Binnie lecture 2020: 45 years of dam engineering, part 1
Authors: Gosden John
Published: February 2022

The 2020 Binnie lecture delivered to the British Dam Society on 5th October 2020 is being published in two parts. This first part is a description of three significant projects that were important in my early development and maturing as a dam engineer, drawing out some of the lessons I have leaned on through the rest of my career. One of my underlying thoughts in selecting this theme, was to show how access to such a variety of experiences made it far easier to acquire the knowledge and experience required of a panel engineer when I started, than it is today. The second part presents some views on the development of our current reservoir inspection practice, which may be helpful in the light of the reducing numbers of all reservoirs panel engineers.
Assessment of the resilience of pedestrian roads based on image deep learning models

Published: February 2022

Currently, the evaluation of pedestrian paths is very time consuming. Additionally, disabled pedestrians do not tend to change their routes, even if pedestrian conditions are poor, resulting in reduced convenience and safety. Therefore, it is important to identify and act on the statuses of pedestrian paths quickly. Therefore, this study aimed to identify and process the conditions of pedestrian paths quickly to achieve high resilience. A resilience triangle was calculated according to the discrimination automation to analyse the corresponding values. Pedestrian path discrimination automation applies convolutional neural networks and ‘you only look once’ analysis to identify the road surface conditions of walkways and the presence of obstacles. Quantitative analyses for the safety and economic problems associated with transportation vulnerabilities through discrimination algorithms using deep image learning were carried out. As a result of the analyses, it was possible to determine the extent of damage with 94% accuracy if only damaged sidewalk photographs are captured. When this result was applied in Seoul, the benefits of improving pedestrian paths were quantitatively calculated to be South Korean Won (KRW) 41.2 billion (1 KRW=US$0.00085). This study may secure pedestrian resilience and improve convenience in the current scenario of a rapidly ageing population.
Seguridad, autonomía e industria: el equipamiento médico en el Mercosur
Authors: Gil Luciana-Victoria
Published: February 2022

Este artículo tiene como objetivo analizar las características principales de la industria de equipamiento médico en el Mercosur, así como las medidas adoptadas respecto a ella a partir de la pandemia de COVID-19. Se parte de las discusiones teóricas sobre seguridad y autonomía sanitaria, para identificar el papel de la industria del equipamiento en ambos conceptos. Con base en ello, se analizan las características de dicha industria en Brasil y Argentina, así como las medidas vinculadas al sector que se anunciaron a consecuencia de la pandemia, tanto a escala nacional como, en menor medida, regional. Se utiliza una metodología cualitativa, basada en el análisis bibliográfico y documental de fuentes primarias y secundarias, y en entrevistas en profundidad. Se concluye que, aunque Brasil y Argentina han reconocido el valor de esta industria, la ausencia de una perspectiva regional para su desarrollo limita su capacidad de consolidarse como referencia de la seguridad y de la autonomía sanitaria en América Latina.
Abstract
This article aims to analyze the main characteristics of the medical equipment industry in MERCOSUR, as well as decisions on this industry adopted since the COVID-19 pandemic. It starts by referring to the main theoretical discussions on health security and autonomy, identifying the role of medical equipment in both concepts. Afterward, the main characteristics of the medical equipment industry in Brazil and Argentina are analyzed, as well as the decisions adopted on a national and regional level. With a qualitative methodology, this research is based on a review of primary and secondary sources, as well as in-depth interviews. It is concluded that, even if Brazil and Argentina did recognize a renewed value of this industry, the lack of a regional perspective limits its capability of becoming a relevant sector for health security and autonomy in Latin America.

Bu çalışmada, benzetim modeli ile veri üretmenin maliyetli olabileceği karmaşık yapıdaki problemler için benzetim modelinin yerine kullanılabilecek Kriging tabanlı bir meta-model önerilmektedir. Üniversal Kriging (ÜK) meta-modelinin drift fonksiyonu yapısının bilinmediği durumlar için önerilen bu yeni model yapısında, ÜK meta-modelinde drift fonksiyonu olarak kullanılan birinci ve ikinci dereceden regresyon modelleri yerine, kesirli değerler de alabilen değişkenlerin bir güç fonksiyonu kullanılmıştır. Kesirli Üniversal Kriging (KÜK) meta-modeli olarak adlandırılan bu meta modelin kestirim gücü deneysel analizlerle incelenmiştir. Geçerleme analizleri Ortalama Hata Kare (OHK) ve Enbüyük hata Kare (EHK) başarım ölçütlerine göre KÜK meta-modellerinin üstün kestirim gücüne sahip olduğunu ortaya koymuştur. Böylece, benzetim modelinin girdi-çıktı ilişkisinin karesel polinomial durumdan farklı ve daha yüksek dereceden etkilerini de içeren bir güç fonksiyonu ile ifade edilebilir olması durumunda, KÜK meta-modelleri yeni bir meta-model yaklaşımı olarak bu çalışmada önerilmektedir.

