Enhancing student performance and employability through the use of authentic assessment techniques in extra and co-curricular activities (ECCAs)

The paper advocates the use of authentic assessment techniques, delivered in extra and co-curricular activities (ECCAs), to augment and improve student performance on academic law degree programmes. A combination of formative and summative methods in ECCA assessment provides the optimum environment to measure and improve the crucial critical reasoning skill – the key transferable skill to academic degree success. This skill, when developed in students, is also highly prized by prospective employers, and therefore, the use of authentic assessment improves graduate employability rates.     

Comparing the Scoring of Human Decomposition from Digital Images to Scoring Using On‐site Observations

When in forensic casework or empirical research in‐person assessment of human decomposition is not possible, the sensible substitution is color photographic images. To date, no research has confirmed the utility of color photographic images as a proxy for in situ observation of the level of decomposition. Sixteen observers scored photographs of 13 human cadavers in varying decomposition stages (PMI 2–186 days) using the Total Body Score system (total n = 929 observations). The on‐site TBS was compared with recorded observations from digital color images using a paired samples t‐test. The average difference between on‐site and photographic observations was ?0.20 (t = ?1.679, df = 928, p = 0.094). Individually, only two observers, both students with <1 year of experience, demonstrated TBS statistically significantly different than the on‐site value, suggesting that with experience, observations of human decomposition based on digital images can be substituted for assessments based on observation of the corpse in situ , when necessary.     

The provenance of émigrés: the validity of measuring knowledge of places

Establishing the origin of those seeking asylum is essential but difficult as asylum seekers often cannot corroborate their origin claim with documents. The aim of the present study was to assess whether asking knowledge questions, sketch questions and impossible questions are valid methods to determine the veracity of an origin claim. Participants (N?=?105) from Tilburg (truth-tellers), Maastricht (partial liars) and Gothenburg (full liars) were asked to convince an interviewer that they originated from Tilburg. Half of them prepared and half of them did not prepare themselves for the interview. They were asked 10 knowledge questions typically asked to assess the credibility of origin claims, 4 impossible questions and 1 sketch question. Participants from Tilburg answered more questions correctly than participants from Maastricht and Gothenburg. Performance also improved with preparation. Even though the results did provide some support for the validity of assessing claims about origin by asking knowledge questions, the differences between the groups were modest, and it was impossible to correctly identify all truth-tellers and liars. Changing the output modality from verbal answering to sketching contributed to the credibility assessment of origin claims, whereas impossible questions were not discriminatory.     

Risk factors for stalking violence,persistence, and recurrence

This study used a retrospective design to investigate risk factors associated with violence during a stalking episode, persistence (increased duration of stalking) and recurrence (multiple subsequent separate stalking episodes) in 157 people (91% male, mean age 35 years) with an established history of stalking behaviour. Results showed that diverse risk factors are associated with different types of stalking outcomes. Consistent with previous research, stalking violence was more likely to occur when the victim was an ex-intimate, when explicit threats had been made and where there had been previous property damage (AUC = .74). Personality disorder, older age, criminal versatility, a prior acquaintanceship and erotomanic delusions (AUC = .75) predicted stalking recurrence. Finally, previous acquaintanceship, the presence of delusional beliefs and the absence of a history of physical or sexual violence were associated with stalking persistence. These results clearly show that effective assessment and management of stalking requires consideration of different stalking outcomes and the diversity of associated risk factors.     

Shooting Alone: The Pre‐Attack Experiences and Behaviors of U.S. Solo Mass Murderers

This paper outlines the sociodemographic, developmental, antecedent attack, attack preparation, and commission properties of 115 mass murderers between 1990 and 2014. The results indicate that mass murderer attacks are usually the culmination of a complex mix of personal, political, and social drivers that crystalize at the same time to drive the individual down the path of violent action. We specifically focus upon areas related to prior criminal engagement, leakage, and attack location familiarity. Whether the violence comes to fruition is usually a combination of the availability and vulnerability of suitable targets that suit the heady mix of personal and political grievances and the individual's capability to engage in an attack from both a psychological and technical capability standpoint. Many individual cases share a mixture of unfortunate personal life circumstances coupled with an intensification of beliefs/grievances that later developed into the idea to engage in violence.     

