Abstract. The satellite radar altimetry record of sea level has now surpassed 30 years in length. These observations have greatly improved our knowledge of the open ocean and are now an essential component of many operational marine systems and climate studies. But use of altimetry close to the coast remains a challenge from both a technical and scientific point of view. Here, we take advantage of the recent availability of many new algorithms developed for altimetry sea level computation to analyze the sources of uncertainties of this procedure when approaching the coast. To achieve this objective, we did a round robin analysis of radar altimetry data, testing a total of 21 solutions for waveform retracking, correcting sea surface heights and finally deriving sea level variations. Uncertainties associated with each of the components used to calculate the altimeter sea surface heights are estimated by measuring the dispersion of sea level values obtained using the various algorithms considered in the round robin for this component. We intercompare these uncertainty estimates and analyze how they evolve when we go from the open ocean to the coast. At regional scale, complementary analyses are performed through comparisons to independent tide gauge observations. The results show that tidal corrections and mean sea surface can be significant contributors to sea level data uncertainties in many coastal regions. However, improving quality and robustness of the retracking algorithm used to derive both the range and the sea state bias correction, is today the main factor to bring accurate altimetry sea level data closer to the shore than ever before.
Surface CO2 Gradients Challenge Conventional CO2 Emission Quantification in Lentic Water Bodies under Calm Conditions
Authors: Aurich Patrick , Spank Uwe , Koschorreck Matthias
Published: August 2024

Abstract. Lakes are hotspots of inland carbon cycling and are important sources of greenhouse gases (GHGs), such as carbon dioxide (CO2). The significant role of CO2 in global carbon cycle makes quantifying its emission from various ecosystems, including lakes and reservoirs, important for developing strategies to mitigate climate change. The thin boundary layer method is a common approach to calculate CO2 fluxes from CO2 measurements in both the water and the air, and wind speed. However, one assumption for the TBL method is a homogeneous CO2 concentration between the measurement depth and the water surface, where gas exchange takes place. This assumption might not be true under calm conditions, when microstratification below the surface slows vertical exchange of gases. We used a floating outdoor laboratory to monitor CO2 concentrations in 5 cm and 25 cm depth, CO2 concentration in the air, wind speed, and water temperature profiles for one week in Bautzen Reservoir, Germany. While we found homogeneous CO2 concentrations in the two depths during wind speeds above 3 m s-1, there was a vertical gradient observed during wind still nights. The concentrations observed temporally ranged from undersaturation to supersaturation in 25 cm and 5 cm, respectively. Fluxes calculated from the measured concentrations therefore would change from negative to positive, depending on the measurement depth. Simultaneous Eddy Covariance measurements showed that even the measurements close to the surface underestimated the actual CO2 concentration. Oxygen measurements support our hypothesis that respirational processes at the water surface cause a temporal CO2 concentration gradient from the surface to the underlying water. Until now, the depth of CO2 measurements has not been questioned, as long as measurements were done in the upper mixed layer and close to the surface. Our results provide evidence that representative measurements of CO2 in the water strongly depend on depth and time of measurements.

