Limits and CO2equilibration of near-coast alkalinity enhancement
Authors: He Jing , Tyka Michael D. 
Published: January 2023

Abstract. Ocean alkalinity enhancement (OAE) has recently gained attention as a potential method for carbon dioxide removal (CDR) at gigatonne (Gt) scale, with near-coast OAE operations being economically favorable due to proximity to mineral and energy sources. In this paper we study critical questions which determine the scale and viability of OAE. Which coastal locations are able to sustain a large flux of alkalinity at minimal pH and ΩArag (aragonite saturation) changes? What is the interference distance between adjacent OAE projects? How much CO2 is absorbed per unit of alkalinity added? How quickly does the induced CO2 deficiency equilibrate with the atmosphere? Choosing relatively conservative constraints on ΔpH or ΔOmega, we examine the limits of OAE using the ECCO LLC270 (0.3∘) global circulation model. We find that the sustainable OAE rate varies over 1–2 orders of magnitude between different coasts and exhibits complex patterns and non-local dependencies which vary from region to region. In general, OAE in areas of strong coastal currents enables the largest fluxes and depending on the direction of these currents, neighboring OAE sites can exhibit dependencies as far as 400 km or more. At these steady state fluxes most regional stretches of coastline are able to accommodate on the order of 10s to 100s of megatonnes of negative emissions within 300 km of the coast. We conclude that near-coastal OAE has the potential to scale globally to several Gt CO2 yr−1 of drawdown with conservative pH constraints, if the effort is spread over the majority of available coastlines. Depending on the location, we find a diverse set of equilibration kinetics, determined by the interplay of gas exchange and surface residence time. Most locations reach an uptake efficiency plateau of 0.6–0.8 mol CO2 per mol of alkalinity after 3–4 years, after which there is only slow additional CO2 uptake. Regions of significant downwelling (e.g., around Iceland) should be avoided by OAE deployments, as in such locations up to half of the CDR potential of OAE can be lost to bottom waters. The most ideal locations, reaching a molar uptake ratio of around 0.8, include North Madagascar, California, Brazil, Peru and locations close to the Southern Ocean such as Tasmania, Kerguelen and Patagonia, where the gas exchange appears to occur faster than the surface residence time. However, some locations (e.g., Hawaii) take significantly longer to equilibrate (up to 8–10 years) but can still eventually achieve high uptake ratios.

Published: January 2023

Abstract. This paper presents version 1.0 of the World Atlas of
Last Interglacial Shorelines (WALIS), a global database of sea-level proxies
and samples dated to marine isotope stage 5 (∼ 80 to 130 ka).
The database includes a series of datasets compiled in the framework of a
special issue published in this journal (https://essd.copernicus.org/articles/special_issue1055.html, last access: 15 December 2022). This paper collates the individual contributions (archived
in a Zenodo community at https://zenodo.org/communities/walis_database/, last access: 15 December 2022) into an
open-access, standalone database (Rovere et al., 2022,
https://doi.org/10.5281/zenodo.7348242). The release of WALIS 1.0 includes
complete documentation and scripts to download, analyze, and visualize the
data (https://alerovere.github.io/WALIS/, last access: 15 December 2022). The database
contains 4545 sea-level proxies (e.g., marine terraces or fossil beach
deposits), 4110 dated samples (e.g., corals dated with U-series), and 280
other time constraints (e.g., biostratigraphic constraints or tephra
layers) interconnected with several tables containing accessory data and
metadata. By creating a centralized database of sea-level proxy data for the
Last Interglacial, the WALIS database will be a valuable resource to the
broader paleoclimate community to facilitate data–model integration and
intercomparisons, assessments of sea-level reconstructions between different
studies and different regions, as well as comparisons between past sea-level
history and other paleoclimate proxy data.

