High-Order Parametrization of the Hypergeometric-Meijer Approximants
Creators: name: Shalaby, Abouzeid M.
Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In previous articles, we showed that, based on large-order asymptotic behavior, one can approximate a divergent series via the parametrization of a specific hypergeometric approximant. The analytical continuation is then carried out through a Mellin-Barnes integral representation of the hypergeometric approximant or equivalently using an equivalent form of the Meijer G-Function. The parametrization process involves the solution of a non-linear set of coupled equations which is hard to achieve (might be impossible) for high orders using normal PCs. In this work, we extend the approximation algorithm to accommodate any order (high or low) of the given series in a short time. The extension also allows us to employ non-perturbative information like strong-coupling and large-order asymptotic data which are always used to accelerate the convergence. We applied the algorithm for different orders (up to O($29$)) of the ground state energy of the $x^4$ anharmonic oscillator with and without the non-perturbative information. We also considered the available $20$ orders for the ground sate energy of the $\mathcal{PT}-$symmetric $ix^{3}$ anharmonic oscillator as well as the given $20$ orders of its strong-coupling expansion or equivalently the Yang-Lee model. For high order weak-coupling parametrization, accurate results have been obtained for the ground state energy and the non-perturbative parameters describing strong-coupling and large-order asymptotic behaviors. The employment of the non-perturbative data accelerated the convergence very clearly. The High temperature expansion for the susceptibility within the $SQ$ lattice has been also considered and led to accurate prediction for the critical exponent and critical temperature.
description: This is a self-contained version of the Hypergeometric-Meijer approximation algorithm we introduced before. In this version, one can parameterize high orders in short time and can accommodate non-perturbative parameters as well
Coordinated marketing and dissemination of knowledge: Jewish heritage tourism in Serra da Estrela, Portugal
Creators: name: Krakover, Shaul
Publisher: name: Journal of Tourism & Development
Year: 2012

description: It is logical to assume that coordinated marketing among all partners involved facilitates dissemination of knowledge regarding the marketed object. This study sets out to prove to what extent this assumption operates in marketing places for tourism. Specifically, the study explores the coordination between a regional agency and local municipalities in their efforts to introduce a new tourism product that of Jewish heritage tourism in the peripheral towns of Serra da Estrela, Portugal. The study utilizes internet site content analysis as its source of data. The data provide evidence that coordinated marketing is rewarded by synergic dissemination of knowledge regarding the new tourism product offered in those locations cooperating with the regional agency, and vice versa.

description: In this paper, we consider the time evolution of charge imbalance resolved negativity after a global quench in the 1+1 dimensional complex Klein-Gordon theory. We focus on two types of global quenches which are called boundary state quench and mass quench respectively. We first study the boundary state quench where the post-quench dynamic is governed by a massless Hamiltonian. In this case, the temporal evolution of charged imbalance resolved negativity can be obtained first by evaluating the correlators of the fluxed twist field in the upper half plane and then applying Fourier transformation. We numerical test our analytical formulas in the underlying lattice model. We also study the mass quench in the complex harmonic chain where the system is evolved according to a massive Hamiltonian after the quench. We argue that our results can be understood in the framework of quasi-particle picture.

description: A actividade turística não pára de se reinventar incorporando novas formas e fórmulas que satisfazem um turista cada vez mais exigente e experiente. O Geoturismo aparece como uma dessas soluções e compreende a exploração dos “Georrecursos Culturais” nas suas diversas formas naturais ou urbanas: como é o caso do “Circuito Turístico da Região dos Três Castelos” de Sebastião da Gama, na zona da Arrábida ou da “Geologia Eclesiástica” aplicada no Convento dos Cardaes, em Lisboa. Constitui-se como uma nova interpelação do espaço, do tempo e do entendimento de quem faz turismo, apresenta-se à realidade turística como um novo desafio que é preciso abraçar tendo em vista a competitividade turística que urge em território nacional. Este é ainda um bom exemplo da transdisciplinaridade e da mais valia científica e prática do cruzamento do Turismo com uma área científica que aqui se descobre complementar: a Geologia.

