Abstract Background In Bangladesh, about 30 percent of the total births a woman on average have (2.3 births) are unwanted. Reduction in unwanted births is very important for family wellbeing, and control of rapid population growth. This reduction requires in-depth knowledge about the factors associated with the change in unwanted childbearing. This study examines the contributions of population structure, external factors that is family planning programmes, and their interaction to the change in the proportion of women having unwanted birth during 2004 ̶ 2007, 2007 ̶ 2011 and 2011 ̶ 2014. Methods This study uses the notion of standardization approach for measuring the effects of family planning programmes and non-programme factors on unwanted childbearing. Using Bangladesh Demographic and Health Survey data, we employ both aggregate and detailed three-fold decomposition technique to decompose the changes in the proportion having unwanted birth into the contributions of the three different factors. In decomposing the changes, we use logistic regression estimates. Results About 10.3 percent women are found to have unwanted birth in 2014. This percentage remains almost unchanged during 2004−2007, but declines significantly during 2007−2011 and 2011−2014. Population structure exerts significant reducing effect on proportion having unwanted birth during all the study periods, while external factors exerts significant negative effect only during 2011−2014. Interaction effect is found non-significant during all the study periods. All the factors found significantly associated with unwanted childbearing in logistic regression analysis do not show significant effect on its changes in detailed decomposition analysis. Structural effects of respondent’s age at marriage and education are found significantly negative during all the study periods. Conclusions In Bangladesh, significant reducing effect of population structure amid non-declining family planning programmes reduces the proportion having unwanted birth, while simultaneous reducing effects of structure and family planning programmes during a period result in a more pronounced decline. Substantial decline in women marrying before age 18 and having no education is likely to play a vital role in resulting a population structure that may have significant reducing effect on the proportion having unwanted birth.

The Proctor test method, as specified in AASHTO T134 and ASTM D558, continues to play a vital role in design and construction quality control for soil-cement materials. However, neither test method establishes a methodology or standardized protocols to characterize the effects of time delay between cement addition and compaction, also known as compaction delay. Compaction delay has been well documented to have a notably negative effect on compactability, compressive strength, and overall performance of soil-cement materials, but specification tools to address this behavior are not prevalent. This paper aims to demonstrate the extent of compaction delay effects on several soil-cement mixtures used in Mississippi and to present recommended new test method protocols for AASHTO T134 to characterize compaction delay effects. Data presented showed that not all soil-cement mixtures are sensitive to compaction delay, but some mixtures can be very sensitive and lead to a meaningful decrease in specimen dry density. Recommended test method protocols were presented for AASHTO T134 and commentary was presented to provide state Departments of Transportation and other specifying agencies a few examples of how the new compaction delay protocols could be implemented.

Many online media platforms currently utilise algorithmically driven content moderation to prevent copyright infringement. This article explores content moderation’s effect on mashup music – a form of remix which relies primarily on the unauthorised combining of pre-existing, recognisable recordings. Drawing on interviews ( n = 30) and an online survey ( n = 92) with mashup producers, we show that content moderation affects producers’ creative decisions and distribution strategies, and has a strong negative effect on their overall motivation to create mashups. The objections that producers hold to this state of affairs often strongly resonate with current copyright exceptions. However, we argue that these exceptions, which form a legal ‘grey zone’, are currently unsatisfactorily accommodated for by platforms. Platforms’ political-economic power allows them, in effect, to ‘occupy’ and control this zone. Consequently, the practical efficacy of copyright law’s exceptions in this setting is significantly reduced.

Abstract Background Beginning in 2019, stepped-wedge designs (SWDs) were being used in the investigation of interventions to reduce opioid-related deaths in communities across the United States. However, these interventions are competing with external factors such as newly initiated public policies limiting opioid prescriptions, media awareness campaigns, and the COVID-19 pandemic. Furthermore, control communities may prematurely adopt components of the intervention as they become available. The presence of time-varying external factors that impact study outcomes is a well-known limitation of SWDs; common approaches to adjusting for them make use of a mixed effects modeling framework. However, these models have several shortcomings when external factors differentially impact intervention and control clusters. Methods We discuss limitations of commonly used mixed effects models in the context of proposed SWDs to investigate interventions intended to reduce opioid-related mortality, and propose extensions of these models to address these limitations. We conduct an extensive simulation study of anticipated data from SWD trials targeting the current opioid epidemic in order to examine the performance of these models in the presence of external factors. We consider confounding by time, premature adoption of intervention components, and time-varying effect modification— in which external factors differentially impact intervention and control clusters. Results In the presence of confounding by time, commonly used mixed effects models yield unbiased intervention effect estimates, but can have inflated Type 1 error and result in under coverage of confidence intervals. These models yield biased intervention effect estimates when premature intervention adoption or effect modification are present. In such scenarios, models incorporating fixed intervention-by-time interactions with an unstructured covariance for intervention-by-cluster-by-time random effects result in unbiased intervention effect estimates, reach nominal confidence interval coverage, and preserve Type 1 error. Conclusions Mixed effects models can adjust for different combinations of external factors through correct specification of fixed and random time effects. Since model choice has considerable impact on validity of results and study power, careful consideration must be given to how these external factors impact study endpoints and what estimands are most appropriate in the presence of such factors.

