Urban transport policy transfer in central and Eastern Europe
2008
Abstract European Territorial Cooperation is one important context in which partners from across the whole of Europe meet and learn from each other. Naturally, the involvement of partners from Central and Eastern European (CEE) countries in this process is increasing as a consequence of the expansion of Europe, particularly the accession of ten new EU member states in 2004, and two more in 2007. Various examples can be found where CEE countries are seeking to catch up politically and economically by drawing lessons from policies in more developed countries. The uncertainties of policy-making in some of these countries have made policy transfer a particularly attractive option, as politician…
The Rocky Road towards Professional Autonomy : The Estonian Journalists’ Organization in the Political Turmoil of the 20th Century
2017
This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association,…
Estimating pollutant emissions based on speed profiles at urban roundabouts: A pilot study
2019
The paper describes the pilot study conducted to assess the feasibility of the empirical approach utilizing vehicle trajectory data from a smartphone app and the Vehicle-Specific Power methodology to estimate pollutant emissions at urban roundabouts. The goal of this research phase is to acquire instantaneous speed data from a sample of six roundabouts located in the road network of the City of Palermo, Italy, and quantify emissions generated by the test vehicle through the examined roundabouts. For the case studies of roundabouts acceleration events in the circulating and exiting areas contributed to about 25% of the emissions for a given speed profile. More in general, the results from th…
A model for evaluating the environmental and functional benefits of “innovative” roundabouts
2015
This study looks at the singling out of a multi-parameter criterion for choosing conventional or innovative roundabout layouts, by taking functional, environmental and economic aspects into consideration. The performances of three conventional roundabouts (with different lane number at entries and through the ring), turbo-roundabouts and roundabouts with right-turn bypass lane on all the arms (flower roundabouts) have been compared in terms of vehicle delays and pollutant (carbon dioxide, nitrogen oxides, particle pollution (PM10 and PM2.5)) emissions. By means of closed-form capacity models and with the help of COPERT IV© software, several traffic simulations have been carried out, referre…
Can crumb rubber modifier effectively replace the use of polymer- modified bitumen in asphalt mixture?
2021
Laboratory scale mechanical performances on six plant produced mixtures; three semi-dense surface courses and three dense binder courses modified with engineered crumb rubber (ECR) using the dry process are presented. The two types of mixtures produced and investigated fulfilled for the most part, the requirements of the Swiss and/or US standards regarding volumetric properties, water sensitivity and rutting. In advanced testing where no requirements exist, the dense ECR mixtures performed similar to the reference polymer modified mixtures and slightly worse for semi-dense mixtures in high temperature tests, where the binder becomes viscous in the rubber-binder composite and its ability to …
Road Safety in Brief
2019
Road safety issue has been the subject of study for many years and with each passing day transportation engineering expands this research area since it is a social matter of absolute priority.
From ship loader to port city. The case of Porto Empedocle (Da caricatore a città portuale. Il caso di Porto Empedocle)
2014
Porto Empedocle was, for many centuries, the port of the nearby city of Agrigento, imposing itself for exceptional locational qualities as maritime crossroads between all the seaports on the south coast of Sicily, albeit with ups and downs. Thanks to its strategic location, facing the north African coast and connections to the inner areas, the simple warehouse and provisioner became crucial for the economy of the island so as to be called the "most active warehouse and provisioner of the kingdom". Were performed a series of measures aimed at achieving real port facilities which would transform the original glade in functional landing place for boats of any size. Due its history, Porto Emped…
(In)Efficiencies in Latin American ETFs
2017
Este estudio evalúa empíricamente la eficiencia en la valoración de varios ETFs latinoamericanos, expresada en desviaciones de sus precios de mercado frente a los valores liquidativos subyacentes. Se cuantifican tales ineficiencias y se implementa una estrategia de negociación verificada por regresiones basadas en el CAPM y el Modelo Fama-French. Los resultados discrepan con la Hipótesis de los Mercados Eficientes y son mejor explicados por aspectos de las finanzas comportamentales. Finalmente, se examina cómo las desviaciones influyen sobre la decisión de creación o redención de ETFs, mediante un análisis de regresión logística. Los resultados evidencian que los participantes autorizados r…
The role of linkages in firm performance: evidence from southern Italy
2000
Abstract This paper estimates the probability of success of post-entry performance of new firms, using survey data from a group of southern-Italian small firms. Several factors involving inter-firm linkages contribute to success, especially production for order and subcontracting. The empirical investigation supports Hirschman’s idea on the industrialization process and positive assessments of the downsizing phenomenon in Italy.
Self-Selection into Exports: Productivity and/or Innovation?
2009
Abstract Recent research has related the firm decision to export with firm innovation activities and productivity. The aim of this paper is to disentangle the direct and indirect links through which self-selection into exports, coming both from productivity and innovation, may operate. For this purpose we use Spanish manufacturing firm data for the period 1990–2000, drawn from the Encuesta sobre Estrategias Empresariales. The main results we obtain can be summarized as follows. First, there is a self-selection into exports direct effect coming from productivity. Second, there is also a self-selection indirect effect into exports stemming from productivity to the probability of exporting thr…
