Escala Intercultural de Concepções de Deficiência: Construção e Estudos Psicométricos
Authors: LEITE Lúcia Pereira , CARDOSO Hugo Ferrari , OLIVEIRA Taize de
Published: July 2021

RESUMO: Um mesmo instrumento pode ser adequado para distintas realidades, mas, para ele que avalie de fato concepções atreladas a um contexto cultural particular, é preciso compreender o fenômeno sob as lentes desse cenário. O objetivo deste artigo foi apresentar os resultados preliminares de validação e de confiabilidade da Escala Intercultural de Concepções de Deficiência (EICD) para a realidade brasileira. A EICD é um instrumento elaborado por uma equipe de distintos países (Brasil, Espanha e Portugal) e voltado para a avaliação de concepções de deficiência. Contou-se com a validação qualitativa (com base no conteúdo), por meio dos juízes nacionais e internacionais, e por verificação de componentes principais realizada por análise fatorial exploratória dos dados coletados com um grupo amostral brasileiro. A versão final contou com tradução e retradução para quatro diferentes línguas: espanhol (Cuba), catalão (Barcelona), castelhano (Sevilha) e português (Portugal). No que tange ao estudo fatorial para a realidade brasileira, a EICD ficou composta por 43 itens, distribuídos em três dimensões (Concepção Biológica, Concepção Social e Concepção Metafísica (Religiosa)). Estudos futuros serão necessários para o aprimoramento psicométrico do instrumento, tanto no contexto nacional quanto no internacional.

Authors: RODRIGUES Viviane , GONÇALVES Adriana Garcia
Published: July 2021

RESUMO: Pesquisas envolvendo o processo de escolarização da pessoa com Deficiência Intelectual (DI) são necessárias, visto que, em média, 45,6% das pessoas com DI são analfabetas no Brasil. Diante desse cenário, torna-se fundamental pensar no processo de alfabetização desses estudantes, especificamente em possibilidades que auxiliem práticas pedagógicas eficazes. Este artigo objetivou analisar a eficácia do Programa Computadorizado de Alfabetização de abordagem Fonovisuoarticulatória em três estudantes com DI, de 12 e 13 anos de idade, não alfabetizados que frequentavam uma escola especial. Para tanto, o estudo foi dividido em quatro etapas: I- Aplicação da avaliação de leitura e escrita; II- Aplicação do procedimento experimental, após avaliações e testes, utilizando o delineamento de Linha de Base Múltipla - a intervenção foi realizada individualmente em sessões de aproximadamente 50 minutos, três vezes por semana, durante quatro meses, e as informações foram anotadas na Folha de Registro; III- Reaplicação da avaliação de leitura e escrita; IV- Aplicação do Questionário de Validade Social. Os dados foram analisados considerando aspectos como o desempenho dos participantes, o monitoramento do processo de leitura e escrita e o número de acertos nas etapas de intervenção. Os resultados mostraram que os participantes aumentaram as respostas corretas após a introdução da intervenção com o programa quando foram apresentadas as atividades das vogais e das consoantes, uma vez que estiveram todas as sessões de intervenção acima da linha de base. O Questionário de Validade Social demonstrou a percepção da professora e da coordenadora pedagógica sobre a intervenção, relatando que puderam observar avanços dos participantes quanto ao processo de alfabetização.

Frequentist and Bayesian inference for gas exchanges of drip-irrigated bell pepper1
Authors: Santos Fernando André Silva , Rezende Roberto , Wenneck Gustavo Soares , Santi Danilo César , Saath Reni
Published: July 2021

