    A battery of questionnaires to assess psychosocial risk factors at work was developed in 2010 in response to Resolution 2646 created by the Colombian Ministry of Social Protection. However, this battery presents some theoretical and practical limitations. A new battery of instruments has been designed and validated that includes instruments and risk indicators of the demand-control-social support and the effort-reward imbalance models. Other factors, not included in these models, but that Resolution 2646 suggests should be assessed, have also been added, and with this additional information, the new battery allows us to also calculate a “global indicator” of demand, control, and social support; family and social risk conditions, coping and personality; and health and wellbeing. The new battery was administered to a sample of 16,095 workers from different occupations and representative Colombian regions. An analysis of the various domains indicates that internal consistency of the various scales is high. The new battery has the following properties: it is simple to use in paper format or when administered by computer, it enables comparison between occupations, it offers unified scores for each variable, and provides information to assess the risk factors suggested by Resolution 2646. In addition, it will make it possible to compare the results obtained when analyzing Colombian workers with those obtained from studies of workers from other countries.Em 2010, desenvolveu-se uma bateria de instrumentos para avaliar fatores psicossociais trabalhistas de risco para a saĂșde, em resposta Ă  Resolução 2 646 do MinistĂ©rio da Proteção Social da ColĂŽmbia. Contudo, esta conta com algumas limitaçÔes que, a partir da construção e da validação de uma nova bateria, neste estudo se pretendem superar. AlĂ©m disso, a nova bateria oferece recursos adicionais para a avaliação desses fatores: a presente bateria incorpora os instrumentos e os indicadores centrais dos modelos demanda-controle-apoio social e desiquilĂ­brio esforço-recompensa e os fatores internos do trabalho nĂŁo considerados nesses modelos, mas que a Resolução considera necessĂĄrios, mediram-se com testes preexistentes ou desenvolvidos pelos autores. Com os dados coletados, Ă© possĂ­vel calcular indicadores globais de demanda, controle e apoio social; alĂ©m de condiçÔes familiares e sociais de risco, enfrentamento, personalidade e indicadores de saĂșde e bem-estar. Para a validação, a bateria foi aplicada a uma amostra de 16 095 trabalhadores de diferentes cargos e municĂ­pios colombianos. As anĂĄl i ses de consistĂȘncia interna e validade permitem afirmar que a bateria Ă© simples de aplicar em papel ou digital, permitirĂĄ comparar cargos, obter pontuaçÔes unificadas por variĂĄvel, oferecer um diagnĂłstico de um nĂșmero importante das variĂĄveis sugeridas na Resolução bem como permitirĂĄ comparar os resultados dos trabalhadores colombianos com os de outros paĂ­ses.

    Limits and opportunities of risk analysis application in railway systems

    Get PDF
    Risk Analysis is a collection of methods widely used in many industrial sectors. In the transport sector it has been particularly used for air transport applications. The reasons for this wide use are well-known: risk analysis allows to approach the safety theme in a stochastic - rather than deterministic - way, it forces to break down the system in sub-components, last but not least it allows a comparison between solutions with different costs, introducing de facto an element of economic feasibility of the project alternatives in the safety field. Apart from the United Kingdom, in Europe the application of this tool in the railway sector is relatively recent. In particular Directive 2004/49/EC (the "railway safety directive") provides for compulsory risk assessment in relation to the activities of railway Infrastructure Managers (IMs) and of Railway Undertakings (RUs). Nevertheless the peculiarity of the railway system - in which human, procedural, environmental and technological components have a continuous interchange and in which human responsibilities and technological functions often overlap - induced the EC to allow wide margins of subjectivity in the interpretation of risk assessment. When enacting Commission Regulation (EC) No 352/2009 which further regulates this subject, a risk assessment is considered positive also if the IM or RU declare to take safety measures widely used in normal practice. The paper shows the results of a structured comparative analysis of the rail sector and other industrial sectors, which illustrate the difficulties, but also the opportunities, of a transfer towards the railway system of the risk analysis methods currently in use for the other systems

