Análisis Socioeconómico de Género - Impacto de las Políticas Agrarias en Cabo Verde

A lo largo de esta investigación se ha intentado estudiar el grado en el que el tema de género está incorporado dentro de las políticas agrarias de Cabo Verde, así como el impacto que estas generan sobre la modificación de los patrones sociales convencionales. Para ello, se ha realizado un análisis socioeconómico de género en dos comunidades del interior de la isla de Santiago, que son beneficiadas por la implementación de lo que hasta hoy es considerado como el proyecto hídrico con fines agrícolas más importante del país: la presa de Poilão. El estudio antropológico llevado a cabo en estas comunidades ha ayudado a comprender la realidad cotidiana de la población rural caboverdiana, especialmente en todo lo referente a las relaciones de poder y a las relaciones de género existentes en la actualidad.

Anomalias da hipótese de eficiência de mercado: estudo do efeito dia da semana na Bolsa de Valores de Cabo Verde

A eficiência dos mercados tem sido uma questão que tem despertado muito interesse no campo dos investimentos e da investigação financeira durante as últimas décadas, mas nos últimos anos com a intensificação dos estudos e surgimento de evidências da existência de comportamentos anómalos nas rentabilidades dos ativos financeiro, esta teoria passou a ser questionada no meio académico. A discussão do tema é ainda muito polémico, pois existem de um lado os defensores da hipótese de eficiência que defendem que as anomalias identificadas não podem ser generalizadas e não são consistentes ao longo do tempo, e de outro lado os defensores da corrente das finanças comportamentais, segundo os quais as anomalias são provocadas por padrões documentados de comportamento irracional dos investidores, sendo que estes comportamentos são inconsistentes com a teoria de eficiência dos mercados. Entre as anomalias detetadas, destacam-se as anomalias de Calendário, tais como o efeito Janeiro, efeito dia da semana, efeito feriado, entre outros; anomalias na valorização de ativos, tais como o efeito tamanho e outras anomalias de sobre reação. O efeito dia da semana é dos mais persistentes detetados em vários mercados internacionais e tendo em conta este cenário, o objetivo desta dissertação é a verificação da existência das anomalias de calendário, mais precisamente o efeito dia da semana onde se irá analisar o efeito segunda-feira, efeito sexta-feira, o efeito fim-de­ semana. Para esta verificação foram utilizadas as cotações diárias médias do Índice da Bolsa de Valores de Cabo Verde, no período de finais de 2005 a finais de 2008. A análise estatística dos resultados diários indicou que não existem evidências da existência do efeito dia da semana. ABSTRACT: The markets efficiency has been an issue of particular interest in the field of financial investigation in recent decades. However, due to the intensification of the studies and the arise of evidences about the existence of abnormal behaviours on financial assets returns, over the last years, this theory begun to be discussed in academic circles. The debate of this theme is still very controversial, because on one hand there are the defenders of the efficiency hypothesis, who defend that identified anomalies cannot be generalized and are not consistent in the long-term; on the other hand, there are the defenders of behavioral finance tendency, to whom the anomalies are caused by documented patterns about the irrational behaviour of investors. These behaviours are inconsistent with the markets efficient theory. Among the detected anomalies, we highlight the calendar anomalies, such as: the January effect, the day of week effect and holiday effect among others; anomalies over the valuation of assets, such as: the size effect and other anomalies on the reaction. The day of week effect is one of the most persistent effect detected in several international markets, and due to this scenario, the objective of this essay is the finding of calendar abnormalities, namely the day of week effect, where the Monday, the Friday and the weekend effects will be analyzed. For this checking, we used the average daily exchange rates from the prices of the Cape Verde Stock Exchange, for the period from late 2005 to late 2008. The statistical analysis of daily results indicated that there is no evidence of the existence of the day of the week effect.

Els camins "verd" i "daurat" cap a l'accés obert: arguments a favor de combinar i relacionar

Els debats recents sobre l'accés obert (OA) han tendit a tractar les revistes d'OA i l'auto-arxiu com dues rutes diferents. Alguns partidaris de l'auto-arxiu fins i tot han suggerit que per si sol aquest pot conduir a l'accés obert complet de la literatura científica mundial. En aquest article es discuteix que, de fet, cada camí correspon a una fase del moviment cap a l'accés obert; que amb el simple fet de l’auto-arxiu no n'hi ha prou, i que cal que els dipòsits proporcionin alguna capacitat de crear marques. De totes maneres, fer això desembocaria, finalment, en la creació d'overlay journals (o bases de dades). Per tant, els dos camins es fusionarien per crear un paisatge d'OA madur.

