Genetic structure of wildcat (Felis silvestris) populations in Italy
2013
Severe climatic changes during the Pleistocene shaped the distributions of temperate-adapted species. These species survived glaciations in classical southern refuges with more temperate climates, as well as in western and eastern peripheral Alpine temperate areas. We hypothesized that the European wildcat (Felis silvestris silvestris) populations currently distributed in Italy differentiated in, and expanded from two distinct glacial refuges, located in the southern Apennines and at the periphery of the eastern Alps. This hypothesis was tested by genotyping 235 presumed European wildcats using a panel of 35 domestic cat-derived microsatellites. To provide support and controls for the analy…
Multi-Dimensional Pattern Matching with Dimensional Wildcards: Data Structures and Optimal On-Line Search Algorithms
1997
We introduce a new multidimensional pattern matching problem that is a natural generalization of string matching, a well studied problem1. The motivation for its algorithmic study is mainly theoretical. LetA1:n1,?,1:nd be a text matrix withN=n1?ndentries andB1:m1,?,1:mr be a pattern matrix withM=m1?mrentries, whered?r?1 (the matrix entries are taken from an ordered alphabet ?). We study the problem of checking whether somer-dimensional submatrix ofAis equal toB(i.e., adecisionquery).Acan be preprocessed andBis given on-line. We define a new data structure for preprocessingAand propose CRCW-PRAM algorithms that build it inO(logN) time withN2/nmaxprocessors, wherenmax=max(n1,?,nd), such that …
Durum wheat yield uncertainty under different tillage management practices and climatic conditions
2019
Abstract In the field of conservative agriculture, no-till (NT) management has been receiving increasing interest, with 45 million ha of land under no-till management in 1999 to 155 million ha in 2014. Up until now, no-till has only been observed to perform better under rainfed conditions, especially in dry climates mainly because the reduced tillage system retains more soil moisture. However, the adoption of alternative agricultural practices (NT) can be improved only if uncertain and consequent assumption of risk is well known and accepted. For these reasons, the aim of this research is (i) to define durum wheat suitability under NT soil management in terms of yield success probability an…
Epistemic governance in local policy debates : The case of entitlement to early childhood education and care in Finland
2019
In Finland, children below school age have enjoyed the right to attend subsidised full-time early childhood education and care (ECEC). However, the attendance rate in Finland is low in comparison to other Nordic countries. Furthermore, the entitlement was restricted to 20 h per week in 2016 unless the child’s parents work or study full-time or unless it is believed that the child will benefit from full-time ECEC. The debates concerning restrictions in ECEC entitlement in three municipal councils serve as the data for this study. By using the framework of epistemic governance, we identify three differing constructions of the ECEC’s societal functions in the municipal policy debates. The simi…
Intervention Programs to Promote the Quality of Caregiver–Child Interactions in Childcare: A Systematic Literature Review
2021
Sensitive caregiver–child interactions appear fundamental throughout childhood, supporting infants’ wellbeing and development not only in a familial context but in professional caregiving as well. The main aim of this review was to examine the existing literature about Early Childhood Education Context (ECEC) intervention studies dedicated to caregiver–child interaction, fostering children’s socioemotional developmental pathways. Studies published between January 2007 and July 2021 were identified in four electronic databases following PRIMSA guidelines. The initial search yielded a total of 342 records. Among them, 48 studies were fully reviewed. Finally, 18 of them met all inclusion crite…
Directly Observed Physical Activity among 3-Year-Olds in Finnish Childcare
2014
The main purpose of the study was to determine 3-year-olds’ physical activity levels and how these vary across season, gender, time of day, location, and the physical and social environment in childcare settings in Finland. A modified version of the Observational System for Recording Physical Activity in Children-Preschool (OSRAC-P) was used to measure physical activity levels and contextual variables (e.g., group composition, prompts) of children attending childcare centres. In total, 81 children (42 boys and 39 girls) were observed in autumn and in winter. Three-level linear regression analyses were used to assess differences between the seasons in the association between the context vari…
Update of the distribution and habitat use of the wildcat, pine marten and weasel in Sicily
2020
The wildcat (Felis silvestris), the pine marten (Martes martes) and the weasel (Mustela nivalis) are key members of the mammalian community in Sicily, actually performing the role of top predators and consequently influencing the trophic chain both in natural and agricultural areas. However, despite their protected status, very little information is available regarding their occurrence and ecology. Here, by verifying published studies, collecting personal observations and analyzing novel field data obtained by camera traps, we update their spatial distribution in Sicily, contributing to a better understanding of their habitat use and suggesting future research to improve our knowledge of th…
Subsidizing private childcare in a universal regime
2023
AbstractAll families in Finland have the freedom to choose between subsidized home care, universal public childcare, and private childcare. We study the impact of the introduction of private childcare subsidies in Finland. Private childcare subsidies have causal effects on take-up but no impact on home care or employment among women with small children. Instead, private services seem to crowd out public childcare. Private services have a socioeconomic gradient by mother’s education that steepens when the subsidy increases. Families’ preferences between home care, public childcare, and private childcare do not explain the result.
Mothers’ non-standard working and childcare-related challenges : A comparison between lone and coupled mothers
2016
Purpose – The purpose of this paper is to particularly focus on lone-mother families, comparing the childcare-related challenges experienced by working lone mothers and coupled mothers in three European countries in the context of a 24/7 economy and non-standard working hours (e.g. evening, night and weekend work). Design/methodology/approach – This study utilises survey data from Finnish, Dutch and British working mothers (n=1,106) collected as part of the “Families 24/7” research project. Multivariate regression analysis is used to analyse the associations between childcare-related challenges, maternal non-standard working, lone motherhood and country of residence. Findings – The results…
On the interpretability and computational reliability of frequency-domain Granger causality
2017
This Correspondence article is a comment which directly relates to the paper “A study of problems encountered in Granger causality analysis from a neuroscience perspective” (Stokes and Purdon, 2017). We agree that interpretation issues of Granger causality (GC) in neuroscience exist, partially due to the historically unfortunate use of the name “causality”, as described in previous literature. On the other hand, we think that Stokes and Purdon use a formulation of GC which is outdated (albeit still used) and do not fully account for the potential of the different frequency-domain versions of GC; in doing so, their paper dismisses GC measures based on a suboptimal use of them. Furthermore, s…
