En gymnastförening för facklig kamp. Föreningen GCI 1902–1950
Authors: Bolling Hans
Published: October 2023

This article deals with the activities within the Association GCI during the first half of the 20th century. The association was formed in 1902 by female graduates of the Royal Central Institute of Gymnastics (GCI) to promote their interests. The study is primarily based on the association’s yearbooks and daily newspapers. The study’s three main research questions are: Why was the Association GCI formed? Who was behind the formation? What results did the association achieve or not? The association’s most important contribution during the period was its courses for gymnastics directors, which were characterized by both curiosity and boldness. The conservatism regarding physical culture that is otherwise often associated with GCI was not present here. Nevertheless, in the long run, the association did not succeed in strengthening the members’ professional positions. In conflicts with the medical profession and the Gymnastics Teachers Association, the Association GCI drew the shortest straw.

Authors: Wang Zhan
Published: October 2023

Acquiring innovative styles and compositions from intricate and heterogeneous artistic imagery has emerged as a pivotal research quandry within contemporary new media art image conception. In a concerted effort to adeptly distill the quintessence of artistic styles and elements embedded within these visuals, an innovative methodology is posited herein, underpinned by an enhanced U-net segmentation framework and harmoniously fused with the surface extraction image reconstruction algorithm. This meticulous amalgamation endeavors to attain accurate segmentation and tridimensional reconstruction of the artistry encapsulated in these images. Primarily, the imagery is meticulously partitioned, culminating in an output that artfully encapsulates the inherent artistic attributes. Subsequently, this segmentation outcome is adeptly reconstituted, bestowing form to a three-dimensional artistry model. Empirical validation substantiates the efficacy of this approach, with the method’s Mean Intersection over the Union (MIoU) parameter yielding an impressive score of 0.939 in segmentation performance. Moreover, the peak signal-to-noise ratio and structural similarity attain commendable zeniths of 38.16 and 0.9808, respectively, underscoring the excellence of the reconstruction process. The proposed methodology demonstrates its prowess in exacting segmentation and comprehensive reconstruction of semantic intricacies and nuanced features pervading the realm of artistic imagery. Consequently, this novel methodology augments artists’ capacity to discern diverse artistic paradigms and fabricate superlative new media art compositions of heightened caliber.

Published: October 2023

Head lice (Pediculus humanus capitis) are a major global concern, and there is growing evidence of an increase in head lice prevalence among Saudi schoolchildren. The purpose of this study is to investigate the prevalence of an insecticidal resistance mutation in head lice collected from schoolchildren. A polymerase chain reaction (PCR) was used to amplify a segment of the voltage-gated sodium channel gene subunit to assess the prevalence and distribution of the kdr T917I mutation in head lice. Subsequently, the restriction fragment length polymorphism (RFLP) patterns revealed two genotypic forms: homozygous-susceptible (SS) and homozygous-resistant (RR). The results showed that 17 (37.80%) of the 45 samples were SS, whereas 28 (62.2%) were RR and T917I and L920F point mutations were found in the nucleotide and amino acid sequences of RR. Compared to other nations, the frequency of permethrin resistance mutation in the head louse population in Saudi Arabia was low. This study provides the first evidence of permethrin resistance mutation in human head lice in Saudi Arabia. The findings of this study will highlight the rising incidence of the kdr mutation in head lice in Saudi Arabia.
Using sentinel nodes to evaluate changing connectivity in a protected area network
Authors: O’Brien Paul , Carr Natasha , Bowman Jeff
Published: October 2023

It has been recognized that well-connected networks of protected areas are needed to halt the continued loss of global biodiversity. The recently signed Kunming-Montreal biodiversity agreement commits countries to protecting 30% of terrestrial lands in well-connected networks of protected areas by 2030. To meet these ambitious targets, land-use planners and conservation practitioners will require tools to identify areas important for connectivity and track future changes. In this study we present methods using circuit theoretic models with a subset of sentinel park nodes to evaluate connectivity for a protected areas network. We assigned a lower cost to natural areas within protected areas, under the assumption that animal movement within parks should be less costly given the regulation of activities. We found that by using mean pairwise effective resistance (MPER) as an indicator of overall network connectivity, we were able to detect changes in a parks network in response to simulated land-use changes. As expected, MPER increased with the addition of high-cost developments and decreased with the addition of new, low-cost protected areas. We tested our sentinel node method by evaluating connectivity for the protected area network in the province of Ontario, Canada. We also calculated a node isolation index, which highlighted differences in protected area connectivity between the north and the south of the province. Our method can help provide protected areas ecologists and planners with baseline estimates of connectivity for a given protected area network and an indicator that can be used to track changes in connectivity in the future.
Análisis del efecto de la regulación sobre la innovación en el transporte público y sobre la frecuencia y tamaño de buses
Authors:   , Huerta González Vicente Ignacio
Published: October 2023

En distintas ciudades del mundo los sistemas de transporte público son operados por empresas privadas. En estas, el marco regulatorio es variado, sin embargo, es un resultado generalizado la dificultad que la introducción de mayor iniciativa privada logre aumentar la partición modal de este. En consecuencia, para buscar cómo la innovación puede ayudar a hacer más atractivos estos sistemas, esta tesis estudia los efectos de la regulación sobre la innovación. Para este fin, se analizó la experiencia en Santiago de Chile desde 1973 al presente contrastando las capacidades de innovar de los distintos actores. El objetivo es entender la brecha entre innovación potencial y práctica de autoridades y operadores. Las principales fuentes son la literatura, los contratos y leyes mismas y una serie de entrevistas semi-estructuradas a operadores de Transantiago. La innovación mostró ser dependiente del esquema regulatorio en el que la operación está inmersa. Ambos, autoridades y operadores, mostraron la existencia de innovative capabilities en la práctica, dependientes de los incentivos generados por el esquema regulatorio de cada etapa reconocida. El diseño institucional del transporte público sugiere ser un aspecto que realza la innovación de autoridades, la cual puede ser reflejada en inversión en infraestructura dedicada a buses. Respecto a la innovación relacionada con los vehículos, Transantiago fue la etapa más propensa a innovación, dado una mayor capacidad de inversión de los operadores como incentivos en renovación de la flota en los contratos. Dentro de las variables de servicios, se han mostrado bajos niveles de innovación en diseño de rutas desde la introducción de los esquemas licitados. Para profundizar este análisis, se establece un modelo teórico de los efectos de los esquemas de pago en la frecuencia y tamaño del bus, variables de servicio clave sobre las cuales el operador puede innovar. Las soluciones analíticas muestran que, como ocurrió con la experiencia de Transantiago, esquemas de pago basados en la oferta incentivan una mayor innovación frecuencia de buses y de menor tamaño, que un sistema de pagos fijos. Finalmente, la modelación ofrece una tarifa óptima teórica que incentiva a los operadores a proveer un nivel óptimo social de frecuencia y de tamaño de los buses para un cierto nivel de demanda.

Modelo para apreçamento de Fundos de Investimento em Direitos Creditórios (FIDCs)
Authors: Freund Alexius Viktor Andrade , Da Silva Antônio Carlos Magalhães
Published: October 2023

Este trabalho apresenta um modelo binomial, que utiliza o conceito de opções compostas, para apreçamento das diversas classes de cotas que compõem um Fundo de Investimento em Direitos Creditórios (FIDC). Diante de um setor com pouca liquidez, como é o caso do setor de securitização no Brasil, onde a pouca negociação de cotas não permite que o preço reflita de forma correta a percepção do mercado sobre as expectativas futuras envolvendo diversos fatores de risco, a questão do apreçamento se torna imprescindível para os agentes do mercado, como gestores, investidores e reguladores. Entretanto, não identificamos na literatura acadêmica, tanto internacional quanto nacional, um trabalho que utilizasse modelos de opções compostas e binomial no apreçamento de operações de securitização. Dessa forma, este estudo visa a contribuir com o mercado de securitização, ao desenvolver um modelo de apreçamento com flexibilidade para replicar as características específicas dos FIDCs, de modo a refletir com maior grau de realidade a estrutura do fluxo de pagamentos. Os resultados obtidos com o modelo foram aferidos, sendo comparados com outros modelos de apreçamento conhecidos da literatura acadêmica, e com um modelo de simulação, tendo sido considerados satisfatórios. O modelo foi então aplicado no apreçamento das classes de cotas de um FIDC com perfil específico, realizando-se, em conjunto, análise de sensibilidade de diversos fatores que poderiam influenciar nas rentabilidades dessas cotas.

