Relationship between Women on Board Directors and Economic Value Added: Evidence from Latin American Companies
Authors: Arango-Home Maria Camila , González-Ruiz Juan David , Valencia-Arias Alejandro
Published: September 2023

This study aims to evaluate the relationship between the presence of women on boards of directors and the generation of economic value added (EVA®). For the empirical analysis, a panel data model with random effects is used, encompassing 202 Latin American companies between 2019 and 2021. The results obtained show that having women on boards of directors has a non-significant positive effect on EVA®, which diminishes as women’s participation on the board increases. Theory suggests that more diverse boards of directors exercise better control, leading to improved financial results. However, the diversity of members has also been associated with longer decision-making processes that generate inefficiencies and increase costs. This contribution adds to the existing literature by exploring under-studied variables in the region and expanding knowledge on this topic in the Latin American context.
Development of Energy-Saving Battery Pre-Cooling System for Electric Vehicles
Authors: Chang Tong-Bou , Xiao Yi-Zong , Liu You-Fan
Published: September 2023

The performance, lifetime, and safety of electric vehicle batteries are strongly dependent on their temperature. Consequently, effective and energy-saving battery cooling systems are required. This study proposes a secondary-loop liquid pre-cooling system which extracts heat energy from the battery and uses a fin-and-tube heat exchanger to dissipate this energy to the ambient surroundings. The liquid then passes through a chiller to complete the cooling loop. The air-conditioning system is also used to cool the battery only if the temperature of the cooling water exceeds the maximum permissible temperature. The cooling load of the air-conditioning system is thus greatly reduced. The feasibility of the proposed cooling system is demonstrated experimentally under four simulated seasonal environmental conditions, namely high summer (35 °C), mean summer (30 °C), spring and fall (20 °C), and winter (7 °C). The results show that the pre-cooling system can dissipate 1000 W of battery heat in high summer, 2000 W in low summer, 3167 W in spring and fall, and more than 4000 W in winter. In other words, the pre-cooling system greatly reduces the cooling load of the air-conditioning system, and hence significantly reduces its energy consumption.
A Choice Experiment Model for Sustainable Consumer Goods: A Systematic Literature Review and Workflow Design
Authors: Saija Maria Elena , Daniotti Sara , Bosco Diego , Re Ilaria
Published: September 2023

Although various methodological biases have been shown, the choice experiment (CE) literature has confirmed the relevance of sustainability in consumers’ purchase choices. Analysing 186 case studies through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, this study defines the state-of-the-art and future perspectives of the CE approach, allowing us—for the first time—to evaluate in a single study all variables to be considered for setting up the CE questionnaire, with a focus on the selection of attributes and levels, maximising the reliability of the result, and minimising potential method biases. This paper defines a standardised workflow to expand and refine a sustainability perspective that can potentially drive cross-cutting CEs in every consumer good by investigating the accuracy of characteristics driving the willingness to pay (WTP) a premium price for greener consumer goods. Most of the studies analysed in this article concern food products (92%), and around half (51%) focus on sustainability-related aspects, frequently described in generic terms. The results show how defining an adequate number and type of attributes and levels characterising the target product is crucial for a bias-reduced study. These need to be concrete and familiar, and using labels is essential to enhance informed choice, with sustainability being a far-reaching concept with multifaceted definitions. Moreover, choosing a neutral target product, defining the correct sample size, selecting a balanced and representative group of respondents, and using the right analysis model can also minimise potential bias.
q-Rung Orthopair Fuzzy Archimedean Aggregation Operators: Application in the Site Selection for Software Operating Units
Authors: Seikh Mijanur Rahaman , Mandal Utpal
Published: September 2023

The q-rung orthopair fuzzy (q-ROF) set is an efficient tool for dealing with uncertain and inaccurate data in real-world multi-attribute decision-making (MADM). In MADM, aggregation operators play a significant role. The majority of well-known aggregation operators are formed using algebraic, Einstein, Hamacher, Frank, and Yager t-conorms and t-norms. These existing t-conorms and t-norms are some special cases of Archimedean t-conorms (ATCNs) and Archimedean t-norms (ATNs). Therefore, this article aims to extend the ATCN and ATN operations under the q-ROF environment. In this paper, firstly, we present some new operations for q-ROF sets based on ATCN and ATN. After that, we explore a few desirable characteristics of the suggested operational laws. Then, using these operational laws, we develop q-ROF Archimedean weighted averaging (geometric) operators, q-ROF Archimedean order weighted averaging (geometric) operators, and q-ROF Archimedean hybrid averaging (geometric) operators. Next, we develop a model based on the proposed aggregation operators to handle MADM issues. Finally, we elaborate on a numerical problem about site selection for software operating units to highlight the adaptability and dependability of the developed model.

