The draft genome of Ciona intestinalis: Insights into chordate and vertebrate origins

The first chordates appear in the fossil record at the time of the Cambrian explosion, nearly 550 million years ago. The modern ascidian tadpole represents a plausible approximation to these ancestral chordates. To illuminate the origins of chordate and vertebrates, we generated a draft of the protein-coding portion of the genome of the most studied ascidian, Ciona intestinalis. The Ciona genome contains similar to16,000 protein-coding genes, similar to the number in other invertebrates, but only half that found in vertebrates. Vertebrate gene families are typically found in simplified form in Ciona, suggesting that ascidians contain the basic ancestral complement of genes involved in cell signaling and development. The ascidian genome has also acquired a number of lineage-specific innovations, including a group of genes engaged in cellulose metabolism that are related to those in bacteria and fungi.

Infusing the use of seasonal climate forecasting into crop management practice in North East Australia using discussion support software

Seasonal climate forecasting offers potential for improving management of crop production risks in the cropping systems of NE Australia. But how is this capability best connected to management practice? Over the past decade, we have pursued participative systems approaches involving simulation-aided discussion with advisers and decision-makers. This has led to the development of discussion support software as a key vehicle for facilitating infusion of forecasting capability into practice. In this paper, we set out the basis of our approach, its implementation and preliminary evaluation. We outline the development of the discussion support software Whopper Cropper, which was designed for, and in close consultation with, public and private advisers. Whopper Cropper consists of a database of simulation output and a graphical user interface to generate analyses of risks associated with crop management options. The charts produced provide conversation pieces for advisers to use with their farmer clients in relation to the significant decisions they face. An example application, detail of the software development process and an initial survey of user needs are presented. We suggest that discussion support software is about moving beyond traditional notions of supply-driven decision support systems. Discussion support software is largely demand-driven and can compliment participatory action research programs by providing cost-effective general delivery of simulation-aided discussions about relevant management actions. The critical role of farm management advisers and dialogue among key players is highlighted. We argue that the discussion support concept, as exemplified by the software tool Whopper Cropper and the group processes surrounding it, provides an effective means to infuse innovations, like seasonal climate forecasting, into farming practice.

Communism and Carnival: Ralph de Boissieres Crown Jewel and its Australian Context

The Australasian Book Society (ABS) was established in Melbourne in 1952 by a small group ofleft-leaning writers, unionists and literary supporters. It was inspired in part by the success of Frank Hardy's scandalous novel of Labar betrayal, Power Without Glory, which in 1950 had been published independently - and printed secretly - outside the commercial publishing networks. Many of those involved were communists but although the ABS came to operate in accord ,..rith Communist Party cultural politics it was never Simply a Party front nor did it publish only communist writers or communist texts. For the most part it operated under a broader notion of 'progressive' , nationalist or democratic literature.

Exploring the role of market learning capability in competitive strategy

It has been argued that a firm's capacity to learn from its market is a source of both innovation and competitive advantage. However, past research has failed to conceptualize market-focused learning activity as a capability having the potential to contribute to competitive advantage. Prior innovation research has been biased toward technological innovation. However, there is evidence to suggest that both technological and non-technological innovations contribute to competitive advantage reflecting the need for a broader conceptualization of the innovation construct. Past research has also overlooked the critical role of entrepreneurship in the capability building process. Competitive advantage has been predominantly measured in terms of financial indicators of performance. In general, the literature reflects the need for comprehensive measures of organizational innovation and competitive advantage. This paper examines the role of market-focused learning capability in organizational innovation-based competitive strategy. The paper contributes to the strategic marketing theory by developing and refining measures of entrepreneurship, market-focused learning capability, organizational innovation and sustained competitive advantage, testing relationships among these constructs.

