Face-to-face or distance training? Two different approaches to motivate SMEs to learn - an update
In the past, too many government-sponsored initiatives have presented learning resources that have been wasted because the target small business audience has failed to make use of them. This paper explores the issue of offering learning materials to small and medium-sized enterprises (SMEs) in a manner that recognizes their working environment, mode of operation and preferred learning methods. It then outlines methods currently being tested in the UK and Ireland, and indicates preliminary findings. The two methodologies are different in that the UK (LSSB - Learning Support for Small Businesses) programme is aimed at distance learning in primarily small businesses, whilst the Irish (University of Limerick and Limerick City Enterprise Board) programme is aimed at face-to-face learning primarily in micro-enterprises. Preliminary findings are presented

An external link to the publisherâs copy is included.OBJECTIVE: To assess if there are any differences in statin prescribing across Australia by socioeconomic status or sex and to relate prescribing rates to coronary heart disease (CHD) mortality rates. DESIGN: Cross-sectional study using data on statin prescribing by age, sex and patient postcode for the period May to December 2002. SETTING AND PARTICIPANTS: The Australian population, stratified by sex and quintile of Index of Relative Socio-Economic Disadvantage (IRSD). MAIN OUTCOME MEASURES: Age-standardised rates of statin scripts per 1000 population per month for each sex and IRSD quintile. RESULTS: 9.1 million prescriptions for statins were supplied between May and December 2002, for a total cost of $570 million. The age-standardised rates for statin prescribing in women varied from 56.9 (95% CI, 56.6â57.2) scripts per 1000 population per month in the most disadvantaged socioeconomic quintile through 53.4 (95% CI, 53.0â53.7), 50.3 (95% CI, 50.0â50.6), 48.4 (95% CI, 48.1â48.7) to 46.3 (95% CI, 46.0â46.6) in the least disadvantaged quintile. For men the figures were 52.6 (95% CI, 52.3â52.9), 50.9 (95% CI, 50.6â51.2), 48.8 (95% CI, 48.6â49.1), 47.7 (95% CI, 47.4â47.9), and 51.9 (95% CI, 51.6â52.2). There was a significant linear association between statin prescribing and CHD mortality by quintile of socioeconomic disadvantage in women (weighted least squares slope, 0.380; 95% CI, 0.366 to 0.395; P < 0.0001), but not in men (slope, â0.002; 95% CI, â0.010 to 0.006; P = 0.65). Conclusions: Our results suggest that in men there is either overprescribing of statins in the highest socioeconomic quintile or underprescribing in the lowest. Furthermore, contrary to expectation, women â relative to men â are prescribed statins at higher rates at lower levels of risk (using CHD deaths as a proxy MJA 2004; 180: 229â231 measure of risk).Nigel P Stocks, Philip Ryan, Heather McElroy and James Alla
The PAS domain-containing histidine kinase RpfS is a second sensor for the diffusible signal factor of <em>Xanthomonas campestris</em>
Summary: A cell-cell signalling system mediated by the fatty acid signal DSF controls the virulence of Xanthomonas campestris pv. campestris (Xcc) to plants. The synthesis and recognition of the DSF signal depends upon different Rpf proteins. DSF signal generation requires RpfF whereas signal perception and transduction depends upon the sensor RpfC and regulator RpfG. Detailed analyses of the regulatory roles of different Rpf proteins have suggested the occurrence of further sensors for DSF. Here we have used a mutagenesis approach coupled with high-resolution transcriptional analysis to identify XC_2579 (RpfS) as a second sensor for DSF in Xcc. RpfS is a complex sensor kinase predicted to have multiple Per/Arnt/Sim (PAS) domains, a histidine kinase domain and a C-terminal receiver (REC) domain. Isothermal calorimetry showed that DSF bound to the isolated N-terminal PAS domain with a Kd of 1.4ÎŒM. RpfS controlled expression of a sub-set of genes distinct from those controlled by RpfC to include genes involved in type IV secretion and chemotaxis. Mutation of XC_2579 was associated with a reduction in virulence of Xcc to Chinese Radish when assayed by leaf spraying but not by leaf inoculation, suggesting a role for RpfS-controlled factors in the epiphytic phase of the disease cycle.</p
Trickster Discourse in Narrative Chance: How Gerald Vizenor Helped Shape My Life in Academia
