Published: November 2023

Seit der Einführung des Hochschulförderungs- und -koordinationsgesetzes (HFKG) existieren in der Schweiz Pädagogische Hochschulen, die neben Lehre, Forschung und Entwicklung auch Weiterbildungen und Zusatzausbildungen anbieten. Der Auftrag des HFKG führte zu einem doppelten Kompetenzanspruch. Aufgrund mangelnder Untersuchungen hinsichtlich dieses doppelten Kompetenzanspruchs im Fachbereich der Sportdidaktik wurde die subjektive Wahrnehmung von Dozierenden untersucht. Die Ergebnisse zeigen, dass mehrere Kompetenzansprüche wahrgenommen werden und unterschiedliche Kompetenzprofile vorliegen.
Assessing Land Use and Land Cover (LULC) Change and Factors Affecting Agricultural Land: Case Study in Battambang Province, Cambodia
Authors: Sourn Taingaun , Pok Sophak , Chou Phanith , Nut Nareth , Theng Dyna , Hin Lyhour
Published: November 2023

This study analyzed land use and land cover (LULC) change from 1998 to 2018 in Battambang, Cambodia, and determined factors and constraints affecting agricultural production. Landsat satellite images in 1998, 2008, and 2018 were used to identify the changes in LULC. In combination, a social survey was conducted in August 2021 using purposive sampling, selecting a total sample of 200 from two wealth classes: the poor (65) and the better off (135) based on the Cambodia poverty assessment by the World Bank, from uplands to lowlands of Battambang Province, Cambodia. Household characteristics, farm size, and constraints were compared between the classes. T-tests, the analysis of variance (ANOVA), and Likert scale analysis were adopted using the R Program and RStudio, while Pearson's correlation test was used to determine the factors affecting agricultural land. The results show that between 1998 and 2018, the forest cover decreased by 79%. In contrast, agricultural land expansion was the highest (54%). The average household size and age of the respondents were 5.0 persons/household and 50.1 years, respectively. Of all the interviewees, about 80% attended no higher than primary school. The total farm size of the better-off (7.0 ha/household) was larger than that of the poor (5.2 ha/household). The population growth, machinery use, and improved infrastructure were found to be positive and strongly related to agricultural land use. The highest constraints of the poor and the better-off households were the same: chemical fertilizer use. Then, drought and flooding were also challenges for all. In terms of land, credit, and labor, they were not the main constraints. Thus, it is recommended that the involvement of interdisciplinary stakeholders and policy frameworks is really important from both biophysical and social perspectives.
2022 socioeconomic research of Capitol Reef National Park: Report on 2022 data collection
Authors:   Otak, Inc.,   RRC Associates,   University of Montana
Published: November 2023

A strong mandate and need for socioeconomic monitoring are expressed in the NPS strategic goals for science, in statements by the NPS leadership, and the report of the Second Century Commission. This mandate resulted in a pilot socioeconomic monitoring study in 2015/2016 at a sample of park units across the U.S; the current study uses outcomes from the first stage of the pilot program and progresses into a second stage of the pilot process at 24 NPS units across the United States. Capitol Reef National Park (Capitol Reef) was selected as one of these units. This report informs core issues of visitor use management and develops a deeper, contemporary understanding of who visits Capitol Reef and what they do during their visit. It uses a two-phased survey methodology to capture a representative sample of visitor information, characteristics, and behavior: (1) an on-site intercept survey conducted via tablet, and (2) a follow up (mail-back and/or online survey) for full trip details. The results are organized by these two phases and are aimed to assist park managers in understanding current utilization and perception of park resources, operations and potential issues, as well as facilitating communication and decision-making processes within the park and between the park and its local partners and stakeholders.

