ANALISA PERBEDAAN CITRA DESTINASI PENDUDUK LOKAL DAN WISATAWAN, DAN IMPLIKASINYA BAGI PEMASARAN WISATA JAKARTA
Authors: Budi Budi
Published: June 2019

Destination image is an important factor in tourism marketing. Harmonious destination image between local residents, tourists, and Tourism Marketers Organization allows for a sustainable development model for tourism marketing. This study aims to examine differences of Jakarta's destination image in the perception of tourists and local residents. Methodology used is quantitative research. Research instruments are developed by reviewing relevant literature on destination image factors for Jakarta. Data collection is done through questionnaires distributed online. Different test conducted is Mann-Whitney test. Results show that local residents and tourists have similar destination image about culinary tourism and shopping. But they have different destination image about recreation, cultural tourism, beach tourism, historical tours, local people, infrastructure, affective destination image, and conative destination image. Researcher suggested to Tourism Marketers and Tourism Department of Jakarta to educate, to give information, and to involve local people especially to destination images that still considered low by local residents. Tourism Marketer Organizations, Jakarta Tourism Office, and Local Residents must maintain and even improve the quality of culinary tour and shopping experience so as to increase the satisfaction of tourists when visiting Jakarta, which in turn will make tourists want to re-visit.

EARLY WARNING SYSTEM IN MANAGING WATER INFRASTRUCTRE PROJECTS
Authors: Sjekavica Klepo Mariela , Radujković Mladen
Published: June 2019

There is a continuous need to improve existing project management decision-making support models, particularly those for monitoring and control are needed to increase chances for success. In this paper, potential of early warning in project management was focused, along with its connection to project success via project success factors. First, a systematic literature review was conducted, along with the focus group method, in order to identify project success factors. The selected success factors were also collected on 93 water infrastructure projects through a survey. By the means of linear regression analysis, critical success factors were finally determined. The results were integrated in the early warning system algorithm, composed by three modules – detection, validation and response module. The response module is composed by three dimensions: 1) risk, constraint and change management, 2) incorporation of project management competences and 3) application of project management methods, tools and techniques. The proposed early warning system was tested on three infrastructure projects. The results confirmed that improved early warning system can contribute in increase of project management success. As original database is composed by projects from only one country (Croatia), in the final stage of the research proposed approach was checked in five countries from the Central or South East Europe (Czech Republic, Slovenia, Serbia, North Macedonia, Bosnia and Herzegovina). The results from the final stage confirmed potential of the proposed approach as declared originally, so it is reasonable to expect success in early warning system’s implementation due to similarities of critical success factors on projects as well as project management problems in general, that countries in regions share. This research presents new and creative way in linking early warning and project success, as well as interpretation of early response through different dimensions in project management. Also, based on the results of this research, it is possible to create a useful practical tool for managing other types of projects.

Published: June 2019

In the context of increasing traffic demands and emerging mobility trends road infrastructure has to shift towards the fifth generation of roads, which according to Forever Open Road (FOR) vision are envisioned as adaptable to traffic volumes, resilient to changing weather conditions, quickly built, effectively maintained, suitable for retrofitting, self-monitoring, self-repairing and recyclable. Concrete modular pavements can be defined as an example of such type of road infrastructure. Functional needs are mainly associated with implementation area/location, traffic and mobility demands, environmental constraints and etc. This also has a significant impact on the selection of Precast Concrete Pavements (PCP) texture formation method and materials. Concrete pavement surface texture affects both safety and tyre/road noise characteristics. Exposed Aggregate Concrete (EAC) and porous concrete are the most suitable noise reducing solutions for highways and streets wearing layer even in severe traffic and climate conditions. According to the literature analysis, the algorithm of highways and streets low noise concrete design was created. It is recommended to use the highest quality aggregates with maximum size up to 8 mm, gap-graded gradation, higher amount of cement and lower water/cement ratio. The most important characteristics of EAC are Mean Profile Depth (MPD), Mean Texture Depth (MTD) and profile count, while the most important characteristics of porous concrete are compressive strength, outflow and air void content.

We analyze in this work the propagation and geoeffectiveness of four successive coronal mass ejections (CMEs) that erupted from the Sun during 2013 May 21–23 and were detected in interplanetary space by the Wind and/or STEREO-A spacecraft. All these CMEs featured critical aspects for understanding so-called “problem space weather storms” at Earth. In the first three events a limb CMEs resulted in moderately geoeffective in situ structures at their target location in terms of the disturbance storm time (Dst) index (either measured or estimated). The fourth CME, which also caused a moderate geomagnetic response, erupted from close to the disk center as seen from Earth, but it was not visible in coronagraph images from the spacecraft along the Sun–Earth line and appeared narrow and faint from off-angle viewpoints. Making the correct connection between CMEs at the Sun and their in situ counterparts is often difficult for problem storms. We investigate these four CMEs using multiwavelength and multipoint remote-sensing observations (extreme ultraviolet, white light, and radio), aided by 3D heliospheric modeling, in order to follow their propagation in the corona and in interplanetary space and to assess their impact at 1 au. Finally, we emphasize the difficulties in forecasting moderate space weather effects that are provoked by problematic and ambiguous events and the importance of multispacecraft data for observing and modeling problem storms.
Constraints Imposed by the Square-root Spin-down Law on Coronal Wind Parameters
Authors: Skumanich Andrew
Published: June 2019

We derive an explicit expression for the coronal wind mass-loss rate in terms of either the surface field or the surface rotation rate. This result is based on a currently used generalized torque interpolation formula (per unit rotational velocity) expressed as a product of known monomials, separately for the magnetic field and the mass-loss rate. The latter is assumed here to be given by an unknown monomial power of the magnetic field. This yields a torque dependent solely on the magnetic field that must yield the square-root spin-down law. A monomial field-rotation relation, defining the rotational power index for the field, is derived from the congruity of the decay with age of the observed Ca ii emission luminosity (with an arbitrary magnetic field power dependence) with the decay with age of the rotational velocity. This allows one to express the mass-loss rate power index in terms of the rotational index. We apply this constraining equation to a variety of observations. We find that even though there is considerable scatter in the data, there is sufficient observational evidence for the reality of a linear field-rotation relation associated with a linear temporal decay of the mass-loss rate.
Multimessenger Implications of AT2018cow: High-energy Cosmic-Ray and Neutrino Emissions from Magnetar-powered Superluminous Transients
Authors: Fang Ke , Metzger Brian D. , Murase Kohta , Bartos Imre , Kotera Kumiko
Published: June 2019

Newly born, rapidly spinning magnetars have been invoked as the power sources of superluminous transients, including the class of “fast blue optical transients” (FBOTs). The extensive multiwavelength analysis of AT2018cow, the first FBOT discovered in real time, is consistent with the magnetar scenario and offers an unprecedented opportunity to comprehend the nature of these sources and assess their broader implications. Using AT2018cow as a prototype, we investigate high-energy neutrino and cosmic-ray production from FBOTs and the more general class of superluminous supernovae (SLSNe). By calculating the interaction of cosmic rays and the time-evolving radiation field and baryon background, we find that particles accelerated in the magnetar wind may escape the ejecta at ultrahigh energies. The predicted high-energy neutrino fluence from AT2018cow is below the sensitivity of the IceCube Observatory, and estimates of the cosmically integrated neutrino flux from FBOTs are consistent with the extreme-high-energy upper limits posed by IceCube. High-energy γ rays exceeding GeV energies are obscured for the first months to years by thermal photons in the magnetar nebula, but are potentially observable at later times. Given their potentially higher volumetric rate compared to other engine-powered transients (e.g., SLSNe and gamma-ray bursts), we conclude that FBOTs are favorable targets for current and next-generation multimessenger observatories.
Application of the Electromotive Force as a Shock Front Indicator in the Inner Heliosphere
Authors: Hofer Bernhard , Bourdin Philippe-A.
Published: June 2019

The electromotive force (EMF) describes how the evolution and generation of a large-scale magnetic field is influenced by small-scale turbulence. Recent studies of in situ measurements have shown a significant peak in the EMF while a coronal mass ejection (CME) shock front passes by the spacecraft. The goal of this study is to use the EMF as an indicator for the arrival of CME shock fronts. With Helios spacecraft measurements we carry out a statistical study on the EMF during CMEs in the inner heliosphere. We develop an automated shock front detection algorithm using the EMF as the main detection criterion and compare the results to an existing CME database. The properties of the EMF during the recorded events are discussed as a function of the heliocentric distance. Our algorithm reproduces most of the events from Kilpua et al. and finds many additional CME-like events, which proves that the EMF is a good shock front indicator. The largest peaks in the EMF are found from 0 to 50 minutes after the initial shock. We find a power law of −1.54 and –2.18 for two different formulations of the EMF with the heliocentric distance.

