DOES ECONOMIC VULNERABILITY DEPEND ON PLACE OF RESIDENCE? ASSET POVERTY ACROSS THE RURAL-URBAN CONTINUUM

This paper uses Panel Study of Income Dynamics data for 1989, 1994, and 1999 to examine why some U.S. households are asset poor; that is, why households have insufficient resources to invest in their future or to sustain household members at a basic level during times of economic disruption. The study contributes to an improved understanding of asset poverty's correlates by examining the influence of place of residence; the extant literature has focused on individual-level explanations. We estimate a random-effects logistic model of the probability that an individual is asset poor at a given point in time as a function of household-level (e.g. age, gender, race of the household head and family structure) and place-level (regional and rural-urban continuum) variables. The central finding of the paper is that place of residence is an important determinant of asset poverty, above and beyond the influence of household characteristics. We find that living in a central metropolitan county and in a nonmetropolitan area is associated with a higher risk of being asset poor, all else being equal. Implications for future research are discussed.Food Security and Poverty,

Quality Improvement of Workflow for Contrast-Enhanced Mammography

This project is a workflow quality improvement for Contrast-Enhanced Mammography (CEM) at Rush Breast Imaging. With this new technology being implemented, workflow improvement has been noted. The method used in this initiative was Plan-Do-Study Act (PDSA) and involved observation while exams were being performed. Standard operating procedures (SOP’s) were written up for internal stakeholders. Findings are monitored from feedback given from internal and external stakeholders on the workflow setup. Findings that have been noted so far are: issues starting IV’s, limited positioning of patients, and communication on certain areas with the procedure. Since this exam is still new, continued adjustments to the workflow will be made from workflow observations and feedback

"Are You Planning to Follow Your Route?" The Effect of Route Exchange on Decision Making, Trust, and Safety

The Sea Traffic Management (STM) Validation project is a European based initiative which focuses on connecting and updating the maritime world in real time, with efficient information exchange. The purpose of this paper is to evaluate two functions developed during the project: a ship to ship route exchange (S2SREX) function and rendezvous (RDV) information layer, collectively referred to as S2SREX/RDV. S2SREX displays the route segment consisting of the next seven waypoints of the monitored route of a collaborating ship and the RDV layer that predicts a meeting point. S2SREX/RDV provides supplementary information to data acquired by existing navigation systems and is intended to improve situational awareness and safety through a more comprehensive understanding of the surrounding traffic. Chalmers University of Technology and Solent University completed an experiment using twenty-four experienced navigators in bridge simulators. Six traffic scenarios were developed by subject matter experts and tested with and without S2SREX/RDV functionalities. Qualitative data were collected using post-test questionnaires and group debriefs to evaluate the participants\u27 perceptions of S2SREX/RDV in the various traffic scenarios, and quantitative data were collected to assess the ship distances and behavior in relation to the International Regulations for Preventing Collisions at Sea (COLREGs). The results revealed that participants generally trusted the S2SREX/RDV information, and most used S2SREX/RDV for decision support. The quantitative assessment revealed that the COLREGs were breached more often when S2SREX/RDV was used. Experimental findings are discussed in relation to safety, trust, reliance, situational awareness, and human-automation interaction constructs

An evaluation of low-level automation navigation functions upon vessel traffic services work practices

The Sea Traffic Management (STM) Validation Project is a European-based initiative with ambitions to improve maritime safety and efficiency through information sharing in real time. The purpose of this paper is to evaluate the “STM services,” which can be categorized as low-level automated functions designed to improve information exchange between ship and shore. Full-scale simulated scenarios were developed and tested on 16 professional vessel traffic service (VTS) operators comparing VTS operations as they are today with the added STM functionality. Data collection involved observations which assessed the frequency and type of interactions between ships and VTS, followed by questionnaires to provide an overall assessment of the user experience. The results indicate that the frequency and method of communication patterns between VTS operators and ships will be affected by the integration of the STM services. Additional access to navigational information could change the role of VTS operators in traffic situations compared with traditional operations. This paper discusses the findings from a socio-technical systems perspective while also addressing the individual STM services and their potential impact on VTS operations. This research provides valuable information for European VTS centers that could be affected by the implementation of e-Navigation and, specifically, the STM services

Operationalizing COLREGs in SMART ship navigation

The maritime industry is undergoing a transformation driven by digitalization and connectivity. The technological realization of Maritime Autonomous Surface Ships (MASS) presents significant challenges for the maritime human factors research community. These challenges relate to system design, human-automation interaction, stakeholder training, use and acceptance of new technology systems, and on a larger scale, how the regulatory framework, including the Collision Regulations (COLREGs) will be impacted within a MASS system. Decision support is the next step in the transformation towards more connected ships, however, such systems for navigation are largely unexplored from the users’ perspective.The decision support system studied in this project was developed by W\ue4rtsil\ue4 and is called Advanced Intelligent Manoeuvring (AIM), aligning with “low-level automation” or Level 1 (out of a 4-level progression) of MASS. AIM can generate suggestions for course or speed alterations based on data from surrounding traffic. A full-mission bridge simulator study was conducted at Chalmers University of Technology in Gothenburg, Sweden with nineteen Swedish navigators. Three traffic scenarios each with three ships were completed in both baseline (no AIM) and AIM conditions. A mixed methods data collection and analysis approach was employed using questionnaires, collective interviews, and an evaluation of the ship tracks. The results show that the navigators perceive AIM as an advisory tool, to visualize how traffic situations could unfold, an outcome currently difficult for most navigators to conceive. This report discusses the present and near future of the maritime sociotechnical system, highlighting the benefits of automation, while remaining vigilant about the potential dangers

