Model-Invariant Hybrid Computations of Separated Flows for RCA Standard Test Cases

NASA Technical Reports Server (NTRS)

Woodruff, Stephen

2016-01-01

NASA's Revolutionary Computational Aerosciences (RCA) subproject has identified several smooth-body separated flows as standard test cases to emphasize the challenge these flows present for computational methods and their importance to the aerospace community. Results of computations of two of these test cases, the NASA hump and the FAITH experiment, are presented. The computations were performed with the model-invariant hybrid LES-RANS formulation, implemented in the NASA code VULCAN-CFD. The model- invariant formulation employs gradual LES-RANS transitions and compensation for model variation to provide more accurate and efficient hybrid computations. Comparisons revealed that the LES-RANS transitions employed in these computations were sufficiently gradual that the compensating terms were unnecessary. Agreement with experiment was achieved only after reducing the turbulent viscosity to mitigate the effect of numerical dissipation. The stream-wise evolution of peak Reynolds shear stress was employed as a measure of turbulence dynamics in separated flows useful for evaluating computations.

Serial position effects in recognition memory for odors: a reexamination.

PubMed

Miles, Christopher; Hodder, Kathryn

2005-10-01

Seven experiments examined recognition memory for sequentially presented odors. Following Reed (2000), participants were presented with a sequence of odors and then required to identify an odor from the sequence in a test probe comprising 2 odors. The pattern of results obtained by Reed (2000, although statistically marginal) demonstrated enhanced recognition for odors presented at the start (primacy) and end (recency) of the sequence: a result that we failed to replicate in any of the experiments reported here. Experiments 1 and 3 were designed to replicate Reed (2000), employing five-item and seven-item sequences, respectively, and each demonstrated significant recency, with evidence of primacy in Experiment 3 only. Experiment 2 replicated Experiment 1, with reduced interstimulus intervals, and produced a null effect of serial position. The ease with which the odors could be verbally labeled was manipulated in Experiments 4 and 5. Nameable odors produced a null effect of serial position (Experiment 4), and hard-to-name odors produced a pronounced recency effect (Experiment 5); nevertheless, overall rates of recognition were remarkably similar for the two experiments at around 70%. Articulatory suppression reduced recognition accuracy (Experiment 6), but recency was again present in the absence of primacy. Odor recognition performance was immune to the effects of an interleaved odor (Experiment 7), and, again, both primacy and recency effects were absent. There was no evidence of olfactory fatigue: Recognition accuracy improved across trials (Experiment 1). It is argued that the results of the experiments reported here are generally consistent with that body of work employing hard-to-name visual stimuli, where recency is obtained in the absence of primacy when the retention interval is short.

Performance under dichoptic versus binocular viewing conditions - Effects of attention and task requirements

NASA Technical Reports Server (NTRS)

Kimchi, Ruth; Gopher, Daniel; Rubin, Yifat; Raij, David

1993-01-01

Three experiments investigated subjects' ability to allocate attention and cope with task requirements under dichoptic versus binocular viewing conditions. Experiments 1 and 2 employed a target detection task in compound and noncompound stimuli, and Experiment 3 employed a relative-proximity judgment task. The tasks were performed in a focused attention condition in which subjects had to attend to the stimulus presented to one eye or field (under dichoptic and binocular viewing conditions, respectively) while ignoring the stimulus presented to the other eye or field, and in a divided attention condition in which subjects had to attend to the stimuli presented to both eyes or fields. Subjects' performance was affected by the interaction of attention conditions with task requirements, but it was generally the same under dichoptic and binocular viewing conditions. The more dependent the task was on finer discrimination, the more performance was impaired by divided attention. These results suggest that at least with discrete tasks and relatively short exposure durations, performance when each eye is presented with a separate stimulus is the same as when the entire field of stimulation is viewed by both eyes.

Empirical Evidence on Occupation and Industry Specific Human Capital

PubMed Central

Sullivan, Paul

2009-01-01

This paper presents instrumental variables estimates of the effects of firm tenure, occupation specific work experience, industry specific work experience, and general work experience on wages using data from the 1979 Cohort of the National Longitudinal Survey of Youth. The estimates indicate that both occupation and industry specific human capital are key determinants of wages, and the importance of various types of human capital varies widely across one-digit occupations. Human capital is primarily occupation specific in occupations such as craftsmen, where workers realize a 14% increase in wages after five years of occupation specific experience but do not realize wage gains from industry specific experience. In contrast, human capital is primarily industry specific in other occupations such as managerial employment where workers realize a 23% wage increase after five years of industry specific work experience. In other occupations, such as professional employment, both occupation and industry specific human capital are key determinants of wages. PMID:20526448

Planned LMSS propagation experiment using ACTS: Preliminary antenna pointing results during mobile operations

NASA Technical Reports Server (NTRS)

Rowland, John R.; Goldhirsh, Julius; Vogel, Wolfhard J.; Torrence, Geoffrey W.

1991-01-01

An overview and a status description of the planned LMSS mobile K band experiment with ACTS is presented. As a precursor to the ACTS mobile measurements at 20.185 GHz, measurements at 19.77 GHz employing the Olympus satellite were originally planned. However, because of the demise of Olympus in June of 1991, the efforts described here are focused towards the ACTS measurements. In particular, we describe the design and testing results of a gyro controlled mobile-antenna pointing system. Preliminary pointing measurements during mobile operations indicate that the present system is suitable for measurements employing a 15 cm aperture (beamwidth at approximately 7 deg) receiving antenna operating with ACTS in the high gain transponder mode. This should enable measurements with pattern losses smaller than plus or minus 1 dB over more than 95 percent of the driving distance. Measurements with the present mount system employing a 60 cm aperture (beamwidth at approximately 1.7 deg) results in pattern losses smaller than plus or minus 3 dB for 70 percent of the driving distance. Acceptable propagation measurements may still be made with this system by employing developed software to flag out bad data points due to extreme pointing errors. The receiver system including associated computer control software has been designed and assembled. Plans are underway to integrate the antenna mount with the receiver on the University of Texas mobile receiving van and repeat the pointing tests on highways employing a recently designed radome system.

Optical proposals for controlled delayed-choice experiment based on weak cross-Kerr nonlinearities

NASA Astrophysics Data System (ADS)

Dong, Li; Lin, Yan-Fang; Li, Qing-Yang; Xiu, Xiao-Ming; Dong, Hai-Kuan; Gao, Ya-Jun

2017-05-01

Employing polarization modes of a photon, we propose two theoretical proposals to exhibit the wave-particle duality of the photon with the assistance of weak cross-Kerr nonlinearities. The first proposal is a classical controlled delayed-choice experiment (that is, Wheeler's delayed-choice experiment), where we can observe selectively wave property or particle property of the photon relying on the experimenter's selection, whereas the second proposal is a quantum controlled delayed-choice experiment, by which the mixture phenomenon of a wave and a particle will be exhibited. Both of them can be realized with near-unity probability and embody the charming characteristics of quantum mechanics. The employment of the mature techniques and simple operations (e.g., Homodyne measurement, classical feed forward, and single-photon transformations) provides the feasibility of the delayed-choice experiment proposals presented here.

Personal experiences of people with serious mental illness when seeking, obtaining and maintaining competitive employment in Queensland, Australia.

PubMed

Gladman, Beverley; Waghorn, Geoff

2016-02-15

High non-participation in the labour force and unemployment remain challenging for adults with serious mental illness. This study examined the personal experiences of people with serious mental illness when seeking, obtaining and maintaining competitive employment. The aim was to increase understanding of personal experiences of employment and how these experiences can be used to inform the assistance provided in support of clients' competitive employment goals. Qualitative data from a two-year period were thematically analysed from one participating site in a multi-site trial of employment services integrated with public funded community mental health treatment and care. Both positive and negative themes arose. Positive themes included: Aspirations for a better life, receiving feedback on good job performance, employment displacing preoccupation with illness, and employment improving self-esteem and reducing financial stress. Negative themes included stigma experiences, stress, and health difficulties. Both positive and negative experiences did not depend on type of employment service assistance nor key client characteristics such as age, sex, and diagnostic category. Despite its many benefits, employment can also increase the risk of negative personal experiences. These findings suggest that employment service providers could do more to assist people who commence employment, to reduce the risk of negative personal experiences and to enhance the benefits of competitive employment.

'Quantum interference with slits' revisited

NASA Astrophysics Data System (ADS)

Rothman, Tony; Boughn, Stephen

2011-01-01

Marcella has presented a straightforward technique employing the Dirac formalism to calculate single- and double-slit interference patterns. He claims that no reference is made to classical optics or scattering theory and that his method therefore provides a purely quantum mechanical description of these experiments. He also presents his calculation as if no approximations are employed. We show that he implicitly makes the same approximations found in classical treatments of interference and that no new physics has been introduced. At the same time, some of the quantum mechanical arguments Marcella gives are, at best, misleading.

Quantifying the transport properties of lipid mesophases by theoretical modelling of diffusion experiments

NASA Astrophysics Data System (ADS)

Antognini, Luca M.; Assenza, Salvatore; Speziale, Chiara; Mezzenga, Raffaele

2016-08-01

Lyotropic Liquid Crystals (LLCs) are a class of lipid-based membranes with a strong potential for drug-delivery employment. The characterization and control of their transport properties is a central issue in this regard, and has recently prompted a notable volume of research on the topic. A promising experimental approach is provided by the so-called diffusion setup, where the drug molecules diffuse from a feeding chamber filled with water to a receiving one passing through a LLC. In the present work we provide a theoretical framework for the proper description of this setup, and validate it by means of targeted experiments. Due to the inhomogeneity of the system, a rich palette of different diffusion dynamics emerges from the interplay of the different time- and lengthscales thereby present. Our work paves the way to the employment of diffusion experiments to quantitatively characterize the transport properties of LLCs, and provides the basic tools for device diffusion setups with controlled kinetic properties.

A Survey of Athletic Training Employers' Hiring Criteria

PubMed Central

Andrews, Lanna

2001-01-01

Objective: To identify athletic training employers' hiring criteria and to determine if the importance of individual hiring criteria vary by setting. Design and Setting: The Athletic Training Employer Needs Assessment Survey was mailed to athletic training employers advertising in the National Athletic Trainers' Association (NATA) placement vacancy notice between October 1996 and October 1998. Subjects: A total of 111 athletic training employers in NATA Districts 7, 8, and 10 were surveyed. Measurements: Employers rated the importance of hiring criteria on a 7-point Likert scale. Means and standard deviations were calculated for each criterion and compared these values to ascertain the importance of individual criteria. A principal component analysis was done to determine the underlying factors. Results: Hiring characteristics can be divided into 4 factors that include highly related criteria: (1) personal characteristics, (2) educational experience, (3) professional experience, and (4) work-related attributes. In addition, the hiring characteristics desired by employers varied among athletic training settings. Conclusions: When interviewing and presenting themselves for entry-level positions, athletic trainers should pay particular attention to the attributes within the 4 hiring criteria factors. Also, the desired hiring criteria of athletic training employers differed by setting. Applicants need to pay particular attention to these hiring criteria differences when constructing résumés, cover letters, and professional correspondence and when interviewing with prospective employers.

This presentation describes two shuttle Get-Away-Special (GAS) experiments built by McDonnell Douglas to investigate low-g propellant acquisition and gaging. The first experiment was flown on shuttle mission 41-G in October 1984. The second experiment has been qualified for flight and is waiting for a flight assignment. The tests performed to qualify these experiments for flight are described, and the lessons learned which can be applied to future GAS experiments are discussed. Finally, survey results from 134 GAS experiments flown to date are presented. On the basis of these results it is recommended that future GAS experiments be qualified to shuttle thermal and dynamic environments through a rigorous series of mission operating tests. Furthermore, should automatic activation of the experiment be required during the boost phase of the mission, NASA-supplied redundant barometric switches should be employed to trigger the activation.

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.

The experiences of women engineers who have completed one to five years of professional engineering employment: A phenomenological study

NASA Astrophysics Data System (ADS)

White, Susan M.

Women engineers remain underrepresented in employment in engineering fields in the United States. Feminist theory views this gender disparity beyond equity in numbers for women engineers and looks at structural issues of women's access, opportunities, and quality of experience in the workplace. Research on women's success and persistence in engineering education is diverse; however, there are few studies that focus on the early years of women's careers in engineering and less using a phenomenological research design. Experiences of women engineers who have completed one to five years of professional engineering employment are presented using a phenomenological research design. Research questions explored the individual and composite experiences for the co-researchers of the study as well as challenges and advantages of the phenomenon of having completed one to five years of professional engineering employment. Themes that emanated from the data were a feeling that engineering is a positive profession, liking math and science from an early age, having experiences of attending math and science camps or learning and practicing engineering interests with their fathers for some co-researchers. Other themes included a feeling of being different as a woman in the engineering workplace, taking advantage of opportunities for training, education, and advancement to further their careers, and the role of informal and formal mentoring in developing workplace networks and engineering expertise. Co-researchers negotiated issues of management quality and support, experiences of gender discrimination in the workplace, and having to make decisions balancing their careers and family responsibilities. Finally, the women engineers for this research study expressed intentions to persist in their careers while pursuing expertise and experience in their individual engineering fields.

Examining the Professional Development Experiences and Non-Technical Skills Desired for Geoscience Employment

NASA Astrophysics Data System (ADS)

Houlton, H. R.; Ricci, J.; Wilson, C. E.; Keane, C.

2014-12-01

Professional development experiences, such as internships, research presentations and professional network building, are becoming increasingly important to enhance students' employability post-graduation. The practical, non-technical skills that are important for succeeding during these professional development experiences, such as public speaking, project management, ethical practices and writing, transition well and are imperative to the workplace. Thereby, graduates who have honed these skills are more competitive candidates for geoscience employment. Fortunately, the geoscience community recognizes the importance of these professional development opportunities and the skills required to successfully complete them, and are giving students the chance to practice non-technical skills while they are still enrolled in academic programs. The American Geosciences Institute has collected data regarding students' professional development experiences, including the preparation they receive in the corresponding non-technical skills. This talk will discuss the findings of two of AGI's survey efforts - the Geoscience Student Exit Survey and the Geoscience Careers Master's Preparation Survey (NSF: 1202707). Specifically, data highlighting the role played by internships, career opportunities and the complimentary non-technical skills will be discussed. As a practical guide, events informed by this research, such as AGI's professional development opportunities, networking luncheons and internships, will also be included.

A research using hybrid RBF/Elman neural networks for intrusion detection system secure model

NASA Astrophysics Data System (ADS)

Tong, Xiaojun; Wang, Zhu; Yu, Haining

2009-10-01

A hybrid RBF/Elman neural network model that can be employed for both anomaly detection and misuse detection is presented in this paper. The IDSs using the hybrid neural network can detect temporally dispersed and collaborative attacks effectively because of its memory of past events. The RBF network is employed as a real-time pattern classification and the Elman network is employed to restore the memory of past events. The IDSs using the hybrid neural network are evaluated against the intrusion detection evaluation data sponsored by U.S. Defense Advanced Research Projects Agency (DARPA). Experimental results are presented in ROC curves. Experiments show that the IDSs using this hybrid neural network improve the detection rate and decrease the false positive rate effectively.

2017-01-01

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

Factors that influence the tribocharging of pulverulent materials in compressed-air devices

Das, S.; Medles, K.; Mihalcioiu, A.; Beleca, R.; Dragan, C.; Dascalescu, L.

2008-12-01

Tribocharging of pulverulent materials in compressed-air devices is a typical multi-factorial process. This paper aims at demonstrating the interest of using the design of experiments methodology in association with virtual instrumentation for quantifying the effects of various process varaibles and of their interactions, as a prerequisite for the development of new tribocharging devices for industrial applications. The study is focused on the tribocharging of PVC powders in compressed-air devices similar to those employed in electrostatic painting. A classical 2 full-factorial design (3 factors at two levels) was employed for conducting the experiments. The response function was the charge/mass ratio of the material collected in a modified Faraday cage, at the exit of the tribocharging device. The charge/mass ratio was found to increase with the injection pressure and the vortex pressure in the tribocharging device, and to decrease with the increasing of the feed rate. In the present study an in-house design of experiments software was employed for statistical analysis of experimental data and validation of the experimental model.

The use of visual cues in gravity judgements on parabolic motion.

PubMed

Jörges, Björn; Hagenfeld, Lena; López-Moliner, Joan

2018-06-21

Evidence suggests that humans rely on an earth gravity prior for sensory-motor tasks like catching or reaching. Even under earth-discrepant conditions, this prior biases perception and action towards assuming a gravitational downwards acceleration of 9.81 m/s 2 . This can be particularly detrimental in interactions with virtual environments employing earth-discrepant gravity conditions for their visual presentation. The present study thus investigates how well humans discriminate visually presented gravities and which cues they use to extract gravity from the visual scene. To this end, we employed a Two-Interval Forced-Choice Design. In Experiment 1, participants had to judge which of two presented parabolas had the higher underlying gravity. We used two initial vertical velocities, two horizontal velocities and a constant target size. Experiment 2 added a manipulation of the reliability of the target size. Experiment 1 shows that participants have generally high discrimination thresholds for visually presented gravities, with weber fractions of 13 to beyond 30%. We identified the rate of change of the elevation angle (ẏ) and the visual angle (θ) as major cues. Experiment 2 suggests furthermore that size variability has a small influence on discrimination thresholds, while at the same time larger size variability increases reliance on ẏ and decreases reliance on θ. All in all, even though we use all available information, humans display low precision when extracting the governing gravity from a visual scene, which might further impact our capabilities of adapting to earth-discrepant gravity conditions with visual information alone.

Abstract: Presently, there exists no published valid and reliable salary study of clinical perfusionists. The objective of the 2015 Perfusionist Salary Study was to gather verifiable employee information to determine current compensation market rates (salary averages) of clinical perfusionists working in the United States. A salary survey was conducted between April 2015 and March 2016. The survey required perfusionists to answer questions about work volume, scheduling, and employer-paid compensation including benefits. Participants were also required to submit a de-identified pay stub to validate the income they reported. Descriptive statistics were calculated for all survey questions (e.g., percentages, means, and ranges). The study procured 481 responses, of which 287 were validated (i.e., respondents provided income verification that matched reported earnings). Variables that were examined within the validated sample population include job title, type of institution of employment, education level, years of experience, and geographic region, among others. Additional forms of compensation which may affect base compensation rates were also calculated including benefits, call time, bonuses, and pay for ancillary services (e.g., extracorporeal membrane oxygenation and ventricular assist device). In conclusion, in 2015, the average salary for all perfusionists is $127,600 with 19 years' experience. This research explores the average salary within subpopulations based on other factors such as position role, employer type, and geography. Information from this study is presented to guide employer compensation programs and suggests the need for further study in consideration of attrition rates and generational changes (i.e., perfusionists reaching retirement age) occurring alongside the present perfusionist staffing shortage affecting many parts of the country.

Twelve years' experience in providing summer employment for students in official health agencies in British Columbia is reviewed and a two-week orientation course given prior to employment in 1964 is described. In the program, which provides experience in teaching, research and community service, a total of 43 students have been employed. Students seeking this type of employment and accepted for it tend to have high academic standing. They prefer employment in or near Vancouver irrespective of their original home location. Two main employers have been available: specialized agencies in metropolitan Vancouver, or “rural” health units. Students serving in health units showed a strong tendency to enter general practice after graduation. Urban experience tended to lead to specialization. PMID:14278027

African-Americans shoulder an excessive burden of unemployment, precarious employment, and low paying jobs in the United States, which may help explain why they experience some of the worst health outcomes among U.S. citizens. This paper presents a conceptual framework describing this phenomenon. The social determinants of health as described by this framework include racism, social and public policy formation, socioeconomic status, and conditions of employment. The intermediate determinants of health, which include the ability to afford health behavior, depression and addiction, environmental exposures, and access to primary care, are informed by conditions of employment, which leads to poor health outcomes for African-Americans. This paper will explore in detail these relationships. © 2015 Wiley Periodicals, Inc.

Whitehouse, Andrew J O; Maybery, Murray T; Durkin, Kevin

2006-08-01

Three experiments investigated the role of inner speech deficit in cognitive performances of children with autism. Experiment 1 compared children with autism with ability-matched controls on a verbal recall task presenting pictures and words. Experiment 2 used pictures for which the typical names were either single syllable or multisyllable. Two encoding conditions manipulated the use of verbal encoding. Experiment 3 employed a task-switching paradigm for which performance has been shown to be contingent upon inner speech. In Experiment 1, children with autism demonstrated a lower picture-superiority effect compared to controls. In Experiment 2, the children with autism showed a lower word-length effect when pictures were presented alone, but a more substantial word-length effect in a condition requiring overt labelling. In Experiment 3, articulatory suppression affected the task-switching performance of the control participants only. Individuals with autism have limitations in their use of inner speech.

Purpose This article presents new evidence on employment barriers and workplace disparities facing employees with disabilities, linking the disparities to employee attitudes. Methods Analyses use the 2006 General Social Survey to connect disability to workplace disparities and attitudes in a structural equation model. Results Compared to employees without disabilities, those with disabilities report: lower pay levels, job security, and flexibility; more negative treatment by management; and, lower job satisfaction but similar organizational commitment and turnover intention. The lower satisfaction is mediated by lower job security, less job flexibility, and more negative views of management and co-worker relations. Conclusion Prior research and the present findings show that people with disabilities experience employment disparities that limit their income, security, and overall quality of work life. Technology plays an increasingly important role in decreasing employment disparities. However, there also should be increased targeted efforts by government, employers, insurers, occupational rehabilitation providers, and disability groups to address workplace barriers faced by employees with disabilities, and by those with disabilities seeking to return to work.

The "emotion misattribution" procedure: processing beyond good and bad under masked and unmasked presentation conditions.

PubMed

Rohr, Michaela; Degner, Juliane; Wentura, Dirk

2015-01-01

In general, it is assumed that misattribution in the Affect Misattribution Procedure (AMP) is restricted to crude affect due to its unbound nature, especially under limited presentation conditions. In two experiments, we investigated whether emotion-specific misattributions occur using a four-category misattribution procedure. Experiment 1 yielded emotion-specific misattribution effects under clearly visible presentation conditions demonstrating that the procedure is principally susceptible for emotion-specific effects. In Experiment 2, we employed masked presentation conditions impeding conscious prime perception. A specific pattern of emotion-specific misattributions effects emerged indicating some emotion-specific processing at initial stages of processing. However, not each emotion was misattributed equally. We discuss the implications of these results for the non-conscious processing of emotional information, for the supposed mechanisms of the AMP and its implicit nature.

2018-04-01

This scoping review presents an exploration of international literature on the factors that impact refugees' personal and professional experiences during their journey to being registered nurses in a new host country. Governments of host countries receiving refugees seek to develop strategies that facilitate the successful resettlement, employment and enculturation of refugees that arrive as skilled professionals. There is a scarcity of studies focussing on issues faced by refugees that are RNs or those pursuing nursing registration and employment in a new host country. This study is relevant for resettlement services, nursing registration authorities and education providers and informs the international nursing workforce. Scoping review. Databases such as MEDLINE, EMBASE, Cochrane Library, CINAHL; Google Scholar; PubMed; Scopus and Web of Science were searched for qualitative studies published up to and including 2017. Articles that did not specify explicitly the participants as registered nurses and/or refugees were excluded. All eligible articles were analysed for collective findings, and impact factors were extracted, synthesised and illustrated diagrammatically. This review explored six eligible articles and six impact factors were identified. The challenging impacts were as follows: loss of control; shock in a new environment and bleak employment prospects. Equally three impact factors: reconciling new reality; establishing a new identity and hope for the future, facilitate positive experiences for nurses in their successful transition into society and the nursing workplace. This scoping review reports the small number of international studies on the experiences of refugees seeking to become registered and employed as registered nurses. The six impact factors identified influence the lives of the nurse participants socio-economically in and out of the workplace. Policymakers, managers and educators providing resettlement, registration and employment services could develop strategies that enhance integration and transition experiences of refugees aspiring to be registered nurses. © 2018 John Wiley & Sons Ltd.

In this presentation, we will introduce five experiments and hands-on activities for geoscience observing and measuring by using low-priced and small-sized commercial instruments. The Black Box for Environmental Measuring (BBEM) system is based on Arduino platform, low-power consumption sensors are employed to measure meteorological and environmental parameters. Commercial GPS receiver is used to observe the influence of geomagnetic storms on GPS system. Webcam is an accessible instrument which is suitable for detecting and recording sprites, thunders, and the development of cumulonimbus. Real-time flight trackers and websites are employed to determine the altitude of cloud base. A simple VLF receiver is built by using the audio interface on computer, and the observed signals showed the variations of the D-region of the ionosphere. All these experiments and activities are practical and have been applied in classroom and science outreach in Taiwan.

Sensitivity enhancements in MQ-MAS NMR of spin-5/2 nuclei using modulated rf mixing pulses

NASA Astrophysics Data System (ADS)

Vosegaard, Thomas; Massiot, Dominique; Grandinetti, Philip J.

2000-08-01

An X- overlineX pulse train with stepped modulation frequency was employed to enhance the multiple-quantum to single-quantum coherence transfer in the mixing period of the multiple-quantum magic-angle spinning (MQ-MAS) experiment for spin I=5/2 nuclei. Two MQ-MAS pulse sequences employing this mixing scheme for the triple-to-single and quintuple-to-single quantum coherence transfers have been designed and their performance is demonstrated for 27Al on samples of NaSi 3AlO 8 and 9Al 2O 3·2B 2O 3 . Compared to the standard single-pulse mixing sequences, the sensitivity is approximately doubled in the present experiments.

Shape control of an adaptive wing for transonic drag reduction

NASA Astrophysics Data System (ADS)

Austin, Fred; Van Nostrand, William C.

1995-05-01

Theory and experiments to control the static shape of flexible structures by employing internal translational actuators are summarized and plants to extend the work to adaptive wings are presented. Significant reductions in the shock-induced drag are achievable during transonic- cruise by small adaptive modifications to the wing cross-sectional profile. Actuators are employed as truss elements of active ribs to deform the wing cross section. An adaptive-rib model was constructed, and experiments validated the shape-control theory. Plans for future development under an ARPA/AFWAL contract include payoff assessments of the method on an actual aircraft, the development of inchworm TERFENOL-D actuators, and the development of a method to optimize the wing cross-sectional shapes by direct-drag measurements.

Examining lateralized semantic access using pictures.

PubMed

Lovseth, Kyle; Atchley, Ruth Ann

2010-03-01

A divided visual field (DVF) experiment examined the semantic processing strategies employed by the cerebral hemispheres to determine if strategies observed with written word stimuli generalize to other media for communicating semantic information. We employed picture stimuli and vary the degree of semantic relatedness between the picture pairs. Participants made an on-line semantic relatedness judgment in response to sequentially presented pictures. We found that when pictures are presented to the right hemisphere responses are generally more accurate than the left hemisphere for semantic relatedness judgments for picture pairs. Furthermore, consistent with earlier DVF studies employing words, we conclude that the RH is better at accessing or maintaining access to information that has a weak or more remote semantic relationship. We also found evidence of faster access for pictures presented to the LH in the strongly-related condition. Overall, these results are consistent with earlier DVF word studies that argue that the cerebral hemispheres each play an important and separable role during semantic retrieval.

2017-10-01

At the beginning, HEP experiments made use of photographical images both to record and store experimental data and to illustrate their findings. Then the experiments evolved and needed to find ways to visualize their data. With the availability of computer graphics, software packages to display event data and the detector geometry started to be developed. Here, an overview of the usage of event display tools in HEP is presented. Then the case of the ATLAS experiment is considered in more detail and two widely used event display packages are presented, Atlantis and VP1, focusing on the software technologies they employ, as well as their strengths, differences and their usage in the experiment: from physics analysis to detector development, and from online monitoring to outreach and communication. Towards the end, the other ATLAS visualization tools will be briefly presented as well. Future development plans and improvements in the ATLAS event display packages will also be discussed.

Utilizing Controlled Vibrations in a Microgravity Environment to Understand and Promote Microstructural Homogeneity During Floating-Zone Crystal Growth

Anilkumar, A. V.; Bhowmick, J.; Grugel, R. N.

2001-01-01

Our previous experiments with NaNO3 float-zones revealed that steady thermocapillary flow can be balanced/offset by the controlled surface streaming flow induced by end-wall vibration. In the current experiments we are examining the effects of streaming flow on steadying/stabilizing nonsteady thermocapillary flow in such zones. To this effect we have set up a controlled NaNO3 half-zone experiment, where the processing parameters, like zone dimensions and temperature gradients, can be easily varied to generate nonsteady thermocapillary flows. In the present paper we present preliminary results of our investigations into stabilizing such flows by employing endwall vibration.

van Wüllen, Leo; Tricot, Grégory; Wegner, Sebastian

2007-10-01

In this work a combination of complementary advanced solid-state nuclear magnetic resonance (NMR) strategies is employed to analyse the network organization in aluminophosphate glasses to an unprecedented level of detailed insight. The combined results from MAS, MQMAS and (31)P-{(27)Al}-CP-heteronuclear correlation spectroscopy (HETCOR) NMR experiments allow for a detailed speciation of the different phosphate and aluminate species present in the glass. The interconnection of these local building units to an extended three-dimensional network is explored employing heteronuclear dipolar and scalar NMR approaches to quantify P-O-Al connectivity by (31)P{(27)Al}-heteronuclear multiple quantum coherence (HMQC), -rotational echo adiabatic passage double resonance (REAPDOR) and -HETCOR NMR as well as (27)Al{(31)P}-rotational echo double resonance (REDOR) NMR experiments, complemented by (31)P-2D-J-RESolved MAS NMR experiments to probe P-O-P connectivity utilizing the through bond scalar J-coupling. The combination of the results from the various NMR approaches enables us to not only quantify the phosphate units present in the glass but also to identify their respective structural environments within the three-dimensional network on a medium length scale employing a modified Q notation, Q(n)(m),(AlO)(x), where n denotes the number of connected tetrahedral phosphate, m gives the number of aluminate species connected to a central phosphate unit and x specifies the nature of the bonded aluminate species (i.e. 4, 5 or 6 coordinate aluminium).

Psychosocial risk among migrant workers: what we can learn from literature and field experiences.

PubMed

Porru, S; Elmetti, S; Arici, Cecilia

2014-01-01

Mental health problems are possible in migrant workers (MWs), who are mainly employed in dangerous jobs and face many barriers to prevention and care. To outline current scientific evidence about psychosocial risk among MWs; to present data from clinical and field experiences. Non-systematic literature review (PubMed, last 10 years); case series of 20 MWs, evaluated for mental and/or behavioural disorders at a public occupational health unit; applied field research, in enterprise contexts. A relatively low number of publications about psychosocial risk among MWs was found. Individual migrants may find the experience of migration to be stressful, with increased rates of depression and/or anxiety disorders. Data from clinical case series suggest that MWs from some ethnic groups, with a medium-high level of education, employed in metal or manufacturing industries, might have an increased risk of developing psychiatric disorders. Preliminary data from our field study seem to confirm that MWs, predominantly employed in unskilled/manual jobs and more prone to work overtime, tend to present higher prevalence of psychiatric disorders. There is a growing need to improve the scientific knowledge on migration, work, and mental health, as well as to promote workplace prevention of mental disorders in MWs. This can be achieved also by reducing structural barriers to mental wellbeing: in particular, occupational physicians should answer to MWs' mental health needs, contributing both to diagnosis and management of MWs' work-related psychiatric disorders.

Employment programs and professionals with a disability.

Donelly, Michelle; Given, Fiona

2010-01-01

It is unclear whether or not open (competitive) employment programs are meeting the needs of the growing numbers of people with a disability seeking professional employment. To understand and describe the experience of a newly graduated professional (Michael) who was seeking open employment support and to analyze those experiences in relation to principles of effective open employment support. Michael a recently graduated accountant who also has a physical disability. A review of the literature was undertaken to identify recommended principles and practices for the conduct of effective open employment and career development programs. A case study was used to describe Michael's experiences as he sought professional employment. Michael's experiences were analysed in relation to recommended principles and practice. The analysis confirmed that the concerns Michael experienced about the supported employment program compromised the effectiveness of the support he received. Employment services based on models of independent living, disability service standards and remediation are likely to focus on the 'pathology' or performance 'deficits' of the person with a disability. Successful open employment models are more likely to place pre-eminence on the perspective of the person with a disability and effective practices for securing employment.

An analysis of occupational homicides involving workers 19 years old and younger.

PubMed

Janicak, C A

1999-12-01

Studies indicate that persons employed in various retail occupations such as convenience stores and restaurants experience an increased risk for being a victim of an occupational homicide. A large proportion of workers aged 19 and under are employed in these types of occupations. The purpose of this study was to determine if the workers from this age group employed in retail trades have a significantly greater risk for being a victim of a homicide. Data from the Bureau of Labor Statistics' Census of Fatal Occupational Injuries were analyzed in this study. The cases included in this study were victims of an occupational homicide that occurred during the period of 1992 to 1996. Proportionate mortality ratios were used to identify the industries in which workers aged 19 and under were experiencing significantly higher proportion of fatalities. Relative risks were calculated to determine if, based on the number of person-years of exposure, workers aged 19 and under in retail trades were experiencing a significantly greater relative risk for being a victim of an occupational homicide. Results indicate that workers aged 19 and under experience a significantly greater proportion of fatalities due to violence in the retail trade. Workers 19 years and under employed in retail trade occupations do experience a significantly greater proportion of fatalities than their counterparts in other industries. Prevention strategies presented include providing employee training and implementing various security measures.

The contribution of perceptual factors and training on varying audiovisual integration capacity.

PubMed

Wilbiks, Jonathan M P; Dyson, Benjamin J

2018-06-01

The suggestion that the capacity of audiovisual integration has an upper limit of 1 was challenged in 4 experiments using perceptual factors and training to enhance the binding of auditory and visual information. Participants were required to note a number of specific visual dot locations that changed in polarity when a critical auditory stimulus was presented, under relatively fast (200-ms stimulus onset asynchrony [SOA]) and slow (700-ms SOA) rates of presentation. In Experiment 1, transient cross-modal congruency between the brightness of polarity change and pitch of the auditory tone was manipulated. In Experiment 2, sustained chunking was enabled on certain trials by connecting varying dot locations with vertices. In Experiment 3, training was employed to determine if capacity would increase through repeated experience with an intermediate presentation rate (450 ms). Estimates of audiovisual integration capacity (K) were larger than 1 during cross-modal congruency at slow presentation rates (Experiment 1), during perceptual chunking at slow and fast presentation rates (Experiment 2), and, during an intermediate presentation rate posttraining (Experiment 3). Finally, Experiment 4 showed a linear increase in K using SOAs ranging from 100 to 600 ms, suggestive of quantitative rather than qualitative changes in the mechanisms in audiovisual integration as a function of presentation rate. The data compromise the suggestion that the capacity of audiovisual integration is limited to 1 and suggest that the ability to bind sounds to sights is contingent on individual and environmental factors.

1974-01-01

Relativity predicts that the transit time of a signal propagated from the earth to a spacecraft and retransmitted back to earth ought to exhibit an additional, variable time delay. The present work describes some of the analytical techniques employed in experiments using Mariner spacecraft designed to test the accuracy of this prediction. Two types of data are analyzed in these relativity experiments; these include phase-coherent, two-way Doppler shift and round-trip, transit-time measurements. Results of Mariner 6 and 7 relativistic time-delay experiments are in agreement with Einstein's theory of general relativity with an uncertainty of 3%.

Penalized or Protected? Gender and the Consequences of Nonstandard and Mismatched Employment Histories

PubMed Central

Pedulla, David S.

2016-01-01

Millions of workers are employed in positions that deviate from the full-time, standard employment relationship or work in jobs that are mismatched with their skills, education, or experience. Yet, little is known about how employers evaluate workers who have experienced these employment arrangements, limiting our knowledge about how part-time work, temporary agency employment, and skills underutilization affect workers’ labor market opportunities. Drawing on original field and survey experiment data, I examine three questions: (1) What are the consequences of having a nonstandard or mismatched employment history for workers’ labor market opportunities? (2) Are the effects of nonstandard or mismatched employment histories different for men and women? and (3) What are the mechanisms linking nonstandard or mismatched employment histories to labor market outcomes? The field experiment shows that skills underutilization is as scarring for workers as a year of unemployment, but that there are limited penalties for workers with histories of temporary agency employment. Additionally, although men are penalized for part-time employment histories, women face no penalty for part-time work. The survey experiment reveals that employers’ perceptions of workers’ competence and commitment mediate these effects. These findings shed light on the consequences of changing employment relations for the distribution of labor market opportunities in the “new economy.” PMID:27182069

Vocational potential in people with spinal cord injury (SCI) are unrealised with rates of employment substantially lower than in the labour force participation of the general population and the pre-injury employment rates. To understand the experience and pathway of people achieving employment outcome after traumatic spinal cord injury by; classifying participants into employment outcome groups of stable, unstable and without employment; identifying pre and post-injury pathways for participants in each group and, exploring the experiences of people of seeking, gaining and maintaining employment. Thirty-one participants were interviewed. Mixed methods approach including interpretive phenomenological analysis and vocational pathway mapping of quantitative data. The most common pathway identified was from study and work pre-injury to stable employment post-injury. Four super-ordinate themes were identified from the interpretive phenomenological analysis; expectations of work, system impacts, worker identity and social supports. Implications for clinical practice include fostering cultural change, strategies for system navigation, promotion of worker identity and optimal use of social supports. The findings increase insight and understanding of the complex experience of employment after spinal cord injury. There is opportunity to guide experimental research, policy development and education concerning the complexity of the return to work experience and factors that influence pathways.

Dynamic System Simulation of the KRUSTY Experiment

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

Klein, Steven Karl; Kimpland, Robert Herbert

2016-05-09

The proposed KRUSTY experiment is a demonstration of a reactor operating at power. The planned experimental configuration includes a highly enriched uranium (HEU) reflected core, cooled by multiple heat pipes leading to Stirling engines for primary heat rejection. Operating power is expected to be approximately four (4) to five (5) kilowatts with a core temperature above 1,000 K. No data is available on any historical reactor employing HEU metal that operated over the temperature range required for the KRUSTY experiment. Further, no reactor has operated with heat pipes as the primary cooling mechanism. Historic power reactors have employed either naturalmore » or forced convection so data on their operation is not directly applicable to the KRUSTY experiment. The primary purpose of the system model once developed and refined by data from these component experiments, will be used to plan the KRUSTY experiment. This planning will include expected behavior of the reactor from start-up, through various transient conditions where cooling begins to become present and effective, and finally establishment of steady-state. In addition, the model can provide indicators of anticipated off-normal events and appropriate operator response to those conditions. This information can be used to develop specific experiment operating procedures and aids to guide the operators in conduct of the experiment.« less

The experience of attempting to return to work following spinal cord injury: a systematic review of the qualitative literature.

PubMed

Hilton, Gillean; Unsworth, Carolyn; Murphy, Gregory

2018-07-01

This review sought to answer the question "What are the barriers and facilitators influencing people's experience of return to work following spinal cord injury?" Studies that met the selection criteria were identified, presented and critically appraised using National Institute for Health and Care Excellence guidelines. Thematic synthesis was completed with studies possessing strong methodological rigor. Synthesis and interpretation involved three stages; coding of primary data; development of descriptive themes reflective of the primary data; and establishment of analytical themes to answer the review question. Data from nine papers were included in the thematic synthesis. Several descriptive themes and three analytical themes were drawn from the data to answer the research question. Analytical themes included: a matrix of personal and environmental factors exists requiring complex navigation in order to create possibilities and opportunities for postinjury employment; the process of seeking or gaining employment shares a reciprocal relationship with the temporal nature of adjustment to spinal cord injury; and there is an intrinsic need for occupational engagement through paid employment. Returning to or gaining employment after spinal cord injury is a fundamentally difficult experience for people. Multiple strategies are required to support the navigation of the process. There is, however, a need in people with spinal cord injury, to be a worker, and with that comes the inherent benefits of being employed. Implications for rehabilitation Returning to work should be a significant focus of spinal cord injury rehabilitation. Employment is both possible and health promoting following spinal cord injury. Multiple strategies are required to support people to navigate the return to work process. It is important to be cognizant of the individual motivations for being a worker and the complexity of the adjustment process. Spinal cord injury centers can provide a consistent and supportive framework and culture of positivity about employment after spinal cord injury.

1991-01-01

OBJECTIVES--To investigate the expectations and employment experiences of male and female doctors who completed vocational training in East Anglia during 1981-7 and to examine the factors which had influenced those who had changed direction early in their careers. DESIGN--Survey conducted by confidential postal questionnaire. SETTING--Britain. SUBJECTS--281 doctors, 233 (83%) of whom responded. MAIN OUTCOME MEASURES--Ideal choice of work on completion of vocational training; present employment; factors which had restricted present choice of work; factors associated with reported satisfaction with job. RESULTS--77/83 (93%) men and 130/150 (87%) women had hoped to work in general practice (p = 0.75). A smaller proportion of women (71%; 106) than men (89%; 74) were in general practice posts (p less than 0.01); only 6% (nine) of women were on maternity leave or caring for children without paid employment. More women than men were working in medical jobs other than general practice (18% (27) women v 4% (three) men; p less than 0.01). 44/91 (49%) women with children had achieved their employment goals compared with 47/59 (80%) women without children and 55/71 (78%) men with children. 87% (72/83) of men and 65% (98/150) of women had achieved the status of principal (p less than 0.01). 162/193 (84%) doctors who had worked in general practice reported satisfaction with their jobs. Dissatisfaction was linked with doing a job different from that hoped for and with perceiving that the share of practice income did not accurately reflect their share of the practice workload. CONCLUSIONS--Steps need to be taken to retain women in general practice, including a statutory part time pay allowance and incentives for practices to allow flexible working hours for doctors with young children.

Recruiting practices employed by the four clinical centers participating in the Dietary Approaches to Stop Hypertension (DASH)-Sodium trial were examined to assess the most successful method of obtaining participants and to describe pertinent learning experiences gained as a result of the trial. The primary recruitment strategies employed by each center were mass mailing brochures (direct, coupon packs, or other) and mass media (advertisements in newspapers, radio, and television spots). Of 412 randomized participants, 265 (64%) were from mass distribution of brochures, 62 (15%) mass media, and 85 (21%) were prior study participants, referred by word-of-mouth, or reported coming from screening events and presentations. Although the most successful method of recruitment was mass mailing brochures, three times as many brochures were distributed to obtain similar success as in the initial DASH trial.

The relationship of maternal employment to early adolescent daily experience with and without parents.

Richards, M H; Duckett, E

1994-02-01

This study examines how maternal work may shape pre- and young adolescents' daily life experience. According to the procedures of the Experience Sampling Method (ESM), 295 10-13-year-old children carried electronic pagers for 1 week and completed self-report forms in response to random signals sent every other hour. Their daily experience did not differ by maternal employment status, with the following exceptions: full-time maternal employment was associated with more time doing homework with mothers and less time in general leisure, while part-time employment was associated with more time doing sports with parents. Relative to those with nonemployed mothers, youth with part-time employed mothers reported more positive daily moods and higher self-esteem, while youth reported time with full-time employed mothers to be the friendliest. While children with employed mothers spent no less time with family, parents, friends, in class or alone, they spent more time alone with fathers.

Assessing the Role of Anhydrite in the KT Mass Extinction: Hints from Shock-loading Experiments

NASA Technical Reports Server (NTRS)

Skala, R.; Lnagenhorst, F.; Hoerz, F.

2004-01-01

Various killing mechanisms have been suggested to contribute to the mass extinctions at the KT boundary, including severe, global deterioration of the atmosphere and hydrosphere due to SO(x) released from heavily shocked, sulfate-bearing target rocks. The devolatilization of anhydrite is predominantly inferred from thermodynamic considerations and lacks experimental confirmation. To date, the experimentally determined shock behavior of anhydrite is limited to solid-state effects employing X-ray diffraction methods. The present report employs additional methods to characterize experimentally shocked anhydrite.

Good job, bad job: The employment experiences of women in recovery from substance abuse.

Sinakhone, Joyce K; Hunter, Bronwyn A; Jason, Leonard A

2017-01-01

Women in metropolitan areas have lower employment participation and employment rates than men. Although women face multiple challenges in the labor market, those who have a history of substance use and are abstinent may have a greater disadvantage in obtaining viable employment opportunities due to factors associated with substance use. No research to date has examined employment experiences among women in recovery from substance use. This study examined employment characteristics and experiences of women who had a history of substance use and lived in sober-living environments in urban areas. Data were collected through telephone interviews to sober living homes that were located in 20 urban areas. Themes identified through thematic analysis included employment challenges, the importance of work to substance abuse recovery, job satisfaction, employment aspirations, and employment support in the sober living home. Employment is important to women in substance abuse recovery, not only as a means for financial support, but also as a life priority. The results highlight how employer scheduling practices, low-level positions, and lack of employment supports impact recovery. Findings provide insight into the need for employment support services, including employer education and flexible policies for women in recovery.

Risky business: Lived experience mental health practice, nurses as potential allies.

PubMed

Byrne, Louise; Happell, Brenda; Reid-Searl, Kerry

2017-06-01

Mental health policy includes a clear expectation that consumers will participate in all aspects of the design and delivery of mental health services. This edict has led to employment roles for people with lived experience of significant mental health challenges and service use. Despite the proliferation of these roles, research into factors impacting their success or otherwise is limited. This paper presents findings from a grounded theory study investigating the experiences of Lived Experience Practitioners in the context of their employment. In-depth interviews were conducted with 13 Lived Experience Practitioners. Risk was identified as a core category, and included sub-categories: vulnerability, 'out and proud', fear to disclose, and self-care. Essentially participants described the unique vulnerabilities of their mental health challenges being known, and while there were many positives about disclosing there was also apprehension about personal information being so publically known. Self-care techniques were important mediators against these identified risks. The success of lived experience roles requires support and nurses can play an important role, given the size of the nursing workforce in mental health, the close relationships nurses enjoy with consumers and the contribution they have made to the development of lived experience roles within academia. © 2016 Australian College of Mental Health Nurses Inc.

Microstructural changes in a cementitious membrane due to the application of a DC electric field.

Covelo, Alba; Diaz, Belen; Freire, Lorena; Novoa, X Ramon; Perez, M Consuelo

2008-07-01

The use of electromigration techniques to accelerate chloride ions motion is commonly employed to characterise the permeability of cementitious samples to chlorides, a relevant parameter in reinforced concrete corrosion. This paper is devoted to the study of microstructure's changes occurring in mortar samples when submitted to natural diffusion and migration experiments. The application of an electric field reduces testing time in about one order of magnitude with respect to natural diffusion experiments. Nevertheless, the final sample's microstructure differs in both tests. Impedance Spectroscopy is employed for real time monitoring of microstructural changes. During migration experiments the global impedance undergoes important increase in shorter period of time compared to natural diffusion tests. So, the forced motion of ions through the concrete membrane induces significant variations in the porous structure, as confirmed by Mercury Intrusion Porosimetry. After migration experiments, an important increase in the capillary pore size (10-100 nm) was detected. Conversely, no relevant variations are found after natural diffusion tests. Results presented in this work cast doubt on the significance of diffusion coefficient values obtained under accelerated conditions.

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

2016-01-01

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

THz pulse doubler at FLASH: double pulses for pump–probe experiments at X-ray FELs

2018-01-01

FLASH, the X-ray free-electron laser in Hamburg, Germany, employs a narrowband high-field accelerator THz source for unique THz pump X-ray probe experiments. However, the large difference in optical paths of the THz and X-ray beamlines prevents utilization of the machine’s full potential (e.g. extreme pulse energies in the soft X-ray range). To solve this issue, lasing of double electron bunches, separated by 28 periods of the driving radiofrequency (at 1.3 GHz), timed for the temporal overlap of THz and X-ray pulses at the experimental station has been employed. In order to optimize conditions for a typical THz pump X-ray probe experiment, X-ray lasing of the first bunch to one-sixth of that of the second has been suppressed. Finally, synchronization of THz radiation pulses was measured to be ∼20 fs (r.m.s.), and a solution for monitoring the arrival time for achieving higher temporal resolution is presented.

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

2016-12-01

Using Einstein-Podolsky-Rosen-Bohm experiments as an example, we demonstrate that the combination of a digital computer and algorithms, as a metaphor for a perfect laboratory experiment, provides solutions to problems of the foundations of physics. Employing discrete-event simulation, we present a counterexample to John Bell's remarkable "proof" that any theory of physics, which is both Einstein-local and "realistic" (counterfactually definite), results in a strong upper bound to the correlations that are being measured in Einstein-Podolsky-Rosen-Bohm experiments. Our counterexample, which is free of the so-called detection-, coincidence-, memory-, and contextuality loophole, violates this upper bound and fully agrees with the predictions of quantum theory for Einstein-Podolsky-Rosen-Bohm experiments.

Determining the wavelength spectrum of neutrons on the NG6 beam line at NCNR

NASA Astrophysics Data System (ADS)

Ivanov, Juliet

2016-09-01

Historically, in-beam experiments and bottle experiments have been performed to determine the lifetime of a free neutron. However, these two different experimental techniques have provided conflicting results. It is crucial to precisely and accurately elucidate the neutron lifetime for Big Bang Nucleosynthesis calculations and to investigate physics beyond the Standard Model. Therefore, we aimed to understand and minimize systematic errors present in the neutron beam experiment at the NIST Center for Neutron Research (NCNR). In order to reduce the uncertainty related to wavelength dependent corrections present in previous beam experiments, the wavelength spectrum of the NCNR reactor cold neutron beam must be known. We utilized a beam chopper and lithium detector to characterize the wavelength spectrum on the NG6 beam line at the NCNR. The experimental design and techniques employed will be discussed, and our results will be presented. Future plans to utilize our findings to improve the neutron lifetime measurement at NCNR will also be described.

Disturbed Experience of Time in Depression—Evidence from Content Analysis

2018-01-01

Disturbances in the experience of time have been a commonly reported feature of depressive disorders since the beginning of modern psychiatry and psychological research. However, qualitative research approaches to investigate the phenomenon are rarely used. We employed content analysis to investigate disturbances of time experience in Major Depressive Disorder. Our analysis from 25 participants showed that individuals with Major Depressive Disorder subjectively seem to have lost the ability to influence or change the present, resulting in an impersonal and blocked future. The present is rendered meaningless, the past unchangeably negative, and the passage of time turned into a dragging, inexorable, and viscous continuance. The overall,—possibly intersubjective—concept of time experience, remains largely intact, causing or adding to depressive mood and suffering. We elaborate on how these findings reflect previous theories on the experience of time in depression. This study might encourage future inquiries into both the phenomenal and neuroscientific foundation of time experience under psychopathological conditions. PMID:29515385

2013-05-01

This paper explores Canadian engineering employers' perceptions of and experiences with internationally educated engineers (recent immigrants to Canada) employed in their organisations for varying lengths of time. Qualitative data were collected from employers using focus group methodology. Findings reflected employers' observations of culturally different behaviours and characteristics in their internationally educated employees, employers' reactions to cultural differences ranging from negative attributions to tolerance, and the implementation of largely ad hoc intra-organisational strategies for managing cultural differences in employer-employee relationships. Findings exposed the lack of corporate intercultural competency in the Canadian engineering profession. Equity and gatekeeping implications are discussed.

To explore strategies to build employer capacity to support people with DD in meaningful employment from perspective of employment support workers. A grounded theory study was conducted with 34 employment support individuals. A theoretical sampling approach was used to identify and recruit participants from multiple sites in Ontario and Alberta. Three main themes, with seven sub-themes, emerged: (1) experiences of supporting employment finding for people with DD, (2) institutional influences on employee experiences, and (3) attitudes, assumptions and stigma. Several recommendations related to building employer capacity were offered. Our findings provide insight on specific elements and strategies that can support building employer capacity for persons with DD.

Creating Constructive Dialogues Around Climate Change

Kiehl, J. T.

2014-12-01

Presenting scientific facts to the general public often creates strong emotional responses in listeners. This is especially the case around issues like climate change, in which strong resistance can arise in individuals and groups. This is an inherent psychological characteristic when conveying disturbing information to people. In this presentation, I will describe personal experiences of presenting climate change science in various public forums. In particular, I will describe two experiences: one in which I was able to effectively work with the emotional reactions to the scientific information and another in which the resistance was difficult to resolve within the group. Based on these experiences and others, I describe an innovative four-stage process for working with situations in which there is strong resistance to the science of climate change (or other challenging scientific issues). I conclude by discussing how this approach can be employed and potential pitfalls with such an approach.

The results revealed that there are statistically significant relationship exist between the chemical oxygen demand index and the location on-sites.

TPACK Development in Science Teacher Preparation: A Case Study in Queensland, Australia

NASA Astrophysics Data System (ADS)

Sickel, Jamie L.

This study sought to identify key experiences that impact the development of technological pedagogical content knowledge (TPACK) of preservice secondary sciences teachers at a medium-sized university in Queensland, Australia. TPACK is a conceptual framework of a body of knowledge that teachers draw upon to influence practice; it is a dynamic and emergent form of knowledge that informs the employment of technology for teaching specific subject matter. This study employed an embedded case study approach, including delivery of a TPACK survey instrument and analysis of participant interviews, to identify the context-specific experiences that promote the development of TPACK among twelve preservice secondary science teachers. The research addresses a specific need cited in the literature, identifying TPACK impact factors, and provides a novel way to visualize TPACK development through contextual experiences. A novel approach to visually representing context-specific experiences and their influence on teacher knowledge, self-efficacy, values and beliefs was employed. Three major findings are presented below: 1) the majority of preservice secondary science teachers were unable to define the constructs of learning and science; 2) a focus on motivation and interest paired with a disconnect between expressed and enacted pedagogical orientation lead to teacher-centered instruction augmented with superficial tactics aimed at generating interest; and 3) difficulty in integrating knowledge bases yielded lower TPACK self-efficacy, which has detrimental impacts on the instruction planned by pre-service teachers for their students. Findings are directly aligned with participants' prior experience, compared to the relevant literature, and utilized to identify implications for teacher preparation as well as recommendations for future research.

An optical communications experiment between a deep space vehicle and an earth terminal is under consideration for later in this decade. The experimental link would be incoherent (direct detection) and would employ two-way cooperative pointing. The deep space optical transceiver would ride piggyback on a spacecraft with an independent scientific objective. Thus, this optical transceiver is being designed for minimum spacecraft impact - specifically, low mass and low power. The choices of laser transmitter, coding/modulation scheme, and pointing mechanization are discussed. A representative telemetry link budget is presented.

Consumer-directed health plans: enrollee views, early employer experience.

PubMed

Frates, Janice; Severoni, Ellen

2005-06-01

Consumer-directed health plans (CDHPs) are a new health insurance product that is of growing interest to employers who are struggling to cope with rising health insurance premium costs and to consumers who are desiring more choice and engagement in their health care. This paper presents the results of a study of California consumer awareness of, and attitudes toward, CDHPs in the context of several national surveys and the experiences of some early-adopting employers. California Health Decisions conducted a telephone survey of 800 insured adult California residents in November 2002. Few respondents had heard of CDHPs. They appealed more to younger, single, less educated, and healthier respondents and those who did not understand them well. The most attractive CDHP features were greater provider choice and health savings accounts' portability and flexibility. Concerns centered on personal financial exposure. While CDHPs' commercial market penetration is increasing, their greatest potential future contributions might be to reduce the number of uninsured Americans by offering an affordable health insurance product and to fund additional health services for retirees. As CDHPs further evolve, more consumer involvement in their refinement, implementation, and evaluation is essential.

Undergraduate nursing assistant employment in aged care has benefits for new graduates.

2018-04-20

To determine how undergraduate assistant in nursing employment in aged care helps to prepare new graduates for clinical work as a registered nurse. The amount and quality of clinical experience afforded by university programs has been the subject of constant debate in the nursing profession. New graduate nurses are often deemed inadequately prepared for clinical practice and so many nursing students seek employment as assistants in nursing whilst studying to increase their clinical experience. This paper presents the first phase of a larger mixed-methods study to explore whether undergraduate assistant in nursing employment in aged care prepares new graduate nurses for the clinical work environment. The first phase involved the collection of quantitative data from a modified Preparation for Clinical Practice survey, which contained 50-scaled items relating to nursing practice. Ethics approval was obtained prior to commencing data collection. New graduate nurses who were previously employed as assistants in nursing in aged care and had at least 3 months' experience as a registered nurse, were invited to complete the survey. Social media and professional networks were used to distribute the survey between March 2015 and May 2016 and again in January 2017 - February 2017. Purposeful and snowballing sampling methods using social media and nursing networks were used to collect survey responses. Data were analysed using principal components analysis. 110 completed surveys were returned. Principal components analysis revealed four underlying constructs (components) of undergraduate assistant in nursing employment in aged care. These were emotional literacy (component 1), clinical skills (component 2), managing complex patient care (component 3) and health promotion (component 4). The 4 extracted components reflect the development of core nursing skills that transcend that of technical skills and includes the ability to situate oneself as a nurse in the care of an individual and in a healthcare team.

