The objective of this study was to develop a one-page (1-page) prescription drug information leaflet (PILs) and assess their impact on the information processing variables, across 2 levels of patient involvement. One-page PILs were developed using cognitive principles to lower mental effort and improve comprehension. An experimental, 3 × 2 repeated measures study was conducted to determine the impact of cognitive effort, manipulated using leaflet type on comprehension across 2 levels (high/low) of patient involvement. Adults (≥18 years) in a university setting in Houston were recruited for the study. Each participant was exposed to 3 different types of prescription drug information leaflet (the current practice, preexisting 1-page text-only, and 1-page PILs) for the 3 drugs (Celebrex, Ventolin HFA, Prezista) for a given involvement scenario. A prevalidated survey instrument was used to measure product knowledge, attitude toward leaflet, and intention to read. Multivariate analysis of variance indicated significant positive effect of cognitive effort, involvement, and their interaction effect across all measured variables. Mean scores for product knowledge, attitude toward leaflet, and intention to read were highest for PILs ( P < .001), indicating that PILs exerted lowest cognitive effort. Univariate and post hoc analysis indicate that product knowledge significantly increases with high involvement. Patients reading PILs have higher comprehension compared with the current practice and text-only prototype leaflets evaluated. Higher levels of involvement further improve participant knowledge about the drug, increase their intention to read the leaflet, and change their attitude toward the leaflet. Implementation of PILs would improve information processing for consumers by reducing their cognitive effort.

Emerging Plasmodium vivax resistance to chloroquine in South America: an overview
Gonçalves, Lígia Antunes; Cravo, Pedro; Ferreira, Marcelo Urbano
2014-01-01
The global emergence of Plasmodium vivax strains resistant to chloroquine (CQ) since the late 1980s is complicating the current international efforts for malaria control and elimination. Furthermore, CQ-resistant vivax malaria has already reached an alarming prevalence in Indonesia, East Timor and Papua New Guinea. More recently, in vivo studies have documented CQ-resistant P. vivax infections in Guyana, Peru and Brazil. Here, we summarise the available data on CQ resistance across P. vivax-endemic areas of Latin America by combining published in vivo and in vitro studies. We also review the current knowledge regarding the molecular mechanisms of CQ resistance in P. vivax and the prospects for developing and standardising reliable molecular markers of drug resistance. Finally, we discuss how the Worldwide Antimalarial Resistance Network, an international collaborative effort involving malaria experts from all continents, might contribute to the current regional efforts to map CQ-resistant vivax malaria in South America.

History of United States Army physical fitness and physical readiness training.
Knapik, Joseph J; East, Whitfield B
2014-01-01
This article traces the history of US Army physical fitness assessments from the first test developed for Cadets at the US Military Academy in 1858 through efforts to revise the current Army Physical Fitness Test (APFT). The first "Individual Efficiency Test" (1920) for all Soldiers consisted of a 100-yard run, running broad jump, wall climb, hand grenade throw, and obstacle course. The first scientific efforts involved testing of 400 Soldiers and a factor analysis of 25 individual test items. In 1944, this resulted in a 7-item test (pull-up, burpee, squat jump, push-up, man-carry, sit-up and 300-yard run) with a 100-point scoring system. In 1943, women were encouraged to take a "self-assessment" consisting of push-ups, bent knee sit-ups, wing lifts, squat thrusts, running, and a stork stand. In 1946, age-adjusted standards were introduced and in 1965 semiannual fitness assessments were mandated. The number of tests proliferated in the 1969-1973 period with 7 separate assessments. The current APFT consisting of push-ups, sit-ups, and a 2-mile run was introduced in 1980 and alternative tests for those with physical limitations in 1982. Current efforts to revise the assessment involve systematic literature reviews and validating the relationship between test items and common Soldiering tasks.

It is seldom technical issues which impede the process of eliciting software requirements. The involvement of multiple stakeholders usually leads to conflicts and therefore the need of conflict detection and resolution effort is crucial. This paper presents a conceptual model to further improve current efforts. Hence, this paper forwards an improved conceptual model to assist the conflict detection and resolution effort which extends the model ability and improves overall performance. The significant of the new model is to empower the automation of conflicts detection and its severity level with rule-based reasoning.
A haphazard reading of McHugh and Barlow (2010).

2010-12-01
Replies to comments on Do haphazard reviews provide sound directions for dissemination efforts? (see record 2010-24768-012) by Eileen Gambrill and Julia H. Littell on the current authors' article The dissemination and implementation of evidence-based psychological treatments: A review of current efforts (see record 2010-02208-010) by Kathryn R. McHugh and David H. Barlow. In their commentary, Gambrill and Littell (2010, this issue) suggested that we provided misleading guidance on the selection of treatments for dissemination in our recent article (McHugh & Barlow, February- March 2010) on the dissemination and implementation of evidence-based treatments. These authors misread our article as an affirmation of the evidence base of the treatments involved in the dissemination and implementation efforts we described. In fact, we explicitly disclaimed in the third paragraph that "we do not revisit controversies surrounding the identification or appropriateness of [evidence-based psychological treatments] . . . rather, we focus on the status and adequacy of [dissemination and implementation] efforts currently under way (McHugh & Barlow, 2010, p. 73). Thus, our review was not intended as a guideline for which treatments to disseminate, nor was it a thorough review of the evidence base for the treatments included in the efforts we reviewed. We chose several programs for illustrative purposes as representative efforts from three general domains: national, state, and investigator initiated.

Child maltreatment is a worldwide social problem that receives considerable attention. However, prevention efforts remain rare, allowing the phenomenon to continue and spread. The aim of the current article is to systematically review evidence-based prevention efforts that address schools and families as key stakeholders for preventing child maltreatment. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a thorough literature review revealed that only five programs matched the inclusion criteria for the current article. These programs were analyzed for several domains, including level of prevention, target population, participants, and the programs' outcomes. The current review highlights the urgent needs to develop, modify, and further evaluate prevention programs for child maltreatment in the context of the ecological model. More specifically, it illuminates the need to create and champion programs that enhance the collaboration between families and schools, both of which are key stakeholders within the phenomenon of child maltreatment. Collaboration between policymakers, researchers, and practitioners should guide future efforts by promoting cultural adaptation to such programs and by integrating children's perceptions to improve these efforts and to benefit everyone involved.
Rates of traumatization and psychopathology in criminal justice-involved women.
Salina, Doreen D; Figge, Caleb; Ram, Daphna; Jason, Leonard A
2017-01-01
Prior research has consistently found disproportionate rates of traumatization and psychopathology in criminal justice-involved women. The current study aimed to characterize rates of traumatization, psychopathology, and diagnostic comorbidity in women involved with the justice system. Furthermore, this study examined the role of posttraumatic stress symptoms in the association between traumatic events and levels of self-esteem. Participants were 185 women from the Chicagoland area with current or previous (past 2 years) involvement with the criminal justice system. Results confirmed disproportionate rates of trauma experiences and psychopathology in this population, and logistic regression analyses indicated that rates of traumatization predicted diagnostic comorbidity. Analyses indicated an indirect effect of posttraumatic stress in the association between traumatic experiences and self-esteem. Findings highlight the importance of assessing and targeting both trauma experiences and posttraumatic stress in justice-involved women to optimize prevention and intervention efforts.

Development of breeding colonies of rhesus macaques (Macaca mulatta) that are specific pathogen-free (SPF) for rhesus cytomegalovirus (RhCMV) is relatively straightforward and requires few modifications from current SPF programs. Infants separated from the dam at or within a few days of birth and cohoused with similarly treated animals remain RhCMV seronegative indefinitely, provided they are never directly or indirectly exposed to a RhCMV-infected monkey. By systematically cohousing seronegative animals into larger social cohorts, breeding populations of animals SPF for RhCMV can be established. The additional costs involved in expanding the current definition of SPF status to include RhCMV are incremental compared with the money already being spent on existing SPF efforts. Moreover, the large increase in research opportunities available for RhCMV-free animals arguably would far exceed the development costs. Potential new areas of research and further expansion of existing research efforts involving these newly defined SPF animals would have direct implications for improvements in human health.

Male involvement is crucial to female contraceptive use. This study examined how male knowledge and cultural perceptions of modern female contraceptives influence involvement in contraceptive use. A cross-sectional survey of 389 men from Ayete, Nigeria was used to regress a continuous male involvement score on demographic variables, knowledge of at least one method of modern female contraception and a scored male perception variable using Ordinary Least Squares regression. Controlling for perception, the knowledge of at least one method of modern female contraception was not significantly associated with a change in male involvement (p=0.264). Increasing positive perception was associated with higher male involvement scores (p=0.001). Higher educated males, those with a current desire to have children and males whose partners were currently using a method had greater male involvement scores (p<0.05). Policy and intervention efforts should be focused on changing cultural perceptions, in addition to providing in-depth knowledge of contraceptive methods.

Enthalpy measurement of coal-derived liquids. Technical progress report, August-October 1982
DOE Office of Scientific and Technical Information (OSTI.GOV)
Kidnay, A.J.; Yesavage, V.F.
The correlational effort on the coal syncrudes and model compounds has been proceeding along two fronts. The first involves experimental work on a correlating factor for association in the liquids and the second involves an investigation of the modeling capabilities of cubic equations of state. The first area of investigation is the experimental measurement of a correlating factor for assocition in coal liquids. The procedure involves molecular weight measurement by freezing point depression. To facilitate these measurements, a simple Beckman freezing point depression apparatus is being currently modified to increase the accuracy, speed, and ease of measurement. The second areamore » of effort has involved establishing a set of cubic equations of state which can adequately model the enthalpy departures of quinoline and m-cresol. To this effort, a number of standard and association specific equations of state have been tested against a data base of previously measured enthalpy departures of m-cresol and quinoline. It has been found that these equations do quantitatively a poor job on m-cresol and quinoline. These problems are probably due to the highly polar nature of m-cresol and to a lesser extent quinoline, and to the poor quality of critical parameters for quinoline.« less

Complex space monofilar approximation of diffraction currents on a conducting half plane
NASA Technical Reports Server (NTRS)
Lindell, I. V.
1987-01-01
Simple approximation of diffraction surface currents on a conducting half plane, due to an incoming plane wave, is obtained with a line current (monofile) in complex space. When compared to an approximating current at the edge, the diffraction pattern is seen to improve by an order of magnitude for a minimal increase of computation effort. Thus, the inconvient Fresnel integral functions can be avoided for quick calculations of diffracted fields and the accuracy is good in other directions than along the half plane. The method can be applied to general problems involving planar metal edges.

Investigation of Next-Generation Earth Radiation Budget Radiometry
NASA Technical Reports Server (NTRS)
Coffey, Katherine L.; Mahan, J. R.
1999-01-01
The current effort addresses two issues important to the research conducted by the Thermal Radiation Group at Virginia Tech. The first research topic involves the development of a method which can properly model the diffraction of radiation as it enters an instrument aperture. The second topic involves the study of a potential next-generation space-borne radiometric instrument concept. Presented are multiple modeling efforts to describe the diffraction of monochromatic radiant energy passing through an aperture for use in the Monte-Carlo ray-trace environment. Described in detail is a deterministic model based upon Heisenberg's uncertainty principle and the particle theory of light. This method is applicable to either Fraunhofer or Fresnel diffraction situations, but is incapable of predicting the secondary fringes in a diffraction pattern. Also presented is a second diffraction model, based on the Huygens-Fresnel principle with a correcting obliquity factor. This model is useful for predicting Fraunhofer diffraction, and can predict the secondary fringes because it keeps track of phase. NASA is planning for the next-generation of instruments to follow CERES (Clouds and the Earth's Radiant Energy System), an instrument which measures components of the Earth's radiant energy budget in three spectral bands. A potential next-generation concept involves modification of the current CERES instrument to measure in a larger number of wavelength bands. This increased spectral partitioning would be achieved by the addition of filters and detectors to the current CERES geometry. The capacity of the CERES telescope to serve for this purpose is addressed in this thesis.

Esophageal atresia and tracheoesophageal fistula (EA/TEF) are major congenital malformations affecting 1:3500 live births. Current research efforts are focused on understanding the etiology of these defects. We describe well-known animal models, human syndromes, and associations involving EA/TEF, indicating its etiologically heterogeneous nature. Recent advances in genotyping technology and in knowledge of human genetic variation will improve clinical counseling on etiologic factors. This review provides a clinical summary of environmental and genetic factors involved in EA/TEF. PMID:20425471

Gratitude is an important aspect of human sociality, which benefits mental health and interpersonal relationships. Thus, elucidating the neural mechanism of gratitude, which is only now beginning to be investigated, is important. To this end, this study specifies the medial prefrontal cortex (mPFC) involved in the gratitude of heterogeneous individuals using the transcranial direct current stimulation (tDCS) technique. Previous neural studies have shown the involvement of mPFC in social cognition and value evaluation, which are closely related to gratitude. However, the causal relationship between this neural area and gratitude has not been fully examined and the effect of individual social heterogeneity has been ignored. Meanwhile, behavioral economics studies have proposed that the abilities of employees in the labor market would affect their gratitude and emotional response. Thus, we designed an experiment based on gift exchange game to investigate the relationship between mPFC and gratitude of heterogeneous employees. Before the experiment, participants were asked to perform self-cognition of their abilities through an appropriately difficult task. We then used the effort of participants to imply their gratitude and analyzed the effort levels of employees with different abilities under anodal, cathodal, and sham stimulations. The results showed that employees under anodal stimulation were significantly likely to increase their effort than those under sham stimulation, and employees under cathodal stimulation ranked at the bottom of the list. Moreover, the effort levels of low-ability employees were obviously higher than those of high-ability employees. The cathodal stimulation of mPFC significantly reduced the effort levels of low-ability employees, whereas its anodal tDCS stimulation increased the effort levels of high-ability employees. These outcomes verify the relationship between mPFC and gratitude using tDCS and provided one of the first instances of neural evidence for the incentive mechanism design in the labor market to a certain extent.

To this end, this study specifies the medial prefrontal cortex (mPFC) involved in the gratitude of heterogeneous individuals using the transcranial direct current stimulation (tDCS) technique. Previous neural studies have shown the involvement of mPFC in social cognition and value evaluation, which are closely related to gratitude. However, the causal relationship between this neural area and gratitude has not been fully examined and the effect of individual social heterogeneity has been ignored. Meanwhile, behavioral economics studies have proposed that the abilities of employees in the labor market would affect their gratitude and emotional response. Thus, we designed an experiment based on gift exchange game to investigate the relationship between mPFC and gratitude of heterogeneous employees. Before the experiment, participants were asked to perform self-cognition of their abilities through an appropriately difficult task. We then used the effort of participants to imply their gratitude and analyzed the effort levels of employees with different abilities under anodal, cathodal, and sham stimulations. The results showed that employees under anodal stimulation were significantly likely to increase their effort than those under sham stimulation, and employees under cathodal stimulation ranked at the bottom of the list. Moreover, the effort levels of low-ability employees were obviously higher than those of high-ability employees. The cathodal stimulation of mPFC significantly reduced the effort levels of low-ability employees, whereas its anodal tDCS stimulation increased the effort levels of high-ability employees. These outcomes verify the relationship between mPFC and gratitude using tDCS and provided one of the first instances of neural evidence for the incentive mechanism design in the labor market to a certain extent.

Background: The concept of a public-private partnership (PPP) has been proposed as a potential model for providing education services besides public finance and public delivery. The present study was conducted to survey the current practices of Private-Public Partnership (PPP) in health education in Udaipur city, Rajasthan, India. Methods: A questionnaire survey was conducted among organizations involved exclusively and actively in health education in Udaipur city, Rajasthan, India. The pretested self designed structured questionnaire consisted of 21 items pertaining to the current practices of private-public partnership (PPP) in health education. Descriptive statistics were used to describe the data. Results: On the basis of inclusion criteria, 50 personnel from 2 private dental colleges, 1 private medical college, 2 Non Government Organizations (NGOs) and 1 health museum were selected. Only 15 (30%) of participants agreed that they have a written reference policy that outlines the services they provide to the general public. Regarding the collection of health education materials available, majority 35 (70%) had printed books followed by audio visual (AV) materials (slides, videos, audio cassettes) [22 (44%)]. 35 (70%) of participants reported that they loan only pamphlets and broachers to the public. Thirty four (68%) of participants provide information about oral health. Only 23 (46%) of participants reported that their institution/organization undergo periodic evaluation. Conclusions: Results of this survey show that that most of the PPP were involved in delivering health education, mostly concentrated on general health. Only few of them were involved in oral health education. The role of PPP in health education is integral to the effort of promoting a healthier population. This effort continues the trend and broadens the scope of involvement for further studies. PMID:24130954

The Andean Regional Office of Astronomy for Development (ROAD) is a new effort in South America to serve several goals in astronomical development. Six countries (Bolivia, Colombia, Chile, Ecuador, Perú and Venezuela) will work together, representing a common language block in the Andean region and focusing on develop strategies to strengthen the professional research, education and popularization of astronomy. Our current Working Structure comprises a ROAD Coordinator and Coordinators per Task Force, as well as Organizing Committees, Collaborators and Volunteers.The participating institutions of this new ROAD have been involved in many projects involving each of the current OAD’s Task Forces: research, schools and children and public, exploring educational activities/material to be shared among the Andean countries, standardizing the knowledge and creating inspirational experiences. We expect to generate many efforts in order to bring a more homogeneous activity in each Andean country, taking into account the special role of Chile in global astronomy, due to its great conditions for astronomy and the involvement of many professional observatories, universities and astronomy institutions.Our current (and upcoming) most relevant activities includes: Andean Schools on Astronomy, Andean Graduate Program and Massive Open Online Courses (TF1); Virtual Training Sessions and Teaching material for the visually impaired students; Annual TF2 meeting to gather all the collaborators (TF2); Development for planetariums and Communicating Astronomy with the Public (TF3). The Andean region, in the other hand, will also be involved in at least two important events: the CAP Meeting in May 2016 and the XV LARIM in October 2016 (both in Colombia); and Chile will bid to host the XXXI IAU GA in 2021, with the aim of show the great advances in astronomical development from the Andean region and South America.
Brain Stimulation Over the Frontopolar Cortex Enhances Motivation to Exert Effort for Reward.
Soutschek, Alexander; Kang, Pyungwon; Ruff, Christian C; Hare, Todd A; Tobler, Philippe N
2018-07-01
Loss of motivation is a characteristic feature of several psychiatric and neurological disorders. However, the neural mechanisms underlying human motivation are far from being understood. Here, we investigate the role that the frontopolar cortex (FPC) plays in motivating cognitive and physical effort exertion by computing subjective effort equivalents. We manipulated neural processing with transcranial direct current stimulation targeting the FPC while 141 healthy participants decided whether or not to engage in cognitive or physical effort to obtain rewards. We found that brain stimulation targeting the FPC increased the amount of both types of effort participants were willing to exert for rewards. Our findings provide important insights into the neural mechanisms involved in motivating effortful behavior. Moreover, they suggest that considering the motivation-related activity of the FPC could facilitate the development of treatments for the loss of motivation commonly seen in psychiatric and other neurological disorders.

Davis, Matthew C.; Rocque, Brandon G.; Singhal, Ash; Ridder, Tom; Pattisapu, Jogi V.; Johnston, James M.
2017-01-01
Object Neurosurgical services are increasingly recognized as essential components of surgical care worldwide. Degree of interest among neurosurgeons regarding international work, and barriers to involvement in global neurosurgical outreach, are largely unexplored. We distributed a survey to members of the AANS/CNS Joint Section on Pediatric Neurosurgery to assess the state of global outreach among its members and identify barriers to involvement. Methods An internet-based questionnaire was developed by the International Education Subcommittee of the AANS/CNS Joint Section on Pediatric Neurosurgery, and distributed to pediatric neurosurgeons via the AANS/CNS Joint Section email contact list. Participants were surveyed on involvement in global neurosurgical outreach, geographic location, nature of participation, and barriers to further involvement. Results A 35.3% response rate was obtained, with 116 respondents completed the survey. 61% performed or taught neurosurgery in a developing country, 49% traveling at least annually. Africa was the most common region (54%), followed by South America (30%), through 29 separate organizing entities. Hydrocephalus was the most commonly treated condition (88%), followed by spinal dysraphism (74%) and tumor (68%). Most respondents obtained follow-up through communication from local surgeons (77%). 71% believed the international experience improved their practice, and 74% were very or extremely interested in working elsewhere. Interference with current practice (61%), cost (44%), and difficulty identifying international partners (43%) were the most commonly cited barriers to participation. Conclusion Any coordinated effort to expand global neurosurgical capacity begins with appreciation for the current state of outreach efforts. Increasing participation in global outreach will require addressing both real and perceived barriers to involvement. Creation and curation of a centralized online database of ongoing projects to facilitate coordination and involvement may be beneficial. PMID:28524788

Family involvement is recognized as a critical element of service planning for children's mental health, welfare and education. For the juvenile justice system, however, parents' roles in this system are complex due to youths' legal rights, public safety, a process which can legally position parents as plaintiffs, and a historical legacy of blaming parents for youth indiscretions. Three recent national surveys of juvenile justice-involved parents reveal that the current paradigm elicits feelings of stress, shame and distrust among parents and is likely leading to worse outcomes for youth, families and communities. While research on the impact of family involvement in the justice system is starting to emerge, the field currently has no organizing framework to guide a research agenda, interpret outcomes or translate findings for practitioners. We propose a research framework for family involvement that is informed by a comprehensive review and content analysis of current, published arguments for family involvement in juvenile justice along with a synthesis of family involvement efforts in other child-serving systems. In this model, family involvement is presented as an ascending, ordinal concept beginning with (1) exclusion, and moving toward climates characterized by (2) information-giving, (3) information-eliciting and (4) full, decision-making partnerships. Specific examples of how courts and facilities might align with these levels are described. Further, the model makes predictions for how involvement will impact outcomes at multiple levels with applications for other child-serving systems.
Cooperative efforts by industry and government to develop geothermal resources

Butler, D. R.
1974-01-01
The Federal government's current plans for participation in the geothermal field appear to affect four major areas of interest: (1) resources exploration and assessment, (2) resources utilization projects, (3) advanced research and technology, and (4) environmental, legal, and institutional research. Private industry is also actively involved in these same areas of interest. Because of lack of coordination and communication between the private and public sector, it appears that there will be considerable duplication of effort, and, in some cases, serious conflict. It is also likely that this lack of coordination and communication may result in lack of effort in some key areas. Close coordination and communication between government and industry may resolve some of the major problems that are clearly evident.

This paper is a survey of the waste minimization efforts of industries outside of aerospace for possible applications in the manufacture of solid rocket motors (SRM) for NASA. The Redesigned Solid Rocket Motor (RSRM) manufacturing plan was used as the model for processes involved in the production of an SRM. A literature search was conducted to determine the recycling, waste minimization, and waste treatment methods used in the commercial sector that might find application in SRM production. Manufacturers, trade organizations, and professional associations were also contacted. Waste minimization efforts for current processes and replacement technologies, which might reduce the amount or severity of the wastes generated in SRM production, were investigated. An overview of the results of this effort are presented in this paper.

Heinbockel, J. H.; Clowdsley, M. S.
1998-01-01
Current research on the Grant involves the development of a multigroup method for the calculation of low energy evaporation neutron fluences associated with the Boltzmann equation. This research will enable one to predict radiation exposure under a variety of circumstances. Knowledge of radiation exposure in a free-space environment is a necessity for space travel, high altitude space planes and satellite design. This is because certain radiation environments can cause damage to biological and electronic systems involving both short term and long term effects. By having apriori knowledge of the environment one can use prediction techniques to estimate radiation damage to such systems. Appropriate shielding can be designed to protect both humans and electronic systems that are exposed to a known radiation environment. This is the goal of the current research efforts involving the multi-group method and the Green's function approach.

To create a nationwide system to capture data on completed suicide in Malaysia i.e. the morbidity, geographic and temporal trends and the population at high risk of suicide. Data from this registry can later be used to stimulate and facilitate further research on suicide. This paper describes the rationale and processes involved in developing a national suicide registry in 2007. The diagnosis of suicide is based on the ICD-10 codes for fatal intentional self-harm (X60-X84). A case report form with an accompanying instruction manual had been prepared to ensure systematic and uniform data collection. State Forensic Pathologist's offices are responsible for data collection in their respective states, and in turn will submit the data to a central data management unit. Data collection began in July 2007 and currently in data cleaning process. Training for source data producers is ongoing. In 2008, the NSRM plans to involve university hospitals into its network as currently only Ministry of Health hospitals are involved. The NSRM will be launching its online application for case registration this year while an overview of results will be available via its public domain at www.nsrm.gov.my beginning 20 April 2008. To efficiently capture the data on suicide, a concerted effort between various agencies is needed. A lot of conceptual work and data base development remains to be done in order to position preventive efforts on a more solid foundation.

Current efforts to characterize the neuronal mechanisms that underlie automatic breathing generally adopt a 'minimalist' approach. In this review, we survey three of the many neurochemicals that are known to be present in raphe neurons and may be involved in respiration. Specifically, we ask the question, 'Is the minimalist approach consistent with the large number of neuronal types and neurochemicals found in respiratory centres'?

During the past decade, computational simulation of fluid flow around complex configurations has progressed significantly and many notable successes have been reported, however, unsteady time-dependent solutions are not easily obtainable. The present effort involves unsteady time dependent simulation of temporally deforming geometries. Grid generation for a complex configuration can be a time consuming process and temporally varying geometries necessitate the regeneration of such grids for every time step. Traditional grid generation techniques have been tried and demonstrated to be inadequate to such simulations. Non-Uniform Rational B-splines (NURBS) based techniques provide a compact and accurate representation of the geometry. This definition can be coupled with a distribution mesh for a user defined spacing. The present method greatly reduces cpu requirements for time dependent remeshing, facilitating the simulation of more complex unsteady problems. A thrust vectoring nozzle has been chosen to demonstrate the capability as it is of current interest in the aerospace industry for better maneuverability of fighter aircraft in close combat and in post stall regimes. This current effort is the first step towards multidisciplinary design optimization which involves coupling the aerodynamic heat transfer and structural analysis techniques. Applications include simulation of temporally deforming bodies and aeroelastic problems.
Biomaterial delivery of morphogens to mimic the natural healing cascade in bone
Mehta, Manav; Schmidt-Bleek, Katharina; Duda, Georg N; Mooney, David J
2012-01-01
Complications in treatment of large bone defects using bone grafting still remain. Our understanding of the endogenous bone regeneration cascade has inspired the exploration of a wide variety of growth factors (GFs) in an effort to mimic the natural signaling that controls bone healing. Biomaterial-based delivery of single exogenous GFs has shown therapeutic efficacy, and this likely relates to its ability to recruit and promote replication of cells involved in tissue development and the healing process. However, as the natural bone healing cascade involves the action of multiple factors, each acting in a specific spatiotemporal pattern, strategies aiming to mimic the critical aspects of this process will likely benefit from the usage of multiple therapeutic agents. This article reviews the current status of approaches to deliver single GFs, as well as ongoing efforts to develop sophisticated delivery platforms to deliver multiple lineage-directing morphogens (multiple GFs) during bone healing.

Prevention and harm reduction for chemical dependency: a process perspective.
DiClemente, C C
1999-06-01
Clinical psychology is often on the periphery of treatment and prevention efforts to stop substance abuse and dependence. This article describes the current status of prevention research and practice, outlines a process perspective on the initiation and cessation of drug use and abuse, and offers some new ideas about how psychology can and should become involved in the prevention of chemical dependency. Psychologists are faced with the precursors and consequences of chemical dependency on a daily basis. With improved training and increased awareness, and aided by a process perspective, psychology and psychologists can play an important role in preventing the onset of chemical dependency, creating early interventions to stop the process of initiation, and becoming more involved in treatment and harm-reduction efforts. Psychologists have the basic training and the biopsychosocial orientation that could make them effective agents for primary, secondary, and tertiary prevention of chemical dependency.
The Influence of Dating Relationships on Friendship Networks, Identity Development, and Delinquency
Seffrin, Patrick M.; Giordano, Peggy C.; Manning, Wendy D.; Longmore, Monica A.
2011-01-01
Prior research has documented general associations between dating and delinquency, but little is known about the specific ways in which heterosexual experiences influence levels of delinquency involvement and substance use. In the current study, we hypothesize that an adolescent’s level of effort and involvement in heterosexual relationships play a significant role in forming the types of friendship networks and views of self that influence the likelihood of delinquency involvement and substance use. Analyses based on a longitudinal sample of adolescent youth (n=1,090) show that high levels of dating effort and involvement with multiple partners significantly increases unstructured and delinquent peer contacts, and influences self-views as troublemaker. These broader peer contexts and related self-views, in turn, mediate the path between dating relationships, self-reported delinquency, and substance use. Findings also document moderation effects: among those youths who have developed a troublemaker identity and who associate with delinquent peers, dating heightens the risk for delinquent involvement. In contrast, among those individuals who have largely rejected the troublemaker identity and who do not associate with delinquent friends, dating relationships may confer a neutral or even protective benefit. The analyses further explore the role of gender and the delinquency of the romantic partner. PMID:21311739

There is substantial evidence of a need to make computation an integral part of the undergraduate physics curriculum. This need is consistent with data from surveys in both the academy and the workplace, and has been reinforced by two years of exploratory efforts by a group of physics faculty for whom computation is a special interest. We have examined past and current efforts at reform and a variety of strategic, organizational, and institutional issues involved in any attempt to broadly transform existing practice. We propose a set of guidelines for development based on this past work and discuss our vision of computationally integrated physics.
Effort-Based Decision Making: A Novel Approach for Assessing Motivation in Schizophrenia
Green, Michael F.; Horan, William P.; Barch, Deanna M.; Gold, James M.
2015-01-01
Because negative symptoms, including motivational deficits, are a critical unmet need in schizophrenia, there are many ongoing efforts to develop new pharmacological and psychosocial interventions for these impairments. A common challenge of these studies involves how to evaluate and select optimal endpoints. Currently, all studies of negative symptoms in schizophrenia depend on ratings from clinician-conducted interviews. Effort-based decision-making tasks may provide a more objective, and perhaps more sensitive, endpoint for trials of motivational negative symptoms. These tasks assess how much effort a person is willing to exert for a given level of reward. This area has been well-studied with animal models of effort and motivation, and effort-based decision-making tasks have been adapted for use in humans. Very recently, several studies have examined physical and cognitive types of effort-based decision-making tasks in cross-sectional studies of schizophrenia, providing evidence for effort-related impairment in this illness. This article covers the theoretical background on effort-based decision-making tasks to provide a context for the subsequent articles in this theme section. In addition, we review the existing literature of studies using these tasks in schizophrenia, consider some practical challenges in adapting them for use in clinical trials in schizophrenia, and discuss interpretive challenges that are central to these types of tasks.

Access to adequate surgical care is limited globally, particularly in low- and middle-income countries (LMICs). To address this issue, surgeons are becoming increasingly involved in international surgical teaching collaborations (ISTCs), which include educational partnerships between surgical teams in high-income countries and those in LMICs. The purpose of this study is to determine a framework for unifying, systematizing, and improving the quality of ISTCs so that they can better address the global surgical need. A convenience sample of 68 surgeons, anesthesiologists, physicians, residents, nurses, academics, and administrators from the U.S., Canada, and Norway was used for the study. Participants all had some involvement in ISTCs and came from multiple specialties and institutions. Qualitative methodology was used, and participants were interviewed using a pre-determined set of open-ended questions. Data was gathered over two months either in-person, over the phone, or on Skype. Data was evaluated using thematic content analysis. To organize and systematize ISTCs, participants reported a need for a centralized/systematized process with designated leaders, a universal data bank of current efforts/progress, communication amongst involved parties, full-time administrative staff, dedicated funds, a scholarly approach, increased use of technology, and more research on needs and outcomes. By taking steps towards unifying and systematizing ISTCs, the quality of ISTCs can be improved. This could lead to an advancement in efforts to increase access to surgical care worldwide.

The photospheres of cool stars are both rich in molecules and an environment where the assumption of LTE can not be upheld under all circumstances. Unfortunately, detailed 3D non-LTE calculations involving molecules are hardly feasible with current computers. For this reason, we present our implementation of the super level technique, in which molecular levels are combined into super levels, to reduce the number of unknowns in the rate equations and, thus, the computational effort and memory requirements involved, and show the results of our first tests against the 1D implementation of the same method.
Current anti-doping policy: a critical appraisal
Kayser, Bengt; Mauron, Alexandre; Miah, Andy
2007-01-01
Background Current anti-doping in competitive sports is advocated for reasons of fair-play and concern for the athlete's health. With the inception of the World Anti Doping Agency (WADA), anti-doping effort has been considerably intensified. Resources invested in anti-doping are rising steeply and increasingly involve public funding. Most of the effort concerns elite athletes with much less impact on amateur sports and the general public. Discussion We review this recent development of increasingly severe anti-doping control measures and find them based on questionable ethical grounds. The ethical foundation of the war on doping consists of largely unsubstantiated assumptions about fairness in sports and the concept of a "level playing field". Moreover, it relies on dubious claims about the protection of an athlete's health and the value of the essentialist view that sports achievements reflect natural capacities. In addition, costly antidoping efforts in elite competitive sports concern only a small fraction of the population. From a public health perspective this is problematic since the high prevalence of uncontrolled, medically unsupervised doping practiced in amateur sports and doping-like behaviour in the general population (substance use for performance enhancement outside sport) exposes greater numbers of people to potential harm. In addition, anti-doping has pushed doping and doping-like behaviour underground, thus fostering dangerous practices such as sharing needles for injection. Finally, we argue that the involvement of the medical profession in doping and anti-doping challenges the principles of non-maleficience and of privacy protection. As such, current anti-doping measures potentially introduce problems of greater impact than are solved, and place physicians working with athletes or in anti-doping settings in an ethically difficult position. In response, we argue on behalf of enhancement practices in sports within a framework of medical supervision. Summary Current anti-doping strategy is aimed at eradication of doping in elite sports by means of all-out repression, buttressed by a war-like ideology similar to the public discourse sustaining international efforts against illicit drugs. Rather than striving for eradication of doping in sports, which appears to be an unattainable goal, a more pragmatic approach aimed at controlled use and harm reduction may be a viable alternative to cope with doping and doping-like behaviour.

OBJECTIVE Neurosurgical services are increasingly recognized as essential components of surgical care worldwide. The degree of interest among neurosurgeons regarding international work, and the barriers to involvement in global neurosurgical outreach, are largely unexplored. The authors distributed a survey to members of the American Association of Neurological Surgeons/Congress of Neurological Surgeons (AANS/CNS) Joint Section on Pediatric Neurosurgery to assess the state of global outreach among its members and to identify barriers to involvement. METHODS An internet-based questionnaire was developed by the International Education Subcommittee of the AANS/CNS Joint Section on Pediatric Neurosurgery and distributed to pediatric neurosurgeons via the AANS/CNS Joint Section email contact list. Participants were surveyed on their involvement in global neurosurgical outreach, geographic location, nature of the participation, and barriers to further involvement. RESULTS A 35.3% response rate was obtained, with 116 respondents completing the survey. Sixty-one percent have performed or taught neurosurgery in a developing country, and 49% travel at least annually. Africa was the most common region (54%), followed by South America (30%), through 29 separate organizing entities. Hydrocephalus was the most commonly treated condition (88%), followed by spinal dysraphism (74%), and tumor (68%). Most respondents obtained follow-up through communications from local surgeons (77%). Seventy-one percent believed the international experience improved their practice, and 74% were very or extremely interested in working elsewhere. Interference with current practice (61%), cost (44%), and difficulty identifying international partners (43%) were the most commonly cited barriers to participation. CONCLUSIONS Any coordinated effort to expand global neurosurgical capacity begins with appreciation for the current state of outreach efforts. Increasing participation in global outreach will require addressing both real and perceived barriers to involvement. Creation and curation of a centralized online database of ongoing projects to facilitate coordination and involvement may be beneficial.

The launch environment is a challenging regime to work due to changing system dynamics, changing environmental loading, joint compression loads that cannot be easily applied on the ground, and control effects. Operational testing is one of the few feasible approaches to capture system level dynamics since ground testing cannot reproduce all of these conditions easily. However, the most successful applications of Operational Modal Testing involve systems with good stationarity and long data acquisition times. This paper covers an ongoing effort to understand the launch environment and the utility of current operational modal tools. This work is expected to produce a collection of operational tools that can be applied to non-stationary launch environment, experience dealing with launch data, and an expanding database of flight parameters such as damping. This paper reports on recent efforts to build a software framework for the data processing utilizing existing and specialty tools; understand the limits of current tools; assess a wider variety of current tools; and expand the experience with additional datasets as well as to begin to address issues raised in earlier launch analysis studies.
High current density sheet-like electron beam generator
NASA Astrophysics Data System (ADS)
Chow-Miller, Cora; Korevaar, Eric; Schuster, John
Sheet electron beams are very desirable for coupling to the evanescent waves in small millimeter wave slow-wave circuits to achieve higher powers. In particular, they are critical for operation of the free-electron-laser-like Orotron. The program was a systematic effort to establish a solid technology base for such a sheet-like electron emitter system that will facilitate the detailed studies of beam propagation stability. Specifically, the effort involved the design and test of a novel electron gun using Lanthanum hexaboride (LaB6) as the thermionic cathode material. Three sets of experiments were performed to measure beam propagation as a function of collector current, beam voltage, and heating power. The design demonstrated its reliability by delivering 386.5 hours of operation throughout the weeks of experimentation. In addition, the cathode survived two venting and pump down cycles without being poisoned or losing its emission characteristics. A current density of 10.7 A/sq cm. was measured while operating at 50 W of ohmic heating power. Preliminary results indicate that the nearby presence of a metal plate can stabilize the beam.

Over the past 3 years, NASA Ames has been involved in a cooperative effort with SGI to develop the largest single system image systems available. Currently a 1024 Origin3OOO is under development, with first boot expected later in the summer of 2001. This paper discusses some early results with a 512p Origin3OOO system and some arcane IRIX system calls that can dramatically improve scaling performance.
Future Orbital Power Systems Technology Requirements
NASA Technical Reports Server (NTRS)
1978-01-01
NASA is actively involved in program planning for missions requiring several orders of magnitude, more energy than in the past. Therefore, a two-day symposium was held to review the technology requirements for future orbital power systems. The purpose of the meeting was to give leaders from government and industry a broad view of current government supported technology efforts and future program plans in space power. It provided a forum for discussion, through workshops, to comment on current and planned programs and to identify opportunities for technology investment. Several papers are presented to review the technology status and the planned programs.
Multi-scale modeling in cell biology
Meier-Schellersheim, Martin; Fraser, Iain D. C.; Klauschen, Frederick
2009-01-01
Biomedical research frequently involves performing experiments and developing hypotheses that link different scales of biological systems such as, for instance, the scales of intracellular molecular interactions to the scale of cellular behavior and beyond to the behavior of cell populations. Computational modeling efforts that aim at exploring such multi-scale systems quantitatively with the help of simulations have to incorporate several different simulation techniques due to the different time and space scales involved. Here, we provide a non-technical overview of how different scales of experimental research can be combined with the appropriate computational modeling techniques. We also show that current modeling software permits building and simulating multi-scale models without having to become involved with the underlying technical details of computational modeling.

