Investigating spintronics thin film systems with synchrotron radiation
2009
Abstract Spintronics is a research field involving a wide variety of different magnetic materials. Synchrotron radiation in the VUV and soft X-ray regime is ideally suited to investigate the relationships between magnetic properties and electronic structure of spintronics thin film stacks. Complex layered structures and nanomagnets are the main building blocks for current and future spintronics applications. In this contribution we describe the study of spintronics model systems with respect to the static and dynamic behavior with an emphasis on interfaces.
Bubbles in China
2010
This study examines rational bubbles in Chinese stock markets and China-related share indices in Hong Kong. A duration dependence test is employed for both monthly and weekly abnormal market returns of the Shanghai and Shenzhen A- and B-markets, as well as for the Hong Kong China Enterprises and China Affiliated Corporations indices. The test results are mixed, as weekly data demonstrate bubbles for all of the Mainland Chinese stock markets, but monthly data do not show bubbles for any of the examined markets. Neither of the datasets indicates bubbles in the Hong Kong markets. Results indicate that, in terms of bubbles, segmentation does not play a significant role in bubble existence and t…
The process by which perceived autonomy support predicts motivation, intention, and behavior for seasonal influenza prevention in Hong Kong older adu…
2017
Background: This study examined the effectiveness of a theoretical framework that integrates self-determination theory (SDT) and the theory of planned behavior (TPB) in explaining the use of facemasks to prevent seasonal influenza among Hong Kong older adults. Methods: Data were collected at two time points in the winter in Hong Kong, during which influenza is most prevalent. At Time 1, older adults (N = 141) completed self-report measures of SDT (perceived autonomy support from senior center staff, autonomous motivation for influenza prevention) and TPB (attitude, subjective norm, perceived behavioral control, and intention for influenza prevention) constructs with respect to facemask used…

Emergence of tularemia in France: paradigm of the Burgundy region
2011
International audience; We report three consecutive cases of tularemia occurring in Burgundy, France, a region previously considered not endemic for tularemia. The patients presented with varied and unspecific clinical manifestations. The epidemiological circumstances, especially the mode of contamination, were not particularly suggestive of tularemia. Serological diagnosis was delayed in two cases because of the lack of significant antibody titers at the time of admission. In contrast, a diagnosis could readily be obtained in all three cases by detection of Francisella tularensis DNA from clinical samples using PCR-based methods. These cases highlight the increased incidence and geographic…
Social Ecological Model of Problem Gambling : A Cross-National Survey Study of Young People in the United States, South Korea, Spain, and Finland
2021
Problem gambling among young people is an emerging trend globally. The online environment in particular offers various possibilities for gambling engagement. This is the first cross-national survey study using the social ecological model to analyze problem gambling, especially in the online context. The study aimed to analyze how different social ecological spheres explain problem gambling. Participants were young people aged 15–25 in the United States (n = 1212), South Korea (n = 1192), Spain (n = 1212), and Finland (n = 1200). The South Oaks Gambling Screen (SOGS) instrument measured problem gambling. The regression models analyzed problem gambling with measures of intrapersonal, interper…
Can't simply roll it out: Evaluating a real-world virtual reality intervention to reduce driving under the influence.
2020
Driving under the influence (DUI) increases the risk of crashes. Emerging technologies, such as virtual reality (VR), represent potentially powerful and attractive tools for the prevention of risky behaviours, such as DUI. Therefore, they are embraced in prevention efforts with VR interventions primed to grow in popularity in near future. However, little is known about the actual effectiveness of such DUI-targeting VR interventions. To help fill the knowledge gap, this study explored the effects of one VR intervention as delivered in the real world. Using pre and post test design, including an intervention group (n = 98) and a control group (n = 39), the intervention evaluation examined you…
Timing of surgery following SARS-CoV-2 infection: an international prospective cohort study
2021
Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231…
School-entry language outcomes in late talkers with and without a family risk of dyslexia.
2020
Children with familial risk (FR) of dyslexia and children with early language delay are known to be at risk for later language and literacy difficulties. However, research addressing long‐term outcomes in children with both risk factors is scarce. This study tracked FR and No‐FR children identified as late talkers at 2 years of age and reports development from 4;6 through 6 years. We examined the possible effects of FR‐status and late talking (LT) status, respectively, on language skills at school entry, and whether FR‐status moderated the associations between 4;6‐year and 6‐year language scores. Results indicated an effect of LT status on language at both ages, while FR status affected lan…
The Impact of Business Group Affiliation and Country-Level Institutions on Corporate Governance of Emerging Market Firms
2020
This study outlines how the corporate governance of emerging market firms is influenced by corporate affiliation and institutional embeddedness. We argue that the stronger the business group affiliation, the less likely is the emerging market firm to adopt shareholder value enhancing corporate governance, and that this relationship is moderated by institutional quality and tribalism. Based on189 initial public offerings (IPOs) from 22 African countries between 2000and 2016, we find a significant negative relationship between business group ownership and IPO firms’ quality of corporate governance. We also find this relationship to be significantly negatively moderated by country-level instit…
