Authors:   Kenyatta University, Chepkemei Charity
Published: August 2023

In the 21st century, sports events hosting has emerged as a strategic tool for enhancing tourism sectors in various destinations, including Kenya. Despite this, academic research on the viability of sports events hosting as a tourism product in Kenya has been limited. Therefore, this study aims to explore the influence of local community involvement in sports events hosting on tourism development in Uasin Gishu County, with a specific focus on the urban area of Eldoret and its metropolitan regions. The study's theoretical foundation is based on social exchange theory. The research design adopts a cross-sectional approach, with 552 respondents. The sample includes 384 locals, 152 sports tourists, six event managers, eight hotel managers, and two tourism county officials. Data collection involves questionnaires and interview schedules. Quantitative data is analyzed using the Statistical Package for Social Sciences (SPSS), employing descriptive and inferential analyses. Qualitative data undergoes text/content analysis, and its integration with quantitative findings is presented during the discussion. The study's findings reveal a positive and statistically significant relationship between local community involvement in hosting sports events and tourism development (r=0.723, p=0.000). Impressively, local community involvement accounts for 52.2% of the variability in tourism development. Based on these results, the study concludes that local community involvement significantly influences hosting sports events and is associated with regional tourism development. To optimize the benefits derived from hosting sports events, the study recommends adopting a local community-centered approach in managerial, policy, and marketing aspects. By incorporating macro-level involvement through community groups and individual participation, a more equitable distribution of benefits can be achieved, fostering tourism development. Keywords: Local community involvement, Sports events, Hosting, Tourism Development, Uasin Gishu County.

Genetic Analysis of Cone and Seed Characters among Seed Sources of Deodar (Cedrus deodara (Roxb.) G.Don)
Authors: Sharma Rajesh , Bhalaik R.
Published: August 2023

The materials used in this study were obtained from 19 seed sources selected from different geographical areas under the species in the state of Himachal Pradesh. These 19 seed sources were evaluated for variability studies in cone and seed characters. Significant differences (p=0.05) were observed among provenances for cone length, cone diameter and seed weight indicating that a significant amount of genetic variation exists among provenances for these traits. Wide ranges in the means were exhibited for cone weight (79.4-314.40 g), No. of seed (124-230), seed weight (1.5-15.5 g) and No. of scale (120-215). In all cases the standard error were lower than their respective means. All characters were found to have positive and highly significant genetic correlation except cone length and seed weight (0.39). In all the cases genotypic correlations were larger than the phenotypic correlations. The heritability estimates were high for all traits except seed weight (16.26%). The highest values were obtained for cone weight 66.43% followed by cone length 56.73% and cone diameter 53.04%. Cone weight, which recorded highest estimate of heritability also recorded highly significant genetic correlation with all traits. Although heritability estimates in broad sense may give useful indication about the relative value of selection in the materials, heritability along with genetic gain is more useful than the heritability alone in predicting the resultant effect for selecting the best genotypes for a given trait.
Three Main Tools for Luxury Brands to Strengthen Customers Perception of the Brand
Authors: Lin Jingzhi
Published: August 2023

The paper is mainly focusing on examining strategies for firms in the luxury goods market to increase sales. In this paper, the 3 strategies: why logos play an essential role in this industry, why traditional luxury brands began collaborating with fashionable brands and why luxury brands pay high fees to celebrities to engage them as spokespersons, are illustrated. After elaborating on these strategies along with an empirical research and screenshots, the results show that one of the reasons why people are fond of buying luxury products is that logos represent a sense of superiority and may show the owners status; collaboration draws people's attention and increases purchase desire as a large number of people appreciate the combination of luxury and street fashion; star effect leads to many customers want to follow or imitate their idols so they are likely to purchase the clothes or items which their idols have worn.
Research on the Influence of Covid-19 on U.S. Oil Industry Based on Fama-French 5-Factor Model
Authors: Gu Jiaqi
Published: August 2023