Published: September 2023

This paper investigates the ion-acoustic wave structures in fluid ions for the Benjamin–Bona–Mahony–Peregrine–Burgers (BBMPB) equation. The various types of wave structures are extracted including the three-wave hypothesis, breather wave, lump periodic, mixed-type wave, periodic cross-kink, cross-kink rational wave, M-shaped rational wave, M-shaped rational wave solution with one kink wave, and M-shaped rational wave with two kink wave solutions. The Hirota bilinear transformation is a powerful tool that allows us to accurately find solutions and predict the behaviour of these wave structures. Through our analysis, we gain a better understanding of the complex dynamics of ion-acoustic waves and their potential applications in various fields. Moreover, our findings contribute to the ongoing research in plasma physics that utilize ion-acoustic wave phenomena. To show the physical behaviour of the solutions, some 3D plots and their respective contour level are shown, choosing different values of the parameters.
Permanent Solutions for MHD Motions of Generalized Burgers’ Fluids Adjacent to an Unbounded Plate Subjected to Oscillatory Shear Stresses
Authors: Fetecau Constantin , Akhtar Shehraz , Moroşanu Costică
Published: September 2023

Closed-form expressions have been obtained to characterize the non-dimensional velocity and corresponding non-trivial shear stress in the context of two magnetohydrodynamic (MHD) motions exhibited by incompressible generalized Burgers’ fluids. These motions occur over an infinite plate, which subjects the fluid to oscillatory shear stresses. The obtained solutions represent the first exact analytical solutions for MHD motions of such fluids under the condition of shear stress prescribed along the boundary. The establishment of these solutions relies upon the utilization of a perfect symmetry existing between the governing equations of fluid velocity and shear stress. To validate the results, a comprehensive analysis has been undertaken using two distinct methods. This validation process is further substantiated through graphical representation, demonstrating the congruence between the obtained solutions. Additionally, the convergence of the initial solutions, obtained through numerical techniques, towards their corresponding permanent counterparts has been visually established. This graphical depiction not only substantiates the accuracy of the solutions but also provides insights into the temporal evolution of the system toward its permanent state. An insight to characterize the non-dimensional shear stresses in the context of two values of the magnetic parameter is to identify that the permanent state is reached at an earlier time and the absolute magnitude of fluid velocity is reduced in the presence of an applied magnetic field.
Synergy Management of a Complex Industrial Production System from the Perspective of Flow Structure

Published: September 2023

Modern industry has become very complex and requires an equally complex engineering technology system, which includes resource utilization, energy conversion, product research and development, technological innovation, environmental protection and industrial ecology, and other aspects of the system. Continued development of large-scale, streamlined, and continuous processes is critical; however, there are also problems such as data redundancy, overcapacity, redundant construction, and waste of resources. Based on the system synergy theory, this paper introduces the system analysis method from the perspective of flow structure, with the purpose of solving the management defects of complex industrial production systems. First, we analyze the complex industrial production system as a collaborative structure of three subsystems: material flow, energy flow, and information flow. The following concepts are clarified: “material flow is the main body, energy flow is attached to and drives material flow, material flow and energy flow generate information flow, and information flow reversely drives material flow and energy flow”. Secondly, the collaborative evolution process of the complex industrial production system is divided into three periods, which are the generation period, the stalemate period, and the maturity period, and a synergy degree evaluation model is established, which considers the Theil index and subsystem gray correlation method, and extends the dynamic differential equation model of three-stage collaborative evolution. Subsequently, we used MATLAB numerical simulation to demonstrate that the collaborative evolution of production systems is related to four aspects. They are the self-organizing ability of the system, the dominant role of order parameters, the competition and cooperation between order parameters, and whether mutations can become order parameters. At the same time, it was also found that it is basically independent of other factors, such as attenuation inertia. Then, the self-organizing map network (SOM) algorithm was used for the rapid identification of mutation data. Finally, we use the empirical research of SG enterprises to show that their production level and management system are advanced, but they were in a non-cooperative state from 2014 to 2021. In 2022, they had the basic conditions and trends to enter the synergistic generation period, and a synergistic management model is required. At the end of the article, we give a collaborative management method for complex industrial enterprises with a good management foundation. These include the management mechanism based on flow structure collaboration and the management path based on collaborative evolution. Of course, the management countermeasures given in this study are also applicable to other complex process-based industrial enterprises.

