Special Considerations in the Adaptation of Cognitive Behavioral Therapy for Insomnia With Active-Duty U.S. Army Personnel

Insomnia is highly prevalent among active-duty military service members. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a well-established and effective treatment; however, research and treatment recommendations have primarily focused on civilian or veteran populations. A multitude of military-specific factors directly impact service members’ sleep and the subsequent treatment recommendations. This article provides treatment considerations for the use of CBT-I with active-duty U.S. Army personnel. First, an overview of the theoretical model of insomnia, including military-specific predisposing, precipitating, and perpetuating factors, is presented, followed by a review of common comorbid conditions among service members with insomnia. Finally, discussion focuses on considerations and strategies for implementing components of CBT-I with service members, managing sleep during deployments, and adjusting sleep to accommodate overnight duties. Additional training resources and supplemental video examples (with actors) are provided.     

A new conceptual model of asymmetry in motor performance for bidimensional fast-oscillating movements in selected variants of performance

Spatial characteristics and lateral differences between two upper extremities were investigated in unilateral graphical tasks involving fast oscillating movements in the vertical plane based on the model of restricted (less than 10 degrees) horizontal abduction adduction in the shoulder joint. The spatial locations of reversal points were used to identify two groups of motor performance: with big angles and gross vertical vectors (stretched accordion group), and small projectile angles with small vertical vectors (compressed accordion group). Both groups appeared in right and left arm performance. The former group had a strong pattern of distribution of big and small projectile angles which reflects a particular variant of execution with a significant difference between angles and intermittent big and small angles (BB). Two other variants of execution relating to specific angular patterns of performance were identified in the compressed accordion group: one (Bs) showed a big difference between big and small angles but without intermittance; the other (ss) had only small differences between magnitudes of angles. The Bs variant of execution was observed only in left-handed performance, whilst ss was typical of both extremities. The performances affiliated to the stretched accordion group with the BB variant of execution mostly operated with reciprocal cooperation between alterations of X and Y vectors for the right arm. Performance related to the same group with the Bs variant of execution used concurrent collaboration involving alteration of these vectors for the left arm. The compressed accordion group which deployed the ss variant of execution mostly displayed concurrent alteration of vectors irrespective of the side of performance. It is suggested that the spatial movement strategies might reflect several different schemes of motor control wherein coupling of oscillators controls vertical and horizontal movements. It is also proposed that specific subunits of the functional system of nervous elements responsible for the expression of spatial derivatives of motor programmes may exist at lower levels of the CNS and might be initiated by the left brain or by the cooperative activity of the left and right hemispheres.     

Challenging behaviors in young children: the father's role

In this study, the authors examined the parenting practices, developmental expectations, and stress levels of 136 fathers and the challenging and prosocial behaviors of their 1- to 5-year-old children. In addition, the authors systematically addressed fathers' qualitative concerns about their parenting. The authors divided the participants into 4 groups and controlled for family socioeconomic status (SES) and the focus child's gender. Results showed a significantly higher use of corporal and verbal punishment and parenting stress among lower income fathers. Secondary analyses demonstrated a significant effect of paternal disciplinary practices that emphasized the frequent use of corporal and verbal punishment on child behavior problems, regardless of SES level. On a positive note, fathers from both lower and higher SES groups had reasonable developmental expectations for their boys and girls, and they reported similar frequencies of their children's prosocial behavior. The authors discuss the need for early parent education programs that include fathers and that teach specific strategies to address child behavior problems.     

Memory for targets in a multilevel simulated environment: Evidence for vertical asymmetry in spatial memory

In two experiments, adult participants explored a symmetrical three-tiered computer-simulated building that contained six distinctive objects, two on each floor. Following exploration, the objects were removed, and the participants were asked to make direction judgments from each floor, indicating the former positions of the objects on that floor and on higher and lower floors. Relative tilt error scores indicated a bias, in that targets that were higher than the test location were judged as consistently lower than their actual positions and targets that were lower than the test location were judged as consistently higher than their actual positions. Absolute tilt errors revealed an asymmetry, with more accurate and less variable tilt errors for judgments directed to lower floors than for judgments directed to higher floors. Experiment 3 ruled out an account of the findings that does not relate them to spatial memory. The results suggest that the superiority of downward over upward spatial judgments, previously reported in two-dimensional visual-spatial tasks, extends to navigational spatial memory.     

