Exploring the effects of topography and land-ice coverage on Paleoproterozoic deglaciation

description: The Paleoproterozoic glaciation (~2500-1600 Ma) was a time period in Earth’s history when its surface was completely covered in ice, creating a climate state known as a Snowball Earth. The Neoproterozoic glaciation (~1000-539 Ma), on the other hand, was a “Slushball" Earth climate state with partially ice-covered continents and open equatorial waters. This partial ice coverage and the presence of open equatorial waters during the Slushball period facilitated an active hydrological cycle, playing a key role in deglaciating the Earth during the Neoproterozoic. However, the process of transitioning from the Paleoproterozoic Snowball Earth to a Slushball Earth state (similar to the conditions seen during the Neoproterozoic) remains poorly understood. The complete ice coverage of the Snowball Earth shuts down the hydrological cycle, effectively isolating the oceans from the atmosphere and hindering deglaciation. This stark difference in the behavior of the hydrological cycle presents a challenge in explaining how the Paleoproterozoic Snowball Earth underwent a deglaciation process similar to the Neoproterozoic Slushball Earth. The buildup of CO2 through volcanic emissions is a possible deglaciation mechanism for a Snowball Earth since oceanic ice coverage inhibits the removal of atmospheric CO2 through weathering and the oceans. Experiments with varying CO2 concentrations are currently being performed to test how high CO2 needs to be to deglaciate a Snowball Earth but these simulations assume no permanent ice sheets or topography on land. To test the implications of varying topography and the extent of the ice sheets on how high CO2 needs to be to deglaciate the Paleoproterozoic Snowball Earth we are designing new boundary condition files for a global climate model with a coupled dynamic ocean model (ROCKE-3D). The topography for these boundary condition files was edited by placing the elevation data from the Tibetan Plateau, Andes Mountains, and Rocky Mountains in various locations on the landmass. The land ice cover was edited by changing the maximum latitude at which ground ice was present.

description: Die vorliegende Arbeit geht der Frage nach, ob ein dreitägiges handlungsorientiertes Natur- und Selbsterfahrungsseminars nach dem Konzept der IOA® Auswirkungen auf Komponenten der psychischen Gesundheit (Resilienz, Achtsamkeit, emotionale Unterstützung und Befindlichkeit) bei Personal der Psychosozialen Notfallversorgung des Österreichischen Roten Kreuzes, Landesverband Salzburg hat. Um dies herauszufinden wurde ein quasi-experimentelles prä-post Studiendesign mit einer Versuchsgruppe (n = 9), einer Kontrollgruppe mit alternativer Intervention (n = 14) und einer Kontrollgruppe ohne Intervention (n = 12) zu drei Testzeitpunkten (T1: vor dem Seminar, T2: nach dem Seminar und T3: 6 Wochen später) mit quantitativer Forschungsausrichtung und dem nparLD-Modell zur statistischen Auswertung angelegt. Die Stichprobengröße wurde aufgrund der Covid-19 Pandemie erheblich reduziert, weshalb jegliche Ergebnisse maximal als Tendenz angesehen werden sollten. Im Konstrukt der Resilienz, gemessen mit dem CD-RISC-10, ergab sich langfristig ein hoch signifikanter Zeiteffekt (p = .001) über alle Gruppen, wobei sich die Versuchsgruppe nicht signifikant von den Kontrollgruppen abhebt. Im Konstrukt der Achtsamkeit, gemessen mit dem CHIME, gab es langfristig Tendenzen eines Gruppen-Zeit-Interaktionseffekts (p = .080), welche sich in nicht-korrigierten Einzelvergleichen teilweise als signifikant herausstellten und sich in einer Sample Size Simulation bei N = 50 stabilisieren ließen. Im Konstrukt der emotionalen Unterstützung, gemessen durch den F-SozU gab es einen deutlichen Deckeneffekt und dementsprechend keine Veränderungen. Im Konstrukt der Befindlichkeit, gemessen mit dem MBDF, zeigten sich in nicht-korrigierten Einzelvergleichen Tendenzen in Richtung kurzfristiger, positiver Stimmungsveränderung der Versuchsgruppe gegenüber den Kontrollgruppen. Kombiniert mit den Ergebnissen von Jank (2021), welche an der gleichen Stichprobe mit qualitativen Methoden forschte, zeigt sich ein vorsichtig optimistisches Bild hinsichtlich der Wirksamkeit von handlungsorientierten Seminaren nach IOA® in Bezug auf die psychische Gesundheit. Dieses Ergebnis bietet zum einerseits eine motivierende Grundlage für weitere Forschung in diese Richtung und ermutigt andererseits dazu, bestehende Aus- und Fortbildungsangebote im Sinne der betrieblichen Gesundheitsförderung, um handlungsorientierte Interventionen nach dem IOA®-Konzept zu erweitern.

description: We consider flows over time within the deterministic queueing model and study the solution concept of instantaneous dynamic equilibrium (IDE) in which flow particles select at every decision point a currently shortest path. The length of such a path is measured by the physical travel time plus the time spent in queues. Although IDE have been studied since the eighties, the efficiency of the solution concept is not well understood. We study the price of anarchy for this model and show an upper bound of order $\mathcal{O}(U\cdot τ)$ for single-sink instances, where $U$ denotes the total inflow volume and $τ$ the sum of edge travel times. We complement this upper bound with a family of quite complex instances proving a lower bound of order $Ω(U\cdot\logτ)$.

description: This project investigates antimicrobial peptides (AMPs), cytokines, and chemokines present in Xenopus laevis (African clawed frog) skin tissue, using Trizol for protein extraction and Tandem Mass Spectrometry (MS/MS) results to identify AMPs. Antimicrobial peptides are small proteins consisting of short chains of amino acids that can have antibacterial, antiviral, antifungal, anticancer, and other biological activities. Studying immunity in frogs is important because immunity in amphibians is poorly understood and has not been investigated as thoroughly as in other animals. Most of the research conducted on frogs to date has focused on their skin secretions rather than frog tissue. This research will contribute to our fundamental understanding of immunity in frogs and may be applicable to humans’ own host defense systems, as well. In this study, Trizol and bead beating are compared to see which method of protein extraction works best for frog tissue. Once the method of protein extraction from tissue has been established, C8 and C18 columns will be compared during the solid phase extraction portion of the protocol. After analyzing the resulting samples using tandem mass spectrometry, the data will be processed to determine the proteins and peptides that are present in the tissue samples.

description: We give a sufficient condition for the Fourier dimension of a countable union of sets to equal the supremum of the Fourier dimensions of the sets in the union, and show by example that the Fourier dimension is not countably stable in general. A natural approach to finite stability of the Fourier dimension for sets would be to try to prove that the Fourier dimension for measures is finitely stable, but we give an example showing that it is not in general. We also describe some situations where the Fourier dimension for measures is stable or is stable for all but one value of some parameter. Finally we propose a way of modifying the definition of the Fourier dimension so that it becomes countably stable, and show that a measure has modified Fourier dimension greater than or equal to $s$ if and only if it annihilates all sets with modified Fourier dimension less than $s$.

description: Since its inception as an academic concept in the 1980s, intersectionality as a framework has traveled across various academic and social disciplines. Like many ideas, it has undergone adaptations in response to different environments, leading to deviations from its original intended meaning with each transfer. Computer sciences, particularly machine learning, have been heavily influenced by the introduction of intersectionality as both a theory and methodology. This influence is likely attributed to the increased exposure of intersectional bias instances. Our research seeks to examine the interpretation and application of intersectionality within the domain of machine learning. By analyzing three case studies through the lens of the theory’s initial proponents, we aim to provide comprehensive guidelines that address the challenge of evaluating the appropriate integration of intersectionality into machine learning practice.

The conceptualization groundwork for indicators of Interdisciplinarity – A closer look at section references
Creators: name: Meier, Max
Publisher: name: Zenodo

description: Collaborations and interactions across boundaries has increasingly been recognized as important means to tackle the complexity of today’s societal challenges. Within the sciences, such boundary-crossing is manifested by different modes of interdisciplinary research (IDR), involving multi-, inter-, intra-, cross-, or transdisciplinary engagement of and with knowledge. Recognizing both the perceived scientific and societal promises of IDR, as well as the systemic barriers against and individual and collaborative challenges with engaging in IDR, several scientific funding organizations have made IDR a key funding priority. Much academic research has been devoted to better conceptualize, delineate and measure the phenomenon. In particular, bibliometric indicators have proliferated that define IDR in terms of knowledge integration at different levels of granularity. Usually, the focal dimension of knowledge integration is represented by diversity, which itself consists of three components: variety as the number of disciplinary categories, balance as the evenness of the distribution and disparity as the degree of difference between the categories. Diversity measures either combine or separate those three components in capturing the degree of IDR as knowledge integration; following the cognitive approach, these are usually applied to the publication’s reference list, where the references are usually assigned to disciplinary categories via their journals.

description: Neutrophils, a type of white blood cell, play a crucial role in immune function and wound repair. In humans, there is evidence that neutrophils aid blood coagulation through interactions with the injured endothelium and fibrin. Myeloperoxidase (MPO) can be used as a marker for neutrophil infiltration into tissues because it is one of the most abundant proteins in neutrophil cells. In the present study, three cultured human blood clot samples were immunostained for MPO expression using goat anti-MPO primary antibody and donkey anti-goat green fluorescent secondary antibody. Nuclei were stained with a blue fluorescent DNA-binding dye called Hoescht 33342. MPO staining patterns were compared across samples, with a focus at the top of the blood clot. Analysis using fluorescence microscopy revealed co-localization of cell nuclei and MPO proteins in all three samples as well as proximity of multiple stained MPO proteins to cell nuclei. Based on the results of this study, it can be concluded that neutrophils, as indicated by MPO staining, are present and actively involved in the clotting process in human blood clots. These findings support the existing evidence that neutrophils survive and have a functional role in blood coagulation and provide specific insights into their localization within the clot structure. In the future, double immunostaining could be conducted with multiple neutrophil markers to differentiate between types of neutrophils to better understand the role of neutrophils encapsulated in a thrombus.

description: In recent years, groundwater contamination by fracking fluid has become a prevalent issue in rural communities. Ethylene glycol (EG) is one of the many hazardous chemicals that make up fracking fluid and with its neurotoxic properties, fracking is not only an environmental risk but also a public health concern. EG is a known central nervous system depressant like ethanol, but its exact mechanism in impairing neurological function in EG poisoning is unknown. Ethanol has been shown to positively modulate inhibitory glycine receptors, therefore EG toxicity is suspected to have a similar mechanism. To test this, glycine receptor alpha 1 (GlyRα1) will be expressed in Xenopus laevis oocytes and a two-electrode voltage clamp will be used to record the induced currents by clamping the voltage at -60 mV. Currents at varying glycine concentrations will be measured without and with EG as the control and experimental treatment, respectively. When the EG concentration is held constant, increasing the glycine concentration is theorized to increase GlyRα1 efficacy and result in a higher maximal current compared to the control. These findings would suggest that EG is a positive allosteric modulator of GlyRα1. In the future, treatments for EG poisoning could focus on glycine receptor function.

description: Climate change has a profound impact on the natural resources in the Sahel region. To understand vegetation dynamics and precipitation changes, this study examines the spatial-temporal trends in the Sahel over the years 2000-2020. The MODIS Normalized Difference Vegetation Index (NDVI) and Merged Satellite-Gauge Precipitation Estimate (IMERG) datasets are utilized, employing linear regression and Pearson correlation analysis to assess the relationship between vegetation index and rainfall, and explore seasonal correlations to understand variations during the growing season (July-October). The results show an increase in average annual NDVI (0.0005 yr-1, p < 0.05) and precipitation (0.0003 mm/hr/yr, p < 0.05). NDVI (0.0009 yr-1, p < 0.05) and precipitation (0.0009 mm/hr/yr, p < 0.05) in the growing season also show a rise. The south-central Sahel experiences the largest NDVI increase (11.66%), while the northeast sees the highest precipitation rise (125.15%) from 2000 to 2020. Additionally, a correlation map between rainfall and NDVI highlights that during the growing season, 18.505% of pixels exhibit a positive correlation above 0.7 with the southwestern part showing the highest correlation. These seasonal correlations shed light on the intricate interactions between NDVI and rainfall in different periods, offering valuable insights for ecosystem management in the Sahel. This study provides valuable support for conservation efforts, highlighting the importance of understanding these trends urgently to safeguard the region’s natural resources and bolster the Africa-Water-Energy-Food-Health (AWEFH) Nexus.

description: We generalize the embedding of induced-gravity inflation beyond the no-scale Supergravity presented in arXiv:1403.5486 employing two gauge singlet chiral superfields, a superpotential uniquely determined by applying a continuous R and a discrete Zn symmetries, and a logarithmic Kahler potential including all the allowed terms up to fourth order in powers of the various fields. We show that, increasing slightly the prefactor (-3) encountered in the adopted Kahler potential, an efficient enhancement of the resulting tensor-to-scalar ratio can be achieved rendering the predictions of the model consistent with the recent BICEP2 results, even with subplanckian excursions of the original inflaton field. The remaining inflationary observables can become compatible with the data by mildly tuning the coefficient involved in the fourth order term of the Kahler potential which mixes the inflaton with the accompanying non-inflaton field. The inflaton mass is predicted to be close to 10^14 GeV.

description: Die Masterarbeit erforscht die Frage des Erlebens von Kooperation von Jugendlichen mit Behinderung mit den Eltern und den professionellen AkteurInnen am Übergang von der Schule in den Beruf. Das analysierte Datenmaterial in diesem Forschungsprozess bilden zwei längsschnittlich geführte narrative Interviews, welche im Rahmen des FWF – Forschungsprojektes ‚Kooperation für Inklusion in Bildungsübergängen‘ geführt worden sind. Die Forschungsmethode in diesem Forschungsprozess ist die zusammenfassende qualitative Inhaltsanalyse. Das Ziel in diesem Forschungsprozess war der Erkenntnisgewinn über das Erleben der Kooperation einer jugendlichen Person mit Behinderung mit den Eltern und den professionellen AkteurInnen am Übergang von Schule in Beruf. Die gewonnenen Erkenntnisse wurden genutzt, um Rückschlüsse über die Unterstützungsleistungen am Übergang von der Schule in den Beruf zu ziehen. In einem weiteren Schritt wurden die Ergebnisse unter meritokratischen Gesichtspunkten diskutiert. Der Forschungsprozess hat zur Bildung von sieben Kategorien geführt, welche beim Erleben der Kooperation als relevant zu erachten sind. Diese sind die Eltern, die professionellen AkteurInnen, Kommunikation, Miteinander, Peergruppe, Zeit und Wünsche. Es konnte gezeigt werden, dass diese Kategorien in direkter oder indirekter Verbindung zu setzten sind und maßgeblich für die erfolgreiche Bewältigung des Übergangs von Jugendlichen mit Behinderung von der Schule in den Beruf zu erachten sind. Die Ergebnisse wurden durch die Habitustheorie, welches durch das Konzept der symbolischen Gewalt erweitert wurde, theoretisch gerahmt. Es konnte gezeigt werden, dass gesellschaftliche Prozesse der sozialen Reproduktion am Übergang von der Schule in den Beruf wirksam werden.

description: Droughts pose significant challenges to Eastern Sub-Saharan Africa (including Kenya, Tanzania, and Uganda), affecting agriculture, water resources, and socio-economic development. A recent study by the United Nations Office for the Coordination of Humanitarian Affairs found that from July to September 2022, about 3.5 million people in Kenya alone are facing high levels of acute food insecurity, a 10% increase from the same period in 2021. Monitoring and early warning of droughts is crucial to implementing effective mitigation and adaptation strategies that are currently severely lacking in Eastern Sub Saharan Africa. This study aims to utilize satellite remote sensing data to analyze drought events in Kenya. The key datasets used in this study are the Normalized Difference Vegetation Index (NDVI) data product from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) measurements, as well as the Vegetation Health Index (VHI), and Vegetation Condition Index (VCI) derived from NDVI. Together with rainfall data from the final run estimates of the Integrated Multi-satellite Retrievals for GPM (IMERG) (developed by fusing together the precipitation estimates collected in 2000-2014 during the operation of the Tropical Rainfall Measuring Mission (TRMM) satellite with more recent precipitation estimates collected during operation of the GPM satellite), analysis of the temporal trend of vegetation health and precipitation was established in order to investigate the impacts of droughts. The results illustrated a significant decreasing trend in precipitation and vegetation across Kenya in the past decades. Monthly precipitation anomalies over both the dry season and wet season have evident troughs and peaks indicating drought events with lack of rainfall. Analyzing the dry season alone in the period from 2016 to 2018, the NDVI anomaly showed a consistent decreasing trend indicating a severe decline in vegetation health and in turn crop production. This decreasing trend of both precipitation and NDVI is strongly correlated with extreme drought events consistently hitting Kenya and other parts of East Africa.

