description: For many European destinations the binomial ‘typical product-tourism’ is becoming a trigger tool for rural development. This work focuses on highlighting the tourist potential of the olive oil. This product boasts a strong cultural identity that can be exploited for tourism diversification of the olive grove rural areas. The objective of this work is to put forward a proposal for the development of these areas from an integral, sustainable and participative perspective. A tourism management model that can be applied to the olive groves areas of southern Europe is proposed. The foreseeable results would allow the improvement of local economy, agricultural sector and tourism, as well as other indirect benefits associated with the enhancement of the quality of life of the local community.

Tourism demand and tourism growth cycles in Portugal and Spain
Creators: name: Bento, João Paulo Cerdeira

Publisher: name: Journal of Tourism & Development
Year: 2014

description: This paper investigates the patterns of tourism growth cycles in domestic and international tourism demand for Portugal and Spain with monthly data on visitor’s arrivals in tourist accommodation establishments from January 1990 to September 2013. The de-trending method proposed by Hodrick-Prescott filter is used to extract the tourism growth cycles for both resident and non-resident tourists. The Bry-Boschan algorithm finds that the duration of contractions tend to be on average twice longer for resident tourists than for non-resident tourists, and the length of expansions is almost three times higher for non-resident tourists than for resident ones in Portugal. The duration of the tourism growth cycles is much higher in Portugal than in Spain in both groups of tourists by ten to twelve months. Large expansion phases in Portugal tend to coexist with large contraction phases in Spain along the cycles from non-resident tourists. Spectral analysis confirms the existence of one dominant cyclic frequency within tourism demand from both tourist groups. The paper is concluded with a brief discussion of findings.

description: The Sloan Digital Sky Survey (SDSS) provides data on several hundred thousand galaxies. Precise location of these galaxies in the sky, along with information about their luminosities and line-of-sight (Doppler) velocities allows one to construct a three-dimensional map of their location and estimate their line-of-sight velocity dispersion. This information, in principle, allows one to test dynamical gravity models, specifically models of satellite galaxy velocity dispersions near massive hosts. A key difficulty is the separation of true satellites from interlopers. We sidestep this problem by not attempting to derive satellite galaxy velocity dispersions from the data, but instead incorporate an interloper background into the mathematical models and compare the result to the actual data. We find that due to the presence of interlopers, it is not possible to exclude several gravitational theories on the basis of the SDSS data.

description: Tumors involving bone and soft tissues are extremely challenging situations. With the recent advances of multi-modal treatment, not only the type of surgery has moved from amputation to limb-sparing procedures, but also the survivorship has improved considerably and reconstructive techniques have the goal to allow a considerably higher quality of life. In bone reconstruction, tissue engineering strategies are the main area of research. Re-vascularization and re-vitalisation of a massive allograft would considerably improve the outcome of biological reconstructions. Using a rabbit animal model, in this study we showed that, by implanting a vascular pedicle inside a weight bearing massive cortical allograft, the bone regeneration inside the allograft was higher compared to the non-vascularized implants, given the patency of the vascular pedicle. Improvement in the animal model and the addition of Stem Cells and Growth factors will allow a further improvement in the results. In soft tissue tumors, free and pedicled flaps have been proven to be of great help as reconstruction strategies. In this study we analyzed the functional and overall outcome of 14 patients who received a re-innervated vascularized flap. We have demonstrated that the use of the innovative technique of motor re-innervated muscular flaps is effective when the resection involves important functional compartments of the upper or lower limb, with no increase of post-operative complications. Although there was no direct comparison between this type of reconstruction and the standard non-innervated reconstruction, we underlined the remarkable high overall functional scores and patient satisfaction following this procedure.
Contrasting Pair-Breaking Effects by Doping Mn and Zn in Ba0.5K0.5Fe2As2

description: Resistivity, Hall effect, magnetoresistance and DC magnetization were measured in Mn and Zn doped Ba$_{0.5}$K$_{0.5}$Fe$_{2}$As$_{2}$ samples. It is found that the Mn-doping can depress the superconducting transition temperature drastically with a rate of $ΔT_c$/Mn-1% = -4.2 K, while that by Zn-doping is negligible. Detailed analysis reveals that the Mn-doping enhances the residual resistivity ($ρ_0$) significantly, and induces strong local magnetic moments ($\sim$ 2.58 $μ_B$) which play as pair breakers. While the impurity scattering measured by $ρ_0$ in the Zn-doped samples is much weaker, accompanied by a negligible pair breaking effect. A possible explanation is that the impurity scattering by the Zn impurities are mainly small angle scattering (or small momentum transfer), therefore it cannot break the pairing induced by the interpocket scattering and thus affect the superconducting transition temperature weakly.

