Background: Body mass index ( BMI) is used to diagnose obesity. However, its ability to predict the percentage fat mass (% FM) reliably is doubtful. Therefore validity of BMI as a diagnostic tool of obesity is questioned. Aim: This study is focused on determining the ability of BMI- based cut- off values in diagnosing obesity among Australian children of white Caucasian and Sri Lankan origin. Subjects and methods: Height and weight was measured and BMI ( W/H-2) calculated. Total body water was determined by deuterium dilution technique and fat free mass and hence fat mass derived using age- and gender- specific constants. A % FM of 30% for girls and 20% for boys was considered as the criterion cut- off level for obesity. BMI- based obesity cut- offs described by the International Obesity Task Force ( IOTF), CDC/ NCHS centile charts and BMI- Z were validated against the criterion method. Results: There were 96 white Caucasian and 42 Sri Lankan children. Of the white Caucasians, 19 ( 36%) girls and 29 ( 66%) boys, and of the Sri Lankans 7 ( 46%) girls and 16 ( 63%) boys, were obese based on % FM. The FM and BMI were closely associated in both Caucasians ( r = 0.81, P < 0.001) and Sri Lankans ( r = 0.92, P< 0.001). Percentage FM and BMI also had a lower but significant association. Obesity cut- off values recommended by IOTF failed to detect a single case of obesity in either group. However, NCHS and BMI- Z cut- offs detected cases of obesity with low sensitivity. Conclusions: BMI is a poor indicator of percentage fat and the commonly used cut- off values were not sensitive enough to detect cases of childhood obesity in this study. In order to improve the diagnosis of obesity, either BMI cut- off values should be revised to increase the sensitivity or the possibility of using other indirect methods of estimating the % FM should be explored.

Os Cursos Superiores de Tecnologia são um tipo específico de graduação (tecnólogo), com características próprias, entre as quais, a focalização na especialização dos seus currículos e duração mais curta objetivando uma formação mais rápida. A graduação tecnológica vem sendo amplamente difundida no país desde a segunda metade da década de 1990, após a promulgação da lei no 9.394/96 LDB, e por uma série de decretos, portarias e pareceres do MEC/CNE. Entre as principais metas e objetivos do PNE para a educação superior, se destacam: diversificação do sistema superior de ensino para atender clientelas com demandas específicas de formação; articulação entre currículo e mercado de trabalho; financiamento e gestão; criação de políticas de acesso à educação superior que facilitem o ingresso de alunos provenientes de grupos de maior vulnerabilidade educacional; crescimento da oferta de educação superior para a faixa etária de 18 a 24 anos. O presente estudo tem por objetivo refletir e debater a contribuição dos CSTs na educação profissional do trabalhador brasileiro dentro das perspectivas do PNE. O estudo se fundamenta no método qualitativo, com base numa pesquisa exploratória e descritiva, caracterizada como estudo de caso único, através da pesquisa de campo realizada com alunos em formação e com egressos do Curso de Eletrônica Industrial da Faculdade de Tecnologia Senai Anchieta, na cidade de São Paulo. Para alcançar seus objetivos, o estudo foi dividido em duas etapas: a primeira faz uma análise das variáveis que caracterizam o perfil do aluno em formação buscando identificar sua percepção quanto à escolha pelo CST, conhecimento sobre essa modalidade de ensino e as expectativas futuras da profissão. Na segunda parte, o estudo faz uma análise da percepção do egresso acerca das habilidades e competências adquiridas durante a formação, o grau de satisfação com salário e plano de carreira, e a aceitação profissional do tecnólogo pelo mercado de trabalho. No estudo realizado com alunos em formação constatou-se que os índices de evasão escolar das primeiras turmas do curso foram elevados, sendo apontadas como principais causas as dificuldades de conciliação entre o horário de estudo com a do trabalho e as dificuldades econômicas familiares. O perfil do aluno em formação na IES em estudo é majoritariamente da faixa etária entre 18 e 24 anos; do gênero masculino; egresso do ensino médio feito em escola pública; morador em bairro periférico e natural de cidade da RMSP; o próprio aluno é responsável pelo pagamento das mensalidades; não houve interferência de terceiros na sua escolha pelo CST; tem percepção favorável quanto à empregabilidade futura como tecnólogo. A pesquisa com egressos apontou que os mesmos tem percepção favorável quanto à formação profissional recebida, exceto o fato de não terem atendido disciplinas que desenvolvessem competências gerenciais e de negócios; quanto à empregabilidade e perspectivas de carreira mostraram preocupação na valorização profissional do tecnólogo pelo mercado de trabalho; declararam estar insatisfeitos quanto ao salário recebido; quanto à educação continuada reconheceram ser esse o processo que os manterão atualizados profissionalmente. Como conclusão da pesquisa, há recomendação para estudos futuros na sondagem de outras possíveis causas da evasão escolar com alunos dos cursos com outros eixos temáticos e de IES públicas. Igualmente, aponta-se para a necessidade da proposta curricular da IES em estudo oferecer, além das disciplinas técnicas, outras que desenvolvam competências e habilidade em gestão de pessoas e negócios.

