description: A minimal representation of the N = 8 extended worldline supersymmetry, known as the `ultra-multiplet', is closely related to a family of supermultiplets with the same, E(8) chromotopology. We catalogue their effective symmetries and find a Spin(4) x Z(2) subgroup common to them all, which explains the particular basis used in the original construction. We specify a constrained superfield representation of the supermultiplets in the ultra-multiplet family, and show that such a superfield representation in fact exists for all adinkraic supermultiplets. We also exhibit the correspondences between these supermultiplets, their Adinkras and the E(8) root lattice bases. Finally, we construct quadratic Lagrangians that provide the standard kinetic terms and afford a mixing of an even number of such supermultiplets controlled by a coupling to an external 2-form of fluxes.

description: We describe the methodology required for estimation of photometric estimates of metallicity based on the SDSS gri passbands, which can be used to probe the properties of main-sequence stars beyond ~ 10 kpc, complementing studies of nearby stars from more metallicity-sensitive color indices that involve the u passband. As a first application of this approach, we determine photometric metal abundance estimates for individual main-sequence stars in the Virgo Overdensity, which covers almost 1000 square degrees on the sky, based on a calibration of the metallicity sensitivity of stellar isochrones in the gri filter passbands using field stars with well-determined spectroscopic metal abundances. Despite the low precision of the method for individual stars, internal errors of in [Fe/H] ~ +/- 0.1 dex can be achieved for bulk stellar populations. The global metal abundance of the Virgo Overdensity determined in this way is = -2.0 +/- 0.1 (internal) +/- 0.5 (systematic), from photometric measurements of 0.7 million stars with heliocentric distances from ~ 10 kpc to ~ 20 kpc. A preliminary metallicity map, based on results for 2.9 million stars in the northern SDSS DR-7 footprint, exhibits a shift to lower metallicities as one proceeds from the inner- to the outer-halo population, consistent with recent interpretation of the kinematics of local samples of stars with spectroscopically available metallicity estimates and full space motions.

AN ANALYSIS OF THE CURRENT GREEK TRAVEL AGENCIES POLICY ON RECRUITMENT, DUTIES, ONGOING TRAINING AND EMPLOYEE ADVANCEMENT
Creators: name: Papageorgiou, Athina
Publisher: name: tourismos
Year: 2016

description: Our aim was to record a variety of aspects concerning personnel selection, employment status and education of the staff of the Greek travel agencies. We found that the current economic crisis affected personnel selection and management and Greek travel agencies tend to hire younger and more educated staff using correct and just hiring criteria. Agencies offer limited further education and specialization and do not sufficiently motivate their employees to increase their productivity, probably as a result of recession. We also found that when Greek travel agencies dismiss their staff they do it after a fair judgment. As responders did not refer to business developmental strategy and how it could affect personnel hiring, education, duties and employee’s advancement, further studies are needed to clarify these subjects.

description: We study the effects of higher-order deformations $β_λ$ ($λ=4,6,8,$ and $10$) on the ground state properties of superheavy nuclei (SHN) near the doubly magic deformed nucleus $^{270}$Hs by using the multidimensionally-constrained (MDC) relativistic mean-field (RMF) model with five effective interactions PC-PK1, PK1, NL3$^{*}$, DD-ME2, and PKDD. The doubly magic properties of $^{270}$Hs are featured by the large energy gaps at $N=162$ and $Z=108$ in the single-particle spectra. By investigating the binding energies and single-particle levels of $^{270}$Hs in multidimensional deformation space, we find that the deformation $β_6$ has the greatest impact on the binding energy among these higher-order deformations and influences the shell gaps considerably. Similar conclusions hold for other SHN near $^{270}$Hs. Our calculations demonstrate that the deformation $β_6$ must be considered when studying SHN by using MDC-RMF.

description: We analyze electronic, magnetic, and structural properties of the spinel compound MgTi$_2$O$_4$ using the local density approximation+U method. We show how MgTi$_2$O$_4$ undergoes to a canted orbital-spin ordered state, where charge, spin and orbital degrees of freedom are frozen in a geometrically frustrated network by electron interactions. In our picture orbital order stabilize the magnetic ground state and controls the degree of structural distortions. The latter is dynamically derived from the cubic structure in the correlated LDA+U potential. Our ground-state theory provides a consistent picture for the dimerized phase of MgTi$_2$O$_4$, and might be applicable to frustrated materials in general.