Published: August 2024

Abstract. Active rock glaciers and landslides are critical indicators of permafrost dynamics in high mountain environments, reflecting the thermal state of permafrost and responding sensitively to climate change. Traditional monitoring methods, such as Global Navigation Satellite System (GNSS) measurements and permanent installations, face challenges in measuring the rapid movements of these landforms due to environmental constraints and limited spatial coverage. Remote sensing techniques offer improved spatial resolution but often lack the necessary temporal resolution to capture sub-seasonal variations. In this study, we introduce a novel approach utilising monoscopic time-lapse imagery and Artificial Intelligence (AI) for high-temporal-resolution velocity estimation, applied to two subsets of time-lapse datasets capturing a fast-moving landslide and rock glacier at the Grabengufer site (Swiss Alps). Specifically, we employed the Persistent Independent Particle tracking (PIPs++) model for tracking and the AI-based LightGlue matching algorithm to transfer 2D image data into 3D object space and further into 4D velocity data. This methodology was validated against GNSS surveys, demonstrating its capability to provide spatially and temporally detailed velocity information. Our findings highlight the potential of image-driven methodologies to enhance the understanding of dynamic landform processes, revealing spatio-temporal patterns previously unattainable with conventional monitoring techniques. By leveraging existing time-lapse data, our method offers a cost-effective solution for monitoring various geohazards, from rock glaciers to landslides, with implications for enhancing alpine safety and informing climate change impacts on permafrost dynamics. This study marks the pioneering application of AI-based methodologies in environmental monitoring using time-lapse image data, promising advancements in both research and practical applications within geomorphic studies.
RCEMIP-II: mock-Walker simulations as phase II of the radiative–convective equilibrium model intercomparison project
Authors: Wing Allison A. , Silvers Levi G. , Reed Kevin A.
Published: August 2024

Abstract. The radiative–convective equilibrium (RCE) model intercomparison project (RCEMIP) leveraged the simplicity of RCE to focus attention on moist convective processes and their interactions with radiation and circulation across a wide range of model types including cloud-resolving models (CRMs), general circulation models (GCMs), single-column models, global cloud-resolving models, and large-eddy simulations. While several robust results emerged across the spectrum of models that participated in the first phase of RCEMIP (RCEMIP-I), two points that stand out are (1) the strikingly large diversity in simulated climate states and (2) the strong imprint of convective self-aggregation on the climate state. However, the lack of consensus in the structure of self-aggregation and its response to warming is a barrier to understanding. Gaining a deeper understanding of convective aggregation and tropical climate will require reducing the degrees of freedom with which convection can vary. Therefore, we propose phase II of RCEMIP (RCEMIP-II) that utilizes a prescribed sinusoidal sea surface temperature (SST) pattern to provide a constraint on the structure of convection and move one critical step up the model hierarchy. This so-called “mock-Walker” configuration generates features that resemble observed tropical circulations. The specification of the mock-Walker protocol for RCEMIP-II is described, along with example results from one CRM and one GCM. RCEMIP-II will consist of five required simulations: three simulations with the same three mean SSTs as in RCEMIP-I but with an SST gradient and two additional simulations at one of the mean SSTs with different values of the SST gradients. We also test the sensitivity to the imposed SST gradient and the domain size. Under weak SST gradients, unforced self-aggregation emerges across the entire domain, similar to what was found in RCEMIP. As the SST gradient increases, the convective region narrows and is more confined to the warmest SSTs. At warmer mean SSTs and stronger SST gradients, low-frequency variability in the convective aggregation emerges, suggesting that simulations of at least 200 d may be needed to achieve robust equilibrium statistics in this configuration. Simulations with different domain sizes generally have similar mean statistics and convective structures, depending on the value of the SST gradient. The prescribed SST boundary condition is the only difference in the set-up between RCEMIP-II and RCEMIP-I, which enables comparison between the two; however, we also welcome participation in RCEMIP-II from models that did not participate in RCEMIP-I.
PIBM 1.0: An individual-based model for simulating phytoplankton acclimation, diversity, and evolution in the ocean
Authors: Sala Iria , Chen Bingzhang
Published: August 2024

Abstract. Phytoplankton is a diverse group of photosynthetic organisms and accounts for almost half of global primary production. However, most existing marine ecosystem models incorporate limited phytoplankton diversity, overlook phytoplankton evolution, and treat phytoplankton as concentrations instead of particles. Here we present an individual-based phytoplankton model that captures three dimensions of phytoplankton traits (size, temperature, and light affinities) and allows phytoplankton cells to mutate in a one-dimensional (1D) water column. Other components of this ecosystem include dissolved inorganic nitrogen, twenty size classes of zooplankton, and detritus, all modelled as Eulerian fields. This hybrid plankton model can reproduce the general seasonal patterns of nutrients, chlorophyll, and primary production in the subtropical ocean. We expect that this model will be a useful tool for studying phytoplankton physiology, diversity and evolution in the ocean.
Dynamic Fragility of a Slender Rock Pillar in a Sedimentary Rock Mass – from rock mechanics to seismic hazard
Authors: Jbara Alaa , Tsesarsky Michael
Published: August 2024

