Parent-child acculturation discrepancy is a risk factor in the development of children in immigrant families. Using a longitudinal sample of Chinese immigrant families, the current study examined how unsupportive parenting and parent-child sense of alienation sequentially mediate the relationship between parent-child acculturation discrepancy and child adjustment during early and middle adolescence. Acculturation discrepancy scores were created using multilevel modeling to take into account the interdependence among family members. Structural equation models showed that, during early adolescence, parent-child American orientation discrepancy is related to parents’ use of unsupportive parenting practices; parents’ use of unsupportive parenting is related to increased sense of alienation between parents and children, which in turn is related to more depressive symptoms and lower academic performance in Chinese American adolescents. These patterns of negative adjustment established in early adolescence persist into middle adolescence. This mediating effect is more apparent among father-adolescent dyads than among mother-adolescent dyads. In contrast, parent-child Chinese orientation discrepancy does not demonstrate a significant direct or indirect effect on adolescent adjustment, either concurrently or longitudinally. The current findings suggest that early adolescence is more susceptible to the negative effects of parent-child acculturation discrepancy; they also underscore the importance of fathering in Chinese immigrant families.

Parents wish to reduce their child's pain during medical procedures but may not know how to do so. We systematically reviewed the literature on parents' experiences and information needs related to managing their child's pain for common medical procedures. Of 2678 records retrieved through database searching, 5 were included. Three additional records were identified by scanning reference lists. Five studies were qualitative, and 3 were quantitative. Most took place in North America or Europe (n = 7) and described neonatal intensive care unit experiences (n = 5). Procedures included needle-related medical procedures (eg, venipuncture, phlebotomy, intravenous insertion), sutures, and wound repair and treatment, among others. Generally, parents desired being present during procedures, wanted to remain stoic for their child, and thought that information would be empowering and relieve stress but felt unsupported in taking an active role. Supporting and educating parents may empower them to lessen pain for their children while undergoing medical procedures.

As the lead author of a recently published systematic review on hydrogel burn dressings in pre-hospital, I was alarmed to read the claim by the authors to the effect no one method of burn wound cooling was superior to any other; "There is no evidence to recommend a specific temperature or method of cooling". The reputation and prominence of the ERC within the circle of resuscitation councils now delving into 1st Aid recommendations leads to the conclusion that misguided recommendations may cause confusion amongst first responders, may falsely misdirect 1st Aid providers to unsupported practices or alternatively create a window of opportunity for marketers or sellers of alternative burn 1st Aid technologies to make unsupported claims in respect of comparable efficacy of their own product versus "traditional" methods.

Unsupportive social interactions and affective states: examining associations of two oxytocin-related polymorphisms.

McInnis, Opal A; McQuaid, Robyn J; Matheson, Kimberly; Anisman, Hymie

2017-01-01

Two single-nucleotide polymorphisms (SNPs) on oxytocin-related genes, specifically the oxytocin receptor (OXTR) rs53576 and the CD38 rs3796863 variants, have been associated with alterations in prosocial behaviors. A cross-sectional study was conducted among undergraduate students (N = 476) to examine associations between the OXTR and CD38 polymorphisms and unsupportive social interactions and mood states. Results revealed no association between perceived levels of unsupportive social interactions and the OXTR polymorphism. However, A carriers of the CD38 polymorphism, a variant previously associated with elevated oxytocin, reported greater perceived peer unsupportive interactions compared to CC carriers. As expected, perceived unsupportive interactions from peers was associated with greater negative affect, which was moderated by the CD38 polymorphism. Specifically, this relation was stronger among CC carriers of the CD38 polymorphism (a variant thought to be linked to lower oxytocin). When examining whether the OXTR polymorphism moderated the relation between unsupportive social interactions from peers and negative affect there was a trend toward significance, however, this did not withstand multiple testing corrections. These findings are consistent with the perspective that a variant on an oxytocin polymorphism that may be tied to lower oxytocin is related to poor mood outcomes in association with negative social interactions. At the same time, having a genetic constitution presumed to be associated with higher oxytocin was related to increased perceptions of unsupportive social interactions. These seemingly paradoxical findings could be related to previous reports in which variants associated with prosocial behaviors were also tied to relatively more effective coping styles to deal with challenges.

To investigate the proportion of documented ultrasound findings that were unsupported by stored ultrasound images in the obstetric ultrasound unit, before and after the implementation of a quality improvement process consisting of a checklist and feedback. A quality improvement process was created involving utilization of a checklist and feedback from physician to sonographer. The feedback was based on findings of the physician's review of the report and images using a check list. To assess the impact of this process, two groups were compared. Group 1 consisted of 58 ultrasound reports created prior to initiation of the process. Group 2 included 65 ultrasound reports created after process implementation. Each chart was reviewed by a physician and a sonographer. Findings considered unsupported by stored images by both reviewers were used for analysis, and the proportion of unsupported findings was compared between the two groups. Results are expressed as mean ± standard error. A p value of < .05 was used to determine statistical significance. Univariate analysis of baseline characteristics and potential confounders showed no statistically significant difference between the groups. The mean proportion of unsupported findings in Group 1 was 5.1 ± 0.87, with Group 2 having a significantly lower proportion (2.6 ± 0.62) (p value = .018). Results suggest a significant decrease in the proportion of unsupported findings in ultrasound reports after quality improvement process implementation. Thus, we present a simple yet effective quality improvement process to reduce unsupported ultrasound findings.

Discrepancies between patients' and partners' perceptions of unsupportive behavior in chronic obstructive pulmonary disease.

The literature on chronic diseases indicates that partner support, as perceived by patients, contributes to well-being of patients in either a positive or a negative way. Previous studies indicated that patients' and partners' perceptions of unsupportive partner behavior are only moderately related. Our aim was (1) to investigate whether discrepancies between patients' and partners' perceptions of two types of unsupportive partner behavior-overprotection and protective buffering-were associated with the level of distress reported by patients with chronic obstructive pulmonary disease (COPD) and (2) to evaluate whether the direction of the differences between patients' and partners' perceptions was associated with distress (i.e., whether patient distress was associated with greater patient or greater partner reports of unsupportive partner behavior). A cross-sectional study was performed using the data of a sample of 68 COPD patients and their spouses. Distress was assessed using the Hopkins Symptom Checklist-25. Patients' and partners' perceptions of unsupportive partner behavior were assessed with a questionnaire measuring overprotection and protective buffering. Distress was independently associated with patients' perceptions of protective buffering and discrepancies in spouses' perceptions of overprotection. Regarding the direction of the discrepancy, we found that greater partner reports of overprotection as compared with patient reports were related to more distress in COPD patients. Our study showed that patients' distress was associated not only with patients' perceptions, but also with discrepancies between patients' and partners' perceptions of unsupportive partner behavior.

The aim of this study is to analyze a set of socializing agents for sport and physical activities and to establish their relationship with leisure time sport and physical activities behaviors and practice patterns in samples of teenage students with different sociocultural backgrounds. The sample included 2168 students in their first year of secondary education, 423 of them being from Costa Rica, 408 from Mexico, and 1337 from Spain (1052 male students, 1037 female students, and 79 students who did not specify gender) aged 11-16 years old ( M = 12.49; SD = .81). A validated questionnaire with questions about leisure time sport and physical activities and socializing agents was used. Descriptive, inferential, and multinomial logistic regression analyses were carried out with SPSS 17.0 to compare all three countries. Costa Rica had the most active students, best friends' inactivity, and unsupportive parents being the agents predicting inactivity and a low level of sport and physical activities. Mexico has a high dropout rate and inactive students exceed active ones; no agent predicts inactivity or sport and physical activities pattern. Spain has the highest level of sport and physical activities practice, and parents, siblings, and friends are predicting agents of inactivity together with unsupportive parents and friends.

Unsupportive parenting moderates the effects of family psychosocial intervention on metabolic syndrome in African American youth.

Family relationships have been linked to obesity and related disorders in youth, but few studies have provided causal evidence of this association. This study tested the impact of a family psychosocial intervention on components of metabolic syndrome-a condition driven largely by abdominal obesity-in African American youth. In particular, the study tested whether effects were strongest among those who started at highest risk, that is, with high levels of unsupportive parenting at baseline. Randomized clinical trial of a community sample of 391 African American youth (mean age=11.2 years) conducted in 2001-2002, with follow-up metabolic syndrome assessment in 2014-2015. Participants were assigned either to receive a weekly family intervention or to a control group. The primary study outcome was the number of components of metabolic syndrome that were clinically elevated at age 25, including central adiposity, blood pressure, triglycerides, glucose and low high-density lipoproteins. Unsupportive parenting was measured by questionnaires at baseline. Significant interaction effects were found between group assignment and baseline unsupportive parenting on counts of metabolic syndrome components in youth (beta=-0.17, P=0.03). Among those who started with higher levels of unsupportive parenting at age 11, participation in the family intervention reduced the number of clinically elevated components of the metabolic syndrome at age 25 relative to the control group. No such effect was seen among those who started with good parenting. Mediation analyses suggested that changes in the psychosocial targets of the parenting intervention partially accounted for the effects amongst those high in unsupportive parenting at baseline (effect size=-0.350, s.e.=0.178). These findings suggest that efforts to improve family relationships may be able to ameliorate the detrimental effects that harsh and unsupportive parenting have on obesity-related outcomes such as metabolic syndrome in youth.

Little attention has been paid to the role of holding back sharing concerns in the psychological adaptation of women newly diagnosed with gynecological cancers. The goal of the present study was to evaluate the role of holding back concerns in psychosocial adjustment and quality of life, as well as a possible moderating role for emotional expressivity and perceived unsupportive responses from family and friends. Two hundred forty-four women diagnosed with gynecological cancer in the past 8 months completed measures of holding back, dispositional emotional expressivity, perceived unsupportive responses from family and friends, cancer-specific distress, depressive symptoms and quality of life. Emotional expressivity moderated the association between holding back and cancer-specific distress and quality of life, but not depressive symptoms. Greater holding back was more strongly associated with higher levels of cancer-related distress among women who were more emotionally expressive than among women who were less expressive. Perceived unsupportive responses did not moderate the associations between holding back and psychosocial outcomes. Holding back sharing concerns was more common in this patient population than other cancer populations. Dispositional expressivity played a role in how harmful holding back concerns was for women, while unsupportive responses from family and friends did not. © 2014.

Molecular dynamics simulations of ejecta production from sinusoidal tin surfaces under supported and unsupported shocks

2018-04-01

Micro-ejecta, an instability growth process, occurs at metal/vacuum or metal/gas interface when compressed shock wave releases from the free surface that contains surface defects. We present molecular dynamics (MD) simulations to investigate the ejecta production from tin surface shocked by supported and unsupported waves with pressures ranging from 8.5 to 60.8 GPa. It is found that the loading waveforms have little effect on spike velocity while remarkably affect the bubble velocity. The bubble velocity of unsupported shock loading remains nonzero constant value at late time as observed in experiments. Besides, the time evolution of ejected mass in the simulations is compared with the recently developed ejecta source model, indicating the suppressed ejection of unmelted or partial melted materials. Moreover, different reference positions are chosen to characterize the amount of ejecta under different loading waveforms. Compared with supported shock case, the ejected mass of unsupported shock case saturates at lower pressure. Through the analysis on unloading path, we find that the temperature of tin sample increases quickly from tensile stress state to zero pressure state, resulting in the melting of bulk tin under decaying shock. Thus, the unsupported wave loading exhibits a lower threshold pressure causing the solid-liquid phase transition on shock release than the supported shock loading.

On the effect of unsupported sleepers on the dynamic behaviour of a railway track

Zhu, J. Y.; Thompson, D. J.; Jones, C. J. C.

2011-09-01

The effect of unsupported sleepers on the dynamic behaviour of a railway track is studied based on vehicle-track dynamic interaction theory, using a model of the track as a Timoshenko beam supported on a periodic elastic foundation. Considering the vehicle's running speed and the number of unsupported sleepers, the track dynamic characteristics are investigated and verified in the time and frequency domains by experiments on a 1:5 scale model wheel-rail test rig. The results show that when hanging sleepers are present, leading to a discontinuous and irregular track support, additional wheel-rail interaction forces are generated. These forces increase as further sleepers become unsupported and as the vehicle's running speed increases. The adjacent supports experience increased dynamic forces which will lead to further deterioration of track quality and the formation of long wavelength track irregularities, which worsen the vehicles' running stability and riding comfort. Stationary transfer functions measurements of the dynamic behaviour of the track are also presented to support the findings.

Combustion of Unconfined Droplet Clusters in Microgravity

NASA Technical Reports Server (NTRS)

Ruff, G. A.; Liu, S.

2001-01-01

Combustion experiments using arrays of droplets seek to provide a link between single droplet combustion phenomena and the behavior of complex spray combustion systems. Both single droplet and droplet array studies have been conducted in microgravity to better isolate the droplet interaction phenomena and eliminate or reduce the confounding effects of buoyancy-induced convection. In most experiments involving droplet arrays, the droplets are supported on fibers to keep them stationary and close together before the combustion event. The presence of the fiber, however, disturbs the combustion process by introducing a source of heat transfer and asymmetry into the configuration. As the number of drops in a droplet array increases, supporting the drops on fibers becomes less practical because of the cumulative effect of the fibers on the combustion process. To eliminate the effect of the fiber, several researchers have conducted microgravity experiments using unsupported droplets. Jackson and Avedisian investigated single, unsupported drops while Nomura et al. studied droplet clouds formed by a condensation technique. The overall objective of this research is to extend the study of unsupported drops by investigating the combustion of well-characterized drop clusters in a microgravity environment. Direct experimental observations and measurements of the combustion of droplet clusters would fill a large gap in our current understanding of droplet and spray combustion and provide unique experimental data for the verification and improvement of spray combustion models. In this work, the formation of drop clusters is precisely controlled using an acoustic levitation system so that dilute, as well as dense clusters can be created and stabilized before combustion in microgravity is begun. This paper describes the design and performance of the 1-g experimental apparatus, some preliminary 1-g results, and plans for testing in microgravity.

The activities of unsupported (210)Pb, a naturally occurring radionuclide, were measured in samples of soil and terrestrial mosses collected in Serbia. Considering that clay particles in soil have a high affinity for Pb adsorption, and that mosses usually capture aerosol particles to obtain necessary nutrients, measurable amounts of airborne (210)Pb, the daughter of (222)Rn, can be registered in both soil and mosses. The objective of the present study was to determine if it is possible to compare the activity of unsupported (210)Pb in soil and moss collected at the same sampling site, and to establish if a correlation exists between these measured values.

Griffin, B; Woo, P; Colton, R; Casper, J; Brewer, D

1995-03-01

The purpose of this study was to develop a definition of the supported singing voice based on physiological characteristics by comparing the subjects' concepts of a supported voice with objective measurements of their supported and unsupported voice. This preliminary report presents findings based on data from eight classically trained singers. Subjects answered questions about their concepts of the characteristics of the supported singing voice and how it is produced. Samples of the supported and unsupported singing voice produced at low, medium, and high pitches at a comfortable loudness level were collected for acoustic, spectral, airflow, electroglottographic, air volume, and stroboscopic analyses. Significant differences between the supported and unsupported voice were found for sound pressure level (SPL), peak airflow, subglottal pressure (Ps), glottal open time, and frequency of the fourth formant (F4). Mean flow and F2 frequency differences were sex and pitch related. Males adjusted laryngeal configuration to produce supported voice, whereas glottal configuration differences were greater in females. Breathing patterns were variable and not significantly different between supported and unsupported voice. Subjects in this study believe that the supported singing voice is resonant, clear, and easy to manage and is produced by correct breath management. Results of data analysis show that the supported singing voice has different spectral characteristics from and higher SPL, peak airflow, and Ps than the unsupported voice. Singers adjust laryngeal and/or glottal configuration to account for these changes, but no significant differences in breathing activity were found.

Brachial plexopathy is not uncommon after shoulder surgery. Although thought to be due to stretch neuropathy, its etiology is poorly understood. This study aimed to identify arm positions and maneuvers that may risk causing brachial plexopathy during shoulder arthroplasty. Tensions in the cords of the brachial plexuses of 6 human cadaveric upper limbs were measured using load cells while each limb was placed in different arm positions and while they underwent shoulder hemiarthroplasty and revision reverse arthroplasty. Arthroplasty procedures in 4 specimens were performed with standard limb positioning (unsupported), and 2 specimens were supported from under the elbow (supported). Each cord then underwent biomechanical testing to identify tension corresponding to 10% strain (the stretch neuropathy threshold in animal models). Tensions exceeding 15 N, 11 N, and 9 N in the lateral, medial, and posterior cords, respectively, produced 10% strain. Shoulder abduction >70° and combined external rotation >60° with extension >50° increased medial cord tension above the 10% strain threshold. Medial cord tensions (mean ± standard error of the mean) in unsupported specimens increased over baseline during hemiarthroplasty (sounder insertion [4.7 ± 0.6 N, P = .04], prosthesis impaction [6.1 ± 0.8 N, P = .04], and arthroplasty reduction [5.0 ± 0.7 N, P = .04]) and revision reverse arthroplasty (retractor positioning [7.2 ± 0.8 N, P = .02]). Supported specimens experienced lower tensions than unsupported specimens. Shoulder abduction >70°, combined external rotation >60° with extension >50°, and downward forces on the humeral shaft may risk causing brachial plexopathy. Retractor placement, sounder insertion, humeral prosthesis impaction, and arthroplasty reduction increase medial cord tensions during shoulder arthroplasty. Supporting the arm from under the elbow protected the brachial plexus in this cadaveric model. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

To examine a video-based learning activity for engaging physiotherapy students in preparation for practical examinations and determine student performance outcomes. Multi-method employing qualitative and quantitative data collection procedures. Tertiary education facility on the Gold Coast, Queensland, Australia. Physiotherapy students in their first year of a two-year graduate entry program. Questionnaire-based surveys and focus groups were used to examine student perceptions and satisfaction. Surveys were analysed based on the frequency of responses to closed questions made on a 5-pont Likert scale, while a thematic analysis was performed on focus group transcripts. t-Tests were used to compare student awarded marks and examiner awarded marks and evaluate student performance. Sixty-two physiotherapy students participated in the study. Mean response rate for questionnaires was 93% and eight students (13%) participated in the focus group. Participants found the video resources effective to support their learning (98% positive) and rating the video examples to be an effective learning activity (96% positive). Themes emergent from focus group responses were around improved understanding, reduced performance anxiety, and enjoyment. Students were, however, critical of the predictable nature of the example performances. Students in the current cohort supported by the video-based preparation activity exhibited greater practical examination marks than those from the previous year who were unsupported by the activity (mean 81.6 SD 8.7 vs. mean 78.1 SD 9.0, p=0.01). A video-based learning activity was effective for preparing physiotherapy students for practical examinations and conferred benefits of reduced anxiety and improved performance.

FY1 doctors' ethicolegal challenges in their first year of clinical practice: an interview study.

PubMed

Vivekananda-Schmidt, Pirashanthie; Vernon, Bryan

2014-04-01

There is little evidence of junior trainee perspectives in the design and implementation of medical ethics and law (MEL) curriculum in UK medical schools. To determine the ethical issues the foundation year 1 (FY1) doctors (first year after graduation)  encountered during clinical practice and the skills and knowledge of MEL, which were useful in informing MEL curriculum development. The National Research Ethics Service gave ethical approval. Eighteen one-to-one interviews were conducted in each school with FY1 doctors. Interviews were recorded and transcribed verbatim; a thematic analysis was undertaken with the transcriptions and saturation of themes was achieved. Themes closely overlapped between the two study sites. (1) Knowing my place as an FY1 (this theme consisted of four subthemes: challenging the hierarchy, being honest when the team is titrating the truth, taking consent for unfamiliar procedures and personal safety vs competing considerations); (2) Do not attempt resuscitation)/end-of-life pathway and its implications; (3) 'You have to be there' (contextualising ethics and law teaching through cases or role plays to allow students to explore future work situations); and (4) advanced interpersonal skills competency for ethical clinical practice. The data provide a snapshot of the real challenges faced by MEL FY1 doctors in early clinical practice: they may feel ill-prepared and sometimes unsupported by senior members of the team. The key themes suggest areas for development of undergraduate and postgraduate MEL curricula. We will work to develop our own curriculum accordingly. We intend to further investigate the applicability of our findings to UK medical ethics and law curriculum.

A family of diruthenium complexes with ligand-unsupported Ru-Ru bonds has been systematically synthesized, and their crystal structures and physical properties have been examined. A simple, useful reaction between Ru2(OAc)4Cl (OAc- = acetate) and catechol derivatives in the presence of bases afforded a variety of diruthenium complexes, generally formulated as [Na(n){Ru2(R4Cat)4}] (n = 2 or 3; R4 = -F4, -Cl4, -Br4, -H4, -3,5-di-t-Bu, and -3,6-di-t-Bu; Cat(2-) = catecholate). The most characteristic feature of the complexes is the formation of short ligand-unsupported Ru-Ru bonds (2.140-2.273 A). These comprehensive studies were carried out to evaluate the effects of the oxidation states and the substituents governing the molecular structures and physicochemical properties. The Ru-Ru bond distances, rotational conformations, and bending structures of the complexes were successfully varied. The results presented in this manuscript clearly demonstrate that the complexes with ligand-unsupported Ru-Ru bonds can sensitively respond to redox reactions and ligand substituents on the basis of the greater degree of freedom in their molecular structures.

We investigated whether 2 types of personalized health guidance (repeated and single counseling) in the Japanese nationwide cardiovascular prevention system promoted smoking cessation among smokers. The study included 47,745 Japanese smokers aged 40 to 74 years classified into 2 personalized health guidance schemes. After a 1-year follow-up, we compared the rates of smoking cessation between individuals who had received counseling ("supported") and those who had not received counseling ("unsupported"). Using propensity score matching analysis, we estimated the average treatment effect (ATE) of each approach on smoking cessation after balancing out the characteristics between the supported and unsupported groups. The propensity score regression model included age, medical insurance type, weight gain since the age of 20 years, exercise, eating habits, alcohol intake, quality of sleep, readiness to modify lifestyle, willingness to receive support, and body mass index. In the repeated counseling scheme, the age-adjusted rates of smoking cessation in the supported and unsupported groups were 8.8% and 6.3% for males, and 9.8% and 9.1% for females respectively. In the single counseling scheme, the corresponding rates were 8.4% and 7.3% for supported and unsupported males, and 11.0% and 11.7% for supported and unsupported females respectively. The ATE of repeated counseling was ＋2.64% (95% confidence interval: ＋1.51% to ＋3.77%) for males and ＋3.11% (－1.85% to ＋8.07%) for females. The ATE of single counseling was ＋0.61% (－1.17% to ＋2.38%) for males and －1.06% (－5.96% to ＋3.85%) for females. In the Japanese cardiovascular prevention system, repeated counseling may promote smoking cessation among male smokers.

BACKGROUND Many beliefs about obesity persist in the absence of supporting scientific evidence (presumptions); some persist despite contradicting evidence (myths). The promulgation of unsupported beliefs may yield poorly informed policy decisions, inaccurate clinical and public health recommendations, and an unproductive allocation of research resources and may divert attention away from useful, evidence-based information. METHODS Using Internet searches of popular media and scientific literature, we identified, reviewed, and classified obesity-related myths and presumptions. We also examined facts that are well supported by evidence, with an emphasis on those that have practical implications for public health, policy, or clinical recommendations. RESULTS We identified seven obesity-related myths concerning the effects of small sustained increases in energy intake or expenditure, establishment of realistic goals for weight loss, rapid weight loss, weight-loss readiness, physical-education classes, breast-feeding, and energy expended during sexual activity. We also identified six presumptions about the purported effects of regularly eating breakfast, early childhood experiences, eating fruits and vegetables, weight cycling, snacking, and the built (i.e., human-made) environment. Finally, we identified nine evidence-supported facts that are relevant for the formulation of sound public health, policy, or clinical recommendations. CONCLUSIONS False and scientifically unsupported beliefs about obesity are pervasive in both scientific literature and the popular press. (Funded by the National Institutes of Health.) PMID:23363498

Graduate-Assistant Athletic Trainers' Perceptions of Professional Socialization in the Collegiate Setting: Part I

Thrasher, Ashley B.; Walker, Stacy E.; Hankemeier, Dorice A.; Mulvihill, Thalia

Context: Many newly credentialed athletic trainers (ATs) pursue graduate assistantships, which allow them to gain experience while being supervised by an experienced AT. The graduate-assistant (GA) ATs' perception of their socialization process into the collegiate setting is unknown. Objective: To explore the professional socialization of GAs in the collegiate setting. Design: Qualitative study. Setting: Phone interviews. Patients or Other Participants: A total of 19 collegiate GAs (15 women, 4 men; average age = 23 ± 0.15 years; National Collegiate Athletic Association Division I = 13, II = 3, III = 2; National Association of Intercollegiate Athletics = 2; postprofessional athletic training program = 6) participated. Data Collection and Analysis: Data were collected via phone interviews and transcribed verbatim. Interviews were conducted until data saturation occurred. Data were analyzed through phenomenologic reduction. Trustworthiness was established via member checks and peer review. Results: Four themes emerged: (1) role identity, (2) initial entry into role, (3) maturation, and (4) success. Before beginning their role, participants envisioned the assistantship as a way to gain independent experience while being mentored. They perceived themselves as the primary care providers for their athletic teams. Those who were immediately immersed into clinical practice adapted to their role quickly despite experiencing stress initially. Participants felt that a formal orientation process and a policies and procedures manual would have alleviated some of the initial stress. The GAs matured as they practiced clinically and developed confidence as they gained experience. Personal attributes, experience, and peer and supervisor support contributed to perceived success as GAs. Factors that hindered perceived success were lack of confidence, an unsupportive environment, and long hours. Conclusions: When looking for graduate assistantships, ATs should seek a position that allows them to practice independently and provides didactic educational opportunities while aligning with their athletic training philosophies.

2000-06-01

There has recently been an explosion of theoretical literature on social space. A central claim in this literature is that postmodern spaces are experienced as confusing or disorienting by human subjects. This claim remains untested. The paper reports results from a small-scale survey conducted in one form of postmodern space--the shopping mall. It suggests that unsupported assertions about the disorienting effects of postmodern space and their associated influence on consumerist activities should be treated with scepticism. Through practice humans are able to develop routines which enable them to competently navigate these spaces.

The penumbra of thalidomide, the litigation culture and the licensing of pharmaceuticals

PubMed Central

2012-01-01

Fifty years ago several thousand children were born with severe limb defects after their mothers had been given thalidomide in pregnancy. This tragedy caused procedures for licensing new medicines to become much stricter. Where, nevertheless, significant side effects were found it became common to sue for damages. These consequences have caused possibly an even greater disaster damaging many more people and threatening ruin to health services everywhere. The huge increase in both time and cost in bringing medicines to market is increasing their price to unsupportable levels; and only wealthy companies are now able to do so. This requires reform as does litigation for ‘statistical’ harmful effects. PMID:22908318

Stiffness and strength of fiber reinforced polymer composite bridge deck systems

NASA Astrophysics Data System (ADS)

Zhou, Aixi

This research investigates two principal characteristics that are of primary importance in Fiber Reinforced Polymer (FRP) bridge deck applications: STIFFNESS and STRENGTH. The research was undertaken by investigating the stiffness and strength characteristics of the multi-cellular FRP bridge deck systems consisting of pultruded FRP shapes. A systematic analysis procedure was developed for the stiffness analysis of multi-cellular FRP deck systems. This procedure uses the Method of Elastic Equivalence to model the cellular deck as an equivalent orthotropic plate. The procedure provides a practical method to predict the equivalent orthotropic plate properties of cellular FRP decks. Analytical solutions for the bending analysis of single span decks were developed using classical laminated plate theory. The analysis procedures can be extended to analyze continuous FRP decks. It can also be further developed using higher order plate theories. Several failure modes of the cellular FRP deck systems were recorded and analyzed through laboratory and field tests and Finite Element Analysis (FEA). Two schemes of loading patches were used in the laboratory test: a steel patch made according to the ASSHTO's bridge testing specifications; and a tire patch made from a real truck tire reinforced with silicon rubber. The tire patch was specially designed to simulate service loading conditions by modifying real contact loading from a tire. Our research shows that the effects of the stiffness and contact conditions of loading patches are significant in the stiffness and strength testing of FRP decks. Due to the localization of load, a simulated tire patch yields larger deflection than the steel patch under the same loading level. The tire patch produces significantly different failure compared to the steel patch: a local bending mode with less damage for the tire patch; and a local punching-shear mode for the steel patch. A deck failure function method is proposed for predicting the failure of FRP decks. Using developed laminated composite theories and FEA techniques, a strength analysis procedure containing ply-level information was proposed and detailed for FRP deck systems. The behavior of the deck's unsupported (free) edges was also investigated using ply-level FEA.

A real-time analysis of parent-child emotion discussions: the interaction is reciprocal.

The current study examined reciprocal parent-child emotion-related behaviors and links to child emotional and psychological functioning. Fifty-four mothers, fathers, and children (7 to 12 years old) participated in four emotion discussions about a time when the child felt angry, happy, sad, and anxious. Supportive emotion parenting (SEP), unsupportive emotion parenting (UEP), and child adaptive/maladaptive emotion regulation (ER) behaviors were coded using Noldus behavioral research software (Noldus Information Technology, 2007). Parents were more likely to follow children's adaptive emotion regulation with supportive versus unsupportive emotional responses and children were more likely to show adaptive versus maladaptive emotion regulation in response to supportive emotion parenting. Interaction patterns involving unsupportive emotion parenting related to child psychological and emotional outcomes. The results provide empirical support for an evocative person-environment framework of emotion socialization and identify the ways in which particular patterns of interaction relate to psychological functioning in youth.

A qualitative approach was used to explore workplace experiences of nurses who have a mental illness. Interview transcripts from 29 nurses in New South Wales, Australia were subjected to discourse analysis. One significant finding was a theme depicting the need for support and trust. This superordinate theme encompassed four subelements: declaring mental illnesses, collegial support, managerial support, and enhancing support. Most of the participants portrayed their workplace as an unsupportive and negative environment. A number of colleagues were depicted as having little regard for the codes for professional nursing practice. This paper shows how nurses in the study dealt with the workplace support associated with mental illness.

Using a personal social network framework, this qualitative study sought to understand how women in substance abuse treatment describe their network members' supportive and unsupportive behaviors related to recovery. Eighty-six women were interviewed from residential and outpatient substance abuse treatment programs. Positive and negative aspects of women's social networks were assessed via open-ended questions. Analysis was guided by grounded theory techniques using three coders. The findings extend classic social support concepts such as emotional, tangible, and informational support. Practice implications are presented in light of the potential roles network members may play in substance use and recovery. PMID:20953326

"The right help at the right time": Positive constructions of peer and professional support for breastfeeding.

PubMed

Burns, Elaine; Schmied, Virginia

Support during the early establishment phase of breastfeeding is important but women report that health professionals can undermine their confidence with breastfeeding. Breastfeeding support provided in fragmented hospital based models of care predominantly reflect authoritative expert advice-giving which women describe as conflicting and unsupportive. Women show a preference for support from a known midwife, or a peer supporter, or a combination of the two. Peer support counsellors and privately practicing midwives approached breastfeeding support in a similar way. They interacted with women as a ‘knowledgeable friend’ and normalised breastfeeding challenges which enhanced women’s confidence with breastfeeding.

Apparatus and method for suppressing vibration and displacement of a bellows

DOEpatents

Kuklo, T.C.

1984-01-01

Flexible bellows are utilized between two systems, such as a pumping system and a process station, to partially absorb system vibrations and to compensate for misalignment between the systems. It is common practice to either clamp a rigid spacer between flanges of the two systems to separate them from each other, or to maintain the bellows in unsupported relationship between these systems. In the former bellows arrangement, the rigid spacer transmits vibratory energy between the two systems and the bellows tends to function as an undamped or underdamped unit that resonates at its own frequency to create additional vibratory energy, transmitted to the systems. In the latter, unsupported bellows arrangement, the pressure differential prevalent between the fluid flowing through the bellows and ambient normally causes extension or retraction of the bellows and resulting misalignment problems. The present invention substantially solves the above vibration and misalignment problems by providing an inflatable tube in surrounding relationship about a bellows to suppress vibration and displacement thereof. A method for isolating first and second systems from each other to prevent the transmission of vibratory energy therebetween comprises the steps of attaching at least one flexible bellows between the systems, surrounding the bellows with an inflatable tube, and maintaining a predetermined pressure in the tube to urge the tube in flexible contact with at least some of the convolutions of the bellows.

Understanding the context of novel interventions for self-injurious thoughts and behaviors: A reply to Nielsen et al.

PubMed

Franklin, Joseph C; Fox, Kathryn R; Ribeiro, Jessica D; Nock, Matthew K

2017-08-01

In this response to the commentary by Nielsen, Kirtley, & Townsend (in press), the authors note several points of agreement related to further testing of therapeutic evaluative conditioning (TEC) for self-injurious thoughts and behaviors (SITBs), navigating logistical and ethical issues surrounding mobile interventions, and integrating such interventions into traditional practice. They also note a common mission held by Nielsen et al., themselves, and the SITB research community more broadly: the large-scale reduction of SITBs. Given that national rates of SITBs have never declined appreciably and have been on the rise in recent decades, there is an urgent need for progress toward this goal. However, they also highlight several unsupported or inaccurate assumptions and specific points made by Nielsen et al. that are important to correct for the sake of accuracy and progress in the prediction and prevention of SITBs. These include an overly narrow conceptualization of what constitutes an intervention; an unsupported model of the causes of SITBs and how to best prevent them; an erroneous belief about the iatrogenic effects of SITB stimulus exposure; and inaccuracies in their description of the development, testing, and release of TEC. The authors hope that this brief discussion of the evidence will facilitate progress toward the mission of large-scale reductions in SITBs.

