Helminofauna da sarda (Scomber scombrus L. ) peixe da Costa Continental Portuguesa

Dos primerios 80 espécimens da sarda examinados (de janeiro a maio de 1982), apenas seis (7,5%) estavam livres de helmintos, apresentando os demais as espécies de parasitos seguintes, por ordem de freqüência dentro de cada grupo taxonômico: Kuhnia scombri (Kuhn, 1829) e Grubea cochlear (Diesing, 1858) (classe Monogenea); Lecithocladium excisum (Rudolph, 1819) e Opechona basillaris (Molin, 1859)(classe Digenea); pelrocercoides de Lacistrorhynchus tenuis (Beneden, 1858) de Scolex pleuronectis (Muller, 1788) e de Echeneibothrium sp. (classe Cestoda); Rhadinorhynchus tenuicornis (Linton, 1891) (filo Acanthocephala); formas dos tipos larvares Anisakis e Contracaecum e ainda, larvas de Goezia sp. (classe Nematoda). São referidas, pela primeira vez, neste hospedeiro, formas larvares do cestóide Echeneibothrium sp. e do nematóide Goezia sp.

A genitália externa dos machos de sete espécies de Triatoma Laporte, 1832 da região Neártica (Hemiptera, Reduviidae, Triatominae)

Sete espécies da região neártica: Triatoma barberi Usinger, 1939; T. rubida (Uhler, 1894); T. gertaeckeri (Stal, 1859); T. lecticularia (Stal, 1859); T. protracta (Uhler, 1894); T. recurva (Stal, 1868) e T. sanguisuga (Leconte, 1855) foram analisadas comparativamente, tendo como enfoque as estruturas da genitália do macho: falosoma (Ph), suporte do falosoma (SPh), processo do endosoma (PrEn), vesica (V) e aparelho articular (Apb). As estruturas fálicas se mostraram capazes de serem usadas como critério morfológico suplementar aos padrões atualmente usados, em taxonomia. Estas espécies silvestres são encontradas nos Estados Unidos e México, naturalmente infectadas pelo T. cruzi; algumas vivem no perdomicílio e outras eventualmente no domicílio, sem contudo colonizá-lo.

Public Governance, Health and Foreign Direct Investment in Sub-Saharan Africa

In this paper we diverge from the existing empirical literature on FDI determinants in two ways. First, we decompose the sources of the foreign direct investment (FDI) gap between Sub-Saharan Africa (SSA) and other developing regions. Once market size has been accounted for, we nd that SSA's FDI de cit is mostly explained by insufficient provision of public goods: low human capital accumulation, especially health, in SSA explains 100-140% of the inter-regional FDI gaps. Second, we estimate the indirect effect of infectious diseases on FDI through their direct impact on health. We find that a 1% point rise in HIV prevalence in the adult population is associated with a decrease in net FDI inflows of 3.5%, while a country in which 100% of the population is at risk of contracting deadly malaria receives about 16% less FDI than a similar country located in a malaria-free region.

Short-Run Strategies For Attracting Foreign Direct Investment

This paper empirically investigates the effectiveness and feasibility of two FDI policies, fiscal incentives and deregulation, aimed at improving the attractiveness of a country in the short run. Using disaggregated data on sales by US MNEs’ foreign affiliates in 43 developed and developing countries over the 1982-1994 period, results show that the provision of fiscal incentives or the deregulation of the labour market would exert a positive impact on total FDI. Given the drawbacks frequently associated with the use of incentive packages, economy-wide policies which ease firing procedures and reduce severance payments would certainly be the best policy option. This paper also highlights the different aggregation and omitted variable biases that have affected results of previous studies and provides some support to recent theoretical models of FDI by showing that third country effects and spatial interdependence influence respectively the location of export-platform FDI and vertical FDI.

Who Ultimately Bears the Burden of Greater Non-Wage Labour costs?

We investigate the effect of a rise in non-wage labour costs (NWLC) on real anufacturing labour costs in OECD countries, taking into account the degree of coordination in the wage bargaining process. We find that, in countries in which wage bargaining is not highly coordinated, 55% of an increase in NWLC appears to be shifted to workers in the long run, whereas in countries operating under a highly coordinated bargaining regime, full shifting occurs. Overall, our results suggest that high NWLC can be associated with a high equilibrium unemployment rate, but only in those OECD countries that do not have highly coordinated wage bargaining.

