畸变产物耳声发射在伪聋鉴定中的应用

目的寻找识别伪聋的客观方法。方法运用畸变产物耳声发射技术(DPOAE)对伪聋组、正常对照组及感音神经性聋组进行畸变产物耳声发射测试。结果(1)正常对照组的平均检出率为94.00％,感音神经性聋组的检出率为22.00％,两组比较有显著性差异(P<0.01),提示感音神经性聋组患者,通过DPOAE检查,可以发现其听功能障碍。(2)伪聋组的平均检出率为93.00％,与正常对照组比较无显著性差异(P>0.01),提示通过DPOAE检查,可以识别伪聋。而且,当听力下降>50dB时,检出率为零,这更表明DPOAE技术对伪聋有识别作用。结论DPOAE作为识别伪聋的客观检查方法可应用于法医临床学活体损伤鉴定。     

When Am I My Group? Self-Enhancement Versus Self-Justification Accounts of Perceived Prototypicality

The tendency to view the self as a prototypic member of a group is thought to be at the foundation of many social psychological phenomena. Two opposing accounts of perceived prototypicality have been suggested in the psychological literature. The self-justification account portrays this as a defensive tendency that occurs in response to threatened group status. The self-enhancement account portrays this as a strategic tendency to associate the self with positively viewed groups. These competing views were tested using both a minimal group (Study 1) and a naturalistic group (Study 2). Both studies showed that perceived prototypicality increased with increasing group status. Moreover, the effect of status was moderated by group importance (Study 1) and behavioral choice (Study 2). Both interaction patterns supported the self-enhancement view, suggesting that people view themselves as prototypic group members when doing so will promote a positive identity. These findings contradict common statements in the social identity literature.

DEVELOPMENTAL TRAJECTORY GROUPS: FACT OR A USEFUL STATISTICAL FICTION?*

A rapidly growing literature in criminology and psychology uses a group‐based methodology to identify and analyze developmental trajectories. Some confusion has arisen about the interpretation of this novel statistical model and with it some degree of cautionary commentary. We begin with a discussion of the role of trajectory groups as a statistical device for approximating population differences in developmental trajectories. We then discuss three misconceptions about group‐based trajectory modeling that stem from misunderstandings about the approximating role of trajectory groups: (1) individuals actually belong to a trajectory group, (2) the number of trajectory groups is immutable, and (3) the trajectories of group members follow the group‐level trajectory in lock step. We also point out that groupbased statistical modeling is not bound at the hip to the testing of taxonomic theories, and can just as well be used to test nontaxonomic theories.     

Do drug users use less alcohol than non-drug users? A comparison of ethyl glucuronide concentrations in hair between the two groups in medico-legal cases

Two groups were selected from the remainder of hair samples that had been tested for drugs at TrichoTech for medico-legal cases: samples that tested negative (drug-negative group; N=42, age 33.4+/-7.2 years) and samples that tested positive for drugs (drug-positive group; N=57, age 32.5+/-8.8 years). A rapid, simple method to detect the ethanol metabolite, ethyl glucuronide (EtG) in hair has been developed. The hair samples were sectioned, and then submitted to overnight sonication in water. Samples then underwent SPE using anion exchange cartridges, followed by derivatisation with N,O-bis[trimethylsilyl]trifluoroacetamide (BSTFA), before confirmation by GC-MS/MS. The assay produced excellent linearity and sensitivity over the calibration range 0.02-1.0 ng/mg, assuming a 10 mg hair sample. The mean age of the two groups was not statistically different (p=0.575, Student t-test), indicating a homogeneous group. Twelve of the 57 (21.0%) hair samples of the drug-positive group tested positive for EtG, and 17 of the 42 (40.5%) hair samples of the drug-negative group tested positive for EtG. The mean concentration of EtG in the drug-positive group was 0.011 ng/mg compared to 0.107 ng/mg in the drug-negative group. When the full results of this study were subjected to statistical analysis it was shown that EtG levels in the drug-negative group were statistically higher than those found in the drug-positive group (p<0.05). This preliminary finding may be of use in the study of addiction and adds valuable data to previous studies regarding the use of EtG as a valuable marker for alcohol levels in hair.     

Treating Substance‐Abusing Parents: A Study of the Pima County Family Drug Court Approach

A geographical comparison‐group design was used to examine the effectiveness of the Pima County (Arizona) Court Assisted Treatment Services (CATS) program and its drug court intervention. The study compared the summary statistics for the volunteers to the family drug court (n=33) with a treatment‐refusal group (n=42) and a treatment‐as‐usual group (n=45) from a matched geographical area. The findings of this study indicate that the family drug court group had higher engagement and completion rates of residential treatment than was true of the other comparison groups. In addition, the volunteers to the family drug court group had fewer parental rights severed, a higher percentage of permanency decisions reached within one year, earlier permanency decisions, and a higher percentage of children placed with their parents. The implications of this study's findings for future evaluations of the components of a family drug court intervention are discussed.