    Integrating security and usability into the requirements and design process

    According to Ross Anderson, 'Many systems fail because their designers protect the wrong things or protect the right things in the wrong way'. Surveys also show that security incidents in industry are rising, which highlights the difficulty of designing good security. Some recent approaches have targeted security from the technological perspective, others from the human–computer interaction angle, offering better User Interfaces (UIs) for improved usability of security mechanisms. However, usability issues also extend beyond the user interface and should be considered during system requirements and design. In this paper, we describe Appropriate and Effective Guidance for Information Security (AEGIS), a methodology for the development of secure and usable systems. AEGIS defines a development process and a UML meta-model of the definition and the reasoning over the system's assets. AEGIS has been applied to case studies in the area of Grid computing and we report on one of these

    Corporate environmental assessment by a bank lender : a social constructionist perspective

    Get PDF
    Over the last decade evidence has emerged which suggests that lenders are considering environmental impact of corporate borrowers as part of their lending decisions. Environmental consideration by lenders may considerably influence the level of financial support available for economic growth and environmemntal management. The primary aim of this research project is to examine the development and use of corporate environmental assessment techniques by members of a commercial lending bank. The research will build upon previous findings that highlight the influences of culture upon bank members perception of environmental credit risks. Specific emphasis will be placed on evaluating the role of mechanisms for the communiaction of bank policy. These will be analysed to find out how and why corporate environmental performance considerations shape the lending process. Research will be undertaken in the form of a case study facilitated by Lloyds TSB Group plc. Analysis will centre on an evaluation of the rationalities for environmental assessment displayed by bank members and their justification for the application of specific environemnatal assessment techniques. The findings are expected to be of direct practical benefit to bank lending officers and others interested in lending processes and/or corporate environmental assessment techniques

    How Banks Construct and Manage Risk: A Sociological Study of Small Firm Lending in Britain and Germany

    Get PDF
    This paper analyses the role of banks in financing SMEs in Britain and Germany. It applies a sociological institutionalist approach to understand how banks construct and manage risk, relating to SME business. The empirical analysis is based on the results of a comparative survey of a sample of British and German banks and also refers to statistical material produced by the banks themselves. The paper concludes that, even though bank- firm relations are still deeply embedded in national institutional frameworks, some tendencies towards convergence can also be observed, particularly among commercial banks from the two countries. These flow from both internationalisation and from the political influence of the EU.Bank Lending; SMEs; Britain; Germany

Mit Hilfe eines soziologisch institutionellen Ansatzes wird der Frage nachgegangen, wie Banken Risiken bei der Kreditvergabe an KMU konstruieren und managen. Die empirische Studie basiert auf Ergebnissen einer vergleichenden Befragung von Bankmanagern in einer Stichprobe von britischen und deutschen Banken sowie auf statistischen Angaben der Banken. Die Ergebnisse zeigen, dass Beziehungen zwischen Banken und KMU zwar nach wie vor in nationale institutionelle Rahmenbedingungen eingebettet sind. Zugleich fĂŒhren aber Internationalisierung und politische EinflĂŒsse der EuropĂ€ischen Union auch zu einer partiellen AnnĂ€herung zuvor unterschiedlicher Modelle, und zwar insbesondere was die Praktiken kommerzieller Banken in beiden LĂ€ndern betrifft.

    SMEs, electronically-mediated working and data security: cause for concern?

