Authors: Sánchez Proaño Renato , Cerón Pánchig Carlos , Landeta Jibaja Karla
Published: August 2023

La cuenca del río Pisque en el Ecuador tiene alta presencia de industria florícola, desarrollándose aquí un estudio cuyo objetivo es la estimación de la magnitud de las pérdidas de plaguicidas que ingresan al agua fluvial por fuentes como escorrentía superficial, contacto con el suelo, permeado de una escorrentía previa o por infiltración, y que pueden ser medidas en el cauce final del río Pisque antes de su desembocadura. Para conocer los pesticidas utilizados se han realizado encuestas a los productores florícolas. Las mediciones se realizaron en los ríos Granobles y Guachalá, afluentes del río Pisque, y en dos puntos separados en el mismo río Pisque, uno inmediatamente después de la conjunción entre los dos afluentes y un punto antes de su desembocadura al siguiente río. Los aforos de caudal fueron mensuales desde junio 2018 hasta mayo 2019; cómo método de muestreo se usaron dispositivos pasivos SPMD y POCIS durante los tres meses secos, de junio a agosto de 2018. Para obtener las tasas de retención de los dispositivos pasivos se realizó una calibración con los plaguicidas en laboratorio mediante un canal hidrodinámico. De las encuestas se identificaron 24 ingredientes activos principales, en su mayoría compuestos con toxicidades Tipo III y Tipo IV. Según los resultados del modelo, la carga fluvial de pesticidas en aguas superficiales fue de 2982,24 Kg entre los meses de junio de 2018 a mayo de 2019, existiendo degradación ambiental de varios compuestos a lo largo del tramo del río.

Published: August 2023

La acuicultura contribuye de manera importante a la fuente de alimento destinado al consumo humano. La tilapia Oreochromis niloticus es uno de los peces principales de la producción acuícola, por lo que las fases de su reproducción son vitales para asegurar la calidad y cantidad de organismos disponibles para los sistemas de producción. Los parámetros reproductivos en actividades acuícolas de peces, como la fertilidad, fecundidad, diámetro de huevos, índice gonadosomático, tasa de supervivencia en larvas y alevines, entre otros, son de relevancia para una producción económicamente rentable y sostenible, y estos pueden variar según la dieta, condiciones ambientales, edad, características genéticas de los peces o la calidad del agua. Por lo anterior, este documento tiene como objetivo identificar los parámetros reproductivos que tengan una influencia en la producción de crías de tilapia presentar una descripción general de forma sencilla los diferentes parámetros reproductivos involucrados y de consideración en actividades de producción acuícola de crías de tilapia. Se realizó una búsqueda de la información en los últimos 20 años incorporada en diversas bases de datos especializadas. En esta investigación se recopila la información a la actualidad sobre los parámetros reproductivos en tilapia, y los resultados indican que no existe un parámetro reproductivo más importante que otro, ya que es un cúmulo de factores y sinergia que intervienen en la reproducción, por lo que resulta necesario establecer planes de manejo claro e investigación particular en los sistemas de producción para mejorar y potencializar su producción. El conocimiento de los parámetros reproductivos de la tilapia puede ayudar a disminuir los costos de producción para establecer planes de manejo claro e investigación particular en los sistemas de producción para mejorar y potencializar su producción.

Se desconoce el estatus sanitario de ganaderías que no están dentro del programa oficial de control de Brucelosis en la provincia del Azuay, pudiendo existir zonas con mayor frecuencia de rebaños seropositivos. Este trabajo pretende determinar la prevalencia y factores de riesgo asociados a brucelosis bovina en predios lecheros. Se llevó a cabo un estudio epidemiológico en 436 fincas, para lo cual se tomaron muestras de leche de productores en centros de acopio, camiones recolectores y hatos. Se usó una encuesta georeferenciada a fin de recopilar información del manejo de las ganaderías. La leche se analizó mediante ELISA-indirecto, y 37 fincas resultaron seropositivas, obteniendo una prevalencia de 8,5%. Los porcentajes de seropositividad fueron: Cuenca (14,84%), Girón (23,07%), Nabón (8,21%), Oña (11,53%), San Fernando (33,33%), Sevilla de Oro (7,14%), Sigsig (4,16%). Se realizaron las pruebas Rosa de Bengala y ELISA-competitivo a bovinos que aportaron al pool de leche en 34 ganaderías, estableciéndose una concordancia del 100% de ELISA-indirecto para detectar fincas seronegativas. En el análisis de regresión logística se determinó una asociación significativa (P < 0;05) entre la seropositividad y factores como: ubicación geográfica, extensión de la finca, sistema de explotación, presencia de otras especies domésticas, eliminación de restos placentarios, sistema de reproducción, teniendo una mayor probabilidad de seropositividad las ganaderías que presentaron abortos (OR = 2;71), problemas de celo (OR = 2;09), nacimiento de terneros débiles (OR=3,24) y manejo extensivo (OR = 3;67). Estos hallazgos constituyen evidencia serológica que Brucella spp. circula en ganaderías de la zona.
THE INFLUENCE OF PURCHASE ATTITUDES AND REVIEWS ON USERS’ PURCHASE INTENTIONS IN SOCIAL MEDIA SETTINGS
Authors:   University of Dubrovnik, Department of Economics and Business, Croatia, Matić Šošić Matea , Vojvodić Katija
Published: August 2023

The rapid growth of social media provides businesses with a new venue for users to make a purchase, as well as the opportunity to post their reviews and comments on products, which can greatly influence the purchase decision process of potential users. The social media platform generates both positive and negative reviews and comments that can influence users' purchase behaviour. In order to gain a deeper understanding of consumer purchase behaviour on social media, the study examines how positive and negative reviews and comments can affect purchase attitudes and pre-purchase behaviour. It also examines how social media users' purchase attitudes contribute to their specific purchase behaviours such as pre-purchase and post-purchase behaviours. The research instrument was a questionnaire, and data were collected through social media platforms using Google forms. Descriptive statistics and Spearman correlation coefficients were used to achieve the objective of this study. The research sample consisted of 162 social media users. The results suggest that there is a positive relationship between purchase attitude and pre-purchase and post-purchase behaviour. The results also suggest that there is a positive relationship between positive and negative reviews and comments, purchase attitude, and pre-purchase behaviour.
Evaluating a Prospective Fault-Based Stress-Transfer Forecast for the M 7.9 Wenchuan Earthquake Region, 15 Years Later
Authors: Parsons Tom , Ji Chen , Kirby Eric
Published: August 2023

Four days after the 12 May 2008 M 7.9 Wenchuan earthquake struck the Sichuan region of China, we submitted a prospective earthquake forecast based on transfer of stress from the mainshock onto significant faults crossing through populated areas. We identified where the largest aftershocks were likely to occur that could cause loss of life. We returned the revised article to the journal on 5 June 2008, marking the last day of our observation period. The primary testable features are locations and focal mechanisms of larger (M ≥ 4.5) earthquakes; did these events happen on or very near the faults we said they would? Did they have the same strikes, dips, and rakes as the faults we modeled? In retrospect, is the stress transfer method consistent with all M ≥ 4.5 earthquakes that occurred? We find all but one M ≥ 4.5 aftershock with known focal mechanisms located on stress-increased faults, and their focal mechanism parameters overlap with geological characteristics we used in making calculations. Six of the seven lethal M > 4.5 earthquakes that occurred in the region since 5 June 2008 were located on stress-increased faults, with the lone exception triggered by hydraulic fracturing.

Authors: Bachchhav Bhanudas , Chaitanya Shrikant
Published: August 2023

Selection of electrode material for spot welding operation is a complex task due to compromising properties such as electrical conductivity and the strength of material, although limited materials possess them collectively. This research aims to rank eight discrete classes of Cr-Zr, Cu-Be, Cu-Cd, Cu-Cr-Zr, Cu-Ti and Cu-W spot welding electrode materials based on PROMETHEE, VIKOR and WASPAS methods. Preliminary screening of essential attributes was performed using Analytical Hierarchy Process (AHP). It was observed that Cu-Cr-Zr is ranked as the best candidate material by all three MADM methods. However, the selection is based on availability, manufacturability, environment protection rules and cost. This paper suggested an approach for electrode manufacturers and end users to select reliable spot welding electrode material to achieve high weld quality
Investigation of Outdoor Air Temperature Effects on Heat Recovery in Cross Flow Heat Exchanger
Authors: SELVER Ramazan
Published: August 2023

