Metric-based analysis of the historical drivers of surface hydrological connectivity
Authors: Antonelli Marta , Scherelis Victoria , Weber Christine
Published: February 2025

Abstract. Hydrological connectivity is essential for the maintenance of important hydrological and ecological processes of catchments. Over time, human activities have altered the natural patterns of hydrological connectivity, leading to habitat loss and deterioration. Historical information from cartographic maps can be used to enhance our understanding of large-scale hydrological processes such as connectivity, by offering snapshots of past, less human-impacted landscapes and hydrological systems. The focus of this study is on historical surface hydrological connectivity and its landscape drivers (e.g., lithology, topography, land use/ land cover) in ten Swiss catchments from different biogeographic regions (i.e., Pre-alpine, Alpine, Karstic, Plateau), and with varying physiographic characteristics. We employed hydromorphological metrics derived from historical maps (~ late 19th century) as proxies of surface hydrological connectivity, with the main goal of identifying the primary landscape drivers of connectivity. As expected from theory, the historical patterns of hydrological connectivity in the studied catchments were mostly driven by landscape topography, and in particular by the slope and the morphology of the valley bottom. Unexpected relationships between connectivity and its drivers could be traced back to human practices, such as specific irrigation techniques and peat digging. Overall, our study shows how historical information can be employed to gain a deeper understanding on important large-scale hydrological processes, their primary drivers and on the history of human exploitation of the territory. Finally, this kind of approach paves the way for the characterization of how connectivity has changed through time.

Published: February 2025

Abstract. Landslide thickness is a key variable in various types of landslide susceptibility models. In this study, we developed a model providing improved predictions of potential shallow-landslide thickness for Switzerland. We tested three machine learning (ML) models based on random forest (RF) models, generalised additive models (GAMs), and linear regression models (LMs). Next, we compared the results to three simple models that link soil thickness to slope gradient (Simple-S/linear interpolation and SFM/log-normal distribution) and elevation (Simple-Z/linear interpolation). The models were calibrated using data from two field inventories in Switzerland (HMDB with 709 records and KtBE with 515 records). We explored 39 different covariates, including metrics on terrain, geomorphology, vegetation, and lithology, at three different cell sizes. To train the ML models, 21 variables were chosen based on the variable importance derived from RF models and expert judgement. Our results show that the ML models consistently outperformed the simple models by reducing the mean absolute error by at least 20 %. The RF models produced a mean absolute error of 0.25 m for the HMDB and 0.20 m for the KtBE data. Models based on ML substantially improve the prediction of landslide thickness, offering refined input for enhancing the performance of slope stability simulations.
Can the Mann model describe the typhoon turbulence?
Authors: Müller Sara , Guo Larsén Xiaoli , Hu Fei
Published: February 2025

Abstract. More and more wind farms are planned and built in regions prone to tropical cyclones. However, the current International Electrotechnical Commission (IEC) standard provides no clear guidelines on how to account for turbulence occurring during tropical cyclones. This study investigates how well the Mann turbulence model, a model referenced by the IEC, can model turbulence during tropical cyclone conditions. We analyzed sonic anemometer measurements at 60 m from four typhoon cases in the South China Sea. The Mann model was fit to the one-point spectra in different locations in the typhoon structure. We found that the Mann model can fit the observed spectra reasonably outside the typhoon eye and the rainbands. However, deficiencies are found regarding the following aspects: 1.) In the outer cyclone region, excessive energy is found at low wavenumbers smaller than 10−2.5 m−1 associated with quasi-two-dimensional turbulence, 2.) In the inner cyclone and eyewall regions of one of the typhoons, we observe excessive energy at wavenumbers larger than 10−1m−1, 3.) Enhanced 10 energy is found in the energy-containing subrange of the crosswind component in the inner cyclone region, and 4.) The energy level of the uw-cospectra is overestimated in the fitted Mann model. This study can serve as a baseline for further research addressing turbulence in tropical cyclones in the context of structural engineering.

