Differential-associative processing or example elaboration: Which strategy is best for learning the definitions of related and unrelated concepts?

PubMed Central

2013-01-01

Definitions of related concepts (e.g., genotype–phenotype) are prevalent in introductory classes. Consequently, it is important that educators and students know which strategy(s) work best for learning them. This study showed that a new comparative elaboration strategy, called differential-associative processing, was better for learning definitions of related concepts than was an integrative elaborative strategy, called example elaboration. This outcome occurred even though example elaboration was administered in a naturalistic way (Experiment 1) and students spent more time in the example elaboration condition learning (Experiments 1, 2, 3), and generating pieces of information about the concepts (Experiments 2 and 3). Further, with unrelated concepts (morpheme-fluid intelligence), performance was similar regardless if students used differential-associative processing or example elaboration (Experiment 3). Taken as a whole, these results suggest that differential-associative processing is better than example elaboration for learning definitions of related concepts and is as good as example elaboration for learning definitions of unrelated concepts.

Satellite Power System (SPS) concept definition study (exhibit C)

NASA Technical Reports Server (NTRS)

Haley, G. M.

1979-01-01

The major outputs of the study are the constructability studies which resulted in the definition of the concepts for satellite, rectenna, and satellite construction base construction. Transportation analyses resulted in definition of heavy-lift launch vehicle, electric orbit transfer vehicle, personnel orbit transfer vehicle, and intra-orbit transfer vehicle as well as overall operations related to transportation systems. The experiment/verification program definition resulted in the definition of elements for the Ground-Based Experimental Research and Key Technology plans. These studies also resulted in conceptual approaches for early space technology verification. The cost analysis defined the overall program and cost data for all program elements and phases.

Testing Alternative Definitions of Chronic Homelessness.

PubMed

Byrne, Thomas; Culhane, Dennis P

2015-09-01

This study examined the potential impact of a proposed change to the official federal definition of chronic homelessness. Using administrative data from the emergency shelters in a large U.S. city, this study estimated the number of persons identified as chronically homeless under the current definition of chronic homelessness, a proposed new federal definition, and two alternative definitions and examined shelter utilization for each group. Fewer than half as many people were considered chronically homeless under the proposed new federal definition compared with the current definition. Persons considered chronically homeless by the proposed new definition and, to a lesser extent, by the two alternative definitions, made heavier use of shelter compared with persons who met the current definition. A proposed new and two alternative definitions of chronic homelessness are better suited than the existing federal definition for identifying persons with the most protracted experiences of homelessness.

Russell, R. A.

1988-01-01

A system study to develop the definition of a structural flight experiment for a large precision segmented reflector on the Space Station was accomplished by the Boeing Aerospace Company for NASA's Langley Research Center. The objective of the study was to use a Large Deployable Reflector (LDR) baseline configuration as the basis for focusing an experiment definition, so that the resulting accommodation requirements and interface constraints could be used as part of the mission requirements data base for Space Station. The primary objectives of the first experiment are to construct the primary mirror support truss and to determine its structural and thermal characteristics. Addition of an optical bench, thermal shield and primary mirror segments, and alignment of the optical components, would occur on a second experiment. The structure would then be moved to the payload point system for pointing, optical control, and scientific optical measurement for a third experiment. Experiment 1 will deploy the primary support truss while it is attached to the instrument module structure. The ability to adjust the mirror attachment points and to attach several dummy primary mirror segments with a robotic system will also be demonstrated. Experiment 2 will be achieved by adding new components and equipment to experiment one. Experiment 3 will demonstrate advanced control strategies, active adjustment of the primary mirror alignment, and technologies associated with optical sensing.

Scoping studies (or reviews) are a method used to comprehensively map evidence across a range of study designs in an area, with the aim of informing future research practice, programs and policy. However, no universal agreement exists on terminology, definition or methodological steps. Our aim was to understand the experiences of, and considerations for conducting scoping studies from the perspective of academic and community partners. Primary objectives were to 1) describe experiences conducting scoping studies including strengths and challenges; and 2) describe perspectives on terminology, definition, and methodological steps. We conducted a cross-sectional web-based survey with clinicians, educators, researchers, knowledge users, representatives from community-based organizations, graduate students, and policy stakeholders with experience and/or interest in conducting scoping studies to gain an understanding of experiences and perspectives on the conduct and reporting of scoping studies. We administered an electronic self-reported questionnaire comprised of 22 items related to experiences with scoping studies, strengths and challenges, opinions on terminology, and methodological steps. We analyzed questionnaire data using descriptive statistics and content analytical techniques. Survey results were discussed during a multi-stakeholder consultation to identify key considerations in the conduct and reporting of scoping studies. Of the 83 invitations, 54 individuals (65 %) completed the scoping questionnaire, and 48 (58 %) attended the scoping study meeting from Canada, the United Kingdom and United States. Many scoping study strengths were dually identified as challenges including breadth of scope, and iterative process. No consensus on terminology emerged, however key defining features that comprised a working definition of scoping studies included the exploratory mapping of literature in a field; iterative process, inclusion of grey literature; no quality assessment of included studies, and an optional consultation phase. We offer considerations for the conduct and reporting of scoping studies for researchers, clinicians and knowledge users engaging in this methodology. Lack of consensus on scoping terminology, definition and methodological steps persists. Reasons for this may be attributed to diversity of disciplines adopting this methodology for differing purposes. Further work is needed to establish guidelines on the reporting and methodological quality assessment of scoping studies.

Line integral on engineering mathematics

Definite integral is a basic material in studying mathematics. At the level of calculus, calculating of definite integral is based on fundamental theorem of calculus, related to anti-derivative, as the inverse operation of derivative. At the higher level such as engineering mathematics, the definite integral is used as one of the calculating tools of line integral. the purpose of this is to identify if there is a question related to line integral, we can use definite integral as one of the calculating experience. The conclusion of this research says that the teaching experience in introducing the relation between both integrals through the engineer way of thinking can motivate and improve students in understanding the material.

Building a Definition of Irritability From Academic Definitions and Lay Descriptions.

Barata, Paula C; Holtzman, Susan; Cunningham, Shannon; O'Connor, Brian P; Stewart, Donna E

2016-04-08

The current work builds a definition of irritability from both academic definitions and lay perspectives. In Study 1, a quantitative content analysis of academic definitions resulted in eight main content categories (i.e., behaviour, emotion or affect, cognition, physiological, qualifiers, irritant, stability or endurance, and other). In Study 2, a community sample of 39 adults participated in qualitative interviews. A deductive thematic analysis resulted in two main themes. The first main theme dealt with how participants positioned irritability in relation to other negative states. The second dealt with how participants constructed irritability as both a loss of control and as an experience that should be controlled. The discussion integrates the findings of both studies and provides a concise, but comprehensive definition.

The stability of materials used in the space environment will continue to be a limiting technology for space missions. The Optical Properties Monitor (OPM) Experiment provides a comprehensive space research program to study the effects of the space environment (both natural and induced) on optical, thermal and space power materials. The OPM Experiment was selected for definition under the NASA/OAST In-Space Technology Experiment Program. The results of the OPM Definition Phase are presented. The OPM experiment will expose selected materials to the space environment and measure the effects with in-space optical measurements. In-space measurements include total hemispherical reflectance total integrated scatter and VUV reflectance/transmittance. The in-space measurements will be augmented with extensive pre- and post-flight sample measurements to determine other optical, mechanical, electrical, chemical or surface effects of space exposure. Environmental monitors will provide the amount and time history of the sample exposure to solar irradiation, atomic oxygen and molecular contamination.

Verbal definitions of familiar objects in blind children reflect their peculiar perceptual experience.

Vinter, A; Fernandes, V; Orlandi, O; Morgan, P

2013-11-01

The aim of the present study was to examine to what extent the verbal definitions of familiar objects produced by blind children reflect their peculiar perceptual experience and, in consequence, differ from those produced by sighted children. Ninety-six visually impaired children, aged between 6 and 14 years, and 32 age-matched sighted children had to define 10 words denoting concrete animate or inanimate familiar objects. The blind children evoked the tactile and auditory characteristics of objects and expressed personal perceptual experiences in their definitions. The sighted children relied on visual perception, and produced more visually oriented verbalism. In contrast, no differences were observed between children in their propensity to include functional attributes in their verbal definitions. The results are discussed in line with embodied views of cognition that postulate mandatory perceptuomotor processing of words during access to their meaning. © 2012 John Wiley & Sons Ltd.

Collaborative testing for key-term definitions under representative conditions: Efficiency costs and no learning benefits.

PubMed

Wissman, Kathryn T; Rawson, Katherine A

2018-01-01

Students are expected to learn key-term definitions across many different grade levels and academic disciplines. Thus, investigating ways to promote understanding of key-term definitions is of critical importance for applied purposes. A recent survey showed that learners report engaging in collaborative practice testing when learning key-term definitions, with outcomes also shedding light on the way in which learners report engaging in collaborative testing in real-world contexts (Wissman & Rawson, 2016, Memory, 24, 223-239). However, no research has directly explored the effectiveness of engaging in collaborative testing under representative conditions. Accordingly, the current research evaluates the costs (with respect to efficiency) and the benefits (with respect to learning) of collaborative testing for key-term definitions under representative conditions. In three experiments (ns = 94, 74, 95), learners individually studied key-term definitions and then completed retrieval practice, which occurred either individually or collaboratively (in dyads). Two days later, all learners completed a final individual test. Results from Experiments 1-2 showed a cost (with respect to efficiency) and no benefit (with respect to learning) of engaging in collaborative testing for key-term definitions. Experiment 3 evaluated a theoretical explanation for why collaborative benefits do not emerge under representative conditions. Collectively, outcomes indicate that collaborative testing versus individual testing is less effective and less efficient when learning key-term definitions under representative conditions.

Improving college students' evaluation of text learning using idea-unit standards.

2011-03-01

When recalling key definitions from class materials, college students are often overconfident in the quality of their responses. Even with commission errors, they often judge that their response is entirely or partially correct. To further understand this overconfidence, we investigated whether idea-unit judgements would reduce overconfidence (Experiments 1 and 2) and whether students inflated their scores because they believed that they knew answers but just responded incorrectly (Experiment 2). College students studied key-term definitions and later attempted to recall each definition when given the key term (e.g., What is the availability heuristic?). All students judged the quality of their recall, but some were given a full-definition standard to use, whereas other students first judged whether their response included each of the individual ideas within the corresponding correct answer. In Experiment 1, making these idea-unit judgements reduced overconfidence for commission errors. In Experiment 2, some students were given the correct definitions and graded other students' responses, and some students generated idea units themselves before judging their responses. Students were overconfident even when they graded other students' responses, and, as important, self-generated idea units for each definition also reduced overconfidence in commission errors. Thus, overconfidence appears to result from difficulties in evaluating the quality of recall responses, and such overconfidence can be reduced by using idea-unit judgements.

Emotional complexity: Clarifying definitions and cultural correlates.

PubMed

Grossmann, Igor; Huynh, Alex C; Ellsworth, Phoebe C

2016-12-01

There is much debate about the notion of emotional complexity (EC). The debate concerns both the definition and the meaning of ostensible cultural differences in the construct. Some scholars have defined EC as the experience of positive and negative emotions together rather than as opposites, a phenomenon that seems more common in East Asia than North America. Others have defined EC as the experience of emotions in a differentiated manner, a definition that has yet to be explored cross-culturally. The present research explores the role of dialectical beliefs and interdependence in explaining cultural differences in EC according to both definitions. In Study 1, we examined the prevalence of mixed (positive-negative) emotions in English-language online texts from 10 countries varying in interdependence and dialecticism. In Studies 2-3, we examined reports of emotional experiences in 6 countries, comparing intraindividual associations between pleasant and unpleasant states, prevalence of mixed emotions, and emotional differentiation across and within-situations. Overall, interdependence accounted for more cross-cultural and individual variance in EC measures than did dialecticism. Moreover, emotional differentiation was associated with the experience of positive and negative emotions together rather than as opposites, but only when tested on the same level of analysis (i.e., within vs. across-situations).

The DSM-5 includes a revised definition of the experiences that qualify as potentially traumatic events. This revised definition now offers a clearer and more exclusive definition of what qualifies as a traumatic exposure, but little is known about the revision's applicability to youth populations. The present study evaluated the predictive utility of the revised DSM definitional boundaries of traumatic exposure in a sample of youth exposed to the 2013 Boston Marathon bombing and related events METHODS: Caregivers (N = 460) completed surveys 2 to 6 months postbombing about youth experiences during the events and youth posttraumatic stress (PTS) symptoms RESULTS: Experiencing DSM-5 qualifying traumatic events (DSM-5 QTEs) significantly predicted child PTS symptoms (PTSS), whereas DSM-5 nonqualifying stressful experiences (DSM-5 non-QSEs) did not after accounting for DSM-5 QTEs. Importantly, child age moderated the relationship between DSM-5 QTEs and PTSS such that children 7 and older who experienced DSM-5 QTEs showed greater postbombing PTSS, whereas there was no such relationship in children ages 6 and below CONCLUSIONS: Data largely support the revised posttraumatic stress disorder (PTSD) definition of QTEs in older youth, and also highlight the need for further refinement of the QTE definition for children ages 6 and below. © 2016 Wiley Periodicals, Inc.

Experimental investigations of weak definite and weak indefinite noun phrases

PubMed Central

Klein, Natalie M.; Gegg-Harrison, Whitney M.; Carlson, Greg N.; Tanenhaus, Michael K.

2013-01-01

Definite noun phrases typically refer to entities that are uniquely identifiable in the speaker and addressee’s common ground. Some definite noun phrases (e.g. the hospital in Mary had to go the hospital and John did too) seem to violate this uniqueness constraint. We report six experiments that were motivated by the hypothesis that these “weak definite” interpretations arise in “incorporated” constructions. Experiments 1-3 compared nouns that seem to allow for a weak definite interpretation (e.g. hospital, bank, bus, radio) with those that do not (e.g. farm, concert, car, book). Experiments 1 and 2 used an instruction-following task and picture-judgment task, respectively, to demonstrate that a weak definite need not uniquely refer. In Experiment 3 participants imagined scenarios described by sentences such as The Federal Express driver had to go to the hospital/farm. The imagined scenarios following weak definite noun phrases were more likely to include conventional activities associated with the object, whereas following regular nouns, participants were more likely to imagine scenarios that included typical activities associated with the subject; similar effects were observed with weak indefinites. Experiment 4 found that object-related activities were reduced when the same subject and object were used with a verb that does not license weak definite interpretations. In Experiment 5, a science fiction story introduced an artificial lexicon for novel concepts. Novel nouns that shared conceptual properties with English weak definite nouns were more likely to allow weak reference in a judgment task. Experiment 6 demonstrated that familiarity for definite articles and anti- familiarity for indefinite articles applies to the activity associated with the noun, consistent with predictions made by the incorporation analysis.

The Gas-Grain Simulation Facility (GGSF) is a facility-type payload to be included in the Space Station Freedom (SSF). The GGSF is a multidisciplinary facility that will accommodate several classes of experiments, including exobiology, planetary science, atmospheric science, and astrophysics. The physical mechanisms envisioned to be investigated include crystal growth, aggregation, nucleation, coagulation, condensation, collisions, fractal growth, cycles of freezing and evaporation, scavenging, longevity of bacteria, and more. TRW performed a Phase A study that included analyses of the science and technical (S&T) requirements, the development of facility functional requirements, and a conceptual design of the facility. The work that was performed under Stage 1 of the Phase A study and the results to date are summarized. In this stage, facility definition studies were conducted in sufficient detail to establish the technical feasibility of the candidate strawman experiments. The studies identified technical difficulties, identified required facility subsystems, surveyed existing technology studies and established preliminary facility weight, volume, power consumption, data systems, interface definition, and crew time requirements. The results of this study served as the basis for Stage 2 of the Phase A study in which a conceptual design and a reference design were performed. The results also served as a basis for a related study for a Gas-Grain Simulation Experiment Module (GGSEM), which is an apparatus intended to perform a subset of the GGSF experiments on board a low-Earth-orbiting platform.

Kim, Jiyoun; Akin, Heather; Brossard, Dominique; Xenos, Michael; Scheufele, Dietram A.

2017-05-01

This study examines how familiarity with an issue—nanotechnology—moderates the effect of exposure to science information on how people process mediated messages about a complex issue. In an online experiment, we provide a nationally representative sample three definitions of nanotechnology (technical, technical applications, and technical risk/benefit definitions). We then ask them to read an article about the topic. We find significant interactions between perceived nano-familiarity and the definition received in terms of how respondents perceive favorable information conveyed in the stimulus. People less familiar with nanotechnology were more significantly affected by the type of definition they received.

2018-02-01

In order to protect medical students from burnout and its untoward psychiatric effects, it is imperative to understand their stress, burnout, coping, and resilience experiences. This study aimed to derive collective definitions from the medical student perspective, to identify common themes of students' experiences, and to distinguish pre-clinical and clinical year students' experiences relating to these four constructs. The authors conducted focus groups of medical students in Singapore across 4 years using a semi-structured question guide. Participants shared their understanding, experiences, and the relationships between stress, burnout, coping, and resilience. Coders independently evaluated construct definitions and derived common themes through an iterative process, and compared transcripts of pre-clinical and clinical year students to determine differences in experience over time. Nine focus groups (54 students, 28 females, mean age 24.3) were conducted. Students identified common definitions for each construct. Nine themes emerged within three domains: (1) relating constructs to personal experience, (2) interrelating stress, burnout, coping, and resilience, and (3) understanding the necessity of stress. Compared to clinical students, pre-clinical students reported theory-based rather than reality-based experiences and exam-induced stress, defined constructs using present rather than future situations, and described constructs as independent rather than interrelated. This sample of medical students in Singapore shares a common understanding of stress, burnout, coping, and resilience, but experiences these uniquely. They perceive a positive role for stress. These findings build upon prior literature, suggesting an interrelationship between stress and its related constructs and adding the novel perspective of students from an Asian country.

A biomedical and feminist perspective on women's experiences with weight management.

PubMed

Allan, J D

1994-10-01

Weight concerns and dieting have become so normative for U.S. women that weight is the lens through which experience is viewed. The obsession with weight and dieting among women is considered by feminists to be one result of the oppression by women resulting from questionable weight standards and weight control programs that foster a view of overweight as a sign of addiction and lack of control. Feminist critique is used to deconstruct both the literature related to weight standards and health and the research on weight loss/weight management. Feminist and ethnographic methods are used to describe successful and unsuccessful experiences with weight management of 20 Euro-American women who had participated in a 1985 weight study and agreed to be reinterviewed. Success at weight management was examined from a biomedical perspective using Body Mass Index (BMI) norms and from a feminist perspective using participants' subjective definitions of success. Based upon BMI, only 8 members of the study group were defined as successful, whereas based upon the women's perspectives, 11 members were successful. Participants' definitions of successful weight management were divergent from biomedical definitions and could be categorized into three perspectives: biomedical, reframed normal weight, and holistic. Women who ascribed to the biomedical definition of success embodied the cultural ideal of thinness by adhering to an underweight weight norm. Participants using the reframed normal weight definition of success rejected biomedical weight norms and created their own weight norms. The holistic perspective on success involved the use of a broader, health-focused definition of successful weight management and offers some directions for revising current health promotion care relative to weight.

Although infertility causes women considerable grief, social stigma, and economic deprivation, scholars have paid little attention to infertility's definitions that may depart from the standard Western usage and how such definitions influence the way women experience the condition. This article, by listening to individual women's experiences of infertility in two Nigerian communities, examines these definitions and differentiates between culturally salient categories of infertility. In distinguishing between different kinds of childless women and those with low fertility, we intend to enhance understandings of infertility by considering women's subjective understandings of the condition and thus moving beyond the current medical definition. By comparing women's experiences in two different ethnic groups in Nigeria, we show how distinct forms of kinship structures and social organizations shape the ways low fertility is defined, managed, and experienced. © 2013 by the American Anthropological Association.

The Experience of Mothers Exposed to the Abuse of Their Daughters by an Intimate Partner: "There Is No Definition for It".

PubMed

Peled, Einat; Gueta, Keren; Sander-Almoznino, Nili

2016-11-01

This qualitative study illuminates the experience of mothers exposed to the intimate partner violence (IPV) of their daughters. In-depth interviews with 11 exposed mothers were conducted. The findings reveal four semi-chronological phases in the participants' experiences: pre-disclosure of the daughter's abuse, the first definitive encounter with the daughter's abuse, living with continued exposure to the daughter's IPV, and the aftermath of the daughter's IPV. A recurrent theme in the mothers' experiences was their dual positioning as a forgotten victim of IPV and as a caregiver of their daughter shaped by prevalent motherhood ideologies. Possible implications for intervention are discussed. © The Author(s) 2016.

STS flight experiments and space station experiments needed to provide onorbit validation of the evolving technology.

Definition of major bleeding in clinical investigations of antihemostatic medicinal products in surgical patients.

PubMed

Schulman, S; Angerås, U; Bergqvist, D; Eriksson, B; Lassen, M R; Fisher, W

2010-01-01

The definition of major bleeding varies between studies on surgical patients, particularly regarding the criteria for surgical wound-related bleeding. This diversity contributes to the difficulties in comparing data between trials. The Scientific and Standardization Committee (SSC), through its subcommittee on Control of Anticoagulation, of the International Society on Thrombosis and Haemostasis has previously published a recommendation for a harmonized definition of major bleeding in non-surgical studies. That definition has been adopted by the European Medicines Agency and is currently used in several non-surgical trials. A preliminary proposal for a parallel definition for surgical studies was presented at the 54(th) Annual Meeting of the SSC in Vienna, July 2008. Based on those discussions and further consultations with European and North American surgeons with experience from clinical trials a definition has been developed that should be applicable to all agents that interfere with hemostasis. The definition and the text that follows have been reviewed and approved by relevant co-chairs of the subcommittee and by the Executive Committee of the SSC. The intention is to seek approval of this definition from the regulatory authorities to enhance its incorporation into future clinical trial protocols.

Exploring definitions of financial abuse in elderly Korean immigrants: the contribution of traditional cultural values.

PubMed

Lee, Hee Yun; Lee, Sang E; Eaton, Charissa K

2012-10-01

The purpose of this study is to explore the cultural definitions of financial abuse from the perspective of 124 elderly Korean immigrants and to examine the role of traditional cultural values in their definitions by using a mixed methods approach. The qualitative analysis generated four themes relevant to definition of financial abuse. A binary logistic regression indicated that those with stronger cultural adherence to traditional values had higher odds of providing culture-based definitions of financial abuse. Education is needed for health professionals, social service providers, and adult protective workers to increase their understanding of culture-specific experiences of financial abuse among ethnic minority elders.

A Framework to Support the Sharing and Reuse of Computable Phenotype Definitions Across Health Care Delivery and Clinical Research Applications.

Richesson, Rachel L; Smerek, Michelle M; Blake Cameron, C

2016-01-01

The ability to reproducibly identify clinically equivalent patient populations is critical to the vision of learning health care systems that implement and evaluate evidence-based treatments. The use of common or semantically equivalent phenotype definitions across research and health care use cases will support this aim. Currently, there is no single consolidated repository for computable phenotype definitions, making it difficult to find all definitions that already exist, and also hindering the sharing of definitions between user groups. Drawing from our experience in an academic medical center that supports a number of multisite research projects and quality improvement studies, we articulate a framework that will support the sharing of phenotype definitions across research and health care use cases, and highlight gaps and areas that need attention and collaborative solutions. An infrastructure for re-using computable phenotype definitions and sharing experience across health care delivery and clinical research applications includes: access to a collection of existing phenotype definitions, information to evaluate their appropriateness for particular applications, a knowledge base of implementation guidance, supporting tools that are user-friendly and intuitive, and a willingness to use them. We encourage prospective researchers and health administrators to re-use existing EHR-based condition definitions where appropriate and share their results with others to support a national culture of learning health care. There are a number of federally funded resources to support these activities, and research sponsors should encourage their use.

2016-04-01

Although a large number of studies have been conducted worldwide to examine various aspects of intimate partner violence (IPV), comparative study of people's views on such violence in Chinese societies has been scarce. Using survey data collected from more than 850 college students in China, Hong Kong, and Taiwan, this study specifically assessed the impact of attitudes toward gender role and violence, personal and vicarious experience, demographic characteristics, and locality on students' definitions of IPV. The Taiwanese students were most likely to define a broader range of abusive behavior as IPV, followed by Hong Kong and Beijing students. Gender role and violence attitudes appeared to be most important predictors of IPV definitions. College students who supported the notion of male dominance were more likely to have a narrower definition of IPV, whereas those who viewed domestic violence as crime were more inclined to have a broader definition of IPV. Implications for future research and policy were discussed. © The Author(s) 2014.

Sodium sulfur battery flight experiment definition study

NASA Technical Reports Server (NTRS)

Chang, Rebecca R.; Minck, Robert

1989-01-01

Sodium-sulfur batteries were identified as the most likely successor to nickel-hydrogen batteries for space applications. One advantage of the Na/S battery system is that the usable specific energy is two to three times that of nickel-hydrogen batteries. This represents a significant launch cost savings or increased payload mass capabilities. Sodium-sulfur batteries support NASA OAST's proposed Civil Space Technology Initiative goal of a factor of two improvement in spacecraft power system performance, as well as the proposed Spacecraft 2000 initiative. The sodium-sulfur battery operates at between 300 and 400 C, using liquid sodium and sulfur/polysulfide electrodes and solid ceramic electrolyte. The transport of the electrode materials to the surface of the electrolyte is through wicking/capillary forces. These critical transport functions must be demonstrated under actual microgravity conditions before sodium-sulfur batteries can be confidently utilized in space. Ford Aerospace Corporation, under contract to NASA Lewis Research Center, is currently working on the sodium-sulfur battery space flight experiment definition study. The objective is to design the experiment that will demonstrate operation of the sodium-sulfur battery/cell in the space environment with particular emphasis on evaluation of microgravity effects. Experimental payload definitions were completed and preliminary designs of the experiment were defined.

Comparing the Concept of Caring in Islamic Perspective with Watson and Parse's Nursing Theories

2017-01-01

Background: In the nursing profession, it is apparent that the definition of caring differs between various perspectives. This article compares the difference of caring in Islamic with the Parse and Watson theories. Materials and Methods: In this study, we use concept analyses of Walker–Avants and compare research methods. Material used is all Islamic documents. Results: According to Islamic documents, there are four major types of caring, namely, (1) God taking care of humans, (2) Humans taking care of themselves, (3) Other humans taking care of humans, and (4) The universe taking care of humans and vice versa. God caring for humans affects the three other types of caring. All three definitions of caring have humanistic and holistic view. According to Watson's and Parse's definition, the development of the caring theory is based on the person's experiences that result from human interactions with, and experiences of, their environment. In Islamic definition, although the caring process is affected by environmental experiences and interactions, human not developed only base the effect of environment; rather, it is developed on the basis of human nature and divine commands. God taking care of humans is specific to Islamic perspective and is not found in other definitions. Islamic perspective maintains that God is the creator of humanity and is in charge of guiding humans. A superior form of human can always be discovered. Conclusions: Thus, nursing implementation in Muslims must be done based on Islamic commands, and Islamic commands are superior to human experiences. However, Islamic commands interpreted with human wisdom and thought can be striving toward excellence. PMID:28584543

Prevalence and spectrum of residual symptoms in Lyme neuroborreliosis after pharmacological treatment: a systematic review.

PubMed

Dersch, R; Sommer, H; Rauer, S; Meerpohl, J J

2016-01-01

Controversy exists about residual symptoms after pharmacological treatment of Lyme neuroborreliosis. Reports of disabling long-term sequels lead to concerns in patients and health care providers. We systematically reviewed the available evidence from studies reporting treatment of Lyme neuroborreliosis to assess the prevalence and spectrum of residual symptoms after treatment. A literature search was performed in three databases and three clinical trial registers to find eligible studies reporting on residual symptoms in patients after pharmacological treatment of LNB. Diagnosis must have been performed according to consensus-derived case definitions. No restrictions regarding study design or language were set. Symptom prevalence was pooled using a random-effects model. Forty-four eligible clinical trials and studies were found: 8 RCTs, 17 cohort studies, 2 case-control studies, and 17 case series. The follow-up period in the eligible studies ranged from 7 days to 20 years. The weighted mean proportion of residual symptoms was 28 % (95 % CI 23-34 %, n = 34 studies) for the latest reported time point. Prevalence of residual symptoms was statistically significantly higher in studies using the "possible" case definition (p = 0.0048). Cranial neuropathy, pain, paresis, cognitive disturbances, headache, and fatigue were statistically significantly lower in studies using the "probable/definite" case definition. LNB patients may experience residual symptoms after treatment with a prevalence of approximately 28 %. The prevalence and spectrum of residual symptoms differ according to the applied case definition. Symptoms like fatigue are not reported in studies using the "probable/definite" case definition. As the "possible" case definition is more unspecific, patients with other conditions may be included. Reports of debilitating fatigue and cognitive impairment after LNB, a "post-Lyme syndrome", could therefore be an artifact of unspecific case definitions in single studies.

Shuttle-tethered satellite system definition study extension

NASA Technical Reports Server (NTRS)

1980-01-01

A system requirements definition and configuration study (Phase B) of the Tethered Satellite System (TSS) was conducted during the period 14 November 1977 to 27 February 1979. Subsequently a study extension was conducted during the period 13 June 1979 to 30 June 1980, for the purpose of refining the requirements identified during the main phase of the study, and studying in some detail the implications of accommodating various types of scientific experiments on the initial verification flight mission. An executive overview is given of the Tethered Satellite System definition developed during the study. The results of specific study tasks undertaken in the extension phase of the study are reported. Feasibility of the Tethered Satellite System has been established with reasonable confidence and the groundwork laid for proceeding with hardware design for the verification mission.

