Authors: Karan Arnab Kanti , Sahoo Dipankar , Sen Sudipta , Manik N. B.
Published: August 2022

One of the most crucial variables to consider while analysing the current conduction process in the metal organic Schottky contact is the Richardson constant. However, there aren't many publications on the determination of the useful Richardson constant for Fruit dyes. For two different
Fruit dyes, Carmoisine, and Tartrazine, we have determined the values of the effective Richardson constant in this work. By using the spin coating method, a thin organic layer of these natural colours was sandwiched between a copper plate and a piece of glass that had been coated in indium
tin oxide. The current-voltage-temperature response of the cells was examined at a temperature range of 303K to 333K. The estimated effective Richardson constants for these dyes are 95.09 x 10-3 A/cm2K2 and 44.35 x 10-3 A/cm2K2
for CS and TZ dye respectively, which are different from the typical value of 120 A/cm2K2. We can analyse several electrical properties for these natural dyes with the aid of these values.

Reaction of passion fruit species to Rotylenchulus reniformis and Meloidogyne incognita
Authors: Silva Aline Mayara Gonçalves Barros , Inomoto Mário Massayuki
Published: August 2022

Abstract Passion fruit (Passiflora spp.) yield is limited by several factors, including soil pathogens, such as Rotylenchulus reniformis (the reniform nematode) and Meloidogyne incognita (the Southern root-knot nematode). Understanding the behavior of different cultivars, within different species of passion fruit could be important asset to the search for sources of resistance, and therefore for the effective management of phytonematodes. Three trials were carried out in greenhouse to evaluate the resistance/susceptibility of different passion fruit species to R. reniformis and M. incognita. For R. reniformis, cultivars from two species were tested: Passiflora edulis f. flavicarpa (‘BRS Sol do Cerrado’, ‘BRS Rubi do Cerrado’ and ‘BRS Gigante Amarelo’) and Passiflora cincinnata (‘BRS Sertão Forte’). Regarding M. incognita, all the cultivars above were evaluated, with the addition of Passiflora setacea (‘BRS Pérola do Cerrado’). The results showed that all tested cultivars were susceptible to the reniform nematode. Conversely, all tested cultivars were immune to root-knot nematode, although exhibiting root galling. Therefore, it is emphasizes the relevance of reniform nematode to passion fruit crops.
RESISTÊNCIA POLÍTICA SEM FOGO AMIGO: POR UMA IDEOLOGIA LINGUÍSTICA DAS MISTURAS EM NOSSA REVOLTA
Authors: Oliveira Raquel Souza de , Fabrício Branca Falabella
Published: August 2022

RESUMO Testemunhamos, na atualidade, a invasão da cultura beligerante em diversas esferas da vida social, inclusive, na política. Com o populismo de direita se alastrando em escala mundial, um olhar atento à maneira como a linguagem está sendo operacionalizada por líderes políticos e seus/suas apoiadores/as se faz necessário (HODGES, 2020). O mesmo pode ser afirmado em relação às crenças linguísticas que orientam as nossas interpretações sobre as formas e os usos das línguas e nossos modos de acionar resistência política. Neste trabalho, investigamos três tuítes de críticas direcionadas às performances discursivas de Abraham Weintraub, ex-Ministro da Educação do governo de Jair Bolsonaro, quando a norma padrão da língua portuguesa foi por ele violada. Visamos investigar as ideologias linguísticas que guiam tais críticas, avaliando os efeitos que produzem nos projetos políticos interessados em defender os direitos de grupos sociais marginalizados. Para nossas análises, utilizamos os construtos teórico-analíticos de iconização, recursividade fractal e apagamento (GAL & IRVINE, 2019). Os resultados do estudo indicam que modos de resistência orientados por ideologias linguísticas que defendem um ideal puro de língua endossam sentidos negativos associados aos recursos linguísticos populares e, por extensão, às categorias sociais dos/as excluídos/as. Defendemos as ideologias linguísticas das misturas (PINTO, 2013; FABRÍCIO & MOITA LOPES, 2019) como um caminho possível para pensarmos práticas de resistência política que sejam, de fato, comprometidas com pautas inclusivas e de justiça social.
SENTIDOS EM MOVIMENTO E TRABALHO DO EQUÍVOCO: UMA LEITURA DISCURSIVA DA PROPOSTA CURRICULAR NACIONAL PARA A OFERTA DE EDUCAÇÃO PLURILÍNGUE
Authors: Grigoletto Marisa , Fortes Laura
Published: August 2022

