Karin Wachter, Lauren E Gulbas
In 2016, researchers conducted a qualitative study in a mid-sized town in the United States to address gaps in research and practice related to psychosocial consequences of forced migration among women. The loss of social support and its impacts on the well-being of women are rarely addressed in refugee resettlement policy or practice overwhelmingly concerned with economic self-sufficiency. The study sought to develop theory to explain how women (n = 27) who migrated from the Democratic Republic of the Congo recreate social support post-resettlement in the United States...

Even though ambiguous words are common in languages, children find it hard to learn homophones, where a single label applies to several distinct meanings (e.g., Mazzocco, 1997). The present work addresses this apparent discrepancy between learning abilities and typological pattern, with respect to homophony in the lexicon. In a series of five experiments, 20-month-old French children easily learnt a pair of homophones if the two meanings associated with the phonological form belonged to different syntactic categories, or to different semantic categories...

Stress associated with social isolation in early life can lead to disturbances in the emotional regulation in adult rats. However, there are no reports on the impact of isolation from the mother while providing contact with peers. Under such conditions, young individuals have the opportunity to interact with others, are able to develop social behaviour, etc. Yet, there is no stimulation and care provided by the mother. We examined the relative impact of maternal contact and sibling contact in the rarely studied pre-juvenile (3rd and 4th week post birth) period on subsequent development...

Sensory-specific satiety (SSS) refers to a decline in pleasantness of eaten foods in comparison to other non-ingested meals. Although SSS is specific to the eaten food, it can also generalize to other meals that share similar properties to the satiated food. It is possible that this phenomenon could become more specific after extensive experience, as repeated exposure to an assortment of similar food could cause perceptual learning (i.e. an increase in the distinctiveness of each specific item). This in turn would reduce generalization from the consumed food to other similar products, so they will be more readily consumed...

Though technology plays an increasingly important role in modern health systems, human performance remains a major determinant of safety, effectiveness and efficiency of patient care. This is especially true in the delivery room. Thus, the training of professionals must aim not only for the acquisition of theory and practical skills on an individual basis, but also for the learning of teamwork systematically. Training health professionals with simulation enhances their theoretical knowledge and meets formal requirements in literacy, technical skills and communication...

BACKGROUND AND PURPOSE: Factors contributing to safety- or quality-related incidents (e.g. variances) in children are unknown. We identified clinical and RT treatment variables associated with risk for variances in a pediatric cohort. MATERIALS AND METHODS: Using our institution's incident learning system, 81 patients age ≤21 years old who experienced variances were compared to 191 pediatric patients without variances. Clinical and RT treatment variables were evaluated as potential predictors for variances using univariate and multivariate analyses...

BACKGROUND: Epilepsy is a common neurological disorder and is not well controlled by available antiepileptic drugs (AEDs). Inflammation is considered to be a critical factor in the pathophysiology of epilepsy. Sinomenine (SN), a bioactive alkaloid with anti-inflammatory effect, exerts neuroprotective activity in many nervous system diseases. However, little is known about the effect of SN on epilepsy. METHODS: The chronic epilepsy model was established by pentylenetetrazole (PTZ) kindling...

Tatsuro Kawamoto
The assumption that the values of model parameters are known or correctly learned, i.e., the Nishimori condition, is one of the requirements for the detectability analysis of the stochastic block model in statistical inference. In practice, however, there is no example demonstrating that we can know the model parameters beforehand, and there is no guarantee that the model parameters can be learned accurately. In this study, we consider the expectation-maximization (EM) algorithm with belief propagation (BP) and derive its algorithmic detectability threshold...

Danny Spampinato, Pablo Celnik
Acquiring complex motor skills involves learning a number of distinct motor components. Two fundamental elements that constitute a skill are the internal representation (i.e., the calibration of a sensorimotor map) and the sequence of movements needed to execute the task. Learning each of these likely rely on different neural substrates such as the cerebellum and primary motor cortex (M1), and physiological mechanisms. However, the specific neurophysiological processes underlying the acquisition of these components remains poorly understood...

REVIEW
Amy M LeMessurier, Daniel E Feldman
That experience shapes sensory tuning in primary sensory cortex is well understood. But effective neural population codes depend on more than just sensory tuning. Recent population imaging and recording studies have characterized population codes in sensory cortex, and tracked how they change with sensory manipulations and training on perceptual learning tasks. These studies confirm sensory tuning changes, but also reveal other features of plasticity, including sensory gain modulation, restructuring of firing correlations, and differential routing of information to output pathways...

