2013-08-01

The additive and interactive relations of parenting styles (authoritative and authoritarian parenting) and child temperament (anger/frustration, sadness, and effortful control) to children's internalizing problems were examined in a 3.8-year longitudinal study of 425 Chinese children (aged 6-9 years) from Beijing. At Wave 1, parents self-reported on their parenting styles, and parents and teachers rated child temperament. At Wave 2, parents, teachers, and children rated children's internalizing problems. Structural equation modeling indicated that the main effect of authoritative parenting and the interactions of Authoritarian Parenting × Effortful Control and Authoritative Parenting × Anger/Frustration (parents' reports only) prospectively and uniquely predicted internalizing problems. The above results did not vary by child sex and remained significant after controlling for co-occurring externalizing problems. These findings suggest that (a) children with low effortful control may be particularly susceptible to the adverse effect of authoritarian parenting and (b) the benefit of authoritative parenting may be especially important for children with high anger/frustration.

Development and validation of a scale to measure perceived control of internal states.

PubMed

Pallant, J F

2000-10-01

One of the key developments in the psychological literature on control has been the growing recognition of the multidimensional nature of the control construct. Recent research suggests that perceived control of internal states may be just as important as perceived control of external events. The Perceived Control of Internal States Scale was developed to provide a measure of the degree to which people feel they have control of their internal states (emotions, thoughts, physical reactions). I report the results of 2 studies (N= 689), supporting the reliability, construct, and incremental validity of the scale. The buffering effects of perceived control for people facing major life events was also explored, with higher levels of perceived control being associated with less physical and psychological symptoms of strain.

Many of the cognitive behavioral models and therapeutic protocols developed so far for psychological disorders and chronic diseases have proved effective through clinical research. This study aimed to determine the effectiveness of teaching cognitive-behavioral techniques on locus of control in hemodialysis patients. This controlled clinical trial study was conducted in 2015 with 76 patients selected by census and treated with a hemodialysis machine in the dialysis department of Vali-Asr Hospital in the city of Meshkinshahr. A total of four patients were excluded because of their critical conditions while the rest, who were recruited, were randomly divided into two equal groups of 36 patients as the intervention and control groups. First, the locus of control was measured in both groups through a pretest, and cognitive-behavioral techniques were then taught to the intervention group during eight 45 to 90-minute sessions. The locus of control in patients of both groups was finally re-measured through a posttest. Data were collected using Rotter's Locus of Control Inventory. The Wilcoxon test and Mann-Whitney U test were respectively used in SPSS18 for data analysis. In the pretest and posttest stages respectively, 4.8% and 14.3% of samples in the control group as well as 14.3% and 33.3% of samples in the intervention group enjoyed internal locus of control. The difference between the pretest and posttest scores of internal locus of control in the intervention group was significant (p=0.004), which indicates the positive effect of cognitive-behavioral psychotherapeutic intervention on internalization of locus of control in this group. Given the external locus of control in most of the study patients and also the positive significant effect of cognitive-behavioral psychotherapy on internalization of locus of control in this group of patients, it appears necessary to have a psychology resident present in the hemodialysis department to teach the necessary cognitive-behavioral techniques to internalize the locus of control. The trial was registered at the Thai Clinical Trial Registry (http://www.clinicaltrials.in.th) with the TCTID: TCTR20170707003.

The effect of high and low assertiveness on locus of control and health problems was examined with 78 direct-service workers in mental health and mental retardation settings in northeastern Pennsylvania. The direct-service workers completed the Rathus (1973) Assertiveness Schedule, the Rotter (1966) Internal-External Locus of Control Scale, and a health-problems inventory. Highly assertive individuals were found to be more internally controlled and to experience fewer health problems than were individuals low in assertiveness.

2009-01-01

Adolescent girls with body dissatisfaction (N=481; SD=1.4) were randomized to a dissonance-based thin-ideal internalization reduction program, healthy weight control program, expressive-writing control condition, or assessment-only control condition. Dissonance participants showed significantly greater decreases in thin-ideal internalization, body dissatisfaction, negative affect, eating disorder symptoms, and psychosocial impairment, and lower risk for eating pathology onset through 2–3 year follow-up than assessment-only controls. Dissonance participants showed greater decreases in thin-ideal internalization, body dissatisfaction, and psychosocial impairment than expressive-writing controls. Healthy weight participants showed greater decreases in thin-ideal internalization, body dissatisfaction, negative affect, eating disorder symptoms, and psychosocial impairment, less increases in weight, and lower risk for eating pathology and obesity onset through 2–3 year follow-up than assessment-only controls. Healthy weight participants showed greater decreases in thin-ideal internalization and weight than expressive writing controls. Dissonance participants showed a 60% reduction in risk for eating pathology onset and healthy weight participants showed a 61% reduction in risk for eating pathology onset and a 55% reduction in risk for obesity onset relative to assessment-only controls through 3-year follow-up, implying that the effects are clinically important and enduring.

To examine the cost-effectiveness of a nurse practitioner-family physician model of care compared with family physician-only care in a Canadian nursing home. As demand for long-term care increases, alternative care models including nurse practitioners are being explored. Cost-effectiveness analysis using a controlled before-after design. The study included an 18-month 'before' period (2005-2006) and a 21-month 'after' time period (2007-2009). Data were abstracted from charts from 2008-2010. We calculated incremental cost-effectiveness ratios comparing the intervention (nurse practitioner-family physician model; n = 45) to internal (n = 65), external (n = 70) and combined internal/external family physician-only control groups, measured as the change in healthcare costs divided by the change in emergency department transfers/person-month. We assessed joint uncertainty around costs and effects using non-parametric bootstrapping and cost-effectiveness acceptability curves. Point estimates of the incremental cost-effectiveness ratio demonstrated the nurse practitioner-family physician model dominated the internal and combined control groups (i.e. was associated with smaller increases in costs and emergency department transfers/person-month). Compared with the external control, the intervention resulted in a smaller increase in costs and larger increase in emergency department transfers. Using a willingness-to-pay threshold of $1000 CAD/emergency department transfer, the probability the intervention was cost-effective compared with the internal, external and combined control groups was 26%, 21% and 25%. Due to uncertainty around the distribution of costs and effects, we were unable to make a definitive conclusion regarding the cost-effectiveness of the nurse practitioner-family physician model; however, these results suggest benefits that could be confirmed in a larger study. © 2016 John Wiley & Sons Ltd.

To evaluate the role of common internal controls in a meta-analysis of the relative efficacy of cyclooxygenase 2-selective inhibitors (coxibs) in the treatment of osteoarthritis (OA). A systematic search of Medline and US Food and Drug Administration electronic databases was performed to identify randomized, placebo-controlled clinical trials of coxibs (etoricoxib, celecoxib, rofecoxib, valdecoxib) in patients with hip and/or knee OA. The effect size for coxibs and common active internal controls (nonsteroidal antiinflammatory drugs [NSAIDs], naproxen) were determined by the mean changes from baseline in Western Ontario and McMaster Universities Osteoarthritis Index pain subscores as compared with placebo. The effect size for all coxib groups combined (0.44) indicated greater efficacy as compared with placebo, but significant heterogeneity (P < 0.0001) was observed. Rofecoxib at dosages of 12.5 mg/day and 25 mg/day and etoricoxib at a dosage of 60 mg/day had similar effect sizes (0.68 and 0.73, respectively), but these effect sizes were comparatively greater than those for both celecoxib at dosages of 200 mg/day and 100 mg twice daily or valdecoxib at a dosage of 10 mg/day (0.26 and 0.16, respectively). The effect sizes for NSAIDs or naproxen versus placebo, as determined using data from rofecoxib/etoricoxib trials, were consistently higher than the effect sizes derived from trials of celecoxib/valdecoxib. Significant heterogeneity was present in the overall effect size for NSAIDs (P = 0.007) and naproxen (P = 0.04) groups based on data available from all coxib trials. Coxibs and common active internal controls showed larger effect sizes versus placebo in the rofecoxib/etoricoxib trials than in the celecoxib/valdecoxib trials. These findings suggest systematic differences among published coxib trials and emphasize the need for direct-comparison trials. In the absence of such trials, common internal controls should be assessed when performing indirect meta-analytic comparisons.

An attitude of gratitude: The effects of body-focused gratitude on weight bias internalization and body image.

2018-06-01

Internalized weight bias and body dissatisfaction are associated with a number of negative psychological and physical health outcomes. The current study examined the effectiveness of body-focused gratitude, through a short writing exercise, as a strategy to reduce internalized weight bias and improve body image. Young adults (M age  = 22.71, SD = 2.08, 51.2% female) were randomly assigned to either a body gratitude condition (n = 185) or a control condition (n = 184). Results indicated that participants in the gratitude condition reported significantly lower weight bias internalization and significantly more favorable appearance evaluation and greater body satisfaction when compared to the control condition. These effects were in the small range (ds = 0.27-0.33), and neither gender nor BMI moderated these effects. These findings provide preliminary support for body-focused gratitude writing exercises as an effective individual-level strategy for both reducing internalized weight bias and improving body image.

Model Predictive Control of the Current Profile and the Internal Energy of DIII-D Plasmas

NASA Astrophysics Data System (ADS)

Lauret, M.; Wehner, W.; Schuster, E.

2015-11-01

For efficient and stable operation of tokamak plasmas it is important that the current density profile and the internal energy are jointly controlled by using the available heating and current-drive (H&CD) sources. The proposed approach is a version of nonlinear model predictive control in which the input set is restricted in size by the possible combinations of the H&CD on/off states. The controller uses real-time predictions over a receding-time horizon of both the current density profile (nonlinear partial differential equation) and the internal energy (nonlinear ordinary differential equation) evolutions. At every time instant the effect of every possible combination of H&CD sources on the current profile and internal energy is evaluated over the chosen time horizon. The combination that leads to the best result, which is assessed by a user-defined cost function, is then applied up until the next time instant. Simulations results based on a control-oriented transport code illustrate the effectiveness of the proposed control method. Supported by the US DOE under DE-FC02-04ER54698 & DE-SC0010661.

External and semi-internal controls for PCR amplification of homologous sequences in mixed templates.

PubMed

Kalle, Elena; Gulevich, Alexander; Rensing, Christopher

2013-11-01

In a mixed template, the presence of homologous target DNA sequences creates environments that almost inevitably give rise to artifacts and biases during PCR. Heteroduplexes, chimeras, and skewed template-to-product ratios are the exclusive attributes of mixed template PCR and never occur in a single template assay. Yet, multi-template PCR has been used without appropriate attention to quality control and assay validation, in spite of the fact that such practice diminishes the reliability of results. External and internal amplification controls became obligatory elements of good laboratory practice in different PCR assays. We propose the inclusion of an analogous approach as a quality control system for multi-template PCR applications. The amplification controls must take into account the characteristics of multi-template PCR and be able to effectively monitor particular assay performance. This study demonstrated the efficiency of a model mixed template as an adequate external amplification control for a particular PCR application. The conditions of multi-template PCR do not allow implementation of a classic internal control; therefore we developed a convenient semi-internal control as an acceptable alternative. In order to evaluate the effects of inhibitors, a model multi-template mix was amplified in a mixture with DNAse-treated sample. Semi-internal control allowed establishment of intervals for robust PCR performance for different samples, thus enabling correct comparison of the samples. The complexity of the external and semi-internal amplification controls must be comparable with the assumed complexity of the samples. We also emphasize that amplification controls should be applied in multi-template PCR regardless of the post-assay method used to analyze products. © 2013 Elsevier B.V. All rights reserved.

Background Many of the cognitive behavioral models and therapeutic protocols developed so far for psychological disorders and chronic diseases have proved effective through clinical research. Objective This study aimed to determine the effectiveness of teaching cognitive-behavioral techniques on locus of control in hemodialysis patients. Methods This controlled clinical trial study was conducted in 2015 with 76 patients selected by census and treated with a hemodialysis machine in the dialysis department of Vali-Asr Hospital in the city of Meshkinshahr. A total of four patients were excluded because of their critical conditions while the rest, who were recruited, were randomly divided into two equal groups of 36 patients as the intervention and control groups.

The difference between the pretest and posttest scores of internal locus of control in the intervention group was significant (p=0.004), which indicates the positive effect of cognitive-behavioral psychotherapeutic intervention on internalization of locus of control in this group. Conclusions Given the external locus of control in most of the study patients and also the positive significant effect of cognitive-behavioral psychotherapy on internalization of locus of control in this group of patients, it appears necessary to have a psychology resident present in the hemodialysis department to teach the necessary cognitive-behavioral techniques to internalize the locus of control.

Parenting behavior dimensions and child psychopathology: specificity, task dependency, and interactive relations.

PubMed

Caron, Annalise; Weiss, Bahr; Harris, Vicki; Catron, Tom

2006-02-01

This study examined the specificity of relations between parent or caregiver behaviors and childhood internalizing and externalizing problems in a sample of 70 fourth-grade children (64% boys, M age = 9.7 years). Specificity was assessed via (a) unique effects, (b) differential effects, and (c) interactive effects. When measured as unique and differential effects, specificity was not found for warmth or psychological control but was found for caregiver's use of behavior control. Higher levels of behavior control were uniquely related to lower levels of externalizing problems and higher levels of internalizing problems; differential effects analyses indicated that higher levels of behavior control were related to decreases in the within-child difference in relative levels of level of internalizing versus externalizing problems. Interactive relations among the 3 parenting behavior dimensions also were identified. Although caregivers emphasized different parenting behavior dimensions across 2 separate caregiver-child interaction tasks, relations between parenting behavior dimensions and child psychopathology did not vary as a function of task. These findings indicate the importance of assessing and simultaneously analyzing multiple parenting behavior dimensions and multiple child psychopathology domains.

[The significance of the relationship between external/internal locus of control and adolescent substance use in behavioral medicine].

2011-02-27

Prevention and treatment of the addictions are key public health priorities in modern society. In medical practice, in relation to the biochemical processes, mapping the addiction-prone personality traits, like external/internal locus of control are getting more and more attention. Individuals with high level on internal locus of control, for example, tend to take care of their health behavior; the lack of it, on the other hand, may worsen the effectiveness of stress release which may increase the likelihood of turning to substance use. The main goal of the present study was to investigate the relationship between adolescent substance use (both lifetime prevalence and the actual substance user status) and external/internal locus of control). The data collection of the questionnaire survey was going on among 656 high school students in Szeged (age range between 14-21 years, mean = 16.5 years, S.D. = 1.5 years of age, 49.1% of the sample was female). Associations between indicators of substance use (as dependent variables) and scale points of external/internal locus of control (as independent variables) were assessed using odds ratios calculated by logistic regression analyses, whereas gender was used as a controlling variable. Among boys, scale points of external, among girls, those of internal locus of control showed higher values. External locus of control increased, whereas internal locus of control decreased the risk of substance use, however, the relative role of external/internal locus of control was different according to the type of substance use and the prevalence values. In terms of smoking, lifetime prevalence, whereas in terms of marijuana use, the actual user status was influenced. In addition, while the latter one was also affected by gender, it did not play a role at all in the previous one. All these findings suggest that behavioral control may play a particularly important role in prevention of adolescent substance use. For developing this, methods of cognitive therapy would be effective to be completed with autogenic relaxation training as well.

The Effects of Religion and Locus of Control on Perception of Mental Illness.

Amedome, Sedem Nunyuia; Bedi, Innocent Kwame

2018-06-23

The study investigated the influence of religion and locus of control on perception of mental illness. Specifically, the study explored the relationship between religiosity and perception of mental illness, differences in perception by internals and externals, the effect of knowledge on perception of mental illness and the interactive effect of religiosity and locus of control on perception of mental illness. Data were collected from 200 participants in the Volta Region of Ghana. Three hypotheses were tested in the study using a battery of tests. It was observed that people with internal locus of control perceive mental patients positively than those with external locus of control. A significant interactive effect between religiosity and locus of control on perception of mental illness was observed. Religiosity significantly relates to perception of mental illness. The results and implications are discussed for further studies.

Locus of control as a stress moderator and mediator in children of divorce.

PubMed

Kim, L S; Sandler, I N; Tein, J Y

1997-04-01

This paper examined the stress moderator and mediator effects of four dimensions of perceived control in children of divorce. The dimensions of locus of control included internal control for positive events, internal control for negative events, unknown control for positive events, and unknown control for negative events. The sample consisted of 222 children between the ages of 8 and 12 whose parents had divorced in the previous 2 years. Moderational analyses showed that unknown control for positive events interacted with negative events to predict total symptoms. Plots of the simple slopes indicated a stress buffering effect whereby the slope of negative events on symptoms was higher for high than for low levels of unknown control for positive events. Mediational analysis showed that the relations between negative events and symptoms were mediated by both unknown control for positive events and unknown control for negative events. In contrast, evidence was not found for either a stress mediational or a moderational model for perceived internal control for positive or negative events. These results suggest that unknown control beliefs may be a particularly important dimension of control for children of divorce.

Resistance to temptation: the interaction of external and internal control on alcohol use during residential treatment for alcohol use disorder.

There is evidence that drinking during residential treatment is related to various factors, such as patients' general control beliefs and self-efficacy, as well as to external control of alcohol use by program's staff and situations where there is temptation to drink. As alcohol use during treatment has been shown to be associated with the resumption of alcohol use after discharge from residential treatment, we aimed to investigate how these variables are related to alcohol use during abstinence-oriented residential treatment programs for alcohol use disorders (AUD). In total, 509 patients who entered 1 of 2 residential abstinence-oriented treatment programs for AUD were included in the study. After detoxification, patients completed a standardized diagnostic procedure including interviews and questionnaires. Drinking was assessed by patients' self-report of at least 1 standard drink or by positive breathalyzer testing. The 2 residential programs were categorized as high or low control according to the average number of tests per patient. Regression analysis revealed a significant interaction effect between internal and external control suggesting that patients with high internal locus of control and high frequency of control by staff demonstrated the least alcohol use during treatment (16.7%) while patients with low internal locus of control in programs with low external control were more likely to use alcohol during treatment (45.9%). No effects were found for self-efficacy and temptation. As alcohol use during treatment is most likely associated with poor treatment outcomes, external control may improve treatment outcomes and particularly support patients with low internal locus of control, who show the highest risk for alcohol use during treatment. High external control may complement high internal control to improve alcohol use prevention while in treatment. Copyright © 2015 The Authors.

Affiliation with weight conscious peer groups is theorized to increase thin-ideal internalization through socialization processes. However, selection effects could contribute if genetic and/or environmental predispositions lead to affiliation with weight conscious peers. Co-twin control methodology was used to examine socialization and selection effects in 614 female twins (ages 8–15) from the Michigan State University Twin Registry (MSUTR). Thin-ideal internalization and peer group characteristics were assessed via self-report questionnaires. Results suggested the presence of both socialization and selection effects. In terms of socialization, twins who reported increased exposure to weight conscious peers relative to their co-twins had elevated thin-ideal internalization scores, regardless of zygosity. However, associations between weight conscious peers and thin-ideal internationalization within twin pairs were attenuated, suggesting that genetic and shared environmental selection effects also contribute. Findings significantly extend previous work by confirming the presence of socialization processes and highlighting selection processes to be examined in future longitudinal research. PMID:26859605

We examined whether cognitive control moderates the effects of emotion on adolescent internalizing and externalizing symptomatology in a longitudinal study of 138 adolescents. Self-reported positive affect (PA) and negative affect and behavioral and neural indicators of cognitive control, indexed by performance and prefrontal hemodynamic response during a cognitive interference task, were collected at Time 1. Self-reported internalizing and externalizing symptomatology were collected at Time 1 and Time 2 (1 year later). Results indicated that higher PA predicted decreases in externalizing symptomatology, but only for adolescents with poor neural cognitive control. No moderation effects were found for behavioral cognitive control. Findings imply the beneficial effects of PA on the development of externalizing problems among adolescents with poor prefrontal functioning. © 2018 Society for Research on Adolescence.

We investigated the links between familial loading, preadolescent temperament, and internalizing and externalizing problems in adolescence, hereby distinguishing effects on maladjustment in general versus dimension-specific effects on either internalizing or externalizing problems. In a population-based sample of 2230 preadolescents (10-11 years) familial loading (parental lifetime psychopathology) and offspring temperament were assessed at baseline by parent report, and offspring psychopathology at 2.5-years follow-up by self-report, teacher report and parent report. We used purified measures of temperament and psychopathology and partialled out shared variance between internalizing and externalizing problems. Familial loading of internalizing psychopathology predicted offspring internalizing but not externalizing problems, whereas familial loading of externalizing psychopathology predicted offspring externalizing but not internalizing problems. Both familial loadings were associated with Frustration, low Effortful Control, and Fear. Frustration acted as a general risk factor predicting severity of maladjustment; low Effortful Control and Fear acted as dimension-specific risk factors that predicted a particular type of psychopathology; whereas Shyness, High-Intensity Pleasure, and Affiliation acted as direction markers that steered the conditional probability of internalizing versus externalizing problems, in the event of maladjustment. Temperament traits mediated one-third of the association between familial loading and psychopathology. Findings were robust across different composite measures of psychopathology, and applied to girls as well as boys. With regard to familial loading and temperament, it is important to distinguish general risk factors (Frustration) from dimension-specific risk factors (familial loadings, Effortful Control, Fear), and direction markers that act as pathoplastic factors (Shyness, High-Intensity Pleasure, Affiliation) from both types of risk factors. About one-third of familial loading effects on psychopathology in early adolescence are mediated by temperament.

2018-06-01

We used a multigroup propensity score approach to evaluate a randomized effectiveness trial of the New Beginnings Program (NBP), an intervention targeting divorced or separated families. Two features of effectiveness trials, high nonattendance rates and inclusion of an active control, make program effects harder to detect. To estimate program effects based on actual intervention participation, we created a synthetic inactive control comprised of nonattenders and assessed the impact of attending the NBP or active control relative to no intervention (inactive control). We estimated propensity scores using generalized boosted models and applied inverse probability of treatment weighting for the comparisons. Relative to the inactive control, NBP strengthened parenting quality as well as reduced child exposure to interparental conflict, parent psychological distress, and child internalizing problems. Some effects were moderated by parent gender, parent ethnicity, or child age. On the other hand, the effects of active versus inactive control were minimal for parenting and in the unexpected direction for child internalizing problems. Findings from the propensity score approach complement and enhance the interpretation of findings from the intention-to-treat approach.

The effects of computer-assisted instruction and locus of control upon preservice elementary teachers' acquisition of the integrated science process skills

Wesley, Beth Eddinger; Krockover, Gerald H.; Devito, Alfred

The purpose of this study was to determine the effects of computer-assisted instruction (CAI) versus a text mode of programmed instruction (PI), and the cognitive style of locus of control, on preservice elementary teachers' achievement of the integrated science process skills. Eighty-one preservice elementary teachers in six sections of a science methods class were classified as internally or externally controlled. The sections were randomly assigned to receive instruction in the integrated science process skills via a microcomputer or printed text. The study used a pretest-posttest control group design. Before assessing main and interaction effects, analysis of covariance was used to adjust posttest scores using the pretest scores. Statistical analysis revealed that main effects were not significant. Additionally, no interaction effects between treatments and loci of control were demonstrated. The results suggest that printed PI and tutorial CAI are equally effective modes of instruction for teaching internally and externally oriented preservice elementary teachers the integrated science process skills.

Nonlinearity measure and internal model control based linearization in anti-windup design

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

2013-12-18

This paper considers the problem of internal model control based linearization in anti-windup design. The nonlinearity measure concept is used for quantifying the control system degree of nonlinearity. The linearizing effect of a modified internal model control structure is presented by comparing the nonlinearity measures of the open-loop and closed-loop systems. It is shown that the linearization properties are improved by increasing the control system local feedback gain. However, it is emphasized that at the same time the stability of the system deteriorates. The conflicting goals of stability and linearization are resolved by solving the design problem in different frequencymore » ranges.« less

Recent studies have investigated alternatives to warfarin for stroke prophylaxis in patients with atrial fibrillation (AF), but whether these alternatives are cost-effective is unknown. On the basis of the results from Randomized Evaluation of Long Term Anticoagulation Therapy (RE-LY) and other trials, we developed a decision-analysis model to compare the cost and quality-adjusted survival of various antithrombotic therapies. We ran our Markov model in a hypothetical cohort of 70-year-old patients with AF using a cost-effectiveness threshold of $50 000/quality-adjusted life-year. We estimated the cost of dabigatran as US $9 a day. For a patient with an average risk of major hemorrhage (≈3%/y), the most cost-effective therapy depended on stroke risk. For patients with the lowest stroke rate (CHADS2 stroke score of 0), only aspirin was cost-effective. For patients with a moderate stroke rate (CHADS2 score of 1 or 2), warfarin was cost-effective unless the risk of hemorrhage was high or quality of international normalized ratio control was poor (time in the therapeutic range <57.1%). For patients with a high stroke risk (CHADS(2) stroke score ≥3), dabigatran 150 mg (twice daily) was cost-effective unless international normalized ratio control was excellent (time in the therapeutic range >72.6%). Neither dabigatran 110 mg nor dual therapy (aspirin and clopidogrel) was cost-effective. Dabigatran 150 mg (twice daily) was cost-effective in AF populations at high risk of hemorrhage or high risk of stroke unless international normalized ratio control with warfarin was excellent. Warfarin was cost-effective in moderate-risk AF populations unless international normalized ratio control was poor.

2005-01-01

The present experimental research examined whether framing early adolescents' (11- to 12-year-olds) learning activity in terms of the attainment of an extrinsic (i.e., physical attractiveness) versus intrinsic (i.e., health) goal and communicating these different goal contents in an internally controlling versus autonomy-supportive way affect performance. Both conceptual and rote learning were assessed. Three experimental field studies, 2 among obese and 1 among nonobese participants, confirmed the hypothesis that extrinsic goal framing and internal control undermine conceptual (but not rote) learning, even in comparison with a control group. Study 3 indicated that the positive effect of intrinsic goal framing on conceptual learning was mediated by task involvement, whereas the positive effect of autonomy-supportive communication style on conceptual learning was mediated by relative autonomous motivation.

2013-09-01

To identify the international philanthropies that have invested in tobacco control in China, describe their role and strategies in changing the social norms of tobacco use, and define the outcomes achieved. Information on the international philanthropic donor China projects, including activities and outcomes, was gathered from multiple sources including organisational websites, key informant interviews and emails with project officers, and published research papers and reports. Philanthropic donations to China's tobacco control efforts began in 1986. The donors provided funds to national, city, provincial government organisations, non-government organisations, universities, and healthcare organisations throughout China to establish a tobacco control workforce and effective programmes to reduce the burden of tobacco use. International engagement has been an important dimension of tobacco control in China. Recognising the large burden of illness and capitalising on proven effective control measures, philanthropic organisations understandably seized the opportunity to achieve major health gains. Much of the international philanthropic investment has been directed at public information, policy change and building the Chinese research knowledge base. Documenting research and evaluation findings will continue to be important to ensure that promising practices and lessons learned are identified and shared with the China tobacco control practitioners. The ultimate question is whether foreign philanthropy is making a difference in tobacco control and changing social norms in China? The answer is plainly and simply that we do not know; the evidence is not yet available.

The effects of internal and external control factors on college students' marijuana use and cessation of use.

PubMed

Lo, C C; Globetti, G

1995-01-01

The purpose of this study was to examine how selected internal and external control variables influence lifetime use, frequency of use, and cessation of use of marijuana. The internal control factor, comprising the variables 1) perceived risk of marijuana use and 2) attitudes toward prohibition of marijuana use, refers to a built-in personal tendency toward conventionality. The external control factor refers to social-environmental forces which discourage marijuana use. External control is indicated by factors including the number of extra-curricular activities in which an individual is involved; place of residence; the availability of marijuana; peer attitudes toward marijuana use; the number of an individual's friends who use marijuana; and the number of occasions on which an individual has observed others using marijuana. The study's results show that both internal and external control factors are significant predictors of the frequency of marijuana use. The external control factor, however, plays a more important role in explaining lifetime marijuana use and cessation of marijuana use.

To evaluate the effectiveness on the prevention of behavior problems of life skills education combining school-based and parent-involved approaches for third-grade students in China. This research was targeted at the population of third-grade children in two elementary schools in Qinhuangdao City, Hebei Province. Nine regular school classrooms were randomly divided into three groups: the intervention group (n=208), internal control group (n=209) and external control group (n=204). The intervention included 26-hour competence promotion for students and 5-hour parent training. The Rutter Scale by parent and teacher were used to evaluate the effects at pretest, posttest and 6-month follow-up. Improvement was observed among children in the intervention group than those in the control groups. The statistical difference was significant (P<0.05).1.The prevalence of total behavior problems, antisocial behavior and neurotic behavior problem at home: At termination, the prevalence in intervention group(11.2%,3.6% and 6.1%)was lower (except neurotic behavior) than those in internal control group (19.4%,5.6% and 6.1%)and external control group (18.9%,8.9% and 5.3%). At 6-month follow-up, the prevalence in intervention group (10.2%,2.5% and 3.6%)was still lower than those in internal control group (17.2%,6.8% and 6.8%)and external control group (17.8%,7.8% and 6.7%).2. The prevalence of total behavior problems and antisocial behavior problem at school: At termination, the prevalence in intervention group(5.3% and 4.3%)was lower than those in internal control group(10.1% and 7.7%)and external control group(14.9% and 12.4%). At 6-month follow-up, the prevalence in intervention group(2.9% and 2.4%)was still lower than those in internal control group (10.2% and 9.7%)and external control group(11.3% and 10.3%). Life skills education could reduce the children's home and school behavior problems, especially for antisocial behavior. The effects of intervention maintained during the 6-month follow-up study.

The longitudinal stability and control characteristics of a 1/30-scale model of the Republic XF-103 airplane were investigated in the Langley 8-foot transonic tunnel. The effect of speed brakes located at the end of the fuselage was also investigated. The main part of the investigation was made with internal flow in the model, but some data were obtained with no internal flow. The longitudinal stability and control at transonic-speeds appeared satisfactory. The transonic drag rise was small. The speed brakes had no adverse effects on longitudinal stability.

Although work stress can impede the capacity of direct support professionals and contribute to mental health challenges, external (i.e. work social support) and internal resources (i.e. an internal locus of control) have been shown to help DSPs cope more actively. We examined how work stress was associated with depression, with a particular focus on the role of resources. Direct support professionals (n = 323) who serve adults with intellectual and developmental disabilities from five community-based organisations completed a cross-sectional, self-administered survey which measured work stress, work support, locus of control, and depression. Multiple regression analyses demonstrated that work stress was positively associated with depression, while resources were negatively associated with depression. In particular, work support moderated the effects of client disability stress, supervisory support lessened the effects of role conflict, and locus of control moderated the effects of workload. Such findings suggest the importance of external and internal resources for staff mental health. This research underscores the need for strong work social support systems and interventions to help staff manage work stressors.

2018-05-21

Over 24 million international visitors came to Japan in 2016 and the number is expected to increase. Visitors could be at a risk of illness or injury that may result in hospitalization in Japan. We assessed the effects of a four-minute digital animation titled Mari Info Japan on the level of anxiety experienced by international visitors to Japan. We conducted a non-randomized, controlled study at Narita International Airport outside Tokyo in December 2014. On the first day, we recruited international visitors for the intervention group at predetermined departure gates and, the following day, we sampled visitors for the control group at the same gates. We repeated this procedure twice over 4 days. The intervention group watched the digital animation and the control group read a standard travel guidebook in English. After receiving either intervention, they completed a questionnaire on their level of anxiety. The outcome was assessed using the Mari Meter-X, The State-Trait Anxiety Inventory Form Y (STAI-Y), and a face scale, before and immediately after the intervention. We analyzed data with Wilcoxon rank sum tests. We recruited 265 international visitors (134 in the intervention group, 131 in the control group), 241 (91%) of whom completed the questionnaire. Most of them had no previous Japanese health information before arrival in Japan. The level of anxiety about health services in Japan was significantly reduced in the intervention group (Mari Meter-X median: - 5 and 0, p < 0.001 and STAI-Y median: - 3 and 0, p < 0.001). The face scale analysis showed no significant difference. Watching a digital animation is more effective in reducing anxiety among international visitors to Japan compared with reading a standard brochure or guidebook. Such effective animations of health information should be more widely distributed to international visitors.

Shehata, Ahmed W; Scheme, Erik J; Sensinger, Jonathon W

2018-05-01

On-going developments in myoelectric prosthesis control have provided prosthesis users with an assortment of control strategies that vary in reliability and performance. Many studies have focused on improving performance by providing feedback to the user but have overlooked the effect of this feedback on internal model development, which is key to improve long-term performance. In this paper, the strength of internal models developed for two commonly used myoelectric control strategies: raw control with raw feedback (using a regression-based approach) and filtered control with filtered feedback (using a classifier-based approach), were evaluated using two psychometric measures: trial-by-trial adaptation and just-noticeable difference. The performance of both strategies was also evaluated using Schmidt's style target acquisition task. Results obtained from 24 able-bodied subjects showed that although filtered control with filtered feedback had better short-term performance in path efficiency ( ), raw control with raw feedback resulted in stronger internal model development ( ), which may lead to better long-term performance. Despite inherent noise in the control signals of the regression controller, these findings suggest that rich feedback associated with regression control may be used to improve human understanding of the myoelectric control system.

The effects of caudal mobilisation with movement (MWM) and caudal self-mobilisation with movement (SMWM) in relation to restricted internal rotation in the hip: A randomised control pilot study.

PubMed

Walsh, Riche; Kinsella, Sharon

2016-04-01

A loss of internal rotation (IR) of the hip is associated with hip pathology. Improving IR may improve hip range of motion (ROM) or prevent hip pathology. The purpose of this study was to compare the immediate effects of caudal mobilisation with movement (MWM) and caudal self-mobilisation with movement (SMWM) on young healthy male subjects with reduced IR of the hip. A randomised controlled trial was performed. Twenty-Two subjects were randomised into a MWM group (n = 6), SMWM group (n = 8) or a control group (n = 8). The primary outcome measures included the functional internal rotation test (FIRT) for the hip and the passive seated internal rotation test (SIRT) for the hip. Outcomes were captured at baseline and immediately after one treatment of MWMs, SMWMs or control. A two-way analysis of variance (ANOVA), group × time interaction was conducted. The ANOVA revealed the only significant improvement was in the MWM group for the FIRT (p = 0.01), over the control group. Subjects with reduced IR of the hip who receive a single session of MWMs exhibited significantly improved functional IR of their hip than the control group. From the data presented, it can be suggested that caudal MWMs of the hip appear to have a positive effect on functional IR of healthy young hips. This may be due to addressing the positional fault theory or the arthrogenic muscular inhibition theory. SMWMs may be effective in augmenting treatments for patients waiting for hip operations.

Startle stimuli reduce the internal model control in discrete movements.

PubMed

Wright, Zachary A; Rogers, Mark W; MacKinnon, Colum D; Patton, James L

2009-01-01

A well known and major component of movement control is the feedforward component, also known as the internal model. This model predicts and compensates for expected forces seen during a movement, based on recent experience, so that a well-learned task such as reaching to a target can be executed in a smooth straight manner. It has recently been shown that the state of preparation of planned movements can be tested using a startling acoustic stimulus (SAS). SAS, presented 500, 250 or 0 ms before the expected "go" cue resulted in the early release of the movement trajectory associated with the after-effects of the force field training (i.e. the internal model). In a typical motor adaptation experiment with a robot-applied force field, we tested if a SAS stimulus influences the size of after-effects that are typically seen. We found that in all subjects the after-effect magnitudes were significantly reduced when movements were released by SAS, although this effect was not further modulated by the timing of SAS. Reduced after-effects reveal at least partial existence of learned preparatory control, and identify startle effects that could influence performance in tasks such as piloting, teleoperation, and sports.

