Los comerciantes del Consulado de México. La adecuación de sus mecanismos de control económico ante los cambios de la segunda mitad del S. XVIII. El caso de las libranzas

ResumenLas Reformas Borbónicas habían comenzado a desmantelar el poder de los comerciantes del Consulado de México. El empleo de las libranzas y de otros mecanismos les devolvió su papel central en la economía de la Nueva España. Así pudieron controlar el comercio interno, ser los intermediarios entre diversos sectores económicos y los monopolistas del comercio exterior, cuya base primordial era el intercambio de plata por mercancías.AbstractThe Bourbon reforms had begun to weaken the power of the merchants of the Consulado de México. The use of libranzas and other mechanisms allowed them to recover a central role in the economic of New Spain. Thus they were able to control domestic trade, to act as intermediaries between various economic sectors and monopolize foreign trade the essential basis for which was the exchange of silver for mercantile commodities.

Mecanismos consensuales y reproducción del orden social reflexiones a propósito de un centenario

Introducción Pese a la obviedad de que el tiempo y los proceso históricos no son  series discontinuas de acontecimientos, los aniversarios de ciertos eventos ejercen sobre nosotros una fascinación que se acentúa cundo la pretérito se ubica a una distancia cronológica secular respecto del presente en el que lo recordamos. Así, todo tiene su centenario: el nacimiento de los longevos o el fallecimiento de personas destacadas, los descubrimientos y las fundaciones, la victoria o la derrota, y cualquier hecho segregado, por  alguna razón, del continúan de la historia. Así, asistimos hoy a la celebración de un centenario al cual se ha dado especial relevancia y determinados contenidos que conviene analizar: la conmemoración de Noviembre de 1889 como “acontecimiento fundador” de la democracia costarricense, par emplear el termino  aplicado por el Doctor Quesada en la introducción a este debate, y que resume bien la significación que se le ha atribuido a los eventos políticos de esta jornada

AS RELAÇÕES DE PODER NO PROCESSO (DES) OCUPAÇÃO DA MATA ATLÂNTICA NA AV. PARALELA, SALVADOR, BAHIA – BRASIL

Este trabalho apresenta uma realidade comum nos grandes centros urbanos no mundo, e que acontece hoje de forma intensa e acelerada na cidade de Salvador, Bahia – Brasil: ocupações regularizadas das áreas de Florestas Tropicais (Mata Atlântica), neste caso, na Avenida Paralela, um dos lugares que vem passando por transformações na sua paisagem natural, com construções de condomínios residenciais para as classes média e alta, shoppings centers, lojas, abertura de ruas e avenidas e, principalmente, a expulsão dos moradores de áreas de “invasão” (favelas) que existem há décadas, como o Bairro da Paz, com a intensificação da especulação imobiliária e, como mecanismo de redução da violência urbana nesta localidade. Para o poder público, o desmatamento e a ocupação informal dessa mesma área há anos atrás era inaceitável, hoje, com a implementação de políticas “publicas”, como o gestado no Plano Diretor de Desenvolvimento Urbano – PDDU, acontece não somente a devastação da Mata Atlântica, bem como o incentivo à ocupação formal e à segregação social dos grupos menos favorecidos.

MECANISMOS DE DESENVOLVIMENTO LIMPO E CONFLITOS LOCAIS

A preocupação deste estudo está relacionada ao contexto das políticas climáticas globais e as relações contraditórias que emerge entre população e projetos de mitigação frente às mudanças do clima. Assim, o presente trabalho apresenta elementos que possibilitam discutir os reflexos dessas políticas internacionais, mais especificamente os projetos de compensação de gases efeito estufa, em relação a populações residentes no entorno de atividades como essa. Como estratégia para aprofundar este debate e ver as diferentes maneiras por meio das quais essas políticas-econômicas ambientais se manifestam territorialmente, analisa-se o “Projeto Bandeirantes de Gás de Aterro e Geração de Energia”, localizado na região metropolitana de São Paulo, Brasil. Trata-se de um projeto de Mecanismo de Desenvolvimento Limpo (MDL) realizado no aterro sanitário Bandeirantes, o maior do país com uma área de 1,5 Km2 e uma reserva estimada de gás bioquímico de 2,4 bilhões de metros cúbicos. Nesse sentido, O presente artigo busca avaliar a disparidade contextual entre as escalas envolvidas, buscando identificar a relação desigual de poderes entre os detentores do mencionado projeto de MDL (empresas multinacionais, bancos e poder público) e a população residente no entorno do projeto investigado.

