Motivating students attending a teacher education programme in Hong Kong using quality learning teams

Purpose. In 1995, the Government of Hong Kong amalgamated six independent, Government sponsored Colleges of Education, which offered Certificate in Education courses, into the Hong Kong Institute of Education. The remit of the newly-formed, autonomous Institute was to attain university status and to upgrade courses to degree and post-degree level. Many of the existing staff remained with the newly-formed institute while a recruitment drive resulted in an increase in international lecturing staff. This study results from action research, undertaken by the author, to develop pedagogy suitable for both the international lecturing staff and the Chinese student teachers. The research set out to take advantage of the diverse backgrounds of the lecturing staff. Of the various pedagogic strategies employed by lecturing staff, the Total Quality Management (TQM) approach emerged as the most effective, promoting as it does a way for the students to plumb co-operatively the often difficult depths of what they are studying, as well as motivating them in their chosen career. The stringent examination system in Hong Kong, the lack of university places and the economic situation all play their part in determining the student population in the Institute of Education where students whose first choice is to enter the teaching profession could well be outnumbered by those who consider themselves without more attractive alternatives. In addition, the lecturing staff from overseas became aware of the Chinese culture of 'Shame’ among their students - the students who had failed were castigated and further marginalized by their family and friends. It was hoped that the employment of a TQM approach through the use of Quality Learning Teams would help to combat this 'shame' and, hopefully, increase the self-confidence of these 'shamed' students. The project's aim was to introduce and role-model a different pedagogic practice and to utilise constructivist-based pedagogy so that two major outcomes could be measured: (1) that student teachers would become active and confident learners who would themselves challenge their own pupils and (2) that colleagues outside the project could observe the usefulness of this alternative pedagogy and make use of the innovation in their own lecture rooms. This involved investigation of diverse aspects of teaching and learning. Research on individual areas has been quite extensive, but little research has been done in this particular area with regard to student teachers in Hong Kong and it is, therefore, the purpose of this study to add to existing knowledge, with specific emphasis on Quality Learning Teams. The rationale for the study was, on the one hand, the Hong Kong Special Administration (HKSAR) Government Educational Reforms, but also - and more importantly for the lecturers concerned - the search for a means to inculcate a culture of co-operative learning within the student-teacher body, as well as a means for international lecturing staff to create an effective pedagogy, utilizing both mother tongue and English as languages of instruction. Major Findings. The findings of the study indicated that student learning was enhanced by using Quality Learning Teams. This was demonstrated by the overall module results which showed higher module grades for the groups who were subjected to the innovative pedagogy than for those groups who were subjected to the normal 'traditional' pedagogy. Student self-esteem, self-confidence, trust in peers, and a work ethos of self-sufficiency developed amongst the majority of student teachers. Language skills were enhanced and strategies for learning were improved. It is hoped that the results of this study will assist in the future planning of courses in the education of student-teachers and in creating a more 'risk-taking' culture within the lecturing staff at the Institute

Short-term fate of rehabilitated orphan black bears released in New Hampshire

We evaluated the release of rehabilitated, orphan black bears (Ursus americanus) in northern New Hampshire. Eleven bears (9 males, 2 females; 40–45 kg) were outfitted with GPS radio-collars and released during May and June of 2011 and 2012. Bears released in 2011 had higher apparent survival and were not observed or reported in any nuisance behavior, whereas no bears released in 2012 survived, and all were involved in minor nuisance behavior. Analysis of GPS locations indicated that bears in 2011 had access to and used abundant natural forages or habitat. Conversely, abundance of soft and hard mast was lower in 2012, suggesting that nuisance behavior, and consequently survival, was inversely related to availability of natural forage. Dispersal from the release site ranged from 3.4–73 km across both years, and no bear returned to the rehabilitation facility (117 km distance). Rehabilitation appears to be a valid method for addressing certain orphan bear issues in New Hampshire

Development of the Reporting Infographics and Visual Abstracts of Comparative studies (RIVA-C) checklist and guide

