A study to explore the use of orbital remote sensing to determine native arid plant distribution

The author has identified the following significant results. It is possible to determine, from ERTS imagery, native arid plant distribution. Using techniques of multispectral masking and extensive fieldwork, three native vegetation communities were defined and mapped in the Avra Valley study area. A map was made of the Yuma area with the aid of ground truth correlations between areas of desert pavement visible on ERTS images and unique vegetation types. With the exception of the Yuma soil-vegetation correlation phenomena, only very gross differentiations of desert vegetation communities can be made from ERTS data. Vegetation communities with obvious vegetation density differences such as saguaro-paloverde, creosote bush, and riparian vegetation can be separated on the Avra Valley imagery while more similar communities such as creosote bush and saltbush could not be differentiated. It is suggested that large differences in vegetation density are needed before the signatures of two different vegetation types can be differentiated on ERTS imagery. This is due to the relatively insignificant contribution of vegetation to the total radiometric signature of a given desert scene. Where more detailed information concerning the vegetation of arid regions is required, large scale imagery is appropriate

Family Adaptability and Cohesion Influences on Positive Health Outcomes for Adolescent and Young Adults Undergoing Stem Cell Transplant for Cancer

poster abstractStem cell transplant (SCT) is a physically and emotionally difficult experience for adolescents/young adults (AYA) with cancer. AYA undergoing SCT require high levels of support to deal with illness-related distress. Family adaptability and cohesion are key protective factors influencing AYA outcomes throughout the SCT treatment process. Research on the influences of family protective factors on SCT outcomes for AYA is minimal. Purposes of this secondary analysis are to: 1) longitudinally examine the trajectory of family adaptability/cohesion and well-being; 2) describe AYA perceived family adaptability/cohesion and well-being at each of 3 three time points; 3) describe relationships between adaptability, cohesion and well-being from each time point to all other subsequent time points; 4) examine the longitudinal influence of adaptability/cohesion on well-being. The Haase Resilience in Illness Model (RIM) that guides this study identifies two risk factors and five protective factors that influence resilience and quality of life outcomes. The study design was longitudinal, descriptive. The sample included 53 AYA, 11 to 24 years of age, undergoing SCT for cancer at 11 pediatric or adult hospitals. AYA completed measures on a secure web-based server immediately prior to, during, and 90 days post-SCT. The RIM-related variables family adaptability, cohesion, and well-being were measured by the Family Adaptability and Cohesion Scale (FACES II) and Index of Well-Being (IWB). Descriptive and correlational statistics were used to analyze the data. We found that improvement in adaptability/cohesion is not strongly associated with improvement in well-being from T2 to T1 or T3 to T1, but is statistical significance when compared between T3 to T2. It is necessary to understand how family adaptability/cohesion influences AYA uncertainty and symptoms, coping, derived meaning of illness, and resilience, in order to develop effective family-focused interventions that foster resilience outcomes

Research in Palliative and End-of-Life Communication and Training (RESPECT) Center: Year 3 2012-2013

poster abstractThe mission of the Research in Palliative and End-of-Life Communication and Training (RESPECT) Center is to build a collaborative, interdisciplinary scientific community of researchers and clinicians to work together to advance the science of communication in palliative and end-of-life care across the lifespan. Center Goals: • Accelerate the development of innovative descriptive and intervention research trials relevant to communication and decision-making in children, adolescents, adults, and elders with serious and/or life-threatening illness • Develop new community partnerships for translational science to enhance palliative and end-of-life care research and practice • Create mentorship opportunities for developing scholars who will become the next generation of productive, passionate palliative and end-of-life care researchers The RESPECT Center is comprised of 19 faculty, 3 post-doctoral trainees and 3 staff members. Faculty meet twice a month to review and provide feedback to support the development of ideas and submission of research grants. In the 2011-2012 funding year, RESPECT Center faculty submitted 11 grants and received over $7.9 million dollars in funding, representing an increase of 21 % from the previous year. Additionally, faculty collaborated on the dissemination of findings and published XX articles on palliative and end-of-life care. The Center’s Visiting Scholar Series has hosted visits by 7 nationally recognized experts to consult with faculty and share their expertise with the community. On March 1, 2013, the RESPECT Center hosted a one-day statewide conference to bring together researchers and clinicians in Carmel, Indiana. The conference entitled, Translating Research into Best Practice: Improving Palliative and End-of-life Care, was attended by approximately 150 participants from 45 organizations. Finally, the RESPECT Center awarded 5 pilot study grants to help researchers develop critically important pilot data and continues to mentor developing scholars interested in the science of communication in palliative and end-of-life care

