A methodology based on the Analytic Hierarchy Process for the quantitative assessment of emergency preparedness and response in road tunnels

The paper presents and discusses a methodology to judge the effectiveness of the preparedness activities in case of accidents in road tunnels by considering the system from several points of view (i.e. structural/technical, organizational/human, and contextual). Due to the different nature of the criteria involved in the assessment activity, we chose to apply the Analytic Hierarchy Process methodology (Saaty, T.L. (2006). Fundamentals of Decision Making and Priority Theory with the Analytic Hierarchy Process, RWS Publications, Pittsburgh) that allows comparing and appraising quantitatively variables that are incommensurable and that may originate from distinct and separate areas. The paper identifies the hierarchic structure necessary to measure both the performance of the emergency response system for road tunnel accidents and the weights for assessing their relative importance. Finally, the methodology is applied to a case study on a transnational road tunnel between Italy and France to show a feasible evaluation of the sensitivity of the structure to the input variables in order to find the most valuable enhancing and improving actions.     

Is tourism just another staple? A new perspective on tourism in remote regions

According to recent research, countries may have a positive image from a tourism perspective, but they may be seen as lacking from an economic or political viewpoint. As governments and destination management organisations spend large sums of money in promoting tourist attractions, the question of whether these activities also influence other aspects of a country's image becomes relevant. The objective of the research is to determine the effect of tourism promotions on the image of the country and that of the destination as two separate concepts, in the case of Israel, a country subject to continuous conflicts. A 2?×?2 quasi-experimental design is utilised to investigate the influence of tourism promotional brochures. Additionally, a comparative perspective is used to determine whether people from diverse countries and backgrounds may be affected differently by the same information. The findings confirm that tourism brochures influence not only the image of the destination, but also that of the country. These effects are found to be different for respondents from the two different countries compared. The article focuses on understanding how tourism communication strategies may also be used to improve the image of a country, with potential benefits for international marketing and international relations.     

Optimal pest control in greenhouse production of ornamental crops

In this study, we develop a conceptual bioeconomic model of floriculture production with aesthetic benefits, wherein optimal decision rules depend on an intertemporal economic objective to maximize profits subject to economic and biological processes. Necessary conditions of the model identify optimal trajectories (e.g., simultaneous, single, or cycling controls) that define decision rules and economic thresholds for profit maximizing growers producing crops with aesthetic attributes. The necessary conditions also highlight intertemporal trade‐offs between aesthetic benefits and expected future net benefits of arthropod stocks, which have important policy implications. The model is applied to the greenhouse production system of ivy geranium.     

A PEOPLE'S POLICE FOR THE TWENTY-FIRST CENTURY: A REPLY TO BLUNDELL

John Blundell's ideas for structural change could undermine the strengths of British policing. Nevertheless, there is a need for decentralisation and more local control.     

INTERNATIONAL TRADE AND GLOBAL STABILITY1

Trade liberalisation has played a critical role in advancing peace and prosperity. Differences on agriculture have been the major impediment to a future multilateral trade round. The recent agreement on agriculture at the WTO meetings in Geneva may signal a breakthrough in that sector. This article analyses the benefits of recent trade agreements and examines the prospects for future ones. It also presents an alternative framework for advancing trade, the Global Free Trade Association.     

Mini/micro computer evaluation of system features: An empirical discriminant model of software and hardware expandability,compatibility, cost-efficiency,installation and delivery

The rapid advances in technology with declining costs of hardware is expected to widen the market for computers. One of the interesting balances for vendors to achieve is keeping users happy with increases in price performance, usually with lower unit costs. One way to achieve this objective is by satisfying users and meeting their needs. Users have many different needs, however, and it may be very difficult to prioritize them since many of the needs are partially mutually exclusive. For example, the promotion of one need, low response time, would be at the expense of another need, low cost. Therefore, mini/micro vendors and users could use a model that will prioritize needs and measure how satisfied users are with specific computer systems as compared to others. Similarly, the same information may be very useful to current and future computer users for system selection. Accordingly, the main purpose of the present study is to provide vendors and users of mini/micro computers with a discriminant model. This model classifies correctly 93% of the successful systems. Thus it can be used for system selection by users and for system design by vendors.     

Volatilidad en los ingresos y en el mercado de trabajo de los jóvenes en Europa

Los autores ofrecen nuevos datos empíricos sobre la volatilidad en los ingresos y en el mercado de trabajo (incluyendo entradas y salidas del empleo) de los jóvenes en Europa durante la Gran Recesión. Los datos de EU‐SILC para el periodo 2004–2013 revelan grandes disparidades al respecto entre los países europeos. La Gran Recesión incrementó la volatilidad entre los jóvenes. Mediante un ejercicio de descomposición de la varianza se observa una mayor rotación laboral en el sur de Europa. Según un modelo de efectos fijos, un mayor nivel de prestaciones de desempleo y de protección del empleo se asocia con una reducción de la volatilidad.