ABSTRACT The water deficit or excess may cause undesirable changes in yield and physiological aspects of irrigated crops. Considering the analysis of experimental data, the use of classical statistical methods may not be sufficient to detect morphological and physiological effects resulting from the conditions employed, being interesting the use of new procedures, such as the Bayesian inference. This study aimed to evaluate the gas exchanges in the bell pepper crop under irrigation depths and different irrigation times, in a protected environment, by applying the parametric and Bayesian methods. The experiment was conducted in a completely randomized design, arranged in a 5 x 2 factorial scheme, with five irrigation depths (60, 80, 100, 120 and 140 % of the crop evapotranspiration) and two irrigation times (8 a.m. and 2 p.m.), with five replications. The stomatal conductance, transpiration rate, photosynthetic rate, intrinsic water-use efficiency, ratio between the photosynthetic rate and the transpiration rate, and total dry matter were evaluated. The gas exchanges were affected by water replacement depths, with little interference from the irrigation times. The linear regression models, according to the irrigation depths, for transpiration rate, stomatal conductance and total dry matter were significant for both the statistical methods, suggesting that the results are similar and even coincident, especially when a priori information are not provided in the Bayesian analysis. Differences in the photosynthetic rate were observed only with the Bayesian method, adjusting linear models according to the irrigation depths, in both the irrigation times.

ABSTRACT The correct deposition of spray along the canopy is important for the phytosanitary control in coffee plants; however, the structure of the plant makes this distribution difficult. This study aimed to evaluate the deposition of a tracer on leaves and fruits in coffee cultivation, with respect to the application rate and type of hydraulic nozzle, as well as the use of an electrostatic spraying system. A hydropneumatic sprayer was used, with hydraulic nozzles of empty conical jet of the series TVI (coarse droplets with air induction) or JA (fine droplets), at rates of 200 and 400 L ha-1. An electrostatic system, with SPE-2 nozzle and rate of 200 L ha-1, was also evaluated. The deposition of the tracer on leaves and fruits of the upper, middle and lower thirds of the trees, as well as the losses to the ground in the canopy projection, were quantified using spectrophotometry. The results indicated that the electrostatic application provides a greater deposition on leaves of the upper third than the hydropneumatic application, regardless of the application rate. The use of the TVI nozzle results in a greater deposition on the fruits of the middle third and a greater loss to the ground than the JA nozzle. Although an application rate of 400 L ha-1 results in a greater deposition on the fruits of the middle third than an application rate of 200 L ha-1, it also causes a greater loss to the ground.

Published: July 2021

ABSTRACT Irregularity or shortage of rainfall in semi-arid regions forces farmers to use low-quality water to irrigate crops. The present study aimed to assess the water-use efficiency and post-harvest quality of ‘Sugar Baby’ mini watermelon in response to different electrical conductivities of the nutrient solution [2.5 (control), 3.5, 4.5, 5.5 and 6.5 dS m-1], in a floating hydroponic system. The experimental design was completely randomized, with four replicates. The water consumption, production and water-use efficiency were evaluated, as well as qualitative and physico-chemical variables of the fruits. The total water consumption of the plants during the crop cycle varied between 43 (6.5 dS m-1) and 54 (2.5 dS m-1) L plant-1 among the treatments, with water-use efficiency of 0.031 kg L-1. The greatest reductions due to the nutrient solution salinity were observed for the rind thickness and fruit mass (8.80 and 5.69 %, respectively, per unit increase in dS m-1). The salinity of the nutrient solution did not influence the soluble solids content and fruit maturity index, but it had a negative effect on the pH and titratable acidity.

Published: July 2021

ABSTRACT An essential factor for the formation of a native orchid seed bank is the identification of the viability of stored seeds. This study aimed to determine a methodology for optimizing the tetrazolium test, in the identification of the viability of stored seeds of two Orchidaceae medicinal species native to the Brazilian Savanna. Seeds of Miltonia flavescens Lindl. and Schomburgkia crispa Lindl. were submitted to three pre-conditioning conditions: no soaking (control), sucrose solution or distilled water. The seeds were then submitted to a tetrazolium solution, with three types of conditioning: oven, water bath or ambient temperature. The M. flavescens seeds showed a germination of 86.91 %, with a higher percentage of viable seeds (62.32 %) when submitted to pre-conditioning with sucrose + oven conditioning. For S. crispa, the germination was 97.78 %, with a higher percentage of viable seeds for the control treatment + ambient temperature (89.49 %). These results suggest that specific protocols should be used to conduct the tetrazolium test in Orchidaceae. Moreover, when performed on a sample basis, the tetrazolium test should only be used to indicate the seed viability.

