Published: February 2022

Background

Hospice care is a multidisciplinary approach that focused on patients’ quality of life, and nurses allocate more of their time with patients and patients’ families than those nurses working in other disciplines. Nurses’ knowledge of and attitudes toward hospice care can affect the quality of hospice care. At present, China’s hospice care institutions are suffering from an obvious shortage of nursing staff. Since clinical nurses are the main force behind the future provision of hospice care, their knowledge of, attitudes and willingness to practice can greatly promoted the growth of hospice care, however, available data on clinical nurses’ willingness to practice hospice care are limited.

Methods

A cross-sectional descriptive study design was employed to collect data from 1833 nurses working in tertiary or secondary general hospitals in Guangxi, China. We examined nurses’ demographic characteristics and scores on the Chinese version of the hospice care knowledge scale, the Chinese version of the Bradley Attitude Assessment Questionnaire, and a brief quiz concerning their willingness to practice hospice care in the future. Descriptive, single factor, multiple regression analyses and logistic regression analyses were used for data analysis.

Results

Nurses displayed moderate mean scores for both knowledge of and attitudes, and only 505 (27.5%) nurses expressed their willingness to practice hospice care, 1329 (72.5%) of nurses sampled expressed their unwillingness or uncertainty. Multivariate regression analyses showed that education, professional qualification, monthly income, whether they had been trained in hospice care, and willingness to practice hospice care were the main influencing factors of knowledge; education, whether they lived with someone aged >60 years, and whether they had been trained in hospice care were main factors influencing attitudes. Additionally, logistic regression analyses showed that hospice care knowledge, whether they had been trained in hospice care, and whether they had clinical experience affected the nurses’ willingness to practice hospice care.

Conclusion

This study highlighted a knowledge gap and moderate attitudes toward hospice care among nurses, and most nurses did not prefer to practice hospice care. Having been trained in hospice care was the main common factor of nurses’ knowledge of, attitudes toward, and willingness to practice hospice care in the future, indicating the necessity to provide nurses with more targeted hospice care training.
Resting-state electroencephalography based deep-learning for the detection of Parkinson’s disease
Authors: Shaban Mohamed , Amara Amy W.
Published: February 2022

Parkinson’s disease (PD) is one of the most serious and challenging neurodegenerative disorders to diagnose. Clinical diagnosis on observing motor symptoms is the gold standard, yet by this point nerve cells are degenerated resulting in a lower efficacy of therapeutic treatments. In this study, we introduce a deep-learning approach based on a recently-proposed 20-Layer Convolutional Neural Network (CNN) applied on the visual realization of the Wavelet domain of a resting-state EEG. The proposed approach was able to efficiently and accurately detect PD as well as distinguish subjects with PD on medications from subjects who are off medication. The gradient-weighted class activation mapping (Grad-CAM) was used to visualize the features based on which the approach provided the predictions. A significantly high accuracy, sensitivity, specificity, AUC, and Weighted Kappa Score up to 99.9% were achieved and the visualization of the regions in the Wavelet images that contributed to the deep-learning approach decisions was provided. The proposed framework can then serve as an effective computer-aided diagnostic tool that will support physicians and scientists in further understanding the nature of PD and providing an objective and confident opinion regarding the clinical diagnosis of the disease.
Ranking the biases: The choice of OTUs vs. ASVs in 16S rRNA amplicon data analysis has stronger effects on diversity measures than rarefaction and OTU identity threshold

Published: February 2022

Advances in the analysis of amplicon sequence datasets have introduced a methodological shift in how research teams investigate microbial biodiversity, away from sequence identity-based clustering (producing Operational Taxonomic Units, OTUs) to denoising methods (producing amplicon sequence variants, ASVs). While denoising methods have several inherent properties that make them desirable compared to clustering-based methods, questions remain as to the influence that these pipelines have on the ecological patterns being assessed, especially when compared to other methodological choices made when processing data (e.g. rarefaction) and computing diversity indices. We compared the respective influences of two widely used methods, namely DADA2 (a denoising method) vs. Mothur (a clustering method) on 16S rRNA gene amplicon datasets (hypervariable region v4), and compared such effects to the rarefaction of the community table and OTU identity threshold (97% vs. 99%) on the ecological signals detected. We used a dataset comprising freshwater invertebrate (three Unionidae species) gut and environmental (sediment, seston) communities sampled in six rivers in the southeastern USA. We ranked the respective effects of each methodological choice on alpha and beta diversity, and taxonomic composition. The choice of the pipeline significantly influenced alpha and beta diversities and changed the ecological signal detected, especially on presence/absence indices such as the richness index and unweighted Unifrac. Interestingly, the discrepancy between OTU and ASV-based diversity metrics could be attenuated by the use of rarefaction. The identification of major classes and genera also revealed significant discrepancies across pipelines. Compared to the pipeline’s effect, OTU threshold and rarefaction had a minimal impact on all measurements.
Transforming education with Black diaspora film and filmmaking practice
Authors: Ellis Ashley D.
Published: February 2022

