When totems beget clans: The brand symbol as the defining marker of brand communities

The veneration of brands as part of “brand communities” reflects the expansion of consumerism in advanced capitalism. But what is it about brand communities that set them apart from other community types? It is argued that brand communities differ from other types of communities in one important respect – the community is a secondary, rather than primary, effect of brand community association. In other words, the brand as symbol precedes the emergence of the brand community, rather than the symbol being employed (in a totemic fashion) to represent a pre-existing community as in other types of community. This realization opens the way for understanding the specific dynamics that characterize brand communities, particularly in their relationship with the corporate entities that legally own brands and market the branded products, and also with wider social trends where the brand comes to possess an iconic, mythic significance. It will be argued that, contrary to the recent trend in the brand community literature to view all manner of brand-oriented group activities as examples of brand communities, there are specific features that set brand communities apart from other types of community configurations. As a consequence, some of the examples put forward by analysts as brand communities might have brand community aspects, but are in fact primarily other types of community formations, such as subcultures and hobby groups. It is suggested that brand communities be viewed as a part of a continuum, with some groups according with the ideal type of brand community more than others. This is not merely important for classification purposes, but is important analytically, as it is contended that brand communities have a unique set of dynamics that sets them aside from other types of community formations

Dreams, Hiccups and Realities: What Happens When Lecturers and Students Co-Design an Online Module?

Negotiating curriculum design with students for students involves incorporating both the students’ needs and the lecturers’ requirements into the course structure, learning activities, resources and assessment tasks. In 2012, two lecturers and a group of first year undergraduate students worked together to design an online module within an on-campus course for a second year teacher education degree. During the semester when the online module was conducted, data were gathered from the lecturers and students in the course. Findings from analyses of these data are presented in this paper in terms of: 1) the lecturers’ and students’ initial dreams and plans when the online module was co-designed; 2) the hiccups and problems encountered during the online module; 3) the realities of the successful aspects of the online module; and 4) the lessons learned for future emergent and negotiated curriculum design practices in higher education contexts

Fossil carotenoids and paleolimnology of meromictic Mahoney Lake, British Columbia, Canada

Vertical distribution of fossil carotenoids in a sediment core from meromictic Mahoney Lake was studied. Besides okenone and demethylated okenone, lutein and zeaxanthin and-carotene isomers were identified. No carotenoids typical for purple nonsulfur or green sulfur bacteria were detected. The ratio of zeaxanthin to lutein (above 1:1 in all samples) indicates a dominance of cyanobacteria over green algae in the phytoplankton assemblages of the past. Okenone, which is found exclusively in Chromatiaceae, was the dominating carotenoid in all sediment zones. The oldest sediment layers containing okenone were deposited 11 000 years ago. Between 9000 and 7000 and since 3000 years b.p., Chromatiaceae reached a considerable biomass in the lake. Vertical changes in okenone concentration were not related to changes of paleotemperatures. In contrast, okenone concentrations decreased during periods of volcanic ash input. During most of the lake history, however, mean okenone concentrations were positively correlated with sedimentation rates. This indicates that vertical changes of okenone concentration in the sediment reflect past changes of purple sulfur bacterial biomass in the lake. According to these results, the past limnology of Mahoney Lake resembled that of the present with a sulfide-containing monimolimnion and a well-developed population of okenone-bearing purple sulfur bacteria

Peripheries and praxis: the effect of rubric co-construction on student perceptions of their learning

The construction of assessment rubrics is often educator-centric as lecturers work in isolation to compose grading tools. While there is a pedagogical goal to construct instruments that align with learning outcomes and guide the assessment of students’ learning, students are often at the periphery of this process. In many higher education institutions, students are accustomed to receiving assessment feedback but they are not, typically, active participants in the feedback cycle. Increasingly, institutions are seeking evidence of greater student engagement in their tertiary learning experience. Accordingly, academics seek to innovate practice and enhance curricula by creating more opportunities for student involvement, thus creating a shared understanding of it and associated assessment tasks. Responding to a gap in rubric construction practice, this paper discusses an Office for Learning and Teaching Innovation and Development Grant research project where students moved from being rubric users to being central participants in collaborative design. Drawing on data collected from a team of rubric co-constructors from one Sydney university campus – first year students and an academic in a creative non-fiction writing subject – we set out to answer the following question: What effect does the co-construction and use of rubrics have on students’ perceptions of their learning

