A meta‐mood model of rumination and depression: Preliminary test in a non‐clinical population

Depressive rumination and trait meta‐mood (emotional attention, emotional clarity and emotional repair) have been suggested as vulnerability factors leading to depression, but less is known about the associations among them. In this study, we examined the relationships between trait meta‐mood, rumination and depressive symptomatology. Using structural equation analysis in a large sample of a non‐clinical population we found a preliminary test of the role of trait meta‐mood dimensions in rumination and depressive symptomatology. Results indicated that attention to feelings has two pathways in its relation with rumination and depressive mood. On the one hand, emotional attention was associated with emotional clarity, and emotional clarity with emotional repair, which was related to lower depressive symptomatology, in part, by reducing rumination. On the other hand, emotional attention was directly associated with ruminative thoughts which, in turn, were related to higher depressive mood. Findings are discussed in terms of the implications of beliefs about emotions in the treatment of depression.     

Der verborgene Gott in der Theologie Werner Elerts

The re-formulation of conflicts, it has been claimed, is an important step towards reaching reconciliation in countries torn by conflicts. In this article I shall discuss reconciliation on the basis of my analysis of the nationalist theology of Sr. Pinochet and the alternative theological canons of people living in poverty in post-dictatorial Chile.1 1. Lene Sj?rup, Pinochets gud – og de fattiges teologiske modstand (K?benhavn: Museum Tusculanum, 2008); Lene Sj?rup, “Pinochets stedfortrædende lidelse og forsoning,” in Vendepunkter: Religion mellem konflikt og forsoning (ed. Lene Sj?rup; Odense: Syddansk Universitetsforlag, 2007); Lene Sj?rup, ”Pinochet as protector of and martyr for Christianity in Chile,” Nordic Journal of Religion and Society 19/2 (2006), 43-55. Reconciliation in the classical theological sense, my analysis indicates, is in itself part of these canons and therefore also of national conflicts. Religion does, however, play a major global, national, local and individual role in conflict resolution. This, I argue, indicates that there is more to conflict resolution than different canons of reconciliation. Conflicts are perceived as not only rupturing horizontal relationships between humans, but also vertical relationships with the divine. Conflict resolution, therefore, also involves the reparation of this relation. This paper discusses, using Chile as an example, the theological importance of memory work, the redefinition of space, and ritual as a means of repairing horizontal, as well as vertical, relations.     

Hippocampal structure and human cognition: Key role of spatial processing and evidence supporting the efficiency hypothesis in females

Here we apply a method for automated segmentation of the hippocampus in 3D high-resolution structural brain MRI scans. One hundred and four healthy young adults completed twenty one tasks measuring abstract, verbal, and spatial intelligence, along with working memory, executive control, attention, and processing speed. After permutation tests corrected for multiple comparisons across vertices (p < .05), significant relationships were found for spatial intelligence, spatial working memory, and spatial executive control. Interactions with sex revealed significant relationships with the general factor of intelligence (g), along with abstract and spatial intelligence. These correlations were mainly positive for males but negative for females, which might support the efficiency hypothesis in women. Verbal intelligence, attention, and processing speed were not related to hippocampal structural differences.     

A system for automatic recording and analysis of motor activity in rats

We describe the design and evaluation of an electronic system for the automatic recording of motor activity in rats. The device continually locates the position of a rat inside a transparent acrylic cube (50 cm/side) with infrared sensors arranged on its walls so as to correspond to the x-, y-, and z-axes. The system is governed by two microcontrollers. The raw data are saved in a text file within a secure digital memory card, and offline analyses are performed with a library of programs that automatically compute several parameters based on the sequence of coordinates and the time of occurrence of each movement. Four analyses can be made at specified time intervals: traveled distance (cm), movement speed (cm/s), time spent in vertical exploration (s), and thigmotaxis (%). In addition, three analyses are made for the total duration of the experiment: time spent at each x–y coordinate pair (min), time spent on vertical exploration at each x–y coordinate pair (s), and frequency distribution of vertical exploration episodes of distinct durations. User profiles of frequently analyzed parameters may be created and saved for future experimental analyses, thus obtaining a full set of analyses for a group of rats in a short time. The performance of the developed system was assessed by recording the spontaneous motor activity of six rats, while their behaviors were simultaneously videotaped for manual analysis by two trained observers. A high and significant correlation was found between the values measured by the electronic system and by the observers.     

The impact of mindfulness on well-being and performance in the workplace: an inclusive systematic review of the empirical literature

Work can be demanding, imposing challenges that can be detrimental to the physical and mental health of workers. Efforts are therefore underway to develop practices and initiatives that may improve occupational well-being. These include interventions based on mindfulness meditation. This paper offers a systematic review of empirical studies featuring analyses of mindfulness in occupational contexts. Databases were reviewed from the start of records to January 2016. Eligibility criteria included experimental and correlative studies of mindfulness conducted in work settings, with a variety of well-being and performance measures. A total of 153 papers met the eligibility criteria and were included in the systematic review, comprising 12,571 participants. Mindfulness was generally associated with positive outcomes in relation to most measures. However, the quality of the studies was inconsistent, so further research is needed, particularly involving high-quality randomized control trials.     

Validation of Dating Violence Questionnarie-R (DVQ-R)

Background/Objective

Despite the growing interest in the study of dating violence, relatively few psychometrically sound instruments are available to researchers. To provide an instrument to researchers and professionals to assess victimization in dating relationships, with adequate psychometric properties. Method: Participants were 6,138 adolescents drawn from the general population, 25% of which were university students. Participants responded to the original Dating Violence Questionnaire (DVQ). Results: Confirmatory analyses results provided evidence of a clear factorial structure that was invariant through sex groups. The DVQ-R measures with 20 items five dimensions of abuse in affective interpersonal relationships of adolescents and youth: Detachment, Humiliation, Coercion, Physical and Sexual violence. Internal consistency indexes were adequate for both each one of the five dimensions as well as for the general scale. Conclusions: The DVQ-R is an useful assessment to be applied in adolescents and youth. Implications for research and intervention are discussed in light of the results obtained.     

Improving executive function using transcranial infrared laser stimulation

Transcranial infrared laser stimulation is a new non‐invasive form of low‐level light therapy that may have a wide range of neuropsychological applications. It entails using low‐power and high‐energy‐density infrared light from lasers to increase metabolic energy. Preclinical work showed that this intervention can increase cortical metabolic energy, thereby improving frontal cortex‐based memory function in rats. Barrett and Gonzalez‐Lima (2013, Neuroscience, 230, 13) discovered that transcranial laser stimulation can enhance sustained attention and short‐term memory in humans. We extend this line of work to executive function. Specifically, we ask whether transcranial laser stimulation enhances performance in the Wisconsin Card Sorting Task that is considered the gold standard of executive function and is compromised in normal ageing and a number of neuropsychological disorders. We used a laser of a specific wavelength (1,064 nm) that photostimulates cytochrome oxidase – the enzyme catalysing oxygen consumption for metabolic energy production. Increased cytochrome oxidase activity is considered the primary mechanism of action of this intervention. Participants who received laser treatment made fewer errors and showed improved set‐shifting ability relative to placebo controls. These results suggest that transcranial laser stimulation improves executive function and may have exciting potential for treating or preventing deficits resulting from neuropsychological disorders or normal ageing.