At the first Third World Filmmakers Meeting held in Algiers in 1973, participants resolved that the cinema they envisioned could conscientize audiences and continue Indigenous and African storytelling traditions. Today, there is a robust canon of Black diaspora cinema, which should be preserved, archived and analysed. Yet when coupled with filmmaking practice, it can become living history as a tool in the application of critical pedagogy. This article considers Black diaspora film and filmmaking practice as mechanisms for the radical transformation of education. It examines how oppositional cinematic representations can spark critical consciousness and how filmmaking practice can put emotional intelligence at the centre of learning.
Theatrical cinema in South Africa: The Parasite within, South Korea as a model for survival
Authors: Brown David Max
Published: February 2022

The 2019 Oscar winner, Parasite attracted millions to South Korean cinemas even before its success in Hollywood. Nigerian cinema is also growing, with local movies topping the theatrical box office and new cinemas being built. Meanwhile, in South Africa, feature film production and cinema attendance are declining without significant transformation of access to the means of film production or to distribution and exhibition. Practical propositions, including the implementation of quotas and taxes, are presented as remedies for the survival of South African cinema, particularly in relation to content creation and the expansion of the exhibition infrastructure.

Las funciones institucionales de las mujeres de la familia de Augusto: Octavia, Livia y Julia
Authors: López Gómez Helena
Published: February 2022

El presente artículo pretende ofrecer una visión sobre el papel institucional desarrollado por las principales mujeres de la familia de Augusto. De esta forma nos proponemos entender la forma en que el “cargo” de emperatriz romana se comienza a perfilar a inicios del Imperio. Para ello se tiene en cuenta la labor precursora de muchas mujeres tanto de la legendaria monarquía como de la República que, con sus acciones audaces captaron la atención de los historiadores antiguos y comenzaron la senda de empoderamiento femenino, reconociéndose su relevancia en ciertos aspectos de la vida pública y política. Estas mujeres ocupan los relatos de los autores en momentos puntuales, como Tanaquil o Lucrecia en época monárquica o Cornelia, Hortensia o Fulvia en la República. Sin embargo, las mujeres de las familias imperiales y, concretamente, las de la domus Augusta, son las primeras en desarrollar un rol público constante y sistemático. Junto a la mayor parte de emperadores se encuentran mujeres poderosas que los acompañan. Así pues, en las primeras décadas del principado se da la entrada de la mujer en el ámbito del poder de una forma más abierta, reconociéndose su propia relevancia. En este sentido, en el artículo se analiza cómo, pese a la naturaleza conservadora del nuevo régimen de Augusto, se permitió este avance en la posición pública femenina sin que ello supusiese una inversión en los roles de género o un revuelo para la sociedad del momento. A través de las figuras de Octavia, Livia y Julia se estudiará la forma en que se comenzó a perfilar la posición de la mujer en el poder a través de su labor institucional como parte de la familia imperial. Así pues, estas mujeres empezarán a tener un papel propio en un terreno antes vedado. La transición culminará con las condiciones especificadas en el testamento del princeps en relación a la situación que su viuda debía mantener tras su muerte. Con ello, se consolidarán las bases del rol de emperatriz y Augusta para las restantes generaciones del Alto Imperio.
PLATFORM EMPLOYMENT IS THE MAIN TREND OF LABOR MARKET DEVELOPMENT IN MODERN CONDITIONS
Authors: Glotova N. I. , Gerauf Yu. V.
Published: February 2022

The relevance of the study lies in the fact that today the infrastructural development of the labor market is associated primarily with digital platforms, which are the main tool for balancing supply and demand in terms of employer and jobseeker activity. The emergence of digital platforms has changed the organization and structure of the labor market. The coronavirus pandemic has further contributed to the development of employment on service-oriented and web-based platforms. Russian business, in order to reduce its costs, began to willingly use the services of freelancers. However, the regime of the self-employed, today, does not imply social guarantees, the consolidation of which in Russian legislation will contribute not only to an increase in the number of «legal» selfemployed, but also to the country’s economy as a whole.

