Authors: Akramova E. G. , Savelyev A. A. , Khamitova R. Ya. , Vlasova E. V.
Published: August 2023

Aim. To identify significant echocardiographic parameters in the screening assessment of long-term outcomes of inferior wall myocardial infarction (MI) with primary percutaneous coronary intervention (PCI) using a logistic regression model.

Material and methods. The study included the examination results of 144 people with inferior wall MI with primary PCI at admission, discharge and 6, 12, 24 months after discharge. Logistic regression analysis to identify screening outcomes of inferior wall MI included 184 variables, including 131 echocardiographic signs. Analysis of variance was performed using the ANOVA Type II method. The model quality was assessed using the likelihood ratio test and the Akaike criterion.

Results. In patients with inferior wall MI and primary PCI, adverse outcomes were observed in 59,7% of cases in the form of repeated myocardial infarction and PCI, coronary artery bypass grafting, the development of stage 2 chronic heart failure, and/or rehospitalizations. For the long-term prognosis of inferior wall MI, in addition to left ventricular ejection fraction, mitral E/A, left atrial volume index and wall motion score index (WMSI), the following echocardiographic predictors were assessed: tricuspid S’ and e’, circumferential strain of the medial level, longitudinal strain of the apical and basal left ventricular levels, longitudinal strain of the segments included in the blood supply area of the circumflex artery.

Conclusion. Echocardiographic parameters using Doppler and speckle-tracking technology have proven to be significant in screening outcomes of acute inferior wall MI with PCI.
Optimality Guarantees for Particle Belief Approximation of POMDPs
Authors: Lim Michael H. , Becker Tyler J. , Kochenderfer Mykel J. , Tomlin Claire J. , Sunberg Zachary N.
Published: August 2023

Partially observable Markov decision processes (POMDPs) provide a flexible representation for real-world decision and control problems. However, POMDPs are notoriously difficult to solve, especially when the state and observation spaces are continuous or hybrid, which is often the case for physical systems. While recent online sampling-based POMDP algorithms that plan with observation likelihood weighting have shown practical effectiveness, a general theory characterizing the approximation error of the particle filtering techniques that these algorithms use has not previously been proposed. Our main contribution is bounding the error between any POMDP and its corresponding finite sample particle belief MDP (PB-MDP) approximation. This fundamental bridge between PB-MDPs and POMDPs allows us to adapt any sampling-based MDP algorithm to a POMDP by solving the corresponding particle belief MDP, thereby extending the convergence guarantees of the MDP algorithm to the POMDP. Practically, this is implemented by using the particle filter belief transition model as the generative model for the MDP solver. While this requires access to the observation density model from the POMDP, it only increases the transition sampling complexity of the MDP solver by a factor of O(C), where C is the number of particles. Thus, when combined with sparse sampling MDP algorithms, this approach can yield algorithms for POMDPs that have no direct theoretical dependence on the size of the state and observation spaces. In addition to our theoretical contribution, we perform five numerical experiments on benchmark POMDPs to demonstrate that a simple MDP algorithm adapted using PB-MDP approximation, Sparse-PFT, achieves performance competitive with other leading continuous observation POMDP solvers.

Pediatric Myasthenia Gravis
Authors: Tiongson Emmanuelle
Published: August 2023

Abstract:

Pediatric myasthenia gravis (MG) is a relatively rare, but very treatable condition. Prognosis in pediatric myasthenia gravis is favorable for minimal manifestation status (MMS) or remission when compared to adults. Ocular only presentations are more common, though severe refractory generalized MG presentations also occur. An observational examination is key to the diagnosis and follow-up of pediatric MG patients in the clinic setting. Treatment options are limited by side effect and growth considerations, as well as lack of approved MG medications in the pediatric population. Multidisciplinary care should be considered for pediatric MG, similar to other neuromuscular conditions seen in specialty care settings.
Promising Antigen-specific Immunotherapy for the Treatment of Myasthenia Gravis
Authors: Ntoukaki Eleni , Baltatzidou Vasiliki , Lazaridis Konstantinos
Published: August 2023