RESUMO Historicamente, as diversas modalidades de ensino bilíngue no Brasil não têm figurado em documentações político-educacionais regulamentadoras. Entretanto, em 2020, a proposição das Diretrizes Curriculares Nacionais para a oferta de Educação Plurilíngue, no âmbito do Conselho Nacional de Educação, pode ser compreendida como um instrumento de política linguística que visa suprir essa falta. Realizamos, neste artigo, uma análise discursiva desse documento, a partir de duas categorias: a produção de um equívoco e o efeito de (in)determinação em processos de designação. Faz parte do processo discursivo que subjaz à textualidade do documento a mobilização da memória do silenciamento de outras línguas presentes no território brasileiro, no processo de institucionalização do português como língua nacional, e o confronto com essa memória e imagem de país monolíngue. Levando em conta esse imaginário e o gesto político do documento na tentativa de abarcar situações muito distintas de ensino bilíngue (português + outra língua), postulamos que um equívoco atravessa a textualidade do documento, no tocante ao significante “educação bilíngue” ou “educação plurilíngue”, produzindo um efeito de (in)determinação na materialidade linguística. Concluímos que o equívoco indicia a contradição ao propor a homogeneização de situações distintas de ensino bilíngue e sustenta o efeito de confronto entre a indeterminação linguística (a legislação proposta pretende abarcar a educação em toda e qualquer língua falada no território nacional, além das línguas estrangeiras de prestígio) e a determinação discursiva, que faz incidir o foco da educação bilíngue sobre as línguas estrangeiras de prestígio.
Cross-sectional and longitudinal method for describing growth curve of rabbits
Authors: Fernandes F.A. , Silva M.A.J.G. , Silva W.D. , Fernandes T.J. , Muniz J.A.
Published: August 2022

ABSTRACT Rabbit farming is an activity with high growth potential due to its easy handling, high prolificacy, low polluting impact, and easy adaptability to family farming systems, producing meat of high biological value. Therefore, the aim of this work was to evaluate, using von Bertalanffy's nonlinear model, growth curves of weight as a function of age in ‘Flemish Giant Rabbits’ and ‘New Zealand White’ crossbred rabbits. Two different data collections were used: the longitudinal method and the cross-sectional method. The experiment was carried out at the Federal University of Lavras, located in the municipality of Lavras, Minas Gerais, Brazil, where 10 crossbred rabbits were evaluated, and animals were weighed from 0 to 150 days of age. Both methods proved to be adequate to describe the development of rabbits and the cross-sectional method proved to be an adequate alternative to obtention of growth curves, saving time in data collection and showing consistent estimates.

Published: August 2022

ABSTRACT This study aimed to determine the psychometric properties and clinical use of the Brazilian version of the Canine Brief Pain Inventory (CBPI) in dogs with hip dysplasia (HD). Forty-three dogs with HD and 16 clinically normal dogs were enrolled. The HD dogs were treated daily with 4.4mg/kg carprofen (GT = 21) or placebo (GP = 19), for four weeks. Owners completed the CBPI at two weeks (W-2) and immediately before the start of the treatment (W0), two (W2) and four (W4) weeks during treatment, and two weeks (W6) after the end of treatment. The internal structure was accessed, and the Cronbach’s alpha coefficient was 0.97, indicating the high internal consistency of the instrument. Principal Component Analysis (PCA) suggested the retention of one component, which accounted for 78% of the variability. The ROC curve analysis concluded that the score 3 has an excellent performance to discriminate between normal and possible HD dogs (AUC of 0.973). There was no difference between dogs treated with carprofen versus placebo. The instrument in Portuguese showed construct and criterion validity and reliability to be used in dogs with HD.

ABSTRACT It is known that there is a close relationship between pellet feed size and fish growth. However, the magnitude of this relationship regarding an animals’ feed efficiency is not yet clear. Therefore, the present study conducted at the Virginia Tech - Virginia Seafood Agricultural Research and Extension Center (USA), investigated the effects of three different pellet feed sizes, 1.7mm (EP.1), 2.3 mm (EP.2) and 3.1 mm (EP.3), on the growth of Cobia (Rachycentron canadum) in a recirculating aquaculture system (RAS). Animals were farmed for 55 days in 77.5-liter tanks (6 fish with an initial density of 3.78 g L⁻¹) weighing approximately 41.83±1.24g. The results showed that during the 8-week culture period, there were no significant differences between the animal’s final weight over the different pellet feed sizes (EP.1 - 952.5±40.7g; EP.2 - 1014.5±26.6g; EP.3 - 1030.0±54.8g). However, biomass gain showed significant differences (EP.1 - 704.0±34+.3g; EP.2 - 763.0±27.8g; EP.3 -776.5±51.9g). Consequently, significant differences were also found in the feed conversion factors.

