Ethical Dilemmas of Emerging Latina Researchers: Studying Schools Serving Latina Communities
Authors: Morales P. , Monzo Lilia
Published: March 2021

This article explores some of the ethical dilemmas we have encountered as emerging Latina researchers in dual language school contexts. Informed by Chicana Feminist Theory, we attempt to analyze power in more nuanced ways, shifting the analysis of ethics away from traditional notions of power based only within the researcher rather than the participants. While we do not offer solutions to these dilemmas, we raise questions that we hope will spur thoughtful reflection and move the field of educational research into more equitable and ethical research practices across contexts.
My Story: An Authoethnographical Account of Being a PhD Candidate
Authors: Pitcher Rod
Published: March 2021

This paper is an autoethnographical account of my PhD candidature. It shows how the work affected my development as a researcher and also as a person. As I near the end I realise that the process of doing a PhD has changed me beyond recognition. I am no longer the naive undergraduate student of the recent past. I have developed beyond that. I discuss some of the important influences on me during my candidature and how they changed me and my way of thinking about myself and my work.
Living with Cancer Aged 75 and Older: A Biographical Narrative Case-Study
Authors: Hughes Nicholas
Published: March 2021

Aging is associated with greater incidence of disease and illness, including cancers. Extensive literature reports incidence, prevalence, and treatment of cancers in older individuals. The subjective perceptions of older individuals undergoing the experience of cancer remain largely unknown. The case-study reported in this article is derived from a larger study whose aim was to investigate the experiences of older people of living with cancer. Data were generated using narrative interviews with 20 individuals aged 76-87 diagnosed with one of four common cancers. Interview data were analysed using the concept of the “illness trajectory” (Corbin & Strauss, 1988). In this article I present a single narrative revealing a detailed and nuanced progression of events and reactions during the experience of cancer. The cancer story reported here is interpreted as a restitution narrative (Frank, 1995) in which the teller reports movement from an altered status (a damaged body) towards recovery and a return to “normal” (a body restored to health). Some features of this story show health care practitioners and services working effectively to provide treatment and care, but other elements of this individual narrative suggest that some outstanding challenges remain to provide the best care for elders with cancer.
Consumers' Motivations and Daily Deal Promotions
Authors: Ardizzone Antonella , Mortara Ariela
Published: March 2021

In the last years daily deal (dd) sites have become a substantial part of e-commerce scenario. Every day, for a limited time, such sites offer their subscribers, at very discounted prices, deals for products or services. Despite the worldwide success of daily deal sites, testified by articles in newspapers and magazines, there is an almost complete absence of academic research on this topic. The aim of this paper is to understand the consumers' drivers in online coupon buying. The study is exploratory in nature and authors have collected data by carrying out four synchronous online focus groups involving 21 participants and investigating five areas: level of awareness, perception area, social dimension, consumer behavior, and relationship with e-commerce. Respondents show a high level of awareness of daily deal sites. In the perceptive area, convenience emerges as the driving factor in coupon buying. As to the self-perception area, some ambivalences emerge between smartness and compulsive buying, highlighting also some dissatisfaction. The ‘social dimension’ is almost irrelevant, and as to consumer behavior, daily deal buying seems to be a kind of fashion. Consumers perceive the bargain side of the offer, behaving like “cherry pickers.”
World of Warcraft: A Family Therapist's Journey into Scapegoated Culture
Authors: Jordan Nickolas
Published: March 2021