A genomewide survey of developmentally relevant genes in Ciona intestinalis - V. Genes for receptor tyrosine kinase pathway and Notch signaling pathway

In the present survey, we identified most of the genes involved in the receptor tyrosine kinase (RTK), mitogen activated protein kinase (MAPK) and Notch signaling pathways in the draft genome sequence of Ciona intestinalis, a basal chordate. Compared to vertebrates, most of the genes found in the Ciona genome had fewer paralogues, although several genes including ephrin, Eph and fringe appeared to have multiplied or duplicated independently in the ascidian genome. In contrast, some genes including kit/flt, PDGF and Trk receptor tyrosine kinases were not found in the present survey, suggesting that these genes are innovations in the vertebrate lineage or lost in the ascidian lineage. The gene set identified in the present analysis provides an insight into genes for the RTK, MAPK and Notch signaling pathways in the ancient chordate genome and thereby how chordates evolved these signaling pathway.

Innovation in Queensland firms: implications for the smart State

The challenges in the business environment are forcing Australian firms to be innovative in all their efforts to serve customers. Reflecting this need there have been several innovation policy statements both at Federal and State government level aimed at encouraging innovation in Australian industry. In particular, the innovation policy statement launched by the Queensland government in the year 2000 primarily intends building a Sman State through innovation. During the last few decades the Australian government policy on innovation has emphasized support for industry R&D. However industry stakeholders demand a more firm-focused policy of innovation. Government efforts in this direction have been hindered by a lack of a consistent body of knowledge on innovation at the firm level. In particular the Australian literature focusing on firm level antecedents of innovation is limited and fragmented. This study examines the role of learning capabilities in innovation and competitive advantage. Based on a survey of manufacturing firms in Queensland the study finds that both technological and non·technological innovations lead to competitive advantage. The findings contribute to the theory competitive advantage and firm level antecedents of innovation. Implications for firm level innovation strategies and behaviour are discussed. In addition, the findings have important implications for Queensland government's current initiatives to build a Smart State through innovation.

Printed advice on initiating and maintaining breastfeeding in mid-20th-century Queensland

This article, which is part of a larger historical study of infant-feeding advice received by mothers in Queensland, Australia, identifies and examines print materials that were used by mothers, or that influenced other texts, during the postwar period from 1945 to 1965. The texts are described within the context of their environmental influences and the medical knowledge and research of the time to assess what effect, if any, these latter materials had on the established system of infant-feeding advice. Two innovations that were employed are the use of interviews to identify the most-used texts and the comparison of popular advice books with medical journal material.

Read the whole thing: Journalism, weblogs and the re-mediation of the war in Iraq

This paper examines a particular form of online activity-weblogging, and how it has allowed for specific new forms of popular political communication in the context of the Second Gulf War. After describing the basics of weblogging, the paper discusses Western media coverage of the war and then shows how 'warbloggers' positioned themselves vis-à-vis media coverage and propaganda, creating commentaries that frequently combined media and political criticism. While bloggers of every political hue offered a range of perspectives and personal styles, some general tendencies are evident in warblogging discourse. The piece ends by questioning the significance of warblogging in terms of its potential contribution to democratic communication.

O combate ?? viol??ncia contra a mulher: a luta entre antigos valores e novos padr??es de pol??ticas p??blicas

O caso relata uma situa????o de viol??ncia dom??stica vivenciada por uma mulher negra e os obst??culos por ela enfrentados para denunciar o agressor e fazer valer seus direitos. Mostra a contradi????o entre normas e sua efetiva aplica????o, quando o comportamento de agentes p??blicos ainda conserva padr??es e valores de um Estado autorit??rio, patriarcal e escravocrata. O caso ?? fict??cio, mas espelha situa????es reais coletadas em documentos e relat??rios da Ouvidoria da Secretaria de Pol??ticas para as Mulheres- SPM/PR. O estudo suscita discuss??es sobre a dimens??o ??tica da atividade de agentes p??blicos de um Estado democr??tico, englobando quest??es referentes aos direitos humanos, direitos e deveres do Estado e da sociedade, o papel da transpar??ncia, do controle social e da responsabiliza????o por resultados (accountability) etc. Pode ser aplicado em cursos sobre ??tica e servi??o p??blico, pol??ticas p??blicas de g??nero e ra??a e atendimento ao cidad??o

