Role of Mathematics in the Development of Society" - A Perspective Study
Authors: Srinivasulu C
Published: July 2024

A "society" is a group of individuals who have developed a long-term bond or an immense social gathering that is governed by the same government and cultural standards as the group in question. An economic, social, and/or industrial infrastructure is established as a result of the collaboration of people from many origins and cultures. Because man is a social animal, he and his fellow humans must collaborate in order to survive. A lot of group work helps with social skills. Social skills can be learned by working together on tasks with other people.

Artificial Intelligence, Post-Work and Music Labor
Authors: Atanasovski Srđan
Published: July 2024

The recent – purportedly rapid – development of AI tools has again resurrected the actuality of post-work u-/dystopias. Drawing on discursive topoi which have become popular since the post-WW2 automatization surge, AI post-work now advances into the field of white-collar labor, but also creative, artistic, and even music labor. In this paper I aim to analyze the emergent arrival of the post-work thesis into music labor. I will draw on prominent critics of automatization, AI and post-work discourses, such as Pierre Naville, Aaron Benanav and Jason Resnikoff, to show that these discourses are not only unsubstantiated, but are instrumentalized in order to depreciate the value of concrete labor in music production.
Question of Knowledge in Active Usage of AI Tool “ChatGPT”
Authors: Tiro Hana
Published: July 2024

The paper analyzes the outcomes and usefulness of ChatGPT after being prompted by the user to collect information in the field of arts and humanities. The research questions whether AI methodologies make it easier to find precise sources, or whether the methodologies move us away from the topic we are supposed to know how to precisely communicate. Another question that naturally surfaces is the copyright of the generated text, taken that the tool itself is a storage of already published papers and articles. As such, if we use that information, do we mimic someone else’s work? Materials used in research are forums, academic papers, and ChatGPT results themselves. The research method is based on comparing forum discussions and showing different sides of the ethical usage of ChatGPT. There is a possibility of two different approaches, one confirming copyright infringement, and the other arguing how AI tools are helpful. As we are currently ending the first quarter of the 21st century, learning about the newly emerged AI tools is our obligation.

Socioeconomic challenges and opportunities in renewable energy transition
Authors: Nwankwo Charles Uzondu  , Dominic Dummene Lele
Published: July 2024

The global transition to renewable energy is a multifaceted endeavor that entails profound socioeconomic transformations. This study aimed to explore the socioeconomic challenges and opportunities inherent in this transition. By leveraging a comprehensive review of existing literature and case studies, this research provides insights into the economic, social, technological, and policy dimensions of renewable energy adoption. The study employed a mixed-methods approach, combining qualitative analysis of policy frameworks with quantitative assessment of economic impacts. Key findings indicate that while renewable energy technologies, such as solar and wind, are increasingly cost-competitive, high initial capital costs and long payback periods remain significant barriers. Social and cultural resistance also poses challenges, particularly in communities with strong ties to traditional energy sources. Policy inconsistencies and regulatory uncertainties further complicate the adoption of renewable energy technologies. Conversely, the study highlights numerous opportunities. Renewable energy deployment can drive substantial job creation, stimulate local economies, and enhance energy security by diversifying energy sources. Technological advancements in energy storage and smart grids are crucial for integrating renewable energy into existing systems, thereby ensuring reliability and stability. Effective policy frameworks, such as feed-in tariffs and carbon pricing, are essential for fostering investment and innovation in the renewable energy sector. The study concludes that a holistic approach, integrating economic incentives, social engagement, and robust policy frameworks, is vital for overcoming challenges and maximizing the benefits of renewable energy. Recommendations for future research include exploring innovative financial instruments, advancing energy storage technologies, and enhancing public engagement to increase social acceptance of renewable energy projects.

Effect of peanut-skin fortification on oil separation and consumer acceptance of sesame butter
Authors: Manyisa Vimbainashe Christine , Nyakudya Eljah , Benhura Chakare , Dhliwayo Lawrence
Published: July 2024

Background: Sesame butter offers a rich source of health benefits, but its commercial viability is hampered by oil separation during storage. Aims: This study aimed to develop a sesame butter formulation with improved oil retention capacity using peanut skins (PS) as a natural thickening agent, while also evaluating consumer acceptance of the resulting product. Material and Methods: Sesame butter was prepared from roasted sesame seeds. The formulation was then reformulated with the incorporation of PS at varying concentrations (0.0%, 0.5%, 1.0%, 2.0%, 5.0% and 10.0%). Oil separation in these formulations was monitored throughout a storage period of 63 days, with measurements recorded at regular intervals (1, 3, 5, 7, 14, 21, 28, 35, 42, 49, 56 and 63 days). To assess consumer acceptability, 50 untrained panelists evaluated the sensory attributes (flavor, texture, and overall acceptance) of the sesame butter formulations using a 9-point hedonic scale. Results: Consumer acceptance of the sesame butter was primarily influenced by the formulation's sensory characteristics, particularly flavor and color. Texture did not significantly impact overall acceptance (p = 0.975). Notably, the degree of oil separation significantly decreased (p = 0.00) with increasing PS concentration. A marked reduction in oil separation occurred after 14 days of storage. Formulations containing 10.0% and 5.0% PS exhibited the most effective oil retention, while the 1.0% PS formulation received the highest consumer ratings for flavor, texture, and overall acceptability. Conclusion: This study demonstrates the potential of peanut skins as a viable food additive to enhance oil retention capacity and consumer acceptance of sesame butter. Notably, the optimal PS concentration for improved functionality and consumer preference appears to be at a lower level (1.0%). This finding suggests the potential for effective oil separation control without compromising consumer perception of the product.

Climate and ice sheet dynamics in Patagonia throughout marine isotope stages 2 and 3
Authors: Castillo-Llarena Andrés , Retamal-Ramírez Franco , Bernales Jorge , Jacques-Coper Martín , Prange Matthias , Rogozhina Irina
Published: July 2024

Abstract. During the Last Glacial Maximum (LGM, ∼ 23 000 to 19 000 years ago), the Patagonian Ice Sheet (PIS) covered the central chain of the Andes between ∼ 38 to 55° S. Existing paleoclimate evidence – mostly derived from glacial landforms – suggests that maximum ice sheet expansions in the Southern Hemisphere and Northern Hemisphere were not synchronized. However, large uncertainties still exist in the timing of the onset of regional deglaciation and its major drivers. Here we present an ensemble of numerical simulations of the PIS during the LGM. We assess the skill of paleoclimate model products in reproducing the range of atmospheric conditions needed to enable an ice sheet growth in concordance with geomorphological and geochronological evidence. The resulting best-fit climate product is then combined with records from southern South America offshore sediment cores and Antarctic ice cores to drive transient simulations throughout the last 70 ka using a glacial index approach. Our analysis suggests a strong dependence of the PIS geometry on near-surface air temperature forcing. Most ensemble members underestimate the ice cover in the northern part of Patagonia, while tending to expand beyond its constrained eastern boundaries. We largely attribute these discrepancies between the model-based ice geometries and geological evidence to the low resolution of paleoclimate models and their prescribed ice mask. In the southernmost sector, evidence suggests full glacial conditions during marine isotope stage 3 (MIS3, ∼ 59 400 to 27 800 years ago), followed by a warming trend towards MIS2 (∼ 27 800 to 14 700 years ago). However, in northern Patagonia, this deglacial trend is absent, indicating a relatively consistent signal throughout MIS3 and MIS2. Notably, Antarctic cores do not reflect a glacial history consistent with the geochronological observations. Therefore, investigations of the glacial history of the PIS should take into account southern midlatitude records to capture effectively its past climatic variability.
A satellite-based analysis of semi-direct effects of biomass burning aerosols on fog and low cloud dissipation in the Namib Desert
Authors: Mass Alexandre , Andersen Hendrik , Cermak Jan , Formenti Paola , Pauli Eva , Quinting Julian
Published: July 2024

