On-site corrosion monitoring experience in concrete structures: potential improvements on the current-controlled polarization resistance method
Authors: Ramón J. E. , Castillo Á. , Martínez I.
Published: October 2021

The need for proactive maintenance of reinforced concrete structures with non-destructive testing (NDT) is less disputable today than ever. One of the most promising strategies in this regard is the in-situ measurement of the reinforcement corrosion rate. This study explored the reliability of modulated current confinement method (hereafter MCC) based on a review of in-situ measurements made with that technique in real-life structures over a 13-year period. The most prominent problems detected included defective confinement of the polarization current in low-resistivity environments and over-polarization of passive reinforcement. The findings, which showed enhancement of MCC reliability to depend on improving the electrochemical current regulation and control methodologies presently in place, are being applied to improve the design of the next generation of corrosion meters.

Empirical Analysis on Effectiveness and Long-Acting Mechanism of Regional Physical Education Teaching
Authors: Zheng Hui
Published: October 2021

The physical quality of students is an important goal of quality education, and the basis for the training of high-quality talents. Physical education (PE) is of great significance to enhance students’ physical fitness, and improve their awareness of lifelong physical exercise. Targeting several colleges in Guizhou Province, this paper empirically studies the effectiveness and long-acting mechanism of regional PE teaching through interview, questionnaire survey, and mathematical statistics. Firstly, the status quo of PE teaching in the colleges was surveyed. The survey results show the following problems in college PE teaching: the lack of systematic organization and management, the outdated and non-diverse forms of activities, the absence of a strong sports atmosphere, and the lack of interest among the students. To solve these problems, this paper constructs a long-acting mechanism for regional PE teaching, and verifies its implementation effect through an empirical study. The mechanism was found to enhance the students’ physical fitness, help them develop a good habit of physical exercise, and boost their awareness of lifelong physical exercise. This research greatly promotes the lifelong physical exercise of college students and the PE teaching quality in colleges and universities.
Les pèlerinages de l’Afrique francophone subsaharienne en Terre Sainte : la formation discursive d’une communauté de croyants
Authors: Sela Tal
Published: October 2021

Cet article porte sur un phénomène culturel peu connu des chercheurs qui s’intéressent au tourisme religieux en Terre Sainte : les pèlerinages effectués à partir de l’Afrique francophone subsaharienne. Cette étude du voyage de pélerinage met en évidence sa dimension groupale, facteur crucial de l’expérience religieuse individuelle. À l’aide des outils de l’analyse du discours, de l’argumentation dans le discours et de la sémiotique de l’image, cette enquête dévoile différentes formes d’identité collective qui se construisent dans le discours du tourisme tel qu’il se développe dans l’univers francophone africain. Une forme particulière d’identité « nationale » est forgée dans le discours que Jürgen Bühler, le président de l’Ambassade Chrétienne internationale de Jérusalem, adresse aux téléspectateurs africains de la chaîne de télévision évangéliste (LMTV) depuis ses studios en Côte d’Ivoire ; une identité groupale fondée sur les valeurs sociales de l’amitié émerge dans les affiches publicitaires que l’agence de voyage Gota distribue dans les communautés chrétiennes béninoises ; enfin, la formation d’un groupe d’élite se constitue à partir de la valeur symbolique des objets matériels – attestations et décorations – que les pèlerins accumulent durant et après le voyage. Cette analyse des discours et représentations du pèlerinage en Terre Sainte met en évidence sa dimension sociale : il apparaît qu’il va bien au-delà de l’expérience spirituelle du croyant isolé à la recherche de Dieu.
Tourisme radiophonique et imaginaires touristiques : quand les sons rendent sensibles les lieux, les pratiques et les acteurs
Authors: Hutin Séverine Equoy
Published: October 2021

Cette contribution propose de conduire une analyse sémio-discursive argumentative du magazine de tourisme radiophonique Et si on partait ? diffusé sur la station de grande écoute Europe1 durant l’été 2020. Elle met au jour les procédés et les mécanismes discursifs qui « font tourisme » et rendent les territoires, les pratiques et les acteurs sensibles à l’auditeur. Il ne s’agit pas ici de considérer la radio comme un média « privé d’image » mais bien de prendre en compte sa médiativité et les spécificités de l’espace sonore pour analyser les productions radiophoniques dédiées au tourisme et les imaginaires touristiques qu’elles véhiculent et construisent.
L’analphabétisme au sein d’une communauté linguistique minoritaire : la construction du sujet en problème social (1984-1998)
Authors: Arrighi Laurence
Published: October 2021