A ação reduzida do Estado brasileiro com relação ao atendimento das necessidades das crianças e adolescentes em situação de rua dá espaço para a atuação de novos atores sociais. Alguns destes têm como objetivo promover a cidadania do país, como os participantes do terceiro setor: ONGs que enfrentam diversos obstáculos para realizar suas missões. Dentre estes desafios encontra-se a gestão de pessoas. O presente trabalho propõe a análise da gestão de pessoas e a construção participativa de um modelo de competências em uma Organização Não Governamental Projeto Meninos e Meninas de Rua, a partir da combinação das metodologias qualitativas de estudo de caso único e pesquisa-ação, tendo como embasamento a Gestão Social. A pesquisa de campo foi desenvolvida por meio de diferentes fontes de evidências: entrevistas, questionários, observação, análise de documentos e registros e artefatos físicos, que permitiu a construção participativa de um modelo com cinco (5) competências essenciais/institucionais: Diagnóstico e Planejamento, Alinhamento Institucional, Comunicação, Resiliência e Defesa, Garantia e Promoção de Direitos, tendo como foco deste trabalho o olhar para os Educadores Sociais que atuam na instituição.

Por um lado, o mundo do Século XXI com ferramentas que possibilitam cada vez mais estarmos conectados e dependentes das tecnologias de comunicação, em que a internet prevalece como meio principal para as pessoas se relacionarem, interagirem, consumirem, se divertirem e se informarem. Do outro lado, quase que uma ilha à parte dessa tendência tecnológica, um espaço em que a comunicação oral, a confiança, o valor da palavra, o conhecer o vizinho do bairro e a comunidade são o que prevalece. Trata-se de mais um fenômeno decorrente do crescimento da Classe C no Brasil, posterior ao lançamento do Plano Real, por Fernando Henrique Cardoso no governo do ex-presidente Itamar Franco, e da implantação de medidas sociais nos anos seguintes, durante o governo de Luiz Inácio Lula da Silva. O segmento que representa 54% da população brasileira e desperta a atenção das empresas como uma nova frente de geração de riquezas e negócios. Por meio de pesquisa bibliográfica e análise documental para análise de conteúdo, este estudo de caso único investigará como o Banco Itaú se comunica com esse público para oferecer o microcrédito na periferia da cidade de São Paulo. Num mundo em que se pensa quanto mais rápidas e sensoriais serão as tecnologias de informação no futuro, o bom e velho bate-papo pode levar a conhecimentos importantes quando queremos nos comunicar com as camadas populares da população.

Este estudo tem como objetivo analisar como os processos comunicacionais de manifestações perceptivas dos consumidores pós-modernos, a partir das interações em redes sociais virtuais, contribuem para a ressignificação da imagem de marca. Reavaliamos o processo comunicacional ante as novas interações econômicas e tecno-sociais, partindo de uma visão de consumo de significados e um deslocamento do marketing das necessidades para um marketing de sentidos. Para tanto, desenvolvemos um estudo de caso único da marca Lego, a partir de levantamento bibliográfico, levantamentos qualitativos das interações em sites, análise de conteúdo de blog e análise qualitativa de fórum de consumidores da marca. Assim, concluímos que a comunicação de mercado assume um papel aglutinador nas construções simbólicas da imagem de marca nas organizações e que a facilidade econômica e atemporal em compartilhar manifestações por meio da internet ressignifica a imagem de marca em um papel de troca simbólica na bolsa de valores de imagens das redes on-line.