description: Coupling of quantum emitters in a semiconductor relies, generally, on short-range dipole-dipole or electronic exchange type interactions. Consistently, energy transfer between exciton states, that is, electron-hole pairs bound by Coulomb interaction, is limited to distances of the order of 10~nm. Here, we demonstrate polariton-mediated coupling and energy transfer between excitonic states over a distance exceeding 2~$μ$m. We accomplish this by coupling quantum well-confined excitons through the delocalized mode of two coupled optical microcavities. Use of magnetically doped quantum wells enables us to tune the confined exciton energy by the magnetic field and in this way to control the spatial direction of the transfer. Such controlled, long-distance interaction between coherently coupled quantum emitters opens possibilities of a scalable implementation of quantum networks and quantum simulators based on solid-state, multi-cavity systems.

description: West Nile virus (WNV) first appeared in North America during the spring season of 2002, growing to be the most common mosquito borne disease in Ontario, and becoming the primary cause of viral encephalitis. Climate change is hypothesized to increase Ontarian contact with WNV as climatic variables have been studied to amplify bridge vector replication in infected mosquitos. To further investigate this relation, we developed 2 models—Logistic Regression and Decision Tree—to predict WNV occurrence in mosquitos by these factors in Ontario. The Decision Tree model reflected a higher overall accuracy of 100% in training and 93% in testing. Both the Decision Tree model and Logistic Regression model found positive correlations between factors of night temperature, night humidity, NDVI, and rainfall, to the occurrence of mosquito WNV output. While the Logistic Regression model itself, found the occurrence of mosquito WNV cases to have a negative correlation to the factors: wind speed, day humidity, and total precipitation. Our findings can provide useful insight on when to warn the public to take special measures against WNV disease.

description: The region of Central Asia is traditionally assigned an important place in Russia's foreign policy strategy. Considering the vast areas of the Russian state, maintaining security and controlling long borders has always been an uneasy and responsible foreign policy task. In this regard, it was very important for the Russian leadership to find the most favorable geopolitical locations, which, on the one hand, made it possible to contain external threats and, on the other hand, to spread their own influence. One of such outposts of Russia's geopolitical influence was and remains the Central Asian region.

description: The invasive Japanese Mystery Snail (Heterogen japonica) has invaded North American freshwater environments after having been introduced in 1892. The subsequent spread has been attributed to recreational activities. Thus, it is imperative to determine the survival rate of the Japanese Mystery snail when exposed to air in order to understand its invasive ecology and likelihood of introduction to new environments. To do this, adult mystery snails (34-54 mm) were incubated on a diurnal cycle. The temperature during the 12 hours with light was maintained at 32.2℃ while the 12 hours without light was maintained at 21.1℃. Conversely, the juvenile snails (4-9 mm) were given constant light with a consistent temperature of 32.2℃. Fifteen adult snails were pulled every Monday, Wednesday, and Friday, then placed in water to check for mortality. Around 30 juvenile snails were pulled each hour for 24 hours. As of two weeks, adult snails have not shown mortality. The juvenile snails, however, began dying after 18 hours in the incubator (59% mortality). Therefore, juvenile snails would be unable to survive boating and fishing net transportation if exposed to air for an elongated amount of time; whereas, adult snails can survive extensive air exposure.

description: The coefficients of the membrane instantons in the ABJM theory are known to be quadratic polynomials of the chemical potential. We show that, after deforming the ABJM theory into more general superconformal Chern-Simons theories labelled by (q,p) where the original ABJM theory corresponds to (q,p)=(1,1), we can decompose the membrane instanton into three types of non-perturbative effects with constant coefficients independent of the chemical potential. We find that, although these constants contain poles at certain values of q and p including the ABJM case, all of the poles cancel among themselves and the finite quadratic polynomial coefficients are reproduced at these values. This is similar to what happens between the membrane instantons and the worldsheet instantons in the ABJM theory.

