Abstract
Purpose
This paper aims to provide an important perspective to the predictive capacity of Organization of the Petroleum Exporting Countries (OPEC) meeting dates and production announcements for energy futures (crude oil West Texas Intermediate (WTI), gasoline reformulated gasoline blendstock for oxygen blending (RBOB), Brent oil, London gas oil, natural gas and heating oil) market returns and volatilities.
Design/methodology/approach
To examine the impact of OPEC news on energy futures market returns and volatilities, the authors use a conditional quantile regression methodology during the period from April 01, 2013 to June 30, 2017.
Findings
From the empirical findings, the authors show a conditional dependence between energy futures returns and OPEC-based predictors; hence, the authors can find clear the significance of relationship in the process of financialization of the OPEC announcements and energy futures in the case of this paper. From the quantile-causality test, the authors find that the effect of OPEC news is important to energy futures. Specifically, OPEC announcements dates predict the quantiles of the conditional distribution of energy futures market returns.
Originality/value
The authors confirm the presence of unidirectional nexus between OPEC news and energy commodities futures in the long term.

Abstract
Purpose
The field of Professional Development Schools (PDS) continues to evolve with promising implications. As part of advancing practice, the National Association for Professional Development Schools has updated its nine essential guiding principles, which now includes an explicit expectation for all PDS partners to advance equity, anti-racism and social justice. This article is a call for critical professional development work which infuses Disability Critical Race Theory (DisCrit) practices into achieving the Nine Essentials.
Design/methodology/approach
In this call-to-action article, the authors argue that it is imperative for the whole of PDS work to establish a priority for inclusive practice that recognizes and responds to all aspects of diversity in education from the outset, including disability. The authors suggest that PDS work must be guided by an intersectional approach that is operationalized to achieve equity in education by dismantling both racism and ableism in education. The authors use an action-based example from our PDS work to exemplify these elements in practice.
Findings
In this article, the authors put forth two arguments that they urge their PDS colleagues to consider. First, the authors call for practices within PDS to give attention to improving student learning in ways that specifically address disability and intersectional considerations related to disability. Second, the authors urge that PDS work must be conceptually and practically inclusive in order to achieve the social justice impact put forth in the comprehensive mission of the Nine Essentials.
Originality/value
There is a growing body of literature around PDS that addresses theory to practice research and best practices in PDS settings. While some recent publications address inclusive PDS practices, the authors were not able to identify any works related to DisCrit in the PDS literature to date.

This paper aims to investigate how oil price uncertainty affects real gross domestic product (GDP) and industrial production in eight Central and Eastern European countries (CEEC).
Abstract
Purpose
This paper aims to investigate how oil price uncertainty affects real gross domestic product (GDP) and industrial production in eight Central and Eastern European countries (CEEC).
Design/methodology/approach
In the research process, the authors use the Bayesian method of inference for the two applied methodologies – Markov switching generalized autoregressive conditional heteroscedasticity (GARCH) model and quantile regression.
Findings
The results clearly indicate that oil price uncertainty has a low effect on output in moderate market conditions in the selected countries. On the other hand, in the phases of contraction and expansion, which are portrayed by the tail quantiles, the authors find negative and positive Bayesian quantile parameters, which are relatively high in magnitude. This implies that in periods of deep economic crises, an increase in the oil price uncertainty reduces output, amplifying in this way recession pressures in the economy. Contrary, when the economy is in expansion, oil price uncertainty has no influence on the output. The probable reason lies in the fact that the negative effect of oil volatility is not strong enough in the expansion phase to overpower all other positive developments which characterize a growing economy. Also, evidence suggests that increased oil uncertainty has a more negative effect on industrial production than on real GDP, whereas industrial share in GDP plays an important role in how strong some CEECs are impacted by oil uncertainty.
Originality/value
This paper is the first one that investigates the spillover effect from oil uncertainty to output in CEEC.
