Improving response to an establishment survey through the use of web-push data collection methods

ABSTRACT

The web-push method has been shown to increase web response rates in general public surveys. Response rates from two waves of the Emergency Medical Services for Children Program’s Performance Measures Survey, a state-administered establishment survey, were compared to determine if the second wave's revised, centralized implementation strategy improved response rates and consistency across states. The centralized strategy included the web-push design; a carefully timed contacts; and a three-month timeline. The results of the centralized web-push method included a higher overall response rate for a three-month period (81.0% compared to 56.6%) as well as greater consistency in results across states.     

Still connecting the dots: An investigation into infants' attentional bias to threat using an eye-tracking task

An attentional bias toward threat has been theorized to be a normative aspect of infants' threat and safety learning, and an indicator of risk for internalizing psychopathology in older populations. To date, only four studies have examined this bias using the dot-probe task in infancy and the findings are mixed. We extended the literature by examining patterns of attention to threat in a culturally and linguistically diverse sample of infants aged 5–11 months old (N = 151) using all measures previously employed in the infant dot-probe literature. Given that an attentional bias toward threat is associated with higher risk of developing anxiety disorders later in life, we also examined how negative affect—an early correlate of later anxiety disorders—is related to attentional bias toward threat in infancy. This study was the first to use a consistent measure of negative affect across the whole sample. An eye-tracking dot-probe task was used to examine attentional bias toward threat (i.e., angry faces) relative to positive (i.e., happy faces) stimuli. Results showed that an attention bias to threat was not characteristic of infants at this age, and negative affect did not moderate the putative relationship between attention and emotional faces (angry, happy). These findings therefore suggest that attention biases to socio-emotional threat may not have emerged by 11 months old.     

A Review of Eight Statistics Software Packages for General Use

Eight statistical software packages for general use by non-statisticians are reviewed. The packages are GraphPad Prism, InStat, ISP, NCSS, SigmaStat, Statistix, Statmost, and Winks. Summary tables of statistical capabilities and “usability” features are followed by discussions of each package. Discussions include system requirements, data import capabilities, statistical capabilities, and user interface. Recommendations, based on user needs and sophistication, are presented following the reviews.     

The Concept(s) of Trust in Late Modernity,the Relevance of Realist Social Theory

In this paper, we argue that trust is an important aspect of social reality, one that realist social theory has paid little attention to but which clearly resonates with a realist social ontology. Furthermore, the emergence of an interest in trust in specific subject fields such as organization theory indicates the growing significance of issues of trust as market liberalism has developed. As such, the emergence of an interest in trust provides support for Archer's characterisation of late modernity in The Reflexive Imperative (2012) as a period of heterogeneity and greater incongruity. Commenting on this provides an opportunity to discuss the issue of habit in relation to trust and also the importance of the analysis of integration as a means to explain problems of trust. The commentary draws on examples from finance.     

'Get Up. Stand Up.' Riding to resilience on a surfboard

Government policies sanctioning the systematic removal of Australian Aboriginal children from their families ended in the 1970s. However, trauma associated with removal remains active in the present day for those removed and their offspring, contributing to the pernicious interlinked set of health and social problems afflicting most Aboriginal communities. Child abuse and neglect are an important avenue of inter-generational transmission of trauma leaving many Aboriginal children challenge-averse and vulnerable to social disadvantage, substance abuse and mental health problems in later life. Child protection and health services have a poor record engaging and providing effective interventions to Aboriginal Australians. Sunset Surfers is a learn-to-surf programme targeting a disadvantaged urban neighbourhood with a high proportion of Aboriginal families. Qualitative evaluation shows that participants experienced positive effect associated with the challenging activity of learning to surf, allowing for reframing of children's negative beliefs about challenge. By providing an appropriate balance of challenge and support, and encouraging physical activity, Sunset Surfers represents a holistic, preventative approach to a pernicious array of social and health problems.     

RCBDs with a control

The randomized complete block designs, RCBDs, are among the most popular of block designs for comparing a set of experimental treatments. The question of this design's effectiveness when one of the treatments is a control is examined here. Optimality ranges are established for the RBCD in terms of the strength of interest in control comparisons. It is found that if the control treatment is of secondary interest, the RCBD, when not best, is typically near best. This is not so when comparisons with the control are of greater interest than those among the other treatments.     

Multiplicity: discussion points from the Statisticians in the Pharmaceutical Industry multiplicity expert group

In May 2012, the Committee of Health and Medicinal Products issued a concept paper on the need to review the points to consider document on multiplicity issues in clinical trials. In preparation for the release of the updated guidance document, Statisticians in the Pharmaceutical Industry held a one‐day expert group meeting in January 2013. Topics debated included multiplicity and the drug development process, the usefulness and limitations of newly developed strategies to deal with multiplicity, multiplicity issues arising from interim decisions and multiregional development, and the need for simultaneous confidence intervals (CIs) corresponding to multiple test procedures. A clear message from the meeting was that multiplicity adjustments need to be considered when the intention is to make a formal statement about efficacy or safety based on hypothesis tests. Statisticians have a key role when designing studies to assess what adjustment really means in the context of the research being conducted. More thought during the planning phase needs to be given to multiplicity adjustments for secondary endpoints given these are increasing in importance in differentiating products in the market place. No consensus was reached on the role of simultaneous CIs in the context of superiority trials. It was argued that unadjusted intervals should be employed as the primary purpose of the intervals is estimation, while the purpose of hypothesis testing is to formally establish an effect. The opposing view was that CIs should correspond to the test decision whenever possible. Copyright © 2013 John Wiley & Sons, Ltd.     

What Risks Are People Concerned About

An unusual questionnaire was used to explore what risks concern laypeople. It asked respondents to list, in their own words, as many risks of personal concern as they could. They then selected the five risks of greatest concern and answered a set of specific questions about each. A coding scheme was developed for categorizing these responses and was shown to have good reliability. The questionnaire was administered to a heterogeneous convenience sample of subjects. They reported a very broad range of risks of concern, which differed in plausible ways as a function of their gender and age. Females and student-age subjects were generally more concerned about the environment, whereas males and older subjects were more likely to mention health and safety risks. Both the extent of the risk-reduction actions that they reported and their expressed willingness to pay for future risk reductions were greater for risk that presented a direct personal threat (e.g., health risks) than for risks that posed a diffuse threat to the environment or to people in general (e.g., pollution). Respondents perceived themselves as bearing primary responsibility for managing threats to their own health, but generally saw government as bearing a heavier responsibility for managing environmental risks (especially for pollutants) and war. The questionnaire instrument and coding structure developed for this work are well-suited to a variety of future research applications. They provide a way to identify the risks that concern lay groups, as well as to track the evolution of those concerns over time.     

The Changing Institutional Context of Low Fertility

Using data for 1960–97 for 22 low fertility countries, we document a dramatic change in the association of fertility levels to women's levels of labor force participation. Until the 1980s, this association had been strongly negative. However, during the 1980s itbecame positive, and since 1990 strongly positive. We also document an emerging positive association of the country-level total fertility ratio (TFR) and nonmarital ratio (e.g., the proportion of births to unmarried women). We argue that these transformed associations reflect societal level responses that, in some contexts, have eased the incompatibility between mother and worker roles, and loosened the link betweenmarriage and childbearing. These arguments imply that societal responses to mother/worker incompatibility exert substantial influence on fertility levels in low fertility countries.
