Published: August 2020

Hyper emesis gravidarum is a rare obstetrical problem with incidence of 2 to 3% of pregnant women experience deliveries. Various demographic factors have been hypothesized as contributing facors for hyper emesis gravidarum. These include occupational status, maternal age, parity and inter pregnancy interval. Hyperemesisi gravidarum is because of result of an adaptation to the hormonal milieu. Although studies have identified many adverse pregnancy outcome such as low birth weight, intra uterine growth retardation etc. In this study Bilwadi Lehyam with Pathya Ahara has been evaluated for its efficacy in the management of Garbhini Chardi.

Published: August 2020

In present scenario due to the sedentary lifestyle, diabetes mellitus has become common disease. Diabetic foot ulcer is a complication of diabetes mellitus which is the leading cause of lower limb amputations. It occurs in 15% of all patient with diabetes mellitus and precedes 84% of patients with diabetic foot ulcer which needs lower leg amputation. The management of diabetic foot ulcer requires blood sugar control, debridement, advanced dressing and offloading modalities. In Ayurvedic literature, Acharya Sushruta has described sixty treatment modalities, He has given more importance to Vranashodhana and Ropana. Acharya Vagbhatta has explained that Vranas which are caused by Madhumeha can be treated with Aragwadhadigana Dravyas, hence in the present study for Vrana Shodhanartha Prakshalana with Aragwadhadi Qwatha and Vrana Dhoopana by Guggulu, Nimba Choorna, Haridra, Jatyadi Ghrita were selected and for Vrana Ropanartha Jatyadi Taila was selected.
A clinical study on Mulaka Kshara in the management of Moothrashmari (Renal Calculi)
Authors: Kembhavi Aakash , Kaushik Jitender
Published: August 2020

According to Ayurveda, Moothrashmari is a combined terminology which constitutes Moothra + Ashmari. Ashmari comprises of two words, i.e. Ashma and Ari, where Ari refers to the pain as given by an enemy, pain due to Moothrashmari is known as worse than that of labour pain. This disease is dreadful and hence considered one of the Mahagada by Sushruta, may be owing to its potentiality to disturb the anatomy and physiology of urinary system. Acc to modern the word renal calculus is derived from Latin language, according to which Renes means kidneys and calculi, means pebble or stone. It is a solid concretion or crystal aggregation formed in the kidneys from dietary minerals in the urine. Urinary stones are typically classified by their location in the kidney (nephrolithiasis), ureter (ureterolithiasis) or urinary bladder (systolithiasis) or by their chemical composition (calcium containing, uric acid, struvite or other compound). It is estimated that at least 10% of the industrial population of the world is affected by urinary tract stone. Thus the disease is a wide spread as it is old, particularly in countries with dry and hot climate. In India, approximately 5-7 million patients suffer from stone disease and at least 1/1000 of Indian population needs hospitalization due to this disease. Kshara is having Lekhana, Bhedana, Pachana, Shodhana and Tridoshaghna properties. Thus study “Effect of Mulakakshara in the management of the Moothrashmari (renal calculi)” is undertaken.
Shimbi Dhanya (pulses) as Ayurvedic food supplement for calcium deficiency
Authors: K.S. Dr. Athira , Tripathy Dr. T.B. , Sharma Dr. Swathy , M.S. Dr. Harisankar
Published: August 2020

Ahara (food) is an important tool in Ayurveda. Ahara itself acts as an Aushadha (medicine). Shimbidhanya Varga (pulses) in daily diet has an important role in maintaining strength of Asthi Dhatu. Asthi Dhatu can be anatomically correlated to bones and teeth of body, 98% of bones composed of calcium. So calcium deficiency may directly proportional to Asthi Dhatu Kshaya. Shimbi Dhanya Varga (pulses) is rich in Proteins, Calcium, Phospherus and Magnesium. Mudga (green gram), Masha (black gram), Soya Bean etc. are coming under Shimbi Dhanya Varga has 124mg, 154mg, 240mg of calcium content respectively per 100gm. It will satisfy RDA of calcium in diet. Among Indian population aged 30 to 60 years had low calcium with high prevalence of osteopenia (52%) and osteoporosis (29%). This made the community to use of calcium tablets with or without physicians advice. So incomplete absorption, high cost and later side effects affects community health. So promote and educate useful ways of intake of calcium to human body just through daily diet and made it part of community health care programmes.

