Published: November 2024

Filipina telah menjadi negara yang aktif mengirim pekerja ke seluruh dunia sejak era 1970-an, terutama para pekerja tenaga ahli. Tingginya tingkat migrasi tenaga ahli di Filipina didorong oleh budaya masyarakat yang percaya bahwa bekerja di luar negeri dapat meningkatkan kualitas hidup mereka. Namun, fenomena ini telah menimbulkan masalah internal, yakni munculnya fenomena brain drain. Brain drain dipicu oleh faktor penarik dan faktor pendorong. Faktor-faktor tersebut dapat dianalisis lebih lanjut melalui keterkaitannya dengan wilayah asal, wilayah destinasi, hambatan yang mengintervensi, dan faktor personal. Penelitian ini bertujuan untuk menganalisis fenomena migrasi internasional tenaga ahli dan dampak brain drain di Filipina tahun 2015 hingga 2023 menggunakan push-pull factors. Penulis menggunakan pendekatan deskriptif kualitatif untuk mendeskripsikan fenomena yang terjadi. Metode pengumpulan data yang digunakan termasuk wawancara dan studi literatur. Hasil penelitian ini menggambarkan hubungan yang erat antara migrasi internasional di Filipina dan fenomena brain drain yang berdampak pada sektor-sektor penting seperti ekonomi, politik, dan sosial-budaya Filipina.

Analysis of International Expert Migration: A Case Study of Brain Drain in the Philippines in 2015-2023
Abstract: The Philippines has actively sent workers around the world since the 1970s, particularly highly skilled workers. The Philippines' high level of skilled migration has been driven by a culture in which people assume that working abroad will improve their standard of living. However, this trend ended up resulting in internal difficulties, including the rise of the brain drain phenomenon. Brain drain is caused by both pull and push causes. These elements can be examined further in relation to the place of origin, destination region, intervening obstacles, and personal factors. The purpose of this study is to examine the phenomenon of international highly skilled migration and the impact of brain drain in the Philippines between 2015 and 2023 utilizing push-pull factors. The author employs a qualitative descriptive approach to describe the phenomena that occur. Interviews and literature reviews were employed as data-gathering strategies. The findings of this study demonstrate the significant correlation between international migration in the Philippines and the brain drain issue, which has consequences for key areas such as the Philippine economy, politics, and sociocultural.

Do agroholdings cope better with the agency problem? Empirical evidence from corporate farms in Russia
Authors: Tleubayev Alisher , Syzdykov Yerzhan 
Published: November 2024

The agricultural industry in Russia demonstrated a notable growth since 2010. Russian policymakers strive to further increase agricultural production and set new targets for the industry for the years ahead. While agroholdings are regarded as one of the main driving forces behind the recent success in the agricultural sector, they are also believed to be the main locomotive that will move agriculture towards the set goals.
In spite of their growing importance, the literature on agroholdings is still relatively immature and fails to provide clear evidence of their financial efficiency as opposed to non-agroholding farms. The current study utilizes a manually sourced longitudinal dataset of 203 corporate farms in Russia and provides a new empirical evidence on the financial performance of agroholding farms through the prism of an agency problem.
Our findings reveal a significant positive relationship between agroholding membership and financial performance, as indicated by two accounting indicators – return on assets (ROA) and return on sales (ROS). We further observe that agroholdings face lower agency costs, which to a certain extent, explain their higher financial performance compared to stand-alone farms. The study offers empirical recommendations for policymakers and corporate executives in the Russian agricultural sector.

Published: November 2024

Mammograms, once mere X-ray images, are now powerful allies in the fight against breast cancer. Armed with sophisticated statistical image classification techniques, these images reveal hidden clues that can lead to early detection. Beneath the surface of a mammogram lies a complex tapestry of patterns, each one a potential marker of malignancy. By decoding these intricate patterns, algorithms can identify abnormalities that might otherwise go unnoticed. The Mammographic Image Analysis Society (MIAS) has been at the forefront of this revolution, creating a vast database of digital mammograms. From this treasure trove, we've selected 322 images to put our statistical prowess to the test. Using a powerful machine learning tool known as Support Vector Machine (SVM), we've classified these images into seven categories:

•	Calcifications (CALC): Tiny, hard deposits.
•	Circumscribed (CIRC) masses: Well-defined lumps.
•	Speculated (SPIC) masses: Lumps with spiky edges.
•	Ill-defined (MISC) masses: Irregular, indistinct lumps.
•	Architectural distortions (ARCH): Changes in the breast's structure.
•	Asymmetry(s) (ASYM): Differences between the two breasts.
•	Normal (NORM): Healthy breast tissue.

