A CRITICAL EVALUATION OF SMES ATTITUDES TOWARDS INFORMATION TECHNOLOGY INTEGRATION IN NIGERIA
Authors: Ihesiene Ugwu Chukwuemeka , Akpojaro Jackson
Published: October 2021

Globally, there is a growing trend towards high dependence on knowledge, information, IT skills and application of these resources within business environments. It is alarming that many small and medium scale enterprises (SMEs) in Nigeria are either unwilling or slow at integrating effective IT innovations and practices as indicated by reduced rate of IT expert engagements, trendy preference for hiring computer biased non-professionals to drive IT function as well as infusion of IT units into other departments. This paper therefore discusses these attitudes of SMEs towards IT as bases for recommending remedial approaches to the phenomenon. While the research questions addressed the extent to which inadequate financing, competence, limited knowledge, management perception, nature of business and resistance to change constitute major factors contributing to these attitudes, it posits that trend reversal can be achieved through competitive IT education, adaptive IT framework for SMEs, establishment of IT office as a statutory requirement for SMEs, adequate funding, etc. The study employs a descriptive research design using 100 randomly selected registered SMEs across all sectors of the Nigerian economy. Simple percentages, mean distribution and Chi-Square were used in the statistical analysis to predict factors influencing the undesirable SMEs’ attitudes towards IT. The research results identify management perception as the greatest factor contributing to SMEs’ attitudes. Therefore, this paper is relevant and of interest to all who have a stake in Nigeria’s emerging knowledge based economy.
INFLUENCE OF LIFESTYLE ON THE BUYING BEHAVIOUR OF UNDERGRADUATE STUDENTS IN UNIVERSITIES IN CROSS RIVER STATE, NIGERIA
Authors: Udo-Imeh Philip Thomas
Published: October 2021

The undergraduate students in universities in Nigeria are a major and growing market for providers of consumer goods and services in the towns and cities where universities are located. The few empirical studies that have been conducted on this population were focused on the demographic and cultural dimensions whose limitations at explaining and predicting consumer behaviour have been acknowledged by many scholars and researchers. Those studies also did not consider the moderating effect of socio-demographic factors which have been shown to improve the predictability of consumer behavior. This study, therefore, aimed at assessing the relationship between lifestyle and buying behavior among undergraduate students in universities in Cross River State, Nigeria. Lifestyle was measured on the activities, interests and opinion framework. A sample of 323 undergraduate students was drawn from the two universities in Cross River State, using a three-stage sampling technique. Multiple regression analysis was used in testing the hypotheses. The study shows that lifestyle significantly influence buying behaviour of undergraduate students in universities in Cross River State, with interest making the greatest contribution on the impact of lifestyle on buying behaviour. The study also reveals that socio-demographic variables have significant moderating effect on the influence of lifestyle on buying behaviour with interest making the greatest contribution to buying behaviour and gender making the least contribution. The study concluded that lifestyle is a significant predictor of buying behaviour of undergraduate students in Nigeria. It was recommended that universities students should be segmented on the dimension of lifestyle. The study further recommended that marketers and businesses should factor lifestyle in the development of new products and designing of marketing communication strategies.

Authors: N.W. Confidence , D.E. Isaac , I.W. Anthony
Published: October 2021

The maternal mortality ratio (MMR) for Nigeria is 512 deaths per 100,000 live births, suggesting one of the highest in the world. Furthermore, disparities still exist between northern and southern Nigeria, and across the states of the country with varying contributing factors. This study therefore aimed to identify the predictors of maternal mortality in Rivers State, Southern Nigeria using the technique of logistic regression. Diagnostic study design was utilized for the study and data for women of childbearing age (15–49 years) were extracted from the Rivers State Hospital Management Board, Port Harcourt from January to December 2019. The association between the maternal mortality and selected maternal and health care related factors were tested using chi-square, and multivariate logistic regression was used to identify the effects of maternal and health care related factors on maternal mortality at 5% level of significance. The study identified maternal age, educational level, place of residence, marital status, delivery outcome, baby weight, ANC attendance and parity as the risk factors of maternal mortality in Rivers State. With the risks factors identified, policy makers will be better informed to plan intervention programmes to reduce maternal mortality in Rivers State and fast track the achievement of SDG goals on maternal health.

Authors: Самашев Зайнолла , Жунисханов Айдын Сенгалиевич
Published: October 2021

Сяньби – полиэтническая общность, возникшая в начале І тыс. н.э. в пространствах Центральной Азии. Продвижение сяньбийцев на запад совпало с распадом империи хуннов в ІІІ в. н.э. Начиная с этого периода сяньбийцы стали расселяться на территории Восточного Казахстана и устанавливать свое политическое господство. Изучение археологических памятников сяньбийцев проводится систематично с 2016 г. За это время исследовано свыше 60 выкладок. Проблемы расселения и миграции сяньбийцев на территории современного Восточного Казахстана расмастривались в основном в рамках сравнительно-типологического анализа. В связи с этим огромное значение имеет получение и оперативное введение в научный оборот радиоуглеродных калиброванных дат, связанных с сяньбийским периодом. В данной статье впервые в научный оборот вводятся результаты радиоуглеродного анализа, полученного из остеологического материала присходящего из выкладки № 68 могильника Берел и впускного погребения царского кургана могильника Елекесазы. Радиоуглеродный анализ был выполнен в Государственном научно-исследовательском институте Центра физических и технологических наук г. Вильнюс (Литва) (ответственный за исследование Жилвинас Ежеринскис). В результате были получены новые данные о расселении сяньбийцев на территории Восточного Казахстана.

Authors: Moraes Gustavo Simão , Pinto Shelon Cristina Souza , Campagnoli Eduardo Bauml
Published: October 2021

Este trabalho teve como objetivo verificar a presença de contaminação microbiana em luvas de procedimentos nãoestéreis no momento da abertura de suas caixas e após dois dias nos quais as mesmas ficaram armazenadas e disponíveis para o uso de professores, funcionários e alunos nas clínicas de Odontologia de uma Universidade da região sul do Brasil. O conteúdo coletado da superfície das luvas foi semeado em meios de cultura sólidos, os quais permaneceram cinco dias em estufa a 37°C. Após esse período, as unidades formadoras de colônias (UFC) foram quantificadas, avaliadas quanto à morfologia, e submetidas ao teste da catalase e coloração de Gram, sendo as lâminas obtidas analisadas em microscopia de luz. As placas de Petri ainda foram mantidas por mais três dias fora da estufa, para que microrganismos que têm preferência pela temperatura ambiente pudessem crescer. As UFC que cresceram durante este intervalo foram submetidas às mesmas análises citadas anteriormente. A técnica de microcultivo foi realizada para analisar os fungos filamentosos, e as lâminas obtidas foram coradas com azul de algodão lactofenol e observadas em microscopia de luz. Os dados obtidos foram analisados no software BioEstat 5.0, adotando-se nível de significância de 5%. Houve predomínio de bactérias Gram-negativas, principalmente na forma de bacilos. Foram encontrados fungos filamentosos dos gêneros Aspergillus, Fusarium, Penicillium e Paecilomyces e leveduras Gram-positivas. Concluiu-se que a maior parte das luvas já estava contaminada no momento da abertura das caixas, e a exposição ao ambiente das clínicas de Odontologia aumentou significativamente a contaminação existente.

Crianças com dificuldades de aprendizagem são aquelas portadoras de problemas comportamentais da infância que interferem em suas habilidades acadêmicas. Estudos brasileiros apontam as dificuldades de aprendizagem como a principal causa da busca por tratamento psicológico na rede pública. Frente a esta demanda, no ano de 2006, foi elaborado um programa de intervenção clínica e de educação em saúde, oferecido por uma equipe de Estratégia de Saúde da Família à uma escola pública de ensino fundamental, em cidade de médio porte do interior do estado de São Paulo. Este programa, denominado Remédio para Alma, tem como público-alvo crianças de 6 a 10 anos de idade, cursando do primeiro ao quinto ano letivo, que apresentam dificuldades de aprendizado detectadas pela professora. O presente estudo tem como objetivo conhecer as repercussões da participação no programa na vida dos alunos, segundo a percepção dos envolvidos no contexto educacional do programa. Para tanto, utilizou-se uma abordagem qualitativa, com entrevistas de todos os 18 educadores envolvidos, que foram submetidas à Análise de Conteúdo Temática de Gomes e extraídos sete temas: Acesso ao tratamento; Adesão ao programa; Aproximação dos pais e interação com a escola e com a Equipe de Saúde da Família; Melhora no comportamento; Melhora no conhecimento da história do aluno; Avanço no processo pedagógico; e Repercussão positiva do programa. Concluiu-se que a repercussão do programa na vida do aluno se deu por meio do acesso aos profissionais de saúde e aos tratamentos, que geram supostas melhorias comportamentais, influenciando no desempenho escolar. A aproximação dos pais e sua interação com a Estratégia de Saúde da Família e com a escola também foram apontados como relevantes fatores de repercussão na vida dos alunos participantes do programa. O estudo está dividido em duas partes. Na primeira parte são apresentados os aspectos introdutórios e revisão de literatura do estudo e na segunda parte estão presentes as discussões e conclusões do estudo.

Background: There are shared guidelines about Non-Operative Management (NOM) of splenic injuries, but some unanswered questions remain. The aim of the present study is to establish the usefulness of a standardized protocol for management and follow-up of NOM patients with splenic injuries. Methods: Multicenter retrospective observational study including patients with major blunt trauma (ISS >15) with splenic injuries managed between January 1st 2014 and December 31st 2016 in two Italian I level Trauma Centers: one with a standardized management and follow-up protocol for NOM (Bufalini Hospital, Cesena, BH), and the other without it (ASST Papa Giovanni XXIII Hospital, Bergamo, PG23H). Comparison between patients’ outcomes were performed and a propensity score model was calculated. Results: 47 patients managed in BH and 49 patients in PG23H were included. In BH, a higher proportion of patients was treated with NOM (72.3 % vs. 53.1 %, p = 0.051). There was no difference in complication rate and mortality in patients treated with NOM in the two hospitals. A borderline significant trend to a higher NOM failure rate in PG23H was found (BH 0.0 % vs. PG23H 11.3 %, p = 0.076). The total splenic conservation rate was significantly higher in BH (BH 72.3 % vs. PG23H 46.9 %, p = 0.011). After the Propensity Score based matching, 72 patients were included and the total splenic conservation rate was significantly higher in BH (BH: 77.8 % vs. PG23H: 50.9 %, p = 0.014). Conclusions: The application of a protocol for in-hospital management and follow-up for NOM of patients with splenic injury could decrease the NOM failure rate and improve splenic conservation rate.

Prosthetic treatment of chronic periodontitis often includes making the fixed prosthesis. Its quality links to the simultaneous restoration of lost functions, creation of aesthetics, its mechanical strength and hygienic possibilities. However, sometimes in an attempt to achieve the maximum aesthetic effect and excellent resistance of prostheses, the hygienic possibilities can be ignored. Considering the aetiology of periodontal disease and the influence of local risk factors, we can note that in restoring the integrity of the dental arch, the health of periodontal tissue that often suffers during and due to orthopaedic procedures have to be taken as a priority. The long-term prognosis of a prosthesis, namely of the fixed prosthesis will depend largely on the symbiotic relationship that it will establish with the marginal periodontium.

According to the literature, the most common orofacial pains whose origin are not in the structures of the stomatognathic system, but which are encountered in the offices of dentists are tension pain, trigeminal neuralgia and migraine. Therefore, our main task is to differentiate between facial pain of dental origin, which are in our competence to manage them and other painful orofacial pathologies, which require the cooperation of several specialists. Facial pain, whether muscular or joint origin, has the qualities of a deep somatic pain, always occurs after a recent event (trauma, dental fracture, dental treatment, occlusal changes), is accompanied by disruption of functions (mastication, phonation) and it often causes limited mandibular movements. The presence of muscular, articular, vascular and neurological structures in a restricted anatomical territory often makes difficult to establish the correct diagnosis, that’s why the interdisciplinary approach is inevitable and recommended.