description: O atual ambiente competitivo alterou a lógica da criação de valor, deixando de se centrar unicamente na ‘cadeia de valor’, interna à organização, para também absorver inputs da ‘constelação de valor’ externa à organização. Por isso, o novo paradigma de negócio das agências de viagens independentes (AVI) deve ser redefinido, procurando o reforço das relações win-win com os seus parceiros operadores turísticos (OT). O propósito deste artigo é identificar os atributos da constelação de valor destes parceiros de negócio e medir a importância do relacionamento quanto à criação de valor. Existe uma perceção das AVI, de que os OT investem mais em estratégias ligadas à eficiência dos seus processos internos e menos em relacionamentos com parceiros e em cocriação de valor. Assim, o objetivo desta investigação será construir um mosaico de ideias que possam explicar a realidade de criação de valor entre os parceiros das AVI, os OT e mobilizá-los no incremento de novas maneiras de cocriar valor, já que esta tendência norteará a próxima vaga de crescimento e de produtividade, na economia global.

description: Macrogases are defined as two-component, large-scale celestial objects where the subsystems interact only via gravitation. The macrogas equation of state is formulated and compared to the van der Waals equation of state for ordinary gases. By analogy, it is assumed that real macroisothermal curves in macrogases occur as real isothermal curves in ordinary gases, where a phase transition takes place along a horisontal line in the macrovolume-macropressure (Mv-Mp) plane. A simple guidance case and two density profiles which satisfactorily fit to observations or simulations, are studied in detail. For sufficiently steep density profiles, a critical macroisothermal curve exists as shown by ordinary gases, where the critical point coincides with the horisontal inflexion point. By analogy with ordinary gases, the first quadrant of the (Mv-Mp) plane may be divided into three parts, namely (i) the G region, where only gas exists; (ii) the S region, where only stars exist; (iii) the GS region, where both gas and stars exist. An application is made to a subsample of elliptical galaxies investigated within the SAURON project. Different models characterized by equal subsystem mass ratio and different scaled truncation radii, are considered and the related position of sample objects on the (Mv-Mp) plane is determined. Tipically, fast rotators are found to lie within the S region, while slow rotators are close (from both sides) to the boundary between the S and the GS region. The net effect of the uncertainty affecting observed quantities, on the position of sample objects on the (Mv-Mp) plane, is also investigated. Finally, a principle of corresponding states is formulated for macrogases with assigned density profiles and scaled truncation radii.

description: Nos últimos trinta anos, a indústria de timeshares tem vivenciado um desenvolvimento significante e sustentável, sendo atualmente o seguimento do turismo que mais cresce no mundo. Apesar da visível importância econômica do setor, a literatura acadêmica sobre o assunto ainda é incipiente. A fim de colaborar com o preenchimento dessa lacuna, o presente trabalho tem por objetivo analisar o sistema de tempo compartilhado sob a perspectiva da governança coorporativa, utilizando como base a teoria da agência. Através de uma revisão bibliográfica foram levantadas proposições a respeito de problemas de agência emergentes em sistemas de tempo compartilhado. Posteriormente tais proposições foram verificadas empiricamente com um estudo de caso sobre o timeshare do complexo turístico Beach Park. Por fim, pudemos concluir que as estruturas de governança típicas do modelo de negócio estudado são frágeis, prejudicando assim seu desenvolvimento no Brasil.

description: Dynamics of neutral modes for fractional quantum Hall states is investigated for a quantum point contact geometry in the weak-backscattering regime. The effective field theory introduced by Fradkin-Lopez for edge states in the Jain sequence is generalized to the case of propagating neutral modes. The dominant tunnelling processes are identified also in the presence of non-universal phenomena induced by interactions. The crossover regime in the backscattering current between tunnelling of single-quasiparticles and of agglomerates of p-quasiparticles is analysed. We demonstrate that higher order cumulants of the backscattering current fluctuations are a unique resource to study quantitatively the competition between different carrier charges. We find that propagating neutral modes are a necessary ingredient in order to explain this crossover phenomena.