Neste material aborda-se outros mecanismos de gestão participativa propostos pelo Ministério da Saúde.

Principais mecanismos de gestão participativa

Os processos participativos de gestão fazem parte da dinâmica de diferentes instituições e órgãos do SUS nas três instâncias do governo. Por outro lado, as mesas de negociação entre gestores públicos tem se consolidado como um importante instrumento na prática da gestão participativa. As instâncias de pactuação entre gestores se constituem como espaço de ações compartilhadas, estratégicas e operacionais na gestão do SUS. Enquanto os processos de educação popular em saúde se desenvolvem por meio do diálogo entre movimentos sociais, entidades formadoras e grupos sociais, a fim de fortalecer a participação social no SUS.

Variation of the anal resting pressure induced by postexpiratory apnea effort in patients with constipation

CONTEXT: Intestinal constipation - a common symptom among the general population - is more frequent in women. It may be secondary to an improper diet or organic or functional disturbances, such as dyskinesia of the pelvic floor. This is basically characterized by the absence of relaxation or paradoxical contraction of the pelvic floor and anal sphincter during evacuation. OBJECTIVE: To analyze, by manometric data, the anal pressure variation at rest, during evacuation effort by using the Valsalva maneuver and forced post-expiratory apnea in subjects with secondary constipation. METHODS: Twenty-one patients (19 females - 90.4%) with a mean age of 47.5 years old (23-72) were studied. The diagnosis was performed using anorectal manometry, with a catheter containing eight channels disposed at the axial axis, measuring the proximal (1) and distal (2) portions of the anal orifice. The elevation of the pressure values in relation to the resting with the evacuation effort was present in all patients. The Agachan score was used for clinical evaluation of constipation. The variables studied were: mean anal pressure of the anal orifice for 20 seconds at rest, the effort of evacuation using Valsalva maneuver and the effort of evacuation during apnea after forced expiration, as well as the area under the curve of the manometric tracing at moments Valsalva and apnea. RESULTS: The analysis of the mean values of the anal pressure variation at rest evidenced difference between proximal and distal channels (P = 0.007), independent of the moment and tendency to differ during moments Valsalva and apnea (P = 0.06). The mean of values of the area under the manometric tracing curve showed differences between moments Valsalva and apnea (P = 0.0008), either at the proximal portion or at the distal portion of the anal orifice. CONCLUSION: The effort of evacuation associated with postexpiratory apnea, when compared with the effort associated with the Valsalva maneuver, provides lower elevation of anal pressure at rest by the parameter area under the curve.

Vasopressina e morte encefálica

Brain death results in the breakdown of effective central regulatory mechanisms of cardiocirculatory stability, even in patients with artificial mechanical ventilation, correction of electrolytic and acid-basic disorders and maximal conventional pharmacological support of the circulation. Recent evidences have shown that the fall of vasopressin levels in the blood circulation significantly influences the cardiocirculatory stability of patients with brain death, and its exogenous administration is defended by many authors for the management of multiorgan donor patients. In this brief review we analyse and discuss some experimental and clinical relevant studies about the role of vasopressin in the control of cardiocirculatory stability in brain death, and its potential usefulness in the management of multiorgan donor. We conclude that the role of vasopressin in the pathophysiology of brain death and its usefulness as a pharmacological agent in the management of multiorgan donor are not well elucidated, deserving further investigations.