ABSTRACT Between October 2016 and October 2017, 63 feline uroliths were analyzed at Universidade Federal de Goiás (UFG) by using both chemical analysis and energy dispersive spectroscopy (EDS). The most frequent mineral type found was struvite (53.9%), followed by urate (39.7%), calcium oxalate (30.1%) and calcium phosphate (25.3%). Calculus containing xanthine, cystine and silica were not observed. Uroliths classified as simple, comprised a total of 34/63. Amongst the 42 animals present in the study, 26 were male and 16 were female. Pure breed animals comprised 14.4% of the total, and the breeds observed within the study were the Persian, Himalayan, Siamese, and Angora. Cats between 25-72 months old were more frequently diagnosed with uroliths. The clinical signs varied between systemic and urinary signs and the most found were anorexia, vomiting, hematuria and dysuria. All patients were either spayed or neutered and 34 patients had no outdoor access. Familial information was unknown in almost 100% of the cases. The results observed in the present study serve as a basis for future comparisons related to the epidemiology of urinary lithiasis in Brazil, especially for the feline species.

Published: August 2022

ABSTRACT The objective of the present work was to evaluate the performance of a compartmentalized anaerobic reactor (CAR) followed by anaerobic filter in real scale, effluent treatment from fish fridge processing. The work was developed in a fish fridge located in the south of the state of Minas Gerais, which has an effluent treatment plant composed of static screen, grease removal device, CAR reactor and anaerobic filter. The monitoring happened trough physical-chemical parameters of fluids and effluents from all sampling points of the plant biweekly. The parameters evaluated were temperature, pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), volatile suspended solids (VSS), volatile fatty acids (VFA) and alkalinity. Operational problems found in the primary treatment were not limiting for the system performance, which managed to meet the parameters of environmental legislation in Minas Gerais according to the efficiency of removal of COD, BOD and VSS from wastewater from fish processing.
Development of high strength recycled aggregate concrete-composite effects of fly ash, silica fume and rice husk ash as pozzolans

The world today has started facing bigger problems related to the concrete industry, especially with concrete becoming the most extensively used construction material in the world. At a time like this, where more eco-friendly substitutions are stringent, it calls for a more comprehensive approach in producing recycled concrete from recycled concrete aggregates (RCA). This study is an extension to previous studies involving composite utilization of pozzolans in treating RCA. It investigates on the possibility of using rice husk ash (RHA) along with other pozzolans as a cement replacement, in both stages of aggregate treatment and concrete production. It was observed that through this treatment, aggregate specific gravity was increased to a value of 2.37 which was earlier 2.18 for untreated RCA, 26% and 59% reductions were obtained for water absorption and porosity of aggregates, respectively. Further the concrete which contained RHA in both stages, attained a high strength of 55.4 MPa, even surpassing the control mix containing natural aggregates. The same mix resulted a 12% increase in its surface resistivity. Rapid Chloride Permeability Test (RCPT) and water permeability results also showed substantial improvements when compared to the reference RCA mix. Similar to previous studies involving composite use of pozzolans, improvements in the microstructure of both the aggregates and concrete through the use of RHA resulted in the amelioration of both mechanical and durability properties of concrete. This evidently indicates the possibility of achieving high strengths, even with the use of RCA derived from parent concretes of lower grades.
Expansion potential of skin grafts with novel rotating-triangle-shaped auxetic incisions
Authors: Gupta Vivek , Gupta Shubham , Chanda Arnab
Published: August 2022

Millions of burn injuries are reported every year, with severe cases needing skin graft implantation. To date, the highest achievable expansion produced by split-thickness skin grafting has been reported to be just three times, which is insufficient for covering large burn sites with limited donor site skin. In this work, the authors studied the expansion potential of skin grafts with rotating-triangle (RT)-shaped auxetic incision patterns, which are known to exhibit a highly negative Poisson’s effect. Ten two-layer skin graft models with RT angles varying from 0 to 135° were developed and tested under uniaxial and biaxial tensile loads. Poisson’s effect, meshing ratios (MRs) and induced stresses were quantified across all models and loads up to the ultimate tensile stress. Very high expansions (MR > 45), varying widely across uniaxial and biaxial loads and without rupture, were observed for low RT angles. However, for RT angles greater than 45°, the expansions significantly decreased, with the lowest MR reported at 135°. Beyond an RT angle of 90°, the induced stresses were very high, with potential for skin rupture. Such expansion potentials and stress estimations with skin grafts have not been reported previously and would be indispensable for initiating groundbreaking advances in burn surgery research.
Mapping Barcelona’s Cultural Event Landscape: Geographies and Typologies
Authors: Colombo Alba , Luchtan Michael , Oliver-Grasiot Esther
Published: August 2022

