Shoe print examinations: effects of expectation, complexity and experience

Even though trace evidence is becoming more and more important in legal cases, only little is known about the influence of task and context factors on comparative judgments. In the present study we investigated how expectations and complexity affect shoe print examinations and to what extent differences exist between beginners and experienced examiners. Twelve examiners assessed similarity between a shoe print and a shoe for eight different cases. For half the cases expectation was induced by providing additional incriminating evidence. A complex case meant that the print was relatively noisy, for example because the perpetrator rotated his foot. A simple case meant that the print was clear. The results showed that there was no effect of expectation and no effect of experience. Only complexity affected the examiners' assessments: when the background was noisy, the acquired features received a lower evidential value than when the background was clear. Apparently, examiners compensated for the quality of the print and were more cautious in drawing conclusions when prints were less clear. Even though the results allow for some optimism with regard to the influence of expectations on shoe print examinations, it has to be taken into account that the Dutch procedure is supported by a formal guideline, which may (partly) explain the present findings.     

The Role of Peer Contacts in the Relationship Between Parental Knowledge and Adolescents' Externalizing Behaviors: A Latent Growth Curve Modeling Approach

The purpose of the present study was to examine the direct and indirect effects (through peer contacts) of parental knowledge on adolescents’ delinquent and aggressive problem behavior, using latent growth curve modeling. A sample of 457 13- to 14-year old adolescents at first measurement wave (M=13.27; SD=0.45 years) filled out questionnaires about their parents, peers, and problem behavior three times with 1-year intervals in between. Regarding initial levels of behavior, both direct and indirect effects of parental knowledge were found on aggressive as well as on delinquent behavior. When the rate of change in behaviors was considered, only direct effects were found for both types of problem behavior, whereas indirect effects were absent. Gender differences were also found, with stronger effects of parenting on both aggressive and delinquent problem behavior for boys and stronger effects of peer contacts on aggressive behavior for girls. The present study shows that different behaviors of the externalizing spectrum have different trajectories and diverse relations with parenting and should not be treated as identical.

Dimensions of Chinese foreign conflict and cooperation: A research note

Key mediation attributes, such as mediating actors, the strategy they choose, and previous mediation experiences, are widely thought to influence the nature of a conflict management outcome. But how and when these features shape outcomes is not a straightforward matter, and a standard analysis of these factors does not lead to their widely anticipated results. Why? We develop a new analytical framework that argues that a dispute's intensity alters the conflict management processes. Furthermore, in order to observe this variation, we also need to expand the traditional, dichotomous notion of conflict management outcomes (success or failure) to include a fuller range of observed results. Using the most recent International Conflict Management data set and our new analytical framework, we analyze the effect on conflict management outcome of mediator (a) identity, (b) strategy and (c) history. We find that directive strategies and international mediators are effective in resolving high intensity conflicts, procedural strategies and regional mediators are effective in resolving low intensity conflicts, and that mediation history always affects resolution. Our results have implications for both the study and practice of international dispute mediation.     

Social Network Position of Gang Members in Schools: Implications for Recruitment and Gang Prevention

Schools are venues in which gang and non-gang involved youth converge. It is therefore a likely venue for gang recruitment. The extent to which this occurs depends upon the ability of gang members to connect with non-gang members. In this study, we compare the social network positions of high social status gang members who are well integrated into school networks with low status members who are not. Using network data from the Add Health study (n = 1,822), we find that not only are high status gang members strongly embedded within school networks, but that this status is driven by their ability to connect with non-gang members rather than other gang members (indicated by the high number of friendship nominations they receive from non-gang members). These gang members are potentially in optimal positions to influence others to join gangs. The implications of these results for school-based gang prevention programs are discussed.     

Trauma Symptoms of Former Intimate Stalking Victims

Abstract

One-hundred-eighty-seven female victims stalked by former intimate partners were interviewed about their victimization experiences. To identify psychological symptoms experienced by the victims, Briere and Runtz's (1989) Trauma Symptom Checklist (TSC-33) was utilized in the interview. Individual items were combined to form five distinct scales as developed and validated by Briere and Runtz (1989). Findings reveal that the highest mean scores for the sample were on the items included in the Sleep Disturbance scale. In addition, overall TSC-33 scores and the Dissociation, Anxiety, Depression, and Post-Sexual Assault Trauma-hypothesized (PSAT-h) scale scores varied by whether or not victims had experienced violence during their former relationship with the stalker and by whether or not violence occurred during the stalking. The absence or presence of verbal threats of violence during the stalking, however, did not have an independent effect on most emotional symptoms when controlling for violence during stalking.     