description: Проходящие в течение последних 15 лет внутриполитические процессы в Турции будут иметь непосредственное влияние на Центральную Азию. Во-первых, Турция будет все больше выдвигать «фактор Гюлена» в повестку двусторонних отношений с Кыргызстаном и Казахстаном. Во-вторых, в условиях политической нестабильности в Турции, для стран региона особую обеспокоенность вызывают риски, связанные с возвращением центрально-азиатских боевиков через территорию Турции. В-третьих, дальнейшая нормализация отношений между Москвой и Анкарой может стать важным этапом по усилению влияния Анкары в регионе в долгосрочной перспективе. В настоящее время, обе страны являются ключевыми стратегическими и экономическими партнерами для стран Центральной Азии. Вместе с этим, угрозы связанные с дестабилизацией Афганистана и перспективы подключения Турции к китайской инициативе «Экономическому поясу Шелкового пути» будет подпитывать интерес Анкары по расширению взаимодействия с центрально-азиатскими странами в транспортно-логистических и инфраструктурных проектах. Однако, с учетом активной вовлеченности Турции в ближневосточные дела и трансформацией ЕС, ее ключевого торгового партнера, роль Анкары в центрально-азиатских процессах в обозримом будущем будет оставаться ограниченной. Используя обширный методологический инструментарий, автор рассматривает внешнеполитическую концепцию Турции в центральноазиатском регионе с учетом вышеперечисленных факторов.

description: This study compares the travel time and cost of trains and planes to determine their spatial and temporal differences on a national and regional level. It collects the travel time and ticket price for trips between the 50 most populated American cities for (i) different classes (e.g., coach, first class), (ii) different departure times (e.g., morning, afternoon), and (iii) different operators (Delta, Amtrak). This yields an extensive dataset for 2,450 trips. Two findings are discerned when comparing the cheapest trains and flights. First, trains are 41 hours slower than flights on average. The difference is lowest in the Midwest, where trains are on average 31 hours slower than flights, and highest in the Southeast, where they are 43 hours slower. Second, trains are $136.70 more expensive than flights on average. The difference is lowest in the Midwest, where trains are on average $81.31 more expensive than flights, and highest in the Southeast, where they are $169.06 more expensive. The findings echo long-expressed sentiments that trains trail planes and urge larger investments in a new era of rail in America if cutting planet-heating pollution is high on the political agenda.

Year: 2023

description: This study develops a framework for web scraping Google Scholar utilizing user-inputted search queries and advanced search parameters. It confronts and finds solutions to two traditional challenges of web scraping. First, most sites implement anti-bot measures, prompting Completely Automated Public Turing tests to tell Computers and Humans Apart (CAPTCHAs), which block the usage of the website by an automated system. Second, all publicly available solutions to CAPTCHAs in web scraping are either unreliable or expensive. The proposed framework employs the Python package Selenium, resulting in a free and reliable framework to collect data through Google Scholar with the ability to manually bypass CAPTCHAs. It also exports the data into an easily usable format. The outcome of the search queries is extensive and includes information of journals, articles, and authors, publication statistics, and citation data. This contributes to the rapidly growing data extraction practice.

title: The effects of different types and styles of native advertising
Creators: name: Hong, Stacey
Year: 2021

