Authors: Santos Cidalia de Lourdes Moura , Rodrigues Celso Luiz Pereira , Silva Luiz Bueno da , Bakke Hanne Alves , Leite Alexandre Santos de Moura , Leal Maria Marta de Araújo
Published: April 2011

O objetivo deste trabalho é verificar que fatores têm interferência direta no estresse de profissionais médicos em João Pessoa (PB) baseado nas variáveis de uma adaptação do Inventário de Estresse em Enfermeiros (IEE) proposto por Stacciarini and Trocoli (2000). Os dados foram coletados por meio de um questionário semiestruturado, composto por perguntas de identificação do colaborador seguidas de 44 questões de múltipla escolha, aplicado a 391 médicos que trabalhavam em hospitais. As variáveis não métricas foram submetidas à análise fatorial, que indicou a presença de oito fatores para o estresse entre esses profissionais. Nesses fatores, é possível apontar variáveis que apresentam maior impacto, a saber: relacionamento com a equipe médica, relacionamento com os colegas médicos, trabalhar em equipe, relacionamento com a chefia, trabalhar em instalações físicas inadequadas, falta de material necessário ao trabalho e trabalhar em horário noturno. Esses resultados podem contribuir para o gerenciamento do estresse entre médicos.
Preparação psicológica para admissão hospitalar de crianças: uma breve revisão
Authors: Doca Fernanda Nascimento Pereira , Costa Junior Áderson Luiz
Published: April 2011

A preparação psicológica constitui uma ampla modalidade de intervenção, que inclui diferentes procedimentos e técnicas, recomendadas por pesquisadores em psicologia da saúde e da psicologia pediátrica para uso com pacientes e familiares expostos a condições potencialmente estressantes. Entre os benefícios apontados consta a redução de efeitos aversivos associados à experiência de hospitalização, o aumento dos índices de adesão ao tratamento e o desenvolvimento de estratégias mais eficientes de enfrentamento. No entanto, observa-se que a literatura ainda não dispõe de uma sistematização metodológica suficiente que permita apontar relações funcionais precisas entre intervenção e efeitos. Este trabalho tem por objetivo efetuar uma revisão bibliográfica sobre o tema da preparação psicológica para hospitalização da criança, destacando princípios metodológicos que envolvem o planejamento e a execução da intervenção e propor, também, um modelo de programa de preparação psicológica para admissão hospitalar infantil.
Sentido de número na infância: uma interconexão dinâmica entre conceitos e procedimentos
Authors: Barbosa Heloiza Helena de Jesus
Published: April 2011

A presente revisão tem o objetivo de analisar o que estudos acadêmicos e experimentais têm revelado sobre os processos cognitivos de desenvolvimento envolvidos na conceituação de número pela criança. Presentemente, dois grupos de orientações teóricas opostas têm argumentado sobre a natureza da habilidade numérica das crianças. Apesar de inconcluso o debate, estudos revistos neste artigo parecem apontar para a existência de uma interconexão entre conceitos e procedimentos no processo de construção do sentido de número. Veremos, também, como a qualidade do sentido de número construído pelas crianças pode estar relacionada com o desempenho acadêmico na área da matemática.
Diferenças de gênero e valores relativos ao trabalho
Authors: Silva Margareth Ribeiro Machado Santos e , Mendonça Helenides , Zanini Daniela Sacramento
Published: April 2011

Este estudo investiga as diferenças no estabelecimento das prioridades axiológicas laborais e a satisfação das metas motivacionais relacionadas ao trabalho em relação ao gênero. Participaram 178 universitários de diversos cursos que responderam os instrumentos de forma coletiva e presencial em sala de aula. Como medida utilizou-se duas escalas de valores relativos ao trabalho: uma sobre prioridade atribuída a metas motivacionais (alphas entre 0,81 e 0,88) e outra sobre a satisfação de tais metas (alphas entre 0,86 e 0,95). Os dados analisados, utilizando-se da técnica estatística ANOVA, demonstraram que as mulheres priorizam valores laborais de autonomia intelectual e criatividade; e priorizam, mais que os homens, segurança e ordem na vida. Não foram identificadas diferenças significativas entre gênero e satisfação dos valores laborais. Esses resultados são discutidos ressaltando-se a idéia de uma caracterização específica de gênero no mundo do trabalho, possibilitando a convivência com princípios e metas motivacionais paradoxais.
Fatores associados ao abuso de drogas em uma população clínica
Authors: Peuker Ana Carolina , Rosemberg Roberta , Cunha Silvia Mendes da , Araújo Lisiane Bizarro
Published: April 2011