description: We present a detailed description of our void finding algorithm which is an extension of the prescription by Hoyle and Vogeley (2002). We include a discussion of the reproducibility and robustness of the algorithm as well as the statistical significance of the detected voids. We apply our void finder to the Data Release 5 (DR5) of the Sloan Digital Sky Survey (SDSS) and identify 232 cosmological voids. A void catalog which contains the most salient properties of the detected voids is created. We present a statistical analysis of the distribution of the size, shape and orientation of our identified cosmological voids. We also investigate possible trends with redshift for 0.04 < z < 0.16. We compare our results to those from an identical analysis of a mock catalog based on the LambdaCDM model and find reasonable agreement. However, some statistically significant differences in the overall orientation of cosmological voids are present and will have to be reconciled by further refinement of the simulations.

description: In the last decade, the role of shearing loads has been increasingly suspected to play a determinant impact in the formation of deep pressure ulcers. In vivo observations of such deformations are complex to obtain. Previous studies only provide global measurements of such deformations without getting the quantitative values of the loads that generate these deformations. To study the role that shearing loads have in the aetiology of heel pressure ulcers, an MR-compatible device for the application of shearing and normal loads was designed. Magnetic resonance imaging is a key feature that allows to monitor deformations of soft tissues after loading in a non-invasive way. Measuring applied forces in an MR-environment is challenging due to the impossibility to use magnetic materials. In our device, forces are applied through the compression of springs made in polylactide. Shearing and normal loads were applied on the plantar skin of the human heel by means of an indenting plate while acquiring MR images. The device materials did not introduce any imaging artifact and allowed for high quality MR measurements permitting to identify the deformation of the internal components of the heel. The obtained subject-specific results are an original data set that can be used in validations for Finite Element analysis and therefore contribute to a better understanding of the factors involved in pressure ulcer development.

The process conditions used have been chosen so as to avoid any significant damage to the nanotube structure. The type and level of functionalization, the location of the grafted functions on the surface of the nanotube and the changes in morphological characteristics of the samples were examined by using a wide and complementary range of analytical techniques. We propose an explanation for the differences in the oxidizing action of sulfuric and nitric acids. The combined results allow us to suggest possible reaction mechanisms that occur on the surface of the nanotube.

Publisher: name: tourismos
Year: 2016

description: This research was conducted to investigate the multi factor process to create positive Word-of-Mouth communication in connection for improved destination branding. Destination brand personality and tourism services have a significant role in the domain of destination marketing. Although the concept of brand personality has been brought from the domain of tangible product marketing but it has an equally important role in tourism marketing as well. In the present study the author has proposed a structural framework that depicts the interrelationship among brand personality and tourism services the resultant overall satisfaction from destination brand experience; which in turn leads generate WOM communication- the most effective tool for tourism. The research was conducted with 406 Indian tourists sample collected from different parts of India. A structural equation modeling has been done to validate the proposed model. The outcome of this research paper should enable destination marketers and tourism brand managers to get a new direction in their thought, the outcome would also be helping further researchers to think in this direction.

description: Background Comprehensive Geriatric Assessment (CGA) is a multidimensional interdisciplinary process that addresses an older adult’s biopsychosocial capabilities to create an integrated and co-ordinated plan of care. While quantitative evidence that demonstrates the positive impacts of CGA on clinical and process outcomes has been synthesised, to date qualitative research reporting how older adults and service providers experience CGA has not been synthesised. This study aimed to systematically review and synthesise qualitative studies reporting community-dwelling older adults’, caregivers’ and healthcare professionals’ (HCP) experiences of CGA in the primary care and out-patient (OPD) setting. Method We systematically searched fve electronic databases including MEDLINE, CINAHL, PsycINFO, PsycARTICLES and Social Sciences Full Text targeting qualitative or mixed methods studies that reported qualitative fndings on older adults’, caregivers’ and HCPs’ experiences of CGA in primary care or out-patient settings. There were no language or date restrictions applied to the search. The protocol was registered with the PROSPERO database (Registration: CRD42021283167). The methodological quality of the included studies was appraised using the Critical Appraisal Skills Programme checklist for qualitative research. Results were synthesised according to Noblit and Hare’s seven-step approach to meta-ethnography, which involves an iterative and inductive process of data synthesis. Results Fourteen studies were included where CGA was completed in the home, general practice, out-patient setting in acute hospitals and in hybrid models across the community and hospital-based OPD settings. Synthesis generated four key themes: (1) CGA is experienced as a holistic process, (2) The home environment enhances CGA, (3) CGA in the community is enabled by a collaborative approach to care, and (4) Divergent experiences of the meaningful involvement of older adults, caregivers and family in the CGA process. Conclusion Findings demonstrate that CGA in a home-based or OPD setting allows for a holistic and integrated approach to care for community-dwelling older adults while increasing patient satisfaction and accessibility of health=care. Healthcare professionals in the community should ensure meaningful involvement of older adults and their families or caregivers in the CGA process. Further robustly designed and well reported trials of different models of community-based CGA informed by the findings of this synthesis are warranted.

