Productividad, innovación y uso de tecnologías de información y las comunicaciones (tic) como factores de desarrollo de la micro, pequeña y mediana empresa (mipyme) en Bogotá.

Las TIC han impactado en el funcionamiento de las organizaciones y han aportado a su proceso evolutivo, generando diversos efectos de acuerdo a la función que estas cumplen dentro de la organización. Las TIC como consecuencia se convierten en una estrategia de gestión en un entorno complejo donde permiten alcanzar mejoras en la organización social, la actividad económica, el bienestar y el acceso a la información y el conocimiento. (Cáceres Carrasco & Aceytuno Pérez, 2008)Con el fin de entender los beneficios de las TIC, se deben brindar a los directores herramientas que permitan formular modelos de negocios efectivos de cara a los mercados y enfocadas a la satisfacción de los clientes. Adicionalmente, para las organizaciones el añadir valor, no sólo hace referencia al servicio que están prestando; hay otros factores diferentes al uso de herramientas TIC y la innovación que también son igual de importantes como: los procesos de apoyo, de gestión que se encuentran de fondo y que hacen posible brindar un servicio al mercado, en estos procesos se encuentran aplicaciones de procedimientos amigables y fáciles de articular, temas como la responsabilidad empresarial, relación y comunicación con competidores dentro del mismo sector, es justamente en las relaciones con los clientes, que las TIC y el uso de Internet puede tener incidencia en los modelos de negocios a través de actividades como el comercio electrónico, el mercadeo electrónico, el mercadeo en línea entre otros. Existen investigaciones acerca de estos temas: innovación, TI, pero no se han establecido relaciones entre ellos, debido a su novedad. Diferentes experiencias laborales de los investigadores en el uso de las TIC como herramienta en la organización de información permiten que surja la idea de llevar a cabo este proyecto abarcando la realidad bogotana de las MiPyme. La presente investigación con un enfoque cualitativo hace una revisión bibliográfica, y bajo la mirada teórica se analiza la relación que tienen los factores de desarrollo que se evidenciaron como son la innovación y el uso de herramientas TIC, como variables dependientes de la productividad de las MiPyme en Bogotá, Colombia, involucrando temas que se relacionan con distintos campos como la tecnología, políticas gubernamentales, y economía.

The extrapolation problem and how population modeling can help

We argue that population modeling can add value to ecological risk assessment by reducing uncertainty when extrapolating from ecotoxicological observations to relevant ecological effects. We review other methods of extrapolation, ranging from application factors to species sensitivity distributions to suborganismal (biomarker and "-omics'') responses to quantitative structure activity relationships and model ecosystems, drawing attention to the limitations of each. We suggest a simple classification of population models and critically examine each model in an extrapolation context. We conclude that population models have the potential for adding value to ecological risk assessment by incorporating better understanding of the links between individual responses and population size and structure and by incorporating greater levels of ecological complexity. A number of issues, however, need to be addressed before such models are likely to become more widely used. In a science context, these involve challenges in parameterization, questions about appropriate levels of complexity, issues concerning how specific or general the models need to be, and the extent to which interactions through competition and trophic relationships can be easily incorporated.

Benchmarking consensus model quality assessment for protein fold recognition

Background: Selecting the highest quality 3D model of a protein structure from a number of alternatives remains an important challenge in the field of structural bioinformatics. Many Model Quality Assessment Programs (MQAPs) have been developed which adopt various strategies in order to tackle this problem, ranging from the so called "true" MQAPs capable of producing a single energy score based on a single model, to methods which rely on structural comparisons of multiple models or additional information from meta-servers. However, it is clear that no current method can separate the highest accuracy models from the lowest consistently. In this paper, a number of the top performing MQAP methods are benchmarked in the context of the potential value that they add to protein fold recognition. Two novel methods are also described: ModSSEA, which based on the alignment of predicted secondary structure elements and ModFOLD which combines several true MQAP methods using an artificial neural network. Results: The ModSSEA method is found to be an effective model quality assessment program for ranking multiple models from many servers, however further accuracy can be gained by using the consensus approach of ModFOLD. The ModFOLD method is shown to significantly outperform the true MQAPs tested and is competitive with methods which make use of clustering or additional information from multiple servers. Several of the true MQAPs are also shown to add value to most individual fold recognition servers by improving model selection, when applied as a post filter in order to re-rank models. Conclusion: MQAPs should be benchmarked appropriately for the practical context in which they are intended to be used. Clustering based methods are the top performing MQAPs where many models are available from many servers; however, they often do not add value to individual fold recognition servers when limited models are available. Conversely, the true MQAP methods tested can often be used as effective post filters for re-ranking few models from individual fold recognition servers and further improvements can be achieved using a consensus of these methods.

