O Plano Nacional de Educação (PNE) determina que 50% das crianças de 0 a 3 anos tenham vagas garantidas em Creches Públicas e a Lei do Piso n. 11.738/08 apresenta, em seu parágrafo quarto, que na composição da jornada de trabalho do professor observar-se-á um terço destinado à formação. A determinação destas mudanças aumenta a preocupação e responsabilidade em qualificar a formação continuada nestas instituições, as quais ainda sentem o peso dos vários anos de negligência. Pela atualidade e importância temática, a presente abordagem investiga a trajetória formativa e profissional de educadores de Creche, com o objetivo de possibilitar a reflexão e a análise sobre as estratégias utilizadas na formação continuada, bem como um debate dialético entre as práticas e as teorias trazidas nos estudos e pesquisas. Através da metodologia da Pesquisa de Campo de Natureza Qualitativa, buscou-se, ao contatar profissionais de cinco creches do município de São Bernardo do Campo, investigar a seguinte questão: De que forma o Coordenador Pedagógico que atua em creche tem contribuído, ou não, com a formação de profissionais reflexivos, pesquisadores e autores da própria prática? No intuito de responder a questão, foram realizadas entrevistas com cinco Coordenadoras Pedagógicas (CPs), três Professoras e dois Auxiliares em Educação e, em vista de maiores subsídios necessários ao debate, também foram entrevistadas uma Coordenadora de um curso de Pedagogia, com a finalidade de ampliar os conhecimentos sobre o curso de Pedagogia na atualidade, e uma Gestora (Chefe de Região) de São Bernardo do Campo, a fim de entender o olhar que o município tem hoje para a Creche. É importante ressaltar que o foco das entrevistas foi o trabalho desenvolvido pelo CP e que o trabalho investigativo junto aos demais profissionais envolvidos auxiliam na busca e obtenção de respostas para os questionamentos que levaram à construção deste trabalho. Os referenciais teóricos, desenvolvidos através da metodologia da Pesquisa de Natureza Bibliográfica e Documental para a revisão da literatura disponível sobre o tema, estão ancorados em Almeida e Placco (2002; 2010; 2011) que observam o papel do CP sob diversos aspectos; Day (1999) que discute os desafios fundamentais a serem considerados na formação; Fullan e Hargreaves (2002) que apresentam questionamentos sobre as estratégias formativas; Nóvoa (2009) ao investigar sobre a formação permanente dos professores; Perrenoud e Thurler (2002) que destacam novos paradigmas na formação dos professores; Vasconcellos (2009) que observa as articulações necessárias ao trabalho do CP; Campos et al (2011) que mostram a qualidade da Educação Infantil no país, entre outros. A análise dos conteúdos das entrevistas realizadas indica que a formação continuada avança gradativamente e, este mérito é dado, em grande parte, à formação que os gestores vêm recebendo e às parcerias produtivas que se estabelecem no processo, porém, os estudos e pesquisas teóricas apontam que muito ainda precisa ser feito e sinalizam mudanças imprescindíveis e que sejam capazes de impulsionar a formação a sair do tradicionalismo, tornando-se mais voltada à reflexão e humanização.

Manufacturer–reseller interactions are becoming more technology-enabled as channels of distribution increasingly utilize e-business tools on the Internet. This research examines the performance consequences for resellers as these technological advances are applied to distribution activities between channel members. Using a sample of 216 resellers of computer products, the research explores the impact of e-business tools in 2 areas of manufacturer–reseller interactions: supply tasks and demand tasks. The results suggest that e-business in supply tasks increases relationship coordination between manufacturer and reseller, whereas e-business in demand tasks increases coordination as well as conflict within the channel dyad. The increase of conflict constitutes a potential “dark side” of e-business in channel relationships that may provide an explanation for e-business implementation failures and negative returns on investment in technology.

