Polyaromatic Hydrocarbons Levels and Bacterial Load on Soil after Consistent Disposal of Untreated Hairdressing Saloon Effluent in Lokoja, Kogi State, Nigeria
Authors: Amupitan P. , Yakubu J. M. 
Published: April 2023

This study estimated polyaromatic hydrocarbons levels and bacterial load on soil after thirty day (30) days consistent disposal of untreated hairdressing saloon effluent in Lokoja, Kogi State, Nigeria using standard methods. A non-polluted soil sample was also collected which served as the control for this experiment. The total heterotrophic bacteria count was determined. Toxicity analysis was carried to determine the effect of the effluent on soil bacteria. The soil samples were also was analyzed for the presence of polyaromatic hydrocarbon using gas chromatography with mass spectrometry. The polyaromaic hydrocarbon (PAHs) detected in the test soil sample were 45.02ng/g Biphenyl, 28.23ng/g Benzo[a]pyrene, 12.05ng/g Anthracene, 23.00ng/g, and 5.07ng/g Phenanthrene. 2.01ng/g of Biphenyl was detected in the control garden soil. Bacteria counts from the contaminated soil range from 1.0 x102 ± 1.10 to 4.0 x 102 ± 0.11. The counts from the control soil sample range from 2.0 x103 ± 0.20 to 8.2 x103 ± 0.20. The control soil sample had a higher value compared to the test soil samples. Bacteria species isolated from these soil samples were: Serretia sp., Klebsiella sp., Escherichia coli, Pseudomonas sp., Staphylococcus sp. Pseudomonas sp. and Staphylococcus sp had increased percentage occurrence. The acute and chronic toxicity test showed a decline in the bacterial count, which could have occurred due to the presence of PAHs from Salon effluent. I was observed a constant release of PAHs into the soil, which poses a serious threat to the survival of soil bacteria, will alter the various beneficial roles these bacteria play in the soil ecosystem.

Published: April 2023

We present and analyze an example of activity aiming at introducing graphical language and standards to students of the first year bachelor's in architecture. Our example concerns the 2D representation of an architectural object, an essential competency in the architect's profession, and specifically deals with roofing systems made up of vaults generated by cylinders and their intersections. It is a first attempt to create activities that involve all students regardless of their different levels of geometric understanding and of familiarity with graphic language; in particular, this example exploits the introduction of physical or virtual models to support the mathematical thinking of students in completing the task and takes place during regular lesson times, without modifying or adding mathematical subject contents. Research literature on mathematical modeling, in particular on the so-called prescriptive one, provides us tools to frame and implement our study case; it also allows presenting mathematical modeling as a goal in an extra-mathematical educational context.

On setwise betweenness
Authors: Shakir Qays R. 
Published: April 2023

In this article, we investigate the notion of setwise betweenness, a concept introduced by P. Bankston as a generalisation of pointwise betweenness. In the context of continua, we say that a subset C of a continuum X is between distinct points a and b of X if every subcontinuum K of X containing both a and b intersects C. The notion of an interval [a,b] then arises naturally. Further interesting questions are derived from considering such intervals within an associated hyperspace on X. We explore these ideas within the context of the Vietoris topology and n-symmetric product hyperspaces on all nonempty closed subsets of a topological space X, CL(X). Moreover, an alternative pointwise interval, derived from setwise intervals, is introduced.
Hybrid topologies on the real line
Authors: Richmond Tom 
Published: April 2023

Given A ⊆ ℝ , the Hattori space H(A) is the topological space ( ℝ , τA ) where each a ∈ A has a τA -neighborhood base { ( a − ε , a + ε ) : ε > 0 } and each b ∈ ℝ − A has a τA -neighborhood base { [ b , b + ε ) : ε > 0 } . Thus, τA may be viewed as a hybrid of the Euclidean topology and the lower-limit topology. We investigate properties of Hattori spaces as well as other hybrid topologies on ℝ using various combinations of the discrete, left-ray, lower-limit, upper-limit, and Euclidean topologies. Since each of these topologies is generated by a quasi-metric on ℝ, we investigate hybrid quasi-metrics which generate these hybrid topologies.

