AN ANALYSIS ON SOCIO-ECONOMIC PHENOMENA OF SCHEDULED CASTE IN INDIA
Authors: Mahendra Dodamani  , Dr. Subaschandra C Natikar
Published: August 2023

The socio-economic empowerment of Scheduled Castes (SCs) in India has been a persistent concern, rooted in historical marginalization and discrimination. This analysis delves into the complex interplay of socio-economic phenomena that shape the lives of the SC community. While progress has been made towards addressing overt discrimination, disparities in education, healthcare, employment, and economic resources persist. This study examines the intricate intersection of socio-economic factors and caste dynamics, influencing wealth distribution, access to services, and political representation. Through historical contexts, policy interventions, and contemporary challenges, patterns that shape the socio-economic trajectory of SCs are discerned. One promising avenue for empowerment is land ownership, symbolizing economic stability and social status. Historically, SCs faced land deprivation, perpetuating cycles of poverty. Initiatives like the Empowering SCs through Land Ownership Scheme strive to rectify this by providing access to land ownership. The analysis underscores the importance of education as a vehicle for upward mobility and highlights the need for accessible healthcare services. It explores the challenges SCs face in securing better job opportunities and emphasizes the role of self-help groups in improving livelihoods. Ultimately, this study contributes to a nuanced discourse on social equity, policy impact, and the journey towards an inclusive society. It calls for comprehensive efforts to eliminate educational disparities, raise awareness of available facilities, and empower SCs to improve their socio-economic conditions. Through a holistic approach, India can aspire to uplift the socio-economic status of SCs and foster a more just and equitable society for all its citizens.

Prevalence and Knowledge of Polycystic Ovarian Syndrome of Female Students at a University in Utah
Authors: Robinson Madison , Larson Abigail
Published: August 2023

Polycystic ovarian syndrome (PCOS) is a common disorder among females of reproductive age. PCOS often goes undiagnosed or is misdiagnosed due to a lack of education, awareness, or communication of symptoms on the part of the woman and/or health care provider. The purpose of this study is to measure the prevalence of PCOS and to determine the current level of knowledge of this topic among female students attending a university in Utah. Data was gathered using an online survey that was distributed to biological females attending the university. The survey included measurements on the prevalence of females diagnosed with PCOS and the awareness of symptoms associated with PCOS. It also measured the various treatment techniques used to manage symptoms and the efficacy of those symptom management techniques. 351 respondents met the inclusion criteria and completed the entire survey. 9% (n=30) of respondents have been clinically diagnosed with PCOS and 28% (n=100) of respondents were unaware or have never heard of PCOS. Findings indicate there is a general lack of knowledge of PCOS and related symptoms and treatments among biological female students attending the university. Making information about PCOS more available to the campus community would be beneficial for several reasons. These include increased symptom awareness, support for individuals diagnosed with PCOS, improved knowledge of potential treatment options, and additional resources for those struggling with PCOS associated symptoms. It may also help those that do not have the disorder to better understand the distressing symptoms others are experiencing and reach out for help if they are experiencing symptoms associated with PCOS.

Published: August 2023

A história é um caminho acidentado, marcado simultaneamente por progressos e regressos derivados de fatores que são incontroláveis, de modo que, mesmo no interior de um avanço político-social ou de inovações tecnológicas, habitam as correlações de forças que operam contra o êxito das conquistas. Este é o dado da realidade que move Edgar Morin ao longo dos quatro capítulos do livro Despertemos, um manifesto contra a displicência sociológica, política e cultural.

Published: August 2023

Phantom limb pain (PLP) often occurs in post - amputation patients. Acupuncture may have a positive effect in treating PLP. This study aimed to observe the changes in plasma neuropeptide Y (NPY) and prostaglandin E2 (PGE2) levels before and after acupuncture in patients with PLP, and
to evaluate the effects of acupuncture on the peripheral circulation of residual limbs by measuring the skin blood flow (SBF) and oxygen saturation (SO2 ). Six amputees participated in this study. After 28 days of treatment, the PGE2 was significantly lower compared with that at
day 0. The NPY was lower compared with that at day 0. The SBF and SO2 change percentage in the intervention and recovery stages of each acupuncture treatment were all significantly increased. Moreover, the visual analog scale scores of PLP showed that patients felt their PLP disappeared
completely and were satisfied with the acupuncture treatment. This study suggests that acupuncture was effective in treating PLP, and PGE2 and NPY may be regulators of pain transmission in PLP.