Moving beyond the illness: factors contributing to gaining and maintaining employment.

PubMed

Cunningham, K; Wolbert, R; Brockmeier, M B

2000-08-01

The work presented here, exploratory in nature, uses a comparative and qualitative approach to understand the factors associated with the ability of individuals with severe and persistent mental illness to successfully gain and maintain employment. Based on open-ended interviews with individuals in an Assertive Community Treatment (ACT) program, we compare the experiences of those who have been successful gaining and maintaining employment, with those who have been successful gaining but not maintaining work, and those who have been unsuccessful gaining employment. The three groups seemed to differ in three significant ways: (1) in the ways the individuals talked about their illness, (2) in the ways the individuals talked about work, and (3) in the strategies they described for coping with bad days. In each of these areas individuals' awareness of and attitude toward their illness was significant. The findings have clear implications for agencies working to help people with severe and persistent mental illness obtain and maintain employment.

Wind-tunnel based definition of the AFE aerothermodynamic environment. [Aeroassist Flight Experiment

NASA Technical Reports Server (NTRS)

Miller, Charles G.; Wells, W. L.

1992-01-01

The Aeroassist Flight Experiment (AFE), scheduled to be performed in 1994, will serve as a precursor for aeroassisted space transfer vehicles (ASTV's) and is representative of entry concepts being considered for missions to Mars. Rationale for the AFE is reviewed briefly as are the various experiments carried aboard the vehicle. The approach used to determine hypersonic aerodynamic and aerothermodynamic characteristics over a wide range of simulation parameters in ground-based facilities is presented. Facilities, instrumentation and test procedures employed in the establishment of the data base are discussed. Measurements illustrating the effects of hypersonic simulation parameters, particularly normal-shock density ratio (an important parameter for hypersonic blunt bodies), and attitude on aerodynamic and aerothermodynamic characteristics are presented, and predictions from computational fluid dynamic (CFD) computer codes are compared with measurement.

Input Forces Estimation for Nonlinear Systems by Applying a Square-Root Cubature Kalman Filter.

PubMed

Song, Xuegang; Zhang, Yuexin; Liang, Dakai

2017-10-10

This work presents a novel inverse algorithm to estimate time-varying input forces in nonlinear beam systems. With the system parameters determined, the input forces can be estimated in real-time from dynamic responses, which can be used for structural health monitoring. In the process of input forces estimation, the Runge-Kutta fourth-order algorithm was employed to discretize the state equations; a square-root cubature Kalman filter (SRCKF) was employed to suppress white noise; the residual innovation sequences, a priori state estimate, gain matrix, and innovation covariance generated by SRCKF were employed to estimate the magnitude and location of input forces by using a nonlinear estimator. The nonlinear estimator was based on the least squares method. Numerical simulations of a large deflection beam and an experiment of a linear beam constrained by a nonlinear spring were employed. The results demonstrated accuracy of the nonlinear algorithm.

Hierarchical Rhetorical Sentence Categorization for Scientific Papers

Rachman, G. H.; Khodra, M. L.; Widyantoro, D. H.

2018-03-01

Important information in scientific papers can be composed of rhetorical sentences that is structured from certain categories. To get this information, text categorization should be conducted. Actually, some works in this task have been completed by employing word frequency, semantic similarity words, hierarchical classification, and the others. Therefore, this paper aims to present the rhetorical sentence categorization from scientific paper by employing TF-IDF and Word2Vec to capture word frequency and semantic similarity words and employing hierarchical classification. Every experiment is tested in two classifiers, namely Naïve Bayes and SVM Linear. This paper shows that hierarchical classifier is better than flat classifier employing either TF-IDF or Word2Vec, although it increases only almost 2% from 27.82% when using flat classifier until 29.61% when using hierarchical classifier. It shows also different learning model for child-category can be built by hierarchical classifier.

PubMed

Punch, Renée

2016-01-01

In an integrative review of the literature covering the period 2004-2016, the author presents a current picture of the situation of people who are deaf or hard of hearing (DHH) relative to employment and careers-particularly the barriers, facilitators, and stress levels experienced by working DHH adults. First, an overview is provided of findings from recent reports on employment outcomes for people who are DHH. Second, the author reviews the literature on employment and workplace barriers, facilitators, and accommodations for people who are DHH, and relates findings about DHH people's workplace-related stress and fatigue levels and the associated issues of job demand, job control, and social support in the workplace. The article concludes with a discussion of the implications of these findings, in particular the ways in which barriers to full participation of DHH people in the labor market can be addressed.

“They See Us As Machines:” The Experience of Recent Immigrant Women in the Low Wage Informal Labor Sector

2015-01-01

This study explores the organization of work and occupational health risk as elicited from recently immigrated women (n = 8) who have been in the US for less than three years and employed in informal work sectors such as cleaning and factory work in the greater Boston area in Massachusetts. Additional interviews (n = 8) with Community Key Informants with knowledge of this sector and representatives of temporary employment agencies in the area provides further context to the interviews conducted with recent immigrant women. These results were also compared with our immigrant occupational health survey, a large project that spawned this study. Responses from the study participants suggest health outcomes consistent with being a day-laborer scholarship, new immigrant women are especially at higher risk within these low wage informal work sectors. A difference in health experiences based on ethnicity and occupation was also observed. Low skilled temporary jobs are fashioned around meeting the job performance expectations of the employer; the worker’s needs are hardly addressed, resulting in low work standards, little worker protection and poor health outcomes. The rising prevalence of non-standard employment or informal labor sector requires that policies or labor market legislation be revised to meet the needs presented by these marginalized workers.

Acceleration of electrons using laser-driven dielectric microstructures is a promising technology for the miniaturization of particle accelerators. In this work, experimental results are presented of relativistic electron acceleration with 690±100 MVm -1 gradient. This is a record-high accelerating gradient for a dielectric microstructure accelerator, nearly doubling the previous record gradient. To reach higher acceleration gradients the present experiment employs 90 fs duration laser pulses.

Disability, employment and stress regarding ability to pay for housing and healthy food.

PubMed

Smith, Diane L

2013-01-01

To determine if disability is a significant factor in increasing the likelihood of experiencing stress regarding the ability to pay for housing and healthy food. 24.6% (n=16206) of 65,960 adults who responded to the social context optional module of 2009-2010 Behavioral Risk Factor Surveillance System identified themselves as having a disability. Adults with disabilities reported that they experienced significantly more stress about having money to pay for housing and healthy food than adults without disabilities. This research was a quantitative study using a publicly available dataset. A series of logistic regressions were performed to determine the extent that disability affected the likelihood of stress about having enough money for housing and healthy food. Employed persons with a disability are 1.6 times and 1.9 times as likely as persons without a disability to experience stress about not having enough money to pay for housing and healthy food, respectively. Persons not employed with a disability are 1.56 times and 1.83 times as likely to experience stress about not having enough money to pay for housing and healthy food, respectively. For persons with a disability, being female, in poor health, without a health plan and having a lower income were also significant. Education and employment were not significant predictors of experiencing stress regarding money for food or housing. Having a disability is more predictive of experiencing stress about having enough money for housing and healthy food than employment, though variables such as low income and having a health plan, dependent on employment are significant. Therefore, strategies and policy recommendations to reduce stress by increasing employment and income for persons with disabilities were presented.

Valuing the human asset - the impact of university placements on academic performance and graduate employment amongst management students

NASA Astrophysics Data System (ADS)

Brooks, R.

2012-05-01

The employment market for graduates is competitive with employers requiring appropriate work experience in addition to academic qualifications. Sandwich courses, where up to a year is spent in industry, provide an opportunity for structured work experience to be gained alongside studying. Benefits of placements include improved academic performance and the development of transferable skills to increase employability. This paper evaluates the impact of placements on academic performance and graduate employment among management students. Analysing performance data and graduate destinations data, results indicate that management students completing a placement are more likely to perform better academically with improvements in their personal grades between year 2 and the final year. Additionally, a qualitative themed analysis of student experiences indicates placement students feel more confident in engaging with the graduate recruitment process, with a better understanding of their personal skills and an ability to articulate their experience in relation to the workplace.

Disease severity, self-reported experience of workplace discrimination and employment loss during the course of chronic HIV disease: differences according to gender and education.

PubMed

Dray-Spira, R; Gueguen, A; Lert, F

2008-02-01

Evidence for the existence of a harmful effect of chronic disease on employment status has been provided. Although this effect of chronic illness on employment has been reported to be higher among the groups with the lowest position on the labour market, the mechanisms of such inequalities are poorly understood. The present study aimed at investigating social inequalities in the chances of maintaining employment during the course of HIV infection and at examining the correlates of such inequalities. The authors used data from a national representative sample of people living with HIV in France (ANRS-EN12-VESPA survey). Retrospective information on social trajectory and disease characteristics from the time of HIV diagnosis was available. The risk of employment loss associated with indicators of disease severity and HIV-related workplace discrimination was computed over time since HIV diagnosis according to sociodemographic and occupational factors, using Cox proportional hazards models. Among the 478 working-age participants diagnosed as being HIV-infected in the era of multitherapies and employed at the time of HIV diagnosis, 149 experienced employment loss. After adjusting for sociodemographic and occupational factors, disease severity and self-reported HIV-related discrimination at work were significantly associated with the risk of employment loss in a socially-differentiated manner: advancement in HIV disease was associated with an increased risk of employment loss among women (HR 4.45, 95% CI 2.10 to 9.43) but not among men; self-reported experience of HIV-related discrimination at work was associated with an increased risk of employment loss among individuals with a primary/secondary educational level (HR 8.85, 95% CI 3.68 to 21.30) but not among those more educated. Chronic HIV disease affects the chances of maintaining employment in a socially-differentiated manner, resulting in increasing inequalities regarding workforce participation. Disease severity and workplace HIV-related discrimination, particularly affecting the employment status of the most socioeconomically disadvantaged, may play a major role.

Research studies and popular accounts of parenting have documented the joys and strains of raising children. Much of the literature comparing parents with those without children indicates a happiness advantage for those without children, although recent studies have unpacked this general advantage to reveal differences by the dimension of well-being considered and important features in parents' lives and parenting experiences. We use unique data from the 2010, 2012, and 2013 American Time Use Survey to understand emotions in mothering experiences and how these vary by key demographic factors: employment and partnership status. Assessing mothers' emotions in a broad set of parenting activities while controlling for a rich set of person- and activity-level factors, we find that mothering experiences are generally associated with high levels of emotional well-being, although single parenthood is associated with differences in the emotional valence. Single mothers report less happiness and more sadness, stress, and fatigue in parenting than partnered mothers, and these reports are concentrated among those single mothers who are not employed. Employed single mothers are happier and less sad and stressed when parenting than single mothers who are not employed. Contrary to common assumptions about maternal employment, we find overall few negative associations between employment and mothers' feelings regarding time with children, with the exception that employed mothers report more fatigue in parenting than those who are not employed.

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

Female genital mutilation as sexual disability: perceptions of women and their spouses in Akure, Ondo State, Nigeria.

PubMed

Owojuyigbe, Michael; Bolorunduro, Miracle-Eunice; Busari, Dauda

2017-05-01

Disability encompasses the limitations on an individual's basic physical activities, and the consequent social oppressions such individual faces in society. In this regard, the limitation on the use of some parts of the genitals in a patriarchal system is considered a form of disability. This paper describes the perceptions of and the coping mechanisms employed by affected couples dealing with the consequences of female genital mutilation (FGM) as a form of sexual disability. Cultural Libertarianism was employed as a theoretical framework. The paper presents the results of a descriptive cross-sectional study conducted in Akure, Ondo State, Nigeria, with 10 male and 12 female respondents purposively selected through a snowball sampling for in-depth interviews. The findings present the justifications provided for the practice of FGM, and victims' perceptions of how it affects their sexual relations. Furthermore, it highlights coping strategies employed by affected women and their spouses. The study shows that the disabling consequence of FGM is largely sexual in nature, leading to traumatic experiences and negative beliefs about sex, and requiring a myriad of coping strategies employed by the disabled women, and their spouses, which may have its own implications for marital and sexual bliss.

To investigate the use of community-supported agriculture (CSA) as an employer-based health promotion intervention. Quasi-experimental study using a convenience sample of employees at three employers. Participants and controls from three Minnesota employers completed baseline and follow-up health assessments and surveys about their experiences with CSA. A total of 324 participants purchased a CSA share and were eligible for study inclusion. Study participants were matched by age, sex, employer and occupation to a non-randomized control group of individuals who did not purchase a CSA share but completed health assessments during the same time frame as the study participants. The majority of participants were female, white, middle-aged and highly educated. The most common reason for purchasing a CSA share was a desire for fresh food, and the majority of participants were satisfied with their experience. Participants reported a significant increase in the number of vegetables present in the household and the frequency of family meals. The frequency of eating out decreased significantly, especially at fast-food restaurants. Participants also reported an increase in the amount and variety of produce consumed. However, health assessment data did not show significant changes in dietary intake, health status or BMI. CSA participation was associated with improvement in some aspects of the household environment and dietary behaviours. Further research is needed to determine whether employer-based CSA interventions may also lead to improvements in dietary intake and health.

Breast cancer is the most common tumour in Italy in the female population, counting for about 40000 new cases every year. The psychological aspects of breast mutilation and the social and economic implications are receiving increasing attention. Despite of the diffusion of screening programs to detect pre-clinical breast cancers, 30% of patients still undergo radical interventions. Therefore, many women present serious limitations of their social-life that can lead to severe depression since, in occidental countries, the biological function of the breast is less considered than its primary role of femininity and sexuality. The gold-standard is to conceal oncological radicality and aesthetic preservation. The Authors present their experience analysing the techniques employed.

Dusty (or complex) plasmas in the Earth's middle and upper atmosphere ultimately result in exotic phenomena that are currently forefront research issues in the space science community. This paper presents some of the basic criteria and fundamental physical processes associated with the creation, evolution and dynamics of dusty plasmas in the near-Earth space environment. Recent remote sensing techniques to probe naturally created dusty plasma regions are also discussed. These include ground-based experiments employing high-power radio wave interaction. Some characteristics of the dusty plasmas that are actively produced by space-borne aerosol release experiments are discussed. Basic models that may be used to investigate the characteristics of such dusty plasma regions are presented.

This paper presents an experimental method designed to one-dimensionally shock load and subsequently recover liquid samples. Resultant loading profiles have been interrogated via hydrocode simulation as the nature of the target did not allow for direct application of the diagnostics typically employed in shock physics (e.g., manganin stress gauges or Heterodyne velocimeter (Het-V)). The target setup has been experimentally tested using aluminium flyer plates accelerated by a 50-mm bore single-stage gas-gun reaching projectile impact velocities of up to ~500 ms(-1) (corresponding to peak pressures of up to ca. 4 GPa being experienced by fluid samples). Recovered capsules survived well showing only minor signs of damage. Modelled gauge traces have been validated through the use of a (slightly modified) experiment in which a Het-V facing the rear of the inner capsule was employed. In these tests, good correlation between simulated and experimental traces was observed.

Clark, J. P.; Jones, T. V.; LaGraff, J. E.

2007-01-01

A series of experiments are described which examine the growth of turbulent spots on a flat plate at Reynolds and Mach numbers typical of gas-turbine blading. A short-duration piston tunnel is employed and rapid-response miniature surface-heat-transfer gauges are used to asses the state of the boundary layer. The leading- and trailing-edge velocities of spots are reported for different external pressure gradients and Mach numbers. Also, the lateral spreading angle is determined from the heat-transfer signals which demonstrate dramatically the reduction in spot growth associated with favorable pressure gradients. An associated experiment on the development of turbulent wedges is also reported where liquid-crystal heat-transfer techniques are employed in low-speed wind tunnel to visualize and measure the wedge characteristics. Finally, both liquid crystal techniques and hot-film measurements from flight tests at Mach number of 0.6 are presented.

Own-race faces are recognised more accurately than other-race faces and may even be viewed differently as measured by an eye-tracker (Goldinger, Papesh, & He, 2009). Alternatively, observer race might direct eye-movements (Blais, Jack, Scheepers, Fiset, & Caldara, 2008). Observer differences in eye-movements are likely to be based on experience of the physiognomic characteristics that are differentially discriminating for Black and White faces. Two experiments are reported that employed standard old/new recognition paradigms in which Black and White observers viewed Black and White faces with their eye-movements recorded. Experiment 1 showed that there were observer race differences in terms of the features scanned but observers employed the same strategy across different types of faces. Experiment 2 demonstrated that other-race faces could be recognised more accurately if participants had their first fixation directed to more diagnostic features using fixation crosses. These results are entirely consistent with those presented by Blais et al. (2008) and with the perceptual interpretation that the own-race bias is due to inappropriate attention allocated to the facial features (Hills & Lewis, 2006, 2011). Copyright © 2013 Elsevier B.V.

Lidal, Ingeborg Beate; Huynh, Tuan Khai; Biering-Sørensen, Fin

2007-09-15

To review literature on return to work (RTW) and employment in persons with spinal cord injury (SCI), and present employment rates, factors influencing employment, and interventions aimed at helping people with SCI to obtain and sustain productive work. A systematic review for 2000 - 2006 was carried out in PubMed/Medline, AMED, (ISI) Web of Science, EMBASE, CINAHL, PsycInfo and Sociological abstracts database. The keywords 'spinal cord injuries', 'spinal cord disorder', 'spinal cord lesion' or 'spinal cord disease' were cross-indexed with 'employment', 'return to work', 'occupation' or 'vocational'. Out of approximately 270 hits, 110 references were used, plus 13 more found elsewhere. Among individuals with SCI working at the time of injury 21 - 67% returned to work after injury. RTW was higher in persons injured at a younger age, had less severe injuries and higher functional independence. Employment rate improved with time after SCI. Persons with SCI employed ranged from 11.5% to 74%. Individuals who sustained SCI during childhood or adolescence had higher adult employment rates. Most common reported barriers to employment were problems with transportation, health and physical limitations, lack of work experience, education or training, physical or architectural barriers, discrimination by employers, and loss of benefits. Individuals with SCI discontinue working at younger age. This review confirmed low employment rates after SCI. Future research should explore interventions aimed at helping people with SCI to obtain and sustain productive work.

The angiographic evaluation of previously coiled aneurysms can be difficult yet remains critical for determining re-treatment. The main objective of this study was to determine the inter-rater reliability for both the Raymond Scale and per cent embolization among a group of neurointerventionalists evaluating previously embolized aneurysms. A panel of 15 neurointerventionalists examined 92 distinct cases of immediate post-coil embolization and 1 year post-embolization angiographs. Each case was presented four times throughout the study, along with alterations in demographics in order to evaluate intra-rater reliability. All respondents were asked to provide the per cent embolization (0-100%) and Raymond Scale grade (1-3) for each aneurysm. Inter-rater reliability was evaluated by computing weighted kappa values (for the Raymond Scale) and intraclass correlation coefficients (ICC) for per cent embolization. 10 neurosurgeons and 5 interventional neuroradiologists evaluated 368 simulated cases. The agreement among all readers employing the Raymond Scale was fair (κ=0.35) while concordance in per cent embolization was good (ICC=0.64). Clinicians with fewer than 10 years of experience demonstrated a significantly greater level of agreement than the group with greater than 10 years (κ=0.39 and ICC=0.70 vs κ=0.28 and ICC=0.58). When the same aneurysm was presented multiple times, clinicians demonstrated excellent consistency when assessing per cent embolization (ICC=0.82), but moderate agreement when employing the Raymond classification (κ=0.58). Identifying the per cent embolization in previously coiled aneurysms resulted in good inter- and intra-rater agreement, regardless of years of experience. The strong agreement among providers employing per cent embolization may make it a valuable tool for embolization assessment in this patient population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Systematic review of beliefs, behaviours and influencing factors associated with disclosure of a mental health problem in the workplace

PubMed Central

2012-01-01

Background Stigma and discrimination present an important barrier to finding and keeping work for individuals with a mental health problem. This paper reviews evidence on: 1) employment-related disclosure beliefs and behaviours of people with a mental health problem; 2) factors associated with the disclosure of a mental health problem in the employment setting; 3) whether employers are less likely to hire applicants who disclose a mental health problem; and 4) factors influencing employers' hiring beliefs and behaviours towards job applicants with a mental health problem. Methods A systematic review was conducted for the period 1990-2010, using eight bibliographic databases. Meta-ethnography was used to provide a thematic understanding of the disclosure beliefs and behaviours of individuals with mental health problem. Results The searches yielded 8,971 items which was systematically reduced to 48 included studies. Sixteen qualitative, one mixed methods and seven quantitative studies were located containing evidence on the disclosure beliefs and behaviours of people with a mental health problem, and the factors associated with these beliefs and behaviours. In the meta-ethnography four super-ordinate themes were generated: 1) expectations and experiences of discrimination; 2) other reasons for non-disclosure; 3) reasons for disclosure; and 4) disclosure dimensions. Two qualitative, one mixed methods and 22 quantitative studies provided data to address the remaining two questions on the employers perspective. Conclusions By presenting evidence from the perspective of individuals on both sides of the employment interaction, this review provides integrated perspective on the impact of disclosure of a mental health problem on employment outcomes.

Employees with mental health problems: Survey of U.K. employers' knowledge, attitudes and workplace practices.

Brohan, Elaine; Henderson, Claire; Little, Kirsty; Thornicroft, Graham

2010-01-01

To investigate whether employers who have experience of hiring people with mental health problems differ significantly from those without such experience in terms of knowledge, attitudes and behaviours regarding mental health in the workplace, and the concerns which they report about employing people with mental health problems. We also examine whether non-workplace social contact is associated with the above variables. A telephone survey was conducted with a randomly selected sample of British employers. The sample included a similar number of human resource managers and managers/executive employees in other roles. 502 employers took part. Having employed someone with a mental health problem was associated with closer non-workplace social contact. Those with experience of employing applicants with mental health problems had significant differences in knowledge (regarding the law), and behaviour (having a policy on hiring applicants with disabilities) but not in attitudes. Non-workplace social contact may be useful to consider in understanding hiring practices. The nature of social contact at work and possible lack of impact of this contact on employer attitudes and concerns warrants further study. Greater support is needed for employers to understand the law regarding mental health problems in the workplace.

Dimensional psychotic experiences in adolescence: Evidence from a taxometric study of a community-based sample.

PubMed

Taylor, Mark J; Freeman, Daniel; Ronald, Angelica

2016-07-30

Psychotic experiences of varying severity levels are common in adolescence. It is not known whether beyond a certain severity in the general population, psychotic experiences represent a categorically distinct phenomena to milder psychotic experiences. We employed taxometric analytic procedures to determine whether psychotic experiences in adolescence are taxonic (i.e. categorical) or dimensional. Six different psychotic experiences were assessed in a community sample of approximately 5000 adolescents. Three taxometric procedures were conducted. Across all procedures, there was no evidence of a taxon (i.e. a separate latent population) underlying psychotic experiences in adolescence. Rather, a dimensional structure was supported. The results support the notion that psychotic experiences are continuously distributed throughout the general population, and there is no clear discontinuity between milder and more severe psychotic experiences. Thus, these findings support the use of dimensional approaches to understanding psychotic experiences in etiological studies. In clinical practice, categorical cut-offs are needed: the present findings show that a 'natural' break point is not present for identifying severe psychotic experiences, and it is likely therefore that other criteria (such as general functioning) might better aid decision-making with regards to identifying individuals with severe psychotic experiences in need of care during adolescence.

Well-organised medical records are the prerequisite for achieving a high level of performance in primary healthcare settings. Recording balanced structured and coded data as well as free text can improve both quality and organisation of work in the office. It provides a more substantiated support of financial transactions and accountancy, allows better communication with other facilities and institutions, and is a source of valuable scientific research material. This article is the result of an individual experience gained in general practice use of various programs/systems employed within the family medicine frame, and the frame of evaluation of available and commonly-exploited program solutions. The use of various programs allows for systematic adjustments as to the increasingly complex requirements imposed on electronic medical records (EMRs). The experience of a general practitioner, presented in this paper, confirms the assumption that an adequate program to be employed with EMRs should be developed, provided that family medicine practitioners, that is, the final users, have been involved in each and every stage of its development, adjustment, implementation and evaluation.

Headphone screening to facilitate web-based auditory experiments

PubMed Central

Woods, Kevin J.P.; Siegel, Max; Traer, James; McDermott, Josh H.

2017-01-01

Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants, but sacrifice control over sound presentation, and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining if online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing.

Flow visualization experiments have been successfully employed in reservoir engineering research for many years. They involve 2-D geometries in transparent Hele-Shaw cells and glass micromodels. Although much work has been done on immiscible flows (drainage or imbibition), visualization of steamfloods, which constitute a major part of current EOR methods, has not been attempted to data. In this paper, we present experimental results on steam injection in a transparent, pyrex glass Hele-Shaw cell. Both synthetic (Dutrex 739) and natural heavy oils were used under a variety of conditions, including effects of gravity.

A theoretical method is presented for calculating the flow field about wing-body combinations employing bodies deviating only slightly in shape from a circular cylinder. The method is applied to the calculation of the pressure field acting between a circular cylindrical body and a rectangular wing. The case of zero body angle of attack and variable wing incidence is considered as well as the case of zero wing incidence and variable body angle of attack. An experiment was performed especially for the purpose of checking the calculative examples.

Detecting chameleons through Casimir force measurements

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

Brax, Philippe; Bruck, Carsten van de; Davis, Anne-Christine

2007-12-15

The best laboratory constraints on strongly coupled chameleon fields come not from tests of gravity per se but from precision measurements of the Casimir force. The chameleonic force between two nearby bodies is more akin to a Casimir-like force than a gravitational one: The chameleon force behaves as an inverse power of the distance of separation between the surfaces of two bodies, just as the Casimir force does. Additionally, experimental tests of gravity often employ a thin metallic sheet to shield electrostatic forces; however, this sheet masks any detectable signal due to the presence of a strongly coupled chameleon field.more » As a result of this shielding, experiments that are designed to specifically test the behavior of gravity are often unable to place any constraint on chameleon fields with a strong coupling to matter. Casimir force measurements do not employ a physical electrostatic shield and as such are able to put tighter constraints on the properties of chameleons fields with a strong matter coupling than tests of gravity. Motivated by this, we perform a full investigation on the possibility of testing chameleon models with both present and future Casimir experiments. We find that present-day measurements are not able to detect the chameleon. However, future experiments have a strong possibility of detecting or rule out a whole class of chameleon models.« less

Simulations of the Greenland ice sheet 100 years into the future with the full Stokes model Elmer/Ice

NASA Astrophysics Data System (ADS)

Seddik, H.; Greve, R.; Zwinger, T.; Gillet-Chaulet, F.; Gagliardini, O.

2011-12-01

The full Stokes thermo-mechanically coupled model Elmer/Ice is applied to the Greenland ice sheet. Elmer/Ice employs the finite element method to solve the full Stokes equations, the temperature evolution equation and the evolution equation of the free surface. The general framework of this modeling effort is a contribution to the Sea-level Response to Ice Sheet Evolution (SeaRISE) assessment project, a community-organized effort to estimate the likely range of ice sheet contributions to sea level rise over the next few hundred years (http://tinyurl.com/srise-lanl, http://tinyurl.com/srise-umt). The present geometry (surface and basal topographies) is derived from data where the basal topography was created with the preservation of the troughs at the Jakobshavn Ice Stream, Helheim, Kangerdlussuaq and Petermann glaciers. A mesh of the computational domain is created using an initial footprint which contains elements of 5 km horizontal resolution and to limit the number elements on the footprint while maximizing the spatial resolution, an anisotropic mesh adaptation scheme is employed based on the Hessian matrix of the observed surface velocities. The adaptation is carried out with the tool YAMS and the final footprint is vertically extruded to form a 3D mesh of 320880 elements with 17 equidistant, terrain-following layers. The numerical solution of the Stokes and the heat transfer equations employs direct solvers with stabilization procedures. The boundary conditions are such that the temperature at the surface uses the present-day mean annual air temperature given by a parameterization or directly from the available data, the geothermal heat flux at the bedrock is given by data and the lateral sides are open boundaries. A non-linear Weertman law is used for the basal sliding. Results for the SeaRISE 2011 sensitivity experiments are presented so that six different experiments have been conducted, grouped in two sets. The Set C (three experiments) applies a change to the surface precipitation and temperature and the set S (three experiments) applies an amplification factor to change the basal sliding velocity. The experiments are compared to a constant climate control run beginning at present (epoch 2004-1-1 0:0:0) and running up to 100 years holding the climate constant to its present state. The experiments with the amplification factor (Set S) show high sensitivities. Relative to the control run, the scenario with an amplification factor of 3x applied to the sliding velocity produces a Greenland contribution to sea level rise of ~25 cm. An amplification factor of 2.5x produces a contribution of ~16 cm and an amplification factor 2x produces a contribution of ~9 cm. The experiments with the changes to the surface precipitation and temperature (set C) show a contribution to sea level rise of ~4 cm when a factor 1x is applied to the temperature and precipitation anomalies. A factor 1.5x produces a sea level rise of ~8 cm and a factor 2x produces a sea level rise of ~12 cm.

