Risk Management and Behavioral Finance

Risk management is still dated in concept. It assumes a compliance approach. Current risk management approaches have failed in predicting both macro-economic and micro-economic setbacks and disasters. This is because financial metrics, the basis for modern risk metrics, are actually a lagging indicator of risk, not a leading indicator. Risk management needs a new paradigm which is based on leading indicators and which can therefore predict such problems. Behavioral finance provides the framework for a new paradigm for risk management

Growing Environmental Activists: Developing Environmental Agency and Engagement Through Children’s Fiction.

We explore how story has the potential to encourage environmental engagement and a sense of agency provided that critical discussion takes place. We illuminate this with reference to the philosophies of John Macmurray on personal agency and social relations; of John Dewey on the primacy of experience for philosophy; and of Paul Ricoeur on hermeneutics, dialogue, dialectics and narrative. We view the use of fiction for environmental understanding as hermeneutic, a form of conceptualising place which interprets experience and perception. The four writers for young people discussed are Ernest Thompson Seton, Kenneth Grahame, Michelle Paver and Philip Pullman. We develop the concept of critical dialogue, and link this to Crick's demand for active democratic citizenship. We illustrate the educational potential for environmental discussions based on literature leading to deeper understanding of place and environment, encouraging the belief in young people that they can be and become agents for change. We develop from Zimbardo the key concept of heroic resister to encourage young people to overcome peer pressure. We conclude with a call to develop a greater awareness of the potential of fiction for learning, and for writers to produce more focused stories engaging with environmental responsibility and activism

HAPEX-Sahel : a large-scale study of land-atmosphere interactions in the semi-arid tropics

The Hydrologic Atmospheric Pilot EXperiment in the Sahel (HAPEX-Sahel) was carried out in Niger, West Africa, during 1991 - 1992, with an intensive observation period (IOP) in August - October 1992. It aims at improving the parameterization of land surface atmosphere interactions at the Global Circulation Model (GCM) gridbox scale. The experiment combines remote sensing and ground based measurements with hydrological and meteorological modelling to develop aggregation techniques for use in large scale estimates of the hydrological and meteorological behaviour of large areas in the Sahel. The experimental strategy consisted of a period of intensive measurements during the transition period of the rainy to the dry season, backed up by a series of long term measurements in a 1° by 1° square in Niger. Three "supersites" were instrumented with a variety of hydrological and (micro) meteorological equipment to provide detailed information on the surface energy exchange at the local scale. Boundary layer measurements and aircraft measurements were used to provide information at scales of 100 - 500 km2. All relevant remote sensing images were obtained for this period. This programme of measurements is now being analyzed and an extensive modelling programme is under way to aggregate the information at all scales up to the GCM grid box scale. The experimental strategy and some preliminary results of the IOP are described

The performance of the jet trigger for the ATLAS detector during 2011 data taking

The performance of the jet trigger for the ATLAS detector at the LHC during the 2011 data taking period is described. During 2011 the LHC provided proton–proton collisions with a centre-of-mass energy of 7 TeV and heavy ion collisions with a 2.76 TeV per nucleon–nucleon collision energy. The ATLAS trigger is a three level system designed to reduce the rate of events from the 40 MHz nominal maximum bunch crossing rate to the approximate 400 Hz which can be written to offline storage. The ATLAS jet trigger is the primary means for the online selection of events containing jets. Events are accepted by the trigger if they contain one or more jets above some transverse energy threshold. During 2011 data taking the jet trigger was fully efficient for jets with transverse energy above 25 GeV for triggers seeded randomly at Level 1. For triggers which require a jet to be identified at each of the three trigger levels, full efficiency is reached for offline jets with transverse energy above 60 GeV. Jets reconstructed in the final trigger level and corresponding to offline jets with transverse energy greater than 60 GeV, are reconstructed with a resolution in transverse energy with respect to offline jets, of better than 4 % in the central region and better than 2.5 % in the forward direction

Search for long-lived neutral particles in pp collisions at s√=13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter

This paper describes a search for pairs of neutral, long-lived particles decaying in the ATLAS calorimeter. Long-lived particles occur in many extensions to the Standard Model and may elude searches for new promptly decaying particles. The analysis considers neutral, long-lived scalars with masses between 5 and 400 GeV, produced from decays of heavy bosons with masses between 125 and 1000 GeV, where the long-lived scalars decay into Standard Model fermions. The analysis uses either 10.8 fb−1 or 33.0 fb−1 of data (depending on the trigger) recorded in 2016 at the LHC with the ATLAS detector in proton–proton collisions at a centre-of-mass energy of 13 TeV. No significant excess is observed, and limits are reported on the production cross section times branching ratio as a function of the proper decay length of the long-lived particles

Hydrological and Atmospheric Pilot Experiment in the Sahel; experimental plan August 1992

HAPEX-Sahel was a land-surface-atmosphere interaction experiment, carried out in the Sahelian region of West Africa in Niger in 1992. This publication served as a reference for the execution of the experiment. It summarizes scientific objectives and the experimental strategy, and it provides descriptions of the measurement sites and of the contributions of individual investigating teams. Operational details as well as the database strategy are given

Cosmopolitan heterotrophic microeukaryotes are active bacterial grazers in experimental oil-polluted systems

We investigated the population dynamics and prevailing 18S rDNA phylotypes of microeukaryotes (<= 10 mu m) in microcosms containing seawater from either an unpolluted oligotrophic site or a chronically oil-polluted mesotrophic site of the Aegean Sea, amended with crude oil (100 p.p.m. final concentration) and crude oil plus emulsifier (10 p.p.m. final concentration). The addition of oil alone did not result in an important increase of bacteria or their predators, while the addition of oil and emulsifiers caused an important increase in bacteria followed by nanoflagellate predator response. We observed an important shift in the microeukaryotic community structure, which was characterized by the dominance of the same heterotrophic nanoflagellates in all oil-polluted treatments. Thus, the resulting 18S rDNA phylotypes were dominated (48.1-82.4%) by Paraphysomonas foraminifera in all treatments containing crude oil and crude oil plus emulsifier. The origin of the seawater, i.e. unpolluted versus chronically oil-polluted, had no effect on the dominant eukaryote, suggesting that the ubiquitous P. foraminifera is an effective opportunist in oil-polluted aquatic systems. The next dominant phylotypes were Monosiga brevicollis (<= 27.0%) and Pseudobodo tremulans (<= 23.1%). However, the addition of the emulsifier increased the dominance of P. foraminifera but decreased that of M. brevicollis and P. tremulans. Our study revealed that these dominant oil-tolerant eukaryotes, which are commonly found in the marine environments, are important grazers of bacteria and as such their dynamics should be taken into account in bioremediation practices in situ