We report the discovery of soft X-ray pulsations from the nearby millisecond pulsar PSR J1231−1411 using the Neutron Star Interior Composition Explorer (NICER). The pulsed emission is characterized by a broad and asymmetric main pulse and a much fainter secondary interpulse, with a total pulsed count rate of 0.055 c s−1 in the 0.35–1.5 keV band. We analyzed Fermi Large Area Telescope (LAT) data to update the pulse timing model covering 10 yr of data and used that model to coherently combine NICER data over a year of observations. Spectral modeling suggests that the flux is dominated by thermal emission from a hot spot (or spots) on the neutron star surface. The phase relationship between the X-ray pulse and the radio and γ rays provides insight into the geometry of the system.
Molecular and cytogenetic differentiation within the Lariophagus distinguendus (Förster, 1841) species complex (Hymenoptera, Pteromalidae)

Published: June 2019

Several strains of the apparently well-known cosmopolitan synanthropic parasitoid of coleopteran stored-product pests, Lariophagusdistinguendus (Förster, 1841) from Western Europe, were studied using DNA sequencing and chromosomal analysis. The presence of at least two cryptic species with different COI sequences and chromosome numbers (n = 5 and 6) was supported. The species with n = 6 is associated with the drugstore beetle Stegobiumpaniceum (Linnaeus, 1758), whereas the other one with n = 5 mostly develops on the granary weevil Sitophilusgranarius (Linnaeus, 1758). A phylogenetic study revealed that the karyotype with n = 6 represents an ancestral character state in this complex. Consequently, the chromosome set with n = 5 which is characteristic of a particular internal clade, apparently originated via chromosomal fusion which was probably preceded by a pericentric inversion. If this is true, inverted chromosome segments could accumulate a number of genetic loci responsible for certain interspecific differences.
Faire l’histoire du service du travail obligatoire des origines à nos jours : généalogie et avancées

Published: June 2019

Raphaël S pina , Faire l’histoire du STO des origines à nos jours : généalogie et avancées Le STO fut un tournant crucial de l’Occupation, mais il est resté longuement sous-étudié. Dès l’Occupation puis dans l’immédiat après-guerre, des historiques ont cependant bien discerné les étapes des réquisitions de main-d’œuvre et dressé des statistiques précieuses. Depuis les années 1960-1970, des recherches ont cerné le STO au niveau départemental voire régional, mais chaque territoire a ses spécificités. Les visions d’ensemble ont été plus tardives. Patrice Arnaud fut le premier à dresser le panorama global de la vie des travailleurs civils dans toute l’Allemagne, dans l’ensemble de ses dimensions. Enfin notre propre thèse, publiée récemment, s’est voulue la première synthèse scientifique sur l’ensemble des enjeux politiques, économiques et sociaux du STO, de la genèse à la mémoire en passant par les perceptions de l’opinion publique.
« Souvenir d’une petite amie de captivité » : ouvrières françaises et prisonniers de guerre à Berlin entre 1940 et 1945
Authors: Fauroux Camille
Published: June 2019

Camille F auroux , « Souvenir d’une petite amie de captivité » : ouvrières françaises et prisonniers de guerre à Berlin entre 1940 et 1945 À partir d’archives judiciaires conservées à Berlin, cet article montre l’existence d’échanges, de relations d’entraide, d’amitié et parfois de liaisons amoureuses entre les ouvrières françaises venues volontairement en Allemagne et les prisonniers de guerre. Ces expériences oubliées amènent à s’interroger sur le déni des prisonniers de guerre, qui à leur retour en 1945 affirment avoir évité soigneusement tout contact avec ces femmes durant leur captivité. Plus profondément, la mise en évidence d’un angle mort de la mémoire des militaires emprisonnés permet de saisir la façon dont les dichotomies genrées qui structurent les discours sur les expériences de la guerre et de l’Occupation dès 1945 pèsent encore sur la représentation que nous nous faisons du passé.
Un Français en Allemagne : le commissaire Louit, des geôles de la Gestapo au Comité français de rapatriement (Berlin, 1942-1945)
Authors: Joly Laurent

Laurent J oly , Un Français en Allemagne : le commissaire Louit, des geôles de la Gestapo au Comité français de rapatriement (Berlin, 1942-1945) Des quelque 100 000 citoyens français présents à Berlin au moment de l’effondrement du Troisième Reich en avril 1945, Christian Louit (1899-1977) n’est assurément pas celui qui a le parcours le plus banal. Commissaire de police arrêté par la Gestapo et envoyé à Berlin trois ans plus tôt afin d’être questionné sur différentes affaires politiques, il a passé plus de deux ans en prison. Échappant de peu à la mort, il est libéré miraculeusement au début de l’année 1945. En avril, avec un groupe de Français, il fonde un « Comité de rapatriement » qui remplace, à la suite d’une étonnante passation de pouvoirs, la délégation de Vichy à Berlin. La découverte des papiers privés de Christian Louit permet de jeter une lumière neuve sur la situation des Français dans la capitale du Reich à la veille de leur rapatriement en France.

