Waiting for oblivion: women's experiences with electroshock.

PubMed

Leslie van Daalen-Smith, Cheryl

2011-01-01

This article presents findings and analysis stemming from a two-year qualitative study that explored, in their own voices, women's lived experience of electroshock. Feminist standpoint theory frames and provides the moorings for both the validity and methodology of this woman-centered inquiry. In addition, nurses' experiences with and views of ECT are explored and compared to the experiences reported by the women recipients themselves. Vulnerability and disconnection as emergent themes are presented for the nursing profession's sober consideration. The nurses interviewed believed electroshock culminated in a net gain for patients, but for the majority of the women interviewed, electroshock resulted in damage and devastating loss. This article closes with pressing questions for nurses to ask ourselves as we enter the second decade of this new and promising millennium.

‘It makes you think’ – exploring the impact of qualitative films on pain clinicians

PubMed Central

Jenkins, Sue

2015-01-01

Background: Researchers need to consider the impact and utility of their findings. Film is an accessible medium for qualitative research findings and can facilitate learning through emotional engagement. Aim: We aimed to explore the usefulness of a short film presenting findings from a published qualitative synthesis of adults’ experience of chronic musculoskeletal pain for pain education. In particular, we were interested in the impact of the film on clinician’s understanding of patients’ experience of chronic pain and how this knowledge might be used for improved healthcare for people with pain. Methods: Focus groups with healthcare professionals enrolled in a pain management foundation course explored healthcare professionals’ experience of watching the film. A constructivist grounded theory approach was adopted by the researchers. Findings: This article presents one thematic exemplar from a wider study. Participants reflected upon the pitfalls of judging by appearances and the value of seeing the person beneath his or her performance. Conclusion: There is a danger that the impact of qualitative findings is under-valued in clinical education. We present one exemplar from a study exploring knowledge mobilisation, which demonstrates that qualitative research, specifically qualitative films, can make us think about the care that we provide to people with chronic pain.

Embodied female experience through the lens of imagination.

PubMed

Green, Sharon R

2010-06-01

In 1971, I made a film entitled Self Portrait of a Nude Model Turned Cinematographer in which I explore the objectifying 'male' gaze on my body in contrast to the subjective lived experience of my body. The film was a radical challenge to the gaze that objectifies woman - and thus imprisons her - which had hitherto dominated narrative cinema. Since the objectification of women has largely excluded us from the privileged phallogocentric discourses, in this paper I hope to bring into the psychoanalytic dialogue a woman's lived experience. I will approach this by exploring how remembering this film has become a personally transformative experience as I look back on it through the lens of postmodern and feminist discourses that have emerged since it was made. In addition, I will explore how this process of imaginatively looking back on an artistic creation to generate new discourses in the present is similar to the transformative process of analysis. Lastly, I will present a clinical example, where my embodied countertransference response to a patient's subjection to the objectifying male gaze opens space for a new discourse about her body to emerge.

2005-01-01

The Mars Exploration Rovers each carry a set of Magnetic Properties Experiments designed to investigate the properties of the airborne dust in the Martian atmosphere. It is a preferred interpretation of previous experiments that the airborne dust in the Martian atmosphere is primarily composed by composite silicate particles containing one or more highly magnetic minerals as a minor constituent. The ultimate goal of the magnetic properties experiments on the Mars Exploration Rover mission is to provide some information/ constraints on whether the dust is formed by volcanic, meteoritic, aqueous, or other processes. The first problem is to identify the magnetic mineral(s) in the airborne dust on Mars. While the overall results of the magnetic properties experiments are presented in, this abstract will focus on dust deposition and dust removal on some of the magnets.

Culture, personal experience and agency.

PubMed

McCarthy, John; Sullivan, Paul; Wright, Peter

2006-06-01

In this article, we explore what we perceive to be a gap between agency as articulated in practice theories and agency as personally experienced. The gap is not created by a turn to practice in theorizing, but by the tendency to produce theoretical representations that silence the particularity of experience and the diversity of voices in experience. In exploring the gap, we identify aspects of practice theories that explicitly commit to theoretical representation over personal experience and describe Bakhtin's commitment to action and personal experience as an alternative. In order to exemplify Bakhtin's approach in practice, we then present an analysis of one artist-teacher's experience of her own agency in making art and in teaching. Finally, we comment on what a commitment to representational theorizing does to accounts of an artist's activities and personal experience.

CET exSim: mineral exploration experience via simulation

NASA Astrophysics Data System (ADS)

Wong, Jason C.; Holden, Eun-Jung; Kovesi, Peter; McCuaig, T. Campbell; Hronsky, Jon

2013-08-01

Undercover mineral exploration is a challenging task as it requires understanding of subsurface geology by relying heavily on remotely sensed (i.e. geophysical) data. Cost-effective exploration is essential in order to increase the chance of success using finite budgets. This requires effective decision-making in both the process of selecting the optimum data collection methods and in the process of achieving accuracy during subsequent interpretation. Traditionally, developing the skills, behaviour and practices of exploration decision-making requires many years of experience through working on exploration projects under various geological settings, commodities and levels of available resources. This implies long periods of sub-optimal exploration decision-making, before the necessary experience has been successfully obtained. To address this critical industry issue, our ongoing research focuses on the development of the unique and novel e-learning environment, exSim, which simulates exploration scenarios where users can test their strategies and learn the consequences of their choices. This simulator provides an engaging platform for self-learning and experimentation in exploration decision strategies, providing a means to build experience more effectively. The exSim environment also provides a unique platform on which numerous scenarios and situations (e.g. deposit styles) can be simulated, potentially allowing the user to become virtually familiarised with a broader scope of exploration practices. Harnessing the power of computer simulation, visualisation and an intuitive graphical user interface, the simulator provides a way to assess the user's exploration decisions and subsequent interpretations. In this paper, we present the prototype functionalities in exSim including: simulation of geophysical surveys, follow-up drill testing and interpretation assistive tools.

The organisation of musical semantic memory: evidence from false memories for familiar songs.

PubMed

Sherman, Susan M; Kennerley, Jo

2014-01-01

By adapting a well-known paradigm for studying memory for words-the Deese-Roediger-McDermott or DRM paradigm (Deese, 1959, Roediger & McDermott, 1995)-the two experiments reported here explore memory for song titles and song clips. Participants were presented with five song titles (Experiment 1a) or five 30-second song clips (Experiment 1b) for each of nine popular artists (e.g., Robbie Williams). The most popular song identified for each artist in a pilot task was omitted from the sets of titles/clips. Following a distractor task, participants were asked to write down as many of the songs as they could recall. They were also asked to return a week later and complete a second recall task. Participants falsely recalled a significant number of the related but non-presented songs in both experiments and this increased a week later, while correct recall for presented items decreased. The results are discussed in terms of theory for musical memory as well as in the context of providing a novel method for exploring the organisation of musical memory.

Beyond "Witnessing": Children's Experiences of Coercive Control in Domestic Violence and Abuse.

PubMed

Callaghan, Jane E M; Alexander, Joanne H; Sixsmith, Judith; Fellin, Lisa Chiara

2015-12-10

Children's experiences and voices are underrepresented in academic literature and professional practice around domestic violence and abuse. The project "Understanding Agency and Resistance Strategies" (UNARS) addresses this absence, through direct engagement with children. We present an analysis from interviews with 21 children in the United Kingdom (12 girls and 9 boys, aged 8-18 years), about their experiences of domestic violence and abuse, and their responses to this violence. These interviews were analyzed using interpretive interactionism. Three themes from this analysis are presented: (a) "Children's experiences of abusive control," which explores children's awareness of controlling behavior by the adult perpetrator, their experience of that control, and its impact on them; (b) "Constraint," which explores how children experience the constraint associated with coercive control in situations of domestic violence; and (c) "Children as agents," which explores children's strategies for managing controlling behavior in their home and in family relationships. The article argues that, in situations where violence and abuse occur between adult intimate partners, children are significantly affected, and can be reasonably described as victims of abusive control. Recognizing children as direct victims of domestic violence and abuse would produce significant changes in the way professionals respond to them, by (a) recognizing children's experience of the impact of domestic violence and abuse; (b) recognizing children's agency, undermining the perception of them as passive "witnesses" or "collateral damage" in adult abusive encounters; and (c) strengthening professional responses to them as direct victims, not as passive witnesses to violence. © The Author(s) 2015.

Perceptions of entitativity and attitude change.

PubMed

Rydell, Robert J; McConnell, Allen R

2005-01-01

The current work explored the properties of groups that lead them to be persuasive and the processes through which such persuasion occurs. Because more entitative groups induce greater levels of information processing, their arguments should receive greater elaboration, leading to persuasion when members of groups present strong (vs. weak) counter attitudinal arguments. Experiment 1 explored these hypotheses by examining if idiosyncratic perceptions of group entitativity and manipulations of argument strength affect attitude change and argument elaboration. Experiment 2 experimentally manipulated group entitativity and argument strength independently to examine the causal relationship between entitativity, attitude change, and argument elaboration. In both experiments, it was found that groups greater in entitativity were more persuasive when presenting strong (vs. weak) arguments and induced greater argument elaboration. Implications for our understanding of entitativity, persuasion, and information processing about social groups are discussed.

Self-supervised learning as an enabling technology for future space exploration robots: ISS experiments on monocular distance learning

NASA Astrophysics Data System (ADS)

van Hecke, Kevin; de Croon, Guido C. H. E.; Hennes, Daniel; Setterfield, Timothy P.; Saenz-Otero, Alvar; Izzo, Dario

2017-11-01

Although machine learning holds an enormous promise for autonomous space robots, it is currently not employed because of the inherent uncertain outcome of learning processes. In this article we investigate a learning mechanism, Self-Supervised Learning (SSL), which is very reliable and hence an important candidate for real-world deployment even on safety-critical systems such as space robots. To demonstrate this reliability, we introduce a novel SSL setup that allows a stereo vision equipped robot to cope with the failure of one of its cameras. The setup learns to estimate average depth using a monocular image, by using the stereo vision depths from the past as trusted ground truth. We present preliminary results from an experiment on the International Space Station (ISS) performed with the MIT/NASA SPHERES VERTIGO satellite. The presented experiments were performed on October 8th, 2015 on board the ISS. The main goals were (1) data gathering, and (2) navigation based on stereo vision. First the astronaut Kimiya Yui moved the satellite around the Japanese Experiment Module to gather stereo vision data for learning. Subsequently, the satellite freely explored the space in the module based on its (trusted) stereo vision system and a pre-programmed exploration behavior, while simultaneously performing the self-supervised learning of monocular depth estimation on board. The two main goals were successfully achieved, representing the first online learning robotic experiments in space. These results lay the groundwork for a follow-up experiment in which the satellite will use the learned single-camera depth estimation for autonomous exploration in the ISS, and are an advancement towards future space robots that continuously improve their navigation capabilities over time, even in harsh and completely unknown space environments.

A Tracking and Data Relay Satellite System (TDRSS) Onboard Navigation System (TONS) is currently being developed by NASA to provide a high accuracy autonomous navigation capability for users of TDRSS and its successor, the Advanced TDRSS (ATDRSS). The fully autonomous user onboard navigation system will support orbit determination, time determination, and frequency determination, based on observation of a continuously available, unscheduled navigation beacon signal. A TONS experiment will be performed in conjunction with the Explorer Platform (EP) Extreme Ultraviolet Explorer (EUVE) mission to flight quality TONS Block 1. An overview is presented of TONS and a preliminary analysis of the navigation accuracy anticipated for the TONS experiment. Descriptions of the TONS experiment and the associated navigation objectives, as well as a description of the onboard navigation algorithms, are provided. The accuracy of the selected algorithms is evaluated based on the processing of realistic simulated TDRSS one way forward link Doppler measurements. The analysis process is discussed and the associated navigation accuracy results are presented.

Virtual Reality: Bringing the Awe of Our Science into The Classroom with VR

NASA Astrophysics Data System (ADS)

Bell, R. E.; Turrin, M.; Frearson, N.; Boghosian, A.; Ferrini, V. L.; Simpson, F.

2016-12-01

The geosciences are rich in imagery, making them compelling material for immersive teaching experiences. We often work in remote locations, places where few others are able to travel. Flat 2 D images from the field have served explorers and scientists well from the lantern slides brought back from Antarctica to the images scientists and educators now use in powerpoint presentations. These images provide a backdrop to introduce the experience for formal classes and informal presentations. Our stories from the field bring the setting alive for the participants. The travelers presented and the audience passively listened. Immersive learning opportunities are much more powerful than lecturing. We have enlisted both VR and drone imagery to bring learners fully into the experience of science. A 360 VR image brings the viewer into the moment of discovery. Both have been shown to create an active learning setting fully under the learner's control; they explore at their own pace and following their own interest. This learning `sticks', becoming part of the participant's own unique experience in the space. We are building VR images of field experiences and VR data immersion experiences that will transport people into new locations, building a field experience that they can not only see but fully explore. Through VR we introduce new experiences that showcase our science, our careers and our collaborations. Users can spin the view up to see the helicopter landing in a remote field location by the ice. Spin to the right and see a colleague collecting a reading from instruments that have been pulled from the LC130 aircraft. Turn the view to the left and see the harsh windswept environment along the edge of an ice shelf. Look down and note that you feet are encased in snow boots to keep them warm and stable on the ice. The viewer is in the field as part of the science team. Learning in the classroom and through social media is now fully 360 and fully immersive.

A neural framework for organization and flexible utilization of episodic memory in cumulatively learning baby humanoids.

PubMed

Mohan, Vishwanathan; Sandini, Giulio; Morasso, Pietro

2014-12-01

Cumulatively developing robots offer a unique opportunity to reenact the constant interplay between neural mechanisms related to learning, memory, prospection, and abstraction from the perspective of an integrated system that acts, learns, remembers, reasons, and makes mistakes. Situated within such interplay lie some of the computationally elusive and fundamental aspects of cognitive behavior: the ability to recall and flexibly exploit diverse experiences of one's past in the context of the present to realize goals, simulate the future, and keep learning further. This article is an adventurous exploration in this direction using a simple engaging scenario of how the humanoid iCub learns to construct the tallest possible stack given an arbitrary set of objects to play with. The learning takes place cumulatively, with the robot interacting with different objects (some previously experienced, some novel) in an open-ended fashion. Since the solution itself depends on what objects are available in the "now," multiple episodes of past experiences have to be remembered and creatively integrated in the context of the present to be successful. Starting from zero, where the robot knows nothing, we explore the computational basis of organization episodic memory in a cumulatively learning humanoid and address (1) how relevant past experiences can be reconstructed based on the present context, (2) how multiple stored episodic memories compete to survive in the neural space and not be forgotten, (3) how remembered past experiences can be combined with explorative actions to learn something new, and (4) how multiple remembered experiences can be recombined to generate novel behaviors (without exploration). Through the resulting behaviors of the robot as it builds, breaks, learns, and remembers, we emphasize that mechanisms of episodic memory are fundamental design features necessary to enable the survival of autonomous robots in a real world where neither everything can be known nor can everything be experienced.

EXPLORING PATERNAL MATURITY IN THE RELATIONSHIPS BETWEEN OLDER FATHERS AND ADULT CHILDREN

PubMed Central

STELLE, CHARLIE D.; SHEEHAN, NANCY W.

2013-01-01

While research on parent-adult child relationships has expanded over the last two decades, most research has ignored the experiences of older fathers and their relationships with adult children. The present study sought to explore how midlife and older men assess the costs and rewards associated with their fatherhood experiences and how fathers’ level of paternal maturity influences their perceptions of fatherhood. More specifically, the purpose of the present study was two-fold: to explore the costs and rewards of fatherhood and whether paternal maturity serves as a moderator of older men’s fatherhood experiences. A purposive sample of 96 fathers (age 50–80) completed measures assessing ego development, generativity, and costs and rewards of fatherhood. The construct of paternal maturity, hypothesized to influence assessment of fatherhood experiences, was operationally defined as combining both affective (generativity) and cognitive (ego development) levels of psychological maturity. Results indicate mixed support for the influence of paternal maturity on fathers’ perceptions of costs and rewards. Overall, findings note that the affective side of maturity (generativity) is more strongly associated with fathers’ accounts of the costs and rewards than the cognitive side of maturity (ego development). Discussion centers on the utility of these concepts and the implications for continued research into the ongoing relationships between fathers and adult children. PMID:21391406

Telepresence-enabled research and developing work practices

NASA Astrophysics Data System (ADS)

Mirmalek, Z.

2016-02-01

In the fall of 2014, a group of scientists and students conducted two weeks of telepresence-enabled research from the University of Rhode Island Inner Space Center and Woods Hole Oceanographic Institution with the Exploration Vessel Nautilus, which was at sea studying the Kick'em Jenny submarine volcano and Barbados Mud Volcanoes. The way that they conducted their work was not so different from other telepresence-enabled ocean science exploration. As a group, they spanned geographic distance, science expertise, exploration experience, and telepresence-enabled research experience. They were connected through technologies and work culture (e.g., shared habits, values, and practices particular to a community). Uniquely, their project included an NSF-sponsored cultural study on the workgroups' own use of technologies and social processes. The objective of the cultural study was, in part, to identify social and technical features of the work environment that present opportunities to better support science exploration via telepresence. Drawing from this case, and related research, I present some analysis on the developing work culture of telepresence-enabled research and highlight potential adjustments.

Mothers' process of decision making for gastrostomy placement.

PubMed

Brotherton, Ailsa; Abbott, Janice

2012-05-01

In this article we present the findings of an exploration of mothers' discourses on decision making for gastrostomy placement for their child. Exploring in-depth interviews of a purposive sample, we analyzed the mothers' discourses of the decision-making process to understand how their experiences of the process influenced their subsequent constructions of decision making. Mothers negotiated decision making by reflecting on their personal experiences of feeding their child, either orally or via a tube, and interwove their background experiences with the communications from members of the health care team until a decision was reached. Decision making was often fraught with difficulty, resulting in anxiety and guilt. Experiences of decision making ranged from perceived coercion to true choice, which encompasses a truly child-centered decision. The resulting impact of the decision-making process on the mothers was profound. We conclude with an exploration of the implications for clinical practice and describe how health care professionals can support mothers to ensure that decision-making processes for gastrostomy placement in children are significantly improved.

Transportations of space, time and self: the role of reading groups in managing mental distress in the community.

PubMed

Shipman, Judith; McGrath, Laura

2016-10-01

The practice of reading and discussing literature in groups is long established, stretching back into classical antiquity. Although benefits of therapeutic reading groups have been highlighted, research into participants' perceptions of these groups has been limited. To explore the experiences of those attending therapeutic reading groups, considering the role of both the group, and the literature itself, in participants' ongoing experiences of distress. Eleven participants were recruited from two reading groups in the South-East of England. One focus group was run, and eight individuals self-selected for individual interviews. The data were analysed together using a thematic analysis drawing on dialogical theories. Participants described the group as an anchor, which enabled them to use fiction to facilitate the discussion of difficult emotional topics, without referring directly to personal experience. Two aspects of this process are explored in detail: the use of narratives as transportation, helping to mitigate the intensity of distress; and using fiction to explore possibilities, alternative selves and lives. For those who are interested and able, reading groups offer a relatively de-stigmatised route to exploring and mediating experiences of distress. Implications in the present UK funding environment are discussed.

SPIRITUALITY AS A LIVED EXPERIENCE: EXPLORING THE ESSENCE OF SPIRITUALITY FOR WOMEN IN LATE LIFE*

PubMed Central

Manning, Lydia K.

2013-01-01

Against the backdrop of a dramatic increase in the number of individuals living longer, particularly older women, it is vital that researchers explore the intersection of spirituality, gender, and aging. In this qualitative study of six women aged 80 and older, I explore, using, multiple, in-depth interviews, the experiences of spirituality over the life course. A hermeneutic phenomenological analysis of the interviews was performed and provided insights into the nature of their “lived experience” allowing for the understanding of the essence of their spirituality. The results are presented as an interpretation of the participants’ perceptions of their spirituality and spiritual experiences. For the women in this study, the essence of their spirituality lies in: being profoundly grateful; engaging in complete acceptance; and having a strong sense of assuredness, while stressing the linkages and importance of spirituality. Implications for understanding spirituality for older adults are considered. PMID:23185856

Mesoscale weather and climate modeling with the global non-hydrostatic Goddard Earth Observing System Model (GEOS-5) at cloud-permitting resolutions

NASA Astrophysics Data System (ADS)

Putman, W. M.; Suarez, M.

2009-12-01

The Goddard Earth Observing System Model (GEOS-5), an earth system model developed in the NASA Global Modeling and Assimilation Office (GMAO), has integrated the non-hydrostatic finite-volume dynamical core on the cubed-sphere grid. The extension to a non-hydrostatic dynamical framework and the quasi-uniform cubed-sphere geometry permits the efficient exploration of global weather and climate modeling at cloud permitting resolutions of 10- to 4-km on today's high performance computing platforms. We have explored a series of incremental increases in global resolution with GEOS-5 from it's standard 72-level 27-km resolution (~5.5 million cells covering the globe from the surface to 0.1 hPa) down to 3.5-km (~3.6 billion cells). We will present results from a series of forecast experiments exploring the impact of the non-hydrostatic dynamics at transition resolutions of 14- to 7-km, and the influence of increased horizontal/vertical resolution on convection and physical parameterizations within GEOS-5. Regional and mesoscale features of 5- to 10-day weather forecasts will be presented and compared with satellite observations. Our results will highlight the impact of resolution on the structure of cloud features including tropical convection and tropical cyclone predicability, cloud streets, von Karman vortices, and the marine stratocumulus cloud layer. We will also present experiment design and early results from climate impact experiments for global non-hydrostatic models using GEOS-5. Our climate experiments will focus on support for the Year of Tropical Convection (YOTC). We will also discuss a seasonal climate time-slice experiment design for downscaling coarse resolution century scale climate simulations to global non-hydrostatic resolutions of 14- to 7-km with GEOS-5.

Processing of visually presented clock times.