Subjects: ING-IND/31 Elettrotecnica

description: Research work carried out in focusing a novel multiphase-multilevel ac motor drive system much suitable for low-voltage high-current power applications. In specific, six-phase asymmetrical induction motor with open-end stator winding configuration, fed from four standard two-level three-phase voltage source inverters (VSIs). Proposed synchronous reference frame control algorithm shares the total dc source power among the 4 VSIs in each switching cycle with three degree of freedom. Precisely, first degree of freedom concerns with the current sharing between two three-phase stator windings. Based on modified multilevel space vector pulse width modulation shares the voltage between each single VSIs of two three-phase stator windings with second and third degree of freedom, having proper multilevel output waveforms. 
Complete model of whole ac motor drive based on three-phase space vector decomposition approach was developed in PLECS - numerical simulation software working in MATLAB environment. Proposed synchronous reference control algorithm was framed in MATLAB with modified multilevel space vector pulse width modulator. The effectiveness of the entire ac motor drives system was tested. Simulation results are given in detail to show symmetrical and asymmetrical, power sharing conditions. Furthermore, the three degree of freedom are exploited to investigate fault tolerant capabilities in post-fault conditions. Complete set of simulation results are provided when one, two and three VSIs are faulty.
Hardware prototype model of quad-inverter was implemented with two passive three-phase open-winding loads using two TMS320F2812 DSP controllers. Developed McBSP (multi-channel buffered serial port) communication algorithm able to control the four VSIs for PWM communication and synchronization. Open-loop control scheme based on inverse three-phase decomposition approach was developed to control entire quad-inverter configuration and tested with balanced and unbalanced operating conditions with simplified PWM techniques. 
Both simulation and experimental results are always in good agreement with theoretical developments.

description: This thesis is mainly devoted to show how EEG data and related phenomena can be reproduced and analyzed using mathematical models of neural masses (NMM). The aim is to describe some of these phenomena, to show in which ways the design of the models architecture is influenced by such phenomena, point out the difficulties of tuning the dozens of parameters of the models in order to reproduce the activity recorded with EEG systems during different kinds of experiments, and suggest some strategies to cope with these problems. In particular the chapters are organized as follows: chapter I gives a brief overview of the aims and issues addressed in the thesis; in chapter II the main characteristics of the cortical column, of the EEG signal and of the neural mass models will be presented, in order to show the relationships that hold between these entities; chapter III describes a study in which a NMM from the literature has been used to assess brain connectivity changes in tetraplegic patients; in chapter IV a modified version of the NMM is presented, which has been developed to overcomes some of the previous version’s intrinsic limitations; chapter V describes a study in which the new NMM has been used to reproduce the electrical activity evoked in the cortex by the transcranial magnetic stimulation (TMS); chapter VI presents some preliminary results obtained in the simulation of the neural rhythms associated with memory recall; finally, some general conclusions are drawn in chapter VII.

description: Background. Intravenous steroids represent the mainstay of therapy for severe attacks of Ulcerative Colitis (UC). In steroid refractory patients, both iv cyclosporine (CsA) and infliximab (IFX) are valid rescue therapies. Several studies have shown that oral microemulsion CsA (Neoral) is equivalent to iv CsA in term of safety and efficacy in UC patients. 
Aim. To investigate the efficacy and safety of oral microemulsion CsA vs IFX in patients with severe attack of UC, refractory to iv steroids. 
Material and methods. From May 2006, all consecutive pts admitted for severe UC were considered eligible. Pts were treated with iv steroid, according to the Oxford regime. After 1 week of intensive treatment, pts non responder to the therapy and not candidate to the surgery, were asked to participate to the trial. They were randomised to receive IFX 5 mg/kg or oral CsA 5 mg/kg. 
Results. A total of 30 patients were randomised, 17 in the IFX group and 13 in the CsA group. One month after study inclusion, 9 patients of the IFX group (53%) and 7 pts of the CsA group (54%) were in clinical remission (p=0.96), with a Powell-Tuck index ≤ 3. At the end of the follow-up, 7 pts in the IFX group (41%) vs 4 in the CsA group (31%) (p=0.35) underwent colectomy. The total cost of the IFX therapy with IFX was 8.052,84 € versus 1.106,82 €, for each patient.
Conclusions. Oral microemulsion CsA and IFX seem to be equivalent in term of efficacy and safety in severe UC patients refractory to iv steroids. In patients treated with IFX the cost of therapy were significantly higher.