The effects of pictorially displayed information on human learning and performance of a simple control task were investigated. The controlled system was a harmonic oscillator and the system response was displayed to subjects as either an animated pendulum or a horizontally moving dot. Results indicated that the pendulum display did not effect performance scores but did significantly effect the learning processes of individual operators. The subjects with the pendulum display demonstrated more vertical internal models early in the experiment and the manner in which their internal models were tuned with practice showed increased variability between subjects.

Existing systematic reviews provide evidence that music therapy is an effective intervention in the treatment of children and adolescents with psychopathology. The objective of the present review was to systematically review and quantify the effects of music-based interventions in reducing internalizing symptoms (i.e., depression and anxiety) in children and adolescents using a meta-analytical approach. Databases and journals were systematically screened for studies eligible for inclusion in meta-analysis on the effects of music-based interventions in reducing internalizing symptoms. A random-effect meta-analysis using standardized mean differences (SMD) was conducted. Five studies were included. Analysis of data from (randomized) controlled trials, yielded a significant main effect (Hedge's g = -0.73; 95%CI [-1.42;-0.04], Z = 2.08, p = 0.04, k = 5), indicating a greater reduction of internalizing symptoms in youth receiving music-based interventions (n = 100) compared to different control group interventions (n = 95). The existing evidence is limited to studies of low power and methodological quality. Included studies were highly heterogeneous with respect to the nature of the intervention, the measurements applied, the samples studied, and the study design. Findings indicate that music-based interventions may be efficient in reducing the severity of internalizing symptoms in children and adolescents. While these results are encouraging with respect to the application of music-based intervention, rigorous research is necessary to replicate existing findings and provide a broader base of evidence. More research adopting well controlled study designs of high methodological quality is needed. Copyright © 2017 Elsevier B.V. All rights reserved.

2010-01-01

This experiment examined whether jury-eligible community members (N = 223) were able to detect internally invalid psychological science presented at trial. Participants read a simulated child sexual abuse case in which the defense expert described a study he had conducted on witness memory and suggestibility. We varied the study's internal validity (valid, missing control group, confound, and experimenter bias) and publication status (published, unpublished). Expert evidence quality ratings were higher for the valid versus missing control group version only. Publication increased ratings of defendant guilt when the study was missing a control group. Variations in internal validity did not influence perceptions of child victim credibility or police interview quality. Participants' limited detection of internal validity threats underscores the need to examine the effectiveness of traditional legal safeguards against junk science in court and improve the scientific reasoning ability of lay people and legal professionals.

There is little knowledge about how emotional regulation contributes to vulnerability versus resilience to substance use disorder. With younger adolescents, we studied the pathways through which emotion regulation attributes are related to predisposing factors for disorder. A sample of 3561 adolescents (M age 12.5 years) was surveyed. Measures for emotional self-control (regulation of sadness and anger), emotional dysregulation (angerability, affective lability, and rumination about sadness or anger), and behavioral self-control (planfulness and problem solving) were obtained. A structural model was analyzed with regulation attributes related to six intermediate variables that are established risk or protective factors for adolescent substance use (e.g., academic involvement, stressful life events). Criterion variables were externalizing and internalizing symptomatology and positive well-being. Indirect pathways were found from emotional regulation to symptomatology through academic competence, stressful events, and deviance-prone attitudes and cognitions. Direct effects were also found: from emotional dysregulation to externalizing and internalizing symptomatology; emotional self-control to well-being; and behavioral self-control (inverse) to externalizing symptomatology. Emotional self-control and emotional dysregulation had independent effects and different types of pathways. Adolescents scoring high on emotional dysregulation are at risk for substance dependence because of more externalizing and internalizing symptomatology. Independently, youth with better behavioral and emotional self-control are at lower risk. This occurs partly through relations of regulation constructs to environmental variables that affect levels of symptomatology (e.g., stressful events, poor academic performance). Effects of emotion regulation were found at an early age, before the typical onset of substance disorder. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

Dynamic knee valgus and internal femoral rotation are proposed to be contributory risk factors for patellofemoral pain and anterior cruciate ligament injuries. Multimodal interventions including hip abductor strengthening or functional motor control programmes have a positive impact of pain, however their effect on knee kinematics and muscle strength is less clear. The aim of this study was to examine the effect of isolated hip abductor strengthening and a functional motor control exercise on knee kinematics and hip abductor strength. This prospective, randomised, repeated measures design included 29 asymptomatic volunteers presenting with increase knee valgus and femoral internal rotation. Participants completed either isolated hip abductor strengthening or a functional motor control exercise for 5 weeks. Knee kinematics were measured using inertial sensors during 2 functional activities and hip abductor strength measured using a load cell during isometric hip abduction. There were no significant differences in dynamic knee valgus and internal rotation following the isolated hip abductor or functional motor control intervention, and no significant differences between the groups for knee angles. Despite this, the actual magnitude of reduction in valgus was 10° and 5° for the functional motor control group and strengthening group respectively. The actual magnitude of reduction in internal rotation was 9° and 18° for the functional motor control group and strengthening group respectively. Therefore there was a tendency towards clinically significant improvements in knee kinematics in both exercise groups. A statistically significant improvement in hip abductor strength was evident for the functional motor control group (27% increase; p = 0.008) and strengthening group (35% increase; p = 0.009) with no significant difference between the groups being identified (p = 0.475). Isolated hip strengthening and functional motor control exercises resulted in non-statistically significant changes in knee kinematics, however there was a clear trend towards clinically meaningful reductions in valgus and internal rotation. Both groups demonstrated similar significant gains in hip abductor strength suggesting either approach could be used to strengthen the hip abductors.

This in vitro study compared the tooth color and the ultrastructure of internal dental tissues before and after internal bleaching. Sodium perborate was placed in the pulp chamber of endodontically treated molars and sealed with intermediate restorative material. The test samples were stored in a physiologic solution, and the bleaching agent was replaced every 7 days. A control group was used. After 1 month, the colors of the test and control samples were measured with a colorimeter, and the internal surfaces were observed under field emission scanning electron microscopy (FESEM). Statistically significant differences were found between the test and control sample colors. The FESEM ultrastructure analysis of the internal enamel and dentin surfaces did not show any changes after the internal bleaching. The results of the present study show that sodium perborate is effective in bleaching nonvital teeth and does not produce ultrastructural changes in the dental tissues.

This is the third of three papers that review international policies to control spending on drugs and to improve the efficiency of drug use. This paper reviews policies regulating the supply of drugs, particularly licensing and reimbursement controls, price and profit regulation. Price and profit controls contain few incentives for improving cost effective use of drugs, and focus on cost containment and profitability of domestic industry. Carefully monitored economic evaluation could lead to improvements in efficiency and benefits to patients and the health care system. PMID:8664771

The effect of internal teat sealant products (Teatseal and Orbeseal) on intramammary infection, clinical mastitis, and somatic cell counts in lactating dairy cows: a meta-analysis.

Rabiee, A R; Lean, I J

2013-01-01

The objective of this study was to assess the efficacy of internal teat sealant products containing bismuth subnitrate (Teatseal and Orbeseal; Pfizer Animal Health, West Ryde, Australia) when used alone, or in the presence of antibiotic dry cow therapy (ADCT), before or at drying off on the incidence of new intramammary infections (IMI), clinical mastitis, and milk somatic cell count (SCC) during lactation. The literature search identified 18 English-language publications on the use of Teatseal in dairy cattle. A total of 12 studies with 17 subtrials or comparisons including 13 positive control subtrials (internal teat sealant and ADCT vs. ADCT) and 4 negative control subtrials (internal teat sealant vs. untreated) examining IMI were included in the analysis. Internal teat sealants, alone or in the presence of ADCT, reduced the risk of acquiring new IMI after calving by 25% [risk ratio (RR)=0.75; 95% confidence interval (CI): 0.67 to 0.83]. Internal teat sealants reduced the risk of IMI by 73% compared with untreated cows (RR=0.27; 95% CI: 0.13 to 0.55). The results of both meta-analyses of IMI, with positive and negative controls, were heterogeneous [I(2) (a statistic that describes the proportion of total variation in study effect estimates that is due to heterogeneity)=65.4 and 92.1%]. No farm or cow factors studied significantly contributed to the heterogeneity of the results. A total of 16 studies (21 subtrials), including 14 positive control subtrials and 7 negative control subtrials, examining clinical mastitis were included in the analysis. Internal teat sealants alone and in the presence of ADCT reduced the risk of clinical mastitis after calving in lactating cows by 29% (RR=0.71; 95% CI: 0.62 to 0.82), and 48% (RR=0.52; 95% CI: 0.37 to 0.75), respectively. The results of the meta-analysis on clinical mastitis with positive controls were homogeneous (I(2)=33.6%), whereas the results of studies with negative controls were heterogeneous (I(2)=60.4%). No farm or cow factors studied that had sufficient data to evaluate significantly contributed to the heterogeneity of the results. The estimated linear score (LS) of milk SCC after calving in published studies (n=3) and for studies that provided raw data (n=2), was significantly lower for cattle treated with internal teat sealants and ADCT in 3 studies than for cattle treated with internal teat sealants only. The estimated LS of pooled raw data of 3 studies from 32 herds showed that the LS of cows treated with internal teat sealant and ADCT was not significantly different than those treated with ADCT only. This study found that the application of internal teat sealants in the presence of ADCT or the use of internal teat sealants alone at dry off significantly reduced the incidence of IMI and clinical mastitis in lactating dairy cows compared with respective control groups. Further studies are needed to investigate the effect of internal teat sealants on postpartum milk SCC in lactating dairy cows. Copyright © 2013 American Dairy Science Association.

DREISS: Using State-Space Models to Infer the Dynamics of Gene Expression Driven by External and Internal Regulatory Networks.

PubMed

Wang, Daifeng; He, Fei; Maslov, Sergei; Gerstein, Mark

2016-10-01

Gene expression is controlled by the combinatorial effects of regulatory factors from different biological subsystems such as general transcription factors (TFs), cellular growth factors and microRNAs. A subsystem's gene expression may be controlled by its internal regulatory factors, exclusively, or by external subsystems, or by both. It is thus useful to distinguish the degree to which a subsystem is regulated internally or externally-e.g., how non-conserved, species-specific TFs affect the expression of conserved, cross-species genes during evolution. We developed a computational method (DREISS, dreiss.gerteinlab.org) for analyzing the Dynamics of gene expression driven by Regulatory networks, both External and Internal based on State Space models. Given a subsystem, the "state" and "control" in the model refer to its own (internal) and another subsystem's (external) gene expression levels. The state at a given time is determined by the state and control at a previous time. Because typical time-series data do not have enough samples to fully estimate the model's parameters, DREISS uses dimensionality reduction, and identifies canonical temporal expression trajectories (e.g., degradation, growth and oscillation) representing the regulatory effects emanating from various subsystems. To demonstrate capabilities of DREISS, we study the regulatory effects of evolutionarily conserved vs. divergent TFs across distant species. In particular, we applied DREISS to the time-series gene expression datasets of C. elegans and D. melanogaster during their embryonic development. We analyzed the expression dynamics of the conserved, orthologous genes (orthologs), seeing the degree to which these can be accounted for by orthologous (internal) versus species-specific (external) TFs. We found that between two species, the orthologs have matched, internally driven expression patterns but very different externally driven ones. This is particularly true for genes with evolutionarily ancient functions (e.g. the ribosomal proteins), in contrast to those with more recently evolved functions (e.g., cell-cell communication). This suggests that despite striking morphological differences, some fundamental embryonic-developmental processes are still controlled by ancient regulatory systems.

A robust and high-performance queue management controller for large round trip time networks

NASA Astrophysics Data System (ADS)

Khoshnevisan, Ladan; Salmasi, Farzad R.

2016-05-01

Congestion management for transmission control protocol is of utmost importance to prevent packet loss within a network. This necessitates strategies for active queue management. The most applied active queue management strategies have their inherent disadvantages which lead to suboptimal performance and even instability in the case of large round trip time and/or external disturbance. This paper presents an internal model control robust queue management scheme with two degrees of freedom in order to restrict the undesired effects of large and small round trip time and parameter variations in the queue management. Conventional approaches such as proportional integral and random early detection procedures lead to unstable behaviour due to large delay. Moreover, internal model control-Smith scheme suffers from large oscillations due to the large round trip time. On the other hand, other schemes such as internal model control-proportional integral and derivative show excessive sluggish performance for small round trip time values. To overcome these shortcomings, we introduce a system entailing two individual controllers for queue management and disturbance rejection, simultaneously. Simulation results based on Matlab/Simulink and also Network Simulator 2 (NS2) demonstrate the effectiveness of the procedure and verify the analytical approach.

Background Residents and interns are recognized as important clinical teachers and mentors. Resident-as-teacher training programs are known to improve resident attitudes and perceptions toward teaching, as well as their theoretical knowledge, skills, and teaching behavior. The effect of resident-as-teacher programs on learning outcomes of medical students, however, remains unknown. An intervention cohort study was conducted to prospectively investigate the effects of a teacher-training workshop on teaching behavior of participating interns and on the clerkship learning outcomes of instructed fourth-year medical students. Methods The House Officer-as-Teacher Training Workshop was implemented in November 2009 over 1.5 days and attended by all 34 interns from one teaching hospital. Subsequently, between February and August 2010, 124 fourth-year medical students rated the observable teaching behavior of interns during 6-week general surgery clerkships at this intervention hospital as well as at 2 comparable hospitals serving as control sites. Ratings were collected using an anonymous 15-item Intern Clinical Teaching Effectiveness Instrument. Student achievement of clerkship learning outcomes during this period was evaluated using a validated and centralized objective structured clinical examination. Results Medical students completed 101 intern clinical teaching effectiveness instruments. Intern teaching behavior at the intervention hospital was found to be significantly more positive, compared with observed behavior at the control hospitals. Objective structured clinical examination results, however, did not demonstrate any significant intersite differences in student achievement of general surgery clerkship learning outcomes. Conclusions The House Officer-as-Teacher Training Workshop noticeably improved teaching behavior of surgical interns during general surgery clerkships. This improvement did not, however, translate into improved achievement of clerkship learning outcomes by medical students during the study period. PMID:23451304

Attentional focus and performance anxiety: effects on simulated race-driving performance and heart rate variability.

Mullen, Richard; Faull, Andrea; Jones, Eleri S; Kingston, Kieran

2012-01-01

Previous studies have demonstrated that an external focus can enhance motor learning compared to an internal focus. The benefits of adopting an external focus are attributed to the use of less effortful automatic control processes, while an internal focus relies upon more effort-intensive consciously controlled processes. The aim of this study was to compare the effectiveness of a distal external focus with an internal focus in the acquisition of a simulated driving task and subsequent performance in a competitive condition designed to increase state anxiety. To provide further evidence for the automatic nature of externally controlled movements, the study included heart rate variability (HRV) as an index of mental effort. Sixteen participants completed eight blocks of four laps in either a distal external or internal focus condition, followed by two blocks of four laps in the competitive condition. During acquisition, the performance of both groups improved; however, the distal external focus group outperformed the internal focus group. The poorer performance of the internal focus group was accompanied by a larger reduction in HRV, indicating a greater investment of mental effort. In the competition condition, state anxiety increased, and for both groups, performance improved as a function of the increased anxiety. Increased heart rate and self-reported mental effort accompanied the performance improvement. The distal external focus group also outperformed the internal focus group across both neutral and competitive conditions and this more effective performance was again associated with lower levels of HRV. Overall, the results offer support for the suggestion that an external focus promotes a more automatic mode of functioning. In the competitive condition, both foci enhanced performance and while the improved performance may have been achieved at the expense of greater compensatory mental effort, this was not reflected in HRV scores.

This study was done to develop a internalized stigma reducing program based on cognitive-behavioral therapy and appropriate for patients with schizophrenia and to evaluate its effectiveness. The study design was a mixed method research. Qualitative study, 13 patients with schizophrenia who had experience in overcoming stigma were purposively chosen for interviews and data were analyzed using Giorgi method. Quantitative study, 64 patients with schizophrenia (experimental group=32, control group=32) were recruited. The cognitive-behavioral therapy-based program for reducing internalized stigma in patients with schizophrenia was provided for 8 weeks (12 sessions). Data were collected from June. 20, 2013 to Feb. 14, 2014. Quantitative data were analyzed using χ²-test, t-test, repeated measures ANOVA with the SPSS program. Qualitative results, from the experience of coping with stigma in patients with schizophrenia seventeen themes and five themes-clusters were drawn up. Quantitative results showed that internalized stigma, self-esteem, mental health recovery and quality of life were significantly better in the experimental group compared to the control group. Study findings indicate that this program for reducing internalized stigma in patients with schizophrenia is effective and can be recommended as a rehabilitation program intervention to help patients with schizophrenia to cope with internalized stigma.

Unification theory of optimal life histories and linear demographic models in internal stochasticity.

2014-01-01

Life history of organisms is exposed to uncertainty generated by internal and external stochasticities. Internal stochasticity is generated by the randomness in each individual life history, such as randomness in food intake, genetic character and size growth rate, whereas external stochasticity is due to the environment. For instance, it is known that the external stochasticity tends to affect population growth rate negatively. It has been shown in a recent theoretical study using path-integral formulation in structured linear demographic models that internal stochasticity can affect population growth rate positively or negatively. However, internal stochasticity has not been the main subject of researches. Taking account of effect of internal stochasticity on the population growth rate, the fittest organism has the optimal control of life history affected by the stochasticity in the habitat. The study of this control is known as the optimal life schedule problems. In order to analyze the optimal control under internal stochasticity, we need to make use of "Stochastic Control Theory" in the optimal life schedule problem. There is, however, no such kind of theory unifying optimal life history and internal stochasticity. This study focuses on an extension of optimal life schedule problems to unify control theory of internal stochasticity into linear demographic models. First, we show the relationship between the general age-states linear demographic models and the stochastic control theory via several mathematical formulations, such as path-integral, integral equation, and transition matrix. Secondly, we apply our theory to a two-resource utilization model for two different breeding systems: semelparity and iteroparity. Finally, we show that the diversity of resources is important for species in a case. Our study shows that this unification theory can address risk hedges of life history in general age-states linear demographic models.

Evidence that science locus of control orientation can be modified through instruction

NASA Astrophysics Data System (ADS)

Haury, David L.

A desire to foster enduring, positive attitudes toward science teaching among elementary school teachers led to study of self-perceptions. On the basis of evidence for strong links between locus of control orientation and attitudes, an attempt was made to enhance internality through instruction.A quasiexperimental research strategy was employed to compare the effects of two instructional treatments, with pretest measures being used to check the initial equivalence of treatment groups, and analysis of covariance (ANCOVA) being used to test treatment effects. Both treatments incorporated strategies known to have positive effects on attitudes, but the experimental treatment was novel in its emphasis on self-management, goal clarification, and individualized course expectations.There was found by ANCOVA to be a significant (p 0.05) difference in science locus of control (SciLOC) orientation between groups following treatment, with subjects exposed to the experimental treatment exhibiting greater internality. Quantitative comprehension and subject age were employed as covariates of SciLOC orientation, and subject gender was employed as a moderator variable. Though the treatment effect is small, accounting for 3% of the variance in SciLOC orientation, control orientation is shown susceptible to educational intervention. These results encourage attention to teacher attitudes from a rather new perspective, and they raise several interesting research questions regarding instructional methods and the long-term effects of enhancing internality.

To compare clinical effect of T-shaped locking internal fixation and external fixation in treating dorsal Barton's fracture,and investigate selective strategy of internal fixation. From January 2008 to January 2013, 100 patients with dorsal Barton's fracture were randomly divided into two groups. In treatment group, there were 30 males and 20 females with an average age of (33.8±3.6) years old;30 cases were type B, 20 cases were type C;and treated with T-shaped locking internal fixation. In control group, there were 32 male and 18 females with an average age of (32.9±3.4) years old; 29 cases were type B, 21 cases were type C; and treated with external fixation. Volar tilt, ulnar deviation and radial height at 3 months after operation were detected and compared between two groups. Mechara functional evaluation were used to evaluate postoperative clinical effects. Clinical cure time, postoperative complications,joint mobility and function score were recorded and compared between two groups. In treatment group,volar tilt was (11.9±2.7)°, ulnar deviation was (20.8+ 2.9)°,and radial height was (10.9±1.8) mm; while volar tilt was (9.1±1.6)°, ulnar deviation was (17.1±2.9)°, and radial height was (8.1±1.5) mm in control group. Treatment group was better than control group in volar tilt, ulnar deviation and radial height. Clinical cure time in treatment group was(12.0±2.3) weeks, shorter than control group (18.0±4.1) weeks. The incidence of complications in treatment group was lower than control group. According to Mehara functional evaluation,20 cases got excellent results, 25 good, 3 moderate and 2 poor in treatment group; 16 cases got excellent results, 14 good, 10 moderate and 10 poor in control group. Treatment group was better than control group in clinical effects. T-shaped locking internal fixation with postoperative functional exercise for the treatment of dorsal Barton's fracture fits for biomechanics demands,and has advantages of stable fixation,rapid recovery, less complications and good functional recovery, it has better clinical effects.

International covenants establish a role for governments in ensuring the conditions for human health and wellbeing, which has been recognised as a central human right. International trade agreements, conversely, prioritise the rights of corporations over health and human rights. International trade agreements are threatening existing tobacco control policies and restrict the possibility of implementing new controls. This situation is unrecognised by many tobacco control advocates in signatory nations, especially those in developing countries. Recent agreements on eliminating various trade restrictions, including those on tobacco, have expanded far beyond simply international movement of goods to include internal tobacco distribution regulations and intellectual property rules regulating advertising and labelling. Our analysis shows that to the extent trade agreements protect the tobacco industry, in itself a deadly enterprise, they erode human rights principles and contribute to ill health. The tobacco industry has used trade policy to undermine effective barriers to tobacco importation. Trade negotiations provide an unwarranted opportunity for the tobacco industry to assert its interests without public scrutiny. Trade agreements provide the industry with additional tools to obstruct control policies in both developed and developing countries and at every level. The health community should become involved in reversing these trends, and help promote additional measures to protect public health. PMID:16046697

Recombinase polymerase amplification (RPA) is an isothermal nucleic acid amplification technology that provides rapid and robust infectious disease pathogen detection, ideal for point-of-care (POC) diagnostics in disease-prevalent low-resource countries. We have developed and evaluated three duplex RPA assays incorporating competitive internal controls for the detection of leading bacterial meningitis pathogens. Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae singleplex RPA assays were initially developed and evaluated, demonstrating 100% specificity with limits of detection of 4.1, 8.5 and 3.9 genome copies per reaction, respectively. Each assay was further developed into internally controlled duplex RPA assays via the incorporation of internal amplification control templates. Clinical performance of each internally controlled duplex RPA assay was evaluated by testing 64 archived PCR-positive clinical samples. Compared to real-time PCR, all duplex RPA assays demonstrated 100% diagnostic specificity, with diagnostic sensitivities of 100%, 86.3% and 100% for the S. pneumoniae, N. meningitidis and H. influenzae assays, respectively. This study details the first report of internally controlled duplex RPA assays for the detection of bacterial meningitis pathogens: S. pneumoniae, N. meningitidis and H. influenzae. We have successfully demonstrated the clinical diagnostic utility of each duplex RPA assay, introducing effective diagnostic technology for POC bacterial meningitis identification in disease-prevalent developing countries.

The effect of using standardized parent training history-taking on the quality of medical records and communication skills among pediatric interns was determined. Fifth-year interns who were undertaking a pediatric clinical practice rotation were randomized to intervention and control groups. All of the pediatric interns received history-taking training by lecture and bedside teaching. The pediatric interns in the intervention group also received standardized parent history-taking training. The following two outcome measures were used: the scores of medical records, which were written by the pediatric interns after history-taking from real parents of pediatric patients; and the communication assessment tool (CAT) assessed by real parents. The general information, history of present illness (HPI), past medical history, personal history, family history, diagnosis, diagnostic analysis, and differential diagnosis scores in the intervention group were significantly higher than the control group (p < 0.05). Assessment of the CAT indicated that the real parents were more satisfied with the pediatric interns in the intervention group. Standardized parent training history-taking is effective in improving the quality of medical records by pediatric interns. Standardized parent training history-taking is a superior teaching tool for clinical reasoning ability, as well as communication skills in clinical pediatric practice.

Perceived Health Locus of Control, Self-Esteem, and Its Relations to Psychological Well-Being Status in Iranian Students

PubMed Central

Moshki, M; Ashtarian, H

2010-01-01

Background: Health locus of control (HLC) has been associated with a variety of ailments and health outcomes and designed to predict behaviors and cognitive processes relevant to mental and physical health. This study investigated the relationships between perceived health locus of control, self-esteem, and mental health status among Iranian students. Methods: In this analytical study the subjects were recruited from students in Gonabad University of Medical Sciences, Iran, who studied in the first year (N=154). Students completed the questionnaires for assessing demographic, perceived health locus of control, self - esteem and psychological well- being data. Results: The statistical analysis revealed a negative relationship between perceived Internal HLC and self-esteem with psychological well-being. The positive correlation of the perceived Chance HLC with psychological well-being was statistically significant (r= 0.21, P< 0.01) and the positive correlation of the perceived Internal HLC with self-esteem was statistically significant (r= 0.25, P< 0.01). A significantly direct relationship between low perceived Internal HLC, self–esteem and psychological problems was found among these students. Conclusion: The findings will be addressed in relation to their implications for effective mental health education based on health locus of control especially internal and powerful others beliefs associated with self-esteem for students. This will require additional monitoring and uninterrupted trying in order to be effective. PMID:23113040

Linear control of the flywheel inverted pendulum.

PubMed

Olivares, Manuel; Albertos, Pedro

2014-09-01

The flywheel inverted pendulum is an underactuated mechanical system with a nonlinear model but admitting a linear approximation around the unstable equilibrium point in the upper position. Although underactuated systems usually require nonlinear controllers, the easy tuning and understanding of linear controllers make them more attractive for designers and final users. In a recent paper, a simple PID controller was proposed by the authors, leading to an internally unstable controlled plant. To achieve global stability, two options are developed here: first by introducing an internal stabilizing controller and second by replacing the PID controller by an observer-based state feedback control. Simulation and experimental results show the effectiveness of the design. Copyright © 2013 ISA. Published by Elsevier Ltd. All rights reserved.

To evaluate the effects of internal displacement and resettlement within Turkey on the emotional and behavioral profile of children, age 5-18 after controlling for possible confounding and demographic variables. We conducted a national population survey using a self-weighted, equal probability sample. We compared the CBCL, TRF and YSR responses regarding children with (n = 1644) and without (n = 1855) experience of internal displacement. We examined the effects of gender, age, paternal employment, resettlement, urban residence and physical illness. The children and adolescents with internal displacement had significantly higher internalizing, externalizing and total problem scores on the CBCL and YSR, and higher internalizing scores on the TRF. The effect of displacement was related to higher internalizing problems when factors like physical illness, child age, child gender and urban residence were accounted. The overall effect was small explaining only 0.1-1.5% of the total variance by parent reports, and not evident by teacher reports. To our knowledge the present study is the first to examine Turkish children and adolescents with and without experience of internal displacement. The results are consistent with previous immigration studies: child age, gender, presence of physical illness and urban residence were more important predictors of internalization and externalization problem scores irrespective of informant source.

The purpose of the present study was to validate the Mandarin version of the International Prostate Symptom Score (Mand-IPSS) in a Malaysian population. The validity and reliability were studied in patients with lower urinary tract symptoms (LUTS; benign prostatic hyperplasia [BPH] group) and without LUTS (control group). Test-retest methodology was used to assess the reliability while Cronbach alpha was used to assess the internal consistency. Sensitivity to change was used to express the effect size index in the preintervention versus post-intervention score in patients with LUTS who underwent transurethral resection of the prostate. For the control group and BPH group, the internal consistency was excellent and a high degree of internal consistency was observed for all seven items (Cronbach alpha = 0.86-0.98 and 0.90-0.98, respectively). Test-retest correlation coefficients for all items were highly significant. Intraclass correlation coefficient (ICC) was high for the control (ICC = 0.93-0.99) and BPH group (ICC = 0.91-0.99). The sensitivity and specificity showed a high degree of sensitivity and specificity to the effects of treatment. A high degree of significance between baseline and post-treatment scores was observed across all seven items in the BPH group but not in the control group. The Mand-IPSS is a suitable, reliable, valid and sensitive instrument to measure clinical change in the Malaysian population.

Aims To assess blood glucose control and quality of health care provided to non-insulin-treated patients with Type 2 diabetes mellitus in routine clinical practice in Spain. Methods In this observational, retrospective, cross-sectional study, patients were grouped as either having good or suboptimal blood glucose control according to International Diabetes Federation or American Diabetes Association HbA1c goals. Clinical and socio-demographic data and compliance with the main standard level of care recommendations of the International Diabetes Federation were recorded during a routine visit. Correlates of glucose control were analysed by logistic regression. Results Many patients were grouped as having suboptimal control under International Diabetes Federation (61.9%) or American Diabetes Association (45.0%) criteria. The mean number of accomplished International Diabetes Federation recommendations (7.3 out of 11) was higher for endocrinologists (than for internists or primary care physicians), and significantly more patients under their care were in the good glucose control group (than with primary care physicians). More recommendations were associated with blood glucose control using International Diabetes Federation than American Diabetes Association criteria, demanding higher quality of health care for achieving stricter goals. Some recommendations were poorly observed, particularly those concerning patients’ education on diabetes, the prompt prescription of effective treatments and monitoring of complications. Diabetes complications were associated with being in the suboptimal control group. Patients’ education on diabetes and HbA1c monitoring were associated with being in the good control group. Conclusions These results demonstrate the need for improvement in the management of patients with non-insulin-treated Type 2 diabetes in actual clinical practice in Spain. Such improvement would entail a stricter adherence to International Diabetes Federation recommendations. PMID:21294772

Locus of control is one of the most widely studied concepts in the history of personality psychology. In spite of its popularity and its associations with numerous relevant outcomes, the ability of locus of control to predict future behaviors involving parenting effectiveness has been under researched. The few parent locus of control children's outcome studies are characterized by cross-sectional methodologies that focus on mothers. The present study uses a prospective methodology to compare data on mothers' and fathers' locus of control with their child's behavior outcomes from a large scale research project, the Avon Longitudinal Study of Parents and Children (ALSPAC). Based on Rotter's Social Learning Theory published in 1954 and past empirical research, it was predicted and found that parent internality was associated with more positive child outcomes than parent externality. More specifically, when both parents were internal, their children had more positive outcomes in sleeping, eating, and tantrum behavior as compared to any other parent locus of control combination. However external parents had a less restrictive attitude which appeared to have a more beneficial effect on picky eating. Results confirmed how important parent locus of control is in the lives of children. Based on the findings, researchers are urged to develop interventions to change advice to parents and promote more internal locus of control among parents. PMID:28446887

The recurrence rate after primary anterior shoulder dislocation is high, especially in young, active individuals. Recent studies have suggested external rotation immobilization as a method to reduce the rate of recurrent shoulder dislocation in comparison to traditional sling immobilization. To assess and summarize evidence from randomized controlled trials on the effect of internal rotation versus external rotation immobilization on the rate of recurrence after primary anterior shoulder dislocation. Meta-analysis. PubMed, MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and abstracts from recent proceedings were searched for eligible studies. Two reviewers selected studies for inclusion, assessed methodological quality, and extracted data. Six randomized controlled trials (632 patients) were included in this review. Demographic and prognostic variables measured at baseline were similar in the pooled groups. The average age was 30.1 years in the pooled external rotation group and 30.3 years in the pooled internal rotation group. Two studies found that external rotation immobilization reduced the rate of recurrence after initial anterior shoulder dislocation compared with conventional internal rotation immobilization, whereas 4 studies failed to find a significant difference between the 2 groups. This meta-analysis suggested no overall significant difference in the rate of recurrence among patients treated with internal rotation versus external rotation immobilization (risk ratio, 0.69; 95% CI, 0.42-1.14; P = .15). There was no significant difference in the rate of compliance between internal and external rotation immobilization (P = .43). The Western Ontario Shoulder Instability Index scores were pooled across 3 studies, and there was no significant difference between the 2 groups (P = .54). Immobilization in external rotation is not significantly more effective in reducing the recurrence rate after primary anterior shoulder dislocation than immobilization in internal rotation. Additionally, this review suggests that there is minimal difference in patients' perceptions of their health-related quality of life after immobilization in internal versus external rotation. © 2015 The Author(s).

To compare the effect of An's Shaobei Injection ([symbols; see text]) with Xiaozhiling Injection ([symbols; see text]) in patients with internal hemorrhoids of grade I-III. This cohort study included 1,520 internal hemorrhoids patients with grade I-III who were scheduled for liquid injection treatment from July 2003 to July 2009. The cohort included patients who underwent either An's Shaobei Injection treatment (the treatment group, 760 cases) or Xiaozhiling Injection treatment (the control group, 760 cases). All patients were followed up regularly for 3 years; the observing indices included anal function recovery and clinical response after operation. Among the 1,520 patients, 1,508 (99.2%) completed the 3-year follow-up. The efficacy rate was 97.5% in the treatment group, significantly higher than the control group (91.8%, P<0.01). The recurrence rate in the treatment group was 0.5%, significantly lower than that of the control group (1.3%, P<0.01). In addition, perianal callosity occurred in 8 cases (1.1%) and anorectal stricture in 26 cases (3.5%) after operation in the control group. There was no perianal callosity and anorectal stricture in the treatment group. The treatment with An's Shaobei Injection demonstrated superior clinical effect to Xiaozhiling Injection with fewer adverse effects.

An Internal Data Non-hiding Type Real-time Kernel and its Application to the Mechatronics Controller

NASA Astrophysics Data System (ADS)

Yoshida, Toshio

For the mechatronics equipment controller that controls robots and machine tools, high-speed motion control processing is essential. The software system of the controller like other embedded systems is composed of three layers software such as real-time kernel layer, middleware layer, and application software layer on the dedicated hardware. The application layer in the top layer is composed of many numbers of tasks, and application function of the system is realized by the cooperation between these tasks. In this paper we propose an internal data non-hiding type real-time kernel in which customizing the task control is possible only by change in the program code of the task side without any changes in the program code of real-time kernel. It is necessary to reduce the overhead caused by the real-time kernel task control for the speed-up of the motion control of the mechatronics equipment. For this, customizing the task control function is needed. We developed internal data non-cryptic type real-time kernel ZRK to evaluate this method, and applied to the control of the multi system automatic lathe. The effect of the speed-up of the task cooperation processing was able to be confirmed by combined task control processing on the task side program code using an internal data non-hiding type real-time kernel ZRK.

Effects of complex internal structures on rheology of multiple emulsions particles in 2D from a boundary integral method.

PubMed

Wang, Jingtao; Liu, Jinxia; Han, Junjie; Guan, Jing

2013-02-08

A boundary integral method is developed to investigate the effects of inner droplets and asymmetry of internal structures on rheology of two-dimensional multiple emulsion particles with arbitrary numbers of layers and droplets within each layer. Under a modest extensional flow, the number increment of layers and inner droplets, and the collision among inner droplets subject the particle to stronger shears. In addition, the coalescence or release of inner droplets changes the internal structure of the multiple emulsion particles. Since the rheology of such particles is sensitive to internal structures and their change, modeling them as the core-shell particles to obtain the viscosity equation of a single particle should be modified by introducing the time-dependable volume fraction Φ(t) of the core instead of the fixed Φ. An asymmetric internal structure induces an oriented contact and merging of the outer and inner interface. The start time of the interface merging is controlled by adjusting the viscosity ratio and enhancing the asymmetry, which is promising in the controlled release of inner droplets through hydrodynamics for targeted drug delivery.

2018-06-01

A large pool of evidence supports the beneficial effect of an external focus of attention on motor skill performance in adults. In children, this effect has been studied less and results are inconclusive. Importantly, individual differences are often not taken into account. We investigated the role of working memory, conscious motor control, and task-specific focus preferences on performance with an internal and external focus of attention in children. Twenty-five children practiced a golf putting task in both an internal focus condition and external focus condition. Performance was defined as the average distance toward the hole in 3 blocks of 10 trials. Task-specific focus preference was determined by asking how much effort it took to apply the instruction in each condition. In addition, working memory capacity and conscious motor control were assessed. Children improved performance in both the internal focus condition and external focus condition (ŋ p 2  = .47), with no difference between conditions (ŋ p 2  = .01). Task-specific focus preference was the only factor moderately related to the difference between performance with an internal focus and performance with an external focus (r = .56), indicating better performance for the preferred instruction in Block 3. Children can benefit from instruction with both an internal and external focus of attention to improve short-term motor performance. Individual, task-specific focus preference influenced the effect of the instructions, with children performing better with their preferred focus. The results highlight that individual differences are a key factor in the effectiveness in children's motor performance. The precise mechanisms underpinning this effect warrant further research.

Moderators and mediators of the effects of interparental conflict on children's adjustment.

PubMed

Kerig, P K

1998-06-01

Moderational and mediational models of the relationships among appraisals, interparental conflict, and children's adjustment were tested in a sample of 174 families with a school-age child. Parents rated children's exposure to interparental conflict and internalizing, externalizing, and total behavior problems. Children completed questionnaires regarding their appraisals of their parents' conflicts, including frequency and intensity, perceived threat, control, and self-blame, as well as measures of anxiety and depression. Results overall demonstrated more consistent support for the moderational than mediational hypotheses. Appraisals of conflict properties, threat, self-blame, and perceived control moderated the effects of interparental conflict on externalizing, total problems, and anxiety in boys. Conflict properties, threat, self-blame, perceived control, and self-calming acted as moderators of internalizing in girls.

We believe that there is significant educational deficit amongst interns regarding up-to-date formal knowledge and skills on healthcare-associated infections (HAIs) which might compromise patient safety. This urgently requires curriculum innovations to ensure their formal training on HAIs prevention and control. Education of interns to improve their knowledge and skills toward HAIs prevention and control. This pilot study was conducted in interns using a multimodal approach consisting of a combination of videos, PowerPoint presentation, and hands-on demonstration to provide applied and practical teaching on prevention and control of HAIs. Pre- and post-test assessment of knowledge, attitude, and skills was carried out by multiple choice questions, 5-point Likert scale, and Objective Structured Practical Examination respectively. Paired t-test. A statistically significant improvement in the overall score rates between pre- and post-test of intern's was seen, suggesting that educational programs have a positive effect. Intern's felt benefitted from interventions focused on HAIs prevention and control and hoped that such sessions are integrated in the regular undergraduate curriculum. A majority of the students felt that their learning style assessment matched well with their own perception of learning preference. Assessment drives learning; hence strengthening the contribution of health-care workers to HAIs prevention programs should include measures that enhance knowledge, improve skills and develop appropriate attitudes, resulting in safety and quality of patient care.

To assess the efficacy and safety of hyaluronate sodium (HS) for internal derangement of temporomandibular joint by means of systematic review on relevant randomized controlled trials. After identifing the study question of the efficacy and safety of HS for internal derangement of temporomandibular joint, Medline, Cochrane Controlled Trials Register, EMBASE, OPEN SIGLE and CBM were searched electronically till October 3rd 2010. Hand-searching covering 19 dental journals in Chinese were also performed. Risk of bias assessment, with Cochrane Collaboration's tool, and data extraction of included studies were conducted by two reviewers in duplicate. Meta analysis was done with Revman 5.0.23 and the quality of evidence was evaluated by GRADE. 10 randomized controlled trials met the eligibility criteria and were included. All these studies had unclear risk of bias. When compared with negative control, HS showed a significant advantage on maximal mouth opening in short and long-term (P < 0.05), and clinical overall assessment in short-term (P < 0.05), but its effect on pain control and long-term effect on clinical overall assessment had no extra benefit (P > 0.05). Additionally, when compared with glucocorticoids, the participants who received HS injection would get a better clinical overall assessment in short-term and less adverse drug reactions (P < 0.05), but presented a similar temporomandibular joint pain relief and maximal mouth opening (P > 0.05). To a certain extent, HS had good efficacy and better safety than controls when treating internal derangement of temporomandibular joint. However, as the quality of some included studies were limited, more randomized controlled trials are needed to reinforce the conclusion.

To prepare the French Accreditation Committee (COFRAC) visit for initial certification of our medical laboratory, our direction evaluated its quality management system (QMS) and all its technical activities. This evaluation was performed owing an internal audit. This audit was outsourced. Auditors had an expertise in audit, a whole knowledge of biological standards and were independent. Several nonconformities were identified at that time, including a lack of control of several steps of the internal audit process. Hence, necessary corrective actions were taken in order to meet the requirements of standards, in particular, the formalization of all stages, from the audit program, to the implementation, review and follow-up of the corrective actions taken, and also the implementation of the resources needed to carry out audits in a pre-established timing. To ensure an optimum control of each step, the main concepts of risk management were applied: process approach, root cause analysis, effects and criticality analysis (FMECA). After a critical analysis of our practices, this methodology allowed us to define our "internal audit" process, then to formalize it and to follow it up, with a whole documentary system.

Background Recognition can be normalized in schizophrenia by providing patients with semantic organizational strategies through a levels-of-processing (LOP) framework. However, patients may rely primarily on familiarity effects, making recognition less sensitive than source monitoring to the strength of the episodic memory trace. The current study investigates whether providing semantic organizational strategies can also normalize patients’ internal source-monitoring performance. Method Sixteen clinically stable medicated patients with schizophrenia and 15 demographically matched healthy controls were asked to identify the source of remembered words following an LOP-encoding paradigm in which they alternated between processing words on a ‘shallow’ perceptual versus a ‘deep’ semantic level. A multinomial analysis provided orthogonal measures of item recognition and source discrimination, and bootstrapping generated variance to allow for parametric analyses. LOP and group effects were tested by contrasting recognition and source-monitoring parameters for words that had been encoded during deep versus shallow processing conditions. Results As in a previous study there were no group differences in LOP effects on recognition performance, with patients and controls benefiting equally from deep versus shallow processing. Although there were no group differences in internal source monitoring, only controls had significantly better performance for words processed during the deep encoding condition. Patient performance did not correlate with clinical symptoms or medication dose. Conclusions Providing a deep processing semantic encoding strategy significantly improved patients’ recognition performance only. The lack of a significant LOP effect on internal source monitoring in patients may reffect subtle problems in the relational binding of semantic information that are independent of strategic memory processes.

The lack of a significant LOP effect on internal source monitoring in patients may reflect subtle problems in the relational binding of semantic information that are independent of strategic memory processes.

The effect of the Convention on International Trade in Endangered Species on scientific collections.

The Convention on International Trade in Endangered Species (CITES) was conceived in the spirit of cooperation, with the aim of ensuring that the international trade in wild animals and plants, including all parts and derivatives, did not threaten their survival. However, concerns have been raised by scientists that CITES hinders the cross-border movement of scientific specimens. To our knowledge, no empirical analysis has been undertaken to demonstrate the existence of this effect. We test for a CITES effect on the collection record of orchids from Brazil and Costa Rica using the collection records of bromeliads, which are not covered by CITES, as a control. Highly significant effects are found in both countries.

Load balancing and closed chain multiple arm control

The authors give the general dynamical equations for several rigid link manipulators rigidly grasping a commonly held rigid object. It is shown that the number of arm-configuration degrees of freedom lost due to imposing the closed-loop kinematic constraints is the same as the number of degrees of freedom gained for controlling the internal forces of the closed-chain system. This number is equal to the dimension of the kernel of the Jacobian operator which transforms contact forces to the net forces acting on the held object, and it is shown that this kernel can be identified with the subspace of controllable internal forces of the closed-chain system. Control of these forces makes it possible to regulate the grasping forces imparted to the held object or to control the load taken by each arm. It is shown that the internal forces can be influenced without affecting the control of the configuration degrees of freedom. Control laws of the feedback linearization type are shown to be useful for controlling the location and attitude of a frame fixed with respect to the held object, while simultaneously controlling the internal forces of the closed-chain system. Force feedback can be used to linearize and control the system even when the held object has unknown mass properties. If saturation effects are ignored, an unconstrained quadratic optimization can be performed to distribute the load optimally among the joint actuators.

DREISS: Using State-Space Models to Infer the Dynamics of Gene Expression Driven by External and Internal Regulatory Networks

PubMed Central

Gerstein, Mark

2016-01-01

Gene expression is controlled by the combinatorial effects of regulatory factors from different biological subsystems such as general transcription factors (TFs), cellular growth factors and microRNAs. A subsystem’s gene expression may be controlled by its internal regulatory factors, exclusively, or by external subsystems, or by both. It is thus useful to distinguish the degree to which a subsystem is regulated internally or externally–e.g., how non-conserved, species-specific TFs affect the expression of conserved, cross-species genes during evolution. We developed a computational method (DREISS, dreiss.gerteinlab.org) for analyzing the Dynamics of gene expression driven by Regulatory networks, both External and Internal based on State Space models. Given a subsystem, the “state” and “control” in the model refer to its own (internal) and another subsystem’s (external) gene expression levels. The state at a given time is determined by the state and control at a previous time. Because typical time-series data do not have enough samples to fully estimate the model’s parameters, DREISS uses dimensionality reduction, and identifies canonical temporal expression trajectories (e.g., degradation, growth and oscillation) representing the regulatory effects emanating from various subsystems. To demonstrate capabilities of DREISS, we study the regulatory effects of evolutionarily conserved vs. divergent TFs across distant species. In particular, we applied DREISS to the time-series gene expression datasets of C. elegans and D. melanogaster during their embryonic development. We analyzed the expression dynamics of the conserved, orthologous genes (orthologs), seeing the degree to which these can be accounted for by orthologous (internal) versus species-specific (external) TFs. We found that between two species, the orthologs have matched, internally driven expression patterns but very different externally driven ones. This is particularly true for genes with evolutionarily ancient functions (e.g. the ribosomal proteins), in contrast to those with more recently evolved functions (e.g., cell-cell communication). This suggests that despite striking morphological differences, some fundamental embryonic-developmental processes are still controlled by ancient regulatory systems. PMID:27760135

Self-esteem and behavioral consequences, which are due to external or internal locus of control, are effective on academic achievement of students. The aim of this study was to determine the prediction of locus of control and self-esteem in academic achievement among the students. This cross-sectional study was conducted on 300 college students in Kermanshah University of Medical Sciences in 2014. Data collection tools were in three sections: demographic, Rotter internal-external locus of control scale and Coopersmith self-esteem inventory. Data were analyzed using the SPSS software version 21. Results showed that 29.8% and 76.2% of the participants had internal locus of control, and high self-esteem, respectively. There was a significant correlation between self-esteem, locus of control and academic achievement of the students. Self-esteem accounted for 39.5% of the variation in academic achievement. It seems that interventions to increase self-esteem among student can help improve academic achievement among them.

Acculturative stress is a common experience for international students and is associated with psychological and physical problems. In a previous study, the authors reported that two stress reduction interventions—expressive writing (EW) and assertiveness training (AT)—had limited overall benefits among international students at an American University. The current analyses of data from that study investigated whether individual differences moderated the effects of EW and AT. Results indicate that greater acculturative stress at baseline predicted greater improvement from both interventions, compared with control. Women benefited more from AT than EW, except that EW improved women’s physical symptoms. Men benefited more from EW than AT. Students with limited emotional awareness and expression tended to benefit from both interventions, relative to control. Finally, nation of origin cultural differences generally did not predict outcomes. It is concluded that the benefits of EW and AT and can be enhanced by targeting these interventions to specific subgroups of international students. PMID:21660220

Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

This study used a quasi-experimental design with a pretest-posttest control group and follow-up to determine the efficacy of adherence therapy in patients with schizophrenia in Turkey. The sample of this study consisted of patients with schizophrenia (n=30). The Questionnaire Form, Medication Adherence Rating Scale, Internalized Stigma of Mental Illness Scale, and Beck Cognitive Insight Scale were used. The patients were assigned to experimental (n=15) and control (n=15) groups using the randomization method. The experimental group received adherence therapy in eight sessions. When the scores of the patients in the experimental and control groups were compared at the pretest, posttest, and 3- and 6-months follow ups, a significant difference was only found in the Medication Adherence Rating Scale posttest scores. Adherence therapy is effective in improving adherence to treatment but is not effective with regard to insight and internalized stigma in patients with schizophrenia. Copyright © 2015 Elsevier Inc.

Cognitive control is an important mental ability that is examined using a multitude of cognitive control tasks and effects. The present paper presents the first steps in the elaboration of a functional approach, which aims to uncover the communalities and differences between different cognitive control tasks and their effects. Based on the idea that responses in cognitive control tasks qualify as operant behaviour, we propose to reinterpret cognitive control tasks in terms of operant contingencies and cognitive control effects as instances of moderated stimulus control. We illustrate how our approach can be used to uncover communalities between topographically different cognitive control tasks and can lead to novel questions about the processes underlying cognitive control. © 2015 International Union of Psychological Science.

We estimated the cost-effectiveness of hemiarthroplasty compared to internal fixation for elderly patients with displaced femoral neck fractures. Over 2 years, patients treated with hemiarthroplasty gained more quality-adjusted life years than patients treated with internal fixation. In addition, costs for hemiarthroplasty were lower. Hemiarthroplasty was thus cost effective. Estimating the cost utility of hemiarthroplasty compared to internal fixation in the treatment of displaced femoral neck fractures in the elderly. A cost-utility analysis (CUA) was conducted alongside a clinical randomized controlled trial at a university hospital in Norway; 166 patients, 124 (75%) women with a mean age of 82 years were randomized to either internal fixation (n = 86) or hemiarthroplasty (n = 80). Patients were followed up at 4, 12, and 24 months. Health-related quality of life was assessed with the EQ-5D, and in combination with time used to calculate patients' quality-adjusted life years (QALYs). Resource use was identified, quantified, and valued for direct and indirect hospital costs and for societal costs. Results were expressed in incremental cost-effectiveness ratios. Over the 2-year period, patients treated with hemiarthroplasty gained 0.15-0.20 more QALYs than patients treated with internal fixation. For the hemiarthroplasty group, the direct hospital costs, total hospital costs, and total costs were non-significantly less costly compared with the internal fixation group, with an incremental cost of €2,731 (p = 0.81), €2,474 (p = 0.80), and €14,160 (p = 0.07), respectively. Thus, hemiarthroplasty was the dominant treatment. Sensitivity analyses by bootstrapping supported these findings. Hemiarthroplasty was a cost-effective treatment. Trial registration, NCT00464230.

Effects of internal gain assumptions in building energy calculations

Christensen, C.; Perkins, R.

1981-01-01

The utilization of direct solar gains in buildings can be affected by operating profiles, such as schedules for internal gains, thermostat controls, and ventilation rates. Building energy analysis methods use various assumptions about these profiles. The effects of typical internal gain assumptions in energy calculations are described. Heating and cooling loads from simulations using the DOE 2.1 computer code are compared for various internal gain inputs: typical hourly profiles, constant average profiles, and zero gain profiles. Prototype single-family-detached and multifamily-attached residential units are studied with various levels of insulation and infiltration. Small detached commercial buildings and attached zones in large commercial buildings are studied with various levels of internal gains. The results indicate that calculations of annual heating and cooling loads are sensitive to internal gains, but in most cases are relatively insensitive to hourly variations in internal gains.

The components overheating inside an object, such as inside an electric control cabinet, a moving object, and a running machine, can easily lead to equipment failure or fire accident. The infrared remote sensing method is used to inspect the surface temperature of object to identify the overheating components inside the object in recent years. It has important practical application of using infrared thermal imaging surface temperature measurement to identify the internal overheating elements inside an electric control cabinet. In this paper, through the establishment of test bench of electric control cabinet, the experimental study was conducted on the inverse identification technology of internal overheating components inside an electric control cabinet using infrared thermal imaging. The heat transfer model of electric control cabinet was built, and the temperature distribution of electric control cabinet with internal overheating element is simulated using the finite volume method (FVM). The outer surface temperature of electric control cabinet was measured using the infrared thermal imager. Combining the computer image processing technology and infrared temperature measurement, the surface temperature distribution of electric control cabinet was extracted, and using the identification algorithm of inverse heat transfer problem (IHTP) the position and temperature of internal overheating element were identified. The results obtained show that for single element overheating inside the electric control cabinet the identifying errors of the temperature and position were 2.11% and 5.32%. For multiple elements overheating inside the electric control cabinet the identifying errors of the temperature and positions were 3.28% and 15.63%. The feasibility and effectiveness of the method of IHTP and the correctness of identification algorithm of FVM were validated.

Aims To evaluate the effects of internal displacement and resettlement within Turkey on the emotional and behavioral profile of children, age 5–18 after controlling for possible confounding and demographic variables. Method We conducted a national population survey using a self-weighted, equal probability sample. We compared the CBCL, TRF and YSR responses regarding children with (n = 1644) and without (n = 1855) experience of internal displacement. We examined the effects of gender, age, paternal employment, resettlement, urban residence and physical illness. Results The children and adolescents with internal displacement had significantly higher internalizing, externalizing and total problem scores on the CBCL and YSR, and higher internalizing scores on the TRF. The effect of displacement was related to higher internalizing problems when factors like physical illness, child age, child gender and urban residence were accounted. The overall effect was small explaining only 0.1–1.5% of the total variance by parent reports, and not evident by teacher reports. Discussion To our knowledge the present study is the first to examine Turkish children and adolescents with and without experience of internal displacement. The results are consistent with previous immigration studies: child age, gender, presence of physical illness and urban residence were more important predictors of internalization and externalization problem scores irrespective of informant source.

The internalizing and externalizing problems relating to childhood and adolescent have always been significant. Because there is special considerations in establishing communication with them and hence, the therapeutic methods for these problems must take into account these considerations. As establishing a therapeutic relationship is an important component of effective counseling, it seems that art therapy may help alleviate these problems. The purpose of this study is to determine the effectiveness of art therapy in reducing internalizing and externalizing problems of adolescent girls (14 - 18 years old). This is a semi-experimental study carried out in the form of a pre-test/post-test design with control group. The population of this study includes female students of Gole Laleh School of Art in district 3 of Tehran, Iran, out of which 30 students with internalizing problems and 30 individuals with externalizing problems were selected through targeted sampling. Students were randomly assigned to control and experimental groups. Experimental groups participated in 6 painting sessions designed based on Art therapy theories and previous studies. The material used for diagnosis of the problems in posttest and pretest was an Achenbach self-assessment form. Data were analyzed using a mixed analysis of variance (ANOVA). Our results showed that Art therapy significantly reduced internalizing problems (F = 17.61, P < 0.001); however, its effect in reducing externalizing problems was not significant (F = 3.93, P = 0.06). Art therapy as a practical therapeutic method can be used to improve internalizing problems. To reduce externalizing problems, more sessions may be needed. Thus, future studies are required to insure these findings.

Effects of Internal Border Control on Spread of Pandemic Influenza

We investigated the capacity of internal border control to limit influenza spread in an emergent pandemic in the context of Australia, a country with a low-population density and geopolitical boundaries that may facilitate restrictions. Mathematical models were used to study the time delay between epidemics in 2 population centers when travel restrictions were imposed. The models demonstrated that population size, travel rates, and places where travelers reside can strongly influence delay. The model simulations suggested that moderate delays in geographic spread may be possible with stringent restrictions and a low reproduction number, but results will be sensitive to the reproduction number and timing of restrictions. Model limitations include the absence of further importations and additional control measures. Internal border control may have a role in protecting domestic centers early in a pandemic, when importations are sparse. Our results may be useful for policymakers. PMID:18214176

2003-01-01

Since activating the International Space Station s (IS9 Service Module in November 2000, archival air quality samples have shown highly variable concentrations of octafluoropropane in the cabin. This variability has been directly linked to leakage from air conditioning systems on board the Service Module, Zvezda. While octafluoro- propane is not highly toxic, it presents a significant chal- lenge to the trace contaminant control systems. A discussion of octafluoropropane concentration dynamics is presented and the ability of on board trace contami- nant control systems to effectively remove octafluoropro- pane from the cabin atmosphere is assessed. Consideration is given to operational and logistics issues that may arise from octafluoropropane and other halo- carbon challenges to the contamination control systems as well as the potential for effecting cabin air quality.

The impact of thin idealized media images on body satisfaction: does body appreciation protect women from negative effects?

PubMed

Halliwell, Emma

2013-09-01

This article examines whether positive body image can protect women from negative media exposure effects. University women (N=112) were randomly allocated to view advertisements featuring ultra-thin models or control images. Women who reported high levels of body appreciation did not report negative media exposure effects. Furthermore, the protective role of body appreciation was also evident among women known to be vulnerable to media exposure. Women high on thin-ideal internalization and low on body appreciation reported appearance-discrepancies that were more salient and larger when they viewed models compared to the control group. However, women high on thin-ideal internalization and also high on body appreciation rated appearance-discrepancies as less important and no difference in size than the control group. The results support the notion that positive body image protects women from negative environmental appearance messages and suggests that promoting positive body image may be an effective intervention strategy.

Thermal expansion properties of solids are of fundamental interest and control of thermal expansion is important for practical applications but can be difficult to achieve. Many framework-type materials show negative thermal expansion when internal cages are empty but positive thermal expansion when additional atoms or molecules fill internal voids present. Here we show that redox intercalation offers an effective method to control thermal expansion from positive to zero to negative by insertion of Li ions into the simple negative thermal expansion framework material ScF3, doped with 10% Fe to enable reduction. The small concentration of intercalated Li ions has a strong influence through steric hindrance of transverse fluoride ion vibrations, which directly controls the thermal expansion. Redox intercalation of guest ions is thus likely to be a general and effective method for controlling thermal expansion in the many known framework materials with phonon-driven negative thermal expansion.

Evaluation of Low-Earth-Orbit Environmental Effects on International Space Station Thermal Control Materials

NASA Technical Reports Server (NTRS)

Dever, Joyce A.

1998-01-01

Many spacecraft thermal control coatings in low Earth orbit (LEO) can be affected by solar ultraviolet radiation and atomic oxygen. Ultraviolet radiation can darken some polymers and oxides commonly used in thermal control materials. Atomic oxygen can erode polymer materials, but it may reverse the ultraviolet-darkening effect on oxides. Maintaining the desired solar absorptance for thermal control coatings is important to assure the proper operating temperature of the spacecraft. Thermal control coatings to be used on the International Space Station (ISS) were evaluated for their performance after exposure in the NASA Lewis Research Center's Atomic Oxygen-Vacuum Ultraviolet Exposure (AO-VUV) facility. This facility simulated the LEO environments of solar vacuum ultraviolet (VUV) radiation (wavelength range, 115 to 200 nanometers (nm)) and VUV combined with atomic oxygen. Solar absorptance was measured in vacuo to eliminate the "bleaching" effects of ambient oxygen on VUV-induced degradation. The objective of these experiments was to determine solar absorptance increases of various thermal control materials due to exposure to simulated LEO conditions similar to those expected for ISS. Work was done in support of ISS efforts at the requests of Boeing Space and Defense Systems and Lockheed Martin Vought Systems.

Thinking about thinking: Neural mechanisms and effects on memory.

Bonhage, Corinna; Weber, Friederike; Exner, Cornelia; Kanske, Philipp

2016-02-15

It is a well-established finding that memory encoding is impaired if an external secondary task (e.g. tone discrimination) is performed simultaneously. Yet, while studying we are also often engaged in internal secondary tasks such as planning, ruminating, or daydreaming. It remains unclear whether such a secondary internal task has similar effects on memory and what the neural mechanisms underlying such an influence are. We therefore measured participants' blood oxygenation level dependent responses while they learned word-pairs and simultaneously performed different types of secondary tasks (i.e., internal, external, and control). Memory performance decreased in both internal and external secondary tasks compared to the easy control condition. However, while the external task reduced activity in memory-encoding related regions (hippocampus), the internal task increased neural activity in brain regions associated with self-reflection (anterior medial prefrontal cortex), as well as in regions associated with performance monitoring and the perception of salience (anterior insula, dorsal anterior cingulate cortex). Resting-state functional connectivity analyses confirmed that anterior medial prefrontal cortex and anterior insula/dorsal anterior cingulate cortex are part of the default mode network and salience network, respectively. In sum, a secondary internal task impairs memory performance just as a secondary external task, but operates through different neural mechanisms. Copyright © 2015 Elsevier Inc. All rights reserved.

International university students often experience acculturative stress, and culturally appropriate techniques to manage stress are needed. This randomized trial tested the effects of group assertiveness training, private expressive writing, their combination, and a wait-list control on the acculturative stress, affect, and health of 118 international students at an urban, American university. Interventions were conducted at the start of a semester, and assessments were conducted at baseline and the end of the semester. Group assertiveness training was rated positively by students and led to lower negative affect, whereas expressive writing was less well received and led to higher homesickness and fear, but also higher positive affect. The combined intervention had no effects, perhaps because the two components negated each other. It is concluded that group assertiveness training improves emotional adjustment of international students, but expressive writing has mixed effects and needs further development and study.

A control installation is described for the dosing or proportioning of a secondary air quantity for the improvement of combustion in internal combustion engines, or the after-burning of the exhaust gases of internal combustion engines. An auxiliary arrangement is responsive to an emergency signal for effecting the prompt shutting-off of the secondary air. The emergency signal may be initiated in response to a failure in the ignition voltage of the internal combustion engine; an increase in the hydrocarbon content of the exhaust gases; a disparity between the position of the mixture dosing element and the engine rotational speed; the exceedingmore » of a limiting temperature in the exhaust gas manifold; or the exceeding of a limiting temperature in the afterburner.« less

Simple adaptive control system design for a quadrotor with an internal PFC

NASA Astrophysics Data System (ADS)

Mizumoto, Ikuro; Nakamura, Takuto; Kumon, Makoto; Takagi, Taro

2014-12-01

The paper deals with an adaptive control system design problem for a four rotor helicopter or quadrotor. A simple adaptive control design scheme with a parallel feedforward compensator (PFC) in the internal loop of the considered quadrotor will be proposed based on the backstepping strategy. As is well known, the backstepping control strategy is one of the advanced control strategy for nonlinear systems. However, the control algorithm will become complex if the system has higher order relative degrees. We will show that one can skip some design steps of the backstepping method by introducing a PFC in the inner loop of the considered quadrotor, so that the structure of the obtained controller will be simplified and a high gain based adaptive feedback control system will be designed. The effectiveness of the proposed method will be confirmed through numerical simulations.

Results of the International Space Station (ISS) Node 2 Internal Active Thermal Control System (IATCS) gross leakage analysis are presented for evaluating total leakage flowrates and volume discharge caused by a gross leakage event (i.e. open boundary condition). A Systems Improved Numerical Differencing Analyzer and Fluid Integrator (SINDA/FLUINT) thermal hydraulic mathematical model (THMM) representing the Node 2 IATCS was developed to simulate system performance under steady-state nominal conditions as well as the transient flow effects resulting from an open line exposed to ambient. The objective of the analysis was to determine the adequacy of the leak detection software in limiting the quantity of fluid lost during a gross leakage event to within an acceptable level.

This paper presents an online estimation method of cutting error by analyzing of internal sensor readings. The internal sensors of numerical control (NC) machine tool are selected to avoid installation problem. The estimation mathematic model of cutting error was proposed to compute the relative position of cutting point and tool center point (TCP) from internal sensor readings based on cutting theory of gear. In order to verify the effectiveness of the proposed model, it was simulated and experimented in gear generating grinding process. The cutting error of gear was estimated and the factors which induce cutting error were analyzed. The simulation and experiments verify that the proposed approach is an efficient way to estimate the cutting error of work-piece during machining process.

Internalized stigma can lead to pervasive negative effects among people with severe mental illness (SMI). Although prevalence of internalized stigma is high, there is a dearth of interventions and meanwhile a lack of evidence as to their effectiveness. This study aims at unraveling the existence of different therapeutic interventions and the effectiveness internalized stigma reduction in people with SMI via a systematic review and meta-analysis. Five electronic databases were searched. Studies were included if they (1) involved community or hospital based interventions on internalized stigma, (2) included participants who were given a diagnosis of SMI>50%, and (3) were empirical and quantitative in nature. Fourteen articles were selected for extensive review and five for meta-analysis. Nine studies showed significant decrease in internalized stigma and two showed sustainable effects. Meta-analysis showed that there was a small to moderate significant effect in therapeutic interventions (SMD=-0.43; p=0.003). Among the intervention elements, four studies suggested a favorable effect of psychoeducation. Meta-analysis showed that there was small to moderate significant effect (SMD=-0.40; p=0.001). Most internalized stigma reduction programs appear to be effective. This systematic review cannot make any recommendation on which intervention is more effective although psychoeducation seems most promising. More Randomized Controlled Trials (RCT) on particular intervention components using standard outcome measures are recommended in future studies. Copyright © 2016. Published by Elsevier B.V.

An internal control DNA (ICD) with the same primer binding sequences as the target Chlamydia trachomatis DNA was constructed and evaluated in a PCR assay with immunoenzymatic detection. One hundred urine specimens were tested, and 23 were found to contain inhibitors of the PCR, if not subjected to DNA extraction prior to amplification. Coamplification and detection of the ICD appeared to be a useful method for estimating the effects of inhibitors on C. trachomatis DNA amplification. PMID:12624066

Nanoparticle hardness controls the internalization pathway for drug delivery

Li, Ye; Zhang, Xianren; Cao, Dapeng

2015-01-01

Nanoparticle (NP)-based drug delivery systems offer fundamental advantages over current therapeutic agents that commonly display a longer circulation time, lower toxicity, specific targeted release, and greater bioavailability. For successful NP-based drug delivery it is essential that the drug-carrying nanocarriers can be internalized by the target cells and transported to specific sites, and the inefficient internalization of nanocarriers is often one of the major sources for drug resistance. In this work, we use the dissipative particle dynamics simulation to investigate the effect of NP hardness on their internalization efficiency. Three simplified models of NP platforms for drug delivery, including polymeric NP, liposome and solid NP, are designed here to represent increasing nanocarrier hardness. Simulation results indicate that NP hardness controls the internalization pathway for drug delivery. Rigid NPs can enter the cell by a pathway of endocytosis, whereas for soft NPs the endocytosis process can be inhibited or frustrated due to wrapping-induced shape deformation and non-uniform ligand distribution. Instead, soft NPs tend to find one of three penetration pathways to enter the cell membrane via rearranging their hydrophobic and hydrophilic segments. Finally, we show that the interaction between nanocarriers and drug molecules is also essential for effective drug delivery.

Effects of Surfactant Contamination on the Next Generation Gas Trap for the ISS Internal Thermal Control System

2004-01-01

The current dual-membrane gas trap is designed to remove non-condensed gas bubbles from the Internal Thermal Control System (ITCS) coolant on board the International Space Station (ISS). To date it has successfully served its purpose of preventing gas bubbles from causing depriming, overspeed, and shutdown of the ITCS pump. However, contamination in the ITCS coolant has adversely affected the gas venting rate and lifetime of the gas trap, warranting a development effort for a next-generation gas trap. Previous testing has shown that a hydrophobic-only design is capable of performing even better than the current dual-membrane design for both steady-state gas removal and gas slug removal in clean deionized water. This paper presents results of testing to evaluate the effects of surfactant contamination on the steady-state performance of the hydrophobic-only design.

Over the past few decades, the importance of economic research in advancing tobacco control policies has become increasingly clear. Extensive research has demonstrated that increasing tobacco taxes and prices is the single most cost-effective tobacco control measure. The research contained in this supplement adds to this evidence and provides new insights into how smokers respond to tax and price changes using the rich data on purchase behaviours, brand choices, tax avoidance and evasion, and tobacco use collected systematically and consistently across countries and over time by the International Tobacco Control (ITC) Project. The findings from this research will help inform policymakers, public health professionals, advocates, and others seeking to maximise the public health and economic benefits from higher taxes.

A distinguishing characteristic of high performance organizations is a strong internal control structure-controls that ensure patient care, compliance with regulations, internal efficiencies, and financial reporting. It is controls on financial reporting that are receiving a great deal of attention under a new law, the Sarbanes-Oxley Act of 2002. Public companies are now required by law to document controls over financial reporting, in order to fully address exposures and the effectiveness of current controls. Though many healthcare organizations are not directly affected by the law, regulatory agencies could follow suit and require similar compliance. In fact, several states have introduced bills that require nonprofit organizations to adhere to portions of the act. This article provides a guide for organizations desiring to stay ahead of the curve.

Child temperament moderates the impact of parental separation on adolescent mental health: The trails study.

2011-02-01

The potential effect of parental separation during early adolescence on adolescent externalizing and internalizing problems was investigated in a longitudinal sample of adolescents (n = 1274; mean age = 16.27; 52.3% girls). Pre-separation mental health problems were controlled for. Building on a large number of studies that overall showed a small effect of parental separation, it was argued that separation may only or especially have an effect under certain conditions. It was examined whether child temperament (effortful control and fearfulness) moderates the impact of parental separation on specific mental health domains. Hypotheses were derived from a goal-framing theory, with a focus on goals related to satisfying the need for autonomy and the need to belong. Controlling for the overlap between the outcome domains, we found that parental separation led to an increase in externalizing problems but not internalizing problems when interactions with child temperament were ignored. Moreover, child temperament moderated the impact of parental separation, in that it was only related to increased externalizing problems for children low on effortful control, whereas it was only related to increased internalizing problems for children high on fearfulness. The results indicate that person-environment interactions are important for understanding the development of mental health problems and that these interactions can be domain-specific.

Postharvest Exogenous Application of Abscisic Acid Reduces Internal Browning in Pineapple.

PubMed

Zhang, Qin; Liu, Yulong; He, Congcong; Zhu, Shijiang

2015-06-10

Internal browning (IB) is a postharvest physiological disorder causing economic losses in pineapple, but there is no effective control measure. In this study, postharvest application of 380 μM abscisic acid (ABA) reduced IB incidence by 23.4-86.3% and maintained quality in pineapple fruit. ABA reduced phenolic contents and polyphenol oxidase and phenylalanine ammonia lyase activities; increased catalase and peroxidase activities; and decreased O2(·-), H2O2, and malondialdehyde levels. This suggests ABA could control IB through inhibiting phenolics biosynthesis and oxidation and enhancing antioxidant capability. Furthermore, the efficacy of IB control by ABA was not obviously affected by tungstate, ABA biosynthesis inhibitor, nor by diphenylene iodonium, NADPH oxidase inhibitor, nor by lanthanum chloride, calcium channel blocker, suggesting that ABA is sufficient for controlling IB. This process might not involve H2O2 generation, but could involve the Ca(2+) channels activation. These results provide potential for developing effective measures for controlling IB in pineapple.

Generator voltage stabilisation for series-hybrid electric vehicles.

PubMed

Stewart, P; Gladwin, D; Stewart, J; Cowley, R

2008-04-01

This paper presents a controller for use in speed control of an internal combustion engine for series-hybrid electric vehicle applications. Particular reference is made to the stability of the rectified DC link voltage under load disturbance. In the system under consideration, the primary power source is a four-cylinder normally aspirated gasoline internal combustion engine, which is mechanically coupled to a three-phase permanent magnet AC generator. The generated AC voltage is subsequently rectified to supply a lead-acid battery, and permanent magnet traction motors via three-phase full bridge power electronic inverters. Two complementary performance objectives exist. Firstly to maintain the internal combustion engine at its optimal operating point, and secondly to supply a stable 42 V supply to the traction drive inverters. Achievement of these goals minimises the transient energy storage requirements at the DC link, with a consequent reduction in both weight and cost. These objectives imply constant velocity operation of the internal combustion engine under external load disturbances and changes in both operating conditions and vehicle speed set-points. An electronically operated throttle allows closed loop engine velocity control. System time delays and nonlinearities render closed loop control design extremely problematic. A model-based controller is designed and shown to be effective in controlling the DC link voltage, resulting in the well-conditioned operation of the hybrid vehicle.