Recommendations to support the back and feet during blood pressure (BP) measurement are not always followed in clinical practice. Our objective was to determine to what extent back and feet support affects mean oscillometric BP measurements. Eighty-five consecutive, consenting participants 18 years or older with systolic BP readings 80-220 mmHg and diastolic BP readings 50-120 mmHg and arm circumferences of 25-43 cm were recruited. BP was measured using an Omron HEM 907 oscillometric device. Back and feet support were examined independently. First, while the feet were supported, two sets of three BP readings were taken in random order: one with the back supported and one with the back unsupported. Next, with the back supported, two sets of three BP readings were taken in random order: one with the feet dangling and one with feet supported. The mean age of the participants was 52.0±20.7 years and the mean arm circumference was 31.0±3.2 cm; 62% were women and 49% had hypertension. The mean BP levels with the back unsupported were slightly higher than those with the back supported (119.8±15.5/69.9±8.9 vs. 119.2±16.4/68.2±8.8 mmHg; difference of 0.7±4.9/1.8±3.0; P=0.21 for systolic and <0.0001 for diastolic comparisons). The mean BP levels with feet dangling were slightly lower than with feet supported (120.3±16.3/72.6±8.9 vs. 121.2±16.1/72.9±8.6 mmHg; difference of -0.9±4.1/-0.3±2.8; P=0.04 for systolic and <0.36 for diastolic comparisons). Systolic BP differences were greater than or equal to 5 mmHg in 34% (back phase) and 23% (feet phase) of the participants. Provision of back and feet support has a small effect on the mean oscillometric BP. The magnitude of effect is greatest on diastolic BP when the back is unsupported.

Droplet Vaporization In A Levitating Acoustic Field

Combustion experiments using arrays of droplets seek to provide a link between single droplet combustion phenomena and the behavior of complex spray combustion systems. Both single droplet and droplet array studies have been conducted in microgravity to better isolate the droplet interaction phenomena and eliminate or reduce the effects of buoyancy-induced convection. In most experiments involving droplet arrays, the droplets are supported on fibers to keep them stationary and close together before the combustion event. The presence of the fiber, however, disturbs the combustion process by introducing a source of heat transfer and asymmetry into the configuration. As the number of drops in a droplet array increases, supporting the drops on fibers becomes less practical because of the cumulative effect of the fibers on the combustion process. To eliminate the effect of the fiber, several researchers have conducted microgravity experiments using unsupported droplets. Jackson and Avedisian investigated single, unsupported drops while Nomura et al. studied droplet clouds formed by a condensation technique. The overall objective of this research is to extend the study of unsupported drops by investigating the combustion of well-characterized drop clusters in a microgravity environment. Direct experimental observations and measurements of the combustion of droplet clusters would provide unique experimental data for the verification and improvement of spray combustion models. In this work, the formation of drop clusters is precisely controlled using an acoustic levitation system so that dilute, as well as dense clusters can be created and stabilized before combustion in microgravity is begun. While the low-gravity test facility is being completed, tests have been conducted in 1-g to characterize the effect of the acoustic field on the vaporization of single and multiple droplets. This is important because in the combustion experiment, the droplets will be formed and levitated prior to ignition. Therefore, the droplets will begin to vaporize in the acoustic field thus forming the "initial conditions" for the combustion process. Understanding droplet vaporization in the acoustic field of this levitator is a necessary step that will help to interpret the experimental results obtained in low-gravity.

The construction of EBMPracticeNet, a national electronic point-of-care information platform in Belgium, began in 2011 to optimize quality of care by promoting evidence-based decision making. The project involved, among other tasks, the translation of 940 EBM Guidelines of Duodecim Medical Publications from English into Dutch and French. Considering the scale of the translation process, it was decided to make use of computer-aided translation performed by certificated translators with limited expertise in medical translation. Our consortium used a hybrid approach, involving a human translator supported by a translation memory (using SDL Trados Studio), terminology recognition (using SDL MultiTerm terminology databases) from medical terminology databases, and support from online machine translation. This resulted in a validated translation memory, which is now in use for the translation of new and updated guidelines. The objective of this experiment was to evaluate the performance of the hybrid human and computer-assisted approach in comparison with translation unsupported by translation memory and terminology recognition. A comparison was also made with the translation efficiency of an expert medical translator. We conducted a pilot study in which two sets of 30 new and 30 updated guidelines were randomized to one of three groups. Comparable guidelines were translated (1) by certificated junior translators without medical specialization using the hybrid method, (2) by an experienced medical translator without this support, and (3) by the same junior translators without the support of the validated translation memory. A medical proofreader who was blinded for the translation procedure, evaluated the translated guidelines for acceptability and adequacy. Translation speed was measured by recording translation and post-editing time. The human translation edit rate was calculated as a metric to evaluate the quality of the translation. A further evaluation was made of translation acceptability and adequacy. The average number of words per guideline was 1195 and the mean total translation time was 100.2 minutes/1000 words. No meaningful differences were found in the translation speed for new guidelines. The translation of updated guidelines was 59 minutes/1000 words faster (95% CI 2-115; P=.044) in the computer-aided group. Revisions due to terminology accounted for one third of the overall revisions by the medical proofreader. Use of the hybrid human and computer-aided translation by a non-expert translator makes the translation of updates of clinical practice guidelines faster and cheaper because of the benefits of translation memory. For the translation of new guidelines, there was no apparent benefit in comparison with the efficiency of translation unsupported by translation memory (whether by an expert or non-expert translator).

Perceptions of the environment appear to be associated with walking and cycling. We investigated the reasons for walking and cycling to or from work despite reporting an unsupportive route environment in a sample of commuters. This mixed-method analysis used data collected as part of the Commuting and Health in Cambridge study. 1164 participants completed questionnaires which assessed the travel modes used and time spent on the commute and the perceived environmental conditions on the route to work. A subset of 50 also completed qualitative interviews in which they discussed their experiences of commuting. Participants were included in this analysis if they reported unsupportive conditions for walking or cycling on their route (e.g. heavy traffic) in questionnaires, walked or cycled all or part of the journey to work, and completed qualitative interviews. Using content analysis of these interviews, we investigated their reasons for walking or cycling. 340 participants reported walking or cycling on the journey to work despite unsupportive conditions, of whom 15 also completed qualitative interviews. From these, three potential explanations emerged. First, some commuters found strategies for coping with unsupportive conditions. Participants described knowledge of the locality and opportunities for alternative routes more conducive to active commuting, as well as their cycling experience and acquired confidence to cycle in heavy traffic. Second, some commuters had other reasons for being reliant on or preferring active commuting despite adverse environments, such as childcare arrangements, enjoyment, having more control over their journey time, employers' restrictions on car parking, or the cost of petrol or parking. Finally, some survey respondents appeared to have reported not their own environmental perceptions but those of others such as family members or 'the public', partly to make a political statement regarding the adversity of active commuting in their setting. Participants report walking and cycling to work despite adverse environmental conditions. Understanding this resilience might be just as important as investigating 'barriers' to cycling. These findings suggest that developing knowledge of safe walking and cycling routes, improving cycling confidence and restricting workplace parking may help to encourage walking and cycling to and from work.

Young Adults With Type 1 Diabetes: Romantic Relationships and Implications for Well-Being.

Helgeson, Vicki S

2017-05-01

The study goal was to examine whether young adults with type 1 diabetes involve romantic partners in their illness, and, if so, how their involvement is related to relationship quality and psychological well-being. A total of 68 people (mean age 25.5 years, [SD 3.7 years]) with type 1 diabetes (mean diabetes duration 6 years, [SD 6.7]) involved in a romantic relationship (mean relationship duration 25 months, [SD 27 months]) completed phone interviews. Communal coping (shared illness appraisal and collaborative problem-solving), partner supportive and unsupportive behavior, relationship quality, and psychological well-being were assessed with standardized measures. The study was partly descriptive in identifying the extent of communal coping and specific supportive and unsupportive behaviors and partly correlational in connecting communal coping and supportive or unsupportive behaviors to relationship quality and psychological well-being. Descriptive findings showed that partners were somewhat involved in diabetes, but communal coping was less common compared to other chronically ill populations. The most common partner supportive behaviors were emotional and instrumental support. The most common partner unsupportive behavior was worry about diabetes. Correlational results showed that communal coping was related to greater partner emotional and instrumental support, but also to greater partner overprotective and controlling behaviors ( P <0.01 for all). Communal coping was unrelated to relationship quality or psychological distress. Partner overinvolvement in diabetes management had a mixed relation to outcomes, whereas partner underinvolvement was uniformly related to poor outcomes. People with type 1 diabetes may benefit from increased partner involvement in illness. This could be facilitated by health care professionals.

Objective: To investigate surface electromyographic (EMG) activity of the rectus abdominus and external oblique abdominus muscles during pelvic-tilt and abdominal-hollowing exercises performed in different positions. Design and Setting: 2 × 3 (exercise by position) within-subjects design with repeated measures on both factors. All testing was performed in a university laboratory. Subjects: Twenty-six healthy, active young adult females. Measurements: Surface EMG activity was recorded from the left and right rectus abdominus and external oblique muscles while the 2 exercises (pelvic tilt and abdominal hollowing) were performed in different positions (standard, legs supported, and legs unsupported). The standard position was supine in the crook-lying position, the supported position was with hips and knees flexed to 90° and legs supported on a platform, and the unsupported position was with hips and knees flexed to 90° without external support. Peak EMG activity was normalized to a maximum voluntary isometric contraction for each muscle. Results: For the rectus abdominus, there was an interaction between position and activity. Abdominal hollowing produced significantly less activity than the pelvic tilt in all positions. The difference between the 2 exercises with the legs unsupported was of a greater magnitude than the other 2 positions. For the external obliques, there was significantly lower activity during the abdominal hollowing compared with the pelvic tilting. The greatest muscle activity occurred with the legs-unsupported position during both exercises. Conclusions: Abdominal-hollowing exercises produced less rectus abdominus and external oblique activity than pelvic-tilting exercises. Abdominal hollowing may be performed with minimal activation of the large global abdominal muscles. PMID:15085209

Unfortunately, not all organizations are supportive of employees' family lives. Family unsupportive workplaces can be stressful for all employees and particularly for pregnant women, who carry a physical reminder of their family life. In the present study, we draw on conservation of resources (COR) theory (Hobfoll, 1989, 2001) to investigate how women manage family unsupportive organizational perceptions during pregnancy via social identity-based impression management behaviors as well as how these strategies relate to changes in stress and changes in conflict between work and family. Specifically, we find that image maintenance strategies-impression management strategies aimed at maintaining one's prepregnancy image-are associated with decreases in work stress and work-family conflict over the course of pregnancy, while decategorization-impression management strategies aimed at avoiding negative outcomes by hiding the pregnancy or dodging the issue-are related to increases in work-family conflict. These results suggest strategies for both organizations and pregnant workers to decrease stress during a time when health is vital for both mother and baby.

Dynamic properties of a diruthenium complex with ligand-unsupported Ru-Ru triple bonds, Na 2[Ru 2(3,6-DTBCat) 4] ( 1), were studied using variable-temperature 1H NMR. Structural freedom derived from the ligand-unsupported structure leads to torsional motion about the Ru-Ru bonds in THF and in DMF. The observed solvent dependency corresponds to the electrostatic interactions between the diruthenium complex and Na + counter cations, which are sensitive to the polarity of solvents. In addition, a new diruthenium complex, [{Na(THF) 2(H 2O)}{Na(THF) 0.5(H 2O)}{Ru 2(3,6-DTBCat) 2(H 4Cat) 2}] ( 2·2.5THF·2H 2O), with a ligand-unsupported Ru-Ru bond surrounded by two different kinds of catecholate derivatives, has been synthesized and crystallographically characterized. The complex, which was characterized by single-crystal structural analysis, will provide an opportunity to investigate not only static molecular structures but also dynamic physicochemical properties in comparison with analogues containing four identical catecholate derivatives.

The molecular structures and physicochemical properties of diruthenium complexes with ligand-unsupported Ru-Ru bonds, generally formulated as [A2{Ru2(DTBCat)4}] (DTB = 3,5- or 3,6-di-tert-butyl; Cat(2-) = catecholate), were studied in detail by changing the countercations. First, the binding structures of the cations in a family of [{A(DME)n}2{Ru2(3,5-DTBCat)4}] (n = 2 for A+ = Li+ and Na+ and n = 1 for A+ = K+ and Rb+) were systematically examined to reveal the effects of the cations on the molecular structures and electrochemical properties. Second, the complex (n-Bu4N)2[Ru2(3,6-DTBCat)4] with a cation-free structure was synthesized using tetra-n-butylammonium cations. The complex clearly demonstrates first that the ligand-unsupported Ru-Ru bonds are essentially stabilized by the dianionic nature of the catecholate derivatives without any other bridging or supporting species. In contrast, the redox potentials and absorption spectra of the complexes can sensitively respond to the countercations depending upon the polarity of the solvents.

The crystal structure of a binuclear Mn(III) complex of a scorpiand-like ligand (L) displays an unsupported single oxo bridging ligand with a Mn(III)-O-Mn(III) angle of 174.7°. Magnetic susceptibility measurements indicate strong antiferromagnetic coupling between the two metal centers. DFT calculations have been carried out to understand the magnetic behavior and to analyze the nature of the observed Jahn-Teller distortion. Paramagnetic (1)H NMR has been applied to rationalize the formation and magnetic features of the complexes formed in solution.

Challenging clinical learning environments: experiences of undergraduate nursing students.

Clinical learning is an essential component of becoming a nurse. However at times, students report experiencing challenging clinical learning environments (CCLE), raising questions regarding the nature of a challenging clinical learning environment, its impact on students' learning and how students might respond within a CCLE. Using an Interpretive Descriptive study design, researchers held focus groups with 54 students from two Canadian sites, who self-identified as having experienced a CCLE. Students defined a CCLE as affected by relationships in the clinical area and by the context of their learning experiences. CCLE decreased students' learning opportunities and impacted on them as persons. As students determined which relationships were challenging, they tapped other resources and they used strategies to rebuilt, reframe, redirect and/or retreat relative to the specific challenge. Relationships also acted as buffers to unsupportive practice cultures. Implications for practice and research are addressed. Copyright © 2013 Elsevier Ltd. All rights reserved.

Young Adults With Type 1 Diabetes: Romantic Relationships and Implications for Well-Being

PubMed Central

2017-01-01

Objective. The study goal was to examine whether young adults with type 1 diabetes involve romantic partners in their illness, and, if so, how their involvement is related to relationship quality and psychological well-being. Methods. A total of 68 people (mean age 25.5 years, [SD 3.7 years]) with type 1 diabetes (mean diabetes duration 6 years, [SD 6.7]) involved in a romantic relationship (mean relationship duration 25 months, [SD 27 months]) completed phone interviews. Communal coping (shared illness appraisal and collaborative problem-solving), partner supportive and unsupportive behavior, relationship quality, and psychological well-being were assessed with standardized measures. The study was partly descriptive in identifying the extent of communal coping and specific supportive and unsupportive behaviors and partly correlational in connecting communal coping and supportive or unsupportive behaviors to relationship quality and psychological well-being. Results. Descriptive findings showed that partners were somewhat involved in diabetes, but communal coping was less common compared to other chronically ill populations. The most common partner supportive behaviors were emotional and instrumental support. The most common partner unsupportive behavior was worry about diabetes. Correlational results showed that communal coping was related to greater partner emotional and instrumental support, but also to greater partner overprotective and controlling behaviors (P <0.01 for all). Communal coping was unrelated to relationship quality or psychological distress. Partner overinvolvement in diabetes management had a mixed relation to outcomes, whereas partner underinvolvement was uniformly related to poor outcomes. Conclusion. People with type 1 diabetes may benefit from increased partner involvement in illness. This could be facilitated by health care professionals. PMID:28588377

Infant HIV infection is associated with delayed milestone attainment. The extent to which effective antiretroviral therapy (ART) prevents these delays is not well defined. Ages at attainment of milestones were compared between HIV-infected (initiated ART by age <5 months), and HIV-unexposed uninfected (HUU) infants. Kaplan Meier analyses were used to estimate and compare (log-rank tests) ages at milestones between groups. Adjusted analyses were performed using Cox proportional hazards models. Seventy-three HIV-infected on ART (median enrollment age 3.7 months) and 92 HUU infants (median enrollment age 1.6 months) were followed prospectively. HIV-infected infants on ART had delays in developmental milestone attainment compared to HUU: median age at attainment of sitting with support, sitting unsupported, walking with support, walking unsupported, monosyllabic speech and throwing toys were each delayed (all p-values <0.0005). Compared with HUU, the subset of HIV-infected infants with both virologic suppression and immune recovery at 6 months had delays for speech (delay: 2.0 months; P = 0.0002) and trend to later walking unsupported. Among HIV-infected infants with poor 6-month post-ART responses (lacking viral suppression and immune recovery) there were greater delays versus HUU for: walking unsupported (delay: 4.0 months; P = 0.0001) and speech (delay: 5.0 months; P < 0.0001). HIV infected infants with viral suppression on ART had better recovery of developmental milestones than those without suppression, however, deficits persisted compared to uninfected infants. Earlier ART may be required for optimized cognitive outcomes in perinatally HIV-infected infants. NCT00428116 ; January 22, 2007.

Unsupported or Turned Against: Understanding How Two Types of Negative Social Reactions to Sexual Assault Relate to Post-Assault Outcomes

PubMed Central

Relyea, Mark; Ullman, Sarah

2013-01-01

Social reactions to disclosures of sexual assault have significant effects on women’s post-assault outcomes (see Ullman, 2010, for a review). The Social Reactions Questionnaire (SRQ; Ullman, 2000) measures these reactions (as reported by survivors) and aggregates them into positive and negative scales. However, studies indicate that only some “negative” reactions have a negative valence for survivors whereas others produce a mixed (positive and negative) valence. The current study compares a one-primary-factor model of “negative reactions” to a model with two primary factors that we have labeled “turning against” and “unsupportive acknowledgement.” Results showed that although one primary factor was plausible, two primary factors provided a better fit to the data. To assess the discriminant validity of the two factors, we performed regressions predicting social support, psychological adjustment, and coping behaviors. Analyses supported the hypotheses that reactions of being turned against were related to social withdrawal, increased self-blame, and decreased sexual assertiveness whereas reactions of unsupportive acknowledgment were related to both adaptive and maladaptive coping. Against predictions, depression and PTSD were more related to receiving unsupportive acknowledgment than to receiving turning against reactions. Implications for interventions and research are discussed. Importantly, almost all women (94%) in our sample received reactions that acknowledged that an assault occurred but failed to provide support, and this lack of support was associated with worse coping than even more hostile reactions such as being blamed or stigmatized. Therefore, there seems a great need for effective programs to train community members to respond to survivors with the kind of emotional and tangible support that promotes better outcomes.

Apparatus and method for suppressing vibration and displacement of a bellows

DOEpatents

Kuklo, Thomas C.

1985-01-01

Flexible bellows are utilized between two systems, such as a pumping system and a process station, to partially absorb system vibrations and to compensate for misalignment between the systems. It is common practice to either clamp a rigid spacer between flanges of the two systems (FIG. 3B) to separate them from each other, or to maintain the bellows in unsupported relationship between these systems (FIG. 4B). In the former bellows arrangement, the rigid spacer transmits vibratory energy between the two systems and the bellows tends to function as an undamped or underdamped unit that resonates at its own frequency to create additional vibratory energy, transmitted to the systems. In the latter, unsupported bellows arrangement (FIG. 4B), the pressure differential prevalent between the fluid flowing through the bellows and ambient normally causes extension or retraction of the bellows and resulting misalignment problems. The present invention substantially solves the above vibration and misalignment problems by providing an inflatable tube (20) in surrounding relationship about a bellows (14) to suppress vibration and displacement thereof. A method for isolating first and second systems (11,12) from each other to prevent the transmission of vibratory energy therebetween comprises the steps of attaching at least one flexible bellows (14) between the systems (11,12), surrounding the bellows with an inflatable tube (20), and maintaining a predetermined pressure in the tube (20) to urge the tube in flexible contact with at least some of the convolutions of the bellows (14).

An artifact caused by undersampling optimal trees in supermatrix analyses of locally sampled characters.

PubMed

Simmons, Mark P; Goloboff, Pablo A

2013-10-01

Empirical and simulated examples are used to demonstrate an artifact caused by undersampling optimal trees in data matrices that consist mostly or entirely of locally sampled (as opposed to globally, for most or all terminals) characters. The artifact is that unsupported clades consisting entirely of terminals scored for the same locally sampled partition may be resolved and assigned high resampling support-despite their being properly unsupported (i.e., not resolved in the strict consensus of all optimal trees). This artifact occurs despite application of random-addition sequences for stepwise terminal addition. The artifact is not necessarily obviated with thorough conventional branch swapping methods (even tree-bisection-reconnection) when just a single tree is held, as is sometimes implemented in parsimony bootstrap pseudoreplicates, and in every GARLI, PhyML, and RAxML pseudoreplicate and search for the most likely tree for the matrix as a whole. Hence GARLI, RAxML, and PhyML-based likelihood results require extra scrutiny, particularly when they provide high resolution and support for clades that are entirely unsupported by methods that perform more thorough searches, as in most parsimony analyses.

Randomized, assessor-blinded trial. To evaluate the effectiveness of a 6-week task-specific training programme on the abilities of people with chronic spinal cord injuries to sit unsupported. NSW, Australia. Thirty adults with spinal cord injuries of at least 1-year duration were recruited. Participants in the training group (n=15) performed up to 1 h of task-specific training three times a week for 6 weeks. Participants in the control group (n=15) did not receive any training or additional therapy. Primary outcome measures were the Canadian Occupational Performance Measure (COPM), and tests of Upper Body Sway, Maximal Balance Range and donning and doffing a T-shirt (the T-shirt test). The between-group mean difference (95% confidence interval) for the maximal balance range was 64 mm (95% confidence interval 20 to 108 mm; P=0.006). There were no significant between-group mean differences for the COPM and the Upper Body Sway and T-shirt tests. This trial shows initial support for intensive task-specific training for improving the abilities of people with chronic spinal cord injuries to sit unsupported, although the real-world implications of the observed treatment effects are yet to be determined.

The decision to exclude agricultural and domestic workers from the 1935 Social Security Act.

PubMed

DeWitt, Larry

2010-01-01

The Social Security Act of 1935 excluded from coverage about half the workers in the American economy. Among the excluded groups were agricultural and domestic workers-a large percentage of whom were African Americans. This has led some scholars to conclude that policymakers in 1935 deliberately excluded African Americans from the Social Security system because of prevailing racial biases during that period. This article examines both the logic of this thesis and the available empirical evidence on the origins of the coverage exclusions. The author concludes that the racial-bias thesis is both conceptually flawed and unsupported by the existing empirical evidence. The exclusion of agricultural and domestic workers from the early program was due to considerations of administrative feasibility involving tax-collection procedures. The author finds no evidence of any other policy motive involving racial bias.

[Purpose] This study aimed to determine static balance according to hip joint angle of the unsupported leg during one-leg standing. [Subjects and Methods] Subjects included 45 healthy adult males and females in their 20s. During one-leg standing on the non-dominant leg, the position of the unsupported leg was classified according to hip joint angles of point angle was class. Static balance was then measured using a force plate with eyes open and closed. The total length, sway velocity, maximum deviation, and velocity on the mediolateral and anteroposterior axes of center of pressure were measured. [Results] In balance assessment with eyes open, there were significant differences between groups according to hip joint angle, except for maximum deviation on the anteroposterior axis. In balance assessment with eyes closed, there were significant differences between total length measurements at 0° and 30°, 60° and between 30° and 90°. There were significant differences between sway velocity measurements at 0° and 30° and between 30° and 90°. [Conclusion] Thus, there were differences in static balance according to hip joint angle. It is necessary to clearly identify the hip joint angle during one-leg standing testing.

Social support is one of the three strongest predictors of posttraumatic stress disorder (PTSD). In the present study, we aimed to assess the buffering power of overt socially supportive and unsupportive behaviors from the significant other, in a group with PTSD and a comparison group. A total of 46 individuals with PTSD and 42 individuals with obsessive-compulsive disorder (OCD) or panic disorder (PD) completed diagnostic interviews and an anxiety-oriented social interaction with a significant other. Heart rate of participants was continuously measured during this interaction and overt social behaviors from the significant other were recorded on videotape and coded using a validated system. Changes in heart rate in PTSD participants correlated negatively with changes in overt socially supportive behaviors from their significant other (r from -.36 to -.50, p < .05), while changes in overt unsupportive social behaviors from their significant other did not yield any significant correlation (r from -.01 to .05, p > .05). No such statistically significant association emerged in the group with OCD or PD (r from .01 to -.27, p > .05). This study sustain the buffering power of overt supportive behaviors from the significant other on heart rate changes in PTSD.

Palladium (Pd) nanoparticle catalysts were successfully synthesized within an aqueous phase using sodium carboxymethyl cellulose (CMC) as a capping ligand which offers a green alternative to conventional nanoparticle synthesis techniques. The CMC-stabilized Pd nanoparticles were subsequently dispersed within support materials using the incipient wetness impregnation technique for utilization in heterogeneous catalyst systems. The unsupported and supported (both calcined and uncalcined) Pd nanoparticle catalysts were characterized using transmission electron microscopy, energy dispersive x-ray spectrometry, x-ray diffraction, and Brunauer-Emmett-Teller surface area measurement and their catalytic activity toward the hydrodechlorination of trichloroethylene (TCE) in aqueous media was examined using homogeneous and heterogeneous catalyst systems, respectively. The unsupported Pd nanoparticles showed considerable activity toward the degradation of TCE, as demonstrated by the reaction kinetics. Although the supported Pd nanoparticle catalysts had a lower catalytic activity than the unsupported particles that were homogeneously dispersed in the aqueous solutions, the supported catalysts retained sufficient activity toward the degradation of TCE. In addition, the use of the hydrophilic Al2O3 support material induced a mass transfer resistance to TCE that affected the initial hydrodechlorination rate. This paper demonstrates that supported Pd catalysts can be applied to the heterogeneous catalytic hydrodechlorination of TCE.

The first experimental study of hydrodynamic perturbation evolution in a strong unsupported shock wave, which is immediately followed by a rarefaction wave, is reported. Our planar solid polystyrene laser-machined targets, 50 to 100 μm thick, rippled from the front side with a single-mode wavelength 30 or 45 μm and peak-to-valley amplitude 4 to 6 μm, were irradiated with a 350 ps long Nike KrF laser pulse at peak intensity of up to 330 TW/cm2. The perturbation evolution in the target was observed using face-on monochromatic x-ray radiography while the pulse lasted and for 3 to 4 ns after it ended. While the driving pulse was on, the areal mass modulation amplitude in the target was observed to grow by a factor of up to ~4 due to the ablative Richtmyer-Meshkov instability. After the end of the pulse, while the strong unsupported shock wave propagated through the unperturbed target, the theoretically predicted large oscillations of the areal mass [A. L. Velikovich et al., Phys. Plasmas 10, 3270 (2003)] were observed. Multiple phase reversals of the areal mass modulation have been detected. Work supported by DOE/NNSA and Office of Naval Research.

Expanding reproductive justice through a supportability reparative justice framework: the case of abortion in South Africa.

PubMed

Macleod, Catriona Ida

2018-04-03

Theoretical refinement of the concept of reproductive justice has been called for. In this paper, I propose the use of a supportability reparative justice approach. Drawing on intra-categorical intersectionality, the supportability aspect starts from the event of a pregnancy to unravel the interwoven embodied and social realities implicated in women experiencing pregnancy as personally supportable/unsupportable, and socially supported/unsupported. The reparative justice aspect highlights the need for social repair in the case of unsupportable pregnancies and relies on Ernesto Verdeja's critical theory of reparative justice in which he outlines four reparative dimensions. Using abortion within the South African context, I show how this framework may be put to use: (1) the facilitation of autonomous decision-making (individual material dimension) requires understanding women within context, and less emphasis on individual-driven 'choice'; (2) the provision of legal, safe state-sponsored healthcare resources (collective material dimension) demands political will and abortion service provision to be regarded as a moral as well as a healthcare priority; (3) overcoming stigma and the spoiled identities (collective symbolic dimension) requires significant feminist action to deconstruct negative discourses and to foreground positive narratives; and (4) understanding individual lived experiences (individual symbolic dimension) means deep listening within the social dynamics of particular contexts.

Children with autism spectrum disorders (ASD) face pervasive challenges in symbolic and social play development. The Integrated Play Groups (IPG) model provides intensive guidance for children with ASD to participate with typical peers in mutually engaging experiences in natural settings. This study examined the effects of a 12-week IPG intervention on the symbolic and social play of 48 children with ASD using a repeated measures design. The findings revealed significant gains in symbolic and social play that generalized to unsupported play with unfamiliar peers. Consistent with prior studies, the outcomes provide robust and compelling evidence that further validate the efficacy of the IPG model. Theoretical and practical implications for maximizing children's developmental potential and social inclusion in play are discussed.

2017-01-01

Objectives In January 2016, the 4 UK Chief Medical Officers released a public consultation regarding updated guidelines for low-risk alcohol consumption. This study aimed to assess responses to the updated guidelines using comments made on Twitter. Methods Tweets containing the hashtag #alcoholguidelines made during 1 week following the announcement of the updated guidelines were retrieved using the Twitter Archiver tool. The source, sentiment and themes of the tweets were categorised using manual content analysis. Results A total of 3061 tweets was retrieved. 6 sources were identified, the most prominent being members of the public. Of 821 tweets expressing sentiment specifically towards the guidelines, 80% expressed a negative sentiment. 11 themes were identified, 3 of which were broadly supportive of the guidelines, 7 broadly unsupportive and 1 neutral. Overall, more tweets were unsupportive (49%) than supportive (44%). While the most common theme overall was sharing information, the most common in tweets from members of the public encouraged alcohol consumption (15%) or expressed disagreement with the guidelines (14%), reflecting reactance, resistance and misunderstanding. Conclusions This descriptive analysis revealed a number of themes present in unsupportive comments towards the updated UK alcohol guidelines among a largely proalcohol community. An understanding of these may help to tailor effective communication of alcohol and health-related policies, and could inform a more dynamic approach to health communication via social media.

The meaning of social support for the critically ill patient.

Hupcey, J E

2001-08-01

Social support has been shown to be important for the critically ill patient. However, what constitutes adequate support for these patients has not been investigated. Thus, the purpose of this qualitative study was to investigate patients' perceptions of their need for and adequacy of the social support received while they were critically ill. Thirty adult patients who were critical during some point of their stay in the intensive care unit (ICU) stay were interviewed, once stable. Interviews were tape-recorded and began with an open-ended question regarding the ICU experience. This was followed by open-ended focused questions regarding social support, such as 'Who were your greatest sources of social support while you were critically ill?' 'What did they do that was supportive or unsupportive?' Data were analyzed according to Miles and Huberman (1994). The categories that emerged were need for social support based on patient perceptions (not number of visitors), quality of support (based on perceptions of positive and negative behaviors of supporters) and lack of support. This study found that quality of support was more important than the actual number of visitors. Patients with few visitors may have felt supported, while those with numerous visitors felt unsupported. Patients who felt unsupported also were more critical of the staff and the care they received. Nurses need to individually assess patients regarding their need for support, and assist family/friends to meet these needs.

Motor development—traditionally described in terms of age-related stages—is typically studied in the laboratory with participants of Western European descent. Cross-cultural studies typically focus on group differences in age-related stages relative to Western norms. We adopted a less traditional approach: We observed 5-month-olds and their mothers from six cultural groups around the world during one hour at home while they engaged in natural daily activities. We examined group differences in infants’ sitting proficiency, everyday opportunities to practice sitting, the surfaces on which sitting took place, and mothers’ proximity to sitting infants. Infants had opportunities to practice sitting in varied contexts—including ground, infant chairs, and raised surfaces. Proficiency varied considerably within and between cultural groups: 64% of the sample sat only with support from mother or furniture and 36% sat independently. Some infants sat unsupported for 20+ minutes, in some cases so securely that mothers moved beyond arms’ reach of their infants even while infants sat on raised surfaces. Our observations of infant sitting across cultures provide new insights into the striking range of ability, varied opportunities for practice, and contextual factors that influence the proficiency of infant motor skills.

Novel applications of X-ray photoelectron spectroscopy on unsupported nanoparticles

NASA Astrophysics Data System (ADS)

Kostko, Oleg; Xu, Bo; Jacobs, Michael I.; Ahmed, Musahid

X-ray photoelectron spectroscopy (XPS) is a powerful technique for chemical analysis of surfaces. We will present novel results of XPS on unsupported, gas-phase nanoparticles using a velocity-map imaging (VMI) spectrometer. This technique allows for probes of both the surfaces of nanoparticles via XPS as well as their interiors via near edge X-ray absorption fine structure (NEXAFS) spectroscopy. A recent application of this technique has confirmed that arginine's guanidinium group exists in a protonated state even in strongly basic solution. Moreover, the core-level photoelectron spectroscopy can provide information on the effective attenuation length (EAL) of low kinetic energy electrons. This contradictory value is important for determining the probing depth of XPS and in photolithography. A new method for determining EALs will be presented.

The myths of coping with loss in undergraduate psychiatric nursing books.

2010-12-01

Nurses often help patients cope with loss. Recent research has cast doubt on the validity of early theories about loss and grief commonly taught to nurses. We systematically examined the accuracy of information on coping with loss presented in 23 commonly used undergraduate psychiatric nursing books. All 23 books contained at least one unsupported assumption (myth) about loss and grief. In 78% of these books, authors described four or more myths and only one evidence-based finding about coping with loss. On balance most books provided details on the myths about grief and loss with minimal discussion of the current evidence. Authors of psychiatric nursing books continue to disseminate unsupported theories about grief responses without adequately acknowledging evidence challenging core assumptions underlying them.

[The use of opium in Roman society and the dependence of Princeps Marcus Aurelius].

PubMed

Trancas, Bruno; Borja Santos, Nuno; Patrício, Luís D

2008-01-01

Opium was known and frequently used in Roman society. Medical practice recognized its usefulness as an analgesic, soporific, anti-tussic or anti-diarrheic agent, as well as other currently unsupported uses with quasi-magical properties. It was additionally used as an ingredient in antidotes, panaceas and poisons. The authors present a non-exhaustive compilation of opium use according to medical doctors, writers and encyclopaedists of the time. Mythological and literary representations of the opium poppy reflected its diverse roles, being associated with prosperity and fertility, sleep, death and the underworld and with the art of medicine. Despite its free and routine use, there is no solid evidence of addiction, except the putative case of emperor Marcus Aurelius, consistently reported as one of the most likely cases of addiction to opium.

Catalytic Properties of Unsupported Palladium Nanoparticle Surfaces Capped with Small Organic Ligands

PubMed Central

Gavia, Diego J.

2015-01-01

This Minireview summarizes a variety of intriguing catalytic studies accomplished by employing unsupported, either solubilized or freely mobilized, and small organic ligand-capped palladium nanoparticles as catalysts. Small organic ligands are gaining more attention as nanoparticle stabilizers and alternates to larger organic supports, such as polymers and dendrimers, owing to their tremendous potential for a well-defined system with spatial control in surrounding environments of reactive surfaces. The nanoparticle catalysts are grouped depending on the type of surface stabilizers with reactive head groups, which include thiolate, phosphine, amine, and alkyl azide. Applications for the reactions such as hydrogenation, alkene isomerization, oxidation, and carbon-carbon cross coupling reactions are extensively discussed. The systems defined as “ligandless” Pd nanoparticle catalysts and solvent (e.g. ionic liquid)-stabilized Pd nanoparticle catalysts are not discussed in this review. PMID:25937846

Objective To examine the perceived effect of teaching clinical skills and associated teacher training programmes on general practitioners' morale and clinical practice. Design Qualitative semistructured interview study. Setting General practices throughout north London. Subjects 30 general practitioners who taught clinical skills were asked about the effect of teaching and teacher training on their morale, confidence in clinical and teaching skills, and clinical practice. Results The main theme was a positive effect on morale. Within teacher training this was attributed to developing peer and professional support; improved teaching skills; and revision of clinical knowledge and skills. Within teaching this was attributed to a broadening of horizons; contact with enthusiastic students; increased time with patients; improved clinical practice; improved teaching skills; and an improved image of the practice. Problems with teaching were due to external factors such as lack of time and space and anxieties about adequacy of clinical cover while teaching. Conclusions Teaching clinical skills can have a positive effect on the morale of general practitioner teachers as a result of contact with students and peers, as long as logistic and funding issues are adequately dealt with. Key messagesThe increase in community based teaching of clinical skills requires an increase in the number of general practitioner teachersLittle evidence is available about the effect of teaching of clinical skills and teacher training on general practitioner teachers and practicesGeneral practitioner teachers reported an increase in morale, improvements in clinical skills, and changes in clinical practice and in practice infrastructure as a result of teaching and trainingGeneral practitioner teachers reported problems because of pressure on time, lack of space, problems recruiting patients, and unsupportive practice partnersPositive effects on morale and clinical practice may be important for sustainable teaching and continuing medical education PMID:10541508

Identifying knowledge-attitude-practice gaps to enhance HPV vaccine diffusion.

PubMed

Cohen, Elisia L; Head, Katharine J

2013-01-01

To examine differences in knowledge, attitudes, and related practices among adopters and nonadopters of the human papillomavirus (HPV) vaccine, the researchers conducted 83 in-depth interviews with 18- to 26-year-old women. The study identified knowledge-attitude-practice gaps in the context of the HPV vaccine to explain why diffusion of a preventive innovation (such as the HPV vaccine) requires targeted risk communication strategies in order to increase demand. Salient findings included similarities between vaccinated and unvaccinated women's lack of knowledge and uncertainties about HPV and cervical cancer. Vaccinated women who had no knowledge of HPV or no-risk/low-risk perceptions of HPV reported receiving vaccination, indicating HPV risk protection behavior could precede knowledge acquisition for vaccinated women. These vaccinated women identified an interpersonal network supportive of vaccination and reported supportive social influences. Among unvaccinated women, unsupportive vaccination attitudes included low perceived personal risk of HPV. In contrast, unvaccinated women often cited erroneous beliefs that HPV could be avoided by abstinence, monogamy, and knowledge of their partners' sexual history as reasons that the vaccine was not personally relevant. Unvaccinated women cited interpersonal influences that activated short- and long-term vaccination safety and efficacy concerns. Different levels of fear regarding the HPV vaccine may underlie (a) attitudinal differences between vaccinated and unvaccinated women in perceived vaccination value and (b) attitude-practice gaps.

Barriers to standard precautions adherence in a dental school in Iran: a qualitative study.

2014-07-01

Setting up good infection control practices in educational institutions is crucial in shaping future health professionals. The implementation of standard precautions (SPs) in Iranian dental schools has not been explored qualitatively to identify barriers to good practice. Twelve focus group discussions and 8 semistructured interviews were conducted with students, residents, and staff members (n = 83) of the Shiraz University of Medical Sciences Dental School. The interview guide addressed performance, subjective norms, and behavioral control domains of SP-related behaviors. Thematic analysis was performed manually to identify barriers to SP practices. Proximal factors of poor SP adherence were a lack of knowledge and technical difficulties. These factors were compounded by intermediate factors in the work environment: lack of facilities, heavy workload, patient expectations, interprofessional conflicts, and lack of good role models. Two underlying distal factors were financial issues and unsupportive organizational culture. The social constructionism theory was useful in analyzing the situation and suggesting an educational approach as part of the solution. Complex and intertwined barriers of SP adherence were found in this dental school. A social construction approach may assist in addressing these problems by shifting the culture through education to construct a contextual new knowledge. Further research in medical sociology of SP practices would be useful. Copyright © 2014 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Mosby, Inc.

Social constraints and quality of life among Chinese-speaking breast cancer survivors: a mediation model.

PubMed

You, Jin; Lu, Qian

2014-11-01

Literature has revealed detrimental effects of unsupportive interpersonal interactions on adjustment to cancer. However, no studies have examined this effect and the underlying psychological pathways among Chinese-speaking breast cancer survivors. The study investigated the relationship between social constraints and adjustment to cancer and the underlying psychological pathways among Chinese-speaking breast cancer survivors. Chinese-speaking breast cancer survivors (N = 120) completed a questionnaire package assessing social constraints, intrusive thoughts, affect, and quality of life. Results revealed a negative relationship between social constraints and quality of life. Such a relationship between social constraints and quality of life was mediated by negative affect and intrusive thoughts, while the association of intrusive thoughts and quality of life were completely mediated by positive and negative affect. Findings highlight the negative association between unsupportive interpersonal interactions and adjustment through cognitive and affective pathways among Chinese-speaking breast cancer survivors.

Synthesis of an un-supported, high-flow ZSM-22 zeolite membrane

2006-10-10

Novel methods for synthesizing wholly un-supported, high-flow catalytic membranes consisting of 100% crystalline ZSM-22 crystals with no binder phase, having sufficient porosity to allow high Weight Hourly Space Velocities of feedstock to pass through without generating back pressure. The ZSM-22 membranes perform favorably to existing bulk ZSM-22 catalysts (e.g., via 1-butene conversion and selectivity). The method of membrane synthesis, based on Vapor Phase Transport, allows free-standing, binder-less membranes to be fabricated in varied geometries and sizes so that membranes can be tailor-made for particular geometries applications. The ZSM-22 precursor gel may be consolidated into a semi-cohesive body prior to vapor phase crystallization, for example, by uniaxial pressing. These crystalline membranes may be modified by ion exchange, pore ion exchange, framework exchange, synthesis modification techniques to incorporate other elements into the framework, such as K, H, Mg, Zn, V, Ga, and Pt.

The discovery of molecular metal-metal bonds has been of fundamental importance to the understanding of chemical bonding. For the actinides, examples of unsupported metal-metal bonds are relatively uncommon, consisting of Cp{sub 3}U-SnPh{sub 3}, and several actinide-transition metal complexes. Traditionally, bonding in the f-elements has been described as electrostatic; however, elucidating the degree of covalency is a subject of recent research. In carbon monoxide complexes of the trivalent uranium metallocenes, decreased {nu}{sub CO} values relative to free CO suggest that the U(III) atom acts as a {pi}-donor. Ephritikhine and coworkers have demonstrated that {pi}-accepting ligands can differentiate trivalent lanthanide and actinidemore » ions, an effect that renders this chemistry of interest in the context of nuclear waste separation technology.« less

Procedural errors in air traffic control: effects of traffic density, expertise, and automation.

PubMed

Di Nocera, Francesco; Fabrizi, Roberto; Terenzi, Michela; Ferlazzo, Fabio

2006-06-01

Air traffic management requires operators to frequently shift between multiple tasks and/or goals with different levels of accomplishment. Procedural errors can occur when a controller accomplishes one of the tasks before the entire operation has been completed. The present study had two goals: first, to verify the occurrence of post-completion errors in air traffic control (ATC) tasks; and second, to assess effects on performance of medium term conflict detection (MTCD) tools. There were 18 military controllers who performed a simulated ATC task with and without automation support (MTCD vs. manual) in high and low air traffic density conditions. During the task, which consisted of managing several simulated flights in an enroute ATC scenario, a trace suddenly disappeared "after" the operator took the aircraft in charge, "during" the management of the trace, or "before" the pilot's first contact. In the manual condition, only the fault type "during" was found to be significantly different from the other two. On the contrary, when in the MTCD condition, the fault type "after" generated significantly less errors than the fault type "before." Additionally, automation was found to affect performance of junior controllers, whereas seniors' performance was not affected. Procedural errors can happen in ATC, but automation can mitigate this effect. Lack of benefits for the "before" fault type may be due to the fact that operators extend their reliance to a part of the task that is unsupported by the automated system.

Robotic surgery to remove a cancerous prostate has become a popular treatment. Internet marketing of this surgery provides an intriguing case study of direct-to-consumer promotions of medical devices, which are more loosely regulated than pharmaceutical promotions. We investigated whether the claims made in online promotions of robotic prostatectomy were consistent with evidence from comparative effectiveness studies. After performing a search and crosssectional analysis of websites that mentioned the procedure, we found that many sites claimed benefits that were unsupported by evidence and that 42 percent of the sites failed to mention risks. Most sites were published by hospitals and physicians, which the public may regard as more objective than pages published by manufacturers. Unbalanced information may inappropriately raise patients’ expectations. Increasing enforcement and regulation of online promotions may be beyond the capabilities of federal authorities. Thus, the most feasible solution may be for the government and medical societies to promote the production of balanced educational material. PMID:22492893

2007-01-01

The objective of this research was to study and identify ergonomic deficiencies in computer workstation design in typical offices. Physical measurements and a questionnaire were used to study 40 workstations. Major ergonomic deficiencies were found in physical design and layout of the workstations, employee postures, work practices, and training. The consequences in terms of user health and other problems were significant. Forty-five percent of the employees used nonadjustable chairs, 48% of computers faced windows, 90% of the employees used computers more than 4 hrs/day, 45% of the employees adopted bent and unsupported back postures, and 20% used office tables for computers. Major problems reported were eyestrain (58%), shoulder pain (45%), back pain (43%), arm pain (35%), wrist pain (30%), and neck pain (30%). These results indicated serious ergonomic deficiencies in office computer workstation design, layout, and usage. Strategies to reduce or eliminate ergonomic deficiencies in computer workstation design were suggested.

Perceptions of barriers to paternal presence and contribution during childbirth: an exploratory study from Syria.

2013-03-01

The barriers that face fathers during childbirth are an understudied phenomenon. The objective of our study was to explore Syrian parents' perceptions of barriers to paternal presence and contribution during childbirth. A descriptive phenomenological qualitative approach based on Colaizzi's method was used with a purposive sample of 23 mothers and 14 fathers recruited from a major public maternity hospital in Syria. In our study, four themes on barriers to paternal presence and contribution during childbirth were found: 1) sociocultural influences and rigidity; 2) being unprepared; 3) unsupportive policies and attitudes; and 4) unfavorable reactions and circumstances. Common and current sociocultural norms in Syria do not encourage fathers to be present or contribute during childbirth. Therefore, establishing culturally sensitive supportive policies and practices is a vital step toward overcoming these barriers. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

Parent–Child Acculturation, Parenting, and Adolescent Depressive Symptoms in Chinese Immigrant Families

2009-01-01

Using a sample of 388 father–adolescent and 399 mother–adolescent dyads in Chinese immigrant families, the current investigation tested Portes and Rumbaut's (1996) assertion that generational dissonance may indicate a family context that places children at increased risk for adverse outcomes. Study findings suggest that a high discrepancy in father–adolescent acculturation levels relates significantly to more adolescent depressive symptoms. The study further demonstrates that the quality of the parenting relationship between fathers and adolescents operates as a mediator between father–adolescent acculturation discrepancy and adolescent depressive symptoms. Specifically, a high level of discrepancy in American orientation between fathers and adolescents is associated with unsupportive parenting practices, which, in turn, are linked to more adolescent depressive symptoms. These relationships are significant even after controlling for the influence of family socioeconomic status and parents’ and adolescents’ sense of discrimination within the larger society.

To provide an overview of the benefits of clinical data collected as a by-product of the care process, the potential problems with large aggregations of these data, the policy frameworks that have been formulated, and the major challenges in the coming years. This report summarizes some of the major observations from AMIA and IMIA conferences held on this admittedly broad topic from 2006 through 2013. This report also includes many unsupported opinions of the author. The benefits of aggregating larger and larger sets of routinely collected clinical data are well documented and of great societal benefit. These large data sets will probably never answer all possible clinical questions for methodological reasons. Non-traditional sources of health data that are patient-sources will pose new data science challenges. If we ever hope to have tools that can rapidly provide evidence for daily practice of medicine we need a science of health data perhaps modeled after the science of astronomy.

Parent-offspring conflict over family size in current China.

PubMed

Liu, Jianghua; Duan, Chongli; Lummaa, Virpi

2017-05-06

In China, the recent replacement of the one-child policy with a two-child policy could potentially change family ecology-parents may switch investment from exclusively one child to two. The parent-offspring conflict theory provides testable hypotheses concerning possible firstborn opposition toward further reproduction of their mother, and who wins the conflict. We tested the hypotheses that if there is any opposition, it will differ between sexes, weaken with offspring age and family resource availability, and affect maternal reproductive decision-making. Using survey data of 531 non-pregnant mothers of only one child from Xi'an (China), logistic regression was used to examine effects of age, family income, and sex on the attitudes of firstborn children toward having a sibling; ordinal regression was used to investigate how such attitudes affect maternal intention to reproduce again. Firstborns' unsupportive attitude toward their mothers' further reproduction weakened with age and was overall more frequent in low-income families. Sons' unsupportive tendency displayed a somewhat U-shaped relationship, whereas daughters' weakened with family income; consequently, sons were more likely than daughters to be unsupportive in high-income families, suggesting a tendency to be more demanding. Forty-nine percent of mothers supported by their firstborns intended to reproduce again, whilst only 9% of mothers not supported by firstborns had such an intention. Our study contributes to evolutionary literature on parent-offspring conflict and its influence on female reproductive strategy in modern human societies, and has also important implications for understanding fertility patterns and conducting interventions in family conflict in China. © 2016 Wiley Periodicals, Inc.

Size effects in electronic and catalytic properties of unsupported palladium nanoparticles in electrooxidation of formic acid.

PubMed

Zhou, Wei Ping; Lewera, Adam; Larsen, Robert; Masel, Rich I; Bagus, Paul S; Wieckowski, Andrzej

2006-07-13

We report a combined X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), and chronoamperometry (CA) study of formic acid electrooxidation on unsupported palladium nanoparticle catalysts in the particle size range from 9 to 40 nm. The CV and CA measurements show that the most active catalyst is made of the smallest (9 and 11 nm) Pd nanoparticles. Besides the high reactivity, XPS data show that such nanoparticles display the highest core-level binding energy (BE) shift and the highest valence band (VB) center downshift with respect to the Fermi level. We believe therefore that we found a correlation between formic acid oxidation current and BE and VB center shifts, which, in turn, can directly be related to the electronic structure of palladium nanoparticles of different particle sizes. Clearly, such a trend using unsupported catalysts has never been reported. According to the density functional theory of heterogeneous catalysis, and mechanistic considerations, the observed shifts are caused by a weakening of the bond strength of the COOH intermediate adsorption on the catalyst surface. This, in turn, results in the increase in the formic acid oxidation rate to CO2 (and in the associated oxidation current). Overall, our measurements demonstrate the particle size effect on the electronic properties of palladium that yields different catalytic activity in the HCOOH oxidation reaction. Our work highlights the significance of the core-level binding energy and center of the d-band shifts in electrocatalysis and underlines the value of the theory that connects the center of the d-band shifts to catalytic reactivity.

Interlimb Differences in Coordination of Unsupported Reaching Movements

PubMed Central

Schaffer, Jacob E.; Sainburg, Robert L.

2017-01-01

Previous research suggests that interlimb differences in coordination associated with handedness might result from specialized control mechanisms that are subserved by different cerebral hemispheres. Based largely on the results of horizontal plane reaching studies, we have proposed that the hemisphere contralateral to the dominant arm is specialized for predictive control of limb dynamics, while the non-dominant hemisphere is specialized for controlling limb impedance. The current study explores interlimb differences in control of 3-D unsupported reaching movements. While the task was presented in the horizontal plane, participant’s arms were unsupported and free to move within a range of the vertical axis, which was redundant to the task plane. Results indicated significant dominant arm advantages for both initial direction accuracy and final position accuracy. The dominant arm showed greater excursion along a redundant axis that was perpendicular to the task, and parallel to gravitational forces. In contrast, the non-dominant arm better impeded motion out of the task-plane. Nevertheless, left arm task errors varied substantially more with shoulder rotation excursion than did dominant arm task errors. These findings suggest that the dominant arm controller was able to take advantage of the redundant degrees of freedom of the task, while non-dominant task errors appeared enslaved to motion along the redundant axis. These findings are consistent with a dominant controller that is specialized for intersegmental coordination, and a non-dominant controller that is specialized for impedance control. However, the findings are inconsistent with previously documented conclusions from planar tasks, in which non-dominant control leads to greater final position accuracy. PMID:28344068

Reactions on Twitter to updated alcohol guidelines in the UK: a content analysis.

2017-02-28

In January 2016, the 4 UK Chief Medical Officers released a public consultation regarding updated guidelines for low-risk alcohol consumption. This study aimed to assess responses to the updated guidelines using comments made on Twitter. Tweets containing the hashtag #alcoholguidelines made during 1 week following the announcement of the updated guidelines were retrieved using the Twitter Archiver tool. The source, sentiment and themes of the tweets were categorised using manual content analysis. A total of 3061 tweets was retrieved. 6 sources were identified, the most prominent being members of the public. Of 821 tweets expressing sentiment specifically towards the guidelines, 80% expressed a negative sentiment. 11 themes were identified, 3 of which were broadly supportive of the guidelines, 7 broadly unsupportive and 1 neutral. Overall, more tweets were unsupportive (49%) than supportive (44%). While the most common theme overall was sharing information, the most common in tweets from members of the public encouraged alcohol consumption (15%) or expressed disagreement with the guidelines (14%), reflecting reactance, resistance and misunderstanding. This descriptive analysis revealed a number of themes present in unsupportive comments towards the updated UK alcohol guidelines among a largely proalcohol community. An understanding of these may help to tailor effective communication of alcohol and health-related policies, and could inform a more dynamic approach to health communication via social media.

The Ross procedure is seldom offered to adults less than 60 years of age who require aortic valve replacement except in a few high-volume centers with documented expertise. Inserting the pulmonary autograft as an unsupported root replacement may lead to increasing reoperations on the aortic valve in the second decade. Of 333 patients undergoing the Ross procedure between October 1992 and June 2012, the study group of 310 consecutive patients (mean age ± standard deviation, 39.3±12.7 years (limits 16-63) had the aortic root size adjusted to match the pulmonary autograft, which was inserted as a root replacement, with the aorta closed up around it to provide autologous support. The mean follow-up time was 9.4 years; the actuarial survival was 97% at 16 years; and freedom from the composite of all reoperations on the aortic valve and late echocardiographic-detected aortic regurgitation greater than mild was 95% at 5 years, 94% at 10 years, and 93% at 15 years. Overall freedom from all reoperations on aortic and pulmonary valves was 97% at 5 years, 94% at 10 years, and 93% at 15 years. All results were better for the patients presenting with predominant aortic stenosis (98% freedom at 15 years) than for those with aortic regurgitation (p=0.01). Autologous support of the pulmonary autograft leads to excellent results in the groups presenting with aortic stenosis and mixed aortic stenosis/regurgitation and to good results for those presenting with pure aortic regurgitation. The Ross procedure, using one of the proven, durable techniques available, should be considered for more widespread adoption. Copyright © 2013 The Society of Thoracic Surgeons.

Liu, Chi; Qiu, Yi; Griffin, Michael J

2017-08-16

Biodynamic responses of the seated human body are usually measured and modelled assuming a single point of vibration excitation. With vertical vibration excitation, this study investigated how forces are distributed over the body-seat interface. Vertical and fore-and-aft forces were measured beneath the ischial tuberosities, middle thighs, and front thighs of 14 subjects sitting on a rigid flat seat in three postures with different thigh contact while exposed to random vertical vibration at three magnitudes. Measures of apparent mass were calculated from transfer functions between the vertical acceleration of the seat and the vertical or fore-and-aft forces measured at the three locations, and the sum of these forces. When sitting normally or sitting with a high footrest, vertical forces at the ischial tuberosities dominated the vertical apparent mass. With feet unsupported to give increased thigh contact, vertical forces at the front thighs were dominant around 8Hz. Around 3-7Hz, fore-and-aft forces at the middle thighs dominated the fore-and-aft cross-axis apparent mass. Around 8-10Hz, fore-and-aft forces were dominant at the ischial tuberosities with feet supported but at the front thighs with feet unsupported. All apparent masses were nonlinear: as the vibration magnitude increased the resonance frequencies decreased. With feet unsupported, the nonlinearity in the apparent mass was greater at the front thighs than at the ischial tuberosities. It is concluded that when the thighs are supported on a seat it is not appropriate to assume the body has a single point of vibration excitation. Copyright © 2017 Elsevier Ltd. All rights reserved.

The electronic cigarette industry is growing, with youth using e-cigarettes at higher rates than they are using cigarettes, and retail and online sales projected to reach $10 billion in 2017. Minimal regulation of the production and marketing of e-cigarettes exists to date, which has allowed companies to promote unsupported claims. We assessed the shipping, product features and packaging of a wide variety of e-cigarettes purchased online by adults and youth. The most popular internet e-cigarette vendors were identified from a larger study of internet tobacco vendors. Between August 2013 and June 2014, adults made 56 purchase attempts from online vendors, and youth made 98 attempts. Packages received were assessed for exterior and internal packaging features, including product information, health warnings and additional materials. We analysed a total of 125 orders featuring 86 unique brands of e-cigarettes. The contents were rarely indicated on package exteriors. Product information came with just 60% of orders and just 38.4% included an instruction manual. Only 44.6% of products included a health warning, and some had unsupported claims, such as lack of secondhand smoke exposure. Additionally, some products were leaking e-liquid and battery fluid on arrival. A large variety of e-cigarette products are manufactured and marketed to consumers. Many products do not include instructions for use, and unsupported claims are being presented to consumers. Effective federal regulation of the manufacturing, packaging, product information and health claims surrounding e-cigarettes is necessary to ensure consumers are presented with accurate e-cigarette use information.

Many of the disturbances resulting from dysregulations in the autonomous nervous system of children with cerebral palsy are rarely discussed in the doctor's praxis. Nevertheless, they are causes of trouble and worry for the parents. For this reason we started an inquiry into this matter. Questionnaires were sent to the parents of 452 C.P. patients. 374 were answered with sufficient care. The following factors were evaluated: sleep, bladder and bowel activity, temperature regulation, vomiting, sweating, blood circulation, growth. The C.P. children were compared to their own siblings especially to the next younger ones. The diagnoses were as follows: Spastic tetraplegia 197 patients. Spastic hemiplegia 44 patients, Athetosis 33 patients, Mixed cases of spasticity and athetosis 82 patients, Other 15 patients. The degrees of handicap in terms of motor development were: severe (unability to sit unsupported) 166 cases, moderate (unability to kneel or walk unsupported) 118 cases, mild (ability to kneel and/or walk unsupported) 87 cases. Summarized, the statements of the parents gave the following results: sleep disturbances: 169 cases (46%), constipation: 145 cases (39%), tendency towards temperature dysregulation: 112 cases (30%) , tendency towards increased vomiting: 91 cases (25%), sweating increased or decreased: 110 cases (30%), irregular and frequent voiding of bladder: 92 cases (25%), unstable regulation of blood circulation: 101 cases (27%), cold skin: 264 cases (71%), body-length deficit: 119 cases (32%), low-weight: 177 cases (48%), feet too small for age: 252 cases (68%). Results are related to diagnosis and severeness of handicap. In addition, it is discussed, whether there are relations between several of the investigated factors. The influence of the patients sex is discussed.

To investigate the effects of exercise on gait speed, when tested using walking aids and without, and whether effects differed according to amount of support in the test. A cluster-randomized controlled trial. The Umeå Dementia and Exercise (UMDEX) study was set in 16 nursing homes in Umeå, Sweden. One hundred forty-one women and 45 men (mean age 85 years) with dementia, of whom 145 (78%) habitually used walking aids. Participants were randomized to the high-intensity functional exercise program or a seated attention control activity. Blinded assessors measured 4-m usual gait speed with walking aids if any gait speed (GS), and without walking aids and with minimum amount of support, at baseline, 4 months (on intervention completion), and 7 months. Linear mixed models showed no between-group effect in either gait speed test at 4 or 7 months. In interaction analyses exercise effects differed significantly between participants who walked unsupported compared with when walking aids or minimum support was used. Positive between-group exercise effects on gait speed (m/s) were found in subgroups that walked unsupported at 4 and 7 months (GS: 0.07, P = .009 and 0.13, P < .001; and GS test without walking aids: 0.05, P = .011 and 0.07, P = .029, respectively). In people with dementia living in nursing homes exercise had positive effects on gait when tested unsupported compared with when walking aids or minimum support was used. The study suggests that the use of walking aids in gait speed tests may conceal exercise effects. Copyright © 2016 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Hopper, Darrel G.; Meyer, Frederick M.; Wodke, Kenneth E.

1999-08-01

Display technologies for the B-52 were selected some 40 years ago have become unsupportable. Electromechanical and old cathode ray tube technologies, including an exotic six-gun 13 in. tube, have become unsupportable due to the vanishing vendor syndrome. Thus, it is necessary to insert new technologies which will be available for the next 40 years to maintain the capability heretofore provided by those now out of favor with the commercial sector. With this paper we begin a look at the status of displays in the B-52H, which will remain in inventory until 2046 according to current plans. From a component electronics technology perspective, such as displays, the B-52H provides several 10-year life cycle cost (LCC) planning cycles to consider multiple upgrades. Three Productivity, Reliability, Availability, and Maintainability (PRAM) projects are reviewed to replace 1950s CRTs in several sizes: 3, 9, and 13 in. A different display technology has been selected in each case. Additional display upgrades in may be anticipated and are discussed.

To determine the frequency, experiences and correlates of sexual violence among female adolescents in Riyadh city, Kingdom of Saudi Arabia. A cross-sectional survey was conducted in 2 schools in Riyadh city for adolescent females starting from January 2008 for 3 months. Five classes with 25 students in each were randomly selected from intermediate and secondary grade of each school. Four hundred and nineteen students were included. A self-answering questionnaire was distributed and collected after 15 minutes by 3 research assistants. Forty-two adolescent students (10%) were exposed to sexual violence. Only 31% of the students were taught how to react to sexual violence. Students whose order was > or = 5th among siblings and who had unsupportive parents in discussing sexual issues were more exposed to sexual violence (chi2=4.02, p=0.044, chi2=4.24, p=0.039). Being > or = 5th in order among siblings and having unsupportive parents in discussing sexual issues were correlates for exposure to sexual violence.

A note on the estimation of the Pareto efficient set for multiobjective matrix permutation problems.

PubMed

Brusco, Michael J; Steinley, Douglas

2012-02-01

There are a number of important problems in quantitative psychology that require the identification of a permutation of the n rows and columns of an n × n proximity matrix. These problems encompass applications such as unidimensional scaling, paired-comparison ranking, and anti-Robinson forms. The importance of simultaneously incorporating multiple objective criteria in matrix permutation applications is well recognized in the literature; however, to date, there has been a reliance on weighted-sum approaches that transform the multiobjective problem into a single-objective optimization problem. Although exact solutions to these single-objective problems produce supported Pareto efficient solutions to the multiobjective problem, many interesting unsupported Pareto efficient solutions may be missed. We illustrate the limitation of the weighted-sum approach with an example from the psychological literature and devise an effective heuristic algorithm for estimating both the supported and unsupported solutions of the Pareto efficient set. © 2011 The British Psychological Society.

Unsupported Pt-Ni Aerogels with Enhanced High Current Performance and Durability in Fuel Cell Cathodes.

PubMed

Henning, Sebastian; Ishikawa, Hiroshi; Kühn, Laura; Herranz, Juan; Müller, Elisabeth; Eychmüller, Alexander; Schmidt, Thomas J

2017-08-28

Highly active and durable oxygen reduction catalysts are needed to reduce the costs and enhance the service life of polymer electrolyte fuel cells (PEFCs). This can be accomplished by alloying Pt with a transition metal (for example Ni) and by eliminating the corrodible, carbon-based catalyst support. However, materials combining both approaches have seldom been implemented in PEFC cathodes. In this work, an unsupported Pt-Ni alloy nanochain ensemble (aerogel) demonstrates high current PEFC performance commensurate with that of a carbon-supported benchmark (Pt/C) following optimization of the aerogel's catalyst layer (CL) structure. The latter is accomplished using a soluble filler to shift the CL's pore size distribution towards larger pores which improves reactant and product transport. Chiefly, the optimized PEFC aerogel cathodes display a circa 2.5-fold larger surface-specific ORR activity than Pt/C and maintain 90 % of the initial activity after an accelerated stress test (vs. 40 % for Pt/C). © 2017 Wiley-VCH Verlag GmbH & Co.

Monitoring of oxidation steps of ascorbic acid redox reaction by kinetics-sensitive voltcoulometry in unsupported and supported aqueous solutions and real samples.

PubMed

Orlický, Jozef; Gmucová, Katarína; Thurzo, Ilja; Pavlásek, Juraj

2003-04-01

Aqueous solutions of ascorbic acid in unsupported and supported aqueous solutions and real samples were studied by the kinetics-sensitive double-step voltcoulommetric method with the aim to contribute to a better understanding of its behavior in biological systems. The data obtained from measurements made on analytes prepared in the laboratory, as well as those made on real samples (some commercial orange drinks, flash of the fresh fruits) point to the redox reaction of L-ascorbic acid (L-AH2) being very sensitive to both the presence of dissolved gaseous species (O2, CO2) and the ionic strenght in the analyte. Either the dissolved gaseous species, or the higher ionic strength caused by both the presence of supporting electrolyte and increased total concentration of ascorbic acid, respectively, give birth to the degradation of L-AH2. Naturally, the highest percentage of L-AH2 was spotted in fresh fruit.

A qualitative study of advanced nurse practitioners' use of physical assessment skills in the community: shifting skills across professional boundaries.

PubMed

Raleigh, Mary; Allan, Helen

2017-07-01

To explore multiple perspectives on the use of physical assessment skills by advanced nurse practitioners in the UK. Physical assessment skills practices are embedded in advanced nursing practice roles in the UK. There is little evidence on how these skills are used by advanced nurse practitioners in the community. Case study. A qualitative interpretative single-embedded case study of 22 participants from South of England. A framework method analysed interview data collected by the researcher between March-August 2013. Participants included nurses, doctors, nurse educators and managers. Physical assessment skills education at universities is part of a policy shift to develop a flexible workforce in the UK. Shared physical assessment practices are less to do with role substitution and more about preparing practitioners with skills that are fit for purpose. Competence, capability and performance with physical assessment skills are an expectation of advanced nursing practice. These skills are used successfully by community advanced nurse practitioners to deliver a wide range of services in response to changing patient need. The introduction of physical assessment skills education to undergraduate professional preparation would create a firm foundation to develop these skills in postgraduate education. Physical assessment education prepares nurses with the clinical competencies to carry out healthcare reforms in the UK. Shared sets of clinical assessment competencies between disciplines have better outcomes for patients. Levels of assessment competence can depend on the professional attributes of individual practitioners. Unsupportive learning cultures can hinder professional development of advanced nursing practice. © 2016 John Wiley & Sons Ltd.

The heterogeneous catalytic ozonation on unsupported and supported oxides has been successfully tested for the removal of several refractory compounds in aqueous solution. In this work, alumina-supported nickel catalysts prepared by photodeposition and impregnation methods were compared in the catalytic ozonation of 2,4-dichlorophenoxyacetic acid (2,4-D). The catalysts were characterized by high-resolution electron microscopy and X-ray photoelectron spectroscopy. The photochemical decomposition of Ni acetylacetonate to produce Ni(OH)2, NiO, and traces of Ni° deposited on alumina was achieved in the presence of benzophenone as a sensitizer. A similar surface composition was found with the impregnated catalyst after its reduction with hydrogen at 500 °C and exposed to ambient air. Results indicated a higher initial activity and maleic acid (byproduct) concentration with the photodeposited catalyst (1 wt% Ni) compared to the impregnated catalyst (3 wt% Ni). These findings suggest the use of the photodeposition method as a simple and reliable procedure for the preparation of supported metal oxide/metal catalysts under mild operating conditions.

Critical evaluation of the adequacy of ecological models is urgently needed to enhance their utility in developing theory and enabling environmental managers and policymakers to make informed decisions. Poorly supported management can have detrimental, costly or irreversible impacts on the environment and society. Here, we examine common issues in ecological modelling and suggest criteria for improving modelling frameworks. An appropriate level of process description is crucial to constructing the best possible model, given the available data and understanding of ecological structures. Model details unsupported by data typically lead to over parameterisation and poor model performance. Conversely, a lack of mechanistic details may limit a model's ability to predict ecological systems’ responses to management. Ecological studies that employ models should follow a set of model adequacy assessment protocols that include: asking a series of critical questions regarding state and control variable selection, the determinacy of data, and the sensitivity and validity of analyses. We also need to improve model elaboration, refinement and coarse graining procedures to better understand the relevancy and adequacy of our models and the role they play in advancing theory, improving hind and forecasting, and enabling problem solving and management.

Hooked on a feeling: emotional labor as an occupational hazard of the post-industrial age.

PubMed

Andrews, Bonnie K; Karcz, Susan; Rosenberg, Beth

2008-01-01

Emotional labor is a subtle but serious occupational hazard that is likely to spread rapidly as the global service economy continues to grow. Emotional labor requires more than just acting friendly and being helpful to customers; the worker must manage his or her emotions to create a company-dictated experience for customers. The practice of emotional labor in an unsupportive work environment produces work-related stress, which has a wide range of potentially serious health effects. Though many employers do not acknowledge the existence of emotional labor, it is a real occupational hazard that may generate life-altering effects on physical and emotional health. While no official regulations or identification standards specify emotional labor as an occupational hazard, some guidelines exist regarding its outcome: occupational stress. Emotional labor should be recognized as an occupational hazard by the Occupational Safety and Health Administration (OSHA), but this hazard does not lend itself to regulation through standards. The business culture that demands its performance is questioned.

Nurses and Lifelong Learning: Creating "Makers and Shapers" or "Users and Choosers"?

