What can we learn from the Hwang and Sudbo affairs?

* The recent publication, in prestigious scientific journals, of two major studies that were subsequently shown to contain fabricated data may compel reviewers and editors to adopt a more rigorous policy in accepting articles for publication. * The current manner of peer reviewing research articles provides no assurance that the proffered work is not the result of fraud. * The present guidelines for contributors in large team investigations may need to be updated to avoid giving credit to co-authors who may have made little, if any, contribution to the work.

Silencing of the ACC synthase gene ACACS2 causes delayed flowering in pineapple [Ananas comosus (L.) Merr.]

Flowering is a crucial developmental stage in the plant life cycle. A number of different factors, from environmental to chemical, can trigger flowering. In pineapple, and other bromeliads, it has been proposed that flowering is triggered by a small burst of ethylene production in the meristem in response to environmental cues. A 1-amino-cyclopropane-1-carboxylate synthase (ACC synthase) gene has been cloned from pineapple (ACACS2), which is induced in the meristem under the same environmental conditions that induce flowering. Two transgenic pineapple lines have been produced containing co-suppression constructs designed to down-regulate the expression of the ACACS2 gene. Northern analysis revealed that the ACACS2 gene was silenced in a number of transgenic plants in both lines. Southern hybridization revealed clear differences in the methylation status of silenced versus non-silenced plants by the inability of a methylation-sensitive enzyme to digest within the ACACS2 DNA extracted from silenced plants, indicating that methylation is the cause of the observed co-suppression of the ACACS2 gene. Flowering characteristics of the transgenic plants were studied under field conditions in South East Queensland, Australia. Flowering dynamics studies revealed significant differences in flowering behaviour, with transgenic plants exhibiting silencing showing a marked delay in flowering when compared with non-silenced transgenic plants and control non-transformed plants. It is argued that the ACACS2 gene is one of the key contributors towards triggering 'natural flowering' in mature pineapples under commercial field conditions.

Toxinology in Australia's colonial era: A chronology and perspective of human envenomation in 19th century Australia

The medical management of those envenomed by snakes, spiders and poisonous fish in Australia featured extensively in the writings 19th century doctors, expeditioners and anthropologists. Against the background of this introduced medical doctrine there already existed an extensive tradition of Aboriginal medical lore; techniques of heat treatment, suction, incision and the application of plant-derived pharmacological substances featured extensively in the management of envenomed victims. The application of a hair-string or grass-string ligature, suctioning of the bite-site and incision were practised in a variety of combinations. Such evolved independently of and pre-dated such practices, which were promoted extensively by immigrant European doctors in the late 19th century. Pacific scientific toxinology began in the 17th century with Don Diego de Prado y Tovar's 1606 account of ciguatera. By the end of the 19th century more than 30 papers and books had defined the natural history of Australian elapid poisoning. The medical management of snakebite in Australia was the focus of great controversy from 1860 to 1900. Dogmatic claims of the supposed antidote efficacy of intravenous ammonia by Professor G.B. Halford, and that of strychnine by Dr. Augustus Mueller, claimed mainstream medical attention. This era of potential iatrogenic disaster and dogma was brought to a conclusion by the objective experiments of Joseph Lauterer and Thomas Lane Bancroft in 1890 in Brisbane; and by those of C.J. Martin (from 1893) and Frank Tidswell (from 1898), both of Sydney. The modern era of Australian toxinology developed as a direct consequence of Calmette's discovery, in Paris in 1894, of immune serum, which was protective against snakebite. We review the key contributors and discoveries of toxinology in colonial Australia.

Bioerosion Research Before and After 1996 - A Discussion of What Has Changed Since the First International Bioerosion Workshop

The First International Bioerosion Workshop held in 1996 provided a forum for an increasing interest in bioerosion research and helped foster convivial relations among researchers in this specialization. The current trend in bioerosion publishing is positive and will be aided with consolidated efforts to attract both new recruits and grant awards. Contributors of the Fourth IBW in Prague decided to hold the next meeting in Erlangen, Germany.

