The Evolution of Human Rights and the Legal Framework for Genocide Prevention: From the Holocaust to Rwanda
Authors: Şenyurt Sümer Esin
Published: August 2024

Human rights are inherent entitlements that individuals possess by virtue of their humanity. Throughout history, various atrocities and inhumane acts have occurred, with the First and Second World Wars exemplifying the most severe massacres. The crime of genocide was first legally addressed in the United Nations Genocide Convention within the framework of International Law. Genocide is considered one of the gravest violations of human rights under international humanitarian law. The Holocaust during the Second World War, perpetrated by the Nazis, and the genocide in Rwanda are prominent examples that elicited significant international backlash, prompting legal sanctions against such heinous acts. This article aims to elucidate the concept of genocide and its historical evolution, examining the rulings of international criminal courts on genocide. By analyzing the Holocaust and the Rwanda genocide, the study seeks to provide a comprehensive understanding of genocide as a crime against humanity influenced by international issues, geopolitical dynamics, and colonialism.
Comparative Analysis of the Content of Online Magazines of the Islamic State of Iraq and Syria (ISIS) in Different Languages: Dabiq, Rumiyah, and Konstantiniyye
Authors: Tulga Ahmet Yiğitalp
Published: August 2024

The Islamic State of Iraq and Syria (ISIS) effectively uses online magazines for propaganda, leveraging advanced internet technologies to disseminate its message in multiple languages. This study investigates ISIS's use of online magazines to promote its self-proclaimed jihad and attract recruits globally. While existing research examines ISIS's multilingual magazines, few studies comprehensively compare them across languages. This study conducts a text analysis of Dabiq and Rumiyah in English and Konstantiniyye in Turkish. The findings reveal that all magazines construct distinct “us” versus “them” identities, focusing on religion and justification. Konstantiniyye, targeting Turkish Muslims, emphasizes stronger religious themes compared to Dabiq and Rumiyah. Overall, these magazines discuss legal systems, jihad, state structure, and social order, advocating for Muslim unification under a single “caliphate.” This analysis sheds light on ISIS's diverse propaganda strategies tailored to different linguistic contexts.
The Perils of Global Governance: Why has the European Union Failed to Address Corruption in Kosovo?
Authors: Persaud Paul
Published: August 2024

Since the Kosovo War ended on June 10, 1999, the European Union (EU) has allocated vast influxes of official development assistance (ODA) to Kosovo, including humanitarian aid, technical assistance and financial grants. In large, this support has sought to facilitate accountable, democratic governance that fosters ‘uncorrupt’ institutions within the country. Although the EU has made considerable advances in this pursuit, Kosovo’s public institutions remain riddled with corruption, notably access payments, which impede the development of transparent governing bodies. Accordingly, this paper conducts a critical analysis to assess why the European Union has been unable to address widespread corruption in Kosovo. It contends that during the international post-conflict reconstruction of Kosovo, the EU provided ODA to local political elites who used such resources to establish clientelist networks that undermine accountable, democratic governance. This advent created ‘path dependency’, making institutional reform difficult thereafter. Second, ODA programs from the EU have imposed market-oriented reforms that have directly and indirectly nurtured clientelism when implemented.

