BOX: One Minute Volume 3

BOX is a digital short originally developed in 2004 documented on a 1920’s box camera. This early moving image work formed the basis of a practice which interrogates our experience of moving image through the remediation of analogue technology with new media. In 2009 it was included in One Minute Volume 3; a programme of artists moving image curated by Kerry Baldry including work by: Tony Hill, Tina Keane, Katherine Meynell, Kayla Parker and Stuart Moore, Dave Griffiths, Marty St James Alex Pearl and Nick Jordan.</p

Sources of Nest Failure in Mississippi Sandhill Cranes, Grus canadensis pulla: Nest Survival Modeling and Predator Occupancy

Low recruitment is the largest challenge facing the recovery of the critically endangered Mississippi Sandhill Crane (Grus canadensis pulla). Lack of information on sources of nest failure hinders effective management to increase recruitment. I examined sources of nest failure for 54 nests at the Mississippi Sandhill Crane National Wildlife Refuge, 2008-2009. Nest cameras identified predation as the primary source of failure, followed by flooding, abandonment, and egg inviability. Mean daily survival rate (DSR) was 0.72. The best approximating models included covariates for season date, temperature and nest age. DSR decreased with increasing season date, increasing nest age, and decreasing temperature. Hypotheses related to effects of renesting, human disturbance, precipitation, flooding, and winter rain were not supported. Because predation has been identified as a primary source of nest failure, I also monitored mammalian predators on the MSCNWR. Coyotes and raccoons were most common, with gray foxes, red foxes, domestic dogs, and bobcats also detected frequently

Evaluation of Energy Release from Wildfires Across the Elevation Gradient

Wildfires are an integral process in vegetative terrestrial land which shape ecosystem functions. A warming climate, however, has increased the size and severity of fires with significant ecosystem and societal implications. Furthermore, warming has changed characteristics of wildfires enabling a median upslope advance of 252 m in high-elevation forest fires from 1984 to 2017, allowing wildfires to burn in areas that were previously too wet to burn frequently. This exposed an additional 81,500 square kilometers (11%) of western US montane forests to fires. In this thesis, I test the hypothesis that wildfires burn more intensely in high-elevation mesic forests than low-elevation dry forests. To this end, I assess fire intensity, which refers to how much heat energy is released during a fire, across the elevation gradient. I use satellite-observed fire radiative power (FRP) that measures the amount of radiant energy released from burning vegetation during a wildfire event as a proxy for fire intensity. FRP data are acquired from the MODIS sensor aboard Terra and Aqua satellites for fires between 2000 and 2021 which are then paired with elevation data using digital elevation maps. I derive this data for the 15 mountainous ecoregions of the western US and conduct various hypothesis tests to determine whether or not there is a statistically significant trend in FRP as a function of elevation. I will also assess whether or not the distribution of FRP for high-elevation and low-elevation wildfires are equal. Among the 15 studied mountainous ecoregions, 12 ecoregions are associated with a statistically significant increasing FRP as a function of elevation, 1 is associated with statistically non-significant increase in FRP as a function of elevation, and 2 were associated with statistically significant decreasing FRP as a function of elevation. I note the limitations of satellite-derived FRP, including twice-a-day overpass of satellite over fires, limitations of the MODIS sensor in capturing small fires, and algorithmic errors in inferring FRP from thermal anomaly observations. Nevertheless, long-term (20+ years) observation of FRP provides unparalleled opportunities for geospatial and temporal analysis of trends in fire intensity. Furthermore, quantile regression analysis revealed that higher intensity fires increase at a higher rate compared to lower intensity fires as a function of elevation. Finally, my analysis showed that 10 of the studied ecoregions are associated with statistically significant increase in FRP as a function of year (i.e., fires are intensifying in recent years), 1 has a statistically non-significant increasing trend, 2 ecoregions don’t show any trend in FRP as a function of year, and 2 are associated with statistically non-significant trends in FRP versus year. High-elevation wildfires and their intensity are important for societal and ecological systems that are affected by wildfires. They impact, for example, quantity and quality of water resources for 70% of the western US population that depend on high-elevation areas as their source of water. Understanding this phenomenon can inform wildfire and land management in a warming climate

Addressing Moral Distress in Critical Care Nurses: A Pilot Study

Background: Moral distress can affect critical care nurses caring for complex patients. It can result in job dissatisfaction, loss of capacity for caring, and nurse turnover, resulting in a negative impact on quality care. Aim: This study purpose was to determine how moral distress impacts critical care nurses (adult and pediatric) and to implement improvement strategies to reduce moral distress, improve job satisfaction, and retention. Theoretical framework: Nathaniel’s Theory of Moral Reckoning was the grounded theory used to show the application of the improvement interventions. Methods: Phase 1 was a cross-sectional design using the 26-item Hospital Ethical Climate Survey (HECS) and the 21-item Moral Distress Scale-Revised (MDS-R). Phase 2 consisted of a mixed-method design employing focus group interviews, interventions, and pre- and posttest. Results: Pediatric nurses reported lower mean moral distress composite scores 21.71 (15.47) as compared to the adult nurses 88.75 (64.7). For adult nurses, a strong correlation existed between ethical climate and moral distress (rs = -0.62, n = 10, p = 0.05), with high levels of ethical climate associated with lower levels of moral distress. The cohort group identified personal and professional impact of moral distress with some differences between the pediatric and adult nurses related to the source of moral distress responses to suffering. The 3-month post survey showed a total moral distress score for one adult critical care nurse decreased from 158 to 74. The remaining three nurses’ scores were unchanged. All four nurses were not considering leaving their position now. All participants either agreed or strongly agreed the education and action plan reduced their moral distress. Conclusion: A blended-learning training to include American Association of Critical Care Nurses’ (AACN) 4As, communication and ethical reasoning skills, and personal action plans helped manage moral distress, aided retention, and improved satisfaction of critical care nurses

