On Fully Prime Radicals
Authors: Wijayanti Indah Emilia , Yuwaningsih Dian Ariesta
Published: April 2021

In this paper we give a further study on fully prime submodules. For any fully prime submodules we define a product called $\am$-product. The further investigation of fully prime submodules in this work, i.e. the fully m-system and fully prime radicals, is related to this product. We show that the fully prime radical of any submodules can be characterize by the fully m-system. As a special case, the fully prime radical of a module $M$ is the intersection of all minimal fully prime submodules of $M$.
Further Remarks on n-Distance-Balanced Graphs
Authors: Faghani Morteza , Pourhadi Ehsan
Published: April 2021

Throughout this paper, we present a new strong property of graph so-called nicely n-distance-balanced which is notably stronger than the concept of n-distance-balanced recently given by the authors. We also initially introduce a newgraph invariant which modies Szeged index and is suitable to study n-distance-balanced graphs. Looking for the graphs extremal with respect to the modiedSzeged index it turns out the n-distance-balanced graphs with odd integer n arethe only bipartite graphs which can maximize the modied Szeged index and thisalso disproves a conjecture proposed by Khalifeh et al. [Khalifeh M.H.,Youse-Azari H., Ashra A.R., Wagner S.G.: Some new results on distance-based graphinvariants, European J. Combin. 30 (2009) 1149-1163]. Furthermore, we gathersome facts concerning with the nicely n-distance-balanced graphs generated by somewell-known graph products. To enlighten the reader some examples are provided.Moreover, a conjecture and a problem are presented within the results of this article.
Morrey Spaces are Embedded Between Weak Morrey Spaces and Stummel Classes
Authors: Tumalun Nicky , Gunawan Hendra
Published: April 2021

In this paper, we show that the Morrey spaces $ L^{1,\left( \frac{\lambda}{p} -\frac{n}{p} + n \right) } \left( \mathbb{R}^{n} \right) $ are embedded betweenweak Morrey spaces $ wL^{p,\lambda}\left( \mathbb{R}^{n} \right) $ and Stummelclasses $ S_{\alpha}\left( \mathbb{R}^{n} \right) $ under some conditions on$ p, \lambda $ and $ \alpha $. More precisely, we prove that $ wL^{p,\lambda}\left(\mathbb{R}^{n} \right) \subseteq L^{1,\left( \frac{\lambda}{p} - \frac{n}{p} + n\right) } \left( \mathbb{R}^{n} \right) \subseteq S_{\alpha}\left( \mathbb{R}^{n}\right) $ where $ 1<p<\infty, 0<\lambda<n $ and $ \frac{n-\lambda}{p}<\alpha<n $.We also show that these inclusion relations under the above conditions are proper.Lastly, we present an inequality of Adams' type \cite{A}
Character Table Groups and Extracted Simple and Cyclic Polygroups
Authors: Sekhavatizadeh Sara , Zahedi Mohammad Mehdi , Iranmanesh Ali
Published: April 2021

Let G be a finite group and \hat{G} be the set of all irreducible complex characters of G. In this paper, we consider <\hat{G}, *> as a polygroup, where for each chi_i ,chi_j in \hat{G} the product \chi _{i} * \chi_{j} is the set of those irreducible constituents which appear in the element-wise product \chi_{i} \chi_{j}. We call that \hat{G} simple if it has no proper normal subpolygroup and show that if \hat{G} is a single power cyclic polygroup, then \hat{G} is a simple polygroup and hence \hat{S}_{n} and \hat{A}_{n} are simple polygroups. Also, we prove that if G is a non-abelian simple group, then \hat{G} is a single power cyclic polygroup. Moreover, we classify \hat{D}_{2n} for all n. Also, we prove that \hat{T}_{4n} and \hat{U}_{6n} are cyclic polygroups with finite period.

