Measurement of the b-jet cross-section with associated vector boson production with the ATLAS experiment at the LHC
A measurement of the cross-section for vector boson production in association
with jets containing b-hadrons is presented using 35 pb-1 of data from the LHC
collected by the ATLAS experiment in 2010. Such processes are not only
important tests of pQCD but also large, irreducible backgrounds to searches
such as a low mass Higgs boson decaying to pairs of b-quarks when the Higgs is
produced in association with a vector boson. Theoretical predictions of the V+b
production rate have large uncertainties and previous measurements have
reported discrepancies. Cross-sections measured using in the electron and muon
channels will be shown. Comparisons will be made to recent theoretical
predictions at the next-to-leading order in alpha_s.Comment: Presented at the 2011 Hadron Collider Physics symposium (HCP-2011),

Session 3-1-D: Safeguarding Internet Gambling
Summary
Before placing limits, Limiters were more active bettors than others
–Played more types of games, higher frequency of betting days, placed more bets per day BUT wagered less per bet
Multi-dimensional view of gambling involvement
–Frequency of betting vs. expenditure
Self-limitation mainly reduced time spent gambling
–Wagered less over time, but driven by fewer bet
Different extraction efficiencies observed from synthetic cannabinoid analysis due to burning and matrix effects
Cannabinoids are compounds that are naturally present in Cannabis sativa L., which interact with cannabinoid receptors in the nervous system, known as CB1 and CB2 receptors. The most abundant and well-known cannabinoid that can be isolated from cannabis is 9-tetrahydrocannabinol (THC). The structure of this compound specifically allows interaction with the CB1 and CB2 receptors, known as cannabimimetic activity. Other compounds have since been produced, inspired by THC, which have been designed to elicit similar pharmacological responses, and therefore are beneficial as analgesics. These compounds are known as synthetic cannabinoids.
Synthetic cannabinoids, while potentially useful as therapeutic treatments for pain, are currently also popular as recreational drugs. Herbal products that contain synthetic cannabinoids are sold as “legal highs,” as few of these compounds are illegal according to the Controlled Drugs and Substances Act. These products are prepared by combining synthetic cannabinoids and plant material, and are smoked similar to marijuana. As the legality of many synthetic cannabinoids is quickly decreasing, as evidenced by the March 2011 emergency scheduling of five such compounds, it is becoming increasingly likely that these products will soon become popular exhibits to be submitted to controlled substances laboratories for testing. If a previously smoked product is submitted, there could potentially be effects due to the burning, the presence of the plant or paper substrate, and other synthetic cannabinoids that could directly diminish the facility of analysis. The aim of this thesis was to investigate these effects using four synthetic cannabinoids (AM-2201, JWH-015, HU-211, and RCS-4) and four substrates (tobacco, rolling paper, mint, and rosemary).
Results demonstrated diminished peak areas, which are likely due to the introduction of these variables, which include burning the drug of abuse, and spiking the drug of abuse onto various matrices. The trend of lower peak areas further suggests that burning, the presence of plant material, and other cannabinoids potentially all compromise the facility of analyzing synthetic cannabinoid products. The act of burning one synthetic cannabinoid in particular, AM-2201, appeared to greatly decrease the capability to detect the analyte, as did the application of AM-2201 to various substrates. Furthermore, the ability to detect AM-2201 appeared to vary greatly between results obtained from analyzing samples applied to different substrates. Analysis of cannabinoid mixtures demonstrated that GC/MS analysis of different cannabinoids gave various peak areas although the concentrations remained consistent. Peak area ratios of cannabinoid mixtures that were extracted from substrates were found to not differ significantly between the specific substrates studied. This research supports that all of these variables should therefore be considered in regards to analysis of herbal products containing synthetic cannabinoids
A Survey of Technology Usage by Businesses in Regional Thailand
This paper reports the preliminary results of an exploratory survey of information technology usage by businesses located in regional Thailand. With growing concern about the digital divide, Thailand is an important and interesting region to study. There has been very little prior research that has examined the take-up of information technology in this region. The research context for this study is particularly important for two reasons. Firstly, Thailand is considered a rapidly developing country in the Asia Pacific region and, secondly, the regional area of Chiang Mai where the survey was conducted has a population of less than 5% of that of Bangkok the capital of Thailand. The results of this study show a high rate of technology acceptance and use. The findings also indicate that the Internet has achieved wide acceptance as a means of doing business.Full Tex
Consensus on occupational health competencies for UK first contact physiotherapists
Background: Patients at risk of preventable sickness absence frequently attend at primary care. First contact physiotherapists (FCP) may provide an optimal way of reducing this risk; however, there is significant variability in clinical practice, limited research directing best practice and this work and health role is traditionally seen as outside of the ‘therapeutic relationship’. If FCP's training and development in this area is considered, FCP's will be able to effectively conduct fitness for work and sickness absence certification within UK primary care settings. Aims: This study aimed to reach expert consensus for work-related competencies for FCP practice for patients at risk of preventable sickness absence. Methods: A modified Delphi technique involved a UK-wide FCP expert panel completing three rounds of an online questionnaire. The initial 30-competency questionnaire, based on two separate Nominal Group Techniques in a FCP and Association of Chartered Physiotherapists in Occupational Health and Ergonomics (ACPOHE) physiotherapist cohort and Health Education England's published Roadmap to