A Quantitative Analysis of the Thermoelastic Effect in CFRP Composite Materials
2010
In this study the thermoelastic signal from carbon fibre-reinforced plastic (CFRP) laminates is investigated. A comparison between the theoretical and experimental values of the thermoelastic signal is reported, with the theoretical predictions obtained from two different quantitative models. These models are based on the classic thermoelastic effect law extended to the case of orthotropic materials (by using the mesomechanical or bulk approach), and the modified law assuming that the surface resin-rich layer behaves as a strain witness of the laminate. It is found that the theoretical predictions of the two models can be strongly and differently influenced by the intrinsic orthotropy of ca…
Evaluation of web reinforcements in prestressed concrete box girders through shear-transverse bending domains
2020
In concrete box girders, the amount and distribution of reinforcements in the webs have to be estimated considering the local effects due to eccentric external loads and cross-sectional distortion and not only the global effect due to the resultant forces of a longitudinal analysis: shear, torsion and bending. This work presents an analytical model that allows designers to take into account the interaction of all these effects, global and local, for the determination of the reinforcements. The model is based on the theory of stress fields and it has been compared to a 3D finite element analysis, in order to validate the interaction domains. The results show how the proposed analytical mode…

Associations of Work-Family Conflict with Family-Specific, Work-Specific, and Well-Being-Related Variables in a Sample of Polish and Ukrainian Adults…
2022
The conflict between work and family demands increased during the COVID-19 pandemic due to changes in lifestyle related to the lockdown. This study examines the associations between work-family conflict (WFC) and family-work conflict (FWC) with work-specific, family-specific, and well-being-related variables during the second wave of the COVID-19 pandemic. The results may be used in practice to improve the well-being of employees by adjusting home-based work and family areas of life to dynamic changes during the pandemic. The sample of 736 adults from Poland (53.26%) and Ukraine (46.74%), aged between 19 and 72 (M = 39.40; SD = 10.80), participated in the study. The cross-sectional study wa…
Bending Work Time: Curvilinear Relationship Between Working Time Dimensions and Psychological and Somatic Symptoms.
2020
Objectives Study examines the curvilinear associations of working time dimensions (working hours, time pressure, work schedules, and control of work time and pace) on psychological and somatic symptoms. Methods Representative Finnish Quality-of-Work-Life Surveys conducted in 2003, 2008 and 2013 were restricted to those (N=11,165) regularly working over 10h/week with more than one-year tenure in their job. Generalised additive models were utilised in analysis. Results Working hours had U-shaped relationships with psychosomatic symptoms, while time pressure had a threshold effect. Work pace control had linear effect. The effects of work time control and work schedules were insignificant. Ther…
Ponnistelujen ja palkkioiden epäsuhdan sekä ylisitoutuneisuuden yhteys työn intohimoon
2017
Tutkimuksen tarkoituksena oli lisätä tietoa työssä ilmenevien ponnistelujen ja palkkioiden epäsuhdan sekä ylisitoutuneisuuden yhteyksistä kahteen erilaiseen työn intohimoon: harmoniseen ja pakonomaiseen. Tutkimus kohdistui 270 suomalaiseen toimihenkilöön. Tutkittavista 220 oli miehiä (81.5%) ja tutkittavien keski-ikä oli 42 vuotta (kh 3.3, vaihteluväli 34—47). Hierarkkisen lineaarisen regressioanalyysin tulokset osoittivat, että ponnistelujen ja palkkioiden epäsuhta selitti korkeaa harmonista työn intohimoa. Ylisitoutuneisuus selitti vähäistä harmonista työn intohimoa ja korkeaa pakonomaista työn intohimoa. Ylisitoutuneisuus ei muuntanut ponnistelujen ja palkkioiden epäsuhdan yhteyttä kumpa…
Foneettisten piirteiden ja vieraan aksentin yhteydestä suomen kielessä
2018
Tapaustutkimuksemme tarkoituksena on selvittaa muutaman foneettisen piirteen ja vieraan aksentin yhteytta suomen kielessa. Analysoimme ilmiota kuulijatestilla, akustisin mittauksin ja kirjoittajien tekemin kuulonvaraisin havainnoin. Puhujina ovat varsin edistyneet suomenpuhujat, jotka puhuvat suomea toisena tai vieraana kielenaan. Tuloksemme antavat uutta tietoa vieraan aksentin ja foneettisten piirteiden yhteyksista seka tarjoavat avauksia jatkotutkimukselle. Tutkitut piirteet ovat pitkien vokaalien etaisyydet, aannekestot, perustaajuuden (f0) vaihteluvali, f0:n vaihtelun jyrkkyys ja keskihajonta seka artikulaationopeus. Tuloksemme osoittavat, etta kaikilla piirteilla on yhteys vieraaseen …
Wsparcie i radzenie sobie ze stresem jako moderatory związku stresu i jakości życia osób transpłciowych
2018
This study was conducted in order to verify the role of social support and coping strategies as moderators of the relationship between perceived stress and the subjective well-being of transgender people, which is lower than cisgenders’ people. 355 people took part in this study (124 transgender people and 231 cisgender people) between age of 18 and 53. Subjective well-being has been operationalized using the Satisfaction With life Scale SWLS. Measurement of the perceived stress was made using the Perceived Stress Scale PSS-10. Coping strategies were examined using the Mini-COPE inventory. Additionally, two subscales of the Berlin Social Support Scales BSSS were used to measure received and…
Transnational ties: Resource or stressor on Peruvian migrants' well‐being?
2020
This paper explores the role of types and the intensity of transnational ties for migrants' well‐being from a global perspective. Based on a literature review, two competing hypotheses are formulated—transnational resources versus transnational stress—according to which transnational ties have either a positive or a negative effect on migrants' well‐being. Drawing on data from a large‐scale survey of Peruvian migrants worldwide, this paper examines the strength and direction of the relationship between Peruvian migrants' transnational ties and poor well‐being, the latter measured as depression/loneliness as a principal concern. While the multivariate regression results do not support the tr…