We investigate how boundaries in knowledge control, sharing and co-ordination influence UK and German manufacturing firms’ innovation intensity (an indicator of the volume of product change) and product life (an indicator of the pace of generational change). In general UK plants more commonly face knowledge control boundaries related to plant ownership or control, while German plants more commonly face boundaries related to knowledge sharing and knowledge co-ordination between functional groups. Our empirical results emphasise the importance of the strategic management of innovation. Knowledge control boundaries – related to external ownership, group membership and decision making autonomy – have a weak negative influence on plants’ innovation outcomes. Strategic decisions relating to multifunctional working and networking are found to be more important in overcoming knowledge sharing and co-ordination boundaries. Knowledge sharing boundaries, related to plant or company boundaries, prove most important where a plant has no in-house R&D capability. Knowledge co-ordination boundaries related to functional or multi-functional working have strong but differential effects on different innovation output measures: functional boundaries increase product life in both countries, and in Germany maintaining functional boundaries is also associated with increased innovation intensity.

The research described within this thesis is concerned with the investigation of transition metal ion complexation within hydrophilic copolymer membranes. The membranes are copolymers of 4-methyl-4'-vinyl-2,2'-bipyridine, the 2-hydroxyethyl ester of 4,4'- dicarboxy-2,2'-bipyridine & bis-(5-vinylsalicylidene)ethylenediamine with 2-hydroxyethyl methacrylate. The effect of the polymer matrix on the formation and properties of transition metal iron complexes has been studied, specifically Cr(III) & Fe(II) salts for the bipyridyl- based copolymer membranes and Co(II), Ni(II) & Cu(II) salts for the salenH2- based copolymer membranes. The concomitant effect of complex formation on the properties of the polymer matrix have also been studied, e.g. on mechanical strength. A detailed body of work into the kinetics and thermodynamics for the formation of Cu(II) complexes in the salenH2- based copolymer membranes has been performed. The rate of complex formation is found to be very slow while the value of K for the equilibrium of complex formation is found to be unexpectedly small and shows a slight anion dependence. These phenomena are explained in terms of the effects of the heterogeneous phase provided by the polymer matrix. The transport of Cr(III) ions across uncomplexed and Cr(III)-pre-complexed bipyridyl-based membranes has been studied. In both cases, no Cr(III) coordination occurs within the time-scale of an experiment. Pre-complexation of the membrane does not lead to a change in the rate of permeation of Cr(III) ions. The transport of Co(II), Ni(II) & Cu(II) ions across salenH2- based membranes shows that there is no detectable lag-time in transport of the ions, despite independent evidence that complex formation within the membranes does occur. Finally, the synthesis of a number of functionalised ligands is described. Although they were found to be non-polymerisable by the methods employed in this research, they remain interesting ligands which provide a startmg pomt for further functionalisation.

We have attempted to bring together two areas which are challenging for both IS research and practice: forms of coordination and management of knowledge in the context of global, virtual software development projects. We developed a more comprehensive, knowledge-based model of how coordination can be achieved, and\illustrated the heuristic and explanatory power of the model when applied to global software projects experiencing different degrees of success. We first reviewed the literature on coordination and determined what is known about coordination of knowledge in global software projects. From this we developed a new, distinctive knowledge-based model of coordination, which was then employed to analyze two case studies of global software projects, at SAP and Baan, to illustrate the utility of the model.

By contrast to major constitutional reforms elsewhere in the UK, in England's eight regions beyond London New Labour has favoured administrative decentralisation. This paper examines these institutional arrangements and assesses their capacity to develop a more integrated approach to territorial development. It confirms a growing awareness of the need to ensure greater coherence between policies to promote economic, social and environmental wellbeing. Nonetheless, a complex regional institutional architecture, inconsistent sector-based strategies, a lack of strategic leadership and blurred accountabilities hamper moves towards policy integration and the delivery of joint outcomes. Moreover, despite ongoing reforms, the absence of a clear regional agenda in a functionally designed Whitehall raises fundamental questions about the ability of sub-national bodies to work collectively to develop and implement a more coherent approach to regional policy.

In this paper, we review recent developments in the field of outsourcing and offshoring and the implications for engineering management. We examine three aspects involved in outsourcing and offshoring, namely, sourcing models, coordination, and value extracted from outsourcing projects. We conclude that additional research is needed on recent trends in outsourcing and the impact of such change process on the practice of engineering management. © 2011 IEEE.