People often use infographics (also called visual or graphical abstracts) as a substitute for reading the full text of an article. This is a concern because most infographics do not present sufficient information to interpret the research appropriately and guide wise health decisions. The Reporting Infographics and Visual Abstracts of Comparative studies (RIVA-C) checklist and guide aims to improve the completeness with which research findings of comparative studies are communicated and avoid research findings being misinterpreted if readers do not refer to the full text. The primary audience for the RIVA-C checklist and guide is developers of infographics that summarise comparative studies of health and medical interventions. The need for the RIVA-C checklist and guide was identified by a survey of how people use infographics. Possible checklist items were informed by a systematic review of how infographics report research. We then conducted a two-round, modified Delphi survey of 92 infographic developers/designers, researchers, health professionals and other key stakeholders. The final checklist includes 10 items. Accompanying explanation and both text and graphical examples linked to the items were developed and pilot tested over a 6-month period. The RIVA-C checklist and guide was designed to facilitate the creation of clear, transparent and sufficiently detailed infographics which summarise comparative studies of health and medical interventions. Accurate infographics can ensure research findings are communicated appropriately and not misinterpreted. By capturing the perspectives of a wide range of end users (eg, authors, informatics editors, journal editors, consumers), we are hopeful of rapid endorsement and implementation of RIVA-C.</p

Albert Pierrepoint and the cultural persona of the twentieth-century hangman

Albert Pierrepoint was Britain’s most famous 20th-century hangman. This article utilises diverse sources in order to chart his public representation, or cultural persona, as hangman from his rise to prominence in the mid-1940s to his portrayal in the biopic Pierrepoint(2005). It argues that Pierrepoint exercised agency in shaping this persona through publishing his autobiography and engagement with the media, although there were also representations that he did not influence. In particular, it explores three iterations of his cultural persona – the Professional Hangman, the Reformed Hangman and the Haunted Hangman. Each of these built on and reworked historical antecedents and also communicated wider understandings and contested meanings in relation to capital punishment. As a hangman who remained in the public eye after the death penalty in Britain was abolished, Pierrepoint was an important, authentic link to the practice of execution and a symbolic figure in debates over reintroduction. In the 21st century, he was portrayed as a victim of the ‘secondary trauma’ of the death penalty, which resonated with worldwide campaigns for abolition

LGR5 Is a Negative Regulator of Tumourigenicity, Antagonizes Wnt Signalling and Regulates Cell Adhesion in Colorectal Cancer Cell Lines

BACKGROUND: LGR5 (Leucine-rich repeat-containing G-protein coupled receptor 5) is the most established marker for intestinal stem cells. Mouse models show that LGR5+ cells are the cells of origin of intestinal cancer, and LGR5 expression is elevated in human colorectal cancers, however very little is known about LGR5 function or its contribution to the stem cell phenotype and to colorectal cancer. PRINCIPAL FINDINGS: We have modulated the expression of LGR5 by RNAi (inhibitory RNAs) or overexpression in colorectal cancer cell lines. Paradoxically, ablation of LGR5 induces increased invasion and anchorage-independent growth, and enhances tumourigenicity in xenografts experiments. Conversely, overexpression of LGR5 augments cell adhesion, reduces clonogenicity and attenuates tumourigenicity. Expression profiling revealed enhanced wnt signalling and upregulation of EMT genes upon knockdown of LGR5, with opposite changes in LGR5 overexpressing cells. These findings suggest that LGR5 is important in restricting stem cells to their niche, and that loss of LGR5 concomitant with activated wnt signalling may contribute to the invasive phenotype of colorectal carcinomas

The status of the world's land and marine mammals: diversity, threat, and knowledge

Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and marine species but suggest common mechanisms driving diversity and endemism across systems. Compared with land species, threat levels are higher among marine mammals, driven by different processes (accidental mortality and pollution, rather than habitat loss), and are spatially distinct (peaking in northern oceans, rather than in Southeast Asia). Marine mammals are also disproportionately poorly known. These data are made freely available to support further scientific developments and conservation action

Consensus guidelines for the use and interpretation of angiogenesis assays

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference
