Numerical analysis of the mechanical response of wood glulam beams reinforced through the thickness by FRP rods
2009
The modern use of through-thickness reinforcement in wood glulam (glued laminated) beams, bridging the potential delamination crack faces, has shown to be an effective technological solution to improve their interlaminar fracture strength. In this paper, the behaviour of wood glulam beams is investigated from an experimental and numerical point of view, comparing the mechanical response of unreinforced and reinforced (by FRP rods) beams subjected to four points bending tests. For the numerical analysis, a simple two-phases (joint and reinforcement) interface model has been formulated and implemented in a finite element code. In particular, the classical interface model for adhesive joint, a…
The Relationship between Knowledge Characteristics’ Fit and Job Satisfaction and Job Performance: The Mediating Role of Work Engagement
2020
Knowledge workers are highly valued by organizations, but there is a lack of evidence about the role of work engagement in the satisfaction and performance of these workers. Harmonization and Person&ndash
Differential Effects of Mindfulness-Based Intervention Programs at Work on Psychological Wellbeing and Work Engagement.
2021
Two different mindfulness-based interventions were deployed in a sample of white-collar workers to explore the differential effects on different facets of mindfulness, dimensions of psychological wellbeing, work engagement, performance, and stress of a participant. A total of 28 participants completed one of the different programs, and their results were compared between groups and against 27 participants randomly allocated to a waiting list control group. Results suggest both mindfulness intervention programs were successful at increasing the levels of psychological wellbeing, work engagement, and performance of the participants, as well as decreasing their levels of stress. Significant di…
Differential effects of workaholism and work engagement on the interference between life and work domains
2018
This study analyzed the differences between workaholism and work engagement in relation to their influence on work–life interference. Workaholism is an addiction to work, characterized by obsessive attitude towards job, whereas work engagement concerns a positive pattern of thoughts and feelings about one’s job; these two constructs thus represent pathological and healthy forms of heavy work investment, respectively. As a consequence, it was expected that workaholism and work engagement would have different effects on perceived interference between work and life domains. We assessed levels of workaholism, work engagement, work-to-life interference, and life-to-work interference in a sample …
Job Resources and Work Engagement: Optimism as Moderator Among Finnish Managers
2014
The aim of the present study was to investigate the moderating role of optimism in the relationship between job resources (organizational climate, job control) and work engagement among Finnish young managers (N = 747). Hierarchical regression analyses showed that both job resources and optimism exerted a positive effect on work engagement and its three dimensions of vigor, dedication, and absorption. The moderation results showed that optimism can diminish the negative impact of low job resources on work engagement. These findings provide evidence to the importance of including personal resources in future research conducted on motivational process. Additionally, these findings provide sig…
The XENON1T Dark Matter Experiment
2017
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented. © 2017, The Author(s).
XENON1T Dark Matter Data Analysis: Signal Reconstruction, Calibration and Event Selection
2019
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6\,$GeV/$c^2$ scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 metric tons of liquid xenon in the target. A one metric $\mathrm{ton}\times\mathrm{year}$ exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In pa…
Game of Thrones -pelin Let's Play -videot ja populaarikulttuurin vastaanotto esityksenä
2019
Suositun Valtaistuinpeli (Game of Thrones) -tv-sarjan myötä George R. R. Martinin Tulen ja jään laulu -kirjasarjaan perustuvasta transmediauniversumista on tullut ilmiö, jolla on faneja huomattavasti laajemmin kuin vain fantasiaharrastajien piirissä. Tässä artikkelissa pyrin selvittämään tapoja, joilla ihmiset kokevat Valtaistuinpelin maailman, hahmot ja tapahtumat, ja sitä, miten he niitä tulkitsevat ja suhteuttavat omaan elämänkokemukseensa. Hypoteesina on, että Let’s Play -videot tarjoavat hedelmällisen aineiston pelien ja yleisemmin populaarikulttuurin synnyttämien kokemusten tarkasteluun.Tutkimusmenetelmänäni on Game of Thrones -videopelistä tehtyjen Let’s Play -videoiden analysointi e…
Testing a methodology to improve organizational learning about crisis communication
2011
Purpose – The purpose of this paper is to introduce a measurement system with performance indicators to improve organizational learning about crisis communication by public organizations. The tool can be used to conduct a preparedness audit or to evaluate communication performance in a real situation or in an emergency exercise. Evaluation is part of the strategic planning and development of crisis communication. The construction of the instrument and its theoretical underpinnings are first explained, after which the series of empirical tests that were implemented to scrutinize the clarity and appropriateness of the indicators as well as the usability of the instrument are presented. Design…
The role of personal and relative job performance in promotion decisions
2021
This study employs personnel data from a large university to examine how supervisors utilize information on employees' job performance in promotion decisions. The study shows that better-performing employees are rewarded with promotions as a higher output of peer-reviewed publications and better quality of research output are associated with a higher probability of being promoted. The study also shows that supervisors compare their subordinates' job performance when deciding on promotions: employees who outperform their colleagues in terms of research output and research quality are more likely to be promoted. Subsequently, the study provides evidence to support the key premise of the tourn…