Christophe W oehrle , De la captivité au travail forcé ? Le cas des prisonniers de guerre juifs Cinq millions de Français sont mobilisés à la fin de l’été 1939, 1 800 000 sont fait prisonniers. Parmi eux, entre 10 000 et 15 000 juifs sont envoyés au service de l’économie du Reich à l’intérieur des frontières allemandes. Protégés par la Convention de Genève, ils échappent au destin funeste de leurs coreligionnaires. Avec les déportés, les requis du Service du Travail Obligatoire, les coloniaux, le cas des prisonniers de guerre juifs montre que les catégories des Français captifs ne s’envisagent pas comme un ensemble uniforme de victimes.
Un symbole de l’engagement féminin dans la Grande Guerre : Bécassine
Authors: Bonin Hubert
Published: June 2019

Hubert B onin , Un symbole de l’engagement féminin dans la Grande Guerre : Bécassine La collection de bandes dessinées autour du personnage de Bécassine (parue dans un magazine et en albums) est révélatrice de l’évolution des mentalités, de la société, des mœurs de part et d’autre de la Première Guerre mondiale. Or ce personnage populaire, mal dégrossi au contact de la vie dans les grandes villes et parfois même naïf, se retrouve confronté aux retombées du conflit dans la vie quotidienne, tant des bourgeoisies que du peuple. Bécassine participe même en direct aux formes du travail de quasi-mobilisée ou se retrouve insérée dans des aventures au plus près de la vie militaire. On comprend que nombre d’éléments aient pu être puisés dans cinq albums afin de nourrir une étude de cas académique, plutôt centrée sur la rupture socio-mentale imposée par la guerre dans nombre de strates de la société.
Minorités, discrimination et reconnaissance
Authors: Möser Cornelia
Published: June 2019

Partant du constat que les politiques sexuelles institutionnalisées aujourd’hui en France, en Allemagne et aux États-Unis sont majoritairement basées sur un modèle de politique antidiscriminatoire, cet article propose un retour sur l’histoire des luttes et théories féministes et homosexuelles. À l’exemple de trois débats clés qui ont marqué les manières féministes et queer de penser la sexualité, des alternatives au modèle d’antidiscrimination sont discutées en vue de leur potentiel émancipateur. Le premier débat concerne un groupement de folles politique à Berlin au début des années 1970 et tourne autour d’un lien éventuel entre la domination masculine et l’oppression des homosexuel·le·s. Le deuxième débat discute le potentiel stratégique du lesbianisme politique. Le troisième débat surnommé sex wars concerne la pornographie ainsi que les subcultures lesbiennes sadomasochistes et butch/fem , et interroge la tension entre plaisir et danger dans la sexualité pour les femmes. À travers ces trois débats, nous pouvons suivre comment les acceptions de ce qu’est la sexualité changent. Chaque fois genre et sexualité sont liés d’une manière différente. Par ces analyses l’article contribue à contredire une « histoire des vainqueurs » qui partirait de l’idée que, puisque les politiques antidiscriminatoires sont les plus répandues aujourd’hui, elles seraient la forme la plus pertinente pour combattre l’oppression des dissidences sexuelles.
La « communauté homosexuelle » comme peuple transnational
Authors: Broqua Christophe
Published: June 2019

L’usage de la notion de « communauté homosexuelle » est courant depuis de nombreuses décennies dans les pays d’Amérique du Nord et d’Europe. D’une catégorie tout d’abord descriptive, la « communauté homosexuelle » s’est progressivement transformée en « fiction politique ». En dépit de l’évidence selon laquelle il n’existe pas de « communauté homosexuelle » à la fois homogène et aisément délimitable, voire séparable, du reste de la société, la désignation d’un groupe homosexuel supposé au travers de cette expression a des effets politiques bien « réels », en termes tant de représentation politique que de représentation de soi, chez une partie au moins des individus potentiellement concernés. Un fil historique permet ici d’éclairer les principaux enjeux du recours à la notion de « communauté homosexuelle » et de suivre leur développement finalement international. Les ressorts et les finalités de cette opération de désignation diffèrent selon les contextes et selon que la « communauté » est invoquée positivement ou stigmatisée, mais cette opération vise partout à produire, désormais à l’échelle transnationale, une catégorie publique dont la consistance supposée se heurte souvent à la diversité des expériences sociales et politiques.
Carthage et le contrôle des littoraux africains : les deux premiers traités romano-carthaginois
Authors: Zelanti Alain
Published: June 2019