Relational (online) video games are lucrative business. The extremely popular Massive Multiplayer Online Role Playing Game, World of Warcraft, boasts over eight million paying users. Video games are also a lightning rod for criticism and contempt by news media, parents and policy makers as the number of mass shootings increases in the United States. There is some research suggesting violent video games increase violent cognition and behavior. There is other research arguing no relationship exist between violent gaming and aggression. The same dichotomy of views exists within the discussion of how relational video games impact intimate partnerships. The purpose of this study is to continue conversation into the possibility of using games like World of Warcraft as interventions in individual, couple and family therapy. This autoethnorgraphic work examines researcher experience in World of Warcraft and its impact on violent thought, behavior and intimate relationships. In addition to researcher self-exploration, extensive interviews were conducted to provide additional context. Throughout the course of this work, three themes of World of Warcraft culture emerged: Work, Nostalgia and Connection. The theme of connection was most pervasive to the researcher and the participants. Video games like World of Warcraft may present supplemental opportunities for clients to practice healthy connection. Concerned parents should monitor their children’s online gaming relationships as they would any other. Future research in this area may benefit from an experimental design where video games like World of Warcraft are used in the treatment of PTSD and Social Anxiety Disorder.
Methodological Considerations for Qualitative Research with Immigrant Populations: Lessons from Two Studies
Authors: Lu Yu , Gatua Mary
Published: March 2021

Often, research strategies are guided by principles developed based on mainstream U.S. cultural norms. Immigrants, however, may differ in their cultural backgrounds and previous exposure to research. Commonly adopted research procedures, such as the informed consent process, may be culturally inappropriate for research with culturally diverse populations, and hence require cultural adaptations. Based on two qualitative studies, this paper describes the methodological issues encountered in the field when working with Chinese and Kenyan immigrants, and explains how these issues were resolved. Comparing and synthesizing experiences from the two studies, recommendations for methodological adaptations when working with immigrant populations are provided. Specifically, suggestions on how to prepare the research protocol, recruit participants, obtain informed consent, deal with unanticipated incidents during the research process, and choose the interview language(s) are discussed in depth.
Breaking the Silence of Mainstream Teachers' Attitude towards Inclusive Education in the Bahamas: High School Teachers' Perceptions
Authors: Cambridge-Johnson Janelle , Hunter-Johnson Yvonne , Newton Norissa
Published: March 2021

There has been a paradigm shift globally regarding the adoption of inclusive education policies and procedures. However, teachers still have varying views, anxieties, and preconceive misconceptions about the successful implementation of inclusive education practices in the general education classroom. This study utilized a qualitative approach to provide an informative exploration of teachers’ attitudes toward inclusive education and its implementation, possible factors that influence teachers' attitude, and recommendations for promoting best practices in inclusive education. Data was collected utilizing semi-structured interviews from eight teachers throughout the New Providence District in the Bahamas. The results of the study revealed that teachers generally had positive attitudes toward inclusion. However, lack of funding, administrative support and minimal opportunities for training and development were identified as negative influential factors regarding teachers’ attitude towards inclusive education.

Water and sanitation are the most important services necessary for life and dignity of citizens. But slum dwellers are excluded from these services, resulting in environmental degradation, marginalization and poor health. Through inquiry based learning, the first author has attempted to give his students an first hand and innovative learning experience by helping them to explore water and sanitation issues in the Ambujwadi slum of Mumbai (India) on their own. The paper highlights the pedagogical approach and by the way of illustrations helps the reader to understand its usefulness in teaching students of social work.
An Exploration of Collective Meaning-Making among Migrant Workers
Authors: Selvaraj Patturaja
Published: March 2021

I engaged with workers in India who have migrated from rural districts in the southern state of Karnataka to work in the mess of an academic institute located in a western state of India. These workers faced significant challenges and vulnerabilities due to being part of the unorganised sector. The primary question for my inquiry was to understand how migrant workers negotiated these vulnerabilities and whether they could succeed in processes of informal collectivisation based on shared bonds of language and ethnicity. I interviewed six migrant workers to understand their experiences and difficulties they face. I analysed the data by building themes within and across the interview data. One of the findings of my study is that the collective identity of migrant workers who are involved in preparation of South Indian food items emerged through various symbolic acts in their living and work spaces.
Research in Special Education: Using a Research Poem as a Guide for Relationship Building
Authors: Cousik Rama
Published: March 2021