Using concatenated quantum codes for universal fault-tolerant quantum gates
Creators: name: Jochym-O'Connor, Tomas

Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)

description: We propose a method for universal fault-tolerant quantum computation using concatenated quantum error correcting codes. Namely, other than computational basis state preparation as required by the DiVincenzo criteria [1], our scheme requires no special ancillary state preparation to achieve universality, as opposed to schemes such as magic state distillation. The concatenation scheme exploits the transversal properties of two different codes, combining them to provide a means to protect against low-weight arbitrary errors. We give the required properties of the error correcting codes to ensure universal fault-tolerance and discuss a particular example using the 7-qubit Steane and 15-qubit Reed-Muller codes. We believe that optimizing the codes used in such a scheme could provide a useful alternative to state distillation schemes that exhibit high overhead costs.

Year: 2008

description: The positioning of a place constitutes a crucial cornerstone in destination management as the conveyed image is clearly an important influencer in buyers’ decision making. This paper focuses on how image is developed and managed in medium-sized urban areas. Two cases illustrate how local tourist boards define the key vectors underpinning the promotion and position of their regions as attractive destinations. This article discusses and comments upon the underlying strategies and their implementation in such urban centers. Managerial implications and avenues for future research are presented.

description: A graph is {\em locally irregular} if no two adjacent vertices have the same degree. A {\em locally irregular edge-coloring} of a graph $G$ is such an (improper) edge-coloring that the edges of any fixed color induce a locally irregular graph. Among the graphs admitting a locally irregular edge-coloring, i.e., {\em decomposable graphs}, only one is known to require $4$ colors, while for all the others it is believed that $3$ colors suffice. In this paper, we prove that decomposable claw-free graphs with maximum degree $3$, all cycle permutation graphs, and all generalized Petersen graphs admit a locally irregular edge-coloring with at most $3$ colors. We also discuss when $2$ colors suffice for a locally irregular edge-coloring of cubic graphs and present an infinite family of cubic graphs of girth $4$ which require $3$ colors.

Pilgrimage or sacred tourism? A modern phenomenon with historical roots, with examples from Fatima and Santiago de Compostela
Creators: name: Blom, Thomas

Publisher: name: Journal of Tourism & Development
Year: 2008

description: The aim of the article is both to discuss the phenomenon of pilgrim tourism from a post-modern perspective characterised by an increasing secularisation and to illustrate with the aid of a couple of examples - Santiago de Compostela in Spain and Fatima in Portugal – the distinctive features of this type of tourism-related product and link it to a regional development perspective. It isincreasingly obviousthat the world is becomingmore polarised with an orthodoxconservative religious wind blowing across the world at the same time as an increasingly secular view of life is gaining ground reducing religiousness in everyday life to a more subordinate position.We will therefore stress the importance of the desire to visit religious sites to find fellowship and achieve mental satisfaction is growing in importance. Irrespective of the individual’s purpose in making their journey to various sacred sites in the world, the tourist industry is growing in importance here and thus, in the future, ever greater demands will placed on the regional and local actors who receive visitors at these sites. There are considerable opportunities for these actors to further develop sacred tourism as a post-modern tourism niche.

description: We study the $M_{\rm HI}-M_{\star}$ relation over the last billion years using the MIGHTEE-HI sample. We first model the upper envelope of the $M_{\rm HI}-M_{\star}$ relation with a Bayesian technique applied to a total number of 249 HI-selected galaxies, without binning the datasets, while taking account of the intrinsic scatter. We fit the envelope with both linear and non-linear models, and find that the non-linear model is preferred over the linear one with a measured transition stellar mass of $\log_{10}(M_\star$/$M_{\odot})$ = $9.15\pm0.87$, beyond which the slope flattens. This finding supports the view that the lack of HI gas is ultimately responsible for the decreasing star formation rate observed in the massive main-sequence galaxies. For spirals alone, which are biased towards the massive galaxies in our sample, the slope beyond the transition mass is shallower than for the full sample, indicative of distinct gas processes ongoing for the spirals/high-mass galaxies from other types with lower stellar masses. We then create mock catalogues for the MIGHTEE-HI detections and non-detections with two main galaxy populations of late- and early-type galaxies to measure the underlying $M_{\rm HI}-M_{\star}$ relation. We find that the turnover in this relation persists whether considering the two galaxy populations as a whole or separately. We note that an underlying linear relation could mimic this turnover in the observed scaling relation, but a model with a turnover is strongly preferred. Measurements on the logarithmic average of HI masses against the stellar mass are provided as a benchmark for future studies.

