Activities - Enormous Importance in the Modern English
Authors: Gari Bhargavi Pedda Ramireddy
Published: September 2020

This paper aims to explore the importance and effectiveness of activities when they are used in EFL or ESL classrooms. And concentrating how activities are useful for the Primary and Secondary school students. These young learners are not in a matured time of their learning and cannot all find out the importance foreign language learning. But teachers and parents should make them understand and lead them towards language acquisition without fail. So, activities are the most discussable thing in joyful learning. Activities play a vital role in second language learning in terms of providing a stress free atmosphere for EFL learners in which there are fun, motivation, interest, curiosity to enhance their language learning.
Jurgen Moltmann’s Theology of Hope and the Task of Public Theology in Ghanaian Context
Authors: Appiah-Kubi Francis , Osei Karikari Isaac
Published: September 2020

This article examines the relevance of theology in public life particularly from the Ghanaian (African) Christian experience in society. The idea of the public relevance of theology has been ably examined by Jurgen Moltmann in the perspectives of his Theology of Hope and the continuous reflections in the “Ethics of Hope”. The eschatological sacrifice of Christ’s story animates in Moltmann the understanding of what particular transformation one must experience when envisaging what the shape of Christianity is in modern society and the task it has to fulfill in the field of social ethics in the Ghanaian social and political history. Critical to the Ghanaian social- political life is to be encountered with is a sub-culture trend that the task for the socio-political and the economic development of the nation-state is the preserve of politics or political activists. The conversation on the rise to action of the Ghanaian Christian to social ethics is now due to the growing trends of poverty, violence, unemployment, corruption, dwindling social and moral order and failing institutions of state. Jurgen Moltmann develops his thoughts in the Ethics of Hope to deliberately project Christian social ethics that is focused on projecting the Bible as the gospel of hope for the people. This paper evaluates Moltmann’s understanding of modern realities of life and how Christians must relate with and what Christian character brings to bear on the positive change in the life of the people.
THE NEXUS OF GOVERNMENT INCENTIVES AND SUSTAINABLE DEVELOPMENT GOALS: IS THE MANAGEMENT OF RESOURCES THE SOLUTION TO NON-PROFIT ORGANISATIONS?
Authors: Anwar Muhammad , Khattak Muhammad Sualeh , Popp József , Meyer Daniel Francois , Máté Domicián
Published: September 2020

Sustainable Development Goals (SDGs) have become the main priority across the globe due to their significant role in economic growth
and propensity. However, in particular, it is not yet known how governments can achieve SDGs through non-profit organisations (NPOs) by providing financial
and non-financial incentives. The present study included 263 Pakistan NPOs in a primary survey using a questionnaire. The results obtained from the Structural
Equation Modelling (SEM) highlight that: (i) government incentives do not directly influence community development; (ii) The government non-financial
incentives have a significant direct effect on environmental activities to reduce pollution, energy consumption and waste; (iii) Resource management fully
mediates the paths between government incentives and community development while partially mediates environmental activities; and finally, (iv) resource
management has a favourable influence both on the goals of community development and environmental activities. This research paper contributes to the knowledge
in that government incentives do not have a direct influence on social development, but has an indirect influence through efficient management. Recommendations
are that government and public bodies need to support NPOs to engage actively in philanthropic activities. Similarly, NPOs should efficiently utilize and manage
the resources to benefit the maximum number of poor and needy individuals.
Evidence for Dense Gas Heated by the Explosion in Orion KL

Published: September 2020

We mapped the kinetic temperature structure of Orion KL in a ∼20″ (∼8000 au) sized region with para-H2CS 707 − 606, 726 − 625, and 725 − 624 making use of Atacama Large Millimeter/submillimeter Array Band 6 Science Verification data. The kinetic temperatures obtained with a resolution of 1.″65 × 1.″14 (∼550 au) are deduced by modeling the measured averaged velocity-integrated intensity ratios of para-H2CS 726 − 625/707 − 606 and 725 − 624/707 − 606 with a RADEX non-LTE model. The kinetic temperatures of the dense gas, derived from the para-H2CS line ratios at a spatial density of 107 cm−3, are high, ranging from 43 to >500 K with an unweighted average of ∼170 K. There is no evidence for internal sources playing an important role in the heating of the various structures identified in previous work, namely the elongated ridge, the northwestern clump, and the eastern region of the compact ridge, while the high temperatures in the western region of the compact ridge may be dominated by internal massive star formation. Significant gradients of kinetic temperature along molecular filaments traced by H2CS indicate that the dense gas is heated by the shocks induced by the enigmatic explosive event which occurred several hundred years ago and greatly affected the energetics of the Orion KL region. Thus, with the notable exception of the western region of the compact ridge, the high temperatures of the dense gas in Orion KL are probably caused by shocks from the explosive event, leading to a dominant component of externally heated dense gas.
Can Chondrules Be Produced by the Interaction of Jupiter with the Protosolar Disk?
Authors: Bodénan Jean-David , Surville Clément , Szulágyi Judit , Mayer Lucio , Schönbächler Maria
Published: September 2020