A comparative study of RNA and DNA as internal gene expression controls early in the developmental cycle of Chlamydia pneumoniae.

Many microbial pathogens invade and proliferate within host cells and the molecular mechanism underlying this behavior is currently being revealed for several bacterial species. Testing clinically relevant antibacterial compounds and elucidating their effects on gene expression requires adequate controls, especially when studying genetically intractable organisms such as Chlamydia spp., for which various gene fusions cannot be constructed. Until now, relative mRNA levels in Chlamydia have been measured using different internal gene expression controls, including 16S rRNA, mRNAs, and DNA. Here, we compared the advantages and disadvantages of various internal expression controls during the early phase of Chlamydia pneumoniae development. The relative abundance of target mRNAs varied using the different internal control RNAs. This was partly due to variation in the transcript stability of the RNA species. Also, seven out of nine of the analyzed RNAs increased fivefold or more between 2 and 14 h postinfection, while the amount of DNA and number of cells remained essentially unaltered. Our results suggest that RNA should not be used as a gene expression control during the early phase of Chlamydia development, and that intrinsic bacterial DNA is preferable for that purpose because it is stable, abundant, and its relative amount is generally correlated with bacterial numbers.

Several organizations have advocated for comprehensive redesign of graduate medical training, but the effect that residency redesign will have on measures of patient satisfaction, resident and intern (trainee) satisfaction, and patient care is unknown. We designed an experimental inpatient-medicine service with reduced resident workload comprising two teams, with each team consisting of two attending physicians, two residents, and three interns. Attending physicians, selected for their teaching prowess, supervised the teams throughout the workday and during bedside team-teaching rounds. This experimental model was compared with a control model comprising two teams, with each consisting of one resident and two interns, plus multiple supervising attending physicians who volunteered to participate. Patients were alternately assigned to the experimental teams and the control teams, subject to limits on the number of patients interns are allowed to admit. Over a 12-month period, 1892 patients were assigned to the experimental teams and 2096 to the control teams; the average census per intern was 3.5 and 6.6 patients, respectively. Overall satisfaction was significantly higher among trainees on the experimental teams than among those on the control teams (78% and 55%, respectively; P=0.002). As compared with the control teams, the experimental teams were not associated with a higher average length of patient stay or readmission rate; adherence to standards for quality of inpatient care was similar in both groups of teams. Interns on the experimental teams spent more time in learning and teaching activities than did interns on the control teams (learning: 20% of total time vs. 10%, P=0.01; teaching: 8% of total time vs. 2%, P=0.006). As compared with a traditional inpatient care model, an experimental model characterized by reduced trainee workload and increased participation of attending physicians was associated with higher trainee satisfaction and increased time for educational activities. 2010 Massachusetts Medical Society

To investigate general and program-specific factors hypothesized to moderate the effects of two eating disorder prevention programs. High-risk adolescent girls (N = 481; M age = 17) were randomized to a dissonance-based thin-ideal internalization reduction program, a healthy weight management program, an expressive-writing control condition, or an assessment-only control condition. Participants completed diagnostic interviews and surveys at pretest, post-test, 6-month follow-up, and 12-month follow-up. Dissonance program effects on bulimic symptoms were stronger for participants with initial elevations in body image distress, bulimic symptoms, and thin-ideal internalization. Healthy weight program effects on bulimic symptoms were stronger for adolescents with initial elevations in body image distress, bulimic symptoms, readiness to change, body mass, and emotional eating. Overall, intervention effects tended to be amplified for high-risk versus low-risk adolescents. However, certain moderator effects appeared to be specific to the two different prevention programs.

2001-01-01

The increase of the orbital debris environment in low-earth orbit has prompted NASA to develop analytical tools for quantifying and lowering the likelihood of crew loss following orbital debris penetration of the International Space Station (ISS). NASA uses the Manned Spacecraft and Crew Survivability (MSCSurv) computer program to simulate the events that may cause crew loss following orbital debris penetration of ISS manned modules, including: (1) critical cracking (explosive decompression) of the module; (2) critical external equipment penetration (such as hydrazine and high pressure tanks); (3) critical internal system penetration (guidance, control, and other vital components); (4) hazardous payload penetration (furnaces, pressure bottles, and toxic substances); (5) crew injury (from fragments, overpressure, light flash, and temperature rise); (6) hypoxia from loss of cabin pressure; and (7) thrust from module hole causing high angular velocity (occurring only when key Guidance, Navigation, and Control (GN&C) equipment is damaged) and, thus, preventing safe escape vehicle (EV) departure. MSCSurv is also capable of quantifying the 'end effects' of orbital debris penetration, such as the likelihood of crew escape, the probability of each module depressurizing, and late loss of station control. By quantifying these effects (and their associated uncertainties), NASA is able to improve the likelihood of crew survivability following orbital debris penetration due to improved crew operations and internal designs.

Global robust output regulation control for cascaded nonlinear systems using the internal model principle

Yu, Jiang-Bo; Zhao, Yan; Wu, Yu-Qiang

2014-04-01

This article considers the global robust output regulation problem via output feedback for a class of cascaded nonlinear systems with input-to-state stable inverse dynamics. The system uncertainties depend not only on the measured output but also all the unmeasurable states. By introducing an internal model, the output regulation problem is converted into a stabilisation problem for an appropriately augmented system. The designed dynamic controller could achieve the global asymptotic tracking control for a class of time-varying reference signals for the system output while keeping all other closed-loop signals bounded. It is of interest to note that the developed control approach can be applied to the speed tracking control of the fan speed control system. The simulation results demonstrate its effectiveness.

Leadership and Cultural Challenges in Operating the International Space Station

2006-01-01

Operating the International Space Station (ISS) involves an indefinite, continuous series of long-duration international missions, and this requires an unprecedented degree of cooperation across multiple sites, organizations, and nations. ISS flight controllers have had to find ways to maintain effective team performance in this challenging new context. The goal of this study was to systematically identify and evaluate the major leadership and cultural challenges faces by ISS flight controllers, and to highlight the approaches that they have found most effective to surmount these challenges. We conducted a qualitative survey using a semi-structured interview. Subjects included 14 senior NASA flight controllers who were chosen on the basis of having had substantial experience working with international partners. Data were content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. To further explore the meaning of the interview findings, we also conducted some new analyses of data from a previous questionnaire study of Russian and American ISS mission control personnel. The interview data showed that respondents had substantial consensus on several leadership and cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Surprisingly few respondents offered strategies for addressing the challenge of working with team members whose native language is not American English. The questionnaire data showed that Americans think it is more important than Russians that mission control personnel speak the same dialect of one shared common language. Although specific to the ISS program, our results are consistent with recent management, cultural, and aerospace research. We aim to use our results to improve training for current and future ISS flight controllers.

Effects of internal friction on contact formation dynamics of polymer chain

NASA Astrophysics Data System (ADS)

Bian, Yukun; Li, Peng; Zhao, Nanrong

2018-04-01

A theoretical framework is presented to study the contact formation dynamics of polymer chains, in accompany with an electron-transfer quenching. Based on a non-Markovian Smoluchowski equation supplemented with an exponential sink term, we derive the mean time of contact formation under Wilemski-Fixman approximation. Our particular attentions are paid to the effect of internal friction. We find out that internal friction induces a novel fractional viscosity dependence, which will become more remarkable as internal friction increases. Furthermore, we clarify that internal friction inevitably promotes a diffusion-controlled mechanism by slowing the chain relaxation. Finally, we apply our theory to rationalise the experimental investigation for contact formation of a single-stranded DNA. The theoretical results can reproduce the experimental data very well with quite reasonable estimation for the intrinsic parameters. Such good agreements clearly demonstrate the validity of our theory which has appropriately addressed the very role of internal friction to the relevant dynamics.

Spanking, corporal punishment and negative long-term outcomes: a meta-analytic review of longitudinal studies.

PubMed

Ferguson, Christopher J

2013-02-01

Social scientists continue to debate the impact of spanking and corporal punishment (CP) on negative child outcomes including externalizing and internalizing behavior problems and cognitive performance. Previous meta-analytic reviews have mixed long- and short-term studies and relied on bivariate r, which may inflate effect sizes. The current meta-analysis focused on longitudinal studies, and compared effects using bivariate r and better controlled partial r coefficients controlling for time-1 outcome variables. Consistent with previous findings, results based on bivariate r found small but non-trivial long-term relationships between spanking/CP use and negative outcomes. Spanking and CP correlated .14 and .18 respectively with externalizing problems, .12 and .21 with internalizing problems and -.09 and -.18 with cognitive performance. However, when better controlled partial r coefficients (pr) were examined, results were statistically significant but trivial (at or below pr = .10) for externalizing (.07 for spanking, .08 for CP) and internalizing behaviors (.10 for spanking, insufficient studies for CP) and near the threshold of trivial for cognitive performance (-.11 for CP, insufficient studies for spanking). It is concluded that the impact of spanking and CP on the negative outcomes evaluated here (externalizing, internalizing behaviors and low cognitive performance) are minimal. It is advised that psychologists take a more nuanced approach in discussing the effects of spanking/CP with the general public, consistent with the size as well as the significance of their longitudinal associations with adverse outcomes.

Objectives The aim of this study was to determine the prediction of locus of control and self-esteem in academic achievement among the students. Materials and Methods This cross-sectional study was conducted on 300 college students in Kermanshah University of Medical Sciences in 2014. Data collection tools were in three sections: demographic, Rotter internal-external locus of control scale and Coopersmith self-esteem inventory. Data were analyzed using the SPSS software version 21. Results Results showed that 29.8% and 76.2% of the participants had internal locus of control, and high self-esteem, respectively. There was a significant correlation between self-esteem, locus of control and academic achievement of the students. Self-esteem accounted for 39.5% of the variation in academic achievement. Conclusions It seems that interventions to increase self-esteem among student can help improve academic achievement among them. PMID:27284277

Global partnerships are critical to advance the control of Neglected Zoonotic Diseases: The case of the Global Alliance for Rabies Control.

There is a need for innovation to improve control of all Neglected Zoonotic Diseases (NZDs). The Global Alliance for Rabies Control was formed to prevent human deaths from rabies and relieve the burden of rabies in other animal populations, especially dogs. It aims to identify reasons for the neglect of rabies in developing countries and to develop strategies to improve rabies control. Through initiatives such as World Rabies Day and the Partners for Rabies Prevention, progress has been made towards increased awareness of the burden of rabies transmitted by dogs at scales from local to international. An evidence base of the feasibility of canine rabies elimination has been built up and now easier access to information and tools enables countries to design and implement rabies elimination strategies in a logical way, utilizing the structures of regional networks for rabies control. The body of evidence has built consensus amongst international stakeholders in rabies control and is now being used to encourage international policy change, attract investment and increase delivery of effective rabies control programmes in canine rabies endemic countries.

The pain, depression, disability pathway in those with low back pain: a moderation analysis of health locus of control.

PubMed

Campbell, Paul; Hope, Kate; Dunn, Kate M

2017-01-01

Low back pain (LBP) is common, impacts on the individual and society, and is a major health concern. Psychological consequences of LBP, such as depression, are significant barriers to recovery, but mechanisms for the development of depression are less well understood. One potential mechanism is the individual's health locus of control (HLoC), that is, perception of the level of control an individual has over their health. The objective of this study is to investigate the moderation effect of HLoC on the pain-depression-disability pathway in those with LBP. The design is a nested cross-sectional analysis of two existing cohorts of patients (n=637) who had previously consulted their primary care physician about LBP. Measures were taken of HLoC, pain intensity and interference, depression, disability, and bothersomeness. Structural Equation Modeling analysis was applied to two path models that examined the pain to depression to disability pathway moderated by the HLoC constructs of Internality and Externality, respectively. Critical ratio (CR) difference tests were applied to the coefficients using pairwise comparisons. The results show that both models had an acceptable model fit and pathways were significant. CR tests indicated a significant moderation effect, with stronger pathway coefficients for depression for those who report low Internality (β 0.48), compared to those with high Internality (β 0.28). No moderation effects were found within the Externality model. HLoC Internality significantly moderates the pain-depression pathway in those with LBP, meaning that those who have a low perception of control report greater levels of depression. HLoC may signify depression among people with LBP, and could potentially be a target for intervention.

2001-01-01

In order to test the hypothesis that self study with a CD-ROM based cardiac auscultation tool would enhance knowledge and skills, we conducted a controlled trial of internal medicine residents and evaluated their performance on a test before and after exposure to the tool. Both intervention and control groups improved their auscultation knowledge and skills scores. However, subjects in the CD-ROM group had significantly higher improvements in skills, knowledge, and total scores than those not exposed to the intervention (all p<0.001). Therefore, protected time for internal medicine residents to use this multimedia computer program enhanced both facets of cardiac auscultation.

2010-01-01

Medical laboratories, and specifically genetic testing laboratories, provide vital medical services to different clients: clinicians requesting a test, patients from whom the sample was collected, public health and medical-legal instances, referral laboratories and authoritative bodies. All expect results that are accurate and obtained in an efficient and effective manner, within a suitable time frame and at acceptable cost. There are different ways of achieving the end results, but compliance with International Organization for Standardization (ISO) 15189, the international standard for the accreditation of medical laboratories, is becoming progressively accepted as the optimal approach to assuring quality in medical testing. We present recommendations and strategies designed to aid genetic testing laboratories with the implementation of a quality management system, including key aspects such as document control, external quality assessment, internal quality control, internal audit, management review, validation, as well as managing the human side of change. The focus is on pragmatic approaches to attain the levels of quality management and quality assurance required for accreditation according to ISO 15189, within the context of genetic testing. Attention is also given to implementing efficient and effective quality improvement. PMID:20720559

Fibromyalgia is a disabling syndrome. Results obtained with different therapies are very limited to date. The goal of this study was to verify whether the application of a mindfulness-based training program was effective in modifying anger, anxiety, and depression levels in a group of women diagnosed with fibromyalgia. This study is an experimental trial that employed a waiting list control group. Measures were taken at three different times: pretest, posttest, and follow-up. The statistical analyses revealed a significant reduction of anger (trait) levels, internal expression of anger, state anxiety, and depression in the experimental group as compared to the control group, as well as a significant increase in internal control of anger. It can be concluded that the mindfulness-based treatment was effective after 7 weeks. These results were maintained 3 months after the end of the intervention.

Simple adaptive control system design for a quadrotor with an internal PFC

Mizumoto, Ikuro; Nakamura, Takuto; Kumon, Makoto

2014-12-10

The paper deals with an adaptive control system design problem for a four rotor helicopter or quadrotor. A simple adaptive control design scheme with a parallel feedforward compensator (PFC) in the internal loop of the considered quadrotor will be proposed based on the backstepping strategy. As is well known, the backstepping control strategy is one of the advanced control strategy for nonlinear systems. However, the control algorithm will become complex if the system has higher order relative degrees. We will show that one can skip some design steps of the backstepping method by introducing a PFC in the inner loopmore » of the considered quadrotor, so that the structure of the obtained controller will be simplified and a high gain based adaptive feedback control system will be designed. The effectiveness of the proposed method will be confirmed through numerical simulations.« less

Thermoelastic Damping in FGM Nano-Electromechanical System in Axial Vibration Based on Eringen Nonlocal Theory

Rahimi, Z.; Rashahmadi, S.

2017-11-01

The thermo-elastic damping is a dominant source of internal damping in micro-electromechanical systems (MEMS) and nano-electromechanical systems (NEMS). The internal damping cannot neither be controlled nor minimized unless either mechanical or geometrical properties are changed. Therefore, a novel FGMNEM system with a controllable thermo-elastic damping of axial vibration based on Eringen nonlocal theory is considered. The effects of different parameter like the gradient index, nonlocal parameter, length of nanobeam and ambient temperature on the thermo-elastic damping quality factor are presented. It is shown that the thermo-elastic damping can be controlled by changing different parameter.

Randomized controlled trial, To compare changes in shoulder internal rotation range of motion (ROM), for 2 stretching exercises, the "cross-body stretch" and the "sleeper stretch," in individuals with posterior shoulder tightness. Recently, some authors have expressed the belief that the sleeper stretch is better than the cross-body stretch to address glenohumeral posterior tightness because the scapula is stabilized. Fifty-four asymptomatic subjects (20 males, 34 females) participated in the study. The control group (n=24) consisted of subjects with a between-shoulder difference in internal rotation ROM of less than 10 degrees, whereas those subjects with more than a 10 degrees difference were randomly assigned to 1 of 2 intervention groups, the sleeper stretch group (n=15) or the cross-body stretch group (n=15). Shoulder internal rotation ROM, with the arm abducted to 90 degrees and scapula motion prevented, was measured before and after a 4-week intervention period. Subjects in the control group were asked not to engage in any new stretching activities, while subjects in the 2 stretching groups were asked to perform stretching exercises on the more limited side only, once daily for 5 repetitions, holding each stretch for 30 seconds. The improvements in internal rotation ROM for the subjects in the cross-body stretch group (mean +/- SD, 20.0 degrees +/- 12.9 degrees) were significantly greater than for the subjects in the control group (5.9 degrees +/- 9.4 degrees, P = .009). The gains in the sleeper stretch group (12.4 degrees +/- 10.4 degrees) were not significant compared to those of the control group (P = .586) and those of the cross-body stretch group (P = .148). The cross-body stretch in individuals with limited shoulder internal rotation ROM appears to be more effective than no stretching in controls without internal rotation asymmetry to improve shoulder internal rotation ROM. While the improvement in internal rotation from the cross-body stretch was greater than for the sleeper stretch and of a magnitude that could be clinically significant, the small sample size likely precluded statistical significance between groups.

The outbreak of highly pathogenic H5N1 avian influenza, with its international spread, confirmed that emerging infectious disease control must be underpinned by effective laboratory services. Laboratory results are the essential data underpinning effective surveillance, case diagnosis, or monitoring of responses. Importantly, laboratories are best managed within national and international networks of technological support rather than in isolation. A well planned laboratory network can deliver both a geographical spread of testing capacity and also a cost effective hierarchy of capability. Hence in the international context regional networks can be particularly effective. Laboratories are an integral part of a country's veterinary services and their role and function should be clearly defined in the national animal health strategy and supporting government policies. Not every laboratory should be expected to deliver every possible service, and integration into regional and broader international networks should be a part of the overall strategy. The outputs required of each laboratory should be defined and then ensured through accredited quality assurance. The political and scientific environment in which laboratories operate changes continuously, not only through evolving national and regional animal health priorities but also through new test technologies and enhancements to existing technologies. Active networks help individual laboratories to monitor, evaluate, and respond to such challenges and opportunities. The end result is enhanced emerging infectious disease preparedness across the region.

2017-05-26

The micromirror based on micro-electro-mechanical systems (MEMS) technology is widely employed in different areas, such as scanning, imaging and optical switching. This paper studies the MEMS electromagnetic micromirror for scanning or imaging application. In these application scenarios, the micromirror is required to track the command sinusoidal signal, which can be converted to an output regulation problem theoretically. In this paper, based on the internal model principle, the output regulation problem is solved by designing a robust controller that is able to force the micromirror to track the command signal accurately. The proposed controller relies little on the accuracy of the model. Further, the proposed controller is implemented, and its effectiveness is examined by experiments. The experimental results demonstrate that the performance of the proposed controller is satisfying.

We investigated the relationship between internalized stigma of mental illness at baseline and depressive and psychotic symptoms 3 and 6 months later, controlling for baseline symptoms. Data on homeless veterans with severe mental illness (SMI) were provided by the Northeast Program Evaluation Center (NEPEC) Special Needs-Chronic Mental Illness (SN-CMI) study (Kasprow and Rosenheck, 2008). The study used the Internalized Stigma of Mental Illness (ISMI) scale to measure internalized stigma at baseline and the Symptom Checklist-90-R (SCL-90-R) to measure depressive and psychotic symptoms at baseline and 3 and 6 month follow-ups. Higher levels of internalized stigma were associated with greater levels of depressive and psychotic symptoms 3 and 6 months later, even controlling for symptoms at baseline. Alienation and Discrimination Experience were the subscales most strongly associated with symptoms. Exploratory analyses of individual items yielded further insight into characteristics of potentially successful interventions that could be studied. Overall, our findings show that homeless veterans with SMI experiencing higher levels of internalized stigma are likely to experience more depression and psychosis over time. This quasi-experimental study replicates and extends findings of other studies and has implications for future controlled research into the potential long-term effects of anti-stigma interventions on mental health recovery.

We determined the effect of Prostataplex in men with lower urinary tract symptoms associated with benign prostatic hyperplasia. A total of 92 Chinese men between 49 and 75 years old with lower urinary tract symptoms were randomly assigned in this double-blind, placebo controlled trial. The 46 patients in the intervention group were given 2 Prostataplex soft gels daily for 12 weeks, while the 46 in the control group were given 2 placebo soft gels for the same time. The treated and control groups appeared to have more than a 95% compliance rate, as judged by counting the remaining pills in the bottle collected at the end of trial months 1 to 3. After 12 weeks of intervention the mean +/- SD maximum urinary flow rate was significantly higher in the treatment group than in the control group (14.07 +/- 2.56 vs 11.74 +/- 1.23 ml per second, p <0.001), while relative urinary resistance was significantly lower in the treatment group than in the control group (2.35 +/- 0.83 vs 3.02 +/- 1.18, p = 0.002). While there was no significant difference in mean prostate volume or International Prostate Symptom Score between the 2 groups, 18 of 46 patients (39.1%) in the treatment group showed an International Prostate Symptom Score improvement (decrease of 3 or greater) after intervention, whereas only 1 of 46 (2.2%) in the control group showed an International Prostate Symptom Score improvement (chi-square test p <0.001). Prostataplex may have short-term effects in improving symptoms and objective measures in Chinese men with lower urinary tract symptoms associated with benign prostatic hyperplasia.

Maternal communicative functions and mind-mindedness at 16 months as predictors of children's internal and non-internal language at 20 months.

Longobardi, Emiddia; Spataro, Pietro; Colonnesi, Cristina

2018-02-01

The effects of Communicative functions and Mind-Mindedness on children's language development have been typically investigated in separate studies. The present longitudinal research was therefore designed to yield new insight into the simultaneous impact of these two dimensions of maternal responsiveness on the acquisition of expressive language skills in a sample of 25 mother-child dyads. The frequencies of five communicative functions (Tutorial, Didactic, Conversational, Control and Asynchronous) and two types of mind-related comments (attuned vs. non-attuned) were assessed from a 15-min play session at 16 months. Children's expressive language was examined at both 16 months (number of word types and tokens produced, and number of words attributed to the child in the Questionnaire for Communication and Early Language development) and 20 months (number of internal and non-internal words attributed to the child in the Italian version of the Mac Arthur-Bates Communicative Development Inventory). The main finding was that mothers' use of attuned mind-related comments at 16 months predicted internal state language at 20 months, above and beyond the effects of CFs and children's linguistic ability at 16 months; in addition, mothers' Tutorial function at 16 months marginally predicted non-internal state language at 20 months, after controlling for MM and children's linguistic ability at 16 months. These results suggest that different expressions of maternal responsiveness influence distinct aspects of children's expressive language in the second year of life, although the effects of MM appear to be more robust.

The HBT-EP active mode control research program aims to: (i) advance understanding of the effects of 3D shaping on advanced tokamak fusion performance, (ii) resolve important MHD issues associated with disruptions, and (iii) measure and mitigate the effects of 3D scrape-off layer (SOL) currents through active and passive control of the plasma edge and conducting boundary structures. Comparison of kink mode structure and RMP response in circular versus diverted plasmas shows good agreement with DCON modeling. SOL current measurements have been used to study SOL current dynamics and current-sharing with the vacuum vessel wall during kink-mode growth and disruptions. A multi-chord extreme UV/soft X-ray array is being installed to provide detailed internal mode structure information. Internal local electrodes were used to apply local bias voltage at two radial locations to study the effect of rotation profile on MHD mode rotation and stability and radial current flow through the SOL. A GPU-based low latency control system using 96 inputs and 64 outputs to apply magnetic perturbations for active control of kink modes is extended to directly control the SOL currents for kink-mode control. An extensive array of SOL current monitors and edge drive electrodes are being installed for pioneering studies of helical edge current control. Supported by U.S. DOE Grant DE-FG02-86ER53222.

Copepod Behavior Response in an Internal Wave Apparatus

Webster, D. R.; Jung, S.; Haas, K. A.

2017-11-01

This study is motivated to understand the bio-physical forcing in zooplankton transport in and near internal waves, where high levels of zooplankton densities have been observed in situ. A laboratory-scale internal wave apparatus was designed to create a standing internal wave for various physical arrangements that mimic conditions observed in the field. A theoretical analysis of a standing internal wave inside a two-layer stratification system including non-linear wave effects was conducted to derive the expressions for the independent variables controlling the wave motion. Focusing on a case with a density jump of 1.0 σt, a standing internal wave was generated with a clean interface and minimal mixing across the pycnocline. Spatial and frequency domain measurements of the internal wave were evaluated in the context of the theoretical analysis. Behavioral assays with a mixed population of three marine copepods were conducted in control (stagnant homogeneous fluid), stagnant density jump interface, and internal wave flow configurations. In the internal wave treatment, the copepods showed an acrobatic, orbital-like motion in and around the internal wave region (bounded by the crests and the troughs of the waves). Trajectories of passive, neutrally-buoyant particles in the internal wave flow reveal that they generally oscillate back-and-forth along fixed paths. Thus, we conclude that the looping, orbital trajectories of copepods in the region near the internal wave interface are due to animal behavior rather than passive transport.

This pilot study evaluated a body image intervention for men, Body Project M. Seventy-four British undergraduate men took part in two 90-min intervention sessions, and completed standardised assessments of body image, bulimic pathology, and related outcomes at baseline, post-intervention, and 3-month follow-up. Fifty-three other men completed the questionnaires as an assessment-only control group. Per-protocol analysis showed that Body Project M improved men's dissatisfaction with body fat and muscularity, body appreciation, muscularity enhancing behaviours, appearance comparisons, and internalization (ds=0.46-0.80) at post-intervention. All except dissatisfaction with muscularity and internalization were sustained at 3-month follow-up. No effects were found for bulimic pathology. Post-intervention effects for dissatisfaction with muscularity and internalization only were retained under intention-to-treat analysis. Participants were favourable towards the intervention. This study provides preliminary evidence for the acceptability and post-intervention efficacy of Body Project M. Further development of the intervention is required to improve and sustain effects.

Abstract Purpose To review the evidence basis of international aid and health policy. Context of case Current international aid policy is largely neoliberal in its promotion of commoditization and privatisation. We review this policy's responsibility for the lack of effectiveness in disease control and poor access to care in low and middle-income countries. Data sources National policies, international programmes and pilot experiments are examined in both scientific and grey literature. Conclusions and discussion We document how health care privatisation has led to the pool of patients being cut off from public disease control interventions—causing health care disintegration—which in turn resulted in substandard performance of disease control. Privatisation of health care also resulted in poor access. Our analysis consists of three steps. Pilot local contracting-out experiments are scrutinized; national health care records of Colombia and Chile, two countries having adopted contracting-out as a basis for health care delivery, are critically examined against Costa Rica; and specific failure mechanisms of the policy in low and middle-income countries are explored. We conclude by arguing that the negative impact of neoliberal health policy on disease control and health care in low and middle-income countries justifies an alternative aid policy to improve both disease control and health care.

Cancer Control Programs in East Asia: Evidence From the International Literature

PubMed Central

Moore, Malcolm A.

2014-01-01

Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

Locus of control and utilization of social support among mothers of young children with physical disabilities.

PubMed

Rimmerman, A; Stanger, V

1992-01-01

Sixty mothers of young children with physical disabilities were studied with respect to the effect of the mothers' locus of control on the utilization of social support. The initial findings failed to support the thesis that mothers with an 'internally' focused locus of control would demonstrate greater utilization of their support system, both in terms of descriptive and functional measures. A secondary analysis showed that the mothers' age, the children's level of functioning, and the existence of additional members of the family with a disability served as intervening variables. Only among older mothers, who perceived their children's functioning as severe, was there significant association between the locus of control ('internal') and greater use of their social support system. 'Internal' mothers who had no additional extended family members with a disability reported higher levels of functional social support, as compared to 'external' mothers. Findings are interpreted with respect to social support theory and its implications to applied research.

Internal versus external controls on age variability: Definitions, origins and implications in a changing climate

The unsteadiness of stream water age is now well established, but the controls on the age dynamics, and the adequate representation and prediction of those dynamics, are not. A basic distinction can be made between internal variability that arises from changes in the proportions of flow moving through the diverse flow pathways of a hydrologic system, and external variability that arises from the stochasticity of inputs and outputs (such as precipitation and streamflow). In this talk I will show how these two types of age variability can be formally defined and distinguished within the framework of rank StorAge Selection (rSAS) functions. Internal variability implies variations in time in the rSAS function, while external variability does not. This leads naturally to the definition of several modes of internal variability, reflecting generic ways that system flowpaths may be rearranged. This rearrangement may be induced by fluctuations in the system state (such as catchment wetness), or by longer-term changes in catchment structure (such as land use change). One type of change, the 'inverse storage effect' is characterized by an increase in the release of young water from the system in response to an increase in overall system storage. This effect can be seen in many hydrologic settings, and has important implications for the effect of altered hydroclimatic conditions on solute transport through a landscape. External variability, such as increased precipitation, can induce a decrease in mean transit time (and vice versa), but this effect is greatly enhanced if accompanied by an internal shift in flow pathways that increases the relative importance of younger water. These effects will be illustrated using data from field and experimental studies.

In this talk I will show how these two types of age variability can be formally defined and distinguished within the framework of rank StorAge Selection (rSAS) functions. Internal variability implies variations in time in the rSAS function, while external variability does not. This leads naturally to the definition of several modes of internal variability, reflecting generic ways that system flowpaths may be rearranged. This rearrangement may be induced by fluctuations in the system state (such as catchment wetness), or by longer-term changes in catchment structure (such as land use change). One type of change, the 'inverse storage effect' is characterized by an increase in the release of young water from the system in response to an increase in overall system storage. This effect can be seen in many hydrologic settings, and has important implications for the effect of altered hydroclimatic conditions on solute transport through a landscape. External variability, such as increased precipitation, can induce a decrease in mean transit time (and vice versa), but this effect is greatly enhanced if accompanied by an internal shift in flow pathways that increases the relative importance of younger water. These effects will be illustrated using data from field and experimental studies.

Randomized controlled trials are one of the most reliable resources for assessing the effectiveness and safety of medical treatments. Low quality randomized controlled trials carry a large bias that can ultimately impair the reliability of their conclusions. The present study aimed to evaluate the quality of randomized controlled trials published in International Journal of Urology by using multiple quality assessment tools. Randomized controlled trials articles published in International Journal of Urology were found using the PubMed MEDLINE database, and qualitative analysis was carried out with three distinct assessment tools: the Jadad scale, the van Tulder scale and the Cochrane Collaboration Risk of Bias Tool. The quality of randomized controlled trials was analyzed by publication year, type of subjects, intervention, presence of funding and whether an institutional review board reviewed the study. A total of 68 randomized controlled trial articles were published among a total of 1399 original articles in International Journal of Urology. Among these randomized controlled trials, 10 (2.70%) were from 1994 to 1999, 23 (4.10%) were from 2000 to 2005 and 35 (4.00%) were from 2006 to 2011 (P = 0.494). On the assessment with the Jadad and van Tulder scale, the numbers and percentage of high quality randomized controlled trials increased over time. The studies that had institutional review board reviews, funding resources or that were carried out in multiple institutions had an increased percentage of high quality articles. The numbers and percentage of high-quality randomized controlled trials published in International Journal of Urology have increased over time. Furthermore, randomized controlled trials with funding resources, institutional review board reviews or carried out in multiple institutions have been found to be of higher quality compared with others not presenting these features. © 2013 The Japanese Urological Association.

Background Research suggests that personality traits have both direct and indirect effects on the development of psychological symptoms, with indirect effects mediated by stressful or traumatic events. This study models the direct influence of personality traits on residualized changes in internalizing and externalizing symptoms following a stressful and potentially traumatic deployment, as well as the indirect influence of personality on symptom levels mediated by combat exposure. Method We utilized structural equation modeling with a longitudinal prospective study of 522 US National Guard soldiers deployed to Iraq. Analyses were based on self-report measures of personality, combat exposure, and internalizing and externalizing symptoms. Results Both pre-deployment Disconstraint and externalizing symptoms predicted combat exposure, which in turn predicted internalizing and externalizing symptoms. There was a significant indirect effect for pre-deployment externalizing symptoms on post-deployment externalizing via combat exposure (p < .01). Negative Emotionality and pre-deployment internalizing symptoms directly predicted post-deployment internalizing symptoms, but both were unrelated to combat exposure. No direct effects of personality on residualized changes in externalizing symptoms were found. Conclusions Baseline symptom dimensions had significant direct and indirect effects on post-deployment symptoms. Controlling for both pre-exposure personality and symptoms, combat experiences remained positively related to both internalizing and externalizing symptoms. Implications for diagnostic classification are discussed. PMID:26347314

Verbal monitoring in Parkinson’s disease: A comparison between internal and external monitoring

Patients with Parkinson’s disease (PD) display a variety of impairments in motor and non-motor language processes; speech is decreased on motor aspects such as amplitude, prosody and speed and on linguistic aspects including grammar and fluency. Here we investigated whether verbal monitoring is impaired and what the relative contributions of the internal and external monitoring route are on verbal monitoring in patients with PD relative to controls. Furthermore, the data were used to investigate whether internal monitoring performance could be predicted by internal speech perception tasks, as perception based monitoring theories assume. Performance of 18 patients with Parkinson’s disease was measured on two cognitive performance tasks and a battery of 11 linguistic tasks, including tasks that measured performance on internal and external monitoring. Results were compared with those of 16 age-matched healthy controls. PD patients and controls generally performed similarly on the linguistic and monitoring measures. However, we observed qualitative differences in the effects of noise masking on monitoring and disfluencies and in the extent to which the linguistic tasks predicted monitoring behavior. We suggest that the patients differ from healthy subjects in their recruitment of monitoring channels. PMID:28832595

Update in the methodology of the chronic stress paradigm: internal control matters

PubMed Central

2011-01-01

To date, the reliability of induction of a depressive-like state using chronic stress models is confronted by many methodological limitations. We believe that the modifications to the stress paradigm in mice proposed herein allow some of these limitations to be overcome. Here, we discuss a variant of the standard stress paradigm, which results in anhedonia. This anhedonic state was defined by a decrease in sucrose preference that was not exhibited by all animals. As such, we propose the use of non-anhedonic, stressed mice as an internal control in experimental mouse models of depression. The application of an internal control for the effects of stress, along with optimized behavioural testing, can enable the analysis of biological correlates of stress-induced anhedonia versus the consequences of stress alone in a chronic-stress depression model. This is illustrated, for instance, by distinct physiological and molecular profiles in anhedonic and non-anhedonic groups subjected to stress. These results argue for the use of a subgroup of individuals who are negative for the induction of a depressive phenotype during experimental paradigms of depression as an internal control, for more refined modeling of this disorder in animals.

