Hate Speech Detection Using NLP and Machine Learning
Authors: Boothati Sasanka , M Prof. Humera Khanam , Khudhus MD. A.
Published: March 2024

Abstract: The use of social media has been growing in an eccentric fashion making it a medium for sharing opinions, ideas, and thoughts of an individual with others. This has made things complex with what is considered a genuine comment or rather a hypocritic deliberative nuance to damage or incite hatred on an individual or a group belonging to a community, race, gender, nationality, etc, In this paper, the detection of hate speech with the use of sentiment polarity scores and the Term Frequency Inverse Document Frequency(TFIDF) scores with machine learning algorithms is to decrease the true negatives and false positives by the use of Natural Language Processing. The Machine Learning algorithms used are Logistic Regression and Random Forest Classifier. The phases of NLP are done to preprocess the tweets that are available on the Kaggle with about 25 thousand tweets from the social media giant “Twitter”. The processed tweets are then with the use of two ML Algorithms trained for vaderSentiment polarity scores and TFIDF scores from which metrics are obtained. The results of sentiment polarity scores(7 points) are less accurate in the detection of hate speech as compared to TFIDF scores(8 points).

Entanglement Trajectory and its Boundary
Authors: Lin Ruge
Published: March 2024

In this article, we present a novel approach to investigating entanglement in the context of quantum computing. Our methodology involves analyzing reduced density matrices at different stages of a quantum algorithm's execution and representing the dominant eigenvalue and von Neumann entropy on a graph, creating an "entanglement trajectory." To establish the trajectory's boundaries, we employ random matrix theory. Through the examination of examples such as quantum adiabatic computation, the Grover algorithm, and the Shor algorithm, we demonstrate that the entanglement trajectory remains within the established boundaries, exhibiting unique characteristics for each example. Moreover, we show that these boundaries and features can be extended to trajectories defined by alternative entropy measures. The entanglement trajectory serves as an invariant property of a quantum system, maintaining consistency across varying situations and definitions of entanglement. Numerical simulations accompanying this research are available via open access.
Feminismo e capitalismo: um rompimento necessário
Authors: Rodrigues Roberta da Cunha
Published: March 2024

Os movimentos de mulheres que endossam uma economia liberal e são cooptados pelo capitalismo demonstraram serem insuficientes e problemáticos, pois não alcançam as raízes das opressões e alimentam um modo de produção que precisa das mais variadas violências para se manter em equilíbrio. É possível visualizar essa insuficiência a partir da obra de Betty Friedan (uma das representantes do feminismo liberal nos Estados Unidos da década de 1960), que trata a subordinação feminina como uma questão autônoma, desvinculada das outras opressões mantidas e acentuadas pelo modo de produção capitalista. Para compreender esse problema e superá-lo, será necessário explorar a teoria do valor de Karl Marx e, partindo de autoras como Silvia Federici, Angela Davis, Heleieth Saffioti e Ana Montenegro, entender como o capitalismo se utiliza de desigualdades já existentes em sociedades pré-capitalistas para solidificar marcas sociais que permitam uma maior exploração. É nesse sentido que surge a importância de analisar o que há por trás das opressões sofridas pelas mulheres, entendendo que o feminismo não pode ser compreendido como um movimento político autônomo que busca somente a libertação da mulher a partir da busca pela própria identidade, como propõe Friedan. Essa perspectiva transforma um debate político-econômico (que deve ser posto de maneira coletiva e considerando uma ruptura no atual modo de produção) numa discussão sobre empoderamento individual. Isso não significa que esse aspecto não seja relevante, mas sim que ele é insuficiente para realizar uma análise completa e profunda sobre as questões feministas.