El arte, por su propia naturaleza, es una herramienta de transformación cultural que puede beneficiar de múltiples maneras a todos los colectivos sociales. La creación artística permite cuestionar aspectos de la sociedad y promover, por lo tanto, una concienciación colectiva e inclusiva, que aporte valores igualitarios que permitan afrontar los retos actuales de la Agenda 2030 para el desarrollo sostenible, como son la conciencia de la ecología, las desigualdades sociales, el diseño de nuestras ciudades, el hambre o la violencia machista y, por supuesto, cambiar actitudes y comportamientos.El fomento de la creatividad, el desarrollo del pensamiento crítico, el diálogo y el trabajo colaborativo forman parte de nuestro cuaderno de bitácora para cumplimentar nuestra investigación en poéticas liminales en el mundo contemporáneo, abordadas desde la creación, la formación y el compromiso social. El libro-arte y la pintura mural son dos ejemplos de prácticas artísticas colaborativas utilizadas como recursos de empoderamiento de colectivos vulnerables.
Promoting Social Media Engagement Via Branded Content Communication: A Fashion Brands Study on Instagram
Authors: Castillo-Abdul Bárbara , Pérez-Escoda Ana , Núñez-Barriopedro Estela
Published: February 2022

Social networks have become crucial communication channels for brands through awareness, engagement, and word of mouth. Instagram is firmly positioned as a direct gateway between brands and consumers, as it became the fifth most-used social network globally in 2021. As such, branded content is expected to increase the brand’s likability, by capturing the interest and attention of the consumer, which could differ depending on what social media platform is used. This study aims to analyze whether there is a relationship between the branded content published on the Instagram profile of luxury brands (Manolo Blahnik and Loewe) and the interactions of and with its followers, focusing on branded content communication associated to industrial, social responsibility, and commercial issues. A correlational study is presented using a quantitative methodology to test the hypotheses through an ANOVA analysis. The results show which type of content is more productive on Instagram’s social network profile, helping diffusion of the firm, as it provokes more reactions from followers when using branded content related to social responsibility. It is also worth noting the extent of the interactions that branded content shows within the brand, whose influence is detected not in averages but in reach. The study’s conclusions allow us to affirm that branded content directly impacts brand reputation, generating positive engagement in all the cases analyzed. The study contributes to a better understanding of the branded content effect on consumers.
Immigrant Influencers on TikTok: Diverse Microcelebrity Profiles and Algorithmic (In)Visibility
Authors: Jaramillo-Dent Daniela , Contreras-Pulido Paloma , Pérez-Rodríguez Amor
Published: February 2022

Internet celebrity has become a phenomenon of great interest for scholars in the last few years. This is partly due to its impact in contemporary media ecosystems, and its influence in political, social, cultural, and commercial behaviors around the world. Meanwhile, some segments of the population continue to be marginalized by sociotechnical configurations that perpetuate structures of dominance in the digital sphere and on social media platforms. This is the case of immigrants, who often face diverse digital, symbolic, and physical borders that neglect their voice and agency. Thus, the present study aims to explore the creative practices of immigrant tiktokers who have achieved a significant following on this platform. Using a case study approach, we explore four immigrant creator profiles with a following of 17,000 to 500,000 through in-depth interviews and a multimodal content analysis of 252 of their videos to delve into their platformed practices on TikTok. The participants are Latin American immigrant creators living in the US and Spain, identified as part of a larger study on the uses of TikTok by Latinx immigrants in these two countries exploring 53 immigrant creator profiles with more than 10,000 followers. Their practices related to algorithmic (in)visibility, and their unfolding identities including their digital, creative, political, activist, cultural, and national personas are noteworthy, and suggest unique pathways to reclaim agency through social media influence and construct multi-dimensional microcelebrity identities beyond migratory status.
Actually Existing Commons: Using the Commons to Reclaim the City
Authors: Newton Caroline , Rocco Roberto
Published: February 2022