FunFOLDQA: a quality assessment tool for protein-ligand binding site residue predictions

The estimation of prediction quality is important because without quality measures, it is difficult to determine the usefulness of a prediction. Currently, methods for ligand binding site residue predictions are assessed in the function prediction category of the biennial Critical Assessment of Techniques for Protein Structure Prediction (CASP) experiment, utilizing the Matthews Correlation Coefficient (MCC) and Binding-site Distance Test (BDT) metrics. However, the assessment of ligand binding site predictions using such metrics requires the availability of solved structures with bound ligands. Thus, we have developed a ligand binding site quality assessment tool, FunFOLDQA, which utilizes protein feature analysis to predict ligand binding site quality prior to the experimental solution of the protein structures and their ligand interactions. The FunFOLDQA feature scores were combined using: simple linear combinations, multiple linear regression and a neural network. The neural network produced significantly better results for correlations to both the MCC and BDT scores, according to Kendall’s τ, Spearman’s ρ and Pearson’s r correlation coefficients, when tested on both the CASP8 and CASP9 datasets. The neural network also produced the largest Area Under the Curve score (AUC) when Receiver Operator Characteristic (ROC) analysis was undertaken for the CASP8 dataset. Furthermore, the FunFOLDQA algorithm incorporating the neural network, is shown to add value to FunFOLD, when both methods are employed in combination. This results in a statistically significant improvement over all of the best server methods, the FunFOLD method (6.43%), and one of the top manual groups (FN293) tested on the CASP8 dataset. The FunFOLDQA method was also found to be competitive with the top server methods when tested on the CASP9 dataset. To the best of our knowledge, FunFOLDQA is the first attempt to develop a method that can be used to assess ligand binding site prediction quality, in the absence of experimental data.

Building from scratch a marketing services giant by acquisition: case study and interview with Sir Martin Sorrell, Chief Executive of WPP

Purpose – Mergers and acquisitions are among the most intensely used strategic decisions. Yet research by both academics and consulting groups suggests that many mergers and acquisitions fail to add value. On the other hand there are many companies that successfully use mergers and acquisition to grow and add shareholder value. One such company is WPP. The aim of this paper is to explore why WPP has been successful in its acquisition strategy while so many other companies fail. Design/methodology/approach – The paper draws on documentary evidence and a semi-structured interview with Sir Martin Sorrell – Chief Executive and founder of WPP. Research limitations/implications – The case study offers a unique insight into thinking of a successful acquirer and sheds light on how mergers and acquisitions are managed by WPP. However, because of its design the findings are not generalisable. Originality/value – This case study sheds light on how mergers and acquisitions can be used to create a £9 billion company from a standing start. Furthermore, very few case studies offer insight into the thinking of entrepreneurial Chief Executives who established the business, grew it to become the largest and most profitable marketing services company in the world and engineered close to 300 acquisitions.

Informing operational flood management with ensemble predictions: lessons from Sweden.

This paper highlights some communicative and institutional challenges to using ensemble prediction systems (EPS) in operational flood forecasting, warning, and civil protection. Focusing in particular on the Swedish experience, as part of the PREVIEW FP6 project, of applying EPS to operational flood forecasting, the paper draws on a wider set of site visits, interviews, and participant observation with flood forecasting centres and civil protection authorities (CPAs) in Sweden and 15 other European states to reflect on the comparative success of Sweden in enabling CPAs to make operational use of EPS for flood risk management. From that experience, the paper identifies four broader lessons for other countries interested in developing the operational capacity to make, communicate, and use EPS for flood forecasting and civil protection. We conclude that effective training and clear communication of EPS, while clearly necessary, are by no means sufficient to ensure effective use of EPS. Attention must also be given to overcoming the institutional obstacles to their use and to identifying operational choices for which EPS is seen to add value rather than uncertainty to operational decision making by CPAs.