BACKGROUND: Low back pain (LBP) is commonly associated with paraspinal muscle dysfunctions. A method to study deep lumbar paraspinal (i.e. multifidus) muscle function and neuromuscular activation pattern is intramuscular electromyography (EMG). Previous studies have shown that the procedure does not significantly impact muscle function during activities involving low-level muscle contractions. However, it is currently unknown how muscular function and activation are affected during high-exertion contractions...

Verb bias-the co-occurrence frequencies between a verb and the syntactic structures it may appear with-is a critical and reliable linguistic cue for online sentence processing. In particular, listeners use this information to disambiguate sentences with multiple potential syntactic parses (e.g., Feel the frog with the feather.). Further, listeners dynamically update their representations of specific verbs in the face of new evidence about verb-structure co-occurrence. Yet, little is known about the biological memory systems that support the use and dynamic updating of verb bias...

Through same-different judgements, we can discriminate an immense variety of stimuli and consequently, they are critical in our everyday interaction with the environment. The quality of the judgements depends on familiarity with stimuli. A way to improve the discrimination is through learning, but to this day, we lack direct evidence of how learning shapes the same-different judgments with complex stimuli. We studied unsupervised visual discrimination learning in 42 participants, as they performed same-different judgments with two types of unfamiliar complex stimuli in the absence of labeling or individuation...

BACKGROUND: The implantable cardioverter defibrillator provides effective treatment for the prevention of sudden cardiac arrest but significant risks associated with transvenous implantation persist. The subcutaneous implantable cardioverter defibrillator has proven to be an alternative and innovative treatment option for select patients to mitigate these risks. Obtaining the patients' perspectives can provide clinicians with essential information to guide implant selection, procedural decision-making, and support patient management...

The ability to restrain a prepotent response in favor of a more adaptive behavior, or to exert inhibitory control, has been used as a measure of a species' cognitive abilities. Inhibitory control defines a spectrum of behaviors varying in complexity, ranging from self-control to motoric self-regulation. Several factors underlying inhibitory control have been identified, however, the influence of neophobia (i.e., aversion to novelty) on inhibitory control has not received much attention. Neophobia is known to affect complex cognitive abilities, but whether neophobia also influences more basic cognitive abilities, such as motoric self-regulation, has received less attention...

The GO-Cellular Component (GO-CC) ontology provides a controlled vocabulary for the consistent description of the subcellular compartments or macromolecular complexes where proteins may act. Current machine learning-based methods used for the automated GO-CC annotation of proteins suffer from the inconsistency of individual GO-CC term predictions. Here, we present FGGA-CC+ , a class of hierarchical graph-based classifiers for the consistent GO-CC annotation of protein coding genes at the subcellular compartment or macromolecular complex levels...

Whether accelerated long-term forgetting (ALF) and classic organic amnesia, particularly hippocampal-amnesia, differ qualitatively or merely quantitatively is disputed. Qualitative difference accounts postulate that ALF patients show normal recall memory for at least minutes, during which hippocampal-amnesics already show accelerated forgetting and impaired recall but, thereafter, ALF patients show accelerated forgetting and impaired delayed recall. These delayed impairments may be more severe than those shown by hippocampal-amnesics...

The purpose of this study was to examine school nurses' management and collaboration with health-care providers (HCPs) for student-athletes following a concussion. Secondary school nurses accessed an online survey titled the Beliefs, Attitudes, and Knowledge of Pediatric Athletes with Concussions (access rate = 15.6%; n = 1,246/8,000). Approximately 40% of schools where nurses were employed administered baseline and postinjury concussion assessments. No significant differences were found between employment model (single vs...

Alzheimer's disease is rapidly becoming an endemic for people over the age of 65. A vital path towards reversing this ominous trend is the building of reliable diagnostic devices for definite and early diagnoses in lieu of the longitudinal, usually inconclusive and non-generalize-able methods currently in use. In this article, we present a survey of methods for mining pools of mass spectrometer saliva data in relation to diagnosing Alzheimer's disease. The computational methods provides new approaches for appropriately gleaning latent information from mass spectra data...

Findings of neurocognitive dysfunction in subjects at Clinical High Risk for Psychosis (CHR-P) have been controversial. This meta-analysis systematically examined studies of neurocognitive functions using the MATRICS Consensus Cognitive Battery (MCCB) in CHR-P. An independent literature search of both English and Chinese databases was conducted by two reviewers. Standardized mean difference (SMD) was calculated using a random effects model to evaluate the effect size of the meta-analytic results. Six case-control studies (n = 396) comparing neurocognitive functions between CHR-P subjects (n = 197) and healthy controls (n = 199) using the MCCB were identified; 4 (66...