Inclusion of quasi-experimental studies in systematic reviews of health systems research.

PubMed

Rockers, Peter C; Røttingen, John-Arne; Shemilt, Ian; Tugwell, Peter; Bärnighausen, Till

2015-04-01

Systematic reviews of health systems research commonly limit studies for evidence synthesis to randomized controlled trials. However, well-conducted quasi-experimental studies can provide strong evidence for causal inference. With this article, we aim to stimulate and inform discussions on including quasi-experiments in systematic reviews of health systems research. We define quasi-experimental studies as those that estimate causal effect sizes using exogenous variation in the exposure of interest that is not directly controlled by the researcher. We incorporate this definition into a non-hierarchical three-class taxonomy of study designs - experiments, quasi-experiments, and non-experiments. Based on a review of practice in three disciplines related to health systems research (epidemiology, economics, and political science), we discuss five commonly used study designs that fit our definition of quasi-experiments: natural experiments, instrumental variable analyses, regression discontinuity analyses, interrupted times series studies, and difference studies including controlled before-and-after designs, difference-in-difference designs and fixed effects analyses of panel data. We further review current practices regarding quasi-experimental studies in three non-health fields that utilize systematic reviews (education, development, and environment studies) to inform the design of approaches for synthesizing quasi-experimental evidence in health systems research. Ultimately, the aim of any review is practical: to provide useful information for policymakers, practitioners, and researchers. Future work should focus on building a consensus among users and producers of systematic reviews regarding the inclusion of quasi-experiments. Copyright © 2015 Elsevier Ireland Ltd.

Applying signal-detection theory to the study of observer accuracy and bias in behavioral assessment.

PubMed

Lerman, Dorothea C; Tetreault, Allison; Hovanetz, Alyson; Bellaci, Emily; Miller, Jonathan; Karp, Hilary; Mahmood, Angela; Strobel, Maggie; Mullen, Shelley; Keyl, Alice; Toupard, Alexis

2010-01-01

We evaluated the feasibility and utility of a laboratory model for examining observer accuracy within the framework of signal-detection theory (SDT). Sixty-one individuals collected data on aggression while viewing videotaped segments of simulated teacher-child interactions. The purpose of Experiment 1 was to determine if brief feedback and contingencies for scoring accurately would bias responding reliably. Experiment 2 focused on one variable (specificity of the operational definition) that we hypothesized might decrease the likelihood of bias. The effects of social consequences and information about expected behavior change were examined in Experiment 3. Results indicated that feedback and contingencies reliably biased responding and that the clarity of the definition only moderately affected this outcome.

High-definition television evaluation for remote handling task performance

NASA Astrophysics Data System (ADS)

Fujita, Y.; Omori, E.; Hayashi, S.; Draper, J. V.; Herndon, J. N.

Described are experiments designed to evaluate the impact of HDTV (High-Definition Television) on the performance of typical remote tasks. The experiments described in this paper compared the performance of four operators using HDTV with their performance while using other television systems. The experiments included four television systems: (1) high-definition color television, (2) high-definition monochromatic television, (3) standard-resolution monochromatic television, and (4) standard-resolution stereoscopic monochromatic television. The stereo system accomplished stereoscopy by displaying two cross-polarized images, one reflected by a half-silvered mirror and one seen through the mirror. Observers wore spectacles with cross-polarized lenses so that the left eye received only the view from the left camera and the right eye received only the view from the right camera.

Performance of gout definitions for genetic epidemiological studies: analysis of UK Biobank.

PubMed

Cadzow, Murray; Merriman, Tony R; Dalbeth, Nicola

2017-08-09

Many different combinations of available data have been used to identify gout cases in large genetic studies. The aim of this study was to determine the performance of case definitions of gout using the limited items available in multipurpose cohorts for population-based genetic studies. This research was conducted using the UK Biobank Resource. Data, including genome-wide genotypes, were available for 105,421 European participants aged 40-69 years without kidney disease. Gout definitions and combinations of these definitions were identified from previous epidemiological studies. These definitions were tested for association with 30 urate-associated single-nucleotide polymorphisms (SNPs) by logistic regression, adjusted for age, sex, waist circumference, and ratio of waist circumference to height. Heritability estimates under an additive model were generated using GCTA version 1.26.0 and PLINK version 1.90b3.32 by partitioning the genome. There were 2066 (1.96%) cases defined by self-report of gout, 1652 (1.57%) defined by urate-lowering therapy (ULT) use, 382 (0.36%) defined by hospital diagnosis, 1861 (1.76%) defined by hospital diagnosis or gout-specific medications and 2295 (2.18%) defined by self-report of gout or ULT use. Association with gout at experiment-wide significance (P < 0.0017) was observed for 13 SNPs with gout using the self-report of gout or ULT use definition, 12 SNPs using the self-report of gout definition, 11 SNPs using the hospital diagnosis or gout-specific medication definition, 10 SNPs using ULT use definition and 3 SNPs using hospital diagnosis definition. Heritability estimates ranged from 0.282 to 0.308 for all definitions except hospital diagnosis (0.236). Of the limited items available in multipurpose cohorts, the case definition of self-report of gout or ULT use has high sensitivity and precision for detecting association in genetic epidemiological studies of gout.

2018-01-01

Intercultural competence (IC) is an important skill to be gained from higher education. However, it remains unclear what IC means to students and what factors might influence their definitions of IC. The aim of the current study was to qualitatively assess how students at one higher education institution in the USA define IC and to quantitatively test for relationships among IC components and various demographic characteristics, including intercultural experience and study context. A further aim was to descriptively compare the IC definitions from the US sample with the definitions obtained from another sample of university students in Germany. A purposive sample of n = 93 undergraduate, second semester students at Dickinson College, USA, participated in the study by completing an online questionnaire. The qualitative data were content-analyzed to define the dimensions of IC. The quantitative data were cluster-analyzed to assess the multivariate relationships among the IC components and the demographic characteristics of the sample. The most important dimensions of IC were Knowledge, External Outcomes (interaction, communication), and Attitudes (respect, tolerance) according to the US sample. The most frequently chosen dimensions of IC differed between both samples: Knowledge was chosen by the sample in the USA while External Outcomes was chosen by the sample in Germany. Relative to the US sample, significantly more students chose Attitudes, External Outcomes, and Intrapersonal Skills in the sample in Germany. The relationships among IC components and demographic characteristics were only weak in the US sample. A person with IC was rated as Open-minded and Respectful by students who lived predominantly in the USA or Tolerant and Curious by those who lived outside the USA for at least six months. The current results suggest that students residing in two countries (USA or Germany) define IC using similar dimensions. However, IC definitions may depend on the intercultural experience and the current global discourse. Longitudinal studies with representative samples are required to assess how IC definitions change over time.

Effects of context on judgments concerning the reality status of novel entities.

PubMed

Woolley, Jacqueline D; Van Reet, Jennifer

2006-01-01

Three studies examined the effects of context on decisions about the reality status of novel entities. In Experiment 1 (144, 3- to 5-year-olds), participants less often claimed that novel entities were real when they were introduced in a fantastical than in a scientific context. Experiment 2 (61, 4- to 5-year-olds) revealed that defining novel entities with reference to scientific entities had a stronger effect on reality status judgments than did hearing scientifically oriented stories before encountering the novel entities. The results from Experiment 3 (192, 3- to 6-year-olds) indicated that definitions that support inferences facilitate reality status judgments more than do definitions that simply associate novel and familiar entities. These findings demonstrate that children share with adults an important means of assessing reality status.

Interpersonal and systemic aspects of emotional abuse at work: the target's perspective.

PubMed

Keashly, L

2001-06-01

The most frequent form of workplace aggression is not physical, it is emotional and psychological in nature. Known by many names, emotional abuse at work is rapidly becoming recognized as pervasive and costly both in individual and organizational terms. Most of the research to date on emotional abuse at work has utilized survey and other quantitative methodologies in an effort to document the presence, prevalence, and impact of these behaviors. However, these methodologies are based on researchers' definitions and theories of what constitutes emotional abuse rather than on the meaning given to these experiences by the targets of these behaviors. A thorough understanding of this phenomenon requires a scholarly appreciation of the target's experience. Taking "feeling abused" as the criterion variable, this study examined target's experiences based on interviews with people who self-identifed as having experienced difficulties with a boss, coworker, or subordinate. The interpersonal aspects of emotional abuse focused on the nature of behaviors exhibited and the respondents' labeling of their experience. Consistent with elements of researchers' definitions, behaviors were defined as abusive when they were repetitive, resulted in injury or harm to target, and were experienced as a lack of recognition of the individual's integrity. Judgments of violation of standards of conduct and unsolicited nature of the behaviors were also related to respondents' experiences. Relative power differential was also an important element. However, contrary to researchers' definitions, actor intent was not central in defining the experience as abusive. The systemic aspect of emotional abuse was illustrated in the nature of organizational responding to concerns raised by respondents. These responses were of critical importance in respondents' labeling of their experiences as abusive. The focus on the meaning of the behaviors for the respondents provides an enriched picture of key definitional elements. Implications of the findings for future research are discussed.

Allied health (AH) clinical education provides future health professionals with the experiences necessary to develop the healthcare competencies required for success in their individual fields. There is limited information and consensus on the purposes of clinical education, including its definition and goals, and its comprehensive role in AH clinical training. This study explored whether consensus could be achieved in the definition, goals, and factors impacting AH clinical education. An expert panel consisting of 61 AH deans (54.9% of the population) whose institutions were 2013 members of the Association of Schools of Allied Health Professions (ASAHP) participated in a three-round Delphi study. From July 2013 to March 2014, the deans expressed opinions about clinical education and its purposes. Responses were collected, summarized, and refined, and responses were accepted and re-rated until agreement was achieved or the study concluded. The hypothesis that AH deans would agree upon the definition and goals of clinical education was supported by this study's findings. Over 90% of deans "strongly agreed" or "agreed" on the definition of clinical education. A majority (90.2% to 92.7%) agreed with the goals. High agreement was achieved on the purposes of clinical education, resulting in a comprehensive definition of and goals for AH clinical education. The definition and goals of clinical education can be added in the healthcare literature and used in support of AH education.

Space Station Furnace Facility. Volume 1: Requirements definition and conceptual design study, executive summary

NASA Technical Reports Server (NTRS)

1992-01-01

The Space Station Freedom Furnace (SSFF) Study was awarded on June 2, 1989, to Teledyne Brown Engineering (TBE) to define an advanced facility for materials research in the microgravity environment of Space Station Freedom (SSF). The SSFF will be designed for research in the solidification of metals and alloys, the crystal growth of electronic and electro-optical materials, and research in glasses and ceramics. The SSFF is one of the first 'facility' class payloads planned by the Microgravity Science and Applications Division (MSAD) of the Office of Space Science and Applications of NASA Headquarters. This facility is planned for early deployment during man-tended operations of the SSF with continuing operations through the Permanently Manned Configuration (PMC). The SSFF will be built around a general 'Core' facility which provides common support functions not provided by SSF, common subsystems which are best centralized, and common subsystems which are best distributed with each experiment module. The intent of the facility approach is to reduce the overall cost associated with implementing and operating a variety of experiments. This is achieved by reducing the launch mass and simplifying the hardware development and qualification processes associated with each experiment. The Core will remain on orbit and will require only periodic maintenance and upgrading while new Furnace Modules, samples, and consumables are developed, qualified, and transported to the SSF. The SSFF Study was divided into two phases: phase 1, a definition study phase, and phase 2, a design and development phase. The definition phase 1 is addressed. Phase 1 was divided into two parts. In the first part, the basic part of the effort, covered the preliminary definition and assessment of requirements; conceptual design of the SSFF; fabrication of mockups; and the preparation for and support of the Conceptual Design Review (CoDR). The second part, the option part, covered requirements update and documentation; refinement of the selected conceptual design through additional trades and analyses; design, fabrication, and test of the Development Model; and design, fabrication, and test of the Interrack Demonstration Unit; and support of the requirements definition review (RDR). The purpose of part 2 was to prove concept feasibility.

The Meaning Of Healing: Transcending Suffering

Egnew, Thomas R.

2005-01-01

PURPOSE Medicine is traditionally considered a healing profession, but it has neither an operational definition of healing nor an explanation of its mechanisms beyond the physiological processes related to curing. The objective of this study was to determine a definition of healing that operationalizes its mechanisms and thereby identifies those repeatable actions that reliably assist physicians to promote holistic healing. METHODS This study was a qualitative inquiry consisting of in-depth, open-ended, semistructured interviews with Drs. Eric J. Cassell, Carl A. Hammerschlag, Thomas S. Inui, Elisabeth Kubler-Ross, Cicely Saunders, Bernard S. Siegel, and G. Gayle Stephens. Their perceptions regarding the definition and mechanisms of healing were subjected to grounded theory content analysis. RESULTS Healing was associated with themes of wholeness, narrative, and spirituality. Healing is an intensely personal, subjective experience involving a reconciliation of the meaning an individual ascribes to distressing events with his or her perception of wholeness as a person. CONCLUSIONS Healing may be operationally defined as the personal experience of the transcendence of suffering. Physicians can enhance their abilities as healers by recognizing, diagnosing, minimizing, and relieving suffering, as well as helping patients transcend suffering. PMID:15928230

To estimate the magnitude of access block and its trend over time in New South Wales hospitals, using different definitions of access block, and to explore its association with clinical and non-clinical factors. An epidemiological study using the Emergency Department Information System datasets (1 January 1999 to 31 December 2001) from a sample of 55 NSW hospitals. Prevalence of access block measured by four different definitions; strength of association between access block, type of hospital, year of presentation, mode and time of arrival, triage category (an indicator of urgency), age and sex. Rates of access block (for all four definitions) increased between 1999 and 2001 by 1%-2% per year. There were increases across all regions of NSW, but urban regions in particular. Patients presenting to Principal Referral hospitals and those who arrived at night were more likely to experience access block. After adjusting for triage category and year of presentation, the mode of arrival, time of arrival, type of hospital, age and sex were significantly associated with access block. Access block continues to increase across NSW, whatever the definition used. We recommend that hospitals in NSW and Australia move to the use of one standard definition of access block, as our study suggests there is no significant additional information emerging from the use of multiple definitions.

Test of the Equivalence Principle in an Einstein Elevator

NASA Technical Reports Server (NTRS)

Shapiro, Irwin I.

2002-01-01

The scientific goal of the experiment is to test the equality of gravitational and inertial mass (i.e., to test the Principle of Equivalence) by measuring the independence of the rate of fall of bodies from the composition of the falling body. The measurement is accomplished by measuring the relative displacement (or equivalently acceleration) of two falling bodies of different materials which are the proof masses of a differential accelerometer. The goal of the experiment is to measure the Eotvos ratio delta-g/g (differential acceleration/common acceleration) with an accuracy goal of a few parts in 10(exp 15). The estimated accuracy is about two orders of magnitude better than the present state of the art. The experiment is a null experiment in which a result different from zero will indicate a violation of the Equivalence Principle. The main goal of the study to be carried out under this grant is the flight definition of the experiment and bread boarding of critical components of the experiment that will enable us to be ready for the following phases of the project. The project involves an international cooperation in which the responsibility of the US side is the flight definition of the experimental facility while the responsibility of the non-US partners is the flight definition and laboratory prototyping of the differential acceleration detector. In summary, the experiment to be designed is for taking differential acceleration measurements with a high-sensitivity detector (the sensor) during free fall conditions lasting up to 30 s in a disturbance-free acceleration environment. The experiment strategy consists in letting the sensor free fall inside a few meters long (in the vertical direction) evacuated capsule that is falling simultaneously in the rarefied atmosphere after release from a helium balloon flying at a stratospheric altitude.

The Centers for Disease Control and Prevention (CDC) Division of Select Agents and Toxins (DSAT) regulates laboratories that possess, use, or transfer select agents and toxins in the United States. DSAT also mitigates biosafety risks through the review of "restricted experiments," which under the select agent regulations are experiments that pose heightened biosafety risks. From January 2006 through December 2013, DSAT received 618 requests from 109 entities to perform potentially restricted experiments. Of these requests, 85% were determined not to meet the regulatory definition of a restricted experiment, while 15% of the requests met the definition of a restricted experiment. Of the 91 restricted experiments proposed, DSAT approved 31 (34%) requests because the biosafety conditions proposed were commensurate with the experiments' biosafety risk. All 31 approved restricted experiments were for work with select toxins. DSAT did not approve 60 restricted experiment requests due to potentially serious biosafety risks to public health and safety. All 60 denied restricted experiments proposed inserting drug resistance traits into select agents that could compromise the control of disease. The select agents and toxins associated most frequently with requests that met the regulatory definition of a restricted experiment are Shiga toxin (n = 16), Burkholderia mallei (n = 15), Botulinum neurotoxin (n = 14), and Brucella abortus (n = 14). In general, all restricted experiment decisions are determined on a case-by-case basis. This article describes the trends and characteristics of the data associated with restricted experiment requests among select agents that have an impact on public health and safety (HHS only agents) or both public health and safety and animal health or products (overlap agents). The information presented here, coupled with the information published in the restricted experiment guidance document ( www.selectagents.gov ), is intended to promote awareness among the research community of the type of experiments that meet the regulatory definition of a restricted experiment as well as to provide a greater understanding of the restricted experiment review process.

Definition of intercultural competence (IC) in undergraduate students at a private university in the USA: A mixed-methods study

2018-01-01

Introduction Intercultural competence (IC) is an important skill to be gained from higher education. However, it remains unclear what IC means to students and what factors might influence their definitions of IC. The aim of the current study was to qualitatively assess how students at one higher education institution in the USA define IC and to quantitatively test for relationships among IC components and various demographic characteristics, including intercultural experience and study context. A further aim was to descriptively compare the IC definitions from the US sample with the definitions obtained from another sample of university students in Germany. Materials and methods A purposive sample of n = 93 undergraduate, second semester students at Dickinson College, USA, participated in the study by completing an online questionnaire. The qualitative data were content-analyzed to define the dimensions of IC. The quantitative data were cluster-analyzed to assess the multivariate relationships among the IC components and the demographic characteristics of the sample. Results The most important dimensions of IC were Knowledge, External Outcomes (interaction, communication), and Attitudes (respect, tolerance) according to the US sample. The most frequently chosen dimensions of IC differed between both samples: Knowledge was chosen by the sample in the USA while External Outcomes was chosen by the sample in Germany. Relative to the US sample, significantly more students chose Attitudes, External Outcomes, and Intrapersonal Skills in the sample in Germany. The relationships among IC components and demographic characteristics were only weak in the US sample. A person with IC was rated as Open-minded and Respectful by students who lived predominantly in the USA or Tolerant and Curious by those who lived outside the USA for at least six months. Discussion The current results suggest that students residing in two countries (USA or Germany) define IC using similar dimensions. However, IC definitions may depend on the intercultural experience and the current global discourse. Longitudinal studies with representative samples are required to assess how IC definitions change over time. PMID:29698525

Sodium-sulfur battery flight experiment definition study

NASA Technical Reports Server (NTRS)

Chang, Rebecca; Minck, Robert

1990-01-01

Sodium-sulfur batteries are considered to be one of the most likely battery systems for space applications. Compared with the Ni-H2 or Ni-Co battery systems, Na-S batteries offer a mass reduction by a factor of 2 to 4, representing significant launch cost savings or increased payload mass capabilities. The Na-S battery operates at between 300 and 400 C, using liquid sodium and sulfur/polysulfide electrodes and solid ceramic electrolyte; the transport of the electrode materials to the surface of the electrolyte is through wicking/capillary forces. This paper describes five tests identified for the Na-S battery flight experiment definition study, which include the cell characterization test, the reactant distribution test, the current/temperature distribution test, the freeze/thaw test, and the multicell LEO test. A schematic diagram of Na-S cell is included.

The missing link? Testing a schema account of unitization.

PubMed

Tibon, Roni; Greve, Andrea; Henson, Richard

2018-05-09

Unitization refers to the creation of a new unit from previously distinct items. The concept of unitization has been used to explain how novel pairings between items can be remembered without requiring recollection, by virtue of new, item-like representations that enable familiarity-based retrieval. We tested an alternative account of unitization - a schema account - which suggests that associations between items can be rapidly assimilated into a schema. We used a common operationalization of "unitization" as the difference between two unrelated words being linked by a definition, relative to two words being linked by a sentence, during an initial study phase. During the following relearning phase, a studied word was re-paired with a new word, either related or unrelated to the original associate from study. In a final test phase, memory for the relearned associations was tested. We hypothesized that, if unitized representations act like schemas, then we would observe some generalization to related words, such that memory would be better in the definition than sentence condition for related words, but not for unrelated words. Contrary to the schema hypothesis, evidence favored the null hypothesis of no difference between definition and sentence conditions for related words (Experiment 1), even when each cue was associated with multiple associates, indicating that the associations can be generalized (Experiment 2), or when the schematic information was explicitly re-activated during Relearning (Experiment 3). These results suggest that unitized associations do not generalize to accommodate new information, and therefore provide evidence against the schema account.

Professionalism: A Core Competency, but What Does it Mean? A Survey of Surgery Residents.

PubMed

Dilday, Joshua C; Miller, Elizabeth A; Schmitt, Kyle; Davis, Brian; Davis, Kurt G

2017-10-27

Professionalism is 1 of the 6 core competencies of the Accreditation Council of Graduate Medical Education. Despite its obvious importance, it is poorly defined in the literature and an understanding of its meaning has not been evaluated on surgical trainees. The American College of Surgeons (ACS) has previously published tenets of surgical professionalism. However, surgery residents may not share similar views on professionalism as those of the ACS. Surgical residents of all levels at 2 surgery residencies located in the same city were interviewed regarding their personal definitions, thoughts, and experiences regarding professionalism during their training. They were then queried regarding 20 points of professionalism as outlined by the ACS tenets of professionalism. The study utilized the surgery residencies at William Beaumont Army Medical Center and Texas Tech University Health Science Center in El Paso, Texas. All general surgery residents at each program were invited to participate in the study. Eighteen residents volunteered to take the survey and be interviewed. The definitions of professionalism centered on clinical competence. Surgery residents conveyed experiences with both professional and unprofessional behavior. Seven of the 20 ACS tenets of professionalism were unanimously agreed upon. There were key differences between resident definitions and those as outlined by the ACS. The least agreed upon ACS tenets of professionalism include professionalism education, public education, and public health. Surgical trainees express personal experiences in both professional and unprofessional behavior. Their definitions of professionalism are not as expansive as those of the ACS and seem to focus on patient and colleague interaction. Due to the lack of congruency, a tailored curriculum for professionalism based upon ACS tenets appears warranted. Published by Elsevier Inc.

2007-01-01

Objective To summarize findings from a systematic exploration of existing literature and views regarding interdisciplinarity, to discuss themes and components of such work, and to propose a theoretically based definition of interdisciplinary research. Data Sources/Study Setting Two major data sources were used: interviews with researchers from various disciplines, and a systematic review of the education, business, and health care literature from January 1980 through January 2005. Study Design Systematic review of literature, one-on-one interviews, field test (survey). Data Collection/Extraction Methods We reviewed 14 definitions of interdisciplinarity, the characteristics of 42 interdisciplinary research publications from multiple fields of study, and 14 researcher interviews to arrive at a preliminary definition of interdisciplinary research. That definition was then field tested by 12 individuals with interdisciplinary research experience, and their responses incorporated into the definition of interdisciplinary research proposed in this paper. Principal Findings Three key definitional characteristics were identified: the qualitative mode of research (and its theoretical underpinnings), existence of a continuum of synthesis among disciplines, and the desired outcome of the interdisciplinary research. Conclusion Existing literature from several fields did not provide a definition for interdisciplinary research of sufficient specificity to facilitate activities such as identification of the competencies, structure, and resources needed for health care and health policy research. This analysis led to the proposed definition, which is designed to aid decision makers in funding agencies/program committees and researchers to identify and take full advantage the interdisciplinary approach, and to serve as a basis for competency-based formalized training to provide researchers with interdisciplinary skills.

Learning terms and definitions: Drawing and the role of elaborative encoding.

PubMed

Wammes, Jeffrey D; Meade, Melissa E; Fernandes, Myra A

2017-09-01

Traditionally, students adopt the strategy of taking written notes when attending a class or learning from a textbook in educational settings. Informed by previous work showing that learning by doing improves memory performance, we examined whether drawing to-be-remembered definitions from university textbooks would improve later memory, relative to a more typical strategy of rote transcription. Participants were asked to either write out the definition, or to draw a picture representative of the definition. Results indicated that drawing, relative to verbatim writing, conferred a reliable memorial benefit that was robust, even when participants' preexisting familiarity with the terms was included as a covariate (in Experiment 1) or when the to-be-remembered terms and definitions were fictitious, thus removing the influence of familiarity (in Experiment 2). We reasoned that drawing likely facilitates retention at least in part because at encoding, participants must retain and elaborate upon information regarding the meaning of the definition, to translate it into a new form (a picture). This is not the case when participants write out the definitions verbatim. In Experiment 3 we showed that paraphrasing during encoding, which, like drawing and in contrast with verbatim writing, requires self-generated elaboration, led to memory performance that was comparable to drawing. Taken together, results suggest that drawing is a powerful tool which improves memory, and that drawing produces a similar level of retention as does paraphrasing. This suggests that elaborative encoding plays a critical role in the memorial benefit that drawing confers to memory for definitions of academic terms. Copyright © 2017 Elsevier B.V.

Assessing Adult Exposure to Community Violence: A Review of Definitions and Measures.

PubMed

DeCou, Christopher R; Lynch, Shannon M

2017-01-01

Although experiences of community violence are linked with negative outcomes for adults and children, few standardized measures assessing community violence exist, and available measures lack consistency concerning the definition of community violence. Further, most measures currently utilized to assess adult exposure to community violence were designed for use with children and adolescents. To address these identified concerns and make recommendations for future research, this article reviews contemporary definitions of community violence, identifies the outcomes of exposure to community violence for adults, and evaluates measures of exposure to community violence with published psychometric data employing adult samples. A systematic review of the literature was conducted to identify studies that (1) included a self-report of community violence exposure, (2) included primarily adult respondents, and (3) reported psychometric data. Seventeen studies met the inclusion criteria. Measures employed in these studies were reviewed and basic psychometric properties discussed. Notably, the Survey of Exposure to Community Violence was the most commonly used measure among these studies. Although multiple measures demonstrated limited but acceptable psychometric performance in select studies, few in-depth psychometric analyses exist for measures of adult exposure to community violence. Also, it is difficult to compare studies due to variations in definitions of community violence and multiple versions of each measure. Recommendations for future research include provision of explicit definitions of community violence and reporting psychometric data for measures. © The Author(s) 2015.

Developing the Cyber Victimization Experiences and Cyberbullying Behaviors Scales.

PubMed

Betts, Lucy R; Spenser, Karin A

2017-01-01

The reported prevalence rates of cyber victimization experiences and cyberbullying behaviors vary. Part of this variation is likely due to the diverse definitions and operationalizations of the constructs adopted in previous research and the lack of psychometrically robust measures. Through 2 studies, the authors developed (Study 1) and evaluated (Study 2) the cyber victimization experiences and cyberbullying behaviors scales. Participants in Study 1 were 393 (122 boys, 171 girls) and in Study 2 were 345 (153 boys, 192 girls) 11-15-year-olds who completed measures of cyber victimization experiences, cyberbullying behaviors, face-to-face victimization experiences, face-to-face bullying behaviors, and social desirability. The 3-factor cyber victimization experiences scale comprised threat, shared images, and personal attack. The 3-factor cyberbullying behaviors scale comprised sharing images, gossip, and personal attack. Both scales demonstrated acceptable internal consistency and convergent validity.

Methods Two split-form surveys were conducted online among 6–17 year olds (n=1,200 each) to inform recommendations for cyberbullying measurement. Results Measures that use the word ‘bully’ result in prevalence rates similar to each other whether or not a definition is included, whereas measures not using the word ‘bully’ are similar to each other whether or not a definition is included. A behavioral list of bullying experiences without either a definition or the word ‘bully’ results in higher prevalence rates and likely measures experiences that are beyond the definition of ‘bullying’. Follow-up questions querying differential power, repetition, and bullying over time were used to examine misclassification. The measure using a definition but not the word ‘bully’ appeared to have the highest rate of false positives and, therefore, the highest rate of misclassification. Across two studies, an average of 25% reported being bullied at least monthly in person compared with an average of 10% bullied online, 7% via telephone (cell or landline), and 8% via text messaging. Conclusions Measures of bullying among English-speaking samples in the US should include the word ‘bully’ when possible. The definition may be a useful tool for researchers, but results suggest that it does not necessarily yield a more rigorous measure of bullying victimization. Directly measuring aspects of bullying (i.e., differential power, repetition, over time) reduces misclassification. To prevent double counting across categories, we conceptualize cyberbullying as bullying communicated through the online mode; type (e.g., verbal, relational), and environment (e.g., school, home) are additional domains of bullying.

Shuttle free-flying teleoperator system experiment definition. Volume 3: program development requirements

NASA Technical Reports Server (NTRS)

1972-01-01

The planning data are presented for subsequent phases of free-flying teleoperator program (FFTO) and includes costs, schedules and supporting research and technology activities required to implement the free-flying teleoperator system and associated flight equipment. The purpose of the data presented is to provide NASA with the information needed to continue development of the FFTO and integrate it into the space shuttle program. The planning data describes three major program phases consisting of activities and events scheduled to effect integrated design, development, fabrication and operation of an FFTO system. Phase A, Concept Generation, represents a study effort directed toward generating and evaluating a number of feasible FFTO experiment system concepts. Phase B, Definition, will include preliminary design and supporting analysis of the FFTO, the shuttle based equipment and ground support equipment. Phase C/D, Design, Development and Operations will include detail design of the operational FFTO, its integration into the space shuttle, hardware fabrication and testing, delivery of flight hardware and support of flight operations. Emphasis is placed on the planning for Phases A and B since these studies will be implemented early in the development cycle. Phase C/D planning is more general and subject to refinement during the definition phase.