Myasthenia gravis (MG) is a T cell-dependent, antibody-mediated, autoimmune disorder with well-established antigenic targets at the neuromuscular junction. MG autoantibodies mainly target the nicotinic acetylcholine receptor (AChR) and especially epitopes located in the extracellular domain of the α1 subunit (α1-ECD). Today, most therapeutic regimens for MG are non-specific and not curative, requiring chronic treatments that are associated with significant side effects. We aim to develop an antigen-specific therapeutic approach, based on reestablishing tolerance towards the AChR, the dominant autoantigen in MG. To this end, we used a soluble mutated form of the human α1-ECD, which incorporates a major fraction of MG autoreactive T cell epitopes and examined the therapeutic efficiency of intravenous administration in a rat experimental autoimmune MG model. We found that repeated intravenous administration of α1-ECD for up to 12 days led to a robust amelioration of disease symptoms in a dose and time-dependent manner. The observed therapeutic effect of α1-ECD was significantly better than the effect of two current mainstay drugs for MG treatment. There were no signs of toxicity in α1-ECD-treated animals and further studies are underway to fully elucidate the immunological mechanism underlying the treatment effect. Taken together, our preclinical data strongly suggest that intravenous administration of α1-ECD may represent an efficacious and safe strategy to treat MG and thus α1-ECD represents a new drug candidate for clinical application in MG.
Photorepair Fluence Response Protocol v1
Authors: Ma Daniel
Published: August 2023

Photorepair light exposures are performed on microorganism samples following UV light exposure (i.e. UV disinfection) to determine microorganism regrowth and repair kinetics. Photorepair is a light-dependent, enzyme mediated DNA repair process in bacteria that may reverse UV-induced DNA damage and decrease UV disinfection efficacy. Previously, photorepair kinetics were determined on a time-basis (i.e. exposure times). However, time-based photorepair determinations are not standardized. A photorepair fluence response protocol was developed here according to a standardized protocol proposed by Bohrerova and Linden (2007). When using this protocol, we request that you cite the original reference.

Published: August 2023

African yam bean seeds condiment is an unpopular nutritive local food seasoning compared to Iru and is mostly produced by natural fermentation. Production with a defined starter culture will give a novel functional condiment with enhanced nutritive values, especially amino acids, to prevent hidden hunger, shorten the fermentation time, and improve product uniformity. The effect of different monoculture bacterial starters and natural fermentation on the amino acids profile of condiments produced from African yam bean seeds was investigated. The result revealed a total of 18 amino acids with glutamic and aspartic acids as the most abundant amino acids in all the samples portions, with a range of values of 9.79-11.44 g/100 g protein and 9.20 -10.67 g/100 g protein respectively. The inoculated samples were rich in all the amino acids quality than un-inoculated. The total amino acid content of the samples was significantly different (p ≤ 0.05). Bacillus amyloliquefacien starter fermented sample had the highest total amino acid value of 95.80 g/100 g protein while Bacillus subtilis fermented and un-inoculated seed portion samples had a total amino acid value of 86.81 g/100g and 74.04 g/100 g protein respectively. The essential amino acids (EAA10) were significantly different (p ≤ 0.05) and were in the range of 35.75-46.32 g/100 g protein with leucine, arginine, lysine, valine, isoleucine and phenylalanine the most abundant in inoculated and un-inoculated samples portions and were more concentrated in inoculated samples. Non-essential amino acids were slightly higher (38.29 - 49.47 g/100 g protein) than the total essential amino acids. The total acidic amino acids varied from 18.99 – 22.11 g/100 g protein and were significantly higher than the basic amino acids (12.88 – 15.95 g/100 g protein). The amino acid content of the Bacillus amyloliquefacien starter fermented sample was better enhanced than the sample fermented with Bacillus subtilis starter. The study concluded that controlled fermented condiments produced with B. amyloliquefacien culture boosted the amino acids value and profile.