Abstract. Fragile geological features (FGF) are the only empirical data to validate seismic hazard analysis over prehistoric timescales. Precariously balanced rocks (PBR) are the most common FGF in practice, with fragility analysis based on rigid body rocking dynamics. FGFs evolved from sedimentary rock masses cannot be treated as rigid blocks, and rock mass properties should be considered in their fragility analysis. Contrary to PBRs, sedimentary FGFs received limited attention from the geological and engineering communities. This paper presents a comprehensive dynamic fragility analysis of a 42-meter-high pillar – the Ramon Pillar (Negev Desert, Israel). The pillar is comprised of a sedimentary rock mass with various discontinuities. An accurate finite elements (FE) model of the pillar (1.25.106 elements) was developed based on high-resolution aerial LiDAR scanning and in-situ measurements of rock elastic modulus along its entire height. The model was validated by comparing computational modal analysis with in-situ measurements of natural vibrations. The first mode of 1.3 Hz was precisely predicted. The second mode was predicted with a 10 % difference: 2.7 Hz calculated compared to 3 Hz measured. An a-priory assumption of rock elastic modulus (or back-calculation) or simplified geometries yielded unsatisfactory results. Following the successful validation, a fully dynamic fragility analysis of the pillar was performed, using recorded ground motions, to study the basal tensile stresses. Located in a region with two seismic sources, the Sinai Negev Shear Zone (SNSZ) and the Dead Sea Transform (DST), the pillar's fragility analysis was used to test regional seismic hazard estimates. It was found that an M 6 earthquake on the SNSZ will probably lead to breakage of the pillar at its base due to stresses exceeding its basal strength. Given a fragility age of 11.4 ky, our analysis challenges the assumption that the SNSZ can produce an M 6 event.
Mechanisms and intraseasonal variability in the South Vietnam Upwelling, South China Sea: the role of circulation, tides, and rivers
Authors: Herrmann Marine , To Duy Thai , Marsaleix Patrick
Published: August 2024

Abstract. Summer monsoon southwest wind induces the South Vietnam Upwelling (SVU) over four main areas along the southern and central Vietnamese coast: upwelling offshore of the Mekong shelf (MKU), along the southern and northern coasts (SCU and NCU), and offshore (OFU). Previous studies have highlighted the roles of wind and ocean intrinsic variability (OIV) in intraseasonal to interannual variability in the SVU. The present study complements these results by examining the influence of tides and river discharges and investigates the physical mechanisms involved in MKU functioning. MKU is driven by non-chaotic processes, explaining its negligible intrinsic variability. It is triggered first by the interactions of currents over marked topography. The surface convergence of currents over the southwestern slope of the Mekong shelf induces a downwelling of the warm northeastward alongshore current. It flows over the shelf and encounters a cold northwestward bottom current when reaching the northeastern slope. The associated bottom convergence and surface divergence lead to an upwelling of cold water, which is entrained further north by the surface alongshore current. Tides strengthen this circulation-topography-induced MKU through two processes. First, tidal currents weaken the current over the shallow coastal shelf by enhancing the bottom friction. This increases the horizontal velocity gradient and hence the resulting surface convergence and divergence and the associated downwelling and upwelling. Second, they reinforce the surface cooling upstream and downstream of the shelf through lateral and vertical tidal mixing. This tidal reinforcement explains 72 % of MKU intensity on average over the summer and is partly transmitted to SCU through advection. Tides do not significantly influence OFU and NCU intensity. Mekong waters slightly weaken MKU (by 9 % of the annual average) by strengthening the stratification but do not significantly influence OFU, NCU, and SCU. Last, tides and rivers do not modify the chronology of upwelling in the four areas.