For several years we have been employing a risk-based decision process to guide development and application of advanced technologies, and for research and technology portfolio planning. The process is supported by custom software, in which visualization plays an important role. During requirements gathering, visualization is used to help scrutinize the status (completeness, extent) of the information. During decision making based on the gathered information, visualization is used to help decisionmakers understand the space of options and their consequences. In this paper we summarize the visualization capabilities that we have employed, indicating when and how they have proven useful.

Nespor, Jerald D.; Hudson, B.; Stegall, R. L.; Freedman, Jerome E.

1994-01-01

Wake vortex experiments were conducted at White Sands Missile Range, NM using the AN/MPS-39 Multiple Object Tracking Radar (MOTR). The purpose of these experiments was twofold. The first objective was to verify that radar returns from wake vortex are observed for some time after the passage of an aircraft. The second objective was to verify that other vortex hazard indicators such as ambient wind speed and direction could also be detected. The present study addresses the Doppler characteristics of wake vortex and clear air returns based upon measurements employing MOTR, a very sensitive C-Band phased array radar. In this regard, the experiment was conducted so that the spectral characteristics could be determined on a dwell to-dwell basis. Results are presented from measurements of the backscattered power (equivalent structure constant), radial velocity and spectral width when the aircraft flies transverse and axial to the radar beam. The statistics of the backscattered power and spectral width for each case are given. In addition, the scan strategy, experimental test procedure and radar parameters are presented.

Women's experiences of developing musculoskeletal diseases: employment challenges and policy recommendations.

PubMed

Crooks, Valorie A

2007-07-30

To answer three specific questions: (i) How do women experience the workplace after the onset of a musculoskeletal disease; (ii) What employment policy and programme suggestions can they offer for ways to better support chronically ill women in their abilities to maintain workforce participation; and (iii) How are these women's employment policy and programme recommendations informed by their own lived experiences and desires? In-depth interviews were conducted with 18 women who had developed musculoskeletal diseases while involved in the labour market. Data were coded and analysed thematically. Participants identified three common workplace barriers experienced and three types of workplace accommodations commonly requested. They offered four specific employment policy and programme recommendations for ways to better support women who develop musculoskeletal diseases in maintaining labour market participation. It is found that their employment policy and programme recommendations are informed by their own experiences in the workplace and desires for being supported in maintaining involvement in paid labour. Creating employment programmes and policies that support chronically ill women in their attempts to remain involved in the workforce based on how much paid labour they are able to perform and where they are best able to work is of the utmost importance.

Direct determination of one-dimensional interphase structures using normalized crystal truncation rod analysis

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

Kawaguchi, Tomoya; Liu, Yihua; Reiter, Anthony

Here, a one-dimensional non-iterative direct method was employed for normalized crystal truncation rod analysis. The non-iterative approach, utilizing the Kramers–Kronig relation, avoids the ambiguities due to an improper initial model or incomplete convergence in the conventional iterative methods. The validity and limitations of the present method are demonstrated through both numerical simulations and experiments with Pt(111) in a 0.1 M CsF aqueous solution. The present method is compared with conventional iterative phase-retrieval methods.

Transitioning From Occupational Therapy Student To Practicing Occupational Therapist: First Year of Employment.

PubMed

McCombie, Randy P; Antanavage, Meredith E

2017-04-01

This research examined the transition from occupational therapy student to practicing occupational therapist over the course of one's first year of professional employment, as recalled by a sample of occupational therapists. Surveys were mailed to 500 occupational therapists randomly selected from membership in the American Occupational Therapy Association resulting in 202 returned surveys. Median year of graduation was 1998, ranging from 1967 to 2014. In general, respondents indicated the transition was positive. Having a mentor was related to high job satisfaction and good clinical fit, while supervising an occupational therapy assistant and low self-confidence were viewed as negative impact factors. Recent graduates presented with lower ratings of a positive transition and higher ratings of likelihood of experiencing burnout and initial job stress than earlier graduates. Recommendations for improving the transition experience are presented.

Investigation of students' experiences of gendered cultures in engineering workplaces

NASA Astrophysics Data System (ADS)

Male, Sally A.; Gardner, Anne; Figueroa, Eugenia; Bennett, Dawn

2018-05-01

Women remain severely under-represented in engineering in Australia as in all Western countries. This limits the pool of talent, standpoints and approaches within the profession. Furthermore, this under-representation equates to restriction of the benefits of being an engineer mainly to men. Gendered workplace experiences have been found to contribute to women leaving the profession. In this study we explore students' experiences of gendered cultures in engineering workplaces, using interviews with a purposive sample of 13 students (4 male) recruited following a previous survey. Although the overall experience of workplace learning is positive for many students, male and female engineering students reported experiences consistent with masculine cultures. Educators and employers must proactively lead improvements to the culture in engineering workplaces, prepare students for gendered workplaces and support students to reflect during and after workplace experiences. The experiences presented here could be adapted to enhance inclusivity training.

2008-04-01

No data exist in the English-language literature about patients with Barlow disease associated to Steinert syndrome and little is known about the employment of hypothermic cardiopulmonary bypass (CPB) and hyperkalemic cardioplegia in these patients. We present our experience with six patients affected by myxomatous degeneration associated to Steinert disease undergoing complex mitral valve repair. In all patients we employed mild hypothermic CPB (31 degrees C) and myocardial protection was achieved, in the entire cohort, by the use of blood hyperkalemic cold cardioplegia. The postoperative course was uneventful in all patients and neither shivering nor generalized muscle contraction were observed. Furthermore, all patients have remained well on an outpatient basis. Hypothermic CPB and hyperkalemic cardioplegia can be safely employed in patients with Steinert syndrome requiring complex cardiac surgery. Further large studies are necessary to confirm our findings.

The Family and Medical Leave Act: implications for occupational and environmental health nursing.

PubMed

Rogers, Bonnie; Franke, Joanne V; Jeras, JoAnn; Gravitte, Joy T; Randolph, Susan A; Ostendorf, Judith S

2009-06-01

The Family and Medical Leave Act (FMLA) was enacted in 1993 to balance the demands of the workplace with the needs of families. Balancing work and family responsibilities will affect most workers as they experience their own serious illness or care for a child or a parent. The FMLA continues to present challenges regarding medical certifications, recordkeeping, intermittent leave management, and lack of understanding by employees and employers about rights and responsibilities under the law. This article discusses the rights and responsibilities of both parties. It also discusses how the occupational and environmental health nurse can bridge the gap between meeting the needs of the employee and those of the employer by serving as educator, advocate, and liaison/collaborator, leading to measurable cost savings for the employer and immeasurable benefits for the employee.

Static shape control for adaptive wings

NASA Astrophysics Data System (ADS)

Austin, Fred; Rossi, Michael J.; van Nostrand, William; Knowles, Gareth; Jameson, Antony

1994-09-01

A theoretical method was developed and experimentally validated, to control the static shape of flexible structures by employing internal translational actuators. A finite element model of the structure, without the actuators present, is employed to obtain the multiple-input, multiple-output control-system gain matrices for actuator-load control as well as actuator-displacement control. The method is applied to the quasistatic problem of maintaining an optimum-wing cross section during various transonic-cruise flight conditions to obtain significant reductions in the shock-induced drag. Only small, potentially achievable, adaptive modifications to the profile are required. The adaptive-wing concept employs actuators as truss elements of active ribs to reshape the wing cross section by deforming the structure. Finite element analyses of an adaptive-rib model verify the controlled-structure theory. Experiments on the model were conducted, and arbitrarily selected deformed shapes were accurately achieved.

To describe interactions between men who have sex with men (MSM) and healthcare workers (HCW) in peri-urban township communities in South Africa. Qualitative study using semistructured in-depth interviews and focus group discussions in the Gauteng province townships of Soweto and Mamelodi. 32 MSM were purposively sampled for in-depth interviews and 15 for focus group discussions. Topics explored included identity, sexuality, community life, use of health services and experiences of stigma and discrimination. MSM felt their options for non-stigmatising sexual healthcare services were limited by homophobic verbal harassment by HCW. Gay-identified men sought out clinics with reputations for employing HCW who respected their privacy and their sexuality and challenged those HCW who mistreated them. Non-gay-identified MSM presented masculine, heterosexual identities when presenting for sexual health problems and avoided discussing their sexuality with HCW. The strategies MSM employ to confront or avoid homophobia from HCW may not be conducive to sexual health promotion in this population. Interventions that increase the capacity of public sector HCW to provide appropriate sexual health services to MSM are urgently needed.

Social Anxiety among Chinese People

Fan, Qianqian; Chang, Weining C.

2015-01-01

The experience of social anxiety has largely been investigated among Western populations; much less is known about social anxiety in other cultures. Unlike the Western culture, the Chinese emphasize interdependence and harmony with social others. In addition, it is unclear if Western constructed instruments adequately capture culturally conditioned conceptualizations and manifestations of social anxiety that might be specific to the Chinese. The present study employed a sequence of qualitative and quantitative approaches to examine the assessment of social anxiety among the Chinese people. Interviews and focus group discussions with Chinese participants revealed that some items containing the experience of social anxiety among the Chinese are not present in existing Western measures. Factor analysis was employed to examine the factor structure of the more comprehensive scale. This approach revealed an “other concerned anxiety” factor that appears to be specific to the Chinese. Subsequent analysis found that the new factor—other concerned anxiety—functioned the same as other social anxiety factors in their association with risk factors of social anxiety, such as attachment, parenting, behavioral inhibition/activation, and attitude toward group. The implications of these findings for a more culturally sensitive assessment tool of social anxiety among the Chinese were discussed. PMID:26380367

Individual differences in working memory capacity predict learned control over attentional capture.

PubMed

Robison, Matthew K; Unsworth, Nash

2017-11-01

Although individual differences in working memory capacity (WMC) typically predict susceptibility to attentional capture in various paradigms (e.g., Stroop, antisaccade, flankers), it sometimes fails to correlate with the magnitude of attentional capture effects in visual search (e.g., Stokes, 2016), which is 1 of the most frequently studied tasks to study capture (Theeuwes, 2010). But some studies have shown that search modes can mitigate the effects of attentional capture (Leber & Egeth, 2006). Therefore, the present study examined whether or not the relationship between WMC and attentional capture changes as a function of the search modes available. In Experiment 1, WMC was unrelated to attentional capture, but only 1 search mode (singleton-detection) could be employed. In Experiment 2, greater WMC predicted smaller attentional capture effects, but only when multiple search modes (feature-search and singleton-detection) could be employed. Importantly this relationship was entirely independent of variation in attention control, which suggests that this effect is driven by WMC-related long-term memory differences (Cosman & Vecera, 2013a, 2013b). The present set of findings help to further our understanding of the nuanced ways in which memory and attention interact. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

2016-06-01

This study examined employer perceptions of employability of job candidates working in a social business for people with mental illnesses. Using an analogue research design, 99 employers participated in a simulated job hiring process, rating 2 applicants on potential to do the job, fit with workplace culture and likelihood of hiring. One job applicant worked in a social business, and the second was either (a) working in a conventional business, (b) with employment lapse attributable to mental health issues, or (c) with an unexplained employment lapse. Paired samples t tests were used to compare ratings. Qualitative data were collected regarding the rationale for rankings and a content analysis was conducted. Employer rankings were significantly higher for the applicant working in a social business compared to either applicant with an employment lapse. Employers rated the candidate working in a conventional business significantly higher compared with the candidate in a social business only on ratings of likelihood to hire. Employers valued the recency of work experience in the social business, citing concerns about risks associated with employment lapses. Their comments suggested a lack of understanding of the nature of social business. Experience in a social business appears to lessen the disadvantage of unemployment in the job hiring process, but does not appear to be ranked on par with experience in the conventional workforce. The social business sector could benefit from considering ways to publically portray these work opportunities to enhance acceptance and inclusion.

Employees with attention-deficit/hyperactivity disorder (ADHD) face various risks in the workplace. Little is known of the specific challenges women with ADHD experience. To explore the experiences of working women with ADHD and learn the strategies and accommodations that facilitate their maintaining employment. Qualitative phenomenological approach was used to echo women's subjective perceptions and experiences representing their daily interactions in their workplace. In-depth interviews were conducted with eleven tertiary-educated employed women (M = 33.5; SD = 6.61 years), diagnosed with ADHD and the transcripts were analyzed by three researchers, using the qualitative phenomenological approach. Most interviewed women with ADHD described interactions with their workplace as confusing, overwhelming, and chaotic. They perceived their ADHD as a significant obstacle to success in employment that also conferred some advantages. Three interview themes are explored here (1) challenges in coping with job demands and the workplace, including the disclosure dilemma; (2) personal coping strategies; (3) useful accommodations. For the women interviewed, employment was important for their self-identity, beyond simply making a living. Their experiences indicate impaired executive functioning and inhibition and sensory sensitivity, consistently with theoretical models for ADHD. They identified gender-specific issues, such as using medication during pregnancy, which led them to seek for non-pharmacological coping mechanisms. They contributed practical knowledge regarding employee-led adaptations and employer-provided workplace accommodations.

Employment status and intimate partner violence among Mexican women.

PubMed

Terrazas-Carrillo, Elizabeth C; McWhirter, Paula T

2015-04-01

Exploring risk factors and profiles of intimate partner violence in other countries provides information about whether existing theories of this phenomenon hold consistent in different cultural settings. This study will present results of a regression analysis involving domestic violence among Mexican women (n = 83,159). Significant predictors of domestic violence among Mexican women included age, number of children in the household, income, education, self-esteem, family history of abuse, and controlling behavior of the husband. Women's employment status was not a significant predictor when all variables were included in the model; however, when controlling behavior of the husband was withdrawn from the model, women's employment status was a significant predictor of domestic violence toward women. Results from this research indicate that spousal controlling behavior may serve as a mediator of the predictive relationship between women's employment status and domestic violence among Mexican women. Findings provide support for continued exploration of the factors that mediate experiences of domestic violence among women worldwide. © The Author(s) 2014.

Sequencing Disadvantage: Barriers to Employment Facing Young Black and White Men with Criminal Records

PubMed Central

PAGER, DEVAH; WESTERN, BRUCE; SUGIE, NAOMI

2013-01-01

In this article, the authors report the results of a large-scale field experiment conducted in New York City investigating the effects of race and a prison record on employment. Teams of black and white men were matched and sent to apply for low-wage jobs throughout the city, presenting equivalent resumés and differing only in their race and criminal background. The authors find a significant negative effect of a criminal record on employment outcomes that appears substantially larger for African Americans. The sequence of interactions preceding hiring decisions suggests that black applicants are less often invited to interview, thereby providing fewer opportunities to establish rapport with the employer. Furthermore, employers’ general reluctance to discuss the criminal record of an applicant appears especially harmful for black ex-offenders. Overall, these results point to the importance of rapport-building for finding work, something that the stigmatizing characteristics of minority and criminal status make more difficult to achieve.

Looking into the crystal ball of our emotional lives: emotion regulation and the overestimation of future guilt and shame.

PubMed

van Dijk, Wilco W; van Dillen, Lotte F; Rotteveel, Mark; Seip, Elise C

2017-04-01

In the present study, we examined the impact of emotion regulation on the intensity bias in guilt and shame. Fifty-two undergraduates either forecasted their emotions and emotion regulation following a guilt- and shame-eliciting situation or reported their actual experienced emotions and employed emotion regulation. Results showed a clear intensity bias, that is, forecasters predicted to experience more guilt and shame than experiencers actually experienced. Furthermore, results showed that forecasters predicted to employ less down-regulating emotion regulation (i.e. less acceptance) and more up-regulating emotion regulation (i.e. more rumination) than experiencers actually employed. Moreover, results showed that the intensity differences between forecasted and experienced guilt and shame could be explained (i.e. were mediated) by the differences between forecasted and actually employed emotion regulation (i.e. acceptance and rumination). These findings provide support for the hypothesis that the intensity bias can-at least in part-be explained by the misprediction of future emotion regulation.

Modulation of dental anxiety--the role of past experiences, psychopathologic traits and individual attachment patterns.

PubMed

Eli, I; Uziel, N; Blumensohn, R; Baht, R

2004-06-12

To evaluate factors affecting modulation of dental anxiety among adults. A total of 183 adult members of a closed communal society (Kibbutz), who have been treated since childhood only by the dentists employed in their community, were investigated concerning their past and present dental anxiety, evaluation of their past and present dentists, psychopathologic symptoms and individual pattern of attachment. The best predictor of subjects' evaluation of their present dental anxiety was the scale of anxiety as recorded by the SCL-90R questionnaire. The best predictors of the decrease in subjects' dental anxiety over time were the evaluation of their past and present dentists and the secure and avoidant patterns of attachment. Patterns of attachment (avoidant and ambivalent) were the best predictors of subjects' evaluation of their present dentist. While psychopathologic traits are involved in subjects' present dental anxiety, pattern of attachment may have a dominant affect as to whether anxiety persists throughout life or can be modulated through a corrective emotional experience.

The successful performance of a model predictive profile controller is demonstrated in simulations and experiments on the TCV tokamak, employing a profile controller test environment. Stable high-performance tokamak operation in hybrid and advanced plasma scenarios requires control over the safety factor profile (q-profile) and kinetic plasma parameters such as the plasma beta. This demands to establish reliable profile control routines in presently operational tokamaks. We present a model predictive profile controller that controls the q-profile and plasma beta using power requests to two clusters of gyrotrons and the plasma current request. The performance of the controller is analyzed in both simulation and TCV L-mode discharges where successful tracking of the estimated inverse q-profile as well as plasma beta is demonstrated under uncertain plasma conditions and the presence of disturbances. The controller exploits the knowledge of the time-varying actuator limits in the actuator input calculation itself such that fast transitions between targets are achieved without overshoot. A software environment is employed to prepare and test this and three other profile controllers in parallel in simulations and experiments on TCV. This set of tools includes the rapid plasma transport simulator RAPTOR and various algorithms to reconstruct the plasma equilibrium and plasma profiles by merging the available measurements with model-based predictions. In this work the estimated q-profile is merely based on RAPTOR model predictions due to the absence of internal current density measurements in TCV. These results encourage to further exploit model predictive profile control in experiments on TCV and other (future) tokamaks.

Contextual influences on implicit evaluation: a test of additive versus contrastive effects of evaluative context stimuli in affective priming.

2005-09-01

Drawing on two alternative accounts of the affective priming effect (spreading activation vs. response interference), the present research investigated the underlying processes of how evaluative context stimuli influence implicit evaluations in the affective priming task. Employing two sequentially presented prime stimuli (rather than a single prime), two experiments showed that affective priming effects elicited by a given prime stimulus were more pronounced when this stimulus was preceded by a context prime of the opposite valence than when it was preceded by a context prime of the same valence. This effect consistently emerged for pictures (Experiment 1) and words (Experiment 2) as prime stimuli. These results suggest that the impact of evaluative context stimuli on implicit evaluations is mediated by contrast effects in the attention to evaluative information rather than by additive effects in the activation of evaluative information in associative memory.

Measurements of fill tube perturbations from hydro growth radiography (HGR) experiments on the National Ignition Facility show spoke perturbations in the ablator radiating from the base of the tube. These correspond to the shadow of the 10 μm diameter glass fill tube cast by hot spots at early time. We present 3D integrated HYDRA simulations of these experiments which include the fill tube. Meshing techniques are described which were employed to resolve the fill tube structure and associated perturbations in the simulations. We examine the extent to which the specific illumination geometry necessary to accommodate a backlighter in the HGR experiment contributes to the spoke pattern. Simulations presented include high resolution calculations run on the Trinity machine operated by the Alliance for Computing at Extreme Scale (ACES) partnership. This work was performed under the auspices of the Lawrence Livermore National Security, LLC, (LLNS) under Contract No. DE-AC52-07NA27344.

We present a novel system to calibrate millimeter-wave polarimeters for cosmic microwave background (CMB) polarization measurements. This technique is an extension of the conventional metal mirror rotation approach, however, it employs cryogenically-cooled blackbody absorbers. The primary advantage of this system is that it can generate a slightly polarized signal (∼100 mK) in the laboratory; this is at a similar level to that measured by ground-based CMB polarization experiments observing a ∼10 K sky. It is important to reproduce the observing condition in the laboratory for reliable characterization of polarimeters before deployment. In this paper, we present the design and principle of the system and demonstrate its use with a coherent-type polarimeter used for an actual CMB polarization experiment. This technique can also be applied to incoherent-type polarimeters and it is very promising for the next-generation CMB polarization experiments.

The aims of this paper are to generate estimates of the association between the experience and burden of pain, by severity and frequency, with (1) labor force participation and workforce status in five EU countries (the UK, France, Spain, Germany and Italy) and (2) patterns of absenteeism and presenteeism for the employed workforce. Data are from the internet-based 2008 National Health and Wellness Survey (NHWS). This survey covers both those who report experiencing pain in the last month as well as the no pain population. A series of regression models are developed with the no pain group as the reference category. The impact of pain, categorized by severity and frequency reported, is assessed within a labor supply framework for (1) labor force participation and (2) absenteeism and presenteeism. In the former case both binomial and multinomial logistic models are estimated; in the latter case ordered logit models are estimated. The results demonstrate that, in the context of health status, the experience of frequent severe and moderate pain has a dominant, independent and negative association with labor force participation and employment status as well as absenteeism and presenteeism. The presence of severe daily pain is associated with a 20-point reduction in the probability of being employed full-time; with moderate daily pain associated with a 10-point reduction. The impact of pain is far greater than the potential impact of other health status measures (e.g., chronic comorbidities and BMI). The experience of pain, notably severe and frequent pain, also outstrips the impact of other health status factors in absenteeism and presenteeism. The experience of pain, in particular severe daily pain, has a substantial negative association with labor force participation in these five European countries as well as reported absenteeism and presenteeism. As a measure of health status, it clearly outweighs other health status measures. Whether or not pain is considered as a disease in its own right, the experience of chronic pain, as defined here, presents policy makers with a major challenge. Programs to relieve the burden of pain in the community clearly have the potential for substantial benefits from societal, individual and employer perspectives.

Despite increasing attention to employment within the mental health sector, reports indicate that people with serious mental illness (SMI) continue to experience limited employment success in the province of Ontario, Canada. Research specifies that people with SMI who live in rural places are less likely than those living in urban centers to have access to satisfactory employment services or to become gainfully employed. The objective of this study was to examine access to employment from the perspectives of people with SMI, mental health and vocational service providers, and decision-makers, and to explore whether place influenced their access to work in northeastern Ontario. A qualitative case study using community-based participatory research methods was chosen to examine the experience of access to competitive employment in two northeastern Ontario communities. The cases selected for study were two geographic areas in northeastern Ontario which provided best-practice, mental health services to persons with SMI. Community-based site partners advertised and recruited participants, and a consumer advisory provided input on key stakeholders, questions, findings and the study action plan. The study findings were informed by individual and group interviews conducted with 46 individuals who resided in both rural and urban settings in the case communities, and feedback from 49 participants who attended town hall forums for presentation of study findings and development of an action plan. The qualitative data was supported by a secondary data source reporting on the employment outcomes of 4112 people with SMI who received disability income support and who resided in the case communities. Qualitative data were analyzed inductively, and categories and themes were developed. Findings were member checked with all informants and town hall participants in each case community. This article draws on the findings of a larger study and reports on the influence of place to the low employment success experienced by people with SMI who reside in the case communities; 91.3% of those receiving disability income support are unemployed, and rural residents experience higher levels of unemployment than those in urban places. Place was found to influence access to employment in five ways: by limited access to employment support services in rural places, and to recommended ratios in urban places; by the use of different models and practices that were inconsistent with best practices for people with SMI; by the lack of a plan for the implementation of employment services in the case communities; by limited use of the available, dedicated vocational resources for employment purposes; and by inadequate supports provided to persons with SMI who wish to enter the workforce. The results also underscore how people with SMI continue to be perceived negatively regarding their capacity for employment. Such stereotypical attitudes additionally contributed to employment marginalization of people with SMI from the workforce, especially in rural communities. The study highlights the influence of geography and human resources to the implementation of best practice employment services and supports for persons with SMI. Important policy implications include the need to consider place when implementing evidence-based practices in places where geography, distance and human health resources limit the communities' capacity to successfully do so. The study also underscores the need to build community capacity for supported employment, especially in rural places, in order to improve the participation of people with SMI in employment, and subsequently, to help shift the communities' thinking about their capacity for work.

Previous research has tended to focus on the barriers to employment for people with mental illness and the extra support they may need. This research contributes to the knowledge base pertaining to this population by looking at successful employment relationships in New Zealand. To describe factors enabling and/or sustaining the open employment of people with experience of mental illness. Fifteen pairs of employers and employees were interviewed individually but consecutively (using a semi-structured interview schedule) about their perceptions of the critical factors that enabled and sustained the employee's employment. Employee participants were recruited by advertisement, with employers approached through their employees. Transcripts were analysed using a thematic analysis. Themes raised in the interviews included the meaning of work, disclosure of mental illness, the benefits of working, special arrangements or accommodations, the work environment and key things employers and employees do to sustain successful employment. Four critical success factors were identified relating to disclosure, the employment relationship, freedom from discrimination and workplace flexibility.

The MoEDAL experiment (Monopole and Exotics Detector at the LHC) is designed to directly search for magnetic monopoles and other highly ionising stable or meta-stable particles at the LHC. The MoEDAL detector comprises an array of plastic track detectors and aluminium trapping volumes around the P8 intersection region, opposite from the LHCb detector. TimePix devices are also installed for monitoring of the experiment. As MoEDAL mostly employs passive detectors the software development focusses on particle simulation, rather than digitisation or reconstruction. Here, we present the current status of the MoEDAL simulation software. Specifically, the development of a material description of the detector and simulations of monopole production and propagation at MoEDAL.

Despite the growing importance of cancer and return-to-work issues in occupational rehabilitation literature in the last decade, academic discussion is largely limited to survivors' perspectives and some exploratory studies from the employer side. This paper applies two classic theoretical models-Theory of Planned Behavior and Social Cognitive Theory-and key measures from previous studies to identify explicit relationships that explain employer factors to hire and retain cancer survivors. Data were collected from online surveys with senior management executives and senior human resource specialists from various organizations in Singapore, with a total of 145 responses. The 72-item survey instrument included a series of independent variables: (1) Attitudes toward cancer and cancer survivors; (2) Employers' efficacy; (3) Perceived moral obligation; (4) Employers' experience; (5) Outcome expectations; (6) Employment situation; (7) Social norms; and (8) Incentives, and dependent variables: (a) Employers' intention to hire cancer survivors; and (b) Employers' intention to retain cancer survivors. Regression analyses showed that the top three factors related to employers' intention to retain cancer survivors are perceived moral obligations (β = .39, p < .001), followed by attitudes toward cancer (β = .25, p < .01), and employment situation (β = .17, p < .05). Employers' efficacy was associated with intention to hire (β = .22, p < .05), coupled with attitude toward cancer survivors (β = .22, p < .01). The findings also indicated the important role of existing relationship between an employer and an employee when it comes to retaining cancer survivors and government incentives for hiring cancer survivors in the workforce. The present study provided an avenue to implement the proposed model-a potential study framework for the management of cancer survivors at work. Findings revealed that different messages should be tailored to employers toward hiring and retention issues and provided useful guidelines for employer education materials.