A heat recovery device was designed and manufactured to provide air-to-air heat transfer by using a cross-flow heat exchanger on the pipe bundles. For this purpose, different cold air inlet temperature values and the temperature values of high temperature hot exhaust gases in the tube bundle heat exchanger were determined as operating parameters. According to the temperature increase of the cold air entering the heat exchanger; The kinematic viscosity values of the air increased and the maximum Reynolds number in the flow state of the air passing through the test heat exchanger was decreased. The average Nusselt numbers and average air convection coefficients in the flow of air decreased according to the temperature increase of the cold air. According to the temperature increase of the cold air entering the heat exchanger, both the analytical and experimental outlet temperature values of the cold air leaving the heat exchanger increase very close to each other. With this increase, the amount of heat transferred from the fluid to the fluid in the heat exchanger decreases. While the temperature value of the cold air entering the heat exchanger increases, the temperature difference value of the advancing air from the beginning to the outlet (ΔT= Ts – Ti) decreases. Due to this decrease, a decrease was observed in the amount of heat transfer.
Effect of oral nifedipine or combined with sildenafil citrate for management of threatened preterm labour randomized trial
Authors: Singh Shreya , Sheela S R
Published: August 2023

In developing countries, preterm birth is a leading cause of neonatal and infant illness and mortality. In southern India, there is an increase in preterm delivery and the prevalence is about 5-8%. It is related with severe suffering for both women and babies as well as long-term disabilities; hence interventions to prevent preterm birth are critical. The threatened preterm labor can be postponed by using “tocolytic” therapy in order to transfer the patient to a center with a neonatal intensive care unit or administer corticosteroids. It helps in the prevention or treatment of respiratory morbidity.

To assess the efficacy of nifedipine combined with sildenafil citrate and nifedipine alone in threatened preterm labor and also to determine the maternal and perinatal outcome.

The final analysis comprised a total of 60 subjects. There were 30 people in Group A (Nifedipine) and 30 people in Group B (Sildenafil +Nifedipine).

The mean age of the participants was identified as 21.07 ± 3.31 years and 22.87 ± 3.15 years in group A and B respectively. The cause of preterm was identified as idiopathic in the majority of the women in group A with 83.33 and in group B with 70% and 16.67%. Maternal side effects in group A were tachycardia, palpitations, nausea, and vomiting with 26.67%, 3.33%, and 16.67%, while in group B, tachycardia, facial flushing, palpitations, and headache were identified with 10%, 6.67%, 10%, 6.67%. Respiratory distress syndrome, Neonatal intensive care unit admission, perinatal death, alive and healthy neonates were identified with 16.67%, 23.33%, 20%, and 53.33% in group A, whereas it was identified with 23.33%, 36.67%, 3.33%, and 56.67% respectively. The rate of success was higher with group B (93.3%) as compared in group A (50%).

: The combination of sildenafil citrate and nifedipine is more effective than nifedipine alone in avoiding approaching preterm labor.

Published: August 2023

Trichoderma asperellum is an antagonistic fungus, which has the ability to inhibit the growth of pathogens in target environment. The study on compatibility of T. asperellum with fungicide molecules was carried out to know its compatibility with different classes of fungicide molecules during the studies on antagonistic potential of Trichoderma sp. against Fusarium oxysporum f. sp. ciceris causing chickpea wilt. In the present study, each of six popular systemic, non-systemic and combi-fungicide molecules were used to study the compatibility with bioagent Trichoderma asperellum. The fungicides were used at three different concentrations, i.e., systemic fungicides at 0.05, 0.1 and 0.15 per cent and non-systemic and combi fungicides at 0.1, 0.2 and 0.3 per cent concentrations by using poisoned food technique. Among six systemic fungicides, only azoxystrobin was highly compatible, whereas other systemic fungicides were incompatible showing 100 per cent inhibition of T. asperellum. Among six non-systemic fungicides, propineb, copper oxychloride and copper hydroxide were compatible at all three concentrations tested. However, mancozeb was compatible at lower concentrations but incompatible at higher (0.3%) concentrations. Further, thiram and captan were highly incompatible. Among six combi fungicides, copper oxychloride + copper hydroxide and cymoxanil + mancozeb were compatible with T. asperellum.

