Hydrogels for Three-Dimensional Ionizing-Radiation Dosimetry

2021

Radiation-sensitive gels are among the most recent and promising developments for radiation therapy (RT) dosimetry. RT dosimetry has the twofold goal of ensuring the quality of the treatment and the radiation protection of the patient. Benchmark dosimetry for acceptance testing and commissioning of RT systems is still based on ionization chambers. However, even the smallest chambers cannot resolve the steep dose gradients of up to 30–50% per mm generated with the most advanced techniques. While a multitude of systems based, e.g., on luminescence, silicon diodes and radiochromic materials have been developed, they do not allow the truly continuous 3D dose measurements offered by radiation-se…

Microbial dynamics during green Sicilian table olive fermentations

2009

The production of green table olives is traditionally a spontaneous fermentation carried out by indigenous microflora. Variability of microbial raw material may result in changes in the qualitative aspects of final products (Silvestri et al., 2009). Table olives of five different green table olive cultivars (four Sicilian Brandofino, Castriciana, Nocellara del Belice and Passalunara and the Spanish Manzanilla) were produced according to a semi-industrial technology, in which lactic acid bacteria (LAB) role is partially replaced by lactic acid addiction. Transformation processes were studied by a combined strategy consisting of chemical, microbiological and sensory analyses. Yeasts harboured…

Taloyhtiöistä tulevaisuuden energiatuottajia : muutospolut vuoteen 2035 ja murrosareena tiedon yhteistuotannon menetelmänä

2020

Noin neljännes Suomen asuntokannasta koostuu taloyhtiöistä. Niistä merkittävä osa tarvitsee lähivuosina korjauksia, joiden avulla voidaan kehittää rakennuskannassa tapahtuvaa hajautettua energiantuotantoa esimerkiksi aurinkopaneelien ja lämpöpumppuratkaisujen avulla. Vuonna 2018 voimaan tullut EU:n energiayhteisösääntely luo yhdessään meneillään olevat kansallisten sääntelymuutosten kanssa perustan, jonka varassa taloyhtiöt voivat vahvistaa kansalaisten energiantuottajaroolia tulevaisuudessa. Murros taloyhtiöiden kestävään energiantuotantoon on haaste, joka edellyttää useiden yhteiskunnan osa-alueiden näkökulmien ja toimijoiden kokoamista yhteen. Tätä tavoitetta varten järjestettiin vuonna …

Customer Environmental Values and Their Contribution to Loyalty in Industrial Markets

2016

Concern over the effect of industries on the natural environment is growing on a multitude of levels. This study examines the effects of how perceptions of (a) environmental values, (b) green image and (c) perceived value of industrial customers influence their loyalty towards suppliers in existing relationships, and how the length of B2B relationships may moderate these linkages. A conceptual framework is developed and data are collected from a global sample (N =121) of B2B customers. We find that both green image and perceived value have a direct positive link with customer loyalty and that environmental values are positively linked to the green image of the supplier. Moreover, the effect…

Relationships Between Career Indecision, Search for Work Self-Efficacy, and Psychological Well-Being in Italian Never-Employed Young Adults.

2017

Although different studies have investigated career choices as cognitive acts of decision-making, non-cognitive components also play an important role. The study tries to develop an empirically based model of career decision-making process linking cognitive (search for work self-efficacy - SWSE) and non-cognitive (psychological well-being - PWB) components. In particular, the study investigates, among 148 never-employed Italian young adults, to what extent the relationship between SWSE and career indecision in terms of lack of readiness (LoR) can be explained by their common relationship with PWB. Results highlighted that SWSE is negatively associated with LoR when considered in absence of …

Deciding on the direction of career and life : personal goals, identity development, and well-being during the transition to adulthood

2017

Humans make efforts to manage their lives, and they do this by setting goals and making decisions. When they commit to their decisions, they construct their identity. This research aimed to study young people’s personal goal contents and appraisals, and how these constructs were related to identity and career identity development and subjective well-being. The theoretical basis of this research comprised the life-span model of motivation (Nurmi, 2004; Salmela-Aro, 2009), the conceptualisation of phase- adequate engagement (Dietrich, Parker, & Salmela-Aro, 2012), and the dual-cycle model of identity development (Luyckx, Goossens, Soenens, & Beyers, 2006; Luyckx et al., 2008). The data for th…

Rules of Engagement: Family Rules on Young Children’s Access to and Use of Technologies

2018

This chapter reports on a study conducted in seven countries in which young children’s (aged under 8) digital practices in the home were examined. The study explored family practices with regard to access to and use of technologies, tracing the ways in which families managed risks and opportunities. Seventy families participated in the study, and interviews were undertaken with both parents and children, separately and together, in order to address the research aims. This chapter focuses on the data relating to parental mediation of young children’s digital practices. Findings indicate that parents used a narrow range of strategies in comparison to parents of older children, primarily becau…

Meeting the WHO 24-h guidelines among 2–6-year-old children by family socioeconomic status before and during the COVID-19 pandemic : a repeated cross…

2023

Background The World Health Organization (WHO) has developed guidelines for 24-h physical activity (PA), sedentary behaviour and sleep for young children. Lower socioeconomic status (SES) has been linked to a lower likelihood of meeting these guidelines. The outbreak of the novel coronavirus disease (COVID-19) raised concerns about young children’s opportunities to meet the guidelines. The study focused on the prevalence of meeting the WHO’s 24-h guidelines on screen time (ST), PA and sleep among 2–6-year-old children, in association with family SES, before COVID-19 outbreak in 2019, and during the pandemic in 2020 and 2021 in Finland. Methods Data were collected at three timepoints by an o…
