Human Capital Productivity and "ageing" Expenditure: An OECD Study
Authors: ZAPJI YMELE Aime Philombe
Published: February 2024

Abstract

Demographic ageing that is already evident in many OECD countries will become more acute in the coming decades. The costs associated with this phenomenon are most apparent in spending on pensions, healthcare and long-term care. Among the solutions put forward to deal with this, the productivity of human capital is the one we propose and analyze. According to Mincer's theory, the salary, which represents the reward for production, is the variable that we propose to use in the analysis of human capital productivity. Salary is the materialization of work done, so the higher it is, the more productive it is. Salary variation is therefore our dependent variable and spending on pensions and healthcare are our key independent variables. Our analysis covers 33 of the 37 countries that make up the OECD system. We use the ordinary least squares method on panel data covering the period 2000-2020. Our key independent variables show a negative correlation with salary variation. This would mean that an increase in spending on pensions and healthcare would lead to a reduction in salaries to cover these costs. However, as our education variables (average years of study, employment rate of secondary and tertiary graduates...) show a positive correlation with salary variation, we can undoubtedly state that improving human capital through education and training is the solution to be encouraged by the public authorities in a context of ageing.

Determination of Scolytinae and Platypodinae (Coleoptera : Curculionidae) flight area using sticky traps
Authors:   , Paiola Gabriel
Published: February 2024

The flight behavior and related aspects of Scolytinae and Platypodinae are poorly known and are commonly studied with baited flight intercept traps with different models and designs, with trapping varying between their models. We built an ethanol-baited sticky window trap with concentric circles that simulates different sizes of panels of intercept traps, to determine how accurately the targeted beetles can find the attractant source. The traps were positioned at different angles in relation to the predominant wind direction, to establish if the beetles fly upwind while searching for the attractant. The sticky window trap was not adequate to define if the Scolytinae, Platypodinae, Bostrichidae and Cerambycidae fly upwin trying to reach the attractant source. Most beetles were more trapped in the periphery of the trap, and the wind modeling indicated that the wind in both sides of the trap spread out, likely dragging the ethanol to the edges of the trap, hence changing the shape of the attractant plume. Keywords: Ambrosia beetles. Trap efficiency. Upwind flight. Wind modeling.
Ação da isca à base de isocicloseram em colônias de Atta sexdens (L.)
Authors:   , Cruz Luana de Souza
Published: February 2024

As formigas-cortadeiras são pragas de difícil controle, pois são insetos sociais e possuem táticas de defesas e sistema de seleção dos vegetais que cortam. O uso de inseticidas, na atualidade, é a melhor alternativa no controle às formigas, apesar dos danos que potencialmente causam ao ambiente. Têm-se buscado o avanço de novos formicidas com objetivo de controlar esses insetos, reduzindo assim as perdas causadas por sua atividade forrageira, além de minimizar seus efeitos potencialmente adversos ao ambiente. O plinazolin, tem se mostrado uma alternativa potencial no controle de formigas-cortadeiras, demonstrando alta eficiência em estudos de campo, porém pouco se sabe sobre como este composto atua nas colônias de formigas-cortadeiras. Assim, o objetivo principal desse trabalho é elucidar como a isca à base de plinazolin atua em colônias de formigas- cortadeiras Atta sexdens e seus possíveis efeitos relevantes nas diferentes castas, desde efeitos letais a subletais. Além disso, avaliar a sobrevivência das operárias com dieta semi-sólida, contendo o ingrediente ativo. Além disso, avaliou-se consumo foliar, massa de lixo produzida, volume do jardim de fungo, sobrevivência das colônias e interações entre as castas. Os efeitos dessa isca foram comparados aos efeitos da isca comercial contendo sulfluramida e uma isca artesanal utilizada como controle. O plinazolin causou supressão das colônias ocasionando rápida mortalidade das operárias, comprometendo a vida da colônia. Além dos efeitos letais às formigas e colônias, o plinazolin foi disperso de forma igualitária entre as castas causando redução no consumo foliar e na massa lixo produzida pelas colônias em decorrência da rápida mortalidade das operárias. Do mesmo modo, a dieta semi-sólida com plinazolin afetou a mortalidade de todas as castas mostrando que o ingrediente ativo foi disperso de forma igualitária, ao contrário apresentou a sulfluramida que evidenciou mortalidade de jardineiras nos primeiros dias após exposição das iscas. Por outro lado, os resultados mostraram que o plinazolin desencadeou maior número de interação entre as operárias forrageadoras tratadas e não tratadas em relação a colônias não expostos a este composto. Assim, concluiu-se que a isca de plinazolin desencadeia supressão rápida das colônias ao afetar drasticamente todas as castas comprometendo todas as atividades do ninho, apesar de não comprometer o carregamento. Além disso, plinazolin também mostra efeito retardado em operárias forrageadoras não comprometendo o carregamento das iscas, mas subsequentemente interferindo em suas interações comportamentais e causando mortalidade destas. Tais efeitos comprometem a sobrevivência da rainha e da colônia. Palavras-chave: Atrativos. Controle químico. Toxicologia.
Insecticide resistance, genetic diversity, and ecological niche distribution associated with the co-occurrence of rice stink bugs in Neotropics
Authors:   , Vieira Juliana Lívia
Published: February 2024

Anthropogenic-mediated climate change generally favors the spread and establishment of species better adapted to warmer conditions, while global connectivity increases the likelihood of some species expansion. Additionally, agricultural ecosystems offer ample opportunities for pest species to settle due to the relative impoverishment of local native species and the high availability of resources for better- adapted herbivores. Neotropical rice fields and the rice stink bugs Oebalus poecilus and O. ypsilongriseus provide a scenario in which apparent area expansion and trade- offs are occurring, favoring the establishment of a species complex, and of which the belated perception of the problem could lay significant economic and management consequences. In light of the main aspects of O. poecilus and O. ypsilongriseus biology and management, the objective of this thesis is to understand the factors mediating the distribution and overlap of these species. For that, the levels of thiamethoxam insecticide resistance and control failure likelihood were geographically assessed, as were each species' genetic diversity and population structure, attempting to recognize their relative occurrence, potential prevalence, and the likelihood of range expansion. Furthermore, species distribution modeling was used to identify the main predictor variables for the rice stink bug's niche occurrence and overlap. Our findings revealed that resistance to the main insecticide used in their control, thiamethoxam, does not appear to be decisive in species differentiation and prevalence. Nor are genetic divergences found here, considering that both species presented similar levels of diversity and structuring. However, the phenotypic plasticity (or its limitation) expressed in the ecological niche of rice stink bugs appears to indicate that sensitivity to drier periods may be an essential component in the distribution and dominance of these species in Neotropical regions. Thus, by combining control failure likelihood estimates, insecticide resistance, and spatiotemporal dynamics, with population genetics and species distribution modeling, this study allows insights on the relative importance and potential impact of two closely-related species, which in turn could potentially minimize unsuitable pest management practices and rice production losses. Keywords: Genetic diversity. Insecticide resistance monitoring. Pest management. Species distribution modeling. Species overlap.

Facial Expressions as Behavioral Indicators for Assessing Pain using Machine Learning Models
Authors: Nath Uma
Published: February 2024

Pain is a symptom of a condition or disease. Pain experienced in the body is verbally reported to a health care giver. Currently there is no objective way to measure physical pain or discomfort one may be feeling. And so consequently, there is no way for caregivers to adequately assess patients in pain who cannot verbalize it, such as non-verbal, adult patients and young children. Facial expressions may be used as a behavioral indicator for evidence of pain which can then be used to communicate a patient's distress and pain severity. These facial expressions can be recognized through jaw clenching, eyebrow raising, and eye squinting. Machine learning with vision based algorithms may differentiate these behavioral face-indicators and assess the pain levels of nonverbal patients. There have emerged many vision based methods for predicting pain from face images. This review summarizes the development of pain recognition from facial expressive images or videos, datasets available for research, an overview of vision based methods using conventional and deep learning, the current challenges and limitations, and scope for improvement in future.

