The influence of dependability in cloud computing adoption
No full textCloud computing (CC) has many benefits, so its use has spread rapidly, particularly in the business sector. An important consideration in the acceptance of CC is whether the CC system is dependable, and it can differ among industry and service type. However, little research has considered the effect of dependability (composed of availability, reliability, security, maintainability) on CC acceptance. Especially, group comparisons between high IT-intensive (Hi-ITi) and low IT-intensive (Lo-ITi) industries have not been reported, nor have comparisons between software-as-a-service (SaaS) and platform-as-a-service (PaaS)/infrastructure-as-a-service (IaaS). This study aims to explore how the dependability of CC affects users' intent to accept it, with focus on how this intent is affected by intensity of IT use (by industry) and by the type of CC service used. To validate the proposed model, this study applied structural equation modeling and conducted multi-group analysis. A total of 230 business managers in South Korea represent the sample for our study. For the full dataset, the three dependability attributes (availability, reliability, security) do not affect the usefulness of CC, but do affect the ease of use of CC. The usefulness of CC is a determinant for positive intention to accept CC, whereas the ease of use of CC is not. Maintainability is the strongest determinant of CC adoption for the full dataset, and for all individual groups, except those that use SaaS. For Hi-ITi and Lo-ITi industries, results show that managers show no differences in their perceptions of the effect of dependability attributes (availability, reliability, security) on the usefulness and the ease of CC. The absence of such a difference in managers' perception also applies to the relationship between two core variables of TAM (i.e., perceived usefulness, perceived ease of use) and behavioral intention to accept CC. For SaaS and PaaS/IaaS, managers have different perceptions of security on the usefulness of CC, and the effect of the usefulness of CC on the intention to accept CC. The findings can provide academic researchers and industry practitioners with a differentiated and in-depth perspective on the understanding and the spread of CC.11Nsciescopu
Antiplatelet drugs in cardiological practice: Established strategies and new developments
No full textFlorian Krötz, Hae-Young Sohn, Volker KlaussCardiology, Medical Policlinic, Ludwig-Maximilians-Universität, Ziemssenstr. 1, 80336 MünchenAbstract: A common pathophysiological course in vascular diseases is an overwhelming activation and aggregation of blood platelets, which results in atherothrombosis. By causing the last decisive step of cerebral, coronary, or peripheral arterial ischemia thrombotic complications of atherosclerotic disease represent a major player in death cause statistics of most western countries. The development of novel therapies against platelet-dependent thrombosis and the concurrent improvement of existing therapeutic strategies thus is a paramount focus of pharmaceutical research. Currently, efficiency, dosing and indications of established antiplatelet substances are being re-evaluated, whilst new, so far unrecognized molecular targets for inhibition of platelet activity come up front. This not only allows for interesting new therapeutical options, but also widens our insight into the role platelets play in atherosclerosis in general. This article summarizes the relevant pathophysiology of platelet activation, presents current concepts in antiplatelet drug therapy, and highlights the role of platelets in vascular diseases apart from atherothrombosis.Keywords: atherothrombosis, antiplatelet drug therapy, pathophysiology, platelet activatio
Views of children and young people in foster care survey: education
No full textThis paper explores the educational experiences of children and young people living in foster care in Queensland. Findings are drawn from the responses of 845 children and 1180 young people to the 2011 Views of Children and Young People in Foster Care survey, which is a rich source of information about children’s and young people’s attitudes towards and perceptions of their own education. Findings relate to educational status, key markers of educational disadvantage including suspensions and exclusions, and specific problems children and young people experience at school, as well as children’s and young people’s enjoyment of school and aspirations for the future. Information about educational support, including Educational Support Plans and support provided by Child Safety Officers and Community Visitors are also presented. Where relevant, comparisons are made between the 2011 survey results and prior surveys conducted in 2006, 2007 and 2009. Relationships between key educational measures as well as relationships to other important measures of health and placement stability are also explored.
The findings suggest that children and young people continue to experience educational disadvantage, including high rates of suspension and exclusion and a range of problems at school including problems with schoolwork, bullying and behaviour and that these difficulties can be exacerbated by the child protection system, for example, through placement instability. However, there are reasons for optimism. Children and young people are overwhelmingly likely to report that they enjoy school, expect to complete Year 12 and that their teachers generally like their schoolwork. Furthermore, over time, the proportions of young people reporting that they have an Educational Support Plan have grown, and, importantly, they are more likely to report that these plans are helpful. Analyses in relation to a number of educational variables reveal that young people with a plan they consider to be helpful fare better. Children and young people were also positive about the important role that CSOs and CVs are able to play in supporting their education.
While educational disadvantage is an enduring problem, the survey findings provide evidence of progress in key areas and suggestions for how continued improvements may be made
Nicky Sohn oral history interview and transcript
No full textThis recording and transcript form part of a collection of oral history interviews conducted by the Chao Center for Asian Studies at Rice University. This collection includes audio recordings and transcripts of interviews with Asian Americans native to or living in Houston.Nicky Sohn was born in Seoul, Korea in 1992. She began practicing piano and studying music from a very young age; after moving around a lot with her parents in the southern part of the country, she graduated high school early and went to Mannes School of Music in New York City at the age of 16. She initially studied piano performance but switched to composition; after graduating from Mannes in 2014, she obtained her master's degree at Julliard, completing it in 2016. Afterward, she moved to LA to study at UCLA. During this time, she took upon numerous commissions from various institutions, including the Stuttgart Ballet in Germany as well as the National Theater of Korea; she also garnered various honors in competitions and festivals across the country as well as in Europe. After
living in Berlin for a short period of time, she came to Houston in 2019 to pursue her doctorate in composition at Rice's Shepherd School of Music. So far in Houston, she's taken commissions from arts institutions (such as the Contemporary Arts Museum and the Moody Center for the Arts) across the city as well as through the DaCamera Young Artist Program, through which she's also participated in various community music programs. In this interview, Sohn discusses moving a lot, her relationship with her parents and home country, her education, the prejudices she's encountered in the art music world, her working process for and learning experiences with composing, the fun of collaboration, what it means to be a "Korean" composer, her extramusical hobbies and life during quarantine, music she loves, and more

High-Performance Work Systems and Ambidextrous Capability and Innovation Performance : The Moderating Role of a Innovative Organizational Culture
No full textStrategic hunam resource management studies are increasingly growing to uncover the mechanism between high-performance work systems and firm innovation. The purpose of this study is to investigate the effects of high-performance work systems on ambidextrous capability and innovation performance. In addition, we examined the moderating effect of innovative organizational culture. Building on literature review regarding these constructs, Research hypotheses were set up through previous studies. hypotheses are developed and tested with 306 samples using Hierarchical regression analyses. As a result of analysis, first, high-performance work systems have a significant effect on ambidextrous capability. Second, ambidextrous capability has significant influence on innovation performance. Third, Innovative organizational culture has a moderating effect between high-performance work systems and ambidextrous capability. The results were to identify the role of ambidextrous capability as a link between the company 's high-performance work systems and innovation performance. In addition, Innovative organizational culture provides important implications in that it identifies mechanisms between high-performance work systems and ambidextrous capability. In the final conclusion section, implications and limitations of research results and suggestions for future research are discussed.22Nkc