Women continue to be underrepresented in the fields of science, technology, engineering, and mathematics (STEM). One factor contributing to this underrepresentation is the graduate school experience. Graduate programs in STEM fields are constructed around assumptions that ignore the reality of women's lives; however, emerging opportunities may lead to experiences that are more compatible for women. One such opportunity is the Graduate Teaching Fellows in K-12 Education (GK-12) Program, which was introduced by the National Science Foundation in 1999. Although this nontraditional graduate program was not designed explicitly for women, it provided an unprecedented context in which to research how changing some of the basic assumptions upon which a graduate school operates may impact women in science. This exploratory case study examines the self-definition of 8 women graduate students who participated in a GK-12 program at a major research university. The findings from this case study contribute to higher education's understanding of the terrain women graduate students in the STEM areas must navigate as they participate in programs that are thought to be more conducive to their modes of self-definition while they continue to seek to be successful in the historically Eurocentric, masculine STEM fields.

2015-07-01

The prevalence of constipation among patients in palliative care has varied in prior research, from 18% to 90%, depending on study factors. The aim of this study was to describe and explore the prevalence and symptom distress of constipation, using different definitions of constipation, in patients admitted to specialized palliative care settings. Data was collected in a cross-sectional survey from 485 patients in 38 palliative care units in Sweden. Variables were analyzed using logistic regression and summarized as odds ratio (OR). The prevalence of constipation varied between 7% and 43%, depending on the definition used. Two constipation groups were found: (1) medical constipation group (MCG): ≤3 defecations/week, n=114 (23%) and (2) perceived constipation group (PCG): patients with a perception of being constipated in the last two weeks, n=171 (35%). Three subgroups emerged: patients with (1) only medical constipation (7%), (2) only perceived constipation (19%), and (3) both medical and perceived constipation (16%). There were no differences in symptom severity between groups; 71% of all constipated patients had severe constipation. The prevalence of constipation may differ, depending on the definition used and how constipation is assessed. In this study we found two main groups and three subgroups, analyzed from the definitions of frequency of bowel movements and experience of being constipated. To be able to identify constipation, the patients' definition has to be further explored and assessed.

Parang, M.; Crocker, D. S.

1991-01-01

The definition phase of an in-space experiment in thermoacoustic convection (TAC) heat transfer phenomenon is completed and the results are presented and discussed in some detail. Background information, application and potential importance of TAC in heat transfer processes are discussed with particular focus on application in cryogenic fluid handling and storage in microgravity space environment. Also included are the discussion on TAC space experiment objectives, results of ground support experiments, hardware information, and technical specifications and drawings. The future plans and a schedule for the development of experiment hardware (Phase 1) and flight tests and post-flight analysis (Phase 3/4) are also presented. The specific experimental objectives are rapid heating of a compressible fluid and the measurement of the fluid temperature and pressure and the recording and analysis of the experimental data for the establishment of the importance of TAC heat transfer process. The ground experiments that were completed in support of the experiment definition included fluid temperature measurement by a modified shadowgraph method, surface temperature measurements by thermocouples, and fluid pressure measurements by strain-gage pressure transducers. These experiments verified the feasibility of the TAC in-space experiment, established the relevance and accuracy of the experimental results, and specified the nature of the analysis which will be carried out in the post-flight phase of the report.

Flexibility of Event Boundaries in Autobiographical Memory

PubMed Central

Hohman, Timothy J.; Peynircioğlu, Zehra F.; Beason-Held, Lori L.

2014-01-01

Events have clear and consistent boundaries that are defined during perception in a manner that influences memory performance. The natural process of event segmentation shapes event definitions during perception, and appears to play a critical role in defining distinct episodic memories at encoding. However, the role of retrieval processes in modifying event definitions is not clear. We explored how such processes changed event boundary definitions at recall. In Experiment 1 we showed that distance from encoding is related to boundary flexibility. Participants were more likely to move self-reported event boundaries to include information reported beyond those boundaries when recalling more distant events compared to more recent events. In Experiment 2, we showed that age also influenced boundary flexibility. Older Age adults were more likely to move event boundaries than College Age adults, and the relationship between distance from encoding and boundary flexibility seen in Experiment 1 was present only in College Age and Middle Age adults. These results suggest that factors at retrieval have a direct impact on event definitions in memory and that, although episodic memories may be initially defined at encoding, these definitions are not necessarily maintained in long-term memory.

There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis.

A super-cooled magnetic spectrometer for a cosmic-ray experiment is considered for application in the high energy astronomical observatory which may be used on a space shuttle spacelab mission. New cryostat parameters are reported which are appropriate to shuttle mission weight and mission duration constraints. Since a super-conducting magnetic spectrometer has a magnetic fringe field, methods for shielding sensitive electronic and mechanical components on nearby experiments are described.

4K x 2K pixel color video pickup system

1998-12-01

This paper describes the development of an experimental super- high-definition color video camera system. During the past several years there has been much interest in super-high- definition images as the next generation image media. One of the difficulties in implementing a super-high-definition motion imaging system is constructing the image-capturing section (camera). Even the state-of-the-art semiconductor technology can not realize the image sensor which has enough pixels and output data rate for super-high-definition images. The present study is an attempt to fill the gap in this respect. The authors intend to solve the problem by using new imaging method in which four HDTV sensors are attached on a new color separation optics so that their pixel sample pattern forms checkerboard pattern. A series of imaging experiments demonstrate that this technique is an effective approach to capturing super-high-definition moving images in the present situation where no image sensors exist for such images.

Russell, Richard A.; Waiss, Richard D.

1988-01-01

A study was conducted to identify the common support equipment and Space Station interface requirements for the IOC (initial operating capabilities) model technology experiments. In particular, each principal investigator for the proposed model technology experiment was contacted and visited for technical understanding and support for the generation of the detailed technical backup data required for completion of this study. Based on the data generated, a strong case can be made for a dedicated technology experiment command and control work station consisting of a command keyboard, cathode ray tube, data processing and storage, and an alert/annunciator panel located in the pressurized laboratory.

2013-01-01

As part of the research relating personality and depression, this study seeks to predict depressive experiences in aging women according to Sidney Blatt's perspective based on the Five-Factor Model of Personality. The NEO-Five Factor Inventory and the Depressive Experiences Questionnaire were administered. The domains Neuroticism, Agreeableness, and Conscientiousness predicted self-criticism, explaining 68% of the variance; the domains Neuroticism and Extraversion predicted dependency, explaining 62% of the variance. The subfactors Neediness and Connectedness were differently related to personality traits. These findings are relevant to the research relating personality and anaclitic / introjective depressive experiences in late adulthood.

Definitions of love in a sample of British women: an empirical study using Q methodology.

PubMed

Watts, Simon; Stenner, Paul

2014-09-01

Social psychological research has increasingly acknowledged that any pretensions to a singular theory of love should be replaced with a concern about its affirmation and what people actually say and do in love's name. Lee's (1977) love styles research and Sternberg's (1995) theory of love as a story are prime examples. Despite traditional definitions of love in western cultures being dominated by feminine images and tales of gender difference, however, the personal definitions and experiences of women have received comparatively little empirical attention, particularly in recent years and despite some well-documented changes in their cultural circumstances. This study remedies that situation through presentation of a Q methodological study in which a convenience sample of 59 British women were asked to Q sort 54 single-word descriptors of love to define love as they had experienced it. Factor analysis of the resulting Q sorts revealed six distinct definitions of love, interpreted as 'attraction, passion & romance', 'unconditional love', 'sex & fun', 'friendship & spirituality', 'a permanent commitment', and 'separate people, separate lives'. The six definitions are then discussed in terms of their allegiance to traditionally feminine and/or masculine values and as a means of highlighting the changing face of Britain's relational culture. © 2013 The British Psychological Society.

Review of Restricted Experiment Requests, Division of Select Agents and Toxins, Centers for Disease Control and Prevention, 2006-2013

PubMed Central

Smith, Jacinta; Weyant, Robbin

2015-01-01

The Centers for Disease Control and Prevention (CDC) Division of Select Agents and Toxins (DSAT) regulates laboratories that possess, use, or transfer select agents and toxins in the United States. DSAT also mitigates biosafety risks through the review of “restricted experiments,” which under the select agent regulations are experiments that pose heightened biosafety risks. From January 2006 through December 2013, DSAT received 618 requests from 109 entities to perform potentially restricted experiments. Of these requests, 85% were determined not to meet the regulatory definition of a restricted experiment, while 15% of the requests met the definition of a restricted experiment. Of the 91 restricted experiments proposed, DSAT approved 31 (34%) requests because the biosafety conditions proposed were commensurate with the experiments' biosafety risk. All 31 approved restricted experiments were for work with select toxins. DSAT did not approve 60 restricted experiment requests due to potentially serious biosafety risks to public health and safety. All 60 denied restricted experiments proposed inserting drug resistance traits into select agents that could compromise the control of disease. The select agents and toxins associated most frequently with requests that met the regulatory definition of a restricted experiment are Shiga toxin (n = 16), Burkholderia mallei (n = 15), Botulinum neurotoxin (n = 14), and Brucella abortus (n = 14). In general, all restricted experiment decisions are determined on a case-by-case basis. This article describes the trends and characteristics of the data associated with restricted experiment requests among select agents that have an impact on public health and safety (HHS only agents) or both public health and safety and animal health or products (overlap agents). The information presented here, coupled with the information published in the restricted experiment guidance document (www.selectagents.gov), is intended to promote awareness among the research community of the type of experiments that meet the regulatory definition of a restricted experiment as well as to provide a greater understanding of the restricted experiment review process.

Constructing normality: a discourse analysis of the DSM-IV.

PubMed

Crowe, M

2000-01-01

The purpose of this research was to explore how the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) 1994, (American Psychiatric Association, 1994) defines mental disorder and the theoretical assumptions upon which this is based. The analysis examines how the current definition has been constructed and what the criteria for specific mental disorders suggest about what is regarded as normal. The method employed for the research was a critical discourse analysis. This critical approach to research is primarily concerned with analysis of the use of language and the reproduction of dominant belief systems in discourse. It involves systematic and repeated readings of the DSM-IV (1994) to examine what evidence was employed by the text to substantiate its definition of mental disorder and how in the process some assumptions are made about what constitutes normality. This study challenges a central assumption in the DSM-IV's (1994) definition: that it is a pattern or syndrome 'that occurs in an individual'. The proposal that it occurs in an individual implies that it is a consequence of faulty individual functioning. This effectively excludes the social and cultural context in which experiences occur and ignores the role of discourse in shaping subjectivity and social relations. This study proposes that the definition and criteria for mental disorder are based on assumptions about normal behaviour that relate to productivity, unity, moderation and rationality. The influence of this authoritative image of normality pervades many areas of social life and pathologies experiences that could be regarded as responses to life events.

Test of the Equivalence Principle in an Einstein Elevator

Shapiro, Irwin I.; Glashow, S.; Lorenzini, E. C.; Cosmo, M. L.; Cheimets, P.; Finkelstein, N.; Schneps, M.

2004-01-01

The scientific goal of the experiment is to test the equality of gravitational and inertial mass (i.e., to test the Principle of Equivalence) by measuring the independence of the rate of fall of bodies from the composition of the falling body. The measurement is accomplished by measuring the relative displacement (or equivalently acceleration) of two falling bodies of different materials which are the proof masses of a differential accelerometer. The goal of the experiment is to measure the Eoetvoes ratio sigma g/g (differential acceleration/common acceleration) with an accuracy goal of several parts in 10(exp 15). The estimated accuracy is about two orders of magnitude better than the present state of the art. The main goal of the study to be carried out under this grant is part of the flight definition of the experiment and laboratory testing of key components. The project involves an international cooperation in which the responsibility of the US side is the flight definition of the experimental facility while the responsibility of the non-US partners is the flight definition and laboratory prototyping of the differential acceleration detector.In summary, the experiment to be designed is for taking differential acceleration measurements with a high-sensitivity detector (the sensor) during free fall conditions lasting up to 30 s in a disturbance-free acceleration environment. The experiment strategy consists in letting the sensor free fall inside a few meters long (in the vertical direction) evacuated capsule that is falling simultaneously in the rarefied atmosphere after release from a helium balloon flying at a stratospheric altitude.

Grounding Abstractness: Abstract Concepts and the Activation of the Mouth

PubMed Central

Borghi, Anna M.; Zarcone, Edoardo

2016-01-01

One key issue for theories of cognition is how abstract concepts, such as freedom, are represented. According to the WAT (Words As social Tools) proposal, abstract concepts activate both sensorimotor and linguistic/social information, and their acquisition modality involves the linguistic experience more than the acquisition of concrete concepts. We report an experiment in which participants were presented with abstract and concrete definitions followed by concrete and abstract target-words. When the definition and the word matched, participants were required to press a key, either with the hand or with the mouth. Response times and accuracy were recorded. As predicted, we found that abstract definitions and abstract words yielded slower responses and more errors compared to concrete definitions and concrete words. More crucially, there was an interaction between the target-words and the effector used to respond (hand, mouth). While responses with the mouth were overall slower, the advantage of the hand over the mouth responses was more marked with concrete than with abstract concepts. The results are in keeping with grounded and embodied theories of cognition and support the WAT proposal, according to which abstract concepts evoke linguistic-social information, hence activate the mouth. The mechanisms underlying the mouth activation with abstract concepts (re-enactment of acquisition experience, or re-explanation of the word meaning, possibly through inner talk) are discussed. To our knowledge this is the first behavioral study demonstrating with real words that the advantage of the hand over the mouth is more marked with concrete than with abstract concepts, likely because of the activation of linguistic information with abstract concepts.

Understanding and defining bullying - adolescents' own views.

The negative consequences of peer-victimization on children and adolescents are major public health concerns which have been subjected to extensive research. Given all efforts made to analyze and estimate the social and health consequences of peer-victimization, the adolescents' own experiences and understandings have had surprisingly little impact on the definition of bullying. Therefore, the aim of the current study is to explore adolescents' definitions of bullying. A questionnaire study (n = 128) and four focus group interviews (n = 21) were conducted among students aged 13 and 15. First, gender and age differences were analyzed with respect to what behaviors are considered bullying (questionnaire data). Second, analysis of what bullying is (focus group interviews) was conducted using qualitative content analysis. The adolescents own understanding and definition of bullying didn't just include the traditional criteria of repetition and power imbalance, but also a criterion based on the health consequences of bullying. The results showed that a single but hurtful or harmful incident also could be considered bullying irrespective of whether the traditional criteria were fulfilled or not. Further, girls and older students had a more inclusive view of bullying and reported more types of behaviors as bullying compared to boys and younger students. The results of the current study adds to the existing literature by showing that adolescents consider the victim's experience of hurt and harm as a criterion for defining bullying and not only as consequences of bullying. This may be of special relevance for the identification and classification of bullying incidents on the internet where devastating consequences have been reported from single incidents and the use of the traditional criteria of intent, repetition and power imbalance may not be as relevant as for traditional bullying. It implies that the traditional criteria included in most definitions of bullying may not fully reflect adolescents' understanding and definition of bullying. Assessments of bullying behaviors that ask adolescents to strictly adhere to the traditional definition of bullying might not identify all adolescents experiencing peer victimization and therefore not provide estimates of prevalence rates reflecting adolescents' own understanding of bullying.

Understanding Children and Adolescents’ Victimizations at Multiple Levels: An Ecological Review of the Literature

This article examines children and adolescent exposure to violence in various contexts. A systematic review of the literature was conducted to identify the definitions and types of violence reported in studies on victimization using the ecological systems framework. Sources included research studies and/or reports from scholarly journals (n = 140), books (n = 9), conference/workshops (n = 5), and web sources, such as Uniform Crime Reports (n = 23). The findings indicated that research differed in terminologies, conceptual and operational definitions, sample sizes and age group classification for children and adolescents. Further, studies lacked focus on the co-occurrence and inter-relatedness of victimization, and how these factors might affect the outcomes. Many studies employed a cross-sectional design, which limits strong conclusions about the temporal order of victimization experiences and outcomes. Future research efforts need more consistency among researchers in conceptual and operational definitions and the use of more rigorous designs. Increased holistic assessments are critical for effective prevention and intervention strategies for at-risk children and adolescents PMID:24065867

Defining and measuring cyberbullying within the larger context of bullying victimization.

To inform the scientific debate about bullying, including cyberbullying, measurement. Two split-form surveys were conducted online among 6-17-year-olds (n = 1,200 each) to inform recommendations for cyberbullying measurement. Measures that use the word "bully" result in prevalence rates similar to each other, irrespective of whether a definition is included, whereas measures not using the word "bully" are similar to each other, irrespective of whether a definition is included. A behavioral list of bullying experiences without either a definition or the word "bully" results in higher prevalence rates and likely measures experiences that are beyond the definition of "bullying." Follow-up questions querying differential power, repetition, and bullying over time were used to examine misclassification. The measure using a definition but not the word "bully" appeared to have the highest rate of false positives and, therefore, the highest rate of misclassification. Across two studies, an average of 25% reported being bullied at least monthly in person compared with an average of 10% bullied online, 7% via telephone (cell or landline), and 8% via text messaging. Measures of bullying among English-speaking individuals in the United States should include the word "bully" when possible. The definition may be a useful tool for researchers, but results suggest that it does not necessarily yield a more rigorous measure of bullying victimization. Directly measuring aspects of bullying (i.e., differential power, repetition, over time) reduces misclassification. To prevent double counting across domains, we suggest the following distinctions: mode (e.g., online, in-person), type (e.g., verbal, relational), and environment (e.g., school, home). We conceptualize cyberbullying as bullying communicated through the online mode. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Instability in Thoracolumbar Trauma: Is a New Definition Warranted?

Review of the articles. The objective of this study was to review all articles related to spinal instability to determine a consensus statement for a contemporary, practical definition applicable to thoracolumbar injuries. Traumatic fractures of the thoracolumbar spine are common. These injuries can result in neurological deficits, disability, deformity, pain, and represent a great economic burden to society. The determination of spinal instability is an important task for spine surgeons, as treatment strategies rely heavily on this assessment. However, a clinically applicable definition of spinal stability remains elusive. A review of the Medline database between 1930 and 2014 was performed limited to papers in English. Spinal instability, thoracolumbar, and spinal stability were used as search terms. Case reports were excluded. We reviewed listed references from pertinent search results and located relevant manuscripts from these lists as well. The search produced a total of 694 published articles. Twenty-five articles were eligible after abstract screening and underwent full review. A definition for spinal instability was described in only 4 of them. Definitions were primarily based on biomechanical and classification studies. No definitive parameters were outlined to define stability. Thirty-six years after White and Panjabi's original definition of instability, and many classification schemes later, there remains no practical and meaningful definition for spinal instability in thoracolumbar trauma. Surgeon expertise and experience remains an important factor in stability determination. We propose that, at an initial assessment, a distinction should be made between immediate and delayed instability. This designation should better guide surgeons in decision making and patient counseling.

Considering lesbian identity from a social-psychological perspective: two different models of "being a lesbian".

PubMed

Tate, Charlotte Chuck

2012-01-01

One long-standing project within lesbian studies has been to develop a satisfactory working definition of "lesbian." This article proposes two new models of a definition using principles of social psychology. Each model (a) utilizes the premise that gender lacks a categorical essence and (b) separates behavioral adherence to cultural stereotypes of femininity and masculinity from one's gender self-categorization. From these premises, I generate and critique two internally coherent models of lesbian identity that are inclusive (to different degrees) of various gender identities. For each model, the potential inclusion of trans men, trans women, genderqueers, and lesbian-identified cisgender men is evaluated. The explanatory power of these models is twofold. One, the models can serve as theoretical perspectives for scholars who study the intersection of gender and sexual identity. Two, the models can also characterize the everyday experience of people who have tacit working definitions of lesbian identity.

Transcatheter aortic valve replacement (TAVR) requires large calibre catheters and is therefore associated with increased vascular complications. The aim of this study was to illustrate the impact of the different definitions of major vascular complications on their incidence and to underscore the importance of uniform reporting. We pooled dedicated databases of consecutive patients undergoing TAVR from two tertiary care facilities and looked for the incidence of major vascular complications using various previously reported definitions. The level of agreement (Kappa statistic) between the respective definitions and the Valve Academic Research Consortium (VARC) consensus definition of vascular complications was assessed. A total of 345 consecutive patients underwent transfemoral TAVR and were included in this analysis. A completely percutaneous access and closure technique was applied in 96% of cases. Arterial sheath size ranged between 18 and 24 Fr, the majority being 18 Fr (60%). Procedural success was reached in 94.5%. Depending on the definition used, major vascular complications occurred in 5.2-15.9% of patients. According to the VARC definitions, the rate of major and minor vascular complications was 9.0% and 9.6%, respectively. Major vascular complications according to VARC criteria demonstrated at least a substantial level of agreement with the SOURCE registry (k 0.80), the UK registry (k 0.82) the Italian registry (k 0.72) and "FRANCE" registry (k 0.70) definitions, compared to a moderate level of agreement with the definitions used in the German registry ( 0.47) and the 18 Fr Safety and Efficacy study (k 0.42). Minor complications according to VARC demonstrated a moderate agreement only with vascular complications using the German registry definition (k 0.54). Non-uniformity in how vascular complications are defined precludes any reliable comparison between previously reported TAVR registries. The VARC consensus document offers standardised endpoint definitions and should be universally adopted to obtain better insights into global TAVR experience.

Having defined the distinction between hypnagogic imagery and dreams, a preliminary study on the individual differences in the experience of visual hypnagogic imagery was conducted. (1) A questionnaire on visual hypnagogic experience was administered to 796 students. The results suggested that previous researches on the incidence of this experience might have suffered from ambiguous definitions. (2) The Scale of Mental Imagery (Hasegawa, 1992) was administered to 330 of the same students, Eysenck Personality Questionnaire to 305 students, and S-A Creativity Test (Sozosei-shinri-kenkyukai, 1969) to 221 students. The frequency of hypnagogic experiences was significantly associated with the scores of "the vividness of mental imagery", "neuroticism", and "creativity". (3) Based on these results, a proposed research problem on hypnagogic imagery was discussed.

The purpose of this study was to present our experience utilizing cetuximab and platinum-based concurrent chemoradiotherapy for the definitive treatment of head and neck squamous cell carcinoma (HNSCC). Patients (n = 177) who received definitive concurrent chemoradiotherapy for HNSCC were stratified into 3 groups: receiving cetuximab monotherapy (n = 24), cetuximab and chemotherapy combination (n = 33), or platinum-based chemotherapy without cetuximab (n = 120). Primary endpoints were freedom from relapse, event-free survival, and overall survival (OS). Patients receiving cetuximab monotherapy were older with lower Karnofsky performance status (KPS) and higher Charlson comorbidity scores compared with those treated with combination cetuximab and chemotherapy or platinum-based concurrent chemoradiotherapy. Patients treated with platinum-based concurrent chemoradiotherapy exhibited significantly better freedom from relapse, event-free survival, and OS compared with those receiving cetuximab monotherapy or cetuximab and chemotherapy combination therapies (all p < .05). Differences between patients receiving cetuximab monotherapy and platinum-based concurrent chemoradiotherapy held on multivariate Cox regression. This study suggests that platinum-based concurrent chemoradiotherapy is superior to cetuximab-based monotherapy for the definitive treatment of HNSCC. © 2014 Wiley Periodicals, Inc.

Seizure clusters: characteristics and treatment.

PubMed

Haut, Sheryl R

2015-04-01

Many patients with epilepsy experience 'clusters' or flurries of seizures, also termed acute repetitive seizures (ARS). Seizure clustering has a significant impact on health and quality of life. This review summarizes recent advances in the definition and neurophysiologic understanding of clustering, the epidemiology and risk factors for clustering and both inpatient and outpatient clinical implications. New treatments for seizure clustering/ARS are perhaps the area of greatest recent progress. Efforts have focused on creating a uniform definition of a seizure cluster. In neurophysiologic studies of refractory epilepsy, seizures within a cluster appear to be self-triggering. Clinical progress has been achieved towards a more precise prevalence of clustering, and consensus guidelines for epilepsy monitoring unit safety. The greatest recent advances are in the study of nonintravenous route of benzodiazepines as rescue medications for seizure clusters/ARS. Rectal benzodiazepines have been very effective but barriers to use exist. New data on buccal, intramuscular and intranasal preparations are anticipated to lead to a greater number of approved treatments. Progesterone may be effective for women who experience catamenial clusters. Seizure clustering is common, particularly in the setting of medically refractory epilepsy. Clustering worsens health and quality of life, and the field requires greater focus on clarifying of definition and clinical implications. Progress towards the development of nonintravenous routes of benzodiazepines has the potential to improve care in this area.

There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis. PMID:22448023

Widespread pain: is an improved classification possible?

PubMed

MacFarlane, G J; Croft, P R; Schollum, J; Silman, A J

1996-09-01

The classification of widespread pain, proposed by the American College of Rheumatology (ACR) for use in the clinic as a screen for fibromyalgia, as described, does not require truly widespread pain. Studies considering the epidemiology of widespread pain per se may therefore require a definition with greater face validity, which might also show enhanced associations with other physical and psychological measures. We aimed to develop a more coherent definition of widespread pain for use in epidemiological studies and to compare performance in identifying individuals with significant morbidity. A group of 172 subjects who had participated in a community based study on the occurrence of pain were identified and categorized by their pain experience as indicated on line drawings of the body according to ACR definition and to a new, more stringent definition that required the presence of more diffuse limb pain. A number of other clinical and psychological measures were recorded for these individuals and the association between their pain status measures and these other variables was assessed and compared. Persons satisfying the newly proposed definition for chronic widespread pain, in comparison with those who satisfied only the present ACR definition, had a significantly higher score on the General Health Questionnaire [median difference (MD) 7.95% CI 1.13], a higher score on the Health and Fatigue Questionnaire (MD 10.95% CI 0.15), and greater problems with sleep (sleep problem score MD 4.95% CI 0.9). Those satisfying the new definition also had a greater number of tender points on examination (MD 3.95% CI -1.7). The morbidity of those satisfying only the present ACR definition was closer to persons who had regional pain. A redefinition of widespread pain has produced a group of subjects whose pain is (a) likely to be more "widespread" and (b) is associated more strongly with factors such as psychological disturbance, fatigue, sleep problems, and tender points, and may be more appropriate in epidemiological studies.

Advanced Cosmic-Ray Composition Experiment for Space Station (ACCESS): ACCESS Accommodation Study Report

NASA Technical Reports Server (NTRS)

Wilson, Thomas L. (Editor); Wefel, John P. (Editor)

1999-01-01

In 1994 NASA Administrator selected the first high-energy particle physics experiment for the Space Station, the Alpha Magnetic Spectrometer (AMS), to place a magnetic spectrometer in Earth orbit and search for cosmic antimatter. A natural consequence of this decision was that NASA would begin to explore cost-effective ways through which the design and implementation of AMS might benefit other promising payload experiments. The first such experiment to come forward was Advanced Cosmic-Ray Composition Experiment for Space Station (ACCESS) in 1996. It was proposed as a new mission concept in space physics to attach a cosmic-ray experiment of weight, volume, and geometry similar to the AMS on the International Space Station (ISS), and replace the latter as its successor when the AMS is returned to Earth. This was to be an extension of NASA's suborbital balloon program, with balloon payloads serving as the precursor flights and heritage for ACCESS. The balloon programs have always been a cost-effective NASA resource since the particle physics instrumentation for balloon and space applications are directly related. The next step was to expand the process, pooling together expertise from various NASA centers and universities while opening up definition of the ACCESS science goals to the international community through the standard practice of peer review. This process is still ongoing, and the accommodation study presented here will discuss the baseline definition of ACCESS as we understand it today.

Effects of strain rate, mixing ratio, and stress-strain definition on the mechanical behavior of the polydimethylsiloxane (PDMS) material as related to its biological applications.

Khanafer, Khalil; Duprey, Ambroise; Schlicht, Marty; Berguer, Ramon

2009-04-01

Tensile tests on Polydimethylsiloxane (PDMS) materials were conducted to illustrate the effects of mixing ratio, definition of the stress-strain curve, and the strain rate on the elastic modulus and stress-strain curve. PDMS specimens were prepared according to the ASTM standards for elastic materials. Our results indicate that the physiological elastic modulus depends strongly on the definition of the stress-strain curve, mixing ratio, and the strain rate. For various mixing ratios and strain rates, true stress-strain definition results in higher stress and elastic modulus compared with engineering stress-strain and true stress-engineering strain definitions. The elastic modulus increases as the mixing ratio increases up-to 9:1 ratio after which the elastic modulus begins to decrease even as the mixing ratio continues to increase. The results presented in this study will be helpful to assist the design of in vitro experiments to mimic blood flow in arteries and to understand the complex interaction between blood flow and the walls of arteries using PDMS elastomer.