Goolkasian, P; Park, D C

1980-11-01

The encoding and representation of visually presented clock times was investigated in three experiments utilizing a comparative judgment task. Experiment 1 explored the effects of comparing times presented in different formats (clock face, digit, or word), and Experiment 2 examined angular distance effects created by varying positions of the hands on clock faces. In Experiment 3, encoding and processing differences between clock faces and digitally presented times were directly measured. Same/different reactions to digitally presented times were faster than to times presented on a clock face, and this format effect was found to be a result of differences in processing that occurred after encoding. Angular separation also had a limited effect on processing. The findings are interpreted within the framework of theories that refer to the importance of representational codes. The applicability to the data of Bank's semantic-coding theory, Paivio's dual-coding theory, and the levels-of-processing view of memory are discussed.

Advances in perinatal mental health research have provided valuable insights around risk factors for the overall development of maternal distress. However, there is still a limited understanding of the experience of women struggling emotionally during pregnancy. We explored how women view, experience, and interpret psychological distress antenatally. Eighteen Australian women participated in in-depth interviews that were analyzed thematically within a critical realist theoretical framework. We present and situate the current findings within the dominant discourse of the good mother, which arguably promotes guilt and stigma and results in women self-labeling as bad mothers.

AnnotCompute: annotation-based exploration and meta-analysis of genomics experiments

PubMed Central

Zheng, Jie; Stoyanovich, Julia; Manduchi, Elisabetta; Liu, Junmin; Stoeckert, Christian J.

2011-01-01

The ever-increasing scale of biological data sets, particularly those arising in the context of high-throughput technologies, requires the development of rich data exploration tools. In this article, we present AnnotCompute, an information discovery platform for repositories of functional genomics experiments such as ArrayExpress. Our system leverages semantic annotations of functional genomics experiments with controlled vocabulary and ontology terms, such as those from the MGED Ontology, to compute conceptual dissimilarities between pairs of experiments. These dissimilarities are then used to support two types of exploratory analysis—clustering and query-by-example. We show that our proposed dissimilarity measures correspond to a user's intuition about conceptual dissimilarity, and can be used to support effective query-by-example. We also evaluate the quality of clustering based on these measures. While AnnotCompute can support a richer data exploration experience, its effectiveness is limited in some cases, due to the quality of available annotations. Nonetheless, tools such as AnnotCompute may provide an incentive for richer annotations of experiments. Code is available for download at http://www.cbil.upenn.edu/downloads/AnnotCompute.

Freysteinson, Wyona M

2009-01-01

There is no known literature to guide the critical care nurse in the use of mirrors in patient care. This article explores how the author came to believe that mirrors were essential to nursing practice. Misconceptions and assumptions concerning mirrors are explored. A framework that conceptually explores the experience of viewing self in the mirror from the perspective of a person is presented. Five situations in which the mirror may be used in critical care are discussed. This article does not present an authoritative view on mirrors in nursing; rather, it is an invitation to dialogue about a unique element in the environment that may be used to enhance nursing care.

2016-12-01

The ExplorOcean H2O SOS: Help Heal the Ocean—Student Operated Solutions: Operation Climate Change, teaches middle and high school students about ocean threats related to climate change through hands-on activities and learning experiences in the field. During each session (in-class or after-school as a club), students build an understanding about how climate change impacts our oceans using resources provided by ExplorOcean (hands-on activities, presentations, multi-media). Through a student leadership model, students present lessons to each other, interweaving a deep learning of science, 21st century technology, communication skills, and leadership. After participating in learning experiences and activities related to 6 key climate change concepts: 1) Introduction to climate change, 2) Increased sea temperatures, 3) Ocean acidification, 4) Sea level rise, 5) Feedback mechanisms, and 6) Innovative solutions. H2O SOS- Operation Climate change participants select one focus issue and use it to design a multi-pronged campaign to increase awareness about this issue in their local community. The campaign includes social media, an interactive activity, and a visual component. All participating clubs that meet participation and action goals earn a field trip to ExplorOcean where they dive deeper into their selected issue through hands-on activities, real-world investigations, and interviews or presentations with experts. In addition to self-selected opportunities to showcase their focus issue, teams will participate in one of several key events identified by ExplorOcean, including ExplorOcean's annual World Oceans Day Expo.

Exploration of Subglacial Lake Ellsworth

NASA Astrophysics Data System (ADS)

Ross, N.

2012-12-01

Antarctic subglacial lakes are thought to be extreme habitats for microbial life and may contain important records of ice sheet history within their lake-floor sediments. To find if this is true, and to answer the science questions that would follow, direct measurement and sampling of these environments is required. Ever since the water depth of Vostok Subglacial Lake in East Antarctica was shown to be >500 m, attention has been given to how these unique, ancient and pristine subglacial environments may be entered without contamination and adverse disturbance. Several organizations have offered guidelines on the desirable cleanliness and sterility requirements for direct sampling experiments, including the US National Academy of Sciences and the Scientific Committee on Antarctic Research. The aims, design and implementation of subglacial lake access experiments have direct relevance for the exploration of extra-terrestrial ice-covered bodies (e.g. Europa) and the search for microbial life elsewhere in the Solar System. This presentation summarizes the scientific protocols and methods being developed for the exploration of Ellsworth Subglacial Lake in West Antarctica, and provides an up-to-date summary of the status of the project. The proposed exploration, planned for December 2012, involves accessing the lake using a hot-water drill and deploying a sampling probe and sediment corer to allow in situ measurement and sample collection. Details are presented on how this can be undertaken with minimal environmental impact that maximizes scientific return without compromising the environment for future experiments. The implications of this experiment for the search for extra-terrestrial life will be discussed.

Analytical and Experimental Nanomechanical Approaches to Understanding the Ductile-to-Brittle Transition

NASA Astrophysics Data System (ADS)

Hintsala, Eric Daniel

This dissertation presents progress towards understanding the ductile-to-brittle transition (DBT) using a mixture of nanomechanical experiments and an analytical model. The key concept is dislocation shielding of crack tips, which is occurs due to a dislocation back stress. In order to properly evaluate the role of these interactions, in-situ experiments are ideal by reducing the number of interacting dislocations and allowing direct observation of cracking behavior and the dislocations themselves. First, in-situ transmission electron microscope (TEM) compression experiments of plasma-synthesized silicon nanocubes (NCs) are presented which shows plastic strains greater than 50% in a semi-brittle material. The mechanical properties are discussed and plasticity mechanisms are identified using post-mortem imaging with a combination of dark field and high-resolution imaging. This observations help to develop a back stress model which is used to fit the hardening regime. This represents the first study of its kind where back stresses are used in a discrete manner to match hardening rates. However, the important measurable quantities for evaluating the DBT include fracture toughness values and energetic activation parameters for cracking and plasticity. In order to do this, a new method for doing in-situ fracture experiments is explored. This method is pre-notched three point bending experiments, which were fabricated by focused ion beam (FIB) milling. Two different materials are evaluated: a model ductile material, Nitronic 50, an austenitic steel alloy, and a model brittle material, silicon. These experiments are performed in-situ scanning electron microscope (SEM) and TEM and explore different aspects including electron backscatter diffraction (EBSD) to track deformation in SEM scale experiments, pre-notching using a converged TEM beam to produce sharper notches better replicating natural cracks, etching procedures to reduce residual FIB damage and elevated temperature experiments. Lastly, an analytical method to predict DBTs is presented which can account for effects of strain rate, temperature and impurity presence. The model is tested by pre-existing data on macroscopic compact tension specimens of single crystal Fe-3%Si. Next, application of the model to nano/micro scale fracture toughness experiments is explored and the large number of confounding variables is discussed in detail. A first attempt at fitting is also presented.

Exploring "fringe" consciousness: the subjective experience of perceptual fluency and its objective bases.

PubMed

Reber, Rolf; Wurtz, Pascal; Zimmermann, Thomas D

2004-03-01

Perceptual fluency is the subjective experience of ease with which an incoming stimulus is processed. Although perceptual fluency is assessed by speed of processing, it remains unclear how objective speed is related to subjective experiences of fluency. We present evidence that speed at different stages of the perceptual process contributes to perceptual fluency. In an experiment, figure-ground contrast influenced detection of briefly presented words, but not their identification at longer exposure durations. Conversely, font in which the word was written influenced identification, but not detection. Both contrast and font influenced subjective fluency. These findings suggest that speed of processing at different stages condensed into a unified subjective experience of perceptual fluency.

Hodgson, Edward; Papale, William; Nalette, Timothy; Graf, John; Sweterlitsch, Jeffery; Hayley, Elizabeth; Williams, Antony; Button, Amy

2011-01-01

The completion of International Space Station Assembly and transition to a full six person crew has created the opportunity to create and implement flight experiments that will drive down the ultimate risks and cost for human space exploration by maturing exploration technologies in realistic space environments that are impossible or incredibly costly to duplicate in terrestrial laboratories. An early opportunity for such a technology maturation experiment was recognized in the amine swingbed technology baselined for carbon dioxide and humidity control on the Orion spacecraft and Constellation Spacesuit System. An experiment concept using an existing high fidelity laboratory swing bed prototype has been evaluated in a feasibility and concept definition study leading to the conclusion that the envisioned flight experiment can be both feasible and of significant value for NASA s space exploration technology development efforts. Based on the results of that study NASA has proceeded with detailed design and implementation for the flight experiment. The study effort included the evaluation of technology risks, the extent to which ISS provided unique opportunities to understand them, and the implications of the resulting targeted risks for the experiment design and operational parameters. Based on those objectives and characteristics, ISS safety and integration requirements were examined, experiment concepts developed to address them and their feasibility assessed. This paper will describe the analysis effort and conclusions and present the resulting flight experiment concept. The flight experiment, implemented by NASA and launched in two packages in January and August 2011, integrates the swing bed with supporting elements including electrical power and controls, sensors, cooling, heating, fans, air- and water-conserving functionality, and mechanical packaging structure. It is now on board the ISS awaiting installation and activation.

Toxicological Risks During Human Space Exploration

NASA Technical Reports Server (NTRS)

James, John T.; Limero, T. F.; Lam, C. W.; Billica, Roger (Technical Monitor)

2000-01-01

The goal of toxicological risk assessment of human space flight is to identify and quantify significant risks to astronaut health from air pollution inside the vehicle or habitat, and to develop a strategy for control of those risks. The approach to completing a toxicological risk assessment involves data and experience on the frequency and severity of toxicological incidents that have occurred during space flight. Control of these incidents depends on being able to understand their cause from in-flight and ground-based analysis of air samples, crew reports of air quality, and known failures in containment of toxic chemicals. Toxicological risk assessment in exploration missions must be based on an evaluation of the unique toxic hazards presented by the habitat location. For example, lunar and Martian dust must be toxicologically evaluated to determine the appropriate control measures for exploration missions. Experience with near-earth flights has shown that the toxic products from fires present the highest risk to crew health from air pollution. Systems and payload leaks also present a significant hazard. The health risk from toxicity associated with materials offgassing or accumulation of human metabolites is generally well controlled. Early tests of lunar and Martian dust simulants have shown that each posses the potential to cause fibrosis in the lung in a murine model. Toxicological risks from air pollutants in space habitats originate from many sources. A number of risks have been identified through near-earth operations; however, the evaluation of additional new risks present during exploration missions will be a challenge.

Eubanks, E.; Allen, S.; Farmer, S.; Jones, K.

2016-12-01

Being Students of Teacher Researcher Experiences (SoTRE) gives students special advantages that most students do not get. Teachers Elizabeth Eubanks and Steve Allen share their knowledge gained via partnerships with Teacher Researcher Experiences (TRE's) such as the National Oceanographic and Atmospheric Administration Teacher at Sea program (NOAA- TAS), Polar TREC (Teachers and Researchers & Exploring & Collaboration), National Science Foundation (NSF) funded researchers, (EARTH) Education and Research: Testing Hypothesis, the RJ Dunlap Marine Conservation Program, C-DEBI (Center for Dark Energy Biosphere Investigations and (STARS) Sending Teachers Aboard Research Ships, The Maury Project and Mate. Students gain special privileges such as understanding unique research ideas, tracking tagged sharks, following daily journals written on location, taking part in cross-continental experiments, tracking real time data, exploring current research via posters or visiting universities. Furthermore, contacts made by a TRE give students an added set of resources. When doing experiments for class or advancing their education or career goals Eubanks and Allen help students connect with scientists. Many students have felt so strongly about the TRE relationship that they have presented at several local and international science conferences. Their message is to encourage scientists to partner with teachers. The benefits of participation in such conferences have included abstract writing and submission, travel, poster creation, oral presentation, networking and personal research presentation, all tools that they will carry with them for a lifetime.

2015-01-01

Burn injury is a devastating experience affecting all aspects of a person's essence, including his/her identity and perception. These patients require complex cognitive efforts to redefine their identity to deal with difficult condition after burn injury and preserve self-concept. The experience of life after burn injury is generally a solitary one, closely related to the patients' cultural and religious context. Therefore, this study was conducted aiming at investigating burn patients' experiences regarding how to preserve self-concept in life after burn injury in Iran. This qualitative study was carried out using qualitative content analysis and in-depth unstructured interviews with 17 surviving burn subjects. During the qualitative content analysis process, the concept of "locating" as the essence of the participants' experience was extracted as follows: (A) self-exploration (exploring the changes in one's life), (B) others' exploration (exploring the changes in the life of family members and the relationship between self and others), (C) position evaluation (self-position analysis), and (D) self-concept preservation. The present study has developed new understandings of mental experiences of burn patients' self-concept by describing the concept of "self-locating". It helps us in classifying and understanding the concepts described in comprehensive theories developed in this area. They do this by focusing on what burn patients experience for choosing self-preservation strategies and having a meaningful life. The finding can be used as a conceptual framework for palliative care program in Iran.

Background: Burn injury is a devastating experience affecting all aspects of a person's essence, including his/her identity and perception. These patients require complex cognitive efforts to redefine their identity to deal with difficult condition after burn injury and preserve self-concept. The experience of life after burn injury is generally a solitary one, closely related to the patients’ cultural and religious context. Therefore, this study was conducted aiming at investigating burn patients’ experiences regarding how to preserve self-concept in life after burn injury in Iran. Materials and Methods: This qualitative study was carried out using qualitative content analysis and in-depth unstructured interviews with 17 surviving burn subjects. Results: During the qualitative content analysis process, the concept of “locating” as the essence of the participants’ experience was extracted as follows: (A) self-exploration (exploring the changes in one's life), (B) others’ exploration (exploring the changes in the life of family members and the relationship between self and others), (C) position evaluation (self-position analysis), and (D) self-concept preservation. Conclusion: The present study has developed new understandings of mental experiences of burn patients’ self-concept by describing the concept of “self-locating”. It helps us in classifying and understanding the concepts described in comprehensive theories developed in this area. They do this by focusing on what burn patients experience for choosing self-preservation strategies and having a meaningful life.

Homeless persons face many barriers to health care, have few resources, and experience high death rates. They live lives of disenfranchisement and neglect. Few studies have explored their experiences and attitudes toward death and dying. Unfortunately, studies done in other populations may not apply to homeless persons. Exploring these experiences and attitudes may provide insight into life, health care, and end-of-life (EOL) concerns of this population. To explore the experiences and attitudes toward death and dying among homeless persons. Qualitative study utilizing focus groups. Fifty-three homeless persons recruited from homeless service agencies. In-depth interviews, which were audiotaped and transcribed. We present seven themes, some of which are previously unreported. Homeless persons described many significant experiences with death and dying, and many participants suffered losses while very young. These encounters influenced participants' attitudes toward risks and risky behavior: e.g., for some, these experiences provided justification for high-risk behaviors and influenced their behaviors while living on the streets. For others, they may be associated with their homelessness. Finally, these experiences informed their attitudes toward death and dying as well as EOL care; homeless persons believe that care will be poor at the EOL. Findings from this study have implications for addressing social services, health promotion, prevention, and EOL care for homeless persons, as well as for others who are poor and disenfranchised.

Love 2.0: a quantitative exploration of sex and relationships in the virtual world Second Life.

PubMed

Craft, Ashley John

2012-08-01

This study presents the quantitative results of a web-based survey exploring the experiences of those who seek sex and relationships in the virtual world of Second Life. The survey gathered data on demographics, relationships, and sexual behaviors from 235 Second Life residents to compare with U.S. General Social Survey data on Internet users and the general population. The Second Life survey also gathered data on interests in and experiences with a number of sexual practices in both offline and online environments. Comparative analysis found that survey participants were significantly older, more educated, and less religious than a wider group of Internet users, and in certain age groups were far less likely to be married or have children. Motivations for engaging in cybersex were presented. Analysis of interest and experience of different sexual practices supported findings by other researchers that online environments facilitated access, but also indicated that interest in certain sexual practices could differ between offline and online environments.

The paper presents an overview of the scientific space experiments in the Korean Astronaut Program (KAP) that were conducted on the International Space Station (ISS), beginning with launch of the Soyuz TMA-12 spacecraft with the first Korean astronaut and two Russian astronauts on April 8, 2008 and returning to Earth on April 19, 2008. During the 10 days aboard the ISS, the Korean astronaut successfully completed thirteen scientific experiments in biology, life science, material science, earth science, and system engineering, five educational space experiments, and three kinds of international collaboration experiments. These experiments were the first Korean manned space experiments and these missions were the first steps toward the manned space exploration by Korea. In this paper, we briefly discuss the descriptions, conduct, and results of the space experiments and discuss future plans. In addition, the lessons learned with respect to the performing of these manned space experiments on the ISS are presented.

The Spacecraft Fire Experiment (Saffire) - Objectives, Development and Status

NASA Technical Reports Server (NTRS)

Schoren, William; Ruff, Gary A.; Urban, David L.

2016-01-01

Since 2012, the Spacecraft Fire Experiment (Saffire) has been under development by the Spacecraft Fire Safety Demonstration (SFS Demo) project that is funded by NASA's Advanced Exploration Systems Division in the Human Exploration and Operations Mission Directorate. The overall objective of this project is to reduce the uncertainty and risk associated with the design of spacecraft fire safety systems for NASA's exploration missions. This is accomplished by defining, developing, and conducting experiments that address gaps in spacecraft fire safety knowledge and capabilities identified by NASA's Fire Safety System Maturation Team. This paper describes the three Spacecraft Fire Experiments (Saffire-I, -II, and -III) that were developed at NASA-GRC and that will conduct a series of material flammability tests in low-gravity and at length scales that are realistic for a spacecraft fire. The experiments will be conducted in Orbital ATK's Cygnus vehicle after it has unberthed from the International Space Station. The tests will be fully automated with the data downlinked at the conclusion of the test and before the Cygnus vehicle reenters the atmosphere. The objectives of these experiments are to (1) determine how rapidly a large scale fire grows in low-gravity and (2) investigate the low-g flammability limits compared to those obtained in NASA's normal gravity material flammability screening test. The hardware for these experiments has been completed and is awaiting their respective launches, all planned for 2016. This paper will review the objectives of these experiments and how they address several of the knowledge gaps for NASA's exploration missions. The hardware development will be discussed including several novel approaches that were taken for testing and evaluation of these series payloads. The status of the missions and operational status will also be presented.

Legacy, legitimacy, and possibility: an exploration of community health worker experience across the generations in Khayelitsha, South Africa.

PubMed

Swartz, Alison

2013-06-01

In South Africa, the response to HIV and TB epidemics is complex, varied, and contextually defined. "Task-shifting" and a movement toward a decentralized model of care have led to an increased reliance on community health workers (CHWs) providing health care services to residents of impoverished, peri-urban areas. Public health policy tends to present CHWs as a homogeneous group, with little attention paid to the nuances of experience, motivation, and understanding, which distinguish these care workers from one another and from other kinds of health workers. An exploration of the layered meanings of providing community health care services under financially, politically, and socially difficult conditions reveals clear distinctions of experience across the generations. Many older CHWs say that ubuntu, a notion of shared African humanity, is being "killed off" by the younger generation, whereas younger CHWs often describe older women as being "jealous" of the opportunities that this younger generation has for education, training, and employment. The structure of the South African health system, past and present responses to disease epidemics, and the legacy of apartheid's structural violence have amplified these generational differences among CHWs. Using ethnographic data collected from approximately 20 CHWS in a peri-urban settlement in Cape Town, South Africa, I explore how CHWs experience and understand legitimacy in the moral economy of care. A call for closer attention to the experiences of CHWs is critical when designing public health policies for the delivery of health care services in impoverished communities in South Africa. © 2013 by the American Anthropological Association.

Imagery encoding and false recognition errors: Examining the role of imagery process and imagery content on source misattributions.

PubMed

Foley, Mary Ann; Foy, Jeffrey; Schlemmer, Emily; Belser-Ehrlich, Janna

2010-11-01

Imagery encoding effects on source-monitoring errors were explored using the Deese-Roediger-McDermott paradigm in two experiments. While viewing thematically related lists embedded in mixed picture/word presentations, participants were asked to generate images of objects or words (Experiment 1) or to simply name the items (Experiment 2). An encoding task intended to induce spontaneous images served as a control for the explicit imagery instruction conditions (Experiment 1). On the picture/word source-monitoring tests, participants were much more likely to report "seeing" a picture of an item presented as a word than the converse particularly when images were induced spontaneously. However, this picture misattribution error was reversed after generating images of words (Experiment 1) and was eliminated after simply labelling the items (Experiment 2). Thus source misattributions were sensitive to the processes giving rise to imagery experiences (spontaneous vs deliberate), the kinds of images generated (object vs word images), and the ways in which materials were presented (as pictures vs words).

González, Débora; Carvalho, María; Cantillo, Jordi; Aixalá, Marc; Farré, Magí

2017-01-01

The death of a loved one is ultimately a universal experience. However, conventional interventions employed for people suffering with uncomplicated grief have gathered little empirical support. The present study aimed to explore the potential effects of ayahuasca on grief. We compared 30 people who had taken ayahuasca with 30 people who had attended peer-support groups, measuring level of grief and experiential avoidance. We also examined themes in participant responses to an open-ended question regarding their experiences with ayahuasca. The ayahuasca group presented a lower level of grief in the Present Feelings Scale of Texas Revised Inventory of Grief, showing benefits in some psychological and interpersonal dimensions. Qualitative responses described experiences of emotional release, biographical memories, and experiences of contact with the deceased. Additionally, some benefits were identified regarding the ayahuasca experiences. These results provide preliminary data about the potential of ayahuasca as a therapeutic tool in treatments for grief.