Citizenship Under Pressure
Authors: Mordecai Rachel L.
Published: November 2023

Citizenship Under Pressure: The 1970s in Jamaican Literature and Culture is the first book-length study of the interaction of culture, politics and society in Jamaica’s formative postcolonial moment, the years between 1972 and 1980. Through examining literary and other texts from and about the period, Rachel Mordecai argues that the 1970s were defined by the explosion into the public sphere of a long-simmering dispute over the substance and limits of Jamaican citizenship, in which citizenship claims and counter-claims were advanced and contested via the symbolic deployment and re-configuration of race, class, and gender identities.

Authors: Araujo Igor , Balogh József , Luo Haoran
Published: November 2023

Denote by $F_5$ the $3$-uniform hypergraph on vertex set $\{1,2,3,4,5\}$ with hyperedges $\{123,124,345\}$. Balogh, Butterfield, Hu, and Lenz proved that if $p > K \log n /n$ for some large constant $K$, then every maximum $F_5$-free subhypergraph of $G^3(n,p)$ is tripartite with high probability, and showed that if $p_0 = 0.1\sqrt{\log n} /n$, then with high probability there exists a maximum $F_5$-free subhypergraph of $G^3(n,p_0)$ that is not tripartite. In this paper, we sharpen the upper bound to be best possible up to a constant factor. We prove that if $p > C \sqrt{\log n} /n $ for some large constant $C$, then every maximum $F_5$-free subhypergraph of $G^3(n, p)$ is tripartite with high probability.

Authors: Kim Jinyoub , Moon Jisang , Do Yeji , Kim Hayul , Jeong Jongpil
Published: November 2023

A notion for a policy tool that is particularly supported in policy circles to support the circular economy is the digital product passport (DPP). To lay the groundwork for more circular products, the basic design of a DPP should primarily comprise product-related data gathered by manufacturers. This study aimed to look into the design options for a DPP system and how these options for a DPP system and how these options could help players in the EV battery market given the absence of scientific debate surrounding DPP. With a focus on the role of stakeholders, it does so while introducing the idea of DPP and outlining the current system of legal and voluntary product information instruments. These preliminary results are incorporated into an examination of the possible advantages of DPPs that is actor centered. Through desk research and stakeholder workshops, data is produced. We discovered a significant need for more research, in particular, by examining the function of the DPP system for various actors. These issues include how to reduce red tape and increase incentives for manufacturers to provide specific information, how pertinent data can be compiled, what data collection tools (such as databases), and to which stakeholder groups these data are made available. To give DPPs better policy direction, other researchers might be able to fill the research gaps identified in this work.

Authors: Wang Shuang , Shen Weiwei , Shen Chengjun , Li Xiang , Chen Hao , Feng Yongqiang , Hu Yamin , Qian Lili , Zhang Xuemin , Li Yinran
Published: November 2023

With the development of educational ideas, practical puzzles emerged as a new cultural vehicle and mode of education in recent times. Game teaching itself is full of interest, interaction and collaboration, which greatly benefits the development of self-directed learning of student interests. At the same time, with the deepening of curriculum reform in colleges and universities, according to the “Science, Technology, Engineering, Art, Mathematics” (STEAM) concept, practical puzzle games including board games combined with professional basic courses will give them educational and social values which also leads to a concept of “teach through lively activities”. From the perspective of teachers and students, the paper further improves the application of tabletop gaming education for the teaching of professional courses in colleges and universities. This improvement will be basically achieved by providing feedback on learning from three aspects: pre-class preview, in-class teaching, and after-class review.

Published: November 2023

La hemorragia obstétrica sigue siendo la causa principal de muerte materna en todo el mundo y se considera que más de la mitad de los casos de morbi- mortalidad grave por hemorragia son prevenibles. En los casos en que el desenlace fue la muerte materna, el diagnóstico y tratamiento se dieron de manera tardía; y la comunicación entre los equipos fue deficiente. La hemorragia obstétrica es considerada una emergencia y su incidencia varía según la adaptación de los protocolos de cada institución. Su reconocimiento temprano es crucial para brindar el soporte hemostático inmediato. Sin embargo, existe una falta de acuerdo respecto a las definiciones y manejo en las guías establecidas. Una definición clínica consensuada de la hemorragia obstétrica debe considerar el volumen de la pérdida de sangre, los signos vitales, los síntomas clínicos, la coagulación y los cambios o inestabilidad hemodinámica y en cuanto sea posible se debe ofrecer un tratamiento hemostático dirigido. Esta revisión tiene como objetivo puntualizar las recomendaciones de las nuevas guías clínicas sobre el manejo de la hemorragia posparto desde el rol del anestesiólogo y la implementación de las mismas en un caso de nuestra práctica clínica.

Authors: Efriani Like , Hadi Ismanurrahman , Irawan Ade , Ulfah Mariam , Adiyas Putra Teguh
Published: November 2023

Diabetes mellitus tipe II merupakan kelainan metabolik yang disebabkan karena ketidakmampuan pankreas untuk memproduksi insulin sehingga menyebabkan hiperglikemia. Akarbose menjadi salah satu obat dalam pengobatan dari diabetes mellitus dengan cara menghambat inhibisi enzim a-glukosidase. Tanaman mangrove (Rhizopora mucronata) diketahui mempunyai senyawa fitokimia dengan berbagai aktivitas farmakologis. Tujuan dari peneltian ini adalah untuk mendapatkan informasi aktivitas penghambatan enzim a-glukosidase dari ekstrak metanol, etanol, dan aseton daun mangrove. Penelitian ini dilakukan dengan memaserasi simplisia daun mangrove pada pelarut metanol, etanol, dan aseton. Maserat yang didapatkan, diujikan secara kualitatif untuk mengidentifikasi kandungan golongan senyawa alkaloid, flavonoid, saponin, dan terpenoid, lalu dilanjutkan dengan mengujikan inhibisi aktivitas dari enzim a-glukosidase dengan konsentrasi ekstrak 0,5; 1; 1,5; 2; dan 3 mg/mL menggunakan Microplate Elisa Reader dan dilanjutkan pengukuran absorbansi dengan spektrofotometer UV-Vis dengan panjang gelombang 405 nm. Hasil yang didapatkan menunjukkan maserat dari ketiga jenis pelarut tersebut terbukti memiliki kandungan senyawa golongan alkaloid, flavonoid, saponin, dan terpenoid. Uji aktivitas inhibisi menunjukkan aktivitas inhibisi dari ekstrak metanol (3,5 mg/mL), etanol (2,6 mg/mL), dan aseton (2,1 mg/mL). Ekstrak aseton memiliki aktivitas inhibisi paling baik karena semakin kecil nilai IC50 maka semakin baik aktivitas inhibisi pada enzim a-glukosidase. Berdasarkan hal tersebut, dapat disimpulkan bahwa ekstrak aseton mangrove memiliki aktivitas inhibisi paling baik dibandingkan kedua ekstrak lainnya.

We present a transit-timing variation (TTV) and planetary atmosphere analysis of the Neptune-mass planet HAT-P-26 b. We present a new set of 13 transit light curves from optical ground-based observations and combine them with light curves from the Wide Field Camera 3 on the Hubble Space Telescope, the Transiting Exoplanet Survey Satellite, and previously published ground-based data. We refine the planetary parameters of HAT-P-26 b and undertake a TTV analysis using 33 transits obtained over seven years. The TTV analysis shows an amplitude signal of 1.98 ± 0.05 minutes, which could result from the presence of an additional ∼0.02 M

A Crater Chronology for the Jupiter’s Trojan Asteroids
Authors: Marchi S. , Nesvorný D. , Vokrouhlický D. , Bottke W. F. , Levison H.
Published: November 2023

