    In the 1980s, participation rates in health interview and health examination surveys were around 80% while now they are around 50-60%. There is also evidence that non-participation is selective. Low participation rates and selective non-participation may cause bias to our survey results based on participants alone. We aim to increase knowledge on cultural differences in acceptance and feasibility of different recruitment methods. The European Health Examination Survey Pilot Project, conducted in 2009-2012, included pilot surveys in 12 countries among people aged 25-64 years. Information about recruitment methods and participation rates in these surveys was collected. Participation rates ranged from 16% to 57% for men and from 31% to 74% for women, where in most surveys women had higher participation rates than men. A variety of recruitment and promotion methods were used to obtain as high participation rates as possible. Combinations of phone calls, invitation letter and home visits were used to recruit invitees. Obtaining valid phone numbers for survey invitees was difficult in several countries. Incentives, websites and promotion in local media were used to promote the surveys. The European Health Examination Survey Pilot surveys showed that obtaining a participation rate above 50% for a representative population sample is possible but it requires hard work and a well-planned recruitment strategy. Recruitment methods used in one country may not be possible to use in another country due to cultural norms and national regulations. © 2015 the Nordic Societies of Public Health.

    A high participation rate is considered as a prerequisite for representative survey results, especially when it is known that non-participation is selective. In many countries migration is increasing and the proportion of people speaking other language(s) than the official language(s) of the country is also increasing. How does this affect survey participation rates? Data from four cross-sectional health examination surveys (the FINRISK Study) were used to evaluate the effect of the registered mother tongue to participation in the survey. Finland has two official languages (Finnish and Swedish). Between 1997 and 2012, the proportion of the population with some other language as their registered mother tongue has increased significantly. Participation rates in the health surveys have been highest among the Finnish language group (68% in men in 1997 and 76% in women in 1997), while lowest among the foreign language group (43% in men in 1997 and 57% in women in 1997). In 2012, the participation rates had declined in all language groups: for men, 58%, 62% and 41% for Finnish, Swedish and foreign groups respectively, and for women 68%, 75% and 56%. The participation rate for the foreign language group was significantly lower than for the Finnish and Swedish groups. In future surveys it will be important to include actions to promote participation, e.g. providing survey material in several languages. These actions will increase costs but will be essential to ensure high participation rates and reliable results for the total population.

    Declining participation rates are an increasing problem in population surveys. Different kinds of methods have been used to ensure participation rates as high as possible. Monetary incentives and reminders have been found to be effective ways to increase participation rates, but these are rather expensive to implement in large population surveys. There is a need for cheaper ways to motivate survey invitees to participate. The Kuusamo Health Examination Survey was conducted in May-June 2011. A random sample of 250 people was selected for the survey. Mobile phone numbers, when available, were obtained for people within the sample. For a random sample of 50% of survey invitees with a mobile phone number, a short message service (SMS) reminder was sent prior to their appointment. All survey participants were asked to fill in a feedback questionnaire. Participation rate was 58% for men and 74% for women. Mobile phone numbers were available for 66% of the sample. Among those receiving an SMS reminder about their appointment, participation rates were up to 25 percentage points higher than among the group not receiving a reminder. In the feedback questionnaire, 9% of the survey participants reported that they would not have participated without the SMS reminder they received. Participants preferred morning hours and Monday-Tuesday as time and day options for the examinations. SMS reminder about the appointment time was an effective way to increase participation rate, especially among the youngest age groups also, providing flexible office hours for the examination clinic may increase participation rate. © 2014 the Nordic Societies of Public Health.

    Our study examined the effect of a ChinaYuan (CNY) 10 cash incentive on the participation rate in a face-to-face health survey among the general Chinese population. Subjects older than 15 years of age and had been living in the two selected districts for more than 6 months were selected using multistage random sampling. Participants from only one district received a cash incentive (CNY 10) for completing the survey. The participation rates in the nonincentive and incentive groups were 39.9% and 61.2%, respectively, P rate (54.4%); no significant difference was found between men (39.4%) and women (40.5%), P = 0.59. In the incentive group, the highest participation rate was observed in the ≥75 years (78.1%) age group. The cost for a completed interview was CNY 34.5 in the incentive group and CNY 35.8 in the nonincentive group. Cash incentives might increase participation rates in face-to-face surveys in China. The absolute cost was higher for the incentive group, whereas cost for a completed interview was actually the lowest. Furthermore, participation rate did not differ between men and women, but elders were more likely to participate in health surveys. Copyright © 2015 Elsevier Inc. All rights reserved.

    Health examination surveys (HESs), carried out in Europe since the 1950's, provide valuable information about the general population's health for health monitoring, policy making, and research. Survey participation rates, important for representativeness, have been falling. International comparisons are hampered by differing exclusion criteria and definitions for non-response. Information was collected about seven national HESs in Europe conducted in 2007-2012. These surveys can be classified into household and individual-based surveys, depending on the sampling frames used. Participation rates of randomly selected adult samples were calculated for four survey modules using standardised definitions and compared by sex, age-group, geographical areas within countries, and over time, where possible. All surveys covered residents not just citizens; three countries excluded those in institutions. In two surveys, physical examinations and blood sample collection were conducted at the participants' home; the others occurred at examination clinics. Recruitment processes varied considerably between surveys. Monetary incentives were used in four surveys. Initial participation rates aged 35-64 were 45% in the Netherlands (phase II), 54% in Germany (new and previous participants combined), 55% in Italy, and 65% in Finland. In Ireland, England and Scotland, household participation rates were 66%, 66% and 63% respectively. Participation rates were generally higher in women and increased with age. Almost all participants attending an examination centre agreed to all modules but surveys conducted in the participants' home had falling responses to each stage. Participation rates in most primate cities were substantially lower than the national average. Age-standardized response rates to blood pressure measurement among those aged 35-64 in Finland, Germany and England fell by 0.7-1.5 percentage points p.a. between 1998-2002 and 2010-2012.

    Full Text Available Background. The participation of general practitioners (GPs is essential in research on the performance of primary care. This paper describes the implementation of a large, multicountry study in primary care that combines a survey among GPs and a linked survey among patients that visited their practice (the QUALICOPC study. The aim is to describe the recruitment procedure and explore differences between countries in the participation rate of the GPs. Methods. Descriptive analyses were used to document recruitment procedures and to assess hypotheses potentially explaining variation in participation rates between countries. Results. The survey was implemented in 31 European countries. GPs were mainly selected through random sampling. The actual implementation of the study differed between countries. The median participation rate was 30%. Both material (such as the payment system of GPs in a country and immaterial influences (such as estimated survey pressure are related to differences between countries. Conclusion. This study shows that the participation of GPs may indeed be influenced by the context of the country. The implementation of complex data collection is difficult to realize in a completely uniform way. Procedures have to be tuned to the context of the country.

    Full Text Available Abstract Background Investigators conduct survey studies for a variety of reasons. Poor participant response rates are common, however, and may limit the generalizability and utility of results. The objective of this study was to determine whether direct approach with a tablet device enhances survey study participant response rate and to assess participants’ experiences with this mode of survey administration. Findings An interventional study nested within a single center survey study was conducted at McMaster Children’s Hospital. The primary outcome was the ability to achieve of a survey study response rate of 70% or greater. Eligible participants received 3 email invitations (Week 0, 2, 4 to complete a web-based (Survey Monkey survey. The study protocol included plans for a two-week follow-up phase (Phase 2 where non-responders were approached by a research assistant and invited to complete an iPad-based version of the survey. The Phase 1 response rate was 48.7% (56/115. Phase 2 effectively recruited reluctant responders, increasing the overall response rate to 72.2% (83/115. On a 7-point Likert scale, reluctant responders highly rated their enjoyment (mean 6.0, sd 0.83 [95% CI: 5.7-6.3] and ease of use (mean 6.7, sd 0.47 [95% CI: 6.5-6.9] completing the survey using the iPad. Reasons endorsed for Phase 2 participation included: direct approach (81%, immediate survey access (62%, and the novelty of completing a tablet-based survey (54%. Most reluctant responders (89% indicated that a tablet-based survey is their preferred method of survey completion. Conclusions Use of a tablet-based version of the survey was effective in recruiting reluctant responders and this group reported positive experiences with this mode of survey administration.

    Civic participation, that which directly influences important decisions in our personal lives, is considered necessary for developing a society. We hypothesized that civic participation might be related to self-rated health status. We constructed a multi-level analysis using data from the World Value Survey (44 countries, n=50 859). People who participated in voting and voluntary social activities tended to report better subjective health than those who did not vote or participate in social activities, after controlling for socio-demographic factors at the individual level. A negative association with unconventional political activity and subjective health was found, but this effect disappeared in a subset analysis of only the 18 Organization for Economic Cooperation and Development (OECD) countries. Moreover, social participation and unconventional political participation had a statistically significant contextual association with subjective health status, but this relationship was not consistent throughout the analysis. In the analysis of the 44 countries, social participation was of borderline significance, while in the subset analysis of the OECD countries unconventional political participation was a stronger determinant of subjective health. The democratic index was a significant factor in determining self-rated health in both analyses, while public health expenditure was a significant factor in only the subset analysis. Despite the uncertainty of its mechanism, civic participation might be a significant determinant of the health status of a country.

    Since 2004 NASA has surveyed users of its Earth Observing System Data and Information System (EOSDIS) to determine user satisfaction with its services. The surveys have been conducted by CFI Group under contract with the Federal Consulting Group, Executive Agent in government for the American Customer Satisfaction Index (ACSI). The purpose of these annual surveys is to help EOSDIS and the data centers assess current status and improve future services. The survey questions include demographic and experiential questions in addition to the ACSI and EOSDIS specific rating questions. In addition to customer satisfaction, analysis of each year's results has provided insight into the survey process. Although specific questions have been added, modified, or deleted to reflect changes to the EOSDIS system and processes, the model rating questions have remained the same to ensure consistency for evaluating cross year trends. Working with the CFI Group, we have refined the invitation and questions to increase clarity and address the different ways diverse groups of users access services at EOSDIS data centers. We present challenges in preparing a single set of questions that go to users with backgrounds in many Earth science disciplines. These users may have contacted any of the 12 EOSDIS data centers for information or may have accessed data or data products from many kinds of aircraft and satellite instruments. We discuss lessons learned in preparing the invitation and survey questions and the steps taken to make the survey easier to complete and to encourage increased participation.

    The National Health and Nutrition Survey, Japan, has annually monitored two indicators of physical activity in adults. They are contrasting in the association with age; the prevalence of exercise habit is lower and step counts are higher among younger participants. The present study aimed to examine the effects of rapid aging of the Japanese population and the lower participation rate among younger adults on the short-term trend of two indicators of physical activity using tabulated data. The prevalence of exercise habit and step counts by age groups (≥20 years) from 2003 to 2010 were estimated using tabulated data from the National Health and Nutrition Survey by calculating sex-specific means weighted by age-specific Japanese population data for each year (population-weighted estimates) and for a fixed year (2005; age-standardized estimates). Linear regression analyses were used to test the statistical significance of their trends. Statistically significant increasing trends in the prevalence of exercise habit were observed for the crude means (P = 0.029), the population-weighted estimates (P = 0.007) and the age-standardized estimates (P = 0.016) only in men. Statistically significant decreasing trends in the step counts were observed for the crude means (P = 0.006 in men and P = 0.033 in women) and the population-weighted estimates (P = 0.008 in men and P = 0.049 in women) both in men and women, but for the age-standardized estimates (P = 0.039) only in men. The effects of rapid aging of the Japanese population and the lower participation rate among younger adults on the short-term trend are not small, and age-standardization is necessary to observe even the short-term trend of physical activity data.

  14. Implementation of the forced answering option within online surveys: Do higher item response rates come at the expense of participation and answer quality?

    Full Text Available Online surveys have become a popular method for data gathering for many reasons, including low costs and the ability to collect data rapidly. However, online data collection is often conducted without adequate attention to implementation details. One example is the frequent use of the forced answering option, which forces the respondent to answer each question in order to proceed through the questionnaire. The avoidance of missing data is often the idea behind the use of the forced answering option. However, we suggest that the costs of a reactance effect in terms of quality reduction and unit nonresponse may be high because respondents typically have plausible reasons for not answering questions. The objective of the study reported in this paper was to test the influence of forced answering on dropout rates and data quality. The results show that requiring participants answer every question increases dropout rates and decreases quality of answers. Our findings suggest that the desire for a complete data set has to be balanced against the consequences of reduced data quality.

    To determine the survey-related experiential and attitudinal correlates of future health-related survey participation. From July 21, 2005, through October 25, 2005, we conducted a mixed-mode mail and telephone survey of 1636 noninstitutionalized Minnesota residents aged 18 years or older. The overall response rate was 49%. We examined the unadjusted effect of each independent variable on the likelihood of future participation in health-related surveys using univariate logistic regression and discerned the relative contribution of the different variables with multivariate logistic regression analysis. Respondents were asked to complete an average of 4.5 different surveys in the year before the current survey; approximately a quarter of the respondents perceived these surveys to be burdensome. The likelihood of future participation in health-related surveys was negatively related to good health status, a busy schedule, and perceptions that the surveys were too long. Respondents were more than twice as likely to indicate that they would participate in a future health-related survey if they knew the organization doing the survey. For health-related surveys, investigators should remain mindful of people's busy schedules and keep their surveys as short as possible. Further research is needed to clarify whether the decision to participate in a survey hinges more on knowing the organization paying to have a survey performed (the sponsor) or the survey vendor collecting the data.

    Prior research involving response rates in Web-based surveys has not adequately addressed the effect of the reputation of a sponsoring corporation that contracts with a survey provider. This study investigates the effect of two factors, namely, the reputation of a survey's provider and the reputation of a survey's sponsoring corporation, on the willingness of potential respondents to participate in a Web survey. Results of an experimental design with these two factors reveal that the sponsoring corporation's and the survey provider's strong reputations can induce potential respondents to participate in a Web survey. A sponsoring corporation's reputation has a greater effect on the participation willingness of potential respondents of a Web survey than the reputation of the survey provider. A sponsoring corporation with a weak reputation who contracts with a survey provider having a strong reputation results in increased participation willingness from potential respondents if the identity of the sponsoring corporation is disguised in a survey. This study identifies the most effective strategy to increase participation willingness for a Web-based survey by considering both the reputations of the sponsoring corporation and survey provider and whether to reveal their identities.

    We have developed a method to determine the transient surface density and transient rate for any given survey, using Monte-Carlo simulations. This method allows us to determine the transient rate as a function of both the flux and the duration of the transients in the whole flux-duration plane rather than one or a few points as currently available methods do. It is applicable to every survey strategy that is monitoring the same part of the sky, regardless the instrument or wavelength of the survey, or the target sources. We have simulated both top-hat and Fast Rise Exponential Decay light curves, highlighting how the shape of the light curve might affect the detectability of transients. Another application for this method is to estimate the number of transients of a given kind that are expected to be detected by a survey, provided that their rate is known.

    The survey provided by the College of American Pathologists (CAP) is chosen as one of the proficiency testing programs in Japan, and, recently, the numbers of participating facilities have increased. CAP provides 754 programs, and more than 1,000 tests were provided in 2014. Materials are translated as the "CAP global inter-laboratory comparison program" under the instruction of the Japanese Society of Laboratory Medicine (JSLM) selected from CAP surveys in Japan, and 68 programs and 261 items are provided. The total number of participating facilities was 174. CAP itself and the other services CAP provides are not well-known, while recognition of "the CAP survey as the proficiency test" has increased. The question "What is CAP and the CAP survey" was analyzed as a result of the questionnaire surveys conducted in 2014, and the advantage of the CAP survey and how to utilize it were considered. A questionnaire survey was conducted about the CAP survey for Japanese participants in 2014. Fifty-three questions were asked about their satisfaction level, intended use, and improvement. Eighty replies were analyzed. As a result, most CAP survey participants are satisfied. They intend to mainly use the CAP survey for their quality control. Furthermore, they can continuously monitor their systems throughout all testing phases as the survey has numbers of shipments a year and several specimens per each mailing. This helps in laboratory performance improvement. The Evaluation and Participant Summary (PSR) also effectively improves the laboratories' performance. CAP-accredited laboratories are required to participate in all survey programs concerning the test menu which they provide. Therefore, they have become accustomed to reviewing the evaluation and performing self-evaluation with a high usage rate of the Evaluation and PSR of the CAP survey. The questionnaire proved that performing the CAP survey properly enhanced the laboratories' quality control, and this meets the

    Full Text Available Abstract Background Epidemiological and other studies that require participants to respond by completing a questionnaire face the growing threat of non-response. Response rates to household telephone surveys are diminishing because of changes in telecommunications, marketing and culture. Accordingly, updated information is required about the rate of telephone listing in directories and optimal strategies to maximise survey participation. Methods A total of 3426 households in Sydney, Australia were approached to participate in a computer assisted telephone interview (CATI regarding their domestic (recycled and/or drinking water usage. Only randomly selected households in the suburb and postcode of interest with a telephone number listed in the Electronic White Pages (EWP that matched Australian electoral records were approached. Results The CATI response rate for eligible households contacted by telephone was 39%. The rate of matching of electoral and EWP records, a measure of telephone directory coverage, was 55%. Conclusion The use of a combination of approaches, such as an advance letter, interviewer training, establishment of researcher credentials, increasing call attempts and targeted call times, remains a good strategy to maximise telephone response rates. However, by way of preparation for future technological changes, reduced telephone number listings and people's increasing resistance to unwanted phone calls, alternatives to telephone surveys, such as internet-based approaches, should be investigated.

    In recent years, reduced participation has been encountered across all epidemiological study designs, both in terms of non-response as well as refusal. A low response rate may reduce the statistical power but, more importantly, results may not be generalizable to the wider community. In a telephone survey of 1413 randomly selected members of the Australian general population and of 690 participants sourced from previous studies, we examined factors affecting people's stated willingness to participate in health research. The majority of participants (61 %) expressed willingness to participate in health research in general but the percentage increased when provided with more specific information about the research. People were more willing if they have personal experience of the disease under study, and if the study was funded by government or charity rather than pharmaceutical companies. Participants from previous studies, older people and women were the groups most willing to participate. Younger men preferred online surveys, older people a written questionnaire, and few participants in any age and sex groups preferred a telephone questionnaire. Despite a trend toward reduced participation rates, most participants expressed their willingness to participate in health research. However, when seeking participants, researchers should be concrete and specific about the nature of the research they want to carry out. The preferred method of recommended contact varies with the demographic characteristics.

    2001-01-01

    This study tested the hypothesis that disparities in political participation across socioeconomic status affect health. Specifically, the association of voting inequality at the state level with individual self-rated health was examined. A multilevel study of 279,066 respondents to the Current Population Survey (CPS) was conducted. State-level inequality in voting turnout by socioeconomic status (family income and educational attainment) was derived from November CPS data for 1990, 1992, 1994, and 1996. Individuals living in the states with the highest voting inequality had an odds ratio of fair/poor self-rated health of 1.43 (95% confidence interval [CI] = 1.22, 1.68) compared with individuals living in the states with the lowest voting inequality. This odds ratio decreased to 1.34 (95% CI = 1.14, 1.56) when state income inequality was added and to 1.27 (95% CI = 1.10, 1.45) when state median income was included. The deleterious effect of low individual household income on self-rated health was most pronounced among states with the greatest voting and income inequality. Socioeconomic inequality in political participation (as measured by voter turnout) is associated with poor self-rated health, independently of both income inequality and state median household income.

    MONETARY INCENTIVES ARE INCREASINGLY used to help motivate survey participation. Research Ethics Committees have begun to ask whether, and under what conditions, the use of monetary incentives to induce participation might be coercive. The article reports research from an online vignette-based study bearing on this question, concluding that at present the evidence suggests that larger incentives do not induce research participants to accept higher risks than they would be unwilling to accept with smaller ones.

    2010-04-01

    Response rates to surveys are decreasing. The purpose of this study was to evaluate the use of lottery tickets as incentives in an epidemiologic control group. A self-administered questionnaire was sent to parents in the municipality of Stockholm, Sweden, who were to be used as a control group in a study addressing stress in parents of children with cancer. A stratified random sample of 450 parents were randomized into three incentive groups: (a) no incentive; (b) a promised incentive of one lottery ticket to be received upon reply; (c) a promised incentive of one lottery ticket to be received upon reply and an additional lottery ticket upon reply within 1 week. The overall response rate across the three groups was 65.3%. The response rate was highest in the no incentive group (69.3%) and lowest in the one plus one lottery ticket group (62.0%). In a survival analysis, the difference between the two response curves was significant by the log-rank test (P = 0.04), with the no incentive group having a shorter time to response than the incentive group. Our findings suggest that the use of lottery tickets as incentives to increase participation in a mail questionnaire among parents may be less valuable or even harmful. Incentives may undermine motivation in studies in which the intrinsic motivation of the respondents is already high.

    Batterham, Philip J

    2014-06-01

    Postal and telephone survey research is threatened by declining response rates and high cost. Online recruitment is becoming more popular, although there is little empirical evidence about its cost-effectiveness or the representativeness of online samples. There is also limited research on optimal strategies for developing advertising content for online recruitment. The present study aimed to assess these aspects of online recruitment. Two mental health surveys used advertisements within a social network website (Facebook) to recruit adult Australian participants. The initial survey used advertisements linking directly to an external survey website, and recruited 1283 participants at $9.82 per completed survey. A subsequent survey used advertisements linking to a Facebook page that featured links to the external survey, recruiting 610 participants at $1.51 per completion. Both surveys were more cost-effective than similar postal surveys conducted previously, which averaged $19.10 per completion. Online and postal surveys both had somewhat unrepresentative samples. However, online surveys tended to be more successful in recruiting hard-to-reach populations. Advertising using "problem" terminology was more effective than "positive" terminology, while there was no significant effect of altruistic versus self-gain terminology. Online recruitment is efficient, flexible and cost-effective, suggesting that online recruitment has considerable potential for specific research designs.

    Assessing the oral health of an ageing population: methods, challenges and predictors of survey participation Objectives To examine predictors of participation and to describe the methodological considerations of conducting a two-stage population-based oral health survey. Methods An observational, cross-sectional survey (telephone interview and clinical oral examination) of community-dwelling adults aged 45–64 and ≥65 living in Nova Scotia, Canada was conducted. Results The survey response rate was 21% for the interview and 13.5% for the examination. A total of 1141 participants completed one or both components of the survey. Both age groups had higher levels of education than the target population; the age 45–64 sample also had a higher proportion of females and lower levels of employment than the target population. Completers (participants who completed interview and examination) were compared with partial completers (who completed only the interview), and stepwise logistic regression was performed to examine predictors of completion. Identified predictors were as follows: not working, post-secondary education and frequent dental visits. Conclusion Recruitment, communications and logistics present challenges in conducting a province-wide survey. Identification of employment, education and dental visit frequency as predictors of survey participation provide insight into possible non-response bias and suggest potential for underestimation of oral disease prevalence in this and similar surveys. This potential must be considered in analysis and in future recruitment strategies. PMID:21916953

  18. Barriers to participation in a patient satisfaction survey: who are we missing?

    Directory of Open Access Journals (Sweden)

    Angèle Gayet-Ageron

    Full Text Available BACKGROUND: A common weakness of patient satisfaction surveys is a suboptimal participation rate. Some patients may be unable to participate, because of language barriers, physical limitations, or mental problems. As the role of these barriers is poorly understood, we aimed to identify patient characteristics that are associated with non-participation in a patient satisfaction survey. METHODOLOGY: At the University Hospitals of Geneva, Switzerland, a patient satisfaction survey is regularly conducted among all adult patients hospitalized for >24 hours on a one-month period in the departments of internal medicine, geriatrics, surgery, neurosciences, psychiatry, and gynaecology-obstetrics. In order to assess the factors associated with non-participation to the patient satisfaction survey, a case-control study was conducted among patients selected for the 2005 survey. Cases (non respondents, n = 195 and controls (respondents, n = 205 were randomly selected from the satisfaction survey, and information about potential barriers to participation was abstracted in a blinded fashion from the patients' medical and nursing charts. PRINCIPAL FINDINGS: Non-participation in the satisfaction survey was independently associated with the presence of a language barrier (odds ratio [OR] 4.53, 95% confidence interval [CI95%]: 2.14-9.59, substance abuse (OR 3.75, CI95%: 1.97-7.14, cognitive limitations (OR 3.72, CI95%: 1.64-8.42, a psychiatric diagnosis (OR 1.99, CI95%: 1.23-3.23 and a sight deficiency (OR 2.07, CI95%: 0.98-4.36. The odds ratio for non-participation increased gradually with the number of predictors. CONCLUSIONS: Five barriers to non-participation in a mail survey were identified. Gathering patient feedback through mailed surveys may lead to an under-representation of some patient subgroups.

    2013-01-01

    To survey participants at various experience levels of different martial arts (MA) about upper extremity injuries sustained during training and fighting. A 21-s question survey was designed and utilised. The survey was divided into four groups (Demographics, Injury Description, Injury Mechanism, and Miscellaneous information) to gain knowledge about upper extremity injuries sustained during martial arts participation. Chi-square testing was utilised to assess for significant associations. Males comprised 81% of respondents. Involvement in multiple forms of MA was the most prevalent (38%). The hand/wrist was the most common area injured (53%), followed by the shoulder/upper arm (27%) and the forearm/elbow (19%). Joint sprains/muscle strains were the most frequent injuries reported overall (47%), followed by abrasions/bruises (26%). Dislocations of the upper extremity were reported by 47% of participants while fractures occurred in 39%. Surgeries were required for 30% of participants. Females were less likely to require surgery and more likely to have shoulder and elbow injuries. Males were more likely to have hand injuries. Participants of Karate and Tae Kwon Do were more likely to have injuries to their hands, while participants of multiple forms were more likely to sustain injuries to their shoulders/upper arms and more likely to develop chronic upper extremity symptoms. With advanced level of training the likelihood of developing chronic upper extremity symptoms increases, and multiple surgeries were required. Hand protection was associated with a lower risk of hand injuries. Martial arts can be associated with substantial upper extremity injuries that may require surgery and extended time away from participation. Injuries may result in chronic upper extremity symptoms. Hand protection is important for reducing injuries to the hand and wrist.

    2014-01-01

    Population health surveys have been the main data source for analysis of immigrants' health status in Spain. The aim of this study was to analyze the representation of this population in the Spanish National Health Survey (SNHS) 2011-2012. We analyzed methodological publications and data from the SNHS 2011-2012 and the population registry. Differences in the participation rate between the national and foreign populations and the causes for these differences were analyzed, as well as the representation of 11 countries of birth in the survey with respect to the general population, with and without weighting. Households with any foreign person had a lower participation rate, either due to a higher error in the sampling frame or to a higher non-response rate. In each country of birth, the sample was smaller than would be expected according to the population registry, especially among the Chinese population. When we applied the sample weights to the 11 countries of birth, the estimated population volume was closer to the estimated volume of the population registry for all the countries considered, although globally both the underrepresentation and the intranational bias remained. The lower participation of the immigrant population and differences in participation depending on the country of origin suggest the existence of a potential bias in the SNHS, which should be taken into account in studies analyzing the health of this population. The lower participation rate should be studied in greater depth in order to take appropriate measures to increase the representativeness of health surveys. Copyright © 2014 SESPAS.

  2. Participation rate or informed choice? Rethinking the European key performance indicators for mammography screening.

    Science.gov (United States)

    Strech, Daniel

    2014-03-01

    Despite the intensive controversies about the likelihood of benefits and harms of mammography screening almost all experts conclude that the choice to screen or not to screen needs to be made by the individual patient who is adequately informed. However, the "European guideline for quality assurance in breast cancer screening and diagnosis" specifies a participation rate of 70% as the key performance indicator for mammography screening. This paper argues that neither the existing evidence on benefits and harms, nor survey research with women, nor compliance rates in clinical trials, nor cost-effectiveness ratios justify participation rates as a reasonable performance indicator for preference-sensitive condition such as mammography screening. In contrast, an informed choice rate would be more reasonable. Further research needs to address the practical challenges in assessing informed choice rates.

    Full Text Available Abstract Background ParticipACTION is a Canadian physical activity (PA communications and social marketing organization that was relaunched in 2007 after a six-year hiatus. This study assesses the baseline awareness and capacity of Canadian organizations that promote physical activity, to adopt, implement and promote ParticipACTION's physical activity campaign. The three objectives were: (1 to determine organizational awareness of both the 'original' and 'new' ParticipACTION; (2 to report baseline levels of three organizational capacity domains (i.e., to adopt, implement and externally promote physical activity initiatives; and, (3 to explore potential differences in those domains based on organizational size, sector and primary mandate. Methods Organizations at local, provincial/territorial, and national levels were sent an invitation via email prior to the official launch of ParticipACTION to complete an on-line survey. The survey assessed their organization's capacity to adopt, implement and externally promote a new physical activity campaign within their organizational mandates. Descriptive statistics were employed to address the first two study objectives. A series of one-way analysis of variance were conducted to examine the third objective. Results The response rate was 29.7% (268/902. The majority of responding organizations had over 40 employees and had operated for over 10 years. Education was the most common primary mandate, followed by sport and recreation. Organizations were evenly distributed between government and not-for-profits. Approximately 96% of respondents had heard of the 'original' ParticipACTION while 54.6% had heard of the 'new' ParticipACTION (Objective 1. Findings indicate good organizational capacity in Canada to promote physical activity (Objective 2 based on reported means of approximately 4.0 (on 5-point scales for capacity to adopt, implement, and externally promote new physical activity campaigns.

    Few studies have examined base rates of suboptimal effort among healthy, undergraduate students recruited for neuropsychological research. An and colleagues (2012, Conducting research with non-clinical healthy undergraduates: Does effort play a role in neuropsychological test performance? Archives of Clinical Neuropsychology, 27, 849-857) reported high rates of performance invalidity (30.8%-55.6%), calling into question the validity of findings generated from samples of college students. In contrast, subsequent studies have reported much lower base rates ranging from 2.6% to 12%. The present study replicated and extended previous work by examining the performance of 108 healthy undergraduates on the Dot Counting Test, Victoria Symptom Validity Test, Word Memory Test, and a brief battery of neuropsychological measures. During initial testing, 8.3% of the sample scored below cutoffs on at least one Performance Validity Test, while 3.7% were classified as invalid at Time 2 (M interval = 34.4 days). The present findings add to a growing number of studies that suggest performance invalidity base rates in samples of non-clinical, healthy college students are much lower than An and colleagues initial findings. Although suboptimal effort is much less problematic than suggested by An and colleagues, recent reports as high as 12% indicate including measures of effort may be of value when using college students as participants. Methodological issues and recommendations for future research are presented.

    Keightley, A; Clarkson, J; Maguire, A; Speed, C; Innes, N

    2014-11-01

    To identify reasons behind a lower than expected participant recruitment rate within the FiCTION trial, a multi-centre paediatric primary dental care randomised controlled trial (RCT). An online survey, based on a previously published tool, consisting of both quantitative and qualitative responses, completed by staff in dental practices recruiting to FiCTION. Ratings from quantitative responses were aggregated to give overall scores for factors related to participant recruitment. Qualitative responses were independently grouped into themes. Thirty-nine anonymous responses were received. Main facilitators related to the support received from the central research team and importance of the research question. The main barriers related to low child eligibility rates and the integration of trial processes within routine workloads. These findings have directed strategies for enhancing participant recruitment at existing practices and informed recruitment of further practices. The results help provide a profile of the features required of practices to successfully screen and recruit participants. Future trials in this setting should consider the level of interest in the research question within practices, and ensure trial processes are as streamlined as possible. Research teams should actively support practices with participant recruitment and maintain enthusiasm among the entire practice team.

    2002-03-01

    Full Text Available Abstract Background The loss of participants in longitudinal studies due to non-contact, refusal or death can introduce bias into the results of such studies. The study described here examines reasons for refusal over three waves of a survey of persons aged ≥ 70 years. Methods In a longitudinal study involving three waves, participants were compared to those who refused to participate but allowed an informant to be interviewed and to those who refused any participation. Results At Wave 1 both groups of Wave 2 non-participants had reported lower occupational status and fewer years of education, had achieved lower verbal IQ scores and cognitive performance scores and experienced some distress from the interview. Those with an informant interview only were in poorer physical health than those who participated and those who refused. Depression and anxiety symptoms were not associated with non-participation. Multivariate analyses found that verbal IQ and cognitive impairment predicted refusal. Results were very similar for refusers at both Waves 2 and 3. Conclusions Longitudinal studies of the elderly may over estimate cognitive performance because of the greater refusal rate of those with poorer performance. However, there is no evidence of bias with respect to anxiety or depression.

    2010-06-01

    Full Text Available Abstract Background Although indicated prevention of depression is available for about 80% of the Dutch population at little or no cost, only a small proportion of those with subthreshold depression make use of these services. Methods A narrative review is conducted of the Dutch preventive services in mental health care, also addressing the problem of low participation rates. We describe possible causes of these low participation rates, which may be related to the participants themselves, the service system, and the communication to the public, and we put forward possible solutions to this problem. Results There are three main groups of reasons why the participation rates are low: reasons within the participants (e.g., not considering themselves as being at risk; thinking the interventions are not effective; or being unwilling to participate because of the stigma associated with depression; reasons within the health care system; and reasons associated with the communication about the preventive services. Possible solutions to increasing the participation rate include organizing mass media campaigns, developing internet-based preventive interventions, adapting preventive interventions to the needs of specific subpopulations, positioning the services in primary care, integrating the interventions in community-wide interventions, and systematically screening high-risk groups for potential participants. Discussion Prevention could play an important role in public mental health in reducing the enormous burden of depression. However, before this can be realized more research is needed to explore why participation rates are low and how these rates can be improved.

    2016-09-01

    For a longitudinal prospective cohort study to be successful, participants' motivation to provide information must be maintained. Therefore, this study aimed to identify items that effectively promote participants' motivation. Questionnaires were mailed to 4541 mothers and expectant mothers in Chiba Prefecture, Japan who participated in a nationwide birth cohort. A total of 2387 (52.6%) responses were received. The following items were identified as primary motivating factors among our cohort: "benefits to the participants' children", "monetary compensation" and "contribution to a better future environment". More than 30% of the respondents expressed a lack of understanding regarding the study purpose and requirements for participation. About 14% were concerned about the leakage of personal information, and 13% felt burdened by having to make a long-term commitment to the study. Cluster analysis identified four groups, two of which, one with extremely low levels of motivation and the other motivated by only money or goods, lacked an understanding of the study and tended to be concerned about the associated risks and burdens. Participants in these groups were considered to be at a high risk of dropout. Therefore, implementing measures to provide participants with a better understanding of cohort studies could lead to more successful results.

    Louis Germaine M

    2010-05-01

    Full Text Available Abstract Background A considerable literature now supports the importance of effective communication with study participants, including how best to develop communication plans focusing on the uncertainty of health risks associated with particular environmental exposures. Strategies for communicating individual concentrations of environmental chemicals in human biological samples in the absence of clearly established safe or hazardous levels have been discussed from a conceptual basis and to a lesser extent from an empirical basis. We designed and evaluated an empirically based communication strategy for women of reproductive age who previously participated in a prospective study focusing on persistent environmental chemicals and reproductive outcomes. Methods A cohort of women followed from preconception through pregnancy or up to 12 menstrual cycles without pregnancy was given their individual serum concentrations for lead, dichloro-2,2-bisp-chlorophenyl ethylene, and select polychlorinated biphenyl congeners. Two versions of standardized letters were prepared depending upon women's exposure status, which was characterized as low or high. Letters included an introduction, individual concentrations, population reference values and guidance for minimizing future exposures. Participants were actively monitored for any questions or concerns following receipt of letters. Results Ninety-eight women were sent letters informing them of their individual concentrations to select study chemicals. None of the 89 (91% participating women irrespective of exposure status contacted the research team with questions or concerns about communicated exposures despite an invitation to do so. Conclusions Our findings suggest that study participants can be informed about their individual serum concentrations without generating unnecessary concern.

    Jacobsen, Christian Bøtcher; De Lorent Gad, Mette; Kjeldsen, Anne Mette

    The most widely used method to study individuals’ public service motivation is surveys. The validity and inferential power of such studies may, however, be harmed by survey participation bias, if highly public service motivated individuals are overrepresented among respondents. This paper examines...... the methodological critique of survey participation bias raised against the public service motivation literature and examines whether public service motivation increases the propensity to respond to surveys. By tracking more than 3,000 public service providers’ participation in a three-wave panel survey, our...... analysis shows that public service motivation does have a positive effect on survey participation. This suggests that future studies should pay attention to the characteristics of respondents/non-respondents and consider weighting the sample....

    The main advantages of online questionnaires are the speed of data collection and cost savings, but response rates are usually low. This study analyzed response rates and associated factors among health professionals in three opinion surveys in the autonomous region of Madrid. The participants, length of the questionnaire and topic differed among the three surveys. The surveys were conducted by using paid Internet software. The institutional e-mail addresses of distinct groups of health professionals were used. Response rates were highest in hospitals (up to 63%) and administrative services and were lowest in primary care (less than 33%). The differences in response rates were analyzed in primary care professionals according to age, sex and professional category and only the association with age was statistically significant. None of the surveys achieved a response rate of 60%. Differences were observed according to workplace, patterns of Internet usage, and interest in the subject. Copyright © 2011 SESPAS.

    The concept of aqueous computing is presented here, first in full generality,and afterward, using an implementation in a specific enzymatic technology. Aqueous computingarose in the context of biomolecular (DNA) computing, but the concept is independent ofthe specifics of its biochemical origin. Alternate technologies for realizing aqueous computingare being considered for future implementation. A solution of an instance of the Booleansatisfiability problem, (SAT), is reported here that provides a new example of an aqueouscomputation that has been carried out successfully. This small instance of the SAT problemis sufficiently complex to allow our current enzymatic technology to be illustrated in detail.The reader is invited to participate in the rich interdisciplinary activity required by wet labcomputing. A project is suggested to the reader for determining the three-colorings of a graph.The basic operations required for this project are exhibited in the solution of the SAT examplereported here.

    This study analysed the characteristics of respondent and nonrespondent mothers at each stage of a survey procedure, from a initial questionnaire to a reminder letter and two repeated mailings. Of 938 mothers of liveborn children who, while maternity inpatients, received a questionnaire and information about a mail survey to follow 2 months later, 828 completed and returned the initial questionnaire, 708 agreed to participate in the mail survey and were sent the mail questionnaire, and 612 finally completed and returned the questionnaire at 2 months. There were differences between respondents and non-respondents for socio-demographic factors at each stage of the process. The final response rate to the mail questionnaire was higher among mothers who were younger, were breast feeding, and had more education, an occupation and fewer children. The characteristics of late respondents were intermediate between those of early to middle respondents and nonrespondents for age, educational level, breast feeding and occupation. Maternal and infant health varied only slightly according to response status. Repeated mailings increased response and diminished selection. A mail questionnaire after contact in a maternity ward is a cost-effective means of gathering data about a large sample of recent mothers and their children.

    2016-01-01

    There is a gap between increasing demands from pharmacy journals, publishers, and reviewers for high survey response rates and the actual responses often obtained in the field by survey researchers. Presumably demands have been set high because response rates, times, and costs affect the validity and reliability of survey results. Explore the extent to which survey response rates, average response times, and economic costs are affected by conditions under which pharmacist workforce surveys are administered. A random sample of 7200 U.S. practicing pharmacists was selected. The sample was stratified by delivery method, questionnaire length, item placement, and gender of respondent for a total of 300 observations within each subgroup. A job satisfaction survey was administered during March-April 2012. Delivery method was the only classification showing significant differences in response rates and average response times. The postal mail procedure accounted for the highest response rates of completed surveys, but the email method exhibited the quickest turnaround. A hybrid approach, consisting of a combination of postal and electronic means, showed the least favorable results. Postal mail was 2.9 times more cost effective than the email approach and 4.6 times more cost effective than the hybrid approach. Researchers seeking to increase practicing pharmacists' survey participation and reduce response time and related costs can benefit from the analytical procedures tested here.

    2005-10-01

    We surveyed the attitudes of medical practitioners towards evidence-based medicine (EBM) and characterized those with an interest in participating in EBM courses. A random sample of 900 outpatient care doctors stratified by level and field of specialization was surveyed by means of a postal questionnaire. Importance of knowledge on information management, a positive attitude towards EBM and not yet doing critical appraisal were significant predictors of interest in participating in EBM courses. Low participation rates of outpatient care doctors in EBM courses are not due to attitudinal or general motivational problems. Although possible predictors of interest in participation could be specified, further factors contributing to actual participation need to be identified.

    Full Text Available The purpose of this paper is to test hysteresis of the Romanian labour force participation rate, by using time series data, with quarterly frequency, covering the period 1999Q1-2013Q4. The main results reveal that the Romanian labour force participation rate is a nonlinear process and has a partial unit root (i.e. it is stationary in the first regime and non-stationary in the second one, the main breaking point being registered around year 2005. In this context, the value of using unemployment rate as an indicator for capturing joblessness in this country is debatable. Starting from 2005, the participation rate has not followed long-term changes in unemployment rate, the disturbances having permanent effects on labour force participation rate.

