Whole-Body Listening
Authors: Lanza Shannon , Lu Lin
Published: November 2024

Listening is a skill that serves as the foundation for all good communication. One of the most common scenarios encountered in child and adolescent psychiatry is one where a child verbalizes that their parent doesn’t listen, while the parent insists that they do. Whole-body listening is a framework that can be implemented by parents to engage in effective communication with their kids. Listening with the ears and eyes involves the utilization of verbal and nonverbal forms of communication. Listening with the heart involves showing compassion, while listening with the brain requires reading between the lines and understanding implied messages. Listening with the mouth involves reflective listening through speech to acknowledge a child’s point and provide validation and empathy. Finally, listening with the hands and feet involves following up words with actions. Each component of whole-body listening builds a tangible framework for children to identify elements of listening that parents might not execute well, and for parents to use to reflect and improve their listening with an end goal of prioritizing empathy over compliance and agreement.

Authors: Han Hongxia , Li Yuanwei
Published: November 2024

The diagnosis of ankle joint athletic injuries using traditional magnetic resonance imaging (MRI) relies on the subjective judgment and experience of doctors, and small structural changes in athletic injuries are difficult to accurately detect and diagnose. By using machine learning (ML) algorithms and image processing techniques to obtain objective and consistent diagnostic results, the accuracy of diagnosing ankle joint athletic injuries can be improved. This article collected a large number of MRI images of ankle joint athletic injuries, and preprocessed the collected images to extract morphological and texture features, and perform feature fusion. The Residual Network (ResNet) was improved, and the Leaky linear rectification function (ReLU, Corrected linear unit) activation function was introduced. The transfer learning was utilized to increase the convergence speed of the model, and the global maximum pooling layer and softmax classifier were used to construct the fully connected layer. After sufficient training on the training set, the findings on the test set indicated that the average accuracy of the improved ResNet model for ankle joint injury classification was 98.3%. The use of an improved ResNet model can effectively improve the diagnostic effectiveness of ankle joint athletic injuries, providing a new method for medical diagnosis of MRI.

Authors: Vasquez Lourdes Marcela Espinoza , Cedro Raul Rubin de Celis
Published: November 2024

This document aims to contribute to the understanding of the determinants for choosing the Economics career in Bolivia, as well as the impact that postgraduate education has on the salary levels of graduates in this field. Regarding the latter aspect, it seeks to test whether the number of years of study following the undergraduate degree of an economist determines a higher salary level and whether postgraduate studies serve as a signal of differentiation in the labour market. To achieve the objectives outlined in this document, various linear probability econometric models are employed, constructed from the results of a survey conducted in 2024 with 79 graduates and 45 students from the Economics program at the Universidad Católica Boliviana “San Pablo.” The results suggest that the choice of the Economics career is more likely influenced by close individuals rather than by the information provided by the University about the content of the program. Furthermore, a greater number of years of study after obtaining an undergraduate degree decreases the likelihood of achieving higher salary returns, indicating signs of adverse selection within the labour market for economists in Bolivia.

Published: November 2024

Purpose: The expected outcome of projects is to achieve a positive performance consistently. Yet, there is no agreed definition of project performance, which complicates the achievement of the purpose. Projects in Kenya are mostly complex and difficult to manage and project team management practices are mostly used in projects for effective functioning. However, project managers in Kenya have been focusing on technical constraints of projects and neglecting project teams’ related constraints. The objective of the study was to investigate the influence of project team rewards on project performance in commercial banks in Kenya.
Methods: The study adopted a pragmatic research approach. A cross-sectional study design and explanatory research design were adopted in the study. The unit of analysis was 429 projects in the 39 commercial banks operating in Kenya as of close of business on 31st December 2020 categorized into 20 types of Information technology projects. The target population was 195 Information Technology project managers as well as 78 staff working in human resource department, 78 staff working in finance department, and 78 staff working in operations departments in the 39 commercial banks operating in Kenya. The study used stratified random sampling to choose 206 respondents from the study population. Secondary and primary data was employed in this study. Annual reports of commercial banks provided secondary data. In addition, a semi-structured questionnaire was adopted to obtain data. Qualitative data, which was obtained from open-ended questions, was analyzed by use of thematic analysis, and the results were presented in a descriptive form. Inferential and descriptive statistics will be used to analyze quantitative data with the help of Statistical Package for Social Sciences (SPSS version 26). Descriptive statistics included frequency distribution, mean, standard deviation, and percentages. Inferential statistics included univariate regression analysis and Pearson correlation.
Results: The study found that project team rewards had a significant effect on performance of information technology-based projects in commercial banks in Kenya.
Conclusion: The study recommends that commercial banks should also diversify and strengthen their reward structures to better align with team members’ contributions and achievements. They should further strengthen their recognition and promotion programs to ensure that these elements are consistently applied and effectively contribute to team performance.
Drought resilience for Nicola River salmon
Authors: Chhor Auston
Published: November 2024

The summer of 2024 is shaping up to be one of the most devastating drought years in history. The province’s snowpack, which is the largest source of water in the summer, is on average 63% of normal levels, with some regions like Vancouver Island 46% of normal. Last summer, low rainfall records were set across the province, with many regions recording their driest summers in history. In BC, droughts are expected to get worse as a result of climate change as glaciers retreat, precipitation falls as rain in the winter instead of snow, and summer air temperatures rise. Using publicly available hydrometric and water licence data, we conducted an ecological audit of BC’s Water Sustainability Act to determine if current policies were adequately addressing drought in the semi-arid and highly agricultural Nicola basin. Our analysis determined that since the Act came into force, flows in salmon-bearing streams are consistently below the Critical Environmental Flow Threshold—the minimum amount of flow required to support salmon—during the summer spawning season. High water temperatures were also identified as a frequent occurrence. Our analysis of provincial water licence data also shows that just three larger users account for over half of all water use in the Nicola basin. Provincial water restrictions intended to protect fish populations during drought have only occurred twice in history, in 2009 and 2015, and were significantly delayed in their implementation. We offer eight policy solutions to improve outcomes for salmon during droughts.

Authors: González Rúa Juan Diego , Zuluaga Jaramillo Andrés Felipe
Published: November 2024

En este artículo se examinan las implicaciones del reconocimiento de los daños contra la naturaleza en el contexto de la justicia transicional, centrándose en el Informe Final de la Comisión de la Verdad elaborado en cumplimiento del "Acuerdo de Paz celebrado entre el Estado colombiano y las FARC-EP", específicamente desde su perspectiva ecológica. El enfoque propuesto por la Comisión ofrece elementos para avanzar en la consolidación de un giro eco-jurídico en la justicia transicional, permitiendo desafiar algunas de las tendencias antropocéntricas que tradicionalmente la han caracterizado. El informe reconoce el papel decisivo que la naturaleza no humana desempeñó en el desarrollo del conflicto armado, reivindicando su condición de víctima, y destaca la importancia de reparar los lazos socio-ecosistémicos dañados como condición necesaria para lograr una paz estable. El caso colombiano demuestra la necesidad de considerar las complejas relaciones humano-no humano en la explicación y resolución de conflictos sociales, así como en la construcción de una sociedad verdaderamente equitativa. A pesar de que el enfoque ecocéntrico del Informe representa un avance significativo en el ámbito de la justicia transicional, el artículo sugiere que la Comisión de la Verdad no alcanza a extraer todas las consecuencias de su propio enfoque desde el punto de vista de la justicia restaurativa ambiental.

Transcranial focused ultrasound (tFUS) possesses significant advantages such as non-invasiveness and high tissue penetration depth, making it a promising tool in the field of brain science. Acoustic holographic lenses can manipulate the sound field through phase modulation, providing a low-cost and convenient approach for realizing transcranial focusing. Acoustic holographic lenses have been successfully utilized for achieving precise transcranial focusing in living mice to open the blood-brain barrier and for performing neural modulation, which shows considerable application potential. However, existing transcranial acoustic holographic lenses can only be driven by specific ultrasound frequencies and focused at predetermined positions, which limits their flexibility in complex applications. To address this issue, this study establishes a multi-frequency transcranial focusing method based on acoustic holographic lenses to enhance its adaptability in the field of tFUS. By integrating acoustic holographic lenses designed for different focal positions at various frequencies, we generate multi-frequency acoustic holographic lenses suitable for transcranial focusing and conduct experiments to evaluate their performance. In simulations, for single-focus tasks, the peak signal to noise ratio(PSNR) of the proposed method achieves 32.16 dB under 1 MHz ultrasound excitation, and 40.18 dB and 2 MHz ultrasound excitation, respectively; for multi-focus tasks, the PSNR values are 29.39 dB and 39.89 dB, respectively. In experiments, for single-focus tasks, the PSNR value of the proposed method is 27.48 dB under 1 MHz ultrasound excitation, and 32.33 dB under 2 MHz ultrasound excitation, respectively; for multi-focus tasks, the PSNR values are 23.30 dB and 32.17 dB, respectively. These results demonstrate that the multi-frequency transcranial acoustic holographic lens can effectively modulate the sound field under varying ultrasound frequencies and create high-quality focal points at different locations behind the skull, which significantly enhances the application flexibility of transcranial acoustic holographic lenses.

This article presents a comprehensive study on the streamer propagation and electric field distribution within a two-dimensional fluid model of a packed bed reactor (PBR) filled with carbon dioxide, utilizing the PASSKEy simulation platform. The research delves into the spatiotemporal evolution of electron density, electric fields and key plasma species in the discharge process. The model simulates a PBR with layered dielectric spheres, indicates that the inner sides of the first and second layers of dielectric spheres are not the primary regions for reactions such as CO2 dissociation; instead, the main regions are along the streamer propagation path and the outer side of the first layer of dielectric spheres. The study by examining the propagation of streamers in the presence of an electric field, highlighting the influence of anode voltage rise and dielectric polarization on local electric field enhancement. This enhancement leads to increased electron density and temperature, facilitating streamer propagation and the formation of filamentary microdischarges and surface ionization waves. The article provides a detailed analysis of the local electric field evolution at specific points within the PBR. The research further investigates the spatiotemporal dynamics of spatial and surface charges, revealing that negative charges concentrate within the streamer and on the dielectric surface, with densities significantly higher than positive charges. The positive charges' distribution is closely related to the streamer's path, and over time, they come to dominate the charge distribution in the discharge space. The study also explores the surface charge deposition on the dielectric spheres, discusses the evolution trends of the distribution. Additionally, the article discusses the temporal and spatial evolution of key plasma species, including ions and radicals, and their contribution to the overall discharge characteristics. The production mechanisms of carbon monoxide particles, carbon dioxide ions, and oxygen ions are analyzed, with a focus on their spatial distribution and correlation with electron density. The study concludes with an examination of the energy deposition within the PBR, integrating the spatial energy deposition of electrons and major positive ions. The results indicate a total energy deposition value of approximately 1.428 mJ/m, with carbon dioxide ions accounting for 8.8% of this value.
Unraveling intrinsic relationship of thermal properties in thermoreflectance experiments
Authors: Chen Tao , Jiang Pu-Qing ,   School of Energy and Power Engineering, Huazhong University of Science and Technology, Wuhan 430074, China
Published: November 2024

Thermoreflectance techniques, particularly frequency-domain thermoreflectance (FDTR), play a crucial role in measuring the thermal properties of bulk and thin-film materials. These methods precisely measure thermal conductivity, specific heat capacity, and interfacial thermal conductance by analyzing the surface temperature response signals through thermoreflectance. However, the complex interplay among parameters presents challenges in data analysis, where single-variable analysis often fails to accurately capture intra-layer and inter-layer interactions. In this work, FDTR is used as a case study and the relationships between sensitivity coefficients of various parameters are systematically explored through singular value decomposition (SVD). Specifically, the SVD of sensitivity matrix  S  of the system's parameters is performed to identify smaller singular values and their corresponding right singular vectors, which are the basis vectors of the null space of matrix  S . These vectors reveal the relationships among parameter sensitivities, thereby uncovering the most fundamental combination parameters that determine the thermoreflectance signal. This method not only clarifies the dependency relationships between variables but also determines the maximum number of parameters that can be experimentally extracted, and the parameters that must be known beforehand. To demonstrate the practical value of these combination parameters, this work conducts a detailed analysis of FDTR signals from an aluminum/sapphire sample. Unlike traditional FDTR experiments, which typically fit only the thermal conductivity and interfacial thermal conductance of the substrate, our sensitivity analysis reveals that it is possible to simultaneously determine the thermal conductivity of the metal film, substrate’s thermal conductivity, substrate’s specific heat capacity, and interfacial thermal conductance. The fitting results are consistent with reference values from the literature and measurements from other thermoreflectance techniques, thus validating the effectiveness and reliability of our method. This comprehensive analysis not only deepens the understanding of thermoreflectance phenomena but also provides strong support for the future development of thermal characterization technology and material research, showing the significant potential application of SVD in complex multi-parameter systems.

Esta proteína es esencial para el desarrollo temprano del cerebro y la función neuronal.El paciente, un niño de siete años, comenzó a presentar movimientos distónicos de las manos a los 14 días de vida. A los seis años, se le diagnosticó retraso en el neurodesarrollo, hipotonía generalizada, episodios frecuentes de apnea y dificultad para la deglución.Aunque inicialmente se consideraron otras condiciones, como la distrofia muscular de Duchenne y la lipofuscinosis ceroidea neuronal, la secuenciación completa del exoma reveló la variante patógena c.692T>C (p.Phe231Ser) en el exón 1 del gen PURA, no registrada previamente en otros pacientes. Este hallazgo permitió un enfoque de manejo integral, con el cual se abordaron las características y alteraciones clínicas del paciente.Dado que el síndrome PURA no figura en la lista de enfermedades huérfanas o raras reconocidas por el Ministerio de Salud y Protección Social de Colombia, este reporte podría influir en su reconocimiento oficial.El caso demuestra la importancia de considerar diagnósticos raros en pacientes con síntomas neurológicos poco comunes y subraya la utilidad de la secuenciación genómica para el diagnóstico. Además, enfatiza la necesidad de colaboración en el área de la salud para optimizar el cuidado de los pacientes con síndrome PURA y otras enfermedades semejantes.

Introduction: The contribution of tubal factors to infertility is up to 30%. One of the tests used to evaluate tubal factor infertility is Doppler saline Sonosalpingography (SSG). The basic principle of SSG is to distend the uterine cavity with isotonic saline, which helps identify the uterine contour, intrauterine pathology, endometrial thickness and the presence of fluid in the Pouch of Douglas (POD). Adding Doppler increases its efficiency and accuracy. Aim: To ascertain the role of Doppler saline SSG in tubal infertility. Materials and Methods: This cross-sectional study was done for 18 months in the Obstetrics and Gynaecology Department of Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India involving 200 women with either primary or secondary infertility. These women were recruited in the midfollicular phase after obtaining written informed consent. Patients underwent Doppler SSG to assess tubal patency and the findings were compared with Diagnostic Hysterolaparoscopy (DHL). Diagnostic tests were used to calculate sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV). Inter-rater kappa agreement was used to find out the strength of the association between Doppler Saline SSG and diagnostic laparoscopy. A p-value of less than 0.05 was considered significant. The data was entered into an MS Excel spreadsheet and analysis was done using the licensed version of Statistical Package for Social Sciences (SPSS) version 21.0. Results: The mean age and mean duration of infertility were reported to be 29 years and five years, respectively. The sensitivity of Doppler SSG for tubal patency was reported as 85.4%, the specificity as 95.8%, PPV as 95.3%, NPV as 86.8% and the accuracy for tubal patency was 90.6%. Doppler SSG and laparoscopic chromopertubation findings had substantial association (k value -0.62). Conclusion: Doppler SSG is a reliable method for the assessment of tubal factors and can be used as a screening modality with high sensitivity and specificity.
Personalized Ketogenic Diet Using AI for Optimal Brain Health