A comparison of the neuropsychological profiles of adult male sex offenders and non-offenders with a learning disability

Abstract

The present study compared the neumpsychologlcal pmfiles of a group of adult male sex offenden with a laming disability (n-42) with a group of adult male non-offenders with a learning disability (n-42) using the Wechsler Adult Intelligence Scale - Revised (1986). The groups wen matched for full-scale IQ. Thc study found that the non-offender group had significantly higher Verbal 1Q scorn than the sex offender group. No significant differences wen found for Performance IQ. The non-ofinder group was also found to have significantly hlgher scores on the Vocabulary sub-test than the sex offender group and the sex offender group was found to have significantly higher scores on the ObJecr Assembly subtest than the non-ofinder group. Finally. the sex offender group was found to have a significantly lower Verbal IQ than Performance IQ. No significant Verbal-Performance discrepancy was found for the non-offender group. Possible implications of these findings are dlscusscd.     

Buying Amendments? Lobbyists' Campaign Contributions and Microlegislation in the Creation of the Affordable Care Act

When do campaign contributions matter? This article advances the claim that a group that gives campaign contributions to US Members of Congress is more likely to achieve legislative success when (1) a single legislator can deliver to the group (2) a private benefit (3) without attracting negative attention. Using an original data set based on the written comments of nearly 900 interest groups lobbying the US Senate Finance Committee on health reform legislation in 2009, I link group requests to corresponding legislation. The analysis shows a significant relationship between lobby groups' campaign contributions and their legislative success, and at distinct units of analysis—the group, the side, and the group-senator dyad. The relationship is particularly strong in predicting senators’ amendments in committee. The rare data presented here offer compelling evidence that interest groups' legislative victories are sometimes connected to campaign contributions in a way that previous studies could not identify.     

Bills from the Floor: Why Governing Party Groups Initiate their Own Legislation

In parliamentary systems, why do party groups of the government camp initiate their own bills instead of going through the cabinet? This article suggests that such governing party group bills occur for three reasons: (a) cabinets hand out bills to the parties on the floor; (b) party groups or MPs want to signal to constituencies; or (c) parties on the floor are dissatisfied with cabinet policy making. Arguing that the absolute and relative importance of these explanations varies with institutional context, country-specific hypotheses with regard to the number of governing party group bills in Germany are tested. As expected, mechanisms (a) and (c) are especially important in explaining the occurrence of governing party group legislation in Germany.     

Truth,Lies, and Videotape: An Investigation of the Ability of Federal Parole Officers to Detect Deception

The ability of a group of Canadian federal parole officers to detect deception was investigated over the course of 2 days of lie detection training. On the first day of training, 32 officers judged the honesty of 12 (6 true, 6 fabricated) videotaped speakers describing personal experiences, half of which were judged before and half judged after training. On the second day, 5 weeks later, 20 of the original participants judged the honesty of another 12 videotapes (again, 6 pre- and 6 posttraining). To isolate factors relating to detection accuracy, three groups of undergraduate participants made judgments on the same 24 videotapes: (1) a feedback group, which received feedback on accuracy following each judgment, (2) a feedback + cue information group, which was given feedback and information on empirically based cues to deception, and (3) a control group, which did not receive feedback or cue information. Results indicated that at baseline all groups performed at or below chance levels. However, overall, all experimental groups (including the parole officers) became significantly better at detecting deception than the control group. By the final set of judgments, the parole officers were significantly more accurate (M = 76.7%) than their baseline performance (M = 40.4%) as well as significantly more accurate than the control group (M = 62.5%). The results indicate that detecting deceit is difficult, but training and feedback can enhance detection skills.     

Can Callous-Unemotional Traits and Aggression Identify Children at High-Risk of Anti-Social Behavior in a Low Socioeconomic Group?

Frick et al. (2005) proposed that Callous-Unemotional (CU) traits may be an important personality dimension associated with youth offending. The goal of the present study was to examine whether CU traits were associated with risk factors for offending in a low SES sample of children aged 10 years to 11 years in New Zealand. Two subgroups were identified: one high (High-CU/Agg group) and one low (Low-CU/Agg group) on CU traits and aggression. Results showed that scores for the High-CU/Agg group were significantly worse compared to the Low-CU/Agg group on a range of measures including stress management, caregiver criminal convictions, and dysfunctional parenting. However, analyses revealed that the measure of aggression accounted for more unique variance compared to CU traits. Further research is needed with youths from low SES communities to develop a more robust profile of potential youth offenders.