OBJECTIVES To evaluate the effects of a brief educational program on beliefs, knowledge, and behaviors related to skin cancer control among internal medicine housestaff and attending physicians. DESIGN Randomized controlled trial. SETTING Urban academic general medicine practice. PARTICIPANTS Internal medicine housestaff and attending physicians with continuity clinics at the practice site. INTERVENTION Two 1-hour educational seminars on skin cancer control conducted jointly by a general internist and a dermatologist. MEASUREMENTS AND MAIN RESULTS Self-reported attitudes and beliefs about skin cancer control, ability to identify and make treatment decisions on 18 skin lesions, and knowledge of skin cancer risk factors were measured by a questionnaire before and after the teaching intervention. Exit surveys of patients at moderate to high risk of skin cancer were conducted 1 month before and 1 month after the intervention to measure physician skin cancer control practices reported by patients. Eighty-two physicians completed baseline questionnaires and were enrolled in the study, 46 in the intervention group and 36 in the control group. Twenty-five physicians attended both sessions, 11 attended one, and 10 attended neither. Postintervention, the percentage of physicians feeling adequately trained increased from 35% to 47% in the control group ( p = .34) and from 37% to 57% in the intervention group ( p = .06). Intervention physicians had an absolute mean improvement in their risk factor identification score of 6.7%, while control physicians’ mean score was unchanged ( p = .06). Intervention and control physicians had similar increases in their postintervention lesion identification and management scores. Postintervention, the mean proportion of patients per physician stating they were advised to watch their moles increased more among intervention physicians than control physicians (absolute difference of 19% vs −8%, p = .04). Other changes in behavior were not significant. CONCLUSIONS Although we observed a few modest intervention effects, overall this brief skin cancer education intervention did not significantly affect primary care physicians’ skin cancer control attitudes, beliefs, knowledge, or behaviors. A more intensive intervention with greater participation may be necessary to show a stronger impact on attitudes and knowledge about skin cancer control among primary care physicians. PMID:9294786

The development of PTX, monolithic catalytic exhaust purifiers, is outlined, and their first use for exhaust emissions control of commercial equipment is described. The main use of PTX converters is on forklift trucks. The purification achievable with PTX-equipped fork-lift trucks under various operational conditions is discussed, and examples from the field are given. During more than ten years of operation, no adverse health effects have been reported, and PTX-equipped internal combustion engines appear safe for use in confined areas. PMID:50933

Testing a dissonance body image intervention among young girls.

2014-02-01

Body image and eating disorder interventions based on cognitive dissonance have been shown to be effective among girls and women aged 14 and above. This article reports a preliminary examination of whether a dissonance intervention is also effective when delivered in a school setting to 12- and 13-year-old girls in the United Kingdom. Girls (N = 106, mean age = 12.07 years, SD = .27) were allocated to the intervention condition or a waitlist control. In contrast to the control group, girls in the intervention condition reported significant reductions in body dissatisfaction and internalization of a thin body ideal post-intervention. There was no significant change in self-reported dietary restraint for either condition. In addition, compared with the control group, girls in the intervention condition showed increased resilience to negative media effects 1-month post-intervention. Results suggests that dissonance based programs can reduce body dissatisfaction, internalization and negative media effects among a younger group of girls than previously examined and in a United Kingdom school setting.

This study analyzed the unique effects of gender and culture on psychopathology in adolescents from seven countries after controlling for factors which might have contributed to variations in psychopathology. In a sample 2259 adolescents (M = 15 years; 54% female) from France, Germany, Turkey, Greece, Peru, Pakistan, and Poland identity stress, coping with identity stress, maternal parenting (support, psychological control, anxious rearing) and psychopathology (internalizing, externalizing and total symptomatology) were assessed. Due to variations in stress perception, coping style and maternal behavior, these covariates were partialed out before the psychopathology scores were subjected to analyses of variance with gender and country as factors. These analyses leveled out the main effect of country and revealed country-specific gender effects. In four countries, males reported higher internalizing and total symptomatology than females. Partialing out the covariates resulted in a clearer picture of culture-specific and gender-dependent effects on psychopathology, which is helpful in designing interventions.

To test whether the experience of being bullied has an environmentally mediated effect on internalizing symptoms in young children. A genetically informative, longitudinal 1994-1995 birth cohort. A nationally representative sample from the United Kingdom. We examined 1116 twin pairs who are participants in the Environmental Risk Longitudinal Twin Study. Main Exposure The experience of being bullied between the ages of 7 and 9 years. Mothers' and teachers' reports of children's internalizing problems at 7 and 10 years of age. Monozygotic twins who had been bullied had more internalizing symptoms (mean, 0.23; SD, 1.00) compared with their co-twin who had not been bullied (mean, -0.13; SD, 0.86), indicating that being bullied has an environmentally mediated effect on children's internalizing problems (beta, 0.36 [95% confidence interval (CI), 0.18-0.54]). This effect remained significant after controlling for preexisting internalizing problems (beta, 0.26 [95% CI, 0.09-0.44]). Being bullied at a young age is an environmentally mediated contributing factor to children's internalizing problems. Intervention programs aimed at reducing bullying behavior in schools and in the community have the potential to influence children's early symptoms of mental health problems.

Perceptions of government knowledge and control over contributions of aid organizations and INGOs to health in Nepal: a qualitative study.

PubMed

2013-01-18

Almost 50% of the Nepali health budget is made up of international aid. International Non-Governmental Organizations working in the field of health are able to channel their funds directly to grass root level. During a 2010 conference, the Secretary of Population stated that the government has full knowledge and control over all funds and projects coming to Nepal. However, there are no documents to support this. The study aims to assess government and partner perceptions on whether Government of Nepal currently has full knowledge of contributions of international aid organizations and International Non-Governmental Organizations to health in Nepal and to assess if the government is able to control all foreign contributions to fit the objectives of Second Long Term Health Plan (1997-2017). A qualitative study was performed along with available literature review. Judgmental and snowball sampling led to 26 in depth interviews with key informants from the government, External Development Partners and International Non-Governmental Organizations. Results were triangulated based on source of data. Representatives of the Department of Health Services declined to be interviewed. Data collection was done until researchers felt data saturation had been reached with each group of key informants. While Ministry of Health and Population leads the sector wide approach that aims to integrate all donor and International Non-Governmental Organization contributions to health and direct them to the government's priority areas, questions were raised around its capacity to do so. Similarly, informants questioned the extent to which Social Welfare Council was able to control all International Non-Governmental Organizations contributions. Political tumult, corruption in the government, lack of human resources in the government, lack of coordination between government bodies, convoluted bureaucracy, and unreliability of donor and International Non-Governmental Organization contributions were identified as the main reasons for difficulties in aid integration. Despite its commitment to coordinate and control development assistance to the health sector, and its leadership position of the Sector Wide Approach, complete knowledge and effective coordination of all international contributions remains a challenge and is hampered by issues within the government as well as among External Development Partners and International Non-Governmental Organizations.

We used sex, observed parenting quality at 18 months, and three variants of the catechol-O-methyltransferase gene (Val158Met [rs4680], intron1 [rs737865], and 3′-untranslated region [rs165599]) to predict mothers’ reports of inhibitory and attentional control (assessed at 42, 54, 72, and 84 months) and internalizing symptoms (assessed at 24, 30, 42, 48, and 54 months) in a sample of 146 children (79 male). Although the pattern for all three variants was very similar, Val158Met explained more variance in both outcomes than did intron1, the 3′-untranslated region, or a haplotype that combined all three catechol-O-methyltransferase variants. In separate models, there were significant three-way interactions among each of the variants, parenting, and sex, predicting the intercepts of inhibitory control and internalizing symptoms. Results suggested that Val158Met indexes plasticity, although this effect was moderated by sex. Parenting was positively associated with inhibitory control for methionine–methionine boys and for valine–valine/valine–methionine girls, and was negatively associated with internalizing symptoms for methionine–methionine boys. Using the “regions of significance” technique, genetic differences in inhibitory control were found for children exposed to high-quality parenting, whereas genetic differences in internalizing were found for children exposed to low-quality parenting. These findings provide evidence in support of testing for differential susceptibility across multiple outcomes. PMID:25159270

Knee joint position sense ability in elite athletes who have returned to international level play following ACL reconstruction: A cross-sectional study.

PubMed

Relph, Nicola; Herrington, Lee

2016-12-01

Following an ACL injury, reconstruction (ACL-R) and rehabilitation, athletes may return to play with a proprioceptive deficit. However, literature is lacking to support this hypothesis in elite athletic groups who have returned to international levels of performance. It is possible the potentially heightened proprioceptive ability evidenced in athletes may negate a deficit following injury. The purpose of this study was to consider the effects of ACL injury, reconstruction and rehabilitation on knee joint position sense (JPS) on a group of elite athletes who had returned to international performance. Using a cross-sectional design ten elite athletes with ACL-R and ten controls were evaluated. JPS was tested into knee extension and flexion using absolute error scores. Average data with 95% confidence intervals between the reconstructed, contralateral and uninjured control knees were analyzed using t-tests and effect sizes. The reconstructed knee of the injured group demonstrated significantly greater angle of error scores when compared to the contralateral and uninjured control into knee flexion (p=0.0001, r=0.98) and knee extension (p=0.0001, r=0.91). There were no significant differences between the contralateral uninjured knee of the injured group and the uninjured control group. Elite athletes who have had an ACL injury, reconstruction, rehabilitation and returned to international play demonstrate lower JPS ability compared to control groups. It is unclear if this deficiency affects long-term performance or secondary injury and re-injury problems. In the future physical therapists should monitor athletes longitudinally when they return to play. Copyright © 2016 Elsevier B.V. All rights reserved.

Amutio, Alberto; Franco, Clemente; Pérez-Fuentes, María de Carmen; Gázquez, José J.; Mercader, Isabel

2015-01-01

Fibromyalgia is a disabling syndrome. Results obtained with different therapies are very limited to date. The goal of this study was to verify whether the application of a mindfulness-based training program was effective in modifying anger, anxiety, and depression levels in a group of women diagnosed with fibromyalgia. This study is an experimental trial that employed a waiting list control group. Measures were taken at three different times: pretest, posttest, and follow-up. The statistical analyses revealed a significant reduction of anger (trait) levels, internal expression of anger, state anxiety, and depression in the experimental group as compared to the control group, as well as a significant increase in internal control of anger. It can be concluded that the mindfulness-based treatment was effective after 7 weeks. These results were maintained 3 months after the end of the intervention. PMID:25628591

1990-01-01

This study tested the effectiveness of two conceptually different chart audit-based approaches to modifying physicians' clinical practices to conform with quality-assurance standards. The objective was to increase intern utilization of cholesterol management opportunities in the inpatient setting. Using a clinical trial study design, 29 internal medicine interns were randomly assigned to four intervention groups identified by the intervention they received: control, reminder checklists (checklists), patient-specific feedback (feedback), or both interventions (combined). Over a nine-month period, intern management of high blood cholesterol levels in internal medicine inpatients (n = 459) was monitored by postdischarge chart audit. During both a baseline and subsequent intervention period, interns documented significantly more cholesterol management for inpatients with coronary artery disease (CAD) than without CAD. During baseline, 27.3%, 24.3%, 21.7%, 12.4%, 5.4%, and 2.7% of all inpatient charts had intern documentation concerning a low-fat hospital diet, cholesterol history, screening blood cholesterol level assessment, follow-up lipid profile, nutritionist consult, and preventive cardiology consult, respectively. The feedback intervention significantly increased overall intern-documented cholesterol management among inpatients with CAD. The checklists significantly decreased overall intern-documented cholesterol management. Feedback appears to be an effective approach to increasing intern cholesterol management in inpatients.

The influence of motion control shoes on the running gait of mature and young females.

PubMed

Lilley, Kim; Stiles, Vicky; Dixon, Sharon

2013-03-01

This study compared the running gait of mature and young females, and investigated the effect of a motion control shoe. First, it was hypothesised that in a neutral shoe, mature females would display significantly greater rearfoot eversion, knee internal rotation and external adductor moments when compared to a younger group. Secondly, the motion control shoe would reduce rearfoot eversion and knee internal rotation in both groups. Thirdly it was hypothesised that the motion control shoe would increase knee external adductor moment, through an increase in knee varus and moment arm. 15 mature (40-60 years) and 15 young (18-25 years) females performed 10 running trials at 3.5ms(-1)±5% over a force platform. Two shoes were tested, the Adidas Supernova Glide (neutral), and the Adidas Supernova Sequence (motion control). Ankle and knee joint dynamics were analysed for the right leg, and the mean of ten trials was calculated. Joint moments were calculated using inverse dynamics. In the neutral condition, mature females presented greater peak rearfoot eversion, knee internal rotation, and external adductor moments than young females (p<0.05). A motion control shoe significantly reduced peak rearfoot eversion and knee internal rotation among both groups (p<0.05). No between shoe differences in knee external adductor moment were observed. A motion control shoe is recommended to reduce risk of injury associated with rearfoot eversion and knee internal rotation in mature females. However since the knee external adductor moment is a variable commonly associated with medial knee loading it is suggested that alternative design features are required to influence this moment.

Development of Internal Controls for the Luminex Instrument as Part of a Multiplex Seven-Analyte Viral Respiratory Antibody Profile

Martins, Thomas B.

2002-01-01

The ability of the Luminex system to simultaneously quantitate multiple analytes from a single sample source has proven to be a feasible and cost-effective technology for assay development. In previous studies, my colleagues and I introduced two multiplex profiles consisting of 20 individual assays into the clinical laboratory. With the Luminex instrument’s ability to classify up to 100 distinct microspheres, however, we have only begun to realize the enormous potential of this technology. By utilizing additional microspheres, it is now possible to add true internal controls to each individual sample. During the development of a seven-analyte serologic viral respiratory antibody profile, internal controls for detecting sample addition and interfering rheumatoid factor (RF) were investigated. To determine if the correct sample was added, distinct microspheres were developed for measuring the presence of sufficient quantities of immunoglobulin G (IgG) or IgM in the diluted patient sample. In a multiplex assay of 82 samples, the IgM verification control correctly identified 23 out of 23 samples with low levels (<20 mg/dl) of this antibody isotype. An internal control microsphere for RF detected 30 out of 30 samples with significant levels (>10 IU/ml) of IgM RF. Additionally, RF-positive samples causing false-positive adenovirus and influenza A virus IgM results were correctly identified. By exploiting the Luminex instrument’s multiplexing capabilities, I have developed true internal controls to ensure correct sample addition and identify interfering RF as part of a respiratory viral serologic profile that includes influenza A and B viruses, adenovirus, parainfluenza viruses 1, 2, and 3, and respiratory syncytial virus. Since these controls are not assay specific, they can be incorporated into any serologic multiplex assay. PMID:11777827

On July 1, 2011, the Accreditation Council for Graduate Medical Education implemented further restrictions of its 2003 regulations on duty hours and supervision. It remains unclear if the 2003 regulations improved trainee well-being or patient safety. To determine the effects of the 2011 Accreditation Council for Graduate Medical Education duty hour regulations compared with the 2003 regulations concerning sleep duration, trainee education, continuity of patient care, and perceived quality of care among internal medicine trainees. Crossover study design in an academic research setting. Medical house staff. General medical teams were randomly assigned using a sealed-envelope draw to an experimental model or a control model. We randomly assigned 4 medical house staff teams (43 interns) using a 3-month crossover design to a 2003-compliant model of every fourth night overnight call (control) with 30-hour duty limits or to one of two 2011-compliant models of every fifth night overnight call (Q5) or a night float schedule (NF), both with 16-hour duty limits. We measured sleep duration using actigraphy and used admission volumes, educational opportunities, the number of handoffs, and satisfaction surveys to assess trainee education, continuity of patient care, and perceived quality of care. RESULTS The study included 560 control, 420 Q5, and 140 NF days that interns worked and 834 hospital admissions. Compared with controls, interns on NF slept longer during the on call period (mean, 5.1 vs 8.3 hours; P = .003), and interns on Q5 slept longer during the postcall period (mean, 7.5 vs 10.2 hours; P = .05). However, both the Q5 and NF models increased handoffs, decreased availability for teaching conferences, and reduced intern presence during daytime work hours. Residents and nurses in both experimental models perceived reduced quality of care, so much so with NF that it was terminated early. Compared with a 2003-compliant model, two 2011 duty hour regulation-compliant models were associated with increased sleep duration during the on-call period and with deteriorations in educational opportunities, continuity of patient care, and perceived quality of care.

A comparative study of entrepreneurs and managers: stress, burnout, locus of control, and social support.

This study investigated the relationships of job stress to job burnout, of locus of control and social support to stress and burnout, and the moderating effects of locus of control and social support on the stress-burnout relationship. These relationships were tested with questionnaire data collected from a random sample of entrepreneurs (N = 238) and managers (N = 288). Results showed that entrepreneurs reported that they had higher internal locus of control, received less social support, and had less job burnout than managers. Hierarchical regression analyses found support for eight of the ten main effects and one of the four moderating effects.

Poverty and Internalizing Symptoms: The Indirect Effect of Middle Childhood Poverty on Internalizing Symptoms via an Emotional Response Inhibition Pathway.

Childhood poverty is a pervasive problem that can alter mental health outcomes. Children from impoverished circumstances are more likely than their middle-income counterparts to develop internalizing problems such as depression and anxiety. To date, however, the emotional-cognitive control processes that link childhood poverty and internalizing symptoms remain largely unexplored. Using the Emotion Go/NoGo paradigm, we examined the association between poverty and emotional response inhibition in middle childhood. We further examined the role of emotional response inhibition in the link between middle childhood poverty and internalizing symptoms. Lower income was associated with emotional response inhibition difficulties (indexed by greater false alarm rates in the context of task irrelevant angry and sad faces). Furthermore, emotional response inhibition deficits in the context of angry and sad distracters were further associated with child-report internalizing problems. The results of the current study demonstrate the significance of understanding the emotional-cognitive control vulnerabilities of children raised in poverty and their association with mental health outcomes.

Internal Control, CPA Recognition and Performance Consequence: Evidence from Chinese Real Estate Enterprises

Zhang, Chuan; Zhang, Lili; Geng, Yi

In recent years, internal control has caught more and more attention over the whole globe. However, whether internal control could improve business efficiency also lacks the empirical supports. Based on a sample size of 146 Chinese real estate enterprises, this study analyses the CPA’s recognition degree on firm’s implementing internal control, and its performance consequence. The evidence suggests that CPAs are able to give exact evaluation on firm’s internal control implement, and the higher the internal control implemented, the better performance the enterprise will have.

Symptom-Based Controller Therapy: A New Paradigm for Asthma Management

PubMed Central

Divekar, Rohit; Ameredes, Bill T.; Calhoun, William J.

2013-01-01

Appropriate management of persistent asthma, according to US and international guidelines, requires daily use of controller medications, most generally, inhaled corticosteroids (ICS). This approach, although effective and well established, imposes burdens of treatment and side effects onto asthma patients. A growing body of evidence suggests that patients with persistent asthma need not be managed with daily ICS, but rather can use them on an intermittent basis, occasioned by the occurrence of symptoms sufficient to warrant treatment with a rescue inhaler. Large, randomized, controlled studies, over a range of asthma severity, and in a range of ages from pediatrics to adults, suggest that in well-selected patients, a symptom based approach to administering controller therapy may produce equivalent outcomes, while reducing exposure to ICS. The concept of providing anti-inflammatory treatment to the patient, at the time inflammation is developing, is termed ‘temporal personalization’. The evidence to date suggests that symptom-based controller therapy is broadly useful in selected asthma patients, and is a management approach that could be incorporated into US and international guidelines for asthma.

Effects of cavity size on the control of transonic internal flow around a biconvex circular arc airfoil

Rahman, M. Mostaqur; Hasan, A. B. M. Toufique; Rabbi, M. S.

2017-06-01

In transonic flow conditions, self-sustained shock wave oscillation on biconvex airfoils is initiated by the complex shock wave boundary layer interaction which is frequently observed in several modern internal aeronautical applications such as inturbine cascades, compressor blades, butterfly valves, fans, nozzles, diffusers and so on. Shock wave boundary layer interaction often generates serious problems such as unsteady boundary layer separation, self-excited shock waveoscillation with large pressure fluctuations, buffeting excitations, aeroacoustic noise, nonsynchronous vibration, high cycle fatigue failure and intense drag rise. Recently, the control of the self-excited shock oscillation around an airfoil using passive control techniques is getting intense interest. Among the passive means, control using open cavity has found promising. In this study, the effect of cavity size on the control of self-sustained shock oscillation was investigated numerically. The present computations are validated with available experimental results. The results showed that the average root mean square (RMS) of pressure oscillation around the airfoil with open cavity has reduced significantly when compared to airfoil without cavity (clean airfoil).

Postoperative recovery and complications were monitored. The time to wound healing was 12.96 ± 2.25 d in the treatment group shorter than 19.58 ± 2.71 d in the control group. Slight pain rate was 58.3% in the treatment group higher than 22.9% in the control group; moderate pain rate was 33.3% in the treatment group lower than 56.3% in the control group severe pain rate was 8.4% in the treatment group lower than 20.8% in the control group. No edema rate was 70.8% in the treatment group higher than 43.8% in the control group; mild local edema rate was 26% in the treatment group lower than 39.6% in the control group obvious local edema was 3.03% in the treatment group lower than 16.7% in the control group. No stenosis rate was 85.4% in the treatment group higher than 63.5% in the control group; moderate stenosis rate was 14.6% in the treatment group Lower than 27.1% in the control group severe anal stenosis rate was 0% in the treatment group lower than 9.4% in the control group. Milligan-Morgan hemorrhoidectomy with anal cushion suspension and partial internal sphincter resection is the optimal treatment for circumferential mixed hemorrhoids and can be widely applied in clinical settings.

Pivoting neuromuscular control and proprioceptive acuity may play an important role in anterior cruciate ligament injuries. The goal of this study was to investigate whether pivoting off-axis intensity adjustable neuromuscular control training (POINT) could improve pivoting neuromuscular control, proprioceptive acuity, and functional performance. Among 41 subjects, 21 subjects participated in 18 sessions of POINT (three sessions per week for 6 wk), and 20 subjects served as controls who did their regular workout. Both groups received pre-, mid-, and postintervention evaluations. Propensity score analysis with multivariable regression adjustment was used to investigate the effect of training on pivoting neuromuscular control (pivoting instability, leg pivoting stiffness, maximum internal, and external pivoting angles), proprioceptive acuity, and functional performance in both groups. Compared with the control group, the training group significantly improved pivoting neuromuscular control as reduced pivoting instability, reduced maximum internal and external pivoting angles, increased leg pivoting stiffness, and decreased entropy of time to peak EMG in the gluteus maximus and lateral gastrocnemius under pivoting perturbations. Furthermore, the training group enhanced weight-bearing proprioceptive acuity and improved the single leg hop distance. Improvement of pivoting neuromuscular control in functional weight-bearing activities and task performances after POINT may help develop lower limb injury prevention and rehabilitation methods to reduce anterior cruciate ligament and other musculoskeletal injuries associated with pivoting sports.

Summarizing the evidence on the international trade in illegal wildlife.

PubMed

Rosen, Gail Emilia; Smith, Katherine F

2010-08-01

The global trade in illegal wildlife is a multi-billion dollar industry that threatens biodiversity and acts as a potential avenue for invasive species and disease spread. Despite the broad-sweeping implications of illegal wildlife sales, scientists have yet to describe the scope and scale of the trade. Here, we provide the most thorough and current description of the illegal wildlife trade using 12 years of seizure records compiled by TRAFFIC, the wildlife trade monitoring network. These records comprise 967 seizures including massive quantities of ivory, tiger skins, live reptiles, and other endangered wildlife and wildlife products. Most seizures originate in Southeast Asia, a recently identified hotspot for future emerging infectious diseases. To date, regulation and enforcement have been insufficient to effectively control the global trade in illegal wildlife at national and international scales. Effective control will require a multi-pronged approach including community-scale education and empowering local people to value wildlife, coordinated international regulation, and a greater allocation of national resources to on-the-ground enforcement.

Emerging diseases and implications for global trade.

PubMed

Thiermann, A

2004-08-01

Emerging diseases could have a devastating impact on international trade unless there is a change in the traditional approach to disease control and new holistic prevention and control strategies are adopted. The impact that emerging diseases will have on international trade will depend on several factors, such as the nature of the pathogen, the degree of co-ordination and integration between Veterinary Services and Public Health authorities, the ability to rapidly detect and respond to a disease appearance, and the existing trade relationship between countries. Strategies to control emerging diseases will be more effective if competent authorities and veterinary infrastructures in particular, integrate their public and animal health objectives into a single strategy. The co-ordinating role of international standard setting organisations such as the World Organisation for Animal Health (OIE) will be crucial. This paper discusses the events contributing to the appearance and spread of new emerging diseases and examines the changing roles of Veterinary Services and international organisations. Reference is also made to measures that can be taken towards minimising potential trade disruptions caused by the appearance of an emerging disease.

The dorsal striatum and ventral striatum play different roles in the programming of social behaviour: a tribute to Lex Cools.

PubMed

van den Bos, Ruud

2015-02-01

Early work by Lex Cools suggested that the caudate nucleus (dorsal striatum) plays a role in programming social behaviour: enhanced activity in the caudate nucleus increased the extent to which ongoing behaviour is controlled by the individual's own behaviour (internal control) rather than by that of its partners (external control). Interestingly, later studies by others have indicated that the ventral striatum plays a role in external rather than internal control. Here, I discuss the role of these different striatal areas - and the emotional (ventral striatum) and cognitive control (dorsal striatum) system in which they are embedded - in the organization of social behaviour in the context of locus of control. Following on from this discussion, I will pay particular attention to individual differences in social behaviour (individuals with more internal or external control), focusing on the role of dopamine, serotonin and the effects of stress-related challenges in relation to their different position in a dominance hierarchy. I will subsequently allude to potential psychological and behavioural problems in the social domain following on from these differences in locus of control ['social obliviousness' (dorsal stratum) and 'social impulsivity' (ventral striatum)]. In doing so, I provide as a tribute a historical account of the early research by Lex Cools.

Control of atomic transition rates via laser-light shaping

NASA Astrophysics Data System (ADS)

Jáuregui, R.

2015-04-01

A modular systematic analysis of the feasibility of modifying atomic transition rates by tailoring the electromagnetic field of an external coherent light source is presented. The formalism considers both the center of mass and internal degrees of freedom of the atom, and all properties of the field: frequency, angular spectrum, and polarization. General features of recoil effects for internal forbidden transitions are discussed. A comparative analysis of different structured light sources is explicitly worked out. It includes spherical waves, Gaussian beams, Laguerre-Gaussian beams, and propagation invariant beams with closed analytical expressions. It is shown that increments in the order of magnitude of the transition rates for Gaussian and Laguerre-Gaussian beams, with respect to those obtained in the paraxial limit, require waists of the order of the wavelength, while propagation invariant modes may considerably enhance transition rates under more favorable conditions. For transitions that can be naturally described as modifications of the atomic angular momentum, this enhancement is maximal (within propagation invariant beams) for Bessel modes, Mathieu modes can be used to entangle the internal and center-of-mass involved states, and Weber beams suppress this kind of transition unless they have a significant component of odd modes. However, if a recoil effect of the transition with an adequate symmetry is allowed, the global transition rate (center of mass and internal motion) can also be enhanced using Weber modes. The global analysis presented reinforces the idea that a better control of the transitions between internal atomic states requires both a proper control of the available states of the atomic center of mass, and shaping of the background electromagnetic field.

Controlled carrier screening in p-n NiO/GaN piezoelectric generators by an Al2O3 insertion layer

2017-12-01

The performance of a piezoelectric generator (PG) depends significantly on the internal screening process inside the device. As piezoelectric charges appear on both ends of the piezoelectric crystal, internal screening starts to decrease the piezoelectric bias. Therefore, the piezoelectric energy generated by external stress is not fully utilized by external circuit, which is the most challenging aspect of high-efficiency PGs. In this work, the internal screening effect of a NiO/GaN p-n PG was analyzed and controlled with an Al2O3 insertion layer. Internal screening in the p-n diode PG was categorized into free-carrier screening in neutral regions and junction screening due to charge drift across the junction. It was observed that junction screening could be significantly suppressed by inserting an Al2O3 layer and that effect was dominant in a leaky diode PG. With this implementation, the piezoelectric bias of the NiO/GaN PG was improved by a factor of ~100 for high-leakage diodes and a factor of ~1.6 for low-leakage diodes. Consequently, NiO/Al2O3/GaN PGs under a stress of 5 MPa provided a piezoelectric bias of 12.1 V and a current density of 2.25 µA cm-2. The incorporation of a highly resistive Al2O3 layer between p-NiO and n-GaN layers in NiO/GaN heterojunctions provides an efficient means of improving the piezoelectric performance by controlling the internal screening of the piezoelectric field.

A review of effects in man of morphine-like drugs which have been brought under international narcotics control is presented in the form of individual monographs. These are based on controlled observations with quantitative data and significant reports of results obtained in medical practice. In a summarizing section, the drugs are compared with respect to effectiveness, side-effects and addiction liability. Morphine-like drugs of natural and synthetic origin now cover a wide range of potency (analgesic, antitussive), not necessarily paralleled by incidence of side-effects or addiction liability.

The control of invasive species on private property with neighbor-to-neighbor spillovers.

PubMed

Fenichel, Eli P; Richards, Timothy J; Shanafelt, David W

2014-10-01

Invasive pests cross property boundaries. Property managers may have private incentives to control invasive species despite not having sufficient incentive to fully internalize the external costs of their role in spreading the invasion. Each property manager has a right to future use of his own property, but his property may abut others' properties enabling spread of an invasive species. The incentives for a foresighted property manager to control invasive species have received little attention. We consider the efforts of a foresighted property manager who has rights to future use of a property and has the ability to engage in repeated, discrete control activities. We find that higher rates of dispersal, associated with proximity to neighboring properties, reduce the private incentives for control. Controlling species at one location provides incentives to control at a neighboring location. Control at neighboring locations are strategic complements and coupled with spatial heterogeneity lead to a weaker-link public good problem, in which each property owner is unable to fully appropriate the benefits of his own control activity. Future-use rights and private costs suggest that there is scope for a series of Coase-like exchanges to internalize much of the costs associated with species invasion. Pigouvian taxes on invasive species potentially have qualitatively perverse behavioral effects. A tax with a strong income effect (e.g, failure of effective revenue recycling) can reduce the value of property assets and diminish the incentive to manage insects on one's own property.

A tax with a strong income effect (e.g, failure of effective revenue recycling) can reduce the value of property assets and diminish the incentive to manage insects on one’s own property.

Filamentous mat-forming cyanobacteria are increasingly impairing uses of freshwater resources. To effectively manage, a better understanding of control measures is needed. Copper (Cu)-based algaecide formulations are often applied to reactively control nuisance cyanobacterial blooms. This laboratory research assessed typical field exposure scenarios for the ability of Cu to partition to, and accumulate in Lyngbya wollei. Exposure factors (Cu concentration × duration) of 4, 8, 16, 24, 32 h were tested across three aqueous Cu concentrations (1, 2, 4 ppm). Results indicated that internally accumulated copper correlated with control of L. wollei, independent of adsorbed copper. L. wollei control was determined by filament viability and chlorophyll a concentrations. Similar exposure factors elicited similar internalized copper levels and consequent responses of L. wollei. Ultimately, a "concentration-exposure-time" (CET) model was created to assist water resource managers in selecting an appropriate treatment regime for a specific in-water infestation. By assessing the exposure concentration and duration required to achieve the internal threshold of copper (i.e., critical burden) that elicits control, water management objectives can be achieved while simultaneously decreasing the environmental loading of copper and potential for non-target species risks.

Despite limited preparation and knowledge base, surgical interns have important teaching responsibilities. Nevertheless, few faculty development programs are aimed at interns. Succinct teaching skill content was electronically distributed over time (spaced education) to interns in academic year 2010/2011. The interns in the previous year served as historic controls. Electronic surveys were distributed for program evaluation. Fifteen of 24 (62.5%) interns and 35 of 49 (71.4%) students responded to the surveys in academic year 2009/2010 and 16 of 27 (59.3%) interns and 38 of 52 (73%) students responded in academic year 2010/2011. Surveys showed improved attitudes toward teaching by interns as well as a higher estimation of interns' teaching skills as rated by students for those interns who received the spaced education program. Using spaced education to improve interns' teaching skills is a potentially powerful intervention that improves interns' enthusiasm for teaching and teaching effectiveness. The changes are mirrored in students' ratings of interns' teaching skills and interns' attitudes toward teaching. Copyright © 2013 Elsevier Inc. All rights reserved.

Mentoring SFRM: A New Approach to International Space Station Flight Control Training

NASA Technical Reports Server (NTRS)

Huning, Therese; Barshi, Immanuel; Schmidt, Lacey

2009-01-01

The Mission Operations Directorate (MOD) of the Johnson Space Center is responsible for providing continuous operations support for the International Space Station (ISS). Operations support requires flight controllers who are skilled in team performance as well as the technical operations of the ISS. Space Flight Resource Management (SFRM), a NASA adapted variant of Crew Resource Management (CRM), is the competency model used in the MOD. ISS flight controller certification has evolved to include a balanced focus on development of SFRM and technical expertise. The latest challenge the MOD faces is how to certify an ISS flight controller (Operator) to a basic level of effectiveness in 1 year. SFRM training uses a twopronged approach to expediting operator certification: 1) imbed SFRM skills training into all Operator technical training and 2) use senior flight controllers as mentors. This paper focuses on how the MOD uses senior flight controllers as mentors to train SFRM skills.

Nonlinear model predictive control for chemical looping process

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

Joshi, Abhinaya; Lei, Hao; Lou, Xinsheng

A control system for optimizing a chemical looping ("CL") plant includes a reduced order mathematical model ("ROM") that is designed by eliminating mathematical terms that have minimal effect on the outcome. A non-linear optimizer provides various inputs to the ROM and monitors the outputs to determine the optimum inputs that are then provided to the CL plant. An estimator estimates the values of various internal state variables of the CL plant. The system has one structure adapted to control a CL plant that only provides pressure measurements in the CL loops A and B, a second structure adapted to amore » CL plant that provides pressure measurements and solid levels in both loops A, and B, and a third structure adapted to control a CL plant that provides full information on internal state variables. A final structure provides a neural network NMPC controller to control operation of loops A and B.« less

Emerging Trends in International Law Concerning Global Infectious Disease Control1

PubMed Central

2003-01-01

International cooperation has become critical in controlling infectious diseases. In this article, I examine emerging trends in international law concerning global infectious disease control. The role of international law in horizontal and vertical governance responses to infectious disease control is conceptualized; the historical development of international law regarding infectious diseases is described; and important shifts in how states, international institutions, and nonstate organizations use international law in the context of infectious disease control today are analyzed. The growing importance of international trade law and the development of global governance mechanisms, most prominently in connection with increasing access to drugs and other medicines in unindustrialized countries, are emphasized. Traditional international legal approaches to infectious disease control—embodied in the International Health Regulations—may be moribund. PMID:12643821

Thinking about muscles: the neuromuscular effects of attentional focus on accuracy and fatigue.

PubMed

Lohse, Keith R; Sherwood, David E

2012-07-01

Although the effects of attention on movement execution are well documented behaviorally, much less research has been done on the neurophysiological changes that underlie attentional focus effects. This study presents two experiments exploring effects of attention during an isometric plantar-flexion task using surface electromyography (sEMG). Participants' attention was directed either externally (towards the force plate they were pushing against) or internally (towards their own leg, specifically the agonist muscle). Experiment 1 tested the effects of attention on accuracy and efficiency of force produced at three target forces (30, 60, and 100% of the maximum voluntary contraction; MVC). An internal focus of attention reduced the accuracy of force being produced and increased cocontraction of the antagonist muscle. Error on a given trial was positively correlated with the magnitude of cocontraction on that trial. Experiment 2 tested the effects of attention on muscular fatigue at 30, 60 and 100%MVC. An internal focus of attention led to less efficient intermuscular coordination, especially early in the contraction. These results suggest that an internal focus of attention disrupts efficient motor control in force production resulting in increased cocontraction, which potentially explains other neuromechanical findings (e.g. reduced functional variability with an internal focus).

A new approach for an internally controlled PCR was developed using a custom-synthesized oligonucleotide as the internal control. Three different PCR setups demonstrated the usefulness of this approach: (i) the addition of the respective internal control to samples containing ssDNA virus Parvo B19; (ii) the co-extraction of plasma samples and the respective internal control for the detection of the ssDNA virus TTV; and (iii) the addition of the respective internal control to a crude lysate of tail pieces for the genotyping of FVIII knockout mice, demonstrating that this approach is also applicable for dsDNA.

Case-Control Studies of Sporadic Enteric Infections: A Review and Discussion of Studies Conducted Internationally from 1990 to 2009

Epidemiologists have used case-control studies to investigate enteric disease outbreaks for many decades. Increasingly, case-control studies are also used to investigate risk factors for sporadic (not outbreak-associated) disease. While the same basic approach is used, there are important differences between outbreak and sporadic disease settings that need to be considered in the design and implementation of the case-control study for sporadic disease. Through the International Collaboration on Enteric Disease “Burden of Illness” Studies (the International Collaboration), we reviewed 79 case-control studies of sporadic enteric infections caused by nine pathogens that were conducted in 22 countries and published from 1990 through to 2009. We highlight important methodological and study design issues (including case definition, control selection, and exposure assessment) and discuss how approaches to the study of sporadic enteric disease have changed over the last 20 years (e.g., making use of more sensitive case definitions, databases of controls, and computer-assisted interviewing). As our understanding of sporadic enteric infections grows, methods and topics for case-control studies are expected to continue to evolve; for example, advances in understanding of the role of immunity can be used to improve control selection, the apparent protective effects of certain foods can be further explored, and case-control studies can be used to provide population-based measures of the burden of disease.

Efficacy of 1-methylcyclopropene on the mitigation of storage disorders of "Rocha" pear under normal refrigerated and controlled atmospheres.

PubMed

Almeida, Domingos Pf; Carvalho, Rita; Dupille, Eve

2016-07-01

Alternatives are needed for long-term preservation of European pears (Pyrus communis L.) after the ban on diphenylamine. "Rocha" pear fruit harvested at commercial maturity were treated with 1-methylcyclopropene (1-methylcyclopropene, SmartFresh™) and diphenylamine and stored at 0 ℃, 90-95% relative humidity, under normal atmosphere for up to six months or under controlled atmosphere (controlled atmosphere, 3 kPa O2 + 0.7 kPa CO2) for up to 9.4 months. At 312 nl l(-1), 1-methylcyclopropene reduced softening and yellowing, and increased soluble solids content during shelf life in comparison with fruit treated with diphenylamine. 1-Methylcyclopropene at 312 nl l(-1) was also more effective than diphenylamine in reducing superficial scald and internal browning disorders. 1-Methylcyclopropene at 150 nl l(-1) had little effect on ripening-related changes but was effective against physiological disorders of pears stored in regular atmosphere or under controlled atmosphere. Delayed controlled atmosphere slightly reduced internal browning disorders but increased superficial scald. 1-Methylcyclopropene at 312 nl l(-1) reduced physiological disorders in "Rocha" pear under refrigerated storage and delayed ripening-related softening and color changes during shelf life. At 150 nl l(-1), 1-methylcyclopropene is as effective as diphenylamine against storage disorders without ripening impairment. © The Author(s) 2015.

Social withdrawal in early childhood is a risk factor for later socioemotional difficulties. This study examined the joint effects of children's social withdrawal and mothers' and fathers' parenting styles on children's socioemotional development. Based on diatheses-stress, vantage sensitivity, and differential susceptibility models, socially withdrawn children were assumed to be more prone to parental influences than others. Teachers rated 314 children on prosocial skills, and internalizing and externalizing behaviors at three points in time between grades 1-3. Mothers (n = 279) and fathers (n = 182) filled in questionnaires measuring their affection, and their behavioral and psychological control at the same points in time. Teacher reports on children's level of social withdrawal were obtained at the end of kindergarten. Panel analysis showed that particularly those children who showed signs of social withdrawal were vulnerable to the negative effects of low maternal affection in terms of externalizing behavior. Moreover, among these children, mothers' and fathers' psychological control predicted high levels of internalizing problem but, at the same time, mothers' psychological control predicted also a high level of prosocial behavior and low levels of externalizing problem. The results supported the diathesis-stress model more than the differential susceptibility model. For example, socially withdrawn children were found to be particularly vulnerable to the negative effects of low maternal affection. Although maternal psychological control had positive effects on the prosocial skills of socially withdrawn children, and reduced the amount of externalizing problems, it was at the same time associated with an increase in their internalizing problems. In this way, socially withdrawn children seem to be at risk of pleasing their mothers at the cost of their own well-being. © 2014 The Authors.

2014-01-01

Purpose Pivoting neuromuscular control and proprioceptive acuity may play an important role in ACL injuries. The goal of this study was to investigate whether pivoting neuromuscular training on an offaxis elliptical trainer (POINT) could improve pivoting neuromuscular control, proprioceptive acuity, and functional performance. Methods Among 41 subjects, 21 subjects participated in 18 sessions of POINT (3 sessions/week for 6 weeks), and 20 subjects served as controls who did their regular workout. Both groups received pre-, mid-, and post-intervention evaluations. Propensity score analysis with multivariable regression adjustment was used to investigate the effect of training on pivoting neuromuscular control (pivoting instability, leg pivoting stiffness, maximum internal and external pivoting angles), proprioceptive acuity, and functional performance in both groups. Results Compared to the control group, the training group significantly improved pivoting neuromuscular control as reduced pivoting instability, reduced maximum internal and external pivoting angles, increased leg pivoting stiffness, and decreased entropy of time to peak EMG in the gluteus maximus and lateral gastrocnemius under pivoting perturbations. Furthermore, the training group enhanced weight-bearing proprioceptive acuity and improved the single leg hop distance. Conclusion Improvement of pivoting neuromuscular control in functional weight-bearing activities and task performances following POINT may help develop lower limb injury prevention and rehabilitation methods to reduce ACL and other musculoskeletal injuries associated with pivoting sports.

To evaluate the efficacy of flow control of the internal carotid artery (ICA) by the clamping of the common carotid artery, external carotid artery, and superior thyroid artery during surgical ICA dissection to reduce ischemic complications after carotid endarterectomy (CEA). Sixty-seven patients (59 men; age, 70.5 ± 6.2 years) who underwent CEA by the same surgeon were retrospectively studied. Both conventional CEA (n = 29) and flow-control CEA (n = 38) were performed with the patient under general anesthesia and with the use of somatosensory-evoked potential and near-infrared spectroscopy monitoring as a guide for selective shunting. The number of new postoperative infarcts was assessed with preoperative and postoperative diffusion-weighted images (DWIs) obtained within 3 days of surgery. In addition to surgical technique, the effects of the following factors on new infarcts also were examined: age, side of ICA stenosis, high-grade stenosis, symptoms, and application of shunting. New postoperative DWI lesions were observed in 7 of 67 patients (10.4%), and none of them was symptomatic. With respect to operative technique, the incidence rate of DWI spots was significantly lower in the flow-control group (2.6%) than in the conventional group (20.7%), odds ratio: 0.069; 95% confidence interval: 0.006-0.779; P = 0.031). On multiple logistic regression analysis, age, side of ICA stenosis, high-grade stenosis, symptoms, and the use of internal shunting did not have significant effects on new postoperative DWI lesions, whereas technique did have an effect. The proximal flow-control technique for CEA helps avoid embolic complications during surgical ICA dissection. Copyright © 2014 Elsevier Inc. All rights reserved.

Drew, Christa A; Clydesdale, Fergus M

2015-01-01

The demand for safety in the US food supply from production to consumption necessitates a scientific, risk-based strategy for the management of microbiological, chemical, and physical hazards in food. The key to successful management is an increase in systematic collaboration and communication and in enforceable procedures with all domestic and international stakeholders. The enactment of the Food Safety Modernization Act (FSMA) aims to prevent or reduce large-scale food-borne illness outbreaks through stricter facility registration and records standards, mandatory prevention-based controls, increased facility inspections in the United States and internationally, mandatory recall authority, import controls, and increased consumer communication. The bill provisions are expected to cost $1.4 billion over the next four years. Effective implementation of the FSMA's 50 rules, reports, studies, and guidance documents in addition to an increased inspection burden requires further funding appropriations. Additional full-time inspectors and unprecedented foreign compliance is necessary for the full and effective implementation of the FSMA.

Cheng, Yangjian; Niu, Jianjun; Zhang, Yongyou; Huang, Jianwei; Li, Qingge

2006-10-01

Armored RNA has been increasingly used as both an external and internal positive control in nucleic acid-based assays for RNA virus. In order to facilitate armored RNA purification, a His6 tag was introduced into the loop region of the MS2 coat protein, which allows the exposure of multiple His tags on the surface during armored RNA assembly. The His-tagged armored RNA particles were purified to homogeneity and verified to be free of DNA contamination in a single run of affinity chromatography. A fragment of severe acute respiratory syndrome coronavirus (SARS-CoV) genome targeted for SARS-CoV detection was chosen for an external positive control preparation. A plant-specific gene sequence was chosen for a universal noncompetitive internal positive control preparation. Both controls were purified by Co2+ affinity chromatography and were included in a real-time reverse transcription-PCR assay for SARS-CoV. The noncompetitive internal positive control can be added to clinical samples before RNA extraction and enables the identification of potential inhibitive effects without interfering with target amplification. The external control could be used for the quantification of viral loads in clinical samples.

Cultural Challenges Faced by American Mission Control Personnel Working with International Partners

Clement, J. L.; Ritsher, J. B.

2006-01-01

Operating the International Space Station (ISS) involves an indefinite, continuous series of long-duration international missions, and this requires an unprecedented degree of cooperation across multiple sites, organizations, and nations. Both junior and senior mission control personnel have had to find ways to address the cultural challenges inherent in such work, but neither have had systematic training in how to do so. The goals of this study were to identify and evaluate the major cultural challenges faced by ISS mission control personnel and to highlight the approaches that they have found most effective to surmount these challenges. We pay particular attention to the approaches successfully employed by the senior personnel and the training needs identified by the junior personnel. We also evaluate the extent to which the identified approaches and needs are consistent across the two samples. METHODS: Participants included a sample of 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers. All participants were mission operations specialists chosen on the basis of having worked extensively with international partners. Data were collected using a semi-structured qualitative interview and content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. RESULTS: The senior respondents had substantial consensus on several cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Data from the junior respondents will be presented for the first time at the meeting. DISCUSSION: Although specific to American ISS personnel, our results are consistent with recent management, cultural, and aerospace research on other populations. We aim to use our results to improve training for current and future mission control personnel working in international or multicultural mission operations teams.

Character of the opposition effect and negative polarization

NASA Technical Reports Server (NTRS)

Pieters, Carle M.; Shkuratov, Yu. G.; Stankevich, D. G.

1991-01-01

Photometric and polarimetric properties at small phase angles were measured for silicates with controlled surface properties in order to distinguish properties that are associated with surface reflection from those that are associated with multiple scattering from internal grain boundaries. These data provide insight into the causes and conditions of photometric properties observed at small phase angles for dark bodies of the solar system. Obsidian was chosen to represent a silicate dielectric with no internal scattering boundaries. Because obsidian is free of internal scatterers, light reflected from both the rough and smooth obsidian samples is almost entirely single and multiple Fresnel reflections form surface facets with no body component. Surface structure alone cannot produce an opposition effect. Comparison of the obsidian and basalt results indicates that for an opposition effect to occur, surface texture must be both rough and contain internal scattering interfaces. Although the negative polarization observed for the obsidian samples indicates single and multiple reflections are part of negative polarization, the longer inversion angle of the multigrain inversion samples implies that internal reflections must also contribute a significant negative polarization component.

A cadaver study was conducted to investigate the effects of triggering conditions (trigger grip span, contact location, and internal tendon force) on index finger triggering force and the force efficiency of involved tendons. Eight right human cadaveric hands were employed, and a motion simulator was built to secure and control the specimens. Index finger triggering forces were investigated as a function of different internal tendon forces (flexor digitorum profundus + flexor digitorum superficialis = 40, 70, and 100 N), trigger grip spans (40, 50, and 60 mm), and contact locations between the index finger and a trigger. Triggering forces significantly increased when internal tendon forces increased from 40 to 100 N. Also, trigger grip spans and contact locations had significant effects on triggering forces; maximum triggering forces were found at a 50 mm span and the most proximal contact location. The results revealed that only 10-30% of internal tendon forces were converted to their external triggering forces. Copyright © 2017 Elsevier Ltd. All rights reserved.

Crucial to the success of the proposed Framework Convention on Tobacco Control will be an understanding of the political and economic context for tobacco control policies, particularly in low-income and middle-income countries. Policy studies in Thailand and Zimbabwe employed the analytical perspective of political economy and a research strategy that used political mapping, a technique for characterizing and evaluating the political environment surrounding a policy issue, and stakeholder analysis, which seeks to identify key actors and to determine their capacity to shape policy outcomes. These policy studies clearly revealed how tobacco control in low-income and middle-income countries is also being shaped by developments in the global and regional political economy. Hence efforts to strengthen national control policies need to be set within the context of globalization and the international context. Besides the transnational tobacco companies, international tobacco groups and foreign governments, international agencies and nongovernmental organizations are also playing influential roles. It cannot be assumed, therefore, that the tobacco control strategies being implemented in industrialized countries will be just as effective and appropriate when implemented in developing countries. There is an urgent need to expand the number of such tobacco policy studies, particularly in low-income and middle-income countries. Comprehensive guidelines for tobacco policy analysis and research are required to support this process, as is a broader international strategy to coordinate further tobacco policy research studies at country, regional and global levels.

In a previous study of fragmentation patterns of (Ar)+3 clusters [G. Delgado-Barrio, S. Miret-Artés, P. Villarreal, and F. A. Gianturco, Z. Phys. D 27, 354 (1993)] it was found that overall rotations control the lifetimes of the occupied metastable states of the cluster and that a spherical, effective interaction was sufficient to describe the dynamical process. In the present study, the strong anisotropy of a more realistic three-particle interaction is introduced and its effects on metastable decay are examined. By separating internal rotations from internal vibrations of the diatomic ion, it is possible to show that internal predissociation pathways are very efficient and lead to very short lifetimes. The latter can be lengthened only when overall rotational states are directly included, thus confirming the physical picture of the earlier work.

Dynamic response of a Mach 2.5 axisymmetric inlet and turbojet engine with a poppet-value controlled inlet stability bypass system when subjected to internal and external airflow transients

NASA Technical Reports Server (NTRS)

Sanders, B. W.

1980-01-01

The throat of a Mach 2.5 inlet that was attached to a turbojet engine was fitted with a poppet-valve-controlled stability bypass system that was designed to provide a large, stable airflow range. Propulsion system response and stability bypass performance were determined for several transient airflow disturbances, both internal and external. Internal airflow disturbances included reductions in overboard bypass airflow, power lever angle, and primary-nozzle area as well as compressor stall. For reference, data are also included for a conventional, fixed-exit bleed system. The poppet valves greatly increased inlet stability and had no adverse effects on propulsion system performance. Limited unstarted-inlet bleed performance data are presented.

Artist's Concept of International Space Station (ISS)

Pictured is an artist's concept of the International Space Station (ISS) with solar panels fully deployed. In addition to the use of solar energy, the ISS will employ at least three types of propulsive support systems for its operation. The first type is to reboost the Station to correct orbital altitude to offset the effects of atmospheric and other drag forces. The second function is to maneuver the ISS to avoid collision with oribting bodies (space junk). The third is for attitude control to position the Station in the proper attitude for various experiments, temperature control, reboost, etc. The ISS, a gateway to permanent human presence in space, is a multidisciplinary laboratory, technology test bed, and observatory that will provide an unprecedented undertaking in scientific, technological, and international experimentation by cooperation of sixteen countries.

From infancy we learn to comply with societal norms. However, overt compliance is not necessarily accompanied by a change in internal beliefs. The neuromodulatory processes underlying these different phenomena are not yet understood. Here, we test the role of oxytocin in controlling overt compliance versus internalization of information delivered by a social source. After intranasal oxytocin administration, participants showed enhanced compliance to the erroneous opinion of others. However, this expression was coupled with a decrease in the influence of others on long-term memories. Our data suggest that this dissociation may result from reduced conflict in the face of social pressure, which increases immediate conforming behavior, but reduces processing required for deep encoding. These findings reveal a neurobiological control system that oppositely affects internalization and overt compliance.

International challenges and public policy issues.

PubMed

Morris, N

1999-01-01

The paper presents an overview of current public policy issues relating to biological standardisation and control, drawing on the extensive background material assembled for two recent international reviews, and previously published work. It identifies a number of factors which are destabilising the current system and promoting a climate for change. These include the squeeze on public sector resources, the growth in volume and complexity of biologicals, developing world needs, concerns about harmonisation and new social and ethical issues. It is argued that this situation presents important opportunities for reviewing the existing boundaries between regulatory scientists, industry, and the public, for international agreement on priorities and for harmonisation and mutual recognition. While considerable progress has already been made on these issues at national, regional and global level, there is a need for fuller international participation and the additional impetus that would come from a higher-profile commitment by governments. Such commitment will also be important for the vital questions of sustaining the scientific base and securing the resource for an effective, truly worldwide programme of standardisation and control. An international approach will also be essential in steering biologicals control through the difficult social and ethical questions of the future. WHO, in collaboration with national authorities, has a key role to play in these developments.

RT-qPCR requires a suitable set of internal control genes (ICGs) for an accurate normalization. The usefulness of 7 previously published ICGs in the human placenta was analyzed according to the effects of betamethasone treatment, sex and fetal age. Raw RT-qPCR data of the ICGs were evaluated using published algorithms. The algorithms revealed that a reliable normalization was achieved using the geometrical mean of PPIA, RPL19, HMBS and SDHA. The use of a different subset ICGs out of the 7 investigated, although not statistically affected by the conditions, biased the results, as demonstrated through changes in expression of glucocorticoid receptor (NR3C1) mRNA as a target gene.

This study investigates the relation between parental verbal punishment and externalizing and internalizing behavior problems in Filipino children, and the moderating role of parental warmth in this relation, for same-sex (mothers-girls; fathers-boys) and cross-sex parent-child groups (mothers-boys; fathers-girls). Measures used were the Rohner Parental Acceptance-Rejection and Control Scale (PARQ/Control), the Achenbach Child Behavior Checklist (CBC), and a discipline measure (DI) constructed for the study. Participants were 117 mothers and 98 fathers of 61 boys and 59 girls who responded to a discipline interview, the Parental Acceptance-Rejection and Control scale (PARQ/Control) and the Achenbach Child Behavior Checklist via oral interviews. Hierarchical multiple regression analyses (with Bonferroni-corrected alpha levels) revealed that maternal frequency of verbal punishment was positively related to internalizing and externalizing outcomes in boys and girls whereas paternal frequency of verbal punishment was positively related to girls’ externalizing behavior. Significant interactions between verbal punishment and maternal warmth in mother-girl groups were also found for both internalizing and externalizing behaviors. While higher maternal warmth ameliorated the impact of low verbal punishment on girls’ internalizing and externalizing behaviors, it exacerbated the effect of high verbal punishment on negative outcomes.

Few studies have investigated if mother's interest and father's interest in child's education are linked to educational attainment via their impact on child's self-esteem and locus of control. (1) To investigate (after controlling for known confounding factors) the long-term effect of mother's and father's interest in child's education at age 10 and child's locus of control and self-esteem at age 10 in educational attainment at age 26; and (2) to explore if mother's interest and father's interest in child's education are linked to child's educational attainment via their effect in increasing child's self-esteem and internal locus of control. The study used longitudinal data from sweeps of the 1970 British Cohort Study (BCS70). The initial sample was those 1,737 men and 2,033 women with valid data on age 10 self-esteem, locus of control, father's interest, mother's interest, and age 26 educational attainment. Of these, 1,326 men and 1,578 women were included in the final analysis. The birth to age 10 factors that were controlled for were birth weight, parental social class, socio-economic disadvantage, emotional/behavioural problems, cognitive ability, and mother's educational attainment. At the multivariate level, internal locus of control and mother's interest (but not self-esteem) were significantly related to educational attainment in both men and women. Father's interest was a significant predictor of educational attainment only in women. Parent's interest was not linked to educational attainment via its impact on child's self-esteem or locus of control. Self-esteem predicted educational attainment in both genders by increasing internal locus of control, and fathers' interest predicted educational attainment in men by increasing mother's involvement. Although mothers' and fathers' interest in their children's education were not linked to educational attainment via their impact on children's self-esteem or locus of control, they were significant predictors of educational attainment especially in daughters.

Controlling Pandemic Flu: The Value of International Air Travel Restrictions

Background Planning for a possible influenza pandemic is an extremely high priority, as social and economic effects of an unmitigated pandemic would be devastating. Mathematical models can be used to explore different scenarios and provide insight into potential costs, benefits, and effectiveness of prevention and control strategies under consideration. Methods and Findings A stochastic, equation-based epidemic model is used to study global transmission of pandemic flu, including the effects of travel restrictions and vaccination. Economic costs of intervention are also considered. The distribution of First Passage Times (FPT) to the United States and the numbers of infected persons in metropolitan areas worldwide are studied assuming various times and locations of the initial outbreak. International air travel restrictions alone provide a small delay in FPT to the U.S. When other containment measures are applied at the source in conjunction with travel restrictions, delays could be much longer. If in addition, control measures are instituted worldwide, there is a significant reduction in cases worldwide and specifically in the U.S. However, if travel restrictions are not combined with other measures, local epidemic severity may increase, because restriction-induced delays can push local outbreaks into high epidemic season. The per annum cost to the U.S. economy of international and major domestic air passenger travel restrictions is minimal: on the order of 0.8% of Gross National Product. Conclusions International air travel restrictions may provide a small but important delay in the spread of a pandemic, especially if other disease control measures are implemented during the afforded time. However, if other measures are not instituted, delays may worsen regional epidemics by pushing the outbreak into high epidemic season. This important interaction between policy and seasonality is only evident with a global-scale model. Since the benefit of travel restrictions can be substantial while their costs are minimal, dismissal of travel restrictions as an aid in dealing with a global pandemic seems premature. PMID:17476323

Effects of a dynamic core stability program on the biomechanics of cutting maneuvers: A randomized controlled trial.

PubMed

Whyte, E F; Richter, C; O'Connor, S; Moran, K A

2018-02-01

Deficits in trunk control predict ACL injuries which frequently occur during high-risk activities such as cutting. However, no existing trunk control/core stability program has been found to positively affect trunk kinematics during cutting activities. This study investigated the effectiveness of a 6-week dynamic core stability program (DCS) on the biomechanics of anticipated and unanticipated side and crossover cutting maneuvers. Thirty-one male, varsity footballers participated in this randomized controlled trial. Three-dimensional trunk and lower limb biomechanics were captured in a motion analysis laboratory during the weight acceptance phase of anticipated and unanticipated side and crossover cutting maneuvers at baseline and 6-week follow-up. The DCS group performed a DCS program three times weekly for 6 weeks in a university rehabilitation room. Both the DCS and control groups concurrently completed their regular practice and match play. Statistical parametric mapping and repeated measures analysis of variance were used to determine any group (DCS vs control) by time (pre vs post) interactions. The DCS resulted in greater internal hip extensor (P=.017, η 2 =0.079), smaller internal knee valgus (P=.026, η 2 =0.076), and smaller internal knee external rotator moments (P=.041, η 2 =0.066) during anticipated side cutting compared with the control group. It also led to reduced posterior ground reaction forces for all cutting activities (P=.015-.030, η 2 =0.074-0.105). A 6-week DCS program did not affect trunk kinematics, but it did reduce a small number of biomechanical risk factors for ACL injury, predominantly during anticipated side cutting. A DCS program could play a role in multimodal ACL injury prevention programs. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Studies selected had randomized controlled trial (RCT), pretest–posttest with a non-randomized control group, or pretest–posttest one group study designs in which HIV-related interventions were being evaluated, and in which HIV/AIDS stigma was one of the outcomes being measured. A checklist was used to extract data from accepted studies, assess their internal validity, and overall quality. Data were extracted from 19 studies, and 14 of these studies demonstrated effectiveness in reducing HIV/ AIDS stigma. Only 2 of these 14 effective studies were considered good studies, based on quality, the extent to which the intervention focused on reducing HIV/AIDS stigma, and the statistics reported to demonstrate effectiveness. Future studies to reduce HIV/AIDS stigma could improve by designing interventions that pay greater attention to internal validity, use validated HIV/AIDS stigma instruments, and achieve both statistical and public health significance.

The aim of the study was to analyze the treatment effect of transumbilical single-port laparoscopic varicocelectomy (TUSPLV) on recurrent varicocele (VC). In order to compare the surgical effects of TUSPLV to traditional retroperitoneal ligation of the internal spermatic vein, 64 patients with recurrent VC were enrolled and divided into the control group (n=30) and the observation group (n=34). Patients in the control group underwent surgery using traditional retroperitoneal ligation of the internal spermatic vein, while those in the observation group underwent surgery using TUSPLV. The results showed that the time of operation and bleeding volume in the observation group were significantly lower. The occurrence and recurrence rates of periprocedural complications were considerably lower in the observation group. Differences were statistically significant (P<0.05). In terms of the pregnancy rate, the difference between the 2 groups had no statistical significance (P>0.05). We concluded that employing TUSPLV to treat recurrent VC was safe and effective.

To study the feasibility and acceptability of using video Internet communication to teach and evaluate surgical skills in a low-resource setting. This case-controlled study used video Internet communication for surgical skills teaching and evaluation. We randomized intern physicians rotating in the Obstetrics and Gynecology Department at Mulago Hospital at Makerere University in Kampala, Uganda, to the control arm (usual practice) or intervention arm (three video teaching sessions with University of California, San Francisco faculty). We made preintervention and postintervention videos of all interns tying knots using a small video camera and uploaded the files to a file hosting service that offers cloud storage. A blinded faculty member graded all of the videos. Both groups completed a survey at the end of the study. We randomized 18 interns with complete data for eight in the intervention group and seven in the control group. We found score improvement of 50% or more in six of eight (75%) interns in the intervention group compared with one of seven (14%) in the control group (P=.04). Scores declined in five of the seven (71%) controls but in none in the intervention group. Both intervention and control groups used attendings, colleagues, and the Internet as sources for learning about knot-tying. The control group was less likely to practice knot-tying than the intervention group. The trainees and the instructors felt this method of training was enjoyable and helpful. Remote teaching in low-resource settings, where faculty time is limited and access to visiting faculty is sporadic, is feasible, effective, and well-accepted by both learner and teacher. II.

Sediment dredging is an effective restoration method to control the internal phosphorus (P) loading of eutrophic lakes. However, the core question is that the real mechanism of dredging responsible for sediment internal P release still remains unclear. In this study, we investigated the P exchange across the sediment-water interface (SWI) and the internal P resupply ability from the sediments after dredging. The study is based on a one-year field simulation study in Lake Taihu, China, using a Rhizon soil moisture sampler, high-resolution dialysis (HR-Peeper), ZrO-Chelex diffusive gradients in thin film (ZrO-Chelex DGT), and P fractionation and adsorption isotherm techniques. The results showed low concentration of labile P in the pore water with a low diffusion potential and a low resupply ability from the sediments after dredging. The calculated flux of P from the post-dredged sediments decreased by 58% compared with that of non-dredged sediments. Furthermore, the resupply in the upper 20mm of the post-dredged sediments was reduced significantly after dredging (P<0.001). Phosphorus fractionation analysis showed a reduction of 25% in the mobile P fractions in the post-dredged sediments. Further analysis demonstrated that the zero equilibrium P concentration (EPC 0 ), partitioning coefficient (K p ), and adsorption capacity (Q max ) on the surface sediments increased after dredging. Therefore, dredging could effectively reduce the internal P resupply ability of the sediments. The reasons for this reduction are probably the lower contributions of mobile P fractions, higher retention ability, and the adsorption capacity of P for post-dredged sediments. Overall, this investigation indicated that dredging was capable of effectively controlling sediment internal P release, which could be ascribed to the removal of the surface sediments enriched with total phosphorus (TP) and/or organic matter (OM), coupled with the inactivation of P to iron (Fe) (hydr)oxides in the upper 20mm active layer.

In recent years, because of the air-spring control technique is more mature, that air- spring suspension systems already can be used to replace the classical vehicle suspension system. Depend on internal pressure variation of the air-spring, thestiffnessand the damping factor can be adjusted. Because of air-spring has highly nonlinear characteristic, therefore it isn’t easy to construct the classical controller to control the air-spring effectively. The paper based on Artificial Neural Network to propose a feasible control strategy. By using offline way for the neural network design and learning to the air-spring in different initial pressures and different loads, offline method through, predict air-spring stiffness parameter to establish a model. Finally, through adjusting air-spring internal pressure to change the K-parameter of the air-spring, realize the well dynamic control performance of air-spring suspension.

Purpose . Effectiveness of nonpharmacological multicomponent prevention delivered by trained volunteers (medical and psychology students), targeted at delirium risk factors in geriatric inpatients, was assessed at an internal medicine ward in Poland. Patients and Methods . Participants were recruited to intervention and control groups at the internal medicine ward (inclusion criteria: age ≥ 75, acute medical condition, basic orientation, and logical contact on admission; exclusion criteria: life expectancy < 24 hours, surgical hospitalization, isolation due to infectious disease, and discharge to other medical wards). Every day trained volunteers delivered a multicomponent standardized intervention targeted at risk factors of in-hospital complications to the intervention group. The control group, selected using a retrospective individual matching strategy (1 : 1 ratio, regarding age, gender, and time of hospitalization), received standard care. Outcome Measures. Hospitalization time, deaths, falls, delirium episodes, and antipsychotic prescriptions were assessed retrospectively from medical documentation. Results . 130 patients (38.4% males) participated in the study, with 65 in the intervention group. Antipsychotic medications were initiated less frequently in the intervention group compared to the control group. There was a trend towards a shorter hospitalization time and a not statistically significant decrease in deaths in the intervention group. Conclusion . Nonpharmacological multicomponent intervention targeted at delirium risk factors effectively reduced length of hospitalization and need for initiating antipsychotic treatment in elderly patients at the internal medicine ward.

Post-operative pancreatic fistula (POPF) is one of the most common causes of death following pancreaticoduodenectomy (PD). The aim of this study was to evaluate the clinical effect of a long-internal stent on the development of POPF in patients with a main pancreatic duct diameter of 3 mm or less. Patients (N = 108) with a main pancreatic duct (≤3 mm) who underwent PD were included in this single-institution historical control study. Between January 2012 and December 2013, 54 patients had undergone PJ with a long-internal stent across the duct-to-mucosa anastomosis (long-stent group), and between February 2009 and December 2011, 54 patients had undergone PJ without a stent (control). There was no significant difference between groups (long-stent vs control) in the incidence of POPF (70% vs. 56%, p = 0.110) and grade B/C POPF (26% vs. 26%, p = 1.000). Univariate analysis identified body mass index, extent of blood loss and soft pancreatic parenchyma as risk factors related to POPF. Multivariate analysis identified extent of blood loss and soft pancreatic parenchyma as significant risk factors. Placement of a long-internal stent during PJ did not reduce POPF after PD in patients with a main pancreatic duct of small diameter. Copyright © 2017 IJS Publishing Group Ltd.

Perceptions of government knowledge and control over contributions of aid organizations and INGOs to health in Nepal: a qualitative study

PubMed Central

2013-01-01

Background Almost 50% of the Nepali health budget is made up of international aid. International Non-Governmental Organizations working in the field of health are able to channel their funds directly to grass root level. During a 2010 conference, the Secretary of Population stated that the government has full knowledge and control over all funds and projects coming to Nepal. However, there are no documents to support this. The study aims to assess government and partner perceptions on whether Government of Nepal currently has full knowledge of contributions of international aid organizations and International Non-Governmental Organizations to health in Nepal and to assess if the government is able to control all foreign contributions to fit the objectives of Second Long Term Health Plan (1997–2017). Methods A qualitative study was performed along with available literature review. Judgmental and snowball sampling led to 26 in depth interviews with key informants from the government, External Development Partners and International Non-Governmental Organizations. Results were triangulated based on source of data. Representatives of the Department of Health Services declined to be interviewed. Data collection was done until researchers felt data saturation had been reached with each group of key informants. Results While Ministry of Health and Population leads the sector wide approach that aims to integrate all donor and International Non-Governmental Organization contributions to health and direct them to the government’s priority areas, questions were raised around its capacity to do so. Similarly, informants questioned the extent to which Social Welfare Council was able to control all International Non-Governmental Organizations contributions. Political tumult, corruption in the government, lack of human resources in the government, lack of coordination between government bodies, convoluted bureaucracy, and unreliability of donor and International Non-Governmental Organization contributions were identified as the main reasons for difficulties in aid integration. Conclusions Despite its commitment to coordinate and control development assistance to the health sector, and its leadership position of the Sector Wide Approach, complete knowledge and effective coordination of all international contributions remains a challenge and is hampered by issues within the government as well as among External Development Partners and International Non-Governmental Organizations.

An adaptive nonlinear internal-model control for the speed control of homopolar salient-pole BLDC motor

NASA Astrophysics Data System (ADS)

CheshmehBeigi, Hassan Moradi

2018-05-01

In this paper, a novel speed control method for Homopolar Brushless DC (HBLDC) motor based on the adaptive nonlinear internal-model control (ANIMC) is presented. Rotor position information is obtained online by the Hall-Effect sensors placed on the motor's shaft, and is used to calculate the accurate model and accurate inverse model of the HBLDC motor. The online inverse model of the motor is used in the controller structure. To suppress the reference ? error, the negative feedback of difference between the motor speed and its model output ? is applied in the proposed controller. An appropriate signal is the output of the controller, which drives the power switches to converge the motor speed to the constant desired speed. Simulations and experiments are carried out on a ? three-phase HBLDC motor. The proposed drive system operates well in the speed response and has good robustness with respect to the disturbances. To validate the theoretical analysis, several experimental results are discussed in this paper.

Self-Tuning Fully-Connected PID Neural Network System for Distributed Temperature Sensing and Control of Instrument with Multi-Modules.

2016-10-14

High integration of multi-functional instruments raises a critical issue in temperature control that is challenging due to its spatial-temporal complexity. This paper presents a multi-input multi-output (MIMO) self-tuning temperature sensing and control system for efficiently modulating the temperature environment within a multi-module instrument. The smart system ensures that the internal temperature of the instrument converges to a target without the need of a system model, thus making the control robust. The system consists of a fully-connected proportional-integral-derivative (PID) neural network (FCPIDNN) and an on-line self-tuning module. The experimental results show that the presented system can effectively control the internal temperature under various mission scenarios, in particular, it is able to self-reconfigure upon actuator failure. The system provides a new scheme for a complex and time-variant MIMO control system which can be widely applied for the distributed measurement and control of the environment in instruments, integration electronics, and house constructions.

Internal versus external motivation in referral of primary care patients with depression to an internet support group: randomized controlled trial.

Depressive disorders and symptoms affect more than one-third of primary care patients, many of whom do not receive or do not complete treatment. Internet-based social support from peers could sustain depression treatment engagement and adherence. We do not know whether primary care patients will accept referral to such websites nor do we know which methods of referral would be most effective. We conducted a randomized clinical trial to determine whether (1) a simple generic referral card (control), (2) a patient-oriented brochure that provided examples of online postings and experience (internal motivation), or (3) a physician letter of recommendation (external motivation) would generate the greatest participation in a primary care Internet depression treatment support portal focused around an Internet support group (ISG). We used 3 offline methods to identify potential participants who had not used an ISG in the past 6 months. Eligibility was determined in part by a brief structured psychiatric interview based on the Patient Health Questionnaire-9 (PHQ-9). After consent and enrollment, participants were randomly assigned to 1 of 3 groups (control, internal motivation, or external motivation). We constructed a portal to connect primary care patients to both fact-based information and an established ISG (Psycho-Babble). The ISG allowed participants to view messages and then decide if they actually wished to register there. Participation in the portal and the ISG was assessed via automated activity tracking. Fifty participants were assigned to the 3 groups: a motivation-neutral control group (n=18), an internal motivation group (n=19), and an external motivation group (n=13). Of these participants, 31 (62%) visited the portal; 27 (54%) visited the ISG itself. The internal motivation group showed significantly greater participation than the control group on several measures. The external motivation group spent significantly less time logged onto the portal than the control group. The internal motivation group showed significantly greater participation than the external motivation group on several measures. Referral of primary care patients with depressive disorders and symptoms to an ISG is feasible even if they have never previously used one. This may best be accomplished by enhancing their internal motivation.

Co-rumination, defined as repetitive, problem-focused talk explains higher levels of friendship quality in youth (Rose, 2002) and increased levels of anxiety/depression in females. Middle adolescents (N = 146) participated in a study of co-rumination, individual coping, externalizing/internalizing problems, and peer functioning. Consistent with past research, girls reported higher levels of co-rumination and internalizing symptoms. Co-rumination was also positively correlated with self-reports, but not teacher reports, of anxiety/depression and aggressive behavior. Both self-reported number of friends and teacher-rated social acceptance were negatively associated with co-rumination. Co-rumination partially accounted for the significant indirect effect of gender on internalizing symptoms. Additionally, co-rumination was associated with internalizing and externalizing symptoms but not individual coping efforts. Finally, co-rumination accounted for a unique amount of variance in internalizing symptoms, controlling for externalizing problems and secondary control coping. Theoretical implications and the importance of including broad domains of adjustment and peer functioning in future investigations of co-rumination are discussed.

Abstract Background Health-related control and self-efficacy beliefs can be assessed in the general population using Multidimensional Health Locus of Control-A subscales (MHLC-A) and the General Self-Efficacy Scale (GSES), respectively. Objective To test construct validity, internal consistency, reliability (test-retest) and ceiling and floor effects of Portuguese-Brazil versions of MHLC-A and GSES. Method Civil servants (N=2901) enrolled in a large Brazilian cohort were included. A new version of the GSES was produced (GSES-Brazil). Procedures for cross-cultural adaptation and testing of psychometric properties followed well-accepted international guidelines. Results Confirmatory factor analyses yielded the following indices: MHLC-A (tridimensional model): χ2[df]=223.45[132], p-value <0.01; CFI=0.87; TLI=0.85; RMSEA=0.07 (0.07-0.08); WRMR=3.00. GSES-Brazil (unidimensional model): χ2[df]=788.60[35], p-value <0.01; CFI=0.95; TLI=0.94; RMSEA=0.09 (0.08-0.09); WRMR=2.50. Cronbach’s alpha coefficients and Intraclass Correlation Coefficients (ICC2,1) ranged from 0.57 (0.54-0.59) and 0.57 (0.47-0.65) for MHLC-A internality to 0.80 (0.79-0.81) and 0.71 (0.66-0.77) for GSES-Brazil, respectively. There was no evidence of ceiling and floor effects. Convergent validity analyses provided further support for construct validity of both scales. Conclusion These findings support the use of the newly developed version of GSES-Brazil for the assessment of general self-efficacy of adult Brazilians. Internal consistency was lower than ideal for MHLC-A, indicating these subscales may need further refinements to provide a more psychometrically sound measure of control beliefs. PMID:27878226

Selection of an Alternate Biocide for the ISS Internal Thermal Control System Coolant, Phase 2

Wilson, Mark E.; Cole, Harold; Weir, Natalee; Oehler, Bill; Steele, John; Varsik, Jerry; Lukens, Clark

2004-01-01

The ISS (International Space Station) ITCS (Internal Thermal Control System) includes two internal coolant loops that utilize an aqueous based coolant for heat transfer. A silver salt biocide had previously been utilized as an additive in the coolant formulation to control the growth and proliferation of microorganisms within the coolant loops. Ground-based and in-flight testing demonstrated that the silver salt was rapidly depleted, and did not act as an effective long-term biocide. Efforts to select an optimal alternate biocide for the ITCS coolant application have been underway and are now in the final stages. An extensive evaluation of biocides was conducted to down-select to several candidates for test trials and was reported on previously. Criteria for that down-select included: the need for safe, non-intrusive implementation and operation in a functioning system; the ability to control existing planktonic and biofilm residing microorganisms; a negligible impact on system-wetted materials of construction; and a negligible reactivity with existing coolant additives. Candidate testing to provide data for the selection of an optimal alternate biocide is now in the final stages. That testing has included rapid biocide effectiveness screening using Biolog MT2 plates to determine minimum inhibitory concentration (amount that will inhibit visible growth of microorganisms), time kill studies to determine the exposure time required to completely eliminate organism growth, materials compatibility exposure evaluations, coolant compatibility studies, and bench-top simulated coolant testing. This paper reports the current status of the effort to select an alternate biocide for the ISS ITCS coolant. The results of various test results to select the optimal candidate are presented.

Development of pseudoviral competitive internal controls for RT-PCR laboratory detection of dengue virus. The internal controls target gene were obtained by insertion of a 180 bp non-related DNA fragment into RT-PCR detection target of dengue virus between the forward and reverse PCR primer binding regions. A yellow florescence protein reporter gene was induced at downstream of internal controls target gene via internal ribosome entry site gene. HEK 293T cells were transfected with plasmid containing this whole cassette and lentiviral packaging support plasmid. Pseudoviral particle was recovered from the supernatant and analyzed quantitatively and qualitatively in simulated samples at the same tube under different experimental conditions. The established pseudoviral competitive internal controls can be used in the RT-PCR detection of different serotype dengue virus and the whole detection process can be monitored. The obtained fragment is easy to be differentiated in agarose electrophoresis. The pseudoviral competitive internal controls could be used for the quality control of the laboratory diagnosis process, simple to prepare, stable for storage, easy to be transformed into internal controls for other RNA virus.

Test the hypothesis that reductions in thin-ideal internalization and body dissatisfaction mediate the effects of a dissonance-based eating disorder prevention program on reductions in eating disorder symptoms over 1-year follow-up. Data were drawn from a randomized effectiveness trial in which 306 female high school students (mean age = 15.7 years, SD = 1.1) with body image concerns were randomized to the 4-session dissonance-based prevention program or an educational brochure control condition, wherein school counselors and nurses were responsible for participant recruitment and intervention delivery. Dissonance-intervention participants showed greater reductions in thin-ideal internalization, body dissatisfaction, and eating disorder symptoms; change in thin-ideal internalization predicted change in body dissatisfaction and symptoms; change in body dissatisfaction predicted change in symptoms; and all indirect effects were significant. Change in thin-ideal internalization fully mediated the effects of intervention condition on change in body dissatisfaction and partially mediated the effects on symptoms; change in body dissatisfaction partially mediated the effect of intervention condition on change in symptoms. Findings provided support for the intervention theory of this eating disorder prevention program over longer term follow-up, extending the evidence base for this effective intervention.

A primary goal for ITER and prospective fusion power reactors is to achieve controlled long-pulse/steady-state burning plasmas. For elongated divertor plasmas, both the vertical position and current profile have to be precisely controlled to optimize performance and prevent disruptions. An eleven-channel laser-based POlarimeter-INTerferometer (POINT) system has been developed for measuring the internal magnetic field in the EAST tokamak and can be used to obtain the plasma current profile and vertical position. Current profiles are determined from equilibrium reconstruction including internal magnetic field measurements as internal constraints. Horizontally-viewing chords at/near the mid-plane allow us to determine plasma vertical position non-inductively with subcentimeter spatial resolution and time response up to 1 s. The polarimeter-based position measurement, which does not require equilibrium reconstruction, is benchmarked against conventional flux loop measurements and can be exploited for feedback control.

Ecotechnology: basis of a new immission concept in water pollution control.

PubMed

Benndorf, J

2005-01-01

Beyond the traditional load reduction also an ecosystem-internal mechanism can be used to minimise the effects of water pollution. The control of the internal mechanisms is achieved through the optimisation of the ecosystem structure. This ecotechnology principle is based on the idea to reduce as much as possible the gap between the current (suboptimal) structural status and the optimum structure by intentional manipulations. The spectrum of such manipulations is very broad. A few examples are demonstrated. They comprise physical (e.g. stream morphology), chemical (e.g. enhancing the redox potential at the sediment-water interface) and biological (e.g. enhancing stocks of predatory fishes) control measures. It can be supposed that a new immission concept including the ecotechnology principle could be much more adequate to the demand of modern water pollution control than the traditional emission and imission concepts.

The inhalation of radioactive particles is the largest cause of an internal radiation dose. Airborne radioactivity measurements are necessary to ensure that the control measures are and continue to be effective. Regulations govern the allowable effective dose equivalent to an individual. The effective dose equivalent is determined by combining the external and internal dose equivalent values. Typically, airborne radioactivity levels are maintained well below allowable levels to keep the total effective dose equivalent small.

Ireland, Michael J; Clough, Bonnie; Gill, Kim; Langan, Fleur; O'Connor, Angela; Spencer, Lyndall

2017-04-01

Stress and burnout are highly prevalent among medical doctors, and are associated with negative consequences for doctors, patients, and organizations. The purpose of the current study was to examine the effectiveness of a mindfulness training intervention in reducing stress and burnout among medical practitioners, by means of a Randomised Controlled Trial design. Participants were 44 intern doctors completing an emergency department rotation in a major Australian hospital. Participants were randomly assigned to either an active control (one hour extra break per week) or the 10-week mindfulness training intervention. Measures of stress and burnout were taken pre-, mid- and post intervention. Participants undergoing the 10-week mindfulness training program reported greater improvements in stress and burnout relative to participants in the control condition. Significant reduction in stress and burnout was observed for participants in the mindfulness condition. No such reductions were observed for participants in the control condition. Mindfulness interventions may provide medical practitioners with skills to effectively manage stress and burnout, thereby reducing their experience of these symptoms. It is likely that doctors would benefit from the inclusion of such a training program as a part of their general medical education.

Background. About 65% of cancer deaths globally occur in low to middle income countries (LMICs) where prioritization and allocation of resources to cancer care are often quite poor. In the absence of governmental focus on this problem, public-private partnerships may be an avenue to provide effective cancer control. Methods. This manuscript highlights the establishment of a nongovernmental organization (NGO) to stimulate the development of partnerships between oncology professionals, private enterprise, and academic institutions, both locally and internationally. Examples of capacity building, grant support, establishment of collaborative networks, and the development of a facility to provide clinical care are highlighted. Results. Collaborations were established between oncology professionals at academic institutions in the US and Nigeria. Cancer control workshops were conducted in Nigeria with grant support from the Union for International Cancer Control (UICC). A monthly tumor board conference was established at LASUTH in Lagos, and further capacity building is underway with grant support from the United States NCI. An outpatient, privately funded oncology clinic in Lagos has been launched. Conclusion. In LMICs, effective partnership between public and private institutions can lead to tangible strides in cancer control. The use of creative healthcare financing models can also support positive change. PMID:28070189

Hinge Moments of Sealed-Internal-Balance Arrangements for Control Surfaces I : Theoretical Investigation

NASA Technical Reports Server (NTRS)

Murray, Harry E.; Erwin, Mary A.

1945-01-01

The results of a theoretical analysis of the hinge-moment characteristics of various sealed-internal-balance arrangements for control surfaces are presented. The analysis considered overhands sealed to various types of wing structure by flexible seals spanning gaps of various widths or sealed to the wing structure by a flexible system of linked plates. Leakage was not considered; the seal was assumed to extend the full spanwise length of the control surface. The effect of the developed width of the flexible seal and of the geometry of the structure to which the seal was anchored was investigated, as well as the effect of the gap width that is sealed. The results of the investigation indicated that the most nearly linear control-surface hinge-moment characteristics can probably be obtained from a flexible seal over a narrow gap (about 0.1 of the overhang chord), which is so installed that the motion of the seal is restricted to a region behind the point of attachment of the seal to the wing structure. Control-surface hinge moments that tend to be high at large deflections and low or overbalanced at small deflections will result if a very narrow seal is used.

It is hard for metal nanoparticle catalysts to control the selectivity of a catalytic reaction in a simple process. In this work, we obtain active Au nanoparticle catalysts with high selectivity for the hydrogenation reaction of aromatic nitro compounds, by simply employing spine-like Au nanoparticles. The density functional theory (DFT) calculations further elucidate that the morphological effect on thermal selectivity control is an internal key parameter to modulate the nitro hydrogenation process on the surface of Au spines. These results show that controlled morphological effects may play an important role in catalysis reactions of noble metal NPs with high selectivity.

The authors describe the aims and principles of trypanosomiasis control and discuss the individual techniques of control and the ways in which these can be channelled through a general rural health service. They argue that, given the circumstances at present prevailing in rural Africa, a broad-based general public health service should be established before specific campaigns for control or eradication of sleeping-sickness, or indeed any other specific diseases, are instituted. They emphasize the necessity of international co-operation for effective trypanomiasis control.

This research aimed to examine how affective commitment to the supervisor related to nurses' well- and ill-being, and to explore the moderating function of internal locus of control in these relationships. Little is known about the effects of affective commitment to the supervisor on well- and ill-being, even less so in the nursing profession. Moreover, previous studies suggested that nurses' psychological reactions to their work environment might vary as a function of their individual characteristics. This cross-sectional research used a questionnaire survey to explore the hypothesised relationships in a sample of 100 female certified nursing assistants. The results revealed that affective commitment to the supervisor was most strongly related to job satisfaction and well-being, and associated with lower levels of emotional exhaustion, when the internal locus of control was high. The present study emphasises the importance of a high quality relationship between nurses and their supervisors in order to promote their psychological health, and underscores the importance of individual characteristics. This research indicates how nurses' psychological health could be promoted by fostering their affective commitment to the supervisor. It also emphasises that managers' relationships with their subordinates should be adjusted as a function of nurses' individual characteristics. © 2017 John Wiley & Sons Ltd.

Effects of knowledge and internal locus of control in groups of health care workers judging likelihood of pathogen transfer.

A study was conducted to measure the effects of attitudes and beliefs on the risk judgments of health care workers. Lack of hand hygiene compliance is a worldwide issue in health care, contributing to infections, fatalities, and increased health care costs. Human factors methods are a promising solution to the problem of compliance, although thus far, the concentration has been on process and engineering methods, such as the design of no-touch sinks. Factors internal to the health care worker, such as their attitudes and beliefs about hand hygiene, have received less attention. For this study, three groups of health care workers completed measures of attitudes, control beliefs, and hand hygiene knowledge. They then provided risk judgments of touching various surfaces via a factorial survey. Attitudes, knowledge, control beliefs, and surface type all predicted the risk judgments of the sample of health care workers, with differences between professional groups. Health care workers perceive less risk when touching surfaces,which may explain historically low rates of hand hygiene compliance after surface contact. Although more research is needed to directly connect risk judgments to failures of hand hygiene, the current results can inform interventions targeting the internal attitudes and beliefs of health care workers.

How to effectively design public health interventions: Implications from the interaction effects between socioeconomic status and health locus of control beliefs on healthy dietary behaviours among US adults.

PubMed

Jang, Kyungeun; Baek, Young Min

2018-04-16

This study investigated whether individuals with different socioeconomic status (SES) should be provided differently tailored health messages to promote healthy dietary behaviour (HDB). Prior research has suggested that people with different SESs tend to exhibit different types of beliefs about health, but it remains unclear how SES interacts with these beliefs to influence health outcomes. To better understand the differences in HDB between high- and low-SES populations and propose effective intervention strategies, we examined (i) how SES is associated with HDB, (ii) how internal health locus of control (HLC) and powerful others HLC are associated with HDB, and (iii) how SES interacts with internal and powerful others HLC to influence HDB. Using data from the Annenberg National Health Communication Survey, collected from 2005 to 2012 (N = 6,262) in the United States, hierarchical multiple regression analyses were conducted. Education level was found to be positively associated with HDB, while income level was not. Both internal and powerful others HLC beliefs were positively associated with HDB. The positive relationship between internal HLC and HDB strengthened as the level of education and income increased, whereas the positive relationship between powerful others HLC and HDB weakened as respondents' education level increased. These results suggest that the design and delivery of communication messages should be tailored to populations' specific SES and HLC beliefs for effective public health interventions. For example, messages enhancing internal HLC (e.g. providing specific skills and knowledge about health behaviours) might be more helpful for the richer and more-educated, while messages appealing to one's powerful others HLC beliefs (e.g. advice on health lifestyles given by well-known health professionals) might be more effective for less-educated people. © 2018 John Wiley & Sons Ltd.

Comprehensive interventions including components of stigma and discrimination reduction in schizophrenia in low- and middle-income countries (LMICs) are lacking. We developed a community-based comprehensive intervention to evaluate its effects on clinical symptoms, social functioning, internalized stigma and discrimination among patients with schizophrenia. A randomized controlled trial including an intervention group (n = 169) and a control group (n = 158) was performed. The intervention group received comprehensive intervention (strategies against stigma and discrimination, psycho-education, social skills training and cognitive behavioral therapy) and the control group received face to face interview. Both lasted for nine months. Participants were measured at baseline, 6 months and 9 months using the Internalized Stigma of Mental Illness scale (ISMI), Discrimination and Stigma Scale (DISC-12), Global Assessment of Functioning (GAF), Schizophrenia Quality of Life Scale (SQLS), Self-Esteem Scale (SES), Brief Psychiatric Rating Scale (BPRS) and PANSS negative scale (PANSS-N). Insight and medication compliance were evaluated by senior psychiatrists. Data were analyzed by descriptive statistics, t-test, chi-square test or Fisher's exact test. Linear Mixed Models were used to show intervention effectiveness on scales. General Linear Mixed Models with multinomial logistic link function were used to assess the effectiveness on medication compliance and insight. We found a significant reduction on anticipated discrimination, BPRS and PANSS-N total scores, and an elevation on overcoming stigma and GAF in the intervention group after 9 months. These suggested the intervention may be effective in reducing anticipated discrimination, increasing skills overcoming stigma as well as improving clinical symptoms and social functioning in Chinese patients with schizophrenia.

Online Evaluative Conditioning Did Not Alter Internalized Homonegativity or Self-Esteem in Gay Men.

PubMed

Fleming, John B; Burns, Michelle Nicole

2017-09-01

Internalized homonegativity is linked to psychological distress in sexual minorities and is thus a potential treatment target in this population. Previous studies have shown that evaluative conditioning (EC) can modify self-esteem, another self-directed attitude. The present study aimed to determine if EC deployed over the Internet could modify self-esteem and internalized homonegativity. Gay men recruited online (N = 184) were randomly assigned to a control group or an experimental condition. Participants completed self-reports and measures of implicit attitudes before and after being exposed to control or experimental tasks. The study was administered online. There were no significant between-group differences on implicit or explicit self-esteem (ps > .49) or internalized homonegativity (ps > .28). Despite past laboratory success, Internet-based EC did not produce significant effects in implicit or explicit self-directed attitudes. Post hoc analyses did not support any of several potential explanations for these results. Alternative explanations are discussed. © 2016 Wiley Periodicals, Inc.

Neighborhood disadvantage as a moderator of the association between harsh parenting and toddler-aged children’s internalizing and externalizing problems

Neighborhood dangerousness and belongingness were expected to moderate associations between harsh parenting and toddler-aged children’s problem behaviors. Fifty-five predominantly African American mothers participated with their 2-year old children. Neighborhood danger, neighborhood belongingness, and children’s problem behaviors were measured with mothers’ reports. Harsh parenting was measured with observer ratings. Analyses considered variance common to externalizing and internalizing problems, using a total problems score, and unique variance, by controlling for internalizing behavior when predicting externalizing behavior, and vice-versa. Regarding the common variance, only the main effects of neighborhood danger and harsh parenting were significantly associated with total problem behavior. In contrast, after controlling for externalizing problems, the positive association between harsh parenting and unique variance in internalizing problems became stronger as neighborhood danger increased. No statistically significant associations emerged for the models predicting the unique variance in externalizing problems or models considering neighborhood belongingness. PMID:21355648

This study utilized structural equation modeling to examine the associations among parental guilt induction (a form of psychological control), youth cognitive style, and youth internalizing symptoms, with parents and youth participating in a randomized controlled trial of a family-based group cognitive–behavioral preventive intervention targeting families with a history of caregiver depression. The authors present separate models utilizing parent report and youth report of internalizing symptoms. Findings suggest that families in the active condition (family-based group cognitive–behavioral group) relative to the comparison condition showed a significant decline in parent use of guilt induction at the conclusion of the intervention (6 months postbaseline). Furthermore, reductions in parental guilt induction at 6 months were associated with significantly lower levels of youth negative cognitive style at 12 months. Finally, reductions in parental use of guilt induction were associated with lower youth internalizing symptoms 1 year following the conclusion of the intervention (18 months postbaseline).

Double closed-loop cascade control for lower limb exoskeleton with elastic actuation.

PubMed

2015-01-01

Unlike traditional rigid actuators, the significant features of Series Elastic Actuator (SEA) are stable torque control, lower output impedance, impact resistance and energy storage. Recently, SEA has been applied in many exoskeletons. In such applications, a key issue is how to realize the human-exoskeleton movement coordination. In this paper, double closed-loop cascade control for lower limb exoskeleton with SEA is proposed. This control method consists of inner SEA torque loop and outer contact force loop. Utilizing the SEA torque control with a motor velocity loop, actuation performances of SEA are analyzed. An integrated exoskeleton control system is designed, in which joint angles are calculated by internal encoders and resolvers and contact forces are gathered by external pressure sensors. The double closed-loop cascade control model is established based on the feedback signals of internal and external sensor. Movement experiments are accomplished in our prototype of lower limb exoskeleton. Preliminary results indicate the exoskeleton movements with pilot can be realized stably by utilizing this double closed-loop cascade control method. Feasibility of the SEA in our exoskeleton robot and effectiveness of the control method are verified.

Cancer has become one of the leading causes of morbidity and mortality in low- and middle-income countries (LMICs), where 60% of the world's total new cases are diagnosed. The challenge for effective control of cancer is multifaceted. It mandates integration of effective cancer prevention, encouraging early detection, and utilization of resource-adapted therapeutic and supportive interventions. In the resource-constrained setting, it becomes challenging to deliver each service optimally, and efficient allocation of resources is the best way to improve the outcome. This concept was translated into action through development of resource-stratified guidelines, pioneered by the Breast Health Global Initiative (BHGI), and later adopted by most oncology societies in an attempt to help physicians deliver the best possible care in a limited-resource setting. Improving outcome entails collaboration between key stakeholders, including the pharmaceutical industry, local and national health authorities, the World Health Organization (WHO), and other nonprofit, patient-oriented organizations. Therefore, we started to observe global health initiatives-led by ASCO, the Union for International Cancer Control (UICC), and the WHO-to address these challenges at the international level. This article discusses some of these initiatives.

Optimizing chaos time-delay signature in two mutually-coupled semiconductor lasers through controlling internal parameters

NASA Astrophysics Data System (ADS)

Mu, Penghua; Pan, Wei; Yan, Lianshan; Luo, Bin; Zou, Xihua

2017-04-01

In this contribution, the effects of two key internal parameters, i.e. the linewidth-enhancement factor (α) and gain nonlinearity (𝜀), on time-delay signatures (TDS) concealment of two mutually-coupled semiconductor lasers (MCSLs) are numerically investigated. In particular, the influences of α and 𝜀 on the TDS concealment are compared and discussed systematically by setting different values of frequency detuning (Δf) and injection strength (η). The results show that the TDS can be better suppressed with high α or lower 𝜀 in the MCSLs. Two sets of desired optical chaos with TDS being strongly suppressed can be generated simultaneously in a wide injection parameter plane provided that α and 𝜀 are properly chosen, indicating that optimizing TDS suppression through controlling internal parameters can be generalized to any delayed-coupled laser systems.

β-arrestins negatively control human adrenomedullin type 1-receptor internalization.

Adrenomedullin (AM) is a potent hypotensive peptide that exerts a powerful variety of protective effects against multiorgan damage through the AM type 1 receptor (AM 1 receptor), which consists of the calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein 2 (RAMP2). Two β-arrestin (β-arr) isoforms, β-arr-1 and β-arr-2, play a central role in the agonist-induced internalization of many receptors for receptor resensitization. Notably, β-arr-biased agonists are now being tested in phase II clinical trials, targeting acute pain and acute heart failure. Here, we examined the effects of β-arr-1 and β-arr-2 on human AM 1 receptor internalization. We constructed a V5-tagged chimera in which the cytoplasmic C-terminal tail (C-tail) of CLR was replaced with that of the β 2 -adrenergic receptor (β 2 -AR), and it was transiently transfected into HEK-293 cells that stably expressed RAMP2. The cell-surface expression and internalization of the wild-type or chimeric receptor were quantified by flow cytometric analysis. The [ 125 I]AM binding and the AM-induced cAMP production of these receptors were also determined. Surprisingly, the coexpression of β-arr-1 or -2 resulted in significant decreases in AM 1 receptor internalization without affecting AM binding and signaling prior to receptor internalization. Dominant-negative (DN) β-arr-1 or -2 also significantly decreased AM-induced AM 1 receptor internalization. In contrast, the AM-induced internalization of the chimeric AM 1 receptor was markedly augmented by the cotransfection of β-arr-1 or -2 and significantly reduced by the coexpression of DN-β-arr-1 or -2. These results were consistent with those seen for β 2 -AR. Thus, both β-arrs negatively control AM 1 receptor internalization, which depends on the C-tail of CLR. Copyright © 2017 Elsevier Inc.

2013-01-01

To examine the effects of reading exercise-related magazine articles (health, appearance, or control) and the moderating effects of exercise self-identity on reasons for exercise and perceptions of attractiveness, among women in first year university. An additional purpose was to use a thought listing technique, the results of which were examined for evidence of internalization of the exercise-related messages. Female students in their first year of studies between September 2010 and April 2011 (N = 173; mean age = 19.31 years, mean body mass index = 22.01). Participants read a health, appearance, or control article, listed thoughts, and completed questionnaires measuring reasons for exercising, physical self-perception, and exercise self-identity. Participants in the health condition rated exercise for health significantly higher than control condition participants. Participants with high exercise self-identity rated attractiveness as a reason for exercising significantly higher than low exercise self-identity participants in both the health and appearance conditions. Participants with higher internalization scores (i.e., accepted societal norms of appearance) reported exercising for attractiveness reasons more so than participants with lower internalization scores. The good news is that health messages may be influential and result in wanting to exercise for health purposes. However, exercising for attractiveness was rated highly by participants with high exercise identity who read either the health or appearance articles. Health and appearance are not necessarily distinct concepts for female undergraduate students and the media may influence cited reasons for exercise.

Clinical comparative analysis on unstable pelvic fractures in the treatment with percutaneous sacroiliac screws and sacroiliac joint anterior plate fixation.

To investigate clinical efficacy of unstable pelvic fractures in the treatment with percutaneous sacroiliac screws and sacroiliac joint anterior plate fixation. 64 patients with unstable pelvic fractures were selected in the hospital from January 2008 to June 2011, and were randomly divided into two groups.(32 patients with sacroiliac anterior plate fixation as the control group, and another 32 patients with percutaneous sacroiliac screw internal fixation as the observation group). The perioperative period clinical indicators, postoperative Matta score, postoperative Majeed function score of all patients were compared and analyzed. The operation time, intraoperative blood loss, wound total length, postoperative fever time, duration of hospitalization in the observation group were significantly less than those in the control group. The complication rate (3.1%) in the observation group was lower than that in the control group (21.9%). The rate of Matta score excellent (96.9%) in the observation group was higher than that in the control group (81.2%) after the treatment. The rate of Majeed function score excellent (93.8%) in the observation group was significantly higher than that in the control group (75%) after the treatment. Percutaneous sacroiliac screw internal fixation in the treatment of unstable pelvic fractures has less injury, less bleeding, less pain and rapid recovery which is a safe and effective minimally invasive operation method. The clinical curative effect of percutaneous sacroiliac screw internal fixation is better than anterior plate fixation for the treatment of sacroiliac joint. The full preparation before the surgery and patients with positive can substantially reduce the occurrence of complications rate.

Peer sexual harassment: finding voice, changing culture--an intervention strategy for adolescent females.

Martin, Jennifer L

2008-01-01

This exploratory intervention study examines the effectiveness of a single-sex women's studies course in reducing sexual harassment in an at-risk high school. It was hypothesized that the young women's loci of control would become more internal as a result of the course and participants would feel they had more control over their lives. Findings indicate that participants' knowledge of sexual harassment gained from the intervention had been retained and reports of sexual harassment increased. Administrative referrals for sexual harassment within the school were reduced by one third during the semester following the intervention. Participants' perceptions of their levels of internality increased over time.

Control of rotordynamic instability in a typical gas turbine's power system

Veikos, N. M.; Page, R. H.; Tornillo, E. J.

1984-01-01

The effect of rotor internal friction on the system's stability was studied when operated above the first critical speed. This internal friction is commonly caused by sliding press fits or sliding splines. Under conditions of high speed and low bearing damping, these systems will occassionally whirl at a frequency less than the shaft's rotational speed. This subsynchronous precession is a self excited phenomenon and stress reversals are created. This phenomenon was observed during engine testing. The reduction of spline friction and/or the inclusion of squeeze film damping have controlled the instability. Case history and the detail design of the squeeze film dampers is discussed.

Background Simulation training may improve proficiency at and reduces complications from central venous catheter (CVC) placement, but the scope of simulation’s effect remains unclear. This randomized controlled trial evaluated the effects of a pragmatic CVC simulation program on procedural protocol adherence, technical skill, and patient outcomes. Methods Internal medicine interns were randomized to standard training for CVC insertion or standard training plus simulation-based mastery training. Standard training involved a lecture, a video-based online module, and instruction by the supervising physician during actual CVC insertions. Intervention-group subjects additionally underwent supervised training on a venous access simulator until they demonstrated procedural competence. Raters evaluated interns’ performance during internal jugular CVC placement on actual patients in the medical intensive care unit. Generalized estimating equations were used to account for outcome clustering within trainees. Results We observed 52 interns place 87 CVCs. Simulation-trained interns exhibited better adherence to prescribed procedural technique than interns who received only standard training (p=0.024). There were no significant differences detected in first-attempt or overall cannulation success rates, mean needle passes, global assessment scores or complication rates. Conclusions Simulation training added to standard training improved protocol adherence during CVC insertion by novice practitioners. This study may have been too small to detect meaningful differences in venous cannulation proficiency and other clinical outcomes, highlighting the difficulty of patient-centered simulation research in settings where poor outcomes are rare. For high-performing systems, where protocol deviations may provide an important proxy for rare procedural complications, simulation may improve CVC insertion quality and safety. PMID:26154250

With regards to the importance of women's beliefs in improving pregnancy outcomes, this study was performed to determine the perceived internal control on future pregnancy outcomes and its related factors in women who participated in pre-marital counseling. In a cross-sectional study, women's perceived internal control was investigated. The study population comprised the women in reproductive age of whom 400 were selected by random sampling. Data collection instrument was a questionnaire consisting of demographic, pre-conceptional care, and internal control questions. Two categories of favorite and not favorite levels of internal control were defined based on the total score. The validity of the questionnaire was determined via content validity method by use of experts' opinion and its reliability was evaluated through the calculation of Cronbach's alpha coefficient which was 0.76. Data were analyzed through frequency tables, correlation coefficient, and Chi-square test at the confidence level of 0.95. Two hundred sixty-five (65%) women had a good perceived internal control and it was significantly associated with the age, educational level, and hearing about pre-conceptional care. The internal control score also showed a positive and significant correlation with both age and the subject knowledge about folic acid (r = 0.19 and r = 0.15, respectively). The majority of women had a favorite perceived internal control. Since age and educational level were the affecting factors on the perceived internal control of women, promoting the level of internal control in young women and those with low education in pre-marital counseling classes seems necessary.

Infection control activities in the international research setting include the development of meaningful and effective policies on specific topics such as hand and respiratory hygiene. Prevention of infection in health care workers and management of occupational exposure to transmissible agents are important aspects of the role of an infection control practitioner. Hand hygiene reduces health care associated infections and practices may be implemented in the research setting.

Continuous Cognitive Task Promotes Greater Postural Stability than an Internal or External Focus of Attention in Older Adults.

Richer, Natalie; Polskaia, Nadia; Lajoie, Yves

2017-01-01

Background/Study Context: Recent evidence suggests that removing attention from postural control using either an external focus or a cognitive task will improve stability in healthy young adults. Due to increases in attentional requirements of upright stance in older adults, it is unclear if similar benefits would be observed in this population. The aim of the present study was to examine the effect of attentional focus and of a continuous cognitive task on postural control in older adults. Sixteen healthy older adults (71.9 ± 4.32 years) were asked to stand quietly on a force platform with feet together in three different conditions: internal focus (minimizing movement of the hips), external focus (minimizing movement of markers placed on the hips), and cognitive task (silently counting the occurrence of a single digit in a 3-digit number sequence). A one-way analysis of variance with repeated measures on condition was performed for each postural control measure. Hypotheses were partially supported because the cognitive task led to greater stability than both focus conditions, as evidenced by a smaller sway area (p < .01, η p 2 = .41), reduced sway variability (anterior-posterior: p = .001, η p 2 = .37; medial-lateral: p < .0001, η p 2 = .49), and higher mean power frequency in the anterior-posterior direction (p = .01, η p 2 = .78). However, no difference was observed between internal and external focus conditions. A continuous, attention-demanding cognitive task significantly improved stability in older adults compared with an internal or external focus of attention. This suggests that older adults were able to effectively allocate their attention away from postural control, allowing a more automatic type of control to operate. Future studies should investigate a variety of cognitive tasks to determine the degree of postural improvement that can be observed in older adults.

Droplet digital PCR (ddPCR) allows absolute quantification of nucleic acids and has potential for improved non-invasive detection of DNA methylation. For increased precision of the methylation analysis, we aimed to develop a robust internal control for use in methylation-specific ddPCR. Two control design approaches were tested: (a) targeting a genomic region shared across members of a gene family and (b) combining multiple assays targeting different pericentromeric loci on different chromosomes. Through analyses of 34 colorectal cancer cell lines, the performance of the control assay candidates was optimized and evaluated, both individually and in various combinations, using the QX200™ droplet digital PCR platform (Bio-Rad). The best-performing control was tested in combination with assays targeting methylated CDO1 , SEPT9 , and VIM . A 4Plex panel consisting of EPHA3 , KBTBD4 , PLEKHF1 , and SYT10 was identified as the best-performing control. The use of the 4Plex for normalization reduced the variability in methylation values, corrected for differences in template amount, and diminished the effect of chromosomal aberrations. Positive Droplet Calling (PoDCall), an R-based algorithm for standardized threshold determination, was developed, ensuring consistency of the ddPCR results. Implementation of a robust internal control, i.e., the 4Plex, and an algorithm for automated threshold determination, PoDCall, in methylation-specific ddPCR increase the precision of DNA methylation analysis.

Young and Older Adults’ Beliefs about Effective Ways to Mitigate Age-Related Memory Decline

PubMed Central

Horhota, Michelle; Lineweaver, Tara; Ositelu, Monique; Summers, Kristi; Hertzog, Christopher

2013-01-01

This study investigated whether young and older adults vary in their beliefs about the impact of various mitigating factors on age-related memory decline. Eighty young (ages 18–23) and eighty older (ages 60–82) participants reported their beliefs about their own memory abilities and the strategies that they use in their everyday lives to attempt to control their memory. Participants also reported their beliefs about memory change with age for hypothetical target individuals who were described as using (or not using) various means to mitigate memory decline. There were no age differences in personal beliefs about control over current or future memory ability. However, the two age groups differed in the types of strategies they used in their everyday life to control their memory. Young adults were more likely to use internal memory strategies, whereas older adults were more likely to focus on cognitive exercise and maintaining physical health as ways to optimize their memory ability. There were no age differences in rated memory change across the life span in hypothetical individuals. Both young and older adults perceived strategies related to improving physical and cognitive health as effective means of mitigating memory loss with age, whereas internal memory strategies were perceived as less effective means for controlling age-related memory decline.

