Economic Circumstances and Family Outcomes: A Review of the 1990s

Abstract: This review documents the economic context within which American families lived in the 1990s. Despite nearly full employment and growing income and wealth for many Americans, problem areas included persistent racial gaps in economic well-being, growing inequality, and declining wages for young men. Women showed stronger income growth than men in the decade, and 2-earner households became increasingly associated with advantage. We review the consequences of these trends and of economic well-being generally on 4 dimensions of family outcomes: family formation, divorce, marital quality, and child well-being. Despite hypotheses suggesting that women's earnings might have different effects on family outcomes than men's earnings, generally the review supports the expectation that both men's and women's economic advantage is associated with more marriage, less divorce, more marital happiness, and greater child well-being. Important issues regarding measurement, reciprocal relations between family structure and economic well-being, and race and gender effects remain unresolved.

Best practice recommendations for data screening.

Abstract: Summary Survey respondents differ in their levels of attention and effort when responding to items. There are a number of methods researchers may use to identify respondents who fail to exert sufficient effort in order to increase the rigor of analysis and enhance the trustworthiness of study results. Screening techniques are organized into three general categories, which differ in impact on survey design and potential respondent awareness. Assumptions and considerations regarding appropriate use of screening techniques are discussed along with descriptions of each technique. The utility of each screening technique is a function of survey design and administration. Each technique has the potential to identify different types of insufficient effort. An example dataset is provided to illustrate these differences and familiarize readers with the computation and implementation of the screening techniques. Researchers are encouraged to consider data screening when designing a survey, select screening techniques on the basis of theoretical considerations (or empirical considerations when pilot testing is an option), and report the results of an analysis both before and after employing data screening techniques.

Evaluation of a Filter Bag System for NDF, ADF, and IVDMD Forage Analysis

Abstract: A new method of determining in vitro dry matter digestibility (IVDMD) was recently developed in which the digestion is conducted with the forage samples in filter bags. Our objective was to compare the filter bag and conventional IVDMD analysis methods using smooth bromegrass (Bromus inermis Leyss.), switchgrass (Panicum virgatum L), and forage sorghum [Sorghum bicolor (L.) Moench] samples. In addition, the filter bag analysis systems for determining non-sequential neutral and acid detergent fiber (NDF and ADF), respectively, were compared with the non-sequential conventional analysis systems. In the filter bag systems, the forage samples are sealed in filter bags and the analyses are conducted on a batch basis rather than on an individual basis as in the conventional IVDMD and fiber analysis procedures. The filter bag analysis methods produced results similar to the conventional methods and ranked the forage samples in the same relative order.
