Abstract
Austin Industries, Inc., and Wyatt Cafeterias Inc., have “bet the ranch” on employee ownership. Through stock ownership plans and participative management, employees at the two Texas‐based companies are playing a more direct role in the decisions that increase productivity and profitability.

Abstract
Purpose
The purpose of the paper is to determine the effects of a hypocaloric diet with a low-glycaemic index (GI) on weight loss and postprandial blood glucose and assess both the satiety and palatability of the diet.
Design/methodology/approach
A clinical trial was conducted with ten women (mean age: 38.8±11.3 years; body mass index: 27.2±3.5 kg/m2) submitted to a hypocaloric diet, assessments were performed at baseline and after seven days of treatment.
Findings
Significant reductions were found in body weight (1.1±0.7 kg; p=0.001), triccipital skinfold (2.87±3.24 mm; p=0.021) and waist circumference (3.6±4.8 cm; p=0.041). Mean fasting and postprandial blood glucose values were 88.7±6.1 mg/dL and 91.6±9.6 mg/dL, respectively. Responses regarding satiety and palatability of the low-GI diet were predominantly “extremely satisfied” and “I liked it very much,” respectively, for all meals and throughout all seven days of the study.
Originality/value
The present study demonstrated the benefits of a low-GI diet with regard to weight loss, blood glucose control and satiety. The diet proved to be palatable, which could favor compliance with long-term treatment.

Abstract
Purpose
The aim of this literature review is to summarise and synthesise the research base concerning childhood obesity and physical activity, particularly in relation to teachers and schools and within a policy context of the UK. The review investigates childhood obesity, physical activity, physical education, the role of teachers, the role of schools and physical activity in the classroom.
Design/methodology/approach
A literature review was undertaken involving selection of primary research and other systematic reviews. A computer search was performed using a combination of keywords including: obesity, prevention, intervention, preventive, teachers, schools, healthy schools, role models, physical activity, physical education, active school, active classroom. The review also includes samples of media coverage of the issue.
Findings
This review highlights the complex and ambiguous nature of the evidence in relation to this important contemporary issue.
Originality/value
A limited understanding of childhood obesity is evident from the review and this precludes definitive conclusions in relation to almost all aspects of the agenda. More quality research is needed in almost all areas of the topic, including areas such as the engagement of schools and teachers.

Abstract
In 1969, Warren Nutter left the University of Virginia Department of Economics to serve as the Assistant Secretary of Defense for International Security Affairs in the Nixon administration. During his time in the Defense Department, Nutter was deeply involved in laying the groundwork for a military coup against the democratically elected president of Chile, Salvador Allende. Although Nutter left the Pentagon several months before the successful 1973 coup, his role in Chile was far more direct than the better-known cases of Friedrich Hayek, Milton Friedman, James Buchanan, and Arnold Harberger. This chapter describes Nutter’s role in Chile policymaking in the Nixon administration. It shows how Nutter’s criticisms of Henry Kissinger are grounded in his economics, and compares and contrasts Nutter with other economists who have been connected to Pinochet’s dictatorship.

Abstract
Purpose
This study aims to investigate the effectiveness of a teaching method (TLS (Teaching/Learning Sequence)) based on a social constructivist paradigm on students' conceptualisation of classification of food.
Design/methodology/approach
The study compared the TLS model developed by the researcher based on the social constructivist paradigm with the Regular Teaching Method (RTM) in use in the school. Students exposed to the TLS model constituted the experimental group, while the students exposed to the RTM constituted the control group. The design was a pre‐test/post‐test control design with a retention‐phase.
Findings
Results before intervention revealed gross misconceptions of pupils' classification of food, while after intervention there was significant improvement of the TLS over RTM.
Research limitations/implications
The context of the research is limited to students' conceptualisation of classification of food items into the five classes of food, i.e. carbohydrate, protein, fat, vitamin, and mineral. Although food group allocation was validated from previous literature, it is still a potential limitation as a single food item may contain more than one nutrient, which makes its classification in a single food class difficult.
Practical implications
Understanding whether students' conceptualisation of classes of food is changed by the information they received by established methods would be valuable when devising methods of delivering nutrition education.
Social implications
Food provision in schools must support the messages that pupils receive through the formal curriculum.
Originality/value
Education can be immensely helpful in the pursuit of better understanding by children regarding healthy eating.
