Statistical considerations for crowdsourced perceptual ratings of human speech productions

Crowdsourcing has become a major tool for scholarly research since its introduction to the academic sphere in 2008. However, unlike in traditional laboratory settings, it is nearly impossible to control the conditions under which workers on crowdsourcing platforms complete tasks. In the study of communication disorders, crowdsourcing has provided a novel solution to the collection of perceptual ratings of human speech production. Such ratings allow researchers to gauge whether a treatment yields meaningful change in how human listeners' perceive disordered speech. This paper will explore some statistical considerations of crowdsourced data with specific focus on collecting perceptual ratings of human speech productions. Random effects models are applied to crowdsourced perceptual ratings collected in both a continuous and binary fashion. A simulation study is conducted to test the reliability of the proposed models under differing numbers of workers and tasks. Finally, this methodology is applied to a data set from the study of communication disorders.     

Regression models for analyzing clustered binary and continuous outcomes under an assumption of exchangeability

Scientific experiments commonly result in clustered discrete and continuous data. Existing methods for analyzing such data include the use of quasi-likelihood procedures and generalized estimating equations to estimate marginal mean response parameters. In applications to areas such as developmental toxicity studies, where discrete and continuous measurements are recorded on each fetus, or clinical ophthalmologic trials, where different types of observations are made on each eye, the assumption that data within cluster are exchangeable is often very reasonable. We use this assumption to formulate fully parametric regression models for clusters of bivariate data with binary and continuous components. The regression models proposed have marginal interpretations and reproducible model structures. Tractable expressions for likelihood equations are derived and iterative schemes are given for computing efficient estimates (MLEs) of the marginal mean, correlations, variances and higher moments. We demonstrate the use the ‘exchangeable’ procedure with an application to a developmental toxicity study involving fetal weight and malformation data.     

Conducting and utilizing evaluation for multiple accountabilities: A study of nonprofit evaluation capacities

This article combines the evaluation capacity building and nonprofit accountability literature to examine how nonprofits use evaluation data to address stakeholder expectations. Our study investigates how staff competency, technological resources, learning climate, and strategic planning influence a nonprofit's ability to demonstrate upward, lateral, and downward accountabilities. Results indicate different combinations of evaluation capacities matter more for particular stakeholder groups. We argue a more integrative nonprofit accountability requires that managers and staff know how to utilize evaluation results for internal and external audiences. Nuances between specific evaluative capacities and their influences on multiple accountabilities suggest several implications for practice.     

Success According to Professionals in the Fashion Industry

The purpose of this study was to examine career success perceived by professionals in the fashion industry. Two sets of open‐ ended interviews were conducted with 33 fashion industry professionals. The interviews were analyzed for success themes using a grounded approach methodology. External definitions of success mentioned were salary, promotions, sales, being seen as an expert, and having influence. Internal rewards included being innovative, maintaining integrity, and work satisfaction. Attributes identified as important for career success were motivation, flexibility, a positive attitude, networking ability, enjoying work, a mentor, self‐promotion, multitasking, following instinct, dressing well, and doing research.     

Visually Assessing the First Lady in a Digital Age: A Study of Michelle Obama as Portrayed by Journalists and the White House

In a digital age in which the First Lady’s image is captured and disseminated by many different outlets, this article proposes the development of a coding instrument using Goffman’s (1979) gender displays as a new method for exploring the visual frames of the First Lady. Given the manner in which photographs are disseminated via the Internet by both official and journalistic sources, this new coding instrument takes into consideration the different vantage points that these image capturers have. Until recently, visual gender display frames of the First Lady from differing outlets have not been easily studied separately, given the fact that images disseminated by the White House had to go through the journalistic gate prior to dispersion. Ultimately, the study of photos of the First Lady as she appears in the “media” was mixed and confounded journalistic and official framing. The Internet has changed all of this and opens opportunities to study these framing sources separately. As a test of a new coding instrument to study these different framing sources, this article assesses Michelle Obama in her gender portrayal from two different framing sources: journalists and the White House. This visual content analysis demonstrates and supports the use of a new context-independent coding instrument, borrowing from Goffman’s gender displays as a method for visually studying the First Lady.     

Rejection,Humiliation, and Parole: A Study of Parolees' Perspectives

Research on status rejection has developed considerably over the past two decades and is applied in a number of different settings to better understand criminal and deviant behavior. Our research contributes to that body of work by examining the ways in which status rejection may create a potentially humiliating dynamic for individuals on parole. Specifically, we use in‐depth interviews with parolees to illustrate how the parolee identity can promote the experience of status rejection and simultaneously foster conditions for humiliation—an emotional state that may impede one's ability to both (re) construct a conventional identity and reintegrate back into one's community.     

Psychiatric emergencies: the check effect revisited.

Federal income support to persons with alcohol and drug related disabilities was ended in 1997. The argument for ending the programs was that recipients were using their benefits to purchase drugs and alcohol. This supposedly led to the "check effect," an increase in psychiatric emergencies in American communities in the days following the receipt of disability benefits. We test two hypotheses implied by this argument. The first is that psychiatric emergencies are elevated in the fourth through eighth day of the month. The second is that the excess of emergencies in these days was significantly reduced when benefits were ended. The tests are based on 35,500 psychiatric emergencies in San Francisco, California occurring over 1,551 days. Results support the first hypothesis but not the second. The implications are that there is a general check effect and that it was not reduced by ending benefits to persons with drug and alcohol related disabilities.     

Observations of Adolescent Peer Group Interactions as a Function of Within‐ and Between‐Group Centrality Status

Observations of adolescent (n = 258; M age = 15.45) peer group triads (n = 86) were analyzed to identify conversation and interaction styles as a function of within‐group and between‐group centrality status. Group members' discussions about hypothetical dilemmas were coded for agreements, disagreements, commands, and opinions. Interactions during a hypothetical decision were rated for openness, dominance, aggression, and prosocial behavior. Hierarchical linear modeling revealed that higher within‐group status predicted more disagreements, commands, and less openness than lower within‐group status. Interactions showed that prosocial and aggressive behavior varied as a function of individual status in low‐status but not high‐status groups. Boys, but not girls, engaged in more openness in higher status groups. Results provide insights into peer socialization.