This article explores U.S. investors' investment decisions in the oil industry in response to three major events during the COVID-19 pandemic, which are the outbreak of the COVID-19 epidemic, the successful achievement of the Pfizer vaccine, and the end of the COVID-19 epidemic. The data, ranging from January 2019 to November 2022, is processed with Fama-French 5-factor model and the fitting results of the 5-factor model of these four periods of time are derived by multiple linear regression. The significance of each factor of the model will change due to different choices of investors, especially SMB, RMW and CMA. In different periods of the epidemic, investors will not pay attention to the market value, ROE and total asset growth rate of oil companies because of events that are not conducive to the oil industry, such as the US interest rate hike and the Russia-Ukraine war. In addition, investors will also refocus on these indicators when they hear news that is positive for the stock market, such as the successful development of Pfizer's vaccine or a cut in U.S. interest rates. By conducting comparisons and analyses, this article highlights the fluctuations in the stock market within the oil industry. The insights gained from this analysis can prove beneficial for both investors and government officials when formulating policies and making informed decisions.
Economics Teachers' Content Knowledge and Teaching Strategies Used to Teach Economics in Selected South African Schools
Authors: Adu Emmanuel Olusola
Published: August 2023

Economics is a subject offered at the Further Education and Training (FET) section in South Africa, the subject has recorded performance that is not impressive, and the low enrolment and statistics of pass rate are of major concern. Therefore this paper explores the teachers’ content knowledge and strategies used to teach Economics in some selected schools in South Africa. The paper adopts a qualitative approach to phenomenological research design. Purposive sampling techniques were used to select 12 teachers from six schools, two teachers from each school in Buffalo City Municipality in East London, South Africa. A semi-structured interview was used to elicit information from the respondents. The findings among others revealed that Economics is very useful to be a better citizen and to make rational life decisions, the use of the right pedagogy can improve performance, and the content knowledge with adequate on-the-job training will be a match in delivering the content of the subject. It is concluded that a low level of understanding of the basic Economics concepts could be attributed to less professional development training of Economics teachers in content knowledge and pedagogy. It is recommended among others that the Economics teacher have to strike a balance between theory and practice. Teachers should be innovative and improvise by using technological skills, they should move towards the use of technology as a tool to enable learners to become creative, empathetic and high-order thinkers in this digital world.
Solutions with multiple peaks for nonlinear Kirchhoff equations on R^3
Authors: Chen Hong , Hua Qiaoqiao
Published: August 2023

In this paper, we mainly investigate the following nonlinear Kirchhoff equation

\(-\left(\epsilon^2 a+\epsilon b\int_{\mathbb{R}^3}|\nabla u|^2\right)\Delta u +u =Q(x)u^{q-1}\), \(u>0\), \(x\in\mathbb{R}^{3}\),

\(u\to 0\), as \(|x|\to +\infty\),

 

where \(a,b>0\) are constants, \(2<q<6\), and \(\epsilon>0\) is a parameter. Under some suitable assumptions on the function \(Q(x)\), we obtain that the equation above has positive multi-peak solutions concentrating at a critical point of \(Q(x)\) for \(\epsilon>0\) sufficiently small, by using the finite dimensional reduction method. Different from the local Schrödinger problem, here the corresponding limit problem is a system. Moreover, the nonlocal term brings some new difficulties which involve some technical and complicated estimates.
Hastighed, trængsel og CO2 udledning fra personbiler
Authors: Nielsen Thomas Sick
Published: August 2023