We present a new crater chronology for Jupiter’s Trojan asteroids. This tool can be used to interpret the collisional history of the bodies observed by NASA’s Lucy mission. The Lucy mission will visit a total of six Trojan asteroids: Eurybates, Polymele, Orus, Leucus, and the near-equal-mass binary Patroclus–Menoetius. In addition, Eurybates and Polymele each have a small satellite. Here we present a prediction of Trojan cratering based on current models of how the solar system and the objects themselves evolved. We give particular emphasis to the time lapsed since their implantation into stable regions near Jupiter’s Lagrangian L4 and L5 points. We find that cratering on Trojans is generally dominated by mutual collisions, with the exception of a short period of time (∼10 Myr) after implantation, in which cometary impacts may have been significant. For adopted crater scaling laws, we find that the overall spatial density of craters on Trojans is significantly lower than that of Main Belt asteroids on surfaces with similar formation ages. We also discuss specific predictions for similar-sized Eurybates and Orus, and the binary system Patroclus–Menoetius.
Insights into Density and Location Diagnostics of Photoionized Outflows in X-Ray Binaries
Authors: Mitrani Sharon , Behar Ehud
Published: November 2023

The population of metastable levels is key to high-precision density diagnostics of astrophysical plasmas. In photoionized plasmas, density is used to infer the distance from the ionizing source, which is otherwise difficult to obtain. Perfecting models that compute these populations is thus crucial. The present paper presents a semianalytic hydrogenic approximation for assessing the relative importance of different processes in populating atomic levels. This approximation shows that in the presence of a radiation source, photoexcitations and collisional excitations are both important over a wide range of plasma temperatures and ionizing spectra, while radiative recombination is orders of magnitude weaker. The interesting case of Fe+21 with a collisional radiative model with photoexcitation demonstrates this effect. The population of the first excited metastable level in Fe+21 is sensitive to the electron number density in the critical range of n

e
= 1012–1015 cm−3; it was observed to be significantly populated in the X-ray spectrum of the 2005 outburst of the X-ray binary GRO J1655-40. The present model shows that photoexcitation is the predominant process indirectly populating the metastable level. For the photoionized plasma in the GRO J1655-40 outflow, the model indicates a measured value of n

e
= (2.6 ± 0.5) × 1013 cm−3, implying a distance from the source of r = (4.4 ± 0.4) × 1010 cm. Finally, we show how the computed critical density and distance of Fe+21 yield the correct ionization parameter of the ion, independent of ionization balance calculations.
TRAO Survey of Nearby Filamentary Molecular Clouds, the Universal Nursery of Stars (TRAO-FUNS). III. Filaments and Dense Cores in the NGC 2068 and NGC 2071 Regions of Orion B

Published: November 2023

We present the results of molecular line observations performed toward the NGC 2068 and NGC 2071 regions of the Orion B cloud as the TRAO-FUNS project to study the roles of the filamentary structure in the formation of dense cores and stars in the clouds. Gaussian decomposition for the C18O spectra with multiple velocity components and the application of a friends-of-friends algorithm for the decomposed components allowed us to identify a few tens of velocity-coherent filaments. We also identified 48 dense cores from the observations of N2H+ using a core finding tool, FellWalker. We performed a virial analysis for these filaments and dense cores, finding that the filaments with N2H+ dense core are thermally supercritical, and the filaments with a larger ratio between the line mass and the thermal critical line mass tend to have more dense cores. We investigated the contribution of the nonthermal motions in dense cores and filaments, showing the dense cores are mostly in transonic/subsonic motions while their natal filaments are mostly in supersonic motions. This may indicate that gas turbulent motions in the filaments have been dissipated at the core scale to form the dense cores there. The filaments with (dynamically evolved) dense cores in infalling motions or with NH2D bright (or chemically evolved) dense cores are all found to be gravitationally critical. Therefore, the criticality of the filament is thought to provide a key condition for its fragmentation, the formation of dense cores, and their kinematical and chemical evolution.

