Do drivers of renewable energy consumption matter for BRICS economies? Nexus among technological innovation, environmental degradation, economic growth, and income inequality

In light of increasing concerns about climate change and energy security, renewable energy has been seen as the most promising solution to fulfl future energy needs. This study examines the drivers of renewable energy consumption (REC) and the nexus between GDP growth, technological innovation, gross fxed capital formation, CO2 emissions, income inequality, and renewable energy consumption (REC) using annual data from BRICS countries. To this end, the study uses the augmented mean group (AMG) estimator, a second-generation estimator that takes slope homogeneity and cross-sectional dependence into consideration. For robustness, the pooled mean group (PMG) estimator has also been utilized. The fndings of both estimators indicate that carbon emissions, technological innovation, and gross fxed capital formation exert adverse and signifcant impacts on REC. The fndings also show that the use of renewable energy will rise as income inequality declines. We also employ the Dumitrescu and Hurlin (DH) granger causality test. The results of the analysis demonstrate a one-way causal association between income inequality and REC. This fnding confrms that a reduction in income inequality will have a major impact on the adoption of renewable energy sources

Knowledge towards post-mortem examination and reasons for not specialising in morbid anatomy: study among medical undergraduate students

Background: The use of autopsy in medical education has been declining just as autopsy rate has been falling worldwide. This is further worsened by the prevention of medical students from attending autopsy sections in some areas. Aim of the study was to ascertain the knowledge of medical students towards autopsy and post-mortem examination. An additional objective was to assess reasons for not specialising in morbid anatomy.  Methods: The present cross sectional study was carried out among students of a medical college in Uttar Pradesh in the month of February 2016 using pretested self-administered questionnaire. The study population consisted of undergraduate medical students who were currently studying the forensic medicine and toxicology. A detailed proforma containing 20 questions was framed for the purpose of capturing socio-demographic information of the study participants, questions concerning knowledge about the post-mortem and reasons for not specializing in morbid anatomy.Results: 82.2% were aware that post-mortems are conducted to know the cause and manner of death. Three students (3.3%) opined that the post-mortem is to harass the relatives of the deceased. Almost all the students were having a fair knowledge about the gross procedure involved in the post-mortem examination. Majority of male students would not wish to specialize in morbid anatomy because it deals with death, while most of female students said either they had made up their mind to specialize in some other fields or they do not want to touch and dissect dead bodies.Conclusions: Students possess a reasonable knowledge about post-mortem but knowledge alone may not be enough for increasing the post-mortem/autopsy rate, unless they acquire the skills required for the procedure as currently they are not provided with any training during their medical curriculum.

Medical student’s perceptions of different teaching aids from a tertiary care teaching institution

Background: In recent years there has been increasing interest and growing concern regarding the role of learning environment in undergraduate medical education. Student’s feedback can play vital role in this regard. Aim of the study was conducted to access student’s perception of different teaching aids in a medical college, with an aim to improve their use in didactic lectures.Methods: In this cross-sectional study, all the medical undergraduate students currently studying in the second year were included in this study. A self-administered questionnaire served as study tool. The study population consisted of undergraduate medical students (MBBS) who were currently posted in the Department of Forensic Medicine for theory and practical classes. Questionnaire was handed out to 86 students. The inventory consisted of 25 items and each item scored on a five-point likert scale.Results: Out of 86, 80 returned the completely filled questionnaires. 62 (77.5%) out of 80 had their schooling in English medium and the visual aid predominantly used in the schools. Study subjects preferred a combination of audio-visual aids during a didactic lecture. Blackboard teaching was preferred in the following areas: Facilitated interaction between student and teacher, Aroused interest in learning, Helped to hold attention in class, More helpful to grasp the content, Better able to cope with teaching speed of teacher, More useful in small group, Increased ability to think and understand.Conclusions: Student’s preferences and feedback need to be taken into consideration when using multimedia modalities to present lectures to students. Feasible student suggestions must be implemented for further improving the use of audio-visual aids during didactic lectures to make teaching learning environment better.

Do energy resources matter for growth level? The dynamic effects of different strategies of renewable energy, carbon emissions on sustainable economic growth

Correction to: Do Energy Resources matter for Growth Level? The dynamic effects of different strategies of renewable energy, carbon emissions on sustainable economic growth (Clean Technologies and Environmental Policy, (2022), 10.1007/s10098-022-02432-9) - 2-s2.0-85144909701This study examines the association between renewable energy strategies and carbon emissions on sustainable economic growth under affordable and clean energy sources to achieve sustainable development goal seven. This research provides new insight by exploring the nexus between environmental pollution and the creation of numerous bases of renewable energies, such as hydropower, wind power, biomass, geothermal, and solar photovoltaic, and economic growth epitomizing capital, trade openness, and government spending. Moreover, this investigation uses second-generation devices for econometric investigation and a heterogeneous methodology for panel data for selected Asian countries. The empirical exploration of long-term influences drove by the Common Correlated Effects Mean Group, close by Augmented Mean Group and Mean Group assessors confirm the positive and significant influence of renewable energy like hydropower, solar photovoltaic, wind, biomass, and geothermal on the economic growth of Asian economies. Study findings provide valuable insights for all stakeholders in an integrated and coherent manner

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV
