BACKGROUND: Though direct oral anticoagulants (DOACs) have become a standard of care in the treatment of acute deep vein thrombosis (DVT), it is our observation that physicians tend to initiate heparin or low-molecular-weight heparin, hereafter called “heparin”, for the treatment of extensive DVT or phlegmasia cerulea dolens (PCD). This might be due to a perception that heparin might relieve DVT-related symptoms more quickly than DOACs. Whether these assumptions are true has not been evaluated. METHODS: We conducted a survey of thrombosis specialists in North America to explore the practical management of anticoagulant therapy in patients with extensive DVT, and the underlying reasons for the selection of heparin over DOACs. A cross-sectional, web-based survey was distributed to thrombosis specialists who are members of four thrombosis societies. RESULTS: Eighty-nine respondents provided consent. Most respondents selected DOACs over heparin in a case scenario representing mild DVT-related symptoms and limited thrombus involvement (81% vs. 19%). Most respondents selected heparin over DOACs in a case scenario representing early stage PCD (84% vs.16.3%) or a patient with high bodyweight (72% vs. 28%). In a case scenario representing extensive DVT, 57.4% of the respondents selected heparin, whereas, 42.6% selected DOACs. In the respondents who selected heparin over DOACs, the major reason was that heparin might relieve DVT-related symptoms more quickly because of its anti-inflammatory effects. DISCUSSION: Severity of DVT-related symptoms, thrombus extent, and bodyweight play a role in the selection of anticoagulant therapy. Despite a lack of evidence to support the hypothesis with respect to which anticoagulant is superior, most thrombosis specialists selected heparin over DOACs in patients with severe DVT-related symptoms and extensive thrombus involvement. Observation of variations in the selection of anticoagulant therapy for the treatment of extensive DVT also indicates that clinical trials in this patient population are needed. / Thesis / Master of Science (MSc)

Yes / In the past it has been found that the maximum pass-by noise for the most noisy of vehicles can be 6-8 dB(A) above the average for the sample. It is therefore useful to consider the types of vehicle that make excessive noise and their condition and to reach some conclusions on how best to reduce the problem. Measurements of maximum noise, pass-by speed together with video footage were taken on a busy dual carriageway road (A34) in the UK carrying a high percentage of heavy vehicles. The intention was to collect sufficient information on light, medium heavy and heavy vehicles to enable typical characteristics of noisy vehicles to be identified. Peak noise levels produced by vehicles under normal operating conditions of steady speed were recorded and not of vehicle being driven in an aggressive manner e.g. under harsh acceleration. This paper reports on the characteristics of excessively noisy vehicles that were identified under these cruising conditions in free flow traffic conditions. / The work described in this report was carried out in the Noise and Vibration Team of TRL Limited under funding from the Transport Research Foundation.

The purpose of this study was to determine food safety knowledge and practices of older adult participants in the Food Stamp Nutrition Education Program (FSNEP) in Virginia. One hundred and sixty-five FSNEP participants were assigned to two possible intervention groups, group one received the food safety lesson from the Healthy Futures Series currently used in FSNEP, while group two received the food safety lesson plus an additional food safety video. FSNEP participants completed food safety knowledge and practices questionnaires at baseline and at the end of FSNEP program. Observations of some FSNEP participants were also made. Results of this study indicate the FSNEP program was effective in making positive changes in participants' food safety knowledge and practices. However, FSNEP participants have inadequate food safety practices in the areas of proper storage of leftovers and raw ground meat, maintenance of refrigerator temperatures and use of meat thermometers. These areas should be emphasized in future food safety lessons used in FSNEP. In addition, participants who received only the current food safety lesson used in FSNEP had higher gains in food safety knowledge and practices, than participants who received both the current lesson food safety lesson and the instructional food safety video. Also, no strong relationships between demographic variables and FSNEP participants' food safety knowledge and practices were found. / Master of Science

No / Increasing mail survey response using monetary incentives is a proven, but not always cost-effective, method in every population. This paper tackles the questions of whether it is worth using monetary incentives and the size of the inducement by testing a regression model of the impact of prepaid monetary incentives on response rates in consumer and organizational mail surveys. The results support their use and show that the inducement value makes a significant impact on the effect size. Importantly, no significant differences were found between consumer and organizational populations.