Foram investigadas as possíveis relações entre consumo de drogas, expectativas positivas quanto aos efeitos do álcool e sintomatologia depressiva e ansiosa. Participaram da pesquisa 40 indivíduos, com 26 anos em média, de ambos os sexos, atendidos em um serviço psicológico. Utilizou-se o Inventário de Expectativas e Crenças Pessoais Acerca do Álcool (IECPA), o Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) e os Inventários de Beck de Ansiedade e Depressão. Constataram-se índices elevados de abuso de tabaco, álcool e observaram-se também expectativas positivas quanto aos efeitos do álcool. Tabagismo e ansiedade clinicamente significativa correlacionaram-se positivamente. Índices mais altos de expectativas positivas quanto ao consumo etílico estavam correlacionadas ao abuso de tabaco e álcool. Expectativas podem ser alteradas em programas preventivos, modificando-se padrões de consumo de risco. A associação entre sintomas psiquiátricos e uso de drogas deve ser considerada ao se estabelecerem programas preventivos e tratamentos.
Tribunal simulado: efeito da ordem das teses e do antecedente do réu
Authors: Pilati Ronaldo , Silvino Alexandre Magno Dias , Miura Marco Akira , Caldas Lucas Soares
Published: April 2011

Dois estudos experimentais de tribunal simulado tiveram como objetivo avaliar o efeito do antecedente criminal do réu e da ordem de apresentação das teses de acusação e defesa na deliberação de jurados. No primeiro foi realizado um delineamento fatorial 2 (ordem das teses) X 2 (perfil do réu) do qual participaram 123 estudantes, que assistiram a um julgamento simulado gravado em vídeo. Os resultados indicaram que houve tendência de condenação e que a ordem e o perfil não influenciam na deliberação, mas que o desempenho dos atores do vídeo exerceu efeito significativo na deliberação. No segundo estudo o caso foi apresentado de forma textual, sem apoio do vídeo. Apenas a variável perfil fez parte do delineamento e participaram do estudo 54 estudantes. Os resultados indicaram que o perfil não exerceu efeito na deliberação, mas a amostra tendeu a absolver o réu. Processos sócio-cognitivos precisam ser melhor investigados em estudos futuros.

Authors: Martins Lara Barros , Costa Nina Rosa do Amaral , Rossetti-Ferreira Maria Clotilde
Published: April 2011

Este artigo objetiva caracterizar os principais atores envolvidos em um programa de Acolhimento Familiar e os acolhimentos realizados. Esse programa efetuou 314 acolhimentos entre 1998 e 2007. Neste período, a maioria dos acolhidos eram meninos (51,7%), afrodescendentes (55,3%), de até seis anos (58,7%). As famílias acolhedoras eram constituídas por casais (70,4%), com filhos (84,1%); faixa etária entre 30 e 49 anos; bom nível de escolarização; profissões autônomas; rendas diversificadas e motivações solidárias para acolher. Com relação às famílias de origem não foram encontradas informações. Como principal causa dos acolhimentos foi citada a negligência (33,7%). Sua duração foi de um a seis meses em 46,65% dos casos. Quanto aos encaminhamentos pós-acolhimento, 34,2% das crianças foram adotadas e 33,8%, reintegradas às suas famílias. Caracterizar um programa oferece subsídios para a redefinição de práticas e auxilia na formulação de ações de intervenção em situações complexas como o acolhimento familiar.

Authors: Lipp Laura Kolberg , Martini Fernanda de Oliveira , Oliveira-Menegotto Lisiane Machado de
Published: April 2011

O presente estudo teve por objetivo investigar as expectativas maternas em relação ao desenvolvimento e escolarização do filho com síndrome de Down, a partir de uma perspectiva psicanalítica. Foi realizado um estudo qualitativo, por meio de entrevistas, que foram gravadas, transcritas e posteriormente analisadas, a partir de análise qualitativa de conteúdo. Participaram do estudo 12 mães de pessoas com síndrome de Down, com idades entre dois meses e 23 anos. Os resultados revelaram que o diagnóstico de síndrome de Down gera impacto nas mães. Em decorrência disso, as mães apresentaram dificuldade de construir expectativas em relação ao desenvolvimento e escolarização. Ressalta-se a importância do apoio e acompanhamento da mãe, no que se refere ao exercício da maternidade, bem como de professores que acompanharão o aluno com síndrome de Down a partir da idade escolar.
A banalização da prescrição de psicofármacos em um ambulatório de saúde mental
Authors: Ferrazza Daniele de Andrade , Luzio Cristina Amélia , Rocha Luiz Carlos da , Sanches Raphael Rodrigues
Published: April 2011

A conjunção do desenvolvimento dos psicofármacos modernos com o amplo alcance que assumiu a ênfase preventiva em saúde mental na atualidade modificou as práticas da Psiquiatria, que deixou de ser um saber voltado exclusivamente ao tratamento da loucura para dedicar-se a medicar, através da prescrição de psicofármacos, qualquer manifestação de sofrimento psíquico. O presente trabalho problematiza esse processo atual de medicalização generalizada da população e apresenta dados de um estudo exploratório amostral que objetivou conhecer, através do exame de registros de prontuários, a trajetória dos usuários da porta de entrada do Pronto Atendimento até a prescrição de psicofármacos no âmbito de um Ambulatório de Saúde Mental de uma pequena cidade do oeste paulista. Nossos dados mostram que a maioria (65%) dos usuários já chega ao serviço sob prescrição prévia de psicofármacos e que, encaminhados à consulta psiquiátrica, praticamente todos (99%) recebem prescrição de psicofármacos.