Carreiras p??blicas em uma ordem democr??tica: entre os modelos burocr??tico e gerencial

Refletindo sobre modelo de carreira mais adequado para a Administra????o P??blica nesta era de economia globalizada e de maiores exig??ncias de efici??ncia e flexibilidade na gest??o dos aparatos governamentais, questiona-se aqui a id??ia de que o modelo burocr??tico deva ser substitu??do pelo modelo gerencial. Considerando essa id??ia apenas parcialmente verdadeira, nossa argumenta????o vai na seguinte dire????o: como a burocracia ?? a forma espec??fica de organiza????o do aparato administrativo do Estado de Direito, este modelo n??o pode ser rejeitado, sob pena de comprometimento desse Estado. Mas ele precisa ser flexibilizado, superando e reduzindo o formalismo excessivo e a rigidez que sua realiza????o hist??rica possa ter gerado nos diferentes pa??ses. Igualmente, deve ser aperfei??oado em seus mecanismos de controle, at?? como condi????o para sua manuten????o eficaz nos governos democr??ticos contempor??neos.

O t??nel no fim da luz: a privatiza????o do setor el??trico em Mato Grosso

Este artigo tem por objetivo analisar a forma????o de consensos sociais e pol??ticos para a reforma do Estado e de seu aparelho em n??vel estadual, conforme a governabilidade democr??tica. Optou-se por uma pesquisa sobre a privatiza????o das Centrais El??tricas Mato- Grossenses S.A. (Cemat), considerada representativa tanto da reforma empreendida pelo Estado de Mato Grosso quanto das dificuldades do setor el??trico em n??vel nacional. O referencial metodol??gico dessa pesquisa ?? composto de um problema e de quatro hip??teses de trabalho. Trata-se de estudo de caso da esp??cie ???provas de plausibilidade???, em que, por uma aplica????o iterativa, apresenta-se uma proposi????o te??rica inicial e, em seguida, as conclus??es da pesquisa s??o comparadas, o que permite sua revis??o e compara????o. Para tanto, descrevem-se a privatiza????o da Cemat e os problemas da desestatiza????o do setor el??trico brasileiro no seu conjunto. Por fim, na conclus??o, verifica-se a validade das hip??teses e fazem-se algumas considera????es finais sobre a pesquisa.

Reforma do setor p??blico e participa????o sindical: o caso do sistema de pens??o italiano

O paper estuda o caso da recente reforma da Previd??ncia na It??lia, ilustrando a possibilidade de uma participa????o positiva dos sindicatos ??? tradicionalmente contr??rios ??s reformas ??? no processo de transforma????o do setor p??blico. Ap??s uma revis??o do sistema previdenci??rio italiano, altamente fragmentado e particularista na opini??o dos autores, e o apontamento de suas principais defici??ncias, o estudo concentra-se na an??lise de tr??s propostas de reforma ligadas aos governos de Amato (1992-93), Berlusconi (1994) e Dini (1995), respectivamente. O texto aborda tanto as propostas concretas de mudan??a, trazendo contribui????es sobre uma variedade consider??vel de medidas, seu impacto e aceita????o sociais e por categoria, como os objetivos visados e o processo pol??tico relacionado ?? sua discuss??o e tramita????o. Uma preocupa????o constante dos autores ?? a correla????o entre a postura e a participa????o dos sindicatos em mat??ria de reforma previdenci??ria, por um lado, e o avan??o das propostas governamentais, por outro. Segundo o estudo, a ampla participa????o da for??a sindical na negocia????o do projeto de reforma previdenci??ria do governo Dini representou um fator decisivo para sua aprova????o e implementa????o bem-sucedidas. Ao mesmo tempo, a delibera????o democr??tica para concilia????o de prefer??ncias e interesses (m??ltiplos no caso de assuntos norteados pela dicotomia bem comum/interesse particular) ??? objeto da ??ltima sess??o do estudo ??? ?? vista como uma forma de ampliar a participa????o sindical al??m das lideran??as, passando a incluir os rank-and-file trabalhadores, um procedimento que traz, igualmente, a for??a de uma decis??o majorit??ria. A an??lise da reforma da Previd??ncia italiana ?? ilustrada no paper com tabelas que trazem e comparam dados referentes ?? contribui????o previdenci??ria, ??s categorias de beneficiados e ??s diferentes propostas de reforma formuladas por sucessivos governos italianos.