Quinze ans de discours médiatiques (1984-1999) portant sur l’analphabétisme au sein de la communauté linguistique acadienne (Canada) permettent d’illustrer comment un thème devient un problème social. L’étude s’arrête sur l’émergence du discours qui construit l’analphabétisme comme un problème public et suit l’évolution du discours sur le sujet. À la suite de Felstiner, Abel et Sarat (1980) mais aussi de Cefaï (1996), l’article montre que le curriculum de la construction d’un problème public se présente en différentes phases au sein desquelles la dramatisation du sujet s’accomplit par des biais notamment rhétoriques.
La dissonance dans le dissensus : manifestations et conséquences argumentatives d’une attaque psychologisante
Authors: Pison Leslie
Published: October 2021

L’objectif de cet article est de décrire le fonctionnement argumentatif de l’expression « dissonance cognitive » sur le réseau social Twitter. La démarche descriptive proposée s’attache à rendre compte de l’usage de ce lexème dans le cadre d’échanges polémiques. La spécificité de l’expression « dissonance cognitive », contrairement à d’autres attaques psychiatrisantes, réside dans le fait qu’elle est également une critique méta-argumentative. En effet, « dissonance cognitive » désigne initialement en sciences cognitives une incohérence entre deux éléments perçus par le cerveau. Les analyses menées dans cet article, en portant notamment une attention particulière au contre-discours, montrent que cette théorisation est réinvestie lors de l’usage argumentatif de « dissonance cognitive », qui produit un double mouvement de réfutation-disqualification. L’argument de la dissonance cognitive est par conséquent assimilable à un ad hominem tu quoque.
Les aménagements hydrauliques et la gestion de l’eau avant la période romaine sur le territoire de l’actuelle Albanie
Authors: Jaupaj Lavdosh
Published: October 2021

Liés au phénomène d’urbanisation, les aménagements hydrauliques dans les cités illyriennes de l’intérieur des terres montrent d’étroites ressemblances avec ce que l’on trouve dans les cités coloniales de la côte ionio-adriatique, ce qui s’explique par la continuité et sans doute l’intensification des contacts entre les deux régions et les deux cultures. On peut le voir notamment avec les citernes du koinon de Byllis, qui présentent de grandes affinités avec celles d’Apollonia. En l’absence de sources littéraires et épigraphiques spécifiques, seuls les vestiges archéologiques fournissent des informations sur la manière dont ces cités ont pu gérer les problèmes de l’eau. Les aménagements hydrauliques sont liés au développement urbain et répondent au schéma méditerranéen, dans lequel se posent les problèmes du stockage de l’eau, plus rare en saison sèche, et de l’évacuation rapide des eaux violentes résultant des orages, notamment pour les habitats aménagés sur des sites en pente.
L’acqua di Mozia: captazione, consumo e significati in ambito civile e religioso
Authors: Nigro Lorenzo
Published: October 2021

L’eau est une ressource de base sur l’île de Motyè. Un aquifère phréatique jaillit du banc argilo-calcaire du secteur méridional de l’île sicilienne alimentant ainsi l’environnement du lagon, ce qui rendit possible l’occupation humaine depuis la Préhistoire et attira les Phéniciens durant leur expansion à travers la Méditerranée. La zone des sources sur le rivage sud fut la première occupée par les nouveaux-venus d’Orient: ils y fondèrent une place sacrée près de la principale source d’eau et de son étang. Dès lors et pendant quatre siècles au moins, la ville portuaire bénéficia d’une abondance d’eau fournie par des puits et conservée dans des citernes. Les fouilles récentes de l’Université de Rome La Sapienza ont fourni de nouvelles données sur les installations hydrauliques de Motyè. Le bassin connu comme ‘kothon’ a été identifié de manière définitive comme une piscine sacrée tandis que puits, canalisations et citernes ont été découverts dans les quartiers d’habitation et les bâtiments publics et religieux.
L’apparition et la diffusion des citernes en Méditerranée phénico-punique
Authors: Fumadó Ortega Iván
Published: October 2021