    1994-01-01

    Many methods have been developed to aid analysts in identifying component modes which contribute significantly to component responses. These modes, typically targeted for dynamic model correlation via a modal survey, are known as target modes. Most methods used to identify target modes are based on component global dynamic behavior. It is sometimes unclear if these methods identify all modes contributing to responses important to the analyst. These responses are usually those in areas of hardware design concerns. One method used to check the completeness of target mode sets and identify modes contributing significantly to important component responses is mode participation. With this method, the participation of component modes in dynamic responses is quantified. Those modes which have high participation are likely modal survey target modes. Mode participation is most beneficial when it is used with responses from analyses simulating actual flight events. For spacecraft, these responses are generated via a structural dynamic coupled loads analysis. Using MSC/NASTRAN DMAP, a method has been developed for calculating mode participation based on transient coupled loads analysis results. The algorithm has been implemented to be compatible with an existing coupled loads methodology and has been used successfully to develop a set of modal survey target modes.

    Cheng, Joyce; Niles, Andrea N; Craske, Michelle G

    2017-03-01

    Individuals with public speaking anxiety (PSA) under-rate their performance compared to objective observers. The present study examined whether exposure reduces the discrepancy between self and observer performance ratings and improved observer-rated performance in individuals with PSA. PSA participants gave a speech in front of a small audience and rated their performance using a questionnaire before and after completing repeated exposures to public speaking. Non-anxious control participants gave a speech and completed the questionnaire one time only. Objective observers watched videos of the speeches and rated performance using the same questionnaire. PSA participants underrated their performance to a greater degree than did controls prior to exposure, but also performed significantly more poorly than did controls when rated objectively. Bias significantly decreased and objective-rated performance significantly increased following completion of exposure in PSA participants, and on one performance measure, anxious participants no longer showed a greater discrepancy between self and observer performance ratings compared to controls. The study employed non-clinical student sample, but the results should be replicated in clinical anxiety samples. These findings indicate that exposure alone significantly reduces negative performance bias among PSA individuals, but additional exposure or additional interventions may be necessary to fully correct bias and performance deficits.

    2010-12-01

    CoCoRaHS (The Community Collaborative Rain, Hail and Snow network) is based out of Fort Collins Colorado and is an extremely successful citizen science project with over 15,000 volunteers collecting valuable precipitation data. Forecasters and scientists use data from this dense network to illuminate and illustrate the high small-scale variability of precipitation across the nation. This presentation will discuss the results of a survey of CoCoRaHS participants as related to 1) citizen scientists’ motivation and learning; 2) the challenges of identifying how people learn science in citizen science projects; and 3) a potential research-based framework for how people learn through engaging in the data collection within in a citizen science project. A comprehensive survey of 14,500 CoCoRaHS observers was recently conducted to uncover participant perceptions of numerous aspects of the CoCoRaHS program, including its goal of increasing climate literacy. The survey yielded a response rate of over 50%, and included measures of motivation, engagement and learning. In relationship to motivation and learning, the survey revealed that most (57.1%) observers would make precipitation observations regardless of being a CoCoRaHS volunteer, therefore their motivation is related to their inherent level of interest in weather. Others are motivated by their desire to learn more about weather and climate, they want to contribute to a scientific project, they think its fun, and/or it provides a sense of community. Because so many respondents already had knowledge and interest in weather and climate, identifying how and what people learn through participating was a challenge. However, the narrow project focus of collecting and reporting of local precipitation assisted in identifying aspects of learning. For instance, most (46.4%) observers said they increased their knowledge about the local variability in precipitation even though they had been collecting precipitation data for many

    2011-01-01

    Full Text Available Abstract Background Randomised controlled trials have investigated aspects of postal survey design yet cannot elaborate on reasons behind participants' decision making and survey behaviour. This paper reports participants' perspectives of the design of, and participation in, a longitudinal postal cohort survey. It describes strengths and weaknesses in study design from the perspectives of study participants and aims to contribute to the: 1 design of future cohort surveys and questionnaires generally and, 2 design of cohort surveys for people with musculoskeletal disorders (MSDs specifically. Methods In-depth interviews explored the design of postal surveys previously completed by participants. Interviews used open ended questioning with a topic guide for prompts if areas of interest were not covered spontaneously. Thematic data analysis was undertaken based on the framework method. A second researcher verified all coding. Results Data from fourteen interviews were analysed within three main themes; participation, survey design and survey content. One of the main findings was the importance of clear communication aimed at the correct audience both when inviting potential participants to take part and within the survey itself. Providing enough information about the study, having a topic of interest and an explanation of likely benefits of the study were important when inviting people to participate. The neutrality of the survey and origination from a reputable source were both important; as was an explanation about why information was being collected within the survey itself. Study findings included participants' impressions when invited to take part, why they participated, the acceptability of follow-up of non-responders and why participants completed the follow-up postal survey. Also discussed were participants' first impression of the survey, its length, presentation and participants' views about specific questions within the survey

  7. Choice of rating scale labels: implication for minimizing patient satisfaction response ceiling effect in telemedicine surveys.

    Science.gov (United States)

    Masino, Caterina; Lam, Tony C M

    2014-12-01

    Lack of response variability is problematic in surveys because of its detrimental effects on sensitivity and consequently reliability of the responses. In satisfaction surveys, this problem is caused by the ceiling effect resulting from high satisfaction ratings. A potential solution strategy is to manipulate the labels of the rating scale to create greater discrimination of responses on the high end of the response continuum. This study examined the effects of a positive-centered scale on the distribution and reliability of telemedicine satisfaction responses in a highly positive respondent population. In total, 216 telemedicine participants were randomly assigned to one of three experimental conditions as defined by the form of Likert scale: (1) 5-point Balanced Equal-Interval, (2) 5-point Positive-Packed, and (3) 5-point Positive-Centered Equal-Interval. Although the study findings were not statistically significant, partially because of sample size, the distribution and internal consistency reliability of responses occurred in the direction hypothesized. Loading the rating scale with more positive labels appears to be a useful strategy for reducing the ceiling effect and increases the discrimination ability of survey responses. The current research provides a survey design strategy to minimize ceiling effects. Although the findings provide some evidence suggesting the benefit of using rating scales loaded with positive labels, more research is needed to confirm this, as well as extend it to examine other types of rating scales and the interaction between rating scale formats and respondent characteristics.

    Full Text Available Introduction   By the end of the 1950s, the number of people aged above 65 was 200 million worldwide. By the end of the last century, this population increased threefold to 590 million. By 2025, this aged population is estimated to rise to 1100 million. Generally, the increase in the rate of the world population is 1.7%, but the projected rate of increase of the aged population is 2.5% per year (German, 2002. Similarly, Iranian society will have an effective and operative group who are going to shape its communities and networks. Iran is developing into a crowded country with 75 million people. It has a rate of 2.8% increase in total elderly population compared to the National Fertility Rate of 1.2% (Iran Statistics & Census Centre or ISCC, 2007a. According to the ISCC, in 2007 people who were in their 60s and above formed 6.8% of the Iranian population with national rate of increase rate at 2.8% (ISCC, 1997, 2007c. Based on the civic law and judiciary system, the age of the elderly at the first year of retirement was defined above 60, which is five years less than WHO’s definition for old age. On the other hand, there has been some evidence of local and national references to such social problems as reduction in social participation, social trust, social relations and support, communal activity, civic engagement (CE, economic and social security, leisure activities, mobility, neighborhoods, and safe areas. Among other problems are decline in social indicators like societal networks, social cohesion and inclusion, civic engagement, social capital (SC, and increase of informal and familial solidarity which result in social exclusion (Dinie, 2007; Firouz Abadi & Imani Jajarmi, 2007; Ghaffari, 2001; Ghasemi, Esmaieli & Rabeie, 2007; Joshanlou & Qaedi, 2010; Joshanlou, Rostami, & Nosrat Abadi, 2007; Saadat, 2006a.

    Full Text Available Abstract Background Although systematic reviews of health care interventions are an invaluable tool for health care providers and researchers, many potential authors never publish reviews. This study attempts to determine why some people with interest in performing systematic reviews do not subsequently publish a review; and what steps could possibly increase review completion. Methods Cross-sectional survey by email and facsimile of the 179 participants in Australasian Cochrane Centre training events between 1998 and 2000. Results Ninety-two participants responded to the survey (51 percent. Response rate of deliverable surveys was 82 percent (92/112. The remainder of the participants had invalid or no contact information on file. More than 75 percent of respondents felt that the current workshops met their needs for training. The most critical barriers to completion of a Cochrane review were: lack of time (80 percent, lack of financial support (36 percent, methodological problems (23 percent and problems with group dynamics (10 percent. Conclusions Strategies to protect reviewer time and increase the efficiency of the review process may increase the numbers of trained reviewers completing a systematic review.

    Full Text Available Abstract Background There is an increasing trend towards lower participation in questionnaire surveys. This reduces representativeness, increases costs and introduces particular challenges to longitudinal surveys, as researchers have to use complex statistical techniques which attempt to address attrition. This paper describes a trial of incentives to retain longitudinal survey cohorts from ages 16 to 20, to question them on the sensitive topic of sexual health. Methods A longitudinal survey was conducted with 8,430 eligible pupils from two sequential year groups from 25 Scottish schools. Wave 1 (14 years and Wave 2 (16 years were conducted largely within schools. For Wave 3 (18 years, when everyone had left school, the sample was split into 4 groups that were balanced across predictors of survey participation: 1 no incentive; 2 chance of winning one of twenty-five vouchers worth £20; 3 chance of winning one £500 voucher; 4 a definite reward of a £10 voucher sent on receipt of their completed questionnaire. Outcomes were participation at Wave 3 and two years later at Wave 4. Analysis used logistic regression and adjusted for clustering at school level. Results The only condition that had a significant and beneficial impact for pupils was to offer a definite reward for participation (Group 4. Forty-one percent of Group 4 participated in Wave 3 versus 27% or less for Groups 1 to 3. At Wave 4, 35% of Group 4 took part versus 25% or less for the other groups. Similarly, 22% of Group 4 participated in all four Waves of the longitudinal study, whereas for the other three groups it was 16% or less that participated in full. Conclusions The best strategy for retaining all groups of pupils and one that improved retention at both age 18 and age 20 was to offer a definite reward for participation. This is expensive, however, given the many benefits of retaining a longitudinal sample, we recommend inclusion of this as a research cost for cohort and other

    Background As blended learning (BL; a combination of face-to-face and e-learning methods) becomes more commonplace, it is important to assess whether students find it useful for their studies. ARCADE HSSR and ARCADE RSDH (African Regional Capacity Development for Health Systems and Services Research; Asian Regional Capacity Development for Research on Social Determinants of Health) were unique capacity-building projects, focusing on developing BL in Africa and Asia on issues related to global health. Objective We aimed to evaluate the student experience of participating in any of five ARCADE BL courses implemented collaboratively at institutions from Africa, Asia, and Europe. Design A post-course student survey with 118 students was conducted. The data were collected using email or through an e-learning platform. Data were analysed with SAS, using bivariate and multiple logistic regression. We focused on the associations between various demographic and experience variables and student-reported overall perceptions of the courses. Results In total, 82 students responded to the survey. In bivariate logistic regression, the course a student took [p=0.0067, odds ratio (OR)=0.192; 95% confidence interval (CI): 0.058–0.633], male gender of student (p=0.0474, OR=0.255; 95% CI: 0.066–0.985), not experiencing technical problems (pstudent needs (p=0.0036, OR=0.165; 95% CI: 0.049–0.555) were found to be associated with a more positive perception of BL, as measured by student rating of the overall helpfulness of the e-learning component to their studies. In contrast, perceiving the assessment as adequate was associated with a worse perception of overall usefulness. In a multiple regression, the course, experiencing no technical problems, and perceiving the discussion as adequate remained significantly associated with a more positively rated perception of the usefulness of the online component of the blended courses. Discussion The results suggest that lack of technical

    Full Text Available BACKGROUND: A large trial to investigate the effectiveness of population based screening for chlamydia infections was conducted in the Netherlands in 2008-2012. The trial was register based and consisted of four rounds of screening of women and men in the age groups 16-29 years in three regions in the Netherlands. Data were collected on participation rates and positivity rates per round. A modeling study was conducted to project screening effects for various screening strategies into the future. METHODS AND FINDINGS: We used a stochastic network simulation model incorporating partnership formation and dissolution, aging and a sexual life course perspective. Trends in baseline rates of chlamydia testing and treatment were used to describe the epidemiological situation before the start of the screening program. Data on participation rates was used to describe screening uptake in rural and urban areas. Simulations were used to project the effectiveness of screening on chlamydia prevalence for a time period of 10 years. In addition, we tested alternative screening strategies, such as including only women, targeting different age groups, and biennial screening. Screening reduced prevalence by about 1% in the first two screening rounds and leveled off after that. Extrapolating observed participation rates into the future indicated very low participation in the long run. Alternative strategies only marginally changed the effectiveness of screening. Higher participation rates as originally foreseen in the program would have succeeded in reducing chlamydia prevalence to very low levels in the long run. CONCLUSIONS: Decreasing participation rates over time profoundly impact the effectiveness of population based screening for chlamydia infections. Using data from several consecutive rounds of screening in a simulation model enabled us to assess the future effectiveness of screening on prevalence. If participation rates cannot be kept at a sufficient level

    Obtaining the cooperation of citizens to participate in separate waste collection is essential to create a recycling-oriented society. In this research, the degree of change in the citizen participation rate, which occurs when the contents of political measures such as the raising of awareness, provision of information, and the conditions of collection services were changed, was estimated together with the effect on the reduction in environmental load. A questionnaire survey was conducted, targeted at residents of Itabashi Ward, while logistic regression analyses were also conducted to create predictive models for recycling behavior, and sensitivity analyses of the models were carried out to estimate the increase in citizen participation rate achievable through the implementation of various political measures. It was found that the effect of "thorough perception of information" was the largest, followed by "minimization of evaluation of trouble" and "thorough perception of efficacy of measures." The effect of the improvement in the citizen participation rate on the reduction in environmental load was also evaluated quantitatively by life cycle inventory analyses. It was indicated that "maximization of perception of information" had the greatest effect. However, the reduction effect with "paper packs" and "PET bottles" was relatively small compared with that of "bottles/cans."

    This study evaluated the predictive validity of the Survey of Readiness for Alcoholics Anonymous Participation (SYRAAP), which is a 15-item, self-administered instrument. Bivariate and multivariate analyses examined whether responses to the SYRAAP within 1 week of entering substance-use treatment (T1) were associated with posttreatment Alcoholics Anonymous (AA) participation at 3-month (T2) and 6-month (T3) follow-up assessments. The T1 assessment was completed by 268 respondents; the T2 and T3 assessments were completed by 232 (86%) and 217 (81%) respondents, respectively. Results revealed that responses to the SYRAAP at T1 predicted AA participation at T2 and T3. The findings indicate the SYRAAP is a valid measure for assessing readiness for participating in AA. Future research in relation to the SYRAAP and limitations of the current study are discussed.

    To determine continuing medical education (CME) course participants' use of social media (SM) and their attitudes about the value of SM for enhancing CME education and to examine associations between participants' characteristics and attitudes toward SM. We conducted a cross-sectional survey and validation study of 539 participants at a Mayo Clinic Internal Medicine CME course in November 2011. The Social Media Use and Perception Instrument (SMUPI) consisted of 10 items (5-point Likert scales) and categorical response options. The main outcome measures were psychometric characteristics of the SMUPI scale, course participants' use of SM, and their attitudes regarding the importance of SM for enhancing CME. Of 539 CME course participants, 327 (61%) responded to the SMUPI survey. Most respondents (291 [89%]) reported using SM, with the most common types being YouTube (189 of the 327 participants [58%]) and Facebook (163 of 327 [50%]). Factor analysis revealed a 2-dimensional assessment of course participants' attitudes. Internal consistency reliability (Cronbach α) was excellent for factor 1 (0.94), factor 2 (0.89), and overall (0.94). The CME course participants' favorable attitudes toward SM were associated with younger age (20-29 years, mean score 3.13; 30-39 years, 3.40; 40-49 years, 3.39; 50-59 years, 3.18; 60-69 years, 2.93; and ≥70 years, 2.92; P=.02), using SM frequently (never, mean score 2.49; less than once monthly, 2.75; once monthly, 3.21; weekly, 3.31; and daily, 3.81; PEducation and Research.

    Conducting patient-reported outcomes research with adolescents and young adults (AYAs) is difficult due to low participation rates and high attrition. Forty-seven AYAs with newly diagnosed cancer at two large hospitals were prospectively surveyed at the time of diagnosis and 3-6 and 12-18 months later. A subset participated in 1:1 semistructured interviews. Attrition prompted early study closure at one site. The majority of patients preferred paper-pencil to online surveys. Interview participants were more likely to complete surveys (e.g., 93% vs. 58% completion of 3-6 month surveys, P = 0.02). Engaging patients through qualitative methodologies and using patient-preferred instruments may optimize future research success.

    Full Text Available The aim of this paper is to contribute to the understanding of the behavior of participation rates in terms of gender differences. We employed smooth autoregressive transition models for the quarterly Turkish labor force participation rates (LFPR data between 2000: Q1 - 2011: Q4 to present an asymmetric participation behavior. The smoothness parameter indicates a gradual transition from low to high regimes. It is higher for female workers compared to the male workers. Participation rates diminish during a recession but they increase smoothly during the periods of expansion. The estimation results of Enders et al. (1998 also verified the asymmetry and nonlinearity in participation rates. During periods of economic expansion, they are higher than the threshold but the low regime indicator function takes the value zero. The results of the paper have economic implications for policy makers. Due to the discouraged worker and added worker effects, LFPR should be observed with the unemployment rates while evaluating the tightness of the labor market.

    VINCat is a nosocomial infection surveillance program in hospitals in Catalonia. The aim of the study was to determine the surveillance and control measures of methicillin-resistant Staphylococcus aureus (MRSA) in these centres. An e-mail survey was carried out from January to March 2013 with questions related to the characteristics of the hospitals and their control measures for MRSA. A response was received from 53 hospitals (>500 beds: 7; 200-500 beds: 14;<200 beds: 32; had ICU: 29). Computer alert of readmissions was available in 63%. There was active surveillance of patients admitted from another hospital (46.2%) or a long-term-care centre (55.8%), both being significantly more common measures in hospitals with a rate of MRSA≤22% (global median). Compliance with hand hygiene was observed in 77.4% of the centres, and was greater than 50% in 69.7% of them. All hospitals had contact precautions, although 62.3% did not have exclusive frequently used clinical material in bedrooms. The room cleaning was performed more frequently in 54.7% of hospitals, and 67.9% of them had programs for the appropriate use of antibiotics. This study provides information on the implementation of measures to prevent MRSA in hospitals participating in the VINCat program. Most of the centres have an MRSA protocol, however compliance with it should be improved, especially in areas such as active detection on admission in patients at risk, hand hygiene adherence, cleaning frequency and optimising the use of antibiotics.

    This article examines domestic violence among women who participate in microfinance in Bangladesh. Secondary analysis of survey data from nationally representative Bangladesh Demographic and Health Survey was used to investigate the association between microfinance participation and domestic violence of 4,163 ever-married women between the ages of 18 and 49 years. Outcome measure is experience of domestic violence as measured by a modified Conflict Tactics Scale (CTS) and predictor variables include microfinance, binary indicator of relatively better economic status, autonomy, decision-making power, and demographic variables. The likelihood of experiencing domestic violence was not found to vary with microfinance participation. However, the interaction effect of microfinance and better economic status was found to be significantly associated with domestic violence (9% increased probability). Experience of domestic violence was negatively associated with older age, higher education of the husband, and autonomy. In Bangladesh, microfinance participation may be associated with a higher probability of experiencing domestic violence for women with relatively better economic status, but not for the poorest of the poor.

  1. Modeling participation duration, with application to the North American Breeding Bird Survey

    We consider “participation histories,” binary sequences consisting of alternating finite sequences of 1s and 0s, ending with an infinite sequence of 0s. Our work is motivated by a study of observer tenure in the North American Breeding Bird Survey (BBS). In our analysis, j indexes an observer’s years of service and Xj is an indicator of participation in the survey; 0s interspersed among 1s correspond to years when observers did not participate, but subsequently returned to service. Of interest is the observer’s duration D = max {j: Xj = 1}. Because observed records X = (X1, X2,..., Xn)1 are of finite length, all that we can directly infer about duration is that D ⩾ max {j ⩽n: Xj = 1}; model-based analysis is required for inference about D. We propose models in which lengths of 0s and 1s sequences have distributions determined by the index j at which they begin; 0s sequences are infinite with positive probability, an estimable parameter. We found that BBS observers’ lengths of service vary greatly, with 25.3% participating for only a single year, 49.5% serving for 4 or fewer years, and an average duration of 8.7 years, producing an average of 7.7 counts.

    The purpose of this mixed methods study was to identify participants' attributions for their global impression of change ratings in a behavioral intervention for unexplained chronic fatigue and chronic fatigue syndrome. At 3-month follow-up, participants (N = 67) were asked "Why do you think you are (improved, unchanged, worse)?" Improved patients pointed to specific behavioral changes, unchanged patients referred to a lack of change in lifestyle, and worsened patients invoked stress and/or specific life events. Identifying patient perceptions of behaviors associated with patient global impression of change-rated improvement and non-improvement may assist in developing more effective management strategies in clinical care.

    To summarize previously published findings and to present the opinions of a group of reconstructive orthopedic surgeons from a single institution on participation in sports after hip or knee arthroplasty. We reviewed the literature pertaining to participation in sports after hip or knee arthroplasty and surveyed a group of orthopedic surgeons about their recommendations for resumption of various sports activities by patients who had undergone total hip or knee arthroplasty. A computerized literature search was performed, and salient issues about participation in sports after joint replacement procedures were synthesized. At the Mayo Clinic, 28 orthopedic surgeons (13 consultants and 15 fellows or residents) completed a single-page questionnaire that requested a recommendation ("yes," "no," or "depends") about patients resuming participation in 28 common sports after recovery from total hip or knee arthroplasty. Staff surgeon responses were compared with responses from fellows and residents by using the Mann-Whitney U test. Sports in which 75% of surgeons would not allow participation were identified as "not recommended," whereas sports in which 75% of surgeons would allow participation were labeled as "recommended." Fellows and residents were less likely than staff surgeons to allow return to cross-country skiing after total knee arthroplasty. Otherwise, responses from consultant surgeons and from fellows and residents did not differ significantly. Recommended sports included sailing, swimming laps, scuba diving, cycling, golfing, and bowling after hip and knee replacement procedures and also cross-country skiing after knee arthroplasty. Sports not recommended after hip or knee arthroplasty were running, waterskiing, football, baseball, basketball, hockey, handball, karate, soccer, and racquetball. After hip or knee arthroplasty, participation in no-impact or low-impact sports can be encouraged, but participation in high-impact sports should be prohibited.

    The treatment of cancer pain requires an individually-targeted multidimensional team approach. Further, the basic act for the Anti-Cancer Measures describes that medical staff including pharmacists should participate in the palliative care. Thus it is obvious that community pharmacists should also participate in palliative home care. In addition, a misunderstanding about opioids remains strong in Japan, which could be one of the barriers to palliative home care. In our previous report, we clarified for local residents the importance of educational activity using opioids as a new role for community pharmacists, and it was recognized of great significance by these pharmacists. In this study, we conducted a questionnaire survey among medical doctors, nurses, care managers and home helpers about the need and meaning of the educational activity performed by pharmacists in palliative home care. 86.4% of respondents felt pharmacists' participation in home care was required. Furthermore, most respondents thought that misunderstanding remained about opioids in palliative home care, and believed that pharmacists could play an important role in educational activity about opioids as experts in medicine. This study clarified that other medical team members need the participation of community pharmacists in palliative home care. Therefore, it seems important for these pharmacists to be proactive in participating in such care in the future.

    We examined the relationship between self-rated health and use of parks and recreation program participation by using logistic regression to analyze data from representative national surveys conducted in 1991 and 2015. Neither park use nor program participation were significantly related to self-rated health in 1991; however, both were significantly related in 2015. The growing relationship between use of parks and recreation programs and self-rated health during this period is likely the result of broad national health promotion efforts and provides support for funding of capital and operational expenses for park and recreation services.

    We use three years of data from the Supernova Legacy Survey (SNLS) to study the general properties of core-collapse and type Ia supernovae. This is the first such study using the "rolling search" technique which guarantees well-sampled SNLS light curves and good efficiency for supernovae brighter than $i^\\prime\\sim24$. Using host photometric redshifts, we measure the supernova absolute magnitude distribution down to luminosities $4.5 {\\rm mag}$ fainter than normal SNIa. Using spectroscopy and light-curve fitting to discriminate against SNIa, we find a sample of 117 core-collapse supernova candidates with redshifts $z<0.4$ (median redshift of 0.29) and measure their rate to be larger than the type Ia supernova rate by a factor $4.5\\pm0.8(stat.) \\pm0.6 (sys.)$. This corresponds to a core-collapse rate at $z=0.3$ of $[1.42\\pm 0.3(stat.) \\pm0.3(sys.)]\\times10^{-4}\\yr^{-1}(h_{70}^{-1}\\Mpc)^{-3}$.

    Full Text Available Abstract Background Response rates in surveys have been falling over the last 20 years, leading to the need for novel approaches to enhance recruitment. This study describes strategies used to maximise recruitment to a home interview survey of mothers with young children living in areas of high deprivation. Methods Mothers of two year old children received a letter from their GP inviting them to take part in a survey on diet. Participants were subsequently recruited by a researcher. The researcher first tried to contact potential participants by telephone, to discuss the study and make an appointment to conduct a home interview. Where telephone numbers for women could not be obtained from GP records, web searches of publicly available databases were conducted. After obtaining correct telephone numbers, up to six attempts were made to establish contact by telephone. If this was unsuccessful, a postal request for telephone contact was made. Where no telephone contact was achieved, the researcher sent up to two appointments by post to conduct a home interview. Results Participating GPs invited 372 women to take part in a home based interview study. GP practices provided telephone numbers for 162 women, of which 134 were valid numbers. The researcher identified a further 187 numbers from electronic directories. Further searches of GP records by practice staff yielded another 38 telephone numbers. Thus, telephone numbers were obtained for 99% of potential participants. The recruitment rate from telephone contacts was 77%. Most of the gain was achieved within four calls. For the remaining women, contact by post and home visits resulted in 18 further interviews, corresponding to 35% of the women not recruited by telephone. The final interview rate was 82%. This was possible because personal contact was established with 95% of potential participants. Conclusion This study achieved a high response rate in a hard to reach group. This was mainly achieved

    Little is known about the risks of injury to dogs participating in the relatively new sport of canine agility. The purpose of this study was to identify the factors that put the participating dog at risk as well as determine the anatomical sites that were most commonly injured. A retrospective survey using a paper and web-based data collection instrument was used to evaluate dogs participating in the sport of canine agility. Of the 1627 dogs included in the study, 33% were injured, and of those 58% were injured in competition. Most injuries occurred on dry outdoor surfaces. Border Collies were the most commonly injured, and injuries were in excess of what would be expected from their exposure. For all dogs, soft tissue injuries were most common. The shoulders and backs of dogs were most commonly injured. Dogs were most commonly injured by contact with an obstacle. The A-frame, dogwalk and bar jump obstacles were responsible for nearly two-thirds of injuries that resulted from contact with the obstacle. Border Collies are at higher risk for injury than would be expected from their exposure. The A-frame, dogwalk and bar jump obstacles put the shoulders and backs of dogs at risk. For the first time, this study gives us insight into injuries occurring in dogs participating in canine agility. This will help direct prospective studies that evaluate the safety of individual obstacles, direct rule changes and enable practitioners to understand the risks of the sport.

  13. Participation Rate as A Basis for Measuring Food Security Status of Meat

    Full Text Available Food security has been developed as way for decision makers to pay more attention to this sector. It is believed that foods which are efficiently produced in one area or country may be accessed by other areas or countries. However, this concept is difficult to be implemented since almost none of countries in the world have all resources to produce what is needed by its people. Food consumption, including beef, would be better measured using participation rate which indicates a cluster of its consumer instead of using all population as a denominator for calculating per capita consumption, except for commodities whose consumer member of its cluster close to 100% of the population. For commodities whose consumers less than 50% of its cluster it is more effective to use the size of the cluster as the denominator. Diversified food consumption of animal origin in Indonesia has been indicated by the fact that it has been naturally established. Animal meat consumption diversification for many reasons is influenced by cultural, preferences or other economic status of the households. This phenomena is also indicated by the magnitude of positive cross price elasticity between beef and mutton, beef and poultry meat, and between poultry meat and fish. Therefore, every effort to push higher consumption of one meat type, will reduce the participation rate of others. Susenas data indicated participation rates for beef and buffalo meat were 26.15% (2002, 21.93% (2005, 16.18% (2008 and 16.16% (2011, while poultry meat had higher participation rate as 65.46% (2002, 63.48% (2005, 57.67% (2008 and 56.98% (2011. Application of participation rate approach on the production of beef and buffalo meat resulted in the annual percapita consumption of 6.71 kg (2002, 10.47 kg (2005, 10.82 kg (2008 and 13.11 kg (2011. It concludes that balanced participation rates of meat components (beef and poultry meat, need to be maintained as the existed diversified meat consumption

    2006-12-01

    This article presents 5 studies related to the development and initial evaluation of the Survey of Readiness for Alcoholics Anonymous Participation (SYRAAP). The SYRAAP is a brief, multidimensional, self-administered instrument that assesses beliefs associated with Alcoholics Anonymous (AA) participation. Study 1 generated 239 candidate items for potential inclusion in the instrument. Study 2 assessed the content validity of these items according to 3 criteria and identified a subset of 60 with the highest values on the criteria for further consideration. Study 3 produced a shorter version of the SYRAAP and evaluated its structure, internal reliability, and validity. Study 4 reevaluated the structure and internal reliability of the SYRAAP and yielded findings that were generally consistent with those from Study 3. Study 5 established stability reliability for the instrument. The collective findings indicated the SYRAAP can reliably and validly assess individual-level beliefs associated with AA participation. The potential use of the SYRAAP for researchers and clinicians, along with limitations of the work presented here, are discussed. (c) 2006 APA, all rights reserved

    近年来中国劳动力市场上人力资本回报率不断提高,表明就业培训是继学历教育后提高人力资本的重要方式。将外来市民和农民工两群体进行对比,并从机会、结果和效率几个方面探讨,可以发现培训中存在的问题和改进方向。根据有较好代表性的北京调查数据,农民工参加培训的机会低于外来市民但收益非常显著,外来市民培训参与率更高但收益不显著。企业培训的选择性造成培训资源的配置存在一定问题,需要引入更多机制增加对农民工的培训。%Recently, studies show the rate of return on human capital in China's labor market keeps rising. Employment training is an essential method to improve human capital after school education. It is important for discovering problems and providing appropriate policy advice by comparing urban and rural migrants from the aspects of opportunity, result and efficiency of training. Using a set of survey data in Beijing, it is found that rural migrants have fewer opportunities but higher return, while urban migrants have more opportunities but no significant return. The selectivity of company training hinders its efficiency. More mechanisms and organizations are needed to enhance training for rural migrants and further improve their working conditions and incomes.

    2015-01-01

    The Committee on the Participation of Women in the SDSS (CPWS) was formed by the SDSS to evaluate the gender climate within the collaboration. The CPWS seeks to foster gender balance in our collaboration by fielding concerns from our members and by recommending best practices for establishing the SDSS leadership team. An important aspect of the mission of the CPWS is to regularly assess gender diversity and inclusiveness within the SDSS. Against the backdrop of the transition from SDSS-III to SDSS-IV, the CPWS has been collecting data relevant to gender issues through interviews and surveys. In April, 2014, the CPWS surveyed 251 SDSS-IV members (~50% of active membership) regarding gender and leadership. Broad findings from this survey include that the male-to-female ratio in SDSS-IV is about 3:1 and that the male-to-female ratio among those that identify themselves as being in an SDSS-IV leadership role is also close to 3:1. About 35% of those surveyed self-identify as an SDSS-IV "leader," though we recognize the possibility that active stakeholders might be more likely to respond to a demographics survey. About 80% of those that self-identify as leaders consider their leadership role within SDSS-IV to be officially acknowledged, regardless of gender. The fraction of women in SDSS leadership roles appears to be a weak function of current job position in that 6 of 32 (19%) senior faculty that are SDSS leaders are women, compared to 4 of 13 (31%) postdocs. Similarly, the fraction of SDSS leaders who are women is highest (32%) amongst those leaders who received their PhDs 6-10 years ago, while the fraction of female leaders amongst other age demographics is somewhat lower (20%). Although these are small sample sizes, this hints at a trend where women are most likely to fill SDSS leadership roles at certain stages of their lives and careers. The CPWS intends to use this initial survey data to establish a baseline for tracking SDSS-IV demographics, and thus hopes to

    The Baby-Friendly Hospital Initiative was launched by the World Health Organization and UNICEF in 1989 to promote, protect, and support breastfeeding worldwide. The objective of this study was to report breastfeeding rates and adherence to the Baby Friendly Hospital Initiative of the World Health Organization and UNICEF in Canada, as reported by participants in the Maternity Experiences Survey of the Canadian Perinatal Surveillance System. Eligible women (n = 8,244) were identified from a randomly selected sample of infants born 3 months before the May 2006 Canadian Census, and stratified by province or territory. Birth mothers living with their infants at the time of interview were invited to participate in a computer-assisted telephone interview conducted by Statistics Canada on behalf of the Public Health Agency of Canada. Interviews took approximately 45 minutes and were completed when infants were between 5 and 10 months old (between 9 and 14 months in the territories). Completed responses were obtained from 6,421 women (78% response rate). Nineteen of 309 questions concerned early mother-infant contact and breastfeeding practices. Breastfeeding intention (90.0%) and initiation (90.3%) rates were high, although exclusive breastfeeding rates at 6 months after birth (14.4%) were lower than desirable. The findings suggested a low adherence to several best practices advocated by the Baby-Friendly Hospital Initiative. Although breastfeeding initiation rates were relatively high in Canada, exclusive breastfeeding duration fell short of globally recommended standards.

    2014-10-01

    Using data from the 1999 and 2002 National Survey of America's Families, a large-scale nationally representative sample, this study finds that parental religious attendance is positively associated with parent self-rated health, parent mental well-being, positive parenting attitudes, child health, and child school engagement. Although the strength of these associations varies to some extent according to socio-demographic factors, the interactive patterns are not consistently predictable. Moreover, parental health and well-being and positive attitudes toward parenting appear to be important pathways linking parental religious attendance to child well-being. These findings suggest that opportunities for participation in local religious services offered by faith-based organizations may be fruitful avenues through which the government and society can help American families enhance parent and child well-being.

  7. Increasing homework completion and accuracy rates with parental participation for young children with Autism Spectrum Disorder

    Full Text Available Students with Autism Spectrum Disorder often experience difficulty completing homework assignments independently more than students without disabilities. This study examined the use of a daily report card while adding a parent teacher component on the homework completion and accuracy rates of two second grade boys diagnosed with Autism. Parental participation for graphing and reviewing the student data involved the home environment. Researchers found that the use of the daily report card for homework completion and accuracy increased student success with the added parent teacher communication component. The parent teacher intervention increased both students’ homework completion by 65% and 38% respectively and accuracy rates by 123% and 30% respectively compared, to baseline sessions. Data showed that the addition of a parent teacher graphing component can be effective with a daily report card to increase parental involvement, while also helping increase homework completion and accuracy rates in students with Autism.

    General population health examination surveys (HESs) provide a reliable source of information to monitor the health of populations. A number of countries across Europe are currently planning their first HES, or the first after a significant gap, and some of these intend offering appointments only during office hours and/or weekdays, raising concerns about representativeness of survey participants. It is important to ascertain whether personal characteristics of participants vary by time of day and day of week of data collection, in order to determine the association between time and day of interview and physical examination on the results of data collected in HES. Multivariable regression models were applied to national HES in England to examine socio-demographic and health variations in three combined day-time periods of interview and physical examination: weekday daytime; weekday evening; and weekend. The characteristics of participants interviewed or visited by a nurse varied by both time of day and day of the week for age, ethnicity, marital status, income, socio-economic group, economic activity and deprivation. People seen during weekday working hours had higher rates of poor self-reported health, limiting longstanding illness and obesity, and higher alcohol consumption, BMI and systolic blood pressure; adjustment for socio-demographic characteristics eliminated or substantially reduced these differences. People responsible for planning surveys should be aware of participant preference for the timing of data collection and ensure flexibility and choice in times and days offered to optimise participation rates and representativeness.

    Comorbidity at the time of diagnosis is an independent prognostic factor for survival among women suffering from cervical or breast cancer. Although cancer screening practices have proven their efficacy for mortality reduction, little is known about adherence to screening recommendations for women suffering from chronic conditions. We investigated the association between eleven chronic conditions and adherence to cervical and breast cancer screening recommendations in France. Using data from a cross-sectional national health survey conducted in 2008, we analyzed screening participation taking into account self-reported: inflammatory systemic disease, cancer, cardiovascular disease, chronic respiratory disease, depression, diabetes, dyslipidemia, hypertension, obesity, osteoarthritis and thyroid disorders. We first computed age-standardized screening rates among women who reported each condition. We then estimated the effect of having reported each condition on adherence to screening recommendations in logistic regression models, with adjustment for sociodemographic characteristics, socioeconomic position, health behaviours, healthcare access and healthcare use. Finally, we investigated the association between chronic conditions and opportunistic versus organized breast cancer screening using multinomial logistic regression. The analyses were conducted among 4226 women for cervical cancer screening and 2056 women for breast cancer screening. Most conditions studied were not associated with screening participation. Adherence to cervical cancer screening recommendations was higher for cancer survivors (OR = 1.73 [0.98-3.05]) and lower for obese women (OR = 0.73 [0.57-0.93]), when accounting for our complete range of screening determinants. Women reporting chronic respiratory disease or diabetes participated less in cervical cancer screening, except when adjusting for socioeconomic characteristics. Adherence to breast cancer screening recommendations was lower for

    Full Text Available Aims: Here, we present results from a prospective pilot study that was aimed at surveying changes in daily cigarette consumption in smokers making their first purchase at vape shops. Modifications in products purchase were also noted. Design: Participants were instructed how to charge, fill, activate and use their e-cigarettes (e-cigs. Participants were encouraged to use these products in the anticipation of reducing the number of cig/day smoked. Settings: Staff from LIAF contacted 10 vape shops in the province of the city of Catania (Italy that acted as sponsors to the 2013 No Tobacco Day. Participants: 71 adult smokers (≥18 years old making their first purchase at local participating vape shops were asked by professional retail staff to complete a form. Measurements: Their cigarette consumption was followed-up prospectively at 6 and 12 months. Details of products purchase (i.e., e-cigs hardware, e-liquid nicotine strengths and flavours were also noted. Findings: Retention rate was elevated, with 69% of participants attending their final follow-up visit. At 12 month, 40.8% subjects could be classified as quitters, 25.4% as reducers and 33.8% as failures. Switching from standard refillables (initial choice to more advanced devices (MODs was observed in this study (from 8.5% at baseline to 18.4% at 12 month as well as a trend in decreasing thee-liquid nicotine strength, with more participants adopting low nicotine strength (from 49.3% at baseline to 57.1% at 12 month. Conclusions: We have found that smokers purchasing e-cigarettes from vape shops with professional advice and support can achieve high success rates.

    2017-05-01

    Members of the public in England were invited in 2010 to take part in a national metals survey, by collecting samples of littoral sediment from a standing water body for geochemical analysis. To our knowledge, this is the first national sediment metals survey using public participation and reveals a snapshot of the extent of metals contamination in ponds and lakes across England. Hg, Ni, Cu, Zn and Pb concentrations exceeding sediment quality guidelines for the health of aquatic biota are ubiquitous in ponds and lakes, not just in areas with a legacy of industrial activity. To validate the public sampling approach, a calibration exercise was conducted at ten water bodies selected to represent a range of lakes found across England. Sediment concentrations of Hg, Ni, Cu, Zn and Pb were measured in samples of soil, stream and littoral and deep water sediment to assess inputs. Significant differences between littoral sediment metal concentrations occur due to local variability, but also organic content, especially in upland, peat soil catchments. Variability of metal concentrations between littoral samples is shown to be low in small (metal contamination in standing waters. However, the heterogeneity of geology, soils and history/extent of metal contamination in the English landscape, combined with the random nature of sample collection, shows that systematic sampling for evaluating the full extent of metal contamination in lakes is still required.

  14. Primitive running: a survey analysis of runners' interest, participation, and implementation.

    2012-08-01

    Running is a sport that has continued to see growth in numbers over the years. Recently, there has been a movement promoting running barefoot and in light, "minimalist" shoes. Advocates of barefoot running believe that a more primitive style of running may result in fewer running-related injuries and even possibly improve performance. To identify the current interest level and participation in barefoot or minimalist shod running, an electronic survey was developed and dispersed to 6,082 runners. The survey instrument examined demographics, motivating factors, used resources, perceived barriers, and expectations in runners who add barefoot or in minimalist shod running to their training. Seven hundred eighty-five (13%) runners completed the survey. Six hundred and thirty (75.7%) indicated they were at least somewhat interested in running barefoot or in minimalist shoes. One hundred seventy-two (21.9%) runners had previously tried barefoot running, whereas 239 (30.4%) had previously tried minimalist shoes. The primary motivating factor for those running barefoot or in minimalist shoes (n = 283) was to prevent future injury (n = 97, 34.3%). Advice from friends (n = 68, 24.5%) or books (n = 68, 24.5%) was the most commonly used resource in transitioning to barefoot or minimalist shod running. Fear of possible injury (n = 424, 54%) was the most prevalent perceived barrier in transitioning to barefoot or minimalist shod running. An overwhelming 671 (85.5%) indicated that they were at least somewhat likely to continue with or to add barefoot or minimalist shod running if provided sufficient instruction. Runners who are men, of younger age, and who consider themselves elite runners are somewhat more likely to be interested in barefoot or minimalist shod running.

