Conceptual model

Emma Monte, Manuel Rosa Garrido, Thomas M Vondriska, Jessica Wang
The past two decades have witnessed a rapid evolution in our ability to measure RNA and protein from biological systems. As a result, new principles have arisen regarding how information is processed in cells, how decisions are made, and the role of networks in biology. This essay examines this technological evolution, reviewing (and critiquing) the conceptual framework that has emerged to explain how RNA and protein networks control cellular function. We identify how future investigations into transcriptomes, proteomes, and other cellular networks will enable development of more robust, quantitative models of cellular behavior whilst also providing new avenues to use knowledge of biological networks to improve human health...

This is a conceptual theoretical study to reflect upon disability and some basic concepts that are involved in its profiling. The scope of the article is to broaden the outlook upon disability removing it from a description that reduces it to an ailment. For this purpose, we situated the Disability Studies historically presenting the Medical and Social Models of Disability and problematized the concepts of autonomy and normality. These concepts and their correlated aspects - independence, functionality and the norm - are used as a tacit touchstone to differentiate some bodily variations that are identified as different lifestyles from others that are often called disabilities...

This article derives from a study conducted on the validation of the Brazilian Functionality Index (IF-BrA) applied to the granting of retirement benefits to disabled persons. The retirement of persons with disabilities is regulated by Complementary Law 142 of May 8, 2013. The aim is to discuss how the individuals involved in application of the instrument perceive the concept of disability and the possible implications for ensuring the right to retirement. Eleven agencies of the National Social Security Institute (INSS) were visited and 16 physicians, 16 social workers and 40 persons with disabilities were interviewed...

In contrast to historical conceptualizations that framed psychological disorders as distinct, categorical conditions, it is now widely understood that co- and multi-morbidities between disorders are extensive. As a result, there has been a call to better understand the dimensional liabilities that are common to and influence the development of multiple psychopathologies, as supported and exemplified by the National Institutes of Mental Health (NIMH) Research Domain Criteria (RDoC) framework. We use a latent variable SEM approach to examine the degree to which working memory deficits represent a cognitive liability associated with the development of common and discrete dimensions of psychopathology...

OBJECTIVES: The availability of internet-connected mobile, wearable and ambient consumer technologies, direct-to-consumer e-services and peer-to-peer social media sites far outstrips evidence about the efficiency, effectiveness and efficacy of using them in healthcare applications. The aim of this paper is to describe one approach to build a program of health informatics research, so as to generate rich and robust evidence about health data and information processing in self-quantification and associated healthcare and health outcomes...

OBJECTIVE: To know the opinions and satisfaction of nurses with the use of INICIARE, an instrument developed for assessment of nursing care needs in hospitalized patients. INICIARE is based on Virginia Henderson's conceptual model, and built up with indicators of Nursing Outcomes Classification (NOC) taxonomy. METHOD: Exploratory qualitative study, using focus group technique for data collection. The sessions were recorded until saturation of information. A content analysis of syntactic, semantic and pragmatic levels of transcripts was performed...

Concept mapping was developed in the 1980s as a unique integration of qualitative (group process, brainstorming, unstructured sorting, interpretation) and quantitative (multidimensional scaling, hierarchical cluster analysis) methods designed to enable a group of people to articulate and depict graphically a coherent conceptual framework or model of any topic or issue of interest. This introduction provides the basic definition and description of the methodology for the newcomer and describes the steps typically followed in its most standard canonical form (preparation, generation, structuring, representation, interpretation and utilization)...

Several methods exist to compute the likelihood ratio LR(M, g) evaluating the possible contribution of a person of interest with genotype g to a mixed trace M. In this paper we generalize this LR to a likelihood ratio LR(M1, M2) involving two possibly mixed traces M1 and M2, where the question is whether there is a donor in common to both traces. In case one of the traces is in fact a single genotype, then this likelihood ratio reduces to the usual LR(M, g). We explain how our method conceptually is a logical consequence of the fact that LR calculations of the form LR(M, g) can be equivalently regarded as a probabilistic deconvolution of the mixture...

The transfer of organic material from one coastal environment to another can increase production in recipient habitats in a process known as spatial subsidy. Microorganisms drive the generation, transformation, and uptake of organic material in shallow coastal environments, but their significance in connecting coastal habitats through spatial subsidies has received limited attention. We address this by presenting a conceptual model of coastal connectivity that focuses on the flow of microbially mediated organic material in key coastal habitats...

