2013 Study on Children of Seriously Wounded Service Members
Over the course of one year, researchers from The Caster Family Center for Nonprofit and Philanthropic at the University of San Diego interviewed a total of 125 participants, including seriously wounded service members, their spouses and children, as well as military, civilian and nonprofit professionals who work with this population. The study included two phases to ensure a comprehensive understanding around the population and its unfulfilled needs: The first phase focused on understanding the specific needs of children of seriously wounded service members through interviews, focus groups, and reviews of existing research; the second phase focused on an assessment of government and nonprofit programs available to identify gaps that exist.https://digital.sandiego.edu/npi-military/1003/thumbnail.jp
Where is the Human in HDI?
This position paper views HDI from a human-centred perspective informed by the work of Martin Buber and Eric Fromm. Buberâs ideas of philosophical dialogue (Zank, 2020) concern how humans experience the world and themselves while Frommâs principles of character orientation (Cherry, 2020) , concern how individuals relate to the world. We seek to discuss the associated relational dynamic at play between humans and data, setting out five questions as a provocation
Four Speculative Design F(r)ictions: Designing for Personal Data Awareness
Human Data Interaction (HDI) takes place within a data economy characterised by power imbalances that favour giant corporations that rely on deceptions comprising a form of privacy theatre. We present speculative design f(r)ictions as critical framing devices to help people engage with, reflect upon and understand obfuscated personal data processes, towards supporting their awareness and agency around personal data sharing. We discuss four concept designs we developed following workshop activities
Lethal in small doses : environmental metaphors for privacy protection in the infosphere
Luciano Floridi coined the term infosphere to update the concept of the "ecosphere" for the information society. Just as with the ecosphere, the infosphere is a fragile environment where ruthless commercial practices can cause lasting economic degradation. Mining for data can in this sense be seen as harmful as mining for tin, and if "big data" is really the new oil, then we must be wary of ruthless data barons causing data spills. The paper reports some of the findings and research of an EPSRC funded project on "cumulative revelations", the risks that are generated through seemingly small and individually innocuous disclosure of information, which nonetheless over time accumulates critical potential. We explore how we can use ideas and concepts from environmental science and environmental law to think of better ways to create sustainable data infrastructures in the presence of such "de-minimis" risks that are ill catered for in traditional risk-based approaches to regulatio
A Preliminary Study on Evaluating Cumulative Revelations in Online Personal Data: Introducing a persona-based cyber safety tool for awareness of online risks and harms
Small pieces of personal information shared online that, on their own, seem innocuous, can, when combined, pose significant and unanticipated risks to security and reputation. These are cumulative revelations. Our persona-based digital cyber safety tool explores how well people can make such connections between items and evaluates their awareness of online risks and harms. In a study conducted on Prolific (n=200) using two scenarios (Identify Theft, Online Reputation) participantsâ ability to identify risky posts and piece together revelations varied considerably across the population. Using the tool, a majority reported increased awareness and understanding of risks posed by online behaviour. Using such scenarios, we are learning about how people understand cumulative risks online, while assisting them with learning how to better identify risks posed by digital traces and how to be safer online. Future work will explore the toolâs application in different employment domains
Making sense of trifles : data narratives and cumulative data disclosure
The law does not concern itself with trifles. If a risk is deemed minimal, or an infraction negligible, invoking the authority of the law often seems unnecessary. However, there are increasingly fields of human activity where this principle leads to gaps in the protection neces- sary for a flourishing society. This paper reports findings and ideas from a research project in cumulative data disclosure, where an aggregation of in themselves harmless data points can expose the users of social media to significant personal risk
Grace Under Pressure: a drama-based approach to tackling mistreatment of medical students
A positive and respectful learning environment is fundamental to the development of professional identities in healthcare. Yet medical students report poor behaviour from healthcare professionals that contradict professionalism teaching. An interdisciplinary group designed and implemented a drama-based workshop series, based on applied theatre techniques, to help students develop positive professional qualities and interpersonal skills to deal with challenges in the healthcare setting. We piloted the workshops at the University of Sydney in 2015. Attendees completed evaluation questionnaires and participated in a focus group or interview. Of 30 workshop attendances, there were 29 completed questionnaires and three participants attended a focus group or interview. Workshop activities were rated as âvery goodâ or âgoodâ by 21/22; (95.5%). Thematic analysis of qualitative data highlighted the rationale for participation (to deal with bullying, prevent becoming a bully, learn social skills), workshop benefits (express emotions, learn about status dynamics and deconstructing personalities, empathy, fun), challenges (meeting participantsâ expectations, participantsâ need for further practice), and implications for medical education (need to develop awareness of othersâ perspectives). Our research has shown that there is momentum to challenge mistreatment in medical education. While a multipronged approach is needed to generate systemic change, this pilot offers a positive and creative innovation. It helps students improve their interpersonal skills and sense of self to deal with challenges in the healthcare setting, including mistreatment
Weak Lensing with SDSS Commissioning Data: The Galaxy-Mass Correlation Function To 1/h Mpc
