Dependence between renewable energy related critical metal futures and producer equity markets across varying market conditions
2022
We study the dependence of renewable energy production-related critical metal futures and producer equity returns, compared to the non-renewable energy (oil and natural gas) and some other globally relevant commodity markets. We find different asymmetric and symmetric dependencies in these commodity markets. The dependence is asymmetric in the most important critical metal markets, i.e., of silver, copper, and platinum. Still, surprisingly, for example, in the oil market, the relationship is symmetric, and no relationship is found in the natural gas market. Furthermore, the oil and agricultural markets have homogenous dependence structures in most market conditions, so the information trans…
Cluster-Randomized Studies.
2018
Background Cluster-randomized trials (CRT) are needed to compare interventions that are allocated to entire groups of subjects, rather than to individuals. Publications about CRT have become steadily more common over the past decade. Readers of such publications should be able to categorize and interpret the findings of CRT correctly while considering the methodological requirements applicable to this type of study. Methods This review is based on a selection of pertinent literature and on the authors' expertise. CRT-specific methodological aspects of the planning, performance, and interpretation of studies are discussed. Results Readers of publications on CRT should check whether due consi…
Gd-DTPA in blood-ocular barrier damage: a new diagnostic tool for future application in MRI?
1995
The blood-brain barrier is not the only neuroepithelial blood filter in the body: the eye too is supported by a highly specialised microvascular filter, the so-called blood-ocular barrier (BOB). The BOB is actually divided into a blood-aqueous (BAB) and a blood-retinal (BRB) barrier, filtering the aqueous fluid and biological supplies, respectively, to the retina. The authors’ purpose was to study the possibility of imaging BAB or BRB damage by contrast-enhanced MRI: they examined 21 patients with a 0.5 T system and surface coil. Despite the normal findings in the damaged eyes immediately after a Gd-DTPA bolus, delayed contrast-enhanced MRI was able to show focal or diffuse barrier damage.
The response of Brent crude oil to the European central bank monetary policy
2022
Este artículo examina el impacto de las decisiones de política monetaria del Banco Central Europeo (BCE) sobre los precios del petróleo y la liquidez mediante un estudio de eventos con datos intradía. Analizamos el período de enero de 1999 a diciembre de 2020, que incluye la crisis financiera que comenzó en agosto de 2007. Nuestros resultados muestran una respuesta significativa de los rendimientos del petróleo solo durante la crisis financiera. Específicamente, encontramos que los rendimientos de los futuros de petróleo crudo Brent respondieron negativamente a variaciones inesperadas en la prima de riesgo italiana como medida de acciones de política monetaria no convencionales, y positivam…
Anatomy of Risk Premium in UK Natural Gas Futures
2015
In many futures markets, trading is concentrated in the front contract and positions are rolled-over until the strategy horizon is attained. In this paper, a pair-wise comparison between the conventional risk premium and the accrued risk premium in rolled-over positions in the front contract is carried out for UK natural gas futures. Several novel results are obtained. Firstly, and most importantly, the accrued risk premium in rollover strategies is significatively larger than conventional risk premiums and increases with the time to delivery. Specifically, for strategy horizons between three and six months, this difference increases from 1% to 10%. Secondly, it is the first time that risk …
Rolling Over EUAs and CERs
2012
Whatever derivative contract has a finite life limited by their maturity. The construction of long series, however, is of interest for academic, hedging and investments purposes. In this study, we analyze the relevance of the choice of the rollover date on European Union Allowances (EUAs) and Certified Emissions Reduction (CERs) futures contracts. We have used five different methodologies to construct long series and the results show that, regardless of the criterion applied, there are not significant differences between the resultant return distribution series. Therefore, the least complex method, which is to roll on the last trading day, can be used in order to reach the same conclusions.…
SQL Education
2020
Structured Query Language (SQL) skills are crucial in software engineering and computer science. However, teaching SQL effectively requires both pedagogical skill and considerable knowledge of the language. Educators and scholars have proposed numerous considerations for the betterment of SQL education, yet these considerations may be too numerous and scattered among different fora for educators to find and internalize, as no systematic mappings or literature reviews regarding SQL education have been conducted. The two main goals of this mapping study are to provide an overview of educational SQL research topics, research types, and publication fora, and to collect and propagate SQL teachi…
Frame analysis of psychotherapists’ perspectives on the development of psychological disorders
2021
AbstractThe development of psychological disorders has been explained by several psychological theories and remains under debate. Psychotherapists, however, have insights into the emergence and development of psychological disorders that stem from both theory and practice. The constantly evolving field of psychotherapy prompts reconsideration, specifically when psychotherapists’ views on the development of disorders impacts their treatment approach. In addition, theoretical orientation and years of clinical experience, while known to influence psychotherapists’ viewpoints also merit further study. Applying Erving Goffman’s frame analysis, semi structured interviews with psychotherapists wer…

Metilazione del DNA in artrite reumatoide
2005
Lo stato di metilazione del DNA genomico e del gene PTHrP è stato valutato con tecniche molecolari e citogenetiche in artrite reumatoide (AR), patologia autoimmune caratterizzata anche da alta incidenza di linfomi e da ipercalcemia per overespressione del gene PTHrP. La metilazione del DNA, infatti, ha un ruolo critico nello sviluppo delle malattie neoplastiche; il gene PTHrP avendo tre promotori uno dei quali contiene un’isola CpG è un buon candidato per la deregolazione da alterato pattern di metilazione locale. Le indagini sulla metilazione genomica, condotte su DNA estratto da sangue periferico di pazienti e di donatori e amplificato in reazioni di Methylation-Sensitive Arbitrarily Prim…