PubMed

Butcher, Diane; Bruce, Anne

2016-04-01

How have the meaning and goals of lifelong learning for nurses shifted under neoliberal political policy? This article critically scrutinizes the political undercurrents of lifelong learning. While the original intent of lifelong learning was to foster intellectual, critical, social, and political citizen engagement (creating "makers and shapers" of social policy), instrumental learning-learning to meet practical economic ends-has taken priority and is instead creating marketable workers (creating "users and choosers"). International educational neoliberal policy reform has altered the very nature of education. Under pervasive neoliberal political influence, lifelong learning has become distorted as the goals of learning have shifted towards creating marketable workers who are expected, while unsupported, to engage in learning to ensure ongoing employability in an open market. By examining new understandings of lifelong learning, nurses can make informed choices as to whether they aspire to be a "user and chooser" or "maker and shaper" of lifelong learning in their workplaces. © 2015 Wiley Periodicals, Inc.

A moral justification for gay and lesbian civil rights legislation.

PubMed

Samar, V J

1994-01-01

This essay explores, in two parts, the problems of justifying civil rights legislation for gays, lesbians, and bisexuals. Part I shows that discrimination against gays and lesbians at least in respect to employment, housing, and public accommodations is an evil unsupported by ethical traditions in utilitarianism, rights theory, and communitarianism. It also shows that two theories, Kantian theory and natural law theory, which do support such discrimination on the claim that homoerotic behavior is universally or objectively immoral only do so because of a failure to make precise the concept of "natural" which underlies those theories. Part II argues that anti-discrimination legislation is both an appropriate and effective means to promote the idea that discrimination against lesbians and gays in respect to most employment, housing, and public accommodations is sufficiently injurious to both individuals and society that it should not be tolerated. The section also explains how such legislation might succeed practically in eliminating discrimination in these areas.

Zonal disintegration phenomenon was found in deep mining roadway surrounding rock. It seriously affects the safety of mining and underground engineering and it may lead to the occurrence of natural disasters. in deep mining roadway surrounding rock, tectonic stress in deep mining roadway rock mass, horizontal stress is much greater than the vertical stress, When the direction of maximum principal stress is parallel to the axis of the roadway in deep mining, this is the main reasons for Zonal disintegration phenomenon. Using ABAQUS software to numerical simulation of the three-dimensional model of roadway rupture formation process systematically, and the study shows that when The Direction of maximum main stress in deep underground mining is along the roadway axial direction, Zonal disintegration phenomenon in deep underground mining is successfully reproduced by our numerical simulation..numerical simulation shows that using ABAQUA simulation can reproduce Zonal disintegration phenomenon and the formation process of damage of surrounding rock can be reproduced. which have important engineering practical significance.

This study explored staff perceptions of the role of physical environment in dementia care facilities in affecting resident's behaviors and staff care practice. We conducted focus groups with staff (n = 15) in two purposely selected care facilities in Vancouver, Canada. Focus group participants included nurses, care aides, recreation staff, administrative staff, and family. Data analysis revealed two themes: (a) a supportive physical environment contributes positively to both quality of staff care interaction and residents' quality of life and (b) an unsupportive physical environment contributes negatively to residents' quality of life and thereby makes the work of staff more challenging. The staff participants collectively viewed that comfort, familiarity, and an organized space were important therapeutic resources for supporting the well-being of residents. Certain behaviors of residents were influenced by poor environmental factors, including stimulation overload, safety risks, wayfinding challenge, and rushed care This study demonstrates the complex interrelationships among the dementia care setting's physical environment, staff experiences, and residents' quality of life. © The Author(s) 2014.

We can only be healthy if we love ourselves: Queer AIDS NGOs, kinship, and alternative families of care in China.

PubMed

Miller, Casey James

2016-01-01

In this article, I draw from recent developments in the anthropological literatures on kinship and care to complicate and extend analyses of Chinese queer NGOs and AIDS activism. By highlighting the practical, moral, and political dimensions of daily life and work within Chinese queer NGOs, I argue that they constitute what I call "alternative families of care" by serving as important sources of material and emotional support and care for queer men, including increasing numbers of HIV-positive men who have sex with men, in a social climate that is still largely unsupportive and hostile toward both queerness and people living with HIV/AIDS. I also show how HIV/AIDS prevention and care are additionally regarded by many Chinese queer activists as an important political strategy for demonstrating the responsibility of queer men in the face of the AIDS crisis, achieving greater recognition from the government and society, and eventually attaining increased rights, including same-sex marriage.

A LONGITUDINAL, PERSON-CENTERED ANALYSIS OF EARLY HEAD START MOTHERS' PARENTING.

PubMed

Paschall, Katherine W; Mastergeorge, Ann M

2018-01-01

This study used a person-centered approach to examine stability and change in parenting typologies across early childhood. Profiles were associated within and across time with contextual covariates, including demographic characteristics, risk factors, and Early Head Start participation. Participants were drawn from the Early Head Start Research and Evaluation Project (N = 2, 876). Parenting profiles were identified based on observed parenting dimensions at 14, 24, and 36 months, and pre-Kindergarten (pre-K). Results suggested a four-profile solution at each time point: Supportive, Lukewarm (14 & 24 months)/Sufficient (36 months and pre-K), Harsh, and Detached. Supportive was the largest, most stable, and most likely transitioned into profile while Harsh and Detached represented rare profiles with moderate to low membership stability across time. Depression and family conflict emerged as important correlates of unsupportive parenting profiles both within and across time. Findings are discussed in terms of their relevance for both policy and implementation practices for low-income mothers with young children. © 2017 Michigan Association for Infant Mental Health.

Can hospital episode statistics support appraisal and revalidation? Randomised study of physician attitudes.

PubMed

Croft, Giles P; Williams, John G; Mann, Robin Y; Cohen, David; Phillips, Ceri J

2007-08-01

Hospital episode statistics were originally designed to monitor activity and allocate resources in the NHS. Recently their uses have widened to include analysis of individuals' activity, to inform appraisal and revalidation, and monitor performance. This study investigated physician attitudes to the validity and usefulness of these data for such purposes, and the effect of supporting individuals in data interpretation. A randomised study was conducted with consultant physicians in England, Wales and Scotland. The intervention group was supported by a clinician and an information analyst in obtaining and analysing their own data. The control group was unsupported. Attitudes to the data and confidence in their ability to reflect clinical practice were examined before and after the intervention. It was concluded that hospital episode statistics are not presently fit for monitoring the performance of individual physicians. A more comprehensive description of activity is required for these purposes. Improvements in the quality of existing data through clinical engagement at a local level, however, are possible.

Lost to the NHS: a mixed methods study of why GPs leave practice early in England.

2016-02-01

The loss of GPs in the early stages of their careers is contributing to the GP workforce crisis. Recruitment in the UK remains below the numbers needed to support the demand for GP care. To explore the reasons why GPs leave general practice early. A mixed methods study using online survey data triangulated with qualitative interviews. Participants were GPs aged <50 years who had left the English Medical Performers List in the last 5 years (2009-2014). A total of 143 early GP leavers participated in an online survey, of which 21 took part in recorded telephone interviews. Survey data were analysed using descriptive statistics, and qualitative data using thematic analysis techniques. Reasons for leaving were cumulative and multifactorial. Organisational changes to the NHS have led to an increase in administrative tasks and overall workload that is perceived by GP participants to have fundamentally changed the doctor-patient relationship. Lack of time with patients has compromised the ability to practise more patient-centred care, and, with it, GPs' sense of professional autonomy and values, resulting in diminished job satisfaction. In this context, the additional pressures of increased patient demand and the negative media portrayal left many feeling unsupported and vulnerable to burnout and ill health, and, ultimately, to the decision to leave general practice. To improve retention of young GPs, the pace of administrative change needs to be minimised and the time spent by GPs on work that is not face-to-face patient care reduced. © British Journal of General Practice 2016.

Trauma and fear in Australian midwives.

Toohill, J; Fenwick, J; Sidebotham, M; Gamble, J; Creedy, D K

2018-05-11

Relatively little is known about the extent of trauma and birth-related fear in midwives and how this might affect practice. (1) Determine prevalence of birth related trauma and fear in midwives and associations with midwives' confidence to advise women during pregnancy of their birth options and to provide care in labour. (2) Describe midwives' experiences of birth related trauma and/or fear. A mixed methods design. A convenience sample of midwives (n=249) completed an anonymous online survey. Descriptive and inferential statistics were used to analyse the quantitative data. Latent content analysis was used to extrapolate meaning from the 170 midwives who wrote about their experiences of personal and/or professional trauma. The majority of midwives (93.6%) reported professional (n=199, 85.4%) and/or personal (n=97, 41.6%) traumatic birth experiences. Eight percent (n=20) reported being highly fearful of birth. Trauma was not associated with practice concerns but fear was. Midwives categorised as having 'high fear' reported more practice concerns (Med 23.5, n=20) than midwives with 'low fear' (Med 8, n=212) (U=1396, z=-3.79, p<0.001, r=0.24). Reasons for personal trauma included experiencing assault, intervention and stillbirth. Professional trauma related to both witnessing and experiencing disrespectful care and subsequently feeling complicit in the provision of poor care. Feeling unsupported in the workplace and fearing litigation intensified trauma. High fear was associated with lower confidence to support childbearing women. Fear and trauma in midwives warrants further investigation to better understand the impact on professional practice. Copyright © 2018 Australian College of Midwives. Published by Elsevier Ltd.

2013-01-01

The purpose of this study was to explore the day-to-day life of mothers dealing with preschool children who have behavioral disorders and to explore the mothers' experiences with their children's health care. A qualitative design was used to explore mothers' experiences in their day-to-day lives. A purposive sample of eight mothers was interviewed in their homes. A recorded face-to-face format was used that included open-ended, semi-structured questions. Two major themes emerged from the day-to-day experiences of these mothers: "abandoning my other child" and "parenting in unsupportive environments". The theme of "parenting in unsupportive environments" reflects the frustrations the mothers felt in their day-to-day lives while trying to find help for their children. The theme of "abandoning my other child" refers to the siblings of the children with behavioral disorders being overlooked by the mothers because so much of the mothers' attention and time was given to the child with the behavioral disorder.

2018-03-01

Herein, surface-enhanced Raman scattering (SERS) activity of positively charged unsupported platinum nanoparticles (PtNPs) with ∼12 nm size and narrow size distribution, in an aqueous solution, towards neurotransmitters was monitored at 785 nm excitation wavelength. The pure PtNPs were synthetized by polyol method. Their morphology and structure were checked by scanning electron microscopy (SEM) and X-ray diffraction spectroscopy (XRD) measurements. As a neurotransmitter bombesin (BN), which exhibits autocrine effect on the growth of normal and tumour tissues, and its fragments from the C-terminal end: BN13-14, BN12-14, BN11-14, BN10-14, BN9-14, and BN8-14 (X-14 fragments of the BN amino acid sequence) were chosen. The collected spectra were interpreted and discussed. This is to determine the adsorption mode of bombesin onto the PtNPs surface and changes in this mode as a result of the bombesin backbone shortening from the N-terminal end. This is important from the point of using PtNPs as potential BN carrier into the cancerous tissue and antitumor drug.

Theoretical interpretation of Warburg's impedance in unsupported electrolytic cells.

PubMed

Barbero, G

2017-12-13

We discuss the origin of Warburg's impedance in unsupported electrolytic cells containing only one group of positive and one group of negative ions. Our analysis is based on the Poisson-Nernst-Planck model, where the generation-recombination phenomenon is neglected. We show that to observe Warburg-like impedance the diffusion coefficient of the positive ions has to differ from that of the negative ones, and furthermore the electrodes have to be not blocking. We assume that the non-blocking properties of the electrodes can be described by means of an Ohmic model, where the charge exchange between the cell and the external circuit is described by means of an electrode conductivity. For simplicity we consider a symmetric cell. However, our analysis can be easily generalized to more complicated situations, where the cell is not symmetric and the charge exchange is described by the Chang-Jaffe model, or by a linearized version of the Butler-Volmer equation. Our analysis allows justification of the expression for Warburg's impedance proposed previously by several groups, based on wrong assumptions.

A comparison of UV cross-linking and vacuum baking for nucleic acid immobilization and retention

Nierzwicki-Bauer, S.A.; Gebhardt, J.S.; Linkkila, L.

The effectiveness of UV cross-linking and in vacuo baking for the immobilization and retention of DNA to various solid supports was investigated. Optimal immobilization treatments for supported and unsupported nitrocellulose and nylon membranes were: UV cross-linking at 254 nm with an exposure of 120 milliJoules/cm{sup 2}, or baking in vacuo for two hours at 80{degrees}C. UV-immobilized nitrocellulose-based membranes showed no increase in sensitivity when compared to baked membranes. An increase in sensitivity was observed for UV-immobilized nylon membranes as compared with baked nylon membranes in some instances, although this varied within lots of the membranes tested. Repeated strippings and heterologousmore » reprobings resulted in loss of target DNA from UV-immobilized nylon membranes as compared to baked nylon membranes. Loss of target DNA from UV-immobilized nitrocellulose-based membranes due to repeated strippings and reprobings was even more pronounced. In vacuo baking of supported and unsupported nitrocellulose and nylon membranes was more effective for immobilization, and more importantly, for retention of target DNA through many reprobings of the same blot.« less

In this paper the most important problems in dating lake sediments with unsupported (210)Pb are summarized and the progress in gamma-spectrometry of the unsupported (210)Pb is discussed. The main topics of these studies concern sediment samples preparation for gamma-spectrometry, measurement techniques and data analysis, as well as understanding of accumulation and sedimentation processes in lakes. The vertical distributions of artificial ((137)Cs, (241)Am, (239)Pu) and natural radionuclides ((40)K, (210,214)Pb, (214)Bi) as well as stable trace elements (Fe, Mn, Pb) in sediment cores from four Swiss lakes were used as examples for the interpretation, inter-comparison and validation of depth-age relations established by three (210)Pb-based models (CF-CSR, CRS and SIT). The identification of turbidite layers and the influence of the turbidity flows on the accuracy of sediment dating is demonstrated. Time-dependent mass sedimentation rates in lakes Brienz, Thun, Biel and Lucerne are discussed and compared with published data. Copyright © 2015 Elsevier Ltd. All rights reserved.

Graphene-oxide-supported CuAl and CoAl layered double hydroxides as enhanced catalysts for carbon-carbon coupling via Ullmann reaction

2017-02-01

Two efficient catalyst based on CuAl and CoAl layered double hydroxides (LDHs) supported on graphene oxide (GO) for the carbon-carbon coupling (Classic Ullmann Homocoupling Reaction) are reported. The pure and hybrid materials were synthesised by direct precipitation of the LDH nanoparticles onto GO, followed by a chemical, structural and physical characterisation by electron microscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), surface area measurements and X-ray photoelectron spectroscopy (XPS). The GO-supported and unsupported CuAl-LDH and CoAl-LDH hybrids were tested over the Classic Ullman Homocoupling Reaction of iodobenzene. In the current study CuAl- and CoAl-LDHs have shown excellent yields (91% and 98%, respectively) at very short reaction times (25 min). GO provides a light-weight, charge complementary and two-dimensional material that interacts effectively with the 2D LDHs, in turn enhancing the stability of LDH. After 5 re-use cycles, the catalytic activity of the LDH/GO hybrid is up to 2 times higher than for the unsupported LDH.

Platinum Electrodeposition at Unsupported Electrochemically Reduced Nanographene Oxide for Enhanced Ammonia Oxidation

PubMed Central

2015-01-01

The electrochemical reduction of highly oxidized unsupported graphene oxide nanosheets and its platinum electrodeposition was done by the rotating disk slurry electrode technique. Avoiding the use of a solid electrode, graphene oxide was electrochemically reduced in a slurry solution with a scalable process without the use of a reducing agent. Graphene oxide nanosheets were synthesized from carbon platelet nanofibers to obtain highly hydrophilic layers of less than 250 nm in width. The graphene oxide and electrochemically reduced graphene oxide/Pt (erGOx/Pt) hybrid materials were characterized through different spectroscopy and microscopy techniques. Pt nanoparticles with 100 facets, clusters, and atoms at erGOx were identified by high resolution transmission electron microscopy (HRTEM). Cyclic voltammetry was used to characterize the electrocatalytic activity of the highly dispersed erGOx/Pt hybrid material toward the oxidation of ammonia, which showed a 5-fold current density increase when compared with commercially available Vulcan/Pt 20%. This is in agreement with having Pt (100) facets present in the HRTEM images of the erGOx/Pt material. PMID:24417177

Therefore, the aim of the current study was to have a closer look at usage and acceptability (i.e. expectancy, credibility, and satisfaction) of the intervention. Depressed participants (N=200) were given login codes for unsupported online CCBT. A track-and-trace system tracked which components were used. We used a 9-month follow-up period. Uptake was sufficient, but dropout was high. Many usage indices were positively associated with short-term depressive improvement, whereas only homework was related to long-term improvement. Acceptability was good and expectancy could predict long-term, but not short-term outcome. Associations between use of CCBT and improvement are merely correlational. Our sample was too depressed in relation to the scope of the intervention. We relied on online self-report measures. Analyses were exploratory in nature. Although CCBT might be a feasible and acceptable treatment for depression, means to improve treatment adherence are needed for moderately to severely depressed individuals.

Effects of Chinese Deforestation and Reforestation Policies on Sediment Sourcing in Yunnan, China

NASA Astrophysics Data System (ADS)

Henck Schmidt, A. C.; Bierman, P. R.; Sosa-Gonzalez, V.; Neilson, T. B.; Singleton, A.; Qiu, Y.; Bower, J.; Rood, D. H.

2015-12-01

Widespread deforestation from the 1960s through 1980s, blamed for catastrophic flooding in the lower Yangtze in 1998, prompted bans on logging and agriculture on steep slopes in western China. However, despite reports of extensive erosion resulting from the deforestation, sediment yield data show no corresponding increase during this time. Prior work suggested that if the deforestation increased erosion, the sediment is stored in floodplains, terraces, and alluvial fans throughout the region. In order to test this hypothesis, we sampled in-channel and overbank sediments at 38 locations, 19 of which are co-located with Chinese hydrology stations with at least five years of daily sediment yield data. Sediments were analyzed for meteoric and in situ 10-Be, unsupported 210-Pb, and 137-Cs. Unsupported 210-Pb activity is uniformly low throughout the study area and 137-Cs was found only in a few high-altitude, low-relief watersheds. Modern sediment yields, determined from Chinese data, are higher than long term in situ 10-Be-derived erosion rates in all but four watersheds, where we hypothesize sediment is being stored in alluvial features and agricultural terraces or that stochastic events such as landslides were not captured in the sediment yield data. Overall there is no relationship between topographic or climatic metrics, including slope, relief, or mean annual rainfall for any of the four isotopes except for a weak but statistically significant negative relationship between in situ 10-Be derived erosion rate and rainfall. Although paired in-channel and overbank samples are statistically indistinguishable for meteoric and in situ 10-Be, the overbank samples have lower unsupported 210-Pb activity, suggesting deeper sediment sourcing during the monsoon. In summary, in addition to suggesting differences between wet- and dry-season sediment sources, preliminary results support previous hypotheses regarding increased contemporary erosion and low hillslope-channel connectivity.

Mission Critical: Nursing Leadership Support for Compassion to Sustain Staff Well-being.

PubMed

Lown, Beth A

Compassion, the foundation of Nursing, is a source of both healing for those who suffer and of purpose and meaning for those who seek to heal others. Increasingly, however, the fast pace and volume of care and documentation requirements diminish time with patients and families and hinder the enactment of compassion. These issues and other aspects of the work environment decrease the satisfaction and well-being of professional caregivers and are contributing to a rising tide of burnout. Research suggests that employee engagement emerges from their satisfaction and well-being; however, it is difficult for an individual to engage when she or he feels depleted and unsupported. Nursing leaders and managers can play a significant role in support of compassionate practices for staff and improvement of the work environment and staff well-being. Compassion practices that recognize employees for the caring they show to patients and each other, and that provide the support needed to sustain their caring and compassion, are associated with significantly better patient ratings of their care experiences in hospitals and ambulatory settings. This article describes an example of a compassion practice, Schwartz Rounds®, a program that has been implemented internationally to enhance staff caring and compassion, teamwork, and psychological well-being. Schwartz Rounds have been included as a component of organizational initiatives to enhance staff well-being and patient experience, and as an individual program. Nurse leaders and managers who wish to engage their staff can do so by supporting their compassion and well-being.

Iron has been used previously in water decontamination, either unsupported or supported on clays, polymers, carbons or ceramics such as silica. However, the reported synthesis procedures are tedious, lengthy (involving various steps), and either utilise or produce toxic chemicals. Herein, the use of a simple, rapid, bio-inspired green synthesis method is reported to prepare, for the first time, a family of iron supported on green nanosilica materials (Fe@GN) to create new technological solutions for water remediation. In particular, Fe@GN were employed for the removal of arsenate ions as a model for potentially toxic elements in aqueous solution. Several characterization techniques were used to study the physical, structural and chemical properties of the new Fe@GN. When evaluated as an adsorption platform for the removal of arsenate ions, Fe@GN exhibited high adsorption capacity (69 mg of As per g of Fe@GN) with superior kinetics (reaching ∼35 mg As per g sorbent per hr) - threefold higher than the highest removal rates reported to date. Moreover, a method was developed to regenerate the Fe@GN allowing for a full recovery and reuse of the adsorbent in subsequent extractions; strongly highlighting the potential technological benefits of these new green materials.

Nurses and stress: recognizing causes and seeking solutions.

Happell, Brenda; Dwyer, Trudy; Reid-Searl, Kerry; Burke, Karena J; Caperchione, Cristina M; Gaskin, Cadeyrn J

2013-05-01

To identify, from the perspectives of nurses, occupational stressors and ways in which they may be reduced. Nurses commonly experience high levels of occupational stress, with negative consequences for their physical and psychological health, health-care organisations and community. There is minimal research on reducing occupational stress. Six focus groups were conducted with 38 registered nurses using a qualitative exploratory approach. Participants were asked to identify sources of occupational stress and possible workplace initiatives to reduce stress. Sources of occupational stress were: high workloads, unavailability of doctors, unsupportive management, human resource issues, interpersonal issues, patients' relatives, shift work, car parking, handover procedures, no common area for nurses, not progressing at work and patient mental health. Suggestions for reduction included: workload modification, non-ward-based initiatives, changing shift hours, forwarding suggestions for change, music, special events, organisational development, ensuring nurses get breaks, massage therapists, acknowledgement from management and leadership within wards. The findings highlight the need to understand local perspectives and the importance of involving nurses in identifying initiatives to reduce occupational stress. Health-care environments can be enhanced through local understanding of the occupational stressors and productively engaging nurses in developing stress reduction initiatives. Nurse managers must facilitate such processes. © 2013 Blackwell Publishing Ltd.

Use of trunk stabilization and locomotor training in an adult with cerebellar ataxia: a single system design.

PubMed

Freund, Jane E; Stetts, Deborah M

2010-10-01

The purpose of this study is to describe the effects of trunk stabilization training and locomotor training (LT) using body-weight support on a treadmill (BWST) and overground walking on balance, gait, self-reported function, and trunk muscle performance in an adult with severe ataxia secondary to brain injury. There are no studies on the effectiveness of these combined interventions in persons with ataxia. The subject was a 23-year-old male who had a traumatic brain injury 13 months prior. An A-B-A withdrawal single-system design was used. Outcome measures were Berg Balance Test (BBT), timed unsupported stance, Functional Ambulation Category (FAC), 10-meter walk test (10-MWT), Outpatient Physical Therapy Improvement in Movement Assessment Log (OPTIMAL), transverse abdominis (TrA) thickness, and isometric trunk endurance tests. Performance on the BBT, timed unsupported stance, FAC, 10-MWT, and OPTIMAL each improved after 10 weeks of intervention. In additions, TrA symmetry at rest improved as did right side-bridge endurance time. LT, using BWST and overground walking, and trunk stabilization training may be effective in improving balance, gait, function, and trunk performance in individuals with severe ataxia. Further research with additional subjects is indicated.

The diversity issue revisited: international students in clinical environment.

PubMed

Pitkäjärvi, Marianne; Eriksson, Elina; Pitkälä, Kaisu

2012-01-01

Background. Globalization within higher education leads to an increase in cultural and linguistic diversity in student populations. The purpose of this study was to explore culturally diverse health care students' experiences in clinical environment in Finland, and to compare them with those of native Finnish students' participating in the same program. Method. A cross-sectional survey was performed at 10 polytechnic faculties of health care in Finland. 283 respondents (148 international and 95 Finnish students) responded to items concerning clinical rotation. The survey included items grouped as dimensions: (1) welcoming clinical environment, (2) unsupportive clinical environment, (3) approach to cultural diversity, (4) communication, and (5) structural arrangements. Results. International students felt as welcome on their placements as Finnish students. Concerning structural arrangements set up to facilitate preceptorship and approach to cultural diversity in the learning environment, the two groups' opinions were similar. However, international students were more likely than Finnish students to experience their clinical learning environment as unsupportive (P < 0.001). In addition, their experiences of communication with the staff was poorer than that of their Finnish peers' (P = 0.04). Conclusions. Awareness of strategies that enhance understanding, acceptance, and appreciation of cultural and linguistic diversity in any health care setting are needed.

Molecular Transport Studies Through Unsupported Lipid Membranes

NASA Astrophysics Data System (ADS)

Rock, William; Parekh, Sapun; Bonn, Mischa

2014-03-01

Dendrimers, spherical polymeric nanoparticles made from branched monomers around a central core, show great promise as drug delivery vehicles. Dendrimer size, core contents, and surface functionality can be synthetically tuned, providing unprecedented versatility. Polyamidoamine (PAMAM) dendrimers have been shown to enter cells; however, questions remain about their biophysical interactions with the cell membrane, specifically about the presence and size of transient pores. We monitor dendrimer-lipid bilayer interactions using unsupported black lipid membranes (BLMs) as model cell membranes. Custom bilayer slides contain two vertically stacked aqueous chambers separated by a 25 μm Teflon sheet with a 120 μm aperture where the bilayer is formed. We vary the composition of model membranes (cholesterol content and lipid phase) to create biomimetic systems and study the interaction of PAMAM G6 and G3 dendrimers with these bilayers. Dendrimers, dextran cargo, and bilayers are monitored and quantified using time-lapse fluorescence imaging. Electrical capacitance measurements are simultaneously recorded to determine if the membrane is porous, and the pore size is deduced by monitoring transport of fluorescent dextrans of increasing molecular weight. These experiments shed light on the importance of cholesterol content and lipid phase on the interaction of dendrimer nanoparticles with membranes.

Cation distribution and vacancies in nickel cobaltite.

PubMed

Loche, Danilo; Marras, Claudia; Carta, Daniela; Casula, Maria Francesca; Mountjoy, Gavin; Corrias, Anna

2017-06-28

Samples of nickel cobaltite, a mixed oxide occurring in the spinel structure which is currently extensively investigated because of its prospective application as ferromagnetic, electrocatalytic, and cost-effective energy storage material were prepared in the form of nanocrystals stabilized in a highly porous silica aerogel and as unsupported nanoparticles. Nickel cobaltite nanocrystals with average size 4 nm are successfully grown for the first time into the silica aerogel provided that a controlled oxidation of the metal precursor phases is carried out, consisting in a reduction under H 2 flow followed by mild oxidation in air. The investigation of the average oxidation state of the cations and of their distribution between the sites within the spinel structure, which is commonly described assuming the Ni cations are only located in the octahedral sites, has been carried out by X-ray absorption spectroscopy providing evidence for the first time that the unsupported nickel cobaltite sample has a Ni : Co molar ratio higher than the nominal ratio of 1 : 2 and a larger than expected average overall oxidation state of the cobalt and nickel cations. This is achieved retaining the spinel structure, which accommodates vacancies to counterbalance the variation in oxidation state.

South African mental health care service user views on priorities for supporting recovery: implications for policy and service development.

PubMed

Kleintjes, Sharon; Lund, Crick; Swartz, Leslie

2012-01-01

The paper documents the views of South African mental health care service users on policy directions and service developments that are required to support their recovery. Semi-structured interviews were conducted with forty service users and service user advocates. A framework analysis approach was used to analyse the qualitative data. Service user priorities included addressing stigma, discrimination and disempowerment, and the links between mental health and poverty. They suggested that these challenges be addressed through public awareness campaigns, legislative and policy reform for rights protection, development of a national lobby to advocate for changes, and user empowerment. Users suggested that empowerment can be facilitated through opportunities for improved social relatedness and equitable access to social and economic resources. This study suggests three strategies to bridge the gap between mental health care service users rights and needs on one hand, and unsupportive attitudes, policies and practices on the other. These are: giving priority to service user involvement in policy and service reform, creating empathic alliances to promote user priorities, and building enabling partnerships to effect these priorities.

Effective sterilization of reusable instruments contaminated by Creutzfeldt–Jakob disease in dental care is a crucial issue for public health. The present cross-sectional study investigated how the recommended procedures for sterilization were implemented by French dental practices in real-world settings. A sample of dental practices was selected in the French Rhône-Alpes region. Data were collected by a self-questionnaire in 2016. Sterilization procedures (n = 33) were classified into 4 groups: (1) Pre-sterilization cleaning of reusable instruments; (2) Biological verification of sterilization cycles—Monitoring steam sterilization procedures; (3) Autoclave performance and practitioner knowledge of autoclave use; (4) Monitoring and documentation of sterilization procedures—Tracking and tracing the instrumentation. Answers were provided per procedure, along with the global implementation of procedures within a group (over 80% correctly performed). Then it was verified how adherence to procedure groups varied with the size of the dental practice and the proportion of dental assistants within the team. Among the 179 questionnaires available for the analyses, adherence to the recommended procedures of sterilization noticeably varied between practices, from 20.7% to 82.6%. The median percentages of procedures correctly implemented per practice were 58.1%, 50.9%, 69.2% and 58.2%, in Groups 1, 2, 3 and 4, respectively (corresponding percentages for performing over 80% of the procedures in the group: 23.4%, 6.6%, 46.6% and 38.6%). Dental practices ≥ 3 dental units performed significantly better (>80%) procedures of Groups 2 and 4 (p = 0.01 and p = 0.002, respectively), while no other significant associations emerged. As a rule, practices complied poorly with the recommended procedures, despite partially improved results in bigger practices. Specific training regarding sterilization procedures and a better understanding of the reasons leading to their non-compliance are needed. PMID:29693615

Provision of specific dental procedures by general dentists in the National Dental Practice-Based Research Network: questionnaire findings.

PubMed

Gilbert, Gregg H; Gordan, Valeria V; Korelitz, James J; Fellows, Jeffrey L; Meyerowitz, Cyril; Oates, Thomas W; Rindal, D Brad; Gregory, Randall J

2015-01-22

Objectives were to: (1) determine whether and how often general dentists (GDs) provide specific dental procedures; and (2) test the hypothesis that provision is associated with key dentist, practice, and patient characteristics. GDs (n = 2,367) in the United States National Dental Practice-Based Research Network completed an Enrollment Questionnaire that included: (1) dentist; (2) practice; and (3) patient characteristics, and how commonly they provide each of 10 dental procedures. We determined how commonly procedures were provided and tested the hypothesis that provision was substantively related to the three sets of characteristics. Two procedure categories were classified as "uncommon" (orthodontics, periodontal surgery), three were "common" (molar endodontics; implants; non-surgical periodontics), and five were "very common" (restorative; esthetic procedures; extractions; removable prosthetics; non-molar endodontics). Dentist, practice, and patient characteristics were substantively related to procedure provision; several characteristics seemed to have pervasive effects, such as dentist gender, training after dental school, full-time/part-time status, private practice vs. institutional practice, presence of a specialist in the same practice, and insurance status of patients. As a group, GDs provide a comprehensive range of procedures. However, provision by individual dentists is substantively related to certain dentist, practice, and patient characteristics. A large number and broad range of factors seem to influence which procedures GDs provide. This may have implications for how GDs respond to the ever-changing landscape of dental care utilization, patient population demography, scope of practice, delivery models and GDs' evolving role in primary care.

Surgical specialty procedures in rural surgery practices: implications for rural surgery training.

PubMed

Sticca, Robert P; Mullin, Brady C; Harris, Joel D; Hosford, Clint C

2012-12-01

Specialty procedures constitute one eighth of rural surgery practice. Currently, general surgeons intending to practice in rural hospitals may not get adequate training for specialty procedures, which they will be expected to perform. Better definition of these procedures will help guide rural surgery training. Current Procedural Terminology codes for all surgical procedures for 81% of North Dakota and South Dakota rural surgeons were entered into the Dakota Database for Rural Surgery. Specialty procedures were analyzed and compared with the Surgical Council on Resident Education curriculum to determine whether general surgery training is adequate preparation for rural surgery practice. The Dakota Database for Rural Surgery included 46,052 procedures, of which 5,666 (12.3%) were specialty procedures. Highest volume specialty categories included vascular, obstetrics and gynecology, orthopedics, cardiothoracic, urology, and otolaryngology. Common procedures in cardiothoracic and vascular surgery are taught in general surgical residency, while common procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology are usually not taught in general surgery training. Optimal training for rural surgery practice should include experience in specialty procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology. Copyright © 2012 Elsevier Inc.

His prudential critique rests on a massively oversimplified and somewhat offensive view of the causes of poverty. His moral premise is unsupported, and inconsistent with his demand for a state-funded investment in education. His article provides an excellent illustration of the anti-realist and Utopian nature of the ideology of the new right.

Dreaming is not controlled by hippocampal mechanisms.

Solms, Mark

2013-12-01

Links with the Humanities are to be welcomed, but they cannot be exempted from normal scientific criteria. Any hypothesis regarding the function of dreams that is premised on rapid eye movement (REM)/dream isomorphism is unsupportable on empirical grounds. Llewellyn's hypothesis has the further problem of counter-evidence in respect of its claim that dreaming relies upon hippocampal functions. The hypothesis also lacks face validity.

Validity and ethics of penile circumference measures of sexual arousal: a critical review.