Authors: Ali Hassan , El Zubeir Ibtisam
Published: August 2023

The present study was conducted to process and evaluate the chemical composition of ice cream made from camel milk, flavored with vanilla, baobab and papaya fruits. Camel milk, baobab and papaya were examined for chemical composition before the processing. Ice cream samples were made using one level of vanilla (3%) as control and two levels of each baobab and papaya (3% and 5%). Then ice cream samples were packed into plastic cups and stored in a freezer at -18 oC for 8 weeks. The chemical composition was examined every two weeks. The data showed significantly (P<0.05) higher total solids and ash in baobab (5%) ice cream samples, while high fat content was found in vanilla (3%) and papaya (5%). Also, high protein content was found in papaya ice cream samples. It was concluded that processing of ice cream using baobab (3%) and papaya (3%) gives ice cream with good chemical properties. The study recommended processing of ice cream from camel milk adding baobab and papaya fruits. Further studies should be conducted by adding local fruits and other additives to enhance the chemical properties of ice cream from camel milk as functional food.

This study investigated the effect of varietal differences on the chemical and pasting properties of composite wheat-cassava flours produced with blend of wheat and high-quality cassava flour from low postharvest physiologically deteriorated (PPD) cassava roots. Wholesome four varieties of yellow-fleshed low PPD cassava roots and one variety of high PPD cassava root were, peeled, washed, grated, pressed, pulverized, flash dried at 120 °C for 8 minutes, milled with cyclone hammer mill fitted with a screen of 250 µm aperture size, cooled and packed into high density polyethylene bag. The high-quality cassava flours (HQCF) were composited with wheat flour and analyzed for chemical and pasting properties. Data obtained were subjected to analysis of variance (ANOVA) using Statistical Package for Social Sciences (SPSS version 25.0) and significant means were separated applying Duncan multiple range test and Pearson’s correlation was also determined. The results depict that moisture, protein, fat, ash, sugar, starch, dry matter and energy value ranged from 12.45 - 13.10 %, 10.30 - 11.65 %, 0.40 - 3.71 %, 0.58 - 0.62 %, 1.75± - 2.08 %, 70.94 - 74.40 %, 86.90 - 87.55 % and 1464.29 - 1531.66 KJ/kg, respectively. Peak, trough, breakdown, final, setback, peak time and pasting temperature ranged from 180.63 - 247.21 RVU, 95.84 - 129.00 RVU, 83.42 - 118.21 RVU, 139.29 - 253.71 RVU, 83.79 - 124.71 RVU, 5.90 - 6.17 min and 69.00 - 73.48 °C, respectively. Considering the relatively high dry matter content, energy value, peak viscosity, low breakdown viscosity and pasting time, flour blends C-C1368-W and C-C0593-W prepared with HQCFs from IITA-TMS-IBA-011368 and IITA-TMS-IBA-070593 cassava varieties could find application in baking and confectionery industry.
Impact of extraction method on alkaloid content and antioxidant activity of Matricaria pubescens
Authors: Metrouh-Amir Hassiba , Amir Nadir
Published: August 2023

Matricaria pubescens is a medicinal plant much appreciated by the people of the Saharan regions and widely used to treat many diseases. The present study was devoted to evaluate the effect of extraction technique, pH and nature of solvent on alkaloid content and antioxidant activity of M. pubescens. Alkaloid extraction was carried out by applying two techniques, maceration extraction and Soxhlet extraction, using several solvents at different pH (alkaline chloroform, acid methanol, neutral methanol and neutral ethanol). In the present study, the antioxidant activity of the alkaloid extracts of M. pubescens was evaluated using ferric reducing power, molybdate reducing power, DPPH radical scavenging activity, ABTS radical scavenging activity, β-carotene bleaching assay, hydroxyl radical scavenging activity (assessed by deoxyribose assay and HOSC assay) and oxygen radical absorbance capacity (ORAC). The obtained results show that the extraction rates obtained and the antioxidant activities of alkaloid extracts were affected by the extraction technique, pH and the solvent used. The highest extraction rates were obtained with the ethanolic neutral (Soxhlet) and methanolic acidified (maceration) extracts. The alkaloid extracts of M. pubescens exerted a reducing activity of ferric and molybdate ions. They also showed significant radical scavenger activity against DPPH, ABTS, hydroxyl, and peroxyl radicals. This significant wealth of alkaloids and these various antioxidant activities could justify the traditional use of M. pubescens.
Fiscal Rules and Federal Capacity in American Fiscal History: Lessons for Europe?
Authors: Georgiou Christakis
Published: August 2023

