Bhosale, Pradeep. "Deploying Stateful Applications in Kubernetes: Best Practices with StatefulSets." INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT 09, no. 02 (2025): 1–9. https://doi.org/10.55041/ijsrem41457.
Full textAbstract:
As container orchestration transitions from experimental deployments to mission-critical, large-scale operations, running stateful workloads in Kubernetes becomes a pressing topic. Historically, Kubernetes excelled at stateless microservices, quickly scaling ephemeral pods. However, many real-world systems rely on persistent data; databases, caches, key-value stores, and distributed queues. StatefulSets are a Kubernetes feature specifically designed to handle pods requiring stable identities, ordered startup, and persistent storage. Deploying these stateful applications demands nuanced architectural decisions, from volume management and data replication to orchestrating rolling upgrades while preserving data integrity. This paper provides a comprehensive, hands-on guide to best practices with StatefulSets. We begin by comparing stateful and stateless workloads, illustrating how StatefulSets differ from Deployments or ReplicaSets. We then cover persistent volumes, storage classes, node affinity, scaling, advanced update strategies, and the interplay between stateful containers and multi-environment DevOps pipelines. Along the way, we highlight anti-patterns like overusing a single shared volume or ignoring readiness checks and propose real-world solutions drawn from production experiences. The aim is to furnish architects, operators, and developers with the insights and practical steps necessary to reliably run mission-critical, data-centric services in a Kubernetes ecosystem.

Full textAbstract:
Microservices architecture has revolutionized software development by enabling scalable, modular, and resilient applications. Traditional monolithic systems rely on centralized security controls, but microservices’ decentralized architecture is characterized by frequent deployments, horizontal scaling, and containerized environments that exposes vulnerabilities such as misconfigured APIs, insecure secrets, and inconsistent deployment practices. These risks are exacerbated by the rapid evolution of cloud-native technologies, where manual configuration processes and ad-hoc updates create exploitable gaps. This paper examines the complexities of secure configuration management in microservices, emphasizing the interplay between dynamic infrastructure, DevOps workflows, and compliance requirements. Key challenges include managing secrets across distributed services, ensuring configuration consistency in ephemeral containers, and mitigating insider threats through automated governance. To address these issues, the study advocates for integrated solutions such as infrastructure-as-code (IaC) frameworks, centralized secrets management systems, and continuous compliance auditing via CI/CD pipelines. By aligning security with agility, organizations can enforce least-privilege access, automate configuration drift detection, and safeguard sensitive data in hybrid cloud environments. The analysis underscores the necessity of adopting adaptive security strategies to counter evolving threats while maintaining operational resilience. Findings highlight the role of orchestration platforms and AI-driven tools in future-proofing microservices architectures, ensuring robust security without compromising scalability.

Sathe, Mohini M. "Serverless Web Development." INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT 09, no. 06 (2025): 1–9. https://doi.org/10.55041/ijsrem50975.
Full textAbstract:
Serverless web development marks a significant transformation in how modern applications are built by eliminating the burden of server management for developers. This review examines the progression, advantages, drawbacks, and potential of serverless computing, with a primary focus on Function-as-a-Service (FaaS) and Backend-as-a-Service (BaaS) models. The main aim is to evaluate current academic and industry trends, draw comparisons between leading technologies, and provide synthesized insights into their real-world usage. The analysis is based on diverse scholarly publications, performance studies, and practical implementations. Key themes include scalability, operational cost, security challenges, and implementation scenarios. While serverless systems promote faster development and operational simplicity, limitations such as cold start delays, monitoring difficulties, and dependency on specific vendors remain significant concerns. This review identifies areas requiring further investigation and offers guidance for future research, aiming to deepen the understanding of serverless frameworks. It serves as a resource for both researchers and developers interested in adopting or refining serverless methodologies across a variety of use cases. As the demand for rapid, scalable, and cost-effective digital solutions increases, serverless computing has emerged as a strategic approach for organizations seeking to streamline DevOps processes and focus more on business logic than infrastructure. Its event-driven nature and automatic scaling capabilities align well with the dynamic needs of web-based services, making it a suitable architecture for microservices, real-time APIs, and data processing tasks. However, achieving consistent performance and maintaining observability in ephemeral environments present ongoing challenges that must be addressed through innovation in tooling and cross-platform standardization. Key Words: Serverless Computing, Function-as-a-Service (FaaS), Backend-as-a-Service (BaaS), Cloud Computing.

"Quantifying Intermittent Flow Regimes in Ungauged Basins: Optimization of Remote Sensing Techniques for Ephemeral Channels Using a Flexible Statistical Classification." Remote Sensing 15, no. 24 (2023): 5672. http://dx.doi.org/10.3390/rs15245672.
Full textAbstract:
Intermittent and ephemeral channels are a critical component of the global hydrologic network. The dominant feature in dryland environments, ephemeral channel transmission loss facilitates aquifer recharge. Characterizing flow intermittency improves groundwater storage estimates; however, limited gauging of intermittent systems impedes this understanding. This research develops an improved classification for surface flow, optimized for ephemeral systems using linear discriminant function analysis and remotely sensed imagery. It further applies this methodology to assess temporal and spatial flow patterns across the Souss channel, an ungauged, ephemeral system in central Morocco. Linear discriminant function analysis demonstrates high predictive accuracy for Landsat imagery, with significantly improved classification success as compared to the Modified Normalized Difference Water Index. Application to the Souss channel from 1984 to 2022 points to a decreasing trend in flow frequency. Despite this change, flow events remain concentrated within the wet season, critical for regional aquifer recharge. Spatial flow characteristics further support sustained infiltration, with the majority of events focused within the upstream channel section during both dry and wet seasons. Decreased occurrence moving downstream highlights the likely impact of additional factors such as transmission loss, evapotranspiration, and agricultural abstraction contributing to channel intermittency.

Full textAbstract:
Spring ephemerals take advantage of the high light levels available in the spring by completing the aboveground portion of their lifecycle before the canopy develops and while few other understory plant species are growing. The spring is marked by high resource availability, yet spring ephemerals are variably abundant throughout forests. Research indicates that canopy conditions can influence the growth of spring ephemerals; consequently, we tested whether the variation in canopy conditions predicted variation in the abundance of Erythronium americanum Ker Gawl. across 50 forest plots. We also tested whether the specific leaf area (SLA) of E. americanum in plots was predicted by variation in plot-level canopy conditions, reflecting E. americanum‘s ability to adapt to different canopy conditions. The abundance of E. americanum was significantly lower in the plots with greater hard canopy closure (i.e., permanent cover: tree architecture + evergreen leaf cover), and significantly higher under canopies that reached full development earlier. Canopies with greater hard canopy cover at the start of the growing season were associated with significantly higher SLA, quantifying local adaptation by E. americanum to variable canopy conditions. Erythronium americanum takes advantage of the high light levels available in the spring. It is unclear at this time why higher abundance of E. americanum is associated with canopies that close earlier.