El artículo ofrece una detallada y actualizada revisión sobre la aplicación de herramientas de ciencia de datos basadas en algoritmos de machine learning con el fin de predecir a corto y medio plazo la probabilidad de ocurrencia de crisis alimentarias en territorios de países con alta vulnerabilidad a este tipo de situaciones. Tras efectuar un breve repaso sobre la definición de seguridad alimentaria y sus métricas, se describen los principales esfuerzos internacionales para monitorear los factores agroclimáticos, económicos y sociopolíticos que más inciden en el deterioro alimentario de grupos de población o zonas geográficas concretas, y tras ello, generar alertas que desencadenen asistencia humanitaria que impidan el aumento del hambre y sus efectos en la salud de quienes la padecen. A partir de la revisión efectuada se propone un modelo de predicción adaptado al contexto los países Centroamericanos, en el que se consideran variables estructurales a ser utilizadas en la determinación anual de perfiles de vulnerabilidad alimentaria, así como otras sometidas a cambios permanentes y que por tanto permiten identificar shocks o perturbaciones que pueden impactar en la seguridad alimentaria. El modelo propuesto busca mejorar la toma de decisiones y la priorización de recursos y atención humanitaria en regiones con limitada disponibilidad de datos.
Studying the Relationship between some Biokinematic Variables and some Physical Measurements with the Level of Achievement in 25-meter Freestyle Swimming
Authors: Ibraheem Dhiaa Zaki , Abood Nawaf Owaid , Hammo Falah Taha
Published: August 2024

Study purpose. Swimming experienced significant growth and achievement in the late twentieth century and early second millennium, marked by the creation of advanced records. This progress is due to rigorous training, practical experience, and the utilization of modern scientific techniques and applied sciences such as biomechanics. This study aims to evaluate several bio-kinematic variables, physical measurements, and completion times in 25-meter freestyle swimming.
Materials and methods. Researchers used a descriptive approach to suit the nature of the research. The research sample consisted of 6 swimmers in the Nineveh Governorate applicant category. There was a digital camera with a speed of 60 images/second.
Results. There is a positive significant correlation between the anthropometric variable (arm length) with the total time. The researchers attribute this to the fact that the length of the distance of one stroke in swimming (25) meters depends primarily on the length of the total arm and thus, which will lead to covering the total distance of completion in the shortest possible time, given that the length of the arm is part of the length of the stroke.
Conclusion. The researchers concluded that the bio-kinematic variables studied played a very important role in achieving the best sample performance, even though the sample performance was generally poor. The large number of arm strokes in the study sample led to an increase in stroke frequency at the expense of decreasing the average length of arm strokes, thereby increasing completion time.

Published: August 2024

Purpose: To compare CT-guided core and fine-needle aspiration TTLBs in terms of complication rates, diagnostic adequacy, and dwell time and to investigate the independent risk factors associated with pneumothorax. Material and Methods: 247 consecutive biopsies (125 core and 122 FNA) were evaluated retrospectively. 17-18 G co-axial system was used in the core, and 19-22 G co-axial system was used in FNA biopsies. Lesions less than 10 mm were excluded since all were performed with FNA. The dwell time of each biopsy was noted. Results: The median age of the study group was 63 (183 males, 64 females). There was no significant difference between the core and FNA biopsy groups regarding age, gender, other parenchymal diseases, lesion localization, and traversed lung. Median dwell time was significantly shorter in the core biopsy. PX rate was 19.4%. Nineteen patients (7.7%) had PX requiring treatment. PX was not found to be related to the biopsy needle (core or FNA), even though its rate was significantly higher in the FNA. 5.5 minutes was the threshold dwell time for the occurrence of PX in the core biopsies. Dwell time more than this increased the risk by 4.9 times. Conclusion: Diagnostic adequacy and major complication rates of core biopsies are similar to FNAB. Although PX rates were higher in FNA biopsies, the biopsy type did not affect the risk. The threshold time for the safe procedure in core biopsies has been 5.5 minutes.