Genre Typology of Drama in European and Sanskrit Literature
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Lidova Natalia R.
Published: March 2024

The article examines the notion of drama as a genre category in European and ancient Indian theatrical theory. The analysis of ancient texts, foremost the treatise of the Nāṭyaśāstra, which can be considered the most authoritative primary source for the study of classical Indian poetics, forms the basis of the research. This paper identifies Sanskrit analogues of such fundamental concepts of Western literary theory as “drama,” “genre,” “performance,” “scenicism,” “literariness,” etc. The closest analogical to European definitions of drama and genre Sanskrit notions are investigated in depth. They are primarely nāṭya and prayoga — two terms used to define various performative aspects of the play. Another notion studied in the paper is rūpa, which originally stood for “scenario” and, later on, for textual and literary format of the staged play. Due to its universality, the same term functioned as the general definition of ten “exemplary” spectacular forms. Finally, the category of vṛtti is discussed, employed in the Nāṭyaśāstra for the characterization of stylistic features of early mysterial performances and, later on, of classical Sanskrit plays. The scope of the paper does not limit itself to bringing to light and discussing these various notions. The ultimate goal is to highlight the differences between Eastern and Western poetological systems and to point out fundamental issues arising from the non-critical use of European terminology when interpreting and investigating ancient Indian aesthetics.

Published: March 2024

Each national literature is a part of national history. It presents the features of the national culture and the people who live and develop in specific cultural and traditional conditions. Each nation has its unique genius that sings the national beauty. Armenian ashug Sayat’-Nova’s creativity has had a significant influence on Armenian literature. Sayat’-Nova, as a national poet, had created poetry with its genre subdivisions. We can consider such categories as spiritual, patriotic poetry, glamorous social poetry, and folk-gusan songs. The present research has been carried out along the lines of Sayat’-Nova’s verbal creativity through the interpretive prism of theorists and literary critics with special reference to Valeri Brusov, who highlighted the exclusive richness of Sayat’-Nova’s artistic devices, the peculiar features of his literary genre, style, and language. The article focused on the relevance of Russian-Armenian literary relations, which became particularly crucial with the publication of Valeri Brusov’s anthology “Poetry of Armenia” in 1916. The outstanding Russian writer, critic, and translator has highly appreciated the exceptional richness of Armenian literature and interpreted each piece of verbal creativity with great accuracy. His opinion is that Sayat’-Nova name deserves to be a part of world literature. Armenian ashug has to stand next to the honored names and glorified works of Western literature.
Dual Faith of Evgeny Ivanov: To the Study of the Role of Vera F. Komissarzhevskaya in the History of Symbolist Life Creating
Authors:   Institute of Russian Literature (Pushkin House) of the Russian Academy of Sciences, Fetisenko Olga L.
Published: March 2024

The article, based on materials from two archival funds of the Manuscript Department of the Pushkin House, recreates in detail one of the most significant components of the spiritual life of Evgeny Ivanov (1879–1942), a writer and religious thinker, a close friend of А. Blok. It is the history of his long-term worship of Vera Komissarzhevskaya, which influenced not only the formation of his worldview but also his work (first of all, his unfinished articles about H. Ibsen’s female characters, about the high destiny of theatre actors, about religious faith). Ivanov found himself in a situation of religious dual faith (Orthodoxy and the rudiments of the Khlystism, Christianity and the interest in Slavic paganism), being at the same time in platonic love with two women under the name Vera — Komissarzhevskaya and V.N. Dyukova, his cousin. The materials presented in the study, including previously unpublished fragments of the diary, can be considered as a kind of backlight to the history of the creation of the poem “On the Death of Komissarzhevskaya” by A. Blok (1910). Most importantly, they explain the appearance in this text of the image of “promised spring.”

Multiscale Learnable Physical Modeling and Data Assimilation Framework: Application to High-Resolution Regionalized Hydrological Simulation of Flash Floods
Authors: Huynh Ngo Nghi Truyen , Garambois Pierre-André , Renard Benjamin , Colleoni François , Monnier Jérôme , Roux Hélène
Published: March 2024

