Abstract

Purpose

The prevalence of foodborne illness remains high in Australia. In response, government initiatives have been implemented to inform consumers of ways to safely handle food. The aim of this study was to examine the accuracy of prompted and unprompted recall of messages from a safe food-handling media campaign in Western Australia, and whether this accuracy of prompted and unprompted recall differed by demographic factors and the mode of delivery of the campaign materials.

Design/methodology/approach

Survey responses from 121 participants (Mage = 47.15 years, SD = 15.52) who reported seeing or hearing the campaign were analysed. A series of chi-square tests were used to determine the accuracy of recall when prompted and unprompted, and the accuracy of unprompted and prompted recall across demographic factors and mode of delivery.

Findings

Results indicated that more participants accurately recalled the campaign messages when prompted (66.1%) compared to unprompted (35.5%), when they had seen outdoor advertisements (e.g. at bus stops or in shopping malls), and if they were between 30 and 45 years of age.

Originality/value

This study is the first to explore the uptake and comprehension of messages from a safe food-handling media campaign. Evaluation of safe food-handling media campaigns has shown some efficacy in relation to behaviour change; however, little is known about the uptake or comprehension of the campaign messages, and factors that may influence this.

Abstract

Outlines previous research relevant to the risks involved in residential mortgages and suggests some reasons for the gap between theory and market practice. Develops a model which adds household income, ability to pay problems and mortgage underwriting constraints to the standard pricing models, using a combination of Monte Carlo simulation and the backward finite difference method to apply it to data on house prices, income and interest rates for 62 US metropolitan areas. Discusses the results which suggest that prepayment risk dominates default risk in all except very low growth housing markets. Adds that increasing loan‐to‐value levels decrease loan values in low growth markets, slightly increase them in high growth/low volatility markets (due to decline in prepayment risk), but have little impact on high growth/high volatility markets (because they are offset by changes in default and prepayment costs). Considers the practical implications of the findings, e.g. for portfolio managers.

Abstract

Purpose

The purpose of this paper is to investigate: how dimensions of tone vary across different forms of corporate accountability narrative; the impact of tone on readability; and the determinants of tone, including consideration of its use in impression management.

Design/methodology/approach

Using a multi-year sample of listed companies, the authors measure dimensions of tone across multiple narrative types within the annual report and standalone corporate social responsibility report. Statistical analysis is used to investigate variations of tone across narrative type, each dimension’s influence on readability and the role of antecedent factors.

Findings

Analysis reveals that dimensions of tone vary significantly across narrative types (genres) suggesting that tonal patterns form part of the specific stylistic conventions of each genre. Tone is found to be a significant determinant of readability. Little evidence of obfuscation using tone was found, while disclosure type is the most salient determinant of tone.

Practical implications

The study illuminates latent or underlying disclosure norms that can facilitate the identification of “exceptional” cases that do not conform with expected tonal patterns of a particular narrative type and may warrant closer inspection by preparers, auditors or regulators. The issues raised regarding the clarity and balance of textual disclosures highlight the challenges in regulating corporate narratives.

Originality/value

This study highlights that tone is a more nuanced and layered concept than suggested by much of the prior literature. Further, tone ought to be considered in studies examining textual complexity.

Abstract

Purpose

This paper aims to investigate how different knitted structures affect the illuminative effect of polymeric optical fibres (POFs).

Design/methodology/approach

Knit prototypes were constructed using a 7-gauge industrial hand flat knitting machine. The textile prototype swatches developed in this study tested POF illumination in three types of knitting structures: intervallic knit and float stitch structures; POF inlaid into double plain and full cardigan structures; and double plain and partial knitting structures. The illuminative effects of the POFs in seven prototype swatches were analysed and compared.

Findings

It is possible to use an industrial hand flat knitting machine to knit POFs. Longer floats expose more POFs, which boosts illumination but limits the textile’s horizontal stretchability. The openness of the full cardigan structure maximises POF exposure and contributes to even illumination. The partial knitting in different sections achieves the most complete physical integration of POFs into the knitted textiles but constrains the horizontal stretchability of the textiles.

