Anthropological dimensions of modern educational culture: theoretical analysis

This research article concerns the anthropological dimensions of modern educational culture, offering a comprehensive theoretical analysis that uncovers the intricate interplay between culture, society, and education in contemporary contexts. Drawing on anthropological frameworks, the study explores how cultural beliefs, values, norms, and practices permeate educational systems, pedagogical approaches, and the experiences of learners. Through an examination of diverse cultural contexts, the research illuminates the profound influence of culture on educational practices and outcomes. The theoretical analysis underscores the significance of recognizing cultural diversity within educational settings, emphasizing the need for culturally responsive approaches to teaching and learning. It highlights the role of education as a dynamic, culturally embedded process that evolves in tandem with societal changes. Additionally, the research offers insights into the ways in which education can serve as a vehicle for cultural preservation, adaptation, and the empowerment of individuals within their respective cultural milieus. Ultimately, this theoretical exploration of the anthropological dimensions of modern educational culture contributes to a deeper understanding of how culture shapes education and, conversely, how education can impact and transform culture. The findings underscore the importance of cultural sensitivity, inclusivity, and global awareness in fostering educational environments that reflect the rich tapestry of human cultural diversity in today\u27s interconnected world

Recurrent Ectopic Pregnancy After Ipsilateral Segmental Salpingectomy

SummaryObjectiveWe report an unusual case of recurrent ectopic pregnancy in the distal remnant after partial salpingectomy.Case ReportA 23-year-old woman underwent laparoscopic right partial salpingectomy because of right tubal pregnancy. She returned to our hospital 2 years later with a positive pregnancy test and lower abdominal pain. Transvaginal ultrasonography revealed no intrauterine gestational sac but a right adnexal mass measuring 2.4×2.3 cm. The serum β-hCG (β subunit of human chorionic gonadotropin) level was 2,91 8.06 mlU/mL. Videolaparoscopy was performed, and an ectopic pregnancy in the distal remnant of the right fallopian tube was identified. Right salpingectomy was effective and the pathologic report confirmed the diagnosis. The patient's postoperative recovery was uneventful.ConclusionIf conservative methods are not suitable for a patient with tubal pregnancy, total salpingectomy is the preferred option over partial salpingectomy. A remnant poses a risk for recurrent ectopic pregnancy owing to potential transperitoneal migration of either embryos or sperms. [Taiwan J Obstet Cynecol 2008;47(2):203-205

Generational Differences in Household Car Ownership

The stagnation of car demand had been observed in many countries. A similar phenomenon had emerged in Taiwan. From the perspective of socio-demographic characteristics, this study employs quantile regression for count data to investigate generational differences in household car ownership in Taiwan. The results show that the socio-demographic characteristics affected household car ownership. Due to the seniority effects, households in the later life-cycle stages and households with a higher proportion of elderly members would reduce car demand. But, households with the middle-aged heads owned more cars due to their better economic ability. The income effects are greater for higher income households. Household car ownership varied across generations, which was related to the income effects, the life course, and household structure. Hence, the demographic changes and generational differences in travel preferences should be considered in urban transportation planning. Seamless transportation and senior-friendly facilities would be important for transportation demand management

Price of Stability in Quality-Aware Federated Learning

Federated Learning (FL) is a distributed machine learning scheme that enables clients to train a shared global model without exchanging local data. The presence of label noise can severely degrade the FL performance, and some existing studies have focused on algorithm design for label denoising. However, they ignored the important issue that clients may not apply costly label denoising strategies due to them being self-interested and having heterogeneous valuations on the FL performance. To fill this gap, we model the clients' interactions as a novel label denoising game and characterize its equilibrium. We also analyze the price of stability, which quantifies the difference in the system performance (e.g., global model accuracy, social welfare) between the equilibrium outcome and the socially optimal solution. We prove that the equilibrium outcome always leads to a lower global model accuracy than the socially optimal solution does. We further design an efficient algorithm to compute the socially optimal solution. Numerical experiments on MNIST dataset show that the price of stability increases as the clients' data become noisier, calling for an effective incentive mechanism.Comment: Accepted to IEEE GLOBECOM 202

Effects of polymer additives in the bulk of turbulent thermal convection

We present experimental evidence that a minute amount of polymer additives can significantly enhance heat transport in the bulk region of turbulent thermal convection. The effects of polymer additives are found to be the \textit{suppression} of turbulent background fluctuations that give rise to incoherent heat fluxes that make no net contribution to heat transport, and at the same time to \textit{increase} the coherency of temperature and velocity fields. The suppression of small-scale turbulent fluctuations leads to more coherent thermal plumes that result in the heat transport enhancement. The fact that polymer additives can increase the coherency of thermal plumes is supported by the measurements of a number of local quantities, such as the extracted plume amplitude and width, the velocity autocorrelation functions and the velocity-temperature cross-correlation coefficient. The results from local measurements also suggest the existence of a threshold value for the polymer concentration, only above which can significant modification of the plume coherent properties and enhancement of the local heat flux be observed. Estimation of the plume emission rate suggests that the second effect of polymer additives is to stabilize the thermal boundary layers.Comment: 8 figures, 11 page