Authors: Pichardo-Mendoza Roberto , Ríos-Herrejón Alejandro 
Published: April 2023

For a Tychonoff space X, the lattice UX was introduced in L. A. Pérez-Morales, G. Delgadillo-Piñón, and R. Pichardo-Mendoza, The lattice of uniform topologies on C(X), Questions and Answers in General Topology 39 (2021), 65-71.
In the present paper we continue the study of UX. To be specific, the present paper deals, in its first half, with structural and categorical properties of UX, while in its second part focuses on cardinal characteristics of the lattice and how these relate to some cardinal functions of the space X.
A Parent-Mediated Anxiety Intervention Specifically Tailored for Autistic Preschoolers: A Pilot Study
Authors: Simpson Kate , Adams Dawn , Malone Stephanie , Tucker Madonna , Rapee Ron M. , Rodgers Jacqui 
Published: April 2023

AbstractImportance: Autistic children experience reduced participation in life activities. One factor that may contribute to their reduced levels of participation is anxiety, which is identified at higher rates among young autistic children than among their neurotypical peers. Anxiety is also strongly associated with sensory overresponsivity and has a considerable impact on daily functioning.Objective: To determine the feasibility, acceptability, and usefulness of a small-group, parent-mediated intervention to prevent and reduce anxiety.Design: Pre–post.Setting: University research center.Participants: Three parents of autistic children (ages 4–7 yr).Outcomes and Measures: Parents completed a six-session group training program. Parents completed an anxiety scale for their child before and after parent training. At the end of training, parents participated in a focus group and were interviewed 4 mo after training.Results: Positively received aspects of the intervention were the benefits of a small group, composed of parents of autistic children, run by a facilitator with expertise in autism and anxiety. Parents gained knowledge, resulting in “taking a different approach” with their child and “seeing an interplay between anxiety and autism.” After the intervention, parents reported a reduction in children’s reported anxiety levels.Conclusions and Relevance: Knowledge of autism and anxiety acquired during a parent-mediated group increased parents’ understanding of their child’s behaviors and assisted them in supporting their child’s participation. Further research, including larger studies, is required to determine the effectiveness of this intervention.What This Article Adds: The findings from this research provide preliminary support for the adaptation of an existing parent intervention (Cool Little Kids) to reduce anxiety among autistic children. Parents reported an increased awareness and understanding of anxiety and of the interplay between anxiety and autistic traits.Positionality Statement: This article uses the identity-first language autistic people. This nonableist language describes their strengths and abilities and is a conscious decision. This language is favored by autistic communities and self-advocates and has been adopted by health care professionals and researchers (Bottema-Beutel et al., 2021; Kenny et al., 2016).
Father–Child Playfulness: A Secondary Analysis of a Multiple-Baseline Single-Subject Study of Three Children With Autism Spectrum Disorder
Authors: Waldman-Levi Amiya , Kuhaneck Heather 
Published: April 2023

AbstractImportance: Ayres Sensory Integration® (ASI) is commonly used with children on the autism spectrum to promote sensory processing and improved occupational performance, including play. To date, there has been no explicit effort to examine improvements in playfulness through ASI.Objective: To explore whether ASI, coupled with parent training, improves child playfulness and fathers’ support of child playfulness.Design: Single-subject A–B–BC design secondary analysis of a nonconcurrent multiple-baseline study.Setting: Occupational therapy clinic.Participants: Three father–child dyads; children were ages 3 to 6 yr, with autism spectrum disorder (ASD) and documented sensory processing concerns.Intervention: After a baseline phase, each child received at least 24 sessions of ASI, and fathers received parent training focusing on sensory processing issues and play via an online presentation.Outcomes and Measures: The Parent/Caregiver’s Support of Children’s Playfulness and the Test of Playfulness.Results: Visual analysis of the baseline phase, ASI phase, and ASI with parent training phase shows that all 3 fathers demonstrated an increase in the way they supported their child’s playfulness; however, this change was not maintained. Children’s playfulness fluctuated, reaching a peak after fathers received training, but none of the children maintained that change.Conclusions and Relevance: Additional support by the therapist is required for fathers to learn and use new strategies to promote consistent change in child playfulness during play. Pilot data can be used to inform future studies.What This Article Adds: Occupation- and family-centered frameworks may be useful in guiding practice when working with families of children with ASD.
Improving Executive Functions Using the Engineering Design Process: A Peer-Mediated Problem-Solving Approach for Autistic Adolescents
Authors: Murthi Kavitha , Patten Kristie 
Published: April 2023

