Treatment Effect on Recidivism for Juveniles Who Have Sexually Offended: a Multilevel Meta-Analysis

The current study investigated the effect on recidivism of treatment aimed at juveniles who have sexually offended. It also assessed the potential moderating effect of type of recidivism, and several treatment, participant and study characteristics. In total, 14 published and unpublished primary studies, making use of a comparison group and reporting on official recidivism rates, were included in a multilevel meta-analysis. This resulted in the use of 77 effect sizes, and 1726 participants. A three-level meta-analytic model was used to calculate the combined effect sizes (Cohens d) and to perform moderator analyses. Study quality was assessed with the EPHPP Quality Assessment Tool for Quantitative Studies. A moderate effect size was found (d = 0.37), indicating that the treatment groups achieved an estimated relative reduction in recidivism of 20.5% as compared to comparison groups. However, after controlling for publication bias, a significant treatment effect was no longer found. Type of recidivism did not moderate the effect of treatment, indicating that treatment groups were equally effective for all types of recidivism. Also, no moderating effects of participant or treatment characteristics were found. Regarding study characteristics, a shorter follow up time showed a trend for larger effect sizes, and the effect size calculation based on proportions yielded larger effect sizes than calculation via mean frequency of offending. Implications for future research and clinical practice are discussed.     

On Empty Bathtubs: A Reply to Meehl

In the present state of ambiguity, negative studies of the validity of psychodiagnostic tests can easily be generated. But such studies throw little light upon the capacities of the tests and are confounded by the utilization of clinical interpretations. It would be most advisable to deal first with the central problems: the need for an integrated theory delineating tests in terms of the areas of optimum assessment and levels tapped; and, the development of realistic expectations on the part of clinicians. The studies frequently cited as throwing question upon the validity of projective tools are rejected on three grounds: the unrealistic wording of the hypotheses (i.e., are these tests valid or invalid, rather than under what circumstances and in what areas are the tests valid); the failure to consider the populations and the background experience of the clinician; and the methodological weaknesses in the designs of the studies. While the author admits that in the long run Meehl may turn out to be correct in suggesting that projective techniques have little value, at the present time Meehl's case for such a conclusion seems weak and should not serve as a deterrent for further investigations and proper utilization of projective techniques.     

Relations Between Minnesota Multiphasic Personality Inventory–A Scales and Rorschach Variables With the Scope and Severity of Maltreatment Among Adolescents

This study examined preexisting Rorschach (Exner, 2001) and Minnesota Multiphasic Personality Inventory–A (MMPI–A; Butcher et al., 1992) profiles to determine if selected MMPI–A scales and Rorschach variables would jointly associate with the number and severity of maltreatment subtypes (physical abuse, sexual abuse, neglect, and emotional maltreatment) of 157 adolescents (ages 14–17) with documented maltreatment histories. The Maltreatment Classification System was used to systematically code the maltreatment attributes. Six Rorschach variables (MOR, PER, Afr, SumY, SumC’, Human Content) were significantly correlated with the number of maltreatment subtypes, but none of the anticipated MMPI–A scales were related. MMPI–A Scale 7 and Rorschach variables Ego, MOR, and PER were jointly associated with physical abuse severity. MMPI–A Scale 0 and Rorschach variables MOR, PER, SumY, SumC’, PTI, Human Content, and Texture jointly associated with sexual abuse severity. This study supports the potential for certain MMPI–A scales and Rorschach variables to reflect the impact of adolescents’ maltreatment experiences in terms of the number and severity of types of maltreatment experienced. Because both instruments captured different aspects of adolescents’ maltreatment experiences, clinicians should consider using both when evaluating the impact of maltreatment on adolescents.     

Assessment of Long-Term Psychosocial Sequelae Among POW Survivors of the Korean Conflict

Psychological and psychiatric assessments were performed among 20 prisoner-of-war (POW) Korean-Conflict survivors. Results revealed extraordinary biological and psychological abuse with weight losses exceeding 35% of preservice weights and long-term cognitive, emotional, and behavioral sequelae. The full range of posttraumatic stress disorder symptoms was seen in 90% to 100% of the cases with high prevalence of co-morbidity, specifically mood (75%), other anxiety disorders. Documented by clinical investigators at (45%), and alcohol abuse (20%) POW release and now more than 30 years later, symptoms of apprehensiveness, confusion, detachment, and depression reflect the persistence of psychiatric morbidity over time.     