Temephos and deltamethrin insecticides have been widely used to control Aedes aegypti in Bagua Grande district, Utcubamba, Amazonas, Peru. For this reason, the enzyme profile related to temephos and deltamethrin resistance in A. aegypti from Bagua Grande were evaluated. To determine the resistance status, bioassays were conducted with temephos using larvae and with deltamethrin using adults. Enzymes profile were evaluated by biochemical assays of αEST, βEST, GSTs, and remaining AChE in survived individuals to selective doses of both insecticides. Esterase patterns of larvae and adults were observed by native-PAGE. The population showed temephos susceptibility, with RR 50 = 3.06 and 83.95% mortality, and deltamethrin resistance with a mortality equal to 1.21%. Enzyme assays revealed highly altered levels of GST and AChE in larvae and altered levels of αEST and highly altered levels of GST and AChE in adults. Native-PAGE only showed common bands to susceptible strain. Results suggest that the presence of GST and AChE do not improve temephos resistance, while αEST, GST and AChE mechanisms are involved in deltamethrin resistance in A. aegypti from Bagua Grande.

Grapevine powdery mildew is one of the most important plant diseases widely affecting crops in many countries. The main aim of the present study was to use Ampelomyces quisqualis isolates to suppress the powdery mildew of grapes under field conditions. The findings revealed a strong correlation between the mycoparasite, Ampelomyces quisqualis and the grape powdery mildew pathogens, suggesting its potential for effective control. The results revealed that a single spray of A. quisqualis @ 2.0 per cent (MDU1) succeeded by two sprays of Trichoderma asperellum @ 2.0 per cent (Tasp,7) were found to be effective against Erysiphe necator. In addition, liquid formulation of A. quisqualis isolate MDU1 (2% w/v) as a foliar spray at 2% containing 2 × 106 spores ml-1 the during initial occurrence of the disease up to three sprayings at 15 days interval was found to be best. Thus, a liquid formulation of A. quisqualis isolate MDU1 proved effective in managing grapes powdery mildew disease under field conditions. The rDNA ITS region of A. quisqualis isolates was analyzed at the molecular level, and the resulting sequences were subjected to GC-MS analysis. The secondary metabolite identification using GC-MS revealed the presence of antimicrobial compounds, including squalene with the highest peak of 4.643 percent, octadecanoic acid with 3.862 percent, tetradecanoic acid with 3.600 percent, and 9,12-octadecadienoic acid (Z,Z) with 1.451 percent. These bioactive compounds revealed by GC-MS analysis in crude extracts of A. quisqualis had a stronger antifungal activity against E. necator.

Authors: T. M. MANJUNATH
Published: August 2023

The eggs, larvae and pupae of the rice moth, Corcyra cephalonica (Lepidoptera, Pyralidae), have been found to serve as factitious/ alternative hosts for mass-production of at least 78 species of natural enemies – 60 parasitoids, 18 predators – belonging to 35 genera in 18 families under 8 orders that include Hymenoptera, Diptera, Arachnida and Nematoda for parasitoids while Coleoptera, Hemiptera, Hymenoptera and Neuroptera for predators. A list of these natural enemies is provided. Thus, though C. cephalonica is a serious pest of stored grains under natural conditions, it is a boon in laboratories as a factitious host for economic mass production of a variety of parasitoids and predators like Trichogramma, Chrysoperla, etc., which are extensively utilized in augmentative biological control.

Published: August 2023

Corynebacterium diphtheriae (C. diphtheriae) jest pierwotnym patogenem wywołującym błonicę, która zasadniczo występuje w dwóch postaciach: nosowo-gardłowej i skórnej. W związku z powszechnymi szczepieniami przeciwko błonicy, krztuścowi i tężcowi (diphtheria, pertussis and tetanus – DPT) częstość występowania błonicy na świecie znacząco zmalała, na niektórych obszarach zanikając niemal całkowicie. W dzisiejszych czasach ponownie obserwujemy przypadki błonicy, zwłaszcza postaci skórnej, nawet w krajach z wysokim wskaźnikiem wyszczepienia, w związku z nasilającą się migracją z krajów o niższym odsetku zaszczepionych obywateli.
Prezentujemy studium przypadku ukraińskiego imigranta ze zdiagnozowaną błonicą skóry, by zwiększyć świadomość środowiska medycznego o tej powracającej chorobie, jej postaci skórnej oraz związanych z tym nowych wyzwaniach. To pierwszy zaraportowany przypadek zakażenia C. diphtheriae w Polsce od 2005 r. Przeanalizowano najnowsze artykuły dostępne w bazach PubMed i Google Scholar, używając jako kryterium następujących słów kluczowych: „błonica przypadek”, „błonica opis przypadku”, „błonica skóry”. Wybrano artykuły o najwyższej korelacji z ponad 1700 wyników wyszukiwania.
Opis przypadku i analiza publikacji naukowych na temat błonicy skóry pokazują znaczenie tej postaci choroby w nowej, poszczepiennej erze. Twierdzimy, że szczepienia, stosowanie ochrony osobistej podczas kontaktu z pacjentem oraz świadomość środowiska medycznego dotycząca możliwych zagrożeń stają się jeszcze bardziej istotne.