A sensitive, selective and precise liquid chromatographic method has been developed and validated for simultaneous determination of moxonidine and amlodipine besylate both as bulk drug and in formulation. Phenomenex Luna c18 column (250 x 4.6 mm id, 5μm particle size) chromatographic column equilibrated with mobile phase methanol: acetonitrile: 0.02M Kh2PO4 buffer (50:10:40, V/V/V) was used. Mobile phase flow rate was maintained at 1 mL/min and effluents were monitored at 237 nm. The sample was injected using a 20 μL fixed loop, and the total run time was 10 min. The retention times of moxonidine and amlodipine besylate were observed to be 2.9 and 6.9, respectively. The linear regression analysis data for the calibration plots showed a good linear relationship for moxonidine and amlodipine besylate over a concentration range of 0.05-20 μg/mL and 0.05-20 μg/mL, respectively. The method was validated for precision, robustness and recovery. The limit of detection and limit of quantification for moxonidine and amlodipine besylate were found to be 0.0030 μg/mL and 0.0036 μg/mL, 0.015μg/mL and 0.020 μg/mL, respectively. Moxonidine and amlodipine besylate stock solutions were subjected to acid and alkali hydrolysis, chemical oxidation, dry heat degradation and photo degradation. The degraded product peaks were well resolved from the pure drug peak with significant difference in their Rt values. Stressed samples were assayed using developed hPLc method. Statistical analysis showed that the method is repeatable, selective, and precise. Degradation products produced as a result of stress studies did not interfere with the detection of moxonidine and amlodipine besylate and the assay can thus be considered stability-indicating.

There are many challenges facing the service composition process. These challenges include, how to integrate services to satisfy global user requirements, missing or changeable values of QoS, and how to reduce the large solution space of candidate services. In this paper, we proposed a framework to address these challenges. The proposed framework consists of three phases. The Normalizer phase gives a certain range for all QoS attributes and historical user orders. During the Clustering phase, the search space is reduced. Finally, the composition process is done, and a list of candidate composite services is generated through the Service composer phase. We present the hybrid bio-inspiration technique to implement the proposed framework and prove its applicability. In addition, we introduced the MR-FPSO algorithm to implement this phase by merging PSO and FOA optimization algorithms over the MapReduce framework to handle the large scale of data in the cloud environment. Our technique is compared to different techniques, including MR-GA, MR-IDPSO, and MRPSO. The simulation results proved that our technique outperforms the other techniques.

Exploiting the coherence and entanglement of quantum many-qubit states, quantum computing can significantly surpass classical algorithms, making it possible to factor large numbers, solve linear equations, simulate many-body quantum systems, etc., in a reasonable time. With the rapid development of quantum computing hardware, many attention has been drawn to explore how quantum computers could go beyond the limit of classical computation. Owing to the need of a universal fault-tolerant quantum computer for many existing quantum algorithms, such as Shor’s factoring algorithm, and considering the limit of near-term quantum devices with small qubit numbers and short coherence times, many recent works focused on the exploration of demonstrating quantum advantages using noisy intermediate-scaled quantum devices and shallow circuits, and hence some sampling problems have been proposed as the candidates for quantum advantage demonstration. This review summarizes quantum advantage problems that are realizable on current quantum hardware. We focus on two notable problems—random circuit simulation and boson sampling—and consider recent theoretical and experimental progresses. After the respective demonstrations of these two types of quantum advantages on superconducting and optical quantum platforms, we expect current and near-term quantum devices could be employed for demonstrating quantum advantages in general problems.

