Contact with Nature as Essential to the Human Experience
2021
Human contact with nature is more important than ever before considering the global confinement brought about by the COVID-19 pandemic, the increased urbanization of society, and increased rates of mental disorders and threats to human well-being. This article conveys the importance of contact with nature from three perspectives: historical, sociocultural, and scientific. These perspectives convey the many ways in which contact with nature is essential to human life, the multiple ways in which this is expressed, and the broad range of benefits this has. The case for preserving the natural environment continues to be made in light of the dangers of climate change, the deleterious effects of …
Unbiased Simultaneous Prediction Limits on Observations in Future Samples
2013
This paper provides procedures for constructing unbiased simultaneous prediction limits on the observations or functions of observations of all of k future samples using the results of a previous sample from the same underlying distribution belonging to invariant family. The results have direct application in reliability theory, where the time until the first failure in a group of several items in service provides a measure of assurance regarding the operation of the items. The simultaneous prediction limits are required as specifications on future life for components, as warranty limits for the future performance of a specified number of systems with standby units, and in various other app…
Stochastic Fatigue Models for Efficient Planning Inspections in Service of Aircraft Structures
2008
For important fatigue-sensitive structures of aircraft whose breakdowns cause serious accidents, it is required to keep their reliability extremely high. In this paper, we discuss inspection strategies for such important structures against fatigue failure. The focus is on the case when there are fatiguecracks unexpectedly detected in a fleet of aircraft within a warranty period (prior to the first inspection). The paper examines this case and proposes stochastic models for prediction of fatigue-crack growth to determine appropriate inspections intervals. We also do not assume known parameters of the underlying distributions, and the estimation of that is incorporated into the analysis and d…
Umowa deweloperska – początek biegu terminu na stwierdzenie wad budynku
2021
W artykule rozważona jest kwestia, który moment/które momenty należałoby uznać za początek biegu terminu na stwierdzenie wad jednego z przedmiotów umowy deweloperskiej, tj. budynku. Aby problem ten prawidłowo przeanalizować, w opracowaniu została przyjęta następująca struktura. W ramach zagadnień wstępnych przedstawiono, co należałoby uznać za przedmiot umowy deweloperskiej, jak prawnie należałoby zakwalifikować umowę deweloperską oraz czym różni się termin na stwierdzenie wady od terminu na jej zgłoszenie. Następnie rozważono, kiedy zaczyna biec termin na stwierdzenie wad budynku. Opracowanie wieńczy krótkie podsumowanie
Explaining classroom teachers’ attitudes towards inclusive education
2019
Teacher attitudes have been identified as an important resource when striving towards inclusive education as defined in the Salamanca Statement (1994). This study surveyed some key factors associated with teacher attitudes towards inclusion. The participants were 1,456 classroom teachers in Finnish primary schools who were asked about their readiness to include in their classrooms a student with a specified special educational need (SEN). The results were reviewed in association with some background variables, including workload concerns, evaluation of professional skills and the opportunity to get extra support if needed. The results show that classroom teachers’ positive attitudes towards…
