Task persistence mediates the effect of children’s literacy skills on mothers’ academic help
2015
This longitudinal study aimed at examining the relationship between children's task persistence, mothers' academic help, and the development of children’s literacy skills (reading and spelling) at the beginning of primary school. The participants were 870 children, 682 mothers, and 53 class teachers. Data were collected three times – at the beginning and the end of Grade 1 and at the end of Grade 2. Better literacy skills predicted higher persistence in completing school tasks and, correspondingly, higher persistence was related to better subsequent skills. Also, lower task persistence at the end of Grade 1 corresponded to more frequent academic help from mothers in Grade 2. Moreover, child…
Why people engage in supplemental work: The role of technology, response expectations, and communication persistence
2021
Supported by various collaboration technologies that allow communication from any place or time, employees increasingly engage in technology-assisted supplemental work (TASW). Challenges associated with managing work and non-work time have been further complicated by a global pandemic that has altered traditional work patterns and locations. To date studies applying a TASW framework have focused mainly on individual uses of technology or connectivity behaviors, and not considered the potential team and social pressures underlying these processes. This study provides clarity on the differences between technology use and TASW and sheds light on the drivers of TASW in a work environment charac…
Math homework : Parental help and children’s academic outcomes
2019
In the present study, we examined the longitudinal relations between child-perceived parental help with math homework (i.e., support and control), children's math skills, and mother-reported task persistent behavior in homework situations. A total of 624 mother–child dyads were followed across Grade 6 and Grade 9, controlling for Grade 3 variables. At each measurement point, children completed math tests, and their mothers evaluated task persistence during homework. In Grades 6 and 9, children reported their perceptions of their parents’ help with math homework. First, the results showed that perceived support in Grade 6 predicted an increase in persistence during homework in Grade 9. Secon…
Prescription patterns of angiotensin-converting enzyme inhibitors for various indications: A UK population-based study
2018
AIM: Angiotensin‐converting enzyme inhibitors (ACEIs) are widely prescribed for several cardiovascular indications. This study investigated patterns of ACEI use for various indications. METHODS: A descriptive, retrospective population‐based study was conducted using data from the UK Clinical Practice Research Datalink. Patients starting ACEIs (2007–2014) were selected and ACEI indications were retrieved from electronically recorded medical records. Stratified by indication, we distinguished between persistent and nonpersistent ACEI use, considering a 6‐month interval between two prescription periods as a maximum for persistent use. Five‐year persistence rates for various indications were ca…
Assessment wine aroma persistence by using an in vivo PTR-ToF-MS approach and its relationship with salivary parameters
2019
To better understand wine aroma persistence, the nasal cavity of nine volunteers was monitored by Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) after they rinsed their mouths with three rosé wines (one control and the same wine supplemented with two tannin extracts) during four minutes. Wines were aromatised with a mixture of five target aroma compounds. Results showed that wine aroma persistence was highly compound-dependent: while esters disappeared very fast, other compounds such as linalool remained in the oral cavity for longer times after wine expectoration. A low effect of tannins (at 50 mg/L) on nasal cavity parameters was observed, with the exception for th…
Short-run and long-run persistence of bad health among elderly
2019
We study the health dynamics among older Americans using ten waves of the Health and Retirement Study following a spell-approach and a regression-based approach. The former is fully non parametric synthesizing the sequences of health status into a Health Persistence Index. The latter approach relies on a Latent Markov (LM) model capturing persistence in poor health by modelling time-varying unobserved heterogeneity. Our results show that only few elders experiences persistently a poor health status. The higher values of the index are consistently observed with the main socio-demo-economic risk factors. Moreover LM model indicates the existence of three unobserved groups differing in their p…
From the barbecue to the sauna: A comparative account of the folding of media reception into the everyday life
2021
How and why do people still get print newspapers in an era dominated by mobile and social media communication? In this article, we answer this question about the permanence of traditional media in a digital media ecosystem by analyzing 488 semi-structured interviews conducted in Argentina, Finland, Israel, Japan, and the United States. We focus on three mechanisms of media reception: access, sociality, and ritualization. Our findings show that these mechanisms are decisively shaped by patterns of everyday life that are not captured by the scholarly foci on either content- or technology-influences on media use. Thus, we argue that a non-media centric approach improves descriptive fit and ad…
A new measure for the attitude to mobility of Italian students and graduates: a topological data analysis approach
2022
AbstractStudents’ and graduates’ mobility is an interesting topic of discussion especially for the Italian education system and universities. The main reasons for migration and for the so called brain drain, can be found in the socio-economic context and in the famous North–South divide. Measuring mobility and understanding its dynamic over time and space are not trivial tasks. Most of the studies in the related literature focus on the determinants of such phenomenon, in this paper, instead, combining tools coming from graph theory and Topological Data Analysis we propose a new measure for the attitude to mobility. Each mobility trajectory is represented by a graph and the importance of the…
Microbial dynamics in durum wheat kernels during aging
2020
In the present work the microbial dynamics in wheat kernels were evaluated over time. The main aim of this research was to study the resistance of lactic acid bacteria (LAB) and yeasts associated to unprocessed cereals used for bread making during long term conservation. To this purpose four Triticum durum Desf. genotypes including two modern varieties (Claudio and Simeto) and two Sicilian wheat landraces (Russello and Timilia) were analysed by a combined culture-independent and -dependent microbiological approach after one, two or three years from cultivation and threshing. DNA based MiSeq Illumina technology was applied to reveal the entire bacterial composition of all semolina samples. T…
Étude de la biologie d'une messicole en régression: le bleuet (Centaurea cyanus L.)
2011
Agroecosystems are currently experiencing high biodiversity loss, in particular among the plant species specifically adapted to this habitat. This decline results from cropping systems that have been intensified in Western Europe since the 1950s. The cornflower (Centaurea cyanus L.), considered as emblem of the flora associated with traditional cereals, appears as a species that may be at risk and should be monitored. Indeed, cornflower can serve as a host to predators of crop pests and is strongly attractive for the pollinators. This study examines the biological factors that could potentially cause the decline of this species: spatial distribution, potential for growth, population's genet…