Remaining in paid work is of great importance for cancer survivors, and employers play a crucial role in achieving this. Return to work (RTW) is best seen as a process. This study aims to provide insight into (1) Dutch employers' experiences with RTW of employees with cancer and (2) the employers' needs for support regarding this process. Thirty employer representatives of medium and large for-profit and non-profit organizations were interviewed to investigate their experiences and needs in relation to employees with cancer. A Grounded Theory approach was used. We revealed a trajectory of complex communication and decision-making during different stages, from the moment the employee disclosed that they had been diagnosed to the period after RTW, permanent disability, or the employee's passing away. Employers found this process demanding due to various dilemmas. Dealing with an unfavorable diagnosis and balancing both the employer's and the employee's interests were found to be challenging. Two types of approach to support RTW of employees with cancer were distinguished: (1) a business-oriented approach and (2) a care-oriented approach. Differences in approach were related to differences in organizational structure and employer and employee characteristics. Employers expressed a need for communication skills, information, and decision-making skills to support employees with cancer. The employers interviewed stated that dealing with an employee with cancer is demanding and that the extensive Dutch legislation on RTW did not offer all the support needed. We recommend providing them with easily accessible information on communication and leadership training to better support employees with cancer. • Supporting employers by training communication and decision-making skills and providing information on cancer will contribute to improving RTW support for employees with cancer. • Knowing that the employer will usually be empathic when an employee reveals that they have been diagnosed with cancer, and that the employer also experiences difficulties and dilemmas, might lower the threshold to discuss wishes regarding disclosure, communication, and work issues. • The interests of employer and employee in relation to RTW are interrelated; both have responsibility and a role to play, and are in need of support.

Asthma and the employment experience.

Previous asthma research has had a medical focus, and only one study has investigated the relationship between asthma and employment. This study describes the employment experience in relation to occupational choice and career advancement in 93 sequentially selected adult asthmatics attending a hospital based asthma clinic serving a socially disadvantaged urban population. Repeated hospital admissions and frequent asthma related sick leave from work were identified as contributing factors to employer discrimination, job dismissal, and lack of career advancement. Seventy-seven percent had not informed their employers of their asthma and 32% of those currently employed stated that getting time off work was a problem in relation to Asthma Clinic attendance. Of those not employed, 22.9% were receiving sickness or invalid benefits and 8.3% had lost their jobs because of asthma. This study illustrates how the stigma attached to the diagnosis of asthma in this community may not only impact negatively on employment opportunity, but also on asthma care.

The Value of Science Policy Internships to Interns and Employers

My interns often look at me wide-eyed when I tell them to approach a Member of Congress at a congressional reception and introduce themselves. I understand their shock, as I once had the same experience. This presentation will look at the internship experience from the perspective of the intern and the employer, describing the value of the internship to each. I will detail my experience as an intern in the American Geosciences Institute Government Affairs Program, and my current position as the creator and hiring manager of the American Geophysical Union Public Affairs Department internship. This perspective will be augmented by information from recent AGU Public Affairs interns. Internships equate to experience, one critical and often underdeveloped component of a student or recent graduate's resume. Each of these internships offers the unique opportunity for students and recent graduates of geophysical science programs to immerse themselves in the science policy field, doing work alongside professionals and serving as an important part of their respective work environment. The networking opportunities and skills learned are highly valuable to those building their resumes and trying to break into the field - or simply figuring out what future career path to take. Scientific societies see value in investing in the next generation of scientific leaders and ensuring their perspective includes an understanding of science policy and the societal impacts of science. These internship experiences are often eye-opening and sometimes career-changing.

Chatter detection in milling process based on VMD and energy entropy

Liu, Changfu; Zhu, Lida; Ni, Chenbing

2018-05-01

This paper presents a novel approach to detect the milling chatter based on Variational Mode Decomposition (VMD) and energy entropy. VMD has already been employed in feature extraction from non-stationary signals. The parameters like number of modes (K) and the quadratic penalty (α) need to be selected empirically when raw signal is decomposed by VMD. Aimed at solving the problem how to select K and α, the automatic selection method of VMD's based on kurtosis is proposed in this paper. When chatter occurs in the milling process, energy will be absorbed to chatter frequency bands. To detect the chatter frequency bands automatically, the chatter detection method based on energy entropy is presented. The vibration signal containing chatter frequency is simulated and three groups of experiments which represent three cutting conditions are conducted. To verify the effectiveness of method presented by this paper, chatter feather extraction has been successfully employed on simulation signals and experimental signals. The simulation and experimental results show that the proposed method can effectively detect the chatter.

We present concepts for self-assembly of diffractive optics with potential uses in biosensors and biocomputers. The simplest such optics, diffraction gratings, can potentially be made from chemically-stabilized microtubules migrating on nanopatterned tracks of the motor protein kinesin. We discuss the fabrication challenges involved in patterning sub-micron-scale structures with proteins that must be maintained in aqueous buffers to preserve their activity. A novel strategy is presented that employs dry contact printing onto glass-supported amino-silane monolayers of heterobifunctional crosslinkers, followed by solid-state reactions of these cross-linkers, to graft patterns of reactive groups onto the surface. Successive solution-phase addition of cysteine-mutant proteins andmore » amine-reactive polyethylene glycol allows assembly of features onto the printed patterns. We present data from initial experiments showing successful micro- and nanopatterning of lines of single-cysteine mutants of kinesin interleaved with lines of polyethylene, indicating that this strategy can be employed to arrays of features with resolutions suitable for gratings.« less

Object width modulates object-based attentional selection.

Visual input typically includes a myriad of objects, some of which are selected for further processing. While these objects vary in shape and size, most evidence supporting object-based guidance of attention is drawn from paradigms employing two identical objects. Importantly, object size is a readily perceived stimulus dimension, and whether it modulates the distribution of attention remains an open question. Across four experiments, the size of the objects in the display was manipulated in a modified version of the two-rectangle paradigm. In Experiment 1, two identical parallel rectangles of two sizes (thin or thick) were presented. Experiments 2-4 employed identical trapezoids (each having a thin and thick end), inverted in orientation. In the experiments, one end of an object was cued and participants performed either a T/L discrimination or a simple target-detection task. Combined results show that, in addition to the standard object-based attentional advantage, there was a further attentional benefit for processing information contained in the thick versus thin end of objects. Additionally, eye-tracking measures demonstrated increased saccade precision towards thick object ends, suggesting that Fitts's Law may play a role in object-based attentional shifts. Taken together, these results suggest that object-based attentional selection is modulated by object width.

Impression management serves self-preservation as part of self-experience. It is adapted to a given situation as an expression of understanding of the role it plays in striving for success. Impression management and self-presentation mutually influence each other throughout life. Clichés in the traditional self-presentation of men and woman in their gender-specific domain in occupation belong to the past. In employment, contentment as much as discontent are of prime importance for success or failure in the workplace. As role models attract mainly juveniles, they should be held up to critical scrutiny.

It is imperative to fascinate young children at an early stage in their education for the analytical sciences. The exposure of the public to mass spectrometry presently increases rapidly through the common media. Outreach activities can take advantage of this exposure and employ mass spectrometry as an exquisite example of an analytical science in which children can be fascinated. The presented teaching modules introduce children to mass spectrometry and give them the opportunity to experience a modern research laboratory. The modules are highly adaptable and can be applied to young children from the age of 6 to 14 y. In an interactive tour, the students explore three major scientific concepts related to mass spectrometry; the building blocks of matter, charged particle manipulation by electrostatic fields, and analyte identification by mass analysis. Also, the students carry out a mass spectrometry experiment and learn to interpret the resulting mass spectra. The multistage, inquiry-based tour contains flexible methods, which teach the students current-day research techniques and possible applications to real research topics. Besides the scientific concepts, laboratory safety and hygiene are stressed and the students are enthused for the analytical sciences by participating in "hands-on" work. The presented modules have repeatedly been successfully employed during laboratory open days. They are also found to be extremely suitable for (early) high school science classes during laboratory visit-focused field trips.

To develop a self-report scale of subjective experiences of illness perceived to impact on employment functioning, as an alternative to a diagnostic perspective, for anticipating the vocational assistance needs of people with schizophrenia or schizoaffective disorders. A repeated measures pilot study (n(1) = 26, n(2) = 21) of community residents with schizophrenia identified a set of work-related subjective experiences perceived to impact on employment functioning. Items with the best psychometric properties were applied in a 12 month longitudinal survey of urban residents with schizophrenia or schizoaffective disorder (n(1) = 104; n(2) = 94; n(3) = 94). Construct validity, factor structure, responsiveness, internal consistency, stability, and criterion validity investigations produced favourable results. Work-related subjective experiences provide information about the intersection of the person, the disorder, and expectations of employment functioning, which suggest new opportunities for vocational professionals to explore and discuss individual assistance needs. Further psychometric investigations of test-retest reliability, discriminant and predictive validity, and research applications in supported employment and vocational rehabilitation, are recommended. Subject to adequate psychometric properties, the new measure promises to facilitate exploring: individuals' specific subjective experiences; how each is perceived to contribute to employment restrictions; and the corresponding implications for specialized treatment, vocational interventions and workplace accommodations.

A framework for simulating auditory discrimination experiments, based on an approach from Schädler, Warzybok, Hochmuth, and Kollmeier [(2015). Int. J. Audiol. 54, 100-107] which was originally designed to predict speech recognition thresholds, is extended to also predict psychoacoustic thresholds. The proposed framework is used to assess the suitability of different auditory-inspired feature sets for a range of auditory discrimination experiments that included psychoacoustic as well as speech recognition experiments in noise. The considered experiments were 2 kHz tone-in-broadband-noise simultaneous masking depending on the tone length, spectral masking with simultaneously presented tone signals and narrow-band noise maskers, and German Matrix sentence test reception threshold in stationary and modulated noise. The employed feature sets included spectro-temporal Gabor filter bank features, Mel-frequency cepstral coefficients, logarithmically scaled Mel-spectrograms, and the internal representation of the Perception Model from Dau, Kollmeier, and Kohlrausch [(1997). J. Acoust. Soc. Am. 102(5), 2892-2905]. The proposed framework was successfully employed to simulate all experiments with a common parameter set and obtain objective thresholds with less assumptions compared to traditional modeling approaches. Depending on the feature set, the simulated reference-free thresholds were found to agree with-and hence to predict-empirical data from the literature. Across-frequency processing was found to be crucial to accurately model the lower speech reception threshold in modulated noise conditions than in stationary noise conditions.

The aging of the population and, concomitantly, of the workforce has a number of important implications for governments, businesses, and workers. In this article, we examine the prospects for the employability of older workers as home-based teleworkers. This alternative work could accommodate many of the needs and preferences of older workers and at the same time benefit organizations. However, before telework can be considered a viable work option for many older workers there are a number of issues to consider, including the ability of older workers to adapt to the technological demands that are typically associated with telework jobs and managerial attitudes about older workers and about telework. Through an integrated examination of these and other issues, our goal is to provide a comprehensive understanding of the challenges associated with employing older workers as teleworkers. We also present findings from a questionnaire study that assessed managers’ perceptions of worker attributes desirable for telework and how older workers compare to younger workers on these attributes. The sample included 314 managers with varying degrees of managerial experience from a large variety of companies in the United States. The results presented a mixed picture with respect to the employability of older workers as teleworkers, and strongly suggested that less experienced managers would be more resistant to hiring older people as teleworkers. We conclude with a number of recommendations for improving the prospects for employment of older workers for this type of work arrangement. PMID:20090856

Employing Tropospheric Numerical Weather Prediction Model for High-Precision GNSS Positioning

NASA Astrophysics Data System (ADS)

Alves, Daniele; Gouveia, Tayna; Abreu, Pedro; Magário, Jackes

2014-05-01

In the past few years is increasing the necessity of realizing high accuracy positioning. In this sense, the spatial technologies have being widely used. The GNSS (Global Navigation Satellite System) has revolutionized the geodetic positioning activities. Among the existent methods one can emphasize the Precise Point Positioning (PPP) and network-based positioning. But, to get high accuracy employing these methods, mainly in real time, is indispensable to realize the atmospheric modeling (ionosphere and troposphere) accordingly. Related to troposphere, there are the empirical models (for example Saastamoinen and Hopfield). But when highly accuracy results (error of few centimeters) are desired, maybe these models are not appropriated to the Brazilian reality. In order to minimize this limitation arises the NWP (Numerical Weather Prediction) models. In Brazil the CPTEC/INPE (Center for Weather Prediction and Climate Studies / Brazilian Institute for Spatial Researches) provides a regional NWP model, currently used to produce Zenithal Tropospheric Delay (ZTD) predictions (http://satelite.cptec.inpe.br/zenital/). The actual version, called eta15km model, has a spatial resolution of 15 km and temporal resolution of 3 hours. In this paper the main goal is to accomplish experiments and analysis concerning the use of troposphere NWP model (eta15km model) in PPP and network-based positioning. Concerning PPP it was used data from dozens of stations over the Brazilian territory, including Amazon forest. The results obtained with NWP model were compared with Hopfield one. NWP model presented the best results in all experiments. Related to network-based positioning it was used data from GNSS/SP Network in São Paulo State, Brazil. This network presents the best configuration in the country to realize this kind of positioning. Actually the network is composed by twenty stations (http://www.fct.unesp.br/#!/pesquisa/grupos-de-estudo-e-pesquisa/gege//gnss-sp-network2789/). The results obtained employing NWP model also were compared to Hopfield one, and the results were very interesting. The theoretical concepts, experiments, results and analysis will be presented in this paper.

Myers, T. T.; Johnston, D. E.; Mcruer, D. T.

1986-01-01

The development of flying qualities experiments (OFQ) as a part of the Orbiter Experiments Program (OEX) was continued. The data base was extended to use the ground based cinetheodolite measurements of orbiter approach and landing. Onboard the cinetheodolite data were analyzed from flights STS 2 through 7 to identify the effective augmented vehicle dynamics, the control strategy employed by the pilot during preflare, shallow glide, and final flare segments of the landing, and the key approach and touchdown performance measures. A plan for an OFQ flying qualities data archive and processing is presented.

2012-01-01

Navigation employing low cost MicroElectroMechanical Systems (MEMS) sensors in Unmanned Aerial Vehicles (UAVs) is an uprising challenge. One important part of this navigation is the right estimation of the attitude angles. Most of the existent algorithms handle the sensor readings in a fixed way, leading to large errors in different mission stages like take-off aerobatic maneuvers. This paper presents an adaptive method to estimate these angles using off-the-shelf components. This paper introduces an Attitude Heading Reference System (AHRS) based on the Unscented Kalman Filter (UKF) using the Fast Optimal Attitude Matrix (FOAM) algorithm as the observation model. The performance of the method is assessed through simulations. Moreover, field experiments are presented using a real fixed-wing UAV. The proposed low cost solution, implemented in a microcontroller, shows a satisfactory real time performance. PMID:23012559

2013-11-01

This article presents a formal optimization study of the design of small livestock trailers, within which the majority of animals are transported to market in the UK. The benefits of employing a headboard fairing to reduce aerodynamic drag without compromising the ventilation of the animals' microclimate are investigated using a multi-stage process involving computational fluid dynamics (CFD), optimal Latin hypercube (OLH) design of experiments (DoE) and moving least squares (MLS) metamodels. Fairings are parameterized in terms of three design variables and CFD solutions are obtained at 50 permutations of design variables. Both global and local search methods are employed to locate the global minimum from metamodels of the objective functions and a Pareto front is generated. The importance of carefully selecting an objective function is demonstrated and optimal fairing designs, offering drag reductions in excess of 5% without compromising animal ventilation, are presented.

Unbiased estimation of oceanic mean rainfall from satellite borne radiometer measurements

NASA Technical Reports Server (NTRS)

Mittal, M. C.

1981-01-01

The statistical properties of the radar derived rainfall obtained during the GARP Atlantic Tropical Experiment (GATE) are used to derive quantitative estimates of the spatial and temporal sampling errors associated with estimating rainfall from brightness temperature measurements such as would be obtained from a satelliteborne microwave radiometer employing a practical size antenna aperture. A basis for a method of correcting the so called beam filling problem, i.e., for the effect of nonuniformity of rainfall over the radiometer beamwidth is provided. The method presented employs the statistical properties of the observations themselves without need for physical assumptions beyond those associated with the radiative transfer model. The simulation results presented offer a validation of the estimated accuracy that can be achieved and the graphs included permit evaluation of the effect of the antenna resolution on both the temporal and spatial sampling errors.

2014-10-01

There is limited large-scale empirical research into the working lives of adults who have an autism spectrum disorder with no co-occurring intellectual disability. Drawing on data from a national survey, this report describes the employment activities and experiences of 130 adults with Asperger's Disorder (AD) and high functioning autism (HFA) in Australia. Outcome measures include current occupation; occupational skill level and alignment with educational attainment; type of job contract; hours of work; support received to find work; support received in the workplace; and positive and negative experiences of employment. The findings confirm and expand upon existing evidence that adults with AD and HFA, despite their capacity and willingness to work, face significant disadvantages in the labour market and a lack of understanding and support in employment settings.

This article presents the irregular employment situation of non-European union immigrants in Spanish cities. Foreign labor is remarkable for its heterogeneity in terms of country of origin, demographic characteristics, and the different ways in which immigrants have entered the job market. Legal immigrants tend to concentrate in five different branches of activity, such as domestic service (mostly women), hotel and restaurant industry, agriculture, building and retail trade. Migrants who work in agriculture suffer the worst labor conditions than all other migrants. However, all migrants experience difficulty in obtaining residency and labor permits. Four integration strategies among Moroccan immigrants in Catalonia are discussed and can be viewed as support networks of the immigrants.

We present a study on the single ion dynamics in the molten alkali halide NaBr. Quasielastic neutron scattering was employed to extract the self-diffusion coefficient of the sodium ions at three temperatures. Molecular dynamics simulations using rigid and polarizable ion models have been performed in parallel to extract the sodium and bromide single dynamics and ionic conductivities. Two methods have been employed to derive the ion diffusion, calculating the mean squared displacements and the velocity autocorrelation functions, as well as analysing the increase of the line widths of the self-dynamic structure factors. The sodium diffusion coefficients show a remarkable goodmore » agreement between experiment and simulation utilising the polarisable potential.« less

Statistics for demodulation RFI in inverting operational amplifier circuits

NASA Astrophysics Data System (ADS)

Sutu, Y.-H.; Whalen, J. J.

An investigation was conducted with the objective to determine statistical variations for RFI demodulation responses in operational amplifier (op amp) circuits. Attention is given to the experimental procedures employed, a three-stage op amp LED experiment, NCAP (Nonlinear Circuit Analysis Program) simulations of demodulation RFI in 741 op amps, and a comparison of RFI in four op amp types. Three major recommendations for future investigations are presented on the basis of the obtained results. One is concerned with the conduction of additional measurements of demodulation RFI in inverting amplifiers, while another suggests the employment of an automatic measurement system. It is also proposed to conduct additional NCAP simulations in which parasitic effects are accounted for more thoroughly.

This report provides a summary of the experimental, analytical, and numerical results of the Capillary Flow Experiment (CFE) performed aboard the International Space Station (ISS). The experiments were conducted in space beginning with Increment 9 through Increment 16, beginning August 2004 and ending December 2007. Both primary and extra science experiments were conducted during 19 operations performed by 7 astronauts including: M. Fincke, W. McArthur, J. Williams, S. Williams, M. Lopez-Alegria, C. Anderson, and P. Whitson. CFE consists of 6 approximately 1 to 2 kg handheld experiment units designed to investigate a selection of capillary phenomena of fundamental and applied importance, such as large length scale contact line dynamics (CFE-Contact Line), critical wetting in discontinuous structures (CFE-Vane Gap), and capillary flows and passive phase separations in complex containers (CFE-Interior Corner Flow). Highly quantitative video from the simply performed flight experiments provide data helpful in benchmarking numerical methods, confirming theoretical models, and guiding new model development. In an extensive executive summary, a brief history of the experiment is reviewed before introducing the science investigated. A selection of experimental results and comparisons with both analytic and numerical predictions is given. The subsequent chapters provide additional details of the experimental and analytical methods developed and employed. These include current presentations of the state of the data reduction which we anticipate will continue throughout the year and culminate in several more publications. An extensive appendix is used to provide support material such as an experiment history, dissemination items to date (CFE publication, etc.), detailed design drawings, and crew procedures. Despite the simple nature of the experiments and procedures, many of the experimental results may be practically employed to enhance the design of spacecraft engineering systems involving capillary interface dynamics.

The optical properties of an isolated firefly luciferin anion are investigated by using first-principles calculations, employing the many-body perturbation theory to take into account the excitonic effect. The calculated photoabsorption spectra are compared with the results obtained using the time-dependent density functional theory (TDDFT) employing the localized atomic orbital (AO) basis sets and a recent experiment in vacuum. The present method well reproduces the line shape at the photon energy corresponding to the Rydberg and resonance excitations but overestimates the peak positions by about 0.5 eV. However, the TDDFT-calculated positions of some peaks are closer to those of the experiment.more » We also investigate the basis set dependency in describing the free electron states above vacuum level and the excitons involving the transitions to the free electron states and conclude that AO-only basis sets are inaccurate for free electron states and the use of a plane wave basis set is required.« less

Space storable propellant performance program coaxial injector characterization

Burick, R. J.

1972-01-01

An experimental program was conducted to characterize the circular coaxial injector concept for application with the space-storable gas/liquid propellant combination FLOX(82.6% F2)/CH4(g) at high pressure. The primary goal of the program was to obtain high characteristic velocity efficiency in conjunction with acceptable injector/chamber compatibility. A series of subscale (single element) cold flow and hot fire experiments was employed to establish design criteria for a 3000-lbf (sea level) engine operating at 500 psia. The subscale experiments characterized both high performance core elements and peripheral elements with enhanced injector/chamber compatibility. The full-scale injector which evolved from the study demonstrated a performance level of 99 percent of the theoretical shifting characteristic exhaust velocity with low chamber heat flux levels. A 44-second-duration firing demonstrated the durability of the injector. Parametric data are presented that are applicable for the design of circular, coaxial injectors that operate with injection dynamics (fuel and oxidizer velocity, etc.) similar to those employed in the work reported.

2015-12-01

The collaborative research project (SFB 754) at GEOMAR Helmholtz-Centre for Ocean Research Kiel, Germany addresses among others the decreasing concentrations of oxygen in the oceans. The school outreach component of the SFB 754 a project funded by the German Science Foundation aims to spread the science behind ocean de-oxygenation in secondary schools in Germany. To realise this goal, a series of hands-on experiments have been developed on different topics like gas solubility in water, gas transport in the ocean, oxygen production by phytoplankton, oxygen consumption by bacteria and experiments on nutrient uptake by phytoplankton. The experiments developed are simple, using low cost and reusable materials thus ensuring affordability in schools. For the hands-on session the following experiments will be presented: (1) The effects of temperature, oxygen partial pressure, nature of solute and nature of solvent on the solubility of oxygen in water will be demonstrated using Luer-Lock syringes, (2) Oxygen transport from the ocean surface to the deep will be shown in an experiment using a modification of the "blue-bottle" experiment, and (3) Simulation of ocean circulation employing a 2-dimensional tank. Applications and experiment ideas using immobilised phytoplankton and other procedures suitable for schools for measuring oxygen consumption by bacteria will be introduced in a poster presentation.

Speaker information affects false recognition of unstudied lexical-semantic associates.

Recognition of and memory for a spoken word can be facilitated by a prior presentation of that word spoken by the same talker. However, it is less clear whether this speaker congruency advantage generalizes to facilitate recognition of unheard related words. The present investigation employed a false memory paradigm to examine whether information about a speaker's identity in items heard by listeners could influence the recognition of novel items (critical intruders) phonologically or semantically related to the studied items. In Experiment 1, false recognition of semantically associated critical intruders was sensitive to speaker information, though only when subjects attended to talker identity during encoding. Results from Experiment 2 also provide some evidence that talker information affects the false recognition of critical intruders. Taken together, the present findings indicate that indexical information is able to contact the lexical-semantic network to affect the processing of unheard words.

Despite the emergence of and widespread uptake of a growing range of medical and scientific professions in elite sport, such environs present a volatile professional domain characterized by change and unprecedentedly high turnover of personnel. This study explored sport medicine and science practitioners' experiences of organizational change using a longitudinal design over a 2-year period. Specifically, data were collected in three temporally defined phases via 49 semi-structured interviews with 20 sport medics and scientists employed by three organizations competing in the top tiers of English football and cricket. The findings indicated that change occurred over four distinct stages; anticipation and uncertainty, upheaval and realization, integration and experimentation, normalization and learning. Moreover, these data highlight salient emotional, behavioral, and attitudinal experiences of medics and scientists, the existence of poor employment practices, and direct and indirect implications for on-field performance following organizational change. The findings are discussed in line with advances to extant change theory and applied implications for prospective sport medics and scientists, sport organizations, and professional bodies responsible for the training and development of neophyte practitioners. © 2014 John Wiley & Sons A/S.

Acoustic and perceptual cues for compound-phrasal contrasts in Vietnamese.

PubMed

Nguyen, Anh-Thu T; Ingram, John C L

2007-09-01

This paper reports two series of experiments that examined the phonetic correlates of lexical stress in Vietnamese compounds in comparison to their phrasal constructions. In the first series of experiments, acoustic and perceptual characteristics of Vietnamese compound words and their phrasal counterparts were investigated on five likely acoustic correlates of stress or prominence (f0 range and contour, duration, intensity and spectral slope, vowel reduction), elicited under two distinct speaking conditions: a "normal speaking" condition and a "maximum contrast" condition which encouraged speakers to employ prosodic strategies for disambiguation. The results suggested that Vietnamese lacks phonetic resources for distinguishing compounds from phrases lexically and that native speakers may employ a phrase-level prosodic disambiguation strategy (juncture marking), when required to do so. However, in a second series of experiments, minimal pairs of bisyllabic coordinative compounds with reversible syllable positions were examined for acoustic evidence of asymmetrical prominence relations. Clear evidence of asymmetric prominences in coordinative compounds was found, supporting independent results obtained from an analysis of reduplicative compounds and tone sandhi in Vietnamese [Nguye;n and Ingram, 2006]. A reconciliation of these apparently conflicting findings on word stress in Vietnamese is presented and discussed.

We present a modification of the standard electron transport methodology based on the (non-equilibrium) Green's function formalism to efficiently simulate STM-images. The novel feature of this method is that it employs an effective embedding technique that allows us to extrapolate properties of metal substrates with adsorbed molecules from quantum-chemical cluster calculations. To illustrate the potential of this approach, we present an application to STM-images of C58-dimers immobilized on Au(111)-surfaces that is motivated by recent experiments.

An improved electrochemical cell comprising an additive-modified molten alkali metal electrode-reactant and/or electrolyte is disclosed. Various electrochemical cells employing a molten alkali metal, e.g., sodium, electrode in contact with a cationically conductive ceramic membrane experience a lower resistance and a lower temperature coefficient of resistance whenever small amounts of selenium are present at the interface of the electrolyte and the molten alkali metal. Further, cells having small amounts of selenium present at the electrolyte-molten metal interface exhibit less degradation of the electrolyte under long term cycling conditions.

Breastfeeding and employment: an assessment of employer attitudes.

PubMed

Libbus, M Kay; Bullock, Linda F C

2002-08-01

Both research and anecdotal reports suggest that maternal employment is associated with failure to initiate breastfeeding and early breastfeeding attrition. The objective of this study was to describe the experience with and attitudes toward breastfeeding of a sample of employers in a small Midwestern city in the United States. Based on an analysis of 85 mail-out questionnaires, we found that less than half of the employers had personal experience with breastfeeding. A large percentage of the sample, however, indicated that they would be willing to facilitate women who wished to breastfeed or express milk in the workplace. However, these employers also stated that they saw little value to their business of supporting breastfeeding in the work environment. Thus, enhancement of breastfeeding opportunity in the work environment may come as a result of public and employer education but, more likely, will require some type of directive from official sources.

The influence of employment on subsequent psychiatric hospitalization for people with serious mental illness is unclear. This study examined whether unemployed people with serious mental illness were more or less likely to experience psychiatric hospitalization after gaining employment. A secondary analysis was conducted of data from the Mental Health Treatment Study. Two years of prospective employment and psychiatric hospital outcomes were examined for 2,055 adults with schizophrenia, bipolar disorder, or major depression. The analyses examined associations between employment and psychiatric hospitalization via multilevel regression by using time-lagged modeling. Employment was associated with a lower subsequent three-month risk of psychiatric hospitalization (odds ratio=.65, 95% confidence interval=.50-.84) after the analysis adjusted for baseline characteristics, including previous psychiatric hospitalizations and self-reported physical health. Unemployed outpatients with serious mental illness were less likely to experience psychiatric hospitalization after gaining employment.

