Effects of operational assessment of the 4:4 and 4:4/6:6 watch systems on sleepiness, fatigue, and stress responses during patrolling on a navy missi…
2022
The operation of naval vessels involves watchkeeping 24 h per day, which is globally carried out by a variety of different watch systems. In this study, the rotating 4:4 and fixed 4:4/6:6 two-section watch systems were compared in terms of sleepiness, fatigue, and stress responses. The data collection took place on a Finnish Defence Forces' (FDF) Navy missile patrol boat with 15 crew members serving as study participants. The data collection periods lasted two separate weeks (7 days, 6 nights) with the different watch systems. The subjective sleepiness of the participants was assessed before and after every watch using the Karolinska Sleepiness Scale (KSS). Stress responses were assessed da…
Los beneficios del mar: negocios e inversiones económicas de la oficialidad naval en el siglo XVIII
2019
Throughout the eighteenth century, the Spanish navy was extensively reformed and enhanced as a consequence of the new model of Monarchy that the Bourbons introduced. Among the measures adopted, it is remarkable the erection of the naval officers corps according to the needs and obligations that maritime war had in this century. This group becomes the paradigm of the new professionalization and new training approach, and its members had great relevance due to its great mobility around the empire and the power of the naval institution. This means that a part of the naval officers were placed in privileged positions and at the intersection of diverse political, social and economic networks. Th…
Remarks on the History of the Navy of the Empire of Nicaea in the Light of the Chronicle of Georgios Akropolites
2016
The Empire of Nicaea was a successor of the Byzantium shattered in 1204. In the newly established state marine traditions of Byzantines, remain alive. The best testimony to this, are the evidence contained in the chronicle of Georgios Akropolites, devoted to activities of the rulers of Nicaea, aimed to build their own naval forces. In this paper I'll also try to answer, where was beating the heart of the Nicean shipbuilding industry and how large was the navy of this state. This is important from point of view of the maritime history, because of the fleet of the Empire of Nicaea, filled the gap created after the fall of Constantinople and the Byzantine Empire, which was the local naval powe…

Introduction: Mediterranean Movements and the Reconfiguration of the Military-Humanitarian Border in 2015
2018
This article deals with the transformations occurred in the government of refugees in the Mediterranean since 2013, when the military-humanitarian operation Mare Nostrum was launched by the European Union. The paper analyses how military and humanitarian practices are entangled in governing refugees and develops the notion of military-humanitarianism. The Mediterranean borderzone has undergone radical reconfigurations over the last few years. Particularly, new technologies of control for strengthening the role of the Mediterranean Sea as a pre-frontier of Europe have been put in place. The production and the declaration of a "refugee crisis" in Europe has contributed to producing important …
Warfare dendrochronology: Trees witness the deployment of the German battleship Tirpitz in Norway
2019
Abstract War has an immediate and obvious effect on people and communities, but its impacts on local ecology can be more subtle. This paper shows how one military encounter in the Second World War has left a clear legacy in the northern forests of Norway, trackable more than seventy years later. We used annual growth rings of ∼180 pine and ∼30 birch trees as witnesses of the deployment of the German battleship Tirpitz at the Kafjord. The Tirpitz was the target of several Allied air attacks, but the Kriegsmarine (German navy from 1935 to 1945) used artificial smoke, consisting of chlorosulfonic acid and zinc/hexachloroethane, to hide the ship. These smoke-screen actions throughout 1944 cause…
The Effects of Individual Characteristics of the Naval Personnel on Sleepiness and Stress during Two Different Watchkeeping Schedules
2022
Background: Naval service can have a significant impact on the wellbeing of seafarers, and the operation of warships is highly dependent on the personnel on board. Nevertheless, there is a lack of knowledge concerning the impact of seafarers’ individual characteristics on their wellbeing in a naval environment. Therefore, the aim of this study was to investigate individual characteristics of the naval personnel that may be associated with the amount of sleepiness, fatigue and stress responses experienced during shift work and irregular working hours in a naval environment. Methods: The study took place on a Finnish Defence Forces’ Navy missile patrol boat on which 18 crewmembers served as s…

Rosyjskie siły lądowe i flota bałtycka w 1715 i 1719 roku w świetle raportów brytyjskich
2020
Wielka wojna północna oznaczała zmierzch starych potęg takich, jak Szwecja czy Rzeczypospolita i narodziny nowej - Rosji cara Piotra I. Przeprowadził on w państwie głębokie reformy oraz zmodernizował i unowocześnił siły zbrojne, tworząc bałtycką flotę wojenną. Zmiany te nie uszły uwadze ambasadorów obcych państw, w tym oczywiście Wielkiej Brytanii, którzy raportowali o nich do centrali. Sporządzali także zestawienia sił zbrojnych Rosji, w tym marynarki oraz umieszczali przy takiej okazji trafne spostrzeżenia dotyczące żołdu czy werbunku marynarzy. Kilka z nich będzie przedmiotem analizy, a dane które można z nich odczytać będą mogły świadczyć o rozwoju carskich sił zbrojnych.