Full textAbstract:
Granular assemblies can experience complex failure patterns along a given loading path, with a distribution of ephemeral inertial events marked by local outbursts in kinetic energy. However, investigating such mechanisms appears to be necessary to understand how a certain failure mode develops in a granular material. Using a discrete element method, this study highlights several microstructure reorganizations before the specimen reaches a proper failure state. Meso structures have proven to be efficient to understand the elementary mechanisms responsible for these outbursts in kinetic energy. Strain–like and stress-like quantities are thus defined at a mesoscale and they are used to characterize the nucleation and propagation of these local microstructural events.

Full textAbstract:
In the present study main parameters of reproductive biology as features of embryological structures and processes as well as the pollen and seed viability of Alkanna tinctoria, an endangered useful species of Bulgarian flora were established. In its studied Bulgarian populations pollen viability above 90% and seed viability – between 32% and 64% were determined. The anthers are tetrasporangiate and their wall develops according to Dicotyledonous-type, consisting of an epidermis, fibrous endothecium, an ephemeral middle layer and secretory tapetum. The microsporogenesis is simultaneous and in the anthers tetrahedral and isobilateral microspore tetrads are formed. The mature pollen is threecelled at shedding stage. The ovule is anatropous, teniunucellate, unitegmic. Embryo sac (ES) develops according to the Polygonum (monosporic)-type. The embryo development follows the Asterad-type. The endosperm in the mature seeds has been completely consumed. As a result of the present study A. tinctoria is characterized as a sexually reproducing species.

Full textAbstract:
Analyses of contemporary societies stress the dynamics of cultural changes. “Temporary collective fascinations” (such as hula-hoop, Rubik’s cube) known in American sociology as “fads”, may be regarded as examples of a model of ephemeral culture. They emanate from such social values as: progress, change, “being hip”. Their development is accompanied by the emergence of a specific system of values, norms, meanings, patterns of behavior and emotions. The axiological and semiotic consensus which develops around these fads is usually short-lived and a current object of fascination is abandoned once it becomes “boring”. Collective fascinations should not be treated solely as creations of manufacturers or of the media as such phenomena were observed in remote history.

Full textAbstract:
Resistances to sexual and gender rights are shifting and need new theorisations. This article develops the analytical concept of heteroactivism by exploring its relation to abortion debates in Ireland. Heteroactivism as an analytical category examines resistances to sexual and gender rights that seek to reiterate the place of the heteronormative family (both in terms of gender norms and heterosexuality) through activisms that can stand against new legislative orders. The article investigates three texts to explore how the ‘Vote No’ campaign in Ireland discussed ‘loving both’, but in the main thrust of the poster campaign instead focused on the foetus as an ‘unborn child’. Using textual and visual analysis, we show the creation of Ireland through seeking to ‘love both’ and create a distinction from the dangers, and foreign contagion, of England. The article concludes by arguing that ongoing work is needed to explore heteroactivism and its diverse manifestations, including in abortion debates.

Full textAbstract:
Abstractδ18O values of sulfate minerals from a 186-m core (past 200,000 years) in Death Valley varied from +9 to +23‰ (V-SMOW). Sulfates that accumulated in the past ephemeral saline lake, salt pans, and mud flats have relatively low δ18O values similar to those of present-day local inflows. Sulfates that accumulated during two perennial lake intervals, however, have higher δ18O values, reflecting changes in temperature, lake water levels, and/or sulfur redox reactions. Over the same time interval, the δ18O record for sulfate had excursions that bear similarities to those found for carbonate in the Death Valley core, marine carbonate (SPECMAP), and polar ice in the Summit ice core, Greenland. The δ18O record differed considerably from the records reported for carbonate at Owens Lake and Devils Hole, which probably relates to different water sources. Death Valley, Owens Lake, and Devils Hole are responding to the same climatic changes but manifesting them differently. In Death Valley sediments, the isotopic composition of sulfate may have potential as an indicator of paleoenvironmental changes.

Full textAbstract:
This article develops the concept of cyborg activism as novel configuration of democratic subjectivity in the Information Age by exploring the online collectivity Anonymous as a prototype. By fusing elements of human/machine and organic/digital, the cyborg disrupts modern logics of binary thinking. Cyborg activism emerges as the reconfiguration of equality/hierarchy, reason/emotion and nihilism/idealism. Anonymous demonstrates how through the use of contingent and ephemeral digital personae hierarchies in cyborg activism prove more volatile than in face-to-face settings. Emotions appear as an essential part of a politics of passion, which enables pursuing laughter and joy, expressing anger and experiencing empowerment as part of a reasoned, strategic politics. Anonymous’ political content reconfigures nihilist sentiments, frustration and political disenchantment, on one hand, with idealist world views, on the other. This enables the cohabitation and partial integration of a great diversity of political claims rooted in various ideologies.

Full textAbstract:
The concept of the screening of interparticle interactions has its origin in electrolyte and plasma theories. The most known example is the Debye-Hückel screening of the potential of the resting test charge provided with the availability of charges of the opposite sign and the total electroneutrality of the plasma. When this charge is moving, the static Debye screening decreases and an anisotropic dynamic screening develops due to excitation of waves of charge density. As a result, an effective potential of the positive moving ion becomes alternating with a characteristic length of space oscillations of order of the Debye length (Peter, 1990). Such dynamic screening is due to perturbations of charges of both signs by the varying field of moving test charge. This effect does not call for an electroneutrality of the system and is associated with the long-range character of the Coulomb interaction potential only.

Departing from the work of Georg Simmel on Rembrandt, we try to characterize self-portrait as a moment of inner confrontation and of inner inquiry on our inner self and individuality. All self-portraits are pervaded by the ephemeral character of life, where death is constantly present. The self-portrait is born from the drawing and the drawing develops it in a continuity where the past juts out in the present. The human face is the sum of a duration that moulds its traits, its expression and its variation in a tension that brings the past to a present that is now remade. Thus, the self-portrait, more than the portrait, enables the possibility to transmit what the subject has of unique as an individual. In this sense, the self-portrait represents the knowledge of an individuality felt in the process of life, individuality withdrawn from the stream of life and in the unity of its existence.

Full textAbstract:
AbstractTimbre is a key aspect of musical practice and aesthetics. Artists use instrumentation, vocal technique, and production technology to create precise tone colours; listeners are able to identify genres, artists and connotations through timbre. However, critical assessment of its ephemeral musical agency is scarce. This article develops a theory of timbre. Goth music, which privileges tone colour in production, performance, and aesthetic, is a case in point for the ungraspable agency of this musical parameter. Timbral analyses of two goth tracks, Veil of Light's ‘Cold skin’ and Sopor Aeternus and the Ensemble of Shadows's ‘Dreamland’, will assess tone colour's relation to identity and difference (Walser), signification and corporeality (Barthes, Ihde), and the surplus of meaning and embodiment (Dolar). The article will argue that timbral aesthetics are characterised by the paradox of present absence: it indicates corporeality and meaning but simultaneously exceeds both. Tangible but also disembodied, immersive but also meaningless, it is no wonder that goth exploits timbre's dark agency.

