Published: September 2023

Introduction: Millions of women globally experience menstruation every month. It is a normal biological process.Inadequate menstrual management has long been a major health issue in low- and middle-income nations, but ithas only recently become a major public health concern. Females may manage menstruation with non-absorbent,unhygienic, and uncomfortable materials due to a lack of awareness, an unfavorable sociocultural environment,logistical and financial barriers, and a lack of a proper support system. Hence this study was undertaken to assessthe knowledge and attitude among medical students.Methodology: This study was conducted among 200 undergraduate female medical students , who were willingto participate in the study. Informed consent was taken and the oral questionnaire which consisted of sociodemographic data and questions regarding knowledge, attitude and practice was distributed. Descriptive analysiswas done by calculating the percentage.Results: 91% of the students were aware of the menstrual cup. A total of 168(84%) students said menstrual cupto be a safe device. A total of 171 (85.5%) students knew that the menstrual cup could be used among virgins.whereas 29 (14.5%) students were of the opinion that it cannot be used by virgins. 84(42%) of students had no ideaabout its associated with TSS (Toxic shock syndrome). 73(36.5%) of students knew that it is not associated withTSS.143(71.5%) said it can’t be used during postpartum and 112(56%) knew that it is used during bathing andswimming.134(67%) students knew that it can’t be used as contraceptives and 88(44%) told it won’t cause ruptureof hymen.Finally in this study we came to know that none of them are using menstrual cup because majority ofthem said that they had fear of using 92(46%) and 51(25.5%) of them said they don’t have adequate knowledge.Conclusion :In this study all the students used sanitary pads, owing to its popularity and promotion. Therewas lack of awareness about the cup and there exists a huge gap between the knowledge and willingness of thestudents to accept the menstrual cup. So, we conclude that menstrual cup needs promotion in India because itis cost effective, eco-friendly and reusable. So, we boost the adoption rate of menstrual cups, youth should betargeted, who are more open to the idea of environment-friendly products.

Soproper screening of all patients of tuberculosis for diabetes mellitus is necessary for early diagnosis and treatment.Health education and counselling are equally important
Mariánské poutní místo Sepekov a prameny k zázračným událostem a jeho historii
Authors: Kuchařová Hedvika
Published: September 2023

The subject of this paper is an analysis of manuscript and printed sources on the pilgrimage site of Sepekov (Písek district). These comprise texts written between the 1730s and the 1780s. Thematically, these are mostly books of miracles, which were intended to record miraculous events in writing and (in the case of printed sources) to spread awareness of the existence and importance of the pilgrimage site; however, they also contain information on the history of Marian devotion in Sepekov. Most of these works are anonymous; nevertheless, since the books of miracles were mostly written by parish priests, the identification of the likely authors is based on the analysis of the staffing of the church administration in Sepekov by the Strahov Premonstratensians. An interesting aspect is the intermingling of the works of the Premonstratensians and the local layman, teacher and sacristan František Strejček.

Five different fabrics; Cotton, Poly-cotton blend, Light Neoprene, Polyester, Neoprene were purchased from Gashua market and 500 fabric face masks were produced. Three parameters; air permeability, elongation, and tensile strength were used to determine its fabric functional and quality properties. Laboratory tests as well as structured questionnaires were used as instruments for data collection. Polyester has the highest tensile strength of 1214.02N, followed by poly-cotton blends and the lowest being cotton 714.80N. Neoprene has the highest elongation of 78.81%, followed by light Neoprene and the least is 20.29%. Cotton has the highest air permeability of 118.36 ft3/ft2min, followed by Neoprene and light Neoprene respectively; the lowest is poly cotton blends. The cotton face mask has the best characteristics in terms of ease of breathability, can easily be washed and does not fog on the glass of the wearer. Poly-cotton blends face masks follow cotton in all the three characteristics stated above and it was adjudged to be the best in fitness for wearing. Polyester face mask produces the lowest result in breathability and fog production in the glasses.