Published: April 2011

O objetivo do trabalho foi avaliar as propriedades de barreira e a solubilidade de biofilmes obtidos a partir de amido de ervilha de alto teor de amilose em associação à goma xantana e glicerol. Soluções filmogênicas (SF) com diferentes teores de amido de ervilha (3, 4 e 5%), goma xantana (0, 0,05 e 0,1%) e glicerol (proporção glicerol-amido de 1:5 P/P) foram estudadas. As SF foram obtidas por ebulição (5 minutos), seguida de autoclavagem por 1 hora a 120 ºC e os filmes foram preparados por casting. O aumento da concentração de amido e de glicerol na composição causou aumento da espessura e da solubilidade dos filmes em água. O plastificante gerou ainda elevação dos coeficientes de permeabilidade ao vapor d'água e ao oxigênio. O aumento da concentração da goma xantana não interferiu nas propriedades estudadas. Os biofilmes obtidos a partir de amido de ervilha verde, associado ou não à goma xantana e glicerol, se comparados com filmes de amido de ervilha amarelas e outras fontes de amido, apresentaram boa barreira ao oxigênio e ao vapor d'água e baixa solubilidade em água.

Published: April 2011

A pesquisa demonstra como é o comportamento de dois materiais conhecidos comercialmente como mastic em relação às forças de cisalhamento de selantes. No mercado existem dois tipos de mastic, um da família de silicones e outro da borracha butílica. A pesquisa teve o objetivo de esclarecer junto à receita federal e ao mercado, que as propriedades dos dois tipos são muito diferentes, apesar de ambos sofrerem um processo de cura. Com o tempo há aumento das forças de coesão e adesão de ambos, o que evidencia o processo de cura.

Authors: Oliveira Marcelo F. L. de , Oliveira Márcia G. de , Leite Márcia C. A. M.
Published: April 2011

Nanocompósitos de poliamida 6 e argila organofílica claytone 40 foram preparados por intercalação por fusão, utilizando misturador de câmara interna equipado com rotores do tipo Roller. A adição de teores crescentes de claytone 40 na matriz de PA6 foi avaliada quanto ao grau de dispersão, cristalinidade, propriedades térmicas e as propriedades mecânicas. As composições obtidas foram caracterizadas por difração de raios X (DRX), calorimetria diferencial de varredura (DSC), microscopia eletrônica de varredura (MEV) e propriedades mecânicas. Os difratogramas e as micrografias sugeriram a ocorrência de formação de estruturas parcialmente esfoliadas e/ ou intercaladas, fato que foi associado com o aumento nos valores de tensão e o módulo elástico. A comparação entre os resultados de DSC e DRX das misturas revelaram alterações estruturais na cristalinidade em relação à PA6 correlacionando a cristalinidade à variação nas propriedades mecânicas.

Published: April 2011

O objetivo do estudo foi avaliar a efetividade de um programa educacional sobre tabagismo desenvolvido pelo Instituto Nacional do Câncer em adolescentes escolares de Pelotas, RS. Das 46 escolas públicas da cidade, 32 foram sorteadas aleatoriamente e, posteriormente, randomizadas em grupo controle ou intervenção. Em ambas as fases do estudo (pré e pós-intervenção), os estudantes de 7ª e 8ª série responderam a um questionário, e uma amostra de urina foi coletada para análise de cotinina. A intervenção educativa teve duração de seis meses. Os desfechos estudados foram: "auto-relato de uso de cigarros nos últimos 30 dias" e "concentração de cotinina na urina (categorizada em > 10 ng/ml e > 30 ng/ml)". A intervenção não provocou mudança na prevalência de tabagismo, tanto mensurado por auto-relato como pela concentração de cotinina. No entanto, o conhecimento dos alunos acerca dos malefícios do cigarro aumentou no grupo intervenção. Em resumo, não houve efetividade da intervenção educacional para mudanças de comportamento, mas houve melhora no conhecimento dos prejuízos do fumo.
Un aporte de Carlos Guastavino y Lima Quintana al mundo de la Nueva Canción argentina
Authors: Mansilla Silvina Luz
Published: April 2011

El artículo se refiere a la canción Hermano compuesta por el músico Carlos Guastavino sobre una poesía de Hamlet Lima Quintana. Dedicada al editor Rómulo Lagos, fue grabada por Mercedes Sosa en 1966. Incluida como pista inicial del disco de la cantante tucumana al cual le dio su nombre, la canción constituye una evidencia de la simpatía del compositor con los postulados centrales del Nuevo Cancionero argentino. El trabajo comprende una aproximación a la temática del poema, el análisis musical de la partitura, la puesta en contexto de las circunstancias de composición y difusión y la descripción de la versión grabada por Mercedes Sosa. Aplicando la noción "mundos del arte" de Howard BECKER (1982), se interpreta la red de personas ligadas a la editorial Lagos como un tejido cooperativo que funcionó con eficacia hasta mediados de la década de 1970. Un esbozo del contexto posterior, signado por la censura, permite inferir algunos factores que incidieron en el quiebre de esa red de colaboraciones. Aunque respecto de Guastavino, se habla aquí de vinculación y no de pertenencia.
Fonograma 108.077: o lundu de George W. Johnson
Authors: Palombini Carlos
Published: April 2011