Recent comparative fiscal federalism work has noted how the US displays a mix of substantial federal capacity and no federal fiscal rules for sub-federal units as opposed to the EU’s mix of regulation and lack of capacity. The difference is explained by the lack of federal capacity in the EU case, which presumably creates a need for regulation. However, these studies are cross-sectional. This carries the obvious drawback of abstracting the actual political and historical processes that have given rise to the respective mixes of regulation and capacity in the two polities. In this article, I trace the historical process by which the specific mix of no rules and capacity became entrenched in the US in the second half of the 20th century and ask whether that political-economic history has any lessons for the EU today.
Socio‐Occupational Integration of Chinese Migrant Women in Andalusia Through Spanish Language Training
Authors: Cores-Bilbao Esther , Camacho-Díaz Mariló
Published: August 2023

The present article explores the perceived role of work and proficiency in a second or additional language(s) among a group of Chinese migrant women learning Spanish in Andalusia. The enrolment of Chinese adult learners in language upgrading programmes in immersion contexts is relatively low, as Chinese expatriates tend to establish close‐knit, socio‐culturally elusive communities whose interactions with local residents are often limited to work‐related purposes. The distinctiveness of this ethnographic work lies in its focus on women who, having resided in southern Spain for extended periods and aiming to emancipate themselves from male family referents, have only recently sought greater inclusion in Spanish society. Through in‐depth interviews, these women’s prospects for professional advancement and self‐employment are also identified, albeit subsidiarily, among the reasons for pursuing higher levels of linguistic competence. The results point to a desire to develop higher levels of competence in linguistic, civic, and socio‐cultural literacies to expand their social networks and engage more actively in the communities where they currently live. Avoiding vulnerability to potential deception in the workplace and administrative settings, coupled with the need to participate in better‐informed decision‐making at the personal level, is also highlighted as contributory factors to their willingness to pursue multiliteracies in linguistic, civic, and occupational areas. The conclusions point to a mismatch between the training aspirations of these women and the curricula of the courses available to them within a Chinese educational organisation, whose focus lies almost entirely on the development and reinforcement of linguistic skills.

Authors: Sundararajan Swathi , Afle Gauri Mayank
Published: August 2023

Background: Assessing respiratory muscle strength is an important aspect for clinical practice as well as in research. Multiple factors such as health status of an individual, level of physical fitness and postsurgical recovery of an individual have an influence on respiratory biomechanics. Respiratory muscle strength is determined by measuring maximal inspiratory pressure and maximal expiratory pressure. There is a need for a cost effective, portable, easy to build device specifically to estimate respiratory muscle strength. There is insufficient literature regarding the resources used to determine the respiratory muscle strength testing in children, hence this study aims to establish the reliability and validity of low cost pressure gauge manometer which could be a useful tool in measuring respiratory muscle strength in children.
Methods: A capsule sensing pressure gauge constructed according to the American thoracic society guidelines with a calibration of pressure between −200 cmH2O to +200 cmH2O. It was used to measure the respiratory muscle strength. The study was conducted on 300 healthy children.
Results: SPSS software was used for statistical analysis. Reliability of 0.92 and 0.97 was obtained for MIP and MEP respectively by test retest method. Construct validity index showed a validity score of 0.8 for MIP and MEP.
Conclusions: The results indicate that the low cost pressure gauge manometer can be used as a reliable and valid device to measure respiratory muscle strength in children.
„Strzeż się zamiarów prze-pisanych szczelnie…”. Jeden czy dwa wiersze Norwida?
Authors: Chlebowski Piotr
Published: August 2023