Med udgangspunkt i et spørgsmål om betydningen af køkørsel og trængsel for CO2 udledningen fratrafikken gennemgik Vejdirektoratet i 2021 mulighederne for at vurdere effekter af trængsel og hastighedfor energiforbrug og CO2 udledning pr. bilkm.Der er flere typer af emissionsmodeller, der i forskellig grad understøtter en vurdering af betydningen afhastigheder eller trængsel. På det mest overordnede niveau knyttes emissionsfaktorer tilgennemsnitshastigheder eller kombinationer af vejtype, tilladt hastighed og trængselsgrad. På et meredetaljeret niveau kan emissionsfaktorer beregnes på baggrund af informationer om et køretøjs hastighedog accelerationer i løbet af en tur/strækning. Den detaljerede beregning stiller dog store krav tildatagrundlaget, der ofte ikke kan opfyldes i planlægningsundersøgelser.For at belyse betydningen af hastighed og trængsel for CO2 udledningen fra personbiler blev dergennemført en analyse af brændstofforbrug i Connected Cars biler på danske motorvejsstrækninger.Der opstilles en bivariat sammenhæng mellem gennemsnitshastighed og CO2 udledning, hvor hastighedenmå ses som et udtryk for trængselsgraden. Sammenhængen viser, at meget lave gennemsnitshastighedermodsvarer en høj CO2 udledning pr. bilkm, hastigheder mellem 50 og 90 km/t modsvarer en lav udledning,mens højere hastigheder end 90 km/t, og især hastigheder over tilladt hastighed, giver høje CO2udledninger pr. km. Sammenhængen betyder at trængsel på motorvej ofte er med til at reducereudledningen af CO2 pr. bilkm, men at meget høje trængselsgrader også kan være med til at forøgeudledningen pr. km.

Published: August 2023

Introduction:

Studies show that females have a higher prevalence of osteoarthritis, worse symptoms, but lower rates of joint replacement surgery (JRS). The reason for this remains unknown.

Methods:

A database of JRS candidates was created for patients seen in 2019 at an academic center. Demographics, Kellgren-Lawrence grades, symptom duration, visual analogue pain score, Charlson Comorbidity Index, and nonsurgical treatments were collected. Patients who were offered but declined surgery were invited to focus groups. Two independent sample t-tests, Mann-Whitney U tests, and chi-square tests were used for continuous, scored, and categorical variables, respectively, with two-tailed significance <0.05. Qualitative, code-based analysis was performed for the focus groups.

Results:

The cohort included 321 patients (81 shoulder, 59 hip, and 181 knee) including 199 females (62.0%). There were no differences in proportions of females versus males who underwent JRS or in nonsurgical treatments. Female shoulder arthritis patients were older, had a higher visual analogue pain score, and had a higher Charlson Comorbidity Index. In focus groups, males prioritized waiting for technology advancements to return to an active lifestyle, whereas females experienced negative provider interactions, self-advocated for treatment, concerned about pain, and believed that their sex affected their treatment.

Discussion:

We found equal utilization of JRS at our institution. However, female patients experienced unique barriers to surgery.

Authors: Mondal Sarajit Kumar , Banik Sajal Chandra , Rabbi Md. Sanaul
Published: August 2023

The movement of the Fourth Industrial Revolution is touching the manufacturing and processing industries in Bangladesh. The research uses the Fuzzy Analytical Hierarchy Process (Fuzzy-AHP) geometric mean technique, a Multi Criteria Decision Making (MCDM) methodology, to identify, analyze, and prioritize the key obstacles to Industry 4.0 implementation in Bangladesh’s Ready Made Garments (RMG) industries. Another triangular type Fuzzy-AHP extent analysis approach is applied to evaluate the minimum degree of possibilities by using fuzzy appropriateness indices and to determine the weights of assessment criteria. Pairwise comparisons are used to collect 11 experts’ preferences in verbal and numerical terms from different industries. The four main obstacles identified from related review studies are used as input variables in the Fuzzy-AHP methods to measure the intensity level of obstacles. The results have shown that the main four obstacles for Industry 4.0 are “Lack of Top Management Commitment and Owners’ Willingness” (40.6%), “Lack of Ability to Meetup Initial Investment” (30.8%), “Lack of Technical Knowledge and Education” (17.8%), and “Availability of Cheaper Labor” (10.8%). In order to avoid a null weight criterion using Fuzzy-AHP possibility extent, the weight values evaluated using Fuzzy-AHP geometric mean method are considered for decision making. The opinions or ratio scales collected from industry experts are verified with the consistency ratio checking technique.