O cinema como força de ativação
Authors: Bôas Rafael Litvin Villas
Published: August 2024

O filme Cabra marcado pra morrer é analisado por meio da mediação dialética entre processo social e forma estética. Enquanto a versão ficcional (1964) foi uma resposta política ao assassinato de João Pedro Teixeira, a opção pela finalização no formato dedocumentário (1984) evidenciou as conseqüências brutais de interrupção da experiência de classe que se articulava. Por meio da estruturação da narrativa de uma diáspora, o documentário descortina progressivamente o percurso regressivo de nosso último ciclo de modernização conservadora e explicita os obstáculos à capacidade de organização da classe trabalhadora. Ao engatar dois tempos históricos, o filme articula um processo de acumulação de experiência, que tem como chave dois desfechos: a autoconsciência da recuperação do protagonismo da luta camponesa e o final de uma geração de combatentes.

Novos estudos, cada vez mais profundos e urgentes, longas enfermidades e por fim a morte impediram-no de terminar a obra toda, tendo sido Engels quem editou esses dois volumes com base nos manuscritos inéditos deixados pelo amigo. Eram anotações, esboços, notas, ora capítulos inteiros concluídos, ora breves observações feitas de passagem como faz um pesquisador para sua compreensão pessoal – um trabalho intelectual poderoso que, com interrupções prolongadas, cobria o largo período de 1861 a 1878.
El marxismo frente a la utopía realista de John Rawls
Authors: Lizárraga Fernando
Published: August 2024

Con calculada desmesura, el filósofo británico G. A. Cohen ha escrito recientemente que Teoría de la Justicia, de John Rawls,1 merece ser considerada, junto con la República de Platón y el Leviatán de Thomas Hobbes, como una de las obras fundamentales de la filosofía política.2 La principal razón que aduce para incluirla en esta tríada es que, en términos hegelianos, la teoría del pensador de Harvard representa el punto en que la política de la izquierda liberal norteamericana y de la socialdemocracia europea alcanza conciencia de sí misma. Más allá de la validez de esta afirmación, el lugar concedido a Rawls por parte de uno de los más sofisticados filósofos marxistas de nuestros días ilustra el impacto del pensamiento rawlsiano sobre el socialismo y el materialismo histórico en particular.

Charting the Universe of Metal Music Lyrics and Analyzing Their Relation to Perceived Audio Hardness
Authors: Czedik-Eysenberg Isabella , Wieczorek Oliver , Flexer Arthur , Reuter Christoph
Published: August 2024

We analyze the relationship between the musical and the lyrical content of metal music by combining automated audio feature extraction and quantitative text analysis on a corpus of 124,288 song lyrics from this genre. Based on this text corpus, a topic model is first constructed using Latent Dirichlet Allocation (LDA). For a subsample of 503 songs, scores for predicting perceived musical hardness (heaviness) are extracted using an audio feature model and corroborated via listening tests. By combining both audio feature and text analysis, we (1) offer a comprehensive overview of the lyrical topics present within the metal genre and (2) are able to establish whether levels of hardness are associated with the occurrence of particularly harsh (and other) textual topics. Twenty typical topics are identified and projected into a topic space using multidimensional scaling (MDS). Positive correlations are found between musical hardness and textual topics dealing with “brutal death,” “dystopia,” “archaisms and occultism,” “religion and satanism,” “battle,” and “(psychological) madness,” while there is a negative association with topics like “personal life” and “love and romance.” Further, we show different prevalences of the identified topics within different metal subgenres. In summary, this article presents the first comprehensive computational corpus study of musical and lyrical content in metal music.

