Modern challenges require new approaches to urban water management. One solution in the portfolio of potential strategies is the integration of distributed water infrastructure, practices, and technologies into existing systems. However, many practical barriers have prevented the widespread adoption of these systems in the US. The objective of this paper is to address these challenges by developing a conceptual model encompassing regulatory, financial, and governance components that can be used to incorporate new distributed water solutions into our current network...

For over 100 years it has been recognized that insect pests evolve resistance to chemical pesticides. More recently, managers have advocated restrained use of pesticides, crop rotation, the use of multiple pesticides, and pesticide-free sanctuaries as resistance management practices. Game theory provides a conceptual framework for combining the resistance strategies of the insects and the control strategies of the pest manager into a unified conceptual and modelling framework. Game theory can contrast an ecologically enlightened application of pesticides with an evolutionarily enlightened one...

BACKGROUND: Space travel is associated with continuous low dose rate exposure to high linear energy transfer (LET) radiation. Pathophysiological manifestations after low dose radiation exposure are strongly influenced by non-cytocidal radiation effects, including changes in the microbiome and host gene expression. Although the importance of the gut microbiome in the maintenance of human health is well established, little is known about the role of radiation in altering the microbiome during deep-space travel...

PURPOSE: Measurement invariance issues should be considered during test construction. In this paper, we provide a conceptual overview of measurement invariance and describe how the concept is implemented in several different statistical approaches. Typical applications look for invariance over things such as mode of administration (paper and pencil vs. computer based), language/translation, age, time, and gender, to cite just a few examples. To the extent that the relationships between items and constructs are stable/invariant, we can be more confident in score interpretations...

Current taxonomic systems are based on a descriptive and categorical approach where psychopathological symptoms and signs are caused by a hypothetical underlying mental disorder. In order to circumvent the limitations of classification systems, it is necessary to incorporate new conceptual and psychometric models that allow to understand, analyze and intervene in psychopathological phenomena from another perspective. The main goal was to present a new approach called network analysis for its application in the field of psychopathology...

BACKGROUND: Sense of coherence (SOC) is a psychosocial factor capable of influencing perception of health, improving one's ability to manage life. It is the central construct of salutogenesis. SOC allows for identification and mobilization of resources to effectively manage or solve problems, promoting health and quality of life. Using Wilson-Cleary's conceptual model we hypothesized that SOC might contribute to self-perception of dental aesthetics. The aim of this study was to investigate whether SOC levels were related to self-perception of dental aesthetics against assessed normative orthodontic treatment need among adolescents...

There is insufficient research examining the implementation of complex novel interventions within health care. This may be due to a lack of qualitative research providing subjective insights into these implementation processes. The authors investigate the advantages of applying behavior change theories to conceptualize qualitative data describing the processes of implementation of complex interventions. Breaking Free Online (BFO), a digital treatment intervention for substance misuse, is described as an example of a complex intervention...

A rigorous understanding of brain dynamics and function requires a conceptual bridge between multiple levels of organization, including neural spiking and network-level population activity. Mounting evidence suggests that neural networks of cerebral cortex operate at a critical regime, which is defined as a transition point between two phases of short lasting and chaotic activity. However, despite the fact that criticality brings about certain functional advantages for information processing, its supporting evidence is still far from conclusive, as it has been mostly based on power law scaling of size and durations of cascades of activity...

Depression, anxiety and other affective disorders are globally widespread and severely debilitating human brain diseases. Despite their high prevalence and mental health impact, affective pathogenesis is poorly understood, and often remains recurrent and resistant to treatment. The lack of efficient antidepressants and presently limited conceptual innovation necessitate novel approaches and new drug targets in the field of antidepressant therapy. Areas covered: Herein, the authors discuss the emerging role of neuro-immune interactions in affective pathogenesis, which can become useful targets for CNS drug discovery, including modulating neuroinflammatory pathways to alleviate affective pathogenesis...

Research on moral dilemma judgments has been fundamentally shaped by the distinction between utilitarianism and deontology. According to the principle of utilitarianism, the moral status of behavioral options depends on their consequences; the principle of deontology states that the moral status of behavioral options depends on their consistency with moral norms. To identify the processes underlying utilitarian and deontological judgments, researchers have investigated responses to moral dilemmas that pit one principle against the other (e...

Most recent models conceptualize working memory (WM) as a continuous resource, divided up according to task demands. When an increasing number of items need to be remembered, each item receives a smaller chunk of the memory resource. These models predict that the allocation of attention to high-priority WM items during the retention interval should be a zero-sum game: improvements in remembering cued items come at the expense of uncued items because resources are dynamically transferred from uncued to cued representations...

Memory research has long been one of the key areas of investigation for cognitive aging researchers but only in the last decade or so has categorization been used to understand age differences in cognition. Categorization tasks focus more heavily on the grouping and organization of items in memory, and often on the process of learning relationships through trial and error. Categorization studies allow researchers to more accurately characterize age differences in cognition: whether older adults show declines in the way in which they represent categories with simple rules or declines in representing categories by similarity to past examples...

Little is known about how rural-dwelling older adults anticipate and plan for future care needs. Using a mixed-method explanatory design, structural equation modeling ( n = 535) revealed significant associations between concerns about using services on preference for type of help; preference was associated with likelihood of using future services. Content analysis of interview data from 19 older adults who needed but were not receiving help revealed how they conceptualize their need for assistance and anticipated future care arrangements...

This paper presents five studies on the development and validation of a scale of intellectual humility. This scale captures cognitive, affective, behavioral, and motivational components of the construct that have been identified by various philosophers in their conceptual analyses of intellectual humility. We find that intellectual humility has four core dimensions: Open-mindedness (versus Arrogance), Intellectual Modesty (versus Vanity), Corrigibility (versus Fragility), and Engagement (versus Boredom). These dimensions display adequate self-informant agreement, and adequate convergent, divergent, and discriminant validity...

REVIEW

Exercise psychology has yet to produce intervention methods capable of increasing exercise and physical activity behavior in a sustainable manner. This situation is forcing a critical reevaluation of current conceptual models, especially the assumption that behavioral decisions are driven solely by the rational evaluation of information. Like other behavioral sciences, exercise psychology is transitioning to dual-process models that acknowledge the importance of non-reflective processes. Emerging evidence suggests that the pleasure or displeasure experienced during exercise may influence subsequent physical activity...

Andrew P Hill, Daniel J Madigan
The purpose of the current paper is to review research examining multidimensional perfectionism in sport, dance, and exercise. We start by providing a conceptual overview of perfectionism. We then describe three main approaches to examining perfectionism. These approaches are an independent effects approach, the tripartite model, and the 2×2 model of perfectionism. Alongside the description of each approach, research findings are summarized. We close the paper by explaining how the development of the 2×2 model has likely rendered the tripartite model obsolete...

Since mindfulness-based and acceptance-based practice models were first conceptualized and applied in sport in an attempt to enhance performance and overall well-being of athletes and performers, these state-of-the-art theoretical and practice models have substantially broadened our knowledge base and have been successfully incorporated into sport and performance practice domains worldwide. Evolving from a sound empirical foundation, mindfulness-based and acceptance-based models in sport psychology have accumulated a strong basic and applied empirical foundation...
