Effect on health-related quality of life of the X-Bolt dynamic plating system versus the sliding hip screw for the fixation of trochanteric fractures of the hip in adults: the WHiTE Four randomized clinical trial
Authors: Griffin Xavier L. , Achten Juul , O'Connor Heather Marie , Cook Jonathan A. , Costa Matt L. ,   on behalf of the WHiTE Four Investigators
Published: January 2021

Aims

Surgical treatment of hip fracture is challenging; the bone is porotic and fixation failure can be catastrophic. Novel implants are available which may yield superior clinical outcomes. This study compared the clinical effectiveness of the novel X-Bolt Hip System (XHS) with the sliding hip screw (SHS) for the treatment of fragility hip fractures.

Methods

We conducted a multicentre, superiority, randomized controlled trial. Patients aged 60 years and older with a trochanteric hip fracture were recruited in ten acute UK NHS hospitals. Participants were randomly allocated to fixation of their fracture with XHS or SHS. A total of 1,128 participants were randomized with 564 participants allocated to each group. Participants and outcome assessors were blind to treatment allocation. The primary outcome was the EuroQol five-dimension five-level health status (EQ-5D-5L) utility at four months. The minimum clinically important difference in utility was pre-specified at 0.075. Secondary outcomes were EQ-5D-5L utility at 12 months, mortality, residential status, mobility, revision surgery, and radiological measures.

Results

Overall, 437 and 443 participants were analyzed in the primary intention-to-treat analysis in XHS and SHS treatment groups respectively. There was a mean difference of 0.029 in adjusted utility index in favour of XHS with no evidence of a difference between treatment groups (95% confidence interval -0.013 to 0.070; p = 0.175). There was no evidence of any differences between treatment groups in any of the secondary outcomes. The pattern and overall risk of adverse events associated with both treatments was similar.

Conclusion

Any difference in four-month health-related quality of life between the XHS and SHS is small and not clinically important. There was no evidence of a difference in the safety profile of the two treatments; both were associated with lower risks of revision surgery than previously reported.

An epidemiological analysis of revision aetiologies in total hip arthroplasty at a single high-volume centre
Authors: Kerzner Benjamin , Kunze Kyle N. , O’Sullivan Michael B. , Pandher Karan , Levine Brett R.
Published: January 2021

Aims

Advances in surgical technique and implant design may influence the incidence and mechanism of failure resulting in revision total hip arthroplasty (rTHA). The purpose of the current study was to characterize aetiologies requiring rTHA, and to determine whether temporal changes existed in these aetiologies over a ten-year period.

Methods

All rTHAs performed at a single institution from 2009 to 2019 were identified. Demographic information and mode of implant failure was obtained for all patients. Data for rTHA were stratified into two time periods to assess for temporal changes: 2009 to 2013, and 2014 to 2019. Operative reports, radiological imaging, and current procedural terminology (CPT) codes were cross-checked to ensure the accurate classification of revision aetiology for each patient.

Results

In all, 2,924 patients with a mean age of 64.6 years (17 to 96) were identified. There were 1,563 (53.5%) female patients, and the majority of patients were Caucasian (n = 2,362, 80.8%). The three most frequent rTHA aetiologies were infection (27.2%), aseptic loosening (25.2%), and wear (15.2%). The frequency of rTHA for adverse local tissue reaction (ALTR) was significantly greater from 2014 to 2019 (4.7% vs 10.0%; p < 0.001), while the frequency of aseptic loosening was significantly greater from 2009 to 2013 (28.6% vs 21.9%; p < 0.001).

Conclusion

Periprosthetic joint infection was the most common cause for rTHA in the current cohort of patients. Complications associated with ALTR necessitating rTHA was more frequent between 2014 to 2019, while aseptic loosening necessitating rTHA was significantly more frequent between 2009 to 2013. Optimizing protocols for prevention and management of infection and ALTR after THA may help to avoid additional financial burden to institutions and healthcare systems.

Competing Hazards Regression Parameter Estimation Under Different Informative Priors
Authors: Rehman H. , Chandra N. , Hosseini-Baharanchi Fatemeh Sadat , Baghestani Ahmad Reza
Published: January 2021

In the analysis of survival data, cause specific quantities of competing risks get considerable attention as compared to latent failure time approach. This article focuses on parametric regression analysis of survival data using cause specific hazard function with Burr type XII distribution as a baseline model. We obtained maximum likelihood and Bayes estimates of cumulative cause specific hazard functions under competing risk setup. For Bayesian point of view we proposed a class of informative priors for parameters to observe the comprehensive compatibility and their effectiveness under two different loss functions. The appropriateness of model is measured by the simulation study. Finally, we illustrate the proposed methodologies using bone marrow transplant data from the Princess Margaret Hospital Ontario, Canada.
An Improvement in Estimation of Population Mean using Two Auxiliary Variables and Two- Phase Sampling Scheme under Non-Response
Authors: Chaudhary Manoj K. , Kumar Amit
Published: January 2021

In the present paper, we have proposed some improved ratio and regression-type estimators of the finite population mean utilizing the information on two auxiliary variables in the presence of non-response. The two-phase sampling scheme has been used to accomplish the job of estimating the desired parameter. The expressions for the basic properties such as bias and mean square error (MSE) of the proposed estimators have been derived up to the first order of approximation. A comparative study of the proposed estimators with some existing estimators has also been carried out through a real data set.
Dispersion cancellation in a quantum interferometer with independent single photons
Authors: Im Dong-Gil , Kim Yosep , Kim Yoon-Ho
Published: January 2021

A key technique to perform proper quantum information processing is to get a high visibility quantum interference between independent single photons. One of the crucial elements that affects the quantum interference is a group velocity dispersion that occurs when single photons pass through a dispersive medium. We theoretically and experimentally demonstrate that an effect of group velocity dispersion on the two-photon interference can be cancelled if two independent single photons experience the same amount of pulse broadening. This dispersion cancellation effect can be applied to a multi-path linear interferometer with multiple independent single photons. As multi-path quantum interferometers are at the heart of quantum communication, photonic quantum computing, and boson sampling applications, our work should find wide applicability in quantum information science.

Tea is one of the most popular beverages in the world. Produced from Camellia sinensis leaves, tea has been studied to provide health benefits due to the content of important metabolites. This study aimed to investigate the catechin contents, antioxidant, and antibacterial activities of Indonesian tea varieties, namely green tea, black tea, and white tea. Tea infusion was prepared by extracting 1 g of each sample into 10 mL of distilled water and incubated at 80 °C for 60 min. The catechin and epigallocatechin gallate (EGCG) contents of tea extracts were determined using high-performance liquid chromatography (HPLC). Antioxidant activity was measured using the free radical method with 2,2-diphenyl-1-pycrylhidrazyl (DPPH), while antimicrobial activity was assesed using paper disc diffusion assay. The results indicated that green tea had the highest contents of catechin (646 ± 17.14 mg/L) and EGCG (997.8 ± 36.72 mg/L), and antioxidant activity with IC50 of  5.65 µg/mL. Furthermore, green tea and white tea extracts showed inhibitory activity against Gram-positive bacteria such as Micrococcus luteus, Bacillus subtilis, and Staphylococcus aureus whereas black tea had no activity against all bacterial strains tested. Generally, we concluded that white tea and green tea contributed to the higher content of catechins and exhibited strong antioxidant and antibacterial properties.
On the Problems of Using Term «Fitness» in the Legislation of the Russian Federation
Authors: Kovalenko Ekaterina , Tydykova Nadezhda
Published: January 2021