To advance the discovery of scale-relevant hydrological laws while
better exploiting massive multi-source data, merging machine learning
into process-based modeling is compelling, as recently demonstrated in
lumped hydrological modeling. This article introduces MLPM-PR, a new and
powerful framework standing for Multiscale spatially distributed
Learnable Physical Modeling and learnable Parameter Regionalization with
data assimilation. MLPM-PR crucially builds on a differentiable model
that couples (i) two neural networks for processes learning and
parameters regionalization, (ii) grid-based conceptual hydrological
operators, and (iii) a simple kinematic wave routing. The approach is
tested on a challenging flash flood-prone multi-catchment modeling setup
at high spatio-temporal resolution (1km, 1h). Discharge prediction
performances highlight the accuracy and robustness of MLPM-PR compared
to classical approaches in both spatial and temporal validation. The
physical interpretability of spatially distributed parameters and
internal states shows the nuanced behavior of the hybrid model and its
adaptability to diverse hydrological responses.
Endothelial Cells and Blood-Brain Barrier (BBB): The Key Factors in Ineffective Reperfusion Outcomes
Authors: qianhui zhao , Geng Xiaokun , Kim enoch , Ding Yuchuan
Published: March 2024

In the realm of neurointerventional treatment after ischemic stroke,
ineffective reperfusion represents a significant challenge, with the
integrity of the blood-brain barrier (BBB) serving as a pivotal
determinant of outcomes. This review sheds light on the unique
characteristics and roles of brain endothelial cells within the context
of stroke with ineffective reperfusion. We address the distinctiveness
of brain endothelial cells relative to their counterparts in different
tissues, outlining their pathophysiological transformations, functional
impairments, and inflammatory cascades post-stroke. The differential
gene expression between brain endothelial cells and those from other
organs provide a deeper understanding of their intrinsic roles in
neuroprotective therapy. Looking ahead, exploring analogies between
brain endothelial cells and those from organs with similar
ischemia-reperfusion injury profiles could lead to innovative
therapeutic strategies. This review highlights the paramount importance
of understanding the nuanced roles of endothelial cells in mediating BBB
dynamics, ultimately influencing reperfusion outcomes.
Clinical features and outcomes of horses presenting with equine immune mediated keratitis (IMMK) to two veterinary hospitals in the United Kingdom and Finland: 96 cases (2009-2021).
Authors: Preston Juliette F. , Mustikka Minna P. , Fischer Maria-Christine , Dunkel Bettina
Published: March 2024

Background: Limited literature exists regarding equine Immune
Mediated Keratitis (IMMK) in Europe. North America-based publications
describe minimal blepharospasm, rare corneal ulceration and no uveitis;
clinical impression suggests that these signs are common in Europe.
Objectives. Assess the prevalence of blepharospasm, corneal
ulceration and uveitis and their impact on outcome in horses diagnosed
with IMMK in European countries. Study design: Retrospective case
series of 95 horses with IMMK in the UK and Finland. Methods.
Clinical records of horses with IMMK were retrospectively evaluated. The
UK and Finland populations were comparable; therefore, descriptive
statistics were performed on combined data on subtypes of IMMK and
clinical features. Odds ratios (OR) and confidence intervals (CI) were
calculated for impact of blepharospasm, ulceration or presence of
uveitis on the outcome of enucleation and treatment duration.
Results. IMMK subtype was classified as 10/95 (10.5%)
epithelial, 50/95 (52.6%) anterior stromal, 15/95 (15.8%) mid-stromal,
4/95 (4.2%) endothelial cases and 16/19 (16.8%) unrecorded.
Blepharospasm was documented in 35/95 (36.8%), corneal ulceration in
28/95 (29.5%), and signs of uveitis in 24/95 (25.4%) of horses.
Increased odds of enucleation were associated with the presence of
blepharospasm (OR 5.9, 95% CI 1.7-20.8), corneal ulceration (OR 3.3,
95% CI 1.0-10.5) and signs of uveitis (OR 8.6, 95% CI 2.5-29.6). The
presence of blepharospasm, corneal ulceration or uveitis did not
significantly alter the odds of ongoing medication. Main
limitations: Data were collected over a wide timeframe and the
diagnosis was mainly made without histopathology. A broad definition of
uveitis was used and there was a bias towards complicated cases being
retained for follow up. Conclusions. The clinical features of
IMMK were similar between two geographically distinct European countries
but different to findings described in the USA. Blepharospasm, corneal
ulceration and signs of uveitis can occur with IMMK and increase the
odds of enucleation.

