The macroeconomic limits of income's policy in a dependent country : The need and possibilities for radical reforms in social policies in Argentina after the crisis (2001-2008)

This article analyzes incomes policies in Argentina. In particular, we study the role of social and wages policies during the years 2001-2008. In this regard we’ll comment on the effectiveness of policies towards the reduction of poverty and show how they are strongly conditioned by macroeconomic policy objectives and by Argentina’s mode of capitalist participation in the world’s economy. Our argument is that the peripherical position of Argentina’s economy and the correlative policy of undervalued real exchange rate and public sector’s fiscal surplus, limit the government’s ability to allow for a clearly pro-poor income’s policy (including social and wages policies). The need for “competitiveness” and foreign debt payments puts immediate pressure on wages, incomes and labour conditions for the working people.Facultad de Humanidades y Ciencias de la Educació

Encapsulation of active pharmaceutical ingredients in lipid micro/nanoparticles for oral administration by spray-cooling

Nanoencapsulation via spray cooling (also known as spray chilling and spray congealing) has been used with the aim to improve the functionality, solubility, and protection of drugs; as well as to reduce hygroscopicity; to modify taste and odor to enable oral administration; and many times to achieve a controlled release profile. It is a relatively simple technology, it does not require the use of low-cost solvents (mostly associated to toxicological risk), and it can be applied for lipid raw materials as excipients of oral pharmaceutical formulations. The objective of this work was to revise and discuss the advances of spray cooling technology, with a greater emphasis on the development of lipid micro/nanoparticles to the load of active pharmaceutical ingredients for oral administration.This research was funded by the Portuguese Science and Technology Foundation (FCT/MCT) and European Funds (PRODER/COMPETE), under the project reference UIDB/04469/2020 (strategic fund), co-financed by FEDER, under the Partnership Agreement PT2020, granted to Eliana B.

Participatory Farmer Evaluation of Stem borer Resistant Maize varieties in three maize growing ecologies of Kenya

Insect Resistant Maize for Africa Project (IRMA) aims at developing and deploying insect resistant maize varieties to reduce grain losses due to insect pests. As part of incorporating farmer’s perceptions and improving the adoption of the developed varieties, participatory approaches are adopted. The paper analysis farmer’s preferences of maize germplasm developed through conventional breeding. The paper uses data collected from evaluations conducted at the end of 2006 April and October rains. Nine stem borer resistant maize varieties were evaluated alongside six commercial checks in the moist transitional zones (East and West) at vegetative and harvest stage, while in the dry transitional zone and dry mid altitude zones, 6 new varieties were evaluated together with four commercial checks at harvest stage. Each variety was assessed on a scale of 1(very poor) to 5 (very good) based on key criteria generated in earlier group discussions with farmers and overall score. Data was analyzed using ordinal regression model of Social Package for Social Sciences (SPSS). In DT zone, Katumani, CKIR06007 and CKIR06008 were more preferred to the checks based on overall score. CKIR06008 was also more preferred on yield and tolerance to insect pest criteria, while CKIR04002, CKIR06009, and CKIR04003 were perceived more superior to local check based on tolerance to insect pests. In moist transitional zone Embu only CKIR06005 was more preferred (p<0.01) to the check at harvest stage in April 2006 season based on early maturity. While there was no preference for the new varieties at vegetative stage in Embu in October rains 2006 season, a number of new varieties CKIR06001, CKIR06002, CKIR06003, CKIR06004, and CKIR06005 were more preferred based on early maturity at harvest in October rains 2006 season. In the moist transitional zone (west), CKIR06005 and CKIR06005 were more preferred on maturity criteria but CKIR06004 also had good attributes in terms of cob size vegetative stage in April rains 2007. We conclude that farmers perceive some varieties to have good tolerance to insect pests in addition to good yield and maturity characteristics attributes, which are critical to the farmers in the adoption of new varieties.Crop Production/Industries,

Flaxseed gum-biopolymers interactions driving rheological behaviour of oropharyngeal dysphagia-oriented products

