Patterns of Aggressive Behavior and Peer Victimization from Childhood to Early Adolescence: A Latent Class Analysis

The developmental period characterized by the transition from childhood and elementary school to early adolescence and middle school has been associated with increases in aggressive behavior and peer victimization. Few longitudinal studies, however, have examined the stability of aggression and victimization during this critical transition. This study uses latent class analysis (LCA) to examine patterns of aggressive behavior and victimization during the transition to middle school among urban, public school students (N = 458; Girls = 53%; Latino/a = 53%; M age at t1 = 10.2 years). Independent LCA models were conducted using self-reported data assessing subjects’ involvement in aggressive conduct and victimization during the spring semesters of grades four, five, and six. Elementary school students in the fourth grade initially belonged to one of four groups identified as aggressor, victim, aggressor-victim, and uninvolved latent classes. Contrary to prior research, membership in these classes changed significantly by the time students completed their first year of middle school with most youth participating in episodes of aggression and victimization during the transition. Six common paths that describe patterns of aggressive behavior and victimization from the last two years of elementary school to the first year of middle school were found. Findings are discussed in the context of social dominance theory and prior research that has found greater stability in aggression and victimization among early adolescents.     

The Influence of the Social Bond on Self-control at the Moment of Decision: Testing Hirschi’s Redefinition of Self-control

Hirschi (2004) redefined self-control as the tendency to consider the “full range” of potential costs relevant to a criminal act, suggesting that such costs vary in number and salience based on one’s level of self-control. He also suggested self-control, as expressed at the moment of decision, was influenced by the individual’s level of social bonding; those with fewer bonds would exhibit less self control by considering fewer costs and finding them less salient when making a decision. This study presents an initial attempt to examine Hirschi’s theoretical statement linking concepts from the two theories. Presented with a hypothetical drunk driving scenario, participants were asked to identify perceived costs and salience as a measure of self-control, as Hirschi (2004) suggested. Results support Hirschi’s assertion demonstrating that the social bond impacts offending likelihood through its relationship to self-control expressed within the decision. Future theoretical and empirical directions are outlined.     

Growing Stem Cells: The Impact of Federal Funding Policy on the U.S. Scientific Frontier

This paper articulates a citation‐based approach to science policy evaluation and employs that approach to investigate the impact of the United States’ 2001 policy regarding the federal funding of human embryonic stem cell (hESC) research. We evaluate the impact of the policy on the level of U.S. hESC research, the U.S. position at the knowledge frontier, and the strategic response of U.S. scientists. Consistent with recent research on the science of science and innovation policy, we employ a difference‐in‐differences approach using bibliometric data with the aim of analyzing the causal impact of the policy on cumulative research. Our estimates suggest that in the aftermath of the 2001 policy, U.S. production of hESC research lagged 35 to 40 percent behind anticipated levels. However, this relative decline was largely concentrated in the years 2001 to 2003 and ameliorated over time. The rebound in U.S. hESC research after 2003 was driven by contributions by researchers at elite U.S. institutions and U.S. researchers who collaborated with international partners. The results suggest that scientists respond strategically to research funding restrictions and that modest science policy shifts can have a significant influence on the within‐country composition of research and the pattern of global research collaboration.     

Tattoo frequency and types among homicides and other deaths, 2007-2008: a matched case-control study

An estimated 25% of the US population aged 18 to 50 years has a tattoo, which have been associated with markers of high-risk behaviors including alcohol and drug use, violence, carrying weapons, sexual activity, eating disorders, and suicide. This study compares tattoo prevalence and type in a homicide population to those of an age-, race-, and sex-matched control group of nonhomicide deaths. The data for this study were abstracted from autopsy records maintained by the Jefferson County Alabama Coroner/Medical Examiner's Office for the years 2007 and 2008. Odds ratios and 95% confidence intervals for the association between homicide and tattoo presence and characteristics were calculated using conditional logistic regression. There was no association between tattoo presence and death by homicide; however, among blacks, memorial tattoos were significantly more common among homicides compared with other types of deaths (odds ratio, 2.50; 95% confidence interval, 1.10-5.68). The results of the current study suggest that specific types of tattoos, but not all tattoos, may be risk factors for homicide. Other factors, such as race and lifestyle, along with tattoos may need to be considered.     

The effect of post-identification feedback, delay, and suspicion on accurate eyewitnesses

We examined whether post-identification feedback and suspicion affect accurate eyewitnesses. Participants viewed a video event and then made a lineup decision from a target-present photo lineup. Regardless of accuracy, the experimenter either, informed participants that they made a correct lineup decision or gave no information regarding their lineup decision. Immediately following the lineup decision or after a 1-week delay, a second experimenter gave some of the participants who received confirming feedback reason to be suspicious of the confirming feedback. Following immediately after the confirming feedback, accurate witnesses did not demonstrate certainty inflation. However, after a delay accurate witnesses did demonstrate certainty inflation typically associated with confirming feedback. The suspicion manipulation only affected participants' certainty when the confirming feedback created certainty inflation. The results lend support to the accessibility interpretation of the post-identification feedback effect and the erasure interpretation of the suspicion effect.     

John Vincent’s Reading at Gray’s Inn, 1668/9, on the Merchants’ Assurances Act 1601

In Lent Term 1668/9, John Vincent, a bencher of Gray’s Inn, gave a reading on the Merchants’ Assurances Act 1601 (43 Eliz. I, c.12). The notes of the law reporter, Joseph Keble, record this observance of the centuries-old tradition of readings, which was destined to expire within the next two decades. This paper situates Vincent’s reading within the changing tradition of readings in the seventeenth century. It highlights the role readings continued to play in disseminating sophisticated legal learning, particularly in relation to newer areas of practice such as marine insurance, which were largely uninformed by statute, common law precedent or reference works, and would have been difficult to master through book-study alone. It examines a selection of issues discussed during the reading, focussing on legal outcomes grounded in the ‘customs’, usages, practices and understandings of merchants, and illustrating how these were perceived as exceptional by comparison to the ordinary rules of the common law. The nature and jurisdiction of London’s court of assurances, reconstituted and empowered by the 1601 Act, are also discussed. More generally, this paper demonstrates the value of post-Restoration readings for historians of English law in the late seventeenth century.