Introduction

Limited evidence exists showing the benefit of magnetic resonance (MR)‐only radiotherapy treatment planning for anal and rectal cancers. This study aims to assess the impact of MR‐only planning on target volumes (TVs) and treatment plan doses to organs at risks (OARs) for anal and rectal cancers versus a computed tomography (CT)‐only pathway.

Materials and methods

Forty‐six patients (29 rectum and 17 anus) undergoing preoperative or radical external beam radiotherapy received CT and T2 MR simulation. TV and OARs were delineated on CT and MR, and volumetric arc therapy treatment plans were optimized independently (53.2 Gy/28 fractions for anus, 45 Gy/25 fractions for rectum). Further treatment plans assessed gross tumor volume (GTV) dose escalation. Differences in TV volumes and OAR doses, in terms of Vx Gy (organ volume (%) receiving x dose (Gy)), were assessed.

Results

MR GTV and primary planning TV (PTV) volumes systematically reduced by 13 cc and 98 cc (anus) and 44 cc and 109 cc (rectum) respectively compared to CT volumes. Statistically significant OAR dose reductions versus CT were found for bladder and uterus (rectum) and bladder, penile bulb, and genitalia (anus). With GTV boosting, statistically significant dose reductions were found for sigmoid, small bowel, vagina, and penile bulb (rectum) and vagina (anus).

Conclusion

Our findings provide evidence that the introduction of MR (whether through MR‐only or CT‐MR pathways) to radiotherapy treatment planning for anal and rectal cancers has the potential to improve treatments. MR‐related OAR dose reductions may translate into less treatment‐related toxicity for patients or greater ability to dose escalate.

Catalytic synergy is an unresolved activity descriptor in energy conversion reactions. Here, this study reports the synergistically enhanced intrinsic oxygen evolution reaction activity of a FeNi model catalyst modified with molybdate oxo‐anions via concertedly boosted surface/interface interactions such as interfacial charge transfer, surface intermediate adsorption, in situ phase transformation, and gas bubble evolution. Capturing such cosynergistic impact reveals the accelerated transition of oxygen deprotonation to oxyhydroxide state, ready‐to‐function Fe and Ni active sites, the instant transformation of Fe and Ni local microenvironments to γ ‐FeOOH and β  ‐NiOOH phases, and ultrafast gas bubble growth and release. The accelerated oxygen bubble evolution dynamic is monitored in operando with a decreased dynamic variation of the interfacial Faradaic resistance. Such cosynergistic molybdate modification results in a tenfold increase in oxygen evolution turnover frequency as well as a 55 mV decrease in the overpotentials to deliver 10 and 1000 mA cm−2 with respect to the FeNi‐model catalyst.

Electrochemical carbon dioxide reduction reaction (CO2RR) is a promising approach to mitigate CO2 concentration and generate carbon feedstock. Recently, the (sub‐)nanometer design of catalyst structures has been revealed as an efficient means to control the reaction process through the local reaction environment. Herein, the synthesis of a novel tin oxide (SnOx) nanoparticle (NP) catalyst with highly controlled sub‐nanoscale interplanar gaps of widths <1 nm (SnOx NP‐s) is reported via the lithium electrochemical tuning (LiET) method. Transmission electron microscopy (TEM) and 3D‐tomo‐scanning TEM (STEM) analysis confirm the presence of a distinct segmentation pattern and the newly engineered interparticle confined space in the SnOx NP‐s. The catalyst exhibits a significant increase in CO2RR versus hydrogen evolution selectivity by a factor of ≈5 with 20% higher formate selectivity relative to pristine SnO2 NPs at −1.2 VRHE. Density functional theory calculations and cation‐size‐dependent experiments indicate that this is attributable to a gap‐stabilization of the rate‐limiting *OCHO and *COOH intermediates, the formation of which is driven by the interfacial electric field. Moreover, the SnOx NP‐s exhibits stable performance during CO2RR over 50 h. These results highlight the potential of controlled atomic spaces in directing electrochemical reaction selectivity and the design of highly optimized catalytic materials.

