Stock Volatility Predictability in Bull and Bear Markets
2020
Recent literature on stock return predictability suggests that it varies substantially across economic states being strongest during bad economic times. In line with this evidence, we document that stock volatility predictability is also state dependent. In particular, using a large data set of high-frequency data on individual stocks and a few popular time-series volatility models, in this paper we comprehensively examine how volatility forecastability varies across bull and bear states of the stock market. We find that the volatility forecast horizon is substantially longer when the market is in a bear state than when it is in a bull state. In addition, the volatility forecast accuracy is…
Unveiling the Role of Multiple blockholders: Evidence from Closely Held Firms.
2019
Research Question/Issue. This paper disentangles how the modes of ownership distribution among multiple blockholders and their heterogeneity shape principal–principal conflicts and, in turn, affect firm performance. The paper offers empirical evidence from a panel of Italian closely held firms over the period 2009–2014. Research Findings/Insights. We explore the principal–principal conflicts among blockholders across two distinct control structures. When a single blockholder controls the firm, principal–principal conflicts are shaped by the trade‐off between the alignment effect and the monitoring effect. In this scenario, we find that the relationship between the two largest blockholders' …
System Dynamics in the Predictive Analytics of Container Freight Rates
2021
This study proposes a two-tier cross-validation and backtesting procedure, including expanding and rolling-window test metrics in predictive analytics of container freight rates by utilizing the system dynamics approach. The study utilized system dynamics to represent the nonlinear complex structure of container freight rates for predictive analytics and performed univariate and multivariate time-series analysis as benchmarks of the conventional approach. In particular, the China containerized freight index (CCFI) has been investigated through various parametric methodologies (both conventional time-series and system dynamics approaches). This study follows a strict validation process cons…
Using a hazard-independent approach to understand road-network robustness to multiple disruption scenarios
2021
Abstract A range of predictable and unpredictable events can cause road perturbations, disrupting traffic flows and more generally the functioning of society. To manage this threat, stakeholders need to understand the potential impact of a multitude of predictable and unpredictable events. The present paper adopts a hazard-independent approach to assess the robustness (ability to maintain functionality despite disturbances) of the Sioux Falls network to all possible disruptions. This approach allows understanding the impact of a wide range of disruptive events, including random, localised, and targeted link failures. The paper also investigates the predictability of the link combinations wh…
Investigating Mobility Gaps in University Campuses
2018
The objective of the present research is to carry out a gap analysis between current mobility situations and the needs, future plans and priorities regarding a number of thematic areas on the issue of mobility in university campuses. For this purpose, an interview was conducted involving 36 experts from seven Southern European Universities. More specifically, experts from each university were asked to analyse and rate both the current and the desired situation in the campus under their responsibility with focus on the following thematic areas: parking management, soft modes infrastructure, public transport, car related issues, road infrastructure, environment and energy, mobility management…
Screening of Foreign Direct Investment and the States’ Security Interests in Light of the OECD, UNCTAD and Other International Guidelines
2021
AbstractThis chapter analyses the concept of the “national security interest”, which is widely recognised as allowing a state to determine which areas of its economy are restricted or prohibited to foreign investors. This chapter seeks to identify what constitutes a threat for a state and how that threat is managed both domestically and internationally. Despite the recognition of a state’s right to take measures it considers essential to its security, there are limits. The rules established by the Organisation for Economic Co-operation and Development (OECD) and the United Nations Conference on Trade and Development (UNCTAD) and other international instruments are non-binding but can serve …
CAN I TELL JUST BY MYSELF? DISCUSSING A PARENTAL MENTAL DISORDER WITH A CHILD IN A RESEARCH INTERVIEW
2016
In this single-case study, we focus on how to have a dialogue in a research interview with a child whose parent has been diagnosed with a mental disorder. The interactional context and the interviewer’s role in co-constructing the child’s accounts have been largely neglected in the qualitative psychological research on this subject. Stigma related to mental disorders is increasingly being recognized as a central issue for the entire mental health field. It is considered to have far-reaching effects on the social interaction of the stigmatized person and also to contaminate the interactions of those around that person. We examine how the stigma of a parental mental disorder arises and is neg…
Alexandre Brierre de Boismont and the limits of the psychopathological gaze
2018
One of the most remarkable implications of psychological medicine in the transition from the 18th to the 19th century was the advent of a new way of looking at the human being and new tools for analysing not only behaviour and individual experience, but also historical events, collective behavioural patterns or complex cultural achievements. Unsurprisingly, the deployment of this gaze could not advance without there being a series of disputes and controversies about its reach and the limits to its indiscriminate application. Focusing on the figure of French alienist Alexandre Brierre de Boismont and on the controversial cases of hallucinations and suicide, this article addresses the confli…

Lügenerwerb und Geschichten vom Lügen
2011
The acquisition of lying is a complex developmental process, where linguistic, cognitive, emotional and moral aspects are intertwined. It is shown that this developmental process is reflected in children’s literature. Since lying is indeed a very important topic in children’s literature, as is shown with regard to children’s books ranging from picture books to books for children in school age to books for young adults, we argue that this topic cannot be well understood when these developmental aspects are not taken into consideration.