Abstract
Executive functions—specifically, problem-solving skills—are crucial for school success. Challenges in these functions faced by autistic adolescents are often unrecognized or viewed through a behavioral lens that requires correction or normalization. A lack of development of higher order problem-solving skills leads to increased instances of secondary mental health issues, creating further behavioral and social challenges. We propose using the Engineering Design Process (EDP), a flexible, cyclical, top-down, self-sustaining approach that uses peer mediation to teach group problem-solving skills. We then position this cycle within existing occupational therapy models to demonstrate its adaptability and flexibility, describe the distinct features of this problem-solving strategy, and present a real-world case study in which the EDP is used as a problem-solving approach in an after-school program. The EDP develops crucial social and interpersonal skills using interest-driven occupations and can be organically used as a group strategy. This article uses the identity-first language autistic people. This nonableist language describes their strengths and abilities and is a conscious decision. This language is favored by autistic communities and self-advocates and has been adopted by health care professionals and researchers (Bottema-Beutel et al., 2021, Kenny et al., 2016).
Convergence of food consumption across Ukrainian regions: approach using spatial panel data models
Authors: Osypova Olha , Horna Maryna , Vashchaiev Serhii , Ishchuk Yaroslava , Pomazun Oksana 
Published: April 2023

Purpose. The article studies the convergence between the regions of Ukraine in terms of the basic foodstuff consumption per capita during 2000–2019, taking into account the effects of spatial interaction across regions.
Methodology / approach. The convergence analysis between regions of Ukraine is based on the concept of β-convergence which can be tested using spatial econometric models namely spatial autoregressive models and spatial error models. The need for considering spatial interaction can be explained by the fact that regions are characterized by constant interaction with each other. Therefore, region should not be considered as isolated objects in space in empirical research with usage of panel data. Ignoring the spatial interaction between regions and using standard evaluation procedures can reduce the reliability and validity of the obtained results to some extent.
Results. The results of our calculation confirm the process of β-convergence of average per capita consumption of all food groups, which means that food consumption in regions with an initial low level of consumption is growing faster than in regions with high initial levels of consumption. Also, as part of the use of spatial econometric models the convergence process was determined to be influenced by spatial interaction between regions while the influence of neighbouring regions has a positive effect on food consumption in particular region.
Originality / scientific novelty. The article further develops the main ideas of modeling interregional differentiation based on convergence theory and for the first time, spatial econometric models were used to estimate β-convergence of Ukrainian regions by the levels of consumption of basic foodstuffs.
Practical value / implications. The approach proposed by the authors and the obtained results can be used both by state authorities on agrarian policy and food issues, and by enterprises of the agricultural sector in the analysis and forecasting of trends in the consumption of basic foodstuffs at the regional level; when planning the production, processing and delivery of agricultural products, when planning state or regional trade policy in the field of food. At the same time, the inclusion of spatial effects in the model of evaluating convergence will allow policymakers to take into account the geographical features of the convergence process and, accordingly, make more informed decisions to reduce the differentiation of regions of Ukraine by the levels of consumption of basic foodstuffs.

Published: April 2023

Purpose. This study aimed to provide the central bank of Bangladesh with some empirical data on the impact of bank agricultural credit on agricultural output as a priority sector lending.
Methodology / approach. Econometric analysis is applied to discover the nature of the relationship between banks’ agricultural credit and agricultural gross domestic product (GDP) and to find the impact of bank agricultural credit on agricultural output in Bangladesh. Data are extracted from secondary sources, i.e., Bangladesh Bank, Bangladesh Bureau of Statistics, World Bank, and Ministry of Finance for 1991 to 2018. Time-series data are analyzed using the Augmented Dickey–Fuller (ADF) unit root test and the Johansen cointegration test and later examined with Vector Error Correction Model (VECM).
Results. The Augmented Dickey–Fuller unit root test confirmed that the variables were non-stationary at their level data and became stationary after taking their first difference value. Since the variables are integrated at I(1), we performed the Johansen Co-integration test. Subsequently, one co-integration equation was found, and Vector Error Correction Model estimation was done afterwards. According to the results of VECM estimation, bank agricultural credit, pesticide consumption, and use of cropped areas have long-run relation with agricultural output.
Originality / scientific novelty. This study reveals the nature of relationship and assessment of the impact of bank credit on agricultural GDP with empirically valid techniques and tools. In this context, the data from Bangladesh remains very rare. Moreover, for those works which have been done in the context of Bangladesh, appropriate methods and techniques are not always inherent. Hence, this significant research gap is addressed in our present study. Thus, we expect that the findings of this study from Bangladesh based on empirically valid standard techniques can incrementally contribute to the existing literature.
Practical value / implications. Findings of this research, can be used as an information basis by the central bank of Bangladesh. Based on the findings of this research, Bangladesh Bank should initiate new policies and programs regarding agricultural credit for the projected increase in agricultural GDP in Bangladesh.

Authors: Kondratska Liliya 
Published: April 2023

Purpose. The article analyzes the practical aspects of the functioning of the restaurant business in the COVID-19 pandemic conditions.
Results. Nowadays, Ukraine and the entire world live through a difficult period. It is caused by the global COVID-19 pandemic. The situation with the spread of the COVID-19 pandemic has changed the life of each person almost completely. The tourism industry suffers a particularly crushing blow. The hotel and restaurant business have been intensively developing lately (2015–2019) in Ukraine, employing about half of the population. The emergency has almost stopped the development of this area and inflicted enormous economic losses for both consumers of tourist services and those employed in the industry. The hotel and restaurant business entities face the problem of creating an efficient mechanism to secure quick reaction to emerging impacts in conditions of the pandemic, introduction of quarantine measures, and adverse external environment. The article is focused on the research of the restaurant business companies’ functioning conditions. It assesses the impact of quarantine measures caused by the pandemic on the companies’ development. The author outlines a range of bottlenecks in the development of restaurant facilities that had emerged before the active phase of COVID-19 started.
Scientific novelty. One of the first attempts was made to analyze the best foreign experience of running the hotel-and-restaurant business in the special conditions of the COVID-19 pandemic, and the dynamics of the development of the restaurant business in Ukraine for 2010–2021 were determined. The article was further improved the ways of strengthening the business conditions in the restaurant industry at the moment, when immediate adaptation is identified.
Practical value. Based on the assessment of the impact of introduced quarantine measures caused by the COVID-19 pandemic on the development of economic entities in the industry, the recommendations over the minimization of their impact through the identification of the main destabilizing factors are offered.

Integrated ecohydrological hydrometric and stable water isotope data of a drought-sensitive mixed land use lowland catchment
Authors: Tetzlaff Doerthe , Smith Aaron , Kleine Lukas , Daempfling Hauke , Freymueller Jonas , Soulsby Chris 
Published: April 2023

Abstract. Data from long-term experimental catchments are the foundation of hydrological sciences and are crucial for benchmarking process understanding, observing trends and natural cycles, and being prerequisites for testing predictive models. Integrated data sets which capture all compartments of our landscapes are particularly important in times of land use and climate change. Here, we present ecohydrological data measured at multiple spatial scales which allow differentiation of “blue” water fluxes (which maintain streamflow generation and groundwater recharge) and “green” water fluxes (which sustain vegetation growth). There are two particular unique aspects to this data set: (a) we measured water stable isotopes in the different landscape compartments (i.e. in precipitation, surface water, soil, groundwater, and plant water), and (b) we conducted this monitoring during the extreme drought of 2018 in central Europe. Stable water isotopes are so useful in hydrology as they provide “fingerprints” of the pathways water took when moving through a catchment. Thus, isotopes allow one to evaluate the dynamic relationships between water storage changes and fluxes, which is fundamental to understanding how catchments respond to hydroclimate
perturbations or abrupt land use conversion. Second, as we provide the data
until 2020, one can also investigate recovery of water stores and fluxes
after extreme droughts. Last but not least, lowland headwaters are often understudied systems despite them providing important ecosystem services
such as groundwater and drinking water provision and management for forestry and agriculture. The data are available at https://doi.org/10.18728/igb-fred-826.3 (Dämpfling, 2023).
