Authors: Bonsu Emmanuel Mensah , Baffour-Koduah Daniel
Published: May 2023

The advent and development of technologies such as artificial intelligence have created benefits and challenges for educational stakeholders. Artificial intelligence, such as OpenAI’s Chat Generative Pre-trained Transformer (ChatGPT), has brought new benefits, challenges and pressures for higher educational institutions. There are relatively few reports of how students perceive and intend to use ChatGPT. Taking cognizance of these, the research explored students’ perceptions and intentions to use ChatGPT in their higher education. Guided by two hypotheses and a mixed-method approach, the analysis revealed no statistical relationship between perception and intention to use ChatGPT. Despite this statistical relationship, the study reported students’ positive perceptions towards ChatGPT, and intentions to use ChatGPT and advocated its adoption in education. Based on these findings, the study offers implications for educational practices and further research.

Drivers and Constraints of Employee Satisfaction with Remote Work: An Empirical Analysis
Authors: Atobishi Thabit , Nosratabadi Saeed
Published: May 2023

Background/Purpose

The Covid 19 epidemic has forced many organizations to move to remote work (RW), and this trend is expected to continue even later in the post-epidemic period. Employees of the organization are at the heart of this transi-tion to RW, so identifying the factors that affect employee satisfaction with RW is very important for organizations to increase employee commitment and motivation. Therefore, the main objective of this study was to identify and prioritize the factors affecting employee satisfaction with RW using an innovative method.

Method

In the first phase of this study, a conceptual research model was designed inspired by literature. In the next phase, the proposed conceptual model of this re-search was tested using structural equation modeling (SEM). Then, using the artifi-cial neural network model, the importance of each of the model variables in pre-dicting employee satisfaction with RW was identified.

Results

The findings of this article ultimately disclosed that work-life balance, in-stitutional and technological support, job satisfaction, and perceived limited com-munication are, respectively, are elements that affect employee satisfaction with RW. The first three factors are drivers of employee satisfaction and the last factor (i.e., perceived limited communication) is the constraint of employee satisfaction with RW because it had a statistically significant negative effect on employee satis-faction with RW.

Conclusion

This study revealed that organizations should focus on the processes and strategies to improve employees’ work-life balance, provide institutional and technological support during remote work, and increase job satisfaction in order to increase the satisfaction level of their employees in the remote work. On the other hand, it was found that perceived limited communication is an effective factor that causes a decrease in the level of satisfaction of employees in remote work.

Investigation of the Youth Informal Entrepreneurship Landscape in South Africa
Authors: Murozvi Simbarashe , Adams Charles , Yu Derek
Published: May 2023

Introduction: The South African economy is characterised by high and continuously rising youth unemployment levels and rates. While countervailing interventions have been attempted in the formal sector, support for youth employment and informal sector entrepreneurship has received limited attention from policymakers.
Purpose: This is a rare study that examined South African youth entrepreneurship by analysing all five available waves of the seriously under-utilised Survey of Employers and Self-Employed (SESE) data, focusing on youth entrepreneurial activities.
Methodology: Youth (15–34 years) and adult (at least 35 years old) informal entrepreneurs were distinguished, before deriving descriptive statistics on business activities, with a specific focus on site of operation, management, employment and net profit use in youth-owned enterprises.
Findings: Youth informal entrepreneurs were typically African own-account workers without matric (senior certificate), and operated in the wholesale and retail industry. They had decent access to electricity and piped water on the business site, but did not have e-mail or internet facilities. More than 80% did not keep any business records, while only 60% operated their businesses for the full 12 months. Nearly 90% had launched their informal businesses less than five years ago, primarily because they were unemployed. The majority needed assistance mostly in the areas of marketing, provision of an alternate site and better access to raw materials. Lastly, the majority of them spent the net profit to purchase household items instead of re-investing in the businesses.
Originality/value: The empirical findings help the government to embark on new policy changes to better promote youth informal entrepreneurship growth.
The Influence of Penalties on the Tax Compliance Behaviour of Small Business Owners
Authors: Ndlovu Mphagahlele , Schutte Danie
Published: May 2023

Purpose: The purpose of this study was to investigate the influence of penalties on the tax compliance behaviour of small business owners.
 
Research design: This study employed a qualitative research approach. An interpretive phenomenological research approach underpinned the study design. The study utilised semi-structured interviews to explore the lived experiences of small business owners in Gauteng, which is the business hub of South Africa.
 
