The relationship between self‐harm and alexithymia

This paper presents a systematic review of the literature concerning the relationship between alexithymia and self‐harm. Fifteen studies were selected following a systematic search of relevant databases. Results indicate significantly higher levels of alexithymia in women who self‐harm compared with women who do not self‐harm. Studies of men were less conclusive and require further investigation. A subsample of the studies found that childhood abuse and bullying were more likely to be associated with self‐harm if alexithymia was present as a mediator. Other studies found that depression mediated between alexithymia and self‐harm. The results indicate that the poor emotional cognition and expression associated with alexithymia may increase vulnerability to self‐harm, particularly in women.     

Lifetime Abuse and Mental Health Among Older Persons: A European Study

This study aimed to investigate the association of lifetime abuse and mental health among older persons, considering associated factors (e.g., demographics) through a cross-sectional design. We recruited 4,467 women and men ages 60–84 years from 7 European cities. Mental health was measured with the Hospital Anxiety and Depression Scale, and abuse (psychological, physical, sexual, financial, and physical injuries) based on the Revised Conflict Tactics Scale and the UK survey of abuse/neglect of older people. Multiple logistic regression analyses showed that country of residence, low educational level, and experienced financial strain increased the odds of probable cases of anxiety and depression. Female sex, white-collar profession, and financial support by social/other benefits/or partner income were associated with higher odds of anxiety, while older age and experience of lifetime injury were associated with increased odds of depressive symptoms. The findings of this study indicate that socioeconomic factors, as well as experienced lifetime severe physical abuse leading to injuries, are significant in perceived mental health of adults in later life.     

Mixed-sided individuals with neuroticism sustain more unintentional injuries in India

Previous research has shown a positive association between unintentional injury liability and non‐right‐handedness (especially mixed‐handedness). Research has also shown neuroticism to be one of the main predictors of unintentional injuries. In the present study we investigated the relationship of the three variables—frequency of unintentional injuries, side bias, and neuroticism. Further, the study aimed at extending the findings of previous studies establishing a relationship between non‐right‐handedness and unintentional injuries to a similar pattern in other domains of side bias—footedness, eyedness, and earedness. Data were collected from a large sample (N = 3474) using the side bias questionnaire, the shorter version of Maudsley's Personality Inventory, and an unintentional injury checklist. Results revealed positive correlations between the frequency of unintentional injuries and mixed‐sidedness, followed by left‐sidedness and right‐sidedness in each of the four domains of side bias. Furthermore, an increase in the frequency of unintentional injuries was observed for mixed‐sided and left‐sided individuals with higher levels of neuroticism.     

BEHAVIORAL TREATMENT FOR PATHOLOGICAL GAMBLING IN PERSONS WITH ACQUIRED BRAIN INJURY

The present investigation examined a behavior‐analytic clinical treatment package designed to reduce the pathological gambling of 3 individuals with acquired brain injury. A prior history of pathological gambling of each patient was assessed via caregiver report, psychological testing, and direct observation of gambling behavior. Using an 8‐week one‐on‐one client—patient format, a treatment program was developed in which the patient learned about the antecedents, consequences, and motivating operations that controlled the emission of gambling behavior. Data were collected on both self‐report of gambling urges and behavior following therapy and during in situ gambling opportunities. The therapy program reduced urges to gamble and actual gambling for all patients. The potential of behavior‐analytic therapy for reducing the pathological gambling of patients with and without brain injury is discussed.     

Attention Bias for Threatening Information in Children Following a Distressing Medical Procedure

Attention bias is common in adults with post‐traumatic stress disorder (PTSD) but is less studied in children. Children (n = 22) who experienced a potentially distressing procedure in an outpatient clinic (removal of K‐wires from orthopaedic fractures) and a group of medically unwell children (illness group; n = 27) were compared with healthy controls (n = 32). Children's baseline level of PTS symptoms were indexed prior to the medical procedure, and again at 1‐week follow‐up. Immediately after the K‐wire removal, children completed a dot probe task using two categories of target words (medical threatening and emotionally threatening). While K‐wire children showed an overall bias away from negative words relative to healthy controls, the illness group did not significantly differ from healthy controls. Attention bias in K‐wire and illness groups was unrelated to later PTS symptoms.     

Time perception in severe traumatic brain injury patients: A study comparing different methodologies

In this study, we investigated time perception in patients with traumatic brain injury (TBI). Fifteen TBI patients and 15 matched healthy controls participated in the study. Participants were tested with durations above and below 1 s on three different temporal tasks that involved time reproduction, production, and discrimination tasks. Data variables analyzed included amount of errors, relative errors, and coefficient of variation. Both groups completed a neuropsychological battery that included measures of attention, working memory, and executive functions. Results revealed significant differences between groups on the time reproduction and discrimination tasks, whereas groups showed similar performance on the time production task. Correlation analyses showed involvement of attention, working memory and executive functions on the time reproduction and time discrimination tasks, but there was no involvement on the time production task. These findings suggest that TBI does not impact specific temporal function. Rather, impairments in attention, working memory and executive function abilities may explain lower temporal performance in people with TBI.     

Regional cortical volume and cognitive functioning following traumatic brain injury

There has been limited examination of the effect of brain pathology on subsequent function. The current study examined the relationships between regional variation in grey matter volume, age and cognitive impairment using a semi-automated image analysis tool. This study included 69 individuals with mild-to-severe TBI, 41 of whom also completed neuropsychological tests of attention, working memory, processing speed, memory and executive functions. A widespread reduction in grey matter volume was associated with increasing age. Regional volumes that were affected also related to the severity of injury, whereby the most severe TBI participants displayed the most significant pathology. Poorer retention of newly learned material was associated with reduced cortical volume in frontal, parietal, and occipital brain regions. In addition, poorer working memory and executive control performance was found for individuals with lower cortical volume in temporal, parietal, and occipital regions. These findings are largely in line with previous literature, which suggests that frontal, temporal, and parietal regions are integral for the encoding of memories into long-term storage, memory retrieval, and working memory. The present study suggests that automated image analysis methods may be used to explore the relationships between regional variation in grey matter volume and cognitive function following TBI.     

Characterization of Al/n-ZnO/p-Si/Al structure with low-cost solution-grown ZnO layer

We report the fabrication of Al/n-ZnO/p-Si/Al diode structures with a flower-like ZnO layer. The average grain size, microstrain and dislocation density in the ZnO layer were determined as 25?nm, 1.55?×?10^?3 and 3.23?×?10¹³?cm^?2, respectively. From absorption spectra, the optical band gap was found to be ～3.17?eV. A red shift was attributed to non-stoichiometry arising from Zn⁺² ions substituting for oxygen vacancies. The ideality factor was determined as 1.55. The barrier height was calculated as 0.71?eV from I–V characteristics and 0.73?eV using the Norde plots.     

High-pressure electrical resistivity behaviour of nanocrystalline perovskite (La,Sr)(Mn,Fe)O3

We report here the electrical resistivity of nanocrystalline perovskite-structured La–Sr manganites as a function of pressures up to 8?GPa, at room temperature. The nanocrystalline perovskite manganites were prepared by the sol–gel technique and found to have crystallite sizes of 12–18?nm. The pressure dependence of the electrical resistivity shows a first-order phase transition at 0.66(2)?GPa and a subtle phase transition between 3.5 and 3.8?GPa. The first-order transition at 0.66?GPa can be related to the transition from localized-electron to band magnetism.
