Parental Social Bonds and Adolescents’ Convictions

Social control theory suggests that adolescents are more likely to deviate when their parental bonds are weak or broken. However, are strong bonds to unconventional parents also a protective factor, or do they increase the risk of delinquency? There is almost no empirical evidence on this puzzle. Combining Danish survey and register data (N = 2,677), this study uses fixed effects linear regressions and finds that parental convictions do not moderate the effect of strong parental social bonds. Rather, the main result shows that indirect supervision (mother knowing the adolescent’s friends) reduces the risk of child conviction, irrespective of maternal conviction.     

The force-driven harmonic oscillator model for energy-efficient locomotion in individuals with transtibial amputation

The force-driven harmonic oscillator (FDHO) model states that the driving force is minimum at the resonant period of an oscillator. By manipulating prosthetic mass, this study explored the compromise of resonant periods between the two legs in persons with unilateral traumatic transtibial amputation (TTA) at self-selected walking velocity (SSWV), with an aim to better understand the energy minimization mechanisms of walking. It was hypothesized that (1) SSWV was the most energy-efficient walking velocity (MEWV), (2) the stride period at SSWV (Ts) is a compromise between the resonant periods of the normal leg (Tn) and the prosthetic leg (Tp) when they are dissimilar. Eight subjects completed multiple-speed treadmill walking tests (at 53, 67, 80, 93, and 107 m/min) according to three mass conditions (60%, 80%, and 100% of the normal leg below-knee mass) in a random order. Oxygen consumption and stride period were measured, and SSWV was empirically determined. The MEWV, the speed with minimum energy expenditure per distance traveled, was derived from quadratic regression, and its stride period (Tm) was estimated. A theoretical compromise period (Tv) between Tn and Tp was predicted by a virtual single pendulum system based on Huygens' Law. Across different mass conditions, comparisons were made among: Ts, Tm, Tv, Tn, and Tp. Results showed that: (1) Ts was significantly different from Tm; (2) Ts was greater than both Tn and Tp; (3) no significant difference was found between Tm and Tn. Implications for amputee rehabilitation in terms of thigh muscle training and prosthesis development were discussed.     

On the naturalising of phenomenology

In the attempt to construct a scientific approach to consciousness, it has been proposed that transcendental phenomenology or phenomenological psychology be introduced into the framework of cognitive neuroscience. In this article, the consequences of such an approach in terms of basic assumptions, methods for the collection of data, and evaluation of the collected data are discussed. Especially, the proposed notions of mutual constraint and the second perso are discussed. It is concluded that even though naturalising of phenomenology might not prove impossible, the projec has not yet found a coherent basic ground.     

The effects of attention on speech perception: an fMRI study

Focusing of attention to a specific speech source plays an important role in everyday speech perception. However, little is known of the neuronal substrates of focused attention in speech perception. Thus, the present study investigated the effects on neuronal activation of directed attention to auditory stimuli that differed in semantic content. Using an event-related fMRI protocol, single vowels, three-phoneme pseudowords and three- and four-phoneme real nouns and words were randomly presented to the subjects during four different instructional conditions. One condition was passive listening without any specific instructions of focusing of attention. The other conditions were attention focused on either the vowels, the pseudowords or the words. Thus, the acoustic stimulation was constant across conditions. The subjects were 13 healthy adults. Functional MRI was performed with a 1.5 T scanner, using an event-related design. During passive listening, there were significant activations bilaterally in the superior temporal gyrus. Instruction to attend to the pseudowords caused activation in middle temporal lobe areas, extending more anterior compared to the activations seen during passive listening. Instruction to attend to the vowel sounds caused an increase in activation in the superior/medial temporal lobe, with a leftward asymmetry. Instruction to attend to the words caused a leftward asymmetry, particularly in the middle and superior temporal gyri. It is concluded that attention plays a modulatory role in neuronal activation to speech sounds, producing specific activations to specific stimulus categories that may act to facilitate speech perception.     

Effects of sex and sex roles on the perceived maladaptiveness of DSM-IV personality disorder symptoms

This study investigated the influence of sex on the perceived maladaptiveness of DSM-IV personality disorder criteria based on previous findings that inconsistency of symptoms with sex roles affects the perception of personality disorder symptoms. The effects of rater characteristics (i.e., sex, sex role) were also examined. A total of 161 undergraduates (65 men, 96 women) rated the diagnostic criteria according to how maladaptive they were for males (male condition), females (female condition), or without regard to sex (neutral condition that served as a baseline) using a 7-point scale. Participants' sex role was determined using the Bem Sex Role (1981a) Inventory. Dependent and depressive personality disorder criteria (trend for borderline) were rated more maladaptive for females than males, whereas obsessive-compulsive personality disorder criteria were rated more maladaptive for males than females. Participant sex and sex role had little or no significant effects on the ratings. Results are compared with those of previous research. Methodological issues and implications for the diagnosis of personality disorders are discussed.     