Bacillus subtilis Miz-8 is isolated from Bekang, a traditional fermented soybean food of Mizoram, India. Here, we report computationally analyzed strain Miz-8 mapped to the annotated genome of the reference strain Bacillus subtilis subsp. natto BEST195. Miz-8 has a circular chromosome and a small plasmid with genome size of 4105264 bp and 5838 bp, respectively. Genome contains the genes responsible for synthesis of biosynthetic metabolites like surfactin, fengycin, bacillibactin, bacilysin, subtilosin A and alpha amylase production. The strain Miz-8 harbored virulence genes identical to the strain BEST195 render themselves harmless for human consumption. However, Strain Miz-8 has one intact prophage region but no integrase protein, making it incapable of lateral transfer of antimicrobials. Antibiotic resistance genes were predicted among which tmrB gene was on perfect hit. Plasmid of strain Miz-8 contains no prophage sequences and antibiotic resistance genes. Furthermore, there were several single nucleotide polymorphisms and 344 insertion-deletion polymorphisms. Bacillus subtilis Miz-8's genomic information unmasks its functional significance on human health.

Published: August 2023

Plant-derived essential oils are natural sources of antimicrobial and pharmaceutical agents besides their broad spectrum of use in the cosmetic, food, and perfume industries. The essential oil from the flowers of P. odorifer was extracted using the hydro distillation method. The major compound from the essential oil was identified by high-resolution mass spectroscopy (HRMS) analysis the identified phytochemicals include p-benzoquinone, 2-phenethyl alcohol, p-cymene, 2-phenethyl methyl either alpha-Terpineol, Psoralen, Isoplumbagin, Genipin, Artemidiol, Pinocembrin, (-)-Glycinol and, Iprobenfos. Two of its major phytochemicals,2-phenethyl methyl ether (PEME) and alpha-terpineol identified through HRMS were procured from Sigma-Aldrich. The antimicrobial properties of the PEME, essential oil, and terpineol was determined using agar well diffusion and micro broth dilution method against four clinically isolated multidrug-resistant (MDR) pathogenic bacteria viz. Staphylococcus aureus, Streptococcus pyogenes, Acinetobacter baumanni, and Pseudomonas aeruginosa. PEME and alpha-terpineol exhibited significant antibacterial activity against all the isolated pathogenic MDR bacteria. No pathological abnormalities were noticed even if it was provided at the highest treatment dose of 800 mg/kg body weight. Further In silico study of molecular interaction analyses have been performed for the proteins Extracellular Adhesion Protein (EAP), Protein A, and Toxic Shock Syndrome Toxin (TSST) of Staphylococcus aureus with the ligand 2-methoxyethyl benzene which shows better interaction with the target. This study validated the robust antibacterial activity of the essential oil of P. odorifer against both gram-positive and negative bacteria. Further, it is validated that the antibacterial activity was mainly because of the presence of two major phytochemicals, PEME and terpineol identified by HRMS analysis.

Published: August 2023

Microbes are harmful as well as beneficial for the human, plants and environment. Plant-microbe interaction array depicts both mutualism and pathogenesis. This dual nature of microbes depends on their surrounding abiotic and biotic factors. Endophytes are plant symbionts, beneficial for plant health. Some microbes are harmful for plants and they also live inside the plants, are called pathogens. The interactions that exist between the endophytic communities have hardly been investigated. The microbes associated with the plants act mostly according to environmental factors. These factors have the ability to alter the nature of microbes from endophytes to pathogens and vice-versa. Thus, by modulating such environmental factors, these microbes can be designed to produce important secondary metabolites or desired products, either within the plants or under laboratory conditions. The plant-microbe interactions have immense research orientation in the near future. The international demand for medicinal plant-based resources has increased due to their augmented exploitation for research and development. Studies of such plants species having parallel phytochemical constituents or microbes producing similar constituents could be an effective way of circumventing this global demand gap. The present review gives a detailed description of the dual behavior that exists in plant endophytes. In addition, it details a state of coherence in their vivid mannerisms and various applications of microbes in different aspects, environmental safety, agriculture, and pollution control.