Essentially, AGNs are powered by the gravitational energy of matter falling into supermassive black holes. However, the conversion efficiency of gravitational to kinetic energy of CRs in AGNs, which is defined as the baryon loading factor η

p
, is not well known yet. After being accelerated, high-energy CRs could escape the host galaxy and enter the intracluster medium (ICM). These CRs can be confined within the galaxy cluster and produce γ-rays and neutrinos through proton–proton collisions with the ICM. In this paper, we study the diffusion of CRs in galaxy clusters and calculate the diffuse neutrino flux from the galaxy cluster population. Using the latest upper limits on the cumulative unresolved TeV–PeV neutrino flux from galaxy clusters posed by the IceCube Neutrino Observatory, we derive the upper limit of the average baryon loading factor as η

p,grav ≲ 2 × 10−3 − 0.1 for the population of galaxy clusters. This constraint is more stringent than the one obtained from γ-ray observation on the Coma cluster.

Low-frequency fluctuations in the interplanetary medium represent a turbulent environment where universal scaling behavior, generated by an energy cascade, has been investigated. On the contrary, in some regions, for example, the magnetosheath, universality of statistics of fluctuations is lost. However, at kinetic scales where energy must be dissipated, the energy conversion seems to be realized through a mechanism similar to the free solar wind. Here we propose a Langevin model for magnetic fluctuations at kinetic scales, showing that the resulting fluctuation–dissipation relation is capable of describing the gross features of the spectral observations at kinetic scales in the magnetosheath. The fluctuation–dissipation relation regulates the energy conversion by imposing a relationship between fluctuations and dissipation, which at high frequencies are active at the same time in the same range of scales and represent two ingredients of the same physical process.
Toward Interpreting the IBEX Ribbon with Mirror Diffusion in Interstellar Turbulent Magnetic Fields

We investigate the role of the magnetohydrodynamic (MHD) turbulence measured by Voyager in the very local interstellar medium (VLISM) in modeling the Interstellar Boundary Explorer ribbon. We demonstrate that the mirroring by compressible modes of MHD turbulence dominates over that by the mean magnetic field. Based on the new mirror diffusion mechanism identified by Lazarian & Xu for particles with large pitch angles in MHD turbulence, we find that the mirror diffusion can both confine pickup ions and preserve their initial pitch angles, and thus it accounts for the enhanced intensity of energetic neutral atoms that return to the heliosphere. The ribbon width is determined by both the range of pitch angles for effective turbulent mirroring and the field line wandering induced by Alfvénic modes. It in turn provides a constraint on the amplitude of magnetic fluctuations of fast modes. The field line wandering also affects the coherence of the ribbon structure across the sky. By extrapolating the magnetic energy spectrum measured by Voyager, we find that the injection scale of the turbulence in the VLISM must be less than ∼500 au for the ribbon structure to be coherent.

Perilimnastes is a genus currently treated in the polyphyletic Phyllagathis. Recent phylogenomic analyses have identified a morphologically cohesive lineage referred to as the Phyllagathis (raphides) clade, which should be excluded from Phyllagathis and treated as a distinct genus under the name Perilimnastes. Morphological and phylogenomic data have confirmed that four new species collected from Vietnam are part of the Phyllagathis (raphides) clade. They are described herein as Perilimnastes multisepala, P. setipetiola, P. uniflora, and P. banaensis. Perilimnastes multisepala is phylogenetically closest to Phyllagathis setotheca, and morphologically to P. fruticosa and P. stenophylla, but is distinct in the 4- to 8-lobed calyx, 28 × 9 mm, apically long acuminate petals, and 1–2 mm pedicel at fruiting stage. Perilimnastes setipetiola, P. uniflora, and P. banaensis are phylogenetically most closely related. Perilimnastes uniflora is characterized by its prostrate habit, small size, glabrous, obovate to obovate-lanceolate leaf blade, and solitary flower. Perilimnastes setipetiola and P. banaensis resemble each other in habit, leaf size and shape, and sessile or near sessile inflorescences but can be easily distinguished by the indumentum of the stems and leaves.

