description: In this paper we revisit the well-known technique of predicate abstraction to characterise performance attributes of system models incorporating probability. We recast the theory using expectation transformers, and identify transformer properties which correspond to abstractions that yield nevertheless exact bound on the performance of infinite state probabilistic systems. In addition, we extend the developed technique to the special case of "data independent" programs incorporating probability. Finally, we demonstrate the subtleness of the extended technique by using the PRISM model checking tool to analyse an infinite state protocol, obtaining exact bounds on its performance.

description: Consider the classical XY model in a weak random external field pointing along the $Y$ axis with strength $ε$. We study the behavior of this model as the range of the interaction is varied. We prove that in any dimension $d \geq 2$ and for all $ε$ sufficiently small, there is a range $L=L(ε)$ so that whenever the inverse temperature $β$ is larger than some $β(ε)$, there is strong residual ordering along the $X$ direction.

description: We study time-bounded reachability in continuous-time Markov decision processes for time-abstract scheduler classes. Such reachability problems play a paramount role in dependability analysis and the modelling of manufacturing and queueing systems. Consequently, their analysis has been studied intensively, and techniques for the approximation of optimal control are well understood. From a mathematical point of view, however, the question of approximation is secondary compared to the fundamental question whether or not optimal control exists. We demonstrate the existence of optimal schedulers for the time-abstract scheduler classes for all CTMDPs. Our proof is constructive: We show how to compute optimal time-abstract strategies with finite memory. It turns out that these optimal schedulers have an amazingly simple structure - they converge to an easy-to-compute memoryless scheduling policy after a finite number of steps. Finally, we show that our argument can easily be lifted to Markov games: We show that both players have a likewise simple optimal strategy in these more general structures.
A study of the influence of the gauge group on the Dyson-Schwinger equations for scalar-Yang-Mills systems

description: The particular choice of the gauge group for Yang-Mills theory plays an important role when it comes to the influence of matter fields. In particular, both the chosen gauge group and the representation of the matter fields yield structural differences in the quenched case. Especially, the qualitative behavior of the Wilson potential is strongly dependent on this selection. Though the algebraic reasons for this observation is clear, it is far from obvious how this behavior can be described besides using numerical simulations. Herein, it is investigated how the group structure appears in the Dyson-Schwinger equations, which as a hierarchy of equations for the correlation functions have to be satisfied. It is found that there are differences depending on both the gauge group and the representation of the matter fields. This provides insight into possible truncation schemes for practical calculations using these equations.

The father of his country, being a brief study of the intersection of fatherhood and the rhetoric of state power in the late Republic and early Principate of Rome
Creators: name: Buchanan, Marshall Calvin
Publisher: name: University of British Columbia
Year: 2016

description: This thesis explores the intersection of the Roman conception of the state’s authority and the notion of fatherhood during the late Republic and early Principate. Its general conclusion is that the state’s authority in both periods was conceived of, in varying degrees, as patria potestas, which is the statutorily granted but legally unfettered power of the pater familias (Roman male head of household) over his dependents and property. It draws this conclusion first by defining fatherhood primarily in terms of patria potestas. It then examines two key works of the Republican statesman Cicero. In his De Re Publica, Cicero proposes the state as a transcendent institution whose justification is the human capacity to use reason (ratio). But both in this work and in the later De Officiis, he also formulates an account of the state that links it to patria potestas. I term these two types of state the civic patria and natal patria respectively. The close association of the two models of statehood is exemplified by the title which Cicero coined in 63 B.C., ‘Pater Patriae’ (“father of the fatherland,” sometimes also ‘Parens Patriae,’ “parent of the fatherland”). Prefatory to examining the state’s authority under the Principate, this thesis briefly considers the change in the relationship between state and family under the reign of Augustus. It finds that, from c. 23 B.C., the household of Augustus gradually became identical with the state, and Augustus ruled the empire as a pater familias with patria potestas. Finally, taking Seneca as an imperial analog to Cicero, this thesis analyzes Seneca’s panegyric and kingship treatise addressed to Nero, De Clementia. It finds that Seneca can portray the childless emperor as a father because his power as emperor is conceived as being one and the same with patria potestas. The emperor’s role as national pater familias defines his relation in three key areas: with the laws, the universal order, and his people.