Year: 2016

description: The presented paper is written on the basis of an empirical research project focused on the use of rhetorical figures in tourism advertising slogans. The study aims to analyze the tourism advertising in Bulgarian media. The use of rhetorical figures within tourism and non-tourism advertising is investigated and comparisons are made. On that base the “rhetorical profile””of Bulgarian tourism advertising is outlined. Another important direction of the research is the analysis of slogan length – the author measured slogan length within 9 product categories and found that tourism slogans are among the longest. The paper may help future studies devoted on the relationship rhetorical figures’ usage – advertising effectiveness.

description: We consider a heteronuclear fermionic mixture on the molecular side of an interspecies Feshbach resonance and discuss atom-dimer scattering properties in uniform space and in the presence of an external confining potential, restricting the system to a quasi-2D geometry. We find that there is a peculiar atom-dimer p-wave resonance which can be tuned by changing the frequency of the confinement. Our results have implications for the ongoing experiments on Lithium-Potassium mixtures, where this mechanism allows for switching the p-wave interaction between a K atom and Li-K dimer from attractive to repulsive, and forming a weakly bound trimer with unit angular momentum. We show that such trimers are long-lived and the atom-dimer resonance does not enhance inelastic relaxation in the mixture, making it an outstanding candidate for studies of p-wave resonance effects in a many-body system.

In-depth interviews are undertaken in order to uncover manager’s perceptions of waiting. ‘The inevitability of waiting times’, ‘the negative interpretation of waiting times’ and ‘neutral waiting times’ are three themes that emerge from this qualitative study. A deeper analysis of the waiting experience may contribute to enhanced strategies for managing waiting in theme parks, improved evaluations of the service and increased customer satisfaction. Finally, some practical tips for practitioners are proposed in the form of management takeaways.

description: The nature of the gas in CO-rich debris discs remains poorly understood, as it could either be a remnant from the earlier Class II phase or of secondary origin, driven by the destruction of icy planetesimals. The aim of this paper was to elucidate the origin of the gas content in the debris discs via various simple molecules that are often detected in the less-evolved Class II discs. We present millimetre molecular line observations of nine circumstellar discs around A-type stars: four CO-rich debris discs (HD 21997, HD 121617, HD 131488, HD 131835) and five old Herbig Ae protoplanetary discs (HD 139614, HD 141569, HD 142666, HD 145718, HD 100453). The sources were observed with the Atacama Large Millimeter/submillimeter Array (ALMA) in Bands 5 and 6 with 1-2'' resolution. The Herbig Ae discs are detected in the CO isotopologues, CN, HCN, HCO$^+$, C2H, and CS lines. In contrast, only CO isotopologues are detected in the debris discs, showing a similar amount of CO to that found in the Herbig Ae protoplanetary discs. Using chemical and radiative transfer modelling, we show that the abundances of molecules other than CO in debris discs are expected to be very low. We consider multiple sets of initial elemental abundances with various degrees of H2 depletion. We find that the HCO+ lines should be the second brightest after the CO lines and that their intensities strongly depend on the overall CO/H$_2$ ratio of the gas. However, even in the ISM-like scenario, the simulated HCO+ emission remains weak as required by our non-detections.