Authors: Saridena Abhaya , Saridena Ananya , Kethar Jothsna
Published: February 2024

One of the main causes of death worldwide is cardiovascular disease (CVD). Effective treatment of this global concern depends on early detection, as well as management. Currently, people with established heart issues are treated by physicians and other medical experts, with detection at later stages of CVD. However, the burden of cardiovascular disease treatment can be significantly reduced if it was possible to accurately estimate a patient's CVD risk at the initial stages. Machine learning techniques have emerged as a viable method for improving CVD risk prediction, which enables treatments to be more effectively tailored to each individual patient's needs. An in-depth analysis of current research on machine learning applications for CVD risk prediction is provided in this publication. The paper discusses the benefits of applying machine learning techniques, various prediction algorithms, performance assessment, and current research limits. Our findings suggest that machine learning methods are useful for predicting CVD risk and have the potential to improve clinical judgment, which may help to lessen the burden of cardiovascular disease in the future. This research also helps to shape the medical field by providing insights on treating similar deadly diseases using AI and machine learning models.

Published: February 2024

Cancer is the second leading cause of death worldwide and with the disease having over 200 variations, it has not been cured yet despite being the priority of the medical field for decades. Due to the difficulty of human subject research, animal studies, e.g., mouse and Chinese hamster V79 tumors have been widely used to test the modeling of tumor growth due to their dynamic nature and ability to grow to high volumes within short periods of time. Mathematical models, including ordinary differential equations (ODEs), have been utilized to model tumor growth and study treatment of cancer. With most current models being selected only for mathematical convenience, recent studies have been focusing on determining the optimal treatment schedule for the most popular existing treatments of chemotherapy and radiation therapy. In this paper, three of the most established ODE models: the Gompertz, Von Bertalanffy, and logistic models are utilized to analyze which model most accurately fits existing tumor growth data for the Chinese Hamster V79 fibroblast tumor, various forms of immunodeficient mice tumors, and glioblastoma based on the minimization of the normalized mean squared error (NMSE). Next, the ODEs themselves were modified to simulate the growth of the tumors when exposed to treatment and determined which treatment schedule produced the lowest final volume of the tumors. The results of this research identify the optimal treatment schedules based on data from all three ODE models and also determine the ODE models that produce curves that most precisely fit the datasets.

The Effect of Amyloid Beta on Symptoms Caused by Traumatic Brain Injury in Drosophila melanogaster
Authors: Valentini Katherine , Eliason Jessica
Published: February 2024

Traumatic brain injury (TBI) is the cause of one third of all injury-related deaths in the United States alone, and approximately 1.7 million people sustain a TBI each year. Depending on the severity of the, a TBI could lead to sustained damage to cognitive and locomotive abilities. Treatments for TBI have been previously investigated; however, prior research does not include the investigation of amyloid beta protein (Aβ), a protein found to accumulate rapidly after TBI, as having a role in recovery from TBI. This experiment focused on studying the effect of the presence of Aβ on cognitive and locomotor ability in Drosophila melanogaster after TBI. The cognitive and locomotor skills of D. melanogaster were tested through the means of a food-based choice assay and a climbing assay respectively. After data collection, Mann Whitney statistical tests were done between D. melanogaster groups to determine the significance of the results. From the statistical analysis of the results, the following was derived: the presence of Aβ is related to improved locomotion in D. melanogaster after TBI according to a significant difference in assay success rates between D. melanogaster with and without Aβ (p-value < 0.0001), however there was no demonstrated relation between Aβ and improved cognition (p-value = 0.0663). Therefore, the hypothesis regarding the possible neural repair properties of Aβ is partially supported. It can be concluded that while Aβ had no effect on cognition in D. melanogaster after TBI, its presence is directly related to the improvement of locomotion.
Cytogenetics and Molecular Diagnosis in Horse Infertility
Authors: Choi Jiwon , Cerna Mayra , Raupsepp Terje
Published: February 2024

As the popularity of horse breeding stays steady, many breeders and owners send their horses samples to cytogenetics analysis for signs of infertility or other genetic abnormalities. Here, we report three cases of horses that were subjected to chromosome analysis due to infertility issues. Unfortunately, in the case of the H304 mare, the horse has a normal 64, XX female karyotype and no chromosomal abnormality was observed to explain the infertile issue. In the case of the H305 mare, the horse has a 64, XY male karyotype which indicates genetically male and no sign of chromosomal abnormality under cytogenetic analysis. However, PCR analysis indicates the loss of the SRY in the Y chromosome. This is a typical male to female sex reversal and one of the most common genetic sex abnormalities in horses. In the H306 mare, the horse has only one X chromosome; 63, XO, called X monosomy. This is the most common sex chromosomal abnormality in horses. The combination of clinical cytogenetic analysis and the use of PCR are the strongest tool to determine the chromosomal abnormality in the equine industry and the case H305 is a good example to support how these two different approaches compensate each other to generate a reliable diagnosis. Determination of genetic abnormalities using two techniques will help horse breeders and equine practitioners to make the most informed decisions about breeding plans.

Self-Determination to Better Health Outcomes: A Study of Diabetes in the Native American Community
Authors: Echambadi Maya , John-Mariadoss Babu
Published: February 2024

Increased self-determination in health care by the Native American community may help combat preventable diseases like diabetes. The racial stereotyping of Native Americans in medical clinics has been found to directly correlate to health disparities such as poor care and poor medical outcomes (Solomon et al.). However, since 1975, the ISDEAA, or Indian Self-Determination and Education Assistance Act, provides three major avenues by which Native Americans may receive health care: directly from the federal government through the Indian Health Service, through a Title I contract to administer part of their own health care programs, or through a Title V compact to take over all of their own health care (Marley, “Ambiguous Jurisdiction” 433). Longitudinal research into the diabetes prevalence rates across time for each of the 574 federally recognized tribes should be juxtaposed against the timeline of when each individual tribe evolved from Indian Health Service dependent to Title I, and then finally to Title V. I had sought to prove that diabetes prevalence rates for Native Americans show a lagging decline as self-determination of health care increases. Further collection of specific, tribal, micro-level data is necessary to prove or disprove this point. Ultimately, this conceptual paper is a proposal for further data collection by the United States Department of Health and Human Services, which is in charge of the Indian Health Service.

In the pursuit of fostering workplace safety as an integral aspect of organisational vitality, present research delves into the landscape of safety performance within Small and Medium Enterprises (SMEs) in Malaysia. Despite facing resource constraints, the sector exhibit commendable dedication to safety, as evidenced by notably high levels of safety participation and compliance discovered among production workers through a cross-sectional study involving 107 professional respondents representing small and medium manufacturing firms in northern Malaysia. This study, addressing a crucial gap in research, sheds light on the need for continuous improvement strategies to sustain and amplify this positive safety culture within SMEs. The findings underline the significance of prioritizing safety initiatives, not only ensuring employee well-being but also fortifying the resilience and success of SME operations in Malaysia. Moving forward, it is imperative for these SMEs to invest in ongoing training programs and maintain open communication channels for safety concerns to further fortify their safety culture. Additionally, a longitudinal study could provide insights into the sustainability of these high safety performance levels over time, while exploring the impact of external factors on safety practices within these SMEs could offer valuable avenues for enhancing safety performance in the evolving business landscape.

The aim of the study is to examine the epistemological beliefs of preschool teachers and their proficiency in science activities in terms of some variables, and also to investigate the relationship between their epistemological beliefs and their proficiency in science activities. The population of the study consists of 213 preschool teachers working in public schools affiliated to the Ministry of National Education in the province of Gaziantep in the 2021-2022 academic year. The "relational screening model", which is one of the quantitative research models, was used in the study. In the thesis study, in addition to the personal information form containing some demographic information, two scales, "Scale for Determining Preschool Teachers' Competence in Science Activities" and "Epistemological Beliefs Scale", were chosen as data collection tools and SPSS 26 package program was used in the analysis of the data obtained from the measurement tool. With this research, statistical answers were sought to the main problem question and sub-problem questions determined in the study. According to the results obtained from the data analysis of the research, it has been determined that preschool teachers have developed/mature epistemological beliefs and their proficiency in science activities in line with these beliefs is high. These results show that preschool teachers are more efficient and competent in putting science activities into action when they search for knowledge, investigate how knowledge is obtained, add and apply their own interpretations. In addition to these results, as a result of the regression analysis, it was determined that epistemological beliefs predicted and explained their proficiency in science activities.
