A study on triple diffusive magneto convection is made for a fluid – porous composite system with rigid-rigid boundaries insulated to temperature and concentration. The porous layer of the composite system is modeled using Darcy–Brinkman model. The method of regular perturbation approach is employed to find the eigen-value for the problem considered. The critical Rayleigh number as criterion for the onset of convection is derived for step function, salting below and desalting above salinity profiles. The effect of various physical parameter on the onset of convection is graphically depicted and the stability of the system is analyzed.

Published: March 2023

Banana aphid Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is widely known as the main vector of Banana bunchy top virus (BBTV). It had been reported that banana aphid could live on alternative hosts belong to Family Araceae, and become important issue since Araceous plants are commonly found surrounding banana cultivations. Research had been conducted to study the morphometrics and biological characteristics of banana aphids living on various species of Araceous plants. The results showed that Araceous plant species could influence the morphometric and biological characteristic of banana aphids, indicated by the significant difference in some biological characteristics such as life cycle, life span, reproductive period, and fecundity. The average life span of banana aphids living on Araceous plants ranged from 22.80 to 47.90 days, it was shorter than the one that of lived on a banana plants. P. nigronervosa was able to develop a bigger colony when the aphid lived on Araceous plants, especially when they were transferred to Bogor taro where their fecundity reached 63 nymphs per female. Araceous plants also affected the morphometric of P. nigronervosa indicated by smaller size of the aphids, compared to those living on banana plant. The ability of banana aphid to live and reproduce in various Araceous plants would be beneficial to the development of control strategies of BBTV.

Published: March 2023

Forage maize (Zea mays L.) yield and nutritional quality fluctuate markedly in Northern Europe due to weather conditions. A field experiment was conducted in Southern Finland (Helsinki, 2018–2020) and in Central Finland (Maaninka, Kuopio, 2019–2020) to study the effect of harvest time and use of mulch film, in order to optimize the dry matter (DM) yield and quality. Treatments included oxo-biodegradable mulch film and no mulch, and three harvest times (the latter only in Helsinki). Mulch film increased DM yield on average by 2.3 Mg ha-1 in Helsinki and by 3.8 Mg ha-1 in Maaninka. Mulch film had a minor effect on the quality, and overall, the quality improved, although DM yield accumulation had already ceased. Nevertheless, the starch contents fluctuated and remained mostly below the target rate – 300 g kg-1 DM – especially in Central Finland. The results indicate that mulch film improves forage maize yield, but a late harvest is still required to improve forage quality. However, climate conditions still restrict starch accumulation to ears in Northern European climate conditions, especially in the important milk production area in Central Finland.

Published: March 2023

The quality of human resources of every nation greatly determines its development. Therefore, a well-functioning recruitment and selection system can screen and identify candidates with the skills, qualifications and professional competence to effectively perform public and civil servant tasks. Given this context, this study examines the role of recruitment and selection practices in public service delivery focusing on the perspectives of the Public Service Commission (PSC). The following objectives were established; to examine the recruitment and selection practices and structures, to assess the effect of recruitment and selection on public service delivery, to investigate public recruitment and selection strategies and to assess the challenges affecting effective public recruitment practices at PSC. In order to assess the effectiveness of different recruitment and selection practices of civil and public servants, an exploratory case study design was used whereby qualitative data was collected using interviews and questionnaires to provide an insight and identify the extent to which the Public Service Commission applies recruitment and selection practices. The study used a simple random sampling technique and the sample size of this research was 40. The findings revealed that the more effectively MDAs recruit and select candidates, the more likely they are to hire and retain satisfied employees. Hence, investing in the development of a comprehensive and valid selection system is critical for better service delivery. The result showed that PSC has a structured recruitment and selection system to recruit and select personnel for public service. The better and clearer recruitment/selection processes, the more qualified staff are hired. The findings further revealed that quality human resource, credible and efficient recruitment process backed by better recruitment strategy are critical to improved public service delivery. By extension, the findings showed serious challenges in human resources in the public sector as recruitment and selection procedures tend to conflict with the requirement of ethic representativeness. In conclusion, the study has established that recruitment and selection is a key component of human resource management and thus a building block of national development and success.