A semiotic framework for information representation of energy consumption in office buildings

Taking a perspective from a whole building lifecycle, occupier's actions could account for about 50% of energy. However occupants' activities influence building energy performance is still a blind area. Building energy performance is thought to be the result of a combination of building fabrics, building services and occupants' activities, along with their interactions. In this sense, energy consumption in built environment is regarded as a socio-technical system. In order to understand how such a system works, a range of physical, technical and social information is involved that needs to be integrated and aligned. This paper has proposed a semiotic framework to add value for Building Information Modelling, incorporating energy-related occupancy factors in a context of office buildings. Further, building information has been addressed semantically to describe a building space from the facility management perspective. Finally, the framework guides to set up building information representation system, which can help facility managers to manage buildings efficiently by improving their understanding on how office buildings are operated and used.

Ensemble downscaling in coupled solar wind-magnetosphere modeling for space weather forecasting

Advanced forecasting of space weather requires simulation of the whole Sun-to-Earth system, which necessitates driving magnetospheric models with the outputs from solar wind models. This presents a fundamental difficulty, as the magnetosphere is sensitive to both large-scale solar wind structures, which can be captured by solar wind models, and small-scale solar wind “noise,” which is far below typical solar wind model resolution and results primarily from stochastic processes. Following similar approaches in terrestrial climate modeling, we propose statistical “downscaling” of solar wind model results prior to their use as input to a magnetospheric model. As magnetospheric response can be highly nonlinear, this is preferable to downscaling the results of magnetospheric modeling. To demonstrate the benefit of this approach, we first approximate solar wind model output by smoothing solar wind observations with an 8 h filter, then add small-scale structure back in through the addition of random noise with the observed spectral characteristics. Here we use a very simple parameterization of noise based upon the observed probability distribution functions of solar wind parameters, but more sophisticated methods will be developed in the future. An ensemble of results from the simple downscaling scheme are tested using a model-independent method and shown to add value to the magnetospheric forecast, both improving the best estimate and quantifying the uncertainty. We suggest a number of features desirable in an operational solar wind downscaling scheme.

The perceived impact of the National Health Service on personalised nutrition service delivery among the UK public

Personalised nutrition (PN) has the potential to reduce disease risk and optimise health and performance. Although previous research has shown good acceptance of the concept of PN in the UK, preferences regarding the delivery of a PN service (e.g. online v. face-to-face) are not fully understood. It is anticipated that the presence of a free at point of delivery healthcare system, the National Health Service (NHS), in the UK may have an impact on end-user preferences for deliverances. To determine this, supplementary analysis of qualitative data obtained from focus group discussions on PN service delivery, collected as part of the Food4Me project in the UK and Ireland, was undertaken. Irish data provided comparative analysis of a healthcare system that is not provided free of charge at the point of delivery to the entire population. Analyses were conducted using the 'framework approach' described by Rabiee (Focus-group interview and data analysis. Proc Nutr Soc 63, 655-660). There was a preference for services to be led by the government and delivered face-to-face, which was perceived to increase trust and transparency, and add value. Both countries associated paying for nutritional advice with increased commitment and motivation to follow guidelines. Contrary to Ireland, however, and despite the perceived benefit of paying, UK discussants still expected PN services to be delivered free of charge by the NHS. Consideration of this unique challenge of free healthcare that is embedded in the NHS culture will be crucial when introducing PN to the UK.

Logística : análise dos serviços ao cliente e do perfil do pedido - o caso Plaything S.A.

