Análise das condi??es de produ??o de Cidade dos homens: articula??es entre Educa??o e Comunica??o
Schwertner, Suzana Feldens;
Educa??o e Pesquisa , 2007, DOI: 10.1590/S1517-97022007000100004
Abstract: this article proposes connections between communication and education through the investigation of the conditions of production of a television program. starting from the archeological thinking of michel foucault, and highlighting the inseparability of theory and method, it questions the notions of causality and linearity in search of an "origin" for the research object we intend to study. it seeks to signal to multiple conditions for the emergence of the miniseries cidade dos homens (city of men). for that, it selects the programs broadcast in the period between 2002 and 2004 on rede globo, emphasizing the originality of their themes and the contemporaneity of their production. the article also searches the way in which the program presents truths about black youngsters and inhabitants of the city peripheries, characters until recently excluded from the leading roles in fiction shows. the study tries to take into account the strength that social movements have acquired in brazilian society, movements admittedly political, characterized by controversy, and that begin to be part also of the sphere of television. it thus becomes important to consider the way in which the television incorporates the discourse of these movements, and transforms them before returning them to the public. the research work on the television medium, more specifically based on the analysis of images, by entailing an ethical and political stance, becomes a fundamental task for anyone interested in the creation of individuals committed to culture, ethics, and education.

Schwertner, Suzana Feldens;Fischer, Rosa Maria Bueno;
Educa??o em Revista , 2012, DOI: 10.1590/S0102-46982012000100017
Abstract: this study deals with relations between youth and new temporalities, in a digital connectivity era. we discuss the effects of technological changes in youth relationship from research data about time use in relation to cultural consumption of young people in a public school in the metropolitan region of porto alegre (rio grande do sul). to think on those issues, we consider the theoretical framework of carles feixa, carmen leccardi, maria rita kehl, néstor garcía canclini, paulo carrano, juarez dayrell and others. we focus on youth groups, on questioning time and significant subjects for contemporary youth, as role, desire for permanent connection, immediacy of the relationship, and early nostalgia.

O gênero Chinavia Orian (Hemiptera, Pentatomidae, Pentatominae) no Brasil, com chave pictórica para os adultos
Schwertner, Cristiano Feldens;Grazia, Jocélia;
Revista Brasileira de Entomologia , 2007, DOI: 10.1590/S0085-56262007000400005
Abstract: chinavia orian is one of the most speciose pentatominae genera and is distributed in the afrotropical, nearctic and neotropical regions. in brazil, 32 species are recordered, from which 18 are endemic; host-plant association from 18 species are known, and immatures or some life history traits for six species were already described. in this work, we provided a diagnosis and discuss data available on immatures and biology of all species of chinavia found in brazil, including a pictorial key to adult identification. two new synonyms are recognized: acrosternum (chinavia) bellum rolston, 1983 is a junior synonym of chinavia nigrodorsata (breddin, 1903), and acrosternum (chinavia) panizzii frey-da-silva & grazia, 2001 is a junior synonym of chinavia obstinata (st?l, 1860). chinavia nigritarsis (st?l, 1872), formerly a synonym of chinavia gravis (walker, 1867), is reinstated. color habitus ilustrations of all species are provided, the majority taken from type-material. new host-plant associations and distribution data to chinavia species in brazil are presented.