Post-translational modifications (PTMs) are protein modifications that occur after protein biosynthesis, playing a crucial role in regulating protein function. They are involved in the functional expression of G-protein-coupled receptors (GPCRs), as well as intracellular and secretory protein signaling. Here, we aimed to investigate the PTMs of the apelin receptor (APLNR), a GPCR and their potential influence on the receptor's function. In an in vitro experiment using HEK cells, we only observed glycosylation as a PTM of the APLNR and ineffective receptor signaling by the agonist, (Pyr1)-apelin-13. In contrast, when analyzing mouse spinal cord, we detected glycosylation and other PTMs, excluding isopeptidation. This suggests that additional PTMs are involved in the functional expression of the APLNR in vitro. In summary, these findings suggest that the APLNR in vivo requires multiple PTMs for functional expression. To comprehensively understand the pharmacological effects of the APLNR, it is essential to establish an in vitro system that adequately replicates the receptor's PTM profile. Nonetheless, it is crucial to overcome the challenge of heat-sensitive proteolysis in APLNR studies. By elucidating the regulation of PTMs, further research has the potential to advance the analysis and pharmacological studies of both the apelin/APLNR system and GPCR signal modulation.

Mobile augmented reality (MAR) has gained significant attention in the tourism sector as a way to enhance the visitor experience. The rapid advancements in mobile computing and sensor technologies have facilitated the widespread use of geospatial augmented reality (AR) applications by tourists when exploring popular destinations. To analyze the impact of AR technology on the tourism experience, we developed the FEZAR mobile application. This application serves as the focal point of our study, allowing us to evaluate user performance using a comparative experimental approach. To ensure the usability of the FEZAR application, professionals with expertise in mobile technologies, including AR, performed rigorous testing and evaluation of the application. Through their evaluations, significant usability issues were identified and resolved, resulting in the application being well-received by the experts. Subsequently, a comparative field study was conducted in Fez’s old medina, a crowded UNESCO heritage site, involving users (N = 40) who were randomly assigned to experimental and control groups in equal distribution. The results of the study revealed that the proposed AR model had a significant positive impact on user visits. Compared to other forms of media, AR offers more informative and enjoyable experiences. Additionally, it effectively helps locate monuments in crowded tourism settings. The findings of this research make a valuable contribution to the ongoing discussion regarding the impact of evaluating MAR user interfaces on increasing visitor engagement with tourist destinations.

This study examines the correlation between female body image and social media usage, focusing on the impact it has on overall well-being. The popularity of social networking sites (SNSs) has significantly impacted our digital culture, providing options for self-expression, engagement, and communication. However, SNSs also bring certain drawbacks, such as the potential for body dissatisfaction and negative psychological effects. Gap: While previous research has examined the relationship between social media use and body image, there is a need for a comprehensive analysis that specifically focuses on the effects on female well-being. This study aims to fill the gap by providing a comprehensive exploration of the effects of social media use on female body image and its influence on overall well-being. The objective of this study is to examine the correlation between social media usage and female body image, specifically focusing on the detrimental effects on well-being and mental health. By analyzing academic papers and research findings, this study aims to contribute to the understanding of the intricate relationship between social media, body image, and well-being. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) framework was used to compile relevant literature. Data from Scopus sources was analyzed using the RStudio 4.2.1-win program. Various factors, such as the publishing year, author details, keywords, and document categories, were considered to identify important patterns and insights. It is recommended that awareness and educational campaigns be developed to promote a healthy body image and address the potential negative consequences of social media use.

Published: November 2023

En proie aux déséquilibres territoriaux, à l’injustice sociale et à l’inégalité d’accès aux services urbains, les pouvoirs publics togolais ont entrepris, ces dernières années, de concrétiser le processus de décentralisation. Ils utilisent ainsi des stratégies de développement local mettant en jeu des processus participatifs impliquant les populations locales, la société civile, les secteurs privés et publics qui collaborent pour réduire la pauvreté. Cette recherche analyse les articulations entre l’État et les organisations communautaires dans la conduite des projets de développement à partir des données documentaires sur la coproduction des services urbains et d’une approche qualitative basée sur des entretiens dans certaines villes togolaises.
