Information systems objectives: Perceptions of information systems developers of different cultures
An increasing number of corporations are developing and implementing information sys tems (IS) applications which cross national boundaries and span diverse cultures. As a result of the cultural differences, IS developers in different countries may have very different perceptions regarding the objectives of an IS. In the current study, developers from three countries - Japan, Taiwan, and the United States - rated the importance of eight objectives of a successful IS. The eight objectives are categorized by hierarchical levels, and also as short-term or long-term goals. The results indicated the IS developers viewed objectives at the system and organizational levels as more important than objectives at the user and strategic levels. Overall, the IS developers rated the short-term objectives as more important than the long-term objectives. There was no significant difference between the countries with respect to the perceived importance of the short-term/direct objectives. However, there were significant differences in the views of IS developers from the three countries regarding the perceived benefits of long-term/ indirect objectives of an IS
Rolling Adhesion of Yeast Engineered to Express Cell Adhesion Molecules
Selectins are cell adhesion molecules that mediate capture of leukocytes on vascular endothelium as an essential component of the inflammatory response. Here we describe a method for yeast surface display of selectins, together with a functional assay that measures rolling adhesion of selectin-expressing yeast on a ligand-coated surface. E-selectin-expressing yeast roll specifically on surfaces bearing sialyl-Lewisx ligands. Observation of yeast rolling dynamics at various stages of their life cycle indicates that the kinematics of yeast motion depends on the ratio of the bud radius to the parent radius (B/P). Large-budded yeast walk across the surface, alternately pivoting about bud and parent. Small-budded yeast wobble across the surface, with bud pivoting about parent. Tracking the bud location of budding yeast allows measurement of the angular velocity of the yeast particle. Comparison of translational and angular velocities of budding yeast demonstrates that selectin-expressing cells are rolling rather than slipping across ligand-coated surfaces
Machine learning for classifying and interpreting coherent X-ray speckle patterns
Speckle patterns produced by coherent X-ray have a close relationship with
the internal structure of materials but quantitative inversion of the
relationship to determine structure from speckle patterns is challenging. Here,
we investigate the link between coherent X-ray speckle patterns and sample
structures using a model 2D disk system and explore the ability of machine
learning to learn aspects of the relationship. Specifically, we train a deep
neural network to classify the coherent X-ray speckle patterns according to the
disk number density in the corresponding structure. It is demonstrated that the
classification system is accurate for both non-disperse and disperse size
distributions

Who uses the internet as a source of nutrition and dietary information? An Australian population perspective
Background: The Internet contains a plethora of nutrition information. Health organizations are increasingly using the Internet to deliver population-wide health information and interventions. Effective interventions identify their target population and their needs; however, little is known about use of the Internet as a source of nutrition information. Objective: The aim was to assess the change in prevalence and demographic characteristics of Western Australian adults accessing the Internet as a source of nutrition information and identify specific information needs. Methods: Data were pooled from the Western Australian Department of Health’s 3-yearly Nutrition Monitoring Survey Series telephone survey between 1995 and 2012 of 7044 participants aged 18 to 64 years. Outcome variables were the main sources of nutrition information used in the last year and yes/no responses to 4 suggestions to what would make it easier to eat a healthy diet. Sociodemographic variables were collected. Results: The proportion of respondents using the Internet for nutrition information increased from <1% in 1995-2001 to 9.1% in 2004 and 33.7% in 2012. Compared to 2004, logistic regression showed that the odds of using the Internet for this information increased significantly in 2009 (OR 2.84, 95% CI 2.07-3.88) and 2012 (OR 5.20, 95% CI 3.86-7.02, P<.001). Respondents using the Internet as a source were more likely to be female (OR 1.30, 95% CI 1.05-1.60, P=.02), live in a metropolitan area (OR 1.26, 95% CI 1.03-1.54, P=.03), born in countries other than Australia/UK/Ireland (OR 1.41, 95% CI 1.07-1.85, P=.02), more educated (university: OR 2.46, 95% CI 1.77-3.42, P<.001), and were less likely to be older (55-64 years: OR 0.38, 95% CI 0.25-0.57, P<.001). The majority of respondents agreed the following information would assist them to make healthier choices: more ways to prepare healthy foods (72.0%, 95% CI 70.7-73.3), quicker ways to prepare healthy foods (79.0%, 95% CI 77.8-80.1), how to choose healthy foods (68.8%, 95% CI 67.5-70.1), and knowing more about cooking (54.7%, 95% CI 53.3-56.1). Those using the Internet for nutrition information were more likely than nonusers to want to know quicker ways to prepare healthy foods (83.0% vs 78.1%, P=.005) and information on choosing healthy foods (76.3% vs 67.3%, P<.001)
More than rugby: A scoping review of coaches in rugby
Introduction
It is well-recognised that fulfilling the role of a coach is multi-faceted. In rugby, some of these coaching facets have been studied, however the research has not been reviewed. Reviewing the literature on rugby coaches will inform and guide policies, coach education, research and practice. Therefore, the purpose of this study is to provide a scoping review of the current coach focused literature on rugby union, rugby league and rugby sevens.