PubMed

McConaghy, N

1989-08-01

Wheeler and Rubin (1987) advanced evidence that penile volume responses (PVRs) were no more sensitive than penile circumference responses (PCRs) in measuring erection which the authors incorrectly identified with sexual arousal. Knowledge of the literature would have led them to question that identification and the methodology of their study. PVRs have repeatedly been demonstrated to assess validly not erection but the sexual orientation of individuals, when derived from the early stage of erectile response to brief stimuli that were from their onset of moderate erotic strength. PCR assessment has been of the degree of erection to stimuli of 2-10 min duration. No success has been reported using PCR measures of erection to classify subjects individually as to their sexual orientation. Classification of groups of 30 but not 6 homosexuals was successful using their PCRs to nudes. Attempts to identify rapists and pedophiles from normals, and aggressive from nonaggressive rapists and pedophiles by PCRs have failed to be replicated. In comparing PVRs and PCRs, Wheeler and Rubin used as stimuli three 10-min presentations of a film which apparently did not immediately introduce erotic material. This procedure would not elicit meaningful PVRs. Though never validated as a measure of individuals' sexual arousal, PCR measures of erection are currently widely recommended for assessment and determining treatment of individual sex offenders. If these assessments could affect or are believed by the offenders to affect the outcome of the legal processes in which they are involved, the procedure is not only scientifically unsupported, it is unethical.

Ahmed, Nesreen S.; Surface Chemistry and Catalytic Studies Group, King Abdulaziz University; Menzel, Robert

Two efficient catalyst based on CuAl and CoAl layered double hydroxides (LDHs) supported on graphene oxide (GO) for the carbon-carbon coupling (Classic Ullmann Homocoupling Reaction) are reported. The pure and hybrid materials were synthesised by direct precipitation of the LDH nanoparticles onto GO, followed by a chemical, structural and physical characterisation by electron microscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), surface area measurements and X-ray photoelectron spectroscopy (XPS). The GO-supported and unsupported CuAl-LDH and CoAl-LDH hybrids were tested over the Classic Ullman Homocoupling Reaction of iodobenzene. In the current study CuAl- and CoAl-LDHs have shown excellent yields (91% and 98%,more » respectively) at very short reaction times (25 min). GO provides a light-weight, charge complementary and two-dimensional material that interacts effectively with the 2D LDHs, in turn enhancing the stability of LDH. After 5 re-use cycles, the catalytic activity of the LDH/GO hybrid is up to 2 times higher than for the unsupported LDH. - Graphical abstract: CuAl- and CoAl-LDHs have shown excellent yields (91% and 98%, respectively) at very short reaction times (25 min).

Slum dwellers display specific traits when it comes to disclosing their illnesses to professionals. The resulting actions lead to poor health-seeking behaviour and underutilisation of existing formal health facilities. The ways that slum people use to communicate their feelings about illness, the type of confidants that they choose, and the supportive and unsupportive social and cultural interactions to which they are exposed have not yet been studied in the Indian context, which constitutes an important knowledge gap for Indian policymakers and practitioners alike. To that end, this study examines the patterns of illness disclosure in Indian slums and the underpinning factors which shape the slum dwellers' disclosing attitude. In-depth, semi-structured interviews were conducted among 105 men and 113 women who experienced illness in the year prior to the study period. Respondents were selected from four urban slums in two Indian cities, Bangalore and Kolkata. Findings indicate that women have more confidants at different social levels, while men have a limited network of disclosures which is culturally and socially mediated. Gender role limitations, exclusion from peer groups and unsupportive local situations are the major cause of disclosure delay or non-disclosure among men, while the main concerns for women are a lack of proper knowledge about illness, unsupportive responses received from other people on certain occasions, the fear of social stigma, material loss and the burden of the local situation. Prompt sharing of illness among men is linked with prevention intention and coping with biological problems, whereas factors determining disclosure for women relate to ensuring emotional and instrumental safety, preventing collateral damage of illness, and preventing and managing biological complications. The findings reveal that patterns of disclosure are not determined by the acknowledgment of illness but largely depend on the interplay between individual agency, disclosure consequences and the socio cultural environment. The results of this study can contribute significantly to mitigating the pivotal knowledge gap between health policymakers, practitioners and patients, leading to the formulation of policies that maximise the utilisation of health facilities in slums.

Does general surgery residency prepare surgeons for community practice in British Columbia?

PubMed Central

Hwang, Hamish

2009-01-01

Background Preparing surgeons for clinical practice is a challenging task for postgraduate training programs across Canada. The purpose of this study was to examine whether a single surgeon entering practice was adequately prepared by comparing the type and volume of surgical procedures experienced in the last 3 years of training with that in the first year of clinical practice. Methods During the last 3 years of general surgery training, I logged all procedures. In practice, the Medical Services Plan (MSP) of British Columbia tracks all procedures. Using MSP remittance reports, I compiled the procedures performed in my first year of practice. I totaled the number of procedures and broke them down into categories (general, colorectal, laparoscopic, endoscopic, hepatobiliary, oncologic, pediatric, thoracic, vascular and other). I then compared residency training with community practice. Results I logged a total of 1170 procedures in the last 3 years of residency. Of these, 452 were performed during community rotations. The procedures during residency could be broken down as follows: 392 general, 18 colorectal, 242 laparoscopic, 103 endoscopic, 85 hepatobiliary, 142 oncologic, 1 pediatric, 78 thoracic, 92 vascular and 17 other. I performed a total of 1440 procedures in the first year of practice. In practice the break down was 398 general, 15 colorectal, 101 laparoscopic, 654 endoscopic, 2 hepatobiliary, 77 oncologic, 10 pediatric, 0 thoracic, 70 vascular and 113 other. Conclusion On the whole, residency provided excellent preparation for clinical practice based on my experience. Areas of potential improvement included endoscopy, pediatric surgery and “other,” which comprised mostly hand surgery. PMID:19503663

Do procedural skills workshops during family practice residency work?

To determine if participation in a procedural skills workshop during family practice residency affects future use of these skills in postgraduate clinical practice. Survey involving self-assessment of procedural skills experience and competence. British Columbia. Former University of British Columbia family practice residents who trained in Vancouver, BC, including residents who participated in a procedural skills workshop in 2001 or 2003 and residents graduating in 2000 and 2002 who did not participate in the procedural skills workshop. Self-assessed experience and competence in the 6 office-based procedural skills that were taught during the procedural skills workshops in 2001 and 2003. Participation in a procedural skills workshop had no positive effect on future use of these skills in clinical practice. Participation in the workshop was associated with less reported experience (P = .091) in injection of lateral epicondylitis. As with previous Canadian studies, more women than men reported experience and competence in gynecologic procedures. More women than men reported experience (P = .001) and competence (P = .004) in intrauterine device insertion and experience (P = .091) in endometrial aspiration biopsy. More men than women reported competence (P = .052) in injection of trochanteric bursae. A third year of emergency training was correlated with an increase in reported experience (P = .021) in shoulder injection. Participation in a procedural skills workshop during family practice residency did not produce a significant increase in the performance of these skills on the part of participants once they were in clinical practice. The benefit of a skills workshop might be lost when there is no opportunity to practise and perfect these skills. Sex bias in the case of some procedures might represent a needs-based acquisition of skills on the part of practising physicians. Short procedural skills workshops might be better suited to graduated physicians with more clinical experience.

Competency-based medical education: the discourse of infallibility.

2018-01-01

Over the last two decades, competency-based frameworks have been internationally adopted as the primary educational approach in medicine. Yet competency-based medical education (CBME) remains contested in the academic literature. We look broadly at the nature of this debate to explore how it may shape scholars' understanding of CBME, and its implications for medical education research and practice. In doing so, we deconstruct unarticulated discourses and assumptions embedded in the CBME literature. We assembled an archive of literature focused on CBME. The archive dates from 1996, the publication year of the first CanMEDS Physician Competency Framework. We then conducted a Foucauldian critical discourse analysis (CDA) to delineate the dominant discourses underpinning the literature. CDA examines the intersections of language, social practices, knowledge and power relations to highlight how entrenched ways of thinking influence what can or cannot be said about a topic. Detractors of CBME have advanced an array of conceptual critiques. Proponents have often responded with a recurring discursive strategy that minimises these critiques and deflects attention from the underlying concept of the competency-based approach. As part of this process, conceptual concerns are reframed as two practical problems: implementation and interpretation. Yet the assertion that these are the construct's primary concerns was often unsupported by empirical evidence. These practices contribute to a discourse of infallibility of CBME. In uncovering the discourse of infallibility, we explore how it can silence critical voices and hinder a rigorous examination of the competency-based approach. These discursive practices strengthen CBME by constructing it as infallible in the literature. We propose re-approaching the dialogue surrounding CBME as a starting point for empirical investigation, driven by the aim to broaden scholars' understanding of its design, development and implementation in medical education. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Classroom implementation of the practices learned in the Master of Chemistry Education program by the School District of Philadelphia's high school chemistry teachers

NASA Astrophysics Data System (ADS)

Jayaraman, Uma Devi

This dissertation reports the results of an exploratory case study utilizing quantitative and qualitative methodologies intended to ascertain the extent and differences of implementation of research-based instructional practices, learned in an intensive 26-month professional development, in their urban classrooms. Both the extent and differences in the implementation of practices were investigated in relation to the lesson design and implementation, content, and classroom culture aspects of research-based practices. Additionally, this research includes the concerns of the teachers regarding the factors that helped or hindered the implementation of research-based practices in their classrooms. Six graduates of the Master of Chemistry Education Program who were teaching a chemistry course in a high school in the School District of Philadelphia at the time of the study (2006-8), were the case. The teachers completed a concerns questionnaire with closed and open-ended items, and rated their perceptions of the extent of implementation of the practices in their urban classrooms. Additionally, the teachers were observed and rated by the researcher using a reform-teaching observation protocol and were interviewed individually. Also, the teachers submitted their lesson plans for the days they were observed. Data from these sources were analyzed to arrive at the findings for this study. The research findings suggest that the group of teachers in the study implemented the research-based practices in their classrooms to a low extent when compared to the recommended practices inherent to the MCE Program. The extents of implementation of the practices differed widely among the teachers, from being absent to being implemented at a high level, with inconsistent levels of implementation from various data sources. Further, the teachers expressed the depth of knowledge (gained in the MCE Program), formal laboratory exercises and reports, administrative support, self-motivated students, and group/collaborative work as several factors that enabled or would have enabled the implementation of practices. Among the many factors that hindered the implementation of the practices in their urban classrooms were, the core curriculum and pacing schedule, followed by test preparation, administrative paper-work, large class-size, students not prepared for student-centered work, poor math and reading skills of students, students' lack of motivation, unsupportive department head, unresponsive administration, and lack of resources.

Acquisition of competency in procedural skills is a fundamental goal of medical training. In this Perspective, the authors propose an evidence-based pedagogical framework for procedural skill training. The framework was developed based on a review of the literature using a critical synthesis approach and builds on earlier models of procedural skill training in medicine. The authors begin by describing the fundamentals of procedural skill development. Then, a six-step pedagogical framework for procedural skills training is presented: Learn, See, Practice, Prove, Do, and Maintain. In this framework, procedural skill training begins with the learner acquiring requisite cognitive knowledge through didactic education (Learn) and observation of the procedure (See). The learner then progresses to the stage of psychomotor skill acquisition and is allowed to deliberately practice the procedure on a simulator (Practice). Simulation-based mastery learning is employed to allow the trainee to prove competency prior to performing the procedure on a patient (Prove). Once competency is demonstrated on a simulator, the trainee is allowed to perform the procedure on patients with direct supervision, until he or she can be entrusted to perform the procedure independently (Do). Maintenance of the skill is ensured through continued clinical practice, supplemented by simulation-based training as needed (Maintain). Evidence in support of each component of the framework is presented. Implementation of the proposed framework presents a paradigm shift in procedural skill training. However, the authors believe that adoption of the framework will improve procedural skill training and patient safety.

A catalyst is described for the synthesis of hydrocarbons from CO+H.sub.2 utilizing a porous Al.sub.2 O.sub.3 support impregnated with iron and copper and optionally promoted with an alkali metal. The use of an Al.sub.2 O.sub.3 support results in the suppression of heavy waxes (C.sub.26 + hydrocarbons), particularly in slurry phase operation, when compared to unsupported or co-precipitated catalysts.

Background Homeless youth are the fastest growing sub-group within the homeless population. They face impaired access to health services and are often left unsupported. They lack social and family support or relationships with service providers. Unsupported homeless youth often become homeless adults. Purpose To test a model based on Peplau's Theory of Interpersonal Relations, examining the influence of a network of service providers, perceptions of social supports, and family relations on a homeless youth's perceptions of recovery. Methods This study is a secondary analysis and used a sample (n = 187) of data collected as part of the original Youth Matters in London study. A cross-sectional design was used to analyze the relationship between variables. Participants were interviewed at 6-month intervals over a 2.5-year period. Hierarchical multiple regression analysis was used. Results Network of service providers, perceived social supports, and perceived family relations explained 21.8% of the variance in homeless youth perceptions of recovery. Perceived social support and family relations were significantly, positively correlated to perceptions of recovery. Network of service providers was not significantly correlated to perceptions of recovery. Conclusions The findings suggest that stronger social supports and family relations may contribute to increased perceptions of recovery among homeless youth.

Sediment data for computations of deposition rates in the tidal Potomac system, Maryland and Virginia

Sixty-two cores ranging in length from 33 to 1,002 cm were collected from the tidal Potomac system and from selected tributaries downstream from the local head-of-tides between June 1978 and July 1981. Segments from selected depths below the sediment surface have been analyzed for a variety of constituents, including lead-210, trace metals, nutrients, and particle size. The core sites were positioned throughout the hydrologic divisions and geomorphic units of the tidal Potomac system and in water depths ranging from 1 to 30 cm. Alpha counting methods were used to determine the polonium-210 radioactivity and secular equilibrium was assumed between lead-210more » and polonium-210. The alpha decay of polonium-210 provides a measure of the lead-210 radioactivity of the lead-210 produced by in-situ decay of radium-226 in the sediment column and the lead-210 from external sources. Only the unsupported lead-210 was used in computations of the deposition rate. The background level of lead-210 in tidal Potomac system sediment cores usually is based on in-situ measurements of total lead-210 at depths below which no unsupported lead-210 is believed to be present, and the lead-210 concentrations are relatively constant. 6 refs., 3 figs., 1 tab.« less

Synthesis of Unsupported d(1)-d(x) Oxido-Bridged Heterobimetallic Complexes Containing V(IV): A New Direction for Metal-to-Metal Charge Transfer.

Heterobimetallic complexes composed only of first-row transition metals [(TMTAA)V(IV)═O→M(II)Py5Me2](OTf)2 (TMTAA = 7,16-dihydro-6,8,15,17-tetramethyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine; Py5Me2 = 2,6-bis(1,1-bis(2-pyridyl)ethyl)pyridine; M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II); OTf = trifluoromethanesulfonate) have been synthesized through a dative interaction between a terminal oxido and M(II) metal centers. This is the first series of V(IV)═O→M(II) heterobimetallic complexes containing an unsupported oxido bridge. Among these five complexes, only V(IV)═O→Fe(II) (3b) has a clear new absorption band upon formation of the dinuclear species (502 nm, ε = 1700 M(-1) cm(-1)). This feature is assigned to a metal-to-metal charge transfer (MMCT) transition from V(IV) to Fe(II), which forms a V(V)-O-Fe(I) excited state. This assignment is supported by electrochemical data, electronic absorption profiles, and resonance Raman spectroscopy and represents the first report of visible-light induced MMCT in a heterobimetallic oxido-bridged molecule where the electron originates on a d(1) metal center.

Influence of gravity compensation training on synergistic movement patterns of the upper extremity after stroke, a pilot study

PubMed Central

2012-01-01

Background The majority of stroke patients have to cope with impaired arm function. Gravity compensation of the arm instantaneously affects abnormal synergistic movement patterns. The goal of the present study is to examine whether gravity compensated training improves unsupported arm function. Methods Seven chronic stroke patients received 18 half-hour sessions of gravity compensated reach training, in a period of six weeks. During training a motivating computer game was played. Before and after training arm function was assessed with the Fugl-Meyer assessment and a standardized, unsupported circle drawing task. Synergistic movement patterns were identified based on concurrent changes in shoulder elevation and elbow flexion/extension angles. Results Median increase of Fugl-Meyer scores was 3 points after training. The training led to significantly increased work area of the hemiparetic arm, as indicated by the normalized circle area. Roundness of the drawn circles and the occurrence of synergistic movement patterns remained similar after the training. Conclusions A decreased strength of involuntary coupling might contribute to the increased arm function after training. More research is needed to study working mechanisms involved in post stroke rehabilitation training. The used training setup is simple and affordable and is therefore suitable to use in clinical settings. PMID:22824488

2009-11-01

Night-time postural equipment (NTPE) prevents contractures and hip subluxation in children with severe physical disabilities. However, impact on sleep quality and respiratory function has not been objectively studied. Ten children with severe cerebral palsy (CP), mean age of 10.9 (range: 5.3-16.7) years, were recruited from a community population. Polysomnography was undertaken on two nights, once with the child sleeping in their NTPE and once sleeping unsupported. Randomization to first night condition controlled for first night effects. Night-time postural equipment use was associated with higher mean overnight oxygen saturation for three children but lower values for six children compared with sleeping unsupported. There were no differences in sleep quality between the conditions. The study group had lower overnight oxyhaemoglobin saturation values, less rapid eye movement (REM) sleep and higher arousal indices compared with typically developing children. This pilot study indicated that children with severe CP risk respiratory compromise in sleep irrespective of positioning. Further study will determine if the observed trend for mean overnight oxygen saturation to be lower within positioning equipment reflects random night-to-night variation or is related to equipment use. We suggest that respiratory function is assessed when determining optimal positioning for children using night-time positioning equipment.

Measuring mechanodynamics in an unsupported epithelial monolayer grown at an air–water interface

Actomyosin contraction and relaxation in a monolayer is a fundamental biophysical process in development and homeostasis. Current methods used to characterize the mechanodynamics of monolayers often involve cells grown on solid supports such as glass or gels. The results of these studies are fundamentally influenced by these supporting structures. Here we describe a new method for measuring the mechanodynamics of epithelial monolayers by culturing cells at an air–liquid interface. These model monolayers are grown in the absence of any supporting structures, removing cell–substrate effects. This method’s potential was evaluated by observing and quantifying the generation and release of internal stresses upon actomyosin contraction (800 ± 100 Pa) and relaxation (600 ± 100 Pa) in response to chemical treatments. Although unsupported monolayers exhibited clear major and minor strain axes, they were not correlated with nuclear alignment as observed when the monolayers were grown on soft deformable gels. It was also observed that both gels and glass substrates led to the promotion of long-range cell nuclei alignment not seen in the hanging-drop model. This new approach provides us with a picture of basal actomyosin mechanodynamics in a simplified system, allowing us to infer how the presence of a substrate affects contractility and long-range multicellular organization and dynamics.

Effective in situ remediation of Cr(VI) in groundwater requires the successful delivery of reactive iron particles to the subsurface. Fe(0) nanoparticles (20-110 nm diameter) supported on silica fume were synthesized by borohydride reduction of an aqueous iron salt in the presence of a support material. The experimental result showed that attachment of Fe(0) nanoparticles on the commercial available sub-micrometer silica fume prevented them from aggregation while maintaining the particle reactivity. When the Fe(0) concentration was 0.4 g/L, 88.00% of 40 mg/L Cr(VI) was removed by silica fume-supported Fe(0) nanoparticles (SF-Fe(0) in 120 min, 22.55% higher than unsupported Fe(0). Furthermore, transport experiments confirmed that almost all unsupported Fe(0) was retained, whereas 51.50% and 38.29% of SF-Fe(0) were eluted from the vertical and horizontal sand column, respectively. Additionally, the effect of solution ionic strength on the transport ability of SF-Fe(0) was evaluated. The result showed that increase in the salt concentration led to a decrease in the mobility and also the divalent ion Ca2+ had a greater effect than that of monovalent ion Na+.

Views of young people with depression about family and significant other support: interpretative phenomenological analysis study.

Families and significant others have an important role in helping young people cope with depression, but lack of support undermines coping. In this paper, we present the views of young people with depression about the role of family and significant others in assisting them to cope with their illness. An interpretative phenomenological analysis study was undertaken using semistructured, audio-recorded interviews with 26 young people diagnosed with depression. The findings present two contrasting themes in the data, which reflect the young people's views about the influence of families and significant others in helping them cope with depression. The first, being supportive, highlighted how families and significant others helped through patience, tolerance, understanding, and encouragement; all of which strengthened young people's resilience as they attempted to cope with depression. The second theme, being unsupportive, showed how, in the young people's view, family conflict and change, and living in an unsupportive environment, compromised their ability to cope with depression. The findings suggest that mental health nurses, other clinicians, and primary care practitioners need to increase families' and significant others' understandings of depression and their capacity to support young people in these circumstances. © 2012 The Authors.

Prophylactic ankle bracing is commonly used during physical activity. Understanding how bracing affects body mechanics is critically important when discussing both injury prevention and sport performance. The purpose is to determine if ankle bracing affects lower extremity mechanics during the Landing Error Scoring System test (LESS) and Sage Sway Index (SSI). Thirty physically active participants volunteered for this study. Participants completed the LESS and SSI in both a braced and unsupported conditions. Total errors were recorded for the LESS. Total errors and time (seconds) were recorded for the SSI. The Wilcoxon signed-rank test was utilized to evaluate any differences between the brace conditions for each dependent variable. A priori alpha level was set at p<0.05. The Wilcoxon signed-rank test yielded no significant difference between the braced and unsupported conditions for the LESS (Z=-0.35, p=0.72), SSI time (Z=-0.36, p=0.72), or SSI Errors (Z=-0.37, p=0.71). Ankle braces had no effect on subjective clinical assessments of lower extremity alignment or postural stability. Utilization of a prophylactic support at the ankle did not substantially alter the proximal components of the lower kinetic chain. © Georg Thieme Verlag KG Stuttgart · New York.

Five solar geoengineering tropes that have outstayed their welcome

Reynolds, Jesse L.; Parker, Andy; Irvine, Peter

2016-12-01

In the last decade, solar geoengineering (solar radiation management, or SRM) has received increasing consideration as a potential means to reduce risks of anthropogenic climate change. Some ideas regarding SRM that have been proposed have receded after being appropriately scrutinized, while others have strengthened through testing and critique. This process has improved the understanding of SRM's potential and limitations. However, several claims are frequently made in the academic and popular SRM discourses and, despite evidence to the contrary, pose the risk of hardening into accepted facts. Here, in order to foster a more productive and honest debate, we identify, describe, and refute five of the most problematic claims that are unsupported by existing evidence, unlikely to occur, or greatly exaggerated. These are: (A) once started, SRM cannot be stopped; (B) SRM is a right-wing project; (C) SRM would cost only a few billion dollars per year; (D) modeling studies indicate that SRM would disrupt monsoon precipitation; and (E) there is an international prohibition on outdoors research. SRM is a controversial proposed set of technologies that could prove to be very helpful or very harmful, and it warrants vigorous and informed public debate. By highlighting and debunking some persistent but unsupported claims, this paper hopes to bring rigor to such discussions.

Dyssynchronous breathing during arm but not leg exercise in patients with chronic airflow obstruction.

PubMed

Celli, B R; Rassulo, J; Make, B J

1986-06-05

Some patients with chronic airflow obstruction experience dyspnea with mild arm exercise but not with more-intense leg exercise. To investigate why these patients have limited endurance during arm exertion, we studied ventilatory responses to exercise with unsupported arms in 12 patients with chronic airflow obstruction (mean [+/- SD] forced expiratory volume in one second, 0.68 +/- 0.28 liters). Unloaded leg cycling was also studied for comparison. In the five patients who had the most severe airflow obstruction, arm exercise was limited by dyspnea after 3.3 +/- 0.7 minutes, and dyssynchronous thoracoabdominal breathing developed. In the other seven patients, arm exercise was limited by the sensation of muscle fatigue after 6.1 +/- 2.0 minutes (P less than 0.05), and dyssynchronous breathing did not occur. None of the 12 patients had dyssynchronous breathing during unloaded leg cycling. Maximal transdiaphragmatic pressure, a measure of diaphragmatic fatigue, declined similarly after arm and leg exercise in both groups. During unsupported arm work, the accessory muscles of inspiration help position the torso and arms. We hypothesize that the extra demand placed on these muscles during arm exertion leads to early fatigue, an increased load on the diaphragm, and dyssynchronous thoracoabdominal inspirations. This sequence may contribute to dyspnea and limited endurance during upper-extremity exercise.

Leaf mimicry in a climbing plant protects against herbivory.

PubMed

Gianoli, Ernesto; Carrasco-Urra, Fernando

2014-05-05

Mimicry refers to adaptive similarity between a mimic organism and a model. Mimicry in animals is rather common, whereas documented cases in plants are rare, and the associated benefits are seldom elucidated [1, 2]. We show the occurrence of leaf mimicry in a climbing plant endemic to a temperate rainforest. The woody vine Boquila trifoliolata mimics the leaves of its supporting trees in terms of size, shape, color, orientation, petiole length, and/or tip spininess. Moreover, sequential leaf mimicry occurs when a single individual vine is associated with different tree species. Leaves of unsupported vines differed from leaves of climbing plants closely associated with tree foliage but did not differ from those of vines climbing onto leafless trunks. Consistent with an herbivory-avoidance hypothesis, leaf herbivory on unsupported vines was greater than that on vines climbing on trees but was greatest on vines climbing onto leafless trunks. Thus, B. trifoliolata gains protection against herbivory not merely by climbing and thus avoiding ground herbivores [3] but also by climbing onto trees whose leaves are mimicked. Unlike earlier cases of plant mimicry or crypsis, in which the plant roughly resembles a background or color pattern [4-7] or mimics a single host [8, 9], B. trifoliolata is able to mimic several hosts.

Objectives To examine doctors' experiences of complaints, including which aspects are most stressful. We also investigated how doctors felt complaints processes could be improved. Design and methods A qualitative study based on a cross-sectional survey of members of the British Medical Association (BMA). We asked the following: (1) Try to summarise as best as you can your experience of the complaints process and how it made you feel. (2) What were the most stressful aspects of the complaint? (3) What would you improve in the complaints system? Participants We sent the survey to 95 636 doctors, and received 10 930 (11.4%) responses. Of these, 6146 had a previous, recent or current complaint and 3417 (31.3%) of these respondents answered questions 1 and 2. We randomly selected 1000 answers for analysis, and included 100 using the saturation principle. Of this cohort, 93 responses for question 3 were available. Main results Doctors frequently reported feeling powerless, emotionally distressed, and experiencing negative feelings towards both those managing complaints and the complainants themselves. Many felt unsupported, fearful of the consequences and that the complaint was unfair. The most stressful aspects were the prolonged duration and unpredictability of procedures, managerial incompetence, poor communication and perceiving that processes are biased in favour of complainants. Many reported practising defensively or considering changing career after a complaint, and few found any positive outcomes from complaints investigations. Physicians suggested procedures should be more transparent, competently managed, time limited, and that there should be an open dialogue with complainants and policies for dealing with vexatious complaints. Some felt more support for doctors was needed. Conclusions Complaints seriously impact on doctors' psychological wellbeing, and are associated with defensive practise. This is not beneficial to patient care. To improve procedures, doctors propose they are simplified, time limited and more transparent. PMID:27377638

Atomic-Scale Design of Iron Fischer-Tropsch Catalysts: A Combined Computational Chemistry, Experimental, and Microkinetic Modeling Approach

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

Manos Mavrikakis; James A. Dumesic; Rahul P. Nabar

2006-09-29

Work continued on the development of a microkinetic model of Fischer-Tropsch synthesis (FTS) on supported and unsupported Fe catalysts. The following aspects of the FT mechanism on unsupported iron catalysts were investigated on during this third year: (1) the collection of rate data in a Berty CSTR reactor based on sequential design of experiments; (2) CO adsorption and CO-TPD for obtaining the heat of adsorption of CO on polycrystalline iron; and (3) isothermal hydrogenation (IH) after Fischer Tropsch reaction to identify and quantify surface carbonaceous species. Rates of C{sub 2+} formation on unsupported iron catalysts at 220 C and 20more » atm correlated well to a Langmuir-Hinshelwood type expression, derived assuming carbon hydrogenation to CH and OH recombination to water to be rate-determining steps. From desorption of molecularly adsorbed CO at different temperatures the heat of adsorption of CO on polycrystalline iron was determined to be 100 kJ/mol. Amounts and types of carbonaceous species formed after FT reaction for 5-10 minutes at 150, 175, 200 and 285 C vary significantly with temperature. Mr. Brian Critchfield completed his M.S. thesis work on a statistically designed study of the kinetics of FTS on 20% Fe/alumina. Preparation of a paper describing this work is in progress. Results of these studies were reported at the Annual Meeting of the Western States Catalysis and at the San Francisco AIChE meeting. In the coming period, studies will focus on quantitative determination of the rates of kinetically-relevant elementary steps on unsupported Fe catalysts with/without K and Pt promoters by SSITKA method. This study will help us to (1) understand effects of promoter and support on elementary kinetic parameters and (2) build a microkinetics model for FTS on iron. Calculations using periodic, self-consistent Density Functional Theory (DFT) methods were performed on models of defected Fe surfaces, most significantly the stepped Fe(211) surface. Binding Energies (BE's), preferred adsorption sites and geometries of all the FTS relevant stable species and intermediates were evaluated. Each elementary step of our reaction model was fully characterized with respect to its thermochemistry and comparisons between the stepped Fe(211) facet and the most-stable Fe(110) facet were established. In most cases the BE's on Fe(211) reflected the trends observed earlier on Fe(110), yet there were significant variations imposed on the underlying trends. Vibrational frequencies were evaluated for the preferred adsorption configurations of each species with the aim of evaluating the entropy-changes and preexponential factors for each elementary step. Kinetic studies were performed for the early steps of FTS (up to CH{sub 4} formation) and CO dissociation. This involved evaluation of the Minimum Energy Pathway (MEP) and activation energy barrier for the steps involved. We concluded that Fe(211) would allow for far more facile CO dissociation in comparison to other Fe catalysts studied so far, but the other FTS steps studied remained mostly unchanged.« less

Do procedural skills workshops during family practice residency work?

PubMed Central

MacKenzie, Mark S.; Berkowitz, Jonathan

2010-01-01

ABSTRACT OBJECTIVE To determine if participation in a procedural skills workshop during family practice residency affects future use of these skills in postgraduate clinical practice. DESIGN Survey involving self-assessment of procedural skills experience and competence. SETTING British Columbia. PARTICIPANTS Former University of British Columbia family practice residents who trained in Vancouver, BC, including residents who participated in a procedural skills workshop in 2001 or 2003 and residents graduating in 2000 and 2002 who did not participate in the procedural skills workshop. MAIN OUTCOME MEASURES Self-assessed experience and competence in the 6 office-based procedural skills that were taught during the procedural skills workshops in 2001 and 2003. RESULTS Participation in a procedural skills workshop had no positive effect on future use of these skills in clinical practice. Participation in the workshop was associated with less reported experience (P = .091) in injection of lateral epicondylitis. As with previous Canadian studies, more women than men reported experience and competence in gynecologic procedures. More women than men reported experience (P = .001) and competence (P = .004) in intrauterine device insertion and experience (P = .091) in endometrial aspiration biopsy. More men than women reported competence (P = .052) in injection of trochanteric bursae. A third year of emergency training was correlated with an increase in reported experience (P = .021) in shoulder injection. CONCLUSION Participation in a procedural skills workshop during family practice residency did not produce a significant increase in the performance of these skills on the part of participants once they were in clinical practice. The benefit of a skills workshop might be lost when there is no opportunity to practise and perfect these skills. Sex bias in the case of some procedures might represent a needs-based acquisition of skills on the part of practising physicians. Short procedural skills workshops might be better suited to graduated physicians with more clinical experience. PMID:20705868

A Case Study of a High School Fab Lab

NASA Astrophysics Data System (ADS)

Lacy, Jennifer E.

This dissertation examines making and design-based STEM education in a formal makerspace. It focuses on how the design and implementation of a Fab Lab learning environment and curriculum affect how instructors and students see themselves engaging in science, and how the Fab Lab relates to the social sorting practices that already take place at North High School. While there is research examining design-based STEM education in informal and formal learning environments, we know little about how K-12 teachers define STEM in making activities when no university or museum partnership exists. This study sought to help fill this gap in the research literature. This case study of a formal makerspace followed instructors and students in one introductory Fab Lab course for one semester. Additional observations of an introductory woodworking course helped build the case and set it into the school context, and provided supplementary material to better understand the similarities and differences between the Fab Lab course and a more traditional design-based learning course. Using evidence from observational field notes, participant interviews, course materials, and student work, I found that the North Fab Lab relies on artifacts and rhetoric symbolic of science and STEM to set itself apart from other design-based courses at North High School. Secondly, the North Fab Lab instructors and students were unable to explain how what they were doing in the Fab Lab was science, and instead relied on vague and unsupported claims related to interdisciplinary STEM practices and dated descriptions of science. Lastly, the design and implementation of the Fab Lab learning environment and curriculum and its separation from North High School's low tech, design-based courses effectively reinforced social sorting practices and cultural assumptions about student work and intelligence.

(18)O(2) label mechanism of sulfur generation and characterization in properties over mesoporous Sm-based sorbents for hot coal gas desulfurization.

Using a sol-gel method, SmMeOx/MCM-41 or SBA-15 (Me=Fe, Co and Zn) and corresponding unsupported sorbents were prepared. The desulfurization performance of these sorbents was evaluated over a fixed-bed reactor and the effects of reaction temperature, feed and sorbent composition on desulfurization performance were studied. Samarium-based sorbents used to remove H2S from hot coal gas were reported for the first time. The results of successive sulfidation/regeneration cycles revealed that SmFeO3/SBA-15 sorbent was suitable for desulfurization of hot coal gas in the chemical industry. The formation of elemental sulfur during both sulfidation and regeneration processes depended strongly on the catalytic action of Sm2O2S species, which was confirmed for the first time via high sensitive time of flight mass spectrometer (TOF-MS) using 6%vol(18)O2/Ar regeneration gas and can reduce markedly procedural complexity. The sorbents were characterized using N2-adsorption, high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), temperature-programmed reduction of H2 (H2-TPR), thermogravimetry (TG) and time-of-flight mass spectrometry (TOF-MS) techniques.

Adaptive changes in anticipatory postural adjustments with novel and familiar postural supports.

Hall, Leanne M; Brauer, Sandra; Horak, Fay; Hodges, Paul W

2010-02-01

Anticipatory postural adjustments (APAs) serve to stabilize posture prior to initiation of voluntary movement. This study examined the effects of changes in postural support on APAs using novel and familiar support paradigms. We also investigated whether postural strategies were refined with practice and how the CNS responded when multiple supports were available. Twelve healthy subjects stood on dual force platforms and performed 20 randomized left and right rapid leg-lift tasks in response to a visual cue under four conditions: unsupported, bilateral handgrip, bite plate, and a combined handgrip and bite plate condition. Vertical ground reaction forces, electromyography of limb, trunk and jaw muscles, and forces exerted on the support apparatus were recorded. Shift in center-of-pressure amplitude and duration were reduced with increased support. Muscles were recruited in advance of the focal movement when able to contribute to stability, and activity was modulated based on the amount of support available. The CNS adapted anticipatory postural strategies immediately with changes in condition regardless of familiarity with the support; however, adaptation was only complete at the first repetition in conditions that involved familiar support strategies. Tasks that involved a novel bite strategy continued to adapt with practice. In the multiple support condition, both hand and bite strategies were immediately incorporated; however, the contribution of each was not identical to conditions where supports were provided individually. This study emphasizes the flexibility of the CNS to organize postural strategies to meet the demands of postural stability in both familiar and novel situations.

Practice increases procedural errors after task interruption.

PubMed

Altmann, Erik M; Hambrick, David Z

2017-05-01

Positive effects of practice are ubiquitous in human performance, but a finding from memory research suggests that negative effects are possible also. The finding is that memory for items on a list depends on the time interval between item presentations. This finding predicts a negative effect of practice on procedural performance under conditions of task interruption. As steps of a procedure are performed more quickly, memory for past performance should become less accurate, increasing the rate of skipped or repeated steps after an interruption. We found this effect, with practice generally improving speed and accuracy, but impairing accuracy after interruptions. The results show that positive effects of practice can interact with architectural constraints on episodic memory to have negative effects on performance. In practical terms, the results suggest that practice can be a risk factor for procedural errors in task environments with a high incidence of task interruption.

'Losing my touch': decline in self-reported confidence in performing practical procedures in consultant oncologists.

PubMed

Thomson, A H; Foy, C J W; Benstead, K

2006-08-01

This study aimed to compare the confidence of oncology consultants and specialist registrars (SpRs) in the performance of practical procedures, to contrast this with confidence in other areas of practice and to determine at what grade they felt most confident. Questionnaires were sent to all 57 oncology consultants and SpRs in the South-West region. Respondents scored confidence on a five-point Likert scale. The response rate was 70%. SpRs were significantly more confident in cardiopulmonary resuscitation (p = 0.003) and central line insertion (p = 0.006). Consultants were significantly more confident in developing management plans (p = 0.001) and performing committee work (p = 0.002). Only 6% of consultants felt most confident performing practical procedures as a consultant, and were less confident about these than other tasks (p = 0.001). Some 86% of SpRs considered they were more confident performing practical procedures as senior house officers (SHOs). In conclusion, self-reported confidence in performing practical procedures declines during career progression in oncology. This raises questions about the teaching and supervision of these procedures. If there is a greater emphasis on a consultant-provided service, their educational needs will need to be recognized and retraining or outsourcing of these procedures to other specialties may be necessary.

Objectives: The objectives of this study are to describe the process of linking Association of Academic Health Sciences Libraries (AAHSL) data with 2002 LibQUAL+ data and to address four analytical questions created by the AAHSL Task Force on Quality Assessment that relate both to user satisfaction and to services provided by AAHSL libraries. Methods: For the thirty-five AAHSL libraries that participated in the 2002 LibQUAL+ survey, nested-effect of variance was analyzed using a linear mixed model. Using the Pearson correlation coefficient, this study explored four questions about the effect of user demographics on perceived levels of satisfaction with library services. Results: The supposition that library user satisfaction may differ according to library institutional reporting structure was unsupported. Regarding effect on mean overall satisfaction, size of library staff is not significant (P = 0.860), number of constituents is slightly significant (P = 0.027), and ratio of staff to constituents has a moderate and significant effect (P = 0.004). Conclusions: From a demographic perspective, the 2002 LibQUAL+ survey represents the largest cross section of AAHSL libraries. Increased understanding of how qualitative assessment can supplement quantitative data supports evidence-based decision-making and practice. It also could promote changes in data collection and usage. PMID:17252066

Enhanced radioactivity due to natural oil and gas production and related radiological problems.

PubMed

Kolb, W A; Wojcik, M

1985-10-01

Increased gamma radiation detected incidentally a few years ago in a North German oil field was traceable to radioactive scale. At the request of the Federal Ministry of the Interior a survey program was then established for dose rate measurements at various production sites, assessment of the radionuclide content of brines and scale and the Rn-222 content of natural gas. Dose equivalent rates of up to 50 mu Sv/h have been measured at the external surface of storage tanks for brines, but 73% of the 160 sites investigated did not show an increase above the natural background. Brines from gas fields contained Ra-226 of up to 286 Bq/l and scale of up to 1 kBq/g. In brines and scale from oil fields Ra-228 was usually the predominant radionuclide. Some samples contained "unsupported" Pb-210 and even Ac-227, too, but practically no uranium or thorium. The Rn-222 concentrations in natural gas samples varied between 0.004 and 4 Bq/l with a mean value of 0.6 Bq/l. It is shown that the radiation exposure due to natural gas consumption is negligible but some other problems or radiological relevance are recognized.

Chronic constipation: an evidence-based review.

PubMed

Leung, Lawrence; Riutta, Taylor; Kotecha, Jyoti; Rosser, Walter

2011-01-01

Chronic constipation is a common condition seen in family practice among the elderly and women. There is no consensus regarding its exact definition, and it may be interpreted differently by physicians and patients. Physicians prescribe various treatments, and patients often adopt different over-the-counter remedies. Chronic constipation is either caused by slow colonic transit or pelvic floor dysfunction, and treatment differs accordingly. To update our knowledge of chronic constipation and its etiology and best-evidence treatment, information was synthesized from articles published in PubMed, EMBASE, and Cochrane Database of Systematic Reviews. Levels of evidence and recommendations were made according to the Strength of Recommendation taxonomy. The standard advice of increasing dietary fibers, fluids, and exercise for relieving chronic constipation will only benefit patients with true deficiency. Biofeedback works best for constipation caused by pelvic floor dysfunction. Pharmacological agents increase bulk or water content in the bowel lumen or aim to stimulate bowel movements. Novel classes of compounds have emerged for treating chronic constipation, with promising clinical trial data. Finally, the link between senna abuse and colon cancer remains unsupported. Chronic constipation should be managed according to its etiology and guided by the best evidence-based treatment.

Articulating reproductive justice through reparative justice: case studies of abortion in Great Britain and South Africa.

PubMed

Macleod, Catriona Ida; Beynon-Jones, Siân; Toerien, Merran

2017-05-01

Public health and rights-based approaches to abortion advocacy are well established. Feminists are, however, increasingly using a broader framework of 'reproductive justice', which considers the intersecting conditions that serve to enhance or hinder women's reproductive freedoms, including their capacities to decide about the outcome of their pregnancies. Nonetheless, reproductive justice approaches to abortion are, conceptually, relatively under-developed. We introduce a reparative justice approach as a method of further articulating the concept of reproductive justice. We first explain how this approach can be used to conceptualise safe, accessible and supportive abortion as a key element of reproductive justice in relation to the injustice of unwanted or unsupportable pregnancies. Using Ernesto Verdeja's critical theory of reparative justice and case studies of two countries (South Africa and Great Britain) where abortion is legal, we show how such an approach enables an analysis of reproductive justice within the specificities of particular contexts. We argue that both the rights-based legal framework adopted in South Africa and the medicalised approach of British law have, in practice, limited reparative justice in these contexts. We discuss the implications of reparative justice for abortion advocacy.

Synthesis, characterization and assembly of metal pnictide nanoparticles, and evaluation of their physicochemical (catalytic, magnetic, and semiconducting) properties

NASA Astrophysics Data System (ADS)

Senevirathne, Keerthisinghe

Synthesis of transition metal phosphide (Ni2P) and arsenide (MnAs) discrete nanoparticles was conducted by following a solution-phase arrested precipitation route and the size- and structure-dependent physicochemical properties of these materials were explored. Furthermore, the assembly of metal phosphide nanoparticles into a network structure via a sol-gel process and the evaluation of their structure related properties also was conducted. The surface ligation chemistry of unsupported Ni2P nanoparticles prepared by arrested precipitation was found to strongly impact the structural integrity and the hydrodesulfurization (HDS) catalytic activity of Ni 2P nanoparticles. The HDS activity of unsupported surface modified Ni2P nanoparticles is higher than that of unsupported Ni2P prepared by temperature programmed reduction (TPR) but considerably lower than silica-supported Ni2P prepared by TPR. However, by supporting the pre-formed Ni 2P nanoparticles on silica, activity comparable to that of silica-supported Ni2P prepared by TPR can be achieved. The synthetic control offered by the Ni2P nanoparticle preparation, not achieved by TPR methods, is expected to enable a systematic study of particle size and shape effects on HDS activity. By using arrested precipitation reactions, for the first time, discrete and dispersible MnAs nanoparticles have been prepared and their magnetic properties evaluated. Syntheses were developed to target both the thermodynamically stable alpha-type (hexagonal) and the metastable beta-type (orthorhombic) MnAs nanoparticles. Surprisingly, both types of ˜25 nm particles exhibit nearly identical ferromagnetic behavior with blocking temperatures, T B, in the region ˜275-310 K, TC's of 315 K and room temperature coercivities of HC ˜ 190-320 Oe. No evidence of the expected structural transition from alpha to beta-MnAs at TC is observed. Oxidative sol-gel assembly of nanoparticles to make nanoparticulate gels was successfully employed to Ni2P nanoparticles, and further extended to MnP and InP nanoparticles, for the first time. The gels were transformed into highly porous, high surface area (175-270 m2/g) 3-D structures (aerogels) via CO2 supercritical drying. Relative to discrete nanoparticles, Ni2P aerogels are less active to HDS, MnP aerogels have similar magnetic properties, and InP aerogels exhibit a greater degree of quantum confinement.

This study investigated associations between coming out to parents, experiences of parental support, and self-reported health behaviors and conditions among a population-based sample of LGB individuals using data collected via the 2002 Massachusetts Behavioral Risk Factor Surveillance System (BRFSS; N = 177). We explored the following two hypotheses: 1) Lesbian, gay, and bisexual (LGB) individuals who had never disclosed their sexual orientation to a parent would report higher levels of risk behaviors and poorer health conditions than those who had come out; and 2) among LGB respondents who had come out to their parents, the individuals whose parents had reacted unsupportively would report higher levels of risk behaviors and poorer health conditions than those who had come out to parents who were supportive. Approximately two thirds of gay and bisexual (GB) males and lesbian and bisexual (LB) females reported receiving adequate social and emotional support from the parent to whom they first disclosed their sexual orientation. Among LB females, no disclosure of sexual orientation to a parent was associated with significantly elevated levels of past-month illicit drug use (AOR 12.16, 95% CI 2.87-51.54), fair or poor self-reported health status (AOR 5.71, 95% CI 1.45-22.51), and >15 days of depression in the past month (AOR 5.95, 95% CI 1.78-19.90), controlling for potential confounders. However, nondisclosure to a parent by GB males was not associated with greater odds of any of the health indicators assessed. Among GB males, those with unsupportive parents were significantly more likely to report current binge drinking (AOR 6.94, 95% CI 1.70-28.35) and >15 days depression in the past month (AOR 6.08, 95% CI 1.15-32.15), and among LB females, those with unsupportive parents were significantly more likely to report lifetime illicit drug use (AOR 11.43, 95% CI 2.50-52.30), and >15 days depression in the past month (AOR 5.51, 95% CI 1.36-22.36). We conclude that coming out may be associated with better health for LB women, and that parents who react nonsupportively when their children disclose LGB sexual orientation may contribute to children's increased odds of depression and hazardous substance use.

Women's return to work can be a significant barrier to continued breastfeeding. Workplace policies and practices to promote and support continued, and longer duration of, breastfeeding are important. In the context of the introduction of a new breastfeeding policy for Area Health Services in New South Wales, Australia, a baseline survey was conducted to describe current practices and examine women's reports of perceived organisational support on breastfeeding intention and practice. A cross sectional survey of female employees of the Sydney South West Area Health Service was conducted in late 2009. A mailed questionnaire was sent to 998 eligible participants who had taken maternity leave over the 20-month period from January 2008 to August 2009. The questionnaire collected items assessing breastfeeding intentions, awareness of workplace policies, and the level of organisational and social support available. For those women who had returned to work, further questions were asked to assess the perceptions and practices of breastfeeding in the work environment, as well as barriers and enabling factors to combining breastfeeding and work. Returning to work was one of the main reasons women ceased breastfeeding, with 60 percent of women intending to breastfeed when they returned to work, but only 40 percent doing so. Support to combine breastfeeding and work came mainly from family and partners (74% and 83% respectively), with little perceived support from the organisation (13%) and human resources (6%). Most women (92%) had received no information from their managers about their breastfeeding options upon their return to work, and few had access to a room specially designated for breastfeeding (19%). Flexible work options and lactation breaks, as well as access to a private room, were identified as the main factors that facilitate breastfeeding at work. Enabling women to continue breastfeeding at work has benefits for the infant, employee and organisation. However, this baseline study of health employees revealed that women felt largely unsupported by managers and their organisation to continue breastfeeding at work.

Interventional procedures directed toward sources of pain in the axial and appendicular musculoskeletal system are performed with increasing frequency. Despite the presence of evidence-based guidelines for such procedures, there are wide variations in practice. Case reports of serious complications such as spinal cord infarction or infection from spine injections lack appropriate context and create a misleading view of the risks of appropriately performed interventional pain procedures. To evaluate adverse event rate for interventional spine procedures performed at three academic interventional spine practices. Quality assurance databases at three academic interventional pain management practices that utilize evidence-based guidelines [1] were interrogated for immediate complications from interventional pain procedures. Review of the electronic medical record verified or refuted the occurrence of a complication. Same-day emergency department transfers or visits were also identified by a records search. Immediate complication data were available for 26,061 consecutive procedures. A radiology practice performed 19,170 epidural steroid (primarily transforaminal), facet, sacroiliac, and trigger point injections (2006-2013). A physiatry practice performed 6,190 spine interventions (2004-2009). A second physiatry practice performed 701 spine procedures (2009-2010). There were no major complications (permanent neurologic deficit or clinically significant bleeding [e.g., epidural hematoma]) with any procedure. Overall complication rate was 1.9% (493/26,061). Vasovagal reactions were the most frequent event (1.1%). Nineteen patients (<0.1%) were transferred to emergency departments for: allergic reactions, chest pain, symptomatic hypertension, and a vasovagal reaction. This study demonstrates that interventional pain procedures are safely performed with extremely low immediate adverse event rates when evidence-based guidelines are observed. © 2016 American Academy of Pain Medicine.

2015-03-01

Our main research objective was to determine the biological bases for low-dose, radiation-induced adaptive responses in the lung, and use the knowledge gained to produce an improved risk model for radiation-induced lung cancer that accounts for activated natural protection, genetic influences, and the role of epigenetic regulation (epiregulation). Currently, low-dose radiation risk assessment is based on the linear-no-threshold hypothesis, which now is known to be unsupported by a large volume of data.

Palmer, Michael C.; Deroba, Jonathan J.; Legault, Christopher M.; Brooks, Elizabeth N.

2016-04-01

Pershing et al. (Reports, 13 November, p. 809) concluded that failure to account for temperature in the assessment and management of Gulf of Maine Atlantic cod caused overfishing. We argue that the “extra mortality” calculation driving this conclusion is an artifact. Environmental factors affect all stocks, but attribution of additional mortality to temperature alone by Pershing et al. is unsupported by the data.

Response to formal comment on Myhrvold (2016) submitted by Griebeler and Werner (2017)

PubMed Central

2018-01-01

Griebeler and Werner offer a formal comment on Myhrvold, 2016 defending the conclusions of Werner and Griebeler, 2014. Although the comment criticizes several aspects of methodology in Myhrvold, 2016, all three papers concur on a key conclusion: the metabolism of extant endotherms and ectotherms cannot be reliably classified using growth-rate allometry, because the growth rates of extant endotherms and ectotherms overlap. A key point of disagreement is that the 2014 paper concluded that despite this general case, one can nevertheless classify dinosaurs as ectotherms from their growth rate allometry. The 2014 conclusion is based on two factors: the assertion (made without any supporting arguments) that the comparison with dinosaurs must be restricted only to extant sauropsids, ignoring other vertebrate groups, and that extant sauropsid endotherm and ectotherm growth rates in a data set studied in the 2014 work do not overlap. The Griebeler and Werner formal comment presents their first arguments in support of the restriction proposition. In this response I show that this restriction is unsupported by established principles of phylogenetic comparison. In addition, I show that the data set studied in their 2014 work does show overlap, and that this is visible in one of its figures. I explain how either point effectively invalidates the conclusion of their 2014 paper. I also address the other methodological criticisms of Myhrvold 2016, and find them unsupported. PMID:29489880

Theory of linear sweep voltammetry with diffuse charge: Unsupported electrolytes, thin films, and leaky membranes

Linear sweep and cyclic voltammetry techniques are important tools for electrochemists and have a variety of applications in engineering. Voltammetry has classically been treated with the Randles-Sevcik equation, which assumes an electroneutral supported electrolyte. In this paper, we provide a comprehensive mathematical theory of voltammetry in electrochemical cells with unsupported electrolytes and for other situations where diffuse charge effects play a role, and present analytical and simulated solutions of the time-dependent Poisson-Nernst-Planck equations with generalized Frumkin-Butler-Volmer boundary conditions for a 1:1 electrolyte and a simple reaction. Using these solutions, we construct theoretical and simulated current-voltage curves for liquid and solid thin films, membranes with fixed background charge, and cells with blocking electrodes. The full range of dimensionless parameters is considered, including the dimensionless Debye screening length (scaled to the electrode separation), Damkohler number (ratio of characteristic diffusion and reaction times), and dimensionless sweep rate (scaled to the thermal voltage per diffusion time). The analysis focuses on the coupling of Faradaic reactions and diffuse charge dynamics, although capacitive charging of the electrical double layers is also studied, for early time transients at reactive electrodes and for nonreactive blocking electrodes. Our work highlights cases where diffuse charge effects are important in the context of voltammetry, and illustrates which regimes can be approximated using simple analytical expressions and which require more careful consideration.

Comparative Proteomic Analysis of Supportive and Unsupportive Extracellular Matrix Substrates for Human Embryonic Stem Cell Maintenance*

Human embryonic stem cells (hESCs) are pluripotent cells that have indefinite replicative potential and the ability to differentiate into derivatives of all three germ layers. hESCs are conventionally grown on mitotically inactivated mouse embryonic fibroblasts (MEFs) or feeder cells of human origin. In addition, feeder-free culture systems can be used to support hESCs, in which the adhesive substrate plays a key role in the regulation of stem cell self-renewal or differentiation. Extracellular matrix (ECM) components define the microenvironment of the niche for many types of stem cells, but their role in the maintenance of hESCs remains poorly understood. We used a proteomic approach to characterize in detail the composition and interaction networks of ECMs that support the growth of self-renewing hESCs. Whereas many ECM components were produced by supportive and unsupportive MEF and human placental stromal fibroblast feeder cells, some proteins were only expressed in supportive ECM, suggestive of a role in the maintenance of pluripotency. We show that identified candidate molecules can support attachment and self-renewal of hESCs alone (fibrillin-1) or in combination with fibronectin (perlecan, fibulin-2), in the absence of feeder cells. Together, these data highlight the importance of specific ECM interactions in the regulation of hESC phenotype and provide a resource for future studies of hESC self-renewal. PMID:23658023

2017-07-01

The development of navigation technology facilitating MRI-guided stereotactic neurosurgery has enabled neurosurgeons to perform a variety of procedures ranging from deep brain stimulation to laser ablation entirely within an intraoperative or diagnostic MRI suite while having real-time visualization of brain anatomy. Prior to this technology, some of these procedures required multisite workflow patterns that presented significant risk to the patient during transport. For those facilities with access to this technology, safe practice guidelines exist only for procedures performed within an intraoperative MRI. There are currently no safe practice guidelines or parameters available for facilities looking to integrate this technology into practice in conventional MRI suites. Performing neurosurgical procedures in a diagnostic MRI suite does require precautionary measures. The relative novelty of technology and workflows for direct MRI-guided procedures requires consideration of safe practice recommendations, including those pertaining to infection control and magnet safety issues. This article proposes a framework of safe practice recommendations designed for assessing readiness and optimization of MRI-guided neurosurgical interventions in the diagnostic MRI suite in an effort to mitigate patient risk. The framework is based on existing clinical evidence, recommendations, and guidelines related to infection control and prevention, health care-associated infections, and magnet safety, as well as the clinical and practical experience of neurosurgeons utilizing this technology. © 2017 American Society for Healthcare Risk Management of the American Hospital Association.

The medical practice of euthanasia in Belgium and The Netherlands: legal notification, control and evaluation procedures.

2009-05-01

To describe and compare current legal procedures for notifying, controlling and evaluating (NCE-procedures) euthanasia in Belgium and the Netherlands, and to discuss the implications for a safe and controllable euthanasia practice. We systematically studied and compared official documents relating to the Belgian and the Dutch NCE-procedures for euthanasia. In both countries, physicians are required to notify their cases to a review Committee, stimulating them to safeguard the quality of their euthanasia practice and to make societal control over the practice of euthanasia possible. However, the procedures in both countries differ. The main differences are that the Dutch notification and control procedures are more elaborate and transparent than the Belgian, and that the Belgian procedures are primarily anonymous, whereas the Dutch are not. Societal evaluation is made in both countries through the Committees' summary reports to Parliament. Transparent procedures like the Dutch may better facilitate societal control. Informing physicians about the law and the due care requirements for euthanasia, and systematic feedback about their medical actions are both pivotal to achieving efficient societal control and engendering the level of care needed when performing such far-reaching medical acts.

Work Loads and Practice Patterns of General Surgeons in the United States, 1995–1997

Ritchie, Wallace P.; Rhodes, Robert S.; Biester, Thomas W.

1999-01-01

Objective To characterize the work loads and practice patterns of general surgeons in the United States over a 3-year period (1995 to 1997). Methods The surgical operative logs of 2434 “generalist” general surgeons recertifying in surgery form the basis of this report. Selected demographics of the group are as follows: location: 50% Northeast and Southeast, 21% Midwest, 29% West and Southwest; practice type: 45% solo, 40% group, 9% academics; size of practice community: 46% highly urban, 19% rural. Parameters evaluated were the average number of procedures and their distribution by category related to geographic area, practice type, community size, and other parameters. Statistical analysis was accomplished using analysis of variance. Results No significant year-to-year differences were observed between cohorts. The average numbers of procedures per surgeon per year was 398, distributed as follows: abdomen 102, alimentary tract 63, breast 54, endoscopic 51, vascular 39, trauma 6, endocrine 4, and head and neck, 3. Eleven percent of the 398 procedures were performed laparoscopically. Major index cases were largely concentrated with small groups of surgeons representing 5% to 10% of the total. Significant differences were as follows: surgeons in the Northeast and West performed far fewer procedures than those elsewhere. Urban surgeons performed a few more tertiary-type procedures than did rural ones; however, rural surgeons performed many more total procedures, especially in endoscopy, laparoscopy, gynecology, genitourinary, and orthopedics. Academic surgeons performed substantially fewer total procedures as a group than did nonacademic ones and in all categories except liver, transplant, and pancreas. Male surgeons performed more procedures than did female surgeons, except those involving the breast. More procedures were done by surgeons in group practice than by those in solo practice. U.S. medical graduates and international medical graduates had similar work loads but with a different distribution. Conclusions This unique database will be useful in tracking trends over time. More importantly, it demonstrates that general surgery practice in the United States is extremely heterogeneous, a fact that must be acknowledged in any future workforce deliberations. PMID:10522723

We explore dyadic parenting styles and their association with first-grade children’s externalizing behavior symptoms in a sample of 85 working-class, dual-earner families. Cluster analysis is used to create a typology of parenting types, reflecting the parental warmth, overreactivity, and laxness of both mothers and fathers in two-parent families. Three distinct groups emerged: Supportive Parents, Mixed-Support Parents and Unsupportive Parents. Results indicate that dyadic parenting styles were related to teacher-reported externalizing symptoms for boys but not for girls. PMID:20221305

Getting better together? Opportunities and limitations for technology-facilitated social support in cardiac rehabilitation.

Maitland, Julie

2011-01-01

Social support has long been positively correlated with cardiac outcomes. However, sources of tension surrounding peer-involvement in the period following acute cardiac events are well documented. Informed by a previous study of patient perspectives of peer-involvement in cardiac rehabilitation, this paper draws from the cardiac and computing literature to provide actionable insights into how technology could be designed to promote appropriate peer-involvement and the challenges that may be faced when designing technologies to support the unsupported.

Measuring attitude with a gradiometer

NASA Technical Reports Server (NTRS)

Sonnabend, David; Born, George H.

1994-01-01

Static attitude estimation and dynamic attitude estimation are used to describe a gradiometer composed of a number of accelerometers that are used to measure a combination of the local gravity gradient and instrument rotation effects. After a series of measures to isolate the gradient, a global mesh of measurements can be obtained that determine the planetary external gravity potential. Orbital and spacecraft models are developed to determine if, when the gravity potential is known, the same measurements, unsupported by any other information can be used to infer the spacecraft attitude.

2014-06-01

The literature fails to reflect general agreement over the nature of the services and procedures provided by bioethicists, and the training and core competencies this work requires. If bioethicists are to define their activities in a consistent way, it makes sense to look for common ground in shared communities of practice. We report results of a survey of the services and procedures among bioethicists affiliated with the University of Toronto Joint Centre for Bioethics (JCB). This is the largest group of bioethicists working in healthcare organizations in Canada. The results suggest there are many common services and procedures of JCB bioethicists. This survey can serve as a baseline for further exploration of the work of JCB bioethicists. Common practices exist with respect to the domains of practice, individual reporting relationships, service availability within business hours and the education and training of the bioethicist.

Security breaches: tips for assessing and limiting your risks.

PubMed

Coons, Leeanne R

2011-01-01

As part of their compliance planning, medical practices should undergo a risk assessment to determine any vulnerability within the practice relative to security breaches. Practices should also implement safeguards to limit their risks. Such safeguards include facility access controls, information and electronic media management, use of business associate agreements, and education and enforcement. Implementation of specific policies and procedures to address security incidents is another critical step that medical practices should take as part of their security incident prevention plan. Medical practices should not only develop policies and procedures to prevent, detect, contain, and correct security violations, but should make sure that such policies and procedures are actually implemented in their everyday operations.

Breslin, E H; Adams, E; Lutz, A; Roy, C

1993-06-01

Many daily activities, from basic grooming to employment tasks, require adequate unsupported arm endurance (UAE). We developed an electromechanical device to measure UAE endurance. The purpose of this study was to standardize the instrument for two rates of arm motion, moderate and slow, in 18 normal adult subjects (FEVI = 3.7L +/- .78, FVC = 4.2L +/- .74, FEV1/FVC = 1.1 +/- .08). Exercise endurance limits, and the following metabolic, ventilatory, and sensation responses were determined at rest prior to exercise and at end-exercise limits for both rates of UAE:minute ventilation (Ve), tidal volume (VT), respiratory rate (RR), duty cycle (Ti/Ttot), oxygen uptake (VO2), carbon dioxide production (VCO2), inspiratory flow (VT/Ti), heart rate (HR), and visual analog scale measurements (VAS) of dyspnea (D), respiratory effort (RE), and arm fatigue (AF). Significance increases from baseline rest were shown at the endurance limits for both rates of UAE in: VO2, VCO2, Ve, VT, RR, VT/Ti, HR, VAS-D, VAS-RE, and VAS-AF. There were no changes in Ti/Ttot and SaO2 with UAE. Peak VO2, RR, Ve, VT/Ti, and VAS-D with moderate exercise were significantly greater than slow UAE; and there was a trend increase in peak HR for moderate as opposed to slow rate UAE. Despite these differences, the endurance time between the two rates of UAE were similar. These data provide standards against which UAE in COPD can be evaluated.

Technology for advanced liquefaction processes: Coal/waste coprocessing studies

1995-12-31

The efforts in this project are directed toward three areas: (1) novel catalyst (supported and unsupported) research and development, (2) study and optimization of major operating parameters (specifically pressure), and (3) coal/waste coprocessing. The novel catalyst research and development activity has involved testing supported catalysts, dispersed catalysts, and use of catalyst testing units to investigate the effects of operating parameters (the second area) with both supported and unsupported catalysts. Several supported catalysts were tested in a simulated first stage coal liquefaction application at 404{degrees}C during this performance period. A Ni-Mo hydrous titanate catalyst on an Amocat support prepared by Sandiamore » National laboratories was tested. Other baseline experiments using AO-60 and Amocat, both Ni-Mo/Al{sub 2}O{sub 3} supported catalysts, were also made. These experiments were short duration (approximately 12 days) and monitored the initial activity of the catalysts. The results of these tests indicate that the Sandia catalyst performed as well as the commercially prepared catalysts. Future tests are planned with other Sandia preparations. The dispersed catalysts tested include sulfated iron oxide, Bayferrox iron oxide (iron oxide from Miles, Inc.), and Bailey iron oxide (micronized iron oxide from Bailey, Inc.). The effects of space velocity, temperature, and solvent-to-coal ratio on coal liquefaction activity with the dispersed catalysts were investigated. A comparison of the coal liquefaction activity of these catalysts relative to iron catalysts tested earlier, including FeOOH-impregnated coal, was made. These studies are discussed.« less

Generation-specific incentives and disincentives for nurse faculty to remain employed.

PubMed

Tourangeau, Ann E; Wong, Matthew; Saari, Margaret; Patterson, Erin

2015-05-01

The aims of this paper are to: (1) describe work characteristics that nurse faculty report encourage them to remain in or leave their academic positions; and (2) determine if there are generational differences in work characteristics selected. Nurse faculty play key roles in preparing new nurses and graduate nurses. However, educational institutions are challenged to maintain full employment in faculty positions. A cross-sectional, descriptive survey design was employed. Ontario nurse faculty were asked to select, from a list, work characteristics that entice them to remain in or leave their faculty positions. Respondent data (n = 650) were collected using mailed surveys over four months in 2011. While preferred work characteristics differed across generations, the most frequently selected incentives enticing nurse faculty to stay were having: a supportive director/dean, reasonable workloads, supportive colleagues, adequate resources, manageable class sizes and work/life balance. The most frequently selected disincentives included: unmanageable workloads, unsupportive organizations, poor work environments, exposure to bullying, belittling and other types of incivility in the workplace and having an unsupportive director/dean. This research yields new and important knowledge about work characteristics that nurse faculty report shape their decisions to remain in or leave their current employment. Certain work characteristics were rated as important among all generations. Where similarities exist, broad strategies addressing work characteristics may effectively promote nurse faculty retention. However, where generational differences exist, retention-promoting strategies should target generation-specific preferences. © 2014 John Wiley & Sons Ltd.

To examine doctors' experiences of complaints, including which aspects are most stressful. We also investigated how doctors felt complaints processes could be improved. A qualitative study based on a cross-sectional survey of members of the British Medical Association (BMA). We asked the following: (1) Try to summarise as best as you can your experience of the complaints process and how it made you feel. (2) What were the most stressful aspects of the complaint? (3) What would you improve in the complaints system? We sent the survey to 95 636 doctors, and received 10 930 (11.4%) responses. Of these, 6146 had a previous, recent or current complaint and 3417 (31.3%) of these respondents answered questions 1 and 2. We randomly selected 1000 answers for analysis, and included 100 using the saturation principle. Of this cohort, 93 responses for question 3 were available. Doctors frequently reported feeling powerless, emotionally distressed, and experiencing negative feelings towards both those managing complaints and the complainants themselves. Many felt unsupported, fearful of the consequences and that the complaint was unfair. The most stressful aspects were the prolonged duration and unpredictability of procedures, managerial incompetence, poor communication and perceiving that processes are biased in favour of complainants. Many reported practising defensively or considering changing career after a complaint, and few found any positive outcomes from complaints investigations. Physicians suggested procedures should be more transparent, competently managed, time limited, and that there should be an open dialogue with complainants and policies for dealing with vexatious complaints. Some felt more support for doctors was needed. Complaints seriously impact on doctors' psychological wellbeing, and are associated with defensive practise. This is not beneficial to patient care. To improve procedures, doctors propose they are simplified, time limited and more transparent. Published by the BMJ Publishing Group Limited.

Peri-procedural protocols for interventional pain management techniques: a survey of US pain centers.

PubMed

Ahmed, Shihab U; Tonidandel, William; Trella, Jason; Martin, Nicole M; Chang, Yuchiao

2005-04-01

Interventional techniques are now an integral part of chronic pain management. As new procedures are arising at a rapid pace, decisions regarding patient safety and comfort are becoming more challenging. No peri-procedural consensus protocol currently addresses issues such as 1. nulla per os (NPO) status, 2. sedation, 3. monitoring, or 4. recovery. In establishing safety guidelines for interventional pain procedures, the knowledge of current peri-procedural protocols is required. To survey interventional pain practices and to obtain current peri-procedural protocols. We faxed a one-page questionnaire to 105 United States pain practices identified using the directory of the American Pain Society. Fifty-seven academic and private pain practices (54%) responded and were included in the analysis. Monitoring devices such as electrocardiogram (EKG), blood pressure, and pulse oximetry are not universally employed for cervical or lumbar spinal procedures. Even procedures that are often performed by anesthesiologists in operating rooms, such as Bier blocks, are not monitored in a uniform manner when performed in pain clinics. Establishment of intravenous access for procedures also varies among practitioners. Most (72%) practices had treated patients with vasovagal reactions over the past 12 months, but only 42% had simulated cardiac arrests to prepare for these situations. While various trends in peri-procedural care are observable, standards of care are not well established. In order to minimize complications associated with interventional pain management techniques, the pain management community should agree on safety guidelines for all procedures, much as these advocated by the American Society of Anesthesiology for surgical anesthetic care.

Mutilating Procedures, Management Practices, and Housing Conditions That May Affect the Welfare of Farm Animals: Implications for Welfare Research

PubMed Central

Nordquist, Rebecca E.; van der Staay, Franz Josef; van Eerdenburg, Frank J. C. M.; Velkers, Francisca C.; Fijn, Lisa; Arndt, Saskia S.

2017-01-01

Simple summary Intensive farming systems are confronted with a number of animal welfare issues such as injuries from horns in cattle and feather pecking in poultry. To solve these problems, mutilating procedures, such as dehorning in cattle and goats and beak trimming in laying hens, are applied routinely. These and other procedures such as early maternal separation, overcrowding, and barren housing conditions impair animal welfare. Scientific underpinning of the efficacy of these interventions and management practices is poor. We advocate that all stakeholders, in particular animal scientists and veterinarians, take the lead in evaluating common, putative mutilating and welfare reducing procedures and management practices to develop better, scientifically supported alternatives, focused on adaptation of the environment to the animals, to ensure uncompromised animal welfare. Abstract A number of mutilating procedures, such as dehorning in cattle and goats and beak trimming in laying hens, are common in farm animal husbandry systems in an attempt to prevent or solve problems, such as injuries from horns or feather pecking. These procedures and other practices, such as early maternal separation, overcrowding, and barren housing conditions, raise concerns about animal welfare. Efforts to ensure or improve animal welfare involve adapting the animal to its environment, i.e., by selective breeding (e.g., by selecting “robust” animals) adapting the environment to the animal (e.g., by developing social housing systems in which aggressive encounters are reduced to a minimum), or both. We propose adapting the environment to the animals by improving management practices and housing conditions, and by abandoning mutilating procedures. This approach requires the active involvement of all stakeholders: veterinarians and animal scientists, the industrial farming sector, the food processing and supply chain, and consumers of animal-derived products. Although scientific evidence about the welfare effects of current practices in farming such as mutilating procedures, management practices, and housing conditions is steadily growing, the gain in knowledge needs a boost through more scientific research. Considering the huge number of animals whose welfare is affected, all possible effort must be made to improve their welfare as quickly as possible in order to ban welfare-compromising procedures and practices as soon as possible.

Creativity and Innovation in Health Care: Tapping Into Organizational Enablers Through Human-Centered Design.

PubMed

Zuber, Christi Dining; Moody, Louise

There is an increasing drive in health care for creativity and innovation to tackle key health challenges, improve quality and access, and reduce harm and costs. Human-centered design (HCD) is a potential approach to achieving organizational innovation. However, research suggests the nursing workforce feels unsupported to take the risks needed for innovation, and leaders may not understand the conditions required to fully support them. The aim of this study was to identify enabling conditions that support frontline nurses in their attempts to behave as champions of innovation and change. An HCD workshop was undertaken with 125 nurses employed in clinical practice at Kaiser Permanente. The workshop included empathy mapping and semistructured questions that probed participant experiences with innovation and change. The data were collated and thematic analysis undertaken through a Grounded Theory approach. The data were analyzed to identify key enabling conditions. Seven enablers emerged: personal need for a solution; challenges that have meaningful purpose; clarity of goal and control of resources; active experimentation; experiences indicating progress; positive encouragement and confidence; and provision of psychological safety. These enablers were then translated into pragmatic guidelines for leaders on how the tools of HCD may be leveraged for innovation and change in health care.

Stress is one of the most common problems; one manifestation of stress is burnout. Burnout and other stress-related illnesses among medical professionals are receiving increased attention and have been described in many branches of medical practice including dentists, nurses, etc., The purpose of this study was to measure the prevalence of stress and burnout in medical professionals in Rajasthan. The Maslach Burnout Inventory-Human Service Survey (MBI-HSS) and a demographic questionnaire of our own design were sent to 1,735 medical professional of various branches and different location throughout the state of Rajasthan. In response to that, 627 (36%) surveys were returned, of which 576 (92%) were found complete for analysis so later group constitute as sample for analysis. 29.16% of medical professional showed high level of emotional exhaustion (EE), 20% showed high level of depersonalization (DP), and 17.9% showed low personal accomplishment (PA). Young professionals showed more sensitivity towards burnout (r = -0.122, P < 0.003). Females were more prone to burnout (40%) as compared to males (27%). Burnout is an important problem in medical professionals in Rajasthan. Difference in approach to work and perceived environment at workplace, unrewarding career, unsupported behavior of peer group, balance between work and family needs appear to be important factors in burnout.

This article analyzes how the behaviors of leaders and peers affect the performance and well-being of military women. Locating our analysis within the conceptual model in this issue, we summarize the empirical literature and make practice and policy recommendations. We synthesize results about unit integration, such as research on the conditions for successful integration of previously excluded groups and on the relationship between cohesion and performance. We apply lessons learned from the history of diversity integration in military and civilian organizations, analyzing the treatment of military personnel by race, gender, and sexual orientation. The opening of ground combat specialties and units to women is the latest step in personnel policy changes broadening the recruitment base. We analyze research on gender integration in contemporary armed forces, focusing on positive and negative effects on women of leader and peer behaviors. We discuss conditions for successfully integrating women and those that tend to lead to failure. We analyze military women's family issues, including the effects of deployments and how leaders and peers can help ameliorate problems-or exacerbate them with inappropriate or unsupportive behavior.

Forrest, G C; Standish, E; Baum, J D

1982-01-01

After an earlier study into the practical aspects of the management of perinatal death, a counselling service was introduced for parents whose baby had died in the perinatal period. The service was monitored, and the parents who received the service were compared with a group that did not. Fifty families were allocated randomly either to the counselling (supported) group or to the contrast group, who received routine hospital care. Assessment was carried out at six and 14 months after the death, using a semi-structured interview and two self-rating scales (the general health questionnaire and the Leeds scales). Two of 16 mothers in the supported group showed psychiatric disorder at six months, compared with 10 of 19 in the contrast group (p less than 0.01, Fisher's exact test). There was no significant difference between the two groups at 14 months, when 80% of all the women studied had recovered psychiatric symptoms. Socially isolated women and those who marital relations lacked intimacy had a higher incidence of psychiatric symptoms at six months. Early pregnancy (within six months) was associated with a higher incidence of psychiatric symptoms in the unsupported group. The duration of bereavement reaction after perinatal death was appreciably shortened by support and counselling. PMID:6814610

A Sinter-Resistant Catalytic System Based on Platinum Nanoparticles Supported on TiO2 Nanofibers and Covered by Porous Silica

Platinum is a key catalyst that is invaluable in many important industrial processes such as CO oxidation in catalytic converters, oxidation and reduction reactions in fuel cells, nitric acid production, and petroleum cracking.[1] Many of these applications utilize Pt nanoparticles supported on oxides or porous carbon.[2] However, in practical applications that involve high temperatures (typically higher than 3008C), the Pt nanoparticles tend to lose their specific surface area and thus catalytic activity during operation because of sintering. Recent studies have shown that a porous oxide shell can act as a physical barrier to prevent sintering of unsupported metal nanoparticles and,more » at the same time, provide channels for chemical species to reach the surface of the nanoparticles, thus allowing the catalytic reaction to occur. This concept has been demonstrated in several systems, including Pt@SiO2,[3] Pt@CoO,[4] Pt/CeO2@SiO2,[5] Pd@SiO2,[6] Au@SiO2,[7] Au@SnO2 [8] and Au@ZrO2 [9] core– shell nanostructures. Despite these results, a sinter-resistant system has not been realized in supported Pt nanoparticle catalysts.« less

Evaluating Alcoholics Anonymous's effect on drinking in Project MATCH using cross-lagged regression panel analysis.

PubMed

Magura, Stephen; Cleland, Charles M; Tonigan, J Scott

2013-05-01

The objective of the study is to determine whether Alcoholics Anonymous (AA) participation leads to reduced drinking and problems related to drinking within Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity), an existing national alcoholism treatment data set. The method used is structural equation modeling of panel data with cross-lagged partial regression coefficients. The main advantage of this technique for the analysis of AA outcomes is that potential reciprocal causation between AA participation and drinking behavior can be explicitly modeled through the specification of finite causal lags. For the outpatient subsample (n = 952), the results strongly support the hypothesis that AA attendance leads to increases in alcohol abstinence and reduces drinking/ problems, whereas a causal effect in the reverse direction is unsupported. For the aftercare subsample (n = 774), the results are not as clear but also suggest that AA attendance leads to better outcomes. Although randomized controlled trials are the surest means of establishing causal relations between interventions and outcomes, such trials are rare in AA research for practical reasons. The current study successfully exploited the multiple data waves in Project MATCH to examine evidence of causality between AA participation and drinking outcomes. The study obtained unique statistical results supporting the effectiveness of AA primarily in the context of primary outpatient treatment for alcoholism.

Dentists have much invested in their practices. They need to protect their practices from fraud and noncompliance. The author provides practical suggestions for how to significantly reduce the risk of fraud and theft in the practice without disrupting day-to-day operations. By adhering to nonintrusive policy and procedure changes, dental practice owners can reduce inherent risks of fraud and theft, while increasing financial and human resource knowledge regarding their practice. Practice owners with the appropriate policies and procedures benefit from significantly lower risk of loss from fraud and theft. Furthermore, they have a better understanding of their practice's finances and human resources. Copyright © 2015 American Dental Association. Published by Elsevier Inc. All rights reserved.

(Non) formation of methanol by direct hydrogenation of formate on copper catalysts

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

Yang, Yong; Mims, Charles A.; Disselkamp, Robert S.

2010-10-14

We have attempted to hydrogenate adsorbed formate species on copper catalysts to probe the importance of this postulated mechanistic step in methanol synthesis. Surface formate coverages up to 0.25 were produced at temperatures between 413K and 453K on supported (Cu/SiO2) copper and unsupported copper catalysts. The adlayers were produced by various methods including (1) steady state catalytic conditions in CO2-H2 (3:1, 6 bar) atmospheres, and (2) by exposure of the catalysts to formic acid. As reported in earlier work, the catalytic surface at steady state contains bidentate formate species with coverages up to saturation levels of ~ 0.25 at themore » low temperatures of this study. The reactivity of these formate adlayers was investigated at relevant reaction temperatures in atmospheres containing up to 6 bar H2 partial pressure by simultaneous mass spectrometry (MS) and infrared (IR) spectroscopy measurements. The yield of methanol during the attempted hydrogenation (“titration”) of these adlayers was insignificant (<0.2 mol % of the formate adlayer) even in dry hydrogen partial pressures up to 6 bar. Hydrogen titration of formate species produced from formic acid also failed to produce significant quantities of methanol, and attempted titration in gases consisting of CO-hydrogen mixtures or dry CO2 were also unproductive. The formate decomposition kinetics, measured by IR, were also unaffected by these changes in the gas composition. Similar experiments on unsupported copper also failed to show any methanol. From these results, we conclude that methanol synthesis on copper cannot result from the direct hydrogenation of (bidentate) formate species in simple steps involving adsorbed H species alone. Furthermore, experiments performed on both supported (Cu/SiO2) and unsupported copper catalysts gave similar results implying that the methanol synthesis reaction mechanism only involves metal surface chemistry. Pre-exposure of the bidentate formate adlayer to oxidation by O2 or N2O produces a change to a monodentate configuration. Attempted titration of this monodentate formate/O coadsorbed layer in dry hydrogen produces significant quantities of methanol, although decomposition of formate to carbon dioxide and hydrogen remains the dominant reaction pathway. Simultaneous production of water is also observed during this titration as the copper surface is re-reduced. These results indicate that co-adsorbates related to surface oxygen or water-derived species may be critical to methanol production on copper, perhaps assisting in the hydrogenation of adsorbed formate to adsorbed methoxyl.« less

Mutilating Procedures, Management Practices, and Housing Conditions That May Affect the Welfare of Farm Animals: Implications for Welfare Research.

PubMed

2017-02-21

A number of mutilating procedures, such as dehorning in cattle and goats and beak trimming in laying hens, are common in farm animal husbandry systems in an attempt to prevent or solve problems, such as injuries from horns or feather pecking. These procedures and other practices, such as early maternal separation, overcrowding, and barren housing conditions, raise concerns about animal welfare. Efforts to ensure or improve animal welfare involve adapting the animal to its environment, i.e., by selective breeding (e.g., by selecting "robust" animals) adapting the environment to the animal (e.g., by developing social housing systems in which aggressive encounters are reduced to a minimum), or both. We propose adapting the environment to the animals by improving management practices and housing conditions, and by abandoning mutilating procedures. This approach requires the active involvement of all stakeholders: veterinarians and animal scientists, the industrial farming sector, the food processing and supply chain, and consumers of animal-derived products. Although scientific evidence about the welfare effects of current practices in farming such as mutilating procedures, management practices, and housing conditions is steadily growing, the gain in knowledge needs a boost through more scientific research. Considering the huge number of animals whose welfare is affected, all possible effort must be made to improve their welfare as quickly as possible in order to ban welfare-compromising procedures and practices as soon as possible.

General surgery graduates may be ill prepared to enter rural or community surgical practice.

Rural/community surgery presents unique challenges to general surgeons. Not only are they required to perform "classic" general surgery procedures, but they are also often expected to be competent in other surgical disciplines. Final-year Canadian-trained residents in general surgery were asked to complete the survey. The survey explored chief residents' career plans for the following year and whether or not they would independently perform various procedures, some general surgical, and others now considered within the domain of the subspecialties. Sixty-four residents (71%) completed the survey. Twenty percent planned to undertake a rural surgical practice, 17% an urban community practice, and 55% had confirmed fellowships. Most residents (>90%) expressed comfort with basic general surgical procedures. However, residents were less comfortable with subspecialty procedures that are still performed by general surgeons in many rural practices. More than half of graduating general surgery residents are choosing subspecialty fellowship training over proceeding directly to practice. Those choosing a rural or community practice are likely to feel ill prepared to replace existing surgeons. Copyright © 2013 Elsevier Inc. All rights reserved.

Simulation center training as a means to improve resident performance in percutaneous noncontinuous CT-guided fluoroscopic procedures with dose reduction.

PubMed

Mendiratta-Lala, Mishal; Williams, Todd R; Mendiratta, Vivek; Ahmed, Hafeez; Bonnett, John W

2015-04-01

The purpose of this study was to evaluate the effectiveness of a multifaceted simulation-based resident training for CT-guided fluoroscopic procedures by measuring procedural and technical skills, radiation dose, and procedure times before and after simulation training. A prospective analysis included 40 radiology residents and eight staff radiologists. Residents took an online pretest to assess baseline procedural knowledge. Second-through fourth-year residents' baseline technical skills with a procedural phantom were evaluated. First-through third-year residents then underwent formal didactic and simulation-based procedural and technical training with one of two interventional radiologists and followed the training with 1 month of supervised phantom-based practice. Thereafter, residents underwent final written and practical examinations. The practical examination included essential items from a 20-point checklist, including site and side marking, consent, time-out, and sterile technique along with a technical skills portion assessing pedal steps, radiation dose, needle redirects, and procedure time. The results indicated statistically significant improvement in procedural and technical skills after simulation training. For residents, the median number of pedal steps decreased by three (p=0.001), median dose decreased by 15.4 mGy (p<0.001), median procedure time decreased by 4.0 minutes (p<0.001), median number of needle redirects decreased by 1.0 (p=0.005), and median number of 20-point checklist items successfully completed increased by three (p<0.001). The results suggest that procedural skills can be acquired and improved by simulation-based training of residents, regardless of experience. CT simulation training decreases procedural time, decreases radiation dose, and improves resident efficiency and confidence, which may transfer to clinical practice with improved patient care and safety.

This study examined the impact of expanded function allied dental personnel on the productivity and efficiency of general dental practices. Detailed practice financial and clinical data were obtained from a convenience sample of 154 general dental practices in Colorado. In this state, expanded function dental assistants can provide a wide range of reversible dental services/procedures, and dental hygienists can give local anesthesia. The survey identified practices that currently use expanded function allied dental personnel and the specific services/procedures delegated. Practice productivity was measured using patient visits, gross billings, and net income. Practice efficiency was assessed using a multivariate linear program, Data Envelopment Analysis. Sixty-four percent of the practices were found to use expanded function allied dental personnel, and on average they delegated 31.4 percent of delegatable services/procedures. Practices that used expanded function allied dental personnel treated more patients and had higher gross billings and net incomes than those practices that did not; the more services they delegated, the higher was the practice's productivity and efficiency. The effective use of expanded function allied dental personnel has the potential to substantially expand the capacity of general dental practices to treat more patients and to generate higher incomes for dental practices.

Less Physician Practice Competition Is Associated With Higher Prices Paid For Common Procedures.

PubMed

Austin, Daniel R; Baker, Laurence C

2015-10-01

Concentration among physician groups has been steadily increasing, which may affect prices for physician services. We assessed the relationship in 2010 between physician competition and prices paid by private preferred provider organizations for fifteen common, high-cost procedures to understand whether higher concentration of physician practices and accompanying increased market power were associated with higher prices for services. Using county-level measures of the concentration of physician practices and county average prices, and statistically controlling for a range of other regional characteristics, we found that physician practice concentration and prices were significantly associated for twelve of the fifteen procedures we studied. For these procedures, counties with the highest average physician concentrations had prices 8-26 percent higher than prices in the lowest counties. We concluded that physician competition is frequently associated with prices. Policies that would influence physician practice organization should take this into consideration.

A closer look at diagnosis in clinical dental practice: part 1. Reliability, validity, specificity and sensitivity of diagnostic procedures.

PubMed

Pretty, Iain A; Maupomé, Gerardo

2004-04-01

Dentists are involved in diagnosing disease in every aspect of their clinical practice. A range of tests, systems, guides and equipment--which can be generally referred to as diagnostic procedures--are available to aid in diagnostic decision making. In this era of evidence-based dentistry, and given the increasing demand for diagnostic accuracy and properly targeted health care, it is important to assess the value of such diagnostic procedures. Doing so allows dentists to weight appropriately the information these procedures supply, to purchase new equipment if it proves more reliable than existing equipment or even to discard a commonly used procedure if it is shown to be unreliable. This article, the first in a 6-part series, defines several concepts used to express the usefulness of diagnostic procedures, including reliability and validity, and describes some of their operating characteristics (statistical measures of performance), in particular, specificity and sensitivity. Subsequent articles in the series will discuss the value of diagnostic procedures used in daily dental practice and will compare today's most innovative procedures with established methods.

Cognitive load in distributed and massed practice in virtual reality mastoidectomy simulation.

Cognitive load theory states that working memory is limited. This has implications for learning and suggests that reducing cognitive load (CL) could promote learning and skills acquisition. This study aims to explore the effect of repeated practice and simulator-integrated tutoring on CL in virtual reality (VR) mastoidectomy simulation. Prospective trial. Forty novice medical students performed 12 repeated virtual mastoidectomy procedures in the Visible Ear Simulator: 21 completed distributed practice with practice blocks spaced in time and 19 participants completed massed practice (all practices performed in 1 day). Participants were randomized for tutoring with the simulator-integrated tutor function. Cognitive load was estimated by measuring reaction time in a secondary task. Data were analyzed using linear mixed models for repeated measurements. The mean reaction time increased by 37% during the procedure compared with baseline, demonstrating that the procedure placed substantial cognitive demands. Repeated practice significantly lowered CL in the distributed practice group but not in massed practice group. In addition, CL was found to be further increased by 10.3% in the later and more complex stages of the procedure. The simulator-integrated tutor function did not have an impact on CL. Distributed practice decreased CL in repeated VR mastoidectomy training more consistently than was seen in massed practice. This suggests a possible effect of skills and memory consolidation occurring over time. To optimize technical skills learning, training should be organized as time-distributed practice rather than as a massed block of practice, which is common in skills-training courses.

Ludden-Schlatter, Alicia; Wells, Jack; Kruse, Robin L

2018-06-01

Procedural training is integral to family medicine residencies. Although accreditation bodies require that family medicine residency programs train residents in procedures relevant to their practices, there are no standards defining the scope of family medicine. We compared the perceived importance of 31 procedures by faculty, residents, and recent graduates of one institution. An online survey was sent to current residents and faculty of a large academic family medicine residency, as well as community practitioners who had graduated from that residency within the past 5 years. The survey asked participants to rate how important 31 procedures are for family medicine practices. The overall response rate was 37%. Most respondents provided outpatient care, and few provided or intended to provide obstetric care. Dermatologic and musculoskeletal procedures were rated as having high importance by all groups, whereas obstetric and inpatient procedures received lower ratings. Residents ascribed higher importance than faculty or recent graduates for nearly all procedures. Most residents, faculty, and community practitioners provided outpatient care and rated dermatologic and musculoskeletal procedures as important. Inpatient and obstetric care are less common career paths, and related procedures were rated as less important. Resident physicians ascribed greater importance than community practitioners for many procedures, which may be due misperceptions of their future practice needs or imposed requirements for graduation.

Midwifery continuity of carer in an area of high socio-economic disadvantage in London: A retrospective analysis of Albany Midwifery Practice outcomes using routine data (1997-2009).

2017-05-01

in 1997, The Albany Midwifery Practice was established within King's College Hospital NHS Trust in a South East London area of high social disadvantage. The Albany midwives provided continuity of care to around 216 women per year, including those with obstetric, medical or social risk factors. In 2009, the Albany Midwifery Practice was closed in response to concerns about safety, amidst much publicity and controversy. The aim of this evaluation was to examine trends and outcomes for all mothers and babies who received care from the practice from 1997-2009. a retrospective, descriptive analysis of data routinely collected over the 12.5 year period was undertaken including changes over time and outcomes by demographic features. all women booked with the Albany Midwifery Practice were included. of the 2568 women included over the 12.5 year period, more than half (57%) were from Black, Asian and Minority Ethnic (BAME) communities; one third were single and 11.4% reported being single and unsupported. Almost all women (95.5%) were cared for in labour by either their primary or secondary midwife. There were high rates of spontaneous onset of labour (80.5%), spontaneous vaginal birth (79.8%), homebirth (43.5%), initiation of breastfeeding (91.5%) and breastfeeding at 28 days (74.3% exclusively and 14.8% mixed feeding). Of the 79% of women who had a physiological third stage, 5.9% had a postpartum haemorrhage. The overall rate of caesarean section was 16%. The preterm birth rate was low (5%). Ninety-five per cent of babies had an Apgar score of 8 or greater at 5minutes and 6% were admitted to a neonatal unit for more than two days. There were 15 perinatal deaths (perinatal mortality rate of 5.78 per 1000 births); two were associated with significant congenital abnormalities. There were no intrapartum intrauterine deaths. this analysis has shown that the Albany Midwifery Practice demonstrated positive outcomes for women and babies in socially disadvantaged and BAME groups, including those with complex pregnancies and perceived risk factors. consideration should be given to making similar models of care available to all women.

Considerations on the use of elastic wheels to the urban transport vehicles

NASA Astrophysics Data System (ADS)

Sebesan, Ioan; Arsene, Sorin; Manea, Ion

2018-03-01

To minimize dynamic wheel-rail interaction efforts a condition is that the unassembled mass of the vehicle is as small as possible. The elastic wheel by its construction fulfills these conditions - she has interposed between the crown and the body of the wheel, the elastic rubber elements. In this way, it can be considered that the unsupported mass is represented only by the mass of the wheel crown. Additionally, this elasticity also has a reduction effect on rolling noise. This feature makes it suitable for use on urban transport vehicles.

Removal of sulfur and nitrogen containing pollutants from discharge gases

DOEpatents

Joubert, James I.

1986-01-01

Oxides of sulfur and of nitrogen are removed from waste gases by reaction with an unsupported copper oxide powder to form copper sulfate. The resulting copper sulfate is dissolved in water to effect separation from insoluble mineral ash and dried to form solid copper sulfate pentahydrate. This solid sulfate is thermally decomposed to finely divided copper oxide powder with high specific surface area. The copper oxide powder is recycled into contact with the waste gases requiring cleanup. A reducing gas can be introduced to convert the oxide of nitrogen pollutants to nitrogen.

E-cigarette Regulation and Harm Reduction: The Case of Hong Kong.

PubMed

Churk, Shue Sing

Harm reduction is an internationally recognized tobacco control strategy. E-cigarettes, being a less harmful alternative to smoking, have the potential to achieve harm reduction. Within this context, this article critiques Hong Kong’s legal regime governing e-cigarettes and the proposed prohibition of the product. It is argued that the current law is uncertain and inadequate. Although a reform of laws relating to e-cigarettes is needed, it is argued that banning the product altogether as a means to reducing the harm of tobacco use is unsupported by evidence.

Development of flexible rotor balancing criteria

NASA Technical Reports Server (NTRS)

Walter, W. W.; Rieger, N. F.

1979-01-01

Several studies in which analytical procedures were used to obtain balancing criteria for flexible rotors are described. General response data for a uniform rotor in damped flexible supports were first obtained for plain cylindrical bearings, tilting pad bearings, axial groove bearings, and partial arc bearings. These data formed the basis for the flexible rotor balance criteria presented. A procedure by which a practical rotor in bearings could be reduced to an equivalent uniform rotor was developed and tested. It was found that the equivalent rotor response always exceeded to practical rotor response by more than sixty percent for the cases tested. The equivalent rotor procedure was then tested against six practical rotor configurations for which data was available. It was found that the equivalent rotor method offered a procedure by which balance criteria could be selected for practical flexible rotors, using the charts given for the uniform rotor.

It excludes other forms of music therapy. Several recommendations for practice are made. © 2011 Blackwell Publishing Asia Pty Ltd.

Rethinking family-centred care for the child and family in hospital.

PubMed

Tallon, Mary M; Kendall, Garth E; Snider, Paul D

2015-05-01

This paper presents and discusses an alternative model of family-centred care (FCC) that focuses on optimising the health and developmental outcomes of children through the provision of appropriate support to the child's family. The relevance, meaning and effectiveness of FCC have been challenged recently. Studies show that parents in hospital often feel unsupported, judged by hospital staff and uncertain about what care they should give to their child. With no convincing evidence relating FCC to improved child health outcomes, it has been suggested that FCC should be replaced with a new improved model to guide the care of children in hospital. This integrative review discusses theory and evidence-based literature that supports the practice of an alternative model of FCC that is focused on the health and developmental outcomes of children who are seriously ill, rather than the organisational requirements of children's hospitals. Theories and research findings in a wide range of disciplines including epidemiology, psychology, sociology, anthropology and neuroscience were accessed for this discussion. Nursing literature regarding partnership building, communication and FCC was also accessed. This paper discusses the benefits of applying a bioecological model of human development, the family and community resource framework, the concepts of allostatic load and biological embedding, empowerment theory, and the nurse-family partnership model to FCC. While there is no direct evidence showing that the implementation of this alternative model of FCC in the hospital setting improves the health and developmental outcomes of children who are seriously ill, there is a great deal of evidence from community nursing practice that suggests it is very likely to do so. Application of these theoretical concepts to practice has the potential to underpin a theory of nursing that is relevant for all nurses irrespective of the age of those they care for and the settings within which they work. © 2015 John Wiley & Sons Ltd.

[Prevention of medico-legal conflicts in medical practice].

PubMed

Minossi, José Guilherme

2009-02-01

Generally, medico-legal conflicts which occur in surgical and medical practice are a source of worry for both the medical profession and the society as a whole, because on one hand, they could cause high emotional stress for doctors, and on the other hand, patients could be rejected. Once consolidated, defensive medicine increases treatment costs and the doctor-patient relationship could transform into a tragedy. There are many causes for this, including non-treatment factors, such as an unsupported and disorganized health system, lack of participation from society and the doctor in improving this system, the training machine which launches a large number of young unprepared doctors to practice in this noble profession, along with a lack of continuing training, as there are few public or private institutions providing preparation, or further medical training. The related treatment factors are generally, a deficient doctor-patient relationship, poor work condition, power abuse by the doctor, a lack of clear agreement, and poor medical record keeping. These conflicts cannot be solved by simple creating legislation, or by denying the existence of medical error, which occurs at higher frequency than the actual conflicts. It is very important to improve the doctor-patient relationship because an effective fraternal relationship reduces the chance of a judicial demand. The doctor still needs to fully understand his/her conduct obligations and mainly to avoid power abuse. Doctors must also professionally link themselves with politicians who fight for the individual's rights against the system. Society must also understand that health is not just an issue exclusive for doctors, and people must fight to improve living conditions. Society must seriously show its frustration with the increasing disparity between scientific possibilities and actual wellbeing. The training machine needs immediate profound changes to produce professionals with the highest qualifications equipped for the needs of our population.

We evaluated historical patterns in the types of procedures performed in diagnostic and therapeutic nuclear medicine and the associated radiation safety practices used from 1945–2009 in a sample of U.S. radiologic technologists. In 2013–2014, 4,406 participants from the U.S. Radiologic Technologists (USRT) Study who previously reported working with medical radionuclides completed a detailed survey inquiring about the performance of 23 diagnostic and therapeutic radionuclide procedures and the use of radiation safety practices when performing radionuclide procedure-related tasks during five time periods: 1945–1964, 1965–1979, 1980–1989, 1990–1999, and 2000–2009. We observed an overall increase in the proportion of technologists who performed specific diagnostic or therapeutic procedures across the five time periods. Between 1945–1964 and 2000–2009, the median frequency of diagnostic procedures performed substantially increased (5 per week to 30 per week), attributable mainly to an increasing frequency of cardiac and non-brain PET scans, while the median frequency of therapeutic procedures performed modestly decreased (from 4 per month to 3 per month). We also observed a notable increase in the use of most radiation safety practices from 1945–1964 to 2000–2009 (e.g., use of lead-shielded vials during diagnostic radiopharmaceutical preparation increased from 56 to 96%), although lead apron use dramatically decreased (e.g., during diagnostic imaging procedures, from 81 to 7%). These data describe historical practices in nuclear medicine and can be used to support studies of health risks in nuclear medicine technologists. PMID:27218293

Newer treatment regimens for age-related macular degeneration have significantly affected traditional and non-traditional retinal services across all types of practice settings around the country as they seek to find a balance among delivering best patient care, keeping operating costs under control, and maintaining profitability. A systematic retrospective review of a multi-city, multi-physician retinal practice's accounting system to obtain data on revenues, expenses, and profit. Data reviewed were from practice management systems to obtain claims level data on clinical procedures across 7 primary activity centers: non-laser surgery, laser surgery, office visits, optical coherence tomography (OCT), non-OCT diagnostics, drugs and drug injections, and research. All treated patients from a retina practice from January 1, 2005, to December 31, 2007. Retrospective claims data review from a multi-physician retina practice detailing Current Procedural Terminology and Healthcare Common Procedure Coding System procedures performed and billed, submitted charges, allowed charges, and net collections. Analyses were performed by an outside firm and verified by a risk advisory firm. Identifying practice efficiencies/inefficiencies as they relate to patient care. An elaborate analysis using activity-based costing (ABC) showed that increased office visits and OCT and non-OCT diagnostics had a significant negative impact on the practice's profit margins, whereas surgical procedures contributed to the majority of the practice's profit margins because of the lower operating costs associated with surgery. The practice was able to accommodate the demand in patient volume, medical retina services, and medical imaging with the advent of anti-vascular endothelial growth factor therapy and realized a seismic shift in operating costs. The practice attempted to deliver state-of-the-art patient care in a cost-effective manner, yet underwent a significant decline in its financial health.

Implanon NXT: Expert tips for best-practice insertion and removal.

PubMed

Pearson, Suzanne; Stewart, Mary; Bateson, Deborah

2017-03-01

The single rod etonogestrel contraceptive implant is available in Australia as Implanon NXT. It is a highly effective, long-acting reversible contraceptive method, which is suitable for most women across the reproductive lifespan. This article provides practical advice for clinicians who already insert and remove the contraceptive implant, as well as advice for those who have not yet acquired this procedural skill. Contraceptive implant procedures are usually performed in the general practice setting. Clinicians can support women in making an informed choice to have an implant by providing information about their benefits, side effects and risks, and timely access to insertion. Training in the procedures and compliance with procedural instructions are essential to minimise risks, including deep insertion and damage to neurovascular structures.

Extravasation in a pediatric patient can cause a serious adverse event, but many nurses have insufficient experience to deal with it during intravenous administration. Our division implemented a best practice project, which included extravasation kit instruction preparation, staff education and an update of institutional policy and procedures. The project focused on auditing the extent to which the protocol was implemented and promoting its implementation. The objective of the project was to establish an evidence-based policy and procedure for extravasation management, improve knowledge regarding best practice of extravasation management among staff and formalize the documentation template for extravasation events. The Joanna Briggs Institute's Practical Application of Clinical Evidence System and Getting Research into Practice were used to examine compliance with criteria based on the best available evidence before and after the implementation of strategies to promote the use of the evidence-based practice protocol. Four criteria showed a noticeable improvement in compliance: increased use of extravasation kit (0-100%), updated policies and procedure (0-94%), staff education (19-94%) and documented outcomes (13-88%). The project successfully established effective strategies for establishing an extravasation kit instruction sheet, updating policies and procedures, continuous staff education and nursing documentation to ensure best practice and improve patient outcomes.

Female employees' perceptions of organisational support for breastfeeding at work: findings from an Australian health service workplace

PubMed Central

2011-01-01

Background Women's return to work can be a significant barrier to continued breastfeeding. Workplace policies and practices to promote and support continued, and longer duration of, breastfeeding are important. In the context of the introduction of a new breastfeeding policy for Area Health Services in New South Wales, Australia, a baseline survey was conducted to describe current practices and examine women's reports of perceived organisational support on breastfeeding intention and practice. Methods A cross sectional survey of female employees of the Sydney South West Area Health Service was conducted in late 2009. A mailed questionnaire was sent to 998 eligible participants who had taken maternity leave over the 20-month period from January 2008 to August 2009. The questionnaire collected items assessing breastfeeding intentions, awareness of workplace policies, and the level of organisational and social support available. For those women who had returned to work, further questions were asked to assess the perceptions and practices of breastfeeding in the work environment, as well as barriers and enabling factors to combining breastfeeding and work. Results Returning to work was one of the main reasons women ceased breastfeeding, with 60 percent of women intending to breastfeed when they returned to work, but only 40 percent doing so. Support to combine breastfeeding and work came mainly from family and partners (74% and 83% respectively), with little perceived support from the organisation (13%) and human resources (6%). Most women (92%) had received no information from their managers about their breastfeeding options upon their return to work, and few had access to a room specially designated for breastfeeding (19%). Flexible work options and lactation breaks, as well as access to a private room, were identified as the main factors that facilitate breastfeeding at work. Conclusions Enabling women to continue breastfeeding at work has benefits for the infant, employee and organisation. However, this baseline study of health employees revealed that women felt largely unsupported by managers and their organisation to continue breastfeeding at work. PMID:22129232

Standard operating procedures for clinical research departments.

PubMed

Kee, Ashley Nichole

2011-01-01

A set of standard operating procedures (SOPs) provides a clinical research department with clear roles, responsibilities, and processes to ensure compliance, accuracy, and timeliness of data. SOPs also serve as a standardized training program for new employees. A practice may have an employee that can assist in the development of SOPs. There are also consultants that specialize in working with a practice to develop and write practice-specific SOPs. Making SOPs a priority will save a practice time and money in the long run and make the research practice more attractive to corporate study sponsors.

