1. First of the feathers: soldiers and suffragettes 2. Flight and refuge - Folkestone welcomes all

1. It is 1918 and the fight for female suffrage has been partly won. A woman reflects on her own role, campaigning for votes for women, while handing out white feathers to young men on Folkestone Leas during World War 1. This immersive dramatization will explore the possible motivation behind women’s political action between 1914 and 1918, and the impact this had on a generation of men. Suffrage campaigners often disagreed on strategy and policy, and their political views ranged from liberal pacificism to enthusiasm for eugenic selection. School participants will take opposite sides in these highly contentious debates, as the suffragette demands their support, and wants to know why some of them are not in uniform. 2.An exhibition at Folkestone Museum and curated by a local sixth form student, based on research into the Belgian refugee presence in Folkestone during WW1. The exhibition asks why an event so fundamental to our local history remains unknown to so many? Exploring the extent to which the Folkestone community welcomed their neighbours from across the channel in a time of need, the exhibition draws parallels with the modern day immigration crisis, helping to assess how our response to refugees may have changed

Selecting offshore renewable energy futures for Victoria

Australia’s population is continually growing, making land more valuable and adding to energy demand. As the coast of Victoria, Australia has regular high winds, the development of offshore renewable energy is an excellent alternative to conventional energy sources. This provides an opportunity to meet growing energy needs while caring for the environment; and supporting regional communities. There are currently no offshore energy projects in Victoria. This paper investigates demand, supply, feasibility and planning of the wind and wave power options. Analytical (GIS) and visual aids (Google Earth) are used to illustrate these options and so to assist the community in making an informed decision for the renewable energy approaches suitable in Victoria

CORRELATES OF BLACK PARAMILITARY ACTIVITY: AN EXPLORATORY STUDY

One indication of the racial polarization of our society is the rise of black paramilitary organizations. Interviews were conducted with a sample of active members of a black paramilitary organization located in a large Southern city. The young male respondents tended to be alienated, to have records of arrest and imprisonment, and to have served in the armed forces. Yet, they were found to adhere to a Protestant Ethnic and to be fairly representative in terms of economic status. It is suggested that race alone provides the motivation for black paramilitary activities.http://web.ku.edu/~starjrn

Meltwater Intrusions Reveal Mechanisms for Rapid Submarine Melt at a Tidewater Glacier

Submarine melting has been implicated as a driver of glacier retreat and sea level rise, but to date melting has been difficult to observe and quantify. As a result, melt rates have been estimated from parameterizations that are largely unconstrained by observations, particularly at the near-vertical termini of tidewater glaciers. With standard coefficients, these melt parameterizations predict that ambient melting (the melt away from subglacial discharge outlets) is negligible compared to discharge-driven melting for typical tidewater glaciers. Here, we present new data from LeConte Glacier, Alaska, that challenges this paradigm. Using autonomous kayaks, we observe ambient meltwater intrusions that are ubiquitous within 400 m of the terminus, and we provide the first characterization of their properties, structure, and distribution. Our results suggest that ambient melt rates are substantially higher (×100) than standard theory predicts and that ambient melting is a significant part of the total submarine melt flux. We explore modifications to the prevalent melt parameterization to provide a path forward for improved modeling of ocean-glacier interactions.This work was funded by NSF OPP Grants 1503910, 1504191, 1504288, and 1504521 and National Geographic Grant CP4-171R-17.

What affects commute cycling in Sydney: Access, infrastructure and demographics

A better understanding of factors affecting commute cycling will be needed to affect a greater uptake of active transport in many parts of the world, and to facilitate the shift toward more sustainable cities. Commute cycling rates in Sydney is currently low; in this paper we use census data and aggregate level attributes to identify factors affect- ing commute cycling in Sydney, Australia, including (i) road and cycling infrastructure; (ii) the convenience of reaching destinations by cycling (access); and (iii) demographic variables. We find places with high commute cycling levels consistently have good ac- cess to jobs and to cycling infrastructure. Student population has a positive effect on commute cycling rates while areas in the city with a high proportion of East Asian population has a negative effect. This paper highlights the importance of providing cy- cling infrastructure in conjunction with job accessibility in order to encourage commute cycling. Active transport policies should aim to promote commute cycling in historical CBD, and focus on recreational or non-commuting utility cycling in local centers and suburban areas
