Exploring the uncertainty in capacity estimation at roundabouts

2017

Abstract Purpose In gap-acceptance theory the critical and the follow-up headways have a significant role in determining roundabout entry capacities which in turn depend on circulating flow rates under a specified arrival headway distribution. Calculation considers single mean values of the gap-acceptance parameters, neglecting the inherent variations in these random variables and providing a single value of entry capacity. The purpose of this paper is to derive the entry capacity distribution which accounts for the variations of the contributing (random) variables and suggest how to consider this issue in the operational analysis of the roundabouts. Methods We performed a Monte Carlo simul…

Sustainable mobility: “exchange poles” between transport networks and urban structure

2012

An intermodal hub can be defined as a place where transportation networks are organized to facilitate intermodality between different modes. Intermodal hubs should intrinsically have an urban dimension and be globally designed as “plug flows”, being interfaces between transport networks and territory, being an element to create “urbanity”. Intermodal hubs focus technical, social, urban, transport, service aspects and they play a multi-modal, multi-service, multioperator role. Several studies highlight the need to “measure the interdependence” among the various aspects of urban problems, avoiding too specific methodologies. The increasing congestion in urban centres and urban parking problem…

Flower Roundabouts And Double-Lane Roundabouts: A Comparative Performance Analysis

2014

AbstractIn the paper, a choice criterion between flower roundabouts and double-lane roundabouts is proposed, focusing on operational benefits that can derive from one scheme over the other, and outlining a general framework for benefit-cost analysis. In order to assess operational benefits of innovative roundabouts over modern roundabouts, a comparative analysis was made. Capacity was estimated using gap-acceptance models. In detail, assuming the dichotomic shifted negative exponential distribution to model headways in circulating streams, the Hagring formula was adjusted to obtain entry capacity estimations at roundabout approaches where entering vehicles face one or two conflicting flows.…

North American entrepreneurs in Cuba: which entry mode and government affiliation strategy?

2018

Purpose To have success in newly liberalized markets, firms must have a plan of action before resources are committed. What some companies do not realize is that their own entrepreneurial orientation (EO) will dictate their strategies, and performance outcomes, in both their home market and abroad. In order to maximize firm performance in newly liberalized markets (such as Cuba), firms must be able to objectively gauge their own EO. The paper aims to discuss these issues. Design/methodology/approach Within this framework, the present paper will attempt to effectively measure the EO of decision-making managers from US companies that have an interest in entering the Cuban market. A final sam…

Entry in a Psychically Distant Market: Finnish Small and Medium-sized Software Firms in Japan

2008

This paper investigates the market entry and entry mode choice of eight small and medium-sized Finnish software firms in the Japanese market. The findings in this study reveal that, despite of the psychic distance between Finland and Japan, most of the firms entered Japan at a very early stage of their internationalization process by using direct entry modes. This was mainly due to the market size, sophisticated industry structure, and requirements for intensive cooperation with the customers during the sales process. The firms were able to overcome psychic distance by hiring local employees and western managers who already had working experience in the Japanese market. This finding indicat…

ENDOGENOUS TIMING WITH FREE ENTRY

2006

A free entry model with linear costs is considered where firms first choose their entry time and then compete in the market according to the resulting timing decisions. Multiple equilibria arise allowing for infinitely many industry output configurations encompassing one limit-output dominant firm and the Cournot equilibrium with free entry as extreme cases. Sequential entry is never observed. Both Stackelberg and Cournot-like outcomes are sustainable as equilibria however. When the number of incumbents is given, entry is always prevented, and industry output is sometimes larger than the entry preventing level.

Family business internationalization: an insight into opportunities and challenges.

2020

The theme of internationalization in family businesses is a highly topical issue that is increasingly attracting management scholars. This is because, in addition of being a particular type of business (Alcorn, 1982), they play a central role in most economies worldwide. Accounting for 65-80 percent of all the world’s firms, they generate around 70-90 percent of annual global GDP, and are the source of 50-80 percent of new jobs in most countries. Their essence lies in the close bond they have with their founders and above all, in the family’s involvement in the business ownership and management (Franco and Prata, 2019). This bond may prove to be a limit for fuelling internationalization pro…

La gerarchia delle apparenze. Moda, strumenti di controllo e potere nelle élite di antico regime

2021

L’abito è un mezzo di comunicazione che, attraverso materiali, colori e fogge particolare ben lontani dai tessuti sfarzosi e delle pietre preziose, trasmette una concezione morale e ideologica della vita . Alcuni mutamenti segnarono certamente il Cinquecento protraendosi per tutto il Seicento, periodi che la storiografia descrive spesso come secoli caratterizzati da grande mobilità sociale, fenomeno che, seppur maggiormente studiato per quanto concerne l’area inglese, è rilevabile in tutto il continente. Le trasformazioni in atto riguardavano principalmente i ceti emergenti che verosimilmente non sono interessati, almeno in un primo momento, a porre fine alla gerarchia delle apparenze, ma s…

The Medicinal Chemistry of Zika Virus

2021

Arthropod-borne viruses, also known as arboviruses, are transmitted by bites of infected mosquito or tick vectors. In this context, the Flavivirus genus is mainly transmitted by mosquitoes from the Aedes genus, being the Ae. africanus, Ae. aegypti, and Ae. Albopictus species are responsible for transmitting the Zika virus (ZIKV). It is a lipid-enveloped virus constitute of an RNA genome, which is translated into a polyprotein encoding three structural proteins {(capsid (C), membrane (M), and envelope (E)} and seven non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). Several biological targets have been identified for developing antiviral agents against ZIKV, which could pre…