A logística é, atualmente, um dos mais importantes diferenciais competitivos existentes em empresas do mundo inteiro. Ela envolve todas as áreas da empresa, o que dificulta o esgotamento de uma discussão profunda sobre este tema. Este estudo de caso se propõe a analisar alguns aspectos deste conceito, mais precisamente aqueles voltados para o serviço ao cliente e seu reflexo no sistema de distribuição de uma empresa. O objetivo deste trabalho é fornecer informações que possibilitem definir uma estrutura de distribuição que seja capaz de adicionar valor para seus clientes e vantagem competitiva para a empresa. Nesta discussão, através de uma pesquisa bibliográfica, ficou claro que as necessidades do cliente definem os serviços a serem oferecidos pela empresa, e, através de uma pesquisa de campo, ficaram estabelecidos quais são estes serviços. Para este estudo de caso, foi escolhida uma empresa de brinquedos, a Plaything S/A Ind. e Com., com marcante atuação nacional, em que se discute seu conjunto de serviços sob o aspecto externo e interno. No aspecto externo, através de uma pesquisa, estabelece-se uma hierarquização de necessidades dos clientes e verifica-se se os serviços oferecidos por esta empresa estão de acordo com estas necessidades. Ao mesmo tempo, esta pesquisa posiciona a empresa em relação a seus concorrentes quanto à satisfação das necessidades de seus clientes, ou seja, define gaps existentes entre necessidades e serviços oferecidos. No aspecto interno, busca definir o perfil do pedido desta empresa como forma de adequar sua estrutura e processo de armazenagem. Através desta análise, constata-se que a empresa estudada oferece um nível de serviço cuja satisfação está de acordo com seus concorrentes, porém aquém do que esperam seus clientes. Conclui-se ainda que o perfil do cliente provoca diferenças de percepção quanto à importância e à satisfação dos atributos pesquisados. O estudo do perfil do pedido revela que esta empresa tem pedidos de pequeno valor, pouco freqüentes e com poucos itens. Este perfil obriga a empresa a maximizar sua estrutura interna de distribuição física, tanto em termos de processos de armazenagem como de separação e manuseio dos produtos. Na conclusão do trabalho, são apresentas algumas recomendações à empresa pesquisada, levando-se em consideração os resultados da pesquisa e a necessidade de optar-se por estratégias que sejam inovadoras, adequadas ao rápido processo de mudanças de conceitos da época atual.

Cultura e desenvolvimento local: um estudo do Programa Bairro-Escola da cidade de Nova Iguaçu

A relação entre cultura e desenvolvimento é um dos assuntos centrais dos debates contemporâneos que vão além do ambiente acadêmico e atinge a agenda política em diversos países. A cultura exerce um papel importante para o desenvolvimento que não se restringe à dimensão econômica, pois é capaz de construir ou reconstruir identidades, elevar a auto-estima individual e coletiva, adicionar valor ao patrimônio existencial humano. Faz-se necessário, ainda, um outro conceito de desenvolvimento, calcado em outras lógicas, sendo geográfica, social e culturalmente referenciado e promovendo uma transformação social profunda. No Brasil, alguns governos locais vêm assumindo o seu papel de protagonista do desenvolvimento com base nessa proposta. Em Nova Iguaçu - cidade localizada na Baixada fluminense - vem sendo desenvolvida uma política pública cujo protagonista e indutora é a Prefeitura municipal. Trata-se do Programa Bairro-Escola que, embora tenha como centralidade a educação, articula diversas secretarias da prefeitura e promove benefícios e oportunidades sociais às crianças, adolescentes e aos demais moradores da cidade que extrapolam o aspecto educacional. Para a sua operacionalização, a Prefeitura desenvolve parcerias com atores de diversas naturezas. O objetivo dessa dissertação foi compreender de que maneira o Bairro-Escola de Nova Iguaçu, especialmente seus programas, projetos e ações culturais, contribui para o desenvolvimento local. No que diz respeito à metodologia, a estratégia de pesquisa adotada, foi o estudo de caso. Para a coleta dos dados primários e secundários foram adotadas duas técnicas, a saber: bibliográfica-documental; e entrevistas semi-estruturadas com alguns representantes do Bairro-Escola e da Secretaria de Cultura de Nova Iguaçu. Os resultados indicam que o Bairro-Escola aponta para um esforço de inclusão e desenvolvimento social por meio de programas e ações integradas. Em síntese, as contribuições ao desenvolvimento proporcionadas pelo Bairro-Escola, pelas vias da cultura, em Nova Iguaçu são: ampliação do acesso da população à leitura - criação de cinco bibliotecas ramais nas Escolas da Rede Pública Municipal e reequipamento de duas bibliotecas comunitárias; criação de uma Escola de ensino e formação em audiovisual (Escola Livre de Cinema), com núcleos em quatro bairros da cidade; criação de uma Escola Livre de Música Eletrônica, atendendo, inicialmente, a 400 crianças beneficiárias do Bairro-Escola; oportunidade de experimentação artística para quase 7.000 crianças e jovens; capacitação de 52 artistas locais em artes cênicas; criação de um grupo cultural formado por artistas locais (Grupo Nós da Baixada) - grupo de artes cênicas no bairro Cerâmica; oportunidade de estágio (renda e aperfeiçoamento profissional) para cerca de 90 jovens nas oficinas culturais; perspectiva de trabalho para 96 grupos artístico-culturais locais, por meio do convênio com o Ministério da Cultura; fortalecimento de grupos artístico-culturais locais, por meio de assessoramento para a profissionalização e desenvolvimento desses grupos.