Building positive relationships with participants is an important component of qualitative research in the field of special education. Research poems allow expression of the evolution of participant-researcher relationship in a sensitive and nuanced manner. In this paper, I use a research poem about gardening to demonstrate how a researcher can construct a positive relationship with his/her participants. Each line of the poem represents the sequence and evolution of relationship development between the researcher and families who participated in the research.
Disabilities Disabilities: A "Two-Way Mirror"
Authors: Thomas Kathy
Published: March 2021

There is nothing more intriguing than well-reported documented stories of real life experiences and genuine autoethnographic dialogue. When writers communicate and relate stories about the self and their experiences and include others who share a personal story, there is an amazing connection, unique intensive and extensive understanding and interpretation, and a cultural and social exchange in an authoethnographic representation of self and the respective culture of study. A dialogue generated among the authors as educators as they shared stories inside and outside the disabilities culture was the performance and autoethnographic delivery in Phil Smith’s book, Both Sides of the Table: Autoethnographics of Educators Learning and Teaching Within/in [Dis]ability. For Smith’s purpose, both sides of the table represent both parties negotiating an academic Individualized Education Plan (IEP) for individuals with disabilities. The transitions from self to group and the ability to move freely inside and outside the culture as a member of the culture, presents a “wider lens” as one often hears in the autoethnographic and ethnographic language needed to gain a more complete picture of what it is you want to know and learn, and what is permissible to reveal. An autographic lens is widely accepted for this dialogue (Chang, Ngunijiri, & Hernandez, 2013; Creswell, 2013; Ellis, Adams, & Bochner, 2011). Pragmatically, autoethnography was a method realistically supported by the voice of these educators with a unique understanding of their own disabilities world and a story to tell.
The Influence of Confucianism on Identity Formation of a Multi-Skilled Migrant: An Autoethnography
Authors: Fung Annabella
Published: March 2021

In this autoethnographical study, I examine how my identities were influenced by Confucianism. Two main Confucian concepts were examined: “selfperfection,” and “filial piety and submissiveness.” As a migrant who left Macau for Australia at fifteen, I have been immersed in diverse cultural climates, experienced gender bias, identity crisis and racial discrimination. I consider all experiences as essential steps of my evolution with ethnographic, interpretative, phenomenological and narrative understandings. This paper introduces the term “seasonal fluctuations” as a way to describe the changing meanings of my lived experiences that were interrogated by my three distinctive personalities: The Writer, The Interpreter and The Observer. This triple hermeneutics is borrowed from Interpretative Phenomenological Analysis. For me, my gender, birth place and birth order had pre-determined my fate before learning took place. The Confucian values that my family and I adopted further shaped my identities. Issues of gender equity and social justice had been discussed in the interrogation of my story, my identities remain fluid. Finally, the challenges and benefits of conducting an autoethnography were discussed. I acknowledge that qualitative research can have a transformative influence on the individuals conducting the inquiry, as we reflect on our participation in the world around ourselves.
What's wrong with Me?: An Autoethnographic Investigation of the Co-Cultural Communicative Practices of Living with Tourette Syndrome during Adolescence
Authors: Congdon Mark
Published: March 2021

Using an Autoethnographic methodology, this essay explores how I was diagnosed with Tourette Syndrome. My experience illustrates a dynamic and difficult process of understanding and negotiating assimilation, using a variety of communication strategies related to self-perception, perceptions of others, and interactions with others. Using Co-Cultural theory (CCT) as a theoretical framework, three themes emerged from my experience: (1) nonassertive assimilation: negotiating with relationships of authority, (2) aggressive assimilation: negotiating relationships with peers, and (3) nonassertive separation: the convergence of negotiating relationships of authority and with peers. It is my hope that my story expands the awareness and conversation among and within academia regarding the influence that dominant cultural groups, norms, and labels have on the experience of adolescence living with TS as it relates to educational experiences.

