Eurobalise-Train communication modelling to assess interferences in railway control signalling systems

The evolution of the railway sector depends, to a great extent, on the deployment of advanced railway signalling systems. These signalling systems are based on communication architectures that must cope with complex electromagnetical environments. This paper is outlined in the context of developing the necessary tools to allow the quick deployment of these signalling systems by contributing to an easier analysis of their behaviour under the effect of electromagnetical interferences. Specifically, this paper presents the modelling of the Eurobalise-train communication flow in a general purpose simulation tool. It is critical to guarantee this communication link since any lack of communication may lead to a stop of the train and availability problems. In order to model precisely this communication link we used real measurements done in a laboratory equipped with elements defined in the suitable subsets. Through the simulation study carried out, we obtained performance indicators of the physical layer such as the received power, SNR and BER. The modelling presented in this paper is a required step to be able to provide quality of service indicators related to perturbed scenarios.

Multi-victim sexual assault : a case study in rural Australia

Objective: There is a paucity of information regarding cases of multi-victim sexual assault of children. The reported incidence suggests that these cases are rare. The aim of this paper is to provide practitioners with information about effective intervention strategies arising out of the direct experience of managing a case of multi-victim sexual assault in an Australian rural community. --------- Method: A descriptive, case-report methodology summarizing the investigation and intervention in a case of multi-victim sexual assault is reported. A community based intervention arising out of the disclosures of 21 male children is described. The intervention occurred at an individual, group, and community level using a coordinated multi-disciplinary team and natural helping networks. ---------- Results: The coordination of police and welfare services increased the communication flow to victims, their families, and the community. The case also demonstrated the utility in regularly briefing political and bureaucratic authorities as well as local officials about emergent issues. Coordinating political and bureaucratic responses was essential in obtaining ongoing support and sufficient researching to enable the effective delivery of services. ---------- Conclusions: Interventions were focused at an individual, group, and community level using a coordinated multi-disciplinary team and natural helping networks. This provided a choice of services which were sensitive to the case setting. Recommendations are offered for practitioners who are confronted with similar events. While this paper describes an approach for intervening in a case of multi-victim sexual assault, further empirical research is needed to enable service deliverers to efficaciously target interventions which offer choice to victims and their families.

Study of ICT adoption for building project management in the Indian construction industry

Building project management requires effective coordination and collaboration between multiple project members. It can be achieved through real time communication flow between all. In present scenario, it can be achieved through adoption of Information and Communication Technologies (ICT). Construction industry primarily comprises small and medium enterprises (SMEs). Also, ICT adoption has been slow in the industry.---------- Research is required to assess the factors that affect ICT adoption at the three levels of industry, organization and people, with focus on SMEs. This paper discusses a component of the research undertaken to study these factors and issues in the context of Indian construction industry. A questionnaire survey was conducted and through quantitative data analysis the extent of adoption of formal Project Management processes, ICT adoption for these processes and factors including perception based factors affecting ICT adoption were studied. Results of data analysis includes identification of issues that require action at the three study levels.---------- The results can be generalized for other countries with due considerations, specifically for countries where the construction industry is similar to Indian construction industry in terms of working methodologies or for large countries.

Understanding welding practices on shipyards : an ethnographic study for designing an interactive robot welder

The aim of this ethnographic study was to understand welding practices in shipyard environments with the purpose of designing an interactive welding robot that can help workers with their daily job. The robot is meant to be deployed for automatic welding on jack-up rig structures. The design of the robot turns out to be a challenging task due to several problematic working conditions on the shipyard, such as dust, irregular floor, high temperature, wind variations, elevated working platforms, narrow spaces, and circular welding paths requiring a robotic arm with more than 6 degrees of freedom. Additionally, the environment is very noisy and the workers – mostly foreigners – have a very basic level of English. These two issues need to be taken into account when designing the interactive user interface for the robot. Ideally, the communication flow between the two parties involved should be as frictionless as possible. The paper presents the results of our field observations and welders’ interviews, as well as our robot design recommendation for the next project stage.

The application of social network analysis in the construction industry of Hong Kong

The Hong Kong construction industry is currently facing ageing problem and labour shortage. There are opportunities for employing ethnic minority construction workers to join this hazardous industry. These ethnic minority workers are prone to accidents due to communication barriers. Safety communication is playing an important role for avoiding the accidents on construction sites. However, the ethnic minority workers are not very fluent in the local language and facing safety communication problems while working with local workers. Social network analysis (SNA), being an effective tool to identify the safety communication flow on the construction site, is used to attain the measures of safety communication like centrality, density and betweenness within the ethnic minorities and local workers, and to generate sociograms that visually represent communication pattern within the effective and ineffective safety networks. The aim of this paper is to present the application of SNA for improving the safety communication of ethnic minorities in the construction industry of Hong Kong. The paper provides the theoretical background of SNA approaches for the data collection and analysis using the software UCINET and NetDraw, to determine the predominant safety communication network structure and pattern of ethnic minorities on site.