Published: March 2023

There have been pros and cons to learning grammar concerning Second Language Acquisition. This paper aims to investigate Hospitality and Tourism (HT) students’ and workers’ perceptions of the significance of English grammar which has not been widely discussed. This article reports a mixed-method study that was conducted using an online survey and involving 50 HT students and 50 HT workers across Indonesia. Interviews with 2 Human Resource Managers of international hotel chains were also performed to provide stronger validation. The findings revealed that HT students and workers do not hold a positive perception of learning grammar and should not comprehensively learn English rules since grammar mastery will insignificantly impact employability and career performance for most positions in that sector. However, it is suggested that those in higher positions learn the 6 most commonly used tenses to avoid misunderstandings that, to some degree, link to job promotions. Results also suggest that teachers of ESP for Hospitality prioritize students’ speaking fluency, listening, and vocabulary comprehension using the CLT and PBL teaching approaches. The research results are expected to build a more positive attitude toward English learning, thus fostering a better quality of human resources in the hospitality industry.

Published: March 2023

We examine the labor market consequences of recent global supply chain disruptions induced by COVID-19. Specifically, we consider a temporary increase in international trade costs similar to the one observed during the pandemic and analyze its effects on labor market outcomes using a quantitative trade model with downward nominal wage rigidities. Even omitting any health related impacts of the pandemic, the increase in trade costs leads to a temporary but prolonged decline in U.S. labor force participation. However, there is a temporary increase in manufacturing employment as the United States is a net importer of manufactured goods, which become costlier to obtain from abroad. By contrast, service and agricultural employment experience temporary declines. Nominal frictions lead to temporary unemployment when the shock dissipates, but this depends on the degree of monetary accommodation. Overall, the shock results in a 0.14% welfare loss for the United States. The impact on labor force participation and welfare across countries varies depending on the initial degree of openness and sectoral deficits.

Evaluación de la adsorción de CO₂ en un biocompósito basado en lignina y las redes metal orgánicas HKUST-1 y UiO-66-NDC
Authors:   , López Monreal Brian Alexis
Published: March 2023

La adsorción con materiales porosos es uno de los métodos más útiles para la captura de CO₂, dicha técnica presenta ventajas como una gran capacidad de almacenamiento, su bajo costo y bajo consumo energético. Con este propósito, se propuso la síntesis de materiales biocompósitos basados en las redes metal orgánicas (MOFs) HKUST-1, UiO-66 y UiO-66-NDC, soportadas sobre la superficie del material biológico lignina. Las MOFs son materiales cristalinos tridimensionales ampliamente estudiados que ha demostrado tener una de las mayores áreas específicas para adsorción de compuestos, con respecto a otros materiales adsorbentes. Pero aún con esta característica algunos presentan desventajas como: ser inestables en sistemas acuosos y tener estabilidad térmica moderada. Sin embargo, estas características pueden mejorarse a través del soporte del MOF sobre un material adecuado. Para mejorar la estabilidad de las MOFs se eligió la lignina, un material biológico que comúnmente se obtiene como su producto en la producción de papel. Este resulta útil como soporte debido a que en estado natural dicho material tiene como función clave la unión de las fibras que conforman la estructura de los organismos vegetales. Además, entre las aplicaciones más extendidas de la lignina se encuentra su uso como compósito. Siendo la lignina la parte del compósito que aporta rigidez estructural al material, con lo cual se espera mejorar la estabilidad mecánica y química del MOF. Para la síntesis de los biocompósitos, se emplearon dos metodologías, una mezcla mecánica de los materiales previamente obtenidos y otra mezcla in situ (llevada a cabo durante la síntesis de las redes metal orgánicas), tras llevar a cabo estos procesos se obtuvieron dos tipos de materiales biocompósitos. El material biocompósito con UiO-66-NDC no se logró obtener. La caracterización de las propiedades fisicoquímicas de los materiales precursores se realizó mediante las técnicas de XRD, FT-IR, SEM y TGA, lo cual permitió determinar algunas propiedades como la morfología, la estructura, los grupos funcionales y la estabilidad térmica tanto d ellos precursores como de los biocompósitos obtenidos. La evaluación de los materiales biocompósitos se realizó mediante fisisorción de CO₂ con el fin de obtener los datos que permitieron verificar que los biocompósitos que se sintetizaron presentaron una capacidad de adsorción de CO₂ similar a la de la MOF de referencia. Sin embargo, aumenta la estabilidad térmica, esto debido a la sinergia en la estabilidad de los materiales precursores.
Static friction of normal and reversed metal–polymer sliding pairs
Authors: Opalka Mariusz
Published: March 2023

The frictional cooperation of materials with different hardnesses occurs in machine elements in one of the following two variants: simple or reversed friction pairs. For a simple sliding pair, the sliding materials' deformation area (contact area) does not move over the surface of the polymeric element during their interaction. In the case of reversed pairs, the contact surface changes its position as it moves over the surface of the polymer element. Tribological tests of selected sliding pairs (polymer on steel or steel on polymer) in static friction were carried out on a tribotester for tests in a reciprocating motion. The polymers selected for the research were popular sliding materials in engineering applications: ultra-high molecular weight polyethylene (PEUHMW), polyoxymethylene (POM) and polytetrafluoroethylene (PTFE). These materials cooperated with the C45 steel at different unit pressure (P = 0.5; 1; 2 [MPa]) in dry friction conditions. The measurement results showed a significant influence of the material combination variant (metal–polymer, polymer–metal) on the value of the friction coefficient. In all tested material combinations in which the steel sample (pin) slid over the polymer plate, the friction coefficient was higher than when the polymer sample worked with the steel plate.
Effects of GGBS and Fly Ash in Binders on Soil Stabilization for Road Construction
Authors: Lindh Per , Lemenkova Polina
Published: March 2023

In this paper we propose a new technique of soil stabilization for road construction based on using new alternative binders. The project aims to evaluate the effects of alternative additive materials in soil stabilization contexts for road construction. The alternative binders (slag, energy ash and bio ash as new alternative road construction material) have been used to complement the traditional binders (cement and lime). The project used five binders and evaluated their effects on soil strength. The proposed method comprises advantages of using the alternative binders which are the residual products contributing to a lower environmental impact. The results have shown that only slag has significant effects on the strength of the stabilized soil, while bio ash and energy ash make a marginal contribution to the increase of strength. This is caused by the twofold reasons. First, the effects of the amount of ashes that should reach a certain threshold with respect to the total amount of binder that must be exceeded to have the effect of the soil mixture. Second, the bio fly ash was stored and it was not completely fresh which may have contributed to the carbonation during the storage period and results in a lower hardening ability. Based on the results of the study we recommend the use of bio fly ash as a supply material andfor its amount to be adjusted so the storage period is not too long. This study verified the effects of slag, cement and lime on stabilization of soil for road construction.

Authors: Oloriegbe Tunde , Joshua Odeleye A. , Abubakar Adeyi A.
Published: March 2023

It has been noticed that the concentration of particle pollutants in major nodal points in Zaria metropolis has continued to grow as the traffic volume increases. The concentration of particulate matter and meteorological data was measured within the Zaria metropolis and was limited to major ways within the town which include Kwangila, PZ, Kasua Mata, Agoro and Kofar Doka. The concentrations of the Particulate Matter in different particle sizes (P0.3, P0.5.P1.0, P2.5 and P5.0) were measured using particle counter, at each sampling point for 3hrs during the morning peak hours (7:00am to 10.00am), for 3hrs during the afternoon off peak hours (11.00am to 2:00pm) and for 3hrs for the evening peak hours (4:00 to 7:00pm) after a comprehensive traffic volume of vehicles plying the sampling points had been done for one month. The average traffic volume for the peak period (morning) across the five sampling points ranged from 2701-3060 while that of the evening peak hours ranged from 2676-3651. The average traffic volume for the off peak (afternoon) ranged from 1777-2255 with kwangila recording the highest traffic volume for both peak and off peak periods. The impact of traffic density on the concentration of particulate matter measured showed that increase in traffic led to a corresponding increase in the concentration of particulate matter recorded for both peak and off- peak periods. The P2.5 was used as bases for comparison with the AQI standard for peak and off peak periods. For peak hour session, the air quality at Kwangila, Kasua Mata and Agoro was classified as unhealthy and hazardous while that of PZ and Kofar Doka was classified unhealthy to people with heart and lungs diseases. The concentration of PM obtained for off-peak period for all the sampling points was classified moderate and safe when compared with AQI standard. In this regard, there is a need to not only promote public transportation with larger capacity of passengers but to also improve the public transportation system. This will reduce greenhouse gas emissions by providing a convenient option to reduce unnecessary driving and by lowering emissions per passenger kilometer travelled. The use of non-motorized means of transportation would also help in curbing excessive release of pollutants into the atmosphere. Planting of Trees along major ways to trap and absorb pollutants is another option of reducing the amount of pollutants in the atmosphere. The use of older vehicles should be discouraged. The older a vehicle is the more the tendency to emit more pollutants.
Using Machine Learning Techniques to Incorporate Social Priorities in Traffic Monitoring in a Junction with a Fast Lane

Published: March 2023

Traffic lights monitoring that considers only traffic volumes is not necessarily the optimal way to time the green/red allocation in a junction. A “smart” allocation should also consider the necessities of the vehicle’s passengers and the needs of the people those passengers ought to serve.