OBJECTIVE The authors examined the development of psychotic experiences and psychotic disorders in a large population-based sample of young adults and explored their relationship to psychotic phenomena earlier in childhood. METHOD The authors conducted a longitudinal birth cohort study of individuals assessed with the semistructured Psychosis-Like Symptom Interviews at ages 12 and 18 years. RESULTS Of the 4,724 individuals interviewed at age 18, 433 (9.2%) had either suspected (N=203 [4.3%]) or definite (N=230 [4.9%]) psychotic experiences. Of these, 79 (1.7%) met criteria for a psychotic disorder, and of those, only 50% sought professional help. All psychotic outcomes were more likely in young women and in those from socioeconomically disadvantaged backgrounds. Of the participants who had psychotic experiences at age 12, 78.7% had remitted by age 18. The risk of psychotic disorders at age 18 was greater in those with suspected (odds ratio=5.6, 95% CI=2.6-12.1) and especially in those with definite (odds ratio=12.7, 95% CI=6.2-26.1) psychotic experiences at age 12, and also among those with psychotic experiences at age 12 attributed to sleep or fever or with nonpsychotic experiences such as depersonalization. The positive predictive values for increasing frequency of experiences at age 12 predicting psychotic disorders at age 18 ranged from 5.5% to 22.8%. CONCLUSIONS Despite evidence for a continuum of psychotic experiences from as early as age 12, positive predictive values for predicting psychotic disorders were too low to offer real potential for targeted interventions. Psychotic disorders in young adults are relatively uncommon, but they constitute an important unmet need for care given that half of the individuals in this study who met criteria for a psychiatric disorder had not sought help for these problems despite high levels of associated distress and impairment.

Although genius has been defined in the dictionary as requiring an IQ above 140, this definition depends on an arbitrary methodological decision made by Lewis Terman for his longitudinal study of more than 1500 intellectually gifted children, a study that occupies four of the five volumes of Genetic Studies of Genius. Yet, only the second volume, by Catharine Cox, studied bona fide geniuses, by applying historiometric methods to 301 highly eminent creators and leaders. After defining historiometric research, I examine the difference between historical genius and intellectual giftedness with respect to heterogeneous intellects, personality differences, and early development and show that the actual relation between IQ and genius is small and heavily contingent on domain-specific assessment, the operation of traits like persistence and openness to experience, and the impact of diversifying experiences, including both developmental adversity and subclinical psychopathology. Hence, the dictionary definition of "genius" has minimal, if any, justification. If, using historiometric methods, one works backward from recognized geniuses, such as those studied by Cox, one might not obtain the kind of sample that Terman obtained for his longitudinal study. The two methods produce two distinct subgroups of the larger population. © 2016 New York Academy of Sciences.

Sublexical and lexico-syntactic factors in gender access in Spanish.

Afonso, Olivia; Domínguez, Alberto; Alvarez, Carlos J; Morales, David

2014-02-01

The influence of sublexical and lexico-syntactic factors during the grammatical gender assignment process in Spanish was studied in two experiments using the gender decision task. In Experiment 1, the regularity of the ending of gender-marked nouns (masculine nouns ended in -o and feminine nouns ended in -a) and of nouns with gender-correlated but unmarked word-endings (e.g., -ad) was manipulated. The results showed that regularity affected reaction times and error rates only in the case of gender-marked nouns, suggesting that the mere statistical distribution of a word-ending across genders is not responsible for the regularity effect. In Experiment 2, gender-marked nouns and gender-unmarked nouns were preceded by a masked prime which could be a definite article (which provides information about the gender of the noun) or a possessive pronoun (which does not contain gender information). The presentation of the definite article led to shorter reaction times and less errors only when the word-ending was different from -o or -a. Taken together, these results indicate that gender assignment in Spanish is carried out through different processes depending on the noun ending: gender decisions for gender-marked nouns are based on the gender-to-ending distribution. Meanwhile, gender decisions for unmarked nouns seem to require the retrieval of the corresponding definite grammatical article, regardless of the statistical distribution of the noun ending across genders.

Junior doctor psychiatry placements in hospital and community settings: a phenomenological study.

PubMed

Beattie, Sharon; Crampton, Paul E S; Schwarzlose, Cathleen; Kumar, Namita; Cornwall, Peter L

2017-09-27

The proportion of junior doctors required to complete psychiatry placements in the UK has increased, due in part to vacant training posts and psychiatry career workforce shortages, as can be seen across the world. The aim of this study was to understand the lived experience of a Foundation Year 1 junior doctor psychiatry placement and to understand how job components influence attitudes. The study was conducted using a cross-sectional qualitative phenomenological approach. Hospital and community psychiatry department settings in the North East of England, UK. In total, 14 Foundation Year 1 junior doctors were interviewed including seven men and seven women aged between 23 and 34 years. The majority had completed their medical degree in the UK and were White British. The lived experience of a junior doctor psychiatry placement was understood by three core themes: exposure to patient recovery, connectedness with others in the healthcare team and subjective interpretations of psychiatry. The experiences were moderated by instances of role definition, reaction to the specialty and the organisational fit of the junior doctor capacity in the specialty. The study reinforces and adds to the literature by identifying connectedness as being important for both job satisfaction and morale, which is currently damaged within the junior doctor population. The study provides in-depth insights into the lived experience of psychiatry placements and can be taken forward by educationalists to ensure the placements are meaningful experiences for junior doctors by developing role definition, belonging, structure and psychiatric care responsibility. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Comparison of treatment outcome using two definitions of rapid cycling in subjects with bipolar II disorder.

PubMed

Amsterdam, Jay D; Lorenzo-Luaces, Lorenzo; DeRubeis, Robert J

2017-02-01

We examined differences in treatment outcome between Diagnostic and Statistical Manual Fourth Edition (DSM-IV)-defined rapid cycling and average lifetime-defined rapid cycling in subjects with bipolar II disorder. We hypothesized that, compared with the DSM-IV definition, the average lifetime definition of rapid cycling may better identify subjects with a history of more mood lability and a greater likelihood of hypomanic symptom induction during long-term treatment. Subjects ≥18 years old with a bipolar II major depressive episode (n=129) were categorized into DSM-IV- and average lifetime-defined rapid cycling and prospectively treated with either venlafaxine or lithium monotherapy for 12 weeks. Responders (n=59) received continuation monotherapy for six additional months. These exploratory analyses found moderate agreement between the two rapid-cycling definitions (κ=0.56). The lifetime definition captured subjects with more chronic courses of bipolar II depression, whereas the DSM-IV definition captured subjects with more acute symptoms of hypomania. There was no difference between rapid-cycling definitions with respect to the response to acute venlafaxine or lithium monotherapy. However, the lifetime definition was slightly superior to the DSM-IV definition in identifying subjects who went on to experience hypomanic symptoms during continuation therapy. Although sample sizes were limited, the findings suggest that the lifetime definition of rapid cycling may identify individuals with a chronic rapid-cycling course and may also be slightly superior to the DSM-IV definition in identifying individuals with hypomania during relapse-prevention therapy. These findings are preliminary in nature and need replication in larger, prospective, bipolar II studies. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Atmospheric lidar multi-user instrument system definition study

NASA Technical Reports Server (NTRS)

Greco, R. V. (Editor)

1980-01-01

A spaceborne lidar system for atmospheric studies was defined. The primary input was the Science Objectives Experiment Description and Evolutionary Flow Document. The first task of the study was to perform an experiment evolutionary analysis of the SEED. The second task was the system definition effort of the instrument system. The third task was the generation of a program plan for the hardware phase. The fourth task was the supporting studies which included a Shuttle deficiency analysis, a preliminary safety hazard analysis, the identification of long lead items, and development studies required. As a result of the study an evolutionary Lidar Multi-User Instrument System (MUIS) was defined. The MUIS occupies a full Spacelab pallet and has a weight of 1300 kg. The Lidar MUIS laser provides a 2 joule frequency doubled Nd:YAG laser that can also pump a tuneable dye laser wide frequency range and bandwidth. The MUIS includes a 1.25 meter diameter aperture Cassegrain receiver, with a moveable secondary mirror to provide precise alignment with the laser. The receiver can transmit the return signal to three single and multiple photomultiple tube detectors by use of a rotating fold mirror. It is concluded that the Lidar MUIS proceed to program implementation.

Gas-Grain Simulation Facility (GGSF). Volume 2: Conceptual design definition

NASA Technical Reports Server (NTRS)

Zamel, James M.

1993-01-01

This document is Volume 2 of the Final Report for the Phase A Study of the Gas-Grain Simulation Facility (GGSF), and presents the GGSF Conceptual Design. It is a follow-on to the Volume 1 Facility Definition Study, NASA report CR 177606. The development of a conceptual design for a Space Station Freedom (SSF) facility that will be used for investigating particle interactions in varying environments, including various gas mixtures, pressures, and temperatures is delineated. It's not possible to study these experiments on earth due to the long reaction times associated with this type of phenomena, hence the need for extended periods of microgravity. The particle types will vary in composition (solids and liquids), sizes (from submicrons to centimeters), and concentrations (from single particles to 10(exp 10) per cubic centimeter). The results of the experiments pursued in the GGSF will benefit a variety of scientific inquiries. These investigations span such diverse topics as the formation of planets and planetary rings, cloud and haze processes in planetary atmospheres, the composition and structure of astrophysical objects, and the viability of airborne microbes (e.g., in a manned spacecraft).

Do We Need to Design Course-Based Undergraduate Research Experiences for Authenticity?

Rowland, Susan; Pedwell, Rhianna; Lawrie, Gwen; Lovie-Toon, Joseph; Hung, Yu

2016-01-01

The recent push for more authentic teaching and learning in science, technology, engineering, and mathematics indicates a shared agreement that undergraduates require greater exposure to professional practices. There is considerable variation, however, in how “authentic” science education is defined. In this paper we present our definition of authenticity as it applies to an “authentic” large-scale undergraduate research experience (ALURE); we also look to the literature and the student voice for alternate perceptions around this concept. A metareview of science education literature confirmed the inconsistency in definitions and application of the notion of authentic science education. An exploration of how authenticity was explained in 604 reflections from ALURE and traditional laboratory students revealed contrasting and surprising notions and experiences of authenticity. We consider the student experience in terms of alignment with 1) the intent of our designed curriculum and 2) the literature definitions of authentic science education. These findings contribute to the conversation surrounding authenticity in science education. They suggest two things: 1) educational experiences can have significant authenticity for the participants, even when there is no purposeful design for authentic practice, and 2) the continuing discussion of and design for authenticity in UREs may be redundant.

Immediate effects of anticipatory coarticulation in spoken-word recognition

PubMed Central

Salverda, Anne Pier; Kleinschmidt, Dave; Tanenhaus, Michael K.

2014-01-01

Two visual-world experiments examined listeners’ use of pre word-onset anticipatory coarticulation in spoken-word recognition. Experiment 1 established the shortest lag with which information in the speech signal influences eye-movement control, using stimuli such as “The … ladder is the target”. With a neutral token of the definite article preceding the target word, saccades to the referent were not more likely than saccades to an unrelated distractor until 200–240 ms after the onset of the target word. In Experiment 2, utterances contained definite articles which contained natural anticipatory coarticulation pertaining to the onset of the target word (“ The ladder … is the target”). A simple Gaussian classifier was able to predict the initial sound of the upcoming target word from formant information from the first few pitch periods of the article’s vowel. With these stimuli, effects of speech on eye-movement control began about 70 ms earlier than in Experiment 1, suggesting rapid use of anticipatory coarticulation. The results are interpreted as support for “data explanation” approaches to spoken-word recognition. Methodological implications for visual-world studies are also discussed. PMID:24511179

Defining interdisciplinary research: conclusions from a critical review of the literature.

To summarize findings from a systematic exploration of existing literature and views regarding interdisciplinarity, to discuss themes and components of such work, and to propose a theoretically based definition of interdisciplinary research. Two major data sources were used: interviews with researchers from various disciplines, and a systematic review of the education, business, and health care literature from January 1980 through January 2005. Systematic review of literature, one-on-one interviews, field test (survey). We reviewed 14 definitions of interdisciplinarity, the characteristics of 42 interdisciplinary research publications from multiple fields of study, and 14 researcher interviews to arrive at a preliminary definition of interdisciplinary research. That definition was then field tested by 12 individuals with interdisciplinary research experience, and their responses incorporated into the definition of interdisciplinary research proposed in this paper. Three key definitional characteristics were identified: the qualitative mode of research (and its theoretical underpinnings), existence of a continuum of synthesis among disciplines, and the desired outcome of the interdisciplinary research. Existing literature from several fields did not provide a definition for interdisciplinary research of sufficient specificity to facilitate activities such as identification of the competencies, structure, and resources needed for health care and health policy research. This analysis led to the proposed definition, which is designed to aid decision makers in funding agencies/program committees and researchers to identify and take full advantage the interdisciplinary approach, and to serve as a basis for competency-based formalized training to provide researchers with interdisciplinary skills.

Teaching Weight-Gravity and Gravitation in Middle School. Testing a New Instructional Approach

NASA Astrophysics Data System (ADS)

Galili, Igal; Bar, Varda; Brosh, Yaffa

2016-12-01

This study deals with the school instruction of the concept of weight. The historical review reveals the major steps in changing weight definition reflecting the epistemological changes in physics. The latest change drawing on the operation of weighing has been not widely copied into physics education. We compared the older instruction based on the gravitational definition of weight with the newer one based on the operational definition. The experimental teaching was applied in two versions, simpler and extended. The study examined the impact of this instruction on the middle school students in regular teaching environment. The experiment involved three groups ( N = 486) of 14-year-old students (ninth grade). The assessment drew on a written questionnaire and personal interviews. The elicited schemes of conceptual knowledge allowed to evaluate the impact on students' pertinent knowledge. The advantage of the new teaching manifested itself in the significant decrease of the well-known misconceptions such as "space causes weightlessness," "weight is an unchanged property of the body considered," and "heavier objects fall faster". The twofold advantage—epistemological and conceptual—of the operational definition of weight supports the correspondent curricular changes of its adoption.

After the publication of the new definition for sepsis and septic shock, our objective is to analyse the evolution of patients admitted to ICU with an infection process using the previous and new recommendations. This is a sub-analysis of a previous observational prospective study. We included 98 patients admitted to ICU from the emergency department due to infection during an 18-month period. We studied the clinical evolution during ICU admission and hospital mortality. According to Sepsis-2 definition, 78% percent had septic shock and using Sepsis-3 criteria, 52%; hospital mortality was 29 and 41%, respectively. The RR of hospital mortality of septic shock was 10.3 (95% CI: 2.8-37.5) compared to patients without shock. The 30-day probability survival of patients with sepsis and septic shock were 78% and 68%, respectively (long rank < 0.001). In our experience, the incorporation of the SOFA score and lactate levels to the new definition could help improve the evaluation of risk of hospital death. Copyright © 2018 Elsevier España, S.L.U.

The impact of definition and question order on the prevalence of bullying victimization using student self-reports.

PubMed

Huang, Francis L; Cornell, Dewey G

2015-12-01

Accurate measurement is essential to determining the prevalence of bullying and evaluating the effectiveness of intervention efforts. The most common measurement approach is through anonymous self-report surveys, but previous studies have suggested that students do not adhere to standard definitions of bullying and may be influenced by the order of questions about types of victimization. In the current study, we have presented findings from 2 randomized experiments designed to determine (a) the impact of using or not using a definition of bullying and (b) asking about general versus specific types of bullying victimization and how the order of these questions affects victimization-prevalence rates. The study was conducted using a sample of 17,301 students attending 119 high schools. Findings indicate that the use of a definition had no impact on prevalence rates, but asking specific bullying-victimization questions (e.g., "I have been verbally bullied at school") prior to general bullying-victimization questions (e.g., "I have been bullied at school"), resulted in a 29-76% increase in victimization-prevalence rates. Results suggest that surveys that ask general-to-specific bullying-victimization questions, such as those found in national and international surveys, may be underreporting bullying victimization.

Navigating the self in maternity care: how Chinese midwives work on their professional identity in hospital setting.

PubMed

Zhang, Jing; Haycock-Stuart, Elaine; Mander, Rosemary; Hamilton, Lorna

2015-03-01

to explore the strategies Chinese midwives employed to work on their professional identity in hospital setting and the consequence of such identity work. this paper draws upon findings from a Constructivist Grounded Theory study that explored the professional identity construction of 15 Chinese midwives with a mixture of midwifery experiences, practising in three different types of hospital settings in a capital city in Southeast China. The accounts from participants in the form of in-depth individual interviews were collected. Work journals voluntarily provided by three participants were also included. in everyday practice, hospital midwives in China were working on their professional identity in relation to two definitions of the midwife: the external definition ('obstetric nurse'), bound up in the idea of risk management under the medical model of their work organisations; and the internal definition ('professional midwife'), associated with the philosophy of normal birth advocacy in the professional discourse. Six strategies for identity work were identified and grouped into two principle categories: 'compromise' and 'engagement'. The adoption of each strategy involved a constant negotiation between the external and internal definitions of the midwife, being influenced by midwifery experiences, relationships with women, opportunities for professional development and the definition of the situation. A 'hybrid identity', which demonstrated the dynamic nature of midwifery professional identity, was constructed as a result. this paper explored the dynamic nature of midwifery professional identity. This exploration contributes to the body of knowledge regarding understanding the professional identity of hospital midwives in China, while also extending the current theoretical knowledge of identity work by elaborating on the various strategies individuals use to work on their professional identity in the workplace.

Al-Azemi, Rashed; Artun, Jon

2010-01-01

Our purpose was to determine the orthodontic treatment need in adolescent Kuwaitis, adjusting for treatment experience and acquired need due to mesial migration or loss of the first molars, and to assess the orthodontic manpower requirements. A population-based sample of 753 boys and 728 girls, representing about 7% of all 13- to 14-year-old Kuwaitis, was examined in a classroom setting. Orthodontic treatment need was graded according to the Dental Health Component (DHC) and the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Subjects with treatment experience were scored on initial study models. The DHC and AC grades were categorized in 3 groups and aggregated to 3 IOTN groups according to the highest DHC or AC group. Group 1 was labeled as 'no need', 2 as 'moderate need', and 3 as 'definite need for orthodontic treatment'. According to the IOTN, 31.1% of the subjects demonstrated a definite need and 40.2% no need for treatment. Excluding DHC group 3 categories attributed to mesial migration and/or loss of first molars, definite need was reduced to 23.9%. Definite treatment need was more prevalent when estimated according to the DHC than according to the AC, while moderate and no need were more prevalent according to the AC (p < 0.001). No gender differences were detected (p > 0.05). About 30% of adolescent Kuwaitis have definite need for orthodontic treatment. The prevalence may be reduced towards 25%, provided loss or mesial migration of the first molars can be prevented. About 50-60 orthodontists are needed to meet the severe need in adolescent Kuwaitis.

Low-gravity impact experiments: Progress toward a facility definition

NASA Technical Reports Server (NTRS)

Cintala, M. J.

1986-01-01

Innumerable efforts were made to understand the cratering process and its ramifications in terms of planetary observations, during which the role of gravity has often come into question. Well known facilities and experiments both were devoted in many cases to unraveling the contribution of gravitational acceleration to cratering mechanisms. Included among these are the explosion experiments in low gravity aircraft, the drop platform experiments, and the high gravity centrifuge experiments. Considerable insight into the effects of gravity was gained. Most investigations were confined to terrestrial laboratories. It is in this light that the Space Station is being examined as a vehicle with the potential to support otherwise impractical impact experiments. The results of studies performed by members of the planetary cratering community are summarized.

Feeling Comfortable: A Humanbecoming Perspective.

Dobrzykowski, Teresa M

2017-01-01

Feeling comfortable is a universal living experience. From the worldview of the humanbecoming paradigm, concept inventing is an appropriate method to expand understanding and knowledge of universal experiences. The purpose of this article is to provide a synthetic definition of feeling comfortable using the concept inventing process. Through concept inventing, a synthetic definition of feeling comfortable emerged as penetrating quietude amid potential upheaval arising with opportunities and restrictions with envisioning the familiar anew. Further development of the concept through qualitative research is recommended.

An examination of the disparity between self-identified versus legally identified rape victimization: A pilot study.

PubMed

Marsil, Dorothy F; McNamara, Corinne

2016-07-01

Researchers compared rape victimization based on self-identification to the current federal legal definition in a pilot study of college students. The sample was comprised of 1,648 (69.8% female; 30.2% male) college students who completed the Sexual Experiences Survey-Short Form Victimization (SES-SFV) online. Based on the current legal definition of rape, 9.4% (11.1% female; 5.2% male) of students had been raped since being enrolled, but only 2.9% of students self-identified as being raped. Moreover, 15.1% of students reported ever being raped, with females acknowledging higher rates (19.7%) than males (4.3%). Rape continues to be a major issue for colleges and universities. A serious concern is the disparity between the number of those who met the behavioral criteria for rape victimization based on the current legal definition, but who did not self-identify as a victim. Universities must address this disparity by using multiple measures to assess the prevalence of sexual violence on campus.

The Course-Based Undergraduate Research Experiences Network (CUREnet) was initiated in 2012 with funding from the National Science Foundation program for Research Coordination Networks in Undergraduate Biology Education. CUREnet aims to address topics, problems, and opportunities inherent to integrating research experiences into undergraduate courses. During CUREnet meetings and discussions, it became apparent that there is need for a clear definition of what constitutes a CURE and systematic exploration of what makes CUREs meaningful in terms of student learning. Thus, we assembled a small working group of people with expertise in CURE instruction and assessment to: 1) draft an operational definition of a CURE, with the aim of defining what makes a laboratory course or project a “research experience”; 2) summarize research on CUREs, as well as findings from studies of undergraduate research internships that would be useful for thinking about how students are influenced by participating in CUREs; and 3) identify areas of greatest need with respect to CURE assessment, and directions for future research on and evaluation of CUREs. This report summarizes the outcomes and recommendations of this meeting. PMID:24591501

Cancer and beyond: the question of survivorship.

PubMed

Breaden, K

1997-11-01

Today, more people are surviving cancer as a result of improved treatment and early diagnosis. In Australia, the 5-year survival rate for persons diagnosed with cancer is now approaching 50%. Although there is a growing population of cancer survivors, little is known about what surviving entails. Traditionally, a survivor has been defined as one who has been disease-free for more than 5 years. However, this definition does not take into account the experience nor the process of survival and the aim of this article is to document the process of surviving cancer as reflected in the experiences of cancer survivors. Using a method of hermeneutic phenomenology (as described by van Manen), the study draws on the stories of six women, who by their definition, are surviving cancer. A discussion of themes has been structured according to the everyday experiences of living in a body and living in time. The women describe a survival process that includes: 'feeling whole again'; 'the body as the house of suspicion'; 'the future in question'; 'changes in time'; 'lucky to be alive'; and 'sharing the journey'.

Computer calculations were then made of the spectral radiance signature of each of 25 candidate targets as seen by a satellite sensor system. An imaging system capable of recognizing, acquiring and tracking specific generic type surface features was defined. A preliminary experiment definition and design of a video Landmark Acquisition and Tracking system is given. This device will search a 10-mile swath while orbiting the earth, looking for land/water interfaces such as coastlines and rivers.

Identifying bully victims: definitional versus behavioral approaches.

PubMed

Green, Jennifer Greif; Felix, Erika D; Sharkey, Jill D; Furlong, Michael J; Kras, Jennifer E

2013-06-01

Schools frequently assess bullying and the Olweus Bully/Victimization Questionnaire (BVQ; Olweus, 1996) is the most widely adopted tool for this purpose. The BVQ is a self-report survey that uses a definitional measurement method--describing "bullying" as involving repeated, intentional aggression in a relationship where there is an imbalance of power and then asking respondents to indicate how frequently they experienced this type of victimization. Few studies have examined BVQ validity and whether this definitional method truly identifies the repetition and power differential that distinguish bullying from other forms of peer victimization. This study examined the concurrent validity of the BVQ definitional question among 435 students reporting peer victimization. BVQ definitional responses were compared with responses to a behavioral measure that did not use the term "bullying" but, instead, included items that asked about its defining characteristics (repetition, intentionality, power imbalance). Concordance between the two approaches was moderate, with an area under the receiver operating curve of .72. BVQ responses were more strongly associated with students indicating repeated victimization and multiple forms of victimization, than with power imbalance in their relationship with the bully. Findings indicate that the BVQ is a valid measure of repeated victimization and a broad range of victimization experiences but may not detect the more subtle and complex power imbalances that distinguish bullying from other forms of peer victimization.

Black lung: the social production of diseas

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

Smith, B.E.

1981-01-01

The black lung movement that erupted in West Virginia in 1968 was not simply a struggle for recognition of an occupational disease; it grew into a bitter controversy over who would control the definition of that disease. This article examines the historical background and medical politics of that controversy, arguing that black lung was socially produced and defined on several different levels. As a medical construct, the changing definitions of this disease can be traced to major shifts in the political economy of the coal industry. As an occupational disease, the history of black lung is internally related to themore » history of the workplace in which it is produced. As the object of a mass movement, black lung acquired a political definition that grew out of the collective experience of miners and their families. The definition of disease with which black lung activists challenged the medical establishment has historical roots and justification; their experience suggests that other health advocates may need to redefine the diseases they hope to eradicate.« less

Maintaining and disseminating the kilogram following its redefinition

NASA Astrophysics Data System (ADS)

Stock, M.; Davidson, S.; Fang, H.; Milton, M.; de Mirandés, E.; Richard, P.; Sutton, C.

2017-12-01

The new definition of the kilogram, which is expected to be adopted by the General Conference on Weights and Measures in 2018, will bring some major changes to mass metrology. The most fundamental change will be the replacement of the present artefact-based definition with a universal definition, enabling in principle any National Metrology Institute (NMI) to realize the kilogram. The principles for the realization and dissemination of the kilogram in the revised SI are described in the mise en pratique of the definition of the kilogram. This paper provides some additional information and explains how traceability can be obtained by NMIs that do not operate a primary experiment to realize the definition of the kilogram.

Treatment integrity of school-based interventions with children in the journal of applied behavior analysis 1991-2005.

PubMed

McIntyre, Laura Lee; Gresham, Frank M; DiGennaro, Florence D; Reed, Derek D

2007-01-01

We reviewed all school-based experimental studies with individuals 0 to 18 years published in the Journal of Applied Behavior Analysis (JABA) between 1991 and 2005. A total of 142 articles (152 studies) that met review criteria were included. Nearly all (95%) of these experiments provided an operational definition of the independent variable, but only 30% of the studies provided treatment integrity data. Nearly half of studies (45%) were judged to be at high risk for treatment inaccuracies. Treatment integrity data were more likely to be included in studies that used teachers, multiple treatment agents, or both. Although there was a substantial increase in reporting operational definitions of independent variables, results suggest that there was only a modest improvement in reported integrity over the past 30 years of JABA studies. Recommendations for research and practice are discussed.

Emotions are both central to life experience itself and highly pertinent to various disciplines, including neuroscience, psychology, social studies, philosophy, and the arts. The definition of emotion lies at the interface of nature and culture reflecting an understanding of the components that shape emotional states and experiences across time and cultures. This review describes how the concept of emotion developed in Western thought, from the Renaissance notion of the passions to the 19th century idea of 'emotion'.

Joint Control: A Discussion of Recent Research

The discrimination of the onset of joint control is an important interpretive tool in explaining matching behavior and other complex phenomena, but the difficulty of getting experimental control of all relevant variables stands in the way of a definitive experiment. The studies in the present issue of The Analysis of Verbal Behavior illustrate how modest experiments can take their place in a web of interpretation to make a strong case that joint control is a necessary element of such phenomena.

Tunneling Time and Weak Measurement in Strong Field Ionization.

PubMed

Zimmermann, Tomáš; Mishra, Siddhartha; Doran, Brent R; Gordon, Daniel F; Landsman, Alexandra S

2016-06-10

Tunneling delays represent a hotly debated topic, with many conflicting definitions and little consensus on when and if such definitions accurately describe the physical observables. Here, we relate these different definitions to distinct experimental observables in strong field ionization, finding that two definitions, Larmor time and Bohmian time, are compatible with the attoclock observable and the resonance lifetime of a bound state, respectively. Both of these definitions are closely connected to the theory of weak measurement, with Larmor time being the weak measurement value of tunneling time and Bohmian trajectory corresponding to the average particle trajectory, which has been recently reconstructed using weak measurement in a two-slit experiment [S. Kocsis, B. Braverman, S. Ravets, M. J. Stevens, R. P. Mirin, L. K. Shalm, and A. M. Steinberg, Science 332, 1170 (2011)]. We demonstrate a big discrepancy in strong field ionization between the Bohmian and weak measurement values of tunneling time, and we suggest this arises because the tunneling time is calculated for a small probability postselected ensemble of electrons. Our results have important implications for the interpretation of experiments in attosecond science, suggesting that tunneling is unlikely to be an instantaneous process.

Exon definition as a potential negative force against intron losses in evolution.

PubMed

Niu, Deng-Ke

2008-11-13

Previous studies have indicated that the wide variation in intron density (the number of introns per gene) among different eukaryotes largely reflects varying degrees of intron loss during evolution. The most popular model, which suggests that organisms lose introns through a mechanism in which reverse-transcribed cDNA recombines with the genomic DNA, concerns only one mutational force. Using exons as the units of splicing-site recognition, exon definition constrains the length of exons. An intron-loss event results in fusion of flanking exons and thus a larger exon. The large size of the newborn exon may cause splicing errors, i.e., exon skipping, if the splicing of pre-mRNAs is initiated by exon definition. By contrast, if the splicing of pre-mRNAs is initiated by intron definition, intron loss does not matter. Exon definition may thus be a selective force against intron loss. An organism with a high frequency of exon definition is expected to experience a low rate of intron loss throughout evolution and have a high density of spliceosomal introns. The majority of spliceosomal introns in vertebrates may be maintained during evolution not because of potential functions, but because of their splicing mechanism (i.e., exon definition). Further research is required to determine whether exon definition is a negative force in maintaining the high intron density of vertebrates. This article was reviewed by Dr. Scott W. Roy (nominated by Dr. John Logsdon), Dr.Eugene V. Koonin, and Dr. Igor B. Rogozin (nominated by Dr. Mikhail Gelfand). For the full reviews,please go to the Reviewers' comments section.