This study examined the influence of educational tools in digital libraries on the personalised learning experiences of final-year economics education students in public universities in Lagos State, Nigeria. A descriptive research design was employed, with the use of a questionnaire tagged Digital Libraries and Personalised Learning Experiences of Students Questionnaire (DLPLESQ) as an instrument of data collection. A total of 212 final-year economics education students were selected for the study using the snowball sampling technique. Descriptive statistics such as frequency distribution, percentage, mean, and standard deviation were used to provide answers to research questions. Additionally, inferential statistics in the form of regression analysis was used to test the relevant hypothesis. The findings revealed that digital library tools have a significant positive impact on students’ personalised learning experiences of students ( = 2.002; P<0.05). The study also demonstrated that final-year Economics education students are “Not Aware” of the resources in digital libraries in public universities in Lagos State, Nigeria. Out of the 13 digital library resources listed, sampled students seem to be “Aware” of only three resources which are “Google Scholar,” “Oxford Academic,” and “Research4life”. Furthermore, the study showed that final-year Economics education students make use of the digital library resources “Monthly”. Based on these findings, the study recommended strategies to enhance the utilisation of digital libraries, such as improving access to devices and internet connectivity, providing training programs to enhance digital literacy skills, and integrating digital library resources into the economics education curriculum

Based on the graphic of the INTO movement, Current, Cash, Quick Ratio we can see the relationship benveen invent.ory tumover (INTO) with liquidity (Cash Ratio, Quick Ratio and Current Ratio) of PT Indofood Tbk in 2007 until the year 2009 showed that when inventory turnaround went slow, the company 's liquidity would decrease. And on the contrary, the company's liquidity would increase when the inventory tumaround was fast. In 2010 and 2011 showed a decreased inventory turnover but increased liquidity, this is due to the presence ofotherfactors influencing company 's liquidity such as the management of the company's most liquid current assets. Overall, inventory tumaround at PT. Mandom, Tbk on every year in the period 2007 to 2011 are fluctuating. This can be seen from the increasing and decreasing value of the company. We can still say that PT. Mandom Tbk still holds consumer preferences, and can still fulfil consumers ' demands, and being innovative at the same time. Qualitatively, the company experienced a slower performance but managed to slowly get into performance again. For 5 years, 2010 is the year when the company experienced the highest inventory turnover achieved as much as 4.78 times, and 2008 was the lowest inventory turnover as much as 3.42.

A Study of Ensemble Deep Learning Method Using Transfer Learning for Horticultural Data Classification
Authors: ATALI Gökhan , KIRCI Sedanur
Published: August 2023

Deep learning is an important discipline in which human-specific problems are solved with the help of machines with advanced hardware power. It is seen this discipline is widely used in the fields of industry, health, defense industry, and sports. In addition, the use of deep learning in the field of horticulture is an important requirement. With the integration of deep learning into horticulture, to do product classification is very important for increasing productivity and production.

In this study, a method using ensemble learning is proposed to improve the accuracy of the classification problem for horticultural data. For this method, a new dataset was created, containing a total of 24421 images and 15 crop classes, independent of data augmentation. In order to train this created data set with the help of the proposed method, a hierarchical structure has been designed in which the output of one model is the input of the other model. A total of 7 pre-trained models were used in the experimental studies of the proposed method. Since this method is in an ensemble structure, it is possible to add or remove pre-trained models from the structure. With the help of experimental studies, a performance analysis of the proposed method, which is compared with the traditional CNN method, has been made. As a result of these analyses, it has been observed that the proposed method works 3% more successfully.
UNRAVELLING EFFECTS OF PROJECT COMPLEXITY ON PROJECT SUCCESS AND PROJECT MANAGEMENT SUCCESS: A META-ANALYTIC REVIEW
Authors: Hu Zhibin , Wu Guangdong , Zheng Junwei , Zhao Xianbo , Zuo Jian
Published: August 2023