Published: September 2023

Celluloid, the predecessor to plastic, was synthesized in 1869, and due to technological advancements, plastic products appear to be ubiquitous in daily life. The massive production, rampant usage, and inadequate disposal of plastic products have led to severe environmental pollution. Consequently, reducing the employment of plastic has emerged as a pressing concern for governments globally. This review explores microplastics, including their origins, absorption, and harmful effects on the environment and humans. Several methods exist for breaking down plastics, including thermal, mechanical, light, catalytic, and biological processes. Despite these methods, microplastics (MPs, between 1 and 5 mm in size) continue to be produced during degradation. Acknowledging the significant threat that MPs pose to the environment and human health is imperative. This form of pollution is pervasive in the air and food and infiltrates our bodies through ingestion, inhalation, or skin contact. It is essential to assess the potential hazards that MPs can introduce. There is evidence suggesting that MPs may have negative impacts on different areas of human health. These include the respiratory, gastrointestinal, immune, nervous, and reproductive systems, the liver and organs, the skin, and even the placenta and placental barrier. It is encouraging to see that most of the countries have taken steps to regulate plastic particles. These measures aim to reduce plastic usage, which is essential today. At the same time, this review summarizes the degradation mechanism of plastics, their impact on human health, and plastic reduction policies worldwide. It provides valuable information for future research on MPs and regulatory development.
Safety of Interchanging the Live Attenuated MAV/06 Strain and OKA Strain Varicella Vaccines in Children
Authors: Kang Hyun Mi , Kim Gwanglok , Choe Young June
Published: September 2023

Two live attenuated varicella vaccine (VZV) strains have been mainly used across the globe: MAV/06 and OKA strains. We aimed to explore the safety of interchanging the two VZV strains for primary and booster immunizations. South Korea’s vaccine adverse event reporting system (VAERS) was accessed and searched to find filed reports of all adverse events (AEs) following immunization with the second dose of the varicella vaccine. The electronic medical records were reviewed for all visits to the hospital following the second dose of the varicella vaccine. Of the total 406 study participants, 27.5% (n = 112) were in the MAV/06–MAV/06 group, 30.3% (n = 123) in the MAV/06–OKA, 17.5% (n = 71) in the OKA–MAV/06 group, and 24.6% (n = 100) in the OKA–OKA group. Mean age at immunization with the first dose was 1.10 (standard deviation [SD] ±0.34) years old, and second dose was 4.77 (SD ± 1.13) (p = 0.772 and 0.933, respectively). There were no filed reports of AEs following the second dose in the national VAERS. Hospital visit records showed a total of 10.3% (95% confidence interval [CI], 7.6–13.7) (n = 42) had recorded AEs following the 2nd administered dose; however, only 0.7% (95% CI, 0.2–2.4) (n = 3) were regarded as possibly vaccine related. Two patients in the MAV/06–OKA group were diagnosed with Henoch-Schonlein purpura after the second dose; however, both had also received the MMR vaccine on the same day. No safety signals associated with interchanging the MAV/06 and OKA strain live attenuated varicella vaccines were observed in this patient cohort of healthy children.