description: The most massive halos of matter in the Universe grow via accretion and merger events throughout cosmic times. These violent processes generate shocks at many scales and induce large-scale bulk and turbulent motions. These processes inject kinetic energy at large scales, which is transported to the viscous dissipation scales, contributing to the overall heating and virialisation of the halo, and acting as a source of non-thermal pressure in the intra-cluster medium. Characterizing the physical properties of these gas motions will help us to better understand the assembly of massive halos, hence the formation and the evolution of these large-scale structures. We base this characterization on the study of the X-ray and Sunyaev-Zel'dovich effect brightness fluctuations. Our work relies on three complementary samples covering a wide range of redshifts, masses and dynamical states of clusters. We present the results of our X-ray analysis for the low redshift sample, X-COP, and a subsample of higher redshift clusters. We investigate the derived properties according to the dynamical state of our clusters, and the possibility of a self-similar behaviour based on the reconstructed gas motions power-spectra and the correlation with various morphological indicators.

description: The interplay between magnetism and metal-insulator transitions is fundamental to the rich physics of the single band fermion Hubbard model (FHM). Recent progress in experiments on trapped ultra-cold atoms have made possible the exploration of similar effects in the boson Hubbard model (BHM). This paper reports Quantum Monte Carlo (QMC) simulations of the spin-1 BHM in the ground state. In the case of antiferromagnetic interactions, which favor singlet formation within the Mott insulator lobes, we present exact numerical evidence that the superfluid-insulator phase transition is first (second) order depending on whether the Mott lobe is even (odd). In the ferromagnetic case, the transitions are all continuous. We obtain the phase diagram in the case of attractive spin interactions and demonstrate the existence of the ferromagnetic superfluid. We also compare the QMC phase diagram with a third order perturbation calculation.

Σε αντίθεση με προηγούμενες δεκαετίες που το θέμα αντιμετωπιζόταν υποκειμενικά με προσωπικές παρεμβάσεις οι οποίες στόχευαν στην ανάπτυξη κατά περίπτωση διδακτικών μοντέλων, κατά την πανδημική περίοδο Covid-19 οι εκπαιδευτικοί οργανισμοί παγκοσμίως καλούνται να αντιμετωπίσουν τα συνεχιζόμενα lockdowns εξασφαλίζοντας την απαραίτητη υλικοτεχνική υποδομή αλλά και επινοώντας διαφορετικά σενάρια διδασκαλίας, για να διασφαλίσουν την συμμετοχή και την αποτελεσματική εξ αποστάσεως εκπαίδευση μαθητών και φοιτητών και να ελαχιστοποιήσουν τους κινδύνους που συνεπάγονταν από την διακοπή της δια ζώσης λειτουργία τους. Οι στόχοι της παρούσας διπλωματικής εργασίας είναι να αποκαλυφθεί η πραγματική διάσταση της παρούσας κατάστασης με τον υβριδικό τρόπο εκπαίδευσης από την πλευρά των εκπαιδευόμενων και να προταθεί ένα μοντέλο διδασκαλίας το οποίο θα εξυπηρετεί τις ανάγκες των εκπαιδευόμενων στον μέγιστο βαθμό. Αναλυτικότερα, οι στόχοι της έρευνας είναι να αποτυπωθεί η κατάσταση της υβριδικής εκπαίδευσης πριν την πανδημική εποχή, να διερευνηθεί η εξ αποστάσεως εκπαίδευση όπως εξελίχθηκε στην πανδημική εποχή, να μελετηθούν οι μέχρι στιγμής εφαρμοσμένοι υβριδικοί τρόποι εκπαίδευσης και να προταθούν πρακτικές λύσεις για την δημιουργία ενός αποτελεσματικού μοντέλου υβριδικής εκπαίδευσης. Ο πληθυσμός-στόχος της έρευνας είναι άτομα που φοιτούν στο Τμήμα Διοίκησης Γεωργικών Επιχειρήσεων και Συστημάτων Εφοδιασμού και Διοίκησης Συστημάτων Εφοδιασμού του Γεωπονικού Πανεπιστήμιου Αθηνών. Η διερεύνηση ερευνητικών ερωτημάτων και υποθέσεων έγινε με ποσοτική και ποιοτική μεθοδολογία, η οποία ενδείκνυται για τη μελέτη στάσεων και απόψεων. Τα αποτελέσματα της έρευνας αναμένεται να χρησιμοποιηθούν από τις διοικήσεις των ανώτατων εκπαιδευτικών ιδρυμάτων και των εκπαιδευτών για την αναδιοργάνωση του υβριδικού τρόπου μάθησης.