description: This thesis addresses the formulation of a referee assignment problem for the Italian Volleyball Serie A Championships. The problem has particular constraints such as a referee must be assigned to different teams in a given period of times, and the minimal/maximal level of workload for each referee is obtained by considering cost and profit in the objective function. The problem has been solved through an exact method by using an integer linear programming formulation and a clique based decomposition for improving the computing time. Extensive computational experiments on real-world instances have been performed to determine the effectiveness of the proposed approach.

description: From the perspective of a new-generation opto-electronic technology based on organic semiconductors, a major objective is to achieve a deep and detailed knowledge of the structure-property relationships, in order to optimize the electronic, optical, and charge transport properties by tuning the chemical-physical characteristics of the compounds. The purpose of this dissertation is to contribute to such understanding, through suitable theoretical and computational studies. Precisely, the structural, electronic, optical, and charge transport characteristics of several promising organic materials recently synthesized are investigated by means of an integrated approach encompassing quantum-chemical calculations, molecular dynamics and kinetic Monte Carlo simulations. Particular care is addressed to the rationalization of optical and charge transport properties in terms of both intra- and intermolecular features. Moreover, a considerable part of this project involves the development of a home-made set of procedures and parts of software code required to assist the modeling of charge transport properties in the framework of the non-adiabatic hopping mechanism applied to organic crystalline materials.
As a first part of my investigations, I mainly discuss the optical, electronic, and structural properties of several core-extended rylene derivatives, which can be regarded to as model compounds for graphene nanoribbons. Two families have been studied, consisting in bay-linked perylene bisimide oligomers and N-annulated rylenes. 
Beside rylene derivatives, my studies also concerned electronic and spectroscopic properties of tetracene diimides, quinoidal oligothiophenes, and oxygen doped picene.
As an example of device application, I studied the structural characteristics governing the efficiency of resistive molecular memories based on a derivative of benzoquinone.
Finally, as a second part of my investigations, I concentrate on the charge transport properties of perylene bisimides derivatives. Precisely, a comprehensive study of the structural and thermal effects on the charge transport of several core-twisted chlorinated and fluoro-alkylated perylene bisimide n-type semiconductors is presented.

description: Apesar de serem muitas as teorias que sugerem uma explicação para a realização do comércio internacional, tentando justificar porque é que determinados países são mais atrativos para Investimento Direto Estrangeiro (IDE) do que outros, os autores são unânimes ao afirmar que o IDE é influenciado por fatores de atração (características específicas dos países de acolhimento) e por fatores impulsionadores (características específicas das empresas e do país de origem das mesmas). Este estudo tem como objetivo identificar os principais fatores de atratividade para IDE no setor do turismo português. Com essa finalidade construiu-se um modelo teórico, que foi validado através de entrevistas exploratórias semiestruturadas e da aplicação de inquéritos por questionário aos investidores estrangeiros a explorar unidades de alojamento em Portugal. Os resultados obtidos permitem concluir que a localização geográfica de Portugal, a imagem/marca do setor do turismo português e a oferta turística portuguesa são considerados os fatores de atração mais importantes para IDE. Este estudo identificou, ainda, que os maiores entraves ao IDE são a burocracia, a carga fiscal e a atual situação económica do país.