Getting into the GROOVE: How Building Effective Education Partnerships and Promoting Authentic Student Research through the Girls' Remotely Operated Ocean Vehicle Exploration (GROOVE) Workshop.

Pelz, M.; Heesemann, M.; Hoeberechts, M.

2017-12-01

This presentation outlines the pilot year of Girls' Remotely Operated Ocean Vehicle Exploration or GROOVE, a hands-on learning program created collaboratively with education partners Ocean Networks Canada and St. Margaret's School (Victoria, BC, Canada). The program features student-led activities, authentic student experiences, clearly outlined learning outcomes, teacher and student self-assessment tools, and curriculum-aligned content. Presented through the lens of STEM, students build a modified Seaperch ROV and explore and research thematic scientific concepts such as buoyancy, electronic circuitry, and deep-sea exploration. Further, students learn engineering skills such as isotropic scaling, soldering, and assembly as they build their ROV. Ocean Networks Canada (ONC), an initiative of the University of Victoria, develops, operates, and maintains cabled ocean observatory systems. These include technologies developed on the world-leading NEPTUNE and VENUS observatories and the ever-expanding network of community observatories in the Arctic and coastal British Columbia. These observatories, large and small, enable communities, users, scientists, teachers, and students to monitor real-time and historical data from the local marine environment from anywhere on the globe. GROOVE, Girls' Remotely Operated Ocean Vehicle Exploration, is ONC's newest educational program and is related to their foundational program K-12 Ocean Sense educational program. This presentation will share our experiences developing, refining, and assessing our efforts to implement GROOVE using a train-the-trainer model aimed at formal and informal K-12 educators. We will highlight lessons learned from multiple perspectives (students, participants, developers, and mentors) with the intent of informing future education and outreach initiatives.

Experience and meaning of user involvement: some explorations from a community mental health project.

PubMed

Truman, Carole; Raine, Pamela

2002-05-01

With an increased interest in and policy commitment to involving service users in the planning and delivery of health service provision, there is a clear need to explore both the rhetoric and realities of what user involvement entails. In the present paper, by drawing upon an evaluation of a community-based exercise facility for people with mental health problems, the authors explore ways in which the reality of user involvement is subject to a range of configurations within health services. The paper describes a piece of qualitative research that was undertaken within a participatory framework to explore the nature of user involvement within the facility. The data have been analysed using a grounded theory approach to provide insights into: the organisational context in which user involvement takes place; factors which encourage meaningful participation on the part of service users; perceived barriers to user involvement; and issues of sustainability and continuity. This research approach has enabled the authors to explore the views and experiences of users, service providers and referral agencies in relation to the nature and potential for user involvement. The findings illustrate ways in which user involvement may take place under both flexible and formal arrangements across a variety of activities. The present paper provides an account of some of the meanings and experiences of what 'successful' user participation may involve and the conditions which underpin 'success'. The authors conclude that successful and meaningful user involvement should enable and support users to recognise their existing skills, and to develop new ones, at a pace that suits their particular circumstances and personal resources. This process may require adaptation not only by organisations, but also by service providers and non-involved users.

Fostering new relational experience: clinical process in couple psychotherapy.

PubMed

Marmarosh, Cheri L

2014-03-01

One of the most critical goals for couple psychotherapy is to foster a new relational experience in the session where the couple feels safe enough to reveal more vulnerable emotions and to explore their defensive withdrawal, aggressive attacking, or blaming. The lived intimate experience in the session offers the couple an opportunity to gain integrative insight into their feelings, expectations, and behaviors that ultimately hinder intimacy. The clinical processes that are necessary include empathizing with the couple and facilitating safety within the session, looking for opportunities to explore emotions, ruptures, and unconscious motivations that maintain distance in the relationship, and creating a new relational experience in the session that has the potential to engender integrative insight. These clinical processes will be presented with empirical support. Experts from a session will be used to highlight how these processes influence the couple and promote increased intimacy.

Two-Year Institution Part-Time Nurse Faculty Experiences During Role Transition and Identity Development: A Phenomenological Study.

PubMed

Owens, Rhoda A

This study explored two-year institution part-time nurse faculty's perceptions of their experiences during their role transitions from nurses in clinical practice to part-time clinical instructors. Part-time nurse faculty enter academia as expert clinicians, but most have little or no training in the pedagogy of effective student learning. A phenomenological study was used to explore the faculty role transition experiences. Findings support the proposition that six participants transitioned from their expert clinician to instructor identities; however, two continue in the process. Critical to this process are relationships with individuals in their environments, past and present experiences, the incentive to learn to be better instructors, and the importance of support and training. A model emerged, Process of Role Transition and Professional Identity Formation for Part-Time Clinical Instructors at Two-Year Institutions, that is potentially useful for administrators in developing individualized orientation and professional development programs.

Using vignettes to explore work-based learning: Part 1.

PubMed

Wareing, Mark

This is the first of two articles exploring the use of vignettes as an alternative method of presenting the data arising from interviews. The interviews were carried out as part of research into work-based learning: both articles are based on findings from a hermeneutic phenomenological study into the lived experience of foundation degree mentors and their students-healthcare assistants undertaking a foundation degree in health and social care in order to become assistant practitioners. Part 1 presents a vignette of a notional workplace mentor (Staff Nurse Sophie) that describes her lived experience supporting two equally notional foundation degree students. Sophie's perspective will be a distillation of data arising from interviews with eight workplace mentors, all employed on acute wards within a large NHS hospital trust. The vignette attempts to demonstrate the role of the workplace mentor in the support of work-based learning, and the interprofessional factors that determine the landscape of workplace learning for foundation degree students. The potential of a vignette to assist in a deeper hermeneutic understanding of meanings arising from data will be explored, and the limitations of the approach considered.

Delusional Ideation, Cognitive Processes and Crime Based Reasoning.

Probabilistic reasoning biases have been widely associated with levels of delusional belief ideation (Galbraith, Manktelow, & Morris, 2010; Lincoln, Ziegler, Mehl, & Rief, 2010; Speechley, Whitman, & Woodward, 2010; White & Mansell, 2009), however, little research has focused on biases occurring during every day reasoning (Galbraith, Manktelow, & Morris, 2011), and moral and crime based reasoning (Wilkinson, Caulfield, & Jones, 2014; Wilkinson, Jones, & Caulfield, 2011). 235 participants were recruited across four experiments exploring crime based reasoning through different modalities and dual processing tasks. Study one explored delusional ideation when completing a visually presented crime based reasoning task. Study two explored the same task in an auditory presentation. Study three utilised a dual task paradigm to explore modality and executive functioning. Study four extended this paradigm to the auditory modality. The results indicated that modality and delusional ideation have a significant effect on individuals reasoning about violent and non-violent crime (p < .05), which could have implication for the presentation of evidence in applied setting such as the courtroom.

Becoming a nurse faculty leader: facing challenges through reflecting, persevering and relating in new ways.

PubMed

Horton-Deutsch, Sara; Young, Patricia K; Nelson, Kristine A

2010-05-01

The aim of the present study was to explore the experience of becoming a nurse faculty leader. In a recent interpretation of 23 interviews conducted with nurse faculty leaders from across the United States about their experiences of becoming a leader three themes were identified: being thrust into leadership, taking risks and facing challenges. This interpretive phenomenological study further explicates three aspects of how nurse educators faced challenges in becoming and serving as a leader. Facing challenges meant reflecting, persevering through difficulties and learning to relate to others in new ways. Exemplars of participant experiences are provided for concreteness, to assist readers in determining how findings resonate with their own experience and how they can actualize this resonance in their own leadership practice. In the present study, reflecting, persevering through difficulties and learning to relate with others in a new way was how leaders faced challenges. Leadership development opportunities that facilitate self-exploration, caring and thoughtful interactions with others and values clarification serve as the foundation for becoming a nurse faculty leader who is, in turn, able to build leadership capacity in other individuals and organizations.

Design preferences and cognitive styles: experimentation by automated website synthesis.

PubMed

Leung, Siu-Wai; Lee, John; Johnson, Chris; Robertson, David

2012-06-29

This article aims to demonstrate computational synthesis of Web-based experiments in undertaking experimentation on relationships among the participants' design preference, rationale, and cognitive test performance. The exemplified experiments were computationally synthesised, including the websites as materials, experiment protocols as methods, and cognitive tests as protocol modules. This work also exemplifies the use of a website synthesiser as an essential instrument enabling the participants to explore different possible designs, which were generated on the fly, before selection of preferred designs. The participants were given interactive tree and table generators so that they could explore some different ways of presenting causality information in tables and trees as the visualisation formats. The participants gave their preference ratings for the available designs, as well as their rationale (criteria) for their design decisions. The participants were also asked to take four cognitive tests, which focus on the aspects of visualisation and analogy-making. The relationships among preference ratings, rationale, and the results of cognitive tests were analysed by conservative non-parametric statistics including Wilcoxon test, Krustal-Wallis test, and Kendall correlation. In the test, 41 of the total 64 participants preferred graphical (tree-form) to tabular presentation. Despite the popular preference for graphical presentation, the given tabular presentation was generally rated to be easier than graphical presentation to interpret, especially by those who were scored lower in the visualization and analogy-making tests. This piece of evidence helps generate a hypothesis that design preferences are related to specific cognitive abilities. Without the use of computational synthesis, the experiment setup and scientific results would be impractical to obtain.

A High-Energy Technology Demonstration Platfom: The First Step in a Stepping Stones Approach to Energy-Rich Space Infrastructures

NASA Technical Reports Server (NTRS)

Carrington, Connie; Day, Greg

2004-01-01

The sun provides an abundant source of energy in space, which can be used to power exploration vehicles and infrastructures that support exploration. A first step in developing and demonstrating the necessary technologies to support solar-powered exploration could be a 100-kWe-class solar-powered platform in Earth orbit. This platform would utilize advanced technologies in solar power collection and generation, power management and distribution, thermal management, and electric propulsion. It would also provide a power-rich free-flying platform to demonstrate in space a portfolio of technology flight experiments. This paper presents a preliminary design concept for a 100-kWe solar-powered satellite with the capability to use high-powered electric propulsion, and to flight-demonstrate a variety of payload experiments.

2013-01-01

While the research literature exploring suicide bereavement has expanded in recent years, this has been primarily quantitative and has focused more on the bereavement experience of parents and siblings. The bereavement experience of young people affected through the suicide death of a friend remains under-conceptualized and not well understood. To develop an understanding of the experiences of young people bereaved by the suicide of a friend. Ten young people participated in a pilot study with in-depth interviews to explore their suicide bereavement experiences. Narrative inquiry methodology was utilized to analyze the qualitative data. The findings indicated multiple grief experiences caused by suicide. Four themes reported are meaning making, feeling guilt, risky coping behavior, and relating to friends following suicide loss. Implications include the need for increased awareness that friends of young people who die by suicide may have significant health and well-being challenges associated with bereavement, and that friends in these circumstances may not readily present at services for assistance.

Educating Through Exploration: Emerging Evidence for Improved Learning Outcomes Using a New Theory of Digital Learning Design

NASA Astrophysics Data System (ADS)

Anbar, Ariel; Center for Education Through eXploration

2018-01-01

Advances in scientific visualization and public access to data have transformed science outreach and communication, but have yet to realize their potential impacts in the realm of education. Computer-based learning is a clear bridge between visualization and education that benefits students through adaptative personalization and enhanced access. Building this bridge requires close partnerships among scientists, technologists, and educators.The Infiniscope project fosters such partnerships to produce exploration-driven online learning experiences that teach basic science concepts using a combination of authentic space science narratives, data, and images, and a personalized guided inquiry approach. Infiniscope includes a web portal to host these digital learning experiences, as well as a teaching network of educators using and modifying these experiences. Infiniscope experiences are built around a new theory of digital learning design that we call “education through exploration” (ETX) developed during the creation of successful online, interactive science courses offered at ASU and other institutions. ETX builds on the research-based practices of active learning and guided inquiry to provide a set of design principles that aim to develop higher order thinking skills in addition to understanding of content. It is employed in these experiences by asking students to solve problems and actively discover relationships, supported by an intelligent tutoring system which provides immediate, personalized feedback and scaffolds scientific thinking and methods. The project is led by ASU’s School of Earth and Space Exploration working with learning designers in the Center for Education Through eXploration, with support from NASA’s Science Mission Directorate as part of the NASA Exploration Connection program.We will present an overview of ETX design, the Infinscope project, and emerging evidence of effectiveness.

Antarctic Exploration Parallels for Future Human Planetary Exploration: Science Operations Lessons Learned, Planning, and Equipment Capabilities for Long Range, Long Duration Traverses

NASA Technical Reports Server (NTRS)

Hoffman, Stephen J.

2012-01-01

The purpose for this workshop can be summed up by the question: Are there relevant analogs to planetary (meaning the Moon and Mars) to be found in polar exploration on Earth? The answer in my opinion is yes or else there would be no reason for this workshop. However, I think some background information would be useful to provide a context for my opinion on this matter. As all of you are probably aware, NASA has been set on a path that, in its current form, will eventually lead to putting human crews on the surface of the Moon and Mars for extended (months to years) in duration. For the past 50 V 60 years, starting not long after the end of World War II, exploration of the Antarctic has accumulated a significant body of experience that is highly analogous to our anticipated activities on the Moon and Mars. This relevant experience base includes: h Long duration (1 year and 2 year) continuous deployments by single crews, h Established a substantial outpost with a single deployment event to support these crews, h Carried out long distance (100 to 1000 kilometer) traverses, with and without intermediate support h Equipment and processes evolved based on lessons learned h International cooperative missions This is not a new or original thought; many people within NASA, including the most recent two NASA Administrators, have commented on the recognizable parallels between exploration in the Antarctic and on the Moon or Mars. But given that level of recognition, relatively little has been done, that I am aware of, to encourage these two exploration communities to collaborate in a significant way. [Slide 4] I will return to NASA s plans and the parallels with Antarctic traverses in a moment, but I want to spend a moment to explain the objective of this workshop and the anticipated products. We have two full days set aside for this workshop. This first day will be taken up with a series of presentations prepared by individuals with experience that extends back as far as the late 1940s and includes contemporary experience. The people presenting bring a variety of points of view, including not only U.S. but international, although most, if not all, have collaborated on international teams. The second day will consist of a series of small focused group interactions centered on those elements likely to be needed for traverse missions, such as mobility, habitation, and extravehicular activity (EVA, aka space suits). Our invited participants will be talking with people that specialize in these elements so that we can foster more direct interaction and exchange of experiences between these two exploration communities. After the workshop we will be preparing a report documenting these presentations and the essence of the focused interactions.

Exploring sustainability transitions in households: insights from real-life experiments

2016-04-01

Societal transformation towards sustainable consumption and production, especially in urban areas, is a key challenge. The design and implementation of sustainable product service systems (PSS) might be the initial point, in which private households play a major role. The Sustainable LivingLab research infrastructure was developed as an experimental setting for investigating consumption and production patterns in private households, especially to explore socio-technical innovations which are helpful to guide sustainability transitions. The suggested presentation describes results of several real-life experiments conducted in German households, e.g. the project SusLabNRW (North-Rhine Westphalia as part of the European SusLabNWE-Project), the EnerTransRuhr project as well as the PATHWAYS project that explore patterns of action, time use, social practices and the related resource use in private households. The presentation gives an overview of the employed methods and analysed data (qualitative interviews, social network analysis, survey on household activities and inventories and a sustainability assessment (resource profiles - MIPS household analysis). Households' resource consumption was calculated in all fields of activity to analyse social practices' impact. The presentation illustrates how aggregated data can inform scenario analysis and concludes with an outlook onto transition pathways at household level and socio-technical innovations in the fields of housing, nutrition and mobility.

This is the second of two articles exploring the use of vignettes as an alternative method of presenting the data arising from interviews. The interviews were carried out as part of research into work-based learning: both articles are based on findings from a hermeneutic phenomenological study into the lived experience of foundation degree mentors and their students-healthcare assistants undertaking a foundation degree in health and social care in order to become assistant practitioners. Part 2 presents a vignette of a notional assistant practitioner, Michelle, that describes her lived experience as a foundation degree student. Michelle's perspective is a distillation of data arising from interviews with 11 former foundation degree students. The vignette attempts to demonstrate the features of 'knowing' and 'becoming' in the practice of foundation degree students, and the impact that being a work-based learner has on students' perceptions of lifelong learning.

Self and time.

Meissner, W W

2008-01-01

This article explores the meaning of subjective time and its implications for the understanding of the nature of the self in psychoanalytic terms. Subjective time, the time experience of intrapsychic life, is distinguished from objective time. Its development and evolution in the course of the life cycle are examined, and various aspects of its phenomenology explored. Implications for the understanding of the structure and functioning of the self, especially the combined influence of physiological and environmental processes reflecting the integration of body-mind in the time experience and self-organization are discussed. Some implications for the engagement of the self in the analytic process are suggested, particularly the focusing of therapeutic interaction in the present moment and the implications of the meaning of structural change in reference to the modification of the self-concept through the revision and integration of memory systems in the present interaction between analyst and analysand.

Service Oriented Robotic Architecture for Space Robotics: Design, Testing, and Lessons Learned

Fluckiger, Lorenzo Jean Marc E; Utz, Hans Heinrich

2013-01-01

This paper presents the lessons learned from six years of experiments with planetary rover prototypes running the Service Oriented Robotic Architecture (SORA) developed by the Intelligent Robotics Group (IRG) at the NASA Ames Research Center. SORA relies on proven software engineering methods and technologies applied to space robotics. Based on a Service Oriented Architecture and robust middleware, SORA encompasses on-board robot control and a full suite of software tools necessary for remotely operated exploration missions. SORA has been eld tested in numerous scenarios of robotic lunar and planetary exploration. The experiments conducted by IRG with SORA exercise a large set of the constraints encountered in space applications: remote robotic assets, ight relevant science instruments, distributed operations, high network latencies and unreliable or intermittent communication links. In this paper, we present the results of these eld tests in regard to the developed architecture, and discuss its bene ts and limitations.

'The bloke can be a bit hazy about what's going on': men and cross-border reproductive treatment.

PubMed

Hudson, Nicky; Culley, Lorraine

2013-09-01

While social science research has begun to demonstrate the significant impact of infertility and involuntary childlessness for men, far fewer studies have specifically explored the male experience of, or men's involvement in, infertility treatment-seeking and there are few published studies which specifically describe men's experiences with cross-border reproduction. This paper presents data from the first UK study of transnational treatment-seeking and specifically explores men's involvement in this process. Data from interviews with 10 men and 34 women who were seeking treatment abroad are organized according to three themes: 'going along with it'; 'being a rock'; and 'doing their bit'. The paper argues that gender is an important aspect of the cross-border treatment experience and that both traditional and emergent gender identities are expressed in the process of treatment-seeking. Healthcare providers need to actively explore men's perspectives of the treatment process in all locations, to improve quality of care by reducing men's feelings of marginalization and enhancing their experience of treatment, especially but not exclusively, around the issue of semen collection.

Use of pragmatism to explore women's experiences of traumatic brain injury: a kaleidoscopic view of the world.

PubMed

O'Reilly, Kate; Peters, Kath; Wilson, Nathan; Kwok, Cannas

2018-03-16

Although more men than women sustain a traumatic brain injury (TBI), approximately one quarter of people with TBIs are women. The experiences of TBI reported in the literature are informed from the masculine perspective and do not adequately represent women's experiences. Pragmatism provides an overarching methodological framework to explore and critique a broader perspective of health, including psychosocial, cultural, spiritual, political and environmental factors, while attempting to address gender inequity. To describe the philosophical background validating the use of pragmatism to research women's experiences of TBI. Given the limited understanding of the interplay of socially constructed barriers with the complex impairments women have following TBI, a novel approach to research is required. Pragmatism offers a way to incorporate critical thinking and advocacy into research designs. The critical feminist transformative framework presented in this paper demonstrates the strengths of using pragmatism as a framework to explore complex phenomena. This paper illustrates how methodology, which is influenced by various philosophical perspectives, can be woven throughout the design of a research project. ©2018 RCN Publishing Company Ltd.

Given the recent success of >GV/m dielectric wakefield accelerator (DWA) breakdown experiments at SLAC, and follow-on coherent Cerenkov radiation production at the UCLA Neptune, a UCLA-USC-SLAC collaboration is now implementing a new set of experiments that explore various DWA scenarios. These experiments are motivated by the opportunities presented by the approval of FACET facility at SLAC, as well as unique pulse-train wakefield drivers at BNL. The SLAC experiments permit further exploration of the multi-GeV/m envelope in DWAs, and will entail investigations of novel materials (e.g. CVD diamond) and geometries (Bragg cylindrical structures, slab-symmetric DWAs), and have an over-riding goal ofmore » demonstrating >GeV acceleration in {approx}33 cm DWA tubes. In the nearer term before FACET's commissioning, we are planning measurements at the BNL ATF, in which we drive {approx}50-200 MV/m fields with single pulses or pulse trains. These experiments are of high relevance to enhancing linear collider DWA designs, as they will demonstrate potential for efficient operation with pulse trains.« less

Undergraduate nursing student mentors' experiences of peer mentoring in Korea: A qualitative analysis.

PubMed

Won, Mi-Ra; Choi, Yun-Jung

2017-04-01

Although mentoring involves the achievement of a mutual relationship between mentors and mentees, most studies have focused on the effects of mentoring on the mentees rather than that on the mentors, which necessitates the need to identify mentors' experiences to provide original resources for mentoring. The purpose of this study was to explore the mentoring experience of nursing students who participated as mentors in a mentoring learning program, to offer evidence-based resources for nursing educators to develop mentoring programs and to use mentorship as an educational method. A qualitative content analysis of transcribed focus groups was conducted to describe and explore the undergraduate nursing students' mentoring experiences. This study was conducted in two nursing schools in South Korea. Fifteen student mentors from the peer mentoring program participated in the present study. They were aged between 21 and 24years, and 87% of the participants were female. The experiences of the mentors were explored through focus groups, and the collected data were analyzed by content analysis. The mentors' experiences could be summarized by the core theme, "Self-growth as a leader," consisting of the following themes: taking pride, guiding mentees, coping with conflicts, and building leadership. The themes and codes derived from mentors' experiences would provide evidence-based guidelines and resources for nursing educators and professionals in related disciplines regarding successful peer mentoring, which could facilitate self-growth and foster the development of leadership skills in undergraduate students.

