Abstract
This is the pilot study of a larger project in which fortification was evaluated in a clinical intervention trial in the Vaal Triangle of South Africa. The main purpose is to determine the suitability of stock cubes and stock powder as possible vehicles for fortification. A questionnaire was developed to determine stock cube and stock powder consumption patterns and handed out to the 802 subjects in the randomly selected sample, after testing for reliability. The results showed that 97 per cent of respondents (n=802) used stock cubes or powder daily in cooking, mainly stews, with the total consumption being 26 per cent chicken, 24 per cent beef, 15 per cent oxtail, 12 per cent mutton, 12 per cent tomato and 11 per cent vegetable. Stock cubes (79 per cent) were more popular than stock powder (21 per cent). From a consumption point of view, compared with other staple foods such as wheat flour, sugar and maize meal, stock cubes and/or stock powder are consumed on a daily basis by 97 per cent respondents and might thus be suitable vehicles for delivering micronutrients to many population groups without major changes in food production or changes in customary diets.

Abstract
Purpose
This paper aims to investigate the reason for natural gas leakage from transmission pipelines between Linyi and Shouguang in China during sealing tests, explore the failure mechanism and provide a reference for taking reasonable measures to prevent such accidents.
Design/methodology/approach
Failure analysis for the steel pipe has been addressed with different methods, such as microstructure analysis, inclusion analysis, corrosion product analysis, macro- and micro-morphology analyses and bacterially catalyzed experiments.
Findings
Several bulges were observed, especially at the bottom of the steel pipe sample, with the distribution and positioning not related to the weld. The inner surface of the steel pipe was severely corroded, and the oxide scale was flaking in many places. The greatest corrosion area was identified at the bottom of the steel pipe near the gas leakage point. Severe pitting and perforation corrosion in the pipeline were observed, and the main corrosion reaction products were Fe3O4, FeO and FeS. The grain orientation distribution near the crack (coarse grains <101> and fine grains <111> at the microcrack tip) indicates that fine grains may be beneficial in hindering crack propagation.
Originality/value
The principal mechanism for the corrosion failure is supposed to be due to the interaction of chloride ions with the sulfate-reducing microorganisms present and the stress corrosion cracking by chloride and sulfide formed by the sulfate-reducing microorganisms.

Abstract
Purpose
The purpose of this paper is to investigate the effects of cultural beliefs on governance in a business network without a legal institutional framework. Particular emphasis is placed on the cross-country remittance mail operating network in Chaoshan, China, during the period 1860-1949. This investigation builds on Greif’s business governance theory and develops an analytical framework that considers cultural beliefs, agency relationships and multilateral punishment mechanisms. Furthermore, it uses the institutional analysis method to identify the institutional factors that sustained the remittance mail operating networks and their underlying mechanisms.
Design/methodology/approach
This paper adopts the qualitative research method. First, it investigates the history of the remittance mail operating network and agency relationships by searching through the contents of the relevant historical documents preserved in the official archives and information found in other records. Thereafter, it summarizes and demonstrates the cultural beliefs inferred from that research. The archival materials permit analysis of the interactions between cultural beliefs, agency relationships and multilateral punishment mechanisms by the institutional analysis method.
Findings
Due to the lack of legal institutions in China during the period under review, cultural beliefs played a central institutional role in cross-country business relations. Network governance was coupled with clan cultural beliefs in the remittance mail operating network. This relationship was the key to sustain the efficient operation of the remittance mail network.
Originality/value
In the West, corporate governance has been influenced by and has become an integral feature of Western culture and values. This is not necessarily so for the corporate governance in terms of Chinese culture and values. Thus, instead of mimicking the modes of developed countries, it is important for Chinese enterprises to seek a mode of corporate governance that is in accord with their local cultures. This may be an important focus for enterprise development.

Abstract
Purpose
The purpose of this paper is to study the evolution of Chinese industrial relations after the market reform of 1978, while basing its arguments and conclusion on analysis of the interactions of key actors in the labour arena in China. The significant phenomena in the evolution of industrial relations are the coming of transnational capital and the emergence of self‐organising protests by migrant workers.
Design/methodology/approach
The paper uses a case study approach.
Findings
The Labour Contract Law and the local political economy experience strong effects from TNCs and other business players. Meanwhile, globalisation has introduced the civil society movement to China, which has given rise to an increasing number of NGOs working for labour rights. Tight financial and technical connections between grassroots NGOs and international donor organisations make it possible for bottom‐up labour activities to counteract the unilateral influence of the state and market over the Chinese workforce. Since the ACFTU, the official trade union umbrella, has many institutional constraints to undertake a thorough transition towards labour in the near future, workers' representation is diversified.
Originality/value
One implication for further theoretical studies is that tripartism cannot fully disclose the reality of Chinese labour, and that labour representation derives from both unions and self‐organisation of workers, such as NGOs, which opens more room for the entrenchment of the grassroots labour movement to sustain the balance of power among the state, ACFTU, firms, international market forces and individual workers in the long term.

Abstract
Purpose
Food additives are a group of substances added deliberately to foods to improve their organoleptic properties and stability, extend their shelf life and retain their nutritional value. The purpose of this paper is to identify the most frequently used classes of food additives and the food categories which contain the highest number of classes of additives.
Design/methodology/approach
A market survey was carried out in hypermarkets and shops where the original labels of 629 food products (195 local and 434 imported) were examined for presence of food additives. Principal component analysis (PCA) was used to explore the association between food category and classes of additives, and a χ2 test was performed to establish any association between product origin and the number of classes of food additives.
Findings
In sum, 75 per cent of food samples surveyed contained at least one class of food additive. The food categories which contained the highest number of classes of food additives across the group were: snacks (12 classes), biscuits and cakes (11 classes), fish products (11 classes) and soft drinks (10 classes). The most common classes of additive used were acidity regulator, colour and preservative. χ2 test revealed a significant association (χ2 = 8.28, p < 0.05) between the origin and number of classes of food additives, and the PCA showed that biscuits were associated with raising agent, candies and snacks with colour, fruit drinks and soft drinks with acidity regulator, mayonnaise with thickener and meat products with preservative.
Research limitations/implications
The food products were sourced only from retailers selling labelled food products.
Originality/value
This novel study provides a basis for determining compliance of food products to the National Food Regulations.