  15. Person-fit statistics, response sets and survey participation in a population-based cohort study

    2015-01-01

    Full Text Available Person-fit methodology is a promising technique for identifying subjects whose test scores have questionable validity. Less is known however about this technique’s ability to predict survey participation longitudinally. This study presents theory-derived expectations related to social desirability, the tendency for extreme responding and traitedness for specific deviating answer patterns and an expected consistence of person-fit scores across 27 personality scales. Data from 5,114 subjects (Amelang, 1997 were reanalysed with a polytomous-Rasch model to estimate scale scores and von Davier and Molenaar’s (2003 person-fit statistics. The person-fit statistics of the 27 scales were examined together with the 27 person parameter scores in one common factor analysis. The person-fit scores served as indicators of the latent factor ‘scalability’ while the person-parameter scores were considered to index the bias introduced by social desirability. The sign of factor loadings showed consistency and validity of the tendency for social desirability and extreme responding. Moreover, the personfit- based subject classification derived from the baseline data was able to predict subjects’ participation at a 8,5-year follow-up. However, the nature of those associations was contrary to our predictions. The discussion addresses explanations and practical implications, but also the limitations pertaining to the identification and interpretation of person-fit scores.

    Consumers of mental health services have an important role to play in the higher education of nursing students, by facilitating understanding of the experience of mental illness and instilling a culture of consumer participation. Yet the level of consumer participation in mental health nursing programmes in Australia is not known. The aim of the present study was to scope the level and nature of involvement of consumers in mental health nursing higher education in Australia. A cross-sectional study was undertaken involving an internet survey of nurse academics who coordinate mental health nursing programmes in universities across Australia, representing 32 universities. Seventy-eight percent of preregistration and 75% of post-registration programmes report involving consumers. Programmes most commonly had one consumer (25%) and up to five. Face-to-face teaching, curriculum development, and membership-to-programme committees were the most regular types of involvement. The content was generally codeveloped by consumers and nurse academics (67.5%). The frequency of consumer involvement in the education of nursing students in Australia is surprisingly high. However, involvement is noticeably variable across types of activity (e.g. curriculum development, assessment), and tends to be minimal and ad hoc. Future research is required into the drivers of increased consumer involvement.

    Evaluations of school-based interventions and prevention programs typically require parental consent for students to participate. In school-based efforts, program evaluators may have limited access to parents and considerable effort is required to obtain signed consent. This issue is particularly salient when conducting research in under-resourced, urban schools, where parent involvement in the school setting may be somewhat limited. The aims of this article were to (a) examine the published school-based prevention and intervention literature to assess the state of the field in terms of consent procedures and participation rates; and (b) describe two examples of health promotion studies that used multi-component, partnership-based strategies in urban schools to encourage communication among children, their parents, and researchers. The purpose of the case studies was to generate hypotheses to advance the science related to school-based participant recruitment for research studies. Of nearly 500 studies reviewed, only 11.5% reported both consent procedures and participation rates. Studies using active consent procedures had a mean participation rate of 65.5% (range: 11-100%). This article highlights the need for researchers to report consent procedures and participation rates and describes partnership-based strategies used to enroll students into two urban, school-based health promotion studies.

    Despite the nation's rising epidemic of childhood obesity and diabetes, schools struggle to promote physical activities that help reduce risks for cardiovascular disease. Emerging data suggest that adopting novel activities into physical education (PE) curriculum may serve as an effective strategy for increasing physical activity in children. The purpose of this investigation was to characterize activity in the water and heart rates (HRs) of high school students participating in surf PE courses. Twenty-four male (n = 20) and female (n = 4) high school students (mean age = 16.7 ± 1.0 years) who were enrolled in surf PE courses at 2 high schools participated in this investigation. Daily measurements of surfing durations, average HR, and maximum HR were made on the students with HR monitors (PolarFT1) over an 8-week period. In addition, HR and activity in the water was evaluated during a single session in a subset of students (n = 11) using a HR monitor (PolarRCX5) and a video camera (Canon HD). Activity and HR were synchronized and evaluated in 5-second intervals during data analyses. The average duration that PE students participated in surfing during class was 61.7 ± 1.0 minutes. Stationary, paddling, wave riding, and miscellaneous activities comprised 42.7 ± 9.5, 36.7 ± 7.9, 2.9 ± 1.4, and 17.8 ± 11.4 percent of the surf session, respectively. The average and maximum HRs during these activities were 131.1 ± 0.9 and 177.2 ± 1.0 b·min, respectively. These data suggest that high school students participating in surf PE attained HRs and durations that are consistent with recommendations with cardiovascular fitness and health. In the future, PE programs should consider incorporating other action sports into their curriculum to enhance cardiovascular health.

    Little is known about the risk factors of proteinuria in the Asian population. On the basis of the association between rice intake patterns and chronic diseases, we hypothesized that rice intake patterns are associated with proteinuria in the Asian population. Data, including data regarding rice intake frequency and dipstick urinalysis results, from the Korea National Health and Nutrition Examination Survey in 1998, 2001, 2005, and 2007 were analyzed. The study involved 19,824 participants who were older than 20 years of age. Low rice intake was defined as consumption of rice ≤ 1 time/day. Proteinuria was defined as dipstick urinalysis protein ≥ 1 positive. Among the 19,824 participants, the prevalence of low rice intake and proteinuria were 17.3% and 2.9%, respectively. The low rice intake group showed a higher rate of proteinuria than the non-low rice intake group did (3.8% vs. 2.7%, P proteinuria was 1.54 (95% confidence interval (CI): 1.25-1.89; P proteinuria in the Asian population, which might have been affected by the associations of low rice intake with high blood pressure and diabetes. Future prospective studies are needed to confirm the results of this study.

    Understanding quality of life and participation is a key aspect of occupational therapy research. The use of smartphones to deliver experience-sampling surveys may provide an accessible way to monitor these outcomes. This study used smartphone-based experience sampling methods (ESM) to investigate factors influencing momentary quality of life (mQOL) of university students. A convenience sample of students at an Australian university participated. Using a custom smartphone application, ESM surveys were sent six to eight times, every second day, over a week. Participants indicated their mQOL, occupational participation, occupational enjoyment, social context and location via surveys and provided demographic and health information in a single self-report questionnaire. The relationship between mQOL and variables was analysed at the survey level using logistic regression. Forty students completed 391 surveys. Higher mQOL was significantly related to participation in productive occupations (z = 3.48; P = 0.001), moderate (z = 4.00; P sample, analysing at the individual level, and using ESM in conjunction with other methodologies is recommended. © 2017 Occupational Therapy Australia.

    Full Text Available Abstract Background Many epidemiological and public health surveys report increasing difficulty obtaining high participation rates. We conducted a pilot follow-up study to determine whether a mailed or telephone survey would better facilitate data collection in a subset of respondents to an earlier telephone survey conducted as part of the National Birth Defects Prevention Study. Methods We randomly assigned 392 eligible mothers to receive a self-administered, mailed questionnaire (MQ or a computer-assisted telephone interview (CATI using similar recruitment protocols. If mothers gave permission to contact the fathers, fathers were recruited to complete the same instrument (MQ or CATI as mothers. Results Mothers contacted for the MQ, within all demographic strata examined, were more likely to participate than those contacted for the CATI (86.6% vs. 70.6%. The median response time for mothers completing the MQ was 17 days, compared to 29 days for mothers completing the CATI. Mothers completing the MQ also required fewer reminder calls or letters to finish participation versus those assigned to the CATI (median 3 versus 6, though they were less likely to give permission to contact the father (75.0% vs. 85.8%. Fathers contacted for the MQ, however, had higher participation compared to fathers contacted for the CATI (85.2% vs. 54.5%. Fathers recruited to the MQ also had a shorter response time (median 17 days and required fewer reminder calls and letters (median 3 reminders than those completing the CATI (medians 28 days and 6 reminders. Conclusions We concluded that offering a MQ substantially improved participation rates and reduced recruitment effort compared to a CATI in this study. While a CATI has the advantage of being able to clarify answers to complex questions or eligibility requirements, our experience suggests that a MQ might be a good survey option for some studies.

    Despite the health benefits associated with children's sport participation, the occurrence of injury in this context is common. The extent to which sport injuries impact children's ongoing involvement in sport is largely unknown. Surveys have been shown to be useful for collecting children's injury and sport participation data; however, there are currently no published instruments which investigate the impact of injury on children's sport participation. This study describes the processes undertaken to assess the validity of two survey instruments for collecting self-reported information about child cricket and netball related participation, injury history and injury risk perceptions, as well as the reliability of the cricket-specific version. Face and content validity were assessed through expert feedback from primary and secondary level teachers and from representatives of peak sporting bodies for cricket and netball. Test-retest reliability was measured using a sample of 59 child cricketers who completed the survey on two occasions, 3-4 weeks apart. Based on expert feedback relating to face and content validity, modification and/or deletion of some survey items was undertaken. Survey items with low test-retest reliability (κ≤0.40) were modified or deleted, items with moderate reliability (κ=0.41-0.60) were modified slightly and items with higher reliability (κ≥0.61) were retained, with some undergoing minor modifications. This is the first survey of its kind which has been successfully administered to cricketers aged 10-16 years to collect information about injury risk perceptions and intentions for continued sport participation. Implications for its generalisation to other child sport participants are discussed.

    A sound decision regarding combination of datasets is critical for research validity. Data were collected between 1996 and 2000 via a 99-item survey of substance use behaviors. Two groups of 7th-12th grade students in predominately White communities are compared: 166,578 students from 193 communities with high survey participation and 41,259 students from 65 communities with lower participation. Hierarchical logistic models are used to explore whether the two datasets may be combined for further study of community-level substance use effects. "Scenario analysis" is introduced. Results suggest the datasets may reasonably be combined. Limitations and further research are discussed.

    A graduate degree is required of nursing faculty in America. Because of the nursing faculty shortage, web-based graduate nursing programs are being offered to encourage nurses to return to school. The identification of deterrents to participating in these programs is an important step in increasing enrollment. To identify deterrents to participation in web-based graduate nursing programs. Descriptive survey research. Louisiana Two hundred and eighty-one registered nurse members of the Louisiana Nurses' Association. The 54-item four-point Likert-type interval scale Deterrents to Participation in Web-Based Graduate Nursing Programs Survey Instrument was used. Data were collected over 8weeks using SurveyMonkey.com to administer the web survey tool to all members of the Louisiana State Nurses' Association. A factor analysis revealed a three-factor solution that explained 55.436% of the total variance in deterrents to participation in web-based graduate nursing programs. The factors were labeled "concerns about quality, cost, and time," "concerns about access to resources: technological and personal," and "concerns about electronic mediated communication." Multiple regression analysis revealed an overall model of three predictors of deterrents to participation in web-based graduate nursing programs: no computer literacy, annual household income between 20,000 and 50,000 dollars, and having the current educational status of graduating from a diploma RN program. This model accounted for 21% of the variance in the deterrents to participation scores. Since these three significant predictors of deterrents to participation in web-based graduate nursing programs were identified, web-based nursing graduate program administrators might consider an outreach to RN diploma graduates in an effort to make them aware of available technology support programs to foster participation. Scholarships for lower income nursing students are recommended, and programs to support computer

    Hundreds of thousands of volunteers take part in medical research, but many will never hear from researchers about what the study revealed. There is a growing demand for the results of randomised trials to be fed back to research participants both for ethical research practice and for ensuring their co-operation in a trial. This study aims to determine participants' preferences for type of leaflet (short versus long) used to summarise the findings of a randomised trial; and to test whether certain characteristics explained participants' preferences. 553 participants in a randomised trial about General Practitioners' access to Magnetic Resonance Imaging for patients presenting with suspected internal derangement of the knee were asked in the final follow-up questionnaire whether they would like to be fed back the results of the trial. Participants who agreed to this were included in a postal questionnaire survey asking about their preference, if any, between a short and a long leaflet and what it was about the leaflet that they preferred. Multinomial logistic regression was used to test whether certain demographics of responding participants along with treatment group explained whether a participant had a preference for type of leaflet or no preference. Of the participants who returned the final follow-up questionnaire, 416 (88%) agreed to receive the results of the trial. Subsequently 132 (32%) participants responded to the survey. Most participants preferred the longer leaflet (55%) and the main reasons for this were the use of technical information (94%) and diagrams (89%). There was weak evidence to suggest that gender might explain whether participants have a preference for type of leaflet or not (P = 0.084). Trial participants want to receive feed back about the results and appear to prefer a longer leaflet. Males and females might require information to be communicated to them differently and should be the focus of further research. The trial is registered

    To establish a baseline overall response rate for surveys of health professions trainees, determine strategies associated with improved response rates, and evaluate for the presence of nonresponse bias. The authors performed a comprehensive analysis of all articles published in Academic Medicine, Medical Education, and Advances in Health Sciences Education in 2013, recording response rates. Additionally, they reviewed nonresponse bias analyses and factors suggested in other fields to affect response rate including survey delivery method, prenotification, and incentives. The search yielded 732 total articles; of these, 356 were research articles, and of these, 185 (52.0%) used at least one survey. Of these, 66 articles (35.6%) met inclusion criteria and yielded 73 unique surveys. Of the 73 surveys used, investigators reported a response rate for 63.0% of them; response rates ranged from 26.6% to 100%, mean (standard deviation) 71.3% (19.5%). Investigators reported using incentives for only 16.4% of the 73 surveys. The only survey methodology factor significantly associated with response rate was single- vs. multi-institutional surveys (respectively, 74.6% [21.2%] vs. 62.0% [12.8%], P = .022). Notably, statistical power for all analyses was limited. No articles evaluated for nonresponse bias. Approximately half of the articles evaluated used a survey as part of their methods. Limited data are available to establish a baseline response rate among health professions trainees and inform researchers which strategies are associated with higher response rates. Journals publishing survey-based health professions education research should improve reporting of response rate, nonresponse bias, and other survey factors.

    1986-12-01

    This study investigates regional differentials in female labor force participation rates by educational status in Indonesia, using data from the 1961, 1971, and 1980 censuses. Rates in the Javanese areas are always well above the Indonesian average; in mainly Sundanese West Java they are much lower than the average, and in South Sulawesi they are lower still. Kalimantan is the only region where there is no stability in rates over time, possibly due to the inaccessibility of much of its population for census-taking. When only urban areas are considered, the regional differentials do not alter very much. As in most of the world, participation rates for single women are higher than those of married women, and those for divorced and widowed women are higher still. Participation rates are lowest of all for women with a junior high school education, rise for those witha senior high school education; and rise sharply for those with a university or academy education. The provinces with the highest urban female labor force participation rates--Yogyakarta, Central Java, East Java, and Bali--are among the poorest provinces in Indonesia. Female labor force participation rates in Indonesia are much higher than in other Moslem countries. Geographic and socioeconomic differentials in female labor force participation rates in Indonesia are not an artifact of inconsistencies in the data, but can be related to 2 other sets of explanatory variables: 1) economic needs and opportunities and 2) cultural differences.

    The continued participation of volunteers in clinical trials is crucial to advances in healthcare. Few data are available regarding the satisfaction and impressions of healthy volunteers after participation in phase I trials, many of which lead to unexpected adverse events. We report feedback from over 100 adult volunteers who took part in a first-in-human trial conducted in a high-income country testing an experimental Ebola vaccine causing significant reactogenicity, as well as unexpected arthritis in one fifth of participants. The anonymous, internet-based satisfaction survey was sent by email to all participants upon their completion of this one-year trial; it asked 24 questions concerning volunteers’ motivations, impressions of the trial experience, and overall satisfaction. Answers were summarized using descriptive statistics. Of the 115 trial participants, 103 (90%) filled out the survey. Fifty-five respondents (53%) were male. Thirty-five respondents (34%) were healthcare workers, many of whom would deploy to Ebola-affected countries. All respondents cited scientific advancement as their chief motivation for participation, while 100/103 (97%) and 61/103 (59%) reported additional “humanitarian reasons” and potential protection from Ebolavirus, respectively. Although investigators had documented adverse events in 97% of trial participants, only 74 of 103 respondents (72%) recalled experiencing an adverse event. All reported an overall positive experience, and 93/103 (90%) a willingness to participate in future trials. Given the high level of satisfaction, no significant associations could be detected between trial experiences and satisfaction, even among respondents reporting adverse events lasting weeks or months. Despite considerable reactogenicity and unexpected vaccine-related arthritis, all survey respondents reported overall satisfaction. While this trial’s context was unique, the positive feedback is likely due at least in part to the intense

    Limited attention has been given to the optimal strategies for retaining racial and ethnic minorities within studies and during the follow-up period. High attrition limits the interpretation of results and reduces the ability to translate findings into successful interventions. This study examined the retention strategies used by researchers when retaining minorities in research studies. From May to August 2010, we conducted an online survey with researchers (principal investigators, research staff, and IRB members) and examined their use of seven commonly used retention strategies. The number and type of retention strategies used, how these strategies differ by researcher type, and other characteristics (e.g., funding) were explored. We identified three clusters of researchers: comprehensive retention strategy researchers - utilized the greatest number of retention strategies; moderate retention strategy researchers - utilized an average number of retention strategies; and limited retention strategy researchers - utilized the least number of retention strategies. The comprehensive and moderate retention strategy researchers were more likely than the limited retention strategy researchers to conduct health outcomes research, work with a community advisory board, hire minority staff, use steps at a higher rate to overcome retention barriers, develop new partnerships with the minority community, modify study materials for the minority population, and allow staff to work flexible schedules. This study is a novel effort to characterize researchers, without implying a value judgment, according to their use of specific retention strategies. It provides critical information for conducting future research to determine the effectiveness of using a combination of retention strategies.

    Routine colorectal screening, decreases in incidence, and advances in treatment have lowered colorectal cancer mortality rates over the past three decades. Nevertheless, it remains the second most common cause of cancer death amongst men and women combined in U.S. Most cases of colon cancer are diagnosed at a late stage leading to poor survival outcomes for patients. After extensive research of publically available data, it would appear that the state of Connecticut does not have available state-wide data on patient wait times for routine colonoscopy screening. Furthermore, there are no publicly available, or Connecticut-specific, reports on Medicaid participation rates for colorectal screening amongst gastroenterologists (GI) in Connecticut. In 2012, the American Cancer Society report on Colorectal Cancer Screening Rates confirmed barriers to health-care access and disparities in health outcomes and survival rates for colon cancer patients based on race, ethnicity, and low socioeconomic status. Given this information, one could conjecture that low Medicaid participation rates among GIs could potentially have a more severe impact on health-care access and outcomes for underserved populations. At present, funding and human resources are being employed across the state of Connecticut to address bottlenecks in colorectal cancer screening. More specifically, patient navigation and outreach programs are emerging and expanding to address the gaps in services for hard-to-reach populations and the medically underserved. Low Medicaid participation rates and increased wait times for colonoscopy screening may impair the efficacy of colorectal cancer patient navigation and outreach efforts and potentially funding for future interventions. In this study, we report the results of our secret-shopper telephone survey comprising of 93 group and independent gastroenterologist (GI) practices in different counties of Connecticut.

    Full Text Available Background: Cancer-screening programs are effective in reducing cancer prevalence and mortality; however, cancer remains the leading cause of death in elderly people in Korea. The aim of this study was to identify the factors associated with elders’ participation in the National Cancer Screening Program (NCSP and differences in screening rates by gender.Methods: Original data from the Korea National Health and Nutrition and Examination Survey were analyzed by logistic regression analysis. The sample consisted of 5,505 elderly individuals over age 60. Selected demographic variables, cancer screening participation, physical and psychological health status, and lifestyle were examined.Results: The NCSP participation rates decreased in both men and women as age increased. Private medical insurance (OR 95% CI: 1.04–1.78, one or more chronic disease (OR 95% CI: 1.07–1.71, and current smoker (OR 95% CI: 0.52–0.94 had the strongest associations with cancer screening participation among men after multivariate adjustment. In contrast, cancer screening participation among women was significantly associated only with living place (OR 95% CI: 1.06–2.203 after multivariate adjustment.Conclusions: Effective health promoting interventions for elders require individualized programs that address gender-related factors associated with elders’ participation in cancer screening programs.

    There are many challenges in recruiting and engaging participants when conducting research, especially with HIV-positive individuals. Some of these challenges include geographical barriers, insufficient time and financial resources, and perceived HIV-related stigma. This paper describes the methodology of a recruitment approach that capitalized on existing online social media venues and other Internet resources in an attempt to overcome some of these barriers to research recruitment and retention. From May through August 2013, a campaign approach using a combination of online social media, non-financial incentives, and Web-based survey software was implemented to advertise, recruit, and retain participants, and collect data for a survey study with a limited budget. Approximately US $5,000 was spent with a research staff designated at 20% of full-time effort, yielding 2034 survey clicks, 1404 of which met the inclusion criteria and initiated the survey, for an average cost of US $3.56 per survey initiation. A total of 1221 individuals completed the survey, yielding 86.97% retention. These data indicate that online recruitment is a feasible and efficient tool that can be further enhanced by sophisticated online data collection software and the addition of non-financial incentives.

    Neuropsychological research frequently uses non-clinical undergraduate participants to evaluate neuropsychological tests. However, a recent study by An and colleagues (2012, Archives of Clinical Neuropsychology, 27, 849-857) called into question that the extent to which the interpretation of these participants' performance on neuropsychological tests is valid. This study found that in a sample of 36 participants, 55.6% exhibited performance invalidity at an initial session and 30.8% exhibited performance invalidity at a follow-up session. The current study attempted to replicate these findings in a larger, more representative sample using a more rigorous methodology. Archival data from 133 non-clinical undergraduate research participants were analyzed. Participants were classified as performance invalid if they failed any one PVT. In the current sample, only 2.26% of participants exhibited performance invalidity. Thus, concerns regarding insufficient effort and performance invalidity when using undergraduate research participants appear to be overstated.

    Little is known about the impact of personality disorder (PD) on the health of people living in the community. The authors set out to examine the association between PD and general health, using a cross-sectional survey of a representative community sample in London, UK. A total of 1,698 adults aged 16 years or over from 1,075 randomly selected households were recruited and interviewed face-to-face by trained interviewers. Using multivariable logistic regression, the authors examined the cross-sectional association between PD screen status, as assessed by the Standardised Assessment of Personality-Abbreviated Scale (SAPAS), and self-rated health, adjusting for demographic and health covariates. Of the participants, 14.5% screened positively for PD. A greater proportion of those scoring positively for PD reported poor self-rated health, compared to screen negative participants (41.3% versus 15.0%). This association was reduced, but remained significant, after adjustment for potential confounders (unadjusted odds ratio (OR) = 3.99, 95% CI [2.93, 5.42]; fully adjusted OR = 1.53, 95% CI [1.02, 2.29]. Of note, subthreshold symptoms of PD were significantly associated with poor self-rated health (unadjusted OR per unit SAPAS score increment = 1.53, 95% CI [1.40, 1.67]; fully adjusted OR = 1.19, 95% CI [1.07, 1.33]. Furthermore, people screening positive for PD were more likely to report multiple (three or more) long-standing illnesses. The authors conclude that in the general population, individuals who are at high risk for PD are independently at increased risk of poor general health.

    Background Web-based surveys have become a new and popular method for collecting data, but only a few studies have directly compared postal and Web-based surveys among physicians, and none to our knowledge among general practitioners (GPs). Objective Our aim is to compare two modes of survey delivery (postal and Web-based) in terms of participation rates, response times, and completeness of questionnaires in a study assessing GPs’ preventive practices. Methods This randomized study was conducted in Western Switzerland (Geneva and Vaud) and in France (Alsace and Pays de la Loire) in 2015. A random selection of community-based GPs (1000 GPs in Switzerland and 2400 GPs in France) were randomly allocated to receive a questionnaire about preventive care activities either by post (n=700 in Switzerland, n=400 in France) or by email (n=300 in Switzerland, n=2000 in France). Reminder messages were sent once in the postal group and twice in the Web-based group. Any GPs practicing only complementary and alternative medicine were excluded from the study. Results Among the 3400 contacted GPs, 764 (22.47%, 95% CI 21.07%-23.87%) returned the questionnaire. Compared to the postal group, the participation rate in the Web-based group was more than four times lower (246/2300, 10.70% vs 518/1100, 47.09%, Pparticipation in surveys while reducing costs.

    Survey researchers have long been exhorted to strive for high response rates in order to maximize the likelihood that the respondents are representative of the population being surveyed. It is not surprising then, that much survey research has been directed towards examining the effects of various manipulatable factors on response rate. It is clear that attempts to reach the goal of minimizing the likelihood of nonresponse bias through testing various methods of increasing survey response rates have consumed much research and debate. The results obtained in this research have been inconsistent. Some studies have found significant differences, others have found none. The present study was designed to determine the extent to which the results of an employment survey of former graduates of a teacher preparation program would have been affected by changes in response rate.

    Full Text Available BACKGROUND: The response rates to physician postal surveys remain modest. The primary objective of this study was to assess the effect of tracking responses on physician survey response rate (i.e., determining whether each potential participant has responded or not. A secondary objective was to assess the effects of day of mailing (Monday vs. Friday on physician survey response rate. METHODS: We conducted 3 randomized controlled trials. The first 2 trials had a 2 x 2 factorial design and tested the effect of day of mailing (Monday vs. Friday and of tracking vs. no tracking responses. The third trial tested the effect of day of mailing (Monday vs. Friday. We meta-analyzed these 3 trials using a random effects model. RESULTS: The total number of participants in the 3 trials was 1339. The response rate with tracked mailing was not statistically different from that with non-tracked mailing by the time of the first reminder (RR = 1.01 95% CI 0.84, 1.22; I²  =  0%. There was a trend towards lower response rate with tracked mailing by the time of the second reminder (RR = 0.91; 95% CI 0.78, 1.06; I²  =  0%. The response rate with mailing on Mondays was not statistically different from that with Friday mailing by the time of first reminder (RR = 1.01; 95% CI 0.87, 1.17; I²  =  0%, and by the time of the 2(nd reminder (RR = 1.08; 95% CI 0.84, 1.39; I²  =  77%. CONCLUSIONS: Tracking response may negatively affect physicians' response rate. The day of mailing does not appear to affect physicians' response rate.

    Many hot Jupiters (HJs) are detected by the Doppler and transit techniques. From surveys using these two techniques, however, the measured HJ occurrence rates differ by a factor of two or more. Using the California Planet Survey sample and the Kepler sample, we investigate the causes for this difference in the HJ occurrence rate. We find that 12.8% ± 0.24% of HJs are misidentified in the Kepler mission because of photometric dilution and subgiant contamination. We explore the differences between the Doppler sample and the Kepler sample that can account for the different HJ occurrence rate. We discuss how to measure the fundamental HJ occurrence rates by synthesizing the results from the Doppler and Kepler surveys. The fundamental HJ occurrence rates are measures of the HJ occurrence rate as a function of stellar multiplicity and evolutionary stage, e.g., the HJ occurrence rate for single and multiple stars or for main-sequence and subgiant stars.

    Research has shown minorities receive lower quality health care than White persons even with socioeconomic conditions controlled. This difference may partially be related to racially biased attitudes and impaired communication in interracial relationships between physicians and patients. This study investigated the effect of physicians' race and nonverbal communication style on participants' evaluations. Patients at a local health clinic were participants (N = 116: 84% Black, 16% White). Each participant viewed one of four videotapes showing varied race of a physician (Black or White) and the physician's nonverbal behavior (expressing concern or distance), and then completed a questionnaire evaluating the depicted physician. Overall, participants did not give significantly different preferences for physicians of the same race. However, participants' evaluations were significantly associated with physicians' nonverbal style. Nonverbal concern was associated with highest satisfaction, trust, self-disclosure, recall of information, likelihood of recommending the physician, and intent to comply with the physician's recommendations. When male and female participants were compared, preference for a physician of the same race was found only among male participants who viewed verbally distant physicians. Results suggest that social skills are more important than race in shaping patients' perceptions of physicians.

    Full Text Available In today’s world, congestion control is a main objective to maximize fairness, utilization and throughput of the Internet. Every protocol has its own features to handle the congestion. The most widely used protocol over the Internet is Transfer Control Protocol. It aims at reliable and in order delivery of bytes to the higher layer and it also protect the network from congestive control. Other congestion control protocols are XCP and RCP. These new protocols are advancement over TCP. We study new congestion control protocol like Rate Control Protocol that make flows complete frequently as compared to TCP and other version of TCP and XCP. In this paper we have presented a comparison between TCP, XCP and RCP, which shows that RCP is a superior choice to use over the Internet to make flows complete quickly

    Full Text Available Abstract Background Hundreds of thousands of volunteers take part in medical research, but many will never hear from researchers about what the study revealed. There is a growing demand for the results of randomised trials to be fed back to research participants both for ethical research practice and for ensuring their co-operation in a trial. This study aims to determine participants' preferences for type of leaflet (short versus long used to summarise the findings of a randomised trial; and to test whether certain characteristics explained participants' preferences. Methods 553 participants in a randomised trial about General Practitioners' access to Magnetic Resonance Imaging for patients presenting with suspected internal derangement of the knee were asked in the final follow-up questionnaire whether they would like to be fed back the results of the trial. Participants who agreed to this were included in a postal questionnaire survey asking about their preference, if any, between a short and a long leaflet and what it was about the leaflet that they preferred. Multinomial logistic regression was used to test whether certain demographics of responding participants along with treatment group explained whether a participant had a preference for type of leaflet or no preference. Results Of the participants who returned the final follow-up questionnaire, 416 (88% agreed to receive the results of the trial. Subsequently 132 (32% participants responded to the survey. Most participants preferred the longer leaflet (55% and the main reasons for this were the use of technical information (94% and diagrams (89%. There was weak evidence to suggest that gender might explain whether participants have a preference for type of leaflet or not (P = 0.084. Conclusions Trial participants want to receive feed back about the results and appear to prefer a longer leaflet. Males and females might require information to be communicated to them differently and should

    The objective was to assess the degradation of speech sound quality produced by frequency compression for listeners with extensive high-frequency dead regions (DRs). Quality ratings were obtained using values of the starting frequency (Sf) of the frequency compression both below and above the estimated edge frequency, fe, of each DR. Thus, the value of Sf often fell below the lowest value currently used in clinical practice. Several compression ratios were used for each value of Sf. Stimuli were sentences processed via a prototype hearing aid based on Phonak Exélia Art P. Five participants (eight ears) with extensive high-frequency DRs were tested. Reductions of sound-quality produced by frequency compression were small to moderate. Ratings decreased significantly with decreasing Sf and increasing CR. The mean ratings were lowest for the lowest Sf and highest CR. Ratings varied across participants, with one participant rating frequency compression lower than no frequency compression even when Sf was above fe. Frequency compression degraded sound quality somewhat for this small group of participants with extensive high-frequency DRs. The degradation was greater for lower values of Sf relative to fe, and for greater values of CR. Results varied across participants.

    Full Text Available Abstract:Background and objectives: Social health as third dimension of health, along with physical and mental health, has drawn more attention in recent years among policy makers and health system managers. No other study, to our knowledge, has documented measuring individual-level social health in Iran. In response to this need, our study tends to assess Iranians self-rated social health through conducting a survey in 3 cities of Iran. Methods: We conducted a survey using cross sectional method in three cities of Iran included people more than 18 years old. We use a random sample size of 800 people. The scale provides a total score of social health and three sub-scores. Total score was calculated by summing all 33 items, so the range was between 33 to 165, considering that higher score indicating better social health. Psychometric parameters of scale were acceptable. To interpret scores, respondents were categorized into five ordered groups as quintiles for amount of social health. To compare social health scores in different demographic groups multiple linear regression was employed to interpret association between demographic variables and social health score. Results: From a pool of 800 persons, 794 (99% agreed to participate and filled out the questionnaire completely.  The mean of self-rated social health score was 105.0 (95% confidence interval, 103.8 to 106.2. 50% of participants had medium level of social health. social health score was higher for those who live in Urmia as a small city in comparison with big cities- Tehran and Isfahan (P V< 0.001 and was lower for unemployed people (PV= 0.029. There was no association between social health score and other factors such as sex, age and educational level (PV>0.05 Conclusion:This study may be considered as the first step in evidence-based policy-making in the field of social health in Iran.

Data are presented using descriptive statistics, and the χ(2) test served to compare the results among supervisors with the earlier data from the longitudinal survey of doctoral students. Not applicable. This survey is an observational study. Of 3653 potential participants, 1069 (29.3%) supervising 3744 doctoral candidates participated in the study. Supervisors considered themselves to be highly motivated and to offer adequate supervision. On the other hand, 87% stated that they did not feel well prepared for thesis supervision. Supervisors gave lack of timeliness of doctoral students and personal differences (p=0.024 and p=0.001) as the main reasons for terminating thesis projects. Doctoral students predominantly mentioned methodological problems and difficult subjects as critical issues (p=0.001 and pthesis supervisors and medical students feel ill prepared for their roles in the process of a medical dissertation.

    2009-07-01

    Based on extensive questionnaire data, this paper focuses on parents' views about children's right to decide about participation in research. The data originates from 4000 families participating in a longitudinal prospective screening as 1997. Although current regulations and recommendations underline that children should have influence over their participation, many parents in this study disagree. Most (66%) were positive providing information to the child about relevant aspects of the study. However, responding parents were split about whether or not children should at some point be allowed decisional authority when participating in research: 41.6% of the parents reported being against or unsure. Those who responded positively believed that children should be allowed to decide about blood-sampling procedures (70%), but to a less extent about participation (48.5%), analyses of samples (19.7%) and biological bank storage (15.4%). That as many as possible should remain in the study, and that children do not have the competence to understand the consequences for research was strongly stressed by respondents who do not think children should have a right to decide. When asked what interests they consider most important in paediatric research, child autonomy and decision-making was ranked lowest. We discuss the implications of these findings.

    Gun buyback programs represent one arm of a multipronged approach to raise awareness and education about gun safety. The city of Worcester, MA has conducted an annual gun buyback at the Police Department Headquarters since 2002. We analyzed survey responses from a voluntary, 18-question, face-to-face structured interview from December 2009 to June 2015 using descriptive statistics to determine participant demographics and motivations for participation. A total of 943 guns were collected, and 273 individuals completed surveys. The majority of participants were white males older than 55years (42.4%). Participants represented 61 zip codes across Worcester County, with 68% having prior gun safety training and 61% with weapons remaining in the home (27% of which children could potentially access). The top reasons for turning in guns were "no longer needed" (48%) and "fear of children accessing the gun" (14%). About 1 in 3 respondents knew someone injured/killed by gun violence. Almost all (96%) respondents claimed the program raised community awareness of firearm risk. The Worcester Goods for Guns Buyback has collected more than 900 guns between 2009 and 2015. The buyback removes unwanted guns from homes and raises community awareness about firearm safety. Copyright © 2017 Elsevier Inc. All rights reserved.

    Evidence for the effectiveness of the morbidity and mortality conferences in improving patient safety is lacking. The aim of this survey was to assess the opinion of participants concerning the benefits and the functioning of morbidity and mortality conferences, according to their organizational characteristics. We conducted a survey of professionals involved in a morbidity and mortality conference using a self-administered questionnaire in three French teaching hospitals in 2012. The questionnaire focused on the functioning of morbidity and mortality conferences, the perceived benefits, the motivations of participants, and how morbidity and mortality conferences could be improved. The perception of participants was analysed according to the characteristics of morbidity and mortality conferences. A total of 698 participants in 54 morbidity and mortality conferences completed the questionnaire. Most of them (91 %) were satisfied with how the morbidity and mortality conference they attended was conducted. The improvements in healthcare quality and patient safety were the main benefits perceived by participants. Effectiveness in improving safety was mainly perceived when cases were thoroughly analysed (adjusted odds ratio [a0R] =2.31 [1.14-4.66]). The existence of a written charter (p = 0.05), the use of a standardized case presentation (p = 0.049), and prior dissemination of the meeting agenda (p = 0.02) were also associated with the perception of morbidity and mortality conference effectiveness. The development and achievement of improvement initiatives were associated with morbidity and mortality conferences perceived as being more effective (p < 0.01). Participants suggested improving the attendance of medical and paramedical professionals to enhance the effectiveness of morbidity and mortality conferences. Morbidity and mortality conferences were positively perceived. These results suggest that a structured framework and thoroughly analyzing

    2014-06-01

    Full Text Available INTRODUCTION: Most exercise studies for older adults have been university- or hospital-based. Little is known about the benefits and factors influencing long-term participation in community-based exercise programmes, especially in New Zealand. AIM: To quantify the objective benefits, participant perceptions and retention rates of a New Zealand community-based exercise programme for adults (60 years or older. METHODS: Study 1 involved assessing the benefits of 12 weeks’ training on a convenience sample of 62 older adults commencing the never2old Active Ageing programme. Study 2 assessed the perceptions of 150 current participants on a variety of programme components that could act as barriers or facilitators to continued engagement. Study 3 assessed the retention rates of 264 participants in the programme over a two-year period. RESULTS: Significant improvements in many physical functional scores were observed in Study 1 (5–30 percentile points; p<0.05. Questionnaire responses from participants in Study 2 indicated many perceived benefits (positive responses from 67–95% on various questions and that core components of the programme were rated very highly (64–99% on various components. Retention rates were high, with Study 3 finding 57% of participants still engaging in the programme at the end of the two-year period. DISCUSSION: A community-based exercise programme for older adults can improve many objective and subjective measures of physical fitness and functional performance and have good retention rates. General practitioners and other allied health professionals in New Zealand should consider promoting programmes, such as the never2old Active Ageing programme, to their older patients.

    2010-06-01

    Full Text Available Abstract Background Evidence suggests that survey response rates are decreasing and that the level of survey response can be influenced by questionnaire length and the use of pre-notification. The goal of the present investigation was determine the effect of questionnaire length and pre-notification type (letter vs. postcard on measures of survey quality, including response rates, response times (days to return the survey, and item nonresponse. Methods In July 2008, the authors randomized 900 residents of Olmsted County, Minnesota aged 25-65 years to one of two versions of the Talley Bowel Disease Questionnaire, a survey designed to assess the prevalence of functional gastrointestinal disorders (FGID. One version was two pages long and the other 4 pages. Using a 2 × 2 factorial design, respondents were randomized to survey length and one of two pre-notification types, letter or postcard; 780 residents ultimately received a survey, after excluding those who had moved outside the county or passed away. Results Overall, the response rates (RR did not vary by length of survey (RR = 44.6% for the 2-page survey and 48.4% for the 4-page or pre-notification type (RR = 46.3% for the letter and 46.8% for the postcard. Differences in response rates by questionnaire length were seen among younger adults who were more likely to respond to the 4-page than the 2-page questionnaire (RR = 39.0% compared to 21.8% for individuals in their 20s and RR = 49.0% compared to 32.3% for those in their 30s. There were no differences across conditions with respect to item non-response or time (days after mailing to survey response. Conclusion This study suggests that the shortest survey does not necessarily provide the best option for increased response rates and survey quality. Pre-notification type (letter or postcard did not impact response rate suggesting that postcards may be more beneficial due to the lower associated costs of this method of contact.

    Based on the data of households' financial assets in the cities of China in 2007 and 2012 collected by Beijing Ordo Consultant Center, this paper surveys the Chinese urban residents' attitude to the stock market, their participant behaviors and the various influencing factors behind them. It finds that savings take a lion' s share in Chinese households' financial assets and the household income has polarized. The empirical results reveal that age, income and educational background have significantly positive effect on residents' equity investment participation; risk attitudes, social interaction, real estate proportion and career risk are important factors influencing the participation. Moreover, credit constraint and social interaction impact the extend of residents' participation significantly. Compared with that of 2007, both Chinese household asset and income increased obviously in 2012, and the income polarization has intensified, but the degree of equity investment has decreased. Except for age, education and income, the influencing factors on the participant behaviors are dynamically changeable, viz. Chinese residents' attitude to stock market and their participation vary as the environment of financial markets changes.%本文考察了中国城镇居民对股票市场的态度、参与现状及其影响因素。描述性统计表明:储蓄在家庭金融资产中所占比例较大;家庭收入两极分化。实证研究发现:年龄、收入和教育程度对股市参与有显著的正向影响;风险态度、社会互动、房产比例、职业风险等是股市参与的重要影响因素;信贷约束和社会互动是影响股市参与程度的重要因素。不同时期的对比分析表明:较之2007年,中国居民家庭资产和家庭收入水平在2012年有明显提高,收入两极分化的现象更为严重,但居民的股市参与和参与程度都出现了明显下降;除了年龄、教育年限和收入

    2015-12-01

    Demographic characteristics associated with gambling participation and problem gambling severity were investigated in a stratified random survey in Tasmania, Australia. Computer-assisted telephone interviews were conducted in March 2011 resulting in a representative sample of 4,303 Tasmanian residents aged 18 years or older. Overall, 64.8% of Tasmanian adults reported participating in some form of gambling in the previous 12 months. The most common forms of gambling were lotteries (46.5%), keno (24.3%), instant scratch tickets (24.3%), and electronic gaming machines (20.5%). Gambling severity rates were estimated at non-gambling (34.8%), non-problem gambling (57.4%), low risk gambling (5.3%), moderate risk (1.8%), and problem gambling (.7%). Compared to Tasmanian gamblers as a whole significantly higher annual participation rates were reported by couples with no children, those in full time paid employment, and people who did not complete secondary school. Compared to Tasmanian gamblers as a whole significantly higher gambling frequencies were reported by males, people aged 65 or older, and people who were on pensions or were unable to work. Compared to Tasmanian gamblers as a whole significantly higher gambling expenditure was reported by males. The highest average expenditure was for horse and greyhound racing ($AUD 1,556), double the next highest gambling activity electronic gaming machines ($AUD 767). Compared to Tasmanian gamblers as a whole problem gamblers were significantly younger, in paid employment, reported lower incomes, and were born in Australia. Although gambling participation rates appear to be falling, problem gambling severity rates remain stable. These changes appear to reflect a maturing gambling market and the need for population specific harm minimisation strategies.

