BLOCKCHAIN REVOLUTION: Intensifying Data Protection and Blockchain based IPR Systems
Authors: - Sriraghavi S
Published: November 2024

Blockchain Technology, also known as Distributed Ledger System, collects the data stored in enciphered blocks, which are closely linked to hash pointers.
These hash pointers, links one block to another, which together forms a chain, known as the Block Chain.
Blockchain and any other form of distributed ledger technologies, creates a trustworthy and a transparent record, by allowing multiple parties to a transaction to substantiate what will be entered in the ledger advanced.
It has a multi-faceted utilization, where it can reserve and protect any type of data and can also, encrypt the Data in stored in Independent Data Blocks. These chains have an unaccompanied and unassisted time snaps, which secures the indivisible data, collected from consumers. This distributed ledger technology, creates a secure, time-stamped and immutable chain of information, which prevents counterfeiting and ensures that, the IP systems, are properly being traced.
Blockchain, also supports smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. Smart contracts can automate the licensing and royalty payments for IP, ensuring that creators are compensated fairly and transparently.
It also facilitates the creation of decentralized marketplaces for buying, selling, and licensing Intellectual Property. Thus, this reduces the need for intermediaries and can also lower transaction costs, which increases the access to IP for potential buyers and licensees.
Therefore, where a particular society is adapting up, to explore the unexplored, protection of Intellectual Property by using Blockchain, could play a vital role in the development and expansion of the Indian Economy.
Thus, This research paper, aims to spell out the role of Block Chain technology, in protecting the data embedded in Intellectual Property Rights, which ensures to create a secure, transparent and a decentralized protection, for Intellectual Property Rights.

Political Conflicts in Hikayat Seri Kelantan from the Perspective of Theory of Conflict Behaviour
Authors: Idzwan Faris , Jamian Muhd. Norizam
Published: November 2024

Hikayat Seri Kelantan (HSK) is one of Kelantan’s traditional Malay historiographical texts. As a historical literary text, this hikayat comprises various conflicts involving the Malay kingdom and its external powers. However, most studies on HSK focus more on the issue of war without discussing political conflicts as a whole. Therefore, this article discusses the political conflicts in HSK by outlining two objectives, which are to elaborate on the conflicts in HSK and to analyse the causes of the conflicts according to the theory of conflict behaviour. This article utilised the HSK manuscript edited by Mohd. Taib Osman (2004) as its primary source, while data collection was done using library research. Close reading strategy and analysis of descriptive text were applied in data analysis based on the theory of conflict behaviour by Bartos and Wehr (2002). The findings of this study showed nine events of political conflicts that could be categorised into four issues, which are: (1) the issue of tyrannical reign; (2) the issue of state sovereignty from external powers; (3) the issue of territorial expansion; and (4) the issue of position and power struggle in reign. The findings also revealed that disputes over resources comprising land or territory, power, and prestige are the premises for political conflicts in HSK. This study proves that HSK is a sociocultural document that has recorded various political conflicts of the Malay kingdom in Kelantan.

Authors: Kong Suik Fern , Mohd Matore Mohd Effendi @ Ewan
Published: November 2024

STEM approaches are able to help the students to think creatively, systematically and logically. There are two major issues that need to be discussed which are the low level achievement of students in Science and Mathematics through international assessments of TIMSS and PISA and students were less interested in the conventional teaching and learning process. The primary goal of this study is to analyse the articles that are related to STEM approach in teaching and learning and develop conceptual framework based on the analysis carried out. Two databases which are SCOPUS and ERIC were used in screening the articles. A systematic literature review procedure includes the search strategies, selection criteria, selection process, data collection and data analysis from the articles obtained. There are 31 articles that fulfill the criteria of selection such as the year of publication and types of language. The results of the analysis showed that inquiry-based learning has the highest number of referrals followed by project-based learning, multi-mode learning, problem-based learning and cooperative learning. The conceptual framework was developed based on the STEM approaches that are frequently used in past studies which included inquiry-based learning, project-based learning, multi-mode learning, problem-based learning and cooperative learning. Therefore, further researches are needed to examine whether cooperative learning can be incorporated into the established conceptual frameworks.
A case for the reconceptualisation of autism in Vietnam
Authors: Boyle Leoni , Bailey Julie
Published: November 2024

