Primary Health Care from the perception of women living in a rural area

AbstractOBJECTIVEUnderstanding the perception of women living in a rural area about the actions and services of Primary Health Care (PHC) in a municipality of southern Brazil, which is the only one regarded as predominantly rural.METHODA descriptive study of qualitative approach, carried out with women who lived in the countryside and required health services in the 15 days prior to collection.RESULTSThe results registered low fidelity to PHC attributes, focusing its functional axis on sickness, transforming the unit into small points of emergency care and a bureaucratic place where patients are referred to other types of services. The quality of service offered is compromised to offering quick, fragmented and unequal treatment in the rural context.CONCLUSIONThe findings of this study highlight the need for greater efforts in order to adequate the new care model in the development of appropriate actions as designated by PHC in the rural context studied.

Activities of tabanids (Diptera, Tabanidae) attacking domestic duck-Cairina moschata (Linnaeus) (Aves, Anatidae), introduced in a forest area in the Central Amazon, Manaus, Brazil

Presented here are the feeding habits, attack behavior, daily and annual activity of adult of Phorcotabanus cinereus (Wiedeman, 1821), Chrysops laetus (Fabricius, 1805) and Phaeotabanus cajennensis (Fabricius, 1787), while biting a domestic duck, Cairina moschata (Linnaeus, 1758). The last two species were recorded for the first time attacking birds. This study comprehended monthly observations of two consecutive days from April/97 to March/98 between 5:30 a.m. and 6:30 p.m. at the Army Instructional Base ((BI-2/CIGS) near Manaus. Annual occurrence of P. cinereus was from July to September, with a daily occurrence between 9:00 a.m. and 5:00 p.m. and highest activity at 12:00 a.m. and 2:00 p.m. C. laetus ocurred from June to October; with a daily occurrence between 8:00 a.m. and 3 p.m. and highest activity at 11:00 and 12:00 a.m. Occurrence of P. cajennensis with one specimen only, was in July between 10:00 and 11:00 a.m.

Nest distribution and nesting habits of Xylocopa ordinaria Smith (Hymenoptera, Apidae) in a restinga area in the northern Rio de Janeiro State, Brazil

This paper aims to study the distribution of natural nests of Xylocopa ordinaria and characterize its nesting habits in the restinga of Grussai/Iquipari (RJ), supporting future studies on the pollinators management in the northern Rio de Janeiro state. The data obtained from Aug/2003 to Dec/2004, in an area of 11.6ha, were related to the nest distribution, substrate identification and dimensions, emergence, sex ratio, nest structure (n= 23 nests) and pollen content analysis of provisioning masses and feces. X. ordinaria nests were abundant and presented a clustered distribution. These bees do not present taxonomical affinity for nesting substrates, but preferences for wood availability and characteristics, being Pera glabrata the main substrate. X. ordinaria is a multivoltine species that tolerates co-specifics in their nests. These bees were generalist on their nectar and pollen consumption, but presented floral constancy while provisioning brood cells. These behaviors, activity along the year, flights throughout the day, and legitimate visits to flowers indicate the importance of X. ordinaria on the pollination of plants in the restinga.

Late Proterozoic thrust tectonics, high-pressure metamorphism and Uranium mineralization in the domes area, Lufilian arc, northwestern Zambia