The prospect of gene therapy for prostate cancer: update on theory and status.
Koeneman, K S; Hsieh, J T
2001-09-01
Molecularly based novel therapeutic agents are needed to address the problem of locally recurrent, or metastatic, advanced hormone-refractory prostate cancer. Recent basic science advances in mechanisms of gene expression, vector delivery, and targeting have rendered clinically relevant gene therapy to the prostatic fossa and distant sites feasible in the near future. Current research and clinical investigative efforts involving methods for more effective vector delivery and targeting, with enhanced gene expression to selected (specific) sites, are reviewed. These areas of research involve tissue-specific promoters, transgene exploration, vector design and delivery, and selective vector targeting. The 'vectorology' involved mainly addresses selective tissue homing with ligands, mechanisms of innate immune system evasion for durable transgene expression, and the possibility of repeat administration.
Biomaterial delivery of morphogens to mimic the natural healing cascade in bone.
Mehta, Manav; Schmidt-Bleek, Katharina; Duda, Georg N; Mooney, David J
2012-09-01
Complications in treatment of large bone defects using bone grafting still remain. Our understanding of the endogenous bone regeneration cascade has inspired the exploration of a wide variety of growth factors (GFs) in an effort to mimic the natural signaling that controls bone healing. Biomaterial-based delivery of single exogenous GFs has shown therapeutic efficacy, and this likely relates to its ability to recruit and promote replication of cells involved in tissue development and the healing process. However, as the natural bone healing cascade involves the action of multiple factors, each acting in a specific spatiotemporal pattern, strategies aiming to mimic the critical aspects of this process will likely benefit from the usage of multiple therapeutic agents. This article reviews the current status of approaches to deliver single GFs, as well as ongoing efforts to develop sophisticated delivery platforms to deliver multiple lineage-directing morphogens (multiple GFs) during bone healing.

Brazilian pharmaceutical diplomacy: social democratic principles versus soft power interests.
Flynn, Matthew
2013-01-01
Current debates concerning the rise of health diplomacy are polarized between competing international relations theories of realism, based on power politics, and constructivist approaches, which emphasize the norms, values, and identities shaping foreign policies. A case study of Brazil's health diplomacy over the past 10 years, focusing on issues related to pharmaceuticals, seeks to provide data to assess these theories. The country's intellectual property disputes, multilateral lobbying efforts, and foreign assistance programs are contrasted with those of the United States, Mexico, and other countries. Instead of viewing Brazilian efforts as a form of soft power, the evidence suggests that the origins of Brazil's involvement and continued efforts in this arena stem more from values based on human rights and social democratic principles. A close examination of domestic political considerations leads to a more nuanced understanding of the drivers behind a country's health diplomacy.
European Union pharmacovigilance capabilities: potential for the new legislation
Tanti, Amy; Kouvelas, Dimitrios; Lungu, Calin; Pirozynski, Michal; Serracino-Inglott, Anthony; Aislaitner, George
2015-01-01
European Directives and Regulations introduced between late 2010 and 2012 have substantially overhauled pharmacovigilance processes across the European Union (EU). In this review, the implementation of the pharmacovigilance legislative framework by EU regulators is examined with the aim of mapping Directive 2010/84/EU and Regulation EC No. 1235/2010 against their aspired objectives of strengthening and rationalizing pharmacovigilance in the EU. A comprehensive review of the current state of affairs of the progress made by EU regulators is presented in this paper. Our review shows that intense efforts by regulators and industry to fulfil legislative obligations have resulted in major positive shifts in pharmacovigilance. Harmonized decision making, transparency in decision processes with patient involvement, information accessibility to the public, patient adverse drug reaction reporting, efforts in communication and enhanced cooperation between member states to maximize resource utilization and minimize duplication of efforts are observed.

Investigative study of holographic recording materials development
NASA Technical Reports Server (NTRS)
1972-01-01
The potential of certain cis-trans isomers and doped LiNbO3 for the holographic read/write/erase memory application was investigated. The cis-trans work involved the photochemical investigation of a number of potential materials as well as specific molecular engineering efforts on alpha-methyl stilbene and its derivatives. These efforts resulted in an increase in the change in index of refraction, and thereby, in potential recording utility, of an order of magnitude. The work on LiNbO3 was directed toward a preliminary investigation of the dynamics of the writing process. Several samples and a variety of writing conditions were investigated. An unexpected and as yet unexplained improvement in material behavior with continued recycling was observed. In addition, some effort was devoted to an analysis of the physical conditions under which several current theories of the optical damage process are valid.

A highly pathogenic avian influenza (HPAI) outbreak in the United States will initiate a federal emergency response effort that will consist of disease control and eradication efforts, including quarantine and movement control measures. These movement control measures will not only apply to live animals but also to animal products. However, with current egg industry "just-in-time" production practices, limited storage is available to hold eggs. As a result, stop movement orders can have significant unintended negative consequences, including severe disruptions to the food supply chain. Because stakeholders' perceptions of risk vary, waiting to initiate communication efforts until an HPAI event occurs can hinder disease control efforts, including the willingness of producers to comply with the response, and also can affect consumers' demand for the product. A public-private-academic partnership was formed to assess actual risks involved in the movement of egg industry products during an HPAI event through product specific, proactive risk assessments. The risk analysis process engaged a broad representation of stakeholders and promoted effective risk management and communication strategies before an HPAI outbreak event. This multidisciplinary team used the risk assessments in the development of the United States Department of Agriculture, Highly Pathogenic Avian Influenza Secure Egg Supply Plan, a comprehensive response plan that strives to maintain continuity of business. The collaborative approach that was used demonstrates how a proactive risk communication strategy that involves many different stakeholders can be valuable in the development of a foreign animal disease response plan and build working relationships, trust, and understanding.

Policy makers draw on behavioral research to design interventions that promote the voluntary adoption of environmental behavior in societies. Many environmental behaviors will only be effective if they are maintained over the long-term. In the context of climate change and concerns about future water security, behaviors that involve reducing energy consumption and improving water quality must be continued indefinitely to mitigate global warming and preserve scarce resources. Previous reviews of environmental behavior have focused exclusively on factors related to adoption. This review investigates the factors that influence both adoption and maintenance, and presents a classification of environmental behaviors in terms of the activities, costs, and effort required for both adoption and maintenance. Three categories of behavior are suggested. One-off behaviors involve performing an activity once, such as purchasing an energy efficient washing machine, or signing a petition. Continuous behaviors involve the performance of the same set of behaviors for adoption and for maintenance, such as curbside recycling. Dynamic behaviors involve the performance of different behaviors for adoption and maintenance, such as revegetation. Behaviors can also be classified into four categories related to cost and effort: those that involve little cost and effort for adoption and maintenance, those that involve moderate cost and effort for adoption and maintenance, those that involve a high cost or effort for adoption and less for maintenance, and those that involve less cost or effort for adoption and a higher amount for maintenance. In order to design interventions that last, policy makers should consider the factors that influence the maintenance as well as the adoption of environmental behaviors. PMID:29163265

At any time in history, a few scientific measurements disagreed with the best theoretical predictions of the time. Currently, one such discrepancy involves the measurement of the strength of the magnetic field of a subatomic particle called a muon. In this video, Fermilab’s Dr. Don Lincoln explains this mystery and sketches ongoing efforts to determine if this disagreement signifies a discovery. If it does, this measurement will mean that we will have to rewrite the textbooks.

Autonomous Vehicle technology is quickly expanding its market and has found in Silicon Valley, California, a strong foothold for preliminary testing on public roads. In an effort to promote safety and transparency to consumers, the California Department of Motor Vehicles has mandated that reports of accidents involving autonomous vehicles be drafted and made available to the public. The present work shows an in-depth analysis of the accident reports filed by different manufacturers that are testing autonomous vehicles in California (testing data from September 2014 to March 2017). The data provides important information on autonomous vehicles accidents’ dynamics, related to the most frequent types of collisions and impacts, accident frequencies, and other contributing factors. The study also explores important implications related to future testing and validation of semi-autonomous vehicles, tracing the investigation back to current literature as well as to the current regulatory panorama.

Many experimental and theoretical advances have recently allowed the study of direct and indirect effects of low-energy electrons (LEEs) on DNA damage. In an effort to explain how LEEs damage the human genome, researchers have focused efforts on LEE interactions with bacterial plasmids, DNA bases, sugar analogs, phosphate groups, and longer DNA moieties. Here, we summarize the current understanding of the fundamental mechanisms involved in LEE-induced damage of DNA and complex biomolecule films. Results obtained by several laboratories on films prepared and analyzed by different methods and irradiated with different electron-beam current densities and fluencies are presented. Despite varied conditions (e.g., film thicknesses and morphologies, intrinsic water content, substrate interactions, and extrinsic atmospheric compositions), comparisons show a striking resemblance in the types of damage produced and their yield functions. The potential of controlling this damage using molecular and nanoparticle targets with high LEE yields in targeted radiation-based cancer therapies is also discussed.
A noninterference blade vibration measurement system for gas turbine engines
NASA Astrophysics Data System (ADS)
Watkins, William B.; Chi, Ray M.
1987-06-01
A noninterfering blade vibration system has been demonstrated in tests of a gas turbine first stage fan. Conceptual design of the system, including its theory, design of case mounted probes, and data acquisition and signal processing hardware was done in a previous effort. The current effort involved instrumentation of an engine fan stage with strain gages; data acquisition using shaft-mounted reference and case-mounted optical probes; recording of data on a wideband tape recorder; and posttest processing using off-line analysis in a facility computer and a minicomputer-based readout system designed for near- real-time readout. Results are presented in terms of true blade vibration frequencies, time and frequency dependent vibration amplitudes and comparison of the optical noninterference results with strain gage readings.

The business of interventional pulmonology.
Erb, Christopher T; Ernst, Armin; Michaud, Gaëtane C
2013-09-01
Interventional pulmonologists are regularly asked to perform more complicated and advanced procedures, but reimbursement for the time, effort and skill involved in these procedures has not kept up with other procedural specialties. Further changes in funding and reimbursement are likely under the Affordable Care Act. Understanding and effectively using the current system of funding for interventional pulmonology practices are imperative as we adapt to changing medical needs, legislative mandates, and reimbursement policy. This article reviews the current landscape of insurance and reimbursement in health care and anticipates some changes that might be expected from implementation of the Affordable Care Act.

The workshop brought together researchers involved in the NASA formal methods research effort for detailed technical interchange and provided a mechanism for interaction with representatives from the FAA and the aerospace industry. The workshop also included speakers from industry to debrief the formal methods researchers on the current state of practice in flight critical system design, verification, and certification. The goals were: define and characterize the verification problem for ultra-reliable life critical flight control systems and the current state of practice in industry today; determine the proper role of formal methods in addressing these problems, and assess the state of the art and recent progress toward applying formal methods to this area.
The politics of participation in watershed modeling.
Korfmacher, K S
2001-02-01
While researchers and decision-makers increasingly recognize the importance of public participation in environmental decision-making, there is less agreement about how to involve the public. One of the most controversial issues is how to involve citizens in producing scientific information. Although this question is relevant to many areas of environmental policy, it has come to the fore in watershed management. Increasingly, the public is becoming involved in the sophisticated computer modeling efforts that have been developed to inform watershed management decisions. These models typically have been treated as technical inputs to the policy process. However, model-building itself involves numerous assumptions, judgments, and decisions that are relevant to the public. This paper examines the politics of public involvement in watershed modeling efforts and proposes five guidelines for good practice for such efforts. Using these guidelines, I analyze four cases in which different approaches to public involvement in the modeling process have been attempted and make recommendations for future efforts to involve communities in watershed modeling.

Effort-Based Decision Making: A Novel Approach for Assessing Motivation in Schizophrenia.
Green, Michael F; Horan, William P; Barch, Deanna M; Gold, James M
2015-09-01
Because negative symptoms, including motivational deficits, are a critical unmet need in schizophrenia, there are many ongoing efforts to develop new pharmacological and psychosocial interventions for these impairments. A common challenge of these studies involves how to evaluate and select optimal endpoints. Currently, all studies of negative symptoms in schizophrenia depend on ratings from clinician-conducted interviews. Effort-based decision-making tasks may provide a more objective, and perhaps more sensitive, endpoint for trials of motivational negative symptoms. These tasks assess how much effort a person is willing to exert for a given level of reward. This area has been well-studied with animal models of effort and motivation, and effort-based decision-making tasks have been adapted for use in humans. Very recently, several studies have examined physical and cognitive types of effort-based decision-making tasks in cross-sectional studies of schizophrenia, providing evidence for effort-related impairment in this illness. This article covers the theoretical background on effort-based decision-making tasks to provide a context for the subsequent articles in this theme section. In addition, we review the existing literature of studies using these tasks in schizophrenia, consider some practical challenges in adapting them for use in clinical trials in schizophrenia, and discuss interpretive challenges that are central to these types of tasks. © The Author 2015.

Expressed Emotion, Shame, and Non-Suicidal Self-Injury
Hack, Jessica; Martin, Graham
2018-01-01
A cross-sectional study examining relationships between perceived family Expressed Emotion and shame, emotional involvement, depression, anxiety, stress and non-suicidal self-injury, in 264 community and online adults (21.6% male). We compared self-injurers with non-self-injurers, and current with past self-injurers. Self-injurers experienced more family Expressed Emotion (EE) than non-injurers (t(254) = −3.24, p = 0.001), linear contrasts explaining 6% of between-groups variability (F(2, 254) = 7.36, p = 0.001, η2 = 0.06). Differences in EE between current and past self-injurers were not significant. Overall shame accounted for 33% of between-groups variance (F(2, 252) = 61.99, p < 0.001, η2 = 0.33), with linear contrasts indicating self-injurers experienced higher levels compared to non-injurers (t(252) = −8.23, p < 0.001). Current self-injurers reported higher overall shame than past self-injurers (t(252) = 6.78, p < 0.001). In further logistic regression, emotional involvement and overall shame were the only significant predictors of self-injury status. With every one-unit increase in emotional involvement, odds of currently engaging in self-injury decreased by a factor of 0.860. Conversely, a one-unit increase in overall shame was associated with an increase in the odds of being a current self-injurer by a factor of 1.05. The findings have important treatment implications for engaging key family members in intervention and prevention efforts. PMID:29710866

This paper describes an assessment of community readiness to implement a community-wide teen pregnancy prevention initiative, Youth First, and presents strategies used to enhance this readiness as informed by the assessment. Twenty-five community stakeholder interviews were conducted to assess four domains of readiness: (1) attitudes, perception, and knowledge of teen pregnancy; (2) perceived level of readiness; (3) resources, existing and current efforts; and (4) leadership. Interview transcripts were coded and analyzed to identify key themes. Stakeholders acknowledged teen pregnancy as an issue but lacked contextual information. They also perceived the community as ready to address the issue and recognized some organizations already championing efforts. However, many key players were not involved, and ongoing data collection to assess teen pregnancy and prevention efforts was limited. Though many stakeholders were ready to engage in teen pregnancy prevention efforts, they required additional information and training to appropriately address the issue. In response to the assessment findings, several strategies were applied to address readiness and build Youth First partners' capacity to implement the community-wide initiative. Thus, to successfully implement community-wide prevention efforts, it is valuable to assess the level of community readiness to address health issues.

This study was designed to explore the experiences of urban parents in their role as Collaborative Board members as part of the CHAMP (Collaborative HIV prevention and Adolescent Mental health Project) Family Program Study. The CHAMP Collaborative Board is comprised of urban parents, representatives from schools and community-based agencies and university-based researchers and is charged with overseeing the design, delivery and testing of a family-based HIV prevention program for pre and early adolescent youth. The current qualitative study, guided by the Theory of Unified Behavior Change, is meant to elucidate: (1) pathways to involvement by urban parents; (2) benefits and costs of participating in this collaborative HIV prevention research effort; and (3) the role of social relationships in influencing initial and ongoing participation by parent participants. Twenty-nine parent Collaborative Board members were interviewed for this study. In-depth interviews were audio recorded and ranged from 30 to 90 minutes in length. Transcripts were coded and analyzed using NUD*IST, computerized software used for examining narratives. Findings include community parent members identifying social support and learning opportunities as major reasons for involvement with the Collaborative Board. Prior involvement with other community-based projects and knowledge of at least one other person on the Board also influenced members to join the Board and remain involved over time. Further, recommendations for future collaborative partnerships are made. Findings have direct implication for participatory HIV prevention research activities.

Trammell, Michael P; Jolly, Brian C; Miller, James Henry
ORNL is currently recapturing graphite based fuel forms for Nuclear Thermal Propulsion (NTP). This effort involves research and development on materials selection, extrusion, and coating processes to produce fuel elements representative of historical ROVER and NERVA fuel. Initially, lab scale specimens were fabricated using surrogate oxides to develop processing parameters that could be applied to full length NTP fuel elements. Progress toward understanding the effect of these processing parameters on surrogate fuel microstructure is presented.

At any time in history, a few scientific measurements disagreed with the best theoretical predictions of the time. Currently, one such discrepancy involves the measurement of the strength of the magnetic field of a subatomic particle called a muon. In this video, Fermilabâs Dr. Don Lincoln explains this mystery and sketches ongoing efforts to determine if this disagreement signifies a discovery. If it does, this measurement will mean that we will have to rewrite the textbooks.
An introduction to global carbon cycle management
Sundquist, Eric T.; Ackerman, Katherine V.; Parker, Lauren; Huntzinger, Deborah N.
2009-01-01
Past and current human activities have fundamentally altered the global carbon cycle. Potential future efforts to control atmospheric CO2 will also involve significant changes in the global carbon cycle. Carbon cycle scientists and engineers now face not only the difficulties of recording and understanding past and present changes but also the challenge of providing information and tools for new management strategies that are responsive to societal needs. The challenge is nothing less than managing the global carbon cycle.

An enigmatic prediction of Einstein's general theory of relativity is gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein's theory, the existence of gravitational waves was firmly established. Currently there is a worldwide effort to detect gravitational waves with inteferometric gravitational wave observatories or detectors and several such detectors have been built or being built. The initial detectors have reached their design sensitivities and now the effort is on to construct advanced detectors which are expected to detect gravitational waves from astrophysical sources. The era of gravitational wave astronomy has arrived. This article describes the worldwide effort which includes the effort on the Indian front - the IndIGO project -, the principle underlying interferometric detectors both on ground and in space, the principal noise sources that plague such detectors, the astrophysical sources of gravitational waves that one expects to detect by these detectors and some glimpse of the data analysis methods involved in extracting the very weak gravitational wave signals from detector noise.

The NASA Education and Public Outreach (E/PO) Forums support scientists who are involved in E/PO and who wish to be involved. Over the past five years, we have conducted over 30 interviews with planetary scientists, in collaboration with the AAS Division of Planetary Sciences, to better understand their needs, barriers, attitudes, and understanding of education and outreach work. Scientists were asked to describe how they were engaged in E/PO activities, what support they currently had, what resources they were aware of, and what resources they needed to support their engagement of E/PO.Respondents reported that E/PO was important to them, even if they were not actively involved in it themselves. They reported that most of their efforts, other than university teaching, were done on a volunteer basis. Scientists reported barriers to their involvement in E/PO, the most prominent were a lack of time and funding. Some expressed confusion how to get started and a lack of knowledge about resources that could assist them. They reported a need for resources and professional development to support their E/PO work, including information about how to get involved in E/PO and how to work with students in a classroom, training to become a better communicator, strategies to effectively do E/PO, and resources to bring NASA science into their college classrooms.As a result of this work, the NASA SMD Forums have created resources and increased efforts to connect scientists to resources to support their efforts in E/PO including NASA Wavelength (nasawavelength.org) a source of peer reviewed resources for formal and informal educators, resources and tips guides for getting started and partnering in E/PO, and resources to higher education. These resources are available to anyone and can be found on the NASA SMD community site, http://smdepo.org.
Transputer parallel processing at NASA Lewis Research Center

Ellis, Graham K.
1989-01-01
The transputer parallel processing lab at NASA Lewis Research Center (LeRC) consists of 69 processors (transputers) that can be connected into various networks for use in general purpose concurrent processing applications. The main goal of the lab is to develop concurrent scientific and engineering application programs that will take advantage of the computational speed increases available on a parallel processor over the traditional sequential processor. Current research involves the development of basic programming tools. These tools will help standardize program interfaces to specific hardware by providing a set of common libraries for applications programmers. The thrust of the current effort is in developing a set of tools for graphics rendering/animation. The applications programmer currently has two options for on-screen plotting. One option can be used for static graphics displays and the other can be used for animated motion. The option for static display involves the use of 2-D graphics primitives that can be called from within an application program. These routines perform the standard 2-D geometric graphics operations in real-coordinate space as well as allowing multiple windows on a single screen.

Despite the documented relationship between parental substance abuse and youth delinquency, the effects of parental interventions on delinquency outcomes are unknown. Such interventions are particularly vital for families in the child welfare system who are at heightened risk for both parental substance involvement and youth delinquency. The current study tested the impact of intensive case management in the form of a recovery coach for substance-involved mothers on youth delinquency outcomes among a randomized sample of 453 families involved in a Title IV-E experimental waiver demonstration in Cook County, Illinois. In comparison to control group participants, families enrolled in the Alcohol and Other Drug Abuse (AODA) waiver demonstration experienced a lower rate of juvenile arrest, net of factors such as demographic characteristics, primary drug of choice, and time spent in substitute care. Findings support efforts to curb delinquency among child-welfare involved youth by providing recovery coaches to their substance abusing or dependent parents. © 2013.
Interlibrary cooperation: from ILL to IAIMS and beyond.
Riordan, M L; Perry, G J
1999-07-01
A recent solicitation over the MEDLIB-L e-mail discussion list revealed over thirty diverse examples of hospital library-based interlibrary cooperative initiatives currently underway. Many are familiar and have been featured in the professional literature. Most go unreported and unrecognized however, comprising invisible resource-sharing infrastructures that hospital librarians painstakingly piece together in order to provide their clients with expanded service options. This paper, drawing from the MEDLIB-L survey as well as descriptions in the published literature, provides a broad overview of such recent interlibrary cooperative efforts. Examples include interlibrary loan networks, collective purchasing initiatives, holder-of-record or union catalog access agreements, arrangements to provide e-mail and Internet access, and consortia to share electronic resources. Examples were chosen based on the initiatives' diversity of participants, and represent a wide range of locations across the United States. Such initiatives focus on local, statewide, or regional collaboration, and several involve partnerships between academic medical center libraries and regional hospital libraries. An early example of a hospital-based interlibrary cooperative IAIMS effort is described, pointing to future possibilities involving the Internet and regional hospital system intranets.

Anti-EGFR Agents: Current Status, Forecasts and Future Directions.
Kwapiszewski, Radoslaw; Pawlak, Sebastian D; Adamkiewicz, Karolina
2016-12-01
The epidermal growth factor receptor (EGFR) is one of the most important and attractive targets for specific anticancer therapies. It is a robust regulator of pathways involved in cancer pathogenesis and progression. Thus far, clinical trials have demonstrated the benefits of monoclonal antibodies and synthetic tyrosine kinase inhibitors in targeting this receptor; however, novel strategies are still being developed. This article reviews the current state of efforts in targeting the EGFR in cancer therapy. Following a brief characterization of EGFR, we will present a complete list of anti-EGFR agents that are already approved, and available in clinical practice. Aside from the indications, we will present the sales forecasts and expiry dates of product patents for the selected agents. Finally, we discuss the novel anti-EGFR strategies that are currently in preclinical development.

The most exciting prospects for complexity science today are in the social sciences. Migration is a good example. According to the UN 720 million people worldwide are currently internal migrants and 120 million are international migrants. How many will there be in 2030, from where and to where do they migrate, why, at what costs and what are the consequences? We require a cross-disciplinary effort involving tools from complexity science, political science, social science, environmental science, psychology, epidemiology, biochemistry, and mathematics to tackle these questions...
Longitudinal Associations in Youth Involvement as Victimized, Bullying, or Witnessing Cyberbullying.
Holfeld, Brett; Mishna, Faye
2018-04-01
Although cyberbullying has been linked to cyber victimization, it is unknown whether witnessing cyberbullying impacts and is impacted by experiences of cyberbullying and victimization. In the current study, we examine the frequency of youth involved as victimized, bullying, and witnessing cyberbullying and how these experiences are associated across three academic years. Participants comprised 670 Canadian students who began the longitudinal study in grades 4, 7, or 10 at Time 1 (T1). Cyber witnessing represented the largest role of youth involvement in cyberbullying. Cyber witnessing was positively associated with both cyberbullying and victimization. Cyber victimization at T1 was positively associated with cyber witnessing at T2, which was positively related to both cyberbullying and victimization at T3. Findings highlight the significance of addressing the role of cyber witnesses in cyberbullying prevention and intervention efforts.

2002-01-01
Over the past decade, Low Earth Orbiting (LEO) spacecraft have gradually required ever-increasing power levels. As a rule, this has been accomplished through the use of high voltage systems. Recent failures and anomalies on such spacecraft have been traced to various design practices and materials choices related to the high voltage solar arrays. NASA Glenn has studied these anomalies including plasma chamber testing on arrays similar to those that experienced difficulties on orbit. Many others in the community have been involved in a comprehensive effort to understand the problems and to develop practices to avoid them. The NASA Space Environments and Effects program, recognizing the timeliness of this effort, has commissioned and funded a design guidelines document intended to capture the current state of understanding. We present here an overview of this document, which is now nearing completion.

Users of remote sensing data are increasingly turning to digital processing techniques for the extraction of land resource, environmental, and natural resource information. This paper presents the results of recent and ongoing research efforts sponsored, in part, by NASA/Marshall Space Flight Center on the current uses of and future needs for digital remote sensing data. An ongoing investigation involves a comprehensive survey of capabilities for digital Landsat data use in the Southeastern U.S. Another effort consists of an evaluation of future needs for digital remote sensing data by federal, state, and local governments and the private sector. These needs are projected into the 1980-1985 time frame. Furthermore, the accelerating use of digital remote sensing data is not limited to the U.S. or even to the developed countries of the world.
Microcirculation and the physiome projects.
Bassingthwaighte, James B
2008-11-01
The Physiome projects comprise a loosely knit worldwide effort to define the Physiome through databases and theoretical models, with the goal of better understanding the integrative functions of cells, organs, and organisms. The projects involve developing and archiving models, providing centralized databases, and linking experimental information and models from many laboratories into self-consistent frameworks. Increasingly accurate and complete models that embody quantitative biological hypotheses, adhere to high standards, and are publicly available and reproducible, together with refined and curated data, will enable biological scientists to advance integrative, analytical, and predictive approaches to the study of medicine and physiology. This review discusses the rationale and history of the Physiome projects, the role of theoretical models in the development of the Physiome, and the current status of efforts in this area addressing the microcirculation.

Work this summer in the Office of Safety, Environment, and Mission Assurance began with a review of current initiatives and environmental projects at the Langley Research Center (LaRC). This involved researching many of the documents on file which detail problems which have occurred as well as various approaches which have been used to address these problems. A large portion of the time was spent interviewing and working with each of the engineers, industrial hygienists and other professionals connected with the Office of Environmental Engineering. A few of the projects I worked on include: Researching environmental compliance, and pollution prevention efforts; touring many of the facilities at LaRC to observe the environmental efforts in the work place; researching equipment needs for the recycling/reclamation center; writing scripts for in-house training videos; working with the video production department to produce a training video; developing e-mail distribution list; developing environmental coordinator's database; and working with others to research logistics of recycling and waste minimization efforts.

Efforts to identify the genetic underpinnings of rare undiagnosed diseases increasingly involve the use of next-generation sequencing and comparative genomic hybridization methods. These efforts are limited by a lack of knowledge regarding gene function, and an inability to predict the impact of genetic variation on the encoded protein function. Diagnostic challenges posed by undiagnosed diseases have solutions in model organism research, which provides a wealth of detailed biological information. Model organism geneticists are by necessity experts in particular genes, gene families, specific organs, and biological functions. Here, we review the current state of research into undiagnosed diseases, highlighting large efforts in North America and internationally, including the Undiagnosed Diseases Network (UDN) (Supplemental Material, File S1) and UDN International (UDNI), the Centers for Mendelian Genomics (CMG), and the Canadian Rare Diseases Models and Mechanisms Network (RDMM). We discuss how merging human genetics with model organism research guides experimental studies to solve these medical mysteries, gain new insights into disease pathogenesis, and uncover new therapeutic strategies.

Nease, A. D.; Alexander, E. F.
1993-01-01
The Air Force has several missions which generate unique requirements that are being met through the development of construction robotic technology. One especially important mission will be the conduct of Department of Defense (DOD) space activities. Space operations and other missions place construction/repair equipment operators in dangerous environments and potentially harmful situations. Additionally, force reductions require that human resources be leveraged to the maximum extent possible, and more stringent construction repair requirements push for increased automation. To solve these problems, the U.S. Air Force is undertaking a research and development effort at Tyndall AFB, FL, to develop robotic construction/repair equipment. This development effort involves the following technologies: teleoperation, telerobotics, construction operations (excavation, grading, leveling, tool change), robotic vehicle communications, vehicle navigation, mission/vehicle task control architecture, and associated computing environment. The ultimate goal is the fielding of a robotic repair capability operating at the level of supervised autonomy. This paper will discuss current and planned efforts in space construction/repair, explosive ordnance disposal, hazardous waste cleanup, and fire fighting.
Private sector involvement in civil space remote sensing. Volume 1: Report
NASA Technical Reports Server (NTRS)
1979-01-01
A survey of private sector developers, users, and interpreters of Earth resources data was conducted in an effort to encourage private investment and participation in remote sensing systems. Results indicate positive interest in participation beyond the current hardware contracting level, however, there is a substantial gap between current market levels and system costs. Issues identified include the selection process for an operating entity, the public/private interface, data collection and access policies, price and profit regulation in a subsidized system, international participation, and the responsibility for research and development. It was agreed that the cost, complexity, and security implications of integrated systems need not be an absolute bar to their private operation.
Overview of NASA's Thermal Control System Development for Exploration Project
NASA Technical Reports Server (NTRS)
Stephan, Ryan A.
2011-01-01
The now-cancelled Constellation Program included the Orion, Altair, and Lunar Surface Systems project offices. The first two elements, Orion and Altair, were planned to be manned space vehicles while the third element was much more diverse and included several sub-elements. Among other things, these sub-elements were Rovers and a Lunar Habitat. The planned missions involving these systems and vehicles included several risks and design challenges. Due to the unique thermal operating environment, many of these risks and challenges were associated with the vehicles thermal control system. NASA s Exploration Technology Development Program (ETDP) consisted of various technology development projects. The project chartered with mitigating the aforementioned thermal risks and design challenges was the Thermal Control System Development for Exploration Project. These risks and design challenges were being addressed through a rigorous technology development process that was planned to culminate with an integrated thermal control system test. Although the technologies being developed were originally aimed towards mitigating specific Constellation risks, the technology development process is being continued within a new program. This continued effort is justified by the fact that many of the technologies are generically applicable to future spacecraft thermal control systems. The current paper summarizes the development efforts being performed by the technology development project. The development efforts involve heat acquisition and heat rejection hardware including radiators, heat exchangers, and evaporators. The project has also been developing advanced phase change material heat sinks and performing a material compatibility assessment for a promising thermal control system working fluid. The to-date progress and lessons-learned from these development efforts will be discussed throughout the paper.
The HUPO proteomics standards initiative--overcoming the fragmentation of proteomics data.
Hermjakob, Henning
2006-09-01
Proteomics is a key field of modern biomolecular research, with many small and large scale efforts producing a wealth of proteomics data. However, the vast majority of this data is never exploited to its full potential. Even in publicly funded projects, often the raw data generated in a specific context is analysed, conclusions are drawn and published, but little attention is paid to systematic documentation, archiving, and public access to the data supporting the scientific results. It is often difficult to validate the results stated in a particular publication, and even simple global questions like "In which cellular contexts has my protein of interest been observed?" can currently not be answered with realistic effort, due to a lack of standardised reporting and collection of proteomics data. The Proteomics Standards Initiative (PSI), a work group of the Human Proteome Organisation (HUPO), defines community standards for data representation in proteomics to facilitate systematic data capture, comparison, exchange and verification. In this article we provide an overview of PSI organisational structure, activities, and current results, as well as ways to get involved in the broad-based, open PSI process.
Reliability Issues in Stirling Radioisotope Power Systems
NASA Technical Reports Server (NTRS)
Schreiber, Jeffrey; Shah, Ashwin
2005-01-01
Stirling power conversion is a potential candidate for use in a Radioisotope Power System (RPS) for space science missions because it offers a multifold increase in the conversion efficiency of heat to electric power and reduced requirement of radioactive material. Reliability of an RPS that utilizes Stirling power conversion technology is important in order to ascertain long term successful performance. Owing to long life time requirement (14 years), it is difficult to perform long-term tests that encompass all the uncertainties involved in the design variables of components and subsystems comprising the RPS. The requirement for uninterrupted performance reliability and related issues are discussed, and some of the critical areas of concern are identified. An overview of the current on-going efforts to understand component life, design variables at the component and system levels, and related sources and nature of uncertainties are also discussed. Current status of the 110 watt Stirling Radioisotope Generator (SRG110) reliability efforts is described. Additionally, an approach showing the use of past experience on other successfully used power systems to develop a reliability plan for the SRG110 design is outlined.

This mixed method study examined current practices and barriers for screening and assessing substance use among youth/young adults in community mental health systems. Substance use rates remain high among youth/young adults in the general population and substance use disorders are prevalent among young people involved in public service systems such as mental health. In an effort to understand the dynamics for early intervention, 64 case managers and/or clinical directors from children's mental health systems in two states participated in an online survey or focus group in fall 2008. Quantitative survey questions and qualitative focus group questions explored attitudes and perspectives about screening and early intervention for substance use among youth/young adults involved in the mental health system and current agency practices. Mixed method results suggest a number of barriers to substance use screening and early intervention and point to innovations that could be more effectively supported.
Implications of non-specific strigolactone signaling in the rhizosphere.
Koltai, Hinanit
2014-08-01
Strigolactones produced by various plant species are involved in the development of different plant parts. They are also exuded by plant roots to the rhizosphere, where they are involved in the induction of seed germination of the parasitic plants Striga and Orobanche, hyphal branching of the symbiotic arbuscular mycorrhizal fungi (AMF), and the symbiotic interaction with Rhizobium. In the present discussion paper, the essentialness of strigolactones as communication signals in these plant interactions is discussed in view of the existence of other plant-derived substances that are able to promote these plant interactions. In addition, the importance of strigolactones for determination of interaction specificity is discussed based on current knowledge on strigolactone composition, perception and delivery. The different activities of strigolactones in plant development and in the rhizosphere suggest their possible use in agriculture. However, despite efforts made in this direction, there is no current, practical implementation. Possible reasons for the encountered difficulties and suggested solutions to promote strigolactone use in agriculture are discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Despite over two decades of efforts towards involving indigenous and traditional peoples in protected area management, there are few successful examples. Several international principles and guidelines on indigenous peoples' involvement in protected areas exist. However, because of the lack of evaluation of whether or not these principles and guidelines have been put into practice, there is hardly any information that indicates the actual involvement of indigenous peoples in protected areas. This paper attempts to compare efforts in partnership between indigenous peoples and protected area authority in three Asian countries: Nepal, Thailand, and China. It shows that the involvement of indigenous peoples is more successful where park planning is participatory and where political and socioeconomic reforms are underway. Indigenous peoples are in conflict with park authorities where park management is centralized and nonparticipatory. Unless concrete efforts are made to address livelihood issues of indigenous peoples living in and around protected areas, park management aimed to protect wildlife will rarely succeed. Participatory park management that involves indigenous peoples and that addresses livelihood issues of indigenous communities will ultimately succeed in its efforts toward wildlife conservation.

The Boeing Company is investigating the feasibility of building a second generation supersonic transport. If current studies support its viability, this airplane, known as the High Speed Civil Transport (HSCT), could be launched early in the next century. The HSCT will cruise at Mach 2.4, be over 300 feet long, have an initial range of between 5000 and 6000 NM, and carry approximately 300 passengers. We are presently involved in developing an advanced flight deck for the HSCT. As part of this effort we are undertaking a human engineering analysis that involves a top-down, mission driven approach that will allow a systematic determination of flight deck functional and information requirements. The present paper describes this work.
Teachers' Training and Involvement in School Health Programme in Oyo State, Southwest Nigeria.
Adebayo, A M; Makinde, G I; Omode, P K
2018-02-01
School Health Programme (SHP) currently lacks effective implementation in Nigeria. Lack of training/orientation of teachers in the programme may have contributed to this. Developing an appropriate training intervention may require prior situation analysis to know teachers' current level of training and involvement in the programme, as there is paucity of information on such study in Oyo State. Thus, this study was carried out to assess primary school teachers' training and involvement in the SHP in Oyo state, Nigeria. A descriptive cross-sectional study was conducted using a 2-stage cluster sampling method to select 2 out of the 33 Local Government Areas (LGAs) in Oyo State. A semi-structured self-administered questionnaire was used to obtain information on respondents' characteristics and previous training and involvement in the SHP. The major variable for assessing teachers' involvement in the SHP was "ever been involved in health inspection of pupils". Level of involvement was categorized into "never, "once", "occasionally", "frequently", and "very regularly". These options were further re-categorized into "never", "infrequently" (once and occasionally) and "frequently" (frequently and very regularly) for the purpose of inferential statistics. Data were analyzed using descriptive statistics and Chi-square test at p=0.05. A total of 811 respondents participated in the study. Twenty-eight percent of the respondents reported previous training in the SHP out of whom 44.7% received the training on-the-job. Forty-seven percent were regularly involved in health inspection of pupils. Teachers who taught health education (92.3%) were involved in health inspection of pupils compared with counterparts who did not (74.4%) (p<0.001). Similarly, 85.3% of teachers trained on-the-job were frequently involved in the SHP compared with 73.6% of those trained during undergraduate years (p=0.026). Training and involvement of public primary school teachers in the SHP in Oyo State were suboptimal. Efforts at building the capacity of teachers through on-the-job training in SHP may be necessary to improving the current level of implementation in the State.
Genetic toxicology in the 21st century: Reflections and future ...
A symposium at the 40th anniversary of the Environmental Mutagen Society, held from October 24–28, 2009 in St. Louis, MO, surveyed the current status and future directions of genetic toxicology. This article summarizes the presentations and provides a perspective on the future. An abbreviated history is presented, highlighting the current standard battery of genotoxicity assays and persistent challenges. Application of computational toxicology to safety testing within a regulatory setting is discussed as a means for reducing the need for animal testing and human clinical trials, and current approaches and applications of in silico genotoxicity screening approaches across the pharmaceutical industry were surveyed and are reported here. The expanded use of toxicogenomics to illuminate mechanisms and bridge genotoxicity and carcinogenicity, and new public efforts to use high-throughput screening technologies to address lack of toxicity evaluation for the backlog of thousands of industrial chemicals in the environment are detailed. The Tox21 project involves coordinated efforts of four U.S. Government regulatory/research entities to use new and innovative assays to characterize key steps in toxicity pathways, including genotoxic and nongenotoxic mechanisms for carcinogenesis. Progress to date, highlighting preliminary test results from the National Toxicology Program is summarized. Finally, an overview is presented of ToxCast™, a related research program of the
An overview of the regulation of influenza vaccines in the United States.
Weir, Jerry P; Gruber, Marion F
2016-09-01
Influenza virus vaccines are unique among currently licensed viral vaccines. The vaccines designed to protect against seasonal influenza illness must be updated periodically in an effort to match the vaccine strain with currently circulating viruses, and the vaccine manufacturing timeline includes multiple, overlapping processes with a very limited amount of flexibility. In the United States (U.S.), over 150 million doses of seasonal trivalent and quadrivalent vaccine are produced annually, a mammoth effort, particularly in the context of a vaccine with components that usually change on a yearly basis. In addition, emergence of an influenza virus containing an HA subtype that has not recently circulated in humans is an ever present possibility. Recently, pandemic influenza vaccines have been licensed, and the pathways for licensure of pandemic vaccines and subsequent strain updating have been defined. Thus, there are formidable challenges for the regulation of currently licensed influenza vaccines, as well as for the regulation of influenza vaccines under development. This review describes the process of licensing influenza vaccines in the U.S., the process and steps involved in the annual updating of seasonal influenza vaccines, and some recent experiences and regulatory challenges faced in development and evaluation of novel influenza vaccines. © 2016 The Authors.