This integrative literature review presents the analysis of social stigmas surrounding autism as being a valuable and effective way of understanding current conceptualisations of autism in Vietnam. Social stigmas are negative perceptions directed towards groups within a population who are perceived to differ from what is considered the societal norm, and are explored in this integrative literature review through the thematic analysis of articles, blog posts, and published interviews. This review explores how social stigmas are developed and maintained, framed within Bronfenbrenner’s Ecological Systems Theory, and provides a conceptual framework to understand how an increase of tolerance for autism can be encouraged. Encouraging tolerance through the tackling of social stigma maintenance can be achieved in a culturally sensitive manner, shown through the consideration of individual experiences of those within the autism community in Vietnam. Other previously stigmatised topics have been shown to have changed in recent Vietnamese society as now being more tolerated and accepted within society, suggesting that internal and external influences can bring about an increase in tolerance. The encouragement of a more flexible and tolerant view of autism could be brought about through a combined effort between the State and the media, education and the service sector, whilst prioritising the opinions of those within the autism community in Vietnam. A holistic approach to increasing tolerance, such as through the framework explored in this review, must be developed in order to be successful.

Authors: Şendil Çağla Öneren
Published: November 2024

This study aims to examine preschool teachers' compassion and fear of compassion. The sample of this survey study consisted of 274 preschool teachers. Personal Information Form, Adult Compassion Scale, and Fear of Compassion Scale were used as data collection tools. Data analysis showed that the compassion level of the preschool teachers was high whereas their fear of compassion level was low. It was also found that the compassion of preschool teachers did not differ significantly based on their gender, age, marital status, educational level, having children, having a pet, having someone to care for at home other than children and their place of residence. Emotional compassion level of preschool teachers who were married and had children was higher than the emotional compassion level of their colleagues who were single and did not have any children. Compassion level of teachers who had 6 to 10 year-professional seniority was significantly higher than their colleagues who had 0 to 5 year-professional seniority. It was found that the fear of compassion level of the preschool teachers did not differ significantly based on their demographic characteristics. Also, a negative significant relationship was found between preschool teachers’ compassion and their fear of compassion. Based on the research findings, it can be suggested that, preschool teachers can be trained on compassion-based activities and compassion can be integrated into daily activities in preschool classrooms. Transfering their knowledege on compassion as a behavior to their classroom activities will help children to take those acts as a role model.
Enactments of Distributed Pedagogical Leadership Between Early Childhood Centre Directors and Deputy Directors in Norway
Authors: Bøe Marit , Hognestad Karin
Published: November 2024

This study aims to investigate how early childhood directors and deputy directors describe their enactments of distributed pedagogical leadership. An interpretive qualitative study was conducted by way of semi-structured individual interviews and job-descriptions of six participants. Distributed leadership frameworks that involve multiple persons enacting pedagogical leadership in interdependent ways, inform the study. The findings of this study illustrate that enactments of distributed pedagogical leadership between ECE directors and deputy directors occur both by leading together where they enact the same leadership task and where they work separately with tasks they have divided between them. Additionally, shared authority, dialogue on pedagogical development, support and division of tasks show various forms of distributed pedagogical leadership enactments. The study highlights some implications for further attention to take benefit from distributed pedagogical leadership. This is important as distributive leadership is seen to increase the capacity of pedagogical leadership through collaboration to deal with challenges and high workload resulting from new requirements and changes.