Published: September 2023

COVID-19 vaccine (CV) acceptance rates remain suboptimal in children. Emergency departments (EDs) represent a unique opportunity to improve vaccination rates, particularly in underserved children. Little is known about the presence or reach of CV programs in US EDs. We assessed, via a cross-sectional survey of pediatric ED physicians, the number of EDs offering CVs to children, the approximate numbers of vaccines administered annually, and the perceived facilitators/barriers to vaccination. The proportion of EDs offering CVs is reported. Chi-square tests compared facilitators and barriers among frequent vaccinators (≥50 CVs/year), infrequent vaccinators (<50 CVs/year), and non-vaccinators. Among 492 physicians from 166 EDs, 142 responded (representing 61 (37.3%) EDs). Most EDs were in large, urban, academic, freestanding children’s hospitals. Only 11 EDs (18.0%) offer ≥1 CV/year, and only two (18.2%) of these gave ≥50 CVs. Common facilitators of vaccination included the electronic health record facilitation of vaccination, a strong provider/staff buy-in, storage/accessibility, and having a leadership team or champion. Barriers included patient/caregiver refusal, forgetting to offer vaccines, and, less commonly, a lack of buy-in/support and the inaccessibility of vaccines. Many (28/47, 59.6%) EDs expressed interest in establishing a CV program.

Patients with autoimmune inflammatory rheumatic diseases (AIIRDs) are at increased risk for severe infections. Vaccine responses and safety profiles may differ between AIIRD patients and the general population. While patients with autoimmune inflammatory rheumatic diseases (AIIRDs) often experience diminished humoral responses and reduced vaccine efficacy, factors such as the type of immunosuppressant medications used and the specific vaccine employed contribute to these outcomes. Notably, individuals undergoing B cell depletion therapy tend to have poor vaccine immunogenicity. However, despite these considerations, vaccine responses are generally considered clinically sufficient. Ideally, immunosuppressed AIIRD patients should receive vaccinations at least two weeks before commencing immunosuppressive treatment. However, it is common for many patients to already be on immunosuppressants during the immunization process. Vaccination rarely triggers flares in AIIRDs; if flares occur, they are typically mild. Despite the heightened infection risk, including COVID-19, among AIIRD patients with rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, and other diseases on immunosuppressants, the vaccination rates remain suboptimal. The future directions of vaccination in the era of immunosuppression will likely involve customized vaccines with enhanced adjuvants and alternative delivery methods. By addressing the unique challenges faced by immunosuppressed individuals, we may improve vaccine efficacy, reduce the risk of infections, and ultimately enhance the health outcomes. Additionally, clinical trials to evaluate the safety and efficacy of temporarily discontinuing immunosuppressants during vaccination in various AIIRDs are crucial.
Evaluation of Regional Water Ecological Economic System Sustainability Based on Emergy Water Ecological Footprint Theory—Taking the Yellow River Basin as an Example
Authors: Wu Zening , Chen Xiangyu , Di Danyang
Published: September 2023

In the article, on the basis of quantifying the emergy water ecological footprint, a sustainability evaluation system for the overall water ecological economic system of the basin and each province (region) was proposed. And using the subjective and objective combination of the Analytic Hierarchy Process (AHP) and Entropy Weight Method (EWM) to determine the weight of the indicator system, a TOPSIS model for sustainability evaluation was constructed. And taking the Yellow River Basin as an example, the results indicate that (1) Throughout the entire basin, the sustainability of the water ecological economic system showed a fluctuating upward trend year by year during the study period, from 0.37 to 0.51. (2) In each province (region), the sustainability of the water ecological economic system had gathered in space. The overall sustainability level of the upstream Sichuan, Qinghai and Gansu provinces is high, always at level (I). The overall sustainability level of the midstream Ningxia and Neimenggu was low, always at level (IV). The overall sustainability level of the downstream Shaanxi, Shanxi, Henan and Shandong provinces is high, rising gradually over time, from level (III) to level (II) or (I). Against the backdrop of the rapid development of the economy and society, the contradiction between economic and social development, ecological environment protection, and sustainable utilization of water resources is becoming increasingly severe, which has become a key factor restricting the sustainable development of the ecological economic system in Yellow River Basin. Multidimensional comprehensive evaluation of the sustainability level of the regional water ecological economic system is a prerequisite for identifying sustainable development issues in the Yellow River Basin, and also the basis for formulating targeted policies for sustainable utilization of regional water resources and high-quality economic development.