English Competencies and Challenges for Data Science and Cyber Security Students at Al Istiqlal University
Authors: Khaled M Masood  
Published: January 2023

This present research aims to determine the growing needs and challenges faced by Data Science and Cyber Security students at Al Istiqlal University's Faculty of Information Technology when learning the English language. It also tries to ascertain whether gender and level of competence affected their requirements and difficulties in mastering the English language. 35 cadets who are specializing in Data Science and Cyber Security make up the sample. The researcher gave out 39 questionnaire items divided into eight domains. The results show that cadets in Data Science and Cyber Security did not undergo any guidance regarding how to utilize English in the discipline while engaging in the analysis of data or cyber security keywords. Additionally, the study demonstrates that cadets majoring in data science and cyber security did not receive any guidance on how to learn to communicate in English, and the teaching activities in the English programs they had taken did not match their notions of the standards for expert English. Moreover, English proficiency requirements for cadets enrolling in Data Science and Cyber Security courses should be taken into consideration. Additionally, no statically meaningful differences in the demands for key competencies and barriers faced by Data Science and Cyber Security cadets are found when gender and competency traits are taken into consideration.
Decoding Walter Morel- Class Politics in Sons and Lovers
Authors: Avantika Chamoli  
Published: January 2023

David Herbert Lawrence’s Sons and Lovers (1913) tells the story of the Morels— a working-class family. Lawrence has referred to Sons and Lovers as his ‘colliery novel’. The present paper attempts to decode the class politics of the novel by closely focussing on Walter Morel, the chief working-class figure in the novel. The novel’s narrative pivots around the domestic concerns of the Morel family, very often in which, Walter Morel, emerges as a villain and an oppressor of his wife and children. The text poignantly portrays domestic discord and the hardships that Gertrude Morel and her children face. However, it fails to delve into or elucidate upon the underlying reasons for the emergence of these hardships in the first place. At the obvious level, Walter Morel seems to be demonised as a brute who causes his family continuous pain. However, it is imperative that the text is read within the larger social, economic, and political structures of its time, which significantly shaped and influenced the lives and action of Walter Morel and his family. This paper attempts to recuperate dispersed evidence from the margins of the novel to gainsay a superficial interpretation of Walter Morel as a mindless violent brute who is solely responsible for the trials and tribulations of the Morel family. It attempts to connect the dots between the representation of Walter Morel with the narrative’s inclination towards the middle-class value system aspired to by the other members of his family, in order to, gain a more nuanced insight into the class politics of the novel.
Diasporic Hybridity and Liminality in Jhumpa Lahiri’s The Lowland
Authors: Yogesh Kumar  , Prof. Gunjan Sushil  
Published: January 2023

Diasporic experiences of Indian characters have drawn a considerable attention of social thinkers, political leaders, literary scholars and critics. The experiences of immigrants have been explored by postmodern researchers and writers in an effort to understand the reasons behind their hopelessness, the breakdown of their families, and how they ultimately internalise the ideals of the host culture at the urging of the native culture. Greek word for dispersal is where the word “diaspora” originates. It speaks of the scattering and displacing of individuals from their place of origin. The authors of diaspora have tried to underpin the hidden underlying reasons of leaving one’s country and compensating for their periferal status in the adopted culture. While juxtaposing the past and present experiences, the diaspora writers critically analyise the nature of exile, homelessness, nostalgia, memory of native land, hybridity, liminality, marginality, culture shock and identity crisis. In this research article, Jhumpa Lahiri's representation of immigrants’ struggles with identity, self-formation, and cultural differences in her book The Lowland will be critically assessed. It attempts to throw light on the social and political insecurities, human rights and cultural challenges brought forth by their liminal status. Facing liminality the characters are hovering in a perpetual mental dilemma between Indian lifestyle and American advanced culture. The major themes of the novel are location, relocation, dislocation, displacement and alienation which are solely caused by characters’ personal choices and actions.

Published: January 2023

El propósito de este estudio es la comprensión de la experiencia educativa del Liceo
Camino de Luz de Puente Alto, institución que trabaja en contexto de encierro
carcelario. En esta perspectiva indagamos sobre 1) la formación contextual en la que
está colocado el liceo y por las reglas que lo articulan; 2) el dinamismo propio de este
establecimiento y su funcionalidad; 3) la praxis instituyente de profesoras y profesores
en la gestión de la comunidad educativa; 4) su incidencia en los procesos de cambio de
las personas recluidas. Se concluye hipotéticamente que el liceo Camino de Luz está
inserto en una formación contextual compleja compuesta por diversos contextos con
reglas del juego muy distintas e incluso opuestas. El contexto dominante es el de
Gendarmería. Otro contexto relevante es la comunidad carcelaria, espacio de vida de
las personas privadas de libertad. El contexto socioeducativo construido por los
profesores (es) ofrece a las personas recluidas un sistema de posibilidades para
desarrollarse como personas y proyectar procesos de reinserción, desistimiento e
inclusión sociocomunitaria. Asociado a ello, esta comunidad educativa sitúa a los
profesores(as) como gestores del conocimiento, gestores de vínculos, gestores
comunitarios, gestores del cuidado y gestores de cambio.