Recent empirical and conceptual papers have highlighted the potential for metabolism to act as a proximate mechanism for behavior that could explain animal personality (consistency over time). Under this hypothesis, individuals with consistently high levels of behavioral activity should also have high resting metabolic rate (RMR) as it can reflect capacity to process food and generate energy. We tested for the predicted positive covariance between RMR and three behaviors that differ in energy demands in 30 male guppies, using multivariate mixed models; we repeatedly measured their activity (10 times each), courtship displays (nine times), voracity (10 times), and metabolism (four-times)...

BACKGROUND: Posttraumatic growth (PTG) was conceptualized as consisting of changes in three broad dimensions; Self, interpersonal relationships, and philosophy of life. The aim of this study is to analyze the factor structure of the Posttraumatic Growth Inventory (PTGI) in a sample of parents whose children had survived a critical hospitalization in order to consider the structural validity of the PTGI scores for this population and to report our understanding of PTG as a construct. METHODS: 143 parents completed the PTGI 6 months after their child’s discharge from pediatric intensive care...

BACKGROUND: Several RCT studies have aimed to reduce either musculoskeletal disorders, sickness presenteeism, sickness absenteeism or a combination of these among females with high physical work demands. These studies have provided evidence that workplace health promotion (WHP) interventions are effective, but long-term effects are still uncertain. These studies either lack to succeed in maintaining intervention effects or lack to document if effects are maintained past a one-year period...

Personality disorders (PDs) are inherently associated with deficits in relating to other people. Previous research has shown consistent negative associations between categorical PD symptoms and relationship satisfaction. The present studies extend on these findings by examining the role of maladaptive traits in a number of ways. Self- and partner-reported maladaptive traits of both partners are included. Moreover, the present studies add a couple-centered approach by investigating the effects of actual similarity, perceptual similarity, and perceptual accuracy of the maladaptive trait profile on relationship satisfaction...

Volumetric properties of proteins bear directly on their biological functions in hyperbaric environments and are useful in general as a biophysical probe. To gain insight into conformation-dependent protein volume, we developed an implicit-solvent atomic chain model that transparently embodies two physical origins of volume. First, a fundamental geometric term capturing the van der Waals volume of the protein and the particulate, finite-size nature of the water molecules, modeled together by the volume encased by the protein's molecular surface...

When thinking about priority setting in access to healthcare resources, decision-making requires that cost-effectiveness is balanced against medical ethics. The burden of disease has emerged as an important approach to the assessment of health needs for political decision-making. However, the disability adjusted life years approach hides conceptual and methodological issues regarding the claims and value of disabled people. In this article, we discuss ethical issues that are raised as a consequence of the introduction of evidence-based health policy, such as economic evidence, in establishing resource allocation priorities...

BACKGROUND AND OBJECTIVE: To clarify mechanisms of genetic regulation of human aging and longevity traits, a number of genome-wide association studies (GWAS) of these traits have been performed. However, the results of these analyses did not meet expectations of the researchers. Most detected genetic associations have not reached a genome-wide level of statistical significance, and suffered from the lack of replication in the studies of independent populations. The reasons for slow progress in this research area include low efficiency of statistical methods used in data analyses, genetic heterogeneity of aging and longevity related traits, possibility of pleiotropic (e...

Children who have experienced environmental adversity-such as abuse, neglect, or poverty-are more likely to develop physical and mental health problems, perform poorly at school, and have difficulties in social relationships than children who have not encountered adversity. What is less clear is how and why adverse early experiences exert such a profound influence on children's development. Identifying developmental processes that are disrupted by adverse early environments is the key to developing better intervention strategies for children who have experienced adversity...

Despite mentally disordered suspects being over-represented within the criminal justice system, there is a dearth of published literature that examines police officers' perceptions when interviewing this vulnerable group. This is concerning given that police officers are increasingly the first point of contact with these individuals. Using a Grounded Theory approach, this study examined 35 police officers' perceptions and experiences when interviewing mentally disordered suspects. Current safeguards, such as Appropriate Adults, and their experiences of any training they received were also explored...