Um exame do fonograma Gargalhada (pega na chaleira), cançoneta por Eduardo das Neves, expõe a origem da expressão "pegar na chaleira" e revela incongruências nos critérios de catalogação online do Instituto Moreira Salles. Provavelmente datada de 1906, a gravação aparece como um "lundu" em catálogos comerciais de 1915-1926, e as mesmas ideias musicais foram reaproveitadas em outros registros sonoros da Casa Edison comercializados entre 1913 e 1919. A música e o gargalhar que Neves reaproveita foram criados por George Washington Johnson, o primeiro astro negro da gravação mecânica. Mas enquanto o ex-escravo norte-americano se auto-ridiculariza de acordo com estereótipos brancos, o autodenominado "crioulo" encena uma sátira ao comportamento masculino das classes dominantes do Rio. Neste processo, a coon song transforma-se na antítese do gênero.
Ernesto Nazareth e a valsa da Suíte Retratos de Radamés Gnattali
Authors: Lima Luciano Chagas
Published: April 2011

Composta por Radamés Gnattali (1906-1988) em 1956 para bandolim solista, conjunto de choro e orquestra de cordas, Retratos é uma suíte em quatro movimentos onde são homenageadas algumas das mais expressivas personalidades do cenário da música popular brasileira: Pixinguinha, Ernesto Nazareth, Anacleto de Medeiros e Chiquinha Gonzaga. O que dá forma e sustenta a narrativa da obra é a ideia de que os movimentos constituem retratos musicais destes compositores. Assim, a estrutura de cada movimento foi elaborada a partir de um modelo, ou seja, de cada compositor Gnattali escolheu uma peça que serviria de roteiro para o processo criativo dos retratos. Este estudo tem como foco o segundo movimento da suíte, a valsa, observando como está relacionado ao seu respectivo modelo, a valsa Expansiva de Ernesto Nazareth (1863-1934). Para ilustrar o paralelo será apresentada uma análise mais comparativa do que formal, procurando ampliar a visão do contexto histórico com evidências musicais, concentrando-se principalmente nos elementos comuns a ambas as peças.

Spatial and temporal variation of benthic fish assemblages during the extreme drought of 1997-98 (El Niño) in the middle rio Negro, Amazonia, Brazil
Authors: Thomé-Souza Mario J. F. , Chao Ning Labbish
Published: April 2011

Spatial and temporal variation in the benthic fish composition, species richness, density and biomass were studied in the lower rio Branco and its confluence with the rio Negro during the 1997-98 dry season (September to February). Samples were taken with a 5.28 m (16-ft) otter trawl in three expeditions and at two depth strata (<7m and >7m). Five to seven trawl hauls were made randomly in each sample site per expedition. A total of 58 trawls yielded 134 species, 5,657 individuals and 22 kg total biomass. Fishes were distributed in 25 families and seven orders. Siluriformes was the most specious with 59 species, followed by Gymnotiformes (30), Characiformes (30), Perciformes (9), Clupeiformes (4), Pleuronectiformes (1) and Tetraodontiformes (1). The variation on composition, richness of species, density and biomass occurred during the dry season, from September 1997 to February 1998. Differences between depth strata were observed. Siluriformes and Gymnotiformes were more abundant at the beginning of the dry season (September) but diminished toward the end of dry season (February), whereas the Perciformes and Characiformes (mainly post-larvae and juveniles) became more abundant at the end of the dry season. The diminishing density of benthic fish communities during this extremely dry season may have been caused by predation or migration.
Systematics of Lamontichthys Miranda-Ribeiro (Siluriformes: Loricariidae), with the description of two new species
Authors: Paixão Andrea de Carvalho , Toledo-Piza Mônica
Published: April 2011

The taxonomic revision of the genus Lamontichthys Miranda-Ribeiro, based on the examination of 164 specimens of different river drainages throughout the Amazon basin, revealed the presence of six species of which two are new. Lamontichthys filamentosus occurs in the upper and middle portions of the rio Amazonas basin; L. llanero in the río Orinoco basin; L. maracaibero in the lago Maracaibo basin; and L. stibaros in the upper río Amazonas basin. Lamontichthys avacanoeiro, new species, occurs in the upper rio Tocantins basin; and L. parakana, new species, in the lower rio Tocantins basin. The new species represent a considerable extension in the so far known distribution of the genus. A parsimony analysis, including 87 osteological and external morphological characters from Lamontichthys and related taxa (total of 16), resulted in three most parsimonious trees with 194 steps (CI = 0.73 and RI = 0.78). The hypothesis of monophyly of Lamontichthys is corroborated and supported by six derived characters. Within Lamontichthys two monophyletic assemblages are recognized, one includes L. avacanoeiro and L. stibaros, the other includes L. maracaibero and the clade formed by L. filamentosus and L. llanero. The relationships of Lamontichthys parakana, a species that was not included in the phylogenetic analysis is discussed. The monophyly and relationships of the monotypic genus Pterosturisoma microps are also discussed.
Morphological development of Anchoviella vaillanti (Steindachner, 1908) (Clupeiformes: Engraulidae) larvae and early juveniles
Authors: Silva Anailza Cristina G. da , Severi William , Castro Maviael F. de
Published: April 2011