In Paraisópolis, a slum in São Paulo (Brazil) housing over 100.000 inhabitants, the Covid crisis seemed to have less of a death toll (0,0217%) than in other areas of the city (an average of 0,0652% as of May 2020); or at least it did at first. The sense of community in the area is strong, leading to many community initiatives and organisations to rise to the challenge of combating the pandemic with little help from the authorities. The community’s initial efficient response to the Covid crisis relied heavily on self‐reliance and self‐organization to mobilise common resources. Despite their later failure in containing the virus, the community’s response to the pandemic is exemplary of a well‐known phenomenon: how communities are able to mobilise the commons to create general welfare. The commons concept is used in this contribution to help us better understand slum governance and the power and limitations of community reliance. At the same time, we aim to refine our understanding of the commons as a contentious category rooted in agonistic relationships instead of the romanticised leftist social imaginary that views the commons as purely anti‐capitalist. Thus, we explicitly argue for a view of the commons and commoning that transcends the narrow “Leftist imaginary” of the commons as egalitarian, inclusive, anti‐capitalist, horizontal, and as expressions of sharing (and caring), and instead views the commons as embedded in everyday realities, where commoning practices emerge as practises that support the reproduction of (social) life.
Concept Space of Headings (on the Material of Media Texts on the Topic of COVID-19)
Authors:   Taras Shevchenko national University of Kyiv, Marynenko Iryna , Shumarova Nataliya ,   Taras Shevchenko national University of Kyiv
Published: February 2022

Objective: The objective of this article is to build up the concept field of media texts’ headings referring to COVID-19 in their axiological variability. The analysis of concept space is based both on the principles of frequency of use of tokens and nominal word combinations, which reflect the development of events related to the pandemic, and on the evaluative division of headings which have neutral, positive or negative connotations. Methods: The main methods used in the study are contextual, syntagmatic and component analyses. Contextual analysis has given an opportunity to define the way and language means of presentation of the mentioned concept and its concept field. It also has made it possible to demonstrate the language means, which show the journalists’ intentions to present information to the audience, and has allowed to describe the interconnection between language interpretation character and variants of texts axiological paradigm. Syntagmatic analysis, particularly the analysis of left and right combination of words in the text, has identified subjective and objective relationships in the concept’s presentation, and the measure of saturation of the concept field with metaphoric and metonymic models, which are based on axiological principles. Component analysis has disclosed the peculiarities of structure of meaning of separate semantic variants of words. Results: In the result of studying 467 headings of articles in mass media the concept field COVID-19 was built. It was fulfilled on the base of presentation of a medical term as a concept. Definition of axiological variability of headings as the basis of seleection of lexical and grammatical means, and presentation of core concept in its subjective and objective relationships inside the sentence/ utterance were done. Conclusions: The language means of different evaluative segments of the field have common and varied functions. The commonness is in informing the population about development of events and the difference is in the ways of transferring the evaluative component of information. The grammatical means are more actively used to actualize their semantic and stylistic potential in the headings with negative and partially positive content.
A study of heat transfer enhancement for electronic packaging
Authors:   , Gingrich William K. , Cho Young I.
Published: February 2022

The fluid dynamic and heat transfer behavior of laminar non-Newtonian flow through non-circular ducts is of special interest because of their wide range of potential application in compact heat exchangers and in electronics cooling. The objectives of the present study were (1) to investigate the heat transfer characteristics for laminar forced convection of inelastic non-Newtonian fluids in a nonuniformly heated rectangular duct where the flow is hydrodynamically developed but thermally developing and (2) to investigate the influence of variable viscosity of temperature-dependent fluids on the laminar heat transfer and friction factors in a 2:1 rectangular duct. The governing equations were solved by a finite volume method. Second-order accurate differencing schemes were employed for both the diffusion and convective terms. The effects of shear thinning, given by the Carreau equation, and the viscous dissipation, characterized by the Brinkman number, were examined via the friction factor, the Nusselt number, and the bulk fluid temperature. The results indicated that when viscous dissipation was present, the heat transfer from the heated surface of the duct was greatly enhanced with increased shear thinning of the fluid while the rate of increase of the bulk fluid temperature significantly decreased with axial distance. Consequently, the use of a shear-thinning non-Newtonian fluid for heat transfer enhancement appeared to be a very promising concept that is worthy of further study. The present numerical results of local Nusselt numbers for oil (i.e., a temperature-dependent viscosity fluid) showed 70-80% enhancement over those of a constant property fluid and 40-50% enhancement over water, and gave excellent agreement with recent experimental results. The heat transfer enhancement from the heated top wall was due to an increased velocity gradient near the wall. A new correlation for local Nusselt numbers in the 2:1 rectangular duct was proposed which covered both thermally developing and thermally fully developed regions. Consequently, a temperature-dependent viscous fluid with a non-circular duct was proposed to be used in the design of a liquid cooling module for the computer industry.