Visões das gerências da auditoriainterna da Petrobras sobre a sua estratégia de atuação em facedas práticas de mercado e da nova modelagem organizacional da companhia

The purpose of this study is to identify the strategic vision of the Internal Audit Department of Petrel Brasileiro S.A. PETROBRAS, in comparison with the audit function's proposals and practices in competitive organizations and their reality. It also aims at the verification of the possible solutions, within Petrobras itself, so as to constantly add value to the business and to the shareholders. With this in mind, a research was carried out, contemplating the conceptual proposals and market practices related to auditing and to the current diagnosis and the organizational model of Petrobras, so as to choose elements for comparison and analysis of such vision. The results of this research pointed in the direction of questioning the organizational value of the internal audit action, concluding that it will only be possible to continuously attain such value by means of a permanent coordination with the organization's strategic level. This is especially true if the audit action participates effectively in the process of Corporate Governance, in defining the risks, the internal control system and the measurement of corporate performance, as related to the development of the strategic plan. However, any action along these lines is still heavily impacted and limited by several aspects of culture and relationship of the organizational power as well as by the beliefs of the organization and of the body of auditors. The involvement of the auditors as employees was also considered relevant in the auditing process, by means of the participation of the audited entities in self assessment2. This procedure is still not sufficiently guaranteed by successful experiments in major organizations, considering that there is not a clear demonstration of the effective benefits of adopting this practice, as ompared to the central control, seldom shared but strongly monitored by integrated information systems. Finally, this research points to the need to renew the concept of the formation and role of the auditors in modern competitive organizations, in the face of information technology and of automation of the instrument controls of the business. Therefore, one may conclude that the trend will be toward an action aiming at the revision of formal internal control matrixes, as they are established in such systems. On the other hand, the majority of audit human resources will be increasingly deployed to the evaluation of risk and control, as related to relevant events of a more abstract nature, as in the case of those connected with the uncontrollable factors of the external environment.

Sistemas técnicos de trading no mercado de ações brasileiro : testando a hipótese de eficiência de mercado em sua forma fraca e avaliando se a análise técnica agrega valor

O objetivo deste trabalho é examinar se a análise técnica agrega valor às decisões de investimentos. Através da elaboração de intervalos de confiança, construídos através da técnica de Bootstrap de inferência amostral, e consistentes com a hipótese nula de eficiência de mercado na sua forma fraca, foram testados 4 sistemas técnicos de trading. Mais especificamente, obteve-se os resultados de cada sistema aplicado às series originais dos ativos. Então, comparou-se esses resultados com a média dos resultados obtidos quando os mesmos sistemas foram aplicados a 1000 séries simuladas, segundo um random walk, de cada ativo. Caso os mercados sejam eficientes em sua forma fraca, não haveria razão para os resultados das séries originais serem superiores aos das séries simuladas. Os resultados empíricos encontrados sugeriram que os sistemas testados não foram capazes de antecipar o futuro utilizando-se apenas de dados passados. Porém, alguns deles geraram retornos expressivos