Seeing ahead: experience and language in spatial perspective.

PubMed

Alloway, Tracy Packiam; Corley, Martin; Ramscar, Michael

2006-03-01

Spatial perspective can be directed by various reference frames, as well as by the direction of motion. In the present study, we explored how ambiguity in spatial tasks can be resolved. Participants were presented with virtual reality environments in order to stimulate a spatialreference frame based on motion. They interacted with an ego-moving spatial system in Experiment 1 and an object-moving spatial system in Experiment 2. While interacting with the virtual environment, the participants were presented with either a question representing a motion system different from that of the virtual environment or a nonspatial question relating to physical features of the virtual environment. They then performed the target task assign the label front in an ambiguous spatial task. The findings indicate that the disambiguation of spatial terms can be influenced by embodied experiences, as represented by the virtual environment, as well as by linguistic context.

The use of a science experiment curriculum with mothers and their preschool children in an Even Start literacy setting: A case study

NASA Astrophysics Data System (ADS)

Cadou, Judith Ann

The purpose of this study was to explore systematically the use of a science experiment curriculum in an Even Start program setting through an in-depth description of the verbal and nonverbal interaction of preschool children and their mothers engaged in constructing knowledge through active science experiment exploration, representative notation, and related informational text experiences. It also sought to document the mothers' perceptions of science exploration as a facilitator for their children's literacy and their awareness of ways to support such growth. Two in-depth studies were presented to profile, in detail, the process of mother and child meaning making within the structure of a science explorations context. An additional eight mother-child dyads participated for purposes of adding breadth to the study. Behaviors were documented through (a) videotape transcriptions of the mother-child interaction in this science inquiry context, (b) observation, (c) field notes, and (d) open-ended interviews with the mothers. Data were analyzed using the constant comparative method. The findings of this naturalistic study suggest the use of a linked mother-child dyad learning and literacy development process using prediction, experimentation, observation, and reflection, combined with related meaning-making verbal interaction, documentation, and reading, facilitated the child's knowledge acquisition, learning interests, and learning methodologies. Specifically, (a) the initiating setup for prediction placed the child at the center of her or his own inquiry and initiated verbal communication; (b) mother and child used the scientific thinking routine of predict, act on objects and observe, discover, evaluate, and make decisions, to be documented in second-level notation, as a mental organizer and scaffolding for inquiry and communication between them; (c) the children showed development in conceptual understanding within the context of active science exploration and across science units; (d) the children used the representative drawing and labeling of the experiment experience for extended experimentation and meaning making, thus using second-level notation for functional purposes; (e) the children showed increased initiative with expository text related to the experiment experiences; and (f) the mothers voiced perception of their children's and their own learning and a sense of efficacy in facilitating their children's learning.

Havelund, Klaus; Johnson, Scott; Rosu, Grigore; Clancy, Daniel (Technical Monitor)

2001-01-01

We briefly present Java PathExplorer (JPAX), a tool developed at NASA Ames for monitoring the execution of Java programs. JPAX can be used not only during program testing to reveal subtle errors, but also can be applied during operation to survey safety critical systems. The tool facilitates automated instrumentation of a program in order to properly observe its execution. The instrumentation can be either at the bytecode level or at the source level when the source code is available. JPaX is an instance of a more general project, called PathExplorer (PAX), which is a basis for experiments rather than a fixed system, capable of monitoring various programming languages and experimenting with other logics and analysis techniques

An Electron-Ion Collider (EIC) has been proposed to further explore the strong force and QCD, focusing on the structure and the interaction of gluon-dominated matter. A generic detector R&D program (EIC PID consortium) for the particle identification in EIC experiments was formed to explore technologically advanced solutions in this scope. In this context two Ring Imaging Cherenkov (RICH) counters have been proposed: a modular RICH detector which consists of an aerogel radiator, a Fresnel lens, a mirrored box, and pixelated photon sensor; a dual-radiator RICH, consisting of an aerogel radiator and C2F6 gas in a mirror-focused configuration. We present the simulations of the two detectors and their estimated performance.

Rapid extraction of gist from visual text and its influence on word recognition.

PubMed

Asano, Michiko; Yokosawa, Kazuhiko

2011-01-01

Two experiments explored rapid extraction of gist from a visual text and its influence on word recognition. In both, a short text (sentence) containing a target word was presented for 200 ms and was followed by a target recognition task. Results showed that participants recognized contextually anomalous word targets less frequently than contextually consistent counterparts (Experiment 1). This context effect was obtained when sentences contained the same semantic content but with disrupted syntactic structure (Experiment 2). Results demonstrate that words in a briefly presented visual sentence are processed in parallel and that rapid extraction of sentence gist relies on a primitive representation of sentence context (termed protocontext) that is semantically activated by the simultaneous presentation of multiple words (i.e., a sentence) before syntactic processing.

The normalization of solar X-ray data from many experiments.

NASA Technical Reports Server (NTRS)

Wende, C. D.

1972-01-01

A conversion factor is used to convert Geiger (GM) tube count rates or ion chamber currents into units of the incident X-ray energy flux in a specified passband. A method is described which varies the passband to optimize these conversion factors such that they are relatively independent of the spectrum of the incident photons. This method was applied to GM tubes flown on Explorers 33 and 35 and Mariner 5 and to ion chambers flown on OSO 3 and OGO 4. Revised conversion factors and passbands are presented, and the resulting absolute solar X-ray fluxes based on these are shown to improve the agreement between the various experiments. Calculations have shown that, although the GM tubes on Explorer 33 viewed the Sun off-axis, the effective passband did not change appreciably, and the simple normalization of the count rates to the count rates of a similar GM tube on Explorer 35 was justified.

Aspects of the linguistic competence of deaf children.

PubMed

Wood, D

1984-02-01

In this paper the following three issues are considered in the light of recent research: Do severely/profoundly deaf children develop a grammar for English? Evidence is presented which suggests that they do and that this grammar displays a number of general characteristics some of which parallel the language of younger hearing children, others that do not. The limitations of this grammar will be discussed and hypotheses about the nature, origins and inevitability of such limitations explored. In what ways do the linguistic experiences of deaf children differ from that of hearing children? Some aspects of the deaf child's experience of language will be explored and their linguistic and psychological implications discussed. The relationships between current research findings on the linguistic development of the deaf and the possibility of improved educational methods will also be explored to consider the various different philosophies currently being debated in this field.

Alexithymia: a further exploration of its nomological network.

Vingerhoets, A J; Van Heck, G L; Grim, R; Bermond, B

1995-01-01

The present studies were designed in order to obtain a better understanding of the nomological network of the alexithymia concept. In study I, the links between alexithymia, coping, and self-rated health were explored. As predicted, strong negative correlations were found between alexithymia and the expression of emotions, daydreams and fantasies, and planful and rational actions. Contrary to expectations, no clear associations were found with self-reported health status. In study II, the focus was on links with personality, temperament, and self-reported (susceptibility to) homesickness. Although some correlations reached statistical significance, all were rather modest. The most remarkable finding was the independence of alexithymia and neuroticism. In study III, the associations between alexithymia and aspects of love experiences were examined, again yielding low correlations. It is concluded that alexithymia is relatively independent of temperament and personality. In addition, it is suggested that the association between alexithymia and the experience of positive emotions deserves further exploration.

Children's experiences of domestic violence and abuse: Siblings' accounts of relational coping.

PubMed

Callaghan, Jane E M; Alexander, Joanne H; Sixsmith, Judith; Fellin, Lisa C

2016-10-01

This article explores how children see their relationships, particularly their sibling relationships, in families affected by domestic violence (DV) and how relationality emerges in their accounts as a resource to build an agentic sense of self. The 'voice' of children is largely absent from the DV literature, which typically portrays them as passive, damaged and relationally incompetent. Children's own understandings of their relational worlds are often overlooked, and consequently, existing models of children's social interactions give inadequate accounts of their meaning-making-in-context. Drawn from a larger study of children's experiences of DV and abuse, this article uses two case studies of sibling relationships to explore young people's use of relational resources, for coping with violence in the home. The article explores how relationality and coping intertwine in young people's accounts and disrupts the taken-for-granted assumption that children's 'premature caring' or 'parentification' is (only) pathological in children's responses to DV. This has implications for understanding young people's experiences in the present and supporting their capacity for relationship building in the future. © The Author(s) 2015.

Experiments in mixed reality

Krum, David M.; Sadek, Ramy; Kohli, Luv; Olson, Logan; Bolas, Mark

2010-01-01

As part of the Institute for Creative Technologies and the School of Cinematic Arts at the University of Southern California, the Mixed Reality lab develops technologies and techniques for presenting realistic immersive training experiences. Such experiences typically place users within a complex ecology of social actors, physical objects, and collections of intents, motivations, relationships, and other psychological constructs. Currently, it remains infeasible to completely synthesize the interactivity and sensory signatures of such ecologies. For this reason, the lab advocates mixed reality methods for training and conducts experiments exploring such methods. Currently, the lab focuses on understanding and exploiting the elasticity of human perception with respect to representational differences between real and virtual environments. This paper presents an overview of three projects: techniques for redirected walking, displays for the representation of virtual humans, and audio processing to increase stress.

GAS-007: First step in a series of Explorer payloads

Kitchens, Philip H.

1987-01-01

As part of the NASA Get Away Special program for flying small, self-contained payloads onboard the Space Shuttle, the Alabama Space and Rocket Center (ASRC) in Huntsville has sponsored three such payloads for its Project Explorer. One of these is GAS-007, which was carried originally on STS mission 41-G in early October 1984. Due to an operational error it was not turned on and was, therefore, subsequently rescheduled and flown on mission 61-C. This paper will review Explorer's history, outline its experiments, present some preliminary experimental results, and describe future ASRC plans for Get Away Special activities, including follow-on Explorers GAS-105 and GAS-608.

Telerobotic Haptic Exploration in Art Galleries and Museums for Individuals with Visual Impairments.

Park, Chung Hyuk; Ryu, Eun-Seok; Howard, Ayanna M

2015-01-01

This paper presents a haptic telepresence system that enables visually impaired users to explore locations with rich visual observation such as art galleries and museums by using a telepresence robot, a RGB-D sensor (color and depth camera), and a haptic interface. The recent improvement on RGB-D sensors has enabled real-time access to 3D spatial information in the form of point clouds. However, the real-time representation of this data in the form of tangible haptic experience has not been challenged enough, especially in the case of telepresence for individuals with visual impairments. Thus, the proposed system addresses the real-time haptic exploration of remote 3D information through video encoding and real-time 3D haptic rendering of the remote real-world environment. This paper investigates two scenarios in haptic telepresence, i.e., mobile navigation and object exploration in a remote environment. Participants with and without visual impairments participated in our experiments based on the two scenarios, and the system performance was validated. In conclusion, the proposed framework provides a new methodology of haptic telepresence for individuals with visual impairments by providing an enhanced interactive experience where they can remotely access public places (art galleries and museums) with the aid of haptic modality and robotic telepresence.

Relative recency influences object-in-context memory

PubMed Central

Tam, Shu K.E.; Bonardi, Charlotte; Robinson, Jasper

2015-01-01

In two experiments rats received training on an object-in-context (OIC) task, in which they received preexposure to object A in context x, followed by exposure to object B in context y. In a subsequent test both A and B are presented in either context x or context y. Usually more exploration is seen of the object that has not previously been paired with the test context, an effect attributed to the ability to remember where an object was encountered. However, in the typical version of this task, object A has also been encountered less recently than object B at test. This is precisely the arrangement in tests of ‘relatively recency’ (RR), in which more remotely presented objects are explored more than objects experienced more recently. RR could contaminate performance on the OIC task, by enhancing the OIC effect when animals are tested in context y, and masking it when the test is in context x. This possibility was examined in two experiments, and evidence for superior performance in context y was obtained. The implications of this for theoretical interpretations of recognition memory and the procedures used to explore it are discussed. PMID:25546721

Strategizing to Make Pornography Worthwhile: A Qualitative Exploration of Women's Agentic Engagement with Sexual Media.

PubMed

Chadwick, Sara B; Raisanen, Jessica C; Goldey, Katherine L; van Anders, Sari

2018-03-01

Women often expect to encounter negative, problematic content when they consume pornography, yet many women use and enjoy pornography anyway. Some research has centered content type (e.g., sexist/violent vs. nonsexist/women-focused) as a key determinant of women's pornography experiences, but this precludes the notion that women are active, engaged consumers of pornography and minimizes women's role in shaping their own experiences. In the present study, we explored how a sample of sexually diverse women in the U.S. (aged 18-64; N = 73) worked toward positive experiences with pornography via active negotiation with negative content, using a secondary analysis of focus group data on women's sexual pleasure. We found that, although women often experienced pornography as risky, many women used it anyway and actively employed strategies to increase the likelihood of having a positive experience. Women's strategies were similar across sexual identity and age groups, but the heteronormative, youth-oriented portrayals of sexuality in mainstream pornography presented unique concerns for heterosexual, queer, and older women. Results have implications for how women can be conceptualized as active, rather than passive, consumers of pornography as well as for how women's agency might influence women's arousal responses to sexually explicit stimuli in research.

Precision muon physics

NASA Astrophysics Data System (ADS)

Gorringe, T. P.; Hertzog, D. W.

2015-09-01

The muon is playing a unique role in sub-atomic physics. Studies of muon decay both determine the overall strength and establish the chiral structure of weak interactions, as well as setting extraordinary limits on charged-lepton-flavor-violating processes. Measurements of the muon's anomalous magnetic moment offer singular sensitivity to the completeness of the standard model and the predictions of many speculative theories. Spectroscopy of muonium and muonic atoms gives unmatched determinations of fundamental quantities including the magnetic moment ratio μμ /μp, lepton mass ratio mμ /me, and proton charge radius rp. Also, muon capture experiments are exploring elusive features of weak interactions involving nucleons and nuclei. We will review the experimental landscape of contemporary high-precision and high-sensitivity experiments with muons. One focus is the novel methods and ingenious techniques that achieve such precision and sensitivity in recent, present, and planned experiments. Another focus is the uncommonly broad and topical range of questions in atomic, nuclear and particle physics that such experiments explore.

Exploration of Friendship Experiences, before and after Illness Onset in Females with Anorexia Nervosa: A Qualitative Study

PubMed Central

Lawrence, Vanessa; Fleming, Caroline; Tchanturia, Kate

2016-01-01

Background Difficulties with social relationships have been implicated in both the development and maintenance of Anorexia Nervosa (AN) but the friendship experiences of individuals with AN have not been explored in depth. Method Ten adults with AN took part in a semi-structured interview about their friendship experiences both before and since the onset of their illness. Results Five principle themes were identified through thematic analysis: Social Concern; Impact of AN; Social Connectedness; Inflexibility and Preferred Social Activity. Difficulties with friendship were present prior to the onset of AN in all cases, with participants experiencing anxiety in relation to various aspects of their friendships. Participants described mixed experiences of how their AN has affected their friendships but most participants described having less contact with their friends since becoming unwell. Conclusion This research highlights the role that social difficulties may play in the development of AN, whilst also emphasising the importance of addressing problems with friendship in the course of inpatient treatment.

Episodic memory for spatial context biases spatial attention.

PubMed

Ciaramelli, Elisa; Lin, Olivia; Moscovitch, Morris

2009-01-01

The study explores the bottom-up attentional consequences of episodic memory retrieval. Individuals studied words (Experiment 1) or pictures (Experiment 2) presented on the left or on the right of the screen. They then viewed studied and new stimuli in the centre of the screen. One-second after the appearance of each stimulus, participants had to respond to a dot presented on the left or on the right of the screen. The dot could follow a stimulus that had been presented, during the study phase, on the same side as the dot (congruent condition), a stimulus that had been presented on the opposite side (incongruent condition), or a new stimulus (neutral condition). Subjects were faster to respond to the dot in the congruent compared to the incongruent condition, with an overall right visual field advantage in Experiment 1. The memory-driven facilitation effect correlated with subjects' re-experiencing of the encoding context (R responses; Experiment 1), but not with their explicit memory for the side of items' presentation (source memory; Experiment 2). The results indicate that memory contents are attended automatically and can bias the deployment of attention. The degree to which memory and attention interact appears related to subjective but not objective indicators of memory strength.

Research knowledge is commonly facilitated at conferences via oral presentations, poster presentations and workshops. Current literature exploring the efficacy of academic posters is however limited. The purpose of this initial study was to explore the perceptions of academic poster presentation, together with its benefits and limitations as an effective mechanism for academic knowledge transfer and contribute to the available academic data. A survey was distributed to 88 delegates who presented academic posters at two Releasing Research and Enterprise Potential conferences in June 2007 and June 2008 at Bournemouth University. This survey addressed attitude and opinion items, together with their general experiences of poster presentations. Descriptive statistics were performed on the responses. A 39% return was achieved with the majority of respondents believing that posters are a good medium for transferring knowledge and a valid form of academic publication. Visual appeal was cited as more influential than subject content, with 94% agreeing that poster imagery is most likely to draw viewer's attention. Respondents also believed that posters must be accompanied by their author in order to effectively communicate the academic content. This pilot study is the first to explore perceptions of the academic poster as a medium for knowledge transfer. Given that academic posters rely heavily on visual appeal and direct author interaction, the medium requires greater flexibility in their design to promote effective knowledge transfer. This paper introduces the concept of the IT-based 'MediaPoster' so as to address the issues raised within published literature and subsequently enhance knowledge-transfer within the field of academic medicine.

Using Interactive 3D PDF for Exploring Complex Biomedical Data: Experiences and Solutions.

PubMed

Newe, Axel; Becker, Linda

2016-01-01

The Portable Document Format (PDF) is the most commonly used file format for the exchange of electronic documents. A lesser-known feature of PDF is the possibility to embed three-dimensional models and to display these models interactively with a qualified reader. This technology is well suited to present, to explore and to communicate complex biomedical data. This applies in particular for data which would suffer from a loss of information if it was reduced to a static two-dimensional projection. In this article, we present applications of 3D PDF for selected scholarly and clinical use cases in the biomedical domain. Furthermore, we present a sophisticated tool for the generation of respective PDF documents.

Free Re-boost Electrodynamic Tether on the International Space Station

NASA Technical Reports Server (NTRS)

Bonometti, Joseph A.; Sorenson, Kirk F.; Jansen, Ralph H.; Dankanich, John W.; Frame, Kyle L.

2005-01-01

The International Space Station (ISS) currently experiences significant orbital drag that requires constant make up propulsion or the Station will quickly reenter the Earth's Atmosphere. The reboost propulsion is presently achieved through the firing of hydrazine rockets at the cost of considerable propellant mass. The problem will inevitably grow much worse as station components continue to be assembled, particularly when the full solar panel arrays are deployed. This paper discusses many long established themes on electrodynamic propulsion in the context of Exploration relevance, shows how to couple unique ISS electrical power system characteristics and suggests a way to tremendously impact ISS's sustainability. Besides allowing launch mass and volume presently reserved for reboost propellant to be reallocated for science experiments and other critically needed supplies, there are a series of technology hardware demonstrations steps that can be accomplished on ISS, which are helpful to NASA s Exploration mission. The suggested ElectroDynamic (ED) tether and flywheel approach is distinctive in its use of free energy currently unusable, yet presently available from the existing solar array panels on ISS. The ideas presented are intended to maximize the utility of Station and radically increase orbital safety.

Despite rapid advances in high-throughput microscopy, quantitative image-based assays still pose significant challenges. While a variety of specialized image analysis tools are available, most traditional image-analysis-based workflows have steep learning curves (for fine tuning of analysis parameters) and result in long turnaround times between imaging and analysis. In particular, cell segmentation, the process of identifying individual cells in an image, is a major bottleneck in this regard. Here we present an alternate, cell-segmentation-free workflow based on PhenoRipper, an open-source software platform designed for the rapid analysis and exploration of microscopy images. The pipeline presented here is optimized for immunofluorescence microscopy images of cell cultures and requires minimal user intervention. Within half an hour, PhenoRipper can analyze data from a typical 96-well experiment and generate image profiles. Users can then visually explore their data, perform quality control on their experiment, ensure response to perturbations and check reproducibility of replicates. This facilitates a rapid feedback cycle between analysis and experiment, which is crucial during assay optimization. This protocol is useful not just as a first pass analysis for quality control, but also may be used as an end-to-end solution, especially for screening. The workflow described here scales to large data sets such as those generated by high-throughput screens, and has been shown to group experimental conditions by phenotype accurately over a wide range of biological systems. The PhenoBrowser interface provides an intuitive framework to explore the phenotypic space and relate image properties to biological annotations. Taken together, the protocol described here will lower the barriers to adopting quantitative analysis of image based screens.