Chondrules are crystallized droplets of silicate melt formed by rapid heating to high temperatures (>1800 K) of solid precursors followed by hours or days of cooling. The time interval of chondrule formation is consistent with the formation timescale of Jupiter in the core-accretion model (1–4 Myr). Here we investigate if the shocks generated by a massive planet could generate flash heating episodes necessary to form chondrules using high-resolution 2D simulations with the multifluid code RoSSBi. We use different radiative cooling prescriptions, planet masses, orbits, and disk models. Temperatures reached during flash heating can be deduced from chondrule observations and are achieved in a Minimum Mass Solar Nebula (MMSN) for a massive protoplanet (>0.75 M
♃) but only in cases in which radiative cooling is low enough to lead to nearly adiabatic conditions. More realistic thermodynamics undershoot the temperatures required in shocks for chondrule formation. However, these temperatures are reached when considering more massive disks (e.g., five MMSN), but these conditions lead to fast planet migration and too low cooling rates compared to those deduced from chondrule textures. Thus, it seems unlikely that shocks from Jupiter can form chondrules in most cases. Independent of the nebular mass, the simulations demonstrate that a massive planet that forms a gap triggers vortices, which act as dust traps for chondrule precursors. These vortices also provide a high-pressure environment consistent with cosmochemical evidence from chondrules. They only lack the flash heating source for a potential chondrule formation environment.
Evolution of Dust and Water Ice in Cometary Comae by Radiative Torques
Authors: Hoang Thiem , Tung Ngo-Duy
Published: September 2020

Comets provide unique information about the physical and chemical properties of the environment in which the solar system was formed. Understanding how cometary dust and ice evolve under the effect of sunlight is essential for constraining nuclear structure and triggering the mechanism of comet activity. In this paper, we first study the rotational disruption of dust grains lifted by outgassing from comet nuclei by radiative torques (RATs). We find that composite grains could be rapidly disrupted into small fragments by the RAT disruption mechanism. We then study rotational desorption of ice grains by RATs and find that icy grains could be desorbed from large heliocentric distances, beyond the sublimation radius of water at

. We also calculate the production rate of water vapor versus the heliocentric distance of comets due to rotational desorption. Our results could explain the variation of dust properties and the presence of small grains frequently observed from cometary comae. Finally, we suggest that the activity of distant comets could be triggered by rotational disruption of grains and desorption of water-ice grains at large heliocentric distances.
Galaxies in the Zone of Avoidance with the Spitzer Space Telescope

Published: September 2020

In this work we describe 59 galaxies discovered in the talk-forum of the Milky Way Project (MWP) by volunteers of the project. The MWP is based on infrared images by the Spitzer Space Telescope and primarily probes the Zone of Avoidance for star-forming regions located in the Milky Way. The list of galaxies found here include 35 galaxies previously not described, a possible galaxy cluster and two galaxies that could be located in the Great Attractor Wall. The volunteers mainly discovered larger (d > 12″) galaxies with a higher star-forming rate and likely missed galaxies with low star-forming rate or small galaxies. This work demonstrates that many galaxies in the Zone of Avoidance remain undiscovered in the GLIMPSE data set.

Le capital déteste tout le monde
Authors: Dieuaide Patrick , Dessendier Emmanuel
Published: September 2020

Que peuvent espérer aujourd’hui les écologistes face au néolibéralisme ? Si l’ouvrage de Maurizio Lazzaratto 1 ne répond pas ouvertement à la question, après sa lecture, on imagine mal que le capitalisme se laisse convaincre de la légitimité des combats écologistes qui sont menés de front en défense de la Terre et de nos vies, et fasse une exception à son arrogance. Pour l’auteur, le capitalisme n’est pas le moins mauvais des systèmes économiques et politiques, qui laisserait ouvert le champ des possibles. Il est une « machine de guerre » fascisante qui soumet et dépolitise les populations. À l’ère de l’Anthropocène, voilà qui devrait interroger les écologistes du monde entier sur l’urgence d’une stratégie et d’une alternative politique qui puisse faire face au réel. Le temps des ruptures serait-il venu pour l’écologie politique ?
Les besoins en logement et leur géographie
Authors: Dumont Gérard-François
Published: September 2020