Material hardship and use of social safety net programs among LGBT adults and their families
Authors: Henderson Emmett R. , Hotchkiss Maiya , Blosnich John R.
Published: March 2024

Sexual and gender minority (SGM) people experience higher levels of
economic insecurity and poverty compared to non-SGM people. Social
safety net programs may reduce this disparity, but the uptake of these
programs among SGM adults has rarely been assessed. We conducted a
secondary data analysis of the 2018-2020 Well-Being and Basic Needs
Survey to compare differences in material hardship and social safety net
program utilization between SGM and non-SGM adults in the United States.
SGM participants were more likely to report food insecurity, utilities
hardship, medical hardship, and multiple material hardships. SGM adults
had higher odds compared to non-SGM adults of using SNAP, income- or
disability-based insurance, SSI or SSDI, and housing assistance. There
were no differences in use of WIC, reduced-price/free school lunch
benefits, or charitable food. Future studies are needed to evaluate the
efficacy of the social safety net programs for reducing material
hardship.
OPTIMIZED SOLVENT-FREE RECRYSTALLIZATION PURIFICATION
Authors: Fickelscherer Richard , McGarrity Mitchell , Richardson Madison , Gangaraju Ritika , Tierney Daniel
Published: March 2024

This treatment describes the details of three possible methodical
procedures for determining the optimal operating conditions for the
recrystallization separations of solid mixtures. One of these procedures
uses traditional liquid solvents, another employs solid entrainers
(i.e., solid solvents), while the third performs thermal stripping
predictions that are possible without using any type of solvents.
Optimization of each specific procedure is accomplished by always
maximizing the calculated recovery yield of the desired solid product.
Performing such calculations requires a highly reliable method for
accurately determining the mutual saturated liquid phase solubility of
all solutes being separated. The accuracy possible for such solubility
predictions utilizing two direct methods for doing so were
experimentally demonstrated with various combinations of four measured
test solids in three representative liquid solvents at two different
temperatures. Our procedure was then applied to optimally separate
various representative mixtures of these test solids without using any
liquid solvents.

High quantum yields and energy transfer efficiency are favored by
luminescent thermometers. In this work, dehydration process has been
applied to remove 12 coordinated and isolated water molecules of 1
dimensional chains [Ln2(mip)3(H2O)84H2O]∞ (abbreviated as Ln2MIP).
The overall quantum yields of Tb3+ has been improved to 80% from 47.5%
after dehydration. In dehydrated Gd0.2Tb1.08Eu0.72MIP, the energy
transfer efficiency between Tb3+ and Eu3+ reaches 96% from 27% that
result in improving the overall quantum yields of Eu3+ from 8.4% to
13.1%. Compared with hydrated Gd0.2Tb1.08Eu0.72MIP, the dehydrated
phase presents 1.5 times temperature sensing range between IEu/ITb and
temperature with improved Sre (0.564 % K-1). At the same time, the
intensity of Eu3+ at 618 nm displays excellent temperature sensing
ability from 77 K to 300 K after dehydration with improved quantum
yields

Microchannel reactors are being widely used in the fields such as
chemical synthesis, catalytic reactions, high temperature, and high
pressure reactions because of their green, accurate, and controllable
benefits. In this paper, a model of reaction kinetics was established
based on 1-tetradecene and sulfur trioxide solution as raw materials,
and the reaction kinetic parameters were calculated based on the
experimental data under the microscale conditions using the differential
method, and the reaction kinetic model was verified. The results showed
that the kinetic equation of 1-tetradecene sulfonation reaction in the
microchannel reactor was established, the preexponential factor A,
activation energy Ea of the reaction and the 95% confidence interval of
them were made sure.
Sediment oxygen uptake and hypoxia: a simple mass-balance model for estuaries and coastal oceans
Authors: Sun Jing , Yu Liuqian , Yang Xingyu , Gan Jianping , Yin Hongbin , Li Jiying
Published: March 2024

Hypoxia is increasing in coastal oceans. This is because eutrophication
has increased oxygen consumption, while less oxygen is replenished to
the bottom under stronger stratification. Quantifying these
biogeochemical and physical drivers is important for management and
predicting future trends. By using observations from the Pearl River
Estuary (PRE) region (10-70 m deep) and similar coastal systems, this
paper introduces a simple analysis to quantify both the biogeochemical
and physical drivers of hypoxia. We show that in the PRE region,
sediment respires >60% of organic matter produced in the
water column, leading to high sediment oxygen uptake (average 41.1±16.3
mmol m-2 d-1) and shallow oxygen penetrations (2-7 mm). The sediment’s
effect on the bottom oxygen loss becomes stronger with the reducing
thickness of the bottom boundary layer. We then construct a generic
mass-balance model to quantify oxygen loss, determine timescales of
hypoxia formation, and explain within- and cross-system variabilities.
Revisiting the Veljusa frescoes: Notes on the iconographic program of the south parekklesion
Authors: Zivkovic Milos , Milanovic Ljubomir
Published: March 2024

The paper discusses the iconographic program of the frescoes in the south
parekklesion of the Church of the Virgin Eleousa at the Veljusa Monastery,
the foundation of Manuel, Bishop of Strumitza, built in 1080. It focuses on
the figure of St. Niphon or, more specifically, the cult and iconography of
this saint, whose representations in art are quite uncommon. It considers
several images of St. Niphon in Serbian medieval painting that previous
research has failed to take into account. Then, it reexamines the view that
this saint was the patron of the chapel, especially the claim that one of
his visions was painted in the apse.
Η σελασφοροσ - the Prizren representations of the Virgin the Light-bearer (Philological appendix by Darko Todorovic)
Authors: Vojvodic Dragan
Published: March 2024

The paper discusses the distinctive and mutually almost identical apsidal
representations in three churches in Prizren and its area. They comprise the
Virgin enthroned, the Child Christ in her lap, and the archangels bowing to
them, their wings raised along the edge of the conch. In two of those
monuments, the accompanying inscription describes the Mother of God as the
Light-bearer (? ??????????). This epithet has not been recorded so far in
her depictions in Byzantine and post-Byzantine art. Whatever the origin of
the distinctive solution in the apses of the three Prizren churches from
various periods might have been, it was widely accepted in the Prizren area,
becoming part of the local tradition.
The name of the people onomastics and immigration in the chronicle of Ioannina
Authors: Osswald Brendan
Published: March 2024

This paper is dedicated to the anthroponyms of people of foreign origin
mentioned in the Chronicle of Ioannina. Firstly, it warns against the risk
inherent in reconstructing a hypothetical original form of the foreign
anthroponyms transmitted in Greek by the Chronicle: on the one hand, such
reconstructions involve a degree of uncertainty since they are not attested
in the sources; on the other hand, they present as irremediably foreign
people who, to varying degrees, were integrated into Epirotic society. It
then draws up a catalogue of these people, classified by Slavic, Western or
Albanian origin. By reviewing the sources and examining the manuscript
tradition, it aims to re-examine the relevance of historiographical
traditions and attempt to define the most appropriate names for each person.
In some cases, it is difficult to decide in favour of a particular solution,
insofar as these figures lived in a multilingual environment and were the
product of a migratory path that placed them at the junction of several
cultures. The choice of a particular name is tantamount to erasing this
complexity and turning these individuals into one-dimensional characters.
The article also calls into question certain well-established
historiographical traditions, in particular the use of the anthroponyms
Preljubovic, Orsini, Spata and Zenevesi, which for various reasons should be
replaced by Prealimpos, Angelos Doukas Komnenos, Spatas or Shpata and
Zenebishi respectively.
On the role of Bulgarian fortresses in the war of 976-1018
Authors: Krsmanovic Bojana
Published: March 2024