In the United States, adults with Autism Spectrum Disorder (ASD) experience high rates of unemployment and underemployment in relation to adults with other disabilities and the general population. Yet there is little research examining their employment experiences and the predictors of employment status. The purpose of this study was to examine the employment characteristics and histories of both employed and unemployed adults with ASD, and the factors that contributed to their employment status. This cross-sectional study used an online survey and the Short Effort Reward Imbalance (ERI) Scale to gather data. Multivariate logistic regression analyses were used to examine predictors of employment status and self-reported health. Of the 254 adults with ASD who participated in this study, 61.42% were employed and 38.58% were unemployed. Over half of the participants reported job imbalance on the Short ERI Scale and the vast majority did not receive any job assistance. Participants who disclosed their ASD diagnosis to their employer were more than three times as likely to be employed than those who did not disclose. Education level was also a significant predictor of employment status. This study suggests disability disclosure and education level are factors that contribute to employment status.

Maladjustment to Academic Life and Employment Anxiety in University Students with Irritable Bowel Syndrome

The present study tested our hypothesis that university students with irritable bowel syndrome (IBS) may experience less satisfactory academic lives than those of students without IBS. We also verified the hypothesis that university students with IBS might have higher employment anxiety than students without IBS might. We conducted a cross-sectional study of 1,686 university students. Presence or absence of IBS was assessed via the Rome III Questionnaire. Two original items were used to evaluate academic life. The prevalence rates of IBS with diarrhea, IBS with constipation, mixed IBS, and unsubtyped IBS in the study population were 5%, 2%, 10%, and 3%, respectively. Regarding academic life, the proportions of participants who experienced maladjustment and employment anxiety were 29% and 50%, respectively. After adjusting for age, sex, and faculty, the odds ratios for maladjustment and employment anxiety were significantly higher in students who screened positively, relative to those who screened negatively, for IBS (OR, 1.62; 95% CI, 1.24–2.21; OR, 2.16; 95% CI, 1.68–2.81, respectively). In conclusion, maladjustment and anxiety over future employment were higher in university students with IBS relative to those without. PMID:26083662

Inpatient mental healthcare continues to be an area of high risk and where patients report negative experiences. To ensure the patient voice is heard, National Health Service (NHS) Trusts are required to collect feedback from patients routinely. We do not know what kinds of feedback are most important or what management processes are needed to translate this into effective action plans. Further, we do not know if this makes any difference to the patients themselves. This study seeks to explore which of the many different approaches to collecting and using patient experience data are the most useful for supporting improvements in inpatient mental healthcare. The overarching aim of the study is to arrive at recommendations for best practice in the collection and use of patient experience data in NHS England adult inpatient mental health settings. We present the protocol for Realist Evaluation of the Use of Patient Experience Data to Improve the Quality of Inpatient Mental Health Care study (EURIPIDES). The study is composed of five work packages (WPs), including a systematic review of patient experiences (WP1); a telephone survey to assist the selection of case sites (WP2); six indepth case studies involving interviews with service users, carers and staff to enable a realist evaluation of the use of patient experience to improve quality in adult inpatient mental health services (WP3); an economic evaluation of patient experience feedback activity (WP5); and a consensus conference (WP4). We discuss the methodological rationale for the five WPs. This study has received approval from West Midlands/South Birmingham NHS Research Ethics Committee. The outcome of the consensus conference meeting (WP4) will form the basis of the outputs to be disseminated to NHS providers. Dissemination will also take place through publications and presentations at relevant conferences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Temporary employment leads to psychological distress and higher mortality, but data on its associations with oral health is limited. We examined whether having the experience of temporary employment was associated with tooth loss among working adults in Japan. We conducted a cross-sectional study from the 2010-2011 Japanese Study on Stratification, Health, Income, and Neighborhood study that analyzed 2652 participants aged 25-50 years (men = 1394; women = 1258). Independent variable was changes in employment status (continuous regular employment and the experience of temporary employment). Dependent variable was self-reported tooth loss (none, 1 tooth, 2 teeth, 3 teeth, 4 teeth, and more than 4 teeth). Covariates were sex, age, years of education, self-rated household economic status in early life at 5 years old, marital status, number of family members in the household, history of diabetes, and body mass index. We conducted a negative binomial regression analysis to estimate prevalence rate ratios (PRRs) and 95% confidence intervals (95%CIs) for tooth loss. We also confirmed the interaction term between changes in employment status and sex. The median age of the participants was 37 years. The percentages of men and women who experienced temporary employment were 14.5% and 61.3%, respectively. Compared with continuous regular employment, the experience of temporary employment was significantly associated with tooth loss in both sexes after adjusting for the covariates (men: PRR = 1.50 [95%CI = 1.13, 2.00]; women: PRR = 1.42 [95%CI = 1.14, 1.76]). The interaction term between employment status and sex was not significant (p = 0.71). Temporary employment is adversely associated with oral health.

Does care matter? Care capital and mothers’ time to paid employment

PubMed Central

Hogan, Dennis

2014-01-01

The aim of this study is to introduce the concept of care capital and provide an example of its application in the context of childcare and maternal employment using the currently most suitable American data. We define care capital as the nexus of available, accessible, and experienced resources for care. The American setting is an ideal context to investigate the linkages between child care capital and maternal employment as the patterns of child care use tend to be more diverse compared to other national contexts. In the presented application of care capital, we examine mothers’ entry to paid employment during the first 36 weeks following a birth, and its association with the experience of non-parental child care use before labour force entry. Using data from the Early Childhood Longitudinal Survey—Birth Cohort (N = 10,400 mothers), results from discrete-time hazard models show that use of non-parental child care prior to employment is independently and positively associated with entry into maternal employment. This finding applies both to first-time mothers (n = 3,800) and to mothers of multiple children (n = 6,600). Although data currently available for investigating child care capital are limited with regard to care availability and access, our results suggests that childcare availability, access, and use, understood as a form of capital alongside economic and human capital, should be considered in future studies of maternal employment.

The aim of this study is to introduce the concept of care capital and provide an example of its application in the context of childcare and maternal employment using the currently most suitable American data. We define care capital as the nexus of available, accessible, and experienced resources for care. The American setting is an ideal context to investigate the linkages between child care capital and maternal employment as the patterns of child care use tend to be more diverse compared to other national contexts. In the presented application of care capital, we examine mothers' entry to paid employment during the first 36 weeks following a birth, and its association with the experience of non-parental child care use before labour force entry. Using data from the Early Childhood Longitudinal Survey-Birth Cohort ( N = 10,400 mothers), results from discrete-time hazard models show that use of non-parental child care prior to employment is independently and positively associated with entry into maternal employment. This finding applies both to first-time mothers ( n = 3,800) and to mothers of multiple children ( n = 6,600). Although data currently available for investigating child care capital are limited with regard to care availability and access, our results suggests that childcare availability, access, and use, understood as a form of capital alongside economic and human capital, should be considered in future studies of maternal employment.

Choice as a dependent measure in autoshaping: sensitivity to frequency and duration of food presentation.

Picker, M; Poling, A

Previous investigations have shown that rate, latency, and percentage of trials with at least one response are somewhat insensitive measures of the strength of autoshaped responding. In the present studies, these measures were contrasted with the allocation of responding during simultaneous choice tests, a measure of response strength frequently used in operant paradigms. In two experiments, nine pigeons were exposed to a forward pairing autoshaping procedure. Training sessions consisted of the successive presentation of three stimuli, each followed by food on either 100%, 50%, or 0% of the trials. Choice testing involved the simultaneous presentation of the three stimuli. In Experiment I, all pigeons consistently directed their initial choice responses and the majority of subsequent responses to the stimulus always followed by food, despite the fact that during training sessions the response rates of most birds were highest in the presence of the stimulus followed by food on 50% of the trials. In Experiment II, rate, latency, and percentage of trials with at least one response did not change appreciably as a function of duration of feeder presentations. However, choice responding was lawfully affected by duration of feeder presentations. These data suggest that choice is perhaps a more sensitive measure of the strength of autoshaped responding than other, more commonly employed, indices. PMID:7097152

Effect of Aperture Field Variability, Flow Rate, and Ionic Strength on Colloid Transport in Single Fractures: Laboratory-Scale Experiments and Numerical Simulation

2007-12-01

A good understanding of the physico-chemical processes (i.e., advection, dispersion, attachment/detachment, straining, sedimentation etc.) governing colloid transport in fractured media is imperative in order to develop appropriate bioremediation and/or bioaugmentation strategies for contaminated fractured aquifers, form management plans for groundwater resources to prevent pathogen contamination, and identify suitable radioactive waste disposal sites. However, research in this field is still in its infancy due to the complex heterogeneous nature of fractured media and the resulting difficulty in characterizing this media. The goal of this research is to investigate the effects of aperture field variability, flow rate and ionic strength on colloid transport processes in well characterized single fractures. A combination of laboratory-scale experiments, numerical simulations, and imaging techniques were employed to achieve this goal. Transparent replicas were cast from natural rock fractures, and a light transmission technique was employed to measure their aperture fields directly. The surface properties of the synthetic fractures were characterized by measuring the zeta-potential under different ionic strengths. A 33 (3 increased to the power of 3) factorial experiment was implemented to investigate the influence of aperture field variability, flow rate, and ionic strength on different colloid transport processes in the laboratory-scale fractures, specifically dispersion and attachment/detachment. A fluorescent stain technique was employed to photograph the colloid transport processes, and an analytical solution to the one-dimensional transport equation was fit to the colloid breakthrough curves to calculate the average transport velocity, dispersion coefficient, and attachment/detachment coefficient. The Reynolds equation was solved to obtain the flow field in the measured aperture fields, and the random walk particle tracking technique was employed to model the colloid transport experiments. The images clearly show the development of preferential pathways for colloid transport in the different aperture fields and under different flow conditions. Additionally, a correlation between colloid deposition and fracture wall topography was identified. This presentation will demonstrate (1) differential transport between colloid and solute in single fractures, and the relationship between differential transport and aperture field statistics; (2) the relationship between the colloid dispersion coefficient and aperture field statistics; and (3) the relationship between attachment/detachment, aperture field statistics, fracture wall topography, flow rate, and ionic strength. In addition, this presentation will provide insight into the application of the random walk particle tracking technique for modeling colloid transport in variable-aperture fractures.

Guzman-Garcia, D.; Rowland, D. E.; Uribe, P.; Nieves-Chinchilla, T.

2012-12-01

Space activities are very expensive and include a high degree of risk. Nowadays, CubeSat missions represent a fast and inexpensive way to conduct scientific space research. These platforms are less expensive to develop and build than conventional satellites. There are ample demonstration that these platforms are well suited for a wide range of science missions in different fields, such as astrobiology, astronomy, atmospheric science, space weather and biology. This paper presents a hybrid "processor in an Field Programmable Gate Array (FPGA)" experiment/spacecraft controller for Cubesat missions. The system has two objectives, first is to obtain a multipurpose and easily customizable system aimed at processing the data from the widest kind of instruments and second, to provide the system with the highest processing capabilities in order to be able to perform complex onboard algorithms. Due to the versatility of the system and its reduced dimensions, it can be employed in different space platforms. The system is envisioned to be employed for the first time as the smart radio receiver for the upcoming NASA FireStation instrument. It is one of four experiments manifested to fly on an experiment pallet the U.S Department of Defense plans to deploy on the International Space Station in 2013. FireStation will continue analyzing the link between the Lightning and the Terrestrial Gamma Rays initiated by the FireFly Cubesat. The system is responsible for the management of a set of small Heliophysics instrumentats, including a photometer, magnetometer, and electric and magnetic field antennas. A description of the system architecture and its main features are presented. The main functional and performance tests during the integration and calibration phase of the instruments are also discussed.

You Don’t See What I See: Individual Differences in the Perception of Meaning from Visual Stimuli

Partos, Timea R.; Cropper, Simon J.; Rawlings, David

2016-01-01

Everyone has their own unique version of the visual world and there has been growing interest in understanding the way that personality shapes one’s perception. Here, we investigated meaningful visual experiences in relation to the personality dimension of schizotypy. In a novel approach to this issue, a non-clinical sample of subjects (total n = 197) were presented with calibrated images of scenes, cartoons and faces of varying visibility embedded in noise; the spatial properties of the images were constructed to mimic the natural statistics of the environment. In two experiments, subjects were required to indicate what they saw in a large number of unique images, both with and without actual meaningful structure. The first experiment employed an open-ended response paradigm and used a variety of different images in noise; the second experiment only presented a series of faces embedded in noise, and required a forced-choice response from the subjects. The results in all conditions indicated that a high positive schizotypy score was associated with an increased tendency to perceive complex meaning in images comprised purely of random visual noise. Individuals high in positive schizotypy seemed to be employing a looser criterion (response bias) to determine what constituted a ‘meaningful’ image, while also being significantly less sensitive at the task than those low in positive schizotypy. Our results suggest that differences in perceptual performance for individuals high in positive schizotypy are not related to increased suggestibility or susceptibility to instruction, as had previously been suggested. Instead, the observed reductions in sensitivity along with increased response bias toward seeing something that is not there, indirectly implicated subtle neurophysiological differences associated with the personality dimension of schizotypy, that are theoretically pertinent to the continuum of schizophrenia and hallucination-proneness.

The lived experience of working as a musician with an injury.

PubMed

Guptill, Christine

2011-01-01

Research and clinical experience have shown that musicians are at risk of acquiring playing-related injuries. This paper explores findings from a qualitative research study examining the lived experience of professional instrumental musicians with playing-related injuries, which has thus far been missing from the performing arts health literature. This study employed a phenomenological methodology influenced by van Manen to examine the lived experiences of professional musicians with playing-related injuries. Ten professional musicians in Ontario, Canada were interviewed about their experiences as musicians with playing-related injuries. Six of the participants later attended a focus group where preliminary findings were presented. The findings demonstrate a need for education about risk and prevention of injuries that could be satisfied by healthcare professionals and music educators. The practice and training of healthcare professionals should include the "tactful" (van Manen) delivery of care for this important and vulnerable population.

The experiences of individuals in middle adulthood with Asperger syndrome have been the subject of little previous research, especially in terms of their experience of support services. In the present research, 11 adults with Asperger syndrome were interviewed. Interpretative phenomenological analysis (IPA) was used to interpret the interviews. Four themes emerged from the analysis: living with Asperger syndrome; employment issues; experiences with mainstream support; and future steps towards supporting adults with Asperger syndrome. The findings highlighted the anxiety, depression, and communication difficulties that people with Asperger syndrome may experience. Much of the available support is perceived as unsuitable for individuals with Asperger syndrome. All participants wanted to remain as independent as possible, and believed an individualized approach to support would be greatly beneficial. Recommendations are made for future practice to help support adults with Asperger syndrome.

Adverse childhood experiences, including abuse, neglect and household instability, affect lifelong health and economic potential. The present study investigates how adverse childhood experiences are associated with food insecurity by exploring caregivers' perceptions of the impact of their childhood adversity on educational attainment, employment and mental health. Semi-structured audio-recorded in-person interviews that included (i) quantitative measures of maternal and child health, adverse childhood experiences (range: 0-10) and food security using the US Household Food Security Survey Module; and (ii) qualitative audio-recorded investigations of experiences with abuse, neglect, violence and hunger over participants' lifetimes. Households in Philadelphia, PA, USA. Thirty-one mothers of children <4 years old who reported low or very low household food security. Twenty-one caregivers (68 %) reported four or more adverse childhood experiences, and this severity was significantly associated with reports of very low food security (Fisher's exact P=0·021). Mothers reporting emotional and physical abuse were more likely to report very low food security (Fisher's exact P=0·032). Qualitatively, participants described the impact of childhood adverse experiences with emotional and physical abuse/neglect, and household substance abuse, on their emotional health, school performance and ability to maintain employment. In turn, these experiences negatively affected their ability to protect their children from food insecurity. The associations between mothers' adverse experiences in childhood and reports of current household food security should inspire researchers, advocates and policy makers to comprehensively address family hardship through greater attention to the emotional health of caregivers. Programmes meant to address nutritional deprivation and financial hardship should include trauma-informed approaches that integrate behavioural interventions.

Gender-based wage differentials among registered dietitians.

Pollard, Prudence; Taylor, Maxine; Daher, Noha

2007-01-01

The debate on compensation equity is broad-based, addressing many organizational, personal, and outcome factors. Central to compensation philosophy is the issue of gender equity. Health care, like many other industries, remains fraught with gender inequity in compensation. This inequity is partially explained by choice of practice area. However, much remains unexplained. Health care is a female-dominated industry with most of the women working in the allied health professions (eg, nurses, dietitians, etc). Registered dietitians (RD) may experience wage discrimination, similar to registered nurses, but prior to the present study, the assumption was not tested. Using data from the first comprehensive study of RD compensation, we examined gender equity in total cash compensation to RDs. Data were collected on total cash compensation, and questions focused on career progression and work outcomes. For purposes of our study, we analyzed data on 5,477 full-time RDs. Ninety-six percent were women, the median age was 43, and median total cash compensation for RDs employed in the position for at least 1 year was $45,500.00. Women earned $45,285.00 and men earned $50,250.00. A median wage gap of $4,965.00 between women and men was observed. Variability in total cash compensation to women was best explained by size of budget, years of experience, work setting, and educational level. Variability for men was explained by size of budget, years of experience, educational level, and employer status. Conclusions suggest that given the wage discrimination that female RDs experience, work organizations should evaluate their pay plans to monitor pay equity. Factors that women can manage to receive compensation that is equal to that of the men include size of budgets they manage, years of experience in the field, employer status, work setting, and educational level attained. Findings are useful for career advisers, human resource specialists, compensation specialists, supervisors, RDs, and compensation researchers.

Chang, Amy L.

2016-01-01

At the American Society for Microbiology (ASM), fellowships are a key means of providing immersive research opportunities for the student sector. To assess the impact of ASM student activities and inform their planning, the Society commissioned a study of two long-standing initiatives in 2015, namely the ASM Undergraduate Research Fellowship (URF), established in 1993, and the ASM Robert D. Watkins Graduate Research Fellowship (Watkins) Program, established in 1980. A mixed-methods approach was used to collect data about the participants’ fellowship experience, track educational and employment status, and determine program impacts from 325 individuals (223 URF and 73 Watkins fellows). Challenges presented by the study include the fact that inherent in fellowships is the provision of financial support that affords participants opportunities that might otherwise be unavailable to them. As a result, participant feelings of indebtedness to the Society may have introduced biased study responses. In addition, some respondents were asked to reflect on experiences from 20 to 30 years ago—a lapse in time that may have challenged their memories. Based on measures such as enrollment in or completion of advanced degree programs, employment in science, and publication and presentation history, project participants show evidence of accomplishment. Participants also reported gains in affective behaviors such as confidence and belonging. PMID:27158299

``How am I going to work?'' Barriers to employment for immigrant Latinos and Latinas living with HIV in Toronto.

For individuals with HIV positive status, multiple barriers exist to accessing and re-entering employment. Studies on employment for people living with HIV lack a detailed consideration of race and ethnicity. This is the first article that focuses on barriers to employment for the HIV positive Latino community in the Canadian context. To document the barriers that a sample of HIV positive Latinos and Latinas encounter in finding and maintaining employment in Toronto. A non-probability sample of immigrant and refugee Latino men and women living with HIV/AIDS in Toronto participated in in-depth interviews concerning their experiences in the labor market, emphasizing the barriers that they have faced in access to employment. Interviews were audio recorded, transcribed and later analysed with NVivo 9. Two sets of barriers emerged from the analysis: structural barriers that immigrants encounter in access to employment, such as language difficulties, lack of Canadian work experience and anti-immigrant feelings and barriers to employment for HIV positive individuals, principally HIV related stigma and health related issues. Due to their intersectional identities as immigrants/refugees and HIV positive individuals, participants face compounded barriers to employment: Language difficulties, lack of migrant status and Canadian work experience, anti-immigrant sentiments in the labor market, ageism, HIV related stigma and side effects of medications among other barriers related with an HIV positive condition. Such barriers locate participants in a marginalized position in Canadian society.

Latent semantic analysis cosines as a cognitive similarity measure: Evidence from priming studies.

PubMed

Günther, Fritz; Dudschig, Carolin; Kaup, Barbara

2016-01-01

In distributional semantics models (DSMs) such as latent semantic analysis (LSA), words are represented as vectors in a high-dimensional vector space. This allows for computing word similarities as the cosine of the angle between two such vectors. In two experiments, we investigated whether LSA cosine similarities predict priming effects, in that higher cosine similarities are associated with shorter reaction times (RTs). Critically, we applied a pseudo-random procedure in generating the item material to ensure that we directly manipulated LSA cosines as an independent variable. We employed two lexical priming experiments with lexical decision tasks (LDTs). In Experiment 1 we presented participants with 200 different prime words, each paired with one unique target. We found a significant effect of cosine similarities on RTs. The same was true for Experiment 2, where we reversed the prime-target order (primes of Experiment 1 were targets in Experiment 2, and vice versa). The results of these experiments confirm that LSA cosine similarities can predict priming effects, supporting the view that they are psychologically relevant. The present study thereby provides evidence for qualifying LSA cosine similarities not only as a linguistic measure, but also as a cognitive similarity measure. However, it is also shown that other DSMs can outperform LSA as a predictor of priming effects.

Reconstruction of an acoustic pressure field in a resonance tube by particle image velocimetry.

PubMed

Kuzuu, K; Hasegawa, S

2015-11-01

A technique for estimating an acoustic field in a resonance tube is suggested. The estimation of an acoustic field in a resonance tube is important for the development of the thermoacoustic engine, and can be conducted employing two sensors to measure pressure. While this measurement technique is known as the two-sensor method, care needs to be taken with the location of pressure sensors when conducting pressure measurements. In the present study, particle image velocimetry (PIV) is employed instead of a pressure measurement by a sensor, and two-dimensional velocity vector images are extracted as sequential data from only a one- time recording made by a video camera of PIV. The spatial velocity amplitude is obtained from those images, and a pressure distribution is calculated from velocity amplitudes at two points by extending the equations derived for the two-sensor method. By means of this method, problems relating to the locations and calibrations of multiple pressure sensors are avoided. Furthermore, to verify the accuracy of the present method, the experiments are conducted employing the conventional two-sensor method and laser Doppler velocimetry (LDV). Then, results by the proposed method are compared with those obtained with the two-sensor method and LDV.

Project Career is an interprofessional five-year development project designed to improve the employment success of undergraduate college and university students with traumatic brain injury (TBI). The case study information was collected and synthesized by the project's Technology and Employment Coordinators (TECs) at each of the project's three university sites. The project's evaluation is occurring independently through JBS International, Inc. Five case studies are presented to provide an understanding of student participants' experiences within Project Career. Each case study includes background on the student, engagement with technology, vocational supports, and interactions with his/her respective TEC. A qualitative analysis from the student's case notes is provided within each case study, along with a discussion of the overall qualitative analysis. Across all five students, the theme Positive Outcomes was mentioned most often in the case notes. Of all the different type of challenges, Cognitive Challenges were most often mentioned during meetings with the TECs, followed by Psychological Challenges, Physical Challenges, Other Challenges, and Academic Challenges, respectively. Project Career is providing academic enrichment and career enhancement that may substantially improve the unsatisfactory employment outcomes that presently await students with TBI following graduation.

One of the most important rehabilitation goals is to return people with disabilities to paid employment. The purposes of this study were (1) to explore employment status and (2) to identify factors that may affect the employment outcomes of people with disabilities who received Disability Employment Services (DES). A retrospective study was conducted on clients who commenced and closed DES between January 2008 and December 2010 in a metropolitan city in Taiwan, using the files from the National Vocational Rehabilitation Services Documentary System. Sixty-nine percent (1,684 out of 2,452) of the clients in this study were engaged in paid employment after receiving DES. Logistic regression analyses indicated that clients with no psychiatric disability or mild impairment and with useful vocational qualifications, typical work experience, more post-employment services, and less pre-employment services were associated with a higher rate of successful employment outcomes. This study provides empirical evidence of the association between person- and DES-related factors and the employment outcomes of people with disabilities. Future improvements in health, school-to-work transition services, and vocational rehabilitation for people with disabilities should place more emphasis on providing work-based work experience, professional vocational training, access to college/professional education, career exploration, effective supported employment services, and other post-employment services.

Saavedra, Javier; López, Marcelino; Gonzáles, Sergio; Cubero, Rosario

2016-09-01

Employment has been highlighted as a determinant of health and as an essential milestone in the recovery process of people with serious mental illness. Different types of programs and public services have been designed to improve the employability of this population. However, there has not been much interest in the meanings attributed to these experiences and the negative aspects of work experience. In this research, we explored the meanings that participants attributed to their work experience and the impact of work on their recovery process. Research participants lived in Andalusia (Spain), a region in southern Europe with a high unemployment rate. Two versions of a semi-structured interview were designed: one for people who were working, and one for unemployed people. Participants' narratives were categorized according to grounded theory and the analyses were validated in group sessions. Apart from several positive effects for recovery, the analysis of the narratives about work experience outlined certain obstacles to recovery. For example, participants mentioned personal conflicts and stress, job insecurity and meaningless jobs. While valid, the idea that employment is beneficial for recovery must be qualified by the personal meanings attributed to these experiences, and the specific cultural and economic factors of each context.

Iconic memory requires attention

Persuh, Marjan; Genzer, Boris; Melara, Robert D.

2012-01-01

Two experiments investigated whether attention plays a role in iconic memory, employing either a change detection paradigm (Experiment 1) or a partial-report paradigm (Experiment 2). In each experiment, attention was taxed during initial display presentation, focusing the manipulation on consolidation of information into iconic memory, prior to transfer into working memory. Observers were able to maintain high levels of performance (accuracy of change detection or categorization) even when concurrently performing an easy visual search task (low load). However, when the concurrent search was made difficult (high load), observers' performance dropped to almost chance levels, while search accuracy held at single-task levels. The effects of attentional load remained the same across paradigms. The results suggest that, without attention, participants consolidate in iconic memory only gross representations of the visual scene, information too impoverished for successful detection of perceptual change or categorization of features.

Carlson, Joseph A.

2017-01-01

Strongly correlated quantum matter is ubiquitous in physics from cold atoms to nuclei to the cold dense matter found in neutron stars. Experiments from table-top to the extremely large scale experiments including FRIB and LIGO will help determine the properties of matter across an incredible scale of distances and energies. Questions to be addressed include the existence of exotic states of matter in cold atoms and nuclei, the response of this correlated matter to external probes, and the behavior of matter in extreme astrophysical environments. A more complete understanding is required, both to understand these diverse phenomena and to employ this understanding to probe for new underlying physics in experiments including neutrinoless double beta decay and accelerator neutrino experiments. I will summarize some aspects of our present understanding and highlight several important prospects for the future.

Opening the Conversation on REU Assessment and Evaluation

Pressley, S. N.; LeBeau, J. E.

2015-12-01

Project evaluation is a key component to ensuring success of any Research Experience for Undergraduates (REU) program. The Washington State University (WSU) Regional Atmospheric Chemistry: State-of-the-art Measurement and Modeling in the Pacific Northwest REU Site employs a mixed method approach to determine what is working well and what can use improvement (formative evaluation) and to determine impact and effectiveness of the project in reaching the stated goals (summative evaluation). Quantitative data is collected via a pre-/post-test measuring participants' research self-efficacy (RSE), motivation, background information, extent of socialization, and their interpretation of the value of the REU experience. Qualitative data is gathered through individual interviews with the REU students (at the beginning and end of the program) and faculty mentors (at the end). Beginning interviews focus on expectations for the REU program and student backgrounds. End interviews focus on student RSE development, interpretations of their experience, and the value of the experience. Faculty mentors are interviewed to gather insight on student performance in the program and perspectives on the overall success of the program in meeting the proposed goals. Students are provided an opportunity to comment on the strengths and weaknesses of workshops, providing critical feedback to the particular instructor and enabling the faculty to modify the workshop content and activities in future years. Finally, research results are evaluated during the final poster presentation, and faculty are interviewed to report on their perception of how each student learned and gained knowledge during the program. To evaluate the retention of students in engineering and science and identify chosen career paths, a longitudinal survey was created and it is administered via email each year. Many REU programs also employ the Undergraduate Research Students Self-Assessment (URSSA) online tool designed for evaluating REU experiences (University of Colorado at Boulder). Information presented in this presentation will include a discussion of the current tools used as described above as well as a discussion of the pros/cons of using URSSA. One of the concerns with using URSSA in conjunction with the other assessment tools is "survey fatigue".

Does evaluative conditioning depend on awareness? Evidence from a continuous flash suppression paradigm.

Högden, Fabia; Hütter, Mandy; Unkelbach, Christian

2018-02-26

The role of awareness in evaluative learning has been thoroughly investigated with a variety of theoretical and methodological approaches. We investigated evaluative conditioning (EC) without awareness with an approach that conceptually provides optimal conditions for unaware learning - the Continuous Flash Suppression paradigm (CFS). In CFS, a stimulus presented to one eye can be rendered invisible for a prolonged duration by presenting a high-contrast dynamic pattern to the other eye. The suppressed stimulus is nevertheless processed. First, Experiment 1 established EC effects in a pseudo-CFS setup without suppression. Experiment 2 then employed CFS to suppress conditioned stimuli (CSs) from awareness while the unconditioned stimuli (USs) were visible. While Experiment 1 and 2 used a between-participants manipulation of CS suppression, Experiments 3 and 4 both manipulated suppression within participants. We observed EC effects when CSs were not suppressed, but found no EC effects when the CS was suppressed from awareness. We relate our finding to previous research and discuss theoretical implications for EC. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The proportion of registered nurses (RNs) with employment in health-related positions before their initial RN education has increased in the past two decades. Previous research found that prior health-related employment is positively associated with RN workforce supply, potentially due to the wage differences based on different career paths. This study's objective is to test the hypotheses that prior health-related employment is associated with differences in starting wages and with different rates of wage growth for experience as an RN. We conducted a cross-sectional analysis using the 2008 National Sample Survey of Registered Nurses (NSSRN) linked with county-level variables from the Area Health Resource File. We estimated a Heckman model where the second-stage equation's outcome variable was the logarithm of the RN hourly wage, accounting for the self-selection of working or not working as an RN (i.e., the first-stage equation's outcome variable). Key covariates included interaction terms between years of experience, experience squared, and six categories of prior health-related employment (manager, LPN/LVN, allied health, nursing aide, clerk, and all other healthcare positions). Additional covariates included demographics, weekly working hours, marital status, highest nursing degree, and county-level variables (e.g., unemployment rate). We estimated the marginal effect of experience on wage for each type of prior health-related employment, conducting separate analyses for RNs whose initial education was a Bachelor of Science in Nursing (BSN) (unweighted N = 10,345/weighted N = 945,429), RNs whose initial education was an Associate degree (unweighted N = 13,791/weighted N = 1,296,809), and total population combining the former groups (unweighted N = 24,136/weighted N = 2,242,238). Prior health-related employment was associated with higher wages, with the strongest wage differences among BSN-educated RNs. Among BSN-educated RNs, previous employment as a health care manager, LPN/LVN, or nursing aide produced statistically higher starting wages ($1.72-$3.86 per hour; $3400-$7700 per year; p = 0.006-0.08). However, experience-based wage growth was lower for BSN-educated RNs previously employed as allied health workers, LPN/LVNs, or nursing aides. Among Associate degree-educated RNs, wage difference was not observed except for higher initial wage for RNs with previous employment as LPN/LVNs. Prior employment in health-related positions was associated with both starting salary and experience-based wage growth among BSN-educated RNs. The higher wage return for those with a BSN may motivate non-RN healthcare workers to seek a BSN in their transition to RN jobs, which could help advancement toward the 80 % BSN workforce recommended by the U.S. Institute of Medicine.

Work, employment, and mental illness: expanding the domain of Canadian social work.

Despite established evidence that work and employment are an important component of recovery for people who experience mental illness, social work education in Canada seldom offers graduate training or courses on the significance of work in peoples' lives or on the practices involved in helping to gain and retain employment for these individuals. In this article the authors argue that the high levels of unemployment among people who experience mental illness, and the rising incidence of mental health and addictions issues in workplaces, offer the opportunity, as well as the mandate, for social work educators to provide professional education in the area of employment support and assistance.

Are gay men and lesbians discriminated against when applying for jobs? A four-city, Internet-based field experiment.

PubMed

Bailey, John; Wallace, Michael; Wright, Bradley

2013-01-01

An Internet-based field experiment was conducted to examine potential hiring discrimination based on sexual orientation; specifically, the "first contact" between job applicants and employers was looked at. In response to Internet job postings on CareerBuilder.com®, more than 4,600 resumes were sent to employers in 4 U.S. cities: Philadelphia, Chicago, Dallas, and San Francisco. The resumes varied randomly with regard to gender, implied sexual orientation, and other characteristics. Two hypotheses were tested: first, that employers' response rates vary by the applicants' assumed sexuality; and second, that employers' Response Rates by Sexuality vary by city. Effects of city were controlled for to hold constant any variation in labor market conditions in the 4 cities. Based on employer responses to the applications, it was concluded that there is no evidence that gay men or lesbians are discriminated against in their first encounter with employers, and no significant variation across cities in these encounters was found. Implications of these results for the literature on hiring discrimination based on sexual orientation, the strengths and limitations of the research, and the potential for the Internet-based field experiment design in future studies of discrimination are discussed.

Objectives In countries with ageing populations, home care (HC) aides are among the fastest growing jobs. There are few quantitative studies of HC occupational safety and health (OSH) conditions. The objectives of this study were to: (1) assess quantitatively the OSH hazards and benefits for a wide range of HC working conditions, and (2) compare OSH experiences of HC aides who are employed via different medical and social services systems in Massachusetts, USA. Methods HC aides were recruited for a survey via agencies that employ aides and schedule their visits with clients, and through a labour union of aides employed directly by clients or their families. The questionnaire included detailed questions about the most recent HC visits, as well as about individual aides’ OSH experiences. Results The study population included 1249 HC aides (634 agency-employed, 615 client-employed) contributing information on 3484 HC visits. Hazards occurring most frequently related to musculoskeletal strain, exposure to potentially infectious agents and cleaning chemicals for infection prevention and experience of violence. Client-hired and agency-hired aides had similar OSH experiences with a few exceptions, including use of sharps and experience of verbal violence. Conclusions The OSH experience of HC aides is similar to that of aides in institutional healthcare settings. Despite OSH challenges, HC aides enjoy caring for others and the benefits of HC work should be enhanced. Quantification of HC hazards and benefits is useful to prioritise resources for the development of preventive interventions and to provide an evidence base for policy-setting. PMID:26209318

An examination of the frequency and impact of workplace sexual harassment on work, health, and school outcomes on high school girls is presented in two parts. The first compares the frequency of harassment in this sample (52%) to published research on adult women that used the same measure of sexual harassment. The second part compares outcomes for girls who experienced harassment versus those who did not. Students in a small, suburban high school for girls completed a paper and pencil survey during class. A modified version of the Sexual Experiences Questionnaire (SEQ: Fitzgerald et al., 1988) was used to identify sexually harassed working teenagers. Work attitudes, assessments of physical health and mental health, and school-related outcomes were measured using standardized scales. Data were analyzed using difference of proportions tests, t-tests, and regression. The percentage of harassed girls was significantly higher than the figures reported in most studies of working women. Girls who were sexually harassed were less satisfied with their jobs and supervisors, had higher levels of academic withdrawal, and were more apt to miss school than their non-harassed peers. Sexual harassment significantly impacts employed high school girls' connections to work and school. It not only taints their attitudes toward work but it also threatens to undermine their commitment to school. Educators, practitioners and community leaders should be aware of the negative impact this work experience may have on adolescents and explore these issues carefully with students who are employed outside of school. Teenage students, stressed by sexual harassment experienced at work may find their career development or career potential impeded or threatened due to school absence and poor academic performance. In addition, the physical safety of working students may be at risk, creating a need for teenagers to receive training to deal with sexual assault and other types of workplace violence. Educators, practitioners, and community leaders should be aware of the negative impact this work experience may have on adolescents and their overall school experience and explore the issue of sexual harassment carefully with students who are employed outside of school.

Enablers and challenges of post-16 education and employment outcomes: the perspectives of young adults with a history of SLI.

Research studies have begun to investigate the post-16 outcomes for young adults with a specific language impairment (SLI). As yet only tentative conclusions can be drawn with respect to academic and employment outcomes and the factors that are associated with more positive outcomes. Evidence for these findings has relied predominantly on associations between various language, academic and psychosocial assessments. Little attention has been paid to the perspective of the young person. To investigate from the perspective of a group of young people with a history of SLI the factors they believed have enabled and presented a challenge to their post-16 education and employment outcomes and experiences. Nineteen (four female, 15 male) young people aged from 19 to 23 years (average age 21 years), who had all attended the same residential special school for pupils with SLI, were interviewed face to face to explore their views as to what had enabled and limited their transition experiences to date. The data were analysed using thematic analysis. The majority of the young people saw themselves as key agents of change and very active participants in steering their own transition since leaving school. They acknowledged the important role played by their parents and families and how factors such as SLI had affected their transition experiences. The study supports evidence from research with different groups of young people with special educational needs (SEN) and disabilities of the importance of school and post-16 curriculums which develop agency on behalf of the young person. © 2012 Royal College of Speech and Language Therapists.

Coping and Sexual Harassment: How Victims Cope across Multiple Settings.

PubMed

Scarduzio, Jennifer A; Sheff, Sarah E; Smith, Mathew

2018-02-01

The ways sexual harassment occurs both online and in face-to-face settings has become more complicated. Sexual harassment that occurs in cyberspace or online sexual harassment adds complexity to the experiences of victims, current research understandings, and the legal dimensions of this phenomenon. Social networking sites (SNS) are a type of social media that offer unique opportunities to users and sometimes the communication that occurs on SNS can cross the line from flirtation into online sexual harassment. Victims of sexual harassment employ communicative strategies such as coping to make sense of their experiences of sexual harassment. The current study qualitatively examined problem-focused, active emotion-focused, and passive emotion-focused coping strategies employed by sexual harassment victims across multiple settings. We conducted 26 in-depth interviews with victims that had experienced sexual harassment across multiple settings (e.g., face-to-face and SNS). The findings present 16 types of coping strategies-five problem-focused, five active emotion-focused, and six passive emotion-focused. The victims used an average of three types of coping strategies during their experiences. Theoretical implications extend research on passive emotion-focused coping strategies by discussing powerlessness and how victims blame other victims. Furthermore, theoretically the findings reveal that coping is a complex, cyclical process and that victims shift among types of coping strategies over the course of their experience. Practical implications are offered for victims and for SNS sites.

Current high precision beta decay experiments of polarized neutrons, employing magnetic guiding fields in combination with position sensitive and energy dispersive detectors, resulted in a detailed study of the mono-energetic point spread function (PSF) for a homogeneous magnetic field. A PSF describes the radial probability distribution of mono-energetic electrons at the detector plane emitted from a point-like source. With regard to accuracy considerations, unwanted singularities occur as a function of the radial detector coordinate which have recently been investigated by subdividing the radial coordinate into small bins or employing analytical approximations. In this note, a series expansion of the PSFmore » is presented which can numerically be evaluated with arbitrary precision.« less

A variety of techniques may be used for photovoltaic energy systems. Concentrated or not concentrated sunlight may be employed, and a number of materials can be used, including silicon, gallium arsenide, cadmium sulfide, and cadmium telluride. Most of the experience, however, has been obtained with silicon cells employed without sunlight concentration. An industrial base exists at present for producing solar cells at a price in the range from $15 to $30 per peak watt. A major federal program has the objective to reduce the price of power provided by silicon solar systems to approximately $1 per peak watt in the early 1980's and $0.50 per watt by 1986. The approaches considered for achieving this objective are discussed.

Youth with learning disorders, speech/language disorders, and/or attention-deficit/hyperactivity disorder may experience significant struggles during the transition from high school to postsecondary education and employment. These disorders often occur in combination or concurrently with behavioral and emotional difficulties. Incomplete evaluation may not fully identify the factors underlying academic and personal challenges. This article reviews these disorders, the role of special education law for transitional age youth in public schools, and the Americans with Disabilities Act in postsecondary educational and employment settings. The role of the child and adolescent psychiatrist and the importance of advocacy for these youth are presented. Copyright © 2017 Elsevier Inc. All rights reserved.

A novel and simple ORAC methodology based on the interaction of Pyrogallol Red with peroxyl radicals.

PubMed

López-Alarcón, C; Lissi, E

2006-09-01

Oxygen radicals absorbance capacities (ORAC) indexes are frequently employed to characterize the radical trapping capacity of pure compounds and their complex mixtures. A drawback of ORAC values obtained using phycoerythrin, fluorescein (FL) or c-phycocyanin as targets, makes it possible to conclude that for very reactive compounds they are much more related to stoichiometric factors than to the reactivity of the tested compound. In the present paper, we propose a simple methodology, based on the bleaching of Pyrogallol Red (PGR) absorbance that provides ORAC indexes that are almost exclusively determined by the reactivity of the tested compounds. This difference is due to the high reactivity of PGR and the high concentrations of this compound employed in the experiments.

Results from a comparative study of the feasibility of employing experiment operators on the space shuttle to acquire scientifically worthwhile data are presented. The experiments performed during these tests included spectral observations of the Sun and Venus in the near ultraviolet region. The solar measurements were analyzed to determine ozone abundance in the terrestrial atmosphere. Using a detailed spectral matching technique to compare airborne solar UV measurements with synthetic spectral profiles of sunlight, it is deduced that in winter the total atmospheric ozone abundance is about 0.33 atm/cm at midlatitudes in the northern hemisphere.

2018-06-01

We applied a metacognitive approach to investigate confidence in recognition of prototypical faces. Participants were presented with sets of faces constructed digitally as deviations from prototype/base faces. Participants were then tested with a simple recognition task (Experiment 1) or a multiple-choice task (Experiment 2) for old and new items plus new prototypes, and they showed a high rate of confident false alarms to the prototypes. Confidence and accuracy relationship in this face recognition paradigm was found to be positive for standard items but negative for the prototypes; thus, it was contingent on the nature of the items used. The data have implications for lineups that employ match-to-suspect strategies.

2016-10-24

The first simulations employing a kinetic treatment of both fuel and shell ions to model inertial confinement fusion experiments are presented, including results showing the importance of kinetic physics processes in altering fusion burn. A pair of direct drive capsule implosions performed at the OMEGA facility with two different gas fills of deuterium, tritium, and helium-3 are analyzed. During implosion shock convergence, highly non-Maxwellian ion velocity distributions and separations in the density and temperature amongst the ion species are observed. Finally, diffusion of fuel into the capsule shell is identified as a principal process that degrades fusion burn performance.

MINERvA is a few-GeV neutrino scattering experiment that has been taking data in the NuMI beam line at Fermilab since November 2009. The experiment will provide important inputs, both in support of neutrino oscillation searches and as a pure weak probe of the nuclear medium. For this, MINERvA employs a fine-grained detector, with an eight ton active target region composed of plastic scintillator and a suite of nuclear targets composed of helium, carbon, iron, lead and water placed upstream of the active region. In this talk, we present the current status of the charged current inclusive analysis for neutrinos and antineutrinos in plastic scintillator.

The use of carbon fiber composites under shock and impact loading in aerospace, defense and automotive applications is increasingly important. Therefore prediction of the composite behavior and damage in these conditions is critical. Influence of anisotropy, fiber orientation and the rate of loading during the impact is considered in the present study and validated by comparison with experiments. The experiments deal with the plane, ballistic and Taylor impacts accompanied by high-speed photography observations and tomography of recovered samples. The CTH hydrocode is employed as the modeling platform with an advanced rate sensitive material model used for description of the deformation and damage of the transversely isotropic composite material.

A pulsed monochromatic beam strikes the sample, and the energies of scattered neutrons are determined from their times-of-flight to an array of detectors. The time-of-flight method may be used in a variety of types of experiments such as studies of vibrational and magnetic excitations, tunneling spectroscopy, and quasielastic scattering studies of diffusional behavior; several examples of experiments are discussed. We also present brief descriptions of the CNRF time-of-flight instruments, including their modi operandi and some of their more pertinent parameters and performance characteristics. PMID:28053459

In response to increased risks of second-hand smoke exposure for children travelling in cars and its resulting deleterious health impacts, several jurisdictions passed legislation that bans smoking in private vehicles when children are present. In this study, I exploit a unique quasi-experiment from Canada and employ the difference-in-differences and triple-differences techniques to empirically evaluate this legislation. I find that the legislation reduces exposure to second-hand smoke inside cars for children. Further, there appears no marked increase in smoking at home after the implementation of the legislation.

Oculomotor Examination of the Weapon Focus Effect: Does a Gun Automatically Engage Visual Attention?

PubMed Central

Flowe, Heather D.; Hope, Lorraine; Hillstrom, Anne P.

2013-01-01

Background A person is less likely to be accurately remembered if they appear in a visual scene with a gun, a result that has been termed the weapon focus effect (WFE). Explanations of the WFE argue that weapons engage attention because they are unusual and/or threatening, which causes encoding deficits for the other items in the visual scene. Previous WFE research has always embedded the weapon and nonweapon objects within a larger context that provides information about an actor's intention to use the object. As such, it is currently unknown whether a gun automatically engages attention to a greater extent than other objects independent of the context in which it is presented. Method Reflexive responding to a gun compared to other objects was examined in two experiments. Experiment 1 employed a prosaccade gap-overlap paradigm, whereby participants looked toward a peripheral target, and Experiment 2 employed an antisaccade gap-overlap paradigm, whereby participants looked away from a peripheral target. In both experiments, the peripheral target was a gun or a nonthreatening object (i.e., a tomato or pocket watch). We also controlled how unexpected the targets were and compared saccadic reaction times across types of objects. Results A gun was not found to differentially engage attention compared to the unexpected object (i.e., a pocket watch). Some evidence was found (Experiment 2) that both the gun and the unexpected object engaged attention to a greater extent compared the expected object (i.e., a tomato). Conclusion An image of a gun did not engage attention to a larger extent than images of other types of objects (i.e., a pocket watch or tomato). The results suggest that context may be an important determinant of WFE. The extent to which an object is threatening may depend on the larger context in which it is presented. PMID:24349028

How Mobile App Design Impacts User Responses to Mixed Self-Tracking Outcomes: Randomized Online Experiment to Explore the Role of Spatial Distance for Hedonic Editing

PubMed Central

Lorenz, Jana

2018-01-01

Background Goal setting is among the most common behavioral change techniques employed in contemporary self-tracking apps. For these techniques to be effective, it is relevant to understand how the visual presentation of goal-related outcomes employed in the app design affects users’ responses to their self-tracking outcomes. Objective This study examined whether a spatially close (vs distant) presentation of mixed positive and negative self-tracking outcomes from multiple domains (ie, activity, diet) on a digital device’s screen can provide users the opportunity to hedonically edit their self-tracking outcome profile (ie, to view their mixed self-tracking outcomes in the most positive light). Further, this study examined how the opportunity to hedonically edit one’s self-tracking outcome profile relates to users’ future health behavior intentions. Methods To assess users’ responses to a spatially close (vs distant) presentation of a mixed-gain (vs mixed-loss) self-tracking outcome profile, a randomized 2×2 between-subjects online experiment with a final sample of 397 participants (mean age 27.4, SD 7.2 years; 71.5%, 284/397 female) was conducted in Germany. The experiment started with a cover story about a fictitious self-tracking app. Thereafter, participants saw one of four manipulated self-tracking outcome profiles. Variables of interest measured were health behavior intentions, compensatory health beliefs, health motivation, and recall of the outcome profile. We analyzed data using chi-square tests (SPSS version 23) and moderated mediation analyses with the PROCESS macro 2.16.1. Results Spatial distance facilitated hedonic editing, which was indicated by systematic memory biases in users’ recall of positive and negative self-tracking outcomes. In the case of a mixed-gain outcome profile, a spatially close (vs distant) presentation tended to increase the underestimation of the negative outcome (P=.06). In the case of a mixed-loss outcome profile, a spatially distant (vs close) presentation facilitated the exact recognition of the positive outcome (P=.04). When the presentation of self-tracking outcomes provided the opportunity for hedonic editing, users with a low (vs high) health motivation produced compensatory health beliefs, which led to lower health behavior intentions (index of moderated mediation=0.0352, 95% CI 0.0011-0.0923). Conclusions When spatial distance between the presentations of mixed self-tracking outcomes provided the opportunity to hedonically edit one’s self-tracking outcome profile, users recalled their self-tracking outcomes in a more positive light. Especially for users with lower health motivation, the opportunity to hedonically edit one’s mixed self-tracking outcome profile led to reduced health behavior intentions. To prevent the occurrence of hedonic editing in users’ responses to visually presented self-tracking outcome profiles, further research is necessary to determine the ideal distance that should be employed in the app design for the presentation of mixed self-tracking outcomes on a digital device’s screen.

Employment of Geoscientists in the Private Sector

NASA Astrophysics Data System (ADS)

Russell, J. L.

2001-05-01

In the private sector, major employers of geoscientists engage in diverse activities ranging from resource exploration and extraction, assessment of geologic hazards, and determination of environmental impacts. These firms actively recruit, from the breadth of geoscience disciplines, technically qualified individuals with the ability to make pragmatic decisions in the context of multidisciplinary teams that commonly include non-scientists. Moreover, they expect applicants to communicate effectively verbally and in writing, as well as demonstrate skills and experience in integrating field investigations, conducting laboratory studies, and accomplishing computer modeling. These applicants should be capable of simultaneously working in multiple projects which are rapidly evolving. Successful recruiting and employment requires interactions between the job applicant and potential employer conducted with honesty and integrity. Resumes and associated transmittal letters should be directed to specific employers based on the applicant's review of information on the firm from the Internet and other sources. "Shotgun" or blanket approaches are seldom productive. Participation in pertinent professional societies, internships, and summer employment can provide valuable experiences and opportunities for networking with potential employers.

What are the experiences of people with dementia in employment?

PubMed

Chaplin, Ruth; Davidson, Ian

2016-03-01

Statistics show that an increase in the statutory retirement age in the UK will mean that many more people will develop a dementia while still in employment. A review of the literature confirmed that there are no existing studies in the UK which examine this issue in any detail. The aim of this study was to investigate the experiences of people who develop a dementia while still in employment and to understand how they make sense of these experiences; therefore a qualitative explorative inquiry based on an Interpretive Phenomenological Analysis methodology was used. Interviews with five people who had developed a dementia while still in employment were carried out, with ages ranging from 58 to 74 years. Interview transcripts were analysed and four super-ordinate themes were identified: the realization that something is wrong; managing the situation in the workplace; trying to make sense of change; and coming to terms with retirement or unemployment. The results showed that people who develop a dementia while still in employment do not always receive the 'reasonable adjustments' in the workplace to which they are entitled under the Equality Act (2010). Some of the participants felt that they were poorly treated by their workplace and described some distressing experiences. The study highlights the need for more effective specialized advice and support regarding employment issues and more research into the numbers of people in the UK that are affected by this issue. © The Author(s) 2014.

Enhancing audiovisual experience with haptic feedback: a survey on HAV.

PubMed

Danieau, F; Lecuyer, A; Guillotel, P; Fleureau, J; Mollet, N; Christie, M

2013-01-01

Haptic technology has been widely employed in applications ranging from teleoperation and medical simulation to art and design, including entertainment, flight simulation, and virtual reality. Today there is a growing interest among researchers in integrating haptic feedback into audiovisual systems. A new medium emerges from this effort: haptic-audiovisual (HAV) content. This paper presents the techniques, formalisms, and key results pertinent to this medium. We first review the three main stages of the HAV workflow: the production, distribution, and rendering of haptic effects. We then highlight the pressing necessity for evaluation techniques in this context and discuss the key challenges in the field. By building on existing technologies and tackling the specific challenges of the enhancement of audiovisual experience with haptics, we believe the field presents exciting research perspectives whose financial and societal stakes are significant.

Advances in NIF Shock Timing Experiments

NASA Astrophysics Data System (ADS)

Robey, Harry

2012-10-01

Experiments are underway to tune the shock timing of capsule implosions on the National Ignition Facility (NIF). These experiments use a modified cryogenic hohlraum geometry designed to precisely match the performance of ignition hohlraums. The targets employ a re-entrant Au cone to provide optical access to multiple shocks as they propagate in the liquid deuterium-filled capsule interior. The strength and timing of all four shocks is diagnosed with VISAR (Velocity Interferometer System for Any Reflector). Experiments are now routinely conducted in a mirrored keyhole geometry, which allows for simultaneous diagnosis of the shock timing at both the hohlraum pole and equator. Further modifications are being made to improve the surrogacy to ignition hohlraums by replacing the standard liquid deuterium (D2) capsule fill with a deuterium-tritium (DT) ice layer. These experiments will remove any possible surrogacy difference between D2 and DT as well as incorporate the physics of shock release from the ice layer, which is absent in current experiments. Experimental results and comparisons with numerical simulation are presented.

Knowing and learning about science in a preservice setting: A narrative study

NASA Astrophysics Data System (ADS)

Mulholland, Judith; Wallace, John

1994-12-01

This study employs narrative methods to give a holistic view of the experiences of five mature age preservice teachers in a semester unit of science education. The unit was designed to help teachers examine and make explicit their ideas about science and science teaching and consider ways in which they might put those ideas into practice. The pivotal theme, around which the teachers' experiences could be organised, was found to be learning science. The preservice teachers expressed a need for a supportive learning environment in which concepts were built gradually and introduced using concrete examples. Previous science experience was found to be a major influence on the attitudes the participants brought to the present course. A lack of previous experience or negative past experiences were a major cause of anxiety. Gender was also important as it had limited the science experiences available to some participants in the past and continued to influence the way they participated in classes during the semester.

The role of self-esteem in the misinformation effect.

PubMed

Saunders, Jo

2012-01-01

Previous research using the Gudjonnson suggestibility scale has suggested a role for self-esteem in suggestibility, with participants low in self-esteem being more suggestible than participants high in self-esteem. Four experiments are presented examining the role of self-esteem in the misinformation effect and whether enhanced suggestibility effects in participants low in self-esteem reflect genuine memory impairment. In Experiments 1 and 4 participants completed a standard recognition test. In Experiment 2 participants completed the modified recognition test. In Experiment 3 participants completed a free recall test. In Experiments 1 and 4 participants low in self-esteem demonstrated greater misinformation effects than participants high in self-esteem. In Experiment 3 a 3-day retention interval was employed with the modified test and no differences were found between the two groups on the reporting of the new item. The findings suggest that participants low in self-esteem are particularly sensitive to demand characteristics and post-event suggestion but do not suffer from genuine memory impairment.

Installation effects on the tonal noise generated by axial flow fans

NASA Astrophysics Data System (ADS)

Canepa, Edward; Cattanei, Andrea; Mazzocut Zecchin, Fabio

2015-03-01

The paper presents the results of experiments on a low-speed axial-flow fan flush mounted on flat panels typically employed in tests on automotive cooling fans. The experiments have been conducted in a hemi-anechoic chamber and were aimed at evaluating the installation effects of the whole test configuration, including chamber floor and size and shape of the mounting panel. The largest panels cause important SPL variations in a narrow, low frequency range. Their effect on the propagation function has been verified by means of parametric BEM computations. A regular wavy trend associated with reflections from the floor is also present. In both cases, the tonal noise is more strongly affected than the broadband one. The analysis is performed by means of an existing spectral decomposition technique and a new one, which allows to consider different noise generating mechanisms and also to separate the emitted tonal and broadband noise from the associated propagation effects. In order to better identify the features of the noise at the blade passing frequency (BPF) harmonics, the phase of the acoustic pressure is also analysed. Measurements are taken during speed ramps, which allow to obtain both constant-Strouhal number SPL data and constant-speed data. The former data set is employed in the new technique, while the latter may be employed in the standard spectral decomposition techniques. Based on both the similarity theory and the analysis of the Green's function of the problem, a theoretical description of the structure of the received SPL spectrum is given. Then, the possibility of discriminating between tonal and broadband noise generating mechanisms is analysed and a theoretical base for the new spectral decomposition technique is provided.

NASA Astrophysics Data System (ADS)

Degl'Innocenti, R.; Zanotto, S.; Tredicucci, A.; Biasiol, G.; Sorba, L.

2011-12-01

We present the observation of the strong light-matter coupling regime between intersubband transitions of semiconductor quantum wells and the plasmonic-like resonances of a one dimensional metallic grating. Polariton spectra have been recorded in transmission employing a suspended membrane sample and are consistent with theoretical calculations. This arrangement, avoiding the complexity of dispersive substrate, is particularly attractive for the development of time-resolved pump-probe experiments.