Attachment-based practice with adults: understanding strategies and promoting positive change. A new practice model and interactive resource for assessment,intervention and supervision

Abstract

The purpose of this study was to test whether attachment styles change over the course of a sex offender-specific treatment programme for incarcerated adult male sex offenders. To measure attachment styles, 44 male sex offenders (treatment n = 26, waitlist n = 18) completed the Relationship Scales Questionnaire (RSQ) and the Adult Attachment Scale (AAS). The results indicated that treatment participants showed significant decreases in levels of anxious attachment measures from pre- to post-test. Furthermore, the results from the RSQ 2-factor showed that participants in the treatment group demonstrated a significant decrease in avoidant attachment levels at post-test compared to the waitlist group. The results from the AAS showed that participants in the treatment group demonstrated a significant decrease in dependent attachment levels at post-test compared to the waitlist group. Implications of results are discussed.     

Group Delinquency in The Netherlands: Some Findings from an Exploratory Study

The phenomenon of group delinquency is, by and large, still terra incognita in the Netherlands. This paper presents a number of findings from a recent Dutch study on this subject. The findings result from a literature review, a (re-)analysis of Dutch self-report data and a number of interviews with informants and group members. Co-offending (i.e. offences that are committed by more than one person) and groups as a (semi-)organised association are two aspects of group delinquency that are considered here. Groups of youths hanging around and causing nuisance are the most visible manifestation of group behaviour. In 1997, according to a large survey, 12% of the Dutch population indicated that trouble caused by youth groups is an 'often occurring problem'. Concerning actual offending (with others), Dutch self-report data indicate that rates of co-offending are highest with vandalism, drug-related offences, intimidation, arson and participating in riots. Interviews with informants suggest that there is often a gap in local knowledge of problematic or criminal groups. It would seem that group delinquency is not paid structural attention by the various authorities. Besides employing informants, another means of gaining insight into groups is by computer analysis, using police data. This study has also looked at the characteristics of youths who commit offences with others. Findings concerning age, sex, ethnic background, type of offender and, finally, social identity are reported. In conclusion, some suggestions on how to tackle group delinquency are discussed.     

Shortened versions of the Gudjonsson Suggestibility Scale meet the standards

Purpose. The Gudjonsson Suggestibility Scale (GSS; Gudjonsson, 1984, 1997 ) is a well‐established forensic tool for measuring interrogative suggestibility. However, one restriction of this tool is that it requires an extensive testing procedure. The present study examined whether shorter versions of the GSS yield similar results as the original GSS procedure. Methods. One group (N=20) was given a shortened version of the GSS that consisted of an immediate recall test and the specific questions. GSS scores in this group were compared with those in a group (N=20) that had the standard procedure which includes a retention interval and immediate and delayed recall tests. A third group (N=20) was administered a shortened procedure in which the 20 GSS questions immediately followed the GSS story. In the fourth group (N=20), participants were given the retention interval, but no recall tests were administered. Results. ANOVA showed no differences in GSS scores amongst the four groups. Post hoc power analyses indicated that these non‐significant findings were not the result of a power problem and that larger sample sizes are expected to yield comparable results. Further analyses showed that neither the retention delay nor the recall tests affected suggestibility scores. Conclusions. These results suggest that shortened procedures for administering the GSS may be employed in situations where time is a key factor.

National Medical Support Notice. Pension and Welfare Benefits Administration, Labor. Final rule

This document contains a final rule that promulgates a National Medical Support Notice to be issued by State agencies as a means of enforcing the health care coverage provisions in a child support order, and to be treated by plan administrators of group health plans as a qualified medical child support order under section 609(a) of Title I of the Employee Retirement Income Security Act (ERISA). Through this regulation, the Department of Labor (the Department) is implementing an amendment to section 609(a) of ERISA, made by section 401 of the Child Support Performance and Incentive Act of 1998 (CSPIA), Pub. L. 105-200. This rule will affect group health plans, participants in group health plans, noncustodial children of such participants, and State agencies that administer child support enforcement programs.     

Self-control strength in prison inmates with antisocial personality disorder

The present study aimed to examine the difference in self-control strength between individuals with and without antisocial personality disorder (ASPD) in a Chinese male prisoner sample. Thirty-seven male inmates who met the criteria for DSM-IV ASPD and 38 who did not were asked to watch a four-minute silent videotape of an interview, and ignore the words displayed on screen during the videotape to deplete their ego strength. A handgrip task was conducted both before and after watching the videotape, with participants’ time squeezing the handgrip being the dependent variable. Result showed a significant interaction between group (ASPD/no-ASPD group) and time (baseline/post-manipulation measure). The post-manipulation result was significantly worse than the baseline result for the ASPD group, but not for the no-ASPD group. These results indicate that tasks that contribute to ego depletion lead to a deficit of self-control strength in prisoners with ASPD.