description: Last year in [Phys. Rev. E 102, 042121 (2020)] the authors studied an overdamped dynamics of nonequilibrium noise driven Brownian particle dwelling in a spatially periodic potential and discovered a novel class of Brownian, yet non-Gaussian diffusion. The mean square displacement of the particle grows linearly with time and the probability density for the particle position is Gaussian, however, the corresponding distribution for the increments is non-Gaussian. The latter property induces the colossal enhancement of diffusion, significantly exceeding the well known effect of giant diffusion. Here we considerably extend the above predictions by investigating the influence of nonequilibrium noise amplitude statistics on the colossal Brownian, yet non-Gaussian diffusion. The tail of amplitude distribution crucially impacts both the magnitude of diffusion amplification as well as Gaussianity of the position and increments statistics. Our results carry profound consequences for diffusive behaviour in nonequilibrium settings such as living cells in which diffusion is a central transport mechanism.

description: As the insolation of an Earth-like (exo)planet with a large amount of water increases, its surface and atmospheric temperatures also increase, eventually leading to a catastrophic runaway greenhouse transition. While some studies have shown that the onset of the runaway greenhouse may be delayed due to an overshoot of the outgoing longwave radiation (OLR) -- compared to the Simpson-Nakajima threshold -- by radiatively inactive gases, there is still no consensus on whether this is occurring and why. Here, we used a suite of 1D radiative-convective models to study the runaway greenhouse transition, with particular emphasis on taking into account the radical change in the amount of water vapour (from trace gas to dominant gas). The aim of this work is twofold: first, to determine the most important physical processes and parametrisations affecting the OLR; and second, to propose reference OLR curves for N$_2$+H$_2$O atmospheres. Through multiple sensitivity tests, we list and select the main important physical processes and parametrisations that need to be accounted for in 1D radiative-convective models to compute an accurate estimate of the OLR for N$_2$+H$_2$O atmospheres. The reference OLR curve is computed with a 1D model built according to the sensitivity tests. These tests also allow us to interpret the diversity of results already published in the literature. Moreover, we provide a correlated-k table able to reproduce line-by-line calculations with high accuracy. We find that the transition between an N$_2$-dominated atmosphere and an H$_2$O-dominated atmosphere induces an overshoot of the OLR compared to the (pure H$_2$O) Simpson-Nakajima asymptotic limit. This overshoot is first due to a transition between foreign and self-broadening of the water absorption lines, and second to a transition between dry and moist adiabatic lapse rates.
The effects on residential opportunity structures on participation patterns in voluntary organizations
Creators: name: Scheu, William John
Publisher: name: University of British Columbia
Year: 2010

description: The major focus of this investigation is to explore two alternative models of individual-environment articulation for explaining individual participation in voluntary organizations. The primary question posed is whether varying voluntary organizational opportunity densities of local residential areas operate to encourage organizational participation to the same degree for all residents; or whether the density of organizational opportunity elicits differential participation depending upon an individual's personal resources, or attachments to the local residential area. The development and analysis of the problem is informed by the theory and methods of "contextual analysis." The hypotheses were tested with data from 822 respondents randomly selected from eight different "social areas" in Metropolitan Vancouver. The areas were purposively chosen from a stratified typology—similar in nature to Wendall Bell's Social Area Typology. In general, the analysis suggests that the opportunity densities of a residential areas do not act independently of, but in combination with different individual characteristics to produce differences in organizational participation of urban residents. Increased organizational opportunities present in the immediate residential environment only conditionally affect an increase in organizational memberships for the better educated or the more wealthy.

description: Edge computing provides an agile data processing platform for latency-sensitive and communication-intensive applications through a decentralized cloud and geographically distributed edge nodes. Gaining centralized control over the edge nodes can be challenging due to security issues and threats. Among several security issues, data integrity attacks can lead to inconsistent data and intrude edge data analytics. Further intensification of the attack makes it challenging to mitigate and identify the root cause. Therefore, this paper proposes a new concept of data quarantine model to mitigate data integrity attacks by quarantining intruders. The efficient security solutions in cloud, ad-hoc networks, and computer systems using quarantine have motivated adopting it in edge computing. The data acquisition edge nodes identify the intruders and quarantine all the suspected devices through dimensionality reduction. During quarantine, the proposed concept builds the reputation scores to determine the falsely identified legitimate devices and sanitize their affected data to regain data integrity. As a preliminary investigation, this work identifies an appropriate machine learning method, Linear Discriminant Analysis (LDA), for dimensionality reduction. The LDA results in 72.83% quarantine accuracy and 0.9 seconds training time, which is efficient than other state-of-the-art methods. In future, this would be implemented and validated with ground truth data.