description: The concern with the need for leaders in the nursing profession as well as knowledge that many current nursing leaders advocate alliance with the Women's Liberation Movement, gave rise to the study of leadership characteristics, attitudes towards feminism, and the relationship between these in selected female populations. The samples chosen for study were thirty graduating baccalaureate nursing students, thirty members of organized groups of the Women's Liberation Movement, and as another comparison group, twenty four library science students. Five hypotheses concerning leadership characteristics and attitudes towards feminism were tested. The hypotheses were: 1. There is no significant difference in leadership characteristics, as measured by scores on the Gordon Personal Profile and the Gordon Personal Inventory, among students graduating from a baccalaureate nursing program, women belonging to organized groups of the Women's Liberation Movement, and students in a library science program. 2. There is no significant difference in attitudes towards feminism, as measured by the FEM scale, among students graduating from a baccalaureate nursing program, women belonging to organized groups of the Women's Liberation Movement, and students in a library science program. 3. There is no significant relationship between attitudes towards feminism, as measured by the FEM scale, and leadership characteristics, as measured by scores on the Gordon Personal Profile and the Gordon Personal Inventory, in graduating baccalaureate nursing students. There is no significant relationship between attitudes towards feminism, as measured by the FEM scale, and leadership characteristics, as measured by scores on the Gordon Personal Profile and the Gordon Personal Inventory, in women belonging to organized groups of the Women's Liberation Movement. 5. There is no significant relationship between attitudes towards feminism, as measured by the FEM scale, and leadership characteristics, as measured by scores on the Gordon Personal Profile and the Gordon Personal Inventory, in students of a library science program. No significant differences in leadership characteristics among the three groups were found. Significant differences in attitudes towards feminism were found with the members of the Women's Liberation Movement differing most from the other two groups. No significant relationships between leadership characteristics and attitudes towards feminism were found in any of the three groups. It was concluded that a belief in feminism does not cause leadership characteristics, and that leadership characteristics do not cause a belief in feminism. Similarly, any other variable common to the three groups could not be considered causal for both the possession of leadership characteristics and the expressed attitudes towards feminism.

description: Inspired by the translational gauge structure of teleparallel gravity, the theory for a fundamental massless spin-2 field is constructed. Accordingly, instead of being represented by a symmetric second-rank tensor, the fundamental spin-2 field is assumed to be represented by a spacetime (world) vector field assuming values in the Lie algebra of the translation group. The flat-space theory naturally emerges in the Fierz formalism and is found to be equivalent to the usual metric-based theory. However, the gravitationally coupled theory, with gravitation itself described by teleparallel gravity, is shown not to present the consistency problems of the spin-2 theory constructed on the basis of general relativity.

description: A interpretação é apontada como um elemento chave para a prática de um turismo mais sustentável, apresentando-se como uma solução para muitos dos problemas e conflitos que advêm da atividade turística, conjugando os interesses do visitante, dos territórios, dos recursos e da comunidade local. Partindo deste pressuposto, importa compreender como pode a interpretação contribuir para a sustentabilidade das atrações e dos destinos turísticos. Com base numa revisão da literatura publicada nas últimas duas décadas, procurou-se conhecer o estado da arte da sustentabilidade aplicada à área do turismo, identificando as dimensões que lhe têm vindo a ser atribuídas. Atendendo, em particular, à dimensão económica, percebe-se, através deste estudo exploratório e de caracter conceptual, que a relação entre a interpretação e a sustentabilidade económica é uma área de estudo ainda muito pouco explorada.

description: In [Phys. Rev. Lett. 95, 080502 (2005)], Zheng proposed a scheme for implementing a conditional phase shift via adiabatic passages. The author claims that the gate is "neither of dynamical nor geometric origin" on the grounds that the Hamiltonian does not follow a cyclic change. He further argues that "in comparison with the adiabatic geometric gates, the nontrivial cyclic loop is unnecessary, and thus the errors in obtaining the required solid angle are avoided, which makes this new kind of phase gates superior to the geometric gates." In this Comment, we point out that geometric operations, including adiabatic holonomies, can be induced by noncyclic Hamiltonians, and show that Zheng's gate is geometric. We also argue that the nontrivial loop responsible for the phase shift is there, and it requires the same precision as in any adiabatic geometric gate.

description: Este artigo pretende demonstrar que o regresso dos emigrantes portugueses pode contribuir para o desenvolvimento rural, através do setor do turismo. Este argumento é válido ao considerar‑se que o movimento emigração‑regresso tem um impacto positivo no desenvolvimento das áreas mais carenciadas e que o setor do turismo pode criar mais emprego e rendimento comparativamente com outros setores da economia. Os resultados obtidos num estudo realizado em Portugal, através da aplicação de um inquérito por questionário a 5.157 emigrantes portugueses, corroboram esta argumentação. Concluiu‑se, que são os emigrantes em idade ativa e com residência numa área rural que mais dispõem de formação e experiência profissional na área do turismo e de capital para investir num negócio, bem como maior propensão para regressar, investir e ter um emprego nesta área em Portugal.

