Clinically elevated depression scores do not produce negative attentional biases in caregivers of autistic children.

Objective: Depression scores in caregivers of autistic children often fall in the clinical range. The attention of clinically depressed individuals tends to be biased toward negatively toned information. Whether caring for an autistic child might also be characterized by a negative attentional bias was explored here.

Social support mediates the relationship between dispositional gratitude and psychological distress in caregivers of autistic children.

Grateful caregivers report lower levels of psychological distress. Social support, engendered by gratitude and buffering against stress, might mediate this effect. Here we explored whether the protective psychological effect of dispositional gratitude might be mediated by increased social support.

Seeing it my way: A perspective taking intervention alleviates psychological distress in caregivers of autistic children.

Cognitively empathic caregivers are able to take the perspective of their autistic child(ren) without experiencing vicarious distressing emotions, and typically report lower psychological distress. Taking the perspective of the autistic child might, through fostering cognitive empathy, might relieve caregivers' psychological distress. Here we explored whether autism perspective taking videos developed by the National Autistic Society (NAS), intended to raise public awareness about autism, might be effective, packaged as an intervention, for increasing caregivers' cognitive empathy and reducing their psychological distress.

Sleep disturbances and physical health problems in caregivers of children with ASD.

Objectives: Caregivers of children with autism spectrum disorder self-report more physical health problems than controls. Sleep disturbances are also more prevalent in caregivers, and are positively associated with physical health problems. The negative impact of caring for a child with ASD on physical health therefore, might occur indirectly via poorer sleep.

Exploring Inter-Instance Relationships within the Query Set for Robust Image Set Matching.

Image set matching (ISM) has attracted increasing attention in the field of computer vision and pattern recognition. Some studies attempt to model query and gallery sets under a joint or collaborative representation framework, achieving impressive performance. However, existing models consider only the competition and collaboration among gallery sets, neglecting the inter-instance relationships within the query set which are also regarded as one important clue for ISM.

Exploring the Moderating Role of Benefit Finding on the Relationship Between Child Problematic Behaviours and Psychological Distress in Caregivers of Children with ASD.

Caregivers of children with ASD often find benefits associated with their caregiving role, and benefit finding predicts lower distress. Child problematic behaviours (CPB), which positively predict caregivers' distress, are perceived to be being less problematic, or more manageable, by caregivers who find benefits. Benefit finding therefore might mitigate the negative psychological impact of CPB.

Affiliate stigma, perceived social support and perceived stress in caregivers of children with autism spectrum disorder: A multiple mediation study.

Background: Affiliate stigma negatively predicts social support, and positively predicts psychological distress, in caregivers of children with ASD. Whether the affiliate stigma-distress relationship occurs indirectly via social support however has not been explored.

Methods: A correlational design was used.

Objectively assessed prospective memory failures and diurnal cortisol secretion in caregivers of children with ASD.

Caregivers of children with autism spectrum disorder (ASD) self-report more prospective memory (PM) failures compared with controls. Subjective and objective measures of PM, however, tend to be poorly correlated. This study therefore explored the cognitive impact of caring for a child with ASD using the Cambridge Prospective Memory Test (CAMPROMPT), a more objective, performance-based assessment of PM failures.

Caregivers' characteristics and family constellation variables as predictors of affiliate stigma in caregivers of children with ASD.

Affiliate stigma is one risk factor for psychological distress in familial caregivers. Few studies however, and none involving caregivers in the UK and US, have explored caregivers' characteristics and family constellation variables as risk and protective factors for affiliate stigma. This study aimed to fill this gap.

Multi-Modal Joint Clustering With Application for Unsupervised Attribute Discovery.

Utilizing multiple descriptions/views of an object is often useful in image clustering tasks. Despite many works that have been proposed to effectively cluster multi-view data, there are still unaddressed problems such as the errors introduced by the traditional spectral-based clustering methods due to the two disjoint stages: 1) eigendecomposition and 2) the discretization of new representations. In this paper, we propose a unified clustering framework which jointly learns the two stages together as well as utilizing multiple descriptions of the data.

Computer face-matching technology using two-dimensional photographs accurately matches the facial gestalt of unrelated individuals with the same syndromic form of intellectual disability.

Background: Massively parallel genetic sequencing allows rapid testing of known intellectual disability (ID) genes. However, the discovery of novel syndromic ID genes requires molecular confirmation in at least a second or a cluster of individuals with an overlapping phenotype or similar facial gestalt. Using computer face-matching technology we report an automated approach to matching the faces of non-identical individuals with the same genetic syndrome within a database of 3681 images [1600 images of one of 10 genetic syndrome subgroups together with 2081 control images].

The Role of Social-Cognitive and Emotional Factors on Exclusive Breastfeeding Duration.

Background: Previous research has suggested that exclusive breastfeeding is likely to be predicted by social-cognitive variables and fear. However, there is little research assessing the role of regret and self-conscious emotions (e.g.

The role of social-cognitive and emotional factors on testicular self-examination.

Objective: This study determined the role of social-cognitive and affective factors in promoting testicular self-examination.

Methods: Male participants (N = 115) rated their perceptions of testicular cancer, social-cognitive variables (attitude, subjective norm, and perceived control), and their emotions towards testicular cancer (anxiety and shame) and testicular self-examination (anticipated regret and relief). Participants also stated whether or not they had performed a testicular self-examination within the last month.