Electronic form of transactions: Issues of legal regulation
Authors: Shugaev R. I.
Published: September 2023

This paper analyzes the form of transactions made with the use of electronic and other technical means (electronic form). The research aims to determine the essential features and develop an optimal model of regulation of electronic transactions form, considering foreign experience, theoretical advances, and judicial practice. The relevance of the study is explained by the increasing number of e-transactions which require adequate legal regulation and law enforcement practice. The author consecutively describes internationally recognized regulatory principles of electronic transactions form (non-discrimination, technological neutrality, functional equivalence) and their implementation in Russian and foreign law. In addition, the author analyzes the issue of the correlation between the written and electronic forms, considers and rejects arguments in favor of singling out electronic methods of will formation as an independent (sui generis) form of transactions. Considering the current Russian judicial practice and foreign experience, the study determines the criteria and methods of reliable determination of a person effecting an electronic transaction. On the grounds of dogmatic and political arguments, the overly formalistic idea that the use of a qualified electronic signature is the only way of such identification is rejected. The author also formulates an optimal interpretation of the Russian Civil Code requirement on the reproducibility of the electronic transaction content on a tangible medium unchanged. Based on the results of the study, practical recommendations are described to help judges make fair and reasoned decisions in specific situations interpreting the provisions of the Russian Civil Code on the electronic form of transactions.

Navigating the challenges of lecturers’ retention in South Africa: Perspective of a rurally located university
Authors: Mahoko Neo
Published: September 2023

Most university students do not get the opportunity to graduate in the presence of their first-year lecturers because those lecturers may have moved to another university. The identified challenge is that universities, notably those located rurally, cannot retain their lecturers for extended periods. Therefore, the study explores the challenges hindering lecturers’ retention in a rurally located South African University. The qualitative study included 14 participants from the selected university, using purposive and convenience sampling methods. A semi-structured interview was used to elicit information from the participants within the principles of Participatory case study design. Braun and Clarke’s six-step thematic analysis method was adopted to analyse the data thematically. The study found that salaries and benefits, along with physical working conditions, are institutional challenges to retaining lecturers, while factors such as lack of stability and loss of interest at work are internal and external challenges affecting lecturers’ retention in their workplaces. The study concluded that institutional challenges are within the control of university administration and addressing them can help retain more lecturers. On the other hand, internal and external challenges, such as lack of stability and loss of interest at work, are more complex and require individual attention from the lecturers themselves.

The demographics of young exoplanets can shed light on their formation and evolution processes. Exoplanet properties are derived from the properties of their host stars. As such, it is important to accurately characterize the host stars since any systematic biases in their derivation can negatively impact the derivation of planetary properties. Here we present a uniform catalog of photometrically derived stellar effective temperatures, luminosities, radii, and masses for 4865 young (<1 Gyr) stars in 31 nearby clusters and moving groups within 200 pc. We compared our photometrically derived properties to a subset of those derived from spectra and found them to be in good agreement. We also investigated the effect of stellar properties on the detection efficiency of transiting short-period young planets with TESS as calculated in Fernandes et al. (2022) and found an overall increase in the detection efficiency when the new photometrically derived properties were taken into account. Most notably, there is a 1.5 × increase in the detection efficiencies for sub-Neptunes/Neptunes (1.8–6 R
⊕) implying that, for our sample of young stars, better characterization of host star properties can lead to the recovery of more small transiting planets. Our homogeneously derived catalog of updated stellar properties, along with a larger unbiased stellar sample and more detections of young planets, will be a crucial input to the accurate estimation of the occurrence rates of young short-period planets.