Pilot projects and nation-wide immunization in India.
Haxton, D
1984-01-01
These studies identify possibilities for expanding immunization coverage in India and show that there have been positive experiences in going to scale with immunizationation at the district level. Reasons for success are discussed. The promotion of social awareness and participation through all available channels is of central importance. Continuing attention should be directed to vaccine supply and distribution systems, program management and manpower training, especially at the community level. There are many opportunities for extending involvement in immunization efforts and broad-spectrum programs beyond the confines of the health system, and for flexibility in program organization. Planning must incorporate political commitment as well as the provision of adequate financial resources. India launched the Expanded Program on Immunization (EPI) in 1978. 6 diseases are currently on the official schedule for progressive nation-wide immunization: tuberculosis, poliomyelitis, whooping cough, diptheria, tetanus and typhoid. The experiences of 3 efforts in Dewas, in Bidar, (2 rural areas), and in Delhi (an urban area) are covered. Immunization coverage before the intensive efforts did not exceed 30%. Major elements of program organization were: nonhealth sector political and administrative involvement from the state; multisectoral planning committees at different levels; household surveys to identify children to be immunized; training sessions for each category of workers; and strengthening the cold chain. Factors in operational design and implementation include: vaccination posts in the community; selection of acceptable vaccination days; reminders the day before vaccination; collection of children; immunization cards as a device for informing about next round; counteraction of side-effects; follow-up of drop-outs; monitoring for corrective action involving all participants; and formal evaluation by local medical colleges. Intensive immunization in the 3 pilot sites yielded significant improvements in immunization coverage, surpassing government targets and approaching or exceeding the objective of 80% immunization in most cases.
South Korean Family Caregiver Involvement in Delirium Care: A Qualitative Descriptive Study.
Kang, Yun; Moyle, Wendy; Cooke, Marie; O'Dwyer, Siobhan
2017-12-01
The current study aimed to describe the effect of an educational program on RN-initiated efforts to involve family caregivers in delirium care. A descriptive qualitative study was performed. A purposive sample of 12 RNs who participated in a one group, pre-post evaluation of a delirium educational program, and a nominated sample of six family caregivers of patients who had been cared for by RNs in the program participated in individual, in-depth interviews. The qualitative findings indicated that the inclusion of a delirium brochure in ward orientation on admission, with reinforcement during shift changes, and RN-initiated engagement with family caregivers promoted family caregiver involvement in delirium prevention. Further studies in South Korea are needed to determine which family-centered nursing care interventions are culturally appropriate and most effective for RNs and family caregivers in delirium care.

Jordan, E. H.; Walker, K. P.
1991-01-01
This report summarizes the result of research done under NASA NAG3-882 Nonlinear Mechanics of Composites with Periodic Microstructure. The effort involved the development of non-finite element methods to calculate local stresses around fibers in composite materials. The theory was developed and some promising numerical results were obtained. It is expected that when this approach is fully developed, it will provide an important tool for calculating local stresses and averaged constitutive behavior in composites. NASA currently has a major contractual effort (NAS3-24691) to bring the approach developed under this grant to application readiness. The report has three sections. One, the general theory that appeared as a NASA TM, a second section that gives greater details about the theory connecting Greens functions and Fourier series approaches, and a final section shows numerical results.
A retrospective perspective: evaluating population changes by repeating historic bird surveys
Igl, Lawrence D.; Johnson, Douglas H.
2005-01-01
Acquiring an accurate picture of the changes in bird populations often involves a tradeoff between the time and effort required to complete the surveys and the number of years spent surveying the bird populations. An alternative approach to long-term monitoring efforts is to collect current data and contrast those with data collected earlier in a similar fashion on the same study site(s). To evaluate changes in bird populations, we repeated two extensive surveys, one in North Dakota (1967 vs. 1992-1993) and the other in the Platte River Valley of Nebraska (1979-1980 vs. 2001), where large areas of native vegetation had been converted to agriculture. We use these examples and others from the literature to illustrate the advantages and disadvantages of using historical data as a frame of reference for population changes.
Bringing eCare platforms to the market.
Vannieuwenborg, Frederic; Van der Auwermeulen, Thomas; Van Ooteghem, Jan; Jacobs, An; Verbugge, Sofie; Colle, Didier
2017-09-01
Due to changes in the demographic situation of most Western European countries, interest in Information and Communication Technologies (ICT)-supported care services is growing fast. eCare services that foster better care information exchange, social involvement, lifestyle monitoring services, etc., offered via ICT platforms, integrated in the homes of the elderly are believed to be cost-effective. Additionally, they could lead to an increased quality of life of both care receiver and (in)formal caregiver. Currently, adoption and integration of these eCare platforms (eCPs) is slowed down by several barriers such as unclear added value, a lack of regulations, or lack of sustainable financial models. In this work, the added value of eCPs is identified for the several involved key actors such as the care receiver, the (in)formal care providers, and the home care organizations. In a second step, several go-to-market strategies are formulated. Because the gap between the current way of providing home care and providing home care supported by a fully integrated eCP seems too big to bridge in one effort, a migration path is provided for stepwise integration and adoption of eCPs in the current way of home care provisioning.

Researchers have begun to apply cognitive neuroscience concepts and methods to study behavior change mechanisms in alcohol use disorder (AUD) treatments. This review begins with an examination of the current state of treatment mechanisms research using clinical and social psychological approaches. It then summarizes what is currently understood about the pathophysiology of addiction from a cognitive neuroscience perspective. Finally, it reviews recent efforts to use cognitive neuroscience approaches to understand the neural mechanisms of behavior change in AUD, including studies that use neural functioning to predict relapse and abstinence; studies examining neural mechanisms that operate in current evidence-based behavioral interventions for AUD; as well as research on novel behavioral interventions that are being derived from our emerging understanding of the neural and cognitive mechanisms of behavior change in AUD. The article highlights how the regulation of subcortical regions involved in alcohol incentive motivation by prefrontal cortical regions involved in cognitive control may be a core mechanism that plays a role in these varied forms of behavior change in AUD. We also lay out a multilevel framework for integrating cognitive neuroscience approaches with more traditional methods for examining AUD treatment mechanisms.
Retinitis pigmentosa and allied conditions today: a paradigm of translational research
2010-01-01
Monogenic human retinal dystrophies are a group of disorders characterized by progressive loss of photoreceptor cells leading to visual handicap. Retinitis pigmentosa is a type of retinal dystrophy where degeneration of rod photoreceptors occurs at the early stages. At present, there are no available effective therapies to maintain or improve vision in patients affected with retinitis pigmentosa, but post-genomic studies are allowing the development of potential therapeutic approaches. This review summarizes current knowledge on genes that have been identified to be responsible for retinitis pigmentosa, the involvement of these genes in the different forms of the disorder, the role of the proteins encoded by these genes in retinal function, the utility of genotyping, and current efforts to develop novel therapies.

Hypoxia inducible factors in hepatocellular carcinoma
Chen, Chu; Lou, Tao
2017-01-01
Hepatocellular carcinoma is one of the most prevalent and lethal cancers with limited therapeutic options. Pathogenesis of this disease involves tumor hypoxia and the activation of hypoxia inducible factors. In this review, we describe the current understanding of hypoxia signaling pathway and summarize the expression, function and target genes of hypoxia inducible factors in hepatocellular carcinoma. We also highlight the recent progress in hypoxia-targeted therapeutic strategies in hepatocellular carcinoma and discuss further the future efforts for the study of hypoxia and/or hypoxia inducible factors in this deadly disease.

Towards vast libraries of scaffold-diverse, conformationally constrained oligomers.
Kodadek, Thomas; McEnaney, Patrick J
2016-05-04
There is great interest in the development of probe molecules and drug leads that would bind tightly and selectively to protein surfaces that are difficult to target with traditional molecules, such as those involved in protein-protein interactions. The currently available evidence suggests that this will require molecules that are larger and have quite different chemical properties than typical Lipinski-compliant molecules that target enzyme active sites. We describe here efforts to develop vast libraries of conformationally constrained oligomers as a potentially rich source of these molecules.

A better understanding of the attributes of patients who require more effort to manage may improve risk adjustment approaches and lead to more efficient resource allocation, improved patient care and health outcomes, and reduced burnout in primary care clinicians. To identify and characterize high-effort patients from the physician's perspective. Cohort study. Ninety-nine primary care physicians in an academic primary care network. From a list of 100 randomly selected patients in their panels, PCPs identified patients who required a high level of team-based effort and patients they considered complex. For high-effort patients, PCPs indicated which factors influenced their decision: medical/care coordination, behavioral health, and/or socioeconomic factors. We examined differences in patient characteristics based on PCP-defined effort and complexity. Among 9594 eligible patients, PCPs classified 2277 (23.7 %) as high-effort and 2676 (27.9 %) as complex. Behavioral health issues were the major driver of effort in younger patients, while medical/care coordination issues predominated in older patients. Compared to low-effort patients, high-effort patients were significantly (P < 0.01 for all) more likely to have higher rates of medical (e.g. 23.2 % vs. 6.3 % for diabetes) and behavioral health problems (e.g. 9.8 % vs. 2.9 % for substance use disorder), more frequent primary care visits (10.9 vs. 6.0 visits), and higher acute care utilization rates (25.8 % vs. 7.7 % for emergency department [ED] visits and 15.0 % vs. 3.9 % for hospitalization). Almost one in five (18 %) patients who were considered high-effort were not deemed complex by the same PCPs. Patients defined as high-effort by their primary care physicians, not all of whom were medically complex, appear to have a high burden of psychosocial issues that may not be accounted for in current chronic disease-focused risk adjustment approaches.

Chemical Warfare and Medical Response During World War I
Fitzgerald, Gerard J.
2008-01-01
The first large-scale use of a traditional weapon of mass destruction (chemical, biological, or nuclear) involved the successful deployment of chemical weapons during World War I (1914–1918). Historians now refer to the Great War as the chemist’s war because of the scientific and engineering mobilization efforts by the major belligerents. The development, production, and deployment of war gases such as chlorine, phosgene, and mustard created a new and complex public health threat that endangered not only soldiers and civilians on the battlefield but also chemical workers on the home front involved in the large-scale manufacturing processes. The story of chemical weapons research and development during that war provides useful insights for current public health practitioners faced with a possible chemical weapons attack against civilian or military populations.

Theories on the pathogenesis of endometriosis.
Sourial, Samer; Tempest, Nicola; Hapangama, Dharani K
2014-01-01
Endometriosis is a common, chronic inflammatory disease defined by the presence of extrauterine endometrial tissue. The aetiology of endometriosis is complex and multifactorial, where several not fully confirmed theories describe its pathogenesis. This review examines existing theories on the initiation and propagation of different types of endometriotic lesions, as well as critically appraises the myriad of biologically relevant evidence that support or oppose each of the proposed theories. The current literature suggests that stem cells, dysfunctional immune response, genetic predisposition, and aberrant peritoneal environment may all be involved in the establishment and propagation of endometriotic lesions. An orchestrated scientific and clinical effort is needed to consider all factors involved in the pathogenesis of this multifaceted disease and to propose novel therapeutic targets to reach effective treatments for this distressing condition.
Inner rehearsal modeling for cognitive robotics
NASA Astrophysics Data System (ADS)
Braun, Jerome J.; Bergen, Karianne; Dasey, Timothy J.
2011-05-01
This paper presents a biomimetic approach involving cognitive process modeling, for use in intelligent robot decisionmaking. The principle of inner rehearsal, a process believed to occur in human and animal cognition, involves internal rehearsing of actions prior to deciding on and executing an overt action, such as a motor action. The inner-rehearsal algorithmic approach we developed is posed and investigated in the context of a relatively complex cognitive task, an under-rubble search and rescue. The paper presents the approach developed, a synthetic environment which was also developed to enable its studies, and the results to date. The work reported here is part of a Cognitive Robotics effort in which we are currently engaged, focused on exploring techniques inspired by cognitive science and neuroscience insights, towards artificial cognition for robotics and autonomous systems.
Primer: establishing a clinical trial unit--obtaining studies and patients.
Fleischmann, Roy
2007-08-01
Rheumatologists with clinical expertise should perform clinical investigations of new molecules in an effort to discover therapies that could be of greater benefit or safety than those currently available for patients with chronic rheumatic diseases. Over the past few years, many studies have been conducted outside the United States and Europe because of the dearth of investigative sites in these countries. A clinician, whether in private practice or academia, who has the resources and desire to conduct clinical investigations, should be able to become involved in the process. The task of starting a new investigative unit is daunting, as it involves acquiring studies, hiring staff and obtaining space prior to any cash flow. If done properly, however, clinical investigation can be rewarding--both intellectually and financially.

Gender differences in elementary school performance among immigrant children have not yet been well documented. This study examined how differences in parental involvement, child effort, and family characteristics and resources contribute to immigrant boys’-and girls’ academic achievement from kindergarten through 5th-grade. The sample was drawn from the Early Childhood Longitudinal Study-Kindergarten cohort. Using a latent score growth model, this study found that parents’ involvement at home benefited boys’ reading and mathematics skills throughout all early elementary school years, but did not have the same benefit for girls. For both boys and girls, child effort in reading appears to be strongly linked to better reading and mathematics skills at kindergarten and to subsequent improvement between grades. The positive associations of parental involvement and child’s effort with test scores were greater during earlier years than during later years for boys, whereas there was no difference in the association over time for girls.

Gene Therapy Models of Alzheimer’s Disease and Other Dementias
Combs, Benjamin; Kneynsberg, Andrew; Kanaan, Nicholas M.
2016-01-01
Dementias are among the most common neurological disorders, and Alzheimer’s disease (AD) is the most common cause of dementia worldwide. AD remains a looming health crisis despite great efforts to learn the mechanisms surrounding the neuron dysfunction and neurodegeneration that accompanies AD primarily in the medial temporal lobe. In addition to AD, a group of diseases known as frontotemporal dementias (FTDs) are degenerative diseases involving atrophy and degeneration in the frontal and temporal lobe regions. Importantly, AD and a number of FTDs are collectively known as tauopathies due to the abundant accumulation of pathological tau inclusions in the brain. The precise role tau plays in disease pathogenesis remains an area of strong research focus. A critical component to effectively study any human disease is the availability of models that recapitulate key features of the disease. Accordingly, a number of animal models are currently being pursued to fill the current gaps in our knowledge of the causes of dementias and to develop effective therapeutics. Recent developments in gene therapy-based approaches, particularly in recombinant adeno-associated viruses (rAAVs), have provided new tools to study AD and other related neurodegenerative disorders. Additionally, gene therapy approaches have emerged as an intriguing possibility for treating these diseases in humans. This chapter explores the current state of rAAV models of AD and other dementias, discuss recent efforts to improve these models, and describe current and future possibilities in the use of rAAVs and other viruses in treatments of disease.

Nerve Agents: What They Are, How They Work, How to Counter Them.
Costanzi, Stefano; Machado, John-Hanson; Mitchell, Moriah

Nerve agents are organophosphorus chemical warfare agents that exert their action through the irreversible inhibition of acetylcholinesterase, with a consequent overstimulation of cholinergic transmission followed by its shutdown. Beyond warfare, they have notoriously been employed in acts of terrorism as well as high profile assassinations. After a brief historical introduction on the development and deployment of nerve agents, this review provides a survey of their chemistry, the way they affect cholinergic transmission, the available treatment options, and the current directions for their improvement. As the review illustrates, despite their merits, the currently available treatment options present several shortcomings. Current research directions involve the search for improved antidotes, antagonists of the nicotinic receptors, small-molecule pretreatment options, as well as bioscavengers as macromolecular pretreatment options. These efforts are making good progress in many different directions and, hopefully, will lead to a lower target susceptibility, thus reducing the appeal of nerve agents as chemical weapons.

Background Street-involved youth are a population at risk of adopting injection as a route of administration, and preventing the transition to injection drug use among street youth represents a public health priority. In order to inform epidemiological research and prevention efforts, we conducted a qualitative study to investigate the initiation of injection drug use among street-involved youth in Vancouver, Canada. Methods Qualitative interviews with street youth who inject drugs elicited descriptions of the adoption of injection as a route of administration. Interviewees were recruited from the At-Risk Youth Study (ARYS), a cohort of street-involved youth who use illicit drugs in Vancouver, Canada. Audio recorded interviews were transcribed verbatim and a thematic analysis was conducted. Results 26 youth aged 16 to 26 participated in this study, including 12 females. Among study participants the first injection episode frequently featured another drug user who facilitated the initiation of injecting. Youth narratives indicate that the transition into injecting is influenced by social interactions with drug using peers and evolving perceptions of injecting, and rejecting identification as an injector was important among youth who did not continue to inject. It appears that social conventions discouraging initiating young drug users into injection exist among established injectors, although this ethic is often ignored. Conclusion The importance of social relationships with other drug users within the adoption of injection drug use highlights the potential of social interventions to prevent injection initiation. Additionally, developing strategies to engage current injectors who are likely to initiate youth into injection could also benefit prevention efforts. PMID:19405977

Background Pharmacotherapy – methadone, buprenorphine, or naltrexone – is an evidence-based treatment for opioid use disorder, but little is known about receipt of these medications among veterans involved in the justice system. The current study examines receipt of pharmacotherapy for opioid use disorder among veterans with a history of justice involvement at U.S. Veterans Health Administration (VHA) facilities compared to veterans with no justice involvement. Methods Using national VHA clinical and pharmacy records, we conducted a retrospective cohort study of veterans with an opioid use disorder diagnosis in fiscal year 2012. Using a mixed-effects logistic regression model, we examined receipt of pharmacotherapy in the 1-year period following diagnosis as a function of justice involvement, adjusting for patient and facility characteristics. Results The 1-year rate of receipt for pharmacotherapy for opioid use disorder was 27% for prison-involved veterans, 34% for jail/court-involved veterans, and 33% for veterans not justice-involved. Compared to veterans not justice-involved, those prison-involved had 0.75 lower adjusted odds (95% confidence interval [CI]: 0.65–0.87) of receiving pharmacotherapy whereas jail/court-involved veterans did not have significantly different adjusted odds. Conclusions Targeted efforts to increase receipt of pharmacotherapy for opioid use disorder among veterans exiting prison is needed as they have lower odds of receiving these medications.

RNA interference (RNAi), is a powerful new technology in the discovery of genetic sequence functions, and has become a valuable tool for functional genomics of cotton (Gossypium sp.). The rapid adoption of RNAi has replaced previous antisense technology. RNAi has aided in the discovery of function and biological roles of many key cotton genes involved in fiber development, fertility and somatic embryogenesis, resistance to important biotic and abiotic stresses, and oil and seed quality improvements as well as the key agronomic traits including yield and maturity. Here, we have comparatively reviewed seminal research efforts in previously used antisense approaches and currently applied breakthrough RNAi studies in cotton, analyzing developed RNAi methodologies, achievements, limitations, and future needs in functional characterizations of cotton genes. We also highlighted needed efforts in the development of RNAi-based cotton cultivars, and their safety and risk assessment, small and large-scale field trials, and commercialization. PMID:26941765
THE CHALLENGING ROLE OF A READING COACH, A CAUTIONARY TALE.

2008-04-01
The purpose of this case study is to describe the challenges one coach faced during the initial implementation of a coaching initiative involving 33 teachers in an urban, high-poverty elementary school. Reading coaches are increasingly expected to play a key role in the professional development efforts to improve reading instruction in order to improve reading achievement for struggling readers. Data sources included initial reading scores for kindergarten and first-graders, pretest and posttest scores of teachers' knowledge, a teacher survey, focus group interviews, project documents, and field notes. Data were analyzed using a mixed methods approach. Findings revealed several challenges that have important implications for research and practice: that teachers encountered new information about teaching early reading that conflicted with their current knowledge, this new information conflicted with their core reading program, teachers had differing perceptions of the role of the reading coach that affected their feelings about the project, and reform efforts are time-intensive.

Urban water planning, development, and management are many sectored, costly efforts, subject to a multitude of controls and demands including those imposed by nature. One primary concern in development is for providing a dependable and safe water supply. In spite of a bountiful natural availability, the process of satisfying consumer needs involves the resolution of a variety of problems, not the least of which are cooperation and coordination among suppliers. One of the fundamental requisites in seeking sound solutions to developmental and environmental problems is inventory documentation. This map is one facet of documentation; the data listing, given on sheet 2, is the companion inventory. These supplement State, regional, and local efforts directed toward both long-range planning and current evaluation programs. Such documentation also assists the assessment of the effect of one water-management subsystem on hydrologic characteristics.

Plasma surface interactions in fusion tokamak reactors involve an inherently multiscale, highly non-equilibrium set of phenomena, for which current models are inadequate to predict the divertor response to and feedback on the plasma. In this presentation, we describe the latest code developments of Xolotl, a spatially-dependent reaction diffusion cluster dynamics code to simulate the divertor surface response to fusion-relevant plasma exposure. Xolotl is part of a code-coupling effort to model both plasma and material simultaneously; the first benchmark for this effort is the series of PISCES linear device experiments. We will discuss the processes leading to surface morphology changes, which further affect erosion, as well as how Xolotl has been updated in order to communicate with other codes. Furthermore, we will show results of the sub-surface evolution of helium bubbles in tungsten as well as the material surface displacement under these conditions.

One of the most important drawbacks which caused the silicon based technologies to their technical limitations is the instability of their products at nano-level. On the other side, carbon based materials such as carbon nanotube (CNT) as alternative materials have been involved in scientific efforts. Some of the important advantages of CNTs over silicon components are high mechanical strength, high sensing capability and large surface-to-volume ratio. In this article, the model of CNT Schottky transistor current which is under exterior applied voltage is employed. This model shows that its current has a weak dependence on thermal velocity corresponding to themore » small applied voltage. The conditions are quite different for high bias voltages which are independent of temperature. Our results indicate that the current is increased by Fermi velocity, but the I–V curves will not have considerable changes with the variations in number of carriers. It means that the current doesn’t increase sharply by voltage variations over different number of carriers.« less

Design of offshore drilling equipment is a task that involves not only analysis of strict machine specifications and safety requirements but also consideration of changeable weather conditions and harsh environment. These challenges call for a multidisciplinary approach and make the design process complex. Various modeling software products are currently available to aid design engineers in their effort to test and redesign equipment before it is manufactured. However, given the number of available modeling tools and methods, the choice of the proper modeling methodology becomes not obvious and – in some cases – troublesome. Therefore, we present a comparative analysis ofmore » two popular approaches used in modeling and simulation of mechanical systems: multibody and analytical modeling. A gripper arm of the offshore vertical pipe handling machine is selected as a case study for which both models are created. In contrast to some other works, the current paper shows verification of both systems by benchmarking their simulation results against each other. Such criteria as modeling effort and results accuracy are evaluated to assess which modeling strategy is the most suitable given its eventual application.« less
Magnetic Suspension Technology Development

1998-01-01
This Cooperative Agreement, intended to support focused research efforts in the area of magnetic suspension systems, was initiated between NASA Langley Research Center (LaRC) and Old Dominion University (ODU) starting January 1, 1997. The original proposal called for a three-year effort, but funding for the second year proved to be unavailable, leading to termination of the agreement following a 5-month no-cost extension. This report covers work completed during the entire 17-month period of the award. This research built on work that had taken place over recent years involving both NASA LARC and the Principal Investigator (PI). The research was of a rather fundamental nature, although specific applications were kept in mind at all times, such as wind tunnel Magnetic Suspension and Balance Systems (MSBS), space payload pointing and vibration isolation systems, magnetic bearings for unconventional applications, magnetically levitated ground transportation and electromagnetic launch systems. Fundamental work was undertaken in areas such as the development of optimized magnetic configurations, analysis and modelling of eddy current effects, control strategies for magnetically levitated wind tunnel models and system calibration procedures. Despite the termination of this Cooperative Agreement, several aspects of the research work are currently continuing with alternative forms of support.

The U.S. Department of Energy sponsors the Advanced Test Reactor (ATR) National Scientific User Facility (NSUF) program to promote U.S. research in nuclear science and technology. By attracting new research users - universities, laboratories, and industry - the ATR NSUF facilitates basic and applied nuclear research and development, advancing U.S. energy security needs. A key component of the ATR NSUF effort is to design, develop, and deploy new in-pile instrumentation techniques that are capable of providing real-time measurements of key parameters during irradiation. This paper describes the strategy developed by the Idaho National Laboratory (INL) for identifying instrumentation needed for ATR irradiation tests and the program initiated to obtain these sensors. New sensors developed from this effort are identified, and the progress of other development efforts is summarized. As reported in this paper, INL researchers are currently involved in several tasks to deploy real-time length and flux detection sensors, and efforts have been initiated to develop a crack growth test rig. Tasks evaluating `advanced' technologies, such as fiber-optics based length detection and ultrasonic thermometers, are also underway. In addition, specialized sensors for real-time detection of temperature and thermal conductivity are not only being provided to NSUF reactors, but are also being provided to several international test reactors.
On the lack of consensus over the meaning of openness: an empirical study.
Grubb, Alicia M; Easterbrook, Steve M
2011-01-01
This study set out to explore the views and motivations of those involved in a number of recent and current advocacy efforts (such as open science, computational provenance, and reproducible research) aimed at making science and scientific artifacts accessible to a wider audience. Using a exploratory approach, the study tested whether a consensus exists among advocates of these initiatives about the key concepts, exploring the meanings that scientists attach to the various mechanisms for sharing their work, and the social context in which this takes place. The study used a purposive sampling strategy to target scientists who have been active participants in these advocacy efforts, and an open-ended questionnaire to collect detailed opinions on the topics of reproducibility, credibility, scooping, data sharing, results sharing, and the effectiveness of the peer review process. We found evidence of a lack of agreement on the meaning of key terminology, and a lack of consensus on some of the broader goals of these advocacy efforts. These results can be explained through a closer examination of the divergent goals and approaches adopted by different advocacy efforts. We suggest that the scientific community could benefit from a broader discussion of what it means to make scientific research more accessible and how this might best be achieved.

Adaptive behaviour entails the capacity to select actions as a function of their energy cost and expected value and the disruption of this faculty is now viewed as a possible cause of the symptoms of Parkinson's disease. Indirect evidence points to the involvement of the subthalamic nucleus-the most common target for deep brain stimulation in Parkinson's disease-in cost-benefit computation. However, this putative function appears at odds with the current view that the subthalamic nucleus is important for adjusting behaviour to conflict. Here we tested these contrasting hypotheses by recording the neuronal activity of the subthalamic nucleus of patients with Parkinson's disease during an effort-based decision task. Local field potentials were recorded from the subthalamic nucleus of 12 patients with advanced Parkinson's disease (mean age 63.8 years ± 6.8; mean disease duration 9.4 years ± 2.5) both OFF and ON levodopa while they had to decide whether to engage in an effort task based on the level of effort required and the value of the reward promised in return. The data were analysed using generalized linear mixed models and cluster-based permutation methods. Behaviourally, the probability of trial acceptance increased with the reward value and decreased with the required effort level. Dopamine replacement therapy increased the rate of acceptance for efforts associated with low rewards. When recording the subthalamic nucleus activity, we found a clear neural response to both reward and effort cues in the 1-10 Hz range. In addition these responses were informative of the subjective value of reward and level of effort rather than their actual quantities, such that they were predictive of the participant's decisions. OFF levodopa, this link with acceptance was weakened. Finally, we found that these responses did not index conflict, as they did not vary as a function of the distance from indifference in the acceptance decision. These findings show that low-frequency neuronal activity in the subthalamic nucleus may encode the information required to make cost-benefit comparisons, rather than signal conflict. The link between these neural responses and behaviour was stronger under dopamine replacement therapy. Our findings are consistent with the view that Parkinson's disease symptoms may be caused by a disruption of the processes involved in balancing the value of actions with their associated effort cost. © The Author (2016).

Corticosterone mediated costs of reproduction link current to future breeding.
Crossin, Glenn T; Phillips, Richard A; Lattin, Christine R; Romero, L Michael; Williams, Tony D
2013-11-01
Life-history theory predicts that costs are associated with reproduction. One possible mediator of costs involves the secretion of glucocorticoid hormones, which in birds can be measured in feathers grown during the breeding period. Glucocorticoids mediate physiological responses to unpredictable environmental or other stressors, but they can also function as metabolic regulators during more predictable events such as reproduction. Here we show that corticosterone ("Cort") in feathers grown during the breeding season reflects reproductive effort in two Antarctic seabird species (giant petrels, Macronectes spp.). In females of both species, but not males, feather Cort ("fCort") was nearly 1.5-fold higher in successful than failed breeders (those that lost their eggs/chicks), suggesting a cost of successful reproduction, i.e., high fCort levels in females reflect the elevated plasma Cort levels required to support high metabolic demands of chick-rearing. Successful breeding also led to delayed moult prior to winter migration. The fCort levels and pre-migration moult score that we measured at the end of current breeding were predictive of subsequent reproductive effort in the following year. Birds with high fCort and a delayed initiation of moult were much more likely to defer breeding in the following year. Cort levels and the timing of moult thus provide a potential mechanism for the tradeoff between current and future reproduction. Crown Copyright © 2013. Published by Elsevier Inc.

The state of shared decision making in Malaysia.
Lee, Yew Kong; Ng, Chirk Jenn
2017-06-01
Shared decision making (SDM) activities in Malaysia began around 2010. Although the concept is not widespread, there are opportunities to implement SDM in both the public and private healthcare sectors. Malaysia has a multicultural society and cultural components (such as language differences, medical paternalism, strong family involvement, religious beliefs and complementary medicine) influence medical decision making. In terms of policy, the Ministry of Health has increasingly mentioned patient-centered care as a component of healthcare delivery while the Malaysian Medical Council's guidelines on doctors' duties mentioned collaborative partnerships as a goal of doctor-patient relationships. Current research on SDM comprises baseline surveys of decisional role preferences, development and implementation of locally developed patient decision aids, and conducting of SDM training workshops. Most of this research is carried out by public research universities. In summary, the current state of SDM in Malaysia is still at its infancy. However, there are increasing recognition and efforts from the academic institutions and Ministry of Health to conduct research in SDM, develop patient decision support tools and initiate national discussion on patient involvement in decision making.

A hemolysis-linked subphenotype of sickle cell disease (SCD), characterized by pulmonary hypertension, stroke, priapism and leg ulcers, is associated with decreased nitric oxide bioavailability and vasculopathy. Vasculopathy appears to have a multifactorial etiology, including mechanisms primarily that involve deficient nitric oxide (NO) signaling, but also involving altered function of NO synthase related to substrate availability and cooperating factors such as apolipoproteins. Improved understanding of the vascular pathophysiology of SCD has led to new vascular targets for translational research in SCD. This growing vascular therapeutics field in SCD is complementary to the ongoing efforts to reduce the morbidity of vaso-occlusive pain crisis. This presentation will review the current biology and translational clinical development of novel small molecules targeting sickle cell vasculopathy. Strategies targeting the heme-oxygenase-carbon monoxide pathway, the arginine-NO synthase-cGMP-phosphodiesterase 5 pathway, the nitrate-nitrite-NO pathway, and the apolipoprotein A-I pathways will be reviewed. In this context, current clinical trials of inhaled NO, CO, nitrite, sildenafil and apoA-I mimetics will be discussed. PMID:19074079
Powering Up: Assessing the growing municipal energy resilience building efforts in North America
NASA Astrophysics Data System (ADS)
Schimmelfing, Kara
Energy related shortages and price volatilities can impact all levels of society. With coming fossil fuel depletion related to peak oil, it is expected these shortages and volatilities will increase in frequency, duration, and intensity. Resilience building is a strategy to minimize the effects of these events by modifying systems so they are less impacted and/or recover more quickly from disruptive events. Resilience building is being used, particularly at the municipal scale, to prepare for these coming energy related changes. These municipal efforts have only been in existence for five to ten years, and full implementation is still in progress. Little evaluation has been done of these municipal efforts to date, particularly in North America. Despite this, it is important to begin to assess the effectiveness of these efforts now. As a result, future efforts can be redirected to address weak areas and that lessons learned by vanguard communities can be applied in other communities attempting to build energy resilience in the future. This thesis involved the creation of a hybrid framework to evaluate municipal energy resilience building efforts. The framework drew primarily from planning process and factors identified as important to build resilience in social-ecological systems. It consisted of the following categories to group resilience building efforts: Economy, Resource Systems & Infrastructure, Public Awareness, Social Services, Transportation, Built Environment, and Natural Environment. Within these categories the following process steps should be observed: Context, Goals, Needs, Processes, and Outcomes. This framework was then tested through application to four case-study communities (Bloomington, IN, Hamilton, ON, Oakland, CA, Victoria, BC) currently pursuing energy resilience building efforts in North America. This qualitative research involved document analysis primarily of municipal documents related to energy planning efforts. Supplementary interviews were also conducted to verify the findings from the documents and illuminate anything not captured by them. Once data was collected, categorized and analyzed using the framework, comparisons were made between case-studies. Results showed the framework to be a successful, but time consuming, tool for assessing municipal energy resilience building. Four revisions are recommended for the framework before further research. Analysis of the case study communities' efforts also identified five factors for recommended for other communities attempting energy resilience planning at the municipal scale: consistent support from within the municipality, integration and information sharing, presence of key resources, access to information on energy use, and a two-tier planning process. Ultimately, as this is a preliminary attempt to address a young and growing area of municipal effort, there are many avenues for further research to build on the work of this thesis.

A key component of many monitoring programs for special status species involves capture and handling of individuals as part of capture-recapture efforts for tracking population health and demography. Minimizing negative impacts from sampling, such as through reduced handling, aids prevention of negative impacts on species from monitoring efforts. Using simulation analyses, we found that long-term population monitoring techniques, requiring physical capture (i.e. hoop-net sampling), can be reduced and supplemented with passive detections (i.e. PIT tag antenna array detections) without negatively affecting estimates of adult humpback chub (HBC; Gila cypha) survival (S) and skipped spawning probabilities (γ' = spawner transitions to a skipped spawner, γ′ = skipped spawner remains a skipped spawner). Based on our findings of the array’s in situ detection efficiency (0.42), estimability of such demographic parameters would improve over hoop-netting alone. In addition, the array provides insight into HBC population dynamics and movement patterns outside of traditional sampling periods. However, given current timing of sampling efforts, spawner abundance estimates were negatively biased when hoop-netting was reduced, suggesting not all spawning HBC are present during the current sampling events. Despite this, our findings demonstrate that PIT tag antenna arrays, even with moderate potential detectability, may allow for reduced handling of special status species while also offering potentially more efficient monitoring strategies, especially if ideal timing of sampling can be determined.
[Involving patients, the insured and the general public in healthcare decision making].
Mühlbacher, Axel C; Juhnke, Christin
2016-01-01
No doubt, the public should be involved in healthcare decision making, especially when decision makers from politics and self-government agencies are faced with the difficult task of setting priorities. There is a general consensus on the need for a stronger patient centeredness, even in HTA processes, and internationally different ways of public participation are discussed and tested in decision making processes. This paper describes how the public can be involved in different decision situations, and it shows how preference measurement methods are currently being used in an international context to support decision making. It distinguishes between different levels of decision making on health technologies: approval, assessment, pricing, and finally utilization. The range of participation efforts extends from qualitative surveys of patients' needs (Citizen Councils of NICE in the UK) to science-based documentation of quantitative patient preferences, such as in the current pilot projects of the FDA in the US and the EMA at the European level. Possible approaches for the elicitation and documentation of preference structures and trade-offs in relation to alternate health technologies are decision aids, such as multi-criteria decision analysis (MCDA), that provide the necessary information for weighting and prioritizing decision criteria.

Fungi play important roles across the range of current and future biofuel production processes. From crop/feedstock health to plant biomass saccharification, enzyme production to bioprocesses for producing ethanol, higher alcohols or future hydrocarbon biofuels, fungi are involved. Research and development are underway to understand the underlying biological processes and improve them to make bioenergy production efficient on an industrial scale. Genomics is the foundation of the systems biology approach that is being used to accelerate the research and development efforts across the spectrum of topic areas that impact biofuels production. In this review, we discuss past, current and future advancesmore » made possible by genomic analyses of the fungi that impact plant/feedstock health, degradation of lignocellulosic biomass and fermentation of sugars to ethanol, hydrocarbon biofuels and renewable chemicals.« less
Prediction of Metabolism of Drugs using Artificial Intelligence: How far have we reached?
Kumar, Rajnish; Sharma, Anju; Siddiqui, Mohammed Haris; Tiwari, Rajesh Kumar
2016-01-01
Information about drug metabolism is an essential component of drug development. Modeling the drug metabolism requires identification of the involved enzymes, rate and extent of metabolism, the sites of metabolism etc. There has been continuous attempts in the prediction of metabolism of drugs using artificial intelligence in effort to reduce the attrition rate of drug candidates entering to preclinical and clinical trials. Currently, there are number of predictive models available for metabolism using Support vector machines, Artificial neural networks, Bayesian classifiers etc. There is an urgent need to review their progress so far and address the existing challenges in prediction of metabolism. In this attempt, we are presenting the currently available literature models and some of the critical issues regarding prediction of drug metabolism.

Healthcare institutions face high levels of risk on a daily basis. Efforts have been made to address these risks and turn this complex environment into a safer environment for patients, staff, and visitors. However, healthcare institutions need more advanced risk management tools to achieve the safety levels currently seen in other industries. One of these potential tools is occurrence investigation systems. In order to be investigated, occurrences must be detected and selected for investigation, since not all institutions have enough resources to investigate all occurrences. A survey was conducted in healthcare institutions in Canada and Brazil to evaluate currently used risk management tools, the difficulties faced, and the possibilities for improvement. The findings include detectability difficulties, lack of resources, lack of support, and insufficient staff involvement.