The Experience of Being Obese and the Many Consequences of Stigma

PubMed Central

Ogden, Jane; Clementi, Cecelia

2010-01-01

The present qualitative study aimed to explore how people experience their obesity and to explore the impact of this on their motivations to lose weight. Participants (n = 46) were either currently obese or had been obese and were interviewed about their experiences. Participants described the impact of obesity on aspects of their self-identity and used language such as “ugly”, “freak”, “hate”, “blob”, and “disgust” which reflected the pervasively negative impact of their weight. They highlighted a complex and often contradictory relationship with food and described how such negative experiences were created out of the dynamic between their obesity and a stigmatising social context. Some, however, suggested that such stigma could also have positive consequences by promoting and encouraging behaviour change. Many obese people, therefore, experience their weight in profoundly negative ways as a result of existing within a social context which stigmatises their condition. The results are discussed in terms of the costs and benefits of stigma and a balance between support, tolerance, and collusion in promoting weight loss. PMID:20721360

Exploring students’ adaptive reasoning skills and van Hiele levels of geometric thinking: a case study in geometry

This study aims to explore junior high school students’ adaptive reasoning and the Van Hiele level of geometric thinking. The present study was a quasi-experiment with the non-equivalent control group design. The participants of the study were 34 seventh graders and 35 eighth graders in the experiment classes and 34 seventh graders and 34 eighth graders in the control classes. The students in the experiment classes learned geometry under the circumstances of a Knisley mathematical learning. The data were analyzed quantitatively by using inferential statistics. The results of data analysis show an improvement of adaptive reasoning skills both in the grade seven and grade eight. An improvement was also found for the Van Hiele level of geometric thinking. These results indicate the positive impact of Knisley learning model on students’ adaptive reasoning skills and Van Hiele level of geometric thinking.

All-atom molecular dynamics simulations of biomolecules provide a powerful tool for exploring the structure and dynamics of large protein complexes within realistic cellular environments. Unfortunately, such simulations are extremely demanding in terms of their computational requirements, and they present many challenges in terms of preparation, simulation methodology, and analysis and visualization of results. We describe our early experiences porting the popular molecular dynamics simulation program NAMD and the simulation preparation, analysis, and visualization tool VMD to GPU-accelerated OpenPOWER hardware platforms. We report our experiences with compiler-provided autovectorization and compare with hand-coded vector intrinsics for the POWER8 CPU. We explore the performance benefits obtained from unique POWER8 architectural features such as 8-way SMT and its value for particular molecular modeling tasks. Finally, we evaluate the performance of several GPU-accelerated molecular modeling kernels and relate them to other hardware platforms. PMID:29202130

Mental ill-health, such as depression in the elderly, is a complex issue that is influenced by the life-world perspective of older persons. Their self-management ability should be strengthened based on an understanding of their situation, perspectives, and vulnerability. The aim of this study was to explore and increase understanding of old persons' lived experiences of depression and self-management using an interpretative explorative design. Understanding was developed by means of hermeneutic interpretation. One theme, Relationships and Togetherness, and four subthemes, A Sense of Carrying a Shoulder Bag, Walking on Eggshells, Holding the Reins, and Estrangement--a Loss of Togetherness, emerged. A collaborative approach can be important for empowering older persons through self-development and management. Although the findings of the present study cannot be considered conclusive or definitive, they nevertheless contribute new knowledge of older persons' lived experiences of depression in everyday life.

Exploring hurdles to transfer : student experiences of applying knowledge across disciplines

NASA Astrophysics Data System (ADS)

Lappalainen, Jouni; Rosqvist, Juho

2015-04-01

This paper explores the ways students perceive the transfer of learned knowledge to new situations - often a surprisingly difficult prospect. The novel aspect compared to the traditional transfer studies is that the learning phase is not a part of the experiment itself. The intention was only to activate acquired knowledge relevant to the transfer target using a short primer immediately prior to the situation where the knowledge was to be applied. Eight volunteer students from either mathematics or computer science curricula were given a task of designing an adder circuit using logic gates: a new context in which to apply knowledge of binary arithmetic and Boolean algebra. The results of a phenomenographic classification of the views presented by the students in their post-experiment interviews are reported. The degree to which the students were conscious of the acquired knowledge they employed and how they applied it in a new context emerged as the differentiating factors.

Music to the inner ears: exploring individual differences in musical imagery.

Beaty, Roger E; Burgin, Chris J; Nusbaum, Emily C; Kwapil, Thomas R; Hodges, Donald A; Silvia, Paul J

2013-12-01

In two studies, we explored the frequency and phenomenology of musical imagery. Study 1 used retrospective reports of musical imagery to assess the contribution of individual differences to imagery characteristics. Study 2 used an experience sampling design to assess the phenomenology of musical imagery over the course of one week in a sample of musicians and non-musicians. Both studies found episodes of musical imagery to be common and positive: people rarely wanted such experiences to end and often heard music that was personally meaningful. Several variables predicted musical imagery, including personality, musical preferences, and positive mood. Musicians tended to hear musical imagery more often, but they reported less frequent episodes of deliberately-generated imagery. Taken together, the present research provides new insights into individual differences in musical imagery, and it supports the emerging view that such experiences are common, positive, and more voluntary than previously recognized.

De Garengeot's hernia: our experience of three cases and literature review

PubMed Central

Akbari, Khalid; Wood, Claire; Hammad, Ahmed; Middleton, Simon

2014-01-01

Groin hernia is a common surgical presentation and nearly half of the femoral hernias present acutely with strangulation. The hernia sac usually contains omentum or small bowel. Rarely, the appendix can herniate into the femoral canal. De Garengeot's hernia is the term used to describe the presence of appendicitis in the femoral hernia. Hernia explorations are performed by surgical trainees and encountering a De Garengeot's hernia can be challenging to manage. We report our experience of three cases of this rare entity and a literature review to improve our understanding for optimum management. PMID:25080546

Human factors research as part of a Mars exploration analogue mission on Devon Island

NASA Astrophysics Data System (ADS)

Binsted, Kim; Kobrick, Ryan L.; Griofa, Marc Ó.; Bishop, Sheryl; Lapierre, Judith

2010-06-01

Human factors research is a critical element of space exploration as it provides insight into a crew's performance, psychology and interpersonal relationships. Understanding the way humans work in space-exploration analogue environments permits the development and testing of countermeasures for and responses to potential hazardous situations, and can thus help improve mission efficiency and safety. Analogue missions, such as the one described here, have plausible mission constraints and operational scenarios, similar to those that a real Mars crew would experience. Long duration analogue studies, such as those being conducted at the Flashline Mars Arctic Research Station (FMARS) on Devon Island, Canada, offer an opportunity to study mission operations and human factors in a semi-realistic environment, and contribute to the design of missions to explore the Moon and Mars. The FMARS XI Long Duration Mission (F-XI LDM) was, at four months, the longest designed analogue Mars mission conducted to date, and thus provides a unique insight into human factors issues for long-duration space exploration. Here, we describe the six human factors studies that took place during F-XI LDM, and give a summary of their results, where available. We also present a meta-study, which examined the impact of the human-factors research itself on crew schedule and workload. Based on this experience, we offer some lessons learnt: some aspects (perceived risk and crew motivation, for example) of analogue missions must be realistic for study results to be valid; human factors studies are time-consuming, and should be fully integrated into crew schedules; and crew-ground communication and collaboration under long-term exploration conditions can present serious challenges.

Exploring teachers' perspectives on the impact of out-of-school science-based programs for secondary level physics classrooms in Nebraska

NASA Astrophysics Data System (ADS)

Baquerizo-Birth, Marisol

This exploratory phenomenological study investigates the lived experiences of six high school physics teachers in Nebraska regarding their perceptions on the impact of participating in a science-based out-of-school program. By exploring the research question, we discover how this experience relates to these teachers' self-concept and professional growth. Open-ended, semi-structured, one-on-one interviews are used as the data collection method to explore teachers' perceptions. Responses reveal that teachers participating in the Cosmic Ray Observatory Project (CROP) as a means of exploring advanced, extracurricular physics projects perceive their participation as an opportunity for enrichment, collaboration, helping their students, and empowerment. Intertwined in the presented narratives, teachers refer to their schools' limited administrative support as a source of struggle tied to the challenge of balancing school and teaching responsibilities with CROP participants' responsibilities. This study proposes teachers must feel confident with their specific subject area to achieve a progressive view of self, and that supplemental professional development opportunities are crucial to physics teaching.

Semi-autonomous control schemes can address the limitations of both teleoperation and fully autonomous robotic control of rescue robots in disaster environments by allowing a human operator to cooperate and share such tasks with a rescue robot as navigation, exploration, and victim identification. In this paper, we present a unique hierarchical reinforcement learning-based semi-autonomous control architecture for rescue robots operating in cluttered and unknown urban search and rescue (USAR) environments. The aim of the controller is to enable a rescue robot to continuously learn from its own experiences in an environment in order to improve its overall performance in exploration of unknown disaster scenes. A direction-based exploration technique is integrated in the controller to expand the search area of the robot via the classification of regions and the rubble piles within these regions. Both simulations and physical experiments in USAR-like environments verify the robustness of the proposed HRL-based semi-autonomous controller to unknown cluttered scenes with different sizes and varying types of configurations.

Development of the Hippocampal Cognitive Map in Pre-weanling Rats

Wills, Tom; Cacucci, Francesca; Burgess, Neil; O’Keefe, John

2011-01-01

Orienting in large-scale space depends on the interaction of environmental experience and pre-configured, possibly innate, constructs. Place, head-direction and grid cells in the hippocampal formation provide allocentric representations of space. Here we show how these cognitive representations emerge and develop as rat pups first begin to explore their environment. Directional, locational and rhythmic organization of firing are present during initial exploration, including adult-like directional firing. The stability and precision of place cell firing continues to develop throughout juvenility. Stable grid cell firing appears later but matures rapidly to adult levels. Our results demonstrate the presence of three neuronal representations of space prior to extensive experience, and show how they develop with age. PMID:20558720

In the years of space exploration since the mid-sixties, a wide experience in optical space instrumentation has developed in Germany. This experience ranges from large telescopes in the 1 m and larger category with the accompanying focal plane detectors and spectrometers for all regimes of the electromagnetic spectrum (infrared, visible, ultraviolet, x-rays), to miniature cameras for cometary and planetary explorations. The technologies originally developed for space science. are now also utilized in the fields of earth observation and even optical telecommunication. The presentation will cover all these areas, with examples for specific technological or scientific highlights. Special emphasis will be given to the current state-of-the-art instrumentation technologies in scientific institutions and industry, and to the future perspective in approved and planned projects.

Alcohol and substance dependency are complex, problematic phenomena, which are growing worldwide. In particular, drug use and abuse among young people is a significant concern. Although addiction presents as a problem of dependent individuals, families are also profoundly affected by the family member's addiction. In this narrative literature review, we review published research from 1937 to 2014 to capture a narrative and historical perspective of addiction and family. We condense and analyze the experiences of parents with alcohol- and drug-dependent children, to emphasize the need for a more specific, in-depth exploration of mothers' experiences. Such exploration may advance nurses' understandings of individual, familial, and social complexities of parenting an addicted child. © The Author(s) 2014.

An Electron-Ion Collider (EIC) has been proposed to further explore the strong force and QCD, focusing on the structure and the interaction of gluon-dominated matter. A generic detector R&D program (EIC PID consortium) for the particle identification in EIC experiments was formed to explore technologically advanced solutions in this scope. In this context two Ring Imaging Cherenkov (RICH) counters have been proposed: a modular RICH detector which consists of an aerogel radiator, a Fresnel lens, a mirrored box, and pixelated photon sensor; a dual-radiator RICH, consisting of an aerogel radiator and C 2F 6 gas in a mirror-focused configuration.

[Visual cuing effect for haptic angle judgment].

PubMed

Era, Ataru; Yokosawa, Kazuhiko

2009-08-01

We investigated whether visual cues are useful for judging haptic angles. Participants explored three-dimensional angles with a virtual haptic feedback device. For visual cues, we use a location cue, which synchronizes haptic exploration, and a space cue, which specifies the haptic space. In Experiment 1, angles were judged more correctly with both cues, but were overestimated with a location cue only. In Experiment 2, the visual cues emphasized depth, and overestimation with location cues occurred, but space cues had no influence. The results showed that (a) when both cues are presented, haptic angles are judged more correctly. (b) Location cues facilitate only motion information, and not depth information. (c) Haptic angles are apt to be overestimated when there is both haptic and visual information.

Verification and Validation of Requirements on the CEV Parachute Assembly System Using Design of Experiments

Schulte, Peter Z.; Moore, James W.

2011-01-01

The Crew Exploration Vehicle Parachute Assembly System (CPAS) project conducts computer simulations to verify that flight performance requirements on parachute loads and terminal rate of descent are met. Design of Experiments (DoE) provides a systematic method for variation of simulation input parameters. When implemented and interpreted correctly, a DoE study of parachute simulation tools indicates values and combinations of parameters that may cause requirement limits to be violated. This paper describes one implementation of DoE that is currently being developed by CPAS, explains how DoE results can be interpreted, and presents the results of several preliminary studies. The potential uses of DoE to validate parachute simulation models and verify requirements are also explored.

Walsh, Kathleen M; Blakeney, Barbara A

2013-06-01

The purpose of this study was for nurses to experience equine-assisted learning and for them to describe their being in the moment with their horse. The aims of the study were to assist clinicians in recognizing their ability and skill at being present--that is, calm and centered--as they engage with horses and to determine if interaction with horses is a valid representation in recognizing presence in the participants. Descriptive phenomenology was used to explore this lived experience. Five themes emerged: The Experienced Novice, Present in the Moment, Discovery of Self, Team Building, and Leadership. Equine-assisted learning can be a meaningful venue for nurses to self-discover their ability to be present.

Orion EFT-1 Catalytic Tile Experiment Overview and Flight Measurements

Salazar, Giovanni; Amar, Adam; Hyatt, Andrew; Rezin, Marc D.

2016-01-01

This paper describes the design and results of a surface catalysis flight experiment flown on the Orion Multipurpose Crew Vehicle during Exploration Flight Test 1 (EFT1). Similar to previous Space Shuttle catalytic tile experiments, the present test consisted of a highly catalytic coating applied to an instrumented TPS tile. However, the present catalytic tile experiment contained significantly more instrumentation in order to better resolve the heating overshoot caused by the change in surface catalytic efficiency at the interface between two distinct materials. In addition to collecting data with unprecedented spatial resolution of the "overshoot" phenomenon, the experiment was also designed to prove if such a catalytic overshoot would be seen in turbulent flow in high enthalpy regimes. A detailed discussion of the results obtained during EFT1 is presented, as well as the challenges associated with data interpretation of this experiment. Results of material testing carried out in support of this flight experiment are also shown. Finally, an inverse heat conduction technique is employed to reconstruct the flight environments at locations upstream and along the catalytic coating. The data and analysis presented in this work will greatly contribute to our understanding of the catalytic "overshoot" phenomenon, and have a significant impact on the design of future spacecraft.

2013-03-01

This article explores the experiences and perceptions of Lebanese women and men with economic abuse. Data were drawn from focus group discussions and face-to-face interviews with men, women and social workers. The findings reveal that Lebanese women experience many forms of economic abuse, including the withholding of earnings, restricted involvement in the labor force, and limited purchasing decisions. Inheritance laws and practices still favor men over women. Women tolerate economic abuse to avoid more serious forms of abuse and ensure family stability. Practical implications of the findings are presented.

Kidd, Gary R.; Fogerty, Daniel

2017-01-01

Purpose Three experiments examined the use of competing coordinate response measure (CRM) sentences as a multitalker babble. Method In Experiment I, young adults with normal hearing listened to a CRM target sentence in the presence of 2, 4, or 6 competing CRM sentences with synchronous or asynchronous onsets. In Experiment II, the condition with 6 competing sentences was explored further. Three stimulus conditions (6 talkers saying same sentence, 1 talker producing 6 different sentences, and 6 talkers each saying a different sentence) were evaluated with different methods of presentation. Experiment III examined the performance of older adults with hearing impairment in a subset of conditions from Experiment II. Results In Experiment I, performance declined with increasing numbers of talkers and improved with asynchronous sentence onsets. Experiment II identified conditions under which an increase in the number of talkers led to better performance. In Experiment III, the relative effects of the number of talkers, messages, and onset asynchrony were the same for young and older listeners. Conclusions Multitalker babble composed of CRM sentences has masking properties similar to other types of multitalker babble. However, when the number of different talkers and messages are varied independently, performance is best with more talkers and fewer messages. PMID:28249093

Altered object exploration but not temporal order memory retrieval in an object recognition test following treatment of rats with the group II metabotropic glutamate receptor agonist LY379268.

PubMed

Lins, Brittney R; Ballendine, Stephanie A; Howland, John G

2014-02-07

Temporal order memory refers to the ability to distinguish past experiences in the order that they occurred. Temporal order memory for objects is often tested in rodents using spontaneous object recognition paradigms. The circuitry mediating memory in these tests is distributed and involves ionotropic glutamate receptors in the perirhinal cortex and medial prefrontal cortex. It is unknown what role, if any, metabotropic glutamate receptors have in temporal order memory for objects. The present experiment examined the role of metabotropic glutamate receptors in temporal memory retrieval using the group II metabotropic glutamate receptor selective agonist LY379268. Rats were trained on a temporal memory test with three phases: two sample phases (60 min between them) in which rats explored two novel objects and a test phase (60 min after the second sample phase) which included a copy of each object previously encountered. Under these conditions, we confirmed that rats showed a significant exploratory preference for the object presented during the first sample phase. In a second experiment, we found that LY379268 (0.3, 1.0, or 3.0mg/kg; i.p.; 30 min before the test phase) had no effect on temporal memory retrieval but dose-dependently reduced time spent exploring the objects. Our results show that enhancing mGluR2 activity under conditions when TM is intact does not influence memory retrieval. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Space Weather Status for Exploration Radiation Protection

2011-01-01

Management of crew exposure to radiation is a major concern for manned spaceflight and will be even more important for the modern concept of longer-duration exploration. The inherent protection afforded to astronauts by the magnetic field of the Earth in Low Earth Orbit (LEO) makes operations on the space shuttle or space station very different from operations during an exploration mission. In order to experience significant radiation-derived Loss of Mission (LOM) or Loss of Crew (LOC) risk for LEO operations, one is almost driven to dictate extreme duration or to dictate an extreme sequence of solar activity. Outside of the geo-magnetosphere, however, this scenario changes dramatically. Exposures to the same event on the ISS and in free space, for example, may differ by orders of magnitude. This change in magnitude, coupled with the logistical constraints present in implementing any practical operational mitigation make situational awareness with regard to space weather a limiting factor for the ability to conduct exploration operations. We present a current status of developing operational concepts for manned exploration and expectations for asset viability and available predictive and characterization toolsets.

Moon and Mars gravity environment during parabolic flights: a new European approach to prepare for planetary exploration

NASA Astrophysics Data System (ADS)

Pletser, Vladimir; Clervoy, Jean-Fran; Gharib, Thierry; Gai, Frederic; Mora, Christophe; Rosier, Patrice

Aircraft parabolic flights provide repetitively up to 20 seconds of reduced gravity during ballis-tic flight manoeuvres. Parabolic flights are used to conduct short microgravity investigations in Physical and Life Sciences and in Technology, to test instrumentation prior to space flights and to train astronauts before a space mission. The European Space Agency (ESA) has organized since 1984 more than fifty parabolic flight campaigns for microgravity research experiments utilizing six different airplanes. More than 600 experiments were conducted spanning several fields in Physical Sciences and Life Sciences, namely Fluid Physics, Combustion Physics, Ma-terial Sciences, fundamental Physics and Technology tests, Human Physiology, cell and animal Biology, and technical tests of Life Sciences instrumentation. Since 1997, ESA uses the Airbus A300 'Zero G', the largest airplane in the world used for this type of experimental research flight and managed by the French company Novespace, a subsidiary of the French space agency CNES. From 2010 onwards, ESA and Novespace will offer the possibility of flying Martian and Moon parabolas during which reduced gravity levels equivalent to those on the Moon and Mars will be achieved repetitively for periods of more than 20 seconds. Scientists are invited to submit experiment proposals to be conducted at these partial gravity levels. This paper presents the technical capabilities of the Airbus A300 Zero-G aircraft used by ESA to support and conduct investigations at Moon-, Mars-and micro-gravity levels to prepare research and exploration during space flights and future planetary exploration missions. Some Physiology and Technology experiments performed during past ESA campaigns at 0, 1/6 an 1/3 g are presented to show the interest of this unique research tool for microgravity and partial gravity investigations.

Living with an autonomous spatiotemporal home heating system: Exploration of the user experiences (UX) through a longitudinal technology intervention-based mixed-methods approach.

Rising energy demands place pressure on domestic energy consumption, but savings can be delivered through home automation and engaging users with their heating and energy behaviours. The aim of this paper is to explore user experiences (UX) of living with an automated heating system regarding experiences of control, understanding of the system, emerging thermal behaviours, and interactions with the system as this area is not sufficiently researched in the existing homes setting through extended deployment. We present a longitudinal deployment of a quasi-autonomous spatiotemporal home heating system in three homes. Users were provided with a smartphone control application linked to a self-learning heating algorithm. Rich qualitative and quantitative data presented here enabled a holistic exploration of UX. The paper's contribution focuses on highlighting key aspects of UX living with an automated heating systems including (i) adoption of the control interface into the social context, (ii) how users' vigilance in maintaining preferred conditions prevailed as a better indicator of system over-ride than gross deviation from thermal comfort, (iii) limited but motivated proactivity in system-initiated communications as best strategy for soliciting user feedback when inference fails, and (iv) two main motivations for interacting with the interface - managing irregularities when absent from the house and maintaining immediate comfort, latter compromising of a checking behaviour that can transit to a system state alteration behaviour depending on mismatches. We conclude by highlighting the complex socio-technical context in which thermal decisions are made in a situated action manner, and by calling for a more holistic, UX-focused approach in the design of automated home systems involving user experiences.

We evaluated the extent to which manipulation of early olfactory environment can influence social behaviours in the South American Hystricognath rodent Octodon degus. The early olfactory environment of newborn degus was manipulated by scenting all litter members with eucalyptol during the first month of life. The social behaviour of sexually mature animals (5-7 months old) towards conspecifics was then assessed using a y-maze to compare the response of control (naïve) and treated animals to two different olfactory configurations (experiment 1): (i) a non-familiarized conspecific impregnated with eucalyptol (eucalyptol arm) presented against (ii) a non-familiarized unscented conspecific (control arm). In addition, in dyadic encounters, we assessed the behaviour of control and eucalyptol treated animals towards a non-familiarized conspecific scented with eucalyptol (experiment 2). We found that control subjects explored and spent significantly less time in the eucalyptol arm, indicating neophobic behaviours towards the artificially scented conspecific. Treated subjects explored and spent similar time in both arms of the maze, showing the same interest for both olfactory stimuli presented. During dyadic encounters in experiment 2, an interaction effect between early experience and sex was observed. Control males escaped and avoided their scented partner more frequently than eucalyptol treated male subjects and than females. Both groups did not differ in the exploration of their scented partners, suggesting that avoidance within agonistic context does not relate to neophobic behaviours. Our results suggest that the exposure to eucalyptol during early ontogeny decreases evasive behaviours within an agonistic context as a result of olfactory learning. Altogether, these results indicate that olfactory cues learned in early ontogeny can influence olfactory-guided behaviours in adult degus.