L’article présente un bilan historiographique préliminaire des citernes identifiées sur des sites phénico-puniques. L’auteur a collecté les données relatives à la morphologie, la chronologie, la technologie et le contexte architectural de ces citernes. Cet inventaire lui a permis de réaliser des observations sur les phénomènes suivants : l’apparition relativement tardive des citernes dans les sites de la diaspora phénicienne (à partir de la fin du VIe siècle av. J.-C.), la large diffusion de la forme « a bagnarola », le développement des réservoirs à partir du IIIe siècle av. J.-C. et la dynamique inégale et plus tardive de leur utilisation dans la péninsule Ibérique. Ce bilan entend présenter la diffusion des citernes sur les sites phénico-puniques, aussi bien au Levant qu’en Méditerranée. Ces citernes ont été parfois décrites avec soin mais, souvent, insuffisamment contextualisées. Ce bilan devrait faciliter le dialogue entre les spécialistes des mondes phénico-punique et gréco-romain.
Pozzolans in Mortar in the Roman Empire: An Overview and Thoughts on Future Work
Authors: Lancaster Lynne C.
Published: October 2021

This paper focuses on three different ingredients used to create hydraulic mortar: volcanic ash, crushed terracotta, and plant ash. Each one imparts somewhat different characteristics to the mortar and has a different processing method, which would have affected the chaîne opératoire of the building site. One goal is to examine these characteristics and processes. A second goal is to examine some problems in the terminology used to identify the ingredients. How can choices in terminology, such as “crushed tile mortar” vs. “crushed terracotta mortar” or “mortar with charcoal” vs. “mortar with ash”, affect our understanding of the significance of choices made by ancient builder? I argue that using precise and objective terms to describe the ingredients in the mortar is an important step in being able to determine source materials, which in turn can provide insight into organizational practices on the worksite.
Pre-Roman waterproofing mortars in Ancient Corinth: materials and technology
Authors: Siddall Ruth
Published: October 2021

This paper will present both petrographic and preliminary chemical analyses which indicate that waterproofing mortars in the Fountains of Peirene and Glauke, at the Asklepieion and its associated springs and at the springhouse of Upper Peirene on the Acrocorinth had hydraulic properties which were previously unrecognised in Pre-Roman cements in this region. The waterproofing mortars of pre-Roman Corinth demonstrate a high degree of technical understanding of the production of lime-silica cements, which has otherwise been previously overlooked.
Des mortiers hydrauliques dans la ville grecque de Marseille ? ive siècle av. J.-C. – 50 av. J.-C.
Authors: D’Ovidio Anne-Marie , Bromblet Philippe
Published: October 2021

À Marseille, les premiers mortiers rosâtres de sols, murs et de structures hydrauliques à base de chaux et poussière de tuileau ont été découverts dans un remblai daté du ve s. av. J.-C. et en place dans la première moitié du ive s. av. J.-C. Cet article montre dans une première partie l’expansion urbaine de ces mortiers avec une accélération à l’époque augustéenne. La seconde partie aborde la question du mode de prise de ces mortiers hydrauliques à travers la recherche des réactions pouzzolaniques entre le liant à base de chaux et l’agrégat de tuileau. La détermination et la quantification de l’hydraulicité du liant utilisé et de la pouzzolanicité des tuileaux sont difficiles avec les méthodes d’analyse courantes comme la DRX ou le MEB/EDS que nous employons. Dans quelques cas favorables, la présence de grumeaux de chaux, l’existence d’une couronne de réaction visible autour des grains de tuileau ou encore l’observation de grains silicatés anhydres permettent néanmoins de préciser la nature du liant et de confirmer la réalité d’une réaction pouzzolanique que l’on ne fait que supposer le plus souvent.
Rivestire e proteggere le pareti degli edifici in epoca romana
Authors: Mimmo Milena , Carrive Mathilde
Published: October 2021

Le présent article s’intéresse aux revêtements pariétaux en béton de tuileau des entrepôts de Rome, d’Ostie et de Portus, dont nous avons analysé les caractéristiques macroscopiques des composants et les modalités de mise en œuvre. L’objectif était de comprendre les motivations qui ont conduit au choix de ce type de revêtement. Il est appliqué dans des zones, des édifices et des espaces sujets à l’humidité, afin de garantir des conditions micro-climatiques favorables à la conservation des marchandises. Ces revêtements semblent également avoir servi à protéger les parois de l’usure mécanique causée par le passage d’hommes chargés de marchandises et des dommages provoqués par les apports d’eau nécessaires à l’entretien de ces espaces. L’emploi de ces revêtements apparaît déterminé par des exigences contextuelles précises mais également par la fonction des différents espaces (circulation, distribution, stockage, représentation). Ces revêtements peuvent être considérés, avec prudence, comme des indices pour déterminer les activités menées dans les différentes parties des entrepôts.
The Prospect from the Watershed: Places and Poetics, Figures and Narratives
Authors: Robinson Betsey A.
Published: October 2021

This paper takes a broad view of the rivers and springs that watered the lands around the Corinthian Gulf and ultimately flowed into it. Gulf shores were inhabited by Achaians, Corinthians, Boiotians, Phokians, Lokrians, and Aitolians, different ethnic groups with diverse interests and influences but united by intervisibility and direct communication along and across the Gulf. While some springs in this watershed—for instance, Peirene, Hippokrene, and Kastalia—became famous, the reputations of the rivers were quite restricted. None is navigable, and few flow through the dry season, but namesakes elsewhere in the Greek world reflect territorial and historical claims and reify ethnic and political relationships. Sources anchored communities and supported agriculture. Rivers and valleys defined territories, and offered routes into the interior. Water-bodies were named, integrated into genealogies, and became actors in mythical narratives. Literature and archaeology reveal evidence for the use of water in ritual at some sites, and sometimes specifically in the worship of water-deities. The Corinthian Gulf watershed thus offers a microcosm of watery phenomena in the ancient world.
Water, Myth, and Cult in Nemea
Authors: Barfoed Signe
Published: October 2021

This article reviews the water supply to the Sanctuary of Zeus in Nemea in the Archaic period and considers the importance of water in the site’s history and sacred rituals. The so-called Rawson Deposit, a votive deposit excavated outside the Sanctuary of Zeus in Ancient Nemea preserves the remains of a small shrine, likely associated with a nearby spring. It has been suggested that the recipients of the cult were Demeter and Kore, and other deities are also possible, but the nature of the deposit suggests that the nymph of the source was worshipped there. The cult connected to the spring shrine, and the myths and literary sources connected to Nemea provide further insight to the importance of water supply and the diversity of ritual practices in the area in the formative period of the Sanctuary of Zeus in Nemea.
Offerings, Ritual, and Water: The Case of the Sacred Spring at Corinth
Authors: Kopestonsky Theodora B.
Published: October 2021

Corinth, a polis known for being “well-watered” in antiquity according to Simonides, encompasses several springs associated with ritual activity from the Archaic to Hellenistic periods. While the Peirene Fountain may be the most well-known fountain, the Sacred Spring is the most significant example of a water-related cult site in Corinth. Located in the Upper Lechaion Road valley, the Sacred Spring began as a natural source, which was improved from the 8th century BCE, its area developing into a sanctuary that likely continued in use until 146 BCE. Its position in the heart of the polis suggests that it may have had an important civic as well as religious role. The small finds, which include articulated female figurines, standing and seated female figurines, loomweights, jewelry, animal figurines, and a few bronze arrowheads, have not been systematically studied until now. This paper provides a preliminary analysis of the small finds, especially the terracotta figurines, in order to establish dedicatory tendencies and possible rites. When compared to similar assemblages and water-related cult sites, objects from the area of the Sacred Spring indicate that the source sanctuary was especially important to women and may suggest that transitional rituals, possibly female maturation rites, were conducted there.
Eaux et cultes en Phénicie à l’époque perse
Authors: Garbati Giuseppe , Pedrazzi Tatiana
Published: October 2021

The cultic use of water in Phoenicia is well documented, especially from the Persian age. It is particularly evident, for instance, in the celebrated extra-urban sanctuaries of Amrit, in Syria, and Bostan esh-Sheikh, in Lebanon, where important and articulated hydraulic systems – basins, bathtubs, pools, channels – have been brought to light, becoming in some ways the main hallmarks of the sanctuaries themselves. The main goal of the present paper is to investigate the ways in which the water supplies and use were organized, specifically with religious purposes, as well as the related symbolic dimension. Through archaeological and textual documentation, it will attempt especially to answer some fundamental questions: is water to be understood as the object and purpose of worship? Or is it to be conceived as a means and instrument of cultic actions? Or, again, are it the setting and the place chosen for the performance of rituals in the sanctuary? And, above all, to what extent is possible to separate, in practice and symbolism, these different connotations?
Impossible généalogie littéraire de René Maran
Authors: Allouache Ferroudja
Published: October 2021

La fortune d’un livre et le destin d’un auteur dépendent souvent des commentaires qu’en assurent les chroniqueurs. Bien qu’elle relève d’un jugement de goût, de réactions à chaud, la critique journalistique a une large responsabilité dans la réception d’une œuvre. Notre intervention s’intéresse à la manière dont les critiques bricolent pour évincer Maran et son personnage Batouala de la mémoire de la littérature telle qu’elle est en train de « se faire » à travers la presse de l’époque coloniale (journaux et revues de 1921-1922). Elle interroge aussi la place que lui accordent a posteriori les anthologies littéraires françaises et francophones.
Un homme pareil aux autres de René Maran au prisme des études génétiques
Authors: Blasi Laura Gauthier , Harpin Tina
Published: October 2021

Un homme pareil aux autres de René Maran est un roman connu pour son intrigue amoureuse et son inspiration autobiographique. Mais c’est aussi un texte qui a été constamment réécrit des années 1920 jusqu’à sa version définitive en 1947 aux éditions Arc-en-ciel. Ce roman a connu plusieurs vies imprimées et plusieurs titres depuis la parution d’un extrait du Roman d’un nègre dans la revue Je sais tout du 15 novembre 1924, l’édition de Journal sans date dans la revue littéraire Œuvres libres en juin 1927 puis celle de Défense d’aimer dans la revue les Feuillets littéraires d’Arthème Fayard en 1932. Le travail de réécriture visible entre les versions imprimées et l’accès aux manuscrits de l’auteur invitent à une réflexion sur l’œuvre d’un point de vue génétique. Cet article se propose de faire un point sur l’histoire du texte en présentant un dossier génétique constitué de manuscrits non datés et que nous avons tenté de classer.

« Fantaisies lusitaniennes » : histoires d’un musée et de l’homme qui s’opposa aux ultra-lusos
Authors: Leandro Sandra
Published: October 2021

Cet essai est divisé en deux parties : une première, où nous contextualisons et abordons quelques lignes de force de la pensée de l’historien de l’art Joaquim de Vasconcelos (1849-1936) ; une deuxième où nous présentons le Museu industrial e comercial de Porto, aujourd’hui disparu. Vasconcelos souhaitait que ce musée fût un instrument efficace pour former des étudiants et des ouvriers via l’observation et le design, afin de favoriser la production d’objets manufacturés. Dans le but de présenter de bons modèles, il le conçut à la fois comme un musée d’ethnographie et comme un musée de proto-design. Il pensa aussi cette institution comme un moyen de faire la promotion de l’économie, par la valorisation des fabriques et des produits industriels nationaux. Il était toutefois loin d’être un nationaliste conventionnel. Rompu à des critères internationaux, il essaya de démanteler l’appropriation nationaliste du style manuélin, questionna la notion de frontières dans l’art et se déclara contre les ultra-lusos pour lesquels l’origine nationale primait la qualité esthétique.
Images postcoloniales : de la révolution des Œillets aux processus d’indépendance. Ouvrages de propagande, de résistance et de liberté (1974-1984)
Authors: Lourenço Marques Susana
Published: October 2021

À partir de l’étude du rapport indissociable entre histoire et photographie, ainsi que des formes de hiérarchisation des pouvoirs déterminant leur production et leur archivage, cet article analyse les images de la fin de l’empire colonial portugais, publiées dans des ouvrages de propagande et de contestation, de 1974 à 1984. Il offre une lecture comparative des contextes angolais et mozambicain. Caractériser les mécanismes de diffusion et de réception des images dites postcoloniales permet de reconsidérer leur dimension éthique et politique et de mieux appréhender le rôle de l’image dans la représentation de ce processus dans diverses parties du monde. La lecture croisée d’une sélection d’ouvrages éminemment photographiques tels que Resistência popular generalizada (Angola), Da resistência à libertação (Mozambique) ou Imagens de uma revolução (Portugal), éclaire la manière dont ils ont mis en relation deux forces apparemment opposées qui se sont mutuellement renforcés : l’indépendance des territoires et des peuples colonisés et la fin du régime dictatorial qui les opprimait.