Practical implications

The integration of POFs into knitted textiles provides a functional illuminative effect. Applications include but are not limited to fashion, architecture and interior design.

Originality/value

This study is novel, as it investigates new POF knitted textiles with different loop structures. This study examines how knit stitches affect POFs in intervallic knit and float stitch, inlaid POF double knit, double plain and partial knit and the illuminative effects of the knitted textile.

Abstract

If it is a fraud to dye an unripe orange to make it look ripe, why should it be permissible to dye winter butter to make it look like summer butter?”, he says. Or one might add, to dye a biscuit brown to imply the presence of chocolate or to colour a cake yellow to simulate the addition of eggs? Our third heading is, What? What colouring matters should be allowed, and upon what conditions? Great Britain is the only leading country which has not a legal schedule of permitted colours. In this country any colouring agent may be added to food, except compounds of antimony, arsenic, cadmium, chromium, copper, mercury, lead and zinc. Gamboge, picric acid, victoria yellow, manchester yellow, aurantia and aurine are also prohibited. The addition, however, of any other colouring agent which is injurious to health would be an offence under the Food and Drugs Act. Other countries, including the United States of America, France, Canada, Australia, New Zealand, Italy, Spain, Sweden and Denmark have drawn up lists of permissible colours. And so the question arises—is it preferable to draw up a list of permissible colours or one of prohibited colours? It is obvious that if only certain colours are prohibited the remainder may be legally employed so long as they are not injurious to health. Thus a colouring agent may be used for a considerable time before it is proved to be injurious, whereas, if only‐certain colouring agents which have been previously proved to be non‐injurious were permitted, this risk of possible danger to health would be avoided. There is no doubt that in many cases proof of injury to the health of the human being is difficult to obtain. Much of the work that has been carried out to establish whether a particular dye is harmless or not has involved the use of dogs as test subjects. This does not appear to be a very satisfactory method of testing, for obviously dogs may react very differently from human beings towards chemicals. A dog's digestive powers are stronger than those of humans. No one would think of suggesting that bones are suitable food for humans just because dogs love them! Matta found that the capacity to depress the human digestion is possessed not only by poisonous dyes but also by dyes which he had proved to be non‐poisonous to animals. In bacteriology the addition of very small amounts of certain dyes to the culture medium will retard the growth of particular organisms and therefore it would seem possible that some dyes might adversely affect the action of enzymes in the body. So it would seem of importance that, if possible, all colouring matters, before being permitted to be used in food, should be proved by a competent authority to be harmless to human beings. If the effects of colouring matters upon the human digestive processes cannot be easily carried out in the body then it might be possible to perform such tests in vitro, using artificial gastric juice. It may be argued that the proportion of colouring matter added to food, ranging from about 1 part in 2,000 to about 1 part in 300,000, is so small that any particular colouring agent would need to be a deadly poison before any appreciable injurious effect upon health would occur. This argument does not, however, take into account the possible injurious effects which may be caused by the frequent ingestion of colouring matters which may have but mild toxic properties. It is known, for instance, that many synthetic colours have marked antiseptic properties even in highly diluted solutions, and therefore they may adversely affect the digestive processes. In any case, surely it would be wiser to eliminate all risks by requiring that official physiological tests should be carried out upon colouring matters before they are permitted to be used in food. One has to safeguard not only the healthy person but also the very young, the old and those who are of a delicate constitution. A harmless colour has been defined in Canada as one “which will not retard digestion nor have special physiological effects when consumed in quantities corresponding to 2 grains per day per adult.” The Departmental Committee in its report on “The use of preservatives and colouring matters in food,” published in 1924, stated that “It appears to us that definite evidence from direct experiments should be obtained as to the harmlessness of a dye before its use should be permitted in food. We have therefore come to the conclusion that a list of permitted colours should be prepared and that no colours other than those in such a list should be allowed to be used in the preparation of food. The list should, in our opinion, be prepared by the Minister of Health and issued by him, provision being made for the consideration of claims advanced by traders for the recognition and approval of additional colours on satisfactory evidence of harmlessness. We do not think that action such as this should seriously embarrass manufacturing interests, or is a course on which it is unreasonable, in view of the importance of the subject, to insist.” Yet, in spite of these recommendations of the Committee, no list of permitted colours was passed into law, and one wonders why. One argument against the drawing up of a list of prohibited colours is that even if a non‐prohibited colour is proved to the satisfaction of a given Court to be injurious to health that decision is not binding on other Courts and so there may be a lack of uniformity. A certain colour may be permitted in one town and prohibited in the next, which fact might add to the difficulties of the large scale manufacturer whose products are sold over a wide area. The leading manufacturers of dyes for use in food no doubt exercise great care in their preparation and such products are normally free from objectionable impurities, but it is possible that other dyestuff manufacturers are not so particular concerning the purity of their products. For instance, about 1938 a firm was fined for selling “Damson Blue” containing 540 parts of lead per million. Therefore it would seem necessary that some official control over the dyes that are sold for use in food should be introduced. The manufacture of some dyes involves complicated processes, and it is stated that in the production of one particular colour over 100 different chemicals are used and thirty different reactions, occupying several weeks, must be carried out before the finished colour is produced.

