A Study on Measuring Perceived Service Quality Using User-generated Contents (UGC) and on the Effect of Electronic Word-of-Mouth (eWOM) on Customers’ Uncertainty in Service Quality
Authors:   The Korean Production And Operations Management Society, Bang Dohyung
Published: March 2024

This study aimed to measure perceived service quality by analyzing consumer reviews posted on online review platforms. The proposed Perceived Service Quality Index (PSQI) was validated by examining whether its five dimensions could explain overall satisfaction, a non-financial performance indicator for customers. The findings showed that the PSQI was partially valid, with four out of five dimensions significantly explaining the average rating, a proxy for overall satisfaction. To demonstrate the applicability of the PSQI, this study also investigated the impact of electronic word-of-mouth (eWOM) on consumers' uncertainty in perceived service quality using longitudinal PSQI data. The findings indicate curvilinear relationships between eWOM and consumers' uncertainty in the dimensions of assurance, tangibility, and food. Specifically, insufficient information in the eWOM environment may increase uncertainty in these service quality dimensions, while exceeding a certain level of eWOM may decrease uncertainty. Therefore, this study suggests that restaurant managers should continuously monitor and manage the information level distributed through online review platforms to reduce consumer uncertainty in the purchasing decision-making process.

Authors:   The Korean Production And Operations Management Society, Kim Sin Young , Sohn Seong Min , Cho Boo Yun
Published: March 2024

In recent times, companies are facing various external risk factors such as pandemic risks, international political uncertainties, and changes in the global supply chain all at once. To prepare for these adversity, companies are maintaining slack resources as a buffer, enabling them to survive in rapidly changing external environments. This study aims to examine the impact of holding levels of surplus resources, excluding those actually utilized for normal production, on internal capabilities and performance for research and development (R&D). The analysis focuses on small and medium-sized enterprises (SMEs) in the Jeju, which have experienced continuous declines in economic growth since events like the THAAD issue in 2017 and the COVID-19 pandemic. To achieve this, the study categorizes a company's slack resources into Available Slack, Recoverable Slack, and Potential Slack. It then investigates how these slack resources, aligned with the company's perceived risk level, influence R&D performance as mediated by internal capabilities deemed significant by the company. Through this research, the study proposes a direction for companies to appropriately maintain slack resources based on their perceived risk levels. Furthermore, it suggests appropriate support policies and specific directions for support agencies and policy makers to assist companies in achieving their internal capabilities and performance goals for research and development.

Published: March 2024

The article researches the competitiveness of the national economy in conditions of structural changes, the article’s further aim is to define the strengths and weaknesses of the national economy. Based on the carried out analysis of the Global competitiveness index, it is determined that in 2021, in terms of global competitiveness, Ukraine returned to the level of 2013 and took the 54th position among 64 countries. During the period of 2015–2018, the relative stability of Ukraine’s position at the 59th place is observed, in 2019 and 2021 the country demonstrates an increase in rating positions. The analysis of the rating’s components of the ranking indicates that Ukraine’s low position in the global competitiveness ranking in 2021 is due to insufficient economic development. After all, Ukraine occupies the 54th position according to the element «economic indicators». At this, the highest-rated indicator corresponds to the element «business efficiency» (the 50th position in the ranking). It should be noted that it was possible to improve the position regarding the element «infrastructure», according to which Ukraine took the 51st place, while in 2020 it was the 54th position. It is determined that the modern global environment is characterized by a significant level of digitization of all spheres of life activities. The analysis of the country’s competitiveness from the point of view of the use of information and communication technologies is carried out on the basis of the Index of digital competitiveness of countries, which consists of three sub-indices: knowledge; technologies; readiness for the future. It is revealed that for the period 2012–2021, Ukraine had the highest ranking position on the «knowledge» indicator compared to other components and in 2021 took the 37th position, thus improving its ranking compared to the previous period. At the same time, according to the components «technology» and «readiness for the future», the positions in the ranking are approximately the same. The weaknesses and strengths of Ukraine’s competitiveness are highlighted. Among the weaknesses that do not allow Ukraine to take a leading place in the international ranking of digital competitiveness are significant investment risks, an insufficient level of intellectual property protection and the present level of cyber security. Strengths include: providing opportunities to start and develop one’s own business, relatively high Internet speed, e-democracy and high quality of education.

The article analyzes the global trends in the development of small business. The world distribution of enterprises according to the size by countries of the world is studied. An analysis of the development of small and medium-sized businesses by countries of the European Union has been carried out, which has made it possible to identify countries in which small business forms the basis of the formation of the gross domestic product of the State. Enterprises are analyzed in terms of size, indicators of value added, employment and the number of enterprises in the context of sectors of the economy. It is substantiated that the change in value added, employment of the population and the number of enterprises in the context of types of business allows to allocate promising directions for investment in the development of entrepreneurship. The trends of development of small business in different countries of the world have been studied, which has made it possible to allocate the regularities of its development and the relevant factors that contribute to stimulating the development of small enterprises. The directions of reconstruction and development of small businesses in countries after military conflicts have made it possible to identify features and commonalities in terms of the State regulation and support for such changes. On the basis of the carried-out study of the international development of small enterprises, similar directions in the State and regional policy of Ukraine regarding the support and stimulation of small enterprises during the wartime have been formed. Taking into account international experience, the main directions for promoting the development of small business in Ukraine in the post-war period are proposed, which will contribute to the overall socioeconomic growth of the regions and the State as a whole.

Published: March 2024

The governance of the street vendor economy has always been an important part of the social grass-roots governance. To stimulate the economy and ensure employment in the post-COVID-19 pandemic era, the Chinese government's policy towards the street vendor economy has transitioned from prohibition to legalization. This paper traces the three distinct historical phases of China's economic policy concerning street stalls in the 21st century, shedding light on the resistance encountered during the process of legalization. Subsequently, it uses policy comparative analysis to explain the legislative transition and the underlying reasons for these changes in three major Chinese metropolises: Shenzhen, Shanghai, and Beijing. The results show that the city's legislative turning and diversion strategies cannot achieve the expected effect. So the paper proffers suggestions for future policy-making. The suggestions include Person-centered place designation, flexible time, and rights protection policy.

Published: March 2024

Several attempts have been made by researchers for an efficient and cost-effective means of applying irrigation water, since traditional Surface irrigation system is becoming unsustainable due to water shortage. Adoption of most of these systems have failed because sophistication in design and complexity in setup. The use of recycled plastic bottles (PB) is another attempt at achieving a less complex system, yet promoting reuse of spent PB. Experimental Plot was set up in Samaru-Zaria, for a Subsurface irrigation system using recycled PB perforated at the base and connected to network of pipes. Evaluation of the system was carried out to determine the orifice size, orifice depth and the type of fertilizer application with the best agronomic yield parameters in RCBD design with sixteen (16) treatments replicated three (3) times. The results show the treatment with 3mm orifice size buried to 10mm depth with inorganic fertilizer performs best. The use of PB is therefore recommended for use in subsurface system to promote low-cost, less complex yet very effective water saving irrigation system.

Authors: Sani Alhassan Shamsuddeen , Albaba Aliyu Lawal
Published: March 2024

Delafossite copper gallium oxide (CuGaO2) is one of the most important copper-based delafossite materials reported. It has variety of applications that include but are not limited to; photo catalysis, dye-sensitized solar cells. However, due to the wide band gap of this material, it appears very attractive as transparent conductive oxide (TCO). Thus, it is very important and applicable in optoelectronic device technologies. In this paper, the structural, electronic and magnetic properties of vanadium (V) doped delafossite CuGaO2 are investigated using first principle study based on density functional theory (DFT) as implemented in the QUANTUM ESPRESSO simulation package. We used Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation (GGA) exchange-correlation scheme for the undoped and vanadium (V) doped structures. There is no structural transition after the doping. The results indicated that the V doping reduced the band gap of the undoped delafossite CuGaO2 by 0.8 eV. It also contributed more to the conduction band states. However, our results also revealed that the 50 % V doping induced significant changes to the magnetic properties of the undoped CuGaO2. It was found that the undoped CuGaO2 is slightly paramagnetic similar to the same group member CuAlO2, whereas the V doped CuGaO2 system is slightly ferromagnetic. This result is in agreement with previous literature concerning the effect of doping semiconductor material with magnetic metals. Thus, based on our results, V doped CuGaO2 material may be considered as an important candidate for spintronics and other related applications.

Published: March 2024

Wastewater has continued to pose environmental pollution as various industrial and domestic processes effluents are released daily. As man’s activities increase daily, the possibility of facing water scarcity is imminent, coupled with the climate impacts of wastewater on aquatic lives, soil microorganisms, and agricultural produce. Therefore, several innovative developments have considered using carbon-based nanomaterials like carbon quantum dots (CQDs) to treat and recycle wastewater before they are discharged. These CQDs, just like activated carbon, possess adsorptive abilities that can remove heavy metals, solid pollutants, and foul odors from wastewater. However, they are more unique and effective than the traditional adsorbents because they display quantum effects, fluorescence, high stability, tough compatibility, water solubility, little toxicity, easy to produce, and affordable. This review discusses the nature of CQDs, their chemistries, adsorption abilities, limitations, and recommendations for future application and innovation for economical uses.

Authors: Mshelia Simon Stephen , Mbaya Arhyel Yusuf
Published: March 2024

Groundwater is an important source of drinking water in Kano Metropolis, Nigeria. This study aims to assess the suitability of groundwater for drinking using the water quality index (WQI). 960 water samples were collected from 160 sites in the Kano Metropolis and analyzed 9 physicochemical parameters, 9 heavy metals and two groups of microbial parameters using American Public Health Association standard procedures in a laboratory. The values obtained for the various parameters were then compared to the World Health Organization’s (WHO) and Nigerian Standards for Drinking Water Quality (NSDWQ). The overall WQI for each LGA was calculated using Weighted Arithmetic Index guidelines. The results showed that overall WQI is generally unsuitable for drinking with ranged values of borehole water from 47.07 - 149.51 in Dala and Nasarawa respectively while the well water ranged from 94.17 - 251.44 at Tarauni and Kumbotso and spatially represented in map of Kano metropolis. Marginally suitable for drinking were recorded at Dala and some individual wells in well-planned and clean areas (Bompai Quarters, GRAs). The T-Test statistical analysis between borehole and well in Dala, KMC and Nasarawa LGAs showed significant variations at P = < .05 while Fagge, Gwale, Kumbotso, Tarauni and Ungogo LGAs showed no significant differences. The study recommends the need for improved water management strategies, such as desalination and water treatment, to increase access to safe drinking water.

Published: March 2024

Acetaminophen (paracetamol) is a widely used over-the-counter analgesic and antipyretic medication known for its efficacy and safety when administered within recommended doses. However, overdose or prolonged use of acetaminophen can lead to severe hepatotoxicity and nephrotoxicity, posing a significant public health concern. This study aims to investigate the protective effects of vitamin C on acetaminophen-induced hepatotoxicity and nephrotoxicity in male Wistar rats. Six rats were randomly assigned to seven groups, with Group 1 designated as the control. Groups 2, 4, and 6 were given daily single oral doses of 100, 200, and 400 mg/kg of acetaminophen, respectively. Meanwhile, Groups 3, 5, and 7 received daily single oral doses of 100, 200, and 400 mg/kg of acetaminophen, followed by intraperitoneal administration of 100 mg/kg of vitamin C daily, for 14 days. Liver function markers (AST, ALT, total bilirubin, and total protein) and renal function indicators (urea and creatinine levels) were assessed, alongside antioxidant status in liver and kidney tissues through antioxidant assays (SOD, CAT, GSH, and MDA). The results demonstrated the protective influence of vitamin C on liver and kidney tissues, as indicated by the modulation of biochemical markers. These findings suggest that vitamin C may play a pivotal role in alleviating acetaminophen-induced liver and kidney damage across different dosage regimens, potentially serving as a therapeutic intervention for preventing or treating drug-induced organ injuries. Further investigations are essential to elucidate the underlying mechanisms and validate the translational potential of vitamin C as a protective agent against acetaminophen toxicity.

Published: March 2024

Fishes are a source of protein to human and also provide a means of occupation for the people. Fish parasites are of public health importance, reducing fish population and thereby, resulting in loss of protein source and jobs. This study aimed to reveal the presence of various endo-parasites and blood parasites in fish samples collected from Otuogori River using standard techniques. A total of 40 live fish, purchased weekly from a fisherwoman during early morning hours, from December 2022 to January 2023, contingent on availability, were transported immediately to the laboratory for parasitological examination with the sex noted and the standard length measured. Aliquot from teased internal organs and blood sample collected from caudal circulation of each fish were respectively smeared on clean slides and viewed under the microscope. The parasites detected were identified using an identification key. The study revealed that out of 40 Synodontis schall examined, 4 were infected with an overall prevalence of 10%. Females 3(14.29%) were more infected than males 1(5.26%) (p>0.05). Parasites recorded include Trypanosoma spp, Camallanus spp and Anisakid spp; with Trypanosoma spp. (50%) being the most prevalent.  The study result also showed that those with body length range of 9.2cm-14.2cm were infected the most (25%) (p>0.05). Fish samples weighing 55g-105g and those with body length range of 9.2cm-14.2cm had the highest mean intensity. Weight did not significantly affect the prevalence of infestation of the fishes (p>0.05). Fish samples collected from Otuogori River should be properly cooked before eaten to avoid zoonotic infections.

Published: March 2024

Diabetes mellitus (DM) is a prolonged disease with debilitating effect on man. This includes many health problems because the disease is a risk factor for a number of complications. This study employs a multinomial logistic regression model to explore the prevalence of diabetes and identify contributing factors.  Analyzing a diverse range of variables, the study aims to provide in-depth insights into the complex relationships influencing diabetes occurrence. The findings indicated that poor health status contributed more, among other factors, in terms of influencing diabetes. This could be as a result of having other health challenges. Also, women with stroke, high blood pressure, high cholesterol and heart disease were at greater risk of having diabetes compared to those not having. Women who were active had lower risk of having diabetes compared to those who were inactive as physical activities help control bodyweight through increased fat metabolism. Increasing age is often accompanied by a progressive decline in most physiological functions, resulting in increased susceptibility to disease. It was observed in this research that DM was more prevalent in elderly women than women of younger age.

Published: March 2024

The socio-economic spatial structure of Hungary has been dominated by significant territorial differences in the approximately thirty years following the change of regime (and even today). In Hungary the territorial disparities/inequalities are gradually increasing. Before the change of regime the era left a deep mark on both Hungary economy and the attitude of the population, the consequences of which are still felt throughout the country and in Nógrád County as well. The spatial location of the county under consideration - which is remote from an infrastructural point of view - did not help all these spatial effects. In our opinion, many people has become even poorer and few richer than before. Social and economic indicators of Nógrád County (unemployment, income per capita, number of enterprises... etc.) mostly lags behind other counties in Hungary, often lagging behind them to a large extent (Baráthi, 2018). In this study, we try to answer the following question: what are the causes of this and what spatial processes determine the current situation? We present Nógrád County and its northern three districts: Salgótarján, Balassagyarmat and Szécsényi districts, with a special focus on Salgótarján. Based on the results of this research, the main goal is to formulate (based on analysing some theoretical and statistical relationships) and to propose the key factors that can move the county out of its current stagnant or declining situation, especially focusing on its northern part.

Evaluation of local tourism in Iran
Authors: Pourjafargholi Shahrzad
Published: March 2024

This study evaluates local tourism in Iran, focusing on domestic travel. The initial analysis explores the broader role of tourism in Iran's economy and society, alongside an introduction to the country's tourism infrastructures. The study then examines the correlation between local tourism patterns and consumer price and gasoline indices. Surprisingly, the findings challenge the hypothesis, revealing a strong positive correlation (0.84) between the "number of local travels" and the "price index for consumers," as well as a correlation coefficient of 0.68 between "number of local travels" and "gasoline price." However, these correlations do not establish causation. The research identifies additional factors influencing local travel, including lifestyle changes due to migration from villages to cities. Cultural ties and financial considerations also contribute, with a significant percentage (73.4%) choosing to stay with friends and family, reducing travel expenditures. In conclusion, the study suggests a more nuanced understanding of local travel motivations. Future research should explore factors such as intra-country migration, stress indices, environmental pressures in metropolitan areas, marketing strategies, and tourist attraction advertising on local travel trends.

Published: March 2024

Represent Volume Element (RVE) is broadly used by investigators to control the properties of nano-cementitious materials. This paper focuses on analyzing a set of RVE data and proposes parametric equations for determining the compressive and flexural strength characteristics (σc and σf). Primarily, a parametric study is performed with RVE analysis. The essential design parameters are used to fit rational equations. The RVE data are also applied to train artificial neural networks of σc and σf. RVE, neural networks, and rational equations are correlated. Regression equations are validated with the experimental study. SEM, TEM, XRD, and FTIR results are carried out in the microscopic and mechanical analysis for carbon nanofiber cement composites, which can lift their strength, constancy, integrity, and density and reinforce the composite microstructure. Lastly, the Pareto-optimal design results are presented with a multi-objective optimization problem.

Interferon Lambda: An Anonymous Warrior of Host-Microbial Fray in The Pathogenesis of Periodontal Diseases
Authors: Ahmed Muzammil Moin
Published: March 2024

The current body of research focuses primarily on three fundamental groups of interferons: alpha, beta, and gamma interferons. However, little attention is paid to another important group of interferons called lambda interferons (IFN-λs), which have demonstrated activity against periodontal pathogens, particularly viruses. These recently discovered interferon-lambdas provide a striking contrast to the periodontal pathogens, exerting impact both at the capacity of the immune system and the cell, thereby affecting a variety of inflammatory and response pathways. Thus, this review sheds light on role of interferon lambda in the development of periodontal disease and associated activities. In order to collect the information necessary for this review, an exhaustive search of the relevant literature was conducted. The review focused on the structure, regulatory mechanisms, and role of interferon lambda in medical and periodontal infections and diseases. The findings of our review indicated that IFN-λs have an effect on the immunological regulatory mechanisms of the host in relation to viruses, bacteria, fungi, and parasites; nevertheless, their primary role is antiviral, and they have little to no effect on the immune system's ability to fight bacteria.

Authors: Mosca Joseph B. , Merkle Janeth F.
Published: March 2024

Managers and human resource professionals must possess the requisite abilities of generational awareness to effectively match the distinct attributes exhibited by various age cohorts within the overarching objectives of the firm. Organizational leaders must understand the four major age groups that constitute the workforce: the Traditional Generation, the Baby Boomers, Generation X, Generation Y, also known as the Millennials, and Generation Z. A recent study conducted by McKenzie reveals that several factors, namely financial incentives, career advancement opportunities, flexibility in the workplace, and a sense of purpose at work, have a significant impact on employee retention (The Gen Z Equation, 2023). Schroth (2019) suggests that providing appropriate onboarding procedures would result in increased productivity among the Gen Z cohort in the workplace. This study’s primary focus examines Gen Z’s preferences for leadership styles, perceptions regarding organizational culture, and how these affect Gen Z’s learning approaches. The findings are utilized to generate recommendations and strategies for effectively preparing Generation Z for the workforce by implementing strategic orientation and onboarding practices.

Published: March 2024

Background: Reconstructing segmental bone loss defects presents a significant challenge within the field of orthopedics. The purpose of this study is to assess the clinical and radiological results of using the Ilizarov technique for tibia reconstruction following traumatic bone loss. Methods: This study was a prospective study involving 30 patients who experienced tibial bone loss in the diaphysis or metaphysis following trauma. These patients were treated with a ring fixator (Ilizarov) from March 2021 to February 2023. Unfortunately, five patients were lost to follow-up, leaving a cohort of 25 patients who were observed for a duration ranging from 9 to 12 months. Results: The current study involved 25 patients with post-traumatic tibial bone loss. The age range was 14 to 48 years, with a mean age of 28.4±8.8 years. Among the cases, 18 had a moderate defect (72%), which was significantly higher than those with a minor defect (20%) (P ≤ 0.05). Deformity was less than 7° in most cases (96%), while only one case had deformity greater than 7° (4%) (P ≤ 0.05(. Leg length discrepancy was less than 2.5 cm in the majority (96%), with only one case having a 3 cm length discrepancy (4%) (P ≤ 0.05). By the end of the follow-up period, all patients showed perfect union, enabling them to engage in daily activities post-operatively. Conclusion: The success of corticotomy and solid docking relies on well-vascularized bone and soft tissue. Soft tissue compromise at the corticotomy site can hinder healthy tissue regeneration.