Assessing the Risk of Domestic Violence Reoffending: A Validation Study

Little research has been conducted to validate available instruments for assessing the risk of domestic violence reoffending, especially research using some form of prospective design. This study uses a prospective design to determine the reliability and validity of the Domestic Violence Screening Instrument (DVSI). The analysis is based on a sample of 1,465 male domestic violence offenders selected consecutively over a 9-month period. Data on reoffending were collected in a 6-month follow-up period from a subsample of the victims (N = 125) of these perpetrators and from official records for all perpetrators during an 18-month follow-up period. The empirical results suggest that the DVSI was administered reliably, and they provide significant evidence of the concurrent, discriminant, and predictive validity of this instrument. Implications for further research and utilization of the DVSI are discussed.     

Static and Dynamic Patient Characteristics as Predictors of Criminal Recidivism: A Prospective Study in a Dutch Forensic Psychiatric Sample

If clinicians in forensic psychiatry want to reduce risk of reoffending in their patients, they require insight into dynamic risk factors, and evidence that these add predictive power to static risk indicators. Predictors need to be evaluated under clinically realistic circumstances. This study aimed to validate dynamic and static variables as predictors of reconviction in a naturalistic outcome study. Data on static and dynamic risk factors were collected for 151 patients discharged from Dutch forensic psychiatric hospitals. Community follow-up was prospective, with a 5.5 year minimum. A prediction model was developed using Cox regression analysis. The magnitude of the predictive power of this model was estimated using receiver operating characteristic (ROC) analysis. The final prediction model contained four static and no dynamic predictors. The model's ROC area under the curve was .79 (95% CI .69–.89). Clinical risk ratings were non-predictive. Post hoc analyses exploring the influence of subgroups of patients did not yield better models. It is concluded that a small set of static predictors yielded a good estimate of future reconvictions; inclusion of dynamic predictors did not add predictive power.     

Decision-Making About Volitional Impairment in Sexually Violent Predators

The Kansas v. Hendricks (1997) decision, in which the Supreme Court authorized post-sentence civil commitment for certain sex offenders, appeared to be constitutionally legitimized by limiting the class of offenders eligible for this special form of civil commitment to those who are "unable to control" their dangerousness. Nowhere in the available record, however, did the Court elucidate what they meant by this notion of volitional impairment. This study sought to examine factors that legal professionals (n=43), psychologists (n=40), and mock jurors (n=76) deem most relevant to a determination of sex offender volitional impairment. Participants, who were randomly assigned to a sexual predator commitment or an insanity hearing context, read a series of 16 vignettes that described a pedophilic offender and included combinations of variables hypothesized to be related to judgments of volitional impairment. Results suggested that participants, who as a group made remarkably high estimates of likelihood of future sexual violence, considered verbalization of control, history of sexual violence, and the context of the hearing as highly relevant to determinations of volitional impairment. Implications for policy and practice are explored.     

Comparing Effect Sizes in Follow-Up Studies: ROC Area,Cohen's <Emphasis Type="Italic">d</Emphasis>, and <Emphasis Type="Italic">r</Emphasis>

In order to facilitate comparisons across follow-up studies that have used different measures of effect size, we provide a table of effect size equivalencies for the three most common measures: ROC area (AUC), Cohen's d, and r. We outline why AUC is the preferred measure of predictive or diagnostic accuracy in forensic psychology or psychiatry, and we urge researchers and practitioners to use numbers rather than verbal labels to characterize effect sizes. Strictly speaking, d values pertain only to variables scored on an interval scale. When the nondichotomous variable is ordinally scaled, r or AUC should be used. Nevertheless, the values in Table 1 allow one to compare the relative magnitudes across studies that have reported any of the three effect size measures.     

Risk assessment vs real prediction: The prediction problem and public trust

Confusing risk assessment and the prediction of individual behavior has led to false claims which, if translated into juvenile court or adult sentencing policies (selective incapacitation, for example), may lead to further erosion in public confidence in the justice system. Considerable emphasis has been placed on the consequences of false positives in the literature and in this paper. The false negative has different but equally damaging effects because the impression may be given that increasing the severity of sanctions for selected serious offenders is the solution to juvenile delinquency and adult crime. Analysis of official police records for three birth cohorts from Racine, Wisconsin, reveals that, although high-risk groups produce a disproportionate share of the delinquent and criminal behavior recorded in police reports and juveniles in high-risk groups continue into adult crime disproportionately to others, serious juvenile offenders still account for only a portion of the serious offenses that will ultimately be committed by adults. Therefore, selective incapacitation of early offenders may take only a small bite out of crime. When referrals rather than police contacts were utilized as the predictor variable, there was little difference in predictive efficiency.