Artykuł mający charakter edytorskiej analizy, odnosi się do dwóch przekazów Przyjacielowi-poecie oraz Teofilowi, który w tradycji uznawany był dotąd za jeden tekst, jeden utwór poetycki Norwida. Ten pierwszy, Przyjacielowi-poecie, miał stanowić przeredagowaną samowolnie przez Teofila Lenartowicza, ze zmienionym tytułem, uszczuploną wersję (z mniejszą liczbą wersów: uszczuplony o 28 w stosunku do tego drugiego przekazu) przekazu drugiego, Teofilowi, nazywanego właściwym lub pełnym. Efektem porównania obu przekazów oraz danych historycznych z nimi związanych jest teza, uznająca je za różne teksty poetyckie, co w konsekwencji prowadzi do wniosku o traktowaniu ich jako dwóch osobnych wierszy Norwida. Utwór Przyjacielowi-poecie ma charakter ogólny, wyabstrahowany z personalnych konkretyzacji. Jeśli już się one tu przebijają na pozycje prymarne, to można byłoby je łączyć nawet z samym Norwidem. W tym sensie wiersz miałby charakter autoteliczny. Ten drugi, Teofilowi – o czym w ogromnym stopniu decyduje tytuł – stawia przed odbiorcą konkretną postać, znanego poetę i przyjaciela Norwida, stawia z całym kontekstem związanym z jego biografią i jego twórczością, zwłaszcza lat 1854-1855.

The purpose of the research paper is to assess the approaches to appraisal of employee work performance in enterprises. The empirical research in the questionnaire survey focused on the factors influencing employee work performance. The research was conducted in the second half-year 2022 on the sample of 260 respondents from enterprises operating in Slovakia. Two hypotheses were established and a research model was created. Methods used in the paper include: analysis, questionnaire survey, and synthesis. To evaluate the questionnaire survey and verify hypotheses, contingency tables, descriptive statistics methods, correlation, and regression were applied. Although the results of statistical verification of hypotheses did not prove the existence of statistically significant relationship, in one case there were 8 out of 18 relationships; thus there is some relationship. Results indicate which factors are important in companies in achieving employee work performance.The statistical verification of hypotheses by correlation and the regression model proved the influence of the business sector on employee work performance appraisal (eight significant relationships). Further research is necessary for the generalisation in this area.The importance of the company’s most important asset, i.e. human capital is corroborated by means of statistical methods used in the paper. Moreover, the importance of structural capital is emphasized. The originality of the paper is in a creative application of statistical methods as well as in establishing five features characteristic of the approach to work performance in Slovakia’s enterprises.

Authors: Mishra Atul , Mishra Alok
Published: August 2023

The task of identifying and analyzing Reduplication Multiword Expressions (RMWEs) in Natural Language Processing (NLP) involves extracting repeated words from various text forms and classifying them into Onomatopoeic, non-Onomatopoeic, partial, or semantic types. With the increasing use of low-resource languages in news, opinions, comments, hashtags, reviews, posts, and journals, this study proposes a machine learning-based RMWE identification method for Hindi text. The method employs linguistic patterns and statistical data, along with a proposed threshold boundary detection in statistical filtering. The Jaccard distance of dissimilarity and Sorensen Dice Coefficient of Similarity are used for semantic relation analysis. The proposed approach was evaluated using the publicly available Hindi corpus from IITB, measuring performance between two consecutive thresholds with the lowest error and highest recall. This study proposes an effective method for Indian computational linguistics, with experimental results highlighting its viability and utility, and providing a blueprint for current procedures.

