A comparative analysis between helicopter and seaplane for passenger transport.
2016
Purpose This study aims to develop a methodology to compare the feasibility of helicopter and seaplane regular transport of passengers towards destinations across a remote regional tourist context, where a lack of road and rail infrastructure make these alternative forms of air transport competitive. Design/methodology/approach The authors use a modal split model identifying the quota of passengers that potentially could utilize these two types of services, determined on the basis of previous studies on air transport demand. A technical analysis regarding transport supply is performed to identify the predominant features that should characterize helicopter/seaplane performances. An optimiza…
Some personal views on the current state and the future of locational analysis
1998
In this paper a group of participants of the 12th European Summer Institute which took place in Tenerife, Spain in June 1995 present their views on the state of the art and the future trends in Locational Analysis. The issues discussed include modeling aspects in discrete Location Theory, the influence of the distance function, the relation between discrete, network and continuous location, heuristic techniques, the state of technology and undesirable facility location. Some general questions are stated regarding the applicability of location models, promising research directions and the way technology affects the development of solution techniques.
From bus to tramway: Is there an economic impact of substituting a rapid mass transit system? An empirical investigation accounting for anticipation …
2018
Abstract Hedonic pricing models and price equations have been extensively used to retrieve the implicit prices of urban externalities through real estate markets. Many applications have been devoted to investigating the impact of new mass transit systems, such as rail infrastructures. However, the implementation of such infrastructures usually takes some time and markets can react with an anticipation effect that can vary according to the different development phases. Moreover, the impact may be different if it acts as a substitute to existing rapid transit services. This paper focuses on the impact of substituting bus rapid transit (BRT) for light rail transit (LRT) services, taking into a…
Exact solution of the soft-clustered vehicle-routing problem
2020
Abstract The soft-clustered vehicle-routing problem (SoftCluVRP) extends the classical capacitated vehicle-routing problem by one additional constraint: The customers are partitioned into clusters and feasible routes must respect the soft-cluster constraint, that is, all customers of the same cluster must be served by the same vehicle. In this article, we design and analyze different branch-and-price algorithms for the exact solution of the SoftCluVRP. The algorithms differ in the way the column-generation subproblem, a variant of the shortest-path problem with resource constraints (SPPRC), is solved. The standard approach for SPPRCs is based on dynamic-programming labeling algorithms. We s…
From electric mobility to hydrogen mobility: current state and possible future expansions
2020
The expansion of electric vehicles in Italy, has already started a few years ago, but some aspects prevent its expansion. Currently users prefer hybrid technology, mainly due to socio-economic factors related to initial investment and anxiety about autonomy. The aim of the document is to understand if the adoption of Fuel Cell technology can be a solution to overcome the problems of environmental pollution. The possibility to be able to use fuel cells to store electricity is very advantageous, especially on charging times that are significantly reduced. Based on the current situation and analyzing the available data, this work reports the current state of electric mobility in Italy and trie…
A One Health perspective on the issue of the antibiotic resistance
2020
For a few years now, the One Health concept has appeared to go hand in hand with the issue of antibiotic resistance as the most comprehensive and global solution. As part of a study comparing the publicization process of the links between antibiotic resistance and food in France and in the United States, this paper retraces the One Health concept's trajectory in terms of significations and (re)definitions, according to the actors adopting this approach as a viable solution. Furthermore, this paper questions the concept's take over impact in antibiotic resistance reframing as well as its expansion in terms of functioning and applicability. Within social sciences research, interest in the iss…
Democratic Principles and the Economic Branch of the European Monetary Union
2017
L'articolo si propone di indagare sul valore che i vari principi democratici enunciati nel TUE hanno nello specifico settore dell'UEM, in particolare nel pilastro della politica economica, dopo l'entrata in vigore delle riforme contenute nel Six pack e nel successivo Two Pack. Il lavoro intende in particolare rispondere a tre domande: A) le regole contenute nel six pack e nel two pack in tema di controllo democratico sono espressione di un preciso modello di controllo democratico sulle scelte di politica economica nell'ambito dell'UEM? B) E' un simile modello compatibile con i principi democratici del TUE? C) I principi democratici non rappresentativi possono compensare il minor peso che vi…
Screening of Foreign Direct Investment and the States’ Security Interests in Light of the OECD, UNCTAD and Other International Guidelines
2021
AbstractThis chapter analyses the concept of the “national security interest”, which is widely recognised as allowing a state to determine which areas of its economy are restricted or prohibited to foreign investors. This chapter seeks to identify what constitutes a threat for a state and how that threat is managed both domestically and internationally. Despite the recognition of a state’s right to take measures it considers essential to its security, there are limits. The rules established by the Organisation for Economic Co-operation and Development (OECD) and the United Nations Conference on Trade and Development (UNCTAD) and other international instruments are non-binding but can serve …
Professionalization as Status Adaptation: The Nobility, the Bureaucracy, and the Modernization of the Legal Profession in Finland
1991
In contrast to Anglo-American lines of professional development, the central agent of professionalization in many Continental countries was the state bureaucracy. However, this article proposes that an understanding of the class structure of traditional society is also needed to explain the privileged position of lawyers. An historical study of lawyers in the 19th century, after Finland was annexed by Russia, demonstrates that the legal profession provided the nobility an important medium of adaptation to the new society. The importance of the legal profession initially to the state bureaucracy, and subsequently to the nobility, explains its social prominence and its future development. An …
On some difficulties of putting in dialogue animal rights with anthropological debates: a historical view in three episodes
2018
In this paper, I try to identify the reasons why the dialogue between sociocultural anthropology and animal rights theories and movements continues to be difficult and scarce. At first sight this weakness of communication is surprising, if one looks at the amount of anthropological studies on human/animal relationships, in most cases pointing to how animals are considered in many cultures as non- human subjects or persons. For understanding the roots of this state of affairs, I compare the ways anthropologists and animal rights theorists and activists have engaged with the issue of the differences and commonalities between human beings and nonhuman animals. For this aim, I contrast the sear…
