Library and information science education 2.0 : guiding principles and models of best practice : interview with John Terrell

In 2005, Stephen Abram, vice president of Innovation at SirsiDynix, challenged library and information science (LIS) professionals to start becoming “librarian 2.0.” In the last few years, discussion and debate about the “core competencies” needed by librarian 2.0 have appeared in the “biblioblogosphere” (blogs written by LIS professionals). However, beyond these informal blog discussions few systematic and empirically based studies have taken place. A project funded by the Australian Learning and Teaching Council fills this gap. The project identifies the key skills, knowledge, and attributes required by “librarian 2.0.” Eighty-one members of the Australian LIS profession participated in a series of focus groups. Eight themes emerged as being critical to “librarian 2.0”: technology, communication, teamwork, user focus, business savvy, evidence based practice, learning and education, and personal traits. Guided by these findings interviews with 36 LIS educators explored the current approaches used within contemporary LIS education to prepare graduates to become “librarian 2.0”. This video presents an example of ‘great practice’ in current LIS education as it strives to foster web 2.0 professionals.

To act or not to act : this is John's dilemma

The case proposes an ethical dilemma that a Public Service Director faces that could affect his career, the career of his boss, and the career of the governor of a state. There is a strong need for ethical leaders in this changing global organization world where the headlines are filled with stories of private sector and public sector leaders who have made serious ethical and moral compromises. It is easy to follow ethical leaders who you can count on to do what is right and difficult to follow those who will do what is expedient or personally beneficial. However, ethical leadership is not always black and white as this case will portray. Difficult decisions must be made where it may not always be clear what to do. The names in the case have been changed although the situation is a real one.

Queensland Business Women Stories

These projects build on the research of Klaebe and Burgess into digital story-telling, specifically variable workshop scenarios, co-creative media, participatory public history, and the development of co-creative production processes for cultural institutions. The projects represented a partnership between QUT and the State Library of Queensland. The Five Senses project focused on the distributed digital storytelling workshop model and the development of audiences for digital storytelling. The team worked with regional artists whose work had been selected for inclusion in the Five Senses exhibition at the State Library of Queensland to produce stories about their work; these works were then integrated into the physical exhibition space. The Queensland Businesswomen project produced four digital stories profiling the lives of leading Queensland businesswomen. The digital story telling workshop model was disbanded and research teams worked individually with participants to create the digital stories. Academic research and oral history interviews were conducted initially to foreground these productions. This pilot led to a larger project, Business Leaders Hall of Fame, which now has a dedicated viewing room in the SLQ sponsored by an annual silver service dinner event. With the Responses to the Apology project, which stimulated similar projects in Mt Isa and Cairns, the research team worked with Indigenous facilitators, and the participants created their digital stories with assistance from these facilitators and the QUT research team using a mix of workshop and individual meetings. The research component of the work relates to the further development of co-creative production processes for cultural institutions, involving a wide range of institutional and individual partners, while authentically representing the intensely personal perspectives of each of the primary participants. The Queensland Business Leaders Hall of Fame was a research project that included interviews with eminent Queenslanders that produced oral history interviews and digital stories about the achievements of both Queensland personalities and businesses. This model was able to test and evaluate the use of oral history and digital storytelling for learning and community heritage purposes. Interviewees include; Sir John and Valmai Pidgeon, Joseph Saragossi, Robert Bryan, Clem Jones, Jim Kennedy, Sr Angela Mary, Castelmaine Perkins, Burns and Philp, Qantas, Don Argus & Steve Irwin All digital stories, oral history interviews and transcripts were accessioned into the library collection – an international first for digital stories. Two publications in refereed journals have resulted, and the digital stories are stored in the SLQ permanent collection for the benefit of national and international scholars and the general public.

Raman spectroscopy of synthetic CaHPO4•2H2O– and in comparison with the cave mineral brushite

The mineral brushite has been synthesised by mixing calcium ions and hydrogen phosphate anions to mimic the reactions in a Cave. The vibrational spectra of the synthesised brushite were compared with that of the natural Cave mineral. Bands attributable to the PO43- and HPO42- anions are observed. Brushite, both synthetic and natural, is characterised by an intense sharp band at 985 cm-1 with a shoulder at 1000 cm-1. Characteristic bending modes are observed in the 300 to 600 cm-1 region. The spectra of the synthesised brushite matches very well the spectrum of brushite from the Moorba Cave, Western Australia.

Get Into Vocational Education (GIVE) Rockhampton Region Pilot Project : Final Report to The John Villiers Trust

This report describes the Get Into Vocational Education (GIVE) pilot project run in the Rockhampton Region at two schools in 2011. The report includes a description of the project, including its aims, budget, and timeline; and the findings in relation to each of the three major objectives of the project, namely (a) build awareness of, interest in, and familiarity with, trades as a future vocation and opportunity for advancement; (b) enhance literacy, numeracy and science knowledge and performance; and (c) provide motivation and engagement to stay on at school and build towards a productive future. The clear findings of the GIVE Rockhampton Region pilot project are that, for students at risk in terms of school attendance, engagement and learning: (1) awareness of trade practices in horticulture, hospitality, retail, and design and engineering, literacy, mathematics and science knowledge, and motivation and engagement all improve and, in most cases, dramatically improve, in the GIVE structure; and (2) the crucial factor in the GIVE structure that gives the improvement is the integration of classroom work with trades experiences and not the classroom and trades experiences themselves (although it is better if these are good).