La spirale interprétative d’un serpent mississippien
Authors: BALLOY Benjamin
Published: October 2021

Le motif du serpent enroulé et monstrueux est présent sur de nombreux pendentifs découverts en contexte d’inhumation dans les tertres de la période mississippienne (xiiie-xvie siècles) en Amérique du Nord. L’article propose de rapprocher ce décor des êtres aquatiques, amants équivoques voire franchement violeurs, qui peuplent les traditions narratives autochtones en Amérique du Nord, et notamment celles recueillies à partir du xviie siècle dans le Sud-Est. En privilégiant ce motif, il se pourrait que les individus éminents dans ces sociétés hiérarchisées aient cherché à s’identifier à ces amants monstrueux ou à leur progéniture.
Amours d’outre-tombe
Authors: MALIVIN Amandine
Published: October 2021

La révélation au public de faits de cohabitation avec des restes humains, et l’attachement particulier éprouvé par un vivant à leur égard, qu’ils soient motivés par des sentiments amoureux, de la tendresse, ou par un désir sexuel, suscitent toujours une forme de malaise. Mais la restitution de ces affaires et leur perception par les observateurs extérieurs varient fortement selon les circonstances, allant du rejet violent et de la répulsion à une forme d’indulgence et de compassion. C’est cette ambivalence que cherche à mettre en avant cet article, ainsi qu’à interroger les raisons qui peuvent l’expliquer. Il sera donc ici question de savoir ce qui contribue à définir la légitimité des restes humains comme objets d’attachement et de désir.

Digital Crisis Communication Management
Authors: Özer Deniz , Çerçi Ümmü Özlem
Published: October 2021

Public relations is a communication process managed strategically and in a planned way. It includes all internal and external communication activities of institutions, including communicating with the target audience, providing information, creating an institutional image. Institutions face uncertainties, unexpected situations, and dangers in times of crisis; they make an effort to seize every opportunity to cope with these. Under changing conditions outside of the normal order, institutions have to act strategically. Institutions that do not care about these strategic studies will have less chance of success. Gaining and maintaining the trust of the internal and external stakeholders of the institution is much more important in times of crisis. The aim of the study is to reveal how crisis communication is handled in the digital environment, also called new media, in the COVID-19 pandemic that affects the whole world. In the study, communication activities of the Ministry of Health of the Turkish Republic will be investigated.
Ecosystem Services for Environmental Sustainability
Authors: Dwarapureddi Bhavya Kavitha , Dash Swathi , Vara Saritha
Published: October 2021

Many of the most valuable contributions of ecosystems to human wellbeing are ecosystem services and are generally underrepresented in assessments. Indirect and direct factors including biophysical dynamics like soil properties, changing climatic conditions, plant functional structures, and anthropogenic activities like changes in land use and land degradation reduce ecosystem services. It is challenging and important to identify these factors and also to estimate their relative contributions to the degradation of ecosystem services. The chapter is an attempt to identify all these important factors and also suggest ways to enhance ecosystem services. Furthermore, incorporation of local knowledge would enable quantifying ecosystem services at a greater spatial resolution and also help in identifying chief factors influencing ecosystem service delivery. Furthermore, a long-term program needs to be established for gathering data towards streamlining ecosystem services wherein involvement of stakeholders is necessary for designing payments for these programs.
Tourism, Entrepreneurship, and Sustainability
Authors: Nóbrega Mariana , Sousa Mariana , Ribeiro João do Vale , Szczygiel Nina
Published: October 2021

The new global economy and its branches need to be both sustainable and entrepreneurial. In the world where finitude of resources can be eye-witnessed, decisions that lay upon the principles of people, profit, and planet have the ability to preserve the quality of life of present and future generations. Tourism is one of those sectors which have largely expanded over the past decades and whose development affects countries, economies, and natural resources. Sustainable tourism appears to be a natural fit for entrepreneurs wishing to establish new ventures and pursue business opportunities in today's dynamic yet complex business climate. This chapter examines the nexus between entrepreneurship and sustainable tourism. On the basis of theoretical framework and the review of relevant global environmental and tourism-specific tendencies, an online empirical study was conducted to understand how young adults perceive entrepreneurship and sustainability in tourism and the contribution of the two to sustainable development.
Mapping Plastic Greenhouses With LANDSAT 8 Imagery in Valparaiso, Chile
Authors: Aguirre Ignacio , Garrido Velarde Jacinto , Parra Javier Lozano
Published: October 2021

