Victims\u27 Perceptions of Criminal Justice
This article considers the criminal justice system from the crime victim\u27s perspective. Victims are the people behind crime statistics. They are the individuals who suffer the injuries inflicted by criminals and who reveal the existence of crime when they report it. Victims are the key to apprehending criminals and the justification for the state\u27s subsequent prosecution, yet they are often the people we know least about
Urine metabolomic analysis to detect metabolites associated with the development of contrast induced nephropathy.
ObjectiveContrast induced nephropathy (CIN) is a result of injury to the proximal tubules. The incidence of CIN is around 11% for imaging done in the acute care setting. We aim to analyze the metabolic patterns in the urine, before and after dosing with intravenous contrast for computed tomography (CT) imaging of the chest, to determine if metabolomic changes exist in patients who develop CIN.MethodsA convenience sample of high risk patients undergoing a chest CT with intravenous contrast were eligible for enrollment. Urine samples were collected prior to imaging and 4 to 6 hours post imaging. Samples underwent gas chromatography/mass spectrometry profiling. Peak metabolite values were measured and data was log transformed. Significance analysis of microarrays and partial least squares was used to determine the most significant metabolites prior to CT imaging and within subject. Analysis of variance was used to rank metabolites associated with temporal change and CIN. CIN was defined as an increase in serum creatinine level of ⼠0.5 mg/dL or ⼠25% above baseline within 48 hours after contrast administration.ResultsWe sampled paired urine samples from 63 subjects. The incidence of CIN was 6/63 (9.5%). Patients without CIN had elevated urinary citric acid and taurine concentrations in the pre-CT urine. Xylulose increased in the post CT sample in patients who developed CIN.ConclusionDifferences in metabolomics patterns in patients who do and do not develop CIN exist. Metabolites may be potential early identifiers of CIN and identify patients at high-risk for developing this condition prior to imaging
Shared decision making in patients with low risk chest pain: prospective randomized pragmatic trial.
OBJECTIVE: To compare the effectiveness of shared decision making with usual care in choice of admission for observation and further cardiac testing or for referral for outpatient evaluation in patients with possible acute coronary syndrome.
DESIGN: Multicenter pragmatic parallel randomized controlled trial.
SETTING: Six emergency departments in the United States.
PARTICIPANTS: 898 adults (aged \u3e17 years) with a primary complaint of chest pain who were being considered for admission to an observation unit for cardiac testing (451 were allocated to the decision aid and 447 to usual care), and 361 emergency clinicians (emergency physicians, nurse practitioners, and physician assistants) caring for patients with chest pain.
INTERVENTIONS: Patients were randomly assigned (1:1) by an electronic, web based system to shared decision making facilitated by a decision aid or to usual care. The primary outcome, selected by patient and caregiver advisers, was patient knowledge of their risk for acute coronary syndrome and options for care; secondary outcomes were involvement in the decision to be admitted, proportion of patients admitted for cardiac testing, and the 30 day rate of major adverse cardiac events.
RESULTS: Compared with the usual care arm, patients in the decision aid arm had greater knowledge of their risk for acute coronary syndrome and options for care (questions correct: decision aid, 4.2 v usual care, 3.6; mean difference 0.66, 95% confidence interval 0.46 to 0.86), were more involved in the decision (observing patient involvement scores: decision aid, 18.3 v usual care, 7.9; 10.3, 9.1 to 11.5), and less frequently decided with their clinician to be admitted for cardiac testing (decision aid, 37% v usual care, 52%; absolute difference 15%; P
CONCLUSIONS: Use of a decision aid in patients at low risk for acute coronary syndrome increased patient knowledge about their risk, increased engagement, and safely decreased the rate of admission to an observation unit for cardiac testing.Trial registration ClinicalTrials.gov NCT01969240
Geography of Spring Landbird Migration Through Riparian Habitats in Southwestern North America
Migration stopover resources, particularly riparian habitats, are critically important to landbirds migrating across the arid southwestern region of North America. To explore the effects of species biogeography and habitat affinity on spring migration patterns, we synthesized existing bird abundance and capture data collected in riparian habitats of the borderlands region of the U.S. and Mexico. We determined the importance of geographic factors (longitude and latitude) in explaining variation in abundances and capture rates of 32 long-distance and three short-distance migrant species. Abundances and capture rates of 13 and 11 species, respectively, increased with increasing longitude, and four species\u27 abundance and capture rates decreased with increasing longitude. Riparian associates, but not nonriparian species, were more abundant in western sites. Their abundance patterns were only weakly influenced by species biogeography. In contrast, biogeography did influence abundance patterns of nonriparian birds, suggesting that they choose the shortest, most direct route between wintering and breeding areas. We hypothesize that riparian obligate birds may, to some degree, adjust their migration routes to maximize time spent in high-quality riparian zones, but they are able to find suitable habitat opportunistically when crossing more hostile landscapes. In contrast, nonriparian birds adhere more closely to a hierarchical model in which the migratory route is determined by biogeographic constraints. Conservation of riparian habitats is necessary to meet future habitat stopover requirements of many western Neotropical migrant birds. We advocate a coordinated research effort to further elucidate patterns of distribution and habitat use so that conservation activities can be focused effectively

Purpose:
The interprofessional teamâs role in end of life care provides a unique opportunity for an educational simulation. Novel ways to teach this content to a large number of students were needed. This research evaluated a palliative care interprofessional educational activity for healthcare students from six disciplines using an in-person movie/discussion format.
Methods:
Healthcare provider assessment visits and a death scene were pilot tested in actual simulations using twenty four students with standardized patients portraying a patient with ALS and his husband. Scripts were written from recordings of these simulations and were used in the dialogue of the movie which had standardized patient actors playing the patient, husband, sister and the student healthcare providers. The movie portrayed a patient with ALS and his husband in five scenes: assessment of patient and family needs by nursing, physical therapy, social work and speech language pathology; and a death scene. The movie was then edited to be used for discussion by large student groups.
An evaluation survey was developed with 14 questions scored on a Likert scale and related to Interprofessional Competency Domains of 1. Values/Ethics, 2. Roles/Responsibilities, 3. Interprofessional communication, and 4. Teams/teamwork. These competencies provided a structure for the evaluation questions, and a review by faculty in each discipline also provided content validity. Reliability of the survey instrument was not tested or established. Graduate nurse practitioner, medical, communication sciences and disorders, social work and physical therapy students as well as undergraduate nursing students participated together in end of life movie discussions in four sessions held in a classroom equipped with tables of six.
Survey responses were compared across disciplines and across the four interprofessional competency domains using a Chi-square test and adjusting for multiple comparisons. Significant differences were established at p
Results:
Student evaluations of the end of life simulations were consistently positive. Eighty percent of the participants (n=162) strongly agreed that they recognize the necessity of utilizing a healthcare team when providing care for patients at the end of life. All participants agreed that they would continue to forge relationships with other healthcare professionals to improve care for elders. Physical therapy students were consistently had the most positive responses; however, significant differences were only observed in three of the 14 questions. There were no significant differences between disciplines across the four interprofessional competency domains. A summary of qualitative data from the open ended questions will be also be presented.
Conclusion:
Interprofessional end of life care can be simulated in a carefully planned activity. The value of the experience was expressed by all students. Nurse practitioner students valued being able to practice supervising a palliative care team and facilitating the team discussion. Other students appreciated a safe place to discuss how to care for a dying patient and their family. Regarding the evaluation, small sample sizes in some disciplines may have limited the ability to detect significant differences between groups. Production of a movie and the discussion of the different scenes helped lower the cost of the simulation and scale up the activity for use with large groups of students. Interprofessional education requires innovative pedagogy that must be evaluated and disseminated. Consistent evaluation of interprofessional practice competency domains must be included in all educational activities
Criteria for the use of omics-based predictors in clinical trials.
The US National Cancer Institute (NCI), in collaboration with scientists representing multiple areas of expertise relevant to 'omics'-based test development, has developed a checklist of criteria that can be used to determine the readiness of omics-based tests for guiding patient care in clinical trials. The checklist criteria cover issues relating to specimens, assays, mathematical modelling, clinical trial design, and ethical, legal and regulatory aspects. Funding bodies and journals are encouraged to consider the checklist, which they may find useful for assessing study quality and evidence strength. The checklist will be used to evaluate proposals for NCI-sponsored clinical trials in which omics tests will be used to guide therapy
Optical Excitations and Field Enhancement in Short Graphene Nanoribbons
The optical excitations of elongated graphene nanoflakes of finite length are
investigated theoretically through quantum chemistry semi-empirical approaches.