Space Activism as an Epiphanic Belief System

NASA Technical Reports Server (NTRS)

Mendell, Wendell

2006-01-01

Years of interaction with young people in the space industry and in space activists groups led to my observation that many such individuals can cite a quite specific life event that triggered a life-long interest in or commitment to creating a space future. I am particularly intrigued by parallels between such experiences and the phenomenon of epiphanic experiences among committed Christians. I see analogies between the puzzlement among space activists and among Christian groups as to the reasons for so many people being "unbelievers." At a small international meeting on lunar exploration in 2003, I heard two separate lunch speakers cite such personal experiences. At the beginning of a break in that meeting, I grabbed the microphone from the chairman and asked each person to write down on a pad by his chair whether or not he (or she) had experienced a specific event that led to their involvement in space. If the answer was positive, I asked for a brief narrative, for their age at the time, and for their current age. I received 53 submissions, 20% of which simply stated that their involvement in space exploration was happenstance. (Apollo astronaut John Young was among these.) The other 80% of the submissions had specific stories. The ages at the time of the epiphany ranged from 4 to 47; and their current ages ranged from 22 to 78. I will present a high-level characterization of these inputs. Interest in space exploration as a form of belief system is consistent with choosing NASA goals for the purpose of inspiration and with phenomena such as the "Overview Effect". More research might explore what form the transcendent experience takes and whether it might be associated with feelings of universal connection such as the noosphere or "The Force". From a pragmatic point of view, outreach strategies for exploration should focus on giving individuals access to personal, potentially transformational experiences as opposed to astronaut talks at civic clubs.

How children understand idioms in discourse.

PubMed

Cacciari, C; Levorato, M C

1989-06-01

Some studies have shown that children tend to interpret figurative language literally. Our hypothesis is that they can reach an idiomatic competence if idioms are presented within a rich informational environment allowing children to grasp their figurative sense. First and third graders were presented with narratives biased both to the figurative meaning of idioms (experiment 1) and to the literal meaning (experiment 2) and then given a comprehension task. Experiment 3 was designed to investigate children's production of idioms as compared to the comprehension abilities explored in experiments 1 and 2. Results show that informative contexts can improve children's ability to perceive idiomatic meanings even at the age of seven; and that children are less able to produce idioms than to comprehend them. Generally results emphasize that children seem able to perceive that language can be both figurative and literal.

Second language experience facilitates statistical learning of novel linguistic materials

PubMed Central

Potter, Christine E.; Wang, Tianlin; Saffran, Jenny R.

2016-01-01

Recent research has begun to explore individual differences in statistical learning, and how those differences may be related to other cognitive abilities, particularly their effects on language learning. In the present research, we explored a different type of relationship between language learning and statistical learning: the possibility that learning a new language may also influence statistical learning by changing the regularities to which learners are sensitive. We tested two groups of participants, Mandarin Learners and Naïve Controls, at two time points, six months apart. At each time point, participants performed two different statistical learning tasks: an artificial tonal language statistical learning task and a visual statistical learning task. Only the Mandarin-learning group showed significant improvement on the linguistic task, while both groups improved equally on the visual task. These results support the view that there are multiple influences on statistical learning. Domain-relevant experiences may affect the regularities that learners can discover when presented with novel stimuli. PMID:27988939

Haptic discrimination of bilateral symmetry in 2-dimensional and 3-dimensional unfamiliar displays.

PubMed

Ballesteros, S; Manga, D; Reales, J M

1997-01-01

In five experiments, we tested the accuracy and sensitivity of the haptic system in detecting bilateral symmetry of raised-line shapes (Experiments 1 and 2) and unfamiliar 3-D objects (Experiments 3-5) under different time constraints and different modes of exploration. Touch was moderately accurate for detecting this property in raised displays. Experiment 1 showed that asymmetric judgments were systematically more accurate than were symmetric judgements with scanning by one finger. Experiments 2 confirmed the results of Experiment 1 but also showed that bimanual exploration facilitated processing of symmetric shapes without improving asymmetric detections. Bimanual exploration of 3-D objects was very accurate and significantly facilitated processing of symmetric objects under different time constraints (Experiment 3). Unimanual exploration did not differ from bimanual exploration (Experiment 4), but restricting hand movements to one enclosure reduced performance significantly (Experiment 5). Spatial reference information, signal detection measures, and hand movements in processing bilateral symmetry by touch are discussed.

We present MTVis, a multi-touch interactive tree visualization system. The multi-touch interface display hardware is built using the LED-LP technology, and the tree layout is based on RINGS, but enhanced with multitouch interactions. We describe the features of the system, and how the multi-touch interface enhances the user's experience in exploring the tree data structure. In particular, the multi-touch interface allows the user to simultaneously control two child nodes of the root, and rotate them so that some nodes are magnified, while preserving the layout of the tree. We also describe the other meaninful touch screen gestures the users can use to intuitively explore the tree.

Many-body physics using cold atoms

NASA Astrophysics Data System (ADS)

Sundar, Bhuvanesh

Advances in experiments on dilute ultracold atomic gases have given us access to highly tunable quantum systems. In particular, there have been substantial improvements in achieving different kinds of interaction between atoms. As a result, utracold atomic gases oer an ideal platform to simulate many-body phenomena in condensed matter physics, and engineer other novel phenomena that are a result of the exotic interactions produced between atoms. In this dissertation, I present a series of studies that explore the physics of dilute ultracold atomic gases in different settings. In each setting, I explore a different form of the inter-particle interaction. Motivated by experiments which induce artificial spin-orbit coupling for cold fermions, I explore this system in my first project. In this project, I propose a method to perform universal quantum computation using the excitations of interacting spin-orbit coupled fermions, in which effective p-wave interactions lead to the formation of a topological superfluid. Motivated by experiments which explore the physics of exotic interactions between atoms trapped inside optical cavities, I explore this system in a second project. I calculate the phase diagram of lattice bosons trapped in an optical cavity, where the cavity modes mediates effective global range checkerboard interactions between the atoms. I compare this phase diagram with one that was recently measured experimentally. In two other projects, I explore quantum simulation of condensed matter phenomena due to spin-dependent interactions between particles. I propose a method to produce tunable spin-dependent interactions between atoms, using an optical Feshbach resonance. In one project, I use these spin-dependent interactions in an ultracold Bose-Fermi system, and propose a method to produce the Kondo model. I propose an experiment to directly observe the Kondo effect in this system. In another project, I propose using lattice bosons with a large hyperfine spin, which have Feshbach-induced spin-dependent interactions, to produce a quantum dimer model. I propose an experiment to detect the ground state in this system. In a final project, I develop tools to simulate the dynamics of fermionic superfluids in which fermions interact via a short-range interaction.

Contextualising experiences of depression in women from South Asian communities: a discursive approach.

PubMed

Burr, Jennifer; Chapman, Tom

2004-05-01

The aim of this paper is to present an interpretation of the accounts of depression provided by women from South Asian communities. The paper presents the findings from a qualitative study, conducted in the UK, which explored women from South Asian communities and their experiences of depression. It is argued here, through examples of women's accounts of their experiences, that depression is 'embodied', that is, grounded in the materiality of the body which is also immersed in subjective experiences and in the social context of women's lives. Qualitative data were collected from four focus groups and ten individual interviews with women. The analysis involved a discursive approach. Analysis revealed how women made strategic choices in how they presented their symptoms as legitimate and for gaining access to what they perceived to be appropriate healthcare. This is not to argue that this is a culturally specific phenomenon but one which is a feature of all healthcare negotiations.

[Allocation of attentional resource and monitoring processes under rapid serial visual presentation].

PubMed

Nishiura, K

1998-08-01

With the use of rapid serial visual presentation (RSVP), the present study investigated the cause of target intrusion errors and functioning of monitoring processes. Eighteen students participated in Experiment 1, and 24 in Experiment 2. In Experiment 1, different target intrusion errors were found depending on different kinds of letters --romaji, hiragana, and kanji. In Experiment 2, stimulus set size and context information were manipulated in an attempt to explore the cause of post-target intrusion errors. Results showed that as stimulus set size increased, the post-target intrusion errors also increased, but contextual information did not affect the errors. Results concerning mean report probability indicated that increased allocation of attentional resource to response-defining dimension was the cause of the errors. In addition, results concerning confidence rating showed that monitoring of temporal and contextual information was extremely accurate, but it was not so for stimulus information. These results suggest that attentional resource is different from monitoring resource.

Geological and theoretical modeling do indicate that, most probably, a significant part of the volatiles present in the past is presently stocked within the Martian subsurface as ground ice, and as clay minerals (water constitution). The detection of liquid water is of prime interest and should have deep implications in the understanding of the Martian hydrological cycle and also in exobiology. In the frame of the 2005 joint CNES-NASA mission to Mars, a set of 4 NETLANDERs developed by an European consortium is expected to be launched between 2005 and 2007. The geophysical package of each lander will include a geo-radar (GPR experiment), a magnetometer (MAGNET experiment), a seismometer (SEIS experiment) and a meteorological package (ATMIS experiment). The NETLANDER mission offers a unique opportunity to explore simultaneously the subsurface as well as deeper layers of the planetary interior on 4 different landing sites. The complementary contributions of all these geophysical soundings onboard the NETLANDER stations are presented.

The Advanced Integration Matrix (AIM) will design a ground-based test facility for developing revolutionary integrated systems for joint human-robotic missions in order to study and solve systems-level integration issues for exploration missions beyond Low Earth Orbit (LEO). This paper describes development plans for educational outreach activities related to technological and operational integration scenarios similar to the challenges that will be encountered through this project. The education outreach activities will provide hands-on, interactive exercises to allow students of all levels to experience design and operational challenges similar to what NASA deals with everyday in performing the integration of complex missions. These experiences will relate to and impact students everyday lives by demonstrating how their interests in science and engineering can develop into future careers, and reinforcing the concepts of teamwork and conflict resolution. Allowing students to experience and contribute to real-world development, research, and scientific studies of ground-based simulations for complex exploration missions will stimulate interest in the space program, and bring NASA's challenges to the student level. By enhancing existing educational programs and developing innovative activities and presentations, AIM will support NASA s endeavor to "inspire the next generation of explorers.. .as only NASA can."

Wedge absorbers are needed to obtain longitudinal cooling in ionization cooling. They also can be used to obtain emittance exchanges between longitudinal and transverse phase space. There can be large exchanges in emittance, even with single wedges. In the present note we explore the use of wedge absorbers in the MICE experiment to obtain transverse–longitudinal emittance exchanges within present and future operational conditions. The same wedge can be used to explore “direct” and “reverse” emittance exchange dynamics, where direct indicates a configuration that reduces momentum spread and reverse is a configuration that increases momentum spread. Analytical estimated and ICOOL andmore » G4BeamLine simulations of the exchanges at MICE parameters are presented. Large exchanges can be obtained in both reverse and direct configurations.« less

The etemic model of Gypsy Roma Traveller community vulnerability: is it time to rethink our understanding of vulnerability?

PubMed

Heaslip, Vanessa; Hean, Sarah; Parker, Jonathan

2016-08-09

To present a new etemic model of vulnerability. Despite vulnerability being identified as a core consequence of health and health experiences, there has been little research exploring the meaning of vulnerability as a concept. Yet, being vulnerable is known to have dire physical/mental health consequences. It is therefore a fundamental issue for nurses to address. To date, the meaning of the term vulnerability has been influenced by the work of Spiers (Journal of Advanced Nursing, 31, 2000, 715, The Essential Concepts of Nursing: Building Blocks for Practice, 2005, Elsevier, London). Spiers identified two aspects of vulnerability: the etic (external judgment of another persons' vulnerability) and the emic (internal lived experience of vulnerability). This approach has led to a plethora of research which has explored the etic (external judgment) of vulnerability and rendered the internal lived (or emic) experience invisible. Consequences of this, for marginalised communities such as Gypsy Roma Travellers include a lack of culturally sensitive services compounding health inequalities. Position paper. Drawing upon a qualitative phenomenological research study exploring the lived experience of vulnerability from a Gypsy Roma Travelling community (published previously), this paper presents a new model of vulnerability. This etemic model of vulnerability values both external and internal dimensions of vulnerability and argues for a fusion of these two opposing perspectives. If nurses and other health- and social care professionals wish to develop practice that is successful in engaging with Gypsy Roma Travellers, then there is a need to both understand and respect their community. This can be achieved through an etemic approach to understanding their vulnerability achieved by eliciting lived experience alongside the appreciation of epidemiological studies. If nurses and health practitioners used this etemic approach to practice then it would enable both the development and delivery of culturally sensitive services facilitating health access to this community. Only then, will their poor health status be successfully addressed. © 2016 John Wiley & Sons Ltd.

Interprofessional learning in primary care: an exploration of the service user experience leads to a new model for co-learning.

Worswick, Louise; Little, Christine; Ryan, Kath; Carr, Eloise

2015-01-01

Research about service user involvement in research and education focuses on the purpose, the methods, the barriers and the impact of their involvement. Few studies report on the experience of the service users who get involved. This paper reports an exploration of the experience of service users who participated in an interprofessional educational initiative in primary care - the Learning to Improve the Management of Back Pain in the Community (LIMBIC) project. Service users attended workshops with practice teams and assisted them in developing small scale quality improvement projects to improve their provision of care for people with back pain. To explore the experience of service users involved in the LIMBIC project. Using the philosophical and methodological approaches of pragmatism this study analysed data from the wider LIMBIC project and collected primary data through semi structured interviews with service users. Secondary data were reanalysed and integrated with primary data to address the research question. The study was undertaken in the primary health care setting. Patients participated as service users in workshops and quality improvement projects with members from their practice teams. Interviews with service users were transcribed and analysed thematically. Document and thematic analyses of secondary data from the LIMBIC project included focus group transcripts, patient stories, film, emails, meeting notes, a wiki and educational material such as presentations. Themes identified through the analyses illustrated the importance, to the service users, of the sense of community, of clear communication, and of influencing change through involvement. A model for co-learning with service users resulted from the analyses. The experience of service users can be optimised by planning, preparation and support so that their wealth of expertise can be recognised and utilised. A model for co-learning was developed and is presented in this paper. Copyright © 2014 Elsevier Ltd. All rights reserved.

Priming the holiday spirit: persistent activation due to extraexperimental experiences.

PubMed

Coane, Jennifer H; Balota, David A

2009-12-01

The concept of activation is a critical component of many models of cognition. A key characteristic of activation is that recent experience with a concept or stimulus increases the accessibility of the corresponding representation. The extent to which increases in accessibility occur as a result of experiences outside of laboratory settings has not been extensively explored. In the present study, we presented lexical stimuli associated with different holidays and festivities over the course of a year in a lexical decision task. When stimulus meaning and time of testing were congruent (e.g., leprechaun in March), response times were faster and accuracy greater than when meaning and time of test were incongruent (e.g., leprechaun in November). Congruency also benefited performance on a surprise free recall task of the items presented earlier in the lexical decision task. The discussion focuses on potential theoretical accounts of this heightened accessibility of time-of-the-year-relevant concepts.

Mask_explorer: A tool for exploring brain masks in fMRI group analysis.

Gajdoš, Martin; Mikl, Michal; Mareček, Radek

2016-10-01

Functional magnetic resonance imaging (fMRI) studies of the human brain are appearing in increasing numbers, providing interesting information about this complex system. Unique information about healthy and diseased brains is inferred using many types of experiments and analyses. In order to obtain reliable information, it is necessary to conduct consistent experiments with large samples of subjects and to involve statistical methods to confirm or reject any tested hypotheses. Group analysis is performed for all voxels within a group mask, i.e. a common space where all of the involved subjects contribute information. To our knowledge, a user-friendly interface with the ability to visualize subject-specific details in a common analysis space did not yet exist. The purpose of our work is to develop and present such interface. Several pitfalls have to be avoided while preparing fMRI data for group analysis. One such pitfall is spurious non-detection, caused by inferring conclusions in the volume of a group mask that has been corrupted due to a preprocessing failure. We describe a MATLAB toolbox, called the mask_explorer, designed for prevention of this pitfall. The mask_explorer uses a graphical user interface, enables a user-friendly exploration of subject masks and is freely available. It is able to compute subject masks from raw data and create lists of subjects with potentially problematic data. It runs under MATLAB with the widely used SPM toolbox. Moreover, we present several practical examples where the mask_explorer is usefully applied. The mask_explorer is designed to quickly control the quality of the group fMRI analysis volume and to identify specific failures related to preprocessing steps and acquisition. It helps researchers detect subjects with potentially problematic data and consequently enables inspection of the data. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

A LORETA study of mental time travel: similar and distinct electrophysiological correlates of re-experiencing past events and pre-experiencing future events.

PubMed

Lavallee, Christina F; Persinger, Michael A

2010-12-01

Previous studies exploring mental time travel paradigms with functional neuroimaging techniques have uncovered both common and distinct neural correlates of re-experiencing past events or pre-experiencing future events. A gap in the mental time travel literature exists, as paradigms have not explored the affective component of re-experiencing past episodic events; this study explored this sparsely researched area. The present study employed standardized low resolution electromagnetic tomography (sLORETA) to identify electrophysiological correlates of re-experience affect-laden and non-affective past events, as well as pre-experiencing a future anticipated event. Our results confirm previous research and are also novel in that we illustrate common and distinct electrophysiological correlates of re-experiencing affective episodic events. Furthermore, research from this experiment yields results outlining a pattern of activation in the frontal and temporal regions is correlated with the time frame of past or future events subjects imagined.

Re-working biographies: Women's narratives of pregnancy whilst living with epilepsy.

PubMed

Weckesser, Annalise; Denny, Elaine

2017-07-01

This paper explores the multiple ways experiences of pregnancy and early motherhood come to 'rework' the biographies of women living with epilepsy. Pregnancy is explored as a temporarily concurrent status alongside the long-term condition of epilepsy. Narrative interviews were conducted with 32 women from across the UK. Analysis of these narratives suggests that biographical disruption and continuity are both useful in the conceptualisation of women's diverse experiences of pregnancy and epilepsy. Such findings challenge the notion that the presence of a condition over a long period of time leads to the normalisation of illness. Participants' narratives demonstrate that, for some, pregnancy and early motherhood may be disruptive and can raise concerns regarding an ever present condition that may previously have been taken for granted. Findings also indicate the need for a greater consideration of gender and care responsibilities, as well explorations of concomitant conditions, in the theorising of biographies and chronic illness.

What impact do posters have on academic knowledge transfer? A pilot survey on author attitudes and experiences

PubMed Central

2009-01-01

Background Research knowledge is commonly facilitated at conferences via oral presentations, poster presentations and workshops. Current literature exploring the efficacy of academic posters is however limited. The purpose of this initial study was to explore the perceptions of academic poster presentation, together with its benefits and limitations as an effective mechanism for academic knowledge transfer and contribute to the available academic data. Methods A survey was distributed to 88 delegates who presented academic posters at two Releasing Research and Enterprise Potential conferences in June 2007 and June 2008 at Bournemouth University. This survey addressed attitude and opinion items, together with their general experiences of poster presentations. Descriptive statistics were performed on the responses. Results A 39% return was achieved with the majority of respondents believing that posters are a good medium for transferring knowledge and a valid form of academic publication. Visual appeal was cited as more influential than subject content, with 94% agreeing that poster imagery is most likely to draw viewer's attention. Respondents also believed that posters must be accompanied by their author in order to effectively communicate the academic content. Conclusion This pilot study is the first to explore perceptions of the academic poster as a medium for knowledge transfer. Given that academic posters rely heavily on visual appeal and direct author interaction, the medium requires greater flexibility in their design to promote effective knowledge transfer. This paper introduces the concept of the IT-based 'MediaPoster' so as to address the issues raised within published literature and subsequently enhance knowledge-transfer within the field of academic medicine.

McCauley, Claire-Odile; McKenna, Hugh; Keeney, Sinead; McLaughlin, Derek

2017-10-01

The aim of this study was to co-create of an interview schedule exploring mental health recovery in collaboration with young adult service users. Service user involvement in research has been increasingly recognized as providing a vital authentic insight into mental health recovery. Engagement and collaboration with service users have facilitated the exploration of inaccessible or under-investigated aspects of the lived experience of mental health recovery, not only directing the trajectory of research, but making it relevant to their own contextual experience. A qualitative content analysis framework was employed in the co-creation of a semi-structured interview schedule through an engagement process with service users. Two separate engagement groups took place at the premises of the service user organizations, between January - February 2014. Miles and Huberman's analysis framework was chosen for this phase as it enabled the visual presentation of factors, concepts or variables and the established relationship between them. The lived experience of mental ill health in young adulthood and how this was understood by others was a particularly relevant theme for participants. Further themes were identified between the impact of painful experiences at this developmental life stage leading to a deeper understanding of others through finding meaning in their own mental health recovery journey. Our findings identified that suffering painful experiences is an integral aspect in the process of mental health recovery. This understanding has particular relevance to mental health nursing practice, ensuring the care delivered is cognizant of the suffering or painful experiences that young adults are encountering. © 2017 John Wiley & Sons Ltd.