In the last decades there has been a strong increase around the world in the use of plastic greenhouses (PGs). The Valparaíso region, in the central valley of Chile, has not been the exception, and the area covered by greenhouses has also experienced an increase over the years, reaching 1180 ha in 2007. Taking into account that agriculture in this region employs more than 60,000 people and accounts for 4% of the regional GDP, this information should be available to be included in territorial planning and incorporated into hydrological, economic, and food security models. To do this, the authors propose a new method for identifying the surface covered by PGs based on the intersection of the normalized difference indices and the areas excluded by the masks. The results showed that this methodology was able to identify with a general precision of 86.25% which allowed to classify 1409.85 ha. This area is consistent with the agricultural census carried out in 2007 and with the increase of more than 900 subsidies granted by the government for the installation of new structures.
Data Envelopment Analysis and Analytics Software for Optimizing Building Energy Efficiency
Authors: Radovilsky Zinovy , Taneja Pallavi , Sahay Payal
Published: October 2021

This research was motivated by the need to identify the most effective Data Envelopment Analysis (DEA) model and associated data analytics software for measuring, comparing, and optimizing building energy efficiency. By analyzing literature sources, the authors identified several gaps in the existing DEA approaches that were resolved in this research. In particular, the authors introduced energy efficiency indices like energy consumption per square foot and per occupant as a part of DEA models’ outputs. They also utilized inverse and min-max normalized output variables to resolve the issue of undesirable outputs in the DEA models. The evaluation of these models was done by utilizing various data analytics software including Python, R, Matlab, and Excel. The authors identified that the CCR DEA model with inverse output variables provided the most reliable energy efficiency scores, and the Python’s PyDEA package produces the most consistent efficiency scores while running the CCR model.

Corporate Social Responsibility (CSR) turned out to be considered as an efficient marketing tool. However, the impact of CSR on loyalty is still uncultivated. The present paper investigates the influence of CSR activities on both loyalty constructs: attitudinal loyalty as well as behavioral loyalty. Based on a sample of 203 Lebanese students, results revealed a considerable effect of ethical, legal and philanthropy social responsibility on both attitudinal and behavioral loyalty. Conversely, the effect of economic responsibility on attitudinal and behavioral loyalty was insignificant.
Search and Compare Drives Satisfaction

Published: October 2021

Ability to easily search and then compare items is an advantage that online platforms have over bricks and mortar formats. In such an intensely competitive airline market, this paper investigates if this exploration experience satisfies the traveler during air ticket booking, by applying the stimulus organism response model. An empirical study is used to test the proposed model by applying the structural equation modeling and interaction effects. The model describes the extent by which traveler’s repurchase intention is influenced by four important factors – search and compare assortment satisfaction, social influence and overall satisfaction. The paper extends the satisfaction to online repatronage intention and customer loyalty. This empirical study also establishes that the relationships are moderated due to civil status and ticketing number of platforms used by the customers.

In this age of digitalization, when every industry is undergoing technological disruption, there is a big role of digital gadgets and technology products. A key feature of these digital gadgets is the short length of the product life cycle, since the newer and more advanced generations of technologies are developed regularly to replace the earlier conventional technologies. The traditional EOQ models that assume a constant demand cannot be used here. This research paper formulates an inventory optimization model for the multi-generational products under the trade credits and the credit-linked and innovation diffusion dependent demand. The study also performs a numerical illustration of the proposed model, and establishes important dynamics among the key variables. It also performs the sensitivity analysis with the cost of credit and the trade credit period. The paper concludes with the managerial implications for the inventory practitioners and the possible areas of extension for this research in the future.

Students enter college with widely varying levels of preparation. This is especially visible to faculty and administrators tasked with ensuring student success in core STEM courses and helping underrepresented students succeed. Flexible support strategies are needed. They must be timely and measurable so that limited funds can be optimally allocated. This paper reviews a program that addresses these concerns and is translatable to many higher education settings and disciplines. It is situated in a physics department at a large public research university in an urban city in the southern United States. A group of rotating faculty improved the success rate in an introductory physics course for non-physics majors. A diagnostic exam is used to assess students’ preparation in order to assign some to a peer-led supplementary recitation. An overview of program implementation and results is shared, along with strategies and suggested solutions to further address gaps in success rates in order to provide all students an equitable university experience and chance of success.

