Momentum-space engineering of gaseous Bose-Einstein condensates
We show how the momentum distribution of gaseous Bose--Einstein condensates
can be shaped by applying a sequence of standing-wave laser pulses. We present
a theory, whose validity for was demonstrated in an earlier experiment [L.\
Deng, et al., \prl {\bf 83}, 5407 (1999)], of the effect of a two-pulse
sequence on the condensate wavefunction in momentum space. We generalize the
previous result to the case of pulses of arbitrary intensity separated by
arbitrary intervals and show how these parameters can be engineered to produce
a desired final momentum distribution. We find that several momentum
distributions, important in atom-interferometry applications, can be engineered
with high fidelity with two or three pulses.Comment: 13 pages, 4 figure
A protocol for co-creating research project lay summaries with stakeholders:Guideline development for Canada's AGE-WELL Network
Background
Funding bodies increasingly require researchers to write lay summaries to communicate projects’ real-world relevance to the public in an accessible way. However, research proposals and findings are generally not easily readable or understandable by non-specialist readers. Many researchers find writing lay summaries difficult because they typically write for fellow subject specialists or academics rather than the general public or a non-specialist audience. The primary objective of our project is to develop guidelines for researchers in Canada’s AGE-WELL Network of Centres of Excellence, and ultimately various other disciplines, sectors, and institutions, to co-create lay summaries of research projects with stakeholders. To begin, we produced a protocol for co-creating a lay summary based on workshops we organized and facilitated for an AGE-WELL researcher. This paper presents the lay summary co-creation protocol that AGE-WELL researchers will be invited to use.
Methods
Eligible participants in this project will be 24 AgeTech project researchers who are funded by the AGE-WELL network in its Core Research Program 2020. If they agree to participate in this project, we will invite them to use our protocol to co-produce a lay summary of their respective projects with stakeholders. The protocol comprises six steps: Investigate principles of writing a good lay summary, identify the target readership, identify stakeholders to collaborate with, recruit the identified stakeholders to work on a lay summary, prepare for workshop sessions, and execute the sessions. To help participants through the process, we will provide them with a guide to developing an accessible, readable research lay summary, help them make decisions, and host, and facilitate if needed, their lay summary co-creation workshops.
Discussion
Public-facing research outputs, including lay summaries, are increasingly important knowledge translation strategies to promote the impact of research on real-world issues. To produce lay summaries that include information that will interest a non-specialist readership and that are written in accessible language, stakeholder engagement is key. Furthermore, both researchers and stakeholders benefit by participating in the co-creation process. We hope the protocol helps researchers collaborate with stakeholders effectively to co-produce lay summaries that meet the needs of both the public and project funders
Doing gender locally: The importance of ‘place’ in understanding marginalised masculinities and young men’s transitions to ‘safe’ and successful futures
Observable anxieties have been developing about the position of boys and young men in contemporary society in recent years. This is expressed as a crisis of masculinity, in which place is often implicitly implicated, but is rarely considered for its role in the shaping of young men’s practices, trajectories and aspirations. Drawing on research conducted with young people who accessed a range of social care support services, this article argues that transition means different things for young men in different locales and that local definitions of masculinity are required to better understand young men’s lives and the opportunities available to them. The authors argue that home life, street life, individual neighbourhoods, regions and nations all shaped the young men’s identities and the practices they (and the staff working with them) drew on in order to create successful futures and ‘safe’ forms of masculinity. It is suggested that this place-based approach has the potential to re-shape the ‘crisis’ discourse surrounding masculinity and the anxieties associated with young men
Learning through social spaces: migrant women and lifelong learning in post-colonial London
This article shows how migrant women engage in learning through social spaces. It argues that such spaces are little recognised, and that there are multiple ways in which migrant women construct and negotiate their informal learning through socialising with other women in different informal modes. Additionally, the article shows how learning is shaped by the socio-political, geographical and multicultural context of living in London, outlining ways in which gendered and racialised identities shape, construct and constrain participation in lifelong learning. The article shows that one way in which migrant women resist (post)colonial constructions of difference is by engaging in informal and non-formal lifelong learning, arguing that the benefits are (at least) two-fold. The women develop skills (including language skills) but also use their informal learning to develop what is referred to in this article as 'relational capital'. The article concludes that informal lifelong learning developed through social spaces can enhance a sense of belonging for migrant women

Glass ceilings and stone floors: an intersectional approach to challenges UK geographers face across the career lifecycle
While there has been a steady growth of women working in geography in UK universities since the mid-Twentieth Century, there are continuing challenges in gendered career progression and professional interactions within the contemporary discipline. These range from problems associated with employment precarity and inflexible work practices, life choices and obligations in the domestic arena, discrimination and bullying, to less tangible gendered norms and cultures in the workplace. This paper discusses these challenges and inequalities in the light of a brief overview of sector-wide statistical data on appointments by gender and career-stage and with the analysis of some 250 in-depth responses to a nationwide qualitative survey of gender and career experience in UK universities (Maddrell et al 2016). While the term ‘glass ceiling’ still has significant relevance, findings show a more complicated picture which also includes ‘stone floors’ and stumbling blocks. It also shows how career experience varies by institution and individual: challenges in career progression can be compounded by institutional protocols and intersectional factors, and vary with career stage. The intersection of early-career job precarity, reproductive decisions and associated family responsibilities were particularly highlighted in this study. These ‘pinch points’ in career development disproportionately affect, but are not limited to, female early career scholars. Early career progress may be stalled in mid-career in multi-staged promotional systems such as that in UK universities; some from minorities face compound barriers; men with caring responsibilities may face prejudice. The paper concludes with suggested strategies for change, highlighting the importance of individual university and department protocols and practices; line manager and other senior colleagues’ attitudes and leadership in creating workplaces with an equality-driven ethos and structures that allow individuals to flourish

Regions of High Out-Of-Hospital Cardiac Arrest Incidence and Low Bystander CPR Rates in Victoria, Australia
BACKGROUND: Out-of-hospital cardiac arrest (OHCA) remains a major public health issue and research has shown that large regional variation in outcomes exists. Of the interventions associated with survival, the provision of bystander CPR is one of the most important modifiable factors. The aim of this study is to identify census areas with high incidence of OHCA and low rates of bystander CPR in Victoria, Australia. METHODS: We conducted an observational study using prospectively collected population-based OHCA data from the state of Victoria in Australia. Using ArcGIS (ArcMap 10.0), we linked the location of the arrest using the dispatch coordinates (longitude and latitude) to Victorian Local Government Areas (LGAs). We used Bayesian hierarchical models with random effects on each LGA to provide shrunken estimates of the rates of bystander CPR and the incidence rates. RESULTS: Over the study period there were 31,019 adult OHCA attended, of which 21,436 (69.1%) cases were of presumed cardiac etiology. Significant variation in the incidence of OHCA among LGAs was observed. There was a 3 fold difference in the incidence rate between the lowest and highest LGAs, ranging from 38.5 to 115.1 cases per 100,000 person-years. The overall rate of bystander CPR for bystander witnessed OHCAs was 62.4%, with the rate increasing from 56.4% in 2008-2010 to 68.6% in 2010-2013. There was a 25.1% absolute difference in bystander CPR rates between the highest and lowest LGAs. CONCLUSION: Significant regional variation in OHCA incidence and bystander CPR rates exists throughout Victoria. Regions with high incidence and low bystander CPR participation can be identified and would make suitable targets for interventions to improve CPR participation rates