To present a case example of using an arts-based approach and the development of an art exhibit to disseminate research findings from a narrative research study. Once a study has been completed, the final step of dissemination of findings is crucial. In this paper, we explore the benefits of bringing nursing research into public spaces using an arts-based approach. Findings from a qualitative narrative study exploring experiences of living with life-threatening illnesses. Semi-structured in-depth interviews were conducted with 32 participants living with cancer, chronic renal disease, or HIV/AIDS. Participants were invited to share a symbol representing their experience of living with life-threatening illness and the meaning it held for them. The exhibit conveyed experiences of how people story and re-story their lives when living with chronic kidney disease, cancer or HIV. Photographic images of symbolic representations of study participants' experiences and poetic narratives from their stories were exhibited in a public art gallery. The theoretical underpinning of arts-based approaches and the lessons learned in creating an art exhibit from research findings are explored. Creative art forms for research and disseminating knowledge offer new ways of understanding and knowing that are under-used in nursing. Arts-based approaches make visible patients' experiences that are often left unarticulated or hidden. Creative dissemination approaches such as art exhibits can promote insight and new ways of knowing that communicate nursing research to both public and professional audiences.

2010-12-01

To characterize veterinarian-client communication with undisclosed standardized clients (USCs) during discussions regarding euthanasia of a pet. Descriptive study. 32 companion animal veterinarians (16 males and 16 females) in southern Ontario. During 2 clinic visits, 2 cases (a geriatric dog with worsening arthritis and a cat with inappropriate urination) designed to stimulate discussion regarding euthanasia of a pet were presented by different USCs (individuals trained to consistently present a particular case to veterinarians without disclosing their identity). Discussions were audio recorded and analyzed by use of the measure of patient-centered communication (MPCC [a tool to assess and score physician communication behaviors]). Veterinarian and client statements were classified by means of 3 patient-centered components: exploring both the disease and the illness experience, understanding the whole person, and finding common ground. 60 usable recorded discussions were obtained (31 veterinarians; 30 discussions/case). Overall, MPCC scores were significantly lower for the geriatric dog case. For both cases, veterinarians scored highest on finding common ground and lowest on exploring both the disease and the illness experience. Lack of exploration of client feelings, ideas, and expectations and the effect of the illness on the animal's function resulted in low scores among veterinarians. Results indicated that the use of USCs and the MPCC are feasible methods for analysis of veterinarian-client communication during companion animal euthanasia discussions. Findings suggested that some veterinarians do not fully explore client concerns or facilitate client involvement in euthanasia decision making.

Greider geothermal statement, based on testimony presented to Lt. Gov. Dymally Committee. [Development of geothermal industry

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

Greider, B.

Factors that contribute to the delay of geothermal development by utilities are discussed. These include: the increasingly complex regulations on the Geysers field; low quality and sizes of hot water resources; economics of financing geothermal exploration; professional experience; and lack of faith in the technology of conversion of hot water into electricity. Key issues that must be resolved before geothermal development can significantly penetrate the electricity generation industry are presented. It is pointed out that legislation to stimulate development of California's geothermal resources should be based on consideration of the following items: streamlined controls which allow geothermal exploration and developmentmore » to proceed under a minimum of effective regulation; reasonable tax provisions encouraging exploration, research, development, and production of geothermal energy; and suitable economic incentives for utility companies that will encourage early commitment to construct generating plants.

Microstructural Characteristics of Deformed Quartz Under Non-Steady-State Conditions

NASA Astrophysics Data System (ADS)

Soleymani, Hamid; Kidder, Steven B.; Hirth, Greg

2017-12-01

Analysis of rock deformation experiments can be used to better inform studies of the stress history of geologic fault zones. While it is thought that many geological processes are slow enough to reach steady-state, however, the impact of non-steady-state conditions can be significant. For instance it is thought that most rocks experience a gradual increase in stress as they approach the brittle-ductile transition during exhumation, however experiments simulating a gradual stress increase during dislocation creep were not previously carried out. Similarly, while numerical models of earthquakes on major plate boundary fault zones indicate temporarily elevated differential stress and strain-rates below the fault edge in the ductile crust/upper-mantle, few experimental studies have explored the effects of such episodic stress and strain-rates on microstructural evolution. We carried out general-shear and axial compression Griggs rig experiments on Black Hills quartzite (grain size ≈ 100 µm) and synthesized quartz aggregates (grain size ≈ 20 µm) both annealed at 900 °C and confining pressure of 1GPa. The first series of experiments was designed to simulate the stress history of rapidly exhumed rocks. Stress was increased during the experiments by gradually decreasing the temperature from 900 °C to 800 °C at various constant displacement rates. The second series of experiments explores the microstructural and rheological characteristics of quartz deformed to strains of γ ≈ 4 via alternating fast strain rate ( ≈ 1 × 10-3 sec-1 ) and relaxation intervals. Preliminarily mechanical data suggest that our techniques successfully simulate exhumation stress paths and episodic stress pulses. Detailed microstructural analysis of the experimental samples and comparisons to natural samples will be presented to explore the degree to which non-steady-state behavior may be recorded in exhumed rocks.

The nexus of spirituality and outdoor environmental education: Exploring participants' stories from the TorahTrek Guides Track

NASA Astrophysics Data System (ADS)

Wasserman-Singer, Samuel Chaim

There is currently a strong call from outdoor environmental educators to explore the relevance of spirituality in their domain. In this study I use participant observation, as well as other qualitative methods to understand the experiences of participants in the TorahTrek Guides Track, a Jewish wilderness spirituality program. Analysis reveals that antecedent conditions have a large influence on the constructed spiritual meaning of each participant. Themes of community, connectedness, practice, and service are common among all the participants. A dynamic tension is present between time spent on solos and time spent with the group. Participants also report that variations in the physical environment affect their experiences. I consider the implications of these findings for spiritual educators, outdoor environmental educators, and unaffiliated practitioners.

The involvement of "people with experience" in research has developed considerably in the last decade. However, involvement as co-analysts at the point of data analysis and synthesis has received very little attention-in particular, there is very little work that involves people living with dementia as co-analysts. In this qualitative secondary data analysis project, we (a) analyzed data through two theoretical lenses: Douglas's cultural theory of risk and Tronto's Ethic of Care, and (b) analyzed data in workshops with people living with dementia. The design involved cycles of presenting, interpreting, representing and reinterpreting the data, and findings between multiple stakeholders. We explore ways of involving people with experience as co-analysts and explore the role of reflexivity, multiple voicing, literary styling, and performance in participatory data analysis.

Infants use compression information to infer objects’ weights: Examining cognition, exploration, and prospective action in a preferential-reaching task

2012-01-01

The present research used a preferential-reaching task to examine whether 9- and 11-month-olds (n = 144) could infer the relative weights of two objects resting on a soft, compressible platform. Experiment 1 established that infants reached preferentially for the lighter of two boxes. In Experiments 2 to 4, infants saw two boxes identical except in weight resting on a cotton wool platform. Infants reached prospectively for the lighter box, but only when their initial exploratory activities provided critical information. At 11 months, infants succeeded as long as they first determined that the platform was compressible; at 9 months, infants succeeded only if they also explored the boxes and thus had advance knowledge that they differed in weight.

The Quest for Organic Carbon on Mars

NASA Technical Reports Server (NTRS)

Eigenbrode, Jennifer

2011-01-01

We are entering an era of Mars exploration in which organic carbon detection, characterization, and structural identification will be key to addressing some of the outstanding science objectives of the Mars Exploration Program. Success of these missions will depend on technical, scientific, and strategic elements--all of which are strongly determined based on terrestrial experience and knowledge of organic matter formation, concentration, and preservation. Analog studies including Precambrian sediments, modern endolithic communities, and experiments help us fine-tune these approaches, but we also need to expect the unexpected. This presentation will provide perspective on the challenges of detecting organic carbon on Mars, how we may achieve such detections with the in situ instruments, such as the SAM (Science Analysis at Mars) instrument suite onboard Curiosity, the rover for the 2011 Mars Science Laboratory mission.

The experiences of acute non-surgical pain of children who present to a healthcare facility for treatment: a systematic review protocol.

PubMed

Pope, Nicole; Tallon, Mary; McConigley, Ruth; Wilson, Sally

2015-10-01

The qualitative objective of this systematic review is to identify and synthesize the best available evidence on experiences of acute non-surgical pain, including pain management, of children (between four to 18 years) when they present to a healthcare facility for treatment.The specific objectives are to identify: The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage". The pain experience is multifaceted and complex, extending beyond the physiological interpretation of a noxious stimulus, encompassing other dimensions, including; psychological, cognitive, sociocultural, affective and emotional factors. Pain can be described as chronic (persisting for three months or more) or acute (a time limited response to a noxious stimuli). Over the past 50 years clinical research has made revolutionary contributions to better understanding pediatric pain. The once pervasive erroneous notion that infants do not experience pain the same way as adults has been firmly dispelled. We now know that nervous system structures associated with the physiological interpretation of pain are functional as early as fetal development. Despite this critical knowledge and the growing global commitment to improving pediatric pain management in clinical practice, evidence repeatedly suggests that pain management remains suboptimal and inconsistent, a phenomenon commonly referred to as oligoanalgesia. Research evidence has linked poorly managed pain in the pediatric population to negative behavioral and physiological consequences later in life. Effective pain management is therefore a priority area for health care professionals. Improved understanding of children's experiences of acute non-surgical pain may lead to improved pain management and a reduction in oligoanalgesia.In the 1970s and 1980s, studies began exploring the subjective experiences of pediatric pain and discovered children's abilities to articulate their pain experiences, and to link causes and consequences of their pain. Developmental trends or age related patterns with regards to children's expressions and experiences of pain were identified. Recent studies have also recognized apparent trends in children's understanding and expressions of pain; these follow an age and cognitive development trajectory in line with Piaget's theories of development.For many children psychosocial aspects of pain, including emotions like fear, stress and anxiety, are often more unpleasant than the painful experience itself. Emotional responses such as distress and anxiety are commonly associated with the anticipation of pain, can exacerbate and intensify the pain experience, and can significantly lower a child's pain threshold. One study utilized an observational pain assessment tool to explore children's pain experiences. The findings indicated that children who underwent "non-painful" procedures (such as restraint) had equal, and in some cases higher, pain scores than those who underwent painful procedures (such as intravenous cannulation).Several studies exploring pediatric pain within health care settings (including, but not limited to, general practitioners, hospitals, emergency departments and outpatient clinics) have adopted quantitative methods, some examined parents' perspectives, and others explored nurses' perceptions. While results of such studies have added to the existing body of knowledge that supports the need to focus on improving pediatric pain management, it has been suggested that failing to ask children directly risks not capturing subjective experiences of pain from the children's perspectives in their entirety. Seeking the children's perspectives could provide a more reliable and adequate means of gaining insight into their needs and expectations when they are in pain.A single centered study in Singapore used semi-structured face-to-face interviews (n=15) to explore children's experiences of pain management postoperatively. While the children, aged between six and 12 years, identified the role of analgesia in managing their pain, they also placed significant emphasis on the role of parents and health care professionals in implementing non-pharmacological interventions in pain management. These results are relevant as they provide insights into how children experience and express pain, and their expectations of health care professionals in managing their pain. These findings draw attention to effective pain management approaches when caring for children. Similarly, a UK study adopted a cross sectional descriptive design using the draw and write technique aimed at investigating children's views on what helped when they were in pain. The children (n=71) were aged between four and 16 years. Findings revealed that children viewed themselves as active agents in pain management, while also placing significant emphasis on the importance of parents and nurses in managing their pain. In both studies, children valued nurses for social interactions, such as kindness and humor, rather than the provision of clinical care, including analgesia administration. Adjunct therapies such as distraction, visualization and music have also been shown to be effective in managing the pain experience in children.Not only do these findings demonstrate the complexity of the pain experience for the child, they also support the notion that improved pain management may come from research that is designed to better understand the entire pain experience from the child's perspective. While there are systematic reviews on interventions for managing children's pain, and one explored children's experiences in the postoperative context, none have considered children's experiences of acute non-surgical pain when they present for treatment. This qualitative systematic review aims to identify and synthesize results of studies exploring children's experiences of pain and pain management.

The tendency of unconscious thought toward global processing style.

PubMed

Li, Jiansheng; Wang, Fan; Shen, Mowei; Fan, Gang

2017-08-01

This study explored whether unconscious thought has a tendency to process information globally. In three experiments, a Navon task was used to activate global or local processing styles. Findings showed that in the unconscious-thought groups, those performing the local Navon task presented a poorer decision-making performance when compared to those performing the global Navon task (Experiment 1); participants reported that their judgments were made based on partial attributes (Experiment 2), and evaluated a target individual mainly based on information consistent with stereotypes (Experiment 3). These results showed that when presented with distracter tasks, conscious thought activates local processing, which impairs its ability to process information globally. However, this impairment would not happen if global processing were activated instead. This study provides support to the idea that unconscious thought has a tendency to process information globally.

Novacek, Paul F.; Burgess, Malcolm A.; Heck, Michael L.; Stokes, Alan F.; Stough, H. Paul, III (Technical Monitor)

2001-01-01

A two-phase experiment was conducted to explore the effects of data-link weather displays upon pilot decision performance. The experiment was conducted with 49 instrument rated pilots who were divided into four groups and placed in a simulator with a realistic flight scenario involving weather containing convective activity. The inflight weather display depicted NEXRAD images, with graphical and textual METARs over a moving map display. The experiment explored the effect of weather information, ownship position symbology and NEXRAD cell size resolution. The phase-two experiment compared two groups using the data-linked weather display with ownship position symbology. These groups were compared to the phase-one group that did not have ownship position symbology. The phase-two pilots were presented with either large NEXRAD cell size (8 km) or small cell size (4 km). Observations noted that the introduction of ownship symbology did not appear to significantly impact the decision making process, however, the introduction of ownship did reduce workload. Additionally, NEXRAD cell size resolution did appear to influence the tactical decision making process.

2017-01-01

Several instruments based on immunoassay techniques have been proposed for life-detection experiments in the framework of planetary exploration but few experiments have been conducted so far to test the resistance of antibodies against cosmic ray particles. We present several irradiation experiments carried out on both grafted and free antibodies for different types of incident particles (protons, neutrons, electrons and 12C) at different energies (between 9 MeV and 50 MeV) and different fluences. No loss of antibodies activity was detected for the whole set of experiments except when considering protons with energy between 20 and 30 MeV (on free and grafted antibodies) and fluences much greater than expected for a typical planetary mission to Mars for instance. Our results on grafted antibodies suggest that biochip-based instruments must be carefully designed according to the expected radiation environment for a given mission. In particular, a surface density of antibodies much larger than the expected proton fluence would prevent significant loss of antibodies activity and thus assuring a successful detection.

Bridging Differences -- how Social Relationships and Racial Diversity Matter in a Girls' Technology Program

NASA Astrophysics Data System (ADS)

Kekelis, Linda S.; Ancheta, Rebecca Wepsic; Heber, Etta; Countryman, Jeri

In this article, we explore an understudied dimension of girls' single-sex education - how social relationships and racial diversity impact the educational environment for girls, and how teachers may best address these concerns. Findings are presented from a 3-year qualitative study of girls' experiences in a single-sex technology program. Girls valued the all-girls aspect of the programs, and friendships formed the foundation of their social experiences. Girls' friendship groups influenced their experiences and eventually their success in the after school technology programs. When friendship groups were observed to be racially homogeneous, they created challenges for including and supporting a racially diverse student membership. Our responses to the challenges that cultural differences and tensions present are outlined, along with recommendations for helping girls bridge these differences.

Surprising feedback improves later memory.

Fazio, Lisa K; Marsh, Elizabeth J

2009-02-01

The hypercorrection effect is the finding that high-confidence errors are more likely to be corrected after feedback than are low-confidence errors (Butterfield & Metcalfe, 2001). In two experiments, we explored the idea that the hypercorrection effect results from increased attention to surprising feedback. In Experiment 1, participants were more likely to remember the appearance of the presented feedback when the feedback did not match expectations. In Experiment 2, we replicated this effect using more distinctive sources and also demonstrated the hypercorrection effect in this modified paradigm. Overall, participants better remembered both the surface features and the content of surprising feedback.

Generation of oculomotor images during tasks requiring visual recognition of polygons.

PubMed

Olivier, G; de Mendoza, J L

2001-06-01

This paper concerns the contribution of mentally simulated ocular exploration to generation of a visual mental image. In Exp. 1, repeated exploration of the outlines of an irregular decagon allowed an incidental learning of the shape. Analyses showed subjects memorized their ocular movements rather than the polygon. In Exp. 2, exploration of a reversible figure such as a Necker cube varied in opposite directions. Then, both perspective possibilities are presented. The perspective the subjects recognized depended on the way they explored the ambiguous figure. In both experiments, during recognition the subjects recalled a visual mental image of the polygon they compared with the different polygons proposed for recognition. To interpret the data, hypotheses concerning common processes underlying both motor intention of ocular movements and generation of a visual image are suggested.

From sensors for water on the Moon and Mars, to fundamental research on those bodies, and to aids for navigating precisely to landing sites on distant planets, diverse topics were addressed by the Workshop speakers.

Exploring the Therapeutic Affordances of Self-Harm Online Support Communities: An Online Survey of Members

PubMed Central

Bullock, Emma

2017-01-01

Background A growing number of online communities have been established to support those who self-harm. However, little is known about the therapeutic affordances arising from engagement with these communities and resulting outcomes. Objective The aim of this study was to explore the presence of therapeutic affordances as reported by members of self-harm online support communities. Methods In total, 94 respondents (aged 13-63 years, mean=23.5 years; 94% female) completed an online survey exploring their experiences of engaging with a self-harm online support community. Respondents varied in terms of how long they had been accessing an online community, with 22% (21/94) accessing less than 1 year, 39% (37/94) 1 to 2 years, 14% (13/94) 2 to 3 years, and 24.5% (23/94) more than 3 years. Responses were analyzed using deductive thematic analysis. Results The results of our analysis describe each of the five therapeutic affordances that were present in the data, namely (1) connection, the ability to make contact with others who self-harm for the purposes of mutual support and in so doing reduce feelings of loneliness and isolation; (2) adaptation, that is, how use of online support varies in relation to the personal circumstances of the individual user; (3) exploration, that is, the ability to learn about self-harm and learn about strategies to reduce or stop self-harming behavior; (4) narration, that is, the ability to share experiences, as well as read about the experiences of others; and (5) self-presentation, that is, how and what users present about themselves to others in the online community. Conclusions Our findings suggest that engagement with self-harm online support communities may confer a range of therapeutic benefits for some users, which may serve to minimize the psychosocial burden of self-harm and promote positive coping strategies. In addition, the online nature of the support available may be helpful to those who are unable to access face-to-face support. PMID:29030324

Moving the Weber Fraction: The Perceptual Precision for Moment of Inertia Increases with Exploration Force

PubMed Central

Debats, Nienke B.; Kingma, Idsart; Beek, Peter J.; Smeets, Jeroen B. J.

2012-01-01

How does the magnitude of the exploration force influence the precision of haptic perceptual estimates? To address this question, we examined the perceptual precision for moment of inertia (i.e., an object's “angular mass”) under different force conditions, using the Weber fraction to quantify perceptual precision. Participants rotated a rod around a fixed axis and judged its moment of inertia in a two-alternative forced-choice task. We instructed different levels of exploration force, thereby manipulating the magnitude of both the exploration force and the angular acceleration. These are the two signals that are needed by the nervous system to estimate moment of inertia. Importantly, one can assume that the absolute noise on both signals increases with an increase in the signals' magnitudes, while the relative noise (i.e., noise/signal) decreases with an increase in signal magnitude. We examined how the perceptual precision for moment of inertia was affected by this neural noise. In a first experiment we found that a low exploration force caused a higher Weber fraction (22%) than a high exploration force (13%), which suggested that the perceptual precision was constrained by the relative noise. This hypothesis was supported by the result of a second experiment, in which we found that the relationship between exploration force and Weber fraction had a similar shape as the theoretical relationship between signal magnitude and relative noise. The present study thus demonstrated that the amount of force used to explore an object can profoundly influence the precision by which its properties are perceived. PMID:23028437

A Practical, Affordable Cryogenic Propellant Depot Based on ULA's Flight Experience

NASA Technical Reports Server (NTRS)

Kutter, Bernard F.; Zegler, Frank; O'Neil, Gary; Pitchford, Brian

2008-01-01

Mankind is embarking on the next step in the journey of human exploration. We are returning to the moon and eventually moving to Mars and beyond. The current Exploration architecture seeks a balance between the need for a robust infrastructure on the lunar surface, and the performance limitations of Ares I and V. The ability to refuel or top-off propellant tanks from orbital propellant depots offers NASA the opportunity to cost effectively and reliably satisfy these opposing requirements. The ability to cache large orbital quantities of propellant is also an enabling capability for missions to Mars and beyond. This paper describes an option for a propellant depot that enables orbital refueling supporting Exploration, national security, science and other space endeavors. This proposed concept is launched using a single EELV medium class rocket and thus does not require any orbital assembly. The propellant depot provides cryogenic propellant storage that utilizes flight proven technologies augmented with technologies currently under development. The propellant depot system, propellant management, flight experience, and key technologies are also discussed. Options for refueling the propellant depot along with an overview of Exploration architecture impacts are also presented.

Experiments in socially guided exploration: lessons learned in building robots that learn with and without human teachers

NASA Astrophysics Data System (ADS)

Thomaz, Andrea; Breazeal, Cynthia

2008-06-01

We present a learning system, socially guided exploration, in which a social robot learns new tasks through a combination of self-exploration and social interaction. The system's motivational drives, along with social scaffolding from a human partner, bias behaviour to create learning opportunities for a hierarchical reinforcement learning mechanism. The robot is able to learn on its own, but can flexibly take advantage of the guidance of a human teacher. We report the results of an experiment that analyses what the robot learns on its own as compared to being taught by human subjects. We also analyse the video of these interactions to understand human teaching behaviour and the social dynamics of the human-teacher/robot-learner system. With respect to learning performance, human guidance results in a task set that is significantly more focused and efficient at the tasks the human was trying to teach, whereas self-exploration results in a more diverse set. Analysis of human teaching behaviour reveals insights of social coupling between the human teacher and robot learner, different teaching styles, strong consistency in the kinds and frequency of scaffolding acts across teachers and nuances in the communicative intent behind positive and negative feedback.

