MEASURING TECHNOLOGICAL CAPABILITY AND BUSINESS PERFORMANCE POST-COVID ERA: EVIDENCE FROM SMALL AND MEDIUM-SIZED ENTERPRISES(SMEs) IN NIGERIA
Authors:   National Open University of Nigeria, Olubiyi Timilehin Olasoji
Published: November 2022

The coronavirus pandemic has resulted in a significant shock to businesses, with negative implications on present production capacity. Simultaneously, technology is being increasingly recommended as a significant means of minimising economic losses caused by the pandemic. Survival and lack of performance of small and medium-sized businesses continue to generate public discourse, intellectual interest, and attention. Though relationship between technological capabilities and business performance is more intricate than is often assumed. Inadequate technological capability is one of the primary factors contributing to business situation. Therefore, relationship between technological capability (TC) and business performance was examined amongst selected small and medium-sized businesses in Lagos State. This study used a survey research methodology with a sample size of 742 owner-managers of chosen SMEs in Lagos State. A questionnaire that was adopted and validated for the study was used to collect data. The questionnaire questions' Cronbach's alpha coefficients range from 0.77 to 0.88. The response rate to the survey was 94.5 percent. Using descriptive and inferential statistics, the acquired data was analysed (Pearson product moment correlation and regression analysis). The examination of the data demonstrated a significant association between technological capacity and small company performance (= 0.090, t = 3.029, F= 245.45 p.05). The conclusion of this research is that technical aptitude is a resource that enhances the performance of small businesses, with theoretical and practical consequences for businesses. It is recommended that the managers of small and medium-sized enterprises (SMEs) in Lagos State use their technology capability as a business resource, since this could help them generate new ideas or enhance existing goods.

Published: November 2022

Objective

The present study aimed at measuring the level of public speaking anxiety (PSA) among medical residents in Riyadh, in addition to identifying the factors influencing public speaking anxiety from the perspective of the medical residents.

Method

A cross-sectional survey was conducted over a sample of 203 medical residents in Riyadh. The study adopted the questionnaire as a data collection tool. The questionnaire consisted of a demographic data part, PSA scale (17 items) and a third part concerned with the factors influencing public speaking anxiety among medical residents.

Results

The results of the study revealed that medical residents in Riyadh had a low level of public speaking anxiety (47.3±11.32). The participants had a low PSA score on all scale domain; cognitive (23.28±5.43), behavioral (10.45±4.16), and physiological (13.54±3.44). Moreover, the findings of the study showed that stuttering (91.1%), negative perceptions of individuals’ own voice (77.8%), and language barriers (76.8%) were the main factors influencing the public speaking anxiety among medical residents. Finally, we found through linear regression analysis that PSA is not significantly predicted by participants’ living region, marital Status, gender, residency level, type of pre-college school, age or being previously diagnosed by a mental health issue.

Conclusion

There is a low level of public speaking anxiety among medical residents in Riyadh. In addition, the study concluded that stuttering, negative perceptions about voice and language barriers are negatively influencing the public speaking anxiety among medical residents in Riyadh.

Published: November 2022

Authorship of peer-reviewed publications is important for academic rank, promotion, and national reputation. In pain medicine, limited information is available for authorship trends for women as compared with men. The objective of this study was to describe trends of female authorship data in the 5 pain journals with the highest impact factors over a 10-year period. We analyzed data for January, April, and October in 2009, 2014, and 2019. For each article, the following information was recorded: journal name, journal month, journal year, article title or article PMCID, total authors, total female authors, total male authors, total authors of unknown gender, presence or absence of a female first author, and presence or absence of a female last/senior author. Authorship for 924 articles was reviewed. When a man was senior author, women were first author on only 27.9% of articles (P<.001). A woman was 2 times as likely (57.2%) to be first author when a woman was the senior author (P<.001), pointing to the potential impact of female senior authors. An article with 50% or more female authors was 76.4% more likely to have a female senior author (P<.001). The results demonstrate the influence of a senior female author on the likelihood of an article’s having a female first author. When men were the senior authors, women were half as likely to be first authors. The total number of female authors changed very little between 2009 and 2019.