O turismo religioso no norte de Portugal: avaliação do seu potencial de desenvolvimento

Year: 2008

description: Na última década a actividade turística aumentou o seu impacte em Portugal, tanto social como economicamente, tendo-se registado mais de 11 milhões de entradas de turistas e quase 23 milhões de entradas de visitantes em 2006. No entanto, subsistem enormes diferenças quanto à distribuição de tais fluxos, mormente entre a faixa litoral e a interior observando-se, também, uma concentração crescente em torno de três áreas de destino, Algarve, Madeira e Costa de Lisboa. Tal situação justifica a necessidade de se diversificar o produto turístico nacional a fim de se diminuir a importância das suas componentes ditas tradicionais. Uma das componentes com potencial para contribuir para essa diversificação é o turismo cultural, através do aproveitamento e maximização das suas várias vertentes, quer construtivas, quer imateriais, disseminadas de Norte a Sul do país. Para alcançar tal desígnio importa realçar que parte muito significativa desse património cultural português é propriedade da Igreja Católica (Falcão, 2002), o que indicia que um dos produtos potencialmente com maior expressão é o “turismo religioso”. Este artigo descreve a metodologia usada para a execução do estudo Turismo Religioso – Promoção e Dinamização do Turismo Religioso como Motor de Desenvolvimento Regional. O objectivo principal da pesquisa foi o de estabelecer o potencial de diferentes áreas do Norte de Portugal para o turismo religioso, e sobretudo as oportunidades para o desenvolvimento à volta dos chamados “locais-âncora” na região.

description: We consider torsion in parameter manifolds that arises via conformal transformations of the Fisher information metric, and define it for information geometry of a wide class of physical systems. The torsion can be used to differentiate between probability distribution functions that otherwise have the same scalar curvature and hence define similar geometries. In the context of thermodynamic geometry, our construction gives rise to a new scalar - the torsion scalar defined on the manifold, while retaining known physical features related to other scalar quantities. We analyse this in the context of the Van der Waals and the Curie-Weiss models. In both cases, the torsion scalar has non trivial behaviour on the spinodal curve.

description: Accurate detection and classification of vulnerable road users is a safety critical requirement for the deployment of autonomous vehicles in heterogeneous traffic. Although similar in physical appearance to pedestrians, e-scooter riders follow distinctly different characteristics of movement and can reach speeds of up to 45kmph. The challenge of detecting e-scooter riders is exacerbated in urban environments where the frequency of partial occlusion is increased as riders navigate between vehicles, traffic infrastructure and other road users. This can lead to the non-detection or mis-classification of e-scooter riders as pedestrians, providing inaccurate information for accident mitigation and path planning in autonomous vehicle applications. This research introduces a novel benchmark for partially occluded e-scooter rider detection to facilitate the objective characterization of detection models. A novel, occlusion-aware method of e-scooter rider detection is presented that achieves a 15.93% improvement in detection performance over the current state of the art.
The dark energy as a natural property of cosmic polytropes -- A tutorial

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Theoretical results on a conventional approach to the dark energy (DE) concept are reviewed and discussed. According to them, there is absolutely no need for a novel DE component in the Universe, provided that the associated matter-energy content is represented by a perfect fluid whose volume elements perform polytropic flows. When the thermodynamic energy of this fluid's internal motions is also considered as a source of the universal gravitational field, it compensates the DE needed to compromise spatial flatness in an accelerating Universe. The cosmological model with matter-energy content in the form of a polytropic fluid not only interprets the observations associated to the recent history of Universe expansion, but successfully confronts with all the current cosmological issues, thus arising as a viable alternative to $\Lm$CDM model.

description: The LIGO-Virgo gravitational wave detectors have confidently observed 4 events involving neutron stars: two binary neutron star (BNS) mergers (GW170817 and GW190425), and two neutron star-black hole mergers (GW200105 and GW200115). However, our theoretical understanding of the remnant properties of such systems is incomplete due to the complexities related to the modeling of matter effects and the very high computational cost of corresponding numerical relativity simulations. An important such property is the recoil velocity, which is imparted onto the remnant due to the anisotropic emission of gravitational radiation and the dynamical ejection of matter in the kilonova. In this work, we combine gravitational radiation as well as dynamical ejecta distributions, computed by the Computational Relativity numerical simulations, to get accurate estimates for BNS remnant recoil velocities. We find that recoils due to ejection of matter dominate those caused by gravitational wave emission. Knowledge of BNS remnant recoil velocities is important in determining if the remnant is retained by its environment for future hierarchical mergers which, in turn, can form binaries with black holes in the so-called lower mass gap of 3 to 5 solar masses.