Les deux premiers traités entre les Carthaginois et les Romains, datés respectivement de 509 et de 348 avant notre ère, ont été transmis, de manière partielle, par l’historien grec Polybe et l’interprétation du premier est difficile. Cependant, en le replaçant dans le contexte des relations très anciennes entre les Carthaginois et les cités étrusques, attestées tant par les auteurs anciens que par l’archéologie, il est possible d’accepter la datation haute donnée par Polybe. La première difficulté est d’identifier les différents caps mentionnés dans le traité, en particulier le Beau Promontoire, le Καλὸνἀκρωτήριον du texte polybien, en évoquant l’historiographie de la question. Les Carthaginois se souciaient de protéger certains rivages africains de la fréquentation des navires étrangers, éventuellement romains, dans un contexte de fortes tensions avec les Grecs. Les traces archéologiques de fortifications puniques sur le littoral du Cap Bon le confirment. Les espaces interdits à la navigation varient entre le premier et le deuxième traité, ce qui reflète l’évolution des rapports de Carthage avec son arrière-pays et avec les cités d’Utique et de Tyr, ainsi que l’accroissement des capacités maritimes romaines. Les restrictions énoncées permettaient aux Carthaginois de contrôler la circulation des étrangers dans une grande partie de leur zone d’influence et de surveiller les activités commerciales. Les ports puniques étaient alors réservés aux marchands carthaginois. Les traités définissaient donc des espaces ouverts et des espaces fermés à la navigation, qui ressemblent aux clauses commerciales qui existaient à la même époque dans le monde grec.
L’émergence d’un nouveau profil de formateurs : les personnes accompagnées
Authors: Jaeger Marcel
Published: June 2019

La participation des personnes accompagnées et aidées aux dispositifs mis en place en leur faveur connaît une nouvelle forme. Après une participation à la vie des institutions et leur association à l’élaboration des projets qui les concernent, ces personnes sont de plus en plus impliquées dans la formation des travailleurs sociaux. Au-delà de l’expression de leur souffrance et au-delà des témoignages ou récits de vie qui peuvent éclairer les professionnels pour leurs interventions, les « usagers » sont reconnus pour leurs compétences, voire leur expertise. Par étapes successives, leur implication ne cesse de croître dans les lieux de formation, mais aussi dans la recherche en travail social.

Les savoirs expérientiels : entre objectivité des faits, subjectivité de l’expérience et pertinence validée par les pairs
Authors: Gardien Ève
Published: June 2019

Cet article revient tout d’abord sur les savoirs expérientiels pour montrer en quoi ils concernent l’expérience du réel de tout un chacun. Dans un deuxième temps, les raisons de la rareté et de la spécificité des savoirs issus de l’expérience des situations de handicap ou encore liées à la maladie chronique ou aux troubles de santé mentale sont expliquées. Ensuite, les modalités de production de ces savoirs spécifiques sont explorées pour discuter un point au cœur du débat portant sur leur légitimité : les savoirs expérientiels sont-ils objectifs ? De cette dernière analyse découlera l’importance décisive d’une production de savoirs situés, depuis l’intérieur de l’expérience de situations spécifiques, sur la base d’échanges entre pairs.

Les co-formations par le croisement des savoirs, portées par atd Quart Monde, constituent un mode de formation des professionnels de l’intervention sociale qui associe à égalité praticiens et personnes en situation d’exclusion sociale. Ces dernières s’appuient sur leurs savoirs expérientiels, travaillés en amont, pour faire évoluer les pratiques des intervenants sociaux. Après avoir interrogé la manière de désigner les publics de l’intervention sociale, l’article creuse la question du savoir expérientiel, décrit les principes d’une co-formation et en esquisse les effets sur les pratiques de travail social.
Enjeux, modalités et conditions de la participation dans les formations en travail social : états des pratiques en France et en Europe
Authors: Lebailly Philippe
Published: June 2019

Cet article présente les enseignements d’expériences développées en France et en Europe, en particulier dans le cadre du réseau PowerUs, et d’un projet européen Interreg porté par quatre instituts de formation des régions pyrénéennes Occitanie et Catalogne. Deux enjeux essentiels de la participation sont présentés : la reconnaissance des savoirs expérientiels comme savoirs à part entière et la réduction des écarts entre les professionnel.le.s et les personnes concernées (référence au concept de mending the gap de PowerUs). Une typologie des différentes modalités repérées dans les pratiques de participation visera à montrer la diversité et la richesse des expériences. L’analyse des pratiques en cours permet de repérer certaines conditions pour favoriser la participation des personnes concernées dans les formations en travail social. La première consiste, en préalable, à s’appuyer sur un réel partenariat avec des collectifs de personnes concernées.