Authors: Bil Damián
Published: August 2020

Este trabajo pretende analizar someramente un evento de lo que consideramos la crisis estructural de la zona euro: el conflicto independentista en Cataluña (2017). Nos concentraremos en el análisis del fenómeno económico, entendiéndolo como consecuencia de la crisis del capital de largo plazo. A partir del análisis de variables económicas agregadas —en particular referentes a la producción e industria, finanzas públicas e ingreso de hogares y de trabajadores— y de la organización productiva, y mediante el análisis de la relación de Cataluña con el resto del España y de la eurozona, intentaremos discutir la noción de una supuesta “opresión nacional” en la perspectiva de las transformaciones ocurridas en esta región luego de la crisis de 2008-09.

Published: August 2020

The Battle of Britain is one of the most important military events of the Second World War. Different approaches have been used to study it and understand the rationale behind Britain’s and Nazi Germany’s strategy. However, the use of warfare concepts, such as centers of gravity and its contemporary meaning, to scrutinize the planning and prosecution of the battle have not been as prolific. This article aims to contribute to the debate by maintaining that the concept of Centers of Gravity provides an advantageous framework that facilitates the understanding of the mindset and development of the battle in terms of critical capabilities, requirements, and vulnerabilities required to win.

We study the role of disorder in the force constants distribution on the acoustical and optical phonons in amorphous graphene. It is shown that for a sufficient strength of disorder the boson peak appears in the density of states. With increasing strength of disorder, the peak moves to low frequencies together with Yung modulus. For sufficiently small disorder we have the Van-Hove singularities in the vibration density of states. With increasing disorder, these singularities transform together to one boson peak. The first disappears optical phonons then the acoustical one. The same investigation was done for flexural modes. We show that these modes disappear in disorder in already weak perturbations and transforms to phonons.

Multi-walled carbon nanotubes were subjucted to irradiation of argon ions and electron and consequent annealing in inert ambient. Transmission electron microscopy and X-ray photoelectron spectroscopy have been used to study the structure tranformation and chemical conditions of nanotubes. It is shown that irradiation with argon ions and electrons leads to the formation of defects in the structure of carbon nanotubes and a change in the interlayer distance in the walls of nanotubes. Also the fixation of functional oxygen-containing groups on their surface is observed. Annealing of irradiated nanotubes in an inert atmosphere leads to a partial restoration of the structure of MWCNT. In this case, upon irradiation with argon ions, the nanotube structure is restored, and the oxygen concentration decreases. After the annealing of MWCNT irradiated with electrons, multi-vacancy defects are observed on the outer graphene layers. These large defects are the attachment points for functional groups containing a carbon-oxygen double bond (C = O). Binding energies and optimized geometry for various configurations of vacancy clusters in the graphene plane were obtained using calculations performed within the framework of the density functional theory.

Published: August 2020

Using the method of molecular dynamics, it was shown that hydrogen fluoride molecules inside single-wall carbon nanotubes with a diameter D<0.85 nm form flat zigzag chains of hydrogen bonds F–H∙ ∙ ∙F–H∙ ∙ ∙F–H∙ ∙ ∙ . The chains structurally closest to the chain of hydrogen bonds of hydroxyl groups OH form hydrogen fluoride molecules inside nanotubes with a chirality index (6,6) and (10,0). In such open nanotubes with narrowed edges, hydrogen bond chains (FH) _N can completely fill their internal cavity forming a structure that is resistant to thermal fluctuations in a wide temperature range. The chains can have stationary orientation defects localized on 3-4 chain links separating parts of the chain having the opposite directions of FH molecules. The molecular complexes (FH)_N∈CNT(6,6) and (FH)_N∈CNT(10,0) can play the role of proton-conducting nanowires, in which the outer nanotube serves as a external winding (insulation) that protects and stabilizes the inner proton-conducting chain (FH)_N.