Integrating costs and benefits is crucial for optimal decision-making. Although much is known about decisions that involve outcome-related costs (e.g., delay, risk), many of our choices are attached to actions and require an evaluation of the associated motor costs. Yet how the brain incorporates motor costs into choices remains largely unclear. We used human fMRI during choices involving monetary reward and physical effort to identify brain regions that serve as a choice comparator for effort-reward trade-offs. By independently varying both options' effort and reward levels, we were able to identify the neural signature of a comparator mechanism. A network involving supplementary motor area and the caudal portion of dorsal anterior cingulate cortex encoded the difference in reward (positively) and effort levels (negatively) between chosen and unchosen choice options. We next modeled effort-discounted subjective values using a novel behavioral model. This revealed that the same network of regions involving dorsal anterior cingulate cortex and supplementary motor area encoded the difference between the chosen and unchosen options' subjective values, and that activity was best described using a concave model of effort-discounting. In addition, this signal reflected how precisely value determined participants' choices. By contrast, separate signals in supplementary motor area and ventromedial prefrontal cortex correlated with participants' tendency to avoid effort and seek reward, respectively. This suggests that the critical neural signature of decision-making for choices involving motor costs is found in human cingulate cortex and not ventromedial prefrontal cortex as typically reported for outcome-based choice. Furthermore, distinct frontal circuits seem to drive behavior toward reward maximization and effort minimization. SIGNIFICANCE STATEMENT The neural processes that govern the trade-off between expected benefits and motor costs remain largely unknown. This is striking because energetic requirements play an integral role in our day-to-day choices and instrumental behavior, and a diminished willingness to exert effort is a characteristic feature of a range of neurological disorders. We use a new behavioral characterization of how humans trade off reward maximization with effort minimization to examine the neural signatures that underpin such choices, using BOLD MRI neuroimaging data. We find the critical neural signature of decision-making, a signal that reflects the comparison of value between choice options, in human cingulate cortex, whereas two distinct brain circuits drive behavior toward reward maximization or effort minimization.

Automated Work Package: Conceptual Design and Data Architecture
DOE Office of Scientific and Technical Information (OSTI.GOV)
Al Rashdan, Ahmad; Oxstrand, Johanna; Agarwal, Vivek
The automated work package (AWP) is one of the U.S. Department of Energy’s (DOE) Light Water Reactor Sustainability Program efforts to enhance the safety and economics of the nuclear power industry. An AWP is an adaptive and interactive work package that intelligently drives the work process according to the plant condition, resources status, and users progress. The AWP aims to automate several manual tasks of the work process to enhance human performance and reduce human errors. Electronic work packages (eWPs), studied by the Electric Power Research Institute (EPRI), are work packages that rely to various extent on electronic data processingmore » and presentation. AWPs are the future of eWPs. They are envisioned to incorporate the advanced technologies of the future, and thus address the unresolved deficiencies associated with the eWPs in a nuclear power plant. In order to define the AWP, it is necessary to develop an ideal envisioned scenario of the future work process without any current technology restriction. The approach followed to develop this scenario is specific to every stage of the work process execution. The scenario development resulted in fifty advanced functionalities that can be part of the AWP. To rank the importance of these functionalities, a survey was conducted involving several U.S. nuclear utilities. The survey aimed at determining the current need of the nuclear industry with respect to the current work process, i.e. what the industry is satisfied with, and where the industry envisions potential for improvement. The survey evaluated the most promising functionalities resulting from the scenario development. The results demonstrated a significant desire to adopt the majority of these functionalities. The results of the survey are expected to drive the Idaho National Laboratory (INL) AWP research and development (R&D). In order to facilitate this mission, a prototype AWP is needed. Since the vast majority of earlier efforts focused on the frontend aspects of the AWP, the backend data architecture was researched and developed in this effort. The backend design involved data architecture aspects. It was realized through this effort that the key aspects of this design are hierarchy, data configuration and live information, data templates and instances, the flow of work package execution, the introduction of properties, and the means to interface the backend to the frontend. After the backend design was developed, a data structure was built to reflect the developed data architecture. The data structure was developed to accommodate the fifty functionalities identified by the envisioned scenario development. The data structure was evaluated by incorporating an example work order from the nuclear power industry. The implementation resulted in several optimization iterations of the data structure. In addition, the rearrangement of the work order information to fit the data structure highlighted several possibilities for improvement in the current work order design, and significantly reduced the size of the work order.« less
Effort Thrombosis Presenting as Pulmonary Embolism in a Professional Baseball Pitcher
Bushnell, Brandon D.; Anz, Adam W.; Dugger, Keith; Sakryd, Gary A.; Noonan, Thomas J.
2009-01-01
Context: Effort thrombosis, or Paget-Schroetter’s syndrome, is a rare subset of thoracic outlet syndrome in which deep venous thrombosis of the upper extremity occurs as the result of repetitive overhead motion. It is occasionally associated with pulmonary embolism. This case of effort thrombosis and pulmonary embolus was in a 25-year-old major league professional baseball pitcher, in which the only presenting complaints involved dizziness and shortness of breath without complaints involving the upper extremity—usually, a hallmark of most cases of this condition. The patient successfully returned to play for 5 subsequent seasons at the major league level after multimodal treatment that included surgery for thoracic outlet syndrome. Objective: Though rare, effort thrombosis should be included in the differential diagnosis of throwing athletes with traditional extremity-focused symptoms and in cases involving pulmonary or thoracic complaints. Rapid diagnosis is a critical component of successful treatment. PMID:23015912
Scalar implicatures: working memory and a comparison with only
Marty, Paul P.; Chemla, Emmanuel
2013-01-01
A Scalar Implicature (SI) arises when the use of a relatively weak sentence (e.g., some politicians are corrupt) implies the denial of an alternative, stronger sentence (e.g., not all politicians are corrupt). The cognitive effort associated with the processing of SIs involves central memory resources (De Neys and Schaeken, 2007; Dieussaert et al., 2011; Marty et al., 2013). The goal of this study is to locate this previous result within the current psycholinguistic debate, and to understand at which level of SI processing these resources are specifically involved. Using a dual-task approach, we show that (1) tapping participant's memory resources interferes with the derivation of SIs, whereas (2) it does not affect the interpretation of sentences involving similar competition mechanisms between a sentence and potential alternatives through the use of only (e.g., only some politicians are corrupt). We explain how these findings suggest that the central memory resources are not involved in the core process at the source of SIs, and discuss how this difference between SIs and only bears on recent linguistic debates on the division of labor between grammar and pragmatics.

A remote sensing analysis of the amount and type of permeable and impermeable surfaces overlying an urban recharge basin is discussed. An effective methodology for accurately generating this data as input to a safe yield study is detailed and compared to more conventional alternative approaches. The amount of area inventoried, approximately 10 sq. miles, should provide a reliable base against which automatic pattern recognition algorithms, currently under investigation for this task, can be evaluated. If successful, such approaches can significantly reduce the time and effort involved in obtaining permeability data, an important aspect of urban hydrology dynamics.

The initial goal was to evaluate the capabilities of current pattern recognition techniques when applied to existing computerized crime data. Performance was to be evaluated both in terms of the system's capability to predict crimes and to optimize police manpower allocation. A relation was sought to predict the crime's susceptibility to solution, based on knowledge of the crime type, location, time, etc. The preliminary results of this work are discussed. They indicate that automatic crime analysis involving pattern recognition techniques is feasible, and that efforts to determine optimum variables and techniques are warranted. 47 figures (RWR)
Human-computer interaction in multitask situations

Rouse, W. B.
1977-01-01
Human-computer interaction in multitask decisionmaking situations is considered, and it is proposed that humans and computers have overlapping responsibilities. Queueing theory is employed to model this dynamic approach to the allocation of responsibility between human and computer. Results of simulation experiments are used to illustrate the effects of several system variables including number of tasks, mean time between arrivals of action-evoking events, human-computer speed mismatch, probability of computer error, probability of human error, and the level of feedback between human and computer. Current experimental efforts are discussed and the practical issues involved in designing human-computer systems for multitask situations are considered.
[Biotechnological functional systems].
Bokser, O Ia
1999-01-01
Based on the theory of functional systems and a concept of the quantum system of behavior, studies of the quantumsystems were conducted. Their structure, the interaction of biological and technical sections were analyzed. Mathematical, biophysical, and experimental models were designed. The paper shows that biotechnical quantumsystems are involved in the formation of biological feedback. A system with imperative feedback from the programmed and introduced current results of efforts has been developed and put into practice for the self-regulation of muscle tension. Training by using this biological feedback system causes a stable increase in the perception rate of proprioceptive stimulus in examinees (operates, sportsmen, neurological patients).

China has encountered many ups and downs in the field of education over the years. Although hampered by financial and personnel problems, impressive progress has been made in primary education since 1949, particularly in urban areas. The total education system is still weak, however, with a serious shortage of qualified teachers, school buildings, and other necessary facilities. Some of the problems involved are discussed. Current efforts aimed at increasing the level of compulsory education are outlined and observations are made on the status and plans relative to basic education, technical and vocational education, teacher training, resource requirements, enrollment trends, and so on.

The general objectives and planned direction of efforts in each of these areas is summarized.
Evaluated community fire safety interventions in the United States: a review of current literature.
Ta, Van M; Frattaroli, Shannon; Bergen, Gwendolyn; Gielen, Andrea Carlson
2006-06-01
The purpose of the study was to assess the state of fire prevention research, provide an updated synthesis of evaluated fire prevention programs, and discuss the role of fire fighters and data systems in prevention efforts. The review included all evaluations of U.S. based fire prevention interventions published between January 1998 and September 2004 and any earlier articles about U.S. fire prevention interventions not included in two prior review articles. We retrieved information from each identified study including evaluation findings, involvement of fire service personnel and use of existing data systems. We identified twelve articles: seven reported on smoke alarm interventions, three on multi-faceted programs, and two other programs. Five programs involved fire service personnel in the design, implementation, and/or evaluation, and three used existing data systems. Studies reviewed suggest that canvassing and smoke alarm installations are the most effective means of distributing alarms and increasing the functional status of distributed alarms. The functionality of smoke alarms, an issue noted in earlier reviews, remains a problem. Programs involving partnerships with fire departments have indicated success in preventing fires and deaths, improving smoke alarm ownership and functional status, and improving children's fire safety knowledge. Using existing data systems to target and to evaluate interventions was effective. In the years since prior reviews, some improvements in the rigor of evaluation designs have been made, but there is still a need for high quality evaluations that will inform fire injury prevention efforts.
Current status of nuclear engineering education

The 65 colleges and universities offering undergraduate degrees in nuclear engineering and the 15 schools offering strong nuclear engineering options are, in general, doing a good job to meet the current spectrum of job opportunities. But, nuclear engineering programs are not producing enough graduates to meet growing demands. They currently receive little aid and support from their customers --industry and government--in the form of scholarships, grants, faculty research support, student thesis and project support, or student summer jobs. There is not enough interaction between industry and universities. Most nuclear engineering programs are geared too closely to the technology of themore » present family of reactors and too little to the future breeder reactors and controlled thermonuclear reactors. In addition, nuclear engineering programs attract too few women and members of minority ethnic groups. Further study of the reasons for this fact is needed so that effective corrective action can be taken. Faculty in nuclear engineering programs should assume greater initiative to provide attractive and objective nuclear energy electives for technical and nontechnical students in other disciplines to improve their technical understanding of the safety and environmental issues involved. More aggressive and persistent efforts must be made by nuclear engineering schools to obtain industry support and involvement in their programs. (auth)« less
Molecular biology of pancreatic cancer.
Zavoral, Miroslav; Minarikova, Petra; Zavada, Filip; Salek, Cyril; Minarik, Marek
2011-06-28
In spite of continuous research efforts directed at early detection and treatment of pancreatic cancer, the outlook for patients affected by the disease remains dismal. With most cases still being diagnosed at advanced stages, no improvement in survival prognosis is achieved with current diagnostic imaging approaches. In the absence of a dominant precancerous condition, several risk factors have been identified including family history, chronic pancreatitis, smoking, diabetes mellitus, as well as certain genetic disorders such as hereditary pancreatitis, cystic fibrosis, familial atypical multiple mole melanoma, and Peutz-Jeghers and Lynch syndromes. Most pancreatic carcinomas, however, remain sporadic. Current progress in experimental molecular techniques has enabled detailed understanding of the molecular processes of pancreatic cancer development. According to the latest information, malignant pancreatic transformation involves multiple oncogenes and tumor-suppressor genes that are involved in a variety of signaling pathways. The most characteristic aberrations (somatic point mutations and allelic losses) affect oncogenes and tumor-suppressor genes within RAS, AKT and Wnt signaling, and have a key role in transcription and proliferation, as well as systems that regulate the cell cycle (SMAD/DPC, CDKN2A/p16) and apoptosis (TP53). Understanding of the underlying molecular mechanisms should promote development of new methodology for early diagnosis and facilitate improvement in current approaches for pancreatic cancer treatment.

An overview of the current status of the Thirty Meter Telescope (TMT) instrumentation program is presented. Conceptual designs for the three first light instruments (IRIS, WFOS and IRMS) are in progress, as well as feasibility studies of MIRES. Considerable effort is underway to understand the end-to-end performance of the complete telescopeadaptive optics-instrument system under realistic conditions on Mauna Kea. Highly efficient operation is being designed into the TMT system, based on a detailed investigation of the observation workflow to ensure very fast target acquisition and set up of all subsystems. Future TMT instruments will almost certainly involve contributions from institutions in many different locations in North America and partner nations. Coordinating and optimizing the design and construction of the instruments to ensure delivery of the best possible scientific capabilities is an interesting challenge. TMT welcomes involvement from all interested instrument teams.

The calculation of flux equations or current-voltage relationships in reaction kinetic models with a high number of states can be very cumbersome. Here, a recipe based on an arrow scheme is presented, which yields a straightforward access to the minimum form of the flux equations and the occupation probability of the involved states in cyclic and linear reaction schemes. This is extremely simple for cyclic schemes without branches. If branches are involved, the effort of setting up the equations is a little bit higher. However, also here a straightforward recipe making use of so-called reserve factors is provided for implementing the branches into the cyclic scheme, thus enabling also a simple treatment of such cases.

Adolescents involved in the juvenile justice system are prone to more traumatic events than other adolescents, leaving them in danger of developmental difficulties. Trauma exposure is predictive of poor outcomes including mental and physical health issues as well as criminal activity. Current treatment approaches either have a nominal effect on recidivism rates or increase the likelihood of future criminal offenses. This article explores adolescent brain development, the unique difficulties that juvenile justice youth face, and mindfulness meditation as an adjunctive treatment to system-based treatment. Mindfulness meditation may be a way to redress damage to the brain and facilitate healthy brain development, thus impacting prosocial behavior. Practice implications include integrating mindfulness meditation as an important part of rehabilitative efforts with juvenile justice youth.

Adolescents involved with foster care are five times more likely to receive a drug dependence diagnosis when compared to adolescents in the general population. Prior research has shown that substance use is often hidden from providers, negating any chance for treatment and almost guaranteeing poor post-foster care outcomes. There are virtually no studies that examine the willingness (and its determinants) to foster youth with substance abuse problems. The current study conducted a nationally-distributed survey of 752 currently licensed foster care parents that assessed willingness to foster youth overall and by type of drug used, and possible correlates of this decision (e.g., home factors, system factors, and individual foster parent factors such as ratings of perceived difficulty in fostering this population). Overall, willingness to foster a youth involved with alcohol and other drugs (AOD) was contingent upon the types of drugs used. The odds that a parent would foster an AOD-involved youth were significantly increased by being licensed as a treatment foster home, having fostered an AOD-involved youth in the past, having AOD-specific training and past agency-support when needed, and self-efficacy with respect to positive impact. Surprisingly, when religion played a large part in the decision to foster any child, the odds of willingness to foster an AOD-involved youth dropped significantly. These results suggest that a large proportion of AOD-involved youth who find themselves in the foster care system will not have foster families willing to parent them, thereby forcing placement into a variety of congregate care facilities (e.g., residential treatment facilities, group homes). Specific ways in which the system can address these issues to improve placement and permanency efforts is provided. PMID:25878368

Over the past 20 years, there has been a concerted effort to expand our understanding of the neural circuitry involved in the pathogenesis of psychiatric disorders. Distinct neuronal circuits and networks have been implicated in obsessive compulsive disorder (OCD) and major depressive disorder (MDD) involving feedback loops between the cortex, striatum, and thalamus. When neurosurgery is used as a therapeutic tool in severe OCD and MDD, the goal is to modulate specific targets or nodes within these networks in an effort to produce symptom relief. Currently, four lesioning neurosurgical procedures are utilized for treatment refractory OCD and MDD: cingulotomy, capsulotomy, subcaudate tractotomy, and limbic leucotomy. Deep brain stimulation (DBS) is a novel neurosurgical approach that has some distinct advantages over lesioning procedures. With DBS, the desired clinical effect can be achieved by reversible, high frequency stimulation in a nucleus or at a node in the circuit without the need to produce an irreversible lesion. Recent trials of deep brain stimulation in both OCD and MDD at several neuroanatomical targets have reported promising early results in highly refractory patients and with a good safety profile. Future definitive trials in MDD and OCD are envisaged. PMID:19727257

Background There is compelling evidence of a genetic foundation of patient-reported QOL. Given the rapid development of substantial scientific advances in this area of research, the current paper updates and extends reviews published in 2010. Objectives The objective is to provide an updated overview of the biological pathways, candidate genes and molecular markers involved in fatigue, pain, negative (depressed mood) and positive (well-being/happiness) emotional functioning, social functioning, and overall QOL. Methods We followed a purposeful search algorithm of existing literature to capture empirical papers investigating the relationship between biological pathways and molecular markers and the identified QOL domains. Results Multiple major pathways are involved in each QOL domain. The inflammatory pathway has the strongest evidence as a controlling mechanism underlying fatigue. Inflammation and neurotransmission are key processes involved in pain perception and the COMT gene is associated with multiple sorts of pain. The neurotransmitter and neuroplasticity theories have the strongest evidence for their relationship with depression. Oxytocin-related genes and genes involved in the serotonergic and dopaminergic pathways play a role in social functioning. Inflammatory pathways, via cytokines, also play an important role in overall QOL. Conclusions Whereas the current findings need future experiments and replication efforts, they will provide researchers supportive background information when embarking on studies relating candidate genes and/or molecular markers to QOL domains. The ultimate goal of this area of research is to enhance patients’ QOL. PMID:24604075

From Data to Knowledge through Concept-oriented Terminologies
Cimino, James J.
2000-01-01
Knowledge representation involves enumeration of conceptual symbols and arrangement of these symbols into some meaningful structure. Medical knowledge representation has traditionally focused more on the structure than the symbols. Several significant efforts are under way, at local, national, and international levels, to address the representation of the symbols though the creation of high-quality terminologies that are themselves knowledge based. This paper reviews these efforts, including the Medical Entities Dictionary (MED) in use at Columbia University and the New York Presbyterian Hospital. A decade's experience with the MED is summarized to serve as a proof-of-concept that knowledge-based terminologies can support the use of coded patient data for a variety of knowledge-based activities, including the improved understanding of patient data, the access of information sources relevant to specific patient care problems, the application of expert systems directly to the care of patients, and the discovery of new medical knowledge. The terminological knowledge in the MED has also been used successfully to support clinical application development and maintenance, including that of the MED itself. On the basis of this experience, current efforts to create standard knowledge-based terminologies appear to be justified. PMID:10833166

Knowledge representation involves enumeration of conceptual symbols and arrangement of these symbols into some meaningful structure. Medical knowledge representation has traditionally focused more on the structure than the symbols. Several significant efforts are under way, at local, national, and international levels, to address the representation of the symbols though the creation of high-quality terminologies that are themselves knowledge based. This paper reviews these efforts, including the Medical Entities Dictionary (MED) in use at Columbia University and the New York Presbyterian Hospital.

Borgquist, Signe; Hall, Per; Lipkus, Isaac; Garber, Judy E
2018-05-01
The dramatic increase in breast cancer incidence compels a paradigm shift in our preventive efforts. There are several barriers to overcome before prevention becomes an established part of breast cancer management. The objective of this review is to identify the clinical challenges for improved breast cancer prevention and discuss current knowledge on breast cancer risk assessment methods, risk communication, ethics, and interventional efforts with the aim of covering the aspects relevant for a breast cancer prevention trial. Herein, the following five areas are discussed: (i) Adequate tools for identification of women at high risk of breast cancer suggestively entitled Prevent! Online. (ii) Consensus on the definition of high risk, which is regarded as mandatory for all risk communication and potential prophylactic interventions. (iii) Risk perception and communication regarding risk information. (iv) Potential ethical concerns relevant for future breast cancer prevention programs. (v) Risk-reducing programs involving multileveled prevention depending on identified risk. Taken together, devoted efforts from both policy makers and health care providers are warranted to improve risk assessment and risk counseling in women at risk for breast cancer to optimize the prevention of breast cancer.

Variation-preserving normalization unveils blind spots in gene expression profiling
Roca, Carlos P.; Gomes, Susana I. L.; Amorim, Mónica J. B.; Scott-Fordsmand, Janeck J.
2017-01-01
RNA-Seq and gene expression microarrays provide comprehensive profiles of gene activity, but lack of reproducibility has hindered their application. A key challenge in the data analysis is the normalization of gene expression levels, which is currently performed following the implicit assumption that most genes are not differentially expressed. Here, we present a mathematical approach to normalization that makes no assumption of this sort. We have found that variation in gene expression is much larger than currently believed, and that it can be measured with available assays. Our results also explain, at least partially, the reproducibility problems encountered in transcriptomics studies. We expect that this improvement in detection will help efforts to realize the full potential of gene expression profiling, especially in analyses of cellular processes involving complex modulations of gene expression.

The development of resistance to insecticides by the vector of malaria and the increasingly faster appearance of resistance to antimalarial drugs by the parasite can dangerously hamper efforts to control and eradicate the disease. Alternative ways to treat this disease are urgently needed. Here we evaluate the in vitro effect of direct current (DC) capacitive coupling electrical stimulation on the biology and viability of Plasmodium falciparum. We designed a system that exposes infected erythrocytes to different capacitively coupled electric fields in order to evaluate their effect on P. falciparum. The effect on growth of the parasite, replication of DNA, mitochondrial membrane potential and level of reactive oxygen species after exposure to electric fields demonstrate that the parasite is biologically able to respond to stimuli from DC electric fields involving calcium signaling pathways.

Cikanek, H. A., III
1986-01-01
Past and future progress in the performance of control systems for large, liquid rocket engines typified such as current state-of-the-art, the Shuttle Main Engine (SSME), is discussed. Details of the first decade of efforts, which culminates in the F-1 and J-2 Saturn engines control systems, are traced, noting problem modes and improvements which were implemented to realize the SSME. Future control system designs, to accommodate the requirements of operation of engines for a heavy lift launch vehicle, an orbital transfer vehicle and the aerospace plane, are summarized. Generic design upgrades needed include an expanded range of fault detection, maintenance as-needed instead of as-scheduled, reduced human involvement in engine operations, and increased control of internal engine states. Current NASA technology development programs aimed at meeting the future control system requirements are described.

2015-01-01
Innovation and entrepreneurship in health care can help solve the current health care crisis by creating products and services that improve quality and convenience while reducing costs. To effectively drive innovation and entrepreneurship within the current health care delivery environment, academic institutions will need to provide education, promote networking across disciplines, align incentives, and adapt institutional cultures. This article provides a general review of entrepreneurship and commercialization from the perspective of academic radiology departments, drawing on information sources in several disciplines including radiology, medicine, law, and business. Our review will discuss the role of universities in supporting academic entrepreneurship, identify drivers of entrepreneurship, detail opportunities for academic radiologists, and outline key strategies that foster greater involvement of radiologists in entrepreneurial efforts and encourage leadership to embrace and support entrepreneurship.

Biologic therapies in the treatment of sarcoidosis.
Saketkoo, Lesley Ann; Baughman, Robert P
2016-08-01
Sarcoidosis is a disease of remarkable heterogeneity in organ manifestation, severity and natural history, characterized by the presence of non-caseating granulomas. The majority of cases are acute and self-limited or remit with short courses of glucocorticoids; however, a proportion progress to a life-threatening obliterative fibrotic type associated with significant disability related to pulmonary, cardiac, ocular or central nervous system involvement. Biologic agents have been demonstrated in the successful treatment of refractory organ-threatening sarcoidosis; and though sarcoidosis remains elusive in predictability of progression, strong evidence suggests an indisputably efficacious role for these agents in efforts to stave morbidity and mortality related to sarcoidosis. This paper provides a review of sarcoidosis mechanistic etiopathogenesis to highlight the hypothetical underpinnings of the utility and concerns of current biologic treatments in current use and the potential future applications of newer agents and those under development.

The Human Genome Project (HGP) is regarded by many as one of the major scientific achievements in recent science history, a large-scale endeavour that is changing the way in which biomedical research is done and expected, moreover, to yield considerable benefit for society. Thus, since the completion of the human genome sequencing effort, a debate has emerged over the question whether this effort merits to be awarded a Nobel Prize and if so, who should be the one(s) to receive it, as (according to current procedures) no more than three individuals can be selected. In this article, the HGP is taken as a case study to consider the ethical question to what extent it is still possible, in an era of big science, of large-scale consortia and global team work, to acknowledge and reward individual contributions to important breakthroughs in biomedical fields. Is it still viable to single out individuals for their decisive contributions in order to reward them in a fair and convincing way? Whereas the concept of the Nobel prize as such seems to reflect an archetypical view of scientists as solitary researchers who, at a certain point in their careers, make their one decisive discovery, this vision has proven to be problematic from the very outset. Already during the first decade of the Nobel era, Ivan Pavlov was denied the Prize several times before finally receiving it, on the basis of the argument that he had been active as a research manager (a designer and supervisor of research projects) rather than as a researcher himself. The question then is whether, in the case of the HGP, a research effort that involved the contributions of hundreds or even thousands of researchers worldwide, it is still possible to “individualise” the Prize? The “HGP Nobel Prize problem” is regarded as an exemplary issue in current research ethics, highlighting a number of quandaries and trends involved in contemporary life science research practices more broadly.

The war on drugs in sport: a perspective from the front-line.
Mendoza, John
2002-07-01
Recent international developments have served to solidify the international approach to doping in sport. The development of the World Anti-Doping Agency (WADA) has resulted in new, coordinated efforts to address this important sport issue. An array of new efforts and initiatives has been initiated by the new agency. The Sydney and Salt Lake City Olympics were characterized by intensive efforts to minimize doping. The antidoping environment is evolving rapidly, and several profoundly important developments will take place in the immediate future. To outline the challenges, opportunities, and changing circumstances of the current antidoping environment so that sport medicine practitioners might understand the context in which a variety of new initiatives and approaches will develop. At the same time, to ensure that practitioners understand the importance of appropriately developed and delivered antidoping policies, programs, and procedures, and the need for their harmonization. To ensure that sport medicine practitioners appreciate the need for a comprehensive approach to doping control, i.e., programs that include much more than drug testing. A review of relevant policy documents derived from a variety of sport and antidoping organizations; selected references drawn from MEDLINE; and materials prepared by colleagues drawn from the international antidoping community. The increased global effort to address doping is welcome. It will require that several critical issues be addressed that will test the resolve of all involved.
Dopamine, Effort-Based Choice, and Behavioral Economics: Basic and Translational Research
Salamone, John D.; Correa, Merce; Yang, Jen-Hau; Rotolo, Renee; Presby, Rose
2018-01-01
Operant behavior is not only regulated by factors related to the quality or quantity of reinforcement, but also by the work requirements inherent in performing instrumental actions. Moreover, organisms often make effort-related decisions involving economic choices such as cost/benefit analyses. Effort-based decision making is studied using behavioral procedures that offer choices between high-effort options leading to relatively preferred reinforcers vs. low effort/low reward choices. Several neural systems, including the mesolimbic dopamine (DA) system and other brain circuits, are involved in regulating effort-related aspects of motivation. Considerable evidence indicates that mesolimbic DA transmission exerts a bi-directional control over exertion of effort on instrumental behavior tasks. Interference with DA transmission produces a low-effort bias in animals tested on effort-based choice tasks, while increasing DA transmission with drugs such as DA transport blockers tends to enhance selection of high-effort options. The results from these pharmacology studies are corroborated by the findings from recent articles using optogenetic, chemogenetic and physiological techniques. In addition to providing important information about the neural regulation of motivated behavior, effort-based choice tasks are useful for developing animal models of some of the motivational symptoms that are seen in people with various psychiatric and neurological disorders (e.g., depression, schizophrenia, Parkinson’s disease). Studies of effort-based decision making may ultimately contribute to the development of novel drug treatments for motivational dysfunction. PMID:29628879

In the past years, new developments have occurred both in the understanding of the biology of Waldenstrom Macroglobulinemia (WM) and in therapeutic options for WM. WM is a B-cell disorder characterized primarily by bone marrow infiltration with lymphoplasmacytic cells, along with demonstration of an IgM monoclonal gammopathy. Despite advances in therapy, WM remains incurable, with 5–6 years median overall survival of patients in symptomatic WM. Therapy is postponed for asymptomatic patients, and progressive anemia is the most common indication for initiation of treatment. The main therapeutic options include alkylating agents, nucleoside analogues, and rituximab. Studies involving combination chemotherapy are ongoing, and preliminary results are encouraging. No specific agent or regimen has been shown to be superior to another for treatment of WM. As such, novel therapeutic agents are needed for the treatment of WM. In ongoing efforts, we and others have sought to exploit advances made in the understanding of the biology of WM so as to better target therapeutics for this malignancy. These efforts have led to the development of several novel agents including the proteasome inhibitor bortezomib, and several Akt/mTor inhibitors, perifosine and Rad001, and immunomodulatory agents such as thalidomide and lenalidomide. Studies with monoclonal antibodies are ongoing and promising including the use of alemtuzumab, SGN-70, and the APRIL/BLYS blocking protein TACI-Ig atacicept. Other agents currently being tested in clinical trials include the PKC inhibitor enzastaurin, the natural product resveratrol, as well as the statin simvastatin. This report provides an update of the current preclinical studies and clinical efforts for the development of novel agents in the treatment of WM. PMID:18555588

Acute stress has been shown to enhance learning and memory ability, predominantly through the action of corticosteroid stress hormones. However, the valuable targets for promoting learning and memory induced by acute stress and the underlying molecular mechanisms remain unclear. Acid-sensing ion channels (ASICs) play an important role in central neuronal systems and involves in depression, synaptic plasticity and learning and memory. In the current study, we used a combination of electrophysiological and behavioral approaches in an effort to explore the effects of acute stress on ASICs. We found that corticosterone (CORT) induced by acute stress caused a potentiation of ASICs current via glucocorticoid receptors (GRs) not mineralocorticoid receptors (MRs). Meanwhile, CORT did not produce an increase of ASICs current by pretreated with GF109203X, an antagonist of protein kinase C (PKC), whereas CORT did result in a markedly enhancement of ASICs current by bryostatin 1, an agonist of PKC, suggesting that potentiation of ASICs function may be depended on PKC activating. More importantly, an antagonist of ASICs, amiloride (10 μM) reduced the performance of learning and memory induced by acute stress, which is further suggesting that ASICs as the key components involves in cognitive processes induced by acute stress. These results indicate that acute stress causes the enhancement of ASICs function by activating PKC signaling pathway, which leads to potentiated learning and memory. Copyright © 2018 Elsevier Inc.

Forman, R. G.; Shivakumar, V.; Newman, J. C., Jr.
1994-01-01
The NASA/FLAGRO (NASGRO) computer program was developed for fracture control analysis of space hardware and is currently the standard computer code in NASA, the U.S. Air Force, and the European Agency (ESA) for this purpose. The significant attributes of the NASGRO program are the numerous crack case solutions, the large materials file, the improved growth rate equation based on crack closure theory, and the user-friendly promptive input features. In support of the National Aging Aircraft Research Program (NAARP); NASGRO is being further developed to provide advanced state-of-the-art capability for damage tolerance and crack growth analysis of aircraft structural problems, including mechanical systems and engines. The project currently involves a cooperative development effort by NASA, FAA, and ESA. The primary tasks underway are the incorporation of advanced methodology for crack growth rate retardation resulting from spectrum loading and improved analysis for determining crack instability. Also, the current weight function solutions in NASGRO or nonlinear stress gradient problems are being extended to more crack cases, and the 2-d boundary integral routine for stress analysis and stress-intensity factor solutions is being extended to 3-d problems. Lastly, effort is underway to enhance the program to operate on personal computers and work stations in a Windows environment. Because of the increasing and already wide usage of NASGRO, the code offers an excellent mechanism for technology transfer for new fatigue and fracture mechanics capabilities developed within NAARP.

For over two decades, the Goddard Astrophysics Education Team has been an integrated part of NASA Goddard’s Astrophysics Science Division. As part of NASA’s largest astrophysics organization, our team is in a unique position to collaborate with the division’s scientists, engineers, and technical personnel - our subject matter experts (SMEs) - in a variety of capacities. We often seek input from our SMEs to help implement our education programs - to ensure our programs’ scientific accuracy, to help us employ cutting-edge topics, and to promote authentic science processes. At the same time, we act as education experts for our SMEs to help them implement their ideas. We see this as a true partnership, with many opportunities for SME participation. Our current STEM Activation programs, Afterschool Universe and NASA Family Science Night, were created with strong involvement from division scientists, and our latest sessions on galaxies were developed in collaboration with an active researcher. In addition to our own programming, we have been tasked with providing NASA astrophysics content and expertise to the Goddard Office of Education, the Heliophysics Education Consortium (and their cross-division efforts), and the NASA Science Mission Directorate STEM Activation Community. This talk will provide an overview of our team’s current efforts and the ways in which we partner with our division’s SMEs.
Ceramics in Restorative and Prosthetic DENTISTRY1

Kelly, J. Robert
1997-08-01
This review is intended to provide the ceramic engineer with information about the history and current use of ceramics in dentistry, contemporary research topics, and potential research agenda. Background material includes intra-oral design considerations, descriptions of ceramic dental components, and the origin, composition, and microstructure of current dental ceramics. Attention is paid to efforts involving net-shape processing, machining as a forming method, and the analysis of clinical failure. A rationale is presented for the further development of all-ceramic restorative systems. Current research topics receiving attention include microstructure/processing/property relationships, clinical failure mechanisms and in vitro testing, wear damage and wear testing, surface treatments, and microstructural modifications. The status of the field is critically reviewed with an eye toward future work. Significant improvements seem possible in the clinical use of ceramics based on engineering solutions derived from the study of clinically failed restorations, on the incorporation of higher levels of "biomimicry" in new systems, and on the synergistic developments in dental cements and adhesive dentin bonding.

Objectives. We compared patient-reported receipt of smoking cessation counseling from US dentists and physicians. Methods. We analyzed the 2010 to 2011 Tobacco Use Supplement of the Current Population Survey to assess receipt of smoking cessation advice and assistance by a current smoker from a dentist or physician in the past 12 months. Results. Current adult smokers were significantly less likely to be advised to quit smoking during a visit to a dentist (31.2%) than to a physician (64.8%). Among physician patients who were advised to quit, 52.7% received at least 1 form of assistance beyond the simple advice to quit; 24.5% of dental patients received such assistance (P < .05). Approximately 9.4 million smokers who visited a dentist in 2010 to 2011 did not receive any cessation counseling. Conclusions. Our results indicate a need for intensified efforts to increase dentist involvement in cessation counseling. System-level changes, coupled with regular training, may enhance self-efficacy of dentists in engaging patients in tobacco cessation counseling. PMID:24922172
Upgrades to the NSTX HHFW antenna

2014-02-01
The High Harmonic Fast Wave (HHFW) antenna for the National Spherical Torus Experiment (NSTX) at PPPL will be upgraded as part of the NSTX upgrade project. Higher magnetic fields and plasma current result in disruption forces on the current straps that can be up to four times the original design values. The current straps on the HHFW antenna are presently fed by coaxial feedthroughs with rigid center conductors. The additional forces on the current straps require a compliant section in the center conductor in order to minimize the forces on the feedthrough. The design of this compliant section has been an integrated effort involving electrostatic calculations in parallel with mechanical and thermal analyses, in order to arrive at a design that is optimized for mechanical, thermal and electrical considerations. The voltage standoff obtained from this design will be verified when a prototype antenna is evaluated on our RF test stand. This paper describes the design of the compliant section of the center conductor, mechanical, thermal and electrostatic calculations, and plans for full implementation of the upgrade on NSTX.
The do-not-resuscitate order in teaching hospitals.
Evans, A L; Brody, B A
1985-04-19
We studied the use of do-not-resuscitate (DNR) orders at three teaching hospitals that did not have official protocols for such orders to see whether their use meets the goals (decision making before a crisis and promoting patient autonomy) that have been identified for such orders. We found that 20% of all patients had or were being considered for DNR orders, that the patient and/or family was usually involved (83%) in the decision not to resuscitate, but rarely involved (25%) in decisions to resuscitate, or in cases of no decision, that a wide range of care was provided to patients with a DNR status, and that partial resuscitative efforts would be employed in some cases. Our main conclusion in light of our findings is that DNR orders are currently not fulfilling their major goals. We offer six proposals for improving future DNR protocols.

Recent research (e.g., Hutter, Crisp, Humphreys, Waters, & Moffit; Siebler) has confirmed that combining novel social categories involves two stages (e.g., Hampton; Hastie, Schroeder, & Weber). Furthermore, it is also evident that following stage 1 (constituent additivity), the second stage in these models involves cognitively effortful complex reasoning. However, while current theory and research has addressed how category conjunctions are initially represented to some degree, it is not clear precisely where we first combine or bind existing social constituent categories. For example, how and where do we compose and temporarily store a coherent representation of an individual who shares membership of "female" and "blacksmith" categories? In this article, we consider how the revised multi-component model of working memory (Baddeley) can assist in resolving the representational limitations in the extant two-stage theoretical models. This is a new approach to understanding how novel conjunctions form new bound "composite" representations.
The Department of Veterans Affairs' role in Federal Emergency Management.
Kizer, K W; Cushing, T S; Nishimi, R Y
2000-09-01
The Veterans Health Administration (VHA) has been increasingly called on to provide disaster relief health care personnel and other emergency assistance since the role of the Department of Veterans Affairs in emergency management was expanded by the Federal Response Plan in 1992. This article briefly reviews the VHA's emergency management functions currently specified by the Federal Response Plan and its present activities in procuring and maintaining antidotes, antibiotics, and other pharmaceutical stockpiles to be used in response to terrorist incidents involving weapons of mass destruction. In view of VHA's national scope and extensive assets, its administration by the government, and its critical role in health professional training, there are several additional ways that VHA could economically augment the federal government's efforts to better support and prepare local jurisdictions for disasters or incidents involving weapons of mass destruction, if the required authorization and funding were provided.

