Measuring diet in the 21st century: use of new technologies
The advent of the internet and smartphone technology has allowed dietary assessment to reach the 21st century! The variety of foods available on the supermarket shelf is now greater than ever before. New approaches to measuring diet may help to reduce measurement error and advance our understanding of nutritional determinants of disease. This advance provides the potential to capture detailed dietary data on large numbers of individuals without the need for costly and time-consuming manual nutrition coding. This aim of the present paper is to review the need for new technologies to measure diet with an overview of tools available. The three main areas will be addressed: (1) development of web-based tools to measure diet; (2) use of smartphone apps to self-monitor diet; (3) improving the quality of dietary assessment through development of an online library of tools. A practical example of the development of a web-based tool to assess diet myfood24 (www.myfood24.org) will be given exploring its potential, limitations and challenges. The development of a new food composition database using back-of-pack information will be described. Smartphone apps used to measure diet with a focus on obesity will be reviewed. Many apps are unreliable in terms of tracking, and most are not evaluated. Accurate and consistent measurement of diet is needed for public health and epidemiology. The choice of the most appropriate dietary assessment method tends to rely on experience. The DIET@NET partnership has developed best practice guidelines for selection of dietary assessment tools, which aim to improve the quality, consistency and comparability of dietary data. These developments provide us with a step-change in our ability to reliably characterise food and nutrient intake in population studies. The need for high-quality, validated systems will be important to fully realise the benefits of new technologies.

Examining the mediating role of dynamic capabilities in the relationship between information and communication technologies and sustainable performance
Purpose
Information and communication technologies (ICTs) enable firms to improve their processes to remain competitive and profitable in today’s market. These demands not only value economic results but also social impact and environmental care. In other words, firms must achieve sustainable performance. However, to take on these new sustainability challenges, firms must have dynamic capabilities to take advantage of highly changing technology. Thus, this study aims to examine the mediating role of dynamic capabilities in the relationship between ICT and sustainable performance.
Design/methodology/approach
This study was empirical, associative and explanatory, following a latent variable design. The sample of the study consisted of partners, founders, executives and promoters from 102 Colombian new technology-based firms selected through purposive non-probabilistic sampling. Variance-based structural equation modeling or partial least squares was used for the statistical data analysis.
Findings
A higher-order model was tested, corroborating that ICT was composed of two dimensions (use and acquisition), dynamic capabilities were composed of three dimensions (absorption, innovation and adaptation), while sustainable performance showed a unidimensional structure. As for the research hypotheses, all the direct effects were supported, as well as the mediating effect of dynamic capability in the relationship between ICT and sustainable performance, this being a complementary mediation.
Originality/value
This study highlights the importance of dynamic capabilities for firms today, especially those working with high levels of technology. Also, considering the results obtained, firms must implement better strategies in the acquisition and use of technology to improve their sustainable performance in dynamic and uncertain environments.

Being a teacher in the 21st century : a critical New Zealand research study
This book provides scholars, teacher educators, as well as reflective school leaders and teachers with valuable insights into what it is to be a teacher in the 21st century. It does so by presenting original research based on a study of several New Zealand schools between 2013 and 2015, and in particular, a focussed study of four of those schools in 2015. The book draws on the findings to take stock of some of the central manifestations of 21st-century learning, especially digital pedagogies and the collaborative practices associated with teaching and learning in modern learning environments. It reflects on the mental shifts and sometimes-painful transitions teachers and leaders are making and experiencing as they enter uncharted waters, moving from traditional classroom practices to ones that emphasise collaboration, teamwork and the radical de-centring of their personal roles. It outlines a blueprint for understanding how to navigate these changes, and describes and explains the nature of pedagogical shifts apparent in digital classrooms and modern learning environments.

New mobile methods for dietary assessment: review of image-assisted and image-based dietary assessment methods
For nutrition practitioners and researchers, assessing dietary intake of children and adults with a high level of accuracy continues to be a challenge. Developments in mobile technologies have created a role for images in the assessment of dietary intake. The objective of this review was to examine peer-reviewed published papers covering development, evaluation and/or validation of image-assisted or image-based dietary assessment methods from December 2013 to January 2016. Images taken with handheld devices or wearable cameras have been used to assist traditional dietary assessment methods for portion size estimations made by dietitians (image-assisted methods). Image-assisted approaches can supplement either dietary records or 24-h dietary recalls. In recent years, image-based approaches integrating application technology for mobile devices have been developed (image-based methods). Image-based approaches aim at capturing all eating occasions by images as the primary record of dietary intake, and therefore follow the methodology of food records. The present paper reviews several image-assisted and image-based methods, their benefits and challenges; followed by details on an image-based mobile food record. Mobile technology offers a wide range of feasible options for dietary assessment, which are easier to incorporate into daily routines. The presented studies illustrate that image-assisted methods can improve the accuracy of conventional dietary assessment methods by adding eating occasion detail via pictures captured by an individual (dynamic images). All of the studies reduced underreporting with the help of images compared with results with traditional assessment methods. Studies with larger sample sizes are needed to better delineate attributes with regards to age of user, degree of error and cost.

Entrepreneurial networks, geographical proximity, and their relationship to firm growth: a study of 241 small high-tech firms
Start-up firms in high-tech sectors normally engage in networking to overcome their lack of resources, knowledge, and competence constraints. A newly established firm’s network can provide a source of social capital, which may enhance its growth prospects. In this study, 241 new technology-based firms (NTBFs) in Sweden are studied during their early formative years to investigate how entrepreneurial networks and the geographical proximity to actors in these networks affect the early performance of these firms in terms of growth. Three underlying factors are identified in the analysis: geographical proximity and professional and consultative networks. This study finds that professional networks have a positive and significant effect on NTBFs’ growth, which indicate that utilizing these networks benefit the growth of both young and growing firms. NTBFs in initial stages can acquire business opportunities by constructing professional networks. In addition, several formal links positively affect growth, such as regional business partners, incubator networks, and links to universities.

Digital art
Digital technology has revolutionized the way we produce and experience art today. Not only have traditional forms of art such as printing, painting, photography and sculpture been transformed by digital techniques and media, but entirely new forms such as internet art, software art, digital installation and virtual reality have emerged as recognized artistic practices. Christiane Paul surveys the developments in digital art from its appearance in the 1980s to the present day and looks ahead to what the future may hold. Drawing a distinction between work that uses digital technology as a tool to produce traditional forms and work that uses it as a medium to create new types of art, she discusses the key artists and works. The book explores themes addressed and raised by these artworks, such as viewer interaction, artificial life and intelligence, political and social activism, networks and telepresence, and issues surrounding the collection, presentation and preservation of digital art. This third, expanded edition investigates key areas of digital art practice that have gained in prominence in recent years, including the emergence and impact of locative media, interactive public installation, augmentive and mixed reality, social networking, and file-sharing and tablet technologies.