    The Conservation Reserve Program (CRP) established under the 1985 Food Security Act was initially designed to provide the agricultural community economic assistance while protecting highly erodible cropland. Many of the environmental benefits to soil, water, and wildlife resources have been documented (Dunn and others, 1993; Ryan and others, 1998; Flather and others, 1999; Heard and others, 2000). However, the personal and social effects of the program on CRP participants (or contractees) had not been formally documented. Information had been limited to anecdotal comments from individual participants, such as: “since establishment of the CRP the streams have surface water in them” or “the CRP grasses capture drifting snow, making winter feeding of cattle easier.” The Farm Service Agency (FSA) and Natural Resources Conservation Service (NRCS) wanted to have a better picture of the strengths and weaknesses of the program, according to those most affected by it. In addition, policy makers wanted to get input from program participants on the growing emphasis of the program on long-term management and wildlife habitat requirements.

    2009-01-01

    Centers for independent living (CILs) provide critical supports, services, and advocacy for assisting people with disabilities in living independently. As there is a rapidly increasing population of older people with disabilities, many CILs are now considering how to actively engage older adults in their organizations. This study utilized a survey of older people with disabilities to help identify social marketing techniques that community organizations like CILs can use to effectively reach older people with disabilities. Utilizing the components of the social marketing mix in designing outreach efforts, including a critical examination of product, place, price, participants, and partnering, CILs and other community agencies can better reach older adults with disabilities.

    Wessely Simon C

    2010-10-01

    Full Text Available Abstract Background Monetary incentives are an effective way of increasing response rates to surveys, though they are generally less effective in physicians, and are more effective when the incentive is paid up-front rather than when made conditional on completion. Methods In this study we examine the effectiveness of pre- and post-completion incentives on the response rates of all the neurologists in the UK to a survey about conversion disorder, using a cluster randomised controlled design. A postal survey was sent to all practicing consultant neurologists, in two rounds, including either a book token, the promise of a book token, or nothing at all. Results Three hundred and fifty-one of 591 eligible neurologists completed the survey, for a response rate of 59%. While the post-completion incentive exerted no discernible influence on response rates, a pre-completion incentive did, with an odds-ratio of 2.1 (95% confidence interval 1.5 - 3.0. Conclusions We conclude that neurologists, in the UK at least, may be influenced to respond to a postal survey by a pre-payment incentive but are unaffected by a promised reward.

  19. Getting physicians to open the survey: little evidence that an envelope teaser increases response rates

    Directory of Open Access Journals (Sweden)

    Ziegenfuss Jeanette Y

    2012-03-01

    Full Text Available Abstract Background Physician surveys are an important tool to assess attitudes, beliefs and self-reported behaviors of this policy relevant group. In order for a physician to respond to a mailed survey, they must first open the envelope. While there is some evidence that package elements can impact physician response rates, the impact of an envelope teaser is unknown. Here we assess this by testing the impact of adding a brightly colored "$25 incentive" sticker to the outside of an envelope on response rates and nonresponse bias in a survey of physicians. Methods In the second mailing of a survey assessing physicians' moral beliefs and views on controversial health care topics, initial nonrespondents were randomly assigned to receive a survey in an envelope with a colored "$25 incentive" sticker (teaser group or an envelope without a sticker (control group. Response rates were compared between the teaser and control groups overall and by age, gender, region of the United States, specialty and years in practice. Nonresponse bias was assessed by comparing the demographic composition of the respondents to the nonrespondents in the experimental and control condition. Results No significant differences in response rates were observed between the experimental and control conditions overall (p = 0.38 or after stratifying by age, gender, region, or practice type. Within the teaser condition, there was some variation in response rate by years since graduation. There was no independent effect of the teaser on response when simultaneously controlling for demographic characteristics (OR = 0.875, p = 0.4112. Conclusions Neither response rates nor nonresponse bias were impacted by the use of an envelope teaser in a survey of physicians in the United States.

    We use the Sloan Digital Sky Survey II Supernova Survey (SDSS-II SNS) data to measure the volumetric core collapse supernova (CCSN) rate in the redshift range (0.03 < z < 0.09). Using a sample of 89 CCSN, we find a volume-averaged rate of 1.06 ± 0.19 × 10(–)(4)((h/0.7)(3)/(yr Mpc(3))) at a mean redshift of 0.072 ± 0.009. We measure the CCSN luminosity function from the data and consider the implications on the star formation history.

    The intersections between chronicity, disability and social inequality are well understood. Novel ways to counter the social determinants of health and disability are needed. Men's Sheds are a community space where men can participate in a range of shared activities and potentially experience a health and social benefits. This cross-sectional survey was conducted to inform future research by determining who attended Men's Sheds and the range of health, social, community, and educational activities undertaken there. This paper explores the membership of people with disabilities (PWD) at Men's Sheds and the factors that predict their membership. An online survey link was sent to all known Men's Sheds internationally in 2012. Data were analyzed using descriptive and inferential (univariate and multivariate) statistics. 32.2% of international sheds and 29% of Australian sheds specifically targeted the inclusion of PWD. 80% of these sheds have significantly more members with disabilities than sheds who do no target PWD. Factors associated with greater membership of PWD included the provision of transport, social outings and promoting occupational skills. PWD are being encouraged to join and are joining Men's Sheds. This is significant as the value of participation and inclusion toward better health and wellbeing is well known. Men's Sheds offer a community space where the social determinants of chronicity and disability can potentially be countered. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Single item questions about self ratings of overall health status are widely used in both military and civilian surveys. Limited information is available to date that examines what relationships exist between self-rated health, health status and health related behaviors among relatively young, healthy individuals. Methods The current study uses the population of active duty United States Air Force recruits (N = 31,108. Participants completed surveys that asked about health behaviors and health states and were rated their health on a continuum from poor to excellent. Results Ratings of health were consistently lower for those who used tobacco (F = 241.7, p Conclusion Given the consistent relationship between self-rated overall health and factors important to military health and fitness, self-rated health appears to be a valid measure of health status among young military troops.

    Adherence to physical activity and dietary interventions is a common challenge. Interventions that use group cohesion strategies show promise for increasing adherence, but have not been tested among women of color. The purpose of this study was to determine whether dimensions of group cohesion mediate the association between intervention condition and attendance within a community physical activity program for women of color. African American and Hispanic or Latina women (N = 310) completed measurements at baseline and post-intervention and participated in a social cohesion intervention to improve physical activity and dietary habits. Women were assigned to a physical activity or fruit and vegetable intervention group. Social and task cohesion was measured using the Physical Activity Group Environment Questionnaire (PAGE-Q). Attendance was recorded at each of six intervention sessions. Women were generally middle-age (M age = 46.4 years, SD = 9.1) and obese (M BMI = 34.4 kg/m2, SD = 7.7). The estimate of the mediated effect was significant for all group cohesion constructs, indicating both task constructs-attraction to the group's task (SE = 0.096, CI: -0.599 to -0.221) and group integration around the task (SE = 0.060, CI: -0.092 to -0.328)-and social constructs-attraction to the group's social aspects (SE = 0.046, CI: -0.546 to -0.366) and group integration around social aspects (SE = 0.046, CI: -0.546 to -0.366)-significantly mediated the association between group assignment and attendance. Both task and social constructs are important to improve attendance in health promotion interventions for women of color.

  5. When "no" might not quite mean "no"; the importance of informed and meaningful non-consent: results from a survey of individuals refusing participation in a health-related research project

    Directory of Open Access Journals (Sweden)

    McMurdo Marion ET

    2007-04-01

    Full Text Available Abstract Background Low participation rates can lead to sampling bias, delays in completion and increased costs. Strategies to improve participation rates should address reasons for non-participation. However, most empirical research has focused on participants' motives rather than the reasons why non-participants refuse to take part. In this study we investigated the reasons why older people choose not to participate in a research project. Methods Follow-up study of people living in Tayside, Scotland who had opted-out of a cross-sectional survey on activities in retirement. Eight hundred and eighty seven people aged 65–84 years were invited to take part in a home-based cross-sectional survey. Of these, 471 refused to take part. Permission was obtained to follow-up 417 of the refusers. Demographic characteristics of people who refused to take part and the reasons they gave for not taking part were collected. Results 54% of those invited to take part in the original cross-sectional survey refused to do so. However, 61% of these individuals went on to participate in the follow-up study and provided reasons for their original refusal. For the vast majority of people initial non-participation did not reflect an objection to participating in research in principle but frequently stemmed from barriers or misunderstandings about the nature or process of the project itself. Only 28% indicated that they were "not interested in research". The meaningfulness of expressions of non-consent may therefore be called into question. Hierarchical log-linear modelling showed that refusal was independently influenced by age, gender and social class. However, this response pattern was different for the follow-up study in which reasons for non-participation in the first survey were sought. This difference in pattern and response rates supports the likely importance of recruitment issues that are research and context specific. Conclusion An expression of non

    Patient-reported outcome measures derived from quality of life instruments are an important tool in monitoring disease progression and treatment response. Although a number of validated instruments are available, the Short Form-36 (SF-36) quality of life survey is the most widely used. It is imperative that the patients answer all the questions in this instrument for appropriate analysis and interpretation. It has been hypothesized that fewer questions (i.e., the Short Form-12 [SF-12]), will result in greater survey completion rates. The present study was a randomized prospective study comparing the completion rates for the SF-36 and SF-12 quality of life surveys. Patients presenting with a chronic wound were asked to complete the SF-36 or SF-12 survey. After an a priori power analysis was performed, the completion rates, patterns of skipped questions, and demographic information were analyzed using t tests for continuous variables or Fisher's exact test for categorical variables and both multivariate linear regression and logistic regression. A total of 59 subjects (30 completed the SF-12 and 29 completed the SF-36) participated in the present study. The SF-12 group had an 80% (24 of 30) completion rate compared with a 55% (16 of 29) completion rate for the SF-36 group (p < .05). However, the length of the survey did not affect the completion rate nor was a statistically detectable pattern of skipped questions found. College graduates were more likely to complete both surveys compared with high school graduates (p < .07). Although it is unclear why, our study results indicate that the SF-12 yields a higher total survey completion rate. However, completion appears independent of the shorter survey length.

    Double reading as a quality assurance (QA) tool is employed extensively in Norwegian hospital radiology departments. The practice is resource consuming and regularly debated. To investigate the rates of double reading in Norwegian hospital radiology departments, to identify department characteristics associated with double reading rates, and to investigate associations between double reading and other quality improvement. We issued two parallel national surveys to management and to consultant radiologists, respectively. Management was defined as the chief medical officer and/or the head of the radiology department. The management survey covered staffing, perceived resource situation, double reading, guidelines, and quality improvement. The radiologist survey served to validate management responses concerning double reading. Management survey items concerning practices of quality improvement were organized into three indices reflecting different quality approaches, namely: appropriateness of investigations; personal performance feedback; and system performance feedback. The response rates of the surveys were 100% (45/45) for management and 55% (266/483) for radiologists. Of all exams read by consultants, 33% were double read. The double reading rate was highest in university hospital departments (59%), intermediate in other teaching departments (30%), and lowest in non-teaching departments (11%) (P = 0.01). Among the quality indices, mean scores were highest on appropriateness index (68%), intermediate on the person index (56%), and lowest on system index (37%). There were no correlations between double reading rates and scores on any of the quality indices. The rate of double reading in Norwegian hospital radiology is significantly correlated to department teaching status, but not to other practices of quality work. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    To investigate half marathon runners' frequency of use of recovery strategies, perceptions regarding the most beneficial recovery strategy and reasons for using recovery strategies. Cross-sectional survey. 186 participants of the 13.1 mile BUPA Great North Run 2013. A questionnaire was developed which required participants to indicate how frequently they used twelve different recovery strategies, identify which recovery strategy they believed to be most beneficial and rank six reasons for using recovery strategies in order of importance. Data was analysed using a Friedman non-parametric ANOVA and additional non-parametric tests. All participants used recovery strategies. Stretching was the most commonly used recovery strategy (p strategies such as kinesio tape (80%), hydrotherapy (78%) or ice baths (71%). A significant difference was observed between reasons for using recovery strategy (χ(2) (5) = 292.29, p important reasons for using recovery strategies, minor sex and age differences in the responses were identified. Recovery strategy usage appears to be widespread among half marathon runners; however disparities exist between the frequency of use and perceived effectiveness of different recovery strategies. Further research in this area is needed to facilitate the development of recovery strategy guidelines which are both evidence-based and practically relevant.

    The purpose of this study was to assess mental health clinicians' attitudes about mental health consumer participation in inpatient psychiatric units. A cross-sectional survey design was used with a non-probability sample of 47 clinicians in the psychiatric units of a large Australian hospital. The results showed that gender, length of time as a clinician, and how long the staff worked in the units influenced their attitudes about consumer involvement. Females were more likely than males to support consumer participation in management and consumer consultants. Less experienced staff showed greater support than more experienced staff for mental health consumer involvement in treatment-related matters and consumer consultants in units. New staff members were more likely to register agreement-to-uncertainty regarding consumer involvement in treatment-related issues, whereas established staff members were more likely to record uncertainty about this issue. The findings showed that although reports and policies promoted participation, some clinicians were reluctant to accept consumer and consultant involvement.

    To assess analytic approaches randomized controlled trial (RCT) authors use to address missing participant data (MPD) for patient-important continuous outcomes. We conducted a systematic survey of RCTs published in 2014 in the core clinical journals that reported at least one patient-important outcome analyzed as a continuous variable. Among 200 studies, 187 (93.5%) trials explicitly reported whether MPD occurred. In the 163 (81.5%) trials that reported the occurrence of MPD, the median and interquartile ranges of the percentage of participants with MPD were 11.4% (2.5%-22.6%).Among the 147 trials in which authors made clear their analytical approach to MPD, the approaches chosen included available data only (109, 67%); mixed-effect models (10, 6.1%); multiple imputation (9, 4.5%); and last observation carried forward (9, 4.5). Of the 163 studies reporting MPD, 16 (9.8%) conducted sensitivity analyses examining the impact of the MPD and (18, 11.1%) discussed the risk of bias associated with MPD. RCTs reporting continuous outcomes typically have over 10% of participant data missing. Most RCTs failed to use optimal analytic methods, and very few conducted sensitivity analyses addressing the possible impact of MPD or commented on how MPD might influence risk of bias.

    2015-01-01

    The measured redshift ($z$) of an astronomical object is a combination of Hubble recession, gravitational redshift and peculiar velocity. In particular, the line of sight distance to a galaxy inferred from redshift is affected by the peculiar velocity component of galaxy redshift, which can also be observed as an anisotropy in the correlation function. This anisotropy allows us to measure the linear growth rate of matter ($f\\sigma_8$). In this paper, we measure the linear growth rate of matter ($f\\sigma_8$) at $z=0.57$ using the CMASS sample from Data Release 11 of Sloan Digital Sky Survey III (SDSS III) Baryon Oscillations Spectroscopic Survey (BOSS). The galaxy sample consists of 690,826 Luminous Red Galaxies (LRGs) in the redshift range 0.43 to 0.7 covering 8498 deg$^2$. Here we report the first measurement of $f\\sigma_8$ and cosmology using Convolution Lagrangian Perturbation Theory (CLPT) with Gaussian streaming model (GSRSD). We arrive at a constraint of $f\\sigma_8=0.462\\pm0.041$ (9\\% accuracy) at effec...

    Breast cancer patients are as a rule in need of a multiple sequential in-patient, day-patient and out-patient permanent treatment. The required care demands a trans-sectoral networking of all multi-professional persons involved in diagnostics, therapies, rehabilitation and aftercare. A method to develop the integration of treatment processes, as well as thereby resulting in increased effectiveness and efficiency, can constitute the concept of case management. A prerequisite for an effective implementation of case management and thus the starting point of the present survey is a well-functioning network encompassing optimal cooperation. Within the framework of the evaluation of the case management-based integrated care model "mammaNetz" for women with mamma carcinoma as a whole and against the background of the potential for innovation and improvement of case management on the one hand as well as the existence of only few empirical data otherwise, the present survey of members of a trans-sectoral network of the service centre was accomplished. Medical and non-medical networking partners of the service centre (N=168) were questioned by regular mail about different aspects of the cooperation. Identical items in both surveys were compared. The return rate for the medical networking partners is about 59% (n=35), whereby only medical network partners in private practice participated in the survey. For the non-medical networking partners about 60% (n=66) participated. Medical networking partners assess the cooperation with the service centre in reference to the exchange of information slightly more positively (66%) than the non-medical networking partners (59%). Medical networking partners are in significantly more frequent contact with the service centre and see in the cooperation significantly more advantages for their own office/facility (each with p=0.001) than non-medical networking partners. Overall the results suggest that medical as well as non-medical networking

    Full Text Available BACKGROUND It is well known that the provision of public childcare plays an important role for women labour force participation and its availability varies tremendously across countries. In many countries, informal childcare is also important and typically provided by the grandparents, but its role on mothers' employment is not yet well understood. Understanding the relationship between labour supply decisions and grandparental childcare is complex. While the provision of grandparental childcare is clearly a function of the social and institutional context of a country, it also depends on family preferences, which are typically unobserved in surveys. OBJECTIVE We analyze the role of informal childcare provided by grandparents on mothers' labour force participation keeping unobserved preferences into account. METHODS Bivariate probit models with instrumental variables are estimated on data from seven countries (Bulgaria, France, Georgia, Germany, Hungary, Russia and The Netherlands drawn from the Generations and Gender Survey. RESULTS We find that only in some countries mothers' employment is positively and significantly associated with grandparents providing childcare. In other countries, once we control for unobserved preferences, we do not find this effect. CONCLUSIONS The role of grandparents is an important element to reconcile work and family for women in some countries. Our results show the importance of considering family preferences and country differences when studying the relationship between grandparental childcare and mothers' labour supply. COMMENTS Our results are consistent with previous research on this topic. However, differently from previous studies, we conduct separate analyses by country and show that the effect of grandparental childcare varies considerably. The fact that we also include in the analyses Bulgaria, Hungary, Russia and Georgia is an important novelty as there are no studies on this issue

    Full Text Available Fuzzy time series methods based on the fuzzy set theory proposed by Zadeh (1965 was first introduced by Song and Chissom (1993. Since fuzzy time series methods do not have the assumptions that traditional time series do and have effective forecasting performance, the interest on fuzzy time series approaches is increasing rapidly. Fuzzy time series methods have been used in almost all areas, such as environmental science, economy and finance. The concepts of labour force participation and unemployment have great importance in terms of both the economy and sociology of countries. For this reason there are many studies on their forecasting. In this study, we aim to forecast the labour force participation and unemployment rate in Poland and Turkey using different fuzzy time series methods.

    2011-01-01

    We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z ~ 1.6 from the Hubble Space Telescope Cluster Supernova Survey. In observations spanning 189 orbits with the Advanced Camera for Surveys we discovered 29 SNe, of which approximately 20 are SNe Ia. Twelve of these SNe Ia are located in the foregrounds and backgrounds of the clusters targeted in the survey. Using these new data, we derive the volumetric SN Ia rate in four broad redshift bins, finding results consistent with previous measurements at z > 1 and strengthening the case for a SN Ia rate that is equal to or greater than ~0.6 x 10^-4/yr/Mpc^3 at z ~ 1 and flattening out at higher redshift. We provide SN candidates and efficiency calculations in a form that makes it easy to rebin and combine these results with other measurements for increased statistics. Finally, we compare the assumptions about host-galaxy dust extinction used in different high-redshift rate measurements, finding that different assumptions may induce sig...

    The Canada-France-Hawaii Telescope Supernova Legacy Survey (SNLS) has created a large homogeneous database of intermediate redshift (0.2 < z < 1.0) type Ia supernovae (SNe Ia). The SNLS team has shown that correlations exist between SN Ia rates, properties, and host galaxy star formation rates. The SNLS SN Ia database has now been combined with a photometric redshift galaxy catalog and an optical galaxy cluster catalog to investigate the possible influence of galaxy clustering on the SN Ia rate, over and above the expected effect due to the dependence of SFR on clustering through the morphology-density relation. We identify three cluster SNe Ia, plus three additional possible cluster SNe Ia, and find the SN Ia rate per unit mass in clusters at intermediate redshifts is consistent with the rate per unit mass in field early-type galaxies and the SN Ia cluster rate from low redshift cluster targeted surveys. We also find the number of SNe Ia in cluster environments to be within a factor of two of expectati...

    Transect surveys without some means of estimating detection probabilities generate population size indices prone to bias because survey conditions differ in time and space. Knowing what causes such bias can help guide the collection of relevant survey covariates, correct the survey data, anticipate situations where bias might be unacceptably large, and elucidate the ecology of target species. We used negative binomial regression to evaluate confounding variables for gecko (primarily Hemidactylus frenatus and Lepidodactylus lugubris) counts on 220-m-long transects surveyed at night, primarily for snakes, on 9,475 occasions. Searchers differed in gecko detection rates by up to a factor of six. The worst and best headlamps differed by a factor of at least two. Strong winds had a negative effect potentially as large as those of searchers or headlamps. More geckos were seen during wet weather conditions, but the effect size was small. Compared with a detection nadir during waxing gibbous (nearly full) moons above the horizon, we saw 28% more geckos during waning crescent moons below the horizon. A sine function suggested that we saw 24% more geckos at the end of the wet season than at the end of the dry season. Fluctuations on a longer timescale also were verified. Disturbingly, corrected data exhibited strong short-term fluctuations that covariates apparently failed to capture. Although some biases can be addressed with measured covariates, others will be difficult to eliminate as a significant source of error in longterm monitoring programs.

    To examine the associations between resilience, community belonging, and social participation, and the moderating effect of resilience on the association between community belonging and social participation among community-dwelling older adults. Cross-sectional; secondary analyses of the Eastern Townships Population Health Survey. Community. A sample (N=4541) of women (n=2485) and men (n=2056) aged ≥60 years was randomly selected according to area. Most participants had resilience were collected by phone interviewer-administered questionnaire. A social participation scale measured frequency of participation in 8 community activities. A 4-point Likert scale ranging from "very strong" to "very weak" estimated sense of belonging to the local community. Social participation and sense of belonging questions came from Statistics Canada surveys. Resilience was assessed with the 10-item Connor-Davidson Resilience Scale, capturing the ability to cope with adversity. Controlling for age, education, and psychological distress, greater resilience and community belonging were associated with greater social participation among women (R(2)=.13; Presilience, especially in men. Greater community belonging further enhanced social participation, especially among women (P=.03) and men (Presilience (moderator effect). Resilience moderates the association between community belonging and social participation among community-dwelling older women and, especially, men. Interventions targeting social participation should consider the potential impact of resilience on improving community belonging. Future studies should investigate why resilience moderates associations between community belonging and social participation, and how to enhance resilience among older adults. Crown Copyright © 2017.

    When estimating population level changes in health indicators, the declining response rate, especially if also the characteristics of non-respondents are changing may bias the outcome. There is evidence that survey response rates are declining in many countries. It is also known that respondents and non-respondents differ in their socio-economic and demographic status as well as in their health and health behaviours. There is no information about the changes in the differences between respondents and non-respondents over time. Our purpose was to investigate the changes over time in the differences between respondents and non-respondents in respect to their sex, age, marital status and educational level. The data from the Finnish Adult Health Behaviour Survey (1978-2002) was used. The response rate declined over the past 25 years for both men and women in all age groups. The decline was faster among men than women, and also faster in younger age groups than older age groups. There is a marked difference in the response rate between married and non-married persons but it did not change over time. Also the response rate between different educational levels differed for both men and women, and this difference increased over the years. The declining response rate and at the same time occurring change in the non-respondent characteristics will decrease the representativeness of the results, limit the comparability of the results with other surveys, increase the bias of the trend estimates and limit the comparability of the results between population groups.

  5. Mobile natural gas leak surveys indicate that two utilities have high false negative rates

    In the distribution systems that carry natural gas to consumers, leaks need to be discovered for safety reasons and to reduce greenhouse gas emissions. However, few utilities have adopted newer laser-based technologies that have greater sensitivity and precision, and instead rely on "industry standard" equipment that is far less sensitive. In partnership with the Environmental Defense Fund and Google, we mapped natural gas leaks in the domains of two anonymous utilities (Utility "A" and "B") using high sensitivity Picarro methane analyzers in Google Street View Cars. Surprisingly, when we shared these results with utilities, their survey crews were unable to find most of the leaks that our survey indicated (84% in A and 80% in B). To investigate this phenomenon, our team visited a subset of the leaks in each utility domain (n=32 in A and n=30 in B), and worked alongside utility surveyors to search the leak indication area, using a Los Gatos Research ultraportable methane analyzer to pinpoint leak locations. We found evidence of natural gas leaks at 69% and 68% of the locations in Utilities A and B respectively where survey crews had found nothing. We describe this as a "false negative" rate for the utility because the utility survey falsely indicated that there was no leak at these locations. Of these false negatives, 7% (n=2 of 32 in A, n=2 of 30 in B) were determined to be Grade 1 leaks requiring immediate repair due to high safety risk. Instrument sensitivity appears to explain some of the false negative rates. In particular, use of some industry standard equipment appears to have created a false sense of confidence among utility surveyors that leaks were not present. However, there was also evidence of communication failures and that surveyors did not use optimal approaches in their search. Based on these findings, we suggest that: 1) mobile deployment of high-precision methane analyzers can help find more natural gas leaks, and 2) use of some hand-held survey

    We evaluated double-observer methods for aerial surveys as a means to adjust counts of waterfowl for incomplete detection. We conducted our study in eastern Canada and the northeast United States utilizing 3 aerial-survey crews flying 3 different types of fixed-wing aircraft. We reconciled counts of front- and rear-seat observers immediately following an observation by the rear-seat observer (i.e., on-the-fly reconciliation). We evaluated 6 a priori models containing a combination of several factors thought to influence detection probability including observer, seat position, aircraft type, and group size. We analyzed data for American black ducks (Anas rubripes) and mallards (A. platyrhynchos), which are among the most abundant duck species in this region. The best-supported model for both black ducks and mallards included observer effects. Sample sizes of black ducks were sufficient to estimate observer-specific detection rates for each crew. Estimated detection rates for black ducks were 0.62 (SE = 0.10), 0.63 (SE = 0.06), and 0.74 (SE = 0.07) for pilot-observers, 0.61 (SE = 0.08), 0.62 (SE = 0.06), and 0.81 (SE = 0.07) for other front-seat observers, and 0.43 (SE = 0.05), 0.58 (SE = 0.06), and 0.73 (SE = 0.04) for rear-seat observers. For mallards, sample sizes were adequate to generate stable maximum-likelihood estimates of observer-specific detection rates for only one aerial crew. Estimated observer-specific detection rates for that crew were 0.84 (SE = 0.04) for the pilot-observer, 0.74 (SE = 0.05) for the other front-seat observer, and 0.47 (SE = 0.03) for the rear-seat observer. Estimated observer detection rates were confounded by the position of the seat occupied by an observer, because observers did not switch seats, and by land-cover because vegetation and landform varied among crew areas. Double-observer methods with on-the-fly reconciliation, although not without challenges, offer one viable option to account for detection bias in aerial waterfowl

    Full Text Available Occupation is key in socioeconomic research. As in other survey modes, most web surveys use an open-ended question for occupation, though the absence of interviewers elicits unidentifiable or aggregated responses. Unlike other modes, web surveys can use a search tree with an occupation database. They are hardly ever used, but this may change due to technical advancements. This article evaluates a three-step search tree with 1,700 occupational titles, used in the 2010 multilingual WageIndicator web survey for UK, Belgium and Netherlands (22,990 observations. Dropout rates are high; in Step 1 due to unemployed respondents judging the question not to be adequate, and in Step 3 due to search tree item length. Median response times are substantial due to search tree item length, dropout in the next step and invalid occupations ticked. Overall the validity of the occupation data is rather good, 1.7-7.5% of the respondents completing the search tree have ticked an invalid occupation.

    To assess whether comprehensive medication reviews conducted by clinical pharmacists as part of a healthcare team reduce drug-related hospital readmission rates among people with dementia or cognitive impairment. This randomized controlled trial was carried out between January 9, 2012, and December 2, 2014. Patients aged ≥65 years with dementia or cognitive impairment admitted to three wards at two hospitals located in Northern Sweden were included. Of the 473 deemed eligible for participation, 230 were randomized to intervention and 230 to control group by block randomization. The primary outcome, risk of drug-related hospital readmissions, was assessed at 180 days of follow-up by intention-to-treat analysis. During the 180 days of follow-up, 18.9% (40/212) of patients in the intervention group and 23.0% (50/217) of those in the control group were readmitted for drug-related reasons (HR = 0.80, 95% CI = 0.53-1.21, p = 0.28, univariable Cox regression). Heart failure was significantly more common in the intervention group. After adjustment for heart failure as a potential confounder and an interaction term, multiple Cox regression analysis indicated that pharmacist participation significantly reduced the risk of drug-related readmissions (HR = 0.49, 95% CI = 0.27-0.90, p = 0.02). A post-hoc analysis showed a significantly reduced risk of 30-day readmissions due to drug-related problems in the total sample (without adjustment for heart failure). Participation of clinical pharmacists in healthcare team conducting comprehensive medication reviews did not significantly reduce the risk of drug-related readmissions in patients with dementia or cognitive impairment; however, post-hoc and subgroup analyses indicated significant effects favoring the intervention. More research is needed. Clinical trials NCT01504672.

    A survey of the suicidal mortality rates in two cities and six districts in Sichuan province was carried out from 1980 to 1988 by the authors. The average suicidal mortality rate (ASMR) in these districts from 1980 to 1988 was 15.5/10(5), and the population and suicidal mortality rate positively correlated, r = 0.53. The ASMR in the male was 14.9/10(5), in the female 17.1/10(5), in the urban area 9.4/10(5), in the rural area 21/10(5), and the ASMR in the urban area was higher than that in the rural area (P < 0.05). The peak age of suicidal mortality was around twenty years.

    @@ The paper of Shen et al., entitled "Surveying of the deformed terraces and crust shortening rate in the northwest Tarim Basin", was published in Chinese Science Bulletin (Vol. 46, No. 12)[1]. Shen et al. found the deformation of Late Pleistocene to Holocene terraces of the Boguzi River across the Artushi Anticline in the northwest Tarim Basin close to the Pamir, and made level survey and differential GPS measurement, which is of great importance to geodynamics for research on the coupling of Tianshan Mountains uplifting and Tarim Basin depression. But their understanding to the deformation mechanics of terraces and the calculation methods of crustal shortening are open to discussion. Therefore, we discuss it with Shen Jun et al.

    This paper examines rates of self-reported driving under the influence (DUI) of alcohol and 12-month and lifetime DUI arrest rates among Mexican Americans, Puerto Ricans, Cuban Americans and South/Central Americans in the U.S. population. Using a multistage cluster sample design, a total of 5224 individuals 18 years of age and older were selected from the household population in five metropolitan areas of the U.S.: Miami, New York, Philadelphia, Houston and Los Angeles. The survey weighted response rate was 76%. Among men, 21% of Mexican Americans, 19.9% of South/Central Americans, 11.6% of Puerto Ricans and 6.9% of Cuban Americans reported DUI. Rates were lower among women, ranging from 9.7% for Mexican Americans to 1.3% for Cuban Americans. Mexican American men had the highest 12-month arrest rate (1.6%) and the highest lifetime arrest rate (11.2%). Drinkers who reported DUI were heavier drinkers than those not reporting DUI according to a variety of indicators. However, most DUI incidents involved non-alcohol-dependent drivers. Mexican Americans and South Central/Americans, men, younger drivers, those with less than high school education, those with higher income and higher alcohol consumption were more likely to report DUI and DUI arrests. These findings show that Hispanic national groups in the U.S. are diverse regarding drinking and DUI-related experiences.

    This final rule updates the Home Health Prospective Payment System (HH PPS) rates, including the national standardized 60-day episode rates, the national per-visit rates, the low-utilization payment amount (LUPA), the non-routine medical supplies (NRS) conversion factor, and outlier payments under the Medicare prospective payment system for home health agencies effective January 1, 2013. This rule also establishes requirements for the Home Health and Hospice quality reporting programs. This final rule will also establish requirements for unannounced, standard and extended surveys of home health agencies (HHAs) and sets forth alternative sanctions that could be imposed instead of, or in addition to, termination of the HHA's participation in the Medicare program, which could remain in effect up to a maximum of 6 months, until an HHA achieves compliance with the HHA Conditions of Participation (CoPs) or until the HHA's provider agreement is terminated.

    We present a measurement of the volumetric Type Ia supernova (SN Ia) rate (SNR_Ia) as a function of redshift for the first four years of data from the Canada-France-Hawaii Telescope (CFHT) Supernova Legacy Survey (SNLS). This analysis includes 286 spectroscopically confirmed and more than 400 additional photometrically identified SNe Ia within the redshift range 0.1rates is slightly shallower than that of the cosmic star-formation history over the same redshift range. We combine the SNLS rate measurements with those from other surveys that complement the SNLS redshift range, and fit various simple SN Ia delay-time distribution (DTD) models to the combined data. A simple power-law model for the DTD (i.e., proportional to t^-beta) yields values from beta=0.98+/-0.05 to beta=1.15+/-0.08 depending on the parameterization of t...

    Introduction: Knowledge on epidemiology of the disease in the contemporary world will help to develop appropriate strategies to curtail the transmission during an outbreak. This study was carried out during an outbreak of conjunctivitis in selected areas of Puducherry, South India, to assess the attack rate of conjunctivitis, identify factors associated with developing conjunctivitis and calculate household secondary attack rate (HSAR) of conjunctivitis and its correlates. Methodology: During December 2014, a community-based survey was conducted in a selected urban and rural area in Puducherry, South India. Simple random sampling was used to select primary sampling units and systematic sampling to select households. All individuals in the selected households were studied. A questionnaire was used to obtain data on sociodemographic characteristics, conjunctivitis during September-November, 2014, and number of household contacts who developed conjunctivitis within 7 days of index case. The attack rate and HSAR of conjunctivitis was expressed as percentage. Multivariate logistic regression was used to find factors independently associated with developing conjunctivitis and also 100% HSAR. Results: Of 3193 study participants from 772 households, 509 (15.9%, 95% confidence interval 14.7-17.2%) had an attack of conjunctivitis during the reference period. Of the 772 households, 218 (28.2%) had at least one case of conjunctivitis. Of 218 households, 33 (15.1%) households had 100% HSAR. Lower age, not being unemployed, low socioeconomic status, and residing in rural area were independently associated with developing conjunctivitis. Index case being male and living in a household with ≥5 members were independently associated with 100% HSAR. Conclusion: In the outbreak under study, more than one-fourth of households had at least one case of conjunctivitis and about one in every six individuals had an attack of conjunctivitis.

    Full Text Available The objective of this study was to investigate the self-care behaviors among hypertensive patients in primary care. A cross-sectional survey, with 318 hypertensive patients, was conducted in a rural area in Beijing, China, in 2012. Participants were mainly recruited from a community health clinic and completed questionnaires assessing their self-care behaviors, including data on adherence to a prescribed medication regimen, low-salt diet intake, smoking habits, alcohol consumption, blood pressure monitoring, and physical exercise. The logistic regression model was used for the analysis of any association between self-care behaviors and age, gender, duration of hypertension, self-rated health, marital status, education level, diabetes status, or body mass index. Subjects that adhered to their medication schedule were more likely to have hypertension for a long duration (OR, 3.44; 95% CI 1.99–5.97. Older participants (OR, 1.80; 95% CI 1.08–2.99 were more likely to monitor their blood pressure. Subjects who did not partake in physical exercise were more likely to be men, although the difference between genders was not significant (OR, 0.60; 95% CI 0.36–1.01. Patients with shorter history of hypertension, younger and being males have lower self-care behaviors. Primary care providers and public health practitioner should pay more attention to patients recently diagnosed with hypertension as well as younger male patients.

    While there is considerable research on medical workforce supply trends, there is little research examining the determinants of labour supply decisions for the medical workforce. The "Medicine in Australia: Balancing Employment and Life (MABEL)" study investigates workforce participation patterns and their determinants using a longitudinal survey of Australian doctors. It aims to generate evidence to support developing effective policy responses to workforce issues such as shortages and maldistribution. This paper describes the study protocol and baseline cohort, including an analysis of response rates and response bias. MABEL is a prospective cohort study. All Australian doctors undertaking clinical work in 2008 (n = 54,750) were invited to participate, and annual waves of data collections will be undertaken until at least 2011. Data are collected by paper or optional online version of a questionnaire, with content tailored to four sub-groups of clinicians: general practitioners, specialists, specialists in training, and hospital non-specialists. In the baseline wave, data were collected on: job satisfaction, attitudes to work and intentions to quit or change hours worked; a discrete choice experiment examining preferences and trade-offs for different types of jobs; work setting; workload; finances; geographic location; demographics; and family circumstances. The baseline cohort includes 10,498 Australian doctors, representing an overall response rate of 19.36%. This includes 3,906 general practitioners, 4,596 specialists, 1,072 specialists in training, and 924 hospital non-specialists. Respondents were more likely to be younger, female, and to come from non-metropolitan areas, the latter partly reflecting the effect of a financial incentive on response for doctors in remote and rural areas. Specialists and specialists in training were more likely to respond, whilst hospital non-specialists were less likely to respond. The distribution of hours worked was similar

    We have combined the large SN Ia database of the Canada-France-Hawaii Telescope Supernova Legacy Survey and catalogs of galaxies with photometric redshifts, VLA 1.4 GHz radio sources, and Spitzer infrared sources. We present eight SNe Ia in early-type host galaxies which have counterparts in the radio and infrared source catalogs. We find the SN Ia rate in subsets of radio and infrared early-type galaxies is ~1-5 times the rate in all early-type galaxies, and that any enhancement is always <~ 2 sigma. Rates in these subsets are consistent with predictions of the two component "A+B" SN Ia rate model. Since infrared properties of radio SN Ia hosts indicate dust obscured star formation, we incorporate infrared star formation rates into the "A+B" model. We also show the properties of SNe Ia in radio and infrared galaxies suggest the hosts contain dust and support a continuum of delay time distributions for SNe Ia, although other delay time distributions cannot be ruled out based on our data.

    Issue addressed: Workplaces are promising settings for health promotion, yet employee participation in workplace health promotion (WHP) activities is often low or variable. This study explored facilitating factors and barriers associated with participation in WHP activities that formed part of a comprehensive WHP initiative run within the Tasmanian State Service (TSS) between 2009 and 2013.Methods: TSS employee (n=3228) completed surveys in 2013. Data included sociodemographic characteristics, employee-perceived availability of WHP activities, employee-reported participation in WHP activities, and facilitators and barriers to participation. Ordinal log-link regression was used in cross-sectional analyses.Results: Significant associations were found for all facilitating factors and participation. Respondents who felt their organisation placed a high priority on WHP, who believed that management supported participation or that the activities could improve their health were more likely to participate. Time- and health-related barriers were associated with participation in fewer activities. All associations were independent of age, sex, work schedule and employee-perceived availability of programs. Part-time and shift-work patterns, and location of activities were additionally identified barriers.Conclusion: Facilitating factors relating to implementation, peer and environmental support, were associated with participation in more types of activities, time- and health-related barriers were associated with less participation.So what?: Large and diverse organisations should ensure WHP efforts have manager support and adopt flexible approaches to maximise employee engagement.

    Young adults who had previously participated in a longitudinal survey of youth were sent a questionnaire. They were randomly assigned to receive a $20 prepayment, a $20 postpayment, or a $25 postpayment for participation in the latest survey. Those in the large incentive condition were 7 percentage points more likely to return a survey than those in the smaller, postpayment group. Prepayment had a smaller, less reliable effect. Effects of incentive magnitude and timing were consistent at each month of the study period; only better high school grades distinguished early responders from late responders. Nonresponders had characteristics suggestive of low social conformity and were more likely than responders to be African American and male and have low SES. The discussion centers on motivations for participating in research and differences in the incentives likely to promote continued response versus initial study enrollment.

