title: Missing Data Imputation With Baseline Information in Longitudinal Clinical Trials

description: In longitudinal clinical trials, missing data are inevitable despite every effort made to retain patients in the trial. Missing data cause difficulty in the estimation and interpretation of the treatment effect. When the primary objective is to assess the treatment effect in a realistic setting, it is necessary to take into consideration the impact of noncompliance to the treatment regimen. For estimation following the intention-to-treat principle, a return-to-baseline (RTB) approach may be used for continuous endpoints in some longitudinal clinical trials. The RTB approach is based on the assumption that the unobserved outcomes at the end of the trial represent a return to the baseline value, that is, any change observed while on treatment can be expected to wash out after patients drop out. This article describes a statistical approach for RTB analyses. The method for calculating the sample size using RTB approach is presented. A detailed illustration using this RTB approach based on publicly available longitudinal antidepressant clinical trial data is provided. Extensive simulations are presented to evaluate the performance of this RTB approach under various missing data mechanisms. Important limitations regarding the appropriateness of the underlying assumptions of RTB are discussed.

title: Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns

description: ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip intercropping systems under varied pedo-climatic conditions. Though component crops show yield reductions in row (additive and row-replacement series), mixed (seed blended crops) and strip intercropping systems, in general overall productivity per unit land area increases to a great extent. The significantly higher resource capturing with better utilization efficacy by intercrops in temporal and spatial dimensions helps explain their greater productivity. In addition, forage intercrops result in improved nutritional quality as legumes contain protein in double quantity than cereals. Cereal-legumes intercropping systems yield higher quantities of lush green forage with improved quality traits, which ultimately increase monetary benefits. Furthermore, legumes inclusion as an intercrop with cereals has the potential to serve as a nitrogen-saving strategy due to the biological nitrogen fixation (BNF) process. Moreover, cereal-legume intercropping systems are effective in reducing weed infestations and soil erosion by providing extended soil cover, as well as in increasing water use efficiency and improving soil fertility. However, despite a significant increase in overall productivity, component crops suffer yield losses in intercropping systems owing to competition for the finite divisible pool of growth resources. Thus, there is a dire need to optimize spatial and temporal arrangements in sorghum-legumes intercropping systems to achieve maximum productivity and economic returns.

title: Uniform Crime Reporting Program Data [United States]: Arrests by Age, Sex, and Race, Summarized Yearly, 2000
title: Version 1

description: These data provide information on the number of arrests reported to the Federal Bureau of Investigation's Uniform Crime Reporting (UCR) Program each year by police agencies in the United States. These arrest reports provide data on 43 offenses including violent crime, drug use, gambling, and larceny. The data received by ICPSR were structured as a hierarchical file containing, per reporting police agency: an agency header record, and 1 to 43 detail offense records containing the counts of arrests by age, sex, and race for a particular offense. ICPSR restructured the original data to logical record length format with the agency header record variables copied onto the detail records. Consequently, each record contains arrest counts for a particular agency-offense.

title: Version 1

description: This survey focuses on specific issues related to the United States' involvement in the Persian Gulf War, along with general topics such as the Bush presidency, whether the United States was heading in the right direction, foreign policy, Congress, and the economy. Respondents were asked about President Bush's handling of Iraq's invasion of Kuwait, if the United States did the right thing by starting military actions against Iraq rather than waiting to see if economic sanctions worked, if there was personal concern over a possible terrorist attack in the United States, whether the war was a mistake, and whether the war was likely to be worth the cost in human life and resources. Respondents also offered opinions regarding their pride or lack of pride in the United States' actions in the Persian Gulf, the expected length of the war and number of casualties, and how the war was going for the United States. In addition, the survey posed a series of questions dealing with media coverage of the war and the possible holding back of information by the military, the involvement of women in ground combat, personal effects of the war on respondents, Israel's response to Iraqi missile attacks, effects of the war on the United States' economy and on the Bush administration's ability to deal with domestic problems, support for Gorbachev vs. support for Lithuania's breaking away from the Soviet Union, Bush's first two years in office compared to Reagan's, Dan Quayle, and the probability of voting for Bush or the Democratic candidate in 1992. Background information on respondents includes political alignment, education, religion, age, race, sex, employment, perspectives on homemaking, family members serving in the Persian Gulf or elsewhere, choice for president in 1988, voter registration status, marital status, and state/region of residence.
