Informed consent mandates for abortion providers may infringe the First Amendment's freedom of speech. On the other hand, they may reinforce the physician's duty to obtain informed consent. Courts can promote both doctrines by ensuring that compelled physician speech pertains to medical facts about abortion rather than abortion ideology and that compelled speech is truthful and not misleading. © 2015 American Society of Law, Medicine & Ethics, Inc.

Exploring Visual Evidence of Human Impact on the Environment with Planetary-Scale Zoomable Timelapse Video

NASA Astrophysics Data System (ADS)

Sargent, R.; Egge, M.; Dille, P. S.; O'Donnell, G. D.; Herwig, C.

2016-12-01

Visual evidence ignites curiosity and inspires advocacy. Zoomable imagery and video on a planetary scale provides compelling evidence of human impact on the environment. Earth Timelapse places the observable impact of 30+ years of human activity into the hands of policy makers, scientists, and advocates, with fluidity and speed that supports inquiry and exploration. Zoomability enables compelling narratives and ready apprehension of environmental changes, connecting human-scale evidence to regional and ecosystem-wide trends and changes. Leveraging the power of Google Earth Engine, join us to explore 30+ years of Landset 30m RGB imagery showing glacial retreat, agricultural deforestation, irrigation expansion, and the disappearance of lakes. These narratives are enriched with datasets showing planetary forest gain/loss, annual cycles of agricultural fires, global changes in the health of coral reefs, trends in resource extraction, and of renewable energy development. We demonstrate the intuitive and inquiry-enabling power of these planetary visualizations, and provide instruction on how scientists and advocates can create and share or contribute visualizations of their own research or topics of interest.

The elusive importance effect: more failure for the Jamesian perspective on the importance of importance in shaping self-esteem.

PubMed

Marsh, Herbert W

2008-10-01

Following William James (1890/1963), many leading self-esteem researchers continue to support the Individual-importance hypothesis-that the relation between specific facets of self-concept and global self-esteem depends on the importance an individual places on each specific facet. However, empirical support for the hypothesis is surprisingly elusive, whether evaluated in terms of an importance-weighted average model, a generalized multiple regression approach for testing self-concept-by-importance interactions, or idiographic approaches. How can actual empirical support for such an intuitively appealing and widely cited psychological principle be so elusive? Hardy and Moriarty (2006), acknowledging this previous failure of the Individual-importance hypothesis, claim to have solved the conundrum, demonstrating an innovative idiographic approach that provides clear support for it. However, a critical evaluation of their new approach, coupled with a reanalysis of their data, undermines their claims. Indeed, their data provide compelling support against the Individual-importance hypothesis, which remains as elusive as ever.

Rollow, William; Cucchiara, Peter

2016-03-01

The patient-centered medical home (PCMH) model provides a compelling vision for primary care transformation, but studies of its impact have used insufficiently patient-centered metrics with inconsistent results. We propose a framework for defining patient-centered value and a new model for value-based primary care transformation: the primary care value model (PCVM). We advocate for use of patient-centered value when measuring the impact of primary care transformation, recognition, and performance-based payment; for financial support and research and development to better define primary care value-creating activities and their implementation; and for use of the model to support primary care organizations in transformation. © 2016 Annals of Family Medicine, Inc.

In Support of the Medical Apology: The Nonlegal Arguments.

Heaton, Heather A; Campbell, Ronna L; Thompson, Kristine M; Sadosty, Annie T

2016-11-01

More than 30 million people are affected annually by medical errors. Apologies can heal patients, families, and providers and, if deployed and structured appropriately, can enrich clinical encounters-yet they rarely occur. This article will address the nonlegal arguments in favor of the medical apology and discuss a structure for delivering a meaningful apology. In addition, we will review reasons why some providers feel compelled to apologize while others faced with similar circumstances do not. Medical apologies bring value to both patients and providers. Apologies can preserve therapeutic relationships and save careers for professionals by restoring their self-respect and dignity. The four R's of the ideal apology-recognition, responsibility, regret, and remedy-provide a framework to help providers apologize for unintended outcomes. When deployed and structured appropriately, apologies can heal patients, families, and providers and can enrich clinical encounters. For providers, forgiving one's self is key to professional wellbeing and continued effective practice. For patients, apologies are desirable and also serve as a conduit for often wanted emotional support from their physician. Copyright © 2016 Elsevier Inc. All rights reserved.

MutS HOMOLOG1-Derived Epigenetic Breeding Potential in Tomato1[OPEN

Kundariya, Hardik; Xu, Ying-Zhi; Sandhu, Ajay; Yu, Jiantao; Zhang, Mingfang

2015-01-01

Evidence is compelling in support of a naturally occurring epigenetic influence on phenotype expression in land plants, although discerning the epigenetic contribution is difficult. Agriculturally important attributes like heterosis, inbreeding depression, phenotypic plasticity, and environmental stress response are thought to have significant epigenetic components, but unequivocal demonstration of this is often infeasible. Here, we investigate gene silencing of a single nuclear gene, MutS HOMOLOG1 (MSH1), in the tomato (Solanum lycopersicum) ‘Rutgers’ to effect developmental reprogramming of the plant. The condition is heritable in subsequent generations independent of the MSH1-RNA interference transgene. Crossing these transgene-null, developmentally altered plants to the isogenic cv Rutgers wild type results in progeny lines that show enhanced, heritable growth vigor under both greenhouse and field conditions. This boosted vigor appears to be graft transmissible and is partially reversed by treatment with the methylation inhibitor 5-azacytidine, implying the influence of mobile, epigenetic factors and DNA methylation changes. These data provide compelling evidence for the feasibility of epigenetic breeding in a crop plant. PMID:25736208

Memory for color reactivates color processing region.

PubMed

Slotnick, Scott D

2009-11-25

Memory is thought to be constructive in nature, where features processed in different cortical regions are synthesized during retrieval. In an effort to support this constructive memory framework, the present functional magnetic resonance imaging study assessed whether memory for color reactivated color processing regions. During encoding, participants were presented with colored and gray abstract shapes. During retrieval, old and new shapes were presented in gray and participants responded 'old-colored', 'old-gray', or 'new'. Within color perception regions, color memory related activity was observed in the left fusiform gyrus, adjacent to the collateral sulcus. A retinotopic mapping analysis indicated this activity occurred within color processing region V8. The present feature specific evidence provides compelling support for a constructive view of memory.

Episodic sequence memory is supported by a theta-gamma phase code.

PubMed

Heusser, Andrew C; Poeppel, David; Ezzyat, Youssef; Davachi, Lila

2016-10-01

The meaning we derive from our experiences is not a simple static extraction of the elements but is largely based on the order in which those elements occur. Models propose that sequence encoding is supported by interactions between high- and low-frequency oscillations, such that elements within an experience are represented by neural cell assemblies firing at higher frequencies (gamma) and sequential order is encoded by the specific timing of firing with respect to a lower frequency oscillation (theta). During episodic sequence memory formation in humans, we provide evidence that items in different sequence positions exhibit greater gamma power along distinct phases of a theta oscillation. Furthermore, this segregation is related to successful temporal order memory. Our results provide compelling evidence that memory for order, a core component of an episodic memory, capitalizes on the ubiquitous physiological mechanism of theta-gamma phase-amplitude coupling.

Some experiences of NASA configuration management in providing concurrent engineering support to the Space Station Freedom program for the achievement of life cycle benefits and total quality are discussed. Three change decision experiences involving tracing requirements and automated information systems of the electrical power system are described. The potential benefits of concurrent engineering and total quality management include improved operational effectiveness, reduced logistics and support requirements, prevention of schedule slippages, and life cycle cost savings. It is shown how configuration management can influence the benefits attained through disciplined approaches and innovations that compel consideration of all the technical elements of engineering and quality factors that apply to the program development, transition to operations and in operations. Configuration management experiences involving the Space Station program's tiered management structure, the work package contractors, international partners, and the participating NASA centers are discussed.

Can walking motions improve visually induced rotational self-motion illusions in virtual reality?

PubMed

Riecke, Bernhard E; Freiberg, Jacob B; Grechkin, Timofey Y

2015-02-04

Illusions of self-motion (vection) can provide compelling sensations of moving through virtual environments without the need for complex motion simulators or large tracked physical walking spaces. Here we explore the interaction between biomechanical cues (stepping along a rotating circular treadmill) and visual cues (viewing simulated self-rotation) for providing stationary users a compelling sensation of rotational self-motion (circular vection). When tested individually, biomechanical and visual cues were similarly effective in eliciting self-motion illusions. However, in combination they yielded significantly more intense self-motion illusions. These findings provide the first compelling evidence that walking motions can be used to significantly enhance visually induced rotational self-motion perception in virtual environments (and vice versa) without having to provide for physical self-motion or motion platforms. This is noteworthy, as linear treadmills have been found to actually impair visually induced translational self-motion perception (Ash, Palmisano, Apthorp, & Allison, 2013). Given the predominant focus on linear walking interfaces for virtual-reality locomotion, our findings suggest that investigating circular and curvilinear walking interfaces offers a promising direction for future research and development and can help to enhance self-motion illusions, presence and immersion in virtual-reality systems. © 2015 ARVO.

Sources and sinks of methane beneath polar ice

Several icy moons of the outer solar system carry subsurface oceans containing many times the volume of liquid water on Earth and may provide the greatest volume of habitable space in our solar system. Functional sub-ice polar ecosystems on Earth provide compelling models for the habitability of extraterrestrial sub-ice oceans. A key feature of sub-ice environments is that most of them receive little to no solar energy. Consequently, organisms inhabiting these environments must rely on chemical energy to assimilate either carbon dioxide or organic molecules to support their metabolism. Methane can be utilized by certain bacteria as both a carbon and energy source. Isotopic data show that methane in Earth's polar lakes is derived from both biogenic and thermogenic sources. Thermogenic sources of methane in the thermokarst lakes of the north slope of Alaska yield supersaturated water columns during winter ice cover that support active populations of methanotrophs during the polar night. Methane in the permanently ice-covered lakes of the McMurdo Dry Valleys, Antarctica varies widely in concentration and is produced either by contemporary methanogenesis or is a relic from subglacial flow. Rate measurements revealed that microbial methane oxidation occurs beneath the ice in both the arctic and Antarctic lakes. The first samples collected from an Antarctic subglacial environment beneath 800 m of ice (Subglacial Lake Whillans) revealed an active microbial ecosystem that has been isolated from the atmosphere for many thousands of years. The sediments of Lake Whillans contained high levels of methane with an isotopic signature that indicates it was produced via methanogenesis. The source of this methane appears to be from the decomposition of organic carbon deposited when this region of Antarctica was covered by the sea. Collectively, data from these sub-ice environments show that methane transformations play a key role in microbial community metabolism. The discovery of functional microbial ecosystems in Earth's sub-ice aquatic environments together with what we know about the geochemistry of extraterrestrial ice-covered water worlds provide a compelling case that sub-ice oceans, such as those on Europa and Enceladus, may support microbial life.

Modeling and Reinforcement to Combat HIV: The MARCH Approach to Behavior Change

PubMed Central

Galavotti, Christine; Pappas-DeLuca, Katina A.; Lansky, Amy

2001-01-01

Theory and research suggest that behavioral interventions to prevent HIV/AIDS may be most effective when they are personalized and affectively compelling, when they provide models of desired behaviors, and when they are linked to social and cultural narratives. Effective strategies must also take into account the opportunities and obstacles present in the local environment. The Modeling and Reinforcement to Combat HIV (MARCH) projects combine key aspects of individual behavior change with efforts to change social norms. There are 2 main components to the program: entertainment as a vehicle for education (longrunning serialized dramas on radio or television portray role models evolving toward the adoption of positive behaviors) and interpersonal reinforcement at the community level (support from friends, family members, and others can help people initiate behavior changes; support through changes in social norms is necessary for behavioral effects to be sustained over time). Both media and interpersonal intervention activities should be linked to existing resources in the community and, wherever possible, provide increased access to preventive services, supplies, and other supporting elements.

Cross-Linguistic Differences in the Neural Representation of Human Language: Evidence from Users of Signed Languages

PubMed Central

Corina, David P.; Lawyer, Laurel A.; Cates, Deborah

2013-01-01

Studies of deaf individuals who are users of signed languages have provided profound insight into the neural representation of human language. Case studies of deaf signers who have incurred left- and right-hemisphere damage have shown that left-hemisphere resources are a necessary component of sign language processing. These data suggest that, despite frank differences in the input and output modality of language, core left perisylvian regions universally serve linguistic function. Neuroimaging studies of deaf signers have generally provided support for this claim. However, more fine-tuned studies of linguistic processing in deaf signers are beginning to show evidence of important differences in the representation of signed and spoken languages. In this paper, we provide a critical review of this literature and present compelling evidence for language-specific cortical representations in deaf signers. These data lend support to the claim that the neural representation of language may show substantive cross-linguistic differences. We discuss the theoretical implications of these findings with respect to an emerging understanding of the neurobiology of language. PMID:23293624

Spirituality in cancer care at the end of life.

PubMed

Ferrell, Betty; Otis-Green, Shirley; Economou, Denice

2013-01-01

There is a compelling need to integrate spirituality into the provision of quality palliative care by oncology professionals. Patients and families report the importance of spiritual, existential, and religious concerns throughout the cancer trajectory. Leading palliative care organizations have developed guidelines that define spiritual care and offer recommendations to guide the delivery of spiritual services. There is growing recognition that all team members require the skills to provide generalist spiritual support. Attention to person-centered, family-focused oncology care requires the development of a health care environment that is prepared to support the religious, spiritual, and cultural practices preferred by patients and their families. These existential concerns become especially critical at end of life and following the death for family survivors. Oncology professionals require education to prepare them to appropriately screen, assess, refer, and/or intervene for spiritual distress.

Lighter-Than-Air (LTA) "AirStation": Unmanned Aircraft System (UAS) Carrier Concept

NASA Technical Reports Server (NTRS)

Hochstetler, Ronald D.; Bosma, John; Chachad, Girish H.; Blanken, Matthew L.

2016-01-01

The advantages of utilizing an airship as an airborne carrier for support and deployment of Unmanned Aircraft Systems (UAS) are examined. Whether as a stand-alone platform or in concert with conventional aircraft, the airship UAS carrier provides a number of compelling benefits for both military and civilian missions. As a mobile base it can remain operational despite political fallout that may render ground or ocean based UAS sites unavailable. It offers the psychological impact of a power projection tool that has few geographical limits, and holds promise as a new method for cost-saving intelligence gathering. It is also adaptable for civilian variants for supporting: emergency response, security/surveillance, delivery of medical/food supplies, as well as commercial package delivery to metropolitan and remote communities. This paper presents the background on airship-aircraft operations, and explores the general airship carrier concept. Additionally, a catalog of contemporary technologies available to support the airship carrier concept are discussed, and essential elements for an Air-Station Development program proposed.

Enhancement of cognitive and neural functions through complex reasoning training: evidence from normal and clinical populations

PubMed Central

Chapman, Sandra B.; Mudar, Raksha A.

2014-01-01

Public awareness of cognitive health is fairly recent compared to physical health. Growing evidence suggests that cognitive training offers promise in augmenting cognitive brain performance in normal and clinical populations. Targeting higher-order cognitive functions, such as reasoning in particular, may promote generalized cognitive changes necessary for supporting the complexities of daily life. This data-driven perspective highlights cognitive and brain changes measured in randomized clinical trials that trained gist reasoning strategies in populations ranging from teenagers to healthy older adults, individuals with brain injury to those at-risk for Alzheimer's disease. The evidence presented across studies support the potential for Gist reasoning training to strengthen cognitive performance in trained and untrained domains and to engage more efficient communication across widespread neural networks that support higher-order cognition. The meaningful benefits of Gist training provide compelling motivation to examine optimal dose for sustained benefits as well as to explore additive benefits of meditation, physical exercise, and/or improved sleep in future studies.

Food for thought: Impact of metabolism on neuronal excitability.

PubMed

Katsu-Jiménez, Yurika; Alves, Renato M P; Giménez-Cassina, Alfredo

2017-11-01

Neuronal excitability is a highly demanding process that requires high amounts of energy and needs to be exquisitely regulated. For this reason, brain cells display active energy metabolism to support their activity. Independently of their roles as energy substrates, compelling evidence shows that the nature of the fuels that neurons use contribute to fine-tune neuronal excitability. Crosstalk of neurons with glial populations also plays a prominent role in shaping metabolic flow in the brain. In this review, we provide an overview on how different carbon substrates and metabolic pathways impact neurotransmission, and the potential implications for neurological disorders in which neuronal excitability is deregulated, such as epilepsy.

The thermoregulatory theory of yawning: what we know from over 5 years of research

PubMed Central

Gallup, Andrew C.; Eldakar, Omar T.

2012-01-01

Over the past 5 years numerous reports have confirmed and replicated the specific brain cooling and thermal window predictions derived from the thermoregulatory theory of yawning, and no study has found evidence contrary to these findings. Here we review the comparative research supporting this model of yawning among homeotherms, while highlighting a recent report showing how the expression of contagious yawning in humans is altered by seasonal climate variation. The fact that yawning is constrained to a thermal window of ambient temperature provides unique and compelling support in favor of this theory. Heretofore, no existing alternative hypothesis of yawning can explain these results, which have important implications for understanding the potential functional role of this behavior, both physiologically and socially, in humans and other animals. In discussion we stress the broader applications of this work in clinical settings, and counter the various criticisms of this theory. PMID:23293583

2016-08-01

After signing of the Same-Sex Marriage (Prohibition) Act 2013 in Nigeria, media reports portray widespread societal intolerance toward the lesbian, gay, and bisexual population. This study was conducted to assess the attitudes of university undergraduates in Lagos state, Nigeria, toward provision of healthcare services for men who have sex with men (MSM), because the 2014 same-sex marriage prohibition law stipulates a jail sentence for organizations providing services to MSM. A cross-sectional descriptive study was conducted by using self-administered questionnaires to collect information, including homophobic attitudes and views on access to healthcare, from 4000 undergraduates in 10 randomly selected faculties in two universities. During analysis, inter-university and inter-faculty comparison was carried out between medical and nonmedical students. Outright denial of healthcare services to MSM was supported by 37.6% of the 3537 undergraduates who responded, whereas denial of HIV prevention services was supported by 32.5%. However, compared with 38.7% and 34.1% of undergraduates from other faculties, 23.7% and 18.2% of medical students agreed that healthcare providers should not provide services to MSM and that MSM should not have access to HIV prevention services, respectively (P = 0.000). Although a significant proportion of the medical students supported the statement that doctors and other healthcare workers should be compelled to give priority to other groups before MSM (29.4% of medical vs. 47.2% of students from other faculties), a statistically significant difference was observed between the two groups of students. The homophobic statement with the highest support was that doctors and healthcare workers should be compelled to report MSM who come to access treatment (48.1% of medical vs. 57.4% of students from other faculties). A very high proportion of the undergraduate students had a negative attitude toward provision of healthcare services to MSM in Nigeria; the medical students were, however, less homophobic than their nonmedical counterparts. If attitudes translate to a lack of healthcare service provision to MSM, with the high burden of HIV among MSM in Nigeria, it is unlikely that the country will achieve the UNAIDS 90-90-90 target of 90% of the population knowing their HIV status, 90% of people living with HIV receiving sustained antiretroviral medication, and 90% of those receiving antiretroviral medication having viral suppression by 2020.

This finding raises a serious question on the efficacy of using zero-bias tunneling conductance peaks, by themselves, as evidence supporting the existence of topological Majorana bound states in nanowires. In the current work, we provide specific experimental protocols for tunneling spectroscopy measurements to distinguish between Andreev and Majorana bound states without invoking more demanding nonlocal measurements which have not yet been successfully performed in nanowire systems. In particular, we discuss three distinct experimental schemes involving the response of the zero-bias peak to local perturbations of the tunnel barrier, the overlap of bound states from the wire ends, and, most compellingly, introducing a sharp localized potential in the wire itself to perturb the zero-bias tunneling peaks. We provide extensive numerical simulations clarifying and supporting our theoretical predictions.

Social control and coercion in addiction treatment: towards evidence-based policy and practice.

PubMed

Wild, T Cameron

2006-01-01

Social pressures are often an integral part of the process of seeking addiction treatment. However, scientists have not developed conclusive evidence on the processes, benefits and limitations of using legal, formal and informal social control tactics to inform policy makers, service providers and the public. This paper characterizes barriers to a robust interdisciplinary analysis of social control and coercion in addiction treatment and provides directions for future research. Conceptual analysis and review of key studies and trends in the area are used to describe eight implicit assumptions underlying policy, practice and scholarship on this topic. Many policies, programmes and researchers are guided by a simplistic behaviourist and health-service perspective on social controls that (a) overemphasizes the use of criminal justice systems to compel individuals into treatment and (b) fails to take into account provider, patient and public views. Policies and programmes that expand addiction treatment options deserve support. However, drawing a firm distinction between social controls (objective use of social pressure) and coercion (client perceptions and decision-making processes) supports a parallel position that rejects treatment policies, programmes, and associated practices that create client perceptions of coercion.

Outcomes measurement in hospitals: can the system change the organization?

PubMed

Linder, J C

1992-01-01

The U.S. health care industry is in crisis--a crisis of accountability. Many believe that improved information, especially outcomes information, is at least part of the solution. If this assessment is accurate, outcomes measurement could offer a powerful opportunity to help mold our dysfunctional health care machinery into an effective infrastructure. This article explores whether implementing an outcomes measurement system in a hospital compels this kind of change. It examines the experiences of 31 hospitals that implemented a market-leading outcomes measurement system. Despite its potential, MedisGroups did not compel important improvements in hospitals' quality of care or their internal practices. Hospitals found it particularly difficult to maintain momentum throughout implementation and to structure the system as a supporting tool, rather than a driving influence, in their pursuit of operating improvements.

2001-01-01

To examine the literature from the past 20 years and identify those studies that support the economic merit of health promotion. A panel of experts was used to identify the top studies supporting the purpose of this article. Studies were chosen based on the following criteria: the study (1) examined the relationship between health risks and financial outcomes, or health promotion programs and financial outcomes; (2) provided strong and compelling financial data supporting the worth of health promotion; (3) had a high-quality methodology; (4) answered an important question or replicated important findings with superior methodology; and (5) represented U.S.-based initiatives published since 1980. After initially nominating a group of studies for consideration, panelists rated each on a scale from 1 to 3 representing their opinion of importance. Studies rating the highest were included for this discussion. Studies were analyzed by population characteristics, design, statistical tests, limitations, and results. This information was summarized for each identified article. A relationship between modifiable health risk factors and health care costs is supported by research. Health promotion interventions appear to provide positive financial returns, most notably for health care costs and absenteeism reduction. Private sector initiatives seem to be driving economic-based research. Overall, health promotion shows promising results for providing financial advantages for its sponsors; however, if this discipline is to show its true worth, considerable funding is needed from government or philanthropic sources to cover the substantial costs of quality research.

Creative Cognition and Brain Network Dynamics

PubMed Central

Beaty, Roger E.; Benedek, Mathias; Silvia, Paul J.; Schacter, Daniel L.

2015-01-01

Creative thinking is central to the arts, sciences, and everyday life. How does the brain produce creative thought? A series of recently published papers has begun to provide insight into this question, reporting a strikingly similar pattern of brain activity and connectivity across a range of creative tasks and domains, from divergent thinking to poetry composition to musical improvisation. This research suggests that creative thought involves dynamic interactions of large-scale brain systems, with the most compelling finding being that the default and executive control networks, which can show an antagonistic relationship, actually cooperate during creative cognition and artistic performance. These findings have implications for understanding how brain networks interact to support complex cognitive processes, particularly those involving goal-directed, self-generated thought.

Berkeley Lab's George Smoot won the 2006 Physics Nobel Prize, together with John Mather of NASA Goddard Space Flight Center, for "the discovery of the blackbody form and anisotropy of the cosmic microwave background radiation." The anisotropy showed as small variations in the map of the early universe. This research looks back into the infant universe and provides a better understanding of the origin of galaxies and stars. The cosmic background radiation is a tool to understand the structure and history of the universe and the structure of space-time. These observations have provided increased support for the big bang theory of the universe's origin. The Cosmic Background Explorer (COBE) NASA satellite, launched in 1989, carries instruments that measured various aspects of cosmic microwave background radiation, and produced the data for these compelling scientific results, which opened up a field that continues very actively today.

Testing and extending the group engagement model: linkages between social identity, procedural justice, economic outcomes, and extrarole behavior.

Blader, Steven L; Tyler, Tom R

2009-03-01

Two field studies tested and extended the group engagement model (Tyler & Blader, 2000, Tyler & Blader, 2003) by examining the model with regard to employee extrarole behavior. Consistent with the group engagement model's predictions, results of these studies indicate that the social identities employees form around their work groups and their organizations are strongly related to whether employees engage in extrarole behaviors. Moreover, the studies demonstrated that social identity explains the impact of other factors that have previously been linked to extrarole behavior. In particular, the findings indicate that social identity mediates the effect of procedural justice judgments and economic outcomes on supervisor ratings of extrarole behavior. Overall, these studies provide compelling indication that social identity is an important determinant of behavior within work organizations and provide strong support for the application of the group engagement model in organizational settings.

THE NATURE AND SCOPE OF STRESSFUL SPOUSAL CAREGIVING RELATIONSHIPS

PubMed Central

Davis, Linda Lindsey; Gilliss, Catherine L.; Deshefy-Longhi, Tess; Chestnutt, Deborah H.; Molloy, Margory

2013-01-01

The caregiving literature provides compelling evidence that caregiving burden and depressive symptoms are linked with stressful care relationships however relational difficulties around caregiving are seldom described in the literature. This paper presents findings from content analysis of baseline interviews with 40 Alzheimer’s disease and Parkinson’s disease spousal caregivers enrolled in a home care skill training trial who identified their care relationship as a source of care burden. Disappointment and sadness about the loss of the relationship; tension within the relationship; and care decision conflicts within the relationship were recurrent themes of relational stress in caregiving. These spousal caregivers had relationship quality scores below the mean and burden and depressive symptom scores above the means of the other caregivers in the study. These findings provide support for developing dyadic interventions that help spouses manage relational losses, care-related tensions and care decision making conflicts. PMID:21531858

Briggs, Charles L; Nichter, Mark

2009-07-01

In this article we assess accounts of the H1N1 virus or "swine flu" to draw attention to the ways in which discourse about biosecurity and global health citizenship during times of pandemic alarms supports calls for the creation of global surveillance systems and naturalizes forms of governance. We propose a medical anthropology of epidemics to complement an engaged anthropology aimed at better and more critical forms of epidemic surveillance. A medical anthropology of epidemics provides insights into factors and actors that shape the ongoing production of knowledge about epidemics, how dominant and competing accounts circulate and interact, how different stakeholders (citizens, politicians, journalists, and policymakers) access and interpret information available from different sources-including through a variety of new digital venues-and what they do with it. These insights together provide a compelling agenda for medical anthropology and anyone working in health-related fields.

Dopamine prediction errors in reward learning and addiction: from theory to neural circuitry

PubMed Central

Keiflin, Ronald; Janak, Patricia H.

2015-01-01

Summary Midbrain dopamine (DA) neurons are proposed to signal reward prediction error (RPE), a fundamental parameter in associative learning models. This RPE hypothesis provides a compelling theoretical framework for understanding DA function in reward learning and addiction. New studies support a causal role for DA-mediated RPE activity in promoting learning about natural reward; however, this question has not been explicitly tested in the context of drug addiction. In this review, we integrate theoretical models with experimental findings on the activity of DA systems, and on the causal role of specific neuronal projections and cell types, to provide a circuit-based framework for probing DA-RPE function in addiction. By examining error-encoding DA neurons in the neural network in which they are embedded, hypotheses regarding circuit-level adaptations that possibly contribute to pathological error-signaling and addiction can be formulated and tested.

Kohn, M S; Sun, J; Knoop, S; Shabo, A; Carmeli, B; Sow, D; Syed-Mahmood, T; Rapp, W

2014-08-15

This survey explores the role of big data and health analytics developed by IBM in supporting the transformation of healthcare by augmenting evidence-based decision-making. Some problems in healthcare and strategies for change are described. It is argued that change requires better decisions, which, in turn, require better use of the many kinds of healthcare information. Analytic resources that address each of the information challenges are described. Examples of the role of each of the resources are given. There are powerful analytic tools that utilize the various kinds of big data in healthcare to help clinicians make more personalized, evidenced-based decisions. Such resources can extract relevant information and provide insights that clinicians can use to make evidence-supported decisions. There are early suggestions that these resources have clinical value. As with all analytic tools, they are limited by the amount and quality of data. Big data is an inevitable part of the future of healthcare. There is a compelling need to manage and use big data to make better decisions to support the transformation of healthcare to the personalized, evidence-supported model of the future. Cognitive computing resources are necessary to manage the challenges in employing big data in healthcare. Such tools have been and are being developed. The analytic resources, themselves, do not drive, but support healthcare transformation.