In college and university residence halls, resident assistants (RAs) are expected to serve as first-aid providers to students who may have alcohol, other drug, mental health, and academic problems. Despite this responsibility, evidence-based, first-aid programs have not been developed and tested for the RA workforce. The current study examined effects of an investigational first-aid program designed specifically for RAs. The online Peer Hero Training program is a novel approach to RA training in its use of interactive video dramatizations of incidents involving substance-using or distressed residents. A 9-month randomized trial conducted on eight US campuses compared RAs who participated in the Peer Hero Training program to RAs who received training-as-usual. Participation in the Peer Hero Training program significantly increased RA first-aid efforts for residential students who may have had alcohol, other drug, mental health, or academic problems 6 months after baseline. Compared with those in the training-as-usual condition, RAs in the Peer Hero Training program made more than 10 times as many first-aid efforts for possible alcohol problems, almost 14 times the number of first-aid efforts for possible drug use, almost 3 times the number of first-aid efforts for possible mental health problems, and 3 times the number of first-aid efforts for academic problems. There was no evidence that measured RA attitudes mediated the effects of the intervention. Results of this preliminary evaluation trial suggest that online training using interactive video dramatizations is a viable approach to strengthening RAs' ability to provide alcohol, other drugs, and mental health first-aid to undergraduates.
Aerospace Meteorology Lessons Learned Relative to Aerospace Vehicle Design and Operations
NASA Technical Reports Server (NTRS)
Vaughan, William W.; Anderson, B. Jeffrey
2004-01-01
Aerospace Meteorology came into being in the 1950s as the development of rockets for military and civilian usage grew in the United States. The term was coined to identify those involved in the development of natural environment models, design/operational requirements, and environment measurement systems to support the needs of aerospace vehicles, both launch vehicles and spacecraft. It encompassed the atmospheric environment of the Earth, including Earth orbit environments. Several groups within the United States were active in this area, including the Department of Defense, National Aeronautics and Space Administration, and a few of the aerospace industry groups. Some aerospace meteorology efforts were similar to those being undertaken relative to aviation interests. As part of the aerospace meteorology activities a number of lessons learned resulted that produced follow on efforts which benefited from these experiences, thus leading to the rather efficient and technologically current descriptions of terrestrial environment design requirements, prelaunch monitoring systems, and forecast capabilities available to support the development and operations of aerospace vehicles.
Pick your poison: what's new in poison control for the preschooler.
Glenn, Lauren
2015-01-01
Accidental childhood poisonings are a major public health concern despite many efforts to alleviate this problem. While the rate of pediatric fatalities due to poisonings have decreased over the last two decades, poison control centers around the US have collectively fielded over one million calls with regard to toxic exposures in the preschool age group. According to the American Association of Poison Control Centers nearly half of all human exposures reported last year involved children under six. By focusing poison prevention efforts on the preschooler, we can attempt to decrease morbidity and mortality in the most vulnerable age group affected. Although the subject is still prevalent, current discussion on this topic is limited. Newer literature discusses past initiatives such as child resistant packaging and sticker deterrent programs and addresses their efficacy. This article revisits older mechanisms of prevention as well as the science behind the human motivation to change one's own practice and behavior. Copyright © 2015 Elsevier Inc. All rights reserved.

Tobacco companies are increasingly turning to trade and investment agreements to challenge measures aimed at reducing tobacco use. This study examines their efforts to influence the Trans-Pacific Partnership (TPP), a major trade and investment agreement which may eventually cover 40% of the world's population; focusing on how these efforts might enhance the industry's power to challenge the introduction of plain packaging. Specifically, the paper discusses the implications for public health regulation of Philip Morris International's interest in using the TPP to: shape the bureaucratic structures and decision-making processes of business regulation at the national level; introduce a higher standard of protection for trademarks than is currently provided under the Agreement on Trade Related Aspects of Intellectual Property Rights; and expand the coverage of Investor-State Dispute Settlement which empowers corporations to litigate directly against governments where they are deemed to be in breach of investment agreements. The large number of countries involved in the TPP underlines its risk to the development of tobacco regulation globally.
THE CHALLENGING ROLE OF A READING COACH, A CAUTIONARY TALE
AL OTAIBA, STEPHANIE; HOSP, JOHN L.; SMARTT, SUSAN; DOLE, JANICE A.
2011-01-01
The purpose of this case study is to describe the challenges one coach faced during the initial implementation of a coaching initiative involving 33 teachers in an urban, high-poverty elementary school. Reading coaches are increasingly expected to play a key role in the professional development efforts to improve reading instruction in order to improve reading achievement for struggling readers. Data sources included initial reading scores for kindergarten and first-graders, pretest and posttest scores of teachers’ knowledge, a teacher survey, focus group interviews, project documents, and field notes. Data were analyzed using a mixed methods approach. Findings revealed several challenges that have important implications for research and practice: that teachers encountered new information about teaching early reading that conflicted with their current knowledge, this new information conflicted with their core reading program, teachers had differing perceptions of the role of the reading coach that affected their feelings about the project, and reform efforts are time-intensive.

Environmental monitoring requires regular observations regarding the status of the landscape- The concept behind most monitoring efforts using satellite data involve deriving normalized difference vegetation index (NDVI) values or accumulating the NDVI over a specified time period. These efforts attempt to estimate the continuous growth of green biomass by using continuous additions of NDVI as a surrogate measure. To build upon this concept, this study proposes three refinements; 1) use an objective definition of the current growing season to adjust the time window during which the NDVI is accumulated, 2) accumulate only the NDVI values which are affected by green vegetation, and 3) base monitoring units upon land cover type. These refinements improve the sensitivity of detecting interannual vegetation variability, reduce the need for extensive and detailed knowledge of ground conditions and crop calendars, provide a framework in which several types of monitoring can take place over diverse land cover types, and provide an objective time frame during which monitoring takes place.

The University of Texas at El Paso (UTEP) is involved in several initiatives to improve science education within the El Paso area public schools. These include outreach efforts into the K- 12 classrooms; training programs for in-service teachers; and the introduction of a strong science core curricula within the College of Education. The Pan American Center for Earth and Environmental Studies (PACES), a NASA-funded University Research Center, will leverage off the goals of these existing initiatives to provide curriculum support materials at all levels. We will use currently available Mission to Planet Earth (MTPE) materials as well as new materials developed specifically for this region, in an effort to introduce the Earth System Science perspective into these programs. In addition, we are developing curriculum support materials and classes within the Geology and Computer Departments, to provide education in the area of remote sensing and GIS applications at the undergraduate and graduate levels.

Tobacco companies are increasingly turning to trade and investment agreements to challenge measures aimed at reducing tobacco use. This study examines their efforts to influence the Trans-Pacific Partnership (TPP), a major trade and investment agreement which may eventually cover 40% of the world's population; focusing on how these efforts might enhance the industry's power to challenge the introduction of plain packaging. Specifically, the paper discusses the implications for public health regulation of Philip Morris International's interest in using the TPP to: shape the bureaucratic structures and decision-making processes of business regulation at the national level; introduce a higher standard of protection for trademarks than is currently provided under the Agreement on Trade Related Aspects of Intellectual Property Rights; and expand the coverage of Investor-State Dispute Settlement which empowers corporations to litigate directly against governments where they are deemed to be in breach of investment agreements. The large number of countries involved in the TPP underlines its risk to the development of tobacco regulation globally. PMID:23788606

The NASA Lewis Research Center is actively involved in the development of expert system technology to assist users in applying parallel processing to computational fluid and structural dynamic analysis. The goal of this effort is to eliminate the necessity for the physical scientist to become a computer scientist in order to effectively use the computer as a research tool. Programming and operating software utilities have previously been developed to solve systems of ordinary nonlinear differential equations on parallel scalar processors. Current efforts are aimed at extending these capabilities to systems of partial differential equations, that describe the complex behavior of fluids and structures within aerospace propulsion systems. This paper presents some important considerations in the redesign, in particular, the need for algorithms and software utilities that can automatically identify data flow patterns in the application program and partition and allocate calculations to the parallel processors. A library-oriented multiprocessing concept for integrating the hardware and software functions is described.

The primary goal of the effort that resulted in this report was to update the earlier report issued by the NCRP on this subject (NCRP, 1977). In so doing, the Council has identified additional consumer products that can be sources of ionizing radiation, and has deleted coverage of some products that are either no longer available or whose use has essentially been discontinued. For each source category, a major effort has been made to provide data on the number of products currently in use, the rate at which such usage is changing, and the range of typical dose equivalents beingmore » received from that source by the general public. To the extent possible, an attempt has been made to provide information to assist in making decisions on whether a given application might better be replaced by some other method of accomplishing the same task without involving radiation exposure to the population. 162 refs., 2 figs., 23 tabs.« less

Istanbul, with a population of around 13 million people, is located between Europe and Asia and is the biggest city in Turkey. Metropolitan Istanbul produces about 14,000 tons of solid waste per day. The aim of this study was to assess the situation of municipal solid-waste (MSW) management in Istanbul. This was achieved by reviewing the quantity and composition of waste produced in Istanbul. Current requirements and challenges in relation to the optimization of Istanbul's MSW collection and management system are also discussed, and several suggestions for solving the problems identified are presented. The recovery of solid waste from themore » landfills, as well as the amounts of landfill-generated biogas and electricity, were evaluated. In recent years, MSW management in Istanbul has improved because of strong governance and institutional involvement. However, efforts directed toward applied research are still required to enable better waste management. These efforts will greatly support decision making on the part of municipal authorities. There remains a great need to reduce the volume of MSW in Istanbul.« less

An effort is made to ascertain which combinations of technical demands and crew coordination should be incorporated in training scenarios in order to maximize the effectiveness of training for crew members. Such high-fidelity simulation, which has come to be known as 'line-oriented flight training' or LOFT, involves the practice of both technical and crew coordination skills in a realistic setting, in conjunction with periodic reviews of performance via videotaped feedback. Attention is given to the integration of appropriate information, the measurement of objective task demands, the character of information from LOFT students, and the leeway allowed LOFT instructors.

2018-01-01
During the last years, chemistry was involved in the worldwide effort toward environmental problems leading to the birth of green chemistry. In this context, green analytical tools were developed as modern Supercritical Fluid Chromatography in the field of separative techniques. This chromatographic technique knew resurgence a few years ago, thanks to its high efficiency, fastness and robustness of new generation equipment. These advantages and its easy hyphenation to MS fulfill the requirements of bioanalysis regarding separation capacity and high throughput. In the present paper, the technical aspects focused on bioanalysis specifications will be detailed followed by a critical review of bioanalytical supercritical fluid chromatography methods published in the literature.

The utility of quantitative molecular diagnostics for patient management depends on the ability to relate patient results to prior results or to absolute values in clinical practice guidelines. To do this, those results need to be comparable across time and methods, either by producing the same value across methods and test versions or by using reliable and stable conversions. Universally available standards and reference materials specific to quantitative molecular technologies are critical to this process but are few in number. This review describes recent history in the establishment of international standards for nucleic acid test development, organizations involved in current efforts, and future issues and initiatives.

Reformulation of food products to reduce salt content has been a central strategy for achieving population level salt reduction. In this paper, we reflect on current reformulation strategies and consider how consumer behavior determines the ultimate success of these strategies. We consider the merits of adopting a 'health by stealth', silent approach to reformulation compared to implementing a communications strategy which draws on labeling initiatives in tandem with reformulation efforts. We end this paper by calling for a multi-actor approach which utilizes co-design, participatory tools to facilitate the involvement of all stakeholders, including, and especially, consumers, in making decisions around how best to achieve population-level salt reduction.
Clinical Application of Growth Factors and Cytokines in Wound Healing
Barrientos, Stephan; Brem, Harold; Stojadinovic, Olivera; Tomic-Canic, Marjana
2016-01-01
Wound healing is a complex and dynamic biological process that involves the coordinated efforts of multiple cell types and is executed and regulated by numerous growth factors and cytokines. There has been a drive in the past two decades to study the therapeutic effects of various growth factors in the clinical management of non-healing wounds (e.g. pressure ulcers, chronic venous ulcers, diabetic foot ulcers). For this review, we conducted a nonline search of Medline and Pub Medical and critically analyzed the literature regarding the role of growth factors and cytokines in the management of these wounds. We focused on currently approved therapies, emerging therapies and future research possibilities. In this review we discuss four growth factors and cytokines currently being used on and off label for the healing of wounds. These include: granulocyte-macrophage colony stimulating factor (GM-CSF), platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF). While the clinical results of using growth factors and cytokines are encouraging, many studies involved a small sample size and are disparate in measured endpoints. Therefore, further research is required to provide definitive evidence of efficacy. PMID:24942811
Separate and overlapping brain areas encode subjective value during delay and effort discounting.
Massar, Stijn A A; Libedinsky, Camilo; Weiyan, Chee; Huettel, Scott A; Chee, Michael W L

Making decisions about rewards that involve delay or effort requires the integration of value and cost information. The brain areas recruited in this integration have been well characterized for delay discounting. However only a few studies have investigated how effort costs are integrated into value signals to eventually determine choice. In contrast to previous studies that have evaluated fMRI signals related to physical effort, we used a task that focused on cognitive effort. Participants discounted the value of delayed and effortful rewards. The value of cognitively effortful rewards was represented in the anterior portion of the inferior frontal gyrus and dorsolateral prefrontal cortex. Additionally, the value of the chosen option was encoded in the anterior cingulate cortex, caudate, and cerebellum. While most brain regions showed no significant dissociation between effort discounting and delay discounting, the ACC was significantly more activated in effort compared to delay discounting tasks. Finally, overlapping regions within the right orbitofrontal cortex and lateral temporal and parietal cortices encoded the value of the chosen option during both delay and effort discounting tasks. These results indicate that encoding of rewards discounted by cognitive effort and delay involves partially dissociable brain areas, but a common representation of chosen value is present in the orbitofrontal, temporal and parietal cortices.

Research has confirmed a positive link between patient involvement in decision-making and improvements in health outcomes. The objective of this study was to examine the roles of psychological empowerment and health literacy on the elderly's willingness to engage in treatment decisions. A self-administered questionnaire was completed by a randomly selected sample of Swiss adults aged 65-80 years old (N = 826). Multivariate logistic regression was applied to determine the contribution of health literacy, psychological empowerment, and trust in physician on participants' preference to be active, collaborative or passive in decision-making. Most of the survey respondents preferred some participation in dealing with health related decisions (collaborative: 51%, and active: 35.6%). More than two-thirds of the sample was satisfied with their current involvement in medical decision-making (72.7%). Roughly one-fifth (18.8%) wished to attain a more active engagement than currently experienced, and the remainder of the sample preferred the opposite (8.5%). Due to higher reported levels of psychological empowerment and health literacy, Swiss-German seniors significantly preferred and assumed higher participation in medical decisions than Swiss-Italians. Psychological empowerment correlated with older adults' preferred and perceived involvement in medical decision-making. However, health literacy only predicted actual involvement in the last treatment decision that had to be made, differentiating only the active from the passive involvement group. Additionally, this research showed that health literacy mediated the relationship between psychological empowerment and the actual involvement in the last treatment decision that had to be made by the participant. Trust in physician and age appeared to be barriers to involvement, whereas education served as a facilitator. As older adults' health literacy plays a role in individuals' willingness to attain an active role in health care decision-making, public health efforts should aim at developing programs and appropriate information that facilitate this process, especially for individuals with moderate or lower levels of health literacy. The current investigation showed that adequate health literacy levels are essential (but not sufficient) in order to reach higher rates of participation in the healthcare context. This research complements past evidence by adding knowledge on the psychosocial antecedents, and their combined effects on patients' involvement in healthcare.
Prediction of enjoyment in school physical education.
Gråstén, Arto; Jaakkola, Timo; Liukkonen, Jarmo; Watt, Anthony; Yli-Piipari, Sami
2012-01-01
The specific aim of this study was to examine whether motivational climate, perceived physical competence, and exercise motivation predict enjoyment in school physical education within the same sample of adolescents across three years of secondary school. A sample of 639 students (girls = 296, boys = 343) aged between 13- to 15-years at the commencement of the study completed the Intrinsic Motivation Climate in Physical Education Questionnaire, Physical Self-Perception Profile, Physical Education Motivation Scale, and Physical Education Enjoyment Scale. Results derived from path analyses indicated that task-involving motivational climate predicted enjoyment in physical education via perceived physical competence and intrinsic motivation in both girls and boys. In particular, these results supported previous findings of Vallerand et. al (1997) with the self-determination theory and the achievement goal theory. Ego-involving climate was not a significant predictor either in girls or boys. The current results provide continuing support for the investigation of Vallerand's model in the physical education setting, and highlight that motivational climate is an area that requires further evaluation as a contributing factor in the improvement of physical education teaching. A better understanding of the role of motivational climate may assist efforts to promote children's and adolescents' perceived physical competence, intrinsic motivation, and enjoyment in the school physical education setting. Key pointsThe findings of the current study support existing suggestions of Vallerand's (1997) model in which social factors mediated by a psychological mediator, and exercise motivation are related to positive consequences in the PE context.Task-involving motivational climate predicted PE enjoyment via perceived physical competence and intrinsic motivation with both girls and boys. Task-involving motivational climate in PE lessons at Grade 7 had a strong association with PE enjoyment via perceived physical competence and intrinsic motivation at Grade 9 for both girls and boys.Ego-involving climate did not fit either the data for the girls or boys, as PE lessons based on ego-involving motivational climate did not significantly influence on the level of PE enjoyment.The results of the current study and previous practical findings support task-involving teaching methods to promote adolescent's PE enjoyment through secondary school years. School PE could be most effective if based on task-involving motivational climate, in which the main objective is increasing students' perceived physical competence, intrinsic motivation, and enjoyment.

Current Grid operation and future role of the Grid
NASA Astrophysics Data System (ADS)
Smirnova, O.
2012-12-01
Grid-like technologies and approaches became an integral part of HEP experiments. Some other scientific communities also use similar technologies for data-intensive computations. The distinct feature of Grid computing is the ability to federate heterogeneous resources of different ownership into a seamless infrastructure, accessible via a single log-on. Like other infrastructures of similar nature, Grid functioning requires not only technologically sound basis, but also reliable operation procedures, monitoring and accounting. The two aspects, technological and operational, are closely related: weaker is the technology, more burden is on operations, and other way around. As of today, Grid technologies are still evolving: at CERN alone, every LHC experiment uses an own Grid-like system. This inevitably creates a heavy load on operations. Infrastructure maintenance, monitoring and incident response are done on several levels, from local system administrators to large international organisations, involving massive human effort worldwide. The necessity to commit substantial resources is one of the obstacles faced by smaller research communities when moving computing to the Grid. Moreover, most current Grid solutions were developed under significant influence of HEP use cases, and thus need additional effort to adapt them to other applications. Reluctance of many non-HEP researchers to use Grid negatively affects the outlook for national Grid organisations, which strive to provide multi-science services. We started from the situation where Grid organisations were fused with HEP laboratories and national HEP research programmes; we hope to move towards the world where Grid will ultimately reach the status of generic public computing and storage service provider and permanent national and international Grid infrastructures will be established. How far will we be able to advance along this path, depends on us. If no standardisation and convergence efforts will take place, Grid will become limited to HEP; if however the current multitude of Grid-like systems will converge to a generic, modular and extensible solution, Grid will become true to its name.
Man, mind, and machine: the past and future of virtual reality simulation in neurologic surgery.
Robison, R Aaron; Liu, Charles Y; Apuzzo, Michael L J
2011-11-01
To review virtual reality in neurosurgery, including the history of simulation and virtual reality and some of the current implementations; to examine some of the technical challenges involved; and to propose a potential paradigm for the development of virtual reality in neurosurgery going forward. A search was made on PubMed using key words surgical simulation, virtual reality, haptics, collision detection, and volumetric modeling to assess the current status of virtual reality in neurosurgery. Based on previous results, investigators extrapolated the possible integration of existing efforts and potential future directions. Simulation has a rich history in surgical training, and there are numerous currently existing applications and systems that involve virtual reality. All existing applications are limited to specific task-oriented functions and typically sacrifice visual realism for real-time interactivity or vice versa, owing to numerous technical challenges in rendering a virtual space in real time, including graphic and tissue modeling, collision detection, and direction of the haptic interface. With ongoing technical advancements in computer hardware and graphic and physical rendering, incremental or modular development of a fully immersive, multipurpose virtual reality neurosurgical simulator is feasible. The use of virtual reality in neurosurgery is predicted to change the nature of neurosurgical education, and to play an increased role in surgical rehearsal and the continuing education and credentialing of surgical practitioners.

The U.S. High Frequency Radar Network (HFRNet) has been in operation for over ten years with representation from 31 organizations spanning academic institutions, state and local government agencies, and private organizations. HFRNet currently holds a collection from over 130 radar installations totaling over 10 million records of surface ocean velocity measurements. HFRNet is a primary example of inter-agency and inter-institutional partnerships for improving oceanographic research and operations. HF radar derived surface currents have been used in several societal applications including coastal search and rescue, oil spill response, water quality monitoring and marine navigation. Central to the operational success of the large scale network is an efficient data management, storage, access, and delivery system. The networking of surface current mapping systems is characterized by a tiered structure that extends from the individual field installations to local regional operations maintaining multiple sites and on to centralized locations aggregating data from all regions. The data system development effort focuses on building robust data communications from remote field locations (sites) for ingestion into the data system via data on-ramps (Portals or Site Aggregators) to centralized data repositories (Nodes). Centralized surface current data enables the aggregation of national surface current grids and allows for ingestion into displays, management tools, and models. The Coastal Observing Research and Development Center has been involved in international relationships and research in the Philippines, Palau, and Vietnam. CORDC extends this IT architecture of surface current mapping data systems leveraging existing developments and furthering standardization of data services for seamless integration of higher level applications. Collaborations include the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA), The Coral Reef Research Foundation (CRRF), and the Center for Oceanography/Vietnamese Administration of Seas and Islands (CFO/VASI). These collaborations and data sharing improve our abilities to respond to regional, national, and global environmental and management issues.
Parental spanking of 1-year-old children and subsequent child protective services involvement.
Lee, Shawna J; Grogan-Kaylor, Andrew; Berger, Lawrence M
2014-05-01
The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], p<.01). When compared to non-spanked children, there was a 33% greater probability of subsequent CPS involvement for children who were spanked at age 1. Given the undesirable consequences of spanking children and a lack of empirical evidence to suggest positive effects of physical punishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life. Copyright © 2014 Elsevier Ltd. All rights reserved.
A forensic science perspective on the role of images in crime investigation and reconstruction.
Milliet, Quentin; Delémont, Olivier; Margot, Pierre
2014-12-01
This article presents a global vision of images in forensic science. The proliferation of perspectives on the use of images throughout criminal investigations and the increasing demand for research on this topic seem to demand a forensic science-based analysis. In this study, the definitions of and concepts related to material traces are revisited and applied to images, and a structured approach is used to persuade the scientific community to extend and improve the use of images as traces in criminal investigations. Current research efforts focus on technical issues and evidence assessment. This article provides a sound foundation for rationalising and explaining the processes involved in the production of clues from trace images. For example, the mechanisms through which these visual traces become clues of presence or action are described. An extensive literature review of forensic image analysis emphasises the existing guidelines and knowledge available for answering investigative questions (who, what, where, when and how). However, complementary developments are still necessary to demystify many aspects of image analysis in forensic science, including how to review and select images or use them to reconstruct an event or assist intelligence efforts. The hypothetico-deductive reasoning pathway used to discover unknown elements of an event or crime can also help scientists understand the underlying processes involved in their decision making. An analysis of a single image in an investigative or probative context is used to demonstrate the highly informative potential of images as traces and/or clues. Research efforts should be directed toward formalising the extraction and combination of clues from images. An appropriate methodology is key to expanding the use of images in forensic science.

The crucial contribution of veterinarians to conservation biology.
Reading, Richard P; Kenny, David E; Fitzgerald, Kevin T
2013-11-01
Conservation biology is a relatively new (began in the 1980s), value-based discipline predicated on the belief that biological diversity-from genes to populations to species to communities to ecosystems-is good and extinction is bad. Conservation biology grew from the recognition that the Earth has entered its sixth great extinction event, one that differs from previous great extinctions in that a single species-Homo sapiens-has caused this biodiversity crisis. A diverse, interacting set of variables drive current extinctions. As such, to succeed, conservation efforts usually require broad-based, interdisciplinary approaches. Conservationists increasingly recognize the importance of contributions by veterinary science, among many other disciplines, to collaborative efforts aimed at stemming the loss of biodiversity. We argue that, to improve success rates, many wildlife conservation programs must incorporate veterinarians as part of an interdisciplinary team to assess and address problems. Ideally, veterinarians who participate in conservation would receive specialized training and be willing to work as partners as part of a larger team of experts who effectively integrate their work rather than work independently (i.e., work as interdisciplinary, as opposed to multidisciplinary, teams, respectively). In our opinion, the most successful and productive projects involve interdisciplinary teams involving both biological and nonbiological specialists. Some researchers hold multiple degrees in biology and veterinary medicine or the biological and social sciences. These experts can often offer unique insight. We see at least 3 major areas in which veterinarians can immediately offer great assistance to conservation efforts: (1) participation in wildlife capture and immobilization, (2) leadership or assistance in addressing wildlife health issues, and (3) leadership or assistance in addressing wildlife disease issues, including using wildlife as sentinels to identify new and emerging diseases or epidemics of old diseases. We cover each of these main topics in detail. © 2013 Published by Elsevier Inc.
International Collaborations in Large Geophysical Experiments: A Win-Win Situation
NASA Astrophysics Data System (ADS)
Keller, G. R.
2007-12-01
It has been my privilege to be involved in a significant number of large international cooperative geophysical experiments. These logistically challenging efforts all took place in developing or under-developed countries and were co-driven at least to some extent by scientists in the host country. A team of scientists from developed countries were involved in each case but were not always the leaders of the effort. The host countries were all supportive and played roles ranging from simply facilitating the effort to providing most of the funding. Some lessons learned from these efforts were the following: 1) permissions for large efforts must come from very high levels in the host government; 2) the host scientists should never be overlooked or underestimated; 3) involving students from both the host country and developed countries produces big educational and cultural dividends for all involved (it is a life experience for the visitors and a chance to widen perspectives and even acquire advanced degrees for the students from the host countries); 4) providing funds for scientists and students from the host country to visit their international partners to participate in the data processing and analysis and to attend scientific meetings is extremely important; 5) return trips to the host country to collaborate on data processing and analysis and to consolidate partnerships are also important; 6) the partnership with the host country should be viewed as a long term commitment to scientific cooperation and education that benefits all involved. Our experiences have encountered only a few roadblocks and have been ultimately universally positive. Lifelong relationships have been forged, students have been educated and enriched, and excellent scientific results have been produced.

LANDFIRE, also known as the Landscape Fire and Resource Management Planning Tools Program, is a vegetation, fire, and fuel characteristic data creation program managed by both the U.S. Department of Agriculture Forest Service and the U.S. Department of the Interior with involvement from The Nature Conservancy. LANDFIRE represents the first and only complete, nationally consistent collection of over 20 geo-spatial layers (e.g., vegetation type and structure, fuels, fire regimes), databases, and ecological models that can be used across multiple disciplines to support cross-boundary planning, management, and operations across all lands of the United States and insular areas. Since 2004, LANDFIRE has produced comprehensive, consistent, and scientifically based suites of mapped products and associated databases for the United States and affiliated territories. These products depict the nation's major ecosystems and wildlife habitats. Over a decade has passed since the development of the first LANDFIRE base map, and an overhaul of the data products, i.e., a "Remap", is needed to maintain their functionality and relevance. To prepare for Remap production LANDFIRE has invested in a prototyping phase that focused on exploring various input data sources and new modeling and mapping techniques. While still grounded in a solid base consisting of Landsat imagery and high-quality field observations, the prototyping efforts explored different image compositing techniques, the integration of lidar data, modeling approaches as well as other factors that will inform Remap production. Several of these various research efforts are highlighted here and are currently being integrated into an end-to-end data processing flow that will drive the Remap production. The current Remap prototype effort has focused on several study areas throughout CONUS, with additional studies anticipated for Alaska, Hawaii and the territories. The LANDFIRE Remap effort is expected to take three to four years, with production commencing in northwestern CONUS.

Attentional effort relates to the allocation of limited-capacity attentional resources to meet current task demands and involves the activation of top-down attentional systems in the brain. Pupillometry is a sensitive measure of this intensity aspect of top-down attentional control. Studies relate pupillary changes in response to cognitive processing to activity in the locus coeruleus (LC), which is the main hub of the brain's noradrenergic system and it is thought to modulate the operations of the brain's attentional systems. In the present study, participants performed a visual divided attention task known as multiple object tracking (MOT) while their pupil sizes were recorded by use of an infrared eye tracker and then were tested again with the same paradigm while brain activity was recorded using fMRI. We hypothesized that the individual pupil dilations, as an index of individual differences in mental effort, as originally proposed by Kahneman (1973), would be a better predictor of LC activity than the number of tracked objects during MOT. The current results support our hypothesis, since we observed pupil-related activity in the LC. Moreover, the changes in the pupil correlated with activity in the superior colliculus and the right thalamus, as well as cortical activity in the dorsal attention network, which previous studies have shown to be strongly activated during visual tracking of multiple targets. Follow-up pupillometric analyses of the MOT task in the same individuals also revealed that individual differences to cognitive load can be remarkably stable over a lag of several years. To our knowledge this is the first study using pupil dilations as an index of attentional effort in the MOT task and also relating these to functional changes in the brain that directly implicate the LC-NE system in the allocation of processing resources.

Quality of life (QoL) and life satisfaction (LS) are important outcome factors in chronic inflammatory conditions such as Behçet's disease (BD). The aim of this study was to investigate QoL and LS in patients with BD and determine the relationship with disease activity. Forty-one patients with BD and 40 control subjects were involved in the study. Demographic properties were obtained. Disease activity was assessed by Turkish version of BD Current Activity Form (BDCAF) in BD patients. QoL and psychological well-being were assessed by Nottingham Health Profile (NHP) and Life Satisfaction Index (LSI), respectively, in both patients and control groups. The related disease activity measures of QoL and LS were determined. Twenty-two male and 19 female BD patients with a mean age of 33.3+/-9.3 years and 20 male and 20 female control subjects with a mean age of 33.3+/-4.1 years were involved. According to BDCAF, no patient had central nervous system involvement. Thirty-four patients had headache, 33 patients had fatigue, 30 patients had articular involvement, 29 had mucocutaneous lesions, 27 had gastrointestinal involvement, 21 patients had ocular involvement, and 7 patients had vascular involvement. The scores of all dimensions of NHP were significantly higher and the mean score of LSI was significantly lower in BD patients than in control subjects (p<0.001). Correlation analysis indicated that the scores of fatigue, joint involvement, and oral ulcers were the most related factors for physical domains of NHP, whereas joint involvement and genital ulcers were the most related activity measures for psychosocial subscales of NHP. LS was found to be most related with the scores of patient's and physician's impression of disease activity and joint involvement. In conclusion, patients with BD have impaired QoL and disturbed psychological well-being. Current management strategies focusing on fatigue, arthralgia, mucocutaneous lesions, and efforts to measure psychosocial aspects and symptoms of the patients by their point of view will help to improve QoL and raise the LS in patients suffering from BD.

Starch is the main polymer in which carbon and energy are stored in land plants, algae and some cyanobacteria. It plays a crucial role in the physiology of these organisms and also represents an important polymer for humans, in terms of both diet and nonfood industry uses. Recent efforts have elucidated most of the steps involved in the synthesis of starch. However, the process that initiates the synthesis of the starch granule remains unclear. Here, we outline the similarities between the synthesis of starch and the synthesis of glycogen, the other widespread and abundant glucose-based polymer in living cells. We place special emphasis on the mechanisms of initiation of the glycogen granule and current knowledge concerning the initiation of the starch granule. We also discuss recent discoveries regarding the function of starch synthases in the priming of the starch granule and possible interactions with other elements of the starch synthesis machinery.

Many couples present fertility problems at their reproductive age, and although in the last years, the efficiency of assisted reproduction techniques has increased, these are still far from being 100% effective. A key issue in this field is the proper assessment of germ cells, embryos and endometrium quality, in order to determine the actual likelihood to succeed. Currently available analysis is mainly based on morphological features of oocytes, sperm and embryos and although these strategies have improved the results, there is an urgent need of new diagnostic and therapeutic tools. The emergence of the - OMICS technologies (epigenomics, genomics, transcriptomics, proteomics and metabolomics) permitted the improvement on the knowledge in this field, by providing with a huge amount of information regarding the biological processes involved in reproductive success, thereby getting a broader view of complex biological systems with a relatively low cost and effort.

In the past 10 years, Fermilab has been executing an intensive R&D program on accelerator magnets based on Nb 3Sn superconductor technology. This R&D effort includes dipole and quadrupole models for different programs, such as LARP and 11 T dipoles for the LHC high-luminosity upgrade. Before the Nb 3Sn R&D program, Fermilab was involved in the production of the low-beta quadrupole magnets for LHC based on the NbTi superconductor. Additionally, during the 2003-2005 campaign to optimize the operation of the Tevatron, a large number of Tevatron magnets were re-measured. As a result of this field analysis, a systematic study ofmore » the persistent current decay and snapback effect in these magnets was performed. This paper summarizes the result of this study and presents a comparison between Nb 3Sn and NbTi dipoles and quadrupoles.« less
Potential high efficiency solar cells: Applications from space photovoltaic research

NASA involvement in photovoltaic energy conversion research development and applications spans over two decades of continuous progress. Solar cell research and development programs conducted by the Lewis Research Center's Photovoltaic Branch have produced a sound technology base not only for the space program, but for terrestrial applications as well. The fundamental goals which have guided the NASA photovoltaic program are to improve the efficiency and lifetime, and to reduce the mass and cost of photovoltaic energy conversion devices and arrays for use in space. The major efforts in the current Lewis program are on high efficiency, single crystal GaAs planar and concentrator cells, radiation hard InP cells, and superlattice solar cells. A brief historical perspective of accomplishments in high efficiency space solar cells will be given, and current work in all of the above categories will be described. The applicability of space cell research and technology to terrestrial photovoltaics will be discussed.
Medicare Part D Beneficiaries' Plan Switching Decisions and Information Processing.
Han, Jayoung; Urmie, Julie
2017-03-01
Medicare Part D beneficiaries tend not to switch plans despite the government's efforts to engage beneficiaries in the plan switching process. Understanding current and alternative plan features is a necessary step to make informed plan switching decisions. This study explored beneficiaries' plan switching using a mixed-methods approach, with a focus on the concept of information processing. We found large variation in beneficiary comprehension of plan information among both switchers and nonswitchers. Knowledge about alternative plans was especially poor, with only about half of switchers and 2 in 10 nonswitchers being well informed about plans other than their current plan. We also found that helpers had a prominent role in plan decision making-nearly twice as many switchers as nonswitchers worked with helpers for their plan selection. Our study suggests that easier access to helpers as well as helpers' extensive involvement in the decision-making process promote informed plan switching decisions.

Tanks of radioactively contaminated kerosene/tributyl phosphate (TBP) disposed of at West Valley in 1969, when the plant was being utilized to reprocess commercial nuclear fuel, were determined to be leaking. Contaminated kerosene/TBP was initially detected in November 1983 when samples taken from US Geological Survey monitor wells tested positively for both radioactive and organic constituents. An extensive monitoring, sampling, and analysis program, which involved the installation of approx. 100 monitor points, core bores, and scavenger wells, has been in effect since November 1983 when the migrating kerosene/TBP was initially discovered. Sample analysis has served to provide data on the radionuclidemore » concentration as the kerosene/TBP migrates through the soil. Recent acquisition of a portable gas chromatograph is expected to yield even more definitive information on migration rates. Removal of organics from the scavenger wells will continue while more permanent control measures are finalized. The current efforts will involve the installation of a support structure, erection of a light-weight reusable weather shelter, excavation and potential removal of the tanks and contents, as well as packaging and/or otherwise stabilizing of the resulting waste. The significance of this project is that it will provide a data base for future work in former radioactive disposal sites. A discussion of the monitoring, sampling, and analysis is provided in conjunction with the stabilization efforts.« less

Replacing hydrogen with deuterium as a means of altering ADME properties of drug molecules has recently enjoyed a renaissance, such that at least two deuterated chemical entities are currently in clinical development. Although most research in this area aims to increase the metabolic stability, and hence half-life of the active species, experience has shown that prediction of the in vivo behaviour of deuterated molecules is difficult and depends on multiple factors including the complexity of the metabolic scheme, the enzymes involved and hence the mechanism of the rate-determining step in the biotransformation. In an effort to elucidate some of these factors we examined the metabolic behaviour of two molecules from the Sanofi portfolio in a range of in vitro and in vivo systems. Although some key metabolic reactions of the acetylcholine release stimulator HP184 4 were slowed in vitro and in vivo when deuterium was present at the sites of metabolism, this did not translate to an increase in overall metabolic stability. By contrast, the tryptase inhibitor AVE5638 13 was much more metabolically stable in vitro in its deuterated form than when unlabelled. These results indicate that it could be of value to concentrate efforts in this area to molecules which are metabolised by a major pathway that involves enzymes of the amine oxidase family or other low-capacity enzyme families.

Essential elements of personalized medicine.
Burke, Wylie; Brown Trinidad, Susan; Press, Nancy A
2014-02-01
Genomic information has been promoted as the basis for "personalized" health care. We considered the benefits provided by genomic testing in context of the concept of personalized medicine. We evaluated current and potential uses of genomic testing in health care, using prostate cancer as an example, and considered their implications for individualizing or otherwise improving health care. Personalized medicine is most accurately seen as a comprehensive effort to tailor health care to the individual, spanning multiple dimensions. While genomic tests will offer many potential opportunities to improve the delivery of care, including the potential for genomic research to offer opportunities to improve prostate cancer screening and treatment, such advances do not in themselves constitute a paradigm shift in the delivery of health care. Rather, personalized medicine is based on a partnership between clinician and patient that utilizes shared decision making to determine the best health care options among the available choices, weighing the patient's personal values and preferences together with clinical findings. This approach is particularly important for difficult clinical decisions involving uncertainty and trade-offs, such as those involved in prostate cancer screening and management. The delivery of personalized medicine also requires adequate health care access and assurance that basic health needs have been met. Substantial research investment will be needed to identify how genomic tests can contribute to this effort. © 2014 Published by Elsevier Inc.

Despite initiatives supporting young adults with intellectual and developmental disabilities (IDD) to engage in post-secondary education and integrated employment, those with more intensive support needs are not as easily involved in these post-school experiences. In an effort to learn from positive examples, we examined parent involvement in meaningful post-school experiences by eight young adults with IDD and pervasive support needs. Secondary analysis of data from a prior interview study yielded this smaller sample of eight young adults with meaningful post-school experiences. Their parents were actively involved as fierce advocates and creative problem solvers. The active involvement of parents included: a) attitudinal facilitators, b) advocacy efforts and perceptions, and c) strategic actions. Implications for future research and practice are described.

Theories of autobiographical memory distinguish between involuntary and voluntary retrieval as a consequence of conscious intention (i.e., wanting to remember). Another distinction can be made between direct and generative retrieval, which reflects the effort involved (i.e., trying to remember). However, it is unclear how intention and effort interacts. For example, involuntary memories and directly retrieved memories have been used interchangeably in the literature to refer to the same phenomenon of effortless, non-strategic retrieval. More recent theoretical advances suggest that they are separate types of retrieval, one unintentional (involuntary), another intentional and effortless (direct voluntary retrieval), and a third intentional and effortful (generative voluntary retrieval). Whether this also entails differing phenomenological characteristics, such as vividness, rehearsal, or emotional valence, has not been previously investigated. In the current study, participants reported memories in an experimental paradigm designed to elicit voluntary and involuntary memories and rated them on a number of characteristics. If intention affects the retrieval process, then we should expect differences between the characteristics of involuntary and directly retrieved memories. The results imply that retrieval intention seems to differentiate how a memory appears in a person's mind. Furthermore, we argue that these differences in part could result from differences in encoding and consolidation. © 2015 The British Psychological Society.