Case

Clavicle fractures are common skeletal injuries that account for 2%-10% of adult fractures. Surgical indications include presence of an open fracture, severe angulation, comminution, displacement, skin tenting with a threat of skin perforation, neurovascular compromise, symptomatic nonunion, or fracture shortening >1.5-2cm. In this case, the patient had a comminuted, displaced fracture - thus meeting criteria for operative treatment. However, the patient opted for nonoperative management.

Conclusion

After 3 months, the patient regained full strength and range-of-motion. This case highlights the current heterogenous mixture of studies in the literature surrounding the best management for midshaft clavicle fractures.

The patient was informed that data concerning the case would be submitted for publication and provided consent.

Major Depressive Disorder (MDD) is a major cause of disability worldwide and is associated with serious lasting impairment. A leading hypothesis of the pathophysiology of MDD is the monoamine deficiency hypothesis which suggests that depression is caused by depletion of serotonin, norepinephrine, or dopamine in the central nervous system. Serotonin is the most widely studied neurotransmitter in the pathophysiology of depression, with studies showing that reduced central serotonin synthesis leads to depressive symptoms in individuals at risk for depression. Selective Serotonin Reuptake Inhibitors (SSRI) inhibit serotonin reuptake and subsequently increase the amount of serotonin available in synapses. Common side effects of SSRIs include increased suicidality of patients under the age of 25, sexual dysfunction, anxiety, dizziness, weight gain, gastrointestinal distress, and headache. Other side effects include prolonging the QT interval, coagulopathy, and the risk of serotonin syndrome, as well as SSRI discontinuation syndrome. Sites of increased bleeding related to SSRI use have been reported to occur in the upper gastrointestinal tract, as well as intracranially. Based on the current literature, three studies have found that SSRIs are not associated with increased bleeding and/or increased perioperative risk, while others have demonstrated that SSRIs are associated with an increased risk in perioperative use. The inhibition of serotonin reuptake can affect platelet aggregation since platelets also express the serotonin transporter. SSRIs can result in decreased storage of serotonin in platelet dense granules. Increased serotonin can also increase gastric acid secretion, which increases the risk for ulceration. SSRIs in combination with NSAIDs also show a significantly increased risk of upper GI bleeding. Some studies show an increased bleeding risk from 30% to 70% when taking a combination of vitamin K antagonists and SSRIs in hospitalized patients. Related to the high prevalence of conditions that are treated with SSRIs, the bleeding risk associated with this class of medication merits further study.

Frameless cinema: Proposed scale of narrative involvement in virtual reality
Authors: Bonilla Diego , Fajardo Helena Galán
Published: November 2022

The possibility of recording in 360° has aroused the interest of entrepreneurs and researchers in the potential narrative powers of virtual reality in different fields. However, there are still some questions that have not been sufficiently confirmed, such as the higher level of narrative involvement of the viewer in this new form of storytelling. In order to make up for this lack, this research presents the design of an experimental analysis in different phases. It is a quantitative-qualitative pilot project based on the MNEQ scale[1] that allows us to evaluate and compare the viewing experience of a narrative story through virtual reality presentation and different types of two-dimensional screens to a minimum of 100 people divided into experimental groups. Under the assumption that each treatment or each technology (independent variable) has different impacts on the viewer’s narrative involvement (dependent variable), the aim is to analyze empathy (EP), sympathy (S), cognitive perspective taking (CP), loss of time (LT), loss of self-awareness (LS), narrative presence (NP), narrative involvement (NI), distraction (D), ease of cognitive access (EC) and narrative realism (NR). Four different types of analysis (statistical, variance, observational, open-ended) are included. We offer a new model of self-developed analysis for complete Spanish-language cinematic virtual reality works. The experimental design seeks to establish a comprehensive research model in order to discuss whether virtual reality offers, as it is believed, greater engagement.

