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

Using Real-Time Dashboards to Monitor the Impact of Disruptive Events on Real Estate Market. Case of COVID-19 Pandemic in Australia

Real estate markets are complex both in terms of structure and dynamics: they are both influenced by and influence almost all aspects of the economy and are equally vulnerable to the shocks experienced by the broader economy. Therefore, understanding the extent and nature of the impact of large-scale disruptive events such as natural disasters and economic financial downturns on the real estate market is crucial to policy makers and market stakeholders. In addition to anticipating and preparing for long-term effects, it has become imperative for stakeholders to monitor and manage the short-term effects as well due to the emergence of ‘PropTech’ and ‘platform real estate’. In this work, we explore the use of online, real-time dashboards which have been used extensively in the context of urban management, policymaking, citizen engagement and disaster response as an appropriate tool for the purpose of monitoring real estate markets. We describe the process of designing, building, and maintaining an operational dashboard for monitoring the residential real estate market in Australia during the COVID-19 pandemic in 2020. We detail the techniques and methods used in creating the dashboard and critically evaluate their feasibility and usefulness. Finally, we identify the major challenges in the process, such as the spatial and temporal availability and veracity of the real estate market data, and we identify possible avenues for consistent, high-quality data; methodology; and outputs for further research

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.

Can infrastructure, built environment, and geographic factor negate weather impact on Strava cyclists?

Cycling participation is context-sensitive and weather condition is reportedly a significant factor. How weather affects cyclists with different demographics, trip purposes, and in the context of cycling infrastructure, built environment and geographic factors is less well understood by existing literature. This paper applies autoregressive models to explain difference in Strava cycling volume from the same hour of the previous day as a function of change in weather conditions, and day of the week; the contextual effect of cycling infrastructure, built environment and geographic factors is accounted for using interaction terms. We use Strava crowdsourced cycling data in Sydney, Australia, as a case study; commute and leisure cyclists, male and female, young and older cyclists are modeled separately. We find weather conditions have a statistically significant effect on cycling participation; rain, rainfall in the last 2 hours and wind are general deterrents to cycling. Physically separated cycling lanes reduce the adverse effect of precipitation on leisure cyclists and male cyclists but have little effect in retaining commute cyclists and female cyclists. The adverse effect of precipitation and wind on commute cycling is amplified in areas with good access to jobs, possibly due to the availability of better alternative modes of transport. Inland locations generally attenuate effects of windy conditions, except for young adults. This paper sheds light on factors attenuating adverse weather effects on cycling participation and provides useful guidance for future cycling infrastructure
