Seismic vulnerability assessment of historical urban centres: case study of the old city centre of Faro,Portugal

The necessity of implementing seismic vulnerability assessment procedures to the Portuguese building stock has become urgent as recent predictions indicate the possibility of the occurrence of an earthquake similar to the well-known 1755 Lisbon earthquake within the next 50 years. Obviously, at first instance, large-scale procedures should be used rather than more extensive and accurate methodologies suited for individual buildings assessment. Moreover, it is fundamental to operate in the most vulnerable areas in our built environment, typically, the historical urban centres. As it is recognised, it is within these areas, that old masonry buildings are generally concentrated, being both the most representative and vulnerable constructive typology. Comprising 354 buildings, the case study of the old city centre of Faro is herein presented aiming at analysing and evaluating the seismic vulnerability of its old masonry building stock. In order to achieve these objectives, a vulnerability-index-based methodology was used for the assessment of the seismic vulnerability of the old masonry buildings belonging to the historical centre of Faro (Ribeirinha area) carried out through detailed inspection and survey. The results obtained were analysed using a geographical information system tool. The integration of such vulnerability and loss results represents a valuable tool for city councils and/or regional authorities to plan interventions, on the basis of a global view of the site under analysis, leading this way to more accurate and comprehensive risk mitigation strategies which comply with the requirements of safety and emergency planning. The application of this large-scale scoring methodology has confirmed moderate-to-high values for the vulnerability of this particular area, which combined with its high seismicity, may be quite alarming.

Regulation and cost efficiency in the European railways industry

The objective of this article is to analyze European railways’ incentives to improve efficiency in the recent liberalization context. We build and estimate a structural model accounting for regulatory pressures faced by the firms. Our model includes demand equations, capacity constraints and a cost function, in which are specified an exogenous technical efficiency component and an endogenous cost reducing effort parameter. We find a significant positive effect of implementing the reforms on cost reducing activities, and a smaller cost of effort for firms choosing a more advanced separation of infrastructure from operation activities.     

Ambidextrous leadership,paradox and contingency: evidence from Angola

Abstract

The study departs from two assumptions. First, it considers that organizations, their leaders and the HRM function are inherently paradoxical and that, in that sense, dealing with paradox is a necessary component of the leadership process which requires ambidexterity capabilities. Second, it explores whether the paradoxes of leadership may manifest differently in different contexts. We explore the emergence of paradox in the leadership of Angolan organizations. Angola is an economy transitioning from a centrally planned to a market mode, and this makes it a rich site for understanding the specificities of ambidextrous paradoxical processes in an under-researched, ‘rest of the world’, context. The findings of our inductive study led to the emergence of four interrelated paradoxes and highlight the importance of ambidextrous paradoxical work as a HRM contingency.     

A risk management model for research on expatriates in hostile work environments

Abstract

Although much has been written about the causes of expatriate adjustment, more research is needed on managing the fear and anxiety experienced when expatriates work in hostile environments. The perceived risks of terrorism, kidnapping, crime, and civil unrest can have negative effects on the performance of expatriates and the organizations that employ them. While research has begun to examine expatriates’ stress in hostile environments, there is comparatively little research on the effectiveness of management practices that can reduce such stress. We integrate the expatriate adjustment, psychological contract, and risk management literature to develop a model that can guide efforts to reduce environmental stress and its negative effect on expatriate adjustment. Specifically, we build on recent work by Bader and colleagues to develop propositions to guide future research with the aim of improving the conditions of expatriates working in hostile environments.

Socioeconomic status or noise? Tradeoffs in the generation of school quality information

This paper calculates a time series of simple, standard measures of schools' relative performance. These are drawn from a 1997–2004 panel of Chilean schools, using individual-level information on test scores and student characteristics for each year. The results suggest there is a stark tradeoff in the extent to which rankings generated using these measures: i) can be shown to be very similar to rankings based purely on students' socioeconomic status, and ii) are very volatile from year to year. At least in Chile, therefore, producing a meaningful ranking of schools that may inform parents and policymakers may be harder than is commonly assumed.     

Weak cognitive image of cultural tourism destinations

The current study aims to take an in-depth look at the perceived image of an inland cultural tourism destination. This destination has traditionally had a weak image, making it important to study the components of this image and the factors influencing it in order to identify the best strategies for improving the destination’s positioning with respect to its image. This research is part of the ATLAS Cultural Tourism Research Project, which focuses on the image of tourist destinations. The basic questionnaire prepared by ATLAS and applied in a number of different countries is the key element of the survey. The results obtained show the different influences of factors such as information sources (distinguishing between induced, organic and autonomous sources), previous visits to the destination and the places visited during the tourist’s stay on the overall image of the city. This research will help public institutions to project the image of destinations in their target markets using precise information channelled through the appropriate media. In global terms we try to contribute to the study of factors influencing image formation in the case of inland cities not yet on the tourist map, but whose potential resources could make them obvious cultural tourism destinations. From this perspective, the influence of cognitive attributes in forming the image, as well as the atmosphere the tourist experiences in the city as a psychological attribute, have been studied.     

Customer Satisfaction,Competition, and Firm Performance: An Empirical Investigation

We conduct two empirical studies to test two hypotheses: (1) rivals' customer satisfaction increases a firm's own customer satisfaction; and (2) rivals' customer satisfaction reduces a firm's sales. Study One uses a panel dataset of annual store‐level customer satisfaction data from a supermarket chain for the periods 1998–2001. Study Two considers a range of industries by using a panel dataset of brand‐level customer satisfaction ratings from the American Customer Satisfaction Index spanning the periods 1994–2003. Results from both studies provide support for our hypotheses. Copyright © 2013 John Wiley & Sons, Ltd.     

Tracking the US business cycle with a singular spectrum analysis

In this paper we resort to singular spectrum analysis to disentangle the US GDP into several underlying components of interest. The business cycle indicator yielded through this method is shown to bear a resemblance with band-pass filtered output, and our results suggest it possesses better revision performance than other commonly applied filters.
