Mass Democracy

Deliberative minipublics are popular tools to address the current crisis in democracy. However, it remains ambiguous to what degree these small-scale forums matter for mass democracy. In this study, we ask the question to what extent minipublics have “spillover effects” on lay citizens—that is, long-term effects on participating citizens and effects on non-participating citizens. We answer this question by means of a systematic review of the empirical research on minipublics’ spillover effects published before 2019. We identify 60 eligible studies published between 1999 and 2018 and provide a synthesis of the empirical results. We show that the evidence for most spillover effects remains tentative because the relevant body of empirical evidence is still small. Based on the review, we discuss the implications for democratic theory and outline several trajectories for future research.

Volume Effects

Purpose – The purpose of this paper is to test the long-term effects of price and volume with the help of Downward Sloping Demand Curve (DSDC) hypothesis, and also the short-term price and volume effects with the help of Price Pressure Hypothesis (PPH) for the index revisions on the S&P CNX Nifty 50 index. Design/methodology/approach – In order to report the long-term and short-term effects, the current study reviews two testable hypotheses, namely, DSDC hypothesis and PPH. The study has used the event study approach by including GARCH (1, 1) conditional variance in the market model. Findings – The results report that, the added stocks experienced a significant increase in price and volume on the effective date; whereas the deleted stocks experienced significant volume levels and insignificant price levels on the effective date. Accordingly, the study finds support in favor of PPH. Research limitations/implications – The study could not find evidence to support the most studied DSDC hypothesis. Practical implications – Index reorganization presumably affects the fund managers, domestic as well as international investors. As a result, studying the effect of index changes is a subject of attention to academicians and investors alike. Originality/value – The study contributes to the body of knowledge on index inclusion and exclusion effects by providing Indian evidence on long-term and short-term price and volume effects, and also documenting contrary results to the previous Indian and global research works.

Post Conflict

Mediation is widely used to settle armed conflict and interstate crises. However, the debate over the most appropriate and effective mediation strategy is still ongoing. In particular, manipulative mediation is controversial, with some research indicating that heavy-handed mediation may buy short-term peace at the expense of an instable long-term situation. This paper re-evaluates these claims. We discuss how existing theoretical arguments either do not imply long-term instability or implicitly make unrealistic assumptions to explain possible long-term problems of manipulative strategies. We re-examine published empirical evidence for problematic long-term effects of manipulative mediation in interstate crises. We demonstrate statistically that this evidence actually implies a different conclusion and instead supports our theoretical argument: manipulative mediation is associated with substantively greater stability compared to unmediated cases, although this effect weakens and becomes statistically insignificant after several years. Interestingly, non-manipulative mediation appears to be uncorrelated with post-crisis stability, based on our analysis.

The Future

This paper concerns predictions, reported in the press, which have been made by professional bodies and human rights organizations concerning the long-term effects on black youth of exposure to township conditions. It is contended that these predictions lend themselves to secondary victimization of black youth and it is postulated that they are not based on empirical evidence. Furthermore, they reflect several unquestioned assumptions concerning the nature of personality and childhood which permeate the very hegemonic order they intend to oppose. The implications of this for the future are explored. The difficulties of ever freeing oneself from operating within the categories inherent in a particular dominant ideology are highlighted by the author's own inevitable recourse to those very categories of which the validity is questioned in this paper.

Short And Long Term

It is generally known that during the 100 days of genocide against the Tutsi in Rwanda in 1994, sexual violence was committed on an unprecedented scale. Many women were first raped and then killed. With a certain degree of probability, the majority of Tutsi women who survived had been raped. Limited information is available regarding the experiences of these women. However, there is enough empirical evidence provided in human rights accounts and research reports substantiating that these women were exposed to unimaginable horror, which for the majority of them had a range of devastating short and long term effects. The programme of community-based sociotherapy was implemented in 2005 in the north of Rwanda in what was previously known as Byumba province, and subsequently in 2008 in Bugesera district in the south-east, one of the epicentres of the genocide.

Insight Into

This chapter presents empirical evidence regarding the (in)effectiveness of prisons for reducing crime. The authors begin with a brief discussion of the mechanisms through which incarceration affects crime, followed by a review of research that presents empirical evidence on the relationship between prisons and crime. This section separates empirical research on the total effect of prison on crime from empirical studies intended to isolate the deterrent or incapacitation effects of prison. Death penalty studies are also reviewed for insight into whether capital punishment has any short- or long-term effects on homicide rates. The chapter concludes with a brief discussion of the policy implications that follow from the empirical research on prison effects on crime.

Environmental Air Pollution

Housing markets are known to be affected by adverse environments (i.e., environmental air pollution incidents affect Indian urban residents). Urban atmosphere quality has changed extensively with PM2.5 and O3 becoming the primary atmosphere indicators of concern because of dense cities in recent years. There is a correlation between the air pollution of Amaravati with the housing market model. When estimating the housing market, the chapter makes use of the extended regression model together with several constant results in conformity with higher rule. However, there is an insignificant affinity including the concentration regarding SO2 and the concentration of O3 appears according to positively increase the housing values. This chapter therefore examines the influence of actual real estate investment over atmosphere characteristics through the use of a sample on 26 prefecture-level cities in India from 2010–2019 through countless econometric models.

Using Data

Rothstein (2017) successfully replicates Chetty, Friedman, and Rockoff's (2014a, b)—henceforth, CFR's—results using data from North Carolina, but raises concerns about CFR's methods. We show that Rothstein's methodological critiques are invalid by presenting simulations and supplementary empirical evidence which show that (i) his preferred imputation of missing data generates bias; (ii) his “placebo test” rejects valid research designs; and (iii) his method of controlling for covariates yields inconsistent estimates of teachers' long-term effects. Consistent with the conclusions of Bacher-Hicks, Kane, and Staiger (2016) using data from Los Angeles, we conclude that Rothstein's replication study ultimately reinforces CFR's methods and results.