Authors: Casadiego-Alzate Rodolfo , Balzan Alexander , Castañeda-Quirama Tatiana , Velásquez-Calle Paula Andrea
Published: February 2025

This study examines market segmentation within the gastronomic industry in Medellín, Colombia, focusing on perceived value, consumer types, and brand positioning among young adults. Using a mixed-method approach with a sequential exploratory design, focus groups were conducted to identify key attributes valued by consumers. This data was the base for a subsequent quantitative survey, which delineated three distinct market segments characterized by their preferences for connectivity, cleanliness, reasonable prices, ambiance, quality of service, variety in dishes, portion size, and service time. The results suggest that young adults in Medellín prioritize a combination of quality and experience factors in their gastronomic choices. The conclusions highlight sociodemographic differences, such as the tendency of women to seek information about establishments before visiting the establishments or the preference of middle-class youth for casual dining restaurants, results that contribute to marketing management and tourism decision-making.

Authors: Luna Morán Ismael , Manjarrés Tete Arleth , De La Hoz Suárez Aminta , De La Hoz Suárez Betty
Published: February 2025

La transformación global se debe al fomento del bienestar social universal, por eso, la Agenda 2030 delinea Objetivos de Desarrollo Sostenible, los cuales deben ser asumidos por los Estados miembros de la Organización de las Naciones Unidas. Ante ello, Colombia, como parte de este compromiso internacional, enfrenta los desafíos delineados en esta agenda para el desarrollo. Este estudio se enfoca en analizar los aspectos presupuestarios territoriales relacionados con los Objetivos de Desarrollo Sostenible en el Departamento del Magdalena en miras de su implementación. El enfoque metodológico es cuantitativo, de tipo básico y nivel descriptivo, utilizando un diseño no experimental y longitudinal de la información aportada por el Consolidador de Hacienda Pública, Estados Financieros del Departamento del Magdalena y el Plan de Desarrollo Departamental para los años 2018-2021. Se encontró que las asignaciones presupuestarias, basadas en criterios de asociación, respaldan los gastos de inversión social; sin embargo, la proporción presupuestaria destinada a necesidades críticas de la población del Departamento del Magdalena, como agua potable, saneamiento básico y reducción de la pobreza, es desigual. Por lo cual se concluye que es crucial asignar recursos significativos de manera prioritaria para la implementación de los Objetivos de Desarrollo Sostenible, asegurando una distribución más equitativa del presupuesto en las necesidades prioritarias de la población; de lo contrario, la esencia de lo delineado en la Agenda 2030 sería infructuosa en el caso colombiano, particularmente en Departamentos deprimidos por falta de asistencia social integral que genera la no atención al menos de necesidades básicas insatisfechas impidiendo el desarrollo local.

Published: February 2025

This article aims to provide a comparative analysis of the capital structure of large companies in the manufacturing sector of Colombia and Ecuador regarding company size, guarantees or tangibility, cost of debt, growth opportunities, reputation, and liquidity as determinant variables. Based on a sample of 509 manufacturing companies in Colombia and Ecuador, a panel data model was applied to estimate the determinants of the indebtedness of companies in this sector. The findings expose that in Colombia, the variables that influence the total indebtedness of companies are ROA, tangibility, and liquidity. In Ecuador, variables that influence the analysis of the total indebtedness of companies are ROA, size, tangibility, and liquidity. The Pecking Order Theory explains these results. This study contributes to understanding the determinants of companies’ financing types in Colombia and Ecuador, acknowledging that there are substantial differences between the economies of the two countries explained above, all by dollarization and the family structure of most companies in Ecuador and by more significant development in the Colombian stock market.
From Eco-Thriller to Eco-Horror: Eleanor Catton’s Birnam Wood as an Antipodean inversion of Bram Stoker’s Dracula
Authors: Novitz Julian
Published: February 2025

With its emphasis on the transgression of “natural” boundaries, the Gothic has always been a powerful medium for ecological themes. Bram Stoker’s Dracula (1897) focuses on a clash between civilised Europe and the wilderness on its fringes. Published at the height of Victorian techno-optimism, it shifts genres from Gothic horror to thriller as its protagonists apply modern science to determine the limits of the titular Count’s supernatural powers. The novel ends with the victory of their scientific-rationalist mindset and the taming of the dangerous natural world represented through Dracula’s uncanny hybridity. Stoker’s Dracula has had an enormous impact on horror and thriller genres, but Eleanor Catton’s Birnam Wood (2023) presents a notable inversion of both its central conflict and its structure. In Birnam Wood, the wild fringes of rural New Zealand are threatened by the civilised centre, represented by American tech-mogul Robert Lemoine. The novel gradually shifts from thriller to the horror genre, as Lemoine’s rationalistic mindset leads him into atrocity. His predations are enabled by his technological hybridity, through which he excerpts an almost supernatural influence over his environment. Birnam Wood provides an intriguing model for contemporary EcoGothic narratives, using the subversion of thriller and horror structures to foreground contemporary ecological anxieties.
Towards post-human storytelling: Pushing boundaries in decentring the human
Authors: Rozitis Stef , DeBono Dante , Brady-Clark Anne , Jarrett Evan , Walker Amelia
Published: February 2025