We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs—HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observations of the Sun from four different instruments, we are able to gain insight into the radial velocity precision and accuracy delivered by each of these instruments and isolate instrumental systematics that differ from true astrophysical signals. With solar observations, we can completely characterize the expected Doppler shift contributed by orbiting Solar System bodies and remove them. This results in a data set with measured velocity variations that purely trace flows on the solar surface. Direct comparisons of the radial velocities measured by each instrument show remarkable agreement with residual intraday scatter of only 15–30 cm s−1. This shows that current ultra-stabilized instruments have broken through to a new level of measurement precision that reveals stellar variability with high fidelity and detail. We end by discussing how radial velocities from different instruments can be combined to provide powerful leverage for testing techniques to mitigate stellar signals.

We report the observations of FRB 20220912A using the Five-hundred-meter Aperture Spherical radio Telescope. We conducted 17 observations totaling 8.67 hr and detected a total of 1076 bursts with an event rate up to 390 hr−1. The cumulative energy distribution can be well described using a broken power-law function with the lower- and higher-energy slopes of −0.38 ± 0.02 and −2.07 ± 0.07, respectively. We also report the L-band (1–1.5 GHz) spectral index of the synthetic spectrum of FRB 20220912A bursts, which is −2.6 ± 0.21. The average rotation measure value of the bursts from FRB 20220912A is −0.08 ± 5.39 rad m−2, close to 0 rad m−2 and was relatively stable over 2 months. Most bursts have nearly 100% linear polarization. About 45% of the bursts have circular polarization with Signal-to-Noise ratio > 3, and the highest circular polarization degree can reach 70%. Our observations suggest that FRB 20220912A is located in a relatively clean local environment with complex circular polarization characteristics. These various behaviors imply that the mechanism of circular polarization of FRBs likely originates from an intrinsic radiation mechanism, such as coherent curvature radiation or inverse Compton scattering inside the magnetosphere of the FRB engine source (e.g., a magnetar).
Productivity and impact of the Unisinos’ Postgraduate Program in Biology and the consequences of its interruption for Brazilian science
Authors: Boll Piter Kehoma , Krüger Lucas
Published: September 2023

On 22 July 2022, the Universidade do Vale do Rio dos Sinos (Unisinos), a private institution and community university in southern Brazil, announced the interruption of 12 of its postgraduate programmes, including the Postgraduate Program of Biology (PPG Biologia), whose professors founded the journal, Neotropical Biology and Conservation. We conducted a bibliometric analysis of papers published by PPG Biologia in the past 20 years to assess its impact on biological research at a national level. The number of publications and citations increased constantly over the years, with publications growing exponentially. Although most collaborations with other research programmes occurred inside Brazil, a significant number of studies were co-authored by researchers from other countries from at least four continents. The main research lines focused on biological sciences, ecology, sociology, education, environmental sciences and genetics. Despite being affected by the decrease in research funding and the reduction of personnel, PPG Biologia kept its high impact score according to the national evaluation, above that of most programmes in private universities and similar to public ones. With a team of renowned researchers working on different and sometimes unique research lines, the interruption of PPG Biologia will harm the progress of biological research and conservation across the Neotropical realm.
La recherche en protection de l’enfance à l’épreuve des données personnelles

Published: September 2023

Enquêter en protection de l’enfance, c’est produire de la connaissance tout en assurant le droit au respect de la vie privée des principaux concernés. Aujourd’hui, les règles relatives à la protection de données à caractère personnel, au niveau national comme européen, rendent particulièrement difficile la conciliation des droits des parents et des droits reconnus aux enfants et exercés, sauf exception, par les titulaires de l’autorité parentale, avec la production de connaissances fiables et scientifiquement établies. L’étude des tensions juridiques à l’œuvre lorsqu’il s’agit de développer la recherche sur l’enfance fait l’objet de peu d’écrits et il n’existe pas encore de doctrine partagée sur l’interprétation des textes en vigueur. Cet article propose une première réflexion sur ce sujet.
Influence of Anxiety and Depression on Opioid Use After Cervical Spine Fusion: An Analysis of a National Claims Database
Authors: Makanji Heeren , Solomito Matthew J. , Kostyun Regina , Esmende Sean
Published: September 2023