Methods of high-frequency electron paramagnetic resonance (EPR), electron spin echo (ESE), and optically detectable magnetic resonance (ODMR) were used to study the unique properties of nitrogen-vacancy defects (nitrogen-vacancy NV center) in diamond in strong magnetic fields. It has been shown that in strong magnetic fields (3 to 5 T), an effective optically-induced alignment of populations of spin levels occurs, with filling of the MS=0 level and emptying of the MS=1 levels, which allowed to observe ODMR via variations of the photoluminescence intensity, reaching 10% at resonance. It has been demonstrated that this efficiency in high magnetic fields is of the same order as that in zero and low magnetic fields. The samples were preliminarily studied by ODMR in zero magnetic fields, which made it possible to accurately determine the main parameters of the fine structure and hyperfine interactions with nitrogen nuclei, as well as dipole-dipole interactions between the NV center and deep nitrogen donors (nitrogen atom replacing carbon, N0). In the spectra of high-frequency ODMR, hyperfine interactions with the nearest carbon atoms (13C isotope) were observed, which opens up possibilities for optical measurements of the processes of dynamic nuclear polarization of carbon in strong magnetic fields. Narrow ODMR lines in high magnetic fields are supposed to be used to measure these fields with submicron spatial resolution. A new method for detecting ODMR of NV centers with modulation of the microwave frequency has been developed, which simplifies the technique of measuring high magnetic fields. A significant increase in the intensity of the ODMR signal at orientation of the magnetic field along the symmetry axis of NV center was demonstrated.

Published: August 2020

BACKGROUND

The outbreak of COVID-19 has dominated headlines worldwide. The number of infections has continued to rise and had reached 30,000 worldwide at the time this paper was written. Because of the high risk of nosocomial transmission, medical health care workers may be experiencing substantial psychological stress. This descriptive study aimed to identify psychosocial effects on hospital staff associated with working in a hospital environment during the COVID-19 outbreak.

OBJECTIVE

Our survey participants included 57 frontline clinicians working at Wuhan First Hospital and 157 medical students working at Jiangsu Provincial People’s Hospital during the COVID-19 outbreak. The questionnaire we adopted included questions regarding the participants’ personal well-being, sociodemographic characteristics, and psychological status.

METHODS

57 frontline clinicians working in Wuhan First Hospital and 157 medical training students working in Jiangsu Provincial Peoples Hospital during this outbreak participated in our survey. The questionnaire we adopted included questions regarding the participants’ personal well-being, sociodemographic characteristics and the psychological status.

RESULTS

The COVID-19 outbreak had psychological impacts both on formal workers and medical students. The psychological effects included sleep disorders, anxiety, and depression. There was no significant difference between the group of formal workers and medical students (P=.85), and more than 50% (30/54, 56%, vs. 83/157, 52.9%) of the respondents reported pandemic-related mental disorders.

CONCLUSIONS

Our study indicates that the high risk of SARS-CoV-2 exposure caused substantial psychological stress among health care workers. This finding emphasizes the need to promote psychological crisis intervention for medical personnel during this epidemic.
Performance of Digital Contact Tracing Tools for COVID-19 Response in Singapore: Cross-Sectional Study (Preprint)
Authors: Huang Zhilian , Guo Huiling , Lee Yee-Mun , Ho Eu Chin , Ang Hou , Chow Angela
Published: August 2020

BACKGROUND

Effective contact tracing is labor intensive and time sensitive during the COVID-19 pandemic, but also essential in the absence of effective treatment and vaccines. Singapore launched the first Bluetooth-based contact tracing app—TraceTogether—in March 2020 to augment Singapore’s contact tracing capabilities.

OBJECTIVE

This study aims to compare the performance of the contact tracing app—TraceTogether—with that of a wearable tag-based real-time locating system (RTLS) and to validate them against the electronic medical records at the National Centre for Infectious Diseases (NCID), the national referral center for COVID-19 screening.