Our goal is to shed light on the intricate process of mammogram classification and share the insights gained from our analysis presented in the user-friendly language and the analysis is carried out using MATLAB.
SOCIAL MEDIA STRATEGIES FOR ORGAN DONATION IN MALAYSIA: A CONTENT ANALYSIS OF ‘DERMA ORGAN’ FACEBOOK PAGE
Authors: Teng Kai En , Maniam Pushpavalli 
Published: November 2024

Abstract: Organ donation, with its low donation rate and high demands, is undoubtedly one of Malaysia's most important health-related challenges. Despite the government's extensive efforts, little has changed in terms of swaying public opinion to pledge as an organ donor. There is ever-increasing number of people needing transplantation and the organs made available is definitely less. As numerous individuals require transplants, there are obviously fewer available organs to meet the demand. The study aims to contribute towards this issue, focusing on examining the social media strategies used by the government in transmitting the organ donation information as well as persuading Malaysians to pledge as an organ donor. The study intends to make a contribution to this issue by evaluating the social media tactics the government uses to disseminate information about organ donation and encourage Malaysians to sign up as donors. Using qualitative content analysis, information was gathered from the official ‘Derma Organ’ Facebook page. The data has been evaluated and associated to the engagement rates using cognitive, affective and conative message strategies. The analysis resulted with the majority of posts used a cognitive technique, while affective strategy appears to have a greater rate of engagement. To improve the public's desire to commit as an organ donor, more emphasis should be placed on valuing emotive strategy when creating social media content.

Published: November 2024

Abstract: Scams are systematically executed crimes. Criminal tactics are organized based on the targeted victims, timing, and technological advances. Various approaches have been implemented by authorities to educate and raise awareness among the public regarding the modus operandi and methods of self-protection against these crimes. Therefore, this study aims to identify the level of knowledge and behaviour on self protection against scam crimes among teenagers in Malaysia. A total of 482 teenagers aged 16 to 19 participated in this study. The survey instrument involved five constructs and 29 items formulated based on guidelines, campaigns, and promotional materials implemented by various authoritative agencies in Malaysia. Data were analyzed using descriptive analysis in the form of frequency, percentage, and cross tabs analysis. While the inference analysis used was the multiple regression analysis to analyze the influence of each variable toward respondents’ behaviour. The analysis results found that the scores of teenagers’ knowledge for two constructs were high (data information, data security), and three constructs were moderate (communication, digital content, problem-solving). Whereas the finding of multiple regression analysis indicated that all variables were significant in influencing respondents’ behaviour except for the digital content variable. Overall, this study proved that the protective actions taken by authorities against scam crimes were effective. However, these efforts need to be continued to ensure that these preventive elements can still be practiced in the future.

Antimicrobial Activities of Cucurbita moschata Leaves Water Extracts Against Selected Bacteria and Their Compound Determination
Authors: Alwi Afnani 
Published: November 2024

In Malaysia, high-value cash crops such as pumpkin (Cucurbita moschata) are cultivated, but their production generates significant agricultural waste. Discarded fruits, stems, and leaves are waste materials with multiple potential uses. Therefore, this study aimed to examine the antibacterial properties and determine the types of phytochemical components available in water extracts from pumpkin (C. moschata) leaves as an agricultural waste extract. Microwave-assisted extraction (MAE) is used to extract the plants' leaves due to its ease of use, quick extraction time, affordability, and increased yield. The leaves are obtained from Kampus Tembila, Universiti Sultan Zainal Abidin (UniSZA), Besut, Terengganu. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were run to visualise and determine the minimum concentration of pumpkin leave water extract that inhibits the six selected bacteria strains related to the gastrointestinal system of small ruminants which are Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae, Enterococcus faecalis, Salmonella enterica, and Acinetobacter baumannii. Thin Layer Chromatography (TLC) was used for the phytochemical screening, and reagents such as Vanillin, Anisaldehyde, Dragendorff's, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methanol solution were sprayed to identify the type of compound's presence in the aqueous extracts of both leaves. C. moschata leaves show inhibition activity against all microbes tested except B. subtilis, and the lowest IC50 inhibition was 8 mg/ml against A. baumannii and 20 mg/ml for E. faecalis, respectively. In the meantime, the aqueous extracts of C. moschata leaves contain natural compounds such as triterpenes, alkaloids, tannins and antioxidants, as indicated by coloured spots derived from the TLC visualization method.