BEHCETÜ’L-HADÂİK’TE İLETİŞİM FİİLLERİ
Authors: YILDIZ Şahin
Published: March 2024

Tam adı Behcetü’l Hadâik Fî Mevʿizati’l-Halâik olan Behcetü’l-Hadâik, 41 meclis olarak yazılan dinî-ahlaki bir eserdir. Eski Oğuz Türkçesiyle yazılmış ilk eserlerden biri olması ve Anadolu sahasında yazı dilinin gelişmesine öncülük etmesi dolayısıyla karışık dilli eser özelliği göstermekte olup yazıldığı dönemin ses bilgisi, şekil bilgisi, söz varlığı ve söz dizimi özelliklerini ortaya koymak bakımından oldukça önemlidir. Konusu itibarı ile öğretici olan eser, iletişim fiilleri olarak adlandırılan fiiller açısından zenginlik göstermektedir. İletişim sürecinde vazife gören fiiller olarak açıklanabilecek olan iletişim fiilleri, anlam temelli bir fiil kategorisidir. Çalışmada öncelikle fiiller ve fiil sınıfları üzerinde durulmuştur. Sonrasında iletişim fiilleri ve bununla ilgili yapılan çalışmalar hakkında bilgi verilmiştir. Daha sonra Behcetü’l-Hadâik ile ilgili tanıtıcı mahiyette bilgi verilmiştir. İnceleme bölümünde Beth Levin’in (1993) çalışmasında; mesaj aktarma, anlatma, konuşma tarzı, iletişim aracı, konuşma, gevezelik, söyleme, sızlanma ve tavsiye fiilleri olarak adlandırılan fiillerin Behcetü’l-Hadâik’te kullanımı üzerinde durulmuştur. Bunun sonucunda eserde söyleme ve mesaj aktarma fiillerinin en çok kullanılan; anlatma ve konuşma fiillerinin ise en az kullanılan iletişim fiilleri olduğu sonucuna ulaşılmıştır. Ayrıca Levin’in söyleme fiilleri içinde verdiği tekrarla-, öner- ve beyan et- ile sızlanma fiilleri içinde yer verdiği övün- ve böbürlen- fiillerinin bu gruplarda yer almaması gerektiği belirtilerek araştırmacının tasnifine katkı sağlanmıştır. Çalışmanın Behcetü’l-Hadâik ve iletişim fiilleri çalışmaları açısından yararlı olması umulmaktadır.
Luminescent MOFs Based on Thiazolo[5,4-d]thiazole as a Chemosensor for the Detection of Environmental Contaminants

Luminescent metal-organic frameworks (LMOFs) are considered special candidates for the sensation and detection of particular analytes. Thiazolo[5,4-d]thiazoles (TTZs) are an ideal type of heterocycles for fluorophores with π-bridge moieties demonstrating structure-function characteristics. LMOFs with excellent sensing properties can be constructed by incorporating heterocyclic aromatic thiazolo[5,4-d]thiazole into the framework. This study has elaborated on LMOFs containing thiazolo[5,4-d]thiazole unit for the detection of environmental contaminants, such as toxic anions, aromatic compounds, and heavy metal ions.