METHODS

All patients and physicians in the NCID screening center were issued RTLS tags (CADI Scientific) for contact tracing. In total, 18 physicians were deployed to the NCID screening center from May 10 to May 20, 2020. The physicians activated the TraceTogether app (version 1.6; GovTech) on their smartphones during shifts and urged their patients to use the app. We compared patient contacts identified by TraceTogether and those identified by RTLS tags within the NCID vicinity during physicians’ 10-day posting. We also validated both digital contact tracing tools by verifying the physician-patient contacts with the electronic medical records of 156 patients who attended the NCID screening center over a 24-hour time frame within the study period.

RESULTS

RTLS tags had a high sensitivity of 95.3% for detecting patient contacts identified either by the system or TraceTogether while TraceTogether had an overall sensitivity of 6.5% and performed significantly better on Android phones than iPhones (Android: 9.7%, iPhone: 2.7%; P<.001). When validated against the electronic medical records, RTLS tags had a sensitivity of 96.9% and specificity of 83.1%, while TraceTogether only detected 2 patient contacts with physicians who did not attend to them.

CONCLUSIONS

TraceTogether had a much lower sensitivity than RTLS tags for identifying patient contacts in a clinical setting. Although the tag-based RTLS performed well for contact tracing in a clinical setting, its implementation in the community would be more challenging than TraceTogether. Given the uncertainty of the adoption and capabilities of contact tracing apps, policy makers should be cautioned against overreliance on such apps for contact tracing. Nonetheless, leveraging technology to augment conventional manual contact tracing is a necessary move for returning some normalcy to life during the long haul of the COVID-19 pandemic.

Published: August 2020

Objective: The medicinal plants have been using to treat ailments since ancient times. The recent advances in science and technology impel humans to evaluate medicinal plants therapeutic efficiency and isolation of bioactive compounds in pure forms before their use in development of new drugs and their derivatives. But even now, abundant medicinal plants unevaluated scientifically. The current study was aimed to explore phytochemical constituents, antioxidant and hepatoprotective activities of Actiniopteris radiata root parts.

Methods: Standard procedures have been used to perform phytochemical analysis. Antioxidant activity was carried using In vitro methods on superoxide, hydroxyl, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals. Hepatoprotective activity was studied by paracetamol-induced liver toxicity on WISTAR albino rats. The parameters assessed were Aspartate aminotransferase (SGOT/AST), Alanine aminotransferase (SGPT/ALT), alkaline phosphatase (ALP) and total bilirubin levels.

Results: The tested extracts (hexane, ethyl acetate, and hydro-alcoholic) possess biologically active compounds such as sterols, terpenoids, glycosides, phenolics, alkaloids, flavonoids. The hydro-alcoholic extract has more phenolic contents (24.28±0.3) and flavonoid contents (22.68±0.6). The extracts showed dose dependent activity on tested free radicals and extracts showed more percentage inhibition at 320µg. The hydro-alcoholic extract showed more percentage inhibition i.e. 71.00±2.08 on DPPH free radical, 79.67±1.20 on hydroxyl free radical and 80.33±1.20 on superoxide free radical. As antioxidant activity of hexane and ethyl acetate extracts was less and they also showed less percentage protection on liver toxicity, hydro-alcoholic extract showed more percentage protection on biomedical enzyme levels of liver toxicity at high concentration i.e., 400 mg/kg b.w. The percentage protection on the enhancement of AST (SGOT), ALT (SGPT), ALP, and total bilirubin levels were 82.24%, 82.14%, 84.18%, and 82.85% are significant (P<0.01) as Liv52 shown percentage protection on the enhancement of Aspartate aminotransferase (SGOT), alanine aminotransferase (SGPT), Alkaline phosphatase (ALP) and total bilirubin levels were 93.58%, 92.83%, 94.67% and 93.57%.

Conclusion: The current study was aimed to explore phytochemical constituents, antioxidant and hepatoprotective activities of Actiniopteris radiata root parts extracts. The outcome of the current research results provides scientific evidence of the traditional usage of Actiniopteris radiata.

