Stress, Anxiety, and Depression Symptoms in a Population Sample in The Initial Stage of The Coronavirus (COVID-19) Pandemic Outbreak
Authors: Elrefaey Samah R. I 
Published: August 2020

Context: Changes in everyday life have been rapid and drastic, with the virus surge outbreaks, the death rate escalating, and stringent steps to control the disease spread increasing across regions of the world. While significant attention has been paid to efforts to diagnose people with the coronavirus infection, recognizing the mental health needs of people affected by this pandemic has been ignored relatively. The psychological impact of the Coronavirus Disease 2019 (COVID-19) outbreak and lockdown measures on the Egyptian population are unknown.
Aim: This study assesses levels of stress, anxiety, and depression symptoms in a population sample in the initial stage of the coronavirus pandemic (COVID-19) outbreak and explores its related potential risk factors.
Methods: A cross-sectional design used to conduct the study on a convenience sample of 1010 subjects residing at Benha City, Qalyubiyah Governorate, Egypt. The tool utilized in this study consists of two parts: Self-administered questionnaire, which was designed to assess people's socio-demographic and family data, and Depression, Anxiety, and Stress Scale (DASS) that measure the symptoms of the emotional state of depression, anxiety, and stress.
Results: The result reveals a mean of total stress scale as 15.44±3.62, mean of total anxiety scale as 13.56±3.74, and mean of total depression scale as 12.41±3.86. There was a high statistically significant positive correlation between anxiety, stress, and depression at p-value <0.01.
Conclusion: This study concluded that more than two-thirds of the studied population suffered from a moderate level of stress, less than two-thirds of the studied population suffered from moderate anxiety, while around one-tenth of them were normal, and more than one-third of the studied population suffered from a moderate level of depression, while one-fifth of them were normal. The current result revealed that age (year), marital status, having children, educational level, income, and occupation were predictors of stress, anxiety, and depression. The study suggested the need for additional research on predictive factors affecting people's stress in the era of COVID-19 outbreak and carried out psychological intervention activities through various mediums to help people become more resilient during the COVID-19 epidemic.
Numerical investigation of heat transfer enhancement inside a parabolic trough solar collector using dimpled absorber
Authors: Benabderrahmane Amina 
Published: August 2020

Three dimensional numerical investigation of heat transfer enhancement in a non-uniformly heated parabolic trough solar collector using dimpled absorber under turbulent flow was incorporated in the current paper. The governing equations were solved using the finite volume methods (CFD) with certain assumptions and appropriate boundary conditions. The Monte Carlo ray trace technique was applied to obtain the heat flux distribution around the absorber tube. The numerical results were validating with the empirical correlations existing in the literature and good agreement was obtained. The present results demonstrate that the inclusion of inserts provide a good performance in heat transfer, also the receiver temperature gradient are shown to reduce with the use of geometrical modification, the absorber geometry have a remarkable effect on the HTF velocity distribution.
Comparative study between pi and fuzzy pi controllers for DFIG integrated in variable speed wind turbine
Authors: Hamza Mesai Ahmed , . A. Bentaallah, Y. Djeriri, A. Mahmoudi 
Published: August 2020

This paper presents the contribution of the application of fuzzy logic for the independent control of the active and reactive power stator of a doubly fed induction generator (DFIG), used in a variable speed wind energy conversion system. So in this work, we are particularly interested in the application of indirect vector control by stator flux orientation to the DFIG, based on fuzzy controllers. These latter surpass the limits of conventional controllers and possess essential characteristics for the improvement of the robustness of the vector control with against parameters variations of the system. The obtained simulation results have shown that it is possible to control the stator powers, even in the presence of parametric variations.
Extraction of the electrical parameters of the Au/InSb/InP Schottky diode in the temperature range (300 K- 425 K)
Authors: Sadoun Ali 
Published: August 2020

In this work, we have presented a theoretical study of Au/InSb/InP Schottky diode based on current-voltage (I-V) measurement in the temperature range ( 300 K- 425 K). Electrical parameters of Au/InSb/InP such as barrier height (Φb), ideality factor and series resistance have been calculated by employing the conventional (I-V), Norde, Cheung and Chattopadhyay methods. Measurements show that the Schottky barrier height (SBH), ideality factor and series resistance, RS for Au/InSb/InP Schottky diode in the temperature range (300 K–425 K) are 0.602-0.69eV, 1.683-1.234 and 84.54-18.95 (Ω), respectively. These parameters were extracted using Atlas-Silvaco-Tcad logical.
'GLOBAL, NETWORKED AND COLLABORATIVE': HOW THE NORMALIZATION OF LEAKING SHAPED THE IDENTITY AND PRACTICE OF INVESTIGATIVE JOURNALISM
Authors: Baack Stefan 
Published: August 2020