The psychophysiological impact of childhood autism spectrum disorder on siblings.

Objective: The negative impact of caring for a child with autism spectrum disorder (ASD) on parents' psychophysiological functioning has been widely evidenced. However, siblings, who also face emotional, social and physical challenges associated with having a brother/sister with ASD, have been less widely studied. This study examined the psychophysiological impact of childhood ASD on siblings.

Discriminative Non-Linear Stationary Subspace Analysis for Video Classification.

Low-dimensional representations are key to the success of many video classification algorithms. However, the commonly-used dimensionality reduction techniques fail to account for the fact that only part of the signal is shared across all the videos in one class. As a consequence, the resulting representations contain instance-specific information, which introduces noise in the classification process.

Benchmarking human epithelial type 2 interphase cells classification methods on a very large dataset.

Objective: This paper presents benchmarking results of human epithelial type 2 (HEp-2) interphase cell image classification methods on a very large dataset. The indirect immunofluorescence method applied on HEp-2 cells has been the gold standard to identify connective tissue diseases such as systemic lupus erythematosus and Sjögren's syndrome. However, the method suffers from numerous issues such as being subjective, time consuming and labor intensive.

Sparse Coding on Symmetric Positive Definite Manifolds Using Bregman Divergences.

This paper introduces sparse coding and dictionary learning for symmetric positive definite (SPD) matrices, which are often used in machine learning, computer vision, and related areas. Unlike traditional sparse coding schemes that work in vector spaces, in this paper, we discuss how SPD matrices can be described by sparse combination of dictionary atoms, where the atoms are also SPD matrices. We propose to seek sparse coding by embedding the space of SPD matrices into the Hilbert spaces through two types of the Bregman matrix divergences.

A bag of cells approach for antinuclear antibodies HEp-2 image classification.

The antinuclear antibody (ANA) test via indirect immunofluorescence applied on Human Epithelial type 2 (HEp-2) cells is a pathology test commonly used to identify connective tissue diseases (CTDs). Despite its effectiveness, the test is still considered labor intensive and time consuming. Applying image-based computer aided diagnosis (CAD) systems is one of the possible ways to address these issues.

The effects of an anticipated challenge on diurnal cortisol secretion.

In healthy, non-challenged individuals, the secretion of cortisol typically follows a diurnal profile characterized by a peak in the period following waking (cortisol awakening response) and a gradual decline throughout the day. In addition, cortisol secretion is increased in response to acutely stressful stimuli, particularly stressors involving social evaluation. The current study is the first to assess the impact of an anticipated acute laboratory stressor upon the typical diurnal pattern of HPA activation and relationship to acute cortisol secretion.

Memory failures for everyday tasks in caregivers of children with autism.

The stress of caring for a loved one with chronic illness has been linked with impairments in cognitive processes such as attention and problem solving, though few studies have examined the impact on memory. Compromised cognition, in particular, aspects of everyday functioning such as remembering medical instructions and appointments, might affect caregivers' ability to maintain the consistency and quality of care needed by the child. A sample of 31 caregivers of children with autism and 51 parents of neuro-typical children completed an electronic survey assessing their levels of psychological distress and everyday memory.

Dynamically adaptive control system for bioanodes in serially stacked bioelectrochemical systems.

Microbial bioelectrochemical systems (BESs) use microorganisms as catalysts for electrode reactions. They have emerging applications in bioenergy, bioproduction, and bioremediation. BESs can be scaled up as a linked series of units or cells; however, this may lead to so-called cell reversal.

With a little help from my friends: psychological, endocrine and health corollaries of social support in parental caregivers of children with autism or ADHD.

Elevated psychological distress and concomitant dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has been implicated as one pathway that links the stress of caregiving with adverse health outcomes. This study assessed whether perceived social support might mitigate the psychological, endocrine and health consequences of caregiver stress in parents of children with autism and attention deficit hyperactivity disorder (ADHD). Parental caregivers completed measures of psychological distress, perceived availability of social support and physical health complaints.

The psychosocial, endocrine and immune consequences of caring for a child with autism or ADHD.

Research that has assessed the psychophysiological consequences of caregiver stress in young and middle aged caregivers, that is, in populations not contending with age associated decline of the endocrine and immune systems, has been scarce and yielded inconsistent findings. To extend work in this area, this study assessed the psychosocial, endocrine and immune consequences of caregiver stress in a cross sectional sample of young and middle aged caregivers of children with autism and attention deficit hyperactivity disorder (ADHD) compared against parents of typically developing children. Caregivers (n=56) and parent controls (n=22) completed measures of psychological distress (perceived stress, anxiety/depression), social support and physical health complaints.

Perceived stress, common health complaints and diurnal patterns of cortisol secretion in young, otherwise healthy individuals.

Research has frequently linked perceived stress with changes in subjective and objective measures of ill health; however, additional assessment should consider the physiological mechanisms mediating these effects. This study investigated whether differential patterns of cortisol secretion might partially mediate perceived stress related disparities in common health complaints in young, otherwise healthy individuals. To capture the kinds of health complaints commonly reported in this population, the Pennebaker Inventory of Limbic Languidness (PILL) was selected.
