Race and the beauty premium: Mechanical Turk workers’ evaluations of Twitter accounts

ABSTRACT

Race, gender, and physical attractiveness strongly affect perceptions of trustworthiness and subsequent face-to-face interactions. This study examines how social media users’ perceived gender, race, and physical attractiveness can impact their standing online. We test these broad hypotheses by having Amazon Mechanical Turk (MTurk) workers evaluate a sample of 816 Twitter accounts. Our results show a ‘beauty premium,’ where MTurk workers say they are more likely to follow Twitter accounts with attractive pro?le photos, and attractive photos are positively associated with evaluations of trust. However, very attractive Black male and female Twitter accounts are associated with lower evaluations of trust compared to their White counterparts. These findings suggest that social media users’ social characteristics, perceived from their username or profile image, can replicate offline inequality online.     

The correlated random walk in continuous time with barriers

In this paper correlation has been introduced between two successive transitions in the model investigated by Moyal and Heathcote (1959). The transition rate has been taken to be constant and for simplicity of mathematical expressions the time scale has been so chosen that this rate is unity. For the unrestricted walk we find that the mean position of the particle at time t is that position for which the probability of the particle arriving at some earlier instant from the left is 1/2. With both the barriers either absorbing or reflecting, we have obtained the Laplace Transform of the distributions, but because of the complicated nature of the mathematical expressions involved we are able to find only the asymptotic distributions. For the reflecting barrier case, we find that the process tends to a stationary distribution and that the expected position is eventually the middle point between the barriers.     

Bayesian inference of the inverse Weibull mixture distribution using type-I censoring

A large number of models have been derived from the two-parameter Weibull distribution including the inverse Weibull (IW) model which is found suitable for modeling the complex failure data set. In this paper, we present the Bayesian inference for the mixture of two IW models. For this purpose, the Bayes estimates of the parameters of the mixture model along with their posterior risks using informative as well as the non-informative prior are obtained. These estimates have been attained considering two cases: (a) when the shape parameter is known and (b) when all parameters are unknown. For the former case, Bayes estimates are obtained under three loss functions while for the latter case only the squared error loss function is used. Simulation study is carried out in order to explore numerical aspects of the proposed Bayes estimators. A real-life data set is also presented for both cases, and parameters obtained under case when shape parameter is known are tested through testing of hypothesis procedure.     

Managing ambiguity: between markets and managerialism - a case study of 'middle' managers in further education

Advocates of devolved and market oriented Education reform, point to the benefits from self determination which enhance both teacher and managerial autonomy. Critics refer, on the other hand, to the ways in which running education institutions on business and accounting principles have introduced a new managerialism (Clarke et al, 1994; Pollitt, 1990; Clarke and Newman, 1997), which has driven a wedge between lecturers and senior manager interests. In Further Education, according to Elliott (1996a), this finds expression in conflict between lecturers in defence of professional and pedagogic values, and senior managers promoting the managerial bottom line (Randle and Brady, 1994). The danger in polarising such interests in this way is that it presents a plausible, if not oversimplified, analysis of organisational behaviour as market forces permeate FE. If this paper concurs with many critics on the effects of the new managerialism, it departs company from a prevailing determinism which assumes an over controlled view of the FE workplace (Seddon and Brown, 1997). Despite evidence of widespread casualisation and deprofessionalisation in FE, this paper examines changing managerial cultures in the FE workplace, in this case among academic 'middle' managers, which suggests that managerialism is not as complete or uncontested as is often portrayed. The paper draws on an ESRC research project conducted by the authors (ESRC no. R000236713), looking at Changing Teaching and Managerial Cultures in FE, at a time when the sector is emerging from a series of funding crises associated with redundancies, industrial action, mismanagement and low morale at college level.     

Ethnic‐racial Socialization,Perceived Neighborhood Quality,and Psychosocial Adjustment among African American and Caribbean Black Adolescents

Ethnic–racial socialization is employed by ethnic minority parents to support their children’s psychosocial adjustment. These socialization messages may be associated differently with psychosocial adjustment for Black youth according to ethnicity and qualities of the neighborhood context. This research examined whether associations between ethnic–racial socialization messages and psychosocial adjustment vary by ethnicity and perceived neighborhood quality in a nationally representative sample of Black adolescents who participated in the National Survey of American Life Adolescent supplement study. The effects of promotion of mistrust messages varied by ethnicity, and the effects of egalitarianism messages varied depending on perceived neighborhood quality. These findings help clarify prior research which has yielded equivocal results for the effects of these messages for Black youth’s psychosocial adjustment.     

Why are fewer married women joining the work force in rural India? A decomposition analysis over two decades

In contrast with global trends, India has witnessed a secular decline in women’s employment rates over the past few decades. We investigate this decline in rural areas, where the majority of Indian women reside. Using parametric and semi-parametric decomposition techniques, we show that changes in individual and household attributes fully account for the fall in women’s labor force participation in 1987–1999 and account for more than half of the decline in 1999–2011. Our findings underscore increasing education levels among rural married women and the men in their households as the most prominent attributes contributing to this decline. We provide suggestive evidence that changes in more educated women’s relative returns to home production compared with market production may have adversely affected female labor force participation in rural India.     

Moving Toward a Holistic Conceptual Framework for Understanding Healthy Aging Among Gay Men

In the last four decades, we have witnessed vast and important transitions in the social, economic, political, and health contexts of the lived experiences of gay men in the United States. This dynamic period, as evidenced most prominently by the transition of the gay rights movement to a civil rights movement, has shifted the exploration of gay men’s health from one focusing primarily on HIV/AIDS into a mainstream consideration of the overall health and wellbeing of gay men. Against this backdrop, aging gay men in the United States constitute a growing population, for whom further investigations of health states and health-related disparities are warranted. In order to advance our understanding of the health and wellbeing of aging gay men, we outline here a multilevel, ecosocial conceptual framework that integrates salient environmental, social, psychosocial, and sociodeomgraphic factors into sets of macro-, meso-, and micro-level constructs that can be applied to comprehensively study health states and health care utilization in older gay men.