The following main lithostratigraphic units have been distinguished in the Domes Area. The Kibaran basement complex composed of gneisses, migmatites with amphibolite bands and metagranites is exposed in dome structures; metamorphic features of Kibaran age have been almost completely obliterated by extensive Lufilian reactivation. The post-Kibaran cover sequence is subdivided into the Lower Roan Group consisting of well-preserved quartzites with high Mg content, talc-bearing, extremely foliated schists intercalated with pseudo-conglomerates of tectonic origin and the Upper Roan Group including dolomitic marbles with rare stromatolites, metapelites and a sequence of detrital metasediments, with local volcano-sedimentary components and interlayered banded ironstones. The sediments of the Lower Roan Group are interpreted as continental to lagoonal-evaporitic deposits partly converted into the talc-kyanite + garnet assemblage characteristic of ``white schists''. The dolomites and metapelites of the Upper Roan Group are attributed to a carbonate platform sequence progressively subsiding under terrigenous deposits, whilst the detrital metasediments and BIF may be interpreted as a basinal sequence, probably deposited on oceanic crust grading laterally into marbles. Metagabbros and metabasalts are considered as remnants of an ocean-floor-type crustal unit probably related to small basins. Alkaline stocks of Silurian age intruded the post-Kibaran cover. Significant ancestral tectonic discontinuities promoted the development of a nappe pile that underwent high-pressure metamorphism during the Lufilian orogeny and all lithostratigraphic units. Rb-Sr and K-Ar and U-Pb data indicate an age of 700 Ma for the highest grade metamorphism and 500 Ma for blocking of the K-Ar and Rb-Sr system in micas, corresponding to the time when the temperature dropped below 350-degrees-400-degrees-C and to an age of about 400 Ma for the emplacement of hypabyssal syenitic bodies. A first phase of crustal shortening by decoupling of basement and cover slices along shallow shear zones has been recognized. Fluid-rich tectonic slabs of cover sediments were thus able to transport fluids into the anhydrous metamorphic basement or mafic units. During the subsequent metamorphic re-equilibration stage of high pressure, pre-existing thrusts horizons were converted into recrystallized mylonites. Due to uplift, rocks were re-equilibrated into assemblages compatible with lower pressures and slightly lower temperatures. This stage occurs under a decompressional (nearly adiabatic) regime, with P(fluid) almost-equal-to P(lithostatic). It is accompanied by metasomatic development of minerals, activated by injection of hot fluids. New or reactivated shear zones and mylonitic belts were the preferred conduits of fluids. The most evident regional-scale effect of these processes is the intense metasomatic scapolitization of formerly plagioclase-rich lithologies. Uraninite mineralization can probably be assigned to the beginning of the decompressional stage. A third regional deformation phase characterized by open folds and local foliation is not accompanied by significant growth of new minerals. However, pitchblende mineralization can be ascribed to this phase as late-stage, short-range remobilization of previously existing deposits. Finally, shallow alkaline massifs were emplaced when the level of the Domes Area now exposed was already subjected to exchange with meteoric circuits, activated by residual geothermal gradients generally related to intrusions or rifting. Most of the superficial U-showings with U-oxidation products were probably generated during this relatively recent phase.

Monetary policy in the Euro area: Lessons from 5 years of ECB and implications for Turkey

We examine monetary policy in the Euro area from both theoretical and empirical perspectives. We discuss what theory tells us the strategy of Central banks should be and contrasts it with the one employed by the ECB. We review accomplishments (and failures) of monetary policy in the Euro area and suggest changes that would increase the correlation between words and actions; streamline the understanding that markets have of the policy process; and anchor expectation formation more strongly. We examine the transmission of monetary policy shocks in the Euro area and in some potential member countries and try to infer the likely effects occurring when Turkey joins the EU first and the Euro area later. Much of the analysis here warns against having too high expectations of the economic gains that membership to the EU and Euro club will produce.

New evidence on inflation persistence and price stickiness in the Euro area: Implications for macro modelling

This paper evaluates new evidence on price setting practices and inflation persistence in the euro area with respect to its implications for macro modelling. It argues that several of the most commonly used assumptions in micro-founded macro models are seriously challenged by the new findings.

The adverse effects of environmental policy in green markets

We model green markets in which purchasers, either firms orconsumers, have higher willingness-to-pay for lesspolluting goods. The effectiveness of pollution reductionpolicies is examined in a duopoly setting. We show thatduopolists' strategic behaviour may increase pollutionlevels. Maximum emission standards, commonly used in greenmarkets, improve the environmental features of products.Nonetheless, overall pollution levels will rise becausegovernment regulation also affects market shares and bootsfirms' sales. Consequently, social welfare may be reduced.We also explore the effects of technological subsidies andproduct charges, including differentiation of charges.

Bat flies (Diptera, Streblidae and Nycteribiidae) in a Cerrado area of Goiás State, Brazil

A survey of bat flies was carried out in the Brazilian savanna (Cerrado) in the Goiás state, Brazil. We collected 227 specimens of seventeen species belonging to nine genera of Streblidae and seven specimens of four species of Basilia Miranda-Ribeiro, 1903 (Nycteribiidae). Except for Paratrichobius longicrus (Miranda-Ribeiro, 1907) (Streblidae), all species are new recorded in Goiás.

Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) (Diptera, Psychodidae, Phlebotominae) in a sympatric area: seasonal and nocturnal hourly rhythm in black and white modified Shannon traps

Captures with black and white Shannon traps were undertaken to identify aspects of the behavior of the two cryptic and sympatric species implicated as vectors of cutaneous leishmaniasis, Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926). The traps were installed side by side, monthly, from July 2001 to June 2002, from 18 to 07 hours, in a peridomicile of Iporanga municipality, state of São Paulo, Brazil. A total of 2,142 specimens were captured, Ny. intermedia (47.4%) and Ny. neivai (50.5%). The white trap was more attractive to both sexes of both species. Males of Ny. neivai predominated (70%) over those of Ny. intermedia on the two traps; on the black trap, the females of Ny. intermedia predominated (63.3%) over those of Ny. neivai (36.7%). Seventy percent of the specimens of both species were captured between 18 and 24 h. Females of Ny. intermedia presented the highest peak at 19-20 h, and those of Ny. neivai at 20-21 h. The highest hourly average for females of Ny. intermedia on the black trap occurred in the winter and that for males in the summer. For Ny. neivai, both sexes predominated in the summer. The two species probably transmit the cutaneous leishmaniasis in the area due to their great predominance.

Reinitialization of evolutionary clocks during sublethal environmental stress in some invertebrates

This paper describes the influence of high environmental stress on evolutionary trends in some selected Mesozoic ammonite lineages and some protists. During extinction periods, many ammonoids are affected by drastic simplifications of their shell geometry, ornamentation and suture line. We observe that relatively tightly coiled ammonites can give rise to highly evolute forms or uncoiled heteromorphs with simple ornamentation and almost ceratitic suture line-a phenomenon called "proteromorphosis". Such simplifications often correspond to a reappearance of ancestral geometries (primitive ornamentation, evolute coiling or uncoiling) which suggest that the evolutionary clock of these organisms can be reinitialized by extreme, sublethal, environmental stress such as giant volcanism (including its consequences on diverse pollutions and on climatic changes) and major regressive events.

Two myrmecophilous scale insects, Cryptostigma urichi (Cockerell) (Hemiptera, Coccidae) and Farinococcus multispinosus Morrison (Hemiptera, Pseudococcidae), cohabiting inside branches of Anadenanthera falcata (Benth.) Speg. (Fabales, Fabaceae) in the Cerrado area of São Paulo State, Brazil

The soft scale Cryptostigma urichi (Cockerell, 1894) and the mealybug Farinococcus multispinosus Morrison, 1922 are reported cohabiting inside branches of Anadenanthera falcata (Benth.) Speg. (Angico-preto), both tended by the ant Azteca oecocordia Longino, 2007 (Hymenoptera, Formicidae). This interaction was observed in the Cerrado region sensu stricto, at the Federal University of São Carlos, UFSCar, Brazil. A. oecocordia is recorded for the first time in Brazil.

Patterns of convergence and divergence in the euro area

We study the extent of macroeconomic convergence/divergence among euro area countries. Our analysis focuses on four variables (unemployment, inflation, relative prices and the current account), and seeks to uncover the role played by monetary union as a convergence factor by using non-euro developed economies and the pre-EMU period as control samples.

Genetic and maternal contributions to offspring viability under different environmental conditions in various salmonids