Ce cours a été conçu puis délivré avec et par des duos d’intervenants comprenant des porteurs d’une déficience intellectuelle. Une formation de formateurs a été réalisée lors des douze mois précédant les 18 heures de cours qui ont ensuite été délivrées. Chacun des duos a ainsi participé à la définition des objectifs et scénarios pédagogiques, a animé son cours, évalué les étudiants puis évalué la formation elle-même. Nous présentons les détails de la formation, puis brièvement ses retours d’expérience et la mise en place d’un certificat universitaire dans le prolongement du projet.
Detection of Subclinical Corneal Ectasia Using Corneal Tomographic and Biomechanical Assessments in a Japanese Population
Authors: Koh Shizuka , Ambrósio Renato , Inoue Ryota , Maeda Naoyuki , Miki Atsuya , Nishida Kohji
Published: June 2019

PURPOSE:

To test the detection of subclinical corneal ectasia using integrated Scheimpflug tomography and biomechanical assessment in a Japanese population.

METHODS:

This prospective, case–control study included 23 patients with very asymmetric ectasia (VAE) and 70 normal controls. Patients with VAE had defined clinical ectasia in one eye and a fellow eye with normal topography (VAE-NT). Objective topography for confirming normal topography in VAE-NT cases included having 0% similarity and 0% severity derived from Placido-disk based topography. Scheimpflug-based corneal tomography and corneal biomechanical assessment were performed. The Belin/Ambrósio Enhanced Ectasia Deviation index (BAD-D), Corvis Biomechanical Index (CBI), and Tomographic Biomechanical Index (TBI) were compared and their discriminating ability for detecting ectasia was assessed.

RESULTS:

For differentiating normal and VAE-NT eyes, the areas under the receiver operating curve for the BAD-D, CBI, and TBI were 0.668, 0.660, and 0.751, respectively. The TBI cut-off of 0.259 provided 52.17% sensitivity and 88.57% specificity. Fourteen VAE-NT cases (60.9%) were abnormal in at least one of the criteria of the BAD-D > 1.60 (39.1%), CBI > 0.5 (26.1%), or TBI > 0.29 (43.5%). Conversely, nine VAE-NT cases (39.1%) exhibited normal values for the BAD-D, CBI, and TBI.

CONCLUSIONS:

In the current study, 40% of VAE-NT eyes were classified as normal by the BAD-D, CBI, and TBI. Although some of these cases may truly represent unilateral ectasia, further advances are needed to enhance ectasia detection and characterize the susceptibility for ectasia progression.

Integrative Approach to Pediatric Nausea
Authors: Arruda Jenna , Yeh Ann Ming
Published: June 2019

Nausea is a bothersome symptom that is commonly seen in the pediatric population. The pathophysiology of nausea is complex and involves the central nervous system, the enteric nervous system, gastrointestinal tract motility, and psychologic influences. Pharmacologic and nonpharmacologic therapies are available for treating nausea. Mind-body interventions (hypnosis, biofeedback), botanicals and supplements (ginger, enteric-coated peppermint oil), aromatherapy, and acupuncture have emerging evidence for effectively treating pediatric nausea.

Executive Functioning and Problem Solving: A Bidirectional Relation
Authors: Drigas Athanasios , Karyotaki Maria
Published: June 2019

There is a bidirectional relation between one’s executive functioning abilities and problem solving skills as they are both based on self-control. “Hot” and “cold” executive functions account for individuals’ cognitive control and emotional regulation. In addition, problem solving is tied to metacognitive awareness processes, necessary for applying executive function skills in goal setting and decision making situations. Therefore, individuals’ overall cognitive flexibility and emotional regulation can promote the quality, quantity and speed of decision-making processes, such as adaptable and creative information processing as well as efficiency in setting and prioritizing goals. Moreover, individuals with ADHD, Autism Spectrum Disorder, Oppositional Defiant Disorder and individuals with other comorbid states, such as older adults, individuals with Traumatic Brain Injury (TBI) can counterbalance their cognitive control deficits through enhancing their problem solving skills. In addition, an advanced research in the bidirectional relation between executive function and problem solving skills could develop a comprehensive methodology for training and assessing self-regulatory processes.
Continuous Use Intention of E-Government Portals the Perspective of Older Citizens
Authors: Yap Ching Seng , Ahmad Rizal , Newaz Farhana Tahmida , Mason Cordelia
Published: June 2019