Implikasi Pandemik Covid-19 Terhadap Golongan Belia Islam Di Malaysia
Authors: Hassan Shahir Akram
Published: November 2024

Various implications are starting to be felt as a result of the Covid-19 pandemic crisis that has hit the world. All levels of society are affected by the pandemic, especially the youth because this group is closely related to the three main sectors of the country, which is health, economy, and education. According to the Department of Statistics Malaysia (DOSM), the unemployment rate in Malaysia remains at 3.6 percent in December 2022. This unemployment rate is still considered high compared to before the pandemic. Based on these statistics, two questions have arisen. First, are the Muslim youth, the majority of the unemployed in Malaysia? And has the pandemic affected the youth job market? Therefore, to answer the question, this paper has three objectives. First, identify the percentage of youth unemployment in Malaysia; second, identify the percentage of the post-pandemic youth job market and third, analyse the implications of the Covid-19 pandemic on youth in Malaysia; This document study was conducted by applying qualitative methods using secondary data and then analysed using content analysis methods. The findings have shown that the 15–30-year-old youth group is the second highest unemployed group in Malaysia. Almost 40% of the entire labour force in Malaysia consists of youth. However, the pandemic crisis has limited opportunities for youth to choose jobs commensurate with their skills and qualifications.

Published: November 2024

The genus Piper is among the most important genera in the Piperaceae family. It is known for several medicinally and economically important species that have been used throughout their native range. Piper species have great diversity in the world’s tropical regions and are represented mainly by aromatic shrubs and trees with significant production of essential oils. The present study reports the chemical composition of the essential oil of Piper penangense and its radical scavenging activity. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The antioxidant activity of the essential oil was determined using DPPH free radical scavenging assay. A total of 12 components (84.5%) were successfully identified, which were characterized by humulene epoxide II (31.9%), caryophyllene oxide (9.9%), muurola-4,10(14)-dien-1β-ol (9.1%) and β-ionone (8.3%). The essential oil showed significant activity towards DPPH radical scavenging (concentration 1,000 μg/mL) with a percentage inhibition of 72.5%. This study may provide valuable information and indications for further exploring the potential nutraceutical and pharmaceutical applications of the Piper species.
New Bounds for Odd Colourings of Graphs
Authors: Dai Tianjiao , Ouyang Qiancheng , Pirot François
Published: November 2024

Given a graph $G$, a vertex-colouring $\sigma$ of $G$, and a subset $X\subseteq V(G)$, a colour $x \in \sigma(X)$ is said to be odd for $X$ in $\sigma$ if it has an odd number of occurrences in $X$. We say that $\sigma$ is an odd colouring of $G$ if it is proper and every (open) neighbourhood has an odd colour in $\sigma$. The odd chromatic number of a graph $G$, denoted by $\chi_o(G)$, is the minimum $k\in\mathbb{N}$ such that an odd colouring $\sigma \colon V(G)\to [k]$ exists. In a recent paper, Caro, Petruševski and Škrekovski conjectured that every connected graph of maximum degree $\Delta\ge 3$ has odd-chromatic number at most $\Delta+1$. We prove that this conjecture holds asymptotically: for every connected graph $G$ with maximum degree $\Delta$, $\chi_o(G)\le\Delta+O(\ln\Delta)$ as $\Delta \to \infty$. We also prove that $\chi_o(G)\le\lfloor3\Delta/2\rfloor+2$ for every $\Delta$. If moreover the minimum degree $\delta$ of $G$ is sufficiently large, we have $\chi_o(G) \le \chi(G) + O(\Delta \ln \Delta/\delta)$ and $\chi_o(G) = O(\chi(G)\ln \Delta)$. Finally, given an integer $h\ge 1$, we study the generalisation of these results to $h$-odd colourings, where every vertex $v$ must have at least $\min \{\deg(v),h\}$ odd colours in its neighbourhood. Many of our results are tight up to some multiplicative constant.

