Strategic leadership in cyber security, case Finland

2020

Cyber security has become one of the biggest priorities for businesses and governments. Streamlining and strengthening strategic leadership are key aspects in making sure the cyber security vision is achieved. The strategic leadership of cyber security implies identifying and setting goals based on the protection of the digital operating environment. Furthermore, it implies coordinating actions and preparedness as well as managing extensive disruptions. The aim of this article is to define what is strategic leadership of cyber security and how it is implemented as part of the comprehensive security model in Finland. In terms of effective strategic leadership of cyber security, it is vital t…

Conflicts related to Human Resource Management in Finnish Project-Based Companies

2020

In contemporary working life of Nordic countries, employee involvement and well-being are emphasized and organizational functions and demands are continuously changing. Thus, the study of human resource management (HRM) practices and their consequences for employees is relevant. This study examines conflicts related to HRM in Finnish project-based companies and provides new information on the implications of conflicts in HRM practices for theorists and practitioners. The research was conducted qualitatively using content and thematic analysis. The findings suggest that conflicts framed within HRM practices are generally the result of the practices and expectations of the organization and ma…

Muistamisesta ja unohtamisesta verkossa

2020

Internet on ratkaisevalla tavalla muuttanut tapoja, joilla muistamme, unohdamme ja kuolemme. Italialainen filosofi Davide Sisto kirjoittaa suomeksi käännetyssä esseeteoksessaan erityisesti sosiaalisen median roolista tavoissamme muistaa mennyttä. Teos on harhaileva esitys jossain filosofian ja populaarikulttuurin välillä. nonPeerReviewed

Hyvä ja huono johtajuus suomalaisessa pankkiorganisaatiossa

2017

Tämän tutkimuksen fokus on hyvässä ja huonossa johtajuudessa suomalaisessa pankkiorganisaatiossa. Tutkimuksen tarkoituksena on etsiä hyvän ja huonon johtajuuteen tekijöitä organisaation kolmella eri tasolla: ylimmässä johdossa, keskijohdossa ja alimmalla tasolla. Lisäksi tutkimuksen tarkoituksena oli selvittää, löytyykö organisaation eri tasoilla eroja tai yhtäläisyyksiä näkemyksistä hyvästä ja huonosta johtajuudesta. Teoreettisena viitekehys koostuu monista eri johtajuuden tunnetuista teorioista. Viitekehys on jaettu kahteen osaan: hyvän ja huonon johtajuuden teorioihin. Hyvän johtajuuden teoriat ovat johtajuuden tutkimuskentän merkittävimpiä teorioita, jotka tuovat eri näkökulmia johtajuu…

Charge transport through spin-polarized tunnel junction between two spin-split superconductors

2019

We investigate transport properties of junctions between two spin-split superconductors linked by a spin-polarized tunneling barrier. The spin-splitting fields in the superconductors (S) are induced by adjacent ferromagnetic insulating (FI) layers with arbitrary magnetization. The aim of this study is twofold: On the one hand, we present a theoretical framework based on the quasiclassical Green's functions to calculate the Josephson and quasiparticle current through the junctions in terms of the different parameters characterizing it. Our theory predicts qualitative new results for the tunneling differential conductance, $dI/dV$, when the spin-splitting fields of the two superconductors are…

Thermodynamics of a Phase-Driven Proximity Josephson Junction

2019

We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction {in the short limit}. Owing to the proximity effect, such a junction constitutes a thermodynamic system where {phase difference}, supercurrent, temperature and entropy are thermodynamical variables connected by equations of state. These allow conceiving quasi-static processes that we characterize in terms of heat and work exchanged. Finally, we combine such processes to construct a Josephson-based Otto and Stirling cycles. We study the related performance in both engine and refrigerator operating mode.

Anomalous current in diffusive ferromagnetic Josephson junctions

2017

We demonstrate that in diffusive superconductor/ferromagnet/superconductor (S/F/S) junctions a finite, anomalous Josephson current can flow even at zero phase difference between the S electrodes. The conditions for the observation of this effect are noncoplanar magnetization distribution and a broken magnetization inversion symmetry of the superconducting current. The latter symmetry is intrinsic for the widely used quasiclassical approximation and prevented previous works based on this approximation from obtaining the Josephson anomalous current. We show that this symmetry can be removed by introducing spin-dependent boundary conditions for the quasiclassical equations at the superconducti…