Yes / Child safeguarding and the appropriate identification of suspected victims represents a global phenomenon. Diagnostic imaging is acknowledged as a contributory diagnostic service but the role of the radiographer in the identification and escalation process is less well understood. Method: A Knowledge, Attitude and Practice (KAP) survey was constructed to evaluate knowledge base in the context of the patient–radiographer interaction, the shaping of attitude towards child safeguarding and attitudes held towards their role plus the actual practical experiences of managing child safeguarding concerns. Results: Respondents demonstrated a inconsistent knowledge base with respect to physical, social and radiographic signs and symptoms of child safeguarding concern. A positive attitude towards the role of the radiographer in child safeguarding was demonstrated but one that was shaped more by experience than pre-registration education. Assessment of concerns was chiefly influenced by clinical history and appreciation of aetiology. Practically, radiographers have infrequent involvement with the identification and escalation of concerns. Whilst some statistically significant relationships between responses and demographics did exist, these were either sporadic or argued to be a result of natural variation. Conclusion: Assessment of physical and social signs of child safeguarding concern are argued to be becoming more challenging. Radiological signs continue to be visible to radiographers but with increasing use of other imaging modalities these signs are becoming more varied in nature and are providing new challenges. Radiographers are capable of escalation when required to do so. Implications for practice: To maximise the contribution of the profession, education needs to account for imaging modality worked with, in combination with an understanding of related aetiology. Previously existing concerns with respect to escalating processes are no longer in evidence and radiographers are both willing and able to contribute to that process.

The paper analyses the sources of income measurement error in surveys with a unique data set. We use the Austrian 2008-2011 waves of the European Union "Statistics on income and living conditions" survey which provide individual information on wages, pensions and unemployment benefits from survey interviews and officially linked administrative records. Thus, we do not have to fall back on complex two-sample matching procedures like related studies. We empirically investigate four sources of measurement error, namely social desirabil- ity, sociodemographic characteristics of the respondent, the survey design and the presence of learning effects. We find strong evidence for a social desirability bias in income reporting, whereas the presence of learning effects is mixed and depends on the type of income under consideration. An Owen value decomposition reveals that social desirability is a major expla- nation of misreporting in wages and pensions, whereas sociodemographic characteristics are most relevant for mismatches in unemployment benefits.

Thesis deals with modern ways of surveys using advancing information technology and internet which makes surveys using web applications more effective. After a short review of public opinion history the summary of principal czech and forign survey organizations engaged in determination of survey rules are presented. Thesis follows with description of classic and modern data collecting methods. Main attention is devoted to on-line survey method. The description of method, possibilities of realization, positives and negatives and use of on-line questionnaire survey are presented. Final part of thesis si focused on on-line survey applying. The quality of this method is considered by sociological survey.

In the context of organizational development, surveys are important tools for learning about employees’ experiences in the organization. Organizational practice is faced with two main challenges to the successful implementation of surveys. First, the increasing use of surveys may lead to survey fatigue potentially negatively impacting employees’ motivation to engage in surveys. Second, survey results serve as a basis for strategic decision-making in organizations and thus need to be adequate for linkage research or benchmarking practices. The presented research aims to address these two challenges by taking a respondent-centered approach focusing on motivational and cognitive aspects of employees’ experiences while taking surveys. First, it introduces the new construct of survey experience as a respondent- centered criterion of successful survey design (Paper 1). A short-scale is theoretically developed based on user experience theory (Hassenzahl, Platz, Burmester, & Lehner, 2000) and empirically tested and validated in two studies. It, therefore, contributes to the understanding of survey design influences on participant’s motivational processes of survey response. Additionally, the short-scale equips practitioners with a reliable and economic lever to counter possible effects of survey fatigue by creating enjoyable and usable surveys tailored to specific target groups. Second, the presented research addresses cognitive and motivational aspects of survey processing and potential implications for the comparability of results. It, specifically, examines item-wording effects on response behavior on the example of intensifiers in Likert-type item stems of employee attitude surveys (Papers 2 and 3). It, further, considers the role of the organizational setting in determining employees’ response behavior (Krosnick, 1991) in the response process (Tourangeau & Rasinski, 1988) of employee attitude surveys (Paper 3). It, thereby, contributes to the understanding of employees’ response processes in this particular setting and provides practical advice for item-wording practices in organizations. Overall, the three papers bridge the previous literature by considering the survey itself, participants’ motivational and cognitive processes of survey response, and the survey setting in the context of employee attitude surveys together. The results of the presented research highlight the need for a contextual approach to researching and designing surveys that considers interactions between the survey, the participants, and the setting. It, thereby, contributes starting points to enable a more sophisticated approach to understanding survey response in employee attitude surveys.