RELAÇÕES ENTRE CARACTERÍSTICAS DOS INTEGRANTES DE EQUIPES, COMPETÊNCIAS COLETIVAS E DESEMPENHO COLETIVO

As inovações tecnológicas e as mudanças na forma de trabalho tornaram as equipes peças fundamentais no desempenho das organizações e no aprimoramento individual. A pesquisa teórica identifica que o conhecimento das características das equipes e de seus membros proporciona desempenho, desenvolvimento organizacional, determina as interações sociais e a maneira como serão realizadas as tarefas. O estudo tem por questão investigativa analisar as relações entre características dos integrantes de equipes que incluem as características sociodemográficas, competências individuais, tipos psicológicos, com as competências coletivas e o desempenho coletivo. O contexto da pesquisa é um curso de tecnologia em gastronomia de uma universidade privada, uma amostra de 131 alunos, dez equipes do quarto e onze do segundo semestres em atividades práticas no Laboratório de Alimentos. Trata-se de uma pesquisa descritiva que emprega o método de correlação para os dados quantitativos, como competências individuais e coletivas e notas acadêmicas de desempenho coletivo, além de interpretações qualitativas por observação em doze encontros das equipes para trabalhos coletivos e uma análise quali-quantitativa dos dados. O estudo evidencia ausência de correlação entre as variáveis nas equipes de 2º semestre justificada por serem equipes bastante jovens e em fase de desenvolvimento acadêmico e profissional. Na turma do 4º semestre, o coeficiente de Pearson indica correlação significativa e comprova que as características dos integrantes influenciam positivamente nas competências coletivas e resultam em melhores desempenhos coletivos. Qualitativamente, as melhores equipes são gerenciadas por uma liderança feminina adulta que coordena as tarefas e os membros são contribuintes e colaboradores enquanto o líder é comunicador e desafiador. Desenvolvem um ritmo de trabalho dinâmico com forte presença da comunicação, tomada de decisões rápidas e criativas e atingem metas diferenciadas em gastronomia. Apesar dos resultados não poderem ser generalizados pelo fato da pesquisa ter sido realizada em apenas uma universidade e envolvendo 21 equipes, os conceitos teóricos o são e podem ser testados em outras realidades.

ANÁLISE DA INFORMALIDADE: uso de crédito e crescimento perante a pesquisa da Ecinf

Este trabalho procura entender um pouco mais e discutir, partindo dos dados disponíveis do Instituto Brasileiro de Geografia e Estatística (IBGE), através de sua pesquisa de economia informal urbana (ECINF) gerada em 2003 (ultima disponível), aspectos ligados à informalidade, crescimento e uso do crédito. Procura explorar, neste contexto, aspectos relevantes ao crescimento e continuidade da micro e pequena empresa. Para atingir este objetivo, procura-se entender inicialmente conceitos sobre estes aspectos (informalidade, crescimento e uso de crédito) e suas características, e através de dados secundários e com o uso de software estatístico, procurar entender as suas relações, através de ANOVA e regressões, bem como optimal scaling contribuindo para o conhecimento deste cenário. Os dados levantandos e comparados com a teoria apontam as relações entre empregador e trabalhador por conta própria indicando dos fatores adotados no estudo quais mais contribuem e os que indicam pouca contribuição dentro deste contexto. Em conclusões acena para uma tendência onde o individamento através do uso de crédito tende a gerar um maior crescimento até um determinado ponto e a partir desta inflecção tende a dificultar a atividade bem como acena dificultar a formalização.(AU)

An Autonomic Framework for Mobile Cloud Computing

This thesis presents the formal definition of a novel Mobile Cloud Computing (MCC) extension of the Networked Autonomic Machine (NAM) framework, a general-purpose conceptual tool which describes large-scale distributed autonomic systems. The introduction of autonomic policies in the MCC paradigm has proved to be an effective technique to increase the robustness and flexibility of MCC systems. In particular, autonomic policies based on continuous resource and connectivity monitoring help automate context-aware decisions for computation offloading. We have also provided NAM with a formalization in terms of a transformational operational semantics in order to fill the gap between its existing Java implementation NAM4J and its conceptual definition. Moreover, we have extended NAM4J by adding several components with the purpose of managing large scale autonomic distributed environments. In particular, the middleware allows for the implementation of peer-to-peer (P2P) networks of NAM nodes. Moreover, NAM mobility actions have been implemented to enable the migration of code, execution state and data. Within NAM4J, we have designed and developed a component, denoted as context bus, which is particularly useful in collaborative applications in that, if replicated on each peer, it instantiates a virtual shared channel allowing nodes to notify and get notified about context events. Regarding the autonomic policies management, we have provided NAM4J with a rule engine, whose purpose is to allow a system to autonomously determine when offloading is convenient. We have also provided NAM4J with trust and reputation management mechanisms to make the middleware suitable for applications in which such aspects are of great interest. To this purpose, we have designed and implemented a distributed framework, denoted as DARTSense, where no central server is required, as reputation values are stored and updated by participants in a subjective fashion. We have also investigated the literature regarding MCC systems. The analysis pointed out that all MCC models focus on mobile devices, and consider the Cloud as a system with unlimited resources. To contribute in filling this gap, we defined a modeling and simulation framework for the design and analysis of MCC systems, encompassing both their sides. We have also implemented a modular and reusable simulator of the model. We have applied the NAM principles to two different application scenarios. First, we have defined a hybrid P2P/cloud approach where components and protocols are autonomically configured according to specific target goals, such as cost-effectiveness, reliability and availability. Merging P2P and cloud paradigms brings together the advantages of both: high availability, provided by the Cloud presence, and low cost, by exploiting inexpensive peers resources. As an example, we have shown how the proposed approach can be used to design NAM-based collaborative storage systems based on an autonomic policy to decide how to distribute data chunks among peers and Cloud, according to cost minimization and data availability goals. As a second application, we have defined an autonomic architecture for decentralized urban participatory sensing (UPS) which bridges sensor networks and mobile systems to improve effectiveness and efficiency. The developed application allows users to retrieve and publish different types of sensed information by using the features provided by NAM4J's context bus. Trust and reputation is managed through the application of DARTSense mechanisms. Also, the application includes an autonomic policy that detects areas characterized by few contributors, and tries to recruit new providers by migrating code necessary to sensing, through NAM mobility actions.

