Abstract

Purpose

Nanotechnology as an emerging area if adequately harnessed could revolutionise food packaging and food processing industry worldwide. Although several benefits of nano-materials or particles in food packaging have been suggested, potential risks and health hazards of nano-materials or particles are possible as a result of migration of their particles into food materials. The purpose of this review therefore assessed nanotechnology and its applications in food packaging, consumer acceptability of nano-packaged foods and potential hazards and safety issues in nano-packaged foods.

Design/methodology/approach

This review takes a critical assessment of previous literature on nanotechnology and its impact on food packaging, consumer health and safety.

Findings

Applications of nanotechnology in food packaging could be divided into three main divisions: improved packaging, which involves mixing nano-materials into polymers matrix to improve temperature, humidity and gas barrier resistance of the packaging materials. Active packaging deals with direct interaction between nano-materials used for packaging and the food to protect it as anti-microbial or oxygen or ultra violet scavengers. Smart packaging could be used to sense biochemical or microbial changes in foods, as well as a tracker for food safety, to prevent food counterfeit and adulteration. The review also discussed bio-based food packaging which is biodegradable. Bio-based packaging could serve as veritable alternative to conventional packaging which is non-degradable plastic polymers which are not environmental friendly and could pose a threat to the environment. However, bio-based packaging could reduce material waste, elongate shelf life and enhance food quality. However, several challenges are envisaged in the use of nano-materials in food packaging due to knowledge gaps, possible interaction with food products and possible health risks that could result from the nano-materials used for food packaging.

Originality/value

The increase in growth and utilisation of nanotechnology signifies wide use of nano-materials especially in the food sector with arrays of potential benefits in the areas of food safety and quality, micronutrients and bioactive ingredients delivery, food processing and in packaging Active studies are being carried out to develop innovative packages such as smart, intelligent and active food packaging to enhance effective and efficient packaging, as well as balanced environmental issues. This review looks at the future of nano-packaged foods vis-à-vis the roles played by stakeholders such as governments, regulatory agencies and manufacturers in looking into consumer health and safety issues related to the application of nano-materials in food packaging.

Abstract

Purpose

This study aims to explore how Farming Organisations (FOs) have utilised collective action to overcome the barriers that undermine women farmers’ participation in the agrarian economy in Malawi.

Design/methodology/approach

Key informant interviews were conducted with 17 stakeholders from across relevant governmental departments, non-governmental agencies, commercial agricultural organizations and FO officials. Focus groups discussions were conducted with women participants from five FOs.

Findings

Analysis identified barriers to women farmer’s full participation in the agricultural sector in three domains: structural (concerning land ownership and control), material (concerning access to agricultural services and markets) and socio-cultural (regarding gender roles and responsibilities). Malawian FOs demonstrated strength in addressing material barriers and in fostering re-alignment of socio-cultural conventions, but have not, to date, effectively engaged in structural issues of land reform.

Research limitations/implications

Research was conducted with a limited number of stakeholders and FOs identified through snowball sampling. There is potential for findings to be non-representative of the country as a whole, and more systematic study of FOs in Malawi is warranted to determine the generalisability of observed trends.

Practical implications

The study draws attention to the crucial importance of action regarding land reform if women are to be more effectively and equitably engaged in the agrarian economy in Malawi.

Originality/value

The paper is an examination of the experience of women farmers in Malawi and speaks to the potential contribution of FOs in addressing the challenges they face.

Abstract

Purpose

The Technology Enhanced Enterprise Education project (TE3) promotes the use of learning technologies to enhance enterprise and entrepreneurship education in the 12 HEI partners of the Mercia Institute of Enterprise (MIE). This paper describes the formal processes and procedures underpinning TE3, describes issues around material development and use, and comments on the lessons learned and added value outcomes experienced by community members.

Design/methodology/approach

TE3 works as a community of practice with regular events and online support for the sharing of materials and experience. Materials developed with TE3 funds are made available to all partners to download, adapt, and use for educational or research purposes. Community learning is captured via quarterly progress and end‐of‐project forms which ask educators to reflect on the lessons they have learned, and to note any added‐value benefits that have emerged as a result of material development.

Findings

Since its creation in August 2003, over 13,000 students have been registered to learn about enterprise using TE3 developed materials, and over 500 members of staff have been involved with TE3 through projects or training events. Educators have reported that TE3 has led to increased skills and knowledge for both themselves and their students, and increased the pool of resources available. Added‐value outcomes include increased research output, increased links with small firms, and links between academics and educators from different institutions that may not otherwise have arisen.

Practical implications

TE3 demonstrates how enterprise educators can work together to share resources and expertise, whilst embedding enterprise education within a sustainable local context, either as a dedicated module, or within a student's normal programme of study. The lessons learned by TE3 as a whole will be of use to those supporting enterprise educators, and those learned by individual TE3 projects can inform good practice in the use of e‐learning to support enterprise students.

Originality/value

TE3 has successfully supported educators and facilitated the spread of enterprise education to students in West Midlands HEIs across all subject disciplines. It is now moving into a second phase which will concentrate on dissemination of the materials produced and in supporting the community of educators that has emerged.

Abstract

Purpose

Through adoption of the psycho-emotional model of disability, this study aims to offer consumer research insight into how the marketplace internally oppresses and psycho-emotionally disables consumers living with impairment.

Design/methodology/approach

This paper draws insight from the interview data of a wider two-year interpretive research study investigating access barriers to marketplaces for consumers living with impairment.

Findings

The overarching contribution offers to consumer research insight into how the marketplace internally oppresses and psycho-emotionally disables consumers living with impairment. Further contributions offered by this paper: unearth the emotion of fear to be central to manifestations of psycho-emotional disability; reveal a broader understanding of the marketplace practices, and core perpetrators, that psycho-emotionally disable consumers living with impairment; and uncover psycho-emotional disability to extend beyond the context of impairment.

Research limitations/implications

This study adopts a UK-only perspective. However, findings uncovered that the model of psycho-emotional disability has wider theoretical value to marketing and consumer research beyond the context of impairment.

Practical implications

The insight offered into the precise marketplace practices that disable consumers living with impairment leads this paper to call for a revising of disability training within marketplace and service contexts.

Originality/value

Extending current consumer research and consumer vulnerability research on disability, the empirical adoption of the psycho-emotional model of disability is a fruitful framework for extrapolating insight into marketplace practices that internally oppress and psycho-emotionally disable consumers living with impairment.

Abstract

Purpose

Important reserves of oil and gas, which are left to be discovered and produced, are mainly concentrated in challenging locations and under severe conditions such as high pressure (HP)/high temperature (HT). The presence of aggressive environments including H2S, CO2 and chlorides plus HP/HT causes a series of corrosion problems, which cost the oil industry billions of dollars a year. Thus, there is an increasing challenge for tubes (i.e. oil country tubular goods, for short, OCTG) used in producing oil and gas. The purpose of this study is to summarize different kinds of corrosion problems and their mitigation, to more efficiently protect OCTG from corrosion.

Design/methodology/approach

To effectively select proper mitigation methods, the mechanism of corrosion must be understood, which can be classified into four categories: sweet corrosion, sour corrosion, galvanic corrosion and microbiologically induced corrosion. Also, the effects of environmental and material factors on the corrosion rate are presented. Subsequently, current technology of mitigating these corrosion problems has been discussed, including the development of materials, application of chemical inhibitors and application of protective layers.

Findings

It is stressed that limits exist for each individual mitigation method; therefore, a careful balance between economic life of OCTG and safety in operation is required.

Originality/value

The main purpose of this essay is to give a brief review and detailed introduction and analysis about those technologies.

Abstract

Within a few years it is expected that the Fire Precautions Act (1971), at present only applicable to hotels, boarding houses, shops, offices and factories, will be extended to cover all buildings‐and the onus of compliance will be placed on the building owner or ‘the responsible person’: the facilities manager? Eric Marchant, of the University of Edinburgh's Department of Fire Safety Engineering, puts this vast subject into perspective.