Published: August 2024

Backgrounds/Aims: Despite advances in antiviral therapy for hepatitis C virus (HCV) infection, hepatocellular carcinoma (HCC) still develops even after sustained viral response (SVR) in patients with advanced liver fibrosis or cirrhosis. This meta-analysis investigated the predictive performance of vibration-controlled transient elastography (VCTE) and fibrosis 4-index (FIB-4) for the development of HCC after SVR.Methods: We searched PubMed, MEDLINE, EMBASE, and the Cochrane Library for studies examining the predictive performance of these tests in adult patients with HCV. Two authors independently screened the studies’ methodological quality and extracted data. Pooled estimates of sensitivity, specificity, and area under the curve (AUC) were calculated for HCC development using random-effects bivariate logit normal and linear-mixed effect models.Results: We included 27 studies (169,911 patients). Meta-analysis of HCC after SVR was possible in nine VCTE and 15 FIB-4 studies. Regarding the prediction of HCC development after SVR, the pooled AUCs of pre-treatment VCTE >9.2–13 kPa and FIB-4 >3.25 were 0.79 and 0.73, respectively. VCTE >8.4–11 kPa and FIB-4 >3.25 measured after SVR maintained good predictive performance, albeit slightly reduced (pooled AUCs: 0.77 and 0.70, respectively). The identified optimal cut-off value for HCC development after SVR was 12.6 kPa for pre-treatment VCTE. That of VCTE measured after the SVR was 11.2 kPa.Conclusions: VCTE and FIB-4 showed acceptable predictive performance for HCC development in patients with HCV who achieved SVR, underscoring their utility in clinical practice for guiding surveillance strategies. Future studies are needed to validate these findings prospectively and validate their clinical impact.

Candombe’s Costume as a Key Element to Discover Uruguayan History
Authors: Eugenia Vídal María
Published: August 2024

Performances that become rituals, which are preserved through decades, even centuries, are formed by history. Every aspect that composes them speaks about the community represented, the intended audience and the surroundings. Costume is the most visible element a performer has to spread a message in the most democratic way possible. The capital city of a small South American country — Montevideo, Uruguay — presents Candombe, an interesting carnival celebration first performed by enslaved Afro-Uruguayans which has become a popular event that now represents a significant part of the country’s culture. This article aims to understand the origins of the costume for this particular ritual and why the design is preserved today in contemporary celebrations. The topics discussed are colonialism, memory, tradition and multiculturalism. In addition, the concept of agency in regard to the costume is addressed with concrete examples.
Ambiguity as a Sign of Degeneration?: Japanese Kimonos in Art, Fashion and Criticism of fin de siècle Britain
Authors: Yamaguchi Arisa
Published: August 2024

Several important studies of Japonisme in fashion have considered the design and cultural influence of Japanese kimonos on the art and fashionable world. However, there is much more to discuss when it comes to how the kimono trend as a phenomenon actually correlated with the beliefs, thoughts and spirit of the time. Using Max Nordau’s Degeneration as a critical starting point, this article intends to explore what the adoption and the representation of kimonos could mean concerning the Victorian idea of progress and degeneration of human bodies by analysing the radical use of kimonos in the artworks by a Decadent artist, Aubrey Beardsley, and the adoption of kimono-related gowns among mainstream fashion. While the artistic representations of Japanese kimonos cover up the wearers’ bodies to stress ambiguity, ‘kimonos’ that were widely accepted by upper- and upper-middle-class women were greatly modified to recreate the hourglass silhouette that most Victorians were accustomed to seeing. This article shows the power of kimonos to allow Victorian bodies to escape, transform and hide from the conventional norms of the period, which proposes an entirely new direction of studies of Japonisme in fashion.
Wars and Capital – after Deleuze and Guattari and Foucault
Authors: Alliez Éric
Published: August 2024

Territory and population, migration, division of territories and their globalised populations… Re-presenting in this paper Wars and Capital (written with Maurizio Lazzarato, first published 2016), we’ll argue that Deleuze and Guattari’s view on this complex of relations must be reconstructed from their understanding of war’s constitutive relationship with capitalism by taking up the confrontation with Clausewitz to reverse the famous formula that war is/is only the continuation of politics by other means. Except that, as with Foucault, albeit differently, it is not so much a question of reversal but an interweaving of war in politics and politics in war that adopts the movements of capitalism in the twentieth century’s world economy. Politics is not, as in Clausewitz, the politics of the state but the war machine of the financialised economy interwoven in the multiplicity of wars that move and hold together the war of destruction in action with wars of class, race and sex under the auspices of a ‘war amongst the people’ that provide the fractal environment of all the others when war and peace become indistinguishable in a neoliberalism of combat. A transversal and global civil war that is also a war of subjectivity fractures all territories in the North(s) and South(s) since internal and external colonisations are no longer distributed only geographically. As proof, if needed, more than forty years after the publication of A Thousand Plateaus – it is not enough to state that micropolitics has to pass into macropolitics to transform it: both micro- and macropolitics have to be part of the multiplicity of wars that take place, without which both micro- and macropolitics collapse in the ‘becoming-minor’ of the ‘missing people’.
A fatal complication of tracheostomy cannula exchange: Bilateral pneumothorax, pneumomediastinum, and subcutaneous emphysema
Authors: Çatal Fatih
Published: August 2024