From the Panama Papers to the Migrants' Files, we appear to witness a 'Golden Age of global muckraking'. While cross-border collaborations among journalists are not new, data technologies have dramatically increased their scale and degree of collaboration. Transnational collaborations among journalists are increasingly data-driven operations specialized on facilitating the analysis of huge leaks. In a more dynamic media environment, where traditional identities and routines of journalism are being challenged, data-driven transnational networks help to articulate global standards of investigative journalism and shape journalism's ability to tackle issues in an increasingly globalized and interdependent world.
This paper shows how data-driven journalism networks today are shaped by the ways in which journalists normalized leaking in technological, organizational, and cultural ways since Wikileaks’ publication of the Afghan war logs. The result has been a) the establishment – or evolution – of national and transnational structures that facilitate collaborations; and b) that the concept of ‘leaking’ was moved away from radical transparency advocacy, and into traditional journalistic ethics and identities. The subsequent normalization of leaking is relevant beyond leaking itself, as it more broadly shapes practices around ‘data-driven cross-border collaboration’. This means that the practices, organizational structures and technologies developed around leaking also shape collaborative data collection or data sharing projects. To examine the future of journalism in a more globalized and datafied world, I will conclude with suggesting that media and journalism studies needs to rely more on theories and methodological frameworks that do justice to journalism’s increasingly transcultural nature.
MARDI GRAS THROUGH INSTAGRAM STORIES: HOW EPHEMERAL MEDIA SHAPE EVERYDAY ENGAGEMENTS WITH IDENTITY POLITICS
Authors: Cassidy Elija , Matamoros Fernandez Ariadna , Thomson T.J. 
Published: August 2020

A third of the world’s population is active on social media and a growing number is sharing ephemeral content on such platforms. Though originally pioneered by Snapchat, Instagram has come to dominate the ephemeral media market and, as of January 2019, boasts half a billion daily Instagram Stories users (Statista, 2019). Launched roughly 2.5 years ago, in August 2016, Instagram Stories offers people a novel way of communicating through sharing photos and videos that, by default, are only available for 24 hours and then disappear. This phenomenon presents unique challenges for researchers but also demands additional attention in order to understand contemporary forms of sociability and meaning-making. This study examines people’s everyday engagements with ephemeral media through an exploration of more than 400 Instagram stories created during the 2019 Sydney Gay and Lesbian Mardi Gras Festival.
Through this empirical work, we aim to examine the place of ephemeral media in everyday communication and to start a public conversation around the Implications of “losing” ephemeral media and how this might impact archival practices for the study of historical events that get heavily mediated through digital media.
REDDIT QUARANTINED: CONSEQUENCES OF DEALING WITH DISTRUST IN SOCIAL MEDIA PLATFORMS THROUGH RESTRICTING ENGAGEMENT
Authors: Copland Simon 
Published: August 2020

Online abuse has become a matter of trust for social media platforms, whose role as a facilitator of public debate has been called into question. In response social media companies have become more active in regulating and banning particular users and channels.
Through the use of affordances theory, this paper examines one example of the regulation of content on a social media site, the revamp of the quarantining function on Reddit in late 2018. Quarantines are designed to halt participation within and growth of subreddits without banning them outright.
The paper uses quantitative and qualitative data to examine the consequences of this revamp on two subreddits, r/Braincels and r/TheRedPill. Through studying activity levels on these subreddits the paper argues that quarantines did limit discussion within these subreddits. However, it also argues that the revamp had unintended consequences, in particular a growth in distrust between subreddit users and Reddit as a site, and a shift of users away from Reddit to less regulated sites.
The paper argues that quarantining shifted the affordances of Reddit, in this instance resulting in greater discouragement of activity on particular subreddits. Using the mechanisms and conditions framework (Davis and Chouinard, 2016) the paper however argues that users adapted to and circumvented this discouragement to continue engaging in particular behavior.
While quarantining had short term benefits, using an affordances framework this paper argues it had unintended consequences, ones which can result in a continued radicalization of actions and beliefs, furthering distrust in the online sphere.
TRUST IN TAIWAN’S MEDIA ECOLOGY, AUDIENCE AND CIVIC ENGAGEMENT: 2018 TAIWANESE LOCAL ELECTIONS AND NATIONAL REFERENDA AS A CASE STUDY
Authors: Chen Pai-Lin , Cheng Yu-Chung , Fu Wen-Cheng , Lin Trisha T.C 
Published: August 2020