(abridged) We present measurements of galaxy-galaxy lensing from early
commissioning imaging data from the Sloan Digital Sky Survey (SDSS). We measure
a mean tangential shear around a stacked sample of foreground galaxies in three
bandpasses out to angular radii of 600'', detecting the shear signal at very
high statistical significance. The shear profile is well described by a
power-law. A variety of rigorous tests demonstrate the reality of the
gravitational lensing signal and confirm the uncertainty estimates. We
interpret our results by modeling the mass distributions of the foreground
galaxies as approximately isothermal spheres characterized by a velocity
dispersion and a truncation radius. The velocity dispersion is constrained to
be 150-190 km/s at 95% confidence (145-195 km/s including systematic
uncertainties), consistent with previous determinations but with smaller error
bars. Our detection of shear at large angular radii sets a 95% confidence lower
limit , corresponding to a physical radius of
kpc, implying that galaxy halos extend to very large radii. However, it is
likely that this is being biased high by diffuse matter in the halos of groups
and clusters. We also present a preliminary determination of the galaxy-mass
correlation function finding a correlation length similar to the galaxy
autocorrelation function and consistency with a low matter density universe
with modest bias. The full SDSS will cover an area 44 times larger and provide
spectroscopic redshifts for the foreground galaxies, making it possible to
greatly improve the precision of these constraints, measure additional
parameters such as halo shape, and measure the properties of dark matter halos
separately for many different classes of galaxies.Comment: 28 pages, 11 figures, submitted to A
Verbatim Theater: Prompting Reflection and Discussion about Healthcare Culture as a Means of Promoting Culture Change
Problem: The mistreatment of medical and nursing students and junior health professionals
has been reported internationally in research and the media. Mistreatment can be
embedded and normalized in hierarchical healthcare workplaces, limiting the effectiveness
of policies and reporting tools to generate change; as a result, some of those who experience
mistreatment later perpetuate it. We used a novel, creative approach, verbatim theater,
to highlight the complexity of healthcare workplaces, encourage critical reflection, and support
long-term culture change. Intervention: Verbatim theater is a theater-for-change documentary
genre in which a playscript is devised using only the words spoken by informants.
In 2017, 30 healthcare students and health professionals were recruited and interviewed
about their experience of work and training by the multidisciplinary Sydney Arts and Health
Collective using semi-structured interviews. Interview transcripts became the primary material
from which the script for the verbatim theater play âGrace Under Pressureâ was developed.
The performing arts have previously been used to develop the communication skills of
health professional students; this esthetic expression of the real-life effects of healthcare
workplace culture on trainees and students was implemented to stimulate consciousness of,
and dialogue about, workplace mistreatment in healthcare work and training. Context: The
play premiered at a major Sydney theater in October 2017, attended by the lay public and
student and practicing health professionals. In November 2017, three focus groups were
held with a sample of audience members comprising healthcare professionals and students.
These focus groups explored the impact of the play on reflection and discussion of healthcare
culture and/or promoting culture change in the health workplace. We analyzed the
focus group data using theoretical thematic analysis, informed by Turnerâs theory of the
relation between âsocialâ and âestheticâ drama to understand the impact of the play on its
audience. Impact: Focus group members recognized aspects of their personal experience of
professionalism, training, and workplace culture in the play, Grace Under Pressure. They
reported that the playâs use of real-life stories and authentic language facilitated their critical
reflection. Participants constructed some learning as ârevelation,â in which the play enabled
them to gain significant new insight into the culture of health care and opened up discussions
with colleagues. As a result, participants suggested possible remedies for unhealthy
aspects of the culture, including systemic issues of bullying and harassment. A small number
of participants critiqued aspects of the play they believed did not adequately reflect their
experience, with some believing that the play over-emphasized workplace mistreatment.
Lessons Learned: Verbatim theater is a potent method for making personal experiences of
healthcare workplace and training culture more visible to lay and health professional audiences.
In line with Turnerâs theory, the playâs use of real-life stories and authentic language
enabled recognition of systemic challenges in healthcare workplaces by training and practicing
health professionals in the audience. Verbatim theater provides a means to promote
awareness and discussion of difficult social issues and potential means of addressing them
Oscillatory surface rheotaxis of swimming E. coli bacteria
Bacterial contamination of biological conducts, catheters or water resources
is a major threat to public health and can be amplified by the ability of
bacteria to swim upstream. The mechanisms of this rheotaxis, the reorientation
with respect to flow gradients, often in complex and confined environments, are
still poorly understood. Here, we follow individual E. coli bacteria swimming
at surfaces under shear flow with two complementary experimental assays, based
on 3D Lagrangian tracking and fluorescent flagellar labelling and we develop a
theoretical model for their rheotactic motion. Three transitions are identified
with increasing shear rate: Above a first critical shear rate, bacteria shift
to swimming upstream. After a second threshold, we report the discovery of an
oscillatory rheotaxis. Beyond a third transition, we further observe
coexistence of rheotaxis along the positive and negative vorticity directions.
A full theoretical analysis explains these regimes and predicts the
corresponding critical shear rates. The predicted transitions as well as the
oscillation dynamics are in good agreement with experimental observations. Our
results shed new light on bacterial transport and reveal new strategies for
contamination prevention.Comment: 12 pages, 5 figure
