The impact of access to electricity on mental health in conflict-affected territories: An exploratory study in Gaza.

BACKGROUND: Access to affordable and clean energy is an essential component of the Sustainable Development Goals and a determinant of physical and mental health. However, the occupied Palestinian territory, the Gaza Strip, has experienced prolonged issues with electricity, water and gas supplies. This has significantly impacted on daily life and the area is on the verge of disaster. This research focused on the mental health effects of the lack of electricity in Gaza which have not been previously documented. METHODS: A cross-sectional analytic approach was adopted. A survey was administrated face-to-face with respondents from 350 participating households. Inferential statistical analysis was used to examine the relationship between the domains of anxiety, depression, wellbeing and electricity supply factors. A multiple linear regression model was also utilised. RESULTS: There is a highly statistically significant link between continuity of electricity and level of anxiety (p < .001). The same effect was reported in the level of depression, and a higher level was observed among residents with an intermittent or disrupted electricity supply, with a statistically significant link between the level of depression and continuity of electricity. CONCLUSION: Electricity issues, especially when combined with other stressors associated with living in Gaza, lead to serious mental health concerns. Urgent attention must be given to developing sustainable, reliable and affordable energy supplies for short- and long-term health and community development.

Cognitive Health Worries, Reduced Physical Activity and Fewer Social Interactions Negatively Impact Psychological Wellbeing in Older Adults During the COVID-19 Pandemic.

The Coronavirus pandemic has significantly affected psychological wellbeing in older adults, with cases of depression, anxiety and loneliness rising in the general population. Cognitive health has also potentially been affected, as social isolation can lead to cognitive decline. Worrying about cognitive health can be damaging to psychological wellbeing and is especially relevant to explore in the context of the Coronavirus pandemic. The objective of the present study was to explore the associations between cognitive health worries and wellbeing, and to investigate whether physical activity and social contact can mitigate negative effects of the pandemic on psychological wellbeing. Older adults (N = 191) completed an online survey which included measures of cognitive health worries, depression, anxiety, loneliness, social isolation, fatigue, impact of the Coronavirus pandemic, quality of life, subjective vitality, and physical activity. Analyses indicated that cognitive health worries, lower levels of physical activity and smaller amounts of social interaction were associated with poorer psychological and physical wellbeing. Results showed that worrying about cognitive health is associated with poorer wellbeing, and so interventions are needed to encourage positive cognitive functioning in times of social isolation. Promoting physical activity and social interaction is also beneficial, as results show that exercise and social contact are linked with improved wellbeing.

The Influence of Perfectionism, Self-Esteem and Resilience on Young People's Mental Health.

The current study explored whether maladaptive perfectionism and low self-esteem constituted reliable risk factors of student mental illness, as well as determining whether resilience moderates these predictive relationships. 434 University undergraduate students were recruited. Depression and anxiety were measured using the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Assessment (GAD-7). Perfectionism, self-esteem and resilience were analyzed in relation to the PHQ9 and GAD-7 scores via a regression analysis. Perfectionism discrepancy, self-esteem and resilience all significantly predicted depression and anxiety. Hierarchical regression analysis revealed a statistically significant amount of additional variance to be explained by resilience for depression and anxiety, than for perfectionism and self-esteem alone. Maladaptive perfectionism and low self-esteem predispose an individual to depression and anxiety, though resilience may act as a protective factor against development of mental illness.

The effect of age of acquisition on older individuals with and without cognitive impairments.

The present study compared the effects of age of acquisition (AoA) on object naming across groups of older individuals with cognitive impairments, healthy older controls, and young healthy controls. All participants named a set of 80 pictures, within which both AoA and frequency were manipulated orthogonally. Early-acquired objects were named faster than late-acquired objects across all groups. Response time also declined with age and with cognitive impairment between the groups. The effect of AoA differed across groups, with AoA effects being largest for the older group with cognitive impairments and smallest for the young control group. The present study adds strength to the suggestion that AoA of picture names is one of the factors that influence survival or loss of memories in dementia and cognitive decline, and this could therefore be used as a potential screening test for cognitive impairment disorders in the future.

Age-of-acquisition effects in novel picture naming: a laboratory analogue.

Age-of-acquisition (AoA) effects are such that early-acquired items are more quickly recognized and produced than later acquired items. In this laboratory analogue, participants were trained to name a group of Greeble pictures with a novel nonsense name. We manipulated order of acquisition of the stimuli: Half of the stimuli were presented from the onset of training (early acquired) whilst the other half were introduced later in the training schedule (late acquired). At test, when early and late stimuli had equal cumulative frequency, early stimuli were named significantly faster than late items. In a second test, it was also found that visual duration thresholds were significantly smaller for the early items when participants were asked to name the critical items. These findings support the notion that order-of-acquisition effects can be manifest over a short time span in the laboratory, and that the effect of order of acquisition is distinct from mere frequency of exposure. The findings are consistent with the idea that AoA effects occurring over a large temporal scale may be a special case of more general order-of-acquisition effects, and both may be a general property of learning mechanisms.

At home in early labour: what fathers do and how they feel--part 3.

This is the third in a series of three articles which present data from a 2010 survey completed by 263 fathers on their experience of being at home with their partner in early labour. Fathers' state of mind during early labour is explored. Anxiety levels are found to be high, particularly in regard to the wellbeing of their partners and babies. Attending antenatal classes does not appear to diminish anxiety and often, nor does speaking to a midwife in early labour. These results require cautious interpretation but also suggest that men need better preparation for their role in supporting mothers during labour.