The article reveals the role of platform employment as the main tool for compensating for structural problems or shifts when capable, but not employed people appear in society. The main advantages and disadvantages of digital platforms for workers, employers and the economy as a whole are characterized. The aim of this work is to study platform employment as the main trend in the development of the labor market in Russia, to identify the advantages and risks of platform employment, as well as tools for its regulation.
TRANSFORMATION OF THE FORMAT OF LABOR PROTECTION REQUIREMENTS IN CONNECTION WITH CONSUMER HABITS OF INFORMATION PERCEPTION
Authors: Senchenko V. A. , Kaverzneva T. T. , Kitaev S. V. , Abdrakhmanov N. Kh.
Published: February 2022

Instructions on labor protection in today’s form have existed since the last century. During this time, mobile phones and the Internet appeared, people landed on the moon. The occupational safety instructions remained unchanged.

Generation Z is increasingly beginning to enter the workforce. It’s representatives are distinguished from the previous generation by the fact that they were actually “born with tablets, mobile phones and smartphones.” From birth, they are surrounded by a “digital web”, since Internet technologies are an integral part of their parents’ lives. This is the first generation deeply involved in digital technologies, so the archaic format of reporting labor protection requirements in form and content for new generations becomes ineffective.

This article provides a historical digression of the legislative framework regulating the legal status of labor protection instructions. The calculation of the economic officiency of paper and digital virsions of their placement has been carried out. The transition to the digital format of labor protection instructions based on changes in consumer habits of information perception is justified. For the convenience of using the instructions, it is proposed to use a QR-code with a link to the location of the place of their placement.
Binary Data Matrix Theory
Authors: Amiri Manouchehr
Published: February 2022

In this paper after introducing a model of binary data matrix (BDM) for physical parameters of an evolving system (of particles), we develop a Hilbert space as an ambient space to derive induced metric tensor on embedded parametric manifold identified by associated joint probabilities of particles observables (parameters). Parameter manifold assumed as space-like hypersurface evolving along time axis, an approach that resembles 3+1 formalism of ADM and numerical relativity. We show the relation of endowed metric with related density matrix. Identification of system density matrix by this metric tensor, leads to the equivalence of quantum Liouville equation and metric compatibility condition

=0 while covariant derivative of metric tensor has been calculated respect to Wick rotated time or spatial coordinates. After deriving a formula for expected energy per particles, we prove the equality of this expected energy with local scalar curvature of related manifold. We show the compatibility of BDM model with Hamilton-Jacobi formalism and canonical forms. On the basis of the model, I derive the Ricci flow like dynamics as the governing dynamics and subsequently derive the action of BDM model and Einstein field equations. Given examples clarify the compatibility of the results with well-known principles such as equipartition energy principle and Landauer’s principle. This model provides a background for geometrization of quantum mechanics compatible with curved manifolds and information geometry. Finally, we conclude a “bit density principle” which predicts the Planck equation, De Broglie wave particle relation,

A Review of the Development and Applicability of Double-Skin Facades in Hot Climates
Authors: Abtar Aare N.
Published: February 2022

A double-skin façade (DSF) is a multilayered skin that was initially designed for the cold climate of European countries with noticeable success. Since then, countries in different climates started looking into the possibility of adopting DSF through the use of computer simulations to avoid any unforeseen problems in real life. This study aims to look into the possibility and level of success in using DSF in the Middle East’s hot-arid climate, making it a challenge compared to European countries. The study utilized a quantitative investigative approach in analyzing the results of some studies done in different countries in the Middle East. After looking into the results from different papers, careful considerations have to be made for the building due to its location and microclimate todetermine specific parameters (e.g., combination of transparent and opaque materials, proportion between floor level and screen height, orientation and cavity depth), these would lead to a significant impact on reducing a building’s cooling loads and energy efficiency. It is worth noting that mechanical ventilation (e.g., supplying all return cool air from internal spaces into the DSF cavity or integrating the building’s heating, ventilation, and air-conditioning system with the façade) is necessary for DSF in hot climates to cool and maintain its cavity’s temperature to function properly. However, this increases cooling loads, energy consumption, and running costs of the building which architects have to consider to determine the most efficient and economical solution in material and equipment.

