Organisational challenges in understanding and implementing effective buiness continuity management strategies in a complex and critical organisation : an airport case study

With the increasing complexity of modern day threats and the growing sophistication of interlinked and interdependent operating environments, Business Continuity Management (BCM) has emerged as a new discipline, offering a strategic approach to safeguarding organisational functions. Of significant interest is the application of BCM frameworks and strategies within critical infrastructure, and in particular the aviation industry. Given the increased focus on security and safety for critical infrastructures, research into the adoption of BCM principles within an airport environment provides valuable management outcomes and research into a previously neglected area of inquisition. This research has used a single case study methodology to identify possible impediments to BCM adoption and implementation by the Brisbane Airport Corporation (BAC). It has identified a number of misalignments between the required breadth of focus for a BCM program, identified differing views on specific roles and responsibilities required during a major disruptive event and illustrated the complexities of the Brisbane Airport which impede the understanding and implementation of effective Business Continuity Management Strategies.

Tow Takes on the Critical

This important volume on the critical pedagogical approach addresses such topics as critical multiculturalism, gender and language learning, and popular culture. Critical pedagogies are instructional approaches aimed at transforming existing social relations in the interest of greater equity in schools and communities. This paperback edition on the pedagogical approach addresses such topics as critical multiculturalism, gender and language learning, and popular culture. Committed to language education that contributes to social justice - and the political, economic, and sociocultural changes such justice requires - the contributors explore the meaning of creating equitable and critical instructional practices, by exploring diverse representations of knowledge. In addition, recommendations are made for further research, teacher education, and critical testing. Graduate students and researchers in TESOL, applied linguistics, and education will find this volume a thought-provoking and comprehensive presentation of theory and practice in this important new area of scholarship.

Changes in Level of Virus Accumulation and Incidence of Infection are Critical in the Characterization of Rice Tungro Bacilliform Virus (RTBV) Resistance in Rice

Analysis by enzyme-linked immunosorbent assay showed that Rice tungro bacilliform virus (RTBV) accumulated in a cyclic pattern from early to late stages of infection in tungro-susceptible variety, Taichung Native 1 (TN1), and resistant variety, Balimau Putih, singly infected with RTBV or co-infected with RTBV+Rice tungro spherical virus (RTSV). These changes in virus accumulation resulted in differences in RTBV levels and incidence of infection. The virus levels were expressed relative to those of the susceptible variety and the incidence of infection was assessed at different weeks after inoculation. At a particular time point, RTBV levels in TN1 or Balimau Putih singly infected with RTBV were not significantly different from the virus level in plants co-infected with RTBV+RTSV. The relative RTBV levels in Balimau Putih either singly infected with RTBV or co-infected with RTBV+RTSV were significantly lower than those in TN1. The incidence of RTBV infection varied at different times in Balimau Putih but not in TN1, and to determine the actual infection, the number of plants that became infected at least once anytime during the 4wk observation period was considered. Considering the changes in RTBV accumulation, new parameters for analyzing RTBV resistance were established. Based on these parameters, Balimau Putih was characterized having resistance to virus accumulation although the actual incidence of infection was >75%.

Who's at risk: Answerability and the critical possibilities of classroom discourse

Our aim in this article is twofold. First, we challenge the essentialized notion of adolescents and young people as perpetually driven to resist the authority of adults. At the same time, we disrupt linguistic conceptions of adolescent discourse, along with the discourse of youth at risk, by analyzing a transcript of classroom discourse that reflects an exchange between a highly regarded and well liked preservice teacher and his students. This representative transcript highlights the preservice teacher's ability to query, without a concomitant ability to listen, respond, and build a classroom dialogue with his students; what we call here a Socratic monologue. Second, we link the notions of dialogue and responsiveness to Bakhtin's concept of answerability, emphasizing the joint construction of classroom discourse as an ethically answerable relation between teacher and students.

Bioreactor Systems for Tissue Engineering

The hydrodynamic environment “created” by bioreactors for the culture of a tissue engineered construct (TEC) is known to influence cell migration, proliferation and extra cellular matrix production. However, tissue engineers have looked at bioreactors as black boxes within which TECs are cultured mainly by trial and error, as the complex relationship between the hydrodynamic environment and tissue properties remains elusive, yet is critical to the production of clinically useful tissues. It is well known in the chemical and biotechnology field that a more detailed description of fluid mechanics and nutrient transport within process equipment can be achieved via the use of computational fluid dynamics (CFD) technology. Hence, the coupling of experimental methods and computational simulations forms a synergistic relationship that can potentially yield greater and yet, more cohesive data sets for bioreactor studies. This review aims at discussing the rationale of using CFD in bioreactor studies related to tissue engineering, as fluid flow processes and phenomena have direct implications on cellular response such as migration and/or proliferation. We conclude that CFD should be seen by tissue engineers as an invaluable tool allowing us to analyze and visualize the impact of fluidic forces and stresses on cells and TECs.