Can storytelling be(come) post-human? If so, how? This article shares creative insights from a collaborative inquiry at the intersection of queer, neurodivergent, and ecological writing. Writing from the fringes of our various disciplines and levels of precarity within the academy, we came together as a collective of researchers who share an interest in creative methods and an orientation towards storytelling as “a political and heuristic tool” involving “human and nonhuman” processes (Wiame, 2018). We made use of new materialist and posthuman perspectives as we grappled with an empathy that neither anthropomorphises nor objectifies the nonhuman Other, and seeks to portray the agency of a world that does not centre on the human, or not only the human. We sought to rewrite the human as marginal. This work, informed by theories of writing and artmaking as ways of knowing, engaged in poetic inquiry and co/autoethnography. Responding individually to shared creative prompts, we explored possibilities of writing as nonhuman entities. We then compared our writings, observing rhizomatic connections and branchings-out to explore the challenges and possibilities of post-human storytelling. Our article describes these insights and signals unfolding directions for ongoing inquiry and the challenges of storying from the margins of the human.
Hipotiposis de las virtudes del valido: heráldica y comunicación de una anomalía política en la primera modernidad: el duque Lerma.
Authors: Guillén Berrendero José Antonio
Published: February 2025

El texto quiere ofrecer una interpretación de la heráldica del duque de Lerma. Valido de Felipe III y verdadero muñidor de una intensa campaña de autopromoción y génesis de su propia imagen. Una forma de self fashioning avant la lettre. Para ello nos fijamos en el despliegue heráldico que el valido realizó desde sus años como duque de Gandía a hasta su ascenso al valimiento. Debemos entender que el valimiento era una condición anómala de la política en la Edad Moderna y que Lerma lo situó dentro de las coordenadas de la cultura visual de las noblezas europeas de la primera modernidad, haciendo de su heráldica, una hipotiposis de sus virtudes heroicas y linajísticas.
Humanities scholars’ needs for open social scholarship platforms as online scholarly information sharing infrastructure
Authors: Tracy Daniel , Jensen Graham
Published: February 2025

The contemporary scholarly communication environment is characterized by the growth in mandates and infrastructure for open access publication and open approaches to the research lifecycle, with a consequent explosion in the number of online platforms seeking to provide infrastructure for open scholarship. These include corporate academic social networks and scholar-governed infrastructure created as a reaction against those networks, as well as the recent major transformation of the social media landscape in the wake of changes at Twitter (now X), previously a major outlet for scholarly engagement with the public. Analysts of this environment have pointed out that most platform initiatives focus on narrow use cases rather than building up solutions through a holistic understanding of scholar workflows. This exploratory study uses focus group interviews to draw out responses to one academically governed platform, the Humanities and Social Sciences (HSS) Commons, in the context of humanities scholars’ existing work. It explores humanities scholars’ needs and behaviors related to sharing scholarly information with each other and broader audiences, particularly on the Internet. Feedback from participants sheds light on opportunities and challenges for academy-governed infrastructure for “open social scholarship.” Themes identified include technical fatigue and burnout in the current multi-platform environment, sustainability, and desires to reach and engage the right academic and non-academic audiences when appropriate.
Creating a simple mobile application to promote immigrant employment
Authors: Haavisto Piia , Uusitalo Tero
Published: February 2025

The purpose of this paper is to describe the development process of a mobile application that tries to solve the challenges that highly educated immigrants face when entering the Finnish labor market. Finland, as well as other Western societies, suffers from lack of labor force and immigration is considered one of the solutions to the problem. The idea of the application is to answer to questions or direct the immigrants to further information sources related to either finding a job or a place to study. This, in its turn, would shorten the period of non-employment by either directly helping highly educated immigrants to find a job or helping them to identify the gap in their knowledge that needs to be filled first.

