Junmin Liu, Chunxia Zhang, Jiangshe Zhang, Huirong Li, Yuelin Gao
BACKGROUND: Recently, sparse unmixing has been successfully applied to spectral mixture analysis of remotely sensed hyperspectral images. Based on the assumption that the observed image signatures can be expressed in the form of linear combinations of a number of pure spectral signatures known in advance, unmixing of each mixed pixel in the scene is to find an optimal subset of signatures in a very large spectral library, which is cast into the framework of sparse regression. However, traditional sparse regression models, such as collaborative sparse regression, ignore the intrinsic geometric structure in the hyperspectral data...

Gro Jordalen, Pierre-Nicolas Lemyre, Natalie Durand-Bush
Quality of motivation, self-control competencies, as well as past performance experience influence sport participation outcomes in developing athletes. Studies have shown that junior athletes high in self-determined motivation are less prone to experience burnout, while self-control competencies help developing athletes to be conscious and deliberate in their self-regulatory efforts toward elite sport performances and avoid negative sport participation outcomes. Combining the self-determination theory framework and psychosocial theories of self-regulation, the aim of this cross-sectional study was to examine how various types of motivation and self-control competencies together are associated with the development of burnout symptoms in junior athletes...

Objective: Temperament and mental illness have been linked to the same systems of behavioral regulation. A temperament model, carefully structured to respond to subtle differences within systems of behavior regulation, should exhibit distinct temperament patterns in the presence of mental illness. Previous comparisons of temperament profiles in mental disorders used mostly emotionality-related traits. In contrast, the Functional Ensemble of Temperament (FET) model differentiates not only between emotionality traits, but also between traits related to physical, verbal, and mental aspects of behavior and maps 12 functional aspects of behavior to temperament traits as well as to symptoms of mental illnesses...

The mechanisms by which childhood socioeconomic status (CSES) affects adult mental health, general health, and well-being are not clear. Moreover, the analytical assumptions employed when assessing mediation in social and psychiatric epidemiology are rarely explained. The aim of this paper was to explain the intermediate confounding assumption, and to quantify differential recall bias in the association between CSES, childhood abuse, and mental health (SCL-10), general health (EQ-5D), and subjective well-being (SWLS)...

BACKGROUND: In patients with COPD, self-management skills are important to reduce the impact of exacerbations. However, both detection and adequate response to exacerbations appear to be difficult for some patients. Little is known about the underlying process of exacerbation-related self-management. Therefore, the objective of this study was to identify and explain the underlying process of exacerbation-related self-management behavior. METHODS: A qualitative study using semi-structured in-depth interviews was performed according to the grounded theory approach, following a cyclic process in which data collection and data analysis alternated...

Providing personalised optimal mechanical ventilation for patients with acute or chronic respiratory failure is still a challenge within a clinical setting for each case anew. In this article, we integrate electrical impedance tomography (EIT) monitoring into a powerful patient-specific computational lung model to create an approach for personalising protective ventilatory treatment. The underlying computational lung model is able to predict global quantities e.g., tracheal flow and tidal volume, as well as local tissue aeration and strains for any ventilation manoeuvre...

Virtually all humans are colonized with Candida albicans However, in immunocompromised individuals this benign commensal organism becomes a serious, life-threatening pathogen. Here, we describe and analyze the regulatory networks that modulate innate responses in the host niches. We identified Zcf15 and Zcf29, two Zinc Cluster transcription Factors (ZCF) that are required for C. albicans virulence. Previous sequence analysis of clinical C. albicans isolates from immunocompromised patients indicates that both ZCF genes diverged during clonal evolution...

The presence of arsenic in groundwater has become a global concern due to the health risks from drinking water with elevated concentrations. The Water Framework Directive (WFD) of the European Union calls for drinking water risk assessment for member states. The present study amalgamates readily available national and sub-national scale datasets on arsenic in groundwater in the Republic of Ireland. However, due to the presence of high levels of left censoring (i.e. arsenic values below an analytical detection limit) and changes in detection limits over time, the application of conventional statistical methods would inhibit the generation of meaningful results...

OBJECTIVE: The objective of the study was to identify factors associated with human papilloma virus (HPV) vaccine acceptability in parents of adolescent boys. This information is critical to the development of approaches to optimise HPV vaccine uptake among this population group. METHODS: We performed a systematic search of the literature in addressing factors influencing parental attitudes to and beliefs about HPV vaccine and its acceptability for use. The findings were organised within the framework of the Health Belief Model (HBM) and summarised using a semi quantitative method...

BACKGROUND: Organ transplantation is often the only treatment for end-stage organ failure and is considered to be a cost-effective intervention with high impact on the health and quality of life of patients with chronic illnesses. Algeria has low rates of organ donation and transplantation, and health system coverage is not sufficient for the large number of patients awaiting this type of treatment. Physicians' perspectives about the health system are essential to understanding the obstacles present in the development of transplant services...