The spectra and the resulting dipole fields are analyzed, accounting in full
atomistic details for quantum confinement effects, which are crucial in the
nanoscale regime. We find that the optical spectra of these nanostructures are
dominated at low energy by excitations with strong intensity, comprised of
characteristic coherent combinations of a few single-particle transitions with
comparable weight. They give rise to stationary collective oscillations of the
photoexcited carrier density extending throughout the flake, and to a strong
dipole and field enhancement. This behavior is robust with respect to width and
length variations, thus ensuring tunability in a large frequency range. The
implications for nanoantennas and other nanoplasmonic applications are
discussed for realistic geometries
Criteria for the use of omics-based predictors in clinical trials: explanation and elaboration
Abstract
High-throughput âomicsâ technologies that generate molecular profiles for biospecimens have been extensively used in preclinical studies to reveal molecular subtypes and elucidate the biological mechanisms of disease, and in retrospective studies on clinical specimens to develop mathematical models to predict clinical endpoints. Nevertheless, the translation of these technologies into clinical tests that are useful for guiding management decisions for patients has been relatively slow. It can be difficult to determine when the body of evidence for an omics-based test is sufficiently comprehensive and reliable to support claims that it is ready for clinical use, or even that it is ready for definitive evaluation in a clinical trial in which it may be used to direct patient therapy. Reasons for this difficulty include the exploratory and retrospective nature of many of these studies, the complexity of these assays and their application to clinical specimens, and the many potential pitfalls inherent in the development of mathematical predictor models from the very high-dimensional data generated by these omics technologies. Here we present a checklist of criteria to consider when evaluating the body of evidence supporting the clinical use of a predictor to guide patient therapy. Included are issues pertaining to specimen and assay requirements, the soundness of the process for developing predictor models, expectations regarding clinical study design and conduct, and attention to regulatory, ethical, and legal issues. The proposed checklist should serve as a useful guide to investigators preparing proposals for studies involving the use of omics-based tests. The US National Cancer Institute plans to refer to these guidelines for review of proposals for studies involving omics tests, and it is hoped that other sponsors will adopt the checklist as well.http://deepblue.lib.umich.edu/bitstream/2027.42/134536/1/12916_2013_Article_1104.pd
BUILDING A SUSTAINABLE NETWORK OF DROUGHT COMMUNITIES
The first step in managing large-scale (national) collaborations and networks is to consider and address how a group and a potential partnership may match up (Luther, 2005). To explore this concept and many other collaborative concepts, the National Integrated Drought Information System (NIDIS) hosted a workshop, âBuilding a Sustainable Network of Drought Communities,â which was facilitated by the National Drought Mitigation Center (NDMC) in Chicago, IL, June 8-9, 2011.
The workshop explored current examples of good communication and lessons learned within the realm of drought planning in order to address a future NIDIS Engaging Preparedness Communities (EPC) working group that is solution-focused and collaborative. With the diversity and experience of the participants at this meeting, a wealth of good practices or lessons learned in drought planning, preparedness, and general stakeholder engagement set the pathway for building a sustainable community of drought practitioners.
In his opening remarks, NIDIS Director Roger Pulwarty noted that adaptive institutions can show robustness in the following ways: Levels of alertnessâmonitoring the external world for early warning signs that key assumptions are likely to verify/fail and a commitment to rigorous monitoring of performance; Agilityâthe ability to react to early warning signs of problems or opportunities; flow of knowledge across components, and to adjust strategies and tactics rapidly to meet changes in the environment; and Alignmentâthe ability to align the whole organization (and partners) to its mission-policies and practices that give rise to failures/successes. Through an interactive workshop format that used Appreciative Inquiry (framing breakout sessions on success), the group was able to effectively discuss topics such as: ⢠Integrating Planning Efforts ⢠Planning Under Uncertainty ⢠Evaluating, Assessing, and Updating Drought Plans ⢠Leveraging Resources for Risk Management ⢠Implementing Plans and Planning Information ⢠Synthesizing Success Stories and Lessons Learned ⢠Creating a Sustainable Network of Drought Professionals
The most common themes resulting from the workshop included: ⢠Importance of networking and collaborationâthis is a necessity. Figuring out how to make it seamless is the main goal that the NIDIS EPC Community should foster. Good communication is the key among the drought practitioners and their stakeholders. ⢠Celebrate successâin this future drought network, successes related to drought efforts should be highlighted within the community and to the public. This will help drive future positive interactions and collaborations. It also gives the community a sense of pride. ⢠âStakeholder Buy-Inââwhy should stakeholders stay engaged in an ongoing drought community? Especially when there is no drought? Again, good communication and collaborations with other multi-hazard, sustainability, and natural resources planning efforts will help keep drought a priority. ⢠Economic, environmental, and social aspects of planning for droughtâthese should always be considered. This was a recurrent theme in the workshop. ⢠Planners should not âreinvent the wheelââplanners involved in climate adaptation work can and should reference the best drought planning resources and case studies to help them incorporate drought in their overall planning efforts. ⢠âHave a plan for the planââhow and who will make it happen? What kind of leadership is needed within the NIDIS EPC community to track its progress and success? ⢠Sharing of resourcesâas budgets become slimmer, a central location of available resources and the sharing of resources in the area of drought preparedness and mitigation is necessary. Communication regarding these potential resources should also be integrated into this NIDIS EPC community.
Since the occurrence of the workshop, several EPC-related activities have taken place, including a webinar in December 2011. This workshop report and additional EPC updates will be placed on the U.S. Drought portal (www.drought.gov). Currently, the American Planning Association (APA), NIDIS and the NDMC are collaborating to produce a Planning Advisory Service (PAS) Report to connect drought mitigation resources with the planning practices of local, regional, tribal and state governments. This builds on the work of the APAâs Hazard Planning Center, which produced a similar PAS Report (sponsored by FEMA) on how to integrate multi-hazard planning into planning practices. In May 2012: The APAâs drought planning project webpage went live and can be found at: http://www.planning.org/research/drought/index.ht