    We present measurements of the rates of high-redshift Type Ia supernovae derived from the Subaru/XMM-Newton Deep Survey (SXDS). We carried out repeat deep imaging observations with Suprime-Cam on the Subaru Telescope, and detected 1040 variable objects over 0.918 deg$^2$ in the Subaru/XMM-Newton Deep Field. From the imaging observations, light curves in the observed $i'$-band are constructed for all objects, and we fit the observed light curves with template light curves. Out of the 1040 variable objects detected by the SXDS, 39 objects over the redshift range $0.2 < z < 1.4$ are classified as Type Ia supernovae using the light curves. These are among the most distant SN Ia rate measurements to date. We find that the Type Ia supernova rate increase up to $z \\sim 0.8$ and may then flatten at higher redshift. The rates can be fitted by a simple power law, $r_V(z)=r_0(1+z)^\\alpha$ with $r_0=0.20^{+0.52}_{-0.16}$(stat.)$^{+0.26}_{-0.07}$(syst.)$\\times 10^{-4} {\\rm yr}^{-1}{\\rm Mpc}^{-3}$, and $\\alpha=2.04^{...

    Full Text Available Abstract Background Indoor air pollution (IAP from solid fuels is a serious health problem in low-income countries that can be alleviated using improved stoves. Although women are the principal users, few studies have investigated the self-assessed impact of the stoves on their health and lives. Methods This study was conducted in rural highland Guatemala, involving 89 intervention and 80 control Mayan Indian young women (mean 27.8 years, SD 7.2. Outcomes were assessed after approximately 18 months use of the new stove. Our objectives were to compare self-rated health and change in health among women participating in a randomised control trial comparing a chimney stove with an open fire, to describe impacts on women's daily lives and their perceptions of how reduced kitchen smoke affects their own and their children's health. Results On intention-to-treat analysis, 52.8% of intervention women reported improvement in health, compared to 23.8% of control women (p Conclusion Women's perception of their health was improved, but although smoke reduction was valued, this was linked mainly with alleviation of non-respiratory symptoms like eye discomfort and headache. More focus on such symptoms may help in promoting demand for improved stoves and cleaner fuels, but education about more severe consequences of IAP exposure is also required.

    In the late nineteenth and early twentieth centuries, a number of European expeditions traveled to the region of Lake Rudolf, now largely in northern Kenya. Although diverse in intent, many of these were undertaken in the interests of furthering colonial territorial claims. In 1900-1901, Major Herbert Henry Austin led a British expedition down to the lake from Khartoum in the north. Of the 62 African, Arab, and European members of this expedition, only 18 (29 %) arrived at its final destination at Lake Baringo in Kenya. Because of a confluence of adverse climatic, social, and political conditions, the expedition ran short of food supplies when it arrived at the northern end of the lake in April 1901. For the next 4 months, the members of the expedition struggled down the west side of the lake and beyond. The greatest mortality (91 %) occurred among the 32 African transport drivers who were the most marginally nourished at the outset of the trip. The lowest mortality among the Africans on the expedition (15 %) occurred among the members of the Tenth Sudanese Rifles Battalion, who had an excellent nutritional status at the start of the expedition. Major Austin himself suffered from severe scurvy with retinal hemorrhages which left him partially blind in his right eye. An analysis of the mortality rates among the groups that participated in this expedition was undertaken. This revealed that poor nutritional status at the start of the trip was predictive of death from starvation.

    The initial distribution of spin rates of massive stars is a fingerprint of their elusive formation process. It also sets a key initial condition for stellar evolution and is thus an important ingredient in stellar population synthesis. So far, most studies have focused on single stars. Most O stars are however found in multiple systems. By establishing the spin-rate distribution of a sizeable sample of O-type spectroscopic binaries and by comparing the distributions of binary sub-populations with one another as well as with that of presumed single stars in the same region, we aim to constrain the initial spin distribution of O stars in binaries, and to identify signatures of the physical mechanisms that affect the evolution of the massive stars spin rates. We use ground-based optical spectroscopy obtained in the framework of the VLT-FLAMES Tarantula Survey (VFTS) to establish the projected equatorial rotational velocities (\\vrot) for components of 114 spectroscopic binaries in 30 Doradus.

We observed four one-square degree fields with a typical temporal frequency of ~ 4 observer-frame days over time spans of from 158 to 211 days per season for each field, with breaks during full moon. We used 8-10 meter-class telescopes for spectroscopic followup to confirm our candidates and determine their redshifts.

    Supernova rates are directly coupled to high mass stellar birth and evolution. As such, they are one of the few direct measures of the history of cosmic stellar evolution. In this paper we describe an probabilistic technique for identifying supernovae within spectroscopic samples of galaxies. We present a study of 52 type Ia supernovae ranging in age from -14 days to +40 days extracted from a parent sample of \\simeq 50,000 spectra from the SDSS DR5. We find a Supernova Rate (SNR) of 0.472^{+0.048}_{-0.039}(Systematic)^{+0.081}_{-0.071}(Statistical)SNu at a redshift of = 0.1. This value is higher than other values at low redshift at the 1{\\sigma}, but is consistent at the 3{\\sigma} level. The 52 supernova candidates used in this study comprise the third largest sample of supernovae used in a type Ia rate determination to date. In this paper we demonstrate the potential for the described approach for detecting supernovae in future spectroscopic surveys.

    The impending era of wide-field radio surveys has the potential to revolutionize our understanding of astrophysical transients. Here we evaluate the prospects of a wide range of planned and hypothetical radio surveys using the properties and volumetric rates of known and hypothetical classes of extragalactic synchrotron radio transients (e.g., on- and off-axis gamma-ray bursts [GRB], supernovae, tidal disruption events [TDE], compact object mergers). Utilizing these sources and physically motivated considerations we assess the allowed phase-space of radio luminosity and peak timescale for extragalactic transients. We also include for the first time effects such as redshift evolution of the rates, K-corrections, and non-Euclidean luminosity distance, which affect the detection rates of the most sensitive surveys. The number of detected events is calculated by means of a Monte Carlo method, using the various survey properties (depth, cadence, area) and realistic detection criteria that include a cut on the mini...

    Background Most research on how to enhance response rates in physician surveys has been done using paper surveys. Uncertainties remain regarding how to enhance response rates in Internet-based surveys. Objective To evaluate the impact of a low-cost nonmonetary incentive and paper mail reminders (formal letter and postcard) on response rates in Internet-based physician surveys. Methods We executed a factorial-design randomized experiment while conducting a nationally representative Internet-based physician survey. We invited 3966 physicians (randomly selected from a commercial database of all licensed US physicians) via email to complete an Internet-based survey. We used 2 randomly assigned email messages: one message offered a book upon survey completion, whereas the other did not mention the book but was otherwise identical. All nonrespondents received several email reminders. Some physicians were further assigned at random to receive 1 reminder via paper mail (either a postcard or a letter) or no paper reminder. The primary outcome of this study was the survey response rate. Results Of the 3966 physicians who were invited, 451 (11.4%) responded to at least one survey question and 336 (8.5%) completed the entire survey. Of those who were offered a book, 345/2973 (11.6%) responded compared with 106/993 (10.7%) who were not offered a book (odds ratio 1.10, 95% CI 0.87-1.38, P=.42). Regarding the paper mail reminder, 168/1572 (10.7%) letter recipients, 148/1561 (9.5%) postcard recipients, and 69/767 (9.0%) email-only recipients responded (P=.35). The response rate for those receiving letters or postcards was similar (odds ratio 1.14, 95% CI 0.91-1.44, P=.26). Conclusions Offering a modest nonmonetary incentive and sending a paper reminder did not improve survey response rate. Further research on how to enhance response rates in Internet-based physician surveys is needed. PMID:27637296

    To investigate the parental acceptance rate to behavior management techniques (BMT) used in pediatric dentistry. Two hundred and eighty-five subjects (mother or father) were included in this survey. Five behavior management techniques including (1)tell-show-do; (2)voice control; (3)passive restraint; (4)sedation; (5) general anesthesia commonly used in pediatric dentistry were explained to the parents and then filled the questionnaires by either of the parents, including the parental age, gender, educational level and income, The answerer rated their acceptance of each technique using a visual analogue scale (VAS), a continuous scale ranging from 0 to 100mm. The left end represented "completely acceptable" and the right end represented "completely unacceptable". The subjects were instructed to rate the acceptability of each technique by placing a mark on the VAS response line. The acceptability rating of each technique by the subject was determined by measuring the distance between VAS line from the left end to the mark. SPSS10.0 software was used for statistical analysis. VAS measurements were analyzed using a factorial analysis of variance (ANOVA). Student's t test was used to analyze the difference between the acceptance rates for different gender of the answerers. The correlation between independent variables consisted of parental gender, education level, income and behavior management techniques were analyzed using Spearman correlation test. The order of decreasing acceptance rate was as follows, tell-show-do, voice control, sedation, general anesthesia and passive restraint. The difference between each of them was statistically significant (F=215.2,Panesthesia by Spearman correlation analysis (P<0.01). The acceptance rate of tell-show-do and passive restraint were related to parental gender. According to Students's t test, female tended to accept tell-show-do more than males (P=0.011), nevertheless more males tended to accept passive restraint (P=0.001). No

    This study explored the effects of the diagnosis-related group (DRG)-based prospective payment system (PPS) operated by voluntarily participating organizations on the cesarean section (CS) rates, and analyzed whether the participating health care organizations had similar CS rates despite the varied participation periods. The study sample included delivery claims data from the Korean national health insurance program for the year 2003. Risk factors were identified and used in the adjustment model to distinguish the main reason for CS. Their risk-adjusted CS rates were compared by the reimbursement methods, and the organizations' internal and external environments were controlled. The final risk-adjustment model for the CS rates meets the criteria for an effective model. There were no significant differences of CS rates between providers in the DRG and fee-for-service system after controlling for organizational variables. The CS rates did not vary significantly depending on the providers' DRG participation periods. The results provide evidence that the DRG payment system operated by volunteering health care organizations had no impact on the CS rates, which can lower the quality of care. Although the providers joined the DRG system in different years, there were no differences in the CS rates among the DRG providers. These results support the future expansion of the DRG-based PPS plan to all health care services in Korea.

    Full Text Available Abstract Background The aim of this report is to describe the main characteristics of the design, including response rates, of the Cornella Health Interview Survey Follow-up Study. Methods The original cohort consisted of 2,500 subjects (1,263 women and 1,237 men interviewed as part of the 1994 Cornella Health Interview Study. A record linkage to update the address and vital status of the cohort members was carried out using, first a deterministic method, and secondly a probabilistic one, based on each subject's first name and surnames. Subsequently, we attempted to locate the cohort members to conduct the phone follow-up interviews. A pilot study was carried out to test the overall feasibility and to modify some procedures before the field work began. Results After record linkage, 2,468 (98.7% subjects were successfully traced. Of these, 91 (3.6% were deceased, 259 (10.3% had moved to other towns, and 50 (2.0% had neither renewed their last municipal census documents nor declared having moved. After using different strategies to track and to retain cohort members, we traced 92% of the CHIS participants. From them, 1,605 subjects answered the follow-up questionnaire. Conclusion The computerized record linkage maximized the success of the follow-up that was carried out 7 years after the baseline interview. The pilot study was useful to increase the efficiency in tracing and interviewing the respondents.

    Full Text Available INTRODUCTION: Studies have shown that perceived discrimination has an impact on our physical and mental health. A relevant part of literature has highlighted the influence of discrimination based on race or ethnicity on mental and physical health outcomes. However, the influence of other types of discrimination on health has been understudied. This study is aimed to explore how different types of discrimination are related to our subjective state of health, and so to compare the intensity of these relationships in the European context. METHODS: We have performed a multilevel ordered analysis on the fifth wave of the European Social Survey (ESS 2010. This dataset has 52,458 units at individual level that are grouped in 26 European countries. In this study, the dependent variable is self-rated health (SRH that is analyzed in relationship to ten explanatory variables of perceived discrimination: color or race, nationality, religion, language, ethnic group, age, gender, sexuality, disability and others. RESULTS: The model identifies statistically significant differences in the effect that diverse types of perceived discrimination can generate on the self-rated health of Europeans. Specifically, this study identifies three well-defined types of perceived discrimination that can be related to poor health outcomes: (1 age discrimination; (2 disability discrimination; and (3 sexuality discrimination. In this sense, the effect on self-rated health of perceived discrimination related to aging and disabilities seems to be more relevant than other types of discrimination in the European context with a longer tradition in literature (e.g. ethnic and/or race-based. CONCLUSION: The present study shows that the relationship between perceived discrimination and health inequities in Europe are not random, but systematically distributed depending on factors such as age, sexuality and disabilities. Therefore the future orientation of EU social policies should aim

    Full Text Available Introduction: Farmers are facing with a variety of natural and unnatural risks in agricultural activities, and thus their income is unstable. A wide range of risks such as risks of production, price risk, financial and human risks, influence the income of agricultural products. One of the major risks that farmers faced is the risk of price volatility of agricultural products. Cotton is one of the agricultural products with high real price volatility. Numerous tools for marketing and risk management for agricultural products in the face of price risks are available. Futures and options contracts may be the most important available tools (to reduce price volatility in agricultural products. The purpose of the current study was to look at the possibility of farmers participations in the future and option markets that presented as a means to reduce the cotton prices volatility. The dependent variable for this purpose had four categories and these included: participate in both the market, participation in the future market, participation in the option market and participation in both future and option markets. Materials and Methods: data gathered with interview and completing 200 questionnaires of cotton growers using simple random sampling. Multinomial Logit Regression Model was used for data analysis. Results and Discussion: To measure content validity of the preliminary study the validity of confirmatory factor analysis were used. For calculating reliability, the pre-test done with 30 questionnaires and reliability, coefficient Cronbach alpha was 0.79. The independence of dependent variables categories was confirmed by Hausman test results. The Likelihood ratio and Wald showed these categories are not combinable. Results indicated into period 2014 -2015 and the sample under study, 35% of cotton growers unwilling to participate in future and option markets. Farmers willingness to participate in future and option market was 19% and %21

    Full Text Available Effective community-level chronic disease prevention is critical to population health within developed and developing nations. Pasos Adelante is a preventive intervention that aims to reduce chronic disease risk with evidence of effectiveness in US-Mexico residing, Mexican origin, participants. This intervention and related ones also implemented with community health workers have been shown to improve clinical, behavioral and quality of life indicators; though most evidence is from shorter-term evaluations and/or lack comparison groups. The current study examines the impact of this program using secondary data collected in the community 3–6 years after all participants completed the program. A proportional household survey (N = 708 was used that included 48 respondents who indicated they had participated in Pasos. Using propensity score matching to account for differences in program participants versus other community residents (the program targeted those with diabetes and associated risk factors, 148 natural controls were identified for 37 matched Pasos participants. Testing a range of behavioral and clinical indicators of chronic disease risk, logistic regression models accounting for selection bias showed two significant findings; Pasos participants were more physically active and drank less whole milk. These findings add to the evidence of the effectiveness of Pasos Adalente and related interventions in reducing chronic disease risk in Mexican-origin populations, and illustrate the use of innovative techniques for using secondary, community-level data to complement prior evaluation research.

    We identified voids in the completed VIMOS Public Extragalactic Redshift Survey (VIPERS), using an algorithm based on searching for empty spheres. We measured the cross-correlation between the centres of voids and the complete galaxy catalogue. The cross-correlation function exhibits a clear anisotropy in both VIPERS fields (W1 and W4), which is characteristic of linear redshift space distortions. By measuring the projected cross-correlation and then deprojecting it we are able to estimate the undistorted cross-correlation function. We propose that given a sufficiently well measured cross-correlation function one should be able to measure the linear growth rate of structure by applying a simple linear Gaussian streaming model for the redshift space distortions (RSD). Our study of voids in 306 mock galaxy catalogues mimicking the VIPERS fields would suggest that VIPERS is capable of measuring $\\beta$ with an error of around $25\\%$. Applying our method to the VIPERS data, we find a value for the redshift space ...

    We present Hubble Space Telescope near-IR spectroscopy for 18 galaxy clusters at 1.0 Survey. We use Wide Field Camera 3 grism data to spectroscopically identify Hα emitters in both the cores of galaxy clusters as well as in field galaxies. We find a large cluster-to-cluster scatter in the star formation rates within a projected radius of 500 kpc, and many of our clusters (∼60%) have significant levels of star formation within a projected radius of 200 kpc. A stacking analysis reveals that dust reddening in these star-forming galaxies is positively correlated with stellar mass and may be higher in the field than the cluster at a fixed stellar mass. This may indicate a lower amount of gas in star-forming cluster galaxies than in the field population. Also, Hα equivalent widths of star-forming galaxies in the cluster environment are still suppressed below the level of the field. This suppression is most significant for lower mass galaxies (log M {sub *} < 10.0 M {sub ☉}). We therefore conclude that environmental effects are still important at 1.0

    To evaluate the extent to which stillbirths affect international comparisons of preterm birth rates in low- and middle-income countries. Secondary analysis of a multi-country cross-sectional study. 29 countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health. 258 215 singleton deliveries in 286 hospitals. We describe how inclusion or exclusion of stillbirth affect rates of preterm births in 29 countries. Preterm delivery. In all countries, preterm birth rates were substantially lower when based on live births only, than when based on total births. However, the increase in preterm birth rates with inclusion of stillbirths was substantially higher in low Human Development Index (HDI) countries [median 18.2%, interquartile range (17.2-34.6%)] compared with medium (4.3%, 3.0-6.7%), and high-HDI countries (4.8%, 4.4-5.5%). Inclusion of stillbirths leads to higher estimates of preterm birth rate in all countries, with a disproportionately large effect in low-HDI countries. Preterm birth rates based on live births alone do not accurately reflect international disparities in perinatal health; thus improved registration and reporting of stillbirths are necessary. Inclusion of stillbirths increases preterm birth rates estimates, especially in low-HDI countries. © 2017 World Health Organization, licensed by John Wiley & Sons Ltd on behalf of Royal College of Obstetricians and Gynaecologists.

  9. The dark energy survey Y1 supernova search: Survey strategy compared to forecasts and the photometric type Is SN volumetric rate

    Science.gov (United States)

    Fischer, John Arthur

    For 70 years, the physics community operated under the assumption that the expansion of the Universe must be slowing due to gravitational attraction. Then, in 1998, two teams of scientists used Type Ia supernovae to discover that cosmic expansion was actually acceler- ating due to a mysterious "dark energy." As a result, Type Ia supernovae have become the most cosmologically important transient events in the last 20 years, with a large amount of effort going into their discovery as well as understanding their progenitor systems. One such probe for understanding Type Ia supernovae is to use rate measurements to de- termine the time delay between star formation and supernova explosion. For the last 30 years, the discovery of individual Type Ia supernova events has been accelerating. How- ever, those discoveries were happening in time-domain surveys that probed only a portion of the redshift range where expansion was impacted by dark energy. The Dark Energy Survey (DES) is the first project in the "next generation" of time-domain surveys that will discovery thousands of Type Ia supernovae out to a redshift of 1.2 (where dark energy be- comes subdominant) and DES will have better systematic uncertainties over that redshift range than any survey to date. In order to gauge the discovery effectiveness of this survey, we will use the first season's 469 photometrically typed supernovee and compare it with simulations in order to update the full survey Type Ia projections from 3500 to 2250. We will then use 165 of the 469 supernovae out to a redshift of 0.6 to measure the supernovae rate both as a function of comoving volume and of the star formation rate as it evolves with redshift. We find the most statistically significant prompt fraction of any survey to date (with a 3.9? prompt fraction detection). We will also reinforce the already existing tension in the measurement of the delayed fraction between high (z > 1.2) and low red- shift rate measurements, where we find no

    Processes of social opinion formation might be dominated by a set of closely connected agents who constitute the cohesive `core' of a network and have a higher influence on the overall outcome of the process than those agents in the more sparsely connected `periphery'. Here we explore whether such a perspective could shed light on the dynamics of a well known economic sentiment index. To this end, we hypothesize that the respondents of the survey under investigation form a core-periphery network, and we identify those agents that define the core (in a discrete setting) or the proximity of each agent to the core (in a continuous setting). As it turns out, there is significant correlation between the so identified cores of different survey questions. Both the discrete and the continuous cores allow an almost perfect replication of the original series with a reduced data set of core members or weighted entries according to core proximity. Using a monthly time series on industrial production in Germany, we also compared experts' predictions with the real economic development. The core members identified in the discrete setting showed significantly better prediction capabilities than those agents assigned to the periphery of the network.

    Given that many astronomers now participate in large international scientific collaborations, it is important to examine whether these structures foster a healthy scientific climate that is inclusive and diverse. The Committee on the Participation of Women in the Sloan Digital Sky Survey (CPWS) was formed to evaluate the climate and demographics within the SDSS collaboration and to make recommendations for how best to establish the scientific and technical leadership team for SDSS-IV. Building on the work described in Lundgren et al. (2015), the CPWS conducted a demographic survey in Spring 2015 that included questions about career and leadership status, racial / ethnic identity, gender identity, identification with the LGBT community, disability, partnership status, and level of parental education. For example, 71% of survey respondents identify as male and 81% do not identify as a racial or ethnic minority at their current institution. This reflects the under-representation of women and men from minority groups (e.g., people of color in the United States) and women from majority groups (e.g., white women in the United States) in the field of astronomy. We have focused our analysis on the representation of scientists from these groups among the SDSS-IV leadership and the full collaboration. Our goal is to use these quantitative data to track the demographics of SDSS-IV membership and leadership over time as we work to assess and improve the climate of SDSS-IV.

    Background Some recent molecular epidemiology studies of the effects of genetic and environmental factors on human health have required the enrollment of more than 100 000 participants and the involvement of regional study offices across the country. Although regional study office investigators play a critical role in these studies, including the acquisition of funds, this role is rarely discussed. Methods We first differentiated the functions of the regional and central study offices. We then investigated the minimum number of items required and approximate cost of a molecular epidemiology study enrolling 7400 participants from a model region with a population of 100 000 for a 4-year baseline survey using a standard protocol developed based on the protocol of Japan Public Health Center-based Prospective Study for the Next Generation. Results The functions of the regional study office were identified, and individual expenses were itemized. The total cost of the 4-year baseline survey was 153 million yen, excluding consumption tax. Accounting difficulties in conducting the survey were clarified. Conclusions We investigated a standardized example of the tasks and total actual costs of a regional study office. Our approach is easy to utilize and will help improve the management of regional study offices in future molecular epidemiology studies. PMID:27001116

    Full Text Available We aimed to examine factors associated with untreated diabetes in a nationally representative sample of the Japanese population.We pooled data from the Japanese National Health and Nutrition Survey from 2005 to 2009 (n = 20,496. Individuals aged 20 years and older were included in the analysis. We classified participants as having diabetes if they had HbA1c levels ≥6.5% (≥48 mmol/mol. People with diabetes who self-reported that they were not currently receiving diabetic treatment were considered to be untreated. We conducted a multinomial logistic regression analysis to determine factors associated with untreated diabetes relative to non-diabetic individuals.Of 20,496 participants who were included in the analysis, untreated diabetes was present in 748 (3.6%. Among participants with untreated diabetes, 48.3% were previously diagnosed with diabetes, and 46.5% had HbA1c levels ≥7.0% (≥53 mmol/mol. Participants with untreated diabetes were significantly more likely than non-diabetic participants to be male, older, and currently smoking, have lower HDL cholesterol levels and higher BMI, non-HDL cholesterol levels, and systolic blood pressure.A substantial proportion of people in Japan with untreated diabetes have poor glycemic control. Targeting relevant factors for untreated diabetes in screening programs may be effective to enhance the treatment and control of diabetes.

    Full Text Available Abstract Background Exposure assessment has shifted from pollutant monitoring in air, soil, and water toward personal exposure measurements and biomonitoring. This trend along with the paucity of health effect data for many of the pollutants studied raise ethical and scientific challenges for reporting results to study participants. Methods We interviewed 26 individuals involved in biomonitoring studies, including academic scientists, scientists from environmental advocacy organizations, IRB officials, and study participants; observed meetings where stakeholders discussed these issues; and reviewed the relevant literature to assess emerging ethical, scientific, and policy debates about personal exposure assessment and biomonitoring, including public demand for information on the human health effects of chemical body burdens. Results We identify three frameworks for report-back in personal exposure studies: clinical ethics; community-based participatory research; and citizen science 'data judo.' The first approach emphasizes reporting results only when the health significance of exposures is known, while the latter two represent new communication strategies where study participants play a role in interpreting, disseminating, and leveraging results to promote community health. We identify five critical areas to consider in planning future biomonitoring studies. Conclusion Public deliberation about communication in personal exposure assessment research suggests that new forms of community-based research ethics and participatory scientific practice are emerging.

    ABSTRACT Background: To prepare for careers in medicine, medical trainees must develop clinical teaching skills. It is unclear if Canadian medical students need or want to develop such skills. We sought to assess Canadian students’ perceptions of clinical teaching, and their desire to pursue clinical teaching skills development via a clinical teaching elective (CTE) in their final year of medical school. Methods: We designed a descriptive cross-sectional study of Canadian senior medical students, using an online survey to gauge teaching experience, career goals, perceived areas of confidence, and interest in a CTE. Results: Students at 13 of 17 Canadian medical schools were invited to participate in the survey (4154 students). We collected 321 responses (7.8%). Most (75%) respondents expressed confidence in giving presentations, but fewer were confident providing bedside teaching (47%), teaching sensitive issues (42%), and presenting at journal clubs (42%). A total of 240 respondents (75%) expressed interest in participating in a CTE. The majority (61%) favored a two week elective, and preferred topics included bedside teaching (85%), teaching physical examination skills (71%), moderation of small group learning (63%), and mentorship in medicine (60%). Conclusion: Our study demonstrates that a large number of Canadian medical students are interested in teaching in a clinical setting, but lack confidence in skills specific to clinical teaching. Our respondents signaled interest in participating in an elective in clinical teaching, particularly if it is offered in a two-week format. PMID:28178914

    The Hα and optical broad-band images of 25 nearby Wolf-Rayet (WR) galaxies are presented. The WR galaxies are known to have a recent (≤10 Myr) and massive star formation episode. The photometric Hα fluxes are estimated and corrected for extinction and line contamination in the filter pass-bands. The star formation rates (SFRs) are estimated using Hα images and from archival data in the far-ultraviolet (FUV), far-infrared (FIR) and 1.4-GHz radio continuum wavebands. A comparison of SFRs estimated from different wavebands is made after including similar data available in the literature for other WR galaxies. The Hα-based SFRs are found to be tightly correlated with SFRs estimated from the FUV data. The correlations also exist with SFR estimates based on the radio and FIR data. The WR galaxies also follow the radio-FIR correlation known for normal star-forming galaxies, although it is seen here that the majority of dwarf WR galaxies have a radio deficiency. An analysis using the ratio of non-thermal to thermal radio continuum and the ratio of the FUV to Hα SFRs indicates that WR galaxies have lower non-thermal radio emission compared to normal galaxies, most likely due to a lack of supernovae in the very young star formation episode in the WR galaxies. The morphologies of 16 galaxies in our sample are highly suggestive of an ongoing tidal interaction or a past merger in these galaxies. This survey strengthens the conclusions obtained from previous similar studies indicating the importance of tidal interactions in triggering star-formation in WR galaxies.

    Postal survey is a simple and efficient way to collect information in large study samples. The purpose of this study was to find out differences between older adults who responded to a postal survey on health outcomes and those who did not, and to examine the importance of frailty, physical functional decline and poor self-reported health in determining non-response. We mailed out a questionnaire on general health twice at a year's interval to 1000 individuals ≥60 years, and members of the medical insurance scheme of the French national education system. At Year1, 535 persons responded to the questionnaire (65% women, 70.9 ± 8.4 years). A year later (Year2), we obtained 384 responses (63.3% women, 70.5 ± 7.8 years). Compared to respondents, non-respondents at Year2 were more frequently categorized as frail, reported more often to be in bad health, and had more physical functional declines. Frailty, physical functional decline and poor self-reported health increased the likelihood of not responding to Year2 questionnaire, with poor self-reported health weakening the association of physical functional decline and non-response. Respondents of this postal survey are fitter and healthier than non-respondents. This participation bias precludes the generalization of postal surveys results.

    Full Text Available The use of information and communication technologies both in higher education and in business environments has been dramatically increasing in the past two decades. Blended learning (either synchronous or asynchronous has been gaining ground and becoming a major alternative to standard teaching. In Greece, higher education institutions provide a substantial part of their curricula in electronic form and instructors are urged to use the e-learning tools more. However, students are not always willing to explore and take full advantage of the enhanced possibilities and often are not involved at all. Various modules of on-line education attract students in different ways, thus leading to a natural tendency to use different tools to fulfill their needs. This study aims at exploring the correlation between students’ awareness for this learning model, their level of participation in such learning formats and their final performance. Comparative results for participation and performance are presented for a variety of relevant interactive tools employed by the Learning Management System (LMS of TEI of Epirus, a higher education institution in Greece.

    The relation of income and socioeconomic status with suicide rates remains unclear. Most previous studies have focused on the relationship between suicide rates and macroeconomic factors (e.g., economic growth rate). Therefore, we aimed to identify the relationship between individuals' socioeconomic position and suicide risk. We analyzed suicide mortality rates across socioeconomic positions to identify potential trends using observational data on suicide mortality collected between January 2003 and December 2013 from 1,025,340 national health insurance enrollees. We followed the subjects for 123.5 months on average. Socioeconomic position was estimated using insurance premium levels. To examine the hazard ratios of suicide mortality in various socioeconomic positions, we used Cox proportional hazard models. We found that the hazard ratios of suicide showed an increasing trend as socioeconomic position decreased. After adjusting for gender, age, geographic location, and disability level, Medicaid recipients had the highest suicide hazard ratio (2.28; 95% CI, 1.87-2.77). Among the Medicaid recipients, men had higher hazard ratios than women (2.79; 95% CI, 2.17-3.59 vs. 1.71; 95% CI, 1.25-2.34). Hazard ratios also varied across age groups. The highest hazard ratio was found in the 40-59-year-old group (3.19; 95% CI, 2.31-4.43), whereas the lowest ratio was found in those 60 years and older (1.44; 95% CI, 1.09-1.87). Our results illuminate the relationship between socioeconomic position and suicide rates and can be used to design and implement future policies on suicide prevention. Copyright © 2017 The Authors.

    Full Text Available Abstract Background Public satisfaction with policy process influences the legitimacy and acceptance of policies, and conditions the future political process, especially when contending ethical value judgments are involved. On the other hand, public involvement is required if effective policy is to be developed and accepted. Methods Using the data from a large-scale national opinion survey, this study evaluates public appraisal of past government efforts to legalize organ transplant from brain-dead bodies in Japan, and examines the public's intent to participate in future policy. Results A relatively large percentage of people became aware of the issue when government actions were initiated, and many increasingly formed their own opinions on the policy in question. However, a significant number (43.3% remained unaware of any legislative efforts, and only 26.3% of those who were aware provided positive appraisals of the policymaking process. Furthermore, a majority of respondents (61.8% indicated unwillingness to participate in future policy discussions of bioethical issues. Multivariate analysis revealed the following factors are associated with positive appraisals of policy development: greater age; earlier opinion formation; and familiarity with donor cards. Factors associated with likelihood of future participation in policy discussion include younger age, earlier attention to the issue, and knowledge of past government efforts. Those unwilling to participate cited as their reasons that experts are more knowledgeable and that the issues are too complex. Conclusions Results of an opinion survey in Japan were presented, and a set of factors statistically associated with them were discussed. Further efforts to improve policy making process on bioethical issues are desirable.

    To describe how systematic reviewers are reporting missing data for dichotomous outcomes, handling them in the analysis and assessing the risk of associated bias. We searched MEDLINE and the Cochrane Database of Systematic Reviews for systematic reviews of randomised trials published in 2010, and reporting a meta-analysis of a dichotomous outcome. We randomly selected 98 Cochrane and 104 non-Cochrane systematic reviews. Teams of 2 reviewers selected eligible studies and abstracted data independently and in duplicate using standardised, piloted forms with accompanying instructions. We conducted regression analyses to explore factors associated with using complete case analysis and with judging the risk of bias associated with missing participant data. Of Cochrane and non-Cochrane reviews, 47% and 7% (previews) and assuming no participants with missing data had the event (4%). The use of complete case analysis was associated only with Cochrane reviews (relative to non-Cochrane: OR=7.25; 95% CI 1.58 to 33.3, p=0.01). 65% of reviews assessed risk of bias associated with missing data; this was associated with Cochrane reviews (relative to non-Cochrane: OR=6.63; 95% CI 2.50 to 17.57, p=0.0001), and the use of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology (OR=5.02; 95% CI 1.02 to 24.75, p=0.047). Though Cochrane reviews are somewhat less problematic, most Cochrane and non-Cochrane systematic reviews fail to adequately report and handle missing data, potentially resulting in misleading judgements regarding risk of bias.

  15. The effect of question order on self-rated general health status in a multilingual survey context.

    Science.gov (United States)

    Lee, Sunghee; Grant, David

    2009-06-15

    Current practices recommend placing a self-rated health question before specific health items in survey questionnaires to minimize potential order effects. Because this recommendation is based on data collected in English, its applicability to other languages is unknown. This study examines whether there is an order effect associated with self-rated health for interviews conducted in English and Spanish languages. An experiment was conducted by using the 2007 California Health Interview Survey, where questions on self-rated health were inserted in 1 of 2 locations: preceding and following question items on specific chronic conditions. Respondents were randomly assigned to 1 of 2 versions of the locations by the split-half method. Although no order effect was present in the English interviews, the authors found a significant and large effect with Spanish interviews: Self-rated health appeared much worse when asked before chronic conditions than when asked after them. This order effect was larger among females than males. Order effects for self-rated health differ by interview language; inferences about the health status of Spanish-speaking populations (and potentially Latinos) depend on question order. If maintaining comparability is important, the authors' finding contradicts current recommendations, as inserting the self-rated health question before specific questions led to larger differences in health status between English and Spanish speakers.

    Even as the number of children with health insurance has increased, coverage transitions--movement into and out of coverage and between public and private insurance--have become more common. Using data from 1996 to 2005, we examine whether insurance instability has implications for access to primary care. Because unobserved factors related to parental behavior and child health may affect both the stability of coverage and utilization, we estimate the relationship between insurance and the probability that a child has at least one physician visit per year using a model that includes child fixed effects to account for unobserved heterogeneity. Although we find that unobserved heterogeneity is an important factor influencing cross-sectional correlations, conditioning on child fixed effects we find a statistically and economically significant relationship between insurance coverage stability and access to care. Children who have part-year public or private insurance are more likely to have at least one doctor's visit than children who are uninsured for a full year, but less likely than children with full-year coverage. We find comparable effects for public and private insurance. Although cross-sectional analyses suggest that transitions directly between public and private insurance are associated with lower rates of utilization, the evidence of such an effect is much weaker when we condition on child fixed effects.

    The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) and Cluster Lensing And Supernova survey with Hubble (CLASH) multi-cycle treasury programs with the Hubble Space Telescope (HST) have provided new opportunities to probe the rate of core-collapse supernovae (CCSNe) at high redshift, now extending to $z\\approx2.5$. Here we use a sample of approximately 44 CCSNe to determine volumetric rates, $R_{CC}$, in six redshift bins in the range $0.195\\%$ confidence) with SFRs from IR luminous galaxies, or with SFR models that include simple evolution in the initial mass function over time. This scaling factor is expected if the fraction of the IMF contributing to CCSN progenitors is in the 8 to 50 $M_{\\odot}$ range. It is not supportive, however, of an upper mass limit for progenitors at $<20\\,M_{\\odot}$.

    Tidal freshwater marshes contribute to estuary health by filtering excess sediment and nutrients delivered from the watershed, but their extent and persistence is threatened by rising sea level. To maintain a semi-emergent position, the marsh surface must gain elevation by accreting mineral and/or organic material at a rate comparable to sea level rise. Historic records of sea level rise (SLR) are available from tide gages, but records of historic elevation change at the necessary precision are rare. Additionally, sedimentation, compaction, erosion, and the resultant net elevation gain are spatially heterogeneous across a marsh, varying with elevation, among other factors. We solve this issue at our study site by taking advantage of a 1992 total station survey of the marsh and RTK GPS surveys from 2005 and 2012, and registering them all against an airborne LiDAR derived DEM. Thus, although no points are directly reoccupied, survey vs. DEM trends can be found for each survey, and an average rate of elevation change can be calculated as a function of DEM elevation. We found rates of net elevation gain ranging spatially from 3-5 mm/yr between the years 1992-2012, similar to the historic rate of SLR at a nearby Washington, DC tide gage of 4 mm/yr over the past 28 years. Net elevation change varied as DEM elevation increased, with several local minima and maxima potentially related to variations and transitions in vegetation community. Assuming IPCC predicted sea level rise and a fixed relationship between elevation and net accretion, we then forecast marsh elevation relative to sea level and associated vegetative community changes through the 21st century using an inundation model that considers net accretion and a constant relationship between vegetation community type and elevation.

    Full Text Available We examined whether self-ratings of “being active” among older people living in four different settings (major city high and lower density suburbs, a regional city, and a rural area were associated with out-of-home participation and outdoor physical activity. A mixed-methods approach (survey, travel diary, and GPS tracking over a one-week period was used to gather data from 48 individuals aged over 55 years. Self-ratings of “being active” were found to be positively correlated with the number of days older people spent time away from home but unrelated to time traveled by active means (walking and biking. No significant differences in active travel were found between the four study locations, despite differences in their respective built environments. The findings suggest that additional strategies to the creation of “age-friendly” environments are needed if older people are to increase their levels of outdoor physical activity. “Active aging” promotion campaigns may need to explicitly identify the benefits of walking outdoors to ambulatory older people as a means of maintaining their overall health, functional ability, and participation within society in the long-term and also encourage the development of community-based programs in order to facilitate regular walking for this group.

    Full Text Available Introduction In order to discharge the patients receiving treatment with large radiation doses of 131I for thyroid cancer, it is necessary to measure and evaluate the external dose rates of these patients. The aim of the study was to assess a new method of external dose rate measurement, and to analyze the obtained results as a function of time. Materials and Methods In this study, a telescopic radiation survey meter was utilized to measure the external dose rates of a sample population of 192 patients receiving treatment with high-dose 131I at one, 24, and 48 hours after dose administration. Results The proposed technique could reduce the occupational radiation exposure of the physicist by a factor of 1/16. Moreover, the external dose rates of both genders rapidly decreased with time according to bi-exponential equations, which could be attributed to the additional factors associated with iodine excretion, as well as the physiology of the body in terms of 131I uptake. Conclusion According to the results of this study, telescopic radiation survey meter could be used to measure the external dose rates of patients receiving treatment with 131I. Furthermore, the average difference in the radiation exposure between female and male patients was calculated to be less than 17%.

    The aim of the current study was to examine the association of personality, neighbourhood, and civic participation with the level of perceived social support if needed. The sample consists of a total of 35,797 men (16,035) and women (19,762) drawn from the Nord-Trøndelag Health Study 3 (HUNT3), aged 20-89, with a fully completed short version of the Eysenck Personality Questionnaire (EPQ) including a complete response to questions regarding perceived social support. A multinomial logistic regression model was used to investigate the association between the three-category outcomes (high, medium, and low) of perceived social support. The Chi-square test detected a significant (p personality, sense of community, civic participation, self-rated health, living arrangement, age groups, gender, and perceived social support, except between perceived social support and loss of social network, in which no significance was found. The crude and adjusted multinomial logistic regression models show a relation between medium and low scores on perceived social support, personality, and sources of social support. Interactions were observed between gender and self-rated health. There is an association between the level of perceived social support and personality, sense of community in the neighbourhood, and civic participation. Even if the interaction between men and self-reported health decreases the odds for low and medium social support, health professionals should be aware of men with poor health and their lack of social support.

    We present the supernova (SN) sample and Type-Ia SN (SN Ia) rates from the Cluster Lensing And Supernova survey with Hubble (CLASH). Using the Advanced Camera for Surveys and the Wide Field Camera 3 on the Hubble Space Telescope (HST), we have imaged 25 galaxy-cluster fields and parallel fields of non-cluster galaxies. We report a sample of 27 SNe discovered in the parallel fields. Of these SNe, approximately 13 are classified as SN Ia candidates, including four SN Ia candidates at redshifts z greater than 1.2.We measure volumetric SN Ia rates to redshift 1.8 and add the first upper limit on the SN Ia rate in the range z greater than 1.8 and less than 2.4. The results are consistent with the rates measured by the HST/ GOODS and Subaru Deep Field SN surveys.We model these results together with previous measurements at z less than 1 from the literature. The best-fitting SN Ia delay-time distribution (DTD; the distribution of times that elapse between a short burst of star formation and subsequent SN Ia explosions) is a power law with an index of 1.00 (+0.06(0.09))/(-0.06(0.10)) (statistical) (+0.12/-0.08) (systematic), where the statistical uncertainty is a result of the 68% and 95% (in parentheses) statistical uncertainties reported for the various SN Ia rates (from this work and from the literature), and the systematic uncertainty reflects the range of possible cosmic star-formation histories. We also test DTD models produced by an assortment of published binary population synthesis (BPS) simulations. The shapes of all BPS double-degenerate DTDs are consistent with the volumetric SN Ia measurements, when the DTD models are scaled up by factors of 3-9. In contrast, all BPS single-degenerate DTDs are ruled out by the measurements at greater than 99% significance level.