Askeri üsler, komutanlıklar ve içerisinde görev alan personelin barındığı, eğitim ve tatbikatların yapıldığı yerler olarak tanımlanabilir. Üç tarafı denizlerle çevrili olan ülkemiz için üs yeri seçimi oldukça önemli ve stratejik bir karardır. Bu çalışmada, ülkemizin çıkarlarını ve güvenliğini muhafaza etmek, doğalgaz kaynaklarının korunması ve oluşabilecek diğer tehditlere karşı Karadeniz Bölgesi’nde üs yeri seçimi amaçlanmıştır. Alternatif 12 limanın sosyokültürel yapıları analiz edilmiş ve uydu görüntüleri incelenerek coğrafi yapıları incelenmiştir. Literatür taraması ve uzman görüşü alınarak belirlenen 18 kriter “operasyonel” ve “stratejik” olarak sınıflandırılmıştır. Kriter ve alternatiflerin tespit edilmesinden sonra Çok Kriterli Karar Verme (ÇKKV) yöntemlerinden Analitik Hiyerarşi Prosesi (AHP) ile kriterler ağırlıklandırılmış ardından bir başka ÇKKV yöntemi olan COPRAS (Complex Proportional Assessment) ile alternatifler sıralanmıştır. “Kanal derinliği” operasyonel olarak önem derecesi bakımından en yüksek öneme sahip kriter olarak değerlendirilmiştir. Stratejik olarak en önemli kriter ise “doğalgaz kaynaklarına uzaklık” olarak tespit edilmiştir. Operasyonel, stratejik ve genel sıralama ayrı ayrı elde edilmiş ve sonuçlar karşılaştırılarak yorumlanmıştır. Tüm sıralamalara göre en sondaki alternatif İnebolu olmuştur. En iyi alternatif ise operasyonel sıralamaya göre Karadeniz Ereğli, stratejik sıralamaya göre Samsun, genel sıralamaya göre Çamburnu olmuştur. Çalışmanın karar vericilere fayda sağlaması amaçlanmaktadır.
SINCRETISMO RELIGIOSO: UMA PESQUISA SOBRE AS ORIGENS DAS INFLUÊNCIAS RELIGIOSAS E CULTURAIS QUE DERAM ORIGEM AO CRISTIANISMO NO BRASIL

Published: August 2024

Este artigo apresentará uma pesquisa bibliográfica a respeito do sincretismo religioso presente em meio ao cristianismo no Brasil. O objetivo principal é identificar as origens dessa miscigenação cultural e religiosa que acaba dando o seu próprio tempero ao que está escrito no livro sagrado utilizado pelos cristãos, a Bíblia. Será apresentado através deste artigo um panorama acerca da colonização brasileira e as heranças culturais provindas dessa colonização que formaram a base do cristianismo no Brasil. Além das influências causadas e impostas pelos colonizadores europeus mediterrâneos portugueses há pouco mais de cinco séculos, serão enfatizadas também as influências dos africanos que foram trazidos ao Brasil colonial da época na condição de escravos, e que trouxeram junto consigo além de sua cultura, as suas crenças religiosas, seus costumes e ritos. E também acerca das influências das religiões e culturas indígenas. Com isso, não surgiram apenas as chamadas religiões afro-brasileiras, mas surgiram também mesclas e misturas de distintas crenças e religiões e que são responsáveis por esse sincretismo religioso que será abordado neste artigo.
Non(sense)-Places
Authors: Sánta Balázs
Published: August 2024