Navigating the Path to a Biomedical Science Career

NASA Astrophysics Data System (ADS)

Zimmerman, Andrea McNeely

The number of biomedical PhD scientists being trained and graduated far exceeds the number of academic faculty positions and academic research jobs. If this trend is compelling biomedical PhD scientists to increasingly seek career paths outside of academia, then more should be known about their intentions, desires, training experiences, and career path navigation. Therefore, the purpose of this study was to understand the process through which biomedical PhD scientists are trained and supported for navigating future career paths. In addition, the study sought to determine whether career development support efforts and opportunities should be redesigned to account for the proportion of PhD scientists following non-academic career pathways. Guided by the social cognitive career theory (SCCT) framework this study sought to answer the following central research question: How does a southeastern tier 1 research university train and support its biomedical PhD scientists for navigating their career paths? Key findings are: Many factors influence PhD scientists' career sector preference and job search process, but the most influential were relationships with faculty, particularly the mentor advisor; Planned activities are a significant aspect of the training process and provide skills for career success; and Planned activities provided skills necessary for a career, but influential factors directed the career path navigated. Implications for practice and future research are discussed.

Designing for Broad Understanding of Science.

With the acceleration and increasing complexity of macro-scale problems such as climate change, the need for scientists to ensure that their work is understood has become urgent. As citizens and recipients of public funds for research, scientists have an obligation to communicate their findings in ways many people can understand. However, developing translations that are broadly accessible without being "dumbed down" can be challenging. Fortunately, tenets of visual literacy, combined with narrative methods, can help to convey scientific knowledge with fidelity, while sustaining viewers' interest. Here we outline strategies for such translating, with an emphasis on visual approaches. Among the examples is an innovative, NSF-funded professional development initiative in which National Park rangers use scientists' imagery to create compelling explanations for the visiting public. Thoughtful visualizations based on interpretive images, motion pictures, 3D animations and augmented, immersive experiences complement the impact of the natural resource and enhance the role of the park ranger. The visualizations become scaffolds for participatory exchanges in which the ranger transcends the traditional roles of information-holder and presenter, to facilitate provocative conversations that provide members of the public with enjoyable experiences and well-founded bases for reflection and ultimately understanding. The process of generating the supporting visualizations benefits from partnerships with design professionals, who develop opportunities for engaging the public by translating important scientific findings and messages in compelling and memorable ways.

2018-06-01

Although widely cited as strong evidence that sexual selection has shaped human facial-attractiveness judgments, findings suggesting that women's preferences for masculine characteristics in men's faces are related to women's hormonal status are equivocal and controversial. Consequently, we conducted the largest-ever longitudinal study of the hormonal correlates of women's preferences for facial masculinity ( N = 584). Analyses showed no compelling evidence that preferences for facial masculinity were related to changes in women's salivary steroid hormone levels. Furthermore, both within-subjects and between-subjects comparisons showed no evidence that oral contraceptive use decreased masculinity preferences. However, women generally preferred masculinized over feminized versions of men's faces, particularly when assessing men's attractiveness for short-term, rather than long-term, relationships. Our results do not support the hypothesized link between women's preferences for facial masculinity and their hormonal status.

Flies, worms and the Free Radical Theory of ageing.

PubMed

Clancy, David; Birdsall, John

2013-01-01

Drosophila and Caenorhabditis elegans have provided the largest body of evidence addressing the Free Radical Theory of ageing, however the evidence has not been unequivocally supportive. Oxidative damage to DNA is probably not a major contributor, damage to lipids is assuming greater importance and damage to proteins probably the source of pathology. On balance the evidence does not support a primary role of oxidative damage in ageing in C. elegans, perhaps because of its particular energy metabolic and stress resistance profile. Evidence is more numerous, varied and consistent and hence more compelling for Drosophila, although not conclusive. However there is good evidence for a role of oxidative damage in later life pathology. Future work should: 1/ make more use of protein oxidative damage measurements; 2/ use inducible transgenic systems or pharmacotherapy to ensure genetic equivalence of controls and avoid confounding effects during development; 3/ to try to delay ageing, target interventions which reduce and/or repair protein oxidative damage.

In this issue of the Journal, Ghiasvand et al. (Am J Epidemiol. 2017;185(3):147-156) present results from a longitudinal study of the association between indoor tanning and melanoma in a large cohort of Norwegian women. These new data further support previous findings on the damaging effects of tanning bed exposure on women, particularly young women. The authors present compelling evidence that early exposure to tanning beds advances the date of diagnosis of melanoma by at least 2 years. With a strong design and a large cohort followed for a mean of 13.7 years, this study lends additional support to previous evidence of the negative effects of tanning beds and provides further justification for stronger policy initiatives designed to reduce tanning bed use among young women. © The Author 2016.

The Cascadia Paradox: Understanding Mantle Flow in the Cascadia Subduction System

NASA Astrophysics Data System (ADS)

Long, M. D.

2015-12-01

The pattern of mantle flow in subduction systems, and the processes that control the mantle flow field, is a fundamental but still poorly understood aspect of subduction dynamics. Mantle flow plays a key role in controlling the transport of volatiles and melt in the wedge, deformation of the overriding plate, mass transfer between the upper and lower mantle, and the morphology and dynamics of slabs. The Cascadia subduction zone provides a compelling system in which to understand the controls on mantle flow, particularly given the dense geophysical observations provided by EarthScope, GeoPRISMS, the Cascadia Initiative, and related efforts. Cascadia is a particularly intriguing system because observations of seismic anisotropy, which provide relatively direct constraints on mantle flow, seem to yield contradictory views of the mantle flow field in different parts of the system. Observations of seismic anisotropy on the overriding plate apparently require a significant component of three-dimensional, toroidal flow around the slab edge, while new observations from offshore stations are compellingly explained with a simple two-dimensional entrained flow model. Recent evidence from seismic tomography for the fragmentation of the Cascadia slab at depth provides a further puzzle: how can a fragmented slab provide a driving force for either two-dimensional entrained flow or three-dimensional toroidal flow due to slab rollback? I will present a synthesis of recent observations of seismic anisotropy in the Cascadia subduction system, and how they can be integrated with constraints from geodynamical modeling, geochemistry, and the history and timing of Pacific Northwest volcanism. I will discuss the compelling but contradictory evidence for each of the endmember mantle flow models (two-dimensional entrained flow vs. three-dimensional toroidal flow) and explore possible avenues for resolving the Cascadia Paradox.

The recent attempt by Horowitz (2017) to develop an "olfactory mirror" test of self-recognition in domestic dogs raises some important questions about the kinds of data that are required to provide definitive evidence for self-recognition in dogs and other species. We conclude that the "olfactory mirror" constitutes a compelling analog to the mark test for mirror self-recognition in primates, but despite claims to the contrary neither dogs, elephants, dolphins, magpies, horses, manta rays, squid, nor ants have shown compelling, reproducible evidence for self-recognition in any modality.

Using Co-production to Enhance Co-production: Cultivating institutional capacity through exchange between climate science, social science, and practice

NASA Astrophysics Data System (ADS)

Kalafatis, S.

2015-12-01

Many climate scientists and boundary organizations have accumulated years of experience providing decision support for climate adaptation related to landscape change. The Great Lakes Integrated Sciences + Assessments (GLISA) is one such organization that has developed a reputation for providing stakeholders with climate change decision support throughout the Great Lakes region of North America. After five years of applied outreach, GLISA climate scientists working with practitioners identified three common limitations across projects that were slowing down the use of information, describing them as mismatched terminology, unrealistic expectations, and disordered integration. Discussions with GLISA-affiliated social scientists revealed compelling parallels between these observations and the existing social science literature on the persistent "usability gap" in information use as well as opportunities to preemptively overcome these barriers. The discovery of these overlaps between the climate scientists' experience of barriers and the social science literature as well as strategies to systematically address them demonstrate the potential for boundary organizations to act as incubators of more and more efficient co-production over time. To help illustrate these findings, this presentation also provides an example of decision-making for adaptation in the face of landscape change in which GLISA scientists assisted Isle Royale National Park with assessing the implications of future ecological transitions for current wildlife management efforts.

Exploring Physics with Computer Animation and PhysGL

Bensky, T. J.

2016-10-01

This book shows how the web-based PhysGL programming environment (http://physgl.org) can be used to teach and learn elementary mechanics (physics) using simple coding exercises. The book's theme is that the lessons encountered in such a course can be used to generate physics-based animations, providing students with compelling and self-made visuals to aid their learning. Topics presented are parallel to those found in a traditional physics text, making for straightforward integration into a typical lecture-based physics course.

American Akicita: Indigenous American warriors and military service.

PubMed

McDonald, J Douglas

2017-08-01

Indigenous Americans (i.e., Native/American Indians, AK natives, Pacific Islanders) have consistently volunteered for military service at greater rates than any other ethnic group, including the majority culture, since the early days of the country. This article is an introduction to the special section which includes a number of outstanding papers that provide an innovative and compelling effort to overcome the challenges of casualties from war and render effective and culturally informed care. These manuscripts describe culturally appropriate considerations of suicide (O'Keefe), family involvement and access to care (Whealin), and telehealth for treatment of rural Native veterans (Goss). Challenging and complex treatment needs call for equally mindful and competent approaches. These authors and providers present compelling examples of addressing these needs in working with our Wounded Warriors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Ecological restoration should be redefined for the twenty-first century.

PubMed

Martin, David M

2017-09-24

Forty years ago, ecological restoration was conceptualized through a natural science lens. Today, ecological restoration has evolved into a social and scientific concept. The duality of ecological restoration is acknowledged in guidance documents on the subject but is not apparent in its definition. Current definitions reflect our views about what ecological restoration does but not why we do it. This viewpoint does not give appropriate credit to contributions from social sciences, nor does it provide compelling goals for people with different motivating rationales to engage in or support restoration. In this study, I give a concise history of the conceptualization and definition of ecological restoration, and I propose an alternative definition and corresponding viewpoint on restoration goal-setting to meet twenty-first century scientific and public inquiry.

Psychological First Aid

Shultz, James M; Forbes, David

2014-01-01

Psychological first aid (PFA) has become the flagship early intervention for disaster survivors, with recent adaptations for disaster responders, in the post-9/11 era. PFA is broadly endorsed by expert consensus and integrated into guidelines for mental health and psychosocial support in disasters and extreme events. PFA frameworks are proliferating, with increasing numbers of models developed for delivery by a range of providers for use with an expanding array of target populations. Despite popularity and promotion there remains a dearth of evidence for effectiveness and recent independent reviews of PFA have highlighted this important gap. This commentary juxtaposes the current propagation of PFA against the compelling need to produce evidence for effectiveness and suggests a series of actions to prioritize and expedite real-time, real-event field evaluation of PFA.

Compulsive overeating as an addiction disorder. A review of theory and evidence.

PubMed

Davis, Caroline; Carter, Jacqueline C

2009-08-01

In this paper we argue that compulsive overeating has compelling similarities to conventional drug addiction. Our case is based on their comparable clinical features, the biological mechanisms they have in common, and on evidence that the two disorders have a shared diathesis. In making the argument for overeating as an addictive behaviour, it is clearly not appropriate to include all cases of excessive food consumption in this taxon. Nor are we claiming that obesity and addiction are one and the same. However, it is proposed that Binge Eating Disorder (BED) is a phenotype particularly well-suited to such a conceptualization, and that sound clinical and scientific evidence exists to support this viewpoint. We have provided some recommendations for treatment modifications that recognize the similarities between treating drug dependence and compulsive overeating.

The music instinct: the evolutionary basis of musicality.

PubMed

Mithen, Steven

2009-07-01

Why does music pervade our lives and those of all known human beings living today and in the recent past? Why do we feel compelled to engage in musical activity, or at least simply enjoy listening to music even if we choose not to actively participate? I argue that this is because musicality--communication using variations in pitch, rhythm, dynamics and timbre, by a combination of the voice, body (as in dance), and material culture--was essential to the lives of our pre-linguistic hominin ancestors. As a consequence we have inherited a desire to engage with music, even if this has no adaptive benefit for us today as a species whose communication system is dominated by spoken language. In this article I provide a summary of the arguments to support this view.

Creative Cognition and Brain Network Dynamics.

PubMed

Beaty, Roger E; Benedek, Mathias; Silvia, Paul J; Schacter, Daniel L

2016-02-01

Creative thinking is central to the arts, sciences, and everyday life. How does the brain produce creative thought? A series of recently published papers has begun to provide insight into this question, reporting a strikingly similar pattern of brain activity and connectivity across a range of creative tasks and domains, from divergent thinking to poetry composition to musical improvisation. This research suggests that creative thought involves dynamic interactions of large-scale brain systems, with the most compelling finding being that the default and executive control networks, which can show an antagonistic relation, tend to cooperate during creative cognition and artistic performance. These findings have implications for understanding how brain networks interact to support complex cognitive processes, particularly those involving goal-directed, self-generated thought.

The Mirror Illusion’s Effects on Body State Estimation

PubMed Central

Soliman, Tamer M.; Buxbaum, Laurel J.; Jax, Steven A.

2016-01-01

The mirror illusion uses a standard mirror to create a compelling illusion in which movements of one limb seem to be made by the other hidden limb. In this paper we adapt a motor control framework to examine which estimates of the body’s configuration are affected by the illusion. We propose that the illusion primarily alters estimates related to upcoming states of the body (the desired state and the predicted state), with smaller effects on the estimate of the body state prior to movement initiation. Support for this proposal is provided both by behavioral effects of the illusion as well as neuroimaging evidence from one neural region, V6A, that is critically involved in the mirror illusion and limb state estimation more generally.

2013-01-01

Research in sub-Saharan Africa has shown significant diversity in how HIV influences infected couples’ fertility intentions. Supporting HIV-infected, sero-concordant couples in sub-Saharan Africa to make informed choices about their fertility options has not received sufficient attention. In-depth interviews were conducted among 23 HIV-positive, sero-concordant married couples in Kenya, to better understand how HIV impacted fertility intentions. HIV compelled many to reconsider fertility plans, sometimes promoting childbearing intentions in some individuals but often reducing fertility plans among most, largely due to fears of early death, health concerns, stigma, perinatal HIV transmission and financial difficulties (particularly in men). Preferences for sons and large families influenced some couples’ intentions to continue childbearing, although none had discussed their intentions with health care providers. Additional support and services for HIV-infected, sero-concordant couples are needed. Family planning counselling should be tailored to the unique concerns of HIV-infected couples, addressing perinatal transmission but also individual, couple-level, and socio-cultural fertility expectations. Community-level programmes are needed to reduce stigma and make HIV-infected couples more comfortable in discussing fertility intentions with health care providers. PMID:23885924

A Reinforcement Sensor Embedded Vertical Handoff Controller for Vehicular Heterogeneous Wireless Networks

PubMed Central

Li, Limin; Xu, Yubin; Soong, Boon-Hee; Ma, Lin

2013-01-01

Vehicular communication platforms that provide real-time access to wireless networks have drawn more and more attention in recent years. IEEE 802.11p is the main radio access technology that supports communication for high mobility terminals, however, due to its limited coverage, IEEE 802.11p is usually deployed by coupling with cellular networks to achieve seamless mobility. In a heterogeneous cellular/802.11p network, vehicular communication is characterized by its short time span in association with a wireless local area network (WLAN). Moreover, for the media access control (MAC) scheme used for WLAN, the network throughput dramatically decreases with increasing user quantity. In response to these compelling problems, we propose a reinforcement sensor (RFS) embedded vertical handoff control strategy to support mobility management. The RFS has online learning capability and can provide optimal handoff decisions in an adaptive fashion without prior knowledge. The algorithm integrates considerations including vehicular mobility, traffic load, handoff latency, and network status. Simulation results verify that the proposed algorithm can adaptively adjust the handoff strategy, allowing users to stay connected to the best network. Furthermore, the algorithm can ensure that RSUs are adequate, thereby guaranteeing a high quality user experience. PMID:24193101

Effective Vaccine Communication during the Disneyland Measles Outbreak

Broniatowski, David Andre; Hilyard, Karen M.; Dredze, Mark

2016-01-01

Vaccine refusal rates have increased in recent years, highlighting the need for effective risk communication, especially over social media. Fuzzy-trace theory predicts that individuals encode bottom-line meaning ("gist") and statistical information ("verbatim") in parallel and that articles expressing a clear gist will be most compelling. We coded news articles (n=4,686) collected during the 2014–2015 Disneyland measles for content including statistics, stories, or opinions containing bottom-line gists regarding vaccines and vaccine-preventable illnesses. We measured the extent to which articles were compelling by how frequently they were shared on Facebook. The most widely shared articles expressed bottom-line opinions, although articles containing statistics were also more likely to be shared than articles lacking statistics. Stories had limited impact on Facebook shares. Results support Fuzzy Trace Theory's predictions regarding the distinct yet parallel impact of categorical gist and statistical verbatim information on public health communication. PMID:27179915

We present a progressive effort to deliver online education and outreach resources in collaboration with the Apple Learning Interchange, a free community for educators. We have created a resource site with astronomy activities, video training for the activities, and the possibility of interactive training through video chat services. Also in development is an online textbook for graduate and advanced undergraduate courses in stellar evolution, featuring an updatable and annotated text with multimedia content, online lectures, podcasts, and a framework for interactive simulation activities. Both sites will be highly interactive, combining online discussions, the opportunity for live video interaction, and a growing library of student work samples. This effort promises to provide a compelling model for collaboration between science educators and corporations. As scientists, we provide content knowledge and a compelling reason to communicate, while Apple provides technical expertise, a deep knowledge of online education, and a way for us to reach a wide audience of higher education, community outreach, and K-12 educators.

Frontal Midline Theta Reflects Anxiety and Cognitive Control: Meta-Analytic Evidence

PubMed Central

Cavanagh, James F.; Shackman, Alexander J.

2014-01-01

Evidence from imaging and anatomical studies suggests that the midcingulate cortex (MCC) is a dynamic hub lying at the interface of affect and cognition. In particular, this neural system appears to integrate information about conflict and punishment in order to optimize behavior in the face of action-outcome uncertainty. In a series of meta-analyses, we show how recent human electrophysiological research provides compelling evidence that frontal-midline theta signals reflecting MCC activity are moderated by anxiety and predict adaptive behavioral adjustments. These findings underscore the importance of frontal theta activity to a broad spectrum of control operations. We argue that frontal-midline theta provides a neurophysiologically plausible mechanism for optimally adjusting behavior to uncertainty, a hallmark of situations that elicit anxiety and demand cognitive control. These observations compel a new perspective on the mechanisms guiding motivated learning and behavior and provide a framework for understanding the role of the MCC in temperament and psychopathology.

2014-01-01

Summary Objectives This survey explores the role of big data and health analytics developed by IBM in supporting the transformation of healthcare by augmenting evidence-based decision-making. Methods Some problems in healthcare and strategies for change are described. It is argued that change requires better decisions, which, in turn, require better use of the many kinds of healthcare information. Analytic resources that address each of the information challenges are described. Examples of the role of each of the resources are given. Results There are powerful analytic tools that utilize the various kinds of big data in healthcare to help clinicians make more personalized, evidenced-based decisions. Such resources can extract relevant information and provide insights that clinicians can use to make evidence-supported decisions. There are early suggestions that these resources have clinical value. As with all analytic tools, they are limited by the amount and quality of data. Conclusion Big data is an inevitable part of the future of healthcare. There is a compelling need to manage and use big data to make better decisions to support the transformation of healthcare to the personalized, evidence-supported model of the future. Cognitive computing resources are necessary to manage the challenges in employing big data in healthcare. Such tools have been and are being developed. The analytic resources, themselves, do not drive, but support healthcare transformation. PMID:25123736

Decreased zinc in the development and progression of malignancy: an important common relationship and potential for prevention and treatment of carcinomas

PubMed Central

Costello, Leslie C.; Franklin, Renty B.

2016-01-01

Introduction Efficacious chemotherapy does not exist for treatment or prevention of prostate, liver, and pancreatic carcinomas, and some other cancers that exhibit decreased zinc in malignancy. Zinc treatment offers a potential solution; but its support has been deterred by adverse bias. Areas covered 1. The clinical and experimental evidence for the common ZIP transporter/Zn down regulation in these cancers. 2. The evidence for a zinc approach to prevent and/or treat these carcinomas. 3. The issues that introduce bias against support for the zinc approach. Expert opinion ZIP/Zn downregulation is a clinically established common event in prostate, hepatocellular and pancreatic cancers. 2. Compelling evidence supports the plausibility that a zinc treatment regimen will prevent development of malignancy and termination of progressing malignancy in these cancers; and likely other carcinomas that exhibit decreased zinc. 3. Scientifically-unfounded issues that oppose this ZIP/Zn relationship have introduced bias against support for research and funding of a zinc treatment approach. 4. The clinically-established and supporting experimental evidence provide the scientific credibility that should dictate the support for research and funding of a zinc approach for the treatment and possible prevention of these cancers. 5. This is in the best interest of the medical community and the public-at-large. PMID:27885880

On the lack of evidence that non-human animals possess anything remotely resembling a 'theory of mind'.

Penn, Derek C; Povinelli, Daniel J

2007-04-29

After decades of effort by some of our brightest human and non-human minds, there is still little consensus on whether or not non-human animals understand anything about the unobservable mental states of other animals or even what it would mean for a non-verbal animal to understand the concept of a 'mental state'. In the present paper, we confront four related and contentious questions head-on: (i) What exactly would it mean for a non-verbal organism to have an 'understanding' or a 'representation' of another animal's mental state? (ii) What should (and should not) count as compelling empirical evidence that a non-verbal cognitive agent has a system for understanding or forming representations about mental states in a functionally adaptive manner? (iii) Why have the kind of experimental protocols that are currently in vogue failed to produce compelling evidence that non-human animals possess anything even remotely resembling a theory of mind? (iv) What kind of experiments could, at least in principle, provide compelling evidence for such a system in a non-verbal organism?

Attractiveness Is Multimodal: Beauty Is Also in the Nose and Ear of the Beholder.

PubMed

Groyecka, Agata; Pisanski, Katarzyna; Sorokowska, Agnieszka; Havlíček, Jan; Karwowski, Maciej; Puts, David; Roberts, S Craig; Sorokowski, Piotr

2017-01-01

Attractiveness plays a central role in human non-verbal communication and has been broadly examined in diverse subfields of contemporary psychology. Researchers have garnered compelling evidence in support of the evolutionary functions of physical attractiveness and its role in our daily lives, while at the same time, having largely ignored the significant contribution of non-visual modalities and the relationships among them. Acoustic and olfactory cues can, separately or in combination, strongly influence the perceived attractiveness of an individual and therefore attitudes and actions toward that person. Here, we discuss the relative importance of visual, auditory and olfactory traits in judgments of attractiveness, and review neural and behavioral studies that support the highly complex and multimodal nature of person perception. Further, we discuss three alternative evolutionary hypotheses aimed at explaining the function of multiple indices of attractiveness. In this review, we provide several lines of evidence supporting the importance of the voice, body odor, and facial and body appearance in the perception of attractiveness and mate preferences, and therefore the critical need to incorporate cross-modal perception and multisensory integration into future research on human physical attractiveness.

The Auditory Comprehension of Wh-Questions in Aphasia: Support for the Intervener Hypothesis.

PubMed

Sheppard, Shannon M; Walenski, Matthew; Love, Tracy; Shapiro, Lewis P

2015-06-01

This study examines 3 hypotheses about the processing of wh-questions in both neurologically healthy adults and adults with Broca's aphasia. We used an eye tracking while listening method with 32 unimpaired participants (Experiment 1) and 8 participants with Broca's aphasia (Experiment 2). Accuracy, response time, and online gaze data were collected. In Experiment 1, we established a baseline for how unimpaired processing and comprehension of 4 types of wh-question (subject- and object-extracted who- and which-questions) manifest. There was no unambiguous support found for any of the 3 hypotheses in Experiment 1. In Experiment 2 with the Broca's participants, however, we found significantly lower accuracy, slower response times, and increased interference in our gaze data in the object-extracted which-questions relative to the other conditions. Our results provide support for the intervener hypothesis, which states that sentence constructions that contain an intervener (a lexical noun phrase) between a displaced noun phrase and its gap site result in a significant processing disadvantage relative to other constructions. We argue that this hypothesis offers a compelling explanation for the comprehension deficits seen in some participants with Broca's aphasia.

Electric Fields and Enzyme Catalysis

PubMed Central

Fried, Stephen D.; Boxer, Steven G.

2017-01-01

What happens inside an enzyme’s active site to allow slow and difficult chemical reactions to occur so rapidly? This question has occupied biochemists’ attention for a long time. Computer models of increasing sophistication have predicted an important role for electrostatic interactions in enzymatic reactions, yet this hypothesis has proved vexingly difficult to test experimentally. Recent experiments utilizing the vibrational Stark effect make it possible to measure the electric field a substrate molecule experiences when bound inside its enzyme’s active site. These experiments have provided compelling evidence supporting a major electrostatic contribution to enzymatic catalysis. Here, we review these results and develop a simple model for electrostatic catalysis that enables us to incorporate disparate concepts introduced by many investigators to describe how enzymes work into a more unified framework stressing the importance of electric fields at the active site.

Breakdown of the brain’s functional network modularity with awareness

PubMed Central

Godwin, Douglass; Barry, Robert L.; Marois, René

2015-01-01

Neurobiological theories of awareness propose divergent accounts of the spatial extent of brain changes that support conscious perception. Whereas focal theories posit mostly local regional changes, global theories propose that awareness emerges from the propagation of neural signals across a broad extent of sensory and association cortex. Here we tested the scalar extent of brain changes associated with awareness using graph theoretical analysis applied to functional connectivity data acquired at ultra-high field while subjects performed a simple masked target detection task. We found that awareness of a visual target is associated with a degradation of the modularity of the brain’s functional networks brought about by an increase in intermodular functional connectivity. These results provide compelling evidence that awareness is associated with truly global changes in the brain’s functional connectivity. PMID:25759440

Some forms of synaptic plasticity require rapid, local activation of protein synthesis. Although this is thought to reflect recruitment of mRNAs to free ribosomes, this would limit the speed and magnitude of translational activation. Here we provide compelling in situ evidence supporting an alternative model in which synaptic mRNAs are transported as stably paused polyribosomes. Remarkably, we show that metabotropic glutamate receptor activation allows the synthesis of proteins that lead to a functional long-term depression phenotype even when translation initiation has been greatly reduced. Thus, neurons evolved a unique mechanism to swiftly translate synaptic mRNAs into functional protein upon synaptic signaling using stalled polyribosomes to bypass the rate-limiting step of translation initiation. Because dysregulated plasticity is implicated in neurodevelopmental and psychiatric disorders such as fragile X syndrome, this work uncovers a unique translational target for therapies.

The networked health enterprise: a vision for 2008.

PubMed

Stead, W W

1998-01-01

Informatics and information technology hold the promise of a consumer-centered health enterprise--one that provides quality care at a cost society is willing to pay; one where need-based, adaptive, competency-based learning results in cost-effectiveness of health education; one where team-based health and learning on demand, coupled with monitoring of process outcomes and network access to expertise, guarantee quality. The barriers to this promise are the professional guilds, the cross-subsidies that support the health enterprise of 1998, and the lack of respect for privacy. Collectively, the informatics community needs to develop a compelling vision that will galvanize the health community to action. If the health community does not step up to this challenge, consumers will take advantage of disintermediation. Empowered by the network, they will go outside the system into hands that meet their needs.

Extraterrestrial Life: Life on Mars - Then and Now

NASA Technical Reports Server (NTRS)

Arrhenius, Gustaf; Mojzsis, Stephen

1996-01-01

The recent claim to have identified possible signs of ancient life on Mars has been widely publicized and discussed. The authors conceded that none of the half-dozen pieces of evidence adduced in their paper individually provided strong support for extraterrestrial life, though they argued that the pieces added up to a case worth considering. Most - perhaps all - of the observed phenomena have counterparts in the inorganic world, so even the combination does not make a compelling case that there was ever life on Mars. Nevertheless, the importance of the problem has justified bringing the results to general attention. The paper has focussed interest on the origin and possible ubiquity of life, and on how we can design techniques capable of giving a more definitive answer to the question of whether there is, or has ever been, life elsewhere in the Universe.

Methods Used in Game Development to Foster FLOW

Jeppsen, Isaac Ben

2010-01-01

Games designed for entertainment have a rich history of providing compelling experiences. From consoles to PCs, games have managed to present intuitive and effective interfaces for a wide range of game styles to successfully allow users to "walk-up-and-play". Once a user is hooked, successful games artfully present challenging experiences just within reach of a user's ability, weaving each task and achievement into a compelling and engaging experience. In this paper, engagement is discussed in terms of the psychological theory of Flow. I argue that engagement should be one of the primary goals when developing a serious game and I discuss the best practices and techniques that have emerged from traditional video game development which help foster the creation of engaging, high Flow experiences.

Menstrual cycle phase alters women's sexual preferences for composers of more complex music.

PubMed

Charlton, Benjamin D

2014-06-07

Over 140 years ago Charles Darwin first argued that birdsong and human music, having no clear survival benefit, were obvious candidates for sexual selection. Whereas the first contention is now universally accepted, his theory that music is a product of sexual selection through mate choice has largely been neglected. Here, I provide the first, to my knowledge, empirical support for the sexual selection hypothesis of music evolution by showing that women have sexual preferences during peak conception times for men that are able to create more complex music. Two-alternative forced-choice experiments revealed that woman only preferred composers of more complex music as short-term sexual partners when conception risk was highest. No preferences were displayed when women chose which composer they would prefer as a long-term partner in a committed relationship, and control experiments failed to reveal an effect of conception risk on women's preferences for visual artists. These results suggest that women may acquire genetic benefits for offspring by selecting musicians able to create more complex music as sexual partners, and provide compelling support for Darwin's assertion 'that musical notes and rhythm were first acquired by the male or female progenitors of mankind for the sake of charming the opposite sex'.