    Effective policies have potential to improve diet and reduce obesity. School food policies reach most children in the United States. To assess the nutritional quality of foods chosen by students and meal participation rates before and after the implementation of new school meal standards authorized through the Healthy Hunger-Free Kids Act. This descriptive, longitudinal study examined changes in the nutritional quality of 1,741,630 school meals at 3 middle schools and 3 high schools in an urban school district in Washington state. Seventy two hundred students are enrolled in the district; 54% are eligible for free and reduced-price meals. Student food selection data were collected daily from January 2011 through January 2014 during the 16 months prior to and the 15 months after implementation of the Healthy Hunger-Free Kids Act. The Healthy Hunger-Free Kids Act. Nutritional quality was assessed by calculating monthly mean adequacy ratio and energy density of the foods selected by students each day. Six nutrients were included in the mean adequacy ratio calculations: calcium, vitamin C, vitamin A, iron, fiber, and protein. Monthly school meal participation was calculated as the mean number of daily meals served divided by student enrollment. Mean monthly values of mean adequacy ratio, energy density, and participation were compared before and after policy implementation. After implementation of the Healthy Hunger-Free Kids Act, change was associated with significant improvement in the nutritional quality of foods chosen by students, as measured by increased mean adequacy ratio from a mean of 58.7 (range, 49.6-63.1) prior to policy implementation to 75.6 (range, 68.7-81.8) after policy implementation and decreased energy density from a mean of 1.65 (range, 1.53-1.82) to 1.44 (range, 1.29-1.61), respectively. There was negligible difference in student meal participation following implementation of the new meal standards with 47% meal participation (range, 40

    Modern large-scale surveys have allowed the identification of large numbers of white dwarfs. However, these surveys are subject to complicated target selection algorithms, which make it almost impossible to quantify to what extent the observational biases affect the observed populations. The LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope) Spectroscopic Survey of the Galactic anti-center (LSS-GAC) follows a well-defined set of criteria for selecting targets for observations. This advantage over previous surveys has been fully exploited here to identify a small yet well-characterised magnitude-limited sample of hydrogen-rich (DA) white dwarfs. We derive preliminary LSS-GAC DA white dwarf luminosity and mass functions. The space density and average formation rate of DA white dwarfs we derive are 0.83+/-0.16 x 10^{-3} pc^{-3} and 5.42 +/- 0.08 x 10^{-13} pc^{-3} yr^{-1}, respectively. Additionally, using an existing Monte Carlo population synthesis code we simulate the population of single DA w...

    Concentration and source rate of precursor vapors participating in particle formation and subsequent growth were investigated during the Pearl River Delta intensive campaign (PRD2004, October 2004) in southeastern China. Four new particle formation event days and a typical non-event day were selected for our analysis. Atmospheric sulphuric acid, the important precursor vapor in nucleation and growth, were simulated with a pseudo steady-state model based on the measurements of SO2, NOX, O3, CO, non-methane hydrocarbon (NMHC) and ambient particle number concentrations as well as modeled photolysis frequencies obtained from measurements. The maximum midday sulphuric acid concentrations vary from 4.53 × 107 to 2.17 × 108 molecules cm-3, the corresponding source rate via reaction of OH and SO2 range between 2.37 × 106 and 1.16 × 107 molecules cm-3 s-1. Nucleation mode growth rate was derived from size spectral evolution during the events to be 6.8-13.8 nm h-1. Based on the growth rate, concentration of the vapors participating in subsequent growth were estimated to vary from 1.32 × 10s to 2.80 × 108 molecules cm-3 with corresponding source rate between 7.26 × 106 and 1.64 × 107 molecules cm-3 s-1. Our results show the degree of pollution is larger in PRD. Sulphuric acid concentrations are fairly high and have a close correlation with new particle formation events. Budget analysis shows that sulphuric acid alone is not enough for required growth; other nonvolatile vapors are needed. However, sulphuric acid plays an important role in growth; the contribution of sulphuric acid to growth in PRD is 12.4%-65.2%.

    Academic promotion has been difficult for women and faculty of minority race. We investigated whether completion of a faculty development fellowship would equalize promotion rates of female and minority graduates to those of male and white graduates. All graduates of the Michigan State University Primary Care Faculty Development Fellowship Program from 1989-1998 were sent a survey in 1999, which included questions about academic status and appointment. We compared application and follow-up survey data by gender and race/ethnicity. Telephone calls were made to nonrespondents. A total of 175 (88%) graduating fellows responded to the follow-up survey. Information on academic rank at entry and follow-up was obtained from 28 of 48 fellows with missing information on promotion. Male and female graduates achieved similar academic promotion at follow-up, but there was a trend toward lower promotion rates for minority faculty graduates compared to white graduates. In the multivariate analysis, however, only age, years in rank, initial rank, and type of appointment (academic versus clinical) were significant factors for promotion. Academic advancement is multifactorial and appears most related to time in rank, stage of life, and career choice. Faculty development programs may be most useful in providing skill development and career counseling.

    We examined the applicability of radioelement data from the National Aerial Radiometric Reconnaissance, an element of the National Uranium Resource Evaluation, to estimate terrestrial gamma-ray absorbed dose rates, by comparing dose rates calculated from aeroradiometric surveys of uranium, thorium, and potassium concentrations with dose rates calculated from a radiogeologic data base and the distribution of lithologies in California. Gamma-ray dose rates increase generally from north to south following lithological trends, with low values of 25-30 nGy h-1 in the northernmost 1 x 2 degrees quadrangles between 41 and 42 degrees N to high values of 75-100 nGy h-1 in southeastern California. Lithologic-based estimates of mean dose rates in the quadrangles generally match those from aeroradiometric data, with statewide means of 63 and 60 nGy h-1, respectively. These are intermediate between a population-weighted global average of 51 nGy h-1 reported in 1982 by UNSCEAR and a weighted continental average of 70 nGy h-1, based on the global distribution of rock types. The concurrence of lithologically and aeroradiometrically determined dose rates in California, with its varied geology and topography encompassing settings representative of the continents, indicates that the National Aerial Radiometric Reconnaissance data are applicable to estimates of terrestrial absorbed dose rates from natural gamma emitters.

    2013-01-01

    We use the HiZELS narrow-band H-alpha survey in combination with CANDELS, UKIDSS and WIRDS near-infrared imaging, to investigate the morphologies, merger rates and sizes of a sample of H-alpha emitting galaxies in the redshift range z=0.40 - 2.23, an epoch encompassing the rise to the peak of the star formation rate density. Merger rates are estimated from space- and ground-based imaging using the M20 coefficient. To account for the increase in the specific star-formation rate (sSFR) of the star forming `main-sequence' with redshift, we normalise the star-formation rate of galaxies at each epoch to the typical value derived from the H-alpha luminosity function. Once this trend in sSFR is removed we see no evidence for an increase in the number density of star-forming galaxies or the merger rate with redshift. We thus conclude that neither is the main driver of the enhanced star-formation rate density at z=1-2, with secular processes such as instabilities within efficiently fuelled, gas-rich discs or multiple ...

    Full Text Available Introduction Family history of diabetes has been recognized as an important risk factor of the disease. Family medical history represents valuable genomic information because it characterizes the combined interactions between environmental, behavioral, and genetic factors. This study examined the strength and effect of having a family history of diabetes on the prevalence of self-reported, previously diagnosed diabetes among adult participants of the National Health and Nutrition Examination Survey 1999–2002. Methods The study population included data from 10,283 participants aged 20 years and older. Gender, age, race/ethnicity, poverty income ratio, education level, body mass index, and family history of diabetes were examined in relation to diabetes status. Diabetes prevalence estimates and odds ratios of diabetes were calculated based on family history and other factors. Results The prevalence of diabetes among individuals who have a first-degree relative with diabetes (14.3% was significantly higher than that of individuals without a family history (3.2%, corresponding to a crude odds ratio of five. Both prevalence and odds ratio estimates significantly increased with the number of relatives affected with diabetes. Family history was also associated with several demographic and risk factors. Conclusion Family history of diabetes was shown to be a significant predictor of diabetes prevalence in the adult U.S. population. We advocate the inclusion of family history assessment in public health prevention and screening programs as an inexpensive and valuable source of genomic information and measure of diabetes risk.

    This study reports the first attempt to record the radioactive background due to gamma radiation in Lesvos Island (Greece). The study reports the results from 335 outdoor total gamma effective dose rate measurements conducted using GPS navigation and a Geiger-Muller detector (Bicron, Micro Sievert) on the whole surface of the island together with a digital map produced by appropriate mapping GIS programme. The study also reports the measurements of outdoor gamma dose rates due to the 238U, 232Th and 40K radionuclides as estimated via in situ gamma-ray spectrometry measurements performed at 26 sites using a 3 x 3 inch NaI (thallium activated) portable detector. The results from the outdoor total gamma effective dose rates range between 0.0023 and 0.28 microSv h(-1). The highest outdoor total gamma effective dose rates (0.013-0.28 microSv h(-1)) were detected in the northeastern part of the island and the intermediate rates (0.066-0.13 microSv h(-1)) in the central region. The outdoor gamma dose rates due to 238U, 232Th and 40K radionuclides range between 1.7 +/- 0.8 and 154 +/- 7 nGy h(-1) with an average of 86 +/- 6 nGy h(-1). The average contribution of each of the examined radionuclides (238U, 232Th and 40K) to the total gamma dose rate was found to be equal to 12 +/- 4% for 238U, 58 +/- 6% for 232Th and 29 +/- 7% for 40K, respectively.

    Full Text Available Background and Purpose: Patients who experience a stroke or transient ischemic attack (TIA are known to be at high risk of subsequent vascular events, underscoring the need for secondary preventive intervention. However, previous studies have indicated insufficiency in the implementation of secondary prevention, emphasizing the need to develop effective methods of follow-up. In the present study, we examined the potential of implementing a telephone-based, nurse-led, secondary preventive follow-up in stroke and TIA patients on a population level by analyzing the participation rate, reasons for nonparticipation, and one-year mortality. Methods: Between January 1, 2010 and December 31, 2011, all patients admitted to Östersund hospital, Sweden, and diagnosed with either stroke or TIA were considered for inclusion into the secondary preventive follow-up. Baseline data were collected at the hospital, and reasons for nonparticipation were documented. Multivariate logistic regression was performed to identify predictors of the patient decision not to participate and to explore independent associations between baseline characteristics and exclusion. A one-year follow-up of mortality was also performed; the survival functions of the three groups (included, excluded, declining participation was calculated using the Kaplan-Meier estimator. Results: From a total of 810 identified patients, 430 (53.1% were included in the secondary preventive follow-up, 289 (35.7% were excluded mainly due to physical or cognitive disability, and 91 (11.2% declined participation. Age ≥85 years, ischemic and hemorrhagic stroke, modified Rankin scale score >3, body mass index ≥25, congestive heart failure, and lower education level were independently associated with exclusion, whereas lower education level was the only factor independently associated with the patient decision not to participate. Exclusion was associated with a more than 12 times higher risk of mortality

    AIM: To examine the regional variations in mortality rates of pancreatic cancer in China.METHODS: Aggregated mortality data of pancreatic cancer were extracted from the 1990-1992 national death of all causes and its mortality survey in China. Age specific and standardized mortality rates were calculated at both national and provincial levels with selected characteristics including sex and residence status.RESULTS: Mortality of pancreatic cancer ranked the ninth and accounted for 1.38 percent of the total malignancy deaths. The crude and age standardized mortality rates of pancreatic cancer in China in the period of 1990-1992 were 1.48/100 000 and 1.30/100 000, respectively. Substantial regional variations in mortality rates across China were observed with adjusted mortality rates ranging from 0.43/100 000 to 3.70/100 000 with an extremal value of 8.7.Urban residents had significant higher pancreatic mortality than rural residents.CONCLUSION: The findings of this study show different mortality rates of this disease and highlight the importance of further investigation on factors, which might contribute to the observed epidemiological patterns.

    Full Text Available The design of distributed explicit rate flow control schemes for the multi input multi output services has received the considerable focus with the ever increasing wireless and the wired data applications. This paper proposes two novel multi points to multi point flow control schemes. The schemes are based on the distributed self-tuning proportional integrative plus derivative controller. The control parameters can be designed to ensure the stability of the control loop in terms of the source rate. In order to regulate the transmission rate the controllers are located at the wireless/wired multi point to multipoint multicast source. We further analyze the theoretical aspects of the proposed algorithm, show how the control mechanism can be used to design a controller to support many-to-many multi-rate multicast transmission based on ER feedback, and verify its agreement with simulations in the case of bottleneck link appearing in a multicast tree. The simulation results can be obtained in terms of the system stability, high link utilizations, fast response, scalability, high throughput and fairness.

    Full Text Available BACKGROUND: There is mounting evidence that discriminatory experiences can harm health. However, previous research has mainly focused on the health effects of racial discrimination in U.S. or European countries although there is pervasive discrimination by gender, age, education and other factors in Asian countries. METHODS: We analyzed the data from the 7th wave of Korean Labor and Income Panel Study to investigate the association between perceived discriminatory experience and poor self-rated health in South Korea. Perceived discriminatory experiences were measured in eight situations through a modified Experience of Discrimination questionnaire. In each of eight situations, the lifetime prevalence of perceived discriminatory experience was compared between men and women and the main causes of those experiences were identified separately by gender. After adjusting for potential confounders, we examined the association between perceived discriminatory experience and poor self-rated health in each of eight social situations and also checked the association using the number of situations of perceived discriminatory experiences. RESULTS: For both men and women, education level and age were the main sources of work-related perceived discriminatory experiences. Gender was one of the main causes among women across eight situations and more than 90% of women reported their gender as a main cause of discriminatory experience in getting higher education and at home. Discriminatory experiences in four situations were positively associated with poor self-rated health. The odds ratio for poor self-rated health for those exposed to one, two, three or four or more social situations of perceived discrimination were respectively 1.06 (95% CI : 0.87-1.29, 1.15 (95% CI : 0.96-1.55, 1.59 (95% CI : 1.19-2.14, and 1.78 (95% CI :1.26-2.51. CONCLUSION: There is consistent association between perceived discriminatory experience and poor self-rated health across eight

    Hypertension is a significant risk factor for cardiovascular disease, and epidemiological evidence suggests that it is increasing in parallel with obesity in children and adolescents in low- and middle-income countries. To identify and determine the relationship between overweight, obesity and hypertension in a community sample of school children. Anthropometric data were collected from 12,730 school children aged 12-18 years in China, India and Mexico as part of the Community Interventions for Health programme, an international study evaluating community interventions to reduce non-communicable disease by addressing the three main risk factors of tobacco use, unhealthy diets and physical inactivity. Logistic regression was used to examine the association of body mass index and gender and hypertension. Prevalence rates of hypertension were 5.2% in China, 10.1% in India and 14.1% in Mexico, and pre-hypertension rates in China, India and Mexico were 13.4%, 9.4% and 11.2%, respectively. Overweight and obesity prevalence rates varied by country and were 16.6% in China, 4.1% in India and 37.1% in Mexico. In all countries there was a significant association between overweight and obesity and rates of hypertension. Overweight children were 1.7-2.3 times more likely to be hypertensive and obese children 3.5-5.5 more likely to show hypertension than those of normal weight. Rates of hypertension and overweight and obesity are high in school children in China, India and Mexico, and increased bodyweight is a significant risk factor for hypertension.

    We present precise measurements of the growth rate of cosmic structure for the redshift range 0.1 < z < 0.9, using redshift-space distortions in the galaxy power spectrum of the WiggleZ Dark Energy Survey. Our results, which have a precision of around 10% in four independent redshift bins, are well-fit by a flat LCDM cosmological model with matter density parameter Omega_m = 0.27. Our analysis hence indicates that this model provides a self-consistent description of the growth of cosmic struc...

    Star-forming galaxies at $z > 1$ exhibit significantly different properties to local galaxies of equivalent stellar mass. Not only are high-redshift star-forming galaxies characterized by higher star formation rates and gas fractions than their local counterparts, they also appear to host star-forming regions with significantly different physical conditions, including greater electron densities. To understand what physical mechanisms are responsible for the observed evolution of star-forming conditions we have assembled the largest sample of star-forming galaxies at $z\\sim 1.5$ with emission-line measurements of the $\\mathrm{[OII]} \\lambda \\lambda 3726,3729$ doublet. By comparing our $z\\sim 1.5$ sample to local galaxy samples with equivalent distributions of stellar mass, star formation rate and specific star formation rate we investigate the proposed evolution in electron density and its dependence on global properties. We measure an average electron density of $114_{-27}^{+28} \\, \\mathrm {cm}^{-3} $ for our...

    2012-06-01

    With the goal of investigating the degree at which the MIR luminosity in the Wide-field Infrared Survey Explorer (WISE) traces the SFR, we analyse 3.4, 4.6, 12 and 22 m data in a sample of ∼ 140,000 star-forming galaxies or star-forming regions covering a wide range in metallicity 7.66 < 12 + \\log (O/H) < 9.46, with redshift < 0.4. These star-forming galaxies or star-forming regions are selected by matching the WISE Preliminary Release Catalog with the star-forming galaxy Catalog in SDSS DR8 provided by JHU/MPA. We study the relationship between the luminosity at 3.4, 4.6, 12 and 22 m from WISE and H luminosity in SDSS DR8. From these comparisons, we derive reference SFR indicators for use in our analysis. Linear correlations between SFR and the 3.4, 4.6, 12 and 22 m luminosity are found, and calibrations of SFRs based on L(3.4), L(4.6), L(12) and L(22) are proposed. The calibrations hold for galaxies with verified spectral observations. The dispersion in the relation between 3.4, 4.6, 12 and 22 m luminosity and SFR relates to the galaxy’s properties, such as 4000 Å break and galaxy color.

    Vitiligo is a chronic depigmenting skin disorder which affects around 0.5-1% of the world's population. The outcome measures used most commonly in trials to judge treatment success focus on repigmentation. Patient-reported outcome measures of treatment success are rarely used, although recommendations have been made for their inclusion in vitiligo trials. This study aimed to evaluate the face validity of a new patient-reported outcome measure of treatment response, for use in future trials and clinical practice. An online survey to gather initial views on what constitutes treatment success for people with vitiligo or their parents/carers, followed by online discussion groups with patients to reach consensus on what constitutes treatment success for individuals with vitiligo, and how this can be assessed in the context of trials. Participants were recruited from an existing database of vitiligo patients and through posts on the social network sites Facebook and Twitter. A total of 202 survey responses were received, of which 37 were excluded and 165 analysed. Three main themes emerged as important in assessing treatment response: a) the match between vitiligo and normal skin (how well it blends in); b) how noticeable the vitiligo is and c) a reduction in the size of the white patches. The majority of respondents said they would consider 80% or more repigmentation to be a worthwhile treatment response after 9 months of treatment. Three online discussion groups involving 12 participants led to consensus that treatment success is best measured by asking patients how noticeable their vitiligo is after treatment. This was judged to be best answered using a 5-point Likert scale, on which a score of 4 or 5 represents treatment success. This study represents the first step in developing a patient reported measure of treatment success in vitiligo trials. Further work is now needed to assess its construct validity and responsiveness to change.

    Full Text Available Abstract Background It is important that response rates to postal surveys are as high as possible to ensure that the results are representative and to maximise statistical power. Previous research has suggested that any personalisation of approach helps to improve the response rate. This experiment tested whether personalising questionnaires by hand signing the covering letter improved the response rate compared with a non-personalised group where the investigator's signature on the covering letter was scanned into the document and printed. Methods Randomised controlled trial. Questionnaires about surgical techniques of caesarean section were mailed to 3,799 Members and Fellows of the Royal College of Obstetricians and Gynaecologists resident in the UK. Individuals were randomly allocated to receive a covering letter with either a computer printed signature or a hand written signature. Two reminders were sent to non-respondents. The outcome measures were the proportion of questionnaires returned and their time to return. Results The response rate was 79.1% (1506/1905 in the hand-signed group and 78.4% (1484/1894 in the scanned and printed signature group. There was no detectable difference between the groups in response rate or time taken to respond. Conclusion No advantage was detected to hand signing the covering letter accompanying a postal questionnaire to health professionals.

    The radius and surface composition of an exploding massive star, as well as the explosion energy per unit mass, can be measured using early UV observations of core-collapse supernovae (SNe). We present the first results from a simultaneous GALEX/PTF search for early ultraviolet (UV) emission from SNe. Six SNe II and one Type II superluminous SN (SLSN-II) are clearly detected in the GALEX near-UV (NUV) data. We compare our detection rate with theoretical estimates based on early, shock-cooling UV light curves calculated from models that fit existing Swift and GALEX observations well, combined with volumetric SN rates. We find that our observations are in good agreement with calculated rates assuming that red supergiants (RSGs) explode with fiducial radii of 500 R{sub ⊙}, explosion energies of 10{sup 51} erg, and ejecta masses of 10 M{sub ⊙}. Exploding blue supergiants and Wolf–Rayet stars are poorly constrained. We describe how such observations can be used to derive the progenitor radius, surface composition, and explosion energy per unit mass of such SN events, and we demonstrate why UV observations are critical for such measurements. We use the fiducial RSG parameters to estimate the detection rate of SNe during the shock-cooling phase (<1 day after explosion) for several ground-based surveys (PTF, ZTF, and LSST). We show that the proposed wide-field UV explorer ULTRASAT mission is expected to find >85 SNe per year (∼0.5 SN per deg{sup 2}), independent of host galaxy extinction, down to an NUV detection limit of 21.5 mag AB. Our pilot GALEX/PTF project thus convincingly demonstrates that a dedicated, systematic SN survey at the NUV band is a compelling method to study how massive stars end their life.

    The rate of mass accumulation due to galaxy merging depends on the mass, density, and velocity distribution of galaxies in the near neighborhood of a host galaxy. The fractional luminosity in kinematic pairs combines all of these effects in a single estimator which is relatively insensitive to population evolution. Here we use a k-corrected and evolution compensated volume-limited sample drawing about 300 redshifts from CFGRS and 3000 from CNOC2 to measure the rate and redshift evolution of merging. We identify kinematic pairs with projected separations less than either 50 or 100 \\hkpc and rest-frame velocity differences of less than 1000\\kms. The fractional luminosity in pairs is modeled as f_L(Delta v,r_p,M_r^{ke})(1+z)^{m_L} where [f_L,m_L] are [0.14+/-0.07,0+/-1.4] and [0.37+/-0.7,0.1+/-0.5] for r_p= 0.2 M*) is 0.02+/-0.01(1+z)^{0.1+/-0.5} M*~Gyr^{-1}. Present day high-luminosity galaxies therefore have accreted approximately 0.15M* of their mass over the approximately 7 Gyr to redshift one. (abridged)

    Several epidemiological studies have reported that an elevated heart rate (HR) is associated with coronary atherosclerosis independently of other risk factors. Nevertheless, it is still unclear whether HR is itself the cause or there is merely an association between HR and mortality in this population. A total of 1686 patients with hypertension and chronic ischemic heart disease were included in this study. According to the resting HR, the patients were distributed in 3 groups (group 1: HR82 bpm). 580 patients (34.4%) belonged to group 1; 936 (55.5%) to group 2 and 170 (10.1%) to group 3. Patients with high HR exhibited a poorer prognosis not only due to a worse clinical profile (more concomitant cardiovascular risk factors and organ damage), but suggestively because despite the use of a similar number of drugs, patients with higher HR were associated with lesser risk control rates in daily clinical practice. Despite current guidelines that do not still recognize HR as a cardiovascular risk factor, it appears that physicians should pay more attention to it in clinical practice since high HR is warning about an increased risk.

    To investigate the prevalence of hypertension and its primary risk factors in patients with dilated cardiomyopathy (DCM). Methods Three hundred and sixty-two patients with DCM (DCM group)and 401 age-matched residents (control group) were enrolled randomly in the study, the hypertensive prevalence rate were calculated respectively in the two groups and were compared with each other; the patients in the DCM group were divided into two subgroups (hypertension subgroup and non-hypertension subgroup) according to whether the patients have hypertension;the clinical data related to blood pressure was compared between the two subgroups. Results The prevalence of hypertension in DCM group was significantly higher than that in the control group ( 32. 8% vs. 20. 1%, P< 0.01 ) ; There were no significant differences on the age, gender, occupation and left ventricular ejection fraction (LVEF) between the two subgroups, but the mean heart rate and the percentage of patients who had family history of hypertension were significantly higher in the hypertension subgroup than that in the non-hypertension subgroup ( P<0.05 and P<0. 01 ).Conclusions The prevalence of hypertension in patients with DCM was high; The increased activity of sympathetic nervous system and the hypertensive genetic factor may be the main risk factors of hypertension in patients with DCM.

    The Global Cardiometabolic Risk Profile in Patients with hypertension disease (GOOD) survey investigated the global cardiometabolic risk profile in 3464 adult outpatients with hypertension across 289 sites in 12 European countries. The pulse pressure and heart rate profile of the survey population was evaluated according to the presence or absence of metabolic syndrome and/or type 2 diabetes mellitus. History and treatment of hypertension were not counted as criteria for metabolic syndrome as they applied to all patients. Out of the 3370 recruited patients, 1033 had metabolic syndrome and 1177 had neither metabolic syndrome nor diabetes. When compared with patients with no metabolic syndrome or diabetes, patients with metabolic syndrome had higher pulse pressure (59±14 vs. 55±14 mm Hg) and heart rate (75.2±11.0 vs. 72.5±10.0 beats per min) (Ppulse pressure, which may at least in part reflect increased arterial stiffness and increased sympathetic tone. This may contribute, to some extent, to explaining the increased cardiovascular risk attributed to the presence of metabolic syndrome.

    The ALFALFA Hα survey utilizes a large sample of H i-selected galaxies from the ALFALFA survey to study star formation (SF) in the local universe. ALFALFA Hα contains 1555 galaxies with distances between ˜20 and ˜100 Mpc. We have obtained continuum-subtracted narrowband Hα images and broadband R images for each galaxy, creating one of the largest homogeneous sets of Hα images ever assembled. Our procedures were designed to minimize the uncertainties related to the calculation of the local SF rate density (SFRD). The galaxy sample we constructed is as close to volume-limited as possible, is a robust statistical sample, and spans a wide range of galaxy environments. In this paper, we discuss the properties of our Fall sample of 565 galaxies, our procedure for deriving individual galaxy SF rates, and our method for calculating the local SFRD. We present a preliminary value of log(SFRD[M ⊙ yr-1 Mpc-3]) = -1.747 ± 0.018 (random) ±0.05 (systematic) based on the 565 galaxies in our Fall sub-sample. Compared to the weighted average of SFRD values around z ≈ 2, our local value indicates a drop in the global SFRD of a factor of 10.2 over that lookback time.

    The National Cancer Institute (NCI) developed the Health Information National Trends Survey (HINTS) to monitor population trends in cancer communication practices, information preferences, health risk behaviors, attitudes, and cancer knowledge. The U.S. Food and Drug Administration (FDA) recognized HINTS as a unique data resource for informing its health communication endeavors and partnered with NCI to field HINTS-FDA 2015. HINTS-FDA 2015 was a self-administered paper instrument sent by mail May 29 to September 8, 2015, using a random probability-based sample of U.S. postal addresses stratified by county-level smoking rates, with an oversampling of high and medium-high smoking strata to increase the yield of current smokers responding to the survey. The response rate for HINTS-FDA 2015 was 33% (N = 3,738). The yield of current smokers (n = 495) was lower than expected, but the sampling strategy achieved the goal of obtaining more former smokers (n = 1,132). Public-use HINTS-FDA 2015 data and supporting documentation have been available for download and secondary data analyses since June 2016 at http://hints.cancer.gov . NCI and FDA encourage the use of HINTS-FDA for health communication research and practice related to tobacco-related communications, public knowledge, and behaviors as well as beliefs and actions related to medical products and dietary supplements.

    The purpose of this study was to determine the influence of contraception, abortion, and natural family planning (NFP) on divorce rates of US women of reproductive age. The variables of importance of religion and frequency of church attendance were also included in the analysis. The study involved 5,530 reproductive age women in the (2006-2010) National Survey of Family Growth who indicate that they were ever married. Among the women who ever used NFP only 9.6 percent were currently divorced compared with the 14.4 percent who were currently divorced among the women who never used NFP (x (2) = 5.34, P divorce - up to two times. Frequency of church attendance decreased the risk of divorce. Although there is less divorce among NFP users the reason might be due to their religiosity. Lay summary: Providers of natural family planning (NFP) frequently mention that couples who practice NFP have fewer divorces compared to couples who use contraception. Evidence for this comment is weak. This study utilized a large data set of 5,530 reproductive age women to determine the influence that contraception, sterilization, abortion, and NFP has on divorce rates. Among the women participants who ever used NFP only 9.6 percent were currently divorced compared with the 14.4 percent who used methods of contraception, sterilization or abortion as a family planning method. Frequency of church attendance also reduced the likelihood of divorce.

    Influenza vaccination is an effective strategy to reduce morbidity and mortality, particularly for those who have decreased lung functions. This study was to identify the factors that affect vaccination coverage according to the results of pulmonary function tests depending on the age. In this cross-sectional study, data were obtained from 3,224 adults over the age of 40 who participated in the fifth National Health and Nutrition Examination Survey and underwent pulmonary function testing in 2012. To identify the factors that affect vaccination rate, logistic regression analysis was conducted after dividing the subjects into two groups based on the age of 65. Influenza vaccination coverage of the entire subjects was 45.2%, and 76.8% for those aged 65 and over. The group with abnormal pulmonary function had a higher vaccination rate than the normal group, but any pulmonary dysfunction or history of COPD did not affect the vaccination coverage in the multivariate analysis. The subjects who were 40-64 years-old had higher vaccination coverage when they were less educated or with restricted activity level, received health screenings, and had chronic diseases. Those aged 65 and over had significantly higher vaccination coverage only when they received regular health screenings. Any pulmonary dysfunction or having COPD showed no significant correlation with the vaccination coverage in the Korean adult population.

    To conduct (1) a systematic survey of the reporting quality of simulation studies dealing with how to handle missing participant data (MPD) in randomized control trials and (2) summarize the findings of these studies. We included simulation studies comparing statistical methods dealing with continuous MPD in randomized controlled trials addressing bias, precision, coverage, accuracy, power, type-I error, and overall ranking. For the reporting of simulation studies, we adapted previously developed criteria for reporting quality and applied them to eligible studies. Of 16,446 identified citations, the 60 eligible generally had important limitations in reporting, particularly in reporting simulation procedures. Of the 60 studies, 47 addressed ignorable and 32 addressed nonignorable data. For ignorable missing data, mixed model was most frequently the best on overall ranking (9 times best, 34.6% of times tested) and bias (10, 55.6%). Multiple imputation was also performed well. For nonignorable data, mixed model was most frequently the best on overall ranking (7, 46.7%) and bias (8, 57.1%). Mixed model performance varied on other criteria. Last observation carried forward (LOCF) was very seldom the best performing, and for nonignorable MPD frequently the worst. Simulation studies addressing methods to deal with MPD suffered from serious limitations. The mixed model approach was superior to other methods in terms of overall performance and bias. LOCF performed worst. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Purpose. To examine relationships between leisure time physical activity (LTPA and health services utilization (H in a nationally representative sample of community-dwelling older adults. Methods. Cross-sectional data from 56,652 Canadian Community Health Survey respondents aged ≥ 50 years (48% M; 52% F; mean age 63.5 ± 10.2 years were stratified into three age groups and analysed using multivariate generalized linear modeling techniques. Participants were classified according to PA level based on self-reported daily energy expenditure. Nonleisure PA (NLPA was categorized into four levels ranging from mostly sitting to mostly lifting objects. Results. Active 50–65-year-old individuals were 27% less likely to report any GP consultations ORadj=0.73; P<0.001 and had 8% fewer GP consultations annually (IRRadj=0.92; P<0.01 than their inactive peers. Active persons aged 65–79 years were 18% less likely than inactive respondents to have been hospitalized overnight in the previous year (ORadj=0.82, P<0.05. Higher levels of NLPA were significantly associated with lower levels of HSU, across all age groups. Conclusion. Nonleisure PA appeared to be a stronger predictor of all types of HSU, particularly in the two oldest age groups. Considering strategies that focus on reducing time spent in sedentary activities may have a positive impact on reducing the demand for health services.

    Full Text Available Monitoring of foetal heart rate and its variability (FHRV covers an important role in assessing health of foetus. Many analysis methods have been used to get quantitative measures of FHRV. FHRV has been studied in time and in frequency domain and interesting clinical results have been obtained. Nevertheless, a standardized definition of FHRV and a precise methodology to be used for its evaluation are lacking. We carried out a literature overview about both frequency domain analysis (FDA and time domain analysis (TDA. Then, by using simulated FHR signals, we defined the methodology for FDA. Further, employing more than 400 real FHR signals, we analysed some of the most common indexes, Short Term Variability for TDA and power content of the spectrum bands and sympathovagal balance for FDA, and evaluated their ranges of values, which in many cases are a novelty. Finally, we verified the relationship between these indexes and two important parameters: week of gestation, indicator of foetal growth, and foetal state, classified as active or at rest. Our results indicate that, according to literature, it is necessary to standardize the procedure for FHRV evaluation and to consider week of gestation and foetal state before FHR analysis.

    We present a Spitzer InfraRed Spectrometer search for 10-36 micron molecular emission from a large sample of protoplanetary disks, including lines from H2O, OH, C2H2, HCN and CO2. This paper describes the sample and data processing and derives the detection rate of mid-infrared molecular emission as a function of stellar mass. The sample covers a range of spectral type from early M to A, and is supplemented by archival spectra of disks around A and B stars. It is drawn from a variety of nearby star forming regions, including Ophiuchus, Lupus and Chamaeleon. In total, we identify 22 T Tauri stars with strong mid-infrared H2O emission. Integrated water line luminosities, where water vapor is detected, range from 5x10^-4 to 9x10^-3 Lsun, likely making water the dominant line coolant of inner disk surfaces in classical T Tauri stars. None of the 5 transitional disks in the sample show detectable gaseous molecular emission with Spitzer upper limits at the 1% level in terms of line-to-continuum ratios (apart from H...

    This paper aims to clarify the association between various social capital components at the municipal level (community social capital) and two quality-of-life factors at the individual level [individual self-rated life satisfaction and self-rated health (SRH)] based on data from a nationwide social capital survey that the authors carried out in 2013 in Japan (N = 3406 in 99 municipalities). The survey covers residents in Japan between the ages of 20 and 79 years. We focus on both contextual social capital and household income inequality in terms of the Gini coefficient at the municipality level since, to the best of our knowledge, no paper has explicitly dealt with municipalities in Japan as the units of contextual social capital and the Gini. Our analyses show that the subjective life satisfaction of individuals, after controlling for socioeconomic status and health at the individual level, is associate with both an income gap and social capital at the municipal level. Every component of community social capital in this study except for generalized reciprocity, both cognitive (generalized trust, particularized trust, and particularized reciprocity), and structural (three types of group participation and daily contacts with neighbors, friends/acquaintances, and colleagues), and the Gini coefficient on earned income were associated with self-rated life satisfaction at the individual level with statistical significance. However, SRH is associated only with cognitive social capital at the community level. SRH has no significant association with structural components of community social capital or with a community income gap in terms of the Gini coefficient on personal income. Judging from the results of estimates in the study, most of the components of community social capital at the municipal level seem to play an important role in enhancing self-rated life satisfaction. Life satisfaction may be associated with the broad atmosphere of the municipal level where one

    We present measurements of the Type Ia supernova (SN) rate in galaxy clusters based on data from the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey. The cluster SN Ia rate is determined from 9 SN events in a set of 71 C4 clusters at z {le} 0.17 and 27 SN events in 492 maxBCG clusters at 0.1 {le} z {le} 0.3. We find values for the cluster SN Ia rate of (0.37{sub -0.12-0.01}{sup +0.17+0.01}) SNur h{sup 2} and (0.55{sub -0.11-0.01}{sup +0.13+0.02}) SNur h{sup 2} (SNux = 10{sup -12}L{sub x{circle_dot}}{sup -1} yr{sup -1}) in C4 and maxBCG clusters, respectively, where the quoted errors are statistical and systematic, respectively. The SN rate for early-type galaxies is found to be (0.31{sub -0.12-0.01}{sup +0.18+0.01}) SNur h{sup 2} and (0.49{sub -0.11-0.01}{sup +0.15+0.02}) SNur h{sup 2} in C4 and maxBCG clusters, respectively. The SN rate for the brightest cluster galaxies (BCG) is found to be (2.04{sub -1.11-0.04}{sup +1.99+0.07}) SNur h{sup 2} and (0.36{sub -0.30-0.01}{sup +0.84+0.01}) SNur h{sup 2} in C4 and maxBCG clusters, respectively. The ratio of the SN Ia rate in cluster early-type galaxies to that of the SN Ia rate in field early-type galaxies is 1.94{sub -0.91-0.015}{sup +1.31+0.043} and 3.02{sub -1.03-0.048}{sup +1.31+0.062}, for C4 and maxBCG clusters, respectively. The SN rate in galaxy clusters as a function of redshift, which probes the late time SN Ia delay distribution, shows only weak dependence on redshift. Combining our current measurements with previous measurements, we fit the cluster SN Ia rate data to a linear function of redshift, and find r{sub L} = [(0.49{sub -0.14}{sup +0.15}) + (0.91{sub -0.81}{sup +0.85}) x z] SNuB h{sup 2}. A comparison of the radial distribution of SNe in cluster to field early-type galaxies shows possible evidence for an enhancement of the SN rate in the cores of cluster early-type galaxies. With an observation of at most 3 hostless, intra-cluster SNe Ia, we estimate the fraction of cluster SNe that are

    Full Text Available Abstract Background The World Health Organization (WHO recommends that the role of pharmacists in low-income settings be expanded to address the increasing complexity of HIV antiretroviral (ARV and co-infection drug regimens. However, in many such settings including in India, many pharmacists and pharmacy workers are often neither well trained nor aware of the intricacies of HIV treatment. The aims of our study were; to determine the availability of ARVs, provision of ARVs, knowledge about ARVs, attitudes towards HIV-infected persons and self-perceived need for training among community-based pharmacies in an urban area of India. Methods We performed a survey of randomly selected, community-based pharmacies located in Pune, India, in 2004-2005 to determine the availability of ARVs at these pharmacies, how they were providing ARVs and their self-perceived need for training. We also assessed knowledge, attitudes and perceptions on HIV and ARVs and factors associated with stocking ARVs. Results Of 207 pharmacies included in the survey, 200 (96.6% were single, private establishments. Seventy-three (35.3% pharmacies stocked ARVs and 38 (18.4% ordered ARVs upon request. The reported median number of ARV pills that patients bought at one time was 30, a two week supply of ARVs (range: 3-240 pills. Six (2.9% pharmacy respondents reported selling non-allopathic medicines (i.e. Ayurvedic, homeopathy for HIV. Ninety (44.2% pharmacy respondents knew that ARVs cannot cure HIV, with those stocking ARVs being more likely to respond correctly (60.3% vs. 34.8%, p = 0.001. Respondents of pharmacies which stocked ARVs were also more likely to believe it was a professional obligation to provide medications to HIV-infected persons (91.8% vs. 78.8%, p = 0.007 but they were also more likely to believe that HIV-infected persons are unable to adhere to their medicines (79.5% vs. 40.9%, p Conclusion There is a high willingness to participate in HIV management among

  11. New Techniques for Relating Dynamically Close Galaxy Pairs to Merger and Accretion Rates Application to the SSRS2 Redshift Survey

    We introduce two new pair statistics, which relate close galaxy pairs to the merger and accretion rates. We demonstrate the importance of correcting these (and other) pair statistics for selection effects related to sample depth and completeness. In particular, we highlight the severe bias that can result from the use of a flux-limited survey. The first statistic, denoted N_c, gives the number of companions per galaxy, within a specified range in absolute magnitude. N_c is directly related to the galaxy merger rate. The second statistic, called L_c, gives the total luminosity in companions, per galaxy. This quantity can be used to investigate the mass accretion rate. Both N_c and L_c are related to the galaxy correlation function and luminosity function in a straightforward manner. We outline techniques which account for various selection effects, and demonstrate the success of this approach using Monte Carlo simulations. If one assumes that clustering is independent of luminosity (which is appropriate for re...

  12. The Rates and Spatial Patterns of Annual Riverbank Erosion Revealed Through Terrestrial Laser Scanner Surveys of the South River, Virginia

    O'Neal, M. A.; Pizzuto, J. E.

    2011-12-01

    Between 2006 and 2008 A.D., we completed annual surveys of two mercury-contaminated eroding banks, one forested and the other grass covered, along the gravel-bed, bedrock South River in Virginia. Gridded digital terrain models with a resolution of 0.05 m were created from bank topography data collected using a terrestrial laser scanner. The forested bank retreated nearly 1 m around two leaning trees, while elsewhere the extent of bank retreat was negligible. On the grassy bank, retreat was controlled by the creation of small overhanging clumps of turf at the top of the bank, their occasional failure, and the ultimate removal of failed debris from the bank toe. Partial autocorrelation analysis of vertically integrated bank retreat demonstrates that bank profile erosion is virtually uncorrelated at horizontal distances greater than about 1 m on both banks, a length scale of approximately 1/2 the bank height. This extensive streamwise variability suggests that widely spaced profile data cannot adequately represent bank erosion at these sites. Additional analysis of our comprehensive spatial data also indicates that traditional bank profile surveys with any spacing greater than 1 m would result in measurement errors exceeding 10%, an important conclusion for assessing annual rates of mercury loading into the South River from bank erosion. Our results suggest that 3-dimensional gridded bare-earth models of bank topography may be required to accurately measure annual bank retreat in similar river systems.