This study aims to examine the effect of perceived value, perceived behavioural control and social influence on older citizens' attitude toward e-government portals and their continuous use intention. Through a questionnaire survey, primary data are collected from 123 older citizens aged 50 and above who use e-government portals. The findings show that older citizens generally have positive attitude toward e-government portals and are favourable on their continuous use intention. Older citizens rate cost, convenience, and information accuracy as the most important dimensions of perception of value of e-government portals. All the three determinants of older citizens' attitude toward e-government portals are positive and statistically significant, with perceived behavioural control having the strongest effect on attitude, followed by perceived value and social influence. Older citizens' attitude also positively and strongly relates to their continuous use intention of e-government portals.
Exploring the Moderating Effect of Perceived Usefulness on the Adoption of E-Government Services
Authors: Mensah Isaac Kofi
Published: June 2019

This study explored the moderating effect of perceived usefulness on the impact of trust in the internet and trust in government on the intention to adopt e-government services. The Technology Acceptance Model (TAM) was used as the theoretical foundation for this study. The results indicated that trust in the internet and trust in government were both significant predictors of the intention to use e-government services. It was also discovered that trust in the internet was a positive determinant of trust in government. Furthermore, the study revealed that while perceived usefulness had a significant moderating effect on the impact of trust in the internet on the intention to use e-government services, it was however not significant in moderating the impact of trust in government on the intention to use. The significant and non-significant moderating effect of perceived usefulness on both the relationship between trust in the internet and trust in government on the intention to use is the unique contribution of this study. The implications of these findings are discussed.
E-Government as a Tool for Improving Entrepreneurship
Authors: Abu-Shanab Emad Ahmed , Osmani Mohamad
Published: June 2019

This article addresses the relationship between e-government development and entrepreneurship. The study adopted an inductive approach, where it utilized archival data to test the relationship between the two paradigms. The authors hypothesize that improving e-government initiatives will influence entrepreneurship. Utilizing global data will guard for researcher biases and utilize the huge sample size built in the archival data used. The two data sets included the UN's e-government survey, and the Global Entrepreneurship and Development Institute survey. Results indicated a full support of the relationships assumed between the major dimensions of EGDI and GEI. Regression analysis indicated that Online service Index and telecommunication Infrastructure index are significant predictors of GEI, but failed to support the role of Human Capital Index. The coefficient of determination of the regression equation estimated 69.2% of the variance in GEI. Further tests and research conclusions are stated at the end.
“ICT Is for Boys”

There is worldwide consensus on how important women are for development where gender equality is seen as a prerequisite for sustainable development. Information and communication technologies (ICTs) are seen as one of the most promising tools for the empowerment of women in developing countries. Men and women therefore need to have equal opportunities to access and use ICTs. Here, the authors, however, find a huge gender gap, and the reasons for this gap are still not fully understood or investigated. The purpose of this study is therefore to further investigate the reasons for this gap in ICT use. Based on a review of existing literature, as well as interviews with men and women from developing countries, the main finding is that the impeding factor underlying all barriers described in the literature relates to social norms. Based on this insight, the authors end the paper by discussing implications for research and practice.
Two Routes to Trust Calibration
Authors: Kraus Johannes Maria , Forster Yannick , Hergeth Sebastian , Baumann Martin
Published: June 2019

Trust calibration takes place prior to and during system interaction along the available information. In an online study N = 519 participants were introduced to a conditionally automated driving (CAD) system and received different a priori information about the automation's reliability (low vs high) and brand of the CAD system (below average vs average vs above average reputation). Trust was measured three times during the study. Additionally, need for cognition (NFC) and other personality traits were assessed. Both heuristic brand information and reliability information influenced trust in automation. In line with the Elaboration Likelihood Model (ELM), participants with high NFC relied on the reliability information more than those with lower NFC. In terms of personality traits, materialism, the regulatory focus and the perfect automation scheme predicted trust in automation. These findings show that a priori information can influence a driver's trust in CAD and that such information is interpreted individually.
Theoretical Investigation of NiI2 Based Bilayer Heterostructures

Published: June 2019

The electronic structure of nickel iodide monolayer in NiI2/ScX2 (X = S, Se and Te) and NiI2/NiTe2 heterostructures was investigated by density functional theory (DFT). The spin-asymmetric semiconducting behavior of NiI2 monolayer in these interfaces was observed. The width of the band gap of the NiI2 monolayer practically does not change in heterostructures and remains at the level of 1.7 and 3.0 eV for minor and major spin channels, respectively. The NiI2 layer can be p-doped by stacking with ScX2 dichalcogenides. On the contrary, charge transfer (~0.01 |e| per f.u.) from NiTe2 leads to n-doping of NiI2. As a result, the Fermi level shifts up to the area of NiI2 conduction band with spin down carriers only, which gives prospects of using this material in spin filter applications. The electronic structure of NiI2/ScTe2 under isotropic deformation in the plane remains the same under tension and compression within 5%, except for a small change in the band gap in the composite layers of NiI2 within 25%. This allows one to conclude about the stability of the electronic properties under deformations, which gives possibility to use the heterostructures in flexible electronics devices.

