The most commonly used techniques for addressing each Emergency Department (ED) problem (overcrowding, prolonged waiting time, extended length of stay, excessive patient flow time, and high left-without-being-seen (LWBS) rates) were specified to provide healthcare managers and researchers with a useful framework for effectively solving these operational deficiencies. Finally, we identified the existing research tendencies and highlighted opportunities for future work. We implemented the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to undertake a review including scholarly articles published between April 1993 and October 2019. The selected papers were categorized considering the leading ED problems and publication year. Two hundred and three (203) papers distributed in 120 journals were found to meet the inclusion criteria. Furthermore, computer simulation and lean manufacturing were concluded to be the most prominent approaches for addressing the leading operational problems in EDs. In future interventions, ED administrators and researchers are widely advised to combine Operations Research (OR) methods, quality-based techniques, and data-driven approaches for upgrading the performance of EDs. On a different tack, more interventions are required for tackling overcrowding and high left-without-being-seen rates.

In recent years, environmental-oriented concepts of sustainable urban development have been actively developing, in particular, in the spheres of energy efficiency and resource conservation in the context of the theory of thrift, smart and environmentally-oriented creation. Four scientific concepts can be distinguished from a set of scientific theories and methodological approaches: industrial metabolism; control «on the pipe»; social and ecological metabolism, thrifty production. In particular, the concept of «lean manufacturing» has shown its effectiveness in practice in many countries in various industries. This concept is environmentally friendly, has a high potential for implementation, but is not sufficiently appreciated by domestic enterprises. Despite its widespread implementation and development, the lack of its implementation at domestic industrial enterprises is explained by the lack of adapted methods and tools for resource conservation management based on this concept. It explains the relevance of the study, which proposes a theoretical and methodological substantiation of the program for a phased transition to «lean manufacturing», which ensures an increase in the efficiency of enterprises in modern conditions, which will increase the sustainability of cities ultimately.

Abstract We identify the significance and typical requirements of developmental analyses of the microbiome-gut-brain (MGB) in parents, offspring, and parent-offspring relations, which have particular importance for neurobehavioral outcomes in mammalian species, including humans. We call for a focus on behavioral measures of social-emotional function. Methodological approaches to interpreting relations between the microbiota and behavior are discussed.

Whereas subjective well-being remains relatively stable across adulthood, emotional experiences show remarkable short-term variability, with younger and older adults differing in both amount and correlates. Repeatedly assessed affect data captures both the dynamics and stability as well as stabilization that may indicate emotion-regulatory processes. The article reviews (1) research approaches to intraindividual affect variability, (2) functional implications of affect variability, and (3) age differences in affect variability. Based on this review, we discuss how the broader literature on emotional aging can be better integrated with theories and concepts of intraindividual affect variability by using appropriate methodological approaches. Finally, we show how a better understanding of affect variability and its underlying processes could contribute to the long-term stabilization of well-being in old age.
