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.

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.

This concluding chapter uses the empirical evidence presented in previous chapters to reflect on the influence of foreign policy and ethnic politics on countries’ approaches to refugees. It considers the implications of these findings for a reconceptualization of the relationship between sovereignty and rights. The chapter also addresses the consequences of selective sovereignty for the international refugee regime. In so doing, it suggests some policy implications, such as attempting to identify when and where the international community can fruitfully exert pressure on states to welcome refugees. Selective sovereignty shapes the experiences of growing numbers of refugees around the world and, as a result, has consequences for long-term processes related to conflict, peacebuilding, and post-conflict reconstruction. Recent events underscore the importance of understanding why states sometimes assert their sovereignty and at other times uphold refugee rights.

Microexpressions do exist, and they are regarded as valid cues to deception by many researchers, furthermore, there is a lot of empirical evidence which substantiates this claim. However, some researchers don’t think the microexpression can be a way to catch a liar. The author elucidates the theories predicting that looking for microexpressions can be a way to catch a liar, and notes that some data can support for the utilization of microexpressions as a good way to detect deception. In addition, the author thinks that the mixed results in the area of investigating microexpressions and deception detection may be moderated by the stake. More empirical studies which employ high-stake lies to explore the relationship between microexpressions and deception detection are needed.

Many mathematics educators believe a goal of instruction is for students to obtain conviction and certainty in mathematical statements using the same types of evidence that mathematicians do. However, few empirical studies have examined how mathematicians use proofs to obtain conviction and certainty. We report on a study in which 16 advanced mathematics doctoral students were given a task-based interview in which they were presented with various sources of evidence in support of a specific mathematical claim and were asked how convinced they were that the claim was true after reviewing this evidence. In particular, we explore why our participants retained doubts about our claim after reading its proof and how they used empirical evidence to reduce those doubts.

Few data are available in the literature describing the long-term effects of envenoming in the perinatal period. In this study, the relationship between envenoming of lactating rats and possible behavioral changes in the mother and in her offspring were investigated. Lactating Wistar rats received a single dose of T. serrulatus crude venom on postnatal days 2 (V2), 10 (V10) or 16 (V16), and had their maternal behavior evaluated. The seizure threshold was evaluated in adulthood offspring. A decrease in maternal care during envenoming was observed in V2 and V10 groups. The retrieval behavior was absent in the V2 group, and a lower seizure threshold in the adult offspring of all groups was observed. During envenoming, mothers stayed away from their offspring for a relatively long time. Maternal deprivation during the early postnatal period is one of the most potent stressors for pups and could be responsible, at least in part, for the decrease in the convulsive threshold of the offspring since stress is pointed to as a risk factor for epileptogenesis. Furthermore, the scorpionic accident generates an intense immune response, and inflammation in neonates increases the susceptibility to seizures in adulthood. Therefore, maternal envenoming during lactation can have adverse effects on offspring in adulthood.

The focus of this study is on the soil physicochemical, biological, and microbiological processes altered by biochar application to heavy metal (HM) contaminated soils. The aim is to highlight agronomical and environmental issues by which the restorative capacity of biochar might be developed. Literature shows biochar can induce soil remediation, however, it is unclear how soil processes are linked mechanistically to biochar production and if these processes can be manipulated to enhance soil remediation. The literature often fails to contribute to an improved understanding of the mechanisms by which biochar alters soil function. It is clear that factors such as biochar feedstock, pyrolysis conditions, application rate, and soil type are determinants in biochar soil functionality. These factors are developed to enhance our insight into production routes and the benefits of biochar in HM soil remediation. Despite a large number of studies of biochar in soils, there is little understanding of long-term effects, this is particularly true with respect to the use and need for reapplication in soil remediation.

Direct Foreign Investment (FDI) has been considered as one of the important strategies in long-term economic development. FDI is seen not only as a capital transfer but also has an important effect on increasing the host economy. FDI then became popular in many countries, so it was interesting to analyze the effects produced, both positive and negative. This research focuses on countries in the Association of Southeast Asian Nations (ASEAN) with the aim of conducting empirical studies on opportunities for employment creation by FDI. However, due to limited data in several countries, this study only involved Indonesia, Singapore, Malaysia and Thailand. The type of data used in this study is annual data covering from 1980-2017. Using estimation Vector Error Correction Model (VECM) allows to see short-term and long-term effects. The test results prove that the influence between variables is more visible in the long run

Adverse childhood experiences (ACEs) have been identified as a key risk factor for a range of negative life outcomes, including delinquency. Much less is known about how exposure to negative experiences relates to continued offending among juvenile offenders. In this study, we examine the effect of ACEs on recidivism in a large sample of previously referred youth from the State of Florida who were followed for 1 year after participation in community-based treatment. Results from a series of Cox hazard models suggest that ACEs increase the risk of subsequent arrest, with a higher prevalence of ACEs leading to a shorter time to recidivism. The relationship between ACEs and recidivism held quite well in demographic-specific analyses. Implications for empirical research on the long-term effects of traumatic childhood events and juvenile justice policy are discussed.

This chapter focuses on Georges Gilles de la Tourette’s poetical pursuits. A man of many talents, these poems provide insight into yet another facet of Gilles de la Tourette’s personality. As well, they may provide some clue to his mental state as he suffered from the long-term effects of syphilis. It is difficult to know whether these poems should be taken as initial signs of Gilles de la Tourette’s disease or whether they are a simple manifestation of his imagination and the pleasure he took in writing. His poetry can be found at the family archive in Loundun.