The considerable similarity in the early life stages of different fish species makes egg and larvae identification in fishery biology and ichthyoplankton surveys a difficult task. Knowledge on early larval development of morphologically similar taxa and species-rich orders, such as Clupeiformes, mainly in the Neotropical fresh waters is rather limited. The aim of the present study was to describe morphological and meristic aspects of the larvae and early juveniles of Anchoviella vaillanti, an endemic species of the São Francisco River basin in Brazil. The characterization was based on an ontogenetic series of 132 individuals (1.3-51.0 mm SL). In the larval period, body varies from elongated to very elongated and the head is small, which is typical of Clupeiformes. The finfold is present beginning in the yolk-sac stage, when larvae have a large yolk sac, until the flexion stage. Pectoral fin buds are the first to form during the preflexion stage, when dorsal- and anal-fin pterygiophores and hypural bones are first visible. The total vertebra count ranges from 36 to 39 and the myomere number ranges from 31 to 45. Complete fin formation obeys the following sequence: anal and dorsal fins during flexion stage; and pectoral, pelvic and caudal fins during postflexion stage. Despite being the only freshwater clupeiform representative in the São Francisco River, A. vaillanti may occur sympatrically with A. lepidentostole in the lower stretches of the river basin. Although early larvae characteristics of A. lepidentostole are not known, its late larvae and early juveniles may be distinguished from those of A. vaillanti, by the higher number of dorsal-fin rays (15 or 16 vs. 12 or 13 in A. vaillanti), higher total vertebra count (40 vs. 37 to 40) and shorter pre-pectoral length (14 to 16 vs. 22.8 to 28.9% SL).
Habitat simplification affects nuclear-follower foraging association among stream fishes
Authors: Teresa Fabrício Barreto , Romero Renato de Mei , Casatti Lilian , Sabino José
Published: April 2011

Nuclear-follower interaction is a particular kind of interspecific foraging association that includes a nuclear species, which dig in or inspect the bottom, and follower species, which access the food items made available by the nuclear. In this study we examined the effect of habitat structure on nuclear-follower relationship in a stream of Bodoquena Plateau, Central-West Brazil. Foraging associations were registered while snorkeling in 24 observation sessions, totaling six hours in unaltered and altered sites. Overall, 272 nuclear-follower associations were registered, having four species acting as nuclear and seven as followers. The dominant nuclear species were different in each site. Prochilodus lineatus was the main nuclear species in the altered site and Leporinus macrocephalus in the unaltered site. The richness of follower species was similar between sites, however, follower species abundance per interaction were significantly higher in the unaltered site than in the altered site. These differences seem to be a consequence of the alterations in assemblage composition and feeding behavior of the nuclear species that presumably are affected by different substrate composition and food availability between the structurally distinct areas.

Published: April 2011

The multitargeted tyrosine-kinase inhibitor sunitinib has emerged as one of the standards of care for good- and intermediate-risk metastatic renal cell carcinoma. Although generally associated with acceptable toxicity, sunitinib exhibits a novel and distinct toxicity profile that requires monitoring and management. Fatigue, diarrhea, anorexia, oral changes, hand-foot syndrome and other skin toxicity, thyroid dysfunction, myelotoxicity, and hypertension seem to be the most common and clinically relevant toxicities of sunitinib. Drug dosing and treatment duration are correlated with response to treatment and survival. Treatment recommendations for hypertension have been published but, currently, no standard guidelines exist for the management of noncardiovascular side effects. To discuss the optimal management of noncardiovascular side effects, an international, interdisciplinary panel of experts gathered in November 2009. Existing literature on incidence, severity, and underlying mechanisms of side effects as well as on potential treatment options were carefully reviewed and discussed. On the basis of these proceedings and the thorough review of the existing literature, recommendations were made for the monitoring, prevention, and treatment of the most common noncardiovascular side effects and are summarized in this review. The proactive assessment and consistent and timely management of sunitinib-related side effects are critical to ensure optimal treatment benefit by allowing appropriate drug dosing and prolonged treatment periods.
Two decades of destruction in Southeast Asia's peat swamp forests
Authors: Miettinen Jukka , Shi Chenghua , Liew Soo Chin
Published: April 2011

We used land‐cover maps and active fire detection based on satellite imagery to evaluate the rates and spatial distribution of peatland deforestation in Southeast Asia from 1990 to 2010. Over this time period, the proportion of forest cover in the peatlands of Peninsular Malaysia, Sumatra, and Borneo fell from 77% to 36%. After two decades of extensive deforestation (31 000 km2; 4.9% yr−1) strongly associated with fire activity, Sumatra has been left with just 28% of its historical forested peatlands. If peatland deforestation is allowed to continue at current rates, the Southeast Asian peat swamp forests will disappear by around 2030. This will have serious consequences for the local communities that rely on the environmental services provided by peat swamp forests, will lead to the extinction of peat swamp forest species endemic to this region, and will contribute to global carbon emissions.
Public Administration and Constitutional Power
Authors: Cutting Bruce , Kouzmin Alexander
Published: April 2011