Introduction: Although tracheostomy opening or replacement is generally a safe procedure, it carries varying risks of complications. Serious complications include false lumen formation between tissues surrounding the trachea, tracheal posterior wall damage, bleeding, pneumomediastinum, pneumothorax, and death. The incidence of these complications increases especially in patients who are obese, have a short neck or anatomical deformity.
Case Report: A 24-year-old male patient was brought to the emergency department with respiratory distress. His family stated that his complaints started four days ago after the change of the tracheostomy cannula in a hospital. Computed tomography of the neck and chest revealed subcutaneous emphysema in the neck and anterior chest, free air between deep tissues in the neck, pneumomediastinum and bilateral pneumothorax. Supportive oxygen therapy was started and the patient was consulted for thoracic surgery. After tube thoracostomy of the right hemithorax, intensive care unit hospitalization was performed. The patient died on the 25th day of intensive care unit hospitalization due to type 2 respiratory failure.
Conclusion: In patients with tracheostomy presenting to the emergency department with dyspnea, cannula-related causes should also be considered in the differential diagnosis.

PERAN MIKROBIOMA KULIT PADA AKNE
Authors: Sari Ninda , Adriman Zikri , Pradistha Aldilla
Published: August 2024

Kulit adalah permukaan terluar tubuh, yang berfungsi untuk membentuk barier pelindung antara tubuh dan lingkungan eksternal. Kulit terdiri dari populasi mikroorganisme yang berbeda yang berada di lapisan epidermis dan dermis. Mikrobioma kulit berpartisipasi secara fisik, kimia, mikroba dan jalur imunologi bawaan serta adaptif dalam perannya sebagai barier kulit. Hilangnya keragaman mikrobioma kulit, serta perubahan komposisi alami, mendorong perkembangan penyakit inflamasi di kulit, seperti akne. Akne vulgaris adalah peradangan folikel sebaseus manusia yang paling sering. Beberapa mekanisme telah diusulkan dimana Cutibacterium acnes memperberat akne, termasuk aktivitas kelenjar sebaseus, pembentukan komedo, dan respon inflamasi pejamu. Meskipun peran C.acnes dalam patofisiologi akne tidak sepenuhnya dipahami, hilangnya keseimbangan antara filotipe C.acnes tampaknya berperan dalam memicu akne. Tidak ada perbedaan yang signifikan dari distribusi strain C.acnes pada akne ringan dan berat. Staphylococcus epidermidis dapat mengontrol proliferasi C.acnes melalui fermentasi gliserol menjadi asam lemak rantai pendek dan melepaskan asam suksinat. Mallasezia juga jenis fungal yang hidup berdampingan dengan C.acnes dan dianggap potensial untuk menginduksi akne refrakter. Interaksi mikroorganisme di usus dan sistem kekebalan tubuh pejamu penting untuk menjaga homeostasis kulit melalui aksis usus-kulit.