Penulisan ini bertujuan untuk mengetahui status dan karakteristik dari perspektif hukum terhadap ruang udara diatas Alur Laut Kepulauan Indonesia (ALKI) dalam relasinya dengan kedaulatan yang bisa dilaksanakan oleh negara kepulauan. Berdasarkan kajian normatif didapatkan hasil bahwa pada ruang udara di atas ALKI dibawah rezim hukum khusus (sui generis) sebagai inovasi yang lahir pasca UNCLOS 1982, menjadikan pelaksanaan kedaulatan negara di wilayah udara dibatasi. Selanjutnya, pelaksanaan kedaulatan oleh negara tidak dapat menerapkan hard law yang dapat berpotensi menghambat dan menangguhkan pelaksanaan hak lintas penerbangan alur laut kepulauan oleh pesawat udara asing, hal ini juga telah terlihat secara historis dalam perumusan konsep awal negara kepulauan dalam UNCLOS 1982.

Lintah laut (Zeylanicobdella arugamensis) merupakan salah satu ektoparasit yang mudah dilihat dan dilakukan perbanyakan untuk penelitian. Tujuan dari percobaan ini adalah untuk mengetahui teknik perbanyakan dan isolasi lintah laut (Z. arugamensis), serta pemindahan ikan kerapu terinfeksi lintah laut. Percobaan ini dilakukan untuk memfasilitasi kegiatan penelitian lintah laut secara in vitro maupun in vivo. Perbanyakan lintah laut dilakukan dengan metode kohabitasi. Masing-masing dua dan tiga ekor ikan kerapu hibrida cantang sakit (TL: 30-35 cm) dikohabitasi dengan 25 ekor ikan kerapu hibrida cantang sehat (TL: 7,5-9,2 cm) selama satu bulan. Isolasi lintah laut dari ikan sakit maupun dinding bak dilakukan dengan teknik pengambilan dengan tangan dan teknik perendaman dengan air tawar. Pemindahan ikan sakit dari bak kohabitasi ke bak uji in vivo dilakukan dengan teknik menggunakan seser dan teknik menggunakan keranjang kecil. Hasil percobaan menunjukkan teknik kohabitasi menghasilkan perkembangbiakan lintah laut yang cepat. Isolasi lintah laut dengan tangan memberikan variasi ukuran lintah dalam cawan petri, sedangkan isolasi lintah laut dengan perendaman menimbulkan kematian lintah laut dan memerlukan waktu pemulihan kondisi lintah lebih lama. Isolasi lintah laut dari dinding bak memperoleh lebih banyak lintah dewasa, namun telur yang dihasilkan lebih sedikit dibandingkan kedua perlakuan sebelumnya. Pemindahan ikan terinfeksi lintah laut dengan teknik menggunakan dua keranjang kecil lebih sedikit melepaskan dan menghilangan lintah dari tubuh ikan dibandingkan dengan teknik menggunakan seser atau serok.