Termites: a Retinex implementation based on a colony of agents

NASA Astrophysics Data System (ADS)

Simone, Gabriele; Audino, Giuseppe; Farup, Ivar; Rizzi, Alessandro

2012-01-01

This paper describes a novel implementation of the Retinex algorithm with the exploration of the image done by an ant swarm. In this case the purpose of the ant colony is not the optimization of some constraints but is an alternative way to explore the image content as diffused as possible, with the possibility of tuning the exploration parameters to the image content trying to better approach the Human Visual System behavior. For this reason, we used "termites", instead of ants, to underline the idea of the eager exploration of the image. The paper presents the spatial characteristics of locality and discusses differences in path exploration with other Retinex implementations. Furthermore a psychophysical experiment has been carried out on eight images with 20 observers and results indicate that a termite swarm should investigate a particular region of an image to find the local reference white.

Immersive Virtual Reality Field Trips in the Geosciences: Integrating Geodetic Data in Undergraduate Geoscience Courses

High-quality geodetic data and data products, including GPS-GNSS, InSAR, LiDAR, and Structure from Motion (SfM) are opening the doors to visualizing, quantifying, and modeling geologic, tectonic, geomorphic, and geodynamic processes. The integration of these data sets with other geophysical, geochemical and geologic data is providing opportunities for the development of immersive Virtual Reality (iVR) field trips in the geosciences. iVR fieldtrips increase accessibility in the geosciences, by providing experiences that allow for: 1) exploration of field locations that might not be tenable for introductory or majors courses; 2) accessibility to outcrops for students with physical disabilities; and 3) the development of online geosciences courses. We have developed a workflow for producing iVR fieldtrips and tools to make quantitative observations (e.g., distance, area, and volume) within the iVR environment. We use a combination of terrestrial LiDAR and SfM data, 360° photos and videos, and other geophysical, geochemical and geologic data to develop realistic experiences for students to be exposed to the geosciences from sedimentary geology to physical volcanology. We present two of our iVR field trips: 1) Inside the Volcano: Exploring monogenetic volcanism at Thrihnukagigar Iceland; and 2) Changes in Depositional Environment in a Sedimentary Sequence: The Reedsville and Bald Eagle Formations, Pennsylvania. The Thrihnukagigar experience provides the opportunity to investigate monogenetic volcanism through the exploration of the upper 125 m of a fissure-cinder cone eruptive system. Students start at the plate boundary scale, then zoom into a single volcano where they can view the 3D geometry from either terrestrial LiDAR or SfM point clouds, view geochemical data and petrologic thins sections of rock samples, and a presentation of data collection and analysis, results and interpretation. Our sedimentary geology experience is based on a field lab from our introductory Physical Geology course for majors in Geoscience and Engineering. The lab explores formation of a turbidite sequence, and the transition to a shallower marine environment using the tools described above and data from SfM and 360° photos. We are evaluating the effectiveness of both iVR field trips on student learning.

Thorough exploration of complex environments with a space-based potential field

Robotic exploration, for the purposes of search and rescue or explosive device detection, can be improved by using a team of multiple robots. Potential field navigation methods offer natural and efficient distributed exploration algorithms in which team members are mutually repelled to spread out and cover the area efficiently. However, they also suffer from field minima issues. Liu and Lyons proposed a Space-Based Potential Field (SBPF) algorithm that disperses robots efficiently and also ensures they are driven in a distributed fashion to cover complex geometry. In this paper, the approach is modified to handle two problems with the original SBPF method: fast exploration of enclosed spaces, and fast navigation of convex obstacles. Firstly, a "gate-sensing" function was implemented. The function draws the robot to narrow openings, such as doors or corridors that it might otherwise pass by, to ensure every room can be explored. Secondly, an improved obstacle field conveyor belt function was developed which allows the robot to avoid walls and barriers while using their surface as a motion guide to avoid being trapped. Simulation results, where the modified SPBF program controls the MobileSim Pioneer 3-AT simulator program, are presented for a selection of maps that capture difficult to explore geometries. Physical robot results are also presented, where a team of Pioneer 3-AT robots is controlled by the modified SBPF program. Data collected prior to the improvements, new simulation results, and robot experiments are presented as evidence of performance improvements.

A Cognitive Assessment of Highly Superior Autobiographical Memory

Highly Superior Autobiographical Memory (HSAM) is characterized as the ability to accurately recall an exceptional number of experiences and their associated dates from events occurring throughout much of one’s lifetime. The source of this ability has only begun to be explored. The present study explores whether other enhanced cognitive processes may be critical influences underlying HSAM abilities. We investigated whether enhanced abilities in the domains of verbal fluency, attention/inhibition, executive functioning, mnemonic discrimination, perception, visual working memory, or the processing of and memory for emotional details might contribute critically to HSAM. The results suggest that superior cognitive functioning is an unlikely basis of HSAM, as only modest advantages were found in only a few tests. In addition, we examined HSAM subjects’ memory of the testing episodes. Interestingly, HSAM participants recalled details of their own experiences far better than those experiences that the experimenter shared with them. These findings provide additional evidence that HSAM involves, relatively selectively, recollection of personal, autobiographical material. PMID:26982996

Symptom and Surface: Disruptive Deafness and Medieval Medical Authority.

PubMed

Hsy, Jonathan

2016-12-01

This essay examines constructions of deafness in medieval culture, exploring how deaf experience disrupts authoritative discourses in three textual genres: medical treatise, literary fiction, and autobiographical writing. Medical manuals often present deafness as a physical defect, yet they also suggest how social conditions for deaf people can be transformed in lieu of treatment protocols. Fictional narratives tend to associate deafness with sin or social stigma, but they can also imagine deaf experience with a remarkable degree of sympathy and nuance. Autobiographical writing by deaf authors most vividly challenges diagnostic models of disability, exploring generative forms of perception that deafness can foster. In tracing the disruptive force that deaf experience exerts on perceived notions of textual authority, this essay reveals how medieval culture critiqued the diagnostic power of medical practitioners. Deafness does not simply function as a symptom of an individual problem or a metaphor for a spiritual or social condition; rather, deafness is a transformative capacity affording new modes of knowing self and other.

Picture This: Exploring the Lived Experience of High-Functioning Stroke Survivors Using Photovoice.

An increasing number of high-functioning stroke survivors are present with minimal functional impairments and are often discharged with reduced access to community reintegration. Our objectives were to explore the lived experience of high-functioning stroke survivors and to identify gaps in community and rehabilitation services. Photovoice was used with five high-functioning stroke survivors to photo-document their experiences. A modified inductive thematic analysis was used, and meanings behind the photographs were elicited through four focus group sessions followed by photography exhibitions. Five themes emerged: lack of understanding and consideration for persons with disability, emotional and behavioral impacts after stroke, self-reliance and dependence on others, importance of appropriate and accessible services, and financial determinants of quality of life. By including service users' voices; investing in adapted, community-based programs; and providing educational programs for creating attitudinal change among service providers, the polarization between who can and cannot access services will be reduced. © The Author(s) 2016.

Experience of suicidal thoughts: a discourse analytic study.

PubMed

Galasiński, Dariusz; Ziółkowska, Justyna

2013-01-01

In this paper we explore the relationship between current psychiatric thinking on suicide and service users' accounts of suicidal ideation and suicide attempts. The data comes from recordings of psychiatric interviews collected in three psychiatric hospitals in Poland. Assuming a constructionist view of discourse we argue that the literature on suicide ignores and simplifies the experience of those who think about suicide and attempt to commit it, and constructs their experiences as a homogeneous group of 'thoughts' with only limited content. We also offer a preliminary insight into the complexity of 'suicide thoughts', as narrated by those reporting them. We demonstrate that they are marginalized and made relatively irrelevant in the accounts of attempted suicide. Additionally, we demonstrate that while women construct suicide attempts (whether actually attempted in the end or not) as at least potentially beyond their control, men's narratives show them in control of the attempt, as if choosing an available option. We conclude by exploring possibilities of further qualitative discourse analytic research which builds on the findings we present here.

Thermal control is a generic need for all spacecraft. In response to ever more demanding science and exploration requirements, spacecraft are becoming ever more complex, and hence their thermal control systems must evolve. This paper briefly discusses the process of technology development, the state-of-the-art in thermal control, recent experiences with on-orbit two-phase systems, and the emerging thermal control technologies to meet these evolving needs. Some "lessons learned" based on experience with on-orbit systems are also presented.

With modest modifications to the planned future Constellation vehicle (i.e., the Orion Crew Exploration Vehicle), astronomers, and other scientist can anticipate major scientific accomplishments that would not otherwise be possible. Much of this can be attributed to the experience gained from the International Space Station Construction and the Hubble Space Telescope servicing missions.

Crush-2: Communicating research through a science-art collaboration

2011-12-01

Historically, the Earth's environment and dynamics have influenced and inspired the arts. Art in turn is a powerful vehicle for expression of the natural world. It lends itself to public presentation in many forms and appeals to a diverse audience. Science-art collaborations provide a unique opportunity to connect with the public by taking science out of the classroom and into museums, galleries and public spaces. Here we investigate the use of contemporary digital sound-art in communicating geoscience research to the general public through the installation Crush-2. Crush-2, is an interactive sound-art installation exploring the microscopic forces released during the crushing of rock. Such processes have a strong influence on the sliding behaviour and hence earthquake potential of active faults. This work is a collaboration between sound artist and composer Natasha Barrett (Oslo) and geoscientists Karen Mair (University of Oslo), Alexandre Schubnel (Ecole Normale Superieure, Paris) and Steffen Abe (RWTH Aachen). Using a sonification technique, Barrett has assigned sound recorded from rocks, of different pitches, timbres and durations, to individual fracturing events produced in our 3D fault fragmentation models and laboratory rock breaking experiments. In addition, ultrasonic acoustic emissions recorded directly in the laboratory are made audible for our hearing and feature in the work. The installation space comprises a loudspeaker array and sensor enabled helmet with wireless headphones. By wearing the helmet, moving and listening, the audience explores an artistic interpretation of the scientific data in physical space. On entering the space, one is immediately immersed in a 3D cacophony of sound. Sustained or intermittent pings, burrs, plops and tingles jostle for position in our heads whilst high pitched delicate cascades juxtapose with deep thunder like rumbles. Depending on the user's precise path through the soundscape, the experience changes accordingly, so every visitor has a unique sound adventure. The experience is intensely engaging, playful and yet a little unsettling and provides a truly unique way to explore our scientific data and present geoscience research to the public. Crush-2 has featured in an exhibition on Sonic Interaction Design at the Norwegian Museum of Science, Technology and Medicine, Oslo, Norway (27 May - 21 August 2011) and forms part of a solo exhibition by Barrett at Galleri ROM, Oslo in fall 2011. Visitor feedback from the Museum exhibition suggests that users were initially attracted to the exhibit by its interactive 'hands-on' nature and dramatic sounds, but as they 'explored' the soundspace, became curious to ask questions about the underlying science. The concept of using sound rather than visual gives an unusual and therefore highly memorable experience. This science-art collaboration provides a novel and highly enjoyable way to present our work to the public - that is particularly attractive to youngsters. Visitors to this poster presentation will be able to explore the Crush-2 soundscape using a laptop and headphone interactive mode.

This colorful booklet presents capsule information on every aspect of the International Microgravity Laboratory (IML). As part of Spacelab, IML is divided into Life Science Experiments and Materials Science Experiments. Because the life and materials sciences use different Spacelab resources, they are logically paired on the IML missions. Life science investigations generally require significant crew involvement, and crew members often participate as test subjects or operators. Materials missions capitalize on these complementary experiments. International cooperation consists in participation by the European Space Agency, Canada, France, Germany, and Japan who are all partners in developing hardware and experiments of IML missions. IML experiments are crucial to future space ventures, like the development of Space Station Freedom, the establishment of lunar colonies, and the exploration of other planets. Principal investigators are identified for each experiment.

Humanoid infers Archimedes' principle: understanding physical relations and object affordances through cumulative learning experiences

PubMed Central

2016-01-01

Emerging studies indicate that several species such as corvids, apes and children solve ‘The Crow and the Pitcher’ task (from Aesop's Fables) in diverse conditions. Hidden beneath this fascinating paradigm is a fundamental question: by cumulatively interacting with different objects, how can an agent abstract the underlying cause–effect relations to predict and creatively exploit potential affordances of novel objects in the context of sought goals? Re-enacting this Aesop's Fable task on a humanoid within an open-ended ‘learning–prediction–abstraction’ loop, we address this problem and (i) present a brain-guided neural framework that emulates rapid one-shot encoding of ongoing experiences into a long-term memory and (ii) propose four task-agnostic learning rules (elimination, growth, uncertainty and status quo) that correlate predictions from remembered past experiences with the unfolding present situation to gradually abstract the underlying causal relations. Driven by the proposed architecture, the ensuing robot behaviours illustrated causal learning and anticipation similar to natural agents. Results further demonstrate that by cumulatively interacting with few objects, the predictions of the robot in case of novel objects converge close to the physical law, i.e. the Archimedes principle: this being independent of both the objects explored during learning and the order of their cumulative exploration.

Spatial covert attention increases contrast sensitivity across the CSF: support for signal enhancement

Carrasco, M.; Penpeci-Talgar, C.; Eckstein, M.

2000-01-01

This study is the first to report the benefits of spatial covert attention on contrast sensitivity in a wide range of spatial frequencies when a target alone was presented in the absence of a local post-mask. We used a peripheral precue (a small circle indicating the target location) to explore the effects of covert spatial attention on contrast sensitivity as assessed by orientation discrimination (Experiments 1-4), detection (Experiments 2 and 3) and localization (Experiment 3) tasks. In all four experiments the target (a Gabor patch ranging in spatial frequency from 0.5 to 10 cpd) was presented alone in one of eight possible locations equidistant from fixation. Contrast sensitivity was consistently higher for peripherally- than for neutrally-cued trials, even though we eliminated variables (distracters, global masks, local masks, and location uncertainty) that are known to contribute to an external noise reduction explanation of attention. When observers were presented with vertical and horizontal Gabor patches an external noise reduction signal detection model accounted for the cueing benefit in a discrimination task (Experiment 1). However, such a model could not account for this benefit when location uncertainty was reduced, either by: (a) Increasing overall performance level (Experiment 2); (b) increasing stimulus contrast to enable fine discriminations of slightly tilted suprathreshold stimuli (Experiment 3); and (c) presenting a local post-mask (Experiment 4). Given that attentional benefits occurred under conditions that exclude all variables predicted by the external noise reduction model, these results support the signal enhancement model of attention.

Employing a set of experiments devoted to examining the effect of surface finish (riblets) on convective heat transfer as an example, this technical note seeks to explore the notion that precision uncertainties in experiments can be reduced by repeated trials and averaging. This scheme for bias error reduction can give considerable advantage when parametric effects are investigated experimentally. When the results of an experiment are presented as a ratio with the baseline results, a large reduction in the overall uncertainty can be achieved when all the bias limits in the variables of the experimental result are fully correlated with thosemore » of the baseline case. 4 refs.« less

The scientific goal of the CBM (Compressed Baryonic Matter) experiment at FAIR (Darmstadt) is to explore the phase diagram of strongly interacting matter at highest baryon densities. The physics program of the CBM experiment is complimentary to the programs to be realized at MPD and BMN facilities at NICA and will start with beam derived by the SIS100 synchrotron. The 5.15 MJ superconducting dipole magnet will be used in the silicon tracking system of the CBM detector. The magnet will provide a magnetic field integral of 1 Tm which is required to obtain a momentum resolution of 1% for the track reconstruction. The results of the development of dipole magnet of the CBM experiment are presented.

Being a Student of Teacher Researcher Experiences (SoTRE), gets students excited for science. Eubanks brings real, current science to the classroom because of time spent in Teacher Researcher Experiences (TRE), where she works with researchers in and out of the field. She involves students in many programs including the National Oceanographic and Atmospheric Administration (NOAA), Polar TREC (Teachers and Researchers & Exploring & Collaboration), National Science Foundation (NSF) funded researchers, (EARTH) Education and Research: Testing Hypothesis, the RJ Dunlap Marine Conservation Program, C-DEBI (Center for Dark Energy Biosphere Investigations and (STARS) Sending Teachers Aboard Research Ships. Being in these programs gives students special privileges such as understanding unique research ideas, tracking tagged sharks, following daily journals written on location, taking part in cross-continental experiments, tracking real time data, exploring current research via posters or visiting universities. Furthermore, contacts made by a TRE give students an added set of resources. When doing experiments for class or advancing their education or career goals, Mrs. Eubanks helps students connect with scientists. This gives students a unique opportunity to learn from real scientists. Being part of these relationships with NOAA, Polar TREC, EARTH, RJ Dunlap, STARS and NSF funded scientists who are actively working, makes being SoTRE the ultimate learning experience. Many students have felt so strongly about the TRE relationship that they have presented at several local and international science conferences. Their message is to encourage scientists to partner with teachers. The benefits of participation in such conferences have included abstract writing and submission, travel, poster creation, networking and presentation, all tools that they will carry with them for a lifetime.

Facilitating transitions. Nursing support for parents during the transfer of preterm infants between neonatal nurseries.

PubMed

Rowe, Jennifer; Jones, Liz

2008-03-01

Transfers between neonatal units are significant transitional experiences for parents of preterm infants. The study aimed to investigate practices that nurses identify as supportive to parents during preterm infants' transfers. It explored the influence of organisational context on practice and what strategies nurses perceive would help them to provide supportive care. Parents' experiences of neonatal nurseries, their stressors and needs have been well documented. The powerful position of nurses in influencing parenting experience is also recognised. However, nurses' understanding of the transfer process, their roles in supporting parents through this and the organisational context influencing practice have not been explored. A focus group design was used composed of registered nurses from two neonatal units who met for a series of group interviews. Eleven registered nurses participated. They explored and critiqued their current practices and then established aims and strategies for practice development. A qualitative content analysis was conducted. Participants identified validation, empowerment and communication as critical to effective practice. They identified a range of organisational dynamics, from logistical issues to nursing authority and scope of practice, as these influenced practice. They presented strategies for practice development, including staff education and the development of nurse practitioner roles. This study explores nurses' understanding and insights into transitions for parents of preterm infants. It shows a congruence between nurses' perceptions of parents' experiences and needs and those reported by parents in previous studies. It articulates the way nurses practice in response to these perceptions, and the manner in which organisational dynamics influence their ability to facilitate transitions. The need to invest in transitions and invest in nurses to facilitate transitions is proposed, ultimately by increasing their clinical authority and autonomy.

Why seek a second consultation at an emergency centre? A qualitative study

PubMed Central

2017-01-01

Background The inappropriate use of emergency centres (ECs) is an expanding problem globally. The high attendance of non-urgent return presentations to ECs is recognised as part of the problem, placing an unnecessary demand on limited staff and resources. Of unscheduled returns 34% of cases had no change to diagnosis or treatment with the conclusion that 80% of re-attendance could be attributed to deficiencies in the initial consultation. This study aimed to evaluate the reasons why patients sought an early second consultation for the same complaint at a hospital EC in South Africa, by exploring the patient’s experience and shortcomings in the first consultation. Method A qualitative study was conducted using in-depth, semi-structured interviews with 20 purposively selected participants who presented to a rural regional provincial hospital’s EC within 7 days of a prior consultation for the same complaint. Verbatim transcripts were analysed using the framework method. Results The main reasons for a second consultation were symptom related factors and the need for diagnostic certainty. The major themes around patient experience of the initial consultation were shortcomings in effective evaluation and management of pain, diagnostic uncertainty including poor examination, poor explanation, uncertain access and follow-up and societal encouragement to utilise a hospital EC. Conclusion Further interventions should explore pain as a presenting symptom of the illness experience, and promote competence in addressing physical and psychological causative factors within a patient-centred approach for all health staff, especially in primary care services.

To investigate cardiovascular nurses' experiences of and attitudes towards the presence of family members during resuscitation of adult patients. A 36-item questionnaire exploring the experiences of and attitudes towards family members being present in the resuscitation room was distributed to a convenience sample of nurses attending three national and one international cardiovascular nursing conferences held in Europe during 2007. Of 820 questionnaires distributed, 411(50%) completed ones were returned. Of these 411 respondents, 178 (44%) had experienced at least one situation of families being present. Positive (23%) and negative (21%) experiences of family presence were equally distributed. Only 28 (7%) respondents stated that their unit had a protocol covering family presence. Nurses in Ireland (n=30; 59%) and the UK (n=18; 55%) were most likely to have experienced family presence and protocols relating to this were most commonly found in the UK (n=4; 14%). Less than half of the included European cardiovascular nurses had experienced a situation of families being present during resuscitation and protocols pertaining to this were rare. There was no clear attitude towards family presence, though experience in nursing made nurses more favourable towards it. Copyright (c) 2009 European Society of Cardiology. Published by Elsevier B.V.

The role of language in the experience and perception of emotion: a neuroimaging meta-analysis

PubMed Central

Brooks, Jeffrey A.; Shablack, Holly; Gendron, Maria; Satpute, Ajay B.; Parrish, Michael H.

2017-01-01

Abstract Recent behavioral and neuroimaging studies demonstrate that labeling one’s emotional experiences and perceptions alters those states. Here, we used a comprehensive meta-analysis of the neuroimaging literature to systematically explore whether the presence of emotion words in experimental tasks has an impact on the neural representation of emotional experiences and perceptions across studies. Using a database of 386 studies, we assessed brain activity when emotion words (e.g. ‘anger’, ‘disgust’) and more general affect words (e.g. ‘pleasant’, ‘unpleasant’) were present in experimental tasks vs not present. As predicted, when emotion words were present, we observed more frequent activations in regions related to semantic processing. When emotion words were not present, we observed more frequent activations in the amygdala and parahippocampal gyrus, bilaterally. The presence of affect words did not have the same effect on the neural representation of emotional experiences and perceptions, suggesting that our observed effects are specific to emotion words. These findings are consistent with the psychological constructionist prediction that in the absence of accessible emotion concepts, the meaning of affective experiences and perceptions are ambiguous. Findings are also consistent with the regulatory role of ‘affect labeling’. Implications of the role of language in emotion construction and regulation are discussed. PMID:27539864