Examining the effectiveness of a UK community-based sexual offender treatment programme for child abusers

Abstract

An analysis of psychometric data from a sample of 341 UK child abusers who had completed a probation-based sex offender treatment programme was carried out in order to assess the effectiveness of therapeutic treatment. A cluster analysis was also undertaken to examine the pattern of pre-treatment problems. Three clusters of offenders, with distinctly different psychometric profiles, were identified depending upon the number and extent of their offence-specific and social adequacy problems. These were labelled Low need, Medium need and High need. Pre–post analyses revealed clinically significant treatment effects for the entire sample, with differing effects found across the clusters as follows: 50–81% of the Low need group scored within the cut-off (or normative range) at the post stage, while between 3% and 26% had shifted to a clinically significant degree; 34–75% of the Medium need group scored within the cut-off range after treatment, while between 9% and 100% had shifted to a clinically significant degree; 16–52% of the High need sample scored within the cut-off at the post-treatment stage, and between 15% and 80% had shifted to a clinically significant degree.     

Fertility and migration in the heart of the industrial revolution

Using research into the formation of industrial populations in the nineteenth century, this article examines the relationships between immigration and natality in Tilleur, an exemplary locality for studying the industrial revolution in Belgium. The main purpose is to test the general hypothesis positing a distinction between a foundation phase and a maturation phase in the process through which an industrial population is formed. The results are a contribution to the debate about the beginning of the fertility transition in industrial cities, and its relations to differential nuptiality and fertility in light of spatial origins.     

Costly,Regressive, and Ineffective: How Sensitive Is Public Support for the Mortgage Interest Deduction in the United States?

ABSTRACT

Although the mortgage interest deduction enjoys broad public support, critics argue that the policy disproportionately benefits wealthy households, fails to expand homeownership opportunities to households on the margins, and costs the federal government an extraordinary amount of money in foregone tax revenue. Drawing on data collected through an online experiment, this analysis tests the sensitivity of public support to these critiques. The findings reveal that support for the mortgage interest deduction declines when respondents are presented with information about the cost, effectiveness, or distribution of benefits associated with the deduction. Support among renters is more sensitive to framing effects than that among homeowners. Republicans are less sensitive to framing effects than Democrats when the deduction is framed as distributing benefits unequally, but more sensitive to these effects when the issue is framed as costly. However, all groups register their lowest level of support when told that the mortgage interest deduction is not an effective tool for expanding ownership opportunities.     

Intramedia Mediation: The Cumulative and Complementary Effects of News Media Use

This study focuses on one often overlooked political communication-based media effect, intramedia mediation, and the indirect effects that stem from relationships that exist among various forms of media use. Data from a 2000 national Annenberg election panel survey are used to assess a series of relationships between television and newspaper public affairs use and how these forms of media consumption affect citizens' knowledge of presidential campaign endorsements. The indirect effects that stem from the relationships that exist among these two forms of media use reflect the cumulative and complementary functions of mass communication consumption across time. An analysis of intramedia mediation in coordination with the study of the direct effects of public affairs media use on this study's outcome variable produces substantially larger overall effects for both forms of news use. Thus, the study of intramedia mediation contributes to a better understanding of the full range of media influences on a given outcome variable over the course of a political campaign. Ramifications of these findings are outlined and future lines of research summarized.     

Briefly Noted

The argument is commonly made that television has changed the character of parliamentary elections. Its ever more central role in election campaigns outside the United States is held to have “presidentialized” parliamentary elections because it is a medium that projects personalities more effectively than ideas or policies. A comparison of the electoral roles of the Australian prime minister and the U.S. president indicates that both leaders are held personally accountable for government performance. However, such “presidentialism” appears to have little to do with television in Australia or in the United States. Television‐dependent citizens in both countries are less susceptible to the campaign appeals of chief executives than the rest of the voting public. Both leaders, but especially the president, do have an electoral impact. Counter to expectations, however, this impact makes itself felt in both cases among those voters who are not dependent on television for their political information and cues. Party identification seems to insulate the television‐dependent more successfully against leader effects.
