Percepción del riesgo biológico en el personal asistencial en un hospital de alta complejidad de la ciudad de Bogotá.

OBJETIVOS: Identificar la percepción del riesgo biológico de los trabajadores asistenciales del Hospital Central de la Policía Nacional en la ciudad de Bogotá. METODOS: se realizó un estudio analítico de corte transversal para describir la percepción acerca del riesgo biológico en 159 trabajadores asistenciales de un hospital de alta complejidad en la ciudad de Bogotá (Colombia), la información se recolectó por medio de la utilización de la encuesta validada nota técnica 578 (Portell M, Solé M, 2001). Se realizó la caracterización de la población por variables de sexo, edad, tiempo de experiencia y servicio al cual pertenece y se promediaron las respuestas obtenidas para cada ítem encuestado, obteniendo una clasificación para cada dimensión de percepción de riesgo baja (1 a 3), media (4 a 5) o alta (6 a 7). Resultados: De los 159 trabajadores asistenciales encuestados el 80.4% eran de género femenino, el 22.2% pertenecían al servicio de urgencias, el 16,5% al servicio de medicina interna y el 9.5% al servicio de pediatría, de los encuestados el 62.9% fueron auxiliares de enfermería, el 21,4% enfermeras jefes y el 6.9% médicos. Se obtuvo una percepción de riesgo alta (media aritmética mayor de 5) para todas las variables incluidas en la encuesta, demostrando conocimiento de todo el personal acerca de la alta exposición a accidentes de tipo biológico. No se encontró asociación entre la labor desempeñada y la percepción del riesgo biológico, sin embargo, se encontró una asociación entre el tiempo de experiencia del trabajador y una disminución en la magnitud del riesgo percibido (Chi cuadrado de asociación, p=0.042). Conclusiones: Los trabajadores asistenciales identifican la magnitud del riesgo biológico al que se encuentran expuestos en sus labores del día a día, sin embargo, es necesaria una mayor participación por parte del personal directivo y de los responsables de la prevención en temas de reacción ante accidentes y en la valoración del riesgo, especialmente en personas que llevan mucho tiempo desempeñando la labor.

A segurança nas actividades de ar livre e de aventura

RESUMO: A temática da segurança é uma das preocupações principais da sociedade actual. Dentro deste tema que é estudado nas mais diversas áreas da sociedade, a sua aplicação nas actividades de ar livre e de aventura é uma questão fundamental. As atividades de ar livre e de aventura caracterizam-se por um meio incerto, onde é importante o domínio das técnicas e aplicação das regras de segurança. É certo que cada vez existem mais praticantes das actividades de ar livre e de aventura, o aumento dos praticantes faz-se ao nivel desportivo, recreativo ou de lazer. O turismo de aventura está em crescimento em todo o mundo ocidental, sendo cada vez mais importante estudar o risco e a segurança nestas actividades. Sabemos que um dos locais mais importantes para trabalhar o risco e a segurança é ao nivel da escola, sendo o objectivo deste estudo verificar se a preocupação com a segurança está presente nos programas leccionados. Este estudo procurou identificar vários modelos de gestão de risco e verificar se estes seriam abordados nos três programas. Todas as entidades falam em segurança, diminuição do risco mas é importante clarificar o conceito e estudar se existe uma efectiva preocupação com esta questão. Este estudo procura enquadrar e discutir vários modelos de gestão de risco, verificando se essa existência está presente nos programas de EF, nos do Desporto Escolar e nos da ULHT. ABSTRACT: Security is a major concern of nowadays society. Within this subject that is studied in various areas of society, its applications in outdoor activities and adventure are a key issue. Outdoor activities and adventure are characterized by an uncertain environment, where it is important to master the techniques and application of safety rules. It is true that every day there are more people practicing outdoor activities and adventure, this increase is at the level of sport, recreation or leisure. Adventure tourism is growing throughout the Western world, and as so, it is increasingly important to study the risk and safety in these activities. We know that one of the most important places to study risk and safety is at school level, aiming to verify if security is present in the taught programs. This study sought to identify several models of risk management and verify if these would be addressed in the three programs. António Pedro Raposo Marques Vidal A SEGURANÇA NAS ACTIVIDADES DE AR LIVRE E DE AVENTURA 6 Many entities talk about safety and risk reduction, but it is important to clarify the concept and it is important to study if there is a real concern with this issue. This study seeks to encompass and discuss various models of risk management, ensuring that they are present in the programs of Physical Education in Sports School and the ULHT.