Construction project complexity can be daunting, so both academics and practitioners have been looking for guidance. Previous studies have attempted to reconcile the inconsistencies and complexities in the relationships among project complexity, project success, and project management success. However, such research has failed to establish these clear relationships. Accordingly, the approach of systematic review and meta-analysis is applied in this study to investigate and compare how different project complexity affects project success and project management success by selecting 22 articles and 77 effect sizes. The results indicate that integrational complexity significantly positively affects project success, whereas it is not significantly negatively associated with project management success. Within a technical-organizational-environmental (TOE) framework, effects of organizational, environmental, and technical complexity on project success and project management success are also discussed here. A possible moderator (the national/regional income level) is tested and verified. The findings contribute to the system of knowledge on project complexity and provide guidelines for decision-makers to achieve a balance between project success and project management success in routine operation of construction projects.

We present high-resolution high-sensitivity observations of the Class 0 protostar RCrA IRS5N as part of the Atacama Large Milimeter/submilimeter Array large program Early Planet Formation in Embedded Disks. The 1.3 mm continuum emission reveals a flattened continuum structure around IRS5N, consistent with a protostellar disk in the early phases of evolution. The continuum emission appears smooth and shows no substructures. However, a brightness asymmetry is observed along the minor axis of the disk, suggesting that the disk is optically and geometrically thick. We estimate the disk mass to be between 0.007 and 0.02 M
⊙. Furthermore, molecular emission has been detected from various species, including C18O (2–1), 12CO (2–1), 13CO (2–1), and H2CO (30,3 − 20,2, 32,1 − 22,0, and 32,2 − 22,1). By conducting a position–velocity analysis of the C18O (2–1) emission, we find that the disk of IRS5N exhibits characteristics consistent with Keplerian rotation around a central protostar with a mass of approximately 0.3 M
⊙. Additionally, we observe dust continuum emission from the nearby binary source IRS5a/b. The emission in 12CO toward IRS5a/b seems to emanate from IRS5b and flow into IRS5a, suggesting material transport between their mutual orbits. The lack of a detected outflow and large-scale negatives in 12CO observed toward IRS5N suggests that much of the flux from IRS5N is being resolved out. Using a 1D radiative transfer model, we infer the mass of the envelope surrounding IRS5N to be ∼1.2 M
⊙. Due to this substantial surrounding envelope, the central IRS5N protostar is expected to be significantly more massive in the future.
Rubin Observatory’s Survey Strategy Performance for Tidal Disruption Events
Authors: Bučar Bricman K. , van Velzen S. , Nicholl M. , Gomboc A.
Published: August 2023

Tidal disruption events (TDEs) are rare transients, which are considered as promising tools for probing supermassive black holes in quiescent galaxies. The majority of the ≈60 known TDEs have been discovered with time-domain surveys in the last two decades. Currently, ≈10 TDEs are discovered per year, and this number will increase with the Legacy Survey of Space and Time (LSST) at the Rubin Observatory. This work evaluates LSST survey strategies in view of their performance in identifying TDEs. We assume that TDEs can be identified photometrically based on their colors, particularly in the u band, and will be scientifically useful if we can detect the light-curve peak to derive physical quantities. We define the requirements for the Rubin light curves that are needed to achieve this (detections prepeak, postpeak, and in different bands to measure color). We then inject model light curves into the Operations Simulator and calculate the fractions of TDEs passing our requirements for several strategies. We find that under the baseline strategy, ≈1.5% of simulated TDEs fulfill our detection criteria, while this number increases when more time is devoted to u-band observations. An ideal observing strategy for the photometric identification of TDEs would have longer u-band exposures, which should not come at the expense of fewer u-band visits. A filter distribution weighted toward more observing time in bluer bands, intranight visits in different filters, and strategies with frequent sampling leading to higher-quality light curves are preferred. We find that these strategies benefiting TDE science do not impact significantly other science cases.
Hidden Companions to Intermediate-mass Stars. X. Solving for the Mass Ratio in the Spectroscopic Binary Zubenelgenubi = α
2 Librae*
Authors: Waisberg Idel , Klein Ygal , Katz Boaz
Published: August 2023

Zubenelgenubi = α
2 Librae is a nearby double-lined spectroscopic binary that forms a quadruple system with α
1 Librae. The radial velocity amplitude for the rapidly rotating primary is subject to a systematic uncertainty and as a result only a lower limit q = 0.81 to the mass ratio has been previously reported. Here we present a VLTI/GRAVITY interferometric observation of Zubenelgenubi in which we measured a K band flux ratio of 74.7%, resulting in isochrone masses M
Aa = 1.95 M
⊙ and M
Ab = 1.79 M
⊙ (q = 0.92). The fact that the projected rotational velocities differ by a factor of three despite the similar masses suggests that the stellar spin axes are significantly misaligned in spite of the small semimajor axis a = 0.52 au or alternatively that the primary is a merger product.

