Gender and family in transnational entrepreneurship
The current process of globalisation is not only about increasing cross–border flows of capital, goods and services, but also about people moving often from developing to developed areas in search of a better life. The role of women in these dislocations is increasing as they are counted on to provide for their families, while in many cases still expected to conform to traditional nurturing roles ...

A critical thinking challenge for the chief of staff: a case study
A military college for organisational–level leaders identified the improvement of the critical thinking (CT) curriculum as a high priority. The first cycle of design, development and implementation was not successful due to a lack of time and assembling a team that did not have representation from all teaching departments, curriculum developers, and operations staff. After conducting a detailed ...

Experimental study of turbulence and vertical temperature profile in the urban boundary layer
We observed the turbulence and vertical profile of temperature in and above the roughness sublayer (RS) using a tower, a tethered balloon and a Doppler sodar in Himeji City. A 3–D ultrasonic anemometer–thermometer was sited at a height of 54 m on the tower. The present results showed that in the RS, the ratio of friction velocity to wind speed, u* /u, observed under unstable conditions of −4.2 ...

An investigation of the urban heat island of Rome through a canyon–based subgrid scheme
This paper describes some modifications to a mesoscale model surface scheme to better account for urban heat–storage. The approach involves integrating the Subgrid Town Energy Budget (STEB) with the Regional Atmospheric Modelling System (RAMS). The integrated system has been applied to the investigation of the Urban Heat Island (UHI) of Rome, Italy, and the surrounding area (Lazio Region), ...

Comparison of two point–to–point protocols for transport and dispersion model evaluations
Historically, assessments of transport and dispersion models have involved comparisons to field trial data using quantities derived from observations - e.g., maximum concentrations or plume widths. Recently, several methodologies that compare observations and predictions paired in space and time have been developed. Two protocols designed to deal with low observed or predicted values have ...

Potential use of transport and dispersion model output to supplement Allied Tactical Publication–45 hazard area prediction templates
Allied Tactical Publication–45(C) is the current US and NATO command doctrine for Nuclear, Chemical and Biological (NBC) events. ATP–45 is designed to warn military populations of NBC hazard by providing area–warning templates based on NBC messages. ATP–45 is designed to produce a single 2–hour hazard area template that accounts for wind speed fluctuations, but it ...

Source reconstruction: a statistical mechanics perspective
A Bayesian inference scheme is used to address the problem of general source reconstruction. To this purpose, starting from a simple, physically motivated structure–based representation for a general source distribution, Bayesian probability theory is used to formulate the full joint posterior probability density function for the parameters in this representation. The exploration of the ...

Contribution of CO2 emitted to the atmosphere by diffuse degassing from volcanoes: The Furnas Volcano case study
Furnas Volcano is a dormant central volcano located in the eastern part of São Miguel Island (Azores archipelago, Portugal). The last volcanic eruption in this volcanic system took place in 1630 causing about 200 victims. Present–day activity comprises fumarolic fields, thermal and cold CO2–rich springs and soil diffuse degassing areas. CO2 diffusely released from the volcano soils was estimated ...

Statistical approach to estimate the impact of climate change on daily ozone concentrations
Short–term exposure to ozone is a public health concern worldwide. Surface ozone is a secondary air pollutant, formed primarily through a complex series of photochemical reactions between nitrogen oxides and reactive hydrocarbons. Hot days with clear skies favour ozone production. Hence, a warmer climate is likely to increase ozone ambient concentration and consequently, the impact of ...

Equity, quantum physics, dreamtime and nature's title
The origins of the equitable jurisdiction were premised on correcting defects in the common law to prevent unconscionable conduct. Although property law presupposes separation of person from place, a court of equity may be persuaded by scientific evidence, which supports an interconnected and interdependent world, where person cannot be separated from nature, nor from place. Australian aboriginal ...

ADMS–Urban: developments in modelling dispersion from the city scale to the local scale
Many countries perform national air quality assessments using grid–based numerical air dispersion models, generally referred to as 'regional' models. Advantages of these models include the ability to use temporally and spatially varying meteorology and model chemical reactions over large temporal and spatial scales. These models usually perform reasonably well against rural and urban background ...

Calculations of external irradiation from radioactive plume in the early stage of a nuclear accident
A mathematical method for real–time calculations of cloudshine doses/dose rates used for purposes of online assimilation of model predictions with observations incoming from terrain is proposed. Model predictions of cloudshine doses have to be calculated simultaneously in an array of positions located on terrain around a nuclear facility. A modification of the classical straight–line Gaussian ...

Estimates of lateral dispersion parameters in low wind speed conditions
Wind speed time series recorded during stable low wind speed conditions are typically non–stationary, with large horizontal oscillations, commonly known as meandering. In this paper, two wavelet–based methods are proposed to obtain lateral dispersion coefficients from such time series. These methods, associated with a specific wind model, have been tested by using wind velocities recorded, with ...