As a doctoral student in Anthropology at the University of British Columbia in the early 1990s, and just beginning research on humor in the work of contemporary Native American and Canadian First Nations artists, I chanced upon the book, Narrative Chance: Postmodern Discourse on Native American Indian Literatures, edited by Gerald Vizenor. It was a serendipitous, even fateful discovery. The final chapter in this book, written by Vizenor, explored the concept of âtrickster discourseâ. I subsequently framed my dissertation as a trickster discourse, a spirited conversation by and about a new generation of indigenous visual artists who, as âcompassionate trickstersâ (another key Vizenor concept), employed humor and irony and serious play to reimagine Native American experience in the past, present and future.  UBC Press and the University of Washington Press later published the dissertation as a book titled, The Trickster Shift: Humour and Irony in Contemporary Native Art.  Gerald Vizenor wrote a very generous endorsement for the dust jacket, and was later instrumental in the book receiving an American Book Award -- the same award that Gerald received for Griever: An American Monkey King in China. I was deeply honored. In the wake of the bookâs success, I was offered the position of New Sun Chair in Aboriginal Art and Culture at Carleton University in Ottawa, where, for the past fifteen years I have been teaching in the School of Indigenous and Canadian Studies and the Department of Art History, and where I host an annual conference on aboriginal arts. At the ninth annual conference in 2010 I had the great pleasure of presenting Gerald Vizenor, the most compassionate trickster I know. This essay, based on a presentation delivered at a conference in his honor at the University of Vienna in 2014, traces Gerald Vizenorâs impact and influence on my teaching and research over the last two decades.Â
EVALUATING ARTIFICIAL INTELLIGENCE METHODS FOR USE IN KILL CHAIN FUNCTIONS
Current naval operations require sailors to make time-critical and high-stakes decisions based on uncertain situational knowledge in dynamic operational environments. Recent tragic events have resulted in unnecessary casualties, and they represent the decision complexity involved in naval operations and specifically highlight challenges within the OODA loop (Observe, Orient, Decide, and Assess). Kill chain decisions involving the use of weapon systems are a particularly stressing category within the OODA loopâwith unexpected threats that are difficult to identify with certainty, shortened decision reaction times, and lethal consequences. An effective kill chain requires the proper setup and employment of shipboard sensors; the identification and classification of unknown contacts; the analysis of contact intentions based on kinematics and intelligence; an awareness of the environment; and decision analysis and resource selection. This project explored the use of automation and artificial intelligence (AI) to improve naval kill chain decisions. The team studied naval kill chain functions and developed specific evaluation criteria for each function for determining the efficacy of specific AI methods. The team identified and studied AI methods and applied the evaluation criteria to map specific AI methods to specific kill chain functions.Civilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCaptain, United States Marine CorpsCivilian, Department of the NavyCivilian, Department of the NavyApproved for public release.

Biochemical Validation of Patient-Reported Symptom Onset Time in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention
AbstractObjectivesThis study evaluated a biochemical validation of patient-reported symptom onset time in patients with ST-segment elevation myocardial infarction (STEMI).BackgroundSymptom onset time is an important metric but has never been formally validated.MethodsThe Mayo Clinic Percutaneous Coronary Intervention (PCI) Registry was interrogated to obtain baseline, procedural, and outcome data on 607 STEMI patients undergoing primary PCI. Biochemical onset time was determined by backward extrapolation of serial increasing cardiac troponin T (cTnT) measurements.ResultsThe median patient-reported onset time was 12 min later than the calculated time of first cTnT increase and was therefore estimated to be 4.2 h later than the biochemical onset time (interquartile range: 1.9 to 11.1 h; p < 0.001), assuming a 4-h interval between coronary occlusion and first cTnT increase. Conventional ischemic time showed no association with infarct size (correlation with peak cTnT: r = 0.023; p = 0.61) or 1-year mortality (hazard ratio: 0.97 per doubling; 95% confidence interval: 0.68 to 1.40; p = 0.88). However, after recalculation of ischemic time with biochemical onset time, significant associations with infarct size (r = 0.14; p = 0.001) and 1-year mortality (hazard ratio: 1.70 per doubling; 95% confidence interval: 1.20 to 2.40; p = 0.003) were found. When underestimation of ischemic time by patient-reported onset time increased, so did the risk of mortality.ConclusionsAlthough our point estimate should be interpreted with caution, our study indicates that the actual onset of STEMI is likely to be earlier than the patient-reported onset time. Recalculation of ischemic time with biochemical onset time greatly enhanced its prognostic value. Underestimation of ischemic time by patient-reported onset time occurred more often in high-risk patients