Authors: Stevens Julie , Miranda Rose , Pype Peter , Eecloo Kim , Deliens Luc , De Vleminck Aline , Pardon Koen
Published: September 2023

Background

Advance care planning (ACP) is an iterative communication process about patients’ preferences for future care. In general practice, there are barriers to ACP at patient, GP, and healthcare-system levels. A complex intervention may be necessary to reduce barriers.

Aim

To evaluate the effects of a complex ACP intervention for patients with chronic, life-limiting illness in general practice (ACP-GP).

Design and setting

A cluster-randomised controlled trial was undertaken in Belgian general practice.

Method

ACP-GP included a patient workbook, GP training, ACP conversations, and a documentation template. The control group received usual care. Outcomes were the 15-item ACP Engagement Survey for patients and the ACP Self-Efficacy scale for GPs. Linear mixed models evaluated differences at 3 months (T1, effectiveness evaluation) and 6 months (T2) post-baseline. Analysis was intention-to-treat.

Results

In total, 35 GPs and 95 patients were randomised. Patient ACP engagement did not differ between the intervention and control group at T1 (baseline-adjusted mean difference = 0.34; 95% confidence interval [CI] = −0.02 to 0.69;P= 0.062) or T2 (baseline-adjusted mean difference = 0.20; 95% CI = −0.17 to 0.57;P= 0.28). For GP ACP self-efficacy, there were no significant differences between groups at T1 (baseline-adjusted mean difference = 0.16; 95% CI = −0.04 to 0.35;P= 0.11) or at T2 (baseline-adjusted mean difference = 0.11; 95% CI = −0.09 to 0.31;P= 0.27).

Conclusion

ACP-GP did not improve patient engagement and GP self-efficacy more than usual care. Both groups showed patterns of increase from baseline. Trial procedures and the COVID-19 pandemic may have increased awareness about ACP.
Aspects of Arbitral Awards in the Indonesian Justice System: Historical and Theoretical Review
Authors: Agus Azwir
Published: September 2023

This study aims to analyze aspects of arbitral awards in the Indonesian justice system from historical and theoretical perspectives. The Arbitration Law confirms that arbitral awards have the same legal force as court decisions. The method used in this research is normative legal method. This legal method focuses on the analysis of existing legal norms, including statutory regulations, court decisions, legal principles, and other legal documents in this context, namely, aspects of arbitral awards in the Indonesian justice system. The results of the study show that the implementation of the arbitral award by the parties must be seen as a consequence of choosing arbitration to resolve the dispute, it is the parties who choose their own judges, even for their choice of law, then the implementation of the arbitral award is consciously a necessity of the parties themselves. Arbitration awards can be annulled in the justice system in Indonesia as a form of protection for justice and legal order. Grounds for annulment of an arbitral award, as provided for in the Arbitration Act, may include a breach of procedure, the incompetence of the arbitrator, or an award that violates decency or public decency. Arbitration awards are an important tool in the dispute resolution system in Indonesia, especially in the business and investment sphere.

Abstract: Stunting is a linear growth disorder that is not appropriate for the child's age due to malnutrition. Malnutrition in stunted children can affect bone growth. The process of inhibited bone growth will affect the process of maturation of the periodontal bones that support the teeth being hampered so that children can experience delays in tooth eruption. This study aimed to describe the eruption of the permanent lower central incisors in stunted children at Sekolah Dasar (elementary school) Koto Balingka West Pasaman. This was a quantitative-descriptive-observational study with a case control design. Samples obtained by using purposive sampling technique were 68 children consisting of 34 (50%) stunted children and 34 (50%) normal children aged 6-7 years in the working area of the Parit Koto Balingka Health Center. Univariate analysis was presented in the form of frequency and percentage distributions. The results showed that among stunted children, 22 (64.7%) had not erupted permanent lower central incisors meanwhile 12 (35.3%) children did. Moreover, among normal children, 6 (17.6%) had not erupted permanent lower central incisors meanwhile 28 (82.4%) did. In conclusion, most children aged 6-7 years with stunting have not yet had erupted permanent lower central incisors, meanwhile most children with normal nutritional status have erupted permanent lower central incisors, with a mean age of eruption at 7 years. Keywords: stunting; tooth eruption; permanent lower central incisor; malnutrition
Development of plastic scintillators loaded with perovskite quantum dots and wavelength shifting molecules
Authors: Sato Atsushi , Fujimoto Yutaka , Asai Keisuke , Koshimizu Masanori
Published: September 2023