description: Die wachsende Verbreitung von Native Advertising in den Nachrichten birgt die Möglichkeit eine negative Einstellung gegenüber dem Werbenden und dem Herausgeber bei den Lesern hervorzurufen. Dieser Umstand könnte weniger effektive Werbemaßnahmen für die werbenden Sponsoren bedeuten und, was noch schlimmer ist, es könnte das Fundament der Nachrichten als vertrauenswürdige Informationsquelle für Bürger erschüttern. Deshalb wurde in der vorliegenden Arbeit ein faktorielles Experiment mit 2 (Native-Advertising-Typ: kommerziell vs. nicht- kommerziell) x 2 (Native-Advertising-Stil: informativ vs. narrativ) Variablen durchgeführt, um die Auswirkungen unterschiedlicher Native Advertising-Inhalte auf die Einstellung gegenüber des Native Advertising und dem Vertrauen in den Medienanbieter zu ermitteln. Die Ergebnisse von insgesamt 183 Teilnehmern deuten darauf hin, dass Native Advertising, die von einer kommerziellen Organisation gesponsert werden, eher als Werbung wahrgenommen werden und dies zu einem geringeren Vertrauen in die Medienanstalt führen, als wenn sie von einer gemeinnützigen Organisation gesponsert werden. Die Ergebnisse dieser Arbeit könnten Nachrichtenorganisationen als Entscheidungshilfe dienen, wenn es um die Veröffentlichung von Werbeinhalten auf ihren Plattformen geht. Diese Arbeit erweitert die Erkenntnisse über den Einfluss unterschiedlicher Inhalte von Native Advertising auf wichtige Ergebnisvariablen. Theoretische und praktische Implikationen werden in der folgenden Arbeit weiter diskutiert.
description: The growing ubiquity of native advertising in the news media is accompanied with the possibility of negative attitudes toward the advertisement and the publisher. This could mean less effective advertising efforts for the sponsors and even worse, it could shake the foundation of the news media as a trusted source of information for citizens. Recognising this, the current study conducted a 2 (native advertising type: commercial vs. non-commercial) x 2 (native advertising style: informational vs. narrative) factorial between-subjects experiment to determine the effects of varied native advertising content on attitudes toward the native advertisement and trust in the media outlet. Findings from a total of 183 participants suggested that native advertisements sponsored by a commercial organisation are more likely to be recognised as advertising and resulted in lower levels of trust in the media outlet as opposed to when sponsored by a non-profit organisation. These findings could serve as guidelines in news organisations’ decision-making process when determining the publication of advertising content on their platforms. This study advances the knowledge of influence varied content of native advertisements on key outcome variables. Theoretical and practical implications are further discussed in the paper.

description: Crop mapping via remotely-sensed images is growing increasingly important in the agricultural sector; oftentimes machine learning is employed to expedite the process of creating these maps. However, the results of traditional machine learning approaches, such as random forest and SVM, can be noisy: these methods are applied to satellite imagery pixel-by-pixel and thus can result in misclassified pixels within a cropland unit. This can be improved upon in postprocessing – by using computer vision models to automatically segment the original satellite image, we can identify the boundaries of each cropland unit and use this data to clean up the image. Specifically, our experiment goes through each segmented area, finding the mode of the cropland values and reclassifying any erroneous pixels in that area to this value. We used Meta’s Segment Anything Model (SAM) to perform image segmentation: this system has zero-shot generalization, meaning that it can accurately segment images that it has never encountered in training. Using Google Earth Engine as the primary data analysis platform, we applied this model to two key agricultural regions in the United States as study areas (one in California’s Central Valley and the other in the U.S. Corn Belt) to assess the utility of this approach. As compared with the U.S. Department of Agriculture’s Cropland Data Layer, the accuracy of the crop maps improved by X% in the California study area and Y% in the Illinois area. We conclude that this method can be used to improve crop map accuracy and could be applied across the entire United States, lending itself to more accurate crop yield estimation and thus more informed agricultural decisions.

Renormalon Effects in Quasi Parton Distributions

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the renormalon ambiguity from bubble-chain diagrams in the isovector unpolarized quasi-parton distribution function (PDF) of a hadron. We confirm the assertion by Braun, Vladimirov and Zhang (arXiv:1810.00048) that the leading IR renormalon ambiguity is formally an $\mathcal{O}(Λ^2_{QCD}/x^2P_z^2)$ effect, with $x$ the parton momentum fraction and $P_z$ the hadron momentum, together with a new $\mathcal{O}(δ(x)Λ^2_{QCD}/P_z^2)$ contribution such that the quark number is conserved. This implies the convergence of the perturbative matching kernel between a quasi-PDF and a PDF would eventually fail for small $x$. However, in both the R-scheme designed to cancel the leading IR renormalon and the typically used RI/MOM scheme in lattice QCD for the same quasi-PDF, we find good convergence in the kernel based on three-loop bubble-chain diagram analyses. These results are encouraging for the quasi-PDF program. However, firm conclusions can only be drawn after the complete higher loop QCD calculations are carried out.
