenen una connotació negativa. En prop de la meitat dels casos, les morts són percebudes com una experiència enriquidora i natural. Els components estressors més impactants que les estudiants han viscut durant les pràctiques per la mort d’alguna persona malalta són: la reacció de la família del finat, el patiment que es genera al seu voltant, algun signe o símptoma físic experimentat pel malalt al final del procés, i la pròpia reacció emocional. Els components de suport expressats són: saber gestionar les pròpies emocions, tenir més formació sobre relació d’ ajuda i empatia, tenir més formació en control de símptomes i comunicació, per atendre usuaris –tant malalts com familiars- i que algú els informés i orientés en el procés. Altres resultats a tenir en compte són que la població estudiada té més preocupació o inquietud per la mort i el procés de morir de la persona estimada i menys per la pròpia mort. A més, tot i que la meitat no hagués escollit geriatria com opció a les primeres pràctiques clíniques, gairebé tot el grup estudiat ho recomanaria després d'haver viscut l'experiència. Les implicacions pràctiques d'aquest estudi porten a pensar que es pot reorientar la informació i preparació que es dóna a les estudiants d’infermeria abans del primer contacte amb la realitat dels centres sociosanitaris, així com també el paper de formació i suport que pot fer tant la persona tutora de pràctiques com les infermeres de referència dels diferents centres. En conclusió, caldria dissenyar estratègies formatives i de suport entorn a la preparació psicològica personal de l’estudiant; entorn a l’acompanyament, les cures pal·liatives i el dol; i valorar la seva eficiència en el futur.

Psychotherapeutic case conceptualization using plan analysis for bipolar affective disorder.

Valid individualized case conceptualization methodologies, such as plan analysis, are rarely used for the psychotherapeutic treatment conceptualization and planning of bipolar affective disorder (BD), even if data do exist showing that psychotherapy interventions might be enhanced by applying such analyses for treatment planning for several groups of patients. We applied plan analysis as a research tool (Caspar, 1995) to N=30 inpatients presenting BD, who were interviewed twice. Our study aimed at producing a prototypical plan structure encompassing the most relevant data from the 30 individual case conceptualizations. Special focus was given to links with emotions and coping plans. Inter-rater reliability of these plan analyses was considered sufficient. Results suggest the presence of two subtypes based on plananalytic principles: emotion control and relationship control, along with a mixed form. These subtypes are discussed with regard to inherent plananalytic conflicts, specific emotions and coping plans, as well as symptom level and type. Finally, conclusions are drawn for enhancing psychotherapeutic practice with BD patients, based on the motive-oriented therapeutic relationship.

Politique et réseaux. Logiques de la mobilisation politique populaire dans une vallée alpine 1839-1900

Résumé: Depuis plusieurs années, le thème des réseaux sociaux est au centre de l'intérêt des études historiques. Est-il possible de formaliser l'analyse de réseaux sociaux spécifiques - parenté, clientèle, solidarités locales, etc. - afin d'en analyser l'influence sur des événements historiques et des individus précis ? L'étude présentée prend en considération les luttes souvent violentes entre radicaux et conservateurs dans le Val de Bagnes, en Valais (Suisse), entre 1839 et 1900. La comparaison entre les généalogies des familles de la vallée et les informations sur la vie politique et sociale nous permet de relever l'influence de la parenté dans l'organisation des factions politiques. Les réseaux de parenté sont toutefois ouverts et souples, permettant des adaptations aux évolutions de la situation politique, économique et sociale. L'affaire autour du faux-monnayeur italien Joseph S. Farinet, dans les années 1870, nous permet par exemple de suivre l'évolution des réseaux de solidarité, à la suite d'une crise politique, ainsi que l'émergence de nouvelles activités économiques, notamment le tourisme, avec les hôteliers, les aubergistes et les guides de montagne souvent liés au milieu radical. L'analyse permet également de nuancer l'influence des réseaux de patronage : les collaborations horizontales, à l'intérieur des classes populaires, semblent mieux expliquer les solidarités politiques. Abstract: For several years, historians have been closely concerned with the question of social networks. Is it possible to conceptualize specific networks - like kinship, patronage or local solidarities - and to analyze their influence on concrete individuals or historical events? This paper considers the violent struggles between a radical political faction and a conservative one in a Swiss alpine valley, the Val de Bagnes (Valais) between 1839 and 1900. It compares information about political and social conflicts in the valley with genealogies of local families. By this way the eminent influence of kinship ties on political organizations becomes visible. But kinship networks are open and very supple, allowing adaptations to new political and social configurations. The trials against the Italian smuggler and counterfeiter Joseph S. Farinet in the Seventies allow to describe the evolution of local cooperation networks as a consequence of a political crisis in the canton of Valais and of new economic activities. The paper stresses the active role of a emerging group of hotel- or inn-owners and mountain guides, often closely tied with the radical milieu. The analysis of social transactions raises critical questions about the role of patronage in political mobilization: horizontal cooperation and kinship ties between peasants, small cattle owners and artisans seem to explain political solidarities better than patronage structures.