The article centers on the study of new concepts in the legislation of the Russian Federation on physical training and sports. The authors analyze the concept of «fitness center», whichhas appeared in the legislation quite recently. There have arisen doubts about the rationale for its use among the variety of many similar terms that are actuallyemployed, which creates difficulties in determining their correlation. It has been noted that the term «fitness» has no conventional meaning and is not traditional for Russian reality. Another option is proposed to regulate the operation of physical training and sports organizations, the purpose of which is to provide citizens with services of physical training and physical development. In the approach proposed by the authors, the text of the law should contain a general term to unify names of such organizations. Under this approach, the term «fitness center» is unnecessary. The authors have not found any reasons for introducing the term «fitness» into the text of the Russian law, although they do not exclude their appearance in the future. Many practical problems have been noted that arise due to the lack of high-quality legal regulation of the activities of organizations that provide citizens with physical training and physical developmentservices. The authors come to the conclusion that the main problem is not the name of such organizations, but the contents of the regulation of their activities. The necessity of legislative clarification of such terms as «crossfit», «aqua fitness», «fitness aerobics», «body fitness», «fitbox» and some others is analyzed. The authors note that their indtoduction  intothe text of a normative legal act is possible in order to set the rules for a particular sport or instructions for coaches, orin other similar documents. Simple placing of terms and their definitions in the text of the law is perceived as inappropriate.
E SE A MÁSCARA CAIR? FENÔMENO IMPOSTOR, CARACTERÍSTICAS PESSOAIS E BACKGROUND FAMILIAR DOS PÓS-GRADUANDOS STRICTO SENSU DA ÁREA DE NEGÓCIOS
Authors: Meurer Alison Martins , Costa Flaviano
Published: January 2021

Objetivo: Este estudo objetiva identificar os grupos de pós-graduandos stricto sensu da área de negócios que possuem níveis mais elevados de intensidade do Fenômeno Impostor (FI) a partir das características pessoais e do background familiar. Método: Foram obtidas 1.816 participações válidas que representam 11,37% da população de pós-graduandos de cursos brasileiros de mestrado acadêmico, mestrado profissional e doutorado acadêmico em Administração, Contabilidade e Economia matriculados em 2018. O FI foi mensurado por meio da escala Clance Impostor Phenomenon Scale e as variáveis de agrupamento foram: gênero, cor e etnia, modalidade de Ensino Médio, nível de escolaridade da figura materna e paterna, e por fim, geração ao ingressar no Ensino Superior e na pós-graduação stricto sensu. Os dados foram analisados por meio do teste de Kruskal-Wallis com post hoc de Mann-Whitney. Resultados: A forma como o Fenômeno Impostor é vivenciado é diferente entre os gêneros, evidenciando a importância de abordar o FI como um constructo bidimensional. Para a modalidade de Ensino Médio verificou-se que alunos de escolas particulares possuem maiores níveis de impostorismo, assim como os que a figura paterna e materna possuem ensino médio completo. Discentes da segunda geração a ingressar no ensino superior também apresentaram maior nível de sentimentos impostores, enquanto a cor e etnia e geração a ingressar na pós-graduação stricto sensu não apresentaram significância. Contribuição: A bidimensionalidade do FI, a lente da Teoria da Atribuição, a confrontação com as premissas da literatura e as considerações práticas para minimizar o impostorismo apresentam-se como as principais implicações da pesquisa.
O DISCURSO DE SUSTENTABILIDADE E A PESQUISA ACADÊMICA SOBRE RELATO INTEGRADO (IR) NO SETOR PÚBLICO
Authors: Souza Franciele Machado de , Panhoca Luiz
Published: January 2021

Objetivo: Com base na teoria do discurso de Laclau e Mouffe e na expectativa de ampliar o entendimento da sustentabilidade corporativa para que as vozes acadêmicas possam oferecer uma crítica contínua e novas alternativas para este discurso, estabeleceu-se como objetivo analisar a construção do discurso de sustentabilidade nos resultados de pesquisas sobre os Relatos Integrados (IRs) de empresas do setor público. Método: As pesquisas publicadas, que analisaram os IRs destas organizações, foram examinadas para considerar como o discurso hegemônico estava construído nos 18 artigos científicos, selecionados/identificados na base de dados Scopus com os termos “integrated reporting”, “state-owned” e “public sector”. Os estudos foram classificados quanto as suas metodologias e a forma de apropriação do discurso em torno do ponto nodal sustentabilidade.Resultados: Os resultados revelaram que o discurso de sustentabilidade presente nas pesquisas revisadas estava relacionado ao desenvolvimento econômico, à estratégia e ao “business-case”. No entanto, existem evidências a adoção ao IR tem o potencial de impulsionar a mudança organizacional para integrar a sustentabilidade à atividade principal da organização. Em suma, os achados sugerem que a adoção ao IR, por empresas do setor público, não modificou o discurso hegemônico de sustentabilidade financeira. Contribuições: Assim, o artigo contribui com a literatura de IR ao revelar a necessidade das pesquisas sobre sustentabilidade ampliarem a investigação nos relatórios, a partir de novos enfoques, análises críticas e pesquisas normativas que objetivem propor adaptações ao IR nas instituições públicas, e até propor outros frameworks.
Types of Generalization Made by Pupils Aged 12–13 and by Their Future Mathematics Teachers
Authors: Slavíčková Mária
Published: January 2021

This paper seeks to establish what kind of arguments pupils (aged 12–13) use and how they make their assumptions and generalizations. Our research also explored the same phenomenon in the case of graduate mathematics teachers studying for their masters’ degrees in our faculty at that time. The main focus was on algebraic reasoning, in particular pattern exploring and expressing regularities in numbers. In this paper, we introduce the necessary concepts and notations used in the study, briefly characterize the theoretical levels of cognitive development and terms from the Theory of Didactical Situations. We set out to answer three research questions. To collect the research data, we worked with a group of 32 pupils aged 12–13 and 19 university students (all prospective mathematics teachers in the first year of their master’s). We assigned them two flexible tasks to and asked them to explain their findings/formulas. Besides that, we collected additional (supportive) data using a short questionnaire. The supporting data concerned their opinions on the tasks and the explanations. The results and limited scope of the research indicated what should be changed in preparing future mathematics teachers. These changes could positively influence the pupils’ strategies of solving not only flexible tasks but also their ability to  generalize.

Authors: Kana Hauwa Aliyu , Kwon-Ndung Emmanuel Hala
Published: January 2021

Field study was conducted at the Botanical Garden, Federal University of Lafia, between August and October 2017 to investigate the effect of alpha nano spin on nine advanced varieties of cowpea obtained from Institute of Agriculture Research (IAR), Zaria and one local variety from Nasarawa Agricultural Development Program (NADP), Lafia which served as the control. These seeds were exposed to alpha-spin nano-particles at four different periods; 20 mins, 40 mins and 60 mins termed as T1, T2 & T3 respectively while the untreated seeds 0 mins were termed T0 (control). The experimental design was a Randomized Complete Block Design with four replications. Data were collected on agronomic traits, yield components and grain yield, which were subjected to Analysis of Variance and Principal Component Analysis. Laboratory studies were also carried out to determine the pattern of Dry matter accumulation at two weeks interval for six weeks. Results of harvested seeds revealed that Sampea 5, inoculated at 40 mins treatment produced black seeds colour from brown seed colour parent. Results also showed a significant difference among treatments and varieties for mean plant height, the mean number of leaves, mean number of pods and mean pod length. Total dry matter accumulation of leaves, 100 disc leaves and stems over time varied among treatments and varieties. The first three Principal Components (PCs) accounted for 83.1% of the total variation implying their high selection stability. The detailed results are presented and discussed in this paper as a measure of the future selection of useful variants of the improved cowpea for sustainable cowpea production.