Published: July 2021

Resumo O objetivo deste trabalho foi analisar os argumentos empregados na condenação ou absolvição das mulheres acusadas de abortamento, especialmente os processos que foram suspensos. Analisamos sentenças e acórdãos referentes ao autoaborto (art. 124 do Código Penal) dos Tribunais de Justiça dos estados de São Paulo e de Minas Gerais. Como resultado do levantamento, constatamos a reiterada concessão da suspensão condicional do processo ou da pena, o que poderia ser considerado medida despenalizadora, por acarretar a extinção da punibilidade. No entanto, ante a aceitação e devido cumprimento das condições impostas pelo prazo fixado, o conteúdo das decisões de suspensão (de processo e de pena) explicita o caráter moral das sentenças, bem como a discriminação de gênero e a violência institucional. Assim, discute-se os fins da criminalização do abortamento e as consequências para o exercício pleno dos direitos sexuais e reprodutivos das mulheres.

Abstract Introduction: Monitoring water quality in mobile dialysis (MD) services, assessing critical points and characterizing the risks inherent in the process, is essential to avoid risks to the patient's health. This study evaluated the microbiological quality of water in the MD of 36 hospitals with intensive treatment in the city of Rio de Janeiro. Methods: 204 water samples were collected from the points of entry to the network (NET), post-osmosis (PO) and dialysis solution (DS). The samples were evaluated for heterotrophic bacteria count, pathogen search, presence of endotoxins and aluminum content. Results: Bacterial contamination at 3 collection points in 36 hospitals was 30% (32/108); 42% from DS, 31% from PO and 17% from NET, with the presence of Pseudomonas aeruginosa, Stenotrophomonas maltophilia , Burkholderia cepacia and Ralstonia pickettii in the 3 points. Endotoxin concentrations above 0.25 EU/mL occurred in 77% of the samples (17/22) analyzed in the PO. In the aluminum content, values above 0.01 mg/L were presented in 47% (7/15) of PO samples and 27% (4/15) of NET samples. There is no specific legislation for water used in the MD; therefore, the limits of the RDC of the National Health Surveillance Agency (Anvisa) 11/2014 were used; which regulates conventional hemodialysis services. Conclusion: The results highlight the importance of evaluating water quality in MD services to ensure patient safety and support the sanitary monitoring of this process as a healthcare promoter.

Abstract Cultivation conditions are determining factors that affect the quality of cut flowers. The objective of this study was to evaluate the vegetative growth, flowering and vase life of commercial gladiolus cultivars under different shading conditions in the Brazilian semi-arid region. Two cultivars of gladiolus (Jester and Rose Friendship) were grown under two conditions: full sun and 70% shade. Biometrics were evaluated 60 days after planting and the growth rate of the crop was evaluated at 15-30, 30-45 and 45-60 days for the variables: number of tillers, stem diameter, number of leaves and plant height. After 45 days, the fresh weight, dry weight and total relative water content of the area and root parts of the plants were evaluated. After the harvest, the stems were kept at a temperature of 22±3 °C and relative humidity (RH) of 60%. Visual assessment, pH of the solution, variation in the volume of water and loss of fresh mass were measured every two days. Cultivation with 70% shading resulted in greater accumulation of biomass in the aerial part of gladiolus plants, greater neck diameter and height. The Rose Friendship cultivar underwent a greater translocation of dry matter to the aerial part of the plants, resulting in greater height. On the other hand, the gladiolus stems from cultivation under full sun conditions resulted in longer vase life, 10 days under conservation conditions at 22±3 °C and RH 60%.

Justiça reprodutiva e gênero: desafios teórico-políticos acirrados pela pandemia de Covid-19 no Brasil
Authors: Brandão Elaine Reis , Cabral Cristiane da Silva
Published: July 2021

A partir de ações do poder público durante o enfrentamento da pandemia de Covid-19 no que tange aos direitos sexuais e reprodutivos, busca-se refletir sobre o descaso do Estado brasileiro em relação à saúde das mulheres, sobretudo as usuárias do Sistema Único de Saúde, descumprindo princípios assegurados constitucionalmente. A pandemia vem atingindo sobremaneira no país populações historicamente excluídas por diversos eixos de opressão e subalternização social. Sublinha-se o arrefecimento da assistência em saúde sexual e reprodutiva, que pode redundar em gravidezes imprevistas, abortos inseguros e mortes maternas, agravando condições sociais de vida de um grande contingente populacional. Argumenta-se que aportes teóricos oriundos dos estudos do feminismo negro, nomeadamente interseccionalidade e justiça reprodutiva, ao articularem os marcadores sociais da diferença ao princípio de justiça social, auxiliam-nos na compreensão dessas desigualdades sociais e na resistência coletiva ao desmonte das políticas de saúde.

Published: July 2021

Photoelectrocatalysis offers a way to generate hydrogen and oxygen from water under ambient light. Here, a series of hydrogen evolving photocatalysts based on a ruthenium(II) bipyridyl sensitiser covalently linked to platinum or palladium catalytic centres were adsorbed onto mesoporous nickel oxide and tested for hydrogen evolution in a photoelectrochemical half-cell. The electrolyte buffer was varied and certain catalysts performed better at pH 7 than pH 3 (for example, PC3 with photocurrent density = 8 μA cm–2), which is encouraging for coupling with an oxygen evolving photoanode in tandem water splitting devices. The molecular catalysts were surprisingly robust when integrated into devices, but the overall performance appears to be limited by rapid recombination at the photocatalyst|NiO interface. Our findings provide further insight towards basic design principles for hydrogen evolving photoelectrochemical systems and guidelines for further development.

Recalibrating Everyday Space: Using Section 24 of the South African Constitution to Resolve Contestation in the Urban and Spatial Environment
Authors: Coggin Thomas
Published: July 2021

Positioned as existing predominantly within a green agenda, the right to an environment (section 24 of the Constitution of the Republic of South Africa, 1996) presents numerous opportunities for rights-based interpretation in the "brown" urban and spatial environment. In this article I conduct such an exercise, focussing on both the right to freedom of movement (section 21 of the Constitution) and the right to the safety and security of the person (section 12 of the Constitution). I begin by drawing out the historical and contemporary spatial implications of both rights, drawing on empirical research that demonstrates how the enclosure of everyday space through gating practices and private securitisation in the South African city serves to extend spatial apartheid into the current day. A siloed interpretation of both rights, however, leads to an impasse between the two. Both rights are prima facie of an equal value in a constitutional setting.

To resolve this standoff, I argue for the use of the environmental right as a constitutional value. This is an underutilised right in the South African Constitution, and yet it holds much promise given how it seeks to protect the health and wellbeing of both present and future generations.

There are two benefits to employing the environmental right as a constitutional value. First, the environmental right situates both section 12 and section 21 in a symbiosis of individual claims to shared resources, in the process recalibrating the human ecology of the urban and spatial environment away from the centrality of dominant actors and towards a polycentricity of interests. In so doing, section 24 provides a fuller and more connected picture of both rights.

Second, the duty implicit in the environmental right reveals how to begin realising these rights on a wider scale that goes beyond individual injustices and towards community justice. I argue strongly that this duty exists on the state: left unattended to, everyday space becomes the preserve of those with the means – financial or otherwise – to shape space according to their own anti-public interests. In this regard, I present two instances of policy and legal choices available to the state that serve to undo contemporary experiences of spatial apartheid
South African infrastructure condition - an opinion survey for the SAICE Infrastructure Report Card
Authors: Rust F C , Wall K , Smit M A , Amod S
Published: July 2021

The South African Institution of Civil Engineering (SAICE) Infrastructure Report Cards of 2006, 2011 and 2017 reported that much of the South African infrastructure is in a poor condition. To augment the recent 2017 Report Card, a survey was, for the first time, conducted amongst SAICE members to obtain their opinion on the condition of infrastructure (in terms of a grading), the trend of the condition over time, as well as the reasons for the individual's grading. The 669 respondents indicated that, apart from a few exceptions such as national airports and the Gautrain, much of the infrastructure is in a poor state, which is very similar to the results obtained from the SAICE Report Card process. The results were also analysed per province and indicated that, in the opinion of respondents, specific provinces in particular are struggling with poor infrastructure. The main reasons given for the poor infrastructure were a lack of maintenance, lack of institutional capability, lack of sufficient funding and over-loading of infrastructure.
Prediction of California Bearing Ratio and compaction characteristics of Transvaal soils from indicator properties
Authors: Haupt F J , Netterberg F
Published: July 2021