Published: August 2023

The hotel industry is a significant sector for Indonesian economic growth. Nowadays, cloud computing is bringing much potential for hotels to increase their competitive advantage, specifically in facilitating Information Systems (IS). However, we found still limited study that investigates cloud-based IS in accounting functions. Therefore, this study aims to analyze 1) the impact of the human aspect in determining cloud performance, 2) the impact of cloud performance on the relative advantage and compatibility of cloud-based Accounting Information Systems (AIS) in the hotel industry, and 3) the impact of its relative advantage and compatibility on cloud-based AIS quality. Using purposive sampling, the data was collected from accounting and/or information manager hotels in North Sumatra, Indonesia. The collected data were analyzed using variance-based Structural Equation Modeling (SEM). We found that human, cloud performance, and technology adaptability are the critical antecedents of cloud-based AIS quality in the hotel industry. Hotel leaders should consider user computer-self efficacy and cloud-AIS alignment design while developing and integrating cloud-based AIS into their general system.

The Challenge of South Africa to Reduce Its High Unemployment
Authors: Mellet Andre
Published: August 2023

The unemployment rate in South Africa has been in excess of 20% for many years. Various questions can be asked about policies and probable solutions to reduce unemployment. What is wrong with South African macroeconomic policies or is it rather what is wrong with economic and political coordination of policies? What is the probability of millions of South African inhabitants to rise out of poverty? Certain policies for example ASGISA have good foundations, but the main problem in South Africa is two-fold. Firstly, sustained high growth of 6% will not be achieved as long as economic principles are overshadowed by the political agenda of transformation in South Africa.Â  Secondly, fundamental changes are needed in the South African economy and need urgent attention, but the lack of management at all levels in government to address the structural problems, handicap such changes.
An Empirical Analysis of the Impact of Foreign Direct Investment on Economic Activity of India
Authors: Jayaraj R. , Gupta Sumeet
Published: August 2023

FDI in India has - in a lot of ways - enabled India to achieve a certain degree of financial stability, growth and development. This money has allowed India to focus on the areas that may have needed economic attention, and address the various problems that continue to challenge the country. India launched a series of progressive economic liberalization policies to overcome the structural defects that has caused the economic crisis in 1991. With these policy changes, foreign direct investment (FDI) into India has increased rapidly since 1992. Foreign direct investment to India increased from a mere $97 million in 1990-91 to $5,526 million in 2004-05 because of institutional restructuring. The study indicates the co-movement and converging behaviour between the two the movement of FDI and GDP. FDI is not closely following the GDP in the initial period but after the year of 1992 it closely converges with movement in the FDI. The FDI inflows attained its peak in the mid of 2007 and the GDP also responded quickly to it and attained its all time hike. The results shows that FDI did not Granger cause GDP but interestingly GDP has Granger cause on FDI. This result shows the inter-relationship between these two variables. An increased domestic economic activity will attract foreign investors to invest in India. Because of the huge population, increased domestic production in various industries, infrastructural facilities, large domestic market would attract foreign investors.
Globalization of Finance: Indiaâ€™s Experience of Capital Flows
Authors: Nanda Paramjit , Kaur Sandeep
Published: August 2023

Globalization of finance measured in terms of capital account liberalization has been viewed by many economists as an important component of the overall opening up of global trade and financial markets especially in recent years. It is in this context, paper seeks to analyse issue of CAC in India. Study reveals that capital account surplus is mainly accounted for by non-debt creating foreign investment inflows. Foreign investment and banking balance accounted 80 percent of surplus in capital account. All the components of capital account (except banking capital) witnessed decrease in inflows to outflows ratio during post-CAC period. Banking capital experienced rapid increase in inflows/outflows ratio due to rapid increase in NRIs deposits. Regarding impact of capital account balance on Indian economy, on the positive side, capital account balance significantly reduced inflation and external debt to GDP ratio but on the negative side failed to reduce fiscal deficit and increase in industrial production. RBI should direct more calibrated distribution of bank credit in favour of al productive sectors to increase overall investment in the country. So that capital account surplus can be managed.
The Worldwide Expansion of Education the Past Half-Century and its Impact upon the Global Economy
Authors: Wolhuter C. C.
Published: August 2023