Full textAbstract:
ABSTRACT: In May 1818, Joseph Arnold—a surgeon and naturalist working under British statesman Thomas Stamford Raffles—came across what he called the “vegetable of the prodigy world,” a flower so unbelievable in its size, putrid odor, and fleshiness that it would challenge the limits of floral life for colonial naturalists thereafter. Tracing the material history of the so-called corpse flower, Rafflesia arnoldii , over the course of the eighteenth and nineteenth centuries and its place—or lack thereof—in colonial collections, this article explores how natural historical knowledge develops when specimens cannot be fully collected, described, or possessed outside of the field. Facing a lack of physical evidence and the utter inability to preserve, pack, and ship the massive, stinking, and ephemeral corpse flower to Britain and Europe from its Sumatran home, naturalists like Arnold struggled with disbelief and self-doubt while moving through colonial networks of exploration, competition, and death in the rainforests of Southeast Asia. Loss, this article argues, held significant weight in colonial collecting, challenging notions of material abundance in herbaria and natural history museums.

Full textAbstract:
This paper presents materials from one of the Palaeolithic sites discovered by the author in the late 1980s and early 1990s in Crimea. The Hamak-Koba sediment pack was once tested, and some archaeological materials were recovered. These are few but rather informative and have been published for the first time now. Judging by the available data, Hamak-Koba is a short-term site of a mobile group of hunters. The remains of shells of the land snail Helix vulgaris, which were probably consumed as food, may indicate the Epipalaeolithic or Mesolithic age of the site and probably exclude the winter season of its visitation. The technical and typological features of the stone artefacts found, including blades with indications of intensive use and burnt endscrapers, are consistent with the assumption of the site's age therefore positioned somewhere between the Late Pleistocene and Early Holocene. An undisturbed horizon with artefacts and hearth remains was discovered during the test pitting. It also turned out that a significant part of the shelter is practically devoid of culture-bearing deposits. The locality suggests one of the points visited by early hunters while travelling through the exploited territory in search of resources. This version is supported by the features of the stone artefacts, which show signs of special selection and therefore belong to a part of a mobile toolkit, traces of intensive wear on them, and the location of the site in a rock shelter near convenient access to a plateau providing dominating heights and good observation points, although far from water sources.

Full textAbstract:
Based on twenty-one months of ethnography and interviews with transborder commuters in the San Diego-Tijuana border region, this article develops the notion of “queer limitrophic dwelling.” Building on queer, feminist, and transnational scholarship on home and dwelling, the article demonstrates how transborder commuters negotiate white Euro-American renditions of home and domesticity that emphasize privacy and fixity as the “proper” ideal vis-à-vis the home. It argues that transborder commuters enact several life-making or queer tactics — practices not necessarily enacted by LGBTQ+ subjects — that spatially decentralize their homes in Tijuana by harnessing transborder kinships and by making queer use of spaces and objects at the San Ysidro port of entry and across San Diego. In doing so, transborder commuters’ domestic labor practices produce ephemeral mobile dwellings when needed, allowing them to navigate multiple temporalities and survive normalized conditions of displacement occasioned by US land ports of entry and racial capitalism. Importantly, queer limitrophic dwelling highlights the US-Mexico borderland's capabilities to nourish and maintain life while also being a product of US settler colonialism engendered through historic and ongoing border violence and exclusion.

Full textAbstract:
Robert Burns's decision to emigrate to Jamaica in 1786 as a slave-driver is well known, and is increasingly debated as Scotland develops its understanding of its direct and indirect roles in the transatlantic slave trade and Black chattel slavery. The stories, and even the names, of the Black people of that period (servants and tradesmen) are typically more ephemeral than those of Burns and his friends and patrons, but it would be wrong to assume that there were no Black people living and working in Ayr and its environs in Burns's day. While the Black population across Scotland was small (commentators suggest around seventy individuals against some fifteen thousand in England & Wales), contemporary records show that over a dozen lived and worked in Ayrshire. While there is no concrete evidence in the Poet's writings, this study shows that it is highly likely that Burns saw some of these people on the streets, that he met the biracial children of the manumitted Black man Scipio Kennedy, and that he was present at the baptism of a Black man, John Cartwright, in Mauchline Kirk in 1784.

Full textAbstract:
Primula veris (Primulaceae) is a valuable medicinal plant. The main characteristics for assessing the reproductive potential (embryological features; mode of reproduction; pollen and seed viability) and the genetic diversity of populations of the species from Bulgaria were studied. The anthers are tetrasporangiate. Their wall development follows the Dicotyledonous-type and consists of: epidermis, a fibrous endothecium, an ephemeral middle layer and a secretory (glandular) tapetum. After meiosis in pollen mother cells and simultaneous microsporogenesis tetrahedral tetrads are formed predominantly in the anthers. Many ovules (approximately 20) develop in the unilocular ovary and are anatropous, tenuinucellate and bitegmic. The embryo sac (ES) develops after Polygonum (monosporic)-type from the chalazal cell of linear megaspore tetrad in the ovule. After double fertilization, a Caryophyllad-type embryo and initially nuclear endosperm form. In the studied populations, high pollen viability of more than 95% was established. Extremely low viability (about 4%) of the seeds obtained from natural populations was established. The results reveal P. veris to be a predominantly amphimictic (sexually reproducing) species, although rare vegetative propagation is also observed. As a result of this study, essential data were obtained about the reproductive structures and processes and for assessing the reproductive potential of P. veris.

Full textAbstract:
This is the first embryological report of the Grewioideae subfamily, which is meant to contribute to the characterisation of the genera Corchorus, Luehea and Triumfetta. Ovule and female gametophyte development in C. argutus, L. divaricata and T. semitriloba was analysed. The ovules of all species are anatropous, bitegmic and of crassinucellate mixed type. The micropyle of the studied species is formed by the outer integument (exostome). The ovule of L. divaricata differs from those of the other two species because the chalazal tissue expands forming a cap, which gives rise to a wing in the seed. All species present one hypostase. The megaspore mother cell gives rise to a linear megaspore triad in C. argutus and L. divaricata, whereas in T. semitriloba, triads and diads can be observed in the same ovule. The chalazal megaspore develops a seven-celled and eight-nucleate female gametophyte corresponding to the Polygonum type. The synergids of L. divaricata have hooks and a conspicuous filiform apparatus. The antipodal cells in C. argutus are persistent, whereas in the other species, they are small and ephemeral. The embryological characters are compared with those of other taxa within the family and the megagametophyte formation in these species is discussed.