Methods
A scoping review was conducted on five electronic databases (EBSCOhost, PubMed, Scopus, SPORTDiscus, Web of Science) until January 2022 using the PRISMA-ScR guidelines. Participants had to be coaches within rugby union, sevens and league to be included. Data were extracted and analyzed to form a numerical and thematic summary.
Results
105 articles were included. 76% of the studies were on rugby union, 14% on league, 1% on sevens and the remainder focused on a combination of rugby cohorts or did not specify. Three themes were identified via a thematic analysis based on the content of the articles, these were coach knowledge (68%), coach pedagogies (29%), and coach development (4%).
Conclusion
The main finding in this review is that research on rugby coaches understood the risk, prevention, and management of injuries. Educational resources should include all aspects of rugby play or training injuries. The importance of the athlete-coach relationship and coach reflective practices was another significant finding. Coaches are encouraged to have a broad understanding of various aspects related to the player's welfare, which can be developed using formal and/or nonformal learning
Social Climber attachment in forming networks produces phase transition in a measure of connectivity
Formation and fragmentation of networks is typically studied using
percolation theory, but most previous research has been restricted to studying
a phase transition in cluster size, examining the emergence of a giant
component. This approach does not study the effects of evolving network
structure on dynamics that occur at the nodes, such as the synchronization of
oscillators and the spread of information, epidemics, and neuronal excitations.
We introduce and analyze new link-formation rules, called Social Climber (SC)
attachment, that may be combined with arbitrary percolation models to produce a
previously unstudied phase transition using the largest eigenvalue of the
network adjacency matrix as the order parameter. This eigenvalue is significant
in the analyses of many network-coupled dynamical systems in which it measures
the quality of global coupling and is hence a natural measure of connectivity.
We highlight the important self-organized properties of SC attachment and
discuss implications for controlling dynamics on networks.Comment: 6 pages, 4 figure
COVID-19: how has a global pandemic changed manual therapy technique education in chiropractic programs around the world?
Background
Manual therapy is a cornerstone of chiropractic education, whereby students work towards a level of skill and expertise that is regarded as competent to work within the field of chiropractic. Due to the COVID-19 pandemic, chiropractic programs in every region around the world had to make rapid changes to the delivery of manual therapy technique education, however what those changes looked like was unknown.
Aims
The aims of this study were to describe the immediate actions made by chiropractic programs to deliver education for manual therapy techniques and to summarise the experience of academics who teach manual therapy techniques during the initial outbreak of COVID-19 pandemic.
Methods
A qualitative descriptive approach was used to describe the immediate actions made by chiropractic programs to deliver manual therapy technique education during the COVID-19 pandemic. Chiropractic programs were identified from the webpages of the Councils on Chiropractic Education International and the Council on Chiropractic Education – USA. Between May and June 2020, a convenience sample of academics who lead or teach in manual therapy technique in those programs were invited via email to participate in an online survey with open-ended questions. Responses were entered into the NVivo software program and analysed using a reflexive thematic analysis by a qualitative researcher independent to the data collection.
Results
Data from 16 academics in 13 separate chiropractic programs revealed five, interconnected themes: Immediate response; Move to online delivery; Impact on learning and teaching; Additional challenges faced by educators; and Ongoing challenges post lockdown.
Conclusion
This study used a qualitative descriptive approach to describe how some chiropractic programs immediately responded to the initial outbreak of the COVID-19 pandemic in their teaching of manual therapy techniques. Chiropractic programs around the world provided their students with rapid, innovative learning strategies, in an attempt to maintain high standards of chiropractic education; however, challenges included maintaining student engagement in an online teaching environment, psychomotor skills acquisition and staff workload

configuration before the LHC start. The space and time alignment and the
measurement of chamber efficiency, time resolution and cluster size are
described in detail. The results are in agreement with the expected detector
performance.Comment: Submitted to JINST and accepte
Structural factors controlling the spin-spin exchange coupling: EPR spectroscopic studies of highly asymmetric trityl-nitroxide biradicals
Highly asymmetric exchange-coupled biradicals, like the trityl-nitroxides (TN), possess particular magnetic properties opening new possibilities for their application in biophysical, physicochemical and biological studies. In the present work, we investigated the effect of the linker length on the spin-spin coupling interaction in TN biradicals using the newly synthesized biradicals CT02-GT, CT02-AT, CT02-VT and CT02-PPT as well as the previously reported biradicals TNN14 and TN1. Results show that the magnitude of the spin-spin interaction (J) can be easily tuned from ~ 4 G (conformer 1 in CT02-PPT) to over 1200 G (in TNN14) using various linkers separating the two radical moieties and with varying temperature. Computer simulation of EPR spectra was carried out to directly estimate J values of the TN biradicals. In addition to the spin-spin coupling interaction of TN biradicals, their g, hyperfine splitting and zero-field splitting interactions were explored at low temperature (220 K). Our present study clearly shows that the spin-spin interaction variation as a function of linker distance and temperature provides an effective strategy to develop new TN biradicals which can find wide applications in relevant fields