Ikan tapah Wallago leerii merupakan ikan karnivor yang hidup di perairan sungai besar di Sumatera dan Kalimantan. Kegiatan ini dilakukan bertujuan untuk mengamati pola pertumbuhan, sintasan, dan kondisi parameter darah ikan tapah yang dipelihara pada kolam semi-beton pada tahap domestikasi. Ikan tapah diperoleh dari Sungai Kampar, Riau dan dipelihara di kolam semi-beton (60 m2) di Instalasi Riset Plasma Nutfah Perikanan Air Tawar Cijeruk, Bogor. Ikan tapah diberi pakan hidup berupa benih ikan nila dan ikan nilem sebanyak 5% bobot tubuh. Sampling dilakukan sebulan sekali untuk mengetahui pertumbuhan, sintasan, dan parameter darah ikan. Hasil menunjukkan bahwa ikan tapah betina memiliki rata-rata panjang dan bobot yang lebih besar dibandingkan ikan jantan. Pola pertumbuhan ikan tapah baik jantan dan betina mengalami pertumbuhan yang stagnan, namun ikan tapah yang dipelihara memiliki sintasan 100%. Belum optimalnya pertumbuhan ikan tapah dapat disebabkan karena perbedaan kondisi lingkungan dengan habitat aslinya sehingga ikan tapah masih berusaha beradaptasi dan mengalami stres yang mengakibatkan berkurangnya nafsu makan. Kondisi meningkatnya stres ikan tapah dapat dilihat dari parameter darah terutama hemoglobin dan kortisol. Secara umum kadar glukosa darah dan hemoglobin pada induk ikan tapah cenderung mengalami penurunan saat akhir masa pemeliharaan dibandingkan dengan awal pemeliharaan. Sedangkan pada parameter kortisol, nilainya cenderung mengalami peningkatan saat awal sampai akhir percobaan.

Authors: Ilham Ilham , Safar Safar , Hamzah Hamzah
Published: February 2022

Caulerpa lentillifera termasuk dalam golongan alga hijau. Produksi C. lentillifera masih rendah karena mengandalkan hasil dari alam sehingga dibutuhkan teknologi budidaya untuk menunjang kontinuitas produksi C. lentillifera. Perbedaan biomassa awal pada saat penanaman sangat berpengaruh terhadap pertumbuhan rumput laut. Hal ini sangat berkaitan dengan persaingan setiap individu rumput laut dalam mendapatkan unsur hara sebagai makanannya. Keberhasilan sistem penanaman dipengaruhi oleh penggunaan bibit yang baik dan bobot yang sesuai akan meningkatkan pertumbuhan. Kegiatan ini bertujuan untuk mengetahui pengaruh perbedaan bobot awal penanaman terhadap pertumbuhan C. lentillifera. Kegiatan ini dilaksanakan pada bulan Juli-Oktober 2020 di tambak penampungan air limbah udang Kabupaten Takalar, Sulawesi-Selatan. Tanaman uji yang digunakan dalam kegiatan ini adalah rumput laut dari jenis C. lentillifera yang berasal dari Tambak Laikan Kabupaten Takalar, Sulawesi Selatan.

A Study of the Characteristics of the 137Cs of the South China Sea in Batam Waters has been carried out. The South China Sea through several straits is connected to the Pacific Ocean region and the Indonesian Sea. The mass of Pacific water entering the South China Sea will reach Batam Waters with radioactive contaminants. Batam Waters are part of the Karimata Strait which is the Extention Line of South China Sea so that it has the potential to receive 137Cs of radioactive contaminants from operational nuclear reactors discharged in the coastal regions of China. The purpose of the study is to find out the characteristics of 137Cs and obtain the current status of 137Cs as a baseline to minimize the impact of nuclear activities on the ecosystem of the waters of Batam, Indonesia. The 137Cs characterization method uses the Ammonium Phosphomolibdate (AMP) with modification of base dissolution and measurement validation with Certified Reference Material (CRM). The results of monitoring the concentration of 137Cs in seawater in Batam waters are in the range <0.03 - 0.35 ± 0.02 Bq.m-3, while the concentration of 137Cs activity in Batam waters sediments is known to be a maximum of 0.22 ± 0.08 Bq.kg-1 with 134Cs below MDA.

Religion as a Self-Referential System of Religious Communication: An Assessment with Questions for a Challenging New Theological System. Notes of a Preliminary and (Merely) Intuitive Approach
Authors: Abreu Fábio Henrique
Published: February 2022