Viscosity-modified diet through thickeners is used as a strategy to circumvent swallowing problems by oropharyngeal dysphagia patients. Most commercial products present xanthan and starch in their formulations, but flaxseed gum (FG) is a potential thickener for liquid food that provides additional health benefits. FG was mixed either with modified starch (MS) and/or xanthan gum (XG), varying biopolymersâ concentration according to a central composite rotational design in which rheological and colour properties in water were the evaluated responses. All formulations showed a shear time-independent and shear-thinning behaviour, mainly influenced by XG and MS concentrations. In oscillatory measurements, the formulations presented a prevailing elastic character attributed to MS and mainly to XG, which despite the lower concentration in which it was incorporated, exerted a similar influence on this rheological property. However, the increase of FG concentration was the most significant factor influencing viscosity, but also favoured an increase of both viscoelastic moduli mainly G'. Analysis of the microstructure disclosed different network structures as a result of biopolymers interactions, which was related to rheological behaviour giving insights to design new thickeners for dysphagia management. In addition, the amount of glucose released after in vitro digestion was evaluated and compared to a commercial MS-based thickener. Interestingly, the commercial formulation showed a glucose release significantly higher than the proposed FG/MS/XG-based formulations. These results open the opportunity to tailor the rheological characteristics of food systems by adding and combining natural ingredients, improving technological and nutritional properties.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brasil (CAPES) (Finance code 001); São Paulo Research Foundation - FAPESP (Process numbers 2016/05448–8; 2011/51707–1; EMU 2009/54137–1; 2007/58017–5; 2006/03263–9; 2004/08517–3) and by the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq - Process 307168/2016–6).

Association of severe hypertension with pneumonia in elderly patients with acute ischemic stroke

Pneumonia is one of the most frequent complications in elderly patients with acute ischemic stroke. Although severe hypertension is often observed in the early phase of acute stroke, there are few studies of acute hypertension as a factor influencing the incidence of stroke-associated pneumonia (SAP) in elderly subjects with acute ischemic stroke. To assess the association of acute phase blood-pressure elevation with the incidence of SAP, we compared 10 elderly patients with acute ischemic stroke complicated with severe hypertension (⩾200/120 mm Hg) with 43 patients with moderate hypertension (160–199/100–119 mm Hg), as well as with 65 control normotensive or mildly hypertensive (<160/100 mm Hg) controls on admission. Data were collected on known risk factors, type of ischemic stroke and underlying chronic conditions. The significance of differences in risk factors was analyzed using univariate and multivariate comparisons of 38 SAP cases and others, 8 SAP death cases and others, and 28 patients with poor outcome associated with in-hospital death or artificial feeding at discharge and others. After adjustment for potential confounding factors, the relative risk estimates for SAP, SAP death and poor outcome were 2.83 (95% confidence interval 1.14–7.05), 5.20 (1.01–26.8) and 6.84 (1.32–35.4), respectively, for severe hypertension relative to normotensive or mildly hypertensive controls. We conclude that severe hypertension on admission is an independent predictive factor for SAP in elderly patients with acute ischemic stroke

Análise da postura craniocervical de crianças respiradoras bucais após tratamento postural em bola suíça

The study aimed to evaluate the craniocervical posture of mouth breathing children after postural treatment on swiss ball. Twelve mouth breathing children were undergone to a postural reeducation protocol through stretching and strengthening exercises on swiss ball, diaphragmatic stimulation and stretching of the inspiratory accessory muscles. Craniocervical posture was evaluated through biophotogrammetry analysis. Forward head position was measured through an angle formed by the points in the tragus and in the spinous process of the seventh cervical vertebra with a horizontal line. Cervical column curvature was taken by the horizontal distance from a vertical line passing through the thoracic kyphosis apex to the point of the greatest cervical curvature concavity. Pictures were taken before and after ten treatment sessions. The normality of the variables was tested by Shapiro-Wilk test and the Student's t -test was used to determine differences in variables between assessments. It was considered a significance level of 5% (pO estudo teve como objetivo avaliar a postura craniocervical de crianças respiradoras bucais após tratamento postural em bola suíça. Doze crianças respiradoras bucais foram submetidas a um protocolo de reeducação postural constituído por exercícios de alongamento e fortalecimento muscular sobre a bola suíça, estimulação diafragmática e alongamento dos músculos acessórios da inspiração. A postura craniocervical foi avaliada através da análise biofotogramétrica. A posição da anteriorização da cabeça foi aferida por meio do ângulo formado pelos pontos localizados no tragus direito e no processo espinhoso da sétima vértebra cervical com a linha horizontal. A curvatura cervical foi avaliada pela distância horizontal de uma linha vertical tangenciando o ápice da cifose torácica e o ponto de maior concavidade da curvatura cervical. As fotografias foram obtidas antes e após dez atendimentos. A normalidade das variáveis foi verificada a partir do teste Shapiro-Wilk. Para as comparações entre as médias foi utilizado o teste t de Student para amostras dependentes admitindo-se nível de significância de 5% (