Integration of teacher education into the Swiss higher education system

The integration of specific institutions for teacher education into the higher education system represents a milestone in the Swiss educational policy and has broad implications. This thesis explores organizational and institutional change resulting from this policy reform, and attempts to assess structural change in terms of differentiation and convergence within the system of higher education. Key issues that are dealt with are, on the one hand, the adoption of a research function by the newly conceptualized institutions of teacher education, and on the other, the positioning of the new institutions within the higher education system. Drawing on actor-centred approaches to differentiation, this dissertation discusses system-level specificities of tertiarized teacher education and asks how this affects institutional configurations and actor constellations. On the basis of qualitative and quantitative empirical data, a comparative analysis has been carried out including case studies of four universities of teacher education as well as multivariate regression analysis of micro-level data on students' educational choices. The study finds that the process of system integration and adaption to the research function by the various institutions have unfolded differently depending on the institutional setting and the specific actor constellations. The new institutions have clearly made a strong push to position themselves as a new institutional type and to find their identity beyond the traditional binary divide which assigns the universities of teacher education to the college sector. Potential conflicts have been identified in divergent cognitive normative orientations and perceptions of researchers, teacher educators, policy-makers, teachers, and students as to the mission and role of the new type of higher education institution. - L'intégration dans le système d'enseignement supérieur d'institutions qui ont pour tâche spécifique de former des enseignants peut être considérée comme un événement majeur dans la politique éducative suisse, qui se trouve avoir des conséquences importantes à plusieurs niveaux. Cette thèse explore les changements organisationnels et institutionnels résultant de cette réforme politique, et elle se propose d'évaluer en termes de différentiation et de convergence les changements structurels intervenus dans le système d'éducation tertiaire. Les principaux aspects traités sont d'une part la nouvelle mission de recherche attribuée à ces institutions de formation pédagogique, et de l'autre la place par rapport aux autres institutions du système d'éducation tertiaire. Recourant à une approche centrée sur les acteurs pour étudier les processus de différen-tiation, la thèse met en lumière et en discussion les spécificités inhérentes au système tertiaire au sein duquel se joue la formation des enseignants nouvellement conçue et soulève la question des effets de cette nouvelle façon de former les enseignants sur les configurations institutionnelles et les constellations d'acteurs. Une analyse comparative a été réalisée sur la base de données qualitatives et quantitatives issues de quatre études de cas de hautes écoles pédagogiques et d'analyses de régression multiple de données de niveau micro concernant les choix de carrière des étudiants. Les résultats montrent à quel point le processus d'intégration dans le système et la nouvelle mission de recherche peuvent apparaître de manière différente selon le cadre institutionnel d'une école et la constellation spécifique des acteurs influents. A pu clairement être observée une forte aspiration des hautes écoles pédagogiques à se créer une identité au-delà de la structure binaire du système qui assigne la formation des enseignants au secteur des hautes écoles spéciali-sées. Des divergences apparaissent dans les conceptions et perceptions cognitives et normatives des cher-cheurs, formateurs, politiciens, enseignants et étudiants quant à la mission et au rôle de ce nouveau type de haute école. - Die Integration spezieller Institutionen für die Lehrerbildung ins Hochschulsystem stellt einen bedeutsamen Schritt mit weitreichenden Folgen in der Entwicklung des schweizerischen Bildungswesens dar. Diese Dissertation untersucht die mit der Neuerung verbundenen Veränderungen auf organisatorischer und institutioneller Ebene und versucht, die strukturelle Entwicklung unter den Gesichtspunkten von Differenzierung und Konvergenz innerhalb des tertiären Bildungssystems einzuordnen. Zentrale Themen sind dabei zum einen die Einführung von Forschung und Entwicklung als zusätzlichem Leistungsauftrag in der Lehrerbildung und zum andern die Positionierung der pädagogischen Hochschulen innerhalb des Hochschulsystems. Anhand akteurzentrierter Ansätze zur Differenzierung werden die Besonderheiten einer tertiarisierten Lehrerbildung hinsichtlich der Systemebenen diskutiert und Antworten auf die Frage gesucht, wie die Reform die institutionellen Konfigurationen und die Akteurkonstellationen beeinflusst. Auf der Grundlage qualitativer und quantitativer Daten wurde eine vergleichende Analyse durchgeführt, welche Fallstudien zu vier pädagogischen Hochschulen umfasst sowie Regressionsanalysen von Mikrodaten zur Studienwahl von Maturanden. Die Ergebnisse machen deutlich, dass sich der Prozess der Systemintegration und die Einführung von Forschung in die Lehrerbildung in Abhängigkeit von institutionellen Ordnungen und der jeweiligen Akteurkonstellation unterschiedlich gestalten. Es lässt sich bei den neu gegründeten pädagogischen Hochschulen ein starkes Bestreben feststellen, sich als neuen Hochschultypus zu positionieren und sich eine Identität zu schaffen jenseits der herkömmlichen binären Struktur, welche die pädagogischen Hochschulen dem Fachhochschul-Sektor zuordnet. Potentielle Konflikte zeichnen sich ab in den divergierenden kognitiven und normativen Orientierungen und Wahrnehmungen von Forschern, Ausbildern, Bildungspolitikern, Lehrern und Studierenden hinsichtlich des Auftrags und der Rolle dieses neuen Typs Hochschule.

