Abstract:
BackgroundIn 2004, researchers reported that the number of nephrology clinical trials was low and that the reporting quality of such trials was suboptimal. Furthermore, the number or quality of preclinical kidney-related studies has not been systematically evaluated.MethodsWe performed a systematic review of randomized clinical trials published in 1966–2017 (listed in the Cochrane Library) and preclinical studies published in 1945–2017 (listed in PubMed). For reporting quality analysis, we evaluated the final main paper of 118 clinical trial reports and 135 preclinical studies published in leading journals in 1996, 2006, and 2016 on the basis of criteria from the widely used CONSORT and ARRIVE guidelines.ResultsThe annual number of reports of clinical kidney-related trials more than doubled between 2004 and 2014 along with reports in other medical disciplines. Hypertension remains the dominant focus of study, but ongoing trials also center on CKD, ESRD, and AKI. The reporting quality analysis revealed improvements, but deficits in reporting of clinical trial design, mode of randomization, and intention-to-treat analysis remain. Annual numbers of kidney-related preclinical studies remained low between 1945 and 2017 compared with other disciplines. Reporting quality analysis of preclinical studies revealed substantial reporting deficits across all leading journals, with little improvement over the last 20 years, especially for group size calculations, defining primary versus secondary outcomes, and blinded analysis.ConclusionsNephrology studies keep increasing in number but still lag behind other medical disciplines, and the quality of data reporting in kidney research can be further improved.

Abstract:
Abstract Exposimetry of electromagnetic fields refers to a measurement technology aiming to quantify the immission or absorption of fields and/or energy in specific ranges of the electromagnetic spectrum. Portable, small and accurate measurement instruments were developed to provide tools for epidemiological research and environmental monitoring. The target measurement quantity was the average amount of RMS field strength that an average individual will experience in everyday environments. This quantity can be used to classify different groups of the population or to track changes in exposure conditions within defined regions or along specified tracks. Methods and tools for the assessment of the personal exposure to low-frequency magnetic fields (LF-MF), radio frequency electromagnetic fields (RF-EMF) and pulsed RF emissions from radar installations have been developed, characterized, and tested. The result is a measurement platform enabling a large variety of measurement procedures and study protocols.

Abstract:
Voluntary peer review is generally provided by researchers as a duty or service to their disciplines. They commit their expertise, knowledge and time freely without expecting rewards or compensation. Peer review can be perceived as a reciprocal mission that aims to safeguard the quality of publications by helping authors improve their manuscripts. While voluntary peer review adds value to research, rewarding the quantity or the volume of peer review is likely to lure academics into providing poor quality peer review. Consequently, the quantity of peer review may increase, but at the expense of quality, which may lead to unintended consequences and might negatively affect the quality of biomedical publications. This paper aims to present evidence that while voluntary peer review may aid researchers, pressurized peer review may create a perverse incentive that negatively affects the integrity of the biomedical research record. We closely examine one of the proposed models for rewarding peer review based on the quantity of peer review reports. This article also argues that peer review should remain a voluntary mission, and should not be prompted by the need to attain tenure or promotion.

The debate on quality versus quantity is still persistent for methodological considerations. These two approaches are highly contrasting in their epistemology and contrary to each other. A single composite indicator that reasonably senses both quality and quantity would be significant toward performance. This paper evaluates the potency of the combined metric for quality assessment of publications (QP) in India’s National Institutional Research Framework (NIRF) exercise in 2020. It also suggests a potential improvement in quality measurement to obtain the rankings more rationally with finer tunings.

Abstract:
Apparent discharge quantity is usually recognized as judgement standard for severity of partial discharge in the field of electrical equipment insulation diagnosis. In recent years, the ultra-high-frequency (UHF) method has been widely used due to its unique advantages on on-line monitoring and positioning, but the relationship between UHF partial discharge signals and discharge quantity is still a difficult problem of UHF method. In order to research relationship between UHF partial discharge signals and discharge quantity in GIS, a large number of experiments, based on four kinds of typical insulation defects in the GIS, are carried out. Degree of correlation, between parameters including UHF energy, quadratic integral, peak voltage, peak-to-peak value, wave area and discharge quantity, the square of discharge quantity, is studied based on coefficient of determination. The experimental results show there is linear relation between UHF signal energy and the square of discharge quantity with high related degree.

This paper presents evaluation models and methods for assessing groundwater quantity and pollution vulnerability. The models and methods were used to evaluate the groundwater vulnerability in the plain area of Baotou, Inner Mongolia, China. The groundwater quantity vulnerability was assessed by computing the groundwater recharge rate, and the GPV was evaluated by simulating the migration time for pollutants traveling from ground surface to the aquifer. The research results could provide scientific support for the management of regional groundwater resources, prevention and control of groundwater pollution.

Abstract:
In order to explore carbon market regulation mechanism more effectively, based on carbon accumulation model with jump diffusion, this paper studies the carbon price from two perspectives of quantity instrument and price instrument and quantitatively simulates carbon price regulation mechanisms in the light of actual operation of EU carbon market. The results show that quantity instrument and price instrument both have certain effects on carbon market; according to the comparison of the elasticity change of the expected carbon price, comparative advantages of both instruments rely on the price of carbon finance market. Where the carbon price is excessively high, price instrument is superior to quantity instrument; where carbon price is excessively low, quantity instrument is better than price instrument. Therefore, in the case of carbon market regulation based on expected carbon price, if the carbon price is too high, price instrument should prevail; if the carbon price is excessively low, quantity instrument should prevail.