The aim of the present study was to identify the structure of the bioactive molecules in the active ethyl acetate fraction of the hydroethanolic extract of Lecaniodiscus cupanoides (Sapindaceae), a Beninese plant used in the treatment of microbial infections. We prepared the hydroethanolic extract from powdered dried leaves. We fractionated the hydroethanol extract using the liquid-liquid extraction method with solvents of increasing polarity. The active ethyl acetate fraction obtained after bioguided fractionation of the hydroethanol extract on bacterial strains was purified by a series of atmospheric pressure column chromatographic methods coupled with thin layer chromatography. At the end of this purification process, three compounds, including a flavonoid and two fatty acids, were isolated and identified by interpretation of 1H NMR, 13C NMR and mass spectrometry spectra. These were: 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-2,3-dihydrochromen-4-one;(E)-3-(3,4-dihydroxyphenyl)-2-(3-(3,4-dihydroxyphenyl) acryloyloxy) propanoic acid and (E)octadec -9- enoic acid (oleic acid).

The added value of this work lies in the fact that these three molecules have never before been identified in this plant, and therefore represent a potential avenue for the development of a therapeutic arsenal to combat microbial infections.

Long Story Short, I Survived: An Exploration of the Meaning-making Stories of Suicide Attempt Survivors
Authors: Culajara Claire Lynn
Published: October 2023

This study aimed to explore how suicide attempt survivors construe meaning in their experiences. Using the case study approach by Robert Yin (2009), qualitative research was employed. Purposive and snowballing techniques were used to gather data from primary interviews, key informants, and psychological assessment tools. The analytic techniques were thematic and cross-case syntheses. The findings revealed the participants' earlier experiences such as relationship breakdowns and prior nonsuicidal self-injury behaviors were risk indicators of suicide attempt. However unique cases were due to same-sex attraction and gender identity issues. Protective factors included social support, effective control over situations, and reason for living. The study identified five themes of meaning-making: strengthening social connections, positive religious coping: a belief in the presence of a Higher Power (God), developing new perspective to life, value positioning on gratitude and grit, and optimism. The study highlights the importance of holistic approach that recognizes the physical, psychological, social, and spiritual aspects of suicide. This study has implications for families, social communities, practitioners and future researchers to investigate and broaden the breadth of these relationships for theory and practice. In conclusion, the urgency of this research stemmed from the need to address the rising global suicide rate and enhance suicide prevention efforts. By amplifying the perspectives of suicide attempt survivors and exploring the multifaceted nature of suicide, this research can be ultimately contributing to the preservation of lives and the reduction of the worldwide burden associated with suicide.

For beverage products, some analytical tests are conducted prior to packaging and distribution. However, physicochemical properties may affect product quality adversely in a number of ways. Liquids with high dissolved solids may impact inferior palatability and may induce an unfavorable physiological reaction in the transient consumer. In this study, it was to evaluate some certain physicochemical properties of syrup which was made from Juniperus excelsa’s berries collected from four different geographical locations managed by the Regional Directorate of Forestry authorities in Turkiye. Considerable physicochemical variations were found among Juniperus excelsa’s berry-based syrup products. The lowest value of pH: 5.46 was found with syrup prepared from Yalvaç-Isparta, (sample C), followed by pH: 5.75 from Hisarcık-Kütahya, (sample D), pH: 5.80 Ağlasun-Burdur (sample B), and pH: 6.32 Gazipaşa-Antalya (sample A), respectively.  However, syrup prepared from sample C showed the highest values of electrical conductivity (EC), total dissolved solids (TDS), sugar content (Brix), and also distinguished from the others by highest oxidation-reduction potential (ORP).  It was found to be 3136.1 uS/cm for EC, 1568 ppm for TDS, 1.90 °Bx for Brix and 188.6 mV for ORP. However, the highest turbidity value of 67.6 NTU was found with sample D while the lowest with sample A (39 NTU). These values may be good criteria for the botanical origin of syrup and therefore, it may be used in syrups prepared from Juniperus excelsa’s berries.

Published: October 2023

A stochastic differential equation (SDE) is a differential equation in which one or more of the terms and the solution are stochastic processes. Numerous studies have employed orthogonal polynomials, however most of them focus on deterministic rather than stochastic systems. This is the reason why in this study, we looked into a numerical solution for the stochastic Ito-Volterra integral equation using the explicit finite difference scheme and Bernstein polynomials as trial functions. The equidistant collocation procedure was used to calculate the unknown constant parameters in between and reach the desired approximation. The method was evaluated and contrasted with the Block Pulse method for approximate answers based on the aforementioned method, which were obtained and compared with others in the literature.