    2016-01-01

    We study a set of 3319 galaxies in the redshift interval 0.04 < z < 0.15 with far-infrared (FIR) coverage from the Herschel Stripe 82 survey (HerS), and emission-line measurements, redshifts, stellar masses and star-formation rates (SFRs) from the SDSS (DR7) MPA/JHU database. About 40% of the sample are detected in the Herschel/SPIRE 250 micron band. Total infrared (TIR) luminosities derived from HerS and ALLWISE photometry allow us to compare infrared and optical estimates of SFR with unprecedented statistics for diverse classes of galaxies. We find excellent agreement between TIR-derived and emission line-based SFRs for H II galaxies. Other classes, such as active galaxies and evolved galaxies, exhibit systematic discrepancies between optical and TIR SFRs. We demonstrate that these offsets are attributable primarily to survey biases and the large intrinsic uncertainties of the D4000- and colour-based optical calibrations used to estimate the SDSS SFRs of these galaxies. Using a classification scheme w...

    Oncogenic, high-risk human papillomavirus (HR-HPV) testing is used to evaluate women who are older than 20 years with atypical squamous cells of undetermined significance (ASC-US) and in conjunction with a screening Papanicolaou test in women older than 30 years. To evaluate the 2006 laboratory practice data from laboratories incorporating human papillomavirus (HPV) testing with the Papanicolaou test. To use the College of American Pathologists (CAP) Supplemental Questionnaire Survey for 2006 to determine laboratory practices of participants in the CAP Interlaboratory Comparison Program in Cervicovaginal Cytology. A total of 679 laboratories responded to the questionnaire. Most (73%) refer HPV testing to reference laboratories. Nine percent perform HPV testing in cytology. Forty-five percent offer low-risk HPV (LR-HPV) testing. The most common reflex is ASC-US, although HR-HPV is also offered with low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), or any other Papanicolaou test result. Digene Hybrid Capture II is the most common method. Human papilloma virus median test volumes are 55 monthly. Frequency distributions of HPV test volumes are significantly different from those found in 2003. Laboratories performing in-house testing reported significantly higher monthly HPV volumes (P HR-HPV positivity are 36.6% for ASC-US, 50.0% for atypical squamous cells, cannot exclude HSIL (ASC-H), and 4% for women 30 years of age and older in conjunction with a screening Papanicolaou test. Reference HPV testing remains the most common pattern. The most common reflex indication is for ASC-US, but HPV testing is modified locally to include a variety of scenarios. LR-HPV testing is commonly offered despite its lack of clinical significance. These data form a baseline for ongoing monitoring of HPV testing practice trends.

    This article discusses a formulation of problem mapping and preliminary surveys of total people participation in a local wind pump (LWP) water supply in term of technological implementation of renewable energy (RE) in rural-isolated areas and small-medium islands in Indonesia. The formulation was constructed in order to enhance and to promote the local product of RE across Indonesia. It was also addressed to accommodate local potencies, barriers and opportunities into a priority map. Moreover, it was designed into five aspects such as (1) local technology of the RE: a case of pilot project of the LWP; (2) environmental-cultural aspects related to global issues of energy-renewable energy; (3) potencies and barriers corresponding to local, national, regional and international contents; (4) education and training and (5) gender participation. To focus the formulation, serial preliminary surveys were conducted in five major areas, namely: (1) survey on support and barrier factors of the aspects; (2) strategic planning model, a concept A-B-G which stands for Academician-Business people-Government; (3) survey on background based knowledge on energy conservation; (4) survey on gender participation in energy conservation and (5) survey on local stakeholder involvement. Throughout the surveys, it has been notified that the concept needs to be developed to any level of its component since its elements were identified in tolerance values such as high potency value of the LWP development (95%); a strong potency of rural area application (88%); a medium background of energy, energy conservation (EC) identified in a range of 56%-72%, sufficient support from local stakeholders and gender participation.

    The rise in waterpipe tobacco smoking has been accompanied by the emergence of a diverse range of products, such as "herbal" waterpipe tobacco substitutes and electronic waterpipes. The aims of this study were to assess the extent to which emerging waterpipe products are being developed by waterpipe tobacco companies themselves, to understand the key characteristics of the main market players, and to examine the connections between producers of different product categories. In 2014, one researcher attended an international waterpipe trade exhibition in Germany, conducting a survey of products at exhibition stands, and gathering qualitative data on exhibitors and products using participant observation. Cross-tabulations and chi-square tests identified the association between waterpipe tobacco, waterpipe tobacco substitutes, and electronic waterpipe products. We thematically analyzed field notes into information about exhibitors and products. Of 97 exhibitors, 55 displayed waterpipe-related products. Of these, nearly half (45%) displayed electronic waterpipe products, 38% displayed waterpipe tobacco and 23% displayed waterpipe tobacco substitutes. There was an inverse association between the display of waterpipe tobacco and electronic waterpipe products, and a positive association between the display of waterpipe tobacco and waterpipe tobacco substitutes. We found that Japan Tobacco Inc, Philip Morris, and British American Tobacco were partnered or affiliated with exhibitors displaying waterpipe-related products. Electronic waterpipe products were the main feature of this exhibition. Waterpipe tobacco substitutes are likely to be produced by the waterpipe tobacco industry whereas electronic waterpipes are not. There is a developing interest in waterpipe-related products by transnational tobacco corporations. Further industry surveillance is warranted. © The Author 2015.

    Surveys of doctors are an important data collection method in health services research. Ways to improve response rates, minimise survey response bias and item non-response, within a given budget, have not previously been addressed in the same study. The aim of this paper is to compare the effects and costs of three different modes of survey administration in a national survey of doctors. A stratified random sample of 4.9% (2,702/54,160) of doctors undertaking clinical practice was drawn from a national directory of all doctors in Australia. Stratification was by four doctor types: general practitioners, specialists, specialists-in-training, and hospital non-specialists, and by six rural/remote categories. A three-arm parallel trial design with equal randomisation across arms was used. Doctors were randomly allocated to: online questionnaire (902); simultaneous mixed mode (a paper questionnaire and login details sent together) (900); or, sequential mixed mode (online followed by a paper questionnaire with the reminder) (900). Analysis was by intention to treat, as within each primary mode, doctors could choose either paper or online. Primary outcome measures were response rate, survey response bias, item non-response, and cost. The online mode had a response rate 12.95%, followed by the simultaneous mixed mode with 19.7%, and the sequential mixed mode with 20.7%. After adjusting for observed differences between the groups, the online mode had a 7 percentage point lower response rate compared to the simultaneous mixed mode, and a 7.7 percentage point lower response rate compared to sequential mixed mode. The difference in response rate between the sequential and simultaneous modes was not statistically significant. Both mixed modes showed evidence of response bias, whilst the characteristics of online respondents were similar to the population. However, the online mode had a higher rate of item non-response compared to both mixed modes. The total cost of the online

    The growth history of large-scale structure in the Universe is a powerful probe of the cosmological model, including the nature of dark energy. We study the growth rate of cosmic structure to redshift $z = 0.9$ using more than $162{,}000$ galaxy redshifts from the WiggleZ Dark Energy Survey. We divide the data into four redshift slices with effective redshifts $z = [0.2,0.4,0.6,0.76]$ and in each of the samples measure and model the 2-point galaxy correlation function in parallel and transverse directions to the line-of-sight. After simultaneously fitting for the galaxy bias factor we recover values for the cosmic growth rate which are consistent with our assumed $\\Lambda$CDM input cosmological model, with an accuracy of around 20% in each redshift slice. We investigate the sensitivity of our results to the details of the assumed model and the range of physical scales fitted, making close comparison with a set of N-body simulations for calibration. Our measurements are consistent with an independent power-spe...

    Full Text Available Context The rectal distension in dogs increases the rate of transitory lower esophageal sphincter relaxation considered the main factor causing gastroesophageal reflux. Objectives The aim of this study was evaluate the participation of the nitrergic pathway in the increased transitory lower esophageal sphincter relaxation rate induced by rectal distension in anesthetized dogs. Methods Male mongrel dogs (n = 21, weighing 10-15 kg, were fasted for 12 hours, with water ad libitum. Thereafter, they were anesthetized (ketamine 10 mg.Kg-1 + xylazine 20 mg.Kg-1, so as to carry out the esophageal motility evaluation protocol during 120 min. After a 30-minute basal period, the animals were randomly intravenous treated whith: saline solution 0.15M (1ml.Kg-1, L-NAME (3 mg.Kg-1, L-NAME (3 mg.Kg-1 + L-Arginine (200 mg.Kg-1, glibenclamide (1 mg.Kg-1 or methylene blue (3 mg.Kg-1. Forty-five min after these pre-treatments, the rectum was distended (rectal distension, 5 mL.Kg-1 or not (control with a latex balloon, with changes in the esophageal motility recorded over 45 min. Data were analyzed using ANOVA followed by Student Newman-Keuls test. Results In comparison to the respective control group, rectal distension induces an increase in transitory lower esophageal sphincter relaxation. Pre-treatment with L-NAME or methylene blue prevents (P<0.05 this phenomenon, which is reversible by L-Arginine plus L-NAME. However, pretreating with glibenclamide failed to abolish this process. Conclusions Therefore, these experiments suggested, that rectal distension increases transitory lower esophageal sphincter relaxation in dogs via through nitrergic pathways.

    1990-01-01

    We describe the impact of two interventions in the design of mail surveys. The interventions were devised to increase response rates and to clarify sample eligibility. To test their effectiveness, the interventions occurred at different points in each of three surveys. One intervention was a letter from the research sponsor (NASA) supporting the research. The other intervention was the inclusion of a postcard that could be used by the respondent to indicate that the questionnaire was not appropriate for him/her. The sample was drawn from the membership of a professional aerospace research society, the American Institute for Aeronautics and Astronautics (AIAA). Scientists and engineers are difficult to survey for two reasons. First, there are significant problems with the definition of scientists and engineers. Second, typically there are low response rates in surveys of this group. These two problems were found in the NASA surveys. The results indicate that the sponsor letter improved response rates under certain conditions described here. The postcards assisted in identifying non-eligible persons, particularly when the postcards accompanied a pre-survey letter. The implications for survey costs are discussed.

    Full Text Available There is research evidence that exercise and motor training are beneficial for people with Parkinson's disease (PD, and clinicians seek to implement optimal programs. This paper summarizes important factors about the nature and reporting of randomized controlled trials of exercise and/or motor training for people with PD which are likely to influence the translation of research into clinical practice. Searches identified 53 relevant trials with 90 interventions conducted for an average duration of 8.3 (SD 4.2 weeks. Most interventions were fully supervised (74% and conducted at a facility (79%. Retention rates were high with 69% of interventions retaining ≥85% of their participants; however adherence was infrequently reported, and 72% of trials did not report adverse events. Overall, the labor-intensive nature of most interventions tested in these trials and the sparse reporting of adherence and adverse events are likely to pose difficulties for therapists attempting to balance benefits and costs when selecting protocols that translate to sustainable clinical practice for people with PD.

    Full Text Available Abstract Background The participation of trainers and trainees in health research is critical to advance medical science. Overcoming barriers and enhancing incentives are essential to sustain a research culture and extend the frontiers of medical education. In this study, we investigated the roles of individual and system factors influencing trainee resident participation in health research in Enugu, south-eastern Nigeria. Methods This cross-sectional survey of trainee residents was conducted across three residency training centres in Enugu, Nigeria, between February and March, 2010. The number and speciality distribution of trainee residents were determined from personnel records at each centre. A 19-item questionnaire was used to record demographic characteristics, research training/experience, and attitudes toward and perceived barriers to health research. Data were analysed to yield frequencies, percentages and proportions. Values of p  Results The response rate was 93.2%. The respondents (n = 136 comprised 109 males and 27 females. Their mean ± standard deviation age was 35.8 ± 5.6 years (range: 25–53 years. Participation in research was significantly associated with previous research training [odds ratio (OR: 2.90; 95% confidence interval (CI: 1.35–6.25, p = 0.003, β = 22.57], previous research participation (OR: 2.21; 95% CI: 0.94–5.29, p = 0.047, β = 22.53 and research publication (OR: 2.63; 95% CI: 1.00–7.06, p = 0.03, β = 22.57.

    Nesseris, Savvas; Davis, Tamara; Parkinson, David

    2011-01-01

    We constrain the evolution of Newton's constant using the growth rate of large-scale structure measured by the WiggleZ Dark Energy Survey in the redshift range $0.1 < z < 0.9$. We use this data in two ways. Firstly we constrain the matter density of the Universe, $\\Omega_m$ (assuming General Relativity), and use this to construct a diagnostic to detect the presence of an evolving Newton's constant. Secondly we directly measure the evolution of Newton's constant, $G_{eff}$, that appears in Modified Gravity theories, without assuming General Relativity to be true. The novelty of these approaches are that, contrary to other methods, they do not require knowledge of the expansion history of the Universe, $H(z)$, making them model independent tests. Our constraints for the second derivative of Newton's constant at the present day, assuming it is slowly evolving as suggested by Big Bang Nucleosynthesis constraints, using the WiggleZ data is $\\ddotGeff(t_0)=-1.19\\pm 0.95\\cdot 10^{-20}h^2 yr^{-2}$, where $h$ is...

    We present precise measurements of the growth rate of cosmic structure for the redshift range 0.1 < z < 0.9, using redshift-space distortions in the galaxy power spectrum of the WiggleZ Dark Energy Survey. Our results, which have a precision of around 10% in four independent redshift bins, are well-fit by a flat LCDM cosmological model with matter density parameter Omega_m = 0.27. Our analysis hence indicates that this model provides a self-consistent description of the growth of cosmic structure through large-scale perturbations and the homogeneous cosmic expansion mapped by supernovae and baryon acoustic oscillations. We achieve robust results by systematically comparing our data with several different models of the quasi-linear growth of structure including empirical models, fitting formulae calibrated to N-body simulations, and perturbation theory techniques. We extract the first measurements of the power spectrum of the velocity divergence field, P_vv(k), as a function of redshift (under the assump...

  11. Unidimensional pain rating scales: a multidimensional affect and pain survey (MAPS) analysis of what they really measure.

    2002-08-01

    Pain is now regarded as 'the fifth vital sign' and patients are frequently asked to score the intensity of their pain on a numerical pain rating scale (NPRS). However, the use of a unidimensional scale is questionable in view of the belief, overwhelmingly supported by clinical experience as well as by empirical evidence from multidimensional scaling and other sources, that pain has at least two dimensions: somatosensory qualities and affect. We used a Chinese translation of the 101 descriptor multidimensional affect and pain survey (MAPS) questionnaire to determine the relative contributions of various dimensions of postoperative pain to a patient's score on a unidimensional NPRS. MAPS and NPRS were administered postoperatively to 69 patients with descending colon carcinoma who were recovering from left hemi-colectomy. Multiple linear regression revealed that the emotional pain qualities supercluster (P=0.0005) and four of its eight subclusters, anxiety, depressed mood, fear and anger, significantly (P=0.001-0.007) predicted a patient's score on the unidimensional NPRS. Notably, none of the 17 subclusters in the somatosensory pain qualities supercluster predicted NPRS scores. It may be concluded that patient scores on unidimensional pain intensity scales reflect the emotional qualities of pain much more than its sensory intensity or other qualities. Accordingly such scales are poor indicators of analgesic requirement. The results also suggest that patients' postoperative anxiety and depression are inadequately treated. Based on our findings we present six unidimensional scales that should yield a more accurate assessment of the sources of a patient's pain.

    This article examines the association between material hardships and self-rated mental health (SRMH) among older black Americans and determines whether the effect varies by race and ethnicity. Using data from the National Survey of American Life, multiple logistic regression models were specified on a sample of older white Americans (n = 289), African Americans (n = 1,135), and black Caribbean Americans (n = 377). Material hardship was measured as an index of seven items that occurred within the past year. Material hardship (odds ratio = 0.48; 95 percent confidence interval = 0.29-0.79) was associated with SRMH for both groups. None of the interactions were significant. The study concludes that material hardship may contribute to poorer SRMH among older African Americans and black Caribbean Americans. Future studies should examine these associations by using longitudinal designs, which may be better designed to confirm these results. © 2017 National Association of Social Workers.

    We investigate the star-formation rate (SFR) and stellar mass ($M_*$) relation of a star-forming (SF) galaxy sample in the XMM-LSS field to $z\\sim 3.0$ using the near-infrared data from the VISTA Deep Extragalactic Observations (VIDEO) survey. Combining VIDEO with broad-band photometry, we use the SED fitting algorithm CIGALE to derive SFRs and $M_*$ and have adapted it to account for the full photometric redshift PDF uncertainty. Applying a SF selection using the D4000 index, we find evidence for strong evolution in the normalisation of the SFR-$M_*$ relation out to $z\\sim 3$ and a roughly constant slope of (SFR $\\propto M_*^{\\alpha}$) $\\alpha=0.69\\pm0.02$ to $z\\sim 1.7$. We find this increases close to unity toward $z\\sim2.65$. Alternatively, if we apply a colour selection, we find a distinct turnover in the SFR-$M_*$ relation between $0.7\\lesssim z\\lesssim2.0$ at the high mass end, and suggest that this is due to an increased contamination from passive galaxies. We find evolution of the specific SFR $\\prop...

    Full Text Available Objectives: Clinical trials are experimental projects that include patients as subjects. A number of benefits are directly associated with clinical trials. Healthcare processes and outcomes can be improved with the help of clinical trials. This study aimed to assess the attitudes and beliefs of patients about their contribution to and enrolment in clinical trials. Methods: A cross-sectional study design was used for data collection and analysis. A questionnaire was developed with six categories to derive effective outcomes. Results: Of the 2000 participants approached to take part in the study, 1081 agreed. The majority of the study population was female, well educated, and unaware of clinical trials. Only 324 subjects (30.0% had previously agreed to participate in a clinical trial. The majority (87.1% were motivated to participate in clinical trials due to religious aspects. However, fear of any risk was the principal reason (79.8% that reduced their motivation to participate. Conclusions: The results of this study revealed that patients in Saudi Arabia have a low awareness and are less willing to participate in clinical trials. Different motivational factors and awareness programs can be used to increase patient participation in the future.

    To determine potential associations between demographic and business management factors and practice size and growth rate in rural mixed-animal veterinary practices. Cross-sectional survey. 54 mixed-animal practitioners. A cross-sectional survey (96 questions) was electronically disseminated. Responses were collected, and outcomes (number of veterinarians [NV], growth in number of veterinarians [NVG], gross practice income [GPI], growth in gross practice income [GPIG], gross practice income per veterinarian [GPIV], and growth in gross practice income per veterinarian [GPIVG]) were calculated. Bivariate analyses were performed and multivariable models created to determine associations between survey responses and outcomes of interest. Survey respondents were from mixed-animal practices, and most (46/54 [85.2%]) practiced in small communities (business manager. Typically, practices had positive mean growth in NVG (4.4%), GPIG (8.5%), and GPIVG (8.1%), but growth rate was highly variable among practices. Factors associated with growth rate included main species interest, frequency for adjusting prices, use of a marketing plan, service fee structure, and sending a client newsletter. Mixed-animal practices had a large range in size and growth rate. Economic indices were impacted by common business management practices.

  1. Impacts of Social Network on Therapeutic Community Participation: A Follow-up Survey of Data Gathered after Ya'an Earthquake.

    2015-01-01

    Full Text Available In recent years, natural disasters and the accompanying health risks have become more frequent, and rehabilitation work has become an important part of government performance. On one hand, social networks play an important role in participants' therapeutic community participation and physical & mental recovery. On the other hand, therapeutic communities with widespread participation can also contribute to community recovery after disaster.This paper described a field study in an earthquake-stricken area of Ya'an. A set of 3-stage follow-up data was obtained concerning with the villagers' participation in therapeutic community, social network status, demographic background, and other factors. The Hierarchical linear Model (HLM method was used to investigate the determinants of social network on therapeutic community participation.First, social networks have significantly impacts on the annual changes of therapeutic community participation. Second, there were obvious differences in education between groups mobilized by the self-organization and local government. However, they all exerted the mobilization force through the acquaintance networks. Third, local cadre networks of villagers could negatively influence the activities of self-organized therapeutic community, while with positively influence in government-organized therapeutic activities.This paper suggests that relevant government departments need to focus more on the reconstruction and cultivation of villagers' social network and social capital in the process of post-disaster recovery. These findings contribute to better understandings of how social networks influence therapeutic community participation, and what role local government can play in post-disaster recovery and public health improvement after natural disasters.

    We sought to evaluate the effect of pairing a mixed-mode mail and telephone methodology with a prepaid US 2.00 dollars cash incentive on response rates in a survey of Medicaid enrollees stratified by race and ethnicity. Sampling was conducted in 2 stages. The first stage consisted of a simple random sample (SRS) of Medicaid enrollees. In the second stage, American Indian, African American, Latino, Hmong, and Somali enrollees were randomly sampled. A total of 8412 enrollees were assigned randomly to receive a mail survey with no incentive or a US 2.00 dollars bill. The response rate within the SRS after the mail portion was 54% in the incentive group and 45% in the nonincentive group. Response rates increased considerably with telephone follow-ups. The incentive SRS response rate increased to 69%, and the nonincentive response rate increased to 64%. Differences between incentive conditions are more pronounced after the first mailing (P effects on response rates and cost across the different racial and ethnic strata, except for Latino enrollees. A mixed-mode mail and telephone methodology is effective for increasing response rates in a Medicaid population overall and within different racial and ethnic groupings. The effectiveness of this strategy can be enhanced, in terms of response rate and cost, by including a US 2.00 dollars prepaid incentive.

    Use of nutritional labels in choosing food is associated with healthier eating habits including lower fat intake. Current public health efforts are focusing on the revamping of nutritional labels to make them easier to read and use for the consumer. The study aims to assess the frequency of use of nutritional labels and awareness of the United States Department of Agriculture (USDA) nutritional programmes by low-income women including those participating in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) as surveyed in the National Health and Nutrition Examination Survey 2005-2006. Many low-income women do not regularly use the nutrition facts panel information on the food label and less than half had heard of the USDA Dietary Guidelines for Americans (38.9%). In multivariate logistic regression, we found that WIC participation was associated with reduced use of the nutrition facts panel in choosing food products [odds ratio (OR) 0.45, 95% confidence interval (CI) 0.22-0.91], the health claims information (OR 0.54, 95% CI 0.32-0.28) and the information on carbohydrates when deciding to buy a product (OR 0.44, 95% CI 0.20-0.97) in comparison with WIC eligible non-participants. Any intervention to improve use of nutritional labels and knowledge of the USDA's nutritional programmes needs to target low-income women, including WIC participants. Future studies should evaluate possible reasons for the low use of nutrition labels among WIC participants in comparison with eligible non-participants.

    Full Text Available Abstract Background Response rates to postal questionnaires are falling and this threatens the external validity of survey findings. We wanted to establish whether the incentive of being entered into a prize draw to win a personal digital assistant (PDA would increase the response rate for a national survey of consultant obstetricians and gynaecologists. Methods A randomised controlled trial was conducted. This involved sending a postal questionnaire to all Consultant Obstetricians and Gynaecologists in the United Kingdom. Recipients were randomised to receiving a questionnaire offering a prize draw incentive (on response or no such incentive. Results The response rate for recipients offered the prize incentive was 64% (461/716 and 62% (429/694 in the no incentive group (relative rate of response 1.04, 95% CI 0.96 – 1.13 Conclusion The offer of a prize draw incentive to win a PDA did not significantly increase response rates to a national questionnaire survey of consultant obstetricians and gynaecologists.

    Full Text Available Community involvement in mosquito management programs provides more sustainable and effective organization and service. A door to door survey in Wayne County, NC carried out by student volunteers, resulted in 60 household responses. Residents had not previously experienced outreach from the county (88%, and 95% of them thought the student door to door survey was an effective form of outreach. One third of the residents thought mosquitoes were severe where they lived, but only 9% thought they had any containers in their yard that might breed mosquitoes. Only 15% of the residents were concerned about mosquito borne diseases. These responses provide evidence that outreach and education on mosquito control and diseases were necessary steps for future mosquito control community planning.

    Mental health policy emphasises the importance of consumer participation in mental health services. To align education with policy and orient future healthcare services to active consumer involvement, the potential of academics with a lived experience of mental illness to impact on student attitudes towards consumer participation needs to be examined. A cohort comparative study was undertaken comparing attitudinal change between undergraduate nursing students undertaking two different mental health courses, one nurse-led (n  =  61) and one lived experience-led. Attitudes were measured through the Mental Health Consumer Participation Questionnaire. Within-cohort change was assessed via dependent sample t-tests, and degree of change was observed in each cohort, by comparing effect sizes. For the nurse-led course, attitudes on consumer involvement t (60)  =  -1.79, p consumer as staff t (60)  =  -4.12, p consumer capacity t (109)  =  -3.63, p consumer as staff, t (109)  =  -5.63, p consumer participation. Lived experience-led education was more beneficial in changing attitudes to consumer capacity and both types of education had similar positive effects on attitudes to consumers as staff.

    Purpose The purpose of this study was to determine whether a belief in the AIDS origin conspiracy theory is related to likelihood or fear of participation in research studies. Methods The Tuskegee Legacy Project Questionnaire was administered via random-digit-dialed telephone interview to black, white, and Hispanic participants in 4 cities in 1999 and 2000 (n = 1,133) and in 3 cities in 2003 (n = 1,162). Results In 1999, 27.8% of blacks, 23.6% of Hispanics, and 8% of whites (P ≤ .001) reported that it was “very or somewhat likely” that AIDS is “the result of a government plan to intentionally kill a certain group of people by genocide.” In 2003, 34.1% of blacks, 21.9% of Hispanics, and 8.4% of whites (P ≤ .001) reported the same. Conclusions Whereas blacks and Hispanics were more than 3 times more likely than whites to believe in this AIDS origin conspiracy theory, holding this belief was not associated with a decreased likelihood of participation in, or increased fear of participation in, biomedical research.

    Five multicentre, cross-sectional Centralized Pan-Regional Surveys on the Undertreatment of Hypercholesterolaemia (CEPHEUS) were conducted in 29 countries across Asia, Western Europe, Eastern Europe, the Middle East, and Africa. The surveys assessed the current use and efficacy of lipid-lowering drugs (LLDs) worldwide and identified possible patient and physician characteristics associated with failure to attain low-density lipoprotein cholesterol (LDL-C) goals. The aim of this analysis was to consolidate the global results from these surveys. The surveys involved patients aged ≥18 years who had been prescribed LLDs for at least 3 months without dose changes for at least 6 weeks. A single visit was scheduled for data collection, including fasting plasma lipid and glucose levels. Cardiovascular risk profile and LDL-C goal attainment were assessed according to the 2004 updated US National Cholesterol Education Program Adult Treatment Panel III guidelines. In total, 35 121 patients (mean age: 60.4 years) were included, and 90.3% had been prescribed statin monotherapy. Overall, only 49.4% of patients reached their recommended LDL-C level. LDL-C goals were attained in 54.8% (5084/9273) and 22.8% (3287/14 429) of patients were at high and very high cardiovascular risk, respectively. Factors associated with an increased likelihood of LDL-C goal attainment were lower baseline cardiovascular risk; presence of diabetes mellitus, hypertension, or history of cardiovascular disease; and treatment with simvastatin, atorvastatin, or rosuvastatin (vs. all other LLDs). LDL-C goal attainment in patients taking LLDs is suboptimal worldwide, particularly in patients at high and very high cardiovascular risk.

    We present a measurement of the volumetric Type Ia supernova (SN Ia) rate based on data from the Sloan Digital Sky Survey II (SDSS-II) Supernova Survey. The adopted sample of supernovae (SNe) includes 516 SNe Ia at redshift z \\lesssim 0.3, of which 270 (52%) are spectroscopically identified as SNe Ia. The remaining 246 SNe Ia were identified through their light curves; 113 of these objects have spectroscopic redshifts from spectra of their host galaxy, and 133 have photometric redshifts estimated from the SN light curves. Based on consideration of 87 spectroscopically confirmed non-Ia SNe discovered by the SDSS-II SN Survey, we estimate that 2.04+1.61-0.95 % of the photometric SNe Ia may be misidentified. The sample of SNe Ia used in this measurement represents an order of magnitude increase in the statistics for SN Ia rate measurements in the redshift range covered by the SDSS-II Supernova Survey. If we assume a SN Ia rate that is constant at low redshift (z < 0.15), then the SN observations can be used t...

    Full Text Available Abstract Background Population-based registries have been promoted as an effective method to improve childhood immunization rates, yet rates of registry participation in the private sector are low. We sought to describe, through a national overview, the perspectives of childhood immunization providers in private practice regarding factors associated with participation or non-participation in immunization registries. Methods Two mailed surveys, one for 264 private practices identified as registry non-participants and the other for 971 identified as registry participants, from 15 of the 31 states with population-based statewide immunization registries. Frequency distributions were calculated separately for non-participants and participants regarding the physician-reported factors that influenced decisions related to registry participation. Pearson chi-square tests of independence were used to assess associations among categorical variables. Results Overall response rate was 62% (N = 756. Among non-participants, easy access to records of vaccines provided at other sites (N = 101, 68% and printable immunization records (N = 82, 55% were most often cited as "very important" potential benefits of a registry, while the most commonly cited barriers to participation were too much cost/staff time (N = 36, 38% and that the practice has its own system for recording and monitoring immunizations (N = 35, 37%. Among registry participants, most reported using the registry to input data on vaccines administered (N = 326, 87% and to review immunization records of individual patients (N = 302, 81%. A minority reported using it to assess their practice's immunization coverage (N = 110, 29% or generate reminder/recall notices (N = 54, 14%. Few participants reported experiencing "significant" problems with the registry; the most often cited was cost/staff time to use the registry (N = 71, 20%.

    2009-05-01

    This study investigated factors influencing ongoing participation in employee development activities. A multiple-indicator structural equation model building on the theory of planned behavior and prior employee development literature was tested with a survey across 4 organizations on 2 occasions. The model uses reactions to past participation and past supportiveness of the social and organizational environment as indirect antecedents of participation, filtered through their impact on attitudes and behavioral intentions toward future participation. Learning goal orientation also influenced attitudes toward participation. Whereas personal control over participation and higher levels of voluntariness were negatively related to participation, intentions to participate and availability of opportunities arose as strong predictors of higher participation rates. Many significant hypothesized paths were found, and 85% of the variance in participation was explained by the model variables. Increasing employee awareness of opportunities and managing positive attitudes toward those opportunities are recommended as key factors for increasing participation rates.

    Tai Chi Chuan (TCC) is a traditional Chinese medicine practice and martial art with biopsychosocial aspects. This study aimed to examine the impact of participation in TCC on multiple domains of Quality of Life (QoL) and to assess the involvement of the psychological factors of self-efficacy, Locus of Control (LoC) and Hope in these effects. A total of 68 participants from the general community (13 males and 55 females) aged between 18 and 68 (M=43.55 years) and not currently suffering from a mental or physical illness took part in the study. It was found that TCC participants, as a group, scored significantly better than those in sedentary (book club) and active (gym exercise) control conditions on Psychological and Physical QoL, and that the Physical QoL benefits of TCC continue to accrue with years of practice. The three psychological factors were shown to variously mediate (self-efficacy) and moderate (internal LoC and Hope) this latter relationship. Whilst the results bear limitations (in particular small sample sizes), it is hoped that these findings will encourage further research into TCC, and consideration of TCC as part of the range of treatment options available in community-based mental and physical health management.

    The purpose of this study was to compare characteristics of youth who participate in the choking game alone versus those who participate in a group. Lifetime prevalence estimates were obtained from the 2011 (n = 5682) and 2013 (n = 15 150) Oregon Healthy Teens survey. The 2011 and 2013 data sets were merged (N = 20 832) to compare youth who participate alone versus those who participate in a group in the choking game. Multivariate modeling was conducted to examine individual characteristics of young people who engaged in the choking game alone versus those who engaged in the game in a group. In 2011, 3.8% of eighth-grade participants reported a lifetime prevalence of choking game participation; 3.7% reported lifetime prevalence of participation in 2013. In the merged 2011/2013 data set, 17.6% (n = 93) of choking game participants indicated that they had participated alone. Compared with those who reported participating in a group, youth who participated alone had significantly higher rates of suicide contemplation (odds ratio: 4.58; P game are a particularly high risk group, exhibiting substantially higher rates of suicidal ideation and poorer mental health compared with youth who participate in the choking game in a group.

    We present a measurement of the volumetric Type Ia supernova (SN Ia) rate based on data from the Sloan Digital Sky Survey II (SDSS-II) Supernova Survey. The adopted sample of supernovae (SNe) includes 516 SNe Ia at redshift z {approx}< 0.3, of which 270 (52%) are spectroscopically identified as SNe Ia. The remaining 246 SNe Ia were identified through their light curves; 113 of these objects have spectroscopic redshifts from spectra of their host galaxy, and 133 have photometric redshifts estimated from the SN light curves. Based on consideration of 87 spectroscopically confirmed non-Ia SNe discovered by the SDSS-II SN Survey, we estimate that 2.04{sub -0.95}{sup +1.61}% of the photometric SNe Ia may be misidentified. The sample of SNe Ia used in this measurement represents an order of magnitude increase in the statistics for SN Ia rate measurements in the redshift range covered by the SDSS-II Supernova Survey. If we assume a SN Ia rate that is constant at low redshift (z < 0.15), then the SN observations can be used to infer a value of the SN rate of r{sub V} = (2.69{sub -0.30-0.01}{sup +0.34+0.21}) x 10{sup -5} SNe yr{sup -1} Mpc{sup -3} (H{sub 0}/(70 km s{sup -1} Mpc{sup -1})){sup 3} at a mean redshift of {approx} 0.12, based on 79 SNe Ia of which 72 are spectroscopically confirmed. However, the large sample of SNe Ia included in this study allows us to place constraints on the redshift dependence of the SN Ia rate based on the SDSS-II Supernova Survey data alone. Fitting a power-law model of the SN rate evolution, r{sub V} (z) = A{sub p} x ((1+z)/(1+z{sub 0})){sup {nu}}, over the redshift range 0.0 < z < 0.3 with z{sub 0} = 0.21, results in A{sub p} = (3.43{sub -0.15}{sup +0.15}) x 10{sup -5} SNe yr{sup -1} Mpc{sup -3} (H{sub 0}/(70 km s{sup -1} Mpc{sup -1})){sup 3} and {nu} = 2.04{sub -0.89}{sup +0.90}.

    We report the results of our statistical study of the POINT-AGAPE CNe catalogue. The first Sloan $r'$ and $i'$ analysis of the MMRD relationship in M31 is performed using the resulting POINT-AGAPE CN catalogue. Good fits are produced to the MMRD in the two filters. However, we are unable to verify the $t_{15}$ relationship for either Sloan filter. The subsequent analysis of our automated CN detection pipeline has provided us with the most thorough knowledge of the completeness of a CN survey to-date. In addition, the large field of view of the survey has permitted us to probe the outburst rate well into the galactic disk, unlike previous CCD imaging surveys. Using this analysis we are able to probe the CN distribution of M31 and evaluate the global nova rate. Using models of the galactic surface brightness of M31, we show that the observed CN distribution consists of a separate bulge and disk population. We also show that the M31 bulge CN eruption rate per unit $r'$ flux is more than five times greater than t...

    A strandplain at the downdrift side of the wave-dominated Catumbela delta (Angola) includes distinguishable deposits with very high natural radioactivity (up to 0.44 microSv/hour). In order to establish the geometry of these sedimentary units and understand their genetic processes, dose rate surveys were performed with the portable equipment Rados RDS-40WE. In addition, grain-size distribution, heavy-mineral composition and gamma-ray mass spectra of the high dose rate deposits were analysed. High dose rate values are found in ribbon units aligned parallel to the shoreline, which are a few tens of meters wide and up to approximately 3 km long. These units reflect the concentration of Th-bearing grains in coastal deposits enriched in heavy minerals. An integrated analysis of the high dose rate ribbons in GIS environment with aerial photography and topographic maps suggests that parts of the high dose rate units formed during the last two centuries may be related with the erosion of older shoreline deposits, due to updrift displacements of the Catumbela river outlet and recycling of shoreline accumulations with downdrift deposition. Simple gamma-ray surveys carried out with a portable detector can unravel depositional units characterised by significant enrichment in heavy-mineral grains that are likely to correspond to key events in the evolution of wave-dominated accumulations. The location of such deposits should be taken into account when planning future work using more expensive or time-consuming techniques.

    Full Text Available Abstract Background Cardiac rehabilitation has a beneficial effect on the prognosis and quality of life of cardiac patients, and has been found to be cost-effective. This report describes a comprehensive and low cost educational intervention designed to increase the attendance at cardiac rehabilitation programs of patients who have undergone coronary artery bypass graft surgery. Methods/Design A controlled prospective intervention trial. The control arm comprised 520 patients who underwent coronary artery bypass graft surgery between January 2004 and May 2005 in five medical centers across Israel. This group received no additional treatment beyond usual care. The intervention arm comprised 504 patients recruited from the same cardiothoracic departments between June 2005 and November 2006. This group received oral and written explanations about the advantages of participating in cardiac rehabilitation programs and a telephone call two weeks after hospital discharge intended to further encourage their enrollment. The medical staff attended a one-hour seminar on cardiac rehabilitation. In addition, it was recommended that referral to cardiac rehabilitation be added to the letter of discharge from the hospital. Both study groups were interviewed before surgery and one-year post surgery. A one-year post-operative interview assessed factors affecting patient attendance at cardiac rehabilitation programs, as well as the structure and content of the cardiac rehabilitation programs attended. Anthropometric parameters were measured at pre- and post-operative interviews;- and medical information was obtained from patient medical records. The effect of cardiac rehabilitation on one- and three-year mortality was assessed. Discussion We report a low cost yet comprehensive intervention designed to increase cardiac rehabilitation participation by raising both patient and medical staff awareness to the potential benefits of cardiac rehabilitation.

    We report on the results of a search for radio transients between 115 and 190\\,MHz with the LOw Frequency ARray (LOFAR). Four different fields have been monitored with observational cadences between 15 minutes and several months. These fields have been chosen among the Medium Deep fields observed by the optical survey PanSTARRS. A total of 15 observing runs were performed giving a total survey area of 2275 deg$^2$. We analysed our data using standard LOFAR tools and searched for radio transients using the LOFAR Transient Pipeline (TraP). No credible radio transient candidate has been detected in our survey; however, it enables us to set upper limits on the surface density of radio transient sources at low radio frequencies, where little is yet known compared to frequencies above 1 GHz. To do this we used two new statistical methods. One is free of assumptions on the flux distribution of the sources, while the other assumes a power-law distribution in flux and sets more stringent constraints on the snapshot su...

    Greenfader, Christa Mulker; Miller, Elizabeth B

    Data from the Head Start Impact Study (N = 4,442) were used to test for differences between Spanish-speaking Dual Language Learners (DLLs) and monolingual English-speaking children in: (1) Head Start attendance rates when randomly assigned admission; and (2) quality ratings of other early childhood education (ECE) programs attended when not randomly assigned admission to Head Start. Logistic regressions showed that Spanish-speaking DLL children randomly assigned a spot in Head Start were more likely than monolingual-English learners to attend. Further, Spanish-speaking DLLs not randomly assigned a spot in Head Start were more likely to attend higher-quality ECE centers than non-DLL children. Policy implications are discussed, suggesting that, if given access, Spanish-speaking DLL families will take advantage of quality ECE programs.

    Full Text Available BACKGROUND: A substantial proportion of men who have sex with men (MSM in the United States remain unvaccinated against hepatitis B. We sought to understand which factors are associated with vaccination among HIV-negative MSM. METHODOLOGY/PRINCIPAL FINDINGS: Data were from a 2010 web-based survey of adult MSM. We calculated the prevalence of self-reported hepatitis B vaccination among 1,052 HIV-negative or HIV-untested men who knew their hepatitis B vaccination status, and used multivariate logistic regression to determine associated factors. 679 (64.5% MSM reported being vaccinated. Younger men were more likely to report being vaccinated than older men, and there was a significant interaction between age and history of hepatitis B testing. Men with at least some college education were at least 2.1 times as likely to be vaccinated as men with a high school education or less (95% CI = 1.4-3.1. Provider recommendation for vaccination (aOR = 4.2, 95% CI = 2.4-7.4 was also significantly associated with receipt of vaccination. CONCLUSIONS/SIGNIFICANCE: Providers should assess sexual histories of male patients and offer those patients with male sex partners testing for hepatitis infection and vaccinate susceptible patients. There may be particular opportunities for screening and vaccination among older and more socioeconomically disadvantaged MSM.

