The Effect of Walkthrough Observations on Teacher Perspectives in Christian Schools
This study investigated the effects on teacher perceptions of frequent, brief classroom observations in Christian schools. Teachers (N=111) responded to 13 belief and value statements prior to and after the term during which administrators conducted weekly, brief, unannounced observations in their classes. Teachers reported significant positive change regarding (a) analyzing reasons for selecting methods to assess learning, (b) being encouraged after class observations, and (c) being encouraged after receiving feedback related to the observations

Enhancing Departments and Graduate Education in Geography
This paper describes the development, implementation, and preliminary outcomes of Enhancing Departments and Graduate Education (EDGE) in Geography, a multi-year project begun in 2005 to study the process of professional development in graduate geography in the U.S and sponsored by the National Science Foundation. As a research and action project responding to the needs of graduate geography programs, EDGE seeks to provide academic geographers with an empirical perspective of disciplinary as well as interdisciplinary and generic skills that M.A./M.S. and Ph.D. students develop as a result of graduate education. Related objectives are to understand how disciplinary skills are applied by geography graduates once they enter the professional workforce in both academic and non-academic professional settings, and to gauge the extent graduate programs are sufficiently preparing geography graduates for those careers.
We begin by summarizing the research goals and design of EDGE, highlighting the roles and contributions of geographers and educational researchers, and noting the interplay and synergy between disciplinary and interdisciplinary methodologies and practices. To date, research has focused on: 1) assessing contemporary workforce competencies in professional geography and 2) examining the role of department climate and culture on student experience and faculty development within masters and doctoral programs. Although the EDGE research efforts are still underway, we present some preliminary research findings and discuss the implications of those outcomes for professional development in geography and related social and environmental sciences. Also discussed is the complementary nature of discipline-based and interdisciplinary professional development efforts
AAPOR Report on Big Data
In recent years we have seen an increase in the amount of statistics in society describing different phenomena based on so called Big Data. The term Big Data is used for a variety of data as explained in the report, many of them characterized not just by their large volume, but also by their variety and velocity, the organic way in which they are created, and the new types of processes needed to analyze them and make inference from them. The change in the nature of the new types of data, their availability, the way in which they are collected, and disseminated are fundamental. The change constitutes a paradigm shift for survey research.There is a great potential in Big Data but there are some fundamental challenges that have to be resolved before its full potential can be realized. In this report we give examples of different types of Big Data and their potential for survey research. We also describe the Big Data process and discuss its main challenges
How Do Consumers Use Nutrition Labels on Food Products in the United States?
This study examined how consumers use food labels in the United States. Based on the results from the cluster analysis, eight nutrition label questions from the Health and Diet Survey fell into 2 categories of label usage: for shopping or for dietary decisions. Survey respondents reported equal or more consideration of nutrition-label information for dietary choices than for shopping decisions in 2008 compared with prior survey years. Female consumers, frequent label users, well-educated, consumers aged 50 to 59, or consumers with any health issues were significantly more likely to use food labels for all kinds of purposes than their corresponding counterparts
The Plight of Mixed Race Adolescents
Over the past 40 years, the fraction of mixed race black-white births has increased nearly nine-fold. There is very little empirical evidence on how these children fare relative to their single-race counterparts. This paper describes basic facts about the behaviors and outcomes of black-white mixed race individuals. As one might expect, on a host of background and achievement characteristics as well as adult outcomes, mixed race individuals fall in between whites and blacks. When it comes to engaging in risky and anti-social adolescent behavior, however, mixed race adolescents are stark outliers compared to both blacks and whites. We argue that these behavioral patterns are most consistent with a two-sector Roy model, in which mixed race adolescents – not having a predetermined peer group – engage in more risky behaviors to be accepted.mixed race; biracial; black white race; adolescent behavior
Mirroring to Build Trust in Digital Assistants
We describe experiments towards building a conversational digital assistant
that considers the preferred conversational style of the user. In particular,
these experiments are designed to measure whether users prefer and trust an
assistant whose conversational style matches their own. To this end we
conducted a user study where subjects interacted with a digital assistant that
responded in a way that either matched their conversational style, or did not.
Using self-reported personality attributes and subjects' feedback on the
interactions, we built models that can reliably predict a user's preferred
conversational style.Comment: Preprin
