a longitudinal twin study of the direction of effects between psychopathic personality and antisocial behaviour
Journal of Child Psychology and Psychiatry, 2010Co-Authors: Mats Forsman, Paul Lichtenstein, Henrik Andershed, Henrik LarssonAbstract:Background: Antisocial behaviour may partly develop as a consequence of psychopathic personality. However, neither the direction of effects nor the aetiology of the association has previously been clarified. The aim in this study was to investigate the direction of effects between psychopathic personality and antisocial behaviour, and to investigate the genetic and Environmental Contribution to this association. Method: Twins (n = 2,255) in the Swedish Twin Study of Child and Adolescent Development were prospectively followed from adolescence to adulthood. We used a longitudinal cross-lagged twin model to study the associations between psychopathic personality and antisocial behaviour. Results: Psychopathic personality in mid-adolescence predicted antisocial behaviour in adulthood (p < .001), but not the other way around. However, bidirectional effects were found when a measure of persistent antisocial behaviour (from age 8–9 to age 16–17) was used. Psychopathic personality predicted both rule-breaking behaviour (p < .001) and aggressive behaviour (p < .01). Genetic factors were of importance in mediating the longitudinal associations between psychopathic personality and antisocial behaviour. Conclusions: This study provides evidence that genetically influenced psychopathic personality is a robust predictor of adult antisocial behaviour, but also that persistent antisocial behaviour has an impact on adult psychopathic personality via genetic effects. Keywords: Antisocial behaviour, psychopathic personality, longitudinal, twins.

development of a new framework for non monetary accounting on ecosystem services valuation
Ecosystem services, 2018Co-Authors: Qing Yang, Gengyuan Liu, Marco Casazza, Elliott Campbell, Biagio F Giannetti, Mark T BrownAbstract:Abstract To appropriately support green development practices, there is an urgent need to improve Ecosystem Services Valuation (ESV) accounting approaches. This paper establishes a non-monetary accounting framework for ESV, which classifies the ES into direct services (directly related to the stock and flow), indirect services (through the functioning of ecosystem processes that produce the direct services) and existence services (cultural services and global benefit). New framework tries to (1) construct system emergy flow diagram and merging calculation method to avoid double counting; (2) propose new methods for biodiversity and climate regulation; and (3) bridge the non-monetary and economic values. Taking the forest ecosystem in Jing-Jin-Ji urban agglomeration as a case, this study made a detailed calculations of 9 ecosystem services and compared the Em¥ with economic values based on Emergy Money Ratio. The results show that emergy can be used to record Environmental debt and establish a balance sheet to state the economic conditions and the Environmental Contribution to economic development. However, emergy is not an alternative method to the economic assessment, but a complementary and systemic approach to highlight the donor-side value of ES. The new framework is needed to realize the return of wealth including all “stakeholders” of nature.

emergy evaluations and Environmental loading of electricity production systems
Journal of Cleaner Production, 2002Co-Authors: Mark T Brown, Sergio UlgiatiAbstract:Abstract Six electricity production systems are evaluated using energy and emergy (Environmental Accounting. Emergy and Environmental Decision Making. New York:Wiley, 1996. 370pp.) accounting techniques, in order to rank their relative thermodynamic and Environmental efficiencies. The output/input energy ratio as well as the emergy-based emergy yield ratio (EYR) and Environmental loading ratio (ELR) have been jointly used to explore and compare system performances. Generation of CO2 has also been accounted for in order to compare renewable and nonrenewable energy sources. The production systems include both plants using nonrenewable energy sources (natural gas, oil, and coal thermal plants) and the so-called renewable energy sources (geothermal, hydroelectric, and wind plants). A method for evaluating the Environmental Contribution to electric production is shown to provide important information that can be used to support the Environmentally sound public policy. Renewable power plants were characterized by high energy return on investment, while fossil fueled plants exhibited average energy efficiency in the 25–36% range. EYR varied from a high of 7.6/1 for hydroelectric generation to about 4.2/1 for the oil thermal plant. The renewable energy plants required the highest Environmental inputs per unit of output while fossil fuel plants required relatively small Environmental inputs for cooling and to support fuel combustion. Environmental loading was highest with thermal plants. Using an emergy index of sustainability, it is quantitatively shown how renewable energy source plants like wind, hydroelectric, and geothermal had higher sustainability compared to thermal plants.