“A coisa mais antiga de que me lembro” ou como resgatar o reino literário de Sophia: notas para uma reconstrução pedagógica do universo andreseniano
Authors: Sousa de Oliveira Elisama
Published: January 2021

A realização deste artigo resulta da conjugação de dois fatores: por um lado, da vontade de estudar os textos da Arte Poética de Sophia de Mello Breyner Andresen que, em tempos mais recentes, têm permanecido levemente esquecidos e, por outro, tendo em conta, como afirmou Mª Graciete Besse (1990), que os princípios da Arte Poética andreseniana se encontram "também nos textos em prosa" (p. 11), fazendo valer a "grande unidade temática e estilística" (Gomes, 2000, p. 11) que José António Gomes percebeu na obra da autora d´A Menina do Mar, levar a cabo um estudo comparativo que torne visíveis os reflexos dos preceitos da poética de Sophia na sua prosa narrativa destinada às crianças e jovens, apontando, de permeio, caminhos que evidenciam a utilidade pedagógica da leitura cruzada destes textos no âmbito da Educação Literária.

Why Do Intelligent People Care More About the Environment?
Authors: Poškus Mykolas Simas
Published: January 2021

The present study investigates and provides support for the Savanna-IQ interaction hypothesis regarding pro-environmental values. Study 1 showed that the highest attained education level is a significant predictor of pro-environmental concern, while Study 2 showed that the trait of openness to experience plays a unique role in predicting biospheric values, but not other values, lending support for the Savanna-IQ interaction hypothesis. Acting to preserve the natural environment is an evolutionarily novel challenge, and therefore, is more actively addressed by individuals who more readily adopt novel ideas and seek out new ways of behaving.

Published: January 2021

This study aims to determine the effect of consumption beta on Islamic stock returns. The research model used Breeden's (1979) CCAPM model by adding macroeconomic variables as control variables in the first regression test. The sample selection used a purposive sampling technique and obtained 27 active Islamic stocks listed on the JII index during 2019. The data and information collected are historical data, namely the monthly closing price of the JII Islamic stock index, Gross Domestic Product Data, Inflation data and SBI interest rates. . The use of macroeconomic variable data is an effort to obtain a Goodness of fit model so that it is able to produce estimates in accordance with the actual value. The beta coefficient value obtained in the first test then carried out the second stage regression. The results prove that there is a negative influence between consumption beta on the average yield of Islamic JII stocks of 21.56%, with a consumption variable value of -0.046894 and a significant T value of 0.0147 <0.05. Thus, this research briefly proves that the CCAPM Breeden model (1979) applies to the JII Islamic stock index on the Indonesia Stock Exchange for the period 2019.

Published: January 2021

The research aims to determine the influence of capital intensity and profitability on tax aggressiveness using the company size as moderation variables. The research object is a mining company listed on the Indonesia Stock Exchange (IDX) from 2016 to 2018. The number of companies sampled in this research was 25 companies with 3 years of observation time over selected with purposive sampling techniques. The data analysis used statistical analysis in the form of multiple linear regression tests. This study showed that simultaneously the variable capital intensity, profitability and size of the company affected the tax aggressiveness. Partial capital intensity and company size have a negative effect on tax aggressiveness, while the profitability has no effect on tax aggressiveness. Otherwise, based on the moderated regression analysis (MRA) test, the company size variable can moderate the influence of capital intensity on the tax aggressiveness. Size can not moderate the influence of profitability on the tax aggressiveness.

