This article seeks to address aviation as an emerging biofuel consumer and to discuss sustainability issues and consequences for feedstock production concepts. Biojet fuels have been identified as a promising, readily deployable alternative to fossil‐based aviation fuels. At the same time they are highly criticised as their production may have negative social and environmental impacts. Therefore, the paper aims to identify major sustainability issues and assessment challenges and relate these to the production of biojet fuel feedstock.

Two plant oil production concepts are presented that address the sustainability issues discussed. Both concepts are being investigated within the research project “Platform for Sustainable Aviation Fuels”. A literature‐based overview of sustainability issues and assessment challenges is provided. Additionally, conceptual insights into new plant oil production concepts are presented.

The use of biojet fuels is often hailed as a strategy for the aviation industry to become more sustainable. However, biofuels are not necessarily sustainable and their potential to reduce GHG emissions is highly debated. Several unresolved sustainability issues are identified highlighting the need for improved assessment methods. Moreover, the two concepts presented have the potential to provide sustainably grown feedstock, but further empirical research is needed.

This article addresses researchers and practitioners by providing an overview of sustainability issues and assessment challenges related to biojet fuels. Consequences are identified for two plant oil feedstock concepts: catch cropping in temperate regions and silvopastoral systems in tropical and subtropical regions.

Purpose: This chapter proposes narrative allyship across ability as a practice in which nondisabled researchers work with disabled nonresearchers to co-construct a process that centers and acts on the knowledge contained in and expressed by the lived experience of the disabled nonresearchers. This chapter situates narrative allyship across ability in the landscape of other participatory research practices, with a particular focus on oral history as a social justice praxis.

Approach: In order to explore the potential of this practice, the author outlines and reflects on both the methodology of her oral history graduate thesis work, a narrative project with self-advocates with Down syndrome, and includes and analyzes reflections about narrative allyship from a self-advocate with Down syndrome.

Findings: The author proposes three guiding principles for research as narrative allyship across ability, namely that such research further the interests of narrators as the narrators define them, optimize the autonomy of narrators, and tell stories with, instead of about, narrators.

Implications: This chapter suggests the promise of research praxis as a form of allyship: redressing inequality by addressing power, acknowledging expertise in subjugated knowledges, and connecting research practices to desires for social change or political outcomes. The author models methods by which others might include in their research narrative work across ability and demonstrates the particular value of knowledge produced when researchers attend to the lived expertise of those with disabilities. The practice of narrative allyship across ability has the potential to bring a wide range of experiences and modes of expression into the domains of research, history, policy, and culture that would otherwise exclude them.

Dr. COLLINRIDGE, the Medical Officer of Health to the City of London, had occasion recently to call attention to the diseased condition of certain imported meats, and it is most disquieting to learn that some of these were apparently sent out from the country of origin under official certificates.

Notwithstanding the emergence of hospitality education around the world, the hospitality industry itself has struggled to establish a talent pipeline of young ambitious managers. Typically, only 30% of hospitality students are predicted to develop their careers within the hospitality industry, while the remainder will relocate to other industries such as retail, banking and consulting. Although this manifestation has been globally documented, most studies have simply adopted a quantitative approach in defining this phenomenon; hence, despite its scale being appreciated, less attention has been paid to defining the underlying causes which drive this concern. This study contributes to this issue by interviewing 18 students at three key stages of their practical placements, namely, pre-, during and post their placement, drawing on the ‘Principles of a Sustainable HRM ROC framework’. This chapter concludes with significant findings from which some recommendations have been formulated.

The total number of samples analysed in 1911 was 103,221, an increase of 2,472 samples over the number for the previous year. The principal increases were the following: Milk, 2,954; flour, 405; bread, 291; and spirits, 255. The principal decreases occurred in lard, 973; cheese, 285; and margarine, 208.

Competitiveness has forced companies to improve the overall performance of the business. In the area of maintenance, much has been written about strategies, such as total productive maintenance or reliability centred maintenance, in order to increase the reliability and therefore capacity of the industrial plants in their quest for world‐class maintenance. However, if a strategy is to be effective, it must be supported with an invaluable resource, information. In the present work, the role of computerised maintenance management systems (CMMSs) is discussed as a powerful tool necessary for obtaining information from raw data and support the decision‐making process. Furthermore, a CMMS has been designed, developed, customised and implemented for a disc brake pad manufacturing company based in England. In addition, a maintenance maturity grid has been proposed to support the CMMS implementation. The grid shows that the complexity of the CMMS will increase as the maintenance function moves from a reactive to a proactive culture. The implemented CMMS aims to reduce total downtime and frequency of failures of the machines by improving the efficiency and effectiveness of the maintenance force. The computer program simplifies and reduces the time of data capture compared to the currently used paper‐based reporting system. It also provides the maintenance planners with a platform for decision analysis and support often ignored in the commercial CMMSs available in the market.
