GMA Garnets circular economy: Jebsen Jessens leadership in environmental sustainability
No full textFamily businesses are often at the forefront of sustainability efforts. In this chapter, we describe how an entrepreneurial spirit, values-based partnerships, enabling governance and purpose-driven leadership informed the sustainability agenda at the Jebsen & Jessen Family Enterprise. The company traces its roots to 1895 as one of the few non-British foreign Hongs - a cross-continental trader of supplies and chemicals. The purpose-driven leadership and determination of the Jebsen and Jessen families to build and sustain enduring partnerships and maintain their entrepreneurial drive, shifted their focus towards a green agenda, first at their Singapore operations and then in the 1990s to achieving a circular economy at their Australian garnet mining operations. GMA Garnet, a long-term business partner, was integrated into the Jebsen & Jessen Family Enterprise’s portfolio in a gradual process that lasted 25 years. The Jebsen & Jessen Family Enterprise was able to capitalize on its partnerships, entrepreneurial leadership skills and astute governance mechanisms to achieve social innovation that now serves as a role model, not only in its entire portfolio, but also globally in its industry
Dis-Orienting Rhythms: The Politics of the New Asian Dance Music
Full text linkBlurring the boundaries between academic and cultural production, this book produces a new understanding of the world significance of South Asian culture in multi-racist societies. One of the first sustained attempts to situate such production within the study of race and identity, it uncovers the crucial role that contemporary South Asian dance music has played in the formation of a new urban cultural politics. The book opens by positing new theoretical understandings of South Asian cultural representation that move beyond essentialist ethnicity in the cultural studies literature. Contributors narrate the formation of South Asian expressive culture coming emerging from the highly charged context of UK Black politics. Part three assumes the task of historical recovery, looking at the antecedents of political South Asian musical performance, autonomous anti-racist organising and problems of alliance with the white Left. Part four engages with the movements and translations of cultural productions across the world - not just in Britain or South Asia, but also Canada, North America, Fiji, Malaysia, Australia, West Africa, Europe, but particularly in the fractured spaces of a postcolonial Britain in decline
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Arsenic: An Overview of Applications, Health, and Environmental Concerns and Removal Processes
No full textArsenic is a toxic element and has been responsible for many accidental, occupational, deliberate, and therapeutic poisonings since its discovery in 1250. It occurs in natural waters as the arsenite As3+ and arsenate As5 + ions. The solubility of arsenite and arsenate compounds is relatively high so that these ions are readily transported through aqueous routes into the environment. Arsenic can be transferred from soils to crops and accumulates in various food crops and aquatic plants. The fascinating chemistry and toxicity potential make arsenic and its compounds of particular scientific interest and environmental concern. The conventional removal of heavy metals from wastewater, natural waters, and drinking water has only limited effects on arsenic removal. In this review, the main engineering and medical applications, salient health and environmental concerns, novel research on treatment for arsenic poisoning, and removal technologies for arsenic and their derivatives are discussed and enumerated with a view to pursue valuable applied research in order to protect the environment from arsenic toxicity
A scanning electron microscope characterisation of biofilm on failed craniofacial osteosynthesis miniplates
No full textINTRODUCTION: Between 3 and 18% of craniofacial osteosynthesis plates are removed due to chronic infection. Removal of the plate is necessary to manage the chronic infective state i.e. miniplate removal results in resolution of the infection. These observations are suggestive of a biofilm-related infection. The aim of this retrospective study was to characterise the presence of biofilm on the removed miniplates from oral and maxillofacial surgery.MATERIALS AND METHODS: A total of 12 plates and associated screws were recovered from eleven patients suffering from persistent, trauma site infection. The recovered plates plus 1 control plate were imaged using scanning electron microscopy (SEM). One recovered plate was also imaged using confocal microscopy (CM) for comparative purposes.RESULTS: Of the 12 plates, 3 (25%) demonstrated highly localised polymicrobial biofilms, five (42%) demonstrated coccal biofilms, one possessed a filamentous biofilm and one showed attached yeast. Overall, 75% of the plates and 82% of the patients exhibited evidence of biofilm to varying degrees. All of the infections resolved following removal of the plates and antibiotic treatment.CONCLUSION: Microbial biofilms can explain the clinical course of chronic infections associated with miniplates.</p
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