What Can Be Learned From a Laboratory Model of Conceptual Change? Descriptive Findings and Methodological Issues

NASA Astrophysics Data System (ADS)

Ohlsson, Stellan; Cosejo, David G.

2014-07-01

The problem of how people process novel and unexpected information— deep learning (Ohlsson in Deep learning: how the mind overrides experience. Cambridge University Press, New York, 2011)—is central to several fields of research, including creativity, belief revision, and conceptual change. Researchers have not converged on a single theory for conceptual change, nor has any one theory been decisively falsified. One contributing reason is the difficulty of collecting informative data in this field. We propose that the commonly used methodologies of historical analysis, classroom interventions, and developmental studies, although indispensible, can be supplemented with studies of laboratory models of conceptual change. We introduce re- categorization, an experimental paradigm in which learners transition from one definition of a categorical concept to another, incompatible definition of the same concept, a simple form of conceptual change. We describe a re-categorization experiment, report some descriptive findings pertaining to the effects of category complexity, the temporal unfolding of learning, and the nature of the learner's final knowledge state. We end with a brief discussion of ways in which the re-categorization model can be improved.

Atmospheric, Magnetospheric, and Plasmas in Space (AMPS) spacelab payload definition study, technical summary document

NASA Technical Reports Server (NTRS)

Keeley, J. T.

1976-01-01

Some 60 instrument candidates and 80 possible science investigations were evaluated. The early analysis emphasized the science aspect in terms of the functional requirements for each of the potential experiments identified by the AMPS science working group. These requirements were then used for the grouping of instruments into practical payloads which would fit the capabilities of the Shuttle/Spacelab. This analysis resulted in the definition of eleven different AMPS configurations. The data were then used to define a typical set of requirements for a flexible AMPS laboratory. The data gathered to this point showed that a planned sequential buildup of the laboratory would be necessary to meet both physical and funding limitations. This led to the definition of five strawman payloads by the science working group, which were used to establish a conceptual laboratory and to define preliminary design of a configuration which could satisfy AMPS needs during the early program period.

The U.S./Canadian GEO Bilateral Drought Indices and Definitions Study: Implications for the Canadian Drought Monitor and a Global Drought Early Warning System

NASA Astrophysics Data System (ADS)

Hadwen, T.; Heim, R. R.; Howard, A.

2011-12-01

Drought is a difficult phenomenon to define; the way in which it is monitored, measured, assessed and even the very definition of drought vary from location to location based on the regional climate and the potential impacts. Drought is not an absolute condition but an evolving state brought on by relatively dry weather, growing more severe over time. There are many factors that define a drought and many more that define its impacts. Many definitions and indices are based solely on meteorological characteristics. Although this approach has merit, it is often necessary to go further to define those meteorological conditions in a way that is relevant to the land and water use in a region. A Drought Indices and Definitions Study was initiated in 2010 as part of a GEO Bilateral effort to examine drought across the U.S. and Canada. The Study's deliverables will include a survey of the drought indices used to monitor drought, and a bibliography of research addressing the nature of drought, across the diverse climates of the continent. With an increasing pressure to utilize drought monitoring as a primary indicator of need for disaster assistance, the reliability of drought indices must be validated and utilized in appropriate in various regions. In 2009, following over five years of participation in the North American Drought Monitor (NA-DM), the National Agroclimate Information Service of Agriculture and Agri-Food Canada initiated a project to develop a Canadian Drought Monitor (Can-DM), based on primary principles used in the NA-DM and the US Drought Monitor (US-DM). The process of developing an operational monitoring tool and using drought indices in a vast and environmentally diverse country has been challenging. in Canada, many of the commonly used indices are not appropriate in certain regions or data densities do not allow for proper use. This paper will discuss the experiences that the Can-DM team has had dealing with these challenges, how these experiences provide recommendations for a global drought early warning system, and implications of the Drought Indices and Definitions Study for improving both the Can-DM and a global drought early warning system.

Linguistic analysis of project ownership for undergraduate research experiences.

PubMed

Hanauer, D I; Frederick, J; Fotinakes, B; Strobel, S A

2012-01-01

We used computational linguistic and content analyses to explore the concept of project ownership for undergraduate research. We used linguistic analysis of student interview data to develop a quantitative methodology for assessing project ownership and applied this method to measure degrees of project ownership expressed by students in relation to different types of educational research experiences. The results of the study suggest that the design of a research experience significantly influences the degree of project ownership expressed by students when they describe those experiences. The analysis identified both positive and negative aspects of project ownership and provided a working definition for how a student experiences his or her research opportunity. These elements suggest several features that could be incorporated into an undergraduate research experience to foster a student's sense of project ownership.

On-orbit technology experiment facility definition

Russell, Richard A.; Buchan, Robert W.; Gates, Richard M.

1988-01-01

A study was conducted to identify on-orbit integrated facility needs to support in-space technology experiments on the Space Station and associated free flyers. In particular, the first task was to examine the proposed technology development missions (TDMX's) from the model mission set and other proposed experimental facilities, both individually and by theme, to determine how and if the experiments might be combined, what equipment might be shared, what equipment might be used as generic equipment for continued experimentation, and what experiments will conflict with the conduct of other experiments or Space Station operations. Then using these results, to determine on-orbit facility needs to optimize the implementation of technology payloads. Finally, to develop one or more scenarios, design concepts, and outfitting requirements for implementation of onboard technology experiments.

"At My Age … ": Defining Sexual Wellness in Mid- and Later Life.

PubMed

Syme, Maggie L; Cohn, Tracy J; Stoffregen, Sydney; Kaempfe, Hanna; Schippers, Desiree

2018-04-18

Sexual wellness is integral to quality of life across the life span, despite ageist stereotypes suggesting sexual expression ends at midlife. However, conceptualizing sexual wellness in mid- and later life is complicated by a dysfunction-based narrative, lack of a sex-positive aging framework, and existing measures that are age irrelevant and limited in scope. This study aimed to address these limitations by providing a conceptualization of sexual wellness grounded in definitions from midlife and older adults. A sample of 373 midlife and older adults (M = 60, SD = 5.84) in the United States provided a definition of sexual wellness. Using thematic analysis, multiple researchers coded qualitative responses, and results suggested a biopsychosocial-cultural framework. Findings reflect that midlife and older adults provide multifaceted definitions inclusive of various behavioral experiences, including disengaging from sex. They are also keenly aware of physical and psychological limitations and strengths, and emphasize mutual experiences and synchronicity. Midlife and older adults also reflect on age, drawing comparisons to different phases of life and often displaying adaptability in adjusting expectations. When conceptualizing sexual wellness in this population it is imperative to capture this multidimensionality, include those who are not actively engaging in sex, and be aware of the influence of ageist and dys/function narratives.

A number of factors can influence the reported outcomes of transsphenoidal surgery (TSS) for Cushing's disease - including different remission and recurrence criteria, for which there is no consensus. Therefore, a comparative analysis of the best treatment options and patient management strategies is difficult. In this review, we investigated the clinical outcomes of initial TSS in patients with Cushing's disease based on definitions of and assessments for remission and recurrence. We systematically searched PubMed and identified 44 studies with clear definitions of remission and recurrence. When data were available, additional analyses by time of remission, tumor size, duration of follow-up, surgical experience, year of study publication and adverse events related to surgery were performed. Data from a total of 6400 patients who received microscopic TSS were extracted and analyzed. A variety of definitions of remission and recurrence of Cushing's disease after initial microscopic TSS was used, giving broad ranges of remission (42.0-96.6%; median, 77.9%) and recurrence (0-47.4%; median, 11.5%). Better remission and recurrence outcomes were achieved for microadenomas vs macroadenomas; however, no correlations were found with other parameters, other than improved safety with longer surgical experience. The variety of methodologies used in clinical evaluation of TSS for Cushing's disease strongly support the call for standardization and optimization of studies to inform clinical practice and maximize patient outcomes. Clinically significant rates of failure of initial TSS highlight the need for effective second-line treatments. © 2015 European Society of Endocrinology.

1980-01-01

The activities of the Point-Focusing Thermal and Electric Applications (PETEA) project for the fiscal year 1979 are summarized. The main thrust of the PFTEA Project, the small community solar thermal power experiment, was completed. Concept definition studies included a small central receiver approach, a point-focusing distributed receiver system with central power generation, and a point-focusing distributed receiver concept with distributed power generation. The first experiment in the Isolated Application Series was initiated. Planning for the third engineering experiment series, which addresses the industrial market sector, was also initiated. In addition to the experiment-related activities, several contracts to industry were let and studies were conducted to explore the market potential for point-focusing distributed receiver (PFDR) systems. System analysis studies were completed that looked at PFDR technology relative to other small power system technology candidates for the utility market sector.

Investigation of solar active regions at high resolution by balloon flights of the solar optical universal polarimeter, definition phase

Tarbell, Theodore D.; Topka, Kenneth P.

1992-01-01

The definition phase of a scientific study of active regions on the sun by balloon flight of a former Spacelab instrument, the Solar Optical Universal Polarimeter (SOUP) is described. SOUP is an optical telescope with image stabilization, tunable filter and various cameras. After the flight phase of the program was cancelled due to budgetary problems, scientific and engineering studies relevant to future balloon experiments of this type were completed. High resolution observations of the sun were obtained using SOUP components at the Swedish Solar Observatory in the Canary Islands. These were analyzed and published in studies of solar magnetic fields and active regions. In addition, testing of low-voltage piezoelectric transducers was performed, which showed they were appropriate for use in image stabilization on a balloon.

Impact of planetary boundary layer turbulence on model climate and tracer transport

NASA Astrophysics Data System (ADS)

McGrath-Spangler, E. L.; Molod, A.; Ott, L. E.; Pawson, S.

2014-12-01

Planetary boundary layer (PBL) processes are important for weather, climate, and tracer transport and concentration. One measure of the strength of these processes is the PBL depth. However, no single PBL depth definition exists and several studies have found that the estimated depth can vary substantially based on the definition used. In the Goddard Earth Observing System (GEOS-5) atmospheric general circulation model, the PBL depth is particularly important because it is used to calculate the turbulent length scale that is used in the estimation of turbulent mixing. This study analyzes the impact of using three different PBL depth definitions in this calculation. Two definitions are based on the scalar eddy diffusion coefficient and the third is based on the bulk Richardson number. Over land, the bulk Richardson number definition estimates shallower nocturnal PBLs than the other estimates while over water this definition generally produces deeper PBLs. The near surface wind velocity, temperature, and specific humidity responses to the change in turbulence are spatially and temporally heterogeneous, resulting in changes to tracer transport and concentrations. Near surface wind speed increases in the bulk Richardson number experiment cause Saharan dust increases on the order of 1 × 10-4 kg m-2 downwind over the Atlantic Ocean. Carbon monoxide (CO) surface concentrations are modified over Africa during boreal summer, producing differences on the order of 20 ppb, due to the model's treatment of emissions from biomass burning. While differences in carbon dioxide (CO2) are small in the time mean, instantaneous differences are on the order of 10 ppm and these are especially prevalent at high latitude during boreal winter. Understanding the sensitivity of trace gas and aerosol concentration estimates to PBL depth is important for studies seeking to calculate surface fluxes based on near-surface concentrations and to studies projecting future concentrations.

Formal semantic specifications as implementation blueprints for real-time programming languages

NASA Technical Reports Server (NTRS)

Feyock, S.

1981-01-01

Formal definitions of language and system semantics provide highly desirable checks on the correctness of implementations of programming languages and their runtime support systems. If these definitions can give concrete guidance to the implementor, major increases in implementation accuracy and decreases in implementation effort can be achieved. It is shown that of the wide variety of available methods the Hgraph (hypergraph) definitional technique (Pratt, 1975), is best suited to serve as such an implementation blueprint. A discussion and example of the Hgraph technique is presented, as well as an overview of the growing body of implementation experience of real-time languages based on Hgraph semantic definitions.

Investigating the Role of Assessment Method on Reports of Déjà Vu and Tip-of-the-Tongue States during Standard Recognition Tests

PubMed Central

Jersakova, Radka; Moulin, Chris J. A.

2016-01-01

Déjà vu and tip-of-the-tongue (TOT) are retrieval-related subjective experiences whose study relies on participant self-report. In four experiments (ns = 224, 273, 123 and 154), we explored the effect of questioning method on reported occurrence of déjà vu and TOT in experimental settings. All participants carried out a continuous recognition task, which was not expected to induce déjà vu or TOT, but were asked about their experiences of these subjective states. When presented with contemporary definitions, between 32% and 58% of participants nonetheless reported experiencing déjà vu or TOT. Changing the definition of déjà vu or asking participants to bring to mind a real-life instance of déjà vu or TOT before completing the recognition task had no impact on reporting rates. However, there was an indication that changing the method of requesting subjective reports impacted reporting of both experiences. More specifically, moving from the commonly used retrospective questioning (e.g. “Have you experienced déjà vu?”) to free report instructions (e.g. “Indicate whenever you experience déjà vu.”) reduced the total number of reported déjà vu and TOT occurrences. We suggest that research on subjective experiences should move toward free report assessments. Such a shift would potentially reduce the presence of false alarms in experimental work, thereby reducing the overestimation of subjective experiences prevalent in this area of research.

On the relation between feeling of knowing and lexical decision: persistent subthreshold activation or topic familiarity?

PubMed

Connor, L T; Balota, D A; Neely, J H

1992-05-01

Experiment 1 replicated Yaniv and Meyer's (1987) finding that lexical decision and episodic recognition performance was better for words previously yielding high-accessibility levels (a combination of feeling-of-knowing and tip-of-the-tongue ratings) in comparison with those yielding low-accessibility levels in a rare word definition task. Experiment 2 yielded the same pattern even though lexical decisions preceded accessibility estimates by a full week. Experiment 3 dismissed the possibility that the Experiment 2 results may have been due to a long-term influence from the lexical decision task to the rare word judgment task. These results support a model in which Ss (a) retrieve topic familiarity information in making accessibility estimates in the rare word definition task and (b) use this information to modulate lexical decision performance.

A Definition of STS Accommodations for Attached Payloads

1983-01-01

An input to a study conducted to define a set of carrier avionics for supporting large structures experiments attached to the Space Shuttle Orbiter is reported. The "baseline" Orbier interface used in developing the avionics concept for the Space Technology Experiments Platform, STEP, which Langley Research Center has proposed for supporting experiments of this sort is defined. Primarily, flight operations capabilities and considerations and the avionics systems capabilities that are available to a payload as a "mixed cargo" user of the Space Transportation System are addressed. Ground operations for payload integration at Kennedy Space Center, and ground operations for payload support during the mission are also discussed.

Mourning is a natural response to a loss and a condition which most people experience several times during their lives. Most individuals adjust adequately to the loss of a relative, neverthless, a small but noteworthy proportion of bereaved individuals experience a syndrome of prolonged psychological distress in relation to bereavement. Prolonged distress and disability in connection with bereavement has been termed Complicated Grief (CG) or Prolonged Grief Disorder (PGD). The purpose of this paper is to analyze the literature on loss and mourning making a review of the main studies published between 1993 and 2013, identified through a search conducted on Medline/PubMed, in order to describe the epidemiological and clinical aspects of "normal" grief and "complicated" grief, pointing out the path of the clinical definition of PGD and proposed diagnostic criteria for inclusion in the next edition of the Diagnostic and Statistic Manual of Mental Disorders, Fifth edition (DSM-5). The two main diagnostic systems proposed by Horowitz and Prigerson are also compared.

Workplace harassment: a test of definitional criteria derived from an analysis of research definitions and Canadian social definitions.

PubMed

Claybourn, Marvin; Spinner, Barry; Malcom, Kathryn

2014-01-01

Public awareness of the occurrence and effects of workplace harassment continues to grow. However, despite increasing awareness, ambiguity remains about how harassment is defined and, consequently, how to determine whether a questionable situation should be judged as harassment. For this research we reviewed definitions of workplace harassment and identified four elements that were frequently included as criteria for making judgments of whether harassment had occurred (i.e., repetition, intent, perceived intent, consequences). In two separate studies, fictional scenarios were used to evaluate the extent to which participants' judgments about harassment were affected by the presence or absence of the four elements. Ratings of the scenarios provided by student participants (study one; N=160) and a convenience sample of community participants (study two; N=292) with varying levels of work experience and diverse professional backgrounds were analysed. According to our results the four elements significantly influenced participants' judgments of harassment. The intent of the harasser had the strongest and most consistent effect on harassment judgements and whether the behaviour was repeated had the weakest and least consistent effect. In addition to the unique effects of the individual elements, significant interactions between the elements emerged and suggest that harassment judgements depend on the interplay of a variety of factors. Though the results of these studies add to the growing body of research that focuses on defining workplace harassment, they also highlight the need for additional research in the area.

Shopping versus Nature? An Exploratory Study of Everyday Experiences.

PubMed

Craig, Tony P; Fischer, Anke; Lorenzo-Arribas, Altea

2018-01-01

Although a growing volume of empirical research shows that being in nature is important for human wellbeing, the definition of what constitutes an 'experience in nature,' and how this is different from other types of experiences, is very often left implied. In this paper we contrast everyday experiences involving nature with a category of everyday experience in which most people regularly partake. We present an exploratory study in which people ( N = 357) were explicitly asked to describe a memory they had of an everyday 'experience which involved nature,' as well as an everyday 'experience which involved shopping.' The open-ended responses to these questions were analyzed both quantitatively and qualitatively. Nature experiences were generally found to be more positive than shopping experiences, and they were more likely to be rated as 'peaceful' and 'active' compared to shopping experiences. Follow-up analyses indicate a significant interaction between experience category (nature or shopping), and the relationship between connectedness to nature and the amount of pleasure associated with that experience: The more strongly connected to nature a respondent was, the larger the disparity between the pleasantness of the shopping experience and that of the experience in nature tended to be.

Redefining Authentic Research Experiences in Introductory Biology Laboratories and Barriers to Their Implementation

PubMed Central

Spell, Rachelle M.; Guinan, Judith A.; Miller, Kristen R.; Beck, Christopher W.

2014-01-01

Incorporating authentic research experiences in introductory biology laboratory classes would greatly expand the number of students exposed to the excitement of discovery and the rigor of the scientific process. However, the essential components of an authentic research experience and the barriers to their implementation in laboratory classes are poorly defined. To guide future reform efforts in this area, we conducted a national survey of biology faculty members to determine 1) their definitions of authentic research experiences in laboratory classes, 2) the extent of authentic research experiences currently experienced in their laboratory classes, and 3) the barriers that prevent incorporation of authentic research experiences into these classes. Strikingly, the definitions of authentic research experiences differ among faculty members and tend to emphasize either the scientific process or the discovery of previously unknown data. The low level of authentic research experiences in introductory biology labs suggests that more development and support is needed to increase undergraduate exposure to research experiences. Faculty members did not cite several barriers commonly assumed to impair pedagogical reform; however, their responses suggest that expanded support for development of research experiences in laboratory classes could address the most common barrier.

The revised transliminality scale: reliability and validity data from a Rasch top-down purification procedure.

PubMed

Lange, R; Thalbourne, M A; Houran, J; Storm, L

2000-12-01

The concept of transliminality ("a hypothesized tendency for psychological material to cross thresholds into or out of consciousness") was anticipated by William James (1902/1982), but it was only recently given an empirical definition by Thalbourne in terms of a 29-item Transliminality Scale. This article presents the 17-item Revised Transliminality Scale (or RTS) that corrects age and gender biases, is unidimensional by a Rasch criterion, and has a reliability of.82. The scale defines a probabilistic hierarchy of items that address magical ideation, mystical experience, absorption, hyperaesthesia, manic experience, dream interpretation, and fantasy proneness. These findings validate the suggestions by James and Thalbourne that some mental phenomena share a common underlying dimension with selected sensory experiences (such being overwhelmed by smells, bright lights, sights, and sounds). Low scores on transliminality remain correlated with "tough mindedness" in on Cattell 16PF test, as well as "self-control" and "rule consciousness," whereas high scores are associated with "abstractedness" and an "openness to change" on that test. An independent validation study confirmed the predictions implied by our definition of transliminality. Implications for test construction are discussed. Copyright 2000 Academic Press.

Automated identification of social interaction criteria in Drosophila melanogaster.

PubMed

Schneider, J; Levine, J D

2014-10-01

The study of social behaviour within groups has relied on fixed definitions of an 'interaction'. Criteria used in these definitions often involve a subjectively defined cut-off value for proximity, orientation and time (e.g. courtship, aggression and social interaction networks) and the same numerical values for these criteria are applied to all of the treatment groups within an experiment. One universal definition of an interaction could misidentify interactions within groups that differ in life histories, study treatments and/or genetic mutations. Here, we present an automated method for determining the values of interaction criteria using a pre-defined rule set rather than pre-defined values. We use this approach and show changing social behaviours in different manipulations of Drosophila melanogaster. We also show that chemosensory cues are an important modality of social spacing and interaction. This method will allow a more robust analysis of the properties of interacting groups, while helping us understand how specific groups regulate their social interaction space. © 2014 The Author(s) Published by the Royal Society.

Dissociation From a Cross-Cultural Perspective: Implications of Studies in Brazil.

PubMed

Maraldi, Everton de Oliveira; Krippner, Stanley; Barros, Maria Cristina Monteiro; Cunha, Alexandre

2017-07-01

A major issue in the study of dissociation concerns the cross-cultural validity of definitions and measurements used to identify and classify dissociative disorders. There is also extensive debate on the etiological factors underlying dissociative experiences. Cross-cultural research is essential to elucidate these issues, particularly regarding evidence obtained from countries in which the study of dissociation is still in its infancy. The aim of this article was to discuss Brazilian research on the topic of dissociation, highlighting its contributions for the understanding of dissociative experiences in nonclinical populations and for the validity and relevance of dissociative disorders in the contexts of psychiatry, psychology, and psychotherapy. We also consider the ways in which dissociative experiences are assimilated by Brazilian culture and religious expressions, and the implications of Brazilian studies for the sociocultural investigation of dissociation. We conclude by addressing the limitations of these studies and potential areas for future research.

Definition of experiments and instruments for a communication/navigation research laboratory. Volume 1: Executive summary

NASA Technical Reports Server (NTRS)

1972-01-01

This study was undertaken to develop conceptual designs for a manned, space shuttle sortie mission laboratory capable of supporting a wide variety of experiments in conjunction with communications and navigation research. This space/laboratory would be one in which man may effectively increase experiment efficiency by certain observations, modifications, setup, calibration, and limited maintenance steps. In addition, man may monitor experiment progress and perform preliminary data evaluation to verify proper equipment functioning and may terminate or redirect experiments to obtain the most desirable end results. The flexibility and unique capabilities of man as an experimenter in such a laboratory will add greatly to the simplification of space experiments and this provides the basis for commonality in many of the supportive subsystems, thus reaping the benefits of reusability and reduced experiment costs.

Advanced Cosmic Ray Composition Experiment for Space Station (ACCESS)

NASA Technical Reports Server (NTRS)

Wilson, Thomas L.; Wefel, John P.

1999-01-01

In 1994 the first high-energy particle physics experiment for the Space Station, the Alpha Magnetic Spectrometer (AMS), was selected by NASA's Administrator as a joint collaboration with the U.S. Department of Energy (DOE). The AMS program was chartered to place a magnetic spectrometer in Earth orbit and search for cosmic antimatter. A natural consequence of this decision was that NASA would begin to explore cost-effective ways through which the design and implementation of AMS might benefit other promising payload experiments which were evolving from the Office of Space Science. The first such experiment to come forward was ACCESS in 1996. It was proposed as a new mission concept in space physics to place a cosmic-ray experiment of weight, volume, and geometry similar to the AMS on the ISS, and replace the latter as its successor when the AMS is returned to Earth. This was to be an extension of NASA's sub-orbital balloon program, with balloon payloads serving as the precursor flights and heritage for ACCESS. The balloon programs have always been a cost-effective NASA resource since the particle physics instrumentation for balloon and space applications are directly related. The next step was to expand the process, pooling together expertise from various NASA centers and universities while opening up definition of the ACCESS science goals to the international community through the standard practice of peer-review. This process is still on-going and the Accommodation Study presented here will discuss the baseline definition of ACCESS as we understand it today. Further detail on the history, scope, and background of the study is provided in Appendix A.

Free-decay time-domain modal identification for large space structures

NASA Technical Reports Server (NTRS)

Kim, Hyoung M.; Vanhorn, David A.; Doiron, Harold H.

1992-01-01

Concept definition studies for the Modal Identification Experiment (MIE), a proposed space flight experiment for the Space Station Freedom (SSF), have demonstrated advantages and compatibility of free-decay time-domain modal identification techniques with the on-orbit operational constraints of large space structures. Since practical experience with modal identification using actual free-decay responses of large space structures is very limited, several numerical and test data reduction studies were conducted. Major issues and solutions were addressed, including closely-spaced modes, wide frequency range of interest, data acquisition errors, sampling delay, excitation limitations, nonlinearities, and unknown disturbances during free-decay data acquisition. The data processing strategies developed in these studies were applied to numerical simulations of the MIE, test data from a deployable truss, and launch vehicle flight data. Results of these studies indicate free-decay time-domain modal identification methods can provide accurate modal parameters necessary to characterize the structural dynamics of large space structures.

Research on nursing practice. Stress.

PubMed

Lyon, B L; Werner, J S

1987-01-01

Clearly, there is not agreement among nurse researchers regarding a definitional orientation to stress that best fits nursing's orientation to human experiences. Varying theoretical orientations are used to explain stress or stress-related phenomena, for example, stress as a stimulus, stress as a response, and stress as a transaction. The studies are fairly evenly distributed among the four definitional categories. The various approaches do not represent expanding theoretical explanations of stress, but rather are incompatible approaches to explaining stress. More disconcerting than the lack of direction in research efforts, however, is that all too commonly the measurement of the variables and the methodology were not "linked" or consistent with the theoretical framework. For the most part the research efforts reviewed fell short of theory testing. Even for those studies that were designed to contribute to theory development, it was rare to find research reports that included implications regarding theory in the discussion sections. Additionally, discussion sections of the reports typically did not identify alternative explanations for the findings. Quasi-experimental, ex post facto, and causal comparative studies typically were flawed with validity problems. If nursing is to strengthen its contribution to knowledge in the area of stress, more emphasis will need to be placed on congruence between design and measurement, and on issues of statistical rigor, validity, and reliability. Although some might argue that it is too early to expect a coalescing of definitional orientations, it is important to point out that considerable confusion regarding stress phenomena results from a nonsystematic or nondeliberative mixture of incompatible orientations to or definitions of stress. It is little wonder that the vast number of opinion articles that appear in the nursing literature include varied definitions of stress, often making conflicting recommendations regarding the nursing assessment of stress and nursing intervention strategies to assist a person in stress management efforts.

[Phenomenology and phenomenological method: their usefulness for nursing knowledge and practice].

PubMed

Vellone, E; Sinapi, N; Rastelli, D

2000-01-01

Phenomenology is a thought movement the main aim of which is to study human fenomena as they are experienced and lived. Key concepts of phenomenology are: the study of lived experience and subjectivity of human beings, the intentionality of consciousness, perception and interpretation. Phenomenological research method has nine steps: definition of the research topic; superficial literature searching; sample selection; gathering of lived experiences; analysis of lived experiences; written synthesis of lived experiences; validation of written synthesis; deep literature searching; writing of the scientific document. Phenomenology and phenomenological method are useful for nursing either to develop knowledge or to guide practice. Qualitative-phenomenological and quantitative-positivistic research are complementary: the first one guides clinicians towards a person-centered approach, the second one allows the manipulation of phenomena which can damage health, worsen illness or decrease the quality of life of people who rely on nursing care.

Complex negotiations: the lived experience of enacting agency after a stroke.

PubMed

Bergström, Aileen L; Eriksson, Gunilla; Asaba, Eric; Erikson, Anette; Tham, Kerstin

2015-01-01

This qualitative, longitudinal, descriptive study aimed to understand the lived experience of enacting agency, and to describe the phenomenon of agency and the meaning structure of the phenomenon during the year after a stroke. Agency is defined as making things happen in everyday life through one's actions. This study followed six persons (three men and three women, ages 63 to 89), interviewed on four separate occasions. Interview data were analysed using the Empirical Phenomenological Psychological method. The main findings showed that the participants experienced enacting agency in their everyday lives after stroke as negotiating different characteristics over a span of time, a range of difficulty, and in a number of activities, making these negotiations complex. The four characteristics described how the participants made things happen in their everyday lives through managing their disrupted bodies, taking into account their past and envisioning their futures, dealing with the world outside themselves, and negotiating through internal dialogues. This empirical evidence regarding negotiations challenges traditional definitions of agency and a new definition of agency is proposed. Understanding clients' complex negotiations and offering innovative solutions to train in real-life situations may help in the process of enabling occupations after a stroke.

From 1982 to 2001, 10 patients (6 males, 4 females) with EMPHN were treated in our institution. Of nine patients treated at initial diagnosis, all received definitive radiotherapy. One patient treated at relapse underwent surgical resection followed by post-operative radiotherapy. The median age at diagnosis was 55 years (range 35-84 years). The disease was most frequently localized in the paranasal sinuses (50%). All nine patients who received definitive radiotherapy at a dose of 40-50 Gy achieved a complete response. The median follow up period was 29 months (range 7-67 months). Four patients (40%) relapsed, three have died of their disease. Two patients (20%) with paranasal sinus disease subsequently relapsed with multiple myeloma at 10 months and 24 months, respectively. Our results indicate that treatment of EMPHN with radiotherapy achieves excellent rates of local control. The relapse rate in neck nodes of 10% does not justify elective irradiation of the uninvolved neck.

Helmet-Mounted Display Design Guide

Newman, Richard L.; Greeley, Kevin W.

Helmet Mounted Displays (HMDs) present flight, navigation, and weapon information in the pilot's line of sight. The HMD was developed to allow the pilot to retain aircraft and weapon information while looking off boresight. This document reviews current state of the art in HMDs and presents a design guide for the HMD engineer in identifying several critical HMD issues: symbol stabilization, inadequate definitions, undefined symbol drive laws, helmet considerations, and Field Of View (FOV) vs. resolution tradeoff requirements. In particular, display latency is a key issue for HMDs. In addition to requiring further experimental studies, it impacts the definition and control law issues. Symbol stabilization is also critical. In the case of the Apache helicopter, the lack of compensation for pilot head motion creates excessive workload during hovering and Nap Of the Earth (NOE) flight. This translates into excessive training requirements. There is no agreed upon set of definitions or descriptions for how HMD symbols are driven to compensate for pilot head motion. A set of definitions is proposed to address this. There are several specific areas where simulation and flight experiments are needed: development of hover and NOE symbologies which compensate for pilot head movement; display latency and sampling, and the tradeoff between FOV, sensor resolution and symbology.

Lack of consensus on the definition of mental health has implications for research, policy and practice. This study aims to start an international, interdisciplinary and inclusive dialogue to answer the question: What are the core concepts of mental health? 50 people with expertise in the field of mental health from 8 countries completed an online survey. They identified the extent to which 4 current definitions were adequate and what the core concepts of mental health were. A qualitative thematic analysis was conducted of their responses. The results were validated at a consensus meeting of 58 clinicians, researchers and people with lived experience. 46% of respondents rated the Public Health Agency of Canada (PHAC, 2006) definition as the most preferred, 30% stated that none of the 4 definitions were satisfactory and only 20% said the WHO (2001) definition was their preferred choice. The least preferred definition of mental health was the general definition of health adapted from Huber et al (2011). The core concepts of mental health were highly varied and reflected different processes people used to answer the question. These processes included the overarching perspective or point of reference of respondents (positionality), the frameworks used to describe the core concepts (paradigms, theories and models), and the way social and environmental factors were considered to act. The core concepts of mental health identified were mainly individual and functional, in that they related to the ability or capacity of a person to effectively deal with or change his/her environment. A preliminary model for the processes used to conceptualise mental health is presented. Answers to the question, 'What are the core concepts of mental health?' are highly dependent on the empirical frame used. Understanding these empirical frames is key to developing a useful consensus definition for diverse populations. Published by the BMJ Publishing Group Limited.

Background Many health care systems now allow patients to access their electronic health record (EHR) notes online through patient portals. Medical jargon in EHR notes can confuse patients, which may interfere with potential benefits of patient access to EHR notes. Objective The aim of this study was to develop and evaluate the usability and content quality of NoteAid, a Web-based natural language processing system that links medical terms in EHR notes to lay definitions, that is, definitions easily understood by lay people. Methods NoteAid incorporates two core components: CoDeMed, a lexical resource of lay definitions for medical terms, and MedLink, a computational unit that links medical terms to lay definitions. We developed innovative computational methods, including an adapted distant supervision algorithm to prioritize medical terms important for EHR comprehension to facilitate the effort of building CoDeMed. Ten physician domain experts evaluated the user interface and content quality of NoteAid. The evaluation protocol included a cognitive walkthrough session and a postsession questionnaire. Physician feedback sessions were audio-recorded. We used standard content analysis methods to analyze qualitative data from these sessions. Results Physician feedback was mixed. Positive feedback on NoteAid included (1) Easy to use, (2) Good visual display, (3) Satisfactory system speed, and (4) Adequate lay definitions. Opportunities for improvement arising from evaluation sessions and feedback included (1) improving the display of definitions for partially matched terms, (2) including more medical terms in CoDeMed, (3) improving the handling of terms whose definitions vary depending on different contexts, and (4) standardizing the scope of definitions for medicines. On the basis of these results, we have improved NoteAid’s user interface and a number of definitions, and added 4502 more definitions in CoDeMed. Conclusions Physician evaluation yielded useful feedback for content validation and refinement of this innovative tool that has the potential to improve patient EHR comprehension and experience using patient portals. Future ongoing work will develop algorithms to handle ambiguous medical terms and test and evaluate NoteAid with patients. PMID:29358159

The definition and role of quality of life in Germany's early assessment of drug benefit: a qualitative approach.

2016-02-01

In 2011, Germany introduced a new form of drug benefit assessment, linking reimbursement prices to drug benefit and making quality of life (QoL) one of the main benefit criteria. Thus, QoL outcomes co-determine drug prices in Germany. QoL has, however, not been defined in the regulations. This study analyzed the definition and role of QoL in Germany's drug benefit assessment. It serves as a case study on the complexity of QoL as a parameter of health technology and drug assessments, which have become mandatory in almost all industrialized countries. In a qualitative analysis, the publicly available dossiers (summaries), dossier evaluations, protocols of the oral hearings, the final resolutions of the Federal Joint Committee (G-BA) and its rationale of all benefit assessments completed by 2013 (n = 66) were processed. Additionally, quantitative data on the decision outcomes were collected. Only two decisions drew on QoL outcomes as "main justifications" for additional benefit. It was due to a lack of valid and statistically significant QoL results, a deficient presentation of QoL data, or differing understandings of QoL, that QoL benefit was not demonstrated in more than two cases. While manufacturers applied wider definitions of QoL, the assessment institutions questioned evidence if it was not reported with the help of validated QoL questionnaires or deviated from their definition of QoL. The German experience with QoL as a drug benefit criterion highlights the importance of a clear QoL definition and according methodological regulations.

Temporal variations in cancer pain intensity are highly prevalent, and are often difficult to manage. However, the phenomenon is not well understood: several definitions and approaches to classification and bedside assessment of cancer breakthrough pain (BTP) have been described. The present study is a systematic review of published literature on cancer BTP to answer the following questions: which terms and definitions have been used; are there validated assessment tools; which domains of BTP do the tools delineate, and which items do they contain; how have assessment tools been applied within clinical studies; and are there validated classification systems for BTP. A systematic search of the peer-reviewed literature was performed using five major databases. Of 375 titles and abstracts initially identified, 51 articles were examined in detail. Analysis of these publications indicates a range of overlapping but distinct definitions have been used to characterize BTP; 42 of the included papers presented one or more ways of classifying BTP; and while 10 tools to assess patients' experience of BTP were identified, only 2 have been partially validated. We conclude that there is no widely accepted definition, classification system or well-validated assessment tool for cancer-related breakthrough pain, but there is strong concurrence on most of its key attributes. With further work in this area, an internationally agreed upon definition and classification system for cancer-related breakthrough pain, and a standard approach on how to measure it, hold the promise to improve patient care and support research in this poor-prognosis cancer pain syndrome.

Engineering students at typically invisible transition points: A focus on admissions and the sophomore year

NASA Astrophysics Data System (ADS)

Holloway, Elizabeth M.

As of 2012, women are approximately 19% of all engineering undergraduate students nationally (American Society for Engineering Education, 2012). Women's representation in engineering has not changed significantly over the last 20 years, despite increased attention, increased funding, and increased programmatic activities intended to encourage more women to become engineers. Research around the world continues to seek identification of the reasons for the underrepresentation of women in engineering. This prior work has focused primarily on two broad areas: recruiting, that is, preparation, socialization, exposure, and experiences prior to college; and retention, that is, experiences in higher education. Retention studies and programmatic responses to those studies mostly have been confined to the collegiate first year, a time of historically high attrition. Little attention has been paid to the university admissions process, one of the gateways to engineering studies. Little attention also has been paid to the experiences of college sophomores, whose attrition rates approach those of first-year college students. The first section of this dissertation presents a statistical analysis that indicated a bias in favor of men in the admission process. Success factor modeling suggested a different set of admission criteria could mitigate this bias. After recommendations to change admission criteria were implemented, the percent of female enrollment in engineering increased and statistical analysis confirmed that bias was substantially neutralized. The second section of this dissertation presents three frameworks for understanding how sophomores may be defined. The processes of conceptualizing and operationalizing what it means to be a sophomore impact the types of issues that can be investigated about student attrition, the findings that result from those investigations, and the ability to make cross institutional or programmatic comparisons using a clearly stated definition. Three definitions for classifying a sophomore--cohort, credits, and curriculum--are presented. The implications of each are discussed relative to the overall population but also specifically to women. All three retention methodologies were based on continued enrollment, with results disaggregated by gender. When analyzing retention data, the definition of a sophomore is an important choice as different definitions may or seem to provide different results. The cohort framework, for example, showed a higher percentage of students retained to their second year than to their third year. In contrast, a credit framework showed a higher percentage of students moving to a junior classification than to a sophomore classification. Because the literature review indicates that very little work has been done specifically on the sophomore engineer and most discussions about the sophomore year do not clearly state which sophomore framework is being applied to the research, this portion of the dissertation is a much needed step in clarifying the underlying bases whereby claims about retention are made. The third section of this dissertation is a study of sophomores' experiences in the engineering disciplines using the cohort definition of a sophomore. The cohort definition is used in this section to focus on the socio-cultural aspects of the second year in college. With a historical emphasis on and increasing positive results of increasing first-year retention, attention is now turning to the sophomore year. Understanding sophomore students' experiences in engineering may assist in developing strategies to reduce attrition and may assist in managing the culture in such a way that makes it more attractive to women and others who are underrepresented. The Sophomore Experiences Survey (Schreiner, 2010) was administered at one institution to the sophomore engineering cohort. Statistical comparisons of results between engineers and sophomores nationally showed more areas of similarity than differences, although the differences indicated that engineering sophomores were less engaged in their learning and less engaged with faculty and advisors. Sophomore engineering women were much more likely than men to be involved in engineering peer mentoring or leadership programs. Multiple regression analysis indicated that the most significant predictor of student satisfaction was satisfaction with peers on campus. The most significant predictor of intention to persist and intention to graduate was surety of major choice. However, there were differences in the most significant predictors when looking at men and women separately. Predictors of success outcomes for engineering sophomores point to the interconnectedness of experiences with faculty, advisors, and peers with individual student traits, characteristics, and preferences, with individual aspects acting as mediating and moderating factors. The overarching results of this research project offer frameworks through which change in the engineering education process can lead to greater participation by women in the engineering field, and increased retention rates for all engineering students.

Purpose To examine if there was spatial misclassification in exposure to neighborhood noise complaints among a sample of low-income housing residents in New York City, comparing home-based spatial buffers and Global Positioning Systems (GPS) daily path buffers. Methods Data came from the community-based NYC Low-Income Housing, Neighborhoods and Health Study, where GPS tracking of the sample was conducted for a week (analytic n=102). We created a GPS daily path buffer (a buffering zone drawn around GPS tracks) of 200-meters and 400-meters. We also used home-based buffers of 200-meters and 400-meters. Using these “neighborhoods” (or exposure areas) we calculated neighborhood exposure to noisy events from 311 complaints data (analytic n=143,967). Friedman tests (to compare overall differences in neighborhood definitions) were applied. Results There were differences in neighborhood noise complaints according to the selected neighborhood definitions (p<0.05). For example, the mean neighborhood noise complaint count was 1196 per square kilometer for the 400-meter home-based and 812 per square kilometer for the 400-meter activity space buffer, illustrating how neighborhood definition influences the estimates of exposure to neighborhood noise complaints. Conclusions These analyses suggest that, whenever appropriate, GPS neighborhood definitions can be used in spatial epidemiology research in spatially mobile populations to understand people's lived experience.

Background Research suggests that the lived experience of inadequate sanitation may contribute to poor health outcomes above and beyond pathogen exposure, particularly among women. The goal of this research was to understand women’s lived experiences of sanitation by documenting their urination-related, defecation-related and menstruation-related concerns, to use findings to develop a definition of sanitation insecurity among women in low-income settings and to develop a conceptual model to explain the factors that contribute to their experiences, including potential behavioural and health consequences. Methods We conducted 69 Free-List Interviews and eight focus group discussions in a rural population in Odisha, India to identify women’s sanitation concerns and to build an understanding of sanitation insecurity. Findings We found that women at different life stages in rural Odisha, India have a multitude of unaddressed urination, defecation and menstruation concerns. Concerns fell into four domains: the sociocultural context, the physical environment, the social environment and personal constraints. These varied by season, time of day, life stage and toilet ownership, and were linked with an array of adaptations (ie, suppression, withholding food and water) and consequences (ie, scolding, shame, fear). Our derived definition and conceptual model of sanitation insecurity reflect these four domains. Discussion To sincerely address women’s sanitation needs, our findings indicate that more is needed than facilities that change the physical environment alone. Efforts to enable urinating, defecating and managing menstruation independently, comfortably, safely, hygienically, privately, healthily, with dignity and as needed require transformative approaches that also address the gendered, sociocultural and social environments that impact women despite facility access. This research lays the groundwork for future sanitation studies to validate or refine the proposed definition and to assess women’s sanitation insecurity, even among those who have latrines, to determine what may be needed to improve women’s sanitation circumstances.

A typical Advanced Technology Laboratory mission flight plan was developed and used as a guideline for the identification of a number of experiment considerations. The experiment logistics beginning with sample preparation and ending with sample analysis are then overlaid on the mission in order to have a complete picture of the design requirements. The results of this preliminary design study fall into two categories. First specific preliminary designs of experiment hardware which is adaptable to a variety of mission requirements. Second, identification of those mission considerations which affect hardware design and will require further definition prior to final design. Finally, a program plan is presented which will provide the necessary experiment hardware in a realistic time period to match the planned shuttle flights. A bibliography of all material reviewed and consulted but not specifically referenced is provided.

Why do people with delusions fail to choose more realistic explanations for their experiences? An empirical investigation.

2004-08-01

Delusions can be viewed as explanations of experiences,. By definition, the experiences are insufficient to merit the delusional explanations. So why have delusions been accepted rather than more realistic explanations? The authors report a study of alternative explanations in 100 individuals with delusions. Patients were assessed on the following criteria: symptom measures, the evidence for the delusions, the availability of alternative explanations, reasoning, and self-esteem. Three quarters of the patients did not report any alternative explanation for the experiences on which the delusions were based. These patients reported significantly more internal anomalous experiences and had a more hasty reasoning style than patients who did have alternative explanations available. Having doubt in a delusion, without an alternative explanation, was associated with lower self-esteem. Clinicians will need to develop plausible and compelling alternative accounts of experience in interventions rather than merely challenge patients' delusional beliefs.

This study investigated whether attitudinal variables, such as benevolent and hostile sexism toward men and women, female rape myth acceptance, and tolerance of sexual harassment are related to women labeling their sexual assault experiences as rape. In a sample of 276 female college students, 71 (25.7%) reported at least one experience that met the operational definition of rape, although only 46.5% of those women labeled the experience "rape." Benevolent sexism, tolerance of sexual harassment, and rape myth acceptance, but not hostile sexism, significantly predicted labeling of previous sexual assault experiences by the victims. Specifically, those with more benevolent sexist attitudes toward both men and women, greater rape myth acceptance, and more tolerant attitudes of sexual harassment were less likely to label their past sexual assault experience as rape. The results are discussed for their clinical and theoretical implications.

A sizable minority of women report lifetime sexual behavior with both men and women. In the present study, a multinational sample of women who reported genital contact with at least one man and one woman in their lifetime (N = 2,751) were asked to provide their behavioral definitions of "having sex with a woman" and "having sex with a man." Replicating previous research, participants were asked "Would you say you 'had sex' with a woman/man if the most intimate behavior you engaged in with her/him was …" followed by a list of behaviors that differed based on the hypothetical partner gender. While most participants indicated that they would consider "having had sex" if they engaged in a variety of behaviors, behaviors involving genital contact were most often included within the participants' definitions of having sex, regardless of partner gender. The percentage of behaviors included in the participants' definitions of having sex with a woman (M = 59.40%, SD = 20.77%) was higher than the percentage of behaviors included in their definition of having sex with a man (M = 37.26%, SD = 28.97%). Broadening our understanding of "having sex" for individuals with diverse sexual experiences may have important implications for clinicians and researchers.

Case definition terminology for paratuberculosis (Johne's disease).

2017-11-09

Paratuberculosis (Johne's disease) is an economically significant condition caused by Mycobacterium avium subsp. paratuberculosis. However, difficulties in diagnosis and classification of individual animals with the condition have hampered research and impeded efforts to halt its progressive spread in the global livestock industry. Descriptive terms applied to individual animals and herds such as exposed, infected, diseased, clinical, sub-clinical, infectious and resistant need to be defined so that they can be incorporated consistently into well-understood and reproducible case definitions. These allow for consistent classification of individuals in a population for the purposes of analysis based on accurate counts. The outputs might include the incidence of cases, frequency distributions of the number of cases by age class or more sophisticated analyses involving statistical comparisons of immune responses in vaccine development studies, or gene frequencies or expression data from cases and controls in genomic investigations. It is necessary to have agreed definitions in order to be able to make valid comparisons and meta-analyses of experiments conducted over time by a given researcher, in different laboratories, by different researchers, and in different countries. In this paper, terms are applied systematically in an hierarchical flow chart to enable classification of individual animals. We propose descriptive terms for different stages in the pathogenesis of paratuberculosis to enable their use in different types of studies and to enable an independent assessment of the extent to which accepted definitions for stages of disease have been applied consistently in any given study. This will assist in the general interpretation of data between studies, and will facilitate future meta-analyses.

Defining what constitutes a resident care unit in nursing home research is both a conceptual and practical challenge. The aim of this paper is to provide evidence in support of a definition of care unit in nursing homes by demonstrating: (1) its feasibility for use in data collection, (2) the acceptability of aggregating individual responses to the unit level, and (3) the benefit of including unit level data in explanatory models. An observational study design was used. Research (project) managers, healthcare aides, care managers, nursing home administrators and directors of care from thirty-six nursing homes in the Canadian prairie provinces of Alberta, Saskatchewan and Manitoba provided data for the study. A definition of care unit was developed and applied in data collection and analyses. A debriefing session was held with research managers to investigate their experiences with using the care unit definition. In addition, survey responses from 1258 healthcare aides in 25 of the 36 nursing homes in the study, that had more than one care unit, were analyzed using a multi-level modeling approach. Trained field workers administered the Alberta Context Tool (ACT), a 58-item self-report survey reflecting 10 organizational context concepts, to healthcare aides using computer assisted personal interviews. To assess the appropriateness of obtaining unit level scores, we assessed aggregation statistics (ICC(1), ICC(2), η², and ω²), and to assess the value of using the definition of unit in explanatory models, we performed multi-level modeling. In 10 of the 36 nursing homes, the care unit definition developed was used to align the survey data (for analytic purposes) to specific care units as designated by our definition, from that reported by the facility administrator. The aggregation statistics supported aggregating the healthcare aide responses on the ACT to the realigned unit level. Findings from the multi-level modeling further supported unit level aggregation. A significantly higher percentage of variance was explained in the ACT concepts at the unit level compared to the individual and/or nursing home levels. The statistical results support the use of our definition of care unit in nursing home research in the Canadian prairie provinces. Beyond research convenience however, the results also support the resident unit as an important Clinical Microsystem to which future interventions designed to improve resident quality of care and staff (healthcare aide) worklife should be targeted.

What does quality of life refer to in bipolar disorders research? A systematic review of the construct's definition, usage and measurement.

2017-04-01

Quality of life (QoL) is increasingly investigated in bipolar disorders (BD) research, yet little attention has been paid to its optimal definition and measurement. This is a significant limitation, as the broader QoL literature recognises a number of divergent meanings and measurement tensions. The aim here was to advance understanding of QoL in BD by clarifying use of the construct in the existing literature and considering measurement implications. Thematic analysis techniques were used to interrogate articles identified via systematic search for (a) explicit discussion of QoL definitional/measurement issues, and (b) usage of the term QoL. A total of 275 articles were included in the analysis. A range of definitional and methodological issues confounding the study of QoL in BD were identified. While explicit definition of QoL proved rare, thematic analysis of usage of the construct revealed the concepts of functioning, health, subjective experience and wellbeing were thought to be relevant to QoL in BD. The review does not engage in top-down theory development. Our analysis was grounded in the empirical literature to support future theoretical work relevant to existing usage of QoL in BD. There was no evidence of a consensus definition of QoL in BD. A plurality of QoL definitions is not necessarily a flaw in the literature, but points to empirical and conceptual issues demanding attention. Awareness of the diversity of constructs associated with QoL will enable clinicians to better select treatments on the basis of specific QoL outcomes. A research agenda and provisional considerations for empirical research are outlined based on the present analyses. Copyright © 2017 Elsevier B.V. All rights reserved.

A Special Application of Absolute Value Techniques in Authentic Problem Solving

ERIC Educational Resources Information Center

Stupel, Moshe

2013-01-01

There are at least five different equivalent definitions of the absolute value concept. In instances where the task is an equation or inequality with only one or two absolute value expressions, it is a worthy educational experience for learners to solve the task using each one of the definitions. On the other hand, if more than two absolute value…

Issue Definition in Rights-Based Policy Focused on the Experiences of Individuals with Disabilities: An Examination of Canadian Parliamentary Discourse

We investigated whether children at the ages of two and three years understand that a speaker's use of the definite article specifies a referent that is in common ground between speaker and listener. An experimenter and a child engaged in joint actions in which the experimenter chose one of three similar objects of the same category to perform an…

Shopping versus Nature? An Exploratory Study of Everyday Experiences

PubMed Central

Craig, Tony P.; Fischer, Anke; Lorenzo-Arribas, Altea

2018-01-01

Although a growing volume of empirical research shows that being in nature is important for human wellbeing, the definition of what constitutes an ‘experience in nature,’ and how this is different from other types of experiences, is very often left implied. In this paper we contrast everyday experiences involving nature with a category of everyday experience in which most people regularly partake. We present an exploratory study in which people (N = 357) were explicitly asked to describe a memory they had of an everyday ‘experience which involved nature,’ as well as an everyday ‘experience which involved shopping.’ The open-ended responses to these questions were analyzed both quantitatively and qualitatively. Nature experiences were generally found to be more positive than shopping experiences, and they were more likely to be rated as ‘peaceful’ and ‘active’ compared to shopping experiences. Follow-up analyses indicate a significant interaction between experience category (nature or shopping), and the relationship between connectedness to nature and the amount of pleasure associated with that experience: The more strongly connected to nature a respondent was, the larger the disparity between the pleasantness of the shopping experience and that of the experience in nature tended to be.

Situational Context Affects Definiteness Preferences: Accommodation of Presuppositions

PubMed Central

Clifton, Charles

2013-01-01

Four experiments used self-paced reading and eyetracking to demonstrate that readers are, under some conditions, sensitive to the presuppositions of definite vs. indefinite DPs (determiner phrases). Reading was faster when the context stereotypically provided a single possible referent for a definite DP or multiple possible referents for an indefinite DP than when context and DP definiteness were mismatched. This finding goes beyond previous evidence that definite DPs are processed more rapidly than indefinite DPs when there is a unique or familiar referent in the context, showing that readers are sensitive to the semantics and pragmatics of (in)definiteness. However, the finding was obtained only when readers had to perform a simple arithmetic task between reading a sentence and seeing a question about it. The intervening task may have encouraged them to process the sentence more deeply in order to form a representation that would persist while doing the arithmetic. The methodological implications of this observation are discussed. PMID:22732029

Some potential blood flow experiments for space

NASA Technical Reports Server (NTRS)

Cokelet, G. R.; Meiselman, H. J.; Goldsmith, H. L.

1979-01-01

Blood is a colloidal suspension of cells, predominantly erythrocytes, (red cells) in an aqueous solution called plasma. Because the red cells are more dense than the plasma, and because they tend to aggregate, erythrocyte sedimentation can be significant when the shear stresses in flowing blood are small. This behavior, coupled with equipment restrictions, has prevented certain definitive fluid mechanical studies from being performed with blood in ground-based experiments. Among such experiments, which could be satisfactorily performed in a microgravity environment, are the following: (1) studies of blood flow in small tubes, to obtain pressure-flow rate relationships, to determine if increased red cell aggregation can be an aid to blood circulation, and to determine vessel entrance lengths, and (2) studies of blood flow through vessel junctions (bifurcations), to obtain information on cell distribution in downstream vessels of (arterial) bifurcations, and to test flow models of stratified convergent blood flows downstream from (venous) bifurcations.

2013-12-01

In the home hospice environment, issues arise every day presenting challenges to the safety, care, and quality of the dying experience. The literature pertaining to the safety challenges in this environment is limited. The study explored two research questions; 1) What types of patient safety incidents occur in the home hospice setting? 2) How many of these incidents are recognized by the hospice staff and/or the patient or caregiver as a patient safety incident? Video-recordings of hospice interdisciplinary team case conferences were reviewed and coded for patient safety incidents. Patient safety incidents were defined as any event or circumstance that could have resulted or did result in unnecessary harm to the patient or caregiver, or that could have resulted or did result in a negative impact on the quality of the dying experience for the patient. Codes for categories of patient safety incidents were based on the International Classification for Patient Safety. The setting for the study included two rural hospice programs in one Midwestern state in the United States. One hospice team had two separately functioning teams, the second hospice had three teams. 54 video-recordings were reviewed and coded. Patient safety incidents were identified that involved issues in clinical process, medications, falls, family or caregiving, procedural problems, documentation, psychosocial issues, administrative challenges and accidents. This study distinguishes categories of patient safety events that occur in home hospice care. Although the scope and definition of potential patient safety incidents in hospice is unique, the events observed in this study are similar to those observed with in other settings. This study identifies an operating definition and a potential classification for further research on patient safety incidents in hospice. Further research and consensus building of the definition of patient safety incidents and patient safety incidents in this setting is recommended.

Pure fluids and fluid mixtures near critical points are identified and are related to the progress of several disciplines. Consideration is given to thermodynamic properties, transport properties, and the complex nonlinear phenomena which occur when fluids undergo phase transitions in the critical region. The distinction is made between practical limits which may be extended by advances in technology and intrinsic ones which arise from the modification of fluid properties by the earth's gravitational field. The kinds of experiments near critical points which could best exploit the low gravity environment of an orbiting laboratory are identified. These include studies of the index of refraction, constant volume specific heat, and phase separation.

The fast iris image clarity evaluation based on Tenengrad and ROI selection

NASA Astrophysics Data System (ADS)

Gao, Shuqin; Han, Min; Cheng, Xu

2018-04-01

In iris recognition system, the clarity of iris image is an important factor that influences recognition effect. In the process of recognition, the blurred image may possibly be rejected by the automatic iris recognition system, which will lead to the failure of identification. Therefore it is necessary to evaluate the iris image definition before recognition. Considered the existing evaluation methods on iris image definition, we proposed a fast algorithm to evaluate the definition of iris image in this paper. In our algorithm, firstly ROI (Region of Interest) is extracted based on the reference point which is determined by using the feature of the light spots within the pupil, then Tenengrad operator is used to evaluate the iris image's definition. Experiment results show that, the iris image definition algorithm proposed in this paper could accurately distinguish the iris images of different clarity, and the algorithm has the merit of low computational complexity and more effectiveness.

Evaluation of a Hyperlinked Consumer Health Dictionary for reading EHR notes.

PubMed

Slaughter, Laura; Oyri, Karl; Fosse, Erik

2011-01-01

In this paper, we report on a pilot study conducted to test the usefulness and understandability of definitions in a Consumer Health Dictionary (IVS-CHD). Our two main goals for this study were to evaluate functionality of the dictionary when embedded in electronic health records (EHR) and determine the methodology for our larger-scale project to iteratively develop the IVS-CHD. The hyperlinked IVS-CHD was made available to thoracic surgery patients reading their own EHR. We asked patients to rate definitions on two 5-level Likert items measuring perceived usefulness and understandability. We also captured the terms that patients wanted defined, but that were not included in the IVS-CHD. Preliminary results indicate the types of problems that must be avoided when creating definitions, for example, that patients prefer detailed explanations that include medical outcomes, and that do not use "unfamiliar" terms they must also look up. We also have gained insight into the types of terms that patients want defined from their EHR notes, especially certain abbreviations. Patients further commented on the experience of reading EHR notes directly from the same system used by healthcare personnel and the help strategy of linking the contents to a hyperlinked dictionary.

Social Interest in The Polish Doctrine of Monument Preservation

NASA Astrophysics Data System (ADS)

Antoszczyszyn, Marek

2017-10-01

The paper discusses a controversy surrounding the latest amendment to the text of the Polish Parliament Act Conservation and the Care of Monuments (2015). It is a common dictum that any edifice cannot exist without good foundations. In this particular case of the mentioned above Act, definition of monument appears to be such a basis. A social interest is one of the constituent elements of the definition mentioned above. In the first part of the paper the notion of the social interest expression has been discussed, particularly from national and international points of view. The second part of the paper comprises some examples from the Polish monument preservation experience with the use of comparison method supported by case study. Only three big Polish cities: Warsaw, Wroclaw and Szczecin are involved in the presented case study but it must be emphasized that many other places on Polish territory experienced the same. Basing on the faith of these cities, the results and discussion chapter proves fundamental discrepancy in social interest notion between national and international scopes using some analytical methods. Finally, in the discussion chapter some proposals for the future amendment of monument definition in the Act of Conservation and the Care of Monuments have been provided.

Premission and postmission simulation studies of the foot-controlled maneuvering unit for Skylab experiment T-020. [astronaut maneuvering equipment - space environment simulation

Hewes, D. E.; Glover, K. E.

1975-01-01

A Skylab experiment was conducted to study the maneuvering capabilities of astronauts using a relatively simple self-locomotive device, referred to as the foot-controlled maneuvering unit, and to evaluate the effectiveness of ground-based facilities simulating the operation of this device in weightless conditions of space. Some of the special considerations given in the definition and development of the experiment as related to the two ground-based simulators are reviewed. These simulators were used to train the test subjects and to obtain baseline data which could be used for comparison with the in-flight tests that were performed inside the Skylab orbital workshop. The results of both premission and postmission tests are discussed, and subjective comparisons of the in-flight and ground-based test conditions are presented.