Full textAbstract:
This article explores the rise of a new generation of practices combining architecture, design, and art, trying to answer the transition issues faced by society. It develops original operating procedures, including public participation. In doing so, those so-called “specialised” professions expand their sphere of operation and incorporate more immaterial dimensions and resources. The main objective of the article is an attempt to clarify how participation is embodied in specific intervention methods, within those experimental practices. The article will take as a case study a participatory project taking place in a retirement home and aimed at building a mobile third place that brought together various professionals coming from those experimental practices. The study of the participatory project will outline three devices and methods supporting the participation work, as follows: the use of permanence, the use of the prototype and self-construction, and the conception of ephemeral production. The article suggests that based on their analysis, we can understand what architects and designers “manufacture” through the agency of participation. Or more accurately, what participation “manufactures” in those experimental practices. The main result of the article is that the participatory project is more concerned with the motives and aspirations of the design activity, its methods and processes, its context and socialisation than it is with what would be classically considered as the outcome or result (the work, the realisation, the production, the built).

Full textAbstract:
Around the world, covers have become advertisements for their books. The dignity that characterizes something self-contained, lasting, hermetic — something that absorbs the reader and closes the lid over him, as it were, the way the cover of the book closes on the text — has been set aside as inappropriate to the times. The book sidles up to the reader; it no longer presents itself as existing in itself, but rather as existing for something other, and for this very reason the reader feels cheated of what is best in it. Theodor AdornoIn his last book, at the end of a successful, literary career, Martial asks in regard to his own genre of epigram: ‘quid minus esse potest?’ (‘What can be humbler?’, 12.95). Such self-disparagement is not necessarily surprising, since there is no reason to imagine that Martial's success as an epigrammatist would alter his genre's place in the traditional hierarchy of literary seriousness. Martial's denigration of his own oeuvre, however, goes beyond consciousness of epigram's status as a low genre. The epigrammatist not only registers his genre's formal rank, he develops fully articulated fictional scenarios depicting the nature of his writing and its role in society. According to the most salient and pervasive fiction characterizing Martial's work, epigram is an ephemeral form of literature embedded in specific, social contexts, and dedicated to immediate uses.

Abstract: This article examines the intersection of empire, national identity, performance, and cultural representation through an analysis of the Filipino Rough Riders in Buffalo Bill’s Wild West . Drawing on historical material—including newspaper articles and illustrations, photographs, and Wild West ephemera—this article explores how and why Filipino performers were included in Buffalo Bill’s Wild West and how they were represented by the exposition, the press, and the performers themselves. It develops the concept of “playing Filipino,” a phrase that adapts and alters the notion of “playing Indian,” to capture the interactive process of performing not only racialized types for white-dominated audiences and institutions, but also the resistant and creative activity of embodying Filipino-ness through self-crafted style and aesthetic appearance. This study advances transnational Asian American studies by presenting new ways of thinking about turn of the twentieth-century Filipino performers and their relation to US imperialism through cultural institutions and popular entertainment like traveling Wild West shows, and it also expands American West scholarship by considering how Asian subjects figured into constructions of US domestic and overseas frontiers during times of war.

 In contemporary cities, closure and individualism predominate at the expense of ‘mixing’ and inclusion. By structuring the territories around the principles of speed and globalization, the Net has generated ‘weak links’ of social interaction that are reflected in a public space devoid of identity, used quickly and in solitude, dominated by the fear of the difference and by indifference. In opposition to these dynamics, the importance of collaboration emerges, the central value of an open city in which technology and society become resources to reconcile global and local, individual and community. In this direction, at the scale of public space, the collaborative actions of urban events and the bottom-up practices work on the immaterial component of the project: co-design processes guide the interventions of citizens, collectives and associations in the rediscovery of identity values, cultural meanings and emotions associated with places. The public space becomes a place of interaction and meeting again, experiencing a new culture of living through ‘fixed-time architecture’ which, while meeting the needs of the moment, imagine change. Ephemeral and temporary re-signify ordinary landscapes through collective creativity and direct action on places and, if on the one hand they express the acceleration of our era, on the other they become forms and languages of a project that, in an ecological vision, fits with the rhythms of nature, where everything changes and evolves to contribute to life.

Full textAbstract:
A floristic study of marine macrophytic algae and Cyanobacteria in the splash and intertidal zones at Luhuitou reef, Sanya Bay, Hainan Island, China, was conducted during the rainy and dry seasons of 2008−2012 utilizing 148 of the most common species. Macrophytic algal diversity increased from the splash zone to the low intertidal zone, while cyanobacterial diversity decreased. In the upper and middle intertidal zones, the dominant species (primarily highly productive ephemerals) changed frequently throughout each year. In the low intertidal zone, the dominant species (mainly annual fleshy, foliose and coriaceous forms) also changed. In the dry season, species numbers were 33% higher than in the rainy season. During the rainy season, Cyanobacteria dominated the splash zone, while green and red algae dominated in increasing numbers from the upper to the low intertidal zones. During the dry season the splash zone was devoid of all macrophytic algae, and only one species of Cyanobacteria survived. In the upper intertidal, Cyanobacteria and red algae prevailed, while in the mid and low zones, red and green algae were the most diverse. In spite of heavy pollution in Sanya Bay, there was no evidence of dramatic changes in species numbers or composition, and the marine flora was similar to that of unpolluted regions in the Indo-Pacific.

Walter Bagehot divided the English constitution into two parts, the “dignified” and the “efficient.” The sovereign and the House of Lords were the dignified or the showy parts, imposing spectacles designed to serve as reminders of a glorious past and to impress an uneducated populace with the authority of the state. The cabinet and the House of Commons were the efficient parts, where the real work went on, where men of business transacted affairs of state using the authority obtained by the dignified parts. So he wrote in the years preceding the second Reform Bill, when it was conventional to speak of the rudeness and unruliness of an uneducated people and of the hazards of admitting them to the franchise. Yet his book, animated in such large measure by the debates on parliamentary reform of the late 1860s, remains a much-quoted authority on the English constitution today.Perhaps one among the reasons for its enduring popularity is that he expressed so neatly a notion that certainly existed before as well as in his time and that survives today, namely, that governmental activity can be divided into ceremonial and political parts. The one is opposed to the other as pleasure is to business, as emptiness is to substance, as illusion is to reality, as artifice is to plain speaking. In affairs of state, the adjective “ceremonial,” when attached to words like “head of state” or “official,” has come to mean empty figurehead or powerless placeholder. Ceremonies of state—coronations, jubilees, openings of Parliament—are picturesque and pleasant but essentially ephemeral, devoid of anything powerful other than that which is powerfully sentimental, colorful, and evocative.

