While homeownership has been linked to positive health outcomes there is limited evidence regarding the conditions under which it may be health protective. We present a conceptual model linking homeownership to health, highlighting key potential pathways. Using the Detroit Metropolitan Area as a case study, and data from the American Community Survey (2009-2013; 5-years estimates) and Michigan Department of Community Health, we tested the following questions: (1) Is neighborhood percentage non-Hispanic Black (NHB) associated with homeownership? (2) Is neighborhood percentage NHB associated with health? (3) Is the association between percentage NHB and health mediated by homeownership? (4) Does neighborhood housing value modify associations between percentage NHB and health, or between homeownership and health? Percentage NHB was associated with homeownership and health outcomes; Associations between percentage NHB and mortality, but not disability, were partially mediated by neighborhood homeownership...

Human trafficking is a global problem; more than half of all victims are children. In the United States (US), at-risk youth continue to attend school. School nurses are on the frontlines, presenting a window of opportunity to identify and prevent exploitation. Available papers targeting school nurses report that school nurses may lack awareness of commercial sexual exploitation and may have attitudes and misperceptions about behaviors of school children at risk. This is a theoretical paper applying the Peace and Power Conceptual Model to understand the role of school nurses in commercial sexual exploitation of children...

The purpose of this essay is to discuss who participants should be in population health nursing research within the context of the Conceptual Model of Nursing and Population Health. The emphasis is on recruitment of research participants who constitute populations rather than samples drawn from populations and the challenges of obtaining informed consent from populations.

Spatial patterns of soil erosion and deposition can be inferred from differences in ground elevation mapped at appropriate time increments. Such changes in elevation are related to changes in near-surface soil carbonate (CaCO3) profiles. The objective is to describe a simple conceptual model and detailed protocol for repeatable field and laboratory measurements of these quantities. Here, accurate elevation is measured using a ground-based differential global positioning system (GPS); other data acquisition methods could be applied to the same basic method...

OBJECTIVE: Prescription opioid and benzodiazepine drug use, which has risen significantly, can affect worker health. Exploration of the scientific literature assessed (1) interrelationships of such drug use, occupational risk factors, and illness and injury, and (2) occupational and personal risk factor combinations that can affect their use. METHODS: The scientific literature from 2000 to 2015 was searched to determine any interrelationships. RESULTS: Evidence for eight conceptual models emerged based on the search yield of 133 articles...

Aromatic amine dehydrogenase (AADH) and related enzymes are at the heart of debates on the roles of quantum tunnelling and protein dynamics in catalysis. The reaction of tryptamine in AADH involves significant quantum tunnelling in the rate-limiting proton transfer step, shown e.g. by large H/D primary kinetic isotope effects (KIEs), with unusual temperature dependence. We apply correlated ab initio combined quantum mechanics/molecular mechanics (QM/MM) methods, at levels up to local coupled cluster theory (LCCSD(T)/(aug)-cc-pVTZ), to calculate accurate potential energy surfaces for this reaction, which are necessary for quantitative analysis of tunnelling contributions and reaction dynamics...

Infectious animal diseases can spill across farm boundaries, so effective management requires coordinated responses. Costs and benefits from the management of infectious diseases are such that those who make the decisions have weak incentives to act, the levels of goods and services produced from animal agriculture are probably smaller than is socially optimal and resources are likely wasted. This work provides an overview of the existing literature on conceptual economic models in animal disease management, paying particular attention to inadequate incentives to make the required biosecurity efforts...

Racial/ethnic minorities experience a disproportionate risk of both suboptimal sleep and obesity, and the relationship between sleep and obesity may differ by race/ethnicity for modifiable and non-modifiable reasons. Because many people of color have historically lived and continue to largely live in disadvantaged, obesogenic physical and social environments, these greater adverse exposures likely negatively affect sleep, resulting in physiological dysregulation. Physiological dysregulation may, in turn, lead to increased obesity risk and subsequent health consequences, which are likely more influential than potential genetic differences in race, a social construct...

The convergence of medical treatment that can extend life with written medical orders that make it possible to refuse such treatment brings the differential dynamics of contemporary end-of-life decision-making into sharp focus. Communication between families and clinicians can be confusing, uncertain and pressured when death is imminent. These situations create distress that ultimately influences the end-of-life experience for people who are dying and those who care for them. This paper presents the analysis of the decisional dynamics that emerge from the intersection of the patient-family-provider awareness that death is near with the presence or absence of documentation of expressed wishes for end-of-life care...