Published: November 2024

The purpose of the study was to investigate whether identification with a women's group had helped women achieve economic empowerment. The study was underpinned by the social identity and economic empowerment theories and adopted a mixed methods approach. The quantitative data was collected using 360 questionnaires that were given to women while qualitative data was collected from 21 key informants and 20 focus groups. The quantitative data analysis involved descriptive statistics and Structural Equation Modeling using SMART PLS Version 4 while qualitative data was analysed using NVIVO software. The study findings supported the tenets of social identity theory. In this, the constructs of group identity, that is, group centrality, in-group affect and in-group ties did positively influence economic empowerment. However, the association between centrality and financial autonomy, centrality and economic security, in-group ties and decision-making were not supported. It is recommended that Promoters of these groups promote transparent and fair leadership, group leaders adhere to principles of transparency, fairness, and inclusivity. Any form of perceived favouritism be managed in time to foster trust and positive emotional attachment within the group

Aim: The study aims to highlight methodological issues in estimating exposure to domestic violence (DV). It also aims to provide information on the reasons for underreporting DV cases.
Methodology: The researchers rely on data available in the Unified Criminal Statistics of the Investigating Authority and the Prosecutor's Office to describe the number of victims of domestic violence. They also present some findings of a representative survey.
Findings: Latency is high in cases of domestic violence. The difficulty in accurately estimating latency is that different data collection methods and different research questions reveal different levels of exposure. Police have a crucial role in the disclosure of DV. The main reason for under-reporting is the emotional state of the victims (including embarrassment and shame) who sometimes would like to keep the abuse a secret.
Value: According to the study, different data collections and methodologies may give different estimations about the number of victims of DV. Information on the reasons for non-reporting can increase the efficiency of professionals, aiming at the prevention and response to domestic violence. In light of the results, especially the high proportion of male victims, further research questions can be identified.
Could the Recent Rebrightening of the GW170817A Afterglow Be Caused by a Counterjet?
Authors: Dastidar Ranadeep G. , Duffell Paul C. 
Published: November 2024

Abstract
GRB 170817A (also GW170817) became the first binary neutron star merger event detected via gravitational waves and electromagnetic signals. Over the next 4 yr, various multiband observations have led to reimaging of the various short gamma-ray burst and interstellar medium interaction models. While these models successfully explain the observed afterglow until ∼900 days, a rebrightening or excess flux was observed in the 1 keV X-ray band after ∼1000 days. In this study, we reevaluate the jet parameters using new observations (until ∼1234 days) with a boosted fireball jet model. We study the observable effects of the counterjet for GRB 170817A, using our new afterglow code, firefly. Our results show that it is indeed possible for the observed excess to coincide with the emissions from a counterjet (∼800 days). We also computed an empirical scaling law between the jet and counterjet peak emission timescales and the observer angle. The firefly code can also track the simulated object through the observer’s sky and numerically model the apparent motion. The calculated apparent motion (≈2.6c) does not match the observed apparent motion (5.2c−7.5c). Hence we conclude that the excess flux of GRB 170817A may not be associated with a counterjet; however, it is not enough to reject this hypothesis from the traditional counterjet visibility timescale, which predicts ≥5000 days. The apparent motion, combined with the multiband lightcurves, is needed to break the degeneracy between the geometrical parameters and the microphysical parameters of the afterglow.