Full textAbstract:
Context. The apparent close encounters of two satellites in the plane of the sky, called mutual approximations, have been suggested as a different type of astrometric observation to refine the moons’ ephemerides. The main observables are then the central instants of the close encounters, which have the advantage of being free of any scaling and orientation errors. However, no analytical formulation is available yet for the observation partials of these central instants, leaving numerical approaches or alternative observables (i.e. derivatives of the apparent distance instead of central instants) as options. Aims. Filling that gap, this paper develops an analytical method to include central instants as direct observables in the ephemerides estimation and assesses the quality of the resulting solution. Methods. To this end, the apparent relative position between the two satellites is approximated by a second-order polynomial near the close encounter. This eventually leads to an expression for mutual approximations’ central instants as a function of the apparent relative position, velocity, and acceleration between the two satellites. Results. The resulting analytical expressions for the central instant partials were validated numerically. In addition, we ran a covariance analysis to compare the estimated solutions obtained with the two types of observables (central instants versus alternative observables), using the Galilean moons of Jupiter as a test case. Our analysis shows that alternative observables are almost equivalent to central instants in most cases. Accurate individual weighting of each alternative observable, accounting for the mutual approximation’s characteristics (which are automatically included in the central instants’ definition), is however crucial to obtain consistent solutions between the two observable types. Using central instants still yields a small improvement of 10–20% of the formal errors in the radial and normal directions (RSW frame), compared to the alternative observables’ solution. This improvement increases when mutual approximations with low impact parameters and large impact velocities are included in the estimation. Conclusions. Choosing between the two observables thus requires careful assessment, taking into account the characteristics of the available observations. Using central instants over alternative observables ensures that the state estimation fully benefits from the information encoded in mutual approximations, which might be necessary depending on the application of the ephemeris solution.

Full textAbstract:
Context. Convective motions in the solar atmosphere cause spectral lines to become asymmetric and shifted in wavelength. For photospheric lines, this differential Doppler shift varies from the solar disk center to the limb. Aims. Precise and comprehensive observations of the convective blueshift and its center-to-limb variation improve our understanding of the atmospheric hydrodynamics and ensuing line formation, and provide the basis to refine 3D models of the solar atmosphere. Methods. We performed systematical spectroscopic measurements of the convective blueshift of the quiet Sun with the Laser Absolute Reference Spectrograph (LARS) at the German Vacuum Tower Telescope. The spatial scanning of the solar disk covered 11 heliocentric positions each along four radial (meridional and equatorial) axes. The high-resolution spectra of 26 photospheric to chromospheric lines in the visible range were calibrated with a laser frequency comb to absolute wavelengths at the 1 m s−1 accuracy. Applying ephemeris and reference corrections, the bisector analysis provided line asymmetries and Doppler shifts with an uncertainty of only few m s−1. To allow for a comparison with other observations, we convolved the results to lower spectral resolutions. Results. All spectral line bisectors exhibit a systematic center-to-limb variation. Typically, a blueshifted “C”-shaped curve at disk center transforms into a less blueshifted “\”-shape toward the solar limb. The comparison of all lines reveals the systematic dependence of the convective blueshift on the line depth. The blueshift of the line minima describe a linear decrease with increasing line depths. The slope of the center-to-limb variation develops a reversal point at heliocentric positions between μ = 0.7 and 0.85, seen as the effect of horizontal granular flows in the mid photosphere. Line minima formed in the upper photosphere to chromosphere exhibit hardly any blueshift or even a slight redshift. Synthetic models yield considerable deviations from the observed center-to-limb variation. Conclusions. The obtained Doppler shifts of the quiet Sun can serve as an absolute reference for other observations, the relative calibration of Dopplergrams, and the necessary refinement of atmospheric models. Based on this, the development of high-precision models of stellar surface convection will advance the detection of (potentially habitable) exoplanets by radial velocity measurements.

Context. The star V426 Sge (HBHA 1704-05), originally classified as an emission-line object and a semi-regular variable, brightened at the beginning of August 2018, showing signatures of a symbiotic star outburst. Aims. We aim to confirm the nature of V426 Sge as a classical symbiotic star, determine the photometric ephemeris of the light minima, and suggest the path from its 1968 symbiotic nova outburst to the following 2018 Z And-type outburst. Methods. We re-constructed an historical light curve (LC) of V426 Sge from approximately the year 1900, and used original low- (R ∼ 500–1500; 330–880 nm) and high-resolution (R ∼ 11 000–34 000; 360–760 nm) spectroscopy complemented with Swift-XRT and UVOT, optical UBVRCIC and near-infrared JHKL photometry obtained during the 2018 outburst and the following quiescence. Results. The historical LC reveals no symbiotic-like activity from ∼1900 to 1967. In 1968, V426 Sge experienced a symbiotic nova outburst that ceased around 1990. From approximately 1972, a wave-like orbitally related variation with a period of 493.4 ± 0.7 days developed in the LC. This was interrupted by a Z And-type outburst from the beginning of August 2018 to the middle of February 2019. At the maximum of the 2018 outburst, the burning white dwarf (WD) increased its temperature to ≳2 × 105 K, generated a luminosity of ∼7 × 1037 (d/3.3 kpc)2 erg s−1 and blew a wind at the rate of ∼3 × 10−6 M⊙ yr−1. Our spectral energy distribution models from the current quiescent phase reveal that the donor is a normal M4-5 III giant characterised with Teff ∼ 3400 K, RG ∼ 106 (d/3.3 kpc) R⊙ and LG ∼ 1350 (d/3.3 kpc)2 L⊙ and the accretor is a low-mass ∼0.5 M⊙ WD. Conclusions. During the transition from the symbiotic nova outburst to the quiescent phase, a pronounced sinusoidal variation along the orbit develops in the LC of most symbiotic novae. The following eventual outburst is of Z And-type, when the accretion by the WD temporarily exceeds the upper limit of the stable burning. At this point the system becomes a classical symbiotic star.

This paper explores the critical role of persistent storage in containerized applications, with a focus on deploying and managing persistent storage solutions like Portworx. Drawing from over a decade of experience as a senior DevOps engineer, it delves into the practical aspects of ensuring data durability, availability, and performance in containerized environments. The paper aims to provide insights into the experiences gained from working with Portworx and other similar solutions, highlighting the challenges and advantages of implementing persistent storage in containers. The advent of containerization technologies has significantly streamlined the deployment and scaling of applications across various computing environments. Despite the benefits, managing stateful applications that require persistent data storage presents unique challenges in these ephemeral environments. This paper delves into the concept of persistent storage within containerized infrastructures, focusing on solutions like Portworx that facilitate the deployment and management of persistent storage across containerized applications. We explore the architecture, capabilities, and real-world application scenarios of such solutions, aiming to underscore their importance in modern cloud-native ecosystems.

Full textAbstract:
Abstract Basing on several cases, this paper develops a thought inspired by the content of the JOPE special issue on the educational value of monuments. It is a reflection about the locations which make the statues able to be transformed materially and semiotically, and which provoke discussion towards what is to be learnt by understanding the monument as a fragment and semiophore. I argue that the monument – located in a specific place which makes its contextual meaning - represents fragments, in Latin fractures or cracks, as expression of violence inflicted on an imaginary whole. Defining and accepting a monument as a fragment allows us to understand each change concerning it - including new location or relocation - as an incentive to learn about the meanings of new wholes and to consciously respond to them. On the one hand, it can effectively stop mimetic pressures to reproduce aggression towards monuments. On the other, it can create a ground for shaping an ethical attitude of co-responsibility for a common world that is not exclusively human. The strictly educational sense of the proposed redefinition of the monument would be to radicalize the sensitivity to its inherent feature, which is fragmentary nature, resulting in the fragility of the heritage it co-creates in the space of commonality. In the proposed understanding of the monument, apart from the emphasis on significant fragmentation, an important role is played by the decisive abandonment of the anthropocentric perspective. In the new perspective of the common world, the monument becomes an ephemeral heritage, and its most current educational value seems to lie there.