U-q[(sl(2)over-cap vertical bar 1)] vertex operators, screen currents, and correlation functions at an arbitrary level

Bosonized q-vertex operators related to the four-dimensional evaluation modules of the quantum affine superalgebra U-q[sl((2) over cap\1)] are constructed for arbitrary level k=alpha, where alpha not equal 0,-1 is a complex parameter appearing in the four-dimensional evaluation representations. They are intertwiners among the level-alpha highest weight Fock-Wakimoto modules. Screen currents which commute with the action of U-q[sl((2) over cap/1)] up to total differences are presented. Integral formulas for N-point functions of type I and type II q-vertex operators are proposed. (C) 2000 American Institute of Physics. [S0022-2488(00)00608-3].

Level-one highest weight representation of U-q[sl((N)over-cap vertical bar 1)] and Bosonization of the multicomponent Super t-J model

We study the level-one irreducible highest weight representations of the quantum affine superalgebra U-q[sl((N) over cap\1)], and calculate their characters and supercharacters. We obtain bosonized q-vertex operators acting on the irreducible U-q[sl((N) over cap\1)] modules and derive the exchange relations satisfied by the vertex operators. We give the bosonization of the multicomponent super t-J model by using the bosonized vertex operators. (C) 2000 American Institute of Physics. [S0022- 2488(00)00508-9].

A catalog of HI-selected galaxies from the south celestial cap region of sky

The first deep catalog of the H I Parkes All Sky Survey (HIPASS) is presented, covering the south celestial cap (SCC) region. The SCC area is similar to2400 deg(2) and covers delta < -62&DEG;. The average rms noise for the survey is 13 mJy beam(-1). Five hundred thirty-six galaxies have been cataloged according to their neutral hydrogen content, including 114 galaxies that have no previous cataloged optical counterpart. This is the largest sample of galaxies from a blind H I survey to date. Most galaxies in optically unobscured regions of sky have a visible optical counterpart; however, there is a small population of low-velocity H I clouds without visible optical counterparts whose origins and significance are unclear. The rms accuracy of the HIPASS positions is found to be 1.'9. The H I mass range of galaxies detected is from &SIM;10(6) to &SIM;10(11) M-.. There are a large number of late-type spiral galaxies in the SCC sample (66%), compared with 30% for optically selected galaxies from the same region in the NASA Extragalactic Database. The average ratio of H I mass to B luminosity of the sample increases according to optical type, from 1.8 M-./L-. for early types to 3.2 M-./L-. for late-type galaxies. The H I-detected galaxies tend to follow the large-scale structure traced by galaxies found in optical surveys. From the number of galaxies detected in this region of sky, we predict the full HIPASS catalog will contain &SIM;5000 galaxies, to a peak flux density limit of &SIM;39 mJy (3 σ), although this may be a conservative estimate as two large voids are present in the region. The H I mass function for this catalog is presented in a subsequent paper.

An analysis of US greenhouse gas cap-and-trade proposals using a forward-looking economic model

We develop a forward-looking version of the recursive dynamic MIT Emissions Prediction and Policy Analysis (EPPA) model, and apply it to examine the economic implications of proposals in the US Congress to limit greenhouse gas (GHG) emissions. We find that shocks in the consumption path are smoothed out in the forward-looking model and that the lifetime welfare cost of GHG policy is lower than in the recursive model, since the forward-looking model can fully optimize over time. The forward-looking model allows us to explore issues for which it is uniquely well suited, including revenue-recycling and early action crediting. We find capital tax recycling to be more welfare-cost reducing than labor tax recycling because of its long-term effect on economic growth. Also, there are substantial incentives for early action credits; however, when spread over the full horizon of the policy they do not have a substantial effect on lifetime welfare costs.

Seeding Osteoblastic Cells into a Macroporous Biodegradable CaP/PLGA Scaffold by a Centrifugal Force

This study aims to construct a hybrid biomaterial by seeding osteoblastic cells into a CaP/PLGA scaffold by a centrifugal force. Constructs are evaluated with respect to potential application in bone tissue engineering. Cells adher, spread, and form a layer of tissue lining the scaffold and are capable of migrating, proliferating, and producing mineralized matrix. We have demonstrated that the centrifugal force is highly efficient for constructing a hybrid biomaterial, which acts similarly to bone explants in a cell culture environment. In this way, these constructs could mimic an autogenous bone graft in clinical circumstances. Such a strategy may be useful for bone tissue engineering.