  3. A survey of nuclear ribosomal internal transcribed spacer substitution rates across angiosperms: an approximate molecular clock with life history effects

    2006-04-01

    Full Text Available Abstract Background A full understanding of the patterns and processes of biological diversification requires the dating of evolutionary events, yet the fossil record is inadequate for most lineages under study. Alternatively, a molecular clock approach, in which DNA or amino acid substitution rates are calibrated with fossils or geological/climatic events, can provide indirect estimates of clade ages and diversification rates. The utility of this approach depends on the rate constancy of molecular evolution at a genetic locus across time and across lineages. Although the nuclear ribosomal internal transcribed spacer region (nrITS is increasingly being used to infer clade ages in plants, little is known about the sources or magnitude of variation in its substitution rate. Here, we systematically review the literature to assess substitution rate variation in nrITS among angiosperms, and we evaluate possible correlates of the variation. Results We summarize 28 independently calibrated nrITS substitution rates ranging from 0.38 × 10-9 to 8.34 × 10-9 substitutions/site/yr. We find that herbaceous lineages have substitution rates almost twice as high as woody plants, on average. We do not find any among-lineage phylogenetic constraint to the rates, or any effect of the type of calibration used. Within life history categories, both the magnitude of the rates and the variance among rates tend to decrease with calibration age. Conclusion Angiosperm nrITS substitution rates vary by approximately an order of magnitude, and some of this variation can be attributed to life history categories. We make cautious recommendations for the use of nrITS as an approximate plant molecular clock, including an outline of more appropriate phylogenetic methodology and caveats against over interpretation of results. We also suggest that for lineages with independent calibrations, much of the variation in nrITS substitution rates may come from uncertainty in calibration

    We report on the results of a search for radio transients between 115 and 190 MHz with the LOw-Frequency ARray (LOFAR). Four fields have been monitored with cadences between 15 min and several months. A total of 151 images were obtained, giving a total survey area of 2275 deg(2). We analysed our data using standard LOFAR tools and searched for radio transients using the LOFAR Transients Pipeline. No credible radio transient candidate has been detected; however, we are able to set upper limits on the surface density of radio transient sources at low radio frequencies. We also show that low-frequency radio surveys are more sensitive to steep-spectrum coherent transient sources than GHz radio surveys. We used two new statistical methods to determine the upper limits on the transient surface density. One is free of assumptions on the flux distribution of the sources, while the other assumes a power-law distribution in flux and sets more stringent constraints on the transient surface density. Both of these methods provide better constraints than the approach used in previous works. The best value for the upper limit we can set for the transient surface density, using the method assuming a power-law flux distribution, is 1.3 × 10(-3) deg(-2) for transients brighter than 0.3 Jy with a time-scale of 15 min, at a frequency of 150 MHz. We also calculated for the first time upper limits for the transient surface density for transients of different time-scales. We find that the results can differ by orders of magnitude from previously reported, simplified estimates.

    We study a set of 3319 galaxies in the redshift interval 0.04 neglected in existing studies. We also study the capabilities of infrared selection of star-forming galaxies. FIR selection reveals a substantial population of galaxies dominated by cold dust which are missed by the long-wavelength WISE bands. Our results demonstrate that Herschel large-area surveys offer the means to construct large, relatively complete samples of local star-forming galaxies with accurate estimates of SFR that can be used to study the interplay between nuclear activity and star formation.

    To evaluate obstetrics and gynecology resident interest and participation in global health experiences and elucidate factors associated with resident expectation for involvement. A voluntary, anonymous survey was administered to U.S. obstetrics and gynecology residents before the 2015 Council on Resident Education in Obstetrics and Gynecology in-training examination. The 23-item survey gathered demographic data and queried resident interest and participation in global health. Factors associated with resident expectation for participation in global health were analyzed by Pearson χ tests. Of the 5,005 eligible examinees administered the survey, 4,929 completed at least a portion of the survey for a response rate of 98.5%. Global health was rated as "somewhat important" or "very important" by 96.3% (3,761/3,904) of residents. "Educational opportunity" (69.2%) and "humanitarian effort" (17.7%) were cited as the two most important aspects of a global health experience. Residents with prior global health experience rated the importance of global health more highly and had an increased expectation for future participation. Global health electives were arranged by residency programs for 18.0% (747/4,155) of respondents, by residents themselves as an elective for 44.0% (1,828/4,155), and as a noncredit experience during vacation time for 36.4% (1,514/4,155) of respondents. Female gender, nonpartnered status, no children, prior global health experience, and intention to incorporate global health in future practice were associated with expectations for a global health experience. Most obstetrics and gynecology residents rate a global health experience as somewhat or very important, and participation before or during residency increases the perceived importance of global health and the likelihood of expectation for future participation. A majority of residents report arranging their own elective or using vacation time to participate, suggesting that residency programs have

    Using health plan membership as a proxy for employee retention, the objective of this study was to examine whether use of health promotion programs was associated with employee retention. Propensity score weighted generalized linear regression models were used to estimate the association between telephonic programs or health risk surveys and retention. Analyses were conducted with six study samples based on type of program participation. Retention rates were highest for employees with either telephonic program activity or health risk surveys and lowest for employees who did not participate in any interventions. Participants ranged from 71% more likely to 5% less likely to remain with their employers compared with nonparticipants, depending on the sample used in analyses. Using health promotion programs in combination with health risk surveys may lead to improvements in employee retention.

  9. The Extended HST Supernova Survey: The Rate of SNe Ia at z>1.4 Remains Low

    Dahlen, Tomas; Riess, Adam G

    2008-01-01

    We use the HST ACS imaging of the two GOODS fields during Cycles 11, 12, and 13 to derive the Type Ia supernova rate in four redshift intervals in the range 0.21.4 supports our previous result that there is a drop in the Type Ia supernova rate at high redshift, suggesting a long time delay between the formation of the progenitor star and the explosion of the supernova. If described by a simple one-parameter model, we find a characteristic delay time of 2-3 Gyr. However, a number of recent results based on e.g., low redshift supernova samples and supernova host galaxy properties suggest that the supernova delay time distribution is bimodal. In this model, a major fraction of the Type Ia supernova rate is 'prompt' and follows the star formation rate, while a smaller fraction of the rate has a long delay time, making this channel proportional to mass. While our results are fully consistent with the bimodal model at low redshifts, the low rate we find at z>1.4 appears to contradict these results. Models that corr...

  10. Monitoring water quality in Toronto's urban stormwater ponds: Assessing participation rates and data quality of water sampling by citizen scientists in the FreshWater Watch.

    2017-08-15

    From 2013 to 2015, citizen scientist volunteers in Toronto, Canada were trained to collect and analyze water quality in urban stormwater ponds. This volunteer sampling was part of the research program, FreshWater Watch (FWW), which aimed to standardize urban water sampling efforts from around the globe. We held training sessions for new volunteers twice yearly and trained a total of 111 volunteers. Over the course of project, ~30% of volunteers participated by collecting water quality data after the training session with 124 individual sampling events at 29 unique locations in Toronto, Canada. A few highly engaged volunteers were most active, with 50% of the samples collected by 5% of trainees. Stormwater ponds generally have poor water quality demonstrated by elevated phosphate concentrations (~30μg/L), nitrate (~427μg/L), and turbidity relative to Canadian water quality standards. Compared to other urban waterbodies in the global program, nutrient concentrations in Toronto's urban stormwater ponds were lower, while turbidity was not markedly different. Toronto FWW (FWW-TO) data was comparable to that measured by standard lab analyses and matched results from previous studies of stormwater ponds in Toronto. Combining observational and chemical data acquired by citizen scientists, macrophyte dominated ponds had lower phosphate concentrations while phytoplankton dominated ponds had lower nitrate concentrations, which indicates a potentially important and unstudied role of internal biogeochemical processes on pond nutrient dynamics. This experience in the FWW demonstrates the capabilities and constraints of citizen science when applied to water quality sampling. While analytical limits on in-field analyses produce higher uncertainty in water quality measurements of individual sites, rapid data collection is possible but depends on the motivation and engagement of the group of volunteers. Ongoing efforts in citizen science will thus need to address sampling effort

    Aims. The assessment of limitations in social capacities can be done with the Mini-ICF-APP, a rating scale built in reference to the International Classification of Functioning, Disability and Health (ICF). The aim of this study was to assess the reliability and the convergent validity of the Italian version of this scale. Methods. We recruited 120 consecutive patients diagnosed with schizophrenia, major depression, bipolar I disorder and anxiety disorders. Included measures were the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression Scale (CGI-S), the Personal and Social Performance Scale (PSP) and the Social and Occupational Functioning Assessment Scale (SOFAS). Results. The median CGI-S and BPRS scores were 5 and 16.5. Mean Mini-ICF-APP total score was 18.1. Schizophrenics' Mini-ICF-APP score was higher, while that of anxious patients was lower than in the other diagnoses. Intra-class correlations (ICC) revealed a significant inter-rater agreement for total score (ICC 0.987) and for each item of the Mini-ICF-APP. The test-retest agreement was also highly significant (ICC 0.993). The total score of the Mini-ICF-APP obtained good negative correlations with PSP (r s = -0.767) and with SOFAS scores (r s = -0.790). The distribution items of the Mini-ICF-APP showed some skewness, indicating that self-care (item 12) and mobility (item 13) were amply preserved in most patients. The Mini-ICF-APP total score was significantly correlated with both CGI-S (r s = 0.777) and BPRS (r s = 0.729). Conclusions. As a short instrument, the Mini-ICF-APP scale seems to be well suited to everyday psychiatric practice as a means of monitoring changes in psychosocial functioning, in particular in schizophrenic patients.

  13. Consistency of the growth rate in different environments with the 6dF Galaxy Survey: measurement of the void-galaxy & galaxy-galaxy correlation functions

    2016-01-01

    We present a new test of gravitational physics by comparing the growth rate of cosmic structure measured around voids with that measured around galaxies in the same large-scale structure dataset, the low-redshift 6-degree Field Galaxy Survey. By fitting a self-consistent Redshift Space Distortion model to the 2D galaxy-galaxy and void-galaxy correlation functions, we recover growth rate values f\\sigma_8 = 0.36 \\pm 0.06 and 0.39 \\pm 0.11, respectively. The environmental-dependence of cosmological statistics can potentially discriminate between modified-gravity scenarios which modulate the growth rate as a function of scale or environment and test the underlying assumptions of homogeneity and isotropy.

    Full Text Available The rates and modalities of healthcare services utilization for migrant population may differ from natives, since the health needs of the former are influenced by some factors such as health status, self-perceived needs, healthseeking behavior, language barriers and cultural differences. Only scarce and often conflicting data have been published so far on migrants’ utilization of healthcare services in Europe, and even less data are available on emergency departments (EDs. The aim of this cross-sectional study was to compare utilization rates and modalities of presentation to the large urban ED of the University Hospital of Parma, Italy (averaging 85,000 visits per year, by Italian native and foreign-born populations during 2008-2012. Throughout the study period 424,466 ED visits were recorded, 64,435 (15.4% of which by foreign-born patients. A significant difference between utilization rates was observed for all the triage-codes, with higher rates for foreign-born low-acuity codes (green plus white codes: 87.5 vs 73.9, P<0.0001 and lower rates for high-acuity codes (yellow plus red codes: 12.5 vs 26.1%, P<0.0001. The utilization rate was 253.9 visits per 1000 inhabitants for the Italian-native group and 309.7 per 1000 for the foreign-born group (odds ratio 1.23; 95% CI: 1.01-1.48; P=0.034. Different modalities of presentation were also observed, with a high rate of selfreferrals (82.3 vs 71.4%, P<0.001. The results of this study suggest that a better knowledge of available Italian healthcare services among immigrants is advisable and should be encouraged.

    We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 0.9 SNe. Finding 8 +/- 1 cluster SNe Ia, we determine a SN Ia rate of 0.50 +0.23-0.19 (stat) +0.10-0.09 (sys) SNuB (SNuB = 10^-12 SNe L_{sun,B}^-1 yr^-1). In units of stellar mass, this translates to 0.36 +0.16-0.13 (stat) +0.07-0.06 (sys) SNuM (SNuM = 10^-12 SNe M_sun^-1 yr^-1). This represents a factor of approximately 5 +/- 2 increase over measurements of the cluster rate at z < 0.2. We parameterize the late-time SN Ia delay time distribution with a power law (proportional to t^s). Under the assumption of a cluster formation redshift of z_f = 3, our rate measurement in combination with lower-redshift cluster SN Ia rates constrains s = -1.31 +0.55-0.40, consistent with measurements of the delay time distribution in the field. This measurement is also consistent with the value of s ~ -1 typically expected for the "double degenerate" SN Ia progenitor scenario, and inconsistent with some models for the "single degenerat...

    This study determined evidence for digit preference in self-reports of smoking in the Second National Health and Nutrition Examination Survey (NHANES II). Subjects were 4275 adult smokers. Self-reports of smoking showed a marked degree of digit preference, with the vast majority of smokers reporting in multiples of 10 cigarettes per day. When number per day was compared to an objective measure of smoking exposure (carboxyhemoglobin; n = 2070) the distribution was found to be significantly assymetrical. Analysis of the distribution of COHb and various levels of number per day indicates that the differences in distribution are not due to variability in COHb. Heavier smokers, Caucasians, and those with less education were more likely to report a digit preference than lighter smokers. African-Americans, and those with more education. Results suggest that self-reports of number of cigarettes per day may be biased towards round numbers (particularly 20 cigarettes per day). Implications for assessment of smoking behavior are discussed.

    Meta Salud was a community health worker-facilitated intervention for the prevention of noncommunicable diseases in Northern Mexico. This analysis examined changes in perceived health, eating habits, and physical activity immediately and 3 months after the intervention. The impact on the resulting behavioral and psychological factors are reported. This was a nonrandomized intervention study with 1 baseline and 2 post-intervention follow-ups. Outcome evaluation consisted of anthropometric measurements, laboratory tests, and a lifestyle questionnaire. The most consistent patterns were increases in metabolic equivalent of task values expended per day from baseline to post-intervention (difference = 996; 95% confidence interval [CI]: 81 to 1,912) and to 3-month follow-up (difference = 1,073; 95% CI: 119 to 2,028); greater likelihood of meeting Centers for Disease Control and Prevention daily exercise recommendations, with an increase from 49% to 60% at post-intervention (OR: 1.6, 95% CI: 1.0 to 2.4) and 63% at follow-up (OR: 1.7, 95% CI: 1.7 to 2.7); lesser likelihood for consuming whole milk, from 38% to 59% (OR: 2.9, 95% CI: 1.8 to 4.7); fewer daily servings of packaged foods, from 0.72 to 0.57 (difference = -0.16; 95% CI: -0.28 to -0.03); fewer days of poor mental health, from 9.3 to 5.8 (difference = -3.4; 95% CI: -5.1 to -1.7); and greater likelihood for reporting good self-rated health, from 41% to 54% post-intervention (OR: 2.1, 95% CI: 1.3 to 3.6) and 57% at follow-up (OR: 2.5, 95% CI: 1.5 to 4.4). Changes in other outcomes, although in the expected direction of association, were not statistically significant. The study identified important strategies for making feasible dietary changes in the consumption of whole milk, sugary drinks, and packaged foods, yet there is still a need to identify strategies for improving consumption of healthy foods. There was stronger evidence for ways of improving physical activity as opposed to other outcome measures

    The use of smart phones is increasing in the world. This excessive use, especially in the last two decades, has created too much concern on the effects of emitted electromagnetic fields and specific absorption rate on human health. In this descriptive-analytical study of the electric field resulting from smart phones of Samsung and Nokia by portable measuring device, electromagnetic field, Model HI-3603-VDT/VLF, were measured. Then, head absorption rate was calculated in these two mobiles by ICNIRP equation. Finally, the comparison of specific absorption rate, especially between Samsung and Nokia smart phones, was conducted by T-Test statistics analysis. The mean of electric field for Samsung and Nokia smart mobile phones was obtained 1.8 ±0.19 v/m  and 2.23±0.39 v/m , respectively, while the range of the electric field was obtained as 1.56-2.21 v/m and 1.69-2.89 v/m for them, respectively. The mean of specific absorption rate in Samsung and Nokia was obtained 0.002 ± 0.0005 W/Kg and 0.0041±0.0013 W/Kg at the frequency of 900 MHz and 0.004±0.001 W/Kg and 0.0062±0.0002 W/Kg at the frequency of 1800 MHz respectively. The ratio of mean electronic field to guidance in the Samsung mobile phone at the frequency of 900 MHz and 1800 MHz was 4.36% and 3.34%, while was 5.62% and 4.31% in the Nokia mobile phone, respectively. The ratio of mean head specific absorption rate in smart mobile phones of Samsung and Nokia in the guidance level at the frequency of 900 was 0.15% and 0.25%, respectively, while was 0.23 %and 0.38% at the frequency of 1800 MHz, respectively. The rate of specific absorption of Nokia smart  mobile phones at the frequencies of 900 and 1800 MHz  was significantly higher than Samsung (p value Nokia smart phones is higher than Samsung smart mobile phone.

    Many older adults are using technology regularly, but the vast majority still rate their technology skills as poor or average,reflecting their low usage of less-familiar items such as tablet computers. Despite moves toward increasing the use of ICT in the care, rehabilitation, and monitoring of older adults, baseline use of such devices is low. Further study is required to investigate how people's attitudes toward and experience with ICT influence its utility in clinical practice

    The radius and surface composition of an exploding massive star, as well as the explosion energy per unit mass, can be measured using early UV observations of core collapse supernovae (SNe). We present the first results from a simultaneous GALEX/PTF search for early UV emission from SNe. Six Type II SNe and one Type II superluminous SN (SLSN-II) are clearly detected in the GALEX NUV data. We compare our detection rate with theoretical estimates based on early, shock-cooling UV light curves calculated from models that fit existing Swift and GALEX observations well, combined with volumetric SN rates. We find that our observations are in good agreement with calculated rates assuming that red supergiants (RSGs) explode with fiducial radii of 500 R_solar, explosion energies of 10^51 erg, and ejecta masses of 10 M_solar. Exploding blue supergiants and Wolf-Rayet stars are poorly constrained. We describe how such observations can be used to derive the progenitor radius, surface composition and explosion energy per u...

  11. The relationship between sleep time and self-rated health: an analysis based on Italian survey data

    Full Text Available Background: a growing and broadly discussed literature has shown that the relationship between sleep duration and health is not linear. Not only are insomnia and insufficient sleep harmful to one’s health, but excessive sleep too is also not beneficial. This study tests the association between selfrated state of health and the duration and pattern of sleep: we discuss the losses and costs in terms of quality of life deriving from excessive sleep time.Methods: we use an ordered probit specification, applied to the Italian Survey on the Use of Time (sample of Italians aged fifteen and over who keep a diary for a working day.Results: we show that greater sleep duration is negatively correlated both with self-reported state of health and with self-reported health satisfaction, while respondents’ subjective perceptions of too much and too little sleep are associated with health conditions in the usual u-shaped way.Conclusions: the negative impact of long sleep on self-reported health is confirmed. However, the effect of short sleep on health conditions is positive, while a measure of decreasing sleep quality - comprising number of interruptions of sleep, insomnia and napping - is correlated to some extent with decreasing health. The public health consequences are still to be explored: the potential gains from sleep restriction are substantial, but little is known about the causal link or the risks. Further research is needed before taking policy decisions.

    European cancer survival rates vary widely. System factors, including whether or not primary care physicians (PCPs) are gatekeepers, may account for some of these differences. This study explores where patients who may have cancer are likely to present for medical care in different European countries, and how probability of presentation to a primary care clinician correlates with cancer survival rates. Seventy-eight PCPs in a range of European countries assessed four vignettes representing patients who might have cancer, and consensus groups agreed how likely those patients were to present to different clinicians in their own countries. These data were compared with national cancer survival rates. A total of 14 countries. Consensus groups of PCPs. Probability of initial presentation to a PCP for four clinical vignettes. There was no significant correlation between overall national 1-year relative cancer survival rates and the probability of initial presentation to a PCP (r  = -0.16, 95% CI -0.39 to 0.08). Within that there was large variation depending on the type of cancer, with a significantly poorer lung cancer survival in countries where patients were more likely to initially consult a PCP (lung r = -0.57, 95% CI -0.83 to -0.12; ovary: r = -0.13, 95% CI -0.57 to 0.38; breast r = 0.14, 95% CI -0.36 to 0.58; bowel: r = 0.20, 95% CI -0.31 to 0.62). There were wide variations in the degree of gatekeeping between countries, with no simple binary model as to whether or not a country has a "PCP-as-gatekeeper" system. While there was case-by-case variation, there was no overall evidence of a link between a higher probability of initial consultation with a PCP and poorer cancer survival.

    Healthcare organizations with an ethical culture experience higher levels of employee productivity, less staff turnover, better levels of patient safety, resource and cost savings, and higher levels of patient satisfaction. Employees' perceptions of the ethics of their organization are considered a good indicator of the ethics culture. How employees rate the ethics of their organization is not well understood. Previous research has identified a number of attributes that are salient to employees' perceptions in this area. However, little is known about how employees synthesize their perceptions of these attributes to rate the ethics of their organization. Without this knowledge, managers have little specific information to act on to improve practices that would in turn improve employees' perceptions of their organization's ethics. For this study, we used data from Department of Veterans Affairs' (VA) 2014 IntegratedEthics@ Staff Survey administered to Veterans Health Administration (VHA) staff. We used multivariate regression analyses to investigate how VHA employees weigh their perceptions of eight attributes of an ethical organization to inform an overall rating of the ethics of their organization. We found that employee perceptions of fairness, clarity of expectations, accountability, and leadership's prioritization of ethics had the strongest associations with the overall rating. In addition, employees disproportionately weighed their positive perceptions in determining their overall rating. Therefore, a strategy to improve employees' perceptions of these attributes could potentially have the greatest marginal return on investment with respect to improving employees' perceptions of the ethics of an organization.

    Community-academic partnerships (CAPs) improve the research process, outcomes, and yield benefits for the community and researchers. This exploratory study examined factors important in community stakeholders' decision to participate in CAPs. Autism spectrum disorder (ASD) community stakeholders, previously contacted to participate in a CAP (n = 18), completed the 15-item Decision to Participate Questionnaire (DPQ). The DPQ assessed reasons for participating or declining participation in the ASD CAP. CAP participants rated networking with other providers, fit of collaboration with agency philosophy, and opportunity for future training/consultations as factors more important in their decision to participate in the ASD CAP than nonparticipants. Nonparticipants reported the number of requests to participate in research as more important in their decision to decline participation than participants. Findings reveal important factors in community stakeholders' decision to participate in CAPs that may provide guidance on increasing community engagement in CAPs and help close the science-to-service gap.

    Full Text Available The effects of verbal and/or numerical labeling and number of categories on the measurement of latent variables in web surveys are addressed. Data were collected online in a quota sample of the German adult population (N = 741. A randomized 2x2x2 experimental design was applied, with variation of the number of categories, as well as of verbal and numerical labeling, using an abbreviated version of the Positive and Negative Affect Schedule (PANAS. Experimental manipulation of the rating scale formats resulted in an effect on measurement model testing and reliability, as well as on factorial and convergent validity. In addition, measurement invariance between several rating scale formats was limited. With the five category end verbalized and fully labeled seven category formats, acceptable results for all measurement quality metrics could be obtained.

    To understand cosmic mass assembly in the Universe at early epochs, we primarily rely on measurements of stellar mass and star formation rate of distant galaxies. In this paper, we present stellar masses and star formation rates of six high-redshift ($2.8\\leq z \\leq 5.7$) dusty, star-forming galaxies (DSFGs) that are strongly gravitationally lensed by foreground galaxies. These sources were first discovered by the South Pole Telescope (SPT) at millimeter wavelengths and all have spectroscopic redshifts and robust lens models derived from ALMA observations. We have conducted follow-up observations, obtaining multi-wavelength imaging data, using {\\it HST}, {\\it Spitzer}, {\\it Herschel} and the Atacama Pathfinder EXperiment (APEX). We use the high-resolution {\\it HST}/WFC3 images to disentangle the background source from the foreground lens in {\\it Spitzer}/IRAC data. The detections and upper limits provide important constraints on the spectral energy distributions (SEDs) for these DSFGs, yielding stellar masses...

    We present a new measurement of the volumetric rate of Type Ia supernova up to a redshift of 1.7, using the Hubble Space Telescope (HST) GOODS data combined with an additional HST dataset covering the North GOODS field collected in 2004. We employ a novel technique that does not require spectroscopic data for identifying Type Ia supernovae (although spectroscopic measurements of redshifts are used for over half the sample); instead we employ a Bayesian approach using only photometric data to calculate the probability that an object is a Type Ia supernova. This Bayesian technique can easily be modified to incorporate improved priors on supernova properties, and it is well-suited for future high-statistics supernovae searches in which spectroscopic follow up of all candidates will be impractical. Here, the method is validated on both ground- and space-based supernova data having some spectroscopic follow up. We combine our volumetric rate measurements with low redshift supernova data, and fit to a number of pos...

  2. Analysis of four studies in a comparative framework reveals: health linkage consent rates on British cohort studies higher than on UK household panel surveys.

    2014-11-27

    A number of cohort studies and longitudinal household panel studies in Great Britain have asked for consent to link survey data to administrative health data. We explore commonalities and differences in the process of collecting consent, achieved consent rates and biases in consent with respect to socio-demographic, socio-economic and health characteristics. We hypothesise that British cohort studies which are rooted within the health sciences achieve higher consent rates than the UK household longitudinal studies which are rooted within the social sciences. By contrast, the lack of a specific health focus in household panel studies means there may be less selectivity in consent, in particular, with respect to health characteristics. Survey designs and protocols for collecting informed consent to health record linkage on two British cohort studies and two UK household panel studies are systematically compared. Multivariate statistical analysis is then performed on information from one cohort and two household panel studies that share a great deal of the data linkage protocol but vary according to study branding, survey design and study population. We find that consent is higher in the British cohort studies than in the UK household panel studies, and is higher the more health-focused the study is. There are no systematic patterns of consent bias across the studies and where effects exist within a study or study type they tend to be small. Minority ethnic groups will be underrepresented in record linkage studies on the basis of all three studies. Systematic analysis of three studies in a comparative framework suggests that the factors associated with consent are idiosyncratic to the study. Analysis of linked health data is needed to establish whether selectivity in consent means the resulting research databases suffer from any biases that ought to be considered.

    Background We investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data. Methods Using data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM]), 242 newly diagnosed with DM (new-DM), and 474 previously diagnosed with DM (known-DM), we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication) and control rate of hypertension (blood pressure [BP] <130/80 mm Hg). Results The prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively) compared with non-DM adults (26.2%). Compared to non-DM, awareness (85.7%, P<0.001) and treatment (97.0%, P=0.020) rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%), compared to non-DM (35.1%, P<0.001) and known-DM (33.3%, P=0.004). Control rate among treated subjects was also lower in new-DM (25.2%), compared to non-DM (68.4%, P<0.0001) and known-DM (39.9%, P<0.0001). Conclusion Higher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

  5. A Simple Calculation in Service of Constraining the Rate of FU Orionis Outburst Events from Photometric Monitoring Surveys

    CERN Document Server

    Hillenbrand, Lynne A

    2015-01-01

    An enigmatic and rare type of young stellar object is the FU Orionis class. The members are interpreted as "outbursting," that is, currently in a state of enhanced accretion by several orders of magnitude relative to the more modest disk-to-star accretion rates measured in typical T Tauri stars. They are key to our understanding of the history of stellar mass assembly and pre-main sequence evolution, as well as critical to consider in the chemical and physical evolution of the circumstellar environment -- where planets form. A common supposition is that *all* T Tauri stars undergo repeated such outbursts, more frequently in their earlier evolutionary stages when the disks are more massive, so as to build up the requisite amount of stellar mass on the required time scale. However, the actual data supporting this traditional picture of episodically enhanced disk accretion are limited, and the observational properties of the known sample of FU Ori objects quite diverse. To improve our understanding of these rare...

    IgG antibodies to Toxoplasma gondii were detected in, March-April 2004, in 65.8% (95% confidence interval, 60.8-70.8%) of 342 systematically sampled subjects 5-90 years of age (87.5% of the eligible) living in a rural settlement in Amazonia, with a seroconversion rate of 9% over 1 year of follow-up of 99 seronegative subjects. Multiple logistic regression analysis identified age as the only significant independent predictor of seropositivity at the baseline. Each additional year of age increases the odds of being seropositive by 6%, and 76.8% of the subjects are expected to be seropositive at 30 years of age. A single high-prevalence spatial cluster, comprising 11.9% of the seropositive subjects, was detected in the area; households in the cluster were less likely to have dogs as pets and their heads had a lower education level, when compared with households located outside the cluster. The challenges for preventing human toxoplasmosis in tropical rural settings are discussed.

    Full Text Available In this study we analyzed gender inequalities in labour force participation of the two Asian Countries namely Pakistan and Malaysia. Gender inequalities in labour market are analyzed and updated using recent time series data of 2005 to 2009. The data are drawn from different sources including various Integrated Household Surveys, Labour Force Surveys, Economic Surveys and Labour Force Survey Reports of the two countries. The results indicate significant gender differences in the labour force participation rate and status of employment of the two countries. Labour force participation rate of female is 20% and the male is 71% in Pakistan whereas in Malaysia the participation rate of female is 46% and the male is 80%. Furthermore women of age group 25 to 29 and women of age group 35 to 39 years are the most productive age intervals in Malaysia and Pakistan, respectively. The general increase in the participation of youth in Malaysia are due to rapid expansion of educational facilities, equal access of female to every level of education, delayed marriages and reduced fertility rate while increased participation of the interval group of 35 to 39 is due to the induction of married women in the labour market in Pakistan.

    Full Text Available Introduction: Sleep disturbances are common in adolescents and adversely affect performance, social contact and susceptibility to stress. We investigated the hypothesis of a relationship between sleep and health-related quality of life (HRQoL, and applied self- and proxy ratings. Materials and Methods: The sample comprised 92 adolescents aged 11-17 years. All participants and their parents completed a HRQoL measure and the Sleep Disturbance Scale for Children (SDSC. Children with SDSC T-scores above the normal range (above 60 were classified as poor sleepers. Results: According to self- and proxy ratings, good sleepers reported significantly higher HRQoL than poor sleepers. Sleep disturbances were significantly higher and HRQoL significantly lower in self- compared to parental ratings. Parent-child agreement was higher for subscales measuring observable aspects. Girls experienced significantly stronger sleep disturbances and lower self-rated HRQoL than boys. Discussion: Our findings support the positive relationship of sleep and HRQoL. Furthermore, parents significantly underestimate sleep disturbances and overestimate HRQoL in their children.

    Aim: "Late motherhood" is associated with greater perinatal risks but the term lacks precise definition. We present an approach to determine what "late motherhood" associated with "high risk" is, based on parity and preterm birth rate. Materials and Methods: Using data from the German Perinatal Survey of 1998-2000 we analysed preterm birth rates in women with zero, one, or two previous live births. We compared groups of "late" mothers (with high preterm birth rates) with "control" groups of younger women (with relatively low preterm birth rates). Data of 208 342 women were analysed. For women with zero (one; two) previous live births, the "control" group included women aged 22-26 (27-31; 29-33) years. Women in the "late motherhood" group were aged > 33 (> 35; > 38) years. Results: The "late motherhood" groups defined in this way were also at higher risk of adverse perinatal events other than preterm birth. For women with zero (one; two) previous live births, normal cephalic presentation occurred in 89 % (92.7 %; 93.3 %) in the "control" group, but only in 84.5 % (90 %; 90.4 %) in the "late motherhood" group. The mode of delivery was spontaneous or at most requiring manual help in 71.3 % (83.4 %; 85.8 %) in the "control" group, but only in 51.4 % (72.2 %; 76.4 %) in the "late motherhood" group. Five-minute APGAR scores were likewise worse for neonates of "late" mothers and the proportion with a birth weight ≤ 2499 g was greater. Conclusion: "Late motherhood" that is associated with greater perinatal risks can be defined based on parity and preterm birth rate.

    Europe has a ‘problem’; it is becoming a ‘less cultural continent’ as fewer Europeans are ‘engaging in cultural activities’. This conclusion has been reached due to the findings of the latest cross national cultural participation survey. This paper questions the existence of this ‘problem......’ and instead suggests that there is a shared problematisation across Europe sustained by common discursive archaeology that employs various discursive strands in relation to a dominant institutional discourse. The argument is that the ‘problem’ of ‘non-participation’ legitimates a ‘solution’ that predates its...

    We describe the Multi-Epoch Nearby Cluster Survey, designed to measure the cluster Type Ia supernova (SN Ia) rate in a sample of 57 X-ray selected galaxy clusters, with redshifts of 0.05 < z < 0.15. Utilizing our real-time analysis pipeline, we spectroscopically confirmed twenty-three cluster SNe Ia, four of which were intracluster events. Using our deep Canada-France-Hawaii Telescope/MegaCam imaging, we measured total stellar luminosities in each of our galaxy clusters, and we performed detailed supernova (SN) detection efficiency simulations. Bringing these ingredients together, we measure an overall cluster SN Ia rate within R{sub 200} (1 Mpc) of 0.042{sup +0.012}{sub -0.010}{sup +0.010}{sub -0.008} SNuM (0.049{sup +0.016}{sub -0.014}{sup +0.005}{sub -0.004} SNuM) and an SN Ia rate within red-sequence galaxies of 0.041{sup +0.015}{sub -0.015}{sup +0.005}{sub -0.010} SNuM (0.041{sup +0.019}{sub -0.015}{sup +0.005}{sub -0.004} SNuM). The red-sequence SN Ia rate is consistent with published rates in early-type/elliptical galaxies in the 'field'. Using our red-sequence SN Ia rate, and other cluster SN measurements in early-type galaxies up to z {approx} 1, we derive the late-time (>2 Gyr) delay time distribution (DTD) of SN Ia assuming a cluster early-type galaxy star formation epoch of z{sub f} = 3. Assuming a power-law form for the DTD, {Psi}(t){proportional_to}t{sup s} , we find s = -1.62 {+-} 0.54. This result is consistent with predictions for the double degenerate SN Ia progenitor scenario (s {approx} -1) and is also in line with recent calculations for the double detonation explosion mechanism (s {approx} -2). The most recent calculations of the single degenerate scenario DTD predicts an order-of-magnitude drop-off in SN Ia rate {approx}6-7 Gyr after stellar formation, and the observed cluster rates cannot rule this out.

  16. What does a "superstitious" person believe? Impressions of participants.

    2003-10-01

    The questions in surveys in which superstitious belief is examined are based on the researcher or researchers' definitions of superstition and not on participants' definitions. In the present study, 170 undergraduates filled out 2 surveys. In the 1st survey, they were asked to rate 28 possible beliefs of a fictitious person described as "superstitious." In the 2nd survey, they were asked to rate their own level of belief for the same items. An analysis revealed several different factors describing different types of beliefs held by the fictitious person. Ratings for the fictitious person were greatest for socially transmitted beliefs (e.g., black cats, rabbits' feet) or idiosyncratic rituals related to luck and chance, followed by belief in the paranormal (e.g., ghosts), spiritualism (e.g., reincarnation), or psi (e.g., telepathy). Religious beliefs were rated as not being descriptive of the fictitious superstitious person. However, an analysis of the participants' own beliefs revealed that those with higher levels of religious belief also tended to be superstitious and believed in the paranormal.

    We examined the role of gender, family, lifestyle and psychological factors in self-rated health. Cross-sectional study. A total of 970 randomly selected students from 11 secondary schools in Lima and Callao, Peru, participated in 2014. Self-rated health was measured with a single item: 'In general, how would you rate your health?' Responses were arranged along a five-point Likert-type scale: 'excellent', 'very good', 'good', 'fair' and 'poor'. The outcome variable was dichotomised as 'good' (excellent, very good or good) or 'poor/fair' (poor or fair). We calculated adjusted ORs (AORs) and 95% CIs for poor/fair self-rated health using multivariate logistic regression analyses at 3-graded levels. 32.5% of the respondents had fair/poor self-rated health, 23.7% of the total males and 40.0% of the total female samples. Males were less likely to have poor/fair self-rated health (AOR 0.61; CI 0.41 to 0.91). Poor family support strongly increased the likelihood of having poor/fair self-rated health (no support, (AOR 3.15; CI 1.63 to 6.09); low support, (AOR 2.50; CI 1.29 to 4.85)). The other associated variables were missed meals due to a shortage of food (AOR 1.97; CI 1.15 to 3.36), television watching during leisure time (AOR 1.70; CI 1.09 to 2.67), low physical activity (AOR 1.49; CI 1.03 to 2.15), school absenteeism (AOR 1.54; CI 1.03 to 2.31) and perceived life satisfaction (AOR 0.28; CI 0.15 to 0.25). Gender, missing meals due to a shortage of food, family support, physical activity and life satisfaction influenced self-rated health among adolescents in Peru. Interventions that focus on promoting physical activity for at least 1 h each day for 3 or more days per week, food security and strengthening supportive family roles may improve self-rated health during adolescence.

    Data regarding hypertension in elderly adults with chronic kidney disease (CKD) remains limited. This study aimed to assess the epidemiological characteristics of hypertension in elderly adults with CKD using data from a nationwide survey. A nationwide, multicenter, cross-sectional study with a large sample. The Survey of Prevalence, Awareness, and Treatment Rates in Chronic Kidney Disease Patients with Hypertension in China (PATRIOTIC). Participants in PATRIOTIC (aged≥60; n=2,414). Trained physicians measured blood pressure (BP) using a standard protocol with a mercury sphygmomanometer at the time of admission. The prevalence, awareness, and treatment of hypertension in elderly adults with CKD were 82.0%, 90.7%, and 87.3%, respectively. The control of hypertension at BP less than 140/90 mmHg was 29.6% and at BP less than 130/80 mmHg it was 12.1%. No significant differences were noted in the prevalence, awareness, treatment, or control of hypertension in individuals with CKD divided into the age groups of 60 to 69, 70 to 79, and 80 and older (P>.05). With increasing age, the proportion of isolated systolic hypertension in elderly adults with CKD with uncontrolled hypertension increased (P=.02). Obesity (P=.01), CKD Stages 4 and 5 (Phypertension in elderly adults with CKD, using the goal of BP less than 140/90 mmHg. The prevalence of hypertension in elderly adults in China with CKD is high, and its control is poor. Most elderly adults with CKD with uncontrolled hypertension have systolic hypertension. Obesity, CKD Stages 4 and 5, and diabetes mellitus were adversely associated with greater uncontrolled hypertension in elderly adults with CKD. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

    Despite that heart rate (HR) control is one of the guideline-recommended treatment goals for heart failure (HF) patients, implementation has been painstakingly slow. Therefore, it would be important to identify patients who have not yet achieved their target heart rates and assess possible underlying reasons as to why the target rates are not met. The survey of HR in patients with HF in Sweden (HR-HF survey) is an investigator-initiated, prospective, multicenter, observational longitudinal study designed to investigate the state of the art in the control of HR in HF and to explore potential underlying mechanisms for suboptimal HR control with focus on awareness of and adherence to guidelines for HR control among physicians who focus on the contributing role of beta-blockers (BBs). In 734 HF patients the mean HR was 68 ± 12 beats per minute (bpm) (37.2% of the patients had a HR >70 bpm). Patients with HF with reduced ejection fraction (HFrEF) (n = 425) had the highest HR (70 ± 13 bpm, with 42% >70 bpm), followed by HF with preserved ejection fraction and HF with mid-range ejection fraction. Atrial fibrillation, irrespective of HF type, had higher HR than sinus rhythm. A similar pattern was observed with BB treatment. Moreover, non-achievement of the recommended target HR (bpm) in HFrEF and sinus rhythm was unrelated to age, sex, cardiovascular risk factors, cardiovascular diseases, and comorbidities, but was related to EF and the clinical decision of the physician. Approximately 50% of the physicians considered a HR of >70 bpm optimal and an equal number considered a HR of >70 bpm too high, but without recommending further action. Furthermore, suboptimal HR control cannot be attributed to the use of BBs because there was neither a difference in use of BBs nor an interaction with BBs for HR >70 bpm compared with HR bpm. Suboptimal control of HR was noted in HFrEF with sinus rhythm, which appeared to be attributable to physician decision making rather

    Differences are found among the effects of family structure to different labor groups' employment participation through literature research. Based on CGSS2008 data, the article explores the influence of family structure to labor participation rate of the youth and the mechanism of the effect. Through the Probit and the IV Probit model, empirical analysis found that: Overall, the family structure of multi-generation has inhibitory effect to the youth's labor participation, while degree of influence of family structure to the male youth employment is higher than that of young women; seen from the household registration, influence of family structure to rural youth employment participation is higher than that of city youth labor force participation. Value the importance of the family characteristic differences of youth groups and carry out the employment promotion measures should be the focuses for government to help youth employment.%家庭结构对青年群体劳动参与率有影响。基于CGSS2008数据,通过Probit和IV Probit模型实证分析发现:从总体看,多代同堂的家庭结构对青年群体的劳动参与产生抑制作用,而男性青年的就业参与受家庭结构的影响程度却高于女性青年劳动参与的影响程度;从户籍看,农村青年的就业参与受家庭结构的影响程度高于城市青年劳动参与的影响程度。重视青年群体的家庭特征差异,配套实行就业促进措施,是我国政府解决青年群体就业难的着力点。