The growth of academic international medicine (AIM) as a distinct field of expertise resulted in increasing participation by individual and institutional actors from both high-income and low-and-middle-income countries. This trend resulted in the gradual evolution of international medical programs (IMPs). With the growing number of students, residents, and educators who gravitate toward nontraditional forms of academic contribution, the need arose for a system of formalized metrics and quantitative assessment of AIM- and IMP-related efforts. Within this emerging paradigm, an institution's “return on investment” from faculty involvement in AIM and participation in IMPs can be measured by establishing equivalency between international work and various established academic activities that lead to greater institutional visibility and reputational impact. The goal of this consensus statement is to provide a basic framework for quantitative assessment and standardized metrics of professional effort attributable to active faculty engagement in AIM and participation in IMPs. Implicit to the current work is the understanding that the proposed system should be flexible and adaptable to the dynamically evolving landscape of AIM – an increasingly important subset of general academic medical activities.

The Streetlight Effect in Type 1 Diabetes
Battaglia, Manuela
2015-01-01
In the nearly 100 years since the discovery of therapeutic insulin, significant research efforts have been directed at finding the underlying cause of type 1 diabetes (T1D) and developing a “cure” for the disease. While progress has clearly been made toward each of these goals, neither vision has been fulfilled. With increasing pressure from both public and private funders of diabetes research, growing impatience of those with T1D at the lack of practical discoveries, increased competition for research funds, uncertainties on the reproducibility of published scientific data, and questions regarding the value of animal models, the current research environment has become extraordinarily difficult to traverse from the perspective of investigators. As a result, there is an increasing pressure toward performance of what might be considered “safe” research, where the aim is to affirm existing dogmas rather than to pioneer efforts involving unconventional thought. Psychologists refer to this practice as “observational bias” while cartoonists label the process the “streetlight effect.” In this Perspective, we consider notions in T1D research that should be subject to bold question and provide additional concepts, many somewhat orphan to research efforts, whose investigation could lead to a means for truly identifying the cause of and a cure for T1D.

Unwillingness to expend more effort to pursue high value rewards has been associated with motivational anhedonia in schizophrenia (SCZ) and abnormal dopamine activity in the nucleus accumbens (NAcc). The authors hypothesized that dysfunction of the NAcc and the associated forebrain regions are involved in the impaired effort expenditure decision-making of SCZ. A 2 (reward magnitude: low vs. high) × 3 (probability: 20% vs. 50% vs. 80%) event-related fMRI design in the effort-expenditure for reward task (EEfRT) was used to examine the neural response of 23 SCZ patients and 23 demographically matched control participants when the participants made effort expenditure decisions to pursue uncertain rewards. SCZ patients were significantly less likely to expend high level of effort in the medium (50%) and high (80%) probability conditions than healthy controls. The neural response in the NAcc, the posterior cingulate gyrus and the left medial frontal gyrus in SCZ patients were weaker than healthy controls and did not linearly increase with an increase in reward magnitude and probability. Moreover, NAcc activity was positively correlated with the willingness to expend high-level effort and concrete consummatory pleasure experience. NAcc and posterior cingulate dysfunctions in SCZ patients may be involved in their impaired effort expenditure decision-making. (PsycINFO Database Record (c) 2016 APA, all rights reserved).
Diagnostic overview of the illegal trade in primates and law enforcement in Peru.

Peru has one of the richest primate faunas of any country. The illegal trade in wild primates is one of the largest threats to this fauna in Peru. We characterize the illegal trade in primates through empirical and ethnographic data. We collected data from traffic routes and centers throughout Peru and evaluate current efforts to combat this traffic. Based on our findings from 2,070 instances of wildlife crime involving 6,872 primates, we estimate the domestic trade in primates for pets and bushmeat in Peru in the hundreds of thousands per year, with the larger bodied Atelidae facing the highest direct consequences. We found that government authorities lack sufficient staff, capacity, resources, infrastructure, and protocols to efficiently combat illegal trade in primates. Also, the complicated legal framework and lack of cooperation and antagonism with the public further limit these efforts. Wildlife authorities in Peru are able to confiscate only a fraction of primates traded and mostly intervene in cases of private pet owners rather than traffickers. We estimate that the current rate of illegal trade in primates is comparable to levels of trade prior to the 1973 ban on primates' exportation. The combination of direct observations on primate trade and ethnographic data allows a comprehensive look at primate trade in Peru. We call upon decision makers and international funders to channel their efforts toward "on the ground" actions such as increasing the ability of the authorities to act, giving them "in action" training in law enforcement and establishing strict control measures against corruption.

A Serviced-based Approach to Connect Seismological Infrastructures: Current Efforts at the IRIS DMC

Ahern, Tim; Trabant, Chad
2014-05-01
As part of the COOPEUS initiative to build infrastructure that connects European and US research infrastructures, IRIS has advocated for the development of Federated services based upon internationally recognized standards using web services. By deploying International Federation of Digital Seismograph Networks (FDSN) endorsed web services at multiple data centers in the US and Europe, we have shown that integration within seismological domain can be realized. By deploying identical methods to invoke the web services at multiple centers this approach can significantly ease the methods through which a scientist can access seismic data (time series, metadata, and earthquake catalogs) from distributed federated centers. IRIS has developed an IRIS federator that helps a user identify where seismic data from global seismic networks can be accessed. The web services based federator can build the appropriate URLs and return them to client software running on the scientists own computer. These URLs are then used to directly pull data from the distributed center in a very peer-based fashion. IRIS is also involved in deploying web services across horizontal domains. As part of the US National Science Foundation's (NSF) EarthCube effort, an IRIS led EarthCube Building Block's project is underway. When completed this project will aid in the discovery, access, and usability of data across multiple geoscienece domains. This presentation will summarize current IRIS efforts in building vertical integration infrastructure within seismology working closely with 5 centers in Europe and 2 centers in the US, as well as how we are taking first steps toward horizontal integration of data from 14 different domains in the US, in Europe, and around the world.

To estimate the potential supply of organ donors and to measure the efficiency of organ procurement efforts in the United States. A geographic database has been developed consisting of multiple cause of death and sociodemographic data compiled by the National Center for Health Statistics. All deaths are evaluated as to their potential for organ donation. Two classes of potential donors are identified: class 1 estimates are restricted to causes of death involving significant head trauma only, and class 2 estimates include class 1 estimates as well as deaths in which brain death was less probable. Over 23,000 people are currently awaiting a kidney, heart, liver, heart-lung, pancreas, or lung transplantation. Donor supply is inadequate, and the number of donors remained unchanged at approximately 4000 annually for 1986 through 1989, with a modest 9.1% increase in 1990. Between 6900 and 10,700 potential donors are available annually (eg, 28.5 to 43.7 per million population). Depending on the class of donor considered, organ procurement efforts are between 37% and 59% efficient. Efficiency greatly varies by state and organ procurement organization. Many more organ donors are available than are being accessed through existing organ procurement efforts. Realistically, it may be possible to increase by 80% the number of donors available in the United States (up to 7300 annually). It is conceivable, although unlikely, that the supply of donor organs could achieve a level to meet demand.

The University of Nebraska at Omaha has been a state leader in helping Nebraska teachers embrace earth systems science education, with a special emphasis in online coursework. UNO was one of the initial members in the Earth Systems Science Education Alliance (ESSEA) and has offered three different ESSEA courses, with a total of 167 students having taken ESSEA courses at UNO for graduate credit. UNO is currently involved in expanding its earth system science courses, modules, and educational research. We are also integrating these courses into several degree programs, including a Masters of Science in Education, a new Middle School Endorsement, a Certificate in Urban Education, and the Graduate Program for the Department of Geography/Geology. UNO is beginning to examine teacher content learning and science reasoning within its coursework. Feedback surveys from earlier ESSEA offerings already indicate a strongly positive perception of the courses by the teachers enrolled in the coursework. Project impact has been documented in teacher projects, quotes, and lessons associated with the coursework activities. We will describe the UNO earth system science efforts (emphasizing ESSEA coursework), and describe past efforts and teacher perceptions, as well as new strategies being undertaken to more closely examine content learning and science reasoning impact with course participants. We will also describe online course modules being developed within the UNO online course efforts, including one on the global amphibian crisis, and also the impact of urbanization on a local native prairie environment.

Public awareness of space weather and its adverse effects on critical infrastructure systems, services, and technologies (e.g., the electric grid, telecommunications, and satellites) has grown through recent media coverage and scientific research. However, federal interest and involvement in space weather dates back to the decades between World War I and World War II when the National Bureau of Standards led efforts to observe, forecast, and provide warnings of space weather events that could interfere with high-frequency radio transmissions. The efforts to observe and predict space weather continued through the 1960s during the rise of the Cold War and into the present with U.S. government efforts to prepare the nation for space weather events. This paper provides a brief overview of the history of federal involvement in space weather forecasting from World War II, through the Apollo Program, and into the present.

A symposium at the 40th anniversary of the Environmental Mutagen Society, held from October 24–28, 2009 in St. Louis, MO, surveyed the current status and future directions of genetic toxicology. This article summarizes the presentations and provides a perspective on the future. An abbreviated history is presented, highlighting the current standard battery of genotoxicity assays and persistent challenges. Application of computational toxicology to safety testing within a regulatory setting is discussed as a means for reducing the need for animal testing and human clinical trials, and current approaches and applications of in silico genotoxicity screening approaches across the pharmaceutical industry were surveyed and are reported here. The expanded use of toxicogenomics to illuminate mechanisms and bridge genotoxicity and carcinogenicity, and new public efforts to use high-throughput screening technologies to address lack of toxicity evaluation for the backlog of thousands of industrial chemicals in the environment are detailed. The Tox21 project involves coordinated efforts of four U.S. Government regulatory/research entities to use new and innovative assays to characterize key steps in toxicity pathways, including genotoxic and nongenotoxic mechanisms for carcinogenesis. Progress to date, highlighting preliminary test results from the National Toxicology Program is summarized. Finally, an overview is presented of ToxCast™, a related research program of the U.S. Environmental Protection Agency, using a broad array of high throughput and high content technologies for toxicity profiling of environmental chemicals, and computational toxicology modeling. Progress and challenges, including the pressing need to incorporate metabolic activation capability, are summarized. PMID:21538556
Current State of Nanomedicines in the Treatment of Topical Infectious Disorders.

Topical infections, involving a number of diseases such as impetigo, eczema, pustular acne, psoriasis and infected seborrheic dermatitis are one among the many challenges to health which stand out for their profound impact on human species. The treatment of topical infections has always been a difficult proposition because of the lack of efficacy of existing anti-infectives, longer period of treatment and yet incomplete recovery. The increasing emergence of antibiotic resistant bacterial strains like Staphylococcus aureus, Methicillin-Resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa undermine the need of development of new delivery systems to enhance the therapeutic efficacy of existing topical anti-infectives. The application of nanotechnology to medicine, or nanomedicine, is rapidly becoming a major driving force behind ongoing changes in the anti-infective field because of its interaction at the sub-atomic level with the skin tissue. The latter, in the current scenario, points towards vesicular carriers like liposomes, lipidic nanoparticles and silver nanoparticles etc. as the most promising drug delivery solutions for topical infection disorders. These have exhibited immense significance owing to their uniqueness to facilitate the interactions at interfaces with the barrier membranes. The present review summarizes the emerging efforts in combating topical infections particularly using nanomedicine based delivery systems as new tools to tackle the current challenges in treating infectious diseases.

Although integration involves a process of mutual accommodation, the role of majority groups is often downplayed to passive tolerance, leaving immigrants with the sole responsibility for active integration. However, we show that common group identity can actively involve majority members in this process across five studies. Study 1 showed that common identity positively predicted support of integration efforts; Studies 2 and 3 extended these findings, showing that it also predicted real behavior such as monetary donations and volunteering. A decrease in modern racism mediated the relations across these studies, and Studies 4 and 5 further demonstrated that it indeed mediated these effects over and above acculturation expectations and color-blindness, which somewhat compromised integration efforts. Moreover, the last two studies also demonstrated that common, but not dual, groups motivated integration efforts. Common identity appears crucial for securing majorities' altruistic efforts to integrate immigrants and, thus, for achieving functional multiculturalism. © 2015 by the Society for Personality and Social Psychology, Inc.

Objective: The current study examines the relation between peer descriptive norms for alcohol involvement and alcohol-dependence symptomatology and whether this relation differs as a function of sexual self-concept ambiguity (SSA). This study also examines the associations among peer descriptive norms for alcohol involvement, alcohol-dependence symptomatology, and lifetime HIV risk-taking behavior and how these relations are influenced by SSA. Method: Women between ages 18 and 30 years (N = 351; M = 20.96, SD = 2.92) completed an online survey assessing sexual self-concept, peer descriptive norms, alcohol-dependence symptomatology, and HIV risk-taking behaviors. Structural equation modeling was used to test hypotheses of interest. Results: There was a significant latent variable interaction between SSA and descriptive norms for peer alcohol use. There was a stronger positive relationship between peer descriptive norms for alcohol and alcohol-dependence symptomatology when SSA was higher compared with when SSA was lower. Both latent variables exhibited positive simple associations with alcohol-dependence symptoms. Peer descriptive norms for alcohol involvement directly and indirectly influenced HIV risk-taking behaviors, and the indirect influence was conditional based on SSA. Conclusions: The current findings illustrate complex, nuanced associations between perceived norms, identity-related self-concepts, and risky health behaviors from various domains. Future intervention efforts may be warranted to address both problem alcohol use and HIV-risk engagement among individuals with greater sexual self-concept ambiguity. PMID:25343661

Asia's changing role in global climate change.
Siddiqi, Toufiq A
2008-10-01
Asia's role in global climate change has evolved significantly from the time when the Kyoto Protocol was being negotiated. Emissions of carbon dioxide, the principal greenhouse gas, from energy use in Asian countries now exceed those from the European Union or North America. Three of the top five emitters-China, India, and Japan, are Asian countries. Any meaningful global effort to address global climate change requires the active cooperation of these and other large Asian countries, if it is to succeed. Issues of equity between countries, within countries, and between generations, need to be tackled. Some quantitative current and historic data to illustrate the difficulties involved are provided, and one approach to making progress is suggested.

Renal cell carcinoma (RCC) represents a deadly disease with rising mortality despite intensive therapeutic efforts. It comprises several subtypes in terms of distinct histopathological features and different clinical presentations. Long non-coding RNAs (lncRNAs) are non-protein-coding transcripts in the genome which vary in expression levels and length and perform diverse functions. They are involved in the inititation, evolution and progression of primary cancer, as well as in the development and spread of metastases. Recently, several lncRNAs were described in RCC. This review emphasises the rising importance of lncRNAs in RCC. Moreover, it provides an outlook on their therapeutic potential in the future. PMID:27092491

The biological redundancies in molecular networks of complex diseases limit the efficacy of many single drug therapies. Combination therapeutics, as a common therapeutic method, involve pharmacological intervention using several drugs that interact with multiple targets in the molecular networks of diseases and may achieve better efficacy and/or less toxicity than monotherapy in practice. The development of combination therapeutics is complicated by several critical issues, including identifying multiple targets, targeting strategies and the drug combination. This review summarizes the current achievements in combination therapeutics, with a particular emphasis on the efforts to develop combination therapeutics for complex diseases. © 2016 The Authors.

Applying a Consumer Behavior Lens to Salt Reduction Initiatives
Potvin Kent, Monique; Raats, Monique M.; McConnon, Áine; Wall, Patrick; Dubois, Lise
2017-01-01
Reformulation of food products to reduce salt content has been a central strategy for achieving population level salt reduction. In this paper, we reflect on current reformulation strategies and consider how consumer behavior determines the ultimate success of these strategies. We consider the merits of adopting a ‘health by stealth’, silent approach to reformulation compared to implementing a communications strategy which draws on labeling initiatives in tandem with reformulation efforts. We end this paper by calling for a multi-actor approach which utilizes co-design, participatory tools to facilitate the involvement of all stakeholders, including, and especially, consumers, in making decisions around how best to achieve population-level salt reduction.

This paper describes the problems involved in uplink of data from control centers on the ground to spacecraft, and explores the solutions to those problems, past. present. and future. The evolution of this process, from simple commanding to transfer of large volumes of data and commands is traced. The need for reliable end-to-end protocols for commanding and file transfer is demonstrated, and the shortcomings of both existing telecommand protocols and commercial products to meet this need are discussed. Recent developments in commercial protocols that may be adaptable to the mentioned operations environment are surveyed, and current efforts to develop a suite of protocols for reliable transfer in this environment are presented.

The translation of basic behavioral science discoveries into practical strategies represents a promising approach to developing more effective preventive interventions to improve health. Since translational research inevitably involves making use of diverse perspectives from multiple disciplines, it is best conducted as a transdisciplinary enterprise. In this paper, we discuss current strategies used by NIH to support transdisciplinary translational behavioral (TDTB) research, summarize successful efforts, and highlight challenges encountered in conducting such work (ranging from conceptual to organizational to methodological). Using examples from NIH-funded projects we illustrate the potential benefits of, and barriers to, pursuing this type of research and discuss next steps and potential future directions for NIH-supported TDTB research.
[Various forms of current sex taboo-ism from the gynecologist's point of view].
Kvíz, D
1977-05-01
Antisexual primary Christian traditions, which consist of, as a rule, a mixture of suppression, silencing, intimidation, and threat, still have sufficiently extensive sociopsychological consequences to disrupt the psychosexual equilibrium of an individual. This has been seen through the great number of single women who, upon requesting artificial abortion, desire to keep their situation a secret, particularly from the parents. A similar attitude of "taboo" has been observed in regard to venereal diseases. These sociosexual attitudes, and the sense of shame involved, are linked to very old social and religious antisexual traditions. Some efforts have been made in the direction of sex education in the schools, notably with the very popular book by Pondelickova-Maslova.

2015-12-01
The NASA AE-8/AP-8 has been the standard geospace environment specification for decades. This model describes the energetic particle environment around the Earth and is currently the default model used in the design of space missions at the Jet Propulsion Laboratory (JPL). Moreover, the model plays a critical role in the determination of the shielding and survivability of the satellites orbiting our planet. A recent update supported by the Air Force Research Laboratory (AFRL) and the National Reconnaissance Office (NRO), the AE-9/AP-9 model, was released in September 2012 and included many improvements like increased spatial resolution and the specification of the uncertainty due to instrument errors or space weather variability. A current effort at JPL is in place with the objective of making a decision within the Laboratory on the transition from AE-8/AP-8 to the new AE-9/AP-9. In this study we present the results of this effort, which involves the comparison between both versions of the model for different satellite orbits, the comparison between AE-9/AP-9 and in-situ satellite data from the Van Allen Probes and the OSTM/Jason 2 satellite, and the implications of adopting the new model for spacecraft design in terms of survivability, shielding, single event effects, and spacecraft charging.
International perspectives on sharing clinical data with patients.

Engaging patients in their care has become a topic of increasing importance, and enabling patients to have access to their clinical data is a key aspect of such engagement. We investigated, on an international scale, the current state of approaches for providing patients with access to their own clinical information. Individuals from 28 countries were invited to participate in a cross-sectional semi-structured interview. Interview questions focused on social and cultural influences that affected patient engagement activities, government support for current and planned initiatives, data ownership models, and technical issues. Interviews were conducted with individuals from 16 countries representing six continents. Respondents reported substantive initiatives for providing information to patients in the majority of countries interviewed. These initiatives were diverse in nature and stage of implementation. Enabling patient access to data is occurring on an international scale. There is considerable variability in the level of maturity, the degree of government involvement, the technical infrastructure, and the plans for future development across the world. As informaticians, we are still in the early stages of deploying patient engagement technologies and have yet to identify optimal strategies in this arena. Efforts to improve patient access to data are active on a global-scale. There are many open questions about best practices and much can be learned by adopting an international perspective to guide future implementation efforts. Copyright © 2015 Elsevier Ireland Ltd.

Improving Flash Flood Prediction in Multiple Environments

Flash flooding is a major concern in many fast responding headwater catchments . There are many efforts to model and to predict these flood events, though it is not currently possible to adequately predict the nature of flash flood events with a single model, and furthermore, many of these efforts do not even consider snow, which can, by itself, or in combination with rainfall events, cause destructive floods. The current research is aimed at broadening the applicability of flash flood modeling. Specifically, we will take a state of the art flash flood model that is designed to work with warm season precipitation in arid environments, the KINematic runoff and EROSion model (KINEROS2), and combine it with a continuous subsurface flow model and an energy balance snow model. This should improve its predictive capacity in humid environments where lateral subsurface flow significantly contributes to streamflow, and it will make possible the prediction of flooding events that involve rain-on-snow or rapid snowmelt. By modeling changes in the hydrologic state of a catchment before a flood begins, we can also better understand the factors or combination of factors that are necessary to produce large floods. Broadening the applicability of an already state of the art flash flood model, such as KINEROS2, is logical because flash floods can occur in all types of environments, and it may lead to better predictions, which are necessary to preserve life and property.

Quality improvement involves a combined effort among health care staff and stakeholders to diagnose and treat problems in the health care system. However, health care professionals often lack training in quality improvement methods, which makes it challenging to participate in improvement efforts. This article familiarizes health care professionals with how to begin a quality improvement project. The initial steps involve forming an improvement team that possesses expertise in the quality of care problem, leadership, and change management. Stakeholder mapping and analysis are useful tools at this stage, and these are reviewed to help identify individuals who might have a vested interest in the project. Physician engagement is a particularly important component of project success, and the knowledge that patients/caregivers can offer as members of a quality improvement team should not be overlooked. After a team is formed, an improvement framework helps to organize the scientific process of system change. Common quality improvement frameworks include Six Sigma, Lean, and the Model for Improvement. These models are contrasted, with a focus on the Model for Improvement, because it is widely used and applicable to a variety of quality of care problems without advanced training. It involves three steps: setting aims to focus improvement, choosing a balanced set of measures to determine if improvement occurs, and testing new ideas to change the current process. These new ideas are evaluated using Plan-Do-Study-Act cycles, where knowledge is gained by testing changes and reflecting on their effect. To show the real world utility of the quality improvement methods discussed, they are applied to a hypothetical quality improvement initiative that aims to promote home dialysis (home hemodialysis and peritoneal dialysis). This provides an example that kidney health care professionals can use to begin their own quality improvement projects. Copyright © 2016 by the American Society of Nephrology.

MO-D-218-01: Overview of Methodology and Standards (QIBA, IEC, AIUM and AAPM).
Carson, P
2012-06-01
Ultrasound system standards and professional guidelines can facilitate efficient provision of medical physics services and growth of ultrasound imaging if the documents are well designed and are utilized. We too often develop our own phantoms and procedures and never converge to obtain a critical mass of data on system performance and value of such services. Standards can also produce unnecessary costs and limit innovation if not carefully developed, reviewed, and changed as needed. There are quite a few new initiatives that, if followed vigorously, could improve medical ultrasound and medical physicists' contributions thereto. This talk is to explain many of the existing standards and recommendations for ultrasound system quality control, performance evaluation, and safety, as well as current and suggested efforts in these areas. The primary standards body for medical ultrasound systems is now the International Electrotechnical Commission (IEC). Uniformity across the world is helpful to all if the documents are reasonably current. There still is a role for traditional bodies such as the AAPM with its valuable report series and the American Inst. of Ultras. in Med. (AIUM) with its own standards and reports and its joint work with the Medical Imaging Technology Alliance (MITA). All three, with strong involvement of FDA scientists and with some efforts from the Acoustical Society of America have historically provided the main standards affecting medical physicists. Now that the lengthy IEC process is moving more smoothly, our national bodies still can provide new developments and drafts that can be offered as needed for international standardization. The ACR in particular can provide meaningful incentives through ultrasound service accreditation. Without any regulatory or strong consumer push, reports and standards on ultrasound system performance have received only modest use in the USA. A consistent consumer or accreditation push might be justified now. A series of three standards on performance evaluation is well on its way to covering pulse echo ultrasound well, with IEC 61319-1 on spatial measurements, IEC 61319-2 on depth of penetration and local dynamic range and one draft and one Technical Specification 62558 on small void imaging. A new effort has just been initiated to help drive more and better use of quantitative ultrasound imaging in human and surrogate studies and in clinical use. A shear wave speed ultrasound technical committee will carry out this effort in the Quantitative Imaging Biomarkers Alliance (QIBA) that is managed by the RSNA. 1. Understand the coverage of the two current and third planned IEC medical ultrasound performance evaluation standards that could form a basis for stable performance evaluation tests. 2. Understand the coverage of the Current AIUM and ACR QC documents and the drafting and support efforts in the IEC. 3. Understand the need for and partial availability of simplified software and instructions to improve and facilitate performance of these tests? 4. Understand how standards development can lead to improved understanding and performance of medical ultrasound imaging as is anticipated for the new QIBA effort. © 2012 American Association of Physicists in Medicine.

Since 1978, the Purdue University Agricultural Safety and Health Program has managed a surveillance effort and database to collect information on documented injuries and fatalities in all forms of U.S. agricultural confined spaces. The database currently contains 1,968 cases documented in the U.S. between 1964 and 2016. Of these cases, 174 (8.8%) involved entrapment or suffocation in grain transport vehicles (GTVs), including gravity-flow wagons, semi-truck trailers, and other agricultural transport vehicles that have limited access and are not considered normal work spaces or are classified as confined spaces. These GTV cases represent the overwhelming majority of documented cases involving all forms of agricultural transport vehicles, including forage and manure transport vehicles. Of the incidents documented, 64.3% resulted in fatalities and 71.8% involved children and youth age 20 years and under, when the age was determined. For the GTV cases, the typical victim was male (88.5%), and the average age of the victim was 19.9 (median 12), with over 63.5% of the cases involving children under the age of 15. In numerous incidents, more than one victim became entrapped, including one incident involving five victims. The number of documented cases decreased sharply from a peak of approximately 7 cases per year in the early 1990s to an average of 3.1 cases per year over the past two decades, with no cases documented in 1998 and 2013. However, there is a linear increase in the frequency of incidents since the first case was documented in 1964. This trend is partially due to peaks in 2011 and 2014, when 10 and 9 cases, respectively, were documented, along with more vigilant surveillance methods due to online search capabilities. The general decline, more recently, in the annual number of cases is attributed to increased awareness of the hazards to youth during transport in GTVs, increased use of warnings on GTVs, and the increased size of GTVs, which makes human access more difficult and less practical. Efforts over the past decade to bring attention to the risk of entrapment in GTVs should be recognized as a success of the educational and technological strategies initiated due to earlier high-profile incidents. However, with 6, 10, 9, and 4 cases documented in 2010, 2011, 2014, and 2016, respectively, continued efforts to address the problem are justified. Recommendations for future actions include development of a safety standard for GTVs that includes placement of safety messages on all new GTVs, use of windows above outlets, retrofitting older GTVs with appropriate warnings, and continuing to address the hazard with safety resources targeting all workers exposed to grain handling and transport.

We need all sectors of society involved in reducing obesity. The food industry's effort to reduce energy intake as part of the Healthy Weight Commitment Foundation is a significant step in the right direction and should be recognized as such by the public health community. We also need to get organizations that promote physical inactivity, such as computer, automobile, and entertainment industries, to become engaged in efforts to reduce obesity. © 2014 The Obesity Society.
Management strategies in pancreatic cancer.
Campen, Christopher J; Dragovich, Tomislav; Baker, Amanda F
2011-04-01
Current first-line and adjuvant chemotherapeutic strategies for management of patients with pancreatic cancer are reviewed. Pancreatic adenocarcinoma is the 10th most prevalent cancer and the fourth most common cause of cancer deaths in the United States. More than 80% of patients with pancreatic cancer are diagnosed with locally advanced or metastatic disease and are not candidates for surgery; these patients often require multimodal treatment. The most widely used chemotherapy for such patients, as well as patients requiring adjuvant therapy after surgery, is gemcitabine or gemcitabine-based chemotherapy. All current chemotherapies for pancreatic cancer are associated with dose-limiting hematologic toxicity and other adverse effects that require ongoing monitoring and dosage adjustment to balance the benefits and risks of treatment. Pharmacists can play an important role in monitoring and providing drug information and guidance to patients and oncologists. Current investigational strategies include efforts to improve chemotherapy response rates and outcomes through modulation of cell signaling pathways and use of nanotechnology to improve drug delivery. Current management of pancreatic cancer is multifaceted, involving anticancer therapy, supportive care, and toxicity management. Standard systemic therapy with gemcitabine as a single agent or in combination with other cytotoxic agents provides modest benefits in terms of response and symptom control.

A broad assessment is provided of the current state of knowledge regarding the risks associated with shale gas development and their governance. For the principal domains of risk, we identify observed and potential hazards and promising mitigation options to address them, characterizing current knowledge and research needs. Important unresolved research questions are identified for each area of risk; however, certain domains exhibit especially acute deficits of knowledge and attention, including integrated studies of public health, ecosystems, air quality, socioeconomic impacts on communities, and climate change. For these, current research and analysis are insufficient to either confirm or preclude important impacts. The rapidly evolving landscape of shale gas governance in the U.S. is also assessed, noting challenges and opportunities associated with the current decentralized (state-focused) system of regulation. We briefly review emerging approaches to shale gas governance in other nations, and consider new governance initiatives and options in the U.S. involving voluntary industry certification, comprehensive development plans, financial instruments, and possible future federal roles. In order to encompass the multiple relevant disciplines, address the complexities of the evolving shale gas system and reduce the many key uncertainties needed for improved management, a coordinated multiagency federal research effort will need to be implemented.
Spheromaks, solar prominences, and Alfvén instability of current sheets

2001-06-01
Three related efforts underway at Caltech are discussed: experimental studies of spheromak formation, experimental simulation of solar prominences, and Alfvén wave instability of current sheets. Spheromak formation has been studied by using a coaxial magnetized plasma gun to inject helicity-bearing plasma into a very large vacuum chamber. The spheromak is formed without a flux conserver and internal λ profiles have been measured. Spheromak-based technology has been used to make laboratory plasmas having the topology and dynamics of solar prominences. The physics of these structures is closely related to spheromaks (low β, force-free, relaxed state equilibrium) but the boundary conditions and symmetry are different. Like spheromaks, the equilibrium involves a balance between hoop forces, pinch forces, and magnetic tension. It is shown theoretically that if a current sheet becomes sufficiently thin (of the order of the ion skin depth or smaller), it becomes kinetically unstable with respect to the emission of Alfvén waves and it is proposed that this wave emission is an important aspect of the dynamics of collisionless reconnection.

Biochar is the solid byproduct from the pyrolysis of agricultural crop residues, manures, green wastes and wood-based materials. Pyrolyzing biomass causes inorganic and organic compounds to be concentrated within the carbonized remains of the original lignin and cellulose structure. It is through this complex mixture of organic aromatic structures and inorganic elements that potentially imparts biochars with special multi-functional capabilities. Our current research has focused on developing biochar to simultaneously sequester soil carbon and remediate degraded soils. This is accomplished by directly improving soil nutrient and moisture contents, sorbing pollutants, as well as altering microbial signaling. Maintaining these improvements needs to account for biochar physical degradation, which may be overcome by biochar-mineral associations. Additional research is focused on biochar use that minimizes soil microorganism population shifts in order to maintain current ecosystem services. Future USDA research involves more evaluations to understand the multifunctional role of biochar in the agricultural and environmental sectors (e.g., USEPA superfund locations). This presentation will provide highlights of current and future coordinated biochar research efforts from several key laboratory locations across the US.
Quality improvement: the nurse's role.
Moran, M J; Johnson, J E
1992-06-01
Continuous quality improvement is a concept which includes: Quality assurance--the provision of services that meet an appropriate standard. Problem resolution--including all departments involved in the issue at hand. Quality improvement--a continuous process involving all levels of the organization working together across departmental lines to produce better services for health care clients. Deming (1982b) and others have espoused total system reform to achieve quality improvement--not merely altering the current system, but radically changing it. It must be assumed that those who provide services at the staff level are acting in good faith and are not willfully failing to do what is correct (Berwick, 1991). Those who perform direct services are in an excellent position to identify the need for change in service delivery processes. Based on this premise, the staff nurse--who is at the heart of the system--is the best person to assess the status of health care services and to work toward improving the processes by which these services are provided to clients in the health care setting. The nurse manager must structure the work setting to facilitate the staff nurse's ability to undertake constructive action for improving care. The use of quality circles, quality councils, or quality improvement forums to facilitate the coordination of quality improvement efforts is an effective way to achieve success. The QA coordinator assists departments in documenting that the quality improvement efforts are effective across all departments of the organization, and aggregates data to demonstrate that they meet the requirements of external regulatory agencies, insurers, and professional standards. The nurse executive provides the vision and secures the necessary resources to ensure that the organization's quality improvement efforts are successful. By inspiring and empowering the staff in their efforts to improve the process by which health care is provided, nurse managers participate in reshaping the health care environment. The professional nurse plays a vital role in the quality improvement of health care services. However, nurses cannot make these improvements in a vacuum; they must include other professionals and ancillary personnel in their efforts. Total quality commitment must include all levels of an organization's structure. Quality patient care services will be achieved as the result of positive interactions among departments working together to build a dynamic mechanism that continuously improves the processes and outcomes of health care services.

Consumer participation in decision-making about service planning is common in certain health services in Australia but is thought to be largely underdeveloped in drug treatment services. This paper (1) describes the current practices within Australian drug treatment services that aim to include consumers in service planning and provision; and (2) determines how much consumers know about the existing opportunities for involvement. Sixty-four randomly selected service providers (representing 64 separate services) completed interviews about the current arrangements for consumer participation within their services (response rate = 82%). A total of 179 consumers completed interviews assessing their knowledge of the consumer participation activities available at the service they attended. Consumer participation activities were not uncommon in drug treatment services, although the existing activities were concerned largely with providing information to or receiving information from consumers. Activities that included consumers in higher forms of involvement, such as those in which consumers took part in decision-making, were largely uncommon. Consumers had a considerable lack of knowledge about the participation activities available to them, revealing a lack of communication between providers and consumers. While service providers were making efforts to engage consumers in service planning and provision (despite the general lack of State or Commonwealth policy directives and extra funding to do so), these appear ineffectual because of poor communication between providers and consumers. As a starting point, a critical part of any meaningful consumer participation initiative must include systems to ensure that consumers know about available opportunities.

Active engagement of scientists in Education and Public Outreach (E/PO) activities results in benefits for both the audience and scientists. Most scientists are trained in research but have little formal training in education. The Planetary Science Education and Public Outreach (E/PO) Forum helps the Science Mission Directorate support scientists currently involved in E/PO and to help scientists who are interested in becoming involved in E/PO efforts find ways to do so through a variety of avenues. We will present current and future opportunities and resources for scientists to become engaged in education and public outreach. These include upcoming NASA SMD E/PO funding opportunities, professional development resources for writing NASA SMD E/PO proposals (webinars and other online tools), toolkits for scientists interested in best practices in E/PO (online guides for K-12 education and public outreach), EarthSpace (a community web space where instructors can find and share about teaching space and earth sciences in the undergraduate classroom, including class materials news and funding opportunities, and the latest education research), thematic resources for teaching about the solar system (archived resources from Year of the Solar System), and an online database of scientists interested in connecting with education programs.

Revisions to the JDL data fusion model
NASA Astrophysics Data System (ADS)
Steinberg, Alan N.; Bowman, Christopher L.; White, Franklin E.
1999-03-01
The Data Fusion Model maintained by the Joint Directors of Laboratories (JDL) Data Fusion Group is the most widely-used method for categorizing data fusion-related functions. This paper discusses the current effort to revise the expand this model to facilitate the cost-effective development, acquisition, integration and operation of multi- sensor/multi-source systems. Data fusion involves combining information - in the broadest sense - to estimate or predict the state of some aspect of the universe. These may be represented in terms of attributive and relational states. If the job is to estimate the state of a people, it can be useful to include consideration of informational and perceptual states in addition to the physical state. Developing cost-effective multi-source information systems requires a method for specifying data fusion processing and control functions, interfaces, and associate databases. The lack of common engineering standards for data fusion systems has been a major impediment to integration and re-use of available technology: current developments do not lend themselves to objective evaluation, comparison or re-use. This paper reports on proposed revisions and expansions of the JDL Data FUsion model to remedy some of these deficiencies. This involves broadening the functional model and related taxonomy beyond the original military focus, and integrating the Data Fusion Tree Architecture model for system description, design and development.
Bringing ayahuasca to the clinical research laboratory.
Riba, Jordi; Barbanoj, Manel J
2005-06-01
Since the winter of 1999, the authors and their research team have been conducting clinical studies involving the administration of ayahuasca to healthy volunteers. The rationale for conducting this kind of research is twofold. First, the growing interest of many individuals for traditional indigenous practices involving the ingestion of natural psychotropic drugs such as ayahuasca demands the systematic study of their pharmacological profiles in the target species, i.e., human beings. The complex nature of ayahuasca brews combining a large number of pharmacologically active compounds requires that research be carried out to establish the safety and overall pharmacological profile of these products. Second, the authors believe that the study of psychedelics in general calls for renewed attention. Although the molecular and electrophysiological level effects of these drugs are relatively well characterized, current knowledge of the mechanisms by which these compounds modify the higher order cognitive processes in the way they do is still incomplete, to say the least. The present article describes the development of the research effort carried out at the Autonomous University of Barcelona, commenting on several methodological aspects and reviewing the basic clinical findings. It also describes the research currently underway in our laboratory, and briefly comments on two new studies we plan to undertake in order to further our knowledge of the pharmacology of ayahuasca.
Urothelium update: how the bladder mucosa measures bladder filling.
Janssen, D A W; Schalken, J A; Heesakkers, J P F A
2017-06-01
This review critically evaluates the evidence on mechanoreceptors and pathways in the bladder urothelium that are involved in normal bladder filling signalling. Evidence from in vitro and in vivo studies on (i) signalling pathways like the adenosine triphosphate pathway, cholinergic pathway and nitric oxide and adrenergic pathway, and (ii) different urothelial receptors that are involved in bladder filling signalling like purinergic receptors, sodium channels and TRP channels will be evaluated. Other potential pathways and receptors will also be discussed. Bladder filling results in continuous changes in bladder wall stretch and exposure to urine. Both barrier and afferent signalling functions in the urothelium are constantly adapting to cope with these dynamics. Current evidence shows that the bladder mucosa hosts essential pathways and receptors that mediate bladder filling signalling. Intracellular calcium ion increase is a dominant factor in this signalling process. However, there is still no complete understanding how interacting receptors and pathways create a bladder filling signal. Currently, there are still novel receptors investigated that could also be participating in bladder filling signalling. Normal bladder filling sensation is dependent on multiple interacting mechanoreceptors and signalling pathways. Research efforts need to focus on how these pathways and receptors interact to fully understand normal bladder filling signalling. © 2016 Scandinavian Physiological Society.

