Abstract

Purpose

This paper develops the approach suggested by Howe et al. to examine the impact of cross‐listings on stock price volatility in Europe.

Design/methodology/approach

A modified generalized autoregressive conditional hetero‐skedasticity (GARCH) modeling approach as suggested by Li and Engle is used taking into account different regulatory structures across the range of markets using LaPorta et al.'s stock market regulatory classification.

Findings

It is found that information spillover effects are important for the Dutch market for cross‐listed equities and that a different regulatory environment may have a noteworthy impact on symmetric information spillovers.

Research limitations/implications

The focus is 11 cross‐listing equities and on an event window of 12 years. This implies that the results may be biased on the data sample and the length of the period that used.

Practical implications

The findings are important for the shareholders of cross‐listed companies as the various impacts of regulatory differences between markets (as a result of low and high shareholder protection rules) from foreign markets to the Dutch home market are identified.

Originality/value

A primary focus of this paper is to provide a different methodology than the one adopted by Howe et al. using a modified GARCH modeling approach as suggested by Li and Engle, to examine the impact of the cross‐listings of Dutch firms on symmetric volatility spillovers. The analysis also takes into account the influence of different regulatory structures across the range of markets where Dutch firms are cross‐listed. In particular, we use LaPorta et al.'s stock market regulatory classification is used to analyze the magnitude and persistence of symmetric volatility spillovers from the foreign listing to the home equity of cross‐listed companies in the Dutch stock exchange.

Abstract

Purpose

During the pandemic, people have changed their diet and lifestyle, which are highly important to maintain health and well-being. This study aims to investigate the relationship between demographic, socioeconomic, dietary and lifestyle characteristics and adolescents' adherence to the Mediterranean diet (AMD).

Design/methodology/approach

In all, 2088 youth from Attica, Greece, 12–18 years old, were recruited in this school-based, cross-sectional study conducted in May–December 2021. The tools Mediterranean Diet Quality Index for children and adolescents, the Family Affluence Scale III and the Godin-Shephard Leisure Time Physical Activity Questionnaire were used to estimate AMD, family affluence and the levels of physical activity (PA), respectively. Mann–Whitney U, Kruskal–Wallis, Chi-square tests, analysis of variance and multiple linear regression approaches were applied.

Findings

Empirical results showed that boys (p = 0.000), higher socioeconomic status (p = 0.034) and higher maternal education (p = 0.026) emerged as significant determinants for higher AMD. In addition, healthier dietary patterns (p = 0.000), PA (p = 0.000), more social lifestyle (p = 0.000) and night sleep duration (p = 0.000) were also positively correlated to diet quality. On the contrary, age (p = 0.000), screen time (p = 0.003) and the negative consequences of COVID-19 affected adversely AMD among adolescents.

Originality/value

To the best of the authors’ knowledge, this study was the first that highlighted the important role of several demographic, socioeconomic, dietary and lifestyle characteristics, together with the COVID-19 consequences to the AMD among secondary school children in Greece.

Abstract

Purpose

The purpose of the paper is to present a framework for moving cross-border ePrescription (eP) and Patient Summary (PS) services forward, bearing in mind the needs and requirements of the European e-health space for cross-border eP and PS services, the limitations of the already developed solutions, as well as outcomes available from other domains.

Design/methodology/approach

The outcomes of previous and current large-scale pilot projects, aiming toward the delivery of electronic cross-border services, are examined. Integration of generic building blocks (BBs) is considered for the further development of cross-border eP and PS, in line with the European Directive on patients’ rights in cross-border health care.

Findings

The e-health domain is expected to greatly benefit from mitigating non-domain concerns such as those for electronic identification, end point detection, non-repudiation and the use of electronic signatures and trust establishments for basic cross-border public services in Europe.

Research limitations/implications

Research limitations are related to the fact that electronic identification, electronic signature and semantic issues have not been fully addressed yet at a European level to support cross-border services.

Practical implications

Practical implications are related to the cooperation, European level compatibility and sustainability of the underlying national infrastructures required to support reliable and secure exchange of medical data, as well as the readiness to address continuously evolving interoperability, legal and security requirements in a cross-border setting.

Originality/value

The need for consolidating the existing outcomes of non-health specific BBs is examined for two high-priority e-health services. Ongoing progress is presented, together with related issues that need to be resolved for improving technical certainty and making it easier to use health-care services abroad in cases of emergency.