Preoperative Planning in Orthopaedic Surgery. Current Practice and Evolving Applications.

PubMed

Atesok, Kivanc; Galos, David; Jazrawi, Laith M; Egol, Kenneth A

2015-12-01

Preoperative planning is an essential prerequisite for the success of orthopaedic procedures. Traditionally, the exercise has involved the written down, step by step "blueprint" of the surgical procedure. Preoperative planning of the technical aspects of the orthopaedic procedure has been performed on hardcopy radiographs using various methods such as copying the radiographic image on tracing papers to practice the planned interventions. This method has become less practical due to variability in radiographic magnification and increasing implementation of digital imaging systems. Advances in technology along with recognition of the importance of surgical safety protocols resulted in widespread changes in orthopaedic preoperative planning approaches. Nowadays, perioperative "briefings" have gained particular importance and novel planning methods have started to integrate into orthopaedic practice. These methods include using software that enables surgeons to perform preoperative planning on digital radiographs and to construct 3D digital models or prototypes of various orthopaedic pathologies from a patient's CT scans to practice preoperatively. Evidence-to-date suggests that preoperative planning and briefings are effective means of favorably influencing the outcomes of orthopaedic procedures.

Background The impact of specialization on the practice of general surgery has not been characterized. Our goal was to assess general surgeons’ operative practices to inform surgical education and workforce planning. Study Design We examined the practices of general surgeons identified in the 2008 State Inpatient and Ambulatory Surgery Databases of the Healthcare Cost and Utilization Project (HCUP) for three US states. Operations were identified using ICD-9 and CPT codes linked to encrypted physician identifiers. For each surgeon, total operative volume and the percentage of practice comprised of their most common operation were calculated. Correlation was measured between general surgeons’ case volume and the number of other specialists in a health service area. Results There were 1,075 general surgeons who performed 240,510 operations in 2008. The mean operative volume for each surgeon was 224 annual procedures. General surgeons performed an average of 23 different types of operations. For the majority of general surgeons, their most common procedure comprised no more than 30% of total practice. The most common operations, ranked by the frequency that they appeared as general surgeons’ top procedure, included: cholecystectomy, colonoscopy, endoscopy, and skin excision. The proportion of general surgery practice comprised of endoscopic procedures inversely correlated with the number of gastroenterologists in the health service area (Rho = - 0.50, p = 0.005). Conclusions Despite trends toward specialization, the current practices of general surgeons remain heterogeneous. This indicates a continued demand for broad-based surgical education to allow future surgeons to tailor their practices to their environment. PMID:24210145

Pediatricians' Attitudes and Beliefs about Long-Acting Reversible Contraceptives Influence Counseling.

PubMed

Berlan, Elise D; Pritt, Nicole M; Norris, Alison H

2017-02-01

Adolescents are at high risk for unintended pregnancy. Because of pediatricians' potential role in contraceptive counseling, understanding their attitudes and beliefs and counseling practices about use of long-acting reversible contraceptives (LARC; ie, etonogestrel implant and intrauterine devices [IUDs]) is vital. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We interviewed primary care pediatricians (N = 23) in a Midwestern city in June-August 2014. We transcribed the interviews, developed a coding schema, and analyzed these qualitative data using a priori and open coding of transcripts. Few pediatricians had favorable views on adolescent IUD use and most did not include IUDs in routine contraception counseling. Pediatricians perceived IUDs to impose significant risks for adverse reproductive outcomes and to be poorly tolerated by adolescents. Poor and/or outdated knowledge influenced inaccurate beliefs and unsupportive attitudes. Whereas some pediatricians were advocates for adolescent use of IUDs, many others had concerns that IUDs were not appropriate and not favored by adolescents. In contrast, participants viewed the etonogestrel implant more favorably and often included it in routine counseling. Some pediatricians focused on the familiar and readily available methods (injectable and oral contraceptives) or assumed patients had predetermined expectations for those methods. Time spent counseling on LARC was also perceived as a barrier. Pediatricians described how education and increased familiarity with LARC changed viewpoints. A variety of beliefs and attitudes, as well as factors such as time and personal habits, influence pediatricians' contraceptive counseling practices. Until knowledge deficits are addressed, uninformed viewpoints and unfavorable attitudes will limit adolescents' access to LARC, especially IUDs.

Social Support and Adherence for Military Veterans With Hepatitis C.

PubMed

Phillips, Frances H; Barnes, Donelle

2016-01-01

The aim of this study was to describe military veterans' experiences of support and how those experiences influence their decisions to be adherent, during hepatitis C virus (HCV) treatment. A qualitative phenomenological design was used. Inclusion criteria were veterans 18 years or older, receiving standard treatment for HCV, able to read, write, and communicate in English. A US Veterans Administration facility in Texas. Convenience sampling was used to obtain a final sample of 21 veterans. Data collection consisted of 1-time, in-depth interviews with analysis occurring simultaneously. Follow-up phone calls with participants verified that the themes were accurate reflections of their lived experience. Because of the fear of stigma, veterans make choices about to whom they tell their diagnosis. This limits the circle of friends and coworkers who could provide support. For some veterans, family members provide emotional and practical support, but family can also be a burden. In order to cope with family and treatment demands, some veterans hibernate, whereas others socialize with friends and coworkers. Some veterans found providers to be supportive, but others did not. Veterans experience both supportive and unsupportive reactions from family, friends, and healthcare providers while receiving HCV treatment. Those reactions either support or frustrate efforts to be adherent to treatment. In order to support treatment adherence, healthcare providers need to assess sources of support, or burden, experienced by military veterans during HCV treatment. When veterans do not have a supportive network, they need to be encouraged to attend a support group or seek counseling. Support services need to be funded by the Veterans Administration. Providers need to practice empathy and caring in order to support adherence during treatment. Further research is needed on how military veterans manage their health after hepatitis C treatment, contrasting successful versus unsuccessful treatment outcomes.

Mozambican midwives' views on barriers to quality perinatal care.

2006-02-01

Our purpose in this study was to explore the midwives' perception of factors obstructing or facilitating their ability to provide quality perinatal care at a central labor ward in Maputo. In-depth interviews were undertaken with 16 midwives and were analyzed according to grounded theory technique. Barriers to provision of quality perinatal care were identified as follows: (i) the unsupportive environment, (ii) nonempowering and limited interaction with women in labor, (iii) a sense of professional inadequacy and inferiority, and (iv) nonappliance of best caring practices. A model based on the midwives' reflections on barriers to quality perinatal care and responses to these were developed. Actions aimed at overcoming the barriers were improvising and identifying areas in need of change. Identified evading actions were holding others accountable and yielding to dysfunction and structural control. In order to improve perinatal care, the midwives need to see themselves as change agents and not as victims of external and internal causal relationships over which they have no influence. It is moreover essential that the midwives chose actions aiming at overcoming barriers to quality perinatal care instead of choosing evading actions, which might jeopardize the health of the unborn and newborn infant. We suggest that local as well as national education programs need to correspond with existing reality, even if they provide knowledge that surpasses the present possibilities in practice. Quality of intrapartum and the immediate newborn care requires a supportive environment, however, which in the context of this study presented such serious obstacles that they need to be addressed on the national level. Structural and administrative changes are difficult to target as these depend on national organization of maternal health care (MHC) services and national health expenditures.

A qualitative exploration of how midwives' and obstetricians' perception of risk affects care practices for low-risk women and normal birth.

PubMed

Maternity care is facing increasing intervention and iatrogenic morbidity rates. This can be attributed, in part, to higher-risk maternity populations, but also to a risk culture in which birth is increasingly seen as abnormal. Technology and intervention are used to prevent perceived implication in adverse outcomes and litigation. Does midwives' and obstetricians' perception of risk affect care practices for normal birth and low-risk women in labour, taking into account different settings? The research methods are developed within a qualitative framework. Data were collected using semi-structured interviews and analysed thematically. A purposive sample of 25 midwives and obstetricians were recruited from three maternity settings in Ireland. This included obstetric-led hospitals, an alongside midwifery-led unit and the community. Midwifery is assuming a peripheral position with regard to normal birth as a progressive culture of risk and medicalisation affects the provision of maternity care. This is revealed in four themes; (1) professional autonomy and hierarchy in maternity care; (2) midwifery-led care as an undervalued and unsupported aspiration; (3) a shift in focus from striving for normality to risk management; and (4) viewing pregnancy through a 'risk-lens'. Factors connected to the increased medicalisation of birth contribute to the lack of midwifery responsibility for low-risk women and normal birth. Midwives are resigned to the current situation and as a profession are reluctant to take action. Improved models of care, distinct from medical jurisdiction, are required. Midwives must take responsibility for leading change as their professional identity is in jeopardy. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Degradation of learned skills: Effectiveness of practice methods on visual approach and landing skill retention

NASA Technical Reports Server (NTRS)

Sitterley, T. E.; Zaitzeff, L. P.; Berge, W. A.

1972-01-01

Flight control and procedural task skill degradation, and the effectiveness of retraining methods were evaluated for a simulated space vehicle approach and landing under instrument and visual flight conditions. Fifteen experienced pilots were trained and then tested after 4 months either without the benefits of practice or with static rehearsal, dynamic rehearsal or with dynamic warmup practice. Performance on both the flight control and procedure tasks degraded significantly after 4 months. The rehearsal methods effectively countered procedure task skill degradation, while dynamic rehearsal or a combination of static rehearsal and dynamic warmup practice was required for the flight control tasks. The quality of the retraining methods appeared to be primarily dependent on the efficiency of visual cue reinforcement.

Stability of the Orca Basin Brine Interface Determined Using Radium Isotopes

NASA Astrophysics Data System (ADS)

Peterson, R. N.; Peterson, L.; Montoya, J. P.; Joye, S. B.

2016-02-01

The Orca Basin is an intraslope basin in the northern continental slope of the Gulf of Mexico, and contains a deep (up to 220 m) anoxic, hypersaline brine lake. The brine interface extends from ocean salinity (at a water depth of 2125 m) to a constant salinity of 215 psu below a depth of 2250 m. This interface is considered to be among the most stable interfaces on the planet, and contains distinct zones of macrofaunal and microbial assemblages. The brine lake is supported by continued dissolution of exposed rock salt at an estimated rate of 0.5 million t/yr. Such dissolution of salt should serve as a source of radium isotopes, and given their range of half-lives, these isotopes can serve as unique proxies to the location and rate of salt dissolution into this basin. We have collected a series of radon and radium isotope profiles through this brine lake over the past 4 years, which allow us to assess the spatial and temporal stability of this interface. Throughout the brine lake, we observe strong enrichments in unsupported Ra-224, Rn-222, and Ra-226 in a 10 m thick zone near the base of the brine interface, between 2232 m and 2242 m. The strong enrichment in unsupported Ra-224 in this layer must be supported by a continuous source, presumably the dissolution of exposed salt rock. Various degrees of isotopic enrichment throughout the lake provide an assessment of the rates of lateral and vertical dispersion of salt and associated chemical constituents.

Mobile Phone Use Behaviors and Postures on Public Transportation Systems.

Mobile phones are common in our daily life, but the users' preferences for postures or screen operating styles have not been studied. This was a cross-sectional and observational study. We randomly sampled passengers who used mobile phones on the Mass Rapid Transit (MRT) system in metropolitan Taipei. A checklist was used to observe their body postures and screen operating styles while sitting or standing. As a result, 1,230 subjects from 400 trips were observed. Overall, of all the passengers who were sitting, 41% of them were using mobile phones. The majority of the tasks involved browsing (84%) with their phones in a portrait orientation (93%). Different-hand holding/operating was the most commonly used operating style while sitting (46%) and same-hand holding/operating was the most common while standing (46%). The distribution of screen operating styles was significantly different for those sitting than for those standing and for different genders and age groups. The most frequently observed postures while sitting were having one's trunk against a backrest, feet on the floor and with or without an arm supported (58%). As for the users who were standing, the both- and different-hands groups had a high proportion of arms unsupported, feet on the floor and either their trunk supported or not. In contrast, the same-hand group tended to have their trunk unsupported, were holding a pole or handstrap and had both feet on floor. Further studies are warranted to characterize the ergonomic exposure of these commonly used postures and operating styles, and our results will help guide the selection of experimental conditions for laboratory settings.

Partner support and anxiety in young women with breast cancer.

Using a large prospective cohort of women age 40 or younger diagnosed with breast cancer, we examined the relationship between perceived partner support and anxiety. Six hundred seventy-five young women with breast cancer Stages I-III, median age 36, completed a self-report baseline questionnaire. Perceived partner support was assessed using items extracted from the marital subscale of the Cancer Rehabilitation Evaluation System; generalized social support was assessed with the Medical Outcomes Study-Social Support Survey. Anxiety was measured using the anxiety subscale of the Hospital Anxiety and Depression Scale. Multivariable logistic regression analyses evaluated the association between partner support, other sociodemographic factors, and anxiety. Mean age at diagnosis was 35.4 years. Fourteen percent of the women were not partnered, and among those who were partnered or in a significant relationship, 20% were categorized as unsupported. In univariate and multivariable analysis adjusting for sociodemographic factors, women in an unsupported-partnered relationship had higher odds of anxiety symptoms compared with women in a supported-partnered relationship. Young age and being financially insecure were also both independently associated with anxiety. Our findings suggest that partner support may play a key role in a young woman's adjustment to a serious stressor such as breast cancer. In addition, younger age increases vulnerability to anxiety as does struggling with finances. Because supportive efforts of a partner have potential to protect against the impact of stress, interventions to enhance partner support and reduce anxiety might be beneficial to address challenges experienced as a couple in this setting.

Northcott, Sarah; Hirani, Shashivadan P; Hilari, Katerina

2018-05-08

Social network typologies have been used to classify the general population but have not previously been applied to the stroke population. This study investigated whether social network types remain stable following a stroke, and if not, why some people shift network type. We used a mixed methods design. Participants were recruited from two acute stroke units. They completed the Stroke Social Network Scale (SSNS) two weeks and six months post stroke and in-depth interviews 8-15 months following the stroke. Qualitative data was analysed using Framework Analysis; k-means cluster analysis was applied to the six-month data set. Eighty-seven participants were recruited, 71 were followed up at six months, and 29 completed in-depth interviews. It was possible to classify all 29 participants into one of the following network types both prestroke and post stroke: diverse; friends-based; family-based; restricted-supported; restricted-unsupported. The main shift that took place post stroke was participants moving out of a diverse network into a family-based one. The friends-based network type was relatively stable. Two network types became more populated post stroke: restricted-unsupported and family-based. Triangulatory evidence was provided by k-means cluster analysis, which produced a cluster solution (for n = 71) with comparable characteristics to the network types derived from qualitative analysis. Following a stroke, a person's social network is vulnerable to change. Explanatory factors for shifting network type included the physical and also psychological impact of having a stroke, as well as the tendency to lose contact with friends rather than family.

What are the Facilitators and Obstacles to Participation in Workplace Team Sport? A Qualitative Study

PubMed Central

Brinkley, Andrew; Freeman, Josie; McDermott, Hilary; Munir, Fehmidah

2017-01-01

Working age adults are failing to meet physical activity recommendations. Inactive behaviours are increasing costs for diminished individual and organisational health. The workplace is a priority setting to promote physical activity, however there is a lack of evidence about why some employees choose to participate in novel workplace activities, such as team sport, whilst others do not. The aim of this study was to explore the complexity of facilitators and obstacles associated with participation in workplace team sport. Twenty-nine semi-structured face-to-face and telephone interviews were conducted with office workers (58% female) (36 ± 7.71) from manufacturing, public services, and educational services. Data was analysed through template analysis. Five sub-level (i.e., intrapersonal, interpersonal, organisational, community and societal influences) facilitate participation or create obstacles for participants. Participants were challenged by a lack of competence, self-efficacy, negative sporting ideals and amotivation. Unhealthy competition, an unstable work-life balance and unsupportive colleagues created obstacles to participation. An unsupportive organisation and workplace culture placed demands on workplace champions, funding, facilities and communication. Healthy competitions, high perceptions of competence and self-efficacy, and being motivated autonomously enabled participation. Further, relatedness and social support created a physical activity culture where flexible working was encouraged and team sport was promoted in accessible locations within the organisation. Researchers should consider accounting for complexity of these influences. A participatory approach may tailor interventions to individual organisations and the employees that work within them. Interventions whereby autonomy, competence and relatedness are supported are recommended. This may be achieved by adapting sports and training workplace champions. PMID:29922705

(1) Integrate practice-based patient encounters using the Dartmouth Atlas Medicare database to understand practice treatments for Ménière's disease (MD). (2) Describe differences in the practice patterns between academic and community providers for MD. Practice-based research database review. CHEER (Creating Healthcare Excellence through Education and Research) network academic and community providers. MD patient data were identified with ICD-9 and CPT codes. Demographics, unique visits, and procedures per patient were tabulated. The Dartmouth Atlas of Health Care was used to reference regional health care utilization. Statistical analysis included 1-way analyses of variance, bivariate linear regression, and Student's t tests, with significance set at P < .05. A total of 2071 unique patients with MD were identified from 8 academic and 10 community otolaryngology-head and neck surgery provider centers nationally. Average age was 56.5 years; 63.9% were female; and 91.4% self-reported white ethnicity. There was an average of 3.2 visits per patient. Western providers had the highest average visits per patient. Midwest providers had the highest average procedures per patient. Community providers had more visits per site and per patient than did academic providers. Academic providers had significantly more operative procedures per site (P = .0002) when compared with community providers. Health care service areas with higher total Medicare reimbursements per enrollee did not report significantly more operative procedures being performed. This is the first practice-based clinical research database study to describe MD practice patterns. We demonstrate that academic otolaryngology-head and neck surgery providers perform significantly more operative procedures than do community providers for MD, and we validate these data with an independent Medicare spending database. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Variability in Accreditation Council for Graduate Medical Education Resident Case Log System practices among orthopaedic surgery residents.

PubMed

Salazar, Dane; Schiff, Adam; Mitchell, Erika; Hopkinson, William

2014-02-05

The Accreditation Council for Graduate Medical Education (ACGME) Resident Case Log System is designed to be a reflection of residents' operative volume and an objective measure of their surgical experience. All operative procedures and manipulations in the operating room, Emergency Department, and outpatient clinic are to be logged into the Resident Case Log System. Discrepancies in the log volumes between residents and residency programs often prompt scrutiny. However, it remains unclear if such disparities truly represent differences in operative experiences or if they are reflections of inconsistent logging practices. The purpose of this study was to investigate individual recording practices among orthopaedic surgery residents prior to August 1, 2011. Orthopaedic surgery residents received a questionnaire on case log practices that was distributed through the Council of Orthopaedic Residency Directors list server. Respondents were asked to respond anonymously about recording practices in different clinical settings as well as types of cases routinely logged. Hypothetical scenarios of common orthopaedic procedures were presented to investigate the differences in the Current Procedural Terminology codes utilized. Two hundred and ninety-eight orthopaedic surgery residents completed the questionnaire; 37% were fifth-year residents, 22% were fourth-year residents, 18% were third-year residents, 15% were second-year residents, and 8% were first-year residents. Fifty-six percent of respondents reported routinely logging procedures performed in the Emergency Department or urgent care setting. Twenty-two percent of participants routinely logged procedures in the clinic or outpatient setting, 20% logged joint injections, and only 13% logged casts or splints applied in the office setting. There was substantial variability in the Current Procedural Terminology codes selected for the seven clinical scenarios. There has been a lack of standardization in case-logging practices among orthopaedic surgery residents prior to August 1, 2011. ACGME case log data prior to this date may not be a reliable measure of residents' procedural experience.

MCM-41 support for ultrasmall γ-Fe 2O 3 nanoparticles for H 2S removal

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

Cara, C.; Rombi, E.; Musinu, A.

In this paper, MCM-41 is proposed to build mesostructured Fe 2O 3-based sorbents as an alternative to other silica or alumina supports for mid-temperature H 2S removal. MCM-41 was synthesized as micrometric (MCM41_M) and nanometric (MCM41_N) particles and impregnated through an efficient two-solvent (hexane–water) procedure to obtain the corresponding γ-Fe 2O 3@MCM-41 composites. The active phase is homogeneously dispersed within the 2 nm channels in the form of ultrasmall maghemite nanoparticles assuring a high active phase reactivity. The final micrometric (Fe_MCM41_M) and nanometric (Fe_MCM41_N) composites were tested as sorbents for hydrogen sulphide removal at 300 °C and the results weremore » compared with a reference sorbent (commercial unsupported ZnO) and an analogous silica-based sorbent (Fe_SBA15). MCM-41 based sorbents, having the highest surface areas, showed superior performances that were retained after the first sulphidation cycle. Specifically, the micrometric sorbent (Fe_MCM41_M) showed a higher SRC value than the nanometric one (Fe_MCM41_N), due to the low stability of the nanosized particles over time caused by their high reactivity. Finally and furthermore, the low regeneration temperature (300–350 °C), besides the high removal capacity, renders MCM41-based systems an alternative class of regenerable sorbents for thermally efficient cleaning up processes in Integrated Gasification Combined Cycles (IGCC) systems.« less

An analysis of leading, lagging, and coincident economic indicators in the United States and its relationship to the volume of plastic surgery procedures performed.

PubMed

Hoppe, Ian C; Pastor, Craig J; Paik, Angie M

2012-10-01

In plastic surgery, 2 predominant practice environments exist, namely, the academic setting and private practice. These 2 groups cater their practice toward the needs and demands of 2 very different patient populations. The goal of this paper is to examine well-established economic indicators and delineate their relationship, if any, with the volume of different plastic surgical procedures performed in the United States. Information from the American Society of Plastic Surgeons' annual reports on plastic surgery statistics was collected from the year 2000 through 2010 and compared to readily available and established economic indicators. There was a significant positive relationship with total cosmetic procedures and gross domestic product (GDP), GDP per capita, personal income, consumer price index (CPI) (all), and CPI (medical). There was a significant positive relationship between cosmetic surgical procedures and the issuance of new home permits and the average prime rate charged by banks. There was a significant positive relationship with cosmetic minimally invasive procedures and GDP, GDP per capita, personal income, CPI (all), and CPI (medical). There was a significant negative relationship between reconstructive procedures and GDP, GDP per capita, personal income, CPI (all), and CPI (medical). Cosmetic minimally invasive procedures seem to be decided on relatively quickly during good economic times. Cosmetic surgical procedures seem to be more planned and less related to the economic environment. The plastic surgeon may use this relationship to tailor the focus of his or her practice to be best situated for economic fluctuations.

Procedural and short-term safety of bronchial thermoplasty in clinical practice: evidence from a national registry and Hospital Episode Statistics.

Bronchial thermoplasty (BT) is a novel treatment for severe asthma. Its mode of action and ideal target patient group remain poorly defined, though clinical trials provided some evidence on efficacy and safety. This study presents procedural and short-term safety evidence from routine UK clinical practice. Patient characteristics and safety outcomes (procedural complications, 30-day readmission and accident and emergency (A&E) attendance, length of stay) were assessed using two independent data sources, the British Thoracic Society UK Difficult Asthma Registry (DAR) and Hospital Episodes Statistics (HES) database. A matched cohort (with records in both) was used to estimate safety outcome event rates and compare them with clinical trials. Between June 2011 and January 2015, 215 procedure records (83 patients; 68 treated in England) were available from DAR and 203 (85 patients) from HES. 152 procedures matched (59 patients; 6 centres), and of these, 11.2% reported a procedural complication, 11.8% resulted in emergency respiratory readmission, 0.7% in respiratory A&E attendance within 30 days (20.4% had at least one event) and 46.1% involved a post-procedure stay. Compared with published clinical trials which found lower hospitalisation rates, BT patients in routine clinical practice were, on average, older, had worse baseline lung function and asthma quality of life. A higher proportion of patients experienced adverse events compared with clinical trials. The greater severity of disease amongst patients treated in clinical practice may explain the observed rate of post-procedural stay and readmission. Study of long-term safety and efficacy requires continuing data collection.

A procedure to evaluate environmental rehabilitation in limestone quarries.

PubMed

Neri, Ana Claudia; Sánchez, Luis Enrique

2010-11-01

A procedure to evaluate mine rehabilitation practices during the operational phase was developed and validated. It is based on a comparison of actually observed or documented practices with internationally recommended best practices (BP). A set of 150 BP statements was derived from international guides in order to establish the benchmark. The statements are arranged in six rehabilitation programs under three categories: (1) planning (2) operational and (3) management, corresponding to the adoption of the plan-do-check-act management systems model to mine rehabilitation. The procedure consists of (i) performing technical inspections guided by a series of field forms containing BP statements; (ii) classifying evidences in five categories; and (iii) calculating conformity indexes and levels. For testing and calibration purposes, the procedure was applied to nine limestone quarries and conformity indexes were calculated for the rehabilitation programs in each quarry. Most quarries featured poor planning practices, operational practices reached high conformity levels in 50% of the cases and management practices scored moderate conformity. Despite all quarries being ISO 14001 certified, their management systems pay low attention to issues pertaining to land rehabilitation and biodiversity. The best results were achieved by a quarry whose expansion was recently submitted to the environmental impact assessment process, suggesting that public scrutiny may play a positive role in enhancing rehabilitation practices. Conformity indexes and levels can be used to chart the evolution of rehabilitation practices at regular intervals, to establish corporate goals and for communication with stakeholders.

Review of musculoskeletal injuries and prevention in the endoscopy practitioner.

PubMed

Harvin, Glenn

2014-08-01

Practitioners of endoscopy often experience musculoskeletal pain and injury (most often in the back, neck, shoulders, hands, wrists, and thumbs) that are associated with the minute and repetitive strain that is placed on these areas during endoscopic procedures. This review of the current documentation of endoscopy-related pain and injuries among practitioners finds that such problems are widespread and specific in kind as well as strongly correlated with high procedure volume and procedure duration. Research on the nature and impact of cumulative trauma and overuse syndromes in other professions such as dentistry, pianists, production labor, and athletics is brought to bear on the work of the endoscopist. A more thorough understanding of the nature and prevalence of work-related pain and injury sustained by endoscopists should inform further development of ergonomic practices and equipment design. This article reviews current recommendations for ergonomic design in the endoscopy procedure space and finds that reported compliance with those recommendations is quite low. Strategies for the management of the risk of musculoskeletal injuries related to the practice of endoscopy include compliance with currently recommended ergonomic practices, education of trainees in ergonomic technique when practicing endoscopy, and research toward the modification and development of more ergonomic endoscopes and procedure spaces.

An evaluation of periodontal assessment procedures among Indiana dental hygienists.

PubMed

Stephan, Christine A

2014-01-01

Using a descriptive correlational design, this study surveyed periodontal assessment procedures currently performed by Indiana dental hygienists in general dentistry practices to reveal if deficiencies in assessment exist. Members (n = 354) of the Indiana Dental Hygienists' Association (IDHA) were invited to participate in the survey. A 22 multiple choice question survey, using Likert scales for responses, was open to participants for three weeks. Descriptive and non-parametric inferential statistics analyzed questions related to demographics and assessment procedures practiced. In addition, an evaluation of the awareness of periodontal assessment procedures recommended by the American Academy of Periodontology (AAP) was examined. Of the 354 Indiana dental hygienists surveyed, a 31.9% response rate was achieved. Participants were asked to identify the recommended AAP periodontal assessment procedures they perform. The majority of respondents indicated either frequently or always performing the listed assessment procedures. Additionally, significant relationships were found between demographic factors and participants' awareness and performance of recommended AAP assessment procedures. While information gathered from this study is valuable to the body of literature regarding periodontal disease assessment, continued research with larger survey studies should be conducted to obtain a more accurate national representation of what is being practiced by dental hygienists.

The impact of specialization on the practice of general surgery has not been characterized. Our goal was to assess general surgeons' operative practices to inform surgical education and workforce planning. We examined the practices of general surgeons identified in the 2008 State Inpatient and Ambulatory Surgery Databases of the Healthcare Cost and Utilization Project for 3 US states. Operations were identified using ICD-9 and CPT codes linked to encrypted physician identifiers. For each surgeon, total operative volume and percentage of practice that made up their most common operation were calculated. Correlation was measured between general surgeons' case volume and the number of other specialists in a health service area. There were 1,075 general surgeons who performed 240,510 operations in 2008. The mean operative volume for each surgeon was 224 annual procedures. General surgeons performed an average of 23 different types of operations. For the majority of general surgeons, their most common procedure constituted no more than 30% of total practice. The most common operations, ranked by the frequency they appeared as general surgeons' top procedure, included cholecystectomy, colonoscopy, endoscopy, and skin excision. The proportion of general surgery practice composed of endoscopic procedures inversely correlated with the number of gastroenterologists in the health service area (rho = -0.50; p = 0.005). Despite trends toward specialization, the current practices of general surgeons remain heterogeneous. This indicates a continued demand for broad-based surgical education to allow future surgeons to tailor their practices to their environment. Copyright © 2014 American College of Surgeons.

Myths, fallacies and practical pearls in GI lab

PubMed Central

Kumar, Pradeep

2014-01-01

Many prevalent practices and guidelines related to Gastrointestinal endoscopy and procedural sedation are at odds with the widely available scientific-physiological and clinical outcome data. In many institutions, strict policy of pre-procedural extended fasting is still rigorously enforced, despite no evidence of increased incidence of aspiration after recent oral intake prior to sedation. Supplemental oxygen administration in the setting of GI procedural sedation has been increasingly adopted as reported in the medical journals, despite clear evidence that supplemental oxygen blunts the usefulness of pulse oximetry in timely detection of sedation induced hypoventilation, leading to increased number of adverse cardiopulmonary outcomes. Use of Propofol by Gastroenterologist-Nurse team is erroneously considered dangerous and often prohibited in various institutions, at the same time worldwide reports of remarkable safety and patient satisfaction continue to be published, dating back more than a decade. Of patient monitoring practices that have been advocated to be standard, many merely add cost, not value. Advances in the technology often are not incorporated in a timely manner in guidelines or clinical practices, e.g., Capsule endoscopy or electrocautery during GI procedures do not interfere with proper functioning of the current pacemakers or defibrillators. Orthopedic surgeons have continued to recommend prophylactic antibiotics for joint replacement patients prior to GI procedures, without any evidence of need. These myths are explored for a succint review to prompt a change in clinical practices and institutional policies. PMID:25512767

Assessment of the scope of practice of physicians participating in the Mais Médicos (More Doctors) Program, and associated factors.

The purpose of this study was to characterize the scope of practice of physicians working in primary healthcare participating in the Mais Médicos (More Doctors) Program ('PMM') and investigate the factors associated with execution of a larger number of clinical activities. It is an exploratory study carried over January to March 2016, through a self-applied questionnaire containing a list of 49 procedures, activities and actions carried out in primary healthcare. A total of 1,241 physicians took part in the study, most of them female, between age 40 and 49, and of Cuban nationality. The physicians carried out an average of 22.8 ± 8.2 procedures; they reported knowing how to carry out a larger number of procedures. Factors associated with executing a larger number of procedures were: being male, having graduated more recently, two years or less practicing in their primary healthcare unit, practicing in the North or South geographical regions, in small towns and more distant from the regional health headquarters. The main reason for not carrying out the procedures and activities that they reported knowing how to do was the lack of materials and inadequate infrastructure. The results show that the scope of practice of the physicians of the PMM is lower than their capacities, and that interventions with the intention of widening their scope are necessary.

The legal and ethical implications of consent to nursing procedures.

PubMed

Power, K J

Nurses are increasingly expanding their practice to include many more invasive procedures. Consequently, there is a need to re-examine nurses' responsibilities in relation to obtaining consent for nursing as opposed to medical procedures. Fully informed consent is not a legal requirement in England, for either medical or nursing procedures. However, this article argues that to comply with the standard set by the Code of Professional Conduct nurses should obtain informed consent for any proposed procedure they undertake. The concept of informed consent is examined and applied to practice. Ultimately, nurses are charged with four key tasks in relation to securing consent for nursing procedures: educating themselves about the risks and benefits of the procedures they propose to undertake; conveying this information to patients; assessing their understanding of the information given; and endeavouring to support the patient in his/her decision.

Perceptions of transcatheter device closure of patent ductus arteriosus in veterinary cardiology and evaluation of a canine model to simulate device placement: a preliminary study.

The purpose of this study was to evaluate a canine patent ductus arteriosus (PDA) model developed for practicing device placement and to determine practices and perceptions regarding transcatheter closure of PDA from the veterinary cardiology community. A silicone model was developed from images obtained from a dog with a PDA and device placement was performed with catheter equipment and a document camera to simulate fluoroscopy. A total of 36 individuals including 24 diplomates and 12 residents participated, and the feedback was obtained. The study included an initial questionnaire, practice with the model, observation of device placement using the model, and a follow-up questionnaire. A total of 92% of participants including 100% of residents indicated they did not have the opportunity to practice device placement before performing the procedure and obtained knowledge of the procedure from reading journal articles or observation. Participants indicated selecting the appropriate device size (30/36, 83%) and ensuring the device is appropriately positioned before release (18/36, 50%) as the most common areas of difficulty with device placement. Confidence level was higher after practicing with the model for residents when compared with diplomates and for participants that had performed 1-15 procedures when compared with those that had performed >15 procedures. These findings suggest those that have performed fewer procedures may benefit the most from practicing with a model. This preliminary study demonstrates the feasibility of a PDA model for practicing device placement and suggests that there is a potential benefit from providing additional training resources.

Rolling-cuff flexible bellows

DOEpatents

Lambert, D.R.

1982-09-27

A flexible connector apparatus used to join two stiff non-deformable members, such as piping, is described. The apparatus is provided with one or more flexible sections or assemblies each utilizing a bellows of a rolling cuff type connected between two ridge members, with the bellows being supported by a back-up ring, such that only the curved end sections of the bellows are unsupported. Thus, the bellows can be considered as being of a tube-shaped configuration and thus have high pressure resistance. The components of the flexible apparatus are sealed or welded one to another such that it is fluid tight.

New law requires 'medically accurate' lesson plans.

PubMed

1999-09-17

The California Legislature has passed a bill requiring all textbooks and materials used to teach about AIDS be medically accurate and objective. Statements made within the curriculum must be supported by research conducted in compliance with scientific methods, and published in peer-reviewed journals. Some of the current lesson plans were found to contain scientifically unsupported and biased information. In addition, the bill requires material to be "free of racial, ethnic, or gender biases." The legislation is supported by a wide range of interests, but opposed by the California Right to Life Education Fund, because they believe it discredits abstinence-only material.
