Optimal Dynamic Portfolio Risk Management
2016
Numerous econometric studies report that financial asset volatilities and correlations are time-varying and predictable. Over the past decade, this knowledge has stimulated increasing interest in various dynamic portfolio risk control techniques. The two basic types of risk control techniques are: risk control across assets and risk control over time. At present, the two types of risk control techniques are not implemented simultaneously. There has been surprisingly little theoretical study of optimal dynamic portfolio risk management. In this paper, the author fills this gap in the literature by formulating and solving the multi-period portfolio choice problem. In terms of dynamic portfoli…
From Neo-Functional Peace to a Logic of Spillover in EU External Policy: A Response to Visoka and Doyle
2017
In their recently published JCMS article, Gezim Visoka and John Doyle have proposed the concept of ‘neofunctional peace’ as a means to conceptualize the EU's peacemaking practices in the case of the EU-facilitated Belgrade-Pristina dialogue. This article challenges the ‘neo-functional peace’ on conceptual and empirical grounds. We critically discuss Visoka and Doyle's (2016) reading of neofunctionalism and question parts of their empirical evidence given for the existence of a ‘neo-functional peace’. Going beyond a mere critique of the article by Visoka and Doyle and arguing that the authors may not have fully exploited neofunctionalism's potential for theorizing EU external policy, we stip…
Dwuizbowy parlament i reformy instytucjonalne w Republice Włoskiej
2019
Parliaments are dual institutions by nature, as they connect society with the legal structure of the state power. An analysis of the structural properties of contemporary legislative bodies indicates the particular importance of the factor of internal organization, which makes it possible to distinguish a symmetrical bicameralism. The case of Italy is attractive for researchers of political systems for many reasons. One of them is a fact, that both chambers hold the identical legal and political positions, have the same five years’ terms of office and identical scopes of authority. The proportional voting system guaranteed (with two exceptions) that the legislative branch was a mirror image…
Znaczenie unijnego systemu wjazdu/wyjazdu dla wzmocnienia bezpieczeństwa i skutecznego zarządzania granicami zewnętrznymi
2019
The importance of the EU Entry/Exit System to strengthen the security and effective management of the EU’s external borders The European Union strives for modern and effective border management through the use of the new technologies. This study concerns the adopted on 30 November 2017 EU Entry/Exit System. This system, which is expected to become fully operational by 2020, should contribute to the acceleration of border controls at the external borders of the Schengen area and increase the freedom of movement while enhancing the Union’s internal security. In addition, it is currently replacing the existing system of manual stamping of passports and will register electronic data on entries/…
Back pain in a group of computer workers assessed in a physiotherapy unit
2021
BACKGROUND: Modern society work implies computer-based activities generating back pain because of prolonged sitting positions and non-ergonomic postures. OBJECTIVE: The aim of the study was to analyse the back-pain characteristics in a group of office workers in comparison with potential risk factors. METHODS: The design of the study was retrospective; a group of 109 computer workers with back pain was selected from a private physiotherapy unit between Jan 2018 - Dec 2019. Anthropometric, occupational and behaviour data, symptoms, the diagnosis on the first visit, previous medical diagnosis and specific physical activities were collected from medical records. RESULTS: The studied group (res…
An exploration of digital ride-hailing multisided platforms' market dynamics: empirical evidence from the Uber case study
2020
PurposeThe purpose of this paper is to experiment a dynamic performance management (DPM) approach to explore and assess the business dynamics of digital ride-hailing platforms with a focus on both supply and demand sides, and related interplays.Design/methodology/approachThe research adopts the DPM framework supported by simulation-based experimentations for developing a systemic case interpretation of Uber Inc. and its specific business complexity.FindingsThe emerging scenario analysis reveals that changes in the commission percentage for drivers and cutting prices for customers (car hailers) by competitors have significant impacts on the car-hailing industry.Originality/valueDPM and assoc…
The Role of Work-Nonwork Boundary Management in Work Stress Recovery
2016
The aim of the present study conducted among 1,106 Finnish employees was to identify boundary management profiles based on cross-role interruption behaviors from work to nonwork and from nonwork to work. Adopting a person-oriented approach through latent profile analysis, 5 profiles were identified: Work Guardians (21% of the employees), Nonwork Guardians (14%), Integrators (25%), Separators (18%), and an Intermediate Group (22%). We then examined differences between these profiles with respect to recovery experiences ( psychological detachment from work, relaxation, mastery experiences, and control during off-job time) and recovery outcomes (vigor and exhaustion). Work Guardians had the po…
The Impact of Lbos on Investment Policies and Operations of Acquired French Firms
2002
This paper evaluates the extent that French LBO targets’ investment policy and operations can account for their overperformance discrepancy. Our empirical study has been carried out on 132 French LBOs between 1989 and 1994. The results show that the abnormal plunge in economic return cannot be explained by overinvestments or by inefficient working capital management. Nevertheless, abnormal increases in wages, supplies and/or sales price reductions appear to be prominent.

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' …
