Tourism as industry and field of study

Purpose: The purpose of this article is (1) to highlight the dual, Janis-faced, nature of the study of tourism as an industry and as a field of study; (2) to discuss how education is used to promote sustainable tourism and prevent overtourism, both in the academic arena as well as where tourism occurs; and (3) to offer suggestions concerning the value of education as an avenue for harmonizing the Janus-faced character of tourism, in order to foster a tourism industry that can better achieve global sustainability. Design/methodology/approach: This paper combines literature review with assessment. The authors use existing literature on overtourism, tourism education, and critical tourism studies to provide insights into how education can help enhance sustainable tourism practices. Findings: The authors find that there are two “faces” of tourism education, one focusing on growth and capital accumulation, and the other on the critical analysis of tourism, highlighting problems with the industry. The authors propose that this Janus-faced approach to tourism education should be reconciled to enable the promotion of sustainability in the industry and in tourist destinations. Practical implications: This chapter outlines an educational path for tourism and hospitality programs, as well as for local publics, to foster more sustainable forms of tourism and avoid overtourism. Unsustainable tourism, however, is a global problem that requires a concerted international solution. Originality and value: The authors apply the concept of Janus-faced tourism to better understand the divergence between theoretically oriented tourism education in the academy and practically oriented tourism education in management and hospitality schools. This analysis offers suggested paths towards transforming education in both hospitality schools and in local destinations to foster scale-appropriate forms of sustainable tourism.
Surface Plasmon Resonance-Based Temperature Sensor with Outer Surface Metal Coating on Multi-Core Photonic Crystal Fibre

We report an innovative design of a multi-core photonic crystal fibre-based surface plasmon resonance temperature sensor using ethanol and benzene as temperature-sensitive materials with a segmented outer-surface metal coating scheme. A stable sensing performance for a detection range of 10–80 ∘ C was found while using ethanol as the temperature-sensitive material; while using benzene both blue and red frequency shifts were observed. The maximum temperature sensitivities obtained from this proposed temperature sensor were 360 pm/ ∘ C and 23.3 nm/ ∘ C with resolutions of 2.78 × 10 − 1 ∘ C and 4.29 × 10 − 3 ∘ C, respectively, when using ethanol or benzene as the sensing medium.
Survey on Face Recognition using Neural Network

: The strategy of face recognition involves the examination of facial features in a picture, recognizing those features and matching them to 1 of the many faces in the database. Now a day face recognition continuous in demand in image processing system because of its requirements such as authentication access control, surveillance systems. Face can be categorize into two process such as appearance and features. The proposed system of face recognition and extraction is done based on the neural network.
Lowest observed surface and weld losses in fused silica fibres for gravitational wave detectors

High purity fused silica has become the cornerstone choice for use in the final monolithic stage of the mirror suspensions in the gravitational wave observatories Advanced LIGO (aLIGO) and Advanced Virgo (AdV). The ultra-low thermal noise contributed by these suspensions is one of the key improvements that permitted the Nobel prize winning first direct measurement of gravitational waves in 2015. This paper outlines the first in situ study undertaken to analyse the thermal noise of the final monolithic stage of the aLIGO Hanford detector mirror suspensions. We analysed short operational periods of this detector, when high excitation of the transverse ‘violin’ modes of the silica suspension fibres occurred. This allowed detailed measurements of the Q-factor of violin modes up to order 8 of individual fibres on separate masses. We demonstrate the highest silica fibre violin mode Q-factors yet measured of up to 2 × 109. From finite element modelling, the dominant surface and weld losses have been calculated to be a factor of 3 to 4 better than previously accepted, and as a result, we demonstrate that the level of noise in the aLIGO final stage silica suspensions is around 30%–40% better than previously estimated between frequencies of 10–500 Hz. This leads to an increase in the estimated event rate by a factor of 2 for aLIGO, if suspension thermal noise became the main limitation to the sensitivity of the detector.

Zebra rock and other Ediacaran paleosols from Western Australia

Abstract Zebra rock is an ornamental stone from the early Ediacaran, Ranford Formation, around and in Lake Argyle, south of Kununurra, Western Australia. It has been regarded as a marine clay, liquid crystal, groundwater alteration, unconformity paleosol or product of acid sulfate weathering. This study supports the latter hypothesis and finds modern analogues for its distinctive red banding in mottling of gleyed soils. Other acid sulfate paleosols of desert playas (Gypsids) are also are found in the Ranford Formation, as well as calcareous desert paleosols (Calcids). The megafossil Palaeopaschnicnus also found in associated grey shales may have been a chambered protozoan, but Yangtziramulus in calcic paleosols is most like a microbial earth lichen. Soil climofunctions are evidence of an arid, cool temperate climate during the early Ediacaran. KEY POINTS Ornamental stones known as ‘zebra rock’ are interpreted as Ediacaran gleyed soils. Gypsum desert-rose beds are interpreted as Ediacaran acid sulfate soils (Gypsids). Calcareous nodular loess beds are interpreted as Ediacaran desert soils (Gypsids).
Real time emulator for parallel connected dual-PMSM sensorless control

This paper presents a real-time emulator of a dual permanent magnet synchronous motor (PMSM) drive implemented on a field-programmable gate array (FPGA) board for supervision and observation purposes. In order to increase the reliability of the drive, a sensorless speed control method is proposed. This method allows replacing the physical sensor while guaranteeing a satisfactory operation even in faulty conditions. The novelty of the proposed approach consists of an FPGA implementation of an emulator to control the actual system. Hence, this emulator operates in real-time with actual system control in healthy or faulty mode. It gives an observation of the speed rotation in case of fault for the sake of continuity of service. The observation of the rotor position and the speed are achieved using the dSPACE DS52030D digital platform with a digital signal processor (DSP) associated with a Xilinx FPGA.
Tolerance to PVY infection in potato is conditioned by perturbation of small RNA– gibberellin regulatory network

Potato virus Y (PVY) is the most economically important potato viral pathogen worldwide. We aimed at unraveling the roles of small RNAs (sRNAs) in the complex immune signaling network controlling the establishment of tolerant response of potato cv. Désirée to the virus. We identified and quantified the endogenous miRNAs and phasiRNAs as well as virus-derived sRNAs. We constructed a sRNA regulatory network connecting sRNAs and their targets identified to link sRNA level responses to physiological processes. We discovered an interesting novel sRNAs – gibberellin (GA) regulatory circuit being activated as early as 3 days post inoculation, before viral multiplication can be detected. Increased levels of miR167 and phasiRNA931 were reflected in decreased levels of transcripts involved in GA biosynthesis. Moreover, decreased concentration of GA confirmed this regulation. We have additionally showed that this regulation is salicylic acid dependent as the response of sRNA network was attenuated in salicylic acid-depleted transgenic counterpart NahG-Désirée expressing severe disease symptoms. Moreover, we found that differentially expressed miR6022, which targets leucine-rich-repeat receptor-like kinases, likely links GA signaling with immune responses. Besides downregulation of GA signaling, regulation of several other parts of sRNA network in tolerant Désirée revealed striking similarities to responses observed in mutualistic symbiotic interactions. The intertwining of different regulatory networks revealed here shows how developmental signaling, symptomology and stress signaling are balanced.
White Adipose Tissue Undergoes ‘browning’ in Tree Shrews (Tupaia belangeri) During Cold Acclimation

Abstract. Cold induces a transformation of adipocytes in white adipose tissue (WAT) into ‘beige’ adipocytes with a brown adipose-like phenotype in a process known as ‘browning’. In the present study, cold acclimation was characterized over 49 days of exposure to 5°C (with controls housed at 25°C) in Tupaia belangeri using physiological indices, positron emission tomography-computed tomography (PET/CT) scan, adipose tissue morphology study, and flow cytometry. The results showed that during cold acclimation, body mass and WAT mass and content increased significantly, and there were significant effects of cold exposure on the mean standardized uptake values (SUV) for inguinal, omental, and mesenteric WAT. Adipose tissue morphology showed that the abdominal omental WAT had taken on characteristics of beige adipocytes, including smaller lipid droplets, and expression of uncoupling protein 1 (UCP1). Flow cytometric analysis showed that a new cell population had appeared in WAT by day 49. In the R1 (original) and R2 (new) groups of cells, 69.6% and 95.3% of the cells were positive for UCP1, respectively. All of these results indicate that cold exposure induced WAT browning, which would increase thermogenic properties in T. belangeri under cold acclimation.
Effects of plant quality and ant defence on herbivory rates in a neotropical ant‐plant