Reforma judici??ria e democratiza????o na Am??rica Latina

Este texto reflete a necessidade de uma reforma profunda nos sistemas judici??rios nos pa??ses da Am??rica Latina. O autor enumera os mais consider??veis eventos pol??ticos ocorridos na regi??o ap??s a d??cada de 60, principalmente durante o per??odo dos governos militares, com ??nfase nos modelos judici??rios prevalecentes ??? comumente dependentes, manipulados e fr??geis ??? bem como nos problemas enfrentados pelos ju??zes e serventu??rios da justi??a em muitos pa??ses. Ele tamb??m descreve v??rios movimentos pela reforma legal observados em dois diferentes momentos ??? do fim da d??cada de 60 e come??o da de 70, e depois, durante a d??cada de 80, comparando seus sucessos e fracassos e enumerando uma quantidade de seguidores nacionais e internacionais. Finalmente, o leitor deparar-se-?? com uma an??lise das mudan??as econ??micas e pol??ticas que t??m incentivado esta nova preocupa????o por justi??a e pela reforma das institui????es legais, dentre outras, na Am??rica Latina, assim como as dificuldades que esse movimento deve enfrentar no sentido de alcan??ar um Estado descentralizado, eficiente e democr??tico.

A reforma do Estado, a emerg??ncia da descentraliza????o e as pol??ticas ambientais

No contexto da reforma do Estado brasileiro, a descentraliza????o das compet??ncias pol??ticas e administrativas na arena ambiental tem se mostrado um processo din??mico. Muitas inst??ncias locais j?? respondem pela quest??o ambiental. No entanto, isso n??o significa mais compet??ncia administrativa, sustentabilidade institucional, tampouco participa????o democr??tica. Dois casos de pol??tica ambiental s??o retratados no texto: o licenciamento industrial pelos munic??pios brasileiros e o a gest??o florestal pelo Estado do Mato Grosso. A descentraliza????o do licenciamento ambiental para o ??mbito municipal ainda parece fr??gil em munic??pios menores, em um processo que parece ser induzido pelo Estado e n??o pelo controle social local. Em rela????o ?? pol??tica florestal, o caso do Mato Grosso ?? emblem??tico. Ele mostra que a coopera????o com o poder p??blico federal e, em determinados momentos, sua coordena????o s??o de suma import??ncia para que as pol??ticas p??blicas ambientais n??o fiquem ?? merc?? de governos estaduais, que podem envies??-las em favor do ???desenvolvimentismo???, nem percam a legitimidade adiante da fragilidade financeira e institucional dos ??rg??os ambientais locais.

O plano plurianual: resultados da mais recente reforma do planejamento e or??amento no Brasil

O artigo visa apresentar o debate acerca das transforma????es oriundas da ??ltima reforma do planejamento e or??amento no Brasil, a qual introduziu o novo desenho do Plano Plurianual (PPA). Inicialmente, os princ??pios do modelo de or??amento por resultados ou desempenho que balizaram a formula????o do novo PPA s??o discutidos. Com base nos planos de gest??o das experi??ncias recentes do Plano e na proposta do pr??ximo PPA (2008-2011), s??o apresentadas as inova????es da configura????o do processo or??ament??rio no pa??s. Por fim, o artigo aborda os avan??os e restri????es da implementa????o do novo desenho do PPA e conclui que, apesar de formalmente institu??dos, os instrumentos do or??amento por resultados n??o atingem a finalidade prec??pua do modelo: melhoria da efetividade e efici??ncia nos gastos p??blicos.
