Social Networks and Protest Participation: Evidence from 130 Million Twitter Users

Pinning down the role of social ties in the decision to protest has been notoriously elusive, largely due to data limitations. Social media and their global use by protesters offer an unprecedented opportunity to observe real‐time social ties and online behavior, though often without an attendant measure of real‐world behavior. We collect data on Twitter activity during the 2015 Charlie Hebdo protest in Paris, which, unusually, record real‐world protest attendance and network structure measured beyond egocentric networks. We devise a test of social theories of protest that hold that participation depends on exposure to others' intentions and network position determines exposure. Our findings are strongly consistent with these theories, showing that protesters are significantly more connected to one another via direct, indirect, triadic, and reciprocated ties than comparable nonprotesters. These results offer the first large‐scale empirical support for the claim that social network structure has consequences for protest participation.     

Sustaining the State: Legal Consciousness and the Construction of Legality in Competing Abortion Activists' Narratives

This article investigates how activists involved in both sides of the street politics of abortion simultaneously create, are constrained by, and use law when recounting a period of conflict that resulted in litigation. The activists‐turned‐litigants' construction of legality is explored by identifying and analyzing patterns of inclusion, absence, amendment, and type of law (i.e., state or extrastate) in and across the stories they tell. It is found that even though there are multiple reasons to expect all of these activists to resist or amend the state's conception of law, their narratives ultimately reproduce state law's legitimacy and power. The activists' stories also illustrate that legal consciousness is contextually and experientially based and is therefore subject to change. This finding has implications for legal mobilization as well as for the nature of legal consciousness.     

Who Benefits from KIPP?

The nation's largest charter management organization is the Knowledge is Power Program (KIPP). KIPP schools are emblematic of the No Excuses approach to public education, a highly standardized and widely replicated charter model that features a long school day, an extended school year, selective teacher hiring, strict behavior norms, and emphasizes traditional reading and math skills. No Excuses charter schools are sometimes said to target relatively motivated high achievers at the expense of students who are more difficult to teach, including limited English proficiency (LEP) and special education (SPED) students, as well as students with low baseline achievement levels. We use applicant lotteries to evaluate the impact of KIPP Academy Lynn, a KIPP school in Lynn, Massachusetts that typifies the KIPP approach. Our analysis focuses on special needs students that may be underserved. The results show average achievement gains of 0.36 standard deviations in math and 0.12 standard deviations in reading for each year spent at KIPP Lynn, with the largest gains coming from the LEP, SPED, and low‐achievement groups. Average reading gains are driven almost entirely by SPED and LEP students, whose reading scores rise by roughly 0.35 standard deviations for each year spent at KIPP Lynn.     

Greening Constitutions with Environmental Rights: Testing the Isomorphism Thesis

Why do some countries have constitutional environmental rights while others do not? In this paper, I conduct statistical analyses to respond to this inquiry. Through studying the impact of intraregional constitutional design, I aim to understand why states adopt environmental rights. I argue that regional isomorphism—i.e., the tendency among states within a region to converge on certain policies—may explain the trend toward constitutionalization of environmental rights. In this paper I (1) define and provide historical background on environmental rights, (2) describe theories which support regional isomorphism as a means of explaining the adoption of constitutional environmental rights, and (3) conduct statistical tests to determine the validity of the regional isomorphism thesis. I find that the enactment of constitutional environmental rights within a region does not increase the likelihood that another state within the same region will include environmental rights within its constitution.     

Gender differences in the effects of prison on recidivism

Purpose

This study examines gender differences in the effectiveness of prison in reducing recidivism.

Methods

Using data on released male and female prisoners, we apply a propensity score matching methodology to compare the effects of prison on recidivism versus three counterfactual conditions—jail, intensive probation, and probation.

Results

The analyses indicated that a prison term, as compared to placement on intensive probation or traditional probation, is associated with a greater likelihood of property and drug recidivism. There was little evidence that recidivism was greater when compared to jail, that prison increased the likelihood of violent or other recidivism, or that the criminogenic effect of prison is appreciably greater for females or males.

Conclusions

The findings do not support arguments that prison is an effective alternative to non-incarcerative punishments or that it exerts a differential effect on females or males. Further research is needed on what features of the prison experience contribute to the observed effects.     

Examining the relationship between childhood animal cruelty motives and recurrent adult violent crimes toward humans

Few researchers have studied the predictive ability of childhood animal cruelty motives as they are associated with later recurrent violence toward humans. Based on a sample of 180 inmates at one medium- and one maximum-security prison in a Southern state, the present study examines the relationship among several retrospectively identified motives (fun, out of anger, hate for the animal, and imitation) for childhood animal cruelty and the later commission of violent crimes (murder, rape, assault, and robbery) against humans. Almost two thirds of the inmates reported engaging in childhood animal cruelty for fun, whereas almost one fourth reported being motivated either out of anger or imitation. Only one fifth of the respondents reported they had committed acts of animal cruelty because they hated the animal. Regression analyses revealed that recurrent animal cruelty was the only statistically significant variable in the model. Respondents who had committed recurrent childhood animal cruelty were more likely to have had committed recurrent adult violence toward humans. None of the motives for committing childhood animal cruelty had any effect on later violence against humans.     

An Overview of the Rorschach Performance Assessment System (R-PAS)

We provide an overview of the Rorschach Performance Assessment System (R-PAS; Meyer, Viglione, Mihura, Erard, & Erdberg, 2011). After providing a general introduction to Rorschach-based assessment, the rationale and features of R-PAS are outlined. As part of this discussion, some of the ways in which R-PAS differs from the Comprehensive System (CS) (Exner, 2003) are delineated.