We have deloveloped plastic scintillators loaded with perovskite quantum dots (QDs) to obtain efficient scintillation and enhanced detection efficiency of high-energy photons such as X-rays and gamma rays. In previous studies, the loading of the perovsite QDs was not successful to achieve efficient scintillation owing to the severe self-absorption of the QD emission, which is caused by small Stokes shift of the QDs. In the present study, we added wavelength shifting molecules to suppress the self-absorption. Among three samples, we have succeeded in enhancement in the scintillation light yield and shortening of the scintillation decay by the suppression of the self-absorption in polustyrene-based plastic scintillators added with butyl-PBD, QD-P450, and Coumarin6, and butyl-PBD, QD-P510, and Nile red. This result indicates that it is necessary to avoid the self-absorption to fully exploit the fast and efficient emission of the perovskite QDs.

The purpose of this study was to predict the percentage and yield of chamomile essential oils using the artificial neural network system based on some soil physicochemical properties. Several habitats of chamomile cultivation were investigated and 100 soil samples were shipped to the greenhouse. The maximum and minimum of pH, EC, K, OM (organic matter), CCE (calcium carbonate equivalent), and clay in soils were 8.75-7.94, 1.6-1.0, 381-135, 2.30-0.22, 69-16, and 55.6-32.0, respectively. Growth indices, essential oil percentage, and yield were measured. Artificial neural network modeling was carried out to predict the essential oil concentration and yield using three groups of soil properties as a predictor: 1- nitrogen (N), phosphorus (P), potassium (K), and clay; 2- pH, EC, organic matter (OM) and clay; 3- CCE, clay, silt, sand, N, P, K, OM, pH, and EC. So, three pedotransfer functions (PTFs) were developed using the multi-layer perceptron (MPL) with Levenberg-Marquardt training algorithm for estimating chamomile essential oil content. Results evaluation of the accuracy and reliability of showed that, the third PTF (PTF3) which developed by all independent variables had the highest accuracy and reliability. Results also showed that, it is possible to predict the concentration and yield of chamomile essential oil based on soil physicochemical properties. This issue is important in terms of land suitability, identify areas susceptible to chamomile cultivation and planning for essential oil yields.

Construyendo valores implica un proceso de comprensión articulado a principios éticos que precisan a las personas como seres responsables, solidarios y críticos, suscitando crear procesos que promuevan condiciones y guíen el actuar del individuo o grupos que definan manera en la que la persona se relaciona consigo misma y con el entorno. Por ello la implicación conduce a una educación en valores de las personas que irrumpirán para lograr un mundo ideal con un aprendizaje orientado a los valores que motivan la acción del ser humano con la naturaleza, fortaleciendo espacios para transformar la sociedad con mejor calidad de vida y respeto hacia los demás. Hoy más que nunca, querer los entornos naturales implica ser conscientes de nuestro impacto en el planeta. En ese contexto, el artículo tiene como propósito develar la construcción en valores desde una visión ambientalista con una mirada comprensivo edificadora en estudiantes universitarios. El abordaje metodológico se basó en una revisión del tipo analítico hermenéutico, con recopilación de literatura referente al tema y disponible en la web. Los resultados obtenidos indicaron la necesidad de revisar la didáctica, el currículo y la evaluación para la incorporación de acciones que promueva en los procesos de enseñanza y de aprendizaje el desarrollo de competencias transversales básicas relacionadas con la sostenibilidad y adecuar su práctica al desarrollo pedagógico. Se concluye que debe asumirse los valores desde una visión ambientalista como disciplina que ofrece oportunidades para comprender los procesos que contribuyen a la comprensión de los mecanismos bajo una mirada comprensivo edificadora, en torno a la enseñanza, formación y aprendizajes desde la reflexión, relacionando cognición y conciencia crítica para desarrollar actitudes que dan lugar a logros educativos, además, permitir a los estudiantes desarrollar sus potencialidades para que incorporen alternativas de innovación en los procesos áulicos mediante acciones prácticas concretas.