2014-06-01

The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation developed the first evidence-based definition for lifelong premature ejaculation (PE) in 2007 and concluded that there were insufficient published objective data at that time to develop a definition for acquired PE. The aim of this article is to review and critique the current literature and develop a contemporary, evidence-based definition for acquired PE and/or a unified definition for both lifelong and acquired PE. In April 2013, the ISSM convened a second Ad Hoc Committee for the Definition of Premature Ejaculation in Bangalore, India. The same evidence-based systematic approach to literature search, retrieval, and evaluation used by the original committee was adopted. The committee unanimously agreed that men with lifelong and acquired PE appear to share the dimensions of short ejaculatory latency, reduced or absent perceived ejaculatory control, and the presence of negative personal consequences. Men with acquired PE are older, have higher incidences of erectile dysfunction, comorbid disease, and cardiovascular risk factors, and have a longer intravaginal ejaculation latency time (IELT) as compared with men with lifelong PE. A self-estimated or stopwatch IELT of 3 minutes was identified as a valid IELT cut-off for diagnosing acquired PE. On this basis, the committee agreed on a unified definition of both acquired and lifelong PE as a male sexual dysfunction characterized by (i) ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE); (ii) the inability to delay ejaculation on all or nearly all vaginal penetrations; and (iii) negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. The ISSM unified definition of lifelong and acquired PE represents the first evidence-based definition for these conditions. This definition will enable researchers to design methodologically rigorous studies to improve our understanding of acquired PE. © 2014 International Society for Sexual Medicine.

Counterfactual Definiteness and Bell's Inequality

NASA Astrophysics Data System (ADS)

Hess, Karl; Raedt, Hans De; Michielsen, Kristel

Counterfactual definiteness must be used as at least one of the postulates or axioms that are necessary to derive Bell-type inequalities. It is considered by many to be a postulate that is not only commensurate with classical physics (as for example Einstein's special relativity), but also separates and distinguishes classical physics from quantum mechanics. It is the purpose of this paper to show that Bell's choice of mathematical functions and independent variables implicitly includes counterfactual definiteness and reduces the generality of the physics of Bell-type theories so significantly that no meaningful comparison of these theories with actual Einstein-Podolsky-Rosen experiments can be made.

The potential of telehealth for 'business as usual' in outpatient clinics.

PubMed

Day, Karen; Kerr, Patricia

2012-04-01

A six-month pilot study was conducted to ascertain the value of using high-definition videoconferencing equipment in an outpatients' setting. The videoconferencing equipment, which included digital biometric equipment, was installed in the outpatient clinics of a remote health service in New Zealand. Use of the equipment was evaluated using action research techniques. Clinicians were interviewed about their assessment of the equipment's usefulness. Patients and their carers completed questionnaires about their clinic experience. During the pilot trial, 109 patients were seen in 25 clinics of six different specialities. Questionnaire results showed that patients and their companions had a good user experience, similar to a face-to-face appointment. Clinicians found that the large screen, sense of proximity, video clarity and definition, and lack of sound/picture lag worked well for certain types of outpatients' clinics, e.g. methadone maintenance clinics. The need for process changes made it difficult to turn telehealth into business as usual in an environment built for face-to-face appointments. We conclude that videoconference equipment has potential to become integral to outpatients' clinics.

The purpose of our study was to clarify any difficulties or problems that exist in Japanese healthcare sites regarding the selection of death anxiety as a nursing diagnosis. This study was a qualitative, inductive research design. The semistructured interviews were conducted on the participants who were nurses and had 3 or more years of clinical experience in Japan. Results showed four categories: "The Japanese have a culture of avoiding death," "It is extremely difficult to match diagnostic indicators and related factors with specific patient cases," "Other diagnoses exist that are effective and enable proactive intervention," and "The definition of death anxiety and the meaning of its diagnostic indicators are unintelligible." It is thought that nursing diagnoses that reflect specific cultural backgrounds require definitions appropriate to each country and appropriate revisions to diagnostic indicators. © 2016 NANDA International, Inc.

Redefining delusion based on studies of subjective paranormal ideation.

PubMed

Houran, James; Lange, Rense

2004-04-01

The DSM-IV definition of delusion is argued to be unsatisfactory because it does not explain the mechanism for delusion formation and maintenance, it implies that such beliefs are necessarily dysfunctional (pathological), it underestimates the social component to some delusions, and it is inconsistent with research indicating that delusions can be modified through techniques such as contradiction, confrontation, and cognitive-behavioral therapy. However, a well-replicated mathematical model of magical/delusional thinking based on a study of paranormal beliefs and experiences is consistent with the hypothesis that attributional processes play a central role in delusion formation and maintenance. The model suggests attributional processes serve the adaptive function of reducing fear associated with ambiguous stimuli and delusional thinking is on a continuum with nonpathological forms. Based on this collective research an amendment to the definition of delusion is proposed and its clinical implications are addressed.

Intentionality: evolutionary development in healing: a grounded theory study for holistic nursing.

PubMed

Zahourek, Rothlyn P

2005-03-01

Although intentionality has been implicated as a causal variable in healing research, its definition has been inconsistent and vague. The objective of this grounded theory study is to develop a substantive theory of intentionality in a naturalistic encounter between nurse-healers and their healee-clients, and to consider the implications for practice and research. Six expert nurse-healers and six healee-clients were interviewed as individuals and in dyads before and after treatments. Interviews and observational data were analyzed using the constant comparative method and synthesized analysis. Participants described their experience of intentionality in healing as an evolutionary process characterized by distinctive shifts. The theory of intentionality: the matrix for healing (IMH) includes definitions of intentionality and a conceptual framework of three developmental phases of intentionality (generic, healing, and transforming intentionalities). The predominant attribute, development, is described. The theory contributes to knowledge about healing and intentionality and has implications for practice and future research.

2015-01-29

In this survey, we aimed to build consensus and gather opinions on 'Kokoro-no care' or mental health services and psychosocial support (MHSPSS) after a disaster, among mental health professionals who engaged in care after the Great East Japan Earthquake. We recruited mental health professionals who engaged in support activities after the Great East Japan Earthquake, which included local health professionals in the affected areas and members of mental health care teams dispatched from outside (n = 131). Adopting the Delphi process, we proposed a definition of 'Kokoro-no care', and asked the participants to rate the appropriateness on a 5-point Likert scale. We also solicited free comments based on the participants' experiences during the disaster. After Round 1, we presented the summary statistics and comments, and asked the participants to re-rate the definition that had been modified based on their comments. This process was repeated twice, until the consensus criterion of ≥ 80% of the participants scoring ≥ 4 on the statement was fulfilled. In Round 1, 68.7% of the respondents rated the proposed definition ≥ 4 for its appropriateness, and 88.4% did so in Round 2. The comments were grouped into categories (and subcategories) based on those related to the definition in general (Appropriate, Continuum of MHSPSS, Cautions in operation, Alternative categorisation of care components, Whether the care component should be categorised according to the professional involved, Ambiguous use of psychology, and Others), to mental health services (Appropriate, More specification within mental health services, More explicit remarks on mental health services, and Others), and to psychosocial support (Whether the care component should be categorised according to the professional involved, Raising concerns about the terms, and Others), and others. We achieved a consensus on the definition of 'Kokoro-no care', and systematically obtained suggestions on the concept, and practical advice on operation, based on the participants' experiences from the Great East Japan Earthquake. This collective knowledge will serve as reference to prepare and respond to future disasters.

The experience of receiving therapeutic touch.

PubMed

Samarel, N

1992-06-01

The purpose of this qualitative study was to describe the patient's experience of receiving therapeutic touch (TT) treatments. The design was informed by phenomenology in the sense that it was searching for a definition of the lived experience of the phenomenon of TT. Data were obtained through one open-ended interview and a second clarifying interview of each subject. All data were subjected to content analysis. For participants, the lived experience of TT was described as a linear process that began with the perceived need for and decision to seek treatment. It progressed through one or more treatments and continued to have an impact upon the participants' lives. These findings were examined within the context of Martha Rogers' conceptual system. This study has shown that, for 20 participants receiving treatment, TT was a fulfilling multidimensional experience that facilitated personal growth. Such as experience can only enrich the lives of those who receive treatment. Certainly, a nursing intervention that can achieve such a positive influence has potential for use in all areas of nursing care and needs to be explored further.

The practicality of including the systemic inflammatory response syndrome in the definition of polytrauma: experience of a level one trauma centre.

PubMed

Butcher, Nerida E; Balogh, Zsolt J

2013-01-01

The systemic inflammatory response syndrome (SIRS) has been advocated as a significant predictor of outcome in trauma. Recent trauma literature has proposed SIRS as a surrogate for physiological derangements characteristic of polytrauma with some authors recommending its inclusion into the definition of polytrauma. The practicality of daily SIRS collection outside of specifically designed prospective trials is unknown. The purpose of this study was to assess the availability of SIRS variables and its appropriateness for inclusion into a definition of polytrauma. We hypothesised SIRS variables would be readily available and easy to collect, thus represent an appropriate inclusion into the definition of polytrauma. A prospective observational study of all trauma team activation patients over 7-months (August 2009 to February 2010) at a University affiliated level-1 urban trauma centre. SIRS data (temperature>38°C or <36°C; Pulse >90 bpm; RR>20/min or a PaCO(2)<32 mmHg; WCC>12.0×10(9)L(-1), or <4.0×10(9)L(-1), or the presence of >10 immature bands) collected from presentation, at 24 h intervals until 72 h post injury. Inclusion criteria were all patients generating a trauma team activation response age >16. 336 patients met inclusion criteria. In 46% (155/336) serial SIRS scores could not be calculated due to missing data. Lowest rates of missing data observed on admission [3% (11/336)]. Stratified by ISS>15 (132/336), in 7% (9/132) serial SIRS scores could not be calculated due to missing data. In 123 patients ISS>15 with complete data, 81% (100/123) developed SIRS. For Abbreviated Injury Scale (AIS)>2 in at least 2 body regions (64/336) in 5% (3/64) serial SIRS scores could not be calculated, with 92% (56/61) of patients with complete data developing SIRS. For Direct ICU admissions [25% (85/336)] 5% (4/85) of patients could not have serial SIRS calculated [mean ISS 15(±11)] and 90% (73/81) developed SIRS at least once over 72 h. Based on the experience of our level-1 trauma centre, the practicability of including SIRS into the definition of polytrauma as a surrogate for physiological derangement appears questionable even in prospective fashion.

How states, tribes and localities are re-defining systems of care.

PubMed

Pires, Sheila A

2010-02-01

The original definition of system of care was developed 20 years ago largely in response to the fragmented services experienced by children with serious emotional disorders and their families, who, typically, were involved in multiple systems and/or receiving services from different providers. Over time, in response to national funders' pursuing system of care for different populations and their own experience, states, tribes and localities have applied system of care principles, values and operational characteristics to other populations (children and adults). The definition offered by Hodges et al., has an unintended effect of constraining the properties (and potential) of system of care in its limitation to a single population. This paper argues that the adaptations made to the original Stroul and Friedman definition in the training curriculum Building Systems of Care: A Primer adequately encompass properties that reflect state, tribal and local implementation experience and are specific to planning, implementing and evaluating a system of care, without limiting system of care to any one population.

Who Is Experiencing What Kind of Moral Distress? Distinctions for Moving from a Narrow to a Broad Definition of Moral Distress.

Moral distress, according to Andrew Jameton's highly influential definition, occurs when a nurse knows the morally correct action to take but is constrained in some way from taking this action. The definition of moral distress has been broadened, first, to include morally challenging situations that give rise to distress but which are not necessarily linked to nurses feeling constrained, such as those associated with moral uncertainty. Second, moral distress has been broadened so that it is not confined to the experiences of nurses. However, such a broadening of the concept does not mean that the kind of moral distress being experienced, or the role of the person experiencing it, is morally irrelevant. I argue that differentiating between categories of distress-e.g., constraint and uncertainty-and between groups of health professionals who might experience moral distress is potentially morally relevant and should influence the analysis, measurement, and amelioration of moral distress in the clinic. © 2017 American Medical Association.

1974-01-01

The methods and techniques for experiment development and integration that evolved during the Skylab Program are described to facilitate transferring this experience to experimenters in future manned space programs. Management responsibilities and the sequential process of experiment evolution from initial concept through definition, development, integration, operation and postflight analysis are outlined and amplified, as appropriate. Emphasis is placed on specific lessons learned on Skylab that are worthy of consideration by future programs.

Development of Gravity Sensitive Plant Cells (Ceratodon) in Microgravity

NASA Technical Reports Server (NTRS)

Sack, Fred D.

1999-01-01

Protonemata of the moss Ceratodon are tip-growing cells that grow up in the dark. This cell type is unique compared to cells in almost any other organism, since the growth of the plant cell itself is completely oriented by gravity. Thus, both the processes of gravity sensing and the gravity response occur in the same cell. Gravity sensing appears to rely upon amyloplasts (starch-filled plastids) that sediment. This sedimentation occurs in specific zones and plastid zonation is complex with respect to plastid morphology, distribution, and gravity. Microtubules restrict the extent of plastid sedimentation (i.e., they are load-bearing). Light also is important since apical cells have a phytochrome-based positive phototropism, light quality influences plastid zonation and sedimentation (photomorphogenesis), and red light suppresses gravitropism at higher but not lower light intensities. Many of these processes were examined in a 16 day spaceflight experiment, "SPM-A" space moss" or "SPAM)) on STS-87 that landed in December, 1997. The work described here involves the definition of a second flight experiment that builds upon the data and questions arising from STS-87. Effort was directed towards further definition of an experiment for the Shuttle (dubbed "SOS" for "Son of SPAM"). Our current target is STS 107 that is scheduled to fly in January 2001. This definition addressed two goals of the STS107 experiment. The goals of the current experiment were to determine whether the cytoskeleton plays a role in maintaining and generating an apical (non-random) plastid distribution in microgravity and to determine the development and extent of clockwise spiral tip-growth in microgravity.

“Patient-Time,” “Doctor-Time,” and “Institution-Time”: Perceptions and Definitions of Time Among Doctors Who Become Patients

PubMed Central

Klitzman, Robert

2010-01-01

Objective To examine views and experiences of conflicts concerning time in healthcare, from the perspective of physicians who have become patients. Methods We conducted two in-depth semi-structured two-hour interviews concerning experiences of being health care workers, and becoming a patient, with each of 50 doctors who had serious illnesses. Results These doctor-patients often came to realize as they had not before how patients experience time differently, and how “patient-time,” “doctor-time,” and “institution-time” exist and can conflict. Differences arose in both long and short term, regarding historical time (prior eras/decades in medicine), prognosis (months/years), scheduling delays (days/weeks), daily medical events and tasks (hours), and periods in waiting rooms (minutes/hours). Definitions of periods of time (e.g., “fast,” “slow,” “plenty,” and “soon”) also varied widely, and could clash. Professional socialization had heretofore impeded awareness of these differences. Physicians tried to address these conflicts in several ways (e.g., trying to provide test results promptly), though full resolution remained difficult. Conclusions Doctors who became patients often now realized how physicians and patients differ in subjective experiences of time. Medical education and research have not adequately considered these issues, which can affect patient satisfaction, doctor-patient relationships and communication, and care. Practice Implications Physicians need to be more sensitive to how their definitions, perceptions, and experiences concerning time can differ from those of patients. PMID:17125956

1977-01-01

A flight experiment and flight experiment package for a shuttle-borne flight test of an 8-cm mercury ion thruster was designed to obtain charged particle and neutral particle material transport data that cannot be obtained in conventional ground based laboratory testing facilities. By the use of both ground and space testing of ion thrusters, the flight worthiness of these ion thrusters, for other spacecraft applications, may be demonstrated. The flight experiment definition for the ion thruster initially defined a broadly ranging series of flight experiments and flight test sensors. From this larger test series and sensor list, an initial flight test configuration was selected with measurements in charged particle material transport, condensible neutral material transport, thruster internal erosion, ion beam neutralization, and ion thrust beam/space plasma electrical equilibration. These measurement areas may all be examined for a seven day shuttle sortie mission and for available test time in the 50 - 100 hour period.

Inflated concepts for the earth science geostationary platform and an associated flight experiment

NASA Technical Reports Server (NTRS)

Friese, G.

1992-01-01

Large parabolic reflectors and solar concentrators are of great interest for microwave transmission, solar powered rockets, and Earth observations. Collector subsystems have been under slow development for a decade. Inflated paraboloids have a great weight and package volume advantage over mechanically erected systems and, therefore, have been receiving greater attention recently. The objective of this program was to produce a 'conceptual definition of an experiment to assess in-space structural damping characteristics and effects of the space meteoroid environment upon structural integrity and service life of large inflatable structures.' The flight experiment was to have been based upon an inflated solar concentration, but much of that was being done on other programs. To avoid redundancy, the Earth Science Geostationary Platform (ESGP) was selected as a focus mission for the experiment. Three major areas were studied: the ESGP reflector configuration; flight experiment; and meteoroids.

In-Space technology experiments program. A high efficiency thermal interface (using condensation heat transfer) between a 2-phase fluid loop and heatpipe radiator: Experiment definition phase

NASA Technical Reports Server (NTRS)

Pohner, John A.; Dempsey, Brian P.; Herold, Leroy M.

1990-01-01

Space Station elements and advanced military spacecraft will require rejection of tens of kilowatts of waste heat. Large space radiators and two-phase heat transport loops will be required. To minimize radiator size and weight, it is critical to minimize the temperature drop between the heat source and sink. Under an Air Force contract, a unique, high-performance heat exchanger is developed for coupling the radiator to the transport loop. Since fluid flow through the heat exchanger is driven by capillary forces which are easily dominated by gravity forces in ground testing, it is necessary to perform microgravity thermal testing to verify the design. This contract consists of an experiment definition phase leading to a preliminary design and cost estimate for a shuttle-based flight experiment of this heat exchanger design. This program will utilize modified hardware from a ground test program for the heat exchanger.

Solar array flight dynamic experiment

1986-01-01

The purpose of the Solar Array Flight Dynamic Experiment (SAFDE) is to demonstrate the feasibility of on-orbit measurement and ground processing of large space structures dynamic characteristics. Test definition or verification provides the dynamic characteristic accuracy required for control systems use. An illumination/measurement system was developed to fly on space shuttle flight STS-31D. The system was designed to dynamically evaluate a large solar array called the Solar Array Flight Experiment (SAFE) that had been scheduled for this flight. The SAFDE system consisted of a set of laser diode illuminators, retroreflective targets, an intelligent star tracker receiver and the associated equipment to power, condition, and record the results. In six tests on STS-41D, data was successfully acquired from 18 retroreflector targets and ground processed, post flight, to define the solar array's dynamic characteristic. The flight experiment proved the viability of on-orbit test definition of large space structures dynamic characteristics. Future large space structures controllability should be greatly enhanced by this capability.

The impact of negative childbirth experience on future reproductive decisions: A quantitative systematic review.

PubMed

Shorey, Shefaly; Yang, Yen Yen; Ang, Emily

2018-06-01

The aim of this study was to systematically retrieve, critique and synthesize available evidence regarding the association between negative childbirth experiences and future reproductive decisions. A child's birth is often a joyous event; however, there is a proportion of women who undergo negative childbirth experiences that have long-term implications on their reproductive decisions. A systematic review of quantitative studies was undertaken using Joanna Briggs Institute's methods. A search was carried out in CINAHL Plus with Full Text, Embase, PsycINFO, PubMed, Scopus and Web of Science from January 1996 - July 2016. Studies that fulfilled the inclusion criteria were assessed by two independent reviewers using the Joanna Briggs Institute's Critical Appraisal Tools. Data were extracted under subheadings adapted from the institute's data extraction forms. Twelve studies, which examined either one or more influences of negative childbirth experiences, were identified. The included studies were either cohort or cross-sectional designs. Five studies observed positive associations between prior negative childbirth experiences and decisions to not have another child, three studies found positive associations between negative childbirth experiences and decisions to delay a subsequent birth and six studies concluded positive associations between negative childbirth experiences and maternal requests for caesarean section in subsequent pregnancies. To receive a holistic understanding on negative childbirth experiences, a suitable definition and validated measuring tools should be used to understand this phenomenon. Future studies or reviews should include a qualitative component and/or the exploration of specific factors such as cultural and regional differences that influence childbirth experiences. © 2018 John Wiley & Sons Ltd.

Technologies of democracy: experiments and demonstrations.

PubMed

Laurent, Brice

2011-12-01

Technologies of democracy are instruments based on material apparatus, social practices and expert knowledge that organize the participation of various publics in the definition and treatment of public problems. Using three examples related to the engagement of publics in nanotechnology in France (a citizen conference, a series of public meetings, and an industrial design process), the paper argues that Science and Technology Studies provide useful tools and methods for the analysis of technologies of democracy. Operations of experiments and public demonstrations can be described, as well as controversies about technologies of democracy giving rise to counter-experiments and counter-demonstrations. The political value of the analysis of public engagement lies in the description of processes of stabilization of democratic orders and in the display of potential alternative political arrangements.

Students' integration of multiple representations in a titration experiment

NASA Astrophysics Data System (ADS)

Kunze, Nicole M.

A complete understanding of a chemical concept is dependent upon a student's ability to understand the microscopic or particulate nature of the phenomenon and integrate the microscopic, symbolic, and macroscopic representations of the phenomenon. Acid-base chemistry is a general chemistry topic requiring students to understand the topics of chemical reactions, solutions, and equilibrium presented earlier in the course. In this study, twenty-five student volunteers from a second semester general chemistry course completed two interviews. The first interview was completed prior to any classroom instruction on acids and bases. The second interview took place after classroom instruction, a prelab activity consisting of a titration calculation worksheet, a titration computer simulation, or a microscopic level animation of a titration, and two microcomputer-based laboratory (MBL) titration experiments. During the interviews, participants were asked to define and describe acid-base concepts and in the second interview they also drew the microscopic representations of four stages in an acid-base titration. An analysis of the data showed that participants had integrated the three representations of an acid-base titration to varying degrees. While some participants showed complete understanding of acids, bases, titrations, and solution chemistry, other participants showed several alternative conceptions concerning strong acid and base dissociation, the formation of titration products, and the dissociation of soluble salts. Before instruction, participants' definitions of acid, base, and pH were brief and consisted of descriptive terms. After instruction, the definitions were more scientific and reflected the definitions presented during classroom instruction.

More Than a Destination: Contraceptive Decision Making as a Journey.

PubMed

Downey, Margaret Mary; Arteaga, Stephanie; Villaseñor, Elodia; Gomez, Anu Manchikanti

Contraceptive use is widely recognized as a means of reducing adverse health-related outcomes. However, dominant paradigms of contraceptive counseling may rely on a narrow definition of "evidence" (i.e., scientifically accurate but exclusive of individual women's experiences). Given increased enthusiasm for long-acting, reversible contraceptive methods, such paradigms may reinforce counseling that overprivileges effectiveness, particularly for groups considered at high risk of unintended pregnancy. This study investigates where and how women's experiences fit into the definition of evidence these counseling protocols use. Using a qualitative approach, this analysis draws on semistructured interviews with 38 young (ages 18-24) Black and Latina women. We use a qualitative content analysis approach, with coding categories derived directly from the textual data. Our analysis suggests that contraceptive decision making is an iterative, relational, reflective journey. Throughout contraceptive histories, participants described experiences evolving to create a foundation from which decision-making power was drawn. The same contraceptive-related decisions were revisited repeatedly, with knowledge accrued along the way. The cumulative experience of using, assigning meanings to, and developing values around contraception meant that young women experienced contraceptive decision making as a dynamic process. This journey creates a rich body of evidence that informs contraceptive decision making. To provide appropriate, acceptable, patient-centered family planning care, providers must engage with evidence grounded in women's expertise on their contraceptive use in addition to medically accurate data on method effectiveness, side effects, and contraindications.

In recent years, the interest in user experience (UX) evaluation methods for assessing technology solutions, especially in health systems for children with special needs like cognitive disabilities, has increased. Conduct a systematic mapping study to provide an overview in the field of UX evaluations in rehabilitation video games for children. The definition of research questions, the search for primary studies and the extraction of those studies by inclusion and exclusion criteria lead to the mapping of primary papers according to a classification scheme. Main findings from this study include the detection of the target population of the selected studies, the recognition of two different ways of evaluating UX: (i) user evaluation and (ii) system evaluation, and UX measurements and devices used. This systematic mapping specifies the research gaps identified for future research works in the area.

[How do adolescents in Germany define cyberbullying? A focus-group study of adolescents from a German major city].

PubMed

Höher, Jonas; Scheithauer, Herbert; Schultze-Krumbholz, Anja

2014-01-01

A steadily growing number of empirical research on cyberbullying exists retaining the traditional definition of bullying. However, whether this scientific and theoretical definition represents youths' perceptions and experiences with cyberbullying is a subject of further investigation. Scenarios of cyberbullying incidents were used and later discussed in three focus groups with 20 adolescents (55 % boys, 45 % girls, 11-16 years old). Thematic and content analyses laid focus on the following questions: (1) Which terms are used by the adolescents to describe the behaviors in the incidents? (2) What are the roles of traditional bullying definition criteria (i. e. intention, repetition, and power imbalance) and two additional cyberbullying-specific criteria (i. e. anonymity and publicity)? (3) How are the behaviors perceived in comparison to each other? Results show that German adolescents perceive "cybermobbing" as the best term to describe the presented incidents. Impersonation was not perceived as cyberbullying by the adolescents, but rather viewed as a criminal act. In addition, adolescents perceived the intent to harm, the impact on the victim, and repetition relevant for defining cyberbullying. Moreover, analyses revealed an interdependence between criteria which suggests that anonymity and publicity have an effect on the severity of the behavior, however they were not essential for the definition of cyberbullying.

To examine if there was spatial misclassification in exposure to neighborhood noise complaints among a sample of low-income housing residents in New York City, comparing home-based spatial buffers and Global Positioning System (GPS) daily path buffers. Data came from the community-based NYC Low-Income Housing, Neighborhoods and Health Study, where GPS tracking of the sample was conducted for a week (analytic n = 102). We created a GPS daily path buffer (a buffering zone drawn around GPS tracks) of 200 m and 400 m. We also used home-based buffers of 200 m and 400 m. Using these "neighborhoods" (or exposure areas), we calculated neighborhood exposure to noisy events from 311 complaints data (analytic n = 143,967). Friedman tests (to compare overall differences in neighborhood definitions) were applied. There were differences in neighborhood noise complaints according to the selected neighborhood definitions (P < .05). For example, the mean neighborhood noise complaint count was 1196 per square kilometer for the 400-m home-based and 812 per square kilometer for the 400-m activity space buffer, illustrating how neighborhood definition influences the estimates of exposure to neighborhood noise complaints. These analyses suggest that, whenever appropriate, GPS neighborhood definitions can be used in spatial epidemiology research in spatially mobile populations to understand people's lived experience.

Repetition priming with Japanese Kana scripts in word-fragment completion.

PubMed

Komatsu, S; Naito, M

1992-03-01

Manipulating two types of Japanese Kana script, Katakana and Hiragana, we examined the effects of a script change between study and test on later word-fragment completion. Throughout three experiments, materials were composed of foreign loan nouns normally written in Katakana, but not in Hiragana, according to approved usage in Japanese. Experiment 1 demonstrated the reliable size of cross-script priming between Katakana and Hiragana. In Experiment 2, cross-modal priming was substantial when modality of presentation was changed from auditory to visual. In Experiment 3, generating a target word from its definition induced priming comparable in size to that in the prior reading condition. These results have been confirmed in the Hiragana test, as well as in the Katakana test, thereby suggesting that some conceptual and modality-independent processes may also mediate repetition priming.

Many health care systems now allow patients to access their electronic health record (EHR) notes online through patient portals. Medical jargon in EHR notes can confuse patients, which may interfere with potential benefits of patient access to EHR notes. The aim of this study was to develop and evaluate the usability and content quality of NoteAid, a Web-based natural language processing system that links medical terms in EHR notes to lay definitions, that is, definitions easily understood by lay people. NoteAid incorporates two core components: CoDeMed, a lexical resource of lay definitions for medical terms, and MedLink, a computational unit that links medical terms to lay definitions. We developed innovative computational methods, including an adapted distant supervision algorithm to prioritize medical terms important for EHR comprehension to facilitate the effort of building CoDeMed. Ten physician domain experts evaluated the user interface and content quality of NoteAid. The evaluation protocol included a cognitive walkthrough session and a postsession questionnaire. Physician feedback sessions were audio-recorded. We used standard content analysis methods to analyze qualitative data from these sessions. Physician feedback was mixed. Positive feedback on NoteAid included (1) Easy to use, (2) Good visual display, (3) Satisfactory system speed, and (4) Adequate lay definitions. Opportunities for improvement arising from evaluation sessions and feedback included (1) improving the display of definitions for partially matched terms, (2) including more medical terms in CoDeMed, (3) improving the handling of terms whose definitions vary depending on different contexts, and (4) standardizing the scope of definitions for medicines. On the basis of these results, we have improved NoteAid's user interface and a number of definitions, and added 4502 more definitions in CoDeMed. Physician evaluation yielded useful feedback for content validation and refinement of this innovative tool that has the potential to improve patient EHR comprehension and experience using patient portals. Future ongoing work will develop algorithms to handle ambiguous medical terms and test and evaluate NoteAid with patients. ©Jinying Chen, Emily Druhl, Balaji Polepalli Ramesh, Thomas K Houston, Cynthia A Brandt, Donna M Zulman, Varsha G Vimalananda, Samir Malkani, Hong Yu.