BACKGROUND: This research analyzes teleconsultation from both a mechanistic and complex adaptive system (CAS) dominant logic in order to further understand the influence of dominant logic on utilization rates of teleconsultation projects. In both dominant logics, the objective of teleconsultation projects is to increase access to and quality of healthcare delivery in a cost efficient manner. A mechanistic dominant logic perceives teleconsultation as closely resembling the traditional service delivery model, while a CAS dominant logic focuses on the system's emergent behavior of learning resulting from the relationships and interactions of participating healthcare providers...

Cervical spinal cord injury (cSCI) occurs in over half of all cases of traumatic SCI, yet we lack therapies that can generate significant functional recovery in these patients. The development of animal models of cSCI will aid in the pre-clinical assessment of therapies and in understanding basic pathophysiological mechanisms. Here we describe a clinically relevant model of cervical contusion-compression injury in the mouse. Using a modified aneurism clip we generated a bilateral, incomplete injury that mimics contusion-compression injuries most commonly seen in humans...

An important goal of censored quantile regression is to provide reliable predictions of survival quantiles, which are often reported in practice to offer robust and comprehensive biomedical summaries. However, formal methods for evaluating and comparing working quantile regression models in terms of their performance in predicting survival quantiles have been lacking, especially when the working models are subject to model mis-specification. In this article, we proposes a sensible and rigorous framework to fill in this gap...

When a water distribution system (WDS) is contaminated, short-term inhalation exposures to airborne contaminants could occur as the result of domestic water use. The most important domestic sources of such exposures are likely to be showering and the use of aerosol-producing humidifiers, i.e., ultrasonic and impeller (cool-mist) units. A framework is presented for assessing the potential effects of short-term, system-wide inhalation exposures that could result from such activities during a contamination event...

BACKGROUND: As test and treat rolls out, effective interventions are needed to address the determinants of outcomes across the HIV treatment continuum and ensure that people infected with HIV are promptly tested, initiate treatment early, adhere to treatment, and are virally suppressed. Communication approaches offer viable options for promoting relevant behaviors across the continuum. CONCEPTUAL FRAMEWORK: This article introduces a conceptual framework, which can guide the development of effective health communication interventions and activities that aim to impact behaviors across the HIV treatment continuum in low- and medium-income countries...

U.S. Latino farmworkers face multiple potential stressors. Research on the mental health status of this U.S. Latino subgroup has suggested high prevalence of stress, anxiety, and depressive symptoms when compared to other groups. Latina farmworkers may be at greater risk than their male counterparts for poor mental health because they confront many of the same stressors but may experience additional difficulties including domestic violence, taking on new roles and responsibilities on top of traditional ones, and being expected to maintain the health and integrity of their families at the expense of their own needs...

Perceptions about illnesses may influence self-care and preventive health behaviours. Illness perceptions of the Zika virus (ZIKV) infection were investigated under the framework of the Self-Regulation Model of Illness. Illness perception differences between ZIKV and dengue fever were also examined. Lastly, associations between illness perceptions of ZIKV with mosquito prevention practices were studied. Samples were drawn from landline telephone numbers using computer-assisted telephone interviewing in Malaysia...

Adolescent pregnancy has been typically linked to a range of adverse outcomes for mother and child. In Australia, Aboriginal and Torres Strait Islander women have a higher proportion of adolescent births compared with other adolescent Australian women, and are at greater risk of poorer psychosocial and clinical outcomes if they are not well supported during pregnancy and beyond. Drawing on existing literature and consultations with young Aboriginal women and health professionals supporting pregnant Aboriginal women in Western Australia, this paper discusses the importance of creating models of antenatal care using a "social determinants of health" framework...

OBJECTIVE: The common-sense model (Leventhal, Meyer, & Nerenz, 1980) outlines how illness representations are important for understanding adjustment to health threats. However, psychological processes giving rise to these representations are little understood. To address this, an associative-learning framework was used to model low-level process mechanics of illness representation and coping-related decision making. METHOD: Associative learning was modeled within a connectionist network simulation...

We present a flexible structural equation modeling (SEM) framework for the regression-based decomposition of rank-dependent indicators of socioeconomic inequality of health and compare it with simple ordinary least squares (OLS) regression. The SEM framework forms the basis for a proper use of the most prominent one- and two-dimensional decompositions and provides an argument for using the bivariate multiple regression model for two-dimensional decomposition. Within the SEM framework, the two-dimensional decomposition integrates the feedback mechanism between health and socioeconomic status and allows for different sets of determinants of these variables...