A preliminary statistical analysis of 914 mostly Transvaal soils of average selected subgrade quality produced useful, highly statistically significant methods for the prediction of the maximum Proctor CBR and the Proctor compaction characteristics, as well as relationships between soaked and unsoaked CBR and between Proctor and MAASHO compaction characteristics. Because of the well-known poor reproducibilty of the CBR, as well as the indicator tests used, it is believed that the accuracy of the prediction methods is better than it appears from the large scatter of results. These methods do not replace CBR testing but supplement it by possibly reducing the number of expensive tests and providing a check on gross errors.

Host plant quality is determinant for herbivorous insects performance and survival. While on larval stages, insects select their host plants based on factors such as leaf nitrogen and water content, digestibility, and defences. Of great interest is the coevolutionary relationship between the Heliconiini insects and the Passiflora plants. In this study we experimentally evaluated Dryas iulia (Nymphalidae) larval preference to four sympatric Passiflora (Passifloraceae) and subsequently, the larval performance on the two most consumed species. We tested the hypothesis that D. iulia larvae prefer the Passiflora species with higher nutritional quality and lower defence, which supports the greatest larval performance. Dryas iulia larvae preferred P. misera (60.5% leaf consumption) over P. pohlii (28.9%), P. suberosa (15.5%), and P. edulis (not consumed). Passiflora misera presented the highest N concentration, third in water content, second in tector trichomes, and no glandular trichomes (only P. suberosa did). Nitrogen best explained D. iulia larvae leaf consumption; which further explains the greatest larval performance in P. misera than in P. suberosa: i.e. higher survival (23.1%), conversion efficiency of ingested food (32.8%), relative growth rate (14.8%), heavier pupae (15.2%), and lower relative consumption rate (13.8%). This study creates the opportunity to further investigate the Heliconiini-Passiflora system and showed that D. iulia larvae can assess and choose the host plant (even among sympatric species) that supports the greatest performance.

Marjinal devrimden önce, politik iktisat olarak anılan iktisat bilimi, psikolojik olgular hakkında yorumlarda bulunmuştur. Doğa bilimlerinde yaşanan gelişmeler çerçevesinde, iktisat mantıksal pozitivizmi ve matematiği başat hale getirerek teorilerini test etmeye çalışmış, bireyleri rasyonel ve faydacı ütopik aktörler olarak tanımlamıştır. Bilişsel devrimle birlikte, psikoloji bireyin karar alma sürecini araştırmayı mümkün kılmış ve bu gelişme, davranışsal iktisadın doğuşunu beraberinde getirmiştir. Bu çalışmada davranışsal iktisadın iki aşaması tarihsel olarak tartışılmakta, ardından epistemolojik ve metodolojik arka planı irdelenmektedir. Nihayetinde, Türkiye’de yürütülen davranışsal iktisat araştırmaları değerlendirilmektedir. Çalışma, Türkiye’deki araştırmacılara ve kurumlara ve davranışsal iktisadın gelişimine katkı sağlamayı amaçlamaktadır.

Enflasyon hedeflemesi politikası 1990’lı yıllardan itibaren ilk olarak Yeni Zelanda’da uygulanmaya başlanan daha sonra tüm Dünya’da hem gelişmiş hem de gelişmekte olan ülkelerde uygulanan bir para politikasıdır. Özellikle 2008 küresel finansal krizine kadar kendisine geniş bir uygulama alanı bulmuş olan enflasyon hedeflemesi politikası kriz ile birlikte özellikle gelişmekte olan ülkelerde bazı sorunların ortaya çıkmasına yol açmıştır. Sorunların çözümünde enflasyon hedeflemesi politikasının etkisiz kalması üzerine daha önceden de literatürde kendisine yer bulmuş olan GDP (Gross Domestic Product) hedeflemesi politikasının uygulanabilirliği tartışılmaya başlanmıştır. Bu çalışmanın amacı; Türkiye’de uygulanan enflasyon hedeflemesi politikasının başarılı olup olmadığını tespit ederek GDP hedeflemesi politikası hakkında bilgi vermektir.
More on Mohr: his final Asheville, North Carolina days
Authors: Davenport L.J. , Wurdack Kenneth J.
Published: July 2021