On the proper reconstruction of complex dynamical systems spoilt by strong measurement noise

This article reports on a new approach to properly analyze time series of dynamical systems which are spoilt by the simultaneous presence of dynamical noise and measurement noise. It is shown that even strong external measurement noise as well as dynamical noise which is an intrinsic part of the dynamical process can be quantified correctly, solely on the basis of measured times series and proper data analysis. Finally real world data sets are presented pointing out the relevance of the new approach

A Systematic Literature Review of the Current State of Knowledge Related to Interventions for Bereaved Parents

Aims: The purpose of this systematic literature review is to describe the interventions for bereaved parents, evaluate intervention effectiveness through study methodology rigor, replicability, and theoretical foundations. Methods: We searched MEDLINE via PubMed (1966-2018), CINAHL (1937-present), PsycINFO (1887-present), and Embase (1947-present) using various search words and MeSH terms related to the study purpose. A blinded screening of title/abstract was performed, with conflicting inclusion decisions resolved through group discussions. Matrices for remaining articles were created and discussed among the team. The levels of evidence of the 9 records were rated from very low to high based on the Grading of Recommendations Assessment, Development, and Evaluation guidelines. Results: Our initial pool included 1025 articles. After the screening of titles/abstracts, 63 articles were retained for full-text reviews. Evaluated based on the inclusion/exclusion criteria, 9 records met the review criteria. Of the 9 records, 1 was graded as very low, 3 low, and 5 low to moderate. The interventions for bereaved parents varied from using single-model interventions such as expressive arts therapy and telephone support to multimodal interventions that combined resources (ie, peer support, resource packets, and health-care support). Only 1 study explicitly illustrated how its bereavement intervention was designed based on the proposed theoretical model. Conclusions: This review highlights the need for individualized, well-tested, and effective bereavement care interventions to support bereaved parents. In summary, the state of the science on interventions for bereaved parents is poor and much work needs to be done to effectively address the needs of bereaved parents, including both their physical and emotional health needs

Pilot testing a couples-focused intervention for mild cognitive impairment

The purpose of this pilot was to evaluate the acceptability, feasibility, and potential benefits of the multicomponent, Daily Enhancement of Meaningful Activity (DEMA) intervention, which was tailored to help couples facing mild cognitive impairment (MCI) work together to meet goals, remain engaged in meaningful activities, and adapt to changes over time. Using a single-group design, 10 individuals with MCI and their family caregivers were recruited to participate in the DEMA intervention over 6 biweekly sessions. Data were collected pre-and at 1 week and 3 months postintervention completion rates indicated the program and study procedures were well accepted. Qualitative and quantitative finding indicated positive trends in meaningful activity performance and maintenance of health-related outcomes, as well as high program satisfaction. The DEMA intervention is potentially promising but needs further testing in a randomized clinical trial

Transport of Bose-Einstein Condensates with Optical Tweezers

We have transported gaseous Bose-Einstein condensates over distances up to 44 cm. This was accomplished by trapping the condensate in the focus of an infrared laser and translating the location of the laser focus with controlled acceleration. Condensates of order 1 million atoms were moved into an auxiliary chamber and loaded into a magnetic trap formed by a Z-shaped wire. This transport technique avoids the optical and mechanical access constraints of conventional condensate experiments and creates many new scientific opportunities.Comment: 5 pages, 3 figure