Medicinal plants have been used for longtime for treatment of many illnesses. Many plants were described in folk heritage to have anti-inflammatory activity to treat digestive diseases. In this study, thirteen plants commonly used by Jordanian folks to treat digestive disorders were investigated to find a connection between their contents and activities and their relationship with their assigned folk use. The ethanolic extracts of the plants were tested for their Total Phenolic Content (TPC), Total Tannin Content (TTC), Total Flavonoid Content (TFC) and their antioxidants activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). In addition to α-Amylase inhibitory activity of the plant extracts was determined. Correlations between TPC, TFC, TTC, protein content with the antioxidant activities (DPPH and ABTS), α-amylase inhibition were determined using Pearson correlation. The phenolic content and flavonoid content showed a high correlation with ABTS activity. The studied plants varied from activation to inhibition of α-Amylase, this may benefit people with hypoglycemia. This diversity of values directs people to which plant to use in case of multi-case disease.

Published: August 2023

Milk is considered as a basic food, highly nutritious, and recommended for everyday consumption during the whole human life. However, due to environmental pollution, milk is not just a source of essential minerals, but potentially can contain heavy metals and trace elements as well which can threaten human health. The study aimed to determine the occurrence of 22 elements: Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, Zn in raw sheep milk collected from areas with different environmental burden in Slovakia. Samples were collected from three farms, one from Orava region (potentially undisturbed area) and two from Spiš region (slightly and heavily disturbed area) during the period of lactation. Analysis of the elements was performed using an inductively coupled plasma-optical emission spectrometry with axial plasma configuration and with auto-sampler SPS-3. Statistical significant differences (P < 0.05) were found in concentrations of following elements: Al, As, Ba, Ca, K, Li, Sr, and Zn. Calcium, potassium, sodium, and magnesium were most represented in samples from all monitored farms. The highest element variation was found in sheep milk samples from the heavily disturbed area. This fact confirmed the quality of monitored areas according to environmental regionalization by The Ministry of the Slovak Republic and the Slovak Environmental Agency. Heavy metals found in the heavily disturbed area do not represent any concerns according to European legislation, except lead, for which the mean concentration represents 0.02 mg/kg. This value was set by EC Regulation no. 1881/2006 and Codex Alimentarius as the level of the permitted limit of concentration of Pb in milk.

2023/19 When does using agency workers lead to a concealed employment relationship between the workers and the user company? (SI)

The Supreme Court of the Republic of Slovenia has issued a judgment concerning the contractual relationship between a worker who had an employment relationship with a de facto employment agency (the ‘agency’) but was continuously working for a port operating company. Given that the ‘agency’ was not registered for the activity of providing labour to a user company and that the agency work was not temporary, the Court found such behaviour constituted a breach of the fundamental requirements arising out of Directive 2008/104/EC on temporary agency work.

2023/20 Employee status of Deliveroo riders: a long-awaited decision (NL)

On 24 March 2023, the Dutch Supreme Court finally ruled on the employment status of Deliveroo riders in the Netherlands. The Supreme Court has followed the earlier ruling of the Amsterdam Court of Appeal and ruled that Deliveroo riders qualify as employees (instead of self-employed workers). Even though the Advocate General of the Supreme Court advised the Court to develop new criteria for determining whether a worker qualifies as an employee or not, the Supreme Court applied roughly the same criteria as it had done in the past. The Supreme Court considered that developing new general rules for determining whether a worker is self-employed or employed is up to the national and European legislators.
MORGen: an Algorithm to Compute Spreading Centre and Transform Geometries from Simple Initial Plate Boundaries and Euler Rotations
Authors:   Utrecht University, van der Linden Thomas , van Hinsbergen Douwe
Published: August 2023

The age structure of the global ocean floor is a key feature in paleogeographic reconstructions, which in turn forms the quantitative basis for Earth System Science. However, much of the ocean floor in paleogeographic reconstructions has been lost to subduction. The age structure of such lost ocean floor is constructed from the reconstructions of adjacent continents, using the relative rotations, around Euler poles to predict the geometry of spreading centres and transform faults. Building such mid-ocean ridge features in paleogeographic reconstructions is laborious, as it requires redrawing of ridge-transform systems upon every Euler pole shift in the model. In this paper, we present the Mid-Ocean Ridge Generator (MORGen) algorithm, based on pyGPlates. MORGen reduces the laborious task by automating the drawing of mid-ocean ridge geometries from geometrically simple plate boundary input assuming ridge-perpendicular spreading and adjusts ridge geometries in a simplest-scenario fashion by gradually adjusting ridge orientation and transform fault length upon Euler pole shifts, inspired by observations from the modern sea floor. The code takes as input curved line features, representing approximate divergent plate boundaries, and a set of Euler poles. These are then converted into spreading centre-transform geometries. Upon Euler pole shifts, the geometries are adjusted to fit the set of small circles and great circles dictated by the new Euler pole. For studies of paleo-environment and paleo-oceanography MORGen can be used in combination with other algorithms for full reconstructions of ocean floors, including their age, bathymetry, and roughness. For in-situ preserved ocean floor, the paleo-age distribution can be reconstructed directly in high resolution from geophysical and geological data from the modern ocean floor and MORGen would not normally be the option of choice. In cases where models contain ocean floor that has now been subducted, MORGen straightforwardly facilitates mid-ocean ridge geometry reconstruction. To illustrate how well the MORGen algorithm reproduces real ocean floor age structure, we show a synthetic ridge evolution for the South Atlantic and Southern Oceans and compare this to geophysically constrained ocean floor geometry. In addition, we show examples of use cases where direct (re)construction of mid ocean ridges is not possible: now-subducted ocean basins in the Mediterranean region and an ocean in a future supercontinent scenario.

Tujuan dari studi penelitian ini adalah untuk mengetahui potensi energi angin di Kota Banda Aceh serta merencanakan spesifikasi turbin angin yang sesuai berdasarkan hasil perhitungan.Permintaan akan energi khususnya energi listrik di Indonesia semakin tinggi dan menjadi bagian tak terpisahkan dari kebutuhan hidup masyarakat maupun sektor industri. Bahan bakar fosil yang digunakan sebagai bahan utama untuk menghasilkan listrik, ketersediannya semakin terbatas, belum lagi polusi yang dihasilkan oleh proses konversi dari bahan bakar fosil tersebut. Pengembangan sumber energi alternatif makin digalakkan melalui kebijakan pemerintah untuk mendorong dan menfasilitasi pemanfaatan sumber-sumber energi tersebut misalnya hydro, matahari, panas bumi, biomassa dan juga angin. Dari latar belakang dan rumusan masalah diatas maka dilakukan studi penelitian yang difokuskan kepada sumber energi angin.Hasil perhitungan didapat untuk diameter rotor 8 meter, daya output yang paling besar terlihat pada Bulan Agustus yaitu 18,71 kW dan yang terendah pada Bulan Februari yaitu 0,95 kW. Daya output rata-rata adalah 7,18 kW. Dari hasil perhitungan jelas terlihat bahwa daya output sangat tergantung pada kecepatan angin dan luas area sapuan rotor (rotor swept area).  Spesifikasi turbin yang direncanakan adalah turbin angin sumbu horizontal dengan jumlah sudu 3 dan daya output 10 kW. Koefisien rotor adalah 0,42 dengan diameter rotor 8 meter.