Published: April 2021

Cyberspace crime is a critical threat to the information security of the state and civil society institutions. Inside global network the abuse of computer user’s trust allows organized criminal groups to achieve their economic and political goals by committing offenses in the international information space. The methods of participatory observation, comparative legal and discourse analysis show that digital transformation has weakened the influence of the state on the development of the cultural sphere of society, and computer technologies have become the object of interests of criminal structures. Digital transformation has created virtual reality based on the laws and regulations of the networked community. Civil society by rejecting most of the peremptory norms imposed by national governments for political purposes produce victims of a wide range of cybercrimes: fraud and computer misuse offences and obscene publications. Since digital transformation is a universal phenomenon that will inevitably change the life of the entire world community, it is necessary to reach a consensus on the development and implementation of modern international agreement which, on the one hand, will guarantee freedom of speech and the right of every person to access information, and on the other hand will protect citizens, states and social institutions from criminal encroachments in an actively developing digital environment.

Authors: Bampali Konstantina , Koniuszewski Filip , Silva Luca , Rehman Sabah , Vogel Florian , Seidel Thomas , Zirpel Florian , Garon Arthur , Langer Thierry , Willeit Matthäus , Ernst Margot
Published: April 2021

Background and Purpose: Many psychotherapeutic drugs including
clozapine have a polypharmacological profile and act on
GABA receptors, where subtype-specific information is
often lacking. Patients with schizophrenia show alterations in function,
structure and molecular composition of the hippocampus, and a recent
study demonstrated aberrant levels of hippocampal α5 subunit containing
GABA receptors. Experimental Approach:
Functional studies of GABA modulatory effects by antipsychotic and
antidepressant medications were performed in several
GABA receptor subtypes by two‐electrode voltage‐clamp
electrophysiology using Xenopus laevis oocytes. Computational
structural analysis was employed to design mutated constructs of the α5
subunit, probing a novel binding site. Computational ligand analysis
complemented the functional and mutational data. Key Results:
We show that the antipsychotic drugs clozapine and chlorpromazine have
negative modulatory effects on multiple GABA receptor
subtypes, including α5-containing. On the latter we show negative
modulatory effects for five additional antipsychotic and antidepressant
drugs. Based on a chlorpromazine binding site observed in a GABA-gated
bacterial homologue, we identified a novel site in α5
GABA receptor subunits. Conclusion and
Implications: Our findings support previous studies suggesting a link
between some of the therapeutic effects of clozapine and its negative
modulatory action on certain GABA receptor subtypes.
The novel site we describe in this study is a new potential target for
optimizing antipsychotic medications with beneficial polypharmacology.

Published: April 2021

Abstract Background: Graft-versus-host disease (GVHD) is a common and
undesirable complication of hematopoietic cell transplant (HCT) for
non-malignant disorders (NMD). Understanding the incidence and risk
factors for GVHD in children with NMD is an important step in developing
strategies for its prevention. Study Design: This is a retrospective,
registry, study that included children with NMD receiving HCT in 5
centers in Florida between 2010 and 2019. Results: Among 183 patients
evaluable for GVHD, acute GVHD (aGVHD) grades I, II, III, and IV were
present in 18%, 12.6%, 3.8% and 5.5% of patients, respectively.
Limited and extensive chronic GVHD (cGVHD), were observed in 8.7% and
12.6% of patients. Patients with aGVHD grade III/IV had significantly
lower 3-year survival rates than those without aGVHD, or those with
aGVHD grade I/II (52.9% [95% confidence interval (CI) 34-83] vs.
90.1% [95% CI 84-96], vs. 98.1% [95%CI 95-100],
p<0.001). Patients without cGVHD and those with limited and
extensive cGVHD had 3-year survival rates of 88.9% [95%CI 84-94],
91.7% [95%CI 77-100], and 84.8% [95%CI 70-100],
respectively, log rank p=0.3. Receiving transplant from an
HLA-mismatched unrelated donor (MMUD), as compared to a matched related
donor (MRD), increased the risk for aGVHD grade III/IV (Odds ratio 10.4
[95% CI 2.5-47.6]). There were no cases of aGVHD grade III/IV among
recipients of mismatched related/haploidentical transplants.
Conclusions: Grade III/IV aGVHD, which significantly reduced overall
survival, was reported in 9.3% of children with NMD receiving HCT. Risk
factors included HCT from a MMUD but not mismatched related donors.

Si presenta una delle autorizzazioni necessarie in termini di rispetto
ambientale, l’Autorizzazione Unica Ambientale (AUA), ovvero una
procedura che semplifica la richiesta dei titoli autorizzativi ai fini
di esercitare la propria attività. Questa procedura è stata prevista
come risposta alla richiesta delle imprese di facilitare i procedimenti
attinenti ad una molteplicità di autorizzazioni e comunicazioni in
materia ambientale, per il tramite del Suap, mantenendo un elevato
livello di tutela ambientale.

Oggi è fondamentale parlare di ambiente ed in particolare di rispetto
per esso. Dal punto di vista normativo, in Europa, si sta cercando di
“essere sensibili” alla salute del pianeta. Per poter raggiungere
l’obiettivo prefissato, tale sensibilizzazione deve avvenire in ogni
campo. Una delle categorie più “colpite” è, infatti, quella edilizia.

L’AUA, perciò, risulta essere necessaria ai fini del perseguimento
dell’obiettivo definito in precedenza.
An Investigation of the Readability of Sustainability Reports
Authors: Uddin Nancy , Chakraborty Vasundhara
Published: April 2021

Requirement of G4 standards as common practice in sustainability reporting makes it important to understand the readability of such reports. This study contributes to the extant body of literature by assessing the readability of sustainability reports. We investigate several factors such as company size, company age, complexity, domestic versus international, and audited versus unaudited reports and how they contribute to the readability of sustainability reports. We apply text analytics to U.S. and Global firm issued sustainability reports. We also provide evidence about factors that may contribute to the readability of sustainability reports. We find that reports of companies in regulated industries are less readable than other firms' reports. We also find that less complex firms have more readable sustainability reports. This study should provide some insights to users of sustainability reports, standard setters for reporting standards, and for future researchers.
Expected Stock Returns Worldwide: A Log-Linear Present-Value Approach
Authors: Chattopadhyay Akash , Lyle Matthew R. , Wang Charles C. Y.
Published: April 2021

This study provides the first large-scale study of the performance of expected-return proxies (ERPs) internationally. Analyst-forecast-based ICCs are sparsely populated and not robustly associated with future returns. Earnings-model-forecast-based ICCs are well-populated, but are unreliable outside the U.S. We adapt and extend the log-linear and present-value (LPV) framework—combining an accounting valuation anchor, its expected growth, and market prices—for estimating ERPs internationally, and implement a correction for the use of stale accounting data. An LPV ERP anchored on the book value of equity is positively associated with future returns in 26 of 29 equity markets, and largely subsumes the predictive ability of a broad set of firm characteristics previously shown to be associated with expected returns.

Foreign Employment, Income Shifting, and Tax Uncertainty
Authors: Drake Katharine D. , Goldman Nathan C. , Murphy Francis
Published: April 2021

We examine the effect of foreign employment on two outcomes—income shifting and the tax uncertainty of foreign transactions. Using a hand-collected sample of employment disclosures, we partition our sample into firm-years with a higher or lower degree of foreign employment. Using two distinct income shifting models, we document that, on average, a high degree of foreign employment is associated with greater tax-motivated income shifting out of the U.S. We also posit and find that a high degree of foreign employment enhances the economic substance of foreign transactions, reducing the tax uncertainty associated with foreign income. We conduct additional analyses to mitigate selection bias concerns, and we use exogenous changes to the costs and benefits of income shifting using foreign employment to strengthen identification. Our results highlight firms' use of employees as part of a tax-efficient supply chain and how foreign employment enhances income shifting opportunities between jurisdictions.
The Role of Peer Events in Corporate Governance: Evidence from Data Breaches
Authors: Ashraf Musaib
Published: April 2021

Economic theory suggests that negative peer events can result in market-wide spillovers that help unaffected firms take real actions to enhance corporate governance. Motivated by the SEC's concern about cybersecurity, I study the role of peer events in corporate governance using the setting of data breaches. While controlling for firm-specific time-varying unobservable characteristics, I find that peer data breaches are associated with a reduction in future internal control material weaknesses for non-breached firms. The association is robust to a changes analysis and varies cross-sectionally with breach, firm, and board characteristics. Inferences remain consistent when studying IT-related material weaknesses only. Finally, non-breached firms are more likely to have a cybersecurity expert on the top management team after a peer breach. My findings have important implications for mandatory disclosure regulation in general and, in particular, suggest that regulators can help reduce market-wide exposure to cyber risk by facilitating disclosure of cyber incidents.

This article explores the meaning and function of streaming media as a potential facilitator of musicalBildung. Taking the affordances of streaming media technologies as a starting point, the article thusfocuses on the formative and cultivating dimensions a music streaming service such as Spotifymight offer. The specific aim of this article is to describe and analyse how musical Bildung may evolvewithin a Spotify context from a user perspective. To address the aim from the point of view of musiceducation, Spotify users’ activities and experiences of streaming media interactions were accessed,inspired by internet-related ethnography. Stimulated recall interviews, focusing on the participants’experiences as well as their actual use of Spotify’s streaming service, were conducted, recorded, andtranscribed. The generated material was subjected to co-operative hermeneutic content analysis.The results illuminate how Bildung evolves in users’ encounters with the service and with art mediatedvia Spotify. Relevant topics occurring in the human-art-technology relationship of Bildung from aHeideggerian perspective were Being-possible, the ability-to-be, and Spotify as the Other. In sum, itcan be stated that Bildung evolves when Spotify exceeds the thingness of the Other, becoming a workof art in itself, throwing the user into Being.
The “operatic of opera” in music history pedagogy – exploring the temporal narrativization of opera
Authors: Hautsalo Liisamaija , Westerlund Heidi
Published: April 2021

This study suggests that the pedagogy of music history for the professional training of musicians –including opera singers and future opera composers – could benefit from applying narratologyto operatic analysis and acknowledging the “operatic of opera” in the organization of the artisticmaterials as one possible pedagogical approach. By breaking with the canonized forms of musichistory pedagogy, the subject content of opera history can be explored for instance through thearchitecture of temporal narrativization, as made possible by the multiple media types incorporatedinto opera. The study demonstrates this temporal narrativization through examples grouped into threemain categories: “temporal sameness”, “temporal incongruence” and “non-linear temporality”. Whilemost of the examples are drawn from the classical-romantic repertoire, the analysis also shows thatnew pluri-medial ways of dealing with temporality and narration have been emerged in contemporaryopera. The study argues that by analyzing and illustrating the architecture of temporal narrativizationas one form of the “operatic of opera” in Western operatic practice, students will gain a betterunderstanding of the special nature of the pluri-medial nature of opera.
Mapping the Spatial Variability of Sexually Transmitted Infections Across Fiji Health Regions
Authors: Shah Tayyab , Sidloski Michaela , Toroca Elisa
Published: April 2021

Introduction: Sexually transmitted infections (STIs) are a significant public health problem in countries within the South Pacific, including Fiji. If untreated, curable STIs such as chlamydia, gonorrhea, and syphilis can cause infertility, adverse outcomes in pregnancy, and can increase the risk of contracting HIV in infected individuals.

Methods: This research used cartographic software to map and analyze the spatial distribution of selected STIs across health regions in Fiji. Total rates of STIs, as well as the prevalence of gonorrhea and syphilis specifically, were examined for the years of 2007 and 2016 to determine how spatial distribution patterns have changed over this period, and how resources might currently be most effectively mobilized to address this public health issue.

Results/Discussion: Our findings suggest that while some specific regions with high prevalence rates for 2007 and 2016 should be targeted for intervention in the short term, lack of data collecting and reporting raises concerns about the accuracy of rate estimations in non-urban areas.

Conclusion: Analyzing the spatial distribution of the prevalence of STIs in a given population can better inform the development and implementation of intervention strategies at local scales, thus improving health outcomes for countries and their communities. Overall, consistent and transparent STI data collection and reporting procedures are necessary for effective long-term management and minimization of STI spread in Fiji.

Published: April 2021

Current pharmaceutical research directions tend to follow a systematic approach in the field of applied research and development. The concept of quality-by-design (QbD) has been the focus of the current progress of pharmaceutical sciences. It is based on, but not limited, to risk assessment, design of experiments and other computational methods and process analytical technology. These tools offer a well-organized methodology, both to identify and analyse the hazards that should be handled as critical, and are therefore applicable in the control strategy. Once implemented, the QbD approach will augment the comprehension of experts concerning the developed analytical technique or manufacturing process. The main activities are oriented towards the identification of the quality target product profiles, along with the critical quality attributes, the risk management of these and their analysis through in silico aided methods. This review aims to offer an overview of the current standpoints and general applications of QbD methods in pharmaceutical development.
Mathematical Analysis of the Influence of the Flux-Cored Wire Chemical Composition on the Electrical Parameters and Quality in the Underwater Wet Cutting
Authors: Parshin S. , Levchenko A. , Wang P. , Maystro A.
Published: April 2021

The paper presents research in the field of underwater wet cutting with the use of flux-cored wires in order to improve the quality and performance. The research has resulted into the development of gas and slag systems for flux-cored wires and determination of, optimal parameters for cutting stability and quality. The underwater wet cutting mechanism is a cyclical process with the formation of periodic keyholes in metal, and it consists of operating and idle cycles. Efficiency of the cutting process can be determined by analyzing cycle times, welding current, voltage, power and a number of short circuits. To assess the stability and efficiency of the underwater wet cutting process, the authors have developed the method for analyzing oscillograms to calculate the probability density of current, voltage and power. To determine the quality of cutting, the authors have provided a criterion based on the ratio of the voltage probability density in the idle and operating cycles.

Published: April 2021

With the increase in consumers’ concern for safe food, it is highly imperative for livestock farmers to adopt feeding practices that enhance good health and high-quality products. A 49-day trial was conducted to ascertain effect of vitamin E and selenium (VE + Se) on performance, haematological indices and oxidative stability of chicken meat. A total of 150 Ross 7-day-old chicks were weighed and allotted to five treatments comprising dietary levels of 0 mg VE + 0 mg SE (Control), 100 mg VE + 0.05 mg Se, 200 mg VE + 0.1 mg Se, 300 mg VE + 0.15 mg Se and 400 mg VE + 0.2 mg Se per kg of feed in a completely randomised design. Feed and water were provided ad libitum. The data collected on performance, haematological indices and oxidative stability of meat were subjected to a one-way analysis of variance in a completely randomised design. Performance indices were significantly (p < 0.05) influenced by VE + Se supplementation. Mean daily live-weight gain (48.68 g /bird /day) was highest (p < 0.05) in the 400 mg VE + 0.2 mg group. The mean daily feed intake (g /bird / day) was highest in birds fed the diet containing 200 mg VE + 0.1 mg. The least or best feed conversion ratio (FCR) was observed in the group fed 400 mg VE + 0.2 mg SE. Glutathione peroxidase (GSH-Px) increased as the level of VE + Se increased with the highest activity in 400 mg VE + 0.2 mg Se group. The highest packed cell volume, haemoglobin and red blood cell values were observed in birds fed the diet containing 400 mg VE + 0.20 mg Se. In conclusion, to ensure good performance of the chickens and improved oxidative stability of chicken meat in hot climate, feeding broilers VE + SE at 400 mg VE + 0.2 mg Se is recommended.

Authors: Akinyele O. F. , Ikujenlola A. V. , Omobuwajo T. O.
Published: April 2021

Pupuru and pupuru analogues are fermented, smoked food products usually produced from cassava or cassava substituted with a varying ratio of breadfruit. This study aims at determining and comparing the functional and pasting characteristics of pupuru and pupuru analogues with a view to expanding the utilization of breadfruit as pupuru analogue. The functional properties (water absorption capacity (%), swelling power (g/g), solubility (%)) and pasting characteristics were determined using standard methods. The results showed that the yield of the products ranged between 24.66 and 29.65%, and it was not affected by the amount of breadfruit substituted. The water absorption capacities of the pupuru and pupuru analogues ranged between 216.0 and 449.0%; this parameter increased with temperature increase. Both swelling power and solubility had a rapid increase from 80 °C to 90 °C. Pasting temperature ranged between 73.15 and 83.66 °C, with peak time between 4.58 and 5.33 min. The final viscosity ranged between 94.08 and 391.83 RVU, and it decreased with increase in breadfruit substitution. The study concluded that adding breadfruit to cassava in pupuru analogue production improved some of the functional and pasting properties of the product.

Published: April 2021

The analysis of movement patterns through EMG activity provides the opportunity to identify the muscle groups most involved in a particular exercise, and to determine the scope of inter-limb deficiencies. The aim of the present study was to investigate the effects of a side-to-side muscle activity asymmetry between the left and the right lower limb during sprinting in soccer players. Sixteen professional soccer players took part in the study. Their age, body mass and body height equaled 23.7 ± 7.6 years, 81.2 ± 10.8 kg and 179.3 ± 12.2 cm, respectively. The sprint test consisted of two maximal sprints over 30 m with a 5-min rest interval between each sprint. EMG was recorded bilaterally from the quadriceps, hamstrings and gluteal muscles. Regression analysis revealed a significant effect of a side-to-side average muscle activity asymmetry between the left and right hamstring (LH/RH) muscles during the speed tests at 5 m (p = 0.044), and 30 m (p = 0.045), as well as the left and right glutes (LG/RG) at 5 m (p = 0.044) and 30 m (p = 0.043). Our results indicate that hamstring and glute muscles should be selectively and additionally activated during resistance training in soccer players to prevent injuries and improve sprint performance.
Key Points of the Management System for the Safety of Passengers Travelling with Low-Pressure Trains
Authors: Stryhunivska Olena , Gdowska Katarzyna , Rumin Rafał
Published: April 2021

Due to the innovation of transport means based on hyperloop technology, the correctness of its functioning should be investigated in relation to many technical, economic and operational factors. This paper presents an analysis of the hyperloop technology from the point of view of ensuring safety of passengers while travelling in a low-pressure rail tunnel. The main subject of research was the design of hyperloop station infrastructure and the safety management system that will ensure the safety of passengers at the station in the sphere of atmospheric pressure, despite the station’s interaction with low-pressure tubes during entry and exit of the capsules. The safety management system also includes evacuation of passengers from low-pressure tubes in an emergency situation. The paper reviews the key issues of passenger safety in the hyperloop transport system, which are the source of justified and unfounded people’ fear of using this transport means despite its obvious advantages. The authors’ original achievement is the identification of critical points of passenger safety during their stay in the station area and during their journey through a low-pressure tunnel, as well as the design of a double airlock that can be used in the hyperloop tunnel at repeatable intervals with the aim of evacuating passengers to the atmospheric pressure zone. The designed solution allows to eliminate one of the significant weaknesses of the transport system using low-pressure rail.
An overview of hepatocellular carcinoma with atypical enhancement pattern: spectrum of magnetic resonance imaging findings with pathologic correlation
Authors: Kovac Jelena Djokic , Ivanovic Aleksandar , Milovanovic Tamara , Micev Marjan , Alessandrino Francesco , Gore Richard M.
Published: April 2021

Background

In the setting of cirrhotic liver, the diagnosis of hepatocellular carcinoma (HCC) is straightforward when typical imaging findings consisting of arterial hypervascularity followed by portal-venous washout are present in nodules larger than 1 cm. However, due to the complexity of hepatocarcinogenesis, not all HCCs present with typical vascular behaviour. Atypical forms such as hypervascular HCC without washout, isovascular or even hypovascular HCC can pose diagnostic dilemmas. In such cases, it is important to consider also the appearance of the nodules on diffusion-weighted imaging and hepatobiliary phase. In this regard, diffusion restriction and hypointensity on hepatobiliary phase are suggestive of malignancy. If both findings are present in hypervascular lesion without washout, or even in iso- or hypovascular lesion in cirrhotic liver, HCC should be considered. Moreover, other ancillary imaging findings such as the presence of the capsule, fat content, signal intensity on T2-weighted image favour the diagnosis of HCC. Another form of atypical HCCs are lesions which show hyperintensity on hepatobiliary phase. Therefore, the aim of the present study was to provide an overview of HCCs with atypical enhancement pattern, and focus on their magnetic resonance imaging (MRI) features.