In recent years, cultural events have proliferated in many European cities, incorporating not only local celebrations, but also cultural industry festivals and celebrations from diverse parts of the world. The use of spaces by these cultural events generates tension especially when different celebrations share the same locations. This chapter focuses on Barcelona, a city with a high population density and limited space where different interests include commerce, tourism and the need for social inclusion converge. The use of public spaces for events is managed by the municipal administration who try to generate equilibrium, but pressure over the use of those spaces is apparent from a close analysis of the quantity and the types of events that are programmed. This chapter identifies different typologies and explores the existing geographical distribution patterns of more than 300 cultural events. The background to this study lies in the intersection of planned events and urban public space. Our analysis of where an event takes place is rooted in the phenomenological understanding that urban public space is a process more than a physical location, a resource and an intersubjective reality that encompasses social rhythms, the public realm, and collective patterns of movement within an inhabited space. Quantitative event data combined with data from geographical information systems, shines a light on the distribution of cultural events throughout the city. Conclusions highlight the relevance of observing events distribution by typologies, as it illustrates centralisation and decentralisation, diverse uses of space, and highlights tensions and inequalities.
The Contested Role of Events in Public Squares: The Case of George Square, Glasgow
Authors: McGillivray David , Guillard Séverin , McPherson Gayle
Published: August 2022

Public squares have played an important historical role in urban life; they are designed to accommodate a range of civic activities, including hosting markets, military events, protests and commemorative occasions. More recently, they have been used as venues for a wide variety of both civic and commercial sporting and cultural events, as they can showcase the important attributes of a city to a watching global audience. However, the use of civic squares as event venues can lead to access restrictions, changes in public space management and concern over the publicness of these spaces. In this chapter, we outline the role festivals and events have played in the design and use of urban squares, historically and in the present. We then introduce the Glasgow-wide conversation to discuss the future of Glasgow’s George Square, and the observational and interview-based fieldwork we carried out during this process. We present the results of our investigations with a specific focus on discussions dedicated to the issue of events. We explore what this process revealed about Glasgow citizens’ views on the role of events in the future of the square, highlighting tensions between institutional actors and citizens about its purpose and use and the sort of events which should be hosted there. We conclude by arguing that the city-wide participatory process for this square revealed two dimensions of the contested geographies of festivals in the city: the contested role of events in public squares, and the contested voices of urban residents about public space.
The Publicness of Local Libraries: Insights From Local Libraries Turned Festival Venues in Dublin
Authors: Quinn Bernadette , Ryan Theresa
Published: August 2022

In an increasingly digital age public libraries have had to adapt to rapid changes in how information is produced, disseminated and consumed. This has led to questions about whether their physical presence matters any longer. In addition, they have been subjected to public funding cuts which seem likely to be exacerbated by the Covid-19 pandemic as demands on the public purse intensify. In terms of governance, as with other public spaces, there are signs of a move away from direct state involvement to arrangements involving a range of social actors. Developments like this which see the state reduce its oversight and involvement with public spaces have generally been interpreted negatively. In this context, Capillé (2017, 409) noted the importance of investigating the ‘publicness of public libraries and their value for society’. This chapter reports the findings of a study investigating the kinds of publicness that libraries foster. Empirically, it used a qualitative open-ended survey tool to gather data from people attending Dublin Festival of History events at six local libraries. The findings yield insight into people’s library usage, their understanding of the local library as a public space and the role that festivals and events play in opening it up to wider use. While the libraries studied create public spaces where groups of like-minded people can easily gather, reproduce shared meanings and generally feel included, they are not engaging for everyone. Study participants felt that libraries are under-valued and that barriers to accessing the public space of the local library are very real.
Longevity and Reinvention: Venetianization and the Biennale
Authors: Gold John R. , Gold Margaret M.
Published: August 2022

The Venice Biennale is the world's first biennial art exhibition. It was founded in 1895 as a way for Venice to put itself on the Italian festival map, to generate tourism, and to boost the contemporary cultural sector in a city with a strong tradition in classical art. The Biennale has adapted and evolved into a portfolio of 7 international exhibitions. Today three of these – the Art Biennale, the Architectural Biennale and the Film Festival – are global players in their respective fields. At the same time, the festival has also impacted geographically on the city. Beginning by utilising the Giardini gardens in the east of the city, it then spread to the redundant shipyards of the Arsenale in the 1980s, where it became a driving force for regeneration. More recently, it has diffused outwards into the wider city as national pavilions and collateral events established themselves in suitable buildings after 1995. Described as the Venetization of the festival, this geographical spread of the Biennale from its original exhibition ground has rooted the biennale in the fabric of the city in new ways. This chapter looks at the origins of the festival and its current relationship to the city, highlighting the ways in which the festival has adapted to internal and external pressures for change while keeping its model of national pavilions, by which countries display their art. Initially a pragmatic solution to diversifying the exhibition, this was later interpreted as a straightjacket and an imperial anachronism, but has nevertheless endured as a feature of the Arts and Architectural Biennales. Seen as a means of promoting tourism, the Biennale is now ironically seen as an antidote to overtourism and mass cultural tourism by tempting visitors away from the crowded centre to explore the city beyond.
Limerick City Stories: The European Capital of Culture Bid Process and Narratives of Place
Authors: NicGhabhann Niamh , Ryan Annmarie , Kinsella Stephen
Published: August 2022

This chapter explores the European Capital of Culture programme, with a specific focus on the bidding period as a period of opportunity and change. Building on previous research by the authors, the chapter explores the dynamics of festivity and city narratives in relation to Limerick’s bid to become European Capital of Culture in 2020. Although the bid was ultimately unsuccessful, the bidding process can be seen as a period during which multiple diverse stakeholders came together to think about the role of culture in the city and region, and the future of the area's unique cultural identity. While the interaction between Capital of Culture projects and urban regeneration has been explored in relation to other cities – Glasgow and Liverpool in particular – this chapter turns attention to the process of the bid preparation, examining issues of narrative and perceived potential. In particular, the essay unpacks the complexities around, and difficulties with, narratives of transformation which position the festive year as an opportunity to redefine the city on an international stage. This emphasis on redefinition and change was evident in the opening paragraphs of the Limerick 2020 bid book, which included the statements that ‘Limerick had been a non-place in Europe for a long time’, and that 'we are ready for a new Limerick’. This chapter identifies, locates, and explores the articulation and circulation of these narratives of city transformation: within the documents produced by the Limerick 2020 bid team; in media coverage of the bid process; and in urban interventions where the Limerick 2020 logos and artworks were embedded in the urban fabric. In considering these narratives in the broader context of Limerick's history, it examines the impact of the time-limited and pressurised context of bidding on stakeholder relationships in sustainable cultural partnerships.
Unravelling the Complex Nature of Events-Focused Policy: A Framework to Aid Understanding
Authors: Rust Elaine
Published: August 2022

Local policymakers are constantly developing strategies aimed at creating a vibrant atmosphere for their town centres. This is significant when set alongside the persistent narratives of failing retail, increased challenges posed by changing consumer demand and uncertainty over the consequences of the UK’s departure from the European Union. Events-focused policies are seen to offer this yearned for vibrancy, as well as potential to increase the economic fortune of host towns’ permanent retail and service provision. This policy becomes a more attractive proposition to small towns when successes are widely publicised in the media or are seen to be used as a tool for tourist promotion. While evidence exists suggesting that regular events, such as weekly markets, result in increased footfall, there is little existing research that either explores whether the same applies to less regular events (for example, monthly or annual) or whether an increase in footfall translates into the desired increase in economic activity. With growing pressure on local authority finances, policymakers need to be fully aware of the consequences of implementing such a strategy, thus such research is overdue. This chapter adopts mixed methods to explore the ways that a local authority in the south of England implements a cultural events programme by examining one event in each of the authority’s three main urban centres. Results of an economic impact assessment suggest that the ratio of expenditure at event trader stalls to host town provision varies and is dependent upon the type of event. Findings from the qualitative component analysis determine other less tangible, yet equally important, benefits and consequences of these events on the local community and businesses. Since these findings carry major implications for local authority decision makers, an initial framework for understanding the impact of such events is proposed.
Festival City Futures: Reflections and Conclusions
Authors: Quinn Bernadette , Smith Andrew , Osborn Guy
Published: August 2022

This concluding chapter reflects on some of the key themes highlighted by previous chapters, but it also aims to look forward by examining how city festivals and festival cities may develop in the future. The chapter explores one of the most important dimensions of the book – the ways festivals and events might help to produce more inclusive public spaces. The authors explore whether the social and cultural value of festivals may be (re)prioritised over the economic agenda which has dominated in recent years. The contested nature of city festivals and urban festive spaces is also discussed at length, and the chapter also covers the importance of analyses that can capture the affective and sensorial effects of urban festivity. This provides the basis for a wider review of the methods employed by the authors of the chapters that feature in the book. Inevitably, given the timing of the book, there is also an attempt to highlight the implications of the Coronavirus pandemic, and the ways that urban festivity may be affected in the medium and longer terms. The chapter concludes by summarising the contribution of the book, and by making some suggestions for future research that would help us to better understand the relationships between festivals, public spaces and social inclusion.

Published: August 2022

Objetivo. En este artículo se presenta la investigación realizada sobre configuración del rol paterno sin la presencia de la madre en dos tipologías de hogar. Metodología. La investigación es descriptiva, con un enfoque fenomenológico-hermenéutico, en el cual se buscó analizar la configuración del rol paterno sin la presencia de la madre en hogar monoparental y extenso familiar. Resultados y conclusión. En la investigación se identificaron dos narrativas de la configuración del rol paterno: una surge desde la gestación y la otra al hacerse cargo del hijo sin la presencia de la madre. En ambas narrativas se hicieron evidentes factores potenciadores que facilitan a los hombres asumir el cuidado de sus hijos. Añadido a esto, el cuidado es un elemento transversal en la configuración del rol paterno, es relacional puesto que se genera en el vínculo y a la vez reafirma la paternidad. El cuidado es organizador de la vida del padre, lo moviliza a nuevas formas de relacionarse, transforma el rol y sus funciones, impulsando nuevas formas de ser y hacer en la vida del padre.

Objetivo. Identificar el tipo de relaciones que gestan las personas mayores que se quedan en contextos de alta migración. Metodología. Estudio etnográfico realizado en una localidad mexicana con índice de migración y envejecimiento alto. Resultados y conclusión. La red migrante principal de las personas mayores son los hijos; lo que lleva a que construyan redes a diferentes escalas: familiares, locales, regionales y trasnacionales, además del desarrollo de vínculos con seres vivos no humanos. Las dinámicas migratorias favorecen la conformación de redes comunitarias por parte de las personas mayores que se quedaron en sus localidades de origen, donde las familias nucleares se desdibujan y se convierten en familias extendidas en las que se incluyen las redes y vínculos generados a partir del proceso migratorio. Los patrones tradicionales de cuidado recíproco entre padres e hijos se reconfiguran y empiezan a ser asumidos por otras redes.

Introduction. It is important to identify racial/ethnic groups that may be less likely to achieve sufficient physical activity levels, and to address barriers to meeting physical activity requirements.
Methods. Cross-sectional data from the 2006-2015 National Health Interview Survey (NHIS) was used to compare self-reported sufficient physical activity among different racial/ethnic groups: non-Hispanic (NH) Whites, NH Blacks, NH Asians, and Hispanics. Sufficient physical activity was defined as ≥150 minutes per week of moderate-intensity physical activity, ≥75 minutes per week of vigorous-intensity physical activity, or ≥150 minutes per week of moderate and vigorous physical activity.
Results. The study sample consisted of 296,802 individuals, mean age ± standard error age 46.4 ± 0.10 years, 52% women, 70% NH White, 12% NH Black, 5% NH Asian, 14% Hispanic. The prevalence of sufficient physical activity in the overall population was 46%, while it was 48% among NH Whites, 39% among NH Blacks, 45% among NH Asians, and 40% among Hispanics. In multivariable-adjusted models (odds ratio; 95% confidence interval), NH Blacks (0.79; 0.64,0.97), NH Asians (0.72; 0.62,0.85) and Hispanics (0.71; 0.61,0.82) were significantly less likely to engage in sufficient physical activity compared with NH Whites. Older age, women, and low income were inversely associated with sufficient physical activity, while a college education or higher was directly associated with it.
Conclusions. NH Black, NH Asian, and Hispanic adults are less likely to engage in sufficient physical activity levels compared with NH Whites. It is important to address barriers to meeting physical activity thresholds to help achieve optimal cardiovascular health.
Ciudades, comunicación digital y pospandemia: de las smart cities al urbanismo de plataformas
Authors: R. Rossi Luis Sebastián
Published: August 2022