The active plume at Enceladus' south pole makes the indirect sampling of its global ocean possible. The partially resolved chemistry of the plume, which points to conditions that are seemingly compatible with life, has made orbital sampling missions a priority. We present a conceptual model of energy flux, hydrothermal H2 production, and both abiotic and biotic production of amino acids. Based on the energy flux observed at the south pole and the inferred internal hydrothermal activity, we estimate an H2 production of 0...

The aim of this study was to generate a patient-centered conceptual model of the impact of living with autism spectrum disorder, which can be used to support the selection of outcome measures for clinical trials. Following an initial literature review to identify preliminary concepts and inform an interview guide, in-depth face-to-face interviews were conducted with adolescents and adults with autism spectrum disorder (IQ ⩾ 70) (n = 10), as well as parents of children, adolescents, and adults with autism spectrum disorder (IQ ⩾ 70) (n = 26)...

This essay, written to celebrate the 30th anniversary of Nursing Science Quarterly, focuses on the distinctions between the discipline of nursology and the trade of medicine. The distinctions are drawn from content found in nursing conceptual models and from literature about the elusive content of the so-called "medical model."

REVIEW
Brooke Sanderson, Margo Brewer
OBJECTIVES: Resilience has been identified as a key capability to thrive in the complex changing work environment of the 21st century. Therefore, the aim of this scoping review was to investigate how resilience is understood in the context of pre-qualifying health education, if there is a need to build student resilience, and what approaches to enhancing student resilience are described in the literature. DESIGN AND DATA SOURCES: Arksey and O'Malley's (2005) literature scoping review design was adopted as it enables researchers to review, summarise and analyse the literature on a given topic...

Stereotyped motor behavior manifests as rhythmic, repetitive movements. It is common in several neurologic and psychiatric disorders where it is considered maladaptive. However, it also occurs early in typical development where it serves an adaptive function in the development of complex, controlled motor behavior. Currently, no framework accounts for both adaptive and maladaptive forms of motor stereotypy. We propose a conceptual model that implicates sensorimotor mechanisms in the phenomenology of adaptive and maladaptive stereotypy...

ISSUE: There is limited information and consensus on the future of clinical education. The Delphi technique was selected to identify agreement among Association of Schools of Allied Health Professions' (ASAHP) allied health deans on the future (2018-2023) of allied health (AH) clinical education. METHODS: Sixty-one AH deans, 54.9% (61 of 111) of the ASAHP membership, expressed opinions about clinical education through a three-round Delphi study. In conjunction with a conceptual model, four futuristic scenarios were used to encourage deans' feedback on the key factors impacting the future of clinical education...

EDITORIAL
Marlis Buchmann, Annekatrin Steinhoff
Conceptualizing adolescent development within a life course framework that links the perspectives on social inequality and early life course transitions has largely been absent from previous research. Such a conceptual model is needed, however, in order to understand how the individual development of agentic capacities and the opportunities and constraints inherent in the social contexts of growing up interact and jointly affect young people's trajectories across the adolescent life stage. We present the corner stones of the conceptual "trident" of social inequality, life course transitions, and adolescent development and identify three major themes the eleven contributions to this special issue address within this conceptual framework: social and individual prerequisites and consequences of coping with life course transitions; intergenerational transmission belts of social inequality; socialization of agency in and outside the family home...

Research on sedentary behavior and adiposity in youth dates back to the 1980s. Sedentary behaviors, usually screen time, can be associated with adiposity. While the association is usually small but significant, the field is complex, and results are dependent on what sedentary behaviors are assessed, and may be mediated and moderated by other behaviors.

Timothy W Smith, Brian R W Baucom
Being married or involved in a similar intimate relationship is associated with reduced risk of coronary heart disease (CHD). However, the quality of these relationships matters, as strain and disruption are associated with increased risk. These effects are typically studied separately from well-established psychosocial factors for CHD that are aspects of personality and emotional adjustment, even though discord and disruption in intimate relationships are related to these same individual characteristics. Thus, research to date tends to parse correlated risks, often taking a piecemeal approach by focusing on intimate relationships without considering aspects of personality and emotional adjustment that contribute to risk and protection, or focusing on individual-level risks while largely ignoring closely related health-relevant relationships...

It is well known that oil droplets in or on water exhibit spontaneous movement induced by surfactants, and this self-propulsion is regarded as an important factor in droplet-based models for a living cell. We report here an oil-droplet system spontaneously producing amino acid-based surfactants, which are then utilized for the droplets' self-propulsion. Thus this system is an active system capable of producing the fuel for the propulsion by itself, which can be used as a conceptual model for cell metabolism...
