Evaluating Safety Systems for Machine Tools with Computer Numerical Control using Analytic Hierarchy Process
2019
Computer numerical control (CNC) machine tools are complex production systems with fully automatic machine parts. Nowadays, high feed rates and machining speeds are used during the machining process. Human operators are still needed to set-up the machine, load/unload workpieces and parts, load the machining code, and supervise the machining process. The operators work in an environment where automated high-speed motions occur, and consequently, CNC machine tools have to be equipped with safety systems. The approach presented in this paper was to evaluate the main safety systems of CNC machine tools based upon the analytic hierarchy process (AHP). The analyzed systems were divided into six m…
«Axí com...» Le comparazioni nella lirica di Jordi de Sant Jordi
2005
Jordi de Sant Jordi uses more than thirty comparisons in his lyric poetry. These may be classified on the basis of their typology and semantic functions: true comparisons (where two elements are compared by means of a connector, the first being defined as ‘real’ and corresponding to the situation of the lyric persona, the second, figurative, presenting in metaphorical terms the same characteristics as the first element); comparisons between the ‘real’ situation and that of an unspecified human being, to which reference is made by means of the demonstrative ‘the one’ («axí com cell...»); hyperbolic comparisons, where the ‘real’ element is given hyperbolically as having to the same or to a gr…
Comparing the physical activity patterns of 3-year-old Finnish and Australian children during childcare and homecare days
2014
AbstractLimited previous research has contrasted physical activity (PA) patterns in preschool children across different hourly patterns or segments of day, or adopted similar methodologies to compare the PA behaviors of children from different countries. The purpose of this study was to examine how the PA levels and patterns differed between 3- year-olds within and between childcare and homecare days in Finland and Australia.ActiGraph GT3X accelerometers were used to monitor 121 (80 Finnish, 41 Australian) children’s PA for five consecutive days.No significant country differences were observed in children’s daily total PA (light-tovigorous PA [LMVPA]), except that during childcare days Finn…
Power holders: one versus many. Leadership and elite theories
2016
‘Leadership’ and ‘elites’ are two crucial concepts that refer to individuals who hold power within a community. The aim of the article was to demonstrate to what extent the two concepts and theories are linked with each other in the literature. A quantitative and qualitative content analysis of the encyclopedic and dictionary entries demonstrates a divergence of approaches: on the one hand, a fundamental separation between the two theories, while on the other hand, a tendency to identify the one with the other. This shows the need for much more dialog between the frameworks of these two closely related phenomena.
Stress, Coping Strategies and Resources of Early Childhood Education Leaders during the COVID-19-Pandemic in Finland, Germany and Israel
2023
The exceptional circumstances during the COVID-19 pandemic in 2020-2021 caused unexpected challenges for the leaders in Early Childhood Education (ECE) centres. The range of measures implemented for preventing the infection from spreading reduced opportunities for face-to-face communication and changed the form of professional cooperation. All that has affected the working conditions and work well-being of the leaders. In this article we examine the ECE centre leaders' experiences regarding stress, their coping strategies and coping resources according to the Lazarus & Folkman (1984) stress model during the COVID-19-pandemic in Finland, Germany and Israel. The aim is to understand leaders' …
Combining Sequence Analysis and Hidden Markov Models in the Analysis of Complex Life Sequence Data
2018
Life course data often consists of multiple parallel sequences, one for each life domain of interest. Multichannel sequence analysis has been used for computing pairwise dissimilarities and finding clusters in this type of multichannel (or multidimensional) sequence data. Describing and visualizing such data is, however, often challenging. We propose an approach for compressing, interpreting, and visualizing the information within multichannel sequences by finding (1) groups of similar trajectories and (2) similar phases within trajectories belonging to the same group. For these tasks we combine multichannel sequence analysis and hidden Markov modelling. We illustrate this approach with an …
Psychometric Comparisons of Benevolent and Corrective Humor across 22 Countries: The Virtue Gap in Humor Goes International
2018
Recently, two forms of virtue-related humor, benevolent and corrective, have been introduced. Benevolent humor treats human weaknesses and wrongdoings benevolently, while corrective humor aims at correcting and bettering them. Twelve marker items for benevolent and corrective humor (the BenCor) were developed, and it was demonstrated that they fill the gap between humor as temperament and virtue. The present study investigates responses to the BenCor from 25 samples in 22 countries (overall N = 7,226). The psychometric properties of the BenCor were found to be sufficient in most of the samples, including internal consistency, unidimensionality, and factorial validity. Importantly, benevolen…
Reproducibility and concordance of 4 clinically developed programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) assays in triple-negative brea…
2020
Abstract Background Atezolizumab (an anti–PD-L1 antibody) has shown clinical activity alone or in combination with nab-paclitaxel in patients (pts) with first-line metastatic TNBC who have PD-L1 expression on their tumour-infiltrating immune cells (IC). We analysed the performance of 4 PD-L1 IHC assays for PD-L1 IC expression in TNBC. Methods Thirty archival TNBC tissue specimens were selected from a set of 107 based on PD-L1 IC expression per VENTANA SP142 ( 5%: 8 cases), to represent the distribution of PD-L1 IC–positivity in the pivotal atezolizumab studies (Emens et al., SABCS 2018; JAMA Oncol 2019). Serial histologic sections were stained with VENTANA SP142 and SP263, and DAKO 22C3 and…
Erratum to: ‘A cost and performance comparison of Public Private Partnership and public hospitals in Spain’
2016
Public-private partnership (PPP) initiatives are extending around the world, especially in Europe, as an innovation to traditional public health systems, with the intention of making them more efficient.There is a varied range of PPP models with different degrees of responsibility from simple public sector contracts with the private, up to the complete privatisation of the service. As such, we may say the involvement of the private sector embraces the development, financing and provision of public infrastructures and delivery services.In this paper, one of the oldest PPP initiatives developed in Spain and transferred to other European and Latin American countries is evaluated for first time…
Are go/no-go tasks preferable to two-choice tasks in response time experiments with older adults?
2015
Epub ahead of print 02/11/2015 Recent research has shown that, in response time (RT) tasks, the go/no-go response procedure produces faster (and less noisy) RTs and fewer errors than the two-choice response procedure in children, although these differences are substantially smaller in college-aged adults. Here we examined whether the go/no-go procedure can be preferred to the two-choice procedure in RT experiments with older adults (i.e. another population with slower and more error-prone responding than college-aged individuals). To that end, we compared these response procedures in two experiments with older adults (Mage = 83 years): a visual word recognition task (lexical decision) and a…