Operations on Risk Variables

In the article the author considers and analyzes operations and functions on risk variables. She takes into account the following variables: the sum of risk variables, its product, multiplication by a constant, division, maximum, minimum and median of a sum of random variables. She receives the formulas for probability distribution and basic distribution parameters. She conducts the analysis for dependent and independent random variables. She propose the examples of the situations in the economy and production management of risk modelled by this operations. The analysis is conducted with the way of mathematical proving. Some of the formulas presented are taken from the literature but others are the permanent results of the author.

Learning from risks: A tool for post-project risk assessment

Risk management (RM) comprises of risk identification, risk analysis, response planning, monitoring and action planning tasks that are carried out throughout the life cycle of a project in order to ensure that project objectives are met. Although the methodological aspects of RM are well-defined, the philosophical background is rather vague. In this paper, a learning-based approach is proposed. In order to implement this approach in practice, a tool has been developed to facilitate construction of a lessons learned database that contains risk-related information and risk assessment throughout the life cycle of a project. The tool is tested on a real construction project. The case study findings demonstrate that it can be used for storing as well as updating risk-related information and finally, carrying out a post-project appraisal. The major weaknesses of the tool are identified as, subjectivity of the risk rating process and unwillingness of people to enter information about reasons of failure.

The SAFE FOODS framework for improved risk analysis of foods

Three main changes to current risk analysis processes are proposed to improve their transparency, openness, and accountability. First, the addition of a formal framing stage would allow interested parties, experts and officials to work together as needed to gain an initial shared understanding of the issue, the objectives of regulatory action, and alternative risk management measures. Second, the scope of the risk assessment is expanded to include the assessment of health and environmental benefits as well as risks, and the explicit consideration of economic- and social-impacts of risk management action and their distribution. Moreover approaches were developed for deriving improved information from genomic, proteomic and metabolomic profiling methods and for probabilistic modelling of health impacts for risk assessment purposes. Third, in an added evaluation stage, interested parties, experts, and officials may compare and weigh the risks, costs, and benefits and their distribution. As part of a set of recommendations on risk communication, we propose that reports on each stage should be made public.

A note on estimating market–based minimum capital risk requirements: a multivariate GARCH approach

Internal risk management models of the kind popularized by J. P. Morgan are now used widely by the world’s most sophisticated financial institutions as a means of measuring risk. Using the returns on three of the most popular futures contracts on the London International Financial Futures Exchange, in this paper we investigate the possibility of using multivariate generalized autoregressive conditional heteroscedasticity (GARCH) models for the calculation of minimum capital risk requirements (MCRRs). We propose a method for the estimation of the value at risk of a portfolio based on a multivariate GARCH model. We find that the consideration of the correlation between the contracts can lead to more accurate, and therefore more appropriate, MCRRs compared with the values obtained from a univariate approach to the problem.

The use of risk registers by project managers

The construction industry is widely recognised as being inherent with risk and uncertainty. This necessitates the need for effective project risk management to achieve the project objectives of time, cost and quality. A popular tool employed in projects to aid in the management of risk is a risk register. This tool documents the project risks and is often employed by the Project Manager (PM) to manage the associated risks on a project. This research aims to ascertain how widely risk registers are used by Project Managers as part of their risk management practices. To achieve this aim entailed interviewing ten PMs, to discuss their use of the risk register as a risk management tool. The results from these interviews indicated the prevalent use of this document and recognised its effectiveness in the management of project risks. The findings identified the front end and feasibility phases of a project as crucial stages for using risk registers, noting it as a vital ingredient in the risk response planning of the decision making process. Moreover, the composition of the risk register was also understood, with an insight into how PMs produce and develop this tool also ascertained. In conclusion, this research signifies the extensive use of the risk register by PMs. A majority of PMs were of the view that risk registers constitute an essential component of their project risk management practices. This suggests a need for further research on the extent to which risk registers actually help PMs to control the risks in a construction project, particularly residual risks, and how this can be improved to minimize deviations from expected outcomes.

Private climate change reporting: an emerging discourse of risk and opportunity?

Purpose – This paper aims to explore the nature of the emerging discourse of private climate change reporting, which takes place in one-on-one meetings between institutional investors and their investee companies. Design/methodology/approach – Semi-structured interviews were conducted with representatives from 20 UK investment institutions to derive data which was then coded and analysed, in order to derive a picture of the emerging discourse of private climate change reporting, using an interpretive methodological approach, in addition to explorative analysis using NVivo software. Findings – The authors find that private climate change reporting is dominated by a discourse of risk and risk management. This emerging risk discourse derives from institutional investors' belief that climate change represents a material risk, that it is the most salient sustainability issue, and that their clients require them to manage climate change-related risk within their portfolio investment. It is found that institutional investors are using the private reporting process to compensate for the acknowledged inadequacies of public climate change reporting. Contrary to evidence indicating corporate capture of public sustainability reporting, these findings suggest that the emerging private climate change reporting discourse is being captured by the institutional investment community. There is also evidence of an emerging discourse of opportunity in private climate change reporting as the institutional investors are increasingly aware of a range of ways in which climate change presents material opportunities for their investee companies to exploit. Lastly, the authors find an absence of any ethical discourse, such that private climate change reporting reinforces rather than challenges the “business case” status quo. Originality/value – Although there is a wealth of sustainability reporting research, there is no academic research on private climate change reporting. This paper attempts to fill this gap by providing rich interview evidence regarding the nature of the emerging private climate change reporting discourse.

Foreign direct investment in high-risk environments: an historical perspective

Since the banking crisis of 2008 the global economy is perceived as riskier than before. Firms that cannot manage risks have withdrawn from countries in which they previously invested. These problems are not new. For centuries firms have invested in risky foreign environments, and many of them have succeeded. This paper reviews the risk management strategies of foreign investors. Using archival evidence and secondary sources it distinguishes the different types of risks that investors face and the different strategies by which risks can be managed. It investigates which strategies are used to manage which types of risk.

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 word of caution on calculating market-based minimum capital risk requirements

This paper demonstrates that the use of GARCH-type models for the calculation of minimum capital risk requirements (MCRRs) may lead to the production of inaccurate and therefore inefficient capital requirements. We show that this inaccuracy stems from the fact that GARCH models typically overstate the degree of persistence in return volatility. A simple modification to the model is found to improve the accuracy of MCRR estimates in both back- and out-of-sample tests. Given that internal risk management models are currently in widespread usage in some parts of the world (most notably the USA), and will soon be permitted for EC banks and investment firms, we believe that our paper should serve as a valuable caution to risk management practitioners who are using, or intend to use this popular class of models.

Paying for long-term performance: restructuring bankers’ pay for risk regulation

The purpose of this paper is to propose hybrid capital securities as a new approach to compensation for senior bank executives and risk-takers instead of cash or equity-based compensation currently adopted by the industry. The global financial turmoil indicated that misaligned pay-for-performance compensation arrangements encouraged management short-termism and rewarded excessive risk-taking behaviour in Anglo-Saxon system. Rather than regulating specific instruments and processes, we believe that it is much more efficient to overhaul the compensation scheme to align it with risk management and governance. This empirical paper investigates the European hybrid market by employing data from the Merrill Lynch Global Index System from 2000 to 2010. Our paper contributes to both literature and practices by designing a structured scheme to tie the executive’s interests to long-term performance of the bank, the goal of regulators and the economy at large which consequently reduce the probability of future bank failures.