Published: November 2024

We completely describe the order ideal (resp. antichain) toggleability space for general fences: the space of statistics which are linear combinations of order ideal (antichain) indicator functions and equal to a constant plus a linear combination of toggleability statistics. This allows us to strengthen some homomesies under rowmotion on fences proven by Elizalde et al. and prove some new homomesy results for combinatorial, piecewise-linear, and birational rowmotion.
Análisis de la articulación territorial en la implementación de políticas agrícolas: Un estudio del proceso de territorialización en la provincia de Santa Elena
Authors: Sánchez Pincay María Fernanda
Published: November 2024

La investigación realizada en la provincia de Santa Elena, Ecuador, examina la implementación de políticas agrícolas a través del Proyecto Integral de Desarrollo Agrícola, Ambiental y Social de Forma Sostenible del Ecuador (PIDAASSE). Este proyecto, iniciado en 2012, buscaba revertir la pobreza, baja producción y migración interna en la región, caracterizada por tierras desérticas y un alto nivel de pobreza. Sin embargo, la ejecución de PIDAASSE enfrentó desafíos debido a la falta de coordinación entre los actores locales y estatales, lo que afectó la articulación territorial. La exclusión de los actores locales en el diseño del proyecto y la inflexibilidad del Estado generaron fisuras organizativas y expectativas no cumplidas. Este estudio concluye que la territorialización de la política pública debe considerar las heterogeneidades del territorio y las competencias de los actores locales para evitar la superposición de entidades y mejorar la gobernanza multinivel, de modo que se promuevan acciones colectivas efectivas (Sosa, 2012; Carrión et al., 2019).

Published: November 2024

The primary objective of this analysis is to examine the fluctuations in stock prices post dividend distribution, and to evaluate how dividends affect stock performance over a one-year period following their allocation. Statistical analysis using the Paired Sample T-Test is employed to assess time series data in this study. The sample used consists of seven banking issuers, namely BBCA, BBNI, BBRI, BMRI, BTPN, MEGA, and BNGA. The study findings suggest that there is a slight decrease in the performance of banking stock prices the day following the dividend cumdate, though not enough to be considered significant.   However, a noticeable difference in share price performance among banking issuers is evident between three months and a year. This was obtained after conducting a paired sample t-test with a result of 0.032. The contraction of stock price performance at cum date in some companies at a certain time, resulting in stock prices falling within a few days. Some of the decline in stock prices after the cum date occurred only a few days or even less than one month, but there were several companies that experienced a longer decline or tended to experience a negative trend for a long time.

‘When you touch plastic, you touch yourself’: material and self in the work of Senga Nengudi
Authors: Elson-Enriquez Isabel
Published: November 2024

This article traces and analyses Senga Nengudi’s use of plastic as a medium in her sculpture and performance of the late 1960s and 1970s. Plastic reappears constantly throughout Nengudi’s oeuvre, a choice most often passed over as merely an economic or logistical one, plastic being both cheap and ubiquitous. In this article, I push against this too-easy explanation, arguing that while it might have started as a material of convenience and low cost, plastic became the medium by which Nengudi could articulate evolving attitudes towards the body. In her earliest work, plastic appears as a playful material, facilitating physical interaction with her viewers, or ‘activators’, as she often described them. But after years working with plastics, Nengudi also embraced the metaphorical implications of the material, recognizing that the qualities that facilitated viewer engagement could also communicate her own corporeal and psychic experience.
The force of plastic: a dive on to the (dis)enchanting inflatables of the Eventstructure Research Group
Authors: Kok Annemarie
Published: November 2024

The members of the Eventstructure Research Group (ERG) pioneered inflatable art and design in the late 1960s. Attracted to the qualities of plastic, the group discovered that it could be glued or welded, filled with air, and used in sculptural and architectural ways. With their soft and light air-filled plastic structures, ERG rejected the ‘hard’ and heavy materials traditionally associated with sculpture and architecture. Significantly, their plastic structures were meant to be touched, moved and interacted with by their audiences. In this way, they pushed – or softened – the boundaries of art and design. This article examines the role and force of plastic in the context of the inflatable and participatory projects of ERG in the 1960s and 1970s. With the help of the concept of ‘vibrant matter’ as developed by Jane Bennett, I explore what plastic enables or disables in relation to artistic practice and its reception in the work of ERG – for both artists and audience members. Specifically, I discuss the social and political effects of the use of this material in order to examine the ‘politics of plastic’ in their artistic production.