Rappelant combien le logement répond à un besoin essentiel, cette analyse détaille d’abord les paramètres dont dépend l’évolution du nombre de ménages et de logements. Puis elle présente dans une deuxième partie les grandes tendances pour les prochaines années en France. En dépit de l’inertie des mouvements démographiques, les projections à l’échelle nationale demeurent incertaines. C’est encore plus le cas à l’échelle locale où, comme cela est expliqué dans la troisième partie de ce texte, des paramètres spatiaux et réglementaires compliquent encore plus l’exercice prospectif. Toutefois, si elle n’est pas une science exacte, la prospective demeure une démarche féconde : elle est en effet un puissant vecteur d’échanges argumentés et critiques entre citoyens usagers, experts et décideurs, qui permet une meilleure compréhension des besoins en logement. Elle peut donc être d’une aide précieuse à la décision et à l’action des acteurs publics et privés du logement.
À hauteur d’enfant
Authors: Pignot Manon
Published: September 2020

Cet article revient sur la constitution progressive des enfants en tant qu’objet d’Histoire reconnu, et montre combien l’étude des expériences de guerre enfantines y a contribué. Le changement de regard historien s’est accompagné d’un important renouvellement archivistique, pour lequel l’apport des sciences de la psyché fut fondamental : dessins, productions enfantines, témoignages personnels sont autant de sources dont la prise en considération va de pair avec la reconnaissance, pour les enfants, de leur statut d’acteurs à part entière du phénomène guerrier.
L’enfant Mort. L’enfant Vie
Authors: Lachal Christian
Published: September 2020

Pris dans les guerres depuis toujours, les enfants y occupent des rôles divers, selon les circonstances. Quelle que soit leur place, ils sont marqués par l’éventualité de leur mort, et l’enfant mort fascine et afflige en même temps. Les différentes représentations, collectives ou individuelles, de l’enfant-mort nous renvoient à notre ambivalence et à l’énigme de l’émergence de la vie. Comment l’enfant peut-il conserver et retrouver en lui cette possibilité de vie ? L’auteur explore l’évolution chronologique de l’enfant, de la guerre à l’exil, de l’exil au camp de réfugiés. Les enfants réfugiés sont donc, aujourd’hui, considérés comme des survivants. Comment les aider à construire leur futur ? La tendance actuelle des associations humanitaires est de s’appuyer sur les capacités d’imagination, de rêverie, de communication et de créativité des enfants. Un exemple est proposé, à partir des données de terrains évalués par l’auteur dans les camps de réfugiés congolais au Burundi et des réfugiés syriens en Jordanie et au Liban.
Chine : la Longue Marche vers la transition énergétique
Authors: Guilhot Laëtitia , Meunié André , Pouyanne Guillaume
Published: September 2020

Cette étude analyse l’évolution des dynamiques structurelles sous-tendant les émissions de CO 2  en Chine sur la période 1981-2015. Les progrès en efficacité énergétique sont le principal facteur qui a limité la puissance de l’effet d’échelle lié à la croissance économique. Entre 1981 et 2000, ils sont le fruit de la modernisation des équipements. À partir de 2001, de mauvaises performances énergétiques vont pousser les autorités centrales à adopter des politiques volontaristes, permettant une évolution du mix énergétique en faveur des énergies renouvelables. Cette tendance, couplée à la poursuite de l’efficacité énergétique, ont permis à la Chine, depuis 2011, d’engager un processus de transition énergétique.
La lutte contre le changement climatique et la transition énergétique chinoise
Authors: Maréchal Jean-Paul
Published: September 2020

Depuis quelques années, la position de Pékin dans les négociations climatiques internationales a radicalement changé. Longtemps rétive à tout engagement internationale, la Chine se présente désormais comme garante de l’application de l’Accord de Paris, dont elle a d’ailleurs permis l’adoption. L’objet de cet article est d’analyser dans une optique d’économie politique internationale en quoi cette nouvelle attitude a partie liée avec la transition énergétique chinoise.
La monnaie locale écologique, une tentative d’évaluation
Authors: Mathieu Alban
Published: September 2020

L’article cherche à évaluer la proposition monétaire effectuée par Blanc et Fabert (2017) pour financer la transition écologique. Il dresse une comparaison avec la monnaie fiscale complémentaire en s’appuyant sur le concept de monnaie publique. L’étude montre que la monnaie locale écologique dispose d’une organisation institutionnelle pertinente pour assurer sa circulation et d’une plus grande légitimité politique. Paradoxalement, les limites inhérentes à cette monnaie sont les raisons de sa réussite. En ne cherchant pas à affecter les grands agrégats monétaires, la création monétaire peut être maîtrisée en fonction des besoins et des conditions économiques et fiscales du territoire.
Le rite hallucinogène comme technique du Soi : une approche anthropologique de l’efficacité des psychédéliques dans le traitement des addictions
Authors: Dupuis David
Published: September 2020