Patients with spine pathology demonstrate an above average rate of active psychiatric disorders, which can influence their recovery. This study was designed to understand how mental health diagnoses (ie, anxiety and depression) influence a patient's postoperative need for opioids after a single level cervical spine fusion. The PearlDiver database was used to identify patients. Patients were placed into one of four groups: those with a diagnosis of depression, those with a diagnosis of anxiety, those with a diagnosis of both anxiety and depression, and a control group. Chi-square tests were used to assess differences in the number of patients filling initial and additional opioid prescriptions for up to 90 days after their fusion. A total of 168,967 patients who underwent an elective cervical spine fusion in the United States between 2010 and 2021 were included in this study. The control group filled significantly more opioid prescriptions within the first 90 days after their cervical fusion (
P
<.001). There was no difference among the study groups regarding the need to fill additional opioid prescriptions. Patients with a diagnosis of depression and/or anxiety may present as complex patients; however, results suggest they do not need additional opioids for pain control after a single level cervical spine fusion.

A modified optimal control for the mathematical model of dengue virus with vaccination
Authors: Pongsumpun Puntipa , Lamwong Jiraporn , Tang I-Ming , Pongsumpun Puntani
Published: September 2023

The dengue viruses (of which there are four strains) are the causes of three illnesses of increasing severity; dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Recently, dengue fever has reached epidemic proportion in several countries. Strategies or preventative methods have to be developed to combat these epidemics. This can be done by development of vaccines or by preventing the transmission of the virus. The latter approach could involve the use of mosquito nets or insecticide spraying. To determine which strategy would work, we test the strategy using mathematical modeling to simulate the effects of the strategy on the dynamics of the transmission. We have chosen the Susceptible-Exposed-Infected-Recovered (SEIR) model and the SusceptibleExposed-Infected (SEI) model to describe the human and mosquito populations, repectively. We use the Pontryagin's maximum principle to find the optimal control conditions. A sensitivity analysis revealed that the transmission rate $ ({\gamma }_{h}, {\gamma }_{v}) $, the birth rate of human population ($ {\mu }_{h} $), the constant recruitment rate of the vector population ($ A $) and the total human population ($ {N}_{h} $) are the most influential factors affecting the disease transmission. Numerical simulations show that the optimal controlled infective responses, when implemented, cause the convergence to zero to be faster than that in uncontrolled cases.
Les commémorations du centenaire de 1927 à Vienne
Authors: Picard Sophie
Published: September 2023

Beethoven, un compositeur vénéré par l’humanité tout entière ? Ce paradigme universaliste, repris à l’envi lors de la commémoration du 250e anniversaire du compositeur, s’est en réalité imposé tardivement dans l’histoire de sa réception. Il constitue la marque durable de la célébration du centenaire de Beethoven à Vienne en 1927. L’article reconstruit les stratégies médiatiques et discursives mises en œuvre pour instituer une figure de classique universel qui est au monde ce que les classiques nationaux sont aux nations. Il montre comment le paradigme universaliste déployé en 1927 autour de la figure de Beethoven déstabilise, au moins pour un temps, la réception nationale et nationaliste du compositeur en Autriche et en Allemagne.
Hofmannsthal et la mythification de Beethoven en poète, titan et prophète européen
Authors: Giboux Audrey
Published: September 2023

Hofmannsthal, tout au long de sa carrière, se réfère constamment à Beethoven, dont l’œuvre lui semble toujours éminemment vivante et moderne à une époque qui, à ses yeux, manque cruellement d’une grande figure européenne unificatrice. Dans les discours qu’il lui consacre en 1920 pour son cent-cinquantième anniversaire, c’est notamment la situation de Beethoven à Vienne qui est interrogée. L’éloge du compositeur, dans le contexte troublé des premières décennies du xxe siècle, répond ainsi à des enjeux pluriels : consacré par Hofmannsthal en tant que poète, Beethoven devient sous sa plume, dans la lignée de l’imagerie titanesque qui s’est développée tout au long du xixe siècle et au gré d’un imaginaire tour à tour littéraire, politique, mythologique ou biblique, un des plus grands mythes de l’Europe et l’une des figures tutélaires majeures de son engagement européiste.
Maritime Transformable Area Systems
Authors: Sredic Vejn
Published: September 2023

