Study of phonon and electron subsystems of C60I4-x and C60Br24 crystals has shown a different character of chemical bonding in these materials: C60I4-x is a compound with weak van der Waals interaction between C-60 and I-2 molecules whereas C60Br24 is a covalent crystal with a charge transfer between nearest C and Br atoms.

The large MIMIC waveform dataset, sourced from intensive care units, has been used extensively for the development of Photoplethysmography (PPG) based blood pressure (BP) estimation algorithms. Yet, because the data comes from patients in severe conditions-often under the effect of drugs-it is regularly noted that the relationship between BP and PPG signal characteristics may be anomalous, a claim

The electronic structure of C60n- molecules and ions and C60Kn (n=0-4,6) crystals is investigated in the zero diatomic overlap approximation. The calculated characteristics of the carbon-carbon chemical bond in fullerenes and fullerites are compared with the bond characteristics in simpler covalent carbon-containing compounds, viz.: selected hydrocarbons, graphite, and diamond. It is shown that t

Using cyclic boundary conditions and LCAO basis allows one to reproduce both band and local properties of the electronic structure of a crystal. Electronic structure of a row of composite copper and lead crystalline oxides are studied within the CNDO approximation, and the local properties (atomic charges, bond orders, valencies) are analyzed. A comparison of the local properties of some high-Tc s

Healthcare organizations are challenged by complexity in structure and knowledge, and heterogeneity in deliveries and patient demands. Reductionist managerial approaches fall short in resolving the quality issues of healthcare, but Scientific Management and New Public Management (NPM) nevertheless has a strong hold on leadership thinking in hospitals. Increasing demand for adaptive and collaborati

The article presents an empirical study of informal leadership in an international high-tech company. The empirical work consisted of qualitative observation and shadowing of managers in the company, and a total of 14 interviews. The transcribed fieldnotes and audio recordings of observations and interviews were analyzed thematically, resulting in three central themes: informality, information basThe article presents an empirical study of informal leadership in an international high-tech company.

Followership research has increased recently, but little attention has been paid to the complexities and challenges of creating a followership identity. Researchers typically portray followership as a safe alternative to leadership identity, but we challenge this assumption by using naturally occurring workplace interactions to identify active contributions as well as risks associated with a follo

A chapter on leadership in interaction might appear to address an odd topic, because many observers would contend that interaction is integral to all leadership. However, empirical studies of the processes of interaction are relatively rare in the leadership field. In recent years, though, this perspective has been emerging; therefore, this chapter will present and discuss this emergent work while

The concept of authentic leadership is increasingly the focus of much leadership scholarship, and many have called for a review of the basic assumptions that underpin it. Taking an interactional approach to authentic leadership (AL) and using naturally occurring workplace interaction as data, we seek to question two basic assumptions of AL scholarship, namely (1) that authentic leadership emanatesThe concept of authentic leadership is increasingly the focus of much leadership scholarship, and many have called for a review of the basic assumptions that underpin it.

This article studies the organisational view inherent in a public management and leadership development programme. Organisational views are important to study as they guide and frame the actions of the members of the organisation. In the management and leadership development programme under investigation the organisational view was a linguistic-discursive representation that was empirically inept,

This article explores the relationship between management and leadership development and leadership practice. Critical studies of management and leadership development programmes have mainly focused on such programmes as spaces for identity work and/or identity regulation. This article extends the literature by investigating the notion of organisation, the organisational view, in a large managemen

Peer interaction is a standard aspect of most leadership development programmes and is seen to be conducive to learning. Realising deeper and critical reflexivity in peer interaction is, however, challenging. This study employs conversation analysis to empirically explore peer interactions in a leadership development programme for first-line managers in the public sector in Denmark. The analysis s

The Second Edition of The SAGE Handbook of Leadership provides not only an in-depth overview the current field of leadership studies, but also a map into the future debates, innovations and priorities of where the field will move to. Featuring all new chapters from a global community of leading and emerging scholars, each chapter offers a comprehensive, critical overview of an aspect of leadership
