"O Brasil n?o é só doen?a": o programa de saúde pública de Juscelino Kubitschek
Hochman, Gilberto;
História, Ciências, Saúde-Manguinhos , 2009, DOI: 10.1590/S0104-59702009000500015
Abstract: analyzes the public health program that juscelino kubitschek presented while running for president and its dialogue with interpretations that identified brazil as an ailing country that should be recovered through public medicine. the proposals and goals contained in kubitschek's healthcare program, as released during his 1955 campaign, serve as the main sources for this analysis. they also were key to establishing this dialogue, which was both prompted and shaped by a national and international context characterized by the post-war idea of development and public health optimism. within the context of his development project, the article looks at how kubitschek elaborated the themes of the centrality of rural endemic disease and the abandonment of the rural worker, both dear to the sanitary movement in the 1910s. it also underscores how kubitschek the candidate endeavored to link health and development within this arena of government policy.
Logo ali, no final da avenida: Os sert?es redefinidos pelo movimento sanitarista da Primeira República
Hochman, Gilberto;
História, Ciências, Saúde-Manguinhos , 1998, DOI: 10.1590/S0104-59701998000400012
Abstract: between 1910 and 1920, the brazilian sanitation movement endeavored to redefine the boundaries between backlands and coast, interior and cities, rural brazil and urban brazil, in accordance with what sanitarians then deemed the nation?s key problem: public health. the movement relentlessly defended an essentially medical-political definition of these borders: in the eyes of sanitarian physicians, the backlands were characterized by the absence of government and the omnipresence of endemic diseases. through an intensive public opinion campaign, doctors and sanitarians convinced the political elites that the backlands were closer than they thought. this rural sanitation drive had political consequences: it laid the foundations for the first public health initiatives of national scope during the 1920s.
Vacina??o, varíola e uma cultura da imuniza??o no Brasil
Ciência & Saúde Coletiva , 2011, DOI: 10.1590/S1413-81232011000200002
Abstract: the aim of this paper is to discuss the emergence and establishment of a "culture of immunization" in the contemporary brazil from the eradication of smallpox. this culture is associated with a long process of introduction of vaccines, vaccination campaigns and mass vaccination undertaken by the brazilian government since the late nineteenth century. particular importance is attributed to the campaign to eradicate smallpox in brazil (1966-1973). the experience of mass vaccination of the population against smallpox is contrasted with episodes of resistance as the "revolt against the vaccine", and regarded as crucial in shaping new policies and new understandings about the role of immunization in public health and its place in society brazil.
O sal como solu??o? políticas de saúde e endemias rurais no Brasil (1940-1960)
Hochman, Gilberto;
Sociologias , 2010, DOI: 10.1590/S1517-45222010000200007
Abstract: the article main objective is to analyze and compare the policies surrounding the use of salt in the treatment of two major diseases that raging in rural areas and the amazon in brazil during the national-developmentist period: the endemic goiter and malaria. although they are very different diseases, the first is a carential disease and the second a parasitic disease, the struggle of doctors and nutritionists for the obligatory iodisation of table salt consumed in the country inspired the proposal of a cooking salt mixed with chloroquine and its free distribution in malarial areas where the use of ddt would not be effective. methods designed to be simple - and thus efficient - to control and even eliminate such diseases, the use of cooking salt as vehicle to supply iodine and an antimalarial drug to the population collides with cognitive, economic, social and cultural factors. some variables organize the historical analysis of these health programs: the consensus on the etiology of the disease, the degree of institutionalization of the community of specialists and their organization, the place of disease on the agenda of international health organizations, the locus of policy making and the existence of leadership scientific and policy formulation and conduct of policy and the consumption patterns of target populations.