Practice, covered occupational health specific items (knowledge and skills) related to the topic. Consensus threshold was set a priori at 70% level of group agreement. Items not reaching consensus were modified and new items added based on themes from qualitative data from the open-ended free text questions present in each section. Items that reached values greater than or equal to 70% of agreement among experts were considered definitive for the competency items. Items between 51% and 69% of agreement were included for the next round and those items with less than or equal to 50% of agreement were considered unnecessary and were excluded. In the third round, the occupational health (OH) specific contents for primary care were classified according to the degree of consensus as follows: strong (≥70% of agreement), moderate (51–69% of agreement) and weak (50% of agreement) based on the maximum consensus reached. Results: Of the 30 initial competencies, 20 (67%) reached a strong degree of consensus and 2 (7%) reached a moderate degree of consensus and 8 (27%) competencies were not recommended (≤50% of agreement). 20 OH specific competencies reached a priori consensus level of agreement to provide the final group list. Conclusions: This paper provides an empirically derived list of OH competencies for FCP education in primary care ‘first point of care’ physiotherapy with a high level of expert agreement and high retention rate between rounds. Contribution of the paper: • The role of certifying sickness absence and providing fitness for work advice within primary care settings has normally been conducted by General Practitioners, largely due to the legislative aspects that require a ‘Fit Note’. • FCPs may be ideally suited in ensuring that work is considered at an early stage to help support and prompt conversations about work. • Most individual's health needs are addressed within Primary Care (first point of contact in the NHS). • There is a lack of empirical evidence on the competencies needed for the new ‘first point of contact role’ whereby FCPs manage undiagnosed and undifferentiated musculoskeletal (MSK) conditions.</p
Scaling-up process-oriented guided inquiry learning techniques for teaching large information systems courses
Promoting engagement during lectures becomes significantly more challenging as class sizes increase. Therefore, lecturers need to experiment with new teaching methodologies to embolden deep learning outcomes and to develop interpersonal skills amongst students. Process Oriented Guided Inquiry Learning (POGIL) is a teaching approach that uses highly structured group work during lessons so that students construct content. Each group member takes on a role for which the other group members rely on, and then the group reports back to the class. This paper describes how POGIL was adapted for use in a large first year Information Systems course. Quantitative and qualitative results suggest that students are receptive to POGIL, as the approach creates a relaxed, friendly and trusting community that is typically not present in classes that use a didactic teaching style. We provide a discussion of lessons learned with regard to using POGIL in a large lecture theatre and give recommendations for how to improve interactivity amongst the class
Who Cares and does it matter for the labour market? A longitudinal analysis of the labour force status of Indigenous and non-Indigenous carers
Indigenous Australians experience higher rates of severe or profound disability than other Australians, and the gap in rates of disability between Indigenous and non-Indigenous Australians increases with age. The relativelyhigh rates of disability among the Indigenous population corresponds with heavy caring burdens. It has been well established that carers of a person with a disability have lower rates of paid employment than dononcarers. However, relatively little is known about the effect of caring on the employment rates of Indigenous carers and virtually nothing about the effect of caring on changes in labour force status. This paper uses the recently released Australian Census Longitudinal Dataset to, for the first time, describe the labour market dynamics of Indigenous and non-Indigenous carers, and the extent to which these differ from the dynamics of thosewho are not carers. By exploiting the longitudinal nature of the data, we can examine how labour force status changes in association with starting as a carer and exiting from caring. Employment probabilities and labour force transitions are analysed using bivariate and multivariate techniques. The analysis raises questions about how caring decisions are made within households and the extent to which the costs of caring may differ between Indigenous and non-Indigenous households
There’s a standard for that: Aligning academic aspirations, professional standards, and ALA accreditation
The Syracuse University library and information science (LIS) program has committed to a new focus on INformation Justice, Equity, and Community EngagemenT (INJECT) that will guide a redesign of our program and redefine our commitment to our students, our coursework, and our impact on the information profession and broader community. While INJECT concepts form the bedrock of our new curriculum, our program is committed to being responsive to library professional standards as well as the ALA Standards for Accreditation of Master’s Programs in Library and Information Studies. Professional standards produced by library associations including ALA, IFLA, ACRL, SLA, RUSA, and YALSA reflect the needs of the library profession and impact the knowledge, skills, abilities, and dispositions librarians need to learn. In designing professional curriculum, LIS faculty must respond to and design for existing standards and competency lists in order to create a program that correlates with the ideals held by various library organizations. At the same time, LIS programs must demonstrate alignment with ALA Standards for Accreditation. So, how do the various competency lists compare to accreditation standards? How do the competencies and standards support INJECT topics, including critical librarianship, social justice, and equity and where do they fall short? This poster reveals an analysis and alignment of professional standards, accreditation standards, and our aspirations to better represent information justice, equity, and community engagement in LIS. This work can enable faculty to transform LIS curricula and create a resilient future for our programs, our student, and the broader LIS profession