The artistic generation of the meta universe: Tracing the source of NFT art
Authors: Guo Chunning
Published: November 2022

NFT has become a hot topic in the art circle recently, and encryption art has also stepped on a new stage with the support of new technologies and systems such as blockchain from 2019 to 2020, NFT art showed explosive growth. Many representative cases updated the traditional definition of art source, copyright and media, and also triggered the participation and interaction of a wider audience. The author believes that this new cultural and artistic phenomenon needs to be observed from a more in-depth and comparative perspective. In a broader sense, NFT art has formed a profound intertextual relationship with the concept of “meta universe” constructed from Science Fiction Texts into reality in recent ten years. Through the discussion of digital identity, fair trade and gameplay, this paper regards NFT art as a meta universe pointing to the future, and discusses the generation and evolution of NFT as a digital mechanism from the revolution of the art world.
Metaverse as a cross complex scene of technical education
Authors: Mujica-Sequera Ruth M.
Published: November 2022

In the digital age, major changes have taken place in the field of education. All those involved in the teaching stage are invited to reflect on the challenges involved in technical literacy. The purpose of this article is to consider the cross-complexity challenges involved in technical literacy as metaverse enters the classroom. With the support of humanistic paradigm, literature research adopts philological methods, qualitative methods, exploratory interpretation types, literature design, reading technology and search tools, organization and information analysis. After two years in prison, the educational process is still utopian in the face of a technological world full of differences, prototypes, contradictions and challenges. Before existing bases are subject to the wrong dogma that technology will replace them or become their biggest enemy, the education system must be strengthened to understand the changes of prototypes. Surprisingly, the pandemic has fostered a vision of a world where it is possible to assess, reassess and give new relevance to the training process. Therefore, it is necessary to balance the beliefs of epistemology, ontology, teleology, axiology and methodology, and produce a new dialogue in the interrelated educational practice. In this dialogue, transcendence is promoted and a higher level of knowledge is achieved under the internal reflection of people in digital education.

Changes in technology and civilization—A conceptual study of the Metaverse
Authors: Fang Lingzhi , Shen Huangnan
Published: November 2022

Advances in media technology continue to drive changes in the shape of human society, and human civilization has stepped into the eve of the Metaverse. Based on this practical background, this paper analyzes the Metaverse concept from three aspects: the proposed background, construction and characteristics of the Metaverse, and analyzes and summarizes the impact of the Metaverse on the current situation of the industry and the future of the industry. This paper argues that the proposal of Metaverse is the inevitable development of society and technology, and the endgame of Internet development. The Metaverse is a product of the constant innovation of the medium and has evolved from the possible worlds in literature to video games. This paper summarizes the basis of Metaverse construction from the perspective of humanities and technologies, and proposes that the Metaverse will develop a virtual civilization in terms of humanities, and be supported by both software and hardware technologies in terms of technologies. On the basis of this foundation, it is extracted that the Metaverse has two characteristics: civilization and intersectionality. This paper summarizes the influence of Metaverse on industry, mainly including the influence of Metaverse on the current layout of industry and the influence on the future development of industry. The concept and impact of Metaverse and its commercial application in industrial development proposed in this paper lay the corresponding theoretical foundation for the subsequent research on Metaverse.

The economics of the metaverse: A comparison with the real economy
Authors: Chen Yongwei , Cheng Hua
Published: November 2022

The economic system is an important component of the metaverse as a virtual world. At the macro level, the metaverse economy operates in three cycles: the inner cycle, the outer cycle, and the virtual-real cycle between the real world and the metaverse. At the micro level, the user is the most important subject of economic activity, acting both as a demander and as a producer of user generated content (UGC). In the metaverse, market demand is based on the use value and scarcity of goods, and market supply is driven by a combination of economic and non-economic motives. The smooth functioning of the metaverse economy relies on property rights and monetary systems, and blockchain technology is increasingly becoming the basis for both of these systems.
New development trends of “metaverse + psychology” blending virtual and reality
Authors: Liu Shen , Bai Jiangzhu
Published: November 2022