The Sukari Gold Deposit, Egypt: Geochemical and Geochronological Constraints on the Ore Genesis and Implications for Regional Exploration

Published: January 2023

AbstractThe Sukari gold deposit (&gt;15 Moz Au) in the Eastern Desert of Egypt is hosted by a deformed granitoid stock (Sukari tonalite-trondhjemite intrusion) and mainly occurs as a network of crosscutting sulfide-bearing quartz (± carbonate) veins and intensely sulfidized-silicified-sericitized wall rock. Emplacement of the Sukari intrusion into a tectonized Neoproterozoic accretionary complex was controlled by a system of NE- to NNE-trending oblique faults that are related to a deep-seated positive flower structure. A robust genetic model has been hampered by the poorly understood relationships between gold mineralization and host rocks. In this study, zircon U-Pb ages of three samples from the Sukari intrusion define a crystallization age of ~695 ± 2 Ma. In contrast, hydrothermal sericite from the ore zone yields an 40Ar/39Ar age of ~625 ± 3 Ma, which coincides with the onset of major sinistral transpression in the region.Features including sigmoidal morphology of gold quartz veins and abundant subhorizontal tension gashes alongside widespread brecciation and recrystallization suggest that quartz veining occurred during renewed shortening and exhumation through the brittle-ductile transition. Petrographic and micro-X-ray fluorescence (µXRF) studies indicate that disseminated gold and sulfides, commonly associated with sericite and carbonate alteration, are mostly confined to stylolitic bands in the quartz veins. Oscillatory and sector zoning patterns, irregular As-rich bands, and truncations between early- and late-genetic pyrites reflect variations in temperature and mechanism of ore deposition, demonstrated by variable As/S and Co/Ni ratios in the different pyrite generations. Laser ablation-inductively coupled plasma-mass spectrometry analysis pinpoints the covariance of gold and arsenic contents in pyrite, but free milling gold inclusions in microfractures consistently have a mercury-bearing electrum composition, depicting different ore formation stages.Ore fluids with δ34SH2s values of –1.9 to –3.0‰, modeled from gold-associated pyrite and arsenopyrite assemblages with nearly identical δ34S values, suggest a likely single source of sulfur. Alternatively, multisourced sulfur could have extensively mixed and equilibrated by fluid reaction with carbonaceous wall rock. Gold deposition was triggered by abrupt changes in fluid pH and fO2. As an implication for future exploration, sites of maximized strain gradients adjacent to granitoid bodies along extensive transpression zones in the district could be highly prospective targets, particularly where imprinted by sericite-carbonate ± graphite alteration.
Determinants of Girls’ Educational Performances in Science, Technology, Engineering, and Mathematics (STEM) Subjects across Selected Schools in Oromia Regional State, Ethiopia
Authors: Kufi Endalew Fufa 
Published: January 2023

The purpose of this research was to investigate key determinants of girl’s performances in STEM subjects in selected schools of Oromia Regional State, Ethiopia. Interpretive explication method was employed in which interview and focus-group discussion were instruments of data collection. Participants’ interview and focus-group data were carefully collected based on which due transcription was made. In the transcription process, careful selection was made on issues that related to basic research questions. Then, coded categories were formed under each team to analyze the data. The findings indicated that, while girls outsmarted boys in almost all natural science and mathematics subjects, there were gaps among female students themselves owing to low economic standards to cover the costs of living and learning, negative peer-pressure, and shortage in schools to scale up intra-group support among female students. In spite of the existence of some outsmarting girls in schools who were able to perform much more than males, there also existed socio-economic determinants which created barriers on average achieving girls’ performances. There were also digital divides among girls from providing and less-providing homes from the point of view of facilities.