Findings: The findings indicate that to an extent, penalties do encourage small business owners to pay taxes on time. However, the charging of substantial penalties has the potential to discourage small business owners from registering at all for taxes. Furthermore, non-compliance is often a result of cash flow challenges, in which case the penalties become an unavoidable cost of doing business. A lack of skills and basic tax knowledge lead to unintentional non-compliance; therefore, the penalties must be accompanied by training, awareness and education.
 
Originality/Value: There are conflicting results on the influence of penalties on tax compliance behaviour in the literature. This study contributes to the body of knowledge by adding a South African small business perspective. Furthermore, the qualitative approach applied in this study adds to the body of knowledge and provides original contextual descriptions of the lived experiences regarding the influence of penalties on the tax compliance phenomenon.
Review of the reasons for and effectiveness of switching biologics for psoriasis treatment in Korea
Authors: Shin Jun-Oh , Shin Bong Seok , Bae Kyung-Nam , Shin Kihyuk , Kim Hoon-Soo , Ko Hyun-Chang , Kim Moon-Bum , Kim Byungsoo
Published: May 2023

Background

Switching of biologics in patients has become common in clinical practice.

Objectives

This study investigated the reasons for and effectiveness of switching biologic agents during the treatment of psoriasis.

Methods

We retrospectively reviewed patients with psoriasis who were treated with biologics at Pusan National University Hospital and Chosun University Hospital from March 2012 to June 2020. We assessed their demographics and treatment characteristics (reasons for switching biologics and efficacy of the first- and second biologic agents).

Results

Of the 162 psoriatic patients treated with biologic agents for more than 52 weeks, 35 required a switch to another biologic agent. The reasons for switching biologic agents were inefficacy (n = 30), adverse events (n = 2) and others (n = 3). The mean psoriasis area and severity index (PASI) score was 12.1 at the start of the second biologic and 3.4 at 14–16 weeks later. Patients were more likely to switch to another biologic agent when they exhibited a high initial psoriasis area and severity index score and concomitant psoriatic arthritis.

Limitations

As a retrospective study, there were some limitations such as lack of a placebo control group and the time point of 14–16 weeks being somewhat early to judge the effect of the biologics.

Conclusions

The most common reason for switching biologic agents in Korea was treatment inefficacy, especially secondary failure. Despite the inefficacy of previous biologic agents, switching to a different agent may be an efficacious approach.
Pustular psoriasis: A distinct aetiopathogenic and clinical entity
Authors: Vasudevan Biju , Das Pankaj , Bhatt Siddharth
Published: May 2023

Pustular psoriasis is a distinct subset of psoriasis that presents with involvement of the skin in the form of sterile pustules along with systemic manifestations. Though it has been conventionally grouped under the umbrella of psoriasis, recent research has shed light on its pathogenetic mechanisms associated with the IL-36 pathway, which is distinct from conventional psoriasis. Pustular psoriasis in itself is a heterogeneous entity consisting of various subtypes, including generalised, localised, acute, and chronic forms. There is confusion regarding its current classification as entities like deficiency of IL-36 antagonist (DITRA) which are closely related to pustular psoriasis both in their pathogenetic mechanism and its clinical manifestations, are not included under pustular psoriasis. Entities like palmoplantar pustulosis, which presents with similar clinical features but is pathogenetically distinct from other forms of pustular psoriasis, are included under this condition. Management of pustular psoriasis depends upon its severity; while some of the localised variants can be managed with topical therapy alone, the generalised variants like Von Zumbusch disease and impetigo herpetiformis may need intensive care unit admission and tailor-made treatment protocols. The advent of newer biologics and better insight into the pathogenesis of pustular psoriasis has opened the way for newer therapies, including tumour necrosis factor-alpha inhibitors, interleukin-1 inhibitors, interleukin-17 inhibitors, and granulocyte monocyte apheresis. It continues to be an enigma whether pustular psoriasis is actually a variant of psoriasis or an entirely different disease entity, though we feel that it is an entirely different disease process.
Nail cosmetics: What a dermatologist should know!
Authors: Tyagi Meha , Singal Archana
Published: May 2023

