Diffusion and usage of public e-services in Europe: An assessment of country level indicators and drivers

We analyze the state of the art of indicators on e-government, e-health, e-procurement and e-participation. We survey the main methodological properties of these indicators, and highlight their heuristic potential. Further, we address empirically the issue of the explanation of the availability scores, i.e. how the supply of the various e-services in each country is affected by political, institutional and socio-economic differences, and is followed by actual usage. The econometric analysis uncovers the importance of broadband penetration and higher education as drivers for most of the types of e-services and users (citizens and businesses). Moreover, a corruption-free and agile public sector proves to be an important pre-condition for more effective supply and usage. Despite data limitations and the complexity of the underlying diffusion phenomena, our study is the first truly longitudinal contribution aimed at disentangling the common drivers of such an important phenomenon – the e-services availability and usage across European countries. As such, this work appears useful to inform the policy debate and practice, in a phase characterized by a prospective reorientation of the public e-services provision and policy agenda.     

The locating of emotion within a creative, learning and product orientated design and technology experience: person, process, product

Within this paper, a conceptualised triadic schema is hypothesised for locating emotion within a creative, learning and product orientated Design and Technology experience. The research is based upon an extensive literature review that has been synthesised and juxtaposed with the broad aspirational aims of the subject. The schema, based upon abductive reasoning and grounded theory, ultimately conceptualises the overarching theme of emotion within a creative, learning and product orientated Design and Technology experience within the Primary and Secondary stages of England’s education system. The triadic schema offers an additional opportunity in meta-theorising how the broad aspirational aims of the subject, as outlined in the English national curriculum statement of importance for Design and Technology, can be achieved through recognising the powerful overarching concept of emotion within three emerging domains: Person, Process and Product. The central tenet of this paper is the recognition of emotion within a triadic schema for meta-theorising the place of emotion within a creative, learning and product orientated Design and Technology experience. David Spendlove was previously a senior teacher in secondary education before moving into Higher Education and is now the subject leader for Design and Technology at the University of Manchester. He co-edits both Design and Technology Education: An international Journal and the DATA international research conference proceedings. He is a director of the Design and Technology Association and his research interests are broadly based around learning, pedagogy, creativity, emotion and gender.     

Improving the food environment in kindergartens and schools: An overview of policies and policy opportunities in Europe

Childhood obesity and unhealthy nutrition are high on the European policy agenda because of their association with chronic diseases and due to the related social and economic burden. In 2014, the EU Action Plan on Childhood Obesity 2014–2020 was launched with an overarching goal to halt the rise of overweight and obesity in children by the year 2020. To facilitate the implementation of the Action Plan, the Directorate-General for Health and Food Safety of the European Commission provided support to bring together 25 Member States plus Norway for a Joint Action on Nutrition and Physical Activity (JANPA). The current paper is based on the results of JANPA and presents the explored policy options to improve children's nutrition by targeting the food environment in and around kindergartens and schools. We conclude that for effective actions countries need to combine various mutually reinforcing policies in parallel, including the provision of healthy foods, lowering the availability of unhealthy foods, restricting marketing, and promoting education. Success will depend on the coherence of messages and on the engagement of a wide range of stakeholders and sectors. Evaluation should be carefully designed, using indicators of progress towards the goal of improving diet and reducing obesity in children.     

Firms' Growth,Size and Age: A Nonparametric Approach

This paper offers empirical evidence of firm failurerates as well as the mean of the distribution ofrealized growth rates, distinguishing between thesample of non-failing firms and the sample of allfirms, failing and non-failing. Attention is directedat identifying a set of characteristics, in particularthe size and age of firms, systematically related tothe patterns of firm growth and exit, using a panel ofSpanish manufacturing firms. The two maincontributions of the paper are the use ofnonparametric techniques and the analysis of issuesignored in other studies like theregression-to-the-mean bias and the measurement oflearning effects. We find evidence that failure ratesand the mean growth rate of successful firms declinewith size and age. When failing firms are integrated,there are no significant differences in the meangrowth rate across the age and size of firms.Regression-to-the-mean does not prove to be asubstantial factor behind the negative relationshipbetween size and growth of surviving firms.

Assessing nutritional status and nutrition-related knowledge,attitudes and practices of Albanian schoolchildren to support school food and nutrition policies and programmes

In Albania, many children exhibit poor nutritional status, have unhealthy diets and inadequate physical activity. Yet, comprehensive studies on the nutritional status, food and nutrition knowledge, attitudes and practices (KAP) are largely non-existent for Albanian school-age children.To fill these important gaps, a nationwide survey was conducted in Albania in 2017–2018 to assess the nutritional status and the nutrition-related KAP of Albanian school-aged children.The study consisted of a nationally representative sample of 7578 Albanian schoolchildren from all regions of the country. In addition, 6810 parent questionnaires were collected, along with interviews with the directors of all involved schools, 311 teachers and 53 key informants representing local authorities in all districts of Albania. Data collection consisted of anthropometric measurements of children and structured questionnaires administered to children, their parents, teachers, school directors, and key informants.The survey is unique in both the scope of the respondents involved, and in the breadth of content area covered, and as such, makes an important contribution not only to Albania, but also to the field of research in food, health and nutrition for school-age children.This paper presents the preliminary findings from the KAP survey that will help influence policies for actionable advancement on the commitments and priorities of Albania to improve food security and nutrition. In particular, the study findings will support the development of a national school food and nutrition programme in Albania embedded into the local food system and the design of food and nutrition educational materials and campaigns to promote healthy diets and practices among both school-age children and the Albanian population.

The gap not only closes: Resistance and reverse shifts in the digital divide in Russia

The reduction of the digital divide due to the availability of the Internet and the improvement of skills is accompanied by reverse and resistance trends associated with the influence of socio-demographic and economic characteristics of users. In this paper, we estimate the volume and dynamics of the digital divide in access and use of the Internet in Russia by key social groups according to a longitudinal survey for 2008–2018. We found that along with the reducing of the digital divide, its gaps still remain. The greatest polarization is associated with the income, age, and type of residence of the respondents. The most vulnerable social groups on access to ICTs and Internet use are the low-income, the elderly, citizens with disabilities, and those living in rural areas. The reverse shifts in the digital divide were recorded mainly in relation to the Internet usage by age between the middle-age and youth and by gender. In addition, we pointed out the most resistance social groups to reduce the digital divide in the period under review, in particular, by income and type of residence of the respondents. The findings contribute to an understanding of the dynamics and social consequences of the digital divide and can be taken into account in social policy and measures.