Designing catalysts to accelerate the conversion of soluble lithium polysulfides (LiPSs) is regarded as a promising strategy to inhibit the shuttle effect, improving cathode performance of lithium–sulfur batteries (LSBs). Herein, a bifunctional Ni/Zn dual‐doped CoSe2 is designed to enhance the catalytic effect of CoSe2. Specifically, Ni functions better in catalyzing the conversion of LiPSs into Li2S with shorter CoS bond and longer SS bonds than Zn, while Zn demonstrates a better catalytic effect for Li2S decomposition with reduced Li2S decomposition barrier and elongated LiS bonds than Ni. Those endows Ni/Zn dual‐doped CoSe2 with bifunction in catalyzing conversion reaction of LiPSs and Li2S precipitation as well as the decomposition of Li2S, originating from the modified molecular structure of LiPSs and Li2S. As a result, the sulfur cathode with Ni0.1Zn0.1Co0.8Se2 achieves a rate capability of 681.74 mAh g–1 at 2C, and a cycling stability for 400 cycles with a decay rate of 0.065%. This work provides an effective way to improve catalytic effect of transition metal compounds for advanced LSBs by homogenous dual doping.

The most emerging 2D‐materials‐based heterostructures are considered promising candidates because of their multifunctional logic applications for electric and optoelectronic devices. Here, a high gate tunable rectification in van der Waals heterostructure composed of n‐type rhenium disulfide (n‐ReS2) and p‐type germanium selenide (p‐GeSe), using pure Ohmic contacts, is reported. The large rectification ratio (RR) deprived of any Schottky contribution is tuned up to 4 × 105 because of the sharp interface of p‐GeSe and n‐ReS2. The sheet‐thickness effect over the rectification is also observed in the p‐GeSe/n‐ReS2 heterostructure as well. The profound photovoltaic measurements under lights of different power intensities depict a high photo responsivity of 3.9 × 103 A W−1 with an external quantum efficiency of 87% and specific detectivity (D* = 1.5 × 1012). The fast growth (16.6 µs) and decay times (12.3 µs) are extracted by the exponential rise and decay fitting. Moreover, practical applications of the p‐GeSe/n‐ReS2 heterostructure devices are exhibited by observing inverter behavior and high‐frequency switching operations, which is also the breakthrough of this research. Fabrication of such smart devices based on transition metal dichalcogenides (TMDs) van der Waals heterostructures may enhance the energy harvesting as well as the multifunctional logic switches.

Cellulose exhibits outstanding chemical stability, nontoxicity, and renewable ability and is regarded as a candidate for next‐generation sustainable materials. After the nanofibrillation of cellulose, cellulose nanofiber (CNF) exhibits unique optical properties, good mechanical strength, and a high aspect ratio. It is suitable to be a matrix for the photocatalysts immobilization and applied in pollutant removal owing to its solvent resistance. Combined with 1D TiO2, the network structure may be expected and beneficial for the charge transport of TiO2 nanofibers. In this study, the flexible CNF composites film incorporated with various sizes and morphology of TiO2 photocatalysts is fabricated. The relationship between the chemical and physical properties of the composite film and morphological features are discussed. The GIWAXS analysis shows that the entanglement of self‐precipitated Ag‐doped TiO2 NFs (STNFs) and CNF induce the densely hierarchical stack and regular stacking orientation. For 30 day solvent resistance tests, various CNF composite films show outstanding stability in the acetone and dimethylformamide (DMF). In the photodegradation of methyl orange in ethanol, STNF/CNF film presents a high degradation efficiency of 87% and shows excellent stability of morphology and activity after three cycles. For volatile organic compound degradation, the degradation efficiencies toward methanol and DMF vapor are higher than 90%.

A strategy for the synthesis of isoquinolylselenocyanates and quinolylselenocyanates through electrophilic selenocyanogen cyclization has been developed. The feature of this reaction is that the sequential process was induced directly by generated in situ pseudohalogen (SeCN)2 generated in situ. Additionally, the obtained selenocyanates allowed functional group diversification, which could be potential intermediates for valuable compounds.