Drugi deo rada posvećen je analizi bilateralnog sporazuma između Srbije i Mađarske u oblasti manjinskog pitanja koji, iako nema obavezujući karakter, predstavlja važan međunarodno-pravni okvir za ostvarenje i zaštitu prava nacionalnih manjina. Istaknuta je važnost regulisanja položaja i prava manjina u cilju unapređenja interetničkih i međudržavnih odnosa, političke stabilnosti i ekonomskog prosperiteta celog regiona.
NOVE KLASNE BORBE U FRANCUSKOJ: SLUČAJ „ŽUTIH PRSLUKA”
Authors: Mladenovic Ivica
Published: August 2020

Jedanaestoro mrtvih, preko četiri hiljade lakše i više od stotinu teško povređenih (od čega sedamnaest izbijenog oka i četiri pokidane ruke): ovo je dosadašnji crni bilans represije nad „Žutim prslucima”. Francuska ne pamti ovako dramatičnu društveno-političku situaciju – izazvanu unutrašnjim rascepima – još od ubistva alžirskih studenata 1961. Čak je i Evropski parlament, 14. februara 2019. godine, osudio nesrazmernu upotrebu sile i korišćenje, u ostatku Evrope inače zabranjenih, GLI-F4 granata za razbijanje demonstracija, dok je UN, kada je reč o policijskom nasilju, Francusku svrstao u isti rang sa Sudanom i Zimbabveom. O situaciji u zemlji najslikovitije možda govori izvođenje vojske na ulice tokom tzv. akta XIX „Žutih prsluka”, u subotu 23. marta 2019. godine. Ovaj rad nudi odgovore na nekoliko pitanja: Da li je ovaj specifičan pokret moguće tumačiti u svetlu novih klasnih rascepa u Francuskoj, i na koji se on način uklapa u Marksov koncept klasne borbe? Koje su socijalne grupe koje čine njegovo jezgro i po čemu se one razlikuju od tradicionalnih klasa? U kojim socijalnim grupama nalazimo najveću podršku metodama borbe ovog pokreta? Koje su njegova ključna svojstva i po čemu se razlikuje u odnosu na prethodne socijalne pokrete u Francuskoj, kao i, generalno, savremene društvene pokrete u Evropi? Kakva je politička artikulacija i politički potencijal „Žutih prsluka”?
MODELI DNEVNIH NOVINA U 21. VEKU KRIZA I STRATEGIJA OPSTANKA – PRIMER SRBIJE
Authors: Penezic Slobodan
Published: August 2020

Tekst predstavlja sublimaciju dela zaključaka do kojih je autor došao tokom pripreme doktorske disertacije. Reč je o nalazima višegodišnjeg istraživanja, teorijskog i empirijskog karaktera, koji nude konkretan uvid u stanje u svetu medija i novinarstva, posmatran kroz koordinate najfrekventnijih tema u toj oblasti. Rezultat je analize realizovane iz ugla onog dela medijske industrije (dnevne novine) koji je na posebnom udaru izazova vremena, te su u tom polju najvidljiviji i efekti, o kojima se, pak, svakodnevno ćuti, a čije posledice se iz različitih razloga mistifikuju.
Predmet istraživanja je odnos uređivanja i poslovanja, a krajnji cilj formulisanja optimalnog modela rada medija danas, koji bi omogućio stabilnost pre svega tih medija čiji opstanak je najviše ugrožen. S tim u vezi, ispitivana je i dokazana generalna hipoteza, koja ukazuje na to da je formulisanje uspešnog modela za dugoročnu poslovnu stabilnost medija uslovljeno prevagom pozitivnog uticaja medijskog upravljanja nad negativnim uticajem eksternih faktora po rad medija.
GRAĐANSKI RAT KAO OBLIK UGROŽAVANJA KAPACITETA SISTEMA BEZBEDNOSTI DRŽAVE
Authors: Gacinovic Radoslav
Published: August 2020