Motivating contributions to online forums: can locus of control moderate the effects of interface cues?

PubMed

Kim, Hyang-Sook; Sundar, S Shyam

2016-01-01

In an effort to encourage users to participate rather than lurk, online health forums provide authority badges (e.g., guru) to frequent contributors and popularity indicators (e.g., number of views) to their postings. Studies have shown the latter to be more effective, implying that bulletin-board users are motivated by external validation of their contributions. However, no consideration has yet been given to individual differences in the influence of such popularity indicators. Personality psychology suggests that individuals with external, rather than internal, locus of control are more likely to be other-directed and therefore more likely to be motivated by interface cues showing the bandwagon effect of their online posts. We investigate this hypothesis by analyzing data from a 2 (high vs. low authority cue) × 2 (strong vs. weak bandwagon cue) experiment with an online health community. Results show that strong bandwagon cues promote sense of community among users with internal, rather than external, locus of control. When bandwagon cues are weak, bestowal of high authority serves to heighten their sense of agency. Contrary to prediction, weak bandwagon cues appear to promote sense of community and sense of agency among those with external locus of control. Theoretical and practical implications are discussed.

We evaluated the effect of terazosin in the improvement of lower urinary tract symptoms and flank pain in patients with internal ureteral stents. In this double-blind randomized clinical trial, 73 patients with unilateral ureteral stone and hydroureteronephrosis who underwent insertion of an internal ureteral stent after transureteral lithotripsy (TUL) were randomized into two groups. 37 patients received terazosin 2 mg (once nightly) for 4 weeks and 36 patients received placebo for the same time duration. After 4 weeks, all patients were asked about the incidence of frequency, nocturia and urgency by an International Prostate Symptom Score (IPSS) questionnaire, flank pain and pain during urination by a visual analog scale (VAS) score, and hematuria. The mean VAS score was 2.21 in the terazosin group compared with 4.93 in the control group (p < 0.001). Nearly all the patients in the placebo group reported flank pain during urination but this was only reported in 54.5% of the patients in the terazosin group (p < 0.001). All criteria measured by the IPSS in the terazosin group were significantly lower than those in the placebo group (p = 0.0001). Administration of terazosin for patients with an internal ureteral stent relieved some stent-related symptoms such as flank pain, pain during voiding, frequency, nocturia and urgency, but had no effect on hematuria.

Toehold-mediated internal control to probe the near-field interaction between the metallic nanoparticle and the fluorophore

NASA Astrophysics Data System (ADS)

2014-10-01

Metallic nanoparticles (MNPs) are known to alter the emission of vicinal fluorophores through the near-field interaction, leading to either fluorescence quenching or enhancement. Much ambiguity remains in the experimental outcome of such a near-field interaction, particularly for bulk colloidal solution. It is hypothesized that the strong far-field interference from the inner filter effect of the MNPs could mask the true near-field MNP-fluorophore interaction significantly. Thus, in this work, a reliable internal control capable of decoupling the near-field interaction from far-field interference is established by the use of the DNA toehold concept to mediate the in situ assembly and disassembly of the MNP-fluorophore conjugate. A model gold nanoparticle (AuNP)-Cy3 system is used to investigate our proposed toehold-mediated internal control system. The maximum fluorescence enhancement is obtained for large-sized AuNP (58 nm) separated from Cy3 at an intermediate distance of 6.8 nm, while fluorescence quenching is observed for smaller-sized AuNP (11 nm and 23 nm), which is in agreement with the theoretical values reported in the literature. This work shows that the toehold-mediated internal control design can serve as a central system for evaluating the near-field interaction of other MNP-fluorophore combinations and facilitate the rational design of specific MNP-fluorophore systems for various applications.Metallic nanoparticles (MNPs) are known to alter the emission of vicinal fluorophores through the near-field interaction, leading to either fluorescence quenching or enhancement.

Skirko, Jonathan R.; Weaver, Edward M; Perkins, Jonathan; Kinter, Sara; Sie, Kathleen C.Y.

2018-01-01

Objective Modify the existing 45-item velopharyngeal insufficiency (VPI) quality of life (QOL) instrument (VPIQL), assess the modified instrument for reliability and provide further validation. There are patient and parent versions of the instrument. Design Validation convenience sample from a previously conducted pilot study. Setting Two academic tertiary referral medical centers. Participants De-identified data were used from 29 subjects with VPI and 29 control subjects age 5–17 years, and parents. Outcome measures Subjects and parents completed VPIQL and a generic pediatric QOL instrument (PedsQL4-0). Data Analysis Twenty-two items were removed from the VPIQL for ceiling effects, floor effects, and redundancy, to produce the modified instrument, VPI Effects on Life Outcomes (VELO) instrument. VELO was tested for internal consistency (Chronbach’s alpha), discriminant validity (paired t-test with control subjects), and concurrent validity (Pearson correlation with the PedsQL4-0). These analyses were also completed for parents. Results The 45-item VPIQL instrument was reduced to the 23-item VELO instrument. The VELO had excellent internal consistency (Chronbach’s alpha 0.96 for parents and 0.95 for VPI subjects). The VELO discriminated well between VPI and control subjects, with mean score (SD) was significantly lower (worse) for VPI subjects (67.6 [23.9]) than for control subjects (97.0 [5.2]) (p<0.0001). The VELO total score was significantly correlated with the PedsQL4.0 (r=0.73) among subjects with VPI. Similar results were seen in parent responses. Conclusions The VELO is a 23-item QOL instrument that was designed to measure and follow QOL in subjects with VPI, with less burden than the original VPIQL. VELO demonstrates internal consistency, disciminant validty, and concurrent validity with the PedsQL4-0. PMID:23069823

Lithium and quetiapine are effective treatments for bipolar disorder, but their potential neuroprotective effects in humans remain unclear. A single blinded equivalence randomized controlled maintenance trial was conducted in a prospective cohort of first-episode mania (FEM) patients (n=26) to longitudinally compare the putative protective effects of lithium and quetapine on grey and white matter volume. A healthy control sample was also collected (n=20). Using structural MRI scans, voxel-wise grey and white matter volumes at baseline and changes over time in response to treatment were investigated. Patients were assessed at three time points (baseline, 3 and 12-month follow-up), whereas healthy controls were assessed at two time points (baseline and 12-month follow-up). Patients were randomized to lithium (serum level 0.6 mmol l−1, n=20) or quetiapine (flexibly dosed up to 800 mg per day, n=19) monotherapy. At baseline, compared with healthy control subjects, patients with FEM showed reduced grey matter in the orbitofrontal cortex, anterior cingulate, inferior frontal gyrus and cerebellum. In addition, patients had reduced internal capsule white matter volume bilaterally (t1,66>3.20, P<0.01). Longitudinally, there was a significant treatment × time effect only in the white matter of the left internal capsule (F2,112=8.54, P<0.01). Post hoc testing showed that, compared with baseline, lithium was more effective than quetiapine in slowing the progression of white matter volume reduction after 12 months (t1,24=3.76, P<0.01). Our data support the role of lithium but not quetiapine therapy in limiting white matter reduction early in the illness course after FEM. PMID:28117843

Characterizing tobacco control mass media campaigns in England

Aims To characterize publically funded tobacco control campaigns in England between 2004 and 2010 and to explore if they were in line with recommendations from the literature in terms of their content and intensity. International evidence suggests that campaigns which warn of the negative consequences of smoking and feature testimonials from real-life smokers are most effective, and that four exposures per head per month are required to reduce smoking prevalence. Design Characterization of tobacco control advertisements using a theoretically based framework designed to describe advertisement themes, informational and emotional content and style. Study of the intensity of advertising and exposure to different types of advertisement using data on population-level exposure to advertisements shown during the study period. Setting England. Measurements Television Ratings (TVRs), a standard measure of advertising exposure, were used to calculate exposure to each different campaign type. Findings A total of 89% of advertising was for smoking cessation; half of this advertising warned of the negative consequences of smoking, while half contained how-to-quit messages. Acted scenes featured in 72% of advertising, while only 17% featured real-life testimonials. Only 39% of months had at least four exposures to tobacco control campaigns per head. Conclusions A theory-driven approach enabled a systematic characterization of tobacco control advertisements in England. Between 2004 and 2010 only a small proportion of tobacco control advertisements utilized the most effective strategies—negative health effects messages and testimonials from real-life smokers. The intensity of campaigns was lower than international recommendations. PMID:23834209

How has the economic downturn affected communities and implementation of science-based prevention in the randomized trial of communities that care?

2013-06-01

This study examined implications of the economic downturn that began in December 2007 for the Community Youth Development Study (CYDS), a longitudinal randomized controlled trial of the Communities That Care (CTC) prevention system. The downturn had the potential to affect the internal validity of the CYDS research design and implementation of science-based prevention in study communities. We used archival economic indicators and community key leader reports of economic conditions to assess the extent of the economic downturn in CYDS communities and potential internal validity threats. We also examined whether stronger economic downturn effects were associated with a decline in science-based prevention implementation. Economic indicators suggested the downturn affected CYDS communities to different degrees. We found no evidence of systematic differences in downturn effects in CTC compared to control communities that would threaten internal validity of the randomized trial. The Community Economic Problems scale was a reliable measure of community economic conditions, and it showed criterion validity in relation to several objective economic indicators. CTC coalitions continued to implement science-based prevention to a significantly greater degree than control coalitions 2 years after the downturn began. However, CTC implementation levels declined to some extent as unemployment, the percentage of students qualifying for free lunch, and community economic problems worsened. Control coalition implementation levels were not related to economic conditions before or after the downturn, but mean implementation levels of science-based prevention were also relatively low in both periods.

False responses of Renilla luciferase reporter control to nuclear receptor TR4.

PubMed

Zhang, Dongyun; Atlasi, Sam S; Patel, Krishna K; Zhuang, Zihao; Heaney, Anthony P

2017-06-01

Renilla luciferase reporter is a widely used internal control in dual luciferase reporter assay system, where its transcription is driven by a constitutively active promoter. However, the authenticity of the Renilla luciferase response in some experimental settings has recently been questioned. Testicular receptor 4 (TR4, also known as NR2C2) belongs to the subfamily 2 of nuclear receptors. TR4 binds to a direct repeat regulatory element in the promoter of a variety of target genes and plays a key role in tumorigenesis, lipoprotein regulation, and central nervous system development. In our experimental system using murine pituitary corticotroph tumor AtT20 cells to investigate TR4 actions on POMC transcription, we found that overexpression of TR4 resulted in reduced Renilla luciferase expression whereas knockdown TR4 increased Renilla luciferase expression. The TR4 inhibitory effect was mediated by the TR4 DNA-binding domain and behaved similarly to the GR and its agonist, Dexamethasone. We further demonstrated that the chimeric intron, commonly present in various Renilla plasmid backbones such as pRL-Null, pRL-SV40, and pRL-TK, was responsible for TR4's inhibitory effect. The results suggest that an intron-free Renilla luciferase reporter may provide a satisfactory internal control for TR4 at certain dose range. Our findings advocate caution on the use of Renilla luciferase as an internal control in TR4-directed studies to avoid misleading data interpretation.

We found no evidence of systematic differences in downturn effects in CTC compared to control communities that would threaten internal validity of the randomized trial. The Community Economic Problems scale was a reliable measure of community economic conditions, and it showed criterion validity in relation to several objective economic indicators. CTC coalitions continued to implement science-based prevention to a significantly greater degree than control coalitions 2 years after the downturn began. However, CTC implementation levels declined to some extent as unemployment, the percentage of students qualifying for free lunch, and community economic problems worsened. Control coalition implementation levels were not related to economic conditions before or after the downturn, but mean implementation levels of science-based prevention were also relatively low in both periods.

Research has demonstrated clear advantages of using an external focus of attention in postural control tasks, presumably since it allows a more automatic control of posture to emerge. However, the influence of cognitive tasks on postural stability has produced discordant results. This study aimed to compare the effects of an internal focus of attention, an external focus of attention and a continuous cognitive task on postural control. Twenty healthy participants (21.4±2.6 years) were recruited for this study. They were asked to stand quietly on a force platform with their feet together in three different attentional focus conditions: an internal focus condition (minimizing movements of the hips), an external focus condition (minimizing movements of markers placed on the hips) and a cognitive task condition (silently counting the total number of times a single digit was verbalized in a 3-digit sequence comprised of 30 numbers). Results demonstrated improved stability while performing the cognitive task as opposed to the internal and external focus conditions, as evidenced by a reduction in sway area, sway variability in the anterior-posterior (AP) and medial-lateral (ML) directions, and mean velocity (ML only). Results suggest that the use of a continuous cognitive task permits attention to be withdrawn from the postural task, thereby facilitating a more automatic control of posture.

Background Several authors suggested that gravitational forces are centrally represented in the brain for planning, control and sensorimotor predictions of movements. Furthermore, some studies proposed that the cerebellum computes the inverse dynamics (internal inverse model) whereas others suggested that it computes sensorimotor predictions (internal forward model). Methodology/Principal Findings This study proposes a model of cerebellar pathways deduced from both biological and physical constraints. The model learns the dynamic inverse computation of the effect of gravitational torques from its sensorimotor predictions without calculating an explicit inverse computation. By using supervised learning, this model learns to control an anthropomorphic robot arm actuated by two antagonists McKibben artificial muscles. This was achieved by using internal parallel feedback loops containing neural networks which anticipate the sensorimotor consequences of the neural commands. The artificial neural networks architecture was similar to the large-scale connectivity of the cerebellar cortex. Movements in the sagittal plane were performed during three sessions combining different initial positions, amplitudes and directions of movements to vary the effects of the gravitational torques applied to the robotic arm. The results show that this model acquired an internal representation of the gravitational effects during vertical arm pointing movements. Conclusions/Significance This is consistent with the proposal that the cerebellar cortex contains an internal representation of gravitational torques which is encoded through a learning process. Furthermore, this model suggests that the cerebellum performs the inverse dynamics computation based on sensorimotor predictions. This highlights the importance of sensorimotor predictions of gravitational torques acting on upper limb movements performed in the gravitational field. PMID:19384420

Self-organized internal architectures of chiral micro-particles

The internal architecture of polymeric self-assembled chiral micro-particles is studied by exploring the effect of the chirality, of the particle sizes, and of the interface/surface properties in the ordering of the helicoidal planes. The experimental investigations, performed by means of different microscopy techniques, show that the polymeric beads, resulting from light induced polymerization of cholesteric liquid crystal droplets, preserve both the spherical shape and the internal self-organized structures. The method used to create the micro-particles with controlled internal chiral architectures presents great flexibility providing several advantages connected to the acquired optical and photonics capabilities and allowing to envisage novel strategies for the development of chiral colloidal systems and materials.

International Space Station Attitude Control and Energy Storage Experiment: Effects of Flywheel Torque

NASA Technical Reports Server (NTRS)

Roithmayr, Carlos M.

1999-01-01

The Attitude Control and Energy Storage Experiment is currently under development for the International Space Station; two counter-rotating flywheels will be levitated with magnetic bearings and placed in vacuum housings. The primary objective of the experiment is to store and discharge energy, in combination with existing batteries, into the electrical power system. The secondary objective is to use the flywheels to exert torque on the Station; a simple torque profile has been designed so that the Station's Control Moment Gyroscopes will be assisted in maintaining torque equilibrium attitude. Two energy storage contingencies could result in the inadvertent application of torque by the flywheels to the Station: an emergency shutdown of one flywheel rotor while the other remains spinning, and energy storage with only one rotor instead of the counterrotating pair. Analysis of these two contingencies shows that attitude control and the microgravity environment will not be adversely affected.

Zero-sum two-player game theoretic formulation of affine nonlinear discrete-time systems using neural networks.

PubMed

Mehraeen, Shahab; Dierks, Travis; Jagannathan, S; Crow, Mariesa L

2013-12-01

In this paper, the nearly optimal solution for discrete-time (DT) affine nonlinear control systems in the presence of partially unknown internal system dynamics and disturbances is considered. The approach is based on successive approximate solution of the Hamilton-Jacobi-Isaacs (HJI) equation, which appears in optimal control. Successive approximation approach for updating control and disturbance inputs for DT nonlinear affine systems are proposed. Moreover, sufficient conditions for the convergence of the approximate HJI solution to the saddle point are derived, and an iterative approach to approximate the HJI equation using a neural network (NN) is presented. Then, the requirement of full knowledge of the internal dynamics of the nonlinear DT system is relaxed by using a second NN online approximator. The result is a closed-loop optimal NN controller via offline learning. A numerical example is provided illustrating the effectiveness of the approach.

The Influence of Microbiology on Spacecraft Design and Controls: A Historical Perspective of the Shuttle and International Space Station Programs

Castro, Victoria A.; Bruce, Rebekah J.; Ott, C. Mark; Pierson, D. L.

2006-01-01

For over 40 years, NASA has been putting humans safely into space in part by minimizing microbial risks to crew members. Success of the program to minimize such risks has resulted from a combination of engineering and design controls as well as active monitoring of the crew, food, water, hardware, and spacecraft interior. The evolution of engineering and design controls is exemplified by the implementation of HEPA filters for air treatment, antimicrobial surface materials, and the disinfection regimen currently used on board the International Space Station. Data from spaceflight missions confirm the effectiveness of current measures; however, fluctuations in microbial concentrations and trends in contamination events suggest the need for continued diligence in monitoring and evaluation as well as further improvements in engineering systems. The knowledge of microbial controls and monitoring from assessments of past missions will be critical in driving the design of future spacecraft.

Carr, Stuart C; McWha, Ishbel; Maclachlan, Malcolm; Furnham, Adrian

2010-10-01

Despite the rhetoric of a single global economy, professionals in poorer countries continue to be remunerated differently depending on whether they are compensated at a local vs. international rate. Project ADDUP (Are Development Discrepancies Undermining Performance?) surveyed 1290 expatriate and local professionals (response rate = 47%) from aid, education, government, and business sectors in (1) Island Nations (Papua New Guinea, Solomon Islands), (2) landlocked economies (Malaŵi, Uganda), and (3) emerging economies (India, China). Difference in pay was estimated using purchasing power parity, from the World Bank's World Development Indicators 2007. Psychological measures included self-reported pay and benefits (remuneration), self-attributed ability, remuneration comparison, sense of justice in remuneration, remuneration-related motivation, thoughts of turnover and thoughts about international mobility. We included control measures of candour, culture shock, cultural values (horizontal/vertical individualism/collectivism), personality (from the "big five"), job satisfaction and work engagement. Controlling for these and country (small effects) and organization effects (medium), (a) pay ratios between international and local workers exceeded what were perceived to be acceptable pay thresholds among respondents remunerated locally; who also reported a combination of a sense of relative (b) injustice and demotivation; which (c) together with job satisfaction/work engagement predicted turnover and international mobility. These findings question the wisdom of dual salary systems in general, expose and challenge a major contradiction between contemporary development policy and practice, and have a range of practical, organizational, and theoretical implications for poverty reduction work.

Successful control of internal phosphorus loading after sediment dredging for 6years: A field assessment using high-resolution sampling techniques.

The effectiveness of sediment dredging for the control of internal phosphorus (P) loading, was investigated seasonally in the eutrophic Lake Taihu. The high-resolution dialysis (HR-Peeper) and diffusive gradients in thin films (DGT) techniques were used to measure the concentrations of soluble Fe(II) and soluble reactive P (SRP) as well as DGT-labile Fe/P in the non-dredging and post-dredging sediments. The P resupply kinetics from sediment solids were interpreted using DGT Induced Fluxes in Sediments (DIFS) modeling. The results showed no obvious improvement in water and sediment quality after dredging for 6years, due to their geographical proximity (a line distance of approximately 9km). However, dredging significantly decreased the concentrations of soluble Fe(II)/SRP and DGT-labile Fe/P in sediments, with effects varying at different depths below the sediment-water interface; More pronounced effects appeared in January and April. The diffusive flux of pore water SRP from sediments decreased from 0.746, 4.08 and 0.353mg/m 2 /d to 0.174, 1.58 and 0.048mg/m 2 /d in April, July and January, respectively. DIFS modeling indicated that the P retention capability of sediment solids was improved in April in post-dredging site. Positive correlations between pore water soluble Fe(II) and SRP as well as between DGT-labile Fe and P, reflect the key role of Fe redox cycling in regulating dredging effectiveness. This effect is especially important in winter and spring, while in summer and autumn, the decomposition of algae promoted the release of P from sediments and suppressed dredging effectiveness. Overall, the high-resolution HR-Peeper and DGT measurements indicated a successful control of internal P loading by dredging, and the post-dredging effectiveness was suppressed by algal bloom.

Nutritional health plays a crucial role in determining successful ageing and differs by different living area. Although nutritional interventions have long been advocated, little research has directly assessed the effectiveness of nutritional interventions on community-dwelling older adults in urban and rural areas and compared intervention effects on these two populations. To examine the effectiveness of a 12-week dietary self-management programme for salt-, fluid-, fat- and cholesterol-intake behaviours of community-dwelling older adults and to compare these effects in rural- and urban-dwelling older adults. For this quasi-experimental two-group study, older adults (≥65 years old) were recruited from two randomly selected public health centres in a rural north-eastern county and a northern city of Taiwan from January through December 2011. Outcomes included nutritional status, nutritional self-efficacy and health locus of control. Data were collected at baseline and 12 weeks later. To compare changes in outcome variables over time between the control (usual care) and intervention (nutritional programme) groups and between the urban- and rural-dwelling participants in the experimental group, we used generalised estimating equation analysis. Of the 129 participants, 120 completed this study (58 in the intervention group and 62 in the control group). After 12 weeks, the intervention group had significantly better nutritional status and higher internal health locus of control than the control group. Moreover, older rural participants who received the intervention tended towards higher nutritional self-efficacy and internal health locus of control than their urban counterparts. Our research findings support the positive effect of our nutritional self-management programme for community-dwelling older adults. The knowledge gained from this study can help stakeholders recognise the need for healthcare policy to establish effective strategies and sustainable intervention programmes for this population, especially those living in rural areas. © 2016 Nordic College of Caring Science.

Simple method for production of internal control DNA for Mycobacterium tuberculosis polymerase chain reaction assays.

PubMed Central

deWit, D; Wootton, M; Allan, B; Steyn, L

1993-01-01

A simple method for the production of internal control DNA for two well-established Mycobacterium tuberculosis polymerase chain reaction assays is described. The internal controls were produced from Mycobacterium kansasii DNA with the same primers but at a lower annealing temperature than that used in the standard assays. In both assays, therefore, the internal control DNA has the same primer-binding sequences at the target DNA. One-microgram quantities of internal control DNA which was not contaminated with target DNA could easily be produced by this method. The inclusion of the internal control in the reaction mixture did not affect the efficiency of amplification of the target DNA. The method is simple and rapid and should be adaptable to most M. tuberculosis polymerase chain reaction assays. Images PMID:8370752

A method and means of minimizing the effect of elastic valve recoil in impact applications, such as percussive drilling, where sliding spool valves used inside the percussive device are subject to poor positioning control due to elastic recoil effects experienced when the valve impacts a stroke limiting surface. The improved valve design reduces the reflected velocity of the valve by using either an energy damping material, or a valve assembly with internal damping built-in, to dissipate the compression stress wave produced during impact.

Although rotator-cuff muscle contraction plays an important role in stabilizing the glenohumeral joint, little is known about the role of these muscles in the pathophysiology of recurrent anterior instability. We intended to analyze the association between isokinetic internal rotator and external rotator muscle strength and glenohumeral joint instability in patients with recurrent anterior instability that was not previously treated surgically. We enrolled thirty-seven patients with unilateral recurrent anterior posttraumatic shoulder dislocation and eleven healthy nonathletic subjects in this controlled study. The association between internal rotator and external rotator strength and shoulder instability was analyzed by side-to-side comparisons and comparisons with a control group. Isokinetic internal rotator and external rotator strength was evaluated with a Con-Trex dynamometer, with the subject seated and the shoulder abducted 45° in the scapular plane. Tests were performed at 180°/s, 120°/s, and 60°/s in concentric mode for both sides. Peak torque normalized to body weight and external rotator to internal rotator ratio were calculated for each angular velocity. Clinical and isokinetic evaluation was done by the same rehabilitation physician. The association between shoulder instability and internal rotator and external rotator strength was associated with side-to-side differences (p < 0.05). Compared with a control group, strength values were lower on the pathological shoulder side of the patients with shoulder instability than on the healthy contralateral shoulder of control subjects at 180°/s and 120°/s (p < 0.05). The side-to-side differences were increased when the nondominant upper-extremity side was involved and were decreased when the dominant side was involved. There was no association between glenohumeral joint instability and external rotator to internal rotator ratio. Internal rotator and external rotator weakness was associated with recurrent anterior instability, and side-to-side differences depended on the side of hand dominance. Use of a control group may help in the analysis of the influence of constraints on shoulder strength. Further prospective studies are necessary to determine whether the weakness is a cause or an effect of the instability.

A compound control strategy combining velocity compensation with ADRC of electro-hydraulic position servo control system.

2014-11-01

In order to enhance the anti-jamming ability of electro-hydraulic position servo control system at the same time improve the control precision of the system, a compound control strategy that combines velocity compensation with Active Disturbance Rejection Controller (ADRC) is proposed, and the working principle of the compound control strategy is given. ADRC controller is designed, and the extended state observer is used for observing internal parameters uncertainties and external disturbances, so that the disturbances of the system are suppressed effectively. Velocity compensation controller is designed and the compensation model is derived to further improve the positioning accuracy of the system and to achieve the velocity compensation without disturbance. The compound control strategy is verified by the simulation and experiment respectively, and the simulation and experimental results show that the electro-hydraulic position servo control system with ADRC controller can effectively inhibit the external disturbances, the precise positioning control is realized after introducing the velocity compensation controller, and verify that the compound control strategy is effective.

Varicella zoster virus (VZV) is a neurotropic α-herpesvirus that causes chickenpox and establishes life-long latency in the cranial nerve and dorsal root ganglia of the host. To date, VZV is the only virus consistently reported to have an inverse association with glioma. The Glioma International Case-Control Study (GICC) is a large, multisite consortium with data on 4533 cases and 4171 controls collected across five countries. Here, we utilized the GICC data to confirm the previously reported associations between history of chickenpox and glioma risk in one of the largest studies to date on this topic. Using two-stage random-effects restricted maximum likelihood modeling, we found that a positive history of chickenpox was associated with a 21% lower glioma risk, adjusting for age and sex (95% confidence intervals (CI): 0.65-0.96). Furthermore, the protective effect of chickenpox was stronger for high-grade gliomas. Our study provides additional evidence that the observed protective effect of chickenpox against glioma is unlikely to be coincidental. Future studies, including meta-analyses of the literature and investigations of the potential biological mechanism, are warranted. © 2016 The Authors.

A prospective study was performed with two internal medicine in-patient teams. Team 1 included a CML who accompanied the team on daily rounds. The CML answered questions posed at the point of care immediately or in emails post-rounds. Patients on Team 2, which did not include a CML, as well as patients who did not require consultation by the CML on Team 1, served as the control population. Numerous clinical and library metrics were gathered on each question. Patients on Team 1 who required an answer to a clinical question were more ill and had a longer length of stay, higher costs, and higher readmission rates compared to those in the control group. Using a matched pair analysis, we showed no difference in clinical outcomes between the intervention group and the control group. This study is the largest attempt to prospectively measure changes in patient outcomes when physicians were accompanied by a CML on rounds. This approach may serve as a model for further studies to define when and how CMLs are most effective.

NASA flight controllers have always worked in a very demanding environment, but the International Space Station (ISS) poses even more challenges than prior missions. A recent NASA/Ames survey by Parke and Orasanu of NASA/Johnson flight controllers uncovered concerns about communications problems between American personnel and their international counterparts. To better understand these problems, we interviewed 14 senior and 12 junior ISS flight controllers at NASA/Johnson about leadership and cultural challenges they face and strategies for addressing these challenges. The qualitative interview data were coded and tabulated. Here we present quantitative analyses testing for differences between junior and senior controllers. Based on nonparametric statistical tests comparing responses across groups, the senior controllers were significantly more aware of the impact of working in dispersed teams, the context of constant change, and the upcoming multilateral challenges, while junior controllers were more aware of language and cultural issues. We consider our findings in light of other studies of controllers and other known differences between senior and junior controllers. For example, the fact that senior controllers had their formative early experience controlling pre-ISS short-duration Shuttle missions seems to have both positive and negative aspects, which are supported by our data. Our findings may also reflect gender differences, but we cannot unconfound this effect in our data because all the senior respondents were males. Many of the junior-senior differences are not only due to elapsed time on the job, but also due to a cohort effect. The findings of this study should be used for training curricula tailored differently for junior and senior controllers.

We conducted a meta-analysis of published retrospective studies and compared the effectiveness of pars plana vitrectomy with and without internal limiting membrane (ILM) peeling for idiopathic epiretinal membrane (IERM). The results revealed that patients in the IERM+ILM peeling group had better BCVA after surgery within 12 months than those in IERM peeling group. But patients in the IERM peeling group showed better BCVA in the 18th month. More retrospective studies or randomized controlled trials are required to investigate and compare the long-term effect of IERM removal with and without ILM peeling. PMID:26693348

2017-01-01

Atypical respiratory sinus arrhythmia (RSA), a biomarker of emotion dysregulation, is associated with both externalizing and internalizing behaviors. In addition, social adversity and gender may moderate this association. In this study, we investigated if RSA (both resting RSA and RSA reactivity in an emotion regulation task) predicts externalizing and/or internalizing behaviors and the extent to which social adversity moderates this relationship. Two hundred and fifty-three children (at Time 1, mean age = 9.05, SD = 0.60, 48% boys) and their caregivers from the community participated in this study. Resting RSA and RSA reactivity were assessed, and caregivers reported children’s externalizing and internalizing behaviors at both Time 1 and Time 2 (1 year later). We found that lower resting RSA (but not RSA reactivity) at Time 1 was associated with increased externalizing and internalizing behaviors at Time 2 in boys, even after controlling for the effects of Time 1 behavioral problems and Time 2 age. Moreover, there was a significant interaction effect between Time 1 resting RSA and social adversity such that lower resting RSA predicted higher externalizing and internalizing behaviors in boys only under conditions of high social adversity. Follow-up analyses revealed that these predictive effects were stronger for externalizing behavior than for internalizing behavior. No significant effects were found for girls. Our findings provide further evidence that low resting RSA may be a transdiagnostic biomarker of emotion dysregulation and a predisposing risk factor for both types of behavior problems, in particular for boys who grow up in adverse environments. We conclude that biosocial interaction effects and gender differences should be considered when examining the etiological mechanisms of child psychopathology. PMID:28955262

Surface engineering of a hydrogel nanoparticle (NP) with the tumor-targeting ligand, F3 peptide, enhances both the NP's binding affinity for, and internalization by, nucleolin overexpressing tumor cells. Remarkably, the F3-functionalized NPs consistently exhibited significantly lower trafficking to the degradative lysosomes than the non-functionalized NPs, in the tumor cells, after internalization. This is attributed to the non-functionalized NPs, but not the F3-functionalized NPs, being co-internalized with Lysosome-associated Membrane Protein-1 (LAMP1) from the surface of the tumor cells. Furthermore, it is shown that the intracellular trafficking of the F3-functionalized NPs differs significantly from that of the molecular F3 peptides (untethered to NPs). This has important implications for designing effective, chemically-responsive, controlled-release and multifunctional nanodrugs for multi-drug-resistant cancers.Surface engineering of a hydrogel nanoparticle (NP) with the tumor-targeting ligand, F3 peptide, enhances both the NP's binding affinity for, and internalization by, nucleolin overexpressing tumor cells.

Effects of Buckling Knockdown Factor, Internal Pressure and Material on the Design of Stiffened Cylinders

NASA Technical Reports Server (NTRS)

Lovejoy, Andrew E.; Hilburger, Mark W.; Chunchu, Prasad B.

2010-01-01

A design study was conducted to investigate the effect shell buckling knockdown factor (SBKF), internal pressure and aluminum alloy material selection on the structural weight of stiffened cylindrical shells. Two structural optimization codes were used for the design study to determine the optimum minimum-weight design for a series of design cases, and included an in-house developed genetic algorithm (GA) code and PANDA2. Each design case specified a unique set of geometry, material, knockdown factor combinations and loads. The resulting designs were examined and compared to determine the effects of SBKF, internal pressure and material selection on the acreage design weight and controlling failure mode. This design study shows that use of less conservative SBKF values, including internal pressure, and proper selection of material alloy can result in significant weight savings for stiffened cylinders. In particular, buckling-critical cylinders with integrally machined stiffener construction can benefit from the use of thicker plate material that enables taller stiffeners, even when the stiffness, strength and density properties of these materials appear to be inferior.

This study examined the effects of a 6-week strength-training program on serve velocity in youth tennis players. Thirty competitive healthy and nationally ranked male junior tennis players (13 years of age) were randomly and equally divided into control and training groups. The training group performed 3 sessions (60-70 min) weekly for 6 weeks, comprising core strength, elastic resistance and medicine ball exercises. Both groups (control and training) also performed a supervised stretching routine at the end of each training session, during the 6 week intervention. Service velocity, service accuracy and shoulder internal/external rotation were assessed initially and at the end of the 6-week conditioning program for both, control and training groups. There was a significant improvement in the serve velocity for the training group (p = 0. 0001) after the intervention, whereas in the control group there were no differences between pre and post-tests (p = 0.29). Serve accuracy was not affected in the training group (p = 0.10), nor in the control group (p = 0.15). Shoulder internal/external rotation ROM significantly improved in both groups, training (p = 0.001) and control (p = 0.0001). The present results showed that a short- term training program for young tennis players, using minimum equipment and effort, can result in improved tennis performance (i.e., serve velocity) and a reduction in the risk of a possible overuse injury, reflected by an improvement in shoulder external/internal range of motion. Key PointsA short-term training program for young tennis players, using minimum equipment and effort, can result in improved tennis performance and a reduction in the risk of a possible overuse injury, reflected by an improvement in shoulder external/internal range of motionA combination of core stabilization, elastic resistance exercises, and upper body plyometric exercises (i.e., medicine ball throws), focussing on the primary muscle groups and stabilizers involved in tennis specific movement patterns, could be appropriate for development tennis playersStretching exercises are recommended in the cool-down phase following matches or training sessions.

The global nature of the threat posed by new and reemerging infectious diseases will require international cooperation in identifying, controlling, and preventing these diseases. Because of this need for international cooperation, international law will certainly play a role in the global strategy for the control of emerging diseases. Recognizing this fact, the World Health Organization has already proposed revising the International Health Regulations. This article examines some basic problems that the global campaign against emerging infectious diseases might face in applying international law to facilitate international cooperation. The international legal component of the global control strategy for these diseases needs careful attention because of problems inherent in international law, especially as it applies to emerging infections issues.

This paper describes NASA-HDBK-4002, "Avoiding Problems Caused by Spacecraft On-Orbit Internal Charging Effects". The handbook includes a description of internal charging and why it is of concern to spacecraft designers. It also suggests how to determine when a project needs to consider internal spacecraft charging, it contains an electron penetration depth chart, rationale for a critical electron flux criterion, a worst-case geosynchronous electron plasma spectrum, general design guidelines, quantitative design guidelines, and a typical materials characteristics list. Appendices include a listing of some environment codes, electron transport codes, a discussion of geostationary electron plasma environments, a brief description of electron beam and other materials tests, and transient susceptibility tests. The handbook will be in the web page, hftp://standards.nasa.gov. A prior document, NASA TP2361 "Design Guidelines for Assessing and controlling Spacecraft Charging Effects", 1984, is in use to describe mitigation techniques for the effects of surface charging of satellites in space plasma environments. HDBK-4002 is meant to complement 2361 and together, the pair of documents describe both cause and mitigation designs for problems caused by energetic space plasmas.