Bien que les substances dites « hallucinogènes » ou « psychédéliques » telles que l’ayahuasca connaissent depuis peu un regain d’intérêt pour leurs propriétés thérapeutiques, notamment dans le champ de la santé mentale, les ressorts de leur efficacité restent mal connus. En s’appuyant sur les données recueillies au cours d’une enquête ethnographique menée dans une clinique d’Amazonie péruvienne, cet article propose d’explorer les ressorts de l’efficacité de l’ayahuasca dans le traitement des addictions. Mobilisant une approche anthropologique dialoguant avec la théorie des systèmes, l’auteur montre que l’efficacité thérapeutique de l’ayahuasca repose sur l’élaboration de relations avec des êtres non humains habituellement invisibles, qui conditionne pour le sujet de profondes reconfigurations identitaires. Le rite hallucinogène, décrit en ce sens comme une pratique « spirituelle » par les usagers, apparaît ainsi comme une « technique du Soi » conduisant les participants à réinterpréter leur biographie et leurs comportements quotidiens à l’aune d’un nouveau modèle culturel. La transformation de l’identité et de la théorie du Soi conditionnée par cette dynamique de reconfiguration narrative ainsi que ses implications comportementales et cognitives apparaissent alors comme les principaux catalyseurs de la cure. L’approche anthropologique proposée invite à repenser la toxicomanie et l’efficacité thérapeutique des psychédéliques au-delà des modèles neuropharmacologiques et psychodynamiques, pour mieux prendre en compte les processus identitaires, narratifs et sociaux dans la compréhension des comportements addictifs ainsi que la dimension « spirituelle » de ces pratiques, dont l’importance est soulignée par les usagers.
Spiritualité et psychotropes : groupe d’entraide en 12 étapes et Santo Daime, essai de comparaison
Authors: Granier Jean-Maxence
Published: September 2020

Cet article met en regard deux approches apparemment aux antipodes l’une de l’autre : d’un côté, les groupes d’entraide par l’abstinence et de l’autre, le néo-chamanisme du Santo Daime. Pourtant, des points communs existent entre ces deux « communautés ». Nous verrons comment s’articulent psychotropes et spiritualités et montrerons quelles pistes de réflexion ce parallèle nous inspire : renforcer le rôle de la spiritualité en regard de l’addiction comme aliénation et réinscrire les usages de psychotropes dans des formes sacrées et ritualisées.
Qigong : globalisation versus métabolisation
Authors: Plet Nathalie
Published: September 2020

Le qigong 氣功 , traduit littéralement par « travail du souffle », est entré dans le champ de la recherche médicale en France depuis 2010 sous la dénomination MAC, Médecine Alternative Complémentaire, terme adopté par l’Organisation Mondiale de la Santé (OMS). Cet article s’intéresse à l’actuel mouvement d’institutionnalisation de cette technique du corps chinoise ancestrale dans notre système de soin par le détour nécessaire de la recherche. Nous assistons à une convergence de forces : celles dérivées des directives internationales en faveur d’une médecine intégrative, de l’intérêt de nos contemporains pour une vision holistique et des chercheurs à en comprendre les mécanismes d’action pour en valider la contribution scientifique, notamment dans le champ des addictions. Un compromis semble possible entre verticalité, celle exercée par les instances internationales et horizontalité, soit la demande de nos contemporains, notamment dans le traitement de la douleur chronique. Le choix d’une méthodologie mixte, biomédicale et psychologique orientée à la psychanalyse, permet d’investiguer les contributions du qigong dans sa fonction d’auto-étayage, de donner la parole aux patients, de laisser place au vécu subjectif et non de réduire les acteurs à une appréhension formelle de la psychopathologie. L’intérêt du PHRC est très important puisqu’il permet de recueillir des éléments cliniques et de mesurer l’efficacité d’une technique pour laquelle il existe peu de données à ce jour.
Le signifiant : prudence de Lévi-Strauss ou audace de Lacan ?
Authors: Huang Zuo
Published: September 2020

Lacan n’est pas le seul responsable d’une révolution théorique renversant l’« algorithme » saussurien pour donner au signifiant la primauté sur le signifié. Il exprimait clairement sa dette théorique envers Lévi-Strauss. Mais l’initiative de l’idée lévi-straussienne a sa propre origine. Saussure et la phonologie structuraliste n’en sont pas la seule source. C’est sous l’influence de l’anthropologue Franz Boas que Lévi-Strauss trouve d’abord que les lois du langage fonctionnent au niveau inconscient en dehors du contrôle des sujets parlants. Mais ce n’est qu’avec Lacan que la question de l’inconscient structural est explicitement posée et l’idée de la primauté du signifiant démontrée par là. Il est regrettable que Lévi-Strauss ait alors abandonné l’initiative de l’idée et c’est Lacan qui en discerne le précieux trésor.
Sensory Strabismus-Eso or Exo?
Authors: Havertape Susan A , Cruz Oscar A , Chu Fred C
Published: September 2020

ABSTRACT

Purpose: The type of horizontal strabismus from loss or impairment of vision is thought to depend on patient age at the time of vision loss. Association between the age at onset of vision loss and development of esotropia vs exotropia will be determined.

