Review of Videotape Presented at the 6th Annual Conference on Ethnic and Minority Studies: Alan Hertzberg, The Autobiography of Miss Jane Dubois

To say that The Autobiography of Miss Jane Dubois is an exciting new departure in the venerable art of autobiography does not do full justice to the work under review here. Nor is it sufficient to say that in giving us this study of human life, producer Alan Hertzberg proves that works of integrity and high purpose can be crafted by the video artist, holding out the promise that if it would, American television could lift itself from the slough of mediocrity in which it has ever wallowed. What makes this twelve- chapter study an unforgettable experience is Jane Dubois herself, the young black woman from New York City whose life we ”watch“ unfold over the course of three hours

The development of competitive advantage through sustainable event management

Purpose: Whilst the debate rages between progressive and destructive considerations of economic development, this paper aims to develop thinking around the sustainable event and its contribution to competitive advantage. Design/methodology/approach: The paper defines the sustainable event and considers different position that might be adopted by private and public sector organisations when addressing the triple bottom line of sustainable development. Findings: Cost leadership strategies are unlikely to work and the event organiser must address competitive advantage via differentiation and focus strategies. Practical implications: Event managers must gain a better understanding of the motivations of their audience in relation to sustainability and work towards clearer means to demonstrate that their event meets these sustainable development needs. Originality/value: The intention being that if event organisers can see a competitive advantage in the sustainable event, their contribution to sustainable development will be increased. © Emerald Group Publishing Limited

An efficient one-step site-directed deletion, insertion, single and multiple-site plasmid mutagenesis protocol

Background: Mutagenesis plays an essential role in molecular biology and biochemistry. It has also been used in enzymology and protein science to generate proteins which are more tractable for biophysical techniques. The ability to quickly and specifically mutate a residue(s) in protein is important for mechanistic and functional studies. Although many site-directed mutagenesis methods have been developed, a simple, quick and multi-applicable method is still desirable. Results: We have developed a site-directed plasmid mutagenesis protocol that preserved the simple one step procedure of the QuikChange (TM) site-directed mutagenesis but enhanced its efficiency and extended its capability for multi-site mutagenesis. This modified protocol used a new primer design that promoted primer-template annealing by eliminating primer dimerization and also permitted the newly synthesized DNA to be used as the template in subsequent amplification cycles. These two factors we believe are the main reasons for the enhanced amplification efficiency and for its applications in multi-site mutagenesis. Conclusion: Our modified protocol significantly increased the efficiency of single mutation and also allowed facile large single insertions, deletions/truncations and multiple mutations in a single experiment, an option incompatible with the standard QuikChange (TM). Furthermore the new protocol required significantly less parental DNA which facilitated the DpnI digestion after the PCR amplification and enhanced the overall efficiency and reliability. Using our protocol, we generated single site, multiple single-site mutations and a combined insertion/deletion mutations. The results demonstrated that this new protocol imposed no additional reagent costs (beyond basic QuikChange T) but increased the overall success rates.Publisher PDFPeer reviewe

Student experience of gamified learning: a qualitative approach

Student engagement and student outcomes in Higher Education continue to be the subject of academic concern, and thus receive research attention. To address these concerns, we aim to explore the use of gamification to enhance student engagement, and thereby improving student learning and performance. Gamification represents the use of game elements to enhance engagement in activities such as learning.  This paper highlights the use of game elements such as: leader boards, scores for activities, and multiplayer (group) activities.  The paper does this by exploring students’ learning journeys, as well as their experience of modules in which gamification had been introduced. Group-based competitive activities were introduced to modules undertaken by business students, student nurses, and paramedic students.  Students undertaking these modules were invited to participate in semi-structured interviews.  Twelve students drawn from the three disciplines took part in these semi-structured interviews, which were digitally recorded to enable production of accurate transcripts. Thematic analysis was used to identify key themes from the interviews. To explain student responses and their learning experience, four themes were developed; challenge, difference, group processes, and competition. Students often presented themselves as enjoying challenge, although this was sometimes contrasted with enjoyment of ‘easy’ activities.  Challenge was presented not only as a motivational factor, but also sometimes as a barrier to success.  This sense of challenge was often conceptually linked to students’ perception of difference within their gamified learning, which was pedagogically distinct from their typical learning experience.  Most, but not all, expressed positive views of this difference.  As with the theme of challenge, discussion of difference could be both positive and negative.  Participants highlighted competition as a positive factor.  The competition between groups influenced some group processes.  Some students noted previous challenges involved in group-work, such as unequal work distribution.  Participants observed the potential for intra-group friction, while identifying the positive learning outcomes of group work.  Taken together, the analysis suggests that competitive group work is a beneficial strategy for enhancing student engagement and performance

Product-Related Risk and Cognitive Biases: The Shortcomings of Enterprise Liability

Products liability law has witnessed a long debate over whether manufacturers should be held strictly liable for the injuries that products cause. Recently, some have argued that psychological research on human judgment supports adopting a regime of strict enterprise liability for injuries caused by product design. These new proponents of enterprise liability argue that the current system, in which manufacturer liability for product design turns on the manufacturer\u27s negligence, allows manufacturers to induce consumers into undertaking inefficiently dangerous levels or types of consumption. In this paper we argue that the new proponents of enterprise liability have: (1) not provided any more than anecdotal evidence for their thesis; (2) failed to account for the mechanisms the law already has available to counter manufacturer manipulation of consumers; and (3) made no effort to address the well-known problems enterprise liability creates. Furthermore, even on its own terms, the new arguments for enterprise liability fail to consider the tendency of some manufacturers to exacerbate the risks that some products pose - a tendency that enterprise liability would exacerbate. In short, the insights gleaned from psychological research on human judgment do not support adopting a system of strict enterprise liability for products

Investigating the Potential of Fee-Based Recreation on Private Lands in the Lower Mississippi River Delta

Private landowners may be willing to allow public access for fee-based wildlife-associated recreation. A survey and econometric techniques are proposed to determine what characteristics may influence the probability to decide to offer recreation, what organizational form landowners may prefer to manage and market fee-based recreation, and how liability concerns and other possible disincentives collectively influence landowners' access decisions.wildlife-associated recreation, liability perceptions, Resource /Energy Economics and Policy,