    Get PDF
    Security of data is critical to the operations of firms. Without the ability to store, process and transmit data securely, operations may be compromised, with the potential for serious consequences to trading integrity. Thus the role that electronically-mediated working plays in business today and its dependency on data security is of critical interest, especially in light of the fact that much of this communication is based on the use of open networks (i.e. the Internet). This paper discusses findings from a 'WestFocus' survey on electronically-mediated working and telework amongst a sample of SMEs located in West London and adjacent counties in South-Eastern England in order to highlight the problems that such practice raises in terms of data security. Data collection involved a telephone survey undertaken in early 2006 of 378 firms classified into four industrial sectors ('Media', 'Logistics', 'Internet Services' and 'Food Processing'). After establishing how ICTs and the Internet are being exploited as business applications for small firms, data security practice is explored on the basis of sector and size with a focus on telework. The paper goes on to highlight areas of concern in terms of data security policy and training practice. Findings show some sector and size influences.WestFocus* under the Higher Education Innovation Fund (HEIF 2

    A sector analysis for RFID technologies: fundamental and technical analysis for financial decision making problems

    Get PDF
    Automatic identification technologies have been used in a wide range of applications for reducing the amount of time and labor needed to input data and improving data accuracy. As an important automatic identification technology, radio frequency identification (RFID) technologies allow contactless reading and these technologies are particularly successful in manufacturing and other environments where traditional identification technologies such as bar codes can not perform well. By integrating the RFID technology into their business models, companies may save time, lower labor cost, improve products quality and provide better service. RFID is the wireless technology that uses RF communication to identify, track and manage objects and collect and store data. RFID technology enables companies to develop applications that create value by tracking and identifying objects, animals or people. Business applications of RFID technology can be seen in areas such as manufacturing, supply chain management, software integration, security systems, asset tracking and many others. RFID technology was predicted to be one of the “top ten” technologies in 2004 by CNN. Although, the RFID market is less than five years old, it has been applied to many different industries, from retail industry to logistics, or from healthcare to service business industry – and it is still growing. Particularly, RFID has fundamental influences on today's retailing and supply chain management for applications like asset tracking the inventory control and management. RFID technology also finds major application in mobile phones and is widely used in toll collection of highways, for payments in restaurants, vending machines, retail and parking lots. There are a wide range of RFID systems currently being used or being developed. Examples to these systems include but not limited to the following; automatic vehicle and personnel access control for security (Simpson, 2006), airport passenger and baggage tracking (Ferguson, 2006), tracing blood for cutting down errors such as giving patients wrong blood types (Ranger, 2006), payment process systems (Ramachandran, 2006), production control in manufacturing (Liu & Miao, 2006), transfusion medicine (Knels, 2006) real-time inventory control by automated identification of items in warehouses, tracking and management of physical files, tracking of books in the libraries (Shadid, 2005). For some other applications, interested reader is referred to (Finkenzeller, 2003; Smith, 2004). RFID solution providers claim that their technology and solutions bring significant benefits and have valuable advantages in practice. As new RFID solutions being developed and more RFID tags and equipments being used, these solutions will become more cost effective and RFID businesses are expected to grow rapidly. Since RFID is fairly new, it’s difficult to measure resulting sales increases or heightened customer satisfaction quotients. On the other hand, according to IDC estimation (IDC is a subsidiary of International Data Group, a leading technology media, research, and events company and provider of market intelligence, advisory services, and events for the information technology, telecommunications, and consumer technology markets), companies in the retail sector will spend nearly 1.3billiononRFIDintheirsupplychainoperationsin2008,comparedtoabout1.3 billion on RFID in their supply chain operations in 2008, compared to about 91.5 million in 2003 which corresponds to annual growth rate of 70 percent. In a similar look; the Wireless Data Research Group projected that the global market for RFID increased from 1billionin2003to1 billion in 2003 to 3 billion in 2007 (Asif & Mandviwalla, 2005). There are two major drivers of this growth. The first one is the adoption of RFID technology by major retailers and government agencies. The second one is the reduction in the price of RFID tags, readers, and IT systems required to deploy RFID. Given the huge potential of RFID technology, there has been a huge emergence of RFID specialty companies and the development of RFID practices within many market-leading companies. Due to huge emergence, it is desirable to make a sector analysis. In this study, we perform a sector analysis for RFID technologies for researchers and analysts. We investigate public RFID companies traded on the stock exchange markets, summarize their financial performance, describe their RF products, services, and applications, and perform fundamental and technical analysis