Lucila Isabel Schwertner Sprandel,Helena Heidtmann Vaghetti
Revista Eletr?nica de Enfermagem , 2012,
Abstract: Este artigo teve como objetivo identificar a percep o dos enfermeiros sobre a valoriza o do trabalho e a motiva o profissional. Trata-se de um estudo qualitativo de caráter descritivo desenvolvido entre mar o e maio de 2011, com doze enfermeiros de um hospital universitário no Sul do Brasil. A coleta de dados utilizou entrevistas semiestruturadas e para a verifica o dos mesmos empregou-se a análise temática. Os temas foram estabelecidos a partir dos parametros para a humaniza o do trabalho contidos na Política Nacional de Humaniza o da Assistência Hospitalar referentes à valoriza o do trabalho e motiva o profissional: respeito, reconhecimento, satisfa o e realiza o profissional. Os resultados foram analisados na perspectiva de políticas de humaniza o e dos estudos de Dejours, e indicaram que os enfermeiros vivenciam um conflito com os valores e compromissos do seu trabalho, o que gera a insatisfa o profissional. A presen a dos parametros estudados produz autorrealiza o e sua ausência é entendida como desumaniza o no trabalho.
Descri??o dos estágios imaturos de Chinavia erythrocnemis (Berg) (Hemiptera: Pentatomidae)
Matesco, Viviana C.;Schwertner, Cristiano F.;Grazia, Jocélia;
Neotropical Entomology , 2006, DOI: 10.1590/S1519-566X2006000400009
Abstract: adults and nymphs of chinavia erythrocnemis (berg) were colected on sebastiania commersoniana (baill.) smith & downs in the parque estadual do espinilho in barra do quaraí county, rs, and used to establish a laboratory culture reared on green pods of phaseolus vulgaris l. egg coloration is light-brown, chorion is reticulated and aero-micropylar processes are clubbed and white; mean number of aero-micropylar processes is 61. eggs are very similar to those from other neotropical chinavia species, but the average number of 12 eggs/mass is unique among chinavia species. nymphs are predominantly black, with the distal part of the head, femur, and the basal part of tibia, red. first instar has the dorsal maculae of the head and thorax in red coloration, and the abdomen with a series of 3+3 dorsal white maculae. second to fifth instars have 1+1 white maculae on lateral margins of pronotum and 2+2 white maculae on abdome. fourth and fifth instars show an ovate white maculae in the middle of lateral plates of abdomen. nymph coloration and the size, number and position of the maculae on pronotum and abdomen are diagnostic to c. erythrocnemis.
Morphology of the immatures and biology of Chinavia longicorialis (Breddin) (Hemiptera: Pentatomidae)
Matesco, Viviana C;Schwertner, Cristiano F;Grazia, Jocelia;
Neotropical Entomology , 2009, DOI: 10.1590/S1519-566X2009000100007
Abstract: chinavia longicorialis (breddin) is recorded only in brazil, argentina and uruguay on host plants of at least three different families. adults and nymphs were reared under standard controlled conditions (24 ± 1°c; 70 ± 10% rh; 12hl:12hd), and fed on green beans (phaseolus vulgaris l.). eggs and first instars of c. longicorialis are very similar to those of other species of chinavia; however, the presence of orange maculae at the thoracic pleura is exclusive of first instars of c. longicorialis. third to fifth instars have abdominal maculae divided by pseudo-sutures, a diagnostic feature of c. longicorialis nymphs. light and dark morphs were observed for third, fourth and fifth instars. head width measurements did not overlap between consecutive instars. the most frequent size of an egg clutch was 14; we suggest the adoption of the mode as the best and useful estimate of the egg clutch size for pentatomidae. average duration of the immature stages (egg to adult) was 39.4 ± 3.20 days. the high mortality observed from second to fifth instar (82.4%) and the lack of reproduction of the second generation indicate that green beans are unsuitable to proper development and reproduction of c. longicorialis by itself.
Descri??o dos Estágios Imaturos de Acrosternum (Chinavia) ubicum Rolston (Heteroptera: Pentatomidae) e Efeito do Alimento no Tamanho e Colora??o das Ninfas
SCHWERTNER, CRISTIANO F.;ALBUQUERQUE, GILBERTO S.;GRAZIA, JOCéLIA;
Neotropical Entomology , 2002, DOI: 10.1590/S1519-566X2002000400009
Abstract: here we describe the immature stages of acrosternum (chinavia) ubicum rolston, and test the effect of the host plant on the size and coloration of the nymphs, by feeding them with developing fruits of crotalaria incana l., phaseolus vulgaris l., glycine max (l.) merril, abelmoschus esculentus (l.), and lycopersicon esculentum mill. a. ubicum immatures are very similar to those from other neotropical acrosternum species. the egg coloration varies from ochre to brown; the chorion is reticulated and the micropylar processes are clubbed and white. first to third instars are predominantly dark and the abdomen has a series of creamy to white maculae. second to fifth instars show red to orange-red maculae on each of the dorso-lateral margins of the pronotum and mesonotum. in the fourth and fifth instars, these maculae are wider, and may also appear on the margins of the jugae, on the pronotum and mesonotum, and in the middle of the mesal and lateral plates of the abdomen. the orange-red coloration of these dorsal maculae seems specific to a. ubicum, but additional studies with other species of the genus are necessary to validate it as a good diagnostic characteristic. fourth and fifth instars presented light and dark morphs, and their proportion varied according to the type of plant used as food. from the third instar on, the food also affected most of the morphometric parameters measured, i.e., length and width of the body, pronotum and scutelum, and antennal length; only the rostrum length remained unchanged.
Endemism analysis of Neotropical Pentatomidae (Hemiptera, Heteroptera)
Ferrari, Augusto;Paladini, Andressa;Schwertner, Cristiano Feldens;Grazia, Jocelia;
Iheringia. Série Zoologia , 2010, DOI: 10.1590/S0073-47212010000400018
Abstract: the definition of areas of endemism is central to studies of historical biogeography, and their interrelationships are fundamental questions. consistent hypotheses for the evolution of pentatomidae in the neotropical region depend on the accuracy of the units employed in the analyses, which in the case of studies of historical biogeography, may be areas of endemism. in this study, the distribution patterns of 222 species, belonging to 14 pentatomidae (hemiptera) genera, predominantly neotropical, were studied with the analysis of endemicity (ndm) to identify possible areas of endemism and to correlate them to previously delimited areas. the search by areas of endemism was carried out using grid-cell units of 2.5° and 5° latitude-longitude. the analysis based on groupings of grid-cells of 2.5° of latitude-longitude allowed the identification of 51 areas of endemism, the consensus of these areas resulted in four clusters of grid-cells. the second analysis, with grid-cells units of 5° latitude-longitude, resulted in 109 areas of endemism. the flexible consensus employed resulted in 17 areas of endemism. the analyses were sensitive to the identification of areas of endemism in different scales in the atlantic forest. the amazonian region was identified as a single area in the area of consensus, and its southeastern portion shares elements with the chacoan and paraná subregions. the distribution data of the taxa studied, with different units of analysis, did not allow the identification of individual areas of endemism for the cerrado and caatinga. the areas of endemism identified here should be seen as primary biogeographic hypotheses.
