A Systematic Replication of a Survey of School Administrators’ and Teachers’ Views Of Discipline Referrals for Students With and Without Disabilities

This study investigated time lost to office discipline referrals (ODRs), systematically replicating a prior study (Church, 2015) in rural school districts. An on-line survey asked administrators, general education, and special education teachers in four county districts for: a) demographic information; 2) estimated minutes lost to ODRs generally, specific ODR types, and for students with (SWD) or without disabilities (not SWD); and, 3) whether the respondent’s school implemented School-wide Positive Behavior Supports (SWPBS). ODRs generally took 16.9 minutes. Special Education teachers’ time (mean 23.6 min.), was Lost time was affected by ODR type (aggression, noncompliance, disruption mean 23 min.; not finishing work, inappropriate language, cell phone use mean 12.33 min.) and disability (SWD mean 20.2 min; Not SWD mean 15.17 min). Respondents reporting SWPBs had longer ODR times (mean 19.13 min.) than respondents without SWPBS (mean 16.77 min.). Implications for future research and the evaluation of SWPBS programs were discussed

Do healthcare services behave as complex systems? Analysis of patterns of attendance and implications for service delivery

Background: The science of complex systems has been proposed as a way of understanding health services and the demand for them, but there is little quantitative evidence to support this. We analysed patterns of healthcare use in different urgent care settings to see if they showed two characteristic statistical features of complex systems: heavy-tailed distributions (including the inverse power law) and generative burst patterns. Methods: We conducted three linked studies. In study 1 we analysed the distribution of number of contacts per patient with an urgent care service in two settings: emergency department (ED) and primary care out-of-hours (PCOOH) services. We hypothesised that these distributions should be heavy-tailed (inverse power law or log-normal) in keeping with typical complex systems. In study 2 we analysed the distribution of bursts of contact with urgent care services by individuals: correlated bursts of activity occur in complex systems and represent a mechanism by which overall heavy-tailed distributions arise. In study 3 we replicated the approach of study 1 using data systematically identified from published sources. Results: Study 1 involved data from a PCOOH service in Scotland (725,000) adults, 1.1 million contacts) and an ED in New Zealand (60,000 adults, 98,000 contacts). The total number of contacts per individual in each dataset was statistically indistinguishable from an inverse power law (p &gt; 0.05) above 4 contacts for the PCOOH data and 3 contacts for the ED data. Study 2 found the distribution of contact bursts closely followed a heavy-tailed distribution (p &lt; 0.008), indicating the presence of correlated bursts. Study 3 identified data from 17 studies across 8 countries and found distributions similar to study 1 in all of them. Conclusions: Urgent healthcare use displays characteristic statistical features of large complex systems. These studies provide strong quantitative evidence that healthcare services behave as complex systems and have important implications for urgent care. Interventions to manage demand must address drivers for consultation across the whole system: focusing on only the highest users (in the tail of the distribution) will have limited impact on efficiency. Bursts of attendance - and ways to shorten them - represent promising targets for managing demand.</p

Who Wears the MAGA Hat? Racial Beliefs and Faith in Trump

On the basis of a 2019 YouGov survey of white respondents (n = 734), the impact of racial beliefs on support for Donald Trump was explored. The analysis revealed that in addition to racial resentment, white nationalism—a desire to keep the United States white demographically and culturally—was strongly related to faith in Trump. Analyses based on a 2019 Amazon Mechanical Turk survey yielded similar results and also showed that white nationalism increased willingness to wear a MAGA hat. Future research on the political consequences of racial beliefs should focus on what whites think not only of blacks but also of themselves

Factors Influencing the Selection of Precision Farming Information Sources by Cotton Producers

Precision farming information demanded by cotton producers is provided by various suppliers, including consultants, farm input dealerships, University Extension systems, and media sources. Factors associated with the decisions to select among information sources to search for precision farming information are analyzed using a multivariate probit regression accounting for correlation among the different selection decisions. Factors influencing these decisions are age, education, and income. These findings should be valuable to precision farming information providers who may be able to better meet their target clientele needs.Extension, information-source-use decisions, media, multivariate probit, precision agriculture technologies, private sources, Farm Management, Teaching/Communication/Extension/Profession,

Misfit and milestones: structural elaboration and capability reinforcement in the evolution of entrepreneurial top management teams

We examine how "top management team (TMT) misfit," or discrepancies between the TMT's functional roles and the qualifications of the managers who fill those roles, affects the evolution of TMT composition and structure in a longitudinal study of entrepreneurial ventures. We distinguish two types of misfit--overqualification and underqualification-- and study how each is associated with TMT changes. We further consider the moderating effect of firm development. Results reveal that underqualified TMTs hire new managers to reinforce existing capabilities whereas overqualified TMTs elaborate their role structures. However, achieving developmental milestones (i.e., obtaining venture capital funding and staging an initial public offering) is a critical contingency to TMT change: absent these milestones, firms neither hire new managers nor add roles, even when they seemingly need to do so. These findings contribute to knowledge of how TMTs and new ventures evolve by underscoring the importance of simultaneously attending to TMT composition and structure

Pessary versus cerclage versus expectant management for cervical dilation with visible membranes in the second trimester.

OBJECTIVE: We evaluated pessary for dilated cervix and exposed membranes for prolonging pregnancy compared to cerclage or expectant management. METHODS: Multicenter retrospective cohort study of women, 15-24 weeks, singleton pregnancies, dilated cervix ≥2 cm and exposed membranes. Women received pessary, cerclage or expectant management. Primary outcome was gestational age (GA) at delivery. Secondary outcomes were time until delivery, preterm premature rupture of membranes (PPROM) and neonatal survival. RESULTS: About 112 women met study criteria; 9 - pessary, 85 - cerclage and 18 - expectant management. Mean GA at delivery was 22.9 ± 4.5 weeks with pessary, 29.2 ± 7.5 weeks with cerclage and 25.6 ± 6.7 weeks with expectant management (p = 0.015). Time until delivery was 16.1 ± 18.9 days in the pessary group, 61.7 ± 48.2 days in the cerclage group and 26.8 ± 33.4 days in the expectant group (p \u3c 0.001). PPROM occurred less frequently and neonatal survival increased in women with cerclage. There was a significant difference in all the perinatal outcomes with cerclage compared with either pessary or expectant management. CONCLUSIONS: Perinatal outcomes with pessary were not superior to expectant management in women with dilated cervix with exposed membranes in the second trimester in this small retrospective cohort

Designing and analysing feasibility studies of complex interventions: challenges related to assessing stop/go criteria

Randomised controlled trials (RCTs) are time-consuming and costly so funders often require evidence of feasibility before they will fund large scale trials1. Feasibility studies can provide invaluable evidence relating to the practicalities of conducting large RCTs and can improve their likelihood of success. However, conducting feasibility studies of complex interventions and deciding whether or not to proceed to a full RCT, is not always straightforward. We will present the challenges encountered during the design and analysis of two feasibility studies: OBI (Optimised Behavioural Intervention for avoidant chronic low back pain patients) and MIDSHIPS (Multicentre Intervention Designed for Self-Harm using Interpersonal Problem Solving) and discuss the steps taken to overcome them. Recruiting and treating participants in a limited number of centres, with few therapists, is a complex challenge for both of these feasibility studies and crucial to determining their success; we will present the lessons learnt from our experience. We will also discuss the impact of missing data on our ability to assess stop/go criteria with respect to proof-of-concept. Estimating follow-up questionnaire response rates is an important objective in both studies, hence we will discuss the methods employed to maximise data collection and present our approach for providing robust estimates of response rates for the phase III trials