Credit Interest Rates do not have an effect on Return On Assets (ROA), while Credit Risk which is proxied by Net Performance Loan (NPL) has a significant negative effect on Return On Assets (ROA) and Interest Income has a significant positive effect on Return On Asset (ROA). The indirect relationship between lending rates and credit risk with Return On Assets (ROA) by using interest income as an intervening get significant results.
“Se calhar é porque existem mais brancos do que negros no mundo”
Authors: Mendonça Felipe Viero Kolinski Machado
Published: January 2021

Este artigo é resultado de uma pesquisa mais ampla que, inspirada na etnografia e a partir de entrevistas em profundidade realizadas com jornalistas e com profissionais da redação e dos discursos mobilizados em capas, em ensaios fotográficos e em reportagens/textos jornalísticos de Men’s Health Portugal e de Junior, objetivou perceber quais sentidos acerca das masculinidades, então, eram ali mobilizados. Aqui, de modo mais específico, a atenção se volta aos regimes de visibilidade que enquadram homens negros nessas revistas. A partir de referências bibliográficas que dizem dos gêneros/masculinidades, das identidades e das diferenças e das identidades negras, pergunta-se: quais lugares, a partir de seus discursos, as revistas Men’s Health Portugal e Junior reservam aos homens negros? O apagamento desses corpos ou, mais especificamente no caso de Junior, uma visibilidade regulada (hipersexualização do homem negro) são algumas das principais conclusões.

O artigo explora as materialidades digitais da informação a partir do percurso da experiência de dataficação da ansiedade e do monitoramento da respiração mediante uso do vestível Spire Stone. Apresentamos o relato de uso pessoal do wearable e uma análise descritiva da trajetória de produção informacional na associação corpo-algoritmos-vestível. Argumentamos que as materialidades da informação se referem menos às essências representacionais (soft) ou materiais (hard) do vestível-plataforma, e mais às cadeias de ação e às consequências práticas produzidas durante a experiência de monitoramento. Sugerimos a noção de experiência em William James como abordagem complementar aos estudos que optam por explorar as materialidades digitais da informação no processo dinâmico de sua própria formação, evitando perspectivas centradas na especificidade técnica dos objetos inteligentes ou restritas à percepção humana sobre o uso deles.
Variación de los precios de la naranja (Citrus sinensis L.) en México
Authors: García-Salazar José Alberto , Bautista-Mayorga Fidel , Borja-Bravo Mercedes , Guzmán-Soria Eugenio
Published: January 2021

Introducción. Identificar los factores que pueden aumentar los precios al productor de naranja es importante por los efectos negativos que una caída en el ingreso puede tener sobre los productores agrícolas. Objetivo. Determinar cómo la demanda de la industria y la superficie sembrada de naranja afectan los precios al productor, al consumidor y al mayoreo. Materiales y métodos. Se formuló un modelo sintético del mercado de la naranja en México que consideró la producción en superficies de riego y temporal (ciclo de lluvia), la demanda en fresco e industrial,y diferentes niveles de transmisión de precios. El modelo replicó el valor promedio de las variables más importantes en el mercado de la naranja de los años 2014-2016. Resultados. Un aumento de 5 % en el consumo de la industria productora de jugo de naranja haría crecer los precios al productor en superficies de riego y bajo temporal en 11,1 y 35,8 %, respectivamente, y ubicaría los precios al mayoreo 31,7 % por encima de los precios observados en la situación base. Una disminución de 5 % en la superficie cosechada de naranja tendría un aumento de 15,2 y 49,1 % en el precio al productor en zonas de riego y temporal, con relación a la situación base. Conclusión. La superficie y la demanda industrial son medidas de control que pueden evitar la caída de los precios. Por la importancia que la producción de naranja tiene para los productores, el gobierno debería promover medidas para evitar que el aumento en la superficie de naranja provoque la disminución de los precios y lograr el compromiso de la industria de actuar a través de la demanda en situaciones de emergencia, es decir en los años de exceso de oferta de naranja.
Normalization by second order graphs: A visual alternative to simplify systems
Authors: Muñoz Garro Edward
Published: January 2021

This issue stems from the need for tools to analyze and make decisions around complex systems, where they apply the rules for linearly dependent sets, with the purpose of providing a visual tool, which serves to support complexity reduction processes. Two great precedents are Armstrong's Axioms, which has been applied from its publication to the present for database normalization, the other is set theory, a fundamental pillar of the Structured Query Language; based on them, together with the second-order logic, which adds qualifiers for subsets or properties, this work has been prepared, with an explanatory metrology with a qualitative approach, in an axiomatic system. As a result, a support tool has been provided to analyze complex systems naturally, by breaking cycles and detecting patterns, without interfering with existing models; however, for large systems it can be difficult to address it in its entirety, so it is recommended to divide by subsystems. With this work a technique has been accomplished, repeatable by anyone, but with a strong theoretical foundation. This work has great utility for the normalization of relational databases and an enormous potential for application in the design of systems beyond computational systems, it is also useful for understanding dependencies by their axiomatic nature.