Transforming Assessment Feedback Design: Students’ Responses to Adaptively-Released Assessment Feedback (ARAF) Strategies

The concept of Adaptively-Released Assessment Feedback (ARAF) is relatively new and, to date, has had limited application in the university sector. This article paper looks at the applications of ARAF into the assessment of courses in three different contexts across multiple disciplines at both undergraduate and postgraduate course levels. The article paper outlines the ARAF strategies and their potential for promoting a deeper learning process by enhancing student engagement with feedback. Qualitative data from students are utilized to understand student perceptions of ARAF strategies. Students reported that ARAF increased engagement with assessment feedback and, in some cases, provoked deeper reflection and encouraged them to plan their approach to future assessment tasks. Keywords: quantitative feedback, qualitative feedback, adaptively-released assessment feedback (ARAF) strategies, assessment desig

Social capital, tourism and regional development: SPCC as a basis for innovation and sustainability

Traditional views of regional development have focused on economic factors and potential innovation in technical and resource exploitation processes. Similarly, regional tourism development is usually couched in economic terms, such as number of jobs and increasing land values. This approach usually ignores the social and community aspects of tourism development, thus an alternative view argues that the community needs to be factored into our planning and development strategies to balance the traditional economic view. It is argued in this paper that fostering innovation in regional development is much more than a process of community consultation. Rather, what needs to be factored in is SPCC - social, political and cultural capital. This works in both directions; tourism development depends on a level of social, political and cultural capital in order to be a successful regional development tool (even in economic terms) while at the same time tourism development can be undertaken in a way that contributes to SPCC in the region. The paper outlines the key concepts of social capital, political capital and cultural capital. It does so within the context of regional tourism development and the concepts of systems of innovation and sustainable development

Zampanolide, a Microtubule-Stabilizing Agent, Is Active in Resistant Cancer Cells and Inhibits Cell Migration.

Zampanolide, first discovered in a sponge extract in 1996 and later identified as a microtubule-stabilizing agent in 2009, is a covalent binding secondary metabolite with potent, low nanomolar activity in mammalian cells. Zampanolide was not susceptible to single amino acid mutations at the taxoid site of β-tubulin in human ovarian cancer 1A9 cells, despite evidence that it selectively binds to the taxoid site. As expected, it did not synergize with other taxoid site microtubule-stabilizing agents (paclitaxel, ixabepilone, discodermolide), but surprisingly also did not synergize in 1A9 cells with laulimalide/peloruside binding site agents either. Efforts to generate a zampanolide-resistant cell line were unsuccessful. Using a standard wound scratch assay in cell culture, it was an effective inhibitor of migration of human umbilical vein endothelial cells (HUVEC) and fibroblast cells (D551). These properties of covalent binding, the ability to inhibit cell growth in paclitaxel and epothilone resistant cells, and the ability to inhibit cell migration suggest that it would be of interest to investigate zampanolide in preclinical animal models to determine if it is effective in vivo at preventing tumor growth and metastasis

Photosynthetic activity and population dynamics of Amoebobacter purpureus in a meromictic saline lake

Abstract A dense population of the purple sulfur bacterium Amoebobacter purpureus in the chemocline of meromictic Mahoney Lake (British Columbia, Canada) underwent consistent changes in biomass over a two year study period. The integrated amount of bacteriochlorophyll reached maxima in August and declined markedly during early fall. Bacteriochlorophyll was only weakly correlated with the light intensity and water temperature in the chemocline. In the summer, bacterial photosynthesis was limited by sulfide availability. During this period the intracellular sulfur concentration of A. purpureus cells decreased. A minimum concentration was measured at the top of the bacterial layer in August, when specific photosynthetic rates of A. purpureus indicated that only 14% of the cells were photosynthetically active. With the exception of a time period between August and September, the specific growth rates calculated from CO2 fixation rates of A. purpureus were similar to growth rates calculated from actual biomass changes in the bacterial layer. Between August and September 86% of the A. purpureus biomass disappeared from the chemocline and were deposited on the littoral sediment of Mahoney Lake or degraded within the mixolimnion. This rise of cells to the lake surface was not mediated by an increase in the specific gas vesicle content which remained constant between April and November. The upwelling phenomenon was related to the low sulfur content of A. purpureus cells and a low resistance of surface water layers against vertical mixing by wind