Conclusions

In order to correctly characterize atypical HCC lesions in cirrhotic liver it is important to consider not only vascular behaviour of the nodule, but also ancillary MRI features, such as diffusion restriction, hepatobiliary phase hypointensity, and T2-weighted hyperintensity. Fat content, corona enhancement, mosaic architecture are other MRI feautures which favour the diagnosis of HCC even in the absence of typical vascular profile.
Who Is Considered Well Integrated? A Vignette Study About the Perception of Integration of Migrants
Authors: Pap Ilona
Published: April 2021

This contribution examines the relevance of the cultural, social and structural dimension of integration for the total perception of integration of migrants by the population of Switzerland. By means of a vignette study we show in our model that language ability as an aspect of cultural integration is the strongest determinant for a positive perception of integration. Second is the social integration as measured by the participation in associations, followed by the structural integration. Nationality and religion have only little relevance.
Supporting Student Visualization of Molecular Processes Through Diagram Drawing
Authors: Thachet Tara , Mullally Martha
Published: April 2021

Historically, scientists and researchers have accompanied their observations with drawings, indicating that visual models are an effective way of communicating science. Studies have shown that students should draw images that are either interpretational or transformative, and artistic ability is irrelevant as they still help improve learning. However, many educators do not utilize this practice in their courses. In this study, we investigated if practising making simple and schematic drawings can help students understand complex molecular processes, and to use that tool to contextualize complex plant biology processes in an undergraduate plant biology course. When students were introduced to a complex plant process, the instructor accompanied their explanation with a simple schematic drawing. Students were told by the instructor that 1-2 drawing questions would appear on the midterm. For the final exam, no questions explicitly asked students to include a schematic drawing. Students who drew often scored higher on questions related to the topics where drawings were introduced in the course and the lab. Students who drew on the final exam did 12.3% better on the exam than those who didn’t draw. Students who had continuous exposure to drawing style questions during the midterms, did 6% better in the course compared to students who did not write the midterms. Students also gave an overwhelmingly positive response towards drawing, and 94% of the surveyors believed that making simple drawings helped with their learning of complex molecular processes. This could indicate that exposure to drawing style questions helped reinforce the learning of complex molecular processes.

Compliance with hand hygiene standards remains a challenge to many healthcare workers even though there is adequate scientific evidence supporting its role in improving health provider and patient safety, reducing costs and creating a positive working environment. This article describes factors that contribute to non-compliance with hand hygiene standards among nurses in Windhoek, Namibia. A non-experimental, quantitative descriptive and cross-sectional design was utilised. The target population consisted of nurses working at one state-owned hospital in Windhoek. A probability, stratified random sampling method was used to select a representative sample of 170 nurses from three categories of nurses, namely registered nurses, enrolled nurses and auxiliary nurses. A self-administered questionnaire was used to collect data, which were analysed by using SPSS version 23.0. According to the results, there were more institutional than personal factors that contribute to non-compliance with hand hygiene standards among the nurses. Institutional factors included inadequate resources for hand hygiene, the absence of role models such as colleagues and supervisors, workshops, seminars and continuing educational courses on hand hygiene as well as the absence of incentives or encouragement for compliers and sanctions against non-compliers with hand hygiene standards. The key recommendations included organisational commitment to hand hygiene, the creation of an organisational climate and culture that support hand hygiene, supervision and monitoring of hand hygiene, the supply of hand hygiene agents that do not cause skin dryness, and in-service education that focuses on hand hygiene.