Authors: Sánchez Carlos , Cajas Mildred , Calvopiña Paola , Ortega Andrés
Published: November 2024

The objective of the research was to design and simulate the lateral/directional dynamics control of an aircraft’s autopilot system to automate the landing approach execution, complying with the requirements of the Instrument Landing System (CAT III C). The design methodology involved integrating a Linear Quadratic Regulator (LQR) with Affine Parameterization techniques to create a robust control system. The prototype was developed using Matlab and simulated in Simulink. Through various simulations, adjustments were made to the Q and R matrices of the LQR controller based on Bryson’s rule, allowing the system to adapt to the nonlinearities and dynamic constraints of the aircraft model. These adjustments included modifying the lateral attitude control parameters to achieve the desired damping factors and time constants, ensuring flight quality standards according to MIL-8785C. Validation under real conditions through a flight simulator confirmed the control system’s effectiveness under various operational conditions. The controllers are able to maintain the aircraft’s alignment with the runway centerline, even in the presence of external disturbances, thus demonstrating the system’s robustness and reliability. The methodologies and results provide a solid foundation for future improvements and comparative analyses of autopilot systems within CAT III C requirements.

We analyze Spitzer spectra of 140 active galactic nuclei (AGN) detected in the hard X-rays (14–195 keV) by the Burst Alert Telescope on board Swift. This sample allows us to probe several orders of magnitude in black hole masses (106–109
M
⊙), Eddington ratios (10−3–1), X-ray luminosities (1042–1045 erg s−1), and X-ray column densities (1020–1024 cm−2). The AGN emission is expected to be the dominant source of ionizing photons with energies ≳50 eV, and therefore, high-ionization mid-infrared (MIR) emission lines such as [Ne v] 14.32, 24.32 μm and [O iv] 25.89 μm are predicted to be good proxies of AGN activity, and robust against obscuration effects. We find high detection rates (≳85%–90%) for the MIR coronal emission lines in our AGN sample. The luminosities of these lines are correlated with the 14–150 keV luminosity (with a typical scatter of σ ∼0.4–0.5 dex), strongly indicating that the MIR coronal line (CL) emission is driven by AGN activity. CLs are also tightly correlated to the bolometric luminosity (σ ∼0.2–0.3 dex), calculated from careful analysis of the spectral energy distribution. We find that the relationship between the CL strengths and L
14–150 keV is independent of black hole mass, AGN luminosity, and Eddington ratio, and mostly not affected by high X-ray column densities. This confirms that the MIR CLs can be used as unbiased tracers of the AGN power for X-ray luminosities in the 1042–1045 erg s−1 range.

We present spectroscopy of the ultra-faint Milky Way satellites Eridanus III (Eri III) and DELVE 1. We identify eight member stars in each satellite and place nonconstraining upper limits on their velocity and metallicity dispersions. The brightest star in each object is very metal poor, at [Fe/H] = −3.1 for Eri III and [Fe/H] = −2.8 for DELVE 1. Both of these stars exhibit large overabundances of carbon and very low abundances of the neutron-capture elements Ba and Sr, and we classify them as CEMP-no stars. Because their metallicities are well below those of the Milky Way globular cluster population, and because no CEMP-no stars have been identified in globular clusters, these chemical abundances could suggest that Eri III and DELVE 1 are dwarf galaxies. On the other hand, the two systems have half-light radii of 8 pc and 6 pc, respectively, which are more compact than any known ultra-faint dwarfs. We conclude that Eri III and DELVE 1 are either the smallest dwarf galaxies yet discovered, or they are representatives of a new class of star clusters that underwent chemical evolution distinct from that of ordinary globular clusters. In the latter scenario, such objects are likely the most primordial star clusters surviving today. These possibilities can be distinguished by future measurements of carbon and/or iron abundances for larger samples of stars or improved stellar kinematics for the two systems.