The hydrolytic lignin (HL) derivatives have been prepared via its physical activation (high-temperature annealing in vacuum) followed by chemical modification (fluorination). It was found that the graphitized product of thermal activation up to 1000 °C at a low temperature gain rate of < 2 °C/min under high vacuum shows an enhanced specific surface area (215 m2/g), that makes it potentially useful as sorbent, catalytic substrate, or electrode material. It was revealed from the experimental data the manufactured graphitized material consists of nanometric structural blocks, possibly nanographites and/or few-layer nanographenes. The edges of graphenes in agglomerates in activated hydrolytic lignin (AHL) have armchair and zigzag shapes. The nontrivial electronic structure of the zigzag edges, along with the electronic conductivity and the ability of AHL to absorb oxygen, can cause an increase in the energy intensity of lithium battery (LB) manufactured using AHL.The carbon-fluorine bond of semi-ionic type was detected in HL and AHL fluorinated in the temperature range of synthesize 60 – 300 oC. The fluorinated forms of both HL and its thermally activated product show increased values of operating voltage due to the participation of fluorine bound to carbon in the electrochemical process.

Published: June 2019

Using the methods of spectral analysis with application of the formalism of the integral function of Lebesgue measures and Kullback's divergence, the structural features of the interfaces of spinning Fe- (Cu, Nb) - (Si, B) tapes with different metalloid contents are investigated. An increase in the total concentration of the metalloid ambiguously affects the nature of the morphology of rapidly quenched alloys. The minimum difference in the statistics of contact and free surfaces, formed in the spinning process, is demonstrated by fusionFe74Cu1Nb3Si16B6.
Strength Determination Based on the Results of Modeling the Crack Propagation in a Nanostructured Hard Alloy
Authors: Dvornik Maksim , Mikhailenko Elena
Published: June 2019

The process of crack propagation from the initial pore in the microstructures of WC-Co alloys with different volume fraction of the cobalt phase was studied by simulation of the stressed state by the finite element method. A calculation of the energy release rate during the propagation of crack through sections which consist of the carbide grains and the cobalt phase was made. It is shown that the strain energy release rate increases with crack propagation in WC grains and decreases with crack propagation in the intermediate layers of cobalt. The maximum stresses required for the destruction of the cobalt layer determine the strength of the entire microstructure. The strength of the alloy increases when decreasing pore diameter and increasing the cobalt phase fraction.

Published: June 2019

Sn-containing oxide coatings were prepared via plasma electrolytic oxidation (PEO) of Ti plate in the electrolytes with [SnII-EDTA]2- complex anions or SnO2 particles in the anode and anodic-cathodic modes. The coatings formed in electrolyte with SnO2 particles stabilized by SAS contain SnO2 and Sn0. In the electrolyte with [Sn-EDTA]2- complex anions, the SnO2-containing coatings were formed in the anodic mode while Sn0-containing ones were obtained in the anodic-cathodic mode. SnO2-containing structures formed in the electrolytes with [Sn-EDTA]2- anions are shown to be active in catalytic oxidation of CO into CO2 at temperatures above 350 °C. They can be the basis for the preparation of both carriers of catalytically active compounds and catalysts for redox reactions. Potentiometric tests showed that the Sn-containing PEO layers on titanium exhibit the most characteristic pH function for the metal oxide electrodes in the direct potentiometry and acid-base titration.

Mucosal-associated invariant T (MAIT) cells and invariant NK T (iNKT) cells account for the major lymphocyte populations that express invariant TCRα-chains. MAIT cells mostly express the TCRVα19-Jα33 TCR in mice and the TCRVα7.2-Jα33 TCR in humans, whereas iNKT cells express the TCRVα14-Jα18 TCR in mice and the TCRVα24-Jα18 TCR in humans. Both MAIT and iNKT cells have the capacity to quickly produce a variety of cytokines in response to agonist stimuli and to regulate both innate and adaptive immunity. The germline TCRJα18 knockout (Traj18−/−) mice have been used extensively for studying iNKT cells. Although it has been reported that the TCRα repertoire was narrowed and the level of Trav19-ja33 transcript was decreased in this strain of mice, direct assessment of MAIT cells in these mice has not been reported. We demonstrate in this study that this strain of mice is also defective of MAIT T cells, cautioning data interpretation when using this strain of mice.