This panel presents four papers aiming to examine the significance of the 2018 elections and referenda to Taiwan from the perspectives of instant news, social media, the relationship between online and offline behaviors of citizens, and socially mediated activism. The authors explored media ecology, trust issues toward the audience and civic engagements of these elections and referenda. The research methods of studies presented in this panel are also diverse, ranging from computational methods, national survey, to in-depth semi-structured interview.
The first paper investigates how the online news media construct “liquid reality” in the election-related contents by analyzing instant news from five major online news media outlets in Taiwan. The second paper analyzes the election-related Twitter data by topic modeling and identifies issues, in which “fake news” was in play, and how social trust influence fake news sharing on social media was further discussed. The third paper characterize how the election-related information on social media influenced the offline behavior of the political participants by conducting a nation-wide survey to examine correlation between the online political information consumption behavior and the motivation to participate in real-life political activities. The fourth paper focuses on the relationship among socially mediated activism, fake news, and trust in social media in the referenda of same-sex marriage issues. By interviewing advocacy groups, third-party fact-checking organizations, governmental authorities, and social media platforms, the response strategies to the negative influence of fake news on social activism and vulnerable groups are explored.
‘MARKING THEIR OWN HOMEWORK’: TRUST AND AUDIENCE MEASUREMENT IN THE AUSTRALIAN DIGITAL ADVERTISING INDUSTRY
Authors: Kininmonth Samuel Stanley 
Published: August 2020

This paper examines how the Australian advertising industry debates trust in the infrastructures of digital advertising. The advertising industry is undergoing a major change as digital advertising is increasingly dominated by new advertising technology (adtech) players and major tech companies such as Facebook and Google. These new companies which rely on automated systems of ad targeting, pricing and placement to control large amounts of digital advertising inventory and offer new more ‘efficient’ ways to micro-target advertising.
Yet these companies have garnered reputations for misrepresenting their numbers; a problem compounded by Google and Facebook’s reticence to provide independent audience verification. This has led to a high degree of mistrust from Australian advertisers. Neither Google or Facebook offers serious third-party auditing, leading many in the advertising industry to say that they are ‘marking their own homework’.
In this paper I ask, how is trust of measurement and verification infrastructures debated within the digital advertising industry? Is it fair to compare businesses that distribute advertising in very different ways? I answer these questions through qualitative analysis of submissions made to the Australian Competition and Consumer Commission (ACCC) as part of its current Digital Platforms Inquiry (DPI) in 2018 and 2019. I also draw on summaries of four public forums the ACCC held in 2018 as well as wide reading in the advertising industry trade press. This paper aims to contribute to a better understanding of the role standards and measures play within industry and how they relate to trust during industry transformation.
TOO MANY COOKS: TRUSTING NEW VOICES IN ONLINE CULINARY ADVICE
Authors: Kirkwood Katherine 
Published: August 2020

Digital technology is becoming increasingly enmeshed in the everyday practices of cooking and eating (see Lewis 2018; Kirkwood 2018). In negotiating the increasingly complex web of culinary information online users need to remain vigilant about the voices and perspectives they turn to for food and nutrition advice.
In examining which online sources are trustworthy, this paper adds to the scholarship that highlights how the growing industrialisation of food negatively impacted food literacy (Pollan 2006; Vileisis 2008). In relation to digital food media, Lewis (2018, 214) argues that “food citizens increasingly require a critical media literacy…”. This is important considering that consumers are more likely to turn to the media than nutrition professionals for advice (Contois and Day 2018, 16).
This paper builds on Lewis’ (2018) calls for greater critical media literacy Through textual analysis of online news and popular commentary, this paper examines the two Australian case studies of Australian celebrity chef Pete Evans and fraudulent wellness advocate Belle Gibson. These examples highlight risks associated with online culinary information and provide contrasting perspectives on credibility and trustworthiness. Evans leverages mainstream media exposure and experience as a chef to establish credibility for his online channels where he explores his alternative culinary views more extensively. Gibson’s reputation meanwhile was established through achieving grassroots fame online for supposedly beating cancer through shunning conventional treatments. Understanding how trustworthiness or authority is established and negotiated, and particularly how these characteristics work between legacy and online media are important in developing critical media literacy around food.
“I PREFER TO BUILD TRUST” – EXAMINING PARENTAL CONFIDENCE IN CHILDREN’S DIGITAL SKILLS
Authors: Savic Milovan 
Published: August 2020