This is the core chapter on the separation of powers within the constitutional governance structure of
the United States and how public administration fits within that structure. The triad of political powers is
identified together with the triad of jurisdictions in terms of the local, state and national government. The
subordinate role of public administration within the executive power of government is explained in contrast to the
assertions in the Blacksburg Manifesto (Wamsley, 1990a). The public administration's role in defining the public
interest is explained, where the public interest is defined in terms of the "good" to which American society is
consciously aspiring.
Power and Authority in Corporate Governance
Authors: Cutting Bruce , Kouzmin Alexander
Published: April 2011

The historical development of peoples' thinking on property is used to explore the nature and
dynamics of governance in the private corporation. It is argued that there has been a shift to a higher level of
abstract thinking on the rights of property ownership in keeping with the new age of politicism, which helps, in
turn, to identify the new emerging responsibilities of executive management. This leads to an analysis of the
shifting distribution of corporate political power between executive management and corporate boards. The
treatment of the "corporation as a person" has to evolve into thinking about large corporations as well-governed
societies akin to nation states.

Organizations in the social sphere are analysed from the triadic viewpoint. Not-for-profit organizations
are understood to be driven by inner meaning. The longevity of the Roman Catholic Church as an organization
has been supported by a well-defined triadic structure and meaning. The governance of the Church is explored in
terms of authority sphere, their cultural sphere and the participant sphere.
A sandwich anion receptor by a BODIPY dye bearing two calix[4]pyrrole units
Authors: Lv Yongjun , Xu Jian , Guo Yong , Shao Shijun
Published: April 2011

A novel dicalix[4]pyrrolyl-substituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dye I with an absorption peak at approximately 670 nm and an emission peak at about 690 nm was prepared. As an anion receptor, I displayed a red shift in absorption spectra and fluorescence quenching in varying degrees in the presence of F−, AcO−, H2PO4−, or Cl−. Compared with the parent calix[4]pyrrole, a representative anion receptor, I exhibited a stronger affinity to these anions due to the formation of a sandwich complex through multiple hydrogen-bonding interactions.

Testing the Sustainability of Growth of the LJSEX in the January 2000 to May 2010 period

In this paper we analyse the behaviour of the LJSEX, the main index of the Ljubljana Stock Exchange, in the period from January 2000 till May 2010. More precisely, we test for the presence of bubbles and antibubbles and try to determine whether or not a bubble could have been predicted (both the formation and the date of the bubble burst). Second, we also employ techniques used to model antibubbles to forecast the future behaviour of the LJSE index. Besides modelling index dynamics for the aforementioned period, we also seek to determine the factors that led to the bubble forming and later bursting. We find that the bubble could have been forecasted at least several months in advance. On the other hand, a very precise date of the crash seems harder to identify. By more closely analysing the interplay between interest rates, credit activity and the LJSEX, we conclude that there is a clear connection between decreasing interest rates, increased credit activity and the formation of a stock bubble. If there is a clear correlation between the early phase of a bubble and increased credit activity of the banking sector, the link between the end of the bubble and the restriction of credit activity is less pronounced. By fitting the extended antibubble model from (Johansen 1999a) we obtain the values of parameters that give us some indication of the future behaviour of the LJSEX. Based on these results we conclude that in the next few years we are likely to experience a period of increased volatility with no clear increasing or decreasing growth pattern.

Sorghum [Sorghum bicolor (L.) Moench] germplasm lines designated KS201 through KS234 (Reg. No. GP‐684, PI 659520 to Reg. No. GP‐717, PI 659553) were developed and released by the Kansas Agricultural Experiment Station, Manhattan, KS in 2007. The donor of the herbicide resistance gene, Tailwind, was crossed to adapted‐seed and pollinator‐parent lines. The progenies were treated with the target herbicide, and resistant individuals were repeatedly backcrossed to the adapted parents. Backcrossing was performed until the undesirable wild characteristics from the donor parent were eliminated. Lines KS201 through KS218 are R lines and restore fertility in A1 cytoplasm system; lines KS219 through KS234 are B lines and do not restore fertility in A1 cytoplasm. All lines possess a unique genetic resistance to acetolactate synthase (ALS)–inhibitor herbicide families and are useful breeding materials for the development of commercial hybrids with ALS resistance. The lines are all of combine‐harvester height and reach 50% flowering 60 to 82 d after planting at Manhattan, KS. A majority of the lines are pigmented plant types and have variable grain color and seed sizes within the range common to existing public inbreds.