Engaging Indigenous economy: a selected annotated bibliography of Jon Altman’s writings 1979‒2014

This annotated bibliography aims to summarise many of the themes to which Jon Altman, foundation director of the Centre for Aboriginal Economic Policy Research, has dedicated his career to date. Abstract \u27Engaging Indigenous Economy: A Selected Annotated Bibliography of Jon Altman’s Writings 1979–2014\u27 is published in conjunction with the conference ‘Engaging Indigenous economy: Debating diverse approaches’, convened at the Australian National University, 4–5 September 2014. The publication and conference coincide with Jon Altman’s retirement from the Centre for Aboriginal Economic Policy Research (CAEPR), where he was foundation director from 1990 to 2010. The annotated bibliography aims to summarise many of the themes to which Altman has dedicated his career to date, and is designed to be a navigational tool for paper presenters, conference delegates and others wishing to engage with Altman’s work. The bibliography was written in conversation with Jon Altman and is structured around the six conference themes selected by conveners Kirrily Jordan, Tim Rowse and Will Sanders to reflect Altman’s writings: comparative modern hunter–gatherer studies; economic hybridity and alternate development; employment and labour markets; land rights and native title; sustainable land-based indigenous livelihoods; and neoliberalism or the return of the guardian state? The bibliography has its basis in an earlier publication, The Hybrid Economy Topic Guide, prepared by Susie Russell as an element of the Australian Research Council Discovery project ‘Hybrid economic futures for remote Indigenous Australia: Linking poverty reduction and natural resource management’. In looking to update this topic guide in early 2014, a decision was made to considerably extend its coverage to encompass a far wider selection of Altman’s published research. Given the breadth of Altman’s research over a long career, it has not been possible to include all of his published work; however, the bibliography covers a large proportion of his written contribution. Classification of works according to the conference themes has required judgments, as many publications could be allocated to more than one theme. The authors have sought to address the challenge of some inevitable arbitrary judgment by developing a set of keywords for each annotated item

Hide and seek: playing with visibility

Metaphors and practices of visibility are central to debate about participatory art practices, including: the way institutions seek visible evidence of community engagement (Pollock & Sharp 2012); how artists may intend to make marginalized people visible (Wright 2008); how participation can make participants less, not more visible (Wright, 2008); how collaboration may be conceived as a way of seeing each other (Shaw, 2013); and how critical art practices seek to make hidden power structures visible (Lütticken, 2015). In the following, a collaborative project with a group of nursing and midwifery research students is explored, focusing particularly on practical experiments with visibility. In 2016 Kings College London and Somerset House’s Utopia project celebrated the 500th anniversary of More’s novel, with artworks and student engagement. From early conversations about utopia as a no-place, the students focused on transition between expert practitioners to novice researchers. Anxiety about how they ‘appear’ as researchers evolved into a conversation about the visibility of patients and research subjects, and a task to explore the value of seeing, witnessing, observing, experiencing and feeling, as researcher and practitioner. Later we spent time playing hide and seek at a medical ward simulation centre- itself a place between real and fiction and where performance is measured. Initially doubting the feasibility of hiding in a transparent, clinical space, the research students became experts, using subterfuge, distraction and bluff. Hiders and seekers took camera footage, so catching the person’s image was innately tied to hiding or seeking. In exploring the qualities of visibility in roles for our Kings’ students, the work also openly problematizes their visible presence as participants in our art process too. The work then, offers the means to see the social mechanism by which things and people become visible

Heavy Baryons and electromagnetic decays

In this talk I review the theory of electromagnetic decays of the ground state baryon multiplets with oneheavy quark, calculated using Heavy Hadron Chiral Perturbation Theory. The M1 and E2 amplitudes for (S^{*}-> S gamma), (S^{*} -> T gamma) and (S -> T gamma)are separately analyzed. All M1 transitions are calculated up to O(1/\Lambda_\chi^2). The E2 amplitudes contribute at the same order for (S^{*}-> S gamma), while for (S^{*} -> T gamma) they first appear at O(1/(m_Q \Lambda_\chi^2))and for (S -> T gamma) are completely negligible. Once the loop contributions is considered, relations among different decay amplitudes are derived. Furthermore, one can obtain an absolute prediction for the widths of Xi^{0'(*)}_c-> Xi^{0}_c gamma and Xi^{-'(*)}_b-> Xi^{-}_b gamma.Comment: Talk presented at 4^{th} International Conference Hyperons, Charm and Beauty Hadrons Conference, Valencia June 200