description: Integrated chemical production sites consist of several plants linked via materials, logistics, energy, and infrastructure. A methodology is developed to quantify economic and environmental aspects of integration and applied to actual cases from industry. Integration potential, the suitability of a plant to be integrated, is proposed based on key process characteristics. This approach may aid in the planning of locations and capacities for chemicals production in consideration of process type.

description: Dijet angular distributions from the first LHC pp collisions at center-of-mass energy sqrt(s) = 7 TeV have been measured with the ATLAS detector. The dataset used for this analysis represents an integrated luminosity of 3.1 pb-1. Dijet $χ$ distributions and centrality ratios have been measured up to dijet masses of 2.8 TeV, and found to be in good agreement with Standard Model predictions. Analysis of the $χ$ distributions excludes quark contact interactions with a compositeness scale $Λ$ below 3.4 TeV, at 95% confidence level, significantly exceeding previous limits.

Publisher: name: Journal of Tourism & Development
Year: 2021

description: The desire to achieve success is currently a daily concern for any company, but it is not always explicitly described and defined. For this reason, measuring performance is essential to transform the complex reality of business into explicit and concrete concepts, which can be easily implemented. One of the most popular approaches to performance measurement is the identification of Critical Success Factors (CSFs). Within the hotel industry, performance measurement is increasingly important due to the growing importance of the value of human resources and competitiveness, which implies constantly looking for ways to improve the level of quality, reputation, and increase profit. The studies applied to this specific sector are relatively scarce, especially regarding hotel establishments of the "pousada" type. Thus, the main objective of this investigation is to identify and analyze the most critical success factors for Pestana Pousadas de Portugal and the respective key performance indicators (KPIs). The applied methodology went through a fusion of all the information reviewed in the literature and resulted in the formulation of three dimensions of analysis. These elements were included in the data collection instrument. The data collection granted to obtain 19 personal interviews addressed to the directors and managers of Pousadas de Portugal. The analysis of the data allowed to conclude that the most important objective in the opinion of the respondents is customer satisfaction. In general, the resulting set of the most important CSFs corroborates the set of most prominent CSFs in the literature. In terms of KPIs, respondents proposed several indicators, including financial and non-financial indicators.

description: Olive-oil tourism is an emergent segment in tourism that represents a panoply of tourism activities based on the olive-oil, the olive and the olive tree, with particular expression in the Mediterranean Basin. Although Portugal is part of this region, the study and promotion of olive-oil tourism in the country is almost null. The aim of this study is to identify the elements which confer development bases for the segment in Portugal and to contextualize the current supply. The results are based on the data collection through the search engine Google and the institutional websites of the PDO regions’ municipalities. It was possible to identify seven main formats of supply (museum spaces, visitable production spaces, events, routes, activities in accommodations, tourism recreation and specialized shops) as well as several fragilities and guidelines for the segment in Portugal.

Ecotouristic Networks and Semiosphere

Year: 2021

description: This study analyzes the Route of Emotions under the approach of Yuri Lotman's semiosphere concept. The methodology consisted of a literature review with a qualitative approach. Data were collected through non-participant observation. It was concluded that the relationship structure of the semiosphere is complex, with greater permeability in the external borders, leading to the peripheralization of its geographical center. Communication is most active between the nucleus, spatially dispersed at the extremities. As they move to the periphery, communication weakens. The poles maintain dextrohemispheric tendencies and the peripheries, sinister-hemispheric, which justifies greater capacity of creation of the poles. The challenge is to integrate the semiosphere subsystems.

description: Indirect exposure assessment based on average environmental concentrations in microenvironments and time spent in each environment has been considered an important way of assessing personal exposure to air pollutants. Using this indirect approach, the exposure simulator generates personal exposure values or the distribution of personal exposure for air pollutants. To match the simulator with the actual exposure measurements well, some calibration is necessary. However, unlike simulators generating personal exposure values, research evaluating the validity of the second type of simulator is rare. This study aims to develop a method for calibrating a simulator that generates an exposure distribution. To describe the relationship between the actual exposure measurements and the simulator, we introduce measurement error models (MEMs) and explain how the coefficients in the models can be used for calibrating the exposure distribution. We illustrate the proposed method using a Korea Simulation Exposure Model for fine particulate matter (KoSEM-PMII).

description: We present a new tool, GPA, that can generate key performance measures for very large systems. Based on solving systems of ordinary differential equations (ODEs), this method of performance analysis is far more scalable than stochastic simulation. The GPA tool is the first to produce higher moment analysis from differential equation approximation, which is essential, in many cases, to obtain an accurate performance prediction. We identify so-called switch points as the source of error in the ODE approximation. We investigate the switch point behaviour in several large models and observe that as the scale of the model is increased, in general the ODE performance prediction improves in accuracy. In the case of the variance measure, we are able to justify theoretically that in the limit of model scale, the ODE approximation can be expected to tend to the actual variance of the model.

description: The effects of pinning between fluxoids and vortices in the core of a neutron star, on the dynamics of the core neutron superfluid are considered. The pinning impedes, but does not absolutely block, any radial as well as {\em azimuthal} motion of the neutron vortices with respect to the lattice of fluxoids. The time scale for the coupling of rotation of the core superfluid to the rest of the star is calculated, allowing for the effect of the finite frictional force on the neutron vortices due to their pinning with the fluxoids. This turns out to be the dominant mechanism for the coupling of the core of a neutron star to its crust, as compared to the role of electron scattering, for most cases of interest. Furthermore, different behaviors for the post-glitch response of the core superfluid are distinguished that might be tested against the relevant observational data. Also, a conceptually important case (and controversial too, in the earlier studies on the role of the crustal superfluid) is realized where a superfluid may remain decoupled in spite of an spinning up of its vortices.

Experiences of metanoia : the relationship between second language acquisition and metanoia
Creators: name: Ranson, Samantha Kelly
Publisher: name: University of British Columbia
Year: 2016

description: This qualitative study explores the connection between Second Language Acquisition (SLA) and metanoia in a post-secondary level English for Academic Purposes (EAP) program. Taken from Ancient Greek philosophy, metanoia refers to a fundamental shift in habits of the mind. Until now, the connection between metanoia and second language learning has not been fully examined, particularly in higher education contexts. The objective of this study is to examine the progression of metanoia in the SLA of International students enrolled in an EAP program. Specifically, the research question for this study was: How do EAP students experience metanoia, and what is the relationship with their second language acquisition? Qualitative methods were used throughout this study. The study combined both an online survey and follow-up interview to collect data, which was triangulated to analyze the data. A socio-cognitive theoretical framework supported the conception of the study and the analysis of the data. The data indicated that the best way for EAP students to acquire academic English language skills is to be taught as a “whole” learner (paying attention to the social, emotional, cultural, and academic needs of the student). From the interviews and surveys, six prominent themes were found throughout: growth, learning process, communication, emotions, relationship, and resources. Participants expressed that their academic and social success was related to these themes. It is possible that these experiences were the catalysts to their personal experiences of metanoia. This study provides insight into the lives of English language learners and how to improve or change the EAP environment. The results could assist EAP instructors in seeing differences between local and international education systems and the learning patterns of different students, thus aiding students in reaching moments of metanoia with the information and assistance of their EAP instructors.

description: A series of experiments in stationary and moving passenger railcars was conducted to measure the removal rates of particles in the size ranges of SARS-CoV-2 viral aerosols, and the air changes per hour provided by the existing and modified air handling systems. The effect of ventilation and air filtration systems on removal rates and their effects on estimated probability (i.e., risk) of infection was evaluated in a range of representative conditions: (1) for two different ratios of recirculated air (RA) to outdoor air (OA) (90:10 RA:OA and 67:33 RA:OA); (2) using minimum efficiency reporting value (MERV) filters with standard (MERV-8) and increased (MERV-13) filtration ratings; and (3) in the presence and absence of a portable high-efficiency particulate-air (HEPA) room air purifier system operated at clean air delivery rate (CADR) of 150 and 550 cfm. The higher-efficiency MERV-13 filters significantly increased particle removal rates on average by 3.8 to 8.4 hr−1 across particle sizes ranging from 0.3 to 10 µm (p < 0.01) compared to MERV-8 filters. The different RA:OA ratios and the use of a portable HEPA air purifier system had little effect on particle removal rates. MERV-13 filters reduced the estimated probability of infection by 42% compared to the MERV-8 filter. The use of a HEPA-air purifier with a MERV-13 filter causes a 50% reduction in the estimated probability of infection. Upgrading the efficiency of HVAC filters from MERV-8 to MERV-13 in public transit vehicles is the most effective exposure control method resulting in a clear reduction in the removal rates of aerosol particles and the estimated probability of infection.