Maize density is an important factor in cultivation which has significant effect on growth parameters. Newer hybrids have greater grain yield at higher plant densities than older hybrids. Differences in grain yield between older and newer maize hybrids were shown to be a function of plant population density. Optimum plant density for maximum grain yield per unit area may differ from hybrid to hybrid on account of significant interactions between hybrids and densities. Modern hybrids have shown tendencies to withstand higher levels of stress (i.e.- low N, high plant densities), which allow them to better sustain suitable photosynthetic rates, appropriate assimilate supplies, and maintain plant growth rates attributable to enhanced mineral nutrition and water use efficiency.

Soybean yield depends on the variety, soil, cultural practices, as well as the weather conditions in certain years. The aim of this research is to examine the impact of NPK fertilizer application in the autumn and spring period on the level of soybean yield. The highest soybean yields were achieved by applying NPK fertilizer in autumn, before the basic tillage with spring application of nitrogen fertilizer AN. Spring application of NPK fertilizers and AN increases the yield, but the effect of fertilizers is significantly less compared to autumn application. The application of nitrogen fertilizer AN increases the soybean yield, and in order for this fertilizer to show its full effect, it is necessary for the soil to be optimally provided with macroelements.

"Esta é a primeira coletânea de pesquisas relacionadas à educação básica que eu e minha parceira de estudos, Taís Pelição, temos a satisfação de organizar e apresentar. Este projeto surgiu por uma necessidade encontrada na prática de nossas vivências como professoras de ensino fundamental e ensino médio. Isso porque nos últimos três anos, com a homologação da Base Nacional Comum Curricular – BNCC (2017) e também o novo currículo do Estado de São Paulo (unidade federativa em que atuamos), denominado Currículo Paulista (Volume1, 2019 e Volume 2, 2020), deparamo-nos com diretrizes que exigiam ainda mais o trabalho conjunto entre os agentes escolares (gestores, professores e estudantes).[...] [...]Assim, a partir de discussões a respeito de formas que pudessem auxiliar o processo de integrar disciplinas, chegou-se à ideia de unir textos que poderiam dialogar diretamente com professores, usando uma mesma linguagem: experiências vivenciadas e pesquisas realizadas por pessoas comprometidas com a educação, que compartilhassem o carinho pelo ensino-aprendizagem de seus alunos".

The analysis of emergency rescue equipment usage on the territory of the Republic of Belarus made it possible to identify that the main technical unit involved into emergency situations is a fire truck tank. One of the main reasons for its repair and withdrawal from operational status is tank leakage that occurs due to peculiarities of equipment usage. As a result of a complex of studies, the recommendations for the modernization of a standard tank with 5 m3 volume of a fire truck were developed on the MAZ-5337 chassis. The stress state of a standard and modernized tank of a fire engine was investigated by the strain-gauge method under various operating modes of movement.
ELASTIC BENDING OF A THREE-LAYER CIRCULAR PLATE WITH STEP-VARIABLE THICKNESS
Authors:   Belarusian State University of Transport, LEONENKO Denis V.
Published: March 2021

The bending of a three-layer elastic circular plate with step-variable thickness is considered. To describe kinematics of asymmetrical in thickness core pack, the broken line hypotheses are accepted. In thin bearing layers, Kirchhoff’s hypotheses are valid. In a relatively thick filler incompressible in thickness, Timoshenko’s hypothesis on the straightness and incompressibility of the deformed normal is fulfilled. The formulation of the corresponding boundary value problem is presented. Equilibrium equations are obtained by the variational Lagrange method. The solution of the boundary value problem is reduced to finding three required functions in each section, deflection, shear and radial displacement of the median plane of the filler. An inhomogeneous system of ordinary linear differential equations is obtained for these functions. The boundary conditions correspond to rigid pinching of the plate contour. A parametric analysis of the obtained solution is carried out.
APPLICATION OF LOGISTIC REGRESSION IN CALCULATION OF DAMAGEABILITY OF SOLID DEFORMABLE BODY
Authors:   Belarusian State University, MARMYSH Dzianis E.
Published: March 2021