Purpose - The purpose of this research paper is to demonstrate how existing performance measurement may be adopted to measure and manage performance in extended enterprises. Design/methodology/approach - The paper reviews the literature in performance measurement and extended enterprises. It explains the collaborative architecture of an extended enterprise and demonstrates this architecture through a case study. A model for measuring and managing performance in extended enterprises is developed using the case study. Findings - The research found that due to structural differences between traditional and extended enterprises, the systems required to measure and manage the performance of extended enterprises, whilst being based upon existing performance measurement frameworks, would be structurally and operationally different. Based on this, a model for measuring and managing performance in extended enterprises is proposed which includes intrinsic and extrinsic inter-enterprise coordinating measures. Research limitations/implications - There are two limitations this research. First, the evidence is based on a single case, thus further cases should be studied to establish the generalisibility of the presented results. Second, the practical limitations of the EE performance measurement model should be established through longitudinal action research. Practical implications - In practice the model proposed requires collaborating organisations to be more open and share critical performance information with one another. This will require change in practices and attitudes. Originality/value - The main contribution this paper makes is that it highlights the structural differences between traditional and collaborative enterprises and specifies performance measurement and management requirements of these collaborative organisations. © Emerald Group Publishing Limited.

Purpose: The business process outsourcing (BPO) industry in India is evolving rapidly, and one of the key characteristics of this industry is the emergence of high-end services offered by knowledge processing outsourcing (KPO) organizations. These organizations are set to grow at a tremendous pace. Given the people-intensive nature of this industry, efficient employee management is bound to play a critical role. The literature lacks studies offering insights into the HR challenges involved and the ways in which they are addressed by KPOs. The purpose of this paper is to attempt to fill this gap by presenting findings from an in-depth case study of a KPO organization. Design/methodology/ approach: To achieve the research objective we adopted an in-depth case study approach. The research setting was that of a KPO organization in India, which specialises in offering complex analytics, accounting and support services to the real estate and financial services industries. Findings: The results of this study highlight the differences in the nature of work characteristics in such organizations as compared to call centres. The study also highlights some of the key people management challenges that these organizations face like attracting and retaining talent. The case company adopts formal, structured, transparent and innovative human resource practices. The study also highlights that such enlightened human resource practices stand on the foundations laid by an open work environment and facilitative leadership. Research limitations/implications: One of the key limitations is that the analysis is based on primary data from a single case study and only 18 interviews. The analysis contributes to the fields of KPO, HRM and India and has key messages for policy makers. Originality/value: The literature on outsourcing has in general focused on call centres established in the developed world. However, the booming BPO industry in India is also beginning to offer high-end services, which are far above the typical call centres. These KPOs and their people management challenges are relatively unexplored territories in the literature. By conducting this study in an emerging market (India) and focusing on people-related challenges in KPOs, this study attempts to provide a fresh perspective to the extant BPO literature. © Emerald Group Publishing Limited.

Purpose - The purpose of this paper is to show how QFD can be used as part of a structured planning and analysis framework for micro-sized enterprises to build-up their e-business capabilities. Design/methodology/approach - This case study has been produced using a new framework which integrates the balanced scorecard, value chain and quality function deployment techniques into an integrated framework known as the E-Business Planning and Analysis Framework (E-PAF). It has been produced using an action research approach. Findings - A new framework with a supporting case study is provided. This case study has demonstrated that the framework can be applied successfully to micro-sized enterprises (those with less than ten employees) to successfully plan new strategic and technical developments. This will enhance the online service that the company is able to provide. Research limitations/implications - This paper presents a single case study. The technical recommendations are currently being implemented. Originality/value - Such analytical techniques are most commonly associated with large organisations, and are not specifically associated with e-business planning. This paper provides a new framework that will be of general applicability to other similarly sized enterprises that are looking to improve e-business capabilities. © Emerald Group Publishing Limited.

Purpose - Managers at the company attempt to implement a knowledge management information system in an attempt to avoid loss of expertise while improving control and efficiency. The paper seeks to explore the implications of the technological solution to employees within the company. Design/methodology/approach - The paper reports qualitative research conducted in a single organization. Evidence is presented in the form of interview extracts. Findings - The case section of the paper presents the accounts of organizational participants. The accounts reveal the workers' reactions to the technology-based system and something of their strategies of resistance to the system. These accounts also provide glimpses of the identity construction engaged in by these knowledge workers. The setting for the research is in a knowledge-intensive primary industry. Research was conducted through observation and interviews. Research limitations/implications - The issues identified are explored in a single case-study setting. Future research could look at the relevance of the findings to other settings. Practical implications - The case evidence presented indicates some of the complexity of implementation of information systems in organizations. This could certainly be seen as more evidence of the uncertainty associated with organizational change and of the need for managers not to expect an easy adoption of intrusive IT solutions. Originality/value - This paper adds empirical insight to a largely conceptual literature. © Emerald Group Publishing Limited.

The IRDS standard is an international standard produced by the International Organisation for Standardisation (ISO). In this work the process for producing standards in formal standards organisations, for example the ISO, and in more informal bodies, for example the Object Management Group (OMG), is examined. This thesis examines previous models and classifications of standards. The previous models and classifications are then combined to produce a new classification. The IRDS standard is then placed in a class in the new model as a reference anticipatory standard. Anticipatory standards are standards which are developed ahead of the technology in order to attempt to guide the market. The diffusion of the IRDS is traced over a period of eleven years. The economic conditions which affect the diffusion of standards are examined, particularly the economic conditions which prevail in compatibility markets such as the IT and ICT markets. Additionally the consequences of the introduction of gateway or converter devices into a market where a standard has not yet been established is examined. The IRDS standard did not have an installed base and this hindered its diffusion. The thesis concludes that the IRDS standard was overtaken by new developments such as object oriented technologies and middleware. This was partly because of the slow development process of developing standards in traditional organisations which operate on a consensus basis and partly because the IRDS standard did not have an installed base. Also the rise and proliferation of middleware products resulted in exchange mechanisms becoming dominant rather than repository solutions. The research method used in this work is a longitudinal study of the development and diffusion of the ISO/EEC IRDS standard. The research is regarded as a single case study and follows the interpretative epistemological point of view.

The aim of this research is to investigate how risk management in a healthcare organisation can be supported by knowledge management. The subject of research is the development and management of existing logs called "risk registers", through specific risk management processes employed in a N.H.S. (Foundation) Trust in England, in the U.K. Existing literature on organisational risk management stresses the importance of knowledge for the effective implementation of risk management programmes, claiming that knowledge used to perceive risk is biased by the beliefs of individuals and groups involved in risk management and therefore is considered incomplete. Further, literature on organisational knowledge management presents several definitions and categorisations of knowledge and approaches for knowledge manipulation in the organisational context as a whole. However, there is no specific approach regarding "how to deal" with knowledge in the course of organisational risk management. The research is based on a single case study, on a N.H.S. (Foundation) Trust, is influenced by principles of interpretivism and the frame of mind of Soft Systems Methodology (S.S.M.) to investigate the management of risk registers, from the viewpoint of people involved in the situation. Data revealed that knowledge about risks and about the existing risk management policy and procedures is situated in several locations in the Trust and is neither consolidated nor present where and when required. This study proposes a framework that identifies required knowledge for each of the risk management processes and outlines methods for conversion of this knowledge, based on the SECI knowledge conversion model, and activities to facilitate knowledge conversion so that knowledge is effectively used for the development of risk registers and the monitoring of risks throughout the whole Trust under study. This study has theoretical impact in the management science literature as it addresses the issue of incomplete knowledge raised in the risk management literature using concepts of the knowledge management literature, such as the knowledge conversion model. In essence, the combination of required risk and risk management related knowledge with the required type of communication for risk management creates the proposed methods for the support of each risk management process for the risk registers. Further, the indication of the importance of knowledge in risk management and the presentation of a framework that consolidates knowledge required for the risk management processes and proposes way(s) for the communication of this knowledge within a healthcare organisation have practical impact in the management of healthcare organisations.