Um país, poucas vozes: estudo sobre o fluxo de informação jornalística em impressos brasileiros

Esta dissertação trata do fluxo de informações jornalísticas em impressos brasileiros, tomando como eixo diferentes regiões do Brasil. Mensuramos o nível de desequilíbrio desse fluxo entre estados com acentuadas diferenças sociais e econômicas, tomando como exemplo, a relação entre o Ceará e epicentros midiáticos como São Paulo, Rio de Janeiro e Brasília, através de quatro jornais impressos. A pesquisa operou em dois eixos. O primeiro dentro dos estudos de comunicação internacional, campo que iniciou os trabalhos pioneiros sobre os fluxos de comunicação. O segundo buscou os critérios de noticiabilidade e a égide da objetividade dentro do processo de construção da notícia. Com essa base teórica, foi possível analisar os dados e traçar um painel de como funcionam os fluxos de informação jornalística nos veículos escolhidos e a lógica temática por trás dos números.

The objective of this study is to adress the action possibilities of the Public Relations professional in management of communication between the virtual services companies and their customers – the cybernauts. For this purpose, a bibliographical research was made about the cyberspace, Internet environment, as well as the cyberculture and the on-line consumer public. It was also studied the possible areas of Public Relations's action, their work tools and means of communication with the customer, in order to verify the specificities of communication mediated by new technologies. Based on these concepts, it was possible to propose an action of this professional in the organizations called dotcom, in order to contribute to the management of the communication flow between companies and this “invisible” public, which relates virtually to the organization, establishing different modes of interaction in relation to tradicional customers, requiring different strategies of relashionsip

The coordination of care for tuberculosis control

This descriptive epidemiological study analyzed the coordination of tuberculosis (TB) patient care in primary healthcare services according to 23 patients, 16 professionals, and 17 administrators from Ribeirao Preto, Sao Paulo, using an instrument adapted to evaluate TB. According to the informants, the coordination of healthcare provided to patients under the treatment of the Tuberculosis Control Program team was considered satisfactory; however, when there is a need to refer the patient to other care units there are weak points in the coordination of healthcare, which include: interruption of communication flow; and patients' incipient participation in the care process, with a need to increase the sense of responsibility for patient care and encourage patients to become active agents in the process.

COMUNICAÇÃO ESTRATÉGICA DE IES ATRAVÉS DO HANDEBOL DE ALTO RENDIMENTO

A tese aborda como a Universidade Metodista de São Paulo (UMESP) e a Universidade de Taubaté (UNITAU) utilizam o esporte de alto rendimento como meio de divulgação estratégica. O estudo mostra qual é a relação existente entre a comunicação institucional e mercadológica das referidas IES e o handebol de alto rendimento. A tese objetiva também, apresentar as ferramentas de comunicação utilizadas por UMESP e UNITAU para divulgar suas ações de patrocínio e, por fim, avaliar o grau do fluxo de comunicação dos profissionais de comunicação e marketing das IES com gestores esportivos do handebol. A comparação entre as IES analisadas deu-se pelo uso do método de pesquisa de ‘estudos de casos múltiplos’, já a pesquisa documental e a bibliográfica foram utilizadas para a construção teórica do trabalho. Os dados dos objetos de estudo foram coletados através do uso da técnica de entrevista, estas que, adotaram a característica ‘semiestruturada’ com perguntas abertas e uso de roteiro. Concluiu-se que as universidades UMESP e UNITAU pouco exploram a imagem vitoriosa do handebol de alto rendimento que investem como meio estratégico de divulgação

Climate change in mountain regions: how local communities adapt to extreme events

This paper examines how local communities adapt to climate change and how governance structures can foster or undermine adaptive capacity. Climate change policies, in general, and disaster risk management in mountain regions, in particular, are characterised by their multi-level and multi-sectoral nature during formulation and implementation. The involvement of numerous state and non-state actors at local to national levels produces a variety of networks of interaction and communication. The paper argues that the structure of these relational patterns is critical for understanding adaptive capacity. It thus proposes an expanded concept of adaptive capacity that incorporates (horizontal and vertical) actor integration and communication flow between these actors. The paper further advocates the use of formal social network analysis to assess these relational patterns. Preliminary results from research on adaptation to climate change in a Swiss mountain region vulnerable to floods and other natural hazards illustrate the conceptual and empirical significance of the main arguments.