Metaverse is a hot topic recently, which has aroused widespread concern from all walks of life. The possible impact of the metaverse on the field of psychology includes creating a new field of panoramic learning process by creating an educational metaverse, creating a more scientific and novel teaching model by creating a MOOC metaverse, breaking the “magic circle” to alleviate interpersonal avoidance and promote individual social behavior, fostering individual self-identity by shaping the metaverse cyberpunk culture, improving the effectiveness of school mental health education by building a metaverse psychological experience center, creating a metaverse psychological intervention system based on traditional behavioral therapy to improve the effectiveness of psychological counseling, etc. However, the emerging technology represented by the metaverse is a double-edged sword. It is not only necessary to pay attention to this opportunity to create a perfect world or to create miracles, but also to guard against potential harm to the development of human society.
Metaverse: Homogenization experience and cultural illusion
Authors: Jiang Jianguo
Published: November 2022

Although the metaverse may bring technological and consumer revolution, from the perspective of cultural model, the metaverse does not lead to significant changes in social emotional structure. The metaverse is still a new form of network technology development. It strengthens visual experience and weakens tactile, taste and auditory experience from this perspective, the biggest feature of the metaverse is the violence of visual culture, which makes the “light rhyme” disappear and makes people form a homogeneous experience in the simulated world. Therefore, we should not superstitious and blindly follow the “meta cosmic culture”.
Rule of the Metaverse
Authors: Zhang Qinyu
Published: November 2022

The moral, economic, security and other social Anomies in the Metaverse need to be corrected, and the social control of the Metaverse is on the line. The rule structure of the Metaverse should embody the concept of multiple co governance, including internal control rules and external control rules Internal control rules occupy a dominant position in the Metaverse. When failure occurs, special intervention of external control rules is required. Dispelling the ethical difficulties brought by the Metaverse and maintaining the good and orderly meta cosmic space order depend on the ethical rules and autonomous rules of the Metaverse. External control rules need to be constructed from three levels: The internal visual threshold of the Metaverse, the comparison and interaction between the Metaverse and the real world, and the interconnection between the Metaverses. The Metaverse makes it possible to reshape the rules of social equality. The connection rules between the Metaverse and the real world can promote the coordinated development of the Metaverse and the real world. Breaking the barriers between Metaverses can establish an interconnection mechanism between different Metaverses.
Multi-task super resolution method for vector field critical points enhancement
Authors: Yang Yilun , Hao Zhou , Peng Weilong , Tang Keke , Fang Meie
Published: November 2022

It is a challenging task to handle the vector field visualization at local critical points. Generally, topological based methods firstly divide critical regions into different categories, and then process the different types of critical regions to improve the effect, which pipeline is complex. In the paper, a learning based multi-task super resolution (SR) method is proposed to improve the refinement of vector field, and enhance the visualization effect, especially at the critical region. In detail, the multi-task model consists of two important designs on task branches: one task is to simulate the interpolation of discrete vector fields based on an improved super-resolution network; and the other is a classification task to identify the types of critical vector fields. It is an efficient end-to-end architecture for both training and inferencing stages, which simplifies the pipeline of critical vector field visualization and improves the visualization effect. In experiment, we compare our method with both traditional interpolation and pure SR network on both simulation data and real data, and the reported results indicate our method lower the error and improve PSNR significantly.

In the hilly Balkans, a folk proverb has been circulating for a long time, „It is most difficult to be a prophet in one‘s own village“, which reflects the age-old mistrust of the population towards new ideas. This is not surprising in the least, because since the written history of the peoples of the Balkans has existed, a continuous series of conquerors and local rulers who subjugated the common folks and imposed their world view can be traced. Nevertheless, from time to time, people with great strength appear who not only break the shackles imposed by the powerful, but through their actions find a way to the souls of their compatriots and gain their unreserved trust. One of such spontaneous creators is professor Izet Mašić, who achieved a miracle of medical publishing in his Sarajevo and Bosnia and Herzegovina and traced the path of medical science. There may be thousands of medical journals in the world, more or less reputable, and researchers from the Balkans can publish their work in them, but only domestic medical journals can initiate and direct domestic medical research, and educate young researchers in the right way. Professor Mašić made it possible for authors from Bosnia and Herzegovina and other Balkan countries to present their results to the world and receive an incentive from impartial experts to continue their work and progress more and more by editing and publishing three domestic journals at once, which are visible in the most important world bases,. The progress in research then translated into improving medical practice and health care of the population. The following details from Professor Mašić‘s biography tell us how this miracle happened. This year, academician Izet Mašić, Editor-in-Chief of a few biomedical journals, including Acta Informatica Medica journal, celebrates his 70th birthday and also 45 years of his academic and scientific work.

An experiment was conducted to study chlorpyrifos chronic toxicity in broilers and the protective effect of vitamin C. Oral administration of 0.8 mg/kg body weight (bw) (1/50 LD50) chlorpyrifos (Radar�), produced mild diarrhea and gross lesions comprised of paleness, flaccid consistency and slightly enlargement of liver. Histopathologically, chlorpyrifos produced degenerative changes in various organs. Oral administration of 100 mg/kg bw vitamin C partially ameliorated the degenerative changes in kidney and heart. There was insignificant alteration in biochemical and haematological profiles. It is concluded that supplementation of vitamin C reduced the severity of lesions induced by chronic chlorpyrifos toxicity in broilers.

This study screened the antidiarrhoeal, antimicrobial and cytotoxic effects of ethanol-extracted leaves of yellow oleander (Thevetia peruviana). The extract was tested against castor oil-induced diarrhoea in a model of albino rats and showed significant antidiarrhoeal activity (P<0.01). Disc diffusion technique was used to test the in vitro antibacterial activities of the extract and exhibited poor antibacterial activities against both Gram positive and Gram negative bacteria (mainly Bacillus sp). Ethanol-extracted leaves of yellow oleander showed narrow zone of inhibition in the bacterial lawns of Shigella flexineri, Salmonella typhi, Klebsiella sp, Staphylococcus aureus and Shigella sonnei. Cytotoxicty was determined against brine shrimp nauplii and LC50 of the plant extract was determined as 627.21�g/ml. The wide range of LC50 value denotes the safety effect of the extract.
Raw cow’s milk relatively inhibits quorum sensing activity of Cromobacterium violaceum in comparison to raw she-camel’s milk

Milk from different animal species has variable levels of antimicrobial factors against some of spoilage bacteria. For example, they are significantly present in higher concentration in she-camel’s milk than in cattle or buffalo and they are more heat-resistant than their counterparts in cattle and buffalo. Spoilage bacteria are known to communicate with each other by release of signaling molecules, a phenomenon described as quorum sensing (QS). Some food matrices inhibit these signaling compounds. In this study we screened QS inhibitory activities in raw milk of cattle and camel. Ten samples each of fresh raw cow’s milk and she-camel’s milk from apparently healthy animals were screened using the bacterial model Cromobacterium violaceum. The tested cow’s raw milk samples were able to inhibit the production of QS signalling molecules acyl-homoserine lactones (AHLs) produced by C. violaceum. However, she-camel’s milk samples were less effective in inhibiting such AHLs. Thus, one of the factors which influence the inhibitory activity could be derived from variation in milk chemical composition, especially in the percentage of fat which is significantly higher in tested cow’s milk samples (2.22±0.12) than in tested she-camel’s milk samples (1.44±0.35). Natural inhibition of QS signaling by cow’s milk may offer a unique means to control foodborne pathogens and reduce microbial spoilage.
Antibiogram and heavy metal tolerance of bullfrog bacteria in Malaysia
Authors: Najiah L
Published: November 2022