Twenty-First Century Pathologists' Advocacy.
Allen, Timothy Craig
2017-07-01
Pathologists' advocacy plays a central role in the establishment of continuously improving patient care quality and patient safety, and in the maintenance and progress of pathology as a profession. Pathology advocacy's primary goal is the betterment of patient safety and quality medical care; however, payment is a necessary and appropriate component to both, and has a central role in advocacy. Now is the time to become involved in pathology advocacy; the Medicare Access and Children's Health Insurance Program (CHIP) Reauthorization Act of 2015 (MACRA) and the Protecting Access to Medicare Act of 2014 (PAMA) are 2 of the most consequential pieces of legislation impacting the pathology and laboratory industry in the last 20 years. Another current issue of far-reaching impact for pathologists is balance billing, and yet many pathologists have little or no understanding of balance billing. Pathologists at all stages of their careers, and in every professional setting, need to participate. Academic pathologists have a special obligation to, if not become directly involved in advocacy, at least have a broad and current understanding of those issues, as well as the need and responsibility of pathologists to actively engage in advocacy efforts to address them, in order to teach residents the place of advocacy, and its value, as an inseparable and indispensable component of their professional responsibilities.
Predicting the risk of sudden cardiac death.
Lerma, Claudia; Glass, Leon
2016-05-01
Sudden cardiac death (SCD) is the result of a change of cardiac activity from normal (typically sinus) rhythm to a rhythm that does not pump adequate blood to the brain. The most common rhythms leading to SCD are ventricular tachycardia (VT) or ventricular fibrillation (VF). These result from an accelerated ventricular pacemaker or ventricular reentrant waves. Despite significant efforts to develop accurate predictors for the risk of SCD, current methods for risk stratification still need to be improved. In this article we briefly review current approaches to risk stratification. Then we discuss the mathematical basis for dynamical transitions (called bifurcations) that may lead to VT and VF. One mechanism for transition to VT or VF involves a perturbation by a premature ventricular complex (PVC) during sinus rhythm. We describe the main mechanisms of PVCs (reentry, independent pacemakers and abnormal depolarizations). An emerging approach to risk stratification for SCD involves the development of individualized dynamical models of a patient based on measured anatomy and physiology. Careful analysis and modelling of dynamics of ventricular arrhythmia on an individual basis will be essential in order to improve risk stratification for SCD and to lay a foundation for personalized (precision) medicine in cardiology. © 2015 The Authors.

Social work interventions in health care, particularly those that involve working with people being treated for chronic and life-threatening conditions, frequently involve efforts to educate patients about their disease, treatment options, safety planning, medical adherence, and other associated issues. Despite an intuitive notion that patients access information about all of these issues through a variety of media-both inside and outside the clinical encounter, created by professionals and by others-there currently exists no validated means of assessing patients' use of these forms of information. To address this gap, authors first created candidate item measures with input from both physicians and a small group of diverse patients who currently have an implantable cardioverter defibrillator (ICD), a sophisticated cardiac device for which a trajectory model of social work intervention was recently outlined. Authors then surveyed a group of 205 individuals who have these devices, assessing their use of various media to learn about ICDs. They then conducted factor and item analysis to refine and remove poorly performing items while delineating forms of media use by type. The resultant preliminary measure of informational media use can be further refined and adapted for use with any clinical population. © 2017 National Association of Social Workers.

This paper describes a second generation Simulator for Engineering Ethics Education. Details describing the first generation activities of this overall effort are published in Chung and Alfred (Sci Eng Ethics 15:189-199, 2009). The second generation research effort represents a major development in the interactive simulator educational approach. As with the first generation effort, the simulator places students in first person perspective scenarios involving different types of ethical situations. Students must still gather data, assess the situation, and make decisions. The approach still requires students to develop their own ability to identify and respond to ethical engineering situations. However, were as, the generation one effort involved the use of a dogmatic model based on National Society of Professional Engineers' Code of Ethics, the new generation two model is based on a mathematical model of the actual experiences of engineers involved in ethical situations. This approach also allows the use of feedback in the form of decision effectiveness and professional career impact. Statistical comparisons indicate a 59 percent increase in overall knowledge and a 19 percent improvement in teaching effectiveness over an Internet Engineering Ethics resource based approach.

The Planetary Science Education and Public Outreach (E/PO) Forum is charged by NASA's Science Mission Directorate (SMD) with engaging, extending, and supporting the community of E/PO professionals and scientists involved in planetary science education activities in order to help them more effectively and efficiently share NASA science with all learners. A number of resources and opportunities for involvement are available for planetary scientists involved in - or interested in being involved in - E/PO. The Forum provides opportunities for community members to stay informed, communicate, collaborate, leverage existing programs and partnerships, and become more skilled education practitioners. Interested planetary scientists can receive newsletters, participate in monthly calls, interact through an online community workspace, and attend annual E/PO community meetings and meetings of opportunity at science and education conferences. The Forum also provides professional development opportunities on a myriad of topics, from common pre-conceptions in planetary science to program evaluation, to delivering effective workshops. Thematic approaches, such as the Year of the Solar System (http://solarsystem.nasa.gov/yss), are coordinated by the Forum; through these efforts resources are presented topically, in a manner that can be easily ported into diverse learning environments. Information about the needs of audiences with which scientists interact - higher education, K-12 education, informal education, and public - currently is being researched by SMD's Audience-Based Working Groups. Their findings and recommendations will be made available to inform the activities and products of E/PO providers so they are able to better serve these audiences. Also in production is a "one-stop-shop" of SMD E/PO products and resources that can be used in conjunction with E/PO activities. Further supporting higher-education efforts, the Forum coordinates a network of planetary science faculty, bringing them together at science conferences to share resources and experiences and to discuss pertinent education research. An online higher education clearinghouse, (EarthSpace - http://www.lpi.usra.edu/earthspace), has been developed to provide faculty with news and funding information, the latest education research and resources for teaching undergraduates, and undergraduate course materials, including lectures, labs, and homework. The presentation will explore the Planetary Science E/PO Forum pathways and tools available to support scientists involved in - or interested in being involved in - E/PO.

A world-wide effort is now being pursued towards the development of flavors and fragrances (F&F) production independently from traditional sources, as well as autonomously from depleting fossil fuel supplies. Biotechnological production of F&F by microbes has emerged as a vivid solution to the current market limitations. Amongst a wide variety of fragrant chemicals, 2-PE is of significant interest to both scientific and industrial community. Although the general overview of the 2-PE synthesis pathway is commonly known, involvement of particular molecular identities in this pathway has not been elucidated in Yarrowia lipolytica to date. The aim of this study was mapping molecular identities involved in 2-PE synthesis in Y. lipolytica. To acquire a comprehensive landscape of the proteins that are directly and indirectly involved in L-Phe degradation and 2-PE synthesis, we took advantage of comprehensibility and sensitivity of high-throughput LC-MS/MS-quantitative analysis. Amongst a number of proteins involved in amino acid turnover and the central carbon metabolism, enzymes involved in L-Phe conversion to 2-PE have been identified. Results on yeast-to-hyphae transition in relation to the character of the provided nitrogen source have been presented. © FEMS 2015. All rights reserved.

Impairments in willingness to exert effort contribute to the motivational deficits characteristic of the negative symptoms of schizophrenia. The current study evaluated the psychometric properties of 5 new or adapted paradigms to determine their suitability for use in clinical trials of schizophrenia. This study included 94 clinically stable participants with schizophrenia and 40 healthy controls. The effort-based decision-making battery was administered twice to the schizophrenia group (baseline, 4-week retest) and once to the control group. The 5 paradigms included 1 that assesses cognitive effort, 1 perceptual effort, and 3 that assess physical effort. Each paradigm was evaluated on (1) patient vs healthy control group differences, (2) test-retest reliability, (3) utility as a repeated measure (ie, practice effects), and (4) tolerability. The 5 paradigms showed varying psychometric strengths and weaknesses. The Effort Expenditure for Rewards Task showed the best reliability and utility as a repeated measure, while the Grip Effort Task had significant patient-control group differences, and superior tolerability and administration duration. The other paradigms showed weaker psychometric characteristics in their current forms. These findings highlight challenges in adapting effort and motivation paradigms for use in clinical trials.

Experimental supersonic combustion research related to hypersonic airbreathing propulsion has been actively underway at NASA Langley Research Center (LaRC) since the mid-1960's. This research involved experimental investigations of fuel injection, mixing, and combustion in supersonic flows and numerous tests of scramjet engine flowpaths in LaRC test facilities simulating flight from Mach 4 to 8. Out of this research effort has come scramjet combustor design methodologies, ground test techniques, and data analysis procedures. These technologies have progressed steadily in support of the National Aero-Space Plane (NASP) program and the current Hyper-X flight demonstration program. During NASP nearly 2500 tests of 15 scramjet engine models were conducted in LaRC facilities. In addition, research supporting the engine flowpath design investigated ways to enhance mixing, improve and apply nonintrusive diagnostics, and address facility operation. Tests of scramjet combustor operation at conditions simulating hypersonic flight at Mach numbers up to 17 also have been performed in an expansion tube pulse facility. This paper presents a review of the LaRC experimental supersonic combustion research efforts since the late 1980's, during the NASP program, and into the Hyper-X Program.
Evaluation of ground motion scaling methods for analysis of structural systems
O'Donnell, A. P.; Beltsar, O.A.; Kurama, Y.C.; Kalkan, E.; Taflanidis, A.A.
2011-01-01
Ground motion selection and scaling comprises undoubtedly the most important component of any seismic risk assessment study that involves time-history analysis. Ironically, this is also the single parameter with the least guidance provided in current building codes, resulting in the use of mostly subjective choices in design. The relevant research to date has been primarily on single-degree-of-freedom systems, with only a few studies using multi-degree-of-freedom systems. Furthermore, the previous research is based solely on numerical simulations with no experimental data available for the validation of the results. By contrast, the research effort described in this paper focuses on an experimental evaluation of selected ground motion scaling methods based on small-scale shake-table experiments of re-configurable linearelastic and nonlinear multi-story building frame structure models. Ultimately, the experimental results will lead to the development of guidelines and procedures to achieve reliable demand estimates from nonlinear response history analysis in seismic design. In this paper, an overview of this research effort is discussed and preliminary results based on linear-elastic dynamic response are presented. ?? ASCE 2011.

The Precision Medicine Initiative recently announced by President Barack Obama seeks to move the field of precision medicine more rapidly into clinical care. Precision medicine revolves around the concept of integrating individual-level data including genomics, biomarkers, lifestyle and other environmental factors, wearable device physiological data, and information from electronic health records to ultimately provide better clinical care to individual patients. The Precision Medicine Initiative as currently structured will primarily fund efforts in cancer genomics with longer-term goals of advancing precision medicine to all areas of health, and will be supported through creation of a 1 million person cohort study across the United States. This focused effort on precision medicine provides scientists, clinicians, and patients within the cardiovascular community an opportunity to work together boldly to advance clinical care; the community needs to be aware and engaged in the process as it progresses. This article provides a framework for potential involvement of the cardiovascular community in the Precision Medicine Initiative, while highlighting significant challenges for its successful implementation. © 2016 American Heart Association, Inc.

The complete calibration of the color-redshift relation (C3R2) survey is a multi-institution, mutli-instrument survey with the Keck telescopes that aims to map out the empirical galaxy color-redshift relation in preparation for the Stage IV dark energy missions Euclid and WFIRST. A key challenge for weak lensing cosmology with these missions will be measuring highly accurate redshift distributions for billions of faint galaxies using only broad-band photometric observations. Well-calibrated photometric redshifts will thus be critical to their success. C3R2 uses an innovative technique that maps the color distribution of galaxies in the high-dimensional color space (u-g, ..., J-H) expected for Euclid and WFIRST, allowng us to focus spectroscopic effort on those regions of galaxy color space which are currently unexplored. C3R2 is a joint effort involving all of the Keck partners, with 44.5 nights allocated thus far. DR1 is published (Masters, Stern, Cohen et al, ApJ, 841, 111), and DR2, with > 3000 new redshifts, will be submitted in mid 2018.
On the need for a national radiological response plan in Egypt

Use of radioactive materials and sources is increasing within the Arab Republic of Egypt. With this increase comes a need to prepare for accidents involving these materials. For years there has been an informal agreement between the National Centre for Nuclear Safety and Radiation Control (NCNSRC), one of the four centers operated by the Atomic Energy Agency (AEA), and the Civil Defense Authority (CDA) to cooperate in a radiological emergency. CDA currently has the responsibility for responding to all types of emergencies. The increasing use of radioactive materials and the complexity of the response required by accidents creates a needmore » for a more formal arrangement. In response to the increasing possibility of radiation accidents in or near Egypt, the government is preparing the {ital Egyptian Emergency Response Plan for Radiological Accidents} to coordinate the response efforts of the national agencies. This plan, which is now being finalized, provides information on agency roles and responsibilities during a response. The plan will also provide a basis for initiating training, planning for emergency public information, and developing public education efforts.« less

The production of color images has grown in recent years due to the impact of digital technology. Access and equipment affordability are now bringing a new generation of color producers into the marketplace. Many traditional questions concerning color attributes are repeatedly asked by individuals: color fidelity, quality, measurements and device characterization pose daily dilemmas. Curriculum components should be offered in an educational environment that enhance the color foundations required of knowledgeable managers, researchers and technicians. The printing industry is adding many of the new digital color technologies to their vocabulary pertinent to color production. This paper presents current efforts being made to integrate color knowledge in a four year program of undergraduate study. Specific topics include: color reproduction, device characterization, material characterization and the role of measurements as a linking attribute. This paper also provides information detailing efforts to integrate color specification/measurement and analysis procedures used by students and subsequent application in color image production are provided. A discussion of measurement devices used in the learning environment is also presented. The investigation involves descriptive data on colorants typically used in printing inks and color.

Istanbul, with a population of around 13 million people, is located between Europe and Asia and is the biggest city in Turkey. Metropolitan Istanbul produces about 14,000 tons of solid waste per day. The aim of this study was to assess the situation of municipal solid-waste (MSW) management in Istanbul. This was achieved by reviewing the quantity and composition of waste produced in Istanbul. Current requirements and challenges in relation to the optimization of Istanbul's MSW collection and management system are also discussed, and several suggestions for solving the problems identified are presented. The recovery of solid waste from the landfills, as well as the amounts of landfill-generated biogas and electricity, were evaluated. In recent years, MSW management in Istanbul has improved because of strong governance and institutional involvement. However, efforts directed toward applied research are still required to enable better waste management. These efforts will greatly support decision making on the part of municipal authorities. There remains a great need to reduce the volume of MSW in Istanbul. 2010 Elsevier Ltd. All rights reserved.
Adaptive seamless designs: selection and prospective testing of hypotheses.
Jennison, Christopher; Turnbull, Bruce W
2007-01-01
There is a current trend towards clinical protocols which involve an initial "selection" phase followed by a hypothesis testing phase. The selection phase may involve a choice between competing treatments or different dose levels of a drug, between different target populations, between different endpoints, or between a superiority and a non-inferiority hypothesis. Clearly there can be benefits in elapsed time and economy in organizational effort if both phases can be designed up front as one experiment, with little downtime between phases. Adaptive designs have been proposed as a way to handle these selection/testing problems. They offer flexibility and allow final inferences to depend on data from both phases, while maintaining control of overall false positive rates. We review and critique the methods, give worked examples and discuss the efficiency of adaptive designs relative to more conventional procedures. Where gains are possible using the adaptive approach, a variety of logistical, operational, data handling and other practical difficulties remain to be overcome if adaptive, seamless designs are to be effectively implemented.
Feline Immunodeficiency Virus in South America

2012-01-01
The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV) have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species). Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV) causes an immune system disease in domestic cats (Felis catus) involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs) in South America. PMID:22590677

Several major airports around the United States have, or plan to have, closely-spaced parallel runways. This project complemented current and previous research by examining the pilots ability to control their position longitudinally within their approach stream.This project s results considered spacing for separation from potential positions of wake vortices from the parallel approach. This preventive function could enable CSPA operations to very closely spaced runways. This work also considered how pilot involvement in longitudinal spacing could allow for more efficient traffic flow, by allowing pilots to keep their aircraft within tighter arrival slots then air traffic control (ATC) might be able to establish, and by maintaining space within the arrival stream for corresponding departure slots. To this end, this project conducted several research studies providing an analytic and computational basis for calculating appropriate aircraft spacings, experimental results from a piloted flight simulator test, and an experimental testbed for future simulator tests. The following sections summarize the results of these three efforts.

Future space missions will require more sophisticated power systems, implying higher costs and more extensive crew and ground support involvement. To decrease this human involvement, as well as to protect and most efficiently utilize this important resource, NASA has undertaken major efforts to promote progress in the design and development of autonomously managed power systems. Two areas being actively pursued are autonomous power system (APS) breadboards and knowledge-based expert system (KBES) applications. The former are viewed as a requirement for the timely development of the latter. Not only will they serve as final testbeds for the various KBES applications, but will play a major role in the knowledge engineering phase of their development. The current power system breadboard designs are of a distributed microprocessor nature. The distributed nature, plus the need to connect various external computer capabilities (i.e., conventional host computers and symbolic processors), places major emphasis on effective networking. The communications and networking technologies for the first power system breadboard/test facility are described.

Biotin (vitamin H) is one of the most fascinating cofactors involved in central pathways in pro- and eukaryotic cell metabolism. Since its original discovery in 1901, research has led to the discovery of the complete biotin biosynthesis pathways in many different microbes and much work has been done on the highly intriguing and complex biochemistry of biotin biosynthesis. While humans and animals require several hundred micrograms of biotin per day, most microbes, plants and fungi appear to be able to synthesize the cofactor themselves. Biotin is added to many food, feed and cosmetic products, creating a world market of 10-30 t/year. However, the majority of the biotin sold is synthesized in a chemical process. Since the chemical synthesis is linked with a high environmental burden, much effort has been put into the development of biotin-overproducing microbes. A summary of biotin biosynthesis and its biological role is presented; and current strategies for the improvement of microbial biotin production using modern biotechnological techniques are discussed.
Ion channels of the mammalian urethra
Kyle, Barry D
2014-01-01
The mammalian urethra is a muscular tube responsible for ensuring that urine remains in the urinary bladder until urination. In order to prevent involuntary urine leakage, the urethral musculature must be capable of constricting the urethral lumen to an extent that exceeds bladder intravesicular pressure during the urine-filling phase. The main challenge in anti-incontinence treatments involves selectively-controlling the excitability of the smooth muscles in the lower urinary tract. Almost all strategies to battle urinary incontinence involve targeting the bladder and as a result, this tissue has been the focus for the majority of research and development efforts. There is now increasing recognition of the value of targeting the urethral musculature in the treatment and management of urinary incontinence. Newly-identified and characterized ion channels and pathways in the smooth muscle of the urethra provides a range of potential therapeutic targets for the treatment of urinary incontinence. This review provides a summary of the current state of knowledge of the ion channels discovered in urethral smooth muscle cells that regulate their excitability. PMID:25483582
Unsteady Turbopump Flow Simulations

The objective of the current effort is two-fold: 1) to provide a computational framework for design and analysis of the entire fuel supply system of a liquid rocket engine; and 2) to provide high-fidelity unsteady turbopump flow analysis capability to support the design of pump sub-systems for advanced space transportation vehicle. Since the space launch systems in the near future are likely to involve liquid propulsion system, increasing the efficiency and reliability of the turbopump components is an important task. To date, computational tools for design/analysis of turbopump flow are based on relatively lower fidelity methods. Unsteady, three-dimensional viscous flow analysis tool involving stationary and rotational components for the entire turbopump assembly has not been available, at least, for real-world engineering applications. Present effort is an attempt to provide this capability so that developers of the vehicle will be able to extract such information as transient flow phenomena for start up, impact of non-uniform inflow, system vibration and impact on the structure. Those quantities are not readily available from simplified design tools. In this presentation, the progress being made toward complete turbo-pump simulation capability for a liquid rocket engine is reported. Space Shuttle Main Engine (SSME) turbo-pump is used as a test case for the performance evaluation of the hybrid MPI/Open-MP and MLP versions of the INS3D code. Relative motion of the grid system for rotor-stator interaction was obtained by employing overset grid techniques. Time-accuracy of the scheme has been evaluated by using simple test cases. Unsteady computations for SSME turbopump, which contains 106 zones with 34.5 Million grid points, are currently underway on Origin 2000 systems at NASA Ames Research Center. Results from these time-accurate simulations with moving boundary capability and the performance of the parallel versions of the code will be presented.

This paper will describe the technology development efforts NASA has underway for Automated Rendezvous and Docking/Capture (AR&D/C) sensors and a docking mechanism and the challenges involved. The paper will additionally address how these technologies will be extended to other missions requiring AR&D/C whether robotic or manned. NASA needs AR&D/C sensors for both the robotic and crewed segments of the Asteroid Redirect Mission (ARM). NASA recently conducted a commonality assessment of the concept of operations for the robotic Asteroid Redirect Vehicle (ARV) and the crewed mission segment using the Orion crew vehicle. The commonality assessment also considered several future exploration and science missions requiring an AR&D/C capability. Missions considered were asteroid sample return, satellite servicing, and planetary entry, descent, and landing. This assessment determined that a common sensor suite consisting of one or more visible wavelength cameras, a threedimensional LIDAR along with long-wavelength infrared cameras for robustness and situational awareness could be used on each mission to eliminate the cost of multiple sensor developments and qualifications. By choosing sensor parameters at build time instead of at design time and, without having to requalify flight hardware, a specific mission can design overlapping bearing, range, relative attitude, and position measurement availability to suit their mission requirements with minimal nonrecurring engineering costs. The resulting common sensor specification provides the union of all performance requirements for each mission and represents an improvement over the current systems used for AR&D/C today. These sensor specifications are tightly coupled to the docking system capabilities and requirements for final docking conditions. The paper will describe NASA's efforts to develop a standard docking system for use across NASA human spaceflight missions to multiple destinations. It will describe the current design status and the considerations and technologies involved in developing this docking mechanism.

There is increasing interest in making patient participation an integral component of medical research. However, practical guidance on optimizing this engagement in healthcare is scarce. Since 2002, patient involvement has been one of the key features of the Outcome Measures in Rheumatology (OMERACT) international consensus effort. Based on a review of cumulative data from qualitative studies and internal surveys among OMERACT participants, we explored the potential benefits and challenges of involving patient research partners in conferences and working group activities. We supplemented our review with personal experiences and reflections regarding patient participation in the OMERACT process. We found that between 2002 and 2016, 67 patients have attended OMERACT conferences, of whom 28 had sustained involvement; many other patients contributed to OMERACT working groups. Their participation provided face validity to the OMERACT process and expanded the research agenda. Essential facilitators have been the financial commitment to guarantee sustainable involvement of patients at these conferences, procedures for recruitment, selection and support, and dedicated time allocated in the program for patient issues. Current challenges include the representativeness of the patient panel, risk of pseudo-professionalization, and disparity in patients' and researchers' perception of involvement. In conclusion, OMERACT has embedded long-term patient involvement in the consensus-building process on the measurement of core health outcomes. This integrative process continues to evolve iteratively. We believe that the practical points raised here can improve participatory research implementation.

Effort-based decision-making paradigms are increasingly utilized to gain insight into the nature of motivation deficits. Research has shown associations between effort-based decision making and experiential negative symptoms; however, the associations are not consistent. The current study had two primary goals. First, we aimed to replicate previous findings of a deficit in effort-based decision making among individuals with schizophrenia on a test of cognitive effort. Second, in a large sample combined from the current and a previous study, we sought to examine the association between negative symptoms and effort by including the related construct of defeatist beliefs. The results replicated previous findings of impaired cognitive effort-based decision making in schizophrenia. Defeatist beliefs significantly moderated the association between negative symptoms and effort-based decision making such that there was a strong association between high negative symptoms and deficits in effort-based decision making, but only among participants with high levels of defeatist beliefs. Thus, our findings suggest the relationship between negative symptoms and effort performance may be understood by taking into account the role of defeatist beliefs, and finding that might explain discrepancies in previous studies.

The Structural Biology laboratory at NASA Marshall Spaceflight Center uses x-ray crystallographic techniques to conduct research into the three-dimensional structure of a wide variety of proteins. A major effort in the laboratory involves an ongoing study of human serum albumin (the principal protein in human plasma) and its interaction with various endogenous substances and pharmaceutical agents. Another focus is on antigenic and functional proteins from several pathogenic organisms including the human immunodeficiency virus (HIV) and the widespread parasitic genus, Schistosoma. My efforts this summer have been twofold: first, to identify clinically significant drug interactions involving albumin binding displacement and to initiate studies of the three-dimensional structure of albumin complexed with these agents, and secondly, to establish collaborative efforts to extend the lab's work on human pathogens.

As part of a broader regional effort focused on climate change education and rural communities, this paper focuses on a specific effort to understand effective approaches to two presumably complementary goals: The goal of increasing knowledge about climate change and climate science in a community, and the goal of having communities use climate change and climate science information when making decisions. In this paper, we explore the argument that people do not need or want to know about climate change, in order to make responsible and sustainable energy decisions. Furthermore, we hypothesize that involvement in making responsible and sustainable energy decisions will increase openness and readiness to process climate science information, and thus increase learning about climate change in subsequent exposures to such information. Support for these hypotheses would suggest that rather than encouraging education to enable action (including engagement in attempts to make responsible decisions), efforts should focus on encouraging actions first and education second. To investigate our hypotheses, we will analyze and report results from efforts to engage residents from a medium-sized Midwestern city to give input on future programs involving sustainable energy use. The engagement process (which will not be complete until after the AGU deadline) involves an online survey and an optional face-to-face discussion with city officials and experts in energy-related areas. The online survey includes brief information about current local energy programs, questions assessing knowledge of climate change, and an open-ended question asking what additional information residents need in order to make good decisions and recommendations concerning the energy programs. To examine support for our hypotheses, we will report (1) relationships between subjective and objective knowledge of climate science and willingness to attend the face-to-face discussion about the city's energy decisions and actual attendance at the event, (2) a content analysis of what residents say they want and need to know in order to make decisions and recommendations about the city's energy programs, and (3) pilot results from a comparison of learning from a reading about climate change presented prior to the event, after the event, or presented to those who were willing to attend the face-to-face event but did not attend. We will discuss the results in terms of their implications for the relationship between knowledge and behavior, versus change in knowledge and change in behavior.
Lessons learned from planetary science archiving

The need for scientific archiving of past, current, and future planetary scientific missions, laboratory data, and modeling efforts is indisputable. To quote from a message by G. Santayama carved over the entrance of the US Archive in Washington DC “Those who can not remember the past are doomed to repeat it.” The design, implementation, maintenance, and validation of planetary science archives are however disputed by the involved parties. The inclusion of the archives into the scientific heritage is problematic. For example, there is the imbalance between space agency requirements and institutional and national interests. The disparity of long-term archive requirements and immediate data analysis requests are significant. The discrepancy between the space missions archive budget and the effort required to design and build the data archive is large. An imbalance exists between new instrument development and existing, well-proven archive standards. The authors present their view on the problems and risk areas in the archiving concepts based on their experience acquired within NASA’s Planetary Data System (PDS) and ESA’s Planetary Science Archive (PSA). Individual risks and potential problem areas are discussed based on a model derived from a system analysis done upfront. The major risk for a planetary mission science archive is seen in the combination of minimal involvement by Mission Scientists and inadequate funding. The authors outline how the risks can be reduced. The paper ends with the authors view on future planetary archive implementations including the archive interoperability aspect.

While there has been a growing body of literature on the impact of combat stressors and post-traumatic stress on military service members involved in current conflicts, there has been little available information that directly examines the impact of these on healthcare providers. Aims for this integrative review included: (1) identifying exposures, experiences and other factors influencing stress responses in military healthcare providers previously engaged in a war effort and (2) describing the incidence of post-traumatic stress and related mental health problems in this population. Using Cooper's integrative review method, relevant documents were collected and analysed using content categories and a coding scheme to assist with identifying and recording data for units of analysis. Literature searches (including all years to present) were conducted using keywords for stress reaction, for healthcare provider and for military war effort involvement. Literature was obtained using the Cumulative Index to Nursing and Allied Health Literature, the National Library of Medicine and the American Psychological Association databases. Evidence suggests that similar to military combatants, military healthcare provider exposure to life-threatening situations will increase the probability of adverse psychological disorders following these traumatic experiences. The presence of a strong sense of meaning and purpose, within a supportive environment appear to help mediate the impact of these dangerous and stressful events. Results of this review and other supporting literature indicate the need for a systematic approach to studying combat stress and post-traumatic stress in deployed healthcare providers. © 2011 Blackwell Publishing Ltd.

A number of mutilating procedures, such as dehorning in cattle and goats and beak trimming in laying hens, are common in farm animal husbandry systems in an attempt to prevent or solve problems, such as injuries from horns or feather pecking. These procedures and other practices, such as early maternal separation, overcrowding, and barren housing conditions, raise concerns about animal welfare. Efforts to ensure or improve animal welfare involve adapting the animal to its environment, i.e., by selective breeding (e.g., by selecting "robust" animals) adapting the environment to the animal (e.g., by developing social housing systems in which aggressive encounters are reduced to a minimum), or both. We propose adapting the environment to the animals by improving management practices and housing conditions, and by abandoning mutilating procedures. This approach requires the active involvement of all stakeholders: veterinarians and animal scientists, the industrial farming sector, the food processing and supply chain, and consumers of animal-derived products. Although scientific evidence about the welfare effects of current practices in farming such as mutilating procedures, management practices, and housing conditions is steadily growing, the gain in knowledge needs a boost through more scientific research. Considering the huge number of animals whose welfare is affected, all possible effort must be made to improve their welfare as quickly as possible in order to ban welfare-compromising procedures and practices as soon as possible.
THE ADVERSE OUTCOME PATHWAY (AOP) FRAMEWORK ...
An Adverse Outcome Pathway (AOP) represents the organization of current and newly acquired knowledge of biological pathways. These pathways contain a series of nodes (Key Events, KEs) that when sufficiently altered influence the next node on the pathway, beginning from an Molecular Initiating Event (MIE), through intermediate KEs, ending in an Adverse Outcome (AO) which may be used as a basis for decision making. A KE is a measurable biological change, and is linked with other KEs via Key Event Relationships (KERs). A given KE may be involved in several AOPs, leading to a plausible network of biological changes that are involved in an organism’s response to an external stressor. When describing an AOP, five guiding principles have been proposed [1]: 1) an AOP is not specific to a single external stressor, 2) AOPs are modular, with KEs and KERs that can be used in several AOPs, 3) a single AOP is the unit of development, 4) most biological responses will be the result of networks of AOPs, and 5) AOPs will be modified as more biological knowledge becomes available. The collaborative development of AOPs is recommended to be performed using the AOP-Wiki (https://aopwiki.org), which is an effort between the European Commission – DG Joint Research Centre (JRC) and U.S. Environmental Protection Agency (EPA). The Wiki is one part of a larger OECD-sponsored AOP Knowledgebase effort, which is a repository for all AOPs developed as part of the Organization for Economic

A recent report from the British Nuffield Council on Bioethics associated 'emerging biotechnologies' with a threefold challenge: 1) uncertainty about outcomes, 2) diverse public views on the values and implications attached to biotechnologies and 3) the possibility of creating radical changes regarding societal relations and practices. To address these challenges, leading international institutions stress the need for public involvement activities (PIAs). The objective of this study was to assess the state of PIA reports in the field of biomedical research. PIA reports were identified via a systematic literature search. Thematic text analysis was employed for data extraction. After filtering, 35 public consultation and 11 public participation studies were included in this review. Analysis and synthesis of all 46 PIA studies resulted in 6 distinguishable PIA objectives and 37 corresponding PIA methods. Reports of outcome translation and PIA evaluation were found in 9 and 10 studies respectively (20% and 22%). The paper presents qualitative details. The state of PIAs on biomedical research and innovation is characterized by a broad range of methods and awkward variation in the wording of objectives. Better comparability of PIAs might improve the translation of PIA findings into further policy development. PIA-specific reporting guidelines would help in this regard. The modest level of translation efforts is another pointer to the "deliberation to policy gap". The results of this review could inform the design of new PIAs and future efforts to improve PIA comparability and outcome translation.

Pacific Ocean western boundary currents and the interlinked equatorial Pacific circulation system were among the first currents of these types to be explored by pioneering oceanographers. The widely accepted but poorly quantified importance of these currents-in processes such as the El Niño/Southern Oscillation, the Pacific Decadal Oscillation and the Indonesian Throughflow-has triggered renewed interest. Ongoing efforts are seeking to understand the heat and mass balances of the equatorial Pacific, and possible changes associated with greenhouse-gas-induced climate change. Only a concerted international effort will close the observational, theoretical and technical gaps currently limiting a robust answer to these elusive questions.

Sedimentation has severely impacted backwater lakes along the Illinois River. The State of Illinois and the US Army Corps of Engineers are currently involved in a joint effort to address ecosystem degradation within the Illinois River Basin, and excessive sedimentation of backwater lakes and side channels is a primary cause of that degradation. Necessary parts of the overall restoration effort are to adequately characterize both the quality and quantity of backwater lake sediments prior to implementing any restoration efforts, and to identify potential beneficial reuses of dredged sediments. This paper summarizes some of our efforts in these areas with an emphasis on Peoria Lake which has received the most attention to date. Sediment characterization has included detailed bathymetric surveys, sediment dating with 137 Cs, chemical and mineralogical characterization of sediments to three meters depth, analysis of recent sediments (to 30 cm depth) for acid-volatile sulfide and simultaneously extracted metals, and analysis of ammonia and toxic metals in sediment pore waters. Dredged sediments have also been used in various trial projects to demonstrate potential handling and beneficial reuse strategies. Some significant findings of these studies are: 1) Long-term sedimentation rates are high, and average 1–3 cm y −1 ; 2) total concentrations of several trace metals (e.g., Pb, Cd, Ni) and PAH compounds sometimes exceed consensus-based probable effect levels for sensitive sediment-dwelling organisms; 3) pore water dissolved ammonia concentrations in Peoria Lake are potentially toxic to sensitive sediment-dwelling species; and 4) weathered sediments can make productive agricultural soils.

Emerging career pathways for graduate students in earth, ocean and climate sciences increasingly require skills in teaching and communication. This is true of academic careers, in which demonstrated teaching skills make applicants for faculty positions far more competitive, and traditionally less conventional careers outside of academia that require cross-disciplinary collaboration and/or communication to audiences not directly involved in science research (e.g. policy makers, educators, the public). Yet most graduate education programs provide little to no opportunity or incentive for young investigators to develop and hone these skills, and graduate students are often discouraged from deviating from the traditional "research apprenticeship" model during their graduate education. At Scripps, the Birch Aquarium at Scripps, and UC San Diego Extension, we are developing new ways to integrate teaching, communication, and outreach into our graduate education program, thus broadening the scope of graduate training and better serving the needs and evolving career aspirations of our graduate students. This effort is an integral part of our overall outreach strategy a Scripps in which we seek to combine high quality STEM outreach and teaching with opportunities for Scripps graduate students to put their teaching and communications training into practice. The overall effort is a "win-win" both for our students and for the highly diverse K-16 community in San Diego County. In this talk we will summarize the programmatic efforts currently underway at Scripps, our strategic collaboration with UCSD Extension, which is expanding the capacity and reach of our integrated program, and our plans for sustaining these efforts for the long term.
Advancing efforts to address youth violence involvement.
Weist, M D; Cooley-Quille, M
2001-06-01
Discusses the increased public attention on violence-related problems among youth and the concomitant increased diversity in research. Youth violence involvement is a complex construct that includes violence experienced in multiple settings (home, school, neighborhood) and in multiple forms (as victims, witnesses, perpetrators, and through family members, friends, and the media). Potential impacts of such violence involvement are considerable, including increased internalizing and externalizing behaviors among youth and future problems in school adjustment and life-course development. This introductory article reviews key dimensions of youth-related violence, describes an American Psychological Association Task Force (Division 12) developed to advance relevant research, and presents examples of national resources and efforts that attempt to address this critical public health issue.
Parental spanking of 1-year-old children and subsequent child protective services involvement✩
Lee, Shawna J.; Grogan-Kaylor, Andrew; Berger, Lawrence M.
2015-01-01
The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], p<.01). When compared to non-spanked children, there was a 33% greater probability of subsequent CPS involvement for children who were spanked at age 1. Given the undesirable consequences of spanking children and a lack of empirical evidence to suggest positive effects of physical punishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life. PMID:24602690
Design Considerations For Imaging Charge-Coupled Device (ICCD) Star Sensors
NASA Astrophysics Data System (ADS)
McAloon, K. J.
1981-04-01
A development program is currently underway to produce a precision star sensor using imaging charge coupled device (ICCD) technology. The effort is the critical component development phase for the Air Force Multi-Mission Attitude Determination and Autonomous Navigation System (MADAN). A number of unique considerations have evolved in designing an arcsecond accuracy sensor around an ICCD detector. Three tiers of performance criteria are involved: at the spacecraft attitude determination system level, at the star sensor level, and at the detector level. Optimum attitude determination system performance involves a tradeoff between Kalman filter iteration time and sensor ICCD integration time. The ICCD star sensor lends itself to the use of a new approach in the functional interface between the attitude determination system and the sensor. At the sensor level image data processing tradeoffs are important for optimum sensor performance. These tradeoffs involve the sensor optic configuration, the optical point spread function (PSF) size and shape, the PSF position locator, and the microprocessor locator algorithm. Performance modelling of the sensor mandates the use of computer simulation programs. Five key performance parameters at the ICCD detector level are defined. ICCD error characteristics have also been isolated to five key parameters.
Interwoven support: an historical survey of US federal programs enabling immunization.
Dalrymple, Dack W; Grabenstein, John D
2014-11-28
The US Government (USG) can date its involvement with immunization to military and civilian efforts in 1777 and 1813 to prevent smallpox. USG involvement began accelerating with federal licensing of vaccine and antibody manufacturers in 1903. In addition to ongoing regulation of manufacturing and product quality, military and civilian arms of the USG have led research efforts into new or improved vaccines. These efforts have included diseases endemic in the United States, as well as medical countermeasures targeted against biological weapons, influenza pandemics, and emerging infectious diseases. Especially since the 1950s, the USG has provided increasing levels of funding to purchase vaccines and conduct vaccination programs. These programs have focused largely on children, although vaccination programs for adults have been expanded somewhat in recent years. Multiple agencies of the USG have convened various panels of accomplished external experts who have generated widely regarded recommendations on vaccine safety and efficacy and optimal immunization practices. USG programs for safety assessment, injury compensation, liability protection, and disease surveillance have been developed to assess needs, evaluate safety questions, ensure vaccine supply, and foster confidence in vaccination efforts. Debates on the extent of government involvement date back to the 1890 s and continue today. Several pivotal expansions of government involvement followed disease outbreaks or manufacturing accidents. This historical survey describes each of the major US federal programs in these categories, including references to applicable law. Copyright © 2014 Elsevier Ltd. All rights reserved.