After 1018/1019, the organization of Byzantine rule in the interior regions
of the Balkans rested on the administration that John I Tzimiskes
established in the areas taken from Bulgaria after 971 and the experience
Basil II acquired during the war of 976-1018/1019 against Samuel and his
successors. The sources attest that the struggle for Bulgarian independence
relied on a dense network of fortresses in the interior of the Balkans.
Accounts of the war of 976-1018/1019 by Byzantine authors show that, based
on certain criteria, we can identify the dominant fortresses that served as
the centers of Bulgarian resistance. Basil took control of most of those
fortresses by their surrender. The way in which the Balkan interior was
subdued led to Byzantium?s reliance on church organization to establish its
rule in the post-1018/1019 period. During the reign of Basil II and shortly
after his death, the Archbishopric of Ohrid had a twofold role. This
institution, on the one hand, ensured lasting peace in the Balkans and, on
the other, remained the only guardian of the subjugated people?s identity.
However, in the mid-11th century, Byzantium already began to openly pursue a
policy that almost exclusively favored Constantinople?s interests in the
Balkans.

Objective: Tubulointerstitial injury contributes to diabetic kidney disease (DKD) progression. We tested tubular biomarker associations with DKD development in type 1 diabetes (T1D). Research Design and Methods: A case-cohort study examined associations of tubular biomarkers, measured across 7 time points spanning ~30 years, with incident macroalbuminuria (‘severely elevated albuminuria’, urinary albumin excretion rate ≥300mg/day) and sustained low eGFR (persistent eGFR<60ml/min/1.73m2) in DCCT/EDIC. Biomarkers included: KIM-1, sTNFR1 in serum/plasma; MCP-1, EGF in urine; a composite tubular secretion score reflecting secreted solute clearance. Biomarkers were assessed using single values, as mean values from consecutive time points, and as change over consecutive time points, each as time-updated exposures. Results: At baseline, mean diabetes duration was 5.9 years, with mean HbA1c 8.9%, eGFR 125ml/min/1.73m2, and AER 16mg/day. 4.8 and 3.5 cases per 1000 person-years of macroalbuminuria and low eGFR were observed, respectively. Assessed as single biomarker values, KIM-1 was associated with risk of subsequent macroalbuminuria and low eGFR (hazard ratio [HR] per 20% higher biomarker, HR=1.11 [95% CI 1.06,1.16] and HR=1.12 [95% CI 1.04,1.21], respectively); sTNFR1 was associated with subsequent macroalbuminuria (HR=1.14 [95% CI 1.03,1.25]). Mean KIM-1 and EGF to MCP-1 ratio were associated with subsequent low eGFR. In slope analyses, increases in KIM-1 and sTNFR1 were associated with subsequent macroalbuminuria (per 20% biomarker increase, HR=1.81 [95% CI 1.40,2.34] and HR=1.95 [95% CI 1.18,3.21], respectively) and low eGFR (HR=2.26 [95% CI 1.65,3.09] and HR=2.94 [95% CI 1.39,6.23], respectively). Conclusions: Serial KIM-1 and sTNFR1 are associated with incident macroalbuminuria and sustained low eGFR in T1D.

Factors associated with fatigue among people who have returned to work after stroke: an exploratory study
Authors: Norlander Anna , Lindgren Ingrid , Brogårdh Christina
Published: March 2024

Objective: To explore the associations between fatigue impact and (a) personal and stroke-related characteristics, (b) functional impairments and (c) work-related factors among individuals who have returned to work after stroke.
Design: A cross-sectional exploratory study.
Subjects: 87 working stroke survivors.
Methods: This study comprises data from a postal survey targeting work ability and perceived stroke-related consequences 1 year after stroke. Fatigue was evaluated using the Fatigue Severity Scale (FSS). Factors associated with having fatigue (FSS total score ≥ 4) were identified using univariable and multivariable logistic regression analyses. Three domain-specific multivariable models and 1 final combined model were created.
Results: Fatigue was reported by 43% of the participants. Several factors representing all the investigated domains were associated with fatigue. In the final combined regression model, self-perceived low cognitive functioning, low decision control at work and high quantitative job demands had the strongest independent effects on the odds of having fatigue.
Conclusion: Among people who were working 1 year after stroke, fatigue was associated with both personal and stroke-related characteristics as well as functional impairments and work-related factors. This highlights the complex nature of post-stroke fatigue. Fatigue management interventions should have a comprehensive approach and also consider the work environment.
Prosopis Africana Extracts as Potential Natural Alternatives to Synthetic Antibiotics and a Key for Sustainable Broiler Production: A Review
Authors: AO John
Published: March 2024