Digital and social media has become deeply intertwined into children’s mundane daily routines. Considered to be digital natives, young people are often assumed to be experts in using digital and social media. As they are indeed enthusiastic users of new devices and social media platforms, children might be quick in picking up on platform’s features and affordances. However, their ability for a strategic understanding of risks and opportunities is often questioned. Parental anxiety about children’s engagement with digital and social media stems from their lack of confidence in children’s ability to navigate online risk. While academic research attempted to identify and measure digital skills, less is known how these skills are negotiated in the family.
Drawing on separate home-based interviews with children and parents, this paper looks at the approaches parents use to govern children’s digital and social media use. It discusses how confidence in children’s abilities – or varying degrees of it – affects the parental approach and success in working with their children on developing safe digital practices. Three dominant parental approaches identified across the sample are practices where parents act as *watchdog*, *chaperon* and/or *collaborator*. Central to each of these approaches are varying degrees of trust in children’s ability to engage in safe practices online.
TRUSTED MACHINES? MACHINE LEARNING, MORE-THAN-HUMAN SPEED AND DEAD LABOR IN PLATFORM CAPITALISM
Authors: Taffel Sy 
Published: August 2020

Decision making machines are today ‘trusted’ to perform or assist with a rapidly expanding array of tasks. Indeed, many contemporary industries could not now function without them. Nevertheless, this trust in and reliance upon digital automation is far from unproblematic. This paper combines insights drawn from qualitative research with creative industries professionals, with approaches derived from software studies and media archaeology to critically interrogate three ways that digital automation is currently employed and accompanying questions that relate to trust. Firstly, digital automation is examined as a way of saving time and/or reducing human labor, such as when programmers use automated build tools or graphical user interfaces. Secondly, automation enables new types of behavior by operating at more-than-human speeds, as exemplified by high-frequency trading algorithms. Finally, the mode of digital automation associated with machine learning attempts to both predict and influence human behaviors, as epitomized by personalization algorithms within social media and search engines.
While creative machines are increasingly trusted to underpin industries, culture and society, we should at least query the desirability of increasing dependence on these technologies as they are currently employed. These for-profit, corporate-controlled tools performatively reproduce a neoliberal worldview. Discussing misplaced trust in digital automation frequently conjures an imagined binary opposition between humans and machines, however, this reductive fantasy conceals the far more concrete conflict between differing technocultural assemblages composed of humans and machines. Across the examples explored in this talk, what emerges are numerous ways in which creative machines are used to perpetuate social inequalities.
La formetría aplicada a las deformidades de la columna.

Published: August 2020

La forma de la espalda es un factor importante en la evaluación clínica de varias afecciones
de la columna, en particular de la escoliosis. Se describe un método de análisis de la forma de la
superficie de la espalda que fue ideado para conocer la mayoría de los parámetros necesarios para
evaluar el progreso de la enfermedad en tanto afecte a la forma del cuerpo. La medición de la forma
de la superficie de la espalda y de las marcas anatómicas manuales se analizan a través de un
sistema de ordenador-monitor en el que se escanea el plano de luz incidente sobre la espalda y
desde topografía moiré. Las marcas anatómicas se llevan a cabo para definir los planos de referencia
desde los cuales se comparan sucesivos análisis. Este método se emplea para estimar los ángulos
de las vértebras límites y los ángulos de Cobb. Las secciones laterales muestran la cifosis y
lordosis. Para los resultados se han llevado a cabo correlaciones de la asimetría lateral de la forma
de la superficie con el ángulo de Cobb medido mediante radiografía. Las mediciones se llevaron a
cabo en tres grupos de pacientes (47 pacientes en total). El rango osciló entre r=0.66 a r=0.88,
para una p<0.001. El análisis de los resultados podría reducir en un futuro los exámenes con rayos
X en el evolutivo, por lo evidenciado cuantitativamente y con inocuidad total tanto en la asimetría
lateral como en la deformidad en el plano transverso.