At home in early labour: what fathers do and how they feel--part 1.

A survey of fathers from across the UK was carried out to explore their experience of being at home with their partners in early labour. Respondents were recruited via the Fatherhood Institute website and by contacting children's centres. Two hundred and sixty three men from diverse backgrounds responded. Approximately two fifths had found that early labour matched up to their expectations, but many fathers had been greatly or somewhat surprised by what happened. In terms of deciding when to leave home and go to the hospital or birth centre, fathers did not generally see themselves as the primary decision makers, but half had been either primarily or jointly responsible for the decision. There is therefore a strong case for ensuring that expectant fathers are given information when attending clinics or antenatal classes with their partners to help them understand the latent phase of labour and signs of established labour.

This is the second in a series of three articles which present data from a 2010 survey completed by 263 fathers on their experience of being at home with their partner in early labour. Fathers' state of mind during early labour is explored. Anxiety levels are found to be high, particularly in regard to the wellbeing of their partners and babies. Attending antenatal classes does not appear to diminish anxiety and nor does speaking to a midwife in early labour. These results require cautious interpretation but also suggest that men need better preparation for their role in supporting mothers during labour.

Intrinsic passive stiffness of 2 constructs of varus proximal femoral osteotomy: external fixator or blade plate.

BACKGROUND: Despite the published clinical evidence of the implementation of external fixation of proximal femoral osteotomies, there is lack of specific laboratory justification. METHODS: Two groups of 5 adult composite femur constructs of varus proximal femoral osteotomy were tested under incremental and cyclical loading of up to 600N along the mechanical axis. Five were fixed with a blade plate and another 5 with a monolateral external fixator. Load versus displacement curves were produced, and passive stiffness of all constructs was calculated. The described loading regime aimed to simulate the initial postoperative state and provide data for the assessment of vertical intrinsic passive stiffness in partial weight-bearing conditions. RESULTS: Although the blade plate constructs showed higher average stiffness, this was not statistically significant [F(1,8)=1.712, P=0.23]. No construct failed. No failure or plastic deformation was observed under the described loading regime. CONCLUSIONS: Vertical intrinsic passive stiffness in partial weight-bearing conditions during the initial postoperative period can be considered satisfactory subsequent to unilateral external fixation of a varus intertrochanteric osteotomy. CLINICAL RELEVANCE: The results support the hypothesis that external fixation is a biomechanically sound alternative to internal fixation of varus intertrochanteric osteotomies, in selected patients.

Age of acquisition, word frequency, and picture-word interference.

In two experiments participants named pictures superimposed with unrelated words. The age of acquisition (AoA) of the picture names was manipulated. Additionally, the word frequency (WF, Experiment 1) or AoA (Experiment 2) of the interfering distractor words was manipulated. Early-acquired pictures were named faster than their late-acquired counterparts. Both WF and AoA modulated the degree of interference from the irrelevant word; low-frequency and late-acquired words produced most interference. In neither case did the WF or AoA of the distractor word interact with the AoA of the picture. The results show that in the context of word processing both WF and AoA have similar effects.

The varying effects of age of acquisition.

There are a number of theories that suggest that age of acquisition (AoA) effects are not uniform across different tasks. Catling and Johnston (2006a) found greater AoA effects within an object-naming task than in a semantic classification task. They explained these findings by suggesting that AoA effects might accumulate according to how many levels of representation a task necessitates access to. Brysbaert and Ghyselinck (2006) explain the difference in AoA effects by proposing two distinct types of AoA (frequency dependent and frequency independent), the first accounted for by a connectionist-type mechanism and the latter situated at the interface between semantics and word production. Moreover, Moore, Smith-Spark, and Valentine (2004) and Holmes and Ellis (2006) have suggested that there are two loci of AoA effects: at the phonological level and somewhere within the perceptual level of representation. Again, this could account for the varying degrees of AoA effects. This study sets about testing these ideas by assessing the effect size of AoA across a series of different tasks that necessitate access to various levels of representation. Experiments 1-4 demonstrate significant effects of AoA in a novel picture-picture verification task, an object classification task, a picture verification task, and an object-naming task. Experiment 5 showed no effects of initial phoneme on the naming of the critical objects used within Experiments 1-4. The implication of the varying AoA effect sizes found within Experiments 1-4 in relation to explanations of AoA are discussed.

Age of acquisition affects object recognition: evidence from visual duration thresholds.

The impact of age of acquisition (AoA) on object recognition was explored in three experiments measuring visual duration threshold (VDT) for the identification of pictures labelled with early and late acquired names. Participants viewed briefly displayed images preceded and followed by a pattern mask. The minimum display duration required for correct identification was shorter for pictures labelled with early names than for those labelled with late names. In Experiments 2 and 3 we explored the effects of two forms of visual degradation on VDT for pictures with early and late acquired names. Both degradation by superimposed visual elements, and degradation by contrast reduction extended VDT, but only the former interacted with AoA. We conclude that both AoA and degradation by superimposed visual elements affect the efficiency of visual object recognition, but only degradation by contrast and not AoA affects the efficiency of earlier pre-recognition processes.