This article develops the concept of the “geometaphor” by considering the life and work of Loris Jacopo Bononi, poet-doctor-collector-inventor, through two elements of his landscapes: the castle of Castiglione del Terziere with its contents (a desire of eternity) and the fleeting seasons in the surrounding woods (the astonishment of the ephemeral). Two are the main lenses: Bononi’s relationship with his castle in Lunigiana and with specific objects preserved there (the contents of his bedroom and library, especially the incunabula collection); and his poetic production spanning the last years of his life, in the first decade of the XXI century. This is the first article that deals with Bononi’s poetic production in English.

Video games, while a digital art, live on physical media. Whether cartridge, magnetic tape or floppy disk, they degrade. Without care and study, they disappear and cannot be played again. While it might be possible to preserve play using emulation or video captures, scholars need to consider every option at their disposal to preserve video games for future study. This includes securing original versions of games and ephemera, recording play, interviewing game creators, and players, and much more. This article develops a new approach to conceptualise video games as material and cultural heritage, and proposes a methodology for their study, especially those for which there is no original version left.

Full textAbstract:
Abstract This article considers three moments from the beginning, middle and end of Derek Jarman’s artistic career: Lindsay Kemp’s opening dance in Sebastiane (1976), Jarman’s words on a performance by Michael Clark in the 1980s, and Jarman’s last film Blue (1993), while holding onto the affective registers of his final diary entry (1994). Considering the ways in which Jarman indexed the ephemeral myth-making processes of queer life and art, the author develops a new kinetic-temporal methodology for exploring reception based on the fleeting queer modalities of dance. As such this article makes a series of important connections between classical reception studies, queer theory, critical theory, and dance studies. It argues that, despite the fleeting, erotic, and partial engagements with the past offered by Jarman — which challenges ideas of fixity or lineage — an identification nevertheless emerges with the hierarchies of white supremacist Imperialism.

Full textAbstract:
Neighbourhood places like shops, cafes and parks support a variety of social interactions ranging from the ephemeral to the intimate. Repeated interactions at neighbourhood places over time lay the foundation for the development of social cohesion and collective efficacy. In this study, we examine the proposition that changes in the presence or arrangement of neighbourhood places can destabilise social cohesion and collective efficacy, which has implications for crime. Using spatially integrated crime, social survey and parcel-level land-use classification data, we estimate mixed effects panel models predicting changes in theft and nuisance crimes across 147 Australian neighbourhoods. The findings are consistent with neighbourhood social control and crime opportunity theories. Neighbourhood development – indicated by fewer vacant properties and fewer industrial and agricultural sites – is associated with higher collective efficacy and less crime over time. Conversely, introducing more restaurants, transit stations and cinemas is associated with higher theft and nuisance over time regardless of neighbourhood collective efficacy. We argue that the addition of socially conducive places can leave neighbourhoods vulnerable to crime until new patterns of sociability emerge and collective efficacy develops.

Full textAbstract:
Abstract The paper develops a conceptual framework for the analysis of crises. It rests on the central argument that crises cannot be restricted to exceptional occurrences or temporarily delimited events, but we approach crisis as ontologically constitutive for our everyday lives. The concept of “discursive dislocation” is the cornerstone of this endeavor, as it grasps multiple aspects of sociopolitical instability, including societal deficiencies, fragilities, and political failures. Through theoretically advancing the concept of dislocation, we systematize three dimensions of crisis as permanent, recurring, and ephemeral dislocation. This allows us to analyze crises not only in their immediate environment but also makes it possible to understand them in their broader sociopolitical context. The conceptual framework is illustrated with the example of the COVID-19 pandemic in the United States, which reveals how the construction of the pandemic as a crisis is embedded in the historically ingrained self-portrayal of the United States, and how crisis responses are invoked to serve particular sociopolitical purposes in retaining an established American identity.

Full textAbstract:
This study assesses potentially sensitive effects of a specific sub-class of digital social technologies called social broadcasting networks (SBNs). Adopting the explanatory mechanisms of social network structures (Borgatti et al. 2009; Kane et al. 2014), and adapting Herzberg et al’s (1959) Two Factor theory, it investigates how the structure of a SBN (conceptualized as its relative advantage), and the influence of users in a SBN empower two key news consumption behaviours viz. switching and continuance. Employing the survey (qualitative) method, the study empirically validates the news consumption behaviours of 325 respondents. Findings reveal a more nuanced role of SBNs indicating the potential benefits to news firms because of individuals switching to traditional news mediums while in the same breadth highlights the potential of SBNs as competitive news providers. It shows intermittent use of SBNs and signifies that when online and offline news mediums co-exist, influence of users in the incumbent (online) medium plays a powerful role in inducing or refraining the use of a substitute offline medium. This study develops new ontological and theoretical understanding of the entanglement of technology and social activity that is dynamic, at times ephemeral and pervasively ubiquitous.

Full textAbstract:
Abstract Surging and streaming of glaciers are modulated by meltwater availability and pressure which controls mechanical coupling at their beds. Using laboratory-scale experimental modelling and palaeoglaciological mapping, we explore how subglacial drainage landsystems control meltwater drainage efficiency and ice flow velocities for terrestrial-based ice lobes resting on flat horizontal and permeable beds. Two end-members regimes, surging and streaming, appear in our experiments. The surge regime is characterised by a rapid increase of drainage efficiency through development of tunnel valleys and their tributaries, thus reducing the duration of ice flow speed-up events by lowering water pressures and increasing ice-bed coupling. Tunnel valleys connected to ice lobe margins, submarginal thrust moraines, reduced ice lobe extensions and ephemeral shear margins are the most distinctive characteristics of this regime. The stream regime is characterised by disconnected channels of smaller dimensions unable to evacuate all the meltwater: this prolonged drainage inefficiency leads to sustained high ice flow velocity and steady shear margins. Small and rectilinear meltwater channels devoid of tributaries, often disconnected from ice lobe margins, and lineation swarms are diagnostic of this regime.

Kumbh Mela is held once in twelve years in India and is being hailed as largest congregation on earth. Kumbh Mela held in Allahabad in 2013 provided unprecedented learning opportunity and seminal scholarship for multi-disciplines spanning public health, business, religious expression, temporary infrastructure, and the makeshift economy among other subjects. Harvard university book 'Kumbh Mela - Mapping the Ephemeral Megacity', claims that Maha Kumbh Mela held in 2013 was better organized than FIFA world cup held in Brazil in 2014. This bears a testimony to the 'Globalizing Indian management thought'. The sheer size is indicated by the fact that as an estimate 120 million people visited the Kumbh Mela at Allahabad in 2013. These events made multinational and Indian companies to mull over sacred calendars and promote their wares and services. There were innovate sales promotions such as 'Lifebuoy se haath dhoye kya' to 'Kya apne dant snan kiya' by Dabur among others. Kumbh Melas as an event represents harmonious existence of religious beliefs and business. This also provides unique opportunity for the Marketers to contribute to the society for social responsibility, while demanding business leadership and cultural sensitivity from managers.The research article makes modest attempt to elucidate various sales promotions of select brands in the context of Kumbh Mela as religious events, and develops conceptual frameworks for understanding of sales promotions at religious events in India for the marketers.

