Dermestes maculatus (Coleoptera: Dermestidae) development under fluoxetine effect using two drug administration models

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.     

Jealousy,intimate abusiveness,and intrusiveness

An examination of self-report scales of 160 men and 76 of their partners or former partners found significant correlations between jealousy and abusiveness (for coupled dyads) or intrusiveness (for separated dyads). Jealousy was related to borderline personality and to MCMI-II measures of Post Traumatic Stress Disorder. Rejection sensitivity leading to pathological acts, such as abusiveness and intrusiveness, is seen as originating in early insecure attachment and exposure to shaming experiences.     

Intimate Partner Violence Victims’ Accuracy in Assessing their Risk of Re-abuse

Using four categories of accuracy (true positive, false positive, true negative, false negative), this study explored (1) how accurately intimate partner violence (IPV) victims are able to assess their risk of re-abuse; and (2) potential predictors of accuracy. Women seeking help for IPV (N = 246) rated the likelihood that they would experience physical re-abuse in the coming year and then reported 18 months later whether those risks had been realized. Victim assessments were more likely to be right than wrong, and were subject to neither a pessimistic nor optimistic bias. In the multivariate analysis, significant/marginally significant predictors of the accuracy categories were the history of violence from this and former partners, level of substance use, PTSD symptoms, and the recency of the violence. Among the more robust findings were the connection between level of stalking and true positives, and between substance use and false negatives. This study suggests that victim assessments have significant potential to inform practice, and deserve further exploration.

An Exploratory Study of Emotional Intelligence and Domestic Abuse

To date, there is no literature specifically addressing the relationship between spousal battering and emotional intelligence, a concept that captures the success, or lack thereof, of a person's functioning in their immediate environment. Forty-four men convicted of spousal assault and 76 undergraduate students completed the Emotional Quotient Inventory (EQ-i; R. Bar-On, BarOn Emotional Quotient Inventory: User's Manual, Multi-Health Systems, Inc., Toronto, 1997), the Propensity for Abusiveness Scale (PAS; D. G. Dutton, J. Fam. Violence 10(2): 203–221, 1995), and the Balanced Inventory of Desirable Responding (D. Paulhus, J. Pers. Soc. Psychol. 46: 598–609, 1984; Assessing Self-Deception and Impression Management in Self-Reports: The Balanced Inventory of Desirable Responding, Unpublished manual, University of British Columbia, Vancouver, Canada, 1988; In Measures of Personality and Social Psychological Attitudes, Academic Press, San Diego, CA, pp. 17–59, 1991). Results of this exploratory study indicate that batterers score significantly lower than the general population on all components of EQ-i. Additionally EQ-i total and subscale scores for both samples correlate negatively and significantly with scores on PAS, suggesting that deficits in various components of emotional intelligence are related to an increase in the propensity to be abusive. Implications for batterer treatment are discussed.     

The criminal justice response to wife assault

This paper reviews the criminal justice response to wife assault. By establishing a set of conditional probabilites for the reporting, detection, prosecution, and conviction for wife assault, the paper establishes that a “winnowing process” occurs that is not dissimilar to that reported for other crimes. The probability of wife assault being detected by the criminal justice system is about 6.5%. Given that it is detected, the probability of arrest is about 21.2% [comparable to a 20% arrest rate for a composite of 121 crimes reported by Hood and Sparks (1970)]. Subsequent conditional probabilities for conviction and punishment generate an aggregate probability that, given that an event of wife assault occurs, the perpetrator has a 0.38% chance of being punished by the courts. The policy implications of this review are that the greatest impact on wife assault recidivism reduction would be generated by police arrest rates regardless of court outcome. At present, however, it is not known whether this effect is produced by specific deterrence or by the didactic function of law. It is concluded that too little is known of the subjective states of wife assaulters to ascertain whether deterrence or some other mechanism accounts for the decreased recidivism reported after arrest.     

Two-Year Reliability of the Propensity for Abusiveness Scale

The Propensity for Abusiveness Scale (PAS; Dutton [1995a] J. Fam. Violence 10[2]: 203–221) has been shown to correlate with both physical and psychological abuse in a variety of samples including gay men, assaultive males, and male and female college students (Clift, 2001; Dutton et al., 2001). For the current study, 27 male and 37 female university students completed the PAS during the 1998–1999 and the 2000–2001 school years. A 2-year test–retest reliability coefficient of r = .851 was found for women and a reliability coefficient of r = .629 was found for men. The combined sample had a reliability coefficient of r = .774. Moderate test–retest reliability coefficients were also found for each of the subscales.     

MCMI Results for Batterers: A Response to Gondolf

Gondolph [Gondolf, E. W. (1999). J. Fam. Violence 14: 1–17] recently published MCMI-III results on men in batterer treatment groups that appeared to indicate much lower levels of psychopathology than previous studies. Gondolph concluded from these results that the existence of an abusive personality was debatable. Gondolph is mistaken in drawing conclusions about the abusive personality based solely on MCMI results. The assessment of the abusive personality is not based on this instrument. Also, respondents in Gondolph's study had extremely high Desirability scores on the MCMI-III, so even his estimates of the incidence of personality disorder are questionable. Current assessment of personality disorder has begun to steer away from self-report instruments such as the MCMI-III; this practice should be utilized in assessing batterers.
