Abstract
The search for a sustainable development (in our case sustainable tourism) inescapably comes across with the concept of (tourism) carrying capacity, i.e. with the idea of the existence and possible identification, for both macro and micro destinations, of a maximum number of visitors beyond which the costs of tourism growth more than offset its benefits.

Abstract
One of the major changes recently noted in the evolution of world tourism demand seems to be represented by the shift from “sun and beach” holidays to more active and special interest ones. This trend will affect some destinations more than others. There will be losers and winners.

Abstract
Southern Italy (2) is a multiform and atypical system in the Italian tourist economy. According to a general image, one of its main features is the extensiveness and quality of the region's natural resources, especially the coastal areas, attractions which traditionally make the macroregion known essentially as a destination for “sun&sea” holidays. In recent years, moreover, due to growing and widespread awareness for environmental quality and for cultural factors, this image seems to have acquired new impulse and new occasions of interest. The wealth of particularly important historical, artistic and archaeological attractions (Magna Graecia, Roman and Arab‐Byzantine influences, the Baroque, etc); the diffusion and, often, the persistence of social‐cultural traditions that resist the influence of modernisation, are today—just as they were at the time of the Grand Tour—factors of strong appeal for the Southern regions. Today, the “capital cities” in Southern Italy are the main historical destinations of the early years of tourism, especially for foreign demand: besides Naples and Palermo, cities such as Taormina, Sorrento, Capri and Ischia, or destinations of cultural tourism such as Agrigento and Siracusa stand out.

Abstract
The purpose of this article is to describe the characteristics and the consumption behaviour of tourists coming from different countries and choosing different holiday typologies (cultural, seaside, mountains, etc.), by evaluating their expenditure in terms of consumption functions and productive sectors. The analysis — which uses the results of the survey on tourist expenditure carried out in the Veneto region, with particular reference to international tourism, from May 1994 to April 1995 —, can be suitably extended over the local scale. A multisectoral‐biregional input output model (VERDITOUR) has been implemented to measure the economic role of each segment and the plot of interactions going from tourist expenditure habits to the tourism industry.

Abstract
The TRIP (TouRism International Panel) Forecasting Models (1), the first regarding international tourist departures from each country of origin, the second international tourist flows to Italy and the third international departures from Italy, represent, through an appropriate mathematical and econometric analysis, the fixed effect approach of the panel data analysis, the economic process behind the foreign tourist's decision to holiday in Italy and the Italian tourist's decision to holiday abroad.

Abstract
The decoupling and asynchrony properties of the content‐based publish‐subscribe paradigm makes it very appealing for dynamic wireless networks, like those that often occur in pervasive computing scenarios. Unfortunately, most of the currently available content‐based publish‐subscribe middleware do not fit the requirements of such extreme scenarios, in which the network is subject to very frequent topological reconfigurations due to mobility of nodes. In this paper we propose a protocol for content‐based message dissemination tailored to Mobile Ad Hoc Networks (MANETs) showing frequent topological changes. Message routing occurs without the support of any network‐wide dispatching infrastructure thus eliminating the need of maintaining such infrastructure on top of a physical network continuously changing its topology. The paper reports an extensive simulation study that confirms the suitability of the proposed approach along with a stochastic analysis of the central mechanism adopted by the protocol.

Abstract
The evolution of the tourist industry has also led to a change in the provision of hospitality, which was previously concentrated on reception activities, but now includes a series of complementary activities which can be defined as “post‐reception” or, in some cases “post‐tourism” activities.

Abstract
Purpose
A novel method for modelling permanent magnets is investigated based on numerical approximations with rational functions. This study aims to introduce the AAA algorithm and other recently developed, cutting-edge mathematical tools, which provide outstandingly fast and accurate numerical computation of potentials and vector fields.
Design/methodology/approach
First, the AAA algorithm is briefly introduced along with its main variants and other advanced mathematical tools involved in the modelling. Then, the analysis of a circular Halbach array with a one-pole pair is carried out by means of the AAA-least squares method, focusing on vector potential and flux density in the bore and validating results by means of classic finite element software. Finally, the investigation is completed by a finite difference analysis.
Findings
AAA methods for field analysis prove to be strikingly fast and accurate. Results are in excellent agreement with those provided by the finite element model, and the very good agreement with those from finite differences suggests future improvements. They are also easy programming; the MATLAB code is less than 200 lines. This indicates they can provide an effective tool for rapid analysis.
Research limitations/implications
AAA methods in magnetostatics are novel, but their extension to analogous physical problems seems straightforward. Being a meshless method, it is unlikely that local non-linearities can be considered. An aspect of particular interest, left for future research, is the capability of handling inhomogeneous domains, i.e. solving general interface problems.
Originality/value
The authors use cutting-edge mathematical tools for the modelling of complex physical objects in magnetostatics.

Abstract
Purpose
Coproduction is both a recurrent way of organizing public services and a maturing academic field. The academic debate has analyzed several facets, but one deserves further analysis: its impact on the cost efficiency of public services. The purpose of this paper is to aim at systematizing the findings on the relationship between coproduction and cost efficiency and at developing insights for future research.
Design/methodology/approach
This paper is based on a structured literature review (SLR), following the approach proposed by Massaro, Dumay and Guthrie. The SLR approach differs from traditional narrative reviews since, like other meta-analysis methods, it adopts a replicable and transparent process. At the same time, when compared to most common meta-analysis or systematic review logics, it is better suited to incorporate evidence from case studies and etnographies. This makes the method especially suited to public administration and management studies.
Findings
Results shed light on the nature of the academic literature relating coproduction to cost efficiency, on what type of costs are affected and how and on the meaningfulness of productivity measures when public services are co-produced.
Originality/value
In times of fiscal distress for many governments, the paper contributes to research and practice in systematically re-assessing the effects of coproduction on public budgets.