Introduction: Universal Newborn Hearing Screening (UNHS) plays an essential role in the early identification of hearing loss in neonates. Risk factors for hearing impairment may include family history, prematurity, and exposure to ototoxic substances. Coronavirus Disease 2019 (COVID-19) might be a significant contributing factor affecting the structures of the inner ear. Objective: To assess the auditory follow-up process of retesting for UNHS before and during the COVID-19 pandemic among neonates from an Outpatient Auditory Health Service (SASA) in the state of Santa Catarina with SUS (Unified Health System) assistance. Methods: A retrospective longitudinal study analyzed data from neonates attended at a SUS Auditory Health Service (SASA) from January 2018 to December 2022. Information related to UNHS and retest outcomes was assessed. Data were analyzed using Microsoft Excel® and MedCalc® Statistical Software version 22.006, utilizing statistical measures and regression analyses to identify factors associated with UNHS failures and retesting. Results: A failure to retest rate of 2.6% in the right ear and 2.2% in the left ear was observed among evaluated neonates. The average age of mothers of neonates who did not pass the test was 33 years, while the overall average was 27 years. Failure to pass the retest and a longer interval between UNHS and retesting were associated with UNHS Initial Retest Default (IRD). There was an increase in dropout rates for UNHS retesting, and the time interval between UNHS and retesting was extended during the pandemic. Conclusion: Several factors, including the interval between tests, mothers' age, and medical conditions, influenced the retest outcomes. The pandemic led to a significant increase in dropout rates and extended time for retesting.
International Laws and The Reality: The Complexity of Corporate Law in Empowering Human Rights

Published: March 2024

Corporations inevitably violate human rights in a variety of ways. As corporations evolved into massive multinational businesses, corporate violence—which is a legacy of colonialism and corporate power—continues to exist today. Corporate players maintain their freedom in pursuing their objectives using convoluted and obscure multinational organizations and supply networks, through the utilization of corporate law principles like the veil of corporate ownership, and also through other practices like tax evasion and lobbying of political bodies. The objective of this article is to explore the legal aspects of the problem of corporate violence, and suggesting reforms to ensure justice for the affected parties. This article uses the doctrinal research method along with the comparative method, focusing on both primary and secondary data. This article makes the case that the issue stems from the structural and systemic flaws in the framework of international law as well as in corporate laws that continually preserve corporate institutions in frustrating the advancement of the cause for human rights.  To effectively enhance the corporate and human rights environment, a framework of hard law, soft law, and non-law reforms and actions is needed.

O presente trabalho tem como objetivo principal a compreensão dos sintomas depressivos na adolescência durante a pandemia COVID-19 numa perspetiva biopsicossocial. Participaram no estudo 826 adolescentes residentes na área geográfica da Câmara Municipal de Famalicão (Portugal). Os resultados revelaram que dos adolescentes em estudo, 30,7 % referiu ter sintomas depressivos, 34,9% sentiu tristeza tão grande que parece não aguentar. Destaca-se que 80,6% sentiu preocupações e 86,2% tem uma perceção positiva da sua saúde. Ter sintomas depressivos está negativamente associado a ter competências socioemocionais, com perceção de bem-estar e, com o conjunto de sintomas físicos e psicológicos. Por outro lado, ter sintomas depressivos está positivamente associado a sentir tristeza tão grande que parece não aguentar e preocupações, ter-se autolesionado e com ter as expectativas futuras afetadas pela COVID-19.
Efficient Global Multi Parameter Calibration for Complex System Models Using Machine-Learning Surrogates

Published: March 2024

In this work, we adress challenges associated with multi parameter calibration of complex system models of high computational expense. We propose to replace the Modelica Model for screening of parameter space by a computational effective Machine-Learning Surrogate, followed by a polishing with a gradient-based optimizer coupled to the Modelica Model. Our results show the superiority of this approach compared to common-used optimization strategies. We can resign on determining initial optimization values while using a small number of Modelica model calls, paving the path towards efficient global optimization. The Machine Learning Surrogate, namely a Physics Enhanced Latent Space Variational Autoencoder (PELS-VAE), is able to capture the impact of most influential parameters on small training sets and delivers sufficiently good starting values to the gradient-based optimizer. In order to make this paper self-contained, we give a sound overview to the necessary theory, namely Global Sensitivity Analysis with Sobol Indices and Variational Autoencoders.