1. Understanding the degree to which populations and communities are limited by both bottom‐up and top‐down effects is still a major challenge for ecologists, and manipulation of plant quality, for example, can alter herbivory rates in plants. In addition, biotic defence by ants can directly influence the populations of herbivores, as demonstrated by increased rates of herbivory or increased herbivore density after ant exclusion. The aim of this study was to evaluate bottom‐up and top‐down effects on herbivory rates in a mutualistic ant‐plant.
Performance testing of STL and Qt library elements in multi-threaded processing

In recent years multithreaded processing has become a important programming aspect. Computers with a multi-core processor are now widely available, enabling the creation of more efficient applications. Many libraries support multithreaded solutions, but performance information is often lacking. The use of appropriate data structures and algorithms significantly speeds up the process of creation and development of applications. Article describes selected elements of the Qt and STL library and compares their performance in concurrent programming. The test was performed with custom applications created with C++. The time needed to perform individual operations was analysed.
Toward a Science of Effective Cognitive Training

A long-standing question in the behavioral sciences is whether cognitive functions can be improved through dedicated training. It is uncontested that training programs can lead to near transfer, meaning increased performance on untrained tasks involving similar cognitive functions. However, whether training also leads to far transfer, meaning increased performance on loosely related untrained tasks or even activities of daily living, is still hotly debated. Here, we review the extant literature and, in particular, the most recent meta-analytic evidence and argue that the ongoing crisis in the field of cognitive-training research may benefit from taking a more mechanistic approach to studying the effectiveness of training. We propose that (a) adopting a more rigorous theoretical framework that builds on a process-based account of training and transfer, (b) considering the role of individual differences in the responsiveness to training, and (c) drawing on Bayesian models of development may help to solve controversial issues in the field and lead the way to designing and implementing more effective training protocols.
A Low-Voltage Split Memory Architecture for Binary Neural Networks

This paper performs an in-depth study of error-resiliency of Neural Networks(NNs). Our investigation has resulted into two important findings. First, we found that Binary Neural Networks (BNNs) are more error-tolerant than 32-bits NNs. Second, in BNNs the network accuracy is more sensitive to errors in Batch Normalization Parameters(BNPs) than that in binary weights. A detailed discussion on the same is presented in the paper. Based on these findings, we propose a split memory architecture for low power BNNs, suitable for IoTs. In the proposed split memory architecture, weights are stored in area-efficient 6T SRAM, and BNPs are stored in robust 12T SRAM. The proposed split memory architecture for BNNs synthesized in UMC 28nm is highly energy efficient as the Vmin (minimum operating voltage) can be reduced to 0.36 V, 0.52 V, and 0.52 V for the MNIST, CIFAR10, and ImageNet datasets respectively, with accuracy drop of less than 1%.

This review examines some of the recent proposals for various routes of application of Insulin delivery system along with the particular attention to its latest intervention of novel drug delivery system.
Explicit Content

This chapter investigates the transformation of traditional face-to-face sexual harassment (SH) to online sexual harassment (OSH). First, an overview of traditional workplace sexual harassment is discussed. Next, the issues of cyberbullying and cyberstalking are presented as a bridge to online sexual harassment, as the two former types of behavior can be seen in online sexual harassment and have both received considerable attention. Then, current research concerning online sexual harassment will be presented, including a discussion of factors that facilitate OSH, social media as a site of harassment, coping strategies, and effects. This concept is worthy of study because online sexual harassment represents a way for the perpetrator to victimize his or her target without the boundaries and restrictions of time, location, or fear of consequence. This chapter concludes with some practical recommendations for organizational leaders to implement to prevent both on- and offline SH from occurring within their company.
Identification des gènes impliqués dans la production et la détoxication des espèces activées de l'oxygène chez Hevea brasiliensis et leur caractérisation dans le latex