Sexual violence, including sexual intercourse, can occur in women experiencing vaginal discharge, particularly in cases of vaginal candidiasis. In candidiasis, the vaginal microbiome undergoes changes that could serve as a diagnostic indicator or as evidence of sexual activity.  The aim of this study was to assess the effects of semen insemination on the vaginal microbiome profile of candidiasis rats and to determine its forensic investigations in cases of sexual violence.  An experimental study was carried out using Wistar strain rats (Rattus norvegicus), consisting of four male rats (for spermatozoa donors) and twenty-four female rats. The female rats were divided into four groups: normal condition (control), normal condition post-semen insemination, candidiasis rats, and candidiasis rat post-semen insemination. Vaginal microbiome profiles were examined for each group, using alpha diversity (Chao 1, Shannon, Simpson, and Faith PD indices) and beta diversity (Bray Curtis, Jaccard, Unweighted Unifrac and Weighted Unifrac indices). Data were analyzed using the Kruskal-Wallis test for alpha diversity and the PERMANOVA test for beta diversity. The vaginal microbiome profiles of normal and candidiasis rats showed no significant differences (p>0.05). In candidiasis rats, the microbiome predominantly consisted of the Eukaryota kingdom, particularly Candida albicans. Semen insemination did not significantly affect the vaginal microbiome profile of candidiasis rats in the short term (p>0.05). However, the study highlights that the presence of Eschericia-Shigella, Roseomonas, and Archaea in the vaginal microbiome post-semen insemination potentially serves as an indicator of infection or sexual activity in forensic contexts.

Published: February 2025

Pornografi hingga saat ini masih menjadi permasalahan di Indonesia. Ditambah dengan Perkembangan teknologi saat ini, komik digital menjadi salah satu media yang populer di kalangan masyarakat, termasuk di Indonesia. Namun, kemudahan akses dan distribusi komik digital juga membawa tantangan baru terkait penyebaran konten pornografi. Tentunya hal tersebut mempunyai dampak negatif bagi yang mengkonsumsinya. meskipun terdapat peraturan yang mengatur tentang pornografi, implementasi dan pengawasan terhadap konten pornografi dalam komik digital masih kurang efektif. Beberapa faktor yang mempengaruhi hal ini antara lain adalah kurangnya kesadaran hukum di kalangan masyarakat, serta keterbatasan teknologi dalam mendeteksi dan memblokir konten pornografi. Penegakan hukum terkait pornografi masih dianggap lemah karena dari banyaknya kasus pornografi yang diblokir oleh pemerintah, namun masih saja banyak beredar konten-konten pornografi secara bebas tanpa adanya filterisasi konten. Komik digital yang semula dianggap sebagai media penyaluran ide kreatif, kini menjadi salah satu media penyebaran pornografi. Pengaturan terkait pornografi juga belum maksimal karena faktor media sosial yang bersifat universal dan faktor penyebaran yang cepat. Evaluasi terhadap peraturan terkait perlu dilaksanakan, begitu juga dengan aparat penegak hukum dalam membatasi bahkan menutup akses pornografi.

This study discusses the challenges associated with estimating the population coefficient of variation using sampling survey techniques. Yunusa et al. (2021) motivate this study. We further improve these estimators to estimate this study's unknown population coefficient of variation. Using two populations as examples, empirical results indicate that the proposed estimator provides more accurate estimates of population variability since it is more efficient. Further research and validation are recommended to establish the robustness and generalizability of the proposed estimator.

For the women of reproductive age, which carried organ-preserving, surgical interferences on the organs of small pelvis concerning the of high quality diseases of ovaries, uterus and isolated pipe peritoneal factor of infertility during 6 months after an operation there is violation of functional activity of ovaries exhaustion of ovarian reserve. The most expressed changes are observed at initial pathology of ovaries.During 6 months after organ-preserving operative interferences on the organs of small pelvis for the patients of reproductive age, regardless of nosology, hypergonadotropic hypogonadism is formed from hypoestrogenism and hypoandrogenism, and also decline of ovarian reserve (in 4 times), not conditioned by autoimmune aggression. The found out the changes of parameters of hormonal status answer the clinical picture of premature exhaustion of function of ovaries. For the maintaining of the functional state of ovaries and ovarian reserve of the use of laparotomy as operative access more spares, that it follows to take into account at operative interferences on the organs of small pelvis for the women of reproductive age, interested in realization of reproductive function. At the choice of laparoscopy as access at organ-preserving operations on the organs of small pelvis of the use of monoarctic electrosurgery more spares from positions of maintaining of ovarian reserve, that it follows to take into account for the women of reproductive age interested in realization of reproductive function.Conclusions. The got results it follows to draw on at development of algorithm of diagnostic, treatment-and-prophylactic and recovery measures.Keywords: ovarian reserve, ovarian surgery.