Does Public Governance Always Matter? How Experience of Poor Institutional Quality Influences FDI to the South

This paper investigates whether the higher prevalence of South multinational enterprises (MNEs) in risky developing countries may be explained by the experience that they have acquired of poor institutional quality at home. We confirm the intuition provided by our analytical model by empirically showing that the positive impact of good public governance on foreign direct investment (FDI) in a given host country is moderated significantly, and even in some cases eliminated, when MNEs have been faced with poor institutional quality at home.

Market Familiarity and the Location of South and North MNEs

We use a systematic empirical analysis of the determinants of South-South (SS) and North-South (NS) foreign direct investment (FDI) as a canvas to explore how multinational enterprises’ (MNEs) location decisions are shaped by better acquaintance with a foreign market resulting from bilateral ties, experience of international expansion, and knowledge of how to deal with poor governance. We find that these various aspects of market familiarity, which can interact together, are important to explain and differentiate the location behaviours of South MNEs (S-MNEs) and North MNEs (N-MNEs) in developing countries.

Estudo comparado do ciclo evolutivo de triatomíneos a duas temperaturas

We studied the life cicle of several triatominae species: Dipetalogaster maximus (Uhler, 1894); Panstrongylus herreri Wygodzinsky, 1948; Panstrongylus megistus (Burmeister, 1835); Rhodnius ecuadoriensis Lent & Leon, 1958; Rhodnius nasutus Stal, 1859; Rhodnius neglectus Lent, 1954; Rhodnius pictipes Stal, 1872; Rhodnius prolixus Stal, 1859; Rhodnius robustus Larrousse, 1927; Triatoma brasiliensis Neiva, 1911; Triatoma infestans (Klug, 1834); Triatoma maculata (Erichson, 1848); Triatoma matogrossensis Leite & Barbosa, 1953; Triatoma platensis Neiva, 1913; Triatoma protracta (Uhler, 1894); Triatoma sordida (Stal, 1859); Triatoma tibiamaculata (Pinto, 1926) e Triatoma vitticeps (Stal, 1859) (Hemiptera, Reduviidae). The main purpose of the study was to obtain information to improve control measures specially in those peridomiciliar species. The experiments were performed in two climatized chambers, both with an humidity of 70 ± 5% and photoperiod of 12 hours. One was maintained at 25 ± 0,5ºC and the other at 30 ± 1ºC.

Institutional Quality and FDI to the South An Analytical Approach

We ask whether MNEs’ experience of institutional quality and political risk within their “home” business environments influences their decisions to enter a given country. We set out an explicit theoretical model that allows for the possibility that firms from South source countries may, by virtue of their experience with poor institutional quality, derive a competitive advantage over firms from North countries with respect to investing in destinations in the South. We show that the experience gained by such MNEs of poorer institutional environments may result in their being more prepared to invest in other countries with correspondingly weak institutions.

The Known Unknowns of Governance.

Empirical researchers interested in how governance shapes various aspects of economic development frequently use the Worldwide Governance indicators (WGI). These variables come in the form of an estimate along with a standard error reflecting the uncertainty of this estimate. Existing empirical work simply uses the estimates as an explanatory variable and discards the information provided by the standard errors. In this paper, we argue that the appropriate practice should be to take into account the uncertainty around the WGI estimates through the use of multiple imputation. We investigate the importance of our proposed approach by revisiting in three applications the results of recently published studies. These applications cover the impact of governance on (i) capital flows; (ii) international trade; (iii) income levels around the world. We generally find that the estimated effects of governance are highly sensitive to the use of multiple imputation. We also show that model misspecification is a concern for the results of our reference studies. We conclude that the effects of governance are hard to establish once we take into account uncertainty around both the WGI estimates and the correct model specification.

Itinéraires : les guides de voyage en Suisse de la fin du XVIIIe siècle à 1914 : contribution à une histoire culturelle du tourisme