The paper proposes a logistic regression model for estimating the damageability of a solid deformable body. A training sample is randomly generated from a uniform distribution over the area containing the dangerous volume. For linear separability of the training sample, a classifying kernel is used in the form of a radial basis function. The regression parameters were estimated using the maximum likelihood method, then the system of nonlinear equations was solved by the Newton–Raphson method. To determine the quality of the classifier, a ROC analysis was performed, which consists in constructing the ROC curve and calculating the area between the ROC curve and the specificity axis. For adequate assessment of the work, the logistic regression model is used to calculate the damage of a half-plane when a normally distributed load acts on its boundary. The paper also analyzes the stability of the model parameter estimation algorithms when generating a random sample of training sample.

Disadvantages of the traditional description of a mechanical engineering product are shown, which are based on technological features oriented to single, typical and group operations of the technological process. It is proposed to represent the design of the product and its parts with a structured set of relevant technological modules, in the form of a graph of a hierarchical structure. The availability of a unified methodological base makes it possible to control the development of constructively complex products, minimize duplication in the creation of new designs and effectively develope resource-saving technologies for their manufacture. The choice of the method for assessing the manufacturability of the product design is substantiated by the labor intensity of the processes at the stages of its life cycle and the formation of a set of criteria that generalize the assessment of design and technological solutions by coefficients that take into account their degree of influence on the technical and economic indicators of the processes. On the basis of a technical and economic analysis, a method for the integral assessment of production manufacturability in the product life cycle has been formed. The method combines various coefficients of manufacturability, taking into account the degree of their influence on the labor intensity of production and maintenance, repair and disposal of the product structure. Based on the results of the feasibility study, it was proposed to understand the manufacturability of the product design at the stages of its production and disposal as production adaptability.
OPTIMIZATION OF SYNTHESIS PROCESS OF NANOSTRUCTURED CARBIDE-CORUNDUM SILUMIN MODIFIER
Authors:   Joint Institute of Mechanical Engineering of the NAS of Belarus, ORDA Dmitry V.
Published: March 2021

A mathematical model is developed for the process of synthesis of nanostructured modifier TiC-Al2O3 by gasphase deposition based on the system of starting materials TiO2-Al-C. To construct the response equation in the form of a polynomial of the second degree, the experiments were carried out in accordance with the model of a rotatable composite plan of the second order with three factors, including 20 experiments. The main factors considered were the isothermal holding temperature T (°C), the isothermal holding time t (s), and the proportion of the chlorinating component Q (wt.%), and as a response function — the proportion of titanium carbide q(TiC) (wt.%) in the composition of the synthesized modifier. The paper describes the results of computational and experimental modeling, from which it can be concluded that to obtain a modifier with the highest content of titanium carbide, the synthesis parameters should be as follows: T = 900–930 °C; t = 2–2.5 h; Q = 4–4.5 wt.%. The resulting TiC-Al2O3 modifier contains 34 wt.% TiC and has a nanostructured structure, with spherical and filamentous particles which diameter does not exceed 100 nm.
DEVELOPMENT OF THE CONCEPT OF ENTROPY: FROM THERMODYNAMICS TO COSMOLOGY. PART 2. HYPOTHESIS OF ENTROPY IN COSMOLOGY AND ITS DEVELOPMENT