This paper deals with a “smart” junction, where several cars approach the intersection from different directions and a traffic light is set to comply to a sequence of time intervals of red and green lights in each direction. The novel approach presented here is based not only on traffic congestion parameters, but also on the social and economic characteristics of the passengers (e.g. a handicapped person, a medical doctor, an employee who is extremely required in a certain organization due to an emergency situation). This paper proposes to enhance the smart junction with a fast lane, which has a flexible entry permit based on social and economic criteria. Machine learning (specifically, Reinforcement Learning (RL)) is added to the junction’s algorithm with the aim of optimizing the social utility of the junction. For the purposes of this study, the utility of the junction is defined by the total social and economic potential benefits given a certain red/green time allocation is set. This is defined as the measure of the reward function which contains positive factors for vehicles which crossed the junction or advanced their position and a negative factor for vehicles which remains in their positions. In addition, a weight value for the vehicles with high priority is also part of the equation.

A simplified version of the smart junction has been used, serving as a model for incorporating RL into the “smart’ junction with Fast Lane (FL). Specifically, the Q-Learning algorithm is used to maximize the reward function. Simulation results show that prioritizing high priority vehicles via FL is influenced by the weights and factors given to the reward components. Farther research should enhance the “Smart” junction with FL to a more complex and realistic one using a varying amount of vehicles crossing the junction.

Authors: Agbesi Komi Arnold , Louis Appiah Gyekye
Published: March 2023

The increasing rate of call-drop among wireless cellular networks has become a headache for subscribers of mobile voice networks in Ghana. Despite the many studies that have been carried out on call-drop, most of them have failed to examine call-drop probability rates, a key metric of tackling the issue of call-drop. This study combines the probability distribution function of call-drop and maximum likelihood estimator to estimate call-drop probability rates among the wireless cellular networks in Ghana. The call-drop of the networks was, first of all, fitted to a probability distribution. The call-drop probability rate was then estimated using the maximum likelihood estimator of the fitted distribution. The call-drop probability distribution of Airtel-Tigo, Vodafone, and Glo follow the Geometric probability distribution, while that of MNT follows the Negative Binomial probability distribution. The call-drop probability rate of MTN is 7.6%, Vodafone is 3.3%, Airtel-Tigo, and Glo is 3.0%. These call-drop rates are found to be outside the prescribed NCA's acceptable limit of less than 3 %.

Data were analysed using the ordinary least squares approach at a 0.05 level of significance. Data analysis was done with the help of Eviews and presented in tables. The research findings were that loan uptake has a negative significant effect (Î² = -0.0099, p = 0.0391) on return on investment in commercial real estate. As the frequency of loan uptake increases, the return on investment tends to decrease. The study concludes that frequent loan uptake reduces the return on investment due to the added cost of borrowing. This research study recommends that awareness be created of the need to use other financing options that are cheaper in the long run. This study contributes to the body of knowledge by providing the link between loan uptake and returns on investment in commercial real estate in Kenya.

Published: March 2023

Heuristic decision-making is part of strategic decision-making. This study sought to examine the status of heuristic decision-making and organizational performance of Kenya Power Company. Moreover, the extent to which heuristic decision-making influenced the performance of the aforementioned company was analyzed. The study was conducted against a backdrop of acknowledged performance challenges. The poliheuristic theory of decision-making and the balanced scorecard model guided the study. A descriptive research design was adopted. The 31 senior management staff of Kenya Power were targeted. A census design was employed to obtain the study participants. The data collected from these participants were analyzed with the assistance of the Statistical Package for Social Sciences. Descriptive statistics, as well as inferential statistics, were used to analyze the collected data. It was revealed that the relationship between heuristic decision-making and organizational performance was positive though weak (rs = 0.340) and not statistically significant (p = 0.104 > 0.05). The effect of heuristic decision-making on organizational performance was established not to be statistically significant (F1,22 = 3.181; p = 0.088 > 0.05). Consequently, the null hypothesis (There is no significant effect of heuristic decision-making on the performance of Kenya Power) was not rejected. Instead, it was also concluded to be true. Heuristic decision-making was inferred to have minimal effect on the organizational performance of Kenya Power. It was recommended that senior managers should have a duty to ensure that the heuristics embraced by the company are reliable in making pertinent decisions.