EK Draconis, a nearby young solar-type star (G1.5V, 50–120 Myr), is known as one of the best proxies for inferring the environmental conditions of the young Sun. The star frequently produces superflares, and Paper I presented the first evidence of an associated gigantic prominence eruption observed as a blueshifted Hα Balmer line emission. In this paper, we present the results of the dynamical modeling of the stellar eruption and examine its relationship to the surface starspots and large-scale magnetic fields observed concurrently with the event. By performing a 1D freefall dynamical model and a 1D hydrodynamic simulation of the flow along the expanding magnetic loop, we found that the prominence eruption likely occurred near the stellar limb (12

degrees relative to the line of sight, and the magnetic structures can expand into a coronal mass ejection. The observed prominence displayed a terminal velocity of ∼0 km s−1 prior to disappearance, complicating the interpretation of its dynamics in Paper I. The models in this paper suggest that prominence’s Hα intensity diminishes at around or before its expected maximum height, explaining the puzzling time evolution in observations. The Transiting Exoplanet Survey Satellite light curve modeling and (Zeeman) Doppler Imaging revealed large midlatitude spots with polarity inversion lines and one polar spot with dominant single polarity, all near the stellar limb during the eruption. This suggests that midlatitude spots could be the source of the gigantic prominence we reported in Paper I. These results provide valuable insights into the dynamic processes that likely influenced the environments of early Earth, Mars, Venus, and young exoplanets.
Applying the Velocity Gradient Technique in NGC 1333: Comparison with Dust Polarization Observations

Magnetic fields (B-fields) are ubiquitous in the interstellar medium (ISM), and they play an essential role in the formation of molecular clouds and subsequent star formation. However, B-fields in interstellar environments remain challenging to measure, and their properties typically need to be inferred from dust polarization observations over multiple physical scales. In this work, we seek to use a recently proposed approach called the velocity gradient technique (VGT) to study B-fields in star-forming regions and compare the results with dust polarization observations in different wavelengths. The VGT is based on the anisotropic properties of eddies in magnetized turbulence to derive B-field properties in the ISM. We investigate that this technique is synergistic with dust polarimetry when applied to a turbulent diffused medium for the purpose of measuring its magnetization. Specifically, we use the VGT on molecular line data toward the NGC 1333 star-forming region (12CO, 13CO, C18O, and N2H+), and we compare the derived B-field properties with those inferred from 214 and 850 μm dust polarization observations of the region using Stratospheric Observatory for Infrared Astronomy/High-Resolution Airborne Wide-band Camera Plus and James Clerk Maxwell Telescope/POL-2, respectively. We estimate both the inclination angle and the 3D Alfvénic Mach number M
A from the molecular line gradients. Crucially, testing this technique on gravitationally bound, dynamic, and turbulent regions, and comparing the results with those obtained from polarization observations at different wavelengths, such as the plane-of-sky field orientation, is an important test on the applicability of the VGT in various density regimes of the ISM. We in general do not find a close correlation between the velocity gradient inferred orientations and the dust inferred magnetic field orientations.
Dark Photon Dark Matter and Low-frequency Gravitational-wave Detection with Gaia-like Astrometry

Astrometric surveys offer us a method for searching for elusive cosmic signatures, such as ultralight dark photon dark matter and gravitational waves (GWs), by observing the temporal change of stars’ apparent locations. The detection capabilities of such surveys rapidly decrease at low frequencies, because the signals become hardly distinguishable from the background motion of stars. In this work, we find that the background motion can be well described by a linear model over time, based on which we propose a linear background subtraction scheme. Compared to the conventional quadratic subtraction, the advantage of linear subtraction emerges within the frequency range below 6 × 10−9 Hz. Taking dark photons with purely gravitational interactions, dark photons with additional U(1)