Published: March 2021

In the work [7], the classical concepts of thermodynamic entropy are systematized and modern approaches to assessing the tribo-fatigue and mechanothermodynamic entropy of non-additive systems are outlined. In this article, the concept of the analogy of thermodynamics and mechanics of black holes is presented and analyzed, which made it possible to estimate their (thermodynamic) entropy. The insufficiency of this concept is that thermodynamic entropy is a characteristic of energy dissipation, whereas black holes are characterized by the absorption of energy and matter. In this regard, it is proposed to consider the event horizon as a hermodynamic medium, and a black hole as a tribo-fatigue object. And then the “black hole — event horizon” system is presented as a combined mechanothermodynamic non-additive multisystem. Methods for estimating the total (mechanothermodynamic) entropy and its components — tribo-fatigue and thermodynamic entropy in black hole mechanics are presented. With regard to individual (specific) zones and objects of the universe, the well-known theory of Zeldovich is accordingly modified: the universe is a thermodynamic medium with discretely distributed (scattered) dense and/or solid bodies (objects) — stars, galaxies, etc. Behavior of such a system (direct and back effects in the universe) are described. The peculiarity of the action of the medium on the stars and, conversely, the action of the cluster of stars on the interaction between them consists in the fact that it is non-Newtonian: action is not equal to reaction. It is the inequality of action against counteraction, which has radically different mechanisms and consequences (results), or, in other words, the imbalance of the universe that determine its general motion in space–time. The changing set of all states is the evolution of the universe. The analysis of possible strategies for the evolution of mechanothermodynamic systems is carried out on the basis of the fundamental principle: the damageability of everything that exists has no conceivable boundaries. This principle is formulated in mechanothermodynamics and used in philosophy to create a generalized theory of the evolution of the material world.
COMPARISON OF SOLUTIONS TO THE BENDING PROBLEMS OF THREE-LAYER PLATES ON THE WINKLER AND PASTERNAK FOUNDATIONS
Authors:   Belarusian State University of Transport, KOZEL Anastasiya G.
Published: March 2021

Solutions of problems on axisymmetric bending of an elastic three-layer circular plate on the Winkler and Pasternak foundations are given. The bearing layers are taken as isotropic, for which Kirchhoff’s hypotheses are fulfilled. In a sufficiently thick lightweight, incompressible in thickness aggregate, the Timoshenko model is valid. The cylindrical coordinate system, in which the statements and solutions of boundary value problems are carried out, is connected with the median plane of the filler. On the plate contour, it is assumed that there is a rigid diaphragm that prevents the relative shear of the layers. The system of differential equations of equilibrium is obtained by the variational method. Three types of boundary conditions are formulated. One- and two-parameter Winkler and Pasternak models are used to describe the reaction of an elastic foundation. The solution to the boundary value problem is reduced to finding three desired functions, plate deflection, shear, and radial displacement in the filler. The general analytical solution to the boundary value problem is written out in the case of the Pasternak model in Bessel functions. At the Winkler foundation, the known solution is given in Kelvin functions. A numerical comparison of the displacements and stresses obtained by both models with a uniformly distributed load and rigid sealing of the plate contour is carried out.

Published: March 2021

A statement is given for the boundary value problem of non-axisymmetric deformation of an elastic threelayer circular plate in its own plane. The plate contour is pinched. Physical equations of state in the plate layers are described using the linear theory of elasticity, taking into account temperature influence on the elastic characteristics of materials. Equilibrium equations are obtained by the Lagrange variational method. Boundary conditions on the plate contour are formulated. The solution of the boundary value problem is reduced to finding the radial and tangential displacements in the layers of the plate. These displacements satisfy an inhomogeneous system of ordinary linear differential equations. To solve it, the method of decomposition into trigonometric Fourier series is applied. After substituting the series into the original system of equilibrium equations and performing the corresponding transformations, a system of ordinary linear differential equations is obtained to determine the four radial functions in each term of the series. The analytical solution is written out in the final form in the case of cosine radial and sinusoidal circumferential loads that depend linearly on the radial coordinate. The load is applied in the middle plane of the filler. Numerical approbation of the solution is carried out. The dependence of radial and tangential displacements on polar coordinates and temperature is investigated. Graphs of changes in displacements along the radius of the plate for different values of the angular coordinate are given. The weak dependence of displacements on temperature is illustrated when the plate contour is fixed.