Niu, Ruican; Jiao, L. C.; Wang, Guiting; Feng, Jie

2011-12-01

A new method of change detection in SAR images based on spectral clustering is presented in this paper. Spectral clustering is employed to extract change information from a pair images acquired on the same geographical area at different time. Watershed transform is applied to initially segment the big image into non-overlapped local regions, leading to reduce the complexity. Experiments results and system analysis confirm the effectiveness of the proposed algorithm.

The experiences of urban, professional women when combining breastfeeding with paid employment in Karachi, Pakistan: a qualitative study.

PubMed

Hirani, Shela Akbar Ali; Karmaliani, Rozina

2013-06-01

Pakistan has the second highest child mortality rate in South Asia. Breastfeeding can promote infant health, prevent infection and possibly mortality. However, a gradual decline in breastfeeding is reported for Pakistan; especially among urban, educated, employed women. Little research exists regarding the experiences of professional women in Pakistan who are breastfeeding and employed. To describe the experiences of urban, professional women who breastfeed and are employed, as related to facilitators and barriers of breastfeeding. Using a qualitative descriptive design, nine full-time employed women were recruited through purposive sampling from a private tertiary care health setting in Karachi, Pakistan. A pre-tested, semi-structured interview guide was used for an in-depth interview of 40-45min with each participant. Most women spoke about the challenges of combining breastfeeding with employment, which resulted in early cessation of breastfeeding. The study indicated that positive maternal attributes such as knowledge about breastfeeding, planning, self-commitment, and open communication, as well as availability of social and workplace support is essential to enable urban, professional women in Pakistan to continue breastfeeding while employed. Pakistan has high infant and child mortality rate and decreasing prevalence of breastfeeding, especially among employed professional women. Our findings indicate an urgent need for lactation support programs that include integrated interventions for lactating women that offer informational support, social support, and formal workplace support.

Leinonen, Taina; Mäki, Netta; Martikainen, Pekka

2017-01-01

The unemployed more often suffer from depression than the employed. We examined whether mental health deterioration occurs already before unemployment implicating health selection, or whether it mostly occurs after becoming exposed to the experience rendering causal explanations more likely. We used nationally representative Finnish register data to examine changes in depressive morbidity as measured by antidepressant medication in 1995-2009 over four years before and since a new onset of unemployment (N = 28 000) at the age of 30-60 compared to the employed (N = 124 136). We examined separately those who became continuously long-term unemployed, intermittently unemployed and unemployed with eventual re-employment in the second, third or fourth year since the year of onset. Annual repeated measurements were analysed using generalised estimation equations. Among the employed antidepressant medication increased slowly but steadily over the study period and it was mainly at a lower level than among the unemployed. In the four years leading to unemployment there was excess increase in medication that was generally stronger among those with longer duration of the eventual unemployment experience. During unemployment medication decreased in all groups except among the intermittently unemployed. By the first year of re-employment antidepressant medication reached a level similar to that among the employed and afterwards followed no consistent trend. The associations of unemployment and re-employment with depressive morbidity appear to be largely driven by health selection. The question of potential causal associations remains unresolved for intermittent unemployment in particular.

The impact of arthritis on the early employment experiences of young adults: A literature review.

PubMed

Jetha, Arif

2015-07-01

Young adulthood is an important transitional life phase that can determine a person's career trajectory. To date, little research has examined the influence of arthritis on early work experiences. This literature review aims at examining the impact of arthritis on the early career phase of young adults and identifying the barriers to employment. Two independent reviewers searched bibliographic databases for arthritis conditions and a series of employment-related keywords and subject headings. Information on authors, publication year; study design, sample characteristics (e.g., number of participants, age, gender, arthritis type); work outcomes measured; and specific barriers to employment was recorded. Nine studies were uncovered in the review. All studies examined young people with juvenile arthritis (9 of 9 studies) and consisted of sample sizes with less then 150 participants (6 of 9 studies) who were primarily recruited from clinics (7 of 9 studies). All were cross-sectional designs. Employment status was primarily examined and ranged from 11% to 71%. Although not always statistically significant, young adults with arthritis were less likely to be employed when compared to their healthy peers. Greater disease severity, less educational attainment and being female were related to not participating in paid work. This review brings to light the paucity of studies examining the early employment experiences of young adults with arthritis. There is a need to expand research to contribute to recommendations for sustained and productive employment across the working life course. Copyright © 2015 Elsevier Inc. All rights reserved.

Communicating with employers: experiences of occupational therapists treating people with musculoskeletal conditions.

PubMed

Coole, Carol; Birks, Emily; Watson, Paul J; Drummond, Avril

2014-09-01

Many employed people with musculoskeletal conditions rely on healthcare practitioners, including occupational therapists, for work-related advice and support. Good communication between healthcare practitioners and employers is considered vital in facilitating work retention and return to work. The purpose of this study was to explore the experiences of occupational therapists in communicating with patients' employers. Qualitative data were collected from the responses of occupational therapists to ten statements/open questions in a questionnaire survey of UK occupational therapists. Data were copied verbatim into word documents and analysed thematically. A total of 649 comments were made by 143 respondents. Five themes were identified that were associated with communicating with employers: patient-dependent; employer-dependent; therapist-dependent; extrinsic factors; methods of communication. This study has identified that communication between occupational therapists and employers is influenced by a number of factors, including those which are outside the therapists' control. These need to be acknowledged and addressed by therapists, their professional organisation, employers, commissioners, therapy service managers, educators and employees in order to support return-to-work and work retention of people with musculoskeletal conditions.

A loophole-free Bell's inequality experiment

NASA Astrophysics Data System (ADS)

Kwiat, Paul G.; Steinberg, Aephraim M.; Chiao, Raymond Y.; Eberhard, Philippe H.

1994-05-01

The proof of Nature's nonlocality through Bell-type experiments is a topic of longstanding interest. Nevertheless, no experiments performed thus far have avoided the so-called 'detection loophole,' arising from low detector efficiencies and angular-correlation difficulties. In fact, most, if not all, of the systems employed to date can never close this loophole, even with perfect detectors. In addition, another loophole involving the non-rapid, non-random switching of various parameter settings exists in all past experiments. We discuss a proposal for a potentially loophole-free Bell's inequality experiment. The source of the EPR-correlated pairs consists of two simultaneously-pumped type-2 phase-matched nonlinear crystals and a polarizing beam splitter. The feasibility of such a scheme with current detector technology seems high, and will be discussed. We also present a single-crystal version, motivated by other work presented at this conference. In a separate experiment, we have measured the absolute detection efficiency and time response of four single-photon detectors. The highest observed efficiencies were 70.7 plus or minus 1.9 percent (at 633 nm, with a device from Rockwell International) and 76.4 plus or minus 2.3 percent (at 702 nm, with an EG&G counting module). Possible efficiencies as high as 90 percent were implied. The EG&G devices displayed sub-nanosecond time resolution.

Miniature GC-Minicell Ion Mobility Spectrometer (IMS) for In Situ Measurements in Astrobiology Planetary Missions

NASA Technical Reports Server (NTRS)

Kojiro, Daniel R.; Stimac, Robert M.; Kaye, William J.; Holland, Paul M.; Takeuchi, Norishige

2006-01-01

Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or ionger mission life for stationary landers/laboratories. The miniCometary Ice and Dust Experiment (miniCIDEX), which combined Gas Chromatography (GC) with helium Ion Mobility Spectrometry (IMS), was capable of providing the wide range of analytical information required for Astrobiology missions. The IMS used here was based on the PCP model 111 IMS. A similar system, the Titan Ice and Dust Experiment (TIDE), was proposed as part of the Titan Orbiter Aerorover Mission (TOAM). Newer GC systems employing Micro Electro- Mechanical System (MEMS) based technology have greatly reduced both the size and resource requirements for space GCs. These smaller GCs, as well as the continuing miniaturization of Astrobiology analytical instruments in general, has highlighted the need for smaller, dry helium IMS systems. We describe here the development of a miniature, MEMS GC-IMS system (MEMS GC developed by Thorleaf Research Inc.), employing the MiniCell Ion Mobility Spectrometer (IMS), from Ion Applications Inc., developed through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA s Small Business Innovative Research (SBIR) Program.

The Value of "Experience" and the labour market entry of new immigrants to Canada.

PubMed

Hall, Peter V; Sadouzai, Tulin

2010-01-01

We use data from three waves of the Longitudinal Survey of Immigrants to Canada to compare how pre-immigration experience in hi-tech and regulated occupations affects employment outcomes. While differences do decline over time, those with experience in an unregulated hi-tech occupation are more likely to be employed sooner in a matching and/or full time job. Immigrants with hi-tech occupational experience are more likely to have their foreign experience accepted, possibly due to the transferability of these skills and the absence of institutional barriers. These findings indicate important sectoral, regulatory, and institutional differences in the treatment of pre-immigration experience, with policy implications.

Zhang, Lei; Feng, Lixin

2018-06-01

The inverse medium problem with discontinuous refractive index is a kind of challenging inverse problem. We employ the primal dual theory and fast solution of integral equations, and propose a new iterative imaging method. The selection criteria of regularization parameter is given by the method of generalized cross-validation. Based on multi-frequency measurements of the scattered field, a recursive linearization algorithm has been presented with respect to the frequency from low to high. We also discuss the initial guess selection strategy by semi-analytical approaches. Numerical experiments are presented to show the effectiveness of the proposed method.

Optimizing the milling characteristics of Al-SiC particulate composites

NASA Astrophysics Data System (ADS)

Karthikeyan, R.; Raghukandan, K.; Naagarazan, R. S.; Pai, B. C.

2000-12-01

The present investigation focuses on the face milling characteristics of LM25Al-SiC particulate composites produced through stir casting. Experiments were conducted according to an L27 orthogonal array and mathematical models were developed for such machining characteristics as flank wear, specific energy and surface roughness whose adequacy was checked. The insignificant effects present in the models were eliminated using a t-test. Goal programming was employed to optimize the cutting conditions by considering such primary objectives as maximizing the metal removal rate and minimizing tool wear, specific energy and surface roughness.

Perception of Simultaneous Auditive Contents

NASA Astrophysics Data System (ADS)

Tschinkel, Christian

Based on a model of pluralistic music, we may approach an aesthetic concept of music, which employs dichotic listening situations. The concept of dichotic listening stems from neuropsychological test conditions in lateralization experiments on brain hemispheres, in which each ear is exposed to a different auditory content. In the framework of such sound experiments, the question which primarily arises concerns a new kind of hearing, which is also conceivable without earphones as a spatial composition, and which may superficially be linked to its degree of complexity. From a psychological perspective, the degree of complexity is correlated with the degree of attention given, with the listener's musical or listening experience and the level of his appreciation. Therefore, we may possibly also expect a measurable increase in physical activity. Furthermore, a dialectic interpretation of such "dualistic" music presents itself.

An investigation of ESSA 7 radiation data for use in long-term earth energy experiments, phases 1 and 2

1974-01-01

The results are presented of an investigation of ESSA 7 satellite radiation data for use in long-term earth energy experiments. Satellite systems for performing long-term earth radiation balance measurements over geographical areas, hemispheres, and the entire earth for periods of 10 to 30 years are examined. The ESSA 7 satellite employed plate and cone radiometers to measure earth albedo and emitted radiation. Each instrument had a black and white radiometer which discriminated the components of albedo and emitted radiation. Earth measurements were made continuously from ESSA 7 for ten months. The ESSA 7 raw data is processed to a point where it can be further analyzed for: (1) development of long-term earth energy experiments; and (2) document climate trends.

Distributed control using linear momentum exchange devices

Sharkey, J. P.; Waites, Henry; Doane, G. B., III

1987-01-01

MSFC has successfully employed the use of the Vibrational Control of Space Structures (VCOSS) Linear Momentum Exchange Devices (LMEDs), which was an outgrowth of the Air Force Wright Aeronautical Laboratory (AFWAL) program, in a distributed control experiment. The control experiment was conducted in MSFC's Ground Facility for Large Space Structures Control Verification (GF/LSSCV). The GF/LSSCV's test article was well suited for this experiment in that the LMED could be judiciously placed on the ASTROMAST. The LMED placements were such that vibrational mode information could be extracted from the accelerometers on the LMED. The LMED accelerometer information was processed by the control algorithms so that the LMED masses could be accelerated to produce forces which would dampen the vibrational modes of interest. Experimental results are presented showing the LMED's capabilities.

This study explored the impact of The Open University's (OU) preregistration nursing programme on students' employability, career progression and its contribution to developing the nursing workforce across the United Kingdom. Designed for healthcare support workers who are sponsored by their employers, the programme is the only part-time supported open/distance learning programme in the UK leading to registration as a nurse. The international literature reveals that relatively little is known about the impact of previous experience as a healthcare support worker on the experience of transition, employability skills and career progression. To identify alumni and employer views of the perceived impact of the programme on employability, career progression and workforce development. A qualitative design using telephone interviews which were digitally recorded, and transcribed verbatim prior to content analysis to identify recurrent themes. Three geographical areas across the UK. Alumni (n=17) and employers (n=7). Inclusion criterion for alumni was a minimum of two years' post-qualifying experience. Inclusion criteria for employers were those that had responsibility for sponsoring students on the programme and employing them as newly qualified nurses. Four overarching themes were identified: transition, expectations, learning for and in practice, and flexibility. Alumni and employers were of the view that the programme equipped them well to meet the competencies and expectations of being a newly qualified nurse. It provided employers with a flexible route to growing their own workforce and alumni the opportunity to achieve their ambition of becoming a qualified nurse when other more conventional routes would not have been open to them. Some of them had already demonstrated career progression. Generalising results requires caution due to the small, self-selecting sample but findings suggest that a widening participation model of pre-registration nurse education for employed healthcare support workers more than adequately prepares them for the realities of professional practice.

Hiring a Gay Man, Taking a Risk?: A Lab Experiment on Employment Discrimination and Risk Aversion.

PubMed

Baert, Stijn

2018-01-01

We investigate risk aversion as a driver of labor market discrimination against homosexual men. We show that more hiring discrimination by more risk-averse employers is consistent with taste-based and statistical discrimination. To test this hypothesis we conduct a scenario experiment in which experimental employers take a fictitious hiring decision concerning a heterosexual or homosexual male job candidate. In addition, participants are surveyed on their risk aversion and other characteristics that might correlate with this risk aversion. Analysis of the (post-)experimental data confirms our hypothesis. The likelihood of a beneficial hiring decision for homosexual male candidates decreases by 31.7% when employers are a standard deviation more risk-averse.

Ballistic Experiments with Titanium and Aluminum Targets

During the course of the project we conducted two sets of fundamental experiments in penetration mechanics in the LLNL Terminal Ballistics Laboratory of the Physics Directorate. The first set of full-scale experiments was conducted with a 14.5mm air propelled launcher. The object of the experiments was to determine the ballistic limit speed of 6Al-4V-alloy titanium, low fineness ratio projectiles centrally impacting 2024-T3 alloy aluminum flat plates and the failure modes of the projectiles and the targets. The second set of one-third scale experiments was conducted with a 14.5mm powder launcher. The object of these experiments was to determine the ballisticmore » limit speed of 6Al-4V alloy titanium high fineness ratio projectiles centrally impacting 6Al-4V alloy titanium flat plates and the failure modes of the projectiles and the target. We employed radiography to observe a projectile just before and after interaction with a target plate. Early on, we employed a non-damaging ''soft-catch'' technique to capture projectiles after they perforated targets. Once we realized that a projectile was not damaged during interaction with a target, we used a 4-inch thick 6061-T6-alloy aluminum witness block with a 6.0-inch x 6.0-inch cross-section to measure projectile residual penetration. We have recorded and tabulated below projectile impact speed, projectile residual (post-impact) speed, projectile failure mode, target failure mode, and pertinent comments for the experiments. The ballistic techniques employed for the experiments are similar to those employed in an earlier study.« less

Continuous recognition of spatial and nonspatial stimuli in hippocampal-lesioned rats.

Jackson-Smith, P; Kesner, R P; Chiba, A A

1993-03-01

The present experiments compared the performance of hippocampal-lesioned rats to control rats on a spatial continuous recognition task and an analogous nonspatial task with similar processing demands. Daily sessions for Experiment 1 involved sequential presentation of individual arms on a 12-arm radial maze. Each arm contained a Froot Loop reinforcement the first time it was presented, and latency to traverse the arm was measured. A subset of the arms were repeated, but did not contain reinforcement. Repeated arms were presented with lags ranging from 0 to 6 (0 to 6 different arm presentations occurred between the first and the repeated presentation). Difference scores were computed by subtracting the latency on first presentations from the latency on repeated presentations, and these scores were high in all rats prior to surgery, with a decreasing function across lag. There were no differences in performance following cortical control or sham surgery. However, there was a total deficit in performance following large electrolytic lesions of the hippocampus. The second experiment employed the same continuous recognition memory procedure, but used three-dimensional visual objects (toys, junk items, etc., in various shapes, sizes, and textures) as stimuli on a flat runway. As in Experiment 1, the stimuli were presented successively and latency to run to and move the object was measured. Objects were repeated with lags ranging from 0 to 4. Performance on this task following surgery did not differ from performance prior to surgery for either the control group or the hippocampal lesion group. These results provide support for Kesner's attribute model of hippocampal function in that the hippocampus is assumed to mediate data-based memory for spatial locations, but not three-dimensional visual objects.

A laser device for fusion of nasal mucosa

NASA Astrophysics Data System (ADS)

Sooklal, Valmiki; McClure, Jesse; Hooper, Luke; Larson, Michael

2010-02-01

A prototype device has been created to fuse septal tissue membranes as an alternative to sutures or staples through the controlled application of laser heating and pressure to induce protein denaturation and subsequent tissue fusion, through renaturation and intertwining, across the interface. Lasers have been used to close wounds in controlled laboratory tests over the last 15 years. Many encouraging results have been obtained; however, no commercial delivery systems are currently available. This is due primarily to two factors: requiring an inordinate amount of experience on the part of the operator, and attempting to achieve general applicability for multiple tissue systems. The present device overcomes these barriers as it is tailored for the particular application of septal laser fusion, namely for the coaptation of mucoperichondrial membranes. The important parameters involved in fusing biological tissues are identified. The development of the device followed from computational modeling based on Monte Carlo simulation of photon transport and on engineering firstprinciples. Experiments were designed and analyzed using orthogonal arrays, employing a subset of the relevant parameters, i.e., laser irradiance, dwell time and spot size, for a range of wavelengths. The in vitro fusion experiments employed 1cm by 1cm sections of equine nasal mucosa having a nominal thickness of 1mm.

TRANSFER OF AVERSIVE RESPONDENT ELICITATION IN ACCORDANCE WITH EQUIVALENCE RELATIONS

PubMed Central

Valverde, Miguel RodrÍguez; Luciano, Carmen; Barnes-Holmes, Dermot

2009-01-01

The present study investigates the transfer of aversively conditioned respondent elicitation through equivalence classes, using skin conductance as the measure of conditioning. The first experiment is an attempt to replicate Experiment 1 in Dougher, Augustson, Markham, Greenway, and Wulfert (1994), with different temporal parameters in the aversive conditioning procedure employed. Match-to-sample procedures were used to teach 17 participants two 4-member equivalence classes. Then, one member of one class was paired with electric shock and one member of the other class was presented without shock. The remaining stimuli from each class were presented in transfer tests. Unlike the findings in the original study, transfer of conditioning was not achieved. In Experiment 2, similar procedures were used with 30 participants, although several modifications were introduced (formation of five-member classes, direct conditioning with several elements of each class, random sequences of stimulus presentation in transfer tests, reversal in aversive conditioning contingencies). More than 80% of participants who had shown differential conditioning also showed the transfer of function effect. Moreover, this effect was replicated within subjects for 3 participants. This is the first demonstration of the transfer of aversive respondent elicitation through stimulus equivalence classes with the presentation of transfer test trials in random order. The latter prevents the possibility that transfer effects are an artefact of transfer test presentation order. PMID:20119523

Experiences of well-being among female doctoral students in Sweden.

PubMed

Schmidt, Manuela; Umans, Timurs

2014-01-01

The aim of this study was to explore how female PhD students experience and perceive their well-being. Focus groups were conducted with female PhD students employed at a Swedish university. The study was performed using a phenomenological hermeneutic approach based on the concept of the lifeworld, used as both a philosophical perspective and a methodology. Three main themes emerged from the analysis: being true to oneself, being in the sphere of influence, and performing a balancing act. By unfolding these themes, the study shows that perceptions and experiences of well-being in female PhD students are a multifaceted phenomenon and materialize through interaction of different aspects of "self" (agent) and "others" (structure). As well as illustrating these perceptions and experiences, the study also presents female PhD students' conceptualization of their well-being, expressed in terms of a white-water rafting metaphor.

The H2 + + He proton transfer reaction: quantum reactive differential cross sections to be linked with future velocity mapping experiments

NASA Astrophysics Data System (ADS)

Hernández Vera, Mario; Wester, Roland; Gianturco, Francesco Antonio

2018-01-01

We construct the velocity map images of the proton transfer reaction between helium and molecular hydrogen ion {{{H}}}2+. We perform simulations of imaging experiments at one representative total collision energy taking into account the inherent aberrations of the velocity mapping in order to explore the feasibility of direct comparisons between theory and future experiments planned in our laboratory. The asymptotic angular distributions of the fragments in a 3D velocity space is determined from the quantum state-to-state differential reactive cross sections and reaction probabilities which are computed by using the time-independent coupled channel hyperspherical coordinate method. The calculations employ an earlier ab initio potential energy surface computed at the FCI/cc-pVQZ level of theory. The present simulations indicate that the planned experiments would be selective enough to differentiate between product distributions resulting from different initial internal states of the reactants.

Injection of a coaxial-gun-produced magnetized plasma into a background helicon plasma

NASA Astrophysics Data System (ADS)

Zhang, Yue; Lynn, Alan; Gilmore, Mark; Hsu, Scott

2014-10-01

A compact coaxial plasma gun is employed for experimental investigation of plasma bubble relaxation into a lower density background plasma. Experiments are being conducted in the linear device HelCat at UNM. The gun is powered by a 120-uF ignitron-switched capacitor bank, which is operated in a range of 5 to 10 kV and 100 kA. Multiple diagnostics are employed to investigate the plasma relaxation process. Magnetized argon plasma bubbles with velocities 1.2Cs, densities 1020 m-3 and electron temperature 13eV have been achieved. The background helicon plasma has density 1013 m-3, magnetic field from 200 to 500 Gauss and electron temperature 1eV. Several distinct operational regimes with qualitatively different dynamics are identified by fast CCD camera images. Additionally a B-dot probe array has been employed to measure the spatial toroidal and poloidal magnetic flux evolution to identify plasma bubble configurations. Experimental data and analysis will be presented.

Nursing entrepreneurship: motivators, strategies and possibilities for professional advancement and health system change.

PubMed

Wall, Sarah

2013-06-01

In Canada, as well as internationally, efficiency-focused organizational restructuring in healthcare has resulted in stressful job change for nurses, although nurses continue to work in a system that values technology-based, physician-provided services. Employed nurses have had to participate in organizational activities that undermine their professional values and goals. Nursing entrepreneurship presents an opportunity to explore nursing's professional potential in nursing practice that is uniquely independent. In this study, a focused ethnographic approach was used to explore the experiences of self-employed nurses, who see themselves as leaders in advancing the profession of nursing and its contribution to healthcare. Key themes in the findings include the responses of self-employed nurses to health system change, expanded roles for nurses, the consequences of this non-traditional approach to nursing work and the possibilities for change that arise from nursing entrepreneurship. This research has implications for healthcare policy, professional advocacy and nursing education. Copyright © 2013 Longwoods Publishing.

Reasoning and dyslexia: is visual memory a compensatory resource?

PubMed

Bacon, Alison M; Handley, Simon J

2014-11-01

Effective reasoning is fundamental to problem solving and achievement in education and employment. Protocol studies have previously suggested that people with dyslexia use reasoning strategies based on visual mental representations, whereas non-dyslexics use abstract verbal strategies. This research presents converging evidence from experimental and individual differences perspectives. In Experiment 1, dyslexic and non-dyslexic participants were similarly accurate on reasoning problems, but scores on a measure of visual memory ability only predicted reasoning accuracy for dyslexics. In Experiment 2, a secondary task loaded visual memory resources during concurrent reasoning. Dyslexics were significantly less accurate when reasoning under conditions of high memory load and showed reduced ability to subsequently recall the visual stimuli, suggesting that the memory and reasoning tasks were competing for the same visual cognitive resource. The results are consistent with an explanation based on limitations in the verbal and executive components of working memory in dyslexia and the use of compensatory visual strategies for reasoning. There are implications for cognitive activities that do not readily support visual thinking, whether in education, employment or less formal everyday settings.

Kim, Kyung Woo; Park, Sung Jin; Lim, Hae Sun; Cho, Hm Hak

2017-09-01

Safety climate and occupational stress are related with occupational accident. The present study tried to identify the differences in safety climate and occupational stress according to occupational accidents experience and employment type (e.g., direct workers and subcontract workers). In this study, we conducted a survey using safety climate scale and Korean Occupational Stress Scale and classified the participants into four groups: direct workers working for accident-free departments, direct workers working for accident departments, subcontract workers working for accident-free departments, and subcontract workers working for accident departments for 2 years within the same workplace in the shipbuilding industry. The direct workers and subcontract workers showed diverse results in subscales of safety climate and occupational stress. This result is supported by existing studies; however, further study is necessary for more supporting evidence and elaborative methodological approach. The necessity of management for safety climate and psychosocial factor such as occupational stress for both direct workers and subcontract workers as a whole is suggested by this study.

Decay uncovered in nonverbal short-term memory.

PubMed

Mercer, Tom; McKeown, Denis

2014-02-01

Decay theory posits that memory traces gradually fade away over the passage of time unless they are actively rehearsed. Much recent work exploring verbal short-term memory has challenged this theory, but there does appear to be evidence for trace decay in nonverbal auditory short-term memory. Numerous discrimination studies have reported a performance decline as the interval separating two tones is increased, consistent with a decay process. However, most of this tone comparison research can be explained in other ways, without reference to decay, and these alternative accounts were tested in the present study. In Experiment 1, signals were employed toward the end of extended retention intervals to ensure that listeners were alert to the presence and frequency content of the memoranda. In Experiment 2, a mask stimulus was employed in an attempt to distinguish between a highly detailed sensory trace and a longer-lasting short-term memory, and the distinctiveness of the stimuli was varied. Despite these precautions, slow-acting trace decay was observed. It therefore appears that the mere passage of time can lead to forgetting in some forms of short-term memory.

A new smooth robust control design for uncertain nonlinear systems with non-vanishing disturbances

NASA Astrophysics Data System (ADS)

Xian, Bin; Zhang, Yao

2016-06-01

In this paper, we consider the control problem for a general class of nonlinear system subjected to uncertain dynamics and non-varnishing disturbances. A smooth nonlinear control algorithm is presented to tackle these uncertainties and disturbances. The proposed control design employs the integral of a nonlinear sigmoid function to compensate the uncertain dynamics, and achieve a uniformly semi-global practical asymptotic stable tracking control of the system outputs. A novel Lyapunov-based stability analysis is employed to prove the convergence of the tracking errors and the stability of the closed-loop system. Numerical simulation results on a two-link robot manipulator are presented to illustrate the performance of the proposed control algorithm comparing with the layer-boundary sliding mode controller and the robust of integration of sign of error control design. Furthermore, real-time experiment results for the attitude control of a quadrotor helicopter are also included to confirm the effectiveness of the proposed algorithm.

The QBO and weak external forcing by solar activity: A three dimensional model study

NASA Technical Reports Server (NTRS)

Dameris, M.; Ebel, A.

1989-01-01

A better understanding is attempted of the physical mechanisms leading to significant correlations between oscillations in the lower and middle stratosphere and solar variability associated with the sun's rotation. A global 3-d mechanistic model of the middle atmosphere is employed to investigate the effects of minor artificially induced perturbations. The aim is to explore the physical mechanisms of the dynamical response especially of the stratosphere to weak external forcing as it may result from UV flux changes due to solar rotation. First results of numerical experiments dealing about the external forcing of the middle atmosphere by solar activity were presented elsewhere. Different numerical studies regarding the excitation and propagation of weak perturbations have been continued since then. The model calculations presented are made to investigate the influence of the quasi-biennial oscillation (QBO) on the dynamical response of the middle atmosphere to weak perturbations by employing different initial wind fields which represent the west and east phase of the QBO.