Coming Out to Care: Caregivers of Gay and Lesbian Seniors in Canada
Purpose:âThis article reports on the findings of a study whose purpose was to explore the experiences of caregivers of gay and lesbian seniors living in the community and to identify issues that emerged from an exploration of access to and equity in health care services for these populations.âDesign and Methods: The study used a qualitative methodology based upon principles of grounded theory in which open-ended interviews were undertaken with 17 caregivers living in three different cities across Canada.âResults:âFindings indicated several critical themes, including the impact of felt and anticipated discrimination, complex processes of coming out, the role of caregivers, self-identification as a caregiver, and support.âImplications:â We consider several recommendations for change in light of emerging themes, including expanding the definition of caregivers to be more inclusive of gay and lesbian realities, developing specialized services, and advocating to eliminate discrimination faced by these populations
A Randomized Controlled Trial to Compare Computer-assisted Motivational Intervention with Didactic Educational Counseling to Reduce Unprotected Sex in Female Adolescents
Study Objective: To examine a computer-assisted, counselor-guided motivational intervention (CAMI) aimed at reducing the risk of unprotected sexual intercourse.
Design, Setting, Participants, Interventions, and Main Outcome Measures: We conducted a 9-month, longitudinal randomized controlled trial with a multisite recruitment strategy including clinic, university, and social referrals, and compared the CAMI with didactic educational counseling in 572 female adolescents with a mean age of 17 years (SD = 2.2 years; range = 13-21 years; 59% African American) who were at risk for pregnancy and sexually transmitted diseases. The primary outcome was the acceptability of the CAMI according to self-reported rating scales. The secondary outcome was the reduction of pregnancy and sexually transmitted disease risk using a 9-month, self-report timeline follow-back calendar of unprotected sex.
Results: We conducted a 9-month, longitudinal randomized controlled trial with a multisite recruitment strategy including clinic, university, and social referrals, and compared the CAMI with didactic educational counseling in 572 female adolescents with a mean age of 17 years (SD = 2.2 years; range = 13-21 years; 59% African American) who were at risk for pregnancy and sexually transmitted diseases. The primary outcome was the acceptability of the CAMI according to self-reported rating scales. The secondary outcome was the reduction of pregnancy and sexually transmitted disease risk using a 9-month, self-report timeline follow-back calendar of unprotected sex.
Conclusion: Among those who completed the intervention, the CAMI reduced unprotected sex among an at-risk, predominantly minority sample of female adolescents. Modification of the CAMI to address methodological issues that contributed to a high drop-out rate are needed to make the intervention more acceptable and feasible for use among sexually active predominantly minority, at-risk, female adolescents
Globular Cluster Systems of Relic Galaxies
We analyse the globular cluster (GC) systems of a sample of 15 massive,
compact early-type galaxies (ETGs), 13 of which have already been identified as
good relic galaxy candidates on the basis of their compact morphologies, old
stellar populations and stellar kinematics. These relic galaxy candidates are
likely the nearby counterparts of high redshift red nugget galaxies. Using
F814W (~I) and F160W (~H) data from the WFC3 camara onboard the Hubble Space
Telescope we determine the total number, luminosity function, specific
frequency, colour and spatial distribution of the GC systems. We find lower
specific frequencies (SN<2.5 with a median of SN=1) than ETGs of comparable
mass. This is consistent with a scenario of rapid, early dissipative formation,
with relatively low levels of accretion of low-mass, high-SN satellites. The GC
half-number radii are compact, but follow the relations found in normal ETGs.
We identify an anticorrelation between the specific angular momentum (lambda_R)
of the host galaxy and the (I-H) colour distribution width of their GC systems.
Assuming that lambda_R provides a measure of the degree of dissipation in
massive ETGs, we suggest that the (I-H) colour distribution width can be used
as a proxy for the degree of complexity of the accretion histories in these
systems.Comment: MNRAS accepte