Transformable area systems (TASs) offer new possibilities for sustainable factory planning and development, notably as regards maritime structures. This is of relevance to factories of the future and could constitute a major influence in future factory planning and operation (i.e., the way in which factories are planned, implemented, transformed, relocated, used, and managed). Floating pontoon islands with solar systems already exist, and so much more is possible with similar but more complex structures. This article explains the basics of the TAS concept, assesses its potential, and discusses the future possibilities. It concludes that lack of knowledge and awareness about TASs and their potential is holding back their application in practice. Omnipresent short-term thinking and short-term profit expectations are further hurdles that are limiting the further development of TASs at present. TASs could nevertheless contribute to the improved functioning, sustainability, and future viability of factories, other structures, and their development.

Published: September 2023

O crescimento da formação em administração traz consigo a necessidade de decolonização no campo, tendo em vista a hegemonia na produção de conhecimento dos países do norte global. Nesta pesquisa buscou-se analisar as representações de discentes do curso de Administração, da figura de administrador brasileiro e os arquétipos apresentados na nova diretriz curricular nacional do curso - DCN. Para tanto, foi realizada uma pesquisa empírica por meio de desenhos feitos por dezesseis discentes do curso de graduação em Administração de duas IFES do Estado do RJ. Com o auxílio da semiótica Greimasiana situacional foi possível perceber que há um distanciamento entre as percepções dos discentes e os arquétipos apresentados na DCN e que a adoção acrítica desta tende a corroborar para com o quadro de americanização no ensino em Administração e com a colonialidade do saber.
Role of Portable Charger in Electric Vehicle
Authors: Borgohain Achyutish , Choudhury Pradyumna Kumar
Published: September 2023

Emergence of rapid industrialization with recent development in technology has led to increasing trend of fossil fuel consumption that has been a major cause of global warming and climate change and has become a severe threat to global health. The global transportation sector contributing to a huge percentage of CO2 emission, thus require some sustainable and effective fuel alternatives. Electric Vehicles (EVs) serve to minimize reliance on fossil fuels in the process of driving but still depend on these fuels indirectly in the EV charging process from the conventional grid. Thus, they cannot be considered greener completely unless they are charged from Renewable Energy Sources (RES). This study presents the state-of-art overview, status of EV charging technologies and comparison between various EV charging facilities. The paper reviews the role of EV portable chargers to reduce dependence on electricity grid and help to cope with technical challenges related to EV including driving-range anxiety, long charging time and lack of charging facilities. The study focuses on the status of latest research and development in the field of EV portable chargers throughout the world and comparative analysis between four commercially available EV portable chargers is performed to introduce a scope for improvement and development of efficient, reliable, eco-friendly and user convenient EV portable chargers.

Published: September 2023

The dry turning was done on the high tensile low alloy steel. The Indoloy carbide tool was used. The input parameters were speed, feed, and depth of cut (DOC, d). The chip reduction coefficient (CRC) and von Mises stress (VMS) were the output responses. Universal tensile testing was done to find out the strength coefficient (K) and strain hardening exponent (n). "K" and "n" were incorporated to obtain the von Mises stress (VMS). The experiments were performed following the L9 array (Taguchi). The analysis of variance (ANOVA) was done for the CRC, with the lower the better condition. The ANOVA was done for VMS with the lower-better condition. The ANOVA was done by developing a MATLAB program. The feed contributed strongly to both the CRC (80.1381% contribution) and VMS (33.1490% contribution) minimizations. A Taguchi-Fuzzy inference system (FIS) simulation was done (MATLAB software) to select optimal parameters. CRC and VMS were the inputs, and MPCI (multi performance characteristic index) was the output for the simulation. The simulation was done based on the rules. The optimal parameters were found at moderate speed, high feed, and moderate DOC. Machining chips were collected for different experimental conditions. The chip form study was done.

Despite the benefits of BIM, some challenges to implementing it have appeared due to traditional project management, especially in the construction of complex projects. This article presents the challenges to applying ISO 19650:2018 Parts 1 and 2 in public hospital projects in Peru. These challenges were identified through 28 interviews with owners, designers, contractors, suppliers, operators, and final users (doctors and nurses) and complemented by a literature review. The identified challenges were divided into the budget, legal framework, organizational culture, and personnel. The results suggest that the adversities identified in the four groups should be overcome to implement BIM according to the ISO 19650 guidelines. Therefore, recommendations are presented to facilitate the ISO 19650 implementation in public hospital projects.

In this study, we investigated the impact of high-energy milling on the structural and dielectric properties of Pb[Zr(1-x)Tix ]O3 [PZT] ceramics synthesized using the solid-state reaction process. The sample was milled for 2, 4 & 6 hours using a high-energy ball milling machine. The unit cell structure for all of the samples was observed to be monoclinic, according to x-ray diffraction measurements (space group: C1m1). A significant reduction in crystallite size was observed, from 132 nm to 46 nm after 6 hours of milling. The dielectric study indicated a classical ferroelectric type behaviour for the un-milled sample and diffused phase transition for all milled samples. However dielectric constant dropped from 940 to 487 after 6 hours of milling.

Published: September 2023

Rockets are the non-air breathing engines used for space exploration carrying both fuel and oxidizer and increasing the cost missions. So, to reduce the cost of space exploration, research on air breathing engines known as Scramjet engines is focused. Scramjet engine achieves hypersonic speeds by the efficient design of intake. The intake provides high pressurized flow to the combustion chamber by compressing free stream flow using shock waves generated from ramp and cowl. Thus, the strength of shock waves generated in the intake due to ramps and cowl will define the efficiency of intake. The efficient design of hypersonic intake will depend on the ramp angles and quantity of ramps, Osawtitsch and Kantrowitz criteria. This paper deals the design of hypersonic intake based on performance parameters like Total Pressure Ratio, Kinetic Energy efficiency and Static Pressure ratio using a python code for various Mach numbers 5, 6, 7 and 8. The proposed method designs mixed compression double ramp intake using oblique shock theory. The novelty of the present work is to understand the geometrical changes attained as per change in operating conditions of the engine. The hypersonic intake designed for Mach 5 is validated with CFD results and compared with analytical results using python code.

Published: September 2023

In cold forging processes, diamond-like carbon (DLC) coatings have become established as a wear protection for forging dies, featuring high hardness and advantageous friction properties. This counteracts the particular critical abrasive tool wear and increases tool life. A major disadvantage of DLC coatings is their low thermal stability. In this study, the influence of metallic elements (niobium, tungsten and chromium) in the treatment atmosphere of the coating process is investigated with the aim of increasing the temperature resistance of the DLC coating and enabling its application as a wear-protection measure for hot forging dies. Preliminary studies were carried out to investigate the influence of different treatment atmospheres on wear-reducing properties such as high hardness and coating adhesion depending on prior nitriding processes. The most promising metal-doped DLC coating, with 30 % tungsten in the treatment atmosphere, was used in serial forging tests. At a blank temperature of 1,200 °C and a moderate count of 100 forging cycles, wear was reduced by up to 60 % compared to the nitrided reference tool.
Structure, Microstructure, and Dielectric Properties of Bi0.5(Na0.78K0.22)0.5TiO3 Lead-Free Ceramic

