Multi Attribute Decision Making

A unique set of cognitive and computational challenges arise in large-scale decision making, in relation to trade-off processing and design space exploration. While several multi-attribute decision making methods exist in the current design literature, many are insufficient or not fully explored for many-attribute decision problems of six or more attributes. To address this scaling in complexity, the methodology presented in this paper strategically elicits preferences over iterative attribute subsets while leveraging principles of the Hypothetical Equivalents and Inequivalents Method (HEIM). A case study demonstrates the effectiveness of the approach in the construction of a systematic representation of preferences and the convergence to a single ‘best’ alternative.

Large-scale crowd evacuation is an important measure guaranteeing the safety of disaster-stricken victims in typhoon relief activities. Decision-making related to antityphoon crowd evacuation must take full consideration of the destructive effect of typhoons and their secondary disasters, time urgency, and resource limitation. To give full play to limited vehicle resources, the influence of a typhoon and its secondary disasters on antityphoon evacuation are mainly manifested during the execution of evacuation tasks in this article. The shortest time spent in completing all evacuation tasks was taken as the objective. Then, a vehicle route selection model for two-phase large-scale antityphoon crowd evacuation was built under an uncertain environment, and a matrix encoding–based genetic algorithm was designed to solve the model. Under the background of Super Typhoon Meranti in 2016, the model and algorithm were applied to crowd evacuation in a typhoon in Xiamen for a simulated analysis. Results indicate that in typhoon relief activities, emergency decision makers can use the proposed method to acquire a scientific and reasonable route selection scheme for antityphoon crowd evacuation according to related typhoon disaster data.

Analysis of Ship's Safety Improvement in Confined Waters with use of the Decision Support System Based on Expert ManoeuvresThe paper presents analysis of possible ship's safety improvement in confined waters with the use of an expert system for navigator's decision support, constructed on the grounds of the knowledge base of gathered manoeuvres for a given type of ship, loading and hydrometeorological condition. The system generates results of encountered decision problems in the form of information about proposed adjustments of main engine, helm and tugs controls and future trajectory presented by means of panoramic graphic interface equivalent to vector large scale ENC and text interface of commands.

Progress towards Healthy Ageing in Europe: to promote active healthy lifestyles in 45-68 year olds through workplace, rather than traditional health-related settings

Purpose – Progress towards Healthy Ageing in Europe has been a two-year European funded project led by Suffolk County Council Public Health and involving five European Union (EU) member nations. The purpose of this paper is to share the learning from the project as it relates to early preventative activity to promote healthy active ageing. The population of interest are those people in the mid-life age group of 45-68 years accessed via the workplace. Design/methodology/approach – Qualitative research applying an online Health Manager tool and focus group discussions. Transnational work to learn from other EU countries about approaches to promote healthy active ageing. Findings – A comprehensive account of all project findings is available via the following web site: www.progresshealthyageing.eu This paper outlines the findings from the UK regional activity of the application of an online Health Manager™ tool to employees from Suffolk in the 45-68 year age group. Research limitations/implications – The research limitations related to smaller cohorts (ca. 1,000 participants) as opposed to large-scale surveys. The phenomenon of the “healthy worker effect” (Shah, 2009), may be a limitation as the population of interest in this age group were mainly employed and in paid employment. The healthy worker effect implies that those who are employed are already “healthier” due to being employed. The further limitation of the timescale for the intervention and project funding as a resource limitation precludes longer term follow-up and evidence collection to find out if behaviour change in participants has been sustained over time. Social implications – The findings of the EU Project have contributed towards the Europe 2020 Strategy. Locally the findings from the project have supported Suffolk County Council's ambition to be the most active county in England. The findings have added momentum to local workplace health initiatives by providing a focus for the needs of the older workforce. Learning from the Project has also informed development of the Suffolk Workplace Challenge. Originality/value – This paper provides a review on a European project, Progress towards Healthy Ageing in Europe.

Boechera Stricta

Investment in current reproduction can reduce future fitness by depleting resources needed for maintenance, particularly under environmental stress. These trade-offs influence life-history evolution. We tested whether climate change alters the future-fitness costs of current reproduction in a large-scale field experiment of Boechera stricta (Brassicaceae). Over 6 years, we simulated climate change along an elevational gradient in the Rocky Mountains through snow removal, which accelerates snowmelt and reduces soil water availability. Costs of reproduction were greatest in arid, lower elevations, where high initial reproductive effort depressed future fitness. At mid-elevations, initial reproduction augmented subsequent fitness in benign conditions, but pronounced costs emerged under snow removal. At high elevation, snow removal dampened costs of reproduction by prolonging the growing season. In most scenarios, failed reproduction in response to resource limitation depressed lifetime fecundity. Indeed, fruit abortion only benefited high-fitness individuals under benign conditions. We propose that climate change could shift life-history trade-offs in an environment-dependent fashion, possibly favouring early reproduction and short lifespans in stressful conditions.

Period Comet

AbstractUnusual short-period comet 29P/Schwassmann-Wachmann 1 inspired many observers to explain its unpredictable outbursts. In this paper large scale structures and features from the inner part of the coma in time periods around outbursts are studied. CCD images were taken at Whipple Observatory, Mt. Hopkins, in 1989 and at Astronomical Observatory, Modra, from 1995 to 1998. Photographic plates of the comet were taken at Harvard College Observatory, Oak Ridge, from 1974 to 1982. The latter were digitized at first to apply the same techniques of image processing for optimizing the visibility of features in the coma during outbursts. Outbursts and coma structures show various shapes.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.