description: We review the status of axino dark matter. Two hierarchy problems, the strong CP problem and the gauge hierarchy problem, have led to introducing into particle physics a spontaneously broken global Peccei-Quinn symmetry and a softly broken supersymmetry, respectively. Combining them implies the presence of not only an axion, but also of its scalar component, saxion, and their fermionic partner, axino. Among these, the axion and the axino are attractive dark matter candidates. Various possibilities for the axino as dark matter are discussed.

description: O ser humano só consome aquilo para que está motivado. A motivação envolve um processo de escolha, baseado nos atributos do produto percebidos pelo consumidor. As motivações que determinam as preferências dos golfistas constituem uma incógnita para a maior parte dos empresários. Este trabalho pretende avaliar os factores de escolha dos campos de golfe, num espaço assumido como o primeiro destino de golfe, ao nível da Europa, Almancil. Sustentado numa recolha de dados primários, resultantes dum inquérito aos golfistas, segmenta-se o mercado de golfe em Almancil, numa perspectiva psicográfica, utilizando, como ferramentas, a Análise de Componentes Principais e a Análise de Clusters. Prova-se que o golfista utiliza um reduzido número de atributos para formar a percepção dos campos de golfe, entre os quais se destaca o factor holístico, o factor destino e o factor golfe. As dimensões de escolha foram utilizadas como variáveis de segmentação. A análise de clusters permitiu identificar três segmentos, designados por “Turista que joga golfe”, o “Jogador de grupo” e o “Golfista jogador”, que constituem a procura de turismo de golfe, em Almancil.

description: Count data occur widely in many bio-surveillance and healthcare applications, e.g., the numbers of new patients of different types of infectious diseases from different cities/counties/states repeatedly over time, say, daily/weekly/monthly. For this type of count data, one important task is the quick detection and localization of hot-spots in terms of unusual infectious rates so that we can respond appropriately. In this paper, we develop a method called Poisson assisted Smooth Sparse Tensor Decomposition (PoSSTenD), which not only detects when hot-spots occur but also localizes where hot-spots occur. The main idea of our proposed PoSSTenD method is articulated as follows. First, we represent the observed count data as a three-dimensional tensor including (1) a spatial dimension for location patterns, e.g., different cities/countries/states; (2) a temporal domain for time patterns, e.g., daily/weekly/monthly; (3) a categorical dimension for different types of data sources, e.g., different types of diseases. Second, we fit this tensor into a Poisson regression model, and then we further decompose the infectious rate into two components: smooth global trend and local hot-spots. Third, we detect when hot-spots occur by building a cumulative sum (CUSUM) control chart and localize where hot-spots occur by their LASSO-type sparse estimation. The usefulness of our proposed methodology is validated through numerical simulation studies and a real-world dataset, which records the annual number of 10 different infectious diseases from 1993 to 2018 for 49 mainland states in the United States.

Assim, focalizando-nos na abrangência e articulação de conceitos como lazer, turismo e termalismo, torna-se imperioso não só proceder à sua clarificação, como também associá-los a novos paradigmas da sociedade actual, reflectindo sobre terminologias emergentes e áreas de abrangência e conexão inerentes aos mesmos. Cientes de que tanto o lazer como o turismo se classificam como actividades desenvolvidas em contexto de tempo(s) livre(s), associando-se a necessidades de relaxamento, prazer e bem-estar, que abrangência conceptual se poderá atribuir hoje ao termalismo? Constituindo-se como uma das formas de turismo mais remota, que áreas ou franjas do termalismo penetram, na actualidade, na actividade turística? E que adaptações se têm exigido a tais ofertas de forma a consolidar a sua importância em projectos turísticos estruturantes?

description: The teaching of tourism at a higher education level has become well established in Portuguese Higher Education (HE) institutions.The academic curriculum needs to change in Tourism courses in order to implement the Bologna Process in Portugal. We have taken into consideration the diversity of tourism courses and approaches, from the agents’ viewpoints that are influencing the new design of academic curricula in Portugal. We concluded that tourism education needs a common and negotiated approach as an area of study that is difficult to categorize and this is reflected in the development of new curriculum perspectives. This research paper essentially reflects an empirical application to the Portuguese situation.