Nail cosmetics industry is growing at an enormous rate globally due to a surge in nail care all around the world. Various nail cosmetics are available, such as nail polish along with its variants like shellacs, finishes, artificial nails, adornments, and nail polish removers. Nail cosmetics serve aesthetic as well as therapeutic purposes, with the end result being smooth, attractive nails. Nail grooming procedures have evolved from a basic manicure to many other advanced procedures like gel nails, nail tattooing, etc. Although a majority of nail cosmetics are considered safe, they may have potential complications, including allergic and irritant reactions, infections, and mechanical effects. The majority of the procedures related to nail enhancement are not performed by dermatologists but by beauticians with inadequate or no knowledge of the nail’s anatomy and functions. The hygiene at the so-called nail-salons/beauty parlours is not standardised, leading to acute complications like paronychia and nail dystrophy following matrix injury. The use of nail cosmetics has become widespread, making it essential for dermatologists to be aware of the nail care products, aesthetic procedures pertaining to nails, and related adverse effects.

The definition of the genetic/molecular profile of gliomas is currently essential for the classification of the disease, prognosis, choice of treatment, and it is still dependent on surgical biopsies, which in many cases become unfeasible. Liquid biopsy with detection and analysis of biomarkers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) from the tumor and circulating in the bloodstream or cerebrospinal fluid (CSF) has emerged as a minimally invasive alternative to aid in diagnosis, follow-up, and response to treatment of gliomas.

Methods:

Through a systematic search in the PubMed MEDLINE, Cochrane Library, and Embase databases, we reviewed the evidence on the use of liquid biopsy to detect tumor DNA/RNA in the CSF of patients diagnosed with central nervous system gliomas.

Results:

After a systematic review applying all inclusion and exclusion criteria, as well as a double review by independent authors, 14 studies specifically addressing the detection of tumor DNA/RNA in the CSF of patients diagnosed with central nervous system glioma were selected in the final analysis.

Conclusion:

Sensitivity and specificity of liquid biopsy in CSF are still very variable depending on factors such as the diagnostic method, collection timing, biomarker (DNA and RNA), tumor type, extension and volume of the tumor, collection method, and contiguity from neoplasm to CSF. Despite the technical limitations that still exist and prevent the routine and validated use of liquid biopsy in CSF, the growing number of studies around the world is increasingly improving this technic, resulting in promising prospects for its use in diagnosis, evolutionary follow-up, and response to the treatment of complex diseases such as central nervous system gliomas.

Thanks to the high compression of the matrix product state (MPS) form of the wave function and the efficient site-by-site iterative sweeping optimization algorithm, den- sity matrix normalization group (DMRG) and its time-dependent variant (TD-DMRG) have been established as powerful computational tools in accurately simulating the elec- tronic structure and quantum dynamics of strongly correlated molecules with a large number (10 1−2 ) of quantum degrees of freedom (active orbitals or vibrational modes). However, the quantitative characterization of the quantum many-body behaviors of realistic strongly correlated systems requires a further consideration of the interaction between the embedded active subsystem and the remaining correlated environment, e.g., a larger number (10 2−3 ) of external orbitals in electronic structure, or infinite condensed-phase phononic modes in nucleus dynamics. To this end, we introduced three new post-DMRG and TD-DMRG approaches, namely (1) DMRG2sCI-MRCI and DMRG2sCI-ENPT by the reconstruction of selected configuration interaction (sCI) type of compact reference function from DMRG coefficients and the use of externally contracted MRCI (multi-reference configuration interaction) and Epstein-Nesbet per- turbation theory (ENPT), without recourse to the expensive high order n-electron reduced density matrices (n-RDMs). (2) DMRG combined with RR-MRCI (renormal- ized residue-based MRCI) which improves the computational accuracy and efficiency of internally contracted (ic) MRCI by renormalizing the contracted bases with small-sized buffer environment(s) of few external orbitals as probes based on quantum informa- tion theory. (3) HM (hierarchical mapping)-TD-DMRG in which a large environment is reduced to a small number of renormalized environmental modes (which accounts for the most vital system-environment interactions) through stepwise mapping trans- formation. These advances extend the efficacy of highly accurate DMRG/TD-DMRG computations to the quantitative characterization of the electronic structure and quan- tum dynamics in realistic strongly correlated systems coupled with large environments, and are reviewed in this paper.