Classification of loneliness using the T‐ILS: Is it as simple as it seems?

Student well‐being is a growing issue in higher education, and assessment of the prevalence of conditions as loneliness is therefore important. In higher education and population surveys the Three‐Item Loneliness Scale (T‐ILS) is used increasingly. The T‐ILS is attractive for large multi‐subject surveys, as it consists of only three items (derived from the UCLA Loneliness Scale). Several ways of classifying persons as lonely based on T‐ILS scores exist: dichotomous and trichotomous classification schemes and use of sum scores with rising levels indicating more loneliness. The question remains whether T‐ILS scores are comparable across the different population groups where they are used or across groups of students in the higher education system. The aim was to investigate whether the T‐ILS suffers from differential item functioning (DIF) that might change the loneliness classification among higher education students, using a large sample just admitted to 22 different academy profession degree programs in Denmark (N = 3,757). DIF was tested relative to degree program, age groups and gender. The framework of graphical loglinear Rasch models was applied, as this allows for adjustment of sum scores for uniform DIF, and thus for assessment of whether DIF might change the classification. Two items showed DIF relative to degree program and gender, and adjusting for this DIF changed the classification for some subgroups. The consequences were negligible when using a dichotomous classification and larger when using a trichotomous classification. Therefore, trichotomous classification should be used with caution unless suitable adjustments for DIF are done prior to classification.     

Primary Care Behavioral Health Provider Training: Systematic Development and Implementation in a Large Medical System

The expansion of integrated, collaborative, behavioral health services in primary care requires a trained behavioral health workforce with specific competencies to deliver effective, evidence-informed, team-based care. Most behavioral health providers do not have training or experience working as primary care behavioral health consultants (BHCs), and require structured training to function effectively in this role. This article discusses one such training program developed to meet the needs of a large healthcare system initiating widespread implementation of the primary care behavioral health model of service delivery. It details the Department of Defense’s experience in developing its extensive BHC training program, including challenges of addressing personnel selection and hiring issues, selecting a model for training, developing and implementing a phased training curriculum, and improving the training over time to address identified gaps. Future directions for training improvements and lessons learned in a large healthcare system are discussed.     

Predictors of opposition to and support for the ordination of women: insights from the LDS Church

Female ordination is an important component of gender equality in Christian religious communities. While prior research has examined societal, institutional, and organisational factors that predict changes in ordination policies in Christian denominations, there is very little research examining individuals’ attitudes regarding the ordination of women. In this research, we use data from two surveys of members of The Church of Jesus Christ of Latter-day Saints (LDS) to examine the factors that predict attitudes towards the ordination of women using two polity-specific measures of support or opposition. Results indicate greater support for the ordination of women when framed in a way that takes into account LDS church governance. While several demographic variables predict attitudes towards ordination, the strongest correlate is perceptions of inequality.     

Effects of maternal postpartum depression in a well‐resourced sample: Early concurrent and long‐term effects on infant cognitive,language, and motor development

This study examined early and long‐term effects of maternal postpartum depression on cognitive, language, and motor development in infants of clinically depressed mothers. Participants were 83 mothers and their full‐term born children from the urban region of Copenhagen, Denmark. Of this group, 28 mothers were diagnosed with postnatal depression three to four months postpartum in a diagnostic interview. Cognitive, language, and motor development was assessed with the Bayley Scales of Infant and Toddler Development third edition, when the infants were 4 and 13 months of age. We found that maternal postpartum depression was associated with poorer cognitive development at infant age four months, the effect size being large (Cohen's d = 0.8) and with similar effects for boys and girls. At 13 months of age infants of clinical mothers did not differ from infants of non‐clinical mothers. At this time most (79%) of the clinical mothers were no longer, or not again, depressed. These results may indicate that maternal depression can have an acute, concurrent effect on infant cognitive development as early as at four months postpartum. At the same time, in the absence of other risk factors, this effect may not be enduring. The main weaknesses of the study include the relatively small sample size and that depression scores were only available for 35 of the non‐clinical mothers at 13 months.