‘CL151’ (Reg. No. CV‐133, PI 654463), a Clearfield (BASF, Ludwigshafen, Germany) long‐grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the Rice Research Station near Crowley, LA, and approved for release by the director of the Louisiana Agricultural Experiment Station in 2008. The population from which CL151 was derived began as a single cross of CFX‐26/RU9702128 (‘Lemont’/20001–5/3/Lemont//‘L‐202’/‘TDCN’) that was made in 2000 at the Rice Research Station. CFX‐26, which contains the gene for resistance to imazethapyr and can be used with the Clearfield rice production system, was derived via mutation breeding of the variety ‘Cypress.’ CL151 originated in 2003 as an F2:3 line selected based on agronomic characteristics. Testing in the Clearfield preliminary yield trials in 2004 indicated high yield potential and favorable agronomic characteristics. In 2005 and 2006, CL151 was tested in 41 statewide yield performance trials, along with two high‐yielding, Clearfield check cultivars, ‘CL131’ and ‘CL161.’ Rice‐grain yield of CL151 was 8.3 Mg ha−1 compared with 7.5 and 7.6 Mg ha−1 for CL131 and CL161, respectively. CL151 has higher seedling vigor than CL131 or CL161. Plant height for CL151 was 94 cm compared with 84 and 99 cm for CL131 and CL161, respectively. Both CL151 and CL131 reached 50% heading in 81 d, and CL161 reached 50% heading in 84 d. CL151 has a semierect flag leaf, and the leaves are dark green and display an intermediate leaf angle. The lemma and palea are straw‐colored and glabrous, and the apiculus is colorless as the grain approaches harvest maturity.

R99–1613F (Reg. No. GP‐372, PI 659987), R01–2731F (Reg. No. GP‐374, PI 659989), and R01–3474F (Reg. No. GP‐373, PI 659988) soybean [Glycine max (L.) Merr.] were developed by the Arkansas Agricultural Experiment Station, Fayetteville, AR and were released as high‐yielding conventional germplasm lines with 50% diverse pedigrees. R99–1613F is an F4 plant selection from the cross between ‘NK RA 452’ and PI 290126B. It is an indeterminate maturity group (MG) IV line with a yield potential similar to that of the popular Roundup Ready cultivar ‘AG4403’. R01–2731F is a determinate MG VI line derived from the cross ‘Caviness’ × PI 592947. Yield potential of R01–2731F is similar to or greater than conventional MG VI cultivar ‘Dillon’. R01–3474F was derived from Caviness × PI 594208. It is a determinate MG V line with a yield potential similar to that of the high‐yielding conventional cultivar ‘5601T’. These germplasm lines can be used as elite parents to improve yield and to enhance genetic diversity.

‘Acala 1517–09R’ (Reg. No. CV‐127, PI 659506) was developed by the New Mexico Agricultural Experiment Station and released in 2010 as a new Roundup Ready Acala cotton (Gossypium hirsutum L.) cultivar. This new cultivar was a single plant selection derived from a backcross BC3F2 between a Roundup Ready gene donor and ‘Acala 1517–99’ as the recurrent parent, and it possesses the superior fiber quality of Acala cotton and high yield potential. Acala 1517–09R was tested in 11 replicated field trials in New Mexico from 2004 to 2007, seven field tests in other southwest locations (eastern Arizona and the High Plains of Texas) in 2004–2007, and seven locations outside of the southwest arid region of the Cotton Belt in 2005. Acala 1517–09R had similar or higher (averaged 15.6% higher) lint yield than the standard, Acala 1517–99, across all the environments tested in New Mexico. Its yield was similar to or higher than that of Acala 1517–99, except for one test outside of the southwest. On average, Acala 1517–09R had longer and finer fibers than Acala 1517–99, with a slightly higher lint percentage but reduced boll weight and fiber strength. Acala 1517–09R is best adapted to the southwest arid region of the Cotton Belt, where the traditional Acala 1517 cultivars have been grown.

F1024 (Reg. No. GP‐272, PI 658654) sugarbeet (Beta vulgaris L.) germplasm with resistance to sugarbeet root maggot (Tetanops myopaeformis von Röder) was released by the USDA‐ARS and the North Dakota Agricultural Experiment Station, North Dakota State University, Fargo, ND on 15 Dec. 2009. F1024 was selected from a population formed by crossing F1016, a germplasm line resistant to root maggot, with a breeding line resistant to Cercospora leaf spot (CLS; caused by Cercospora beticola Sacc.). The population was subjected to three cycles of mass selection for resistance to root maggot followed by three cycles of selection among half‐sib families. Under natural root maggot infestations, F1024 had a damage rating of 2.1 (on a scale of 1 to 9, where 0 = no maggot feeding, and 9 = >75% of root surface with feeding scars), compared with an average of 6.1 for two susceptible commercial hybrids. In a 2009 CLS evaluation, F1024 had a significantly lower disease rating than the susceptible check, and the difference between F1024 and the resistant checks was not significant. The performance of testcross hybrids between the component half‐sib families of F1024 and a susceptible cytoplasmic‐male‐sterile line provided additional validation of the potential of root maggot–resistant hybrids in areas where root maggot is a perpetual threat.