Abstract Background: Family planning is a key method for reducing population growth and improving maternal and child health by spacing births and preventing unwanted pregnancies. have an unmet need for family planning is defined as women believed to be sexually involved but are not using some form of contraception, either do not want to have more children (Limiting) or want to delay their next birth for at least two years, (Spacing).Methods: The data for this study arrived from the Ethiopia Demographic Health Surveys in 2005, 2011, and 2016 to investigate trends and Predictors of change of unmet need for family planning among reproductive age women in Ethiopia. A pooled weighted sample of 26,230 (7761 in 2005, 9136 in 2011 and 9,333 in 2016 Ethiopian demographic health surveys) reproductive-age women used for this study. For the overall trend (2005-2016) multivariate decomposition analysis for non-linear response outcome was calibrated to identify the factors contributed to the change of unmet need for family planning. The Logit based multivariate decomposition analysis utilizes the output from the logistic regression model to assign the observed change in in unmet need for family planning over time into two components. Stata version 16.0 was used to analysis the data.Result: among reproductive age women in Ethiopia the magnitude of unmet need for family planning decreased from 39.6% in 2005 to 23.6% in 2016. From the decomposition analysis change of unmet need for family planning was due to change in characteristics and coefficients. About nine in ten changes in unmet need for family planning was attributable to the difference in coefficients. Factors that associated with the change of unmet need for family planning over the last 11 years were educational status, birth order, and desired number of children.Conclusion: Remarkable change in unmet need for FP was observed between the period of 2005 and 2016. Both change in characteristics and coefficient were the contributing to observed change. Majority of the change in unmet need for FP was due to difference in coefficient over the study period. Mainly the change of unmet need for FP was due to change in women having birth order of five and above, having secondary education and women who desired number of children below five.

The Impact

The impact of automatic promotion practice on students dropping out of Uganda’s primary education was assessed using propensity score in difference in differences analysis technique. The analysis strategy was instrumental in addressing the selection bias problem, as well as biases arising from common trends over time, and permanent latent differences between the treated and control groups. Probit regression results indicate a negative effect on the probability of students dropping out, but only at P3. There seems to be no policy effect at P6. Decomposing the effect incidence along school location shows the policy as having had an effect only on P3 students studying in urban schools; otherwise, there is no effect among students at P3 rural, P6 rural or P6 Urban. In terms of the gender component, automatic promotion appears to have had an effect on P3 male and female students and no effect on either sex at P6.

The Danfa Comprehensive Rural Health and Family Planning Project was a joint effort of the Ghana Medical School, the Ministry of Health, UCLA, and USAID. A health education component was developed as an integral part of program inputs during the initial conceptual phase of the project. As a result non-equivalent experimental and control areas were designated permitting an assessment of program impact during a five-year period (1972–1977) for which baseline and follow-up study data were available. A new cadre of community-based workers (Health Education Assistants) was developed from existing health personnel in the country, and trained in health education and multipurpose health work. Although the HEAs were found to have difficulty in bringing about changes in health practices when other support services were not available, they did have measurable impact on villagers' adoption of family planning methods and a number of specific health practices.

The backflow vortexes at the suction connection in high-speed centrifugal pumps have negative effect on the flow field. Setting an orifice plate in front of the inducer is able to decrease the negative effect caused by backflow vortexes. The traditional plate is able to partially control the backflow vortexes, but a small part of the vortex is still in the inlet and the inducer. Four new types of orifice plates were created, and the control effects on backflow vortexes were analyzed. The ANSYS-CFX software was used to numerically simulate a high-speed centrifugal pump. The variations of streamline and velocity vectors at the suction connection were analyzed. Meanwhile, the effects of these plates on the impeller pressure and the internal flow field of the inducer were analyzed. Numerically, simulation and experimental data analysis methods were used to compare the head and efficiency of the high-speed pumps. The results show that the C-type orifice plate can improve the backflow vortex, reduce the low-pressure area, and improve the hydraulic performance of the high-speed pump.