Authors: Wang Sihua , Wang Junjun , Long Chen , Lei Zhao
Published: March 2021

Some studies have shown that the operating state of silicone rubber insulators is not only affected by surface corona discharge, but also different due to the surface covered with different pollutants, but few studies have linked the two. In this paper, by designing the corona discharge test of silicone rubber insulator, the output of nitric acid from its surface product was calculated, and the concentration of nitric acid under different air humidity was obtained. The solubility test of slightly dissolved salt calcium sulfate in nitric acid solution at 293.15K and 333.15K was designed to obtain the solubility of calcium sulfate at different concentrations of nitric acid at two temperatures. Finally, a quantitative analysis of the solubility of calcium sulfate on the surface of insulator FXBW-10/70 in nitric acid solution shows that the surface contamination of insulator with good hydrophobicity may be completely dissolved by nitric acid solution, but the surface of insulator with loss of hydrophobicity cannot be completely dissolved by nitric acid. This study provides a theoretical basis for the dissolution characteristics of silicon rubber insulator corona discharge on its surface soluble salt composition and provides a new idea for the influence of insulator corona discharge on its electrical properties.
La tv come casa dell’arte. Sperimentazioni e utopie
Authors: Bordini Silvia
Published: March 2021

The involvement of art in tv devices is examined from a double point of view: on the one hand, the use of tv as a divulgation tool that compares the history of art, entertainment and spectacularization; and on the other, the interpretation of tv as a tool for artistic experimentation. The hypothesis of a cultural use of the potential of audiovisual communication is elaborated in particular by numerous art historians, with different initiatives that reflect the variants of the very notion of art history and art criticism. The hypothesis of TV as a possible tool for making art according to unprecedented linguistic modulations starts from Lucio Fontana in the context of spatialist theories and then develops autonomously in the specific of new technological languages: the programs, the devices and the physicality of the television itself were in fact the first "material" that the artists used to elaborate what went down in history as "videoart". In the paths outlined in this short essay, television has taken on the significance of a strongly symbolic medium, in the alternation of different and often contrasting messages and models, linked to a variety of cultural and ideological positions.
L’invenzione della tv in Italia nell’ esperienza di Mario Sasso.
Authors: Gazzano Marco Maria
Published: March 2021

Mario Sasso, painter and videoartist, has gradually made the expressive exploration of new technological languages the privileged area of his experience. However, he is also known to the general public for being the most sensitive "art director" of television graphics, an activity in which, since the 1960s, and in particular for Rai-Radiotelevisione italiana, he has transfused the richness of his plastic research.
Sasso is the main architect of the "image" of Italian public television: of that particular way of presenting himself and being recognized, beyond the programs, in peculiar signs and graphic layouts that the artist himself has conceptually contributed to conceiving: innovating and proposing in new ways the languages of nascent television. Made by him are the first “covers”, the first broadcast opening credits of Rai and its flagship programs; as well as a whole series of expressive innovations that have marked the history of the audiovisual sector. Furthermore, operations of destructuring and intersection of artistic languages that have contributed to building the identity of the medium in Italy even before the official affirmation of the electronic arts and up to the pioneering experience of RaiSat.
Se la tv è un white cube. Trasmissioni dell’arte nella televisione italiana degli anni Novanta
Authors: Fameli Pasquale
Published: March 2021

During the 1990s, artists, critics, animators and tv authors saw the possibility of a fruitful dialogue between their respective areas of expertise. This relationship between art and television, however, took place under the banner of a reciprocal rethinking of the two entities: in some cases the medium conditioned artists to the point of inducing them to define specific operating methods or to transform their own works, in others, on the other hand, it was the transmission of the works themselves that “reinvented the medium”. The performative incursions carried out by the duo Formento Sossella and Arpiani Pagliarini for popular programmes such as Blob, Forum and Uomini e Donne are indicative of a thinning between reality and fiction that is typical of the television world and that, not by chance, also affects a good part of Italian art of the decade. The broadcast on Rai Tre of shows such as Prima Puntata and Arte Video TV in the mid-1990s attests to the unexpected possibility of redefining television as a sort of artistic installation connected to specific exhibition occasions. The activity of Leonardo Carrano for L’Angelo (Fininvest) and the collaboration between Paolo Canevari and Alberto D’Amico in the context of Blobcartoon (Rai Tre) are two interesting cases of semantic shift of the work and the dissolution of its unity within the new visual paradigms. The contribution examines these experiences verifying each time their respective implications.
Note sul rapporto tra artisti e televisione italiana delle origini
Authors: Garofalo Damiano
Published: March 2021