Genetic organization of Pasteurella multocida cap Loci and development of a multiplex capsular PCR typing system

Current serotyping methods classify Pasteurella multocida into five capsular serogroups (serogroups A, B, D, E, and F) and 16 somatic serotypes (serotypes 1 to 16). In the present study, we have developed a multiplex PCR assay as a rapid alternative to the conventional capsular serotyping system. The serogroup-specific primers used in this assay were designed following identification, sequence determination, and analysis of the capsular biosynthetic loci of each capsular serogroup. The entire capsular biosynthetic loci of P. multocida A:1 (X-73) and B:2 (M1404) have been cloned and sequenced previously (J. Y. Chung, Y. M. Zhang, and B. Adler, FEMS Microbiol. Lett. 166:289-296, 1998; J. D. Boyce, J. Y. Chung, and B. Adler, Vet. Microbiol. 72:121-134, 2000). Nucleotide sequence analysis of the biosynthetic region (region 2) from each of the remaining three serogroups, serogroups D, E, and F, identified serogroup-specific regions and gave an indication of the capsular polysaccharide composition. The multiplex capsular PCR assay was highly specific, and its results, with the exception of those for some serogroup F strains, correlated well with conventional serotyping results. Sequence analysis of the strains that gave conflicting results confirmed the validity of the multiplex PCR and indicated that these strains were in fact capsular serogroup A. The multiplex PCR will clarify the distinction between closely related serogroups A and F and constitutes a rapid assay for the definitive classification of P. multocida capsular types

Dynamin-dependent endocytosis is necessary for convergent-extension movements in Xenopus animal cap explants

Cadherin cell-cell adhesion molecules are important determinants of morphogenesis and tissue patterning. C-cadherin plays a key role in the cell-upon-cell movements seen during Xenopus gastrulation. In particular, regulated changes in C-cadherin adhesion critically influence convergence-extension movements, thereby determining organization of the body plan. It is also predicted that remodelling of cadherin adhesive contacts is important for such cell-on-cell movements to occur. The recent demonstration that Epithelial (E-) cadherin is capable of undergoing endocytic trafficking to and from the cell surface presents a potential mechanism for rapid remodelling of such adhesive contacts. To test the potential role for C-cadherin endocytosis during convergence-extension, we expressed in early Xenopus embryos a dominantly-inhibitory mutant of the GTPase, dynamin, a key regulator of clathrin-mediated endocytosis. We report that this dynamin mutant significantly blocked the elongation of animal cap explants in response to activin, accompanied by inhibition of C-cadherin endocytosis. We propose that dynamin-dependent endocytosis of C-cadherin plays an important role in remodelling adhesive contacts during convergence-extension movements in the early Xenopus embryo.

Amino acids 1-20 of the hepatitis C virus (HCV) core protein specifically inhibit HCV IRES- dependent translation in Hep G2 cells, and inhibit both HCV IRES- and cap-dependent translation in HuH7 and CV-1 cells.

A self-modulating mechanism by the hepatitis C virus (HCV) core protein has been suggested to influence the level of HCV replication, but current data on this subject are contradictory. We examined the effect of wild-type and mutated core protein on HCV IRES- and cap-dependent translation. The wild-type core protein was shown to inhibit both IRES- and cap-dependent translation in an in vitro system. This effect was duplicated in a dose-dependent manner with a synthetic peptide representing amino acids 1-20 of the HCV core protein. This peptide was able to bind to the HCV IRES as shown by a mobility shift assay. In contrast, a peptide derived from the hepatitis B virus (HBV) core protein that contained a similar proportion of basic residues was unable to inhibit translation or bind the HCV IRES. A recombinant vaccinia-HCV core virus was used to examine the effect of the HCV core protein on HCV IRES-dependent translation in cells and this was compared with the effects of an HBV core-recombinant vaccinia virus. In CV-1 and HuH7 cells, the HCV core protein inhibited translation directed by the IRES elements of HCV, encephalomyocarditis virus and classical swine fever virus as well as cap-dependent translation, whereas in HepG2 cells, only HCV IRES-dependent translation was affected. Thus, the ability of the HCV core protein to selectively inhibit HCV IRES-dependent translation is cell-specific. N-terminal truncated (aa 1-20) HCV core protein that was expressed from a novel recombinant vaccinia virus in cells abrogated the inhibitory phenotype of the core protein in vivo, consistent with the above in vitro data.