MARKETING E CRÍTICA PROFÉTICA NA AÇÃO EVANGELIZADORA DA IGREJA CATÓLICA

A proposta de utilização do marketing na ação evangelizadora da Igreja Católica provoca debates entre os diversos segmentos da instituição. Por um lado, setores favoráveis defendem que a utilização do marketing religioso é uma alternativa disponível para Igreja Católica buscar a eficácia na realização de seus objetivos. Por outro lado, setores contrários ao marketing religioso afirmam que há incompatibilidade entre a lógica do marketing e a lógica profética da tradição judaico-cristã. Estes setores assumem a visão de que a lógica do marketing está articulada à lógica da sociedade do consumo, e, portanto, à lógica do capitalismo. Como são críticos ao capitalismo, passam a ser, também, contrários ao uso do marketing na ação eclesial. Diante desta controvérsia, esta dissertação tem o objetivo de mostrar que não há contradição na utilização de algumas técnicas de marketing na ação evangelizadora dos setores católicos comprometidos com a crítica profética à cultura do consumo, a fim de que sua ação profética seja mais eficaz. Nesse sentido, pretendemos mostrar que, de fato, há contradição entre a lógica do marketing e a lógica profética, mas que não existe, necessariamente, contradição entre o uso de algumas técnicas de marketing e a missão profética do cristianismo. Como procedimentos metodológicos, optamos por uma pesquisa bibliográfica a partir dos seguintes referenciais teóricos: Peter Drucker e Philip Kotler foram importantes para fundamentar o significado do marketing nas áreas de Marketing e de Administração. No campo das Ciências da Religião os referenciais teóricos foram Jung Mo Sung, que contribuiu com o estudo das relações entre lógica do mercado, lógica profética e evangelização, e Afonso Murad, que foi importante para articular os conceitos de gestão e de estratégia na ação evangelizadora.(AU)

CONSCIÊNCIA SANITÁRIA: UMA QUESTÃO DE COMUNICAÇÃO E SAÚDE Um estudo sobre a Vigilância Sanitária de Vitória

O trabalho é um estudo de caso baseado na aná lise crítica do processo de comunicação utilizado pela Vigilância Sanitária de Vitória, ES no desenvolvimento de suas funções e no cumprimento de sua missão de prevenção, proteção e recuperação da saúde da população. Através da aplicação de questionários estruturados com perguntas abertas, semi-abertas e fechadas com funcionários do setor e com uma amostra extraída da lista de contribuintes que receberam o alvará sanitário em 2003 confeccionamos um diagnóstico dos problemas comunicacionais existentes e sugerimos mudanças possíveis. Optamos ter como referencial teórico além da teoria crítica, pesquisas realizadas pelo grupo de pensadores Comunicacionais Latino Americanos porque seus trabalhos se aproximam mais da realidade brasileira. Os resultados obtidos elucidam que a comunicação para a saúde ainda não recebe o reconhecimento necessário nas atividades diárias que visam a saúde coletiva, no caso de Vitória. Confirmamos com a pesquisa a hipótese de que as ações da Vigilância Sanitária não se concretizam sem comunicação eficiente e que muito pode ser feito para melhorar o serviço oferecido se os problemas comunicacionais forem sanados.

