Feeding Ourselves Thirsty: How the Food Sector is Managing Global Water Risks

The global food sector faces extraordinary risks from the twin challenges of water scarcity and water pollution. Growing competition for water, combined with weak regulations, failing infrastructure, pollution and climate change impacts threaten the sector's water security and contribute to a water availability emergency that was recently ranked the world's "top global risk" by the World Economic Forum.This report examines how water risks affect the profitability and competitive positioning of 37 major food sector companies in four industries: packaged food, beverage, meat and agricultural products. It evaluates and ranks these companies -- the majority of which are U.S. domiciled and publicly-traded -- on how well they are positioned to anticipate and mitigate these risks, as well as contribute to improved water resource management.The report provides recommendations for how analysts and investors can effectively evaluate food sector companies on their water risk exposure and management practices. It also provides recommendations for how food companies can improve water efficiency and water quality across their operations and supply chains to reduce risks and protect water resources

The impact of cognitive styles on perceptual distributed multimedia quality

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2003 John Wiley & Sons, Inc.Multimedia technology has been widely used in web-based instruction, but previous studies have indicated that individual differences, especially cognitive styles, have significant effects on users’ preferences with respect to presentation of multimedia content. However, such research has thus far neglected to examine the effect of cognitive styles on users’ subjective perceptions of multimedia quality. This study aims to examine the relationships among users’ cognitive styles, the multimedia Quality of Service (QoS) delivered by the underlying network, and Quality of Perception (QoP), which encompasses user levels of enjoyment and understanding of the informational content provided by multimedia material. Accordingly, 132 users took part in an experiment in which they were shown multimedia video clips presented with different values of two QoS parameters (frame rate and colour depth). Results show that, whilst the two QoS parameters do not impact user QoP, multimedia content and dynamism levels significantly influence the user understanding and enjoyment component of QoP

Medium for empowerment or a 'centre for everything': students’ experience of control in digital environments within a university context

In maximising opportunities to nurture rich and productive learning communities, there is a need to know more about the cultures and sub-cultures that surround virtual learning environments (VLEs). Drawing from a small-scale interview study of students’ digital practices, this paper explores how different discourses may have patterned a group of students’ experiences of VLEs. Unlike studies which have focused upon evaluations of specific projects or interventions, this study investigated their experience across their course. It explores the student identities they associated with digital environments and the power relationships which seemed to pattern how they positioned themselves (or felt positioned) as learners. Whilst none were intimidated by technical aspects, the student identities available to them seemed to vary, as did their perceptions of the student identities associated with university-sponsored digital environments. The analysis considers three aspects of their experience: how they related to the VLE itself, how they related to others through this, and the alternative communities they created to attempt to manage their engagement with the VLE. The paper concludes by arguing for further research which focuses on the broader student experience across courses in order to explore how university-based digital environments intersect with students’ identities as learners

Review on learning orientations

The need has arises towards the consideration of individual difference to let learners engage in and responsible for their own learning, retain information longer, apply the knowledge more effectively, have positive attitudes towards the subject, have more interest in learning materials, score higher and have high intrinsic motivation level. As regard to the importance of individual differences, Martinez (2000) has grounded a new theory, which is Intentional Learning Theory that covered individual aspects of cognitive, intention, social and emotion. This theory hypothesizes that the fundamental of understanding how individual learns, interact with an environment, performs, engages in learning, experiences learning, and assimilate and accommodate the new knowledge is by understanding individual’s fundamental emotions and intentions about how to use learning, why it is important, when the suitable time, and how it can accomplish personal goals and change. The intent of this theory is to focus on emotions and intentions of an individual regarding why, when and how learning goals are organized, processed, and achieved. In conclusion, Learning Orientations introduced by this theory describes the disposition of an individual in approaching, managing and achieving their learning intentionally and differently from others

Fostering Open Educational practices in cross-cultural contexts

The open content movement is breaking down traditional barriers to learning and resource sharing by promoting free access to Open Educational Resources (OERs) such as digital educational content and technological tools for teaching and learning. OERs have the potential to enable learners to champion their own learning by providing free access to educational content and tools that enable them to create, use and share knowledge. However, the design and uptake of OERs is often hampered by limited understanding of issues relating to the context in which learners access and use OERs. This paper discusses some of the approaches taken to foster open educational practices in learner use of OERs offered by The Open University’s open content initiative, OpenLearn. Drawing on these experiences, we then consider future ideas about supporting open educational practices in cross-cultural contexts, and, in collaboration with Tshwane University of Technology, examine potential impact of OERs in Africa

From physical marketing to web marketing

Reviews the criticism of the 4P marketing mix framework as the basis of traditional and virtual marketing planning. Argues that the customary marketing management approach, based on the popular marketing mix 4Ps paradigm, is inadequate in the case of virtual marketing. Identifies two main limitations of the marketing mix when applied in online environments namely the role of the Ps in a virtual commercial setting and the lack of any strategic elements in the model. Identifies the critical factors of the Web marketing and argues that the basis for successful e-commerce is the full integration of virtual activities into the company's physical strategy, marketing plan and organisational processes. The 4S elements of the Web marketing mix framework offer the basis for developing and commercialising business to consumer online projects. The model was originally developed for educational purposes and has been tested and refined by means of three case studies

Alcohol and other drugs in the Australian construction industry: a pathway for safety focused cultural change

Background: Anecdotal evidence from the infrastructure and building sectors highlights issues of alcohol and other drugs (AODs) and its association with safety risk on construction sites. Currently, there is no clear evidence on the prevalence and risk of AOD use among Australian construction workers and there is limited evidential guidance regarding how to effectively address such an issue. Aims: The current research aims to scientifically evaluate the use of AODs within the Australian construction industry in order to reduce the potential resulting safety and performance impacts and engender a cultural change in the workforce. A nationally consistent and collaborative approach across the workforce will be adopted. Methods: A national assessment of the use of AODs was conducted in participating organisations across three states. The World Health Organisation’s Alcohol Use Disorders Identification Test (AUDIT) was used to measure alcohol use. Illicit drug use, ‘readiness to change’, impediments to reducing impairment, feasibility of proposed interventions, and employee attitudes and knowledge regarding AOD was also measured through a combination of survey items and interviews. Through an educative approach and consultation with employers, employees, union groups and leaders in applied AOD research, this assessment was used to inform and support cultural change management of AOD use in the industry. Results: Results (n=494) indicate that as in the general population, a proportion of those sampled in the construction sector may be at risk of hazardous alcohol consumption. A total of 286 respondents (58%) scored above the cut-off cumulative score for risky or hazardous alcohol use. Other drug use was also identified as a major issue. Interview responses and input from all project partners is presented within a guiding principle framework for cultural change. Conclusions: Results support the need for evidence-based, comprehensive and tailored responses in the workplace. This paper will discuss the final results in the context of facilitating cultural change in the construction industry