Summary : Due to anthropogenic impacts and natural fluctuations, fish usually have to cope with constantly changing and often hostile environments. Whereas adult fish have various possibilities to counteract unfavourable environmental conditions, embryos have much fewer options. Besides by their developing immune system, they are protected by the egg envelopes and several immune substances provided by their mothers. In addition to this, they may also adjust their hatching timing in reaction to various risks. However, individuals may vary in their defensive potential. This variation may be either based on their genetics and/or on differential maternal investments and may be dependent on the experienced stress. Nevertheless, in fish, the impact of such parental contributions on embryo and/or juvenile viability is still poorly investigated. The main objective of this thesis was to investigate the importance of paternal (i.e. genetic) and maternal (i.e. genetic + egg investment) contributions to offspring viability under different environmental conditions and at different life stages. In order to investigate this, we used gametes of various salmonids for in vitro fertilisation experiments based on full-factorial breeding designs. The individual studies are summarised in the following chapters: In the first chapter, we tested the effectiveness of the embryonic immune system in Lake whitefish (Coregonus palaea). Namely, we investigated paternal and maternal contributions to the embryos' tolerance to different kinds of pathogen exposure. Additionally, we tested whether an early sub-léthal exposure has a positive or a negative effect on an embryo's susceptibility to later pathogen exposures with the same pathogen. We found that pre-challenged embryos were more susceptible to future challenges. Moreover, pathogen susceptibility was dependent on maternal investments and/or the embryos' own genetics, depending on the challenge level. Chapter 2 summarises a similar study with brown trout (Salmo trutta). In addition to the previously described investigations, we analysed if genetic effects on offspring viability are mediated either by parental MHC genotypes or relatedness based on neutral microsatellite markers, and we tested if males signal their genetic quality either by their body size or their melanin-based skin colouration. We found that embryo survival was lower at higher stress levels and dependent on the embryos' genetics. Addirionally, parents with similar and/or, very common MHC genotypes had higher offspring viabilities. Finally, darker males produced more viable offspring. In the first two chapters we investigated the embryos' defensive potential based on their immune system, i.e. their pathogen tolerance. In chapter 3 we investigate whether hatching timing of Lake whitefìsh (C. palaea) is dependent on parental contributions and/or on pathogen pressure, and whether there are parental-environmental interactions. We found that whitefish embryos hatch earlier under increasing pathogen pressure. Moreover, hatching timing was affected by embryo genetics and/or maternally provided resources, but the magnitude of the effect was dependent on the pathogen. pressure. We also found a significant paternal-environmental interaction, indicating that the hatching efficiency of a certain sib group is dependent on the pathogen environment. Chapter 4 describes an analogous study with brown trout (S. trutta), with similar findings. In the former chapters, we only looked at offspring performance during the embryonic period, and only under semi-natural conditions. In chapter 5 we now test the performance and viability of embryonic and juvenile brown trout (S. trutta) under natural conditions. To measure embryo viability, we put them in brood boxes, buried them in the gravel of a natural river, and analysed survival after several months. To investigate juvenile survival and performance, wé reared embryos under different stress levels in the laboratory and subsequently released the resulting hatchlings in to a closed river section. Juvenile size and survival was then determined one year later. Additionally, we investigated if sires differ in their genetic quality, determined by embryo and juvenile survival as well as juvenile size, and if they signal their quality by either body size or melanin-based body darkness. We found hat juvenile size was dependent on genetic effects and on maternal investment, whereas this was neither the case for embryo nor for juvenile survival. Additionally, we found that offspring of darker males grew larger, and larger juveniles had also an increased survival. Finally, we found acarry-over effect of the early non-lethal challenge: exposing embryos to higher stress levels resulted in smaller juveniles. To evaluate the long-term performance of differently treated groups, mark-recapture studies are inevitable. For this purpose, effective mass-marking techniques are essential. In chapter 6 we tested the suitability of the fluorescent pigment spray marking method for the mass marking of European graylings (Thymallus thymallus), with very promising results. Our in vitro fertilisation studies on whitefish may reveal new insights on potential genetic benefits of mate choice, but the mating system of whitefish under natural conditions is still poorly investigated. In order to study this, we installed underwater cameras at the spawning place of a Coregonus suidteri population, recorded the whole mating period and subsequently analysed the recordings. Confirmations of previous findings as well as exciting new observations are listed and discussed in chapter 7. Dus aux impacts anthropogéniques et aux fluctuations naturelles, les poissons doivent faire face à des environnements en perpétuel changement. Ces changements font que les poissons doivent s'adapter à de nouvelles situations, souvent hostiles pour eux. Les adultes ont différentes possibilités d'échapper à un environnement peu favorable, ce n'est par contre pas le cas des embryons. Les embryons sont protégés d'une part par leur système immunitaire en développement, d'autre part, par la coquille de l'eeuf et différentes substances immunitaires fournies par leur mère. De plus, ils sont capables d'influencer leur propre date d'éclosion en réponse à différents facteurs de stress. Malgré tout, les individus varient dans leur capacité à se défendre. Cette variation peut être basé sur des facteurs génétiques et/ou sur des facteurs maternels, et est dépendante du stress subi. Néanmoins, chez les poissons, l'impact de telles contributions parentales sur la survie d'embryons et/ou juvéniles est peu étudié. L'objectif principal de cette thèse a été d'approfondir les connaissances sur l'importance de la contribution paternelle (c.a.d. génétique) et maternelle (c.a.d. génétique + investissement dans l'oeuf) sur la survie des jeunes dans différentes conditions expérimentales et stades de vie. Pour faire ces analyses, nous avons utilisé des gamètes de divers salmonidés issus de croisements 'full-factorial'. Les différentes expériences sont résumées dans les chapitres suivants: Dans le premier chapitre, nous avons testé l'efficacité du système immunitaire des embryons chez les corégones (Coregonus palea). Plus précisément nous avons étudié la contribution paternelle et maternelle à la tolérance des embryons à différents niveaux de stress pathogène. Nous avons aussi testé, si une première exposition non létale à un pathogène avait un effet positif ou négatif sur la susceptibilité d'un embryon a une deuxième exposition au même pathogène. Nous avons trouvé que des embryons qui avaient été exposés une première fois étaient plus sensibles au pathogène par la suite. Mais aussi que la sensibilité au pathogène était dépendante de l'investissement de la mère et/ou des gènes de l'embryon, dépendamment du niveau de stress. Le deuxième chapitre résume une étude similaire avec des truites (Salmo truffa). Nous avons examiné, si la survie des jeunes variait sous différentes intensités de stress, et si la variance observée était due aux gènes des parents. Nous avons aussi analysé si les effets génétiques sur la survie des juvéniles étaient dus au MHC (Major Histocompatibility Complex) ou au degré de parenté des parents. De plus, nous avons analysé si les mâles signalaient leur qualité génétique par la taille du corps ou par leur coloration noire, due à la mélanine. On a trouvé que la survie des embryons était plus basse quand le niveau de stress était plus haut mais que la variation restait dépendante de la génétique des embryons. De plus, les parents avec des MHC similaires et/ou communs avaient des embryons avec une meilleure survie. Par contre, des parents avec un degré de parenté plus haut produisent des embryons avec une survie plus mauvaise. Finalement nous avons montré que les mâles plus foncés ont des embryons qui survivent mieux, mais que la taille des mâles n'a pas d'influence sur la survie de ces mêmes embryons. Dans les deux premiers chapitres, nous avons étudié le potentiel de défense des embryons basé sur leur système immunitaire, c.a.d. leur tolérance aux pathogènes. Dans le troisième chapitre, nous nous intéressons à la date d'éclosion des corégones (C. palea), pour voir si elle est influencée par les parents ou par la pression des pathogènes, et si il y a une interaction entre ces deux facteurs. Nous avons trouvé que les jeunes naissent plus rapidement lorsque la pression en pathogènes augmente. La date d'éclosion est influencée par la génétique des embryons et/ou l'investissement des parents, mais c'est la magnitude des effets qui est dépendante de la pression du pathogène. Nous avons aussi trouvé une interaction entre l'effet paternel et l'environnement, ce qui indique que la rapidité d'éclosion de certains croisements est dépendante des pathogènes dans l'environnement. Le chapitre 4 décrit une étude analogue avec de truites (S. truffa), avec des résultats sitzimilaires. Dans les précédents chapitres nous nous sommes uniquement concentrés sur les performances des jeunes durant leur stade embryonnaire, et seulement dans des conditions semi naturelles. Dans le chapitre 5 nous testons la performance et la viabilité des embryons et de juvéniles de truites (S. truffa) dans des conditions naturelles. Nous avons trouvé que la taille des juvéniles était dépendante d'effets génétiques et de l'investissement maternel, mais ceci n'était ni les cas pour les survie des embryons et des juvéniles. De plus, nous avons trouvé que les jeunes des mâles plus foncés devenaient plus grands et que les grands ont un meilleur taux de survie. Finalement nous avons trouvé un 'carry-over effect' d'une première exposition non létale à un pathogène: exposer des embryons à des plus hauts niveaux de stress donnait des juvéniles plus petits. Pour évaluer la performance à long terme de groupes traités dé manières différentes, une méthode de marquage-recapture est inévitable. Pour cette raison, des techniques de marquage en masse sont nécessaires. Dans le chapitre 6, nous avons testé l'efficacité de la technique `fluorescent pigment spray marking' pour le marquage en masse de l'Ombre commun (Thymallus thymallus), avec des résultats très prometteurs. Les études de fertilisations in vitro avec les corégones nous donnent une idée du potentiel bénéfice génétique que représente la sélection d'un bon partenaire, même si le système d'accouplement des corégones en milieu naturel reste peu connu. Pour combler cette lacune, nous avons installé des caméras sous-marines autour de la frayère d'une population de corégones (C. suidteri), nous avons enregistré toute la période de reproduction et nous avons analysé les données par la suite. Ainsi, nous avons été capables de confirmer bien des résultats trouvés précédemment, mais aussi de faire de nouvelles observations. Ces résultats sont reportés dans le septième chapitre, où elles sont comparées avec des observations antérieures.