Efeito da adição de cinza da casca de arroz em misturas cimento-casca de arroz

The rice husk and its ash are abundant and renewable and can be used to obtain alternative building materials. An increase in the consumption of such waste could help minimize the environmental problems from their improper disposal. This study aimed to evaluate the use of ashes as a cargo mineral (filler). However, the rice husk chemically interferes in the conduct of the based cement mixtures. Thus, different mixes cement-rice husk with and without the addition of ash were evaluated in order to highlight the influence of its components (husk; ash), which could otherwise be excluded or be underestimated. Cylindrical samples (test of simple compression and traction by diametrical compression) and samples extracted from manufactured pressed board (test of bending and parallel compression to the surface), were used to evaluate the behavior of different mixtures of components (rice hush; RHA - rice husk ahs). The results of the mechanical tests showed, in general, there is not a statistical difference between the mixtures, which are associated with the chemical suppressive effect of the rice husk ash. The mixture of rice husk of 10 mm, with an addition of 35% of the rice husk ash, is notable for allowing the highest consumption of rice husk and rice husk ash, to reduce 25% the consumption of cement and to allow the storage (without emissions to the atmosphere), around 1.9 ton of CO2 per ton of cement consumed, thus contributing to the reduction of CO2 emissions, which can stimulate rural constructions under an ecological point of view.

Sociedade, cultura, matemática e seu ensino

One of the effects of the globalized world is a strong tendency to eliminate differences, promoting a planetary culture. Education systems are particularly affected, undergoing strong pressure from international studies and evaluations, inevitably comparative, and sadly competitive. As a result, one observes the gradual elimination of cultural components in the definition of education systems. The constitution of new social imaginaries becomes clear; imaginaries empty of historical, geographical and temporal referents, characterized by a strong presence of the culture of the image. The criteria of classification establish an inappropriate reference that has as its consequence the definition of practices and even of education systems. On the other hand, resistance mechanisms, often unconscious, are activated seeking to safeguard and recover the identifying features of a culture, such as its traditions, cuisine, languages, artistic manifestations in general, and, in doing so, to contribute to cultural diversity, an essential factor to encourage creativity. In this article, the sociocultural basis of mathematics and of its teaching are examined, and also the consequences of globalization and its effects on multicultural education. The concept of culture is discussed, as well as issues related to culture dynamics, resulting in the proposition of a theory of transdisciplinar and transcultural knowledge. Upon such basis the Ethnomathematics Program is presented. A critique is also made of the curriculum presently used, which is in its conception and detailing, obsolete, uninteresting and of little use. A different concept of curriculum is proposed, based on the communicative (literacy), analytical (matheracy), and material (technoracy) instruments.

Association of insulin resistance and GLP-2 secretion in obesity: a pilot study

OBJECTIVE: The objective of this pilot study was to determine whether glugagon-like peptide 2 (GLP-2) secretion relates to insulin sensitivity (IS) in obese subjects. SUBJECTS AND METHODS: Twenty four obese subjects [body mass index (BMI) 40.0 ± 3.0 kg/m² (mean ± standard deviation)] were included, nine of which were male, age 43 ± 8 years. Twelve subjects had type 2 diabetes, all treated with oral anti-diabetic agents only. The subjects were submitted to standard meal tolerance test (MTT) for dosage of the curves: glucose, insulin, and GLP-2. Insulin sensitivity was measured by HOMA-IR, and OGIS was derived from the MTT. Spearman linear correlations and partial correlations were obtained. RESULTS: There was an inverse relationship between the GLP-2 secretion and IS: HOMA-IR correlated with GLP-2 AUC (R = 0.504; p = 0.012), and OGIS correlated with GLP-2 incremental AUC (R = -0.54; p = 0.054). The correlation persisted after controlling for BMI. CONCLUSION: We found an association of GLP-2 secretion and insulin resistance (IR). The understanding of the underlying mechanisms may provide future directions in the pharmacological manipulation of incretins, and in the treatment of obesity and related metabolic disorders.