Vortex dynamics in La1.86Sr0. 14CuO4 studied by magnetoresistivity

Abstract

Vortex dynamics in La_1.86Sr_0.14CuO₄ have been studied by the measurement of ρ_c ^//i (T, H), where ρ_c ^//i is the c-axis resistivity for H//i (i = c or a-b). We argue that, at temperatures higher than the irreversibility temperature T _irr, the usual vortex picture breaks down owing to the thermal motion of vortices, resulting in a T- and T _in-dependent anisotropic parameter γ. After taking into account the dependence of γ on T and T _irr, we show that at each given temperature we can rescale the ρ_c ^//a-b (T, H) data onto the corresponding ρ_c ^//c (T, H) curves. This scaling property clearly indicates that the Lorentz-force-free mechanism is responsible for ρ_c ^//a-b (T, H). Furthermore, we also show that the measured ρ_c ^//a-b (T, H) data can be explained in terms of the recently developed extended Josephson coupling model which is verified by rescaling ρ_c ^//a-b (T) data for various fields onto a single curve.     

Scanning electron microscopy-electron channelling contrast investigation of recrystallization during cyclic deformation of ultrafine grained copper processed by equal channel angular pressing

Cyclic deformation has been performed at ambient temperature on ultrafine-grained copper processed by equal channel angular pressing. Observations by electron channelling contrast in a scanning electron microscope revealed that pronounced recrystallization occurred and several distinct dislocation configurations such as dislocation walls and labyrinth structures were found within the recrystallized regions. A model is proposed to account for the evolution of recrystallization, emphasizing that its development results from an interaction between the cyclic deformation and the growth of recrystallized regions. The formation of recrystallized regions of different sizes is discussed.     

PbO compensation in the growth of PbWO4: Y3+ crystals

The light yield of Y³⁺-doped PbWO₄ crystals increases after low-dose-rate irradiation with?γ?rays, and the radiation hardness is sensitive to annealing temperature. In the PWO growth procedure, an excess of PbO in the starting materials is a convenient method of compensating for PbO volatility. The relationship between the excess of PbO and the abnormal radiation behaviour has been investigated. The mechanism of the normal excess of PbO in the growth of PWO: Y³⁺ is discussed.     

Synthesis and evolution of crystalline garnet phases in Y3Sc5– x Ga x O12

Mixed-metal oxides with the composition Y₃Sc _x Ga_{5? x} O₁₂ (x?=?2.0, 2.1, 2.2, 2.25, 2.3, 2.4, 2.5, and 3.0) have been prepared by an aqueous sol–gel method. The effects of scandium substitution on the garnet phase formation were studied by IR spectroscopy and X-ray powder diffraction (XRD). The XRD data indicate that single-phase Y₃Sc _x Ga_{5? x} O₁₂ ceramic samples were obtained for x?=?2.0, 2.1, 2.2, 2.25, 2.3, and 2.4. The results also show that the formation of Y₃Sc _x Ga_{5? x} O₁₂ garnets depends on the molar ratio of scandium and gallium in the investigated composition, and consequently on the mean cationic radius at the Al³⁺ sites. The variation of lattice parameters for the Y₃Sc _x Ga_{5? x} O₁₂ phases with different x is reported.     

A Model of Infant Mood States and Sandarian Affective Waves

There has been little or no research on the establishment of infant moods or the mechanisms underlying them. One reason may be our difficulty in entertaining the idea that there are affective processes in infants that have long-lasting organizing continuous effects. It is this possibility that is considered in this paper. I attempt to address the questions of how moods are created and what some of their functions are. My model of moods is that infants have long-lasting (e.g., hours, days, and even longer) mood states. Mood states are dynamically changing yet distinct assemblages of affective behaviors. Mood control processes are modified by affective input from others. Thus moods are cocreated by the interplay of active, self-organized, biorhythmic affective control processes in the infant and the effect of the emotions expressed by others on mood control processes. In recognition of the importance of Sander's thinking to this work, I have named one of these processes the Sanderian Affective Wave. Mood states organize behavior and experience over time. Critically, moods serve an anticipatory representational function by providing directionality to an infant's behavior as he “moves” into the future. Thus they provide continuity to infants' experiential life. Furthermore, moods fulfill the Janus principle of bringing the past into the future for the infant, but as a noncognitive/symbolic/linguistic process—that is, as a purely affective–memorial process. Moreover, I believe that consideration of the development of moods opens the way for thinking about dynamic conflictual emotional processes in infants. Lastly, thinking about moods has important implications for understanding the development of pathology and for therapy.