Abstract

Purpose – Drawing on Transformative Learning (TL) theory, the authors suggest a new and novel way to approach the study of violent radicalization.

Methodology/Approach – First, their argument is supported by the development of a Transformative Radicalization (TR) framework that borrows and adapts the core tenets of TL theory. Second, they provide a preliminary illustrative exploration of TR using two autobiographical accounts of militant radicalization (Islamist and Anarchist) from the UK and Canada.

Findings – Radicalization is a cognitive and emotional process of change that prepares and motivates an individual to pursue violent behavior. That process of change is incremental; individuals learn and adopt novel political, social, ideological, and/or religious ideals that justify and legitimize indiscriminate violence. The TR framework provides a more nuanced appreciation for the cognitive aspects involved in this process. The authors’ empirical illustrations provide guidance on how subsequent research might use original interview data on individual radicalization processes to develop more in-depth, cross-case comparisons.

Originality/Value – This theory builds a cross-disciplinary understanding of violent radicalization that highlights the way adults learn, alter their meaning perspectives, and change their behavior.

Abstract

Purpose

The purpose of this article is to develop a smart illuminated polymeric optical fibre (POF) chameleonic garment, using a wearable device technology for camouflage or safety warnings based on user needs.

Design/methodology/approach

This study integrates the theory of the optical foundation, control system, wireless communication, program development and apparel design into a chameleonic garment, displaying some vests, bags and shoes.

Findings

After selecting a pixel in the photo taken by the smart phone, the four modes of the application developed in this study are used to change the POF colour of the garment.

Originality/value

This study develops four modes of smart phone application; picked mode: picks a pixel colour on a smart phone canvas, contrastive mode: transfers to contrastive colour of the picked pixel, customized mode – gives input colour number manual and random mode – it based on a system random number. When users have different functional requirements, the four modes provide various choices.

Abstract

Purpose

It is important to monitor wrist four direction movements (flexion, extension, adduction and abduction) for hand healthcare, wrist rehabilitation and upper limb exercise, and so on. The purpose of this study is to develop a quadri-directional optical bending sensor that integrated wearable device technology in a smart glove to detect wrist four direction movements.

Design/methodology/approach

The quadri-directional optical bending sensor was designed with a microcontroller board, a Bluetooth wireless module, a side-emitting polymeric optical fibre (POF), an infrared light emitting diode and four phototransistors. A linear equation was deduced to calculate bending angle from detecting sensor value of Arduino microcontroller. The bending angle values could be seen by the smartphone screen, so the system has a good human–machine interface function.

Findings

The light emission by macro-bending of the side-emitting POFs that the transmittance of the outer side is greater than the inner. The bending POFs lateral emission phenomenon integrated with phototransistors on the edge is suitable for the development of bending sensors.

Originality/value

This study is to develop a novel quadri-directional optical bending sensor to replace two bi-direction sensors or four uni-direction sensors for wrist four direction movements monitoring.