ABSTRACTThe following considerations do not properly configure an academic article, but rather intend to offer a critical reaction to the lecture given by Prof. Dr. habil. Christian Danz, from the University of Vienna, on the occasion of the “25th Seminar in Dialogue with the Thought of Paul Tillich” – held under the title “Religion, Language, and Culture: Relevance and Limits of Paul Tillich’s Theology of Culture for the 21st Century,” between September 15th and 22nd, 2021. Danz’s lecture, entitled “Theology, Religion, Culture. Reflections on the Task of Systematic Theology following Paul Tillich,” brings not only an exegetical exposition of Tillich’s theology of culture, but also a sturdy criticism regarding the foundation of his concept of religion in the face of the religious pluralism of modern democratic societies. The thesis presented by Danz can be summarized in three points: 1) the transcendental foundation of Tillich’s concept of religion makes his theology incapable of dealing with religious pluralism; 2) given that the academic concept of religion is a product of neo-Protestantism, the concept of religion must be restricted to the Christian religion; 3) finally, the function of the concept of religion within the theological system lies in its ability to conceptually apprehend and determine Christianity as a religion. Based on the critique of the foundation of the concept of religion developed by Tillich, Danz proposes a new concept of religion in the perspective of a “self-referential system of religious communication.” Constitutive to the self-referential system of religious communication is the concept of “verstehende Aneignung,” or “understanding appropriation,” which, in turn, can only occur within the system of religious communication. The text that follows is an attempt, and while still incipient and intuitive, it offers a rather “suspicious” approach to the theological system proposed by Danz. The first part is intended for a comprehensive synthesis of the substantive content of the lecture given. The second part presents initial considerations and questions regarding the foundations of the proposed new theological system.
Distopia e religião em perspectiva tillichiana
Authors: Santos J Marçal G
Published: February 2022

A distopia consolidou-se como gênero narrativo no decorrer do século XX tanto na literatura quanto no cinema a partir de uma pretensão crítica à modernidade. Em contraste com a tradição literária iniciada pelo humanista inglês Tomas Morus, em Utopia (1516), a narrativa distópica desloca a ideia de não-lugar implicado no neologismo utopia da referência espacial e a situa em um tempo futuro, no qual o potencial destrutivo do presente é efetivado dramaticamente. O que nos interessa é a recorrência do tema religioso nesse conjunto de obras, para o que nos propomos delinear categorias analíticas em diálogo com a teologia da cultura.
Ontologia da angústia e coragem em Paul Tillich
Authors: Nilo da Silva Henrique Nilo
Published: February 2022

Nossa proposta para o GT6 Paul Tillich, constitui-se em uma breve análise teórica-bibliográfica da ontologia da angústia e coragem que Paul Tillich desenvolveu em sua obra A Coragem de Ser (1952). Em diálogo interdisciplinar com a tiefenpsychologie e psicanálise  investiga a situação existencial humana. Para apresentarmos a ontologia tillichiana utilizaremos três de suas preleções nas conferências pronunciadas na Yale University, organizadas no texto de 1952: Ser e Coragem; Ser, Não-Ser e Angústia; e Angústia Patológica, Vitalidade e Coragem. Em cada sessão apresentaremos o pensamento do autor em diálogo com textos de pesquisadores e estudiosos da religião. Primeiramente, mostraremos o percurso filosófico que o autor faz para chegar em seu conceito de coragem como “auto-afirmação” apesar da finitude, alienação e neuroses. Depois, apresentaremos o esforço da ontologia tillichiana de compreender as principais questões existenciais do homem moderno e contemporâneo. Por fim, analisar o estado de confusão da teoria psicoterapêutica da angústia que não diferencia a angústia existencial da patológica. Destarte, ressaltando que a análise ontológica é um material para  a psicologia formular uma teoria consistente e prática eficiente. Consequentemente, destacamos a contribuição da ontologia da angústia e coragem tillichiana para a psicologia e os estudos de religião.
The challenges of implementing the Curriculum and Assessment Policy Statement in accounting

Published: February 2022

South African schools have experienced several curriculum changes over the past few years. In this article we report on the findings regarding the challenges experienced by heads of department (HODs) with the implementation of the Curriculum and Assessment Policy Statement (CAPS) in accounting. A qualitative approach, modelled on the interpretative perspective, was used to explore these challenges, namely: medium of instruction; time allocated to complete the syllabus; poor subject content foundation; progression of learners; and the integration of economic and management sciences (EMS). Open-ended individual interviews with 12 HODs were used as a data-collection technique. The findings indicate that the time allocated in the annual teaching plan (ATP) for accounting may have a negative impact on effective teaching and learning and learner performance. It has also been noted that EMS teachers are not sufficiently competent to teach financial literacy, which may affect learners’ subject choices prior to Grade 10. Grade 8 and 9 learners lack exposure to accounting due to subject integration and learner progression. Furthermore, accounting textbooks do not prepare learners for school-based assessments (SBAs) or examinations. Recommendations include that subject choice should occur in Grade 8, rather than Grade 10, and that a secondary school improvement programme (SSIP) should start from Grade 10, and not Grade 12.

