This paper contributes to the increasing research on how experts within financial institutions co-produce and organize financial markets, and in particular how equity analysts enact stock markets characterized by high volume and volatility. The 20 equity analysts studied give qualitatively different accounts of what, from an outsider's perspective, appear to be very similar work. The analysts understand investment objects, equity markets, and what constitutes good analytical work in qualitatively different ways. This heterogeneity, or multiplicity, could be one source of the, unexplained by orthodox financial theory, ‘excess’ volatility and ‘excess’ trading volume on financial markets. Therefore, the paper complements accounts within heterodox finance theory and sociology-based studies of financial market activities. 相似文献

Growing evidence suggests that child care instability is associated with child behavior problems, but existing studies confound different types of instability; use small, convenience samples; and/or control insufficiently for selection into child care arrangements. This study uses survey and calendar data from the Fragile Families and Child Well-Being Study to estimate the associations between three different types of child care instability—long-term instability, multiplicity, and the use of back-up arrangements—and children's internalizing, externalizing, and prosocial behaviors at age 3, controlling for a large number of child and family background characteristics. Long-term instability between birth and age 3, as measured in both the survey and calendar data, is associated with higher levels of externalizing behavior problems. Current multiplicity at age 3 (as measured by survey data) is associated with higher levels of both externalizing and internalizing behavior problems, but stable multiplicity over time (as measured using calendar data) is not. Finally, the use of back-up arrangements at age 3 is associated with higher levels of internalizing behaviors. We find no consistent differences in these results by the timing of instability, child gender, family income, or type of care. 相似文献

There are many well‐known or new methods to adjust statistical tests for multiplicity. This article provides an illustration helping lecturers or consultants to remember the differences of three important multiplicity adjustment methods and to explain them to non‐statisticians. 相似文献