Full textAbstract:
This theoretical paper develops “The Impulse Engine Framework” to analyse Generation Z’s impulsive buying of electronics in online marketplaces. Integrating the Stimulus-Organism-Response (S-O-R) paradigm with dual-process theory, the paper reveals how digital platforms engineer impulse behaviours through three synergistic mechanisms: Cognitive short-circuiting via frictionless interfaces (e.g., one-click checkout reduces deliberation by 68%) and neuroscientific tuned stimuli (scarcity popups trigger amygdala responses 200ms faster in Gen Z brains); Identity capitalism transforming electronics into social tokens (e.g., AirPods as status markers), amplified by influencer-driven tribal belonging; Asymmetric neuro-marketing creating dopaminergic loops (personalized nudges → impulse purchase → guilt → renewed browsing). The key findings indicate Gen Z’s neurobiological susceptibility (300% stronger nucleus accumbent activation during impulse purchases), psychological vulnerabilities (smartphone addiction depletes prefrontal activity by 17%; 8.3× higher BNPL debt penetration with low financial literacy), and platform exploitation of these traits (short-form video commerce drives 71% of Southeast Asia’s impulse market). We conclude this ecosystem constitutes a zero-sum game: Gen Z trades financial well-being for ephemeral social capital while platforms monetize cognitive biases. The paper advances theory by identifying dual arousal/pleasure mediation pathways and proposes stakeholder-specific solutions: • Platforms: Ethical friction (e.g., cooling-off periods) • Policymakers: BNPL debt ceilings (max 15% income) • Consumers: Digital hygiene protocols • Researchers: Neuroethics guidelines for metaverse commerce.

The French pill scare is usually presented as a “media debate” triggered by the case of Marion Larat, a young woman who suffered a stroke attributed to the pill she was taking. This article intends to focus on a practice that preceded, accompanied, and followed this health scare: the publication of online testimonies of thrombotic reactions posted on the website of the French Association of Victims of Pulmonary Embolism and Stroke Associated with Hormonal Contraception (Avep). Through a discourse analysis, we intend to analyze these online public self-reports as an activist practice aimed at criticizing the dominant medical discourse on contraception. Four discursive frames emerged: unpreparedness of women and doctors, denial of blame and search for the cause, breaking the silence and building solidarity, and collective action. The first two frames concern the process women put in place to obtain the right to speak about and criticize a medical practice. The right to speak is achieved through a concise narrative style focusing on facts, bodily manifestations, and risk factors. The second pair refers to the formation of pill victims as subjects with an ambivalent status and ephemeral agency. The testimonies build what we call “lone solidarity”, that is, the creation of a social bond and action around a common experience of witnessing medical injustice that develops without any exchange between members. This proves to be inclusive and viral, but at the same time fiercely anti-representational with respect to political struggles or social identification.

AbstractUnderstanding flower developmental processes is a prerequisite for improving flowering ‘plants’ production. Adonis amurensis is a fascinating spring ephemeral plant that develops its flower organs underground. Nevertheless, knowledge of the molecular mechanisms driving this particular process is scarce. Herein, we examined transcriptional changes during underground flower differentiation in A. amurensis and unveiled key differently regulated genes and pathways. High-throughput RNA sequencing of meristems at different flower developmental stages, including flower primordium (FP), sepal stage (SE), perianth primordium (PE), stamen stage (ST), and pistil stage (PI), identified 303,234 unigenes that showed 44.79% similarity with sequences in Aquilegia coerulea. Correlations, principal component, and differentially expressed genes (DEGs) analyses revealed that few molecular changes occurred during the transition from PE to ST. Many DEGs exhibited stage-specific regulations. Transcription factor (TF) and phytohormone family genes are critical regulators of the floral differentiation process in A. amurensis. The most differentially regulated TFs were MADS, FAR1, MYBs, AP2/ERF, B3, C2H2, and LOBs. We filtered out 186 candidate genes for future functional studies, including 18 flowering/circadian-related, 32 phytohormone-related, and TF family genes. Our findings deepen our understanding of the underground flower differentiation process and offer critical resources to dissect its regulatory network in A. amurensis. These findings establish a foundational platform for researchers dedicated to exploring the unique phenotypic characteristics of this specific flowering modality and delving into the intricate molecular mechanisms underpinning its regulation and expression.

Full textAbstract:
Furukawa Hideo's novel-length Umatachi yo, sore demo hikari wa muku de (Horses, Horses, In the Innocence of Light) is compelling and important for all the reasons that it can be exasperating and demanding. It is driven by the triple disasters of 3.11-the earthquake, tsunami, and then nuclear meltdown in northeast Japan, of March 11, 2011. Horses, Horses first appeared in the journal Shinchō in July 2011 and in book form shortly thereafter; it captures the shock and disorientation of that time. It is many things, but it is primarily a 3.11 document. It is hard to overstate the effect of 3.11 in Japanese society; its resonances to 9/11 are multilayered: it is a Japanese disaster and also a world event; many, many things are now measured as “before” or “after;” it is a semiotic event comprised of endless, horrific, film loops and digital images. In that context, Horses, Horses has become one of the most important touchstones for the disasters: raw, sometimes confused, multilayered, overwhelmed and overwhelming, forceful, personal; just like, that is, the disasters and the responses of those caught up by it. It captures the sense that all the important things of a day before-all the major novels to be written, for example-were suddenly meaningless, ephemeral, and, somehow, devoid of life. And each aftershock is a reminder; as this narrator relates, with each new jolt manuscript pages are destined for the trash.

Full textAbstract:
Readers will probably understand from written instructions that the task of preparing lithography stones can be slow and physically demanding. A detail in the recently updated Tamarind Techniques for Fine Art Lithography also worth noting is that ‘careful attention is needed for this and all other aspects of lithography’ (Devons, Hammon, and Lagutta 2008, p.126). Reflecting on the significance of this sometimes lengthy process, my tentative proposal is that, if understood as a form of contemplative labour, limestone graining may offer a way to think about the quality of the ‘careful attention’ needed for lithography. However, far from a silent meditative activity, graining stones is also noisy. Likewise, in this account attention and noise are equally present as the indivisible aspects of a mode of perceptual awareness that I propose is familiar to lithographers. This paradoxical coupling, I suggest, might also reveal the nature of the language engendered by the synchronic vibrations between inscribing flesh and limestone matrices. A fragment from ongoing research that tests the generative intersection between stone lithography and language, infiltrating the seemingly mute pixels of the text that follows, is the sensory phenomenon of sound: both as the protagonist for an interdisciplinary narrative that brings lithography into dialogue with a tour of the world’s sonorous stones and in a rhetorical method of disparate parts that invites the reader to experience an equivalence between listening carefully to the ephemeral, and attending closely to the particular. Alongside geologists, musicians, and acoustic engineers, shaping the terrain of this speculative coupling of lithographic and lithophonic worlds are the voices of Simone Weil, Cynthia Bourgeault, Ashon Crawley, Cecile Malaspina, Michel Serres, Salome Voegelin, and the life and work of Birgit Skiold.

