How to manage macroeconomic policies to foster growth and employment and prevent financial and external crises

My presentation focuses on the implementation of a macroeconomic policy regime which, I believe, is capable of simultaneously attaining several targets, including the promotion of growth and employment and the prevention of external and financial crises.

The price of threat: the role of identity-safe marketplaces in predicting intergroup price sensitivity

In field experiments with subjects living either inside or outside Brazilian slums (n=955), we show that consumers living in slums are less price sensitive, in opposition with recent price sensitivity research. Comparing slum and non-slum dwellers, we found that negatively stereotyped consumers (e.g. slum dwellers) were more likely to pay higher amounts for friendlier customer service when facing social identity threats (SITs) in marketplaces such as banks. The mechanism which makes them less price sensitive is related to the perception of how other people evaluate their social groups, and we argue that they pay more because they are seeking identity-safe commercial relationships. This work, besides extending the literature in SITs, presents a perspective for the exchange between economics and psychology on price sensitivity, showing that consumers living in slums are willing to pay more to avoid possibly social identity threating experiences.

Hemiparesia congênita e adquirida na criança: interrelação entre presença de crises epilépticas, os achados eletrencefalográficos e de neuroimagem por ressonância nuclear magnética

The purpose of this paper was to study patients with congenital and acquired hemiparesis, their clinical aspects, the presence or not of epileptic seizures, and electroencephalographic (EEG) and Magnetic Resonance Imaging (MRI) findings. We analyzed the interrelation between etiology, the presence and seriousness of epileptic seizures (ES) and the possible causes of refractoriness. This is a prospective study using the clinical diagnosis of a child neurologist, who attested to the presence of unilateral motor lesions. We compared the electroencephalographic findings in patients with or without epileptic seizures, and investigated if among the former, these seizures were controlled or not, their likely etiology and risks of refractoriness. EEG background activity on the lesion and contralateral side was analyzed, in addition to the presence of concomitant epileptiform activity. Encephalon MRIs of all the patients were studied to correlate etiology and the control or not of epileptic seizures. The disorganization of bilateral EEG activity correlated with the difficult-to-control epileptic seizures. Suitably organized background activity contralateral to the lesion is a good prognosis in relation to epileptic seizures. Focal epileptogenic activity does not necessarily predispose to epileptic manifestation. The MRI is more important in determining etiology than in prognosing epileptic seizures. This study used a multidisciplinary approach involving child neurologists, a physical therapist and a neuroradiologist. This meets the criteria of multidisciplinarity of the Postgraduate Program in Health Sciences

Determinação dos fatores neuroepidemiológicos das crises convulsivas em recém nascidos internados em unidades de terapia intensiva

O objetivo do nosso projeto foi determinar as características dos recém nascidos com crises convulsivas internados em unidades de terapia intensiva. Foi realizada uma pesquisa multicêntrica, observacional, prospectiva, cuja população alvo foi os recém nascidos com crises convulsivas internados em unidades de terapia intensiva, envolvendo equipe multidisciplinar constituída por neurologista infantil, neonatologistas, intensivistas pediátricos, enfermeiros, técnicos de enfermagem e fisioterapêutas. As crises foram definidas pelo critério clínico, com classificação de Volpe. Variáveis relacionadas à gestação, ao parto, características dos recém nascidos, aspectos das crises convulsivas e mortalidade foram analisadas. Estatística: descritiva (freqüências, medidas de tendência central e dispersão) e análise (teste de probabilidade, teste de risco e de acurácia). Comparamos as crises clínicas entre os recém nascidos de termo e pretermo e observamos diferenças com significância estatística na idade de início das crises, mais tardia nos prematuros, na etiologia predominante: hemorragia peri-intraventricular no prematuro e encefalopatia hipóxico-isquêmica no termo e tipo clínico de crise, clônica no pretermo e sutil no termo. Os testes de acurácia utilizados para determinar se o tipo clínico de crise convulsiva é predictor da etiologia da mesma não revelaram resultados positivos. Quanto às características associadas à mortalidade de prematuros com crise convulsiva, observamos associação entre ventilação mecânica e pneumonia com a mortalidade. Existem diferenças clínicas quando comparamos os recém nascidos pretermo e de termo com crises convulsivas, confirmando dados da literatura

O progama empregador de última instância: Sua relevância em tempos de crises financeiras e sua aplicabilidade ao Brasil.

This dissertation aims to continue the work developed previously concerning the properties of the employer of last resort program (ELR) that would be able to promote a complete elimination of the involuntary unemployment from the economy, so much of the unemployment generated by structural problems as for problems of the conjuncture, as the present world financial crisis. Besides, it intends to deepen the study concerning the applicability of that program to the Brazilian economy, estimating their potential target population in the country and the cost with the workers' remuneration. It was presented the ELR theoretical-conceptual structure and a debate concerning their economic viability; the program properties that turn it more efficient than the onetary and fiscal policies (PMFs) in the fight against involuntary unemployment in times of financial crises; a study on its applicability to the Brazilian socioeconomic specificities and an estimate of their potential target population and of the annual wage cost in the country, as a whole, and in the specific case of the Northeast region and of the state of Rio Grande do Norte.