Abstract. In the Namib Desert fog is the only regular water input and thus a crucial water source for its fauna and flora. Each year between June and October, in some synoptic settings, absorbing biomass burning aerosols (BBA) are overlying the stratocumulus clouds in the adjacent Southeast Atlantic, and sometimes are reaching the coastal fog and low clouds (FLCs) in Namibia. In this study, a novel 15-year data set of geostationary satellite observations of FLC dissipation time in the Namib Desert is used together with reanalysis data in order to better understand possible semi-direct effects of BBA on the dissipation of FLCs in the Namib. This is done by investigating both FLC dissipation time and synoptics depending on BBA loading. It is found that FLC dissipation time is significantly later on high BBA loading days. BBA are transported to the Namib along moist free-tropospheric air by a large-scale anticyclonic recirculation pattern. At the surface, the associated longwave heating strengthens a continental heat low, which modifies the circulation and boundary layer moisture along the coastline, complicating the attribution of BBA effects. During high BBA days, the vertical profiles of the temporal development of air temperatures highlight contrasting day and nighttime processes modifying the local inversion. These processes are thought to be driven by greenhouse warming by the moisture in the BBA plumes and BBA absorption (only during daytime). A statistical learning framework is used to quantify meteorological and BBA influences on FLC dissipation time. The statistical model is able to reproduce the observed differences in FLC dissipation time between high and low BBA days and attributes these differences mainly to differences in circulation, boundary layer moisture and near-surface air temperature along the coastline. However, the model is underfitting and is not able to reproduce the majority of the FLC dissipation variability. While the model does not suggest that BBA patterns are important for FLC dissipation, the findings show how the moist BBA plumes modify local thermodynamics to which FLC dissipation is shown to be sensitive. The findings highlight the difficulties of disentangling meteorological and aerosol effects on cloud development using observations.
Glacier-level and gridded mass change in the rivers' sources in the eastern Tibetan Plateau (ETPR) from 1970s to 2000

Published: July 2024

Abstract. The highly glacierized eastern part of the Tibetan Plateau is the key source region for seven major rivers: Yangtze, Yellow, Lancang-Mekong, Nu-Salween, Irrawaddy, Ganges, and Brahmaputra rivers. These rivers are vital freshwater resources for more than one billion people downstream for their daily life, irrigation, industrial use, and hydropower. However, the glaciers have been receding during the last decades and are projected to further decline which will profoundly impact the water availability of these larger river systems. Although few studies have investigated glacier mass changes in these river basins since the 1970s, they are site and temporal specific and limited by data availability. Hence, knowledge of glacier mass changes is especially lacking for years prior to 2000. We therefore applied digital elevation models (DEMs) derived from large scale topographic maps based on aerial photogrammetry from the 1970s and 1980s and compared them to the Shuttle Radar Topography Mission (SRTM) DEM to provide a complete picture of mass change of glaciers in the region. The mass changes are presented on individual glacier bases with a resolution of 30 m and are also aggregated into gridded formats at resolutions of 0.1° and 0.5°. Our database consists of 13117 glaciers with a total area of ~21695 km2. The annual mean mass loss of glaciers is -0.30 ± 0.12 m w.e. in the whole region. This is larger than the previous site-specific findings, the surface thinning increases on average from west to east along the Himalayas-Hengduan mountains with the largest thinning in the Irrawaddy basin. Comparisons between the topographic map-based DEMs and DEMs generated based on Hexagon KH-9 metric camera data for parts in the Himalayas demonstrate that our dataset provides a robust estimation of glacier mass changes. However, the uncertainty is high in high altitudes due to the saturation of aerial photos over low contrast areas like snow surface on a steep terrain. The dataset is well suited for supporting more detailed climatical and hydrological analyses and is available at https://doi.org/10.11888/Cryos.tpdc.301236 (Liu et al., 2024).
Scientific logic and spatio-temporal dependence in analyzing extreme-precipitation frequency: negligible or neglected?
Authors: Serinaldi Francesco
Published: July 2024