description: We investigate the structure of two point functions for the QFT dual to an asymptotically Lorentzian AdS-wormhole. The bulk geometry is a solution of 5-dimensional second order Einstein Gauss Bonnet gravity and causally connects two asymptotically AdS space times. We revisit the GKPW prescription for computing two-point correlation functions for dual QFT operators O in Lorentzian signature and we propose to express the bulk fields in terms of the independent boundary values phi_0^\pm at each of the two asymptotic AdS regions, along the way we exhibit how the ambiguity of normalizable modes in the bulk, related to initial and final states, show up in the computations. The independent boundary values are interpreted as sources for dual operators O^\pm and we argue that, apart from the possibility of entanglement, there exists a coupling between the degrees of freedom leaving at each boundary. The AdS_(1+1) geometry is also discussed in view of its similar boundary structure. Based on the analysis, we propose a very simple geometric criterium to distinguish coupling from entanglement effects among the two set of degrees of freedom associated to each of the disconnected parts of the boundary.

description: We analyze the organization, promotion and public perception of V-day, a political rally that took place on September 8, 2007, to protest against corruption in the Italian Parliament. Launched by blogger Beppe Grillo, and promoted via a word of mouth mobilization on the Italian blogosphere, V-day brought close to one million Italians in the streets on a single day, but was mostly ignored by mainstream media. This article is divided into two parts. In the first part, we analyze the volume and content of online articles published by both bloggers and mainstream news sources from June 14 (the day V-day was announced) until September 15, 2007 (one week after it took place) . We find that the success of V-day can be attributed to the coverage of bloggers and small-scale local news outlets only, suggesting a strong grassroots component in the organization of the rally. We also find a dissonant thematic relationship between content published by blogs and mainstream media: while the majority of blogs analyzed promote V-day, major mainstream media sources critique the methods of information production and dissemination employed by Grillo. Based on this finding, in the second part of the study, we explore the role of Grillo in the organization of the rally from a network analysis perspective. We study the interlinking structure of the V-day blogosphere network, to determine its structure, its levels of heterogeneity, and resilience. Our analysis contradicts the hypothesis that Grillo served as a top-down, broadcast-like source of information. Rather, we find that information about V-day was transferred across heterogeneous nodes in a moderately robust and resilient core network of blogs. We speculate that the organization of V-day represents the very first case, in Italian history, of a political demonstration developed and promoted primarily via the use of social media on the web.

description: Os conselhos de políticas públicas são órgãos que auxiliam a governança de um destino turístico, possibilitando a discussão de temas, nem sempre contemplados nas agendas governamentais. Diante dessa realidade, tomando-se como referência a governança turística de Socorro, São Paulo, Brasil e o binômio sustentabilidade e acessibilidade, o presente estudo buscou identificar como o Conselho Municipal de Turismo da Estância de Socorro e outros atores envolvidos com a governança turística local abordam a gestão da sustentabilidade e da acessibilidade pela perspectiva de resultados. Para tanto, valeu-se dos procedimentos metodológicos: pesquisa-diagnóstico, triangulação de dados e análise de conteúdo. Os resultados apontaram que no âmbito da gestão da acessibilidade em Socorro, a governança está no nível das ações, reconhecendo-se esta gestão como já consolidada. A gestão da sustentabilidade, por sua vez, está no nível das proposições e ações, em um processo de construção.

description: Cloth masks are a tool for controlling community transmission during pandemics, as well as during other outbreak situations. However, cloth masks vary in their designs, and the consequences of this variability for their effectiveness as source control have received little attention, particularly in terms of user discomfort and problematic mask-wearing behaviors. In the present studies, common design parameters of cloth masks were systematically varied to ascertain their effect(s) on the subjective discomfort and frequency of problematic mask-wearing behaviors, which detract from the effectiveness of cloth masks as source control. The type of fabric comprising a mask (flannel or twill made of 100% cotton) and the attachment-style of a mask (i.e., ear loops or fabric ties) were varied in adults (18 to 65 years) and children (ages 6 to 11 years). For adults, ear loops were less comfortable than ties (p = .035) and were associated with greater face- (p = .005) and mask-touching (p = .001). Children, however, found flannel masks to be more breathable than twill masks (p = .007) but touched their masks more frequently when wearing a mask made of flannel than twill (p = .033). Common design parameters of cloth masks not only affect user discomfort and behavior but do so differently in adults and children. To improve the effectiveness of cloth masks as source control, the present studies highlight the importance of measuring the effect(s) of design decisions on user discomfort and behavior in different populations.