Published: August 2023

Chronic graft-versus-host disease (cGVHD) involves multiple organs, but little is known about bone marrow (BM) alterations caused by cGVHD. In mice and humans, we found that cGVHD is associated with BM fibrosis resulting in T cell infiltration, IgG deposition, and hematopoietic dysfunction. Macrophages and Nestin+ mesenchymal stromal cells (MSCs) participated in the process of BM fibrosis during BM cGVHD development. BM macrophage numbers were significantly increased in mice and humans with BM fibrosis associated with cGVHD. Amplified macrophages produced TGF-β1, which recruited Nestin+ MSCs forming clusters, and Nestin+ MSCs later differentiated into fibroblasts, a process mediated by increased TGF-β/Smad signaling. TLR4/MyD88-mediated activation of endoplasmic reticulum (ER) stress in macrophages is associated with fibrosis by increasing Nestin+ MSC migration and differentiation into fibroblasts. Depletion of macrophages by clodronate-containing liposomes and inhibition of ER stress by 4-phenylbutyric acid reversed BM fibrosis by inhibiting fibroblast differentiation. These studies provide insights into the pathogenesis of BM fibrosis during cGVHD development.

The aim of our study was to investigate short- and medium-term survival in patients with sudden cardiac death (SCD) after resuscitation. We continued a retrospective study at the University of Pécs from April 2018 to December 2019. 192 patients with SCD were selected. Exclusion criteria were incomplete documentation and unstable rhythm, after which we continued the study with 181 patients. Our data were obtained from documents recorded by the Emergency Department. The study population was divided into two groups, with proven shockable (I) and non-shockable (II) initial rhythm, and their data were compared at hospital discharge, at 1 month, and at 3 months. The main endpoint was the mortality between the two groups. Our results already showed that hospital survival was significantly higher in the shockable rhythm group than in the non-shockable group (62% vs. 38%, P=0.002). We also obtained similar results for 1-month survival (54% vs. 16%, P=0.004). When risk factors were examined, there was a significant difference in the survival of diabetic (P=0.001) and hypertensive patients (P=0.001). Patients with shockable rhythm have significantly better survival rates.

Background: Hemostatic dysfunction during extracorporeal membrane oxygenation (ECMO) due to blood-circuit interaction and the consequences of shear stress imposed by flow rates lead to rapid coagulation cascade and thrombus formation in the ECMO system and blood vessels. We aimed to identify the incidence and risk factors for cannula-associated arterial thrombosis (CaAT) post-decannulation. Methods: A retrospective study of patients undergoing arterial cannula removal following ECMO was performed. We evaluated the incidence of CaAT and compared the characteristics, ECMO machine parameters, cannula sizes, number of blood products transfused during ECMO, and daily hemostasis parameters in patients with and without CaAT. Multivariate analysis identified the risk factors for CaAT. Results: Forty-seven patients requiring venoarterial ECMO (VA-ECMO) or hybrid methods were recruited for thrombosis screening. The median Sequential Organ Failure Assessment score was 11 (interquartile range, 8–13). CaAT occurred in 29 patients (61.7%), with thrombosis in the superficial femoral artery accounting for 51.7% of cases. The rate of limb ischemia complications in the CaAT group was 17.2%. Multivariate analysis determined that the ECMO flow rate–body surface area (BSA) ratio (100 ml/min/m2) was an independent factor for CaAT, with an odds ratio of 0.79 (95% confidence interval, 0.66–0.95, P=0.014). Conclusions: We found that the incidence of CaAT was 61.7% following successful decannulation from VA-ECMO or hybrid modes, and the ECMO flow rate–BSA ratio was an independent risk factor for CaAT. We suggest screening for arterial thrombosis following VA-ECMO, and further research is needed to determine the risks and benefits of such screening.

On the Convergence of Random Fourier-Jacobi Series of Continuous functions
Authors: Maharana Partiswari , Sahoo Sabita
Published: August 2023

The interest in orthogonal polynomials and random Fourier series in numerous
branches of science and a few studies on random Fourier series in orthogonal
polynomials inspired us to focus on random Fourier series in Jacobi
polynomials. In the present note, an attempt has been made to investigate the
stochastic convergence of some random Jacobi series. We looked into the random
series $\sum_{n=0}^\infty d_n r_n(\omega)\varphi_n(y)$ in orthogonal
polynomials $\varphi_n(y)$ with random variables $r_n(\omega).$ The random
coefficients $r_n(\omega)$ are the Fourier-Jacobi coefficients of continuous
stochastic processes such as symmetric stable process and Wiener process. The
$\varphi_n(y)$ are chosen to be the Jacobi polynomials and their variants
depending on the random variables associated with the kind of stochastic
process. The convergence of random series is established for different
parameters $\gamma,\delta$ of the Jacobi polynomials with corresponding choice
of the scalars $d_n$ which are Fourier-Jacobi coefficients of a suitable class
of continuous functions. The sum functions of the random Fourier-Jacobi series
associated with continuous stochastic processes are observed to be the
stochastic integrals. The continuity properties of the sum functions are also
discussed.
The effect of Facebook behaviors on the prediction of review helpfulness
Authors: Ben-Abdallah Emna , Boukadi Khouloud
Published: August 2023

Facebook reviews contain reviews and reviewers' information and include a set of likes, comments, sharing, and reactions called Facebook Behaviors (FBs). We extend existing research on review helpfulness to fit Facebook reviews by demonstrating that Facebook behaviors can impact review helpfulness. This study proposes a theoretical model that explains reviews' helpfulness based on FBs and baseline features. The model is empirically validated using a real Facebook data set and different feature selection methods (FS) to determine the importance level of such features to maximize the helpfulness prediction. Consequently, a combination of the impactful features is identified based on a robust and effective model. In this context, the like and love behaviors deliver the best predictive performance. Furthermore, we employ different classification techniques and a set of influencer features. The results showed the performance of the proposed model by 0.925 of accuracy.The outcomes of the current study can be applied to develop a smart review ranking system for Facebook product pages.

Kristal guava is one of the horticultural commodities that is in demand by the public at large amount and can grow well in Indonesia. The low production of Kristal guava in the off-season is one of the causes of not fulfilling the demand for the fruit. The research was conducted in Semanik Village, Badung, Bali, Indonesia from January to July 2023. This study aimed to increase the growth and production of Kristal guava in the off-season through fertilization with probiotic fertilizer and pruning. This experiment used a factorial Randomized Block Design consisting of 2 factors and 3 replications. The first factor was fertilization with probiotic fertilizer consisting of 4 concentration levels, i.e., control (C0), 10% (C1), 20% (C2) and 30% (C3). While the second factor was pruning, namely: Pt (no pruning) and Pl (pruning 2-3 segments of twig ends + dead twigs + twigs infested with pests). The results showed that the interaction between fertilization with probiotic fertilizer and pruning had no significant effect in off-season production of Kristal guava. The 30% probiotic fertilizer concentration (C3) was able to increase the growth as indicated by the variable number of new shoots per tree (2.17 shoots) and the number of leaves of new shoots per tree (2.67 leaves) and the off-season production of Kristal guava, reflected in the increase in the number of flowers formed per tree (103.50 flowers), the number of harvested fruits (3.50 fruits) and the weight per fruit (49.72 g) or an increase of 93.46%; 40% and 114.31%, respectively, compared to C0 which was 53.50 flowers; 2.50 fruits and 23.20 g. The Pl treatment increased the growth as indicated by the variables of leaf chlorophyll content (69.55 SPAD) and leaf relative water content (59.58%) and the off-season production of Kristal guava as reflected by the number of flowers formed per tree (91.25 flowers), the number of fruits formed per tree (8.83 fruits) and the weight of fruit per tree (163.22 g) or an increase of 39.85%; 103.93% and 123.28%, respectively, compared to Pt which was 65.25 flowers; 4.33 fruits and 73.10 g.
