A review of the use of information and communication technologies for dietary assessment

Presently used dietary-assessment methods often present difficulties for researchers and respondents, and misreporting errors are common. Methods using information and communication technologies (ICT) may improve quality and accuracy. The present paper presents a systematic literature review describing studies applying ICT to dietary assessment. Eligible papers published between January 1995 and February 2008 were classified into four assessment categories: computerised assessment; personal digital assistants (PDA); digital photography; smart cards. Computerised assessments comprise frequency questionnaires, 24 h recalls (24HR) and diet history assessments. Self-administered computerised assessments, which can include audio support, may reduce literacy problems, be translated and are useful for younger age groups, but less so for those unfamiliar with computers. Self-administered 24HR utilising computers yielded comparable results as standard methods, but needed supervision if used in children. Computer-assisted interviewer-administered recall results were similar to conventional recalls, and reduced inter-interviewer variability. PDA showed some advantages but did not reduce underreporting. Mobile phone meal photos did not improve PDA accuracy. Digital photography for assessing individual food intake in dining facilities was accurate for adults and children, although validity was slightly higher with direct visual observation. Smart cards in dining facilities were useful for measuring food choice but not total dietary intake. In conclusion, computerised assessments and PDA are promising, and could improve dietary assessment quality in some vulnerable groups and decrease researcher workload. Both still need comprehensive evaluation for micronutrient intake assessment. Further work is necessary for improving ICT tools in established and new methods and for their rigorous evaluatio

Entrances and exits: changing perceptions of primary teaching as a career for men

Original article can be found at: http://www.informaworld.com/smpp/title~content=t713640830~db=all Copyright Informa / Taylor and Francis. DOI: 10.1080/03004430802352087The number of men in teaching has always been small, particularly in early childhood, but those that do come into teaching usually do so for the same reasons as women, namely enjoyment of working with children, of wanting to teach and wanting to make a difference to children's lives. However, in two separate studies, the authors have shown that on beginning teacher training in 1998, and at the point of leaving the profession in 2005, men and women tend to emphasise different concerns. This article will explore those differences and seek possible explanations for how men's views of teaching might be changing over time.Peer reviewe

Designing for Successful Learning: redesign of an IELTS preparation short course

While the Evening IELTS Preparation Short Course at London Metropolitan University has been running for several years, it has not benefited from a formal pre-determined syllabus. This paper reports on a redesign of the course which was undertaken to enable students doing it to finish with a better ability to achieve their required/desired IELTS exam score

Employment Prospects in a Commercially Viable Newfoundland Fishery: An Application of 'An Econometric Model of the Newfoundland Groundfishery'

An econometric model is utilized to simulate the effects of a policy change in which government financial assistance to a major Canadian marine fishery is withdrawn and the industry is placed on a commercially viable basis. Under near-ideal conditions of marketing and harvesting, harvesting employment would fall drastically, from approximately thirty thousand fishermen under the current regime to approximately six thousand. There would be a concomitant fall in seasonal fish plant employment, and a severe fall in those federal transfer payments (e.g., unemployment insurance) which are currently generated by extensive seasonal employment in both harvesting and processing sectors of the fishery. The policy analysis consists of simulations with a prototype econometric model which integrates the demand, processing, and harvesting sectors of the fishery. The essential components of the 1,000-equation model are described.Environmental Economics and Policy, Resource /Energy Economics and Policy,
