Second, we propose a probabilistic framework using Topic Models to discover prototypical impressions that are data driven, and that combine multiple facets of vloggers. First, we design a human annotation task to crowdsource impressions of vloggers that extends a tradition of studies of personality impressions with the addition of attractiveness and mood impressions. In this paper, we address the problems of (1) crowdsourcing the annotation of first impressions of video bloggers (vloggers) personal and social traits in conversational YouTube videos, and (2) mining the impressions with the goal of modeling the interplay of different vlogger facets. ![]() While multimedia and social computing research have used crowdsourcing techniques to annotate objects, actions, and scenes in social video sites like YouTube, little work has addressed the crowdsourcing of personal and social traits in online social video or social media content in general. ![]() Several explanations for our empirical results are discussed in view of the likelihood that the alcohol-income puzzle is a multicausal phenomenon. We also find a beer gain for residents of rural areas and a cocktail gain for residents of urban areas. When splitting the sample into age groups, the wine gain disappears for employees under the age of 35 and increases in size and significance for higher age groups. We are unable to detect endogeneity problems with the drinking variables, which speaks in favor of OLS regressions. Mincerian estimates reveal significant and positive relationships between wine drinkers and wages as well as between beverage-unspecific drinkers and wages. In our analysis, we disentangle the general wage effect of drinking into diverse effects for different types of drinkers. More importantly, we shed light on the alcohol-income puzzle by analyzing, for the first time, the association between beverage-specific drinking behavior and wages. Using individual-based microdata from the GSOEP for 2006, we confirm that this relationship exists for Germany as well. Positive health effects as well as networking mechanisms serve as explanations for the alcohol-income puzzle. The positive association between moderate alcohol consumption and wages is well documented in the economic literature. ![]() For Black students there were significant within group differences in intercultural dating based on skin tone. Results confirm that White students continue to be the group most likely to engage in intragroup dating relationships, Latino/a students were the most likely to date interculturally, and that Black men were significantly more likely to date interculturally than Black women. Hierarchical linear modeling analyses were conducted on a 4-year longitudinal sample of 2804 undergraduate students from 24 colleges and universities. While most previous research has examined general racial/ethnic and gender differences in intercultural college dating experiences, this study analyzes precollege and college-going friendship diversity and skin tone as factors accounting for romantic distance between racial/ethnic groups among a recent cohort of college students. Studying dating experiences across racial and ethnic lines has been used to determine the existence of a post-racial America. The increased representation of minority students on the campuses of predominantly White universities in the United States presents increased opportunities for intercultural contact.