Perinatal Bereavement: A Principle-based Concept Analysis

PubMed Central

FENSTERMACHER, Kimberly; HUPCEY, Judith E.

2013-01-01

Aim This paper is a report of an analysis of the concept of perinatal bereavement. Background The concept of perinatal bereavement emerged in the scientific literature during the 1970s. Perinatal bereavement is a practice based concept, although it is not well defined in the scientific literature and is often intermingled with the concepts of mourning and grief. Design Concept Analysis. Data Sources Using the term ‘perinatal bereavement’ and limits of only English and human, Pub Med and CINAHL were searched to yield 278 available references dating from 1974 – 2011. Articles specific to the experience of perinatal bereavement were reviewed. The final data set was 143 articles. Review Methods The methods of principle-based concept analysis were used. Results reveal conceptual components (antecedents, attributes and outcomes) which are delineated to create a theoretical definition of perinatal bereavement. Results The concept is epistemologically immature, with few explicit definitions to describe the phenomenon. Inconsistency in conceptual meaning threatens the construct validity of measurement tools for perinatal bereavement and contributes to incongruent theoretical definitions. This has implications for both nursing science (how the concept is studied and theoretically integrated) and clinical practice (timing and delivery of support interventions). Conclusions Perinatal bereavement is a multifaceted global phenomenon that follows perinatal loss. Lack of conceptual clarity and lack of a clearly articulated conceptual definition impede the synthesis and translation of research findings into practice. A theoretical definition of perinatal bereavement is offered as a platform for researchers to advance the concept through research and theory development. PMID:23458030

Background Motor learning is central to domains such as sports and rehabilitation; however, often terminologies are insufficiently uniform to allow effective sharing of experience or translation of knowledge. A study using a Delphi technique was conducted to ascertain level of agreement between experts from different motor learning domains (i.e., therapists, coaches, researchers) with respect to definitions and descriptions of a fundamental conceptual distinction within motor learning, namely implicit and explicit motor learning. Methods A Delphi technique was embedded in multiple rounds of a survey designed to collect and aggregate informed opinions of 49 international respondents with expertise related to motor learning. The survey was administered via an online survey program and accompanied by feedback after each round. Consensus was considered to be reached if ≥70% of the experts agreed on a topic. Results Consensus was reached with respect to definitions of implicit and explicit motor learning, and seven common primary intervention strategies were identified in the context of implicit and explicit motor learning. Consensus was not reached with respect to whether the strategies promote implicit or explicit forms of learning. Discussion The definitions and descriptions agreed upon may aid translation and transfer of knowledge between domains in the field of motor learning. Empirical and clinical research is required to confirm the accuracy of the definitions and to explore the feasibility of the strategies that were identified in research, everyday practice and education.

The study, funded by the Northwest Health Foundation of Portland, Oregon and the National Institute on Drug Abuse (NIDA), was conducted as part of the HEARTH collaborative (Housing, Employment and Recovery Together for Health). HEARTH, established in 2010, is a community-academic partnership involving partners from Portland State University (PSU), Oregon Health and Science University (OHSU), and Central City Concern (CCC). Using the approaches of community-based participatory research (CBPR), these diverse stakeholders collaborated to co-develop research of direct relevance to the local community and to national academic and policy communities. This study employed qualitative methods and community-based participatory research principles to solicit personal experiences with housing, employment, and recovery programs. We recruited interview participants via CCC-operated housing programs, including Alcohol and Drug Free Community Housing (ADFC), family housing, transitional housing, and non-ADFC (low barrier) housing units. The manuscript presents interview themes based on the five broad categories of interview questions: housing, employment programs, recovery programs, definitions of recovery, and definitions of success. Co-authors describe recommendations for practice and research protocol based on our findings. Our results highlight the importance of involving consumers in the development, data collection, and analysis of research, and present the unique perspectives of those who experience homelessness, recovery, and the programs designed to assist them.

HEARTH, established in 2010, is a community-academic partnership involving partners from Portland State University (PSU), Oregon Health and Science University (OHSU), and Central City Concern (CCC). Using the approaches of community-based participatory research (CBPR), these diverse stakeholders collaborated to co-develop research of direct relevance to the local community and to national academic and policy communities. This study employed qualitative methods and community-based participatory research principles to solicit personal experiences with housing, employment, and recovery programs. We recruited interview participants via CCC-operated housing programs, including Alcohol and Drug Free Community Housing (ADFC), family housing, transitional housing, and non-ADFC (low barrier) housing units. The manuscript presents interview themes based on the five broad categories of interview questions: housing, employment programs, recovery programs, definitions of recovery, and definitions of success. Co-authors describe recommendations for practice and research protocol based on our findings. Our results highlight the importance of involving consumers in the development, data collection, and analysis of research, and present the unique perspectives of those who experience homelessness, recovery, and the programs designed to assist them.

Unlike the original definitions of focal (FA) and diffuse anaplasia (DA) in Wilms tumor (WT), recently redefined FA and DA proved to be of prognostic significance. The aim of the study was to analyze WT from the SIOP file, the majority of which were treated with preoperative chemotherapy, in order to investigate whether chemotherapy influenced the presence of anaplasia, whether the new definitions were applicable to these tumors, and whether they were of prognostic significance. The unilateral anaplastic WT of children up to 16 years of age from the SIOP 6 and 9 nephroblastoma trials and studies were first classified according to the original definitions and analyzed. Then they were reclassified and analyzed according to the new definitions. Anaplasia was diagnosed in 86 (5.5%) of 1,554 unilateral WT. The age at diagnosis ranged from 9 to 175 months (median, 63) and more than half of children were over 5 years of age. From 15% to 85% of the tumor mass showed chemotherapy-induced changes. Blastemal anaplasia was seen in 74, stromal in 23, and epithelial in 22 cases. According to the original definitions, FA was diagnosed in 55 (64%) and DA in 31 (36%) cases. In total, 48% children were alive and well, including 53% with FA and 39% with DA (P = 0.23). When reclassified, 39 old FA cases were moved to the new DA group, resulting in 70 (81%) DA and 16 (19%) FA cases. The female-to-male ratio for FA changed from 1.9:1 to 1:1 while remained unchanged for DA. The percentage of FA stage I cases increased from 31% to 44%, while it decreased from 25% to 6% for stage III. For other stages it remained virtually unchanged. The overall 4-year actual survival was 75% for FA and 41% for DA (P = 0.03). Preoperative chemotherapy did not obliterate or produce anaplasia. The new definitions were applicable to pretreated cases and they were of prognostic significance.

The Space Station structure has been baselined to be a 5 M (16.4 ft) erectable truss. This structure will provide the overall framework to attach laboratory modules and other systems, subsystems and utilities. The assembly of this structure represents a formidable EVA challenge. To validate this capability the Space Station Structures/Dynamics Technical Integration Panel (TIP) met to develop the necessary data for an integrated STS structures flight experiment. As a result of this meeting, the Langley Research Center initiated a joint Langley/Boeing Aerospace Company study which supported the structures/dynamics TIP in developing the preliminary definition and design of a 5 M erectable space station truss and the resources required for a proposed flight experiment. The purpose of the study was to: (1) devise methods of truss assembly by astronauts; (2) define a specific test matrix for dynamic characterization; (3) identify instrumentation and data system requirements; (4) determine the power, propulsion and control requirements for the truss on-orbit for 3 years; (5) study the packaging of the experiment in the orbiter cargo bay; (6) prepare a preliminary cost estimate and schedule for the experiment; and (7) provide a list of potential follow-on experiments using the structure as a free flyer. The results of this three month study are presented.

Toward a theory of online communication in illness: concept analysis of illness blogs.

PubMed

Heilferty, Catherine McGeehin

2009-07-01

This paper is a report of a concept analysis of illness blogs and their relevance to nursing research on communication during illness. Blogs are being used by patients and family members to describe the experience of illness, but very little is known about this phenomenon. Seventeen English language databases and one Internet search engine were searched from 1990 to 2007 using the truncated term 'blog*'. Specific illness terms together with 'blog*', for example, blog* and diabetes; and blog* and cancer, were used to expand the search. Reports were included if they were of qualitative or quantitative research that included a definition of blogs or blogging and some identification or description of blog uses pertinent to the discipline. Specific emphasis was placed on blog use by individuals coping with illness experiences. 'Meta' writings by authors about their own blogging intentions and experiences were excluded. An illness blog is the online expression of the narrative of illness. Theoretical and operational definitions, defining attributes, uses, antecedents and consequences were developed. The literature search returned 45 works from 17 disciplines referring to the definition and uses of blogging. Support is offered from the review of literature and analysis of the concept for the development of a theory of online communication during illness. Reading and incorporating illness blogs into care will enhance patient-provider relationships. Analysis of the narratives being created online about the illness experience will contribute significantly to nursing's body of knowledge.

The mind as a process.

Bruhn, John G; Wolf, Stewart

Essentially all behavior is regulated by the brain in response to information received from within the body or from the environment. The tangible structures of the brain serve as devices for processing thoughts and emotions as well as information. Stored among the interacting neural structures are memories of past experiences and responses to them. These intangibles participate in determining the decisions made and the actions performed by the brain's structures. There are valuable studies of the clinical and neurological effects of environmental stimuli, but we need to learn more about the processes that lead to these effects. More definitive correlations could be made between environmental stimuli and the neurological pathways they create by studying individual's real life experiences rather than laboratory simulations alone.

On the definition of absorbed dose

NASA Astrophysics Data System (ADS)

Grusell, Erik

2015-02-01

Purpose: The quantity absorbed dose is used extensively in all areas concerning the interaction of ionizing radiation with biological organisms, as well as with matter in general. The most recent and authoritative definition of absorbed dose is given by the International Commission on Radiation Units and Measurements (ICRU) in ICRU Report 85. However, that definition is incomplete. The purpose of the present work is to give a rigorous definition of absorbed dose. Methods: Absorbed dose is defined in terms of the random variable specific energy imparted. A random variable is a mathematical function, and it cannot be defined without specifying its domain of definition which is a probability space. This is not done in report 85 by the ICRU, mentioned above. Results: In the present work a definition of a suitable probability space is given, so that a rigorous definition of absorbed dose is possible. This necessarily includes the specification of the experiment which the probability space describes. In this case this is an irradiation, which is specified by the initial particles released and by the material objects which can interact with the radiation. Some consequences are discussed. Specific energy imparted is defined for a volume, and the definition of absorbed dose as a point function involves the specific energy imparted for a small mass contained in a volume surrounding the point. A possible more precise definition of this volume is suggested and discussed. Conclusions: The importance of absorbed dose motivates a proper definition, and one is given in the present work. No rigorous definition has been presented before.

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 science teachers' perceptions of experimentation: implications for restructuring school practical work

NASA Astrophysics Data System (ADS)

Wei, Bing; Li, Xiaoxiao

2017-09-01

It is commonly recognised that practical work has a distinctive and central role in science teaching and learning. Although a large number of studies have addressed the definitions, typologies, and purposes of practical work, few have consulted practicing science teachers. This study explored science teachers' perceptions of experimentation for the purpose of restructuring school practical work in view of science practice. Qualitative interviews were conducted with 87 science teachers at the secondary school level. In the interviews, science teachers were asked to make a comparison between students' experiments and scientific experiments. Eight dimensions of experimentation were generated from the qualitative data analysis, and the distributions of these eight dimensions between the two types of experiments were compared and analysed. An ideal model of practical work was suggested for restructuring practical work at the secondary school level, and some issues related to the effective enactment of practical work were discussed.

1971-01-01

Preliminary designs of the Bioexplorer spacecraft, developed in an earlier study program, are analyzed and updated to conform to a new specification which includes use of both the Scout and the space shuttle vehicle for launch. The updated spacecraft is referred to as bioresearch module. It is capable of supporting a variety of small biological experiments in near-earth and highly elliptical earth orbits. The baseline spacecraft design is compatible with the Scout launch vehicle. Inboard profile drawings, weight statements, interface drawings, and spacecraft parts and aerospace ground equipment lists are provided to document the design. The baseline design was analyzed to determine the design and cost impact of a set of optional features. These include reduced experiment power and thermal load, addition of an experiment television monitor, and replacement of VHF with S-band communications. The impact of these options on power required, weight change and cost is defined.

An inventory on the two critical dimensions that structure the Randomized Controlled Trial in Psychiatry, namely the definition of inclusion criteria for eligible patients for testing and the choice of psychometric methods of pathology assessment and its evolution during the experiment, considers the importance of increasingly numerous and precise international recommendations. Taking into account the formal constraints of industrial, questioning the cultural differences of the methodological approach of the tests, meeting the requirements of feasibility and ever increasing security, frequent cumbersome procedure often contrasts with the modest nature of the results. A better definition to include patients in randomized trials is desirable and it asks to return to the clinic studying the expectations of patients and their response to the therapeutic situation. Excessive standardization otherwise required for ensuring the objective nature of the assessment hampers the collection of original and varied clinical features of importance in the further definitions of indications. On the way to a resumption of the single case study, we can expect from qualitative methods applied to small groups of subjects, optimization principles of patient selection for the upcoming randomized trial and greater chance to address the relevant details of clinical response to the therapeutic situation. This is what has led to the discovery of psychotropic drugs and which is involved in the various modalities of the qualitative approach. For example, and beyond the exploration of clinical drug effects, the study of the experience of psychiatric inpatient care in the Healing Garden, conducted on a small group and on the basis of the narrative analysis of their experience, notes several operating thematic dimensions: a reduction in the perception of symptoms of the disease, the impression of regaining a foothold into reality, the interest of a differently perceived doctor-patient relationship, the advantage of renewed power to act and the recognition of the importance of support from others, patients recovering somehow « vitality » of touch with reality. This suggests the possibility to establish an appropriate rating scale for such a specific therapeutic situation and to provide a more accurate and efficient recruitment for a comparative objective demonstration. Moreover, this construction of meaning reinforces the therapeutic benefit of treatment in Healing Garden and offers new dimensions for research. © L’Encéphale, Paris, 2016.

The care unit in nursing home research: Evidence in support of a definition

PubMed Central

2011-01-01

Background Defining what constitutes a resident care unit in nursing home research is both a conceptual and practical challenge. The aim of this paper is to provide evidence in support of a definition of care unit in nursing homes by demonstrating: (1) its feasibility for use in data collection, (2) the acceptability of aggregating individual responses to the unit level, and (3) the benefit of including unit level data in explanatory models. Methods An observational study design was used. Research (project) managers, healthcare aides, care managers, nursing home administrators and directors of care from thirty-six nursing homes in the Canadian prairie provinces of Alberta, Saskatchewan and Manitoba provided data for the study. A definition of care unit was developed and applied in data collection and analyses. A debriefing session was held with research managers to investigate their experiences with using the care unit definition. In addition, survey responses from 1258 healthcare aides in 25 of the 36 nursing homes in the study, that had more than one care unit, were analyzed using a multi-level modeling approach. Trained field workers administered the Alberta Context Tool (ACT), a 58-item self-report survey reflecting 10 organizational context concepts, to healthcare aides using computer assisted personal interviews. To assess the appropriateness of obtaining unit level scores, we assessed aggregation statistics (ICC(1), ICC(2), η2, and ω2), and to assess the value of using the definition of unit in explanatory models, we performed multi-level modeling. Results In 10 of the 36 nursing homes, the care unit definition developed was used to align the survey data (for analytic purposes) to specific care units as designated by our definition, from that reported by the facility administrator. The aggregation statistics supported aggregating the healthcare aide responses on the ACT to the realigned unit level. Findings from the multi-level modeling further supported unit level aggregation. A significantly higher percentage of variance was explained in the ACT concepts at the unit level compared to the individual and/or nursing home levels. Conclusions The statistical results support the use of our definition of care unit in nursing home research in the Canadian prairie provinces. Beyond research convenience however, the results also support the resident unit as an important Clinical Microsystem to which future interventions designed to improve resident quality of care and staff (healthcare aide) worklife should be targeted.

1981-01-01

The materials experiment carrier (MEC) is an optimized carrier for near term and advanced materials processing in space (MPS) research and commercial payloads. When coupled with the space platform (SP), the MEC can provide the extended duration, high power and low acceleration environment the MPS payload typically requires. The lowest cost, technically reasonable first step MEC that meets the MPS program missions objectives with minimum programmatic risks is defined. The effectiveness of the initial MEC/space platform idea for accommodating high priority, multidiscipline, R&D and commercial MPS payloads, and conducting MPS payload oprations at affordable funding and acceptable productivity levels is demonstrated.

Clarification of terminology in drug safety.

PubMed

Aronson, Jeffrey K; Ferner, Robin E

2005-01-01

Nomenclature surrounding drug safety needs to be clear and unambiguous, so that patients, prescribers, manufacturers, and regulators can all understand each other. In particular, it needs to make it clear how adverse events and drug therapy are related to one another, how they are best classified, and their frequency, intensity and seriousness. In this article, we therefore discuss and define terms used in the field of drug safety, particularly terms that are sometimes misunderstood or misused, including medicinal product, pharmaceutical formulation, excipient, adverse event (or experience) and adverse drug reaction (or effect). We also discuss terms used to define the seriousness, intensity, and risk of adverse reactions, and their classification. Instead of creating definitions from scratch, as is commonly done, we have taken the novel approach of critically examining definitions that have been proposed or widely used and have formulated new or modified definitions based on a logical appraisal of their merits and demerits. We hope that these definitions will lead to discussion that will allow a corpus of satisfactory definitions to be widely agreed.

Effects of focus and definiteness on children's word order: evidence from German five-year-olds' reproductions of double object constructions.

2014-07-01

Two experiments tested how faithfully German children aged 4 ;5 to 5 ;6 reproduce ditransitive sentences that are unmarked or marked with respect to word order and focus (Exp1) or definiteness (Exp2). Adopting an optimality theory (OT) approach, it is assumed that in the German adult grammar word order is ranked lower than focus and definiteness. Faithfulness of children's reproductions decreased as markedness of inputs increased; unmarked structures were reproduced most faithfully and unfaithful outputs had most often an unmarked form. Consistent with the OT proposal, children were more tolerant against inputs marked for word order than for focus; in conflict with the proposal, children were less tolerant against inputs marked for word order than for definiteness. Our results suggest that the linearization of objects in German double object constructions is affected by focus and definiteness, but that prosodic principles may have an impact on the position of a focused constituent.

Current Status of NASDA Terminology Database

NASDA Terminology Database System provides the English and Japanese terms, abbreviations, definition and reference documents. Recent progress includes a service to provide abbreviation data from the NASDA Home Page, and publishing a revised NASDA bilingual dictionary. Our next efforts to improve the system are (1) to combine our data with the data of NASA THESAURUS, (2) to add terms from new academic and engineering fields that have begun to have relations with space activities, and (3) to revise the NASDA Definition List. To combine our data with the NASA THESAURUS database we must consider the difference between the database concepts. Further effort to select adequate terms is thus required. Terms must be added from other fields to deal with microgravity experiments, human factors and so on. Some examples of new terms to be added have been collected. To revise the NASDA terms definition list, NASA and ESA definition lists were surveyed and a general concept to revise the NASDA definition list was proposed. I expect these activities will contribute to the IAA dictionary.

OBJECTIVES As part of the Closing the Quality Gap: Revisiting the State of the Science series of the Agency for Healthcare Research and Quality (AHRQ), this systematic review sought to identify completed and ongoing evaluations of the comprehensive patient-centered medical home (PCMH), summarize current evidence for this model, and identify evidence gaps. DATA SOURCES We searched PubMed®, CINAHL®, and the Cochrane Database of Systematic Reviews for published English-language studies, and a wide variety of databases and Web resources to identify ongoing or recently completed studies. REVIEW METHODS Two investigators per study screened abstracts and full-text articles for inclusion, abstracted data, and performed quality ratings and evidence grading. Our functional definition of PCMH was based on the definition used by AHRQ. We included studies that explicitly claimed to be evaluating PCMH and those that did not but which met our functional definition. RESULTS Seventeen studies with comparison groups evaluated the effects of PCMH (Key Question [KQ] 1). Older adults in the United States were the most commonly studied population (8 of 17 studies). PCMH interventions had a small positive impact on patient experiences (including patient-perceived care coordination) and small to moderate positive effects on preventive care services (moderate strength of evidence [SOE]). Staff experiences were also improved by a small to moderate degree (low SOE). There were too few studies to estimate effects on clinical or most economic outcomes. Twenty-one of 27 studies reported approaches that addressed all 7 major PCMH components (KQ 2), including team-based care, sustained partnership, reorganized care or structural changes to care, enhanced access, coordinated care, comprehensive care, and a systems-based approach to quality. A total of 51 strategies were used to address the 7 major PCMH components. Twenty-two of 27 studies reported information on financial systems used to implement PCMH, implementation strategies, and/or organizational learning strategies for implementing PCMH (KQ 3). The 31 studies identified in the horizon scan of ongoing PCMH studies (KQ 4) were broadly representative of the U.S. health care system, both in geography and in the complexity of private and public health care payers and delivery networks. CONCLUSIONS Published studies of PCMH interventions often have similar broad elements, but precise components of care varied widely. The PCMH holds promise for improving the experiences of patients and staff, and potentially for improving care processes. However, current evidence is insufficient to determine effects on clinical and most economic outcomes. Ongoing studies identified through the horizon scan have potential to greatly expand the evidence base relating to PCMH. PMID:24422946

A study on posttraumatic experience of road traffic accident afflicted maxillofacial trauma patient at tertiary hospital.

Patients are usually left in a vulnerable state after an accident. Because of this, they long for a good encounter when they are brought to the hospital. Physical impairment and psychological morbidities are some of the complications that can occur to them. Traditionally, surgeons tend to pay little attention to a patient's emotional and psychological perspective. The aim of this study was to understand the experience of oral and maxillofacial trauma patients due to road traffic accident right from immediate after the accident till the end of definitive treatment. Phenomenological approach of qualitative study was used to explore these patients' experience. Twenty subjects involved in road traffic accidents without any cognitive impairment aged 18 and above were recruited. Purposive sampling was used to include maximal variation sample regarding age, gender, types of injury, and types of treatment received. Semi-structured and open-ended interview approach was used to obtain in-depth information. Seven themes were identified to describe the patients' response to and experience after meeting with a road traffic accident; they are unreal experiences, emotional responses, need to inform and need for information, need for assistance, their perception toward the maxillofacial injury, their experience on treatment and staff-patient interaction. This qualitative study has provided an in-depth understanding of patients experience during maxillofacial trauma and treatment, which otherwise cannot be obtained by the use of surveys and test questions.

Experimental basis for a Titan probe organic analysis

1986-01-01

The recent Voyager flyby of Titan produced evidence for at least nine organic compounds in that atmosphere that are heavier than methane. Several models of Titan's atmosphere, as well as laboratory simulations, suggest the presence of organics considerably more complex that those observed. To ensure that the in situ measurements are definitive with respect to Titan's atmosphere, experiment concepts, and the related instrumentation, must be carefully developed specifically for such a mission. To this end, the possible composition of the environment to be analyzed must be bracketed and model samples must be provided for instrumentation development studies. Laboratory studies to define the optimum flight experiment and sampling strategy for a Titan entry probe are currently being conducted. Titan mixtures are being subjected to a variety of energy sources including high voltage electron from a DC discharge, high current electric shock, and laser detonation. Gaseous and solid products are produced which are then analyzed. Samples from these experiements are also provided to candidate flight experiments as models for instrument development studies. Preliminary results show that existing theoretical models for chemistry in Titan's atmosphere cannot adequetely explain the presence and abundance of all trace gases observed in these experiments.

Do individual differences in children's curiosity relate to their inquiry-based learning?

This study investigates how individual differences in 7- to 9-year-olds' curiosity relate to the inquiry-learning process and outcomes in environments differing in structure. The focus on curiosity as individual differences variable was motivated by the importance of curiosity in science education, and uncertainty being central to both the definition of curiosity and the inquiry-learning environment. Curiosity was assessed with the Underwater Exploration game (Jirout, J., & Klahr, D. (2012). Children's scientific curiosity: In search of an operational definition of an elusive concept. Developmental Review, 32, 125-160. doi:10.1016/j.dr.2012.04.002), and inquiry-based learning with the newly developed Scientific Discovery task, which focuses on the principle of designing informative experiments. Structure of the inquiry-learning environment was manipulated by explaining this principle or not. As intelligence relates to learning and possibly curiosity, it was taken into account. Results showed that children's curiosity was positively related to their knowledge acquisition, but not to their quality of exploration. For low intelligent children, environment structure positively affected their quality of exploration, but not their knowledge acquisition. There was no interaction between curiosity and environment structure. These results support the existence of two distinct inquiry-based learning processes - the designing of experiments, on the one hand, and the reflection on performed experiments, on the other - and link children's curiosity to the latter process.

We examine experiences of collective self-objectification (CSO) (or its failure) among participants in a 'multicultural' St Patrick's Day parade. A two-stage interview study was carried out in which 10 parade participants (five each from ethnic majority and minority groups) were interviewed before and after the event. In pre-event interviews, all participants understood the parade as an opportunity to enact social identities, but differed in the category definitions and relations they saw as relevant. Members of the white Irish majority saw the event as being primarily about representing Ireland in a positive, progressive, light, whereas members of minority groups saw it as an opportunity to have their groups' identities and belonging in Ireland recognized by others. Post-event interviews revealed that, for the former group, the event succeeded in giving expression to their relevant category definitions. The latter group, on the other hand, cited features of the event such as inauthentic costume design and a segregated structure as reasons for why the event did not provide the group recognition they sought. The accounts revealed a variety of empowering and disempowering experiences corresponding to the extent of enactment. We consider the implications in terms of CSO, the performative nature of dual identities, as well as the notion of multicultural recognition. © 2013 The British Psychological Society.

It is obviously impossible to draw definite conclusions as to the significance of the differences between our work and Gye's, and still less, of the differences between Gye's work and that of Murphy and of Flu. We can only say that in a fairly large series of experiments, extending over a period of 12 months, we have had absolutely no indication of the necessity of two factors in the production of the Rous sarcoma. In other words, we have been unable to duplicate either the results of Gye or the modified confirmations of his work by Murphy and Flu. We have shown that uncontrollable local and individual variations may produce results in occasional chicks which simulate satisfactory experiments, but when viewed as a whole, mean nothing. Because of the conflicting nature of results obtained by those who have undertaken to repeat the work, and on account of the difficulty of controlling all factors involved, we do not feel that it may be stated definitely that Gye's theory of the cause of cancer is wrong. On the other hand the theory apparently needs more evidence in its support if it is to receive further serious consideration. It is suggested, in order to untangle the subjéct as rapidly as possible, that future publications should include sufficient consecutive protocols to make the trend of the experiments obvious to the reader.

The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation developed the first evidence-based definition for lifelong premature ejaculation (PE) in 2007 and concluded that there were insufficient published objective data at that time to develop a definition for acquired PE. The aim of this article is to review and critique the current literature and develop a contemporary, evidence-based definition for acquired PE and/or a unified definition for both lifelong and acquired PE. In April 2013, the ISSM convened a second Ad Hoc Committee for the Definition of Premature Ejaculation in Bangalore, India. The same evidence-based systematic approach to literature search, retrieval, and evaluation used by the original committee was adopted. The committee unanimously agreed that men with lifelong and acquired PE appear to share the dimensions of short ejaculatory latency, reduced or absent perceived ejaculatory control, and the presence of negative personal consequences. Men with acquired PE are older, have higher incidences of erectile dysfunction, comorbid disease, and cardiovascular risk factors, and have a longer intravaginal ejaculation latency time (IELT) as compared with men with lifelong PE. A self-estimated or stopwatch IELT of 3 minutes was identified as a valid IELT cut-off for diagnosing acquired PE. On this basis, the committee agreed on a unified definition of both acquired and lifelong PE as a male sexual dysfunction characterized by (i) ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE); (ii) the inability to delay ejaculation on all or nearly all vaginal penetrations; and (iii) negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. The ISSM unified definition of lifelong and acquired PE represents the first evidence-based definition for these conditions. This definition will enable researchers to design methodologically rigorous studies to improve our understanding of acquired PE.

The trans-Pacific high data rate (TP-HDR) satellite communications experiment was proposed at the Japan-U.S. Cooperation in Space (JUCS) Program Workshop held in Hawaii in 1993 and remote high definition video post-production was demonstrated as the first phase trial. Following the first phase, the second phase experiment is currently prepared. This paper describes the experimental network configuration, application demonstration, and performance evaluation plan of the second phase experiment.

Conversation analysis can take the form of a qualitative methodology for the exploration of discursive productions, whose main goal is the formulation of hypotheses for reading psychosocial interaction through descriptive models of interlocution. Therefore, in this study, conversations in a shared Virtual Environment have been analyzed in order to understand the specific structure, dynamics, and phenomenology of Virtual Reality effects on the "interactive micro-chains" that constitute the communicative thread of daily experience.

The boundaries of wilderness areas have traditionally been defined based on the management authorities' perceptions of which areas have wilderness quality. Experience shows that many areas classified as wilderness do not actually have wilderness qualities and do not provide a true...

Applications of a job classification system in occupational epidemiology.

Gamble, J F; Spirtas, R; Easter, P

An occupational preventive medicine program attempts to control exposure so workers experience no detrimental effect on health. In a chemically complex industry, the definition of exposure is difficult because of the many different chemicals used and produced, the many different jobs and processes with qualitatively different exposures, and the movement of workers from job to job. Jobs have therefore been grouped on the basis of process or product into functionally homogeneous categories called occupational titles (OT's). Work experience can now be quantified independent of exposure (or by the dominant toxicants in each OT) and compared to health outcomes. Examples are discussed of the application of OT's to studies of the mortality and morbidity experience in the rubber industry, and the development of dose-response relations. PMID:961945