Healthcare reform as part of the economic recovery plan in Japan is placing emphasis on the use of healthcare information technology (HIT). This research mainly focuses on the HIT efforts in Japan with reference to the US for context. The purpose is to: (a) provide detail on governmental policy impacting promotion of HIT adoption to provide services to the people of Japan, (b) describe the outcomes of past and present policy impacting progress based on a case study of HIT use in the Kyoto Yamashina area, and (c) discuss issues for refinement of current policy. The method is case study, and data collection techniques include: (a) interviews of people involved in policy making for HIT in Japan (Japanese healthcare professionals, government officials, and academics involved in HIT research in Japan) and use in the medical community of HIT in the Kyoto Yamashina area, (b) archived document analysis of reports regarding government policy for HIT policy and user assessment for HIT mainly in the case study site, and (c) the literature review about HIT progression and effectiveness assessments to explore and describe issues concerning the transformation with HIT in Japan. This study reveals the aspects of governmental policy that have been effective in promoting successful HIT initiatives as well as some that have been detriments in Japan to help solve pressing social issues regarding healthcare delivery. For example, Japan has stipulated some standardized protocols and formats for HIT but does not mandate exactly how to engage in inter-organizational or intra-organizational health information exchange. This provides some desired autonomy for healthcare organizations and or governments in medical communities and allows for more advanced organizations to leverage current resources while providing a basis for lesser equipped organizations to use in planning the initiative. The insights gained from the Kyoto Yamashina area initiative reflect the success of past governmental policy efforts and the current intent to promote HIT adoption. Insights from the case study as well as other social issues facing Japan warrant some refinement of policy. The refinement concerns: (a) the necessity for leadership and IT knowledge in the medical communities, (b) provider incentives, (c) legislation regarding accountability, security, privacy and confidentiality, (d) inclusion of stakeholders in solution development, and (e) creating sustainable business models. The research highlights the efforts of Japan for using HIT in healthcare reform. We present outcomes from a case study of the Kyoto Yamashina area medical community as proof of concept for past and present policy in Japan that are insightful for proliferation of successful projects in Japan and adoption of HIT in general.

Reducing water scarcity possible by 2050: Linking global assessments to policy dimensions
NASA Astrophysics Data System (ADS)
Wada, Y.; Gleeson, T.; Esnault, L.
2015-12-01
Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries in 2016. Irrigation techniques, industrial and residential habits combined with climate change lie at the root of the problem. But despite what appears to be an insurmountable problem, it is possible to turn the situation around and significantly reduce water scarcity in over next 35 years. We identify outline strategies in six key areas that they believe can be combined in different ways in different parts of the world in order to effectively reduce water stress. (Water stress occurs in an area where more than 40% of the available water from rivers is unavailable because it is already being used - a situation that currently affects about a third of the global population, and may affect as many as half the people in the world by the end of the century if the current pattern of water use continues). We separate six key strategy areas for reducing water stress into "hard path" measures, involving building more reservoirs and increasing desalination efforts of sea water, and "soft path" measures that focus on reducing water demand rather than increasing water supply thanks to community-scale efforts and decision-making, combining efficient technology and environmental protection. While there are some economic, cultural and social factors that may make certain of the "soft path" measures such as population control difficult, the "soft path" measures offer the more realistic path forward in terms of reducing water stress by 2050.
Calcium intake trends and health consequences from childhood through adulthood.
Nicklas, Theresa A
2003-10-01
Issues involving low calcium intake and dairy product consumption are currently the focus of much debate and discussion at both the scientific and lay community levels. In this review, we examine the following major areas of interest: (1). the role of calcium intake and dairy product consumption in chronic diseases, (2). nutritional qualities of milk and other dairy products, (3). trends in calcium intake and dairy product consumption, (4). current status of calcium intakes and dairy product consumption in children, (5). tracking of calcium intake and diary product consumption, (6). the impact of school meal participation on calcium intake and dairy product consumption, (7). concerns related to calcium-fortified foods and beverages and (8). factors influencing children's milk consumption. To date, the findings indicate that calcium intake and dairy product consumption have beneficial roles in a variety of chronic diseases; dairy products provide an abundant source of vitamins and minerals; calcium intakes of children have increased over time, yet intakes are not meeting the current adequate intake (AI) calcium recommendations; dairy consumption has decreased, and soft drink consumption and, possibly, consumption of calcium-fortified products have increased; consumption of dairy products have a positive nutritional impact on diets of children, particularly from school meals, and there are many factors which influence children's milk consumption, all of which need to be considered in our efforts to promote adequate calcium intakes by children. Based on this review, areas that need immediate attention and future research imperatives are summarized in an effort to further our understanding on what we already know and what we need to know to promote healthier eating habits early in life.

The aim of this study was to examine what factors affect the acceptance behavior and use of new technologies for rehabilitation by therapists at a large rehabilitation hospital in Canada. A self-administrated paper-based survey was created by adapting scales with high levels of internal consistency in prior research using the Unified Theory of Acceptance and Use of Technology (UTAUT). Items were scored on a 7-point Likert scale, ranging from "strongly disagree (1)" to "strongly agree (7)". The target population was all occupational therapists (OT) and physical therapists (PT) involved with the provision of therapeutic interventions at the hospital. Our research model was tested using partial least squares (PLS) technique. Performance expectancy was the strongest salient construct for behavioral intention to use new technologies in rehabilitation, whereas neither effort expectancy nor social influence were salient constructs for behavioral intention to use new technologies; (4) facilitating condition and behavioral intention to use new technologies were salient constructs for current use of new technologies in rehabilitation, with facilitating condition the strongest salient for current use of new technologies in rehabilitation. In a large rehabilitation hospital where use of new technologies in rehabilitation is not mandatory, performance expectancy, or how the technology can help in therapists' work, was the most important factor in determining therapists' acceptance and use of technologies. However, effort expectancy and social influence constructs were not important, i.e. therapists were not influenced by the degree of difficulty or social pressures to use technologies. Behavioral intention and facilitating condition, or institutional support, are related to current use of new technologies in rehabilitation.

A loss of sensory hair cells or spiral ganglion neurons from the inner ear causes deafness, affecting millions of people. Currently, there is no effective therapy to repair the inner ear sensory structures in humans. Cochlear implantation can restore input, but only if auditory neurons remain intact. Efforts to develop stem cell-based treatments for deafness have demonstrated progress, most notably utilizing embryonic-derived cells. In an effort to bypass limitations of embryonic or induced pluripotent stem cells that may impede the translation to clinical applications, we sought to utilize an alternative cell source. Here, we show that adult human mesenchymal-like stem cells (MSCs) obtained from nasal tissue can repair spiral ganglion loss in experimentally lesioned cochlear cultures from neonatal rats. Stem cells engraft into gentamicin-lesioned organotypic cultures and orchestrate the restoration of the spiral ganglion neuronal population, involving both direct neuronal differentiation and secondary effects on endogenous cells. As a physiologic assay, nasal MSC-derived cells engrafted into lesioned spiral ganglia demonstrate responses to infrared laser stimulus that are consistent with those typical of excitable cells. The addition of a pharmacologic activator of the canonical Wnt/β-catenin pathway concurrent with stem cell treatment promoted robust neuronal differentiation. The availability of an effective adult autologous cell source for inner ear tissue repair should contribute to efforts to translate cell-based strategies to the clinic. PMID:24172073

Over the next few years, an increasing number of entities ranging from international, national, and regional governments, to businesses and private land-owners, are likely to become more involved in efforts to limit atmospheric concentrations of greenhouse gases. In such a world, geospatially resolved information about the location, amount, and rate of greenhouse gas (GHG) emissions will be needed, as well as the stocks and flows of all forms of carbon through the earth system. The ability to implement policies that limit GHG concentrations would be enhanced by a global, open, and transparent greenhouse gas information system (GHGIS). An operational and scientifically robust GHGIS would combine ground-based and space-based observations, carbon-cycle modeling, GHG inventories, synthesis analysis, and an extensive data integration and distribution system, to provide information about anthropogenic and natural sources, sinks, and fluxes of greenhouse gases at temporal and spatial scales relevant to decision making. The GHGIS effort was initiated in 2008 as a grassroots inter-agency collaboration intended to identify the needs for such a system, assess the capabilities of current assets, and suggest priorities for future research and development. We will present a vision for an open, global GHGIS including latest analysis of system requirements, critical gaps, and relationship to related efforts at various agencies, the Group on Earth Observations, and the Intergovernmental Panel on Climate Change.

The majority of quality measures used to assess providers and hospitals are based on easily obtained data, focused on a few dimensions of quality, and developed mainly for primary/community care and population health. While this approach supports efforts focused on addressing the triple aim of health care, many current quality report cards and assessments do not reflect the breadth or complexity of many referral center practices. In this article, the authors highlight the differences between population health efforts and referral care and address issues related to value measurement and performance assessment. They discuss why measures may need to differ across the three levels of care (primary/community care, secondary care, complex care) and illustrate the need for further risk adjustment to eliminate referral bias. With continued movement toward value-based purchasing, performance measures and reimbursement schemes need to reflect the increased level of intensity required to provide complex care. The authors propose a framework to operationalize value measurement and payment for specialty care, and they make specific recommendations to improve performance measurement for complex patients. Implementing such a framework to differentiate performance measures by level of care involves coordinated efforts to change both policy and operational platforms. An essential component of this framework is a new model that defines the characteristics of patients who require complex care and standardizes metrics that incorporate those definitions.

Over the next few years, an increasing number of entities ranging from international, national, and regional governments, to businesses and private land-owners, are likely to become more involved in efforts to limit atmospheric concentrations of greenhouse gases. In such a world, geospatially resolved information about the location, amount, and rate of greenhouse gas (GHG) emissions will be needed, as well as the stocks and flows of all forms of carbon through terrestrial ecosystems and in the oceans. The ability to implement policies that limit GHG concentrations would be enhanced by a global, open, and transparent greenhouse gas information system (GHGIS). An operational and scientifically robust GHGIS would combine ground-based and space-based observations, carbon-cycle modeling, GHG inventories, meta-analysis, and an extensive data integration and distribution system, to provide information about sources, sinks, and fluxes of greenhouse gases at policy-relevant temporal and spatial scales. The GHGIS effort was initiated in 2008 as a grassroots inter-agency collaboration intended to rigorously identify the needs for such a system, assess the capabilities of current assets, and suggest priorities for future research and development. We will present a status of the GHGIS effort including our latest analysis and ideas for potential near-term pilot projects with potential relevance to European initiatives including the Global Monitoring for Environment and Security (GMES) and the Integrated Carbon Observing System (ICOS).
Evaluating the Usefulness of High-Temporal Resolution Vegetation Indices to Identify Crop Types

2006-12-01
The National Aeronautical and Space Agency (NASA) and the United States Department of Agriculture (USDA) jointly sponsored research covering the 2004 to 2006 South American crop seasons that focused on developing methods for the USDA's Foreign Agricultural Service's (FAS) Production Estimates and Crop Assessment Division (PECAD) to identify crop types using MODIS-derived, hyper-temporal Normalized Difference Vegetation Index (NDVI) images. NDVI images were composited in 8 day intervals from daily NDVI images and aggregated to create a hyper-termporal NDVI layerstack. This NDVI layerstack was used as input to image classification algorithms. Research results indicated that creating high-temporal resolution Normalized Difference Vegetation Index (NDVI) composites from NASA's MODerate Resolution Imaging Spectroradiometer (MODIS) data products provides useful input to crop type classifications as well as potential useful input for regional crop productivity modeling efforts. A current NASA-sponsored Rapid Prototyping Capability (RPC) experiment will assess the utility of simulated future Visible Infrared Imager / Radiometer Suite (VIIRS) imagery for conducting NDVI-derived land cover and specific crop type classifications. In the experiment, methods will be considered to refine current MODIS data streams, reduce the noise content of the MODIS, and utilize the MODIS data as an input to the VIIRS simulation process. The effort also is being conducted in concert with an ISS project that will further evaluate, verify and validate the usefulness of specific data products to provide remote sensing-derived input for the Sinclair Model a semi-mechanistic model for estimating crop yield. The study area encompasses a large portion of the Pampas region of Argentina--a major world producer of crops such as corn, soybeans, and wheat which makes it a competitor to the US. ITD partnered with researchers at the Center for Surveying Agricultural and Natural Resources (CREAN) of the National University of Cordoba, Argentina, and CREAN personnel collected and continue to collect field-level, GIS-based in situ information. Current efforts involve both developing and optimizing software tools for the necessary data processing. The software includes the Time Series Product Tool (TSPT), Leica's ERDAS Imagine, and Mississippi State University's Temporal Map Algebra computational tools.
The Challenge and Opportunity of Parental Involvement in Juvenile Justice Services.

2014-04-01
The active involvement of parents - whether as recipients, extenders, or managers of services - during their youth's experience with the juvenile justice system is widely assumed to be crucial. Parents and family advocacy groups note persisting concerns with the degree to which successful parental involvement is achieved. Justice system providers are highly motivated and actively working to make improvements. These coalescing interests provide a strong motivation for innovation and improvement regarding family involvement, but the likely success of these efforts is severely limited by the absence of any detailed definition of parental involvement or validated measure of this construct. Determining whether and how parental involvement works in juvenile justice services depends on the development of clear models and sound measurement. Efforts in other child serving systems offer guidance to achieve this goal. A multidimensional working model developed with parents involved in child protective services is presented as a template for developing a model for parental involvement in juvenile justice. Features of the model requiring changes to make it more adaptable to juvenile justice are identified. A systematic research agenda for developing methods and measures to meet the present demands for enhanced parental involvement in juvenile justice services is presented.

Efforts to promote the development of pediatric pharmacotherapy include regulatory frameworks and close collaboration between the US Food and Drug Administration and the European Medicines Agency. We characterized the current status of pediatric clinical trials conducted in the United States by the pharmaceutical industry, focusing on the involvement of the European Union member countries, to clarify the industry perspective. Data on US pediatric clinical trials were obtained from ClinicalTrials.gov . Binary regression analysis was performed to identify what factors influence the likelihood of involvement of European Union countries. A total of 633 US pediatric clinical trials that met inclusion criteria were extracted and surveyed. Of these, 206 (32.5%) involved a European Union country site(s). The results of binary regression analysis indicated that attribution of industry, phase, disease area, and age of pediatric participants influenced the likelihood of the involvement of European Union countries in US pediatric clinical trials. Relatively complicated or large pediatric clinical trials, such as phase II and III trials and those that included a broad age range of participants, had a significantly greater likelihood of the involvement of European Union countries ( P < .05). Our results suggest that (1) the pharmaceutical industry utilizes regulatory frameworks in making business decisions regarding pediatric clinical trials, (2) disease area affects the involvement of European Union countries, and (3) feasibility of clinical trials is mainly concerned by pharmaceutical industry for pediatric drug development. Additional incentives for high marketability may further motivate pharmaceutical industry to develop pediatric drugs.

The second Python in Astronomy conference will be held from 21-25 March 2016 at the University of Washington eScience Institute in Seattle, WA, USA. Similarly to the 2015 meeting (which was held at the Lorentz Center), we are aiming to bring together researchers, Python developers, users, and educators. The conference will include presentations, tutorials, unconference sessions, and coding sprints. In addition to sharing information about state-of-the art Python Astronomy packages, the workshop will focus on improving interoperability between astronomical Python packages, providing training for new open-source contributors, and developing educational materials for Python in Astronomy. The meeting is therefore not only aimed at current developers, but also users and educators who are interested in being involved in these efforts.

The quest for a cure for HIV remains a timely and key challenge for the HIV research community. Despite significant scientific advances, current HIV therapy regimens do not completely eliminate the negative impact of HIV on the immune system; and the economic impact of treating all people infected with HIV globally, for the duration of their lifetimes, presents significant challenges. This article discusses, from a multi-disciplinary approach, critical social, behavioral, ethical, and economic issues permeating the HIV cure research agenda. As part of a search for an HIV cure, both the perspective of patients/participants and clinical researchers should be taken into account. In addition, continued efforts should be made to involve and educate the broader community. PMID:26642901
Unmasking molecular profiles of bladder cancer.
Piao, Xuan-Mei; Byun, Young Joon; Kim, Wun-Jae; Kim, Jayoung
2018-03-01
Precision medicine is designed to tailor treatments for individual patients by factoring in each person's specific biology and mechanism of disease. This paradigm shifted from a "one size fits all" approach to "personalized and precision care" requires multiple layers of molecular profiling of biomarkers for accurate diagnosis and prediction of treatment responses. Intensive studies are also being performed to understand the complex and dynamic molecular profiles of bladder cancer. These efforts involve looking bladder cancer mechanism at the multiple levels of the genome, epigenome, transcriptome, proteome, lipidome, metabolome etc. The aim of this short review is to outline the current technologies being used to investigate molecular profiles and discuss biomarker candidates that have been investigated as possible diagnostic and prognostic indicators of bladder cancer.

This task involves development and characterization of selective laser melting (SLM) parameters for additive manufacturing of titanium-6%aluminum-4%vanadium (Ti-6Al-4V or Ti64). SLM is a relatively new manufacturing technology that fabricates complex metal components by fusing thin layers of powder with a high-powered laser beam, utilizing a 3D computer design to direct the energy and form the shape without traditional tools, dies, or molds. There are several metal SLM technologies and materials on the market today, and various efforts to quantify the mechanical properties, however, nothing consolidated or formal to date. Meanwhile, SLM material fatigue properties of Ti64 are currently highly sought after by NASA propulsion designers for rotating turbomachinery components.

The last 40 years of literature pertaining to sexuality and deaf individuals are reviewed. Current research, which establishes that people who are deaf do not have adequate information on sexuality issues, is examined, as well as some of the factors that play a role in the ineffective dissemination of sexuality information to this population. Parents, education (both in a historical and a contemporary light), peers, and the very acquisition of language are examined with regard to their contextualized part in the process of knowledge sharing. Historical paradigms are placed within Griffiths's "mythconceptions" framework (as discussed in Watson, 2002) in an effort to determine possible causative factors relating to deaf people's insufficient knowledge regarding sexuality.

The purpose of this study was to examine the language teachers used to discuss inclusion, Universal Design for Learning (UDL), and learners with intellectual disability (ID) in an effort to better understand how teachers describe the relationship between those three. Utilizing a secondary analysis procedure, interview transcripts from seven general education teachers were reanalyzed to identify language used by teachers to refer to inclusive educational settings, the implementation of UDL, and learners with intellectual disability. The identified themes were then juxtaposed against the UDL framework (principles, guidelines, and checkpoints) and the current literature related to UDL and inclusive education. We end with recommendations for future practice and research involving inclusive classrooms, UDL, and learners with ID.

Ethical issues in research with children and young people.
Matutina, Robin E
2009-10-01
This article, which concentrates largely on literature from the United States, discusses the ethical aspects of research with children, beginning with the historical ill-treatment of children and extending to the present-day protections. Researchers struggle to find the balance that would most benefit this vulnerable population. Children must be protected but society deserves the knowledge that can only be gained through child-specific research. Ethical questions arise through the presentation of historical and current cases of children involved in or excluded from research. Examples of ethical dilemmas are presented in an effort to allow the reader to learn from the past while seeking to provide research-based care today. Strategies are included to help safeguard the autonomy of the child who participates in research.
The potential impact of bone tissue engineering in the clinic
Mishra, Ruchi; Bishop, Tyler; Valerio, Ian L; Fisher, John P; Dean, David
2016-01-01
Bone tissue engineering (BTE) intends to restore structural support for movement and mineral homeostasis, and assist in hematopoiesis and the protective functions of bone in traumatic, degenerative, cancer, or congenital malformation. While much effort has been put into BTE, very little of this research has been translated to the clinic. In this review, we discuss current regenerative medicine and restorative strategies that utilize tissue engineering approaches to address bone defects within a clinical setting. These approaches involve the primary components of tissue engineering: cells, growth factors and biomaterials discussed briefly in light of their clinical relevance. This review also presents upcoming advanced approaches for BTE applications and suggests a probable workpath for translation from the laboratory to the clinic. PMID:27549369

Alfred Russel Wallace's world of final causes.
Smith, Charles H
2013-12-01
Alfred Russel Wallace (1823-1913) is an important figure in the history of science, but there remain many questions about the nature of his world view, and how it developed. Here, Wallace's appreciation of the role of final causes in evolution is linked to some of its probable origins, with an emphasis on the influence of Alexander von Humboldt (1769-1859). The question is then asked whether a final causes-based scientific agenda might be possible, and answered by drawing attention to two current efforts in that direction by Adrian Bejan, and by the author. A sketch of the latter approach, adapted from Spinozian thinking, is given, with an empirical example involving drainage basin morphology that suggests structural influences of a final causes sort.
Study on needs for a magnetic suspension system operating with a transonic wind tunnel

Martindale, W. R.; Butler, R. W.; Starr, R. F.
1985-01-01
The U.S. aeronautical industry was surveyed to determine if current and future transonic testing requirements are sufficient to justify continued development work on magnetic suspension and balance systems (MSBS) by NASA. The effort involved preparation of a brief technical description of magnetic suspension and balance systems, design of a survey form asking specific questions about the role of the MSBS in satisfying future testing requirements, selecting nine major aeronautics companies to which the description and survey forms were sent, and visiting the companies and discussing the survey to obtain greater insight to their response to the survey. Evaluation and documentation of the survey responses and recommendations which evolved from the study are presented.
Assessment of the Free-piston Stirling Convertor as a Long Life Power Convertor for Space
NASA Technical Reports Server (NTRS)
Schreiber, Jeffrey G.
2001-01-01
There is currently a renewed interest in the use of free-piston Stirling power convertors for space power applications. More specifically, the Stirling convertor is being developed to be part of the Stirling Radioisotope Power System to supply electric power to spacecraft for NASA deep space science missions. The current development effort involves the Department of Energy, Germantown, MD, the NASA Glenn Research Center, Cleveland, OH, and the Stirling Technology Company, Kennewick, WA. The Stirling convertor will absorb heat supplied from the decay of plutonium dioxide contained in the General Purpose Heat Source modules and convert it into electricity to power the spacecraft. For many years the "potentials" of the free-piston Stirling convertor have been publicized by it's developers. Among these "potentials" were long life and high reliability. This paper will present an overview of the critical areas that enable long life of the free-piston Stirling power convertor, and present some of the techniques that have been used when long life has been achieved.

Oreilly, D.
1992-01-01
This task specified developing the hardware and software necessary to implement the System for Anomaly and Failure Detection (SAFD) algorithm, developed under Technology Test Bed (TTB) Task 21, on the TTB engine stand. This effort involved building two units; one unit to be installed in the Block II Space Shuttle Main Engine (SSME) Hardware Simulation Lab (HSL) at Marshall Space Flight Center (MSFC), and one unit to be installed at the TTB engine stand. Rocketdyne personnel from the HSL performed the task. The SAFD algorithm was developed as an improvement over the current redline system used in the Space Shuttle Main Engine Controller (SSMEC). Simulation tests and execution against previous hot fire tests demonstrated that the SAFD algorithm can detect engine failure as much as tens of seconds before the redline system recognized the failure. Although the current algorithm only operates during steady state conditions (engine not throttling), work is underway to expand the algorithm to work during transient condition.
STATs in NK-Cells: The Good, the Bad, and the Ugly.
Gotthardt, Dagmar; Sexl, Veronika
2016-01-01
Natural killer (NK)-cells are major players in the fight against viral infections and transformed cells, but there is increasing evidence attributing a disease-promoting role to NK-cells. Cytokines present in the tumor microenvironment shape NK-cell maturation, function, and effector responses. Many cytokines signal via the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway that is also frequently altered and constitutively active in a broad range of tumor cells. As a consequence, there are currently major efforts to develop therapeutic strategies to target this pathway. Therefore, it is of utmost importance to understand the role and contributions of JAK-STAT molecules in NK-cell biology-only this knowledge will allow us to predict effects of JAK-STAT inhibition for NK-cell functions and to successfully apply precision medicine. We will review the current knowledge on the role of JAK-STAT signaling for NK-cell functions and discuss conditions involved in the switch from NK-cell tumor surveillance to disease promotion.
Current perspectives: the impact of cyberbullying on adolescent health
Nixon, Charisse L
2014-01-01
Cyberbullying has become an international public health concern among adolescents, and as such, it deserves further study. This paper reviews the current literature related to the effects of cyberbullying on adolescent health across multiple studies worldwide and provides directions for future research. A review of the evidence suggests that cyberbullying poses a threat to adolescents’ health and well-being. A plethora of correlational studies have demonstrated a cogent relationship between adolescents’ involvement in cyberbullying and negative health indices. Adolescents who are targeted via cyberbullying report increased depressive affect, anxiety, loneliness, suicidal behavior, and somatic symptoms. Perpetrators of cyberbullying are more likely to report increased substance use, aggression, and delinquent behaviors. Mediating/moderating processes have been found to influence the relationship between cyberbullying and adolescent health. More longitudinal work is needed to increase our understanding of the effects of cyberbullying on adolescent health over time. Prevention and intervention efforts related to reducing cyberbullying and its associated harms are discussed. PMID:25177157
Using emulsion inversion in industrial processes.
Salager, Jean-Louis; Forgiarini, Ana; Márquez, Laura; Peña, Alejandro; Pizzino, Aldo; Rodriguez, María P; Rondón-González, Marianna
2004-05-20
Emulsion inversion is a complex phenomenon, often perceived as an instability that is essentially uncontrollable, although many industrial processes make use of it. A research effort that started 2 decades ago has provided the two-dimensional and three-dimensional description, the categorization and the theoretical interpretation of the different kinds of emulsion inversion. A clear-cut phenomenological approach is currently available for understanding its characteristics, the factors that influence it and control it, the importance of fine-tuning the emulsification protocol, and the crucial occurrence of organized structures such as liquid crystals or multiple emulsions. The current know-how is used to analyze some industrial processes involving emulsion inversion, e.g. the attainment of a fine nutrient or cosmetic emulsion by temperature or formulation-induced transitional inversion, the preparation of a silicone oil emulsion by catastrophic phase inversion, the manufacture of a viscous polymer latex by combined inversion and the spontaneous but enigmatic inversion of emulsions used in metal working operations such as lathing or lamination.
Barriers of Developing Medical Tourism in a Destination: A Case of South Korea.

This study aimed to determine the efficient factors that potentially lead to the barriers of developing medical tourism in South Korea. To explore the current medical tourism trend, a qualitative procedure was adopted. Besides analyzing the current situation of medical tourism in Korea through a systematic searching on the available information and publications, in-depth-interviews were conducted to collect data from relevant authorities and representatives of medical tourism associations in this country. The result revealed, although government have supported this industry, that lack of specialty and expertise among the health care practitioners in the scope of cross cultural communication, seems to be the core barrier to development of medical tourism in Korea. Demands for convenient promotional activities, policy making and action regulation are the other effective factors. Several strategies are required in order to address and combat these barriers, such as governmental support for cultural training, cooperative efforts to encourage health practitioners involved to enhance their cultural and linguistic competence in international scale.

Evaluation of Computer Aided Vortex Forecast System

Rossow, Vernon J.; Olson, Lawrence E. (Technical Monitor)
1995-01-01
Several countries, including the United States. Canada, Germany, England and Russia, are in the process of trying to develop some sort of computer-aided system that will guide controllers at airports on the hazard posed by lift-generated vortices that trail behind subsonic transport aircraft. The emphasis on this particular subject has come about because the hazard posed by wake vortices is currently the only reason why aircraft are spaced at 3 to 6 miles apart during landing and takeoff rather than something like 2 miles. It is well known that under certain weather conditions, aircraft spacings can be safely reduced to as little as the desired 2 miles. In an effort to perhaps capitalize on such a possibility, a combined FAA and NASA program is currently underway in the United States to develop such a system. Needless to say, the problems associated with anticipating the required separation distances when weather conditions are involved is very difficult. Similarly, Canada has a corresponding program to develop a vortex forecast system of their own.

Impairments in willingness to exert effort contribute to the motivational deficits characteristic of the negative symptoms of schizophrenia. The current study evaluated the psychometric properties of 5 new or adapted paradigms to determine their suitability for use in clinical trials of schizophrenia. This study included 94 clinically stable participants with schizophrenia and 40 healthy controls. The effort-based decision-making battery was administered twice to the schizophrenia group (baseline, 4-week retest) and once to the control group. The 5 paradigms included 1 that assesses cognitive effort, 1 perceptual effort, and 3 that assess physical effort. Each paradigm was evaluated on (1) patient vs healthy control group differences, (2) test-retest reliability, (3) utility as a repeated measure (ie, practice effects), and (4) tolerability. The 5 paradigms showed varying psychometric strengths and weaknesses. The Effort Expenditure for Rewards Task showed the best reliability and utility as a repeated measure, while the Grip Effort Task had significant patient-control group differences, and superior tolerability and administration duration. The other paradigms showed weaker psychometric characteristics in their current forms. These findings highlight challenges in adapting effort and motivation paradigms for use in clinical trials.

The purpose of the research was to examine the feasibility and acceptability of a father-based sexual and reproductive health intervention designed to reduce sexual and reproductive (SRH) disparities and increase correct and consistent condom use among Latino adolescent males. The current study conducted in-depth semi-structured interviews with Latino father-son dyads (N=30) designed to elicit perspectives on communication regarding sex and condom use. In addition, the interview protocol included father-son preferences regarding paternal involvement in condom instruction and perceived obstacles and advantages of father direct involvement in education efforts designed to increase correct and consistent condom use among their adolescent sons. Three independent coders conducted both vertical and horizontal analyses of the data to identify emergent themes and reach theoretical saturation. The main findings from this study suggest that Latino fathers can be impactful in shaping Latino adolescent male sexual decision-making and correct and consistent condom use. However, our data highlight that while both feasible and acceptable, Latino fathers identify needing additional support in how best to communicate and seek opportunities to master their own knowledge and skills regarding condom use and effective communication with their adolescent sons about sex. Latino father-based interventions represent an acceptable and feasible option for building upon the recent success of U.S. national efforts to reduce teen pregnancy rates and STI disparities among Latino youth. However, there exists a need for father-based programs that will support Latino fathers in best educating their sons about condom use and better addressing their SRH. Ongoing national efforts to reduce Latino teen SRH disparities warrant the consideration of father-son interventions for Latino adolescent males in the United States. Copyright © 2018.

Efforts in developing a synthetic environment for testing LADAR sensors in a hardware-in-the-loop simulation are continuing at the Aviation and Missile Research, Engineering, and Development Center (AMRDEC) of the U.S. Army Research, Engineering and Development Command (RDECOM). Current activities have concentrated on developing the optical projection hardware portion of the synthetic environment. These activities range from system level design down to component level testing. Of particular interest have been schemes for generating the optical signals representing the individual pixels of the projection. Several approaches have been investigated and tested with emphasis on operating wavelength, intensity dynamic range and uniformity, and flexibility in pixel waveform generation. This paper will discuss some of the results from these current efforts at RDECOM's Advanced Simulation Center (ASC).
Understanding and preventing military suicide.

2012-01-01
The continual rise in the U.S. military's suicide rate since 2004 is one of the most vexing issues currently facing military leaders, mental health professionals, and suicide experts. Despite considerable efforts to address this problem, however, suicide rates have not decreased. The authors consider possible reasons for this frustrating reality, and question common assumptions and approaches to military suicide prevention. They further argue that suicide prevention efforts that more explicitly embrace the military culture and implement evidence-based strategies across the full spectrum of prevention and treatment could improve success. Several recommendations for augmenting current efforts to prevent military suicide are proposed.

In this paper, the development of a three-dimensional (3D) lithium titanium oxide (LTO) pouch cell is presented to first better comprehend its thermal behavior within electrified vehicle applications, but also to propose a strong modeling base for future thermal management system. Current 3D-thermal models are based on electrochemical reactions which are in need for elaborated meshing effort and long computational time. There lacks a fast electro-thermal model which can capture voltage, current and thermal distribution variation during the whole process. The proposed thermal model is a reduce-effort temperature simulation approach involving a 0D-electrical model accommodating a 3D-thermal model to exclude electrochemical processes. The thermal model is based on heat-transfer theory and its temperature distribution prediction incorporates internal conduction and heat generation effect as well as convection. In addition, experimental tests are conducted to validate the model. Results show that both the heat dissipation rate and surface temperature uniformity data are in agreement with simulation results, which satisfies the application requirements for electrified vehicles. Additionally, a LTO battery pack sizing and modeling is also designed, applied and displays a non-uniformity of the cells under driving operation. Ultimately, the model will serve as a basis for the future development of a thermal strategy for LTO cells that operate in a large temperature range, which is a strong contribution to the existing body of scientific literature.

Umbilical cord blood transplantation from HLA-identical siblings provides good results in children. These results support targeted efforts to bank family cord blood units that can be used for a sibling diagnosed with a disease which can be cured by allogeneic hematopoietic stem cell transplantation or for research that investigates the use of allogeneic or autologous cord blood cells. Over 500 patients transplanted with related cord blood units have been reported to the Eurocord registry with a 4-year overall survival of 91% for patients with non-malignant diseases and 56% for patients with malignant diseases. Main hematologic indications in children are leukemia, hemoglobinopathies or inherited hematologic, immunological or metabolic disorders. However, family-directed cord blood banking is not widely promoted; many cord blood units used in sibling transplantation have been obtained from private banks that do not meet the necessary criteria required to store these units. Marketing by private banks who predominantly store autologous cord blood units has created public confusion. There are very few current validated indications for autologous storage but some new indications might appear in the future. Little effort is devoted to provide unbiased information and to educate the public as to the distinction between the different types of banking, economic models and standards involved in such programs. In order to provide a better service for families in need, directed-family cord blood banking activities should be encouraged and closely monitored with common standards, and better information on current and future indications should be made available.

Background Strategies for successful implementation of hospitalwide glucose control efforts were addressed in a conceptual model for the development and implementation of an institutional inpatient glucose management program. Conceptual Model Components The Glucose Steering Committee incrementally developed and implemented hospitalwide glucose policies, coupled with targeted education and clinical decision support to facilitate policy acceptance and uptake by staff while incorporating process and outcome measures to objectively assess the effectiveness of quality improvement efforts. The model includes four components: (1) engaging staff and hospital executives in the importance of inpatient glycemic management, (2) educating staff involved in the care of patients with diabetes through structured knowledge dissemination, (3) executing evidence-based inpatient glucose management through development of policies and clinical decision aids, and (4) evaluating intervention effectiveness through assessing process measures, intermediary glucometric outcomes, and clinical and economic outcomes. An educational curriculum for nursing, provider, and pharmacist diabetes education programs and current glucometrics were also developed. Outcomes Overall the average patient-day–weighted mean blood glucose (PDWMBG) was below the currently recommended maximum of 180 mg/dL in patients with diabetes and hyperglycemia, with a significant decrease in PDWMBG of 7.8 mg/dL in patients with hyperglycemia. The program resulted in an 18.8% reduction in hypoglycemia event rates, which was sustained. Conclusion Inpatient glucose management remains an important area for patient safety, quality improvement, and clinical research, and the implementation model should guide other hospitals in their glucose management initiatives.

Thermochemical liquifaction processing of biomass to produce bio-derived fuels (e.g. gasoline, jet fuel, diesel, home heating oil, etc.) is of great recent interest as a renewable energy source. Approaches under investigation include direct liquefaction, hydrothermal liquefaction, hydropyrolysis, fast pyrolysis, etc. to produce energy dense liquids that can be utilized as produced or further processed to provide products of higher value. An issue with bio-oils is that they tend to contain significant concentrations of organic compounds, which make the bio-oil acidic and a potential source of corrosion issues in in transport, storage, and use. Efforts devoted to modified/further processing of bio-oilsmore » to make them less corrosive are currently being widely pursued. Another aspect that must also be addressed is potential corrosion issues in the bio-oil liquefaction process equipment itself. Depending on the specific process, bio-oil liquefaction production temperatures can reach up to 400-600 °C, and involve the presence of aggressive sulfur, and halide species from both the biomass used and/or process additives. Detailed knowledge of the corrosion resistance of candidate process equipment alloys in these bio-oil production environments is currently lacking. Lastly, this paper summarizes our recent, ongoing efforts to assess the extent to which corrosion of bio-oil process equipment may be an issue, with the ultimate goal of providing the basis to select the lowest cost alloy grades capable of providing the long-term corrosion resistance needed for future bio-oil production plants.« less

Umbilical cord blood transplantation from HLA-identical siblings provides good results in children. These results support targeted efforts to bank family cord blood units that can be used for a sibling diagnosed with a disease which can be cured by allogeneic hematopoietic stem cell transplantation or for research that investigates the use of allogeneic or autologous cord blood cells. Over 500 patients transplanted with related cord blood units have been reported to the Eurocord registry with a 4-year overall survival of 91% for patients with non-malignant diseases and 56% for patients with malignant diseases. Main hematologic indications in children are leukemia, hemoglobinopathies or inherited hematologic, immunological or metabolic disorders. However, family-directed cord blood banking is not widely promoted; many cord blood units used in sibling transplantation have been obtained from private banks that do not meet the necessary criteria required to store these units. Marketing by private banks who predominantly store autologous cord blood units has created public confusion. There are very few current validated indications for autologous storage but some new indications might appear in the future. Little effort is devoted to provide unbiased information and to educate the public as to the distinction between the different types of banking, economic models and standards involved in such programs. In order to provide a better service for families in need, directed-family cord blood banking activities should be encouraged and closely monitored with common standards, and better information on current and future indications should be made available.

The number of alien plants escaping from cultivation into native ecosystems is increasing steadily. We provide an overview of the historical, contemporary and potential future roles of ornamental horticulture in plant invasions. We show that currently at least 75% and 93% of the global naturalised alien flora is grown in domestic and botanical gardens, respectively. Species grown in gardens also have a larger naturalised range than those that are not. After the Middle Ages, particularly in the 18th and 19th centuries, a global trade network in plants emerged. Since then, cultivated alien species also started to appear in the wild more frequently than non-cultivated aliens globally, particularly during the 19th century. Horticulture still plays a prominent role in current plant introduction, and the monetary value of live-plant imports in different parts of the world is steadily increasing. Historically, botanical gardens - an important component of horticulture - played a major role in displaying, cultivating and distributing new plant discoveries. While the role of botanical gardens in the horticultural supply chain has declined, they are still a significant link, with one-third of institutions involved in retail-plant sales and horticultural research. However, botanical gardens have also become more dependent on commercial nurseries as plant sources, particularly in North America. Plants selected for ornamental purposes are not a random selection of the global flora, and some of the plant characteristics promoted through horticulture, such as fast growth, also promote invasion. Efforts to breed non-invasive plant cultivars are still rare. Socio-economical, technological, and environmental changes will lead to novel patterns of plant introductions and invasion opportunities for the species that are already cultivated. We describe the role that horticulture could play in mediating these changes. We identify current research challenges, and call for more research efforts on the past and current role of horticulture in plant invasions. This is required to develop science-based regulatory frameworks to prevent further plant invasions. © 2018 Cambridge Philosophical Society.

Coping with treatment-related stress: effects on patient adherence in hemodialysis.
Christensen, A J; Benotsch, E G; Wiebe, J S; Lawton, W J
1995-06-01
With a modified version of the Ways of Coping Checklist, the relation of coping to adherence among 57 hemodialysis patients was examined. The association of a particular type of coping to adherence was predicted to depend on the specific type of stressful encounter being considered. As predicted, coping efforts involving planful problem solving were associated with more favorable adherence when used in response to stressors involving a relatively controllable aspect of the hemodialysis context. For less controllable stressors, coping efforts involving emotional self-control were associated with more favorable adherence. The seeking of informational support in response to an uncontrollable encounter was associated with poorer fluid-intake adherence. Confrontive coping was associated with poorer adherence for both high- and low-control situations.

Meehan, B. Timothy
Two arc flashover events occurred at the DPF Area 11 facility. These flashover events happened in the same location on the bank current delivery plates. The damage from one of these events can be seen on the left-hand side of Figure 1. Since the flashovers occurred in the same area of the bank, and the reliability of the bank is important for future DPF experiments, a failure analysis effort was initiated. Part of this failure analysis effort was an effort to understand the physical reasons behind why the flashover happened, and why it happened in the same place twice. Thismore » paper summarizes an effort to simulate the current flow in the bank in order to understand the reasons for the flashover.« less