Evaluating a Modeling Curriculum by Using Heuristics for Productive Disciplinary Engagement

Passmore, Cynthia

2010-01-01

The BIO2010 report provided a compelling argument for the need to create learning experiences for undergraduate biology students that are more authentic to modern science. The report acknowledged the need for research that could help practitioners successfully create and reform biology curricula with this goal in mind. Our objective in this article was to explore how a set of six design heuristics could be used to evaluate the potential of curricula to support productive learning experiences for science students. We drew on data collected during a long-term study of an undergraduate traineeship that introduced students to mathematical modeling in the context of modern biological problems. We present illustrative examples from this curriculum that highlight the ways in which three heuristics—instructor role-modeling, holding students to scientific norms, and providing students with opportunities to practice these norms—consistently supported learning across the curriculum. We present a more detailed comparison of two different curricular modules and explain how differences in student authority, problem structure, and access to resources contributed to differences in productive engagement by students in these modules. We hope that our analysis will help practitioners think in more concrete terms about how to achieve the goals set forth by BIO2010. PMID:20810958

There is now compelling evidence that motor imagery (MI) promotes motor learning. While MI has been shown to influence the early stages of the learning process, recent data revealed that sleep also contributes to the consolidation of the memory trace. How such "online" and "offline" processes take place and how they interact to impact the neural underpinnings of movements has received little attention. The aim of the present review is twofold: (i) providing an overview of recent applied and fundamental studies investigating the effects of MI practice (MIP) on motor learning; and (ii) detangling applied and fundamental findings in support of a sleep contribution to motor consolidation after MIP. We conclude with an integrative approach of online and offline learning resulting from intense MIP in healthy participants, and underline research avenues in the motor learning/clinical domains.

Defining and Leveraging Game Qualities for Serious Games

Martin, Michael W.; Shen, Yuzhong

2011-01-01

Serious games can and should leverage the unique qualities of video games to effectively deliver educational experiences for the learners. However, leveraging these qualities is incumbent upon understanding what these unique 'game' qualities are , and how they can facilitate the learning process. This paper presents an examination of the meaning of the term 'game' . as it applies to both serious games and digital entertainment games. Through the examination of counter examples, we derive three game characteristics; games are self contained, provide a variety of meaningful choices, and are intrinsically compelling. We also discuss the theoretical educational foundations which support the application of these 'game qualities' to educational endeavors. This paper concludes with a presentation of results achieved through the application of these qualities and the applicable educational theories to teach learners about the periodic table of elements via a serious game developed by the authors.

Social work and adverse childhood experiences research: implications for practice and health policy.

2014-01-01

Medical research on "adverse childhood experiences" (ACEs) reveals a compelling relationship between the extent of childhood adversity, adult health risk behaviors, and principal causes of death in the United States. This article provides a selective review of the ACE Study and related social science research to describe how effective social work practice that prevents ACEs and mobilizes resilience and recovery from childhood adversity could support the achievement of national health policy goals. This article applies a biopsychosocial perspective, with an emphasis on mind-body coping processes to demonstrate that social work responses to adverse childhood experiences may contribute to improvement in overall health. Consistent with this framework, the article sets forth prevention and intervention response strategies with individuals, families, communities, and the larger society. Economic research on human capital development is reviewed that suggests significant cost savings may result from effective implementation of these strategies.

The phenomenon of negative remanent magnetization (NRM) has been observed experimentally in a number of heterogeneous magnetic systems and has been considered anomalous. The existence of NRM in homogenous magnetic materials is still in debate, mainly due to the lack of compelling support from experimental data and a convincing theoretical explanation for its thermodynamic validation. Here we resolve the long-existing controversy by presenting experimental evidence and physical justification that NRM is real in a prototype homogeneous ferromagnetic nanoparticle, an europium sulfide nanoparticle. We provide novel insights into major and minor hysteresis behavior that illuminate the true nature of the observed inverted hysteresis and validate its thermodynamic permissibility and, for the first time, present counterintuitive magnetic aftereffect behavior that is consistent with the mechanism of magnetization reversal, possessing unique capability to identify NRM. The origin and conditions of NRM are explained quantitatively via a wasp-waist model, in combination of energy calculations. PMID:25183061

As with human beings, dogs suffer from the consequences of cancer. We investigated the potential of a formulation comprised of resveratrol, ellagic acid, genistein, curcumin and quercetin to modulate biomarkers indicative of disease prevention. Dog biscuits were evaluated for palatability and ability to deliver the chemopreventive agents. The extent of endogenous DNA damage in peripheral blood lymphocytes from dogs given the dietary supplement or placebo showed no change. However, H2O2-inducible DNA damage was significantly decreased after consumption of the supplement. The expression of 11 of 84 genes related to oxidative stress was altered. Hematological parameters remained in the reference range. The concept of chemoprevention for the explicit benefit of the canine is compelling since dogs are an important part of our culture. Our results establish a proof-of-principle and provide a framework for improving the health and well-being of “man’s best friend”. PMID:27216246

Leader-member exchange (LMX) and innovation climate: the role of LMX differentiation.

PubMed

Tordera, Núria; González-Romá, Vicente

2013-01-01

Leader-member Exchange (LMX) theory has been shown to be one of the most compelling theories for understanding the effects of leadership on organizational behavior. This theory proposes that leaders establish differentiated relationships with each of their subordinates according to the exchanges produced between them. Recently, the concept of LMX differentiation has been introduced into the theory to extend research from the dyadic to the group level. The present paper uses a longitudinal design to analyze the moderator role of LMX differentiation in the relationship between mean LMX and innovation climate in a sample of 24 healthcare teams. The results showed no direct effects of mean LMX on changes in innovation climate over time. However, they provide support for the moderator effect of LMX differentiation in this relationship, as it was stronger when LMX differentiation was low than when it was high.

Procedures from the healthcare domain involve highly critical actions as they may pose a risk for patients' life. Therefore, a large effort is devoted to the standardization in clinical praxis and to the control of quality for these protocols in order to minimize hazards. In this line, this work is compelled to provide an ICT-based support to carry out these controls in a simple and effective manner. Using a methodology based on HACCP and taking advantage of Semantic tools, a holistic platform of services for traceability and control of processes has been designed and implemented. The applied paradigm is based on the use of Control Points as singular points to generate traces using observations and measures relevant for the processes considered. Based on those, it is possible to offer services for advanced querying and knowledge inference. The local deployment just requires regular mobile phones or tablets making this solution cost-effective and easily replicable.

Geochemical evidence for combustion of hydrocarbons during the K-T impact event

Belcher, Claire M.; Finch, Paul; Collinson, Margaret E.; Scott, Andrew C.; Grassineau, Nathalie V.

2009-01-01

It has been proposed that extensive wildfires occurred after the Cretaceous–Tertiary (K-T) impact event. An abundance of soot and pyrosynthetic polycyclic aromatic hydrocarbons (pPAHs) in marine K-T boundary impact rocks (BIRs) have been considered support for this hypothesis. However, nonmarine K-T BIRs, from across North America, contain only rare occurrences of charcoal yet abundant noncharred plant remains. pPAHs and soot can be formed from a variety of sources, including partial combustion of vegetation and hydrocarbons whereby modern pPAH signatures are traceable to their source. We present results from multiple nonmarine K-T boundary sites from North America and reveal that the K-T BIRs have a pPAH signature consistent with the combustion of hydrocarbons and not living plant biomass, providing further evidence against K-T wildfires and compelling evidence that a significant volume of hydrocarbons was combusted during the K-T impact event.

Association and haplotype analysis of the insulin-degrading enzyme (IDE) gene, a strong positional and biological candidate for type 2 diabetes susceptibility.

2003-05-01

The gene for insulin-degrading enzyme (IDE) represents a strong positional and biological candidate for type 2 diabetes susceptibility. IDE maps to chromosome 10q23.3, a region linked to diabetes in several populations; the rat homolog has been directly implicated in diabetes susceptibility; and known functions of IDE support an important role in glucose homeostasis. We sought evidence for association between IDE variation and diabetes by mutation screening, defining local haplotype structure, and genotyping variants delineating common haplotypic diversity. An initial case-control analysis (628 diabetic probands from multiplex sibships and 604 control subjects) found no haplotypic associations, although one variant (IDE2, -179T-->C) showed modest association with diabetes (odds ratio [OR]1.25, P = 0.03). Linkage partitioning analyses failed to support this association, but provided borderline evidence for a different variant (IDE10, IVS20-405A-->G) (P = 0.06). Neither variant was associated with diabetes when replication was sought in 377 early onset diabetic subjects and 825 control subjects, though combined analysis of all typed cohorts indicated a nominally significant effect at IDE2 (OR 1.21 [1.04-1.40], P = 0.013). In the absence of convincing support for this association from linkage partitioning or analyses of continuous measures of glycemia, we conclude that analysis of over 2,400 samples provides no compelling evidence that variation in IDE contributes to diabetes susceptibility in humans.

Chronic disease management: it's time for transformational change!

PubMed

Muttitt, Sarah C; Alvarez, Richard C

2007-01-01

The authors of the lead essay present a compelling case for the development and implementation of a national strategy on chronic disease prevention and management (CDPM). The literature demonstrates that the Chronic Care Model can improve quality and reduce costs. Substantial evidence supports the role of health information technologies such as electronic health records (EHRs) in achieving these goals. However, an interoperable pan-Canadian health infostructure does not exist; funding is required to establish this across the continuum of care. An investment of $350 per capita would provide a robust health technology platform to support a national CDPM strategy. Such an investment would deliver annual benefits of $6-$7.6 billion; this could be leveraged to support national healthcare priorities such as CDPM. EHRs will improve decisions about care, reduce system errors and increase efficiency. They will also improve our ability to measure, assess and manage care. We cannot run a high-performing health system without sound data. This was a key step to enabling progress on wait times management. Leadership is required if a national CDPM strategy is to become reality. The authors made a convincing case for the development of a national strategy; we need to turn their words into actionable events to gain necessary momentum.

Engineering long term clinical success of advanced ceramic prostheses.

PubMed

Rekow, Dianne; Thompson, Van P

2007-01-01

Biocompatability and, in some applications, esthetics make all-ceramic prostheses compelling choices but despite significant improvements in materials properties and toughening mechanisms, these still have significant failure rates. Factors that contribute to the degradation in strength and survival include material selection and prosthesis design which set the upper limit for performance. However, fabrication operations introduce damage that can be exacerbated by environmental conditions and clinical function. Using all-ceramic dental crowns as an example, experimentally derived models provide insight into the relationships between materials properties and initial critical loads to failure. Analysis of fabrication operations suggests strategies to minimize damage. Environmental conditions can create viscoplastic flow of supporting components which can contribute additional stress within the prosthesis. Fatigue is a particularly challenging problem, not only providing the energy to propagate existing damage but, when combined with the wet environment, can create new damage modes. While much is known, the influence of these new damage modes has not been completely elucidated. The role of complex prosthesis geometry and its interaction with other factors on damage initiation and propagation has yet to be well characterized.

Evolution of a Materials Data Infrastructure

NASA Astrophysics Data System (ADS)

Warren, James A.; Ward, Charles H.

2018-06-01

The field of materials science and engineering is writing a new chapter in its evolution, one of digitally empowered materials discovery, development, and deployment. The 2008 Integrated Computational Materials Engineering (ICME) study report helped usher in this paradigm shift, making a compelling case and strong recommendations for an infrastructure supporting ICME that would enable access to precompetitive materials data for both scientific and engineering applications. With the launch of the Materials Genome Initiative in 2011, which drew substantial inspiration from the ICME study, digital data was highlighted as a core component of a Materials Innovation Infrastructure, along with experimental and computational tools. Over the past 10 years, our understanding of what it takes to provide accessible materials data has matured and rapid progress has been made in establishing a Materials Data Infrastructure (MDI). We are learning that the MDI is essential to eliminating the seams between experiment and computation by providing a means for them to connect effortlessly. Additionally, the MDI is becoming an enabler, allowing materials engineering to tie into a much broader model-based engineering enterprise for product design.

Helium isotopes at Rungwe Volcanic Province, Tanzania, and the origin of East African Plateaux

NASA Astrophysics Data System (ADS)

Hilton, D. R.; Halldórsson, S. A.; Barry, P. H.; Fischer, T. P.; de Moor, J. M.; Ramirez, C. J.; Mangasini, F.; Scarsi, P.

2011-11-01

We report helium isotope ratios (3He/4He) of lavas and tephra of the Rungwe Volcanic Province (RVP) in southern Tanzania. Values as high as 15RA (RA = air 3He/4He) far exceed typical upper mantle values, and are the first observation of plume-like ratios south of the Turkana Depression which separates the topographic highs of the Ethiopia and Kenya domes. The African Superplume - a tilted low-velocity seismic anomaly extending to the core-mantle boundary beneath southern Africa - is the likely source of these high 3He/4He ratios. High 3He/4He ratios at RVP together with similarly-high values along the Main Ethiopian Rift and in Afar provide compelling evidence that the African Superplume is a feature that extends through the 670-km seismic discontinuity and provides dynamic support - either as a single plume or via multiple upwellings - for the two main topographic features of the East Africa Rift System as well as heat and mass to drive continuing rift-related magmatism.

Faculty career flexibility: Why we need it and how best to achieve it

NASA Astrophysics Data System (ADS)

Quinn, Kate

2010-02-01

Research conducted over the last decade provides compelling evidence that higher education institutions have a strong business case for providing flexibility for their tenure-track and tenured faculty. Flexibility constitutes an effective tool for recruiting and retaining talented faculty. Career flexibility is especially critical to retaining some of the most qualified female PhDs in academic science, engineering, and mathematics. Acquiring the best talent is essential to an institution's ability to achieve excellence and maintain its competitive advantage in a global environment. In an effort to increase the flexibility of faculty careers, the American Council on Education partnered with the Alfred P. Sloan Foundation to create the Award for Faculty Career Flexibility. This presentation will address the origins of the award and share findings from the awards process. Fairly simple and cost effective strategies have been successful in accelerating the cultural change necessary to increase the flexibility of faculty careers. This presentation shares these strategies in addition to information about the types of policies and practices being adopted to support faculty work-life balance through career flexibility. )

Preparing Science Teachers for the future

Stein, Fredrick

2002-04-01

What will teachers need in the future to be successful? What will "successful" mean in the future? Are the teaching approaches learned 40 years ago still relevant for tomorrow's classrooms? Will technology really change the way physics is taught (K-16)? Will we close the performance gap between students of differing ethnicity? Are schools of education rising to the challenge to answer these questions? Can college and university physics departments rise to the challenge of presenting physics to all students in an engaging manner? What can the APS, in partnership with AAPT and AIP, do to find the answers and provide strategies to improve the science preparation of future teachers? PhysTEC aims to help physics and education faculty work together to provide an education for future teachers that emphasizes a student-centered, hands-on, inquiry-based approach to learning science. The compelling evidence produced from Physics Education Research warrants this approach. A National Science Foundation grant of 5.76 million and a 498 thousand grant from the Fund for the Improvement of Postsecondary Education support PhysTEC, its partners and activities. http://www.phystec.org/

The Evolution of System Safety at NASA

NASA Technical Reports Server (NTRS)

Dezfuli, Homayoon; Everett, Chris; Groen, Frank

2014-01-01

The NASA system safety framework is in the process of change, motivated by the desire to promote an objectives-driven approach to system safety that explicitly focuses system safety efforts on system-level safety performance, and serves to unify, in a purposeful manner, safety-related activities that otherwise might be done in a way that results in gaps, redundancies, or unnecessary work. An objectives-driven approach to system safety affords more flexibility to determine, on a system-specific basis, the means by which adequate safety is achieved and verified. Such flexibility and efficiency is becoming increasingly important in the face of evolving engineering modalities and acquisition models, where, for example, NASA will increasingly rely on commercial providers for transportation services to low-earth orbit. A key element of this objectives-driven approach is the use of the risk-informed safety case (RISC): a structured argument, supported by a body of evidence, that provides a compelling, comprehensible and valid case that a system is or will be adequately safe for a given application in a given environment. The RISC addresses each of the objectives defined for the system, providing a rational basis for making informed risk acceptance decisions at relevant decision points in the system life cycle.

Transcriptome Analysis of Manganese-deficient Chlamydomonas reinhardtii Provides Insight on the Chlorophyll Biosynthesis Pathway

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lockhart, Ainsley; Zvenigorodsky, Natasha; Pedraza, Mary Ann

2011-08-11

The biosynthesis of chlorophyll and other tetrapyrroles is a vital but poorly understood process. Recent genomic advances with the unicellular green algae Chlamydomonas reinhardtii have created opportunity to more closely examine the mechanisms of the chlorophyll biosynthesis pathway via transcriptome analysis. Manganese is a nutrient of interest for complex reactions because of its multiple stable oxidation states and role in molecular oxygen coordination. C. reinhardtii was cultured in Manganese-deplete Tris-acetate-phosphate (TAP) media for 24 hours and used to create cDNA libraries for sequencing using Illumina TruSeq technology. Transcriptome analysis provided intriguing insight on possible regulatory mechanisms in the pathway. Evidencemore » supports similarities of GTR (Glutamyl-tRNA synthase) to its Chlorella vulgaris homolog in terms of Mn requirements. Data was also suggestive of Mn-related compensatory up-regulation for pathway proteins CHLH1 (Manganese Chelatase), GUN4 (Magnesium chelatase activating protein), and POR1 (Light-dependent protochlorophyllide reductase). Intriguingly, data suggests possible reciprocal expression of oxygen dependent CPX1 (coproporphyrinogen III oxidase) and oxygen independent CPX2. Further analysis using RT-PCR could provide compelling evidence for several novel regulatory mechanisms in the chlorophyll biosynthesis pathway.« less

DNA linkage studies of degenerative retinal diseases.

PubMed

Daiger, S P; Heckenlively, J R; Lewis, R A; Pelias, M Z

1987-01-01

DNA linkage studies of human genetic diseases have led to rapid characterization of a number of otherwise intractable disease loci. Detection of a linked DNA marker, the first step in "reverse genetics", has permitted cloning of the genes for Duchenne muscular dystrophy, retinoblastoma and chronic granulomatosis disease, among others. Thus, the case for applying these techniques to retinitis pigmentosa and related diseases, and the urgency in capitalizing on molecular developments, is justified and compelling. The first major success regarding RP was in demonstrating linkage of the DNA marker DXS7 (L1.28) to XRP. For autosomal forms of the disease, conventional linkage studies have provided tentative evidence for linkage of ADRP to the Rh blood group on chromosome lp and for linkage of Usher's syndrome to Gc and 4q. These provisional assignments are, at least, an important starting point for DNA analysis. The Support Program for DNA Linkage Studies of Degenerative Retinal Diseases was established to provide access for the scientific community to appropriate families, using the resources of the Human Genetic Mutant Cell Repository to prepare, store and distribute lymphoblast lines. To date, two extensive, well-characterized families are included in the program: the autosomal dominant RP family UCLA-RP01, and the Usher's syndrome families LSU-US01. It is highly likely that rapid progress will be made in mapping and characterizing the inherited retinal dystrophies. We believe the support program will facilitate this progress.

Overtreatment of displaced midshaft clavicle fractures

2016-01-01

Background and purpose The best treatment for displaced clavicle fractures has been debated for decades. Operative treatment has become more common. However, several randomized trials comparing non-operative and operative treatment have not shown any compelling evidence in favor of surgery. We identified the preferred treatment of displaced midshaft clavicle fractures at public hospitals in 3 countries in Scandinavia. Patients and methods A purpose-made multiple-choice questionnaire in English was sent to all public hospitals in Denmark, Sweden, and Finland. This was addressed to the orthopedic surgeon responsible for treatment of clavicle fractures, and completed questionnaires were obtained from 85 of 118 hospitals. Results In the 3 countries, 69 of the 85 hospitals that responded would treat displaced clavicle fractures operatively. Clear criteria for treatment allocation were used at 58 of the hospitals, with the remaining 27 using individual assessment in collaboration with the patient. Precontoured locking plates were mostly used, placed either superiorly (64/85) or anteriorly (10/85). Interpretation Displaced midshaft clavicle fractures are mainly treated operatively in Sweden, Denmark, and Finland. This treatment is not supported by compelling evidence. PMID:27225678

Psychological responses to the proximity of climate change

NASA Astrophysics Data System (ADS)

Brügger, Adrian; Dessai, Suraje; Devine-Wright, Patrick; Morton, Thomas A.; Pidgeon, Nicholas F.

2015-12-01

A frequent suggestion to increase individuals' willingness to take action on climate change and to support relevant policies is to highlight its proximal consequences, that is, those that are close in space and time. But previous studies that have tested this proximizing approach have not revealed the expected positive effects on individual action and support for addressing climate change. We present three lines of psychological reasoning that provide compelling arguments as to why highlighting proximal impacts of climate change might not be as effective a way to increase individual mitigation and adaptation efforts as is often assumed. Our contextualization of the proximizing approach within established psychological research suggests that, depending on the particular theoretical perspective one takes on this issue, and on specific individual characteristics suggested by these perspectives, proximizing can bring about the intended positive effects, can have no (visible) effect or can even backfire. Thus, the effects of proximizing are much more complex than is commonly assumed. Revealing this complexity contributes to a refined theoretical understanding of the role that psychological distance plays in the context of climate change and opens up further avenues for future research and for interventions.

Injectable Polyurethane Composite Scaffolds Delay Wound Contraction and Support Cellular Infiltration and Remodeling in Rat Excisional Wounds

PubMed Central

Adolph, Elizabeth J.; Hafeman, Andrea E.; Davidson, Jeffrey M.; Nanney, Lillian B.; Guelcher, Scott A.

2011-01-01

Injectable scaffolds present compelling opportunities for wound repair and regeneration due to their ability to fill irregularly shaped defects and deliver biologics such as growth factors. In this study, we investigated the properties of injectable polyurethane biocomposite scaffolds and their application in cutaneous wound repair using a rat excisional model. The scaffolds have a minimal reaction exotherm and clinically relevant working and setting times. Moreover, the biocomposites have mechanical and thermal properties consistent with rubbery elastomers. In the rat excisional wound model, injection of settable biocomposite scaffolds stented the wounds at early time points, resulting in a regenerative rather than a scarring phenotype at later time points. Measurements of wound width and thickness revealed that the treated wounds were less contracted at day 7 compared to blank wounds. Analysis of cell proliferation and apoptosis showed that the scaffolds were biocompatible and supported tissue ingrowth. Myofibroblast formation and collagen fiber organization provided evidence that the scaffolds have a positive effect on extracellular matrix remodeling by disrupting the formation of an aligned matrix under elevated tension. In summary, we have developed an injectable biodegradable polyurethane biocomposite scaffold that enhances cutaneous wound healing in a rat model. PMID:22105887

RocketCam systems for providing situational awareness on rockets, spacecraft, and other remote platforms

NASA Astrophysics Data System (ADS)

Ridenoure, Rex

2004-09-01

Space-borne imaging systems derived from commercial technology have been successfully employed on launch vehicles for several years. Since 1997, over sixty such imagers - all in the product family called RocketCamTM - have operated successfully on 29 launches involving most U.S. launch systems. During this time, these inexpensive systems have demonstrated their utility in engineering analysis of liftoff and ascent events, booster performance, separation events and payload separation operations, and have also been employed to support and document related ground-based engineering tests. Such views from various vantage points provide not only visualization of key events but stunning and extremely positive public relations video content. Near-term applications include capturing key events on Earth-orbiting spacecraft and related proximity operations. This paper examines the history to date of RocketCams on expendable and manned launch vehicles, assesses their current utility on rockets, spacecraft and other aerospace vehicles (e.g., UAVs), and provides guidance for their use in selected defense and security applications. Broad use of RocketCams on defense and security projects will provide critical engineering data for developmental efforts, a large database of in-situ measurements onboard and around aerospace vehicles and platforms, compelling public relations content, and new diagnostic information for systems designers and failure-review panels alike.

Morais, Daniel Kumazawa; Cuadros-Orellana, Sara; Pais, Fabiano Sviatopolk-Mirsky; Medeiros, Julliane Dutra; Geraldo, Juliana Assis; Gilbert, Jack; Volpini, Angela Cristina; Fernandes, Gabriel Rocha

2016-01-01

Background In early 2015, a ZIKA Virus (ZIKV) infection outbreak was recognized in northeast Brazil, where concerns over its possible links with infant microcephaly have been discussed. Providing a causal link between ZIKV infection and birth defects is still a challenge. MicroRNAs (miRNAs) are small noncoding RNAs (sncRNAs) that regulate post-transcriptional gene expression by translational repression, and play important roles in viral pathogenesis and brain development. The potential for flavivirus-mediated miRNA signalling dysfunction in brain-tissue development provides a compelling hypothesis to test the perceived link between ZIKV and microcephaly. Methodology/Principal Findings Here, we applied in silico analyses to provide novel insights to understand how Congenital ZIKA Syndrome symptoms may be related to an imbalance in miRNAs function. Moreover, following World Health Organization (WHO) recommendations, we have assembled a database to help target investigations of the possible relationship between ZIKV symptoms and miRNA-mediated human gene expression. Conclusions/Significance We have computationally predicted both miRNAs encoded by ZIKV able to target genes in the human genome and cellular (human) miRNAs capable of interacting with ZIKV genomes. Our results represent a step forward in the ZIKV studies, providing new insights to support research in this field and identify potential targets for therapy. PMID:27332714

Resolving the biophysics of axon transmembrane polarization in a single closed-form description

DOE Office of Scientific and Technical Information (OSTI.GOV)

Melendy, Robert F., E-mail: rfmelendy@liberty.edu

2015-12-28

When a depolarizing event occurs across a cell membrane there is a remarkable change in its electrical properties. A complete depolarization event produces a considerably rapid increase in voltage that propagates longitudinally along the axon and is accompanied by changes in axial conductance. A dynamically changing magnetic field is associated with the passage of the action potential down the axon. Over 75 years of research has gone into the quantification of this phenomenon. To date, no unified model exist that resolves transmembrane polarization in a closed-form description. Here, a simple but formative description of propagated signaling phenomena in the membranemore » of an axon is presented in closed-form. The focus is on using both biophysics and mathematical methods for elucidating the fundamental mechanisms governing transmembrane polarization. The results presented demonstrate how to resolve electromagnetic and thermodynamic factors that govern transmembrane potential. Computational results are supported by well-established quantitative descriptions of propagated signaling phenomena in the membrane of an axon. The findings demonstrate how intracellular conductance, the thermodynamics of magnetization, and current modulation function together in generating an action potential in a unified closed-form description. The work presented in this paper provides compelling evidence that three basic factors contribute to the propagated signaling in the membrane of an axon. It is anticipated this work will compel those in biophysics, physical biology, and in the computational neurosciences to probe deeper into the classical and quantum features of membrane magnetization and signaling. It is hoped that subsequent investigations of this sort will be advanced by the computational features of this model without having to resort to numerical methods of analysis.« less

Evolving from Planning and Scheduling to Real-Time Operations Support: Design Challenges

NASA Technical Reports Server (NTRS)

Marquez, Jessica J.; Ludowise, Melissa; McCurdy, Michael; Li, Jack

2010-01-01

Versions of Scheduling and Planning Interface for Exploration (SPIFe) have supported a variety of mission operations across NASA. This software tool has evolved and matured over several years, assisting planners who develop intricate schedules. While initially conceived for surface Mars missions, SPIFe has been deployed in other domains, where people rather than robotic explorers, execute plans. As a result, a diverse set of end-users has compelled growth in a new direction: supporting real-time operations. This paper describes the new needs and challenges that accompany this development. Among the key features that have been built for SPIFe are current time indicators integrated into the interface and timeline, as well as other plan attributes that enable execution of scheduled activities. Field tests include mission support for the Lunar CRater Observation and Sensing Satellite (LCROSS), NASA Extreme Environment Mission Operations (NEEMO) and Desert Research and Technology Studies (DRATS) campaigns.

‘Betty’ the New Caledonian crow astonished the world when she ‘spontaneously’ bent straight pieces of garden wire into hooked foraging tools. Recent field experiments have revealed that tool bending is part of the species' natural behavioural repertoire, providing important context for interpreting Betty's iconic wire-bending feat. More generally, this discovery provides a compelling illustration of how natural history observations can inform laboratory-based research into the cognitive capacities of non-human animals.

Evaluation of Wearable Haptic Systems for the Fingers in Augmented Reality Applications.

Maisto, Maurizio; Pacchierotti, Claudio; Chinello, Francesco; Salvietti, Gionata; De Luca, Alessandro; Prattichizzo, Domenico

2017-01-01

Although Augmented Reality (AR) has been around for almost five decades, only recently we have witnessed AR systems and applications entering in our everyday life. Representative examples of this technological revolution are the smartphone games "Pokémon GO" and "Ingress" or the Google Translate real-time sign interpretation app. Even if AR applications are already quite compelling and widespread, users are still not able to physically interact with the computer-generated reality. In this respect, wearable haptics can provide the compelling illusion of touching the superimposed virtual objects without constraining the motion or the workspace of the user. In this paper, we present the experimental evaluation of two wearable haptic interfaces for the fingers in three AR scenarios, enrolling 38 participants. In the first experiment, subjects were requested to write on a virtual board using a real chalk. The haptic devices provided the interaction forces between the chalk and the board. In the second experiment, subjects were asked to pick and place virtual and real objects. The haptic devices provided the interaction forces due to the weight of the virtual objects. In the third experiment, subjects were asked to balance a virtual sphere on a real cardboard. The haptic devices provided the interaction forces due to the weight of the virtual sphere rolling on the cardboard. Providing haptic feedback through the considered wearable device significantly improved the performance of all the considered tasks. Moreover, subjects significantly preferred conditions providing wearable haptic feedback.