This paper aims to reconstruct some of the issues that revolve around the role played by artists in early Italian television in a discursive and non-exhaustive way. The principal aim is to discuss how the study of the television experiences of many visual artists can help to re-read some issues in the field of television historiography. First of all, the importance of the sources and their necessary integration in the study of this relationship will be underlined, with particular reference to the problem of accessibility (see the Rai experimental programs produced between 1952 and 1954). Secondly, we will focus on the relationship between arthouse and popular culture, as it emerges from early Italian television and develops, over the following years, in the debate between entertainment television and art television. As a third question, we will focus on a marginalized element, that of the audiences, and we will discuss what kind of negotiations the art consumption through television implies. Through these three issues some possible lines of research will be drawn in order to try to broaden the approaches and perspectives of television historiography.
Improving India’s Pandemic Response through a Health Information System Reform
Authors:   Schulich School of Medicine and Dentistry at Western University, London, Ontario, Canada, Cossidente Christian
Published: March 2021

Despite stringent lockdown measures to curb the spread of the 2019 Coronavirus disease (COVID-19), India remains vulnerable to an uncontrolled rise in the number of cases and deaths. Furthermore, in spite of the high number of recorded cases, the actual case counts may be much higher due to poor data reporting of probable and confirmed cases of COVID-19 from all of India’s states. Being a populous country with the potential to become the world’s COVID-19 epicenter, it should be the Indian government’s top priority to strengthen India’s health information system (HIS) to support their infectious disease response. To ensure that this paper is guided by current research on India’s HIS performance, a search strategy was developed on Ovid MEDLINE using database-specific subject headings and text words. The search terms used included: “health information systems” AND “India” AND “COVID-19” OR “Coronavirus.” Most district level COVID-19 information management is still paper-based, and with India’s vast terrain, this approach is prone to data compilation errors. Furthermore, India’s fragmented HIS has led to ineffective collaboration between COVID-19 response agencies at the central, state, and district levels, thereby creating barriers pertaining to the compilation and coordination of COVID-19 data. Investing in the use of technology is a viable approach to strengthen the country’s HIS performance during an infectious disease pandemic. To address the challenges associated with India’s fragmented HIS, the government is encouraged to implement a national regulatory body to monitor health information inputs and outputs.
The Performance of Trading Strategies Based on Deviations from Put-Call Parity of Stock Options
Authors: Huang Han-Ching , Wen Chien-Sheng
Published: March 2021

According to Cremers and Weinbaum [6], we compute the implied volatility spread by option put-call parity theory. Then, we build strategy based on implied volatility spread and compares it with OS, 52-week high, and contrarian investment strategies to explore whether the investment performance of the implied-volatility-spread based strategy is better than other strategies. Moreover, we combine the implied-volatility-spread based strategy with other strategies to form the two-dimensional investment strategy to explore whether the performance of two-dimensional implied-volatility-spread strategy is better than one-dimensional implied-volatility-spread strategy. The empirical results show that it needs more than one year of investment horizon to get positive abnormal return by implied-volatility-spread based strategy. Otherwise, it will only receive negative abnormal return when the investment horizon is less than one year. In addition, two-dimensional strategy improves bad performance of one-dimensional strategy. After combining the contrarian 52-week high and contrarian investment strategy with implied-volatility-spread strategy, we find that there is the best strategic effect when the holding period is 12 months. Nevertheless, the abnormal returns decrease after the holding period is 24 months.