description: In this study, Call Detail Records (CDRs), covering Budapest, for the month of June in 2016 has been analyzed. During this observation period, the 2016 UEFA European Football Championship took place, which affected significantly the habit of the residents, despite the fact that not a single match was played in the city. We evaluated the fans' behavior in Budapest, during and after the Hungarian matches, and found that the mobile phone network activity reflects the football fans' behavior, demonstrating the potential of mobile phone network data within a social sensing system. The Call Detail Records are enriched with mobile phone properties to analyze the subscribers' devices. Applying the device information (Type Allocation Code) from the activity records, the Subscriber Identity Modules, that do not operate in cell phones are omitted from mobility analyses, allowing to focus on people. The mobile phone price is proposed and evaluated as a socioeconomic indicator, and correlation between the phone price and the mobility customs have been found. We also found that, beside the cell phone price, the subscriber age and the subscription type also have an effect on the mobility. On the other hand, these do not seem to affect the interest in football.

Determination of spin chirality using x-ray magnetic circular dichroism

description: A 3-fold symmetric kagome lattice that has negative spin chirality can give a non-zero x-ray magnetic circular dichroism (XMCD) signal, despite that the total spin moment amounts to zero. This is explained by a hitherto unnoticed rule for the rotational symmetry invariance of the XMCD signal. A necessary condition is the existence of an anisotropic XMCD signal for the local magnetic atom, which can arise from a spin anisotropy either in the ground state or the final state. The angular dependence of the XMCD as a function of the beam direction has an unusual behavior. The maximum dichroism is not aligned along the spin direction, but depends on the relative orientation of the spin with respect to the atomic orientation. Therefore, different geometries can result in the same angular dependence, and the spin direction can only be determined if the atomic orientation is known. The consequences for the x-ray magneto-optical sum rules are given. The integrated XMCD signals are proportional to the anisotropy in the orbital moment and the magnetic dipole term, where the isotropic spin moment drops out.

description: Under the hypotheses of smoothness of the interactions in the coupling constant, locality, Poincare invariance, Lorentz covariance, and the preservation of the number of derivatives on each field in the Lagrangian of the interacting theory (the same number of derivatives like in the free Lagrangian), we prove that in D=11 there are no cross-interactions between the graviton and the massless gravitino and also no self-interactions in the Rarita-Schwinger sector. A comparison with the case D=4 is briefly discussed.

description: We present a measurement of the B0 --> Lambda-bar p pi- branching fraction performed using the BaBar detector at the PEP-II asymmetric e+e- collider. Based on a sample of 467 million BB-bar pairs we measure B(B0 --> Lambda-bar p pi-) = [3.07 pm 0.31 (stat.) pm 0.23 (syst.)] x 10^{-6}. The measured differential spectrum as a function of the dibaryon invariant mass m(Lambda p) shows a near-threshold enhancement similar to that observed in other baryonic B decays. We study the Lambda-bar polarization as a function of Lambda-bar energy in the B0 rest frame (E*_Lambda) and compare it with theoretical expectations of fully longitudinally right-polarized Lambda-bar at large E*_Lambda.

description: Incentive programs are a common tool used by businesses and other organizations to encourage specific behavior in customers and employees. This research note provides detailed information on how incentive programs may be an effective tool for encouraging sustainable travel-related purchases. A discussion outlining the existing research on green consumerism and consumer-driven solutions for encouraging sustainability is followed by industry and academic information on incentive programs. A focus group study then builds on this existing knowledge by looking at young professionals from Raleigh and Greenville, North Carolina to determine the effectiveness of incentive programs at encouraging green consumerism while traveling. Analysis of the resulting dialogue confirmed incentive programs may be an effective tool for encouraging sustainable travelrelated purchases. Based on this result, recommendations provide design and logistical considerations that are important to take into account when trying to create an effective incentive program for sustainable tourism marketed to young professionals.