Published: August 2023

Background: Rice is one of the most common cereal crops in India, which has been found attacked by several insect pests including hoppers, stem borer, leaf folder, gall midge and ear head bugs. Farmers typically employ insecticides as preventative and curative management which causes needless issues. Although integrated pest management (IPM) has been recommended to nullify the ill effects of chemicals pesticides, farmers are hesitant to employ the IPM’s components and mostly rely on pesticides. IPM integrates knowledge-based techniques of biological, cultural, physical, host plant resistance and chemical control strategies in order to limit pest populations considered economically acceptable. Present investigation was conducted to evaluate the effectiveness of IPM strategy improving upon the crop productivity. Methods: An Integrated Pest Management (IPM) module comprising of spacing, introduction of natural enemies, application of botanicals, entomopathogenic fungi, installation of yellow sticky traps and chemical pesticide (Thiamethoxam) was assessed in comparison with Farmers Practice (FP) (usual routine followed by the farmer during the cropping season) in the farmer’s fields. Result: The pooled mean data of per cent leaf incidence by Nephotettix virescens ranged between 4.59-6.25% during the two years research in IPM module, while in farmers practices mean leaf damage varied between 8.09-8.61%. Similarly, the leaf damage caused by Nilaparvata lugens ranged between 4.88-7.61% as compared to 8.64-10% in the farmers practices. The BC ration was recorded to be 1: 7.6 and 1:6.85 during 2018 and 2019, respectively.

Published: August 2023

Purpose – The share price of any financial institution fluctuates due to various hidden and visible factors. Predicting share price behavior in the economy and financial marketing theory is crucial but complex. The Industrial Bank of Korea’s (IBK) share prices are also affected by hidden factors, including Korean international trade flow. The study aims to forecast hidden impacts on IBK share prices resulting from the international trade flow in Korea. Design/Methodology/Approach – Two Hidden Markov Model (HMM) approaches are employed, one based on exports, and the other on imports, to identify trends and fluctuations in the hidden states influencing visible states. Findings – The findings reveal a significant positive correlation between IBK share prices and both exports and imports. Notably, increasing exports indicate a 50% probability of IBK share prices rising, while falling imports indicate a 56% chance of IBK share prices increasing. These results demonstrate how changes in exports and imports impact IBK’s share price in the Korean stock market. Research Implications – The research implications are valuable for short- and long-term investors in IBK shares and the Korean stock exchange. This research can help decision-makers identify the relationships between and within the visible/observed states that influence the stock price of IBK.

Published: August 2023

Oncolytic virotherapy has emerged as a promising treatment for human cancers owing to an ability to elicit curative effects via systemic administration. Tumor cells often create an unfavorable immunosuppressive microenvironment that degrade viral structures and impede viral replication; however, recent studies have established that viruses altered via genetic modifications can serve as effective oncolytic agents to combat hostile tumor environments. Specifically, oncolytic vaccinia virus (OVV) has gained popularity owing to its safety, potential for systemic delivery, and large gene insertion capacity. This review highlights current research on the use of engineered mutated viruses and gene-armed OVVs to reverse the tumor microenvironment and enhance antitumor activity in vitro and in vivo, and provides an overview of ongoing clinical trials and combination therapies. In addition, we discuss the potential benefits and drawbacks of OVV as a cancer therapy, and explore different perspectives in this field.

Fat and oils plays one of the major roles in Sri Lankan modern unhealthy diet. The study was guided to collect, analyze, and interpret data about the awareness of general community on edible fat and oil products available in the market and their knowledge about healthy ways of usage. A total of 250 purchasing women were surveyed with a welldeveloped questionnaire. Results revealed that, Coconut oil (71%) is the leading supermarket oil product purchased and consumption of animal fats and oil are very limited (<3%) in Kandy. Educational level affects significantly (P<0.05) on purchasing behavior. Regardless of educational level and working status, price (73%) will be the most significant factor look at during purchasing edible oils. Total of 57% of purchasing women use the same oil for both deep frying and stir frying. Besides, 43% of women keep two different types. From all respondents, 83% use oil more than one time after first cooking. Working women prefer internet and facebook (38%) as the major food related information searching resource, while newspapers (35%) are among non-working women. All in all, lowering the price of healthy fat and community awareness programs will encourage healthy fat and oil purchasing behavior in Sri Lanka.

Authors: Shrahili Mansour , Kayid Mohamed
Published: August 2023

In this paper, we investigate the cumulative historical entropy of the lifetime of an n-component coherent system under the assumption that all system components have failed at time t. Using the system signature, we can calculate the cumulative historical entropy of the system’s lifespan, which is an important aspect in determining a system’s predictability. This research produces a number of significant results, including expressions, bounds, and ordering aspects for this measure. In addition, we offer a method for finding a preferred system based on cumulative Kullback-Leibler discriminating information that is closely related to the parallel system. These findings provide important insights into the predictability and dependability of coherent systems, emphasizing the importance of this field.

Published: August 2023

With the advancement of urbanization in China, effective control of pollutant emissions and air quality have become important goals in current environmental management. Nitrogen dioxide (NO2), as a precursor of tropospheric ozone and fine particulate matter, plays a significant role in atmospheric chemistry research and air pollution control. However, the uneven ground monitoring stations and low temporal resolution of polar-orbiting satellites set challenges for accurately assessing near-surface NO2. To address this issue, a spatiotemporal refined NO2 retrieval model was established for China using the geostationary satellite Himawari-8. The spatiotemporal characteristics of NO2 were analyzed and its contribution factors were explored. Firstly, seven Himawari-8 channels sensitive to NO2 were selected by using the forward feature selection based on information entropy. Subsequently, a 2DCNN-LSTM network model was constructed, incorporating the selected channels and meteorological variables as retrieval factors to estimate hourly NO2 in China from March 2018 to February 2020 (with a resolution of 0.05°, per hour). The performance evaluation demonstrated that the full-channel 2DCNN-LSTM model had good fitting capability and robustness (R2=0.74, RMSE=10.93), and further improvements were achieved after channel selection (R2=0.87, RMSE=6.84). The 10-fold cross-validation results indicated that the R2 between retrieval and measured values was above 0.85, the MAE was within 5.60, and the RMSE was within 7.90. R2 varied between 0.85 and 0.90, showing better validation at mid-day (R2=0.89) and in spring and fall transition seasons (R2 =0.88 and R2 =0.90). To investigate the cooperative effect of meteorological factors and other air pollutants on NO2, statistical methods (Beta coefficients) were used to test the factor interpretability. Meteorological factors as well as other pollutants were analyzed. From a statistical perspective, PM2.5, Boundary Layer Height, and O3 were found to have the largest impacts on near-surface NO2, with each standard deviation change in these factors leading to 0.28, 0.24, and 0.23 in standard deviations of near-surface NO2, respectively. Findings of the study contribute to a comprehensive understanding of the spatiotemporal distribution of NO2 and provide a scientific basis for formulating targeted air pollution policies.

Published: August 2023

Vaccines are an important tool of preventive medicine. Organized vaccination programs have saved numerous people from serious infectious diseases. Surprisingly, there is a considerable portion of the population who oppose vaccinations. In particular, the existence of anti-vaccination perceptions among travelers to countries with endemic diseases is a major public health concern. Although hesitancy towards vaccinations is not a novel phenomenon, it came back to the forefront during the fight against the COVID-19 pandemic. This review explored the etiology of anti-vaccination beliefs among travelers and drew conclusions about their impact on public health and society in general. For this purpose, a purposeful search for data on the causative factors of vaccine hesitancy and their impact on people’s health was conducted. A descriptive analysis of the findings and conclusions about possible implications in health policy and clinical practice are presented. Fear of side effects, lack of credence in the necessity of vaccines, and mistrust of medical authorities are important causative factors. Their interplay shapes hesitancy towards vaccines. However, anti-vaccination beliefs can also be an aspect of a more general unconventional stance of life. Health care professionals and organizations must be ready to tackle vaccine hesitancy by making the necessary interventions. Correcting misconceptions about vaccinations is a prerequisite for ensuring personal and public health, especially in the context of a pandemic or epidemic. Moreover, ensuring the efficacy and safety of vaccines, especially in cases of modern technology applications, is a fundamental factor in addressing people’s concerns about vaccines. For this purpose, medical authorities and organizations must provide accurate and clear information on vaccines so as to eliminate misinformation. Furthermore, clinicians should cultivate their communication skills in order to convey the appropriate messages to prospective recipients of vaccinations.
The Effects of Fairness Concern and Corporate Social Responsibility on Bilateral Quality Efforts of Agricultural Products Supply Chain
Authors: Qin Yanhong , Xiang Lin
Published: August 2023