Polyacrylamide (PAM) hydrogels are extensively used as extracellular matrix mimics to study specific cell-materials interactions. However, chemistries typically applied for biofunctionalization of PAM lack chemo-selectivity and control over ligand density, which undermine reproducibility of cellular behavior, which can lead to inconclusive experiments. In this work, we introduce firefly luciferin-inspired click ligation to enable controlled and tunable biofunctionalization of PAM hydrogels. A novel acrylamide-based co-monomer is synthesized and incorporated in PAM hydrogels using traditional protocols, which introduces cyanobenzothiazole (CBT) functional groups. CBT mediates biofunctionalization of PAM with N-Cys bearing biomolecules via luciferin click chemistry. Biofunctionalization takes place under mild conditions, with high efficiency within only a few minutes, and does not require light exposure. When compared to the current commercial gold standard for PAM biofunctionalization sulfo-SANPAH, hydrogels modified via luciferin click ligation show increased control in loading of cell-adhesive biochemical cues. This leads to increased cellular attachment, spreading and proliferation due to a more efficient, homogeneous, and functional biofunctionalization. Luciferin-inspired click ligation may become a new standard for reliable biofunctionalization of PAM hydrogels with increased control over the density and preserved function of the presented biological cues, thus allowing more robust platforms for 2D cell-materials interaction experimentation.

Published: May 2023

Objective: With ageing, physical attractiveness decreases, and weight gain and wrinkles increase, which leads to an increase in the tendency towards plastic surgery. However, the level of religious attitude can influence this tendency. This study was conducted to determine the effect of the religious commitment level of women over 40 years on their perspectives on cosmetic surgery.
Materials and Methods: This descriptive and cross-sectional study was conducted with 452 women aged 40-65 who visited a hospital's outpatient clinic in Türkiye..
Results: It was determined that 61.5% of the women who participated in the study had a high religious commitment. The women with high levels of religious commitment were found to have a lower desire for cosmetic surgery (p<0.001).
Conclusion: The cosmetic surgery perspective was found to be adversely affected by the frequency of devotion and worship practices.

Objective: The aim of this study is to reveal the morphological and morphometric features of the acetabulum and to compare them with the current literature.
Materials and Methods: A total of 57 coxae (29 left, 28 right) were examined. The anterior ridge of the acetabulum was classified as curved, straight, angular, and irregular according to its morphological features and the transverse diameter of the acetabulum (TD), the vertical diameter of the acetabulum (VD), the anteroposterior diameter of the acetabulum (APD), acetabular depth (AD), acetabular notch width (ANW) and os coxae height (CH) were measured.
Results: The types of the anterior ridge of the acetabulum were found as 19 (33.3%) straight, 18 (31.6%) curved, 14 (24.6%) angular, and 6 (10.5%) irregular in shape. The mean values of the TD, VD, APD, ANW, AD and CH were 50.67±3.12 mm, 52.21±3.52 mm, 52.66±3.73 mm, 22.64±2.67 mm, 29.75±2.28 mm and 206.33±11.70 mm respectively. No significant difference was found between the right and left coxae in terms of the measured parameters (p>0.05). There was only a difference between the shapes and the depth of the acetabulum (p<0.05).
Conclusion: Knowing the normal anatomy of the acetabulum is important in preventing complications during surgical procedures of this area.

Published: May 2023

Objective: The study aimed to assess the sternum's morphology and morphometry, and to find anomalies and diseases using breast magnetic resonance imaging (MRI).

Materials and Methods: Retrospective evaluations of 320 breast MRIs were conducted. Congenital abnormalities accompanying pathological conditions were investigated. The sternum overall’s length, the manubrium-corpus’ width and length, and the manubrium-corpus-xiphoid’s shape were all measured. The relationship between the manubriosternal fusion and age was analyzed.

Results: Pectus excavatum, sternal band, sternal foramen, angled sternum and the sternal band, rachitic rosary, intraosseous ganglion, sternoclavicular joint degeneration, sternoclavicular joint ganglion cyst and costal cartilage calcifications, breast carcinoma metastasis, enchondroma and invasion of costal cartilages by malignant mesenchymal tumour were determined. The average length of the sternum was 144±14 mm, the manubrium length is 46±6 mm and the corpus length is 89±10 mm for adults. Manubrium was most commonly trapezoid in shape, the corpus was longitudinal oval and xiphoid was flat. 67% had no manubriosternal fusion. The degree of manubriosternal fusion did not show statistically significant correlation with increasing age.

Conclusion: The sternum, sternoclavicular, and sternocostal joints are susceptible to a wide range of congenital abnormalities and clinical conditions. Age increase has no relation to manubriosternal fusion.