Hevea brasiliensis, un arbre tropical, est la source principale de caoutchouc naturel commercialement viable. La biosynthese de caoutchouc se passe dans les cellules specialisees appelees laticiferes. Il represente jusqu’a 90% de la matiere seche du latex. Le latex, laiteux, s’ecoule de l’encoche faite sur l’ecorce de l’arbre jusqu’aux cellules laticiferes. La collecte de latex, faite par saignee reguliere tous 2-3 jours, est vraiment stressante pour l’arbre. Pour stimuler la production de latex, un generateur d’ethylene peut etre applique sur le panneau de saignee. Le stress s’intensifie avec l’application hormonale. La production d’especes activees de l’oxygene (ROS) se fait en reponse aux stress environnementaux ainsi que lors de l’exploitation de l’arbre. Au-dela d’un certain seuil, la production de ROS est massive dans les laticiferes. De nombreuses etudes ont montre que les ROS entraine une degradation par peroxydation des lipides insatures des membranes et ensuite une destabilisation et lyse des organites. La lyse des lutoides permet la liberation des facteurs de coagulation dans le latex entrainant la coagulation in situ des particules de caoutchouc dans l’ecorce des arbres stresses. Ce syndrome physiologique, appele syndrome de l’encoche seche (TPD), est un des facteurs limitant la production de caoutchouc.Ce travail de these vise a identifier les genes associes a la production et la neutralisation des ROS ainsi que leurs caracterisations dans les laticiferes. Premierement, nous avons fait une analyse bibliographique complete sur les genes associes a la production et la neutralisation des ROS chez l’hevea et les plantes modeles. La NADPH oxydase a ete decrite comme la source principale de ROS chez les arbres stresses. Les enzymes antioxydantes et les antioxydants constituent le systeme de neutralisation des ROS. Deuxiemement, a partir d’une analyse a l’echelle du genome, 407 genes impliques dans la production des ROS et dans leur neutralisation ont ete identifies. Troisiemement, a partir d’une analyse du transcriptome, 164 genes redox ont ete detectes dans le latex du clone SP 217 et 161 dans celui du clone PB 260. Quatriemement, a partir des petits ARNs et d’une analyse degradome, 13 genes ont ete identifies pour etre clives par 11 microARNs et 15 genes clives par 16 petits ARNs phases dans le latex. Enfin, cette etude a mis en evidence des regulations specifiques de la production des ROS et du systeme antioxydant dans le latex. HbRBOH2 a ete identifie comme la source principale de ROS dans le latex. HbCuZnSOD4 pourrait etre le contributeur majeur de la neutralisation des ROS dans le latex des arbres atteints de TPD.
¿Quiénes cambiaron de partido durante la Gran Recesión? Un estudio de 12 países de Europa occidental

Electoral volatility levels after the Great Recession of 2008 were record high in most Western European countries. Among the main causes of this electoral instability are the negative development of the economy, the crisis of the traditional parties and the change in the issues of political competition. At the individual level, it is unknown what factors caused voters to change their party preference after the Great Recession. Furthermore, in general, little is known about the differences between a stable and volatile voter. This study of 12 Western European countries after the economic crisis concludes that the economic voter model did not always explain the change in party preference after 2008, while sentiments of political dissatisfaction would help us to understand the change of parties between elections.
BassNet: A Variational Gated Autoencoder for Conditional Generation of Bass Guitar Tracks with Learned Interactive Control

Deep learning has given AI-based methods for music creation a boost by over the past years. An important challenge in this field is to balance user control and autonomy in music generation systems. In this work, we present BassNet, a deep learning model for generating bass guitar tracks based on musical source material. An innovative aspect of our work is that the model is trained to learn a temporally stable two-dimensional latent space variable that offers interactive user control. We empirically show that the model can disentangle bass patterns that require sensitivity to harmony, instrument timbre, and rhythm. An ablation study reveals that this capability is because of the temporal stability constraint on latent space trajectories during training. We also demonstrate that models that are trained on pop/rock music learn a latent space that offers control over the diatonic characteristics of the output, among other things. Lastly, we present and discuss generated bass tracks for three different music fragments. The work that is presented here is a step toward the integration of AI-based technology in the workflow of musical content creators.
THE DYNAMICS OF A COLONIZING POPULATION OF POA ANNUA

This paper describes a demographic analysis of a colonizing population of Poa annua. The population was characterized by a burst of growth growing the first autumn of colonization, after which there was little further change, apart from small seasonal oscillations. Recruitment of seedlings also increased towards a ceiling during the first autumn, after which it showed marked seasonal oscillation, with peaks in spring and autumn. During colonization there was an increase in numbers of old individuals in the population, and the age structure developed a wake—like pattern, corresponding to the seasonal peaks and troughs of recruitment. Reproduction decreased as population density increased and was much influenced by season, tending to be greatest in the summer. Mortality increased with population density and was also influenced by season, tending to be greater in the autumn. Overall, the analysis draws attention to the interdependence of the spatial and temporal dimensions in plant populations. See full-text.