Ovaj rad je pokušaj autora da sa političko-pravnog aspekta analizira suštinu, oblike i karakteristike građanskih ratova. Takođe, ovaj rad upozorava da građanski ratovi najdirektnije ugrožavaju kapacitet sistema bezbednosti moderne države. Kao vrsta unutrašnjeg oružanog sukoba, građanski rat ne podleže pravilima međunarodnog ratnog prava, tako da strane koje ga vode ne uživaju status strana u sukobu u smislu ovog prava. Za takve sukobe međunarodno pravo rezerviše samo minimum pravnih pravila koja će biti primenjivana. Razlog je što se ovakav rat vodi unutar države koja, ostvaruje personalnu suprematiju (vrhovni nadzor, vrhovna vlast) nad pobunjenicima, te stoga građanski rat ulazi u krug njene unutrašnje nadležnosti koja isključuje pravo drugim državama da se u njega mešaju. Drugim reči¬ma, legalna vlast takve države je ovlašćena da pribegne oružju kako bi zaštitila postojeći status quo, dok se pobunjenici u svim pravnim sistemima smatraju krivično odgovornim za primenu oružanog nasi¬lja protiv legalne vlasti. Dakle, građanski rat (civil war) je oružani sukob većih razmera koji se vodi unutar jedne države između njenih državljana (građana). Građanski ratovi se nikada ne završavaju kompromisom, tj. oni traju dok jedna od zaraćenih strana ne pobedi ili dok se silom od strane neke moćne države – država ili OUN silom nametne mir.
IZBORI U HRVATSKOJ 2020: KRAJ DVOPARTIZMA?
Authors: Bursac Dejan
Published: August 2020

Od 2000. godine, dva velika politička bloka dominiraju partijskim sistemom Hrvatske: konzervativni, okupljen oko Hrvatske demokratske zajednice, odnosno levo-liberalni, okupljen oko Socijaldemokratske partije. Dinamika odnosa ove dve grupacije ukazuje na to da se osnovni politički rascep nalazi na liniji podele levice i desnice. Treće opcije su s vremena na vreme uspevale da na kratak rok predstave izazov bipartizmu i ostvare relativno dobre izborne rezultate. Međutim, srednjoročno, upliv trećih aktera je do sada uvek bio neuspešan i brzo bi se utapao u dominantnu bipolarnu podelu, te je sistem ostajao stabilno dvopartijski. Tome je značajno doprineo i slab uspeh populističke desnice, budući da je dominantni HDZ, zahvaljujući svom nacionalističkom nasleđu, uspešno pokrivao i taj deo ideološkog spektra, zauzimajući paralelno pozicije etablirane stranke desnog centra i populističko-nacionalističkog pokreta, tako predupređujući razvoj održive antielitističke opcije. Predsednički izbori 2019/2020. godine signalizirali su promenu: po prvi put desni izazivač (u ovom slučaju nezavisni kandidat Miroslav Škoro) uspeva da osvoji preko dvadeset procenata glasova, te efektivno podeli glasove desnice i izazove disrupciju u do tada relativno stabilnom dualnom takmičenju. Škoro je rezultat gradio kako na dugotrajnoj potrazi dela hrvatskih glasača za trećom opcijom, tako i na nizu manjih nacionalističkih i populističkih stranaka i pokreta prisutnih u hrvatskoj politici poslednjih godina. Uspeh na predsedničkim izborima i posebno reakcija njegovih birača, koji se po svoj prilici nisu utopili u bipartijsku podelu u drugom krugu izbora, signalizira promenu dinamike čitavog partijskog sistema, moguće već na parlamentarnim izborima koji će biti održani u julu 2020. godine.
El uso industrial del agua en la cervecería Heineken en Monterrey, México
Authors: Corrales C. Salvador
Published: August 2020

El objetivo es analizar el uso del agua en la industrialización de la cerveza en la ciudad de Monterrey, Nuevo León, México. Esta ciudad se caracteriza por la escasez del recurso que es la materia prima principal para la elaboración de la bebida. Se resume la teoría de la organización industrial y se analizan la producción y la comercialización de la industria para saber cuál es la posición de Heineken en el mercado cervecero nacional. Mediante estadísticas sobre las concesiones de agua, se construyen índices de concentración de varias actividades industriales y se cotejan con el valor agregado industrial bruto para saber cuánto contribuyen éstas al desarrollo económico regional. Entre los principales hallazgos, se puede destacar la baja contribución de la industria cervecera al producto interno bruto regional en comparación con la industria acerera, cuyo consumo de agua supera el promedio regional y nacional para esa actividad industrial, que puede desembocar en conflictos por la administración del agua.
Hermanas olvidadas de “genios” mexicanos: María del Refugio Ponce y María Teresa Lara
Authors: Chibici-Revneanu Claudia
Published: August 2020