Authors: Setio Wati Sri Karunia , Jusuf Nelva Karmila
Published: August 2024

Filler adalah produk yang disuntikkan melalui jarum tajam atau kanula ke dalam kulit pada kedalaman yang berbeda, untuk memberikan volume pada dermis dan lemak subkutan. Filler banyak digunakan untuk indikasi estetika, karena dapat memperbaiki penampilan dengan menghaluskan atau menyamarkan garis-garis, tanda penuaan, dan kerutan di wajah dan tubuh. Selain itu, terdapat partikel kecil asam hialuronat (HA) yang dikenal sebagai skinbooster, yang merupakan metode baru dalam peremajaan kulit. Penyuntikan skinbooster berbeda dari filler, dimana penyuntikan dilakukan secara serial micropuncture intradermal dengan sejumlah kecil produk yang tidak memiliki fungsi untuk menciptakan volume (efek "volumizing") tetapi untuk melembabkan, mengencangkan dan menutrisi kulit secara mendalam dan tahan lama untuk melawan efek penuaan kulit. Tindakan filler dan skinbooster ini dapat dilakukan sesuai indikasi, dengan tetap memperhatikan kontraindikasinya. Selain itu juga harus dilakukan sesuai dengan prosedur yang direkomendasikan, untuk mengurangi kemungkinan terjadinya komplikasi.

Pendahuluan: Pioderma gangrenosum (PG) adalah dermatosis inflamasi neutrofilik langka yang ditandai dengan gambaran klasik berupa ulkus kulit yang khas, berkembang dengan cepat dan menyakitkan. Lebih dari 50% lesi berkembang karena fenomena patergi, yaitu timbulnya lesi PG di lokasi kulit yang mengalami trauma. Sebanyak 50-75% kasus memiliki penyakit sistemik yang mendasari, misalnya keganasan organ padat. Diagnosis PG biasanya sulit ditegakkan secara dini. Kasus: Wanita 68 tahun dengan riwayat kanker payudara menunjukkan lesi ulseratif progresif di area perut hingga punggung, yang muncul setelah infeksi herpes zoster (HZ). Biopsi dilakukan untuk menyingkirkan kemungkinan suatu keganasan, infeksi, atau vaskulitis, dan mendukung diagnosis PG. Terapi kortikosteroid sistemik dosis tinggi menunjukkan respons yang baik dalam 1 minggu. Diskusi: PG ulseratif adalah varian yang paling sering ditemui, termasuk pada PG yang terkait paraneoplastik. Terdapat dua kriteria diagnostik yang dapat membantu penegakkan diagnosis PG, yaitu kriteria diagnostik PG ulseratif dan sistem penilaian PARACELSUS. Kesimpulan: PG perlu menjadi pertimbangan diagnosis pada kasus ulseratif dengan kemungkinan adanya fenomena patergi dan penyakit sistemik yang mendasari. Pemeriksaan histopatologis perlu dilakukan untuk menyingkirkan diagnosis banding dan pengobatan dengan agen imunosupresif dianjurkan untuk PG.

Published: August 2024

Introduction

Recognizing and extracting key information from textual data plays an important role in intelligent systems by maintaining up-to-date knowledge, reinforcing informed decision-making, question-answering, and more. It is especially apparent in the food domain, where critical information guides the decisions of nutritionists and clinicians. The information extraction process involves two natural language processing tasks named entity recognition—NER and named entity linking—NEL. With the emergence of large language models (LLMs), especially ChatGPT, many areas began incorporating its knowledge to reduce workloads or simplify tasks. In the field of food, however, we noticed an opportunity to involve ChatGPT in NER and NEL.

Methods

To assess ChatGPT's capabilities, we have evaluated its two versions, ChatGPT-3.5 and ChatGPT-4, focusing on their performance across both NER and NEL tasks, emphasizing food-related data. To benchmark our results in the food domain, we also investigated its capabilities in a more broadly investigated biomedical domain. By evaluating its zero-shot capabilities, we were able to ascertain the strengths and weaknesses of the two versions of ChatGPT.

Results

Despite being able to show promising results in NER compared to other models. When tasked with linking entities to their identifiers from semantic models ChatGPT's effectiveness falls drastically.