Evelyn Fox Keller calls the form of organisms a “devious” problem. How and why do such forms arise? Models, Keller argues, are necessary inroads to these questions. The speculative-propositional mode of computational and mathematical models permits scientists to question the physical and mental processes that shape matter into elegant form despite the “void” of certainty opened by the complexity of vitality. This article documents the use of the LOGO programming language in model-mind making as well as in experimental coding pedagogies for special needs students circa 1968. It provides a historical and philosophical background for interpreting clinical observations of two young autistic students, David and Joey. The article demonstrates that the designers of LOGO understood their design choices in terms of philosophical debates about the nature of purposive orientations in organisms. The author argues that cautious engagement with those debates—guided by Keller’s philosophy of models and Catherine Malabou’s understanding of Immanuel Kant’s concept of schema—can open for humanists an interpretive project aimed at elucidating the historical meaning of the graphical user interface. Insights into the aesthetics of resistance from autistic rhetorician Remi Yergeau and philosopher-poet Fred Moten allow neuroqueer ephemera, lingering in the archives of LOGO, to illuminate a politicization of mental variety nascent in digital screens.

On 3 October 2020, a 22 years young man, Joshua Ambrose, was shot dead by a team of the Nigerian Police Special Anti-Robbery Squad (SARS) in Delta State, Nigeria, on the allegation that he was an Internet fraudster (Dambo et al., 2021). The SARS was established in 1992 to curb crimes. However, the SARS has been accused of gross humanrights violations (Wada, 2021). Joshua's shooting was captured in a video. The audio in the video states that the Police just shot and killed the owner of a Lexus SUV and zoomed off with his car (Agbo, 2021). In a few days, the viral video generated outrage that transformed into vast decentralised street protests in major cities in Nigeria, mainly organised through social media. EndSARS Movement continues to construct memories across time, an area dominated by Western studies (Daphi & Zamponi, 2019). Researchers (Nwakanma, 2022; Dambo et al., 2021; Nwabunnia, 2021; Ajaegbu et al., 2022) have explored the EndSARS Movement from diverse perspectives. Nonetheless, the literature is devoid of studies from the memory study perspective, a critical area in social movement studies (Smit, 2020; Merill & Lindgren, 2020). Besides, considering the online feature of the Movement, the current literature on EndSARS needs to include the novelty and methodological rigour of virtual ethnography. Consequently, this study attempts to understand how protesters use Facebook, WhatsApp, and Instagram Stories (Ephemeral; 24 hours $2 ) to construct a memory of the EndSARS Movement in Nigeria from 2020 until its Anniversaries in 2021, 2022, and 2023.

Full textAbstract:
Source-to-sink studies commonly assume independent sediment routing systems for siliciclastics and carbonates. This study integrates satellite-derived topography, imagery, swath multibeam bathymetry, and field observations to characterize a mixed carbonate-siliciclastic routing system from source to sink in the Gulf of Aqaba, northern Red Sea. The study area is lined by ephemeral desert streams (wadis) that deliver pulses of sediment to the shelf and basin during flash floods. We find that where wadis are distributary at the coast, they deposit amalgamated fan deltas associated with a continuous fringing reef, a narrow continental shelf, and a smooth line-fed slope system devoid of major submarine canyons or fans. Where knickpoints have migrated to the shoreline or into active wadi channels, the fringing reef is bisected by reentrants (sharms), there is no continental shelf, and the slope is composed of a rugged assortment of canyons and ridges. Development of sharms is the net effect of erosion by headward knickpoint migration and construction by differential aggradation on the shelf. Submarine fans linked to shelf-incising canyons are generally larger than those associated with slope-confined canyons. Fan size strongly correlates with the catchment area of the affiliated wadi networks, linking terrigenous and marine sedimentary systems. Our study offers a window into coupled terrigenous, coastal, shelf, slope, and basinal processes that have produced a steep, narrow, mixed carbonate-siliciclastic margin. The findings presented herein build on traditional depositional models and demonstrate feedbacks between integrated carbonate and siliciclastic sediment routing systems, especially in an arid climate.

Full textAbstract:
AbstractAnimal foraging strategies are formulated in a complex decision‐making matrix that is predicated on balancing energy intake and expenditure within a landscape of predation risk. Game species encounter dynamic risks during hunting season as ephemeral predators (i.e., hunters) alter the predation risk landscape daily and seasonally. Predators and prey often concentrate around food sources during hunting season, further complicating the balance of energy intake and risk minimization for prey species. For example, many wetland managers provide energy‐rich food resources, such as unharvested grain, that attract waterfowl. Hunter access to these areas varies and alters the inherent risk that wintering waterfowl face to use these resources. We hypothesized use and subsequent depletion of unharvested flooded corn fields would be influenced by proximate anthropogenic disturbance and predation risk, shifting the bioenergetic landscape for waterfowl. We first sampled 145 unharvested flooded cornfields under different hunting access regimes to estimate corn biomass in October 2019 and 2020 in western Tennessee, USA. We then returned to 30 of those fields biweekly during fall‐winter 2019–2021 to estimate depletion rates in 60 fields. We modeled depletion rate as a function of hunting risk and forage accessibility by including the variables of corn ear height above water surface, field size, field ownership type, and field distance from sanctuary in our statistical model. Biomass estimates derived from initial surveys indicated private fields that were hunted provided the greatest corn biomass (7,134 ± 448 kg/ha), followed by public fields that were hunted (5,272 ± 320 kg/ha) and finally sanctuaries closed to hunting (3,995 ± 371 kg/ha). Corn biomass was depleted 2–4 times faster on sanctuaries than on hunted fields during November and December but 2 times faster in hunted fields than in sanctuary fields in January. Depletion rates increased as surface water came closer to corn ears but were unaffected by field size or field distance from unhunted sanctuary. Sanctuary fields were devoid of corn by the end of January, whereas 55% of public and 50% of private hunted fields still had corn remaining on 15 March, by which time most ducks had likely initiated migration. Private lands sampled in 2020 contributed nearly 7 times more energy than assumed in the 2015 Lower Mississippi Alluvial Valley Joint Venture energetic allocation models. Despite being devoid of hunters at night, hunted lands are not perceived by foraging waterfowl to be nocturnally similar to sanctuary areas during hunting season. In turn, hunted fields were exploited by ducks later in the season when sanctuary resources were scarce, providing available biomass for migrating birds. It may be important for managers to retain water on hunted fields through early spring given the lack of energy‐dense foraging resources available on sanctuary areas. Conservation planners should consider resource depletion as a multiplicative function of hunting risk and abundance when allocating foraging habitat objectives for waterfowl in the non‐breeding season.
