Abstract
Purpose
This paper aims to address shortcomings of current tiltrotor designs, such as the small aspect ratio of the wings, large download and the close proximity of the rotor tips. It also aims to avoid the complex transition of tiltrotors to normal airplane mode.
Design/methodology/approach
This design combines tiltrotor and tiltwing aircraft designs into a hybrid that is augmented by active flow control, using a gimbaled channel wing for attitude control in hover.
Findings
The proposed hybrid design is based on experimental results of components that were tested individually for potential use in hover and steep ascend from a stationary position.
Originality/value
This research was inspired by the extremely short take-off of the V-22, when its rotors were tilted forward. It combines several design approaches in a unique way to achieve extremely short take-off capabilities combined with high-speed and reduced maintenance costs.

Abstract
Purpose
This paper seeks to identify the functional and symbolic attributes of product and brand selection that are of importance to 18‐24 consumers across food and toiletries products.
Design/methodology/approach
The investigation used both qualitative and quantitative research methods. The initial quantitative study (268 respondents) aimed to identify in order of importance (using ANOVA) the variables that drive purchase behaviour across the four product categories of soap, coffee, breakfast cereal and toothpaste.
Findings
The study identified the key importance of sensory (e.g. taste, scent) attributes in the selection of the specific products studied. These sensory attributes may define the brand positioning of the products.
Practical implications
This paper has implications for new product development.
Originality/value
Identifies the functional and symbolic attributes of product and brand selection that are of importance to 18‐24 consumers across food and toiletries products.

Abstract
Purpose
The purpose of this paper is to explain the rationale and potential for the WHO health promoting schools (HPS) to improve children ' s oral health, and describe validated quantitative methodologies and qualitative approaches to measure program impact.
Design/methodology/approach
Critical discussion of the impact of poor oral health and potential for school-based educational intervention, and evaluation methodologies used by the authors.
Findings
Using HPS to improve oral health is relevant because dental caries and gingivitis/periodontitis negatively impact children ' s health and quality of life worldwide. WHO has called for effective community-based oral health promotion programs; intervention is simple and low cost; robust evaluation measures exist – the decayed missing filled teeth index and change in cavity rate allow quantitative comparison of oral health status; and questionnaires document changes in knowledge, practices, diet, health-related quality of life, and pain.
Practical implications
Poor oral health is a major health issue. Established measures to improve oral hygiene offer an achievable, low-cost HPS entry point; the “knowledge” and “healthy practices” components central to the WHO HPS model are tried and tested and multiple potential benefits are documented. Poor oral health is a non-stigmatized issue, hence intervention is readily accepted, and effective evaluation tools provide evidence of program effect over a short (two to three years) timeframe.
Originality/value
Oral health promotion is more affordable and sustainable than the cost of traditional restorative treatments especially in middle- and low-income countries. Success with oral health leads to confidence for expansion of HPS activities to address other health issues relevant to the school community.