Published: September 2023

In this article, the structural, microstructural, and dielectric properties of Lead- free perovskite ceramic Bi0.5(Na0.78K0.22)0.5TiO3 [BNKT] have been reported. The material was synthesized through the solid-state reaction method. The compound formed is found to have a hexagonal structure, confirmed by XRD analysis of the sample. The microstructural analysis of the compound revealed the polycrystalline nature of the ceramic having quasi-cubic grain morphology with distinct grain boundaries. From the dielectric study, it was found that the dielectric constant increases with temperature and attained maximum value at temperature Tc = 335° C, after which it decreased. The frequency independence of transition temperature (Tc) suggested the classic ferroelectric behaviour of the compound. The broad dielectric peak around transition temperature confirms the relaxor behaviour of the compound as well as diffused phase transition at Tc. The value of the relative permittivity and loss tangent at ambient temperature for 1kHz frequency is 627 and 0.223 respectively. The synthesized material can be utilized for the fabrication of capacitors and energy storage applications.

Published: September 2023

The building industry is strongly reliant on materials, which account for 55%-60% of its expenses. However, due to outdated and time-consuming approaches, inadequate inventory management prevails. This is where developing technologies such as Deep Learning (DL) might help uncover solutions. Surprisingly, very little scientific research on DL has been conducted for this purpose. As a result, this study looks into the prospect of automating construction warehouse management by employing CNN for object detection and counting. During the initial investigation, 23 studies out of 26 used Convolutional Neural Networks (CNN) for image processing and object detection. Secondly, a model was developed and compared its accuracy to that of human counting and discovered that the model outperformed people. Industry professionals were interviewed to discuss the findings. Industry professionals highlighted the advantages and disadvantages of using such an automated system in construction warehouses. In conclusion, this study shows that the CNN base model outperforms people in counting materials, and the proposed automated inventory management system has significant industry potential.
Influence of state bus services on school attendance in under-privileged remote areas: reflections from a case analysis in estate areas of Haputale, Sri Lanka

Published: September 2023

Free education for all in Sri Lanka has enabled significant improvements in educational performance and living standards. However, there are still some issues unresolved; one being the difficulties in accessing education facilities in the townships, owing to mobility constraints. Students residing in plantation areas, for instance, become inconvenienced when public bus services are absent or unreliable.The present research quantitatively examined the significance of SLTB bus service availability, inter-alia, in determining the school attendance rate of students residing in remote estate areas. The Haputale Education Division was examined as a case study. Results indicated that, among factors that could significantly affect the level of school attendance of estate children, the availability of SLTB service on estate routes would be very crucial; a significant increase in attendance being realisable if SLTB’s scheduled school bus trips operated with greater reliability. The importance of affordable mobility services for school attendance in remote areas, is thus examined.The study enabled inference that the policy priority should be assigned to further strengthen and expand bus services. This intervention is likely to be more beneficial than focusing on other apparently influential determinants. However, the generalisability of these findings to other estate areas and geographically remote localities of the country needs to be confirmed through further research.

Published: September 2023

Consumers and suppliers demand transparency in the textile and apparel industry due to increasing complexity, volatility, and competition in the global market. While research communities acknowledge the scarcity of publications in this domain, the number of related papers has surged by 122%. Nonetheless, existing reviews have primarily refrained from offering a comprehensive exploration of transparency within the broader context of textile and apparel supply chains. Consequently, a gap in systematic reviews focusing on transparency within this domain is evident. To fill this gap, our study aims to synthesise existing research on transparency in apparel and textile supply chains. To this end, we have structured our study into four research clusters derived from author-generated keywords in a carefully curated Scopus dataset. Furthermore, our study explores how transparency has evolved in textile and apparel supply chains, supported by these four clusters, which cover the following themes: 1) Sustainable approaches for transparency, 2) Supply chain perspective in transparency, 3) Implementing traceability for transparency and 4) Information transparency. Considering the insights gleaned from this comprehensive review, our study offers valuable insights and delineates potential directions for future research endeavours. These avenues for exploration can improve transparency in textile and apparel supply chains towards greater advancement and scholarly innovation.