Adolescents’ impressions of antismoking media literacy education: qualitative results from a randomized controlled trial

Primack, Brian A.; Fine, Danielle; Yang, Christopher K.; Wickett, Dustin; Zickmund, Susan

2009-01-01

Although media literacy represents an innovative venue for school-based antismoking programming, studies have not systematically compared student impressions of these and traditional programs. This study utilized data from a randomized trial comparing these two types of programs. After each program, students responded to three open-ended questions related to their assigned curriculum. Two coders, blinded to student assignments, independently coded these data. Coders had strong inter-rater agreement (kappa = 0.77). Our primary measures were spontaneously noted overall assessment, enjoyment/interest and the likelihood of changing smoking behavior. Of the 531 participants, 255 (48.0%) were randomized to the intervention (media literacy) group. Intervention participants had more net positive responses [rate ratio (RR) = 1.27, 95% confidence interval (CI) = 1.05, 1.54], more responses rating the program as compelling (RR = 1.63, 95% CI = 1.16, 2.29) and fewer responses rating the program as non-compelling (RR = 0.62, 95% CI = 0.39, 0.97). However, the intervention group was not more likely to suggest that the curriculum was likely to change behavior positively (RR = 0.57, 95% CI = 0.30, 1.06). Findings suggest that although media literacy provides a compelling format for the delivery of antitobacco programming, integration of components of traditional programming may help media literacy programs achieve maximal efficacy.

The Contribution of Network Organization and Integration to the Development of Cognitive Control

2015-01-01

Abstract Cognitive control, which continues to mature throughout adolescence, is supported by the ability for well-defined organized brain networks to flexibly integrate information. However, the development of intrinsic brain network organization and its relationship to observed improvements in cognitive control are not well understood. In the present study, we used resting state functional magnetic resonance imaging (RS-fMRI), graph theory, the antisaccade task, and rigorous head motion control to characterize and relate developmental changes in network organization, connectivity strength, and integration to inhibitory control development. Subjects were 192 10–26-y-olds who were imaged during 5 min of rest. In contrast to initial studies, our results indicate that network organization is stable throughout adolescence. However, cross-network integration, predominantly of the cingulo-opercular/salience network, increased with age. Importantly, this increased integration of the cingulo-opercular/salience network significantly moderated the robust effect of age on the latency to initiate a correct inhibitory control response. These results provide compelling evidence that the transition to adult-level inhibitory control is dependent upon the refinement and strengthening of integration between specialized networks. Our findings support a novel, two-stage model of neural development, in which networks stabilize prior to adolescence and subsequently increase their integration to support the cross-domain incorporation of information processing critical for mature cognitive control.

Elevated olivine weathering rates and sulfate formation at cryogenic temperatures on Mars.

PubMed

Niles, Paul B; Michalski, Joseph; Ming, Douglas W; Golden, D C

2017-10-17

Large Hesperian-aged (~3.7 Ga) layered deposits of sulfate-rich sediments in the equatorial regions of Mars have been suggested to be evidence for ephemeral playa environments. But early Mars may not have been warm enough to support conditions similar to what occurs in arid environments on Earth. Instead cold, icy environments may have been widespread. Under cryogenic conditions sulfate formation might be blocked, since kinetics of silicate weathering are typically strongly retarded at temperatures well below 0 °C. But cryo-concentration of acidic solutions may counteract the slow kinetics. Here we show that cryo-concentrated acidic brines rapidly chemically weather olivine minerals and form sulfate minerals at temperatures as low as -60 °C. These experimental results demonstrate the viability of sulfate formation under current Martian conditions, even in the polar regions. An ice-hosted sedimentation and weathering model may provide a compelling description of the origin of large Hesperian-aged layered sulfate deposits on Mars.

An applications-oriented approach to the development of virtual environments

NASA Technical Reports Server (NTRS)

Crowe, Michael X.

1994-01-01

The field of Virtual Reality (VR) is diverse, ranging in scope from research into fundamental enabling technologies to the building of full-scale entertainment facilities. However, the concept of virtual reality means many things to many people. Ideally, a definition of VR should derive from how it can provide solutions to existing challenges in building advanced human computer interfaces. The measure of success for VR lies in its ability to enhance the assimilation of complex information, whether to aid in difficult decision making processes, or to recreate real experiences in a compelling way. This philosophy is described using an example from a VR-based advertising project. The common and unique elements of this example are explained, though the fundamental development process is the same for all virtual environments that support information transfer. In short, this development approach is an applications oriented approach that begins by establishing and prioritizing user requirements and seeks to add value to the information transfer process through the appropriate use of VR technology.

A critical review of recent biological research on human sexual orientation.

PubMed

Mustanski, Brian S; Chivers, Meredith L; Bailey, J Michael

2002-01-01

This article provides a comprehensive review and critique of biological research on sexual orientation published over the last decade. We cover research investigating (a) the neurohormonal theory of sexual orientation (psychoneuroendocrinology, prenatal stress, cerebral asymmetry, neuroanatomy, otoacoustic emissions, anthropometrics), (b) genetic influences, (c) fraternal birth-order effects, and (d) a putative role for developmental instability. Despite inconsistent results across both studies and traits, some support for the neurohormonal theory is garnered, but mostly in men. Genetic research using family and twin methodologies has produced consistent evidence that genes influence sexual orientation, but molecular research has not yet produced compelling evidence for specific genes. Although it has been well established that older brothers increase the odds of homosexuality in men, the route by which this occurs has not been resolved. We conclude with an examination of the limitations of biological research on sexual orientation, including measurement issues (paper and pencil, cognitive, and psychophysiological), and lack of research on women.

How does brain insulin resistance develop in Alzheimer's disease?

PubMed

De Felice, Fernanda G; Lourenco, Mychael V; Ferreira, Sergio T

2014-02-01

Compelling preclinical and clinical evidence supports a pathophysiological connection between Alzheimer's disease (AD) and diabetes. Altered metabolism, inflammation, and insulin resistance are key pathological features of both diseases. For many years, it was generally considered that the brain was insensitive to insulin, but it is now accepted that this hormone has central neuromodulatory functions, including roles in learning and memory, that are impaired in AD. However, until recently, the molecular mechanisms accounting for brain insulin resistance in AD have remained elusive. Here, we review recent evidence that sheds light on how brain insulin dysfunction is initiated at a molecular level and why abnormal insulin signaling culminates in synaptic failure and memory decline. We also discuss the cellular basis underlying the beneficial effects of stimulation of brain insulin signaling on cognition. Discoveries summarized here provide pathophysiological background for identification of novel molecular targets and for development of alternative therapeutic approaches in AD.

The design used a convenience sample of eight nurses with an average of 11 years of active and current experience as neonatal intensive care nurses. METHOD/DATA COLLECTION: Human rights were protected according to the institutional guidelines. Data collection included semi-structured, intensive face-to-face interviews, observation, and field notes. The interviews were tape recorded and transcribed. Collaizzi's (1978) interpretation method was used to interpret and analyze the data using significant statements, formulated meanings, and clustering. Each participant was allowed to review the typed interview as one means of credibility. Analysis of the described experiences revealed that nurses were able to identify enough satisfying situations that compelled them to continue working in the neonatal intensive care unit (NICU). These rewards included compensation, team spirit, support from physicians, and advocacy. Knowledge of the factors that contribute to nurses' job satisfaction can provide a useful framework to implement policies to improve working conditions for nurses.

UV/Visible Telescope with Hubble Disposal

Submission Overview: Our primary objective is to convey a sense of the significant advances possible in astrophysics investigations for major Cosmic Origins COR program goals with a 2.4m telescope asset outfitted with one or more advanced UV visible instruments. Several compelling science objectives were identified based on community meetings these science objectives drove the conceptual design of instruments studied by the COR Program Office during July September 2012. This RFI submission encapsulates the results of that study, and suggests that a more detailed look into the instrument suite should be conducted to prove viability and affordability to support the demonstrated scientific value. This study was conducted in the context of a larger effort to consider the options available for a mission to dispose safely of Hubble hence, the overall architecture considered for the mission we studied for the 2.4m telescope asset included resource sharing. This mitigates combined cost and risk and provides naturally for a continued US leadership role in astrophysics with an advanced, general-purpose UV visible space telescope.

Emerging Role of Spinal Dynorphin in Chronic Pain, a Therapeutic Perspective

2016-01-01

Notable findings point to the significance of the dynorphin peptide neurotransmitter in chronic pain. Spinal dynorphin neuropeptide levels are elevated during development of chronic pain. Importantly, knockout of the dynorphin gene prevents development of chronic pain in mice, but acute nociception is unaffected. Intrathecal (IT) administration of opioid and non-opioid dynorphin peptides initiate allodynia through a non-opioid receptor mechanism; furthermore, anti-dynorphin antibodies administered by the IT route attenuate chronic pain. Thus, this review presents the compelling evidence in the field supporting the role of dynorphin in facilitating the development of a persistent pain state. These observations raise the question of the control mechanisms responsible for the upregulation of spinal dynorphin leading to chronic pain development. Also, spinal dynorphin regulation of downstream signaling molecules may be implicated in hyperpathic states. Therapeutic strategies to reduce spinal dynorphin may provide a non-addictive approach to improve the devastating condition of chronic pain that occurs in numerous human diseases. PMID:26738478

Template to Perpetrate: An Update on Violence in Autism Spectrum Disorder

PubMed Central

Im, David S.

2016-01-01

Abstract Introduction For the past two decades, researchers have been using various approaches to investigate the relationship, if any, between autism spectrum disorder (ASD) and violence. The need to clarify that relationship was reinforced by the tragic mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, in December 2012 by an individual diagnosed with Asperger’s syndrome. The purpose of this article is (1) to provide an updated review of the literature on the association between ASD and violence, and (2) to examine implications for treating, and for preventing violence by, individuals with ASD. Method A review of all published literature regarding ASD and violence from 1943 to 2014 was conducted using electronic and paper searches. Results Although some case reports have suggested an increased violence risk in individuals with ASD compared to the general population, prevalence studies have provided no conclusive evidence to support this suggestion. Among individuals with ASD, however, generative (e.g., comorbid psychopathology, social-cognition deficits, emotion-regulation problems) and associational (e.g., younger age, Asperger’s syndrome diagnosis, repetitive behavior) risk factors have been identified or proposed for violent behavior. Conclusions While no conclusive evidence indicates that individuals with ASD are more violent than those without ASD, specific generative and associational risk factors may increase violence risk among individuals with ASD. Further research would help to clarify or confirm these findings, suggest potential directions for evaluation, treatment, and prevention, and potentially provide compelling empirical support for forensic testimony regarding defendants with ASD charged with violent crimes.

Engaging rural Australian communities in National Science Week helps increase visibility for women researchers

Desselle, Mathilde R.

2017-01-01

During a week-long celebration of science, run under the federally supported National Science Week umbrella, the Catch a Rising Star: women in Queensland research (CaRS) programme flew scientists who identify as women to nine regional and remote communities in the Australian State of Queensland. The aim of the project was twofold: first, to bring science to remote and regional communities in a large, economically diverse state; and second, to determine whether media and public engagement provides career advancement opportunities for women scientists. This paper focuses on the latter goal. The data show: (i) a substantial majority (greater than 80%) of researchers thought the training and experience provided by the programme would help develop her career as a research scientist in the future, (ii) the majority (65%) thought the programme would help relate her research to end users, industry partners or stakeholders in the future, and (iii) analytics can help create a compelling narrative around engagement metrics and help to quantify influence. During the week-long project, scientists reached 600 000 impressions on one social media platform (Twitter) using a program hashtag. The breadth and depth of the project outcomes indicate funding bodies and employers could use similar data as an informative source of metrics to support hiring and promotion decisions. Although this project focused on researchers who identify as women, the lessons learned are applicable to researchers representing a diverse range of backgrounds. Future surveys will help determine whether the CaRS programme provided long-term career advantages to participating scientists and communities. PMID:29134069

Selling a service: experiences of peer supporters while promoting exclusive infant feeding in three sites in South Africa.

Even though it has been shown that peer support to mothers at home helps to increase exclusive breastfeeding, little is known about the experiences of peer supporters themselves and what is required of them to fulfil their day-to-day tasks. Therefore, a community-based randomised control trial using trained "lay" women to support exclusive infant feeding at home was implemented in three different sites across South Africa. The aim of this paper is to describe the experiences of peer supporters who promote exclusive infant feeding. Three focus group discussions were held, in a language of their choice, with peer supporters. These meetings focused on how the peer educators utilised their time in the process of delivering the intervention. Data from the discussions were transcribed, with both verbatim and translated transcripts being used in the analysis. Unlike the services provided by mainstream health care, peer supporters had to market their services. They had to negotiate entry into the mother's home and then her life. Furthermore, they had to demonstrate competence and come across as professional and trustworthy. An HIV-positive mother's fear of being stigmatised posed an added burden - subsequent disclosure of her positive status would lead to an increased workload and emotional distress. Peer supporters spent most of their time in the field and had to learn the skill of self-management. Their support-base was enhanced when supervision focused on their working conditions as well as the delivery of their tasks. Despite this, they faced other insurmountable issues, such as mothers being compelled to offer their infants mixed feeding simultaneously due to normative practices and working in the fields postpartum. Designers of peer support interventions should consider the skills required for delivering health messages and the skills required for selling a service. Supportive supervision should be responsive both to the health care task and the challenges faced in the process of delivering it. NCT00297150.

Deehan, Edward C; Duar, Rebbeca M; Armet, Anissa M; Perez-Muñoz, Maria Elisa; Jin, Mingliang; Walter, Jens

2017-09-01

There is a clear association between the gastrointestinal (GI) microbiome and the development of chronic noncommunicable diseases, providing a rationale for the development of strategies that target the GI microbiota to improve human health. In this article, we discuss the potential of supplementing the human diet with nondigestible fermentable carbohydrates (NDFCs) to modulate the composition, structure, diversity, and metabolic potential of the GI microbiome in an attempt to prevent or treat human disease. The current concepts by which NDFCs can be administered to humans, including prebiotics, fermentable dietary fibers, and microbiota-accessible carbohydrates, as well as the mechanisms by which these carbohydrates exert their health benefits, are discussed. Epidemiological research presents compelling evidence for the health effects of NDFCs, with clinical studies providing further support for some of these benefits. However, rigorously designed human intervention studies with well-established clinical markers and microbial endpoints are still essential to establish (i) the clinical efficiency of specific NDFCs, (ii) the causal role of the GI microbiota in these effects, (iii) the underlying mechanisms involved, and (iv) the degree by which inter-individual differences between GI microbiomes influence these effects. Such studies would provide the mechanistic understanding needed for a systematic application of NDFCs to improve human health via GI microbiota modulation while also allowing the personalization of these dietary strategies.

Creating Conditions for Policy Change in National Parks: Contrasting Cases in Yellowstone and Yosemite

Public agencies face significant political obstacles when they try to change long-standing policies. This paper examines efforts by the U.S. National Park Service to change long-term policies in Yellowstone and Yosemite national parks. We argue that, to be successful, the agency and pro-change allies must expand the sphere of conflict to engage the support of the broader American public through positive framing, supportive science, compelling economic arguments, consistent goals, and the commitment of other institutional actors. We show that the agency is capable of creating these conditions, as in the reintroduction of wolves to Yellowstone, but we argue that this is not always the outcome, as in reducing automobile congestion in Yosemite Valley.

In this brief review we will discuss the reasoning and evolution of our current use of combined very high-fluence collagen crosslinking and laser in situ keratomileusis. Several presentations and pertinent publications are reviewed, along with the key steps of the enhanced LASIK procedure. Long term outcome data support the safety and efficacy of LASIK Xtra in stabilizing myopic but also hyperopic LASIK results. In conclusion, we have compelling evidence that LASIK Xtra is a safe and effective adjunct. PMID:23925331

Atropine has been used for more than a century to arrest myopia progression. Compelling evidence of its protective effect has been reported in well-designed clinical studies, mainly performed during the last two decades. However, its exact mechanism of action has not been determined. Experimental findings have shown that the mechanism is not related to accommodation, as was thought for decades. A review of the published literature revealed a significant amount of evidence supporting its safety and efficacy at a concentration of 1.0%, and at lower concentrations (as low as 0.01%).

Neural circuitry governing anxious individuals' mis-allocation of working memory to threat.

Stout, Daniel M; Shackman, Alexander J; Pedersen, Walker S; Miskovich, Tara A; Larson, Christine L

2017-08-18

Dispositional anxiety is a trait-like phenotype that confers increased risk for a range of debilitating neuropsychiatric disorders. Like many patients with anxiety disorders, individuals with elevated levels of dispositional anxiety are prone to intrusive and distressing thoughts in the absence of immediate threat. Recent electrophysiological research suggests that these symptoms are rooted in the mis-allocation of working memory (WM) resources to threat-related information. Here, functional MRI was used to identify the network of brain regions that support WM for faces and to quantify the allocation of neural resources to threat-related distracters in 81 young adults. Results revealed widespread evidence of mis-allocation. This was evident in both face-selective regions of the fusiform cortex and domain-general regions of the prefrontal and parietal cortices. This bias was exaggerated among individuals with a more anxious disposition. Mediation analyses provided compelling evidence that anxious individuals' tendency to mis-allocate WM resources to threat-related distracters is statistically explained by heightened amygdala reactivity. Collectively, these results provide a neurocognitive framework for understanding the pathways linking anxious phenotypes to the development of internalizing psychopathology and set the stage for developing improved intervention strategies.

Asthma affects 7.1 million children in the United States, disproportionately burdening African American and Latino children. Barriers to asthma control include insufficient patient education and fragmented care. Care coordination represents a compelling approach to improve quality of care and address disparities in asthma. The sites of The Merck Childhood Asthma Network Care Coordination Programs implemented different models of care coordination to suit specific settings-school district, clinic or health care system, and community-and organizational structures. A variety of qualitative data sources were analyzed to determine the role setting played in the manifestation of care coordination at each site. There were inherent strengths and challenges of implementing care coordination in each of the settings, and each site used unique strategies to deliver their programs. The relationship between the lead implementing unit and entities that provided (1) access to the priority population and (2) clinical services to program participants played a critical role in the structure of the programs. The level of support and infrastructure provided by these entities to the lead implementing unit influenced how participants were identified and how asthma care coordinators were integrated into the clinical care team. © 2015 Society for Public Health Education.

In-Vitro Induced Immunosuppression in a Rotary Cell Culture System

NASA Technical Reports Server (NTRS)

Grimm, Elizabeth A.

1998-01-01

The function of the innate immune system is to provide a first-line of defense against infectious organisms, via control of bacterial and viral growth using antigen nonspecific means. These nonspecific immune effectors include macrophages and Natural Killing (NK) cells, and certain cytokines elicited in response to "super antigens" on the infectious agents. This innate system usually keeps most infectious agents from rapidly growing while the adaptive immune system is generating a specific response complete with immunologic memory. Compelling evidence suggests that space flight results in various immunosuppressive effects, including reduced innate and adaptive immune responses. We were particularly concerned with reduced NK activity at landing, and have asked whether the microgravity component of space flight could be responsible for the previously observed NK defect. We have conclusively demonstrated that simulated microgravity as provided by the Synthecon bioreactors does not inhibit the NK function nor the IL-2 activation of lymphokine-activated killing (LAK). Interleukin-2 is the key cytokine responsible for activation of NK cells to express LAK, as well as to support differentiation of lymphocytes during adaptive immune responses. Therefore, we have disproved our original hypothesis based on poor NK in many of the astronauts upon landing.

Realigning government action with public health evidence: the legal and policy environment affecting sex work and HIV in Asia.

PubMed

Gruskin, Sofia; Pierce, Gretchen Williams; Ferguson, Laura

2014-01-01

The HIV epidemic has shed light on how government regulation of sex work directly affects the health and well-being of sex workers, their families and communities. A review of the public health evidence highlights the need for supportive legal and policy environments, yet criminalisation of sex work remains standard around the world. Emerging evidence, coupled with evolving political ideologies, is increasingly shaping legal environments that promote the rights and health of sex workers but even as new legislation is created, contradictions often exist with standing problematic legislation. As a region, Asia provides a compelling example in that progressive HIV policies often sit side by side with laws that criminalise sex work. Data from the 21 Asian countries reporting under the UN General Assembly Special Session on HIV in 2010 were analysed to provide evidence of how countries' approach to sex-work regulation might affect HIV-related outcomes. Attention to the links between law and HIV-related outcomes can aid governments to meet their international obligations and ensure appropriate legal environments that cultivate the safe and healthy development and expression of sexuality, ensure access to HIV and other related services and promote and protect human rights.

Social values and the corruption argument against financial incentives for healthy behaviour

PubMed Central

Brown, Rebecca C H

2017-01-01

Financial incentives may provide a way of reducing the burden of chronic diseases by motivating people to adopt healthy behaviours. While it is still uncertain how effective such incentives could be for promoting health, some argue that, even if effective, there are ethical objections that preclude their use. One such argument is made by Michael Sandel, who suggests that monetary transactions can have a corrupting effect on the norms and values that ordinarily regulate exchange and behaviour in previously non-monetised contexts. In this paper, I outline Sandel's corruption argument and consider its validity in the context of health incentives. I distinguish between two forms of corruption that are implied by Sandel's argument: efficiency corruption and value corruption. While Sandel's thought-provoking discussion provides a valuable contribution to debates about health policies generally and health incentives specifically, I suggest the force of his criticism of health incentives is limited: further empirical evidence and theoretical reasoning are required to support the suggestion that health incentives are an inappropriate tool for promoting health. While I do not find Sandel's corruption argument compelling, this only constitutes a partial defence of health incentives, since other criticisms relating to their use may prove more successful.

Hyperkalemia in the Hypertensive Patient.

PubMed

Lakkis, Jay Ian; Weir, Matthew R

2018-03-01

Hyperkalemia develops in a patient with systemic arterial hypertension (HTN) if one or more risk factors are present, namely chronic kidney disease (CKD) (especially severe stage 4-5 CKD), diabetes mellitus (DM), heart failure (HF), or pharmacological therapies that interfere with potassium homeostasis, mainly through renin-angiotensin-aldosterone inhibition (RAASi). Hyperkalemia is a considerable reason of morbidity (emergency department (ED) visits and hospitalizations) and portends a higher mortality risk in patients at risk; for instance, hyperkalemia increases the risk of mortality within 1 day of a hyperkalemic event. This review aims to identify the risk factors for high-serum potassium, highlight the risk versus benefit of RAASi in certain patient populations, and outline preventive as well as therapeutic strategies for hyperkalemia. A growing body of evidence supports the safety and efficacy of cation-exchange resins, patiromer, or sodium zirconium cyclosilicate, in patients with a compelling indication for RAASi, yet in whom such therapy was complicated by hyperkalemia, allowing these patients to benefit from continued RAASi therapy. In summary, novel cation exchange polymers present the clinician with a new and safe strategy to address hyperkalemia in patients with a compelling indication for ongoing RAASi therapy instead of withdrawal of such therapy.

Consequentialism, complacency, and slippery slope arguments.

PubMed

Oakley, Justin; Cocking, Dean

2005-01-01

The standard problem with many slippery slope arguments is that they fail to provide us with the necessary evidence to warrant our believing that the significantly morally worse circumstances they predict will in fact come about. As such these arguments have widely been criticised as 'scare-mongering'. Consequentialists have traditionally been at the forefront of such criticisms, demanding that we get serious about guiding our prescriptions for right action by a comprehensive appreciation of the empirical facts. This is not surprising, since consequentialism has traditionally been committed to the idea that right action be driven by empirical realities, and this hard-headed approach has been an especially notable feature of Australian consequentialism. But this apparent empirical hard-headedness is very selective. While consequentialists have understood their moral outlook and commitments as guided by a partnership with empirical science - most explicitly in their replies to the arguments of their detractors - some consequentialists have been remarkably complacent about providing empirical support for their own prescriptions. Our key example here is the consequentialist claim that our current practises of partiality in fact maximise the good, impartially conceived. This claim has invariably been made without compelling support for the large empirical claims upon which it rests, and so, like the speculative empirical hand-waving of weak slippery slope arguments, it seems similarly to be undermined. While these arguments have presented us with 'wishful thinking' rather than 'scare-mongering', we argue in this paper that their complacency in meeting the relevant empirical justificatory burden remains much the same.

Geographic Distribution of Disease Mutations in the Ashkenazi Jewish Population Supports Genetic Drift over Selection

2003-01-01

The presence of four lysosomal storage diseases (LSDs) at increased frequency in the Ashkenazi Jewish population has suggested to many the operation of natural selection (carrier advantage) as the driving force. We compare LSDs and nonlysosomal storage diseases (NLSDs) in terms of the number of mutations, allele-frequency distributions, and estimated coalescence dates of mutations. We also provide new data on the European geographic distribution, in the Ashkenazi population, of seven LSD and seven NLSD mutations. No differences in any of the distributions were observed between LSDs and NLSDs. Furthermore, no regular pattern of geographic distribution was observed for LSD versus NLSD mutations—with some being more common in central Europe and others being more common in eastern Europe, within each group. The most striking disparate pattern was the geographic distribution of the two primary Tay-Sachs disease mutations, with the first being more common in central Europe (and likely older) and the second being exclusive to eastern Europe (primarily Lithuania and Russia) (and likely much younger). The latter demonstrates a pattern similar to two other recently arisen Lithuanian mutations, those for torsion dystonia and familial hypercholesterolemia. These observations provide compelling support for random genetic drift (chance founder effects, one ∼11 centuries ago that affected all Ashkenazim and another ∼5 centuries ago that affected Lithuanians), rather than selection, as the primary determinant of disease mutations in the Ashkenazi population.

Airship Industry Study: In 2015, NASA Ames Research Center completed a study of the overall airship industry. The project called for a report that describes airship concepts proposed or projects initiated in recent years, airship performance or capability targets, and the missions these activities were addressing. The resulting report details the principal technical features of these airships, the proposed value/advantages of the features, notional concepts of operation, and challenges associated with such vehicles. The study investigated the current status and near-term prospects of these airship development activities, whether they are active or, if curtailed, the circumstances and possible reasons for that conclusion, including technical, business, or other mitigating factors. This presentation provides highlights of the Airship Industry Study investigations, findings, and recommendations. UAS Carrier Concept: The advantages of utilizing an airship as an airborne carrier for support and deployment of Unmanned Aircraft Systems (UAS) are examined. Whether as a stand-alone platform or in concert with conventional aircraft, the airship UAS carrier provides a number of compelling benefits for both military and civilian missions. As a mobile base it can remain operational despite political fallout that may render ground or ocean based UAS sites unavailable. It offers the psychological impact of a power projection tool that has few geographical limits, and holds promise as a new method for cost-saving intelligence gathering. It is also adaptable for civilian variants for supporting: emergency response, security/surveillance, delivery of medical/food supplies, as well as commercial package delivery to metropolitan and remote communities.

Inelastic dark matter in light of DAMA/LIBRA

2009-02-15

Inelastic dark matter, in which weakly interacting massive particle (WIMP)-nucleus scatterings occur through a transition to an excited WIMP state {approx}100 keV above the ground state, provides a compelling explanation of the DAMA annual modulation signal. We demonstrate that the relative sensitivities of various dark matter direct detection experiments are modified such that the DAMA annual modulation signal can be reconciled with the absence of a reported signal at CDMS-Soudan, XENON10, ZEPLIN, CRESST, and KIMS for inelastic WIMPs with masses O(100 GeV). We review the status of these experiments, and make predictions for upcoming ones. In particular, we note thatmore » inelastic dark matter leads to highly suppressed signals at low energy, with most events typically occurring between 20 and 45 keV (unquenched) at xenon and iodine experiments, and generally no events at low ({approx}10 keV) energies. Suppressing the background in this high-energy region is essential to testing this scenario. The recent CRESST data suggest seven observed tungsten events, which is consistent with expectations from this model. If the tungsten signal persists at future CRESST runs, it would provide compelling evidence for inelastic dark matter, while its absence should exclude it.« less

The education sector offers compelling opportunities to address the shortcomings of traditional mental health delivery systems and to prevent and treat youth mental, emotional, and behavioral (MEB) problems. Recognizing that social and emotional wellness is intrinsically related to academic success, schools are moving to adopt multi-tier frameworks based on the public health model that provide a continuum of services to all children, including services to address both academic and MEB problems. In this article, we review the potential value of multi-tier frameworks in facilitating access to, and increasing the effectiveness of, mental health services in schools, and review the empirical support for school-based mental health interventions by tier. We go on to describe a community-academic partnership between the Seattle Public Schools and the University of Washington School Mental Health Assessment, Research, and Training (SMART) Center that exemplifies how multi-tier educational frameworks, research and evidence, and purposeful collaboration can combine to improve development and implementation of a range of school-based strategies focused on MEB needs of students. Finally, we present a set of 10 recommendations that may help guide other research and practice improvement efforts to address MEB problems in youth through effective school mental health programming.

Adaptive radiation resulting from differential selection acting on functional features is believed to be an important source of biodiversity. In this study, morphometric measures and mitochondrial DNA are used to test for adaptive radiation within four fish genera (Glossogobius, Oryzias, Dermogenys and Telmatherina) endemic to an ancient island lake (Lake Matano, Sulawesi, Indonesia), using the framework proposed by Schluter (The Ecology of Adaptive Radiation, Oxford University Press, 2000). We demonstrate common ancestry and rapid divergence in one genus (Telmatherina) based on 560 bp of 16S sequence data. We found higher levels of variation in feeding-related traits (N = 8) for Telmatherina relative to the other genera, while no differences were found for sexual display traits (N = 8) or neutral morphological traits (N = 8). Telmatherina also had the highest number of distinct colouration patterns among the four genera. These data, combined with the very low productivity of the lake, are indicative of selection driving adaptive radiation. The morphometric divergence in the Telmatherina likely results from selection acting on feeding traits in this low productivity lake, leading to trophic specialization among closely related morphotypes. These results provide indirect but compelling data supporting the adaptive radiation of Telmatherina in this system.

Nutritional habits, risk, and progression of Parkinson disease.

Parkinson disease (PD) is a multifactorial disease, where a genetic predisposition combines with putative environmental risk factors. Mounting evidence suggests that the initial PD pathological manifestations may be located in the gut to subsequently affect brain areas. Moreover, several lines of research demonstrated that there are bidirectional connections between the central nervous system and the gut, the "gut-brain axis" that influences both brain and gastrointestinal function. This opens a potential therapeutic window suggesting that specific dietary strategies may interact with the disease process and influence the risk of PD or modify its course. Dietary components can also theoretically modulate the chronic activation of the inflammatory response that is associated with aging, the strongest risk factor for PD, that has been suggested to hasten the underlying neurodegenerative process in PD. Here, we reviewed the evidence supporting an association between certain dietary compound and either the risk or progression of PD and have provided an overview of the possible pathomechanisms linking nutrition and neurodegeneration. The results of our review would not support a clear role for any dietary components in reducing the risk or progression of PD. However, the evidence favouring a connection between gut abnormalities, inflammation, and neurodegeneration in PD have become too compelling to be ignored, so that further research, also in the field of nutritional genomics, is highly warranted.

The word class effect in the picture–word interference paradigm

2010-01-01

The word class effect in the picture–word interference paradigm is a highly influential finding that has provided some of the most compelling support for word class constraints on lexical selection. However, methodological concerns called for a replication of the most convincing of those effects. Experiment 1 was a direct replication of Pechmann and Zerbst (2002; Experiment 4). Participants named pictures of objects in the context of noun and adverb distractors. Naming took place in bare noun and sentence frame contexts. A word class effect emerged in both bare noun and sentence frame naming conditions, suggesting a semantic origin of the effect. In Experiment 2, participants named objects in the context of noun and verb distractors whose word class relationship to the target and imageability were orthogonally manipulated. As before, naming took place in bare noun and sentence frame naming contexts. In both naming contexts, distractor imageability but not word class affected picture naming latencies. These findings confirm the sensitivity of the picture–word interference paradigm to distractor imageability and suggest the paradigm is not sensitive to distractor word class. The results undermine the use of the word class effect in the picture–word interference paradigm as supportive of word class constraints during lexical selection. PMID:19998070

Purpose: To examine the impact of cancer on work and education for AYA. Collect information about AYA's return to work/return to study. Methods: 18 AYA (10 female) aged 18 to 39 (m=27 years) at time of diagnosis completed a semi-structured interview. Qualitative content analysis was used to generate results. Results: 11 of 18 AYA had already returned to work/study. Flexible structures and emotional support of colleagues and managers were reported being helpful. 10 AYA planed or had already reduced job tasks, hours of work or further education. This was mostly compelled by physical disabilities due to cancer or treatment. Most AYA asked for more support within the social insurance system. Conclusions: Cancer often leads to changes in work or education. More social and vocational counseling to support AYA's rehabilitation process seems to be necessary. © Georg Thieme Verlag KG Stuttgart · New York.

Effects of workplace, family and cultural influences on low back pain: what opportunities exist to address social factors in general consultations?

PubMed

Shaw, William S; Campbell, Paul; Nelson, Candace C; Main, Chris J; Linton, Steven J

2013-10-01

Social factors are widely acknowledged in behavioural models of pain and pain management, but incorporating these factors into general medical consultations for low back pain (LBP) can be challenging. While there is no compelling evidence that social factors contribute to LBP onset, these factors have been shown to influence functional limitation and disability, especially the effects of organisational support in the workplace, spousal support, family conflict and social disadvantage. A number of barriers exist to address such social factors in routine medical encounters for LBP, but there is emerging evidence that improving social and organisational support may be an effective strategy to reduce the negative lifestyle consequences of LBP. For clinicians to address these factors in LBP treatment requires a clearer psychosocial framework in assessment and screening, more individualised problem-solving efforts, more patient-centred interventions involving family, peers and workplace supports and a less biomechanical and diagnostic approach.

Support Needs of Fathers of Children with ASD: Individual, Family, Community and Ideological Influences.

Shave, Kassi; Lashewicz, Bonnie

2016-11-01

Fathers are increasingly involved in caring for children, and involvement by fathers of children with ASD is distinctly impacted by added demands of their child's diagnosis. Yet supports for families of children with ASD are not tailored to needs of fathers. We use an ecological framework to examine how fathers' needs are influenced by contexts ranging from the immediacy of their child's behaviour to overarching expectations for good fathering. We thematically analyse data from semi-structured interviews with 28 fathers of children with ASD who shared parenting stories of navigating their immediate and broader environments. Fathers are responsive and reflective in their parenting and value recreationally based support activities that include their children. Fathers endorse father-to-father support and are interested in mentoring fathers newer to the experience of having a child with ASD. Fathers are resourceful parents who compel a critical re-examination towards advances in father-friendly practices. © 2015 John Wiley & Sons Ltd.

2013-05-10

A substantive literature has drawn a compelling case for the functional involvement of mesolimbic/prefrontal cortical neural reward systems in normative control of eating and in the etiology and persistence of severe eating disorders that affect diverse human populations. Presently, we provide a short review that develops an equally compelling case for the importance of dysregulated frontal cortical cognitive neural networks acting in concert with regional reward systems in the regulation of complex eating behaviors and in the presentation of complex pathophysiological symptoms associated with major eating disorders. Our goal is to highlight working models of major eating disorders that incorporate complementary approaches to elucidate functionally interactive neural circuits defined by their regulatory neurochemical phenotypes. Importantly, we also review evidence-based linkages between widely studied psychiatric and neurodegenerative syndromes (e.g., autism spectrum disorders and Parkinson's disease) and co-morbid eating disorders to elucidate basic mechanisms involving dopaminergic transmission and its regulation by endogenously expressed morphine in these same cortical regions.

Interesting Practitioners in Training in Empirically Supported Treatments: Research Reviews versus Case Studies

Stewart, Rebecca E.; Chambless, Dianne L.

2010-01-01

It has been repeatedly demonstrated that clinicians rely more on clinical judgment than on research findings. We hypothesized that psychologists in practice might be more open to adopting empirically supported treatments (ESTs) if outcome results were presented with a case study. Psychologists in private practice (N = 742) were randomly assigned to receive a research review of data from randomized controlled trials of cognitive-behavioral treatment (CBT) and medication for bulimia, a case study of CBT for a fictional patient with bulimia, or both. Results indicated that the inclusion of case examples renders ESTs more compelling and interests clinicians in gaining training. Despite these participants’ training in statistics, the inclusion of the statistical information had no influence on attitudes or training willingness beyond that of the anecdotal case information.

2016-11-01

Obesity rates have increased dramatically, especially among children and disadvantaged populations. Obesity is a complex issue, creating a compelling need for prevention efforts in communities to move from single isolated programs to comprehensive multisystem interventions. To address these issues, we have established a childhood Obesity Prevention Initiative (Initiative) for Wisconsin. This Initiative seeks to test community change frameworks that can support multisystem interventions and provide data for local action as a means for influencing policies, systems, and environments that support individuals’ healthy eating and physical activity. The Initiative is comprised of three components: (1) infrastructure to support a statewide obesity prevention and health promotion network with state- and local-level public messaging and dissemination of evidence-based solutions (healthTIDE); (2) piloting a local, multisetting community-led intervention study in 2 Wisconsin counties; and (3) developing a geocoded statewide childhood obesity and fitness surveillance system. This Initiative is using a new model that involves both coalition action and community organizing to align resources to achieve health improvement at local and state levels. We expect that it will help lead to the implementation of cohesive and sustainable policy, system, and environment health promotion and obesity prevention strategies in communities statewide, and it has the potential to help Wisconsin become a national model for multisetting community interventions to address obesity. Addressing individual-level health through population-level changes ultimately will result in reductions in the prevalence of childhood obesity, current and future health care costs, and chronic disease mortality.

Entorhinal volume, aerobic fitness, and recognition memory in healthy young adults: A voxel-based morphometry study.

PubMed

Whiteman, Andrew S; Young, Daniel E; Budson, Andrew E; Stern, Chantal E; Schon, Karin

2016-02-01

Converging evidence supports the hypothesis effects of aerobic exercise and environmental enrichment are beneficial for cognition, in particular for hippocampus-supported learning and memory. Recent work in humans suggests that exercise training induces changes in hippocampal volume, but it is not known if aerobic exercise and fitness also impact the entorhinal cortex. In animal models, aerobic exercise increases expression of growth factors, including brain derived neurotrophic factor (BDNF). This exercise-enhanced expression of growth hormones may boost synaptic plasticity, and neuronal survival and differentiation, potentially supporting function and structure in brain areas including but not limited to the hippocampus. Here, using voxel based morphometry and a standard graded treadmill test to determine cardio-respiratory fitness (Bruce protocol; ·VO2 max), we examined if entorhinal and hippocampal volumes were associated with cardio-respiratory fitness in healthy young adults (N=33). In addition, we examined if volumes were modulated by recognition memory performance and by serum BDNF, a putative marker of synaptic plasticity. Our results show a positive association between volume in right entorhinal cortex and cardio-respiratory fitness. In addition, average gray matter volume in the entorhinal cortex, bilaterally, was positively associated with memory performance. These data extend prior work on the cerebral effects of aerobic exercise and fitness to the entorhinal cortex in healthy young adults thus providing compelling evidence for a relationship between aerobic fitness and structure of the medial temporal lobe memory system.

Phylogenetic reconstruction using four low-copy nuclear loci strongly supports a polyphyletic origin of the genus Sorghum

PubMed Central

Hawkins, Jennifer S.; Ramachandran, Dhanushya; Henderson, Ashley; Freeman, Jasmine; Carlise, Michael; Harris, Alex; Willison-Headley, Zachary

2015-01-01

Background and Aims Sorghum is an essential grain crop whose evolutionary placement within the Andropogoneae has been the subject of scrutiny for decades. Early studies using cytogenetic and morphological data point to a poly- or paraphyletic origin of the genus; however, acceptance of poly- or paraphyly has been met with resistance. This study aimed to address the species relationships within Sorghum, in addition to the placement of Sorghum within the tribe, using a phylogenetic approach and employing broad taxon sampling. Methods From 16 diverse Sorghum species, eight low-copy nuclear loci were sequenced that are known to play a role in morphological diversity and have been previously used to study evolutionary relationships in grasses. Further, the data for four of these loci were combined with those from 57 members of the Andropogoneae in order to determine the placement of Sorghum within the tribe. Both maximum likelihood and Bayesian analyses were performed on multilocus concatenated data matrices. Key Results The Sorghum-specific topology provides strong support for two major lineages, in alignment with earlier studies employing chloroplast and internal transcribed spacer (ITS) markers. Clade I is composed of the Eu-, Chaeto- and Heterosorghum, while clade II contains the Stipo- and Parasorghum. When combined with data from the Andropogoneae, Clade II resolves as sister to a clade containing Miscanthus and Saccharum with high posterior probability and bootstrap support, and to the exclusion of Clade I. Conclusions The results provide compelling evidence for a two-lineage polyphyletic ancestry of Sorghum within the larger Andropogoneae, i.e. the derivation of the two major Sorghum clades from a unique common ancestor. Rejection of monophyly in previous molecular studies is probably due to limited taxon sampling outside of the genus. The clade consisting of Para- and Stiposorghum resolves as sister to Miscanthus and Saccharum with strong node support. PMID:26141132

Analysis of complete mitochondrial genomes from extinct and extant rhinoceroses reveals lack of phylogenetic resolution

2009-01-01

Background The scientific literature contains many examples where DNA sequence analyses have been used to provide definitive answers to phylogenetic problems that traditional (non-DNA based) approaches alone have failed to resolve. One notable example concerns the rhinoceroses, a group for which several contradictory phylogenies were proposed on the basis of morphology, then apparently resolved using mitochondrial DNA fragments. Results In this study we report the first complete mitochondrial genome sequences of the extinct ice-age woolly rhinoceros (Coelodonta antiquitatis), and the threatened Javan (Rhinoceros sondaicus), Sumatran (Dicerorhinus sumatrensis), and black (Diceros bicornis) rhinoceroses. In combination with the previously published mitochondrial genomes of the white (Ceratotherium simum) and Indian (Rhinoceros unicornis) rhinoceroses, this data set putatively enables reconstruction of the rhinoceros phylogeny. While the six species cluster into three strongly supported sister-pairings: (i) The black/white, (ii) the woolly/Sumatran, and (iii) the Javan/Indian, resolution of the higher-level relationships has no statistical support. The phylogenetic signal from individual genes is highly diffuse, with mixed topological support from different genes. Furthermore, the choice of outgroup (horse vs tapir) has considerable effect on reconstruction of the phylogeny. The lack of resolution is suggestive of a hard polytomy at the base of crown-group Rhinocerotidae, and this is supported by an investigation of the relative branch lengths. Conclusion Satisfactory resolution of the rhinoceros phylogeny may not be achievable without additional analyses of substantial amounts of nuclear DNA. This study provides a compelling demonstration that, in spite of substantial sequence length, there are significant limitations with single-locus phylogenetics. We expect further examples of this to appear as next-generation, large-scale sequencing of complete mitochondrial genomes becomes commonplace in evolutionary studies.

Cell-Free Fetal DNA, Telomeres, and the Spontaneous Onset of Parturition.

PubMed

Phillippe, Mark

2015-10-01

Multiple previous reports have provided compelling support for the premise that spontaneous parturition is mediated by activation of inflammation-related signaling pathways leading to increased secretion of cytokines and chemokines, the influx of neutrophils and macrophages into the pregnant uterus, increased production of uterine activation proteins (eg, connexin-43, cyclo-oxygenase-2, oxytocin receptors, etc), activation of matrix metalloproteinases, and the release of uterotonins leading to cervical ripening, membrane rupture, and myometrial contractions. The missing link has been the fetal/placental signal that triggers these proinflammatory events in the absence of microbial invasion and intrauterine infection. This article reviews the biomedical literature regarding the increase in cell-free fetal DNA (cffDNA), which is released during apoptosis in the placenta and fetal membranes at term, the ability of apoptosis modified vertebrate DNA to stimulate toll-like receptor-9 (TLR9) leading to increased release of cytokines and chemokines, and the potential "fail-safe" role for the anti-inflammatory cytokine IL-10. This article also reviews the literature supporting the key role that telomere loss plays in regard to increasing the ability of vertebrate (including placental) DNA to stimulate TLR9, and in regard to signaling the onset of apoptosis in the placenta and fetal membranes, thereby providing a biologic clock that determines the length of gestation and the timing for the onset of parturition. In summary, this literature review provides a strong rationale for future research to test the hypothesis that telomere loss and increased cffDNA levels trigger the proinflammatory events leading to the spontaneous onset of parturition in mammals: the "cffDNA/telomere hypothesis." © The Author(s) 2015.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common complications of obesity. Several studies have shown that genetic predisposition probably plays an important role in its pathogenesis. In fact, in the last few years a large number of genetic studies have provided compelling evidence that some gene variants, especially those in genes encoding proteins regulating lipid metabolism, are associated with intra-hepatic fat accumulation. Here we provide a comprehensive review of the gene variants that have affected the natural history of the disease. PMID:28629152

The rise of high-throughput sequencing techniques provides the unprecedented opportunity to analyse controversial phylogenetic relationships in great depth, but also introduces a risk of being misinterpreted by high node support values influenced by unevenly distributed missing data or unrealistic model assumptions. Here, we use three largely independent phylogenomic data sets to reconstruct the controversial phylogeny of true salamanders of the genus Salamandra, a group of amphibians providing an intriguing model to study the evolution of aposematism and viviparity. For all six species of the genus Salamandra, and two outgroup species from its sister genus Lyciasalamandra, we used RNA sequencing (RNAseq) and restriction site associated DNA sequencing (RADseq) to obtain data for: (1) 3070 nuclear protein-coding genes from RNAseq; (2) 7440 loci obtained by RADseq; and (3) full mitochondrial genomes. The RNAseq and RADseq data sets retrieved fully congruent topologies when each of them was analyzed in a concatenation approach, with high support for: (1) S. infraimmaculata being sister group to all other Salamandra species; (2) S. algira being sister to S. salamandra; (3) these two species being the sister group to a clade containing S. atra, S. corsica and S. lanzai; and (4) the alpine species S. atra and S. lanzai being sister taxa. The phylogeny inferred from the mitochondrial genome sequences differed from these results, most notably by strongly supporting a clade containing S. atra and S. corsica as sister taxa. A different placement of S. corsica was also retrieved when analysing the RNAseq and RADseq data under species tree approaches. Closer examination of gene trees derived from RNAseq revealed that only a low number of them supported each of the alternative placements of S. atra. Furthermore, gene jackknife support for the S. atra - S. lanzai node stabilized only with very large concatenated data sets. The phylogeny of true salamanders thus provides a compelling example of how classical node support metrics such as bootstrap and Bayesian posterior probability can provide high confidence values in a phylogenomic topology even if the phylogenetic signal for some nodes is spurious, highlighting the importance of complementary approaches such as gene jackknifing. Yet, the general congruence among the topologies recovered from the RNAseq and RADseq data sets increases our confidence in the results, and validates the use of phylotranscriptomic approaches for reconstructing shallow relationships among closely related taxa. We hypothesize that the evolution of Salamandra has been characterized by episodes of introgressive hybridization, which would explain the difficulties of fully reconstructing their evolutionary relationships.

Changing What You See by Changing What You Know: The Role of Attention

PubMed Central

Lupyan, Gary

2017-01-01

Attending is a cognitive process that incorporates a person’s knowledge, goals, and expectations. What we perceive when we attend to one thing is different from what we perceive when we attend to something else. Yet, it is often argued that attentional effects do not count as evidence that perception is influenced by cognition. I investigate two arguments often given to justify excluding attention. The first is arguing that attention is a post-perceptual process reflecting selection between fully constructed perceptual representations. The second is arguing that attention as a pre-perceptual process that simply changes the input to encapsulated perceptual systems. Both of these arguments are highly problematic. Although some attentional effects can indeed be construed as post-perceptual, others operate by changing perceptual content across the entire visual hierarchy. Although there is a natural analogy between spatial attention and a change of input, the analogy falls apart when we consider other forms of attention. After dispelling these arguments, I make a case for thinking of attention not as a confound, but as one of the mechanisms by which cognitive states affect perception by going through cases in which the same or similar visual inputs are perceived differently depending on the observer’s cognitive state, and instances where cuing an observer using language affects what one sees. Lastly, I provide two compelling counter-examples to the critique that although cognitive influences on perception can be demonstrated in the laboratory, it is impossible to really experience them for oneself in a phenomenologically compelling way. Taken together, the current evidence strongly supports the thesis that what we know routinely influences what we see, that the same sensory input can be perceived differently depending on the current cognitive state of the viewer, and that phenomenologically salient demonstrations are possible if certain conditions are met.

Developing Aesthetically Compelling Visualizations for Documenting and Communicating Alaskan Glacier and Landscape Change

NASA Astrophysics Data System (ADS)

Molnia, B. F.

2016-12-01

For 50 years I have investigated glacier dynamics and attempted to convey this information to others. Since 2000, my focus has been on capturing and documenting decadal and century-scale Alaskan glacier and landscape change using precision repeat photography and on broadly communicate these results through simple, aesthetically compelling, unambiguous visualizations. As a young geologist, I spent the summer of 1968 on the Juneau Icefield, photographing its surface features and margins. Since then, I have taken 150,000 photographs of Alaskan glaciers and collected 5,000 historical Alaskan photographs taken by other, the earliest dating back to 1883. This database and my passion for photographing glaciers became the basis for an on-going investigation aimed at visually documenting glacier and landscapes change at more than 200 previously photographed Alaskan locations in Glacier Bay and Kenai Fjords National Parks, Prince William Sound, and the Coast Mountains. Repeat photography is a technique in which a historical and a modern photograph, both having similar fields of view, are compared and contrasted to quantitatively and qualitatively determine their similarities and differences. In precision repeat photography, both photographs have the same field of view, ideally being photographed from the identical location. Since 2000, I have conducted nearly 20 field campaigns to systematically revisit and re-photograph more than 225 fields of view previously captured in the historical photographs. As aesthetics are important in successfully communicating what has changed, substantial time and effort is invested in capturing new, comparable, generally cloud free photographs at each revisited site. The resulting modern images are then paired with similar field-of-view historical images to produce compelling, aesthetic photo pairs which depict long-term glacier, landscape, and ecosystem changes. As a few sites have multiple historical images, photo triplets or quadruplets are sometimes possible. Several approaches have been tried to produce aesthetic compelling visualization. These have included sliders, dissolves, adjacent pairs, a website, and DVDs. Providing high resolution pairs to users and letting them adapt the images to their individual needs has also been very successful.

In contrast, the magnetic field data obtained by the Galileo spacecraft and presented in the report by Kivelson et al., provide persuasive evidence for a conducting layer--most likely a global water ocean--near Europa's surface.

An integrated approach to stakeholder engagement.

Carr, Dafna; Howells, Arlene; Chang, Melissa; Hirji, Nadir; English, Ann

2009-01-01

The Wait Time Information System (WTIS) project was a complex change-management initiative. For the first time in Ontario, wait time data would be captured directly from clinician offices and publicly reported in an effort to improve access to care. The change meant using new technology, new business processes and, most importantly, a new dimension of accountability for making improvements within the health system. Success required engaging thousands of individuals at all levels of healthcare, many of whom were skeptical and resistant to the upcoming change, and subsequently gaining their support and motivating them to use the WTIS and its data. To achieve the level of stakeholder engagement that would be required to deploy and sustain the WTIS, the project team needed to address both the business reasons for change, and the emotional reactions to it. The team applied a three-pronged approach encompassing strong communications, compelling adoption efforts and hands-on training. Communication focused on awareness and education, ensuring that information was coordinated, consistent and transparent. Adoption efforts involved helping hospitals and users understand and prepare for the impact of change. Training provided hands-on practice to get people comfortable with using the system. This article explores how information management/information technology (IM/IT) projects can integrate communications, adoption and training to drive stakeholder engagement. It also provides insight around how, when used effectively, these functions can maximize limited resources and provide valuable benefits.

Legally protecting and compelling veterinarians in issues of animal abuse and domestic violence.

PubMed

Robertson, I A

2010-06-01

The majority of veterinarians recognise their important role and responsibility to society and animal welfare in the detection and reporting of suspected abuse of animals and humans. In spite of the existing moral, ethical, and legal duties applied to veterinarians, they face substantial barriers that prohibit them from fulfilling their professional role in handling cases of suspected abuse. With increasing public and legal attention on issues of animal welfare, the non-fulfillment of these duties places the profession and its members at considerable risk of public criticism and adverse legal accountability. The issue is raised here that the veterinary profession in New Zealand needs to provide a clear policy statement and take pro-active measures that provide practical enforceable solutions to these existing barriers and legal risks. Such an initiative will assist in ensuring that all registered members consistently fulfil their obligations, and are legally protected while doing so. Veterinary counterparts overseas already provide a legislative immunity for their veterinarians who report suspected abuse as part of a mandated duty to report. Implementation of such a duty has significant benefits for all veterinarians, including the requirement for education and effective support systems. In the absence of such a mandatory duty, intermediary measures can be introduced, demonstrating social responsibility and commitment by the profession to their existing duty of care.

Measurement invariance of neuropsychological tests in diverse older persons.

2011-03-01

Comparability of meaning of neuropsychological test results across ethnic, linguistic, and cultural groups is important for clinicians challenged with assessing increasing numbers of older ethnic minorities. We examined the dimensional structure of a neuropsychological test battery in linguistically and demographically diverse older adults. The Spanish and English Neuropsychological Assessment Scales (SENAS), developed to provide psychometrically sound measures of cognition for multiethnic and multilingual applications, was administered to a community dwelling sample of 760 Whites, 443 African Americans, 451 English-speaking Hispanics, and 882 Spanish-speaking Hispanics. Cognitive function spanned a broad range from normal to mildly impaired to demented. Multiple group confirmatory factor analysis was used to examine equivalence of the dimensional structure for the SENAS across the groups defined by language and ethnicity. Covariance among 16 SENAS tests was best explained by five cognitive dimensions corresponding to episodic memory, semantic memory/language, spatial ability, attention/working memory, and verbal fluency. Multiple Group confirmatory factor analysis supported a common dimensional structure in the diverse groups. Measures of episodic memory showed the most compelling evidence of measurement equivalence across groups. Measurement equivalence was observed for most but not all measures of semantic memory/language and spatial ability. Measures of attention/working memory defined a common dimension in the different groups, but results suggest that scores are not strictly comparable across groups. These results support the applicability of the SENAS for use with multiethnic and bilingual older adults, and more broadly, provide evidence of similar dimensions of cognition in the groups represented in the study.

Lactate Racemase Nickel-Pincer Cofactor Operates by a Proton-Coupled Hydride Transfer Mechanism.

Lactate racemase (LarA) of Lactobacillus plantarum contains a novel organometallic cofactor with nickel coordinated to a covalently tethered pincer ligand, pyridinium-3-thioamide-5-thiocarboxylic acid mononucleotide, but its function in the enzyme mechanism has not been elucidated. This study presents direct evidence that the nickel-pincer cofactor facilitates a proton-coupled hydride transfer (PCHT) mechanism during LarA-catalyzed lactate racemization. No signal was detected by electron paramagnetic resonance spectroscopy for LarA in the absence or presence of substrate, consistent with a +2 metal oxidation state and inconsistent with a previously proposed proton-coupled electron transfer mechanism. Pyruvate, the predicted intermediate for a PCHT mechanism, was observed in quenched solutions of LarA. A normal substrate kinetic isotope effect ( k H / k D of 3.11 ± 0.17) was established using 2-α- 2 H-lactate, further supporting a PCHT mechanism. UV-visible spectroscopy revealed a lactate-induced perturbation of the cofactor spectrum, notably increasing the absorbance at 340 nm, and demonstrated an interaction of the cofactor with the inhibitor sulfite. A crystal structure of LarA provided greater resolution (2.4 Å) than previously reported and revealed sulfite binding to the pyridinium C4 atom of the reduced pincer cofactor, mimicking hydride reduction during a PCHT catalytic cycle. Finally, computational modeling supports hydride transfer to the cofactor at the C4 position or to the nickel atom, but with formation of a nickel-hydride species requiring dissociation of the His200 metal ligand. In aggregate, these studies provide compelling evidence that the nickel-pincer cofactor acts by a PCHT mechanism.

Trace elements as paradigms of developmental neurotoxicants: lead, methylmercury and arsenic

PubMed Central

Grandjean, Philippe; Herz, Katherine T.

2014-01-01

Trace elements have contributed unique insights into developmental neurotoxicity and serve as paradigms for such adverse effects. Many trace elements are retained in the body for long periods and can be easily measured to assess exposure by inexpensive analytical methods that became available several decades ago so that past and cumulated exposures could be easily characterized through analysis of biological samples, e.g. blood and urine. The first compelling evidence resulted from unfortunate poisoning events that allowed scrutiny of long-term outcomes of acute exposures that occurred during early development. Pursuant to this documentation, prospective studies of children's cohorts that applied sensitive neurobehavioral methods supported the notion that the brain is uniquely vulnerable to toxic damage during early development. Lead, methylmercury, and arsenic thereby serve as paradigm neurotoxicants that provide a reference for other substances that may have similar adverse effects. Less evidence is available on manganese, fluoride, and cadmium, but experience from the former trace elements suggest that, with time, adverse effects are likely to be documented at exposures previously thought to be low and safe.

In the scientific description of unconventional transport properties of oxides (spin-dependent transport, superconductivity etc.), the spin-state degree of freedom plays a fundamental role. Because of this, temperature- or magnetic field-induced spin-state transitions are in the focus of solid-state physics. Cobaltites, e.g. LaCoO3, are prominent examples showing these spin transitions. However, the microscopic nature of the spontaneous spin crossover in LaCoO3 is still controversial. Here we report magnetostriction measurements on LaCoO3 in magnetic fields up to 70 T to study the sharp, field-induced transition at Hc ≈ 60 T. Measurements of both longitudinal and transversal magnetostriction allow us to separate magnetovolume and magnetodistortive changes. We find a large increase in volume, but only a very small increase in tetragonal distortion at Hc. The results, supported by electronic energy calculations by the configuration interaction cluster method, provide compelling evidence that above Hc LaCoO3 adopts a correlated low spin/high spin state.

2011-11-01

Chronic lower quadrant injuries constitute a significant percentage of the musculoskeletal cases seen by clinicians. While impairments may vary, pain is often the factor that compels the patient to seek medical attention. Traumatic injury from sport is one cause of progressive chronic joint pain, particularly in the lower quarter. Recent studies have demonstrated the presence of peripheral and central sensitization mechanisms in different lower quadrant pain syndromes, such as lumbar spine related leg pain, osteoarthritis of the knee, and following acute injuries such as lateral ankle sprain and anterior cruciate ligament rupture. Proper management of lower quarter conditions should include assessment of balance and gait as increasing pain and chronicity may lead to altered gait patterns and falls. In addition, quantitative sensory testing may provide insight into pain mechanisms which affect management and prognosis of musculoskeletal conditions. Studies have demonstrated analgesic effects and modulation of spinal excitability with use of manual therapy techniques, with clinical outcomes of improved gait and functional ability. This paper will discuss the evidence which supports the use of manual therapy for lower quarter musculoskeletal dysfunction.

Using Kepler K2 to Measure the Binary Fraction of PN Central Stars

2018-01-01

During the initial Kepler mission, 5 Planetary Nebula (PN) central stars were observed. The light curves for 4 of these central stars indicated a history of close binary interactions. That large fraction was suggestive that the actual fraction of PN harboring close binaries is much larger than the known lower limit of 20%, but that sample is far too small to be compelling. We have since acquired Kepler K2 data for Campaigns 0, 2, 7, and 11, hosting PN samples of 3, 4, 8, and 185 targets, respectively. We will provide an update on the number of binary candidates found in each field, and in particular, the Galactic Bulge field of Campaign 11. We also will discuss the challenges of working with Kepler observations in the crowded Campaign 11 field and the impact of those challenges on our ability to estimate the fraction of PN central stars that are binaries. This study was supported in part by NASA grants NNX17AE64G and NNX17AF80G.

A number of recent studies have provided compelling demonstrations that both mice and rats can be trained to perform a variety of behavioral tasks while restrained by mechanical elements mounted to the skull. The independent development of this technique by a number of laboratories has led to diverse solutions. We found that these solutions often used expensive materials and impeded future development and modification in the absence of engineering support. In order to address these issues, here we report on the development of a flexible single hardware design for electrophysiology and imaging both in brain tissue in vitro. Our hardware facilitates the rapid conversion of a single preparation between physiology and imaging system and the conversion of a given system between preparations. In addition, our use of rapid prototyping machines (“3D printers”) allows for the deployment of new designs within a day. Here, we present specifications for design and manufacturing as well as some data from our lab demonstrating the suitability of the design for physiology in behaving animals and imaging in vitro and in vivo.

Episodic memory, semantic memory, and amnesia.

PubMed

Squire, L R; Zola, S M

1998-01-01

Episodic memory and semantic memory are two types of declarative memory. There have been two principal views about how this distinction might be reflected in the organization of memory functions in the brain. One view, that episodic memory and semantic memory are both dependent on the integrity of medial temporal lobe and midline diencephalic structures, predicts that amnesic patients with medial temporal lobe/diencephalic damage should be proportionately impaired in both episodic and semantic memory. An alternative view is that the capacity for semantic memory is spared, or partially spared, in amnesia relative to episodic memory ability. This article reviews two kinds of relevant data: 1) case studies where amnesia has occurred early in childhood, before much of an individual's semantic knowledge has been acquired, and 2) experimental studies with amnesic patients of fact and event learning, remembering and knowing, and remote memory. The data provide no compelling support for the view that episodic and semantic memory are affected differently in medial temporal lobe/diencephalic amnesia. However, episodic and semantic memory may be dissociable in those amnesic patients who additionally have severe frontal lobe damage.

Fostering institutional practices in support of public engagement by scientists

Cobb, K. M.

2016-12-01

Scientists are increasingly called on to communicate the findings of their research outside the scientific sphere, to members of the public, media, and/or policymakers eager for information about topics at the intersections of science and society. While all scientists share a desire for a more informed public, and for the development of evidence-based public policy, there are profound hurdles that prevent most scientists from meaningfully engaging the public. Here, I identify and discuss both internal (i.e. finite time, discomfort in public speaking and interview settings, etc) and external (metrics for promotion and tenure, scholarly reputation, etc) obstacles for public engagement. At the same time, I also discuss how recent trends in scientific practice provide clear, concrete, and compelling rewards for public engagement. Specifically, institutions of higher education have a vested interest in fostering and rewarding greater public engagement by scientists across all academic ranks. I review a variety of innovative mechanisms, both informal and formal, that institutions are employing to achieve this goal, and assess their potential impact on the engagement levels of scientists.

DISCOVERY OF FOG AT THE SOUTH POLE OF TITAN

Brown, M. E.; Smith, A. L.; Chen, C.

2009-11-20

While Saturn's moon Titan appears to support an active methane hydrological cycle, no direct evidence for surface-atmosphere exchange has yet appeared. The indirect evidence, while compelling, could be misleading. It is possible, for example, that the identified lake features could be filled with ethane, an involatile long-term residue of atmospheric photolysis; the apparent stream and channel features could be ancient remnants of a previous climate; and the tropospheric methane clouds, while frequent, could cause no rain to reach the surface. We report here the detection of fog at the south pole of Titan during late summer using observations from themore » VIMS instrument on board the Cassini spacecraft. While terrestrial fog can form from a variety of causes, most of these processes are inoperable on Titan. Fog on Titan can only be caused by evaporation of nearly pure liquid methane; the detection of fog provides the first direct link between surface and atmospheric methane. Based on the detections presented here, liquid methane appears widespread at the south pole of Titan in late southern summer, and the hydrological cycle on Titan is currently active.« less

Sex hormone-binding globulin (SHBG) is the high-affinity binding protein for androgens and estrogens. According to the free hormone hypothesis, SHBG modulates the bioactivity of sex steroids by limiting their diffusion into target tissues. Still, the in vivo physiological role of circulating SHBG remains unclear, especially since mice and rats lack circulating SHBG post-natally. To test the free hormone hypothesis in vivo, we examined total and free sex steroid concentrations and bioactivity on target organs in mice expressing a human SHBG transgene. SHBG increased total androgen and estrogen concentrations via hypothalamic-pituitary feedback regulation and prolonged ligand half-life. Despite markedly raised total sex steroid concentrations, free testosterone was unaffected while sex steroid bioactivity on male and female reproductive organs was attenuated. This occurred via a ligand-dependent, genotype-independent mechanism according to in vitro seminal vesicle organ cultures. These results provide compelling support for the determination of free or bioavailable sex steroid concentrations in medicine, and clarify important comparative differences between translational mouse models and human endocrinology.

Accumulating evidence from brain structural imaging studies has supported that chronic pain could induce changes in brain gray matter volume. However, few studies have focused on the gray matter alterations of Trigeminal neuralgia (TN). In this study, twenty-eight TN patients (thirteen females; mean age, 45.86 years ±11.17) and 28 healthy controls (HC; thirteen females; mean age, 44.89 years ±7.67) were included. Using voxel-based morphometry (VBM), we detected abnormalities in gray matter volume in the TN patients. Based on a voxel-wise analysis, the TN group showed significantly decreased gray matter volume in the bilateral superior/middle temporal gyrus (STG/MTG), bilateral parahippocampus, left anterior cingulate cortex (ACC), caudate nucleus, right fusiform gyrus, and right cerebellum compared with the HC. In addition, we found that the gray matter volume in the bilateral STG/MTG was negatively correlated with the duration of TN. These results provide compelling evidence for gray matter abnormalities in TN and suggest that the duration of TN may be a critical factor associated with brain alterations.

Psychological assessment and intervention are extending from the clinic into daily life. Multiple forces are at play: Advances in mobile technology, constrained clinical care, and consumer demand for contextualized, nonstigmatizing, and low-cost alternatives are beginning to change the face of psychological assessment and interventions. Mobile, social, and wearable technologies are now enabling individuals to measure themselves and to integrate myriad forms of help and entertainment. The massive data sets generated by self-tracking of mood and passive sensing of voice, activity, and physiology may eventually reorganize taxonomies of mental health concerns. Compelling mobile therapies will also emerge, involving contextually appropriate, entertaining, and dynamic feedback to provide help in the context of daily life. The efficacy of such applications will be tested through citizen science as well as clinical trials. This article reviews technical advances that can be applied to enhance assessment and intervention and dramatically increase access to psychotherapy. It is recommended that, in addition to exploring clinically oriented products, practitioners should support patients' use of direct-to-consumer applications in ways that align with therapeutic objectives.

Cross-correlation between the 170 GHz survey map and the COBE differential microwave radiometer first-year maps

This letter describes results of a cross-correlation between the 170 GHz partial-sky survey, made with a 3.8 deg beam balloon-borne instrument, and the COBE DMR 'Fit Technique' reduced galaxy all-sky map with a beam of 7 deg. The strong correlation between the data sets implies that the observed structure is consistent with thermal variations in a 2.7 K emitter. A chi-square analysis applied to the correlation function rules out the assumption that there is no structure in either of the two maps. A second test shows that if the DMR map has structure but the 170 GHz map does not, the probability of obtaining the observed correlation is small. Further analyses support the assumption that both maps have structure and that the 170 GHz-DMR cross-correlation is consistent with the analogous DMR correlation function. Maps containing various combinations of noise and Harrison-Zel'dovich power spectra are simulated and correlated to reinforce the result. The correlation provides compelling evidence that both instruments have observed fluctuations consistent with anisotropies in the cosmic microwave background.

Producing "value-added students" involves proactively addressing how successfully students develop their skills, knowledge, and personal, social, and ethical growth due to their association with a program. NASA programs for higher education can certainly be responsive in aiding the academic community strive for quality in terms of "valueadded" students. By identifying essential characteristics of exemplary assessment practices, the standards developed by accrediting agencies serve as guides for developing quality practices and policies. Such a process is an effective tool for communicating the expectations of the educational components of a program to all concerned with the program and its expected results. When standards are connected to student performance, they provide a very compelling argument for refocusing the definition of quality in higher education. By linking standards and performance, student learning and development becomes the starting point for examining program quality. If the multiple stakeholders - faculty, peers, the professional community, addressed assessment issues, then accreditation can be a link among various constituencies, the parties can better understand the needs of each other and develop the necessary trust needed for understanding and support.

Ted Irving's legacy: recent developments on his pioneering work in paleomagnetism

Edward (Ted) Irving (1927-2014) was one of the principal developers of paleomagnetism and an early champion of continental drift. Through careful multidisciplinary research and with great insight, he pioneered many aspects of paleomagnetism which continue to be actively researched. Irving was convinced of the reality of continental drift by 1954 and provided compelling arguments for its support in his classic 1964 textbook, but thought it would take the rest of his career to convince the rest of the scientific community. With the acceptance of plate tectonics in the late 1960s, he then applied his paleomagnetic tools to study young rocks (mid-ocean ridges), old rocks (the Laurentian shield), and mobile belts (the Appalachians and the Cordillera). In this poster we highlight recent work on several of his methods, results and ideas. Topics will include spherical statistics and paleosecular variation, the geomagnetic polarity time scale and the Kiaman superchron, paleoclimatic tests of paleogeography, compilation of paleomagnetic poles and the definition of apparent polar wander paths, and the paleogeography of cratons (e.g., Pangea) and mobile belts (e.g., Baja BC).

The United States are amid an opioid overdose epidemic; we are challenged to provide non-addicting/non-pharmacological alternatives to assist in pain attenuation. There are proven strategies available to manage chronic pain effectively without opioids. Utilization review providers for insurance companies often ignore medicine based scientific peer-reviewed studies that warn against the chronic use of opioid medications, as well as the lack of evidence to support long-term use of opioids for pain. This paradigm must change if we are to indeed change the drug-embracing culture in American chronic pain management. A barrier to treatment is pushback on the part of insurance companies especially as it relates to fighting against pain relief alternatives compared to classical analgesic agents. Pain specialists in the U.S., are compelled to find alternative solutions to help pain victims without promoting unwanted tolerance to analgesics and subsequent biological induction of the "addictive brain." It is noteworthy that reward center of the brain plays a crucial role in the modulation of nociception, and that adaptations in dopaminergic circuitry may affect several sensory and affective components of chronic pain syndromes. Possibly knowing a patient's genetic addiction risk score (GARS™) could eliminate guessing as it relates to becoming addicted.

Forward Contamination of the Moon and Mars: Implications for Future Life Detection Missions

2004-01-01

NASA and ESA have outlined new visions for solar system exploration that will include a series of lunar robotic missions to prepare for, and support a human return to the Moon, and future human exploration of Mars and other destinations. One of the guiding principles for exploration is to pursue compelling scientific questions about the origin and evolution of life. The search for life on objects such as Mars will require that all spacecraft and instrumentation be sufficiently cleaned and sterilized prior to launch to ensure that the scientific integrity of extraterrestrial samples is not jeopardized by terrestrial organic contamination. Under COSPAR's current planetary protection policy for the Moon, no sterilization procedures are required for outbound lunar spacecraft. Nonetheless, future in situ investigations of a variety of locations on the Moon by highly sensitive instruments designed to search for biologically derived organic compounds would help assess the contamination of the Moon by lunar spacecraft. These studies could also provide valuable "ground truth" data for Mars sample return missions and help define planetary protection requirements for future Mars bound spacecraft carrying life detection experiments. In addition, studies of the impact of terrestrial contamination of the lunar surface by the Apollo astronauts could provide valuable data to help refine future Mars surface exploration plans for a human mission to Mars.

Which instructor qualities do students consider most important? The answer likely depends on the student. This study attempted to trace beliefs about the most essential instructor qualities to students' academic achievement goals. The present study tested the hypothesis that students pursuing mastery goals favour instructors who stimulate and challenge them intellectually, whereas those pursuing performance goals favour instructors who present material clearly and provide clear cues about how to succeed. Participants were 157 students at a 4-year public university. Participants designed the ideal professor through a hypothetical combination of nine widely valued instructor qualities, such as enthusiasm, presentation clarity, and an interactive teaching style. The more they acquired of any one instructor quality, the less they could acquire of the others, thus compelling students to distinguish necessary qualities from desirable luxury qualities. Students' achievement goals corresponded to their views about the most essential instructor qualities. Mastery goals predicted greater demand for professors who intellectually challenge students and possess topic expertise, whereas performance goals predicted high demand for professors who present material clearly and provide cues about how to succeed in the course. The findings support emerging theorizing about how mastery and performance goals nudge students to pursue different learning agendas, with distinct consequences to their learning experience. ©2011 The British Psychological Society.

Multidisciplinary life cycle metrics and tools for green buildings.

PubMed

Helgeson, Jennifer F; Lippiatt, Barbara C

2009-07-01

Building sector stakeholders need compelling metrics, tools, data, and case studies to support major investments in sustainable technologies. Proponents of green building widely claim that buildings integrating sustainable technologies are cost effective, but often these claims are based on incomplete, anecdotal evidence that is difficult to reproduce and defend. The claims suffer from 2 main weaknesses: 1) buildings on which claims are based are not necessarily "green" in a science-based, life cycle assessment (LCA) sense and 2) measures of cost effectiveness often are not based on standard methods for measuring economic worth. Yet, the building industry demands compelling metrics to justify sustainable building designs. The problem is hard to solve because, until now, neither methods nor robust data supporting defensible business cases were available. The US National Institute of Standards and Technology (NIST) Building and Fire Research Laboratory is beginning to address these needs by developing metrics and tools for assessing the life cycle economic and environmental performance of buildings. Economic performance is measured with the use of standard life cycle costing methods. Environmental performance is measured by LCA methods that assess the "carbon footprint" of buildings, as well as 11 other sustainability metrics, including fossil fuel depletion, smog formation, water use, habitat alteration, indoor air quality, and effects on human health. Carbon efficiency ratios and other eco-efficiency metrics are established to yield science-based measures of the relative worth, or "business cases," for green buildings. Here, the approach is illustrated through a realistic building case study focused on different heating, ventilation, air conditioning technology energy efficiency. Additionally, the evolution of the Building for Environmental and Economic Sustainability multidisciplinary team and future plans in this area are described.

Background The availability of clinical information and a pertinent clinical question can improve the diagnostic accuracy of the imaging process. Purpose To examine if an electronic request form forcing referring clinicians to provide separate input of both clinical information and a clinical question can improve the quality of the request. Material and Methods A total of 607 request forms in the clinical worklists for a computed tomography (CT) scan of the thorax, the abdomen or their combination, were examined. Using software of our own making, we examined the presence of clinical information and a clinical question before and after the introduction of a new, more compelling order method. We scored and compared the quality of the clinical information and the clinical question between the two systems and we examined the effect on productivity. Results Both clinical information and a clinical question were present in 76.7% of cases under the old system and in 95.3% under the new system ( P < 0.001). Individual characteristics of the clinical information and the clinical question however, with the exception of incompleteness, showed little improvement under the new system. There was also no significant difference between the two systems in the number of requests requiring further search. Conclusion The introduction of electronic radiology request forms compelling referring clinicians to provide separate input of clinical information and a clinical question provides only limited benefit to the quality of the request. Raising awareness among clinicians of the importance of a well-written request remains essential.

Rates and predictors of seizure freedom in resective epilepsy surgery: an update

PubMed Central

Englot, Dario J.; Chang, Edward F.

2017-01-01

Epilepsy is a debilitating neurological disorder affecting approximately 1 % of the world’s population. Drug-resistant focal epilepsies are potentially surgically remediable. Although epilepsy surgery is dramatically underutilized among medically refractory patients, there is an expanding collection of evidence supporting its efficacy which may soon compel a paradigm shift. Of note is that a recent randomized controlled trial demonstrated that early resection leads to considerably better seizure outcomes than continued medical therapy in patients with pharmacoresistant temporal lobe epilepsy. In the present review, we provide a timely update of seizure freedom rates and predictors in resective epilepsy surgery, organized by the distinct pathological entities most commonly observed. Class I evidence, meta-analyses, and individual observational case series are considered, including the experiences of both our institution and others. Overall, resective epilepsy surgery leads to seizure freedom in approximately two thirds of patients with intractable temporal lobe epilepsy and about one half of individuals with focal neocortical epilepsy, although only the former observation is supported by class I evidence. Two common modifiable predictors of postoperative seizure freedom are early operative intervention and, in the case of a discrete lesion, gross total resection. Evidence-based practice guidelines recommend that epilepsy patients who continue to have seizures after trialing two or more medication regimens should be referred to a comprehensive epilepsy center for multidisciplinary evaluation, including surgical consideration.

Extracellular Vesicles from Bone Marrow‐Derived Mesenchymal Stem Cells Improve Survival from Lethal Hepatic Failure in Mice

2017-01-01

Abstract Stem cell‐based therapies have potential for treatment of liver injury by contributing to regenerative responses, through functional tissue replacement or paracrine effects. The release of extracellular vesicles (EV) from cells has been implicated in intercellular communication, and may contribute to beneficial paracrine effects of stem cell‐based therapies. Therapeutic effects of bone‐marrow derived mesenchymal stem cells (MSC) and vesicles released by these cells were examined in a lethal murine model of hepatic failure induced by d‐galactosamine/tumor necrosis factor‐α (TNF‐α). Systemically administered EV derived from MSC accumulated within the injured liver following systemic administration, reduced hepatic injury, and modulated cytokine expression. Moreover, survival was dramatically increased by EV derived from either murine or human MSC. Similar results were observed with the use of cryopreserved mMSC‐EV after 3 months. Y‐RNA‐1 was identified as a highly enriched noncoding RNA within hMSC‐EV compared to cells of origin. Moreover, siRNA mediated knockdown of Y‐RNA‐1 reduced the protective effects of MSC‐EV on TNF‐α/ActD‐mediated hepatocyte apoptosis in vitro. These data support a critical role for MSC‐derived EV in mediating reparative responses following hepatic injury, and provide compelling evidence to support the therapeutic use of MSC‐derived EV in fulminant hepatic failure.

To examine the experiences of women who donated breast milk to a hospital-based milk bank regulated under the policies and procedures set forth by the Human Milk Banking Association of North America (HMBANA). Qualitative, phenomenological design. The Mothers' Milk Bank in a children's hospital in the Northeastern region of the United States. Twelve HMBANA-approved milk donors older than 21 years with infants hospitalized in the NICU. Edmund Husserl's design of interpretive phenomenology and Colaizzi's method of data analysis were used for this study. Participants were interviewed using a face-to-face, semistructured interview format. Four themes represented the experience of donating breast milk: Ripple of Hope and Help, Dynamic Interplay of Nurturance, Standing on the Shoulders of Others, and Sharing Their Stories. Donors felt proud and accomplished to provide hope for other infants and families. Nurses were crucial in facilitating and motivating donors and making donation achievable in a supportive environment. Donors felt compelled to share their experiences to teach and motivate others to donate. For our participants, donation of human milk was a positive, valuable, and nurturing experience. Donors reported feelings of increased self-esteem during donation that motivated them to "give back" and continue. The support of a well-trained nursing staff is essential for donors to meet their personal goals. Copyright © 2018 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

2017-09-01

Inflammation can promote the development of arthritis, obesity, cardiovascular, type II diabetes, pancreatitis, metabolic and neurodegenerative diseases, and certain types of cancer. Compounds isolated from plants have been practiced since ancient times for curing various ailments including inflammatory disorders and to support normal physiological functions. Curcumin (diferuloylmethane) is a yellow coloring agent, extracted from turmeric that has been used for the prevention and treatment of various inflammatory diseases. Numerous studies have shown that curcumin modulate multiple molecular targets and can be translated to the clinics for multiple therapeutic processes. There is compelling evidence that curcumin can block cell proliferation, invasion, and angiogenesis as well as reduced the prolonged survival of cancer cells. Curcumin mediates anti-inflammatory effect through downregulation of inflammatory cytokines, transcription factors, protein kinases, and enzymes that promote inflammation and development of chronic diseases. In addition, curcumin induces apoptosis through mitochondrial and receptor-mediated pathways by activating caspase cascades. Curcumin is a safe and nontoxic drug that has been reported to be well tolerated. Available clinical trials support the potential role of curcumin for treatment of various inflammatory disorders. However, curcumin's efficacy is hindered by poor absorption and low bioavailability, which limit its translation into clinics. This review outlines the potential pharmacological and clinical role of curcumin, which provide a gateway for the beneficial role of plant isolated compounds in treatment of various inflammatory diseases and cancer. © 2017 Institute of Food Technologists®.

A Review Of Innovative International Financing Mechanisms To Address Noncommunicable Diseases.

Meghani, Ankita; Basu, Sanjay

2015-09-01

Noncommunicable diseases have become prevalent in low- and middle-income countries. A key question that remains unresolved is how to support the development of systems to prevent and treat noncommunicable disease through international financing mechanisms. We conducted a review of articles and grey literature published from 2000 through 2014 on innovative financing models proposed or used for other disease control efforts. We found that the greatest available evidence supported pooled funding models, where funding from multiple groups is combined for a specific investment, with such models previously deployed in vaccine and infectious disease funding areas. Robust evidence also supported the viability of international transactions taxes or levies placed on specific transactions to fund investments in drug procurement and supply, and of the front-loading of development aid through bond sales, particularly to stabilize funding and subsidize drug procurement. Far less compelling evidence was available to support diaspora bonds or debt reduction programs as mechanisms to aid low- and middle-income countries' health systems in financing noncommunicable disease prevention and care services.

Moral injury: a mechanism for war-related psychological trauma in military family members.

PubMed

Nash, William P; Litz, Brett T

2013-12-01

Recent research has provided compelling evidence of mental health problems in military spouses and children, including post-traumatic stress disorder (PTSD), related to the war-zone deployments, combat exposures, and post-deployment mental health symptoms experienced by military service members in the family. One obstacle to further research and federal programs targeting the psychological health of military family members has been the lack of a clear, compelling, and testable model to explain how war-zone events can result in psychological trauma in military spouses and children. In this article, we propose a possible mechanism for deployment-related psychological trauma in military spouses and children based on the concept of moral injury, a model that has been developed to better understand how service members and veterans may develop PTSD and other serious mental and behavioral problems in the wake of war-zone events that inflict damage to moral belief systems rather by threatening personal life and safety. After describing means of adapting the moral injury model to family systems, we discuss the clinical implications of moral injury, and describe a model for its psychological treatment.

The effects of task difficulty and resource requirements on attention strategies

1991-01-01

The patterns of attention strategies for task difficulty/resource tasks for which experimental results are presented and analyzed support the hypothesis that subjects may adopt an alternating (rather than concurrent one) when compelled to do so by either the size or the complexity of a visual display. According to the multiple resource model, if subjects had been performing the two tasks concurrently, the cost of this strategy would have been shown by a decrement in the spatial format, rather than the verbal format, due to competition for the same resource. Subjects may apply different strategies as a function of task difficulty and/or resource demand.

Sirtuins in neurodegenerative diseases: an update on potential mechanisms

Min, Sang-Won; Sohn, Peter D.; Cho, Seo-Hyun; Swanson, Raymond A.; Gan, Li

2013-01-01

Silent information regulator 2 proteins (sirtuins or SIRTs) are a group of deacetylases (or deacylases) whose activities are dependent on and regulated by nicotinamide adenine dinucleotide (NAD+). Compelling evidence supports that sirtuins play major roles in many aspects of physiology, especially in pathways related to aging – the predominant and unifying risk factor for neurodegenerative diseases. In this review, we highlight the molecular mechanisms underlying the protective effects of sirtuins in neurodegenerative diseases, focusing on protein homeostasis, neural plasticity, mitochondrial function, and sustained chronic inflammation. We will also examine the potential and challenges of targeting sirtuin pathways to block these pathogenic pathways. PMID:24093018

Although acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are caused by different injuries and conditions, their similar clinical picture makes a compelling case for them to be studied as a single entity. An array of potential specific targets for pharmacologic intervention can be applied to ALI/ARDS as one disease. Although a working definition of ALI/ARDS that includes pulmonary and extrapulmonary causes can have benefit in standardizing supportive care, it can also complicate assessments of the efficacy of therapeutic interventions. In this article, definitions that have been recently used for ALI/ARDS in various clinical studies are discussed individually. Copyright © 2011 Elsevier Inc. All rights reserved.

Liberating Lévy walk research from the shackles of optimal foraging

NASA Astrophysics Data System (ADS)

Reynolds, Andy

2015-09-01

There is now compelling evidence that many organisms have movement patterns that can be described as Lévy walks, or Lévy flights. Lévy movement patterns have been identified in cells, microorganisms, molluscs, insects, reptiles, fish, birds and even human hunter-gatherers. Most research into Lévy walks as models of organism movement patterns has been shaped by the 'Lévy flight foraging hypothesis'. This states that, since Lévy walks can optimize search efficiencies, natural selection should lead to adaptations that select for Lévy walk foraging. However, a growing body of research on generative mechanisms suggests that Lévy walks can arise freely as by-products of otherwise innocuous behaviours; consequently their advantageous properties are purely coincidental. This suggests that the Lévy flight foraging hypothesis should be amended, or even replaced, by a simpler and more general hypothesis. This new hypothesis would state that 'Lévy walks emerge spontaneously and naturally from innate behaviours and innocuous responses to the environment but, if advantageous, then there could be selection against losing them'. The new hypothesis has the virtue of making fewer assumptions and being broader than the original hypothesis; it also encompasses the many examples of suboptimal Lévy patterns that challenge the prevailing paradigm. This does not detract from the Lévy flight foraging hypothesis, in fact, it adds to the theory by providing a stronger and more compelling case for the occurrence of Lévy walks. It dispenses with concerns about the theoretical arguments in support of the Lévy flight foraging hypothesis and so may lead to a wider acceptance of Lévy walks as models of movement pattern data. Furthermore, organisms can approximate Lévy walks by adapting intrinsic behaviour in simple ways; this occurs when Lévy movement patterns are advantageous, but come with an associated cost. These new developments represent a major change in perspective and provide the broadest picture yet of Lévy movement patterns. However, the process of understanding and identifying Lévy movement patterns still has a long way to go, and further reinterpretations and shifts in understanding will occur. In conclusion, Lévy walk research remains exciting precisely because so much remains to be understood, and because, even relatively small studies, are interesting discoveries in their own right.

Despite their physics instructors’ arguments to the contrary, introductory students can observe situations in which there seems to be compelling evidence for magnetic force doing work. The counterarguments are often highly technical and require physics knowledge beyond the experience of novice students, however. A simple example is presented which can illustrate that all may not be what it seems when energy transfer and the magnetic force are involved. Excel and Python simulations of the process are also provided.

State Department of Public Health v. Wells.

PubMed

1989-09-07

The Alabama Court of Civil Appeals decided that under state law the results of an inmate's HIV-AIDS test remain confidential. The release of test results may be done by physicians or state health officers to third parties where the risk of disease transmittal is foreseeable, real, or probable. An inmate awaiting transfer from a county jail to a state prison voluntarily submitted to HIV testing, and the county sheriff sought to compel release of the results. Under the state Notifiable Diseases Act, the county could not compel testing of those inmates awaiting transfer, nor could it compel release of the results of that testing. The results are confidential unless the test is compulsory or the inmate gives written consent, and then the discretion to divulge the results resides in physicians or state health personnel rather than in the courts.

The money blind: how to stop industry bias in biomedical science, without violating the First Amendment.

PubMed

Robertson, Christopher T

2011-01-01

The pharmaceutical and medical device industries use billions of dollars to support the biomedical science that physicians, regulators, and patients use to make healthcare decisions--the decisions that drive an increasingly large portion of the American economy. Compelling evidence suggests that this industry money buys favorable results, biasing the outcomes of scientific research. Current efforts to manage the problem, including disclosure mandates and peer reviews, are ineffective. A blinding mechanism, operating through an intermediary such as the National Institutes of Health, could instead be developed to allow industry support of science without allowing undue influence. If the editors of biomedical journals fail to mandate that industry funders utilize such a solution, the federal government has several regulatory levers available, including conditioning federal funding and direct regulation, both of which could be done without violating the First Amendment.

Do schizophrenia patients age early?

PubMed

Shivakumar, Venkataram; Kalmady, Sunil V; Venkatasubramanian, Ganesan; Ravi, Vasanthapuram; Gangadhar, Bangalore N

2014-08-01

The etiopathogenesis of schizophrenia is poorly understood. Within the proposed "neurodegeneration paradigm", observations have been put forth for "accelerated aging" in this disorder. This proposition is largely based on the neuroscience research that demonstrates progressive changes in brain as well as other systemic abnormalities supportive of faster aging process in patients with this disorder. In this review, we have summarized the literature related to the concept of early aging in schizophrenia. These studies include P300 abnormalities & visual motion discrimination, neuroimaging findings, telomere dynamics as well as neuropathology of related brain regions. We also propose a role of vitamin D, neuroimmunological changes and elevated oxidative stress as well as mitochondrial dysfunction in addition to the above factors with 'vitamin-D deficiency' as the central paradox. Put together, the evidence supporting early aging in schizophrenia is compelling and this requires further systematic studies. Copyright © 2014 Elsevier B.V. All rights reserved.

Civil society: the catalyst for ensuring health in the age of sustainable development.

PubMed

Smith, Julia; Buse, Kent; Gordon, Case

2016-07-16

Sustainable Development Goal Three is rightly ambitious, but achieving it will require doing global health differently. Among other things, progressive civil society organisations will need to be recognised and supported as vital partners in achieving the necessary transformations. We argue, using illustrative examples, that a robust civil society can fulfill eight essential global health functions. These include producing compelling moral arguments for action, building coalitions beyond the health sector, introducing novel policy alternatives, enhancing the legitimacy of global health initiatives and institutions, strengthening systems for health, enhancing accountability systems, mitigating the commercial determinants of health and ensuring rights-based approaches. Given that civil society activism has catalyzed tremendous progress in global health, there is a need to invest in and support it as a global public good to ensure that the 2030 Agenda for Sustainable Development can be realised.

Denham, Charles R; Guilloteau, Franck R

2012-09-01

The ultimate objective of this program is to provide an approach to understanding and communicating health-care harm and cost to compel health-care provider leadership teams to vote "yes" to investments in patient safety initiatives, with the confidence that clinical, financial, and operational performance will be improved by such programs. Through a coordinated combination of literature evaluations, careful mapping of high impact scenarios using simulated patients and consensus review of clinical, operational, and financial factors, we confirmed value in such approaches to decision support information for hospital leadership teams to invest in patient safety projects. The study resulted in the following preliminary findings: ·Communication between hospital quality and finance departments can be much improved by direct collaborative relationships through regular meetings to help both clarify direct costs, indirect costs, and the savings of waste and harm to patients by avoidance of infections. ·Governance leaders and the professional administrative leaders should consider establishing the structures and systems necessary to act on risks and hazards as they evolve to deploy resources to areas of harm and risk. ·Quality and Infection Control Professionals can best wage their war on healthcare waste and harm by keeping abreast of the latest literature regarding the latest measures, standards, and safe practices for healthcare-acquired infections and hospital-acquired conditions. ·Regular reviews of patients with health-careYassociated infections, with direct attention to the attributable cost of treatment and how financial waste and harm to patients may be avoided, may provide hospital leaders with new insights for improvement. ·If hospitals developed their own risk scenarios to determine impact of harm and waste from hospital-acquired conditions in addition to impact scenarios for specific processes through technology and process innovations, they would have more clear guidance for improvement efforts. ·Tools such as impact calculators, performance models, and simulated patient trajectories are no more tied to the reality of running a hospital or treating a patient as jet simulator metrics are to taking a real flight with real weather and real aircraftVthey provide a view to enhance decision making but do NOT provide the answers. The final result of this project was to demonstrate a prototype leadership decision-support investment model approach that addresses clinical, operational, and financial performance for typical hospitals.

A situational analysis of child-headed households in South Africa.

Mogotlane, S M; Chauke, M E; van Rensburg, G H; Human, S P; Kganakga, C M

2010-09-01

The aftermath of the HIV and AIDS pandemic has resulted in great suffering in terms of loss of income, poor quality of life, morbidity and mortality, with children being destitute and orphaned at an alarming rapid rate. Families and communities are currently unable to cope with the effects of HIV and AIDS with special emphasis on the care and support of the affected orphans and vulnerable children, who as a result have been compelled to look after themselves giving rise to a new type of family, the child-headed household. The emergence of this type of family requires government's response in terms of care and support. The purpose of this study was to provide a broad picture of the location, prevalence, composition, functions, needs and challenges of child-headed households in South Africa, and explore available and required services, resources and safety nets for children in child-headed households. An exploratory and descriptive design was used for the purpose. The sample consisted of children heading households and those living in the households that are headed by children; government departments responsible for child welfare, such as, the Departments of Social Development, Health, Education and Agriculture; non-profit organisations and communities where these households are predominant. From the data collected, it was found that the rights of the affected children were compromised. Those heading the households were often not at school and were responsible for domestic chores. The households needed food, clothes, money, shelter, and education. Government in attempting to address these needs required clear policies which will provide a distinction between orphaned and vulnerable children and child-headed households. The study recommended a collaborative approach as it was shown that there was no single model of best practice to appropriately and effectively address the needs of child-headed households.

Web tools for predictive toxicology model building.

2012-07-01

The development and use of web tools in chemistry has accumulated more than 15 years of history already. Powered by the advances in the Internet technologies, the current generation of web systems are starting to expand into areas, traditional for desktop applications. The web platforms integrate data storage, cheminformatics and data analysis tools. The ease of use and the collaborative potential of the web is compelling, despite the challenges. The topic of this review is a set of recently published web tools that facilitate predictive toxicology model building. The focus is on software platforms, offering web access to chemical structure-based methods, although some of the frameworks could also provide bioinformatics or hybrid data analysis functionalities. A number of historical and current developments are cited. In order to provide comparable assessment, the following characteristics are considered: support for workflows, descriptor calculations, visualization, modeling algorithms, data management and data sharing capabilities, availability of GUI or programmatic access and implementation details. The success of the Web is largely due to its highly decentralized, yet sufficiently interoperable model for information access. The expected future convergence between cheminformatics and bioinformatics databases provides new challenges toward management and analysis of large data sets. The web tools in predictive toxicology will likely continue to evolve toward the right mix of flexibility, performance, scalability, interoperability, sets of unique features offered, friendly user interfaces, programmatic access for advanced users, platform independence, results reproducibility, curation and crowdsourcing utilities, collaborative sharing and secure access.

Two routes to expertise in mental rotation.

PubMed

Provost, Alexander; Johnson, Blake; Karayanidis, Frini; Brown, Scott D; Heathcote, Andrew

2013-01-01

The ability to imagine objects undergoing rotation (mental rotation) improves markedly with practice, but an explanation of this plasticity remains controversial. Some researchers propose that practice speeds up the rate of a general-purpose rotation algorithm. Others maintain that performance improvements arise through the adoption of a new cognitive strategy-repeated exposure leads to rapid retrieval from memory of the required response to familiar mental rotation stimuli. In two experiments we provide support for an integrated explanation of practice effects in mental rotation by combining behavioral and EEG measures in a way that provides more rigorous inference than is available from either measure alone. Before practice, participants displayed two well-established signatures of mental rotation: Both response time and EEG negativity increased linearly with rotation angle. After extensive practice with a small set of stimuli, both signatures of mental rotation had all but disappeared. In contrast, after the same amount of practice with a much larger set both signatures remained, even though performance improved markedly. Taken together, these results constitute a reversed association, which cannot arise from variation in a single cause, and so they provide compelling evidence for the existence of two routes to expertise in mental rotation. We also found novel evidence that practice with the large but not the small stimulus set increased the magnitude of an early visual evoked potential, suggesting increased rotation speed is enabled by improved efficiency in extracting three-dimensional information from two-dimensional stimuli. © 2013 Cognitive Science Society, Inc.

Wyoming Landscape Conservation Initiative—A case study in partnership development

2016-10-21

The Wyoming Landscape Conservation Initiative (WLCI) is a successful example of collaboration between science and natural resource management at the landscape scale. In southwestern Wyoming, expanding energy and mineral development, urban growth, and other changes in land use over recent decades, combined with landscape-scale drivers such as climate change and invasive species, have presented compelling challenges to resource managers and a diverse group of Federal, State, industry, and non-governmental organizations, as well as citizen stakeholders. To address these challenges, the WLCI was established as a collaborative forum and interagency partnership to develop and implement science-based conservation actions. About a decade after being established, this report documents the establishment and history of the WLCI, focusing on the path to success of the initiative and providing insights and details that may be useful in developing similar partnerships in other locations. Not merely retrospective, the elements of the WLCI that are presented herein are still in play, still evolving, and still contributing to the resolution of compelling conservation challenges in the Western United States.The U.S. Geological Survey has developed many successful longstanding partnerships, of which the WLCI is one example.“As the Nation’s largest water, earth, and biological science and civilian mapping agency, the U.S. Geological Survey collects, monitors, analyzes, and provides scientific understanding about natural resource conditions, issues, and problems. The diversity of our scientific expertise enables us to carry out large-scale, multi-disciplinary investigations and provide impartial scientific information to resource managers, planners, and other customers” (U.S. Geological Survey, 2016).

Through the ages, men and women have cherished gold, and many have had a compelling desire to amass great quantities of it -- so compelling a desire, in fact, that the frantic need to seek and hoard gold has been aptly named "gold fever." Gold was among the first metals to be mined because it commonly occurs in its native form -- that is, not combined with other elements -- because it is beautiful and imperishable, and because exquisite objects can be made from it.

A compelling desire for deafness.

PubMed

Veale, David

2006-01-01

A case is described of a patient who has a compelling and persistent desire to become deaf. She often kept cotton wool moistened with oil in her ears and was learning sign language. Living without sound appeared to be a severe form of avoidance behavior from hyperacusis and misophonia. She had a borderline personality disorder that was associated with a poor sense of self. Her desire to be deaf may be one aspect of gaining an identity for herself and to compensate for feeling like an alien and gaining acceptance in the Deaf community. Will a compelling desire for deafness ever become a recognized mental disorder one day for which hearing patients may be offered elective deafness after a period of assessment and living like a deaf person? Those working in the field of deafness should be aware that individuals may occasionally be seeking elective deafness or self-inflicting deafness to obtain a hearing aid.

What adaptation to research is needed following crises: a comparative, qualitative study of the health workforce in Sierra Leone and Nepal.

Health workers are critical to the performance of health systems; yet, evidence about their coping strategies and support needs during and post crisis is lacking. There is very limited discussion about how research teams should respond when unexpected crises occur during on-going research. This paper critically presents the approaches and findings of two health systems research projects that explored and evaluated health worker performance and were adapted during crises, and provides lessons learnt on re-orientating research when the unexpected occurs. Health systems research was adapted post crisis to assess health workers' experiences and coping strategies. Qualitative in-depth interviews were conducted with 14 health workers in a heavily affected earthquake district in Nepal and 25 frontline health workers in four districts in Ebola-affected Sierra Leone. All data were transcribed and analysed using the framework approach, which included developing coding frameworks for each study, applying the frameworks, developing charts and describing the themes. A second layer of analysis included analysis across the two contexts, whereas a third layer involved the research teams reflecting on the approaches used to adapt the research during these crises and what was learned as individuals and research teams. In Sierra Leone, health workers were heavily stigmatised by the epidemic, leading to a breakdown of trust. Coping strategies included finding renewed purpose in continuing to serve their community, peer and family support (in some cases), and religion. In Nepal, individual determination, a sense of responsibility to the community and professional duty compelled staff to stay or return to their workplace. The research teams had trusting relationships with policy-makers and practitioners, which brought credibility and legitimacy to the change of research direction as well as the relationships to maximise the opportunity for findings to inform practice. In both contexts, health workers demonstrated considerable resilience in continuing to provide services despite limited support. Embedded researchers and institutions are arguably best placed to navigate emerging ethical and social justice challenges and are strategically positioned to support the co-production of knowledge and ensure research findings have impact.

The health benefits of dietary fiber in the general population are increasingly recognized. Krishnamurthy et al. provide compelling evidence that chronic kidney disease (CKD) further augments these benefits. CKD, besides a microinflammatory state, is a state of increased proteolytic fermentation. Both these harmful conditions are exacerbated by dietary protein and reversed by dietary fiber. Future nutrition guidelines should consider recommending a higher consumption of dietary fiber or potassium-free alternatives such as prebiotics in CKD patients.

Social values and the corruption argument against financial incentives for healthy behaviour.

PubMed

Brown, Rebecca C H

2017-03-01

Financial incentives may provide a way of reducing the burden of chronic diseases by motivating people to adopt healthy behaviours. While it is still uncertain how effective such incentives could be for promoting health, some argue that, even if effective, there are ethical objections that preclude their use. One such argument is made by Michael Sandel, who suggests that monetary transactions can have a corrupting effect on the norms and values that ordinarily regulate exchange and behaviour in previously non-monetised contexts. In this paper, I outline Sandel's corruption argument and consider its validity in the context of health incentives. I distinguish between two forms of corruption that are implied by Sandel's argument: efficiency corruption and value corruption While Sandel's thought-provoking discussion provides a valuable contribution to debates about health policies generally and health incentives specifically, I suggest the force of his criticism of health incentives is limited: further empirical evidence and theoretical reasoning are required to support the suggestion that health incentives are an inappropriate tool for promoting health. While I do not find Sandel's corruption argument compelling, this only constitutes a partial defence of health incentives, since other criticisms relating to their use may prove more successful.

Korean consumers' perceptions of health/functional food claims according to the strength of scientific evidence

PubMed Central

Kim, Ji Yeon; Kang, Eun Jin; Kwon, Oran

2010-01-01

In this study, we investigated that consumers could differentiate between levels of claims and clarify how a visual aid influences consumer understanding of the different claim levels. We interviewed 2,000 consumers in 13 shopping malls on their perception of and confidence in different levels of health claims using seven point scales. The average confidence scores given by participants were 4.17 for the probable level and 4.07 for the possible level; the score for the probable level was significantly higher than that for the possible level (P < 0.05). Scores for confidence in claims after reading labels with and without a visual aid were 5.27 and 4.43, respectively; the score for labeling with a visual aid was significantly higher than for labeling without a visual aid (P < 0.01). Our results provide compelling evidence that providing health claims with qualifying language differentiating levels of scientific evidence can help consumers understand the strength of scientific evidence behind those claims. Moreover, when a visual aid was included, consumers perceived the scientific levels more clearly and had greater confidence in their meanings than when a visual aid was not included. Although this result suggests that consumers react differently to different claim levels, it is not yet clear whether consumers understand the variations in the degree of scientific support.

Analgesic drug use and risk of epithelial ovarian cancer.

PubMed

Hannibal, Charlotte G; Rossing, Mary Anne; Wicklund, Kristine G; Cushing-Haugen, Kara L

2008-06-15

Analgesic use may reduce ovarian cancer risk, possibly through antiinflammatory or antigonadotropic effects. The authors conducted a population-based, case-control study in Washington State that included 812 women aged 35-74 years who were diagnosed with epithelial ovarian cancer between 2002 and 2005 and 1,313 controls. Use of analgesics, excluding use within the previous year, was assessed via in-person interviews. Logistic regression was used to calculate odds ratios and 95% confidence intervals. Overall, acetaminophen and aspirin were associated with weakly increased risks of ovarian cancer. These associations were stronger after more than 10 years of use (acetaminophen: odds ratio (OR) = 1.8, 95% confidence interval (CI): 1.3, 2.6; aspirin: OR = 1.6, 95% CI: 1.1, 2.2) and were present for indications of headache, menstrual pain, and other pain/injury. Reduced risk was observed among aspirin users who began regular use within the previous 5 years (OR = 0.6, 95% CI: 0.4, 1.0) or used this drug for prevention of heart disease (OR = 0.7, 95% CI: 0.5, 1.0). These results, in the context of prior findings, do not provide compelling evidence of a true increase in risk of ovarian cancer among women who use these drugs. However, they add to the weight of evidence that, in the aggregate, provides little support for the use of analgesic drugs as chemoprevention for this disease.

Addiction involves alterations in multiple brain regions that are associated with functions such as memory, motivation and executive control. Indeed, it is now well accepted that addictive drugs produce long-lasting molecular and structural plasticity changes in corticostriatal-limbic loops. However, there are brain regions that might be relevant to addiction other than the prefrontal cortex, amygdala, hippocampus and basal ganglia. In addition to these circuits, a growing amount of data suggests the involvement of the cerebellum in many of the brain functions affected in addicts, though this region has been overlooked, traditionally, in the addiction field. Therefore, in the present review we provide seven arguments as to why we should consider the cerebellum in drug addiction. We present and discuss compelling evidence about the effects of drugs of abuse on cerebellar plasticity, the involvement of the cerebellum in drug-induced cue-related memories, and several findings showing that the instrumental memory and executive functions also recruit the cerebellar circuitry. In addition, a hypothetical model of the cerebellum's role relative to other areas within corticostriatal-limbic networks is also provided. Our goal is not to review animal and human studies exhaustively but to support the inclusion of cerebellar alterations as a part of the physiopathology of addiction disorder.

Bergmann's Rule, Adaptation, and Thermoregulation in Arctic Animals: Conflicting Perspectives from Physiology, Evolutionary Biology, and Physical Anthropology After World War II.

PubMed

Hagen, Joel B

2017-05-01

Bergmann's rule and Allen's rule played important roles in mid-twentieth century discussions of adaptation, variation, and geographical distribution. Although inherited from the nineteenth-century natural history tradition these rules gained significance during the consolidation of the modern synthesis as evolutionary theorists focused attention on populations as units of evolution. For systematists, the rules provided a compelling rationale for identifying geographical races or subspecies, a function that was also picked up by some physical anthropologists. More generally, the rules provided strong evidence for adaptation by natural selection. Supporters of the rules tacitly, or often explicitly, assumed that the clines described by the rules reflected adaptations for thermoregulation. This assumption was challenged by the physiologists Laurence Irving and Per Scholander based on their arctic research conducted after World War II. Their critique spurred a controversy played out in a series of articles in Evolution, in Ernst Mayr's Animal Species and Evolution, and in the writings of other prominent evolutionary biologists and physical anthropologists. Considering this episode highlights the complexity and ambiguity of important biological concepts such as adaptation, homeostasis, and self-regulation. It also demonstrates how different disciplinary orientations and styles of scientific research influenced evolutionary explanations, and the consequent difficulties of constructing a truly synthetic evolutionary biology in the decades immediately following World War II.

Robust hippocampal responsivity during retrieval of consolidated associative memory.

2015-05-01

A contentious point in memory research is whether or not the hippocampus plays a time-limited role in the consolidation of declarative memories. A widely held view is that declarative memories are initially encoded in the hippocampus, then transferred to the neocortex for long-term storage. Alternate views argue instead that the hippocampus continues to play a role in remote memory recall. These competing theories are largely based on human amnesic and animal lesion/inactivation studies. However, in vivo electrophysiological evidence supporting these views is scarce. Given that other studies examining the role of the hippocampus in remote memory retrieval using lesion and imaging techniques in human and animal models have provided mixed results, it would be particularly useful to gain insight at the in vivo electrophysiological level. Here we report hippocampal single-neuron and theta activity recorded longitudinally during acquisition and remote retrieval of trace eyeblink conditioning. Results from conditioned rabbits were compared to those obtained from yoked pseudo-conditioned control rabbits. Results reveal continued learning-specific hippocampal activity one month after initial acquisition of the task. Our findings yield insight into the normal physiological responses of the hippocampus during memory processes and provide compelling in vivo electrophysiological evidence that the hippocampus is involved in both acquisition and retrieval of consolidated memories. © 2014 The Authors Hippocampus Published by Wiley Periodicals, Inc.

The value of health care information exchange and interoperability.

In this paper we assess the value of electronic health care information exchange and interoperability (HIEI) between providers (hospitals and medical group practices) and independent laboratories, radiology centers, pharmacies, payers, public health departments, and other providers. We have created an HIEI taxonomy and combined published evidence with expert opinion in a cost-benefit model. Fully standardized HIEI could yield a net value of dollar 77.8 billion per year once fully implemented. Nonstandardized HIEI offers smaller positive financial returns. The clinical impact of HIEI for which quantitative estimates cannot yet be made would likely add further value. A compelling business case exists for national implementation of fully standardized HIEI.

Developing Cognitive Models for Social Simulation from Survey Data

NASA Astrophysics Data System (ADS)

Alt, Jonathan K.; Lieberman, Stephen

The representation of human behavior and cognition continues to challenge the modeling and simulation community. The use of survey and polling instruments to inform belief states, issue stances and action choice models provides a compelling means of developing models and simulations with empirical data. Using these types of data to population social simulations can greatly enhance the feasibility of validation efforts, the reusability of social and behavioral modeling frameworks, and the testable reliability of simulations. We provide a case study demonstrating these effects, document the use of survey data to develop cognitive models, and suggest future paths forward for social and behavioral modeling.

Data from animal studies provide convincing evidence that physical exercise enhances brain development and neurobehavioral functioning in areas believed to be impaired in children with attention-deficit/hyperactivity disorder (ADHD). To a lesser but still compelling extent, results from studies in typically developing children and adults indicate beneficial effects of exercise on many of the neurocognitive functions that have been shown to be impaired in children with ADHD. Together, these data provide a strong rationale for why a program of structured physical exercise might serve as an effective intervention for children with ADHD. Copyright © 2014 Elsevier Inc.

NASA's MESSENGER Finds New Evidence for Water Ice at Mercury's Poles

NASA Image and Video Library

2017-12-08

New observations by the MESSENGER spacecraft provide compelling support for the long-held hypothesis that Mercury harbors abundant water ice and other frozen volatile materials in its permanently shadowed polar craters. Three independent lines of evidence support this conclusion: the first measurements of excess hydrogen at Mercury's north pole with MESSENGER's Neutron Spectrometer, the first measurements of the reflectance of Mercury's polar deposits at near-infrared wavelengths with the Mercury Laser Altimeter (MLA), and the first detailed models of the surface and near-surface temperatures of Mercury's north polar regions that utilize the actual topography of Mercury's surface measured by the MLA. These findings are presented in three papers published online today in Science Express. Given its proximity to the Sun, Mercury would seem to be an unlikely place to find ice. But the tilt of Mercury's rotational axis is almost zero — less than one degree — so there are pockets at the planet's poles that never see sunlight. Scientists suggested decades ago that there might be water ice and other frozen volatiles trapped at Mercury's poles. The idea received a boost in 1991, when the Arecibo radio telescope in Puerto Rico detected unusually radar-bright patches at Mercury's poles, spots that reflected radio waves in the way one would expect if there were water ice. Many of these patches corresponded to the location of large impact craters mapped by the Mariner 10 spacecraft in the 1970s. But because Mariner saw less than 50 percent of the planet, planetary scientists lacked a complete diagram of the poles to compare with the images. MESSENGER's arrival at Mercury last year changed that. Images from the spacecraft's Mercury Dual Imaging System taken in 2011 and earlier this year confirmed that radar-bright features at Mercury's north and south poles are within shadowed regions on Mercury's surface, findings that are consistent with the water-ice hypothesis.

The free neutron is an excellent laboratory for searches for physics beyond the standard model. Ultracold neutrons (UCN) are free neutrons that can be confined to material, magnetic, and gravitational traps. UCN are compelling for experiments requiring long observation times, high polarization, or low energies. The challenge of experiments has been to create enough UCN to reach the statistical precision required. Production techniques involving neutron interactions with condensed matter systems have resulted in some successes, and new UCN sources are being pursued worldwide to exploit higher UCN densities offered by these techniques. I will review the physics of how the UCN sources work, along with the present status of the world's efforts. research supported by NSERC, CFI, and CRC.

Release 0.0: clinical information technology in the real world.

Kleinke, J D

1998-01-01

The industrialization of medical care delivery, compelled by fifteen years of reimbursement reform, has given rise to a commercial health information technology (HIT) industry. Well financed by Wall Street, the HIT industry offers a variety of ready-made solutions designed to transform a health care organization's raw data resources into useful clinical information. Many of the resulting clinical decision-support products are encumbered by numerous insurmountable intellectual and technical problems and, as a consequence, meet with cultural resistance from physicians. The long-awaited but costly implementation of electronic medical records (EMRs) will make these pioneering but flawed efforts obsolete, if EMR development successfully exploits recent technological breakthroughs and the ongoing consolidation of health care organizations.

In the late phase of the HIV virus cycle, the unspliced genomic RNA is exported to the cytoplasm for the necessary translation of the Gag and Gag-pol polyproteins. Three distinct translation initiation mechanisms ensuring Gag production have been described with little rationale for their multiplicity. The Gag-IRES has the singularity to be located within Gag ORF and to directly interact with ribosomal 40S. Aiming at elucidating the specificity and the relevance of this interaction, we probed HIV-1 Gag-IRES structure and developed an innovative integrative modelling strategy to take into account all the gathered information. We propose a novel Gag-IRES secondary structure strongly supported by all experimental data. We further demonstrate the presence of two regions within Gag-IRES that independently and directly interact with the ribosome. Importantly, these binding sites are functionally relevant to Gag translation both in vitro and ex vivo. This work provides insight into the Gag-IRES molecular mechanism and gives compelling evidence for its physiological importance. It allows us to propose original hypotheses about the IRES physiological role and conservation among primate lentiviruses. © The Author(s) 2017.

Have We Vindicated the Motivational Unconscious Yet? A Conceptual Review

PubMed Central

Billon, Alexandre

2011-01-01

Motivationally unconscious (M-unconscious) states are unconscious states that can directly motivate a subject’s behavior and whose unconscious character typically results from a form of repression. The basic argument for M-unconscious states claims that they provide the best explanation for some seemingly non-rational behaviors, like akrasia, impulsivity, or apparent self-deception. This basic argument has been challenged on theoretical, empirical, and conceptual grounds. Drawing on recent works on apparent self-deception and on the “cognitive unconscious” I assess those objections. I argue that (i) even if there is a good theoretical argument for its existence, (ii) most empirical vindications of the M-unconscious miss their target. (iii) As for the conceptual objections, they compel us to modify the classical picture of the M-unconscious. I conclude that M-unconscious states and processes must be affective states and processes that the subject really feels and experiences – and which are in this sense conscious – even though they are not, or not well, cognitively accessible to him. Dual-process psychology and the literature on cold–hot empathy gaps partly support the existence of such M-unconscious states. PMID:21991258

Evaluating gender similarities and differences using metasynthesis.

Zell, Ethan; Krizan, Zlatan; Teeter, Sabrina R

2015-01-01

Despite the common lay assumption that males and females are profoundly different, Hyde (2005) used data from 46 meta-analyses to demonstrate that males and females are highly similar. Nonetheless, the gender similarities hypothesis has remained controversial. Since Hyde's provocative report, there has been an explosion of meta-analytic interest in psychological gender differences. We utilized this enormous collection of 106 meta-analyses and 386 individual meta-analytic effects to reevaluate the gender similarities hypothesis. Furthermore, we employed a novel data-analytic approach called metasynthesis (Zell & Krizan, 2014) to estimate the average difference between males and females and to explore moderators of gender differences. The average, absolute difference between males and females across domains was relatively small (d = 0.21, SD = 0.14), with the majority of effects being either small (46%) or very small (39%). Magnitude of differences fluctuated somewhat as a function of the psychological domain (e.g., cognitive variables, social and personality variables, well-being), but remained largely constant across age, culture, and generations. These findings provide compelling support for the gender similarities hypothesis, but also underscore conditions under which gender differences are most pronounced.

The Secrets of Great Teamwork.

Haas, Martine; Mortensen, Mark

2016-06-01

Over the years, as teams have grown more diverse, dispersed, digital, and dynamic, collaboration has become more complex. But though teams face new challenges, their success still depends on a core set of fundamentals. As J. Richard Hackman, who began researching teams in the 1970s, discovered, what matters most isn't the personalities or behavior of the team members; it's whether a team has a compelling direction, a strong structure, and a supportive context. In their own research, Haas and Mortensen have found that teams need those three "enabling conditions" now more than ever. But their work also revealed that today's teams are especially prone to two corrosive problems: "us versus them" thinking and incomplete information. Overcoming those pitfalls requires a new enabling condition: a shared mindset. This article details what team leaders should do to establish the four foundations for success. For instance, to promote a shared mindset, leaders should foster a common identity and common understanding among team members, with techniques such as "structured unstructured time." The authors also describe how to evaluate a team's effectiveness, providing an assessment leaders can take to see what's working and where there's room for improvement.

Airway Basal Cells. The “Smoking Gun” of Chronic Obstructive Pulmonary Disease

PubMed Central

2014-01-01

The earliest abnormality in the lung associated with smoking is hyperplasia of airway basal cells, the stem/progenitor cells of the ciliated and secretory cells that are central to pulmonary host defense. Using cell biology and ’omics technologies to assess basal cells isolated from bronchoscopic brushings of nonsmokers, smokers, and smokers with chronic obstructive pulmonary disease (COPD), compelling evidence has been provided in support of the concept that airway basal cells are central to the pathogenesis of smoking-associated lung diseases. When confronted by the chronic stress of smoking, airway basal cells become disorderly, regress to a more primitive state, behave as dictated by their inheritance, are susceptible to acquired changes in their genome, lose the capacity to regenerate the epithelium, are responsible for the major changes in the airway that characterize COPD, and, with persistent stress, can undergo malignant transformation. Together, these observations led to the conclusion that accelerated loss of lung function in susceptible individuals begins with disordered airway basal cell biology (i.e., that airway basal cells are the “smoking gun” of COPD, a potential target for the development of therapies to prevent smoking-related lung disorders).

The DoD investment of nominally $200 million per year is focused on four high power laser (HPL) concepts: Space-Based Laser (SBL), a Ballistic Missile Defense Organization effort that addresses boost-phase intercept for Theater Missile Defense and National Missile Defense; Airborne Laser (ABL), an Air Force effort that addresses boost-phase intercept for Theater Missile Defense; Ground-Based Laser (GBL), an Air Force effort addressing space control; and Anti-Ship Missile Defense (ASMD), a Navy effort addressing ship-based defense. Each organization is also supporting technology development with the goal of achieving less expensive, brighter, and lighter high power laser systems. These activities represent the building blocks of the DoD program to exploit the compelling characteristics of the high power laser. Even though DoD's HPL program are focused and moderately strong, additional emphasis in a few technical areas could help reduce risk in these programs. In addition, a number of options are available for continuing to use the High-Energy Laser System Test Facility (HELSTF) at White Sands Missile Range. This report provides a brief overview and guidance for the five efforts which comprise the DoD HPL program (SBL, ABL, GBL, ASMD, HELSTF).

Health Policy Training: A Review of the Literature

The context within which health care and public health systems operate is framed by health policies. There is growing consensus about the need for increased health policy leadership and a health professional workforce prepared to assume these leadership roles. At the same time, there is strong evidence supporting the need for a broader policy lens and the need to intentionally target health disparities. We reviewed the published literature between 1983 and 2013 regarding health policy training. From 5124 articles identified, 33 met inclusion criteria. Articles varied across common themes including target audience, goal(s), health policy definition, and core curricular content. The majority of articles were directed to medical or nursing audiences. Most articles framed health policy as health care policy and only a small number adopted a broader health in all policies definition. Few articles specifically addressed vulnerable populations or health disparities. The need for more rigorous research and evaluation to inform health policy training is compelling. Providing health professionals with the knowledge and skills to engage and take leadership roles in health policy will require training programs to move beyond their limited health care-oriented health policy framework to adopt a broader health and health equity in all policies approach.

Causes of death after fluid bolus resuscitation: new insights from FEAST.

PubMed

Myburgh, John; Finfer, Simon

2013-03-14

The Fluid Expansion as Supportive Therapy (FEAST study) was an extremely well conducted study that gave unexpected results. The investigators had reported that febrile children with impaired perfusion treated in low-income countries without access to intensive care are more likely to die if they receive bolus resuscitation with albumin or saline compared with no bolus resuscitation at all. In a secondary analysis of the trial, published in BMC Medicine, the authors found that increased mortality was evident in patients who presented with clinical features of severe shock in isolation or in conjunction with features of respiratory or neurological failure. The cause of excess deaths was primarily refractory shock and not fluid overload. These features are consistent with a potential cardiotoxic or ischemia-reperfusion injury following resuscitation with boluses of intravenous fluid. Although these effects may have been amplified by the absence of invasive monitoring, mechanical ventilation or vasopressors, the results provide compelling insights into the effects of intravenous fluid resuscitation and potential adverse effects that extend beyond the initial resuscitation period. These data add to the increasing body of literature about the safety and efficacy of intravenous resuscitation fluids, which may be applicable to management of other populations of critically ill patients.

Virtual worlds and avatars as the new frontier of telehealth care.

2012-01-01

We are entering a new age where people routinely visit, inhabit, play in and learn within virtual worlds (VWs). One in eight people worldwide are VW participants, according to the latest 2011 figures from KZERO [1]. VWs are also emerging as a new and advanced form of telehealth care delivery. In addition to existing telehealth care advantages; VWs feature three powerful affordances that can benefit a wide range of physical and psychological issues. First, the highly social nature of VWs encourages social networking and the formation of essential support groups. Secondly, the type of spaces that have been proven in the physical world to promote psychological health and well-being can be virtually recreated. Finally, research suggests that embodied avatar representation within VWs can affect users psychologically and physically. These three aspects of VWs can be leveraged for enhanced patient-client interactions, spaces that promote healing and positive responses, and avatar activities that transfer real benefits from the virtual to the physical world. This paper explains the mounting evidence behind these claims and provides examples of VWs as an innovative and compelling form of telehealth care destined to become commonplace in the future.

Economic Dependence of U.S. Industrial Sectors on Animal-Mediated Pollination Service.

Declining animal pollinator health and diversity in the U.S. is a matter of growing concern and has particularly gained attention since the emergence of colony collapse disorder (CCD) in 2006. Failure to maintain adequate animal-mediated pollination service to support increasing demand for pollination-dependent crops poses risks for the U.S. economy. We integrate the Economic Input-Output (EIO) model and network analysis with data on pollinator dependence of crops to understand the economic dependence of U.S. industrial sectors on animal-mediated pollination service. The novelty of this work lies in its ability to identify industrial sectors and industrial communities (groups of closely linked sectors) that are most vulnerable to scarcity of pollination service provided by various animal species. While the economic dependence of agricultural sectors on pollination service is significant (US$14.2-23.8 billion), the higher-order economic dependence of the rest of the U.S. industrial sectors is substantially high as well (US$10.3-21.1 billion). The results are compelling as they highlight the critical importance of animal-induced pollination service for the U.S. economy, and the need to account for the role of ecosystem goods and services in product life cycles.

The Elbmarsch leukemia cluster: are there conceptual limitations in controlling immission from nuclear establishments in Germany?

The childhood leukemia cluster in the proximity of the German nuclear establishments of Geesthacht is unique in its spatial and temporal concentration. After a steep increase in cases in 1990, the cluster continues to show a significant increase up to the present. Early investigations of blood samples from a casual sample of local residents showed an increase in dicentric chromosomes in lymphocytes, indicating exposure exceeding dose limits. Analyses of the immission data revealed several unexpected deliveries of fission and activation products in the environment but provided no explanation of the source. Because of the observed overdispersion of dicentric chromosomes in cells, the idea of a contribution by densely ionizing emitters was compelling. The routine programs, however, do not include alpha emitters. These were measured in specific studies that proved contamination by transuranic nuclides. As shown in the present investigation, routine environmental surveillance programs support the occurrence of an accidental event near Geesthacht in September 1986. Until now, neither the cause nor the complete scenario of the activity release could be established. The ongoing discussion highlights limitations in the immission-control concept, which is predominantly based on gamma-radiation monitoring.

A longitudinal test of video game violence influences on dating and aggression: a 3-year longitudinal study of adolescents.

2012-02-01

In 2011 the field of video game violence experienced serious reversals with repudiations of the current research by the US Supreme Court and the Australian Government as non-compelling and fundamentally flawed. Scholars too have been calling for higher quality research on this issue. The current study seeks to answer this call by providing longitudinal data on youth aggression and dating violence as potential consequences of violent video game exposure using well-validated clinical outcome measures and controlling for other relevant predictors of youth aggression. A sample of 165, mainly Hispanic youth, were tested at 3 intervals, an initial interview, and 1-year and 3-year intervals. Results indicated that exposure to video game violence was not related to any of the negative outcomes. Depression, antisocial personality traits, exposure to family violence and peer influences were the best predictors of aggression-related outcomes. The current study supports a growing body of evidence pointing away from video game violence use as a predictor of youth aggression. Public policy efforts, including funding, would best be served by redirecting them toward other prevention programs for youth violence. Copyright © 2011 Elsevier Ltd. All rights reserved.

Decreases in tanning behaviors following a short online survey: Potential for prevention?

To date, tanning prevention programs have led to limited success. The aim of the present study was to investigate potential unexpected prevention effects of completing an online survey focused on tanning attitudes, behaviors, and knowledge among female college tanners. A sample of 92 female undergraduate students from the USA, mean age = 20.09, SD = 1.41 years, who engaged in indoor tanning completed an online survey assessing awareness of tanning-related health risks, appearance-based motivations to tan and not to tan, media literacy related to tanning marketing, and tanning behaviors in 2013. Four months later, participants were invited to complete a follow-up survey assessing tanning intentions and behaviors since completing the initial survey. Fifty-one participants (55%) completed the follow-up questions, of whom 43 (84.3%) reported having decreased or ceased engaging in indoor tanning. In addition participants provided comments indicating that completing the survey had lead to decreases in their tanning behaviors. Our study presents novel and compelling support for using brief online surveys for decreasing health-risk behaviors such as sunbed use. Such measures are extremely cost-effective and easy to disseminate and implement. Replication and extension of these findings are warranted.

Cretaceous Footprints Found on Goddard Campus

The entire find, containing at least three dinosaur footprints, is approximately seven feet long and three feet across at its widest point. Additionally, the footprint-rich layer is bonded to a separate layer of iron-rich sandstone that complicated the efforts to extract and preserve it. Before removing the rock layer, Godfrey made a silicon-rubber cast of the prints, then jacketed the entire find in multiple layers of plaster-soaked burlap (i.e. just like a cast) to add rigidity and to further ward against breakage during transport. Galvanized steel pipes wrapped into the jacket acted like splints to provide additional structural support. The combined weight of the footprint, field jacket material and surrounding soil that was removed was estimated to be approximately 3,000 pounds, so extra care was taken in moving it to avoid damaging the rather extraordinary find.

NIST activities in support of space-based radiometric remote sensing

NASA Astrophysics Data System (ADS)

Rice, Joseph P.; Johnson, B. Carol

2001-06-01

We provide an historical overview of NIST research and development in radiometry for space-based remote sensing. The applications in this field can be generally divided into two areas: environmental and defense. In the environmental remote sensing area, NIST has had programs with agencies such as the National Aeronautical and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) to verify and improve traceability of the radiometric calibration of sensors that fly on board Earth-observing satellites. These produce data used in climate models and weather prediction. Over the years, the scope of activities has expanded from existing routine calibration services for artifacts such as lamps, diffusers, and filters, to development and off-site deployment of portable radiometers for radiance- and irradiance-scale intercomparisons. In the defense remote sensing area, NIST has had programs with agencies such as the Department of Defense (DOD) for support of calibration of small, low-level infrared sources in a low infrared background. These are used by the aerospace industry to simulate ballistic missiles in a cold space background. Activities have evolved from calibration of point-source cryogenic blackbodies at NIST to measurement of irradiance in off-site calibration chambers by a portable vacuum/cryogenic radiometer. Both areas of application required measurements on the cutting edge of what was technically feasible, thus compelling NIST to develop a state-of-the-art radiometric measurement infrastructure to meet the needs. This infrastructure has led to improved dissemination of the NIST spectroradiometric quantities.

Healthcare e-commerce: connecting with patients.

Electronically connecting with patients is a challenging frontier at which technical hurdles are probably exceeded by political, legal, and other barriers. The rise of consumerism, however, compels a response focused more on revenue and strategic advantage than on pure cost savings. Among the difficulties faced by providers is choosing among various models of connectivity and component function. Emerging models include "free-floating" personal medical records largely independent of the office-based physician, systems with compatible and intertwined physician and consumer relationships using an application services provider office practice system, and systems that connect patients and providers through e-mail, office triage, prescription refills, scheduling, and so on. This article discusses these and other combinations of technology that significantly overcome the barriers involved and that may be woven together to provide solutions uniquely suited to various competitive situations.

The design philosophy that will guide the design of early lunar habitats will be based on a compromise between the desired capabilities of the base and the economics of its development and implantation. Preferred design will be simple, make use of existing technologies, require the least amount of lunar surface preparation, and minimize crew activity. Three concepts for an initial habitat supporting a crew of four for 28 to 30 days are proposed. Two of these are based on using Space Station Freedom structural elements modified for use in a lunar-gravity environment. A third concept is proposed that is based on an earlier technology based on expandable modules. The expandable modules offer significant advantages in launch mass and packaged volume reductions. It appears feasible to design a transport spacecraft lander that, once landed, can serve as a habitat and a stand-off for supporting a regolith environmental shield. A permanent lunar base habitat supporting a crew of twelve for an indefinite period can be evolved by using multiple initial habitats. There appears to be no compelling need for an entirely different structure of larger volume and increased complexity of implantation.

The evidence supporting benefits of physical activity (PA) on fitness, functioning, health and secondary prevention after stroke is compelling. However, many stroke survivors remain insufficiently active. This study explored survivors' perspectives and experiences of PA participation to develop an explanatory framework that physiotherapists and other health professionals can use to develop person-specific strategies for PA promotion. Qualitative study using semi-structured in-depth interviews. Data was audio-recorded and transcribed. Analysis followed the Framework Approach. Community setting, interviews conducted within participants' homes. Community dwelling stroke survivors (n=38) six months or more after the end of their rehabilitation, purposively selected by disability, PA participation and socio-demographic status. Findings suggest that survivors' beliefs, attitudes, and physical and social context generated synergy or dissonance between motivation (desire to be active) and capability (resources to be active) for PA participation. Dissonance occurred when motivated survivors had limited capability for activity, often leading to frustration. Confidence to achieve goals and determination to overcome barriers, acted as activity catalysts when other influences were synergistic. We illustrate these relationships in a dynamic explanatory model that can be used to support both novel interventions and personal activity plans. This study suggests a shift is required from purely pragmatic approaches to PA promotion towards conceptual solutions. Understanding how synergy or dissonance between motivation and capability influence individual survivors' behaviour will support physiotherapists and other health professionals in promoting PA. This study provides a model for developing person-centred, tailored interventions that address barriers encountered by stroke survivors. Copyright © 2016 Chartered Society of Physiotherapy.

Rapid increase in the incidence of type 2 diabetes (DM2) in Papua New Guinea, coupled with compelling epidemiological evidence supporting a diabetogenic association with betel quid (BQ) chewing has lead us to investigate dietary strategies that might offer protection from developing DM2. We investigated the dietary habits of Kalo residents from coastal Central Province who are avid BQ chewers yet have a relatively low incidence of DM2 compared to the ethnically similar and adjacent Wanigelans who abstain from BQ yet have an unusually high incidence of DM2. In Kalo, guava bud (Psidium guajava L) and noni (Morinda citrifolia L) were consumed much more frequently than in Wanigela, whereas the inverse was observed for mangrove bean (Bruguiera gymnorrhiza (L) Lam.). These plants, along with BQ and its component ingredients areca nut (Areca catechu L) and Piper betle L inflorescence, were assessed for their ability to mediate insulin-dependent and insulin-independent glucose transport in cultured 3T3-L1 adipocytes. A dose-dependent inhibition of glucose uptake from methanolic extracts of BQ, areca nut and P. betle inflorescence supports previous reports of prodiabetic activity. Conversely, guava bud extract displayed significant insulin-mimetic and potentiating activity. Noni fruit, noni leaf, commercial noni juice and mangrove bean all displayed insulin-like activity but had little or no effect on insulin action. Habitual intake of guava and noni is proposed to offer better protection against DM2 development and/or betel quid diabetogenicity than cooked mangrove bean. These findings provide empirical support that DM2 risk reduction can be accomplished using traditional foods and medicines.

Impact of social norms and social support on diet, physical activity and sedentary behaviour of adolescents: a scoping review.

The prevalence of non-communicable diseases (NCDs) in adulthood is rapidly increasing, and it is essential that risk factors for NCDs be addressed in adolescence, both for the health of individuals during adolescence and for their health in later life. These risk factors include diet, physical activity and sedentary behaviour. No literature has been published that comprehensively summarizes the impact of social norms and social support on these behaviours among adolescents. Therefore, a scoping review was conducted to determine the extent of recent (since 2000) literature available on this topic. A comprehensive search strategy was used to search PubMed and EMBASE for eligible reviews. Review papers (narrative reviews, systematic and non-systematic reviews) published in English in peer-reviewed journals from 2000 to February 2013 were included in the overview. Two of the authors screened the titles and abstracts of the search results independently. Thirty reviews were included in the scoping review. This scoping review has shown sufficient evidence for parental influences, and especially the positive impact of an authoritative parenting style, on healthy behaviours of adolescents, although the evidence is somewhat more compelling for diet than for physical activity and sedentary behaviour. More research is needed to investigate parental and family influences on physical activity and sedentary behaviour. And the effect of peer influences on diet, physical activity and sedentary behaviour of adolescents requires further investigation. The evidence presented affirms the consideration of social norms and social support in the development of interventions to address these behaviours in adolescents. The evidence regarding parenting style provides some concrete guidance for such interventions. © 2015 John Wiley & Sons Ltd.

Current strategies for improving access and adherence to antiretroviral therapies in resource-limited settings

Scanlon, Michael L; Vreeman, Rachel C

2013-01-01

The rollout of antiretroviral therapy (ART) significantly reduced human immunodeficiency virus (HIV)-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world’s HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation. Findings from this review make a compelling case for more data to guide strategies to improve access and adherence to treatment in resource-limited settings. PMID:23326204

UNDERSTANDING X-RAY STARS:. The Discovery of Binary X-ray Sources

NASA Astrophysics Data System (ADS)

Schreier, E. J.; Tananbaum, H.

2000-09-01

The discovery of binary X-ray sources with UHURU introduced many new concepts to astronomy. It provided the canonical model which explained X-ray emission from a large class of galactic X-ray sources: it confirmed the existence of collapsed objects as the source of intense X-ray emission; showed that such collapsed objects existed in binary systems, with mass accretion as the energy source for the X-ray emission; and provided compelling evidence for the existence of black holes. This model also provided the basis for explaining the power source of AGNs and QSOs. The process of discovery and interpretation also established X-ray astronomy as an essential sub-discipline of astronomy, beginning its incorporation into the mainstream of astronomy.

A Marine Origin for the Meridiani Planum Landing Site?

2005-01-01

The Opportunity instruments have provided compelling evidence that the sulfate-rich chemical and siliciclastic sediments at the Meridiani Planum landing site were deposited in shallow water. The local paleo-environment is most often characterized as a broad, shallow sea or large playa, with surface conditions cycling between wet and dry episodes, interbedding evaporates with eolian fine sediments [e.g., 1,2]. This particular working hypothesis is reasonable, considering the area characterized by the rover s mobility. An alternative, marine origin will be considered here, a working hypothesis that we feel provides a better fit to the local-scale results identified by Opportunity, and the regional-scale characteristics of Meridiani Planum provided by data from orbiting spacecraft, when considered together.

Background A recent clinical trial demonstrated that a daily dose tenofovir disoproxil fumarate and emtricitabrine (TDF-FTC) can reduce HIV acquisition among men who have sex with men (MSM) and transgender (TG) women by 44%, and up to 90% if taken daily. We explored how medical and service providers understand research results and plan to develop clinical protocols to prescribe, support and monitor adherence for patients on PrEP in the United States. Methods Using referrals from our community collaborators and snowball sampling, we recruited 22 healthcare providers in San Francisco, Oakland, and Los Angeles for in-depth interviews from May-December 2011. The providers included primary care physicians seeing high numbers of MSM and TG women, HIV specialists, community health clinic providers, and public health officials. We analyzed interviews thematically to produce recommendations for setting policy around implementing PrEP. Interview topics included: assessing clinician impressions of PrEP and CDC guidance, considerations of cost, office capacity, dosing schedules, and following patients over time. Results Little or no demand for PrEP from patients was reported at the time of the interviews. Providers did not agree on the most appropriate patients for PrEP and believed that current models of care, which do not involve routine frequent office visits, were not well suited for prescribing PrEP. Providers detailed the need to build capacity and were concerned about monitoring side effects and adherence. PrEP was seen as potentially having impact on the epidemic but providers also noted that community education campaigns needed to be tailored to effectively reach specific vulnerable populations. Conclusions While PrEP may be a novel and clinically compelling prevention intervention for MSM and TG women, it raises a number of important implementation challenges that would need to be addressed. Nonetheless, most providers expressed optimism that they eventually could prescribe and monitor PrEP in their practice. PMID:22792384

Intellectual disability (ID) is a common morbid condition with a wide range of etiologies. The list of monogenic forms of ID has increased rapidly in recent years thanks to the implementation of genomic sequencing techniques. In this study, we describe the phenotypic and genetic findings of 68 families (105 patients) all with novel ID-related variants. In addition to established ID genes, including ones for which we describe unusual mutational mechanism, some of these variants represent the first confirmatory disease-gene links following previous reports (TRAK1, GTF3C3, SPTBN4 and NKX6-2), some of which were based on single families. Furthermore, we describe novel variants in 14 genes that we propose as novel candidates (ANKHD1, ASTN2, ATP13A1, FMO4, MADD, MFSD11, NCKAP1, NFASC, PCDHGA10, PPP1R21, SLC12A2, SLK, STK32C and ZFAT). We highlight MADD and PCDHGA10 as particularly compelling candidates in which we identified biallelic likely deleterious variants in two independent ID families each. We also highlight NCKAP1 as another compelling candidate in a large family with autosomal dominant mild intellectual disability that fully segregates with a heterozygous truncating variant. The candidacy of NCKAP1 is further supported by its biological function, and our demonstration of relevant expression in human brain. Our study expands the locus and allelic heterogeneity of ID and demonstrates the power of positional mapping to reveal unusual mutational mechanisms.

The ethics of placebo-controlled trials: methodological justifications.

Millum, Joseph; Grady, Christine

2013-11-01

The use of placebo controls in clinical trials remains controversial. Ethical analysis and international ethical guidance permit the use of placebo controls in randomized trials when scientifically indicated in four cases: (1) when there is no proven effective treatment for the condition under study; (2) when withholding treatment poses negligible risks to participants; (3) when there are compelling methodological reasons for using placebo, and withholding treatment does not pose a risk of serious harm to participants; and, more controversially, (4) when there are compelling methodological reasons for using placebo, and the research is intended to develop interventions that can be implemented in the population from which trial participants are drawn, and the trial does not require participants to forgo treatment they would otherwise receive. The concept of methodological reasons is essential to assessing the ethics of placebo controls in these controversial last two cases. This article sets out key considerations relevant to considering whether methodological reasons for a placebo control are compelling. © 2013.

The Influence of Social Networks and Social Support on Health Among Older Koreans at High Risk of Depression.

PubMed

Chung, Soondool; Jeon, Haesang; Song, Ahyoung

Despite compelling evidence showing that social networks and social support are associated with depression, relatively little research is available on this topic for older Koreans at high risk of depression. This article aimed to examine the relationship among different types of social networks (family vs. friends), social support (instrumental vs. emotional), and perceived general health among older Koreans at high risk of depression. We would then test for possible differences in pathways between two age groups (60-74 years vs. 75 years and older). Using data from the 2008 Survey of Elderly Life and Welfare Need, age 60-74 years (n = 2,815) and age 75 years and older (n = 1,784) were analyzed separately. Path analyses were used to examine the relationships among social network, support, and health among Korean older adults at high risk of depression. Findings highlighted the complex associations among social networks, social support, and perceived general health within old age. Moreover, this study called attention to the negative association between instrumental support from family networks and perceived general health among older Koreans aged 60-74 years at high risk of depression. The work discussed in this article would help inform the design of much needed and effective social intervention programs for the growing number of Korean older adults with depression.

The ethics of stem cells revisited.

Stem cells constitute one of the most promising tools for regenerative medicine. Thus, it seems morally compelling to explore all the sources that might provide us with them. However, some of these sources, such as somatic cell nuclear transfer, embryo destruction, or even induced pluripotency obtained by reprogramming have raised deep ethical issues. The aim of this paper is to reflect on the stem cell ethical debate at the current moment through an analysis of the academic literature. It will also provide an analysis of the ethical implications of the most relevant scientific advances that have happened in recent months or those which seem about to merge.

Science fiction on television and in movies reaches a wide audience of young people. Some of them are avid fans of particular stories, and more are enthralled by some of the special effects and other science fiction themes that have become ever more compelling as media technology improves. It actually doesn't matter whether the physics behind the science fiction is solid, the latest in speculative theory, or absolute nonsense - all provide a backdrop against which to present solid science. I'll talk about the opportunities provided by a few recent series and movies and how they can be woven into discussions of physics, astrophysics, or how science really works.

2004-01-01

Despite a compelling body of published research on the nature of provider volume and clinical outcomes, healthcare executives and policymakers have not managed to develop and implement systems that are useful in directing patients to higher volume providers via selective referral or avoidance. A specialized data warehouse application, utilizing hospital discharge data linked to physician biographical information, allows detailed analysis of physician and hospital volume and the resulting pattern (contour) of related outcomes such as mortality, complications, and medical errors. The approach utilizes a historical repository of hospital discharge data in which the outcomes of interest, important patient characteristics and risk factors used in severity-adjusting of the outcomes are derived from the coding structure of the data.

The Role of Reconciling Values in Efforts to Build Community Resilience to Global Environmental Change

Rainie, S. C.; Ferguson, D. B.; Martinez, A.

2017-12-01

Global environmental change has increasingly forced researchers and policy makers to reckon with the practical and philosophical need to integrate Indigenous knowledge with western science to support sustainable, resilient communities. Despite the recognition that integration of different ways of knowing offers a compelling approach for building long-term resilience, balancing the power dynamic that favors mainstream epistemologies over other ways of knowing remains elusive. Indigenous scholars themselves often speak of "walking in two worlds," acknowledging the distinction between Indigenous knowledge and western science and the difficulty of weaving together the two approaches. Central to the distinction between different ways of knowing are the core values that drive development and application of new knowledge. The DIKW pyramid describes the hierarchical relationships between wisdom, knowledge, information, and data. In these relationships, values drive how one turns data into information, then knowledge and wisdom. Thus, if building community resilience relies on integrating Indigenous science and Western science, a central point of focus must be on establishing which of the core values from these different knowledge systems can contribute and which may impede the goal of supporting community resilience. For example, does the absence of Western science data collection protocols (a core value of empirical science) eliminate the utility of community observations of environmental change from efforts to understand system change? Indigenous data sovereignty, an emerging framework, asserts Indigenous rights to information and promotes the role of community knowledge in creating metrics, outcomes, and ultimately actions toward resilient communities. Indigenous data sovereignty acknowledges that context and values shape data in addition to providing a lens for interpreting data. Can principles for the governance of Indigenous data, such as recognizing and supporting Indigenous ways of knowing begin to balance the power dynamic? Building on the authors' experiences, theories of resilience, and Indigenous data sovereignty frameworks this presentation will address the question: How can values from different knowledge systems be aligned to support long-term community resilience?

Self-management education for cardiopulmonary diseases is primarily provided through time-limited, face-to-face programs, with access limited to a small percentage of patients. Telecommunication tools will increasingly be an important component of future health care delivery. The purpose of this study was to describe the patterns of technology use in patients attending a cardiopulmonary clinic in an academic medical center. A prevalence survey was developed to collect data on participant demographics (age in years, sex, and socioeconomic status); access to computers, Internet, and mobile phones; and use of current online health support sites or programs. Surveys were offered by reception staff to all patients attending the outpatient clinic. A total of 123 surveys were collected between March and April 2014. Technological devices were a pervasive part of everyday life with respondents engaged in regular computer (102/123, 82.9%), mobile telephone (115/117, 98.3%), and Internet (104/121, 86.0%) use. Emailing (101/121, 83.4%), researching and reading news articles (93/121, 76.9%), social media (71/121, 58.7%), and day-to-day activities (65/121, 53.7%) were the most common telecommunication activities. The majority of respondents reported that access to health support programs and assistance through the Internet (82/111, 73.9%) would be of use, with benefits reported as better understanding of health information (16/111, 22.5%), avoidance of difficult travel requirements and time-consuming face-to-face appointments (13/111, 18.3%), convenient and easily accessible help and information (12/111, 16.9%), and access to peer support and sharing (9/111, 12.7%). The majority of patients did not have concerns over participating in the online environment (87/111, 78.4%); the few concerns noted related to privacy and security (10/15), information accuracy (2/15), and computer literacy and access (2/15). Chronic disease burden and long-term self-management tasks provide a compelling argument for accessible and convenient avenues to obtaining ongoing treatment and peer support. Online access to health support programs and assistance was reported as useful and perceived as providing convenient, timely, and easily accessible health support and information. Distance from the health care facility and a lack of information provision through traditional health sources were both barriers and enablers to telehealth. This is particularly important in the context of a cardiopulmonary clinic that attracts patients from a large geographical area, and in patients who are most likely to have high health care utilization needs in the future. Telecommunication interfaces will be an increasingly important adjunct to traditional forms of health care delivery.