Model of influence of AT1, AT2 type receptors on smooth muscle contractions
Authors: Yankov K. , Shivacheva G.
Published: January 2021

In the present work, the role of AT1 and AT2 receptors in the performance of angiotensin II-mediated processes has been analyzed. The involvement of each of the receptor types in regulation is determined by their separate exclusion from the feedback chain applying a suitable blocker. The resulting muscle contractions are modeled with a second-order differential equation. The transfer functions in the Laplace domain and state-space models of the contractions are derived from the models. The analysis of the models justifies the determination that AT1 type receptors participate in positive feedback and those of AT2 type in negative.

Authors: Surijah Edwin Adrianta , Prasetyaningsih Ni Made Mitha , Supriyadi Supriyadi
Published: January 2021

Love is an essential part of human experience and love languages have been studied to validate its factors’ structures to explain what makes people feel loved. The current study addresses the gap that love research shall not rely on student samples and it needs to measure the actual outcome of love languages. This study aims to gather empirical evidence for love languages’ factor structure and its relation to the outcome variable. The method for this study is a quantitative survey with 250 couples reported their love languages using a rating-scale and forced-choice scale. The data analysis examined the factor structure of the love languages model and estimated the association between love languages compatibility and marital satisfaction. The factorial analysis showed that the five factors solution was not supported and love languages compatibility did not affect couples’ marital satisfaction. This result brought discussions on how popular psychology concepts need to be under the scrutiny of scientific investigation and that different contexts may have different factors on what makes people feel loved.

Milestones in Bacillus subtilis sporulation research
Authors: Riley Eammon P. , Schwarz Corinna , Derman Alan I. , Lopez-Garrido Javier
Published: January 2021

Endospore formation has been a rich field of research for more than a century, and has benefited from the powerful genetic tools available in Bacillus subtilis. In this review, we highlight foundational discoveries that shaped the sporulation field, from its origins to the present day, tracing a chronology that spans more than one hundred eighty years. We detail how cell-specific gene expression has been harnessed to investigate the existence and function of intercellular proteinaceous channels in sporulating cells, and we illustrate the rapid progress in our understanding of the cell biology of sporulation in recent years using the process of chromosome translocation as a storyline. Finally, we sketch general aspects of sporulation that remain largely unexplored, and that we envision will be fruitful areas of future research.
Adam Small, Kanna en ‘daardie morele moment’
Authors: Van Zyl Wium
Published: January 2021

This essay revisits Adam Small’s best known play Kanna hy kô hystoe (“Kanna he comes home”, 1965) in order to evaluate its relevance for contemporary readers and audiences. The text, considered one of the classics of Afrikaans literature, is analysed from a rhetorical point of view. The analysis includes an overview of several pertinent academic studies on the play, a summary of the play’s sociopolitical context, and a brief background to rhetorical analysis. The article further takes account of the author’s struggle with his prevailing cultural and political environment before and during the writing and publication of the play, as well as the drawn-out period of five years before its eventual first professional performance, and its subdued reception by prominent Afrikaans literary critics. The second part of the article involves the identification and analysis of three rhetorical problems presented in the play: “Did Kanna act unethically by not returning ‘home’ after his studies?”; “Did Dickie deserve his death sentence?”; and “Who was responsible for creating the wretched circumstances which Makiet, who had always been caring, had to endure?”