The ketogenic diet (KD) has demonstrated potential for treating neurological conditions like epilepsy, Alzheimer's disease, and cognitive decline as well as for enhancing brain health. Individual reactions to KD, however, differ because of things like lifestyle, metabolism, and heredity. It is difficult to achieve the best results with a one-size-fits-all dietary strategy because of this diversity. A new answer is provided by artificial intelligence (AI), which makes it possible to provide individualized nutritional advice that take individual characteristics into consideration. AI-driven models can forecast a person's reaction to KD and customize macronutrient ratios, calorie intake, and micronutrient supplementation by combining data from genomes, metabolomics, and clinical profiles. This individualized strategy can boost mitochondrial function, lower inflammation, increase neuroprotective advantages, and enhance cognitive function. This study investigates the application of AI to create a customized ketogenic diet that maximizes brain function.

The present study entitled “Evaluation of Growing Media and Dormancy Breaking Chemical on the Seedling Growth of High Chill Peach” was conducted at Dept. of Horticulture, College of Agriculture and Horticulture Research Centre, G.B.P.U.A&T, Pantnagar, Uttarakhand during the year 2022-23. The experiments were carried out in Factorial Complete Randomized Design (FCRD) with 3 replications per treatment. Under seedling growth studies, the total numbers of treatment were 16 with 2 factors comprising of four growing media (soil: sand: FYM, soil: sand: vermicompost, soil: sand: cocopeat and soil: FYM: vermicompost: cocopeat) and four chemical treatments (control, GA3 @ 500 ppm, kinetin @ 50 ppm and thiourea @ 5000 ppm). In the experiment the maximum seedling length, shoot fresh weight, shoot dry weight, root length, root fresh weight and root dry weight was recorded in soil: FYM: vermicompost: cocopeat, GA3 @ 500 ppm and interaction M4C3 (soil: FYM: vermicompost: cocopeat + GA3 @ 500ppm) while the minimum values were recorded in soil: sand: cocopeat, control and M3C1.  Result from this study discovered that GA3 @ 500 ppm along with the growing media soil: FYM: vermicompost: cocopeat recorded the maximum seedling length, diameter, number of leaves, leaf area, shoot fresh weight and shoot dry weight which can be recommended for raising the rootstocks for the production of quality planting material of peach for seedling rootstock.

Balanites roxburghii (Linn.) species has been classified under the category of endangered plant species due to excessive exploitation for a variety of purposes, which has necessitated conservation of this tree species, and hence a study was conducted to investigate the effect of potting mixture and sowing orientation on early growth performance and vigour. Seeds were subjected to seven potting mixtures: M1: Soil:Sand:FYM 2:1:1, M2: Soil:Cocopeat:FYM 2:1:1,M3: Soil:Cocopeat:Vermicompost 2:1:1, M4: Soil:Paddy Husk:FYM: 2:1:1, M5: Soil:Paddy Husk:Vermicompost: 2:1:1, M6: Soil: Saw Dust:FYM 2:1:1, and M7: Soil:sawdust: Vermicompost 2:1:1. The seeds were sown in three orientations. S1: Seeds laid vertically with stalk end downwards; S2: Seeds laid horizontally and S3: Seeds laid vertically with stalk end upwards. Physiological parameters considered for assessment were seed germination, days taken for germination, seedling length, and seedling vigor index. A completely randomized design was used for the experiment. The results showed that there is a significant difference among seven different potting mixtures and three orientations. At the end of 8 weeks, the seed is sown horizontally in the potting mixture Soil:cocopeat:vermicompost (2:1:1) has recorded the germination percentage of 71.67%, 37 days taken for seed germination, highest seedling length (64 cm), and highest seedling vigour index (4561). The high-vigor seedlings may survive even in unfavorable conditions, with high survival rate compared to others. The study recommended that to obtain high-vigor Balanites roxburghii seedlings, seeds may be sown in potting mixture soil: cocopeat: vermicompost (2:1:1) with horizontal orientation.