Vozes sociais e dimensão ética da lingüística aplicada: a construção discursiva da área nos CBLAs

This research deals with Applied Linguistics and its structure as a scientific field, in compliance with knowledge produced within the range of the Brazilian Congresses of Applied Linguistics (CBLA). The purpose of this research is to understand the meanings disclosed by the voices that make up the scientific discourse on this field, pointing toward its course of development, the ethical position that is peculiar to it and how this position is represented in its scientific practice. The scientific discourse typical of the production of knowledge of Applied Linguistics is now construed as leading to practices that define the production of this field of learning whose object is to study man and man s relationship to language. Theoretical groundwork is anchored on the work the Social Sciences have developed on the paradigmatic crises of science and the social changes resulting from modern and post-modern times, on Applied Linguistics researches on the identity of the field of study, its courses and ethics, and on the bakhtinian theory that supports a view of language as a social practice built under the aegis of the subject s ethics and responsibility. The corpus of this work comprises qualitative and quantitative data made into articles presented at the CBLA. The research methodology conforms to the interpretive paradigm and has the concept of social voices as its category of analysis. Results point towards the progress of Applied Linguistics that, from its role as a mediator discipline between linguistic theory and practical applications, is assuming a position in a field of study of its own, independent, with transdisciplinary characteristics, pursuing through its quests and redefinitions to get closer to the dimension of life and assuming the ethical position of taking on responsibility for its doings and sayings

The Jacobi identity for Dirac-like brackets

For redundant second-class constraints the Dirac brackets cannot be defined and new brackets must be introduced. We prove here that the Jacobi identity for the new brackets must hold on the surface of the second-class constraints. In order to illustrate our proof we work out explicitly the cases of a fractional spin particle in 2 + 1 dimensions and the original Brink-Schwarz massless superparticle in D = 10 dimensions in a Lorentz-covariant constraints separation.

Identity by descent and candidate gene mapping of Richieri-Costa and Pereira syndrome

The Richieri-Costa-Pereira syndrome is a rare autosomal recessive disorder characterized by short stature, Robin sequence, cleft mandible, pre/postaxial anomalies and clubfoot. of 15 families reported with this disorder 14 are from Brazil suggesting a founder effect. We studied 15 families using identity-by-descent as a hypothesis to attempt gene localization We have examined through linkage analysis 497 polymorphicmarkers and also performed direct sequencing of exons for 10 candidate genes selected on the basis of their expression in the developing mandible and limb. No evidence for allele sharing at any locus tested or mutations in candidate genes was found. Additional higher resolution mapping, new families and other candidate genes might improve future chances of gene identification. (C) 2003 Wiley-Liss, Inc.

An old taxonomic dilemma: the identity of the western south Atlantic lebranche mullet (Teleostei: Perciformes: Mugilidae)

The identification of the lebranche mullet in the western south Atlantic has long been problematical. In most recent works either Mugil liza Valenciennes and M. platanus Gunther, 1880 or M. liza and M. cephalus Linnaeus, 1758 were recognized from the region and more rarely the occurrence of only one species has been proposed but without sufficient morphological, biochemical or molecular data to allow the designation of the taxonomically appropriate name. Analysis of meristic and morphometric data taken from samples collected from Venezuela to Argentina, clearly indicates that there is only one species of lebranche mullet in the Caribbean Sea region and the Atlantic coast of South America and that Mugil liza is the appropriate name. The comparison of the combined data from all the samples of M. liza with the data taken from one sample of M. cephalus that originated in the Mediterranean, the possible locality from which type specimens were collected (Eschmeyer and Fricke, 2009), revealed significant differences indicating that they are different species. It is also suggested that individuals from the western north Atlantic identified as M. cephalus might represent a population of M. liza in this region.

On the identity of Hyla strigilata Spix, 1824 (Anura : Hylidae): redescription and neotype designation for a ghost taxon

Recent field work in Atlantic Rain Forest patches in the southern region of the State of Bahia, Brazil, resulted in the discovery of some populations of an unidentified species of the Scinax catharinae group. An extensive literature review, along with the examination of specimens and distribution patterns of all known species of this group, showed that Hyla strigilata Spix, 1824, a long confused species with lost type material, is an available name for the specimens from Bahia. In order to clarify the taxonomic problems surrounding this taxon, the nomenclatural history of Hyla strigilata is reviewed and a neotype is designated, described, and figured. The association of this name to extant populations from southern Bahia and its consequent stabilization is considered important since it is the type species of the genus Ololygon, a name available for the clade of Scinax catharinae. Data on habits, habitat, and geographic distribution are also presented.

Lobe identity in the Mongolian gerbil prostatic complex: A new rodent model for prostate study

Knowledge of structural and physiological differences among the prostatic lobes (PL) is the basis for development of experimental studies in traditional laboratory rodents. Although Mongolian gerbil reproductive organs have been increasingly investigated, its prostate structure is far from being properly known, and investigations of this organ focused on the ventral lobe (VL). Thus, the present study provides a thorough morphological description of prostatic complex in the male adult gerbil on the basis of topographic, histological, and ultrastructural analysis and ductal branching. Like other rodents, four pairs of PL were observed. However, in contrast to the rat and mouse, the VL is the least voluminous component and the dorsolateral lobe (DLL) is the most prominent and spatially isolated from remaining PL. The occurrence of a dorsal lobe (DL), hidden between bladder and insertion of seminal vesicles, has not been mentioned in previous reports with Mongolian gerbil. Collagenase digestion followed by microdissection revealed that, except for DL, which has a tubularacinar organization, all PL exhibit tubular organization and variable ductal branching. Distinct histological and ultrastructural features such as secretory epithelium, aspect of luminal secretion and stromal organization are reported for each PL and are confirmed by morphometric and stereological methods. Histological sections showed at least three intralobar segments in VL and DL. Ultrastructural analysis evidenced that, although luminal epithelial cells of PL share typical features of exocrine secretory cells, there are striking lobe phenotypical variations. Both merocrine and apocrine pathways are observed in variable rates in all PL, with the predominance of the former in the DLL and the latter in the CG. The morphological observations presented herein point to distinct structural identities for each PL, which probably reflects,specific functional compromise of seminal fluid secretion. These data also point to the gerbil as a good model for investigations concerning the regulation of prostate development and homeostasis, mainly with regard to the dorsal and dorsolateral PL.