Space as the locus of a game (“field”) has been a common metaphor in analysing Victorian nonsense literature: Elizabeth Sewell’s 1952 monograph incorporated it already in its title, The Field of Nonsense, while Susan Stewart’s study, Nonsense (1978), identifies discursive operations of nonsense-making “within a closed field.” However, little has been said about space as a motif (or topos) in the primary texts of nonsense. Although Gillian Beer in her 2016 book Alice in Space treats certain spatial aspects of Lewis Carroll’s Alice books, the spaces of Edward Lear’s limericks are yet to be explored. The paper attempts such an exploration by invoking anthropologist Marc Augé’s term “non-place” (non-lieu) from his 1992 study (first published in English in 1995 with the title Non-Places: An Introduction to Supermodernity). Augé describes a central part of what he calls supermodernity within the context of anthropology, a field apparently far away from my primary concern. Yet it is not difficult to recognise similarities between lonely spots of modern cityscape such as train stations, shopping malls, airplane cabins, or driver’s seats—and the places in Lear’s poems like the snippets of countryside in the limericks or the Great Gromboolian Plain. Augé’s analyses of excess of space (as well as time), especially space perceived in travel, and of places unconcerned with (social) relations, history, or identity, where solitude reigns, ring familiar when reading Lear’s limericks and nonsense songs. By incorporating the main qualities of the non-place, this paper offers an interpretive framework for Lear’s nonsense poetry that can be potentially extended to Victorian nonsense literature in general.
Cruising and Code
Authors: Clark Ian M.
Published: August 2024

In homophobic cultures, “cruising,” or the clandestine pursuit of sexual relations with strangers, is both a pleasurable act and a means of connecting with other queer individuals. This article utilises cruising as an analytical and methodological framework through which to examine Eric Stenbock’s “The True Story of a Vampire” (1894) as the author’s allegorical effort to combat his social and sexual isolation. Reading Stenbock’s text through this subcultural queer practice reconfigures the archetypal “stranger”—here, the vampire Count Vardalek—from simply threatening to also a personification of potential pleasure and queer community. This reading expands upon recent work in queer theory that argues the artistic works of fin-de-siècle aesthetes were a means of gaining sexual self-knowledge and a sense of personal independence within systemic oppression. These critical re-readings call attention to the often subliminal or coded language of queer expression within art; as such, this article posits the benefits of applying queer practices like cruising to literary analysis, particularly toward texts only publishable if their queer themes remain subtextual.

Allah Almighty bestowed the seal of prophethood upon the beloved Prophet Muhammad (peace be upon him), and in the Quran, He took it upon Himself to safeguard this honor until the Day of Judgment: "Muhammad is not the father of any of your men, but he is the Messenger of Allah and the Seal of the Prophets" (Quran, Al-Ahzab 33:40). This profound honor and responsibility ensure that no one can ever challenge or alter the finality of prophethood, as Allah Himself has guaranteed its protection. In pursuit of this sacred mission, the “Shuban Khatm-e-Nubuwwat Institute” dedicates its full efforts and resources to protecting the finality of prophethood. The institute is tirelessly working day and night to guide and support individuals who have converted from Qadianism to Islam, assisting them in their religious, social, and economic development. Their work involves not only providing proper Islamic education and guidance but also offering educational support, healthcare services, and employment opportunities to help these individuals lead dignified lives within society.
The organization’s efforts are focused on clarifying the misconceptions of Qadianism and promoting the true teachings of Islam. Key initiatives include educational assistance, healthcare provisions, and job opportunities, which collectively bring significant positive changes to the lives of converts from Qadianism. This paper aims to provide a comprehensive overview of the Shuban Khatm-e-Nubuwwat Institute's activities and their impact, highlighting how their endeavors have led many to embrace Islam and live a positive and fulfilling life.
Asom Gana Parishad: The Trajectory of India’s Endangered Ethno-regional Party

Published: August 2024

The existential crisis of the Asom Gana Parishad (AGP), the prominent ethno-regional party in Northeast India, demonstrates that ethno-regionalism may tender only short-term political dividends to the party unless it transforms into a party to carry out a vision of development that would address the material well-being of people. In other words, the ideology and mobilisation of an ethno-regional party may not be sustainable if it deviates from its strategy from the everyday life process of development. Moreover, the BJP’s glowing strategy of championing ethno-regionalism along with its Hindu nationalist ideology and its alliance with the AGP cost more adverse impact on the latter’s mass base and thereby dwindling its electoral space in the Assam politics.