Discussion

While the integration of ChatGPT holds potential across various fields, it is crucial to approach its use with caution, particularly in relying on its responses for critical decisions in food and bio-medicine.
Evolutionary optimization for risk-aware heterogeneous multi-agent path planning in uncertain environments
Authors: Rekabi Bana Fatemeh , Krajník Tomáš , Arvin Farshad
Published: August 2024

Cooperative multi-agent systems make it possible to employ miniature robots in order to perform different experiments for data collection in wide open areas to physical interactions with test subjects in confined environments such as a hive. This paper proposes a new multi-agent path-planning approach to determine a set of trajectories where the agents do not collide with each other or any obstacle. The proposed algorithm leverages a risk-aware probabilistic roadmap algorithm to generate a map, employs node classification to delineate exploration regions, and incorporates a customized genetic framework to address the combinatorial optimization, with the ultimate goal of computing safe trajectories for the team. Furthermore, the proposed planning algorithm makes the agents explore all subdomains in the workspace together as a formation to allow the team to perform different tasks or collect multiple datasets for reliable localization or hazard detection. The objective function for minimization includes two major parts, the traveling distance of all the agents in the entire mission and the probability of collisions between the agents or agents with obstacles. A sampling method is used to determine the objective function considering the agents’ dynamic behavior influenced by environmental disturbances and uncertainties. The algorithm’s performance is evaluated for different group sizes by using a simulation environment, and two different benchmark scenarios are introduced to compare the exploration behavior. The proposed optimization method establishes stable and convergent properties regardless of the group size.

Aim

This study aimed to evaluate the maternal and infant oral health benefits from mothers receiving prenatal total oral rehabilitation (PTOR) before childbirth.

Methods

Building upon our previous investigation, in which 15 expectant mothers received PTOR before their third trimester, achieving a state of oral health free from disease prior to delivery, we conducted a follow-up study to monitor these mothers and their newborns until they reached 2 years of age. We assessed the impact of PTOR on maternal and infant oral health, the utilization of dental care during the postpartum/early-life period, and the carriage of oral cariogenic microorganisms among mothers and their infants. Control groups consisting of 11 children and 17 mothers who did not undergo PTOR were included for comparative analysis.

Results

PTOR demonstrated a sustained improvement in maternal oral health outcomes by the end of 2 years postpartum, evidenced by a reduction in the Plaque Index and decayed surfaces compared with the control group (p < 0.05). PTOR was also associated with increased perinatal oral health literacy compared with the baseline of the mothers themselves (p < 0.05). In addition, PTOR led to a notable increase in maternal dental care utilization, rising from 26.7% before PTOR to 80% at 1 year postpartum and 70% at 2 years postpartum. Intriguingly, 40% of infants in the PTOR group had their first dental visit before reaching 1 year of age, in contrast to national data from the USA indicating a rate of less than 1%. Furthermore, a decrease in plaque Streptococcus mutans was observed in PTOR mothers 2 years postpartum, compared with both their baseline carriage and that of the control group (p < 0.05). Infants in the PTOR group also had a lower incidence of early childhood caries, with 18% in the PTOR group vs. 27% in the control group, although this difference was not statistically significant due to the small sample size.

Conclusions

PTOR is associated with sustained oral health benefits and improves dental care utilization by mothers and their infants. Large-scale clinical trials are warranted to validate these study findings.

Published: August 2024

An accurate gravity field model of Deimos can provide constraints for its internal structure modeling, and offer evidence for explaining scientific issues such as the origin of Mars and its moons, and the evolution of the Solar System. The Japanese Martian Moon Exploration (MMX) mission will be launched in the coming years, with a plan to reach Martian orbit after 1 year. However, there is a lack of executed missions targeting Deimos and research on high-precision gravity field of Deimos at this stage. In this study, a 20th-degree gravity field model of Deimos was constructed by scaling the gravity field coefficients of Phobos and combining them with an existing low-degree gravity field model of Deimos. Using simulated ground tracking data generated by three stations of the Chinese Deep Space Network, we simulate precise tracking of a spacecraft in both flyby and orbiting scenarios around Deimos, and the gravity field coefficients of Deimos have been concurrently computed. Comparative experiments have been conducted to explore factors affecting the solution, indicating that the spacecraft’s orbital altitude, the noise level of observation data, and the ephemeris error of Deimos have a significant impact on the solution results. The results of this study can provide references for planning and implementation of missions targeting Martian moons.

