工程监理话『诚信』

何谓“诚信”，既诚实，守信用。“‘诚’者从言，‘信’者亦从言。”诚者即诚实、坦诚、诚笃、诚恳也。‘信’者即信用、信任、信誉、信实、信义、信望也。国家拥有了“诚信”，即拥有了民心，拥有了既高尚又平凡的大众文化，拥有了国际地位和经济环境；企业拥有了“诚信”，即拥有了客户，拥有了企业文化形成的基本氛围和条件，拥有了后劲和生命力；一个人拥有了“诚信”，即拥有了正常人的基本行为准则和道德水准，拥有了信赖和朋友，拥有了广阔的活动领域。“诚信”对于一个人、一个企业、一个国家都是同等重要的。企业“诚信”的形成是…

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.

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 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.     

New new technologies: the future and the present of work in information and communication technology

This paper outlines a selection of technological and organisational developments in the information and communication technology (ICT) sector and analyses their likely challenges for workers and trade unions around the globe. It addresses the convergence of telecommunications and information technology, the related developments of ubiquitous computing, ‘clouds’ and ‘big data’, and the possibilities of crowdsourcing and relates these technologies to the last decades' patterns of value chain restructuring. The paper is based on desk research of European and international sources, on sector analyses and technology forecasts by, for instance, the European Union and Organisation for Economic Co‐operation and Development, and some national actors. These prognoses are analysed through the lens of recent research into ICT working environments and ICT value chains, identifying upcoming and ongoing challenges for both workers and unions, and outlining possible research perspectives.
