TOURISM POLICY IN LATVIA - FROM A TOP-DOWN TO A COLLABORATIVE APPROACH

2020

In 2019, Latvia drafted a National Development Plan [NDP 2027] for the next period, which also comprises actions for the development of the tourism sector. Unlike previous practices, approaches to drafting a common plan and developing and implementing tourism policy have changed significantly. The aim of the research is to describe the process of developing a tourism development plan, analyse the use of the latest planning and policy implementation approaches and evaluate the framework of the plan. A qualitative research strategy - a case study was used. The main research methods are document analysis, in-depth interviews and participatory observations. The process of drafting a new tourism…

The mixed general routing polyhedron

2003

[EN] In Arc Routing Problems, ARPs, the aim is to find on a graph a minimum cost traversal satisfying some conditions related to the links of the graph. Due to restrictions to traverse some streets in a specified way, most applications of ARPs must be modeled with a mixed graph. Although several exact algorithms have been proposed, no polyhedral investigations have been done for ARPs on a mixed graph. In this paper we deal with the Mixed General Routing Problem which consists of finding a minimum cost traversal of a given link subset and a given vertex subset of a mixed graph. A formulation is given that uses only one variable for each link (edge or arc) of the graph. Some properties of the…

A Novel Energy Model for MANETs based on Graphs with Activation Windows

2005

Energy usage optimization is still an important issue and a critical design factor for mobile ad hoc networks (MANETs). Only recently a few proposals appeared that consider energy-aware optimizations for routing protocols. In this paper we describe an analytical model for MANETs which is based on graphs with activation windows. The activation windows allow to model the on-off status of the network devices. Moreover, we propose an algorithm with pseudo-polynomial complexity, called STP algorithm (STPA), that based on the current position and state of the nodes determines the shortest time path between the source node and the destination node.

A Branch-and-Cut method for the Capacitated Location-Routing Problem

2011

International audience; Recent researches in the design of logistic networks have shown that the overall distribution cost may be excessive if routing decisions are ignored when locating depots. The Location-Routing Problem (LRP) overcomes this drawback by simultaneously tackling location and routing decisions. The aim of this paper is to propose an exact approach based on a Branch-and-Cut algorithm for solving the LRP with capacity constraints on depots and vehicles. The proposed method is based on a zero-one linear model strengthened by new families of valid inequalities. The computational evaluation on three sets of instances (34 instances in total), with 5–10 potential depots and 20–88 …

TBRA: A scalable routing algorithm in highly mobile large scale pure ad hoc wireless mesh networks

2009

In highly mobile pure ad-hoc wireless mesh networks, fast rerouting within low routing discovery delay is a mandatory requirement for routing algorithm to support interactive applications such as VoIP. Also, the communication overhead should be thwarted when networks grow to a large scale. We propose a Tree-Based Routing Algorithm - TBRA to facilitate such two goals. On one hand, TBRA has very low routing discovery delay due to its proactive property. On the other hand, TBRA performs more efficiently than other proactive protocols with respect to low communication overhead, which thanks to its short routing packet length, less numbers and smaller routing table size. Our modeling analysis an…

Logic-Based Distributed Routing for NoCs

2008

The design of scalable and reliable interconnection networks for multicore chips (NoCs) introduces new design constraints like power consumption, area, and ultra low latencies. Although 2D meshes are usually proposed for NoCs, heterogeneous cores, manufacturing defects, hard failures, and chip virtualization may lead to irregular topologies. In this context, efficient routing becomes a challenge. Although switches can be easily configured to support most routing algorithms and topologies by using routing tables, this solution does not scale in terms of latency and area. We propose a new circuit that removes the need for using routing tables. The new mechanism, referred to as logic-based dis…

Evaluating the Regional Impact of a New Road on Tourism

2004

Ferri J. (2004) Evaluating the regional impact of a new road on tourism, Reg. Studies 38, 409–418. The aim of this work is to establish whether the opening of a motorway that extends along the east coast of Spain has significantly contributed to expanding hotel tourism in the Valencia region. Some of the most important tourist destinations in Spain, both domestic and international, are located in this region, such as Benidorm, Peniscola and Gandia. The A-7 motorway, also part of the E-15 road network, is not only a faster and safer means of road communication for tourists but also provides a new gate to Europe, connecting with other motorways. Using monthly data on nights spent in hotels by…

Assessment of Tourist Competitiveness by Analysing Destination Efficiency

2006

Recently the notion and the measurement of destination competitiveness have received increasing attention in the economics literature on tourism. The reason for this interest emerges from both the increasing economic importance of the tourist sector and the increasing competition on the tourist market as a consequence of the transition from mass tourism to a new age of tourism that calls for a tailor-made approach to the specific attitudes and needs of tourists. The central subject of this paper - inspired by the conceptual competitiveness model developed earlier by Crouch and Ritchie - concerns the efficiency of tourist site destinations. Using a dataset of 103 Italian regions for the year…