Bacterial isolates from 30 farmed bullfrogs (Lithobates catesbeianus) weighing 500-600 g at Johore, Malaysia with external clinical signs of ulcer, red leg and torticollis were tested for their antibiograms and heavy metal tolerance patterns. A total of 17 bacterial species with 77 strains were successfully isolated and assigned to 21 antibiotics and 4 types of heavy metal (Hg2+, Cr6+, Cd2+, Cu2+). Results revealed that bacteria were resistant against lincomycin (92%), oleandomycin (72.7%) and furazolidone (71.4%) while being susceptible to chloramphenicol and florfenicol at 97.4%. The multiple antibiotic resistance (MAR) index for C. freundii, E. coli and M. morganii was high with the value up to 0.71. Bacterial strains were found to exhibit 100 % resistance to chromium and mercury. High correlation of resistance against both antibiotics and heavy metals was found (71.4 to 100%) between bullfrog bacteria isolates, except bacteria that were resistant to kanamycin showed only 25% resistance against Cu2+. Based on the results in this study, bacterial pathogens of bullfrog culture in Johore, Malaysia, were highly resistant to both antibiotics and heavy metals.
A case of non-regenerative immune-mediated anemia treated by combination therapy of human immune globulin and mycophenolate mofetil in a dog
Authors: Yuki M
Published: November 2022

A 12-year-old female Shih Tzu dog was referred with diarrhea. Hematological examination indicated severe non-regenerative anemia. Bone marrow aspiration smears and core biopsy specimens revealed normal bone marrow. Based on those results, non-regenerative immune-mediated anemia was diagnosed. The dog was initially treated using prednisolone and cyclosporine. However, this treatment regimen did not prove effective. Nevertheless, the patient achieved a good hematological response after the administration of a combination therapy of human immune globulin and mycophenolate mofetil. Such a combination therapy may prove effective against non-regenerative immune-mediated anemia.

Published: November 2022

A 7-year-old Labrador Retriever female dog presenting left forelimb lameness for one day was admitted to the Veterinary Hospital (UNESP-Botucatu) for clinical evaluation. Several tests, including blood and image analysis, microbiological culture and cytology of lytic areas of affected bone were made in order to establish a diagnosis. Serum biochemical profile revealed increased levels of liver enzymes, plasma globulin, creatine kinase (CK) and calcium. Hemogram revealed anemia and leukocytosis; left humerus image analysis revealed an osteolytic lesion and cytology revealed a suppurative periostitis. Differential diagnosis was a nonspecific infectious inflammatory process or osteosarcoma. Since it was not possible to achieve a definitive diagnosis and there was a highly suspicious for an infectious agent, an agarose cell block of the bone marrow fine-needle aspiration was made. The cytological examination of cell block presented similar findings as described previously. However, additional stains including periodic acid-Schiff (PAS) were positive for fungal hyphae, which rendered a diagnosis of fungal osteomyelitis due to Aspergillus spp. This case report illustrates an uncommon cause of osteomyelitis for breed that was diagnosed by an underused method in veterinary medicine.

Watercress (Nasturtium nasturtium) is a medical plant containing diverse chemically-active substances with biological properties. The present study was conducted to investigate the immunomodulatory effects of watercress extract on immunological and hematological parameters of rainbow trout (Oncorhynchus mykiss). Fish were fed for 21 days with diet supplemented with 0.1% and 1% of watercress extract per 1 kg food and with a normal diet as control. Hematological parameters such as red blood cells (RBC) and white blood cells (WBC), hematocrit (Hct), hemoglobin (Hb), RBC index like mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) as well as immunological parameters such as peroxidase, lysozyme and complement activities, total protein, albumin and globulin levels were measured after 21 days of watercress extract treatment. The results indicated that oral administration of 1 % watercress extract in fish may enhance some hematological and immunological parameters including Hb and MCHC, lysozyme and complement activities, total protein and globulin levels, compared to the controls after 21 days of experimental period. In conclusion, on the basis of these results, oral administration of watercress extract may be useful to improve fish’s immune system.