The internal losses in the tip clearance region strongly influence the compressor performance and its operational range. Previous research proved that passive wall treatments with circumferential grooves in axial compressors effectively increase the compressor stall margin. The vortex generated inside the circumferential grooves creates a resistance to the flow that leaks into the tip clearance region of the compressor. However, most works found in the literature on circumferential grooves in axial compressors deal only with high-performance single-stage axial compressors. Therefore, there is a need to investigate and analyze the behavior of circumferential grooves in a multi-stage environment. In the present work, a passive wall treatment with circumferential grooves was implemented in a multi-stage axial compressor. Different configurations of circumferential grooves were created at the casing of the first and second rotor rows used in a four-stage axial flow compressor. Numerical simulations were performed to evaluate the influence of the circumferential grooves on the performance of a multi-stage axial compressor. The results obtained after the simulations for the different circumferential groove configurations were compared with the results obtained for the compressor without casing treatment (smooth wall) for different rotational speeds. Furthermore, the complete compressor map characteristics were simulated for the different casing treatment configurations, and the results were compared with the compressor characteristics of the smooth wall case. The passive wall treatment with circumferential grooves produced changes in the multi-stage axial compressor flow field, especially in the tip clearance region, improving the compressor stability mainly for part load speeds.

Published: August 2024

Monitoring the evolution of pasture availability and quality throughout the growing season is the basis of grazing management in extensive Mediterranean livestock systems. Remote sensing (RS) is an innovative tool that, among many other applications, is being developed for detailed spatial and temporal pasture quality assessment. The aim of the present study is to evaluate the potential of satellite images (Sentinel-2) to assess indicators of pasture quality (pasture moisture content, PMC, crude protein, CP and neutral detergent fiber, NDF) using the normalized difference vegetation index (NDVI). Field measurements were conducted over three years at eight representative fields of the biodiversity and variability of dryland pastures in Portugal. A total of 656 georeferenced pasture samples were collected and processed in the laboratory. The results show a significant correlation between pasture quality parameters (PMC, CP and NDF) obtained in standard laboratory methods and NDVI satellite-derived data (R2 of 0.72, 0.75, and 0.50, respectively). The promising findings obtained in this large-scale validation study (three years and eight fields) encourage further research (i) to test and develop other vegetation indexes for monitoring pasture nutritive value; (ii) to extend this research to pastures of the other Mediterranean countries, building large and representative datasets and developing more robust and accurate monitoring models based on freely available Sentinel-2 images; (iii) to implement an extension program for agricultural managers to popularize the use of these technological tools as the basis of grazing and pasture management.
Impact of Application Rate and Spray Nozzle on Droplet Distribution on Watermelon Crops Using an Unmanned Aerial Vehicle
Authors: Ribeiro Luis Felipe Oliveira , Vitória Edney Leandro da
Published: August 2024

Watermelon is one of the most commonly grown vegetable crops worldwide due to the economic and nutritional importance of its fruits. The yield and quality of watermelon fruits are affected by constant attacks from pests, diseases, and weeds throughout all phenological stages of the crop. Labor shortages and unevenness of pesticide applications using backpack and tractor sprayers are significant challenges. The objective of this study was to evaluate the effect of different spray nozzles (XR110015 and MGA60015) and application rates (8, 12, and 16 L ha−1) on droplet distribution on different targets in watermelon plants using an unmanned aerial vehicle. Water-sensitive papers were used as targets to analyze the droplet coverage, deposition, density, and volume median diameter. Data were collected from targets placed on the leaf adaxial and abaxial sides, fruit, apical bud, and stem of each plant. The mean droplet coverage and density increased as the application rate was increased, with no significant interaction between the factors or statistical difference between spray nozzles, except for the leaf abaxial side. No significant differences were found for the variables analyzed at application rates of 12 and 16 L ha−1, whereas significant differences were observed at 8 L ha−1. The use of unmanned aerial vehicles in watermelon crops is efficient; however, further studies should be conducted to evaluate their effectiveness in pest control and compare them with other application methods.