description: A series of experiments in stationary and moving passenger railcars was conducted to measure the removal rates of particles in the size ranges of SARS-CoV-2 viral aerosols, and the air changes per hour provided by the existing and modified air handling systems. The effect of ventilation and air filtration systems on removal rates and their effects on estimated probability (i.e., risk) of infection was evaluated in a range of representative conditions: (1) for two different ratios of recirculated air (RA) to outdoor air (OA) (90:10 RA:OA and 67:33 RA:OA); (2) using minimum efficiency reporting value (MERV) filters with standard (MERV-8) and increased (MERV-13) filtration ratings; and (3) in the presence and absence of a portable high-efficiency particulate-air (HEPA) room air purifier system operated at clean air delivery rate (CADR) of 150 and 550 cfm. The higher-efficiency MERV-13 filters significantly increased particle removal rates on average by 3.8 to 8.4 hr−1 across particle sizes ranging from 0.3 to 10 µm (p < 0.01) compared to MERV-8 filters. The different RA:OA ratios and the use of a portable HEPA air purifier system had little effect on particle removal rates. MERV-13 filters reduced the estimated probability of infection by 42% compared to the MERV-8 filter. The use of a HEPA-air purifier with a MERV-13 filter causes a 50% reduction in the estimated probability of infection. Upgrading the efficiency of HVAC filters from MERV-8 to MERV-13 in public transit vehicles is the most effective exposure control method resulting in a clear reduction in the removal rates of aerosol particles and the estimated probability of infection.

description: Since very early in history, events are a constant in civilization and manifest themselves as a form of cultural expression for a specific community. For this reason, they are used as key attractions to differentiate the destinations from their competitors and to gain competitive advantage. The event industry has been growing and with this its importance, both for destinations and for the local communities. Moreover, the constant change and evolution of the industry, it becomes essential to events' companies to be prepared to identify, measure, and develop strategies to overcome potential risks and, know-how to act in situations that could bring negative consequences to the organization. Thus, this research aims to understand How do companies of congresses and events in Portugal react and operate when faced with a period of risk. Through a quantitative methodology, supported by a questionnaire this research focuses on the analysis of the risk strategies or plans that companies have implemented, what factors they use to detect the risk and whether they consider the state's help enough to face the current risk situation. One of the main conclusions refers that a major part of the companies have implemented a risk plan, and that state's help is considered insufficient to overcome this hard period.

description: The WMAP 7-year temperature maps have been re-analized to extract a CMB map and CMB power spectrum with reduced contamination by astrophysical foregrounds and noise. The method used is based on linear combinations of WMAP data and foreground templates, implemented on a decomposition of the observations onto a needlet frame. We obtain a clean CMB map with low contamination from foregrounds and noise, as well as a new estimate of the CMB temperature power spectrum. The latter is essentially compatible with the power spectrum published by the WMAP collaboration, although it is slightly but systematically lower on large scales. The exact origin of this discrepancy is not clear.

description: To evaluate if wayfinding can be considered as an innovative practice in the prevention of overtourism, a Systematic Literature Review (SLR) was used at first. This stage intended to map, characterize and synthesize documents published in the Scopus database that approached innovation, tourism and wayfinding. The reduced number of publications found, together with the results of these studies that indicated the use of wayfinding as a corrective strategy to problems related to tourism activity, allowed to suggest its application as an innovative practice in the prevention of overtourism.

description: Sono almeno dieci anni che scrittori e critici riflettono sulle residue possibilità di esperienza concesse alla narrazione nel mondo contemporaneo. La letteratura dell’inesperienza, com’è noto, era il titolo di un fortunato pamphlet (2006) di Antonio Scurati, che ha lasciato traccia anche in saggi più recenti come Senza trauma di Daniele Giglioli. Non a caso, Scurati ha studiato le rappresentazioni letterarie della guerra, scrivendo a sua volta fiction su quel tema: la guerra è infatti l’esperienza, in senso antropologico prima ancora che letterario, di cui le narrazioni di ogni tempo hanno dato e continuano a dare conto.