Long-Range Exciton Diffusion in Two-Dimensional Assemblies of Cesium Lead Bromide Perovskite Nanocrystals

F\"orster Resonant Energy Transfer (FRET)-mediated exciton diffusion through artificial nanoscale building block assemblies could be used as a new optoelectronic design element to transport energy. However, so far nanocrystal (NC) systems supported only diffusion length of 30 nm, which are too small to be useful in devices. Here, we demonstrate a FRET-mediated exciton diffusion length of 200 nm with 0.5 cm2/s diffusivity through an ordered, two-dimensional assembly of cesium lead bromide perovskite nanocrystals (PNC). Exciton diffusion was directly measured via steady-state and time-resolved photoluminescence (PL) microscopy, with physical modeling providing deeper insight into the transport process. This exceptionally efficient exciton transport is facilitated by PNCs high PL quantum yield, large absorption cross-section, and high polarizability, together with minimal energetic and geometric disorder of the assembly. This FRET-mediated exciton diffusion length matches perovskites optical absorption depth, opening the possibility to design new optoelectronic device architectures with improved performances, and providing insight into the high conversion efficiencies of PNC-based optoelectronic devices

Resultado do tratamento operatório do aneurisma da aorta abdominal roto contido crônico: estudo caso-controle

OBJECTIVE: To establish, in a case-control study, the early mortality and long-term survival after surgical correction of sealed rupture abdominal aortic aneurysm, compared to controls who underwent standard, nonruptured abdominal aortic aneurysm repair. PATIENTS AND METHODS: From January 1992 to December 2002, 465 patients underwent infrarenal abdominal aortic aneurysm repair. Of those, 13 had sealed rupture abdominal aortic aneurysm (2.8%). These cases were compared to 26 controlsin which surgical repair was performed immediately preceding or succeeding each one of the sealed rupture abdominal aortic aneurysm surgeries. RESULTS: Age, sex, risk factors for atherosclerosis, associated disease, and cardiac ischemia were similar between groups. Patients with sealed rupture abdominal aortic aneurysm presented a higher incidence of lumbar pain than controls (92.3% versus 3.9%; P < .001); fever and weight loss were detected in 5 (38.5%) patients with SAAA and in none of controls (P = .0022). Mean red blood cell transfusion was greater for sealed rupture abdominal aortic aneurysm than controls (1,516 &plusmn; 697 vs. 773 &plusmn; 463 mL (P = .0003). Postoperative complications were similar between groups. Early mortality was 7.7% for sealed rupture abdominal aortic aneurysm and 0% for controls. Five-year survival was significantly lower for sealed rupture abdominal aortic aneurysm (68.4%) than for controls (84.4%, P = .04). CONCLUSION: We conclude that sealed rupture abdominal aortic aneurysm presents diagnostic and surgical challenges that can be adequately managed, achieving early postoperative mortality and complication rates that are similar to standard abdominal aortic aneurysm. However, patients with sealed rupture abdominal aortic aneurysm present higher mortality in the long term compared with patients having standard abdominal aortic aneurysm.OBJETIVO: Estabelecer, através de um estudo caso-controle, a mortalidade precoce e sobrevida a longo prazo após o tratamento cirúrgico do aneurisma da aorta abdominal roto contido crônico comparada aos respectivos controles, submetidos ao reparo do aneurisma da aorta abdominal não roto, operado eletivamente. PACIENTES E MÉTODO: De Janeiro de 1992 a Dezembro de 2002, 465 pacientes foram submetidos ao reparo de aneurismas da aorta abdominal. Destes, 13 eram aneurisma da aorta abdominal roto contido crônico (2,8%), que foram comparados a 26 controles nos quais a correção eletiva do aneurisma ocorreu imediatamente antes e após a correção do aneurisma da aorta abdominal roto contido crônico. RESULTADO: Não houve diferença entre os grupos com relação a idade, sexo, fatores de risco para aterosclerose, doenças associadas e cardiopatia isquêmica. Pacientes com aneurisma da aorta abdominal roto contido crônico apresentaram maior incidência de dor lombar (92,3% versus 3,9%;

Adenovirus-Mediated Transfer of the CFTR Gene to Lung of Nonhuman Primates: Biological Efficacy Study

Overview summary Recombinant adenoviruses hold tremendous promise for gene therapies of lung disease in cystic fibrosis (CF). An evaluation of the feasibility and safety of this technology in nonhuman primates is critical in the design of clinical protocols. In a series of two papers, Wilson and colleagues describe an extensive study in baboons designed to evaluate the feasibility and safety of direct instillation of CF transmembrane conductance regulator (CFTR)-expressing adenoviruses into the airway. This paper by Engelhardt et al., addresses the biological efficacy of E1-deleted adenoviruses for gene therapy of CF lung disease.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63146/1/hum.1993.4.6-759.pd