The chicken sector is more vulnerable to antimicrobial resistance, the buildup of toxic or dangerous residues in meat and eggs, and environmental contamination as a result of the widespread and careless use of antibiotics in most nations. Natural solutions, such as medicinal plants, are required to address these issues. These plants have been shown to contain a variety of phytochemicals, including phenols, flavonoids, terpenoids, tannins, alkaloids, and saponins. These chemicals endow plants with a multitude of medicinal qualities. One of the many alternatives to antibiotics is Prosopis africana extract, which includes stem bark, leaves, roots, and their essential oils. Antioxidant, antibacterial, antifungal, anti-helminthic, antiviral, hepatoprotective, immune-stimulatory, and antimicrobial properties are among the many pharmacological activity of P. africana preparations. They are also an abundant supplier of vital minerals and amino acids that support enzyme function and provide defense against the effects of oxidative stress. Using extracts from Prosopis africana is the way forward for effective chicken production, environmental sustainability and food hygiene.

This comprehensive study delves into the intricate interplay between temperature trends and land cover dynamics in the Kara region, offering robust insights into the evolving climate and environmental patterns. Employing the Mann-Kendall trend test, our analysis reveals a statistically significant and consistent warming trend over the study period. The observed low p-values, positive Tau values, and upward-sloping regression lines emphasize the urgent need for proactive measures to address the climate-related challenges faced by the region. Simultaneously, a meticulous correlation analysis explores the relationships between land surface temperature (LST) and key land metrics- farms, barelands, built-ups, forests, and water bodies. Farmlands exhibit a noteworthy and statistically significant negative correlation of −0.74 with LST (p < 0.05), indicating a cooling influence and supported by a substantial 43.8% predictive power. Conversely, barelands and built-ups demonstrate strong positive correlations of 0.89 and 0.78, respectively, with LST both statistically significant at the 95% confidence level (p < 0.05), emphasizing their considerable warming impact. Forests and water bodies, with moderate negative correlations of −0.65 and −0.54, maintain statistical significance (p < 0.05), indicating their role in temperature moderation, supported by 8.5% and 13% significance. The inclusion of Sen’s slope values further enriches the analysis, providing quantitative insights into the rate of temperature change. The positive slope values underscore the increasing trend in temperatures over each respective decade. The observed statistical significances, Tau values, and Sen’s slope values accentuate the importance of these relationships for effective land management and environmental planning. Recognizing the cooling influence of farmlands suggests their potential use in strategic urban planning to mitigate temperature increases. Conversely, the warming impact of barelands and built-ups emphasizes the need for sustainable urban development practices to counteract rising temperatures in urbanized regions. Additionally, the cooling influence of forests and water bodies underscores their crucial role in temperature moderation.
Past Refusals, Reasons and Future of COVID Vaccinations in Colleges
Authors: Waikar Avinash , Cappel Samuel , Jodhpurkar Uday
Published: March 2024

A significant portion of the adult and college student populations have been observed to be reluctant to get vaccinated against COVID-19. COVID-19 is still a threat and the unvaccinated students may yet pose a risk of spreading the disease in the case of a new variant. Many experts believe that COVID is here to stay and new variants are likely to come around. Thus, there is a need to examine the causes of vaccination refusal among college students so that efforts could be made to increase the vaccination rates if needed. Sources of information were classified into three categories: Scientific, Friends/Relatives, and Social Media. Results indicated that “No Faith in Government or Vaccine” was the dominant reason. Differences were noted with respect to gender. Refusal Reasonings also were correlated related to the source of information. The majority of respondents who refused the vaccine would reportedly refuse future COVID-related vaccines. This research may aid in future efforts to reduce reluctance among college-age students to accept the vaccine.