This study takes a two-echelon agricultural products supply chain (APSC) composed of an agricultural product processor (processor) and an agricultural product supermarket (supermarket) as the research object. In order to ensure the stable supply of high-quality agricultural products, this paper considers both fairness concern and corporate social responsibility (CSR), and establishes four Stackelberg game models with or without considering fairness concern and CSR, and obtains the influence mechanism of fairness concern and CSR on bilateral quality efforts in APSC through comparative analysis and numerical analysis. Research shows that the supermarket’s fairness concern can take the role of "profit distribution mechanism", but it is not conducive to improving bilateral quality efforts resulting in the inability to improve market demand, and it is not conducive to improving the utility of the supply chain system and consumer surplus; both members of APSC sharing CSR can not only improve the quality of agricultural products and promote the expansion of market demand, but also can achieve Pareto improvement of both profit of all members and supply chain system. Besides, The CSR shared by both members has a greater impact on bilateral quality efforts decision than the supermarket’s fairness concern, and thus the positive effect of CSR can overcome the negative effect of supermarket’s fairness concern.
Default Probabilities and the Credit Spread, Modified Merton model, Mexican Case
Authors: Morales-Bañuelos Paula , Fernández-Anaya Guillermo
Published: August 2023

This study aims to identify the model that best approximates the credit spread that should be fixed on debt instruments issued by both public and private companies, considering the particularities of the Mexican market. Five models were analyzed: Merton's [1], those proposed by Denzler et al., the one presented in this paper, which includes the conformable derivatives, taking as a reference the change of variable made by Morales-Bañuelos et al., and the Corporate Default Risk Model (DRSK) for Publics Firms of Bloomberg [4].
The required financial information was obtained from the Bloomberg platform, from which the probabilities of default, credit spreads, and credit ratings for each company in the sample under the model (DRSK) were extracted directly. Likewise, the program developed by Moody's K.M.V. was used to obtain the EDF (Expected Default Frequencies). It was concluded that the Modified Merton model approximates to a greater extent the credit spreads that fix on a prime rate on the loans granted to the Mexican non-financial companies.

Published: August 2023

Printed oral splints are a therapeutic alternative in the treatment of functional disorders. Their mechanical properties are crucial to their clinical success and their performance can vary depending on cleaning, post-polymerization, or build orientation. This in vitro study aimed to compare the biaxial flexural strength of the chosen materials depending on the aforementioned parameters. 720 discs (n = 15 per group, 16 mm x 2 mm) were printed from splint materials. Printing was performed under 90°, 45°, or 0° orientation to the building platform with supporting structures. Specimens were either automatically or manually cleaned with isopropanol. Post-polymerization was performed with LED- or Xenon-light. Biaxial flexural strength (BFS) was determined with a piston-on-3-ball test after 24 hours or 60 days water storage (37°C). Test specimens were preloaded with 0.5 N and the load was applied by a piston of 1.6 mm in diameter at 1 mm/min crosshead speed. Statistics were performed by using descriptive statistics, ANOVA, and Levene-tests. Mean BFS after 24 hours of storage varied between 79 MPa and 157 MPa. After 60 hours the BFS significantly decreased and revealed values ranging from 72-127 MPa (mean24 113 MPa, mean60 97 MPa; p<0.001). No significant differences could be determined between the materials (p=0.103) or between the different cleaning procedures (p=0.321). Post-polymerization yielded higher means with LED- (P1: 115 MPa) than with Xenon-light (P2: 95 MPa; p<0.001). Regarding position, the mean values ranged from 101 MPa for 0°, 102 MPa for 45°, and 115 MPa for 90°, which was significantly different (p<0.001). Build orientation of 90° and post-polymerization with LED-light provided significantly higher biaxial flexural strength and should be used to guarantee optimal strength of splint materials. Aging decreased the biaxial flexural strength of the tested specimens.