Shortening cemented femoral implants. An in vitro investigation to quantify exeter femoral implant rotational stability vs simulated implant length

The Exeter stems vary in length from 90 to 150 mm. The shorter stems generally have lower offsets. The purpose of this study was to determine if length of stem, with fixed offset, affected rotational stability. Mechanical testing was carried out on 10 implant-cement constructs with 2 loading profiles, rising from chair and stair climbing, at different simulated implant lengths using purpose-built apparatus. This paper presents a mechanism for clinically observed rotational stability and explains the mechanical characteristics required for rotational stability in Exeter femoral stems. © 2012.

Vertical Inhibition of the PI3K/Akt/mTOR Pathway for the Treatment of Osteoarthritis

Osteoarthritis is characterized by degenerative alterations of articular cartilage including both the degradation of extracellular matrix and the death of chondrocytes. The PI3K/Akt pathway has been demonstrated to involve in both processes. Inhibition of its downstream target NF-kB reduces the degradation of extracellular matrix via decreased production of matrix metalloproteinases while inhibition of mTOR increased autophagy to reduce chondrocyte death. However, mTOR feedback inhibits the activity of the PI3K/Akt pathway and inhibition of mTOR could result in increased activity of the PI3K/Akt/NF-kB pathway. We proposed that the use of dual inhibitors of PI3K and mTOR could be a promising approach to more efficiently inhibit the PI3K/Akt pathway than rapamycin or PI3K inhibitor alone and produce better treatment outcome.

Implantation of osteogenic differentiated donor mesenchymal stem cells causes recruitment of host cells

The interaction between host and donor cells is believed to play an important role in osteogenesis. However, it is still unclear how donor osteogenic cells behave and interact with host cells in vivo. The purpose of this study was to track the interactions between transplanted osteogenic cells and host cells during osteogenesis. In vitro migration assay was carried out to investigate the ability of osteogenic differentiated humanmesenchymal stemcells (O-hMSCs) to recruit MSCs. At the in vivo level, O-hMSCs were implanted subcutaneously or into skull defects in severe combined immunodeficient (SCID) mice. New bone formation was observed bymicro-CT and histological procedures. In situ hybridization (ISH) against human Alu sequences was performed to distinguish donor osteogenic cells from host cells. In vitro migration assay revealed an increased migration potential of MSCs by co-culturing with O-hMSCs. In agreement with the results of in vitro studies, ISH against human Alu sequences showed that host mouse MSCs migrated in large numbers into the transplantation site in response to O-hMSCs. Interestingly, host cells recruited by O-hMSCs were the major cell populations in newly formed bone tissues, indicating that O-hMSCs can trigger and initiate osteogenesis when transplanted in orthotopic sites. The observations fromthis study demonstrated that in vitro induced O-hMSCs were able to attract hostMSCs in vivo andwere involved inosteogenesis togetherwith host cells,whichmay be of importance for bone tissue-engineering applications.

Exeter short stems compared with standard length Exeter stems : experience from the Australian Orthopaedic Association National Joint Replacement Registry

The standard Exeter stem has a length of 150mm with offsets 37.5mm to 56mm. Shorter stems of lengths 95mm, 115mm and 125mm with offsets 35.5mm or less are available for patients with smaller femurs. Concern has been raised regarding the behaviour of the smaller implants. This paper analysed data from the Australian Orthopaedic Association National Joint Replacement Registry comparing survivorship of stems of offset 35.5mm or less with the standard stems of 37.5mm offset or greater. At seven years there was no significant difference in the Cumulative Percent Revision Rate in the short stems (3.4%, 95% CI 2.4-4.8%) compared with the standard length stems (3.5%, 95% CI 3.3-3.8%) despite its use in a greater proportion of potentially more difficult developmental dysplasia of the hip cases.

Cytokine responses to carbohydrate ingestion during recovery from exercise-induced muscle injury.

We investigated the effect of carbohydrate ingestion after maximal lengthening contractions of the knee extensors on circulating concentrations of myocellular proteins and cytokines, and cytokine mRNA expression in muscle. Using a cross-over design, 10 healthy males completed 5 sets of 10 lengthening (eccentric) contractions (unilateral leg press) at 120% 1 repetition-maximum. Subjects were randomized to consume a carbohydrate drink (15% weight per volume; 3 g/kg BM) for 3 h after exercise using one leg, or a placebo drink after exercise using the contralateral leg on another day. Blood samples (10 mL) were collected before exercise and after 0, 30, 60, 90, 120, 150, and 180 min of recovery. Muscle biopsies (vastus lateralis) were collected before exercise and after 3 h of recovery. Following carbohydrate ingestion, serum concentrations of glucose (30-90 min and at 150 min) and insulin (30-180 min) increased (P < 0.05) above pre-exercise values. Serum myoglobin concentration increased (similar to 250%; P < 0.05) after both trials. In contrast, serum cytokine concentrations were unchanged throughout recovery in both trials. Muscle mRNA expression for IL-8 (6.4-fold), MCP-1 (4.7-fold), and IL-6 (7.3-fold) increased substantially after carbohydrate ingestion. TNF-alpha mRNA expression did not change after either trial. Carbohydrate ingestion during early recovery from exercise-induced muscle injury may promote proinflammatory reactions within skeletal muscle.