Abstract. Statistics is often misused in hydro-climatology, thus causing research to get stuck on unscientific concepts that hinder scientific advances. In particular, neglecting the scientific rationale of statistical inference results in logical and operational fallacies that prevent the discernment of facts, assumptions, and models, thus leading to systematic misinterpretations of the output of data analysis. This study discusses how epistemological principles are not just philosophical concepts but also have very practical effects. To this aim, we focus on the iterated underestimation and misinterpretation of the role of spatio-temporal dependence in statistical analysis of hydro-climatic processes by analyzing the occurrence process of extreme precipitation (P) derived from 100-year daily time series recorded at 1106 worldwide gauges of the Global Historical Climatology Network. The analysis contrasts a model-based approach that is compliant with the well-devised but often neglected logic of statistical inference and a widespread but theoretically problematic test-based approach relying on statistical hypothesis tests applied to unrepeatable hydro-climatic records. The model-based approach highlights the actual impact of spatio-temporal dependence and a finite sample size on statistical inference, resulting in over-dispersed marginal distributions and biased estimates of dependence properties, such as autocorrelation and power spectrum density. These issues also affect the outcome and interpretation of statistical tests for trend detection. Overall, the model-based approach results in a theoretically coherent modeling framework where stationary stochastic processes incorporating the empirical spatio-temporal correlation and its effects provide a faithful description of the occurrence process of extreme P at various spatio-temporal scales. On the other hand, the test-based approach leads to theoretically unsubstantiated results and interpretations, along with logically contradictory conclusions such as the simultaneous equi-dispersion and over-dispersion of extreme P. Therefore, accounting for the effect of dependence in the analysis of the frequency of extreme P has a huge impact that cannot be ignored, and, more importantly, any data analysis can be scientifically meaningful only if it considers the epistemological principles of statistical inference such as the asymmetry between confirmatory and disconfirmatory empiricism, the inverse-probability problem affecting statistical tests, and the difference between assumptions and models.
Measuring prairie snow water equivalent with combined UAV-borne gamma spectrometry and lidar
Authors: Harder Phillip , Helgason Warren D. , Pomeroy John W.
Published: July 2024

Abstract. Despite decades of effort, there remains an inability to measure snow water equivalent (SWE) at high spatial resolutions using remote sensing. Passive gamma ray spectrometry is one of the only well-established methods to reliably remotely sense SWE, but airborne applications to date have been limited to observing kilometre-scale areal averages. Noting the increasing capabilities of unoccupied aerial vehicles (UAVs) and miniaturization of passive gamma ray spectrometers, this study tested the ability of a UAV-borne gamma spectrometer and concomitant UAV-borne lidar to quantify the spatial variability of SWE at high spatial resolutions. Gamma and lidar observations from a UAV (UAV-gamma and UAV-lidar) were collected over two seasons from shallow, wind-blown, prairie snowpacks in Saskatchewan, Canada, with validation data collected from manual snow depth and density observations. A fine-resolution (0.25 m) reference dataset of SWE, to test UAV-gamma methods, was developed from UAV-lidar snow depth and snow survey snow density observations. The ability of UAV-gamma to resolve the areal average and spatial variability of SWE was promising with appropriate flight characteristics. Survey flights flown at a velocity of 5 m s−1, altitude of 15 m, and line spacing of 15 m were unable to capture the average or spatial variability of SWE within the uncertainty of the reference dataset. Slower, lower, and denser flight lines at a velocity of 4 m s−1, altitude of 8 m, and line spacing of 8 m were able to successfully observe areal average SWE and its variability at spatial resolutions greater than 22.5 m. Using a combination of UAV-based gamma SWE and UAV-based lidar snow depth improved the spatial representation of SWE substantially and permitted estimation of SWE at a spatial resolution 0.25 m with a ± 14.3 mm error relative to the reference SWE dataset. UAV-borne gamma spectrometry to estimate SWE is a promising and novel technique that has the potential to improve the measurement of shallow prairie snowpacks, and when combined with UAV-borne lidar snow depths, can provide fine-resolution, high-accuracy estimates of prairie SWE. Research on optimal hardware, data processing, and interpolation techniques is called for to further improve this remote sensing product and explore its application in other environments.

Abstract. In polar regions, sea ice is a crucial mediator of the interaction between Earth's atmosphere and oceans. Its formation and breakup is intimately connected with large-scale climatic processes, local weather patterns, and the use of sea ice in coastal Arctic regions by Indigenous people. In order to investigate the physical phenomena at the heart of this process, a set of targeted, intensive observations were made over spring sea ice melt and breakup in Kotzebue Sound, Alaska. These observations were planned and executed through a collaborative effort in which an Indigenous Elder advisory council from Kotzebue and scientists participated in co-production of hypotheses and observational research, including a stronger understanding of the physical properties of sea ice during spring melt. Here we present the results of observations performed using high-endurance, fixed-wing uncrewed aerial vehicles (UAVs) containing custom-built scientific payloads. Repeated flights over the measurement period captured the early stages of the transition from a white, snow-covered state to a broken-up, bare blue-green state. We found that the reflectance of sea ice features depends strongly on their size. Snow patches get darker as they get smaller, an effect owed to the geometric relationship between the bright interior and the darker, melting feature edges. Conversely, bare patches get darker as they get larger. For the largest ice features observed, bare blue-green ice patches were found to be ≈ 20 % less reflective than average across all observational cases, while large snowy white ice patches were found to be ≈ 20 % more reflective than that same average.
ASEAN Digital Economy Framework Agreement (DEFA): Opportunities and Challenges for Vietnam
Authors: Zulianto Mukhamad
Published: July 2024

Vietnam is a key player in the ASEAN digital economy, focusing on digital integration and collaboration. The ASEAN Digital Integration Framework Action Plan 2019-2025 and the ASEAN Digital Masterplan 2025 outline the policy landscape for digital integration. ASEAN member states have signed agreements and memorandums of understanding to foster cooperation in the digital economy. However, challenges such as skill gaps, cyber security, and regulatory gaps need to be addressed. The Digital Economy Partnership Agreement (DEPA) is seen as a key venue for increasing cooperation and consistency of digital trade rules in the Asia-Pacific region. ASEAN has been actively involved in global and regional discussions on cybersecurity, aiming to galvanize regional states into collective action against malicious cyber activities. The 20th Asian Economic Community council adopted the Bandar Seri Begawan Roadmap (BSBR) to accelerate ASEAN's economic recovery and digital economy integration in October 2021. This article also applies a qualitative method with secondary data. Modular Digital Economy Agreements (DEA) may be an appropriate model for facilitating digital trade alignment with international trading partners.

Verificou-se que as ações fomentadas pelas entidades futebolísticas impactaram positivamente ao trazer oportunidades para um número maior de mulheres, mas não garantiu melhorias nas condições de atuação das jogadoras e não remeteu a profissionalização no futebol de mulheres, especialmente para equipes com baixo capital simbólico, localizadas fora dos centros futebolísticos.

The goal of every service provided by a government or private agency, organization, or company, of course, is to offer the best possible service to its customers. Non-ministerial government organizations such as the BKN IT Infrastructure Directorate must ensure that they provide the best service to all work units and employees within the State Civil Service Agency. Therefore, it is necessary to monitor the quality of services that have been provided. One method is to carry out an IT infrastructure service satisfaction survey. Currently, the BKN Information Technology Infrastructure Directorate has conducted a customer satisfaction survey. However, the process still uses the conventional method, which starts from informing the survey and completing the data to the process of making reports which are done manually. This research was carried out by searching for theories and journals related to satisfaction ratings. System design is carried out using the Codeigniter 3 Framework combined with the Extreme Programming (XP) system development method where this development method is suitable for application in government agencies and places where there are few application developers. By using the CodeIgniter 3 Framework and the XP development method, it is hoped that the development of this application will run smoothly and quickly so that the application can be implemented immediately.