Published: February 2025

The objective: to learn the role of cytokines in efficiency of gonadotropic stimulation of ovaries in the loop of assisted reproductive technologies and his results at the matrimonial pair of reproductive age with the combined forms of infertility.Materials and methods. 70 matrimonial pair of reproductive age, which made the followings groups, were inspected: basic (n=30), comparison (n=30) and control (n=10). Plugging criteria in a basic group were: age 25–38 years; infertility (endocrine, pipe peritoneal, combined); program of assisted reproductive technologies; stimulation of ovaries by preparations of gonadotropins; an offensive of pregnancy is after the real program of assisted reproductive technologies (visualization of ovum at ultrasonic research in 3 weeks after transference of embryos). In the complex of the conducted researches were included clinical, echographic, endocrinology, morphological, statistical and immunological methods.Results. Findings testify that strengthening of secretion in the ovary of pro-inflammatory cytokines can be one of mechanisms of unfavorable influence of stimulation of ovaries of gonadotropins on an oocyte. It is presently foreseen that stimulation of ovaries, its modes influence on «quality» of oocyte, potency of him to the impregnation and rates of early development of embryo. A negative role high concentrations can play in blood of estradiol, and also pharmacological preparations which are used during stimulation of ovaries (gonadotropins, agonists and antagonists of gonadotropin-releasing hormone). The got results were confirmed by present fundamental pictures that co-operation between an oocyte and somatic cages of ovary is critical for normal motion of oogenesis, impregnation and early development of embryo.Conclusions. The results of the conducted researches testify that to informing clinical-and-anamnestic and hormonal factors which determine the result of cycle of assisted reproductive technologies for the patients of reproductive age with the combined forms of infertility, take: age of the patient; body mass index; presence pipe peritoneal factor of infertility; a level of free testosterone is in blood; a table of contents of progesterone is in blood on 20–22 days of menstrual cycle, and also determination in the follicle liquid of ovaries of cytokines.Keywords: the combined forms of infertility, assisted reproductive technologies, efficiency, are immunological factors.

Feature-Augmented Convolutional Neural Network Optimisation for Wheat Yellow Rust Identification
Authors: Komal Mishra
Published: February 2025

Nowadays, yellow rust is a type of condition having a huge domain triggering excessive adverse effects on wheat. Manually addressing wheat yellow rust using the standard approach is not highly effective. In order to enhance this condition, a Deep Learning (DL)-based method was applied in this analysis to identify wheat yellow rust from the Yellow Rust-19 dataset leaf images. The solution offered was constructed using the Optimized Feature-Augmented Convolutional Neural Network (OFAC-Net) model to classify R (Minor infection), MR (Small and Medium Infection), MR-MS (Moderate Resistance and Susceptible), MS (Medium Infection), and S (Major signs of infection), aiming to improve the efficiency of detecting and classifying yellow rust in wheat leaf images. The implemented OFAC-Net models integrate Principal Component Analysis (PCA) used for feature extraction and reduce the dimensionality, alongside hybrid feature selection techniques utilizing the Whale Optimization Algorithm (WOA) and Firefly Algorithm (FFA) to refine the extracted features and boost accuracy. This combination addresses existing challenges and improves classification performance, with the results being classified through a Convolutional Neural Network (CNN). The implemented model attained a classification Accuracy of 98%, Precision of 98.76%, Recall of 99%, and Mean Square Error (MSE) of 1.98%. The dataset, curated from the several severity levels of yellow rust disease, in wheat, consists of a total of 15,000 wheat leaf images. It was designed to support the classification tasks, with leaf images evenly divided across severity levels of yellow rust disease in wheat. These results highlight the techniques` superiority over traditional machine learning (ML) techniques and other advanced models. The proposed OFAC-Net model is a promising solution for real-time agricultural applications, offering both high performance and computational efficiency suitable for mobile and edge devices.
