The Qualitative Researcher in the Quality of Life Field

2015

In the current society, there is a plurality of perspectives about the knowledge of the world and in that stage there is an expansion of the use of qualitative methods as expression of the contemporary interest in the subject-matters, considering the epistemological relevance acquired by the introduction of the subject’s word as a possibility to construct knowledge. The qualitative researcher is expected to feel personally involved in every step of the research process, because every consideration and decision will have to be based on entirely personal grounds. Thus, in this chapter, we shall look into the importance of the qualitative researcher’s leading role in each phase of the research…

Paraconsistent logics, conventionalism and ontology

2004

Paraconsistent logics may be viewed as one of the last elements in a series of rapid developments in science in the 19th and early 20th c., triggered by the appearance of non-Euclidean geometries. The philosophy of conventionalism, which gave a metatheoretical framework to the basic changes involved, may also help in evaluating the truth import of (paraconsistent) logic and in determining its relation to ontology.

On the Multifractal Character of the Lorenz Attractor

1992

A detailed analysis of the Lorenz attractor in connection with generalized dimensions is presented in this work. Different methods have been employed to estimate these dimensions. Two of them are of standard type. A new method, based on the minimal spanning tree of the point distribution, is extensively tested in this work. It turns out that the Lorenz attractor is very appropriate for being analyzed through this technique, which produces a very clean estimate of the extrema scaling indices α min and α max . The different methods give qualitatively the same result: The Lorenz attractor has a multifractal character

The effectiveness of leadership development in the military context from a gender viewpoint

2021

In this case study, leadership development is investigated from the viewpoint of women in a military context. In particular, the effectiveness of a leadership development program in a specific context, namely the Finnish Defence Forces, is explored. The program being studied is unique because it is concerned with developing volunteers, not professional soldiers. A longitudinal, interview-based study of the topic was conducted with women who had participated in the program. The data consists of 45 open-ended interviews with 15 women. Each woman was interviewed three times: at the beginning, in the middle and at the end of the program. Content analysis was used to analyse the data. The result…

A set of indices to assess the real performance of daylight-linked control systems

2017

Abstract The installation of Building Automation Control Systems (BACs) in general is an effective action to achieve relevant energy savings. Commercial BACs, installed in residential or small offices, often include functions of lighting control, acting as Daylight-Linked Control Systems (DLCSs). Nevertheless, because system performance is strictly dependent on different parameters, BAC’s hardware and software configuration and as well as an inaccurate commissioning do not always allow a perfect execution of the desired tasks; therefore, the system could not work as expected. Moreover, it is well known that energy saving potential is specifically related to the variability of the light envi…

Wireless ECG and cardiac monitoring systems: State of the art, available commercial devices and useful electronic components

2021

Abstract Wireless ElectroCardioGram (ECG) systems are employed in manifold application fields: tele-monitoring, sport applications, support to ageing people at home, fetal ECG, wearable devices and ambulatory monitoring. The presence of cables often hinders user’s free movements, alongside clinicians’ routine operations. Therefore, wireless ECG systems are desirable. This paper aims at reviewing the solutions described in the literature, besides commercially available devices and electronic components useful to setup laboratory prototypes. Several systems have been developed, different in terms of the adopted technology; when approaching the development of a wireless ECG system, some import…

Molecular surveillance of norovirus, 2005–16 : an epidemiological analysis of data collected from the NoroNet network

2018

BACKGROUND: The development of a vaccine for norovirus requires a detailed understanding of global genetic diversity of noroviruses. We analysed their epidemiology and diversity using surveillance data from the NoroNet network.METHODS: We included genetic sequences of norovirus specimens obtained from outbreak investigations and sporadic gastroenteritis cases between 2005 and 2016 in Europe, Asia, Oceania, and Africa. We genotyped norovirus sequences and analysed sequences that overlapped at open reading frame (ORF) 1 and ORF2. Additionally, we assessed the sampling date and country of origin of the first reported sequence to assess when and where novel drift variants originated.FINDINGS: W…

Motivational sources of practical nursing students at risk of dropping out from vocational education and training

2019

The aim of this study was to contribute to the understanding of the reasons for low or high academic motivation among practical nursing students at risk of dropping out from vocational education and training. The research data consisted of semi-structured interviews with 14 Finnish students, which were analysed by qualitative content analysis. The analysis identified six motivational sources. Two of these sources – Responsible agency and Completing out of necessity – were related to engagement in studying, whereas two other sources – Exhaustion from learning challenges and Tight-roping between competing responsibilities – were related to disengagement from studying. Emotional drive and Soci…

Pedagogical approaches for e-assessment with authentication and authorship verification in Higher Education

2019

Checking the identity of students and authorship of their online submissions is a major concern in Higher Education due to the increasing amount of plagiarism and cheating using the Internet. The literature on the effects of e-authentication systems for teaching staff is very limited because it is a novel procedure for them. A considerable gap is to understand teaching staff' views regarding the use of e-authentication instruments and how they impact trust in e-assessment. This mixed-method study examines the concerns and practices of 108 teaching staff who used the TeSLA—Adaptive Trust-based e-Assessment System in six countries: the UK, Spain, the Netherlands, Bulgaria, Finland and Turkey.…