The past half-century has been witness to the largest education expansion drive in human history; as a worldwide education expansion project played itself out.Â  This expansion has taken up a significant proportion of resources of nations.Â  In the case of the developing countries education is almost invariably the biggest item on governmentâ€™s expenditure budgets.Â  In the case of the United States of America (USA) federal funds allocated to education rose tenfold in the thirty year period 1970 to 2000, from US$ 9.2 billion to US$ 90.6 billion. One major motivation for this concentrated employment of resources is the belief that investment in education promotes, or indeed is a sine qua non for economic growth.Â  Testing this supposed relation, especially in the contemporary era, is therefore timely.Â  The aim of this article is to investigate the co-variation betweenÂ  education effort (measured in terms of enrollment ratios) and economic performance (measured by per capita gross domestic product) of the various countries of the world, almost half a century ago; at the outset of the massive education expansion drive which took off during the second half of the twentieth century.Â
Student Learning With Technology From an Instructional Economic Perspective: A Case Study
Authors: Chou Pao-Nan
Published: August 2023

The current study employed two case studies, which were conducted in Taiwan, to explain the benefits of old technologies from an instructional economic perspective. The findings yielded from two case studies showed that old (inexpensive investment) and new technology (expensive investment) could equally enhance studentsâ€™ learning performances. Instructors may re-think the value of old technologies at classrooms based on economic theories.
From Parents to Children: Intergenerational Transfers---A Case Study
Authors: Kumar Suchitra S
Published: August 2023

This paper attempts to test whether women systematically get less education than their male siblings and is based on data drawn from a survey in Mumbai of 200 women and their male siblings.Â  The regression models used explicitly take account of human capital factors. The results show that for similar levels of academic performances, family background etc; women systematically get less parental investment in their education than their male siblings. Thus, pure human capital models of labour market are inadequate to account for the gender perspective. Any analysis of the labour market must hence incorporate gender as an explicit variable.
Role of Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) in Rural Asset Creation in India â€“An Analysis
Authors: Dhananjaya K , Prathibha M.S
Published: August 2023

The MGNREGA ranks among the most powerful initiatives ever undertaken for transformation of rural livelihoods in India. The unprecedented commitment of financial resources is matched only by its imaginative architecture that promises a radically fresh programme of rural development. However, for MGNREGA to realise its potential, it must focus on raising the productivity of agriculture in Indiaâ€™s most backward regions. This can then lead further to the creation of allied livelihoods on the foundation of water security. This is also the only way we can envision a decline in the size of the work guarantee over time, as public investment under MGNREGA leads to higher rural incomes, that in turn spurs private investment and greater incomes and employment.

Economic development of a country depends very much on the availability of its infrastructural facilities particularly the development of sectors such as Agriculture, Industry and Service Sectors. An economyâ€™s infrastructure is more conveniently divided into two parts Physical Infrastructure and Social Infrastructure. Physical Infrastructure is directly concerned with the needs of such production sectors as agriculture, industry & trade. The physical infrastructure, include such services such as power, irrigation, transport telecommunication. On the other hand, social infrastructure comprising education, health and medical care, nutrition, housing and water supply which is instrumental in contributing to substantial improvements in human development, which in turn, initiate and accelerate economic development.Â Â Â Â Â  Human Development is the process of widening peopleâ€™s choices and their level of well-being. The choices change over time and differ among societies according to their stage of developmentThe three essential choices for people are - to lead a long and healthy life, to acquire knowledge and to have access to the resources needed for a decent standard of living. If these choices are not available, many other opportunities remain inaccessible. Other choices, highly valued by many people include political, economic and social freedom, access to opportunities for being creative and productive and enjoying self-respect and guaranteed human rights