German-born Charles Mohr (1824–1901) spent most of his adult life working as a pharmacist in Mobile, Alabama. In addition, he contributed multiple scientific and popular articles on the botany of the Southeastern United States. Suffering from many physical ailments, he sought treatment in thermal baths and cool climates, including Asheville, North Carolina. There he was able to work with botanists at the newly established Biltmore Herbarium. In early 1900, he and his family moved to Asheville, where he completed reading the proof of his magnum opus, Plant Life of Alabama. He died in Asheville 17 July 1901—two weeks before his book was published—and is buried there.

Lophophora williamsii (Cactaceae) is thought to be threatened by habitat loss and overharvesting. However, basic demographic and habitat information to evaluate its conservation status have been lacking. We surveyed six wild populations of this species, three in South Texas and three in West Texas, to begin to address this gap. We found high levels of heterogeneity in plant presence and density at multiple spatial scales. While plant densities were not consistently different between South and West Texas, plants were significantly larger in West Texas. The two regions differ strongly in precipitation, temperature, elevation, and topography, all of which are correlated at the regional scale. Therefore, it was not possible to identify which of these variables, or other factors such as competition and human harvesting, may be responsible for the regional differences in plant size. However, our results provide initial information for determining the conservation status of this species.
A floristic inventory and reassessment of the Flora of Sanibel Island (Lee Co.), Florida, U.S.A.
Authors: Wilder George J. , McCollom Jean M. , Thomas Brenda , Relish Karen
Published: July 2021

Sanibel Island (Lee Co., Florida) manifests eight main categories and 12 subcategories of habitats, and individual plant taxa occupy habitat(s) from one or more of those categories. Documented, presently as growing wild/apparently wild on Sanibel Island are individuals of 119 families, 397 genera, 611 species (including two hybrids), and 621 infrageneric taxa of vascular plants. Of the 621 infrageneric taxa, 420 (67.6%) are native and 13 (2.1 %) are endemic to Florida. We interpret the Island’s flora in terms of its history of severe natural and artificial disturbances.
A forty-seven year comparison of the vascular flora at three abandoned rice fields, Georgetown, South Carolina, U.S.A.

Published: July 2021

The vascular flora identified in 1968–1969 in three rice fields of the Winyah Bay Estuary at the Bell W. Baruch Institute for Marine Biology and Coastal Research, Georgetown County, South Carolina, abandoned in 1915, was compared with the vascular flora present in 1987–1991 and 2013–2015. Twenty vascular plant species were identified in 1968–1969 and 22 in 2013–2015 at the most saline marsh, Thousand Acre Rice Field. Forty-seven taxa were reported at Airport Marsh in 1968–1969 and 27 in 2013–2015. Fifty-six taxa were reported at Alderly in 1968–1969 with 41 identified there in 2013–2015. A parsimony algorithm was used to evaluate the distribution and co-occurrence of vascular brackish marsh species in these fields sampled at the three intervals. There was a reduction in flora at the two least saline sites, Alderly and Airport Marsh, from 1968–69 to 1987–91 and 2013–2015. Three factors—rising sea level, an increase in water salinity, and invasion by Phragmites australis—may explain this shift. There was also a shift in the flora at Thousand Acre Rice Field from 1967–1969 to 1987–1991 and 2013–2015 after the marsh was savaged by Hurricane Hugo in 1989. Invasion by non-native Phragmites australis at all sites and increase in water salinity at all sites best explain the reduction in vascular plant species at Airport Marsh and Alderly over the 47-year collection period.
Flow Cytometry ICS Nuclear Antigens v2