Cetuximab In Combination With Docetaxel In Patients (Pts) With Metastatic Castration Resistant (Mcrpc) And Docetaxel-Refractory Prostate Cancer: Final Analysis Of The Multicenter Phase Ii Trial Sakk 08/07

There is no registered treatment (ttr) for pts with mCRPC who have progressive disease during or shortly after docetaxel (doc). EGFR overexpression increases in prostate cancer during the course of the disease. We investigated efficacy and safety of the combination of the monoclonal EGFR antibody cetuximab (cet) and doc in pts with mCRPC who are doc-refractory. Methods: Pts with mCRPC progressing during or < 90 days after at least 12 weeks of doc were included. Ttr consisted of the same doc regimen as prior to progression (35mg/m2 d1,8,15 q4w or 75mg/m2 q3w) in combination with cet (400mg/m2 d1, then 250mg/m2 weekly). Primary endpoint was progression free survival (PFS) at 12 weeks defined as absence of PSA progression or progression of metastases (mets). Secondary endpoints included toxicity, PFS at 24 weeks, PSA response, response of measureable disease and overall survival. 35 pts were needed in a Simon's two stage optimal design with a power of 90% and a significance level of 5% in order to test PFS rate at 12 weeks of £10% vs ?30%. Results: 35 evaluable pts were enrolled at 15 Swiss centers between 7/08 and 9/09. Median follow up was 14.8 months. Confirmed PFS at 12 weeks was 34% (95%CI 19-52%), PFS at 24 weeks was 20% and overall survival was 12.0 months (95%CI 7.1 -15.6). 20% (7/35) had a confirmed decline in PSA ? 50% and 31% (11/35) had a confirmed PSA decline ? 30%. Of pts with measurable disease (n=24) PR, SD and PD at week 12 was 4%, 54% and 25%, respectively (17% not evaluable). 3/9 (33%) pts with PDduring last doc ttr before inclusion reached the primary endpoint compared to 7/18 (39%) with PR or SD to last doc. 54% of evaluable pts experienced grade 3 and 6% grade 4 toxicity. Discussion: The result of the primary endpoint was promising in this first trial to test cet in combination with doc in pts with docetaxel-refractory mCRPC. Because this goal was achieved in such a highly pretreated pts population it appears that inhibition of the EGFR pathway may play a more important and persistent role in the treatment of prostate cancer than perceived so far. Further research is therefore warranted. Disclosure: R. Cathomas: - Membership on advisory board for sanofi aventis (suisse) and Merck. S.