Recent Results on Charm Photoproduction
Don Hochman
Physics , 2000, DOI: 10.1063/1.1402850
Abstract: Photoproduction of $D_s^{\pm}$ mesons has been measured in the ZEUS detector at HERA and compared with predictions of NLO pQCD calculations. The ratio of $D_s^{*\pm}$ to $D^{*\pm}$ cross sections has been compared to results from $e^{+}e^{-}$ experiments. Orbitally excited P-wave charm mesons have been observed in the $D^{*\pm}\pi^{\mp}$ final state. The fraction of $D^{*\pm}$ 's originating from these mesons has been calculated and compared with that from $e^{+}e^{-}$ interactions. No evidence for radially excited mesons decaying to $D^{*\pm}\pi^{+}\pi^{-}$ was found. The inelastic production of J/$\psi$ mesons has been measured and compared to LO and NLO pQCD predictions.
Genericity in Topological Dynamics
Michael Hochman
Mathematics , 2006, DOI: 10.1017/S0143385707000521
Abstract: We study genericity of dynamical properties in the space of homeomorphisms of the Cantor set and in the space of subshifts of a suitably large shift space. These rather different settings are related by a Glasner-King type correspondence: genericity in one is equivalent to genericity in the other. By applying symbolic techniques in the shift-space model we derive new results about genericity of dynamical properties for transitive and totally transitive homeomorphisms of the Cantor set. We show that the isomorphism class of the universal odometer is generic in the space of transitive systems. On the other hand, the space of totally transitive systems displays much more varied dynamics. In particular, we show that in this space the isomorphism class of every Cantor system without periodic points is dense, and the following properties are generic: minimality, zero entropy, disjointness from a fixed totally transitive system, weak mixing, strong mixing, and minimal self joinings. The last two stand in striking contrast to the situation in the measure-preserving category. We also prove a correspondence between genericity of dynamical properties in the measure-preserving category and genericity of systems supporting an invariant measure with the same property.
Upcrossing inequalities for stationary sequences and applications
Michael Hochman
Mathematics , 2006, DOI: 10.1214/09-AOP460
Abstract: For arrays $(S_{i,j})_{1\leq i\leq j}$ of random variables that are stationary in an appropriate sense, we show that the fluctuations of the process $(S_{1,n})_{n=1}^{\infty}$ can be bounded in terms of a measure of the ``mean subadditivity'' of the process $(S_{i,j})_{1\leq i\leq j}$. We derive universal upcrossing inequalities with exponential decay for Kingman's subadditive ergodic theorem, the Shannon--MacMillan--Breiman theorem and for the convergence of the Kolmogorov complexity of a stationary sample.
Rohlin properties for $Z^d$-actions on the Cantor set
Michael Hochman
Mathematics , 2009, DOI: 10.1090/S0002-9947-2011-05319-5
Abstract: We study the space of continuous $Z^d$-actions on the Cantor set, particularly questions on the existence and nature of actions whose isomorphism class is dense (Rohlin's property). Kechris and Rosendal showed that for $d=1$ there is an action on the Cantor set whose isomorphism class is residual. We prove in contrast that for $\geq 2$ every isomorphism class is meager; on the other hand, while generically an action has dense isomorphism class and the effective actions are dense, no effective action has dense isomorphism class. Thus for $d \geq 2$ conjugation on the space of actions is topologically transitive but one cannot construct a transitive point. Finally, we show that in the space of transitive and minimal actions the effective actions are nowhere dense, and in particular there are minimal actions that are not approximable by minimal SFTs.
Universality in Multidimensional Symbolic Dynamics
Michael Hochman
Mathematics , 2009, DOI: 10.3934/dcdss.2009.2.301
Abstract: We show that in the category of effective $Z$ dynamical systems there is a universal system, i.e. one that factors onto every other effective system. In particular, for d $\geq 3$ there exist d-dimensional shifts of finite type which are universal for 1-dimensional subactions of SFTs. On the other hand, we show that there is no universal effective $Z^d$-system for $d>1$, and in particular SFTs cannot be universal for subactions of rank $d>1$. As a consequence, a decrease in entropy and Medvedev degree and periodic data are not sufficient for a factor map to exists between SFTs. We also discuss dynamics of cellular automata on their limit sets and show that (except for the unavoidable presence of a periodic point) they can model a large class of physical systems.