Distinguishing bipolar depression, major depression, and schizophrenia with the MMPI-2 clinical and content scales

Clinical and content scales from the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) were used to examine the capacity of these scales to assist in the differential diagnosis of a sample of 212 psychiatric patients-137 with major depression; 43 with schizophrenia; and 32 with bipolar disorder, depressed state. Consistent with the previous literature, the clinical scales Depression (D), and Schizophrenia (Sc), and the content scales Depression (DEP), and Low Self-Esteem (LSE) best distinguished major depression from schizophrenia; the content scale DEP proved to be the most powerful predictor in distinguishing bipolar depression from schizophrenia. No clinical or content scale proved to be effective in distinguishing patients with bipolar depression from patients with major depression. In general, the content scales outperformed the clinical scales.     

The effect of colour congruency on shape discriminations of novel objects

Although visual object recognition is primarily shape driven, colour assists the recognition of some objects. It is unclear, however, just how colour information is coded with respect to shape in long-term memory and how the availability of colour in the visual image facilitates object recognition. We examined the role of colour in the recognition of novel, 3-D objects by manipulating the congruency of object colour across the study and test phases, using an old/new shape-identification task. In experiment 1, we found that participants were faster at correctly identifying old objects on the basis of shape information when these objects were presented in their original colour, rather than in a different colour. In experiments 2 and 3, we found that participants were faster at correctly identifying old objects on the basis of shape information when these objects were presented with their original part-colour conjunctions, rather than in different or in reversed part-colour conjunctions. In experiment 4, we found that participants were quite poor at the verbal recall of part-colour conjunctions for correctly identified old objects, presented as grey-scale images at test. In experiment 5, we found that participants were significantly slower at correctly identifying old objects when object colour was incongruent across study and test, than when background colour was incongruent across study and test. The results of these experiments suggest that both shape and colour information are stored as part of the long-term representation of these novel objects. Results are discussed in terms of how colour might be coded with respect to shape in stored object representations.     

Global Economy,Justice and Sustainability

Although this paper attends to some extent to the question whether the global economy promotes or impedes either justice or sustainability, its main focus is on the relationship between justice and sustainability. Whilst sustainability itself as a normative goal is about sustaining inter alia justice, justice itself requires intergenerationally the sustaining of the conditions of a good life for all. At the heart of this is a conception of justice as realising the basic rights of all–in contrast to a more demanding distributive principle or a less demanding principle of not violating the liberty rights or other basic rights of others. Although Pogge’s analysis that the global economy causes harm by failing to realise basic rights is seen as a useful challenge to common libertarian assumptions, the acceptance of other positive correlative duties, following Shue, is advocated. Insofar as the global economy fails to realise basic justice, the question is ‘how far can it realistically be changed?’ and this is a function partly of the moral attitudes of individuals at large.     

A case-control analysis of felony convictions among recreational drug users

This study applied an epidemiologic case-control design to the identification of variables predicting which subjects in a population of recreational drug users were likely to have a felony conviction. A sample of 158 self-identified drug users responded to the web-based DRUGNET survey from February, 1997 through June, 1998. In this sample of 704 U.S. citizens who reported using illicit drugs, 79 (11.2%) reported having a drug-related felony conviction. A further 52 (7.4%) subjects reported felony convictions not related to drugs. Control subjects were drawn from the same sample and matched to cases on sex, age, and ethnicity. Subjects with drug-related convictions differed significantly from controls on 13 variables and those with nondrug-related convictions differed on 11 variables out of the 82 used in this study. Although there are major limitations given the self-selection of the sample, the differences between the groups indicates that we should be wary in generalizing from the minority of drug users who are arrested or incarcerated to the population of drug users in general.