Published: April 2011

‘Avalanche’ (Reg. No. CV‐298, PI 656378) is a new navy bean cultivar developed by the dry‐bean breeding program at North Dakota State University and released by the North Dakota Agricultural Experiment Station. Avalanche is a medium‐early maturing, high‐yielding navy bean, with commercially acceptable seed size, shape, and appearance. Avalanche is erect (Type IIb, upright short vine) and has good lodging resistance. Avalanche exhibits good and synchronous plant drydown before harvest. Maturity is 5 and 2 d earlier than ‘Vista’ and ‘Mayflower’, respectively. Multilocation testing showed that Avalanche outyielded Vista, Mayflower, and ‘Norstar’ by 10, 8, and 11%, respectively. Avalanche is resistant to Bean common mosaic virus and is moderately resistant to the races of bean rust [caused by Uromyces appendiculatus (Pers.:Pers.) Unger] usually found in the region, with the exception of the new race (20–3). In addition, Avalanche is tolerant to soil Zn deficiency, which is an abiotic factor that severely affects navy and black beans. Canning tests showed that Avalanche was similar to Vista in terms of visual appearance and quality. Given its competitive seed yield, agronomic, and processing attributes, Avalanche has the potential to become one of the most important cultivars not only for the northern Great Plains but also for other bean‐growing regions in North America.
Registration of MD 9ne and MD 25 High‐Fiber‐Quality Germplasm Lines of Cotton
Authors: Meredith W. R. , Nokes W. S.
Published: April 2011

MD 9ne (Reg. No. GP‐928, PI 659507) and MD 25 (Reg. No. GP‐929, PI 659508) are noncommercial breeding lines of cotton (Gossypium hirsutum L.) released by the USDA‐ARS at Stoneville, MS. One parent of MD 9ne was a strain of ‘MD51ne’ (PI 566941) that had high‐fiber‐quality genes introduced from the species polycross. The other parent was MD 15 (PI 642769). The parents of MD 25 were MD 9ne and a noncommercial Sure‐Grow strain. MD 9ne was grown at eight locations in the 2004 Regional High Quality (RHQ) test. Its yield was near average for the test. Its strength as measured by a stelometer instrument and it yarn tenacity were significantly greater than those of any other entry. Its uniformity was the highest of the 19 strains tested. MD 25 was evaluated in the 2008 RHQ test with 19 other entries. The yield of MD 25 was about average for the test. MD 25's yarn tenacity was 146 mN tex−1, second to TAM 182–34ELS with 154 mN tex−1, but MD 25's lint yield was 24.3% greater. MD 25's uniformity index and fiber length were above the test average. Removing MD 25 from a 20‐entry regression analysis suggested that it had a different yield/yarn‐tenacity relationship than the other 19 entries. MD 9ne is nectariless 2(ne1
, ne2
), and MD 25 segregates for the nectariless trait, which confers resistance to a number of pests, principally the tarnished plant bug (Lygus lineolarus Palisot deBeauvois). In 2008 this insect caused as much loss to the cotton crop in the United States as all other cotton insects combined.
Registration of the MN98550–5/MN99394–1 Wheat Recombinant Inbred Mapping Population
Authors: Tsilo Toi J. , Linkert Gary L. , Hareland Gary A. , Anderson James A.
Published: April 2011

A mapping population was developed from the two hard red spring wheat (Triticum aestivum L.) breeding lines MN98550–5 (PI 660540 MAP) and MN99394–1 (PI 660541 MAP) at the University of Minnesota. This population, MN98550‐5/MN99394‐1 (Reg. No. MP‐4, NSL 472873 MAP), comprises 139 F6:8 recombinant inbred lines (RILs). The primary objective of developing this mapping population was to identify the chromosome regions that influence end‐use quality traits in hard red spring wheat lines that are adapted to the Upper Midwest region of the USA. The population was genotyped with diversity array technology and simple sequence repeat markers, and the genetic map was composed of 531 marker loci covering all 21 chromosomes of wheat. Forty‐three quantitative trait loci (QTL) influenced dough‐mixing strength and bread‐making properties. This population also segregated for several important traits, including resistance to fungal diseases (leaf rust, caused by Puccinia triticina f. sp. tritici; and stem rust, caused by P. graminis f. sp. tritici), kernel characteristics, and agronomic traits, and their QTL and closely linked markers were identified. The information obtained from QTL analysis was useful in selecting the best RILs as parents in our breeding program.

Improvement of fiber quality is essential if cotton farmers in the United States are to compete in the world market. A high‐quality cotton (Gossypium hirsutum L.) germplasm designated as TTU 0782 (Reg. No. GP‐930, PI 659504) was developed and released by the Department of Soil Science, Texas Tech University, on 25 May 2010. TTU 0782 was derived from the cross of TTU 202‐1107B with ‘Acala 1517‐95’, and it possesses highly favorable fiber length, high fiber‐bundle strength, and a desirable fiber‐length uniformity index as determined by high‐volume‐instrument testing. In addition, TTU 0782 exhibits low short‐fiber content, a high maturity ratio, and low nep counts as determined by the Advanced Fiber Information System. Spinning tests indicate that TTU 0782 had improved yarn tenacity and fewer thin and thick places, fewer neps, and less hairiness of yarn when compared with previously registered germplasm lines from Texas Tech University and with ‘FiberMax 958’.