Methods: Patients with a diagnosis of sensory strabismus and visual acuity of 20/40 or poorer were reviewed as well as patients with diagnoses consistent with the development of sensory strabismus. Parameters considered were age at onset of vision loss and type of strabismus. Patients were excluded if the age at onset was not clear.

Results: Of 123 patients with sensory strabismus reviewed: 82 (67%) had unilateral vision loss; 41 (33%) had bilateral vision loss; 75 (61%) had congenital vision loss; 50 (67%) developed esotropia; 25 (33%) developed exotropia; 48 (39%) had acquired vision loss; 5 (10%) developed esotropia; and 43 (90%) developed exotropia. A significant difference was noted between age at onset and type of horizontal strabismus (X
p 2
= 37.44; P <.0001).

Conclusion: Of patients with congenital vision loss, 67% developed sensory esotropia and 33% developed sensory exotropia. Of those with acquired vision loss, 10% developed sensory esotropia and 90% developed sensory exotropia. Patients with congenital vision loss are significantly more likely to develop esotropia, P <.005, and those with acquired vision loss are significantly more likely to develop exotropia, P <.001.

Dependencia y pasividad en la selección de fuentes informativas en el periodismo radiofónico en España
Authors: Fernández-Sande Manuel , Chagas Luãn , Kischinhevsky Marcelo
Published: September 2020

El artículo es el resultado de un estudio exploratorio que analiza los procesos de selección de las fuentes informativas en la producción de noticias por parte de los periodistas radiofónicos. El corpus de análisis está integrado por las noticias difundidas en los programas informativos de mediodía de las cuatro grandes cadenas españolas de ámbito estatal (Cadena SER, Cadena COPE, Onda Cero y Radio Nacional de España) durante cuatro semanas de programación. A partir de una propuesta propia de taxonomía de las fuentes periodísticas, se ha aplicado el análisis de contenido con el objetivo de conocer cómo son utilizadas estas fuentes en la construcción de las noticias y establecer posibles diferencias entre las principales secciones temáticas. Los resultados muestran una elevada dependencia respecto a las fuentes oficiales y una importante pasividad en el proceso de selección de fuentes, lo que contrasta con valores característicos presentes en el discurso teórico de la práctica profesional.
La “infodemia” en la crisis del coronavirus: Análisis de desinformaciones en España y Latinoamérica
Authors: López-Pujalte Cristina , Nuño-Moral María Victoria
Published: September 2020

En este trabajo se analizan las desinformaciones difundidas sobre el coronavirus en España y Latinoamérica en el periodo comprendido entre el 23/01/2020 y el 03/05/2020; se estudian cuantitativamente los siguientes datos: volumen de desinformación por país, la línea de evolución temporal, tipo de desinformación, canal de difusión, las fuentes, y redes de circulación de bulos entre distintos países. En el caso de España, se examina también la correlación en la producción de desinformaciones con la evolución de la pandemia, y las tendencias de búsquedas en internet sobre el coronavirus.
Los resultados muestran claramente que la evolución de la pandemia influye en la propagación de los bulos, disparándose estos en momentos críticos como la declaración de pandemia por parte de la OMS y, en el caso de España, en los momentos de mayor tasa de crecimiento de la curva, al tiempo que las búsquedas sobre el tema alcanzan su máxima popularidad.
Accuracy Improvement of RSSI-based Distance Localization using Unscented Kalman Filter (UKF) Algorithm for Wi-Fi Tracking Application
Authors: Fuada Syifaul , Adiono Trio , Prasetiyo Prasetiyo
Published: September 2020

In this report, we perform the digital filter computation using Matlab for Wi-Fi tracking application. This work motivates to improve the accuracy of filter algorithm in the RSSI-based distance localization system. There are several aspects that we can improve, e.g., in the Filter part and Path-loss model. But, in this work, we focus on filter part; Unscented Kalman Filter (UKF) is implemented to replace linear Kalman Filter (KF), which is used in previous work. Based on the performance comparison, UKF has 90% hit ratio while linear KF has only 81.15 % hit ratio. We found that UKF can handle the noise in RSSI. Further work, the UKF algorithm is then embedded on the server system.
Learning Management Strategy of Communication Studies through Blended Learning in Higher Education
Authors: Putri K. Y. S. , Abdullah Zulhamri Bin , Nugrahaeni Elisabeth , Darmawan Rachmat , Latifa Latifa
Published: September 2020

This study aims to identify learning management strategies on communication studies through Blended Learning in Higher Education. This study uses a quasi-experimental method with a non-equivalent control group research design. This design uses two groups, namely the experimental group and the control group. Data collection was conducted with 82 Communication Studies students in 2019, Faculty of Social Sciences, Jakarta State University. Researchers also work with ethics communication lecturers and new media lecturers. The results of this study indicate that blended learning can increase students' knowledge of ethical communication. The average pretest value of the experimental class was 55.93, and the posttest value was 81.85. The average N-Gain in both the experimental class and the control class falls into the medium category. The average results of the N-Gain experimental class were higher at 0.56 compared to the control class at 0.36. Student learning attitudes in handling hoaxes get an average value of 2.99 while the control class is only 2.61. Although both of them have proper criteria, blended learning can also encourage participants to make the best use of face-to-face contact in developing knowledge. Thus, students are able to identify hoax news and implement it by providing information through social media to the public. The implications of this study provide convenience for lecturers in conducting learning strategies on learning ethical communication and new media for handling hoaxes.

CSR in the Spotlight
Authors: Claver-Cortés Enrique , Marco-Lajara Bartolomé , Poveda-Pareja Esther
Published: September 2020

This study has as its aim to analyze the existence of a possible theoretical relationship between corporate social responsibility (CSR) development and two factors, namely business location and managers' gender. The industrial district (ID) theory serves as the basis to demonstrate the possible influence of location on this type of environment with an improved implementation of social practices. At the same time, the authors will also consider the possible influence of internationalization within the cluster on CSR development since globalization itself can further favor the implementation of CSR practices. The study additionally examines the role that the variable ‘directors' gender', and more precisely, women directors, can play as a key factor in the development of such practices. The implications that the concurrence of these factors might have, along with the future lines of research that would derive therefrom, will finally be considered.
University Social Responsibility

Published: September 2020

This chapter highlights the role of technology-based universities in public-private partnerships (PPP) to strengthen and deploy the digital single market strategy. Moreover, it analyzes how these collaboration channels have link knowledge management as a tool for sustainable collaboration. Given the need to establish collaboration channels with the private sector, according to Lee, it is critical to establish the impact of sharing sophisticated knowledge and partnering at the same time. This chapter wants to highlights two relevant aspects of PPP: on the one hand, the importance of integrating the participation of a technology-based university with three objectives: (1) the coordination, (2) the funding management, and (3) the dissemination of results; and the other hand, the participation private sector that is represented by agile agents capable to execute high-value actions for society. With the recognition of these values, the investment and interest of the projects under way are justified by public-private partnership.
Influência das prioridades estratégicas na adoção de ferramentas de controle gerencial e no desempenho: um estudo empírico em empresas industriais paranaenses
Authors: Panosso Alceu , Camacho Reinaldo Rodrigues , Espejo Márcia Maria dos Santos Bortolocci , Abbas Katia
Published: September 2020

O objetivo deste estudo é investigar a influência das prioridades estratégicas na adoção de ferramentas de controle gerencial e no desempenho de empresas industriais paranaenses. Como suporte à análise dos dados foi desenvolvida uma revisão de literatura versando sobre prioridades estratégicas, essencialmente consubstanciadas em Porter (1989), estudos sobre estratégia organizacional e ferramentas de controle gerencial. Para uma amostra válida de 149 empresas cadastradas na Federação das Indústrias do Estado do Paraná (FIEP), os dados foram obtidos por meio de questionário (Apêndice) estruturado cujas questões buscaram captar as prioridades estratégicas e foram elaboradas em escala de 1 a 10 pontos, e sua análise foi desenvolvida por meio de regressão logística. Pela análise dos resultados foi possível perceber a importância das prioridades estratégicas para o gerenciamento das empresas e verificou-se que tanto a prioridade estratégica de diferenciação como a de custo, tiveram influências no desempenho das empresas. As prioridades estratégicas de diferenciação demonstraram influência no uso de três ferramentas de controle gerencial: o orçamento, a análise custo/volume/lucro e o balanced scorecard. A prioridade estratégica de liderança de custo demonstrou influência em duas ferramentas: gestão ABM e a análise de medidas econômicas de desempenho.
Hipocrisia organizada e fachada organizacional nos relatórios de sustentabilidade corporativa
Authors: Machado de Souza Franciele , Douglas Colauto Romualdo , Panhoca Luiz
Published: September 2020