Menée dans une approche d'histoire culturelle, cette thèse de doctorat prend pour objet un corpus de guides de voyage en Suisse entre la fin du XVIIIe et le début du XXe siècle. Centrée sur les guides, ces livres qui entretiennent plus que d'autres des liens étroits avec le monde physique, elle a deux grands axes. Le premier est une lecture interdisciplinaire des guides de voyage, qui mêle littérature, bibliographie matérielle, histoire et histoire de l'art. Elle a cherché à comprendre les raisons et logiques du genre, en s'attachant particulièrement à ses fonctions et à ses formes (tant structurelles que textuelles et iconographiques). Cette partie de l'étude est importante, car elle n'a encore jamais été menée. Elle s'articule en deux volets : un volet théorique qui s'intéresse à l'histoire et à la forme des guides de voyage ; et une étude de cas qui s'attache à la lecture plus rapprochée de 6 guides : ceux de Thomas Martyr (1788, 1790 & 1794), Heinrich August Ottokar Reichard (1793 & 1802) et Johann Gottfried Ebel (1793, 1805, 1810-11 & 1817-18) pour la fin du XVIIIe siècle et le tournant du XIXe, et ceux de John Murray (1838 & 1886), Adolphe Joanne (1841, 1865, 1874, 1882 & 1908) et Karl Baedeker (1844, 1852, 1859, 1869, 1876, 1883, 1893, 1901 & 1913) pour le XIXe et la Belle Epoque. Le second axe de cette recherche est une réflexion sur les manières de mettre en scène l'espace dans un texte. En étudiant les itinéraires de voyage en Suisse (mais jusqu'au début du XXe siècle, « la Suisse »est pour les guides de voyage indifféremment un pays et une région supranationale : «les Alpes »), quatre types de mises en forme ont pu être identifiés : le voyage en boucle (linéaire, il part d'un point A pour y revenir), le voyage en marguerite (linéaire avec excursions), le voyage éclaté de l'ordre alphabétique, et enfin le voyage par «routes », fragments d'espace que l'on combine comme les pièces d'un puzzle, créant son chemin au fur et à mesure de sa progression. Ce faisant, on peut affirmer que les guides de voyage modernes (dont la forme se fixe dans les années 1830-1840 avec les premiers Murray, Baedeker et Joanne) se sont construits -malgré tout ce que l'on a pu dire sur la normativité prescriptive du tourisme -autour d'une liberté de plus en plus grande accordée aux voyageurs. Chacune de ces formes et chacun de ces types ayant une histoire et des conditions de possibilités, c'est en s'appuyant sur celles-ci que l'on peut mieux comprendre non seulement l'évolution du voyage et de ses pratiques, mais aussi la constitution de la forme littéraire qui l'a accompagné et permis. Ce faisant, des jalons pour une histoire culturelle du tourisme ont aussi été posés, histoire culturelle que j'appelle maintenant de mes voeux : il est quand même surprenant que, dans le pays de tourisme qu'est la Suisse, quand on s'est jusqu'à présent attaché à l'histoire du tourisme, on n'ait parlé qu'économie, société, infrastructures, loisirs ou santé, voire, plus récemment, écologie et bien-être. Redonner son creuset culturel à ce phénomène, c'est aussi retrouver une part du nôtre, car ces mémoires s'entremêlent indissociablement.

Durcissement des lois sociales et santé des migrants forcés: trois ans après (a Loi sur l'asile (LAsi) [Social policy hardening and forced immigrant's health: 3 years after the Asylum Law (LAsi)'s introduction].

In the canton de Vaud, General Practioners (GPs) caring for asylum seekers under the "aide d'urgence" regime can ask for an adaptation of their housing conditions, by filling out a specific form and addressing it to the medical commission responsible for advising the EVAM (the housing institution for asylum seekers) on these issues. The forms addressed to the commission are indicative of a worrisome state of health in this population, especially for mental health. More than 70% report at least one psychiatric diagnosis. Most frequent are anxiety and depressive disorders, as well as many posttraumatic stress disorders, associated with traumatic events both in the country of origin and in Switzerland. Adapting the housing conditions, based on vulnerabilities that the GP has specifically documented, may contribute to improve the health of the most vulnerable asylum seekers.

El concepto de sana laicidad de Benedicto XVI en la democracia de Tocqueville

Davant els canvis polítics de la Modernitat, l’Església catòlica ha desenvolupat una extensa doctrina en matèria política, que l’actual papa, Benet XVI, continua actualitzant i ampliant. A partir de les afirmacions del Sant Pare, existiria la possibilitat de preguntar-se fins a quin punt l’Església ha mantingut una única línia en el seu magisteri polític al llarg dels segles, i, en concret, entre la doctrina anterior i la posterior al Concili Vaticà II. Aquest treball té per objectiu, en primer lloc, aclarir la continuïtat o discontinuïtat de la doctrina de l’Església postconciliar respecte de l’anterior e il•lustrar les principals línies del magisteri político-social de Benet XVI. Així mateix, hom es podria preguntar en quina mesura la proposta de Benet XVI és realitzable en el context polític actual. Per donar resposta a aquesta segona qüestió, es recorrerà al anàlisis que Alexis de Tocqueville va fer de la democràcia americana i que és extrapolable a la resta de democràcies d’Occident. Mitjançant la contraposició de la doctrina política de Benet XVI i l’anàlisi que fa Tocqueville del paper de la religió en les democràcies, es tractarà d’esclarir fins a quin punt el magisteri de Benet XVI sobre qüestions polítiques és compatible amb la racionalitat política.