Published: October 2021

Cloud computing has recently emerged as a new model for hosting and delivering services over the internet. Cloud computing has many advantages, such as the ability to increase capacity or add capabilities without the need to invest in new infrastructure. It can also fulfil technological requirements in a fast and automated manner. In recent years, cloud computing has changed the IT industry; in fact, it is one of the industry's fastest growing phenomena. However, as more information about people and businesses becomes available in the cloud, concerns about the safety of this environment will increase. In addition, some challenges to the use of this service exist. This paper presents the results of a survey about cloud computing and outlines the main concepts of the technology along with examples of appropriate usage. It also discusses resource management issues such as service level agreements and highlights the challenges faced by users when choosing cloud computing services.

Some point out that the influence of YouTube's video recommendation algorithm is causing users to be exposed to only video clips in limited subjects or fields, especially to biased content with opinions that are tilted to one side. However, there is a lack of empirical research on filter bubbles as algorithms in YouTube have not been disclosed. This study indirectly demonstrated the phenomenon of filter bubble on YouTube by extracting comment-based content network between uploaders who posted videos and writers who wrote comments on the video by each subject of the contents. Also, this study analyzed communication patterns between users through social network analysis (SNA). According to the analysis, users' narrow information acquisition and communication phenomenon caused by the filter bubble in YouTube was found.

The article discusses the features of biomimetics as a science that allows to suggest technologies for creating new technologies. Strange to relate, the man is a being completely unadapted to life. At the same time, man made a lot of discoveries precisely thanks to the observation of animals — from primitive tools based on the teeth of other animals to the first flying machines. Over time, the human civilization has defined a whole direction in science, which explores mechanisms in nature in order to use them for the benefit of man. With the help of biomimetics (from the Latin "bios" - life and "mimesis" - imitation), many problems from medicine, architecture, transport and energy were solved.
Correction of the Full-text : An Investigation into Sea Level Rise in Sri Lankan Waters with Satellite Altimetry published on 01st October 2021 in the same issue Vol.1(2) 2021 Original article

Most of the socio-economic activities of Sri Lanka are centred in the coastal regions,  which  can  be  described  according  to  its  unique  geographical  and geophysical  backgrounds.  It  is  estimated  that  Sri  Lanka  has  a  shore  line about  1,700  km  in  length.  Therefore,  better  knowledge  and  understanding of the characteristics of sea level is very essential. The sea level has traditionally  been  measured  mainly  at  tide  gauges  set  up  along  the  coast line. However, the number of tide gauge stations is few and sparse in most countries. But, with the advancements of satellite altimetry technology, it is now  accepted  as  an  alternative  technique  to  study  regional  and  global  sea level changes. The basic concept in altimetry is the range measurements to the water surface measured from the altimeter antenna. The surface of the sea,  or  sea  level,  is  continuously  changing  for  many  reasons.  Here,  some changes are fast whereas others occur gradually. Among them, some factors  are  natural causes,  while  others  occur  due  to  man-made  activities such as the greenhouse effect. These changes can be regional or extend at a global scale. The main aim of this research was to examine the trends in sea level  rise  around  the  Sri  Lankan  coastline  using  two  decades  of  satellite altimetry data  from  1993  to  2012.  The  computed  sea  level  rise  trends around  Sri  Lanka are around  2.5  to  3  mm  per  year,  with  a standard deviation  of  +/-  0.6  mm.  The  obtained  trend  of  sea  level  rise  from  the altimetry data was validated with tide gauge data in Colombo, and found to be  highly  correlated,  with  a  correlation  coefficient  (R2)  of  0.93  for  annual mean sea level. This study confirms that satellite altimetry can be successfully used to investigate the long term sea level trend studies, particularly in the absence of long term tide data.
Impact of Smartphone Addiction on Academic Performance of Undergraduates in Sri Lanka: Mediating effect of Technology Driven Multitasking

Published: October 2021

This study aimed to examine university undergraduate’s level of Smartphone Addiction (SA) and to investigate the impact of SA on their Academic Performance (AP) with the mediating effect of Technology-Driven Multitasking behaviour (TDMT). The study employed a cross-sectional survey design, with data gathered from 315 university students. The scope is limited to management undergraduates in Sri Lanka. Descriptive and inferential analysis was used while regression analysis was applied to test hypotheses. Further, the Sobel test is used to test the mediate effect in the relationship between Independent Variable (IV) and Dependent Variable (DV. The study put forth that university students were highly addicted to the use of smartphones. SA negatively impacts AP while TDMT also negatively impacts DV. Further, TDMT mediates the relationship between IV and DV. This study suggests that the students should reduce the intense use of smartphones for smoothly doing their academic activities.