O discurso da sustentabilidade está se tornando onipresente em reuniões de negócios de alto nível e cúpulas de líderes globais. Ainda assim, uma lacuna significativa persiste entre o discurso da sustentabilidade empresarial e a prática. Numa tentativa de avançar na compreensão sobre os Relatórios de Sustentabilidade Corporativa, propõe-se a utilização de uma visão teórica mais matizada, através das lentes da Hipocrisia Organizada e Fachadas Organizacionais. Dessa forma, pressupõe-se que as pressões sociais e institucionais exigem que as organizações se envolvam em Hipocrisia Organizada e desenvolvam Fachadas Organizacionais, limitando seriamente as perspectivas de divulgações reais dos relatórios de sustentabilidade. Para ilustrar este fato, este estudo teve como objetivo analisar a influência das pressões sociais e institucionais sobre o conteúdo das divulgações de sustentabilidade no que se refere à coerência entre o discurso e a ação da empresa Samarco. Os achados mostram que, o caso do rompimento da barragem do Fundão, evidencia a necessidade de agregar ao modelo de negócios das empresas aspectos reais relacionados à sustentabilidade e a gestão de riscos. Entender os impactos que a atividade econômica das organizações pode causar à sociedade, meio ambiente e economia deve ser prioridade na tomada de decisão, de modo que os riscos mapeados sejam totalmente inseridos e mitigados, a fim de prevenir externalidades negativas inerentes ao negócio.

Published: September 2020

O ambiente dinâmico do meio empresarial, decorrente dos avanços que geram mudanças tecnológicas, econômicas e sociais, requer que as empresas adotem práticas de gestão mais sofisticadas para obter vantagem competitiva frente aos seus concorrentes. Nesse sentido, a Gestão Estratégica de Custos (GEC) contribui com os métodos da contabilidade com foco nos concorrentes para a análise dos custos pela perspectiva externa à empresa. Diante disso, o objetivo deste artigo é identificar as informações resultantes da aplicação dos principais métodos da contabilidade com foco nos concorrentes em dois bancos brasileiros, utilizando como fonte de dados exclusivamente informações públicas. A metodologia utilizada para o desenvolvimento do estudo é qualitativa, descritiva e documental.

The present paper explores the effects of deep cryogenic treatment (DCT) on the properties of WC-Co cemented carbides. The investigation involved four different cemented carbide (CC) grades. Two of them were coarse-grained WC with grain sizes larger than 6 μm and binder fractions of 10 and 15 wt. %. The other two were fine-grained with WC grains of 0.5-0.8 μm and the same binder fractions of 10 and 15 wt. %. Their specimens were ground and polished to prepare them for DCT. In each specimen, one half of this polished surface was used for testing the properties of the CC before cryogenic treatment. The post-DCT properties were then determined on the other half. Properties of the cemented carbides prior to and after DCT were studied using optical and scanning electron microscopy, X-ray diffraction, hardness testing according to Vickers scale followed by calculation of fracture toughness KIC and a ball-on-disk test of the wear resistance of the surface. One of the findings was that cryogenic treatment led to a decrease in residual stresses and to lower fracture toughness KIC in the CC.

Published: September 2020

In this study, the effect of the β-Al5FeSi phases on fracture surfaces in secondary AlSi7Mg0.3 cast alloys with common and higher amount of iron was investigated. Iron addition caused the formation of different Fe-rich intermetallic phases in aluminium alloys. Components made of secondary aluminium alloys commonly have a higher amount of such phases. Sharp needles as β-Al5FeSi phase lead to initiate stress tension, thereby contributing to increased risk of micro-cracks formation on the fracture surfaces. To determine the effect of β-Al5FeSi to fracture surfaces of AlSi7Mg0.3 cast alloy, SEM microscopy with energy-dispersive X-ray spectroscopy (EDX) was used to study the amount of needles phases, their morphology and violation wave. It was found that increasing Fe content increased the size and the number of Al5FeSi phases. The fractographic analysis of fracture surfaces shows an increasing amount of cleavage fracture in materials with a higher amount of iron, too.

In recent years, solid waste of the production of mineral fertilizers, phosphogypsum, has been of great scientific and practical interest in construction. The results of scientific research and practical experience in many countries have convincingly proved the technical feasibility and feasibility of using phosphogypsum. The problems of reducing impurities of phosphorus and fluorine in the manufacture of building materials from phosphogypsum are considered. Comparative experimental studies of the presence of phosphorus impurities for the initial phosphogypsum of the Dnieper Mineral Fertilizer Plant, calcined phosphogypsum and mixtures of phosphogypsum were carried out. Comparative indicators of the presence of radioactive elements in phosphogypsum are given. It is shown that there are methods for reducing heavy metals in phosphogypsum.

