Generalizing from social media data: a formal theory approach

ABSTRACT

Researchers increasingly draw on social media data to answer big questions about social patterns and dynamics. However, as with any data source, social media data present both opportunities and significant challenges. One major critique of social media data is that the data are not generalizable outside of the platforms from which the data originate. Problems of generalizability stem from non-universal participation rates on various platforms, demographically biased samples, as well as limited access to data based on infrastructural constraints and/or user privacy practices. We suggest that instead of empirical generalizability, social media data are theoretically generalizable in the formal theory tradition. Through a case example in which we use YouTube comments to test and extend a key tenet of identity theory, we show how social media data can instantiate theoretical variables and thus generalize to theoretical propositions. Mediated through formal theory, social media data maintain the capacity to address broad social questions while upholding methodological integrity.     

Precedence tests for equality of two distributions based on early failures of ranked set samples

In this article, two different types of precedence tests, each with two different test statistics, based on ranked set samples for testing the equality of two distributions are discussed. The exact null distributions of proposed test statistics are derived, critical values are tabulated for both set size and number of cycles up to 8, and the exact power functions of these two types of precedence tests under the Lehmann alternative are derived. Then, the power values of these two test procedures and their competitors based on simple random samples and based on ranked set samples are compared under the Lehmann alternative exactly and also under a location-shift alternative by means of Monte Carlo simulations. Finally, the impact of imperfect ranking is discussed and some concluding remarks are presented.     

Tolerance of Homosexuality in 88 Countries: Education,Political Freedom,and Liberalism

Researchers have repeatedly found a positive correlation between education and tolerance. However, they may be victims of an unrepresentative sample containing only rich Western liberal democracies, where political agendas have a liberalizing effect on curricula. In this paper, we specify the relationship between education and liberal attitudes by analyzing data on educational attainment and tolerance of homosexuality (one dimension of liberalism) drawn from a heterogeneous sample of 88 countries over the period 1981–2014. We argue that nonliberal political agendas in some countries undermine the supposed universality of the positive relationship between educational attainment and tolerance of homosexuality. In relatively free countries, education is indeed associated with greater tolerance. However, in relatively unfree countries, education has no effect on tolerance and in some cases encourages intolerance. Specifically, our analysis demonstrates that education is associated with tolerance of homosexuality only when regimes energetically promote liberal‐democratic values. The larger theoretical point is that the agendas of political regimes shape civic values partly via education systems. Especially in an era when democracy is at risk in many countries, it is important to recognize that education is not always a benign force.     

The Chimera of Sustainable Labour–Management Partnership

The paper advances a threefold theoretical contribution using a system, society and dominance (SSD) effects framework to show how and why sustainable management–labour workplace partnerships are a chimera. First, managers (employers) find it increasingly difficult to keep workplace bargains with employees (unions) owing to increasingly neoliberal ‘system’ effects associated with capitalism as a globalized accumulation model. Second, workplace mutuality will be rare because of ‘societal’ level effects under voluntarism. Third, ‘dominance’ effects arising from the power of dominant economies and their multinational corporations can inhibit workplace mutuality. Drawing on empirical case study data from Ireland, the future prognosis of management–labour collaboration under neoliberal work regimes is discussed.     

Criticizing the Critic: Comments on Jahoda's (2012) Critique of Discursive Social Psychology

Jahoda (2012) criticizes discursive social psychology (DSP) on several different grounds; specifically, he argues that DSP has opaque methodological procedures, is of questionable scientific merit, involves over‐interpretation of its data, and implicitly claims its findings to be universal rather than contextually specific. We challenge these criticisms by arguing that observational studies of the kind typical within DSP research have a perfectly valid place within a scientific social psychology, that the interpretations made by DSP researchers should be seen in the context of a temporally extended research process in which they are subject to criticism and potential replication, and that Jahoda is himself guilty of over‐interpretation by inferring claims of universality when such an inference is not warranted by the data (i.e. the qualitative content of the sample of research papers considered by Jahoda).     

ADHD,depression, and substance abuse risk among beginning college students

Abstract

Objective: This study examined differences in substance use, depression, and academic functioning among ADHD and non-ADHD college students. Participants: Included 1,748 students (ages 18–25; women 68.4%; Caucasian 71.3%) with and without history of ADHD. Methods: We assessed the relationship of ADHD to substance use variables, controlling for depressive symptoms and examined relationships with GPA. Results: ADHD students were more likely to have engaged in frequent alcohol use, binge drinking, regular marijuana use and to have used other drugs in the last year. They reported higher depression symptoms than non-ADHD students, although substance abuse risk remained high even when controlling for depressive symptoms. ADHD students had lower overall GPA than those without ADHD. However, this difference was no longer significant when controlling for depression and marijuana use. Conclusions: College campuses should consider programing aimed at identifying ADHD students at risk for developing substance abuse problems and emotional difficulties.