The delphi technique applied to urban and cultural tourism research in the Algarve
Creators: name: Gonçalves, Alexandra Rodrigues
Publisher: name: Journal of Tourism & Development
Year: 2007

description: Urban tourism is a major economic and social activity where the cultural dimension of cities is one of the main factors that attract visitors. The present work results from a dissertation thesis that aimed to evaluate the existence of cultural tourism in the towns of Faro and Silves and proposed means of fostering such activities in the future. The “transversality” of knowledge linked to tourism and the dynamics it can create make tourism one of the most difficult activities to quantify and evaluate. The developed investigation can be translated into an integrating approach of the concept of cultural patrimony and urban tourism, domains that so far have stayed apart. The use of several investigative methods in a complementary way – group interviews, Delphi method and case study (three sided methods) –, have revealed to be a strong point in the applied methodology. On the other hand, as will be shown later, the Delphi technique, although revealing some difficulties of application, and not being a decisive instrument nor being often used in tourism, has been very useful for the treatment of qualitative information. So we will introduce the main methodologies used on our research and analyse the various methods available for tourism research. Some of the acquired results are also summarized and specified in the case studies, highlighting the potential that the combination of several investigative methods have brought in helping to discover the answer to proposed aims.

Analytic expressions for spin-wave properties show that the interfacial Dzyaloshinskii-Moriya interaction leads to non-reciprocal spin-wave propagation, i.e. different properties for spin waves propagating in opposite directions. In favorable situations, it can increase the spin-wave attenuation length. Comparing measured spin wave properties in ferromagnet$|$normal metal bilayers and other artificial layered structures with these calculations can provide a useful characterization of the interfacial Dzyaloshinskii-Moriya interactions.

description: Zero-shot learning (ZSL) aims to identify unseen classes with zero samples during training. Broadly speaking, present ZSL methods usually adopt class-level semantic labels and compare them with instance-level semantic predictions to infer unseen classes. However, we find that such existing models mostly produce imbalanced semantic predictions, i.e. these models could perform precisely for some semantics, but may not for others. To address the drawback, we aim to introduce an imbalanced learning framework into ZSL. However, we find that imbalanced ZSL has two unique challenges: (1) Its imbalanced predictions are highly correlated with the value of semantic labels rather than the number of samples as typically considered in the traditional imbalanced learning; (2) Different semantics follow quite different error distributions between classes. To mitigate these issues, we first formalize ZSL as an imbalanced regression problem which offers empirical evidences to interpret how semantic labels lead to imbalanced semantic predictions. We then propose a re-weighted loss termed Re-balanced Mean-Squared Error (ReMSE), which tracks the mean and variance of error distributions, thus ensuring rebalanced learning across classes. As a major contribution, we conduct a series of analyses showing that ReMSE is theoretically well established. Extensive experiments demonstrate that the proposed method effectively alleviates the imbalance in semantic prediction and outperforms many state-of-the-art ZSL methods.

Nature of the 1/9-magnetization plateau in the spin-1/2 kagome Heisenberg antiferromagnet

description: The nature of the 1/9-magnetization plateau of the spin-1/2 kagome Heisenberg antiferromagnet remains controversial due to the exotic physical properties and high complexity induced by the geometrical frustration. Instead of a Z3 quantum spin liquid revealed on a cylinder, we show on an infinite-size lattice that the 1/9 plateau can be described by a valence bond crystal (VBC) that breaks spatial translational invariance. Consistent results are achieved by two accurate tensor network methods, namely the full-update infinite projected-entangled pair states and the projected-entangled simplex states. The VBC exhibits an hourglass pattern with $\sqrt{3}\times\sqrt{3}$ spatial symmetry, demonstrated by magnetizations, bond energies, and three-body correlators. The spatial inversion symmetry in the $\sqrt{3}\times\sqrt{3}$ VBC is instantly broken with the presence of the difference between the coupling strengths in the up and down triangles, suggesting the existence of gapless excitations. The gapless nature of the 1/9 plateau is further indicated by the scaling behaviors of the entanglement entropy and the correlation length, which indicate a c=1 conformal field theory.