Conformal Field Theory with Two Kinds of Bosonic Fields and Two Linear Dilatons
Creators: name: Kamani, Davoud
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider a two-dimensional conformal field theory which contains two kinds of the bosonic degrees of freedom. Two linear dilaton fields enable us to study a more general case.

description: Coniella Höhn., Ber. Deutsch. Bot. Ges. 36: 316 (1918)
Index Fungorum number: IF7753
Type species: Coniella pulchella Höhn., Berichte der Deutschen Botanischen Gesellschaft 36: 316 (1918).
Notes: Monotypic genus Coniella was originally established and typified by Co. pulchella, and later it was accommodated in Schizoparmaceae (Diaporthales) based on multi-gene phylogenetic analyses and morphology (Von Höhnel 1918, Rossman et al. 2007). Currently, 58 accepted species are listed in Species Fungorum (2023). The sexual morph of Coniella was described by having solitary, globose ascomata, coriaceous, papillate with periphysate ostiole in the middle, unitunicate, clavate to subcylindrical asci, with “J-” apical ring, hyaline to pale brown and ellipsoidal ascospores (Hyde et al. 2020, Tennakoon et al. 2021). The asexual morph of Coniella is described as producing hyaline, olivaceous brown to brown, unicellular, thin- to thick-walled, ellipsoid, globose, smooth, napiform, fusiform or naviculate conidia (Tennakoon et al. 2021). Species of Coniella are often reported as pathogens, endophytes, and saprobes on fruits, leaves, roots, and stems of a wide variety of woody and herbaceous plants, or in soil (Tennakoon et al. 2021).

description: No território da Comunidade para o Desenvolvimento da África Austral (SADC) as Áreas Transfronteiriças de Conservação, representam uma vasta zona ecológica que se estende por dois ou mais países, integrando diversas áreas protegidas. Trata-se de um território único que foi fragmentado pela divisão imposta pelas potências colonizadoras constituindo um importante recurso para atividade turística. Este estudo consiste numa abordagem crítica sobre as Áreas Transfronteiriças de Conservação da SADC, focando fundamentalmente a Área Transfronteiriça de Conservação Okavango Zambeze. Por outro lado pretende refletir-se sobre de que forma o desenvolvimento turístico na área transfronteiriça de conservação em estudo poderá ser um fator de desenvolvimento do território, inclusão das comunidades rurais, de estabilização e de paz.

description: Este estudo tem como objetivo prioritário investigar a importância da ética empresarial para os empreendimentos hoteleiros de São Luís do Maranhão, Brasil, no que tange a realização de ações ambientalmente sustentáveis. Os objetivos específicos deste trabalho consistem em realizar um estudo conceitual sobre sustentabilidade ambiental, sistemas de gestão ambiental e ética, pesquisar hotéis da orla de São Luís para averiguar suas preocupações ao exercer ações sustentáveis e sugerir direcionamentos para o comportamento ético dos gestores com relação a práticas sustentáveis. Este estudo é exploratório, qualitativo e descritivo (Richardson, 1999). A metodologia utilizada fundamentou‑se em uma pesquisa bibliográfica sobre turismo, sustentabilidade ambiental, economia e filosofia, e num trabalho de campo, por meio do qual foi possível verificar uma realidade de interação problemática entre os referidos hotéis e o meio ambiente identificando divergências entre os interesses prioritários dos gestores quanto ao desenvolvimento de ações sustentáveis. Constatou‑se que as ações de preocupação ambiental empreendidas pelos hotéis são inexpressivas diante da amplitude que poderiam ter enquanto agentes de modificação social.

description: The article examines cruise tourism from the point of view of the possibility of ensuring the recreation and the tourism development in the urban environment and city agglomeration. The foreign experience in the organization of river cruises is briefly reviewed. The article demonstrates significant potential of the hydrographic network of Volga Federal District in general, as well as city agglomerations of the Republic of Tatarstan in particular. The period of the pandemic showed the demand among people for short trips along rivers and lakes within the city, city agglomeration and region. However, such voyages tend to be out of the question for water cruises. The article proposes and defines the term “mini cruise” to refer to travel less than 24 hours. The role of mini-cruises in local socio-economic life is shown. The Republic of Tatarstan has all the necessary factors to expand the range of river cruises, incl. minicruises: a wide range of natural factors, incl. an extensive hydrographic network; interesting coastal areas, different historical, cultural and modern objects and events, intangible heritage; a historically established shipbuilding industry that includes large industrial enterprises, small businesses and craft initiatives. Further study of the potential of mini-cruises and their inclusion in the orbit of cruise tourism will help to solve issues in meeting the recreational needs of people and in creating new tourism products, and, therefore, developing the local economy.