Stories of hope : a community endeavor to promote college access with rural youths in Benue state of Nigeria

description: This study is about understanding the experiences of some of the youths who participated in the NeboReach Youth Empowerment Project (NYEP) and their parents, and how their experiences inform the understanding of the researcher, of her own experiences with regards to educational access, and the interpretations of those experiences retrospectively. The NYEP was initiated by the researcher in 2005 in Katsina-Ala, a rural town in Benue State of Nigeria with the goal to promote access to tertiary education for out of school secondary school leavers who aspire to further their education. The motivation for initiating the project was enhanced by the fact that the researcher had experienced some difficulties with educational access as a girl-child in a Nigerian rural town of Kwajafa, in the 1960’s. Eighteen youths participated in the NYEP in a span of 10 years (2005-2014). After six years of operation, there was an evidence of a positive appraisal for the project, as the researcher continued to receive texts while in Vancouver from youths in Katsina-Ala who wanted to enrol in the project for the first time. This suggested that there was a need for the project to continue, and to expand. Hence feedback from NYEP youth participants and their parents, regarding the relevance of the project became crucial. The auto-ethnography method was used in this study, and data was collected through reflexive dyadic interviews with six youths and five parents. The community leader also participated in the study. Other sources of data were used—such as journal entries, informal conversations, photographs and videos. The researcher’s experience, with regards to accessing tertiary education was also considered as part of the data. Research participants’ informal conversations with the researcher were regarded as valuable sources of data as the formal interviews. The findings revealed that the greatest hurdles the NYEP youths faced, and are still facing in terms of accessing tertiary education are associated with poverty (both of financial resources and money generating ideas), corruption and rural living. All youths said that NYEP helped them—some to access tertiary education and others to establish their businesses—and for some, both.

description: One of the most common running related injuries and leading cause of lateral knee pain in recreational runners is iliotibial band syndrome (ITBS). The popularity of recreational running and rate of running related injuries are increasing. This study’s goals were to evaluate the effects of three different exercises programs in reducing ITBS symptoms and determine if the experimental exercise group program provides a new progressive rehab intervention for ITBS management. This study consisted of volunteer female distance runners age 19-45 with ITBS—with a 10-mile per week average running distance during a three-month period. After recording age, gender, injured leg, pain, body weight, and height the participants were split into three treatment groups: i) an experimental exercise group, ii) a conventional exercise group, and iii) a stretching group. Outcomes measured were the Y Balance test (YBT), single leg mini squats (SLMS), dynamometer readings (DN), lower extremity functional scale (LEFS), and numeric pain rating scale (NPRS). The YBT, SLMS and LEFS were taken at weeks 0 and 8, hip strength DN measurements were taken biweekly and the NPRS was taken weekly for 8-weeks. Hypothetically the experimental exercise group should exhibit similar or greater improvements in ITBS symptoms compared to current researched programs for hip strength and stretching. A two-way factorial, repeated measures, analysis of variance (ANOVA) model examined the effects each exercise program had on the outcome measures for between and within group’s differences. Statistical significance within the experimental group was determined for the composite YBT and DN measurements for injured and non-injured leg, injured leg for the posterior medial reach for the YBT, LEFS questionnaire, NPRS during running activity and the SLMS. Statistical significance was determined between the stretching and experimental exercise groups. The stretching group exhibited statistically significant YBT anterior reach for the injured/non-injured leg and the LEFS questionnaire. Although there were no statistical differences found for the experimental exercises group, it consistently showed improvements in outcome measures and never scored less than the other two groups.

description: This article will address the importance of risk management plans for travel agencies and tour operators and present the mechanisms that can be used to better manage in times of crisis. Throughout it, the importance of the travel agency sector in the tourism sector will be analyzed, the risk management plans that can be adopted by them and the measures that can be taken to reduce the risk and the consequences that could arise in a situation of crisis. The characteristics of Portuguese companies in this sector will also be analyzed, to make a better understanding of the mechanisms that are used by them and new ones that can be adopted in the future to reduce the difficulties they face at these times. It was adopted a quantitative methodology supported by a questionnaire conducted to Portuguese travel agencies and tour operators, which obtained 221 responses. It was concluded that risk management plans are a viable option to be adopted by travel agencies and tour operators, although it is still not very common in Portugal.
