Navigation Acts and the integration of North Baltic shipping in the early nineteenth century
2017
This article discusses how Navigation Acts affected shipping and commodity trade from and to the Northern Baltic during the early nineteenth century. We use Finnish shipping and foreign trade as an example of trade integration at the time. Finland can be used as a ‘laboratory case’ to study the importance of the Navigation Acts, as the eastern part of the area followed Russian legislation without the Navigation Act to restrict shipping to domestic vessels, while the western part followed Swedish legislation with strict protection through the Swedish version of the Act ( Produktplakat). The article argues that the role played by foreign vessels in shipments of Finnish export goods was far m…
Bi-objective multi-layer location–allocation model for the immediate aftermath of sudden-onset disasters
2019
International audience; Locating distribution centers is critical for humanitarians in the immediate aftermath of a sudden-onset disaster. A major challenge lies in balancing the complexity and uncertainty of the problem with time and resource constraints. To address this problem, we propose a location–allocation model that divides the topography of affected areas into multiple layers; considers constrained number and capacity of facilities and fleets; and allows decision-makers to explore trade-offs between response time and logistics costs. To illustrate our theoretical work, we apply the model to a real dataset from the 2015 Nepal earthquake response. For this case, our method results in…
Managing in-country transportation risks in humanitarian supply chains by logistics service providers: Insights from the 2015 Nepal earthquake
2017
International audience; Humanitarian supply chains (HSCs) play a central role in effective and efficient disaster relief operations. Transportation has a critical share in HSCs and managing its risks helps to avoid further disruptions in relief operations. However, there is no common approach to or culture of risk management that its applicability has been studied through recent cases. This paper incorporates an empirical research design and makes a threefold contribution: first, it identifies in-country transportation risks during Nepal response. Second, we evaluate afore identified risks through an expert driven risk assessment grid. Third, we use our field data to study how some humanita…
SUP&R DST: SUstainable pavement & railways decision support tool
2018
6th International Symposium on Life-Cycle Civil Engineering, IALCCE 2018; Ghent; Belgium; 28 October 2018 through 31 October 2018, GHENT, BELGIQUE, 28-/10/2018 - 31/10/2018; In order to help the decisions makers to efficiently address eco-design for transport infrastructure technologies, a decision support toll (DST) was developed in the scope of the training-through-research programme Sustainable Pavements & Railways Initial Training Network (www.superitn.eu). It consists of a computational platform that implements a conceptual framework developed to quantify sustainability. It comes with a set of sustainability indicators tailored to both road and railway systems as well as several ob…
A complex network analysis of inbound tourism in Sicily
2019
In this article, the complex dynamics of inbound tourism in Sicily is analyzed for the period 1998–2017. The horizontal visibility graph algorithm is used to transform the overnight stays' time series into a network whose topology is investigated by standard network analysis. Discontinuities in the domestic and international tourism demand were identified in order to detect signals of change and the timing of the directional change in tourism growth. The network degree distribution confirms the complex structure of the destination and reveals the random and thus more unpredictable nature of the international tourism demand in Sicily, compared with a more stable domestic segment. Some policy…
The impact of globalization on regional development and competitiveness: cases of selected regions
2019
International audience; The objective of this study is to conduct an analysis of regional development and competitiveness in the EU and Latvia under current conditions of economic globalization. This paper makes an attempt to evaluate a theory of regional development and regional competitiveness concept in relation to regional competitiveness in the light of current global economic changes. The authors emphasise that the regional development is based on competitive advantages, which has been a subject of fundamental research by Michal Porter and that serves as a basis for the current scientific methodology to assess competitiveness of regions and countries. The authors support a view of man…
Tourism-led growth hypothesis in the top ten tourist destinations: New evidence using the quantile-on-quantile approach
2017
This paper examines the empirical validity of the tourism-led growth hypothesis in the top ten tourist destinations in the world (China, France, Germany, Italy, Mexico, Russia, Spain, Turkey, the United Kingdom, and the United States) using the quantile-on-quantile (QQ) approach and a new index of tourism activity that combines the most commonly used tourism indicators. This methodology, recently introduced by Sim and Zhou (2015), provides an ideal framework with which to capture the overall dependence structure between tourism development and economic growth. The empirical results primarily show a positive relation between tourism and economic growth for the ten countries considered with s…
A new index for measuring seasonality: A transportation cost approach
2017
Abstract Seasonal fluctuations characterize many natural and social phenomena. Although the causes and impacts of seasonality are generally well documented in different study contexts, and many methods for isolating the seasonal component have been developed, considerably less attention has been paid to the measurement of the degree of seasonality. After reviewing the main indices used for measuring seasonality in different study contexts, we will propose a new approach in which seasonality is evaluated on the basis of the solution of a transportation problem. By considering the interdisciplinary nature of seasonal phenomena, the topic of measuring seasonality merits attention from a wide v…
Urban sprawl and health outcome associations in sicily
2019
Urban sprawl has several negative impacts on the environment, the economy, and human health. The main objective of this work was to formulate and validate a sprawl/compactness index for Sicilian municipalities and evaluate its association with health outcomes. An ecological study was conducted with 110 municipalities in Sicily, Italy. Principal component analysis was adopted to create the sprawl/compactness Sicilian index, and linear regression analysis was used to evaluate the association between the sprawl index and health outcomes. More variance of the new sprawl index was explained by the working factor, followed by density, surface extension, and land use mix. When validating the index…
Do shippers’ characteristics influence port choice criteria? Capturing heterogeneity by using latent class models
2022
Abstract This paper focuses on the study of Spanish ceramic tile exporters' port choice criteria, an industry that is characterized by a low unit value index. Thus, transport costs highly influence the competitiveness of their products in international markets, representing a relatively high percentage of the value of the shipment. It is therefore critical for this type of industry to have access to efficient door-to-door maritime chains. Determinants of port choice are analysed through a latent class model allowing to link class membership to specific characteristics of the shippers and their shipments such as the size of the company, the value of the shipment, the destination market and t…