Abstract
We present 850 μm thermal dust polarization observations with a resolution of 14.″4 (∼0.13 pc) toward an infrared dark cloud G16.96+0.27 using James Clerk Maxwell Telescope/POL-2. The average magnetic field orientation, which roughly agrees with the larger-scale magnetic field orientation traced by the Planck 353 GHz data, is approximately perpendicular to the filament structure. The estimated plane-of-sky magnetic field strength is ∼96 μG and ∼60 μG using two variants of the Davis–Chandrasekhar–Fermi methods. We calculate the virial and magnetic critical parameters to evaluate the relative importance of gravity, the magnetic field, and turbulence. The magnetic field and turbulence are both weaker than gravity, but magnetic fields and turbulence together are equal to gravity, suggesting that G16.96+0.27 is in a quasi-equilibrium state. The alignment between the magnetic field and cloud is found to have a trend moving away from perpendicularity in the dense regions, which may serve as a tracer of potential fragmentation in such quiescent filaments.
Double-edged Sword: The Influence of Tidal Interaction on Stellar Activity in Binaries

Published: November 2024

Abstract
Using the LAMOST DR7 low-resolution spectra, we carried out a systematic study of stellar chromospheric activity in both single and binary stars. We constructed a binary sample and a single-star sample, mainly using the binary belt and the main sequence in the Hertzsprung–Russell diagram, respectively. By comparing the S indices between single and binary stars within each color bin, we found for K-type stars, binaries exhibit enhanced activity compared to single stars, which could be attributed to the increase in spin rate caused by tidal synchronization or to the interactions of magnetic fields. Both single stars and binaries fall on a common sequence in the activity-period relation, indicating that the chromospheric activities of binaries are dominated by the more active components. More intriguingly, in some color ranges, a slight decline of the S index for smaller orbital periods was observed for binary stars. Although the possibility of sample selection effects cannot be excluded, this may mark the first example of supersaturation (i.e., caused by reduced active regions) being detected in chromospheric activity, or provide evidence of the suppressing effect on the magnetic dynamo and stellar activities by strong tidal interaction in very close binaries. Our study suggests that tidal interaction acts as a double-edged sword in relation to stellar activities.
Agrippa, il porto e il teatro di Ostia
Authors: Pensabene Patrizio 
Published: November 2024

Il presente lavoro tratta del ruolo del porto di Ostia nell’approvvigionamento anche dei marmi, indispensabili per realizzare i programmi monumentali di Augusto a Roma. Solo nel foro di Augusto si impiegarono almeno 289 colonne monolitiche e semicolonne addossate a pilastri in pavonazzetto, giallo antico, portasanta, africano, cipollino. Tali varietà formarono la classica pentacromia augustea che venne trasmessa a tutto il periodo imperiale successivo. In tale impresa di marmorizzazione dell’Urbe Augusto si avvalse della collaborazione di Agrippa. Questi aveva stabilito rapporti con la classe dirigente Ostiense, in particolare con Gamala e Cartilio Poplicola, in occasione della guerra navale contro Sesto Pompeo. Agrippa fu forse patrono della città e in ogni caso vi promosse il teatro in una zona demaniale ancora libera presso le sponde meridionali e non lontana dalla foce del Tevere. La costruzione dovette essere terminata nel 18 o il 17 a.C. e la conferma di questa datazionene viene dallo studio degli elementi architettonici superstiti di questa fase.

Published: November 2024

Trois étudiantes et étudiants en Master Histoire publique à Nantes Université se sont prêtés au jeu de rassembler l’histoire publique et l’histoire des techniques à travers leur projet annuel de Master 1. Ils ont réalisé un documentaire : La corderie Plantive, de l’atelier à l’écomusée. Ce dernier retrace l’histoire de la corderie depuis le début du XXe siècle à sa transformation en écomusée en 2019. Cette réalisation est le fruit d’un sérieux travail scientifique de recherches, mais aussi d’un travail de création de A à Z d’un film-documentaire. Cet article retrace tant bien l’histoire de cette corderie machecoulaise, en traitant par ce biais la technicité propre au métier de cordier ; que la possibilité pour l’histoire publique de se mettre au service de l’histoire des techniques, pour pouvoir lui donner un autre souffle.