Este trabajo aborda la antigua relación entre ciudades y comunicación digital a la luz de las aceleradastransformaciones tanto en la emergencia social, económica y sanitaria del Covid-19 como en la pospandemia. Con el objetivo de advertir cambios significativos en la agenda de nuestro campo y sus relaciones con dimensiones y teorías urbanísticas, nos aproximaremos desde una estrategia de revisión de la literatura académica a tres instancias fundamentales. En primer lugar, atenderemos a las condiciones que han hecho posible comprender las realidades urbanas en vinculación con máquinas de información tanto através de aproximaciones morfológicas como en la historia concreta de las ciudades digitales a iniciosde nuestra centuria. A continuación, nos detendremos en las definiciones y en las críticas a las smartcities cuya fuerza se hace legible como marco interpretativo para muchas de las tecnologías digitales enlas ciudades de nuestra región y en el contexto particular de la crisis global. Finalmente, abordaremosel urbanismo de plataformas como perspectiva para indagar la proliferación y reconstrucción de espacios metropolitanos a través de la plataformización y de ecosistemas de aplicaciones. En estos aspectosdescubriremos posibles líneas y temáticas de investigación para nuestro campo que —si no esperarona la emergencia sanitaria para comenzar— guardan capacidad heurística para comprender y explicarlas futuras realidades de las ciudades iberoamericanas a la luz de las mutaciones derivadas de la nuevanormalización.
Generación del Bicentenario: movimientos juveniles contra el expresidente Merino
Authors: Muguerza Mario , Gonzales-García Carlos
Published: August 2022

Este artículo estudia, desde el universo de la identidad y los movimientos sociales, el protagonismo que tuvieron los jóvenes peruanos conocidos como la Generación del Bicentenario frente a la toma de posesión del entonces presidente de la República, Manuel Merino, en noviembre de 2020. En ese contexto de movimientos ciudadanos identificamos sus principales características generacionales, posturas ideológicas y modos de protesta. Asimismo, abordamos la forma en que se autodefinen para elaborar una aproximación conceptual respecto a sí mismos como un movimiento social. La investigación es de enfoque mixto y de nivel exploratorio. En este sentido, se aplicó una encuesta a 380 peruanos mayores de 18 años, la mayoría de ellos de la Generación Y y Z. Los resultados muestran un mayor activismo de las mujeres; una poca vinculación partidaria con las propuestas políticas tradicionales; y el uso de recursos como marchas, cacerolazos y redes sociales. Por otro lado, identificamos actos solidarios como la movilización de manifestantes en autos, donaciones a brigadas, colocación de carteles en las fachadas de sus hogares o utilización de instrumentos de música andina en la vía pública. Concluimos que la Generación del Bicentenario desmitifica el desinterés de jóvenes en asuntos políticos y se organiza para defender la democracia a través de dos tipos de manifestantes: pro-democracia y anti-corrupción.

Published: August 2022

Las acciones gubernamentales permiten dar soluciones a problemas de interés público con la finalidad de mejorar la calidad de vida de la población; con la creación de la ley de Fomento al cine nacional en el 2006, el país inició un cambio en la producción cinematográfica, el objetivo de este estudio es determinar la incidencia de las políticas públicas en la producción cinematográfica de Ecuador durante la década 2007-2017. La presente investigación es cualitativa con un enfoque exploratorio Los métodos utilizados son histórico-lógico y analítico-sintético. Se utilizó un muestreo no probabilístico intencional para la aplicación de encuestas a un grupo de 200 cineastas y productores audiovisuales. Como resultados se analizaron los impactos económico y productivo del cine a partir de las políticas públicas establecidas en el gobierno de Rafael Correa, se identificó la transformación estructural de la cinematografía a partir de la Ley de Fomento Cinematográfico, expedida en el 2006 y un año posterior la creación del Consejo Nacional de Cinematografía. La falta de inversión extranjera, la limitada aplicación de la Ley Orgánica de Cultura y la Ley de Comunicación han dejado el cine fuera de los temas prioritarios minimizando la creación, distribución y acceso equitativo a diferentes contenidos audiovisuales; sin embargo; a pesar estas brechas el cine ecuatoriano sigue caracterizándose por su creatividad, relato de entretenimiento y resistencia que todavía aguarda por un despunte.
Support for reducing inequality in the new Russia
Authors: Mareeva Svetlana , Slobodenyuk Ekaterina , Anikin Vasiliy
Published: August 2022