There and back again? Combining habitat suitability modelling and connectivity analyses to assess a potential return of the otter to Switzerland

After a steady decline in the early 20th century, several terrestrial carnivore species have recently recovered in Western Europe, either through reintroductions or natural recolonization. Because of the large space requirements of these species and potential conflicts with human activities, ensuring their recovery requires the implementation of conservation and management measures that address the environmental, landscape and social dimensions of the problem. Few examples exist of such integrated management. Taking the case of the otter (Lutra lutra) in Switzerland, we propose a multi-step approach that allows to (1) identify areas with potentially suitable habitat, (2) evaluate their connectivity, (3) verify the potentiality of the species recolonization from populations in neighbouring countries. We showed that even though suitable habitat is available for the species and the level of structural connectivity within Switzerland is satisfactory, the level of connectivity with neighbouring populations is crucial to prioritize strategies that favour the species recovery in the field. This research is the first example integrating habitat suitability and connectivity assessment at different scales with other factors in a multi-step assessment for species recovery.

Sham nepotism as a result of intrinsic differences in brood viability in ants.

In animal societies, cooperation for the common wealth and latent conflicts due to the selfish interests of individuals are in delicate balance. In many ant species, colonies contain multiple breeders and workers interact with nestmates of varying degrees of relatedness. Therefore, workers could increase their inclusive fitness by preferentially caring for their closest relatives, yet evidence for nepotism in insect societies remains scarce and controversial. We experimentally demonstrate that workers of the ant Formica exsecta do not discriminate between highly related and unrelated brood, but that brood viability differs between queens. We further show that differences in brood viability are sufficient to explain a relatedness pattern that has previously been interpreted as evidence for nepotism. Hence, our findings support the view that nepotism remains elusive in social insects and emphasize the need for further controlled experiments.

Thomas Mann's Death in Venice or Plutarch's way towards Eros

In Death in Venice Thomas Mann refers explicitly to Plato's Symposium and Phaedrus in order to explain the relationship between Gustav von Aschenbach and Tadzio but he hides that his novel also depends on Plutarch's Eroticus. Why? The aim of this article is precisely to reveal the different reasons for such an attitude. Indeed, Plutarch speaks highly of conjugal love in his Eroticus and this way is not followed by Mann in Death in Venice but, at the same, the German writer finds in this Plutarch's philosophical dialogue all the necessary elements to build his story of masculine love and decides not to manage without it.

Some critical reflections on Michel Foucault's reading of Plutarch's Eroticus (Amatorius)

This aim of this article is to reflect on Michel Foucault's reading of Plutarch's Eroticus in his Histoire de la sexualité, putting emphasis on the fact that, against what it is affirmed by the French thinker, the real debate is not, in the author's opinion, about true pleasure, that obtained by the erastés from his erómenos or that obtained by husbands from their wives, but the need to assign also love and friendship (éros kaì philia) to the conjugal love.