The aim of this project was to develop the education work of an environmental pressure group. The research devised and implemented a project to produce multi-media teaching packs on the urban environment. Whilst this involved understanding environmental education it was necessary to research beyond this to include the various structural and dynamic constraints on change in the field. This presented a number of methodological difficulties; from the resolution of which a model of the research process involved in this project has been developed. It is argued that research oriented towards practical change requires the insights of an experienced practitioner to be combined with the rigours of controlled systematic enquiry. Together these function as a model-building process encompassing intuition, induction and deduction. Model testing is carried out through repeated intervention in the field; thus an interplay between researcher and client ensues such that the project develops in a mutually acceptable direction. In practice, this development will be both unpredictable and erratic. Although the conclusions reached here are based on a single case study they address general methodological issues likely to be encountered in different field settings concerned with different practical problems.

The importance of an organisation wide market oriented culture revolves around the performance implications of a focus on customers. However, in contemporary multiple stakeholder environments different notions of ‘the customer’ can exist adding complexity and introducing the possibility of different market oriented subcultures. An analysis of managers’ cognitive maps within a single case study highlight different beliefs and values associated with two alternative market oriented subcultures externally driven by a focus on two different customer groups. The lack of management consensus was further emphasised by two other alternative internally driven subcultures within the same firm. The implications are briefly discussed.

Purpose – This paper aims to focus on developing critical understanding in human resource management (HRM) students in Aston Business School, UK. The paper reveals that innovative teaching methods encourage deep approaches to study, an indicator of students reaching their own understanding of material and ideas. This improves student employability and satisfies employer need. Design/methodology/approach – Student response to two second year business modules, matched for high student approval rating, was collected through focus group discussion. One module was taught using EBL and the story method, whilst the other used traditional teaching methods. Transcripts were analysed and compared using the structure of the ASSIST measure. Findings – Critical understanding and transformative learning can be developed through the innovative teaching methods of enquiry-based learning (EBL) and the story method. Research limitations/implications – The limitation is that this is a single case study comparing and contrasting two business modules. The implication is that the study should be replicated and developed in different learning settings, so that there are multiple data sets to confirm the research finding. Practical implications – Future curriculum development, especially in terms of HE, still needs to encourage students and lecturers to understand more about the nature of knowledge and how to learn. The application of EBL and the story method is described in a module case study – “Strategy for Future Leaders”. Originality/value – This is a systematic and comparative study to improve understanding of how students and lecturers learn and of the context in which the learning takes place.
A conceptual framework for supply chain collaboration:empirical evidence from the agri-food industry
Resumo:
Purpose - The purpose of this paper is to analyse the concept of supply chain collaboration and to provide an overall framework that can be used as a conceptual landmark for further empirical research. In addition, the concept is explored in the context of agri-food industry and particularities are identified. Finally, the paper submits empirical evidence from an exploratory case study in the agri-food industry, at the grower-processor interface, and information regarding the way the concept is actually applied in small medium-sized enterprises (SMEs) is presented. Design/methodology/approach - The paper employed case study research by conducting in-depth interviews in the two companies. Findings - Supply chain collaboration concept is of significant importance for the agri-food industry however, some constraints arise due to the nature of industry's products, and the specific structure of the sector. Subsequently, collaboration in the supply chain is often limited to operational issues and to logistics-related activities. Research limitations/implications - Research is limited to a single case study and further qualitative testing of the conceptual model is needed in order to adjust the model before large scale testing. Practical implications - Case study findings may be transferable to other similar dual relationships at the grower-processor interface. Weaker parts in asymmetric relationships have opportunities to improve their position, altering the dependence balance, by achieving product/process excellence. Originality/value - The paper provides evidence regarding the applicability of the supply chain collaboration concept in the agri-food industry. It takes into consideration not relationships between big multinational companies, but SMEs. © Emerald Group Publishing Limited.