Localization and characterization of an active fault in an urbanized area in central Guatemala by means of geoelectrical imaging

The Polochic and Motagua faults define the active plate boundary between the North American and Caribbean plates in central Guatemala. A splay of the Polochic Fault traverses the rapidly growing city of San Miguel Uspantan that is periodically affected by destructive earthquakes. This fault splay was located using a 2D electrical resistivity tomography (ERT) survey that also characterized the fault damage zone and evaluated the thickness and nature of recent deposits upon which most of the city is built. ERT images show the fault as a similar to 50 m wide, near-vertical low-resistivity anomaly, bounded within a few meters by high resistivity anomalies. Forward modeling reproduces the key aspects of the observed electrical resistivity data with remarkable fidelity thus defining the overall location, geometry, and internal structure of the fault zone as well as the affected lithologies. Our results indicate that the city is constructed on a similar to 20 m thick surficial layer consisting of poorly consolidated, highly porous, water-logged pumice. This soft layer is likely to amplify seismic waves and to liquefy upon moderate to strong ground shaking. The electrical conductivity as well as the major element chemistry of the groundwater provides evidence to suggest that the local aquifer might, at least in part, be fed by water rising along the fault. Therefore, the potential threat posed by this fault splay may not be limited to its seismic activity per se, but could be compounded its potential propensity to enhance seismic site effects by injecting water into the soft surficial sediments. The results of this study provide the basis for a rigorous analysis of seismic hazard and sustainable development of San Miguel Uspantan and illustrate the potential of ERT surveying for paleoseismic studies.

Plant species richness and environmental heterogeneity in a mountain landscape: effects of variability and spatial configuration

The loss of biodiversity has become a matter of urgent concern and a better understanding of local drivers is crucial for conservation. Although environmental heterogeneity is recognized as an important determinant of biodiversity, this has rarely been tested using field data at management scale. We propose and provide evidence for the simple hypothesis that local species diversity is related to spatial environmental heterogeneity. Species partition the environment into habitats. Biodiversity is therefore expected to be influenced by two aspects of spatial heterogeneity: 1) the variability of environmental conditions, which will affect the number of types of habitat, and 2) the spatial configuration of habitats, which will affect the rates of ecological processes, such as dispersal or competition. Earlier, simulation experiments predicted that both aspects of heterogeneity will influence plant species richness at a particular site. For the first time, these predictions were tested for plant communities using field data, which we collected in a wooded pasture in the Swiss Jura mountains using a four-level hierarchical sampling design. Richness generally increased with increasing environmental variability and "roughness" (i.e. decreasing spatial aggregation). Effects occurred at all scales, but the nature of the effect changed with scale, suggesting a change in the underlying mechanisms, which will need to be taken into account if scaling up to larger landscapes. Although we found significant effects of environmental heterogeneity, other factors such as history could also be important determinants. If a relationship between environmental heterogeneity and species richness can be shown to be general, recently available high-resolution environmental data can be used to complement the assessment of patterns of local richness and improve the prediction of the effects of land use change based on mean site conditions or land use history.