ESTRATÉGIAS DE EXPANSÃO DE INSTITUIÇÕES DE ENSINO SUPERIOR PRIVADAS NO BRASIL: ESTUDO DE CASO DO CURSO DE BACHARELADO EM ADMINISTRAÇÃO

A dissertação teve como objetivo principal estudar como uma Instituição de Ensino Superior Privada (IES) atuante no Brasil tem crescido pós Lei de Diretrizes e Bases (LDB) de 1996 até 2015, por meio da análise do curso de bacharelado em Administração de Empresas, nas modalidades: presencial, EAD e Flex (semipresencial). Para este fim, foi realizada uma pesquisa exploratória, de caráter qualitativo baseada no método do estudo de caso. Para coleta de evidências foram analisados relatórios corporativos (Annual Report, Relatórios Internos e outros documentos), entrevistas baseadas em roteiro semiestruturado com gestores da IES privada e observações. Dentre os principais achados, verificou-se que as principais estratégicas de crescimento da IES privada estudada se basearam em fusões e aquisições de outras IES, abertura de novos polos de EAD, na abertura de novas unidades próprias, bem como em inovações em várias dimensões da organização. Os programas governamentais de financiamento aos alunos também são fortes contribuintes para este crescimento, como o Fundo de Financiamento ao Estudante do Ensino Superior (FIES) e o Programa Universidade para Todos (Prouni). Com essa nova realidade, o ensino superior privado recebeu incentivo e facilitação para o seu crescimento, a um ritmo acelerado. Consequentemente pode-se concluir que a IES privada estudada adotou as seguintes estratégias de crescimento: Expansão orgânica com fusões/ aquisições de Instituições menores, com desenvolvimento de planos para todos os campi Brasil; Greenfield (por meio de solicitação de autorização de novas unidades e/ou cursos) em cidades sem possibilidades de aquisições/fusões, e aumentando o número de vagas/ matriculas nas unidades já existentes, aderiu aos programas do governo e também cuidou da evasão por meio de: Seguro educacional; gestão preparada para atender necessidades do discente; Sistema de Ensino com currículos integrados nacionalmente; Intercâmbio de alunos e professores entre as diversas unidades em todas as regiões do país e padronização dos processos.

Introduction: special issue on key debates in advertising

Research on advertising has been conducted mainly from within disciplines such as marketing and reception studies. Within translation studies, research has focused more on comparative analysis of language pairs for intersystemic differences, and more recently on intercultural differences in product appeal and cultural values. Advertising as text type was most comprehensively used and developed within Western cultures, then 'exported' to other cultures. Initially the assumption was that the message could be translated and the product would sell on the basis of Western value-based market research, although this is now clearly shown not to be the case, as contributors to this volume all demonstrate through empirical studies. The introduction to this volume offers a comprehensive survey of work done in the field, both within and outside translation studies, outlines the use of semiotics as a suitable framework for research, and summarizes the key issues relating to the global vs. local debate

Good practice guide in learning and teaching

Once again this publication is produced to celebrate and promote good teaching and learning support and to offer encouragement to those imaginative and innovative staff who continue to wish to challenge students to learn to maximum effect. It is hoped that others will pick up some good ideas from the articles contained in this volume. We have again changed our approach for this 2007/08 edition (our fifth) of the Aston Business School Good Practice Guide. As before, some contributions were selected from those identifying interesting best practice on their Annual Module Reflection Forms in 2006/2007. Brookes? contribution this year is directly from her annual reflection. Other contributors received HELM (Research Centre in Higher Education Learning and Management) small research grants in 2006/2007. Part of the conditions were for them to write an article for this publication. We have also been less tight on the length of the articles this year. Some contributions are, therefore, on the way to being journal articles. HELM will be working with these authors to help develop these for publication. Looking back over the last five years it is brilliant to see how many different people have contributed over the years and, therefore, how much innovative learning and teaching work has been taking place in ABS over this time. In the first edition we were just pleased for people to write a few pages on their teaching. Now things have changed dramatically. The majority of the articles are grounded in empirical research (some funded by HELM small research grants) and Palmer?s article was produced as part of the University?s Postgraduate Certificate in Learning and Teaching. Most encouraging of all, four of this year?s articles have since been developed further and submitted to refereed journals. We await news of publication as we go to press. It is not surprising that how to manage large groups still remains a central theme of the articles, ABS has a large and still growing student body. Essex and Simpson have looked at trying to encourage students to attend taught sessions, on the basis that there is a strong correlation between attendance and higher performance. Their findings are forming the platform of a further study currently being carried out in the Undergraduate Programme. A number of the other articles concentrate on trying to encourage students to engage with study in an innovative way. This is particularly obvious in Shaw?s work. Everyone who has been around campus lately has had evidence that the students on Duncan?s modules have clearly been inspired. I found myself, for example, playing golf in the student dining room as part of this initiative! The articles by Jarzabkowski & Guilietti and Ho involved much larger surveys. This is another first for the Good Practice Guide and marks the first step on what will clearly be larger research efforts for these authors in this area. We look forward to the journal publications which will result from this work. The last articles are the result of HELM?s hosting of the national conference of the Higher Education Academy?s Business, Management, Accounting and Finance (BMAF) Subject Centre Conference in May 2007. Belal and Foster have written about their impressions of the Conference and Andrews has included the paper she gave. The papers on employability and widening participation are the centre of HELM?s current work. In the second volume we mentioned the launch of the School?s Research Centre in Higher Education Learning and Management (HELM). Since then HELM has stimulated a lot of activity across the School (and University) particularly linking research and teaching. A list of the HELM seminars for 2007/2008 is listed as Appendix 1 of this publication. Further details can be obtained from Catherine Foster (c.s.foster@aston.ac.uk), who coordinates the HELM seminars. We have also been working on a list of target journals to guide ABS staff who wish to publish in this area. These are included as Appendix 2 of this publication. May I thank the contributors for taking time out of their busy schedules to write the articles and to Julie Green, the Quality Manager, for putting the varying diverse approaches into a coherent and publishable form and for agreeing to fund the printing of this volume.