Published: July 2021

High-parameter flow cytometry enables identification and characterization of a wide range of cell populations within a biological sample. A combined analysis of extracellular epitope staining (ECS) and intra-cellular epitope staining (ICS) using a collection of fluorophore-labeled antibodies sufficiently identifies discrete cell populations and their respective phenotypes. Importantly, ECS/ICS can be applied to cryo-preserved cell suspensions recovered in tissue culture media, enabling samples to be conveniently analyzed after collection and proper cryopreservation. However, consistent cryopreserved sample recovery and ECS procedures are critical to data comparison across multiple experiments. Herein, we describe a standardized protocol for cryopreserved sample recovery and ECS/ICS procedures for cell-surface and intra-cellular epitope labeling.
Issue Spatiality: A Conceptual Framework for the Role of Space in Public Discourses
Authors: Stoltenberg Daniela
Published: July 2021

Public spheres research has traditionally sidestepped questions of space by focusing on a priori delineated political territories, most prominently national public spheres. While this approach has always lacked nuance, it has become acutely insufficient nowadays, as digital communication technologies easily enable a host of heterogeneous actors to draw public attention to spaces and places at any scale, and communicatively connect places anywhere in the world. This conceptual article argues that communication scholars need to reconsider the spaces embedded in the content of public discourses. Drawing on the notion of issue publics, it understands the public definition of issues as inextricably linked to the places that are communicatively associated with them, causing issue spaces to emerge. The issue space is constructed through place-naming whenever public actors reference places in the context of issues. The article develops issue spatiality as an analytical framework to understand the role of place and space in public discourse. It discusses how issue spatiality enables a better understanding of the increasingly complex scales of public communication, and outlines several dimensions of issue spatiality. Drawing on communication infrastructure literature, it proposes socio-spatial inequalities of communicative resources as important predictors of issue spatiality, along with the habits of professional communicators, and local problem properties. Gazetteers and mapping techniques are introduced as methodological interventions required for the empirical use of issue spatiality.
Spaces, Places, and Geographies of Public Spheres: Exploring Dimensions of the Spatial Turn
Authors: Waldherr Annie , Klinger Ulrike , Pfetsch Barbara
Published: July 2021

For decades, scholars have been calling out a spatial turn in media and communication studies. Yet, in public sphere research, spatial concepts such as space and place have mainly been used metaphorically. In recent years, the abundance of digital trace data offers new opportunities to locate communicative interactions, sparking new interest in the spatial turn in media and communication and opening up new perspectives on spaces and places also within public sphere research. Digital location data enables one to: study the places and spaces in which (semi-)public communication is embedded; uncover geographical inequalities between countries, regions, cities, and peripheries; and highlight the local contexts of public spheres. This thematic issue gathers some of these endeavors in one place, bringing together conceptual, methodological, and empirical contributions that spell out the spatiality of public spheres in detail and combine the analysis of spaces, places, and geographies with long-standing concepts of public sphere research.

Published: July 2021

BACKGROUND: Despite their targeted effects, targeted drug therapies also lead to adverse events, including various cardiac effects. AIM: This study aims to determine the possibility of treating cardiovascular diseases underlying or occurring as a side effect of ibrutinib treatment without blocking targeted therapy for chronic lymphocytic leukemia (CLL). MATERIALS AND METHODS: From 2016 to the present, we have examined and followed 217 patients with CLL who were continuously treated with ibrutinib targeted therapy for five years. The study included patients with CLL, aged 32 to 91 years [median age of 66.0 (32.091.0) years], including 136 men aged 66.0 (32.091.0) years and 81 women aged 65.0 (39.083.0) years. All patients underwent electrocardiography, echocardiography, 24-hour electrocardiographic Holter monitoring, 24-hour blood pressure monitoring, assessment of comorbidities using the Charlson Index, and screening for fragility using the G8 questionnaire. RESULTS: Active cardiac monitoring, including continuous remote monitoring of cardioprotective therapy intake and efficiency, allows oncohematological patients to achieve higher overall survival rates. The long-term monitoring group included a statistically significant number of patients with atrial fibrillation and/or arterial hypertension and patients who receive dual and triple antithrombotic therapy. This group included patients with CLL and more severe cardiac status than other patients, who were regularly observed by a cardiologist. CONCLUSIONS: Widespread introduction of the techniques for continuous remote monitoring of the oncological patients condition into clinical practice will improve the patients quality of life and increase their life expectancy.