Investment valuation: exploring the intrinsic value of resort industry in Taiwan by discounted cash flow models
Creators: name: Liu, Yi-De
Publisher: name: Journal of Tourism & Development
Year: 2007

description: In Taiwan, leisure industry is currently one of the core industries and plays an important role in economic contribution to the country. However,most investors are unfamiliar with this industry and itsvalue,causing uncertainties in financing and its sustainable development. The aim of this research is to estimate the intrinsic value of selected company – Kentington Resort by three discounted cash flow models, i.e. dividend discount model, free cash flow to equity model and free cash flow to firm model. The research findings show that two free cash flow models are more appropriate while valuing Kentington and current market prices reflect basically its intrinsic value. In order to examine the stability of the valuation methodology, a series of sensitivity analyses are also taken in the end. By referring to this investment valuation process, managers and investors could improve the quality of their decision making and investment.

Limiting velocities and transonic dislocations in Mg

description: To accurately predict the mechanical response of materials, especially at high strain rates, it is important to account for dislocation velocities in these regimes. Under these extreme conditions, it has been hypothesized that dislocations can move faster than the speed of sound. However, the presence of such dislocations remains elusive due to challenges associated with measuring these experimentally. In this work, molecular dynamics simulations were used to investigate the dislocation velocities for the basal edge, basal screw, prismatic edge, and prismatic screw dislocations in Mg in the sub-, trans-, and supersonic regimes. Our results show that only prismatic edge dislocations achieve supersonic velocities. Furthermore, this work demonstrates that the discrepancy between the theoretical limiting velocity and the MD results for Mg is due to its sensitivity to large hydrostatic stress around the dislocation core, which was not the case for fcc metals such as Cu.

description: We consider scaled Brownian motion (sBm), a random process described by a diffusion equation with explicitly time-dependent diffusion coefficient $D(t) = D_0 t^{α- 1}$ (Batchelor's equation) which, for $α< 1$, is often used for fitting experimental data for subdiffusion of unclear genesis. We show that this process is a close relative of subdiffusive continuous-time random walks and describes the motion of the center of mass of a cloud of independent walkers. It shares with subdiffusive CTRW its non-stationary and non-ergodic properties. The non-ergodicity of sBm does not however go hand in hand with strong difference between its different realizations: its heterogeneity ("ergodicity breaking") parameter tends to zero for long trajectories.

description: Inferring transient molecular structural dynamics from diffraction data is an ambiguous task that often requires different approximation methods. In this paper we present an attempt to tackle this problem using machine learning. While most recent applications of machine learning for the analysis of diffraction images apply only a single neural network to an experimental dataset and train it on the task of prediction, our approach utilizes an additional generator network trained on both synthetic data and experimental data. Our network converts experimental data into idealized diffraction patterns from which information is extracted via a convolutional neural network (CNN) trained on synthetic data only. We validate this approach on ultrafast electron diffraction (UED) data of bismuth samples undergoing thermalization upon excitation via 800 nm laser pulses. The network was able to predict transient temperatures with a deviation of less than 6% from analytically estimated values. Notably, this performance was achieved on a dataset of 408 images only. We believe employing this network in experimental settings where high volumes of visual data are collected, such as beam lines, could provide insights into the structural dynamics of different samples.
Modelling and forecasting tourism demand in Portugal: past, present and future

description: A literature survey shows that considerable attention has been given to tourism demand forecasting. However, in Portugal only the Direcção Geral do Turismo (General Tourism Board), Investimentos, Comércio e Turismo de Portugal (Investments, Commerce and Tourism for Portugal), and academic researchers have carried out some work on tourism demand modelling and forecasting. Research on recent developments and methodologies for modelling and forecasting tourism in Portugal is still quite limited. Hence, the main purpose of this paper is to surveythe empirical research available to date for Portugal and provide suggestions for future studies.

Year: 2007

description: This paper sees the Internet as an important source of information for independent travellers, but that it is predominantly used in conjunction with more traditional information sources. It also concludes that the Internet cannot be considered as a single resource, as the Internet has the ability to transcend the divides between commerciality and personalisation. In order to establish this importance, and the contribution that the Internet has made to the way in which independent travellers select their destinations, a quantitative survey of independent travellers was conducted. This survey investigated the relationships between the Internet and destination choice by testing a series of hypotheses. This study explores the importance of this technology to the independent traveller, and how use of the Internet as a tool for the distribution of information on a destination can have a bearing on the independent travellers’ decision-making and planning processes.