It is hoped that others will pick up some good ideas from the articles contained in this volume. We have again changed our approach for this 2006/07 edition (our fourth) of the Aston Business School Good Practice Guide. As before, some contributions were selected from those identifying interesting best practice on their Annual Module reflection forms in 2005/2006. Other contributors received HELM (Research Centre in Higher Education Learning and Management) small research grants in 2005/2006. Part of the conditions were for them to write an article for this publication. We have also been less tight on the length of the articles this year. Some contributions are, therefore, on the way to being journal articles. HELM will be working with these authors to help develop these for publication. The themes covered in this year?s articles are all central to the issues faced by those providing HE teaching and learning opportunities in the 21st Century. Specifically this is providing support and feedback to students in large classes, embracing new uses of technology to encourage active learning and addressing cultural issues in a diverse student population. Michael Grojean and Yves Guillaume used Blackboard™ to give a more interactive learning experience and improve feedback to students. It would be easy for other staff to adopt this approach. Patrick Tissington and Qin Zhou (HELM small research grant holders) were keen to improve the efficiency of student support, as does Roger McDermott. Celine Chew shares her action learning project, completed as part of the Aston University PG Certificate in Teaching and Learning. Her use of Blackboard™ puts emphasis on the learner having to do something to help them meet the learning outcomes. This is what learning should be like, but many of our students seem used to a more passive learning experience, so much needs to be done on changing expectations and cultures about learning. Regina Herzfeldt also looks at cultures. She was awarded a HELM small research grant and carried out some significant new research on cultural diversity in ABS and what it means for developing teaching methods. Her results fit in with what many of us are experiencing in practice. Gina leaves us with some challenges for the future. Her paper certainly needs to be published. This volume finishes with Stuart Cooper and Matt Davies reflecting on how to keep students busy in lectures and Pavel Albores working with students on podcasting. Pavel?s work, which was the result of another HELM small research grant, will also be prepared for publication as a journal article. The students learnt more from this work that any formal lecture and Pavel will be using the approach again this year. Some staff have been awarded HELM small research grants in 2006/07 and these will be published in the next Good Practice Guide. In the second volume we mentioned the launch of the School?s Research Centre in Higher Education Learning and Management (HELM).

A list of the HELM seminars for 2006/2007 is listed as Appendix 1 of this publication. Further details can be obtained from Catherine Foster (c.s.foster@aston.ac.uk), who coordinates the HELM seminars. For 2006 and 2005 HELM listed, 20 refereed journal articles, 7 book chapters, 1 published conference papers, 20 conference presentations, two official reports, nine working papers and £71,535 of grant money produced in this research area across the School. I hope that this shows that reflection on learning is alive and well in ABS. We have also been working on a list of target journals to guide ABS staff who wish to publish in this area. These are included as Appendix 2 of this publication. May I thank the contributors for taking time out of their busy schedules to write the articles and to Julie Green, the Quality Manager, for putting the varying diverse approaches into a coherent and publishable form and for agreeing to fund the printing of this volume.