Internal controls are essential determinants of financial distress in any devolved government worldwide. The devolved governments in Kenya recorded a dwindle in their own source return from 11.7 percent in 2013/14 to 8.8 percent in 2016/17. This research sought to establish the effect of internal controls on the performance of devolved governments in Kenya by adopting a correlational research study. The target population was 423 respondents from the 47 devolved governments in Kenya. Stratified random sampling was used where the sample size was 381 respondents after 38 respondents were excluded and used in the pilot study with a response rate of 80.7%. Primary data were gathered by the use of a structured questionnaire. Data analysis involved descriptive and inferential statistics in determining the trend of the study variables and prediction of variables, respectively. Findings of the study were presented using tables and figures, while regression analysis disclosed that the calculated p values of internal controls (p=0.002) were significant (p˂0.05). Therefore, the scholar failed to reject the null hypothesis connoting that internal controls significantly had an effect on the performance of the devolved government in Kenya. The study commends that devolved governments should step up and ascertain that internal controls are in place to improve service delivery to the people on the ground.

Adoption and usage of ICT in banking services delivery aim to depopulate the conventional banking halls congestions. However, banking service users still populate the banking halls with long and endless queues. Currently, financial institutions in Tanzania have failed to utilize ICTs opportunities in delivering high-quality banking services. As a result, the study was conducted to assess the influence of telephone banking technology usage on the quality of banking services in Tanzania. Specifically, the study analyzed the simplicity of the technology to the users, if the technology is friendly to use, and the reliability and affordability of telephone banking technology to the users. The study was guided by Technology Acceptance Model Information System Success Model to elaborate on the basis for customers' usage of telephone banking technology in baking services delivery. Moreover, the financial inclusion theories, such as the dissatisfaction theory of financial inclusion and the system theory of financial inclusion, were used. The case study research strategy and quantitative research design were adopted. The data were collected from commercial banks located in Mwanza city, Tanzania. A non-probability sampling procedure was adopted, particularly convenience and purposive sampling. The total number of respondents was 277, of which 52 were bank officials, 215 were bank customers, and 10 were representatives from the Bank of Tanzania. The questionnaires were used for data collection. The data were descriptively and inferentially analyzed with the aid of the SPSS statistical package. According to the findings, there is a statistically significant influence of TP banking on service delivery. Moreover, the findings show that commercials use TP banking to provide information about banking services. As a result, the customers perceive TP banking technology as a technology of their choice, convenient, reliable, effortless, and easier to use and hence useful for the delivery of banking services. However, the limitation of withdrawal amount discourages users of the technologies when they need a large withdrawal amount. In short, TP banking influences banking service delivery in commercial banks by increasing geographical reach, enhancing performance and reducing transaction processing time. It is recommended that commercial banks should focus on the full utilization of opportunities that are provided by the use of telephone banking, such as the situation whereby the customers own the telephones for other uses. However, they can use telephone devices in banking.

Published: March 2023

Despite Homa Bay County in Kenya spending 70% of its total budgetary allocation on recurrent expenditures like salaries and allowances, it was still struggling with poor service delivery and staff performance issues. Past empirical studies on non-monetary rewards have not established a link between non-monetary rewards and employee performance. Therefore, this study aims to examine the effect of non-monetary rewards on employee performance in Homa Bay County, Kenya. The study population constitutes 373 employees of HBCG, out of which a sample of 146 respondents was selected using stratified sampling techniques. Management staff, including branch managers, assistant managers, and supervisors of the five Nakumatt branches in the Western region, were selected for the study. A sample of 73 respondents was selected using saturated sampling techniques, while the remaining 10 were used for the pilot study. The findings revealed that non-monetary rewards explained a 62.7% (R2 =0.627) variation in employee performance. The study concludes that employee recognition, training, and development are both critical antecedents of employee performance in Homa Bay County, Kenya. The results of the study may be useful for the County Government administration's human resource reward policy formulation that might enhance employee performance and effective service delivery.