Published: September 2020

The paper presents the results of the development of a special group of cast composite materials based on nodular cast irons. The alloys were based on alloying cast iron with copper in amounts that exceed its solubility in liquid Fe-C-Si systems (Cu>6 wt.%). A new component is obtained in the structure of castings in the form of a complex mixture based on the Cu-phase. Inclusions are relatively large (up to 200 μm) and globular in shape, with a uniform allocation in the volume of the castings. This favorably distinguishes the obtained alloys from the known cast irons and gives them high antifriction properties. With isothermal hardening, it is possible to obtain the lowest values of wear for structures of lower bainite. Developed cast composite materials are recommended to be used as tribotechnical materials working in conditions of poor lubrication and corrosion.
Doc Hay: A Chinese Herbalist Combating the 1918–1919 Influenza Pandemic in America
Authors: Chen Yemeng
Published: September 2020

This is a story about a Chinese herbalist Ing “Doc” Hay who combated the 1918–1919 influenza pandemic in the America West. As an immigrant, he came to the States as a laborer, but he had knowledge of Chinese herbal medicine due to his family heritage. This made it possible for him to start practicing in the Chinese community in John Day, Oregon, until 1948 when he retired. During the time of the pandemic running wild in the 1910s, he prescribed formulas aimed at flu and boiled herbal decoction, personally delivering it to a working site for those Chinese laborers as well as non-Chinese patients. None of the laborer patients treated by him died during this deadly pandemic. Due to his success and fame, his practice was booming even after the Chinese community disappeared in John Day in later years. Doc Hay is always remembered in the history of earlier development in eastern Oregon, so that the site of his practicing, Kam Wah Chung and Co. Building, is now a national historic landmark. And more importantly, he has also been remembered by Chinese herbal medicine practitioners in the United States.
International Communication of Traditional Chinese Medicine in the Context of COVID-19 Pandemic by Analogy of Directional Solidification
Authors: Cai Yingwen , Shen Xueyong
Published: September 2020

According to the phenomenon-taking of classified analog, directional solidification can be an excellent approach for international communication of traditional Chinese medicine (TCM) in the context of COVID-19 pandemic. Attitudes toward TCM by Western Medicine (WM) can be represented by various morphologies of the solid/liquid interface. COVID-19 has created an urgent need for the worldwide spread of TCM. To counter any doubts and objections against TCM, COVID-19 pandemic provides a good opportunity, meanwhile a steady and firm pace forward should be kept. It is also necessary to resolve domestic controversies and to lower cultural shock. The philosophy of TCM can agree fairly well with dialectical materialism; the scientific connotation of pentacy in TCM can be explained through the symptoms of COVID-19-infected patients. A TCM understanding compatible with WM will accelerate its international acceptance, which could help to better elaborate the significance of humanity in TCM. Holistic medicine under the guidance of TCM principles is an important trend in medical development, whose framework is illustrated in a 4C+T diagram.
Thoughts on Coronavirus Disease 2019 Based on JingFang Medicine (Classical Chinese Formula) Solutions for COVID-19
Authors: Huang Huang
Published: September 2020

This article aims to provide some thoughts on the prevention and treatment of Coronavirus Disease 2019 (COVID-19) from the perspective of JingFang Medicine (Classical Chinese Formula). It is believed that the vague theoretical understanding of COVID-19 in Traditional Chinese Medicine does not hinder the precise treatment of the disease by following the rule of “With this Zheng, prescribe this Fang.” According to the principle of “Fang-Zheng Correlation” and the knowledge gained from the thousands of years of experience in treating febrile diseases, Xiao Chai Hu Decoction (小柴胡汤) and its modifications are recommended with the emphasis on individualized treatment. As another form of practicing “Fang-Zheng Correlation,” generalized group treatment should also be paid attention to. Giving considerations to the historical medical data, Jing Fang Bai Du Powder (荆防败毒散) and Shi Shen Decoction (十神汤) are recommended for group prevention treatment. Assisting the Zheng (Upright) Qi and using tonic formulas are two entirely different concepts. According to the principle of “Fang-Zheng Correlation,” tonics abuse should be avoided in the prevention of COVID-19, and the using of Huang Qi (黄芪 Radix Astragali seu Hedysari) should also be very carefully done.
Key to Treating COVID-19: Removing Phlegm from Small Airways
Authors: Wang Qingqi
Published: September 2020

According to autopsy reports, patients who died from COVID-19 had a lot of mucus in the lung that obstructed the airways, reduced the effect of mechanical ventilation, and even led to pulmonary failure. Traditional Chinese medicine literature mentions that “Inability to remove phlegm impairs the lung, which leads to death.”Hence one of the most urgent problems to be solved is to remove phlegm from the small airways. This article elaborates ten methods to remove phlegm for clinical reference.