Authors: Markova M. A.
Published: February 2022

The article is devoted to the analysis of the marriage behaviour of Catholics in Tsarskoye Selo and Yamburg parishes of the Saint Petersburg governorate. For this purpose, the Russian-language copies of 1840–1859 parish registers, deposited in the 1822 collection (Petrograd Dean’s Office of Roman Catholic Churches) of the Central State Historical Archives of St. Petersburg were analysed. Statistical methods of processing mass sources were applied, the data were processed using Excel spreadsheets. The article examines the seasonal distribution of marriages, the average age at first marriage, peculiarities of the marriage choice of Catholics. The research findings were compared with the indicators previously obtained for the Orthodox population of Tsarskoye Selo in the 1840s.
Worry about COVID-19 and its effects on the online political participation of citizens in the Ecuadorian context
Authors: Zumárraga-Espinosa Marcos , Egas-Balseca Sonia , Reyes-Valenzuela Carlos

During the COVID-19 pandemic, confinement and mobility restrictions gave rise to different questions regarding the use and perceptions on public space, where the relational and contextual properties of this space may cause a diversity of emotions. We use machine learning and social network analysis to explore emotions in relation to the public space, based on attributes extracted from photos of the city of Quito, Ecuador, taken between April and June 2020. Our results show that an attribute of the urban landscape can be associated with positive and negative emotions, and that opposite attributes of the images (i.e., glossy and dirty) can both influence positive emotions regarding public space. This research inaugurates a new field of study in Latin America regarding urban emotions, and also supports a better understanding of citizen perceptions of the public space during the pandemic crisis.
Political Influencers on YouTube: Business Strategies and Content Characteristics
Authors: Fischer Tasja-Selina , Kolo Castulus , Mothes Cornelia
Published: February 2022

Young media users increasingly engage with public affairs via social media such as YouTube, where content is increasingly produced by influencers who neither represent established professional news media nor political parties. Although the audience of these channels is already substantial in absolute terms and still growing enormously—making alternative influencers serious competitors to professional journalism—we still know little about their ways of attracting and monetizing audiences, the topics they emphasize, or the specific content they provide. To address this void, the present study examines political videos and their producers on YouTube in an explorative and comparative way for English- and German-speaking YouTube channels. We conducted a content analysis of the five most popular YouTube videos for each of the 20 most successful English- and German-speaking political influencers in 2020. Our analyses show that, although English YouTubers already appear to be more professionalized, similar patterns emerge in both language regions, particularly with regards to increasing efforts to manage microcelebrity status. In terms of content, two main types of political YouTube videos were identified: “partisan mockery” and “engaging education.” Results will be discussed in terms of their implications for political discourse, youth participation, and established journalistic media.

Published: February 2022

Background: The practice of self-medication is expected to be higher in health science students due to their exposure to knowledge about different diseases and drugs. This study was done to assess the knowledge, attitude and practice of self-medication and to compare the impact of knowledge of Pharmacology on it, among second-year MBBS students.Methods: A semi-structured questionnaire consisting of both open-ended and close-ended questions was prepared and given to second-year medical students of Kurnool medical college, Kurnool. Data was analysed and entered in Microsoft Excel (version 2019), and associations were tested using the Chi-square test. The results are expressed as counts and percentages. Statistical significance was p<0.05.Results: Among the respondents, 37.33% are practising self- medication, 54.66% think knowledge of Pharmacology aids students to practice without any dire consequences. Most of the students take for fever (95.33%), (97.33%) for cough, cold, sore throat.84% were aware that it’s not safe to take drugs pertaining to alternate systems of medicine like Ayurveda, homoeopathy. A statistically significant association between knowledge, attitude, practice and gender and residence has been observed.Conclusions: The study shows that students are aware that self-medication is dangerous when followed by lay people. On the other hand, health professionals with knowledge about medications can take self-medication for common conditions without any dire consequences. They are also aware that it’s not safe to take medications that come under alternate systems of medicines, and WhatsApp consultation is not to be encouraged.