This paper addresses the issue of the interrelation between different types of social mobility and support for reducing income inequality in contemporary Russia. Drawing from the Russian subsets of the International Social Survey Programme’s (ISSP) surveys, we estimate how this support is differentiated across experienced and expected subjective mobility. Official statistics and empirical survey data widely confirm that the large-scale socioeconomic changes that took place in Russia during the 2000s brought an increase in living standards for most population groups and a more-than-twofold reduction in poverty. However, according to the ISSP data, demand for the government to reduce income differences is at its highest level since 1992. More than 90 per cent of Russians unequivocally perceive income gaps in the country as too high (the same as in the late 1990s) and unfair. We test the effects of actual and expected mobility, showing that, in contrast to the literature, including earlier studies on Russia, past mobility and expected medium-term mobility do not have any significant effect on levels of support for reducing income differences, and only the effect of short-term expectations can be seen. We argue that the effect of social mobility in Russia is limited by a widespread consensus across the population that preexisting inequalities in Russia are too high and unfair – a viewpoint based mostly not on the specifics of individual situations, including experienced or expected mobility, but on shared subjective norms and beliefs about inequality and their contrast with existing reality.
Giving (positive) meaning to downward and horizontal occupational mobility to maintain individual well-being
Authors: Žabko Oksana
Published: August 2022

This study addresses some limitations related to knowledge of the circumstances that contribute to perceptions of downward or horizontal occupational mobility as a positive experience, increasing work satisfaction, labour market security, and maintaining subjective well-being. In pursuing this objective, seven working-life biographies are examined that demonstrate causes of occupational mobility, the investment needed for transition and stabilisation, as well as attitudes towards the destination occupation. Although a sense of meaningful work helps individuals accept a reduced income, interviewees treat it as a transitional period, seeing a possibility for at least some increase in salary. Maintaining one’s original social networks while accepting a less qualified occupation also contributes to preserving individual well-being. These aspects are more pronounced in women’s life stories. A more ambiguous attitude can be seen in the experience of men who encountered occupational and financial decline. While decision-making awareness, confidence in one’s choice, and control of the process helps to stabilize potential frustration caused by decline, some isolation from previous networks appears in the keeping of distance, reducing contact intensity, or staying abroad for longer periods. Perhaps to regain their subjective sense of well-being, the former implements the principle of ‘discrete stages’ in their social life, a notion that reflects the situation of their working life.
Trans-cardiac perfusion of neonatal mice and immunofluorescence of the whole body v1
Authors: Pérez Arévalo Andrea
Published: August 2022

Whole animal perfusion is a well-established method that has been used for the past decades in multiple research fields. Particularly, it has been very important for the study of the brain. The rapid and uniform fixation of tissue is essential for the preservation of its integrity and the study of complex structures. For small tissue pieces submerging in formaldehyde solution oftentimes is sufficient to get a good fixation, larger tissues or organs with a more complicated structure present a greater difficulty. Here, we report the precise parameters to successfully perform trans-cardiac perfusion of neonatal mouse pups that allows a uniform fixation of the whole body for subsequent structural analysis and immunohistochemistry. In comparison to standard perfusion procedures of adult mice, changes in the pump velocity, the buffer volume and in the needle size lead to high quality fixation of neonatal mice pups. Further, we present a whole-body section staining, which results in a highly specific immunofluorescence signal suited for detailed analysis of multiple tissues or systems at the same time. Thus, our protocol provides a reproducible and reliable method for neonatal perfusion and staining that can rapidly be applied in any laboratory. It allows a high quality analysis of cellular structures and expression profiles at early developmental stages.
Protocol for In-silico Design, Docking and Molecular Dynamic Simulation of Antisense Oligonucleotides v1
Authors: Uttarkar Akshay
Published: August 2022

Insilico drug design has been a catalyst in developing novel chemicals, Phyto-actives, nanoparticles, and anti-sense oligonucleotides. A robust screening setup increases the chances of success of every project. In recent years, anti-sense oligonucleotides (ASO) have provided a major breakthrough in developing 10 ASO drugs that are FDA-approved. This prompts us to develop a protocol for ASO design, docking, and MD simulation studies. The protocol has been divided into 6 sub-sections inclusive of 30 steps. The tools used in the protocol are either open-source or academic free version. The protocol is developed and validated on GPU workstation using NVIDIA A100
Generation of stable cell lines via retroviral or lentiviral transduction v1
Authors: Fasimoye Rotimi
Published: August 2022

The ability to stably express a protein of interest in cells is critical to study its function. Here, we describe a protocol to generate stable cell lines using a retrovirus system that can be used for a variety of mouse and human cell lines. Our protocol includes the production of retroviruses encoding the transgene of interest in HEK293FT and the subsequent transduction of the cell line that is intended to stably express the protein of interest. The same protocol can also be used to generate stable cell lines using a lentivirus system. It should be noted that when using this method, the transgene of interest will be randomly integrated into the cell genome.