Objetivo: recuperar datos sobre las vidas y obras de María Teresa Lara y María del Refugio Ponce –hermanas de los reconocidos “genios” musicales Agustín Lara y Manuel M. Ponce– , dos creadoras prácticamente ignoradas por el canon musical eurocéntrico y por discusiones académicas sobre compositoras mexicanas. Aplicar teorías acerca de la noción de genio como cómplice ideológico de estructuras patriarcales en el campo musical para investigar de qué forma el culto a sus hermanos podría haber provocado la casi desaparición de estas creadoras.Diseño metodológico: el artículo se basa en una investigación interdisciplinaria que reúne musicología, estudios de género y creatividad. Se realizó también un trabajo de campo en Tlatlauquitepec (Puebla) para rescatar datos sobre María Teresa Lara. En el caso de María del Refugio Ponce, se llevó a cabo un estudio de documentos relevantes y partituras en el Archivo General del Instituto Cultural de Aguascalientes.Resultados: se obtuvieron datos biográficos importantes sobre ambas mujeres, así como indicios de que la ideología del genio y el culto a sus hermanos ha sido parcialmente beneficioso, pero sobre todo una limitante en el desarrollo artístico de las creadoras.Limitaciones de la investigación: la historia de María Teresa Lara todavía se encuentra envuelta en contradicciones y aún hace falta un trabajo muy detallado para determinar el catálogo completo de la obra de María del Refugio Ponce.Hallazgos: el artículo revela la prolífica labor musical de María del Refugio Ponce y la probabilidad de una compleja colaboración artística entre los hermanos Lara que anteriormente ha sido soslayada.
A New Two Parametric Weighted Generalized Entropy for Lifetime Distributions
Authors: Bhad Bilal Ahmad , Baig Mirza Abdul Khaliq
Published: August 2020

The concept of weighted generalized entropy and its dynamic residual (version) is developed. The general expressions of these two uncertainty measures corresponding to some well-known lifetime distributions are derived. It is shown that the proposed dynamic entropy determines the survival function uniquely. Some significant properties and inequalities of this dynamic entropy are also discussed.

Considerando o crescente envolvimento das mulheres nos negócios e consequente representação feminina nas empresas, o estudo proporciona uma análise cross-national da participação feminina nas organizações, investigando a diversidade de gênero nas empresas tanto pela ótica da governança corporativa quanto pela da gestão. Com metodologia quantitativa, descritiva e documental, foram realizados testes de estatística descritiva, análise de variância, correlação de Pearson e regressão linear múltipla em uma amostra composta por 611 empresas do BRICS. Para a diversidade de gênero, variável dependente, foi considerada a participação feminina na governança corporativa, representada pelo conselho de administração, e a gestão das empresas, representada pela alta administração. As variáveis independentes consistiram nos fatores relacionados ao conselho de administração, tamanho da empresa, rentabilidade e cultura nacional, nas suas dimensões individualismo e masculinidade. Verificou-se baixa representatividade feminina nas empresas, sinalizando que as mulheres têm menor participação do que os homens na estrutura de poder das empresas e constatou-se diferenças significativas na participação feminina das empresas entre os países. Ainda, os resultados apontam a rentabilidade e a cultura nacional, representada pelo individualismo e a masculinidade, como fatores determinantes da diversidade de gênero das empresas da amostra. Assim, o trabalho põe em evidência a diversidade de gênero e contribui para a discussão acerca dos fatores determinantes da participação feminina no conselho de administração e na alta administração das empresas, fornecendo evidências empíricas da análise para países de economias emergentes.
